Description

[Technical Field]

[0001] This utility model relates to a temperature controller structure, and more specifically to a snap-action high-sensitivity temperature controller structure. [Background Technology]

[0002] A snap-action thermostat is a thermostat that uses a bimetallic disc as its thermally sensitive actuating component. The bimetallic disc is housed in a closed space consisting of a housing or guide frame and a cover. When heated, the bimetallic disc's arc height begins to slowly decrease; until it reaches the set temperature, it snaps back, pushing a spring via an internal actuating rod, thus separating the moving contact from the stationary contact. It is widely used in various household appliances such as coffee makers, water dispensers, water heaters, microwave ovens, and electric heaters for temperature control or protection; it is a key safety device in heating appliances.

[0003] In the comparison of the above thermostat structures, during production and use, the bimetallic strip is prone to getting into the gap at the joint, causing the bimetallic strip to be pressed and clamped, which in turn affects the response speed of the bimetallic strip. Moreover, the assembly is complicated, the manufacturing time is long, and the cost is high. [Summary of the Invention]

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a temperature controller structure with fast response speed, convenient assembly, short manufacturing time, and cost savings due to the use of a temperature-sensing bimetallic strip.

[0010] The high-sensitivity temperature controller structure described above is characterized in that the positioning piece is a spring.

[0011] The high-sensitivity temperature controller structure described above is characterized in that the temperature sensing cap has an outwardly protruding cavity forming a limiting cavity.

[0012] The high-sensitivity temperature controller structure described above is characterized in that a base protrusion is provided on the outer side of the base, and the temperature-sensing cap is provided with an aluminum cap protrusion that matches the base protrusion. The aluminum cap protrusion is provided with a circular protrusion, and the circular protrusion matches the circular temperature-sensing bimetallic strip.

[0018] 2. The positioning piece of this utility model can be pre-riveted and fixed to the temperature sensing cap to form a pre-processed component, which will bring convenience of assembly during the production process, shorten the manufacturing time, and save costs.

[0019] 3. The temperature-sensing bimetallic strip of this utility model is confined in the limiting cavity. Compared with the traditional temperature controller structure, this avoids the temperature-sensing bimetallic strip from running into the gap of the joint during production and use, which would cause the temperature-sensing bimetallic strip to be pressed and clamped, thereby affecting the response temperature of the temperature-sensing bimetallic strip; thus improving the temperature-sensing reliability of the product.
