(Embodiment)
In FIGS. 1 and 2, in the box-shaped main body case 1, the air outlet 3 is arranged on the upper part of the main body case 1, and the suction port 2 is arranged on the side surface. The suction port 2 includes a first suction port 2R and a second suction port 2L. The first suction port 2R is provided on the right side surface of the main body case 1, and the second suction port 2L is provided on the left side surface of the main body case 1.

In the main body case 1, a refrigerating cycle 8 is installed in which a compressor 4, a radiator 5, an expander 6, and a heat absorber 7 are sequentially connected in an annular shape to circulate a refrigerant, and indoor air is sucked from a suction port 2 to an outlet 3. A ventilation means 13 for blowing air is installed in the air. 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 air blowing means 13 are sequentially arranged in this order. The upper ends of the heat absorber 7 and the radiator 5 are arranged so as to be at the same height. 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 rotating portion 14. 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 16 is provided below the heat absorber 7, and a water collecting tank 17 is detachably attached to the main body case 1 below the water collecting means 16. 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 16 and flows into the water collecting tank 17.

The main body case 1 includes a first air passage 18, a second air passage 19, a third air passage 20, and a fourth air passage 21.

The first air passage 18 is an air passage that sucks air from the suction port 2, supplies it to the moisture absorbing portion 9, and discharges it to the air outlet 3 via the air blowing means 13. In the first air passage 18, 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 13 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.

The second air passage 19 sucks air from the suction port 2, 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 discharges the air from the air outlet 3 via the air passage 13. Is. In the second air passage 19, 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 13. In the refrigeration cycle 8, effective cooling of the radiator 5 increases the cooling efficiency when cooling the heat absorber 7.

The third air passage 20 is an air passage that sucks air from the suction port 2, supplies the air to the radiator 5, and discharges the air from the air outlet 3 via the air blowing means 13. In the third air passage 20, the indoor air sucked from the suction port 2 is supplied to the radiator 5 mainly through the heating means 12, the dehumidifying rotor 11, and the lower part of the heat absorber 7, and cools the radiator 5. After that, it will be sucked by the air blowing means 13.

For cooling dew condensation in the heat absorber 7, an optimum air volume exists depending on the surface area thereof, the operating heat amount of the refrigerating cycle 8, and the like. On the other hand, in the refrigerating cycle 8, effective cooling of the radiator 5 increases the cooling efficiency when cooling the heat absorber 7. By arranging the third air passage 20 as described above, a larger amount of air can be supplied to the radiator 5, so that the cooling efficiency of the refrigerating cycle 8 can be improved and the dehumidifying efficiency of the dehumidifying device is improved. It is something that can be made to do.

The fourth air passage 21 is an air passage that sucks air from the suction port 2, supplies the air in the order of the moisture release unit 10, the heat absorber 7, and the radiator 5, and discharges the air from the air outlet 3 via the air blowing means 13. In the fourth air passage 21, the indoor air sucked from the suction port 2 is supplied to the heat absorber 7 mainly through the lower part of the heating means 12 and the dehumidifying rotor 11, and is cooled to cause dew condensation. 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 13.

The air volume to be blown to the dehumidifying section 10 of the dehumidifying rotor 11 has an optimum air volume because the air at the outlet of the dehumidifying section 10 is air that is more likely to cause dew condensation (air with high humidity and low temperature). On the other hand, even for cooling dew condensation in the heat absorber 7, an optimum air volume exists depending on the surface area thereof, the operating heat amount of the refrigerating cycle 8, and the like. By providing the above-mentioned fourth air passage 21 in order to eliminate these imbalances in air volume, the optimum air volume to the endothermic absorber 7 and the optimum air volume to the moisture discharging portion 10 can be balanced.

A communication air passage 43 in which the second air passage 19 and the third air passage 20 communicate with each other may be provided between the dehumidifying portion 10 of the dehumidifying rotor 11 and the heat absorber 7. Specifically, the communication air passage 43 is a gap between the peripheral edge of the dehumidifying portion 10 of the dehumidifying rotor 11 and the heat absorber 7. That is, a part of the indoor air flowing through the fourth air passage 21 may flow from the second air passage 19 to the heat absorber 7 via the communication air passage 43.

In the second air passage 19, the air flowing out from the moisture discharging portion 10 contains a large amount of water, the residual heat of the heating means 12 is added, the temperature is high, and the ratio of sensible heat is large. As described above, by mixing the indoor air from the fourth air passage 21 with this air through the communication air passage 43, the temperature of the air flowing from the moisture discharging portion 10 in the second air passage 19 to the heat absorber 7 is increased. The air can be lowered, the sensible heat ratio can be lowered, and the air can be made more prone to dew condensation. In this way, the balance of the air volume of each acting air passage is determined by the ventilation resistance from the suction port 2 through each air passage to the air suction means 13.

FIG. 3 is a control block diagram in the present embodiment.

As shown in FIG. 3, the control unit 15 detects the temperature of the first temperature detection unit 22, the second temperature detection unit 24, and the third temperature detection unit 26. From the input, the control unit 15 can freely set the outputs of the compressor 4, the blower means 13, the heating means 12, and the rotating unit 14. Further, the first temperature fuse 23 is blown when the temperature exceeds the fourth temperature 30 and the second temperature fuse 25 exceeds the eighth temperature 36, and the current of the control unit 15 can be cut off.

As shown in FIG. 4, a first temperature detection unit 22 and a first temperature fuse 23 are attached to the heating means 12 in the second air passage 19. The detection unit of the first temperature detection unit 22 and the first temperature fuse 23 is located on a through hole provided in the sheet metal of the mounting surface in order to detect the temperature around the heating means 12 and the temperature around the main body cover. Have been placed. With this configuration, when an abnormality such as a decrease in the amount of air supplied to the heating means 12 such as blockage occurs, the first temperature detection unit 22 can detect an increase in the air temperature around the heating means 12. Further, the first temperature fuse 23 is arranged above the first temperature detection unit 22. With this configuration, when an abnormality occurs such as when a problem occurs in the blowing operation of the blowing means 13, the temperature tends to rise, so that the temperature rise inside the main body can be detected quickly, and the safety is further improved. be able to.

Hereinafter, FIGS. 5A, 5B, and 5C will be specifically described.

FIG. 5 shows a case where the laundry falls and blocks the suction port 2 and the air outlet 3, and the air volume is significantly reduced. In this case, the detection temperature 37 of the second temperature detection unit provided between the moisture release unit 10 and the heat absorber 7 in the second air passage 19 does not change much, but the first temperature provided in the heating means 12 The detection temperature 31 of the detection unit rises. The increase value of the detection temperature 31 of the first temperature detection unit is larger than the increase value of the detection temperature 37 of the second temperature detection unit.

As shown in FIG. 5A, when the detection temperature 31 of the first temperature detection unit becomes higher than the first temperature 27, the control unit 15 reduces the output of the heating means 12.

As a result, the temperature rise of the heating means 12 can be quickly detected, the temperature rise of the resin component can be prevented, and the safety can be further improved. Further, since the output of the heating means 12 is reduced, the heat remaining in the heating means 12 can be diffused, and the temperature inside the main body can be lowered. The operation of FIG. 5A is also effective when the power supply voltage input to the main body rises abnormally or when the suction port 2 and the outlet 3 are blocked by dust or dirt.

FIG. 5B shows a case where the laundry blocking the suction port 2 and the air outlet 3 is removed. That is, it is the case where the blowing means 13 is restored. As a result, the heat remaining in the heating means 12 is discharged, and as shown in FIG. 5B, when the detection temperature 31 of the first temperature detection unit becomes lower than the second temperature 28, the control unit 15 Can restore the heating amount of the heating means 12.

As a result, the function of the dehumidifying device can be returned to the maximum without any operation by the user, and the convenience can be improved. The operation of FIG. 5B is effective even when the abnormally increased power supply voltage is restored or when dust or dirt that has blocked the suction port 2 or the outlet 3 is removed.

As shown in FIG. 5C, when the detection temperature 31 of the first temperature detection unit becomes higher than the third temperature 29, the control unit 15 rotates the control unit 15 with the compressor 4 and the heating means 12. The unit 14 is stopped. As a result, the heat inside the main body can be discharged to the outside of the main body by the blowing means 13, and the temperature inside the main body can be lowered. As a result, safety can be further improved.

FIG. 6 shows a case where a problem occurs in the first temperature detection unit 22, and the first temperature detection unit 22 does not detect an increase in the air temperature around the heating means 12. As shown in FIG. 5, when the detection temperature 32 of the first temperature fuse becomes higher than the fourth temperature 30, the control unit 15 includes the compressor 4, the heating means 12, the blowing means 13, and the rotation. The moving part 14 and the moving part 14 can be stopped. Thereby, the safety can be further improved.

As shown in FIGS. 4 and 7, a second temperature detection unit 24 and a second temperature fuse 25 are attached between the moisture discharge unit 10 and the heat absorber 7 in the second air passage 19. The moisture releasing portion 10 and the heat absorber 7 face each other. With this configuration, when the heat of vaporization of the dehumidifying rotor 11 decreases when the humidity is low, the second temperature detection unit 24 detects an increase in the air temperature near the dehumidifying rotor 11, and the detection temperature becomes higher than the fifth temperature. The control unit 15 can reduce the output of the heating means 12. Further, the second temperature fuse 25 is arranged above the second temperature detection unit 24 and on the upstream side in the rotation direction of the dehumidifying rotor 11. With this configuration, when the humidity is low, the temperature rise is slower than that of the second temperature detection unit 24, so that the occurrence of premature blow of the second temperature fuse 25 can be reduced. Further, when an abnormality occurs such as when the rotation of the dehumidifying rotor 11 has a problem, the temperature tends to rise, so that the temperature rise in the main body can be detected quickly, and the safety can be further improved. ..

Hereinafter, FIGS. 8A, 8B, and 8C will be specifically described.

FIG. 8 shows a case where the heat of vaporization of the dehumidifying rotor 11 decreases and the air temperature in the vicinity of the dehumidifying rotor 11 rises when the humidity is low. In this case, the detection temperature 31 of the first temperature detection unit provided in the heating means 12 does not change much, but the detection temperature 37 of the second temperature detection unit rises. The increase value of the detection temperature 37 of the second temperature detection unit is larger than the increase value of the detection temperature 31 of the first temperature detection unit.

As shown in FIG. 8A, when the detection temperature 37 of the second temperature detection unit becomes higher than the fifth temperature 33, the control unit 15 reduces the output of the heating means 12.

This makes it possible to prevent deterioration of the dehumidifying rotor 11 and deterioration of resin parts, and further improve safety. Further, since the output of the heating means 12 is reduced, the heat remaining in the heating means 12 can be diffused, and the temperature inside the main body can be lowered.

FIG. 8B shows a case where the humidity in the room rises from the low humidity state due to the inflow of high humidity outside air or the drying of laundry. As shown in FIG. 8B, when the detection temperature 37 of the second temperature detection unit becomes lower than the sixth temperature 34, the control unit 15 can restore the heating amount of the heating means 12.

As a result, the function of the dehumidifying device can be returned to the maximum without any operation by the user, and the convenience can be improved.

As shown in FIG. 8C, when the detection temperature 37 of the second temperature detection unit becomes higher than the seventh temperature 35, the control unit 15 rotates the control unit 15 with the compressor 4 and the heating means 12. The unit 14 is stopped. As a result, the heat inside the main body can be discharged to the outside of the main body by the blowing means 13, and the temperature inside the main body can be lowered. As a result, safety can be further improved.

FIG. 9 shows a case where a malfunction occurs in the operation of the rotating portion 14, a malfunction occurs in the second temperature detection unit 24, and the second temperature detection unit 24 cannot detect the temperature rise of the dehumidifying rotor 11. As shown in FIG. 9, when the detection temperature 38 of the second temperature fuse becomes higher than the eighth temperature 36, the control unit 15 includes the compressor 4, the heating means 12, the blowing means 13, and the rotation. The moving part 14 and the moving part 14 can be stopped. As a result, deterioration of the dehumidifying rotor 11 can be prevented and safety can be further improved.

As shown in FIG. 4, a third temperature detection unit 26 is attached between the moisture absorbing unit 9 and the air blowing means 13 in the first air passage, and is arranged on the upstream side in the rotation direction of the dehumidifying rotor 11. Specifically, the third temperature detection unit 26 faces the moisture absorbing portion 9 in the rotation axis direction of the dehumidifying rotor 11, and is installed between the heat absorber 7 and the moisture absorbing portion 9 when viewed from above. ..
With this configuration, when frost is generated in the heat absorber 7 at low temperature and low humidity and the second air passage is blocked, the third temperature detection unit 26 raises the air temperature between the moisture absorption unit 9 and the air blower means 13. When the detection temperature becomes higher than the ninth temperature, the control unit 15 can reduce the output of the heating means 12.

Hereinafter, FIGS. 10A, 10B, and 10C will be specifically described.

FIG. 10 shows a case where frost is generated in the endothermic device 7 at low temperature and low humidity, and the second air passage is blocked. In this case, the detection temperature 37 of the second temperature detection unit provided between the moisture release unit 10 and the heat absorber 7 in the second air passage 19 and the detection temperature of the first temperature detection unit provided in the heating means 12. The temperature of 31 does not rise so much, but the detection temperature 42 of the third temperature detection unit attached between the moisture absorbing unit 9 and the air blowing means 13 in the first air passage increases. The increase value of the detection temperature 42 of the third temperature detection unit is larger than the increase value of the detection temperature 31 of the first temperature detection unit and the increase value of the detection temperature 37 of the second temperature detection unit.

As shown in FIG. 10A, when the detection temperature 42 of the third temperature detection unit becomes higher than the ninth temperature 39, the control unit 15 reduces the output of the heating means 12.

This makes it possible to prevent deterioration of the resin parts and further improve safety. Further, since the output of the heating means 12 is reduced, the heat remaining in the heating means 12 can be diffused, and the temperature inside the main body can be lowered.

FIG. 10B shows a case where an abnormal time such as an inflow of high-humidity outside air or a rise in room temperature is resolved. As shown in FIG. 10B, when the detection temperature 42 of the third temperature detection unit becomes lower than the tenth temperature 40, the control unit 15 can restore the heating amount of the heating means 12.

As a result, the function of the dehumidifying device can be returned to the maximum without any operation by the user, and the convenience can be improved.

As shown in FIG. 10 (c), when the detection temperature 42 of the third temperature detection unit becomes higher than the eleventh temperature 41, the control unit 15 rotates the control unit 15 with the compressor 4 and the heating means 12. The unit 14 is stopped. As a result, the heat inside the main body can be discharged to the outside of the main body by the blowing means 13, and the temperature inside the main body can be lowered. As a result, safety can be further improved.

The dehumidifying device according to the present invention can promptly detect the occurrence of an abnormality at the time of blockage, low temperature, low humidity, etc., and further improve the safety, and is used for air conditioning equipment and the like using heat generating means. It is useful.
