Problems solved by technology

However, food stored in the refrigerator, especially in the freezer for too long, can still cause spoilage
[0003] At first, in order to solve the problem of food preservation, people installed adsorption devices in refrigerators. The adsorption devices mainly used activated carbon to absorb the odor produced by microorganisms. However, activated carbon will become saturated and lose its adsorption performance after a certain period of use. It needs to be replaced in time. Inconvenient, at the same time, it does not have any effect on bacteria and mold on food, therefore, activated carbon has no antibacterial properties, and does not play a role in improving the preservation quality of food and extending the shelf life
Later, people added antibacterial agents to the liner of the refrigerator or some plastics, but it can only kill the bacteria on the surface. It is a contact sterilization, and it cannot decompose the bacteria and harmful components in the air.
In addition, people also use ozone generated by an ozone generator in the refrigerator to kill bacteria, but the ozone smell is heavy, which is not only harmful to the human body, but also has a strong oxidation effect on food, which will oxidize the food in the refrigerator compartment. , lose the fresh-keeping function, and also cannot guarantee the high preservation quality and long shelf life of food

Embodiment 1

[0024] This embodiment provides a deodorizer for a refrigerator, such as figure 1 and figure 2 As shown, the deodorizer for a refrigerator includes a deodorizer body 1. The deodorizer body 1 in this embodiment is a square polyester non-woven fabric block, and the deodorizer body 1 has a porous network structure. A deodorant layer 3 is bonded to the outside of the deodorant body 1 through an adhesive layer 2 . Adhesive layer 2 selects acrylic resin as adhesive. The deodorant layer 3 is a mixture of nano-titanium dioxide, apatite, nano-platinum and ceramic materials. The polyester material of the polyester non-woven fabric block, the resin material of the adhesive layer 2 and the weight percentages of the components of the deodorant layer 3 are: polyester non-woven fabric 85.6%, acrylic resin 5.7%, nano-titanium dioxide 5.5% , 2.4% apatite, 0.2% nano-platinum, and 0.6% ceramic material.

[0025] Among them, the porous network structure of the polyester non-woven block can n...

Embodiment 2

[0034] This embodiment provides a refrigerator, such as image 3 As shown, the refrigerator includes a refrigerator deodorizer 5 and a light source 4 as described in Embodiment 1. The deodorizer 5 is installed in each room of the refrigerator or in each air duct opening, and the light source 4 is an ultraviolet light source or a blue LED lamp. The distance H between the light source 4 and the deodorizer 5 is 40 mm.

[0035] Under the irradiation of external ultraviolet light or LED lamp, the titanium dioxide in the deodorizer can absorb the light energy to generate electron leap and hole leap, and further combine to generate electron-hole pairs, which react with water and oxygen in the air or food Generate very active oxidizing hydroxyl radicals and superoxide ion radicals, which can reduce organic and inorganic substances contained in food to carbon dioxide, water and other non-toxic and harmless substances under the action of photocatalytic oxidation. The gas molecules are ...

Abstract

The invention discloses a deodorizer for a refrigerator and a refrigerator, which belong to the technical field of refrigerators and are designed to solve the problems that the existing refrigerators cannot efficiently, permanently and thoroughly sterilize, deodorize and keep fresh, and have low safety. The deodorizer for the refrigerator includes a deodorizer body, the deodorizer body has a porous network structure, and a deodorant layer is coated on the outside of the deodorizer body. There is also proposed a refrigerator including the above-mentioned deodorizer for a refrigerator and a light source. The porous network structure of the deodorizer body in the present invention can not only filter the solid impurities in the air, but also absorb the water in the air, effectively balance the moisture of the food and keep the freshness, so that the preserved food is not easy to breed bacteria and mold; The deodorant layer coated on the outside of the deodorizer body can efficiently, permanently and thoroughly sterilize and deodorize, with a deodorization rate of over 95%, good fresh-keeping effect, harmless to the human body, and high safety.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a deodorizer for a refrigerator and a refrigerator with the deodorizer. Background technique [0002] The refrigerator can be used to preserve food, store fruits and vegetables, fresh food, etc. However, food stored in the refrigerator, especially in the freezer, can still cause rot if left for too long. [0003] At first, in order to solve the problem of food preservation, people installed adsorption devices in refrigerators. The adsorption devices mainly used activated carbon to absorb the odor produced by microorganisms. However, activated carbon will become saturated and lose its adsorption performance after a certain period of use. It needs to be replaced in time. It is inconvenient and does not have any effect on bacteria and mold on food. Therefore, activated carbon has no antibacterial properties and has no effect on improving the quality of food preservation and e...
