  The problem in the conventional example is that the dehumidification efficiency is poor.

  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. Since the heat absorber is cooled, if indoor air is applied to the heat absorber, it can be condensed and dehumidified. Here, in order to raise the dehumidification efficiency in a heat absorber, it is necessary to cool a radiator efficiently.

  Therefore, by utilizing the fact that the dehumidified air dehumidified by the heat absorber is low in temperature, the cooling efficiency of the radiator has been improved by applying this low temperature dehumidified air to the radiator. Since it is warmed, the indoor temperature may increase due to the dehumidified air.

  Therefore, the present invention aims to reduce the rise in room temperature and improve the dehumidification efficiency.

  In order to achieve this object, the present invention includes a main body case that has an intake port and first, second, and third exhaust ports and is installed indoors, and a heat pump that is provided in the main body case. The heat pump is formed by a compressor and a radiator, an expansion unit, and a heat absorber sequentially provided downstream of the compressor, and the air sucked into the main body case from the air inlet is the heat absorber or the heat radiator. First air blowing means for blowing air to the first exhaust port through a part of the air, and the second exhaust gas through the part of the radiator for the air sucked into the main body case from the air intake port A second blowing means for blowing air to the opening or the third exhaust port, the first and second exhaust ports communicate with the main body case and the room, and the third exhaust port includes the A communication means for communicating the main body case with the outside, Air path switching means for switching the air path from the opening into the main body case to the second exhaust port or the third exhaust port via the radiator, the radiator and the first Humidifying means is provided between the two air blowing means, and the humidifying means is formed from a water storage case containing a certain amount of water and a humidifying filter containing water in the water storage case, The radiator is configured to be cooled, thereby achieving the initial purpose.

  As described above, the present invention includes an air inlet, a first, second, and third air outlet, a main body case installed indoors, and a heat pump provided in the main body case. Is formed by a compressor and a radiator, an expansion means, and a heat sink sequentially provided downstream of the compressor, and the air sucked into the main body case from the intake port is part of the heat absorber or the radiator. First air blowing means for blowing air to the first exhaust port, and air sucked into the main body case from the air inlet through the second exhaust port or the second through the radiator. A second blower means for blowing air to the three exhaust ports, the first and second exhaust ports communicate with the main body case and the room, and the third exhaust port has the main body case and the outdoors. Communicating means for communicating with the main body casing from the intake port. Air passage switching means for switching the air intake air into the second exhaust port or the third exhaust port via the radiator, and the radiator and the second air blowing means. The humidifying means is formed from a water storage case containing a certain amount of water and a humidifying filter containing water in the water storage case, and the radiator is formed by the water in the water storage case. Since it is configured to cool, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  That is, in the dehumidifying operation, first, the refrigerant is brought into a high-temperature and high-pressure gaseous state by the compressor, the refrigerant flows to the radiator, and by cooling the radiator, the refrigerant is deprived of heat and then liquefied. The refrigerant liquefied by the radiator is reduced to a low pressure by the expansion means to form a gas-liquid two-layer state. Finally, the refrigerant in the gas-liquid two-layer state is caused to flow to the heat absorber, and the room air is condensed on the heat absorber. By dehydrating, it is dehumidified. Here, when the refrigerant is cooled by the radiator, air is applied to the radiator, and the radiator is cooled by water in a water storage case that is a humidifying means. That is, the water in the water storage case that is humidified by the humidifying filter during humidification is used to cool the radiator during dehumidification. Thereby, the improvement of dehumidification efficiency can be aimed at. Furthermore, since the air that has cooled the radiator is exhausted from the third exhaust port to the outside through the communication means, an increase in the room temperature can be reduced.

  As a result, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  The heat pump 6 is formed by a compressor 10, a radiator 11, an expansion means 12, and a heat absorber 13 that are sequentially provided downstream of the compressor 10. As shown in FIG. 3, a compressor 10 is provided in the lower part of the main body case 1, a radiator 11 is provided in the central part, and a heat absorber 13 is provided in the upper part. The radiator 11 is formed of a bellows-like conduit portion 14 having a straight pipe portion in the horizontal direction and a plurality of fin portions 15 fixed to the conduit portion 14, and the refrigerant flows into the conduit portion 14 from the compressor 10. Flows from the lower part to the upper part of the radiator 11. Similarly, the heat absorber 13 is also formed of a bellows-like conduit portion 16 having a straight pipe portion in the horizontal direction and a plurality of fin portions 17 fixed to the conduit portion 16, and the expansion means 12 is provided in the conduit portion 16. The refrigerant flowing from the bottom flows from the lower part to the upper part of the heat absorber 13. Further, the surface area of the radiator 11 is larger than the surface area of the heat absorber 13.

  The air sucked into the main body case 1 from the air inlet 2 by the air blowing means 18 is blown to the air outlet 3 through the air purifying filter 8, the heat absorber 13, or a part of the heat radiator 11 as the air purifying means 7. Then, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 is sequentially supplied to the air outlet 4 or the air outlet 5 through a part of the air purifying filter 8 and the radiator 11 as the air purifying means 7. And is blown. Switching of the air path to the exhaust port 4 or the exhaust port 5 is performed by the air path switching unit 20, and the air path switching unit 20 is provided between the exhaust port 4, the exhaust port 5, and the air blowing unit 19. It is provided in the air passage.

  The air blowing means 18 is an air path between the heat absorber 13 and the exhaust port 3, faces the heat absorber 13, and is located below the heat absorber 13, and the air blowing means 19 includes the heat radiator 11, the exhaust port 4, and the exhaust port. 5 is located in the central portion of the radiator 11 so as to face the radiator 11.

  Humidification means 21 is provided between the radiator 11 and the blower means 19, and the humidification means 21 is formed from a water storage case 22 containing a certain amount of water and a humidification filter 23 containing water in the water storage case 22. is doing.

  With the above configuration, a humidifying operation and a dehumidifying operation are performed.

  First, in the humidifying operation, the heat pump 6 and the air blowing means 18 are stopped, the air path switching means 20 switches the air path to the exhaust port 4, and the air blowing means 19 sucks air into the main body case 1 from the air inlet 2. The blown air is blown from the exhaust port 4 into the room through a part of the radiator 11 and the humidifying filter 23. That is, the humidifying filter 23 which is the humidifying means 21 contains the water of the water storage case 22, so that this water gives moisture to the air blown by the blower means 19, and the air containing the moisture causes the room to pass through the room. It is to be humidified.

  The feature in this embodiment is that the radiator 11 is cooled by water in the water storage case 22 that is the humidifying means 21 during the dehumidifying operation.

  That is, in the dehumidifying operation, the heat pump 6 is operated, and the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 18 is the air purifying filter 8, the heat absorber 13 or the heat radiator 11 that is the air purifying means 7. The air is blown to the exhaust port 3 through a part of them. Here, the air blown to the heat absorber 13 is dehumidified by condensation in the heat absorber 13, the air blown to a part of the radiator 11 is warmed by the radiator 11, and these air are mixed together. The dehumidified air close to room temperature is blown into the room to dehumidify the room. On the other hand, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 is blown to the exhaust port 5 through a part of the radiator 11 and the humidifying filter 23. In this way, air is applied to the radiator 11 by the blower 19 to cool the radiator 11, and the radiator is cooled by the water in the water storage case 22 that is the humidifying means 21 (later using FIGS. 2 and 4). Will be described in detail). That is, the water in the water storage case 22 that contains the moisture in the humidifying filter during humidification is used to cool the radiator 11 during dehumidification. Thus, the dehumidification efficiency can be improved by increasing the cooling efficiency of the radiator 11.

  Further, the air that has cooled the radiator 11 is exhausted from the exhaust port 5 to the outside through the communication unit 9 by switching the air path to the exhaust port 5 by the air path switching unit 20. Can be reduced.

  As a result, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  In this way, not only is air applied to the radiator 11, but also the radiator is cooled by the water in the water storage case 22 that is the humidifying means 21, thereby reducing an increase in indoor temperature and improving dehumidification efficiency. It is something that can be done.

  Here, the humidifying means 21 will be described in detail. The humidifying means 21 includes a water storage case 22 containing a certain amount of water, and a disc-shaped humidifying filter 23 in which a part of the peripheral edge is immersed in the water of the water storage case 22. And a water supply unit 24 that pumps water from the water storage case 22 to the humidifying filter 23 and supplies the water. The water supply unit 24 serving as the humidifying means 21 draws water from the water storage case 22 and supplies it to the radiator 11.

  Specifically, the water storage case 22 has a substantially box shape with an upper surface opened and contains a certain amount of water supplied from a water supply tank (not shown). The water storage case 22 is rotatable. The water supply part 24 is installed in. As shown in FIG. 4, the water supply portion 24 is formed of a first frame body portion 25, a second frame body portion 26, and a water supply case portion 27. The first frame body portion 25 is provided with a rotation shaft portion 28 serving as a center of rotation at the center portion and a plurality of water supply case fixing portions 29 for fixing the water supply case portion at the peripheral portion, and the rotation shaft portion 28. The plurality of water supply case fixing portions 29 are connected by linear and circular crosspieces 30. The second frame body part 26 is provided with a rotation shaft part 31 serving as a center of rotation at the center part, and a cylindrical peripheral edge holding part 32 fitted to the peripheral edge part of the first frame body part 25 at the peripheral part. The rotating shaft part 31 and the peripheral edge holding part 32 are connected by a linear and circular bar part 33. The water supply case portion 27 has a substantially box shape having an opening 34 that is open on one side, and is fixed to a water supply case fixing portion 29 of the first frame body portion 25, and the first frame body portion 25 is a rotating shaft portion. By rotating about 28, the water in the water storage case 22 is pumped up at the lowest point, and the water is blown toward the humidifying filter 23 and the radiator 11 at the highest point. The humidifying filter 23 has a disc shape formed of a plurality of fibers and is fixed between the first frame body portion 25 and the second frame body portion 26.

  With such a configuration, the humidifying filter 23 is fixed between the first frame body part 25 to which the plurality of water supply case parts 27 that are the water supply parts 24 are fixed and the second frame body part 26 that is the water supply part 24. Then, by rotating by a rotating means (not shown), the water supply case portion 27 pumps up the water in the water storage case 22 at the lowest point, and the water in the water supply case portion 27 at the uppermost point, and the humidifying filter 23 and Water is poured over the radiator 11 to supply water.

  That is, the water supply unit 24 can supply water to both the humidifying filter 23 and the radiator 11.

  The radiator 11 is provided below the heat absorber 13. Specifically, the compressor 10 is provided in the lower part in the main body case 1, the radiator 11 is provided in the center part, and the heat absorber 13 is provided in the upper part. That is, since the refrigerant flows in the order from the compressor 10, that is, the compressor 10, the radiator 11, and the heat absorber 13, the compressor 10 and the radiator 11, and the connection between the radiator 11 and the heat absorber 13 are arranged. Since a piping part can be shortened, the heat loss in a connection piping part can be suppressed.

  The radiator 11 is formed of a bellows-like conduit portion 14 and a plurality of fin portions 15 fixed to the conduit portion 14, and the refrigerant flowing from the compressor 10 into the conduit portion 14 is below the radiator 11. The heat absorber 13 is formed of a bellows-like conduit portion 16 and a plurality of fin portions 17 fixed to the conduit portion 16, and the refrigerant flowing from the compressor 10 into the conduit portion 16 is: The heat sink 13 is configured to flow from the lower part to the upper part.

  That is, since the connecting piping part is provided between the upper part of the radiator 11 and the lower part of the heat absorber 13, and the connecting pipe part between the radiator 11 and the heat absorber 13 can be shortened, the heat loss in the connecting pipe part Can be further suppressed.

  Further, the surface area of the radiator 11 is larger than the surface area of the heat absorber 13. Specifically, the radiator 11 and the heat absorber 13 have substantially the same horizontal and horizontal dimensions with respect to the main body case 1, but the vertical dimension of the radiator 11 is larger than that of the heat absorber 13. It is. That is, since the space | interval of the horizontal straight pipe parts which are the bellows-shaped conduit | pipe parts 14 of the heat radiator 11 becomes large, and an opening area becomes large, the air path resistance in the heat radiator 11 becomes small. Thereby, at the time of humidification, the air path resistance of the humidified air path that is blown from the intake port 2 to the exhaust port 4 or the exhaust port 5 through the air cleaning filter 8 and part of the radiator 11 in order is reduced. Humidification ability can be improved.

  Further, the water supply unit 24 which is the humidifying means 21 is configured to draw up water from the water storage case 22 and supply it to the lower part of the radiator 11. Specifically, at the time of dehumidification, the water pumped up by the water supply case part is supplied slightly below the center part of the radiator 11. This is because the refrigerant flowing from the compressor 10 flows from the lower part to the upper part of the conduit part 14 of the radiator 11, so that water is supplied to the part where the temperature of the radiator 11 is high.

  Thereby, the radiator 11 can be efficiently cooled.

  Further, the air blowing means 18 is configured to be positioned below the heat absorber 13. Specifically, the air blowing means 18 is formed by a fan casing 35, an electric motor 36 disposed in the fan casing 35, and blades 37 that are rotated by the electric motor 36. The fan casing 35 includes a suction port 38 on the front surface side of the main body case 1 and a discharge port 39 on the top surface side of the main body case 1. The suction port 38 is located below the heat absorber 13. Here, since the refrigerant flowing from the expansion means 12 flows from the lower part to the upper part of the conduit part 16 of the heat absorber 13, the room air is supplied to the part where the temperature of the heat absorber 13 is low.

  Thereby, the dehumidification efficiency in the heat absorber 13 can be improved.

  Moreover, the control means 40 which changes the calorie | heat amount of the heat pump 6 is provided. Specifically, the control means 40 can perform three types of switching when the heat pump 6 is stopped, a weak notch with a small amount of heat, and a strong notch with a large amount of heat. First, at the time of dehumidification, the control means 40 operates the heat pump 6 with a strong notch with a large amount of heat to perform dehumidification. On the other hand, at the time of humidification, two types of humidification can be performed, when the heat pump 6 is stopped and when the heat pump 6 is operated with a weak notch with a small amount of heat. Here, when the heat pump 6 has a weak notch smaller than the strong notch at the time of dehumidification, the heat amount of the heat absorber 13 is such that no condensation occurs when indoor air in winter is supplied to the heat absorber 13. The amount of heat. When humidified in this state, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 passes through the air purifying filter 8 which is the air purifying means 7, a part of the radiator 11 and the humidifying means 21 sequentially. The air is blown from the exhaust port 4 into the room. Here, the air supplied to the humidifying means 21 is a weak notch in which the heat amount of the heat pump 6 is small, but since the air is warmed by the radiator 11 and is in a state where the relative humidity is low at high temperature, humidification containing water is included. The amount of moisture released from the filter 23 is increased, and the humidifying ability can be improved. When the heat pump 6 is stopped, the air blowing means 18 is also stopped, the air path switching means 20 switches the air path to the exhaust port 4, and the air blowing means 19 causes the air inlet 2 to enter the main body case 1. The sucked air is blown from the exhaust port 4 into the room through a part of the radiator 11 and the humidifying filter 23. That is, the humidifying filter 23 which is the humidifying means 21 contains the water of the water storage case 22, so that this water gives moisture to the air blown by the blower means 19, and the air containing the moisture causes the room to pass through the room. It is to be humidified. Thus, since the heat pump 6 and the air blowing means 18 are stopped, the humidification amount is inferior to that when the heat pump 6 is operated with a weak notch with a small amount of heat, but the humidifying operation in the energy saving mode can be performed.

  Further, the humidifying means 21 is configured to be positioned below the radiator 11. Specifically, it fixed between the 1st frame body part 25 which fixed the some water supply case part 27 which is the water supply part 24 of the humidification means 21, and the 2nd frame body part 26 which is the water supply part 24. The humidifying filter 23 is provided at a position facing the lower part of the radiator 11. That is, the radiator 11 is formed of a bellows-like conduit portion 14 and a plurality of fin portions 15 fixed to the conduit portion 14, and the refrigerant flowing from the compressor 10 into the conduit portion 14 is below the radiator 11. Therefore, the air that has passed through the portion where the temperature of the radiator 11 is high is mainly supplied to the humidifying filter 23. That is, since the air having a higher temperature and lower relative humidity is supplied to the humidifying filter 23, the amount of moisture released from the humidifying filter 23 containing water is increased, and the humidifying ability can be improved. .

  Moreover, the 2nd ventilation means is set as the structure located in the lower part of a heat radiator. Specifically, the air blowing means 19 is formed of a fan casing 41, an electric motor 42 disposed in the fan casing 41, and blades 43 that are rotated by the electric motor 42. The fan casing 41 includes a suction port 44 on the front surface side of the main body case 1 and a discharge port 45 on the top surface side of the main body case 1. The second suction port 44 is provided at a position facing the humidifying filter 23 which is the humidifying means 21 below the radiator 11. That is, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 is the air purifying filter 8 that is the air purifying means 7, the portion where the temperature of the radiator 11 that is the lower part of the radiator 11 is high, the humidifying means The air is sent to the exhaust port 4 or the exhaust port 5 through the humidifying filter 23 which is 21 in order. Here, since the part where the temperature of the radiator 11 which is the lower part of the radiator 11 is high and the humidifying filter 23 which is the humidifying means 21 are positioned substantially in a straight line, the air path resistance is reduced and the humidifying ability is improved. I can do it.

  Moreover, the water storage case 22 which is the humidification means 21 is a substantially box shape, and the upper surface is opened, The upper end part of this opening is the structure located below the lower end part of the heat radiator. That is, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 19 passes through the air purifying filter 8 as the air purifying means 7, the radiator 11, and the humidifying means 21 in order, and then the air outlet 4 or the air outlet 5. It is blown into. Here, when air is sent from the radiator 11 to the humidifying means 21, the upper end of the water storage case 22 located on the upstream side and the downstream side of the humidifying filter 23, which is the humidifying means 21, is a radiator. 11, the water storage case does not protrude from the air passage from the humidifying means 21 to the humidifying filter 23. As a result, the water storage case 22 does not have wind path resistance, so that the humidifying ability can be improved.

  The main body case 1 has a substantially box shape, and the exhaust port 3 and the exhaust port 4 are provided adjacent to the top surface of the main body case 1. Specifically, the exhaust port 4 is a substantially horizontally long rectangular opening located on the top surface on the rear side in the front-rear direction of the main body case 1. The exhaust port 3 is a substantially horizontally long rectangular opening located on the front side of the exhaust port 4 in the front-rear direction of the main body case 1. Thus, when the exhaust port 3 and the exhaust port 4 are adjacent to each other, when the heat amount of the heat pump 6 is humidified with a small notch, the air cooled by the heat absorber 13 blown from the exhaust port 3; The air heated by a part of the radiator 11 is mixed with the air having a temperature lower than the room temperature and the air blown from the exhaust port 4. The air is heated by a part of the radiator 11 and is humidified by the humidifying means 21. When air having a temperature higher than room temperature is mixed, the temperature is close to room temperature, and an increase in room temperature during humidification can be suppressed.

  Moreover, as shown in FIG. 5, the communication means 9 which connects the main body case 1 and the outdoors is a flexible hollow pipe 46. Specifically, the communication means 9 is a cylindrical flexible pipe 46 that is provided in the exhaust port 5 and has a flexible hollow shape that connects the main body case 1 and the outside. One end of the pipe 46 is connected to the exhaust port 5 and the other end is taken out through a hole provided in the indoor wall, for example, a hole for air conditioning piping. Thus, when communicating the exhaust port 5 of the main body case 1 and the outdoors, since it is the flexible pipe 46, the piping work can be easily performed.

  The communication means 9 is provided with a heat insulating portion on the outer peripheral portion. Specifically, a heat insulating material 47 that is a heat insulating portion is wound around the outer peripheral portion of the pipe 46 that is the communication means 9. Thereby, dew condensation in the pipe 46 can be suppressed.

  Further, the air purifying means 7 is provided between the air inlet 2 and the radiator 11 and the heat absorber 13. As a result, indoor air is blown from the intake port to the radiator 11 and the heat absorber 13 via the air cleaning means 7, so that air purification can be performed while humidifying and dehumidifying.

  As described above, the present invention includes an air inlet, a first, second, and third air outlet, a main body case installed indoors, and a heat pump provided in the main body case. Is formed by a compressor and a radiator, an expansion means, and a heat sink sequentially provided downstream of the compressor, and the air sucked into the main body case from the intake port is part of the heat absorber or the radiator. First air blowing means for blowing air to the first exhaust port, and air sucked into the main body case from the air inlet through the second exhaust port or the second through the radiator. A second blower means for blowing air to the three exhaust ports, the first and second exhaust ports communicate with the main body case and the room, and the third exhaust port has the main body case and the outdoors. Communicating means for communicating with the main body casing from the intake port. Air passage switching means for switching the air intake air into the second exhaust port or the third exhaust port via the radiator, and the radiator and the second air blowing means. The humidifying means is formed from a water storage case containing a certain amount of water and a humidifying filter containing water in the water storage case, and the radiator is formed by the water in the water storage case. Since it is configured to cool, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  That is, in the dehumidifying operation, first, the refrigerant is brought into a high-temperature and high-pressure gaseous state by the compressor, the refrigerant flows to the radiator, and by cooling the radiator, the refrigerant is deprived of heat and then liquefied. The refrigerant liquefied by the radiator is reduced to a low pressure by the expansion means to form a gas-liquid two-layer state. Finally, the refrigerant in the gas-liquid two-layer state is caused to flow to the heat absorber, and the room air is condensed on the heat absorber. By dehydrating, it is dehumidified. Here, when the refrigerant is cooled by the radiator, air is applied to the radiator, and the radiator is cooled by water in a water storage case that is a humidifying means. That is, the water in the water storage case that is humidified by the humidifying filter during humidification is used to cool the radiator during dehumidification. Thereby, the improvement of dehumidification efficiency can be aimed at. Furthermore, since the air that has cooled the radiator is exhausted from the third exhaust port to the outside through the communication means, an increase in the room temperature can be reduced.

  As a result, it is possible to reduce the rise in the room temperature and improve the dehumidification efficiency.

  Therefore, utilization as an air conditioner for home use or office use is expected.
