A refrigerator

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a refrigerator including a highly efficient heat insulating portion located in a lower portion of a receiving portion formed in a partition wall located between a refrigerating chamber and a freezing chamber.

The refrigerator generally includes a refrigerator and a freezer. Foods to be stored at the image temperature are stored in the refrigerator compartment, and foods that should be stored at a subzero temperature are stored in the freezer compartment.

Accordingly, the temperature inside the freezing compartment is different from the temperature inside the freezing compartment, so that a partition wall including a heat insulating part for heat insulation is positioned between the freezing compartment and the freezing compartment.

In recent years, an attempt has been made to make a storage space recessed in the partition wall to increase the storage capacity of the refrigerator.

However, in this case, the thickness of the partition wall and the heat insulating portion is reduced, resulting in insufficient heat insulation between the freezing compartment and the freezing compartment.

As a result, there is a problem that dew is generated in the refrigerating chamber and the power consumption of the refrigerator is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator having improved insulation efficiency at a portion of a heat insulating portion which is relatively thinned by a receiving portion formed in a partition wall.

According to an aspect of the present invention, there is provided a refrigerator comprising: a refrigerating chamber having a temperature of an image; A freezing chamber having a sub-zero temperature; A compartment positioned between the refrigerating compartment and the freezing compartment and having a first heat insulating part; A receiving portion located inside the partition and capable of storing food; And a second heat insulating part provided between the accommodating part and the refrigerating compartment or between the compartment and the freezing compartment.

In addition, it is preferable that the second adiabatic portion is disposed between the outer surface of the partition portion and the storage portion.

Preferably, the refrigerating compartment is located at an upper portion of the refrigerator, the freezing compartment is located at a lower portion of the refrigerator, and the compartment is recessed downward from an upper surface of the partition wall forming the bottom of the refrigerating compartment.

It is preferable that the second adiabatic portion is disposed between the lower surface of the partition portion and the storage portion.

In addition, it is preferable that the compartment wall forming the bottom of the refrigerating compartment is provided with a compartment door capable of opening and closing the compartment in a sliding manner.

The first heat insulating part may include a heat insulating material including a plurality of pores, and the second heat insulating part may include a vacuum insulating material in which the plurality of pores are in a vacuum state.

The second adiabatic portion may include a heater for generating heat.

The controller may further include a controller for controlling the temperature of the heater according to a temperature difference between the storage compartment and the refrigerating compartment or a difference between the storage compartment and the freezing compartment.

Further, it is preferable that the refrigerator further comprises a door positioned in front of the refrigerating chamber and the freezing chamber, and the receiving portion is disposed in front of the partition.

Further, the refrigerator includes a refrigerator door for opening and closing the refrigerator compartment, and a door basket protruding toward the refrigerator compartment is formed on the inner side of the refrigerator compartment door, And the storage compartment door is located below the door basket when the refrigerator compartment door is in a closed state.

Further, it is preferable that a vegetable box in the form of a rectangular parallelepiped having an open top is provided at the rear of the door basket.

Preferably, the storage unit is an egg storage unit, and the temperature of the image is maintained by interrupting the cool air from the freezing chamber of the second heat insulating unit inside the egg storage unit.

As described above, the heat insulating performance of the partition wall is normalized to prevent the occurrence of dew in the refrigerating chamber and the receiving portion.

1st Example

Hereinafter, a structure of a refrigerator according to a first embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2, the refrigerator according to the first embodiment of the present invention includes a refrigerator compartment 100, a freezer compartment 200, a partition wall 300, a storage compartment 400, and a vacuum insulation material 500, . ≪ / RTI >

As an example, the refrigerating chamber 100 may be located at an upper portion of the refrigerator, and the freezing chamber 200 may be located at a lower portion of the refrigerator, but the present invention is not limited thereto. When the refrigerating chamber 100 is located at the upper portion of the freezing chamber 200, there is an advantage that the user does not have to bend the body when the food is inserted into or taken out from the refrigerating chamber 100, which is relatively frequently used.

The refrigerating compartment 100 maintains the temperature of the image and stores the food to be stored at the temperature of the image.

The temperature of the refrigerating compartment 100 may be changed as the user operates the refrigerator compartment temperature control lever (not shown), and may be operated at a subzero temperature according to the user's operation.

The refrigerator compartment 100 may include a refrigerator compartment door 110 and a plurality of shelves 120.

The refrigerator compartment door 110 is rotatably attached to the front surface of the refrigerating compartment 100 to selectively open and close the refrigerating compartment 100.

The refrigerator compartment door 110 includes a door basket 111 as an example.

The door basket 111 protrudes from the refrigerator compartment door 110 toward the refrigerating compartment, i.e., rearward. The door basket 111 extends to the front of the vegetable box 121, which will be described later, as shown in Fig. Preferably, the door basket 111 has a width and a width such that a water bottle, a beverage bottle containing a capacity of 1.5 L or more, and the like can be accommodated.

As will be described later, it is preferable that the storage compartment 400 is positioned below the door basket 111.

A plurality of shelves 120 may be provided in the refrigerating chamber 100. The number of shelves 120 may be four, for example, but not limited to, as shown in FIG. 2, and the shelves 120 may be selectively separated from the refrigerating chamber 100 by a user. The shelf 120 functions to divide the entire space of the relatively large refrigerating compartment 100, and food or the like can be stored on the shelf 120.

Preferably, the vegetable box 121 is positioned below the shelf 120 located at the bottom of the refrigerating compartment 100.

The vegetable box 121 may be in the shape of a rectangular parallelepiped having an open top, but is not limited thereto. However, it is preferable that the vegetable box 121 is a case having a sidewall extending upward to prevent the vegetable from being poured therein.

The vegetable box 121 is slid forward and the vegetable box 121 is in a state capable of storing vegetable products such as vegetables. When the vegetable box or the like is housed and then pushed rearward, the opened upper portion of the vegetable box 121 is slid rearward so as to be completely covered by the shelf 120 located at the bottom of the refrigerating chamber 100.

The freezing chamber 200 maintains the temperature of the subzero, and the food to be stored at a subzero temperature is stored and stored.

The temperature of the freezing room 200 may be changed as the user operates the freezing room temperature control lever (not shown), and may be manipulated to the temperature of the image according to the user's operation.

The freezer compartment 200 may include a freezer compartment door 210 and a shelf 220.

The freezing chamber door 210 is rotatably attached to the front surface of the freezing chamber 200 to selectively open and close the freezing chamber 200. As shown in FIG. 1, the freezing chamber door 210 may be rotated by being rotated up and down, for example. However, the freezing chamber door 210 may be opened and closed by a right and left rotating mechanism.

A plurality of shelves 220 can be positioned as in the refrigerating compartment 100, and foods are stored on the shelves 220.

1, the partition wall 300 is located between the refrigerating chamber 100 and the freezing chamber 200 and serves to partition the freezing chamber 100 and the freezing chamber 200.

The partition wall 300 includes the first heat insulating portion 310 and serves to insulate the freezing compartment 100 and the freezing compartment 200. Quot; first "substrate in the first adiabatic portion 310 is used only to distinguish it from the second adiabatic portion to be used subsequently. The second heat insulating portion is a term for collectively referring to the vacuum heat insulating material 500 and the heater 600, and is called by the heat insulating performance which is a common feature of both.

In general, the freezing chamber 100 is maintained at a temperature of the image, and the freezing chamber 200 is generally kept at a freezing temperature. Therefore, the freezing chamber 200 is generally maintained at a lower temperature than the freezing chamber 100.

The first heat insulating portion 310 of the partition wall 300 prevents the cold air of the freezing chamber 200 having a relatively low temperature from flowing into the refrigerating chamber 100 having a relatively high temperature.

Therefore, the first heat insulating portion 310 is required to have a thickness of a predetermined size or more. If the first adiabatic part 310 is too thin, the adiabatic effect can not be provided properly, and the cold air in the freezer compartment 200 flows into the refrigerating compartment 100.

The storage part 400 is located inside the partition wall 300 and is a space for storing food.

The storage portion 400 is recessed into the partition wall 300 as shown in Fig. 3 as an example.

4, when the upper part of the refrigerator is the refrigerating compartment 100 and the lower part is the freezing compartment 200, the upper part of the compartment wall 300 forming the bottom of the refrigerating compartment 100 320 in the direction of the freezing chamber 200, i.e., downward.

In this case, a storage unit door 410 for opening and closing the storage unit 400 is formed on the upper surface 320 of the partition wall 300 forming the bottom of the refrigerating chamber 100 as shown in FIG.

The storage unit door 410 can be opened and closed by sliding doors that are moved forward and backward by way of example. However, the storage unit door 410 is not limited to the opening and closing of the storage unit 400, Any structure that can be done is possible.

The receiving portion door 410 may include a receiving portion door receiving portion 412 in which the receiving portion door 410 can be selectively received when the receiving portion door 410 opens and closes the receiving portion 400 in a sliding manner.

In addition, the storage portion door 410 may include a handle portion 411.

The handle portion 411 is held by the user so that the door portion 410 is opened and closed.

Preferably, the receiving portion 400 is located below the door basket 111 extending rearward from the refrigerating chamber door 110 of the refrigerating chamber 100 located at the upper portion of the refrigerator.

In this case, the space below the door basket 111, which can not be used by the door basket 111, is used.

The length, length, and height of the storage portion 400 are not limited. However, it is preferable that the receiving part 400 is formed in a size that does not reach the lower part of the vegetable box 121 located at the rear in terms of easiness of storage with respect to the receiving part 400.

The use of the storage part 400 may be, for example, an egg storage part, but is not limited thereto. Since the egg storage portion is used for storing the eggs, it is necessary to maintain the temperature of the image. According to the present invention, since the second heat insulating part (500) prevents the cool air from the freezing chamber (200) from flowing into the storage part (400), the egg of the egg storage part can be maintained at the image temperature.

The vacuum insulator 500 is positioned between the storage part 400 and the refrigerating compartment 100 for heat insulation between the storage part 400 and the refrigerating compartment 100. Alternatively, the vacuum insulator 500 is positioned between the storage part 400 and the freezer compartment 200 for heat insulation between the storage part 400 and the freezer compartment 200. The vacuum insulator 500 insulates the space between the storage part 400 and the refrigerating compartment 100 when the temperature of the storage part 400 is below zero and when the temperature of the storage part 400 is an image, And the freezing chamber 200 is insulated.

The vacuum insulator 500 may be located, for example, in the lower portion of the storage portion 400 as shown in FIG. In other words, the vacuum insulator 500 may be positioned between the housing part 400 and the lower surface 330 of the partition wall 300. In this case, the vacuum insulator 500 insulates the space between the storage unit 400 and the freezer compartment 200 when the refrigerator compartment 100 is located at the upper part and the freezer compartment 200 is at the lower part. The vacuum insulator 500 serves to insulate the storage compartment 400 from the refrigerating compartment 100 if the refrigerating compartment 100 is located at the bottom and the freezing compartment 200 is located at the top.

The vacuum insulator 500 may be positioned at a lower portion of the storage portion 400 as described above but may be formed of a material having a high thermal conductivity such as a silicon carbide, In the present invention.

The vacuum insulating material 500 is superior in heat insulating performance to the insulating material constituting the first heat insulating portion 310. Therefore, it is possible to exhibit the heat insulating performance corresponding to the first heat insulating portion 310 even if the thickness is relatively reduced compared to the first heat insulating portion 310.

As an example, the first heat insulating portion 310 may be a heat insulating material including a plurality of bubbles therein.

In this case, the vacuum insulator 500 is manufactured by blowing a large number of bubbles to communicate with the outside, and then sucking air from the inside of the aluminum pack to make a plurality of bubbles into a vacuum state. As a result, a large number of bubbles in a vacuum state prevent heat conduction as well as heat convection. Accordingly, the vacuum heat insulating material 500 exhibits improved heat insulating performance than the first heat insulating part 310.

The heater 600 may be positioned on the heater seating portion 610 as shown in FIG. 5, for example, at a lower portion of the storage portion 400. In other words, the heater 600 may be positioned between the housing part 400 and the lower surface 330 of the partition wall 300. In this case, the heater 600 serves to insulate the space between the storage unit 400 and the freezer compartment 200 when the refrigerating compartment 100 is located at the upper part and the freezer compartment 200 is at the lower part. The heater 600 serves to insulate the storage compartment 400 from the refrigerating compartment 100 if the refrigerating compartment 100 is located below and the freezing compartment 200 is located above the refrigerator compartment 100.

The heater 600 may be disposed at a lower portion of the storage unit 400 as described above, but the heater 600 is not limited to the storage unit 400 and the freezing chamber 100, or the storage unit 400 and the freezing chamber 200, Any location that can insulate between the two ends can be located.

The heater 600 is superior in heat insulating performance to the heat insulating material constituting the first heat insulating portion 310. Therefore, it is possible to exhibit the heat insulating performance corresponding to the first heat insulating portion 310 even if the thickness is relatively reduced compared to the first heat insulating portion 310.

The heater 600 may include a separate power source for generating heat, but may generate heat using a power source supplied to the refrigerator.

According to an example of the present invention, the refrigerator according to the second embodiment may further include a control unit 620, a refrigerating room temperature sensor 630, and a freezing room temperature sensor 640 as shown in FIG.

 In this case, the control unit 620 maintains the temperature of the heater 600 at an appropriate temperature by using the difference between the refrigerating compartment temperature measured by the refrigerating compartment temperature sensor 630 and the freezing compartment temperature measured by the freezing compartment temperature sensor 640 do.

In addition, the refrigerator according to the second embodiment may have a separate receiving temperature sensor 650. In this case, the controller 620 can maintain the temperature of the heater 600 at an appropriate temperature by using the difference between the refrigerating compartment temperature and the compartment temperature, or the difference between the freezer compartment temperature and the compartment temperature.

Hereinafter, a method of using the storage compartment 400 of a refrigerator according to an example of the present invention will be described.
