For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Dehumidifiers are used to adjust air humidity so that it is maintained within a comfortable humidity range. The air generated during the operation of the dehumidifier can be discharged through a water pump installed inside the dehumidifier. However, the water pump of the existing dehumidifier has poor waterproof performance, and water leakage may occur during operation. In addition, the noise generated during the operation of the water pump is relatively large, thus affecting the user's comfort.

[0041] Based on the above questions, please refer to Figures 1 to 5The present invention provides a dehumidifier 10, including a water pump assembly 100, a middle partition 200, a water tank 300, a compressor 400, a housing 500, a condenser 600, an evaporator 700 and a throttle (not shown).

[0042] Among them, the shell 500 is arranged around the outside of the water pump assembly 100, the middle partition 200, the water tank 300, the compressor 400, the condenser 600, the evaporator 700 and the throttle, and the condenser 600 and the evaporator 700 are located in the upper part of the internal space of the shell 500, the water tank 300, the water pump assembly 100 and the compressor 400 are located in the lower part of the internal space of the shell 500, the middle partition 200 is arranged on one side of the water tank 300, the water pump assembly 100 is installed on the middle partition 200, the pipe 130 of the water pump assembly is connected to the water tank 300, the water tank 300 is used to receive the water droplets generated during the dehumidification process, and the water pump assembly 100 is used to discharge the water in the water tank 300.

[0043] It is understandable that the dehumidifier 10 is also provided with a heat exchange medium, which can be, but is not limited to, a refrigerant. The heat exchange medium first flows to the condenser 600 in a high-temperature and high-pressure state under the compression of the compressor 400, and the high-temperature and high-pressure heat exchange medium is cooled down to form a low-temperature and high-pressure liquid under the action of the condenser 600, and then passes through the throttling device to form a low-temperature and low-pressure liquid. The heat exchange medium then flows to the evaporator 700, and the low-temperature and low-pressure liquid heat exchange medium transfers heat with the air in the evaporator 700, that is, the heat exchange medium absorbs heat to condense the moisture in the air, thereby achieving the purpose of dehumidification. In this process, the heat exchange medium is converted from liquid to low-pressure gas and flows to the compressor 400 again, and circulates through the above-mentioned path.

[0044] Furthermore, the water pump assembly 100 includes a mounting seat 110, a pump body 120, a pipe 130, a first buffer member 140 and a shell 150; the pump body 120 is installed on the mounting seat 110, one end of the pipe 130 is connected to the pump body 120, and the other end is connected to the water tank 300, the first buffer member 140 is sleeved on the pipe 130 and abuts against the pump body 120, the shell 150 is covered outside the pump body 120 and at least part of the first buffer member 140, the shell 150 is used to press the first buffer member 140, the shell 150 is fixedly connected to the mounting seat 110, and the mounting seat 110 is installed on the middle partition 200.

[0045] In this embodiment, the number of pipes 130 includes two, and the two pipes 130 are respectively connected to the two ends of the pump body 120, and one of the pipes 130 is connected to the water tank 300, and the other pipe 130 is used to discharge water from the dehumidifier 10; therefore, the number of first buffer members 140 also includes two, and the two first buffer members 140 are respectively mounted on the two pipes 130, and respectively abut against the upper and lower ends of the pump body 120.

[0046] By sleeved the first buffer component 140 on the pipe 130 connected to the pump body 120 and making the first buffer component 140 abut against the pump body 120, it can effectively play a buffering role during the operation of the pump body 120, achieve the purpose of waterproofing, and also play a role in silencing and reducing noise; on this basis, the shell 150 is covered outside the pump body 120 to further reduce the noise of the water pump operation, thereby achieving good sound insulation and noise reduction effects, and improving the user's comfort.

[0047] In addition, compared with the existing water pump, the pressure climb is eliminated, and the housing 150 is directly pressed against the first buffer member 140, which makes the assembly more convenient and simple, improves the assembly efficiency, and reduces the production cost.

[0048] Optionally, the first buffer member 140 is made of rubber material, which can provide a better buffering effect.

[0049] Furthermore, the mounting seat 110 is provided with two limiting portions 111 , the pump body 120 and the first buffer member 140 are both provided between the two limiting portions 111 , and the limiting portion 111 is used to abut against the first buffer member 140 .

[0050] In this embodiment, one side of the first buffer component 140 abuts against the pump body 120, and the other side abuts against one of the limiting portions 111. In other words, the first buffer component 140, the pump body 120 and another first buffer component 140 are arranged in sequence, and the two first buffer components 140 abut against the two limiting portions 111 respectively, so as to play a limiting role through the limiting portions 111, and then the first buffer component 140 is pressed by the shell 150, so as to realize that the first buffer component 140 is tightly abutted against the pump body 120, thereby ensuring that the first buffer component 140 plays a good buffering role.

[0051] Furthermore, the first buffer member 140 includes a sleeve portion 141 and a supporting portion 142 which are connected to each other. The sleeve portion 141 is sleeved on the pipeline 130 , and the supporting portion 142 is in contact with the pump body 120 .

[0052] In this embodiment, the sleeve portion 141 is cylindrical and has a hole in the middle for the pipe 130 to pass through; the supporting portion 142 is connected to one end of the sleeve portion 141 and is in the shape of a rectangular plate, and the plane where the supporting portion 142 is located is perpendicular to the axis of the sleeve portion 141.

[0053] Therefore, by sleeve-fitting the sleeve portion 141 outside the pipe 130, the pipe 130 can be fixed so that the pipe 130 is stably connected to the pump body 120; and by abutting the abutting portion connected to one end of the sleeve portion 141 against the pump body 120, it can effectively play a role of buffering and shock absorption, thereby significantly playing a role of silencing and reducing noise.

[0054] Furthermore, a plurality of ribs 143 disposed at intervals are protruded from one side of the abutting portion 142 facing the pump body 120 , and the ribs 143 are used to abut against the pump body 120 to further enhance the buffering and shock absorbing effect generated when the abutting portion 142 abuts against the pump body 120 .

[0055] In this embodiment, a connecting portion 144 is further disposed between two adjacent ribs 143 , and two ends of the connecting portion 144 are respectively connected to the two ribs 143 , so as to improve the structural strength of the abutting portion.

[0056] Furthermore, the limiting portion 111 is provided with a first avoidance opening 112, the two sides of the shell 150 are respectively covered on the two limiting portions 111, and the side walls corresponding to the limiting portions 111 are provided with a second avoidance opening 151, so that the first avoidance opening 112 and the second avoidance opening 151 are correspondingly arranged, and the sleeve portion 141 is arranged between the first avoidance opening 112 and the second avoidance opening 151.

[0057] In this embodiment, since the sleeve portion 141 is cylindrical, the first escape opening 112 and the second escape opening 151 are both semicircular arc-shaped to form a circular shape. Therefore, when the housing 150 is sleeved outside the pump body 120 and pressed against the abutment portion, the sleeve portion 141 is arranged between the first escape opening 112 and the second escape opening 151, which can improve the installation stability of the first buffer member 140. At the same time, the edge of the housing 150 corresponding to the second escape opening 151 can also play a certain pressing and holding role on the sleeve portion 141.

[0058] Furthermore, the mounting seat 110 defines a first mounting hole 113 , and the housing 150 defines a second mounting hole 152 . The first mounting hole 113 and the second mounting hole 152 are correspondingly arranged.

[0059] In this embodiment, the side wall of the housing 150 provided with the second avoidance opening 151 is also provided with a folded edge perpendicular to the side wall, and the second mounting hole 152 is opened on the folded edge. By sequentially passing the fastener (not shown) through the second mounting hole 152 and the first mounting hole 113 and fixedly matching with the first mounting hole 113, the installation is convenient, and the housing 150 can be firmly fixed on the limiting portion 111, so that the housing 150 can tightly press the first buffer 140, so that the first buffer 140 can effectively play a buffering and shock absorbing role.

[0060] Specifically, the first mounting hole 113 is arranged on the limiting portion 111 and is located on both sides of the first avoidance opening 112. The second mounting hole 152 is located on both sides of the second avoidance opening 151. Two first mounting holes 113 are arranged on one limiting portion 111. Correspondingly, two second mounting holes 152 are arranged on one side wall of the shell 150.

[0061] Furthermore, a buckle 114 is provided on the side of the mounting seat 110 , and a locking hole 153 is provided on the housing 150 , and the buckle 114 is engaged with the locking hole 153 .

[0062] In this embodiment, two opposite side walls of the housing 150 are provided with a second avoidance opening 151 and a second mounting hole 152, and the other two opposite side walls are provided with a clamping hole 153. When the housing 150 is covered outside the pump body 120, the cover body can be clamped on the mounting seat 110 through the clamping cooperation of the buckle 114 and the clamping hole 153, making it more convenient to install or remove the cover body, thereby improving the installation efficiency.

[0063] After the buckle 114 is locked and matched with the locking hole 153 , the first mounting hole 113 and the second mounting hole 152 are penetrated by fasteners to further improve the installation stability of the housing 150 .

[0064] Furthermore, the water pump assembly 100 further includes a second buffer member 160 . The mounting seat 110 is provided with a mounting portion 115 , and the second buffer member 160 is disposed on the mounting portion 115 .

[0065] In this embodiment, the mounting portion 115 is U-shaped, so that the mounting base 110 can be installed on the middle partition 200 by fasteners; and a second buffer member 160 is arranged on the mounting portion 115, which can further reduce the vibration transmitted from the pump body 120 to the mounting base 110 during the operation of the pump body 120, thereby further achieving the effect of shock absorption and noise reduction of the water pump assembly 100.

[0066] Specifically, there are two mounting portions 115 , which are respectively located at the upper and lower sides of the mounting seat 110 . Therefore, there are also two second buffer members 160 , which can also be made of rubber.

[0067] It should be noted that two mounting columns 210 corresponding to the two mounting portions 115 are protruded from the middle partition 200. During the installation process, the mounting columns 210 are inserted into the U-shaped mounting portions 115 and fixed by fasteners so that the mounting columns 210 are firmly mounted on the middle partition 200.

[0068] Furthermore, the mounting portion 115 is arranged on the side of the mounting seat 110, the shape of the second buffer member 160 matches the shape of the mounting portion 115, and the second buffer member 160 is provided with a slot 161, and the edge of the mounting portion 115 is embedded in the slot 161, so that the second buffer member 160 can be firmly installed on the mounting portion 115, thereby improving the installation stability of the mounting seat 110.

[0069] Specifically, a positioning portion 116 is further provided on the other side of the mounting seat 110, and the positioning portion 116 is also U-shaped. The middle partition 200 is also protruding with a positioning column 220, so that the positioning column 220 can be inserted into the U-shaped positioning portion 116 for positioning, thereby ensuring the installation accuracy of the mounting seat 110.

[0070] In summary, the present invention provides a water pump assembly 100 and a dehumidifier 10. By sleeve-mounting the first buffer 140 on the pipe 130 connected to the pump body 120 and making the first buffer 140 abut against the pump body 120, it can effectively play a buffering role during the operation of the pump body 120, and achieve the purpose of waterproofing, and also play a role in silencing and reducing noise; on this basis, the shell 150 is covered outside the pump body 120 to further reduce the noise of the water pump operation, thereby achieving good sound insulation and noise reduction effects, and improving the user's comfort. In addition, compared with the existing water pump, the pressure climbing is cancelled, and the shell 150 is directly pressed against the first buffer 140, which can make the assembly more convenient and simple, improve the assembly efficiency, and reduce the production cost.
