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

  That is, in the conventional dehumidifying device, the indoor air is condensed by the heat absorber, and thereby dehumidification is performed. However, the indoor air is supplied to the heat absorber as it is. There was a limit to improving the dehumidifying ability because the air could not be easily condensed (increased moisture content, increased relative humidity). 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.

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

  FIG. 1 is a simplified diagram for easy understanding of the configuration and operation of an embodiment of the present invention. First, the overall configuration and operation will be described with reference to FIG.

  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. Between the air outlet 6 and the exhaust port 2, the heater 11 </ b> A interposed between the heat radiator 6 of this air passage and the moisture releasing portion 11 of the dehumidifying rotor 10, and the intake port 1 to the heat absorber 8. This is because the air volume adjusting means 13 is interposed in the second air passage 17.

  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 heat absorber 8 and then to the compressor 5. 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 16 that blows the air taken into the main body case 3 from the air inlet 1 to the air outlet 2 through the heat radiator 6 and the heat absorber 8 sequentially, A second air passage 17 is provided for blowing air sucked into the main body case 3 from the air inlet 1 to the air outlet 2 via the heat absorber 8, and an air volume adjusting means 13 is interposed in the second air passage 17. I am letting.

  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, the air volume adjusting means 13 is a rectangular plate 13a that is long in the vertical direction as shown in FIG. 3, and this rectangular plate 13a is rotationally driven. Therefore, by rotating the rectangular plate 13a, the angle of the rectangular plate 13a is changed. The opening area of the second air passage 17 from the air inlet 1 to the heat absorber 8 can be changed. Depending on the angle of the rectangular plate 13a, the second air passage 17 from the air inlet 1 to the heat absorber 8 can be switched to a small opening, a middle opening, a fully open state, or a fully closed state.

  First, in this rated dehumidification mode, a small opening state is set. As a result, in the heat absorber 8, the air that has passed through the moisture release portion 11 of the dehumidification rotor 10 described above from the air inlet 1 through the first air passage 16, and the air from the air inlet 1 through the second air passage 17. Thus, 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 is 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 1 through the second air passage 17 in this way is as follows. This is because the amount of air passing through the moisture absorption region of the dehumidification rotor 10 is increased as compared with the case where air is not supplied via the, thereby increasing the moisture absorption amount of the dehumidification rotor 10 and improving the dehumidification capability.

  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 1 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 fully opened. In this way, when it is desired to quickly dry the clothing, if the heater 11A is turned on and the air volume adjusting means 13 is fully opened, the air supplied from the radiator 6 to the moisture releasing portion 11 of the dehumidifying rotor 10 is heated and further sucked. Air that has not passed through the moisture release section 11 of the dehumidification rotor 10 that has passed through the air volume adjusting means 13 from the mouth 1 through the second air passage 17 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 from the intake port 1 through the second air passage 17 is supplied to the heat absorber 8 is as follows. The amount of air passing through the heater 11A is decreased and the temperature of the heater 11A is increased as compared with the case where no air is supplied via the heater, thereby increasing the amount of moisture released from the dehumidifying rotor 10, and further, the moisture absorption of the dehumidifying rotor 10 This is because the amount of moisture absorbed by the dehumidifying rotor 10 is increased by increasing the amount of air passing through the region, and as a result, the dehumidifying capacity 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. As described above, when the heater 11A is in the ON state and the air volume adjusting means 13 is in the middle opening state at the low temperature, 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 1 Thus, 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 through the second air passage 17 is supplied at a medium air volume.

  That is, the reason why a medium amount of air that does not pass through the radiator 6 and the dehumidifying rotor 10 from the intake port 1 through the second air passage 17 is supplied to the heat absorber 8 is as follows. The amount of air passing through the heater 11A is decreased and the temperature of the heater 11A is increased by increasing the temperature of the heater 11A as compared with the case where no air is supplied via the motor 17, thereby further increasing the amount of moisture released from the dehumidifying rotor 10. This is because the amount of moisture absorbed by the dehumidifying rotor 10 is increased by increasing the amount of air passing through the moisture absorption region, and as a result, the dehumidifying capacity is improved.

  In this case, since the heater 11A is ON, the moisture dehumidifying capacity of the dehumidifying rotor 10 increases. Therefore, due to the balance of moisture absorption and desorption of the dehumidifying rotor 10, the supply of air from the intake port 1 is performed when the heater 11A is turned OFF. Compared to a large amount. In this mode, an optimal air volume balance can be obtained 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 driving means 15 are turned on, the heater 11A is turned off, and the air volume adjusting means 13 is fully opened. Thus, at high temperatures, the heater 11A is turned off and the air volume adjusting means 13 is fully opened, so that the dehumidification rotor 10 that has passed through the air volume adjusting means 13 from the intake port 1 through the second air passage 17 is released. Air that has not passed through the wet section 11 is supplied with a large air volume.

  That is, in addition to turning off the heater 11A so that the air is not heated, air that does not pass through the radiator 6 and the dehumidifying rotor 10 from the air inlet 1 through the second air passage 17 to the heat absorber 8 in this way. The reason for supplying a large amount is to improve the cold air capacity by increasing the heat absorption amount by maximizing the amount of air passing through the heat absorber 8, lowering the temperature of the passing air, and maximizing the blowout air amount.

  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, and no air is supplied from the intake port 1 to the heat absorber 8 through the second air passage 17. 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. .

  Now that the basic configuration and operation have been understood, the specific configuration will be described with reference to FIGS.

5 to 7, the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals.
The main body case 3 described with reference to FIGS. 1 to 3 has a substantially rectangular parallelepiped shape, as can be understood from FIGS. 5 to 7. The exhaust port 2 is provided on the upper surface side as shown in FIG.

  In addition, as can be understood from FIGS. 5 and 6, the air volume adjusting means 13 is arranged by arranging the rectangular plates 13 a shown in FIG. 3 on the right side when viewed from the front in the main body case 3. It is configured.

  Further, the rotating shaft 13b is connected to the upper side and the lower side of the rectangular plate 13a. That is, by rotating the rotating shaft 13b, the angle of the rectangular plate 13a connected to the rotating shaft 13b changes, so that the opening area of the second air passage 17 from the inlet 1 to the heat absorber 8 can be changed. . That is, by the air volume adjusting means 13 constituted by the rectangular plate 13a, as described in FIGS. 1 to 3 described above, the second air passage 17 extending from the air inlet 1 to the heat absorber 8 is made small, middle, fully open, It can be switched to the fully closed state, and as a result, the optimum dehumidifying operation can be performed for each season of spring, summer, autumn and winter.

  Next, the air intake 1 shown in FIGS. 1 to 3 is provided as shown in FIG. 7 on the back side of the main body case 3 as described above, and this air intake 1 has a rectangular shape. As shown in FIG. 7, a plurality of crosspieces 1 a are provided on the inner side with a predetermined interval left and right and up and down.

  Of the plurality of crosspieces 1a, the left side of the crosspiece 1a provided in the vertical direction is the operation confirmation window 1A of the air volume adjusting means 13 from the left side as viewed from the rear. That is, it is possible to confirm the operation of the air volume adjusting means 13 provided in the main body case 3, specifically the rectangular plate 13a, through the operation confirmation window 1A.

  In order to facilitate such an operation check, the air volume adjusting means 13 provided in the main body case 3, specifically, the rectangular plate 13 a is white, so that the inside of the dark main body case 3 Even with the rectangular plate 13a arranged in the above, the operation can be easily confirmed from the operation confirmation window 1A provided on the left side of the intake port 1.

  In this embodiment, the operation check window 1A is configured on the left side of the two bars 1a from the left shown in FIG. 7, and as a result, the operation check window 1A is the leftmost bar 1a. It has a state with openings on both sides. Here, when performing the air flow control, when the rectangular plate 13a of the air flow adjusting means 13 is fully closed, the rectangular plate 13a does not exist at all in the two openings on both sides of the leftmost rail 1a. In other words, the state cannot be confirmed at all.

  Further, when performing the air volume control, when the rectangular plate 13a of the air volume adjusting means 13 is in a small opening state, the rectangular plate 13a from the right side in FIG. 7 of the two openings present on both sides of the leftmost rail 1a. Can be confirmed.

  Furthermore, when performing the air volume control, when the rectangular plate 13a of the air volume adjusting means 13 is in a fully open state, a rectangular shape is formed from the right and left sides of FIG. 7 out of the two openings existing on both sides of the leftmost rail 1a. It will be in the state which can confirm the board 13a.

  Further, when performing the air flow control, when the rectangular plate 13a of the air flow adjusting means 13 is in the middle opening state, it exists on both sides of the leftmost rail 1a in the state between the small opening state and the full opening state. The rectangular plate 13a can be confirmed from the two openings.

  For this reason, it can confirm more reliably that the rectangular board 13a of the air volume adjusting means 13 will be in each state of a small opening, a middle opening, a full opening, and a full closing.

  Further, as is clear from FIG. 5, the case 9a constituting the air blowing means 9 has a circular arc shape on both the left and right sides, and the most important one is the right circular arc portion shown in FIG. Although not expressed in FIG. 7, the upper and lower intermediate portions of the arc-shaped portion protrude into the operation check window 1A so that the distance between the main body case 3 and the case 9a is as small as possible. 3 is made compact.

  However, even if the case 9a of the air blowing means 9 is projected into the operation check window 1A in this way, the case 9a has an arc shape as described above, and therefore the upper and lower portions thereof are not present in the operation check window 1A. The operation of the rectangular plate 13a described above can be sufficiently confirmed through the operation check window 1A in the portion where the case 9a does not exist.

  Accordingly, the operation of the rectangular plate 13a constituting the air volume adjusting means 13 can be reliably confirmed from the operation confirmation window 1A while maintaining the compact shape of the main body case 3. Then, as shown in FIGS. 6 and 7 from the state shown in FIG. 5 to the state shown in FIGS. 6 and 7, the operation of the rectangular plate 13a constituting the air volume adjusting means 13 can be easily and reliably performed after the completed state. Therefore, it becomes extremely productive.

  FIG. 4 shows another embodiment of the present invention, in which a rotating shaft 13b is connected to one end side of the upper side and the lower side of the rectangular plate 13a. Thus, the rotating shaft 13b is connected to one end side. If connected, the area of the rectangular plate 13a that can be confirmed from the operation confirmation window 1A increases, and it becomes easier to confirm the operation.
