Abstract

The utility model discloses a dry burning prevention, auto alarm, multi-function electric heating boiled water barrel, comprising an over temperature fuse, a heating board and a temperature regulator which are connected in series in sequence; the utility model is characterized in that the space between the end B of 220V commercial power and the temperature regulator is connected in series with a dry burning prevention temperature controller; and the dry burning prevention temperature controller is adhibited at the middle of the bottom of the heating board. The utility model also comprises an auto alarm circuit. In the case of a dry burning instance, the temperature of the heating board rises rapidly. When the temperature exceeds the preset temperature value, the dry burning prevention temperature controller is disconnected, thus, the loop is disconnected; then, the temperature is maintained, guaranteeing that the temperature is not raising on, thereby, the heating board is secure from being burnt out. Meanwhile, a warning tone is given by the auto alarm circuit. Thereby, the utility model has the advantages that with the main loop being controlled by the temperature controller and an auto alarm function, guaranteeing that the heating board is secure from being burnt out, thus, the service life of the heating board can be prolonged. The utility model is a new model electric heating boiled water barrel.

Description

The automatic alarm multifunction electrothermal water boiling of anti-dry bucket

Technical field

The utility model relates to the electrothermal water boiling bucket, especially relates to the automatic alarm multifunction electrothermal water boiling of a kind of anti-dry bucket.

Background technology

The electrothermal water boiling bucket is that a lot of government departments and institutions, school, enterprise are with being the instrument that boils water.At present, most of common electric heating boiled water pails all do not have anti-dry burning device, in case user's improper use or electrical equipment go wrong, under the ignorant situation of user dry-fire condition take place, and heating board just burns out easily, also just can't continue to heat up water, and brings very big inconvenience to the user.

Summary of the invention

The purpose of this utility model is to provide a kind of and adopts temperature controller to control total loop, guarantees that heating board is not burnt out, has warning function, can prolong the heating board automatic alarm multifunction electrothermal water boiling of the anti-dry bucket in service life.

The purpose of this utility model is achieved in that the utility model comprises staving, panel, bung, Chuan Lian overheating fuse successively, heating board and thermoregulator, the A end of the idle termination civil power 220V of overheating fuse, be parallel with at the energising two ends of heating board mutual series connection resistance and in order to the indication heated condition bulb, be parallel with at the two ends of thermoregulator mutual series connection resistance and in order to the indication keeping warm mode bulb, between the B of civil power 220V end and thermoregulator, be in series with an anti-dry temperature controller, and the anti-dry temperature controller is attached to the bottom center of heating board.

The utility model also comprises automatic alarm circuit.

The utility model is owing to be in series with an anti-dry temperature controller between the B of civil power 220V end and thermoregulator, and the anti-dry temperature controller is attached to the bottom center of heating board, like this when dry-fire condition takes place, the temperature of heating board rises rapidly, and when temperature surpassed preset temperature value (about 200 degree), the anti-dry temperature controller will disconnect, make the loop disconnect, keep this temperature then, guaranteed that temperature does not continue to rise, thereby heating board can not burnt out.The utility model only adopts an anti-dry temperature controller just well to prevent the generation of the dry combustion method of electrical equipment, makes the electrothermal water boiling bucket except heating up water, and can also cook congee, boil soup, and control is simple, with low cost.Send chimes of doom under the situation that automatic alarm circuit can disconnect in that dry combustion method, anti-dry temperature controller Yin Gaowen take place, remind the user in time to pull out plug, the disconnected power supply that goes, thus the protection heating board can not burnt out.Therefore the utlity model has the employing temperature controller and control total loop, guarantee that heating board is not burnt out, reports to the police automatically, can prolong the heating board advantage in service life, is a kind of new electrically heating boiled water pail.

Description of drawings

Fig. 1 is a circuit theory schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model comprises staving, panel, bung, Chuan Lian overheating fuse F successively, heating board R and thermoregulator S1, the A end of the idle termination civil power 220V of overheating fuse F, be parallel with at the energising two ends of heating board R mutual series connection resistance R 1 and in order to the indication heated condition bulb L1, be parallel with at the two ends of thermoregulator S1 mutual series connection resistance R 2 and in order to the indication keeping warm mode bulb L2, between the B of civil power 220V end and thermoregulator S1, be in series with an anti-dry temperature controller S2, and anti-dry temperature controller S2 is attached to the bottom center of heating board R.

The utility model also comprises automatic alarm circuit, automatic alarm circuit is by transformer T, rectifier ZL, integrated regulator IC, resistance R 3, capacitor C 1, C3, polar capacitor C2, C4, relay J and buzzer SPK form, one termination overheating fuse F of the primary coil of transformer T and the public connecting end of heating board R, the other end is taken over control the public connecting end of dry combustion method temperature controller S2 and thermoregulator S1, the positive-negative input end of secondary coil two termination rectifier ZL, the positive output end of the input termination rectifier ZL of integrated regulator IC, the negative output terminal of ground connection termination rectifier ZL, the output of integrated regulator IC links to each other with earth terminal with the coil of relay J series connection back, capacitor C 1 and polar capacitor C2 are connected in parallel between the input and earth terminal of integrated regulator IC, capacitor C 3 and polar capacitor C4 are connected in parallel between the output and ground of integrated regulator IC, connect with buzzer SPK back and be connected in parallel on the primary coil two ends of transformer T of the normally closed switch J1-1 of relay J; Resistance R 3 is connected in parallel on the primary coil two ends of transformer T.
