[0022] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0023] The utility model discloses an electrical appliance base for screwless assembly of a power box, aiming to realize screwless assembly of the power box to improve assembly efficiency and facilitate subsequent disassembly and maintenance.

[0024] like Figure 1 As shown, the electrical appliance base includes a bottom cover 1, which is the lower end part of the electrical appliance base. The bottom cover 1 is provided with a top rod 11, and the top rod 11 has a limiting hole 111.

[0025] like Figure 2 As shown, the electrical appliance base also includes a seat body 2, which is fixedly assembled on the bottom cover 1 through a detachable structure. The inner wall of the seat body 2 is provided with an assembly boss 21, and the lower side of the assembly boss 21 is provided with an assembly position 22, and the assembly position 22 is provided with a positioning column 23 extending downward; the positioning column 23 is arranged one-to-one with the top rod 11.

[0026] like Figure 3 and Figure 4 The electrical appliance base also includes a power box 3. The power box 3 includes a box body 31, a limit sleeve 32, and a connecting arm 33 connected between the box body 31 and the limit sleeve 32. A mounting groove 311 is provided on one side of the box body 31, and the mounting groove 311 is used to fix and assemble the power circuit board.

[0027] Further integration Figure 5 As shown, the power box 3 is sleeved on the positioning column 23 through the limiting sleeve 32 .

[0028] Further integration Figure 6 As shown, the bottom cover 1 is fixedly assembled with the seat body 2 through a detachable structure. At this time, the upper end of the push rod 11 abuts against the limiting sleeve 32, and the push rod 11 provides support from bottom to top, pressing and fixing the limiting sleeve 32 in the assembly position 22.

[0029] It can be seen that in the electrical base disclosed by the utility model, the power box 3 is horizontally limited by the limit sleeve 3 and the positioning column 23 of the base body 2. When the bottom cover 1 and the base body 2 are fixedly assembled by the detachable structure, the upper end of the top rod 11 of the bottom cover 1 is abutted against the limit sleeve 32 from bottom to top, so that the top rod 11 provides longitudinal limitation for the limit sleeve 3 to press and fix the limit sleeve 32 on the assembly position 22, so that the power box 3 is pressed and assembled between the bottom cover 1 and the base body 2 without using screws to lock the power box 3, thereby simplifying the assembly structure of the power box 3, improving the production and assembly efficiency of the electrical base, and facilitating subsequent disassembly and maintenance.

[0030] When the manufacturer assembles the electrical base, first Figure 2 As shown, the seat body 2 is turned upside down so that the positioning column 23 faces upward, and then the limiting sleeve 32 of the power box 3 is inserted into the positioning column 23, and then the bottom cover 1 is turned upside down on the seat body 2 and fixedly assembled using the detachable structure. At this time, the top rod 11 abuts against the limiting sleeve 32 to press the limiting sleeve 32 onto the assembly position 22, and the assembly of the appliance base is completed. The entire assembly operation is very simple.

[0031] The end of the push rod 11 can directly abut against the surface of the limiting sleeve 32, and the end of the push rod 11 can also cooperate with the end of the positioning column 23 to improve the firmness of the overall structure. In some preferred embodiments, the longitudinal height of the positioning column 23 is greater than the longitudinal length of the limiting sleeve 32, and the lower end of the positioning column 23 extends out of the limiting sleeve 32; the upper end of the push rod 11 is coupled to the lower end of the positioning column 23, and the upper end surface of the push rod 11 abuts against the limiting sleeve 32.

[0032] The upper end of the push rod 11 is coupled with the lower end of the positioning column 23, and the positioning column 23 limits the push rod 11 laterally to ensure that the upper end surface of the push rod 11 is firmly in contact with the limiting sleeve 32, and will not move to affect the assembly firmness of the power box 3.

[0033] For example, the push rod 11 has a limiting hole 111, and the upper end of the push rod 11 is inserted into the limiting hole 111 for limiting cooperation.

[0034] There is even an elastic member between the push rod 11 and the limiting sleeve 32. The elastic member can be a spring or a spring sheet. The upper end surface of the push rod 11 is elastically abutted against the limiting sleeve 32 through the elastic member, thereby further improving the firmness of the abutment between the upper end surface of the push rod 11 and the limiting sleeve 32.

[0035] Since the overall weight of the power box 3 is applied to the positioning column 23 through the limiting sleeve 32 , in order to increase the rigidity of the positioning column 23 and prevent it from being deformed, a plurality of reinforcing ribs 24 are provided at the connection between the positioning column 23 and the assembly boss 21 .

[0036] There are at least two positioning posts 23 , and at least two spaced positioning posts 23 are matched with at least two limiting sleeves 32 , respectively, which is beneficial to improving the assembly firmness of the power box 3 between the bottom cover 1 and the base 2 .

[0037] In addition, the assembly boss 21 is further provided with a wiring hole 29 , and the wiring hole 29 is located between two of the positioning posts 23 .

[0038] Especially see Figure 6 As shown, the angle between the box body 31 and the connecting arm 33 is greater than 90° so that the box body 31 is tilted downward, and the mounting groove 311 is located on the lower side of the box body 31. The advantages of such a structure are: first, the power circuit board installed in the mounting groove 311 is close to the bottom cover 1 and away from the base 2, which can reduce the influence of other components (such as a heater) installed in the base 2 on the power circuit board, which is conducive to improving the working stability of the power circuit board; second, the box body 31 is tilted downward and the mounting groove 311 is located on the lower side of the box body 31. In the event of water leakage during the use of the electrical base, the leaked water will drip on the upper side of the box body 31 and divert downward, and will not flow into the mounting groove 311 to cause damage to the power circuit board.

[0039] The detachable structure includes: a plurality of upper studs 28 arranged around the inner wall of the seat body 2, and a plurality of lower studs 12 arranged around the bottom cover 1. The upper studs 28 abut against the lower studs 12 and are locked by fixing members (such as screws).

[0040] Furthermore, a plurality of supporting ribs 13 are provided on the periphery of the inner wall of the bottom cover 1, and the side of the supporting rib 13 has an abutment position 131 extending from the bottom cover 1, and the lower end of the base body 2 abuts against the abutment position 131 to improve the rigidity strength of the assembly structure of the bottom cover 1 and the base body 1, so that the overall structure of the electrical appliance base is reliable and not prone to deformation.

[0041] The utility model discloses an electric rice cooker having the above-mentioned electric appliance base. Specifically, an electric heating element and a cooking pot are arranged in the base body 2, and a pot cover that can be covered on the electric appliance base. The electric heating element is electrically connected to a power supply circuit board fixed in a mounting groove 311 of a power supply box 3, and the electric heating element heats the cooking pot for cooking.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
