Abstract
An ultra-long wire-shaped temperature-sensing flexible element relates to a heating wire element for a flexible heater in the domestic electric appliance field, and the element consists of an inner core wire, a power heating wire, an inner insulation layer, a sensing wire and an outer insulation layer, wherein the power heating wire spinally winds on an insulation core axle; the inner insulation layer covers the power heating wire; the sensing wire winds on the inner insulation layer spinally in the reverse direction; and the outer insulation layer covers the sensing wire. The utility model has the advantage that the temperature changes of a flexible heater are real-timely transmitted to a control device of the flexible heater by the sensing wire, thereby realizing the dual protection of over temperature. The utility model is applicable to flexible heaters of various types.
Description
Technical field
The utility model relates to the heater wire element that the flexible warming appliance in a kind of household appliance technical field is used.
Background technology
The flexible thermal kind of thread elements is the heart element of flexible warming appliance in the household appliance technical field.Present flexible warming appliance most ofly adopts common flexible thermal kind of thread elements, and in use the overheating problem of Fa Shenging is difficult to be found, and its consequence is when overtemperature reaches the fusing point of lining and burning-point, will cause fire, causes the person and property loss.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, designs a kind of linear temperature sensing flexible member of overlength with sensing function.
The linear temperature sensing flexible member of overlength of the present utility model is made up of internal core wire, power heater wire, inner insulating layer, sense line and external insulation layer, described power heater wire is wound on the insulation mandrel in the shape of a spiral, inner insulating layer is covered on the power heater wire, the sense line reverse acting spiral is wound on the inner insulating layer, and external insulation layer is covered on the sense line.In the process of power heater wire heating, the temperature transfer of power heater wire is delivered to sense line with temperature signal for the inner insulating layer that covers thereon, again by the real-time control device that this temperature signal is delivered to flexible warming appliance of sense line during work.Described sense line is a kind of metal alloy wires with positive temperature coefficient, and when it experienced temperature, its impedance raises with temperature to be increased.The control device of flexible instrument detects this variation, will fit the break-make of electric current in the physical control power heater wire, thereby has controlled the temperature of flexible warming appliance, makes it the overtemperature problem not to take place.In addition, the another kind effect of inner insulating layer is after the sense line control device of flexible instrument is malfunctioning, when reaching the fusing point of inner insulating layer material owing to the lasting rising of temperature, and the inner insulating layer fusing, its outer sense line is short-circuited with its interior power heater wire.This short-circuit signal is delivered to the control device of flexible instrument, and control device also can thoroughly be cut off the electricity supply, thereby has avoided the generation of overheating problem.
The utility model has the advantages that the suitable control device that is delivered to flexible warming appliance on the spot of variations in temperature when flexible warming appliance being used, realized duplicate protection for overtemperature with sense line.
Further specify content of the present utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 uses schematic diagram for present embodiment.
Embodiment
In the accompanying drawing 1, power heater wire 2 is wound on the insulation mandrel 1 in the shape of a spiral, and inner insulating layer 3 is covered on the power heater wire, and sense line 4 reverse acting spirals are wound on the inner insulating layer, and external insulation layer is covered on the sense line, has constituted the linear temperature sensing flexible member of overlength.
Accompanying drawing 2 has provided a kind of application in flexible heat generation device.Under the normal condition, power heater wire two ends generate heat by electric current, are delivered to sense line by inner insulating layer.Sense line detects temperature in real time and feeds back to the temperature detecting unit 6 of controller, if temperature surpasses set point, and Thermal Cutoffs 7 fusing and the loops of cutting off the electricity supply.In addition, after the sense line temperature detecting unit was malfunctioning, the line elements temperature rose to inner insulating layer 3 plastic moltings, sense line and the short circuit of power heater wire, and this short-circuit signal is directly delivered to Thermal Cutoffs, makes it to cut off the electricity supply.Just because of this sensing effect of line elements has realized the duplicate protection for overtemperature.
Claims (2)
