Abstract
The utility model relates to an automatic temperature control element for an electric water heater. The shape memory alloy is adopted as the temperature-sensing element material; the utility model is composed of a shape memory alloy element chamber and an electric chamber and is designed according to the principle that the stress restricts the phase change or the heat expansion generates the heat-sensing quick action effect. The utility model is suitable for the temperature control of the electric water heaters in different areas and can avoid effectively unfavorable outcomes that the water is not boiling because of the fact that the power is switched off, or the water is boiling but the power is not switched off. The utility model has the advantages of simple structure, low cost, and reliable operation.
Description
The utility model belongs to the automatic temperature control component in a kind of electric water-boiling device.
The main application of electric water-boiling device temp-controlling element is the circuit that can at once disconnect electric water-boiling device after water boils, the temperature control problem of present domestic electric water-boiling device is still among exploring, the commercially available electric water-boiling device of part does not have temperature regulating device, when water will seethe with excitement, must there be the special messenger to monitor, otherwise will causes waste of energy and other adverse consequences; Part electric water-boiling device uses electronic temperature control device, is by the senser temperature-sensitive, after temperature signal is become the signal of telecommunication and amplifies, promotes the executive component switching circuit, and complex structure, cost height, volume are big; Minority producer uses diaphragm capsule formula temperature control switch, and reliability is better, but costs an arm and a leg.Cheap electric water-boiling device temperature control switch all can not be realized the function that water boils and afterwards cuts off the power supply at once effectively at present, because the water boiling point of various places is slightly variant, there is the temperature control error to exist again, for example ± 2 ℃, 99 ℃ (somewhere water boiling temperatures) are transferred in the temperature control indication, if overproof, the outage temperature may be 101 ℃, causes the consequence of " water is opened and do not cut off the power supply "; Owe poor, actual outage temperature may be 97 ℃ of consequences that cause " outage water is not opened ".
The purpose of this utility model is to design and manufacture a kind of have assurance outage in time after water is opened, the temp-controlling element that again circuit is reclosed when water temperature drops to 85 ± 5 ℃.It " water is opened and do not cut off the power supply ", " outage water is not opened " two kinds of adverse consequencess definitely can not occur, also has insulation energising function, and the utility model volume is little, low cost product.
The utility model is to adopt marmem to make the temperature-sensing element material, utilizes stress restriction phase transformation or stress restriction expansion principle to realize temperature control.Its structure cut-away view as shown in the figure, 1 shape memory alloy spring, 2 slide bars, 3 biasing shell fragments, 4 compression springs, 5 moving contacts, 6 fixed contacts, 7 contact support bars, 8 are led steam vent, 9 leaks, shape memory alloy component chambers 10,11 electric panel rooms, 12 conducting strips.Wherein shape memory alloy spring 1 is to be that 50% to 50.2% Nitinol line processed coiling forms telescopic spring by nickel content, it is enclosed within the lower end of slide bar 2, the upper surface of slide bar 2 heads on conducting strip 12, the biasing shell fragment 3 that becomes by the phosphorus bronze sheet punching out be pressed in conducting strip 12 above, below conducting strip 12, supported by compression spring 4 again, end connecting circuit at conducting strip 12, the other end of conducting strip 12 is enclosed within on the contact support bar 7, compression spring 4 is between conducting strip 12 and moving contact 5, and be enclosed within on the contact support bar 7 moving contact 5, the lower end of the fixed contact 6 corresponding contact support bars 7 of ining succession and conducting strip 12 1 ends.Moving contact 5, fixed contact 6 are to adopt ag material to make.The utility model has electric panel room 11 and shape memory alloy component chamber 10, electric panel room 11 is made up of shell and conducting strip 12, biasing shell fragment 3, compression spring 4, moving contact 5, fixed contact 6, the contact support bar 7 of phenolic plastics compacting, wherein conducting strip 12, moving contact 5, fixed contact 6, contact support bar 7 built-up circuit paths.Shape memory alloy component chamber 10 is by shape memory alloy spring 1 and slide bar 2 and have the phenolic plastics shell of leading steam vent 8, leak 9 and form.Lead steam vent 8, leak 9, shape memory alloy component chamber 10 composition vapour paths.After the water boiling, vapours with certain pressure enters shape memory alloy component chamber 10 through leading steam vent 8, after indoor temperature surpasses a certain temperature, shape memory alloy spring 1 transfers stretched condition to by compressive state, its phase driving force transmits the pressure that has overcome biasing shell fragment 3 by slide bar 2, dynamic and static contact 5,6 is separated, reach the purpose of open circuit.After circuit disconnected, quantity of steam reduced gradually, and indoor temperature decreases, reach certain temperature after, shape memory alloy spring 1 transfers compressive state to by stretched condition, dynamic and static contact 5,6 contact again, the circuit connection.
The utility model is installed within the electric water-boiling device insulation interlayer, it is led and leads vapour on steam vent 8 and the electric water-boiling device and connect mouth and link to each other, leak 9 is connected with the base plate of electric water-boiling device, steam condensate (SC) in the shape memory alloy component chamber 10 can be discharged outside the casing, two conducting strips 12 just can normally be used in the place in circuit respectively.
Claims (2)
1, the automatic temperature control component in a kind of electric water-boiling device is made up of shape memory alloy component chamber 10 electric panel rooms 11, it is characterized in that:
A, shape memory alloy component chamber 10 are to be installed in by the lower end that shape memory alloy spring 1 is enclosed within slide bar 2 to have between the plastic casing of leading steam vent 8, leak 9;
An end of conducting strip 12 and compression spring 4 all are enclosed within on the contact support bar 7 among b, the electric panel room 11, the other end connecting circuit of conducting strip 12, moving contact 5, fixed contact 6 corresponding contact support bar 7 lower ends and conducting strip 12 1 ends of ining succession respectively, wherein conducting strip 12, moving contact 5, fixed contact 6, contact support bar 7 built-up circuit paths.
2,, it is characterized in that shape memory alloy spring 1 is is the flexible springs that 50% to 50.2% Nitinol wire-wound system forms by nickel content by the described device of claim 1.
