Description

Technical Field

[0001] This application relates to the field of stove or cooker technology, specifically to a stove appliance. Background Technology

[0002] In the commercial kitchen equipment sector, commercial stoves, as commonly used heating devices, have structural designs that directly impact their stability and lifespan. Currently, the overall structure of commercial stoves typically consists of two main parts: a base shell and an outer shell. These two parts are usually connected using screws to ensure a secure assembly. Simultaneously, to ensure stable installation in the kitchen environment, the metal outer shell is mounted under the countertop using an additional, designed fixing structure. This transfers the weight of the stove and the forces generated during operation to the supporting structure.

[0003] From a material selection perspective, the bottom shell, as the load-bearing foundation for the internal components of the stove, often requires irregular shaping to accommodate the installation needs of different parts. For ease of processing and cost control, the bottom shell is typically made of plastic, due to its good plasticity, which allows it to meet the processing requirements of complex shapes. The heating element, as the core functional component of the stove, is generally located in the cavity between the bottom shell and the outer shell, generating heat through the conversion of electrical or gas energy to heat the food. However, in actual use, the above structural design has obvious technical defects. Because the heating element generates a large amount of heat during operation, this heat not only acts on the heating area but is also conducted through the metal casing. Some of this heat is transferred to the bottom shell via screws, making it difficult for the heat to dissipate at the connection between the plastic bottom shell and the outer shell, easily leading to softening due to localized high temperatures. More importantly, the bottom shell bears the weight of various components such as the control module and circuit assemblies. This weight is concentrated at the connection point with the outer shell. When the plastic at the connection softens due to heat, its structural strength decreases significantly, making it unable to withstand the load. This causes the connection between the bottom shell edge and the screws to loosen or even detach. This failure not only affects the normal use of the stove but may also cause short circuits, abnormal heating, and other safety hazards due to detached components, reducing the reliability and safety of commercial stoves. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes: A stove, comprising: The bottom shell is made of plastic and has several lower connection holes. The metal casing has several upper connecting holes, and the metal casing is mounted on the upper end of the bottom shell, with the upper connecting holes corresponding one-to-one with the lower connecting holes. A metal gasket having at least one through hole is disposed on the upper end of the bottom shell and sandwiched between the metal outer shell and the bottom shell, or supported on the lower end face of the bottom shell, wherein the through hole on the metal gasket is aligned with the lower connecting hole; A connecting assembly includes a first connector or a first connector and a second connector, wherein the first connector is used to pass through the upper connecting hole, the through hole and the lower connecting hole to connect the bottom shell, the metal gasket and the metal outer shell; and the second connector is used to pass through the upper connecting hole and the lower connecting hole to connect the bottom shell and the metal outer shell.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: when the metal gasket is clamped between the metal outer shell and the bottom shell, the metal gasket is annular and the metal gasket is provided with two or more through holes.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: when the metal pad is supported at the bottom of the bottom shell, the metal pad has one, two or more, and each metal pad has one or more through holes.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the metal gasket is in the form of a ring, a straight strip, a semi-circular piece, a crescent-shaped piece, an arc-shaped piece, or a straight strip.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the upper or lower end surface of the bottom shell is provided with a receiving groove that matches the metal gasket.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the connecting component is conductive, a hollow column is provided on the upper end surface of the bottom shell, the hollow column penetrates the bottom shell, a conductive connector is installed inside the hollow column, and the conductive connector is in contact with the metal gasket.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the first connecting member and the second connecting member are screws.

[0011] The beneficial effects of this utility model are: When the metal gasket is placed between the bottom shell and the outer metal shell, it acts as an intermediate medium, reducing the direct heat exchange area between the plastic bottom shell and the high-temperature outer shell. This reduces the transfer of heat from the outer metal shell to the connection between the bottom shell and the outer metal shell, preventing localized overheating at the connection point and subsequent softening and connection failure. Furthermore, the metal gasket possesses uniform rigidity and strength, distributing the tightening force of each screw across the entire contact surface of the gasket, which then evenly transmits the force to the bottom shell and the outer shell. This dispersion effect results in more uniform stress distribution at the bottom shell connection, significantly reducing the load per unit area. Even if the bottom shell softens slightly, the rigidity of the metal gasket maintains the stability of the overall connection structure, preventing connection failure due to excessive localized stress. This effectively solves the problem of bottom shell detachment caused by loosening of the connection between the edges and screws after softening at high temperatures. When the metal gasket is placed at the bottom of the bottom shell and connected to the bottom shell through the connecting assembly, when the bottom shell gradually loosens or even completely detaches due to the softening of the plastic, the bottom shell will shift downwards due to gravity. However, the metal gasket at the bottom of the bottom shell forms a physical barrier, preventing the bottom shell from falling further downwards and avoiding complete separation from the outer shell. This solves the problem of the bottom shell falling off due to the loosening of the connection between the edge and the screw after the bottom shell softens at high temperature.
