Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] The following is combined Figures 1 to 5 The embodiments of this utility model are described below.

[0029] This embodiment relates to a power supply box structure for a dishwasher that provides additional space within the dishwasher for placing a circuit board.

[0030] In this embodiment, a recess 11 is formed on the power box structure of a dishwasher to provide space for the installation of a circuit board, thereby increasing the security of the dishwasher's circuit board. The structure includes: a base frame 1, on the side of which a recess 11 is integrally formed, and the recess 11 is used to install the circuit board.

[0031] The power supply box structure disclosed herein has a space for mounting on the base rack 1 of the dishwasher, in order to better meet the needs of expanding different circuit functions.

[0032] In this embodiment, the structure for fixing the circuit board is as follows: a support post 13 and a positioning post 12 are provided in the groove 11, and a first screw hole 121 is provided on the support post 13. The circuit board to be installed has a pre-set positioning hole 201 and a fixing hole. During installation, the positioning hole 21 on the circuit board is aligned with the positioning post 12, so that the upper end of the positioning post 12 passes into the positioning hole 201 to position the circuit board. Then, the first screw hole 121 is aligned with the fixing hole, and a fastening screw is screwed into the first screw hole 121. The circuit board is pressed tightly onto the support post 13 by the fastening screw, thereby conveniently fixing the circuit board.

[0033] In this embodiment, the enclosure groove 11 of the cover 2 can keep the circuit board placed in the groove 11 in a relatively closed state, so as to better isolate the influence of external moisture.

[0034] The power box structure also includes a cover 2, which is detachably connected to the base frame 1. The cover 2 is used to close the groove 11. The groove 11 has a recess 111 at its opening, which is used to position the cover 2. The cover 2 is located within the recess 111. In this embodiment, the groove 11 extends laterally. After the recess 111 is set, the cover 2 is placed in the recess 111, and the cover 2 is vertically limited by the recess 111. After the cover 2 is placed in the recess 111, it is not easy for it to fall off. The recess 111 on the top side of the groove 11 can quickly and accurately position the cover 2, and after positioning, the cover 2 is not easy to fall off, which facilitates subsequent assembly.

[0035] Specifically, the bottom wall of the sink 111 is provided with a second screw hole 112, and the cover 2 is provided with a positioning hole 21. The base frame 1 and the cover 2 are connected by screws passing through the positioning hole 21 and the second screw hole 112. When the dishwasher is working, the water pump will cause the base frame 1 to vibrate. As the main support frame of the dishwasher, the vibration of the water pump and other working components will be transmitted to the circuit board through the base frame 1. The cover 2 is detachably connected to the base frame 1 by screws, which has the advantages of stable installation and convenient assembly and disassembly.

[0036] To simplify the assembly structure of the lid 2, a limiting slot 113 is provided on the inner side wall of the groove 11, and a snap-fit ​​groove 114 is provided on the inner side of the groove 11. A snap-fit ​​block is provided on the side of the snap-fit ​​groove 114 facing the opening of the groove 11. The lid 2 is provided with a first pin 22 and a second pin 23. The first pin 22 is inserted into the groove 11, and the second pin 23 is inserted into the snap-fit ​​groove 114 and is restricted within the snap-fit ​​groove 114 by the snap-fit ​​block. Before assembling the lid 2, the first pin 22 is first inserted into the limiting slot 113 to prevent the first pin 22 from coming out of the opening of the groove 11. Then, the second pin 23 is aligned with the snap-fit ​​block, and pressure is applied to the second pin 23 to make it pass over the snap-fit ​​block and enter the snap-fit ​​groove 114. This achieves pre-fixation of the lid 2 through the snap-fit ​​groove 114 and the limiting slot 113, so that the lid 2 can be locked with screws later.

[0037] To enhance the pre-fixation of the lid 2 assembly, the first pin 22 includes a first support 221 and a second support 222, both of which are L-shaped and face opposite directions. Both the first support 221 and the second support 222 possess a certain degree of elasticity. Their L-shaped structure allows the first pin 22 to engage with the limiting slot 113 when inserted, increasing the limiting points on the lid 2 and making the pre-fixation of the lid 2 more stable.

[0038] To facilitate the placement of accessories at the bottom of the groove 11, a groove bottom fastener 115 is provided on the inner wall of the groove 11. The groove bottom fastener 115 at the bottom of the groove 11 serves to prevent accessories from falling out of the groove 11. When accessories need to be installed, the groove bottom fastener 115 is pressed into the groove 11 to quickly secure the accessories. The accessories can be flame-retardant plates 3, waterproof plates, shock-absorbing plates, etc.

[0039] In this embodiment, the accessory is a flame-retardant plate 3. The power box structure also includes a flame-retardant plate 3, which is secured in the groove 11 by the bottom fastener 115. By configuring the flame-retardant plate 3, fire safety performance can be improved.

[0040] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
