Japanese Patent Laid-Open No. 6-331167

  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 brought into a state where it is easy to condense (increasing the water content, 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.

  Therefore, an object of the present invention is to improve the dehumidifying ability.

  And in order to achieve this object, the present invention comprises a main body case having first and second air inlets and exhaust ports, and a heat pump provided in the main body case, the heat pump comprising: a compressor; It is formed by a radiator, expansion means, and heat sink sequentially provided downstream of the compressor, and air sucked into the main body case from the first intake port is blown to the exhaust port through the radiator and heat absorber in sequence. A first air passage, 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, and these first and second air passages In addition, a dehumidifying rotor is provided between the radiator and the heat absorber of the first air passage, and the dehumidifying rotor has a moisture absorbing portion that is disposed between the first and second air blowers. Provided between the heat sink of the passage and the exhaust port, heat radiation of the first air passage A heater between the moisture releasing section of the dehumidifying rotor provided with the provided air flow rate adjusting means to the second air passage, thereby it is to achieve the intended purpose.

  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. A first heat radiator, an expansion means, and a heat absorber, and the air sucked into the main body case from the first air intake port is blown to the exhaust port through the heat radiator and the heat absorber in turn. To blow the air that has been sucked into the main body case from the second air inlet to the air outlet through the heat absorber and the first and second air passages. A dehumidifying rotor is provided between the radiator and the heat absorber of the first air passage, and the moisture absorbing portion of the dehumidifying rotor is the heat absorber of the first and second air passages. Between the air outlet and the exhaust port, the radiator of the first air passage and the dehumidifying rotor A heater provided between the wet part, said the second air passage having thereon a flowing amount adjusting means, in which it is possible to improve the dehumidification capacity.

  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 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 dehumidification rotor, it is provided between the exhaust ports. By heating the air that passes through the radiator, a large amount of moisture can be evaporated from the moisture release section, and then this large amount of moisture can be condensed by the heat absorber. Can do it.

  In addition, the air after the dew condensation by the heat absorber reaches the moisture absorption part of the dehumidification rotor, and as described above, the moisture absorption part is heated by the heater in the moisture release part and becomes dry. Therefore, moisture contained therein can be sufficiently absorbed even in a low temperature state.

  And in addition to such a configuration, in the present invention, the first air passage that blows the air sucked into the main body case from the first air inlet to the exhaust port via the heat sink and the heat absorber, and Since the second air passage for blowing the air sucked into the main body case from the second air inlet to the exhaust port via the heat absorber is provided, and the air volume adjusting means is provided in the second air passage, In addition to the use of the first air passage, the second air passage can be used by adjusting the air passage, so that, for example, the optimum dehumidifying operation can be performed for each season of spring, summer, autumn and winter.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the dehumidifying device of this embodiment includes a main body case 3 having an intake port 1 and an exhaust port 2, and a heat pump 4 provided in the main body case 3.

  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 provided downstream of the compressor 5.

  Air is sucked into the main body case 3 from the suction port 1 by the blower 9, and the sucked air is then blown to the exhaust port 2 through the radiator 6 and the heat absorber 8 in order.

  The present embodiment is characterized in that the air passage of the blowing means 9 is provided with a moisture releasing portion 11 of the dehumidifying rotor 10 between the radiator 6 and the heat absorber 8, and the moisture absorbing portion 12 of the dehumidifying rotor 10 is the heat absorber 8. Provided between the air outlet 2 and the exhaust port 2, and the heater 11 A is interposed between the radiator 6 of the air passage and the moisture releasing portion 11 of the dehumidifying rotor 10, and further below the air inlet 1 of the main body case 3. And the air volume adjusting means 13 is interposed in the air passage extending from the air inlet 1A to the heat absorber 8.

  That is, the refrigerant pressurized by the compressor 5 is sent to the radiator 6 where the air taken into the main body case 3 from the intake port 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.

  The air heated by the radiator 6 is then heated by the heater 11 </ b> A, and then passes through the moisture release portion 11 of the dehumidifying rotor 10, where the moisture from the moisture release portion 11 is taken away to the heat absorber 8. Will flow.

  Here, first, the air that has passed through the moisture release portion 11 of the dehumidifying rotor 10 is condensed in the heat absorber 8, and this condensed water is stored in the water storage tank 14.

  Now, the air that has passed through the heat absorber 8 is cooled to a low temperature by the heat absorber 8, but the humidity is extremely high although the temperature is low. This low-temperature air containing high humidity then passes through the hygroscopic section 12 of the dehumidifying rotor 10, and this hygroscopic section 12 is driven to rotate by the drive means 15 so that the upper part of FIG. Since the moisture is already released at the moisture releasing portion 11 and the humidity is low, the moisture can be absorbed from the air having a very high humidity despite the low temperature.

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

  In the present embodiment, as described above, the first air passage from the air inlet 1 to the air outlet 2 and the second air passage from the air inlet 1A to the air outlet 2 are provided and the second air passage is provided. The air volume adjusting means 13 is interposed.

  In such a configuration, for example, an operation mode according to the season will be described with reference to FIG.

  First, in the rated dehumidification mode, the compressor 5, the air blowing means 9, and the driving means 15 are turned on, the heater 11A is turned off, and the air volume adjusting means 13 is brought into a small opening state.

  That is, since the air volume adjusting means 13 has a three-step staircase shape as shown in FIG. 3 and is configured to rotationally drive the staircase-shaped body, the air passage from the air inlet 1A to the heat absorber 8 has a small opening, a middle opening, It can be switched to a large opening or fully closed state. First, in this rated dehumidification mode, a small opening state is set. As a result, the heat absorber 8 passes the air passing through the dehumidifying portion 11 of the dehumidifying rotor 10 from the intake port 1 and the dehumidifying portion 11 of the dehumidifying rotor 10 passing through the air volume adjusting means 13 from the intake port 1A. Air that has not been supplied will be supplied.

  That is, the reason why air that does not pass through the radiator 6 and the dehumidifying rotor 10 is supplied to the heat absorber 8 from the intake port 1A in this manner is that the moisture absorption region of the dehumidifying rotor 10 is compared with the case where air is not supplied from the intake port 1A. This is because the amount of moisture absorbed by the dehumidifying rotor 10 is increased and the dehumidifying capacity is improved by increasing the passing air volume.

  In this case, since the heater 11A is OFF, the moisture dehumidifying capacity of the dehumidifying rotor 10 is reduced. Therefore, due to the balance of moisture absorption and desorption of the dehumidifying rotor 10, the supply of air from the intake port 1A is performed when the heater 11A is turned on. There is an optimum mixing amount where the amount is small.

  In this mode, the necessary dehumidifying ability can be obtained with energy saving.

  Next, in the powerful clothes drying mode when it is desired to quickly dry the clothes, the compressor 5, the air blowing means 9, and the driving means 15 are turned on, the heater 11A is also turned on, and the air volume adjusting means 13 is opened. . Thus, when it is desired to dry clothes quickly, if the heater 11A is turned on and the air volume adjusting means 13 is in a large opening state, the air supplied from the radiator 6 to the moisture releasing portion 11 of the dehumidifying rotor 10 is heated. Air that has not passed through the moisture release portion 11 of the dehumidifying rotor 10 that has passed through the air volume adjusting means 13 from the intake port 1A is supplied with a large air volume.

  That is, the reason why a large amount of air that does not pass through the radiator 6 and the dehumidifying rotor 10 is supplied from the intake port 1A to the heat absorber 8 is that the amount of air that passes through the heater 11A compared to the case where air is not supplied from the intake port 1A. Is decreased and the temperature of the heater 11A is increased, the amount of moisture released from the dehumidifying rotor 10 is increased, and further, the amount of air passing through the moisture absorbing region of the dehumidifying rotor 10 is increased, whereby the amount of moisture absorbed by the dehumidifying rotor 10 is increased. As a result, the dehumidifying ability is improved. In addition, since the blown air volume is maximized, the clothes drying ability is improved by supplying a large amount of air to the clothes.

  Next, in the low temperature dehumidification mode in winter, the compressor 5, the air blowing means 9, and the driving means 15 are turned on, the heater 11A is also turned on, and the air volume adjusting means 13 is in the middle opening state. When the heater 11A is in the ON state and the air volume adjusting means 13 is in the middle opening state at a low temperature as described above, the air supplied from the radiator 6 to the moisture releasing portion 11 of the dehumidifying rotor 10 is heated, and further, the intake port 1A Thus, air that has not passed through the moisture release section 11 of the dehumidifying rotor 10 that has passed through the air volume adjusting means 13 is supplied at a medium air volume.

  That is, the reason why the medium amount of air that does not pass through the radiator 6 and the dehumidifying rotor 10 is supplied from the air inlet 1A to the heat absorber 8 is that the air passes through the heater 11A as compared with the case where air is not supplied from the air inlet 1A. As the air volume decreases and the temperature of the heater 11A rises, the amount of moisture released from the dehumidifying rotor 10 increases, and further, the amount of air passing through the moisture absorbing area of the dehumidifying rotor 10 increases, so that the amount of moisture absorbed by the dehumidifying rotor 10 increases. This is to increase the dehumidifying capacity as a result.

  In this case, since the heater 11A is ON, the moisture dehumidifying capacity of the dehumidifying rotor 10 is increased. Therefore, due to the balance of moisture absorption and desorption of the dehumidifying rotor 10, the supply of air from the intake port 1A is performed when the heater 11A is turned off. Compared to a large amount.

  In this mode, it is possible to obtain an optimal air volume balance in order to obtain the maximum capacity when the heater 11A is turned on.

  Next, in the cold wind mode in summer, the compressor 5, the air blowing means 9, and the drive means 15 are turned on, the heater 11A is turned off, and the air volume adjusting means 13 is turned on. In this way, when the heater 11A is in the OFF state and the air volume adjusting means 13 is in the large opening state at high temperatures, the air that has not passed through the dehumidifying section 11 of the dehumidifying rotor 10 that has passed through the air volume adjusting means 13 from the intake port 1A. Will be supplied with a large air volume.

  That is, in addition to turning off the heater 11A so that the air is not heated, the reason why a large amount of air that does not pass through the radiator 6 and the dehumidifying rotor 10 from the intake port 1A is supplied to the heat absorber 8 is as follows. This is to improve the cool air capacity by increasing the amount of heat absorption by maximizing the amount of air passing through the air, lowering the temperature of the air passing therethrough, and maximizing the amount of blown air.

  Next, at the extremely low temperature in winter (when the evaporating temperature sensor detects a predetermined temperature or lower), the operation is automatically performed in the defrosting mode. At this time, the compressor 5 is turned off, the air blowing means 9 is turned on, the driving means 15 is turned on, the heater 11A is also turned on, and the air volume adjusting means 13 is fully closed. That is, at the time of extremely low temperature, in addition to stopping the compressor 5, the air volume adjusting means 13 is fully closed so that the air from the intake port 1A is not supplied to the heat absorber 8. The reason for this is that only the high-temperature air heated by the heater 11A is supplied to the heat absorber 8 to quickly raise the temperature of the heat absorber 8 to dissolve the frost formation on the heat absorber 8 and the wind generated by the frost formation on the heat absorber 8 This is to prevent the blockage of the road. However, since dehumidification is not performed in the defrosting mode operation, after the operation in the defrosting mode for a predetermined time, the operation mode set before entering the defrosting mode operation is restored.

  In the present embodiment, the air volume adjusting means 13 is built in the main body case 3 because the air volume adjusting means 13 is rotationally driven and is not deformed or damaged by an external force. is there. The reason why the air passage from the air inlet 1 is arranged above the air passage from the air inlet 1A is that the main air passage, that is, the compressor 5, the radiator 6, the expansion means 7, the heat absorber 8, the air This is because the air passage provided with the means 9 and the dehumidifying rotor 10 is the main, so that the air passage resistance is reduced by bringing the main air passage close to the exhaust port 2.

  For the same reason, the intake port 1 is provided above the outer peripheral surface of the main body case 3, the intake port 1 </ b> A is provided below, and the exhaust port 2 is provided on the upper surface of the main body case 3.

  As described above, the present invention includes the main body case having the first and second intake ports and the exhaust port, and the heat pump provided in the main body case, as described above. It is formed by a compressor and a radiator, an expansion means, and a heat absorber sequentially provided downstream of the compressor, and the air sucked into the main body case from the first intake port is exhausted through the radiator and the heat absorber in this order. A first air passage that blows air to the mouth, 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, and the first and first The air supply means for supplying air to the second air supply passage is provided, and the moisture release portion of the dehumidification rotor is provided between the heat radiator and the heat absorber of the first air supply passage. Provided between the heat sink and the exhaust port of the second air passage, the first air passage A heater provided between the moisture releasing section of the dehumidifying rotor and reheater, said the second air passage having thereon a flowing amount adjusting means, in which it is possible to improve the dehumidification capacity.

  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 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 dehumidification rotor, it is provided between the exhaust ports. By heating the air that passes through the radiator, a large amount of moisture can be evaporated from the moisture release section, and then this large amount of moisture can be condensed by the heat absorber. Can do it.

  In addition, the air that has been condensed by the heat absorber will then reach the moisture absorption part of the dehumidification rotor. As described above, the moisture absorption part is heated by the heater in the moisture release part and becomes dry. Therefore, moisture contained therein can be sufficiently absorbed even in a low temperature state.

  And in addition to such a configuration, in the present invention, the first air passage that blows the air sucked into the main body case from the first air inlet to the exhaust port via the heat sink and the heat absorber, and Since the second air passage for blowing the air sucked into the main body case from the second air inlet to the exhaust port via the heat absorber is provided, and the air volume adjusting means is provided in the second air passage, In addition to the use of the first air passage, the second air passage can be used by adjusting the air passage, so that, for example, the optimum dehumidifying operation can be performed for each season of spring, summer, autumn and winter.

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