JP 59-150231 A

  The problem in the conventional example is that the room temperature rises during the dehumidifying operation, so that the comfort is lacking.

  That is, in the conventional product, when dehumidifying the room, the heat pump first converts the refrigerant into a high-temperature and high-pressure gas state with a compressor, the refrigerant flows to the radiator, applies air to the radiator, and dissipates heat. By cooling the chamber, the refrigerant is deprived of heat and liquefied. Next, the refrigerant liquefied by the radiator is made into a gas-liquid two-layer state by lowering the pressure by the expansion means. Let the refrigerant in the state flow to the heat absorber. Then, since a heat absorber is cooled, if indoor air is applied to this heat absorber, it can dew and dehumidify. Here, in order to raise the dehumidification efficiency in a heat absorber, it is necessary to cool efficiently by blowing indoor air to a radiator. However, by cooling the radiator, the temperature of the air rises and is released into the room. For example, during the rainy season when dehumidification is performed, if the air whose temperature has been raised is released into the room, the room temperature rises, resulting in lack of comfort.

  Therefore, the present invention aims to improve comfort.

  In order to achieve this object, the present invention includes an air inlet, a main body case having first and second exhaust ports, a heat pump provided in the main body case, and a heat exchanger, and the heat pump Is formed by a compressor and a radiator, an expansion means, and a heat absorber sequentially provided downstream of the compressor, and the heat exchanger is disposed in a space between the heat radiator and the heat absorber in the main body case. A first blowing means for blowing the air sucked into the main body case from the intake port to the first exhaust port through one part of the radiator, and the inside of the main body case from the intake port. A second blowing means for blowing the air sucked into the second exhaust port through the heat exchanger, the heat absorber, the heat exchanger, and the other part of the radiator sequentially, The second exhaust port is equipped with communication means that communicates with the outdoors. , Thereby it is to achieve the intended purpose.

  As described above, the present invention includes a main body case having an intake port, first and second exhaust ports, a heat pump provided in the main body case, and a heat exchanger, and the heat pump includes a compressor. And a radiator, an expansion means, and a heat absorber sequentially provided downstream of the compressor, and the heat exchanger is provided in a space between the radiator and the heat absorber in the main body case, First air blowing means for blowing air sucked into the main body case from the air inlet into the first exhaust port through one part of the radiator, and air sucked into the main body case from the air inlet A second blower means for blowing air to the second exhaust port through the heat exchanger, the heat absorber, the heat exchanger, and the other part of the radiator sequentially, and the first exhaust port. In addition, it is equipped with a communication means that communicates with the outdoors. It can be achieved.

  That is, in the dehumidifying operation, first, the refrigerant is changed to a high-temperature and high-pressure gas state by the compressor, and the refrigerant flows to the radiator. And by cooling this heat radiator with the ventilation by the 1st, 2nd ventilation means, heat is taken away and it liquefies. Next, the refrigerant liquefied by the radiator is brought to a low pressure by the expansion means to make a gas-liquid two-layer state, and finally, the refrigerant in the gas-liquid two-layer state is passed through the heat absorber. The air is dehumidified by applying the indoor air to the heat absorber by the second blowing means to cause condensation. Here, the indoor air flows from the intake port through the heat exchanger to the heat absorber by the second air blowing means, and is again exhausted from the second exhaust port to the room through the heat exchanger and the heat radiator in turn. . That is, first, the indoor air is cooled by exchanging heat with the air flowing from the heat absorber to the radiator via the heat exchanger, and further cooled by the heat absorber. It dehumidifies by condensation in both heat absorbers. Further, the air whose temperature has risen after the radiator has been cooled by the first air blowing means is exhausted to the outside from the first exhaust port via the communicating means.

  That is, the rise in the room temperature can be reduced and the dehumidification efficiency can be improved. As a result, the comfort can be improved.

As shown in FIG. 1, the dehumidifying apparatus of the present embodiment has a substantially box-shaped body case 1, and a substantially square-shaped air inlet 2 is provided on the front side surface of the body case 1. A first exhaust port 3 having a substantially cylindrical shape is provided on the back side surface of 1, and a second exhaust port 4 having a substantially square shape is provided on the top surface near the back surface of the main body case 1. A heat pump 5 is provided in the main body case 1, and the heat pump 5 is formed by a compressor 6, a radiator 7, an expansion means 8, and a heat absorber 9 sequentially provided downstream of the compressor 6.

  A feature of this embodiment is that a heat exchanger 10 is provided in a space between the radiator 7 in the main body case 1 and the heat absorber 9, and the air sucked into the main body case 1 from the air inlet 2 is A first air blowing means 13 for blowing air to the first exhaust port 3 through one part; and a heat exchanger 10, a heat absorber 9, a heat exchanger 10, Second air blowing means 14 for blowing air to the second exhaust port 4 sequentially through the other part of the radiator 7 is provided, and the first exhaust port 3 is provided with a communication means 15 communicating with the outdoors. is there.

  Specifically, a heat exchanger 10 is provided between the heat absorber 9 and the radiator 7. In FIG. 2, the schematic of this heat exchanger 10 is shown. The heat exchanger 10 is formed such that a plurality of vertical air passages 11 communicating in the vertical direction and a plurality of horizontal air passages 12 communicating in the horizontal direction are alternately adjacent to each other. Here, the sensible heat of the air flowing through the adjacent vertical air passage 11 and the horizontal air passage 12 is exchanged.

  The first air blowing means 13 is provided in the air path between the radiator 7 and the first exhaust port 3, and the air sucked into the main body case 1 from the air inlet 2 by the first air blowing means 13 is disposed in the heat radiator. Then, the air is blown to the first exhaust port 3 through the upper radiator 7a which is one of the parts. The first exhaust port 3 includes communication means 15 that communicates with the outdoors. The communication means 15 is provided in the first exhaust port 3 and has a flexible hollow shape, communicates the main body case 1 and the outdoors, and is a cylindrical flexible pipe 15a that insulates the outer periphery of the pipe 15a. A portion of the heat insulating material 15b is wound. One end of the pipe 15a is connected to the first exhaust port 3, and the other end is taken out through a hole provided in the indoor wall, for example, a hole for air conditioner piping. Thus, when connecting the 1st exhaust port 3 of the main body case 1 and the outdoors, since it is the flexible pipe 15a, piping work can be performed easily and dew condensation in the pipe 15a can be suppressed. .

  A second air blowing unit 14 is provided in the air path between the radiator 7 and the second exhaust port 4, and the air blown into the main body case 1 from the air intake port 2 is heat exchanged by the second air blowing unit 14. The air is sent to the second exhaust port 4 through the vertical air passage 11 of the heat exchanger 10, the heat absorber 9, the horizontal air passage 12 of the heat exchanger 10, and the lower heat radiator 7 b which is the other part of the heat radiator 7.

  That is, in the dehumidifying operation, first, the refrigerant is made into a high-temperature and high-pressure gas state by the compressor 6, and the refrigerant flows to the radiator 7. By cooling the radiator 7 with room air blown by the first and second blowing means, the refrigerant is deprived of heat and liquefied. Next, the refrigerant liquefied by the radiator 7 is reduced to a low pressure by the expansion means 8 to make a gas-liquid two-layer state. Finally, the refrigerant in the gas-liquid two-layer state is caused to flow to the heat absorber 9. The second air blowing means is used to dehumidify the room air by dew condensation. Here, indoor air flows from the air inlet 2 to the heat absorber 9 through the vertical air passage 11 of the heat exchanger 10 by the second air blowing means 14, and the horizontal air passage 12 and the radiator 7 of the heat exchanger 10. Are exhausted from the second exhaust port 4 into the room sequentially. That is, the indoor air is first cooled by exchanging heat from the heat absorber 9 through the horizontal air passage 12 of the heat exchanger 10 to the radiator 7 and the vertical air passage 11 of the heat exchanger 10. Further, since it is further cooled by the heat absorber 9, it is dehumidified by condensation in both the heat exchanger 10 and the heat absorber 9. Further, the air whose temperature has risen due to the cooling of the radiator 7 by the first air blowing means 13 is exhausted to the outdoors from the first exhaust port 3 through the communication means 15.

  That is, the rise in the room temperature can be reduced and the dehumidification efficiency can be improved. As a result, the comfort can be improved.

  The air flowing from the heat exchanger 10 to the heat absorber 9 flows in from the upper surface portion 10 a of the heat exchanger 10 and flows out from the lower surface portion 10 b of the heat exchanger 10, so that the heat exchanger 10 and the heat absorber 9 The lower surface portion 10b of the heat exchanger 10 is inclined so that the heat absorber 9 side is on the upper side. Specifically, the heat exchanger 10 has a substantially vertically long rectangular parallelepiped shape, and is formed such that a plurality of vertical air passages 11 communicating in the vertical direction and a plurality of horizontal air passages 12 communicating in the horizontal direction are alternately adjacent to each other. Has been. As for the air flowing from the heat exchanger 10 to the heat absorber 9, first, the air sucked into the main body case 1 from the air inlet 2 flows in from the upper surface portion 10 a of the heat exchanger 10, and a plurality of vertical air passages 11. And flows out from the lower surface portion 10b of the heat exchanger 10. Next, it passes under the heat exchanger 10, passes under the heat absorber 9 disposed adjacent to the heat sink side surface portion 9 b on the downstream side of the heat exchanger 10, and passes through one side portion of the heat absorber 9, that is, the heat absorption. The heat sink 9 flows into the heat absorber 9 from the upstream heat absorber side surface portion 9a which is the upstream side of the air passage of the device 9. Here, the lower surface portion 10b of the heat exchanger 10 is inclined so that the heat absorber 9 side is on the upper side. That is, the lower surface portion 10 b of the heat exchanger 10 is inclined downward as it approaches the heat radiator 7 from the heat absorber 9.

  That is, the air flowing from the heat exchanger 10 to the heat absorber 9 flows out of the inclined lower surface portion 10b of the heat exchanger 10, so it flows in a substantially horizontal direction from a different position in the vertical direction, passes under the heat absorber 9, The heat sink 9 flows into the heat absorber 9 from the upstream side heat sink side surface portion 9a. Thereby, air becomes easy to flow out uniformly from the inclined lower surface portion 10b of the heat exchanger 10, and the air flows easily through the plurality of vertical air passages 11. As a result, the heat exchange efficiency between the air flowing from the heat absorber 9 to the radiator 7 via the horizontal air passage 12 of the heat exchanger 10 and the air flowing through the vertical air passage 11 of the heat exchanger 10 can be improved. .

  In addition, a drain pan 16 is provided below the heat exchanger 10 and the heat absorber 9, and the drain pan 16 is inclined so that the heat absorber 9 side is downward. Specifically, the drain pan 16 is inclined downward as it approaches the heat absorber 9 from the heat exchanger 10. That is, the heat exchanger 10 is inclined in the direction opposite to the inclined lower surface portion 10b. As a result, the distance between the drain pan 16 and the inclined lower surface portion 10 b of the heat exchanger 10 becomes larger as the distance from the radiator 7 to the heat absorber 9 is approached.

  That is, since the cross-sectional area of the air passage from the inclined lower surface portion 10b of the heat exchanger 10 to the heat absorber 9 is increased, the air passage resistance from the lower surface portion 10b of the heat exchanger 10 to the heat absorber 9 can be reduced.

  Further, a drain pan 16 is provided below the heat exchanger 10 and the heat absorber 9, and the drain pan 16 is substantially V-shaped. Specifically, the drain pan 16 located below the heat absorber 9 is inclined upward as it moves away from the heat exchanger 10 from between the heat absorber 9 and the heat exchanger 10, and is located below the heat exchanger 10. The drain pan 16 is inclined upward as it moves away from the heat absorber 9 from between the heat absorber 9 and the heat exchanger 10.

  That is, since the cross-sectional area of the air passage from the inclined lower surface portion 10b of the heat exchanger 10 to the space between the heat absorber 9 and the heat exchanger 10 increases, the air passage from the lower surface portion 10b of the heat exchanger 10 to the heat absorber 9 Resistance can be reduced, and the air passage that passes from between the heat absorber 9 and the heat exchanger 10 to the lower side of the heat absorber 9 and leads to the upstream heat absorber side surface portion 9a of the heat absorber 9 is gradually inclined upward. Therefore, it becomes easy to flow from the lower side of the heat absorber 9 to the upper side of the heat sink side surface portion 9 a of the upstream side of the heat absorber 9.

  Further, one part of the radiator 7 is located above the other part of the radiator 7, and the refrigerant pipe from the compressor 6 toward the radiator 7 is connected to the upper part of the one part of the radiator 7. is there. Specifically, the radiator 7 is formed of an upper radiator 7 a that is one part of the radiator 7 and a lower radiator 7 b that is the other part of the radiator 7. The upper radiator 7 a is located above the lower radiator 7 b and is provided in the air path between the air inlet 2 and the first blowing means 13. The refrigerant pipe from the compressor 6 toward the radiator 7 is connected to the upper part of the upper radiator 7 a which is one part of the radiator 7, and the refrigerant pipe from the radiator 7 toward the expansion means 8 is at the other part of the radiator 7. It is connected to the lower part of a certain lower radiator 7b.

  That is, the refrigerant pipe from the compressor 6 toward the radiator 7 is connected to the upper part of the upper radiator 7a, which is one part of the radiator 7, and the upper radiator 7a is higher in temperature than the lower radiator 7b. is there. Here, the air that has cooled the upper radiator 7a by the first air blowing means 13 is exhausted to the outside through the communication means 15 from the first exhaust port 3, so that the heat quantity of the radiator 7 can be efficiently exhausted. , Increase in the room temperature can be reduced.

  Further, the upper surface portion 10a of the heat exchanger 10 is located on the lower surface of the air passage from the air inlet 2 to one portion of the radiator 7, and the upper surface portion 10a is inclined so that the radiator 7 side is on the upper side. . Specifically, the upper surface portion 10a of the heat exchanger 10 is located on the lower surface of the air passage from the air inlet 2 to the upper radiator 7a that is one portion of the radiator 7, and the upper surface portion 10a of the heat exchanger 10 is As it approaches the radiator 7 from the heat absorber 9 from between the heat absorber 9 and the heat exchanger 10, it is inclined upward.

  That is, the indoor air is sent from the air inlet 2 to the upper surface portion 10a of the heat exchanger 10 through the plurality of vertical air passages 11 from the lower surface portion 10b of the heat exchanger 10 by the second air blowing means 14. Flowing into. Here, the upper surface portion 10a of the heat exchanger 10 is located on the lower surface of the air path from the intake port 2 to the upper radiator 7a of the radiator 7, and the upper surface portion 10a is located on the radiator 7 side above the heat absorber 9 side. Therefore, a part of the air flowing from the intake port 2 to the upper radiator 7a hits the entire upper surface portion 10a. For this reason, it becomes easy to flow from the upper surface part 10a of the heat exchanger 10 to the plurality of vertical air paths 11 more uniformly. As a result, the heat exchange efficiency between the air flowing from the heat absorber 9 to the radiator 7 via the horizontal air passage 12 of the heat exchanger 10 and the air flowing through the vertical air passage 11 of the heat exchanger 10 can be improved. .

  Further, the distance between the heat exchanger 10 and the heat absorber 9 is shorter than the distance between the heat exchanger 10 and the other part of the radiator 7. Specifically, the heat exchanger 10 is provided in the air path between the heat absorber 9 and the heat radiator 7, and heat exchange with the downstream heat absorber side surface portion 9 b that is the downstream side of the air path of the heat absorber 9. The distance from the upstream heat exchanger side surface portion 10c that is the upstream side of the horizontal air passage 12 of the horizontal air passage 12 is the downstream side surface portion of the downstream heat exchanger that is the downstream side of the horizontal air passage 12 of the heat exchanger 10 The distance between 10d and the upstream heat exchanger side surface portion 10c on the upstream side of the air path of the lower radiator 7b, which is the radiator 7, is shorter.

  That is, since the distance between the heat exchanger 10 and the heat absorber 9 is shorter than the distance between the heat exchanger 10 and the radiator 7, the heat exchanger 10 is affected by the heat from the heat absorber 9 than the radiator 7. Cheap. That is, the indoor air is cooled by exchanging heat from the heat absorber 9 to the radiator 7 via the horizontal air passage 12 of the heat exchanger 10 and the vertical air passage 11 of the heat exchanger 10. The heat exchanger 10 is further cooled by the cool air from the heat absorber 9, and as a result, the air passing through the vertical air passage 11 of the heat exchanger 10 can be cooled, condensed, and dehumidified.

  The heat exchanger 10 includes a plurality of vertical air passages 11 connected from the upper surface portion 10 a to the lower surface portion 10 b of the heat exchanger 10, and the cross-sectional area of the vertical air passage 11 on the radiator 7 side is vertical on the heat absorber 9 side. The configuration is larger than the cross-sectional area of the air passage 11. Specifically, the heat exchanger 10 has a plurality of vertical air passage portions 17 formed by adjoining a plurality of vertical air passages 11 in the front-rear direction of the main body case 1 in the left-right direction of the main body case 1. Between these adjacent vertical air passage portions 17, a horizontal air passage portion 18 in which a plurality of horizontal air passages 12 are formed adjacent to each other in the vertical direction of the main body case 1 is provided. Here, the cross-sectional area of the vertical air passage 11 on the rear surface side in the main body case 1 of the vertical air passage portion 17 of the vertical air passage portion 17 formed adjacent to the vertical air passage 11 in the front-rear direction in the main body case 1 is as follows. The main body case 1 has a configuration larger than the cross-sectional area of the vertical air passage 11 on the front surface side. That is, the cross-sectional area of the vertical air passage 11 on the radiator 7 side is larger than the cross-sectional area of the vertical air passage 11 on the heat absorber 9 side.

  That is, since the upper surface portion 10a and the lower surface portion 10b of the heat exchanger 10 are inclined, the length of the vertical air passage 11 on the radiator 7 side is longer than the length of the vertical air passage 11 on the heat absorber 9 side. The cross-sectional area of the vertical air passage 11 on the radiator 7 side is larger than the cross-sectional area of the vertical air passage 11 on the heat absorber 9 side, so that the vertical air path 11 on the heat radiator 7 side and the vertical wind on the heat absorber 9 side are The difference in the wind path resistance of the path 11 can be reduced, and it becomes easy to flow to the plurality of vertical wind paths 11 uniformly. As a result, the heat exchange efficiency between the air flowing from the heat absorber 9 to the radiator 7 via the horizontal air passage 12 of the heat exchanger 10 and the air flowing through the vertical air passage 11 of the heat exchanger 10 can be improved. .

  That is, the air blown into the main body case 1 from the air inlet 2 by the second air blowing means 14 is the vertical air passage 11 of the heat exchanger 10, the heat absorber 9, the horizontal air passage 12 of the heat exchanger 10, and the radiator 7. Then, the air is blown to the second exhaust port 4 through the lower radiator 7b and the second blowing means 14 in order. As for the air flowing from the vertical air passage 11 of the heat exchanger 10 to the heat absorber 9, first, the air sucked into the main body case 1 from the air inlet 2 flows in from the upper surface portion 10 a of the heat exchanger 10, It flows out from the lower surface portion 10 b of the heat exchanger 10 through the vertical air passage 11. Next, it passes under the heat exchanger 10, passes under the heat absorber 9 disposed adjacent to the downstream side heat sink side surface portion 9 b of the heat exchanger 10, and passes through the upstream side heat absorber side surface portion of the heat absorber 9. It flows into the heat absorber 9 from 9a. Here, since the central part of the suction port 14d of the second casing 14a which is the second air blowing means 14 is located above the center of the heat absorber 9, it passes under the heat absorber 9 and is upstream of the heat absorber 9. The air flowing into the side heat absorber side surface portion 9a can easily flow up to the upper portion of the heat absorber 9, and as a result, the air can easily flow to the heat absorber 9 uniformly.

  In addition, the heat exchanger 10 includes a plurality of horizontal air passages 12 connected from the upstream heat exchanger side surface portion 10 c to the downstream heat exchanger side surface portion 10 d of the heat exchanger 10, and the horizontal wind on the upper side of the heat exchanger 10. The cross-sectional area of the passage 12 is configured to be larger than the cross-sectional area of the horizontal air passage 12 on the lower side of the heat exchanger 10. Specifically, the heat exchanger 10 has a plurality of vertical air passage portions 17 formed by adjoining a plurality of vertical air passages 11 in the front-rear direction of the main body case 1 in the left-right direction of the main body case 1. Between these adjacent vertical air passage portions 17, a horizontal air passage portion 18 in which a plurality of horizontal air passages 12 are formed adjacent to each other in the vertical direction of the main body case 1 is provided. Here, the cross-sectional area of the horizontal air passage 12 on the upper surface side of the main body case 1 of the horizontal air passage portion 18 of the horizontal air passage portion 18 formed by adjoining the plurality of horizontal air passages 12 in the vertical direction in the main body case 1 is: The main body case 1 has a configuration larger than the cross-sectional area of the horizontal air passage 12 on the lower surface side. That is, the cross-sectional area of the horizontal air passage 12 on the upper side of the heat exchanger 10 is configured to be larger than the cross-sectional area of the horizontal air passage 12 on the lower side of the heat exchanger 10.
