Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a chassis and a dishwasher. Background Technology

[0002] With social development and the improvement of people's living standards, dishwashers are being used more and more widely in daily life. Dishwashers can automatically clean dishes, making life more convenient.

[0003] The chassis of a dishwasher is usually equipped with an electrical control box, which contains a wiring harness connector for electrical connection to the power cord. To prevent the wiring harness connector from swinging during transportation, it is usually placed inside the electrical control box. When connecting the wiring harness connector to the power cord, the installer needs to use a screwdriver or other tools to open the electrical control box, remove the wiring harness connector from the box, and then connect it to the power cord, which makes the connection between the wiring harness connector and the power cord inconvenient. Utility Model Content

[0004] This application provides a chassis and a dishwasher. When connecting the wiring harness connector to the power cord, the user can directly connect the connector part of the wiring harness connector to the power cord by hand without using tools such as screwdrivers to open the electrical control box. This reduces installation steps and makes the connection between the wiring harness connector and the power cord more convenient.

[0005] In a first aspect, this application provides a chassis, comprising:

[0006] Disk body;

[0007] An electrical control box is mounted on the chassis, and an electrical control component is installed in the electrical control box;

[0008] A wiring harness connector, which is electrically connected to the electronic control component; and...

[0009] A limiting structure is provided on the disk body, and the limiting structure is used to connect with the wire harness connector to fix the wire harness connector to the disk body.

[0010] In some embodiments of this application, the limiting structure includes at least one of a slot, a buckle, and a magnetic component; wherein, the slot is disposed on the disk body, and the slot is used for inserting and engaging the wire harness connector to fix the wire harness connector to the disk body; the buckle is used for engaging with the wire harness connector to fix the wire harness connector to the disk body; the magnetic component is disposed on the disk body, and the magnetic component is used for magnetically connecting with the wire harness connector to fix the wire harness connector to the disk body. This makes the fixing method of the wire harness connector relatively simple, and it is also more convenient for the user to take out and put away the wire harness connector, thus making it more convenient.

[0011] In some embodiments of this application, the disk body includes: a base plate; and peripheral side plates disposed around the base plate to form a receiving cavity with the base plate; wherein the electrical control box is disposed on the outer side of the peripheral side plates. This makes it more convenient for the user to operate the electrical control box, and the wiring harness connector is also located outside the receiving cavity, making it more convenient for the user to connect the wiring harness connector to the power cord.

[0012] In some embodiments of this application, the limiting structure includes a first slot disposed on the peripheral side plate. The first slot extends from the outer side of the peripheral side plate toward the receiving cavity to penetrate the peripheral side plate, and extends upward to penetrate the top of the peripheral side plate to form a latch for the wire harness connector to be engaged in the first slot. After the wire harness connector moves above the latch, moving the wire harness connector downward causes it to be engaged in the first slot through the latch. To remove the wire harness connector, pulling it upward removes it from the latch, thus making it easier to pick up and put away the wire harness connector.

[0013] In some embodiments of this application, a guide slope is provided on the peripheral side plate, the guide slope extending downward from the top surface of the peripheral side plate to the groove wall of the first slot. When the wire harness connector moves downward and is inserted into the first slot, the wire harness connector may first contact the guide slope, the guide slope can provide guidance for the wire harness connector, so that the wire harness connector can be inserted into the first slot more smoothly along the guide slope.

[0014] In some embodiments of this application, the limiting structure further includes a second slot, which is located below and communicates with the first slot. The length of the second slot along the width direction of the first slot is greater than the width of the first slot. When there are many conductive connecting wires in the wire harness connector, the conductive connecting wires can be sequentially passed through the first slot into the second slot. The second slot provides constraint and fixation for the wire harness connector, thereby meeting the limiting requirements of more wire harness connectors of different specifications.

[0015] In some embodiments of this application, a mounting groove is provided on the outer surface of the peripheral side plate, and at least a portion of the electrical control box is accommodated in the mounting groove. The mounting groove can be used to provide space for the electrical control box, thereby reducing the overall volume of the chassis.

[0016] In some embodiments of this application, the limiting structure is disposed on the wall of the mounting groove. This makes the limiting structure closer to the mounting groove, thus allowing the wire harness connector to still be connected to the limiting structure even when the wire harness connector is short.

[0017] In some embodiments of this application, the chassis further includes multiple support feet, and the receiving cavity is provided with support columns corresponding to and connected to each support foot. Among the multiple support columns, the support column closest to the electrical control box is the first support column, and the limiting structure is located between the electrical control box and the first support column. The limiting structure can also be located near the corner of the chassis, so that when the limiting structure fixes the wire harness connector, the wire harness connector can avoid the middle area of ​​the receiving cavity.

[0018] Secondly, this application also provides a dishwasher, including an inner tub and a chassis as described in any of the above embodiments, wherein the inner tub is located above the chassis and connected to the chassis.

[0019] The beneficial effects of this application are as follows: By setting a limiting structure on the chassis to constrain and fix the wire harness connector, production line workers can place the end of the wire harness connector with the connector portion outside the electrical control box after the chassis is manufactured, and use the limiting structure to fix the wire harness connector to the chassis. This can prevent the wire harness connector from swinging during transportation. When connecting the wire harness connector to the power cord, users can directly connect the connector portion of the wire harness connector to the power cord by hand without using tools such as screwdrivers to open the electrical control box. This reduces installation steps, makes the connection between the wire harness connector and the power cord more convenient, and improves installation efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] This application provides a chassis and a dishwasher to solve the problem in the related art where, when connecting the wiring harness connector to the power cord, the installer needs to use a screwdriver or other tools to open the electrical control box, remove the wiring harness connector from the electrical control box, and then connect it to the power cord, which makes the connection between the wiring harness connector and the power cord inconvenient.

[0030] Firstly, this application provides a chassis, such as Figures 1 to 3 As shown, the chassis includes a chassis body 10, an electrical control box 20, a wiring harness connector 30, and a limiting structure 40.

[0031] The disk body 10 is the main structure of the chassis. The disk body 10 is used to provide support and installation space for devices such as the electrical control box 20. The disk body 10 can be roughly cylindrical, square, or other shapes. This application does not impose any specific restrictions.

[0032] The control box 20 is mounted on the chassis. The control box 20 contains an electrical control component (not shown in the figure). The control box 20 can be generally cylindrical, square, or other shapes. This application does not impose any specific limitations. The control box 20 is used to provide housing space and protection for the electrical control component. The electrical control component is used in electrical appliances (such as dishwashers) to control the opening and closing of the electrical appliances, realize circuit protection and circuit monitoring functions, and improve the safety and reliability of the electrical appliances. The electrical control component may include an electrical control board, which is a circuit board integrating multiple electronic components. The circuit board can be a single-sided board, a double-sided board, or a multi-layer board. This application does not impose any specific limitations on the type, model, and size of the circuit board.

[0033] The wire harness connector 30 is electrically connected to the electronic control component. The wire harness connector 30 is used to electrically connect to the power line, thereby realizing the connection between the electronic control component and the power grid, and thus realizing the connection between the electrical equipment and the power grid. The wire harness connector 30 can be formed by one or more conductive connecting wires.

[0034] A limiting structure 40 is provided on the disk body 10. The limiting structure 40 is used to connect with the wire harness connector 30 to fix the wire harness connector 30 to the disk body 10.

[0035] Understandably, in this application, by providing a limiting structure 40 on the chassis 10 to constrain and fix the wire harness connector 30, production line workers can place one end of the wire harness connector 30 with the connector portion outside the electrical control box 20 after the chassis is manufactured, and use the limiting structure 40 to fix the wire harness connector 30 to the chassis 10. This can prevent the wire harness connector 30 from swinging during transportation. When connecting the wire harness connector 30 to the power cord, users can directly connect the connector portion of the wire harness connector 30 to the power cord by hand without using tools such as screwdrivers to open the electrical control box 20. This reduces installation steps, makes the connection between the wire harness connector 30 and the power cord more convenient, and improves installation efficiency.

[0036] In some embodiments of this application, the limiting structure 40 includes at least one of a slot, a buckle, and a magnetic element; the slot is disposed on the disk body 10 and is used for inserting and engaging the wire harness connector 30 to fix the wire harness connector 30 to the disk body 10; the buckle is used for engaging with the wire harness connector 30 to fix the wire harness connector 30 to the disk body 10; the magnetic element is disposed on the disk body 10 and is used for magnetically connecting with the wire harness connector 30 to fix the wire harness connector 30 to the disk body 10, making the fixing of the wire harness connector 30 relatively simple and convenient for the user to take out the wire harness connector 30, thereby making it more convenient to take out and put away the wire harness connector 30.

[0037] Understandably, when the limiting structure 40 includes a slot, the wire harness connector 30 can be inserted into the slot to fix the wire harness connector 30. When it is necessary to connect the wire harness connector 30 to the power cord, the wire harness connector 30 can be removed from the slot, making the connection between the wire harness connector 30 and the power cord more convenient. When the limiting structure 40 includes a buckle, the buckle can be fixed to the disk body 10. The buckle is provided with an arc-shaped groove, and the wire harness connector 30 can be snapped into the arc-shaped groove to fix it to the disk body 10. Of course, the buckle can also be detachably connected to the disk body 10. The buckle and the disk body 10 can form a limiting hole for the wire harness connector 30 to pass through, thereby fixing the wire harness connector 30 to the disk body 10. When the limiting structure 40 includes a magnetic component, the magnetic component can be directly magnetically connected to the wire harness connector 30, or the magnetic component can be magnetically connected to magnets or other devices on the wire harness connector 30. Among them, multiple fixing methods can be used individually or simultaneously. That is, the wire harness connector 30 can be fixed by the slot, buckle or magnetic component alone, or the slot, buckle or magnetic component can be used to fix the wire harness connector 30 at the same time.

[0038] In some embodiments, the disk body 10 includes a base plate 11 and a peripheral side plate 12 disposed around the base plate 11. The peripheral side plate 12 and the base plate 11 form a receiving cavity 13. The control box 20 is disposed outside the peripheral side plate 12, and the limiting structure 40 is disposed on the peripheral side plate 12. It can be understood that, compared to placing the control box 20 in the receiving cavity 13, this embodiment places the control box 20 outside the receiving cavity 13, making it more convenient for the user to operate the control box 20. Furthermore, the wiring harness connector 30 is also located outside the receiving cavity 13, making it more convenient for the user to connect the wiring harness connector 30 to the power cord.

[0039] The peripheral side panel 12 may include multiple side panels, each corresponding to a side edge of the base plate 11. The heights of the multiple side panels may be the same or different. The top of the tray body 10 may be open. Taking the tray as an example of a dishwasher, the inner tank 60 of the dishwasher (e.g.) Figure 5 The inner liner 60 can be supported by the chassis by inserting it into the receiving cavity 13 through the opening and connecting it to the peripheral side plate 12.

[0040] See also Figures 1 to 3 As shown, in some embodiments, the limiting structure 40 includes a first slot 41 disposed on the peripheral side plate 12. The first slot 41 extends from the outer side of the peripheral side plate 12 toward the receiving cavity 13 to penetrate the peripheral side plate 12, and the first slot 41 extends upward and penetrates the top end of the peripheral side plate 12 to form a slot 411 for the wire harness connector 30 to be inserted into the first slot 41. It should be noted that the first slot 411 faces upwards, so that after the wire harness connector 30 moves above the slot 411, it moves downwards so that the wire harness connector 30 passes through the slot 411 and is inserted into the first slot 41. To remove the wire harness connector 30, simply pull it upwards to remove it from the slot 411, making it easier to pick up and put down the wire harness connector 30. In addition, the first slot 41 is connected to the receiving cavity 13, so that when the wire harness connector 30 is inserted into the first slot 41, the connector part of the wire harness connector 30 can be hidden in the receiving cavity 13, preventing the connector part of the wire harness connector 30 from being damaged during transportation.

[0041] In some embodiments, a guide slope 43 is provided on the peripheral side plate 12. The guide slope 43 extends downward from the top surface of the peripheral side plate 12 to the groove wall of the first slot 41, so that when the wire harness connector 30 moves downward to insert into the first slot 41, the wire harness connector 30 can first contact the guide slope 43. The guide slope 43 can provide guidance for the wire harness connector 30, so that the wire harness connector 30 can be inserted into the first slot 41 more smoothly along the guide slope 43.

[0042] In some embodiments, the limiting structure 40 further includes a second slot 42, which is located below and communicates with the first slot 41. The length of the second slot 42 along the width direction of the first slot 41 is greater than the width of the first slot 41. It should be noted that the second slot 42 is connected to the bottom of the first slot 41 to form a roughly "⊥" shaped slot structure. The width direction of the first slot 41 is the arrangement direction of the two slot walls of the first slot 41 (i.e.,...). Figure 3 In the XX direction, the width of the first slot 41 is parallel to the horizontal direction. The width of the first slot 41 is relatively small. When the number of conductive connecting wires in the wire harness connector 30 is small, all conductive connecting parts can be locked in the first slot 41. When the number of conductive connecting wires in the wire harness connector 30 is large, the conductive connecting wires can pass through the first slot 41 into the second slot 42 in sequence. The second slot 42 provides constraint and fixation for the wire harness connector 30, thereby meeting the limiting requirements of more different specifications of wire harness connector 30. In addition, considering the possibility of drops and vibrations during the transportation of the chassis, the second slot 42 can also provide upward limiting for the wire harness connector 30, making it less likely for the wire harness connector 30 to loosen.

[0043] In some embodiments, a mounting groove 121 is provided on the outer side surface of the peripheral side plate 12, and at least a portion of the electrical control box 20 is accommodated in the mounting groove 121. The mounting groove 121 can be used to provide accommodating space for the electrical control box 20, thereby reducing the overall volume of the chassis.

[0044] The limiting structure 40 can be set on the wall of the mounting groove 121 so that the distance between the limiting structure 40 and the mounting groove 121 is relatively close, so that the wire harness connector 30 can still be connected to the limiting structure 40 even when the wire harness connector 30 is relatively short.

[0045] In some embodiments, the chassis further includes multiple support feet (not shown in the figure). The receiving cavity 13 is provided with support columns 50 that correspond one-to-one with and are connected to the support feet. Among the multiple support columns 50, the support column 50 closest to the control box 20 is the first support column 50. The limiting structure 40 is located between the control box 20 and the first support column 50. It should be noted that the support feet can adjust the distance between the chassis and the ground, thereby adjusting the placement height of the chassis. Two, three, four, or more support feet can be provided. The number of support columns 50 is the same as the number of support feet. The support feet are located at the corners of the chassis 10, so that the support columns 50 are also located at the corners of the chassis 10. The limiting structure 40 is located between the control box 20 and the first support column 50. Alternatively, the limiting structure 40 can also be located close to the corners of the chassis 10, so that when the limiting structure 40 fixes the wire harness connector 30, the wire harness connector... The head 30 can avoid the middle area of ​​the receiving cavity 13 (the middle area is generally used to place electronic components such as the drive architecture), thereby preventing the wire harness connector 30 from short-circuiting with the electronic components in the receiving cavity 13; in addition, the first support post 50 is the support post 50 closest to the control box 20, and the limiting structure 40 is set between the control box 20 and the first support post 50, so that the limiting structure 40 can be closer to the control box 20, and thus the wire harness connector 30 can still be connected to the limiting structure 40 even when the wire harness connector 30 is short.

[0046] like Figure 4 As shown, in some embodiments, the electrical control box 20 is provided with a wire passage hole 21 for the wire harness connector 30 to pass through, and the wire passage hole 21 is located at the bottom of the electrical control box 20. It can be understood that one end of the wire harness connector 30 with the connector portion can pass through the wire passage hole 21 to exit from the electrical control box 20. By placing the wire passage hole 21 at the bottom of the electrical control box 20, it is possible to prevent water, dust, and other dirt from entering the electrical control box 20 through the wire passage hole 21.

[0047] Secondly, this application also provides a dishwasher, such as Figure 5 As shown, the dishwasher includes an inner tub 60 and a chassis as described in any of the above embodiments, with the inner tub 60 located above and connected to the chassis.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
