Description

A clothes dryer equipped with a sterilizing and deodorizing device

technical field

The invention relates to the field of household appliances, in particular to a sterilizing and deodorizing device provided on a clothes dryer and a clothes dryer provided with the sterilizing and deodorizing device.

Background technique

With the progress of society, more and more people use clothes dryers, and people have higher and higher performance requirements for clothes dryers. For clothes that are not worn for a long time, because of long-term storage, bacteria, bugs, and odors in the environment will affect the clothes, which will cause bacteria to stick to the clothes and produce peculiar smells. Therefore, clothes that have been placed for a long time need to be cleaned before wearing. It performs simple treatment to sterilize and deodorize clothes, but ordinary washing and drying is time-consuming and laborious, and expensive clothes cannot be washed frequently, so clothes are simply treated with a clothes dryer or drying cabinet to achieve the purpose of sterilization and deodorization One point is particularly important.

Ultraviolet light is a fast and efficient physical sterilization method, which is widely used in medical, industrial and other fields. Ultraviolet rays can achieve the function of sterilization and disinfection, and sufficient irradiation intensity and dose must be guaranteed. This requires that the UV lamp has sufficient power. Under the current premise of energy saving and emission reduction, it is best if a low-power ultraviolet lamp can be used, but the low-power ultraviolet lamp cannot guarantee the intensity of sterilization.

The document with the notification number 201560328U discloses a washing/drying machine with bactericidal effect. In the document, an ultraviolet generating device and an ultraviolet output device are arranged in the box, and the ultraviolet rays generated by the ultraviolet generating device are transmitted to the ultraviolet output through the optical path. device, and the ultraviolet rays irradiated by the ultraviolet output device reach the area to be sterilized, without causing structural changes to the washer/dryer, and the installation is simple, but the shell or box of the current washer-dryer is made of plastic, and it takes a long time Light exposure will corrode the plastic and reduce the service life of the cabinet. If the box is corroded and cracked, ultraviolet rays will leak, causing certain damage to human skin and eyes.

Using ozone to sterilize is also a method. As we all know, although ozone has the function of sterilizing bacteria, but the concentration is too high, it will make people feel uncomfortable. Therefore, the clothes dryer needs to be sealed during the use of ozone, and the clothes after ozone treatment need to be post-treated. To make ozone emit, loaded down with trivial details and unsafe.

Titanium dioxide, the chemical formula is TiO2, is a snow-white powder, commonly known as titanium dioxide. Titanium dioxide has strong adhesion, is not easy to undergo chemical changes, and is non-toxic. It is widely used as a white pigment in paints. It has good hiding power, similar to lead white, but it does not turn black like lead white; it has the same persistence as zinc white. Titanium dioxide is also used as a matting agent for enamel, which produces a very bright, hard and acid-resistant enamel finish.

The TiO2 photocatalyst involved in the present invention is nano-TiO2, which has unique photocatalytic properties, excellent color effects, ultraviolet shielding and other functions, and has broad application prospects in photocatalysts, cosmetics, anti-ultraviolet absorbers and the like.
