Description

  The present invention relates to an outdoor unit including a compressor and a heat storage device, and an air conditioner including the outdoor unit.

  In this type of conventional air conditioner, it is known to use a heat storage device including a compressor and a heat storage tank that stores heat radiated from the compressor (see, for example, Patent Document 1). Various ideas have been made.

  FIG. 4 shows a conventional heat storage device. As a heat storage tank constituting the heat storage device 101, a metal container having a shape in contact with at least a part of the outer peripheral surface of the compressor 102 is disposed. A gap between the container and the container is filled with a silicon-based resin 104.

Japanese Patent Laid-Open No. 1-8376

  However, when an outdoor unit incorporating the compressor and the heat storage device is subjected to an impact caused by, for example, dropping during transportation or installation, a load is applied to the silicon-based resin filled in the gap between the compressor and the metal container. As a result, peeling occurs between the silicon-based resin and the compressor or between the silicon-based resin and the metal container. In this case, the adhesion between the compressor and the heat storage tank is lowered, and as a result, the heat storage tank may not be able to sufficiently absorb the heat generated by the compressor during operation.

  In addition, when the gap between the compressor and the metal container is not filled with silicon-based resin or the like and the metal container is configured to be detachable from the compressor, when the outdoor unit receives an impact due to dropping, The heat storage tank may be separated from the compressor by the impact force, and as a result, the heat storage tank may not be able to sufficiently absorb the heat generated during operation of the compressor.

  Therefore, the present invention can prevent the heat storage tank from being separated from the compressor by the impact force even when the outdoor unit is impacted by dropping or the like, and the adhesion between the compressor and the heat storage tank can be prevented. It aims at providing the outdoor unit which can suppress a fall and can make a heat storage tank fully absorb the heat which a compressor generate | occur | produces at the time of an operation | movement.

  In order to solve the conventional problems, an outdoor unit of the present invention is in contact with a casing, a compressor housed in the casing and fixed to the casing, and surrounding an outer peripheral surface of the compressor. An outdoor unit equipped with a heat storage tank, which is fixed to the housing and abuts against the upper surface of the heat storage tank to prevent the heat storage tank from coming off the compressor. With tools.

As a result, even if the outdoor unit receives an impact due to dropping or the like, the pop-out prevention tool is in contact with the upper surface of the heat storage tank, so that separation between the compressor and the heat storage tank can be prevented, and the compressor and heat storage A decrease in adhesion between the tanks can be suppressed. As a result, even when the outdoor unit is impacted by dropping or the like, the heat storage tank can sufficiently absorb the heat generated during operation of the compressor.

  The outdoor unit of the present invention can prevent the heat storage tank from being separated from the compressor by the impact force even when the outdoor unit is impacted by dropping or the like, and the adhesion between the compressor and the heat storage tank Can be suppressed, and heat generated by the compressor during operation can be sufficiently absorbed by the heat storage tank.

  A first invention is an outdoor unit characterized in that it is provided with a pop-out prevention tool that is fixed to a housing and abuts against the upper surface of a heat storage tank. However, since the pop-out prevention device prevents the heat storage tank from separating from the compressor due to the impact force, it is possible to suppress a decrease in the adhesion between the compressor and the heat storage tank, and the heat generated by the compressor during operation is reduced. The heat storage tank can be sufficiently absorbed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a diagram illustrating an outdoor unit in the present embodiment.

  The outdoor unit 6 includes a housing 5, a compressor 1, a heat storage device 2 including a heat storage tank 23, an outdoor unit fan (not shown), and a heat storage device 2. In FIG. 1, illustration of the top plate of the housing 5, a part of the side wall of the housing 5, and the outdoor unit fan is omitted for easy understanding.

  The housing 5 includes a bottom plate 51, side walls and a top plate (not shown), and a partition plate 4, a compressor 1, a heat storage device 2, and an outdoor unit fan are housed inside the housing 5.

  As the compressor 1 accommodated in the housing 5, a conventionally known cylindrical one can be used. From the viewpoint of increasing the installation area, the compressor 1 is installed such that its longitudinal direction is vertical.

  A heat storage device 2, which is semi-cylindrical in a cross-sectional view in the axial direction of the compressor 1, is attached to the compressor 1 so as to surround a part of the outer peripheral surface of the compressor 1. A part of the inner peripheral surface of the heat storage device 2 is in close contact with a part of the heat storage device 2. The heat generated by the operation of the compressor 1 propagates to the heat storage device 2, and the heat storage device 2 absorbs this heat and stores it.

From the viewpoint of increasing the installation area efficiency, the heat storage device 2 is installed so that its longitudinal direction is vertical, like the compressor 1.

  This heat storage device can be manufactured by assembling a container body made of resin or the like and then filling a heat storage material such as an ethylene glycol aqueous solution.

  The compressor 1 includes a suction pipe and a discharge pipe (not shown), sucks the refrigerant from the suction pipe, compresses the refrigerant to a predetermined pressure, and discharges the compressed refrigerant from the discharge pipe. In the compressor 1, the temperature rises in the process of compressing the refrigerant, and heat is released to the surroundings.

  In order to improve the heating capacity of the compressor 1, the temperature of the refrigerant is preferably high. Further, the temperature of the compressor 1 needs to be within a predetermined range for operation, but if the operation of the compressor 1 is stopped and left to stand, the temperature of the compressor 1 is necessary to perform the function. When it is lowered to the following and is operated again, it takes time until the temperature of the compressor 1 is increased again to a temperature at which the compressor 1 can be operated.

  In order to improve the heating capacity and shorten the time until the operation is restarted after the operation is stopped, the heat released from the compressor 1 is stored in the heat storage device 2 so that the temperature drop of the compressor 1 is moderated. Therefore, the heat dissipation from the compressor 1 is absorbed and stored by the heat storage device 2. FIG. 2 is an enlarged view of the main part of FIG. 1, FIG. 2A is a diagram illustrating fixing of the heat storage device 2, and FIG.

As shown in FIG. 2 (b), the compressor 1 is fixed to the bottom plate 51 of the housing 5 via a fixture 7. The fixture 7 includes a support plate 71, vibration absorbing rubber 72, bolts 73, and nuts 74.
The compressor 1 and the fixture 7 are fixed by, for example, welding the bottom surface of the compressor 1 and the top surface of the support plate 71 of the fixture 7. An insertion hole is provided in the support plate 71 of the fixture 7. Meanwhile, the bottom plate 51 of the housing 5 is also provided with an insertion hole at a position corresponding to the insertion hole of the support plate 71 of the fixture 7. A cylindrical vibration absorbing rubber 72 is inserted through the insertion hole of the support plate 71 of the fixture 7 and the insertion hole of the bottom plate 51 of the housing 5, and a bolt 73 is inserted into the through hole of the cylindrical vibration absorption rubber. Is inserted, and the support plate 71 of the fixture 7 and the bottom plate 51 of the housing 5 are gently fixed.

  The partition plate 4 is made of resin, for example, and is fixed to the bottom plate 51 and the side wall of the housing 5 with screws or the like so as not to be reliably separated, and restricts the flow of wind by the outdoor unit fan, and at the same time, the outdoor unit fan or the compression unit It also functions as a soundproof plate that blocks the propagation of sound generated by the machine 1.

  Here, the partition plate 4 and the metal pop-out prevention tool 3, for example, are fixed so as not to be reliably separated.

  For this purpose, for example, as shown in FIG. 2A, the attachment piece 31 of the pop-out prevention tool 3 may be fastened to the surface of the partition plate 4 on the compressor 1 side with a screw or the like.

  In this way, in this embodiment, the pop-out prevention device 3 is fixed to the housing 5 via the partition plate 4, but the pop-out prevention device 3 is directly screwed to the housing 5 without using the partition plate 4. For example, it may be fixed securely.

The contact piece 32 of the pop-out prevention tool 3 is in contact with the upper surface 21 of the heat storage device 2. For this reason, even when the outdoor unit 6 receives an impact due to dropping or the like, the pop-out prevention tool 3 prevents the heat storage device 2 from being separated from the compressor 1 by the impact force. Therefore, the fall of the adhesiveness between the compressor 1 and the heat storage apparatus 2 can be suppressed, and the heat generated by the compressor 1 during operation can be sufficiently absorbed by the heat storage apparatus 2.

  In the present embodiment, the heat storage device 2 has a semi-cylindrical shape as viewed in cross section in the axial direction of the compressor 1, but the heat storage device 2 may have a horseshoe shape having an opening. I do not care.

  Further, the outer peripheral surface of the compressor 1 is partially exposed to the outside, and the accumulator 11 is fixed to the compressor 1. The accumulator 11 is normally provided on the refrigerant suction side of the compressor 1, separates the liquid phase refrigerant and the gas phase refrigerant, and supplies the gas phase refrigerant to the compressor 1.

  Here, since the accumulator 11 is fixed to the compressor 1, the center of gravity of the compressor moves to the opening side of the heat storage device 2. However, the pop-out prevention tool 3 includes a locking piece 33 that comes into contact with the inner wall 22 of the heat storage device 2 and effectively prevents the compressor 1 from falling over from the opening of the heat storage device 2 due to vibration or the like. be able to.

  The positional relationship between the accumulator 11, the insertion hole of the fixing tool 7, and the pop-out prevention tool 3 can be arranged as shown in FIGS. 3A and 3B, for example. It can be arbitrarily arranged according to. In addition, in this figure, the thermal storage apparatus 2 is seen through.

  In any case, since the pop-out prevention tool 3 is provided, it is not necessary to fasten the nut to all three bolts, the fixing property is not affected, the safety is not impaired, the assembly is facilitated, and The number of parts can be reduced.

  A pipe for exchanging air with the inside of the compressor is provided at the upper part of the compressor 1, but the pop-out prevention tool 3 is in contact with the inner wall of the heat storage device 2, so that it straddles the upper part of the compressor 1. Therefore, it is not necessary to make contact with the outer surface of the heat storage device 2 of the compressor 1 on the opening side, and interference with piping and motor driving wiring can be prevented.

  In addition, as a manufacturing method of the outdoor unit 6 in this Embodiment, the bottom plate 51 of the housing | casing 5 is prepared first, and the compressor 1 is then attached to the bottom plate 51 of the housing | casing 5 through the fixing tool 7. FIG. . Thereafter, the heat storage device 2 is brought into close contact with the outer peripheral surface of the compressor 1. After that, after attaching the partition plate 4 to the housing 5, the pop-out prevention device 3 is attached to the partition plate 4.

Finally, a side plate is attached to the bottom plate 51 of the housing 5, and a top plate is further attached to the side plate.
The outdoor unit 6 can be manufactured as described above.

  As described above, since the outdoor unit according to the present invention can prevent the heat storage tank from jumping out due to an impact, it can be applied to applications such as a refrigeration cycle apparatus having a heat storage device.
