Moreover, the purpose is to prevent deformation of the air passage due to abnormal operation of the heating element. [Structure] Adsorption type deodorizing material 4 on the back surface of L-shaped waterproof cover 3
Is attached by a net 5 to form a waterproof cover.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  According to the present invention, water is directly exposed to the heating element of the defroster of a refrigerator equipped with a deodorizer. For waterproof cover to prevent.

[0002]

[Prior art]

  A conventional waterproof cover for the heating element that is provided at the bottom of the evaporator. The shape of the odorant is that the cold air that circulates inside the refrigerator is It had a plate-like shape that covered the upper part so that it could easily pass through the frosted part. Prevents the intake water from splashing on the adsorption-type deodorizing material and affecting the performance of the adsorption-type deodorizing material. It also played a role.

[0003]

[Problems to be solved by the device]

  However, in the above configuration, due to fluctuations in the power supply voltage, defective defrosting function, etc. When the heating element abnormally generates heat, the air passage through which cold air passes may be deformed due to the heat. Had problems. On the other hand, equipped with a heat shield to reduce the influence of heat on the air passage If so, there is a problem that the deodorizing effect is significantly reduced.

[0004]   The present invention solves the above-mentioned problems and is caused by abnormal operation of the defrosting heating element. Preventing deformation of the air passage for cold air circulation to improve safety and ensure both deodorizing effect of adsorption type deodorizing material The purpose is to provide a realized refrigerator.

[0005]

[Means for Solving the Problems]

  The first means of the present invention for achieving the above-mentioned object is to make the waterproof cover substantially L-shaped. That is, it is configured to cover the upper surface and the front surface of the heating element.

[0006]   Also, as a second means, a slit for air circulation is provided on the front surface of the L-shaped waterproof cover. Provided.

[0007]   Furthermore, as a third means, an adsorption type deodorizing material is provided on the back of the bent portion of the L-shaped waterproof cover. It was provided on the surface.

[0008]

[Action]

  In the refrigerator according to the present invention, the heating element is overheated during defrosting by the first means. In the event of heat, the heat is blocked by the L-shaped prevention cover, and the temperature of the material forming the air passage increases. do not do.

[0009]   Also, by the second means, the air can pass through the slit of the L-shaped waterproof cover well. However, it does not hinder ventilation.

[0010]   Further, by the third means, the air passing through the slit of the L-shaped cover is good. Touch the adsorption type deodorant material.

[0011]   In addition, the L-shaped waterproof cover allows the defrosting water to be a defrosting heating element and an adsorption type deodorizing material. I can hang on.

[0012]

【Example】

  An embodiment of the present invention will be described below with reference to FIGS.

[0013]   In the figure, 1 is an evaporator of a refrigerator, 2 is a fan motor for circulating cold air, and 3 is an L-shape. Type waterproof cover 4 is an adsorption type deodorant and is held on the L-shaped waterproof cover 3 by a net 5. Has been. Reference numeral 6 is an air passage, and the cold air that has undergone heat exchange in the evaporator 1 is a fan mode for circulating cold air. The food storage room 7 is circulated by the tar 2 and the adsorption type deodorizing material 4 is installed through the air passage 6. After passing through the place, it returns to the storage part of the evaporator 1 again.

[0014]   The flow of the circulation of the cold air is shown by an arrow, but when the cold air touches the adsorption type deodorizing material 4, The odorous components carried from the food storage room are adsorbed by the adsorptive deodorizing material 4. Cold wind Touch the adsorption type deodorizing material 4 on the back surface of the L-shaped waterproof cover 3. And L-shaped waterproof cover The structure is such that the adsorption-type deodorizing material 4 is contacted via the slit 8 of No. 3. Next First, the effect of the heating element 9 on the air passage during defrosting will be described. Radiation from the heating element 9 Although the heat of radiation raises the surface temperature of the material forming the air passage 6, the L-shaped waterproof cover 3 is used. Since the heat is shielded, the surface temperature of the forming material of the air passage 6 can be prevented from rising. or , The air satisfactorily flows through the slit 8 provided on the front surface of the L-shaped waterproof cover 3 and , Touch a large amount of adsorption type deodorant.

[0015]

[Effect of device]

  As described above, the present invention includes the waterproof cover provided at the bottom of the evaporator, -For a refrigerator with a suction deodorant attached to the back side, L-shaped waterproof cover By making it a mold and providing slits in the L-shaped waterproof cover, L-shaped waterproof The cover circulated in the food storage room while the air flowed well without resistance to ventilation. Since the cold air is in contact with the adsorption type deodorizing material more, the deodorizing effect can be improved. In addition, the radiant heat when the temperature of the heating element rises abnormally causes the thermal deformation of the airway surface material to be L-shaped. It is safe and can be prevented by the effect of the heat shield plate of the waterproof cover, and has good deodorizing effect and heat efficiency It is possible to realize a refrigerator.
