Abstract
The utility model relates to an automatic call device for a water heater, belonging to the area of household electrical appliances, comprising an attaching plug, an electric resistance bar, a heat-variable resistor, a loudspeaker, a plastic waterproof protective shell and an integrated circuit plate. The utility model is characterized in that the plastic waterproof protective shell is positioned on the top of the electric resistance bar, the integrated circuit plate is arranged in the plastic waterproof protective shell, the heat-variable resistor is positioned above the plastic waterproof protective shell from which the attaching plug is led out, the integrated circuit plate is composed of a voltage-regulator diode, a diode, an electric resistance, a capacity, a heat-variable resistor, a slide rheostat and an operational amplifier. The principle of the utility model is using temperature-sensing warning circuit to measure water temperature, when the temperature reaches the set value, an alarm will be sounded. The utility model has the advantages that the production is simple, the utilization is convenient, the utility model can prevent fire and produce positive benefits in safeguarding people's life and property and maintain social order.
Description
Technical field
This is practical to relate to a kind of automatic warning immersion heater, belongs to field of household appliances, refers in particular to a kind of immersion heater that can report to the police automatically, and it can adapt to the daily use of people.
Technical background
In daily life, immersion heater is small household appliances easily, because it is simple in structure, economical and practical, in daily life, promote widely and use, but because immersion heater on the market is with the work of resistance heating principle, it will work always as long as electricity is arranged, people are usually careless and inadvertent in the daily life, lead to many fire incidents, make the people life property safety suffer damage, and this product can satisfy original demand that makes things convenient for of people, increase the water warning function that boils and can be timely when water boils, have reminded the user in time to pull out power supply, avoided disaster hidden-trouble.
Summary of the invention
For fear of with overcome above-mentioned deficiency, the novel purpose of this use provides a kind ofly can remind the user to pull out the automatic warning immersion heater of attaching plug immediately when can water boiling, so that when water boils, remind very much the user in time to pull out attaching plug, avoid because the careless and inadvertent fire that causes.
The realization the technical solution of the utility model is:
By attaching plug, resistor rod, thermistor, loud speaker, plastics waterproofing protective case, surface-mounted integrated circuit are formed automatic warning immersion heater, it is characterized in that settling the plastics waterproofing protective case on the resistance caput, surface-mounted integrated circuit is in the plastics waterproofing shell, and thermistor exposes the plastics waterproofing protective case, draw attaching plug in the plastics waterproofing protective case, surface-mounted integrated circuit is by voltage stabilizing didoe, diode, resistance, electric capacity, thermistor, slide rheostat, operational amplifier is formed.The principle of utility model is to utilize the temperature control warning circuit to measure the temperature of water, when temperature reaches the value of setting, sends warning.
The utility model has the advantages that, make simply, easy to use, can prevent that fire from taking place, will not lose for ensureing people's lives and properties, safeguard that civil order produces positive benefit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model schematic diagram,
Fig. 2 is the utility model circuit theory diagrams.
As shown in the figure, number in the figure is represented respectively: 1. attaching plug 2. resistor rods 3. thermistors 4. loud speakers 5. plastics waterproofing protective cases 6. surface-mounted integrated circuits 7. voltage stabilizing didoes 8. diode R1. resistance R 2. resistance R 3. resistance R 4. resistance R 5. resistance R 6. resistance R 7. resistance R 8. resistance C1. capacitor C 2. electric capacity Rt. thermistor Rp. slide rheostat VT1. operational amplifier VT2. operational amplifiers
Embodiment
As shown in the figure, surface-mounted integrated circuit (8) is by loud speaker (4) voltage stabilizing didoe (6) diode (7), resistance (R1), resistance (R2), resistance (R3), resistance (R4), resistance (R5), resistance (R6), resistance (R7), resistance (R8), electric capacity (C1), electric capacity (C2), thermistor (Rt), slide rheostat (Rp), operational amplifier (VT1) and operational amplifier (VT2) are formed.Utilize thermistor (Rt) to measure temperature, when if dut temperature surpasses the temperature of slide rheostat (Rp) setting, the then comparator output that constitutes via first operational amplifier (VT1), if surpass monitoring temperature, then the comparator that constitutes via first operational amplifier (VT1) is output into high resistance, the open collector circuit, so the monostable multi resonant oscillator work that is made of second operational amplifier (VT2), loud speaker (4) the warning reminding people that pipes notes subsequently.
During use, the resistor rod (2) of immersion heater is put into thermos, the plug that plugs in (1) treats that water when boiling loud speaker (4) can send the warning reminding people that pipes and note pulling out attaching plug (1).
Claims (1)
1. the immersion heater of reporting to the police automatically comprises: attaching plug (1), resistor rod (2), thermistor (3), loud speaker (4), plastics waterproofing protective case (5), surface-mounted integrated circuit (6), it is characterized in that on resistor rod (2) head, settling plastics waterproofing protective case (5), integrated circuit (6) is in the plastics waterproofing shell (5), and thermistor (3) exposes plastics waterproofing protective case (5), draws attaching plug (1) in plastics waterproofing protective case (5), surface-mounted integrated circuit (8) is by loud speaker (4) voltage stabilizing didoe (6) diode (7), resistance (R1), resistance (R2), resistance (R3), resistance (R4), resistance (R5), resistance (R6), resistance (R7), resistance (R8), electric capacity (C1), electric capacity (C2), thermistor (Rt), slide rheostat (Rp), operational amplifier (VT1) and operational amplifier (VT2) are formed.
