Abstract
The utility model relates to a thermo-regulator pause switch, and is characterized in that a heater [2] is arranged on a thermo-regulator [1], the heater [2] is connected in series with the thermo-regulator [1], and the heater can be the electric-heat wire. The utility model is improved on the basis of the prior elements, and has the advantages of rational design, simple operation, low cost, sensitive control, and fast response, and the requirement for automatically and intermittently controlling in short time can be satisfied. The utility model can be spread and applied to household appliances, the product cost is effectively lowered, and the competitive power is enhanced.
Description
The utility model relates to a kind of electric control switch, particularly a kind of thermostat pause switch that utilizes the control of self-heating body heat content.
In the prior art, automatically control is commonly used to pause switch and thermoswitch, particularly on household electrical appliance, use, pause switch generally is made up of electronic circuit, and thermoswitch is the simplest to be bimetallic temperature controller, and electronic circuit is formed and pause switch control sensitivity, but its structure more complicated, cause its cost higher, and poor to environmental suitability, be subjected to useful life the electronic component quality influence big; Bimetallic temperature controller also has the function of pause switch, and it is simple in structure, and is cheap, and environmental suitability is strong, and long service life, its shortcoming are that response speed is slow, and accuracy is relatively poor, is not suitable for being applied in to required precision height, short occasion of control time at intermittence.
The purpose of this utility model is to provide a kind of improved thermostat pause switch for the shortcoming that overcomes above-mentioned prior art, improves response speed, and the realization short time is intermittently controlled, and reduces household electrical appliance control part cost.
The purpose of this utility model can realize by following technical measures: this pause switch has thermostat, be provided with heater on thermostat, heater can be heating wire, electric hot plate etc., and heater is connected with thermostat, during the thermostat conducting, heater is conducting simultaneously also.Use on control circuit, in thermostat energising time,, the heater heating temperature control device of also switching on makes its temperature reach temperature controlling point fast and disconnects, and realizes short time pause switch control.
Concrete structure of the present utility model and embodiment the following drawings provide:
Fig. 1 is the structure chart of thermostat pause switch;
Fig. 2 is the circuit diagram of thermostat pause switch.
The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, this pause switch has thermostat [1], be equiped with heater [2] on the housing of thermostat [1], heater is a heating wire, and resistance is generally 1～2 Ω, require the switch intermittent time short more, heating wire power is big more, otherwise, require the switch intermittent time long more, then heating wire power is more little, be decided according to the actual requirements, the housing of thermostat [1] is after insulation is handled, and the electric filament disc is on the housing of thermostat [1], heating wire is connected with thermostat, circuit diagram is seen Fig. 2, and R is a heating wire, and Kt is a thermostat, during the thermostat conducting, heating wire is conducting simultaneously also.Use on control circuit, in thermostat when energising,, the heating wire heating temperature control device of switching on simultaneously makes it reach temperature controlling point fast and disconnects, and when the thermostat temperature drops to certain value, thermostat is connected again from multiple above-mentioned action, realizes time pause switch control.
Reasonable in design of the present utility model is improved on existing element basis, and is simple, with low cost, it controls sensitive, and response speed is fast, can satisfy the requirement of short time interval-automatic control, apply on the household electrical appliance, effectively reduce product cost, enhance competitiveness.
Claims (2)
1, a kind of thermostat pause switch has thermostat [1], it is characterized in that being provided with on thermostat heater [2], and heater [2] is connected with thermostat [1].
