[0032] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] In the related art, the dehumidifier installed for the museum's cultural relics display cabinet cannot remove the water in the water tank when it is unattended. When the dehumidifier runs for a long time, it is easy to cause the water in the water tank to be overfilled, which in turn causes the water in the water tank to overflow.

[0034] In response to the technical problems existing in the related art, the embodiment of the present application provides a dehumidification device. In the dehumidification device provided by the embodiment of the present application, when the dehumidified water generated during the operation of the dehumidification component flows into the water tank, the dehumidification element provided in the water tank contacts the dehumidified water in the water tank, absorbs the dehumidified water in the water tank, and evaporates the absorbed dehumidified water to the external space of the space to be dehumidified. Therefore, by providing a dehumidification element and a water level sensor, when no one is on duty, the dehumidification element can be used to automatically drain the accumulated water in the water tank, and the water level sensor can be used to detect the accumulated water level to prevent the accumulated water in the water tank from overflowing, which is conducive to the long-term operation of the dehumidifier without causing the water in the water tank to be overfilled. It improves the problem in the related art that when the dehumidifier is unattended, the water in the water tank cannot be automatically drained, which easily causes the water in the water tank to overflow when the dehumidifier is running for a long time.

[0035] The following is combined with Figure 1-3 , the dehumidification equipment provided in the embodiment of the present application is exemplified.

[0036] Figure 1 This is a schematic diagram of the structure of a dehumidification device provided in an embodiment of the present application. Figure 1 As shown, the dehumidification equipment includes: a water tank 12 and a dehumidification component 11, the dehumidification component 11 is connected to the water tank 12 and the space to be dehumidified 13 respectively; the dehumidified water generated by the dehumidification component 11 in the space to be dehumidified 13 flows to the water tank 12; a dehumidification element 14 is arranged in the water tank 12, and part of the dehumidification element 14 is in contact with the accumulated water in the water tank 12; the dehumidification element 14 is used to absorb the accumulated water in the water tank 12 and evaporate it to the external space of the space to be dehumidified 13; a water level sensor 10 is fixed to the top of the water tank 12; the water level sensor 10 is used to detect the water level of the accumulated water in the water tank 12; wherein, when the water level of the accumulated water in the water tank 12 reaches the anti-overflow water level, the dehumidification component 11 stops working.

[0037] The space to be dehumidified 13 may be, for example, a space in a museum display cabinet, which is used to display cultural relics. The overflow-proof water level may be understood as a water level slightly lower than the full water level of the water tank.

[0038] One end of the dehumidification assembly 11 can be connected to the dehumidified space 13, for example, through a dehumidification pipe 111, and the other end of the dehumidification assembly 11 can be connected to the water tank 12, for example, through a drain pipe 112. Thus, the dehumidification assembly 11 can dehumidify the dehumidified space 13, and the dehumidified water generated during the dehumidification process can flow into the water tank 12.

[0039] Specifically, when the dehumidified water generated during the operation of the dehumidification component 11 flows into the water tank 12, some of the dehumidification elements 14 arranged in the water tank 12 come into contact with the dehumidified water in the water tank 12. Some of the dehumidification elements 14 can absorb the dehumidified water in the water tank 12 and evaporate the absorbed dehumidified water to the external space of the space to be dehumidified 13 through the part of the dehumidification elements 14 that are not in contact with the dehumidified water.

[0040] Since the service life of the dehumidification element 14 is limited, the performance of the dehumidification element 14 gradually decreases during use, which may cause the dehumidification amount of the dehumidification element 14 to be less than the dehumidification amount generated by the dehumidification component 11, causing the accumulated water in the water tank 12 to reach the full water level, thereby causing the accumulated water in the water tank 12 to overflow.

[0041] Based on this, the embodiment of the present application is provided with a water level sensor 10, which uses the water level sensor to detect the water level in the water tank 12. When it is detected that the water in the water tank 12 reaches the overflow prevention level, the dehumidification component 11 can be controlled to stop working, for example, by the control unit 18 described below, thereby preventing the water in the water tank 12 from overflowing.

[0042] Therefore, the embodiment of the present application sets up a dehumidification element 14 and a water level sensor 10. In an unattended situation, the dehumidification element 14 can be used to automatically drain the accumulated water in the water tank 12. At the same time, the water level sensor 10 can be used to detect the water level to prevent the accumulated water in the water tank 12 from overflowing. This is conducive to the long-term operation of the dehumidifier without causing the water in the water tank 12 to be overfilled. It improves the problem in the related art that the water in the water tank 12 cannot be automatically drained, which easily causes the water in the water tank 12 to overflow when the dehumidifier runs for a long time.

[0043] Exemplarily, the moisture dissipating element 14 includes a moisture dissipating wet film. Specifically, the moisture dissipating wet film can be a plant fiber wet film, a high molecular polymer material wet film, an inorganic fiber wet film or a composite wet film.

[0044] Among them, plant fiber wet film is usually made of natural plant fibers such as wood pulp, cotton fiber, etc., which has good water absorption and air permeability and relatively low cost; polymer material wet film is formed by materials such as polypropylene and polyvinyl alcohol, which has strong water absorption and good durability; inorganic fiber wet film can be formed by glass fiber, which has good high temperature resistance and is suitable for some high temperature environments; composite wet film is composed of multiple materials, which can combine the advantages of various materials to improve the performance of the wet film, such as water absorption, corrosion resistance and service life.

[0045] The dehumidification device provided in an embodiment of the present application includes: a water tank and a dehumidification assembly, wherein the dehumidification assembly is respectively connected to the water tank and the space to be dehumidified; dehumidified water generated by the dehumidification assembly in the space to be dehumidified flows into the water tank; a moisture dissipation element disposed in the water tank, a portion of which contacts accumulated water in the water tank; the moisture dissipation element is configured to absorb accumulated water in the water tank and evaporate it to a space outside the space to be dehumidified; a water level sensor is fixed to the top of the water tank; the water level sensor is configured to detect the level of accumulated water in the water tank; wherein the dehumidification assembly stops operating when the accumulated water level in the water tank reaches an overflow prevention level. When dehumidified water generated during operation of the dehumidification assembly flows into the water tank, the moisture dissipation element disposed in the water tank contacts the dehumidified water in the water tank, absorbs the dehumidified water in the water tank, and evaporates the absorbed dehumidified water to a space outside the space to be dehumidified. In addition, a water level sensor is provided to detect the accumulated water level in the water tank. When the accumulated water in the water tank reaches the overflow prevention level, the dehumidification assembly stops operating, thereby preventing the accumulated water in the water tank from overflowing. Therefore, by setting up a dehumidification element and a water level sensor, in an unattended situation, the dehumidification element can be used to automatically drain the accumulated water in the water tank, and the water level sensor can be used to detect the accumulated water level to prevent the accumulated water in the water tank from overflowing. This is conducive to the long-term operation of the dehumidifier without causing the water in the water tank to be overfilled, and improves the problem in the related technology that the water in the water tank cannot be automatically drained, which easily causes the water in the water tank to overflow when the dehumidifier runs for a long time.

[0046] In some embodiments, as Figure 1 As shown, the dehumidification device further includes a fan assembly 010. The fan assembly 010 is arranged toward the dehumidification element 14, and generates a suction airflow to the dehumidification element 14 by blowing air outward, thereby accelerating the evaporation of water molecules in the dehumidification element 14 into the external space of the space to be dehumidified.

[0047] In some embodiments, as Figure 1 As shown, the water level sensor 10 includes a first probe 01 and a second probe 02 arranged in parallel; the first probe 01 and the second probe 02 are directed toward the bottom of the water tank 12; when the accumulated water level in the water tank 12 reaches a preset water level, the first probe 01 and the second probe 02 come into contact with the accumulated water in the water tank 12 to sense a water level signal.

[0048] Specifically, during the dehumidification process of the dehumidification component 11, when the accumulated water level in the water tank 12 gradually rises to a preset water level, the first probe 01 and the second probe 02 begin to contact the accumulated water in the water tank 12. When the first probe 01 and the second probe 02 begin to contact the accumulated water in the water tank 12, the medium between the first probe 01 and the second probe 02 is water, so the resistance value of the water between the two probes can be detected. This resistance value is used to determine the water level signal, and as the water level rises, the water level signal gradually increases. When the overflow prevention water level signal is obtained, it can be determined that the accumulated water level in the water tank 12 is about to reach the full water level of the water accumulation portion 21 described below. At this time, the dehumidification component 11 can be controlled to stop operation, thereby preventing the accumulated water in the water tank 12 from overflowing.

[0049] Related technologies for detecting water levels include float-type water level sensors, photoelectric level sensors, and capacitive level sensors. Contamination on the outer wall of photoelectric level sensors can cause detection failure, while contamination on float-type sensors can cause the float to stick and cause detection failure. Capacitive level sensors can also misdetect when humidity is too high.

[0050] Compared to related technologies, the water level sensor provided in the embodiments of the present application detects the water level by measuring the resistance of the water between two probes. The first probe 01 and the second probe 02 can be configured as miniature metal probes. Due to their small diameter and smooth, rounded surface, the miniature metal probes significantly reduce surface deposits when in contact with dehumidified water, improving the reliability of the metal probes and enabling reliable detection of the water level in the water tank 12. Therefore, the water level sensor provided in the embodiments of the present application effectively reduces the risk of overflowing the water tank 12 during the dehumidification process.

[0051] It should be noted that during the dehumidification process of the dehumidification component 11, when the accumulated water level in the water tank 12 does not reach the preset water level, the first probe 01 and the second probe 02 are not in contact with the accumulated water, and the water level sensor will not detect a water level signal.

[0052] In some embodiments, as Figure 1 As shown, the water level sensor 10 includes a sensor body 15 and a shell 16 , wherein the sensor body 15 is located in the shell 16 ; the first ends of the first probe 01 and the second probe 02 are both connected to the sensor body 15 , and the second ends of the first probe 01 and the second probe 02 are both extended through the shell 16 .

[0053] The sensor body 15 may include a detection circuit. The housing 16 may be provided to protect the sensor body 15 to prevent the sensor body 15 from being in a space with high humidity and causing adverse effects on the detection circuit.

[0054] Specifically, the first end, i.e., the upper end, of the first probe 01 and the second probe 02 may be connected to a connecting wire for connecting to the detection circuit in the sensor body 15, so this end is preferably arranged in the shell 16 for protection, while the second end, i.e., the lower end, of the first probe 01 and the second probe 02, which is not connected to the connecting wire, is exposed to the outside of the shell 16. When the accumulated water level in the water tank 12 gradually rises to a preset water level, the lower ends of the first probe 01 and the second probe 02 begin to contact the accumulated water in the water tank 12 for sensing water level signals.

[0055] In some embodiments, Figure 2 This is a structural block diagram of a dehumidification device provided in an embodiment of the present application. Figure 1 On the basis of Figure 2 As shown, the dehumidification device also includes: a control unit 18, which is electrically connected to the water level sensor 10 and the dehumidification component 11 respectively; the control unit 18 is used to control the working state of the dehumidification component 11 according to the water level signal detected by the water level sensor 10.

[0056] Specifically, during the dehumidification process of the dehumidification component 11, the water level sensor 10 can transmit the detected water level signal to the control unit 18. When the anti-overflow water level signal is detected, it can be determined that the accumulated water in the water tank 12 is about to overflow. At this time, the control unit 18 can control the dehumidification component 11 to stop working to prevent the accumulated water in the water tank 12 from overflowing.

[0057] During the dehumidification process controlled by the dehumidification component 11, the control unit 18 can simultaneously control the operation of the fan component 010. When the fan component 010 is in operation, the fan component 010 blows air outward to generate a suction airflow to the dehumidification element 14, thereby accelerating the evaporation of water molecules in the dehumidification element 14 into the space outside the dehumidification space.

[0058] In some embodiments, combined Figure 1 and Figure 2 The dehumidification device also includes a prompt unit 19, which is electrically connected to the control unit 18; the control unit 18 is used to control the prompt unit 19 to issue a prompt message according to the water level signal.

[0059] Specifically, the control unit 18 can control the prompt unit 19 to issue different prompt messages based on different water level signals. For example, the prompt message can be an alarm message. Depending on the water level in the water tank 12, the prompt unit 19 can be controlled to issue alarm messages of varying severity, allowing the user to determine whether the water level in the water tank 12 has reached the limit water level based on the alarm message.

[0060] In some embodiments, combined Figure 1 and Figure 2The dehumidification device further includes: a humidity sensor 20, which is electrically connected to the control unit 18; the control unit 18 is used to control the working state of the dehumidification component 11 according to the humidity of the space to be dehumidified 13.

[0061] The humidity sensor 20 is used to detect the humidity of the dehumidified space 13, thereby controlling the operating state of the dehumidification component 11 based on the humidity information of the dehumidified space 13. Specifically, when the humidity of the dehumidified space 13 is detected to be greater than the required humidity, the dehumidification component 11 is controlled to start operating and dehumidify the dehumidified space 13 to reduce the humidity of the dehumidified space 13 to the required humidity.

[0062] For example, the detection probe of the humidity sensor 20 can be extended into the dehumidified space 13 ( Figure 1 ), is used to detect the humidity of the space 13 to be dehumidified.

[0063] In some embodiments, as Figure 1 As shown, the water tank 12 further includes a water accumulation portion 21 and an opening 22 located above the water accumulation portion 21 . The opening 22 is formed at the intersection of the top and the side of the water tank 12 , and the moisture dissipating element 14 is placed in the water tank 12 through the opening 22 .

[0064] The water accumulation portion 21 is used to receive the dehumidified water generated by the dehumidification assembly 11. When the dehumidified water in the water accumulation portion 21 reaches a full water level, the accumulated water will overflow outward through the opening 22.

[0065] In some embodiments, as Figure 1 As shown, the moisture dissipating element 14 contacts the bottom of the water tank 12 ; a portion of the moisture dissipating element 14 is located in the water accumulation portion 21 .

[0066] The dehumidification element 14 can be divided into a first portion and a second portion. The first portion is located above the water accumulation portion 21, while the second portion is located within the water accumulation portion 21. Specifically, the second portion can contact the water in the water accumulation portion 21 to absorb the water. The water absorbed by the second portion can then diffuse into the first portion and evaporate into the outside space through the corresponding openings 22 in the first portion. Thus, the dehumidification element 14 can automatically drain the water in the water accumulation portion 21.

[0067] For example, a fixing component such as a metal slot may be provided at the bottom of the water tank 12 , and the moisture dissipating element 14 may be fixed by the metal slot.

[0068] The arrangement of the dehumidifying element 14 in contact with the bottom of the water tank 12 increases the contact area between the dehumidifying element 14 and the water in the water accumulation portion 21 , thereby facilitating the dehumidifying element 14 to automatically remove the water in the water accumulation portion 21 .

[0069] On the basis of the above embodiments, an embodiment of the present application further provides a control method for a dehumidification device, which can be applied to the dehumidification device described in the above embodiments. Figure 3 This is a flow chart of a control method for a moisture dissipation device provided in an embodiment of the present application. Figure 3 As shown, the control method includes the following steps:

[0070] S301: Obtain the water level in the water accumulation area.

[0071] S302: Based on the accumulated water level in the water accumulation part reaching the anti-overflow water level, the dehumidification component is controlled to stop working.

[0072] Specifically, if Figure 1 As shown, the water level sensor 10 can detect the water level signal in the water accumulation portion 21 to obtain the water level in the water accumulation portion 21. When the water level in the water accumulation portion 21 reaches the anti-overflow level, that is, when the water in the water accumulation portion 21 is about to overflow, the dehumidification component 11 can be controlled to stop working to prevent the water in the water accumulation portion 21 from being overfilled and overflowing.

[0073] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the concept of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be based on the appended claims.
