Description

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

The outdoor unit of the air conditioner includes a heat exchanger having a plurality of fins arranged at predetermined intervals and a plurality of heat transfer tubes through which the refrigerant flows through the plurality of fins (for example, Patent Document 1). ).

The inside of the outdoor unit housing is partitioned by a partition plate into a heat exchange chamber in which the above-mentioned heat exchanger, fan, etc. are arranged, and a machine room in which a compressor, expansion valve, electrical component box, etc. are arranged. .. The heat exchanger is assembled to the bottom plate of the outdoor unit housing. The heat exchanger needs to be connected to a compressor or expansion valve arranged in the machine room by a refrigerant pipe, and a part of the heat exchanger is arranged in the machine room for this connection. That is, since the heat exchanger is arranged across the machine room and the heat exchange room, there is no partition plate at the place where the heat exchanger is arranged. Further, the bottom plate is provided with a drainage groove for discharging water such as condensed water generated by the heat exchanger and rainwater that has entered the inside of the outdoor unit to the outside of the outdoor unit. The drainage groove is formed in the bottom plate as a recess along the shape of the heat exchanger.

Japanese Unexamined Patent Publication No. 2010-210140

As described above, there is no partition plate at the place where the heat exchanger is arranged, and a drainage groove is formed below the heat exchanger from the machine room to the heat exchange room. Since the drainage groove is formed on the bottom plate as a recess, the lower surface of the heat exchanger and the drainage groove do not come into close contact with each other when the heat exchanger is assembled to the bottom plate. Therefore, a gap is formed between the lower part of the heat exchanger and the drainage ditch to communicate the machine room and the heat exchange room. If the size of this gap is large, it is possible to use a suction port for taking in outside air into the heat exchange chamber of the outdoor unit or an outlet for discharging the outside air that has exchanged heat with the refrigerant in the heat exchanger from the heat exchange chamber to the outside. Small animals that have invaded the heat exchange chamber may invade the machine room through the above gap. Then, if a small animal that has invaded the machine room invades the electrical equipment box, there is a risk of causing a problem such as a short circuit of the circuit board stored in the electrical equipment box.

The present invention solves the problems described above, and an object of the present invention is to provide an outdoor unit of an air conditioner capable of preventing small animals from entering the machine room from the heat exchange room.

In order to solve the above problems, the outdoor unit of the air conditioner according to the present invention has a housing whose inside is divided into a first chamber and a second chamber by a partition plate, and a housing inside the housing from the first chamber. It has a heat exchanger arranged over the second chamber. This outdoor unit forms a part of the housing and has a drainage groove formed in a concave shape from the first chamber to the second chamber below the heat exchanger and at a position corresponding to the shape of the heat exchanger 10. It has a bottom plate provided and a gap member provided with a protrusion and assembled to a heat exchanger. Then, when the heat exchanger to which the gap member is assembled is arranged on the bottom plate, the protruding portion is arranged in the drainage groove, and the protruding portion forms the boundary surface between the first chamber and the second chamber in the drainage groove.

According to the outdoor unit of the air conditioner of the present application, the first chamber and the second chamber are blocked by the protrusion, so that small animals invade the first chamber (machine room) from the second chamber (heat exchange chamber). Can be prevented.

Further, although not shown, the outdoor unit 1 includes a compressor, a four-way valve, an expansion valve, and an electrical component box for storing circuit boards such as a power supply board and a control board, which together with the heat exchanger 10 form a refrigerant circuit of the outdoor unit 1. It is provided inside the housing.

As shown in FIGS. 1A and 1B, the housing of the outdoor unit 1 includes a front panel 2, a top panel 3, a front support column 23, a rear side column 24, and a side panel 4. The bottom plate 8 and the partition plate 25 are formed in a rectangular parallelepiped shape.

The front panel 2 is made of sheet metal, and as shown in FIG. 1A, is arranged so as to cover a part of the right side of the front surface of the outdoor unit 2 (the front surface of the machine room 31 described later). The front side support column 23 is formed by bending a sheet metal into an L shape, and is arranged at the left end of the front surface of the outdoor unit 1 as shown in FIG. 1 (B). Two air outlets 21 that communicate the inside and the outside of the outdoor unit 1 are arranged vertically between the left end of the front panel 2 and the front support column 23, and the fan 41 also moves up and down so as to face the air outlet 21. Two are arranged in.

The back support column 24 is formed by bending a sheet metal into an L shape, and is arranged at the left end of the back surface of the outdoor unit 1. The back panel 5 is made of sheet metal and is arranged so as to cover a part of the right side of the back surface of the outdoor unit 1 (the back surface of the machine room 31 described later). Each of the space between the front column 23 and the rear column 24 and the space between the rear column 24 and the left end of the rear panel 5 are suction ports 21 that communicate the inside and the outside of the outdoor unit 1. As shown in FIGS. 1B and 2A, the L-shaped heat exchanger 10 is arranged so as to face the suction port 22. In FIG. 2, the drawing of the fan 41 is omitted.

The side panel 4 is made of sheet metal and is arranged so as to cover the right side surface of the outdoor unit 1 (the right side surface of the machine room 31 described later). The partition plate 25 is arranged so as to partition the inside of the housing of the outdoor unit 1 into a machine room 31 (corresponding to the first room of the present invention) and a heat exchange room 32 (corresponding to the second room of the present invention). It is formed by bending a sheet metal into a substantially C shape.

The bottom plate 8 is formed by bending the peripheral edge of the sheet metal upward. Each of the panels, the front side support column 23, the back side support column 24, the partition plate 25, the heat exchanger 10, the compressor forming the refrigerant circuit, and the like described above are fixed to the bottom plate 8. Further, as shown in FIGS. 2B and 3, the bottom plate 8 has a drainage groove for discharging water such as condensed water generated by the heat exchanger 10 and rainwater invading from the outside to the outside of the outdoor unit 1. 8a is provided. The drainage groove 8a is formed so as to have a concave bottom plate 8 and from the machine room 31 to the heat exchange chamber 32 along the lower surface 10a of the heat exchanger 10. The drainage groove 8a is provided with a drainage hole (not shown), and the drainage groove 8a is formed so as to be inclined toward the drainage hole. Therefore, the condensed water generated when the heat exchanger 10 functions as an evaporator and dropped into the drainage groove 8a flows into the drainage hole, and is drained from the drainage hole to the outside of the outdoor unit 1.

As described above, the heat exchanger 10, the fan 41, the compressor (not shown), the four-way valve, the expansion valve, and the electrical component box are arranged inside the housing of the outdoor unit 1 described above. Specifically, a compressor, a four-way valve, an expansion valve, and an electrical component box are arranged in the machine room 31. A part of the electrical component box is fixed to the upper end of the partition plate 25 shown in FIG. 2 (A) and is arranged above the machine room 31. Therefore, the space above the partition plate 25 inside the outdoor unit 1 is partitioned into the machine room 31 and the heat exchange room 32 by the electrical component box. On the other hand, the heat exchanger 10 and the fan 41 are arranged in the heat exchange chamber 32. The fan 41 is arranged so as to face the air outlet 21. The heat exchanger 10 is formed in a substantially L shape and is arranged so as to face each suction port 22 provided on the back surface and the left side surface.

As described above, most of the heat exchanger 10 fixed to the bottom plate 8 is arranged in the heat exchange chamber 32 and a part of the heat exchanger 10 is arranged in the machine room 31. Specifically, as shown in FIG. 1 (B), the end of the heat exchanger 10 on the side to which the side panel 4 is attached and connected to the compressor, the four-way valve, or the like by the refrigerant pipe (hereinafter referred to as heat). The exchanger end 11a) passes through the end of the partition plate 25 on the heat exchanger 10 side (hereinafter referred to as the partition plate end 25a) and crosses the straight line A parallel to the side panel 4 in the machine room. It is arranged at 31. Here, the straight line A is a virtual straight line for separating the machine room 31 and the heat exchange room 32 at a place where the partition plate 25 does not exist. That is, as shown in FIG. 3, the partition plate 25 does not exist in the drainage groove 8a below the lower surface 10a of the heat exchanger 10 below the portion on the straight line A where the heat exchanger end 11a is arranged. As a result, a communication port S is formed in which the machine room 31 and the heat exchange room 32 communicate with each other through the drainage groove 8a.

As shown in FIGS. 1B and 2, the heat exchanger 10 includes a plurality of fins 11 arranged at predetermined intervals and a plurality of heat transfer tubes 7 through which the refrigerant flows through the plurality of fins 11. It is formed in a substantially L shape as described above. As shown in FIGS. 2B and 3, in the heat exchanger 10, the heat exchanger 10 is arranged on the bottom plate 8 and the front side column so that the lower surface 10a of the heat exchanger 10 is arranged above the drainage groove 8a. It is assembled with a plurality of fixing brackets (not shown) shown in No. 23. The heat exchanger 10 exchanges heat between the plurality of fins 11 with the air passing in the air flow direction α shown in FIG. 2A and the refrigerant flowing through the plurality of heat transfer tubes 7.

The fin 11 is formed in a plate shape using aluminum or an aluminum alloy. A plurality of fins 11 are laminated at predetermined intervals, and air flows between them. As the fan 41 rotates, the air sucked from each suction port 22 and flowing into the heat exchange chamber 32 flows through the heat exchanger 10 in the direction of the arrow α shown in FIG. 2 (A). Further, as shown in FIG. 2, a side plate 6 is attached to the heat exchanger end portion 11a on the outside of the fins 11 arranged at the heat exchanger end portion 11a. The side plate 6 is formed by processing a sheet metal so that the height dimension is substantially the same as that of the fin 11 and the front-rear dimension (Y direction in FIG. 1A) is slightly larger than the fin 11.

The plurality of heat transfer tubes 7 are formed by forming copper pipes in a hairpin shape. The plurality of heat transfer tubes 7 are arranged side by side in the vertical direction in a direction orthogonal to the air flow direction α. As shown in FIGS. 1 (B) and 2 (A), in each heat transfer tube 7, at the end portion 11a of the heat exchanger, a part of the heat transfer tubes 7 is connected to a diversion device (not shown), and the other heat transfer tubes 7 are connected. In, one end of the heat transfer tube 7 and the end of the other heat transfer tube 7 are connected by a connecting tube 7a to form one pipe line. In the heat exchanger 10 of the present embodiment, a plurality of heat transfer tubes 7 are arranged in a row with respect to the air flow direction α, but depending on the capacity required for the air conditioner equipped with the heat exchanger 10. Therefore, the number of rows of the heat transfer tubes 7 may be increased or decreased as appropriate.

The assembly of the heat exchanger 10 described above is performed by the following procedure. First, a plurality of heat transfer tubes 7 are inserted through the plurality of fins 11 and the side plates 6. Specifically, each heat transfer tube 7 is inserted into a hole provided in a plurality of fins 11, and finally each heat transfer tube 7 is inserted into a hole provided in a side plate 6. Next, each heat transfer tube 7 is expanded to fix each heat transfer tube 7, each fin 11, and the side plate 6. Next, one end of one heat transfer tube 7 and one end of the connection tube 7a are welded and connected, and the other end of the connection tube 7a and one end of the other heat transfer tube 7 are welded. And connect. At this time, the side plate 6 is arranged inside (left side) from the welded portion between the end portion of the heat transfer pipe 7 and the connecting pipe 7a, that is, the fins arranged on the outermost side (right side) of the heat exchanger end portion 11a. The side plate 6 is interposed between the 11 and the welded portion. As a result, when the heat transfer tube 7 and the connection tube 7a are welded, the amount of heat transferred to the fins 11 arranged inside the side plate 6 is reduced, which is generated when the heat transfer tube 7 and the connection tube 7a are welded. It is possible to prevent the fin 11 from being deformed by heat.

By the way, as shown in FIG. 3, when the heat exchanger 10 is assembled to the bottom plate 8, a concave drainage groove 8a is located below the heat exchanger 10. If the distance between the heat exchanger 10 and the drainage ditch 8a is short, the lower part of the heat exchanger 10 will be covered with ice when the water existing in the drainage ditch 8a freezes in winter, and the area that works as the heat exchanger 10 will be covered. May decrease and the amount of heat exchange may decrease. Therefore, the heat exchanger 10 is assembled to the bottom plate 8 apart from the drainage groove 8a.

As described above, the inside of the outdoor unit 1 is divided into a machine room 31 and a heat exchange room 32 by a partition plate 25. On the other hand, when the heat exchanger 10 is separated from the drainage groove 8a and assembled to the bottom plate 8, the communication port S described above is formed. If the height and width of the communication port S are large and larger than the size that small animals such as insects can enter (for example, 9.0 mm), the suction port 22 or the blower from the outside of the outdoor unit 1 Small animals such as insects that have invaded the heat exchange chamber 32 through the outlet 21 have invaded the machine room 31 through the communication port S, and an electrical component box (not necessarily a closed box) arranged in the machine room 31 (not necessarily a closed box). It is not necessary, and a part of the circuit board may be opened to the machine room 31), and there is a risk of short-circuiting the circuit board such as the power supply board.

In order to solve the problems described above, the outdoor unit 1 of the air conditioner in the present embodiment has a gap member 9 attached to the lower surface 10a of the heat exchanger 10, and a protrusion 9d provided on the gap member 9 is provided. It is arranged at the communication port S. As a result, in the drainage groove 8a, the protruding portion 9d forms a boundary surface between the heat exchange chamber 32 and the machine room 31, and the area of the communication port S is reduced, so that small animals can enter the machine room 31 from the heat exchange room 32. Can be prevented. Hereinafter, the details of the gap member 9 will be described mainly with reference to FIG.

As shown in FIG. 4, the gap member 9 is formed in a substantially quadrangular shape using sheet metal, and has a base portion 9a in contact with the lower surface 10a of the heat exchanger 10 and a base portion 9a upward from one side of the base portion 9a. The first return portion 9b formed so as to extend continuously and the second return portion formed so as to extend continuously from the base portion 9a upward from one side opposite to the side on which the first return portion 9b of the base portion 9a is connected. It has a part 9c. The first return portion 9b is formed so as to be arranged on the upstream side of the air flow direction α when the gap member 9 is attached to the heat exchanger 10, and the second return portion 9c has the gap member 9 attached to the heat exchanger 10. It is formed so as to be arranged on the downstream side in the air flow direction α when attached to.

Further, of the two sides other than the side where the first return portion 9b and the second return portion 9c are connected to each other, one side arranged on the heat exchanger end portion 11a side is continuously extended downward from the base portion 9a. A protruding portion 9d formed in the above is provided. When the gap member 9 is attached to the lower surface 10a of the heat exchanger 10, the protruding portion 9d is arranged between the heat exchanger 10 and the drainage groove 8a to reduce the area of the communication port S and reduce the area of the communication port S to reduce the area of the heat exchange chamber. It is formed so that small animals cannot invade from 32 to the machine room 31. When the gap member 9 is assembled to the heat exchanger 10 by the method described later, the end portion of the end portion of the first return portion 9b facing the side plate 6 is designated as the first return portion end portion 9b1 and the second return portion 9b. The end portion of the end portion of the portion 9c facing the side plate 6 is referred to as the second return portion end portion 9c1.

In the gap member 9 described above, for example, a sheet metal is cut using a laser cutter or the like to cut out the outer shape of the gap member 9 including the first return portion 9b and the like, and the first return portion 9b and the second return portion 9c are cut out. , And each of the protruding portions 9d is bent up from the base portion 9a to form. At this time, the distance D between the first return portion 9b and the second return portion 9c shown in FIG. 4 is set to be slightly smaller than the thickness H of the heat exchanger 10 shown in FIG.

Next, a method of assembling the gap member 9 to the heat exchanger 10 will be described with reference to FIG. In FIG. 5, the drawing of the connecting pipe 7a is omitted, and the drawing of the side plate 6 is omitted in order to make it easier to understand the state in which the gap member 9 is attached to the heat exchanger 10.

First, as shown in FIG. 5A, the gap member 9 is brought closer to the lower surface 10a of the heat exchanger 10 from the lower side, that is, from the direction of the arrow β shown in FIG. 2 Assemble the gap member 9 to the heat exchanger 10 so that the heat exchanger 10 is arranged between the return portion 9c and the heat exchanger 10. As described above, since the distance D between the first return portion 9b and the second return portion 9c is set to be slightly smaller than the thickness H of the heat exchanger 10, when the gap member 9 is assembled to the heat exchanger 10. , The first return portion 9b and the second return portion 9c are elastically deformed outward, respectively. As a result, the first return portion 9b and the second return portion 9c of the gap member 9 sandwich the both end faces of the plurality of fins 11, and the assembly of the gap member 9 to the heat exchanger 10 is completed.

The method of assembling the gap member 9 is not limited to this. For example, the distance D between the first return portion 9b and the second return portion 9c is set to be slightly larger than the thickness H of the heat exchanger 10, and the first return portion 9b, the second return portion 9c, and the end faces of the fins 11 are formed. The gap member 9 may be assembled to the heat exchanger 10 by interposing an elastically deformable material such as a cushion material in the gap generated between the two.

When the heat exchanger 10 to which the gap member 9 described above is assembled is assembled to the bottom plate 8, the protruding portion 9d is arranged at the communication port S of the drainage groove 8a as shown in FIG. More specifically, the protrusion 9d is arranged below the straight line A shown in FIG. 1 (B) in the drainage groove 8a. As a result, the area of the communication port S between the machine chamber 31 and the heat exchange chamber 32 in the drainage groove 8a, excluding the gap between the lower end of the protrusion 9d and the drainage groove 8a (hereinafter referred to as the gap L). Is reduced by the protrusion 9d. In FIG. 6, the drawing of the connecting pipe 7a is omitted as in FIG.

The protruding portion 9d is formed so that the height dimension of the gap L is the first predetermined dimension (for example, 2.5 mm). Here, the first predetermined dimension is such that a small animal having a size that may invade the electrical component box and cause a problem such as short-circuiting a circuit component moves from the heat exchange chamber 32 to the machine room 31 through the gap L. The water generated in the machine room 31 or invading the machine room 31 from the outside and dripping into the drainage groove 8a located in the machine room 31 is allowed to flow into the heat exchange room 32 through the gap L. Is the distance that can be achieved. Further, by providing this gap L, even if the protrusion 9d and the drainage groove 8a move in a direction approaching each other due to vibration generated during transportation of the outdoor unit 1 or dropping of the outdoor unit 1, contact between the two is prevented. , It is possible to prevent the protruding portion 9d from being deformed due to contact with the drainage groove 8a.

As described above, in the outdoor unit 1 of the air conditioner of the present embodiment, the gap member 9 is attached to the lower surface 10a of the heat exchanger 10 so that the gap member 9 is between the heat exchanger 10 10a and the drainage groove 8a. The protruding portion 9d of the gap member 9 is arranged at the resulting communication port S. As a result, it is possible to prevent small animals such as insects that have invaded the heat exchange chamber 32 from invading the machine room 31 through the communication port S. It is possible to prevent a small animal that has invaded the machine room 31 from invading the electrical component box and short-circuiting the circuit board. Further, by providing a gap L separated by a first predetermined dimension between the lower end of the protruding portion 9d of the gap member 9 and the drainage groove 8a, water that has entered the machine room 31 or water generated in the machine room 31 can be removed. The water can be drained to the heat exchange chamber 32 without delay through the gap L. Further, it is possible to prevent the protruding portion 9d of the gap member 9 from coming into contact with the drainage groove 8a of the bottom plate 8 to be deformed due to vibration or dropping during transportation of the outdoor unit 1.

The gap member 9 may be provided with an abutting portion 9b2 for positioning the gap member 9, as shown in FIGS. 4 and 5 (A). As described above, the protruding portion 9d of the gap member 9 is arranged below the communication port S formed in the drainage groove 8a where the partition plate 25 does not exist, that is, the straight line A shown in FIG. 1 (B). For example, the protrusion 9d can prevent small animals such as insects from invading the heat exchange chamber 32 into the machine chamber 31. On the other hand, when the position of the protrusion 9d is arranged at a position away from the straight line A, that is, when the protrusion 9d is arranged at a different place of the drainage groove 8a instead of the straight line A, the heat exchange chamber is arranged at the protrusion 9d. It is not possible to prevent the invasion of small animals such as insects from 32 into the machine room 31.

Therefore, as shown in FIG. 7, abutting portion 9b2 is provided so that a part of the upper portion of the first return portion end portion 9b1 is convex outward from the first return portion end portion 9b1, and the heat exchanger 10 is provided. When the gap member 9 is attached to the gap member 9, the abutting portion 9b2 is abutted against the side plate 6 so that the protruding portion 9d of the gap member 9 is arranged below the communication port S, that is, the straight line A shown in FIG. 1 (B). In addition, the gap member 9 is positioned. At this time, the shape of the abutting portion 9b2 is such that when the heat exchanger 10 is assembled to the bottom plate 8, the protruding portion 9d of the gap member 9 is arranged below the straight line A shown in FIG. 1 (B). Any shape may be used as long as the gap member 9 can be positioned. By providing the abutting portion 9b2 on the gap member 9 in this way, the protruding portion 9d can be easily positioned, and the area of the communication port S can be reliably reduced at the protruding portion 9d, thereby causing the heat exchange chamber 32 to the machine room. It is possible to prevent the invasion of small animals into 31.

Next, a second embodiment of the present invention will be described. In the present embodiment, as will be described later, a part of the configuration of the gap member 91 is different from the gap member 9 of the first embodiment. Since the configurations other than the above are the same as those of the first embodiment, detailed description thereof will be omitted.

As shown in FIG. 8, the gap member 91 of the present embodiment is provided with a plurality of (six in FIG. 8) penetrating portions 91a in the protruding portion 9d. The penetrating portion 91a is a round hole, and its diameter is set to be smaller than or equal to the first predetermined dimension described in the first embodiment. By providing the penetrating portion 91a in the protruding portion 9d, the water that has entered the machine room 31 or that has been generated in the machine room 31 and has flowed down into the drainage groove 8a is transferred to the heat exchange chamber 32 as compared with the first embodiment. It can flow smoothly. The penetrating portion 91a may not be a round hole but a slit whose width dimension is equal to or less than the first predetermined dimension.
