Description

Outdoor unit of air conditioning unit

technical field

The invention relates to an outdoor unit of an air conditioner.

Background technique

It is generally known that a frame is divided into a heat exchange chamber and a mechanical chamber by a partition, a heat exchanger and a blower are accommodated in the heat exchange chamber, and a compressor, an electrical installation box (electrical box) and a liquid accumulator are accommodated in the mechanical chamber. The outdoor unit of the air conditioning unit. In recent years, in order to try to realize the miniaturization of the machine room, a scheme in which a compressor and an accumulator are arranged up and down in the machine room, and the accumulator is mounted on a bulkhead has been proposed (for example, refer to Japanese Patent Application Laid-Open No. Publication No. 09-243115). It is also proposed that the electrical installation box is arranged substantially horizontally on the partition plate, and one end of the electrical installation box protrudes toward the heat exchange chamber side, and the outdoor unit of the electrical installation box is cooled by the air passing through the heat exchange chamber (for example, refer to Japanese Patent Laid-Open No. 2001-201110).

Among such outdoor units, there is also known an air conditioner in which a heat exchanger in which a plurality of fin-tube heat exchange parts are laminated in the thickness direction and is bent so as to form a stepped part on one end side is installed in the casing. An outdoor unit (for example, refer to Japanese Patent Application Laid-Open No. 2002-250544).

In the structure in which the accumulator is installed on the separator, since the accumulator is relatively heavy (for example, 8 kg), the separator is required to have strength not to be deformed by the weight of the accumulator. In addition, since the vibration generated during the operation of the compressor is transmitted to the accumulator through the piping, it is necessary to consider the vibration of the diaphragm caused by the vibration. It should also be considered that if the partition plate vibrates, the panel connected to the partition plate and constituting the frame will also vibrate accordingly, resulting in noise from the outdoor unit. In view of this, in the prior art, an elastic member is provided between the separator and the accumulator, so there is a problem that the structure for mounting the accumulator on the separator becomes complicated. In addition, if one end of the electrical installation box protrudes toward the heat exchange chamber, these protruding parts will block the air supply and reduce the heat exchange efficiency of the heat exchanger. Therefore, it is desirable to control the amount of protrusion when installing the electrical installation box. . On the other hand, however, if the protrusion amount of the electrical component box is reduced and the electrical component box is placed on the side of the heat exchange chamber, there is a problem that it becomes difficult to attach the electrical component box to the housing.

Furthermore, in the conventional structure, the heat exchanger forms a part of the side surface of the housing, the tube sheet is provided on the heat exchange part arranged outside, and the front panel of the housing is attached to the tube sheet. Therefore, outside air does not flow smoothly at the stepped portion of the heat exchanger, and the stepped portion does not contribute to heat exchange, so there is a problem that the heat exchange efficiency of the heat exchanger is low.

The air conditioner according to the embodiment of the present invention is composed of an outdoor unit 10 and an indoor unit (not shown), and a refrigerant flows through a refrigeration circuit connected by refrigerant piping to perform cooling operation and heating operation. The outdoor unit 10 is installed outdoors to exchange heat with the outdoor air. When performing cooling operation, the refrigerant condenses and releases heat to the outside; when performing heating operation, the refrigerant evaporates and absorbs heat from the outside. . The up-down direction and the left-right direction described below are directions viewed from the front in a state where the outdoor unit 10 is installed.

FIG. 1 is a view of the outdoor unit 10 viewed from the front, and FIG. 2 is a view of the outdoor unit 10 viewed from above. The outdoor unit 10 has a unit housing (frame) 11 in the shape of a substantially rectangular parallelepiped box. The unit housing 11 has a bottom plate 12, a top plate 13, a front panel 14 and an outer plate 15. The partition plate 16 on the top is separated longitudinally, and is divided into a heat exchange chamber R1 and a mechanical chamber R2. In addition, in the embodiment of FIG. 1 , the state in which the front panel 14 is detached is shown, and the front panel 14 is composed of a first front panel 14A and a second front panel 14B that are divided into two with the partition plate 16 as a boundary. By removing the respective front panels 14A, 14B, the operator can perform maintenance operations on the parts in the heat exchange chamber R1 and the machine chamber R2 from the front.

As shown in FIG. 2 , in heat exchange chamber R1 , heat exchanger 21 is accommodated on the back side of heat exchange chamber R1 , and blowers 22A, 22B arranged vertically are accommodated on the front side. The heat exchanger 21 is bent in a substantially L-shape when viewed from above, and is arranged along the rear surface from the left side (outer side) of the heat exchange chamber R1. Thus, the heat exchanger 21 forms the left side and the back of the heat exchange chamber R1 (that is, the unit casing 11 ), and the entire exposed surface from the left side to the back functions as a ventilation path (intake port). In this structure, in order to prevent the human body etc. from coming into contact with the heat exchanger 21, the surface of the heat exchanger 21 is covered with a fin guard (not shown) made of a resin mesh or the like.

Blowers 22A, 22B are attached to a pair of right and left columns 24L, 24R provided in heat exchange chamber R1. The upper ends of these columns 24L, 24R are hung on the upper edge of the heat exchanger 21 , and the lower ends of these columns 24L, 24R are fastened to the bottom plate 12 with screws.

The air blower 22A is composed of a fan motor 26A fixed to upper portions of the pillars 24L and 24R via a base 25, and a vane fan (axial fan) 27A attached to the shaft of the fan motor 26A. This blade fan 27A is arranged close to the front side of the heat exchange chamber R1. In addition, the front portion of the blade fan 27A protrudes into a circular rib-shaped fan cover portion 28A provided on the upper portion of the first front panel 14A of the heat exchange chamber R1, and the fan cover portion The opening of 28A functions as a ventilation path (air outlet), and this opening is covered by a fan guard (Fangard) 29A capable of preventing the human body and the like from coming into contact with the vane fan 27 . The air blower 22B is provided under the pillars 24L, 24R, and has substantially the same structure as the air blower 22A, so the same reference numerals as those constituting the air blower 22A are used, and description thereof is omitted.

When the fan motors 26A, 26B rotate and drive the vane fans 27A, 27B, outside air is sucked into the heat exchange chamber from the surroundings of the outdoor unit 10, more specifically, from the back side and the left side of the heat exchanger 21. In R1, outside air passes substantially the front of the heat exchanger 21, and then is discharged to the outside through the fan covers 28A and 28B on the front of the heat exchange chamber R1. That is, the outdoor unit 10 is configured as a front blowing type in which heat-exchanged air is blown from the front.

As shown in FIG. 1, in the machine room R2, components of the refrigeration circuit, such as a compressor 31, an accumulator 32, a four-way valve 33, and a valve body such as an expansion valve (not shown), which constitute a part of the refrigeration circuit, pass through piping. These refrigerating circuit components are connected and housed in the substantially lower space of the machine room R2.

In this configuration, both the compressor 31 and the accumulator 32 have compression containers of the same volume, and are arranged vertically in the machine room R2. Specifically, a compressor 31 is provided on the base plate 12 , and an accumulator 32 is mounted on 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 suppressed.

In addition, a support plate 36 is arranged at a substantially middle position on the front side of the machine room R2, and an auxiliary valve 37 for an air pipe and an auxiliary valve 38 for a liquid pipe are fixed to the support plate 36 . A gas pipe and a liquid pipe (not shown) of unit piping extending from the indoor unit are respectively connected to these auxiliary valves for gas pipe 37 and auxiliary valve 38 for liquid pipe, thereby constituting a refrigeration circuit in which refrigerant circulates. An electrical component box 40 is arranged in the upper space of the machine room R2, and various electrical components such as a control board for controlling the air conditioner are arranged in the electrical component box 40 . The structure of the electrical installation box 40 includes: a first support plate (support plate) 41 extending on the top of the partition plate 16, and a second support plate 42 installed on the first support plate 41, on these first support plates 41 Electrical components such as substrates are arranged on the second support plate 42 and the second support plate 42 .

Next, the mounting structure of the partition plate 16 and the accumulator 32 will be described.

3 is a perspective view showing the spacer 16 and the accumulator 32 , FIG. 4 is a perspective view showing the structure of the spacer 16 , and FIG. 5 is a top view showing the mounting state of the accumulator 32 on the spacer 16 .

As shown in FIG. 3 , the partition plate 16 is formed into a tray shape, and its structure includes: a base plate portion 16A disposed between the heat exchange chamber R1 and the machine room R2 for separating the heat exchange room R1 and the machine room R2; The front part 16B formed by bending the side edge on the front side of the substrate part 16A toward the machine room R2 side, the inclined part 16C formed by obliquely bending the side edge part on the back side of the substrate part 16A toward the machine room R2 side, and the inclined surface The side edge portion of the portion 16C and the rear portion 16D formed by bending the front portion 16B substantially in parallel, the upper portion 16E formed by bending the upper edge portion of the substrate portion 16A toward the machine room R2 side, and the substrate portion The lower edge portion of 16A and the upper surface portion 16E are substantially parallel to the lower surface portion 16F formed by bending toward the machine room R2 side.

Thus, the separator 16 is formed in the tray shape from a thin metal plate, and the rigidity (strength) of the separator 16 is improved. Furthermore, in this configuration, in order to further increase the rigidity of the partition plate 16 , a reinforcement plate 50 is provided on a part of the partition plate 16 . The reinforcing plate 50 is provided in close contact with one surface (the surface on the machine room side) of the partition plate 16 , and the accumulator 32 is attached to the partition plate 16 through the reinforcing plate 50 .

The accumulator 32 includes a container body 32A formed as a pressure container, and a pair of upper and lower mounting metal fittings 32B provided on the upper and lower portions of the container body 32A, respectively. As shown in FIG. 5 , this mounting bracket 32B is formed by fixing a bolt 32C at a substantially center of a substantially U-shaped metal fitting.

In addition, as shown in FIG. 3 , the reinforcing plate 50 is arranged at two positions above and below the partition plate 16 at a predetermined interval P corresponding to the mounting pitch of the mounting metal fitting 32B of the accumulator 32 . In this structure, since the reinforcing plate 50 is only attached to a part of the partition 16 , compared with the prior art in which the entire partition is formed by thickening and rolling, the manufacturing cost can be reduced. Furthermore, even when it is necessary to change the installation pitch of the installation metal fittings due to changing the capacity of the accumulator, the reinforcement plates 50 can be arranged on the partition plate 16 at intervals corresponding to the installation pitch, thereby enabling a wide range of applications. products.

The reinforcing plate 50 is formed from the front portion 16B of the partition plate 16 to the base plate portion 16A, the slope portion 16C, and the rear portion 16D, and is bent into substantially the same shape as the partition plate 16 . Specifically, as shown in FIG. 4, the reinforcing plate 50 includes: a base plate portion 50A corresponding to the base plate portion 16A, the front portion 16B, the slope portion 16C, and the rear portion 16D of the partition plate 16, a front portion 50B ( FIG. 5 ), The ribs 50E are formed by bending the upper and lower edges of the substrate portion 50A, front portion 50B ( FIG. 5 ), slope portion 50C, and rear portion 50D into a substantially L-shape, respectively, for the inclined portion 50C and the rear portion 50D.

Since the reinforcing plate 50 is formed into a tray shape by having the ribs 50E, the rigidity of the reinforcing plate 50 itself is increased. In addition, since the reinforcement plate 50 is formed into substantially the same shape as the partition plate 16 and is attached to the partition plate 16, the reinforcement plate 50 and the partition plate 16 are integrated, so that the partition plate 16 can be raised with a simple structure. rigidity.

In this configuration, the reinforcing plate 50 and the partition plate 16 are joined by spot welding, but they can also be joined by fastening screws or the like.

As shown in FIG. 3 , the partition plate 16 is erected on the bottom plate 12 by fastening the lower surface portion 16F of the partition plate 16 and the bottom plate 12 with screws. Furthermore, the back surface part 16D (one end) of the separator 16 is fastened to the heat exchanger 21 with a screw. Specifically, as shown in FIG. 3 , the heat exchanger 21 has a tube plate 35 attached to the end portion on the right side in the figure of the heat exchanger 21 . The edge is bent into a substantially L-shaped rib 35A. In this structure, as shown in FIG. 5 , the rear surface 16D of the partition plate 16 and the rear surface 50D of the reinforcing plate 50 are screwed together to the rib 35A of the tube plate 35 . Moreover, in this structure, the front part 16B of the partition board 16 and the front part 50B of the reinforcement board 50 are screwed together and fastened to the 1st front panel 14A. Thus, since the partition plate 16 is fixed to the tube sheet 35 and the first front panel 14A by the portion reinforced by the reinforcing plate 50, the partition plate 16 can be more firmly supported in the unit casing 11. The vibration of 16 is less likely to be transmitted to the heat exchanger 21 or each panel of the unit casing 11, so that the noise accompanying the vibration can be suppressed.

Since the accumulator 32 is mounted on the bulkhead 16 through the reinforcing plate 50, the rigidity of the bulkhead 16 can be improved by the reinforcing plate 50, the deformation of the bulkhead 16 due to the weight of the accumulator 32 can be prevented, and the The accumulator 32 vibrates to vibrate the diaphragm 16 .

As shown in FIG. 4 , a keyhole-shaped hole (hole portion) 52 penetrating through the base plate portion 16A of the partition plate 16 and the base plate portion 50A of the reinforcement plate 50 is formed. The keyhole hole 52 has a structure in which a large-diameter hole 52A and a small-diameter hole 52B are connected up and down, and the small-diameter hole 52B is formed to have a diameter smaller than that of the bolt 32C of the mounting metal fitting 32B of the accumulator 32. larger than the diameter of the nut 53 tightened on the bolt 32C. Also, the large-diameter hole 52A is formed to have a diameter larger than that of the nut 53 .

When the accumulator 32 is mounted on the partition plate 16, the bolt 32C is passed through the keyhole-shaped hole 52 together with the nut 53 while the nut 53 is tightened on the bolt 32C of the mounting metal fitting 32B of the accumulator 32. The large diameter hole 52A. Then, when the accumulator 32 is moved downward, the bolt 32C moves into the small-diameter hole 52B, and the nut 53 is hooked in the small-diameter hole 52B. Therefore, the accumulator 32 can be temporarily fixed to the separator 16 easily. Then, by tightening the nut 53 , the accumulator 32 can be fixed to the partition plate 16 . Therefore, since the keyhole-shaped hole 52 capable of hooking the mounting metal fitting 32B of the accumulator 32 is provided on the partition plate 16 and the reinforcing plate 50, the accumulator 32 can be temporarily fixed on the partition plate 16, thereby Even a single operator can easily attach the accumulator 32 to the partition plate 16 .

When installing the outdoor unit 10, the air pipe and the liquid pipe (not shown) of the unit piping are respectively connected to the auxiliary valve 37 for the air pipe and the auxiliary valve 38 for the liquid pipe. Add refrigerant. Therefore, since the possibility of attaching and detaching piping etc. to the auxiliary valve 37 for the gas line and the auxiliary valve 38 for the liquid line is relatively high, it is desirable to securely fix the auxiliary valve 37 for the gas line and the auxiliary valve 38 for the liquid line.

In this structure, since one end 36A of the support plate 36 is fixed to the partition plate 16 via the reinforcing plate 50 below, the piping can be easily attached and detached to the gas pipe auxiliary valve 37 and the liquid pipe auxiliary valve 38 .

According to this embodiment, since the inside of the unit casing 11 is divided into the heat exchange chamber R1 and the machine room R2 by the partition plate 16, the heat exchanger 21 and the blowers 22A and 22B are accommodated in the heat exchange room R1, and the machine room R2 The compressor 31 and the accumulator 32 are accommodated, the reinforcing plate 50 is attached to the partition 16, and the accumulator 32 is installed on the partition 16 through the reinforcing plate 50, so the structure is simple and the reinforced The plate 50 can increase the rigidity of the partition plate 16 , can prevent the partition plate 16 from being deformed by the weight of the accumulator 32 , and can suppress the vibration of the partition plate 16 accompanying the vibration of the accumulator 32 . Furthermore, since the back surface portion 16D of the partition plate 16 and the reinforcing plate 50 are fixed to the tube plate 35 of the heat exchanger 21, the partition plate 16 can be more firmly supported in the unit case 11, so that the The vibration of the partition plate 16 is less likely to be transmitted to the heat exchanger 21, and the noise accompanying the vibration can be suppressed.

According to this embodiment, the accumulator 32 has a container body 32A and a pair of mounting metal parts 32B fixed on the container body 32A. Since the reinforcing plate 50 is arranged on the partition plate 16 corresponding to the distance between these mounting metal parts 32B, , even if the installation pitch of the mounting metal parts of the reservoir changes, the reinforcing plate 50 can be arranged on the partition plate 16 at an interval corresponding to the pitch, so that it can widely correspond to various products used, and can To achieve the purpose of reducing manufacturing costs.

Therefore, even if rainwater infiltrates into the mechanical chamber R2 from the heat exchange chamber R1 through the gap between the partition plate 16 and the first support plate 41, the rainwater will flow downward in the mechanical chamber R2 when it encounters the tongue portion 41F. These rainwater will not soak into the electrical installation box 40 .

Moreover, the electrical installation box 40 has the 2nd support plate 42 fixed to the 1st support plate 41, and extending 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 is provided on the front side of the plate portion 42A. A filter substrate 46 is arranged, and a reactor 47 is arranged on the back side of the plate portion 42A.

On the front side of the plate portion 42A, a cover body 48 that covers the filter substrate 46 and is bent in a substantially U-shape when viewed from above is disposed. The cover body 48 is fixed to the plate portion 42A by screws or the like, and the cover body 48 can be easily detached from the plate portion 42A by removing the screws. A control board 49 capable of controlling the operation of various devices in the outdoor unit 10 is arranged on the front surface of the cover body 48 . Since the control board 49 is arranged on the front side of the machine room R2, maintenance can be easily performed by removing the second front panel 14B (see FIG. 2 ), for example.

In addition, a mounting plate 51 formed by bending a metal plate is fixed to the bottom plate portion 42B of the second supporting plate 42 , and a mounting plate 51 for supplying power to the outdoor unit 10 is arranged on the front side of the mounting plate 51 . Terminal block 52 for communication.

As described above, the electrical installation box 40 has the first support plate 41 and the second support plate 42. Since the converter substrate 43, Heat sink 44, filter substrate 46, reactor 47, control substrate 49, and unshown power relays and capacitors, etc., so the weight of the electrical installation box 40 becomes relatively heavy (for example, about 11kg), so this electrical installation box The installation operation of 40 is more difficult.

Therefore, in this configuration, in a state where the first support plate 41 of the electrical component box 40 is placed on the upper surface of the partition plate 16, the back surface portion 41C of the first support plate 41 can be temporarily fixed to the bottom of the heat exchanger 21. On the tube sheet 35. Specifically, as shown in FIG. 8 , a keyhole-shaped hole (hole portion) 61 capable of being hooked to a screw 62 attached to a rib of the tube plate 35 is formed on the rear surface portion 41C of the first support plate 41 . part 35A.

The keyhole-shaped hole 61 has a structure formed by associating a small-diameter hole 61A with a large-diameter hole 61B. The diameter of the small-diameter hole 61A is larger than the thread diameter of the screw 62 and smaller than the head diameter of the screw 62 . In addition, the diameter of the large-diameter hole 61B is larger than the head of the screw 62, and the head can pass therethrough.

In this structure, the keyhole-shaped hole 61 is formed obliquely so that the large-diameter hole 61B is positioned below the machine chamber R2 side relative to the small-diameter hole 61A. More specifically, the keyhole-shaped holes 61 are formed on substantially the same radius around the corner 41E1 on the heat exchange chamber R1 side of the lower surface portion 41E of the first support plate 41 as a center.

As described above, since the keyhole-shaped hole 61 is obliquely formed so that the large-diameter hole 61B is located below the machine room R2 side than the small-diameter hole 61A, as shown in FIG. However, the large-diameter hole 61B does not extend further toward the heat exchange chamber R1 side than the rib portion 35A of the tube sheet 35 . Accordingly, since the large-diameter hole 61B is blocked by the rib portion 35A, it is possible to prevent the heat exchange chamber R1 and the machine room R2 from being communicated through the large-diameter hole 61B, and to prevent rainwater from entering the large-diameter hole 61B. Inside the electrical installation box 40.

Next, the procedure for installing the electrical component box 40 will be described.

First, the first support plate 41 and the second support plate 42 are combined, and electrical components are arranged on the first support plate 41 and the second support plate 42 to form the electrical component box 40 .

Next, as shown in FIG. 8 , 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 tongue portion 41F is used as a guide and pressed into the bottom surface of the first support plate 41 . The back surface portion 41C reaches the rib portion 35A of the tube plate 35 of the heat exchanger 21 until it abuts against it. At this time, the electrical component box 40 can be pushed into a predetermined position with a small force by sliding the electrical component box 40 on the upper surface 16E of the partition plate 16 using the tongue portion 41F as a guide.

Next, as shown in FIG. 8 , the upper part of the electrical installation box 40 (for example, the upper surface 41D of the first support plate 41 ) is inclined toward the machine room R1 side, and the lock formed on the rear surface 41C of the first support plate 41 is locked. The large-diameter hole 61B of the eye-shaped hole 61 is inserted into the head of a screw 62 lightly screwed into the rib 35A of the tube sheet 35 in advance. As described above, since the keyhole-shaped holes 61 are formed on substantially the same radius centering on the corner 41E1 on the heat exchange chamber R1 side of the lower surface 41E of the first support plate 41, if the corner 41E1 is Center, rotate the first support plate 41 (electrical installation box 40) in the clockwise rotation direction (R direction in the figure), then the screw 62 moves in the small diameter hole 61A, and the head of the screw will be hooked on the small diameter hole 61A superior.

Therefore, the electrical installation box 40 can be simply and temporarily fixed on the unit casing 11 , specifically on the partition plate 16 and the tube plate 35 of the heat exchanger 21 . In addition, the screws 62 are tightened, and the electrical installation 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 .

The keyhole hole 61 of the screw 62 on the tube plate 35 of the heat exchanger 21, therefore, the electrical installation box 40 can be temporarily fixed on the partition plate 16 and the tube plate 35 of the heat exchanger 21, and even if the operator is alone The electrical installation box 40 can be easily installed in the unit casing 11 .

According to this embodiment, since the inside of the unit casing 11 is divided into the heat exchange chamber R1 and the machine room R2 by the partition plate 16, the heat exchanger 21 and the blowers 22A and 22B are accommodated in the heat exchange room R1, and the machine room R2 The compressor 31 and the electrical installation box 40 are accommodated. The electrical installation box 40 has a first support plate 41 extending on the partition plate 16 with approximately the same width as the partition plate 16 and supporting the inverter substrate 43 on the machine room R2 side. Therefore, on the side of the heat exchange chamber R1 of the first support plate 41 , only the cooling fins 44 for cooling the inverter substrate 43 protrude, thereby suppressing the protruding amount of the electrical component box 40 to the heat exchange chamber R1 side. Therefore, it is possible to suppress the wind resistance caused by the protrusion of the electrical component box 40 into the heat exchange chamber R1, and it is possible to improve the heat exchange efficiency of the heat exchanger 21 .

In particular, in the configuration in which the blowers 22A, 22B are arranged vertically as in the present embodiment, since the blowers 22A, 22B are arranged in the heat exchange chamber R1, by suppressing the amount of protrusion of the electrical box 40, the The air flow distribution of these air blowers 22A, 22B is optimal, so that it is possible to further improve the heat exchange efficiency of the heat exchanger 21 .

In the state where the first support plate 41 is placed on the upper surface 16E of the separator 16, since the back surface 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, it is possible to Simply install the electrical installation box 40 in the unit casing 11 .

According to this embodiment, since the first support plate 41 has the keyhole-shaped hole 61 on the back surface portion 41C of the first support plate 41, the screw 62 attached to the rib portion 35A of the tube plate 35 can be hooked, so the The electrical installation box 40 is temporarily fixed to the partition plate 16 and the tube plate 35 of the heat exchanger 21 , so that even a single operator can easily install the electrical installation box 40 in the unit casing 11 .

Furthermore, according to the present embodiment, since the keyhole-shaped hole 61 includes the small-diameter hole 61A and the large-diameter hole 61B, and these small-diameter holes 61A and the large-diameter hole 61B are formed in the lower surface portion 41E of the first support plate 41, the heat exchange chamber R1 Therefore, by rotating the first support plate 41 (electrical installation box 40) in a clockwise rotation direction (direction R in the figure) around the corner 41E1, The screw 62 can be easily hooked on the keyhole-shaped hole 61 .

In addition, according to the present embodiment, since the first support plate 41 has the tongue portion 41F extending from the lower surface portion 41E of the first support plate 41 toward the machine room R2 side of the upper surface portion 16E of the partition plate 16 , the electrical installation When installing the box 40, by sliding the electrical component box 40 on the upper surface 16E of the partition plate 16 using the tongue portion 41F as a guide, the electrical component box 40 can be pressed into a predetermined position with a small force.

Furthermore, since the tongue portion has the function of covering the gap between the first support plate 41 and the partition plate 16, even if rainwater infiltrates into the machine room R2 from the heat exchange chamber R1 through the gap between the partition plate 16 and the first support plate 41 Since the rainwater encounters the tongue portion 41F and flows below the machine room R2, it is possible to prevent the rainwater from entering the electrical installation box 40.

Next, the structure of the heat exchanger 21 will be described.

As shown in FIG. 9 , the heat exchanger 21 is formed by laminating a plurality (three in this embodiment) of fin-tube heat exchange parts 151 , 152 , and 153 in the thickness direction. The structure of the heat exchange part 151 arrange|positioned inside includes the refrigerant|coolant tube 151A through which a refrigerant|coolant flows, and the several fins 151B for heat dissipation arrange|positioned around this refrigerant|coolant tube 151A. In addition, the heat exchange parts 152 and 153 arranged in the middle and outer sides are formed in substantially the same size as the heat exchange part 151, and have substantially the same structure as the heat exchange part 151, so they are assigned the same reference numerals, The description thereof is omitted here.

As shown in FIG. 2 , the heat exchanging parts 151 to 153 are arranged with their right end positions aligned in the figure, and the first tube sheet 35 connecting the heat exchanging parts 151 to 153 is arranged at the end. The first tube plate 35 has a rib 35A that bends an edge portion of the first tube plate 35 inside the unit casing 11 into a substantially L-shape, and the partition plate 16 is fastened to the rib 35A.

As mentioned above, the heat exchange parts 151-153 are formed in substantially the same size, they arrange|position the position of the right end part in a drawing, and each is bent in substantially L shape when viewed from above. Therefore, the end portions on the left side (one side) in the drawing of the heat exchange portions 151 to 153 are not aligned, and the stepped portion 55 is formed on the end portion side. Specifically, the end portion 152C of the heat exchange portion 152 disposed in the middle is located behind the end portion 151C of the heat exchange portion 151 disposed on the inner side, and the heat exchange portion disposed on the outer side is more rearward than the end portion 152C. End 153C of 153 is located at the rear. Therefore, the positions of the respective end portions 151C to 153C are not aligned, and as a result, the stepped portion 155 is formed on the one end portion side of the heat exchanger 21 .

As shown in FIG. 10 , a guide plate 156 is disposed on the stepped portion 155 , and the guide plate introduces external air onto the stepped portion 155 through the operation of the blowers 22A, 22B. The guide plate 156 is a plate member having substantially the same height as the heat exchanger 21, and its structure includes a front surface portion 156A arranged substantially parallel to the fins 151B to 153B of the heat exchange portions 151 to 153 in the stepped portion 155, and the front surface portion 156A. A side portion 156B formed by bending one end of the front portion 156A toward the stepped portion 155, and a side portion 156B formed by bending the other end of the front portion 156A, that is, an end opposite to the side portion 156B, toward the front panel 14.

The second tube plate 157 includes: an end plate 157A arranged approximately parallel to the fins 151B of the heat exchange unit 151 ; The rib 157B is formed by bending toward the front panel 14 side. The rib portion 157B has substantially the same width as the fixing portion 156C of the guide plate 156 , and the guide plate 156 is attached to the heat exchange portion 151 by fitting the rib portion 157B and the fixing portion 156C together with screws. In this structure, the guide plate 156 can be simply formed by bending a single plate material.

On the one hand, the side surface (the other end) 156B of the guide plate 156 is attached to the bottom plate 12 . Specifically, the base plate 12 has a raised portion 112A around it, on which a recessed portion 112B is formed at a position opposed to the side portion 156B of the guide plate 156 . The recessed portion 112B is recessed to a position where it abuts against the side portion 156B. By fixing the recessed portion 112B and the side portion 156B with a screw 158 , the side portion (the other end) 156B of the guide plate 156 is attached to the bottom plate 12 .

As described above, since the fixed portion 156C of the guide plate 156 is attached to the second tube plate 157 of the heat exchange portion 151 arranged inside, the side surface portion 156B of the guide plate 156 is attached to the recessed portion 112B formed on the raised portion 112A of the bottom plate 12 . Inside, therefore, the heat exchanger 21 and the bottom plate 12 are connected together through the guide plate 156 . Therefore, a dedicated part for connecting the heat exchanger 21 to the base plate 12 is no longer required, thereby reducing the number of parts and attempting to simplify the assembly operation.

Here, the guide plate 156 is attached to the bottom plate 12 so that a gap 160 having a width W is formed between the side surface 156B of the guide plate 156 and the end 153C of the heat exchange unit 153 arranged outside. The width W of the gap 160 is large enough to allow external air to flow into the stepped portion 155 through the gap 160 .

Thus, the outside air sucked through the gap 160 by the operation of the blowers 22A, 22B is drawn into the guide plate 156 and passes through the stepped portion 155 of the heat exchanger 21 as shown by the arrow X in FIG. 11 . Therefore, it is attempted to improve the heat exchange efficiency of the heat exchanger 21 by circulating sufficient outside air through the stepped portion 155 which contributes to heat exchange.

In particular, when the heat exchanger 21 is formed by laminating three or more heat exchange parts 151 to 153 as in the present embodiment, as shown by the oblique lines in FIG. Larger, so the effect obtained is also further improved.

In addition, as shown in FIG. 10 , a plurality of (four in this embodiment, see FIG. 1 ) notches (openings) 161 are formed at predetermined pitches on the front portion 156A and the fixing portion 156C of the guide plate 156 . This notch 161 is used to connect the heat exchange part 151 arranged inside and the heat exchange part 152 arranged in the middle (adjacent to the heat exchange part). In this structure, the refrigerant tube 151A of the heat exchange part 151 arranged inside and the refrigerant tube 152A of the heat exchange part 152 arranged in the middle are bound by the band (connector) 162 through the cutout 161, so that the These heat exchanging parts 151, 152 are ground-connected.

束バンド)162捆紧制冷剂管151A，152A的操作。但是，为了使外部气体通过该切口161跑到热交换器21的内侧的空间，因此该切口161的大小优选小到不妨碍利用束带进行捆紧操作的程度。If this cutout 161 is enlarged, it is easy to carry out the utilization of the drawstring (

Bundle) 162 is used to tighten the refrigerant tubes 151A, 152A. However, in order to allow outside air to escape to the space inside the heat exchanger 21 through the cutout 161, the size of the cutout 161 is preferably small enough not to interfere with the tightening operation by the band.

In this configuration, though not shown, refrigerant tubes 152A of the heat exchange unit 152 disposed in the middle and refrigerant tubes 153A of the heat exchange unit 153 disposed outside the guide plate 156 can be bundled inside the guide plate 156 by bands. tight, thereby connecting the heat exchange parts 152, 153 together.

Although not shown, a recess is formed on the side portion 114A1 to abut against the side portion 156B, and the first front panel 114A is attached by screwing the recess and the side portion 156B. According to this structure, a tube sheet for mounting the first front panel 114A on the end portion 153C of the outer heat exchanging portion 153 is no longer necessary, thereby reducing the number of parts, and simplification of the assembly operation can be attempted.

As shown in FIG. 11 , in this structure, side portion 114A1 of first front panel 114A is attached so as to substantially overlap side portion 156B of guide plate 156 . According to this structure, the gap 160 can be prevented from being narrowed by the side portion 114A1 of the first front panel 114A, and the side portion 156B of the guide plate 156 can be prevented from being exposed to the outside due to the side portion 114A1, thereby improving the performance of the outdoor unit of the air conditioner. 10 aesthetics.

Therefore, sufficient external air flows through the step portion 155, and the step portion 155 contributes to heat exchange, thereby improving the heat exchange efficiency of the heat exchanger 21.

In addition, since the heat exchanger 21 and the bottom plate 12 are connected together through the guide plate 156, special components for connecting the heat exchanger 21 to the bottom plate 12 are no longer required, thereby reducing the number of parts and trying to simplify assembly operations.

Moreover, according to the present embodiment, since the first front panel 114A is installed on the guide plate 156, it is no longer necessary to install the first front panel 114A on the end 153C of the outer heat exchange part 153, thereby reducing number of parts and can attempt to simplify assembly operations.

Furthermore, according to the present embodiment, since the guide plate 156 is formed with the slit 161 through which the band 162 connecting the heat exchange unit 151 arranged on the inner side and the heat exchange unit 152 arranged in the middle passes, through this slit 161, the The band 162 fastens the refrigerant tube 151A of the inner heat exchange part 151 and the refrigerant tube 152A of the middle heat exchange part 152 so that these heat exchange parts 151 and 152 can be easily connected together.

Furthermore, according to the present embodiment, since the heat exchanger 21 is formed by laminating three heat exchange portions 151 to 153 of substantially the same shape, the area where the heat exchange is performed by the guide plate 156 is further enlarged compared to the area where two heat exchange portions are stacked. , so that the heat exchange efficiency can be further improved.
