Abstract
The utility model relates to an electric heating temperature controlling energy-saving switch, composed of a temperature-sensing element, a transmission rod, an electrical contact mechanism, etc. The temperature-sensing element is formed by the fact that an elastic liquid storage chamber in which the temperature-sensing liquid is sealed is arranged in a metal shell. Through the expansion action that the temperature-sensing liquid is heated and vaporized, the transmission rod starts a moving plate in the electrical contact mechanism to cut off a heating power supply and \ or generate the audible and visual alarm signal. The utility model has the advantages of simple structure, large acting force, accurate and sensitive action, and obvious power saving effect, can be used for controlling different temperature ranges, and is suitable particularly for being used in the domestic electric heating appliance.
Description
The utility model relates to a kind of temperature control battery saving arrangement of electric heating appliance, especially a kind ofly is heated vaporized expanding and the thermally-actuated switch that moves with fluid.
Conventional electric heating utensil multipurpose electronic element or marmem sheet are controlled temperature, this class temperature detect switch (TDS) complex structure, and the installation and processing requirement is high, element is fragile, thereby its range of application is restricted.The disclosed a name of Patent Office of the People's Republic of China is called in " adjustable voltage-controlled thermostat " (application number 87206601) application documents and has proposed a kind of voltage-controlled thermostat that is made of reservoir compartment body, transducer, sealed pressing frame, sealed film, sealing ring, adjustable press box, spring, electrical contact and drive link etc., it utilizes the volume expansion of heated liquid by the cavity in the transducer, and the crush seal film also makes the drive link action.This construction of switch complexity has been used a plurality of potted components, and especially the local perseveration of sealed film, friction damage easily and leak.Because it only utilizes the volume expansion of liquid itself to move, its active force is less, and action sensitivity is not good enough.And when temperature raise above boiling point of liquid, the big pressure that vaporizing liquid produces may break through sealed film or dash and take off drive link.
The purpose of this utility model be to overcome above-mentioned deficiency and provide a kind of simple in structure, active force big, be active in one's movements, install electric heating temperature control battery-conserving switch easily.
The purpose of this utility model can adopt following structure to reach: place in a metal shell and encapsulating the elasticity reservoir compartment that boiling point is a temperature sensing liquid below 100 ℃, which is provided with one and extend the basic endoceliac drive link that insertion links to each other with metal shell, drive link top heads on and places basic endoceliac metal moving plate.Top cover inboard at matrix is provided with a spring, and it forces moving plate and basic endoceliac metal to decide loop contacts or disengaging.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with embodiment (accompanying drawing) the utility model is further described: placement one is encapsulating the temperature resistant rubber capsule 2 of ethanol liquid in the copper housing 1 of a garden cylindricality, its upper end has one to extend the drive link 3 that inserts in bakelite matrix 4 cavitys that are threaded with housing 1, and the upper end of drive link 3 heads on the copper moving plate 6 that places in matrix 4 cavitys.Also be provided with in matrix 4 cavitys and upper and lowerly copperly encircle 5 surely, the upper and lower end of the moving plate 6 that is placed in, and therefrom draw totally three in lead respectively.One bakelite top cover 8 is arranged at matrix 4 tops, and its inboard is provided with spring 7, and it forces moving plate 6 to encircle 5 surely and break away from last, and encircles 5 surely down and contacts.
The utility model can be used as the temperature control battery saving arrangement and/or the temperature control sound and light alarm switch of electric heating appliances such as electric cooker, insulating pot and electric water boiler.This battery-conserving switch is installed in top or top cover grip at electric heating appliance, with moving plate 6, down encircle 5 the lead of drawing surely and be connected in series in the electric heating line, moving plate 6, upward encircle 5 the lead of drawing surely and be connected in series in the acousto-optic alarm circuit.When electric heater unit rose to 100 ℃ with water temperature, water vapour was with housing 1, rubber bag tank 2 and the heating of ethanol liquid wherein, and the ethanol of boiling, vaporization acutely expands rubber bag tank 2 is heaved, and drive link 3 jack-up moving plates 6 is broken away from down encircle 5 surely, cut off heating power supply.When rubber bag tank 2 continues to expand, to encircling 5 surely when contact with last, connection sound and light alarm circuit sends sound and light signal to drive link 3 with moving plate 6 tops.Along with the reduction of temperature, rubber bag tank 2 shrinks gradually, and drive link 3 descends, and moving plate 6 is encircling 5 surely breaking away under the compressing of spring 7, and encircles 5 surely down and contact the connection heating power supply.When not needing temperature control, available collet covers on the housing 1.
Compared with prior art, the utlity model has following characteristics:
(1) simple in structure, volume is small and exquisite, and manufacturing requirements is not high;
(2) hotwork is firmly big, is active in one's movements, and temperature-sensitive, temperature control are accurate, and power savings is obvious;
(3) can control the temperature of different range by the liquid of changing the elasticity reservoir compartment;
(4) simple installation, not fragile, need not change the structure of electric heating appliance, do not influence the key property of former electric heating appliance yet.
Claims (4)
1, a kind of electric heating temperature control battery-conserving switch, comprise temperature-sensing element, drive link, electrical contact mechanism, it is characterized in that temperature-sensing element is made up of metal shell 1, the elasticity reservoir compartment 2 that encapsulating temperature sensing liquid, electrical contact mechanism by encircle 5 surely, moving plate 6 and draw lead and spring 7 is constituted.
2, electric heating temperature control battery-conserving switch according to claim 1 is characterized in that deciding ring 5 and can establish one to two, place moving plate 6 above and/or under the end.
3, electric heating temperature control battery-conserving switch according to claim 1 and 2 is characterized in that temperature sensing liquid is that boiling point is 70～90 ℃ a liquid, is preferably ethanol.
4, electric heating temperature control battery-conserving switch according to claim 3 is characterized in that elasticity reservoir compartment 2 is rubber bag tanks.
