Description

Technical Field

[0001] The present invention relates to the field of dehumidification technology, and in particular to a moisture absorbing component, a dehumidification device and a dehumidification control method. Background Art

[0002] In the production process of lithium batteries, in order to ensure a comfortable environment and process requirements, the temperature, humidity and cleanliness of the workshop need to be strictly controlled. Dehumidifiers have the function of controlling temperature and cleanliness, so they are widely used in lithium battery production plants. The moisture absorption component in the dehumidifier needs to be regenerated by a heating device after absorbing a certain amount of moisture. However, in the related art, the moisture absorption component requires more energy consumption when it is in the regeneration stage. Summary of the invention

[0003] The main purpose of the present invention is to provide a dehumidification component, a dehumidification device and a dehumidification control method, aiming at reducing the energy consumption during the regeneration of the dehumidification component.

[0004] To achieve the above-mentioned purpose, the moisture absorption component proposed in the present invention includes a moisture absorption wheel, a vacuum device, a driving mechanism and a heater. The moisture absorption wheel is provided with at least two sub-areas. The vacuum device includes a vacuum pump and a vacuum cover, the vacuum cover is connected to the vacuum pump and is arranged opposite to at least one of the sub-areas of the moisture absorption wheel. The driving mechanism is connected to the vacuum cover in a transmission manner and drives the vacuum cover to move in a direction close to the moisture absorption wheel; or the driving mechanism drives the vacuum cover to move in a direction away from the moisture absorption wheel. The heater is arranged on the vacuum cover.

[0005] The technical solution of the present invention is to set at least two sub-areas on the hygroscopic wheel, and the vacuum cover of the vacuum device can be set opposite to at least one sub-area, the vacuum cover is connected to the vacuum pump, and the driving mechanism is connected to the vacuum cover in a transmission manner. Then, when the driving mechanism drives the vacuum cover to move to cover the hygroscopic wheel corresponding to it, a near-vacuum environment can be formed between the vacuum cover and the sub-area set opposite to it under the action of vacuum pump vacuuming. Therefore, the ambient air pressure of at least one sub-area of ​​the hygroscopic wheel can be reduced, thereby reducing the saturated evaporation temperature corresponding to this area, that is, the heating power consumed by the heater arranged on the vacuum cover is reduced, thereby achieving the effect of reducing energy consumption.

[0006] In addition, when the vacuum pump is evacuating the vacuum cover, the heater simultaneously heats up the environment inside the vacuum cover, so that the moisture in the sub-area of ​​the hygroscopic wheel corresponding to the vacuum cover will be rapidly desorbed and discharged through the outlet of the vacuum pump, eliminating the need for regeneration exhaust equipment, thereby reducing the waste of energy by taking away the heat from the hygroscopic wheel. By driving the vacuum cover away from the hygroscopic wheel through the driving mechanism, the area of ​​the hygroscopic wheel corresponding to the vacuum cover can be separated from the relatively vacuum environment, so that the process of absorbing moisture from the nearby air can be carried out normally.

[0007] In one embodiment, the moisture absorption component further comprises a rotary motor, which is in transmission connection with the moisture absorption wheel to drive the moisture absorption wheel to rotate. The driving mechanism is electrically connected to the rotary motor; and / or the heater is electrically connected to the rotary motor.

[0008] Such arrangement reduces the need for manual rotation of the moisture absorption wheel, saves labor costs, and achieves the effect of automatically driving the moisture absorption wheel to rotate.

[0009] In one embodiment, the vacuum device further comprises a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is connected to the vacuum pump, and the other end is connected to the vacuum cover. One end of the second connecting pipe is connected to the vacuum cover, and the other end is connected to the outside.

[0010] By setting up a first connecting pipe, one end of which is connected to the vacuum pump and the other end is connected to the vacuum cover, the vacuum pump can be installed outside the dehumidification device using the desiccant component, so that when the vacuum pump extracts the gas containing water vapor, the risk of water vapor remaining in the dehumidification device and being adsorbed by the desiccant wheel again can be reduced.

[0011] By connecting one end of the second connecting pipe to the vacuum hood and the other end to the outside, the vacuum hood can also communicate with the outside atmosphere, so that the driving mechanism can drive the vacuum hood away from the moisture absorption wheel more easily, reducing the energy consumption of the driving mechanism.

[0012] In one embodiment, at least a portion of the first connecting pipe is a bellows.

[0013] Such an arrangement reduces the risk of the vacuum cover causing the first connecting pipe to become loose from the vacuum pump during movement, or reduces the risk of the vacuum cover causing the first connecting pipe to become loose from the vacuum pump during movement.

[0014] In one embodiment, a first control valve is disposed on the first connecting pipe, and a second control valve is disposed on the second connecting pipe.

[0015] With such a setting, it is convenient to implement the action of automatically controlling the evacuation of the vacuum chamber or the effect of separating the vacuum chamber from the moisture absorption rotor.

[0016] In one embodiment, the moisture absorption assembly further includes a fixed bracket, the moisture absorption rotor is rotatably arranged on the fixed bracket, a first sensor is further arranged on the fixed bracket, and a limiting member for the first sensor to sense is arranged in each sub-region. The first sensor is electrically connected to the rotating motor.

[0017] With such a setting, it can be realized that whenever a sub-region corresponds to the first sensor, the rotating motor can be in a stopped state, so as to further control the driving mechanism to drive the vacuum chamber to move towards the moisture absorption rotor to evacuate and heat the sub-region on the moisture absorption rotor opposite to the vacuum chamber, so as to make the regeneration process of this sub-region effective.

[0018] In one embodiment, a sealing gasket is installed on one side of the vacuum chamber facing the moisture absorption rotor. When the vacuum chamber seals and covers the moisture absorption rotor, the sealing gasket is clamped between the vacuum chamber and the moisture absorption rotor.

[0019] With such a setting, the degree of vacuum of the evacuation can be improved, and then the evaporation temperature of water vapor can be reduced as much as possible, so as to reduce the energy consumption during the regeneration process of the moisture absorption assembly.

[0020] In one embodiment, a second sensor is installed on one side of the vacuum chamber facing the moisture absorption rotor, and both the driving mechanism and the vacuum pump are electrically connected to the second sensor.

[0021] With such a setting, it can be determined whether the vacuum chamber has contacted the moisture absorption rotor according to the detection of the second sensor. When the second sensor detects whether the vacuum chamber has contacted the moisture absorption rotor, the driving mechanism stops driving the vacuum chamber, and the vacuum pump is turned on and starts to evacuate the space covered by the vacuum chamber, so as to improve the automation degree and regeneration efficiency of the regeneration process of the moisture absorption assembly.

[0022] In one embodiment, the moisture absorption assembly further includes a support frame body, and the driving mechanism is arranged on the support frame body.

[0023] With such a setting, the installation of the driving mechanism is more stable, and the driving mechanism is closer to the vacuum chamber and the moisture absorption rotor, so as to facilitate the realization of the precise driving effect of the vacuum chamber.

[0024] In one embodiment, the driving mechanism includes a plurality of pneumatic valves, and the plurality of pneumatic valves are arranged at intervals along the circumference of the vacuum chamber.

[0025] With such a setting, when multiple pneumatic valves work together, they can drive the vacuum hood to move simultaneously, ensuring that almost all positions of the vacuum hood come into contact with the moisture absorption rotor at the same time, and thus making the fitting degree between various parts of the vacuum hood and the moisture absorption rotor relatively equivalent.

[0026] In one embodiment, the vacuum hood includes a first half hood and a second half hood. The openings of the first half hood and the second half hood are arranged opposite to each other, and the first half hood and the second half hood are respectively disposed on opposite sides of the moisture absorption rotor.

[0027] With such a setting, the sealing performance of at least part of the area of the moisture absorption rotor is improved, and the efficiency of the vacuum pump for evacuating is increased.

[0028] The present invention also provides a dehumidification device, including the above-mentioned moisture absorption assembly.

[0029] The present invention also provides a dehumidification control method based on the above-mentioned moisture absorption assembly. The dehumidification control method includes:

[0030] Controlling the driving mechanism to start to drive the vacuum hood to move towards the direction close to the moisture absorption rotor;

[0031] Controlling the vacuum pump to start and controlling the heater to start.

[0032] By controlling the driving mechanism to start to drive the vacuum hood to move towards the direction close to the moisture absorption rotor and controlling the vacuum pump to start, the space in the vacuum hood can be evacuated to reduce the evaporation temperature, thereby reducing the power consumption of the heater; by controlling the heater to start, the environment in the vacuum hood can be heated, so that the moisture on the moisture absorption rotor evaporates, achieving the effect of regenerating at least part of the area of the moisture absorption rotor.

[0033] By driving the vacuum hood to move through the driving mechanism, the vacuum hood can have a state close to the moisture absorption rotor and a state separated from the moisture absorption rotor, thus facilitating the flexible selection of at least part of the sub-regions of the moisture absorption rotor being in the regeneration stage or all sub-regions being in the adsorption state.

[0034] In one embodiment, before the step of controlling the vacuum pump to start and controlling the heater to start, it further includes:

[0035] Obtaining that the vacuum hood is in a state of sealing and covering the moisture absorption rotor.

[0036] With such a setting, it is ensured that the vacuum pump and the heater are started after the vacuum hood seals and covers the moisture absorption rotor, which can reduce the energy consumption of the vacuum pump and the heater before the vacuum hood covers the moisture absorption rotor.

[0037] In one embodiment, a pressure sensor is provided on one side of the vacuum hood facing the moisture absorption rotating wheel; the step of obtaining the state that the vacuum hood seals and covers the moisture absorption rotating wheel includes:

[0038] Obtain the pressure value of the pressure sensor, compare the pressure value with a preset pressure threshold, and generate a first comparison result;

[0039] Judge the state of the vacuum hood according to the first comparison result;

[0040] Under the condition that the first comparison result is that the pressure value is not less than the preset pressure threshold, it is determined that the vacuum hood is in the state of sealing and covering the moisture absorption rotating wheel.

[0041] With such a setting, it can adapt to the situation where one side of the vacuum hood facing the moisture absorption rotating wheel is worn. Even if one side of the vacuum hood facing the moisture absorption rotating wheel is worn, as long as the pressure value measured by the pressure sensor is not less than the preset pressure threshold, it can be determined that the vacuum hood and the moisture absorption rotating wheel are closely attached, that is, the vacuum hood is in the state of sealing and covering the moisture absorption rotating wheel, thereby improving the accuracy of judging the state of the vacuum hood.

[0042] In one embodiment, after the steps of controlling the vacuum pump to start and controlling the heater to start, the following steps are further included:

[0043] Obtain the running time of the vacuum pump and the heater, compare the running time with a preset time, and generate a second comparison result;

[0044] Under the condition that the second comparison result is that the running time reaches the preset time, control the vacuum pump and the heater to turn off, and control the driving mechanism to start to drive the vacuum hood away from the moisture absorption rotating wheel.

[0045] By obtaining the running time of the vacuum pump and the heater, and comparing the running time with the preset time to generate a second comparison result, it can be determined whether the regeneration process of the sub-region covered by the vacuum hood is completed. When the second comparison result is that the running time reaches the preset time, it is determined that the running time of the vacuum pump and the heater is long enough, and the regeneration process of the sub-region covered by the vacuum hood is completed. At this time, by controlling the vacuum pump and the heater to turn off, the energy consumption of the vacuum pump and the heater can be reduced.

[0046] In addition, by controlling the driving mechanism to start to drive the vacuum hood away from the moisture absorption rotating wheel, it is convenient for the sub-region that has completed the regeneration process to continue to adsorb moisture in the surrounding environment in a timely manner, improving the adsorption efficiency.

[0047] In one embodiment, before the step of controlling the driving mechanism to start and drive the vacuum hood to move towards the direction close to the moisture absorption rotor, the following steps are further included:

[0048] It is obtained that the moisture absorption rotor is in a stopped state.

[0049] With such a setting, the vacuum hood can stably and effectively perform targeted regeneration treatment on the corresponding sub-region, thereby improving the regeneration treatment efficiency of the sub-region.

[0050] In one embodiment, the moisture absorption component further includes a rotating motor, and the rotating motor is in transmission connection with the moisture absorption rotor; after the step of controlling the vacuum pump and the heater to be turned off and controlling the driving mechanism to start to drive the vacuum hood away from the moisture absorption rotor under the condition that the second comparison result is that the operation duration reaches the preset duration, the following steps are further included:

[0051] Control the rotating motor to start.

[0052] With such a setting, the sub-regions that have undergone regeneration treatment can be in different positions at different times, and thus the moisture in the surrounding environment can be adsorbed more comprehensively, thereby improving the moisture absorption efficiency.

[0053] In one embodiment, the moisture absorption component further includes a fixed bracket, the moisture absorption rotor is rotatably arranged on the fixed bracket, and a first sensor is further arranged on the fixed bracket. Each sub-region is provided with a limiting member for the first sensor to sense; after the step of controlling the rotating motor to start, the following steps are further included:

[0054] When it is obtained that the first sensor senses the limiting member, control the moisture absorption rotor to stop rotating.

[0055] With such a setting, the effect that each sub-region can be regenerated can be achieved, so that the moisture absorption rotor can continuously adsorb the moisture in the surrounding environment, improving the moisture absorption efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0076] During the production process of batteries, in order to ensure a comfortable environment and process requirements, it is necessary to strictly control the temperature, humidity, and cleanliness of the workshop. The dehumidification equipment has the function of controlling humidity, so it is widely used in lithium battery production plants. The moisture absorption component in the dehumidification equipment needs to be regenerated by a heating device after adsorbing a certain amount of moisture. In the related art, the adsorption dehumidification principle is to use adsorption materials such as alumina and silica gel to make a loose and porous rotating wheel. When air flows through the rotating wheel, the adsorbent has a strong adsorption effect on moisture and adsorbs the moisture in the air. As the rotating wheel rotates, the area where adsorption is approaching saturation turns into the regeneration area. In the regeneration area, the rotating wheel is heated by high-temperature regeneration air, and the moisture adsorbed in the rotating wheel vaporizes and evaporates, and the adsorbent is regenerated and becomes dry. As the rotating wheel rotates, the rotating wheel enters the adsorption area, and the dry adsorbent adsorbs the moisture in the air again.

[0077] However, the wheel is cooled in the adsorption zone by the chilled water supplied by the refrigeration unit in the plant. The temperature in the regeneration zone is raised by heating equipment such as electric heating, steam heating, and hot oil heating. When entering the regeneration zone from the adsorption zone, the alternation of hot and cold has a great impact on the loss of energy consumption. Secondly, the regeneration wind takes away a lot of heat when leaving the dehumidifier, which also has a certain impact on the operating energy consumption of the dehumidifier. Therefore, the moisture absorption component in the related art needs to consume more energy when it is in the regeneration stage.

[0078] In order to reduce the energy consumption of the moisture absorption component during the regeneration stage, the present invention provides a moisture absorption component.

[0079] Please refer to Figures 1 to 4 In one embodiment of the present invention, the moisture absorption assembly includes a moisture absorption wheel 100, a vacuum device 200, a driving mechanism 300 and a heater 400. The moisture absorption wheel 100 is provided with at least two sub-areas 101. The vacuum device 200 includes a vacuum pump 210 and a vacuum cover 220, the vacuum cover 220 is connected to the vacuum pump 210, and is arranged opposite to at least one sub-area 101 of the moisture absorption wheel 100. The driving mechanism 300 is connected to the vacuum cover 220 in a transmission manner, and drives the vacuum cover 220 to move in a direction close to the moisture absorption wheel 100; or, the driving mechanism 300 drives the vacuum cover 220 to move in a direction away from the moisture absorption wheel 100. The heater 400 is arranged on the vacuum cover 220.

[0080] The moisture absorption rotor 100 refers to a rotor body that can rotate and absorb moisture in the environment. The rotor can include a fixing ring and a moisture absorption main body disposed within the fixing ring, and this arrangement can improve the strength of the rotor. The fixing ring can be made of metal, plastic, or other materials. The moisture absorption main body is made of a hydrophilic material, such as asbestos, fiberglass, paper material, etc. Of course, in another example, if the strength requirement for the rotor is not high, the rotor can also only include a circular moisture absorption main body. The moisture absorption rotor 100 is provided with at least two sub-regions 101. For example, the moisture absorption rotor 100 can be provided with two sub-regions 101, three sub-regions 101, or more sub-regions 101, etc. The areas of the respective sub-regions 101 of the moisture absorption rotor 100 can be equal or unequal. In order to have a good regeneration effect on each sub-region 101, the respective sub-regions 101 can be set to the same size. By providing at least two sub-regions 101, the vacuum hood 220 of the vacuum device 200 can be relatively arranged only for one or several of the sub-regions 101, so as to perform regeneration processing; while the other sub-regions 101 not opposite to the vacuum hood 220 of the vacuum device 200 can continue to absorb moisture in the environment. In order to be able to divide each region of the moisture absorption rotor 100, based on the above-mentioned rotor arrangement with a fixing ring, the rotor can also be provided with support bars, and the support bars are distributed in a circular array and connected to the fixing ring, so as to form a sub-region 101 between every two adjacent support bars.

[0081] The vacuum device 200 refers to a device capable of performing vacuum pumping. The vacuum device 200 includes a vacuum pump 210 and a vacuum hood 220. The vacuum pump 210 refers to a pump body capable of providing power for the vacuum pumping action. The vacuum hood 220 refers to a hood structure for forming a vacuum environment. The opening shape of the vacuum hood 220 can be the same as the shape of the sub-region 101 of the moisture absorption rotor 100, that is, it can be fan-shaped or semi-circular. Or the opening shape of the vacuum hood 220 can also be different from the shape of the sub-region 101 of the moisture absorption rotor 100. For example, the opening shape of the vacuum hood 220 can be rectangular, circular or triangular, etc., as long as the vacuum hood 220 can be opposite to the moisture absorption rotor 100. It can be understood that, in order to maximize the regeneration treatment of each sub-region 101 of the moisture absorption rotor 100, the opening shape of the vacuum hood 220 can be set to be the same as the shape and size of the sub-region 101 of the moisture absorption rotor 100. When the vacuum hood 220 is connected to the vacuum pump 210, it can be directly connected or indirectly connected. When the vacuum hood 220 is indirectly connected to the vacuum pump 210, the vacuum device 200 can also include a connecting pipe, and the vacuum hood 220 and the vacuum pump 210 are connected through the connecting pipe. The moisture absorption rotor 100 has two end faces arranged oppositely. Among them, the moisture absorption rotor 100 can provide moisture absorption function only on one end face, and the other end face is supported by a non-moisture-absorbing material, such as metal or plastic; at this time, the vacuum hood 220 of the vacuum device 200 can be arranged only opposite to the end face capable of absorbing moisture in the environment. Of course, both end faces of the moisture absorption rotor 100 arranged oppositely can provide moisture absorption function. At this time, two vacuum hoods 220 can be provided for the vacuum device 200, or the vacuum hood 220 has a structure similar to a U shape, so that the vacuum hood 220 can seal or have a gap on both sides opposite to the moisture absorption rotor 100, so that the area where the moisture absorption rotor 100 is opposite to the vacuum hood 220 can form a region with a lower air pressure, thereby facilitating the reduction of the evaporation temperature in this region and achieving a good regeneration effect. It can be understood that when the vacuum pump 210 evacuates the space between the vacuum hood 220 and the moisture absorption rotor 100, the environmental air pressure here is lowered, so the effect of reducing the saturated temperature of water vapor can be achieved. For example, when a traditional regeneration device without a vacuum device 200 regenerates the moisture absorption rotor 100, it is necessary to heat the regeneration part to 100 °C or even higher than 100 °C to convert the moisture on the moisture absorption rotor 100 into water vapor; in this application, by setting the vacuum device 200, taking an environment of -80 kPa as an example, the evaporation temperature of water vapor can be reduced to 60 °C, so the heating power of the heater 400 can be reduced, thereby achieving the effect of reducing energy consumption. In addition, in this application, there is no need to set a regeneration exhaust device, so the risk of taking away a large amount of heat on the moisture absorption rotor 100 during the exhaust process can be reduced, and the energy consumption of the dehumidification device using this moisture absorption component is further reduced.

[0082] The driving mechanism 300 refers to a mechanism that drives the vacuum cover 220 to move in a direction away from the moisture absorption wheel 100 and in a direction close to the moisture absorption wheel 100. When the driving mechanism 300 drives the vacuum cover 220 to move, it can drive the vacuum cover 220 to do translational motion, and it can also drive the vacuum cover 220 to do rotational motion, so that the vacuum cover 220 has a state close to the moisture absorption wheel 100 and a state away from the moisture absorption wheel 100 to avoid the rotation of the moisture absorption wheel 100. When the driving mechanism 300 drives the vacuum cover 220 to do translational motion, the driving mechanism 300 may include a cylinder or a pneumatic valve 310, or the driving mechanism 300 includes a lead screw nut assembly, a gear rack assembly or a linear motor, etc. When the driving mechanism 300 drives the vacuum cover 220 to do rotational motion, the driving mechanism 300 may include a driving motor and a connecting rod assembly, or may include a driving motor and a gear assembly, etc. It should be noted that since the above examples of the driving mechanism 300 are all well-known technologies to those skilled in the art, they will not be described in detail. When there are two vacuum covers 220, and the two vacuum covers 220 are respectively opposite to the two opposite end surfaces of the moisture absorption wheel 100, each vacuum cover 220 can be connected to a driving mechanism 300; or the two vacuum covers 220 are connected to the same driving mechanism 300, that is, one driving mechanism 300 can simultaneously drive the two vacuum covers 220 to move in the direction close to the moisture absorption wheel 100 or drive the two vacuum covers 220 to move in the direction away from the moisture absorption wheel 100. When the driving mechanism 300 drives the vacuum cover 220 to move in the direction close to the moisture absorption wheel 100, a gap can be set between the vacuum cover 220 and the moisture absorption wheel 100, as long as the air pressure between the vacuum cover 220 and the corresponding sub-area 101 is lower than the air pressure near other sub-areas 101 in the starting state of the vacuum pump 210, so as to achieve the effect of regenerating the corresponding sub-area 101. At the same time, the moisture absorption wheel 100 can be in a rotating state or a stopped state in the regeneration state. Alternatively, when the driving mechanism 300 drives the vacuum cover 220 to move toward the direction close to the moisture absorption wheel 100, there may be no gap between the vacuum cover 220 and the moisture absorption wheel 100, that is, the vacuum cover 220 can seal the sub-area 101 of the moisture absorption wheel 100 that is arranged opposite to the vacuum cover 220, thereby improving the vacuum pump 210's vacuum pumping efficiency. At the same time, the moisture absorption wheel 100 may be in a state of stopping rotation; of course, after the vacuum cover 220 seals and covers the moisture absorption wheel 100 and still allows the vacuum cover 220 to rotate, the moisture absorption wheel 100 may also rotate synchronously with the vacuum cover 220, that is, the moisture absorption wheel 100 can still be in a state of rotating in the regeneration state.

[0083] The heater 400 is a device for heating the environment in the vacuum cover 220. The heater 400 can be arranged inside the vacuum cover 220 or outside the vacuum cover 220. When the vacuum cover 220 covers the moisture absorption wheel 100 to form an almost completely vacuum state, the heater 400 can use a radiation heating method, for example, the heater 400 is a microwave heater 400. Alternatively, when the vacuum cover 220 is not completely a vacuum environment, the heater 400 can also use convection heating or heat conduction heating methods, for example, the heater 400 can be a heating wire or other heating devices.

[0084] The technical solution of the present invention is to set at least two sub-areas 101 on the moisture absorption wheel 100, and the vacuum cover 220 of the vacuum device 200 can be set relative to at least one sub-area 101, the vacuum cover 220 is connected to the vacuum pump 210, and the driving mechanism 300 is connected to the vacuum cover 220 in a transmission connection. Then, when the driving mechanism 300 drives the vacuum cover 220 to move so as to gradually approach the corresponding moisture absorption wheel 100, under the vacuum pump 210, a relatively vacuum environment can be gradually formed between the vacuum cover 220 and the sub-area 101 covered by it. Therefore, the ambient air pressure of at least one sub-area 101 of the moisture absorption wheel 100 can be reduced, thereby reducing the saturated evaporation temperature corresponding to this area, that is, the heating power consumed by the heater 400 arranged on the vacuum cover 220 is reduced, thereby achieving the effect of reducing energy consumption. In addition, during the process of the vacuum pump 210 evacuating the vacuum cover 220, the heater 400 simultaneously heats up the environment in the vacuum cover 220, so that the moisture in the sub-area 101 of the hygroscopic wheel 100 corresponding to the vacuum cover 220 will be rapidly desorbed and desorbed, so that the water vapor is discharged along the outlet of the vacuum pump 210, eliminating the regeneration exhaust device, thereby reducing the waste of energy by taking away the heat on the hygroscopic wheel 100. By driving the vacuum cover 220 to move away from the hygroscopic wheel 100 through the driving mechanism 300, the area of ​​the hygroscopic wheel 100 corresponding to the vacuum cover 220 can be separated from the relatively vacuum environment, so that the process of absorbing moisture in the nearby air can be carried out normally.

[0085] In some embodiments of the present invention, the moisture absorption assembly further includes a rotary motor (not shown), which is in transmission connection with the moisture absorption wheel 100 to drive the moisture absorption wheel 100 to rotate. The driving mechanism 300 is electrically connected to the rotary motor; and / or the heater 400 is electrically connected to the rotary motor.

[0086] The rotating motor refers to a component that provides power for the rotation of the moisture absorption runner 100. The rotating motor can be directly connected to the moisture absorption runner 100 through a transmission connection, or can be connected through other transmission components. When the rotating motor is directly connected to the moisture absorption runner 100 through a transmission connection, a shaft sleeve for inserting the output shaft of the rotating motor is provided in the middle of the moisture absorption runner 100. The shaft sleeve and the output shaft of the rotating motor can be connected by a key, or the shaft sleeve adopts a non-circular structure to cooperate with the output shaft, so as to achieve the effect of directly connecting the moisture absorption runner 100 and the rotating motor through a transmission connection, thereby simplifying the structure of the moisture absorption component. When the rotating motor is connected to the moisture absorption runner 100 through other transmission components, the transmission components can be a connecting rod component or a gear component, etc., so that the transmission ratio can be changed through the transmission components, and then the effect of adjusting the angular velocity of the moisture absorption runner 100 can be achieved, so as to ensure that the moisture absorption runner 100 rotates within a suitable range of rotational angular velocity, thereby achieving a better moisture absorption effect.

[0087] If the driving mechanism 300 is electrically connected to the rotating motor, the effect of controlling the driving mechanism 300 to change its motion state can be achieved through the state of the rotating motor. Specifically, in one example, when the rotating motor is in a normal operating state, that is, when the rotating motor drives the moisture absorption runner 100 to rotate, the driving mechanism 300 can be controlled to be in a stopped state, so that the vacuum cover 220 is kept at a certain distance from the moisture absorption runner 100, so as to avoid the risk of the vacuum cover 220 interfering with the rotation of the moisture absorption runner 100. When the rotating motor is in a stopped state, the driving mechanism 300 can be started and driven to move the vacuum cover 220 in the direction close to the moisture absorption runner 100 and approach at least one sub-region 101 of the moisture absorption runner 100, so as to achieve the effect of automatically controlling whether the vacuum cover 220 of the vacuum device 200 seals the moisture absorption runner 100 to regenerate the region sealed by the vacuum cover 220 according to the state of the rotating motor or the moisture absorption runner 100. Of course, in other examples, when the rotating motor drives the moisture absorption runner 100 to rotate, the driving mechanism 300 can also drive the vacuum cover 220 to move in the direction of the moisture absorption runner 100, so that during the rotation of the moisture absorption runner 100, its different sub-regions 101 are respectively arranged opposite to the vacuum cover 220 at different times, so as to achieve the effect of regenerating different sub-regions 101 in real time.

[0088] By drivingly connecting the rotary motor to the dehumidifying rotary wheel 100 and electrically connecting the driving mechanism 300 to the rotary motor, on the one hand, the rotary motor can be used to drive the dehumidifying rotary wheel 100 to rotate, reducing the situation of manually rotating the dehumidifying rotary wheel 100, saving labor costs, achieving the effect of automatically driving the dehumidifying rotary wheel 100 to rotate, and ensuring the stability of the rotation speed of the dehumidifying rotary wheel 100. By electrically connecting the driving mechanism 300 to the rotary motor, the driving mechanism 300 and the rotary motor can control each other, so that the driving mechanism 300 can be controlled according to the state of the rotary motor, and further the effect of controlling whether the regeneration treatment is carried out can be achieved.

[0089] As Figure 3 shown, in an embodiment of the present invention, the vacuum device 200 further includes a first communication pipe 230 and a second communication pipe 240. One end of the first communication pipe 230 is connected to the vacuum pump 210, and the other end is connected to the vacuum hood 220. One end of the second communication pipe 240 is connected to the vacuum hood 220, and the other end is connected to the outside.

[0090] The first communication pipe 230 refers to a pipeline used to connect the vacuum pump 210 and the vacuum hood 220. The first communication pipe 230 can be linear or curved. The first communication pipe 230 can be made of metal or plastic.

[0091] The second communication pipe 240 refers to a pipeline used to connect the vacuum hood 220 and the outside. The first communication pipe 230 can be linear or curved. The first communication pipe 230 can be made of metal or plastic. It should be noted that when it is necessary to evacuate the inside of the vacuum hood 220, the second communication pipe 240 in the present invention is in a state of being isolated from the external environment, that is, the second communication pipe 240 is in a blocked state. For example, the second communication pipe 240 can be controlled to be in a blocked state by an electromagnetic valve provided on the second communication pipe 240, or the second communication pipe 240 can be blocked by installing a sealing plug or a sealing column at the end of the second connection pipe away from the vacuum hood 220; and the first communication pipe 230 can be provided with a first electromagnetic valve or not. When the dehumidifying rotary wheel 100 needs to rotate, the vacuum pump 210 can be turned off or the first electromagnetic valve provided on the first communication pipe 230 can be changed to connect the second communication pipe 240 to the outside. At this time, the state of the electromagnetic valve can be controlled to control the second communication pipe 240 to connect the vacuum hood 220 to the outside, or the vacuum hood 220 can be connected to the outside by removing the sealing plug or the sealing column at the end of the second communication pipe 240 away from the vacuum hood 220. Of course, in other examples, a switching valve can be provided. The switching valve has at least three ports, and the three ports are respectively connected to the vacuum hood 220, the outside, and the vacuum pump 210. By changing the state of the switching valve, the effect of connecting the vacuum hood 220 to the outside or connecting the vacuum hood 220 to the vacuum pump 210 can be achieved.

[0092] By connecting one end of the first connecting pipe 230 to the vacuum pump 210 and the other end to the vacuum hood 220, the flexibility of the installation position of the vacuum pump 210 can be improved, and the situation where the driving mechanism 300 needs to drive the vacuum pump 210 to move synchronously when driving the vacuum hood 220 can be reduced, thereby reducing the energy consumption of the driving mechanism 300. In addition, with such an arrangement, the vacuum pump 210 can be disposed outside the dehumidifying device using this moisture absorption assembly. Thus, when the vacuum pump 210 pumps out the gas with water vapor, the risk that the water vapor remains in the dehumidifying device and is adsorbed by the moisture absorption rotor 100 again can be reduced. By connecting one end of the second connecting pipe 240 to the vacuum hood 220 and the other end to the outside, the vacuum hood 220 can communicate with the outside atmosphere, making it easier for the driving mechanism 300 to drive the vacuum hood 220 away from the moisture absorption rotor 100 and reducing the energy consumption of the driving mechanism 300.

[0093] As Figure 3 shown, in an embodiment of the present invention, at least a part of the first connecting pipe 230 is a corrugated pipe.

[0094] By setting at least a part of the first connecting pipe 230 as a corrugated pipe, the corrugated pipe can be bent and deformed in any direction, and thus the vacuum pump 210 can be placed more flexibly. In addition, with such an arrangement, the first connecting pipe 230 can also have the ability of telescopic deformation, reducing the risk that the first connecting pipe 230 and the vacuum pump 210 become loose from each other during the movement of the vacuum hood 220, or reducing the risk that the vacuum hood 220 and the first connecting pipe 230 become loose from each other during the movement.

[0095] As Figure 3 shown, in an embodiment of the present invention, a first control valve 250 is provided on the first connecting pipe 230, and a second control valve 260 is provided on the second connecting pipe 240.

[0096] The first control valve 250 refers to a valve used to control the on-off of the first connecting pipe 230, which can be an electromagnetic valve or an electric valve, etc.

[0097] The second control valve 260 refers to a valve used to control the on-off of the second connecting pipe 240, which can be an electromagnetic valve or an electric valve, etc.

[0098] By providing the first control valve 250 on the first connecting pipe 230 and the second control valve 260 on the second connecting pipe 240, it is possible to control the first connecting pipe 230 to be in a connected state or the second connecting pipe 240 to be in a connected state by controlling the states of the first control valve 250 and the second control valve 260, thereby facilitating the realization of the automatic control of the operation of evacuating the vacuum hood 220 or facilitating the effect that the vacuum hood 220 disengages from the moisture absorption rotor 100.

[0099] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, the moisture absorption component further includes a fixing bracket (not shown), the moisture absorption rotating wheel 100 is rotatably arranged on the fixing bracket, a first sensor 500 is further arranged on the fixing bracket, and a limiting member for the first sensor 500 to sense is arranged in each sub-region 101. The first sensor 500 is electrically connected to the rotation motor.

[0100] The fixing bracket refers to a frame structure for supporting the rotating wheel. The fixing bracket may include a support base and a mounting portion arranged on the support base, and the moisture absorption rotating wheel 100 is rotatably arranged on the mounting portion. The mounting portion may be annular or arc-shaped, or the mounting portion may include a column and a rotating shaft arranged at an angle with the column, etc.

[0101] The first sensor 500 refers to a sensor for sensing the rotation position or angle of the moisture absorption rotating wheel 100. The first sensor 500 may be a mechanical sensor, a magnetic sensor, an optoelectronic sensor, etc.

[0102] The limiting member refers to a component provided in each sub-region 101 for the first sensor 500 to sense. For example, in one example, the first sensor 500 is a mechanical sensor. When the first sensor 500 is a microswitch, the limiting member can be a limiting rod or a limiting piece provided on each sub-region 101. During the rotation of the moisture absorption rotor 100, whenever the limiting member of a sub-region 101 touches the microswitch, and the microswitch receives the signal that the moisture absorption rotor 100 has rotated in place, the microswitch can transmit the signal and control the rotation motor to be in a shutdown state. Then, the driving mechanism 300 is controlled to drive the vacuum hood 220 to move towards the moisture absorption rotor 100 to gradually approach the area corresponding to the moisture absorption rotor 100. Subsequently, the vacuum pump 210 evacuates the gas in the vacuum hood 220 and the heater 400 heats the environment in the vacuum hood 220 to automatically achieve the effect of regenerating the area covered by the vacuum hood 220. In another example, the first sensor 500 can also be an optoelectronic sensor. The limiting member provided in each sub-region 101 can be a limiting rod. When the moisture absorption rotor 100 is rotating, when the limiting rod of a sub-region 101 passes through the optoelectronic sensor, and the optoelectronic sensor senses that a limiting rod has passed, it indicates that a new sub-region 101 is set opposite to the vacuum hood 220. At this time, the signal can be transmitted to the rotation motor through the optoelectronic sensor to control the rotation motor to be in a shutdown state. Then, the driving mechanism 300 is controlled to drive the vacuum hood 220 to move towards the moisture absorption rotor 100 to gradually approach the area corresponding to the moisture absorption rotor 100. In yet another example, the first sensor 500 is a magnetic induction probe, and the limiting member provided in each sub-region 101 is a magnet. When the magnet of a sub-region 101 corresponds to the magnetic induction probe during rotation, the magnetic induction probe receives and senses the magnet, indicating that a new sub-region 101 is set opposite to the vacuum hood 220. At this time, the signal can be transmitted to the rotation motor through the magnetic induction probe to control the rotation motor to be in a shutdown state. Then, the driving mechanism 300 is controlled to drive the vacuum hood 220 to move towards the moisture absorption rotor 100 to gradually approach the area corresponding to the moisture absorption rotor 100.

[0103] By rotatably arranging the moisture absorption rotor 100 on a fixed bracket, a first sensor 500 is provided on the fixed bracket, and a limiting member for the first sensor 500 to sense is provided in each sub-region 101. When the limiting member in each sub-region 101 rotates to a position corresponding to the first sensor 500 during the rotation of the moisture absorption rotor 100, the first sensor 500 can sense it. Therefore, when each sub-region 101 rotates to correspond to the first sensor 500, different sub-regions 101 will correspond to the vacuum hood 220. By electrically connecting the first sensor 500 to the rotating motor, the state of the rotating motor can be controlled through the signal obtained by the first sensor 500. Furthermore, whenever a sub-region 101 corresponds to the first sensor 500, the rotating motor can be in a stop state, so as to further control the driving mechanism 300 to drive the vacuum hood 220 to move towards the moisture absorption rotor 100 to perform vacuum pumping and heating treatment on the sub-region 101 of the moisture absorption rotor 100 opposite to the vacuum hood 220, thereby enabling the regeneration process of this sub-region 101.

[0104] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, a sealing gasket 600 is installed on the side of the vacuum hood 220 facing the moisture absorption rotor 100. When the vacuum hood 220 seals and covers the moisture absorption rotor 100, the sealing gasket 600 is clamped between the vacuum hood 220 and the moisture absorption rotor 100.

[0105] The sealing gasket 600 refers to a component used to seal the gap between the vacuum hood 220 and the rotor. The sealing gasket 600 can be made of rubber or silica gel. When the sealing gasket 600 is arranged on the side of the vacuum hood 220 facing the moisture absorption rotor 100, it can be connected to the vacuum hood 220 by connection methods such as bonding, welding, and clamping.

[0106] By clamping the sealing gasket 600 between the vacuum hood 220 and the moisture absorption rotor 100, the sealing performance between the vacuum hood 220 and the moisture absorption rotor 100 can be improved. Thus, when evacuating the area where the vacuum hood 220 covers the moisture absorption rotor 100 under the action of the vacuum pump 210, the evacuation efficiency can be improved, and the evacuation vacuum degree can also be improved. Furthermore, the evaporation temperature of water vapor can be reduced as much as possible, thereby reducing the energy consumption during the regeneration process of the moisture absorption component.

[0107] In an embodiment of the present invention, a second sensor (not shown) is installed on the side of the vacuum hood 220 facing the moisture absorption rotor 100. Both the driving mechanism 300 and the vacuum pump 210 are electrically connected to the second sensor.

[0108] The second sensor refers to a detection component that is used to sense the position of the vacuum cover 220 to further determine whether the vacuum cover 220 reaches a position where it fits with the moisture absorption runner 100 after moving a certain distance or for a certain period of time. The second sensor can be a pressure sensor, a photoelectric sensor, or other sensors.

[0109] When the second sensor is a photoelectric sensor, such as an infrared sensor, the second sensor can be fixedly arranged on the inner wall of the vacuum cover 220 or on the end face of the vacuum cover 220 facing the moisture absorption runner 100. The distance between the vacuum cover 220 and the moisture absorption runner 100 is detected by the pressure sensor to achieve the effect of judging whether the vacuum cover 220 moves in place to fit with the moisture absorption runner 100. For example, when the second sensor is embedded on the side of the vacuum cover 220 facing the moisture absorption runner 100 and is flush with the end face of the vacuum cover 220 facing the moisture absorption runner 100, if the second sensor senses that the distance from the end face of the vacuum cover 220 facing the moisture absorption runner 100 to the end face of the moisture absorption runner 100 is zero, it is determined that the vacuum cover 220 and the moisture absorption runner 100 are fitted together. At this time, the second sensor can transmit this signal to the driving mechanism 300 and the vacuum pump 210. After receiving this signal, the driving mechanism 300 stops driving the vacuum cover 220, and after receiving this signal, the vacuum pump 210 starts to evacuate the space covered by the vacuum cover 220 on the moisture absorption runner 100.

[0110] When the second sensor is a pressure sensor, the pressure sensor can be disposed on the inner wall of the vacuum cover 220 or on the end face of the vacuum cover 220 close to the moisture absorption runner 100. By detecting the mutual abutting force between the vacuum cover 220 and the moisture absorption runner 100 through the pressure sensor, the effect of judging whether the vacuum cover 220 moves in place to fit with the moisture absorption runner 100 can be achieved; when the mutual abutting force between the vacuum cover 220 and the moisture absorption runner 100 detected by the pressure sensor reaches a preset pressure value, the signal is transmitted to the driving mechanism 300 and the vacuum pump 210. After receiving the signal, the driving mechanism 300 stops driving the vacuum cover 220, and after receiving the signal, the vacuum pump 210 starts to perform a vacuum pumping action on the space covered by the vacuum cover 220 for the moisture absorption runner 100. It can be understood that since the end face of the vacuum cover 220 close to the moisture absorption runner 100 may be worn, the scheme of determining the contact between the vacuum cover 220 and the moisture absorption runner 100 by limiting the stroke of the vacuum cover 220 may result in the situation that the vacuum cover 220 cannot fit tightly with the moisture absorption runner 100. When the second sensor is a pressure sensor, the risk that the vacuum cover 220 is difficult to fit tightly with the moisture absorption runner 100 due to wear can be avoided. By installing a second sensor on the side of the vacuum cover 220 facing the moisture absorption runner 100, the position of the vacuum cover 220 when moving in the direction close to the moisture absorption runner 100 can be sensed by the second sensor, so as to facilitate judging whether the vacuum cover 220 and the moisture absorption runner 100 are in a mutually fitting or tightly attached state, and further accurately control whether the vacuum pump 210 starts.

[0111] By installing a second sensor on the side of the vacuum cover 220 facing the moisture absorption runner 100, and both the driving mechanism 300 and the vacuum pump 210 are electrically connected to the second sensor, it can be determined whether the vacuum cover 220 has contacted the moisture absorption runner 100 according to the detection of the second sensor. When the second sensor detects that the vacuum cover 220 has contacted the moisture absorption runner 100, the driving mechanism 300 stops driving the vacuum cover 220, and the vacuum pump 210 is turned on and starts to perform a vacuum pumping action on the space covered by the vacuum cover 220. In this way, the automation degree and regeneration efficiency of the regeneration process of the moisture absorption component are improved, the risk of the vacuum cover 220 hitting the moisture absorption runner 100 is reduced, and the effect of timely regenerating at least one sub-region 101 of the moisture absorption runner 100 is achieved.

[0112] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the moisture absorption component further includes a support frame body 270, and the driving mechanism 300 is disposed on the support frame body 270.

[0113] The support frame 270 refers to a frame structure for supporting the driving mechanism 300. The support frame 270 may include a support structure formed in a block, disc or columnar structure. The support frame 270 may be made of metal or plastic.

[0114] By arranging the driving mechanism 300 on the support frame 270 , the installation of the driving mechanism 300 can be made more stable, and the driving mechanism 300 can be made closer to the vacuum cover 220 and the moisture absorption wheel 100 , thereby facilitating the precise driving effect of the vacuum cover 220 .

[0115] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the driving mechanism 300 includes a plurality of pneumatic valves 310 , and the plurality of pneumatic valves 310 are arranged at intervals along the circumference of the vacuum cover 220 .

[0116] The pneumatic valve 310 refers to a valve driven by compressed air. The pneumatic valve 310 is composed of an actuator and a regulating mechanism. The actuator is the thrust component of the pneumatic valve 310, that is, the mechanism that enables the pneumatic valve 310 to move. The valve body is the regulating component of the pneumatic valve 310, which is in direct contact with the regulating medium, adjusts the flow rate of the fluid, and makes the pressure in the valve body different according to the flow rate of the fluid, and then generates corresponding thrust according to the size of the pressure, pushing the vacuum cover 220 to move. Multiple pneumatic valves 310 refer to two pneumatic valves 310, three pneumatic valves 310 or more pneumatic valves 310.

[0117] By making the driving mechanism 300 include a plurality of pneumatic valves 310, the structure of the driving mechanism 300 is relatively simple, and the pneumatic valves 310 can be used to push the vacuum cover 220 to move, and the effect of controlling the movement stroke of the vacuum cover 220 can be achieved, so as to ensure that the vacuum cover 220 can contact with the moisture absorption wheel 100 and form a closed space together after reaching the preset stroke. By arranging the plurality of pneumatic valves 310 at intervals along the circumference of the vacuum cover 220, the plurality of pneumatic valves 310 can simultaneously drive the vacuum cover 220 to move when working in coordination, so as to ensure that each position of the vacuum cover 220 contacts the moisture absorption wheel 100 almost at the same time, and furthermore, the degree of contact between each position of the vacuum cover 220 and the moisture absorption wheel 100 is relatively equal.

[0118] In one embodiment of the present invention, the vacuum cover 220 includes a first half cover (not shown) and a second half cover (not shown), the opening of the first half cover and the opening of the second half cover are arranged opposite to each other, and the first half cover and the second half cover are respectively covered on opposite sides of the moisture absorption wheel 100.

[0119] The first half-cover refers to a part of the cover body of the vacuum cover 220, and the volume of the first half-cover can be half or close to half of the volume of the entire vacuum cover 220. The shape of the first half-cover can be circular, triangular, fan-shaped or other shapes.

[0120] The second half-cover refers to a part of the cover body of the vacuum cover 220, and the volume of the second half-cover can be half or close to half of the volume of the entire vacuum cover 220. The shape of the second half-cover can be circular, triangular, fan-shaped or other shapes.

[0121] The shapes of the first half-cover and the second half-cover can be the same or different. The volumes of the first half-cover and the second half-cover can be the same or different. The first half-cover and the second half-cover can be arranged separately or integrally. It can be understood that when the first half-cover and the second half-cover are arranged separately, it is convenient to replace the first half-cover or the second half-cover, thereby reducing the replacement cost. At this time, the first half-cover and the second half-cover can be driven by the same driving mechanism 300 or different driving mechanisms 300.

[0122] By arranging the openings of the first half-cover and the second half-cover opposite to each other, and the first half-cover and the second half-cover are respectively disposed on opposite sides of the moisture absorption rotor 100, the first half-cover and the second half-cover can jointly seal and cover opposite sides of the moisture absorption rotor 100, thereby improving the sealing performance of at least part of the area of the moisture absorption rotor 100 and improving the pumping efficiency of the vacuum pump 210.

[0123] The present invention also provides a dehumidification device, including a moisture absorption component, and the specific structure of the moisture absorption component refers to the above-mentioned embodiments. Since this dehumidification device adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.

[0124] With such a setting, when the driving mechanism 300 drives the vacuum hood 220 to move to cover the corresponding moisture absorption rotor 100, under the action of the vacuum pump 210 to evacuate the air, an environment close to vacuum can be formed between the vacuum hood 220 and the sub-region 101 covered by it. Therefore, the ambient air pressure of at least one sub-region 101 of the moisture absorption rotor 100 can be reduced, so that the saturation evaporation temperature corresponding to this region is reduced, that is, the heating power consumed by the heater 400 provided on the vacuum hood 220 is reduced, and thus the effect of reducing energy consumption is achieved. In addition, during the process of the vacuum pump 210 evacuating the vacuum hood 220, the heater 400 simultaneously raises the temperature of the environment inside the vacuum hood 220, so that the moisture at the sub-region 101 of the moisture absorption rotor 100 corresponding to the vacuum hood 220 will be quickly desorbed, so that the water vapor is discharged along the outlet of the vacuum pump 210, eliminating the need for a regeneration exhaust device, and thus reducing the waste of energy by taking away the heat on the moisture absorption rotor 100.

[0125] The present invention also provides a dehumidification control method based on the above-mentioned moisture absorption component. Since the moisture absorption component on which this dehumidification control method is based adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, as Figure 5 shown, the dehumidification control method includes:

[0126] S30: Control the driving mechanism 300 to start, so as to drive the vacuum hood 220 to move in the direction close to the moisture absorption rotor 100.

[0127] By controlling the driving mechanism 300 to start and driving the vacuum hood 220 to move in the direction close to the moisture absorption rotor 100, the vacuum hood 220 can gradually approach at least one sub-region 101 of the moisture absorption rotor 100, thus providing a good environment for the subsequent evacuation action of the vacuum pump 210. The driving device can drive the vacuum hood 220 to perform a translational motion, or can also drive the vacuum hood 220 to rotate to approach at least one sub-region 101 of the moisture absorption rotor 100.

[0128] S50: Control the vacuum pump 210 to start and control the heater 400 to start.

[0129] After the vacuum hood 220 moves close to the moisture absorption rotor 100, the vacuum device 200 is controlled to start, so as to achieve the effect of evacuating the space covered by the vacuum hood 220, thereby reducing the air pressure inside the vacuum hood 220, reducing the evaporation temperature, and facilitating the reduction of the energy consumed during the regeneration of the moisture absorption rotor 100. Specifically, in one example, the vacuum pump 210 and / or the heater 400 can be started during the movement of the vacuum hood 220 towards the moisture absorption rotor 100. It can be understood that after the vacuum hood 220 moves close to the moisture absorption rotor 100, by controlling the heater 400 to start, the heater 400 can heat the environment inside the vacuum hood 220. Thus, when the moisture at the sub-region 101 of the moisture absorption rotor 100 opposite to the vacuum hood 220 is heated to the evaporation temperature corresponding to the current air pressure value, it turns into water vapor and is discharged with the vacuum pump 210, thereby achieving the regeneration effect of the sub-region 101 of the moisture absorption rotor 100 corresponding to the vacuum hood 220. Of course, in another example, the vacuum pump 210 and the heater 400 can also be controlled to start after the vacuum hood 220 completely covers at least one sub-region 101 of the moisture absorption rotor 100, thereby improving the vacuum pumping efficiency of the vacuum pump 210 and reducing the energy consumption of the vacuum pump 210 and the heater 400.

[0130] By controlling the driving mechanism 300 to start to drive the vacuum hood 220 to move towards the moisture absorption rotor 100, and by controlling the vacuum pump 210 to start, the space formed between the vacuum hood 220 and the corresponding sub-region 101 on the moisture absorption rotor 100 can be evacuated, so that the air pressure in this space is reduced, and further the evaporation temperature is reduced, achieving the effect of reducing the power consumption of the heater 400. By controlling the heater 400 to start, the environment inside the vacuum hood 220 can be heated, so that the moisture on the moisture absorption rotor 100 evaporates, achieving the effect of regenerating at least part of the region of the moisture absorption rotor 100. In addition, by driving the vacuum hood 220 to move through the driving mechanism 300, the vacuum hood 220 can be in a state close to the moisture absorption rotor 100 and a state of separating from the moisture absorption rotor 100, thereby facilitating the flexible selection of at least part of the sub-regions 101 of the moisture absorption rotor 100 to be in the regeneration stage or all the sub-regions 101 to be in the adsorption state.

[0131] As Figure 6 shown, in an embodiment of the present invention, before the step S50: controlling the vacuum pump 210 to start and controlling the heater 400 to start, it further includes:

[0132] S40: Obtaining that the vacuum hood 220 is in a state of hermetically covering the moisture absorption rotor 100.

[0133] When obtaining the state where the vacuum chamber 220 covers the moisture absorption rotor 100 in a sealed manner, it can be specifically detected by an airtight detector, or can be detected by a distance sensor, a pressure sensor, etc.

[0134] With such a setting, after the vacuum chamber 220 covers the moisture absorption rotor 100 in a sealed manner, then starting the vacuum pump 210 and the heater 400 can reduce the energy consumption of the vacuum pump 210 and the heater 400 before the vacuum chamber 220 covers the moisture absorption rotor 100.

[0135] As Figure 7 shown, in an embodiment of the present invention, a pressure sensor is provided on one side of the vacuum chamber 220 facing the moisture absorption rotor 100; the step S40 of obtaining the state where the vacuum chamber 220 covers the moisture absorption rotor 100 in a sealed manner includes:

[0136] S41: Obtain the pressure value of the pressure sensor, compare the pressure value with a preset pressure threshold, and generate a first comparison result.

[0137] Specifically, the preset pressure threshold can be set to any value greater than zero. The pressure value detected by the pressure sensor is the current pressure value between the vacuum chamber 220 and the moisture absorption rotor 100. When the pressure value detected by the pressure sensor is larger, it indicates that the mutual abutting force between the vacuum chamber 220 and the moisture absorption rotor 100 is larger, and thus it can be determined that the vacuum chamber 220 is tightly attached to the moisture absorption rotor 100. Compare the pressure value with the preset pressure threshold and generate a first comparison result. The first comparison result may be that the pressure value is less than the preset pressure threshold; the first comparison result may also be that the pressure value is greater than or equal to the preset pressure threshold.

[0138] S42: According to the first comparison result, judge the state of the vacuum chamber 220.

[0139] According to different first comparison results, the state of the vacuum chamber 220 is also different. Specifically, when the first comparison result is that the pressure value is less than the preset pressure threshold, the vacuum chamber 220 does not reach the preset fitting degree with the moisture absorption rotor 100; when the first comparison result is that the pressure value is greater than or equal to the pressure threshold, the vacuum chamber 220 reaches the preset fitting degree with the moisture absorption rotor 100.

[0140] S43: Under the condition that the first comparison result is that the pressure value is not less than the preset pressure threshold, determine that the vacuum chamber 220 is in the state of covering the moisture absorption rotor 100 in a sealed manner.

[0141] When the first comparison result indicates that the pressure value is not less than the preset pressure threshold, it means that the vacuum cover 220 and the moisture absorption rotor 100 are tightly fitted. Therefore, it can be determined that the vacuum cover 220 is in the state of sealing and covering the moisture absorption rotor 100. Furthermore, the vacuum pump 210 can be further controlled to evacuate the environment inside the vacuum cover 220 based on the state of the vacuum cover 220.

[0142] By obtaining the pressure value of the pressure sensor, comparing the pressure value with the preset pressure threshold and generating the first comparison result, and judging the state of the vacuum cover 220 according to the first comparison result. When the first comparison result indicates that the pressure value is not less than the preset pressure threshold, it is determined that the vacuum cover 220 is in the state of sealing and covering the moisture absorption rotor 100. Then, the degree of fit between the vacuum cover 220 and the moisture absorption rotor 100 can be indirectly judged by the pressure value detected by the pressure sensor. When the first comparison result indicates that the pressure value is not less than the preset pressure threshold, it means that the current mutual holding force between the vacuum cover 220 and the moisture absorption rotor 100 is relatively large. Thus, it is determined that the vacuum cover 220 and the moisture absorption rotor 100 are in a tightly fitted state, which is convenient for sending a signal to the vacuum pump 210 to evacuate the environment inside the vacuum cover 220. In addition, with such a setting, it can also adapt to the situation where the side of the vacuum cover 220 facing the moisture absorption rotor 100 is worn. Even if the side of the vacuum cover 220 facing the moisture absorption rotor 100 is worn, as long as the pressure value measured by the pressure sensor is not less than the preset pressure threshold, it can be determined that the vacuum cover 220 and the moisture absorption rotor 100 are already tightly fitted, that is, the vacuum cover 220 is in the state of sealing and covering the moisture absorption rotor 100, thereby improving the accuracy of judging the state of the vacuum cover 220.

[0143] As Figure 8 shown, in an embodiment of the present invention, after the step S50: controlling the vacuum pump 210 to start and controlling the heater 400 to start, the following steps are further included:

[0144] S60: Obtain the operation duration of the vacuum pump 210 and the heater 400, compare the operation duration with the preset duration, and generate a second comparison result.

[0145] After the vacuum pump 210 starts, it begins to evacuate the area covered by the vacuum cover 220. When the operation duration of the vacuum pump 210 is longer, the air pressure inside the vacuum cover 220 is lower, thus getting closer to a vacuum environment. Furthermore, the evaporation temperature of water vapor becomes lower and lower, and it becomes easier to remove the moisture from the sub-region 101 of the moisture absorption rotor 100 covered by the vacuum cover 220.

[0146] After the heater 400 is started, it is used to heat the environment inside the vacuum cover 220. The longer the heating duration is, the more moisture in the sub-region 101 of the moisture absorption rotor 100 covered by the vacuum cover 220 is converted into water vapor and discharged with the vacuum pump 210. Therefore, after the vacuum pump 210 and the heater 400 both operate for a certain period of time, the sub-region 101 of the moisture absorption rotor 100 covered by the vacuum cover 220 reaches the state of complete regeneration.

[0147] S70: Under the condition that the second comparison result is that the operation duration reaches the preset duration, control the vacuum pump 210 and the heater 400 to turn off, and control the drive mechanism 300 to start to drive the vacuum cover 220 away from the moisture absorption rotor 100.

[0148] The preset duration refers to a set reference value when the sub-region 101 of the moisture absorption rotor 100 covered by the vacuum cover 220 reaches the state of complete regeneration. When the operation duration reaches the preset duration, it means that the operation durations of the vacuum pump 210 and the heater 400 are relatively long, and the sub-region 101 of the moisture absorption rotor 100 covered by the vacuum cover 220 has fully reached the state of complete regeneration. At this time, there is no need to evacuate and heat the space covered by the vacuum cover 220 anymore. After the sub-region 101 covered by the vacuum cover 220 completes the regeneration state, it can continue to adsorb moisture in the surrounding environment.

[0149] By obtaining the operation durations of the vacuum pump 210 and the heater 400, and comparing the operation durations with the preset duration to generate a second comparison result, it can be determined whether the regeneration process of the sub-region 101 covered by the vacuum cover 220 is completed. When the second comparison result is that the operation duration reaches the preset duration, it is determined that the start durations of the vacuum pump 210 and the heater 400 are long enough, and the sub-region 101 covered by the vacuum cover 220 has completed the regeneration process. At this time, by controlling the vacuum pump 210 and the heater 400 to turn off, the energy consumption of the vacuum pump 210 and the heater 400 can be reduced. In addition, by controlling the drive mechanism 300 to start to drive the vacuum cover 220 away from the moisture absorption rotor 100, it is convenient for the sub-region 101 that has completed the regeneration process to continue to adsorb moisture in the surrounding environment in a timely manner, improving the adsorption efficiency.

[0150] Such as Figure 8 shown, before the step S30: controlling the drive mechanism 300 to start to drive the vacuum cover 220 to move in the direction close to the moisture absorption rotor 100, it further includes:

[0151] S10: It is obtained that the moisture absorption rotor 100 is in a stopped state.

[0152] Specifically, when the moisture absorption rotor 100 is driven by a rotating motor, the state of the moisture absorption rotor 100 can be obtained by acquiring the current state of the rotating motor. When it is acquired that the rotating motor is in the normal working state of being powered on, it is determined that the moisture absorption rotor 100 is in a rotating state; when it is acquired that the rotating motor is in a powered-off state, it is determined that the moisture absorption rotor 100 is in a stopped state. When the moisture absorption rotor 100 is not driven by a rotating motor, a marking portion can be provided on the moisture absorption rotor 100, and the moisture absorption assembly further includes a sensor for detecting the marking portion. If the sensor has not been able to detect the marking portion within a preset time period, it is determined that the moisture absorption rotor 100 is in a stopped state; if the marking portion can be detected within the preset time period, it is determined that the moisture absorption rotor 100 is in a rotating state. It should be noted that the time period for the moisture absorption rotor 100 to rotate one week at a specified angular velocity can be used as the preset time period, or a time period greater than the time for the moisture absorption rotor 100 to rotate one week at a specified angular velocity can be used as the preset time period, etc.

[0153] After it is acquired that the moisture absorption rotor 100 is in a stopped state and then the vacuum hood 220 is driven to move towards the moisture absorption rotor 100, the vacuum hood 220 can stably and effectively perform targeted regeneration treatment on the corresponding sub-region 101, thereby improving the regeneration treatment efficiency of the sub-region 101.

[0154] As Figure 8 shown, in an embodiment of the present invention, the moisture absorption assembly further includes a rotating motor, and the rotating motor is in transmission connection with the moisture absorption rotor 100. After the step S70: under the condition that the second comparison result is that the operation time reaches the preset time period, controlling the vacuum pump 210 and the heater 400 to be turned off, and controlling the driving mechanism 300 to start to drive the vacuum hood 220 away from the moisture absorption rotor 100, the following steps are further included:

[0155] S80: Control the rotating motor to start.

[0156] By controlling the rotating motor to start, the moisture absorption rotor 100 is in a rotating state, so that the sub-region 101 that has undergone regeneration treatment can be in different positions at different times, and thus the moisture in the surrounding environment can be adsorbed more comprehensively, thereby improving the moisture absorption efficiency.

[0157] As Figure 8 shown, in an embodiment of the present invention, the moisture absorption assembly further includes a fixed bracket, the moisture absorption rotor 100 is rotatably arranged on the fixed bracket, and a first sensor 500 is further arranged on the fixed bracket, and each sub-region 101 is provided with a limiting member for the first sensor 500 to sense; after the step S80: controlling the rotating motor to start, the following steps are further included:

[0158] S90: When it is obtained that the first sensor 500 senses the position-limiting member, control the dehumidifying rotor 100 to stop rotating.

[0159] The first sensor 500 refers to a sensor used to sense the rotation position or angle of the dehumidifying rotor 100. The first sensor 500 can be a mechanical sensor, a magnetic sensor, an optoelectronic sensor, etc.

[0160] The position-limiting member refers to a component provided in each sub-region 101 and used for the first sensor 500 to sense. For example, in one example, the first sensor 500 is a mechanical sensor. For example, when the first sensor 500 is a microswitch, the position-limiting member can be a position-limiting rod or a position-limiting piece provided on each sub-region 101. During the rotation of the dehumidifying rotor 100, whenever the position-limiting member of a sub-region 101 touches the microswitch, after the microswitch receives the signal that the dehumidifying rotor 100 has rotated in place, the microswitch can transmit the signal and control the rotation motor to be in a shutdown state, and then control the driving mechanism 300 to drive the vacuum hood 220 to move towards the dehumidifying rotor 100 to seal and cover the corresponding area of the dehumidifying rotor 100. Subsequently, the vacuum pump 210 evacuates the gas in the vacuum hood 220 and heats the environment in the vacuum hood 220 through the heater 400 to automatically realize the effect of regenerating the area covered by the vacuum hood 220. In another example, the first sensor 500 can also be an optoelectronic sensor, and the position-limiting member provided in each sub-region 101 can be a position-limiting rod. When the dehumidifying rotor 100 is rotating, when the position-limiting rod of a sub-region 101 passes through the optoelectronic sensor, after the optoelectronic sensor senses that there is a position-limiting rod passing by, it indicates that a sub-region 101 and the vacuum hood 220 are oppositely arranged. At this time, the optoelectronic sensor can transmit this signal to the rotation motor to control the rotation motor to be in a shutdown state, and then control the driving mechanism 300 to drive the vacuum hood 220 to move towards the dehumidifying rotor 100 to seal and cover the corresponding area of the dehumidifying rotor 100. In yet another example, the first sensor 500 is a magnetic induction probe, and the position-limiting member provided in each sub-region 101 is a magnet. When the magnet of a sub-region 101 corresponds to the magnetic induction probe during rotation, the magnetic induction probe receives and senses the magnet, which indicates that a sub-region 101 and the vacuum hood 220 are oppositely arranged. At this time, the magnetic induction probe can transmit this signal to the rotation motor to control the rotation motor to be in a shutdown state, and then control the driving mechanism 300 to drive the vacuum hood 220 to move towards the dehumidifying rotor 100 to seal and cover the corresponding area of the dehumidifying rotor 100.

[0161] By controlling the rotation of the moisture absorption rotating wheel 100, during the rotation of the moisture absorption rotating wheel 100, the limit members of each sub-region 101 will be sequentially sensed by the first sensor 500 on the fixed bracket. By controlling the moisture absorption rotating wheel 100 to stop rotating when the first sensor 500 senses the limit member, the moisture absorption rotating wheel 100 can achieve a state of stopping after rotating a certain angle. Furthermore, when it is obtained that the moisture absorption rotating wheel 100 is in a stopped state, the drive mechanism 300 is further controlled to drive the vacuum hood 220 to move towards the moisture absorption rotating wheel 100, and the vacuum pump 210 and the heater 400 are started to perform vacuum pumping and heating treatment on the current sub-region 101 of the moisture absorption rotating wheel 100 that is oppositely arranged to the vacuum hood 220, so as to achieve the effect of regenerating this sub-region 101. The moisture absorption rotating wheel 100 rotates and stops, stops and rotates, and so on in a cycle, so that each sub-region 101 can achieve the effect of being regenerated, so that the moisture absorption rotating wheel 100 can continuously adsorb moisture in the surrounding environment, improving the moisture absorption efficiency.
