Description

Refrigerator showcase with cold storage interior made of stainless steel plate {A refrigerator having an inner panel of a cool chamber made from a stainless steel}

The present invention relates to a refrigeration showcase equipped with a germicidal lamp, and more particularly, to the inside of the refrigerating compartment made of stainless steel so as to more effectively disperse the light (ultraviolet or ozone) emitted from the germicidal lamp and to exhibit the refrigeration effect more effectively. It relates to a refrigerated showcase formed.

Typically, the domestic refrigerator is largely composed of a freezer compartment and a refrigerating compartment, and the freezer compartment and the refrigerating compartment are opened and closed by respective doors provided at the front, respectively. The refrigerator is provided with a refrigerant circulation device and a rear duct and a recovery duct for cold air circulation at the rear or the bottom thereof. The refrigerant circulating device includes an evaporator (cooler), a compressor, a condenser, and the like.

In the refrigerator configured as described above, the saturated steam of the low boiling point refrigerant having the inside as the high heat source is compressed to a high pressure in a compressor and flows to the condenser, and the latent heat of evaporation from the high pressure and high temperature refrigerant is stored in the condenser. It is discharged to a high heat source outside the refrigerator to cause a phase change to a liquid refrigerant, and the liquid refrigerant is throttled to low pressure and low temperature while passing through an expansion valve, and then flows into an evaporator, that is, a cooler. In the cooler, the low-pressure, low-temperature refrigerant, mostly liquid phase, absorbs latent heat from a low heat source inside the refrigerator, changes phase into a saturated steam refrigerant, and then flows back into the compressor to form a circulation cycle of the refrigerant.

As described above, during repeated circulation cycles of the refrigerant, internal air contacts the cooler installed on the inside of the refrigerator and on the rear side to form cold air, which is supplied to the freezer compartment and the refrigerating chamber through the rear duct by a fan motor. The cold air supplied to the freezer compartment and the refrigerating compartment is recovered to the cooler side again through the recovery duct, thereby maintaining the temperature of the freezer compartment and the refrigerating compartment at a predetermined temperature.

In order to maintain the temperature of the freezer compartment and the refrigerating compartment at a predetermined temperature, an insulation is positioned between the walls of the freezer compartment and the refrigerating compartment as well as the airtightness of each door to prevent heat exchange between the freezer compartment and the refrigerating compartment.

On the other hand, when storing vegetables or perishable meat or fish in the refrigerator compartment, a sterilization lamp 20 such as an ultraviolet or ozone generating lamp is provided in the refrigerator compartment 40 as shown in FIG. It is provided at the top. The germicidal lamp 20 is turned off when the door 41 is opened by the power cut-off door switch connected to the door 41 of the refrigerator, and has a structure that is turned on when the door 41 is closed. The inner material 42 constituting the interior of the refrigerating compartment 40 in which the germicidal lamp 20 is installed is generally formed of a plastic injection molding, while the light (ultraviolet or ozone) of the germicidal lamp 20 is applied to the refrigerating compartment 40. Mainly white to reflect evenly inside.

In addition, the door 41 is provided as a transparent window so that the inside of the refrigerating compartment 40 can be seen from the outside.

However, as described above, the refrigerator having the internal material formed of the plastic injection molding has a low thermal dissipation effect because the sterilization effect is lowered because the light (ultraviolet or ozone) of the germicidal lamp is not evenly sprayed into the inside of the refrigerating chamber and is also formed of the plastic injection molding. There was a problem that the low refrigeration effect is low.

Accordingly, an object of the present invention is to provide a refrigerator or a showcase for refrigeration which can improve the refrigerating effect by increasing the reflection efficiency of the germicidal lamp so that the light (ultraviolet or ozone) is evenly reflected inside the refrigerating chamber and having a good thermal conductivity. It is.

As described above, in the cold storage showcase in which the germicidal lamp is installed in the refrigerating chamber for food storage, the inner material of the refrigerating chamber in which the sterilizing lamp is installed is formed of stainless steel whose outer surface is treated as a mirror surface. It can be achieved by the refrigeration showcase according to the present invention.

The refrigerating showcase according to the present invention is similar in structure to the refrigerating showcase shown in FIG. 1, but differs only in the material of the inner material forming the refrigerating compartment. Therefore, the present invention will be described with reference to the drawings showing the conventional refrigeration showcase shown in FIG.

In the showcase for refrigerating according to the present invention, the inner material 42 constituting the inside of the refrigerating chamber 40 is formed of a stainless steel sheet, the inner material 42 made of such a stainless steel sheet is a sterilization lamp (top) installed in the upper part of the refrigerating chamber 40 ( The outer surface is treated with a mirror surface so that the light (ultraviolet or ozone) emitted from 20 is evenly distributed to all areas of the refrigerating chamber 40, thereby effectively reflecting the light (ultraviolet or ozone) emitted from the germicidal lamp 20. .

Therefore, the light (ultraviolet or ozone) emitted from the germicidal lamp 20 is evenly sprayed from the inner material 42 treated with the mirror surface to each part of the refrigerating chamber 40, thereby sterilizing the food or the like stored in the refrigerating chamber 40. The effect can be improved.

In addition, since the inner material 40 is formed of a high thermal conductivity material such as a stainless steel plate, the freshness of the food, etc. stored in the refrigerating chamber 40 may be further contacted with the inner material 42.

According to the present invention, the inner material 42 constituting the interior of the refrigerating compartment 40 is formed of a stainless steel plate, whereby the shelf 43 provided in the middle of the refrigerating compartment 40 is emitted from the sterilization lamp 20 (ultraviolet rays). Or ozone) is preferably formed of a transparent material so as to be transmitted downward. Alternatively, the shelf 43 may have the form of a net so that light (ultraviolet or ozone) is transmitted downward.

In addition, the door 41 is provided as a transparent window so that the inside of the refrigerating compartment 40 can be seen from the outside, thereby enabling consumers to improve their purchase motivation when such a refrigerated showcase is used in a supermarket or a pharmacy.

According to the refrigerating showcase having a refrigerating chamber inner material made of stainless steel sheet according to the present invention, the refrigerating effect by increasing the reflection efficiency so that the light (ultraviolet or ozone) of the germicidal lamp is evenly reflected inside the refrigerating chamber, while having a good thermal conductivity Can improve.

As mentioned above, although the present invention is only referred to the refrigerating chamber of the refrigerating showcase, the same effect is also obtained when used in the refrigerating chamber or the freezing chamber of the refrigerator.
