[0037] This utility model provides a dehumidifier. Figure 1 This is a perspective view of an embodiment of the dehumidifier of this utility model. Figure 2 This is a perspective view of an embodiment of the dehumidifier of this utility model, with some external structures hidden. The dehumidifier 1000 includes a compressor 100 and a chassis assembly 200.

[0038] Figure 3 , Figure 4This is a perspective view and a cross-sectional view of the chassis assembly and compressor in one embodiment of the dehumidifier of this utility model. The compressor 100 includes a compressor body 110 and a plurality of connecting seats 120 arranged along the periphery of the compressor 100, each connecting seat 120 having a connecting hole 121. The compressor 100 is a compressor 100 used for refrigeration.

[0039] Figure 5 This is a perspective view of the chassis assembly in one embodiment of the dehumidifier of this utility model. The chassis assembly 200 includes a chassis 210 and a plurality of connecting bolts 220. The chassis 210 has a compressor mounting area. Each connecting bolt 220 includes an integrally formed fixing part 221 and a connecting part 222. The fixing part 221 is embedded in the compressor mounting area of ​​the chassis 210. The connecting part 222 extends upward relative to the chassis 210. The connecting part 222 can pass through a corresponding connecting hole 121, and the connecting seat 120 is fastened to the connecting bolt 220 by a fastener 900.

[0040] In some embodiments, the connecting portion 222 has a threaded cylindrical structure. In some embodiments, the radial dimension of the fixing portion 221 is larger than the radial dimension of the connecting portion 222. The fastener 900 is, for example, a nut.

[0041] In this embodiment, the compressor 100 includes three connecting seats 120 as an example, and the number of connecting bolts 220 corresponds to the number of connecting seats 120. In other embodiments, the compressor 100 may also include other numbers of connecting seats 120, such as four, five, or six, and the number of connecting bolts 220 corresponds to the number of connecting seats 120.

[0042] According to an embodiment of the present invention, the dehumidifier 1000 has a connecting hole 121 on the connecting seat 120 of the compressor 100. The chassis 210 assembly 200 includes a chassis 210 and a plurality of connecting bolts 220. Each connecting bolt 220 includes an integrally formed fixing part 221 and a connecting part 222. The fixing part 221 is embedded in the compressor mounting area of ​​the chassis 210, and the connecting part 222 extends upward relative to the chassis 210. The connecting part 222 can pass through the corresponding connecting hole 121, and the connecting seat 120 and the connecting bolt 220 are fastened together by fasteners 900. Since the connecting bolt 220 is embedded in the chassis 210, the fit tolerance between the connecting bolt 220 and the chassis 210 can be reduced to a large extent, and the positional accuracy and perpendicularity of the connecting bolt 220 relative to the chassis 210 can be improved. During the vibration of the compressor 100, the vibration collision between the connecting bolt 220 and the chassis 210 is eliminated, thereby reducing the noise caused by vibration and improving the service life and user experience of the dehumidifier 1000.

[0043] In some embodiments, the dehumidifier 1000 further includes a support 300 disposed between the chassis 210 and the compressor 100. Figure 6 , Figure 7 This is a perspective view of the support member at different angles in one embodiment of the dehumidifier of this utility model. In some embodiments, the support member 300 has a first surface S1 and a second surface S2 opposite to each other. The support member 300 includes a first recess 310 and a plurality of through holes 320. The first recess 310 is located on the first surface S1 and is used to support the bottom of the compressor body 110. Each through hole 320 extends from the first surface S1 to the second surface S2. The connecting part 222 can pass through the corresponding through hole 320 and the corresponding connecting hole 121, and the connecting seat 120, the support member 300 and the connecting bolt 220 are fastened together by the fastener 900.

[0044] In some embodiments, the chassis 210 is an injection-molded part, and the support member 300 is a sheet metal part. During operation, the compressor 100 generates circular motion of a certain frequency and amplitude, resulting in vibration at a certain frequency. For example, a common fixed-frequency compressor 100 operates at a frequency of 50Hz. The chassis 210, being an injection-molded part, has a natural frequency of approximately 130Hz. The difference between the natural frequency of the chassis 210 and the operating frequency of the compressor 100 is relatively small; if they are in direct contact, resonance is likely to occur. In the above embodiment, the support member 300 is positioned between the chassis 210 and the compressor 100. The support member 300 is a sheet metal part with a natural frequency of approximately 300Hz. The difference between the natural frequency of the support member 300 and the operating frequency of the compressor 100 is relatively large, thereby significantly reducing the probability of resonance.

[0045] In some embodiments, the shape of the first recess 310 is adapted to the bottom shape of the compressor body 110, so that the compressor body 110 can be stably placed on the support 300.

[0046] like Figure 4 In some embodiments, the dehumidifier 1000 further includes a first foot pad 400. At least a portion of the first foot pad 400 is sandwiched between the first surface S1 and the connecting seat 120, and the connecting portion 222 passes through the first foot pad 400. The first foot pad 400 is, for example, a cylindrical, elastic component. In one example, the first foot pad 400 is a rubber component.

[0047] In the above embodiment, at least a portion of the first foot pad 400 is sandwiched between the first surface S1 and the connecting seat 120, thereby further damping the vibration between the compressor 100 and the support 300, thereby reducing the transmission of vibration and reducing the noise caused by vibration.

[0048] like Figure 6In some embodiments, the first surface S1 is provided with a plurality of second recesses 330, each second recess 330 being arranged around a corresponding through hole 320, and the bottom shape of the first foot pad 400 is adapted to the shape of the second recess 330.

[0049] In the above embodiment, the first surface S1 is provided with a second recess 330, and the bottom shape of the first foot pad 400 is adapted to the shape of the second recess 330, thereby improving the stability of the position of the first foot pad 400 and further reducing the transmission of vibration.

[0050] like Figure 4 In some embodiments, the dehumidifier 1000 further includes a second foot pad 500, which is sandwiched between the second surface S2 and the chassis 210, and a connecting portion 222 passes through the second foot pad 500. The second foot pad 500 is, for example, a cylindrical, elastic component. In one example, the second foot pad 500 is a rubber component.

[0051] In the above embodiment, the second foot pad 500 is sandwiched between the second surface S2 and the chassis 210, thereby further damping the vibration between the chassis 210 and the support 300, further reducing the transmission of vibration, and further reducing the noise caused by vibration.

[0052] like Figure 7 In some embodiments, the second surface S2 is provided with a plurality of flanges 340, each flange 340 surrounding a corresponding through hole 320. For example... Figure 4 In some embodiments, the second foot pad 500 is provided with an annular mounting groove 510, and the flange 340 is inserted into the annular mounting groove 510.

[0053] In the above embodiment, the second surface S2 is provided with a flange 340. The flange 340 cooperates with the second foot pad 500 to improve the stability of the position of the second foot pad 500, thereby further reducing the transmission of vibration.

[0054] like Figure 4 The first foot pad 400 and the second recess 330 have a first fitting gap A1, the bottom of the first foot pad 400 and the connecting part 222 have a second fitting gap A2, the top of the first foot pad 400 and the connecting part 222 have a third fitting gap A3, and the annular mounting groove 510 of the second foot pad 500 and the flange 340 have a fourth fitting gap A4.

[0055] In some embodiments, the fourth fitting gap A4 is smaller than the first fitting gap A1, the first fitting gap A1 is smaller than the second fitting gap A2, and the second fitting gap A2 is smaller than the third fitting gap A3.

[0056] In the above embodiments, there are certain fitting gaps between the components. By setting the dimensions of these fitting gaps to be smaller than the first fitting gap A1, smaller than the second fitting gap A2, and smaller than the third fitting gap A3, the vibration suppression effect can be optimized.

[0057] In some embodiments, the hardness of the second foot pad 500 is greater than that of the first foot pad 400. When the hardness relationship between the second foot pad 500 and the first foot pad 400 is set such that the hardness of the second foot pad 500 is greater than that of the first foot pad 400, the shock absorption effect can be further improved.

[0058] In this embodiment, the dehumidifier 1000 also includes other known components, such as a condenser, evaporator, throttling device, fan, controller, power supply, etc. The above-mentioned components can be arranged in a known manner in the dehumidifier 1000 so that the dehumidifier 1000 can condense the moisture in the air into condensate and collect the condensate.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
