DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0021] like Figures 1 to 4As shown, the utility model provides a high-power dishwasher power supply structure, including a housing 1, a power module 2, a heat dissipation hole 11 and a heat dissipation module 3, all of which are arranged in the housing 1. The heat dissipation module 3 includes a fan 31, a partition 33 and a plurality of heat dissipation fins 34. The partition 33 is located inside the housing 1 and divides the interior of the housing 1 into two areas. The power module 2 is located in one area inside the housing 1.

[0022] The heat dissipation holes 11 and the fan 31 are both arranged in another area inside the shell 1 and the fan 31 is electrically connected to the power module 2. A number of heat dissipation fins 34 are arranged on the heat dissipation plate 32 and facing the fan 31; the power module 2 includes a first circuit board 21 and a number of electronic components 22 electrically connected to the first circuit board 21, and the electronic components 22 are arranged on the partition 33.

[0023] Specifically, some electronic components 22 and heat sink fins 34 of the power module 2 are directly attached to the partition 33, so that the heat generated by the electronic components 22 is promptly transferred to the heat sink fins 34 by the partition 33. The fan 31 blows air to achieve rapid flow of air inside the housing 1, thereby achieving the effect of timely heat dissipation. Preferably, the electronic component 22 is a power tube.

[0024] In this embodiment, the heat dissipation module 3 also includes a heat dissipation plate 32, which is installed on one end surface of the partition 33 close to the fan 31. The partition 33 is provided with a clearance hole 36. The electronic component 22 passes through the clearance hole 36 and is fixed to the end surface of the heat dissipation plate 32 away from the fan 31, so that the heat generated by the electronic component 22 can be promptly transferred to the heat dissipation fins 34 through the heat dissipation plate 32, thereby improving the heat exchange efficiency; in addition, some electronic components 22 with low heating efficiency exchange heat with the air, and the air can also be transferred to the heat dissipation fins 34 after exchanging heat with the partition 33, thereby achieving the effect of keeping the temperature of these electronic components 22 within a certain range.

[0025] In this embodiment, the power module 2 further includes a second circuit board 23 , and a plurality of support columns 26 are disposed between the second circuit board 23 and the first circuit board 21 .

[0026] The second circuit board 23 is used to mount some electronic components, and the support columns 26 are used to ensure that there is enough space between the first circuit board 21 and the second circuit board 23 for heat dissipation.

[0027] In this embodiment, the power module 2 further includes an energy storage device 24 . The energy storage device 24 is mounted on the first circuit board 21 , and the energy storage device 24 is located on one side of the heat dissipation fins 34 .

[0028] The energy storage device 24 can be a commonly used component such as a capacitor. That is, the utility model divides the interior of the shell 1 into two areas by a partition 33: one area is used to set the electronic components 22, and the other area is used to set the energy storage device 24 and the heat dissipation fins 34 and the fan 31. This ensures that the external air does not directly contact the electronic components 22 to avoid damage to the electronic components 22, and allows the heat dissipation fins 34, the energy storage device 24 and other heat-absorbing and heat-generating components to be located in the same area with the fan 31 to ensure the heat dissipation effect.

[0029] In this embodiment, the housing 1 is provided with a plurality of guide holes 12 on the side away from the fan 31 , a plurality of heat dissipation fins 34 are stacked at intervals, and guide grooves 38 are formed between adjacent heat dissipation fins 34 , and the guide holes 12 are connected to the guide grooves 38 in a one-to-one correspondence.

[0030] That is, the gas in the guide groove 38 enters the housing 1 through the guide hole 12 and is blown to the outside by the fan 31 for heat exchange, thereby further improving the efficiency of heat exchange.

[0031] In this embodiment, the bottom of the housing 1 is provided with a heat dissipation hole 11, which is located below the housing 1 away from the fan 31. Through the heat dissipation hole 11, external air can enter in a variety of ways, further increasing the heat dissipation effect.

[0032] In this embodiment, the first circuit board 21 is provided with a plurality of heat dissipation slots 25. On the one hand, the heat of the first circuit board 21 is allowed to be dissipated more easily. On the other hand, when the first circuit board 21 is heated up and deformed, the heat dissipation slots 25 can compensate for the deformation, thereby avoiding bending deformation caused by internal stress of the first circuit board 21.

[0033] In this embodiment, the housing 1 is provided with a control panel 13 . The control panel 13 is electrically connected to the power module 2 . The control panel 13 and the fan 31 are respectively provided at two ends of the housing 1 .

[0034] In summary, a high-power dishwasher power supply structure in this embodiment divides the interior of the power supply into two areas through a partition 33, one area is installed with the power module 2, and the other area is installed with the heat dissipation module 3; wherein some electronic components 22 of the power module 2 are directly attached to the partition 33, and the partition 33 dissipates heat from the partition 33 through the air duct formed by the heat dissipation holes 11 and the fan 31 in the other area, thereby ensuring that the power module 2 is sealed while effectively dissipating the heat of the power module 2, solving the problem that some sensitive components inside the power supply are easily dusty or damp.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
