Description

Drain Heater in Showcase

The present invention relates to a showcase for storing and displaying food and beverages at a low temperature, and more particularly, a showcase that prevents the drainage of water drained through the catch of the showcase from freezing due to the cold air in the store. It is about drainage heater of.

In general, the showcase is a device used to store and display food or beverages requiring refrigeration or freezing.

The showcase is based on the principle of freezing, and when a refrigerant by thermodynamic properties is moved into a closed circuit (refrigeration cycle) consisting of a compressor, a condenser, an evaporator, and vaporizes, it takes away heat from the surroundings and lowers the temperature to store food for a long time. To make it possible.

The showcase is basically a compressor for compressing the refrigerant into a gas of high temperature and high pressure, a condenser for liquefying the compressed refrigerant, an expansion valve for lowering the pressure of the high pressure refrigerant discharged from the condenser, and a refrigerant to vaporize the cold air. Evaporator for generating a, a cooling fan for dissipating heat from the condenser is operated by a fan drive motor, and a circulation fan driven by a circulation fan motor for forced circulation of the cold air generated from the cooler into the showcase It is done by

As shown, in the machine room 110 including the compressor 111, the condenser 112, the cooling fan 113 located below the main body of the showcase 100, and in the interior 102 of the showcase 100 The sump 103 which drains the generated water to the machine room 110 side is shown.

All devices using the cooling device including the showcase 100 are drained by the difference between the ambient temperature and the drainage during the driving of the cooling device. Is supported.

That is, the showcase 100 opens and closes the door 101 so that external hot air is introduced into the interior 102 of the showcase 100. Due to the temperature difference between the outside hot air and the low temperature air in the furnace 102, the cold air in the furnace 102 is condensed to generate droplets such as small dew.

These droplets flow down to the bottom surface of the interior 102 and are collected in the drain 103.

The drain pan 103 is configured to communicate with the machine room 110, the evaporation vessel 104 is installed at a predetermined position of the machine room 110 to contain the water drained through the drain pan 103.

That is, the drainage contained in the evaporation vessel 104 is made to evaporate naturally by the heat generated in the machine room (110).

However, the interior 102 of the showcase 100 is in a state of being lowered to about -26 ° C because the displayed goods should be kept at a low temperature.

Therefore, since the temperature of the inside of the furnace 102 becomes below the freezing point, the drainage water is frozen near the drain receiver 103.

That is, the drainage generated in the interior 102 will flow down to the bottom surface of the interior 102 and freeze near the drain pan 103.

Therefore, the drainage can no longer be drained through the sump 103, and since the drainage continuously accumulates around the sump 103, the bottom surface of the interior 102 is deformed. have.

The present invention was devised to solve the above-mentioned problems of the prior art, and the drain pan heater of the showcase which can promote smooth drainage by preventing the drainage drained through the drain pan of the showcase from freezing by the cold air in the refrigerator. The purpose is to provide.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

3 is a side cross-sectional view of a showcase to which an embodiment of the present invention is applied, and FIG. 4 is a plan view showing a drain heater according to an embodiment of the present invention.

As shown, a drain 6 for draining the waste water generated in the inside 2 of the showcase 1 to the evaporation vessel 7 formed on the machine room 3 side, and a machine room generating high temperature heat. Drain heater 10 is shown connected to the condenser 4 of (3) and inserted to surround the sump 6.

The showcase (1) is a condensation of cold air in the interior (2) by the temperature difference between the outside and the interior (2) to produce a drainage, which is contained in the evaporation vessel (7) located in the machine room (3) machine room It evaporates spontaneously by the heat of (3).

Since the showcase (1) has to preserve food and beverage for a long time, the temperature in the refrigerator (2) is lowered to a minimum of -26 ° C, so that the drainage freezes at the bottom of the storage (2) to block the drain hole (6 '). The phenomenon occurs.

That is, the drainage flows down the drainage wall 6 formed on the bottom surface of the in-vehicle 2 by riding on the wall surface of the in-house 2, and at this time, the drain-heater inserted in the vicinity of the drainage receiver 6. 10 dissipates the predetermined heat to prevent the drainage from freezing.

The drain receiving heater 10 is connected to one side of the condenser 4 for liquefying the refrigerant, and inserted into the surroundings of the drain collecting vessel 6, and the heat dissipated from the hot pipe 11 The heat dissipation panel 12 is prevented from being transferred to the inside 2 of the showcase 1.

Here, the condenser 4 serves to liquefy the refrigerant compressed by the gas of high temperature and high pressure in the compressor 5 located in the machine room 3 and emits heat of about 80 to 90 ° C.

Therefore, the hot pipe 11 of the drain receiving heater 10 connected to the condenser 4 may be a copper tube having excellent heat transfer efficiency.

In addition, the heat dissipation panel 12 is bolted to the bottom surface of the interior (2), it is bent and molded to shield the upper side of the drain (6).

The heat dissipation panel 12 is attached to the heat insulating material 13 having excellent heat insulating effect on one side, and is bent and formed so that the drainage can flow into the drain 6 to the side wall side of the inside of the refrigerator (2).

Drain heater of the showcase made as described above acts as follows.

The showcase 1 is a drainage is generated by the temperature difference between the interior (2) and the outside, the drainage flows down the side wall of the interior (2) to the side of the sump (6) formed on the bottom surface.

In addition, since the inside of the refrigerator 2 maintains a temperature below the freezing point for long-term storage of the displayed goods, the drainage freezes while flowing down to the drain receiver 6 side.

Here, a hot pipe 11 of the drain receiver 10 is inserted around the drain receiver 6, and the hot pipe 11 receives the heat generated from the condenser 4 and receives the drain receiver 6. Increases the ambient temperature.

In other words, the condenser 4 dissipates heat of about 80-90 ° C., thereby raising the ambient temperature of the sump 6 above the freezing point.

Therefore, since the drainage water is prevented from freezing around the drain receiver 6, the drainage water can be smoothly drained.

In addition, since the heat dissipation panel 12 is bent to allow the drainage to flow into the drain 6 to the side wall of the inside of the refrigerator 2, heat dissipated from the hot pipe 11 is transferred to the interior of the refrigerator 2. It can be minimized.

Therefore, the sump heater 10 can prevent the drainage from freezing around the sump 6.

As described above, the drain heater of the showcase of the present invention prevents the drainage generated due to the temperature difference between the inside and the outside air from freezing near the drain box, thereby preventing deformation on the bottom surface of the inside of the refrigerator, and at the same time, smooth drainage. It can be achieved, there is an advantage that can be realized by a simple structural change without the need of a separate power supply.
