Description

Refrigerator {Refrigerator}

An embodiment of the present invention relates to a refrigerator.

The present invention relates to a refrigerator, and more particularly, to a refrigerator that provides a home-bar heater that can be separately controlled according to a temperature state inside and outside a home bar by improving the control structure of the home-bar heater provided in the home bar, and a control method thereof .

Generally, a refrigerator has a plurality of storage chambers for storing the foods to be frozen or refrigerated, and one side of the storage chamber is opened to receive and retrieve the food.

In recent years, a refrigerator is generally provided with a home bar on a part of the door so as to prevent the outflow of cool air more than necessary due to the opening and shielding of the door. Here, the home bar is a portion that can take out the beverage or food inside the refrigerator without opening the door of the refrigerator.

The refrigerator door is provided with an opening having a predetermined size in order to allow food to be stored or taken out through the home bar, and a home bar door for selectively blocking the opening is rotatably coupled to the opening.

On the other hand, the temperature difference between the inside and the outside of the refrigerator is large. That is, in the case of the refrigerating chamber, a temperature of about 2 to 3 ° C is formed inside the refrigerator, and an ambient temperature (about 15 to 25 ° C) of the environment where the refrigerator is installed is formed outside the refrigerator.

Therefore, a heat insulating material, which prevents heat transfer due to a temperature difference between the inside and the outside of the refrigerator, may be inserted into the inside of the home bar door.

In addition, the home bar may be provided with a home-bar heater to prevent moisture in the air from condensing around the home bar due to a temperature difference between the inside and the outside of the home bar.

On the other hand, the refrigerator door generally has a lower temperature than other positions of the opening due to a low insulation effect at the lower end of the opening, due to the installation structure of the home bar door.

In detail, the lower end of the opening portion is inserted with a smaller amount of the heat insulating material than other portions in order to secure a space in which the home bar door is rotated. Therefore, the cold air inside the refrigerator tends to be discharged to the outside through the lower end of the opening.

However, the conventional home-bar heater is arranged so as to be adjacent to the home-bar door along a certain portion of the refrigerator door and to supply the same amount of heat. Therefore, there is a problem that a low temperature phenomenon appears particularly at the lower end of the opening portion among the peripheral positions of the opening portion where the home bar door is installed.

Also, due to the difference between the temperature at the lower end of the opening and the ambient temperature of the refrigerator, moisture in the air is condensed at the lower end of the opening, and the condensed moisture is condensed in the refrigerator.

In this case, when the heat quantity of the home bar heater is increased to raise the temperature of the lower end portion of the opening, more power is required than the required electric power, resulting in an increase in cost due to electric power use. In addition, the temperature of the other portions of the opening, that is, the upper end portion and the both end portions, is also increased, and the refrigeration efficiency inside the refrigerator is deteriorated.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above problems, and it is an object of the present invention to provide a refrigerator in which the structure of a home bar heater provided in a home bar is improved to uniformly form a temperature around a home bar by a heater, .

In addition, a large number of heaters are disposed in the vicinity of a home-bar door at which a low temperature is formed, so that a uniform temperature is formed around the home-bar door and power consumption is reduced.

According to an aspect of the present invention, there is provided a refrigerator comprising: a main body having a cold storage room; a refrigerator door rotatably coupled to the main body and having an opening formed in at least a portion thereof; A home bar door to selectively shield the opening; And a heater provided in the refrigerator door to prevent condensation of the humidifier according to a temperature difference between the inside and outside of the home bar door. The heater is arranged such that at least one side of the opening is arranged to generate more heat than the other side .

According to another aspect of the present invention, there is provided a refrigerator including: a main body having a cold storage room; a refrigerator door rotatably coupled to the main body; And a home bar provided to the refrigerator door and having an opening for allowing food to be taken out, wherein the home bar is provided with a home bar door for selectively shielding the opening; A home bar frame in close contact with the home bar door when the home bar door is closed; And a heater provided inside the home bar frame to supply heat and arranged in multiple stages at one side of the home bar frame.

According to the present invention, it is possible to uniformly form the temperature around the home bar by arranging a heater having a large capacity at the lower end of the opening portion of the refrigerator door where the home bar door is installed, have.

Therefore, there is no need to increase the heating value of the heater as a whole in order to uniformly form the temperature around the home bar, thereby reducing the required power consumption.

In addition, a home-bar heater 102 for heating the refrigerator door around the opening 101 to prevent moisture from being condensed in the air due to a temperature difference between the inside and the outside of the refrigerator 120 are provided.

Hereinafter, the structure of the home-bar heater 120 will be described with reference to the drawings.

2 is a cross-sectional view taken along the line I-I 'of FIG.

Referring to FIG. 2, the home bar heater 120 according to the first embodiment of the present invention may be installed inside the home bar frame 102. A heat insulating material for inserting the inside and the outside of the refrigerator may be inserted into the inside of the home bar frame 102.

In detail, the home-bar heater 120 is disposed along the periphery of the opening 101. The home bar heater 120 is provided with an upper end portion 121 disposed on the upper side of the opening portion 101 and a lower end portion 121 extending from the upper end portion 121 and disposed on at least one side of the left and right sides of the opening portion 101 A lower end portion 123 extending from the first side end portion 122 and disposed below the opening portion 101 and a lower end portion 123 extending from the lower end portion 123, And a second side end portion 124 disposed on at least one side of the left and right sides.

Here, the second side end portion 124 may be disposed on the opposite side of the first side end portion 122 with respect to the opening portion 101.

In addition, the heaters may be arranged in one row in the upper end portion 121 and the side end portions 122, 124. On the other hand, at the lower end 123, the heaters may be arranged in a plurality of rows, that is, in multiple stages. That is, the lower end 123 may be arranged in a zigzag shape from the lower side to the lower side of the opening 101.

This is because the lower part of the home bar frame 102 has less heat insulating effect than the other parts. Specifically, the home bar door 103 is hinged to a lower portion of the home bar frame 102. A relatively small amount of heat insulating material is inserted into the lower portion of the home bar frame 102 to secure a space for rotating the home bar door 103.

Therefore, the cold air inside the refrigerator tends to flow out to the lower portion of the home bar frame 102, so that the lower portion of the home bar frame 102 is formed at a lower temperature than the other portions. As a result, there is a high possibility that moisture in the air is condensed and formed in the lower portion of the home bar frame 102.

In summary, the home bar heater 120 may be provided as a plurality of rows so that a large amount of heat is supplied to the lower portion of the home bar frame 102.

More specifically, a heater is arranged on the lower end portion 123 of the home-bar heater 120 to form a plurality of layers.

The lower end portion 123 is arranged in a jig-jagged shape in the horizontal direction. At least a part of the lower end portion 123 is formed with a plurality of bending portions 123a so that the heaters are arranged in a plurality of rows. The heaters may be spaced apart from each other by a predetermined distance.

As described above, since the heaters are arranged in a plurality of rows in the lower end 123, the amount of heat generated by the heaters is increased, and the degree of heating of the refrigerator door is increased accordingly. As a result, the lower portion of the home bar frame 102, at which a relatively low temperature is formed, can be raised to a temperature similar to other portions.

The number of rows of heaters arranged at the lower end 123 may be determined by comparing the difference between the lower temperature of the home bar frame 102 and the different temperature of the home bar frame 102.

One side of the lower end portion 123 is connected to one side of the first side end portion 122 and the other side of the lower end portion 123 is connected to one side of the second side end portion 124. That is, the side end portions 122 and 124 and the lower end portion 123 may be integrally formed.

Meanwhile, the home-bar heater 120 may be connected to a controller (not shown) for controlling the operation of the home-bar heater 120. Specifically, one side of the upper end 121 and one side of the second side end 124 may be connected to the controller.

Here, the home-bar heater 120 may be supplied with power by applying power to the refrigerator while powering the refrigerator.

Alternatively, the inside of the refrigerator may be provided with a temperature sensor for measuring the temperature inside the refrigerator. When the temperature measured by the temperature sensor is compared with the temperature outside the refrigerator, May be configured to operate.

Hereinafter, the structure of the home bar heater according to the second and third embodiments of the present invention will be described with reference to the drawings. However, the second and third embodiments differ from the first embodiment only in the shape and structure of the home-bar heater. Therefore, differences will be mainly described, and explanations and reference numerals of the first embodiment will be used for the same parts .

Here, the second side end portion 224 may be disposed on the opposite side of the first side end portion 222 with respect to the opening portion 101 as a center.

In the upper end 221 and the side ends 222 and 224, heaters may be arranged in one row. On the other hand, at the lower end 223, the heaters may be arranged in a plurality of rows. Therefore, a large amount of heat can be supplied to the lower portion of the home bar frame 102 by the heater, as compared with other portions.

More specifically, the lower end portion 223 of the home bar heater 220 includes a left portion 223a and a right portion 223b provided to be symmetrical with respect to the center of the lower end portion 223. The heaters arranged in the left and right portions 223a and 223b may be arranged at a predetermined distance from each other.

As described above, since the heaters are arranged in a plurality of rows in the lower end portion 223, the amount of heat generated by the heaters is increased and the degree of heating of the refrigerator door is increased accordingly. As a result, the lower portion of the home bar frame 102, at which a relatively low temperature is formed, can be raised to a temperature similar to other portions.

Here, the number of rows of heaters arranged at the lower end 223 may be determined by comparing the difference between the lower temperature of the home bar frame 102 and the different temperature of the home bar frame 102.

Meanwhile, the home bar heater 220 may be connected to a controller (not shown) for controlling the operation of the home bar heater 220. Specifically, one side of the upper end 221 and one side of the second side end 224 may be connected to the controller.
