Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to an oven with a temperature sensor that can be quickly disassembled and installed. Background Technology

[0002] In heat processing equipment such as electric ovens, temperature sensors are typically installed to precisely control the temperature of the inner cavity. The sensor probe extends into the inner cavity to detect the temperature, while its main body is fixed to the outer wall of the inner cavity via a bracket. For wiring and temperature field uniformity considerations, the sensor is usually installed on the rear wall of the inner cavity.

[0003] Currently, the common installation method uses a mechanical fastening structure with bolts and nuts. Since the inner liner is usually made of thin metal sheet with a relatively thin wall, it is generally difficult to directly machine internal threads with sufficient strength. Therefore, a method of fixing by clamping bolts and nuts from both sides is typically used. Specifically, during installation, the bolts are passed through the through holes in the sensor bracket and the inner liner wall from the outside, and then the nuts are screwed on from the outside and tightened to secure the sensor.

[0004] There are areas for improvement in the actual installation and maintenance of this structure: it usually requires two people to work together, one person holding the sensor and aligning it, and the other person using tools to tighten the nuts on the outside. It is inconvenient for a single person to complete the installation or disassembly independently.

[0005] Therefore, the industry needs a temperature sensor mounting structure that is easier for a single person to operate. Summary of the Invention

[0006] The purpose of this invention is to provide a temperature sensor mounting structure and an oven with the same structure, so as to improve the problem of the existing installation method requiring multiple people to cooperate and being inconvenient to operate.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An oven with a quickly detachable temperature sensor includes a body, an inner liner mounted on the body, and a temperature sensing assembly. The temperature sensing assembly includes a temperature sensor and a mounting bracket. One side of the mounting bracket has a sensor mounting hole for mounting the temperature sensor, and the other side has a balancing protrusion. The side wall of the inner liner has a corresponding sensing hole and a balancing hole. The sensing hole is opposite to the sensor mounting hole, and the balancing hole is opposite to the balancing protrusion. An elastic positioning portion is formed on the outer side wall of the inner liner between the sensing hole and the balancing hole. The mounting bracket is detachably fixed to the outer side wall of the inner liner through the elastic positioning portion. The temperature sensor is mounted in the sensor mounting hole and extends into the inner cavity of the inner liner through the sensing hole. The balancing protrusion cooperates with the balancing hole.

[0008] This invention utilizes the slight elastic deformation of the thin inner wall of the mounting bracket by first inserting the probe and then rotating the bracket. During rotation, the main body of the bracket engages with the elastic positioning part for vertical locking, while the balancing protrusion on the other side engages with the balancing hole under pressure for lateral restraint. This allows for a reliable and stable tool-free installation of the temperature sensor in one step. Compared to existing technologies, this invention eliminates the need for bolts, nuts, and other additional fasteners, eliminating the cumbersome installation method that requires two people working together and using tools. It enables rapid assembly and disassembly by a single person using simple rotation, improving installation and maintenance efficiency.

[0009] Furthermore, the elastic positioning part is an elastic cantilever piece, which is formed by partially punching and stretching the inner liner sidewall, so that the elastic cantilever piece has a fixed end connected to the sidewall and a free end that can be elastically deformed. In this design, the cantilever piece has a fixed end connected to the sidewall and a free end that can be elastically deformed; when the mounting bracket rotates and compresses the free end, the cantilever piece undergoes bending deformation, and after the bracket rotates to its position, it rebounds due to the elastic restoring force of the material itself, thereby locking the mounting bracket in place.

[0010] Furthermore, the fixed end of the elastic cantilever plate is its lower end, which is connected to the inner liner sidewall; its free end is the upper end, and the mounting bracket is inserted through the opening between the upper end and the inner liner sidewall during rotational installation. In this design, after the mounting bracket is rotated into position, its lower edge or locking portion is supported or limited by the lower fixed end of the cantilever plate. Since the fixed end is rigidly connected to the inner liner sidewall and cannot move upward, a rigid downward stop is formed, effectively preventing the mounting bracket from falling out downward under gravity or vibration.

[0011] Furthermore, the mounting bracket is plate-shaped, with a slot on its lower center corresponding to the elastic cantilever plate. The slot engages with the connection between the fixed end of the elastic cantilever plate and the inner liner sidewall. In this design, the two side walls of the slot form a double-sided clamping effect on the root of the fixed end of the cantilever plate after engagement. This structure effectively restricts any slight movement or rotation of the mounting bracket in the horizontal plane. Simultaneously, this clamping action, combined with the fixed connection at the lower end of the cantilever plate, constitutes a stable anti-detachment structure, thereby significantly improving the mechanical stability of the connection while enabling quick assembly and disassembly.

[0012] Furthermore, the cross-section of the balancing protrusion is a low-curvature arc surface. The shape of this design provides a smooth guiding effect during installation, making it easy for the protrusion to slide into the balancing hole; at the same time, during disassembly, its gentle arc surface structure also facilitates smooth removal from the hole, thereby achieving auxiliary positioning and anti-rotation functions while supporting rapid assembly and disassembly of the overall structure.

[0013] Furthermore, the balancing protrusion is a protrusion integrally stamped with the mounting bracket. This solution uses a stamping process to create a single integral structure between the balancing protrusion and the mounting bracket, eliminating the parts and processes required for separate assembly.

[0014] Furthermore, the mounting bracket has a connecting lug on its side, which is perpendicular to the main body of the mounting bracket and forms an L-shaped structure. This connecting lug is designed for gripping during installation and removal. In particular, when removal is required, pinching the lug and applying pull force can pull the sensing protrusion out of the sensing hole.

[0015] Furthermore, the cross-section of the elastic cantilever plate is a continuously bent curve, including a first bend and a second bend. The first bend is located at the lower part of the elastic cantilever plate, and its bending direction is outward from the side wall of the inner liner. The second bend is located at the upper part of the elastic cantilever plate, and its bending direction is inward from the outside towards the side wall of the inner liner, with the end of the second bend pressing against the mounting bracket. In this design, the first bend, bending outward from the side wall of the inner liner, serves as elastic support and deformation guidance; the second bend, bending inward from the outside towards the side wall of the inner liner, has its end continuously pressing against the surface of the mounting bracket after it is in place, thereby providing guidance and buffering while achieving elastic self-locking and stable retention of the mounting bracket, further enhancing the reliability and vibration resistance of the connection.

[0016] Furthermore, the connecting lug and the balancing protrusion are located on the same side.

[0017] Furthermore, the distance between the elastic positioning part and the sensing hole and the balance hole is equal. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] See Figure 1-4 As shown, this utility model discloses an oven with a quickly detachable temperature sensor, including a body, an inner liner 1, and a temperature sensing component 2 mounted on the body. The temperature sensing component 2 includes a temperature sensor 21 and a mounting bracket 22. One side of the mounting bracket 22 has a sensing mounting hole 221 for mounting the temperature sensor 21, and the other side has a balancing protrusion 222. The inner liner 1 has a sensing hole 11 and a balancing hole 12 on its side wall. The sensing hole 11 is opposite to the sensing mounting hole 221, and the balancing hole 12 is opposite to the balancing protrusion 222. An elastic positioning part is formed on the outer side wall of the inner liner 1 between the sensing hole 11 and the balancing hole 12. The mounting bracket 22 is detachably fixed to the outer side wall of the inner liner 1 through the elastic positioning part. The temperature sensor 21 is mounted in the sensing mounting hole 221 and extends into the inner cavity of the inner liner 1 through the sensing hole 11. The balancing protrusion 222 cooperates with the balancing hole 12.

[0022] Furthermore, the elastic positioning part is an elastic cantilever piece 13, which is formed by partially punching and stretching the side wall of the inner liner 1, so that the elastic cantilever piece 13 has a fixed end connected to the side wall and a free end that can be elastically deformed. The cantilever piece of this solution has a fixed end connected to the side wall and a free end that can be elastically deformed; when the mounting bracket 22 rotates and squeezes the free end, the cantilever piece undergoes bending deformation, and after the bracket rotates into place, it rebounds due to the elastic restoring force of the material itself, thereby locking the mounting bracket 22.

[0023] Furthermore, the fixed end of the elastic cantilever plate 13 is its lower end, which is connected to the side wall of the inner liner 1; its free end is the upper end, and the mounting bracket 22 is inserted through the opening between the upper end and the side wall of the inner liner 1 during rotational installation. In this design, after the mounting bracket 22 is rotated into position, its lower edge or locking part is supported or limited by the lower fixed end of the cantilever plate. Since the fixed end is rigidly connected to the side wall of the inner liner and cannot move upward, a rigid downward stop is formed, which effectively prevents the mounting bracket 22 from falling out downward under gravity or vibration.

[0024] Furthermore, the mounting bracket 22 is plate-shaped, with a slot 224 on its lower center corresponding to the elastic cantilever plate 13. The slot 224 engages with the connection between the fixed end of the elastic cantilever plate 13 and the side wall of the inner liner 1. In this design, the two side walls of the slot 224 form a double-sided clamping effect on the root of the fixed end of the cantilever plate after engagement. This structure effectively restricts any slight movement or rotation of the mounting bracket 22 in the horizontal plane. At the same time, this clamping effect, combined with the fixed connection at the lower end of the cantilever plate, constitutes a stable anti-detachment structure, thereby significantly improving the mechanical stability of the connection while achieving quick assembly and disassembly.

[0025] Furthermore, the cross-section of the balancing protrusion 222 is a low-curvature arc surface. The shape of this design can provide a smooth guiding effect during installation, making it easy for the protrusion to slide into the balancing hole 12; at the same time, during disassembly, its gentle arc surface structure also facilitates smooth removal from the hole, thereby achieving auxiliary positioning and anti-rotation functions while supporting the rapid assembly and disassembly of the overall structure.

[0026] Furthermore, the balancing protrusion 222 is a protrusion integrally stamped with the mounting bracket 22. This solution uses a stamping process to form the balancing protrusion 222 and the mounting bracket 22 into a single structure, eliminating the parts and processes required for separate assembly.

[0027] Furthermore, the side of the mounting bracket 22 is provided with a connecting lug 223, which is perpendicular to the main body of the mounting bracket and forms an L-shaped structure.

[0028] Furthermore, the cross-section of the elastic cantilever plate 13 is a continuously bent curve, including a first bend 131 and a second bend 132. The first bend 131 is located at the lower part of the elastic cantilever plate 13, and its bending direction is outward from the side wall of the inner liner 1. The second bend 132 is located at the upper part of the elastic cantilever plate 13, and its bending direction is inward from the outside towards the side wall of the inner liner 1, with the end of the second bend 132 pressing against the mounting bracket 22. In this design, the first bend 131 bends outward from the side wall of the inner liner, serving as elastic support and deformation guidance; the second bend 132 bends inward towards the side wall of the inner liner, and its end continuously presses against the surface of the mounting bracket 22 after it is in place, thereby providing guidance and buffering while achieving elastic self-locking and stable retention of the mounting bracket 22, further enhancing the reliability and vibration resistance of the connection.

[0029] Furthermore, the connecting lug 223 and the balancing protrusion 222 are located on the same side.

[0030] Furthermore, the distances between the elastic positioning part and the sensing hole 11 and the balance hole 12 are equal. This invention utilizes the slight elastic deformation of the thin wall of the inner liner 1 by first inserting the probe and then rotating the bracket. This allows the main body of the mounting bracket 22 to engage with the elastic positioning part during rotation, achieving vertical locking. Simultaneously, the balance protrusion 222 on the other side engages with the balance hole 12 under pressure, achieving lateral limitation. This allows for a reliable and stable tool-free installation of the temperature sensor 21 in one operation. Compared to existing technologies, this invention eliminates the need for bolts, nuts, and other additional fasteners, changing the cumbersome installation method that requires two people working together and using tools. It enables rapid assembly and disassembly by a single person using simple rotation, improving installation and maintenance efficiency.
