[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope protected by the present invention.

[0043] Embodiment 1:

[0044] This embodiment provides a compressor cooling device for a dehumidifier to solve the technical problems of high economic cost and poor heat dissipation effect existing in the compressor cooling device of the existing dehumidifier.

[0045] The compressor cooling device of the dehumidifier includes a water pump 1, a first heat exchange structure 3 and a return water pipe 4.

[0046] The above-mentioned water pump 1 is a small pump body, and the water pump 1 is installed on the water tank 2 of the dehumidifier to extract the condensed water in the water tank 2. It should be noted that the water tank 2 of the dehumidifier can catch and collect the condensed water generated during the operation of the dehumidifier.

[0047] The above-mentioned first heat exchange structure 3 is made of a material with good thermal conductivity, such as copper or aluminum. A channel for water to flow through is provided inside the first heat exchange structure 3. The channel has an inlet 311 and an outlet 312. Specifically, the inlet 311 of the channel is connected to the outlet of the above-mentioned water pump 1 through a first pipeline, that is, the water pump 1 can pump the water in the water tank 2 into the above-mentioned channel. During installation, the outer wall of the first heat exchange structure 3 is connected to the outer wall of the compressor of the dehumidifier so that the first heat exchange structure 3 is in contact with the outer wall of the compressor. In this way, the heat generated during the operation of the compressor of the dehumidifier will be transferred into the above-mentioned channel, thereby heating the condensed water in the channel. With the operation of the above-mentioned water pump 1, the water in the above-mentioned channel can flow, so that circulating water is formed in the channel, thereby cooling the above-mentioned first heat exchange structure 3, and further dissipating heat from the compressor of the dehumidifier, avoiding the adverse effects caused by the too high temperature of the compressor.

[0048] One end of the above-mentioned return pipe 4 is connected to the outlet 312 of the above-mentioned channel, and the other end of the return pipe 4 is communicated with the above-mentioned water tank 2. When the water pump 1 operates, the condensed water in the above-mentioned channel will enter the above-mentioned return pipe 4 and flow back into the water tank 2 of the dehumidifier through the diversion of the return pipe 4, thus forming a cycle.

[0049] Specifically, the other end of the above-mentioned return pipe 4 is arranged above the opening of the water tank 2, and the water in the return pipe 4 will directly drip into the water tank 2 from the opening of the water tank 2. More preferably, a pipe joint 5 communicated with the water tank 2 is installed on the tank wall of the above-mentioned water tank 2, and a second pipeline is connected to the pipe joint 5, and the free end of the second pipeline is connected to the inlet of the above-mentioned water pump 1.

[0050] As a more preferred implementation method of this embodiment, in this embodiment, a liquid level sensor is further provided in the above-mentioned water tank 2. The liquid level sensor can sense the level of the liquid in the above-mentioned water tank 2, and the liquid level sensor is connected to a controller (such as a PLC), and the controller controls whether the above-mentioned water pump 1 operates or not. The pipe joint 5 is installed at a position slightly below the middle of the water tank 2. When the liquid level sensor senses that the water in the water tank 2 is less than half of the water tank 2, the controller controls the water pump 1 not to start. When the liquid level sensor senses that the water in the water tank 2 reaches half of the water tank 2, the controller controls the water pump 1 to start.

[0051] Embodiment 2:

[0052] As a specific implementation manner of Embodiment 1, in this embodiment, the first heat exchange structure 3 includes a box body 31 and a plate body 32 that are detachably and fixedly connected together. The box body 31 is buckled on one side plate surface of the plate body 32, and the box body 31 and the plate body 32 can be bonded together by high-temperature resistant glue or connected together by other connection methods (such as screw connection, etc.). Moreover, a first sealing ring is arranged between the box body 31 and the plate body 32. At this time, a channel is formed between the box wall of the box body 31 and the plate surface of the plate body 32, and the inlet 311 and the outlet 312 are arranged on the side wall of the box body 31. That is, the condensed water pumped by the water pump 1 enters the inside of the box body 31, thereby cooling / heat-exchanging the plate body 32. The plate body 32 is in contact with the outer wall of the compressor of the dehumidifier to cool the compressor. The first heat exchange structure 3 has the advantages of simple structure and convenient manufacturing.

[0053] As a more optimal implementation manner of this embodiment, in this embodiment, a plurality of fins 321 are arranged on one side plate surface of the plate body 32, and the plurality of fins 321 are spaced apart. All the fins 321 are embedded in the box body 31. Preferably, the structure formed by all the fins 321 is adapted to the shape of the internal cavity of the box body 31, that is, the structure formed by all the fins 321 can just be inserted into the internal cavity of the box body 31. In this way, the heat exchange area can be increased to improve the heat exchange efficiency, making the cooling effect more efficient, and a water channel is formed between two adjacent fins 321 to guide the water flow in the above-mentioned channel.

[0054] As a more optimal implementation manner of this embodiment, in this embodiment, a heat-conducting silica gel 322 is arranged on the other side plate surface (the plate surface facing away from the box body 31) of the plate body 32. During use, the other side plate surface of the plate body 32 is attached to the outer wall of the compressor of the dehumidifier. The setting of the heat-conducting silica gel 322 can improve the efficiency of heat conduction and thus improve the cooling effect.

[0055] As a best implementation manner of this embodiment, in this embodiment, one or more support plates 323 are arranged on the outer edge of the plate body 32, and the support plates 323 are bonded to the outer wall of the compressor by high-temperature resistant glue, so as to achieve the purpose of connecting the plate body 32 (that is, the first heat exchange structure 3) to the compressor of the dehumidifier.

[0056] As another implementation manner of this embodiment, in this embodiment, the box body 31 and the water pump 1 are connected together, so that the structure can be further made more compact and the lean production can be improved.

[0057] Embodiment 3:

[0058] As a more optimal implementation of the above embodiment, the compressor cooling device of the dehumidifier provided in this embodiment further includes a second heat exchange structure 6, which is connected and provided on the above-mentioned return water pipe 4. In this way, the water coming out of the above-mentioned first heat exchange structure 3 will enter the above-mentioned second heat exchange structure 6.

[0059] Similar to the prior art, the dehumidifier provided in this embodiment also includes an air duct 7, in which a fan 8 is installed. The above-mentioned second heat exchange structure 6 is installed in the above-mentioned air duct 7, so as to use the air blown by the fan 8 to air-cool the second heat exchange structure 6, so as to air-cool the water in the second heat exchange structure 6 (that is, the water in the return water pipe 4), and further make the temperature of the water flowing back to the water tank 2 appropriate.

[0060] As a specific implementation of this embodiment, the second heat exchange structure 6 in this embodiment includes a main pipe 61, a heat exchange pipe 62, and fins 63 for heat dissipation. The above-mentioned main pipe 61 is a straight pipe, and both ends of the main pipe 61 are connected to the return water pipe 4. The above-mentioned heat exchange pipe 62 is connected to the pipe wall of the above-mentioned main pipe 61, and the above-mentioned fins 63 are inserted through the above-mentioned heat exchange pipe 62. The heat exchange pipe 62 can export part of the heat of the water flowing in the above-mentioned main pipe 61 and transfer the heat to the above-mentioned fins 63. The fins 63 are heat dissipation fins, such as aluminum sheets, and the air in the air duct 7 can take away the heat on the fins 63. The heat exchange efficiency of the second heat exchange structure 6 is high, and it can well cool the water in the return water pipe 4.

[0061] As another implementation of this embodiment, the second heat exchange structure 6 can also be used to replace the first heat exchange structure 3. When specifically used, the above-mentioned fins 63 can be attached to the outer wall of the compressor.

[0062] Embodiment 4:

[0063] As a specific implementation of Embodiment 3, in this embodiment, a plurality of jacks are provided at intervals on the pipe wall of the above-mentioned straight pipe, and a heat exchange pipe 62 is inserted into each jack, and each heat exchange pipe 62 is inserted into the above-mentioned fins 63. The above-mentioned heat exchange pipe 62 is an L-shaped structure, which includes a short side and a long side. The short side is inserted into the above-mentioned jack, and a second sealing ring is also provided between the jack and the short side to avoid leakage. Preferably, the above-mentioned short side is inserted to the central position of the above-mentioned main pipe 61 to perform good heat exchange with the water in the main pipe 61. The number of the above-mentioned fins 63 is also multiple, and the multiple fins 63 are distributed at intervals to obtain a better air-cooling effect, and further better cool the water in the return water pipe 4.

[0064] As an optimal implementation manner of this embodiment, both ends of the heat exchange tube 62 in this embodiment are closed, that is, a closed cavity is formed inside the heat exchange tube 62, and this cavity is the inner hole of the above-mentioned heat exchange tube 62. A filler 64 made of a phase change material is provided in this cavity. Specifically, the phase change temperature of this phase change material is 40°C - 80°C. For example, this phase change material is paraffin, fatty acids or polyols. The temperature of the phase change material in the heat exchange tube 62 inserted into the above-mentioned main pipe 61 is high. Therefore, after phase change, it flows to the other end inside the heat exchange tube 62 and cools back to its original state. During this process, heat can be absorbed, and part of the heat can be driven to the other end and the above-mentioned fins 63. The air in the air duct 7 can then air-cool the other end of the heat exchange tube 62 and the fins 63.

[0065] Embodiment 5:
