Description

Refrigeration sterilization and deodorizer

The present invention relates to a sterilization and deodorization device of the refrigerator, and more particularly, to a sterilization and deodorization device of a refrigerator which can maximize the sterilization and deodorization function by allowing the cold air of a special room to directly enter the sterilization deodorization device.

In general, the refrigerator is to store various foods in the refrigerated and frozen state to maintain the freshness for a long time, and the freezer compartment and the refrigerating compartment are divided into upper and lower sides by the middle wall, and the cooling fan and the evaporator are disposed on the rear wall of the freezer compartment. It is forcibly circulating the air in each refrigerator to continuously exchange heat with the evaporator to keep various foods fresh.

However, such a conventional refrigerator contains odors and airborne bacteria that have been stored for a long time in the cold air, thereby circulating the inside of each refrigerator, so when the door is opened for storing and withdrawing food, the odor is discharged to the outside, causing discomfort to the user. As well as giving a floating bacteria was a problem that is unsanitary to breed in stored food.

In order to solve this problem, recently, a sterilization deodorizer has been installed at a predetermined position in the refrigerating chamber to deodorize and sterilize odors and floating bacteria contained in cold air.

A sterilization deodorization apparatus installed to remove odors and floating bacteria as described above will be described in more detail with reference to FIG. 1.

The sterilization deodorizing device 50 has an outer body 51 through which an inlet 511 is formed at a lower portion thereof and an outlet 512 is formed at one side thereof, and an ultraviolet lamp 52 and a catalyst member (inside the outer body 51). 53 is installed in communication, and the fan motor 54 is mounted inside the outlet 512.

The conventional sterilization and deodorization apparatus of the refrigerator configured as described above is complicated in structure and manufacturing cost by being configured to perform deodorization and sterilization while inhaling and discharging cold air circulating in the refrigerating chamber to forced air using the fan motor 54. In addition to the increase in airflow, the fan motor is not able to accommodate the whole cold air circulating in each of the relatively high air flow capacity, and in particular, the airborne bacteria and odor contained in the cold air circulating the special compartment partitioned in the refrigerator compartment cannot be sterilized and deodorized. There was a problem.

As an apparatus for sterilizing and deodorizing a refrigerator which has solved such a problem, there is a Japanese Patent Application Laid-Open No. Hei 1-159579 filed in Japan on December 16, 1987 and published on June 22, 1989.
