The present invention relates to an outdoor unit of a refrigeration apparatus.
Background
Conventionally, as an outdoor unit of a refrigeration apparatus, an outdoor unit including a casing, a fan, an electric substrate, and a partition plate is known. The partition plate partitions an internal space of the casing into a blower chamber in which the fan is disposed and a machine chamber in which the electrical substrate is disposed.
For example, in an outdoor unit described in patent document 1 (japanese patent application laid-open No. 2012-145287), a partition plate has a communication hole communicating with a blowing chamber and a machine chamber, and a reactor mounting member supporting a reactor is provided to face the communication hole. The space formed by the partition plate and the communication hole is open toward the back side of the outdoor unit, and the electric device substrate is positioned on the back side with respect to the opening.
Disclosure of Invention
Problems to be solved by the invention
In the outdoor unit of the air conditioner described in patent document 1, when the rotation of the fan is stopped, water such as rainwater may be blown into the blower chamber from a discharge port of the outdoor unit and enter the machine chamber from the blower chamber through a communication hole of the partition plate. In this case, if the electrical substrate is positioned on the back side with respect to the opening communicating with the communication hole, the electrical substrate may be wetted with water.
The present disclosure provides an outdoor unit of a refrigeration apparatus capable of suppressing wetting of an electric substrate with water.
Means for solving the problems
(1) An outdoor unit of a refrigeration device is provided with a casing, a fan, an electric substrate, a partition plate, a first plate, and a wall. The fan is accommodated in the housing. The electric substrate is accommodated in the housing. The partition plate divides the internal space of the casing into an air supply chamber and a machine chamber. A fan is disposed in the blowing chamber. An electrical substrate is disposed in the machine chamber. The partition plate has holes communicating with the air blowing chamber and the machine chamber. The first plate is disposed in the machine room so as to cover the hole and spaced apart from the partition plate. The wall is located between the first plate and the divider plate. The wall divides the opening together with the first plate and the partition plate. The first plate has a first end and a second end opposite the first end. The first end defines at least a portion of the opening. The electrical substrate is separated from the opening in a first direction from the first end toward the second end.
According to the outdoor unit of the refrigerating apparatus, even if water enters the machine room through the hole of the partition plate, the electric substrate can be prevented from being wetted by the water.
(2) The casing may have an outlet. The air outlet faces the fan. The hole may be located between the outlet and the opening.
According to the outdoor unit of the refrigeration apparatus, when the fan rotates, the air from the machine chamber flows into the blowing chamber through the opening and the hole in this order, and is blown out from the blowing port. Therefore, a smooth air flow in the case can be ensured, and the electric substrate can be stably cooled.
(3) The distance in the first direction between the hole and the second end may also be shorter than the distance in the first direction between the first end and the hole.
According to the outdoor unit of the refrigeration apparatus, the distance in the first direction from the hole to the opening can be secured longer than in the case where the distance in the first direction between the first end and the hole is shorter than the distance in the first direction between the hole and the second end. Thus, water that has entered the machine chamber through the hole is discharged from the opening, and therefore, water that has passed through the opening can be prevented from reaching the electrical substrate.
(4) The distance in the first direction between the aperture and the electrical substrate may also be shorter than the distance in the first direction between the opening and the electrical substrate.
According to the outdoor unit of the refrigeration apparatus, the distance in the first direction from the opening to the electrical component substrate can be secured longer than the distance in the first direction between the opening and the electrical component substrate is shorter than the distance in the first direction between the hole and the electrical component substrate. Therefore, the water passing through the opening can be prevented from reaching the electric substrate.
(5) The outdoor unit of the refrigeration apparatus may further include a second plate. The second plate is connected to the first plate and supports the electrical substrate.
According to the outdoor unit of a refrigeration apparatus, since the second plate is coupled to the first plate, the strength of the first plate can be improved.
(6) The outdoor unit of the refrigeration apparatus according to (5) above may further include an electric component. The electrical component is supported by the second plate.
In the outdoor unit of the refrigeration apparatus, the second plate supports the electrical component board and the electrical component. Therefore, 1 component can support both the electrical substrate and the electrical component. As a result, the number of components can be reduced as compared with a case where the electrical substrate and the electrical component are supported by different components.
(7) The outdoor unit of the refrigeration apparatus may further include a second electrical substrate. The second electrical substrate is supported by the first plate.
According to the outdoor unit of the refrigeration device, 2 electric substrates can be prevented from being wetted by water.
(8) The outdoor unit of the refrigeration apparatus may include a third plate. The third plate is provided in the blowing chamber so as to have a portion facing the hole with a space.
According to the outdoor unit of the refrigeration apparatus, water can be prevented from entering the air blowing chamber.
(9) In the outdoor unit of a refrigeration apparatus recited in the above (8), the third plate may have a third end and a fourth end opposite to the third end. The third end is connected with the partition plate. The fourth end is separated from the divider plate.
In the outdoor unit of such a refrigerating apparatus, water entering the air supply chamber contacts a third end connected to the partition plate and a portion facing the aperture with a space therebetween. Therefore, the water contacts the third plate and falls into the air blowing chamber. As a result, water can be prevented from entering the hole from the blowing chamber.
Further, the air from the machine chamber toward the air blowing chamber passes through the hole, and then passes between the fourth end and the partition plate to reach the air blowing chamber. Therefore, air can be allowed to flow from the machine chamber to the blower chamber, and the electric substrates can be stably cooled.
(10) The casing may have an outlet. The air outlet faces the fan. The third end may be closer to the outlet than the fourth end.
According to the outdoor unit of the refrigeration apparatus, since the water entering the blowing chamber from the discharge port contacts the third end closer to the discharge port than the fourth end, the water can be stably prevented from entering the intake port.

As shown in fig. 6, the cover member 10 includes a flat plate 11 as an example of the first plate and a frame wall 13 as an example of the wall.
(1) Flat plate
The flat plate 11 is disposed in the machine chamber 21 so as to cover the hole 30 with a space from the partition plate 3. The flat plate 11 faces the partition plate 3 across a gap in the width direction so as to cover the entirety of the plurality of holes 30.

The flat plate 11 extends in the up-down direction and the front-rear direction. The flat plate 11 is disposed parallel to the partition plate 3. Therefore, the thickness direction of the flat plate 11 is the same as the thickness direction of the partition plate 3. The thickness direction and the width direction of the flat plate 11 are the same.
As shown in fig. 5, the flat plate 11 has a first end 11A and a second end 11B opposite to the first end 11A in the front-rear direction (the direction orthogonal to both the up-down direction and the thickness direction of the flat plate 11). The first end 11A is located on the opposite side of the second front plate 26 with respect to the second end 11B. In the present embodiment, the first end 11A is the rear end of the flat plate 11, and the second end 11B is the front end of the flat plate 11. Further, a plurality of holes 30 are arranged between the first end 11A and the second end 11B in the front-rear direction.
Hereinafter, a direction from the first end 11A toward the second end 11B in the front-rear direction is referred to as a first direction. In the present embodiment, the first direction is a direction from the rear toward the front.
A distance L1 in the first direction between the hole 30 and the end face of the second end 11B is shorter than a distance L2 in the first direction between the end face of the first end 11A and the hole 30. Therefore, the distance in the first direction from the hole 30 to the opening 17 can be secured long, and the water that has entered the machine chamber 21 from the hole 30 is discharged from the opening 17, so that the water that has passed through the opening 17 can be suppressed from reaching the electrical substrate 8.
(2) Frame wall
As shown in fig. 6, the frame wall 13 is located between the flat plate 11 and the partition plate 3. The frame wall 13 surrounds the peripheral end of the flat plate 11 so as to be open rearward. The frame wall 13 is connected to the flat plate 11. The frame wall 13 may be integral with the flat plate 11 or may be separate from the flat plate 11. The frame wall 13 extends from the flat plate 11 toward the partition plate 3, and is in contact with the partition plate 3.
As shown in fig. 6 and 7, the frame wall 13 has a U-shape when viewed in a cross section parallel to the partition plate 3. The frame wall 13 has a first wall 14, a second wall 15, and a third wall 16.
The first wall 14 is a portion of the frame wall 13 between the second end 11B and the partition plate 3. The first wall 14 is joined to the second end 11B and is in contact with the partition plate 3. The first wall 14 extends in the up-down direction and the width direction. The vertical dimension of the first wall 14 is the same as the vertical dimension of the flat plate 11.
The second wall 15 is a portion of the frame wall 13 between the upper end of the flat plate 11 and the partition plate 3. The second wall 15 is joined to the upper end of the flat plate 11 and is in contact with the partition plate 3. The second wall 15 extends in the first direction and the width direction. The first direction dimension of the second wall 15 is the same as the first direction dimension of the flat plate 11. The second wall 15 has a first end 15A and a second end 15B located at a position separated from the first end 15A in the first direction. The second end 15B is continuous with the upper end of the first wall 14.
The third wall 16 is a portion of the frame wall 13 between the lower end of the flat plate 11 and the partition plate 3. The third wall 16 is connected to the lower end of the flat plate 11 and contacts the partition plate 3. The third wall 16 is disposed at a distance from the second wall 15 in the vertical direction. The third wall 16 extends in the first direction and the width direction. The third wall 16 has the same dimension in the first direction as the flat plate 11. The third wall 16 has a first end 16A and a second end 16B located apart from the first end 16A in the first direction. The first end 16A is disposed at a distance from the first end 15A in the vertical direction. The second end 16B is continuous with the lower end of the first wall 14.
The frame wall 13 defines an opening 17 together with the flat plate 11 and the partition plate 3. More specifically, first end 11A of flat plate 11, first end 15A of second wall 15, first end 16A of third wall 16, and partition plate 3 define opening 17. In other words, the first end 11A of the plate 11 delimits at least a part of the opening 17.
The opening 17 has a rectangular shape extending in the vertical direction when viewed from the first direction. An opening 17 is formed between the flat plate 11 and the partition plate 3. The space S in the frame wall 13 communicates with the space outside the space S via the opening 17. A plurality of holes 30 are located between the first wall 14 and the opening 17. The distance in the first direction between the hole 30 and the first wall 14 is shorter than the distance in the first direction between the opening 17 and the hole 30.
The plurality of holes 30 are located between the blow-out port 22 and the opening 17 in the first direction. Therefore, when the fan 7 is rotationally driven, the air from the machine chamber 21 flows to the blowing chamber 20 through the opening 17 and the hole 30 in this order, and is blown out from the blow-out port 22. As a result, a smooth air flow in the housing 2 can be ensured, and the electric substrate 8 can be stably cooled.
4. Details of the support plates
As shown in fig. 4, the support plate 12 is disposed at an upward interval with respect to the third suction port 26A. As shown in fig. 5, the support plate 12 is disposed at a rearward interval with respect to the second front plate 26. The support plate 12 is coupled to the plate 11. Therefore, the strength of the flat plate 11 can be improved.
The support plate 12 may be integral with the flat plate 11 or may be separate from the flat plate 11. The support plate 12 is located on the opposite side of the partition plate 3 with respect to the flat plate 11. In the present embodiment, the support plate 12 is continuous with the second end 11B of the flat plate 11. The support plate 12 extends in the width direction and the vertical direction so as to be orthogonal to the first direction.
5. Details of the electric substrate and the electric component
The plurality of electrical substrates 8 includes a first electrical substrate 80 and a second electrical substrate 81.
The first electrical substrate 80 is separated from the opening 17 in the first direction. Therefore, even if water enters the machine chamber 21 from the hole 30 of the partition plate 3, the water is discharged from the opening 17 so as to be away from the first electrical substrate 80. As a result, the first electrical substrate 80 can be inhibited from being wetted with water.
In addition, the first electrical substrate 80 is separated from the plurality of holes 30 in the first direction. The distance L3 in the first direction between the hole 30 and the first electrical substrate 80 is shorter than the distance L4 in the first direction between the opening 17 and the first electrical substrate 80. Therefore, the distance in the first direction from the opening 17 to the first electrical substrate 80 can be ensured to be long, and the water that has passed through the opening 17 can be suppressed from reaching the first electrical substrate 80.
The first electrical substrate 80 is positioned opposite the opening 17 relative to the support plate 12. The first electrical substrate 80 extends in the width direction and the vertical direction so as to be orthogonal to the first direction.
The support plate 12 supports the first electrical substrate 80. The support plate 12 is disposed between the third suction port 26A (see fig. 3) and the flat plate 11 in the width direction, and extends along a plane orthogonal to the first direction. Therefore, the support plate 12 can support the first electrical board 80 between the third inlet 26A (see fig. 3) and the opening 17 in the width direction. As a result, the air flow from the third air inlet 26A (see fig. 3) toward the opening 17 can pass through the vicinity of the first electrical board 80, and the first electrical board 80 can be stably cooled.
The first electrical substrate 80 is supported on the front surface of the support plate 12. Therefore, when the second front plate 26 is detached from the housing 2, the first electrical board 80 is exposed from the front. As a result, the installation worker or the maintenance worker can easily perform the wiring inspection and the voltage inspection of the first electrical substrate 80, the replacement of the first electrical substrate 80, and the like.
The second electrical substrate 81 is separated from the opening 17 in the first direction. Therefore, the first and second electrical substrates 80 and 81 can be prevented from being wetted with water. The second electrical substrate 81 is positioned between the first electrical substrate 80 and the opening 17. In more detail, the second electrical substrate 81 is located between the support plate 12 and the opening 17. The second electrical substrate 81 is located on the opposite side of the partition plate 3 with respect to the flat plate 11. The second electrical substrate 81 extends in the first direction and the up-down direction.
The second electrical substrate 81 is supported by the plate 11. The second electrical substrate 81 is supported on the surface of the plate 11 opposite to the surface facing the opening 17. Therefore, the first electrical board 80 and the second electrical board 81 can be disposed separately so as to effectively utilize the space in the casing 2, and the outdoor unit 1 can be made compact.
The electrical component 9 is separated from the opening 17 in the first direction. The electrical component 9 is located on a first, opposite side of the electrical substrate 80 with respect to the support plate 12.
The electrical component 9 is supported on the rear surface of the support plate 12. Therefore, the first electrical substrate 80 and the electrical component 9 are supported by the support plate 12. As a result, the 1 support plate 12 can support both the first electrical substrate 80 and the electrical component 9. Thus, as compared with the case where the first electrical board 80 and the electrical component 9 are supported by different components, the number of components can be reduced, and the length of the wiring connecting the first electrical board 80 and the electrical component 9 can be shortened.
Further, by detaching the support plate 12 supporting both the first electrical board 80 and the electrical component 9 from the outdoor unit 1, maintenance work of the first electrical board 80 and the electrical component 9 can be performed. Therefore, the maintenance work of the first electrical substrate 80 and the electrical components 9 can be facilitated.
6. Details of the dividing plate
A cover plate 31 as an example of the third plate is provided on the partition plate 3.
The cover plate 31 is provided in the blowing chamber 20. The cover plate 31 is located on the opposite side of the flat plate 11 with respect to the partition plate 3. In the present embodiment, the cover plate 31 is provided in plural numbers corresponding to the plural holes 30.
The hood plate 31 has a main body portion 31A and a coupling portion 31B. The body portion 31A faces the hole 30 with a space. Therefore, the water immersed into the plenum 20 comes into contact with the main body portion 31A before passing through the holes 30. As a result, water falls into the air sending chamber 20. This can prevent water from entering the hole 30 from the blowing chamber 20.
The main body portion 31A extends in the front-rear direction. The front end of the main body portion 31A is connected to the coupling portion 31B. The rear end 31C of the main body portion 31A is an example of a fourth end, and is separated from the partition plate 3.
The coupling portion 31B couples the front end of the main body portion 31A with the peripheral edge of the hole 30 of the partition plate 3. The coupling portion 31B extends in the width direction. One end of the coupling portion 31B is connected to the front end of the main body portion 31A. The other end 31D of the coupling portion 31B is an example of a third end, and is connected to the partition plate 3. In other words, cover plate 31 has a third end (the other end 31D) connected to partition plate 3 and a fourth end (rear end 31C) opposite to the third end. Although not shown, the cover plate 31 is connected to the partition plate 3 at the upper and lower ends thereof.
The other end 31D of the connecting portion 31B is closer to the air outlet 22 than the rear end 31C of the main body portion 31A. In other words, the cover plate 31 is open toward the outdoor heat exchanger 6, and the end portion close to the blow-out port 22 is closed. Therefore, the water entering the air sending chamber 20 from the air outlet 22 contacts the other end 31D of the connecting portion 31B where the cover plate 31 is closed, prior to the rear end 31C of the main body portion 31A where the cover plate 31 is opened. As a result, the water entering the air sending chamber 20 from the air outlet 22 can be stably suppressed from entering the holes 30.
When fan 7 rotates in the normal rotation direction, air that has passed from machine compartment 21 to blower compartment 20 passes through hole 30, passes between rear end 31C of main body 31A and partition plate 3, and reaches blower compartment 20. As a result, air can be allowed to flow from the machine compartment 21 to the blower compartment 20, and the electrical substrates 8 can be cooled stably.
In the present embodiment, the cover plate 31 is formed integrally with the partition plate 3 and is formed in a louver shape by cutting. The cover plate 31 may be separate from the partition plate 3. In this case, the cover plate 31 is connected to the partition plate 3 by, for example, spot welding.
7. Air flow in outdoor unit
Next, the air flow in the outdoor unit 1 will be described with reference to fig. 3 to 7.
As shown in fig. 3, the fan 7 is rotated in a normal rotation direction by a driving force input from the motor 70. When the fan 7 rotates in the normal rotation direction, the outside air is drawn into the air sending chamber 20 via the first and second suction ports 23 and 28A, and passes through the outdoor heat exchanger 6. The air having passed through the outdoor heat exchanger 6 is discharged from the air outlet 22.
At this time, in the machine chamber 21, as shown in fig. 4, the outside air flows into the machine chamber 21 through the third suction port 26A. The air flowing into the machine chamber 21 rises in the machine chamber 21. The air flow F is branched below the support plate 12 into a first air flow F1 passing near the first electrical substrate 80 and a second air flow F2 passing near the second electrical substrate 81.
Further, the first air flow F1 rises near the first electrical substrate 80, and cools the first electrical substrate 80. Thereafter, the first air flow F1 passes over the upper end of the support plate 12 and between the upper end of the support plate 12 and the top plate 29. Then, the first air flow F1 passes through the vicinity of the electrical components 9 and the second electrical substrates 81, cools the electrical components 9 and the second electrical substrates 81, and then flows into the opening 17.
The second air flow F2 rises near the second electrical substrate 81 and the electrical component 9, and cools the second electrical substrate 81 and the electrical component 9. After that, the second air flow F2 flows into the opening 17.
Next, as shown in fig. 5, the air flow F flowing into the opening 17 flows toward the plurality of holes 30 in the space S between the flat plate 11 and the partition plate 3. The flow direction of the air at this time is the same as the first direction. Thereafter, the air flow F passes through the plurality of holes 30, changes the direction of the flow by the cover plate 31, and reaches the blowing chamber 20. Then, the air flowing into the blowing chamber 20 is discharged from the outlet 22 by the rotation of the fan 7.
8. Immersion of water in outdoor units
As shown in fig. 8, when the fan 7 is stopped, rainwater and wind may be blown into the air-blowing chamber 20 from the air outlet 22. In this case, the rainwater collides with the fan 7 and strikes the partition plate 3.
In this case, the water hitting the fan 7 first comes into contact with the hood plate 31. Thereby, a part of the water contacts the cover plate 31 and falls into the blower chamber 20. Therefore, the intrusion of water into the holes 30 is suppressed.
When water flows between rear end 31C of main body portion 31A and partition plate 3 and enters space S between partition plate 3 and flat plate 11 through hole 30, a part of the water contacts flat plate 11 and falls into cover member 10. The water entering the space S may flow toward the opening 17 with the flow direction of the water changed by the flat plate 11. However, the water is discharged from the opening 17 so as to be away from the plurality of electric substrates 8. Therefore, even if water is discharged from the opening 17, the electrical substrate 8 can be inhibited from being wetted with water.
