Description
Technical Field
The invention relates to the technical field of refrigerators, in particular to an air-cooled refrigerator.
Background
Refrigerators have been widely used as electric appliances providing a low temperature environment to extend the storage time of articles, but, during the use of the refrigerators, unpleasant odors are generated in the refrigerators due to biochemical effects such as oxidative decomposition of foods stored in the refrigerators and contaminants attached thereto.
The peculiar smell problem and the microbial contamination in the refrigerator are two important factors influencing the use of users all the time, most of the traditional refrigerators oxidize peculiar smell gas or kill microorganisms through high-energy ion groups such as plasma, negative ions and the like generated by high-voltage discharge, and because the scheme has longer effect acting time and is accompanied with the generation of ozone, the refrigerator has certain influence on the human health and the inner container of the refrigerator.
Disclosure of Invention
One object of the present invention is to provide an air-cooled refrigerator with a sterilization and deodorization module.
It is a further object of the present invention to protect the location of the sterilization and odor elimination module so that the sterilization and odor elimination efficiency is higher.
In particular, the present invention provides an air-cooled refrigerator comprising:
a case defining a storage space;
the air duct assembly is arranged at the back of the storage space, is detachably connected with the box body, and is internally provided with an air duct for supplying refrigerating airflow to the storage space;
and the at least one sterilization and odor removal module is arranged in the air duct and is used for sterilizing and odor removing the refrigerating air flow flowing to the storage space.
Optionally, the air duct comprises at least one first air duct for supplying air to the upper part of the storage space;
the sterilizing and deodorizing module is arranged in the first air duct.
Optionally, the first air duct has two first air outlets, and is disposed at two sides of the upper portion of the storage space, so that the refrigerating airflow flows to two sides of the storage space;
the sterilizing and deodorizing module is arranged between the two first air outlets.
Optionally, the lower part of the storage space is provided with an air return opening;
the sterilization and deodorization module is arranged at the air return opening.
Optionally, the air duct assembly comprises:
the air channel main body is arranged at the back of the storage space and is provided with an air channel for supplying refrigerating airflow to the storage space;
the air duct cover plate is covered on one side of the air duct main body facing the storage space to cover the air duct.
Optionally, at least one first fixing piece is arranged at the edge of the air duct cover plate;
the air duct main body is provided with a first fixing groove at a position opposite to the first fixing piece, so that the air duct cover plate and the air duct main body are detachably connected through the matching of the first fixing piece and the first fixing groove.
Optionally, a fixing frame is arranged on one side of the air duct cover plate facing the air duct main body, and the sterilization and deodorization module is arranged in the fixing frame;
a through hole is formed in the position, opposite to the fixed frame, of the air duct main body; the air duct cover plate covers the air duct main body, and the fixing frame provided with the sterilization and odor removal module can pass through the through hole, so that the sterilization and odor removal module can sterilize and remove odor of the refrigerating air flow flowing to the storage space.
Optionally, the sterilization and odor removal module is prepared on the basis of an adsorption material; wherein,
the adsorption material comprises at least one of activated carbon, molecular sieve and silica gel.
Optionally, the sterilization and odor removal module is prepared based on bioactive materials; wherein,
the bioactive material comprises beneficial bacteria such as Bacillus bifidus and lactobacillus, and at least one of garlic essential oil, mustard essential oil, lemon essential oil, and eucalyptus oil.
Optionally, the sterilization and odor removal module is prepared based on a chemical catalytic material; wherein,
the chemical catalytic material comprises at least one of antiseptic, antibiotic and lysozyme.
According to the air-cooled refrigerator provided by the embodiment of the invention, the sterilization and odor removal module is independently arranged on the detachable air channel assembly, so that the air channel assembly can be replaced in time or the sterilization and odor removal module on the air channel assembly can be replaced when the module efficiency on the air channel is reduced, and the sterilization and odor removal module can be always kept in high-efficiency operation in the refrigerator by arranging the sterilization and odor removal module at the air outlet or the air return port of the air channel; on the other hand, the secondary pollution and the peculiar smell caused by the growth of bacteria and mildew due to the overlong use time of foam or other components in the air duct can be prevented.
The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

The adsorbing material in this embodiment is a material with a large specific surface area, such as activated carbon, molecular sieve, silica gel, and the like. They tend to have a strong adsorption of odorous gases. Therefore, the material can adsorb most of peculiar smell gas and microorganisms in part of air of the refrigerator, thereby playing roles in purifying the air of the refrigerator and removing harmful microorganisms.
In addition, the sterilization and odor removal module 400 prepared based on the adsorption material has the greatest characteristic of rapidly and efficiently removing odor in the refrigerator. The electronic sniffing instrument is used for testing the odor removing effect of the pickled vegetables in the refrigerator, the test result is shown in fig. 9, the abscissa in the odor component spectrogram of the refrigerator in fig. 9 is time (unit is min), and the ordinate is the odor content, and analysis shows that the odor removing efficiency of the sterilization and odor removing module 400 in the first 10 minutes is very high, and the odor removing effect approaches to be stable after ten minutes. In order to increase the specific adsorption to the peculiar smell molecules and the killing effect to microorganisms, nano silver ions can be added into the material, so that the module has the sterilization and antibacterial properties.
Secondly, the sterilization and odor removal module 400 is prepared based on bioactive materials;
the sterilization and odor removal module 400 prepared from bioactive materials refers to a module which is realized by taking substances with bioactive functions as bases as active ingredients, such as beneficial bacteria such as bifidobacteria and lactic acid bacteria, and extracts of plant active ingredients such as garlic essential oil, mustard essential oil, lemon essential oil and eucalyptus oil, such as eucalyptus oil, wherein the main ingredients of the module are 1, 8-cineole (more than 80%), camphene, phellandrene, terpineol, geraniol acetate, isovaleraldehyde, citronellal, piperitone and the like, and the module can be widely used for treating cold, influenza, dysentery, enteritis, arthralgia, cystitis, scald, mange, erysipelas, neurogenic dermatitis, eczema and carbuncle sore pyogenic infections. Therefore, they spread to the corners of the refrigerator compartment along with the wind circulation, and their own biological activities can act to kill microorganisms and remove odor gas.
Deodorizing mechanism of plant essence extract

Hydrogen sulfide generated in practical use can be removed by the 1) mechanism.
In the experiment, in a 60L test space, under the environment of 5 ℃, the initial concentration of the odor is 10ppm, and the removal rate of 30min and 60min is tested as the test condition, and the test result is shown in the table 1.
