Abstract
The utility model relates to a temperature controller, comprising a voltage reduction rectifying element, a control element and a mercury thermometer, characterized in that a plurality of conductor wires are inserted into capillary pipes respectively at the upper end and the lower end of the mercury thermometer, when temperature ascends to certain temperature control point of the upper end, the inserted conductor wires come in contact with the mercury to close circuit, electric relay or controllable silicon picks up or conducts, the controlled electric appliance works. The temperature controller has the advantages of simple structure, reliable performance, long service life, suited for controlling the temperature of all kinds of electric appliances, liquids or gases.
Description
The utility model relates to a kind of temperature controller, and particularly a kind of household electrical appliance temperature controller belongs to G05D23/24.
At present, household electrical appliance and the used temperature controller of other industry, structure more complicated mostly, cost height and serviceable life are shorter, thereby bring many inconvenience to the user.
The purpose of this utility model is to provide a kind of temperature controller of simple in structure, highly sensitive, long service life.
Temperature controller of the present utility model is to utilize existing mercury thermometer, draw a lead in the mercury thermometer lower end, this lead one end contacts with mercury face in the thermometer kapillary, and the other end and control element relay (or controllable silicon) link, after controlled electric appliance is serially connected in control element; Be provided with one or more temperature control point on mercury thermometer top, lead one end of drawing from each reference mark inserts the thermometer kapillary, and an end links by switch and step-down rectifier element.Circuit is connected when temperature rises to a certain institute controlling temperature, relay or controllable silicon adhesive or conducting, and controlled electric appliance is started working, thereby reaches the purpose of control temperature.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model outside drawing, and 1 is pilot lamp, and 2 is hand switch, and 3 is temperature automatically controlled switch, and 4 is thermoregulation knob, and 5 is incoming line, and 6 is output line.
Fig. 2 is the utility model structured flowchart, and 7 is controlled electric appliance, and 8 is control element, and 9 is the step-down rectifier element, and 10 is the 220V civil power, and 11 is mercury thermometer.
Fig. 3 is the utility model circuit diagram, and existing combined circuit figure describes principle of work of the present utility model.Draw a lead from the lower end of mercury thermometer 11, this lead contacts with mercury in the mercury thermometer 11, and an extension line and a control element relay 8 join; Be provided with three temperature control point A ', B ', C ' on the top of mercury thermometer 11, lead all inserts in the kapillary of thermometer 11, draws lead and passes through K switch
2Link K with step-down rectifier element 9
2Regulate by the thermoregulation knob on the controller 4 with the clutch of three temperature control point A ', B ', C '.After controlled electric appliance 7 is serially connected in relay 8, this controller incoming line 5 is inserted 220V civil power 10, when temperature rose to a certain institute controlling temperature, temperature control point lead contacted with mercury, and circuit is connected, relay 8 adhesives, and controlled electric appliance 7 is started working; During temperature below temperature is reduced to the reference mark, circuit is cut off, and relay 8 disconnects, and controlled electric appliance quits work.During the work of this controller, pilot lamp 1 is bright; When needing this controller temperature control, press temperature automatically controlled switch 3(K
1BC) if need controlled electric appliance 7 to start fast, then can press hand switch 2(K
1AB) just can.
The utility model is simple in structure, and long service life is suitable for controlling various electrical equipment, also can be used for the temperature of controlling liquid or gas.
Claims (3)
1, a kind of temperature controller, particularly a kind of temperature controller that is used for electrical equipment, by the 220V civil power, 10, formations such as step-down rectifier element 9, control element 8, controlled electric appliance 7, mercury thermometer 11, it is characterized in that drawing a lead in the lower end of mercury thermometer 11, this lead and control element 8 link, after controlled electric appliance 7 is serially connected in control element 8; On mercury thermometer 11 tops, be provided with one or more temperature control point, the lead of drawing from each temperature control point links by a switch and step-down rectifier element 9.
2, temperature controller according to claim 1 is characterized in that the control elements 8 of described control is relay or controllable silicon.
3, temperature controller according to claim 1 is characterized in that all need inserting the kapillary of thermometer 11 from the lead that thermometer 11 is drawn.
