Yuba is the first choice for many families to take a bath. Yuba currently on the market can be divided into the following three types according to its heating principle:
1. Bulb series Yuba: With the special infrared timely heating bulb as the heat source, the indoor air can be directly heated by radiation, and a wide range of heating effects can be obtained instantly without preheating.
2.PTC (a kind of ceramic electric heating element) series Yuba: With PTC ceramic heating element as the heat source, it has the advantages of fast temperature rise, high thermal efficiency, no light emission, no naked flame, long service life and so on. It has double safety functions and is very safe and reliable.
3. Double-warm-current series Yuba: the far-infrared radiation heating bulb and PTC ceramic heating element are used for joint heating, which has faster heating speed and higher thermal efficiency.
[Edit this paragraph] The main types and prices of yuba
The development of Yuba: traditional bulb Yuba-PTC heater-ordinary carbon fiber Yuba-warm therapy companion.
Yuba's manufacturers are mainly concentrated in Jiaxing, Zhejiang, while others are scattered. Shanghai has the famous Yuba of Shanghai Longsheng Electric Appliances, and San Pu Yuba is in the north. Among them, there are more than 400 manufacturers who make light, warm wind and warm bath tyrants. However, there are not many manufacturers of carbon fiber. Brands mainly include BNN, Baolan, Tainan and Lee Tae. These brands only apply carbon fiber heating tubes to Yuba, which is called carbon fiber Yuba here, and the price is not very high. Because these brands all use common spare parts, they just regard this product as a model of their own Yuba products, and there is no large-scale research and development and promotion, so the model and appearance are relatively single. Jiangsu Balalei Electric Co., Ltd. began to invest in the research and development of carbon fiber hyperthermia products in 2005. The wavelength and thermal efficiency can be controlled by using professional carbon fiber technology and equipment monitoring with far infrared technology. This product is called BNN hyperthermia companion. From a large industry, it belongs to the bathroom heating industry, but unlike ordinary carbon fiber Yuba products, BNN is positioned in the middle and high-end consumer groups, with 30 models, and the channels are both home appliance chains and building materials chains. The price is between 700-2500 yuan, which is higher than that of ordinary Yuba. Sampu Yuba is the leader of light-warm and air-warm Yuba, and its box is 134mm, which is the thinnest on the market at present. Its air duct design includes the research results of GAFL in Tsinghua University, achieving the best noise-free and power-saving effect. However, due to its high price and consumers' incomprehension of the concept of thermotherapy, BNN's products do not occupy a large share in the market. At present, traditional Yuba is the main product.
[Edit this paragraph] How to choose a high-quality, safe and practical Yuba?
Because Yuba often works in a humid environment, it is not allowed to be sloppy when purchasing, otherwise it will endanger the personal safety of consumers. Therefore, consumers should be reminded to pay attention to the following points when purchasing Yuba:
1. Choose a safe and high-quality bathroom heater. The heating bulb, namely the infrared timely radiation lamp, has the advantages of wide heating range, fast heating speed and good effect, and can be instantly heated to 23-25℃ without preheating. Yuba has 2 lights and 4 lights, and each heating bulb has a power of about 275W, which can be independently controlled, and the 500 and 1 100W are high and low. When purchasing, we must pay attention to whether the heating lamp is safe enough and whether it is strictly waterproof and explosion-proof; The lamp holder should use double lines to prevent it from falling off. In addition, choose products with protective nets outside the heating bubble. The infrared heating bulb adopts hard explosion-proof glass, and its high-strength connection mode also prevents the danger of lamp holder and glass shell falling off. General manufacturers should strictly test the heating bubbles, that is, simulate the daily bathing situation, ensure that 100% passes the alternating experiment of cold and hot, and after electrifying 15 minutes, shower the heating bubbles with cold water at 4℃ to ensure that the average life of each heating bubble is over 5,000 hours. Yuba's heating bubble also uses a new type of internal negative pressure technology, even if the bulb is broken, it will only shrink into a ball and will not endanger the personal safety of consumers. Yuba lighting basically uses conventional 45W and 60W bulbs, which can be used as bathroom lighting. Any high-quality yuba with the above characteristics should be recorded in the product manual.
2, choose intelligent automatic negative ion bath bully. Choose to integrate heating, lighting, ventilation, blowing, wind guiding and air purification, and adopt built-in electric overheating protector, which can automatically shut down when the temperature rises to a certain degree; The technology of fresh negative ion generator can continuously generate fresh negative ions, avoid bacterial reproduction in the air and make the bathroom air fresher. The fan has low noise and powerful ventilation function, which can eliminate indoor dirty air, odor and moisture in time, enhance air circulation and keep the air fresh. Try to choose the headlight distance design, which has the advantage of increasing the distance between heating bubbles to make the heat dissipation surface wider, making the heat coverage area in the bathroom wider and the heat distribution more uniform. At the same time, the temperature can be flexibly adjusted by the remote controller.
3. Choose a Yuba with outstanding decoration. Yuba is installed on the top of the bathroom, which does not occupy the use space. The latest Yuba is more modern in thickness reduction, streamline modeling, color diversification and so on, and the decorative effect is also very good. The heating bulb is designed with low color temperature, with soft light and no irritation to eyes. This kind of Yuba has butterflies, stars, waves, rainbows, palaces and other fashionable shapes, which fully adopts the beauty of nature and can add some harmony to your bathroom. In addition, the unique combination of stainless steel and plastic materials is more suitable for decoration, which can perfectly match the beautiful bathroom space with unique personality.
4. Select the power according to the use area and height. Choosing a Yuba depends on its use area and the height of the bathroom. There are mainly two, three and four kinds of heating bulbs on the market now, and their application areas are different. Generally, the bathroom with two bulbs at a height of 2.6m is suitable for the bathroom of about 4 square meters, mainly for the old buildings with small bathrooms. Four-lamp Yuba is suitable for 6-8 square meters of bathrooms, mainly for families with new houses.
5, the use of materials and appearance process inspection. When you buy a Yuba, you should also pay attention to the inspection of the appearance technology level. Coating of stainless steel, painted parts, plastic parts, glass cups, electroplated parts, etc. Should be uniform and bright, without shedding, dents or serious scratches or extrusion marks, and have a beautiful appearance. Pay attention to identify fake and shoddy products when choosing. Their deception often uses fake trademarks and packaging, or the assembled brands pretend to be original goods, but the appearance technology of such goods is generally rough.
6. Master all kinds of cost performance when purchasing. Generally, the normal selling price of 4-lamp Yuba should be above 500 yuan, and it will rise according to the function and change. If it is lower than this price, we should consider its quality. Because Yuba's strict requirements for heating lamp technology also determine that the price of high-quality Yuba will not be very low. If consumers see 200-300 yuan or even four-lamp Yuba in the market, most of them are fake and shoddy products, because the price of an infrared heating bulb with qualified safety indicators should be above 50 yuan, four 200 yuan, and the price of other genuine accessories should be around 150 yuan. In addition, the manufacturer's profit and the lowest selling price should be above 500 yuan. Low-priced yuba can only use some low-priced raw materials to reduce the safety of yuba in order to reduce the cost. Consumers must not be fooled.
7. Choose the famous brand products of 3C certified professional factories. Some professional manufacturers with abundant technology and funds have developed famous brand products of electrical appliances, which are generally excellent in technology, stable in performance, safe and reliable. When purchasing, you should check whether there is 3C certification standard for household appliances in China, and the body or packaging of certified products should have 3C certification. There must also be a production license issued by the state, including factory name, address, date of manufacture, product certificate, inspector number, drawings, after-sales credit card, maintenance station address and telephone number.
At present, the popular brand-name products in Yuba market are: Baolan, Sambo, BNN Warm Therapy Companion, Yuepu, Chuchu, Mingzu, Feidiao and other brands.
8. Choose products with guaranteed after-sales service. Brand-name products produced by Yuba professional manufacturers and recognized by the city are generally guaranteed for one to three years and maintained for life. There are local maintenance service outlets, free installation and on-site maintenance. After the heating lamp and other spare parts fail, they can be replaced immediately, and the manufacturer will supply them for a long time, and the products will be upgraded free of charge. Therefore, consumers should choose products with perfect after-sales service.
[Edit this paragraph] Problems needing attention in using and installing Yuba
1, Yuba power distribution system should be standardized. The maximum power of Yuba can reach more than1100 W. Therefore, the power supply wiring for installing Yuba must be waterproof, preferably multi-wire copper core wire not less than1mm. All power supply wiring must be embedded in the wall with plastic concealed pipes, and no open wires are allowed. The power control switch of Yuba must be a qualified product with waterproof capacity greater than 10A, especially
2. Pay attention to the thickness of yuba. On the installation issue, consumers must pay attention to the thickness of Yuba when purchasing, which is generally around 20 cm. Because Yuba is to be installed on the roof, if Yuba is to be installed, it is necessary to add a layer of suspended ceiling under the roof, which is what we often call PVC suspended ceiling, so that the second half of Yuba can be sandwiched between two floors of the roof. If Yuba is too thick, it will be difficult to decorate.
Yuba should be installed in the center of the bathroom. Many families install it above the bathtub or shower, so the surface looks like it is heating up quickly in winter, but there are security risks. Because the infrared radiation lamp heats up quickly, it is easy to burn the human body if it is too close. The correct way is to install the Yuba in the center of the top of the bathroom, or slightly near the bathtub, which is safer and can maximize its function.
4. Yuba is forbidden to spray with water when working. Special attention should be paid when using: although the current Yuba is waterproof, it must not splash water in actual use. Yuba's waterproof light bulb has waterproof performance, but the metal fittings in the body can't do this, that is, the metal in the body is still conductive. If water is splashed, it will cause danger such as short circuit of power supply.
5. Avoid frequent switching and surrounding vibration. Don't turn on and off the Yuba frequently at ordinary times. There should be no big vibration around the Yuba during operation, otherwise it will affect the service life of the heating bubble. If there is any abnormality in the operation, stop the machine immediately, and it is not allowed to dismantle and repair it by itself. It must be inspected by professional technicians in the after-sales service and maintenance department.
6. Keep the bathroom clean and dry. After taking a shower, don't turn off the Yuba immediately, wait until the moisture in the bathroom is exhausted. Always keep the bathroom ventilated, clean and dry to prolong the service life of Yuba.
Three safety strategies for using Yuba
Security policy 1:
Choose high quality,
Brand's heating lamp Yuba
According to reports, the general Yuba heating bulbs are infrared timely radiation lamps, which heat up quickly and do no harm to the body. It can be heated to about 25℃ instantly. Generally, Yuba is divided into two light bulbs and four light bulbs, which should be purchased according to the size of its own bathroom space. If it is less than 5 square meters, a bathroom with two bulbs is generally enough, and a slightly larger bathroom can choose a bathroom with four bulbs. Nowadays, heating bulbs are generally waterproof and explosion-proof, and some heating bulbs have protective nets outside.
Yuba products generally integrate lighting, heating and ventilation. After installation, the whole bathroom often saves a lot of space. Generally speaking, the appearance color, size and style of Yuba should be consistent with the decoration style of the bathroom, so as to coordinate. In addition, because Yuba is an electrical appliance that is in close contact with people, once the quality is unqualified, electric leakage and electric shock will directly cause harm, so try to choose products with big brands, which can generally provide a three-year free warranty.
Security policy 2:
Don't use two kinds of bulbs at the same time.
When Yuba is turned on, four heating bulbs and lighting bulbs are used at the same time, which not only consumes electricity, but also is unsafe. The maximum power of four heating bulbs can reach 1 100 W, which may easily cause some old houses to trip if used for a long time. At the same time, the standing time under Yuba should not be too long, generally not more than half an hour, otherwise it will be easily injured by strong light radiation.
Because the brightness of the heating bulb is high enough, many manufacturers have designed the function of automatically turning off the lighting bulb when the heating bulb is turned on, but some early models did not have this function. To avoid waste, users should not turn on the lighting at the same time. And many users like reading in the bathroom. If you use high-brightness heating lamp as lighting, it is easy to hurt your eyes.
Security policy 3:
Installation should not be too low.
When installing Yuba, try to install it on the top of your head, not on the side of your body like some hotels. It's best not to be too low from the top of your head. Theoretically, it should be above 40 cm, so as to keep warm and not burn the skin.
Besides, don't spray water when Yuba is working. Although the current Yuba is composed of waterproof and high-temperature resistant light bulbs, the motor in the gap next to it is often afraid of getting wet, and the metal in the motor has strong conductivity, which is easy to cause short circuit of power supply and cause danger. In addition, the heating bulb of Yuba can reach 165 degrees after being turned on. Never touch it with your hands, otherwise it will be easy to burn, and try to avoid close contact with your baby.
[Edit this paragraph] The development of yuba industry in China.
China has been developing and producing Yuba since the mid-1990s, and Yuba enterprises represented by Opal, Mingzu and Feidiao have occupied the main share of the domestic Yuba market. Yuba has become an indispensable part of modern family fashion life.
Yuba is a small household appliance with low investment and high return, and its manufacturing capital and technical threshold are not high. Due to the influence of housing conditions, economic ability and consumption concept, Yuba market is mainly concentrated in large and medium-sized cities. With more and more advanced technology and perfect quality, Yuba's family ownership rate in China is increasing year by year.
With the development of yuba industry in China, some problems are increasingly exposed. For example, due to the lack of unified and detailed safety indicators and quality inspection and evaluation standards, some low-quality and shoddy products are flooding, which poses a great threat to the health and safety of consumers, while the state has not clearly defined the quality and safety indicators of the yuba industry, which seriously restricts the further development and quality improvement of the industry.
China yuba enterprises must seize the new development situation, strengthen scientific and technological innovation, build a standardized and complete price system and sales system, strengthen after-sales service level, create a variety of promotion channels, and make a unified plan for the national standards of yuba industry, which is also an inevitable choice for the future development of the industry.
With the change of consumers' concept and the improvement of living standards, the requirements for the appearance and applicability of Yuba products are getting higher and higher. Full of fashion sense, it is more suitable for modern home use, and the new metal panel with heat resistance, corrosion resistance and rust prevention will become the application trend of Yuba panel in the future.
In the context of the global financial crisis and the slowdown of economic growth, small household appliances stand out in the domestic household appliance industry where the overall growth rate has declined. In 2008, the sales of domestic small household appliances enterprises increased significantly in the first three quarters.
Different from traditional household appliances, the sales of small household appliances in China are still in the development stage. With the increase of consumer demand, there are more and more types and quantities of small household appliances, and the average profit rate of small household appliances is high, which also brings high benefits to enterprises. The profit rate and growth rate of small household appliances in China will increase to about 30% in the future.
[Edit this paragraph] Yuba radiation, light pollution and other serious problems.
The Black Boy of Eyes, Skin and Life-Yuba
First of all, infrared rays harm eyes and skin.
Infrared ray is a kind of thermal radiation, which will cause high temperature damage to human body. Strong infrared rays can cause skin damage, similar to burns. First the burning pain, then the burns.
Infrared rays can harm the eyes in several different situations:
The 1 infrared ray with the wavelength of 0.75 ~ 1.3 micron has a high transmittance to the cornea, which can cause damage to the fundus retina. In particular, infrared rays of about 1. 1 micron can make the anterior media (cornea, lens, etc. ) the eyes are not damaged and directly cause fundus retinal burns;
2. Almost all infrared rays with the wavelength of 1.9 micron are absorbed by the cornea, which will cause corneal burns (opacity and white spots);
3. Most of the energy of infrared ray with wavelength greater than 1.4 micron is absorbed by cornea and internal liquid, and cannot penetrate iris;
4. Only infrared rays below 1.3 micron can penetrate the iris, causing iris damage. If the human eye is exposed to infrared rays for a long time, it will lead to cataracts.
Of course, the way to protect your eyes is to keep your eyes away from the infrared front, or sit beside it, out of sight, or simply turn your back on it to keep warm and avoid its harm. Infants take a bath in the basin and look up. If there is a yuba on it, the child's eyes may be finished, and parents and children will be very painful in the future.
If there is a baby at home, don't let the child turn on the Yuba at the same time when taking a bath, otherwise it will cause permanent damage to the child's future vision.
Second, strong light can easily burn your eyes.
Guo, a professor of ophthalmology at Shengjing Hospital affiliated to China Medical University, said: Family bathrooms are generally heated by Yuba. When people take a bath in winter, four light bulbs are always on. The wattage of most Yuba bulbs is 275 watts, and the four bulbs add up to 1 100 watts. Strong light will cause light pollution. Frequent use of yuba for a long time can cause dizziness, insomnia, inattention and loss of appetite. This is because too bright light interferes with the central nervous system function of the human brain. There are also data showing that light pollution will weaken the visual function of infants and affect children's visual development.
Third, Yuba is not waterproof.
Yuba's waterproof light bulb has waterproof performance, but the lamps, exhaust fans, lighting lamps and other non-IP33 waterproof structural lamps are not waterproof, that is, the metal in the lamp body is still conductive. If water overflows, it will cause danger such as short circuit of power supply.
Fourth, Yuba is uncomfortable.
The working principle of Yuba is to raise the temperature of the bathroom by heating the heat radiation of the bubble. But it can only heat the irradiated local area, and can't make the whole bathroom warm, and the temperature in the bathroom is uneven. The heating mode of Yuba heating to raise the temperature and lower the temperature does not meet the comfort requirements of human body to feel warm feet and cool head, and it is easy to cause respiratory tract infection for the elderly, children and the weak. This is why people who have used Yuba do not feel warm and comfortable.
Five, the quality of yuba is mixed, fake and shoddy, so be careful when buying.
According to the survey data released by AQSIQ, nearly 40% of indoor heater products (including Yuba) are unqualified. The results of spot checks in Shanxi and Sichuan provinces show that the qualified rate of yuba is only about 50%. As a product with China characteristics (there is no such product abroad), it has entered the market for more than ten years, and there is no industry standard for yuba products so far.
Because of the low barriers to entry, low technology content, large profits and wide market space, the yuba market has attracted many speculators, and the yuba market has become muddy, chaotic and full of fakes. According to statistics, there are more than 400 yuba production enterprises in China, not including a large number of OEM products and small workshops. Most of them are small factories in Zhejiang, and even some so-called "famous brands" are only produced by OEM in Zhejiang, and they often dare not indicate the place of origin. In order to occupy more market share, Yuba manufacturers mostly implement multi-brand strategy, and with unregistered brands and counterfeit products, there are nearly a thousand Yuba brands on the market. The price of Yuba has also dropped from more than 1,000 yuan at the beginning of listing to one or two hundred yuan.
But it should be noted that many "famous brands" are fakes! For example, Philips Yuba is actually produced by a small factory in Zhejiang registered by Philips Hong Kong Technology Company. Op is produced in Hong Kong, Shenzhen and other places (there are 6 or 7 producing areas, of course, only Hangzhou is authentic). A Yuba light bulb 15-20 yuan, a fan 25-30 yuan, the panel material cost 10 yuan, and the workers' salary is probably less than 150 yuan, so the market is in a chaotic state. The market bid is 200-300 yuan. Some inferior products actually just put light bulbs and fans together on a gorgeous panel.
Matters needing attention in the use of Yuba
1, Yuba power distribution system should be standardized. The maximum power of Yuba can reach more than 1 100 W, so the power cord for installing Yuba must be waterproof, preferably multi-wire copper core, with the height not less than1mm. All power cords must be embedded in the wall with plastic concealed pipes, and there must be no open wires. The power control switch of Yuba must be a qualified product with waterproof ability greater than 10A, especially.
Yuba should be installed in the center of the bathroom. Many families install it above the bathtub or shower, so the surface looks like it is heating up quickly in winter, but there are security risks. Because the infrared radiation lamp heats up quickly, it is easy to burn people if it is too close. The correct way is to install the Yuba in the center of the top of the bathroom or slightly near the bathtub, which is safer and can maximize its function.
3. Yuba is forbidden to spray with water when working. It will cause danger such as short circuit of power supply.
4. Avoid frequent switching and surrounding vibration. You can't switch the Yuba frequently at ordinary times. During the operation of Yuba, it is forbidden to have large vibration around it, otherwise it will affect the service life of the heating bubble.
