[0002] A rotary dehumidifier relies on the dehumidification wheel's slow, continuous rotation. The dehumidification wheel's moisture absorption channels in a three-quarter sector absorb water vapor from the air, reducing the air's moisture content. Simultaneously, heated air is introduced into the moisture absorption channels in the remaining quarter, removing the absorbed water vapor and restoring the moisture absorption capacity of the channels. This allows the dehumidification wheel to continuously dehumidify the air as it rotates.

[0003] In existing dehumidifier technology, a disc-shaped rotor is generally used for dehumidification, and a regeneration mechanism is set at part of the disc-shaped rotor to regenerate the rotor. The regeneration mechanism will block part of the disc-shaped rotor, reducing the air inlet surface of the disc-shaped rotor, resulting in a reduced dehumidification effect of the dehumidifier.

[0039] The present invention will be further described below with reference to the embodiments, but is not limited to the contents of the description.

[0040] like Figures 1 to 6 As shown, the present invention discloses a dehumidifier, comprising: a housing 1, on which an air inlet 11 is provided; a rotor 2, which is rotatably disposed within the housing 1; a regeneration mechanism 3, which is disposed within the housing 1, and the portion of the rotor 2 away from the air inlet 11 is located within the regeneration mechanism 3; a condensation wall 4, which is disposed between the rotor 2 and the air inlet 11 and is connected to the regeneration mechanism 3 to form a regeneration circulation channel, and a through-hole 41 is provided on the condensation wall 4, through which the airflow from the air inlet 11 flows to the rotor 2. The condensation wall 4 is disposed between the air inlet 11 and the rotor 2, and the regeneration mechanism 3 is disposed on the portion of the rotor 2 away from the air inlet 11, effectively solving the problem of the regeneration component blocking the rotor 2, thereby improving the dehumidification efficiency of the rotor 2 and enhancing the dehumidification effect of the dehumidifier. Figure 5 The direction of the solid arrow in the figure is the dehumidification flow direction of the gas.

[0041] Specifically, the housing 1 is provided with an air outlet 12, and the cross-section of the rotor 2 is annular. The annular rotor 2 can ensure that the rotor 2 can be smoothly regenerated by the regeneration mechanism 3 when the position of the regeneration mechanism 3 remains unchanged, and the gas from the air inlet 11 enters the interior of the rotor 2 from the side of the rotor 2 and flows to the air outlet 12 from the end of the rotor 2. At this time, the airflow from the air inlet 11 can pass through the rotor 2 from the portion of the rotor 2 close to the air inlet 11 and enter the interior of the rotor 2. Since the portion of the rotor 2 away from the air inlet 11 is located in the regeneration mechanism 3, the regeneration mechanism 3 does not affect the airflow through the rotor 2, that is, it does not affect the air inlet area of ​​the rotor 2, thereby ensuring the dehumidification efficiency of the rotor 2.

[0042] To ensure that airflow can flow through the portion of the rotor 2 near the air inlet 11 and be discharged from the end of the rotor 2, the dehumidifier further includes an exhaust fan 9. The air outlet 12 is located above the rotor 2. The exhaust fan 9 is located at the air outlet 12, and the axis of the exhaust fan 9 is collinear with the axis of the rotor 2. Because the regeneration mechanism 3 blocks part of the rotor 2, airflow can only pass through the rotor 2 near the air inlet 11 and enter the interior of the rotor 2, preventing air from entering every position of the rotor 2 and affecting the dehumidification efficiency of the rotor 2.

[0043] The cross section of the condensation wall 4 is annular, and the condensation wall 4 surrounds the rotor 2, and the portion of the condensation wall 4 away from the air inlet 11 is connected to the regeneration mechanism 3. The use of the annular condensation wall 4 can minimize the space occupied by the condensation wall 4 in the interior of the housing 1, solving the problem of redundant structure. At the same time, when the airflow in the regeneration circulation channel passes through the annular condensation wall 4, the centrifugal force effect brought by the annular shape can increase the heat exchange efficiency between the airflow and the gas blowing toward the condensation wall 4, accelerate the condensation of the airflow in the regeneration circulation channel, and further improve the dehumidification efficiency of the rotor 2. Figure 6 As shown, the direction of the solid arrow is the direction of the air flow in the regeneration circulation flow channel.

[0044] In order to further improve the dehumidification effect of the dehumidifier, the dehumidifier further includes a condenser 5 and an evaporator. The condenser 5 and the evaporator are both arranged between the rotor 2 and the condensation wall 4, and the evaporator is located between the condensation wall 4 and the condenser 5. The refrigerant is used to dehumidify the airflow, thereby realizing a composite dehumidifier and further improving the dehumidification efficiency.

[0045] The dehumidifier further includes a compressor 7, which is sequentially connected to the condenser 5 and the evaporator 6 to form a refrigerant heat exchange cycle. The refrigerant discharged from the compressor 7 passes through the condenser 5 and the evaporator 6 in sequence before returning to the compressor 7, completing the refrigerant heat exchange cycle. The gas entering the air inlet 11 first passes through the evaporator 6 for dehumidification, then passes through the condenser 5 and exchanges heat with the refrigerant in the condenser 5, ensuring the normal operation of the refrigerant heat exchange cycle. The gas after passing through the condenser 5 is further dehumidified by passing through the rotor 2, and is finally discharged through the end of the rotor 2 and the air outlet 12, completing the dehumidification of the gas.

[0046] like Figure 1 As shown, the compressor 7 is located below the wheel 2, thereby rationally arranging the structure inside the dehumidifier and further improving the structural compactness of the dehumidifier.

[0047] Optionally, the housing 1 further includes a base, and the compressor 7 is disposed on the base.

[0048] The dehumidifier further includes a drive mechanism, which is provided on the compressor 7 and can drive the wheel 2 to rotate. Specifically, the drive mechanism includes a motor and a transmission gear, which is provided on the wheel 2. The output gear of the motor meshes with the transmission gear, thereby driving the wheel 2 to rotate.

[0049] The dehumidifier further includes a water receiving mechanism 8, which is located below the condensation wall 4 and the evaporator 6 and is used to receive the condensed water from the condensation wall 4 and / or the condensed water from the evaporator 6. The water receiving mechanism 8 is used to receive the condensed water generated during the dehumidification process, thereby ensuring the reliable operation of the dehumidifier. Figure 5 or Figure 6 As shown, the hollow arrow direction is the flow direction of condensed water.

[0050] Specifically, the water receiving mechanism 8 includes a water receiving tray and a water tank. The water receiving tray is located below the evaporator 6 and the condensation wall 4. The condensed water formed by dehumidification of the evaporator 6 and the condensed water discharged by the condensation wall 4 are collected by the water receiving tray and sent to the water tank for storage.

[0051] The regeneration mechanism 3 includes a heating mechanism 31, which is disposed within the regeneration circulation channel. The airflow within the regeneration circulation channel sequentially passes through the heating mechanism 31 and the portion of the rotor 2 located within the regeneration circulation channel. The heating mechanism 31 heats the gas within the regeneration circulation channel, and the heated gas heats and regenerates the rotor 2 within the regeneration mechanism 3, thereby ensuring the dehumidification effect of the rotor 2.

[0052] The regeneration mechanism 3 also includes a regeneration fan, which is arranged in the regeneration circulation channel. The regeneration fan drives the gas to flow in the regeneration circulation channel. Preferably, the gas flowing through the impeller 2 located in the regeneration mechanism 3 passes through the regeneration fan.

[0053] The regeneration mechanism 3 includes a regeneration shell, on which a regeneration air inlet and a regeneration air outlet are provided. Both the regeneration air inlet and the regeneration air outlet are communicated with the condensation wall 4 .

[0054] The regeneration shell is also provided with an air supply port, and the gas in the shell 1 can be supplied into the regeneration circulation channel through the air supply port to ensure that the gas volume in the regeneration circulation channel meets the dehumidification demand and is conducive to the condensation water flowing out of the condensation wall 4.

[0055] In order to improve the structural compactness and aesthetics of the dehumidifier, the cross-section of the shell 1 is annular, the air inlet 11 is located on the side of the shell 1, the air outlet 12 is located on the end face of the shell 1, and the axis of the shell 1 is collinear with the axis of the wheel 2.

[0056] When the dehumidifier is performing dehumidification work, the air around the dehumidifier is sucked into the shell 1 through the air inlet 11 under the action of the exhaust fan 9, and passes through the condensation wall 4, evaporator 6, condenser 5, and rotor 2 in sequence to become dry gas, and is discharged from the shell 1 through the air outlet 12, completing the dehumidification process.

[0057] Another aspect of the present invention provides a control method for the above-mentioned dehumidifier, wherein the dehumidifier further includes a condenser 5, an evaporator 6, and a compressor 7. The condenser 5 and the evaporator 6 are both arranged between the runner 2 and the condensation wall 4, and the evaporator 6 is located between the condensation wall 4 and the condenser 5. The compressor 7 is sequentially connected to the condenser 5 and the evaporator 6 to form a refrigerant heat exchange cycle. The dehumidifier has a fast dehumidification mode:

[0058] When the dehumidifier is in rapid dehumidification mode, the compressor 7 and the regeneration mechanism 3 both start operating, and the rotor 2 starts rotating. At this time, the airflow entering the housing 1 is dehumidified by the dual action of the refrigerant and the rotor 2, maximizing the dehumidification efficiency and achieving rapid dehumidification.

[0059] The dehumidifier also includes a deep dehumidification mode:

[0060] When the dehumidifier is in deep dehumidification mode, obtaining the ambient temperature t1 and comparing t1 with the preset temperature t0;

[0061] If t1 ≥ t0, it indicates that the ambient temperature is too high, and the compressor 7 needs to be controlled to start working, and the refrigerant and the rotor 2 are dehumidified at the same time to improve the dehumidification efficiency;

[0062] If t1<t0, it indicates that the ambient temperature is relatively low at this time and only the rotor 2 needs to be dehumidified, then the regeneration mechanism 3 is controlled to start working and the rotor 2 is controlled to start rotating.

[0063] If t1≥t0, then after the compressor 7 is controlled to start working, the process further includes:

[0064] Obtain the ambient humidity φ1 and compare φ1 with the preset humidity φ0;

[0065] If φ1<φ0, the ambient humidity is low and the dehumidification efficiency of the refrigerant is low, then the regeneration mechanism 3 is controlled to start working, and the wheel 2 is controlled to start rotating, and the dual effects of the wheel 2 and the refrigerant are used to further reduce the ambient humidity and achieve a deep dehumidification effect.

[0066] Since the energy consumption of the refrigerant heat exchange cycle is relatively high, the dehumidifier also includes an energy-saving dehumidification mode:

[0067] When the dehumidifier is in energy-saving dehumidification mode, the ambient temperature t1 and the ambient humidity φ1 are obtained, and t1 is compared with the preset temperature t0, and φ1 is compared with the preset humidity φ0;

[0068] If t1<t0 or φ1<φ0, the regeneration mechanism 3 is controlled to start working, and the wheel 2 is controlled to start rotating;

[0069] If t1 ≥ t0 and φ1 ≥ φ0, the compressor 7 is controlled to start operating.

[0070] The value range of t0 is 15°C to 20°C, preferably 18°C.

[0071] The value of Φ0 ranges from 30% to 50%, preferably 40%.

[0072] It should be noted that when the water in the water tank reaches a preset height, the dehumidifier will shut down to avoid overflow problems.

[0073] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not possible to enumerate all embodiments here.
