Technical Field
[0001] This utility model relates to the field of electric oven thermostat technology, specifically an electric oven thermostat with temperature sensing and adjustment function. Background Technology
[0002] An electric oven is a kitchen appliance that uses radiant heat from electric heating elements to bake food. It is mainly used for baking bread, pastries, meat, and other foods. An electric oven mainly consists of a cabinet, heating elements, a thermostat, a timer, and a power adjustment switch. The thermostat is a device that automatically controls the circuit to open or close or adjusts the operation of the equipment based on changes in the temperature inside the oven. It is mainly used to achieve precise temperature regulation and energy-saving protection.
[0003] In response, Chinese patent application number CN202022465555.7 discloses a self-protecting, heat-preserving thermostat assembly, including a thermostat and a plastic protective box installed on the outside of the thermostat. The thermostat includes a mounting bracket, on the left side of which are mounted a ceramic ring, a stainless steel sheet, and a bimetallic strip. The stainless steel sheet and the bimetallic strip extend to the right, and a ceramic pillar connects the stainless steel sheet and the bimetallic strip. The plastic protective box has an opening on its left side and an opening on its top side, and is installed on the right side of the thermostat. This utility model is easy to install and can be widely used in small kitchen appliances, such as electric ovens, air fryers, and air fryer ovens. Under temperature control, the thermostat is unaffected by differences in the materials used in the oven, air fryer, or air fryer oven, or by environmental changes, ensuring stable product temperature, accurate baking temperature, improved food quality, extended the thermostat's lifespan, and reduced the risk of electrical conductivity between the thermostat and the external environment.
[0004] Most existing temperature controllers connect to the wiring inside the equipment by inserting connecting pieces and terminals. However, the existing connecting pieces are mostly smooth "L"-shaped metal pieces with only a round hole on the surface and no limiting mechanism. They are only connected by "C"-shaped clips on both sides of the terminal, resulting in poor connection strength. When the panel is removed from the housing, the shaking can easily cause the connecting pieces and terminals to loosen, causing the equipment to malfunction and causing inconvenience.
[0005] Therefore, in order to solve the above problems, a thermostat for an electric oven with temperature sensing and adjustment function is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a thermostat for an electric oven with temperature sensing and adjustment function, in order to solve the problem mentioned in the background art that most existing thermostats are connected to the circuit inside the equipment by plugging in the connecting piece and the connector. However, the existing connecting pieces are mostly smooth "L"-shaped metal pieces with only one round hole on the surface and no limiting mechanism. They are only connected by "C"-shaped clips on both sides of the connector, which has poor connection strength. When the panel is removed from the shell, the shaking can easily cause the connecting piece and the connector to loosen, resulting in the failure of the equipment and causing inconvenience.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an electric oven thermostat with temperature sensing and adjustment function, comprising: a cabinet, wherein a control panel is installed on the front side of the cabinet; A thermostat structure is mounted on the back of the control panel. The thermostat structure includes a mounting bracket, which is installed on the top surface of the control panel by screws. A connecting groove is provided on the side wall of the mounting bracket, and a rotating rod is installed on the front of the mounting bracket. A wiring piece is provided on the mounting bracket, and a slot is provided on the surface of the wiring piece. A connector is installed on the outer side of the wiring piece, and a card is integrally formed on the surface of the connector. A U-shaped groove is provided on the surface of the connector, and an elastic sheet is integrally formed on the inner side of the U-shaped groove. A locking block is stamped on the end surface of the elastic sheet. The thermostat structure is equipped with a protective structure, which includes a protective sleeve. The protective sleeve is fitted onto the upper outer side of the thermostat structure, and a connecting plate is integrally formed on the front side of the protective sleeve.
[0008] Preferably, the front end of the rotary rod penetrates the control panel.
[0009] Preferably, the card is clipped onto the surface of the connector, and the connector is in close contact with the connector.
[0010] Preferably, the slot is conical.
[0011] Preferably, the card block is engaged inside the card slot.
[0012] Preferably, the connecting plate is inserted inside the connecting groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model opens a conical slot on the connector and sets a locking block on the connector head. The locking block can be inserted into the slot under the elastic action of the elastic sheet, which can ensure the connection strength between the connector head and the connector. Furthermore, pressing the locking block inside the slot can push the locking block out from the inside of the slot, thereby pulling the connector head away from the outside of the connector, ensuring the ease of disassembly and assembly between the connector head and the connector, and improving the circuit connection stability of the device.
[0014] 1. This utility model features a thermostat structure. The connector and the terminal block are aligned, and then the connector is pushed towards the terminal block. The clip locks onto the surface of the terminal block, ensuring a tight fit between them. The terminal block pushes the locking block, causing the elastic plate to deform elastically within the U-shaped groove. As the connector moves outside the terminal block, the locking block slides along its surface. When the locking block moves to the inside of the groove, it loses contact with the terminal block and resets under the elastic force of the elastic plate. The locking block then locks into place within the groove, achieving a stable connection between the connector and the terminal block. The screws can then be tightened to secure the mounting bracket to the back of the control panel. The groove is conical; pressing the locking block inside the groove releases it, allowing the connector and terminal block to be separated. This facilitates maintenance of the thermostat structure, making it convenient and highly practical.
[0015] 2. By providing a protective structure, the connecting plate is secured inside the connecting groove, and the protective sleeve is stably installed on the upper outer side of the thermostat structure. This provides external protection to the thermostat structure, preventing damage from external forces. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4This utility model provides an embodiment of an electric oven thermostat with temperature sensing and adjustment function: The housing 1, control panel 11, mounting bracket 21 and rotary rod 23 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0020] An electric oven thermostat with temperature sensing and adjustment function includes: a cabinet 1, and a control panel 11 installed on the front side of the cabinet 1; A thermostat structure 2 is mounted on the back of the control panel 11. The thermostat structure 2 includes a mounting bracket 21, which is mounted on the top surface of the control panel 11 by screws. A connecting groove 22 is provided on the side wall of the mounting bracket 21. A rotating rod 23 is mounted on the front of the mounting bracket 21. A wiring piece 24 is provided on the mounting bracket 21. A slot 25 is provided on the surface of the wiring piece 24. A connector 26 is mounted on the outer side of the wiring piece 24. A card 27 is integrally formed on the surface of the connector 26. A U-shaped groove 28 is provided on the surface of the connector 26. An elastic piece 29 is integrally formed on the inner side of the U-shaped groove 28. The end surface of the piece 29 is stamped with a locking block 210. By opening a tapered groove 25 on the connector piece 24 and setting the locking block 210 on the connector 26, the locking block 210 can be inserted into the groove 25 under the elastic action of the elastic piece 29, which can ensure the connection strength between the connector 26 and the connector piece 24. Furthermore, by pressing the locking block 210 on the inside of the groove 25, the locking block 210 can be pushed out from the inside of the groove 25, thereby pulling the connector 26 away from the outside of the connector piece 24. This ensures the ease of disassembly and assembly between the connector 26 and the connector piece 24 and improves the circuit connection stability of the device. A protective structure 3 is installed on the thermostat structure 2. The protective structure 3 includes a protective sleeve 31, which is fitted onto the upper outer side of the thermostat structure 2. A connecting plate 32 is integrally formed on the front side of the protective sleeve 31.
[0021] Furthermore, the front end of the rotary lever 23 penetrates through the control panel 11.
[0022] Furthermore, the card 27 is clipped onto the surface of the terminal block 24, and the connector 26 is tightly fitted to the terminal block 24. The card 27 provides guidance and limitation for the fitting of the connector 26 on the outside of the terminal block 24.
[0023] Furthermore, the slot 25 is conical in shape, which allows the user to press the internal card block 210 in a position with a larger opening.
[0024] Furthermore, the locking block 210 is locked inside the slot 25, and the locking block 210 cooperates with the slot 25 to provide positioning for the installation of the connector 26 on the outside of the terminal block 24.
[0025] Furthermore, the connecting plate 32 is inserted inside the connecting groove 22, and the connecting plate 32, together with the connecting groove 22, provides a limit for the installation of the protective sleeve 31 on the outside of the thermostat structure 2.
[0026] Working principle: During installation, first align the connector 26 with the terminal block 24, then push the connector 26 towards the terminal block 24. The clip 27 will then lock onto the surface of the terminal block 24, ensuring a tight fit between the terminal block 24 and the connector 26. The terminal block 24 will push the locking block 210, which in turn causes the elastic piece 29 to elastically deform inside the U-shaped groove 28. As the connector 26 moves outside the terminal block 24, the locking block 210 slides along the surface of the terminal block 24. When the card block 210 reaches the inner side of the card slot 25, it loses the contact of the wiring piece 24 and can be reset under the elastic action of the elastic piece 29. The card block 210 can then be locked in the inner side of the card slot 25, realizing the stable connection of the connector 26 on the wiring piece 24. At this time, the screw can be tightened to fix the mounting bracket 21 to the back of the control panel 11, and the connecting plate 32 can be locked in the inner side of the connecting groove 22. The protective sleeve 31 is then stably installed on the outer side of the upper end of the thermostat structure 2, which can shield and protect the thermostat structure 2 from external force damage. The slot 25 is conical. By pressing the block 210 inside the slot 25, the block 210 can be pushed out from inside the slot 25, which releases the block 210 from the slot 25. This allows the connector 26 to be pulled apart from the terminal piece 24, facilitating the maintenance of the thermostat structure 2. The operation is convenient and highly practical.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
