[0034] The technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.

[0035] The present application provides a rotary dehumidifier 100.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 In an embodiment of the present application, the rotary dehumidifier 100 is formed with a treatment air duct 101 for adjusting air humidity, the treatment air duct 101 is provided with a front surface cooling device 120 and a rotary wheel 130 in sequence according to the flow direction of fresh air, the rotary wheel 130 provides air power and moisture absorption for the treatment air duct 101.

[0037] The front surface cooling device 120 includes a cooling coil 121, a water collecting tank 122 and a water pump 123; the cooling coil 121 is used for cooling and dehumidifying fresh air; the water collecting tank 122 is used for collecting condensate water condensed on the surface of the cooling coil 121; the water pump 123 is arranged in the water collecting tank 122 and is used for discharging the condensate water in the water collecting tank 122 to the outside.

[0038] It can be understood that the rotary dehumidifier 100 of the technical scheme of the utility model solves the problem of difficult condensate water discharge in the prior art by integrating the cooling coil 121, the water collecting tank 122 and the water pump 123 in the front surface cooling device 120. Since the water collecting tank 122 can collect condensate water and discharge it to the outdoor through the water pump 123, it is not necessary to rely on gravity drainage, thereby avoiding the need to open a floor drain, dig a water collecting pit and other modifications to the installation environment, so that the equipment can be conveniently used on the first floor or floors where a floor hole cannot be opened for drainage, greatly reducing the installation and maintenance costs.

[0039] Specifically, the process air duct 101 is sequentially provided with the front surface cooling device 120 and the rotary wheel 130 in the direction of the fresh air flow, specifically: the air first passes through the cooling coil 121 in the front surface cooling device 120, so that the moisture in the air is condensed and the condensate water drops into the water collecting tank 122. The water pump 123 can discharge the condensate water to the outdoor through a pipeline. Such a connection can be connected to the water collecting tank 122 through a hose or can be directly installed inside the water collecting tank 122, so that the water pump 123 can smoothly extract and discharge the condensate water. The rotary wheel 130 is arranged behind the front surface cooling device 120, so that the air can be further dehumidified when entering the rotary wheel 130. Specifically, the rotary wheel 130 not only has a dehumidifying effect, but also can push the air flow.

[0040] Preferably, to reduce the space occupation, the water pump 123 is arranged inside the water collecting tank 122, and the water pump 123 is a submersible pump 123.

[0041] Please continue to refer to Figure 2 and Figure 3 In the specific embodiment of the utility model, the water collecting tank 122 is provided with a liquid level switch signal connected with the water pump 123, and the liquid level switch is formed with a first monitoring point 124a and a second monitoring point 124b.

[0042] The first monitoring point 124a is higher than the second monitoring point 124b, and the first monitoring point 124a is used to control the start of the water pump 123, and the second monitoring point 124b is used to control the stop of the water pump 123.

[0043] Specifically, when the condensate water level in the water collecting tank 122 reaches the height of the first monitoring point 124a, the liquid level switch sends a signal to the water pump 123, indicating that the water pump 123 starts to discharge the condensate water; when the condensate water level drops to the height of the second monitoring point 124b, the liquid level switch sends a signal to the water pump 123, indicating that the water pump 123 stops working. In this way, through the monitoring and control of the liquid level switch, the water pump 123 can be automatically started and stopped without manual intervention, so that the condensate water cannot overflow or accumulate too much.

[0044] And, the first monitoring point 124a is mainly arranged to ensure that the water pump 123 is started only when the condensed water reaches a certain height, so as to avoid energy waste and equipment wear caused by frequent starting. The second monitoring point 124b is mainly arranged to control the shutdown of the water pump 123, so as to prevent the water pump 123 from idling and prolong the service life of the water pump 123.

[0045] It can be understood that, in the embodiment, the combination of the liquid level switch and the water pump 123 improves the automation degree and use convenience of the rotary dehumidifier 100.

[0046] Further, on the basis of the above embodiment, the water pump 123 is arranged as a submersible pump 123, which can further avoid that the condensed water is stored too much in the water collecting tank 122, thereby reducing the influence on the indoor dehumidification effect.

[0047] In an embodiment, the water collecting tank 122 is formed with an opening, and the opening is provided with a fence type mounting table 125. The cooling coil 121 is arranged to face the wind and fixed to the fence type mounting table 125.

[0048] Specifically, the fence type mounting table 125 is designed to enable the condensed water to smoothly drip into the water collecting tank 122 through the opening of the mounting table, and the condensed water cannot accumulate on the fence type mounting table 125, thereby avoiding the retention of the condensed water around the cooling coil 121. The cooling coil 121 is arranged to face the wind, which mainly means that the cooling coil 121 is installed on the path of air flow, so as to maximize the contact area of air and the cooling coil 121 and enhance the cooling and dehumidification effect.

[0049] Please refer to Figure 1 and Figure 2 In an embodiment, the front surface cooling device 120 further comprises a filter 126, which is used to reduce the excessive pollution of impurities in the air to the cooling coil 121.

[0050] It can be understood that the filter 126 is used to reduce the particulate matters such as impurities and dust in the air into the cooling coil 121, so as to ensure the dehumidification efficiency of the cooling coil 121. Specifically, the filter 126 can be replaced to ensure the long-term stable operation of the cooling coil 121.

[0051] Further, the front surface cooling device 120 further comprises a heat exchange fin, which is arranged between the filter 126 and the cooling coil 121 and fixedly connected with the cooling coil 121, and is used to preliminarily reduce the heat in the air.

[0052] It can be understood that the design of the heat exchange fins is mainly used for increasing the heat exchange surface area, improving the heat exchange efficiency, increasing the heat exchange area between the cooling coil 121 and the air, thereby improving the air cooling and dehumidification effect.

[0053] Please refer to Figure 1 and Figure 4 In an embodiment of the present application, the rotary dehumidifier 100 is further provided with a regenerative air duct 102; the regenerative air duct 102 is sequentially provided with a condenser 140, the rotary wheel 130 and a regenerative air fan 150 according to the flow direction of the fresh air.

[0054] The condenser 140 and the cooling coil 121 constitute a common liquid cooling heat exchange system.

[0055] It should be noted that the purpose of the regenerative air duct is to remove the moisture adsorbed on the rotary wheel 130, so as to restore the moisture adsorption function of the rotary wheel 130. Therefore, the heat emitted by the condenser 140 can improve the drying effect of the rotary wheel 130, thereby realizing the high-efficiency dehumidification of the rotary dehumidifier 100.

[0056] It should be further explained that the above-mentioned liquid cooling heat exchange system further includes an expansion valve 180, a compressor 190 and the like, and the liquid cooling heat exchange system belongs to the common technical knowledge of those skilled in the art, therefore, it is not described in detail here.

[0057] Please refer to Figure 1 and Figure 5 In another embodiment, the rotary dehumidifier 100 further includes a heat absorption coil 160 located in the regenerative air duct 102.

[0058] The heat absorption coil 160 is arranged between the rotary wheel 130 and the regenerative air fan 150, and the heat absorption coil 160 and the cooling coil 121 constitute a double-zone cooling type liquid cooling heat exchange system.

[0059] It can be understood that the heat absorption coil 160 is used to absorb the heat of the air close to the rotary wheel 130 side, thereby avoiding overheating damage of the regenerative air fan 150.

[0060] Specifically, the cooling coil 121 is mainly used for cooling and dehumidifying the fresh air, and the heat absorption coil 160 is mainly used for cooling the air in the regenerative air duct 102, and the two coils work together to effectively ensure the humidity control of the air through their respective heat exchange effects.

[0061] Therefore, through the design of the double-zone cooling type liquid cooling heat exchange system, the overall working efficiency and energy utilization rate of the rotary dehumidifier 100 can be improved, thereby improving the energy utilization efficiency of the entire device, reducing energy waste, and increasing the reliability and economy of the device.

[0062] Optionally, as shown in Figure 4 The heat absorbing coil 160 and the cooling coil 121 are integrally formed and used as an evaporator in a heat exchange system.

[0063] Optionally, as shown in Figure 5 In order to meet the temperature requirements of different areas, the heat absorbing coil 160 and the cooling coil 121 are arranged in different areas respectively and used as two evaporators, and two refrigeration circuits are arranged to ensure independent control of the refrigeration temperature of the two areas.

[0064] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
