Description

refrigerator

Embodiments of the present invention relate to a refrigerator.

In recent years, there has been a tendency to increase the internal volume of, for example, a household refrigerator, and the increase in the internal volume does not depend on the enlargement of the heat insulating box as the refrigerator body, but by making the thickness of the peripheral wall of the heat insulating box thin. And realized. In this case, even the thin peripheral wall must ensure sufficient thermal insulation properties. Therefore, the foaming heat insulating material is filled in the peripheral wall of the heat insulating box, and a vacuum heat insulating panel is used instead of the foaming heat insulating material.

The vacuum heat insulating panel is a panel in which, for example, a glass wool of a thin glass fiber, that is, glass wool, is formed into a mat shape and is set as a core material, and the core material is loaded into an aluminum foil. In the gas barrier container made of a laminated film of synthetic resin, the inside is evacuated and the opening is blocked, whereby the inside of the container is maintained in a vacuum decompressed state. Vacuum insulated panels, even if they are thin, have a low thermal conductivity, ie a high thermal insulation. Therefore, by using the vacuum heat insulating panel, the peripheral wall of the heat insulating box can maintain high heat insulation.

The condensing duct 16 suppresses the generation of dew by heating the peripheral edge of the front opening portion of the heat insulating casing 1 and the horizontal frames 12, 13, and 14 and the vertical frame 15.

As shown in Fig. 1, the refrigerant condensed by the condensing pipe 16 is supplied to each of the evaporators for refrigeration and freezing via the two capillary tubes 17 for refrigeration and freezing. The refrigerant evaporated by each evaporator is sucked to the compressor via the suction pipes 18, 19. The capillary tube 17 and the suction pipes 18 and 19 are provided outside the storage space 5 with respect to the heat insulating box 1 . In the present embodiment, the capillary tube 17 and the suction pipes 18 and 19 are provided inside the wall portions 1a to 1e of the heat insulating box 1, and are, for example, a heat insulating box that is a connecting portion between the right wall portion 1d and the inner wall portion 1e. The inside of the corner portion of the right lateral rear side of the body 1, that is, the inside of the angular portion of the heat insulating box 1 where the ends of the right side wall portion 1d and the inner wall portion 1e intersect each other.

The arrangement position of the capillary tube 17 and the suction pipes 18 and 19 will be described below in relation to the vacuum heat insulating panels 4d and 4e. In other words, the capillary tube 17 and the suction pipes 18 and 19 are disposed on the outer side of the rear end of the vacuum heat insulating panel 4d of the right side wall portion 1d, that is, the outer side, and the outer casing 2d, that is, the outer casing 9d of the right side wall portion 1d. On the inner side, the right end of the vacuum heat insulating panel 4e of the inner wall portion 1e is extended to the outer side, and is closer to the inner side than the end piece of the outer box 2, that is, the connecting piece 11 of the right side wall portion 1d. In this case, the rear end of the vacuum heat insulating panel 4d in which the capillary tube 17 and the suction pipes 18 and 19 are disposed is referred to as the end on the piping arrangement side with respect to the vacuum heat insulating panel 4d of the right side wall portion 1d. also, In the vacuum heat insulating panel 4e of the inner wall portion 1e, the right end of the vacuum heat insulating panel 4e in which the capillary tube 17 and the suction pipes 18 and 19 are disposed is referred to as an end on the piping arrangement side.

The rear end of the vacuum heat insulating panel 4d of the right side wall portion 1d is a connecting piece 11 that does not reach the end of the right side wall portion 1d, that is, the rear end of the outer casing 9d, but is located further inside than the connecting piece 11. Further, the right end of the vacuum heat insulating panel 4e of the inner wall portion 1e is not located at the end of the inner wall portion 1e, that is, the right end of the outer casing 9e, but is located further inside than the right end of the outer casing 9e. Thereby, a space is formed between the two vacuum heat insulating panels 4d and 4e, and the capillary tube 17 and the suction pipes 18 and 19 are disposed in the space.

In this case, a square shape rod-shaped heat insulating member 20 made of, for example, a foamable plastic having rigidity is housed inside the corner portion on the right lateral rear side of the heat insulating box 1. Two suction pipes are provided. 18 and 19 are inserted together with the capillary tube 17 into the groove 20a formed in the rod-shaped heat insulating member 20. A sponge-like heat insulating material 21 is provided between the rod-shaped heat insulating member 20 and the right end of the vacuum heat insulating panel 4e of the inner wall portion 1e. Therefore, the two suction pipes 18 and 19 and the capillary tube 17 are insulated by the rod-shaped heat insulating member 20 and the sponge-shaped heat insulating material 21.

The inner casing 10d of the right side wall portion 1d extends rearward from the inner casing 10e of the inner wall portion 1e. Therefore, the space generated on the rear side of the vacuum heat insulating panel 4d in the right side wall portion 1d and the space generated on the right side of the vacuum heat insulating panel 4e in the inner wall portion 1e are by the inner casing 10d of the right side wall portion 1d. Divide a part of it. The capillary tube 17 and the suction pipes 18 and 19 housed in the rod-shaped heat insulating member 20 are disposed on the rear side of the vacuum heat insulating panel 4d in the right side wall portion 1d. Within the space produced.

The rod-shaped heat insulating member 20 is formed in a cross-sectional square shape such as the size of the space between the rear end of the vacuum heat insulating panel 4d that occupies the right side wall portion 1d and the connecting piece 11 of the outer casing 9d. Moreover, the length of the rod-shaped heat insulating member 20 in the vertical direction is set to a length dimension from the lower end of the right side wall portion 1d to the lower portion of the rear portion of the top wall portion 1a.

The suction pipes 18, 19 and the capillary tube 17 are assembled as follows, and are disposed inside the corner portion of the right lateral rear side of the heat insulating box 1. Furthermore, the assembly method is an example and is not limited thereto. First, the capillary tube 17 and the suction pipes 18 and 19 are inserted into the groove 20a of the rod-shaped heat insulating member 20, and are unitized, that is, integrated with the rod-shaped heat insulating member 20. In this case, in order to integrate the capillary tube 17 and the suction pipes 18 and 19 and the rod-shaped heat insulating member 20 more firmly, it may be fixed by an adhesive. Further, as shown in FIG. 2, the upper end portions of the capillary tubes 17 and the suction pipes 18, 19 are protruded upward from the upper end of the rod-shaped heat insulating member 20 by a desired length. Thereafter, the lower end portions of the suction pipes 18 and 19 and the capillary 17 are protruded from the intermediate portion of the rod-shaped heat insulating member 20 by the required length in the lateral direction in accordance with the arrangement position of the evaporator in the heat insulating box 1.

Next, the unitized rod-shaped heat insulating member 20 is attached to the inner surface of the outer casing 9d of the right side wall portion 1d so as to be in contact with the connecting piece 11 at the rear end portion. Thereafter, the vacuum heat insulating panel 4d is attached to the inner surface of the outer casing 9d in a state where the rear end of the vacuum heat insulating panel 4d is in contact with the rod-shaped heat insulating member 20. Moreover, the inner casing 10d is followed by the vacuum insulation panel 4. At this time, the details are not shown, but are made from the lower end of the rod-shaped heat insulating member 20. The suction pipes 18 and 19 protruding from the portion and the capillary tube 17 protrude from the slit formed in the inner casing 10d toward the accommodating space side.

In addition, the capillary 17 and the suction pipes 18 and 19 integrated with the rod-shaped heat insulating member 20 are housed in the inner right rear corner portion of the heat insulating box 1 by joining the right wall portion 1d and the inner wall portion 1e. . Thereafter, when the top wall portion 1a, the right side wall portion 1d, and the inner wall portion 1e are combined, the capillary 17 and the suction pipe 18 projecting upward from the upper end of the rod-shaped heat insulating member 20, that is, from the upper end of the right wall portion 1d. 19 is introduced into the machine room 6 through a through hole (not shown) formed in the top wall portion 1a.

The capillary 17 introduced into the machine chamber 6 is connected to the end portion of the condenser 16 via a three-way valve disposed in the machine chamber 6. The two suction pipes 18, 19 are connected to the suction port of the compressor via a joint. The refrigerant discharged from the compressor is supplied to the refrigerating evaporator or the freezing evaporator via the condenser 16 and by the action of the three-way valve. Further, the refrigerant evaporated by any evaporator is sucked into the compressor via the suction pipe 18 or the suction pipe 19.

In this way, the capillary 17 and the suction pipes 18 and 19 which are pipes are disposed outside the storage space 5. Therefore, unlike the case where the plurality of pipes are disposed inside the storage space 5, it is possible to suppress the storage space 5 from being narrowed by the piping. Therefore, the storage space 5 can be widely used for food storage.

Further, although the low-temperature refrigerant flows through the suction pipes 18 and 19, the capillary 17 and the suction pipes 18 and 19 are covered with the heat insulating materials 20 and 21, so that dew condensation can be suppressed.

Moreover, since the capillary tube 17 and the suction pipes 18 and 19 and the foaming heat insulating material 20 are unitized, it becomes easy to handle at the time of assembly. Moreover, due to foaming Since the heat insulating material 20 has rigidity, it can be operated as compared with the case of softness, and the work of accommodating the capillary tube 17 and the suction pipes 18 and 19 in the groove 20a can be easily performed.

Further, the heat insulating box 1 is configured by combining a plurality of wall portions 1a to 1e. Therefore, the operation of accommodating the capillary tube 17 and the suction pipes 18 and 19 in the corner portion which is a joint portion between the right wall portion 1d and the inner wall portion 1e can be relatively easily performed. Here, it is particularly effective when the thickness of the left and right wall portions 1c and 1d is 35 mm or less. In the case of this embodiment, the thickness of the vacuum heat insulating panel 4 is set to about 20 mm. Further, the total thickness of the outer casing 9 and the inner casing 10 is set to be about 1.5 mm. In this case, the total thickness of the vacuum heat insulating panel 4, the outer casing 9, and the inner casing 10 is 21.5 mm. That is, the thickness of the left and right wall portions 1c and 1d is configured to be more effective at a thickness of 25 mm or less.

Fig. 7 shows a second embodiment. The second embodiment differs from the first embodiment in the method of arranging the capillary tube 17 and the suction pipes 18 and 19. That is, in the second embodiment, the groove 20a of the rod-shaped heat insulating member 20 having a square cross section is formed on the diagonal line from the corner portion of the inner box 3 toward the corner portion of the outer box 2. In the tank 20a, a plurality of pipes are arranged in parallel, and in this case, a total of four pipes of the two capillary tubes 17 and the suction pipes 18 and 19 are provided.

Thus, the suction pipes 18 and 19 thicker than the capillary 17 are arranged on the diagonal line at the angular portion of the heat insulating box 1, even if the suction pipes 18 and 19 are thicker than the vacuum heat insulating panel 4. At the same time, it can also be accommodated in the angular portion of the heat insulating box 1.

As shown in Fig. 10, the two face portions 23a and 23b of the covering member 23 intersect at right angles and have a L-shaped cross section. The front end portions of the two face portions 23a and 23b are curved inward. Thereby, the cross section of each of the face parts 23a and 23b is a container shape.

The foamable heat insulating material 24 is filled inside the respective face portions 23a and 23b. A groove 24a is formed in the foamable heat insulating material 24 on the side of the face portion 23b. In the groove 24a, two suction pipes 18 and 19 are housed together with the capillary tube 17.

In the face portion 23a of the covering member 23, a concave portion 25a is intermittently formed in the vertical direction. Similarly, in the face portion 23b of the covering member 23, a concave portion 25b is intermittently formed in the vertical direction. The self-tapping screw 26a is passed through the recess 25a of one of the face portions 23a. This tapping screw 26a is screwed into the outer casing 9d of the right side wall portion 1d. Further, the self-tapping screw 26b passes through the concave portion 25b of the other face portion 23b. The tapping screw 26b passes through a through hole (not shown) formed in the outer casing 9 of the inner wall portion 1e, and is screwed into the connecting piece 11 of the outer casing 9 of the right side wall portion 1d. In this manner, the covering member 23 is fixed to the outside of the corner portion of the right rear portion of the heat insulating box 1.
