In the outdoor unit of the housed air conditioner, the electrical box has a support plate that extends on the partition plate with substantially the same width as the partition plate and supports the electrical unit on the machine room side. In a state where the plate is placed on the upper end portion of the partition plate, the one end portion of the support plate can be temporarily fixed to the tube plate of the heat exchanger.
According to this configuration, since the electrical unit is supported on the machine room side of the support plate extending on the partition plate, the amount of protrusion of the electrical box to the heat exchange chamber side can be suppressed. Moreover, since the one end part of the said support plate can be temporarily fixed to the tube plate of a heat exchanger in the state which mounted this support plate in the upper end part of the partition plate, an electrical equipment box can be easily attached to a housing | casing.

  In this configuration, the support plate may include a hole portion that can be hooked on a screw portion provided on the tube plate at one end portion of the support plate. The hole portion may include a small-diameter hole and a large-diameter hole connected to the small-diameter hole, and the small-diameter hole and the large-diameter hole may be provided on substantially the same radius centered on the lower end of the support plate. . Moreover, the said support plate is good also as a structure provided with the tongue piece part extended to the said machine room side from the lower end part of this support plate.

  According to the present invention, since the electrical unit is supported on the machine room side of the support plate extending on the partition plate, the amount of protrusion of the electrical box to the heat exchange chamber side can be suppressed. Moreover, since the one end part of the said support plate can be temporarily fixed to the tube plate of a heat exchanger in the state which mounted this support plate in the upper end part of the partition plate, an electrical equipment box can be easily attached to a housing | casing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The air conditioner according to the present embodiment includes an outdoor unit 10 and an indoor unit (not shown), and performs a cooling operation and a heating operation by flowing a refrigerant through a refrigerant circuit connected by a refrigerant pipe. The outdoor unit 10 is installed outside and exchanges heat with outdoor air to condense the refrigerant during cooling operation and release heat to the outside air, and evaporate the refrigerant during heating operation and take in heat from the outside air. In addition, the directions such as up and down and left and right described below indicate directions when viewed from the front side of the outdoor unit 10 in a state where the outdoor unit 10 is installed.

  FIG. 1 is a view of the outdoor unit 10 as viewed from the front, and FIG. 2 is a view of the outdoor unit 10 as viewed from above. The outdoor unit 10 includes a unit case (housing) 11 having a substantially rectangular parallelepiped box shape. The unit case 11 includes a bottom plate 12, a top plate 13, a front panel 14, and an outer plate 15. The inside of the unit case 11 is a bottom plate. 12 is partitioned vertically by a partition plate 16 provided upright, and is divided into a heat exchange chamber R1 and a machine chamber R2. In the example of FIG. 1, the front panel 14 is removed, but the front panel 14 includes a first front panel 14A and a second front panel 14B that are divided into left and right parts with a partition plate 16 as a boundary. By removing the front panels 14A and 14B, the operator can perform maintenance work on the components in the heat exchange chamber R1 and the machine room R2 from the front side.

  As shown in FIG. 2, the heat exchanger 21 accommodates the heat exchanger 21 on the back side and the blowers 22 </ b> A and 22 </ b> B arranged in the vertical direction on the front side. The heat exchanger 21 is formed by being bent into a substantially L shape when viewed from above, and is disposed along the back surface from the left side surface (outer side surface) of the heat exchange chamber R1. Thus, the heat exchanger 21 forms the left side surface and the back surface of the heat exchange chamber R1 (that is, the unit case 11), and the entire exposed surface from the left side surface to the back surface functions as a ventilation path (suction port). Further, in this configuration, the surface of the heat exchanger 21 is covered with a finger (not shown) made of a resin net or the like in order to prevent a human body or the like from contacting the heat exchanger 21.

The blowers 22A and 22B are attached to a pair of left and right support columns 24L and 24R disposed in the heat exchange chamber R1. These struts 24L and 24R hook the upper ends of the struts 24L and 24R to the upper edge of the heat exchanger 21, respectively, and the lower ends of the struts 24L and 24R are fixed to the bottom plate 12 by screws.
The blower 22A includes a fan motor 26A fixed to the upper part of the support posts 24L and 24R via a base 25A, and a propeller fan (axial fan) 27A attached to the shaft of the fan motor 26A. The propeller fan 27A is disposed close to the front side of the heat exchange chamber R1. Further, the front portion of the propeller fan 27A enters a round flange-shaped fan cover portion 28A provided at the upper portion of the first front panel 14A of the heat exchange chamber R1, and the opening portion of the fan cover portion 28A is ventilated. This opening functions as a path (air outlet), and is covered with a fan guard 29A that prevents the propeller fan 27 from contacting a human body or the like. Further, the blower 22B is disposed below the support posts 24L and 24R and has substantially the same configuration as the blower 22A. Therefore, the blower 22B is assigned the same kind of code as the equipment constituting the blower 22A. The description is omitted.
When the propeller fans 27A and 27B are rotationally driven by the fan motors 26A and 26B, outside air enters the heat exchange chamber R1 around the outdoor unit 10, more specifically, from the back side and the left side of the heat exchanger 21. After being sucked and passed through the substantially front surface of the heat exchanger 21, it is discharged outside through the fan cover portions 28A and 28B on the front surface of the heat exchange chamber R1. That is, the outdoor unit 10 is configured as a front blowing type that blows out air after heat exchange from the front.

Further, as shown in FIG. 1, the machine room R2 includes refrigerant circuit components such as a compressor 31, an accumulator 32, and a valve body such as a four-way valve 33 and an expansion valve (not shown) constituting a part of the refrigerant circuit. Piping is connected and accommodated in a substantially lower space of the machine room R2.
In this configuration, the compressor 31 and the accumulator 32 are provided with a compression container having the same capacity, and are arranged in the machine room R2 in the vertical direction. Specifically, the compressor 31 is installed on the bottom plate 12, and the accumulator 32 is attached to the partition plate 16 above the compressor 31. Thereby, the installation space of the compressor 31 and the accumulator 32 in the machine room R2 can be kept small.
A support piece 36 is disposed at a substantially intermediate position on the front side of the machine room R2, and a gas pipe service valve 37 and a liquid pipe service valve 38 are fixed to the support piece 36. The gas pipe service valve 37 and the liquid pipe service valve 38 are connected to a gas pipe and a liquid pipe (not shown) of unit piping extending from the indoor unit, respectively, thereby constituting a refrigerant circuit for circulating the refrigerant. An electrical box (electrical box) 40 in which various electrical components such as a control board for controlling the air conditioner are disposed is disposed in the upper space of the machine room R2. The electrical box 40 includes a first support plate (support plate) 41 extending above the partition plate 16 and a second support plate 42 attached to the first support plate 41. An electrical unit such as a substrate is disposed on the support plate 41 and the second support plate 42.

As shown in FIG. 3, the partition plate 16 is disposed between the heat exchange chamber R1 and the machine room R2, and separates the heat exchange chamber R1 and the machine room R2 from each other, and the board portion 16A. A front surface portion 16B formed by bending the side edge portion on the front surface side toward the machine room R2, a slope portion 16C formed by obliquely bending the side edge portion on the back surface side of the substrate portion 16A toward the machine chamber R2, and the slope surface. A back surface portion 16D formed by bending the side edge portion of the portion 16C substantially parallel to the front surface portion 16B, an upper surface portion 16E formed by bending the upper edge portion of the substrate portion 16A toward the machine chamber R2, and the upper surface portion ( It is formed in a tray shape with a lower surface portion 16F formed by bending the lower edge portion of the substrate portion 16A to the machine room R2 side substantially in parallel with the upper end portion 16E.
Thus, the partition plate 16 is formed by bending a thin sheet metal into the tray shape, thereby improving the rigidity (strength) of the partition plate 16. Further, in this configuration, in order to further improve the rigidity of the partition plate 16, a reinforcing plate 50 is provided in a part of the partition plate 16, and the accumulator 32 is attached to the partition plate 16 via the reinforcing plate 50. Is attached.

Further, as shown in FIG. 3, the partition plate 16 is erected on the bottom plate 12 by screwing the bottom surface portion 16 </ b> F of the partition plate 16 and the bottom plate 12. Further, although not shown, the back surface portion 16D of the partition plate 16 is fixed to the heat exchanger 21 by screwing. Specifically, as shown in FIG. 2, the heat exchanger 21 includes a tube plate 35 at an end portion on the right side of the heat exchanger 21 in the drawing, and the tube plate 35 includes an inner side of the unit case 11. A rib 35A is formed by bending the edge into a substantially L shape. In this configuration, the back surface portion 16D of the partition plate 16 is screwed to the rib 35A of the tube plate 35 together with the reinforcing plate 50. Thereby, since the partition plate 16 reinforced by the reinforcing plate 50 can be fixed to the tube plate 35, the partition plate 16 can be more firmly supported in the unit case 11, and the vibration of the partition plate 16 can be supported. However, it is difficult to transmit the noise to each panel of the heat exchanger 21 and the unit case 11, and the generation of noise due to this vibration can be suppressed.
Further, since the accumulator 32 is attached to the partition plate 16 via the reinforcing plate 50, the rigidity of the partition plate 16 is increased by the reinforcing plate 50, and the deformation of the partition plate 16 can be prevented by the load of the accumulator 32. The vibration of the partition plate 16 accompanying the vibration of the accumulator 32 can be suppressed.

Next, the electrical box 40 will be described.
As shown in FIG. 4, the electrical box 40 includes a first support plate 41 that extends above the partition plate 16, and a DC that drives the compressor 31 is disposed on the machine chamber R <b> 2 side of the first support plate 41. An inverter board 43 for generating a power supply is arranged. Since the inverter board 43 is a board on which electrical components such as an inverter circuit that generate a relatively large amount of heat are mounted, the inverter board 43 is disposed on the opposite side of the inverter board 43, that is, on the heat exchange chamber R1 side of the first support plate 41. A heat sink 44 for releasing heat generated in the substrate 43 is disposed. The heat sink 44 has a configuration in which metal plates constituting a plurality of fins are arranged with a space left and right.
A cover body 45 that covers the heat sink 44 is disposed on the heat exchange chamber R1 side of the first support plate 41. The cover body 45 is formed by bending a metal plate, and an opening 45 </ b> A through which cooling air for heat exchange with the fins of the heat sink 44 passes is formed in the upper and lower portions.

The first support plate 41 has substantially the same width as the partition plate 16, and is disposed on the upper portion of the partition plate 16, so that the heat exchange chamber R <b> 1 and the machine chamber R <b> 2 cooperate with the partition plate 16. Has the function of sorting. In this configuration, the height of the first support plate 41 is set to be substantially the same as that of the heat exchanger 21 when placed on the partition plate 16.
The first support plate 41 includes a substrate portion 41A on which the inverter substrate 43 and the heat sink 44 are disposed, and a front surface portion 41B formed by bending a side edge portion on the front surface side of the substrate portion 41A toward the machine room R2. A back surface portion (one end portion) 41C formed by bending the side edge portion on the back surface side of the substrate portion 41A substantially parallel to the front surface portion 41B, and an upper surface formed by bending the upper edge portion of the substrate portion 16A to the machine room R2 side. It is formed in a tray shape with a portion 41D and a lower surface portion 41E formed by bending the lower edge portion of the substrate portion 41A to the machine room R2 side substantially parallel to the upper surface portion 41D. Further, in this configuration, the first support plate 41 is formed with a tongue piece portion 41F by bending the edge of the lower surface portion 41E of the first support plate 41 downward.

  As shown in FIG. 4, the tongue piece portion 41 </ b> F extends to the machine chamber R <b> 2 side of the upper end portion of the partition plate 16 when the first support plate 41 is placed on the partition plate 16. The tongue piece portion 41F functions as a positioning guide when the first support plate 41 is placed on the partition plate 16, and also functions as a cover that covers the gap between the first support plate 41 and the partition plate 16. For this reason, even if rainwater enters the machine chamber R2 from the heat exchange chamber R1 through the gap between the partition plate 16 and the first support plate 41, the rainwater hits the tongue portion 41F and flows down below the machine chamber R2. The rainwater does not enter the electrical box 40.

In addition, the electrical box 40 includes a second support plate 42 that is fixed to the first support plate 41 and extends in the width direction of the machine room R2. The second support plate 42 includes a plate portion 42A extending in the width direction of the machine room R2, and a bottom plate portion 42B formed by bending the lower edge portion of the plate portion 42A forward, and the front side of the plate portion 42A. A filter substrate 46 is arranged on the back side, and a reactor 47 is arranged on the back side of the plate portion 42A.
In addition, a cover body 48 that is bent in a substantially U shape in a top view so as to cover the filter substrate 46 is disposed on the front side of the plate portion 42A. The cover body 48 is fixed to the plate portion 42A with screws or the like, and the cover body 48 can be easily detached from the plate portion 42A by removing the screws. On the front surface of the cover body 48, a control board 49 for controlling the operation of various devices disposed in the outdoor unit 10 is disposed. Since the control board 49 is disposed on the front side of the machine room R2, for example, the second front panel 14B (see FIG. 2) can be removed for easy maintenance.
An attachment plate 51 formed by bending a metal plate is fixed to the bottom plate portion 42B of the second support plate 42. On the front side of the attachment plate 51, power is supplied to the outdoor unit 10 or the indoor unit A terminal block 52 is provided for communicating with the terminal.

  As described above, the electrical box 40 includes the first support plate 41 and the second support plate 42, and the inverter substrate 43, the heat sink 44, and the filter substrate as electrical units are provided on the first support plate 41 and the second support plate 42. 46, the reactor 47, the control board 49, a power relay (not shown), a capacitor, and the like are arranged, the weight of the electrical box 40 becomes relatively heavy (for example, about 11 kg), and the mounting work of the electrical box 40 becomes difficult. It was.

For this reason, in this configuration, with the first support plate 41 of the electrical box 40 placed on the upper surface portion of the partition plate 16, the back surface portion 41 </ b> C of the first support plate 41 is attached to the tube plate 35 of the heat exchanger 21. It is configured to be temporarily fixed. Specifically, as shown in FIG. 5, the back surface portion 41 </ b> C of the first support plate 41 has a dharma hole (hole portion) 61 that can be hooked on a screw 62 attached to the rib 35 </ b> A of the tube plate 35. Is formed.
The Dalma hole 61 is formed by connecting a small-diameter hole 61A and a large-diameter hole 61B. The small-diameter hole 61A is larger than the screw diameter of the screw 62. The diameter is smaller than the diameter. The large-diameter hole 61B is larger than the head of the screw 62 and is formed to have a diameter through which the head can penetrate.
Further, in this configuration, the Dharma hole 61 is formed obliquely so that the large diameter hole 61B is located below the small diameter hole 61A on the machine room R2 side. More specifically, the dharma hole 61 is formed on substantially the same radius with the corner 41E1 on the heat exchange chamber R1 side in the lower surface 41E of the first support plate 41 as the center.
Thus, the Dharma hole 61 is formed obliquely so that the large-diameter hole 61B is located below the small-diameter hole 61A on the machine room R2 side. As shown in FIG. 4, the hole 61 </ b> B does not extend further toward the heat exchange chamber R <b> 1 than the rib 35 </ b> A of the tube sheet 35. As a result, the large-diameter hole 61B is blocked by the rib 35A, so that the heat exchange chamber R1 and the machine chamber R2 are prevented from communicating with each other through the large-diameter hole 61B. Rain water or the like is prevented from entering the electrical box 40.

Next, a procedure for attaching the electrical box 40 will be described.
First, the first support plate 41 and the second support plate 42 are combined, and an electrical unit is disposed on the first support plate 41 and the second support plate 42 to form the electrical box 40.
Subsequently, as shown in FIG. 5, the lower surface portion 41E of the first support plate 41 is placed on the upper surface portion 16E of the partition plate 16, and the back surface portion 41C of the first support plate 41 is used with the tongue piece portion 41F as a guide. Is pushed in until it comes into contact with the rib 35A of the tube plate 35 of the heat exchanger 21. In this case, the electrical box 40 can push the electrical box 40 to a predetermined position with a small force by sliding on the upper surface portion 16E of the partition plate 16 using the tongue portion 41F as a guide.
Subsequently, as shown in FIG. 4, the upper portion of the electrical box 40 (for example, the upper surface portion 41 </ b> D of the first support plate 41) is inclined toward the machine room R <b> 1, and the dharma formed on the back surface portion 41 </ b> C of the first support plate 41. The large-diameter hole 61B of the hole 61 is inserted into the head of the screw 62 that is lightly screwed into the rib 35A of the tube plate 35 in advance. As described above, the dharma hole 61 is formed on substantially the same radius with the corner 41E1 on the heat exchange chamber R1 side in the lower surface 41E of the first support plate 41 as the center. When the first support plate 41 (electrical equipment box 40) is rotated in the clockwise direction (X direction in the figure) as the center, the screw 62 moves into the small-diameter hole 61A, and the screw head is inserted into the small-diameter hole 61A. Is caught.
For this reason, the electrical box 40 can be temporarily fixed to the unit case 11, specifically, the partition plate 16 and the tube plate 35 of the heat exchanger 21. Then, the screw 62 is tightened, and the electrical box 40 is fixed to the front side end of the outer plate 15 (FIG. 2) through the screw holes 64 formed in the edges of the second support plate 42 and the mounting plate 51.

Since the Dalma hole 61 that can be hooked on the screw 62 is formed, the electrical box 40 can be temporarily fixed to the partition plate 16 and the tube plate 35 of the heat exchanger 21, so that even an operator can easily mount the electrical box 40. It can be installed in the unit case 11.

According to this embodiment, the inside of the unit case 11 is divided into the heat exchange chamber R1 and the machine room R2 by the partition plate 16, and the heat exchanger 21 and the fans 22A and 22B are accommodated in the heat exchange room R1, and the machine room R2 is accommodated. The electric box 40 accommodates the compressor 31 and the electrical box 40. The electrical box 40 extends on the partition plate 16 with substantially the same width as the partition plate 16, and supports the inverter board 43 on the machine room R2 side. Since the support plate 41 is provided, only the heat sink 44 that cools the inverter board 43 protrudes on the heat exchange chamber R1 side of the first support plate 41, and the amount of protrusion of the electrical box 40 to the heat exchange chamber R1 side is suppressed. be able to. For this reason, the ventilation resistance which arises when the electrical equipment box 40 protrudes in heat exchange chamber R1 is suppressed, and the improvement of the heat exchange efficiency in the heat exchanger 21 can be aimed at.
In particular, in the configuration in which the blowers 22A and 22B are arranged one above the other as in the present embodiment, the flow distribution of the air blown from the blowers 22A and 22B is optimized by suppressing the protruding amount of the electrical box 40. Thus, since the said air blowers 22A and 22B can be arrange | positioned in heat exchange chamber R1, the further improvement of the heat exchange efficiency in the heat exchanger 21 can be aimed at.
In addition, since the first support plate 41 is placed on the upper surface portion 16E of the partition plate 16, the back surface portion 41C of the first support plate 41 can be temporarily fixed to the rib 35A of the tube plate 35 of the heat exchanger 21. The electrical box 40 can be easily mounted in the unit case 11.

  Further, according to the present embodiment, the first support plate 41 includes the Dalma hole 61 in which the screw 62 attached to the rib 35 </ b> A of the tube plate 35 can be hooked on the back surface portion 41 </ b> C of the first support plate 41. Therefore, since the electrical box 40 can be temporarily fixed to the partition plate 16 and the tube plate 35 of the heat exchanger 21, the electrical box 40 can be easily installed in the unit case 11 even by one operator.

  Furthermore, according to the present embodiment, the Dharma hole 61 includes a small-diameter hole 61A and a large-diameter hole 61B, and the small-diameter hole 61A and the large-diameter hole 61B are formed in the lower surface portion 41E of the first support plate 41. Since they are formed on substantially the same radius with the corner 41E1 on the heat exchange chamber R1 side as the center, the first support plate 41 (electrical equipment box 40) is formed in the clockwise direction (the X direction in the figure) around the corner 41E1. ) Can be easily hooked on the dharma hole 61.

Further, according to the present embodiment, the first support plate 41 includes the tongue piece portion 41F that extends from the lower surface portion 41E of the first support plate 41 to the machine chamber R2 side of the upper surface portion 16E of the partition plate 16. When mounting the electrical equipment box 40, the electrical equipment box 40 can be pushed to a predetermined position with a small force by sliding the electrical equipment box 40 on the upper surface portion 16E of the partition plate 16 using the tongue piece portion 41F as a guide. it can.
Furthermore, since it functions as a cover that covers the gap between the first support plate 41 and the partition plate 16, it is assumed that rainwater has entered the machine chamber R2 from the heat exchange chamber R1 through the gap between the partition plate 16 and the first support plate 41. However, since this rainwater hits the tongue piece portion 41F and flows down below the machine room R2, the rainwater is prevented from entering the electrical box 40.
