Description

[Detailed Description of the Invention] The present invention relates to a refrigerator having an inner box in which a recess for a freezer compartment and a recess for a refrigerator compartment are integrally formed.

Conventionally, in this type of refrigerator, it has been known to provide a condensing refrigerant pipe in the refrigerant circuit as a measure to prevent sweating on the front side of the connecting wall, that is, the partition wall that connects the recesses. The arrangement structure for this refrigerant pipe inside the partition wall was generally to arrange it on the back side of the thermally conductive front plate constituting the partition wall, but in the case of a refrigerator having the above-mentioned inner box, If the refrigerant pipe is placed in front of the connecting wall that connects the two recesses in a case that has an inner box in which the room recess and the refrigerator recess are integrally molded, the front plate may become larger than necessary due to the diameter of the pipe. The protrusion caused an inconvenience, and in the end, it was necessary to rely on the conventional electric heater. The first object of the present invention is to eliminate such drawbacks and to provide a structure in which a refrigerant pipe can be used to prevent perspiration even in a refrigerator that uses an inner box in which each recess is integrally molded.

Furthermore, in refrigerators that have a freezer compartment and a cold storage compartment, there is a difference in the degree of sweating at the front of the compartment wall due to the difference in internal temperature. There was a defect that could not be expected to prevent sweating and caused sweat to be concentrated in low temperature rooms such as freezers. A second purpose of the present invention is to structurally solve this drawback.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a refrigerator body, which is composed of an inner box 2, an outer box 3, and a heat insulating material 4 filled between both boxes 2 and 3. This main body 1 has a refrigerator compartment 5 in the upper part, a freezer compartment 6 on the left and right sides of the lower part, and a vegetable compartment 7 respectively, and a well-known magnetic gasket (not shown) is installed on the front of each.
Doors 8, 9, and 10, which seal the interior of the room, are pivotally mounted to open and close at will. The inner box 2 is integrally molded from a synthetic resin sheet and has a recess 2a for the refrigerator compartment, a recess 2b for the freezer compartment, and a recess 2c for the vegetable compartment, respectively. is at the connecting wall 2d,
The recesses 2b and 2c are divided and connected by a connecting wall 2e. 2f and 2g are connection walls 2d and 2g, respectively.
This is a band-shaped groove that is integrally formed with the groove 2e so as to be recessed inwardly, and as is clear from FIG. Reference numeral 2h denotes a flange extending horizontally to the outside of each recess 2a, 2b, 2c, and is inserted into a double flange 3' formed at the front edge of the opening of the outer box 3. Reference numeral 2i denotes a groove formed in the flange 2h that is continuous with the band-shaped grooves 2f and 2g formed in the connection walls 2d and 2e. The band-shaped grooves 2f and 2g are the kerf grooves 2.
It does not extend to other flange parts other than i. Further, the cut groove 2i is arranged toward the freezer compartment recess 2b side. Reference numeral 11 denotes a refrigerant pipe forming a part of a condensing refrigerant circuit of a well-known refrigeration cycle (not shown) provided in the main body 1, and is disposed within the double flange 3' of the outer box 3, that is, around the front opening of the main body 1. It has a portion 11a and a portion 11b bent into a T-shape to be disposed within the band-shaped grooves 2f and 2g.

Next, to explain the assembly order of the outer box 3, inner box 2, and refrigerant pipe 11, first, the part 11 of the refrigerant pipe 11
a is disposed within the double flange 3' of the outer box 3.

Then, the portion 1 disposed in the belt-shaped grooves 2f and 2g
Although not shown, bend 1b outward and make it stand up.
Then, connect the flange 2h of the inner box 2 to the double flange 3'.
Insert inside. At this time, the flange 2h of the inner box 2
The cut groove 2i formed at the bottom end of the refrigerant pipe 11
This serves as a pull-out portion from the portion 11a to the portion 11b so as not to interfere with the insertion of the flange 2h. After that, the refrigerant pipe 1 that is erected
The portion 11b of 1 is arranged along the band-shaped grooves 2f and 2g.

Further, reference numeral 12 denotes a front plate having thermal conductivity and made of a magnetic material (for example, an iron plate) which covers the connecting walls 2d and 2e after being assembled in this way, and is a front plate that covers the connecting walls 2d and 2e.
It constitutes the adsorption surface of the magnetic gasket and the front surface of the partition wall.

Therefore, the portion 1 of the refrigerant pipe 11 is placed outside the connecting wall 2d of the inner box 2 formed of a synthetic resin sheet.
1b is located, and this portion 11b is covered by the front plate 12, so that the heat of the refrigerant pipe 11 acts more effectively on the front plate 12 and prevents condensation compared to when the refrigerant pipe is disposed on the back side of the connecting wall 2d. Ru. Also, front plate 1
2 can be used as an adsorption surface for the magnetic gaskets of the doors 8, 9, and 10, so that leakage of cold air can be prevented.

Also, a section 11b of the refrigerant pipe 11 is formed by a cut groove 2i formed at one location of the flange 2h of the inner box 2.
Since the inner box 2 can be led out to the front of the connecting wall 2d, it is easy to assemble the inner box 2 to the outer box 3. Furthermore, since the inner box 2 is located in the band-shaped grooves 2f and 2g of the connecting wall 2d, the refrigerant pipe 11 part 11b can be easily positioned.

Furthermore, since the inner box is formed by integrally forming the recess for the freezer compartment and the recess for the refrigerator compartment with a synthetic resin sheet, there is no need to separately form a partition wall to separate the freezer compartment and the refrigerator compartment, as in the past. , the number of parts can be reduced.

As is clear from the description of the above embodiments, the refrigerator of the present invention has an inner box in which a recess for the freezer compartment and a recess for the refrigerator compartment are integrally molded. Since the refrigerant pipe can be disposed outwardly, the heat of the refrigerant pipe can be transferred to the front plate, and the amount of heat dissipated from the refrigerant pipe can at least prevent dew condensation.

Therefore, the amount of heat dissipated from the refrigerant pipes is smaller than that from the refrigerant pipes located on the back side of the connection wall, so there is less heat intrusion into the refrigerators, and the power consumption of the refrigerators can be reduced. Furthermore, since the front plate is made of a magnetic material that has thermal conductivity, it can be used as an attraction surface for the magnetic gasket of the door, thereby preventing cold air from leaking to the outside.

In addition, the kerf formed on the flange of the inner box and the band-shaped groove formed on the connecting wall are continuous, and the kerf is formed in one place on the flange, so the refrigerant pipe is connected from the part corresponding to this kerf. By leading out the part accommodated in the connecting wall of the refrigerant pipe, the refrigerant pipe does not get in the way when inserting the inner box into the outer box. Moreover, since the portion of the refrigerant pipe located on the connecting wall is accommodated in the band-shaped groove, positioning can be easily performed without a separate positioning means.
Furthermore, since the recess for the freezer compartment and the recess for the refrigerator compartment are integrally molded from synthetic resin, there is no need to separately prepare a partition wall that partitions the refrigerator compartment and the freezer compartment. Furthermore, since the portion of the refrigerant pipe inserted into the double flange and the portion disposed on the connection wall are bent and formed integrally, the pipes can be simplified without any work to connect them. In addition, since the refrigerant pipe is placed close to the low-temperature room side, it is possible to efficiently prevent sweating.
