Description

Technical Field

[0001] The utility model relates to the technical field of rice cookers, and particularly relates to a fixing structure and a rice cooker. Background Art

[0002] With the increasing maturity of IH heating technology, IH heating rice cookers have gradually become popular. However, IH heating technology also leads to an increase in radiation generated during heating. To solve this problem, some products add an aluminum radiation shielding plate to the base of the rice cooker.

[0003] However, the aluminum radiation shielding plate has weak elasticity and cannot rebound after deformation. During ordinary interference fit assembly, it is extremely easy to cause the deformation of the radiation shielding plate, resulting in insufficient interference amount, and ultimately leading to insecure fixation of the aluminum interference fit structure-assembled radiation shielding plate. When the rice cooker is operating, the radiation shielding plate resonates due to the operation of the exhaust fan motor, generating noise and affecting the user experience.

[0004] Therefore, the prior art needs to be further developed. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies and provide a fixing structure and a rice cooker to solve the technical problem that the radiation shielding plate generates noise due to insecure fixation in the related art.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions: A fixing structure is provided, including: a bottom plate; a connecting component, which protrudes from the surface of the bottom plate and is detachably connected to the component to be fixed; a supporting component, which protrudes from the surface of the bottom plate and is spaced apart from the connecting component, and the supporting component abuts against the component to be fixed to push the component to be fixed to abut against the connecting component.

[0007] Further, the connecting component includes: a connecting plate body, which is connected to the bottom plate; a limiting protrusion, which is arranged on the connecting plate body and is used for being clamped with a clamping groove on the component to be fixed; a first limiting surface is arranged on one side of the limiting protrusion close to the bottom plate, and the first limiting surface abuts against the component to be fixed.

[0008] Further, the shortest distance between the first limiting surface and the bottom plate gradually increases in the direction away from the connecting plate body.

[0009] Further, the connecting component includes a limiting plate body, which is connected to the connecting plate body and is spaced apart from the limiting protrusion. The limiting plate body is arranged on one side of the limiting protrusion close to the bottom plate, and the limiting plate body has a second limiting surface, and the second limiting surface abuts against the component to be fixed.

[0010] Further, there are multiple connecting components, which are arranged at intervals and evenly distributed in the circumferential direction.

[0011] Further, there are multiple supporting components, which are distributed around a preset axis; the shortest distances between the multiple supporting components and the preset axis are all smaller than the shortest distances between the multiple connecting components and the preset axis.

[0012] Further, the supporting component is telescopically connected to the bottom plate.

[0013] Further, the height of the supporting component in the vertical direction is greater than the height of the connecting component in the vertical direction.

[0014] Further, positioning holes are provided on the bottom plate, and limiting blocks are arranged inside the positioning holes. The limiting blocks are in contact with the component to be fixed to limit the movement of the component to be fixed.

[0015] An electric rice cooker includes: a fixing structure; a component to be fixed, which is connected to the bottom plate; and a housing, where the fixing structure is arranged inside the housing.

[0016] Beneficial effects:

[0017] The fixing structure of the present application causes the center of the radiation shielding plate to be lifted by the support column and the edge to be pulled downward by the buckle, and limits the radiation shielding plate from two opposite directions, effectively constraining it, and solving the problem that the radiation shielding plate is loosely assembled, resulting in resonance and noise of the radiation shielding plate after the exhaust fan motor operates.

[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] According to an embodiment of the present utility model, a fixing structure is provided for fixing a component to be fixed. Please refer to Figures 1 to 6 , including: a bottom plate 1; a connecting component 2, the connecting component 2 protrudes from the surface of the bottom plate 1, and the connecting component 2 is detachably connected to the component to be fixed; a support component 3, the support component 3 protrudes from the surface of the bottom plate 1, the support component 3 is arranged at an interval from the connecting component 2, and the support component 3 abuts against the component to be fixed to push the component to be fixed to abut against the connecting component 2.

[0030] With the above arrangement, the support component 3 jacks up the component to be fixed, and the connecting component 2 pulls down the component to be fixed. The two cooperate from opposite directions to limit the component to be fixed, making the connection between the component to be fixed and the bottom plate 1 more firm, and solving the technical problem that the component to be fixed generates noise due to insufficient fixation in the related art.

[0031] Specifically, the component to be fixed is the radiation protection plate of a rice cooker.

[0032] Preferably, the component to be fixed has an annular structure, is made of aluminum, and has a very thin thickness.

[0033] In the fixing structure of this embodiment, refer to Figures 2 to 3, the connecting member 2 includes: a connecting plate body 21, the connecting plate body 21 is connected to the bottom plate 1; a limiting protrusion 22, the limiting protrusion 22 is arranged on the connecting plate body 21, and the limiting protrusion 22 is used for being clamped with a clamping groove on the component to be fixed; a first limiting surface 221 is arranged on one side of the limiting protrusion 22 close to the bottom plate 1, and the first limiting surface 221 abuts against the component to be fixed. In this way, the limiting protrusion 22 is connected to the bottom plate 1 through the connecting plate body 21, the limiting protrusion 22 is clamped with the clamping groove on the component to be fixed, and when the component to be fixed is connected to the bottom plate 1, the movement of the component to be fixed in the vertical direction is restricted by the limiting protrusion 22.

[0034] In the fixing structure of this embodiment, refer to Figure 3 , the shortest distance between the first limiting surface 221 and the bottom plate 1 gradually increases in the direction away from the connecting plate body 21. In this way, when the component to be fixed is installed or disassembled, the clamping groove on the component to be fixed slides along the inclined first limiting surface 221, making the relative movement between the clamping groove and the limiting protrusion 22 smoother, reducing the deformation of the connecting plate body 21 during the disassembly process, and prolonging the service life of the fixing structure.

[0035] In the fixing structure of this embodiment, refer to Figure 3 , the connecting member 2 includes a limiting plate body 23, the limiting plate body 23 is connected to the connecting plate body 21, the limiting plate body 23 is arranged at an interval from the limiting protrusion 22, the limiting plate body 23 is arranged on the side of the limiting protrusion 22 close to the bottom plate 1, and the limiting plate body 23 has a second limiting surface 231, and the second limiting surface 231 abuts against the component to be fixed. In this way, after the limiting protrusion 22 is clamped with the clamping groove on the component to be fixed, the component to be fixed is restricted by the limiting plate body 23 so that it cannot continue to move downward, reducing the space for relative movement between the fixing structure and the component to be fixed, making the connection of the fixing structure more stable, and avoiding noise generated by the component to be fixed due to insecure fixation.

[0036] Specifically, there are "shoulders" (i.e., the limiting plate body 23) on both sides of the connecting plate body 21, which can support the radiation protection plate (the component to be fixed), preventing the edge position of the component to be fixed from collapsing severely after the supporting member 3 jacks up the component to be fixed.

[0037] In the fixing structure of this embodiment, refer to Figure 1 、 Figure 6 , there are multiple connecting members 2, the multiple connecting members 2 are arranged at intervals, and the multiple connecting members 2 are evenly distributed along the circumferential direction. In this way, the multiple connecting members 2 cooperate with the component to be fixed, and can limit the movement of the component to be fixed from multiple directions, making the fixation of the component to be fixed more firm, and avoiding noise generated by the component to be fixed due to insecure fixation.

[0038] Preferably, the connecting members 2 are distributed at intervals of 120° with the center of the annular circle of the radiation shielding plate as the center, the straight line passing through the center and perpendicular to the bottom plate 1 as the axis, and the dimension B as the radius, with a total of 3. The triangular structure is the most stable, and 3 connecting members 2 can meet the purpose of pulling the radiation shielding plate (the component to be fixed). Moreover, the more the number, the more operation processes, which is not conducive to lean design.

[0039] In the fixing structure of this embodiment, referring to Figure 1 、 Figure 6 , there are multiple supporting members 3, and the multiple supporting members 3 are distributed around the preset axis; the shortest distances between the multiple supporting members 3 and the preset axis are all smaller than the shortest distances between the multiple connecting members 2 and the preset axis. In this way, the supporting members 3 abut against the part of the component to be fixed close to the center, jack up the part at the center of the component to be fixed, the connecting members 2 are clamped with the part at the edge of the component to be fixed, and pull down the component to be fixed. The supporting members 3 and the connecting members 2 cooperate with each other to fix the component to be fixed more firmly on the bottom plate 1, avoiding noise caused by loose fixing of the component to be fixed.

[0040] Specifically, the distance A of the supporting member 3 from the center of the circle should be smaller than the distance B of the connecting member 2 from the center of the circle, so as to ensure that the inner part is higher and the outer part is lower after installing the radiation shielding plate (the component to be fixed), reducing the assembly difficulty. At the same time, it is ensured that the supporting member 3 at the near point supports and jacks up, and the connecting member 2 at the far point clamps and pulls, so that the radiation shielding plate is firmly fixed.

[0041] Preferably, referring to Figure 6 , the supporting members 3 are distributed at intervals of 120° with the center of the annular circle of the radiation shielding plate as the center, the straight line passing through the center and perpendicular to the bottom plate 1 as the axis, and the dimension A as the radius, with a total of 3. Since the triangular support structure is the most stable, three supporting members 3 can meet the purpose of supporting the radiation shielding plate (the component to be fixed); the more the number of the supporting members 3, the more operation processes, which is not conducive to lean design.

[0042] Preferably, the connecting members 2 and the supporting members 3 are arranged at equal intervals, which is conducive to the installation of the radiation shielding plate (the component to be fixed).

[0043] In the fixing structure of this embodiment, referring to Figures 7 to 8 , the supporting members 3 are connected to the bottom plate 1, and the supporting members 3 are telescopically arranged on the bottom plate 1. In this way, when installing the component to be fixed, the supporting members 3 can contract downward after being squeezed by the component to be fixed. When the component to be fixed abuts against the connecting members 2, the supporting members 3 rebound to apply an upward force to the component to be fixed, jacking up the middle part of the component to be fixed.

[0044] Embodiment 1:

[0045] Referring to Figure 7, the support member 3 and the bottom plate 1 are connected by a spring, and there is a guide sleeve on the bottom plate 1 that guides the support member 3. In this way, while the support member 3 can be telescoped, it will not tip over, and the support for the component to be fixed is more stable.

[0046] Embodiment 2:

[0047] Refer to Figure 8 , on the side of the bottom plate 1 away from the support member 3, a connecting plate is further provided. The connecting plate is connected to the support member 3 by a spring. There is a through hole on the bottom plate 1 for the support member 3 to pass through. At the same time, the through hole on the bottom plate 1 guides the support member 3, so that while the support member 3 can be telescoped, it will not tip over, and the support for the component to be fixed is more stable.

[0048] In the fixing structure of this embodiment, refer to Figure 3 , the height of the support member 3 in the vertical direction is greater than the height of the connecting member 2 in the vertical direction. In this way, after the edge of the component to be fixed abuts against the connecting member 2, the inside of the component to be fixed abuts against the support member 3. Since the height of the support member 3 is higher than that of the connecting member 2, the component to be fixed is in a state where it is slightly higher in the middle and slightly lower on the outside, so that the component to be fixed receives reaction forces in two directions, making the connection between the component to be fixed and the bottom plate 1 more firm, and avoiding noise caused by the component to be fixed not being firmly fixed.

[0049] Specifically, the height of the support member 3 is slightly higher than that of the connecting member 2, which can ensure that after installing the radiation protection plate (the component to be fixed), the support member 3 contacts the radiation protection plate and has a jacking effect. The height difference cannot be too large, otherwise the radiation protection plate will be deformed greatly after installation, affecting the use experience.

[0050] In the fixing structure of this embodiment, refer to Figure 1 , there is a positioning hole 11 on the bottom plate 1, and a limiting block 12 is arranged inside the positioning hole 11. The limiting block 12 abuts against the component to be fixed to limit the movement of the component to be fixed. In this way, there is a round hole in the center of the component to be fixed that cooperates with the limiting block 12. After the limiting block 12 and the round hole are clamped, the displacement of the component to be fixed in the horizontal direction can be restricted, avoiding the movement of the component to be fixed. At the same time, aligning the positioning hole 11 and the round hole in the center of the component to be fixed can position the component to be fixed.

[0051] This embodiment provides a rice cooker, refer to Figure 6 , the rice cooker includes: a fixing structure; a component to be fixed, which is connected to the bottom plate 1; and a housing 5, and the fixing structure is arranged inside the housing 5.

[0052] With the above settings, the component to be fixed is fixed in the housing 5 through a fixed structure and stably connected to the bottom plate 1, so that the component to be fixed is effectively constrained, solving the problem that the assembly of the component to be fixed is loose, resulting in noise generated by resonance after the exhaust fan motor runs.

[0053] Embodiment 3:

[0054] When installing the radiation protection plate (the component to be fixed), first snap one hole of the radiation protection plate with the connecting component 2 and pull it tightly in the radially opposite directions, and then snap the other two holes with the connecting component 2 respectively. The limiting protrusion 22 has a pulling effect on the radiation protection plate, and the limiting plate body 23 supports the radiation protection plate to prevent serious sagging at the edge position. At the same time, the supporting component 3 closer to the center of the circle slightly higher than the first limiting surface 221 of the connecting component 2 has an internal supporting effect on the radiation protection plate. Through the downward pull of the limiting protrusion 22, the support of the limiting plate body 23 and the upward support of the supporting component 3, the radiation protection plate is effectively constrained and the overall deformation is very small. Solved the problem that the assembly of the radiation protection plate is loose, resulting in noise generated by resonance of the radiation protection plate after the exhaust fan motor runs.
