Dehumidification department.

In the above conventional example, the air is directly supplied to the radiator or the air having passed through the moisture absorbing portion of the dehumidification rotor is formed.

On the other hand, the air that has passed through the moisture absorbing portion causes a temperature rise due to the heat of adsorption of the dehumidifying rotor during moisture absorption or the heat remaining in the heating portion of the moisture releasing portion.

That is to say, in order to cool the radiator of the refrigerating cycle, it is possible to form air to be used at room temperature or air which is further raised in temperature from room temperature. In this case, it is difficult to enlarge the temperature difference between the radiator and the cooling air, so that the efficiency of forming the refrigeration cycle is lowered, and eventually the result of the reduction in the dehumidification efficiency is caused. When it is desired to maintain the dehumidification efficiency, in order to cool the necessary heat, it is necessary to increase the amount of air supplied to the radiator, and it is necessary to increase the size of the blower.

Further, the first air supply path that supplies air from the suction port to the moisture absorption unit and is discharged from the air outlet is provided, and the air is sucked from the suction port and supplied in the order of the heating unit, the moisture releasing unit, the heat absorber, and the radiator. The second air supply path that is discharged from the air outlet.

As described above, according to the present invention, the air is cooled by a different air supply path than the air supply path through which the temperature of the moisture absorbing portion of the dehumidifying rotor rises. Heater. With this configuration, it is possible to use a cooler air to cool the radiator, thereby improving the cooling efficiency of the refrigeration cycle and improving the dehumidification efficiency of the dehumidification device. Further, since the radiator can be cooled by the low-temperature air, the necessary amount of heat can be cooled by a small amount of air, and the amount of air can be reduced, thereby making it possible to miniaturize the blower. As a result, the size of the body can be made small, and the dehumidification efficiency can be improved.

The main body casing 1 is provided with a refrigeration cycle in which the compressor 4, the radiator 5, the expander 6, and the heat absorber 7 are sequentially connected in a ring shape to circulate the refrigerant, and the indoor air is blown from the suction port 2 toward the air outlet 3. The air supply unit 8. In addition, it also includes a moisture absorbing portion 9 that adsorbs moisture from the air and emits moisture. The dehumidification rotor 11 of the moisture releasing unit 10 of the air is provided with a heating unit 12 that heats the air supplied to the moisture releasing unit 10 and the moisture releasing unit 10.

Further, in the main body casing 1, the dehumidification rotor 11, the heat absorber 7, the radiator 5, and the air blowing portion 8 are arranged in this order from the suction port 2. The heat absorber 7 and the upper end of the heat sink 5 are arranged to have the same height. The dehumidification rotor 11 is formed in a disk shape and is erected so that the center shaft can be rotated in the horizontal direction and rotated by the driving portion 13. Further, a heating portion 12 is provided on the wind side of the dehumidifying portion 10 of the dehumidifying rotor 11. The dehumidifying portion 10 and the heat absorber 7 are disposed to face each other.

Further, in the main body casing 1, a funnel-shaped water collecting portion 14 is provided below the heat absorber 7, and the sump 15 is disposed detachably from the main body casing 1 below the water collecting portion 14.

That is, it is formed such that dew condensation is performed on the portion of the heat absorber 7, and the dew condensation water is collected in the funnel-shaped water collecting portion 14 to flow into the sump 15.

In the present embodiment, the first air supply path 16 that sucks air from the suction port 2 and supplies it to the moisture absorption unit 9, and discharges it to the air outlet 3 through the air supply unit 8 is provided, and air is taken from the suction port 2 The suction unit is supplied in the order of the heating unit 12, the moisture releasing unit 10, the heat absorber 7, and the radiator 5, and the second air blowing path 17 that is discharged from the air outlet through the air blowing unit 8.

Specifically, in the first air blowing path 16, the indoor air taken in 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 becomes dry air. In addition, due to the heat of adsorption when adsorbing moisture, indoor air will In a state where the humidity has decreased and the temperature has risen, it is mainly sucked by the air blowing portion 8 through the upper portion of the radiator 5 and the heat absorber 7, and is blown into the room from the air outlet 3.

On the other hand, in the second air blowing path 17, the indoor air heated by the heating unit 12 is supplied to the moisture releasing portion 10 of the dehumidifying rotor 11. In the moisture releasing unit 10, the moisture adsorbed by the moisture absorbing unit 9 is moved to the moisture releasing unit 10 by the rotational driving of the dehumidifying rotor 11, and is released into the air supplied by the heating of the heating unit 12. This high-humidity air is supplied to the heat absorber 7, and by dehumidifying the high-humidity air, water is formed into water droplets and taken out. Thereafter, the cooled air is supplied to the radiator 5 to cool the radiator 5. Then, the air that has taken up the heat from the radiator 5 and raises the temperature is attracted by the blower unit 8. The freezing cycle is such that the heat sink 5 is effectively cooled to increase the cooling efficiency when the heat sink 7 is cooled.

As described above, for the radiator 5 of the refrigeration cycle, air cooled to a temperature lower than room temperature by the heat absorber 7 is supplied, and is formed to rise in temperature with the moisture absorbing portion 9 passing through the dehumidification rotor 11. The air supply path has different air supply paths. With this configuration, the cooler 5 can be cooled by using the cooler air to improve the cooling efficiency of the refrigeration cycle, and the dehumidification efficiency of the dehumidifier can be improved. In addition, since the radiator can be cooled by the air at a low temperature, the amount of heat can be cooled by a small amount of air, and the amount of air can be reduced. Therefore, the size of the blower unit 8 can be reduced, the amount of power consumption can be reduced, and the noise can be reduced. feasible. As a result, the size of the body can be made small, and the dehumidification efficiency can be improved.

Further, in the present embodiment, it is characterized in that it is provided with the third The air supply path 18 is such that the air is sucked from the suction port 2 and supplied in the order of the heat absorber 7 and the heat sink 5, and is discharged from the air outlet 3 through the air blowing unit 8.

In other words, in the third air supply passage 18, the indoor air sucked from the suction port 2 is mainly supplied to the heat absorber 7 through the heating unit 12 and the lower portion of the dehumidification rotor 11, and is cooled to perform dew condensation. The water is taken out to form a water drop. After that, the cooled air is supplied to the radiator 5 to cool the radiator 5. Then, the air that has taken up the heat from the radiator 5 and raises the temperature is attracted by the blower unit 8.

Among the air volumes blown to the moisture releasing portion 10 of the dehumidifying rotor 11, there is an optimum air volume for forming the air at the outlet of the moisture releasing portion 10 to be more easily dew condensation air (high humidity and low temperature air). On the other hand, the cooling condensation in the heat absorber 7 also has an optimum air volume depending on the surface area, the operating heat of the refrigeration cycle, and the like. In order to solve the imbalance of the air volume, by providing the third air blowing unit described above, it is possible to balance the optimum air volume of the heat absorber 7 with the optimum air volume for the moisture releasing unit 10.

Further, between the moisture releasing portion 10 of the dehumidifying rotor 11 and the heat absorber 7, a communication air passage 21 that connects the second air blowing path 17 and the third air blowing path 18 may be provided. Specifically, the communication air passage 21 is a gap between the periphery of the moisture releasing portion 10 of the dehumidifying rotor 11 and the heat absorber 7 . In other words, a part of the indoor air flowing through the third air supply path 18 can also flow from the second air supply path 17 to the heat absorber 7 through the communication air passage 21.

In the second air blowing path 17, the air flowing out from the moisture releasing unit 10 contains a large amount of water, and the residual heat of the heating unit 12 is also added to change the temperature. It is high and makes the sensible heat ratio larger. However, as described above, the indoor air from the third air blowing path 18 is mixed into the air through the communication air passage 21 so that the air flowing from the moisture releasing portion 10 in the second air blowing path 17 toward the heat absorbing air 7 is made. The temperature drops, which reduces the sensible heat ratio and creates a more condensable air.

In this way, the imbalance of the air volume can be solved, and the air flowing up through the heat absorber 7 can be formed as air which is easy to dew, and the dehumidification efficiency of the dehumidifying device can be improved.

Further, in the present embodiment, the fourth air blowing path 19 is provided, and the fourth air blowing path 19 sucks air from the suction port 2 and supplies it to the radiator 5 to be discharged from the air outlet 3.

In other words, in the fourth air supply path 19, the indoor air taken in from the suction port 2 is mainly supplied to the radiator 5 through the heater 12, the dehumidification rotor 11 and the heat absorber 7, and the radiator 5 is cooled. After that, it is attracted to the blower unit 8.

The cooling condensation in the heat absorber 7 has the most appropriate air volume depending on the surface area or the operating heat of the refrigeration cycle. On the other hand, in the case of the refrigeration cycle, the heat sink 5 is effectively cooled, and the cooling efficiency is increased when the heat sink 7 is cooled. As described above, since the fourth air blowing path 19 can be disposed to supply a larger amount of air to the radiator 5, the cooling efficiency of the refrigeration cycle can be improved, and the dehumidifying efficiency of the dehumidifying device can be improved.

Further, in the present embodiment, the dehumidification rotor 11, the heat absorber 7, the radiator 5, and the blower portion 8 are arranged side by side in the horizontal direction from the suction port 2 side in the main body casing 1, and The heating portions 12 are arranged side by side The windward side of the moisture releasing portion 10.

In other words, the air supply opening of each element component can be disposed so as to face the air passage direction, and it is not necessary to make a space for the turning of the air passage, and the like, and the air blower having the miniaturization of the dehumidification device and the air blowing resistance is reduced.

Thereby, in the fifth air blowing path 20, the indoor air taken in 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 becomes dry air. Further, since the heat of adsorption at the time of adsorbing moisture is generated, the indoor air is in a state in which the humidity is lowered and the temperature is raised. Thereafter, it is supplied to the heat sink 5 through the upper portion of the heat absorber 7. Although air having a rising temperature is formed in the moisture absorbing portion 9, it is still lower in temperature than the temperature of the refrigerant of the radiator 5, so that it can be borrowed It is used for cooling of the heat sink 5 by being supplied to the heat sink 5. Even if the supply amount of the air to the radiator 5 is only slightly increased, the amount of heat radiation in the radiator 5 can be increased, and the cooling efficiency of the refrigeration cycle can be increased.

In this way, the dehumidification efficiency of the dehumidification device can be improved.

Further, in the present embodiment, the first air supply path 16 that sucks air from the suction port 2 and supplies it to the moisture absorption unit 9, and discharges the air to the air outlet 3 through the air supply unit 8 and air from the suction port 2 is included.
