Abstract
The utility model relates to a controllable temperature water heater alarmed by an electronic sound. The controllable temperature water heater alarmed by an electronic sound is composed of a heating element, a thermostat and a sound generator. The controllable temperature water heater alarmed by an electronic sound is characterized in that the thermostat is composed of a temperature controlled switch; the sound generator is composed of a sound integrated circuit and a piezoelectric sound sheet. The output end of the sound integrated circuit is connected with the piezoelectric sound sheet. Both ends of the temperature controlled switch are respectively connected in parallel with the power end of the sound integrated circuit first, and the both ends of the temperature controlled switch are connected in series with the heating element, and then connected with a power supply. When the temperature of hot water reaches a preset temperature, the sound generator emits a sound to tell a user. The utility model has high reliability. The utility model effectively overcomes the fault existing in the prior art that when water is boiled, no sound is emitted.
Description
The utility model relates to the temperature regulating device that a kind of electric heater is used, the temperature regulating device that particularly a kind of thermos bottle quick heater is used.
The temperature regulating device of using on the electrical equipment such as the quick heater that existing thermos bottle is used, electric kettle, electric heater mostly adopts mechanical vapour-pressure type sound equipment alarming device, and it can send the sound and inform that user's hot water has reached design temperature, thereby provides convenience to the user.But this device reliability is poor, water resistance easily takes place and not loud fault, causes electric heater dry combustion method accident.
In order to overcome above-mentioned deficiency, the purpose of this utility model provides a kind of improved temperature regulating device, particularly a kind of temperature control hot water apparatus with sound caution, and its reliability height can effectively overcome prior art and water resistance easily take place and not loud fault.
The purpose of this utility model realizes by following technical proposals.
The utility model is made up of electrothermal tube, temperature controller and acoustical generator, it is characterized in that temperature controller is made up of temperature detect switch (TDS), acoustical generator is made up of sound-producing integrated circuit and piezoelectricity sounding sheet, when heating-up temperature does not reach design temperature, the temperature detect switch (TDS) closure, acoustical generator is not worked; When heating-up temperature reached design temperature, temperature detect switch (TDS) disconnected, and the sound is sent in acoustical generator work, to inform the user.
The utility model is highly sensitive, the reliability height, and simple in structure, easy to use.
Below will do the utility model and describe in further detail by specific embodiment.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the structural drawing that thermos bottle quick heater of the present utility model is housed.
As Fig. 1, shown in Figure 2, the utility model is by electrothermal tube 1, temperature controller 2, and the acoustical generator composition, it is characterized in that temperature controller 2 is made up of temperature detect switch (TDS) K, acoustical generator is made up of sound-producing integrated circuit IC and piezoelectricity sounding sheet Y, the output terminal of sound-producing integrated circuit IC is connected with piezoelectricity sounding sheet Y, make its electric current of exporting certain intensity to promote piezoelectricity sounding sheet Y, send the alarm sound, the two ends of temperature detect switch (TDS) K earlier respectively with the power end A of sound-producing integrated circuit IC, the B parallel connection is connected with power supply with electrothermal tube R series connection back again, and the power supply of integrated phonation circuit IC is a voltage of taking from two power connection end points of temperature detect switch (TDS) K.As shown in Figure 2, piezoelectricity sounding sheet, sound-producing integrated circuit are placed on the circuit board 3, circuit board 3 and temperature detect switch (TDS) 2 are fixedly connected on respectively in the quick heater Plastic bottle plug 1.Its principle of work is, energized, and when water temperature did not reach design temperature, two contacts of temperature detect switch (TDS) K were short-circuit condition, and sound-producing integrated circuit IC two power end A, B no-voltage, piezoelectricity sounding sheet Y no current be not by working, i.e. silent; When water temperature reaches design temperature, two contacts of temperature detect switch (TDS) K are open-circuit condition, and sound-producing integrated circuit IC two power end A, B get electric, thereby the tone currents promotion piezoelectricity sounding sheet Y that exports certain intensity sends the alarm sound, to inform the user, hot water has reached design temperature.
