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 the partition wall including the heat insulating part for heat insulation is positioned between the freezing compartment and the freezing compartment.

In recent years, there has been an attempt to form 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 An object of the present invention is to provide a refrigerator in which heat insulating efficiency of a portion of a heat insulating portion that is relatively thinned by a receiving portion formed by being recessed in a partition wall is improved.

And FIG. 4 is a cross-sectional view taken along line AA of FIG.

1 to 4, a refrigerator according to a 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 .

For 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 above the freezing chamber 200, 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 chamber 100 can maintain the temperature of the image, though it is not limited thereto, and the food to be stored at the image temperature can be stored and stored.

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

The refrigerating chamber 100 may include a refrigerating chamber door 110 and a plurality of shelves 120.

The refrigerator compartment door 110 is rotatably connected to a main body of the refrigerator compartment 100 to selectively open and close the refrigerating compartment 100.

The refrigerator compartment door 110 may include a door basket 111, for example. The door basket 111 protrudes from the refrigerator compartment door 110 toward the refrigerating compartment, i.e., rearward. Alternatively, the door biscuit 111 may be detachably connected to the rear side of the refrigerator compartment door 110. The door basket 111 may extend to the front of the vegetable box 121, which will be described later, as shown in FIG. The door basket 111 may have a width and a width to accommodate a water bottle, a beverage bottle containing a capacity of 1.5 L or more, but is not limited thereto.

The receiving portion 400 may be located below the door basket 111, as will be described later.

One or more shelves 120 may be provided in the refrigerating chamber 100. For example, but not limited to, four shelves in FIG. 2, the shelves 120 may be selectively removable from the refrigerating compartment 100 by a user. The shelf 120 functions to divide the entire space of the refrigerating chamber 100 up and down. Food and the like can be stored on the shelf 120.

The lower portion of the shelf 120 located at the bottom of the refrigerating chamber 100 may be provided with a vegetable box 121, although not limited thereto.

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 sidewalls extending upward to prevent vegetables from being poured therein.

The vegetable box 121 is slid forward so that the vegetable box 121 is ready for storing vegetable products such as vegetables and the like when the user grips the handle portion of the vegetable box 121 and pulls it forward. In addition, when the vegetable box or the like is housed and then pushed rearward, the open upper portion of the vegetable box 121 is completely closed by the shelf 120 located at the lowest position in the refrigerating compartment 100, .

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

The temperature of the freezing chamber 200 may be changed as the user operates the freezing chamber temperature control button (not shown) and may be set to the temperature of the image according to the user's operation.

The freezing chamber 200 may include a freezing chamber door 210 and a shelf 220. Of course, depending on the type of refrigerator, the shelf 220 may be omitted.

The freezing chamber door 210 may be rotatably or slidably connected to the main body.

1, the freezer compartment door 210 may be opened and closed by rotating it in a horizontal direction, for example, although it may be opened and closed by being rotated up and down as shown in FIG. Alternatively, the freezing chamber door 210 may slide in the front-rear direction to open and close the freezing chamber 200.

One or more shelves 220 can divide the freezer compartment 200 up and down, and food can be placed on the shelves 220.

The refrigerating chamber 100 and the freezing chamber 200 may be partitioned by a partition wall 300.

The partition wall 300 includes the first heat insulating portion 310 and serves to insulate the freezing chamber 100 and the freezing chamber 200. The "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.

A known heat insulating material such as polyurethane or polystyrene can be used for the first heat insulating part 310, and a detailed description thereof will be omitted.

The freezing chamber 200 is maintained at a temperature lower than that of the refrigerating chamber 100 because the freezing chamber 200 is generally kept at a freezing temperature .

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

Therefore, it is required that the first heat insulating part 310 has a thickness of a predetermined size or more. When the first heat insulating portion 310 is too thin, the heat insulating effect is small and the temperature of the refrigerating chamber 100 becomes lower than the temperature required by the freezing of the freezing chamber 200.

The compartment wall 300 may be provided with a storage unit 400, which is a space for storing food. As shown in FIG. 3, the upper surface of the partition wall 300 is recessed downward.

4, when the refrigerating compartment 100 is located on the upper portion of the refrigerator and the freezing compartment 200 is located on the lower portion of the refrigerator 100, And is recessed from the upper surface 320 of the partition wall 300 toward the freezing chamber 200, that is, downward.

3, the compartment door 410 for opening and closing the compartment 400 is disposed on the upper surface 320 of the compartment wall 300 forming the bottom of the refrigerating compartment 100 .

The storage unit door 410 may be opened and closed in a sliding manner forward and backward by way of example, but the present invention is not limited thereto. The storage unit 400 may be selectively opened Any structure that can be opened and closed is possible.

The partition wall 300 may include a door portion receiving portion 412 that can selectively receive the door portion 410 of the compartment 300 when the compartment door 410 opens and closes the compartment 400 in a sliding manner ).

In addition, the storage unit door 410 may include a handle 411. The handle 411 is held by a user to open and close the door 410.

The storage compartment 400 may be located below the door basket 111 extending rearward from the refrigerator compartment door 110 of the refrigerating compartment 100.

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

The width, length, and height of the storage part 400 are not limited. However, from the viewpoint of ease of storage with respect to the storage part 400, the storage part 400 is formed such that the vegetable box 121 located at the rear side does not cover more than 1/2 of the storage part 400 .

The storage unit 400 may contain an egg, but is not limited thereto. When eggs are stored in the storage unit 400, the temperature of the storage unit 400 needs to be maintained as an image.

In this embodiment, the second insulation unit is provided in the storage unit 200 to maintain the temperature of the storage unit 400 as an image. As described above, the second adiabatic portion may include a vacuum insulator 500.

The vacuum insulator 500 may be disposed on the storage compartment door 410 for heat insulation between the storage compartment 400 and the refrigerating compartment 100. The vacuum insulator 500 is positioned between the accommodating part 400 and the freezing compartment 200 for heat insulation between the accommodating part 400 and the freezing 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, The space between the storage part 400 and the freezing chamber 200 can be insulated.

The vacuum insulator 500 may be positioned below the storage unit 400 as shown in FIG. In other words, the vacuum insulator 500 may be positioned between the bottom of the compartment 400 and the lower surface 330 of the partition wall 300. When the refrigerating chamber 100 is located above the freezing chamber 200, the vacuum insulating material 500 insulates the receiving chamber 400 from the freezing chamber 200. The vacuum insulator 500 insulates the space between the storage unit 400 and the refrigerating compartment 100 when the refrigerating compartment 100 is located below the freezing compartment 200.

The vacuum insulator 500 may be located at a lower portion of the accommodating portion 400 as described above but is not limited thereto and may include the accommodating portion 400 and the freezing compartment 100 or the compartment 400, It is possible to arrange any position capable of performing the heat insulation between the first and second heaters 200.

The vacuum insulation material 500 is superior in heat insulation performance to the insulation material constituting the first heat insulation part 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.

For example, the first heat insulating part 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. Therefore, the vacuum heat insulating material 500 exhibits improved heat insulating performance than the first heat insulating part 310.

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

More specifically, a heat insulating function is performed between the storage part 400 and the refrigerating compartment 100, or between the compartment 400 and the freezing compartment 200. In addition, the heater 600 may be used to prevent dew formation on the inner wall of the heater seat 610.

5, the heater 600 may be mounted on the heater seating portion 610 and may be located below the receiving 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. When the refrigerating chamber 100 is located above the freezing chamber 200, the heater 600 insulates the receiving chamber 400 from the freezing chamber 200. When the refrigerating chamber 100 is located above the freezing chamber 200, the heater 600 insulates the receiving chamber 400 from the refrigerating chamber 100.
