[0031] The embodiment of the utility model discloses a shell structure applied to an electric rice cooker, and the specific structure and functions of the shell structure provided by the embodiment of the utility model will be further explained below in combination with the text and drawings.

[0032] Referring to Figure 1 And Figure 2 According to the shell structure provided by the first aspect of the utility model, the shell structure comprises a support shell 100 and an outer plate 200, the support shell 100 can be made of plastic with good strength and heat resistance, a first positioning rib 110 is arranged on the upper end of the support shell 100 by injection molding or mechanical processing, and the width of the first positioning rib 110 can be set according to actual needs. Meanwhile, a first glue groove 120 is arranged on the outer wall of the support shell 100, the first glue groove 120 is filled with fixing glue (not shown in the drawing), the depth and width of the first glue groove 120 should be determined according to the performance and bonding requirements of the selected fixing glue, and the fixing glue can be fully filled and provide sufficient bonding force. The material of the outer plate 200 can also be plastic or metal material matched with the support shell 100, the shape and size of the outer plate 200 should be matched with the outer wall of the support shell 100, and the outer plate 200 can be closely arranged on the outer wall of the support shell 100. A contact surface matched with the first positioning rib 110 is reserved on the upper end of the outer plate 200, so that the outer plate 200 can be stably contacted on the lower side of the first positioning rib 110. The first glue groove 120 of the support shell 100 is filled with fixing glue. The fixing glue can be selected from adhesives with good bonding performance, high temperature resistance, aging resistance and moderate curing time, such as silicone glue, epoxy resin glue and polyurethane glue. During the filling process, attention should be paid to uniform filling of the glue groove to avoid the accumulation of bubbles or glue liquid, so as to ensure the uniformity and reliability of the bonding effect.

[0033] During installation, the outer plate 200 is arranged on the outer wall of the support shell 100, the upper end of the outer plate 200 is closely contacted with the lower side of the first positioning rib 110, the inner wall of the outer plate 200 is matched with the outer wall of the support shell 100, and the outer plate 200 is ensured to be contacted with the fixing glue filled in the first glue groove 120. In addition, during the assembly process, appropriate tools or fixtures can be used to apply pressure to the outer plate 200, so that the outer plate 200 is closely combined with the support shell 100, the fixing glue is firmly bonded and fixed on the support shell 100 under the pressure and self-curing effect of the fixing glue, and the assembly of the shell structure is completed.

[0034] According to the shell structure provided by the first aspect of the utility model, the first positioning rib 110 extending outward is arranged on the upper end of the supporting shell 100, the first glue groove 120 is arranged around the outer wall, and the fixed glue is filled in the first glue groove 120, then the outer plate 200 is arranged around the outer wall of the supporting shell 100, the upper end of the outer plate 200 abuts the lower side of the first positioning rib 110, and the inner wall of the outer plate 200 abuts the fixed glue and is attached to the outer wall of the supporting shell 100, so that the traditional mode of fixing the outer plate 200 by multiple screws is abandoned. On the one hand, multiple screws do not need to be tightened one by one, the installation operation process is greatly simplified, the time and effort required for installation are significantly saved, the assembly efficiency of the electric rice cooker is effectively improved, the production process of the electric rice cooker is more convenient and efficient. On the other hand, since the use of screws is reduced, the error probability caused by the untightening or damage of the screws is reduced, and the stability of the overall structure of the electric rice cooker is enhanced, thereby providing a strong guarantee for the normal use and long-term stable operation of the electric rice cooker, and improving the reliability and service life of the product.

[0035] It can be understood that, in the assembly process, a certain pressure needs to be applied to the outer plate 200 by using appropriate tools or fixtures to make the outer plate 200 tightly combined with the supporting shell 100 to wait for the solidification of the fixed glue. However, since the solidification time of the fixed glue (such as silicone glue) is relatively long, the shell structure needs to wait for a long time on the tools or fixtures for the solidification of the fixed glue, which easily affects the use efficiency of the tools or fixtures.

[0036] To solve this problem, with reference to Figure 2 and Figure 3 In some embodiments, the outer wall of the supporting shell 100 is arranged with a second glue groove 130, and the second glue groove 130 is arranged in a direction from top to bottom and spaced from the first glue groove 120, and the spacing distance can be determined according to the actual size and structural strength requirement of the shell. The shape and size of the second glue groove 130 are similar to those of the first glue groove 120, and the depth and width are also set according to the characteristics of the selected pre-tightening glue, so as to ensure that the pre-tightening glue can be effectively filled and play a pre-tightening role.

[0037] The second glue groove 130 is filled with pre-tightening glue (not shown in the figure), and the pre-tightening glue is selected from adhesives with rapid solidification to generate pre-tightening force, such as hot melt glue, silicone adhesive, etc. When filling the pre-tightening glue, it is also necessary to ensure uniform filling to avoid bubbles and accumulation, so that the pre-tightening glue forms a uniform glue layer in the second glue groove 130.

[0038] In the assembling process, when the outer plate 200 is arranged outside the outer wall of the supporting shell 100 and abuts against the fixing glue in the first glue groove 120, the inner wall of the outer plate 200 also abuts against the pre-tightening glue in the second glue groove 130. Due to the rapid solidification characteristics of the pre-tightening glue, the outer plate 200 can be quickly fixed on the outer wall of the supporting shell 100, thereby avoiding the phenomenon that the shell structure needs to wait for the solidification of the fixing glue on the tool or the tooling, and being beneficial to improve the use efficiency of the tool or the tooling and improve the production efficiency.

[0039] It can be understood that the fixing glue and the pre-tightening glue simultaneously bond the outer plate 200, which can better fix the outer plate 200 on the outer wall of the supporting shell 100, and is beneficial to ensure the stability of the fixing.

[0040] With reference to Figures 1 to 3 According to the shell structure provided by the first aspect of the present application, the outer plate 200 has opposite first and second ends 210 and 220, and a tensioning member 300 is connected between the first and second ends 210 and 220. The tensioning member 300 can be made of a material such as a metal wire, a metal strip, a plastic strip or a rubber strip, which has a certain elasticity and strength. The length and size of the tensioning member 300 are determined according to the actual size of the outer plate 200. Generally, the length is slightly smaller than the straight-line distance between the first and second ends 210 and 220 of the outer plate 200, so as to generate a proper tensioning force when connected.

[0041] It can be understood that the tensioning member 300 can be fixed on the outer plate 200 by screwing, bonding or buckle connection and the like. After the connection of the tensioning member 300 is completed, due to its own elastic properties, it will exert an inward tensioning force on the outer plate 200, so that the outer plate 200 maintains a certain pre-tightening state in the circumferential direction, and the outer plate 200 can be stably attached to the outer wall of the supporting shell 100, thereby enhancing the structural stability and integrity of the outer plate 200, effectively avoiding the problems such as loosening and deformation of the outer plate 200 that may occur during the bonding process, and further improving the reliability and service life of the electric rice cooker shell structure.

[0042] With reference to Figure 2According to the shell structure provided by the first aspect of the utility model, the tensioning piece 300 is a spring, the spring has good elastic performance and stable tension force output, and can effectively meet the tensioning requirement of the outer plate 200. In order to facilitate the connection between the spring and the outer plate 200, hooks are arranged at the two ends of the spring. The first end 210 and the second end 220 of the outer plate 200 are respectively provided with a hanging hole. The shape of the hanging hole can be circular, oval or other shapes suitable for the hanging of the hook, and the diameter or size thereof should be slightly larger than the diameter of the hook, so that the hook can be smoothly inserted and hung in the hanging hole. During assembly, the hooks at the two ends of the spring are respectively aligned with the hanging holes of the first end 210 and the second end 220 of the outer plate 200, and then the hooks are inserted into the hanging holes, so that the two ends of the spring are firmly hung on the outer plate 200. The spring has a certain elastic potential in a natural state, and when it is connected at the two ends of the outer plate 200, it will automatically apply an inward tension force to the outer plate 200, so that the outer plate 200 remains in a tightly tensioned state.

[0043] With reference to Figure 2 According to the shell structure provided by the first aspect of the utility model, in order to make the outer plate 200 be stressed more evenly in the circumferential direction and improve the overall stability, a plurality of tensioning pieces 300 are connected between the first end 210 and the second end 220 of the outer plate 200. The plurality of tensioning pieces 300 are arranged in a downward direction, and the interval distance thereof can be determined according to the size of the outer plate 200 and the required tension force distribution, so as to ensure that the outer plate 200 can be effectively tensioned at different height positions. The plurality of tensioning pieces 300 can adopt the same structure form, such as springs, and the hooks are arranged at the two ends of the springs, and the first end 210 and the second end 220 of the outer plate 200 are correspondingly provided with a plurality of hanging holes, and the hooks at the two ends of the spring are respectively hung in the corresponding hanging holes. Different forms of tensioning pieces 300 can also be combined as required, for example, some are springs, and some are plastic belts or rubber belts with certain elasticity, so as to meet different tensioning requirements and structural strength requirements.

[0044] In the actual assembly process, the plurality of tensioning pieces 300 are arranged between the first end 210 and the second end 220 of the outer plate 200 according to the predetermined position and interval, so as to ensure that each tensioning piece 300 can be correctly connected and tensioned. The plurality of tensioning pieces 300 are arranged at intervals, so that the outer plate 200 is subjected to uniform tension in all directions, effectively preventing the outer plate 200 from being deformed or loosened in the use process.

[0045] With reference to Figure 2 and Figure 3According to the shell structure provided by the first aspect of the utility model, the lower end of the supporting shell 100 is formed with the second positioning rib 140 extending outward in the circumferential direction by injection molding or mechanical processing. The shape and size of the second positioning rib 140 are designed to be matched with the lower end of the outer plate 200, so that the stable positioning effect can be achieved, and meanwhile, the overall assembly and appearance are not affected. The lower end of the outer plate 200 is correspondingly provided with the abutting surface matched with the second positioning rib 140. During assembly, the outer plate 200 is arranged around the outer wall of the supporting shell 100, so that the upper end of the outer plate 200 abuts against the lower side of the first positioning rib 110, and meanwhile, the lower end of the outer plate 200 abuts against the upper side of the second positioning rib 140. Through the cooperation between the positioning ribs at the upper end and the lower end and the outer plate 200, the double positioning of the outer plate 200 in the vertical direction is formed, the displacement of the outer plate 200 in the up-down direction is effectively limited, and the stability and reliability of the connection between the outer plate 200 and the supporting shell 100 are enhanced.

[0046] With reference to Figure 3 According to the shell structure provided by the first aspect of the utility model, the outer wall of the supporting shell 100 is processed with the key hole 150 corresponding to the position of the electric rice cooker key. In order to improve the positioning precision and stability of the outer plate 200 installed on the supporting shell 100, the third positioning rib 160 is arranged around the outer edge of the key hole 150. The shape and size of the third positioning rib 160 are designed to be matched with the positioning hole 230 on the outer plate 200, so that the accurate positioning effect can be achieved, and meanwhile, the normal operation of the key is not affected. The outer plate 200 is correspondingly provided with the positioning hole 230, and the shape and size of the positioning hole 230 should be matched with the third positioning rib 160, so that the third positioning rib 160 can be smoothly arranged in the positioning hole 230. During assembly, when the outer plate 200 is arranged around the outer wall of the supporting shell 100, the positioning hole 230 on the outer plate 200 is aligned with the third positioning rib 160 on the supporting shell 100, then the outer plate 200 is pressed downward, so that the third positioning rib 160 is arranged in the positioning hole 230, thereby realizing the accurate connection and positioning of the outer plate 200 and the supporting shell 100 in the key area.

[0047] With reference to Figure 2 and Figure 3 According to the shell structure provided by the first aspect of the utility model, in order to make the connection between the outer plate 200 and the supporting shell 100 more firm and reliable, a plurality of first glue grooves 120 are arranged on the outer wall of the supporting shell 100 in the direction from top to bottom. The interval distance between the plurality of first glue grooves 120 can be set according to the height of the supporting shell 100 and the required bonding strength. In each first glue groove 120, the fixing glue is filled. When the fixing glue is filled, it is necessary to ensure that the fixing glue is uniformly filled in each first glue groove 120, so as to avoid the situation that air bubbles or glue liquid are unevenly accumulated, so as to ensure that the fixing glue in each first glue groove 120 can fully play the bonding role.

[0048] In the assembling process, when the outer plate 200 is arranged around the outer wall of the supporting shell 100, the inner wall of the outer plate 200 is attached to the plurality of first glue grooves 120 on the outer wall of the supporting shell 100 and abuts against the fixing glue in the first glue grooves 120. Since the plurality of first glue grooves 120 are filled with the fixing glue, the bonding area between the outer plate 200 and the supporting shell 100 is increased, and the bonding strength is significantly improved, thereby effectively enhancing the stability and reliability of the connection between the outer plate 200 and the supporting shell 100.

[0049] With reference to Figure 2 and Figure 3 According to the shell structure provided in the first aspect of the present application, in order to enhance the pre-tightening force between the supporting shell 100 and the outer plate 200 and the overall sealing performance, a plurality of second glue grooves 130 are arranged on the outer wall of the supporting shell 100 in the direction from top to bottom. The interval distance between the plurality of second glue grooves 130 can be set according to the height of the supporting shell 100 and the required pre-tightening effect. In each second glue groove 130, pre-tightening glue is filled. In the assembling process, when the outer plate 200 is arranged around the outer wall of the supporting shell 100, the inner wall of the outer plate 200 is sequentially attached to the plurality of second glue grooves 130 on the outer wall of the supporting shell 100 and abuts against the pre-tightening glue in each second glue groove 130. Since the plurality of second glue grooves 130 are filled with the pre-tightening glue, the pre-tightening force between the outer plate 200 and the supporting shell 100 is enhanced, and at the same time, the elastic properties of the pre-tightening glue also enable the shell to maintain good sealing performance in all directions, effectively preventing dust, water vapor and the like from entering the inside of the shell.

[0050] The electric rice cooker provided in the second aspect of the present application has all the beneficial effects of the first aspect of the present application.
