Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification equipment, and particularly relates to a heat dissipation component of a dehumidifier, a dehumidifier and a control method thereof. Background Art

[0002] A dehumidifier uses a compression system to condense moisture in the air into condensed water and collect it in a water tank. There is a control method for an existing dehumidifier that utilizes the condensed water in the water tank. A water level detection unit is set at a certain water level in the water tank and a spraying system is set. When the water storage in the water tank reaches the detected water level, the spraying system starts to work to pump the condensed water in the water tank to a water-cooled pipe. The water-cooled pipe has a heat interaction with the heat exchange pipe of the condenser, so as to water-cool the airflow passing through the condenser to achieve a certain cooling effect.

[0003] Now it is desired to use the condensed water to dissipate heat from the heat-generating working units inside the dehumidifier. Summary of the Invention

[0004] The first object of the present invention is to provide a heat dissipation component of a dehumidifier that uses condensed water to dissipate heat from the heat-generating working units inside the dehumidifier.

[0005] The second object of the present invention is to provide a dehumidifier that uses condensed water to dissipate heat from the heat-generating working units inside the machine.

[0006] The third object of the present invention is to provide a control method for a dehumidifier.

[0007] The heat dissipation component of the dehumidifier provided by the first object of the present invention includes a water receiving tray and a water tank. The water receiving tray is located below the heat exchanger setting position and above the heat-generating working unit setting position, and the water receiving tray is provided with a drain port; it further includes a water storage tank. The water storage tank is provided with a vertical water storage space, and the drain port is vertically communicated with the entrance of the water storage space. When the water in the water storage tank overflows, it flows to the water tank; the water storage tank further includes a heat conduction wall, and the heat conduction wall is blocked between the water storage space and the heat-generating working unit setting position.

[0008] As can be seen from the above solution, the present invention uses the position between the water tank and the compressor and the electrical box to set up a water storage tank. The water storage tank serves as a water-cooling device that directly conducts heat interaction with the electrical box and / or the compressor. The condensed water in the water receiving tray directly falls into the water storage space of the water storage tank; the heat of the electrical box and / or the compressor is conducted by the heat conduction wall to the condensed water in the water storage space and is absorbed by the condensed water. The condensed water after heat absorption finally overflows into the water tank. In this way, the present invention uses condensed water to dissipate heat from the electrical box and / or the compressor during operation through water cooling, thereby effectively reducing the internal temperature of the equipment, improving the operation efficiency and extending the service life.

[0009] A further solution is that an overflow port is provided in the water storage tank, the water storage space is connected to the overflow port, and the overflow port is higher than the inlet of the water tank; and an overflow slope is also provided, and the overflow slope is provided between the overflow port and the inlet of the water tank.

[0010] As can be seen from the above, the setting of the overflow port ensures that the water storage tank overflows into the water tank when it is full; the inclined overflow slope guides the overflow water.

[0011] Another further solution is that the water storage tank is separated between the heating working unit setting position and the water tank.

[0012] As can be seen from the above, this setting optimizes the internal layout of the dehumidifier, and isolates the thermal interaction between the heating working unit and the water tank containing the water that absorbs heat and heats up through the water storage tank, thereby avoiding the secondary impact of the water tank on the heating working unit.

[0013] A further solution is that the heating working unit setting position, the water storage tank and the water tank are arranged in sequence along the first direction, and the heat conduction wall extends along the second direction.

[0014] It can be seen from the above that under this setting, the arrangement between the heating working unit, the water storage tank and the water tank is more reasonable, and is more in line with the internal layout of most existing rectangular or nearly rectangular outer contours of the body. More importantly, under this setting, the heat conduction wall is extended to a greater extent, ensuring the absorption of heat from all working units in the setting position of the heating working unit, further improving the heat dissipation effect.

[0015] Another further solution is that it also includes a spray system; the spray system includes a nozzle, a water pipe and a water pump arranged on the water pipe, the water inlet end of the water pipe is arranged in the water storage space, the water outlet end of the water pipe is connected to the nozzle, and the nozzle is arranged toward the water tank.

[0016] As can be seen above, the spray system and nozzle are used to achieve self-cleaning of the water tank. The inner wall of the water tank is cleaned with water pumped out by the water pump. The installation position of the nozzle has been optimized to ensure that the inner wall of the water tank can be fully cleaned, which can effectively prevent the contamination of condensed water in the water tank and the growth of bacteria, and further improve the performance of the equipment and user experience.

[0017] A further solution is that the spray system also includes a filter element, and the filter element is connected to the water inlet end.

[0018] As can be seen from the above, the provision of the filter element further prevents condensed water in the water tank from being contaminated and inhibits bacterial growth.

[0019] Another further solution is that it also includes a first water level detection unit and a second water level detection unit, the first water level detection unit is connected to the water tank or the water receiving tray and is set at a first horizontal height, the first water level detection unit is connected to the water tank or the water receiving tray and is set at a second horizontal height, and the first horizontal height is higher than the second horizontal height.

[0020] As can be seen from the above, the first water level detection unit is used to judge the water level in the self-circulation mode. If the water level condition is met, the water in the water storage tank is pumped out, and the inner wall of the water tank is cleaned through the nozzle; the second water level detection unit is used to judge the water level when the machine is shut down. If the water level condition is met, the water in the water storage tank is pumped out, reducing the potential safety hazard caused by the condensate residue.

[0021] The dehumidifier provided by the second object of the present invention includes a heating working unit, and the heating working unit includes a compressor and / or an electrical box; it also includes the above-mentioned dehumidifier heat dissipation assembly; the heating working unit is arranged at the heating working unit setting position.

[0022] A further solution is that the electrical box is connected to the heat-conducting wall.

[0023] As can be seen from the above, the electrical box is not a vibration source like the compressor, and the electrical box generates a large amount of heat. In this setting, it can ensure that the heat of the electrical box is absorbed as much as possible without vibration intensification, greatly improving the heat dissipation effect on the electrical box.

[0024] In the dehumidifier control method provided by the third object of the present invention, the dehumidifier includes a heating working unit, and the heating working unit includes a compressor and / or an electrical box. The dehumidifier also includes the above-mentioned dehumidifier heat dissipation assembly, and the heating working unit is arranged at the heating working unit setting position; the dehumidifier control method includes determining to enter the self-circulation module: judging whether the water level in the water storage space is higher than or equal to the first preset value according to the first detection signal obtained through the first water level detection unit. If so, controlling to start the water pump; if it is determined to obtain a shutdown instruction; judging whether the water level in the water storage space is higher than or equal to the second preset value according to the second detection signal obtained through the second water level detection unit. If so, controlling to start the water pump.

[0025] As can be seen from the above solutions, in the self-circulation mode, when the water level reaches the set value, the water pump will automatically start, pumping out the water in the water storage tank, and cleaning the inner wall of the water tank through the nozzle. Whether it is the default mode or the self-circulation mode, when the user turns off the dehumidifier, the system will detect whether there is water in the water storage tank. When there is condensate in the water storage tank, the water pump will automatically start to completely drain the water in the water storage tank. The dehumidifier control method of the present invention efficiently utilizes the condensate, achieving the effects of both heat dissipation and self-cleaning of the water tank, while reducing the potential safety hazard caused by the condensate residue.

[0032] Embodiment of the heat dissipation component of the dehumidifier and the dehumidifier Refer to Figures 1 to 4 , Figure 3 and Figure 4 In the coordinate system shown in, the y-axis direction represents the first direction of the present invention, the z-axis direction represents the second direction of the present invention, the z-axis direction represents the vertical direction, and both the first direction and the second direction are horizontal directions.

[0033] The dehumidifier of this embodiment includes a heat dissipation component of the dehumidifier, a heat exchanger (not shown), and a heating working unit of the present invention. Among them, the heating working unit of this embodiment includes an electrical box 91 and a compressor 92.

[0034] The heat dissipation component of the dehumidifier includes a water receiving tray 1, a water tank 2, a water storage tank 3, a spray pipe system 4, a first water level detection unit 51, a second water level detection unit 52, and a drain pipe 53.

[0035] Among them, the heat exchanger is arranged at the heat exchanger installation position 901, the water receiving tray 1 is arranged below the heat exchanger installation position 901 to receive the condensed water dripping from the heat exchanger, and the water tank 2, the water storage tank 3, the electrical box 91, and the compressor 92 are all arranged below the water receiving tray 1. Among them, the positions where the electrical box 91 and the compressor 92 are located are the heating working unit installation position 902 of the present invention.

[0036] Furthermore, as Figure 3 shown, the heating working unit installation position 902, the water storage tank 3, and the water tank 2 are arranged in sequence along the first direction. As Figure 4 shown, the heat conducting wall 31 extends along the second direction, so that in the first direction, the water storage tank 3 is blocked between the heating working unit installation position 902 and the area 903. The water tank is arranged in the area 903.

[0037] A water storage space 30 is formed vertically in the water storage tank 3. The drain port 101 of the water receiving tray 1 is vertically communicated with the inlet 301 of the water storage space 30. The water storage tank 3 is further provided with an overflow port 302, and the water storage space 30 is communicated with the overflow port 302. The overflow port 302 is higher than the inlet at the top of the water tank 2. The heat dissipation assembly further includes an overflow slope 32. The overflow slope 32 can be a separate part or integrally formed with the water storage tank 3. The overflow slope 32 is arranged between the overflow port 302 and the inlet of the water tank 2, and the guiding slope surface of the overflow slope 32 is inclined downward from the overflow port 302 to the inlet of the water tank 2. In this way, when the water in the water storage tank 3 overflows, it flows to the water tank 2 through the overflow port 302 and the overflow slope 32.

[0038] Crucially, one of the side walls of the water storage tank 3 that surrounds the water storage space 30 is the heat-conducting wall 31 of the present invention. The heat-conducting wall 31 is located on one side of the water storage tank 3 facing the setting position 902 of the heat-generating working unit. Therefore, the heat-conducting wall 31 is blocked between the water storage space 30 and the setting position 902 of the heat-generating working unit. In this embodiment, the heat-conducting wall 31 is a flat wall body extending in the second direction, and the heat-conducting wall 31 has a surface facing the setting position 902 of the heat-generating working unit, and this surface is set as a plane. In one setting method, the entire water storage tank 3 is made of a material with good heat-conducting performance, so that the heat-conducting wall 31 has good heat-conducting performance; in another setting method, the water storage tank 3 includes the heat-conducting wall 31 and a second component other than the heat-conducting wall 31. After the heat-conducting wall 31 is installed on the second component, the water storage space 30 is formed. The heat-conducting wall 31 is made of a material different from that of the second component. Specifically, the heat-conducting member 31 has better heat conductivity than the second component to ensure the heat transfer effect of the heat-conducting member 31, and also takes into account the manufacturing difficulty and manufacturing cost of the second component.

[0039] On the other hand, the size of the water storage tank 3 in the first direction is small, so that the water storage tank 3 is similar to a wall, and the first direction is the wall thickness direction of the wall. Further, in the first direction, the size of the water storage tank 3 is smaller than the size of the box body 2. Further still, in the first direction, the size of the water storage tank 3 is less than half of the size of the box body 2.

[0040] In the first direction, due to the small thickness of the water storage tank 3, the corresponding thickness of the heat-conducting wall 31 is also small, and the water storage space 30 is also a relatively narrow space. The advantages of such a setting are as follows: First, the water storage tank 3 occupies a small space inside the dehumidifier and does not affect the size of the machine body; second, the small thickness of the heat-conducting wall 31 reduces the thermal resistance and improves the heat transfer efficiency; third, the water storage space 30 is relatively narrow and has a smaller volume. It is easier to fill the water storage space 30 with water and cover the heat-conducting wall 31, increasing the heat transfer area and improving the heat dissipation effect. In addition, the condensed water is more likely to contact the heat-conducting wall 31 during the falling process from the water receiving tray 1 to assist in improving the heat dissipation efficiency.

[0041] The spraying system 4 includes a water pipe 41, a water pump 42, a nozzle 43 and a filter member 44. The filter member 44 is a filter net component. The filter member 44 is sleeved on the water inlet end of the water pipe 41, and the water inlet end of the water pipe 41 is arranged at the bottom of the water storage space 30; the water outlet end of the water pipe 41 is connected to the nozzle 43, and the nozzle 43 is arranged in the water tank 2 and faces the inner wall of the water tank 2. The water pump 42 is arranged on the water pipe 41, and the water pump 42 is arranged on the water receiving tray 1. After the water pump 42 is started, the water in the water storage space 30 can be pumped out and finally sprayed and cleaned on the inner wall surface of the water tank 2 through the nozzle 43.

[0042] In addition, the first water level detection unit 51 is connected to the water storage tank 3 or the water receiving tray 1 and is arranged at a first horizontal height, and the first water level detection unit 51 is connected to the water storage tank 3 or the water receiving tray 1 and is arranged at a second horizontal height. Wherein, the horizontal height at which the water level detection unit is arranged refers to the detected water level of the water level detection unit.

[0043] Among them, the first water level detection unit 51 is used to detect whether the water storage capacity in the water storage tank 3 is large. Therefore, the first horizontal height is a relatively high horizontal height. For example, the first horizontal height is above the midline in the height direction of the water storage space 30. Preferably, the first horizontal height is slightly lower than the horizontal height of the lowest point of the overflow port 302. For example, the first horizontal height is 2 cm lower than the horizontal height of the lowest point of the overflow port 302.

[0044] However, the second water level detection unit 52 is used to detect whether there is water residue in the water storage tank 3 when the machine is turned off. Therefore, the second horizontal height is a relatively low horizontal height. For example, the second horizontal height is below the midline in the height direction of the water storage space 30. Preferably, the second horizontal height is set at a position close to the bottom of the water storage space 30. For example, the second horizontal height is 2 cm higher than the bottom of the water storage space 30.

[0045] In addition, a drain pipe 53 can be connected to the water storage tank 3, and the drain pipe 53 communicates with the bottom of the water storage space 30. Preferably, an electric control valve is arranged at the drain hole where the water storage tank 3 is connected to the drain pipe 53. In this setting, according to the user's setting or a preset program, after it is determined by the second water level detection unit 52 that there is water residue in the water storage tank 3, the drain hole can be opened by controlling the electric control valve to drain water through the drain pipe 53, or the water pump 42 can be controlled to start pumping water.

[0046] See Figure 2, in this embodiment, the electrical box 91 is connected to the heat-conducting wall 31. Specifically, the flat surface of the electrical box 91 is in mutual contact with the flat surface of the heat-conducting wall 31. Preferably, a heat-dissipating silicone grease is coated between the flat surface of the electrical box 91 and the flat surface of the heat-conducting wall 31. In addition, the compressor 92 is arranged at a certain distance from the heat-conducting wall 31. The electrical box 91 is not a vibration source like the compressor 92, and the electrical box 91 generates a large amount of heat. In this setting, it can ensure that the heat of the electrical box 91 is absorbed as much as possible without causing increased vibration, greatly improving the heat dissipation effect on the electrical box 91.

[0047] Primarily, the present invention sets a water storage tank 3 at the positions among the water tank 2, the compressor 92, and the electrical box 91. The water storage tank 3, as a water-cooling device that directly conducts heat interaction with the electrical box 91 and the compressor 92, the condensed water in the water receiving tray 1 directly falls into the water storage space 30 of the water storage tank 3. During the process of the condensed water falling and being pumped away, the heat of the electrical box 91 and / or the compressor 92 is conducted by the heat-conducting wall 31 to the condensed water in the water storage space 30 and is absorbed by the flowing condensed water. The condensed water after heat absorption finally overflows into the water tank 2 or is pumped into the water tank 2. Thus, the present invention uses the condensed water to dissipate heat from the electrical box 91 and the compressor 92 during the working process through water cooling, thereby effectively reducing the internal temperature of the device, improving the operating efficiency, and extending the service life.

[0048] Embodiment of the dehumidifier control method The dehumidifier control method is implemented based on the dehumidifier of the above embodiment.

[0049] The dehumidifier control method includes: See Figure 5 And in combination with Figures 1 to 4 , if it is determined to enter the self-circulation module: Execute step S1 to enter the self-circulation module; Subsequently, execute step S2. According to the first detection signal obtained by the first water level detection unit 51, determine whether the water level in the water storage space 30 is higher than or equal to the first preset value. If so, execute step S3 to control the opening of the water pump 42; if not, execute step S4 to maintain the current state of the closed water pump 42 and continue to execute step S2 to continuously judge the water level.

[0050] In the self-circulation mode, when the water level reaches the set value, the water pump 42 will be automatically turned on to pump out the water in the water storage tank 3 and clean the inner wall of the water tank 2 through the nozzle 43.

[0051] See Figure 6 And in combination with Figures 1 to 4 , execute the judgment step S11 to judge whether a shutdown instruction is obtained.

[0052] If the judgment result is yes, the judgment step S6 is executed to judge whether the water level of the water storage space 30 is higher than or equal to the second preset value according to the second detection signal obtained by the second water level detection unit 52 .

[0053] If yes, then step S7 is executed to control the water pump 42 to be turned on, and step S6 is continued to continuously judge the water level.

[0054] If not, the thief executes step S8 to keep the current state of closing the water pump 42.

[0055] In another embodiment, when the judgment result of step S6 is yes, the electric control valve of the drain pipe 53 is controlled to open for drainage. In this way, when the dehumidifier is turned off, if there is condensed water in the water storage tank, the water pump will automatically start to completely drain the water in the water storage tank. In particular, when the spray system is used for drainage, the condensed water is efficiently utilized to achieve the ability of both heat dissipation and self-cleaning of the water tank, while also reducing the safety hazards caused by residual condensed water.

[0056] In other embodiments of the heat dissipation assembly of the dehumidifier, an opening and closing device for controllably blocking the drain outlet is also provided at the drain outlet of the water receiving tray, and a third water level detection unit is provided at a certain water level of the water receiving tray, and a flow guiding structure is provided in the water storage tank, the flow guiding structure includes a flow guiding surface, the flow guiding surface is located below the entrance of the water storage space, and the flow guiding surface gradually approaches the heat conduction wall and extends downwardly and obliquely. Under this setting, the drain outlet can be closed by the opening and closing device to store water in the water receiving tray, and the water storage amount of the water receiving tray can be detected by the third water level detection unit. When the water storage amount of the water receiving tray reaches a certain level, the opening and closing device is opened again, and the water stored in the water receiving tray becomes a water flow that rushes downward into the water storage space and rushes to the flow guiding surface, and then rushes toward the heat conduction wall under the guidance of the inclined flow guiding surface. This setting can greatly improve the heat dissipation effect.

[0057] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
