[0002]
[Prior art]
An undercounter type cooling storage (storage) in which a main body that internally defines a storage room for storing foods and the like, and a unit storage part for storing a cooling unit (air conditioning unit) for cooling the storage room are arranged horizontally adjacent to each other. However, it is preferably used in the field for business use. For example, as shown in FIG. 11, the main body 12 in the cooling storage 10 is provided with a unit storage portion 14 adjacent to the main body 12, and a horizontal top plate 16 is disposed on the upper surface of both of them. It functions as a counter. The main body 12 is formed in a horizontally long box shape with openings 12a and 12a (partially shown in FIG. 12) formed in the front portion thereof, and a storage chamber 12b for storing a storage object such as food is defined in the inside thereof. Made. Further, on the front surface of the main body 12, for example, double-spread type heat insulating doors 18 and 18 are disposed so as to be openable and closable, and the openings 12 a and 12 a are opened and closed by the doors 18 and 18.
[0003]
The unit storage section 14 is formed in a box shape by a side plate, a back plate, a bottom plate, the top plate 16 and the like, and a machine room for storing therein a cooling unit (not shown) for cooling the storage chamber 12b. 14a is defined. The cooling unit includes a compressor, a condenser, a cooler, and the like. These cooling units are configured to be able to be pulled out from the machine chamber 14a through a front opening 14b formed in the front portion of the unit storage portion 14. The The front opening 14b of the unit storage section 14 is opened and closed by a front panel 20 that is rotatably disposed on the front surface of the storage section 14.
[0004]
[Problems to be solved by the invention]
The front panel 20 is rotatably disposed via a pair of vertically spaced hinges 22 and 22 disposed on a partition wall of the main body 12 that partitions the storage chamber 12b and the machine chamber 14a. When opening the opening 14b, the hinges 22 and 22 are used as fulcrums to rotate toward the front side of the main body.
[0005]
In the open state of the front panel 20, as shown in FIG. 12, the front surface of the main body 12 and the front panel 20 overlap, so that a space overlapping the unit storage portion side on the front surface of the main body 12 must be secured. That is, the width dimension of the heat insulating door 18 disposed on the front surface of the main body 12 should be shortened so as not to interfere with the front panel 20, and the opening dimension of the opening 12a of the main body 12 should be correspondingly reduced. In addition, it becomes difficult to take in and out the storage object from the opening 12a. In addition, in order to reduce the opening size of the opening 12a, a dead space S is generated at the front corner of the storage chamber 12b, and the effective storage volume capable of storing an object to be stored is reduced. Etc. are likely to accumulate, and problems with poor cleaning properties are pointed out.
[0006]
In addition, if the pivot position of the front panel 20 is set in the unit housing part 14 on the side opposite to the main body side, the front panel 20 will not overlap with the front surface of the main body when the front panel 20 is opened. It is possible to eliminate problems such as However, in this case, if the unit storage unit 14 is installed in close contact with the wall surface of the kitchen, a sufficient rotation space of the front panel 20 cannot be secured, and it becomes an obstacle to pulling out the cooling unit even when the front panel 20 is fully opened. . Therefore, when pulling out the cooling unit from the machine room 14a for maintenance, a complicated operation of removing the front panel 20 is required. Conversely, if a gap is formed between the unit housing portion 14 and the wall surface in order to ensure a sufficient space for rotating the front panel 20, there will be a problem that effective use of the space in the narrow kitchen cannot be achieved.
[0007]

A cooling storage 10 as a storage shown in FIG. 1 includes a storage room 12b for cooling and storing an object to be stored such as food, in a box-shaped main body 12 formed in a horizontally long shape. On the front side, corresponding to the plurality of openings 12a opened in the front part of the main body 12, heat insulating doors 18 are provided for closing the openings 12a so as to be openable and closable. The heat insulating door 18 disposed on the left side of the front surface of the main body (unit storage portion side) is pivotally attached to a pair of upper and lower hinge members 24 (only one is shown in FIG. 3) disposed on the left side of the front surface of the main body 12. ing. The top plate 16 disposed on the upper surface of the main body 12 also serves as a cooking table and extends to the left side of the main body by a predetermined length.
[0011]
On one side of the main body 12 (left side in FIG. 1), a unit storage portion 14 that internally defines an adjacent machine chamber 14a across the storage chamber 12b and the partition wall 25 is disposed adjacently. The unit storage portion 14 is formed in a box shape by arranging a side plate, a back plate, and a bottom plate on a rectangular frame, and a top plate 16 extending from the main body 12 on the top. In addition, a front opening 14b is formed in the front part. Further, as shown in FIG. 3, a cooling box 26 communicating with the storage chamber 12 b through an opening 25 a formed in the partition wall 25 is disposed above the inside of the unit storage portion 14. In the cooling box 26, a cooler 28 and an internal fan 30 (to be described later) that function to cool the interior of the storage chamber 12b are accommodated.
[0012]
The machine room 14a includes a cooler 28, a refrigeration mechanism 32, and the like, and a cooling unit (air conditioning unit) 34 for cooling the storage room 12b is accommodated in such a manner that it can be pulled out through the front opening 14b. (See FIG. 2). That is, as shown in FIG. 3, a condenser 38, a condensing fan 40, and a compressor 42 constituting the refrigeration mechanism 32 are placed on the moving base 36 accommodated in the machine room 14a so as to be movable back and forth from the front side of the machine room 14a. They are arranged in order toward the rear side. On the right side (main body side) of the condenser 38, a heat insulating lid 44 that closes an opening 26a formed on the front side of the cooling box 26 is fixed via a bracket 46, and on the back side of the heat insulating lid 44.

Yes. When the internal fan 30 is rotated, the storage room air sucked into the inside of the cooling box 26 from the opening 25a of the partition wall 25 flows into the casing 48 from below and moves the cooler 28 upward from below. The cool air is cooled in the process of moving to the inside, and this cool air is blown from the internal fan 30 to the storage chamber 12b and circulates. In this case, the cooler 28 and the internal fan 30 are not arranged so as to overlap each other in the horizontal direction, but are arranged in a vertical relationship so that the air flowing from the lower side to the upper side in the casing is cooled by the cooler 28. It is configured so that efficient heat exchange can be performed.

Moreover, the heat-proof part 52b and the drip-proof part 52c are set to the dimension which can cover the substantially full length of the glass tube heater 50, and the thermal influence to the to-be-stored object in the storage chamber 12b by the glass tube heater 50 heated in the defrost operation is carried out. Is prevented by the heat-proof portion 52b, and the drip-proof portion 52c prevents dew dripping from the cooler 28 from being applied to the glass tube heater 50. In addition, a notch 52d having a required dimension is formed at the inclined upper end portion of the drip-proof portion 52c at a position separated from the upper side of the glass tube heater 50 so as to communicate vertically. That is, while preventing the flow of cold air from being disturbed by the drip-proof portion 52c during the cooling operation, it is possible to prevent heat from being accumulated in the connecting portion between the heat-proof portion 52b and the drip-proof portion 52c during the defrosting operation. The defrosting efficiency can be improved.
[0015]
An electrical equipment box 54 that houses a microcomputer board for controlling the operation of the cooling storage 10, a temperature setting switch, a power switch, and the like is disposed on the front upper portion of the heat insulating lid 44. As shown in FIG. 4, an upper male hinge 56 is disposed at the upper portion of the side surface facing the main body side in the electrical box 54. Further, a lower male hinge 58 aligned with the upper male hinge 56 in an up-and-down relationship is disposed on the moving base 36 located below the electrical box 54 via a mounting plate 60, and the front opening of the unit storage portion 14 is arranged. The front panel 62 that opens and closes the portion 14b is configured to be rotatably disposed on the male and female hinges 56 and 58.
[0016]
The front panel 62 has a female hinge 64 that can be attached to and detached from the upper and lower male hinges 56 and 58 at a vertically spaced position on the right end (end on the main body side) of the rear surface (the surface facing the machine room). 64, and the female hinges 64 and 64 are pivotally attached to the male hinges 56 and 58, so that the front panel 62 is rotatably disposed on the cooling unit 34. Further, as shown in FIG. 6, the right end of the front panel 62 extends a predetermined length from the right end of the electrical box 54 to the main body side, and the left side surface of the electrical box 54 and the mounting plate 60 facing the main body 12. A gap G having a predetermined width that allows the right extending portion 62a of the front panel 62 to rotate is defined between them. Further, in a state in which the front opening 14b is closed by the front panel 62, the rear surface thereof is set to be positioned in front of the front surface of the main body 12, and thereby the front opening 14b including the gap G is substantially entirely covered. Can be closed.
[0017]
Further, as shown in FIG. 6, the right vertical side surface (vertical side surface on the pivot side) of the front panel 62 is separated from the main body side (closer to the other vertical side surface) as it goes from the back side to the front side. The right extension 62a is prevented from interfering with the main body 12 and the heat insulating door 18 when the panel 62 is opened and closed, and can be prevented from interfering with the front panel 62 when the heat insulating door 18 is opened and closed. (See FIGS. 9 and 10).
[0018]
[Effect of the embodiment]
Next, the operation of the front panel mounting structure according to the embodiment will be described below. With the cooling unit 34 stored in the machine room 14a, the front opening 14b of the unit storage unit 14 is closed by the front panel 62 and the cooler 28 is mounted in the cooling box 26 as shown in FIG. Stored. When the operation of the cooling unit 34 is started in this state, the refrigerant is circulated and supplied from the refrigeration mechanism 32 to the cooler 28 to cool the cooler 28. Further, the internal fan 30 rotates, and the air on the bottom side in the storage chamber 12b is sucked into the lower side of the cooling box 26 through the opening 25a of the partition wall 25 as shown in FIG. This air flows into the casing 48 from below and exchanges heat with the cooler 28, and then is blown into the storage chamber 12b through the internal fan 30 at the upper portion thereof, whereby the storage chamber The inside of 12b is cooled. In this case, since the internal fan 30 is positioned above the cooler 28, the air flowing through the casing 48 passes through the entire cooler 28, and efficient air cooling is achieved. In addition, since a drip-proof portion 52c that covers the upper portion of the glass tube heater 50 in the cover 52 disposed in the lower portion of the cooler 28 is formed with a notch 52d that communicates with the top and bottom, air is passed through the notch 52d. Flows to the cooler 28 side. That is, it is suppressed that cooling efficiency falls because the air flow is inhibited by the cover 52. In addition, since efficient heat exchange in the cooler 28 is possible, the same capability can be expected even if a small cooler 28 is used. In this case, the space in the machine room can be effectively used. Become.
[0019]
Next, when the defrosting operation is started, energization of the glass tube heater 50 is started, and the cooler 28 is heated by the heater 50 to melt the frost, thereby achieving defrosting. In this case, dew dripping from the cooler 28 is prevented from being directly applied to the glass tube heater 50 by the drip-proof portion 52 c of the cover 52. Moreover, since the heat-insulating part 52b faces between the glass tube heater 50 and the storage chamber 12b, the heat of the heater 50 is suppressed from entering the storage chamber 12b, thereby preventing the thermal effect of the storage object. Can do. Furthermore, since the notch 52d is formed in the continuous portion between the heat-proof portion 52b and the drip-proof portion 52c, the heat of the glass tube heater 50 does not accumulate in the continuous portion, and the cooler 28 is efficiently provided. The defrosting efficiency can be improved. In addition, since the notch 52d is separated from the upper side of the glass tube heater 50, the dew dropped from the cooler 28 is not applied to the heater 50 via the notch 52d.
[0020]
When inspecting the cooling unit 34, the front panel 62 is rotated to the main body side with hinges 56, 58, 64, 64 as fulcrums to open the front opening 14b. In this case, the front panel 62 is rotatably disposed on the cooling unit 34 and a gap G that can accommodate the right extension 62 a of the panel 62 is provided between the electrical box 54, the mounting plate 60 and the main body 12. Therefore, when the front panel 62 is fully opened, there is almost no overlap with the front surface of the main body. That is, it is not necessary to provide a space for overlapping with the front panel 62 on the main body 12 side, whereby the width dimension of the heat insulating door 18 can be set large, and the opening dimension of the opening 12a can be set large, so Things can be easily taken in and out, dead space S does not occur at the front corner of the storage chamber 12b, and the effective storage capacity increases. Further, it is possible to eliminate the accumulation of dust or the like in the dead space S and the deterioration of the cleaning performance.
[0021]
Further, in the embodiment, since the inclined surface 62b is formed on the right vertical side surface of the front panel 62, the projecting dimension from the pivotally attached portion to the main body side of the panel front corner portion is reduced. . That is, as shown by an imaginary line in FIG. 9, the front panel 62 can be fully opened without interfering with the heat insulating door 18, and as shown by an imaginary line in FIG. 10, the heat insulating door 18 interferes with the front panel 62. It can also be fully opened without letting it go. And the dimension of the heat insulation door 18 and the opening part 12a can be set still larger by the said inclined surface 62b. Furthermore, since the front side opening 14b is closed by the front panel 62 and the back surface thereof is set to be positioned in front of the front surface of the main body 12, the right extension from the pivoting portion of the front panel 62 to the main body side is set. The protruding portion 62a can be extended and its end can be brought closer to the main body side. That is, it is possible to bring the rotation path of the end of the right extension 62a closer to the main body as long as it does not interfere with the main body 12, so that the front opening 14b including the gap G can be closed almost entirely. It becomes like this.
[0022]
Since the pivoting portion of the front panel 62 is on the main body side, the left end surface (the surface opposite to the main body side) of the unit storage portion 14 can be brought into close contact with the wall surface of the kitchen. Can be used effectively. Further, since the front panel 62 of the embodiment is disposed in the cooling unit 34 housed in the unit housing portion 14, the cooling unit 34 is pulled out from the machine room 14a without opening the front panel 62. It is possible.
[0023]
In the cooling unit 34 of the embodiment, since the cooler 28 is disposed on the side of the condenser 38, the height dimension of the entire unit can be kept small, thereby reducing the height dimension of the cooling storage itself. Is possible. In addition, by suppressing the height of the cooling unit 34 to be small, the strength of the unit itself can be improved and stabilization can be achieved.
[0024]
In addition, although the Example demonstrated the case where the to-be-stored object was cooled as a store, you may heat a to-be-stored object. Further, the front panel may adopt a configuration in which the front panel is pivotally attached to other members constituting the cooling unit (air conditioning unit) instead of the electrical box and the mounting plate as in the embodiment.
[0025]
【The invention's effect】
As described above, according to the front panel mounting structure of the storage according to the present invention, since the front panel is rotatably disposed in the air conditioning unit stored in the unit storage unit, the unit storage unit is closely attached to the wall surface of the kitchen. This makes it possible to effectively use the space in a narrow kitchen. In addition, even when the front panel pivot part is on the main body side, it can be configured not to overlap the front surface of the main body when the panel is opened. This makes it possible to increase the size of the storage object, facilitates the taking in and out of the storage object, and prevents the occurrence of dead space in the main body. Therefore, the effective storage volume can be increased and the cleaning property can be improved.
[0026]
In addition, with the front opening closed by the front panel, the machine room side surface is set to be located in front of the front of the main unit, so that the front side can be moved without interfering with the main unit when the front panel is opened or closed. It may be possible to close the opening substantially entirely. In addition, since the inclined surface is formed on the vertical side surface of the front panel on the pivoting side, it is possible to bring the end of the pivoting side of the panel closer to the main body side and cover the front side between the main body and the unit storage portion. be able to.
