Abstract

The utility model relates to a safe and efficient noodle boiling device. 220 V alternating current passes through an alternating current reduction voltage circuit, 60 to 70V alternating current is output, then, rectifying and wave filtering are carried out through a rectifying and wave filtering circuit, 50V, 42V or 36V alternating current is output after voltage stabilization through a voltage stabilizing circuit, and electricity is supplied to a positive temperature coefficient (PTC) heating disc for heating through being controlled by a controller. The controller comprises a micro control unit (MCU) control chip, a temperature data collection circuit, a water level data collection circuit, a press key circuit, a warning circuit and the like, temperature signals collected by a temperature sensor and water level signals collected by a water level sensor are transmitted to the MCU control chip, the MCU control chip controls whether the PTC heating disc begins to heat or not after judgment, an intermittent temperature programming method is adopted for heating, the MCU control chip controls the heating time of the PTC heating disc according to the set time of the press key circuit, or whether the PTC heating disc begins to heat or not is controlled according to the set temperature of the press key circuit and the temperature signals of the temperature sensor, and whether the warning circuit gives an alarm or not is controlled according to the water level signals of the water level sensor and the temperature signals of the temperature sensor.

Description

A kind of safe and efficient face device that boils

Technical field:

The utility model relates to household electrical appliance technical field, more specifically to a kind of have the face of boiling, to boil water, boil milk and boil the face that the boils device of the multiple function of chafing dish.

Background technology:

College student and the similar worker that stays up late; in study and work at ordinary times; occur reading a book to the late into the night through regular meeting; the phenomenon that perhaps rises late morning at this moment, is sought after energy supplement; eat one bowl of reeky rice; but close the door already, and also do not have in the dormitory and can only suffer from hunger always for the hot water that boils (bubble) instant noodles owing to the dining room.And, owing to need safety utilization of electric power in the dormitory building, can't use high-power electric appliance to heat up water, immersion heater, electric kettle etc. all belongs to electrical equipment violating the regulations.At this moment, if a low-power is arranged, meet the safety utilization of electric power principle, the face that the boils device that can use in dormitory will make everything problem be readily solved.

The utility model content:

The purpose of this utility model is exactly the deficiency at the existing product technology, and a kind of safe and efficient face device that boils is provided, it have the face of boiling, to boil water, boil milk and boil the multiple function of chafing dish, have temperature protection, water level protection and short circuit safety protection function simultaneously.

Technology solution of the present utility model is as follows:

A kind of safe and efficient face device that boils, comprise high insulation electric heating vessel, the calandria of high insulation electric heating vessel adopts the PTC heating plate, on the high insulation electric heating vessel temperature sensor and level sensor are installed, the 220V alternating current is through ac buck circuit output 60-70V alternating current, through the current rectifying and wave filtering circuit rectifying and wave-filtering,

export

50V, 42V or 36V alternating current after the mu balanced circuit voltage stabilizing again, the heating of PTC heating plate is given in via controller control power supply.

Controller comprises MCU control chip, temperature data acquisition circuit, waterlevel data Acquisition Circuit, key circuit, warning circuit etc.; The water level signal of the temperature signal of temperature sensor collection, level sensor collection flows to the MCU control chip, judges that by the MCU control chip whether back control PTC heating plate heats, and heats and adopts batch (-type) temperature programming method; Whether the MCU control chip is according to the heat time heating time of the setting-up time of key circuit control PTC heating plate, or heat according to the design temperature of key circuit and the temperature signal control PTC heating plate of temperature sensor; Whether report to the police according to the water level signal of level sensor and the temperature signal control warning circuit of temperature sensor.

Attaching has fuse on the power supply circuits of described PTC heating plate.

Described warning circuit is buzzer alarm circuit or light emitting diode warning circuit.

The beneficial effects of the utility model are:

1, it has the face of boiling (dumpling, won ton etc.), and is to boil water, boils milk, boils the function of chafing dish, and the temperature or the time of heating can be set by key circuit.

2, its safeguard protection is provided with: temperature protection---water boiling outage, the outage of container overtemperature etc.; Water level protection---container limit for height, limit low water level protection are as sound and light alarm etc.; Short-circuit protection--error protections such as-utensil short circuit generally adopt fuse.

3, it adopts low-voltage power supply, and is safe and reliable.
