Abstract
The utility model relates to a temperature control apparatus for an electric blanket or an electric bed, wherein a temperature sensor is fixed on the surface of a metal foil, the lead of the temperature sensor is connected with a temperature controller, the power supply input end of the temperature controller is connected with a power supply, and the output end of the temperature controller is connected with the power supply input end of the electric blanket or the electric bed. The temperature control apparatus employs the metal foil to enlarge the temperature measuring contact area of the temperature sensor, and converts the contact shape of the temperature sensor from a point shape or a bar shape to a plane shape, such that the contact area between the temperature sensor and the electric blanket or the electric bed is enlarged, and the real temperature state of the position of the electric blanket, where the temperature sensor is located is easily reflected, thereby being capable of obtaining real temperature signals, achieving an accurate control effect, and enabling people to more comfortably sleep on the electric blanket.
Description
Technical field:
The utility model relates to a kind of temperature control equipment, is a kind of for electric blanket or electrothermic kang temperature control equipment specifically.
Background technology:
At present, quite general with electric blanket or electrothermic kang heating.But present electric blanket or electrothermic kang are made of the method for electric filament disc on cloth mostly, and the distance of two heating wires that it is adjacent is wider, and generally more than 20mm, majority is not less than 40mm.Because the heating wire temperature is higher after the energising, sometimes surpasses 60 ℃, thereby sleep and easily produce the sensation of mouth parched and tongue scorched in the above.If heat in advance, in bed power supply is disconnected, not only can cool off after midnight, and the waste electric energy.Adopting temperature controller, temperature is carried out closed-loop control, is the effective ways that address this problem.But present existing temperature controller, its temperature sensor is bar-shaped or point-like, and surface area is less, if be placed directly on the wider electric blanket of line-spacing, its position is difficult to determine.Be placed on by the heating wire, the temperature signal of acquisition may be too high; Be placed on the centre position of two heating wire, the temperature signal of acquisition may be excessively low, thereby be difficult for obtaining real medial temperature signal, the control of the temperature that can not realize ideal.
Summary of the invention
Problem for existing electric blanket or electrothermic kang temperature control existence, the utility model provides a kind of and can obtain near electric blanket or the real temperature signal of electrothermic kang, reach accurate control effect, make human body sleeping more comfortable electric blanket or temperature control equipment of electrothermic kang on electric blanket.
Solve the problems of the technologies described above the concrete technical measures of taking: the temperature control equipment of a kind of electric blanket or electrothermic kang, comprise temperature controller and temperature sensor, it is characterized in that, temperature sensor is fixed on the surface of tinsel, the area of tinsel is not less than 10mm * 10mm, the lead-in wire of temperature sensor is connected with temperature controller, and the power input of temperature controller connects power supply, and the output terminal of temperature controller connects the power input of electric blanket or electrothermic kang.
The beneficial effects of the utility model: owing to adopting tinsel to enlarge the thermometric contact surface area of temperature sensor, the contact shape of temperature sensor by point-like, bar-shaped complanation shape, the area that contacts with electric blanket or electrothermic kang increases, the real state of temperature that more easily reflects electric blanket laying temperature sensor site, can obtain real temperature signal, reach accurate control effect, make human body sleeping more comfortable on electric blanket.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Be described with reference to the accompanying drawings structure of the present utility model.
The temperature control equipment of a kind of electric blanket or electrothermic kang, as shown in drawings, temperature sensor 2 usefulness epoxy resin or similar tackifier are bonded on the tinsel 3, also can screw, nut and sheet metal etc. be fixed on sensor 2 on the surface of tinsel 3, temperature sensor is the commercial goods, its type such as PT100 platinum resistance or KTY84 thermistor or 18B20 digital temperature sensor, concrete model is selected according to the design of temperature controller.The face shaping of tinsel 3 is square or rectangle is circular or oval and other various shapes, and the area of tinsel 3 is not less than 10 * 10mm, recommends size to be not less than 100 * 100mm, and thickness is not more than 1mm.The material of described tinsel 3 is Copper Foil or aluminium foil or iron sheet and other heat-conducting.The lead-in wire 4 of temperature temperature sensor 2 is connected with temperature controller 1,4 do not fractureed in order to protect lead-in wire, available one be riveted on crimp head 5 above the tinsel 3 will go between 4 be fixed on tinsel 3 above.The power input 6 of temperature controller 1 connects power supply, and the output terminal 7 of temperature controller 1 connects the power input 8 of electric blanket or electrothermic kang.
The tinsel 3 that will be loaded with temperature sensor during use is placed on above the heating wire optional position of electric blanket.Because self area of tinsel 3 increases, thereby the area that contacts with electric blanket or electrothermic kang also increases thereupon, the temperature of temperature sensor impression is neither contact the higher temperature of single heating wire, neither two lower temperature between the heating wire, but the medial temperature of electric blanket laying temperature sensor site.Thereby this real temperature signal can make controller reduce with on/off or with the voltage rising accurately, to satisfy the demand of comfort level.
Claims (1)
