Abstract
Disclosed is a digital display gas water heater. A timing inverted counting circuit comprises a mcu chip connecting with a logical gate circuit and a LED digital display displays the counting time to control the timing cutting of the gas. Therefore the flameout function of the gas water heater is realized. The users can observe residual time of the timer from the LED display, which is convenient to mastery the water using time.
Description
The utility model relates to a kind of digital display type gas heater.
Gas heater is the exigent product for civilian use of a kind of safety precautions, and is improper as the safety precautions of fruit product, might cause the generation of accident.Therefore, general gas heater all has defencive functions such as unexpected flame-out, low hydraulic pressure, low-voltage, anti-dry, anti-freeze.But people worry that still gas heater is because of the long generation that may cause accident service time continuously.
The purpose of this utility model is at above-mentioned deficiency, proposes a kind of digital display type gas heater, but it provide a kind of set, the gas heater of auto extinguishing in the time intuitively.
The utility model comprises gas heater body and regularly flame-out safety guard; regularly flame-out safety guard is made up of electric control box, microswitch, magnetic valve, LED nixie display etc., it is characterized in that electric control box is made up of firing circuit and timer conter circuit.
Above-mentioned timer conter circuit is made up of monolithic movement serial connection logic gates.
Regularly the realization that shows can be adopted along timing and two kinds of display packings of countdown, and the present invention adopts countdown numeral display mode, and purpose is to allow the user better grasp hot water service time.
The utility model is controlled the combustion gas timing turning off by singlechip chip string logic circuit and the digital demonstration of LED, and the control magnetic valve discharges, cuts off gas supply when arriving timing,
Thereby the flame-out function of the timing that realizes gas heater reaches the safeguard protection purpose; Owing to adopt the countdown numeral to show, can be observed the remaining time of timer from light-emitting diode display.
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Accompanying drawing 1 is the utility model circuit control principle figure.
Accompanying drawing 2 is the layout drawings that are electrically connected of the present utility model.
As shown in Figure 1, work as K switch
