Problems solved by technology

[0003] The temperature limit protection structure of the above-mentioned double-tank electric water heater needs to adopt two manual reset temperature limiters, including two membrane boxes and two switch box components, and the two switch box components must be connected in series and fixedly, which is large in size and Difficult to install, many procedures, high production cost, the most important thing is that each manual reset temperature limiter has a certain temperature limit temperature error, when two manual reset temperature limiters are used in series, the overall temperature limit temperature error is larger than that of a single manual reset temperature limiter. The reset temperature limiter is much larger, thereby reducing the effect of temperature limit protection

Embodiment Construction

[0023] The present invention is described in further detail by the following examples.

[0024] see Figure 1-Figure 6 As shown, a double-probe pressure manual reset temperature limiter is composed of a switch box assembly 107 and a temperature sensing assembly. The switch box assembly 107 is composed of a switch base 9 and a bipolar switch. The bipolar switch consists of a double-moving contact 11. Composed of double moving contacts 13, double static contacts 14, double moving terminals 10, and double static terminals 15; the temperature sensing component is composed of a bellows 108, a capillary and a temperature sensing cylinder, and the bellows 108 is composed of a diaphragm 7 and a bellows The seat 8 is welded by circular seam. The temperature-sensing cylinder of the temperature-sensing component includes a first temperature-sensing cylinder 1 and a second temperature-sensing cylinder 3. The capillary includes a first capillary 2 and a second capillary 4. The two tempera...

Abstract

A double-probe pressure type manual reset temperature limiter comprises a switch box assembly and a temperature sensitive assembly, the temperature sensitive assembly is provided with a first temperature-sensitive cylinder and a second temperature-sensitive cylinder, first and second capillary tubes are welded and connected to a film box in a penetrated manner to form an enclosed pressure-equivalent system which is penetrated, and a liquid working medium is filled into the system. The temperature limiter is mainly applied to an electric water heater of a structure with double inner containers, and can realize temperature-limiting protection for the two inner containers of the electric heater via only one switch box assembly and one film box, it is ensure that the temperatures of the two inner containers are consistent, the production cost is reduced, and the precision of temperature-limiting protection is improved.

Description

technical field [0001] The invention relates to the technical field of manual reset temperature protectors, in particular to a double-probe pressure type manual reset temperature limiter. Background technique [0002] At present, the electric water heater industry is developing a kind of "double tank fast heating" electric water heater. The double tank fast heating electric water heater adopts two horizontal upper and lower inner tanks connected in parallel and connected with each other. The lower electric heating tube, the upper inner tank is provided with a vertical water outlet pipe, the outlet pipe passes through the lower inner tank and the heat insulation shell from the upper inner tank, the inlet of the water outlet pipe is located at the upper part of the upper inner tank, and the lower inner tank is provided with an inlet A water pipe, the water inlet pipe passes through the heat-insulating shell from the bottom of the lower inner tank to communicate with the outsid...
