Abstract

PURPOSE: An air curtain device of a home bar room is provided to prevent inflow of exterior warm air the inner part of a home bar room when opening a door of the home bar room by preparing an air curtain device in the home bar room. CONSTITUTION: By the starting of a compressor(30), coolant is circulated by a cooling cycle and cool air is generated around an evaporator(10). By the rotation of a cooling fan(20), the cool air in the evaporator is sucked upward and blown into a cavity via a louver(50). The cool air is supplied via the gap between a cover(4) and a home bar box(2) from the storage chamber to keep the temperature of the food in a home bar room(E) proper. When opening a home bar door(3), an opening/closing switch(100) and a microcomputer senses the selection of a high speed refrigeration by a user. Power is fed to an air curtain motor(80) and an air curtain fan(90) is driven according to the driving of the air curtain motor. On driving of the air curtain fan, the cool air is blown downward from the front face of the home bar room. Thereby an air curtain is formed.

Description

Air curtain device in home bar room.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air curtain device of a home room, and more particularly, by providing an air curtain device in a home bar room of a side-by-side refrigerator in which a freezer compartment and a refrigerating compartment are separated on both sides, It relates to an air curtain device of the home bar room to prevent cold air leakage.

In general, a refrigerator is a home appliance used to freeze and refrigerate food by the heat of evaporation of a refrigerant using a cooling cycle. A refrigerator is used to freeze and refrigerate stored food by introducing cold air cooled by a cooler into a refrigerator. do.

A conventional refrigerator is roughly classified into a cabinet having a cavity having a predetermined volume in appearance and a door rotatably provided at a side of the cabinet to selectively open and close the cavity.

In addition, a rear of the cabinet is provided with a separate machine room for accommodating components such as a compressor, a condenser, and a capillary tube constituting the aforementioned cooling cycle.

The cooling cycle includes a compressor for compressing a gas refrigerant such as a freon into a gas refrigerant of high temperature and high pressure, and a condenser for cooling, condensing and liquefying gas refrigerant of high temperature and high pressure conveyed from the compressor by external air. And a capillary tube for depressurizing the liquid refrigerant from the condenser, and an evaporator for absorbing and cooling the surrounding heat while the depressurized refrigerant from the capillary is evaporated.

The air curtain device of the refrigerator is to prevent the outside air from entering the interior to prevent the temperature rise in the room according to the opening and closing of the door, such a conventional refrigerator air curtain device of the Republic of Korea Utility Model Publication No. 95-27331 For example.

In the conventional air curtain device of the refrigerator, as shown in FIG. 1, a cold air supply duct 11 of a predetermined space is formed inside the trimming plate 20 that separates the freezer compartment and the refrigerating compartment of the refrigerator. A blowing fan 12 is installed at the downstream end of the cold air supply duct 11, and the cold air injection slot 13, which is an outlet through which cold air is discharged at the end of the cold air supply duct 11, is opened downward in the horizontal direction downward. And a cold air suction opening 16a is upwardly opened in the corresponding refrigerator bottom plate 30 of the downwardly opened cold air injection slot 13.

In addition, a cold air suction fan 15 accommodated in the cold air suction port 16a and a cold air transfer duct 16 formed in the bottom plate 30 and communicated with the refrigerator machine room 40 are provided.

Unexplained reference numeral 10 denotes an evaporator of a refrigerator.

The air curtain device of the conventional refrigerator having such a structure has the following functions.

When the door is opened, the blower fan 12 is operated to suck the cold air of the evaporator 10 into the cold air supply duct 11, and the sucked cold air is discharged downward through the cold air injection slot 13. .

Subsequently, the cold air discharged vertically downward is sucked into the cold air suction port 16a by the cold air suction fan 15 which is operated at the same time as the operation of the blower fan 12 to the machine room 40 through the cold air transfer duct 17. Transferred.

Therefore, the cold air discharged vertically downward through the cold air injection slot 13 has a function of an air curtain to block the outside air introduced into the refrigerator as the door is opened.

On the other hand, some recent large refrigerators use a cooling cycle of the refrigerator to dispense cold water and ice to consumers, and a home bar room to easily take out frequently used drinks and foods. This equipped thing is proposed.

As shown in FIG. 2, the cabinet A is divided into a freezing compartment B and a refrigerating compartment C on both sides, and a dispenser for supplying water and ice to the front of the door of the freezing compartment B side ( D) is provided, the front door of the refrigerating compartment (C) side of the door has a structure that is equipped with a home bar (E) having a separate own door to easily take out frequently used drinks and food.

This dispenser (D) is provided with two operation levers to selectively supply water or ice, respectively, according to the user's intention. To provide ice, an automatic ice maker and a crushed ice are crushed and extracted according to a user's request. Ice extractor is required.

However, the home bar room of the conventional detachable refrigerator has a problem that it is difficult to maintain the temperature inside the home bar room at a constant temperature because warm air from outside air flows into the home bar room when the door is opened.

The present invention was created in view of the above-mentioned problems, and an object thereof is to provide an air curtain device in the home bar room to prevent external warm air from entering the home bar room when the door of the home bar room is opened. To provide the air curtain device of the home bar room.
