The present invention relates to the deodorizing action of a refrigerator that removes various odors by using the oxidizing power of ozone (O ₃ ) and sterilizes low temperature bacteria, and in particular, by installing an auxiliary catalyst in the deodorizing device to prevent backflow of ozone (O ₃ ) and It relates to a deodorizer of the refrigerator to improve the deodorant effect by improving the fixed position and structure of the deodorizer device to be able to operate the cold air induction structure to induce cold air from the damper.

In the structure of a conventional refrigerator deodorizer as shown in FIG. 5, a square groove is formed in a portion of an inner portion of the refrigerator to attach the inner cover 31 to the rear, and foamed with urethane 32, followed by a separate forced circulation. The deodorizing cover 37 and the deodorizing support cover 38 are coupled to the front and rear of the support 36 to which the discharge electrode 34 and the ozone decomposition catalyst 35, etc., to which the fan 33 is connected, are attached. The integrated deodorizing device is configured to deodorize or sterilize odors and miscellaneous spores floating in cold air and cold air formed in the duct 41 by the fan motor 40 for cooling the refrigerator as shown in FIG. One side of the duct 41 is changed to use the cold air sent to the refrigerating chamber 42 along the passage so that the ozone generating electrode 43 and the high voltage generator 44 can be mounted, and a catalyst is provided at the lower end of the duct 41. As it was structure that we put on, refrigerator room (4 The refrigeration effect of 2) is lowered, and FIG. 5 shows that the cooling capacity is reduced due to the heat generation of the deodorizing motor 52 which is connected to the forced circulation 51 51 which forcibly sucks and circulates the cold air of the refrigerating compartment, thereby increasing power consumption. In addition, the noise increase factor as well as the complicated structure may cause ozone to leak during use. In FIG. 4, ozone decomposes at a low temperature by about 30%, and as a result, ozone flows into the refrigerating chamber 42 with increasing ozone. Also, when the temperature of the refrigerating compartment 42 reaches a predetermined temperature and the refrigerating compartment temperature control damper 46 is closed, the generated ozone (O ₃ ) is introduced into the freezing compartment 47 along the cold air passage while changing the direction. There was a flaw that occurred.

Accordingly, the present invention is devised to solve the conventional drawbacks and the construction and operation effects will be described in detail based on the accompanying drawings.

In the refrigerator 6 which introduces the cold air sucked from the evaporator 1 into the refrigerating chamber 5 as the duct A 2 and the fan motor 3 and the duct B 4, the cold air discharge port A 4a and the discharge port B. (4b), the duct B (4) provided with the discharge port C (4c) is placed on the back of the damper (7), and the auxiliary catalyst (9) and the ozone generating electrode into the case (8) at the cold air discharge port (A) The ozone generator 10 formed of the high voltage generator 10b and the main catalyst 11 are connected to each other to install the deodorizing device 12 in which the deodorized cold air flows into the refrigerating chamber 5.

Reference numeral 13 is k.

Referring to the effects of the present invention configured in this way in detail as follows.

Since food and other foods are stored in the refrigerator, odors may be generated and low-temperature miscellaneous spores floating in the air may penetrate the refrigerator. As shown in FIGS. 1 and 2, the refrigerator may be removed. (6) is used as a deodorizing device (12) installed in the refrigerator 6 when the power supply is applied to the refrigerator 6 with the door of the refrigerator 6 closed, the power is applied to the compressor fan motor (3) and high voltage generator (10b), etc. As the compressor, which is not shown, is operated to cool the evaporator 1, while the air sucked by the rotational force of the cooling circulation 13 connected to the motor 3 passes through the cooled evaporator 14, And the auxiliary catalyst 9 in the deodorizing device 12 installed in the discharge port A 4a of the duct B 4 through the temperature control damper 7 which controls the cold air passage formed in the duct A 2 according to the temperature. (7) High pressure generated when closed (10b) is to continue the work by generating ozone (O ₃₎ is reversed during the refrigerating compartment 5 is prevented from flowing in, and the high voltage generator (10b) is because the power is supplied ozone generator to generate a high voltage electrode (10a) As the ozone is generated, cold air mixed with odor and low temperature microorganisms present in the duct B (4) is discharge port A (4a), and one third of the air is ozone generating unit (10) through the auxiliary catalyst (9). ), While the deodorizing and low temperature microorganisms react with ozone in the main catalyst 11, the odor component is oxidatively decomposed, the low temperature microorganisms are sterilized and supplied to the refrigerating chamber 5, and 2 / Since 3 air flows into the discharge port B 4b and the discharge port C 4c without passing through the deodorizer 12, the cold air through the deodorizer 12 of the discharge port A 4a discharges the discharge port B 4b and the discharge port C. It appears 2 ~ 3 ℃ higher than the cold air introduced into the refrigerating chamber (5) directly through (4c), passing all the cold air to the deodorizing device (12) It does can be obtained, as well as sikilsu improve refrigeration efficiency of the refrigerator compartment (5), improvement in sikilsu remove the ozone that is countercurrent to laying the co-catalyst (9) in the deodorizing device 12 effects.
