Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as a method and apparatus for controlling a dehumidifier, a dehumidifier, and a storage medium. Background Technology

[0002] Currently, in daily life, dehumidifiers are used to maintain suitable air humidity in living environments and prevent excessive indoor dampness. The dehumidifier's fan draws indoor air into the machine, where it first passes through an evaporator that absorbs heat, causing water vapor to condense and thus dehumidify. Then, the air passes through a condenser that absorbs heat from the refrigerant before being released back into the room.

[0003] In related technologies, to improve the cooling efficiency of the condenser, a flow-guiding component is installed between the evaporator and condenser arranged side by side. By acquiring the dehumidification signal from the dehumidifier, a portion of the low-temperature condensate produced by the evaporator is sprayed onto the condenser through the flow-guiding component, thereby achieving water-cooling cooling of the condenser while the airflow passes through it.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, when cooling the condenser, the refrigerant inside releases a large amount of heat. Low-temperature condensate sprayed onto the condenser absorbs this heat and evaporates back into water vapor. At this point, when the air, cooled and dehumidified by the evaporator, flows through the condenser, the water vapor generated by the condenser mixes with the dehumidified air, causing the humidity of the dehumidified air to increase again. This reduces dehumidification efficiency and user comfort.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method and apparatus for controlling a dehumidifier, a dehumidifier, and a storage medium to improve the dehumidification efficiency of the dehumidifier.

[0009] In some embodiments, the dehumidifier includes an evaporator for cooling and dehumidifying air, a water tray for receiving condensate from the evaporator, a condenser, and a cooling water tank disposed below the condenser. The condensate in the water tray can be guided into the cooling water tank to form a water-cooling medium. The condenser includes a second condensing section and a first condensing section distributed vertically. The cooling water tank includes a bottom wall and a vertically retractable peripheral side wall. The peripheral side wall includes a fixed section and a retractable section. The fixed section and the bottom wall enclose a first cooling space, and the retractable section encloses a second cooling space. The first condensing section is disposed within the first cooling space, and the retractable section extends into the second cooling space.

[0010] In some embodiments, the dehumidifier further includes a water storage tank, and a water supply pipe is connected between the water storage tank and the cooling water tank.

[0011] In some embodiments, when the indoor temperature is greater than or equal to a preset temperature, adjusting the telescopic section to switch to the extended state includes: when the indoor temperature is greater than or equal to the preset temperature, obtaining the target outlet air temperature of the dehumidifier; determining the target extension height of the telescopic section based on the temperature difference between the indoor temperature and the target outlet air temperature; and adjusting the telescopic section to switch to the extended state based on the target extension height of the telescopic section.

[0012] In some embodiments, determining the target extension height of the telescopic section based on the difference between the indoor temperature and the target outlet air temperature includes: if the temperature difference between the indoor temperature and the target outlet air temperature is less than or equal to a preset temperature difference, then determining the target extension height of the telescopic section corresponding to the preset temperature difference based on the correspondence between the temperature difference and the height of the telescopic section; if the temperature difference between the indoor temperature and the target outlet air temperature is greater than the preset temperature difference, then determining the upper limit threshold of the height of the telescopic section as the target extension height of the telescopic section.

[0013] In some embodiments, determining the target extension height of the telescopic section corresponding to a preset temperature difference based on the correspondence between temperature difference and telescopic section height includes: obtaining a telescopic section height information table, wherein the telescopic section height information table stores the height of the telescopic section corresponding to each range of different temperature differences; if the temperature difference between the indoor temperature and the target air outlet temperature is less than the preset temperature difference, then obtaining a preset temperature difference range that matches the preset temperature difference and a preset extension height of the telescopic section that matches the preset temperature difference range from the telescopic section height information table, and determining the preset extension height of the telescopic section that matches the preset temperature difference range as the target extension height of the telescopic section.

[0014] In some embodiments, the dehumidifier further includes a water storage tank, and a water supply pipe is connected between the water storage tank and the cooling water tank. A water guiding drive device is provided on the water supply pipe. The method for controlling the dehumidifier further includes: when the telescopic section is extended to a target extension height, obtaining a second height difference between the peripheral sidewall and the water-cooling medium; when the second height difference between the peripheral sidewall and the water-cooling medium is less than or equal to a second preset height difference, controlling the water guiding drive device to open so as to output the water-cooling medium to the water storage tank.

[0015] In some embodiments, the method for controlling the dehumidifier further includes: obtaining a third height difference between the peripheral wall and the water-cooled medium when the water-guiding drive device is running for a second period of time; and controlling the water-guiding drive device to stop when the third height difference between the peripheral wall and the water-cooled medium is greater than or equal to a third preset height difference.

[0016] In some embodiments, the apparatus for controlling a dehumidifier includes a processor and a memory storing program instructions, characterized in that the processor is configured to execute the aforementioned method for controlling a dehumidifier when the program instructions are executed.

[0017] In some embodiments, the dehumidifier includes: an evaporator for cooling and dehumidifying air; a drip tray for receiving condensate from the evaporator; a condenser including a second condensing section and a first condensing section distributed vertically; a cooling water tank disposed below the condenser, wherein condensate in the drip tray can be guided to the cooling water tank to form a water-cooling medium, the cooling water tank including a bottom wall and a vertically retractable peripheral wall, the peripheral wall including a fixed section and a telescopic section, the fixed section and the bottom wall enclosing a first cooling space, the telescopic section enclosing a second cooling space, wherein the first condensing section is disposed in the first cooling space, and when the telescopic section is extended, part or all of the second condensing section is located in the second cooling space; and, as described above, a device for controlling the dehumidifier.

[0018] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned method for controlling a dehumidifier.

[0019] The method and apparatus for controlling a dehumidifier, the dehumidifier itself, and the storage medium provided in this disclosure can achieve the following technical effects:

[0020] By obtaining the indoor temperature, the switching scheme of the expansion and contraction sections of the perimeter wall can be determined, thereby enabling the determination of different cooling schemes for the second condensing section. This allows for the adjustment of different cooling methods for the condenser, thereby improving dehumidification efficiency. In this scheme, when the indoor temperature is low, the condensate collected in the drip tray is used as the water-cooling medium for the first condensing section, achieving water-cooling cooling. At this time, the expansion and contraction sections switch to the contracted state, and the air cooled and dehumidified by the evaporator can flow through the second condensing section for air-cooling cooling. This scheme achieves a combined water-cooling and air-cooling cooling method for the condenser, ensuring the cooling effect of the condenser while improving dehumidification efficiency. In this solution, when the indoor temperature is high, the condensate collected in the drip tray serves as the cooling medium for both the first and second condensing sections, achieving partial or complete water-cooling of the condenser. At this time, the telescopic section switches to its extended state, partially or completely enclosing the second condensing section within the second cooling space. Thus, when the second condensing section is partially immersed in the cooling medium, a combined water-cooling and air-cooling method is achieved for the condenser; alternatively, when the second condensing section is completely immersed, a total water-cooling method is achieved for the condenser. This improves dehumidification efficiency while maintaining the condenser's cooling effect. This solution can improve air dehumidification efficiency while ensuring the condenser's cooling effect, meeting users' energy-saving needs for dehumidifiers.

[0040] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides a dehumidifier, including a housing 100, an evaporator 200, a drip tray 210, a condenser 300, and a cooling water tank 400. The housing 100 internally defines an air cavity 101. The housing 100 includes a vertically extending first sidewall 110, on which an air inlet 510 connecting to the air cavity 101 is formed. The evaporator 200 is disposed in the air cavity 101 and arranged near the air inlet 510. The drip tray 210 is correspondingly disposed below the evaporator 200 and connected to the inner wall of the housing 100, for receiving condensate generated by the evaporator 200. The condenser 300 is disposed within the air cavity 101 and includes a first condensing section 310 and a second condensing section 320 that are interconnected. The cooling water tank 400 is disposed below the condenser 300 and communicates with the drip tray 210. The cooling water tank 400 includes a bottom wall 410 and a peripheral side wall 420 surrounding the condenser 300. The peripheral side wall 420 includes a fixed section 421 and a telescopic section 422. The fixed section 421 and the bottom wall 410 enclose a first cooling space, and the telescopic section 422 encloses a second cooling space that communicates with the first cooling space. The first condensing section 310 is immersed in the condensate within the first cooling space. When the telescopic section 422 is in its extended state, at least a portion of the second condensing section 320 is immersed in the condensate within the second cooling space.

[0041] The casing 100 defines an air cavity 101, within which an evaporator 200 and a condenser 300 are arranged. The evaporator 200 and condenser 300 are connected via refrigerant piping. The liquid refrigerant needs to evaporate and absorb heat in the evaporator 200, while the gaseous refrigerant needs to condense and release heat in the condenser. Thus, humid indoor air flows into the air cavity 101 through the air inlet 510, first passing through the evaporator 200, where it exchanges heat with the refrigerant, thereby lowering the air temperature. This results in condensation on the evaporator 200, achieving dehumidification of the air.

[0042] A drip tray 210, located below the evaporator 200, collects the condensate generated therefrom and delivers it to the cooling water tank 400. Optionally, the drip tray 210 is fixedly connected to the inner wall of the casing 100 to improve its stability.

[0043] The peripheral wall 420 of the cooling water tank 400 extends circumferentially along the condenser 300 to surround the condenser 300. The peripheral wall 420 includes a fixed section 421 and a telescopic section 422. The height of the fixed section 421 is at least higher than the bottom of the condenser 300, defining a first cooling space between it and the bottom wall 410. The first condensing section 310 of the condenser 300 is located within the first cooling space. Since the height of the fixed section 421 cannot be changed, the condensate collected by the drip tray 210 can always fill the first cooling space, achieving water-cooled cooling of the first condensing section 310. Due to the low temperature of the condensate, the cooling efficiency of the first condensing section 310 can be improved. Meanwhile, the second condensing section 320 achieves air-cooled cooling by exchanging heat with the dehumidified air. Meanwhile, when the condenser 300 is partially cooled by water, the contact area between the air flowing through the evaporator 200 and the condenser 300 can be reduced, thereby lowering the temperature of the airflow flowing through the condenser 300 and improving the comfort of the dehumidifier's exhaust air.

[0044] Furthermore, the telescopic section 422 of the peripheral sidewall 420 has an extended state and a retracted state. In the extended state, the telescopic section 422 extends upward, which can partially or completely cover the second condensing section 320. The telescopic section 422 encloses a second cooling space that communicates with the first cooling space. The height of the condensate in the cooling water tank 400 can be matched with the height of the peripheral sidewall 420. When the telescopic section 422 partially covers the second condensing section 320, the first condensing section 310 and part of the second condensing section 320 are cooled by water, and the part of the second condensing section 320 is cooled by air through heat exchange with the dehumidified air, thus further improving the cooling effect on the condenser 300. When the telescopic section 422 completely covers the second condensing section 320, both the first condensing section 310 and the second condensing section 320 are cooled by water, which can further improve the cooling effect on the condenser 300.

[0045] In addition, this allows for the reuse of condensate produced by the evaporator 200, thereby improving energy efficiency and reducing energy consumption.

[0046] When using the dehumidifier provided in this embodiment, air flows into the air cavity through the air inlet when dehumidifying high-temperature and high-humidity air is required. After exchanging heat with the evaporator, the air flows to the condenser. The refrigerant in the evaporator absorbs heat from the air, causing water vapor in the air to condense. The condensate drips down the evaporator into a drip tray. Since the drip tray is connected to the cooling water tank, the condensate first accumulates in the first cooling space of the cooling water tank, thereby achieving water cooling of the first condensing section of the condenser. When the humidity and / or temperature of the air is high, by controlling the extension section of the cooling water tank to switch to the extended state, the height of the second cooling space can be increased. The height of the cooling water tank matches the height of the condensate inside, so that the second condensing section is partially or completely immersed in the condensate, thereby achieving partial or complete water cooling of the second condensing section. In this way, by using the low-temperature condensate generated by the evaporator to cool the first condensing section, part or all of the second condensing section, the cooling effect of the condenser can be improved. At the same time, the temperature of the air after passing through the condenser can be reduced, that is, the outlet air temperature of the dehumidifier can be reduced, thereby improving the comfort of the air outlet of the dehumidifier.

[0047] In addition, using the condensate produced by the evaporator to partially or completely cool the condenser can improve energy efficiency and avoid wasting condensate.

[0048] Optionally, combined Figure 2 , Figure 3 and Figure 5 As shown, the bottom plate or side plate of the water receiving tray 210 is provided with a drain outlet, and the bottom wall 410 or the fixed section 421 of the cooling water tank 400 is provided with a water inlet. The dehumidifier also includes a first water guide pipe 610. The first end of the first water guide pipe 610 is connected to the drain outlet, and the second end is connected to the water inlet. The height of the drain outlet is higher than the height of the water inlet.

[0049] The condensate in the water collection tray 210 can be transported to the cooling water tank 400 through the first water guide pipe 610. Optionally, the water collection tray 210 is made of plastic to prevent it from being corroded by condensate. Optionally, the first water guide pipe 610 is also made of plastic.

[0050] Optionally, the height of the water inlet is lower than the height of the bottom of the first condensing section 310 of the condenser 300, so as to avoid the impact or scouring of the condenser 300 by the condensate and to avoid damage to the condenser 300.

[0051] Optionally, the height of the drain outlet is higher than the height of the inlet. In this way, the condensate can flow naturally into the cooling water tank 400 under the action of gravity.

[0052] Optionally, a one-way valve is provided on the first water guide pipe 610. The one-way valve is open from the first end of the first water guide pipe 610 to the second end.

[0053] Optionally, a filter screen is installed inside the cooling water tank 400, positioned between the bottom of the first condensing section 310 and the water inlet. This filter screen purifies the condensate, preventing dust and other impurities from adhering to the side wall of the condenser 300, thus ensuring efficient heat exchange between the condensate and the condenser 300. Furthermore, filter screens are not required at the drain and water inlet, preventing blockages that could cause condensate to flow into the cooling water tank 400 due to filter clogging.

[0054] Optionally, combined Figure 5 As shown, the bottom plate of the water receiving tray 210 has a downwardly concave arc-shaped section, and a drain outlet is provided at the lowest point of the arc-shaped section.

[0055] By designing the bottom plate of the water receiving tray 210 with a downwardly concave arc-shaped section, it is beneficial for condensate to collect at the arc-shaped section. Furthermore, a drain outlet is provided at the lowest point of the arc-shaped section to facilitate the discharge of condensate.

[0056] Optionally, the dehumidifier also includes a partition plate 140, a water storage tank 150, and a second water guide pipe 620. The partition plate 140 is located below the cooling water tank 400 and is fixedly connected to the water receiving tray 210 and to the inner wall of the casing 100. The partition plate 140 and the water receiving tray 210 cooperate to divide the internal space of the casing 100 into an upper and lower arranged air chamber 101 and a compressor chamber 102. The water storage tank 150 is located in the compressor chamber 102. The first end of the second water guide pipe 620 is connected to the cooling water tank 400, and the second end is connected to the water storage tank 150.

[0057] The partition plate 140 and the water tray 210 work together to divide the internal space of the casing 100 into an upper and lower air chamber 101 and a compressor chamber 102. The compressor of the dehumidifier is located in the compressor chamber 102 to prevent the heat generated by the compressor from being dissipated into the air chamber 101.

[0058] Optionally, a water storage tank 150 is also provided inside the compressor cavity 102, and the water storage tank 150 is connected to the cooling water tank 400 through a second water guide pipe 620. In this way, the water storage tank 150 can be used to store excess condensate in the cooling water tank 400. When the condensate in the cooling water tank 400 approaches the top of the peripheral wall 420, if the evaporator continues to produce condensate, the condensate will overflow from the cooling water tank 400. At this time, condensate can be poured into the water storage tank 150 through the second water guide pipe 620 to improve the safety of the dehumidifier operation.

[0059] Optionally, the dehumidifier also includes a water pump 621. The water pump 621 is disposed in the second water pipe 620 and is used to open or close the second water pipe 620.

[0060] When the water pump 621 is running, the second water pipe 620 can be opened to draw condensate from the cooling water tank 400 and transport it to the storage tank 150 through the second water pipe 620. When the water pump 621 stops running, the second water pipe 620 can be cut off to allow condensate to accumulate in the cooling water tank 400, thus ensuring the cooling effect on the condenser 300.

[0061] Optionally, the cooling water tank 400 also includes at least two electrically operated telescopic rods, respectively disposed on opposite sides of the condenser 300. The first end of each electric telescopic rod is fixed to the partition plate 140, and the second end is fixedly connected to the top end of the telescopic section 422.

[0062] Thus, when the electric telescopic rod moves, it can move the top of the telescopic section 422, which is the top of the peripheral wall 420 of the cooling water tank 400, causing the top of the peripheral wall 420 to move away from the partition plate 140, thus extending the telescopic section 422 of the peripheral wall 420; or, it can move the top of the peripheral wall 420 towards the partition plate 140, thus retracting the telescopic section 422 of the peripheral wall 420. The electric telescopic rod facilitates the adjustment of the height of the peripheral wall 420 of the cooling water tank 400, thereby changing the height of the second cooling space and achieving partial or complete water cooling of the second condensation section 320.

[0063] Optionally, the telescopic section 422 includes a pleated telescopic cylindrical wall. By setting the telescopic section 422 as a pleated telescopic cylindrical wall, the telescopic section 422 can be folded or extended neatly according to its own folds, which is conducive to adjusting the height of the peripheral wall 420 of the cooling water tank 400, thereby facilitating partial or complete water cooling of the second condensing section 320.

[0064] Optionally, the dehumidifier also includes a water level detection unit, a warning unit, and a control unit. The water level detection unit is located inside the water storage tank 150 and is used to detect the water level height inside the tank 150. The warning unit is located in the casing 100. The control unit is electrically connected to both the water level detection unit and the warning unit. The control unit is used to send an alarm signal to the warning unit when the water level is higher than a preset height, and to control the warning unit to issue a warning based on the alarm signal.

[0065] Optionally, the preset height is the maximum height to which the water tank 150 can hold water. When the water level is higher than the preset height, it indicates that the water tank 150 is full. The control unit sends an alarm signal to the notification unit, and the notification unit issues a warning based on the alarm signal, promptly notifying the user to empty the water tank 150. Optionally, the control unit is the control module of the dehumidifier. When the water level is higher than the preset height, the control unit is also used to stop the dehumidifier from operating to prevent further condensation.

[0066] Optionally, the notification unit includes an audible component that emits a full water warning sound upon receiving an alarm signal. This allows the user to know the dehumidifier's water tank is full even when not in the dehumidifier's location, enabling them to empty the water tank 150 promptly.

[0067] Optionally, the housing 100 further includes a second sidewall 120 and a third sidewall 130, the second sidewall 120 being arranged opposite to the first sidewall 110, and the third sidewall 130 being connected to the top of the first sidewall 110 and the second sidewall 120.

[0068] The dehumidifier also includes a first air outlet assembly and a second air outlet assembly. The first air outlet assembly includes a first air outlet 520 and a first guide fan 710, and the second air outlet assembly includes a second air outlet 530 and a second guide fan 720. The first air outlet 520 is located on the second side wall 120 and communicates with the air cavity 101. The first guide fan 710 is disposed between the first air outlet 520 and the condenser 300. The second air outlet 530 is located on the third side wall 130 and communicates with the air cavity 101. The second guide fan 720 is disposed between the second air outlet 530 and the condenser 300. When the telescopic section 422 is in the extended state, both the first air outlet 520 and the second air outlet 530 are open, and both the first guide fan 710 and the second guide fan 720 are running; alternatively, the first air outlet 520 is closed and the first guide fan 710 is stopped, while the second air outlet 530 is open and the second guide fan 720 is running. When the telescopic section 422 is in the retracted state, the first air outlet 520 is open and the first air guide fan 710 is running, the second air outlet 530 is closed and the second air guide fan 720 is stopped.

[0069] Optionally, the telescopic segment 422 may be partially or fully extended in its extended state.

[0070] When the telescopic section 422 extends, the first condensing section 310 and part of the second condensing section 320 are cooled by water, while another part of the second condensing section 320 exchanges heat with the dehumidified air to achieve air cooling.

[0071] In other words, when the telescopic section 422 is partially extended, the peripheral wall 420 of the cooling water tank 400 will block the dehumidified air from contacting the condenser 300. The second air outlet 530 and the second guide fan 720 allow some of the dehumidified air to be discharged through the second air outlet 530, and some of the dehumidified air to be discharged through the first air outlet 520, thus ensuring the dehumidifier's airflow.

[0072] At this time, the air temperature discharged through the second air outlet 530 is relatively low. When the indoor ambient temperature and / or humidity is high, it can improve the comfort of the dehumidifier's air outlet and improve the indoor temperature and humidity.

[0073] Optionally, when the telescopic section 422 is extended, the speed of the first guide fan 710 is higher than that of the second guide fan 720 to prevent all the dehumidified air from flowing out through the second air outlet 530. This allows some air to flow through the condenser 300 and towards the first air outlet 520, thereby allowing the second condensing section 320 exposed in the air cavity 101 to exchange heat with the flowing air, thus achieving cooling.

[0074] When the telescopic section 422 is fully extended, both the first condensing section 310 and the second condensing section 320 are water-cooled. At this time, the condenser 300 is completely blocked by the cooling water tank 400, and the dehumidified air cannot pass through the condenser 300. Therefore, the first air outlet 520 can be closed and the first guide fan 710 can be stopped, while the second air outlet 530 can be opened and the second guide fan 720 can be running. At this time, not only can the cooling efficiency of the condenser 300 be improved, but the low-temperature, low-humidity airflow flowing out through the second air outlet 530 can also improve the indoor temperature and humidity, thus enhancing comfort.

[0075] Optionally, when the telescopic section 422 is in the retracted state, the first condensing section 310 is immersed in the condensate water in the first cooling space to achieve water-cooling, while the second condensing section 320 is exposed to the air cavity 101 and needs to exchange heat with the dehumidified air to achieve air-cooling. At this time, the first air outlet 520 is opened and the first guide fan 710 is running, while the second air outlet 530 is closed and the second guide fan 720 is stopped. That is, all the dehumidified air flows through the second condensing section 320 to ensure the cooling effect on the condenser 300.

[0076] Combination Figure 6 As shown, this disclosure provides a method for controlling a dehumidifier, including:

[0077] S61, the dehumidifier obtains the indoor temperature.

[0078] S621, when the indoor temperature is lower than the preset temperature, the dehumidifier adjusts the telescopic section to switch to the retracted state so that the water-cooling medium is introduced into the first cooling space to cool the first condensation section.

[0079] S622, when the indoor temperature is greater than or equal to the preset temperature, the dehumidifier adjusts the telescopic section to the extended state, so that the water-cooling medium is introduced into the first cooling space to cool the first condensing section, and the cold water medium is introduced into the second cooling space to cool part or all of the second condensing section.

[0080] In this solution, the dehumidifier is equipped with a temperature sensor to detect the indoor temperature. Optionally, the temperature sensor is located at the air inlet of the dehumidifier to accurately obtain the temperature of the environment in which the dehumidifier is located, providing a precise data basis for determining the cooling method of the dehumidifier's condenser.

[0081] Furthermore, after the dehumidifier obtains the indoor temperature, it determines the adjustment scheme of the expansion and contraction state of the expansion and contraction section of the peripheral wall based on the indoor temperature. By adjusting the expansion and contraction section between the contracted and extended states, the first condensing section and part / all of the second condensing section can be immersed in the water-cooling medium, so as to improve the cooling efficiency of the condenser and the dehumidification efficiency at the same time.

[0082] When the dehumidifier starts running, the evaporator cools and dehumidifies the air flowing into it, producing condensate. The condensate is stored in a drip tray and flows to the cooling water tank, where it gradually accumulates in the first cooling space.

[0083] Furthermore, when the indoor temperature is lower than the preset temperature, the telescopic section is adjusted to switch to the retracted state, allowing the water-cooling medium to be introduced into the first cooling space to cool the first condensing section. The retracted state refers to retracting as much as possible to overlap with the top of the fixed section. For example, the preset temperature is 20°C. At this time, while the first condensing section is being cooled by the water-cooling medium, dehumidified air is simultaneously passing through the condenser to provide air cooling. This combination of water cooling and air cooling improves the condenser's cooling efficiency, thereby increasing dehumidification efficiency. The dehumidified air absorbs heat from the condenser, further evaporating moisture and improving dehumidification efficiency. Simultaneously, the low indoor temperature allows the high-temperature, low-humidity air formed after passing through the condenser to flow back into the room, minimizing discomfort for the user.

[0084] Furthermore, when the indoor temperature is greater than or equal to the preset temperature, the telescopic section is adjusted to the extended state to allow the water-cooling medium to be introduced into the first cooling space for water-cooling the first condensing section, and to allow the cold water medium to be introduced into the second cooling space for water-cooling part or all of the second condensing section. When the indoor temperature is greater than or equal to the preset temperature, it indicates a high indoor temperature, and at this time, both the indoor air humidity and temperature are high. Dehumidified air has a poor cooling effect on the condenser, and if the dehumidified air passes through the condenser to cool it, it will absorb a large amount of heat, resulting in a high outlet air temperature from the dehumidifier, which can easily cause discomfort to users when blown into the room. In this case, the telescopic section is controlled to switch to the extended state, so that the telescopic section encloses and forms a second cooling space, allowing the water-cooling medium to continue to accumulate in the second cooling space for water-cooling part or all of the second condensing section. The height of the water-cooling medium is adapted to the height of the surrounding sidewalls, that is, slightly lower than the height of the surrounding sidewalls.

[0085] When the telescopic section partially blocks the second condensing section, the condenser is cooled using a combination of water cooling and conventional cooling. This improves both dehumidification efficiency and condenser cooling efficiency, further enhancing dehumidification efficiency. When the telescopic section completely blocks the second condensing section, the condenser is cooled using water cooling. This improves the condenser's cooling effect, prevents increased humidity after dehumidification, further enhances dehumidification efficiency, lowers the dehumidifier's outlet air temperature, and improves user comfort.

[0086] The higher the extension height of the telescopic section, the higher the height of the water-cooled medium, and the lower the outlet air temperature of the dehumidifier.

[0087] In addition, this solution uses the condensate collected in the drip tray as the water cooling medium, which can utilize the condensation in the condensate to avoid energy waste and improve energy efficiency.

[0088] The method for controlling a dehumidifier provided in this disclosure allows for the determination of the switching scheme of the expansion and contraction sections of the peripheral wall based on the obtained indoor temperature. This enables the determination of different cooling schemes for the second condensing section, thereby adjusting the cooling method of the condenser and improving dehumidification efficiency. In this scheme, when the indoor temperature is low, the condensate collected in the drip tray is used as the water-cooling medium for the first condensing section, achieving water-cooling cooling. At this time, the expansion and contraction sections switch to the contracted state, and the air cooled and dehumidified by the evaporator can flow through the second condensing section for air-cooling cooling. This scheme achieves a combined water-cooling and air-cooling cooling method for the condenser, ensuring the cooling effect of the condenser while improving dehumidification efficiency. In this solution, when the indoor temperature is high, the condensate collected in the drip tray serves as the cooling medium for both the first and second condensing sections, achieving partial or complete water-cooling of the condenser. At this time, the telescopic section switches to its extended state, partially or completely enclosing the second condensing section within the second cooling space. Thus, when the second condensing section is partially immersed in the cooling medium, a combined water-cooling and air-cooling method is achieved for the condenser; alternatively, when the second condensing section is completely immersed, a total water-cooling method is achieved for the condenser. This improves dehumidification efficiency while maintaining the condenser's cooling effect. This solution can improve air dehumidification efficiency while ensuring the condenser's cooling effect, meeting users' energy-saving needs for dehumidifiers.

[0089] Optionally, the dehumidifier also includes a water storage tank, and a water supply pipe is connected between the water storage tank and the cooling water tank. The water supply pipe is equipped with a water guiding drive device, wherein the water supply pipe is a second water guiding pipe 620 and the water guiding drive device is a water pump 621.

[0090] Combination Figure 7 As shown in the embodiments of this disclosure, another method for controlling a dehumidifier is provided, including:

[0091] S71, a dehumidifier that obtains indoor temperature.

[0092] S72, when the indoor temperature is lower than the preset temperature, the dehumidifier adjusts the telescopic section to switch to the retracted state so that the water-cooling medium is introduced into the first cooling space to cool the first condensation section.

[0093] S73, the dehumidifier obtains the first height difference between the fixed section and the water-cooled medium after the dehumidifier has been running for a first preset time.

[0094] S74, when the first height difference is less than or equal to the first preset height difference, the dehumidifier controls the water guiding drive device to open so as to output water cooling medium to the water storage tank.

[0095] In this scheme, when the dehumidifier starts running for the first time, the indoor air humidity is high, so the rate of condensation is relatively fast during the initial operation phase. By obtaining the first height difference between the fixed section and the water-cooled medium within a first preset time period, it can be determined whether the water-cooled medium fills the first cooling space.

[0096] Furthermore, if the first height difference is greater than the first preset height difference, it indicates that the cooling medium has not yet filled the first cooling space; if the first height difference is less than or equal to the first preset height difference, it indicates that the cooling medium has filled the first cooling space. Therefore, the water guiding drive device is activated to output the cooling medium to the water storage tank, preventing the cooling medium from overflowing from the cooling water tank, thereby preventing the cooling medium from corroding the components inside the dehumidifier and improving safety. For example, the range of the first preset height difference is 10mm to 20mm, and the first preset duration is 3 minutes.

[0097] In addition, since the dehumidified air flows through the second condensing section to cool it down, the water guide drive device is activated when the first height difference is less than or equal to the first preset height difference. This can prevent the dehumidified air from carrying water-cooling medium, thus ensuring the dehumidification efficiency of the dehumidifier.

[0098] Combination Figure 8 As shown in the embodiments of this disclosure, another method for controlling a dehumidifier is provided, including:

[0099] S81, obtains the indoor temperature.

[0100] S82 obtains the target air outlet temperature of the dehumidifier when the indoor temperature is greater than or equal to the preset temperature.

[0101] S83 determines the target extension height of the telescopic section based on the temperature difference between the indoor temperature and the target outlet air temperature.

[0102] S84, adjust the telescopic section to switch to the extended state according to the target extension height of the telescopic section.

[0103] In this solution, the target outlet air temperature of the dehumidifier can be obtained when the indoor temperature is greater than or equal to a preset temperature. This target outlet air temperature can be the user-set outlet air temperature of the dehumidifier. Further, after obtaining the target outlet air temperature, the dehumidifier determines the target extension height of the telescopic section, and then adjusts the telescopic section to switch to the extended state based on this target extension height. This solution allows for precise determination of the target height of the telescopic section based on different target outlet air temperatures, thereby enabling water cooling of the second condenser section at the corresponding height, improving the condenser's cooling efficiency, and ultimately increasing dehumidification efficiency and reducing the outlet air temperature.

[0104] In some embodiments, determining the target extension height of the telescopic section based on the difference between the indoor temperature and the target outlet air temperature includes: if the temperature difference between the indoor temperature and the target outlet air temperature is less than or equal to a preset temperature difference, then determining the target extension height of the telescopic section corresponding to the preset temperature difference based on the correspondence between the preset temperature difference and the height of the telescopic section; if the temperature difference between the indoor temperature and the target outlet air temperature is greater than the preset temperature difference, then determining the upper limit threshold of the height of the telescopic section as the target extension height of the telescopic section.

[0105] Optionally, the correspondence between preset temperature difference values ​​and telescopic section heights is pre-stored in a database. After obtaining the temperature difference between the current indoor temperature and the target air outlet temperature, the corresponding preset temperature difference value and the corresponding telescopic section height can be retrieved from the database. For example, the preset temperature difference value is 6℃.

[0106] The greater the temperature difference between the target outlet air temperature and the indoor temperature, the lower the required outlet air temperature. Since a larger condenser surface area immersed in the water-cooled medium results in a lower outlet air temperature for the dehumidifier, a larger temperature difference necessitates a greater extension height of the telescopic section.

[0107] If the temperature difference between the indoor temperature and the target outlet air temperature is less than the preset temperature difference, the target extension height of the extension section corresponding to the preset temperature difference is further determined based on the correlation between the preset temperature difference and the extension section height. The temperature difference between the indoor temperature and the target outlet air temperature is positively correlated with the target extension height of the extension section. This solution improves the accuracy of determining the target extension height of the extension section under high temperature conditions, thus meeting the cooling requirements of the condenser and the dehumidification requirements of the dehumidifier.

[0108] If the temperature difference between the indoor temperature and the target outlet air temperature is greater than the preset temperature difference, it indicates that the indoor environment is at a high temperature. Therefore, the upper limit threshold of the extension section's height is determined as the target extension height of the extension section. With this solution, both the second and first condensing sections use water-cooling to reduce the outlet air temperature and improve comfort while ensuring dehumidification efficiency.

[0109] In some embodiments, determining the target extension height of the telescopic section corresponding to a preset temperature difference based on the correspondence between temperature difference and telescopic section height includes: obtaining a telescopic section height information table, wherein the telescopic section height information table stores the height of the telescopic section corresponding to each range of different temperature differences; if the temperature difference between the indoor temperature and the target air outlet temperature is less than the preset temperature difference, then obtaining a preset temperature difference range that matches the preset temperature difference and a preset extension height of the telescopic section that matches the preset temperature difference range from the telescopic section height information table, and determining the preset extension height of the telescopic section that matches the preset temperature difference range as the target extension height of the telescopic section.

[0110] Table 1-1 is a telescopic height information table, where L is the maximum extendable height of the telescopic section. Referring to Table 1-1, for example, if the difference between the indoor temperature and the target temperature is 2.6℃, then the preset temperature difference range matching 2.6℃ can be obtained from the telescopic height information table as (2,4]. In this case, 1 / 2L can be determined as the target extension height of the telescopic section.

[0111] Preset temperature difference range (°C) Preset extension height (mm) (0,2] 1 / 4L (2,4] 1 / 2L (4,6] 3 / 4L

[0112] Optionally, 1 / 4L is set to the first gear when the telescopic section is extended, 1 / 2L is set to the second gear when the telescopic section is extended, 3 / 4L is set to the third gear when the telescopic section is extended, and the telescopic section is set to the fourth gear when the telescopic section is extended.

[0113] For example, if the first target height of the water-cooled medium is determined to be the third setting, the dehumidifier can be adjusted step by step during the adjustment process. That is, first, the telescopic section is controlled to extend to the height corresponding to the first setting. When the water-cooled medium accumulates to a height suitable for the first setting, the telescopic section is adjusted to extend further to the height corresponding to the second setting. Further, when the water-cooled medium accumulates to a height suitable for the second setting, the telescopic section is adjusted again to the third setting, and then the water-cooled medium continues to accumulate. In this way, the target extension height of the telescopic section can be more accurately controlled step by step, ensuring precise control of the height of the water-cooled medium. This meets the user's dehumidification requirements while improving the cooling efficiency of the condenser and meeting the dehumidifier's low-temperature air output requirements.

[0114] In some embodiments, the dehumidifier further includes a water storage tank, and a water supply pipe is connected between the water storage tank and the cooling water tank. A water guiding drive device is provided on the water supply pipe, wherein the water supply pipe is a second water guide pipe 620, and the water guiding drive device is a water pump 621. The method for controlling the dehumidifier further includes: obtaining a second height difference between the peripheral sidewall and the water-cooled medium when the telescopic section is extended to a target extension height; and controlling the water guiding drive device to open when the second height difference between the peripheral sidewall and the water-cooled medium is less than or equal to a second preset height difference, so as to output the water-cooled medium to the water storage tank.

[0115] In this solution, when the telescopic section is extended to the target extension height, the operation or shutdown of the water-guiding drive device is determined by the second height difference between the peripheral wall and the water-cooling medium, ensuring that the height of the cold water medium matches that of the peripheral wall. If the second height difference between the peripheral wall and the water-cooling medium is less than or equal to a second preset height difference, it indicates that the water-cooling medium has filled the second cooling space. Therefore, the water-guiding drive device is activated to output the water-cooling medium to the water storage tank, preventing the water-cooling medium from overflowing from the cooling water tank and thus avoiding corrosion of the components inside the dehumidifier, thereby improving safety. For example, the range of the second preset height difference is 10mm to 15mm.

[0116] Optionally, when the telescopic section extends to the target extension height, a second height difference between the peripheral sidewall and the water-cooling medium is acquired at preset time intervals. If the second height difference is greater than a second preset height difference, the water-cooling medium needs to be continuously accumulated in the cooling water tank. Specifically, during the dehumidification phase of the dehumidifier operation, the rate of condensate formation is relatively fast, but decreases after a period of dehumidification. Therefore, the second height difference needs to be acquired multiple times before it becomes less than or equal to the second preset height difference.

[0117] Optionally, the method for controlling the dehumidifier further includes: obtaining a third height difference between the peripheral wall and the water-cooled medium when the water-guiding drive device is running for a second period of time; and controlling the water-guiding drive device to stop when the third height difference between the peripheral wall and the water-cooled medium is greater than or equal to a third preset height difference.

[0118] In this scheme, when the third height difference between the peripheral wall and the water-cooling medium is greater than or equal to a third preset height difference, the water-guiding drive device is stopped to cease outputting water-cooling medium into the storage tank. The water-cooling medium continues to accumulate in the cooling water tank to ensure cooling of the condenser. When the second height difference between the peripheral wall and the water-cooling medium again reaches a value less than or equal to a second preset height difference, the water-guiding drive device is restarted to output water-cooling medium into the storage tank. This cycle repeats to prevent water-cooling medium overflow. Optionally, the second duration is longer than the first duration.

[0119] Optionally, the first preset height difference is 1 / 6L.

[0120] Optionally, the dehumidifier further includes a first air outlet assembly and a second air outlet assembly. The first air outlet assembly is used to exhaust a portion of the dehumidified air that has passed through the condenser out of the dehumidifier, and the second air outlet assembly is used to exhaust another portion of the dehumidified air out of the dehumidifier.

[0121] Optionally, the method for controlling the dehumidifier further includes: when the telescopic section is switched to the retracted state, controlling both the first air outlet component and the second air outlet component to operate; when the telescopic section is switched to the extended state, and the temperature difference between the indoor temperature and the target air outlet temperature is less than or equal to a preset temperature difference, controlling both the first air outlet component and the second air outlet component to operate; when the telescopic section is switched to the extended state, and the temperature difference between the indoor temperature and the target air outlet temperature is greater than a preset temperature difference, controlling the first air outlet component to shut down and controlling the second air outlet component to operate.

[0122] In this design, when the temperature difference between the indoor temperature and the target outlet air temperature is less than or equal to a preset temperature difference, the extension height of the telescopic section is less than its upper limit threshold, and the extension state of the telescopic section is partially extended. Thus, when the telescopic section switches to the retracted state or the partially extended state, a portion of the condenser is surrounded by a peripheral wall, and this portion of the condenser undergoes water-cooling cooling through heat exchange with the water-cooling medium. This prevents all the dehumidified air from passing through the condenser at the same time; only a portion of the dehumidified air can pass through the part not surrounded by the peripheral wall to perform air-cooled heat exchange with this portion of the condenser. This portion of air, after heat exchange with the condenser, can be returned to the room through the first air outlet assembly, which includes a first air outlet and a first guide fan. At this time, the first air outlet is open, and the first guide fan is running.

[0123] Meanwhile, to ensure sufficient airflow from the dehumidifier, a second air outlet assembly is provided, comprising a second air outlet and a second guide fan. Since the second air outlet and the second guide fan are located above the condenser and at least partially between the evaporator and condenser, when the second air outlet is open and the second guide fan is running, some of the air dehumidified by the evaporator can be directly diverted and directed into the room, thus ensuring sufficient airflow from the dehumidifier.

[0124] With this solution, when the condenser switches to a retracted state or a partially extended state in the expansion and contraction section, both the first and second air outlet components are controlled to operate. This ensures the dehumidification efficiency of the dehumidifier while improving the cooling efficiency of the condenser, reducing the outlet air temperature, and guaranteeing the air volume of the dehumidifier.

[0125] Optionally, when the temperature difference between the indoor temperature and the target outlet air temperature is greater than a preset temperature difference, the extension height of the telescopic section equals its upper limit threshold, and it is in a fully extended state. At this time, the entire condenser is surrounded by a sidewall, and the condenser as a whole undergoes water cooling through heat exchange with the water-cooling medium. Therefore, the first outlet air assembly is shut down, and the second outlet air assembly is operated. With this scheme, when the telescopic section switches to the extended state, and the temperature difference between the indoor temperature and the target outlet air temperature is greater than a preset temperature difference, by controlling the first outlet air assembly to shut down and the second outlet air assembly to operate, the dehumidification efficiency of the dehumidifier is ensured while simultaneously improving the condenser's cooling efficiency, reducing the outlet air temperature, and maintaining the dehumidifier's airflow.

[0126] Optionally, when the telescopic section is switched to the retracted state, or when it is in the partially extended state and its extension height is less than or equal to 1 / 2L, the wind speed of the first guide fan is greater than the wind speed of the second guide fan to ensure the air volume of the second air outlet, so that most of the dehumidified air flows out through the second air outlet and the outlet temperature is reduced; when it is in the partially extended state and its extension height is greater than 1 / 2L, the wind speed of the first guide fan is less than the wind speed of the second guide fan to improve the cooling efficiency of the condenser, thereby improving the dehumidification efficiency, reducing the outlet temperature, and improving comfort.
