[0026] This embodiment provides a dehumidifier that cools the compressor by using condensed water in a cooling pipe coiled outside the compressor, which can effectively dissipate heat from the compressor, improve the working efficiency of the compressor and extend its service life. Figure 1 1 is a schematic diagram of the overall structure of a dehumidifier 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the overall structure of the dehumidifier 100 from another perspective. Figure 3 1 is a schematic diagram of the internal structure of a dehumidifier 100 according to an embodiment of the present invention. Figure 4 yes Figure 3 A schematic diagram of the internal structure of the dehumidifier 100 from another perspective. Figure 5 1 is a schematic structural diagram of a partition 124 of a dehumidifier 100 according to an embodiment of the present invention. Figure 6 FIG. 1 is a schematic diagram showing the connection between the water pump 135 and the compressor 129 of the dehumidifier 100 according to an embodiment of the present invention. Figures 1 to 6 As shown, the dehumidifier 100 of this embodiment may generally include: a casing 110 , a heat exchanger 120 , a water receiving tray 127 , a water pump 135 and a compressor 129 .

[0027] The interior of the housing 110 may define a cavity. The heat exchanger 120 may be disposed in the cavity and configured to condense moisture in the air entering the cavity into condensed water. A water receiving pan 127 may be disposed below the heat exchanger 120 and configured to receive the condensed water generated by the heat exchanger 120. In other words, after the heat exchanger 120 condenses moisture in the air into condensed water, the condensed water may first enter the water receiving pan 127. Ultimately, the condensed water may be discharged to the exterior of the dehumidifier 100, thereby achieving the purpose of reducing air humidity.

[0028] Water pump 135 can be in communication with water pan 127 and configured to be controlled to open to allow condensed water to flow into cooling line 136. That is, when water pump 135 is on, condensed water in water pan 127 can flow into cooling line 136; when water pump 135 is off, condensed water in water pan 127 does not flow into cooling line 136. Compressor 129 can be disposed in the cavity, with cooling line 136 coiled around the outside of compressor 129 to cool compressor 129 using the condensed water in cooling line 136.

[0029] Since the condensed water generated by the heat exchanger 120 carries cold air and has a relatively low temperature, a cooling pipe 136 can be coiled around the outside of the compressor 129. When the water pump 135 is turned on and the condensed water in the water receiving tray 127 flows into the cooling pipe 136, the low temperature of the condensed water can be used to cool down the compressor 129 and dissipate heat, thereby avoiding damage to the compressor 129 due to excessive cylinder temperature of the compressor 129 itself, thereby improving the working efficiency of the compressor 129 and extending its service life.

[0030] In a preferred embodiment, the cooling pipe 136 can be evenly coiled at regular intervals from top to bottom, thereby effectively cooling and dissipating heat from the entire compressor 129. It should be noted that the cooling pipe 136 can be made of a high-temperature resistant material. Thus, when the water pump 135 is turned off and condensed water does not flow into the cooling pipe 136, the cooling pipe 136 is not easily damaged by the high temperature of the compressor 129 cylinder, effectively extending the service life of the cooling pipe 136 and thereby improving overall operational reliability.

[0031] In summary, the dehumidifier 100 of this embodiment includes: a casing 110, which defines a cavity therein; a heat exchanger 120, which is arranged in the cavity and is configured to condense moisture in the air entering the cavity into condensed water; a water receiving tray 127, which is arranged below the heat exchanger 120 and is configured to receive the condensed water generated by the heat exchanger 120; a water pump 135, which is connected to the water receiving tray 127 and is configured to be opened in a controlled manner to allow the condensed water to flow into the cooling pipe 136; and a compressor 129, which is arranged in the cavity, and the cooling pipe 136 is coiled outside the compressor 129 to cool the compressor 129 by the condensed water in the cooling pipe 136. By cooling the compressor 129 by the condensed water in the cooling pipe 136 coiled outside the compressor 129, the compressor 129 can be effectively dissipated heat, thereby improving the working efficiency of the compressor 129 and extending its service life.

[0032] The dehumidifier 100 may further include a water level sensor (not shown in the figure) configured to detect the actual water level in the water receiving tray 127. Furthermore, if the actual water level is lower than a preset water level, the water pump 135 stops operating. Specifically, the water level sensor may be disposed in the water receiving tray 127 and may accurately detect the actual water level in the water receiving tray 127, reflecting the actual water level in the water receiving tray 127. If the actual water level is lower than the preset water level, it indicates that there is little condensed water in the water receiving tray 127 and the actual water level is too low. In this case, the water pump 135 may be controlled to stop operating in a timely manner to avoid affecting the operating performance and service life of the water pump 135.

[0033] Specifically, if the actual water level in the water receiving tray 127 is too low, the water pump 135 may encounter the following problems: when the pressure at the inlet of the water pump 135 is lower than the saturated vapor pressure of the medium, the water will vaporize to form bubbles. These bubbles will suddenly condense during the flow in the pump, generating impact force, causing surface erosion of the pump body and impeller, and generating noise. If the water level is too low, the water suction head of the water pump 135 will increase, so that the water pump 135 needs more energy to overcome gravity and pump water to the required height, reducing efficiency. If the inlet liquid level is too low, it is easy to generate vortexes, suck in air, and cause cavitation and reduce flow head. Therefore, when the actual water level is lower than the preset water level, the present embodiment stops the water pump 135 from running, which can effectively ensure the working performance of the water pump 135 and extend its service life.

[0034] In a preferred embodiment, dehumidifier 100 may further include a temperature sensor (not shown) configured to detect the actual temperature of compressor 129. Furthermore, water pump 135 is further configured to adjust the flow rate of condensed water flowing into cooling line 136 based on the actual temperature, where the flow rate is proportional to the actual temperature. Specifically, the temperature sensor may be located at compressor 129 to accurately detect the actual temperature of compressor 129 and reflect the actual temperature of compressor 129.

[0035] Water pump 135 can accurately adjust the flow rate of condensed water flowing into cooling line 136 based on the actual temperature of compressor 129. Specifically, the flow rate is proportional to the actual temperature. As the actual temperature of compressor 129 increases, water pump 135 adjusts the flow rate of condensed water flowing into cooling line 136 to a greater extent. This allows more condensed water to enter cooling line 136, promptly cooling and dissipating the high-temperature compressor 129, thereby ensuring the normal operation of compressor 129 and extending its service life.

[0036] When the actual temperature of the compressor 129 is lower, the water pump 135 adjusts the flow rate of the condensed water flowing into the cooling pipe 136 to a smaller value. Only a small amount of condensed water needs to enter the cooling pipe 136, which is sufficient to cool down the compressor 129, which has a relatively low temperature. Even when the actual temperature of the compressor 129 is lower than the preset temperature threshold, the water pump 135 can be directly turned off, eliminating the need for condensed water to enter the cooling pipe 136 to cool down the compressor 129 and dissipate heat. This can effectively reduce energy consumption and avoid unnecessary energy waste. Overall, the water pump 135 of this embodiment adjusts the flow rate of the condensed water flowing into the cooling pipe 136 according to the actual temperature, thereby improving the working performance of the dehumidifier 100 while effectively reducing energy consumption and enhancing the user experience.

[0037] In a specific embodiment, Figure 6 As shown, the water pump 135 may include an inlet pipe 137 and an outlet pipe 138, wherein the inlet pipe 137 is connected to the water receiving pan 127, and the outlet pipe 138 is connected to one end of the cooling pipe 136. In addition, the dehumidifier 100 may also include a drain pipe 139 connected to the other end of the cooling pipe 136, and the drain pipe 139 is configured to discharge condensed water to the outside. In other words, when the water pump 135 is turned on, the condensed water in the water receiving pan 127 can flow through the inlet pipe 137 and the outlet pipe 138 of the water pump 135 in sequence, then enter the cooling pipe 136 to cool and dissipate heat for the compressor 129, and finally be discharged to the outside of the dehumidifier 100 through the drain pipe 139.

[0038] In a preferred embodiment, a filter may be provided at the water inlet pipe 137 to filter impurities in the condensed water, thereby preventing impurities in the condensed water from entering and damaging the water pump 135. In conjunction with the aforementioned description of stopping the water pump 135 when the actual water level is lower than the preset water level, this can fully eliminate factors that affect the service life of the water pump 135 and ensure the operational reliability of the water pump 135.

[0039] In a specific embodiment, the dehumidifier 100 may further include: a water tank 123 and a partition 124. The water tank 123 is removably disposed in the cavity and is configured to accommodate condensed water. The removable arrangement of the water tank 123 in the cavity means that the user can easily take the water tank 123 out of or put it into the cavity. Specifically, Figure 3 As shown, the water tank 123 can be pulled out or put in from the rear bottom of the dehumidifier 100.

[0040] like Figure 3 and Figure 4 As shown, the partition 124 can be installed outside the water tank 123, and a water receiving pan 127 is formed on the top of the partition 124 to receive the condensed water generated by the heat exchanger 120. The water receiving pan 127 can be provided with a first water outlet and a second water outlet, wherein the first water outlet is higher than the second water outlet. The first water outlet is connected to the water tank 123, and the second water outlet is connected to the water inlet pipe 137.

[0041] Generally, the water receiving pan 127 may be provided with multiple water outlets with different water levels, and the first water outlet connected to the water tank 123 may have the highest water level, while the second water outlet connected to the water inlet pipe 137 may have the lowest water level. This ensures that when the actual water level in the water receiving pan 127 is between the first water outlet and the second water outlet, the condensed water is preferentially allowed to enter the water inlet pipe 137 through the second water outlet, and then flow through the cooling pipe 136 to cool and dissipate heat to the compressor 129, thereby fully ensuring the heat dissipation effect of the compressor 129.

[0042] When the actual water level in the water receiving pan 127 is higher than the first water outlet, it means that the actual water level in the water receiving pan 127 is very high. At this time, the condensed water can enter the water tank 123 through the first water outlet, and enter the cooling pipe 136 through the water inlet pipe 137, and finally be discharged to the outside through the drain pipe 139, effectively ensuring that the condensed water in the water receiving pan 127 is discharged smoothly and quickly, and avoiding the situation where the actual water level of the water receiving pan 127 is always too high and overflow occurs.

[0043] In other embodiments, outlets at other water levels may be provided between the first and second outlets of the water receiving tray 127 to achieve other functions according to actual needs. For example, a third outlet may be provided between the first and second outlets of the water receiving tray 127. That is, the water level at the third outlet may be lower than that at the first outlet and higher than that at the second outlet. The third outlet may be connected to a direct drain pipe to discharge the condensed water in the water receiving tray 127 directly to the outside of the dehumidifier 100.

[0044] In summary, the water pan 127 is provided with multiple water outlets. The first outlet can direct condensed water from the water pan 127 into the water tank 123, where it can be drained by the user emptying the water tank 123. The second outlet can direct condensed water from the water pan 127 into the cooling pipe 136 via the water pump 135, where it cools and dissipates heat from the compressor 129 before being drained to the exterior of the dehumidifier 100 through the drain pipe 139. The third outlet can drain condensed water from the water pan 127 directly to the exterior of the dehumidifier 100 through a straight drain pipe.

[0045] like Figure 3 and Figure 4 As shown, an electrical box 212 may be provided in front of the partition 124 to house electrical components. In a specific embodiment, the electrical components may include a computer board. Furthermore, the electrical components may include other electronically controlled devices, such as general-purpose capacitors and various cables. The computer board and other electrical components housed within the electrical box 212 enable control of the dehumidifier 100. Figure 3 The electrical box 212 is shown protruding from the front of the partition 124 .

[0046] In one specific embodiment, a cover can be provided on the electrical box 212 to seal the electrical box 212 and isolate the electrical components inside the electrical box 212 from the outside. In one specific embodiment, the cover can be snapped or screwed onto the electrical box 212. In this way, if an electrical component inside the electrical box 212 malfunctions, the cover can be easily removed to repair the internal electrical components. The provision of the cover isolates the electrical components inside the electrical box 212 from the outside, substantially protecting them from external influences, particularly from external refrigerant leakage.

[0047] In a preferred embodiment, the front portion of the partition 124 may be recessed rearward to form an escape space to accommodate electrical components. This allows the electrical components to be located entirely below the heat exchanger 120 without any contact therewith. Furthermore, the electrical components are separated from the compressor 129 by the thicker sidewalls of the escape space, and no cover or box gaps are provided between the electrical components and the compressor 129, meaning that there is no contact between the electrical components and the compressor 129 through any gaps.

[0048] By directly forming an escape space for accommodating electrical components on the partition 124 outside the water tank 123, the electrical components can be kept away from refrigerant-related components, such as the heat exchanger 120 and the compressor 129, effectively avoiding safety problems such as ignition of electrical components due to refrigerant leakage, ensuring safe use, and effectively improving the user experience; at the same time, the partition 124 and the electrical box 212 can be integrated, effectively optimizing the overall structure of the dehumidifier 100, improving the degree of integration, and making the distribution of various components inside the dehumidifier 100 more reasonable, compact, and precise.

[0049] In a specific embodiment, Figures 3 to 6 As shown, the middle part in front of the partition 124 is recessed backward to form a press chamber 128, and the compressor 129 is arranged at the press chamber 128. The water pump 135 is located on the left or right side of the compressor 129. Figure 3 The water pump 135 is shown to the right of the compressor 129. The electrical enclosure box 212 or escape space can be located on the left or right side of the front of the bulkhead 124. Figure 3 The electrical box 212 is shown to be located on the left side of the front of the partition 124. The center of the front of the partition 124 is left free to accommodate a compressor compartment 128 for accommodating a compressor 129, which is a more reasonable arrangement.

[0050] In a preferred embodiment, the water pump 135 is a diaphragm pump or an electromagnetic pump. The diaphragm pump can also be called a control pump. By receiving the control signal output by the modulation unit, the flow rate of the fluid is controlled under different power operations. It mainly uses compressed air as a power source, can absorb and transport various types of liquids, has a large flow rate and good passing performance; does not need to be filled with water, and has a high suction head; since the diaphragm pump has no rotating parts and pump shaft when it is started, the medium transported by the diaphragm pump is completely separated from the moving parts of the pump and the workpiece medium, and there is no leakage of the transported medium; the water head and flow rate can be adjusted by opening the air valve; the structure is simple, with few wearing parts, easy to maintain, the pumped medium will not contact valves and other components, and there will be no performance degradation due to rotors, pistons, impellers, etc.; it can operate normally without lubrication, which is very suitable for the working conditions of this embodiment.

[0051] The electromagnetic pump primarily consists of a pump head, a magnetic cylinder, a connecting base plate, and a motor. The magnetic cylinder is composed of inner and outer magnetic rotors and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field penetrates the gap and non-magnetic material, causing the inner magnetic rotor connected to the impeller to rotate synchronously, achieving power-free synchronous transmission. This transforms the leaky dynamic seal structure into a zero-leakage static seal structure. Because the pump shaft and the internal magnetic rotor are completely enclosed by the pump body and isolation sleeve, oil and air leaks are eliminated. Since the drive shaft does not need to penetrate the pump casing, the magnetic field drives the rotor through the air gap and the thin wall of the isolation sleeve to transmit torque, eliminating potential shaft seal leakage at the root and achieving complete sealing. The electromagnetic pump has an overload protection function to ensure safe and stable operation. The electromagnetic pump also requires less maintenance and overhaul work, making it well-suited to the operating conditions of this embodiment.

[0052] The partition 124 can have multiple support surfaces, thereby effectively improving the support strength. Specifically, the material of the partition 124 can be ABS (Acrylonitrile Butadiene Styrene) or HIPS (High Impact Polystyrene). In a preferred embodiment, the partition 124 can be injection molded in one step using gas-assisted molding technology. Gas-assisted injection molding (GAIM) technology, also known as gas-assisted molding technology, is a new type of injection molding processing technology that can use high-pressure inert gas to push the melt to fill the mold cavity. By maintaining the gas pressure, a hollow section is formed inside the thick-walled plastic part. It is very suitable for plastic parts such as the partition 124 in this embodiment whose wall thickness is uneven and cannot be traditionally injection molded in one step.

[0053] Gas-assisted molding technology addresses the shortcomings of traditional injection molding and structural foam molding. Using high-pressure nitrogen, it hollows out the thickest areas of the molded part's wall, creating a hollow section within the part. The gas maintains pressure, promoting melt filling and eliminating surface sink marks, while also avoiding the drawback of structural foam parts that are unsuitable for spraying. This significantly reduces costs while ensuring high product quality. In summary, the partition 124 of this embodiment can be injection-molded in a single pass using gas-assisted molding, eliminating the need for subsequent secondary processing. This approach offers low cost and high efficiency.

[0054] like Figure 3 As shown, heat exchanger 120 can be located above partition 124. As mentioned above, a water receiving pan 127 is formed on the top of partition 124 to receive condensed water generated by heat exchanger 120. A water inlet is formed on the top of water tank 123 opposite to the first water outlet of water receiving pan 127, allowing condensed water to flow from water receiving pan 127 into water tank 123.

[0055] Specifically, the water tank 123 may include a main body and a cover. The interior of the main body can accommodate condensed water, and the cover is provided on the main body to seal the interior of the main body. In addition, a handle may be provided on the cover. After the user pulls out the water tank 123, the user can directly carry the handle on the cover to the bathroom or other places to pour out the condensed water inside the water tank 123. The provision of the handle greatly improves the convenience of the user in discharging condensed water. It should be noted that the cover can be tightly locked on the main body to prevent the cover from opening when the user pulls the handle. In a specific embodiment, a first water outlet may be provided on the right side of the water receiving tray 127 at the top of the partition 124, and correspondingly, a water inlet may be provided on the right side of the cover of the water tank 123.

[0056] The compressor 129 can pressurize and heat the refrigerant so that it can be converted from a gaseous state to a liquid state under high pressure and high temperature. In a specific embodiment, the heat exchanger 120 may include: an evaporator 121 and a condenser 122. The evaporator 121 and the condenser 122 are the core components of the dehumidifier 100 and are important factors for the dehumidifier 100 to achieve dehumidification. The evaporator 121 mainly plays a moisture absorption role and can also be called a "water extractor". The evaporator 121 absorbs moisture in the air at low temperature, converts it into water vapor, and then transfers the water vapor to the condenser 122, and the condenser 122 can condense the water vapor into condensed water.

[0057] The evaporator 121 is located outside the condenser 122. The air entering the housing 110 of the dehumidifier 100 flows through the evaporator 121 and the condenser 122 in sequence. After the moisture in the air entering the cavity condenses into condensed water, the air with reduced humidity is discharged from the dehumidifier 100. This cycle is repeated to achieve the purpose of indoor dehumidification. In a preferred embodiment, Figure 3 As shown, both the evaporator 121 and the condenser 122 can be U-shaped fin-and-tube heat exchangers with their openings facing forward. More specifically, the evaporator 121 can employ a conventional U-shaped hydrophilic fractured fin-and-tube heat exchanger, and the condenser 122 can employ a conventional U-shaped fractured fin-and-tube heat exchanger. However, neither the evaporator 121 nor the condenser 122 is limited to inline, V-shaped, or L-shaped configurations.

[0058] In a specific embodiment, Figure 1 and Figure 2 As shown, the housing 110 may include: a top cover 111 and three panels 112, and air inlets 116 are provided on the left, right, and rear sides of the three panels 112 to allow external air to enter the cavity. Filters 133 may be provided at the air inlets 116 corresponding to the three sides of the three panels 112, so as to perform preliminary filtration on the air entering the cavity, thereby improving the cleanliness of the air flowing through the cavity and also improving the air quality of the indoor environment. It should be noted that Figures 1 to 6 The front, back, left and right positions of the dehumidifier 100 shown are only examples. In other embodiments, the positions may be based on the actual usage of the user, but the relative positional relationship of the components remains unchanged.

[0059] Top cover 111 is provided with an air outlet 117 for exhaust of air passing through heat exchanger 120. Specifically, outside air can enter the cavity through air inlet 116 of three panels 112. Moisture in the air is then condensed into condensed water by heat exchanger 120. The air with reduced humidity is then discharged from dehumidifier 100 through air outlet 117 of top cover 111. The entire path from air flowing into the cavity from air inlet 116 to air flowing out of dehumidifier 100 through air outlet 117 can be referred to as an air duct.

[0060] More specifically, the housing 110 may further include: a front panel 113, a left side panel 114, a right side panel 115 and a bottom panel 118. Among them, a power connector 134 may be provided on the front panel 113 to power the dehumidifier 100. In addition, the power connector 134 is located at the front of the dehumidifier 100, and is far away from the water tank 123 at the rear of the dehumidifier 100, to avoid the impact of condensed water splashing when the water tank 123 is pulled out, thereby ensuring safe use. The left side panel 114 may be located below the left side of the three-panel panel 112, and the right side panel 115 may be located below the right side of the three-panel panel 112. The left side panel 114 and the right side panel 115 respectively shield the left and right sides of the partition 124. The base plate 118 is located at the bottom of the entire dehumidifier 100, and pulleys 119 can be provided at the four corners of the base plate 118, so that the user can move the dehumidifier 100 conveniently, and move the dehumidifier 100 to different indoor environments or different locations in the indoor environment for dehumidification.

[0061] The housing 110 of the dehumidifier 100 of this embodiment is configured with multiple detachable parts, which not only facilitates assembly but also facilitates maintenance. Specifically, if a component within the dehumidifier 100 malfunctions, the corresponding portion of the housing 110 can be removed for repair without dismantling the entire housing 110. For example, if the compressor 129 malfunctions, only the front panel 113 can be removed to expose the compressor 129 and repair it.

[0062] In a specific embodiment, the dehumidifier 100 may further include: a bracket 131, a motor and a fan 132. The bracket 131 is arranged below the top cover 111. The motor is fixed to the bracket 131 and is configured to drive the fan 132 to rotate. The fan 132 is configured to promote the flow of external air into the cavity. Through the action of the fan 132, the external air can smoothly flow into the cavity through the air inlet 116, and be discharged through the air outlet 117 after passing through the heat exchanger 120. The fan 132 helps to promote air circulation and effectively improve the dehumidification efficiency.

[0063] In a preferred embodiment, the fan 132 of the dehumidifier 100 can be a DC fan, which can provide high air volume and low noise. The high air volume, low noise, and long life of the DC fan not only ensure the efficient operation of the dehumidifier 100, but also maintain a low noise level, providing a comfortable user environment and enhancing the user experience.

[0064] In addition, the dehumidifier 100 may also include: a throttling device, which can reduce the pressure and temperature of the liquid refrigerant after cooling in the condenser 122, so that it can be converted from a liquid state to a low-pressure and low-temperature vapor-liquid mixed state. In a specific embodiment, the throttling device can be an expansion valve or a capillary tube. In addition to the functions of the condenser 122 and the evaporator 121 mentioned above, the condenser 122 is a heat dissipation device in the dehumidifier 100, which dissipates the heat of the high-temperature and high-pressure refrigerant in the compressor 129 and converts it from a gaseous state to a liquid state. The evaporator 121 is a heat absorption device in the dehumidifier 100, which absorbs heat from the air to convert the refrigerant from a liquid state to a gaseous state, thereby absorbing moisture from the air.

[0065] In general, the internal circulation of the dehumidifier 100 may include: through the operation of the compressor 129, high-temperature and high-pressure gas is discharged from the exhaust port, enters the condenser 122 for cooling, becomes low-temperature and high-pressure gas, is throttled by the throttling device, is filtered through the filter, becomes a low-temperature and low-pressure liquid, evaporates and absorbs heat through the evaporator 121, returns to the compressor 129 and becomes a low-temperature and low-pressure gas, and so on. The external circulation of the dehumidifier 100 may include: through the operation of the fan 132, humid air is sucked in from the air inlet 116, passes through the evaporator 121 to condense water vapor in the air into water and adsorbed on the aluminum sheet, the humid air becomes dry air, passes through the condenser 122 to heat up and dissipate heat, and blows out dry gas from the air outlet 117, and so on and so forth to reduce the indoor humidity.

[0066] The dehumidifier 100 may also include a temperature and humidity sensor for detecting the humidity and temperature of the indoor environment in which the dehumidifier 100 is located. The humidity and temperature detected by the temperature and humidity sensor can be used to accurately adjust the operating state of the dehumidifier 100. For example, if the detected humidity is higher than a preset humidity, the indoor humidity can be considered too high, affecting the user's comfort and health. The dehumidifier 100 can then be controlled to start dehumidification, reducing the indoor humidity, improving the user's comfort, and protecting their health.

[0067] In a specific embodiment, the dehumidifier 100 may further include a display panel for displaying relevant information about the dehumidifier 100, such as the operating mode and the set humidity. Upon receiving a start trigger signal, the dehumidifier 100 may start operating to dehumidify. In a preferred embodiment, the start trigger signal may be received from a user via the dehumidifier 100's display device, voice control device, remote control, or a mobile terminal associated with the dehumidifier 100. The mobile terminal may be a portable smart device, such as a smartphone or tablet computer.

[0068] In summary, the dehumidifier 100 of this embodiment includes: a casing 110, which defines a cavity therein; a heat exchanger 120, which is arranged in the cavity and is configured to condense moisture in the air entering the cavity into condensed water; a water receiving tray 127, which is arranged below the heat exchanger 120 and is configured to receive the condensed water generated by the heat exchanger 120; a water pump 135, which is connected to the water receiving tray 127 and is configured to be opened in a controlled manner to allow the condensed water to flow into the cooling pipe 136; and a compressor 129, which is arranged in the cavity, and the cooling pipe 136 is coiled outside the compressor 129 to cool the compressor 129 by the condensed water in the cooling pipe 136. By cooling the compressor 129 by the condensed water in the cooling pipe 136 coiled outside the compressor 129, the compressor 129 can be effectively dissipated heat, thereby improving the working efficiency of the compressor 129 and extending its service life.

[0069] Furthermore, the dehumidifier 100 of this embodiment also includes: a water level sensor and a temperature sensor, wherein the water level sensor is configured to detect the actual water level in the water receiving tray 127, and when the actual water level is lower than the preset water level, the water pump 135 stops running, and a filter is provided at the water inlet pipe 137 of the water pump 135 to filter out impurities in the condensed water, fully eliminate factors that affect the service life of the water pump 135, and ensure the working reliability of the water pump 135; the temperature sensor is configured to detect the actual temperature of the compressor 129, and the water pump 135 is further configured to: adjust the flow rate of the condensed water flowing into the cooling pipe 136 according to the actual temperature, wherein the flow rate is proportional to the actual temperature, thereby improving the working effect of the dehumidifier 100 while effectively reducing energy consumption and improving the user experience.
