Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and in particular to a bimetallic strip temperature control and positioning component. Background Technology

[0002] A thermostat is an automatic control element that, based on changes in the ambient temperature, undergoes internal physical deformation to produce specific effects, resulting in either a switching action (on or off). It is also called a temperature switch, temperature protector, or temperature controller. Thermostats have a wide range of applications, including in household appliances, motors, refrigeration, and heating systems, depending on the type.

[0003] Existing thermostats typically include a bimetallic strip, a conductive moving contact, and a stationary contact. The bimetallic strip has the characteristic of bending when heated. When the bimetallic strip deforms, it can cause the moving contact to move up or down, thereby causing the moving contact to separate or make contact with the stationary contact. This can easily lead to misalignment of the thermostat's fixed position inside the housing, resulting in deviations when the thermostat is closed and opened, thus affecting the closing and opening effect. Utility Model Content

[0004] The purpose of this utility model is to provide a bimetallic strip temperature control positioning component to solve the problem that existing temperature controllers typically include a bimetallic strip, a conductive moving contact, and a stationary contact. The bimetallic strip has the characteristic of bending when heated. When the bimetallic strip deforms, it can drive the moving contact to move upward or downward, thereby causing the moving contact to separate or contact with the stationary contact. This can easily lead to misalignment of the fixed position of the temperature controller inside the housing, resulting in deviations when the temperature controller is closed and opened, thus affecting the closing and opening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bimetallic strip temperature control and positioning assembly, comprising an assembly plate, an assembly groove on the top of the assembly plate, a through groove on the side of the assembly groove, and a positioning groove on the top of the assembly plate on the side of the assembly groove, a top plate snapped into the inner side of the assembly groove, a positioning plate fixedly connected to the side of the top plate and located inside the positioning groove, a central column fixedly connected to the bottom of the top plate, a temperature controller fixedly connected to the bottom of the central column, a bimetallic strip fixedly connected to the bottom of the temperature controller, and a return spring located on the top of the temperature controller on the outer side of the central column.

[0006] As a preferred technical solution of this utility model, the side of the assembly plate is provided with mounting grooves and positioning holes, and the number of positioning holes is four; the top side of the assembly plate is provided with mounting grooves and positioning holes, so that the thermostat at the bottom of the assembly plate can be stably installed in the appliance.

[0007] As a preferred embodiment of this utility model, a wiring hole is provided on the bottom side of the bimetallic sheet.

[0008] As a preferred embodiment of this utility model, the inner side of the positioning groove is provided with a slot, and the number of slots is two.

[0009] As a preferred embodiment of this utility model, a protruding rod is fixedly connected to the bottom of the positioning plate, and the protruding rod is engaged in the slot inside the positioning groove.

[0010] As a preferred technical solution of this utility model, a limiting arc plate is fixedly connected to the bottom inner side of the assembly groove, and the bottom of the limiting arc plate is located above the return spring; an assembly groove is opened at the top of the assembly plate, and the inner side of the positioning groove opened inside the assembly groove is engaged with the positioning plate on the side of the top plate. The temperature controller is installed on the top plate through the middle column. The bottom of the temperature controller is provided with a bimetallic strip, and the top of the temperature controller is provided with a return spring. The return spring is engaged with the bottom of the limiting arc plate at the bottom of the inner side of the assembly groove, so that the positioning plate at the top of the top plate is firmly engaged with the inner side of the positioning groove. This prevents the moving contact from moving up or down when the bimetallic strip deforms, thereby causing the moving contact to separate or contact with the stationary contact. This would easily lead to misalignment of the fixed position of the temperature controller inside the housing, which would easily cause deviation when the temperature controller is closed and opened, thus affecting the closing and opening effect.

[0011] As a preferred embodiment of this utility model, a copper sheet is provided on the top of the top plate, and the copper sheet is electrically connected to the top of the thermostat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features an assembly groove on the top of an assembly plate, with a positioning groove inside the assembly groove engaging with a positioning plate on the side of the top plate. The top plate is fitted with a thermostat via a central column. The thermostat has a bimetallic strip at its bottom and a return spring at its top. The return spring engages with the bottom of a limiting arc-shaped plate at the bottom of the assembly groove, ensuring the positioning plate at the top of the top plate is firmly engaged within the positioning groove. This prevents the bimetallic strip from deforming and causing the moving contact to move upwards or downwards, thus preventing separation or contact between the moving and stationary contacts. This avoids misalignment of the thermostat within the housing, which could lead to deviations in the closing and opening of the thermostat, affecting its effectiveness.

[0014] 2. This utility model has mounting grooves and positioning holes on the top and side of the assembly plate, which allows the thermostat at the bottom of the assembly plate to be stably installed inside the appliance. Attached Figure Description

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.

[0021] Please see Figure 1-4 This utility model provides a bimetallic strip temperature control and positioning assembly, including an assembly plate 1, an assembly groove 2 on the top of the assembly plate 1, a through groove 3 on the side of the assembly groove 2, and a positioning groove 4 on the top of the assembly plate 1 on the side of the assembly groove 2. A top plate 12 is snapped into the inner side of the assembly groove 2. A positioning plate 14 located inside the positioning groove 4 is fixedly connected to the side of the top plate 12. An intermediate column 11 is fixedly connected to the bottom of the top plate 12. A temperature controller 8 is fixedly connected to the bottom of the intermediate column 11. A bimetallic strip 9 is fixedly connected to the bottom of the temperature controller 8. A return spring 16 located on the top of the temperature controller 8 is provided on the outer side of the intermediate column 11.

[0022] The sides of the assembly plate 1 are provided with mounting grooves 6 and positioning holes 7, with four positioning holes 7 in total. The top side of the assembly plate 1 is also provided with mounting grooves 6 and positioning holes 7, which allows the thermostat 8 at the bottom of the assembly plate 1 to be stably installed inside the appliance. The bottom side of the bimetallic strip 9 is provided with wiring holes 10, and the inner side of the positioning groove 4 is provided with slots 5, with two slots 5 in total.

[0023] A protruding rod 15 is fixedly connected to the bottom of the positioning plate 14. The protruding rod 15 is engaged in the slot 5 inside the positioning groove 4. A limiting arc plate 17 is fixedly connected to the bottom inner side of the assembly groove 2. The bottom of the limiting arc plate 17 is located above the return spring 16. An assembly groove 2 is opened at the top of the assembly plate 1. The inner side of the positioning groove 4 opened inside the assembly groove 2 is engaged with the positioning plate 14 on the side of the top plate 12. The temperature controller 8 is installed on the top plate 12 through the intermediate column 11. A bimetallic strip 9 is provided at the bottom of the temperature controller 8. A return spring 16 is provided at the top of the temperature controller 8. The return spring 16 is engaged in the positioning groove 5 inside the positioning groove 4. The bottom of the limiting arc plate 17 at the bottom of the inner side of the assembly slot 2 can firmly lock the positioning plate 14 at the top of the top plate 12 into the inner side of the positioning slot 4, so as to prevent the bimetallic strip from deforming and causing the moving contact to move up or down, thereby causing the moving contact to separate or contact with the stationary contact. This would easily lead to misalignment of the fixed position of the thermostat 8 inside the housing, which would easily cause deviation when the thermostat 8 is closed and opened, thus affecting the closing and opening effect. The top of the top plate 12 is provided with a copper sheet 13, which is electrically connected to the top of the thermostat 8.

[0024] In practical use, firstly, the assembly plate 1 is installed inside the appliance using connecting screws. The top side of the assembly plate 1 is provided with mounting grooves 6 and positioning holes 7, which allows the thermostat 8 at the bottom of the assembly plate 1 to be stably installed inside the appliance. The top of the assembly plate 1 has an assembly groove 2, and the inner side of the positioning groove 4 is engaged with the positioning plate 14 on the side of the top plate 12. The thermostat 8 is installed on the top plate 12 through the intermediate column 11. The bottom of the thermostat 8 is provided with a bimetallic strip 9, and the top of the thermostat 8 is provided with a return spring 16. The return spring 16 is engaged with the bottom of the limiting arc plate 17 at the bottom of the inner side of the assembly groove 2, which allows the positioning plate 14 at the top of the top plate 12 to be firmly engaged with the inner side of the positioning groove 4. This prevents the moving contact from moving up or down when the bimetallic strip deforms, thereby causing the moving contact to separate or contact with the stationary contact. This would easily lead to misalignment of the thermostat 8 in the fixed position inside the housing, which would easily cause deviation when the thermostat 8 is closed and opened, affecting the closing and opening effect.
