detailed description

In order to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the embodiments of the present invention.

An embodiment of the present invention provides a dehumidification device, which can be applied to a refrigeration device. The refrigeration device includes a drying room. The dehumidification device in the refrigeration device may include a controller, and the communication device is disposed between the drying room and the drying room. And a first desiccant container located inside the switching mechanism. Here, the dehumidifying device is not limited to being used in refrigeration equipment such as a refrigerator, and may also be used in other equipment requiring dehumidification.

FIG. 1 is a schematic diagram of a position of a switching mechanism according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a circuit structure according to an embodiment of the present invention. Referring to FIG. Referring to FIG. 2, the controller 201 is connected to the switching mechanism 102; here, the controller 201 may be provided in the refrigeration equipment.

In the embodiment of the present invention, the drying chamber 101 is located in the refrigeration equipment, and the first desiccant container (not shown in FIG. 1) is located inside the switching mechanism 102. The first desiccant container stores a desiccant; here, the desiccant is configured as an adsorption chamber. Regarding the moisture in the drying chamber 101, the embodiment of the present invention does not limit the shape and material of the desiccant. For example, the shape of the desiccant may be granular or other shapes, and the material of the desiccant may be silica gel or other renewable materials. Desiccant material

The controller 201 is configured to send a first switching instruction to the switching mechanism 102;

The switching mechanism 102 is configured to switch the desiccant in the first desiccant container from the first communication state to the second communication state after receiving the first switching instruction, and the first communication state is in contact with the air in the drying room, And a state in which it is not in contact with the dry outdoor air; a second communication state is a state in which it is in contact with the dry outdoor air and is not in contact with the dry indoor air.

It should be noted that the first desiccant container is not a completely closed structure. In one example, at least one side of the first desiccant container is provided with an air vent. In this way, the air of the first desiccant container can be exchanged with the outside air. In another example, the shell of the first desiccant container is a mesh structure, so that the air of the first desiccant container can be exchanged with the outside air; it should be noted that when the shell of the first desiccant container is a mesh When the shape of the desiccant in the first desiccant container is granular, the particle size of the desiccant in the first desiccant container needs to be larger than the mesh size of the above-mentioned mesh structure to ensure that The desiccant does not leak out of the first desiccant container.

In practical applications, the controller 201 may be an Application Specific Integrated Circuit (ASIC), a DSP, a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), or an FPGA. At least one of a CPU, a controller, a microcontroller, and a microprocessor; the switching mechanism 102 may include a motor and a rotatable component. When the rotatable component rotates at different positions, the desiccant is in different communication states; in actual implementation The controller 201 can send a corresponding instruction to the motor, and the motor controls the rotatable component to rotate according to the received instruction. For example, after the motor receives the first switching instruction, it controls the rotatable component to rotate to turn the first desiccant. The desiccant in the container is switched from the first communication state to the second communication state.

It can be seen that, in the embodiment of the present invention, the desiccant can be used to adsorb moisture in the drying chamber. In this way, the drying chamber can be dried without using a compressor. Compared with technology, the temperature of the drying chamber does not need to be lowered, and the problem of relatively large humidity fluctuations in the drying chamber caused by the start and stop of the compressor can be avoided, which is beneficial for storing temperature-sensitive items and items that need to be stored in low humidity environments .

For the implementation manner in which the controller 201 sends the first switching instruction to the switching mechanism 102, in one example, the controller 201 is specifically configured to time the time when the desiccant in the first desiccant container is in the first communication state, and When the duration that the desiccant in the first desiccant container is in the first communication state is longer than the first preset duration, a first switching instruction is sent to the switching mechanism 102.

In actual implementation, the user can input the first timing instruction to the controller 201 through the human-computer interaction at the start time when it is determined that the desiccant in the first desiccant container is in the first communication state, and the controller receives the first timing instruction At that time, the time when the desiccant in the first desiccant container is in the first communication state can be started to be timed.

In the embodiment of the present invention, the controller 201 waits for the first preset period of time and then sends the first switching instruction to the switching mechanism 102 in order to make the desiccant in the first desiccant container fully absorb and dry within the first preset period of time. In this way, the moisture in the chamber 101 can be dried in the first desiccant container by switching the desiccant in the first desiccant container from the first communicating state to the second communicating state after the desiccant has sufficiently absorbed the moisture. The desiccant is fully in contact with the dry outdoor air; when the dry outdoor air is relatively dry, the moisture absorbed in the desiccant can be quickly released, so that the desiccant in the first desiccant container can be used again.

Here, the first preset time period can be set according to the moisture absorption capacity of the desiccant. The moisture absorption capacity of the desiccant is determined by the material of the desiccant, the shape of the desiccant, and the like. The shorter you can set the duration.

For an implementation manner in which the controller 201 sends the first switching instruction to the switching mechanism 102, in another example, the above-mentioned dehumidifying device may further include: a first humidity sensor in contact with the desiccant in the first desiccant container; thus, the first The humidity data collected by a humidity sensor is the humidity of the desiccant in the first desiccant container. Referring to FIG. 2, the data receiving end of the controller 201 is connected to the data output end of the first humidity sensor 202.

The controller 201 is specifically configured to receive the humidity data collected by the first humidity sensor 202, and when it is determined that the humidity data collected by the first humidity sensor 202 is greater than or equal to a first humidity threshold, send a first switching instruction to the switching mechanism 102.

Here, the first humidity threshold may be set according to the humidity when the desiccant is saturated with moisture, for example, the first humidity threshold is less than or equal to the humidity when the desiccant is saturated with moisture, and is greater than or equal to the set ratio and the humidity when the desiccant is saturated with moisture The product is set to a ratio less than 1. In one example, the ratio is set to a value between 50% and 1. It can be understood that the humidity when the desiccant is saturated with moisture is determined by the desiccant material and the desiccant. The shape is determined. In addition, the humidity when the desiccant is saturated with moisture can be measured in advance, that is, the humidity when the desiccant is saturated with moisture can be known in advance.

According to the content described above, it can be seen that when the humidity data from the first humidity sensor is greater than or equal to the first humidity threshold, the controller 201 sends a first switching instruction to the switching mechanism 102, which can be used in the first desiccant container. After the desiccant fully absorbs moisture, the desiccant in the first desiccant container can be brought into full contact with the drying outdoor air by switching the desiccant in the first desiccant container from the first communication state to the second communication state; When the outdoor air is relatively dry, the moisture absorbed in the desiccant in the first desiccant container can be quickly released, so that the desiccant in the first desiccant container can be used again.

Further, the controller 201 is further configured to send a second switching instruction to the switching mechanism 102 after sending the first switching instruction to the switching mechanism 102; and the switching mechanism 102 is further configured to send the first switching instruction to the first switching instruction after receiving the second switching instruction. The desiccant in the desiccant container is switched from the second communication state to the first communication state.

It can be understood that after the controller 201 sends the first switching instruction to the switching mechanism 102, the desiccant in the first desiccant container can be switched to the second communication state. At this time, when the dry outdoor air is relatively dry, the Quickly release the moisture absorbed in the desiccant in the first desiccant container; in this way, after the switching mechanism 102 switches the desiccant in the first desiccant container from the second connected state to the first connected state, as such, the first drying The desiccant in the desiccant container can absorb the moisture in the drying chamber 101 again to realize the recycling of the desiccant in the first desiccant container.

For the implementation manner in which the controller 201 sends the second switching instruction to the switching mechanism 102, in one example, the controller 201 is specifically configured to send a first switching instruction to the switching mechanism 102 to the desiccant in the first desiccant container. The time in the second connected state is counted, and when the length of the desiccant in the first desiccant container in the second connected state is longer than the second preset time period, a second switching instruction is sent to the switching mechanism 102.

In an embodiment, the controller 201 may determine the time when the first switching instruction is sent to the switching mechanism 102 as the start time when the desiccant in the first desiccant container is in the second connected state, that is, the controller 201 is switching to the After the mechanism 102 sends the first switching instruction, the timing is performed immediately to obtain the timing time when the desiccant in the dry first desiccant container is in the second connected state. In another embodiment, considering that the switching mechanism receives the first switching instruction, Time and the time when the switching mechanism switches the desiccant communication state in the first desiccant container, after the controller 201 sends the first switching instruction to the switching mechanism 102, waits for the first preset time interval, and then performs timing, The timing time of the desiccant in the first desiccant container in the second connected state is obtained. In this way, it can be ensured that when the controller starts timing, the desiccant in the first desiccant container is in the second connected state.

In actual implementation, the controller 201 may immediately time the second switching instruction sent to the switching mechanism 102 to obtain the timing time when the desiccant in the first desiccant container is in the first communication state; the controller 201 may also switch to the switching After the mechanism 102 sends the second switching instruction, it waits for the second preset time interval, and then performs timing to obtain the timing of the desiccant in the first desiccant container in the first communication state. In this way, it can ensure that the controller starts timing , The desiccant in the first desiccant container is in a first communication state.

In the embodiment of the present invention, the first preset time interval and the second preset time interval may be the same or different; and the duration that the desiccant in the first desiccant container is in the second connected state is longer than the second preset duration, It is switched to the first communication state. In this way, the moisture absorbed by the desiccant in the first desiccant container can be released as much as possible, so that the desiccant in the first desiccant container can be reused; the second preset time can be based on The material of the desiccant in the first desiccant container, the shape of the desiccant, the humidity of the drying outdoor air, and the like are determined.

For the implementation manner in which the controller 201 sends the second switching instruction to the switching mechanism 102, in another example, the controller 201 is specifically configured to receive the humidity data collected by the first humidity sensor 202 and determine the humidity collected by the first humidity sensor 202 When the data is less than or equal to the second humidity threshold, a second switching instruction is sent to the switching mechanism 102.

Here, the second humidity threshold is smaller than the first humidity threshold, and the second humidity threshold may be less than or equal to the product of the set ratio and the humidity when the desiccant is saturated with moisture; in a specific example, the first humidity threshold is the desiccant and saturated with moisture 80% of the humidity at the time, and the second humidity threshold is 20% of the humidity when the desiccant is saturated with moisture.

According to the content described above, it can be seen that when the humidity data collected by the first humidity sensor 202 is less than or equal to the second humidity threshold, the controller 201 sends a second switching instruction to the switching mechanism 102 to fully release the first desiccant. After the moisture in the desiccant in the container is switched, the desiccant in the first desiccant container is switched from the second connected state to the first connected state, so that the desiccant in the first desiccant container can re-moisturize the moisture in the drying chamber. Adsorption is performed to realize recycling of the desiccant in the first desiccant container.

Further, referring to FIG. 1, the above-mentioned dehumidifying device may further include a fan 103 disposed in the drying chamber 101 or the switching mechanism 102, and the controller 201 is further configured to control the operation of the fan 103.

It can be understood that when the controller 201 controls the fan 103 to work, the air circulation in the drying chamber 101 or the switching mechanism 102 can be accelerated; when the desiccant in the first desiccant container is in the first communication state, the drying chamber 101 is accelerated The air circulation inside can accelerate the speed of the desiccant in the first desiccant container to adsorb the moisture in the air in the drying chamber 101, and improve the moisture adsorption efficiency of the desiccant in the first desiccant container.

Further, the above-mentioned dehumidifying device may further include a heating element configured to heat the desiccant, for example, the heating element may be a polyimide film (PI) electric heating film; for the location of the heating element, in one example, The heating element is located inside the switching mechanism 102, and the heating element can be in close contact with the desiccant; the controller 201 is further configured to control the heating element to perform heating after sending a first switching instruction to the switching mechanism 102.

It can be understood that after the controller 201 sends the first switching instruction to the switching mechanism 102, the switching mechanism 102 switches the desiccant in the first desiccant container to the second communication state. At this time, the The desiccant is in contact with the air outside the drying chamber 101, and the heating element is used to heat the desiccant, which can accelerate the speed of releasing the moisture absorbed in the desiccant.

The following describes the specific implementation of the dehumidification device of the present invention through several application examples.

Application Example 1

The switching mechanism 102 in the above dehumidification device may include a first rotating member and a first motor.

FIG. 3A is a schematic structural diagram of a first rotating member according to Embodiment 1 of the present invention, and FIG. 3B is a schematic cross-sectional view of a first rotating member according to Embodiment 1 of the present invention. As shown in FIGS. 3A and 3B, the first rotating member includes The first desiccant container 301, the second desiccant container 302, and the isolating element, wherein the first desiccant container 301 and the second desiccant container 302 are configured to store the desiccant 304 described above, and the isolating element is configured to isolate the first drying agent The agent container 301 and the second desiccant container 302. Further, a leak-proof soft glue 303 may be provided around the isolation element. Here, in FIG. 3A, the desiccant in the first desiccant container 301 and the second desiccant container 302 is omitted.

Here, the desiccant of the first desiccant container 301 and the desiccant 304 of the second desiccant container 302 are in different communication states at any time; that is, when the desiccant 304 of the first desiccant container 301 is in the first communication In the state, the desiccant 304 of the second desiccant container 302 is in the second communication state; when the desiccant 304 of the first desiccant container 301 is in the second communication state, the desiccant 304 of the second desiccant container 302 is in the first communication state. Connected state.

In the embodiment of the present invention, the shapes of the first desiccant container 301 and the second desiccant container 302 are not limited. For example, referring to FIGS. 3A and 3B, the first desiccant container 301 and the second desiccant container 302 are both cylindrical. Half of the shape structure, the first desiccant container 301 and the second desiccant container 302 together form a cylindrical structure.

It can be seen that, because the isolation element can isolate the first desiccant container 301 and the second desiccant container 302, in this way, the desiccant 304 of the first desiccant container 301 and the desiccant 304 of the second desiccant container 302 can be prevented from mixing. ; Optionally, the horizontal dimension of the isolation element and the leak-proof soft glue 303 (that is, the direction perpendicular to the communication direction inside the drying chamber 101 and the outside of the drying chamber 101) and the size of the connection between the inside of the drying chamber 101 and the outside of the drying chamber 101 The horizontal dimensions are closely matched, so that the horizontal isolation element 303 can completely isolate the air outside the drying chamber 101 and the air inside the drying chamber 101.

It should be noted that neither the first desiccant container 301 nor the second desiccant container 302 is a completely closed structure. In one example, at least one side of the first desiccant container 301 is provided with a vent hole, and the second desiccant container 302 is provided. At least one side is provided with a vent hole (not shown in FIGS. 3A and 3B). In this way, the air of the first desiccant container 301 and the second desiccant container 302 can be exchanged with the outside air; in another example, The shells of the first desiccant container 301 and the second desiccant container 302 have a mesh structure (the mesh structure is omitted in FIG. 3A). In this way, the first desiccant container 301 and the second desiccant container 302 can be made. Air exchanges with the outside air; it should be noted that when the shells of the first desiccant container 301 and the second desiccant container 302 have a mesh structure, and the drying of the first desiccant container 301 and the second desiccant container 302 is dry When the shape of the desiccant 304 is granular, the particle size of the desiccant 304 of the first desiccant container 301 and the second desiccant container 302 needs to be larger than the mesh size of the above mesh structure, so as to ensure the first desiccant container 301 The second desiccant desiccant container 302 not 304 corresponding desiccant container from leaking.

At this time, the first desiccant The desiccant 304 of the container 301 is in the first communicating state, and the desiccant 304 of the second desiccant container 302 is in the second communicating state. When the first desiccant container 301 is outside the drying chamber 101, the second desiccant container 302 is in the drying chamber. In 101, at this time, the desiccant 304 of the first desiccant container 301 is in the second communication state, and the desiccant 304 of the second desiccant container 302 is in the first communication state.

With reference to FIG. 3A and FIG. 3B, the rotation method of the first rotating member may be: rotating 180 degrees around the central axis of the cylindrical structure formed by the first desiccant container 301 and the second desiccant container 302, so that if the first drying The desiccant of the desiccant container 301 is initially in a first communicating state, and the desiccant 304 of the second desiccant container 302 is initially in a second communicating state. By rotating the first rotating member, the first desiccant container 301 can be dried. The desiccant 304 is in the second communicating state, and the desiccant 304 of the second desiccant container 302 is in the first communicating state; otherwise, if the desiccant 304 of the first desiccant container 301 is initially in the second communicating state, the second desiccant container The desiccant 304 of 302 is initially in the first communicating state, and by rotating the first rotating member, the desiccant 304 of the first desiccant container 301 can be in the first communicating state, and the desiccant 304 of the second desiccant container 302 is in the first communicating state.

Here, the implementation manner of the controller 201 sending the second switching instruction to the first motor is the same as the implementation manner of the controller 201 sending the second switching instruction to the switching mechanism described above.

In one embodiment, the dehumidifying device further includes: a second humidity sensor in contact with the desiccant 304 in the second desiccant container 302, and a data receiving end of the controller is connected to a data output end of the second humidity sensor;

When the desiccant 304 in the first desiccant container 301 is in the first communication state, if the humidity data collected by the first humidity sensor is greater than or equal to the first humidity A threshold value, or if the humidity data collected by the second humidity sensor is less than or equal to the second humidity threshold value, a first switching instruction is sent to the switching mechanism; when the desiccant 304 in the first desiccant container 301 is in the second connected state, If the humidity data collected by the first humidity sensor is less than or equal to the second humidity threshold, or the humidity data collected by the first humidity sensor is greater than or equal to the first humidity threshold, a second switching instruction is sent to the switching mechanism.

It can be seen that, in Application Example 1, when the desiccant of one desiccant container of the first desiccant container 301 and the second desiccant container 302 is in the first communication state, the first desiccant container 301 and the second desiccant are dried. The desiccant of the other desiccant container of the agent container 302 is in the second communication state. When the desiccant in the first communication state absorbs the moisture in the drying chamber 101, the desiccant in the second communication state can release the adsorbed moisture. Into the air; after the first rotating part rotates, the desiccant in the first connected state can initially release the adsorbed moisture into the air, and the desiccant in the second connected state can initially adsorb the moisture in the drying chamber; Through the rotation of the first rotating member, the effect of the desiccant in the first desiccant container 301 and the desiccant container 302 in turn adsorbing moisture can be achieved.

Application Example 2

4 is a schematic longitudinal sectional view of a switching mechanism according to the second embodiment of the present invention; FIG. 5 is a perspective schematic view of the switching mechanism according to the second embodiment of the present invention; and FIG. 6 is another perspective of the switching mechanism according to the second embodiment of the present invention. 4 to 6, the switching mechanism 102 in the dehumidifying device may include a substrate 401 and a second rotating member 402 disposed on the substrate. The substrate 102 is in close contact with the second rotating member 402. The first desiccant A container (not shown in FIGS. 4 to 7) is located in the second rotating member 402.

FIG. 7 is a schematic structural diagram of a substrate according to the second embodiment of the present invention. Referring to FIG. 7, the substrate 401 is provided with a first air inlet 701 and a first air outlet 702 of a first air duct, and a second air inlet 703 and Air outlet 704. Here, the first air duct is a passage for the airflow outside the drying chamber 101 to flow out of the drying chamber 101 after passing through the desiccant in the first desiccant container, and the second air duct is the airflow inside the drying chamber 101 after the first drying. The desiccant in the agent container flows to the channel in the drying chamber 101;

That is, referring to FIGS. 4 and 5, when the first air duct is completely connected, the airflow outside the drying chamber 101 can enter the second rotating member 402 through the first air inlet 701 of the first air duct, and the airflow flows through the first The desiccant in the desiccant container can flow out through the first air outlet 702 having the first air duct. In this way, when the desiccant in the first desiccant container is in the second communication state, it can pass through the first air duct and the drying chamber. Outside 101 quickly releases the adsorbed moisture.

6 and 7, when the second air duct is completely connected, the airflow in the drying chamber 101 can enter the second rotating member 402 through the air inlet 703 of the second air duct, and the airflow flows through the drying in the first desiccant container. The agent can flow out through the air outlet 704 with the second air duct. In this way, when the desiccant in the first desiccant container is in the first communication state, the moisture in the drying chamber 101 can be quickly absorbed through the first air duct.

Here, for the first air duct and the second air duct, multiple air inlets and multiple air outlets may be provided. For example, referring to FIGS. 4 to 7, the substrate 401 is provided with the second air inlet 705 of the first air duct. And the second air outlet 706, here, the airflow channel between the second air inlet 705 of the first air duct and the first air inlet 701 is completely connected at any time, and the second air outlet 706 of the first air duct and The airflow passage between the first air outlets 702 is in a fully connected state at any time.

At any time, the cooperation of the second rotating member 402 through the substrate 401 can block the first air inlet 701 and the first air outlet 702 of the first air duct, or the air inlet 703 and the air outlet 704 of the second air duct. For example, the center connection direction of the first air inlet 701 and the first air outlet 702 is perpendicular to the center connection direction of the second air inlet 703 and the air outlet 704. When the substrate 401 is in a horizontal position, In the example, the front and rear sides of the second rotating member 402 are respectively provided with two shielding portions, and the left and right sides of the second rotating member 402 are not provided with shielding portions. In another example, the second rotating member 402 There are two shielding parts on the left and right sides, and there are no shielding parts on the front and rear sides of the second rotating member 402. These two shielding parts are in close contact with the substrate 401. One of the two shielding parts When one part blocks the first air inlet 701, the other block part covers the first air outlet 702; when one block part blocks the air inlet 703 of the second air duct, the other block part blocks the air outlet 704 of the second air duct.

It can be understood that when the second rotating member 402 covers the first air inlet 701 and the first air outlet 702 of the first air duct, the first air duct is in a disconnected state, and the desiccant in the first desiccant container cannot communicate with the desiccant. When the air outside the drying chamber 101 comes into contact, the moisture in the drying chamber 101 can be adsorbed only through the second air duct, that is, the desiccant in the first desiccant container is in the first communication state; when the second rotating member 402 blocks When the air inlet 703 and the air outlet 704 of the second air duct are in a disconnected state, the desiccant in the first desiccant container cannot contact the air in the drying chamber 101, and can only pass through the first air duct. The outside of the drying chamber 101 releases the adsorbed moisture, that is, the desiccant is in a second communication state.

In practical applications, the switching mechanism 102 further includes a second motor, and the controller 201 is specifically configured to send a first switching command to the second motor; the second motor is configured to drive the second motor after receiving the first switching command The rotating member 402 rotates, so that the desiccant of the first desiccant container communicates with the air inlet 701 and the air outlet 702 of the first air duct, and the second rotating member 402 covers the air inlet of the second air duct. 703 and air outlet 704; specifically, the second rotating member 402 can rotate around its own central axis, so that the two shielding portions of the second rotating member 402 change the contact position with the substrate 401, where the central axis and the substrate 401 The plane is vertical.

The second motor is a motor that controls the rotation angle according to the received control signal. The second motor cooperates with the second rotating member 402 to drive the second rotating member 402 to rotate a specific angle about its own central axis. Here, the specific angle and the first The relative positions of the air inlet 701, the first air outlet 702, the second air inlet 703, and the air outlet 704 are related. For example, when the second rotating member 402 covers the first air inlet 701 and the first air outlet 702, The second motor sends a first control signal, and the second motor controls the second rotating member 402 to rotate 90 degrees according to the first control signal, so that the shielding portion of the second rotating member 402 covers the air inlet 703 and the air outlet 704 of the second air duct. ; When the second rotating member 402 covers the air inlet 703 and the air outlet 704 of the second air duct, it sends a second control signal to the second motor, and the second motor controls the second rotating member 402 to rotate 90 degrees according to the second control signal , The shielding portion of the second rotating member 402 covers the first air inlet 701 and the first air outlet 702.

When the desiccant is in the first communication state initially, the second rotating member 402 covers the first air inlet 701 and the first air outlet 702 of the first air passage through two shielding portions. At this time, by rotating the second rotating member, When the shielding portion of the second rotating member 402 shields the air inlet 703 and the air outlet 704 of the second air duct, the desiccant in the first desiccant container can only release the adsorbed moisture to the outside of the drying chamber 101 through the first air duct. That is, the desiccant in the first desiccant container is switched from the first communication state to the second communication state.

Further, the controller 201 is further configured to send a second switching instruction to the second motor after sending the first switching instruction to the second motor;

The second motor is further configured to drive the second rotating member 402 to rotate after receiving the second switching instruction, so that the desiccant of the first desiccant container communicates with the air inlet 703 and the air outlet of the second air duct. 704, and make the second rotating member 402 block the first air inlet 701 and the first air outlet 702 of the first air duct.

Here, the implementation manner in which the controller 201 sends the second switching instruction to the second motor is the same as the implementation manner in which the controller 201 sends the second switching instruction to the switching mechanism, which is not described herein again.

It can be seen that when the desiccant is initially in the second communication state, the second rotating member 402 covers the air inlet 703 and the air outlet 704 of the second air passage through two shielding portions. At this time, by rotating the second rotating member, If the shielding part of the second rotating member 402 covers the first air inlet 701 and the first air outlet 702, the desiccant in the first desiccant container can only absorb the moisture in the drying chamber 101 through the second air duct, that is, to achieve In this way, the desiccant in the first desiccant container is switched from the second communication state to the first communication state.

In summary, the first and second air ducts can be switched by the rotation of the second rotating member 402. When the first air duct is connected, the first desiccant container can be taken away from the drying chamber 101 by the wind. Moisture absorbed by the desiccant; when the second air duct is connected, the moisture can be absorbed from the drying chamber 101 to achieve a dehumidifying effect on the drying chamber 101; and the first air duct and the second air duct cannot be connected at the same time, that is, Said that through the setting of double air ducts, it is possible to prevent the dry outdoor air from interfering with the dry indoor air.

Further, referring to FIG. 4, a second heating element 403 for heating the desiccant in the first desiccant container is provided on both the top and the bottom in the second rotating member 402, and the controller 201 is further configured to send to the second motor After the first switching instruction, the second heating element 403 is controlled to perform heating.

It can be understood that when the first air duct is connected, when the second rotating member receives the airflow outside the drying chamber 101 through the first air duct, if the temperature in the second rotating member is low, the airflow outside the drying chamber 101 Condensation may occur during the pre-cooling of water, which is not conducive to the rapid release of water in the desiccant in the first desiccant container. In view of this problem, in Embodiment 2 of the present invention, due to the A second heating element for heating the desiccant in the first desiccant container is provided on both the top and the bottom. In this way, the temperature of the inner wall of the second rotating member can be quickly raised to avoid condensation in the second rotating member.

Further, a fan may be provided inside the second rotating member. When the fan inside the second rotating member is operated, the air velocity of the first air duct or the second air duct may be accelerated, thereby improving the efficiency of the desiccant to absorb moisture and the desiccant. Efficiency of releasing moisture.

When the switch member 802 cuts off the contact channel between the desiccant in the first desiccant container and the air in the drying chamber 101, The contact between the desiccant in the first desiccant container and the air outside the drying chamber 101 can release the moisture in the desiccant in the first desiccant container to the air.
