  The problem in the conventional example is that the dehumidifying ability is low.

  That is, in the conventional product, the indoor air is condensed by the heat absorber and thereby dehumidification is performed, but the indoor air is supplied to the heat absorber as it is. Cannot be put into a state where it is easy to condense (increasing the water content or increasing the relative humidity), and there has been a limit to improving the dehumidifying ability. Further, when the room temperature is low as in winter, frost adheres to the heat absorber (frosting state), so that the operation is performed while defrosting, and the dehumidifying ability is significantly reduced. Furthermore, since the absolute amount of moisture contained in the air is small, there is a limit to the dehumidifying ability, and as a result, the dehumidifying ability could not be improved.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIG. 1, the dehumidifying device of the present embodiment includes a main body case 3 having a first air inlet 1, a second air inlet 1 </ b> A and an air outlet 2, and a heat pump 4 provided in the main body case 3. It has.

  The heat pump 4 is formed by a compressor 5, a radiator 6, an expansion means 7, and a heat absorber 8 that are sequentially connected downstream of the compressor 5 by a pipe line 13.

  The air sucked into the main body case 3 from the first air inlet 1 which is the first air passage 14 by the air blowing means 9 is blown to the air outlet 2 through the heat radiator 6 and the heat absorber 8 in order.

  The feature of the present embodiment is that the air sucked into the main body case 3 from the second air inlet 1A which is the second air passage 15 by the air blowing means 9 is blown to the air outlet 2 via the heat absorber 8, A moisture releasing portion 11 of the dehumidifying rotor 10 is provided between the radiator 6 and the heat absorber 8 in the first air passage 14, and the moisture absorbing portion 12 of the dehumidifying rotor 10 is connected to the first air passage 14 and the second air blowing. A heater 11A is provided between the heat absorber 8 of the passage 15 and the exhaust port 2, a heater 11A is provided between the radiator 6 of the first air passage 14 and the moisture release portion 11 of the dehumidification rotor 10, and the second air passage. That is, the precooling means 16 is provided between the 15 second air inlets 1 </ b> A and the heat absorber 8.

  That is, the refrigerant pressurized by the compressor 5 is sent to the radiator 6, where the air sucked into the main body case 3 from the first air inlet 1 is heated. Next, the refrigerant that has passed through the radiator 6 reaches the expansion means 7, and then returns to the compressor 5 via the heat absorber 8 and then the precooling means 16.

  First, the air heated by the radiator 6 is then heated by the heater 11A, and then passes through the moisture release portion 11 of the dehumidification rotor 10 where the moisture from the moisture release portion 11 is taken away. The air in the state is blown by the blowing means 9 immediately before the heat absorber 8.

  Moreover, in this embodiment, while providing the 2nd ventilation path 15 which ventilates the air inhaled in the main body case 3 from the 2nd inlet port 1A to the exhaust port 2 via the heat absorber 8, it is 2nd. The air passage 15 is in a portion where the pre-cooling means 16 is provided. Thereby, the air sucked into the main body case 3 from the second air inlet 1 </ b> A is cooled by the precooling means 16, and the low-temperature air is blown by the blower means 9 immediately before the heat absorber 8.

  Next, the air in the high temperature and high humidity state of the first air passage 14 and the air in the low temperature state of the second air passage 15 are mixed just before the heat absorber 8, and the first air passage 14. This air is cooled by the air in the second air passage 15 and is blown to the heat absorber 8.

  Here, the air mixed just before the heat absorber 8 is condensed by the heat absorber 8 and dehumidified.

  This condensed water is stored in the drain pan 17. The drain pan 17 is provided below the heat absorber 8 and the precooling means 16.

  The air that could not be dehumidified by the heat absorber 8 becomes a low temperature by the heat absorber 8, but the relative humidity is extremely high although the temperature is low. The low-temperature air having a high relative humidity will then pass through the moisture absorbing portion 12 of the dehumidifying rotor 10, and this moisture absorbing portion 12 is rotated by the driving means 18 so that the upper portion of FIG. Since the moisture is already released in the moisture release portion 11 and the humidity is low, moisture can be absorbed from the air having a relatively high relative humidity despite the low temperature.

  For these reasons, the dehumidifying device of the present embodiment can have a very high dehumidifying effect.

  Now, the pre-cooling means 16 will be described in more detail. The pre-cooling means 16 of the present embodiment is constituted by a part of the pipe line 13 between the heat absorber 8 and the compressor 5.

  As a result, the cool air that has been heated by the heat absorber 8 but still remains is added to the air sucked into the main body case 3 from the second air inlet 1 </ b> A, so that the cooled air is transferred to the heat absorber 8. It will be blown.

  That is, the air sucked into the main body case 3 from the second air inlet 1A is cooled using the cold heat of the refrigerant. Therefore, the refrigerant warmed by the pre-cooling means 16 is sent to the compressor 5, and the efficiency in the compressor 5 is increased. As a result, the temperature of the radiator 6 rises, and the air heated by the radiator 6 Is heated by the heater 11 </ b> A, and then passes through the moisture release portion 11 of the dehumidifying rotor 10. From these things, it can be set as the extremely high dehumidification effect.

  Further, the pre-cooling means 16 is a pipe line portion 13 </ b> A in the vicinity of the heat absorber 8.

  As a result, the pre-cooling means 16 is configured by the pipe portion 13A of the refrigerant having the lowest temperature in the process in which the refrigerant is sent from the heat absorber 8 to the compressor 5 in the pipe line 13, and the cold air is supplied to the air sucked into the main body case 3. It will be added. Therefore, since the air is blown to the hygroscopic portion 12 of the dehumidification rotor 10 through the heat absorber 8 in a state where the relative humidity is more likely to cause dew condensation, the dehumidification effect can be further enhanced.

  Further, the precooling means 16 is located in the vicinity of the heat absorber 8.

  Thus, the pre-cooling means is obtained by adding cold heat to the air sucked into the main body case 3 from the second air inlet 1A by the pre-cooling means 16 and blowing the air to the adjacent heat absorber 8 in a state of high relative humidity where condensation is likely to occur. Since the air temperature is suppressed from increasing while the air is blown from 16 to the heat absorber 8, the air can be blown. As a result, the dehumidifying effect can be further increased.

  The pre-cooling means 16 is located below the heat absorber 8.

  Thereby, since the dew condensation water condensed by the heat absorber 8 flows through the pipe line 13 to the pre-cooling means 16, the dew condensation water collects in the pre-cooling means 16, so that the dew condensation water can be easily collected.

  The precooling means 16 is positioned on a straight line in the direction perpendicular to the heat absorber 8.

  Thereby, the dew condensation water condensed by the heat absorber 8 flows easily through the pre-cooling means 16 through the pipe line 13, and further, while the dew condensation water condensed by the heat absorber 8 flows through the pipe line 13 to the pre-cooling means 16. Even if it is dropped, the condensed water collects in the pre-cooling means 16, and therefore the condensed water can be easily collected.

(Embodiment 2)
In FIG. 2, the same components as those in FIG.

  As shown in FIG. 2, the dehumidifying device of this embodiment has a shape in which the pre-cooling means 16A bends the pipe line 13 into a wave shape. Specifically, the pre-cooling means 16A has a shape in which the pipe 13 is bent into a wave shape from the leeward side of the second air passage 15 to the windward side, and the pipe 13 on the heat absorber 8 side is the leeward side. .

  That is, in the pre-cooling means 16A in which the pipe 13 is bent into a wave shape, since the leeward side of the second air passage 15 is on the heat absorber 8 side, the temperature of the leeward refrigerant is lower, and the leeward side is lower than the leeward side. Temperature rises. Therefore, the air sucked into the main body case 3 from the second air inlet 1A is efficiently cooled because the air gradually comes into contact with the low temperature pipe line 13 from the high temperature refrigerant line 13. As a result, a higher dehumidifying effect can be obtained.

  Further, since the pre-cooling means 16A has a shape in which the pipe 13 is bent into a wave shape, the vibration generated in the compressor 5 is absorbed by the expansion and contraction of the wave shape of the pipe 13 and is transmitted to the heat absorber 8. Vibration is reduced.

  Thereby, the vibration generated in the compressor 5 is suppressed from being transmitted to the heat absorber 8.

(Embodiment 3)
In FIG. 3, the same components as those in FIG.

  As shown in FIG. 3, in the dehumidifying device of the present embodiment, the precooling means 16 </ b> B is provided with the radiation fins 19 outside the pipe line.

  Thereby, since cold heat is added to the air sucked into the main body case 3 from the second air inlet 1A by the radiating fins 19 of the pre-cooling means 16B, the contact area is increased by the radiating fins 19, and the main body case is more efficiently operated. The cold air is added to the air sucked into the air.

  Therefore, since the air is blown to the hygroscopic portion 12 of the dehumidification rotor 10 through the heat absorber 8 in a state where the relative humidity is more likely to cause dew condensation, the dehumidification effect can be further enhanced.

  As described above, the present invention includes a main body case having first and second intake ports and an exhaust port, and a heat pump provided in the main body case. The heat pump includes a compressor and a downstream of the compressor. Are formed by a radiator, an expansion means, and a heat absorber, which are sequentially connected to each other by pipes, and the air sucked into the main body case from the first intake port to the exhaust port via the heat radiator and the heat absorber in turn. A first air passage that blows air, a second air passage that blows air that has been sucked into the main body case from the second air inlet into the exhaust port via the heat absorber, and these first and second air passages. In addition to providing air blowing means for blowing air to the air passage, a moisture releasing portion of the dehumidifying rotor is provided between the radiator and heat absorber of the first air passage, and the moisture absorbing portion of the dehumidifying rotor is the first and second Provided between the heat absorber of the air passage and the exhaust port, and the heat radiator of the first air passage A heater is provided between the moisture release part of the wet rotor, and a pre-cooling means is provided between the second air inlet of the second air passage and the heat absorber, so that the dehumidifying ability can be improved. Is.

  That is, in the present invention, a moisture release portion of the dehumidification rotor is provided between the radiator and the heat absorber of the first air passage, and the moisture absorption portion of the dehumidification rotor is the heat absorber and the exhaust port of the first and second air passages. Since the heater is provided between the radiator of the first air passage and the moisture release part of the dehumidifying rotor, the heater of the dehumidifying rotor can be used with the heater even in winter when the room temperature is low. By heating the passing air, a large amount of water is evaporated from the moisture releasing section and then blown to the heat absorber.

  In addition to such a configuration, in the present invention, a second air passage that blows air sucked into the main body case from the second air inlet into the exhaust port via the heat absorber is provided, and the second air passage is provided in the second air passage. Since the pre-cooling means is provided, the air sucked into the main body case from the second air inlet is cooled by the pre-cooling means, and the cooled air is blown to the heat absorber.

  From these things, the air of said 1st ventilation path and the 2nd ventilation path mixes in front of a heat sink, and the air of the 1st ventilation path is cooled by the air of the 2nd ventilation path, thereby The air is blown to the heat absorber in a state where the relative humidity is high. Then, it is dehumidified by further cooling and dew condensation by the heat absorber, and finally dehumidifying at the moisture absorption part of the dehumidification rotor by blowing it to the dehumidification rotor in a state where it is easy to condense with high relative humidity even at a low temperature. As a result, the dehumidifying ability can be improved.

  Therefore, it is expected to be utilized as a dehumidifying device for home use or office use.
