Abstract
A novel temperature sensor of an electric cooker is mainly composed of an aluminum cap (1), a spring (2), a fixing plate (3), a hot melting fuse wire (5), an outer support (6), hot melting fuse wires (7), a thermistor, an inner support, a thermistor signal line and a ground connection line. The thermistor is fixed on an inner top portion of the aluminum cap (1) through the inner support, and the two hot melting fuse wires (7) are fixed in the aluminum cap (1) and located below the thermistor. The novel temperature sensor is simple in structure, easy to install and capable of substantially improving safety of the electric cooker.
Description
Technical field
The utility model relates to a kind of electric cooker temperature sensor, is a kind of electric cooker thermistor temperature sensor that dual anti-dry hot melt insurance is installed specifically.
Background technology
At present, the electric cooker thermistor temperature sensor is made up of thermistor, hot melt insurance, aluminium lid, support, spring and lead etc. mostly.The insurance of thermistor, hot melt is installed in the aluminium lid, is fixed by support, picks up when separating with heat-generating disc when interior pot, and sensor is upspring under the spring force effect; Sensor aluminium lid shirt rim contacts with heat-generating disc, and as this moment occurring unexpected energising heating heat-generating disc, the sensor aluminium lid can raise with the heat-generating disc temperature; Put into when interior pot and to contact with heat-generating disc when cooking work, aluminium lid separates with heat-generating disc, and sensor aluminium lid top contacts with the interior the bottom of a pan; By pot bottom temperature in the thermosensitive resistance measurement, through the control circuit control that realizes cooking, when control circuit break down cause in during pot dry combustion method; The sensor aluminium lid can raise with interior pot temperature and rise, and therefore, electric cooker is no matter pot is put in having or not; When unexpected temperature rise appearred in heat-generating disc, the sensor aluminium lid all can raise with the heat-generating disc temperature, when the temperature of aluminium lid is elevated to the temperature spot that makes hot melt insurance fusing; Hot melt insurance fusing makes the main circuit outage, and heat-generating disc stops heating, thereby protects heat-generating disc and prevent that fire failure from taking place.But the reliability of hot melt insurance at present also is not high especially, needs further to improve the security of electric cooker.
Summary of the invention
The purpose of the utility model provides a kind of novel electric cooker temperature sensor that has dual fail-safe, and it is simple in structure, installs easily, can significantly improve the electric cooker security.
A kind of novel electric cooker temperature sensor that the utility model provides; Mainly contain aluminium lid, spring, fixed head, hot melt insurance electric wire, support arm, hot melt insurance, thermistor, inner support, thermistor signal line and ground wire; Thermistor is fixed on the aluminium lid inner top by inner support; Hot melt insurance has two, by support arm be fixed in the aluminium lid, be positioned at thermistor below.
Thermistor is installed in the high temperature resistant sleeve pipe of thermistor the inside, and the hot melt insurance is installed in hot melt and insures high temperature resistant sleeve pipe the inside, is drawn with external control circuit with hot melt insurance electric wire by the thermistor signal line respectively to be connected.
Two hot melt insurances are drawn outside by internal series-connection or by electric wire and are connected in series.
The beneficial effect of the utility model is: need not change original electric cooker thermistor temperature sensor external structure, install easily.Because the insurance of two hot melts is installed, have only two all defective in qualityly just accident can occur through series circuit, reliability significantly improves.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the left view of the utility model.
Fig. 3 is the structural drawing that the utility model is applied to electric cooker.
Embodiment
See figures.1.and.2; A kind of novel electric cooker temperature sensor that the utility model provides, this temperature sensor 8 have aluminium lid 1, spring 2, fixed head 3, hot melt insurance electric wire 5, support arm 6, hot melt insurance 7, thermistor 13, inner support 9, thermistor signal line 11 and ground wire 12.Fixed head 3 molds two vertical guiding pin, and the end of pin is sheared out position-limited claw, and aluminium lid 1 has pilot hole, and the fixed head guiding is worn into the aluminium lid pilot hole, and it is spacing to do the crooked back of 90 degree by position-limited claw, and fixed head and aluminium lid form spring groove, the spring 2 of packing into.Thermistor 13 is fixed in the aluminium lid inner top by inner support 9; Hot melt insurance 7 has two, draw outside by internal series-connection or by electric wire to be connected in series, by support arm 6 be fixed in the aluminium lid 1, be positioned at thermistor 13 below; Like this; The upper strata is that thermistor 13 lower floors are two hot melt insurances 7 in aluminium lid 1, and thermistor 13 is installed in the high temperature resistant sleeve pipe of thermistor 10 the insides, and hot melt insurance 7 is installed in hot melt and insures high temperature resistant sleeve pipe 4 the insides; Draw with external control circuit by thermistor signal line 11 and hot melt insurance electric wire 5 respectively and be connected, play the safeguard protection effect.
Referring to Fig. 3, the fixed head 3 of this temperature sensor 8 is loaded on electric cooker 14 liner bottom centre, aluminium lid 1 outstanding heat-generating disc 15 center surfaces.Pick up when separating with heat-generating disc when interior pot, this temperature sensor 8 is upspring under the spring force effect, and the aluminium lid shirt rim of this temperature sensor 8 contacts with heat-generating disc; As this moment occurring unexpected energising heating heat-generating disc, the aluminium lid of this temperature sensor 8 can raise with the heat-generating disc temperature, puts into and contacts with heat-generating disc when cooking work when interior pot; Aluminium lid separates with heat-generating disc, and the aluminium lid top of this temperature sensor 8 contacts with the interior the bottom of a pan, by pot bottom temperature in the thermosensitive resistance measurement; Through the control circuit control that realizes cooking, when control circuit break down cause in during pot dry combustion method, the aluminium lid of this temperature sensor 8 can rise with interior pot temperature rising; Therefore, electric cooker is no matter pot is put in having or not, when unexpected temperature rise appears in heat-generating disc; The aluminium lid of this temperature sensor 8 all can raise with the heat-generating disc temperature, and when the temperature of aluminium lid was elevated to the temperature spot that makes hot melt insurance fusing, hot melt insurance fusing made the main circuit outage; Heat-generating disc stops heating, thereby protects heat-generating disc and prevent that fire failure from taking place.
