Through the above-mentioned setting, since the axis of the first leg and the second leg have an angle, the power board bracket can have only one mounting direction, that is, the power board bracket will not be installed upside down. Similarly, the sizes of the first leg and the second leg are different, which can also prevent the power board bracket from being installed upside down. Therefore, the technical solution of the present application effectively solves the problem that the power board box in the related art is easily installed upside down.

[0007] Furthermore, the angle a between the axis of the first leg and the axis of the second leg satisfies: 60°≤a<180°.

[0013] Furthermore, the first leg is interference fit with the first concave structure, and / or the second leg is interference fit with the second concave structure. The above arrangement can make the positions of the first leg and the second leg more stable, that is, can improve the stability of the power board bracket.

[0014] Furthermore, the bottom cover is in abutment with the surface of the first leg facing the bottom cover, and the bottom cover is in abutment with the surface of the second leg facing the bottom cover. The bottom cover is in abutment with the first leg and the second leg, that is, the bottom cover can limit the power board bracket, so there is no need to use other structures to fix the power board bracket, thereby reducing the difficulty of assembly.

[0015] According to another aspect of the present invention, a cooking utensil is provided, comprising a base assembly, wherein the base assembly is the above-mentioned base assembly. The power board bracket in the above-mentioned base assembly will not be installed upside down, and the power board bracket can be fixed only by the bottom cover, that is, the power board bracket does not need to be fixed by other structures, so the cooking utensil having the above-mentioned base assembly also has the above-mentioned advantages.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] like Figures 1 to 5 As shown, in this embodiment, the base assembly includes: a base 10, a first connection portion 21, a second connection portion 22, a bottom cover 30, a power board bracket 40 and a power board 50. A mounting opening 11 is provided on the bottom wall of the base 10. The first connection portion 21 and the second connection portion 22 are arranged at intervals at the edge of the mounting opening 11. The bottom cover 30 is detachably mounted at the mounting opening 11. The power board bracket 40 is installed between the base 10 and the bottom cover 30, and includes a bracket body 41 and a first leg 42 and a second leg 43 connected to the bracket body 41. The first leg 42 and the second leg 43 are arranged opposite to each other, the first leg 42 is connected to the first connection portion 21, and the second leg 43 is connected to the second connection portion 22; there is an angle a between the axis of the first leg 42 and the axis of the second leg 43.

[0030] According to the technical solution of this embodiment, a mounting opening 11 is provided on the bottom wall of the base 10, and a first connection portion 21 and a second connection portion 22 are provided at intervals at the edge of the mounting opening 11. The bottom cover 30 is detachably mounted at the mounting opening 11, and a power board bracket 40 is mounted between the base 10 and the bottom cover 30. The power board bracket 40 includes a bracket body 41 and a first leg 42 and a second leg 43 connected to the bracket body 41. The bracket body 41 is used to carry the power board 50. The first leg 42 is connected to the first connection portion 21, and the second leg 43 is connected to the second connection portion 22. The axis of the first leg 42 and the axis of the second leg 43 have an angle a. Through the above-mentioned setting, since the axis of the first leg 42 and the second leg 43 have an angle, the power board bracket 40 can have only one mounting direction, that is, the power board bracket 40 will not be installed upside down. Therefore, the technical solution of this embodiment effectively solves the problem that the power board box in the related art is easy to be installed upside down.

[0031] It should be noted that when the bracket body 41 is a rectangle, the relative arrangement of the first leg 42 and the second leg 43 refers to the arrangement of the first leg 42 and the second leg 43 on two opposite sides of the rectangle. When the bracket body 41 is a polygon, the first leg 42 and the second leg 43 are arranged on two non-adjacent sides. When the bracket body 41 is a circle, the first leg 42 and the second leg 43 are symmetrical with respect to the center of the circle. When the first leg 42 and the second leg 43 are coplanar, the angle a between the axis of the first leg 42 and the axis of the second leg 43 refers to the direct angle, and when the first leg 42 and the second leg 43 are not coplanar, the angle a between the axis of the first leg 42 and the axis of the second leg 43 refers to the angle between the projections on the plane parallel to the bracket body 41.

[0032] In other embodiments, the first leg 42 and the second leg 43 have different sizes. The first leg 42 and the second leg 43 have different sizes, which can also prevent the power board bracket 40 from being installed upside down.

[0033] Of course, the axes of the first leg 42 and the second leg 43 may have an included angle a, and the sizes of the first leg 42 and the second leg 43 may be different.

[0034] It should be noted that the above-mentioned dimensions include dimensions and shapes. Specifically, the above-mentioned dimensions refer to axial dimensions or radial dimensions, including width and thickness. For structures with a circular cross-section, the radial dimension is the diameter.

[0035] Regarding different shapes, for example, the first leg 42 is a square and the second leg 43 is a rectangle, or the first leg 42 is a triangle and the second leg 43 is a square, or the first leg 42 is a square and the second leg 43 is a circle. Of course, the above description is only for example, and other different shapes are also possible.

[0036] like Figure 1 As shown, in this embodiment, the angle a between the axis of the first leg 42 and the axis of the second leg 43 satisfies: 60°≤a<180°. The above angle setting enables the power board bracket 40 to have only one installation direction, that is, the power board bracket 40 will not be installed upside down, and the above setting also makes processing easier. Specifically, in this embodiment, the angle a is 120°.

[0037] like Figure 7 As shown, in this embodiment, the maximum distance between the bracket body 41 and the first leg 42 is between 20 mm and 40 mm. In this way, there is enough space to prevent the power board 50 from being inserted.

[0038] like Figures 2 to 4As shown, in this embodiment, the power board bracket 40 further includes a first extension leg 44 and a second extension leg 45, wherein the first extension leg 44 is connected between the bracket body 41 and the first leg 42, and the second extension leg 45 is connected between the bracket body 41 and the second leg 43. The provision of the first extension leg 44 and the second extension leg 45 can increase the extension length of the first leg 42 and the second leg 43, so that the power board bracket 40 can be more easily connected to the base 10.

[0039] like Figures 2 to 4 As shown, in this embodiment, the first leg 42 and the second leg 43 are symmetrically arranged relative to the center line b of the bracket body 41. The above arrangement can make processing easier.

[0040] like Figure 7 As shown, in this embodiment, the distance between the end of the first leg 42 facing the bracket body 41 and the bottom cover 30 is H1, and the distance between the end of the first leg 42 away from the bracket body 41 and the bottom cover 30 is H2, wherein H1>H2; the distance between the end of the second leg 43 facing the bracket body 41 and the bottom cover 30 is H3, and the distance between the end of the second leg 43 away from the bracket body 41 and the bottom cover 30 is H4, wherein H3>H4. The power board 50 is installed at the bottom of the bracket body 41, and the first leg 42 is tilted relative to the bracket body 41, and the second leg 43 is tilted relative to the bracket body 41, so that there is a gap between the power board 50 and the bottom cover 30. This can prevent interference between the power board 50 and the bottom cover 30.

[0041] At the same time, the above-mentioned spacing meets the national standard requirements for the safety of electrical products, that is, the bottom cover 30 is a plastic part, and the power board 50 is an electronic device. Electronic devices have the probability of short circuiting and generating high heat or sparks, which requires sufficient spacing between the electronic devices and the plastic combustible parts.

[0042] like Figure 3 , Figure 4 as well as Figure 7 As shown, in this embodiment, the first leg 42 includes a first inclined section 421 and a first horizontal section 422, the first inclined section 421 is located between the first horizontal section 422 and the bracket body 41, and the first horizontal section 422 is installed in the first connecting portion 21; the second leg 43 includes a second inclined section 431 and a second horizontal section 432, the second inclined section 431 is located between the second horizontal section 432 and the bracket body 41, and the second horizontal section 432 is installed in the second connecting portion 22. The above arrangement can improve the structural strength of the first leg 42 and the second leg 43, and prevent the first leg 42 and the second leg 43 from being damaged.

[0043] like Figure 1 , Figure 2 as well as Figure 7 As shown, in this embodiment, an inner convex edge 111 is provided on the inner wall of the mounting opening 11, the first connection portion 21 and the second connection portion 22 are both located on the inner convex edge 111, and the bottom cover 30 is covered on the inner convex edge 111. The inner convex edge 111 can effectively support the power board bracket 40 and the bottom cover 30, so that the power board bracket 40 can be clamped between the inner convex edge 111 and the bottom cover 30, thereby fixing the power board bracket 40.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the first connecting portion 21 includes a first concave structure 211, the second connecting portion 22 includes a second concave structure 221, a portion of the structure of the first leg 42 is inserted into the first concave structure 211, and a portion of the structure of the second leg 43 is inserted into the second concave structure 221. The first concave structure 211 can limit the position of the first leg 42, and the second concave structure 221 can limit the position of the second leg 43, thereby making the position of the first leg 42 and the second leg 43 more stable. There is a certain angle between the first concave structure 211 and the second concave structure 221, and the angle matches the angle a, thereby making it impossible to place it in reverse.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the first leg 42 is interference fit with the first upper concave structure 211, and the second leg 43 is interference fit with the second upper concave structure 221. The above arrangement can make the positions of the first leg 42 and the second leg 43 more stable, that is, it can improve the stability of the power board bracket 40.

[0046] Specifically, the above-mentioned interference fit is based on the matching of the angle between the first concave structure 211 and the second concave structure 221 with the angle a, that is, the cross-sectional area of ​​the first leg 42 is larger than the cross-sectional area of ​​the first concave structure 211, and the cross-sectional area of ​​the second leg 43 is larger than the cross-sectional area of ​​the second concave structure 221.

[0047] Of course, the above-mentioned interference fit can also mean that the angle between the first concave structure 211 and the second concave structure 221 can be greater than the angle a or less than the angle a, that is, the difference between the angle between the first concave structure 211 and the second concave structure 221 and the angle a is between 5°, so that when the first leg 42 is installed in the first concave structure 211 and the second leg 43 is installed in the second concave structure 221, the side wall of the first leg 42 can abut against the side wall of the first concave structure 211, and / or the side wall of the second leg 43 can abut against the side wall of the second concave structure 221, which can also improve the stability of the power board bracket 40.

[0048] like Figure 6 and Figure 7 As shown, in this embodiment, the bottom cover 30 abuts against the surface of the first leg 42 facing the bottom cover 30, and the bottom cover 30 abuts against the surface of the second leg 43 facing the bottom cover 30. The bottom cover 30 abuts against the first leg 42 and the second leg 43, that is, the bottom cover 30 can limit the power board bracket 40, so there is no need to use other structures to fix the power board bracket 40, thereby reducing the difficulty of assembly.

[0049] like Figure 4 As shown, in this embodiment, the first leg 42 includes a first plate body 423 and a first reinforcing rib 424 disposed at the edge of the first plate body 423, and the second leg 43 includes a second plate body 433 and a second reinforcing rib 434 disposed at the edge of the second plate body 433. The above arrangement can effectively improve the structural strength of the first leg 42 and the second leg 43, thereby preventing damage during transportation and falling.

[0050] Specifically, first reinforcing ribs 424 are disposed at the edges of the first plate body 423 and the first extension leg 44 , and second reinforcing ribs 434 are disposed at the edges of the second plate body 433 and the second extension leg 45 .

[0051] According to another aspect of the present application, a cooking utensil is provided. The cooking utensil of this embodiment includes a base assembly, and the base assembly is the above-mentioned base assembly. The power board bracket 40 in the above-mentioned base assembly will not be installed upside down, and the power board bracket 40 can be fixed only by the bottom cover 30, that is, the power board bracket 40 does not need to be fixed by other structures, so the cooking utensil with the above-mentioned base assembly also has the above-mentioned advantages.

[0052] The cooking device of this embodiment further comprises a shell and a heat preservation cover, wherein the shell is connected to the base 10, the heat preservation cover is arranged inside the shell, and the base 10 and the heat preservation cover are connected via a Z-shaped frame, so that it is convenient to arrange the holes of different internal parts, and the versatility is high.

[0053] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
