Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a box-shaped main body case, a suction port 2 is arranged on the side surface of the main body case 1, and an outlet 3 is arranged on the upper portion.

In the main body case 1, a refrigerating cycle is installed in which the compressor 4, the radiator 5, the expander 6, and the endothermic 7 are sequentially connected in an annular shape to circulate the refrigerant, and the indoor air is sent from the suction port 2 to the outlet 3. A blowing means 8 for blowing air is installed. Further, a dehumidifying rotor 11 having a moisture absorbing portion 9 that adsorbs moisture from the air and a moisture releasing portion 10 that releases moisture to the air is provided, and the air supplied to the moisture releasing portion 10 and the heating that heats the moisture releasing portion 10 are heated. The means 12 is provided.

Then, in the main body case 1, the dehumidifying rotor 11, the heat absorber 7, the radiator 5, and the blower means 8 are arranged in this order from the suction port 2. The dehumidifying rotor 11 is formed in a disk shape and is rotatably erected so that the central axis is in the horizontal direction, and is rotated by the driving means 13. Further, a heating means 12 is installed on the windward side of the dehumidifying portion 10 of the dehumidifying rotor 11. The moisture releasing portion 10 and the heat absorber 7 are arranged so as to face each other.

Further, in the main body case 1, a funnel-shaped water collecting means 14 is provided below the heat absorber 7, and a water collecting tank 15 is detachably attached to the main body case 1 below the water collecting means 14. It is placed in.

That is, dew condensation is caused by the heat absorber 7 portion, and the dew condensation water is collected by the funnel-shaped water collecting means 14 and flows into the water collecting tank 15.

Further, the main body case 1 includes a first air passage 16, a second air passage 17, and a third air passage 18. The first air passage 16 is an air passage that sucks air from the suction port 2 by the air blowing means 8, supplies the air to the moisture absorbing portion 9, and discharges the air to the air outlet 3 through the air blowing means 8. The second air passage 17 sucks air from the suction port 2 by the air blowing means 8 and supplies the air in the order of the heating means 12, the moisture release unit 10, the heat absorber 7, and the radiator 5, and from the air outlet via the air blowing means 8. It is an air passage that discharges.

The blowing means 8 has a scroll-shaped casing 8a, a fan motor 8b fixed to the casing 8a, and blades 8c rotated by the fan motor 8b.

More specifically, in the first air passage 16, the indoor air sucked from the suction port 2 is supplied to the moisture absorbing portion 9 of the dehumidifying rotor 11. At this time, the moisture in the air is adsorbed by the moisture absorbing portion 9, and the air becomes dry. Further, since the heat of adsorption is generated when the moisture is adsorbed, the indoor air is sucked by the blower means 8 mainly through the upper part of the radiator 5 and the heat absorber 7 in a state where the humidity is reduced and the temperature is raised. , The air will be blown into the room from the air outlet 3.

On the other hand, in the second air passage 17, the indoor air warmed by the heating means 12 is supplied to the dehumidifying section 10 of the dehumidifying rotor 11. In the moisture-releasing section 10, the moisture adsorbed by the moisture-absorbing section 9 moves to the moisture-releasing section 10 by the rotational drive of the dehumidifying rotor 11 and is discharged to the air supplied by the heating of the heating means 12. This high-humidity air is supplied to the endothermic device 7 and cooled to cause dew condensation, and moisture is taken out as water droplets. After that, the cooled air is supplied to the radiator 5 to cool the radiator 5. Then, heat is taken from the radiator 5, and the air whose temperature has risen is sucked into the blowing means 8. In the refrigeration cycle, effective cooling of the radiator 5 increases the cooling efficiency when cooling the heat absorber 7.

Further, in the third air passage 18, air is sucked from the suction port 2, supplied in the order of the heat absorber 7 and the radiator 5, and discharged from the air outlet 3 via the air blowing means 8. That is, in the third air passage 18, the indoor air sucked from the suction port 2 is supplied to the heat absorber 7 and cooled to cause dew condensation, and the moisture is taken out as water droplets. After that, the cooled air is supplied to the radiator 5 to cool the radiator 5. Then, heat is taken from the radiator 5, and the air whose temperature has risen is sucked into the blowing means 8.

A feature of the present embodiment is that the first air passage 16 is provided with an air volume adjusting means 19 for adjusting the air volume. The air flowing through the first air passage 16 passes through the moisture absorbing portion 9 of the dehumidifying rotor 11, and the air flowing through the second air passage 17 passes through the dehumidifying portion 10 of the dehumidifying rotor 11. In this way, since the suction and discharge are repeated through the same dehumidifying rotor 11, there is an optimum air volume balance, and the dehumidifying capacity is adjusted by adjusting the air volume of the first air passage 16 to the optimum air volume by the air volume adjusting member. Can be improved.

The air volume adjusting means 19 is arranged between the moisture absorbing portion 9 of the first air passage 16 and the air blowing means 8. Since the dehumidifying rotor 11 is rotatably supported, of the first air passage 16 and the second air passage 17, the air passages before and after the dehumidifying rotor 11 have a slight gap with the dehumidifying rotor 11 and communicate with each other. is doing. Specifically, the heating means 12 is arranged on the windward side of the moisture discharging portion 10, but there is a slight gap between the heating means 12 and the dehumidifying rotor 11. Further, on the leeward side of the moisture discharging portion 10, there is a casing 8a formed mainly of resin or the like, which forms a second air passage, and there is a slight gap between the dehumidifying rotor 11 and the casing 8a. .. Through this gap, in the air passages before and after the dehumidifying portion 10 of the dehumidifying rotor 11, the second air passage 17 passing through the dehumidifying portion 10 and the first air passage 16 passing around the dehumidifying portion 10 communicate with each other. is doing. Therefore, rather than providing the air volume adjusting means 19 between the suction port 2 and the moisture absorbing portion 9 of the dehumidifying rotor 11, the person providing the air volume adjusting means 19 between the moisture absorbing portion 9 of the dehumidifying rotor 11 and the blowing means 8 However, a part of the air flowing through the second air passage 17 can be suppressed from flowing into the first air passage 16 through this gap, and the dehumidifying capacity can be improved.

The air volume adjusting means 19 has a communication opening 20 through which the first air passage 16 passes, and an air volume adjusting member 21 that opens and closes the communication opening 20. The main body case 1 has a rotor support portion 22 that rotatably supports the dehumidifying rotor 11. The upper part of the rotor support portion 22 has a communication opening 20 and an air volume adjusting member 21.

The communication opening 20 has a horizontally long tubular shape and is an air passage that opens in the horizontal direction and communicates the moisture absorbing portion 9 of the dehumidifying rotor 11 and the blowing means 8. The first air passage 16 passes through the communication opening 20, and the air volume adjusting member 21 opens and closes the communication opening 20, that is, the first air passage 16.

As described above, by providing the communication opening 20 and the air volume adjusting member 21 in the rotor support portion 22, it is not necessary to provide a new support member for supporting the air volume adjusting member 21, and the number of parts can be reduced.

The air volume adjusting member 21 has a damper portion 23, a shaft portion 24, a support portion 25, and a motor portion (not shown).

The damper portion 23 has a horizontally long flat plate shape and is a component that closes the communication opening 20. The damper portion 23 is arranged in a horizontally long tubular communication opening 20.

The shaft portion 24 has a cylindrical shape and extends perpendicularly and horizontally to the axial direction of the communication opening 20. That is, it extends horizontally from both short sides of the damper portion 23 to the outside.

The support portion 25 is provided with a rotor support portion 22, and is a pair of holes that rotatably support the shaft portion 24. It is arranged on both side surfaces of the horizontally long tubular communication opening 20. When a pair of shaft portions 24 are inserted into these holes, the damper portion 23 becomes rotatable in the vertical direction.

The motor portion (not shown) rotates the damper portion 23 via the one-side shaft portion 24. The motor portion is arranged outside the horizontally long tubular communication opening 20.

In the above configuration, the operation of the air volume adjusting member 21 will be described. When the communication opening 20 is opened, the damper portion 23 is rotated by the motor portion, and the surface of the damper portion 23 is in a state of being substantially parallel to the axial direction of the communication opening 20. When the communication opening 20 is closed, the damper portion 23 is rotated by the motor portion, and the end portion of the damper portion 23 hits the inner surface of the communication opening 20 and is in an inclined state with respect to the axial direction of the communication opening 20. Further, it is also possible to hold the damper portion 23 in a state where the damper portion 23 is rotated by the motor portion and the communication opening 20 is opened and the communication opening 20 is closed.

By rotating the damper portion 23 in this way, the air volume of the first air passage 16 can be freely adjusted.

Further, the shaft portion 24 is arranged on the air blowing means 8 side of the damper portion 23. Specifically, when the damper portion 23 is rotated by the motor portion and the communication opening 20 is opened, the surface of the damper portion 23 becomes substantially parallel to the axial direction of the communication opening 20. When the damper portion 23 is viewed from above in this open state, the distance between the upstream end portion 23a and the shaft portion 24 in the ventilation direction of the damper portion 23 is the downstream end portion 23b and the shaft portion in the ventilation direction of the damper portion 23. Longer than the distance to 24. As described above, the shaft portion 24 is arranged on the downstream side in the blowing direction of both short sides of the damper portion 23.

As a result, when the communication opening 20 is closed by the damper portion 23, the damper portion 23 is rotated by the motor portion, and the upstream end portion 23a of the damper portion 23 in the blowing direction hits the inner surface of the communication opening 20 and the communication opening is opened. It is in an inclined state with respect to the axial direction of 20. In this state, when the air is blown by the blower means 8, the distance between the upstream end 23a and the shaft portion 24 in the blow direction of the damper portion 23 is the downstream end 23b and the shaft portion 24 in the blow direction of the damper portion 23. Since it is longer than the distance from the damper portion 23, a force acts on the damper portion 23 in a direction in which the damper portion 23 is more closed, and it is possible to prevent the generation of chattering noise.

Further, the support portion 25 is arranged on the lower side of the communication opening 20. If the damper portion 23 is held in the closed state, air is not supplied to the moisture absorbing portion 9, and the heating means 12 operates, the temperature of the dehumidifying portion 10 of the dehumidifying rotor 11 and the resin around it may rise excessively. There is. By arranging the support portion 25 on the lower side of the communication opening 20, in the unlikely event that the motor portion that rotates the damper portion 23 fails, the damper portion 23 moves in the opening direction by its own weight. As a result, it can be operated in a safe direction.

Further, the air volume adjusting member 21 is arranged above the heat absorber 7 or the radiator 5. As a result, the air volume adjusting member 21 can be installed in the space above the heat absorber 7 or the radiator 5, so that the main body case 1 can be miniaturized. Further, the configuration of the air volume adjusting member 21 will be specifically described. Among the communication openings 20, the opening height of the upper part of the heat absorber is made higher than the opening height of the upper part of the radiator 5, and the air volume adjusting member 21 is the heat absorber 7. Installed on top of. As a result, the damper portion 23 can be accommodated in the step between the upper air passage of the heat absorber 7 and the upper air passage of the radiator 5. That is, it is possible to minimize the pressure loss of the damper portion 23 of the first air passage 16.

Further, the lower end of the heat absorber 7 is arranged at substantially the same height as the lower end of the radiator 5.

In this type of refrigeration cycle, the height (number of stages) of the radiator 5 is often larger than that of the endothermic 7 in order to optimize the balance between absorption and heat dissipation. The lower end of the radiator 5 is arranged at substantially the same height as the lower end of the heat absorber 7, and the upper end of the radiator 5 is arranged above the upper end of the heat absorber 7, so that the radiator is more than the heat sink 7. The height (number of stages) of 5 can be increased, and when the rotor support portion 22 also serves as the second air passage 17 and the third air passage 18, the damper portion 23 is provided at the step portion between the heat absorber 7 and the radiator 5. Since it can be installed, volumetric efficiency can be maximized.

The dehumidifying device according to the present invention can exhibit performance according to the purpose of the user, and is useful as a dehumidifying device used for a living space or the like.
