Japanese Patent Application Publication No. 2008-106977

In a refrigerator where the refrigerant piping is led out of the refrigerator through the rear wall of the refrigerator, if the refrigerant piping protrudes from the rear of the refrigerator body to a large extent, the distance between the refrigerator and the wall when installing the refrigerator is Since a large gap is formed between the two, it is preferable that the protrusion dimension is as small as possible. However, in the refrigerator of Patent Document 1, after the cooling unit is fixed in a predetermined position, the refrigerant pipe on the refrigeration system side is connected to the end of the refrigerant pipe on the evaporator side that extends downward by welding, so welding work etc. In order to secure a working area, it was necessary to make the refrigerant piping on the evaporator side protrude significantly rearward from the rear wall of the main body, and there was a limit to reducing the rearward protrusion of the refrigerant piping. .

The present invention aims to facilitate the welding of the refrigerant piping during assembly in a refrigerator in which the refrigerant piping (inlet pipe and outlet pipe) of the evaporator is led out of the refrigerator through the rear wall of the refrigerator main body. It is an object of the present invention to provide a refrigerator that can simultaneously solve the contradictory problems of reducing the rearward protrusion of refrigerant pipes after assembly.

The refrigerator of the present invention includes a refrigerator main body 1 including a storage 4 having a front opening 3, an evaporator 12 inserted rearward from the front opening 3 and installed inside the storage 4, and an evaporator. An inlet pipe 24 that extends rearward from the evaporator 12 and supplies refrigerant to the evaporator 12, an outlet pipe 25 that collects refrigerant from the evaporator 12, and a , and a guide structure 32 for slidingly guiding the evaporator 12. The guide structure 32 allows the evaporator 12 to be slid within the storage compartment 4 between a fixed position where it is normally fixed and an assembly position installed on the rear side of the fixed position. The rear wall 26 of the storage 4 is provided with both pipes 24 corresponding to the transition locus of the inlet pipe 24 and the outlet pipe 25 when the evaporator 12 is slid from the fixed position to the assembled position by the guide structure 32. - It is characterized by being provided with a lead-out hole 27 that allows the lead-out of the container 25 to the outside of the refrigerator.

The inlet pipe 24 and the outlet pipe 25 are formed into straight tube shapes extending rearward from the evaporator 12.

The outlet hole 27 includes a first outlet hole 27A through which the inlet pipe 24 is inserted, and a second outlet hole 27B through which the outlet tube 25 is inserted.

The guide structure 32 includes a slide stopper 54 that prevents the evaporator 12 from sliding rearward beyond the assembled position.

The guide structure 32 includes a holding stop 53 that holds the evaporator 12 in a fixed position.

Like the refrigerator of the present invention, the evaporator 12 is normally fixed in the storage 4 between the fixed position where the evaporator 12 is fixed by the guide structure 32 and the assembly position installed on the rear side of the fixed position. The rear wall 26 of the storage 4 is configured to be slidable, and is provided with a guide structure 32 that corresponds to the transition locus of the inlet pipe 24 and the outlet pipe 25 when the evaporator 12 is slid from the fixed position to the assembled position. If the outlet hole 27 that allows both the pipes 24 and 25 to be led out of the refrigerator is provided, the tips of the inlet pipe 24 and the outlet pipe 25 can be led out when the evaporator 12 is placed in the assembled position. The tips of the inlet pipe 24 and the outlet pipe 25 can be made to protrude rearward from the rear wall 26 to a large extent through the hole 27, and when the evaporator 12 is placed in a fixed position, The protrusion dimension can be made relatively small compared to the above-mentioned assembly position. As described above, according to the present invention, when the evaporator 12 is disposed at the assembled position, the tips of the inlet pipe 24 and the outlet pipe 25 can be made to largely protrude rearward from the rear wall 26, so that the cooling mechanism side Assembling work such as welding work between the refrigerant pipe and the refrigerant pipe can be performed more easily. In addition, by displacing the evaporator 12 to the fixed position after welding, the tips of the inlet pipe 24 and the outlet pipe 25 are brought close to the refrigerator main body 1, and both pipes 24 and 25 are moved backward from the rear wall 26. Since the protruding dimension of the refrigerator can be reduced, the gap (dead space) formed between the refrigerator and the wall surface when installing the refrigerator can be reduced. As described above, according to the present invention, the welding work of the refrigerant pipes during assembly (the welding work between the refrigerant pipes (inlet pipe 24 and outlet pipe 25) on the evaporator 12 side and the refrigerant pipes on the cooling mechanism side) It is possible to simultaneously solve the contradictory problems of facilitating the assembly and reducing the rearward protrusion dimension of the refrigerant piping (refrigerant piping on the evaporator 12 side (inlet pipe 24 and outlet pipe 25)) after assembly. .

When the inlet pipe 24 and the outlet pipe 25 are formed in a straight tube shape extending rearward from the evaporator 12, the inlet pipe 24 and the outlet pipe 25 are formed in an L-shape including a bent vertical portion. Compared to the case where the tubes 24 and 25 are formed in an L-shape, the transition locus of the tubes 24 and 25 can be made smaller when the evaporator 12 is slid. The opening area of the lead-out hole 27 formed in this structure can be reduced. As described above, it is possible to suppress a decrease in the heat insulation performance of the refrigerator main body 1 due to the removal of the heat insulating material due to the formation of the through hole in the rear wall 26. Furthermore, the welding work can be performed more easily by eliminating the fact that the tube circumferential surfaces at the tips of both tubes 24 and 25 are opposed to the rear wall 26 of the refrigerator main body 1 when the evaporator 12 is in the assembled position. Can be done.

When the outlet hole 27 is composed of a first outlet hole 27A through which the inlet pipe 24 is inserted and a second outlet hole 27B through which the outlet tube 25 is inserted, both the tubes 24 and 25 are inserted through the outlet hole 27. The opening area of the outlet hole 27 (the total opening area of the first outlet hole 27A and the second outlet hole 27B) can be further reduced compared to the case where the outlet hole 27 is configured with one through hole. The deterioration of insulation performance can be further suppressed.

If the guide structure 32 includes a slide stopper 54 that prevents the evaporator 12 from sliding backward from the assembly position, the evaporator 12 collides with the inner surface of the rear wall 26 when sliding to the assembly position. Since this can be prevented, damage to the refrigerator main body 1 and the evaporator 12 can be avoided.

If the guide structure 32 is provided with the holding stopper 53 that holds the evaporator 12 at a fixed position, the evaporator 12 can be easily held at the fixed position using the holding stopper 53, so that the evaporator 12 can be easily held at the fixed position. The evaporator 12 can be easily assembled to the main body 1.

Further, the length of the fixed rail 46 in the front-rear direction is about half that of the movable rail 47, and is arranged in front of the front-rear center of the storage 4.

The cooling unit 6 is slidably guided by the guide structure 32 to the fixed position (FIG. 1(b)), and is also guided by the guide structure 32 to the rear (inner side) of the storage 4 from the fixed position. It is configured so that it can be slid to the assembled position (FIG. 1(a)). In the fixed position, the tips of the inlet pipe 24 and the outlet pipe 25 of this embodiment are in the thickness range of the rear wall 26 in front of the outside openings of the first and second outlet holes 27A and 27B (the outlet holes 27). In the assembled position, the openings protrude rearward from the outside openings of the first and second outlet holes 27A and 27B, and are spaced apart from the rear wall 26.

As shown in FIG. 5, the guide structure 32 includes a holding stopper 53 that holds the cooling unit 6 at a fixed position, and a slide stopper 54 that prevents the cooling unit 6 from sliding backward from the assembly position. Equipped with. A holding stopper 53 and a slide stopper 54 are provided on the right guide rail 34. Both stoppers 53 and 54 are provided downward in an engagement hole 55 formed in the receiving frame 49 of the fixed rail 46 and at the right end of the locking piece 50 of the movable rail 47, and are inserted into the engagement hole 55 and engaged. and an engaging claw 56.

More specifically, the engagement hole 55 is composed of a front engagement hole 55A, a middle engagement hole 55B, and a rear engagement hole 55C, and the three engagement holes 55A, 55B, and 55C are arranged equally in the front-rear direction. They are formed at intervals. The engagement claw 56 is composed of a front engagement claw 56A and a rear engagement claw 56B, and the two engagement claws 56A and 56B are formed at equal intervals in the front-rear direction. The longitudinal dimension of the engagement hole 55 is set to be slightly larger than the longitudinal dimension of the engagement claw 56, and the adjacent pitch of each engagement hole 55A, 55B, 55C and each engagement claw 56A. The adjacent pitch of 56B matches.

As shown in FIG. 1(b), the holding stopper 53 is composed of a front engagement hole 55A, a middle engagement hole 55B, a front engagement claw 56A, and a rear engagement claw 56B. is engaged with the front engagement hole 55A, and the rear engagement claw 56B is engaged with the middle engagement hole 55B, whereby the cooling unit 6 can be held at a fixed position. Further, as shown in FIG. 1(a), the slide stopper 54 is composed of a middle engagement hole 55B, a rear engagement hole 55C, a front engagement claw 56A, and a rear engagement claw 56B. The claw 56A engages with the middle engagement hole 55B, and the rear engagement claw 56B engages with the rear engagement hole 55C, thereby preventing the cooling unit 6 from sliding rearward from the assembly position. Can be done.

The evaporator 12 is assembled to the refrigerator main body 1 in a state where the evaporator 12 and the cooling fan 13 are fixed inside the unit case 10 to form a unit as the cooling unit 6. First, insert the cooling unit 6 in the depth direction of the storage 4 from the front of the front opening 3, hook the locking piece 43 on the upper surface of the receiving frame 41 of the left guide rail 33, and then attach the unit case 10 to the upper surface of the support plate 35. put it on. In this state, while sliding the cooling unit 6 in the depth direction, the locking piece 50 is hooked onto the upper surface of the receiving frame 49 on the right guide rail 34. When the cooling unit 6 is further slid in the depth direction from here, the rear end of the rear engaging claw 56B comes into contact with the front edge of the receiving frame 49, and the sliding at one end is blocked.

Next, when the lower part of the left side of the cooling unit 6 is pushed toward the right, the entire cooling unit 6 is rotated using the locking piece 43 received by the receiving frame 41 as a fulcrum, as shown in FIG. tilted counterclockwise. This rocking of the cooling unit 6 releases the rear engagement claw 56B from contact with the receiving frame 49, allowing the cooling unit 6 to slide in the depth direction again. When the cooling unit 6 is further slid in the depth direction from here, the front engagement claw 56A falls into the front engagement hole 55A, and the rear engagement claw 56B falls into the middle engagement hole 55B, thereby cooling the unit. The unit 6 is held at one end in a fixed position by a holding stopper 53. In addition, in the area where the engagement claw 56 vertically overlaps with the receiving frame 49 other than the area where the engagement hole 55 is formed, the cooling unit 6 is slid in a tilted state.

When the entire cooling unit 6 held at the fixed position is tilted counterclockwise again, the holding of the position by the holding stopper 53 is released, so that the cooling unit 6 can be slid in the depth direction. By sliding the cooling unit 6 further in the depth direction from here, the front engagement claw 56A falls into the middle engagement hole 55B, and the rear engagement claw 56B falls into the rear engagement hole 55C. The cooling unit 6 is prevented from sliding at the assembly position by a slide stopper 54. With the cooling unit 6 in the assembled position, the supply pipe 28 and the recovery pipe 29 are connected to the inlet pipe 24 and the outlet pipe 25 by welding.

The inlet pipe 24 and the supply pipe 28, and the outlet pipe 25 and the recovery pipe 29 are connected via an L-shaped connecting pipe 59 (see FIG. 8(a)). After sliding the cooling unit 6 to the assembly position, the connecting pipe 59 is connected to the inlet pipe 24 by welding (see FIG. 8(b)). Similarly, a connecting pipe 59 is connected to the outlet pipe 25 by welding. After connecting the connecting pipe 59 to both pipes 24 and 25, tilt the entire cooling unit 6 counterclockwise to release the slide stopper 54, slide the cooling unit 6 forward, and then close the holding stopper again. 53 to hold the position in a fixed position.

After moving the cooling unit 6 to the fixed position, the supply pipe 28 is connected to the connecting pipe 59 on the inlet pipe 24 side by welding, and the recovery pipe 29 is similarly connected to the connecting pipe 59 on the outlet pipe 25 by welding. (See Figure 8(c)). Finally, the fixing frame 40 and fixing piece 42 of the left guide rail 33 and the lower frame of the unit case 10 and the support plate 35 are each fastened together with the fastening screws 60 to complete the installation of the cooling unit 6. After the installation of the cooling unit 6 is completed, the gap between the supply pipe 28 and the first outlet hole 27A, and the gap between the recovery pipe 29 and the second outlet hole 27B is filled with caulking agent 61 to improve the insulation properties of the storage compartment 4. Ensure airtightness (see Figure 5). Note that when the cooling unit 6 is installed at a fixed position, the connecting pipe 59 is accommodated in a recess 62 provided in the rear wall 26 and communicating with the machine room 2, and is located inside the projected area of the refrigerator in a plan view. It is arranged. Therefore, the refrigerant piping does not protrude to the rear of the refrigerator.

As described above, in the refrigerator of this embodiment, the guide structure 32 allows the evaporator 12 to be moved between the fixed position where it is normally fixed and the assembly position installed on the rear side of the fixed position. , is configured to be slidable within the storage 4. According to this, when the evaporator 12 is disposed at the assembly position (see FIG. 1(a)), the tips of the inlet pipe 24 and the outlet pipe 25 are connected in the rearward direction from the rear wall 26 through the outlet hole 27. It can be made to protrude greatly. In addition, when the evaporator 12 is placed in a fixed position (see FIG. 1(b)), the protruding dimensions of the tips of the inlet pipe 24 and the outlet pipe 25 in the rear direction from the rear wall 26 are determined at the above-mentioned assembly position. It can be made relatively small compared to . As described above, when the evaporator 12 is placed in the assembled position, the tips of the inlet pipe 24 and the outlet pipe 25 can be made to protrude significantly rearward from the rear wall 26, so that there is a gap between the tips and the refrigerant pipes on the cooling mechanism side. Assembling work such as welding work can be carried out more easily. In addition, by displacing the evaporator 12 to the fixed position after welding, the tips of the inlet pipe 24 and the outlet pipe 25 are brought close to the refrigerator main body 1, and both pipes 24 and 25 are moved backward from the rear wall 26. Since the protruding dimension of the refrigerator can be reduced, the gap (dead space) formed between the refrigerator and the wall surface when installing the refrigerator can be reduced. As described above, according to the present embodiment, the welding work of the refrigerant piping during assembly (the refrigerant piping (inlet pipe 24 and outlet pipe 25) on the evaporator 12 side and the refrigerant piping (connecting pipe 59) on the refrigerant mechanism side) is performed. We have solved the conflicting issues of facilitating the welding work between the parts and reducing the rearward protrusion of the refrigerant pipes after assembly (the refrigerant pipes on the evaporator 12 side (inlet pipe 24 and outlet pipe 25)). can be solved at the same time.

Since the inlet pipe 24 and the outlet pipe 25 are formed into a straight tube shape extending toward the rear, the evaporator can be The transition locus of both the tubes 24 and 25 during the slide guidance of the tubes 12 can be made smaller. This makes the opening area of the outlet hole 27 formed in the rear wall 26 smaller than that in the case where the tubes 24 and 25 are formed in an L-shape, and the area of the outlet hole 27 formed in the rear wall 26 is made smaller. Since the size of the heat insulating material can be reduced, the deterioration of the heat insulating performance of the refrigerator main body 1 can be further suppressed. In addition, it is possible to eliminate the situation where the tube circumferential surfaces at the tips of both tubes 24 and 25 are opposed to the rear wall 26 of the refrigerator main body 1 when the evaporator 12 is in the assembled position, making welding work easier. can be done.

Since the outlet hole 27 is composed of a first outlet hole 27A through which the inlet pipe 24 is inserted and a second outlet hole 27B through which the outlet tube 25 is inserted, it is possible to use a single through hole through which both the tubes 24 and 25 can be inserted. Compared to the case where the outlet hole 27 is configured, the opening area of the outlet hole 27 (the total opening area of the first outlet hole 27A and the second outlet hole 27B) can be further reduced, and the heat insulation performance of the refrigerator main body 1 is improved. It is possible to further suppress the decrease in

Since the guide structure 32 is provided with a slide stopper 54 that prevents the evaporator 12 from sliding backward from the assembly position, the slide stopper 54 prevents the evaporator 12 from moving backward when sliding to the assembly position. Collision with the inner surface of the wall 26 can be prevented. Thereby, damage to the refrigerator main body 1 and the evaporator 12 can be reliably avoided.

Since the guide structure 32 is provided with the holding stopper 53 that holds the evaporator 12 at a fixed position, the evaporator 12 can be held at the fixed position more easily. Therefore, assembly of the evaporator 12 to the refrigerator main body 1 can be facilitated.

In addition to the above, the connecting pipe 59 can be omitted, and in this case, the inlet pipe 24 and the outlet pipe 25 are formed into an L-shape with a straight part and a vertical part, or the connecting pipe 28 and the collecting pipe 29 are formed in an L-shape. Bend the tip forward. Although the inlet pipe 24 is arranged on the left side and the outlet pipe 25 is arranged on the right side, the left and right arrangement may be reversed.
