First, infrared damage the eyes and skin
Infrared is a form of thermal radiation that can cause high temperature damage to the human body. Stronger infrared rays can cause skin damage, similar to scald. It was initially burning and then burned. There are several different situations where infrared radiation damages the eyes. Infrared rays with a wavelength of 0.75 to 1.3 microns have a high transmittance to the cornea, which can cause damage to the retina of the fundus. Especially in the vicinity of 1.1 microns of infrared, can make the front of the eye media (cornea, crystal, etc.) is not damaged directly caused by retinal burns. Infrared rays with a wavelength of more than 1.9 microns are absorbed almost entirely by the cornea, causing corneal burns (turbidity, white spots). Most of the energy of infrared rays with a wavelength greater than 1.4 microns is absorbed by the cornea and the inner fluid, and it does not penetrate the iris. Only 1.3 micron infrared can penetrate the iris, causing iris damage. The human eye can cause cataracts if exposed to infrared rays for a long period of time.

Diagnostic Criteria of Occupational Cataract

A.1 Occupational cataracts The main causes of cataract are chemical and physical factors. The common clinical manifestations are the degree of opacity of the eye lens at different levels, different parts and different forms. The common clinical types and major causes of occupational cataract are as follows: String 7
a. Toxic cataract, see Appendix C (normative);
b. Non-ionizing radiation cataracts, mainly microwave cataracts, infrared cataracts and UV cataracts. Microwave cataract refers to the damage of intraocular lens caused by radiation in the frequency range of 300MHz-30OGHz in the electromagnetic wave or 1m-1mm: wavelength; infrared cataract is the heat radiation in the high temperature operating environment, ie, the wavelength is shorter than 3x1O-6m, ie, the lens is shorter than the infrared radiation. Damage; Exposure to UV light can also cause cataracts;
Of course, the protective method is to make your eyes not be in direct contact with the infrared front, or sit on its side, look out of place, or simply face it, get warm and avoid its harm, infants and young children take a shower. In the basin, looking upwards, if there is a bath fighter on the top, this child's eyes may already be over, parents and children will suffer from it in the future, do not let the baby at home when the baby has to take a bath Turn on Yuba while the child is facing up, otherwise it will cause permanent damage to the child's future vision.
Second, the glare is very easy to burn the eyes China Medical University Shengjing Hospital Eye Professor Guo Yuzhen introduction, family bathroom generally rely on bath heaters to warm, when people take a bath in winter, it is often all four light bulbs lit. The majority of Yuba’s bulbs each have a wattage of 275 watts, and 4 bulbs add up to 1100 watts. Strong light can cause light pollution. If you regularly use Yuba for a long time, you will experience dizziness, insomnia, inability to concentrate, and loss of appetite. This is because too dazzling light interferes with the central nervous system function of the human brain. There is also data showing that light pollution will impair the visual function of infants and children, affecting children's vision development.
Third, the bathroom is not waterproof
Although Yuba waterproof bulbs have waterproof performance, but the lamps and exhaust fans, lighting and other non-IP33 waterproof structure lights, but the metal parts of the body is not waterproof, that is, the body of metal is still conductive, if the water is poured, it will Causes a power short circuit and other hazards.
Fourth, the bathroom is not comfortable
The operating principle of Yuba is to raise the temperature of the bathroom by the heat radiation of the heating bulb. However, only the local area irradiated can be heated, and the entire bathroom cannot be warmed. The bathroom temperature is not balanced. The warm heating of the Yuba does not meet the comfort requirements of the human body's feet and head cold, and it is easy for the elderly and children and the weak to cause respiratory infections. This is why people who have used Yuba do not feel warm and comfortable.
Fifth, the quality of bathroom heaters is uneven, counterfeit and shoddy, and the purchase should be cautious.
AQSIQ announced the survey data, sampling inspection of indoor heater products (including Yuba), nearly 40% of products failed. The results of spot checks in Shanxi, Sichuan, and other provinces showed that the passing rate of Yuba was only about 50%. As a product with Chinese characteristics (without such products abroad), it has been in the market for more than ten years. To date, the country has not introduced an industrial standard for Yuba products. Because of the low barriers to entry in the production of Yuba, low technical content, large profits, and wide market space, it attracted many speculators, and the Yuba market became muddled, chaotic, and counterfeit. According to statistics, there are more than 400 bath manufacturers in China, not including a large number of OEM products and small workshops. Most of them are small factories in Zhejiang Province. Even though some so-called "brand names" are just OEMs in Zhejiang, they often do not dare to indicate their place of production. Yuba manufacturers mostly accounted for market share and mostly implemented a multi-brand strategy. In addition to unregistered brands and counterfeit products, the Yuba brand on the market was nearly a thousand. The price of Yuba also dropped from one thousand yuan to RMB one or two hundred yuan at the beginning of listing. However, it should be noted that many "brand names" are fakes! For example, philips Yuba is actually a small factory in Zhejiang registered in Hong Kong with a Philips Hong Kong technology company. Aupu Yuba has production in Hong Kong, Shenzhen and other places (there are 6, 7 places of origin, of course, only Hangzhou is authentic). One Yuba bulb 15-20 yuan, fan 25-30 yuan, panel materials costs 10 yuan, plus workers' wages are probably less than 150 yuan, the market is chaotic, in a state of basic disorder. The market is priced 200--300 yuan. Some inferior products actually only put light bulbs and fans together on a gorgeous panel.
The use of Yuba Note 1, Yuba power wiring system to be standardized. Yuba power up to 1100W or more, therefore, the installation of Yuba power wiring must be waterproof, it is best not to dry 1mm multi-wire copper wire, all power wiring must take the plastic pipe inlaid in the wall There must be no open-wire setting. The Yuba power control switch must be a qualified product with a waterproof capacity of more than 10A. In particular, the old bathroom installation bathroom should pay attention to specifications.
2, Yuba should be installed in the center of the bathroom. Many families install it above the bathtub or shower, so that the surface seems to be warming up quickly in the winter but there are security risks. Because infrared radiation lamps warm up quickly, it is easy to burn the body. The correct method should be to install the bathroom heater in the center of the bathroom top, or slightly close to the bathtub, so that it is safe and can maximize the function. 3, prohibit the use of water spray at work bath. This may cause a danger such as a short circuit to the power supply. 4, avoid frequent switching and vibration around. Usually do not use the switch frequently Yuba, Yuba operation should not be surrounded by a larger vibration, otherwise it will affect the life of heating foam. 5, heating lamps and Yuba can not be used at the same time
