Deodorant lamp for refrigerator

Abstract

The invention discloses a deodorant lamp for a refrigerator. The deodorant lamp comprises a substrate, wherein a driver and a controller for controlling the driver are arranged on the back surface of the substrate; a nanometer photocatalysis coating coats the front surface of the substrate; a plurality of UVA-LED package apparatuses, a group of stainless steel wires and a stainless steel net are also arranged on the front surface of the substrate in an integrating manner; the stainless steel wires and a stainless steel net are arranged in parallel; the driver is controlled to drive the UVA-LED package apparatuses and exert certain voltage between the stainless steel wires and the stainless steel net; and the UVA-LED package apparatuses send out ultraviolet lights to irradiate the photocatalysis coating and generate a catalysis substance, so that a harmful compound and a peculiar smell gas released from dead bacteria are decomposed; and degradation of organic matters is promoted, so as to reach a deodorization effect. Through the arrangement of the stainless steel wires and the stainless steel net, a high-voltage electrostatic field is formed when the deodorant lamp works; the deodorant lamp generates circulating airflow to work in a manner of driving plasma wind; degradation of the organic matters is accelerated; and the deodorization effect is improved.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting, in particular to a refrigerator deodorizing lamp. Background technique [0002] With the development of modern technology and the improvement of people's living standards, refrigerators have become an indispensable part of people's lives. At present, refrigerators on the market generally use low temperature to inhibit the growth of bacteria, so as to achieve the purpose of preserving food for a long time. But this method can not kill the bacteria, and the food will still spoil due to the growth of bacteria within a period of time. [0003] There are many technologies that can be used to eliminate bacteria in the air, such as chemical sterilization, ozone sterilization, traditional low-pressure mercury lamp ultraviolet light sterilization, etc. Chemical sterilization technology uses chemical reagents to sterilize, chemical reagents are easy to remain on the surface of objects, and...

Problems solved by technology

However, the use of low-pressure mercury lamps in the refrigerator has some disadvantages: first, the discharge substance mercury of the low-pressure mercury lamp is a heavy metal, which is very harmful to the human body if it is damaged and leaks, and it is not conducive to repair and maintenance after the glass lamp tube is damaged; the second is the switch The refrigerator door makes the low-pressure mercury lamp start frequently, shortening the life

The refrigerator described in this patent uses the generated ozone and negative ions to carry out sterilization and deodorization. The combination of the two improves the sterilization and deodorization effect of the refrigerator, but this method has the problem of residual ozone, and requires negative ion generators, ultraviolet lamps, etc. , micro-circulation fan, shading plate and other equipment, so that the deodorization device has many components and complex structure, which increases the manufacturing cost of the sterilization and deodorization device
