Description

Technical Field

[0001] This utility model relates to a temperature control device with dual control combination. Background Technology

[0002] A thermostat, also known as a temperature controller, is a series of automatic control components that, based on changes in the ambient temperature, undergo physical deformation within the switch to produce certain special effects, resulting in either a conduction or a disconnection action. Currently, thermostats on the market are commonly used in household appliances and equipment with heating functions. Some heating equipment requires two temperature control modules: one to prevent dry burning and the other to regulate the temperature. This necessitates the use of two independent temperature control modules, which has the disadvantages of being inconvenient to install and occupying installation space.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a dual-control combined temperature control device, which includes a housing and two sets of temperature control modules mounted on the housing. The two sets of temperature control modules are arranged left and right at intervals. Each temperature control module includes a first terminal, a second terminal, a bimetallic strip, a push rod, a conductive sheet, and a spring. The bimetallic strip is in contact with the temperature sensing surface on the housing. The conductive sheet is disposed on the push rod, with one end of the push rod in contact with the bimetallic strip and the other end extending out of the housing. The spring is sleeved on the push rod and abuts against the conductive sheet, so that the conductive sheet connects to the first terminal and the second terminal. The first terminal and the second terminal extend out of the housing. When the bimetallic strip is deformed by high temperature, it can push the push rod to disconnect the conductive sheet from the first terminal and the second terminal.

[0006] In one or more embodiments, the top rod is provided with a step, and the conductive sheet abuts against the step and the spring respectively.

[0007] In one or more embodiments, the first terminal has a first conductive bump on the end that contacts the conductive sheet, and the second terminal has a second conductive bump on the end that contacts the conductive sheet.

[0009] In one or more embodiments, the first and second terminals are provided with wiring holes at the ends of the housing that extend out of the housing.

[0010] In one or more embodiments, the housing includes a bottom cover, a middle cover, and a top cover. The middle cover and the top cover form a first mounting area. The bimetallic strip is disposed in the first mounting area. The middle cover and the bottom cover form a second mounting area. The first terminal block, the second terminal block, the push rod, the conductive strip, and the spring are disposed in the second mounting area.

[0016] See appendix Figure 1-3 This application provides a dual-control combined temperature control device, which includes a housing and two sets of temperature control modules mounted on the housing. The two sets of temperature control modules are used for anti-dry burning and temperature regulation, respectively. The two sets of temperature control modules are arranged side by side. Each temperature control module includes a first terminal block 1, a second terminal block 2, a bimetallic strip 3, a push rod 4, a conductive sheet 5, and a spring 6. The housing includes a bottom cover 11, a middle shell 12, and a top cover 13.
