Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooling storage, and more particularly to a type in which a cooling device can be pulled out.

[0002]

[Prior art]

 In order to facilitate the assembly and maintenance of the cooling unit, some proposals have been made so far that the entire unit can be pulled out from the housing side. Examples thereof include JP-A-4-151479 and Japanese Utility Model Laid-Open No. 63-43074. In the case where the cooling unit is detachably incorporated in this way, the following points must be noted. This will be described with reference to FIG. First, the structure will be briefly described. Reference numeral 50 is a storage chamber for storing stored items, and a cooling chamber 52 is provided on a side portion thereof. A circulation fan 53 and a cooler 51 are provided here. The circulation fan 53 is fixed to a corner on the storage chamber side on the upper surface of the cooling chamber 52, whereas the cooler 51 whose side surface is surrounded by the cover member 54 is pulled out to the outside by a supporting means (not shown) (front direction in the drawing). Withdrawal to) built in possible.

Further, the storage chamber 50 and the cooling chamber 52 are partitioned by a partition plate 55, in which an outlet 56 for letting out the air in the storage chamber 50 and an air cooled by the cooler 51 are provided. An inflow port 57 is opened to allow the circulation fan 53 to flow into the storage chamber 50. Here, it should be noted that it is necessary to avoid a situation where the air from the storage chamber 50 is immediately sucked by the circulation fan 53 without passing through the cooler 51. Conventionally, a shield plate 58 (which also serves as a guide for the inflow air to the cooler 51) is provided as a measure for eliminating this, and this partitions the inside of the cooling chamber 52 and allows the inflow air and the outflow to the cooler 51. I was trying not to mix with the air. In particular, since the cooling device can be pulled out, the shield plate 58 cannot fix both ends of the partition plate 55 side and the cooler 51 side. Therefore, although the edge on the side of the partition plate 55 is fixed, the edge on the side of the cooler 51 is a free end, and it is merely applied to the cover material 54 of the cooler 51 through the seal rubber 59 along the depth direction. It had a structure of.

[0004]

[Problems to be solved by the device]

 However, in such a simple application method, the sealing property between the shield plate 58 and the cooler 51 is impaired, and the air (inflow air) from the storage chamber 50 does not pass through the cooler 51 and is directly fed. There is a problem that the cooling fan 53 flows into the space where the circulation fan 53 is housed, and as a result, the cooling efficiency is lowered. The reasons for this are as follows. In the case of this, in order to ensure the proper sealing property, it is necessary that the edge of the shield plate 58 is in close contact with the cover member 54 of the cooler 51 along the pulling direction in its entire width. Become. For that purpose, the contact surface on the cover material 54 side must be parallel to the free end side edge of the shield plate 58 with the cooler 51 incorporated.

However, the cooler 51 is attached to the lid plate 60 that closes the opening surface of the cooling chamber 52, but at this time, the cooler 51 is not perpendicular to the mounting surface 60 a of the lid plate 60. It may not be obtained. In such a case, the edge of the shield plate 58 gradually separates from the cover material 54 as it goes deeper, resulting in a loss of the sealing performance in the inner part. As another cause, the cooler 51 is properly attached to the cover plate 60, but the surface around the opening of the cooling chamber 52 does not face the front exactly, and is assembled by twisting around the vertical axis. May be Since the cover plate of the cooler is fastened and fixed to this surface, the cooler 51 is stored obliquely with the original storage axis displaced. As a result, the edge of the shielding plate 58 and the cover member 54 are separated from each other, as described above. If it does not follow, the sealability will be impaired.

The present invention has been devised and devised in view of such circumstances, and its purpose is to ensure the sealing property of the inflow and outflow air to the cooling device to achieve the desired cooling. It is to provide a cooling storage that realizes efficiency.

[0007]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above-mentioned object is such that the inside of the housing is a storage chamber for storing a storage, and a cooling chamber which is arranged adjacent to the storage chamber and stores the cooling device so as to be drawn out. In addition, an opening for inflow and an opening for outflow for circulating cold air are opened at the boundary between the storage chamber and the cooling chamber so that the two chambers can communicate with each other, and A cooling storage cabinet in which a shielding plate for partitioning circulating air to the inflow opening and the outflow opening is formed so as to face the other side from either the chamber side or the cooling device side. A sealing edge is formed along the pulling direction of the cooling device on one of the edge of the shielding plate and the surface facing the shielding plate, and a guide groove for receiving this is formed on the other side. hand It is characterized by being present.

[0008]

[Action]

 When the cooling device is pulled out or installed, the cooling rim is engaged with the guide groove. At this time, even if the cooling device does not have a right angle, the sealing edge between the seal edge and the guide groove is forcibly secured by the engagement between the seal edge and the guide groove. Is led to the cooler.

[0009]

[Effect of device]

 The effects of the present invention are as follows. Since the shield plate is interposed between the storage chamber side and the cooling device side, and the free end of the shield plate can be reliably sealed by the engagement of the seal edge and the guide groove, the air flow during heat exchange is prevented. You can follow the regular route. Therefore, the efficiency of heat exchange can be improved.

 Embodiments embodying the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the refrigerator of this example is provided with a plurality of drawer-type storages a, and the cooling unit 9 is removably stored in the side portion thereof. The housing 2 of the refrigerator is formed in a box shape that opens to the front, and a storage chamber 3 is formed inside the housing 2 corresponding to each of the storages a described above. Although not shown in detail, the front surface is partitioned in a grid shape, and each storage a is supported so that it can be individually put in and taken out from the storage a. In addition, as shown in FIG. 3 and the like, a heat insulating material 21 is embedded inside each wall constituting the housing 2 so as to ensure the heat insulating properties of the storage chamber 3 and the cooling chamber 4 adjacent thereto. There is.

As shown in FIG. 2, the cooling chamber 4 is provided with a bulging portion 5 which is provided so as to project outward on a side portion of the housing 2 and to be slightly retracted from the front surface of the housing 2. It is formed inside. A storage space 8 for receiving the condenser 6, the compressor 7 and the like is provided below the bulging portion 5, and the storage space 8 and the cooling chamber 4 allow the condenser 6 and the compressor 7 to be described above. The cooling unit 9 configured by the cooler 1 and the like is retractably stored. In the storage space 8, one side edge 10a of a receiving plate 10 formed in a shallow dish is fixed to the lower edge of the side surface of the housing 2. A channel material 11 is fixed to the lower edge of the side surface of the bulging portion 5 along the same edge, and two connecting portions are provided between both end portions of the channel material 11 and the opposite side edges of the receiving plate 10. The bar 12 is interposed so that the entire receiving plate 10 is held. On the other hand, in the receiving plate 10, only the front edge is not formed along the entire side edge, but the base plate 13 of the cooling unit 9 (formed in a downward U shape in which both side edges are bent). Only the two screw receiving pieces 10b are formed upright in order to avoid interference with the like.

The cooling unit 9 is fixed on the above-mentioned base plate 13, and when the cooling unit 9 is stored, screws are inserted from both screw insertion holes 15 of the mounting member 14 attached to the front edge of the base plate 13, The entire cooling unit 9 is fixed by screwing the screw receiving piece 10b. Further, the mounting member 14 is formed of a channel material, and the lower edge of the front panel 17 is inserted into the groove portion 14b as shown in FIG. 1, and is fixed to the mounting member 14 by a screw (not shown). ing. As shown in FIG. 2, the cooling unit 9 is divided into a portion to be stored in the storage space 8 and a portion to be stored in the cooling chamber 4, and these are arranged vertically on the base plate 13 in a stacked manner. . A compressor 7 is arranged on the back side and a condenser 6 is arranged on the front side as parts to be stored in the storage space. A cover panel 18 for closing the opening of the cooling chamber 4 is vertically mounted on the upper surface of the condenser 6, and is fixed by an L-shaped bracket 19. A control box 20 for detachably controlling the temperature inside the storage chamber 3 is detachably attached to the front surface of the cover panel 18. A heat insulating material 21 is embedded inside the cover panel 18 as well as the housing 2 (see FIG. 5), and a seal packing 22 is attached to the back surface of the cover panel 18 to secure the sealing property with respect to the cooling chamber 4. (The packing for sealing 22 may be attached to the facing surface on the cooling chamber 4 side). Bolt insertion holes 23 pass through the upper center of the front surface of the cover panel 18 and the L-shaped bracket 19, respectively, and the cover panel 18 can be fixed by screwing the bolts 24 to the opposite surface side of the bulging portion 5. Done. Further, a so-called intercooling type cooler 1 (evaporator) that can be put in and taken out from the cooling chamber 4 is fixed to the back surface of the cover panel 18, and its side surface is covered with cover materials 25a to 25d as shown in FIG. It is surrounded by four sides, but the bottom and top are open to form an air intake and an air outlet (both not shown). Further, the cooler 1 is connected to the compressor 7 side by a connecting hose 26 penetrating the cover panel 18.

On the other hand, as shown in FIG. 3, the cooling chamber 4 is separated from the storage chamber 3 by a partition plate 27. The partition plate 27 separates the air in the storage chamber 3 from the cooling chamber 4. Inflow and outflow openings are provided for circulation between them. A plurality of outflow ports 28 are provided in the region of the lower half of the partition plate 27 as outflow openings. On the other hand, as an inflow opening, the upper edge of the partition plate 27 is provided with a slit-like gap along the depth direction between the ceiling surface of the housing 2 and this, which serves as a cold air inlet 35. Further, a partition plate 30 is horizontally arranged at a height position near the ceiling surface in the storage chamber 3, and a space communicating with the inflow port 35 is secured between the partition plate 30 and the ceiling surface of the housing 2 to introduce cold air. The cold air guide passage 31 is made possible. Although only a part of the partition plate 30 is shown in FIG. 3 in the middle of the partition plate 30, a plurality of cool air drop openings 32 are opened at appropriate intervals to sequentially cool the cool air flowing through the cool air guide passage 31 in the storage chamber 3. I am trying to let it flow down to.

A fan unit 29 is attached to a corner portion of the cooling chamber 4 corresponding to the inflow port 35. The fan unit 29 is composed of a circulation fan 29a for sending the air cooled by the cooler 1 into the storage chamber, and a casing 29b thereof. The casing 29b is screwed at each corner of the partition plate 27 and the ceiling surface of the cooling chamber 4, and covers the inflow port 35 over the entire width (width in the depth direction). Further, inside the cooling chamber 4, a shield plate 33 is interposed between the partition plate 27 and the cooler 1 side as follows, and these are vertically separated from each other with almost no space. A mounting edge 33a is formed in a bent shape on the edge of the shield plate 33 facing the partition plate 27, and is fixed to the partition plate 27 by means such as screwing along the depth direction thereof. However, the fixed position is higher than the region where the outlet 28 is arranged. Then, the shield plate 33 extends obliquely downward from the fixed portion toward the cover member 25a of the cooler 1 which faces the shield plate 33. Further, the shield plate 33 is supported by the support plates 36 interposed between the shield plate 33 and the partition plate 27 at positions on both sides thereof. By mounting the shielding plate 33 in such an inclined manner, the air flowing in from each outlet 28 can be guided to the lower side of the cooler 1.

The lower edge of the shielding plate 33 is bent upward along the entire edge to form a seal edge 34. On the other hand, a rail member 37 is arranged at the lower edge of the cover member 25a of the cooler 1 which faces the rail member 37. The rail member 37 is formed of a mounting edge 37a for the cover member 25a and a guide edge 37b protruding outward and downward in a hook shape from the mounting edge 37a. Has been done. Further, when the rail member 37 is attached, a guide groove 38 into which the above-mentioned seal edge 34 can be inserted is held between the guide edge 37b and the cover member 25a. However, since the groove width of the guide groove 38 is slightly wider than the thickness of the seal edge 34, it does not hinder the smooth insertion of the seal edge 34 when the cooling unit 9 is stored, but the sealability of this portion is effective. The dimensions are set so that Therefore, the shielding plate 33 plays a role of vertically separating the cooler 1 and the partition plate 27, that is, a role of separating the inflow air and the outflow air in a sealed state, and a role of guiding the inflow air. .

Next, the function and effect of this example configured as described above will be specifically described. When performing maintenance work on the cooling unit 9, first, the front panel 17 is removed to expose the cooling unit 9. After that, the bolts 24 that fix the cover panel 18 are loosened to release the tightening on the bulging portion 5, and the screws that fasten the base plate 13 and the screw receiving pieces 10b of the receiving plate 10 are loosened. . By doing so, the cooling unit 9 as a whole can be pulled out from the cooling chamber 4 and the storage space 8, so that maintenance work can be carried out at necessary locations outside the machine. When the maintenance work is completed, the cooling unit 9 is pushed into the cooling chamber 4 and the storage space 8 in the reverse order of the above to be stored. In this case, if the front end of the seal edge 34 is fitted into the guide groove 38 of the rail member 37 and is pushed in as it is, the cooling unit 9 is smoothly stored through the engagement between the guide groove 38 and the seal edge 34. Be done. This ensures that the guide groove 38 and the seal edge 34 are in close contact with each other along the entire edge.

By the way, as described above, the cover panel 18 and the cooler 1 are not assembled orthogonally to each other, or the surface around the opening of the cooling chamber 4 does not face the front accurately. However, the close contact between the guide groove 38 and the seal edge 34 is ensured. In this case, the shielding plate 33, the rail member 37, the cover member 25a, and the like will be deformed such as twisted, so that the above-mentioned error in the assembling can be absorbed. Therefore, the air that has flowed from the storage chamber 3 to the lower side of the shielding plate 33 of the cooling chamber 4 through the outlet 28 is eliminated from the situation in which it mixes with the cool air that has passed through the cooler 1 as in the conventional case, and the cooler 1 is surely performed. Be led to. Therefore, cooling efficiency can be improved.

In addition to the effects described above, the following effects can be expected in this example. That is, in the conventional case, the cooler 1 was supported only by the cover panel 18 in a cantilever manner, but in this example, the cooler 1 is also supported by the partition plate 27 via the shield plate 33 in addition to the cover panel 18. Therefore, it becomes possible to reduce the strength required for the members involved in supporting the cooler 1. Specifically, in terms of cost reduction, such as reduction in plate thickness and screw size. It is expected that it will be a contribution of. Further, when the cooling unit 9 is housed, the cooling unit 9 was not pushed in concentrically with the cooling chamber 4 in the conventional case, and it was often difficult to fit the bolt 24 into the screw hole of the bulging portion 5. On the other hand, in this example, since the pushing operation is guided by the engagement of the seal edge 34 and the guide groove 38, that is, the effect of the positioning with respect to the cover panel 18 is exhibited. It also has the effect of facilitating the fitting operation.

The present invention can be modified in various ways and is not necessarily limited to the above-mentioned embodiments. For example, the relationship between the seal edge 34 and the guide groove 38 may be as shown in FIG. 6 or 7. FIG. 6 shows a second embodiment of the present invention, in which the relationship between the seal edge 34 and the guide groove 38 is reversed from that of the previously described embodiment (first embodiment). That is, the lower edge of the cover member 25a of the cooler 1 is bent outward in a hook shape to integrally form the seal edge 34 along the depth direction, and the seal edge 34 is slidably received. The insertion guide groove 38 is formed by bending the lower edge of the shielding plate 33 upward in a U shape along the depth direction.

The other structure is the same as that of the first embodiment, and the same operational effect can be exhibited. FIG. 7 shows a third embodiment of the present invention. In this embodiment, the lower edge of the cover member 25a extends further downward from the cooler 1, and this portion is used as the sealing edge 34. With the structure thus formed, the same operational effects as those of the first and second embodiments can be obtained. It should be noted that in any of the embodiments, it is possible to attach a seal rubber to the seal edge 34, and by doing so, the sealability can be further enhanced. Further, the cooling chamber can be applied not only to the one arranged laterally of the storage chamber but also to the one arranged vertically. Furthermore, the form of the storage compartment is not limited to any particular one. For example, the storage compartment is not limited to a drawer-type storage compartment, and may be a type having a double door that opens the storage compartment.
