Description

Technical Field

[0001] This utility model relates to the technical field of electric cookers, and in particular to a heat insulation structure on the cooker body. Background Technology

[0002] Traditional heat insulation columns only serve to insulate heat and withstand upward tension. When the inner pot is under load and experiences downward force, this force needs to be transmitted through the outer shell and then to the bottom cover. This necessitates a relatively thick outer shell to withstand the pressure from the inner pot. For example, patent document CN209768734U also discloses an electric fryer, whose heat insulation device suffers from similar problems. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a heat insulation structure for use on a pot body that can withstand the pressure of the inner pot.

The bottom of the bottom cover has a countersunk hole, and a heat insulation column that can be inserted into the pot body through the countersunk hole is disposed in the countersunk hole. The heat insulation column includes a column body and a pusher head disposed on the end of the column body and abutting against the upper wall of the countersunk hole. The inner side wall of the countersunk hole is provided with a plurality of raised ribs that abut against the lower surface of the pusher head. There is a gap between the upper surface of the raised ribs and the upper wall of the countersunk hole. The pusher head is provided with a guide groove for passing through the raised ribs.

[0008] In a preferred embodiment of this utility model, there is a gap between the heat insulation column and the sidewall of the countersunk hole, and the gap is 0-1mm.

[0009] In a preferred embodiment of this utility model, the lower surface of the abutment head is provided with a plurality of limiting protrusions that can abut against the side of the rib.

[0010] In a preferred embodiment of this utility model, the guide groove divides the abutment head into several abutment tops that can abut against the lower surface of the abutment head, and the limiting protrusion is disposed on the abutment tops.

[0011] In a preferred embodiment of this utility model, the lower side of the top abutment is provided with a chamfer.

[0012] In a preferred embodiment of this utility model, the lower surface of the abutment head is provided with a groove in the shape of a line or a cross.

[0013] In a preferred embodiment of this utility model, the bottom of the pot is provided with a downwardly extending connecting post, the heat insulation post is hollow to form a through hole, and the heat insulation post is fixed to the connecting post by means of a threaded connection.

[0014] The beneficial effects of this utility model are: by using the protruding ribs on the inner wall of the bottom shell countersunk hole that can abut against the heat insulation column, the heat insulation column can not only withstand upward tension but also downward pressure, thus transforming the outer shell from a load-bearing component into a decorative component. This makes the outer shell lighter and more beautiful, thereby reducing production costs. Attached Figure Description

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0017] Reference Figures 1 to 6A heat insulation structure for a pot includes a pot body 1, an outer shell 2 disposed on the outside of the pot body 1, and a bottom cover 3 disposed at the bottom of the outer shell 2. The bottom cover 3 has a countersunk hole 31 at its bottom, and a heat insulation column 4, which can be inserted into the pot body through the countersunk hole 31, is provided within the countersunk hole 31. The heat insulation column 4 includes a column body 41 and abutting head 42 disposed at the end of the column body 41 and abutting against the upper wall of the countersunk hole 31. The inner wall of the countersunk hole 31 has several raised ribs 32 that abut against the lower surface of the abutting head 42. There is a gap between the upper surface of the raised ribs 32 and the upper wall of the countersunk hole 31. The abutting head 42 has a guide groove 421 for passing through the raised ribs 32. This design allows the heat insulation column 4 to withstand both upward tension and downward pressure, transforming the outer shell 2 from a load-bearing component into a decorative element. This makes the outer shell 2 lighter and more aesthetically pleasing, thereby reducing production costs.

[0018] In this design, the number of the protruding ribs 32 is at least two, and they are evenly distributed on the inner wall of the countersunk hole 31. This ensures that the protruding ribs 32 can provide balanced support for the heat insulation column 4, thereby improving the reliability and durability of its structure.

[0019] In this design, the lower end of the rib 32 is V-shaped, which facilitates smoother installation and makes it easier for the heat insulation column 4 to be inserted into the countersunk hole 31. Specifically, the cross-sectional area of ​​the rib 32 gradually increases from bottom to top, and the upper surface of the rib 32 is a horizontal plane.

[0020] In this design, there is a gap between the heat insulation column 4 and the sidewall of the countersunk hole 31, the gap being 0-1mm, in order to avoid structural stress caused by thermal expansion and contraction, so that the heat insulation column 4 can maintain good stability.

[0021] In this design, the lower surface of the abutment head 42 is provided with several limiting protrusions 422 that abut against the sides of the rib 32, facilitating positioning of the heat insulation column 4 during installation. When the heat insulation column 4 is inserted into the countersunk hole 31, it is screwed until the limiting protrusions 422 abut against the rib 32 to complete the assembly. Specifically, the guide groove 421 divides the abutment head 42 into several abutment tops 423 that abut against the lower surface of the abutment head 42, and the limiting protrusions 422 are located on the abutment tops 423. Furthermore, to facilitate the screwing installation of the heat insulation column 4, the lower sides of each abutment top 423 are chamfered.

[0022] In this design, the lower surface of the abutment head 42 is provided with a slotted or cross-shaped groove 424, which can be used to operate with a screwdriver or other tools to facilitate the installation or removal of the heat insulation column 4.

[0023] In this design, the bottom of the inner pot 1 is provided with a downwardly extending connecting post 11, and the heat insulation post 4 is hollow inside to form a through hole 43. The heat insulation post 4 is fixed to the connecting post 11 by a threaded connection, thereby connecting the inner pot 1 to the bottom shell through the heat insulation post 4.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
