  The present invention relates to an outdoor unit and a manufacturing method thereof.

  In general, an air conditioner includes an electrical component on which a power element such as an inverter circuit that controls a compressor is mounted. Since the power element generates heat during operation of the air conditioner, various means have been proposed for cooling the power element so that the power element does not reach a temperature higher than the operable temperature.

  For example, Patent Document 1 discloses an outdoor unit that cools an electrical component with a component in which a refrigerant pipe through which a refrigerant flows and a heat radiation fin are joined. In the outdoor unit of Patent Document 1, a part of the partition plate 11a extends in the horizontal direction from the partition plate 11 arranged in the vertical direction that partitions the machine room and the heat exchange chamber. The electrical component module 10 is fixed to the lower surface of a part 11a of the partition plate by screwing a screw from below. Furthermore, the component which joined the radiation fin 10a and the refrigerant | coolant piping 20a is being fixed to the lower surface of the electrical component module 10 by screwing a screw from below. In this outdoor unit, a part in which the heat radiating fins 10a and the refrigerant pipe 20a are joined is prepared in advance and assembled at a position where the electrical component module is disposed, and then the electrical component module is set at the disposed position.

The back side stopper 88 is bent from the tip of the guide portion 85d and extends in a substantially horizontal direction, and has a substantially vertical inner wall surface.

  Next, the manufacturing method of the outdoor unit 11 of this embodiment is demonstrated.

  First, as shown to Fig.10 (a), the partition plate 39, the structure of a refrigerant circuit, etc. are arrange | positioned on the baseplate 30a as a base. Examples of components of the refrigerant circuit 18 include an outdoor heat exchanger 25, a compressor 23, an oil separator 24, an expansion valve 26, an accumulator 27, a four-way switching valve 28, and a cooling member 100. At this time, the electrical component module 35 is not yet disposed on the bottom plate 30a.

  In a state before the electrical component module 35 is disposed on the bottom plate 30a, a space of a predetermined size is provided at the planned placement position M of the electrical component module 35, and the refrigerant is located on the front side of this space. A jacket 37 and a refrigerant pipe 18a are arranged. The position of the refrigerant jacket 37 before the electric component module 35 is arranged is such that the surface of the refrigerant jacket 37 is the heat transfer of the electric component module 35 when the electric component module 35 is arranged at a predetermined arrangement position. The position is adjusted so as to be in surface contact with the front surface 60a of the plate 60 or in the vicinity thereof.

  Next, as shown in FIGS. 13A to 13C, the electrical component module 35 is moved from the separation position to a predetermined arrangement planned position M. FIG. 13A is a perspective view showing a state in which the electrical component module 35 is in the separated position, and FIG. 13B is a perspective view showing a state in which the electrical component module 35 is in the relay position. ) Is a perspective view showing a state in which the electrical component module 35 is in the arrangement position (arrangement planned position M).

  This arrangement process includes the following two stages. In the first stage, by sliding the first engagement member 71 from the near side to the far side in a state where the first engagement member 71 is engaged with the lateral portion 85 of the second engagement member 81, The electrical component module 35 is moved from the separation position to the relay position. In the second stage, with the first engagement member 71 engaged with the vertical portion 83 of the second engagement member 81, the first engagement member 71 is slid from above to below, and the electrical component module 35. Is moved from the relay position to the planned placement position M.

  The separation position in the present embodiment is a position closer to the front side (front side) than the relay position, and when the first engagement member 71 is engaged with the lateral portion 85 of the second engagement member 81, that is, the first position. This is the position of the electrical component module 35 when the engaging portions 71 d and 71 e of the first engaging member 71 are placed on the placement path 85 d of the lateral portion 85.

  In the first stage, as shown in FIG. 12A, first, the lower ends of the engaging portions 71 d and 71 e of the first engaging member 71 are placed on the upper surface of the placing path 85 d of the lateral portion 85. In the present embodiment, as described above, the first gripping portion 43, the reactor 94, and the first engagement member 71 are arranged so that their relative positions are close to each other. The distance between 43 and the first engaging member 71 is reduced. Thereby, since the electrical component module 35 can be accurately positioned in a state where the first grip portion 43 is gripped, the lower end portions of the engagement portions 71d and 71e are placed on the upper surface of the placement path 85d. Improved workability.

  Next, in this state, the electrical component module 35 is pushed from the near side toward the far side. At this time, the first engagement member 71 slides back along the lateral portion 85. During the sliding movement of the electrical component module 35, the lower ends of the engaging portions 71d and 71e are in contact with or close to the mounting path 85d of the lateral portion 85. The side wall 85c of the horizontal portion 85 restricts the movement of the lower end portions of the engaging portions 71d and 71e in the left-right direction to some extent during the sliding movement, and prevents the engaging portions 71d and 71e from coming off from the placement path 85d. it can.

  After the engagement portion 71e on the back side exceeds the back end portion of the placement path 85b due to the slide movement, the engagement portion 71e is placed along the guide wall 85d, and only the engagement portion 71d on the near side is placed. The first engagement member 71 is further moved to the back side while being placed on the placement path 85d. Then, after the front engaging portion 71d also exceeds the rear end of the mounting path 85b, the first engaging member 71 is moved with the engaging portions 71d and 71e both along the guide wall 85d. When it is further moved to the back side, the back side engaging portion 71e comes into contact with the back side stopper 88, and the electrical component module 35 is restricted from sliding further to the back side (see FIG. 12B). ). This restriction position is directly above the upper end portion of the vertical portion 83.

  Further, when the first engaging member 71 is moved to the back side with the engaging portions 71d and 71e being along the guide wall 85d, the upper stopper 86 restricts the upward movement of the engaging portions 71d and 71e. Therefore, the 1st engagement member 71 can be moved to the back side further stably.

  In the second stage, first, the lower end portions of the engaging portions 71d and 71e in each first engaging member 71 are inserted into the groove portions 83f and 83g from the upper end of the vertical portion 83, respectively, and the first engaging members 71 are respectively inserted in the vertical portions. Engage with the part 83. At this time, since the corner portion 83h is provided in the engaging portion 83c, even if the positions of the lower end portions of the engaging portions 71d and 71e are slightly shifted, the corner portion 83h causes the engaging portions 71d and 71e to move into the groove portions 83f and 83g. Play the role of guiding to the side. Thus, the engaging portions 71d and 71e are easily inserted into the groove portions 83f and 83g.

  Next, in the state of being inserted in this way, the first engagement members 71 are slid downward to move the electrical component module 35 downward (see FIG. 12C). The electrical component module 35 stops when the leg portions 71b and 71c of the first engaging members 71 come into contact with the horizontal portion 83e of the vertical portion 83, and is disposed at a predetermined position as shown in FIG. Is done.

  Next, as shown in FIG. 14A, the refrigerant jacket 37 is fixed to the heat transfer plate 60 with a bolt B1 as a fixing means. Finally, the terminal block 46 is rotated around the bolt B so that the refrigerant jacket 37 and the refrigerant pipe 18 a are covered with the terminal block 46.

  In the case of removing the electrical component module 35 from the installation position at the time of maintenance, parts replacement, etc., for example, the following may be performed. First, the terminal block 46 is rotated from the closed state in which the refrigerant jacket 37 is covered by the terminal block 46 (FIG. 14B) to open the terminal block 46 (FIG. 14A). Next, the bolt B1 that fixes the refrigerant jacket 37 to the heat transfer plate 60 is removed.

  Next, the first engagement member 71 is slid upward along the vertical portion 71 (FIG. 12C), and the upper end portions of the inclined portions 71f and 71g of the first engagement member 71 contact the upper stopper 86. The electrical component module 35 is moved from the installation position to the relay position by stopping the upward sliding movement at the contact (FIG. 13B). When the first engaging member 71 is slid upward with respect to the vertical portion 71 in this way, the upper portions of the first engaging member 71 are the lower ends of the horizontal portions 85 by providing the inclined portions 71f and 71g. It is possible to suppress a step between the partition plate 39 and the partition plate 39. Thereby, the 1st engagement member 71 can be slid stably. At this relay position, the first engagement member 71 is disengaged from the vertical portion 71 (FIG. 12B).

  Next, the electrical component module 35 is moved to the near side with the upper end portions of the inclined portions 71f and 71g abutting or approaching the upper stopper 86 and the engaging portions 71d and 71e abutting or approaching the fixing portion 85a. Let If it moves to some extent, the lower end part of engaging part 71d, 71e will be mounted on the mounting path 85d. In this state, the first engagement member 71 is further slid along the lateral portion 85 to move the electrical component module 35 to the separation position. Thereby, the electrical component module 35 can be safely removed from the arrangement position.

  Here, the operation | movement operation | movement of the air conditioning apparatus 10 of this embodiment is demonstrated.

  In the air conditioner 10, when the cooling operation is performed, the four-way switching valve 28 is switched to the first state. The refrigerant compressed by the compressor 23 is separated by the oil separator 24 and then flows into the outdoor heat exchanger 25 via the four-way switching valve 28. This refrigerant is condensed by exchanging heat with outdoor air in the outdoor heat exchanger 25 and becomes a liquid refrigerant. The liquid refrigerant flows upward in one pipe 18 b extending in the vertical direction, and then flows through the refrigerant pipe 18 a fixed to the refrigerant jacket 37. At this time, if the power element 56a generates heat by driving the compressor 23 and the fan motor, the heat transfer plate 60 is heated by the heat generated by the power element 56a. However, the heating element 60a is heated by the refrigerant flowing through the refrigerant pipe 18a. The heat transfer plate 60 is cooled via the refrigerant jacket 37.

  The refrigerant that has flowed through the refrigerant pipe 18 a flows downward through the other pipe 18 b that extends in the vertical direction, and then is decompressed by the expansion valve 26 and flows into the indoor heat exchanger 20. This refrigerant is vaporized by exchanging heat with indoor air in the indoor heat exchanger 20. The indoor air is cooled and blown into the room by this heat exchange. The refrigerant heated and evaporated by the room air flows into the accumulator 27 via the four-way switching valve 28. In the accumulator 27, the refrigerant is gas-liquid separated, and the gas refrigerant separated here is sucked into the compressor 23. During the cooling operation, the refrigerant circulation is continuously performed.

  On the other hand, during the heating operation, the four-way switching valve 28 is switched to the second state. The refrigerant discharged from the compressor 23 is introduced into the indoor heat exchanger 20 via the oil separator 24 and the four-way switching valve 28. In the indoor heat exchanger 20, the refrigerant is condensed by exchanging heat with room air. By this heat exchange, the room air is heated and blown into the room. The refrigerant cooled and condensed by the indoor air is expanded by the expansion valve 26, and then flows upward through one pipe 18 b extending in the vertical direction, and then flows through the refrigerant pipe 18 a fixed to the refrigerant jacket 37. At this time, the heat transfer plate 60 heated by the heat generated by the power element 56a is cooled.

  The refrigerant that has flowed through the refrigerant pipe 18 a flows downward through the other pipe 18 b extending in the vertical direction, is then introduced into the outdoor heat exchanger 25, evaporates, and passes through the four-way switching valve 28 to the accumulator 27. Inflow. The gas refrigerant separated here is sucked into the compressor 23. This refrigerant circulation is continuously performed during the heating operation.

  As described above, in the present embodiment, the electrical component module 35 is provided with the first engagement member 71, and the casing 30 or the support body 39 is provided with the second engagement member 81. The electrical component module 35 can be guided between the distant position and the disposition position by engaging the second engaging member 81 and sliding the 71. Accordingly, since the electrical component module 35 can be moved between the separation position and the disposition position through a preset route, the electrical component module 35 is connected to the refrigerant circuit such as a refrigerant pipe when the electrical component module 35 is attached or removed. It can suppress colliding with a structure. Thereby, the electrical component module 35 can be safely attached and detached.

  In the present embodiment, when the electrical component module 35 is attached, the electrical component module 35 is moved to the installation position side by sliding the first engagement member 71 from the upper side to the lower side along the vertical portion 83. be able to. As a result, the electrical component module 35 can be slid using its own weight, so that the load can be reduced in the case of manual work by an operator, and the power consumption can be reduced in the case of work by a machine. You can save.

  In the present embodiment, since the second engagement member 81 further has a lateral portion 85, the first engagement member 71 is slid along the lateral portion 85 to the far side, so that the first engagement member 71 is moved. The joint member 71 can be safely and accurately moved to the relay position where the joint member 71 is relayed from the horizontal portion 85 to the vertical portion 83.

  Further, in the present embodiment, the first engagement member 71 can be stopped at the relay position by the back side stopper 88 during the slide movement along the lateral portion 85, so the first engagement member 71 goes too far back. Thus, the first engagement member 71 can be accurately moved to the relay position. Thereby, since it can suppress that the electrical component module 35 collides with the other components in the back | inner side, the electrical component module 35 can be attached or removed more safely.

  In the present embodiment, the first engagement member 71 can be stopped at the relay position by the upper stopper 86 during the upward sliding movement along the vertical portion 83, so that the first engagement member 71 goes upward. It is possible to accurately move the first engagement member 71 to the relay position while suppressing the excess. Thereby, since it can suppress that the electrical component module 35 collides with the other components which are upwards, the electrical component module 35 can be arrange | positioned more safely.

  Further, in the present embodiment, since the horizontal portion 85 is arranged in a substantially horizontal direction, the first engagement member 71 is slid to the back side along the horizontal portion 85, and the detachment is slid to the front side.
