Abstract
The utility model discloses a buzzing circuit after water of an electric kettle boils. The buzzing circuit comprises a water boiling power interruption temperature controller, a buzzer and an electric heater, wherein the water boiling power interruption temperature controller is connected with the buzzer in parallel with one end of parallel connection connected with a line A of a power supply and the other end of parallel connection connected with one end of the electric heater, and a line B of the power supply is connected with the other end of the electric heater. With the buzzing function, the control circuit of the electric kettle can inform a user in the first time after water boils, thus being beneficial to the timely shut or interruption of the power supply by the user to prevent the water from being heated for a plurality of times and reducing unnecessary waste of electric energy.
Description
Technical field
The utility model relates to a kind of insulating pot control circuit, more particularly, relates to a kind of insulating pot water and opens the back buzz circuit.
Background technology
In the prior art, common insulating pot control circuit is to control water temperature by temperature controller, after the water in the insulating pot is opened, temperature controller can be cut off the electricity supply, but after the temperature of water-in-kettle is reduced to uniform temperature, temperature controller can be communicated with power supply again and cause water by heating for multiple times, so not only a large amount of wastes electric energy, and water also can form we thousand boiling water often said.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of novel control circuit, points out people in time to cut off the electricity supply by buzzing, to remedy the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model be achieved in that a kind of insulating pot water open the back buzz circuit, include water and cut-off electric temp. comtrol arrangement, buzzer and electric heater, described water cut-offs electric temp. comtrol arrangement and buzzer is in parallel, one end of its parallel connection links to each other with power supply A line, its other end in parallel is connected with a wherein end of electric heater, and power supply B line links to each other with the electric heater other end.
What described water cut-off electric temp. comtrol arrangement and buzzer place of being in parallel and electric heater wherein is provided with anti-dry heating temperature controller between the end.
Described power supply A line and water cut-off between electric temp. comtrol arrangement and the buzzer place of being in parallel and are provided with anti-dry heating temperature controller.
The two ends of described electric heater are parallel with indicator lamp.
In the application of reality, circuit is connected power supply, and water is when heating, and water cut-offs electric temp. comtrol arrangement and is in conducting state, carries out heating work, and buzzer is not because impedance has electric current more greatly by being in cut-off state; Water temperature reaches the regulation requirement, and water has been opened, and water cut-offs electric temp. comtrol arrangement tripping outage, is open-circuit condition, and this moment, buzzer constituted the loop with electric heater, and the buzzer acquisition electric current sound of sounding a buzzer is pointed out.
Beneficial effect after the employing technique scheme is: the utility model insulating pot control circuit, the buzzing function that is had, can notify the user in the very first time after water is opened, being beneficial to the user in time closes or cuts off the electricity supply, in order to avoid water is by heating for multiple times, and reduce unnecessary waste of energy.，
Description of drawings
Fig. 1 opens the circuit connection diagram of back buzz circuit for the utility model insulating pot water.
Fig. 2 is the circuit connection diagram of another embodiment of the utility model.
Wherein, 1 power supply A line, 2 anti-dry heating temperature controllers, 3 water cut-off electric temp. comtrol arrangement, 4 electric heaters, 5 indicator lamps, 6 buzzers, 7 power supply B lines.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.
As shown in Figure 1, insulating pot water of the present utility model is opened the back buzz circuit, include water and cut-off electric temp. comtrol arrangement 3, buzzer 6 and electric heater 4, described water cut-offs electric temp. comtrol arrangement 3 and is in parallel with buzzer 6, one end of its parallel connection links to each other with power supply A line 1, its other end in parallel is connected with a wherein end of electric heater 4, and power supply B line 7 links to each other with electric heater 4 other ends.
What described water cut-off electric temp. comtrol arrangement 3 and buzzer 6 places of being in parallel and electric heater 4 wherein is provided with anti-dry heating temperature controller 2 between the end.
As shown in Figure 2, another embodiment of the present utility model, described power supply A line 1 and water cut-off between electric temp. comtrol arrangement 3 and buzzer 6 places of being in parallel and are provided with anti-dry heating temperature controller 2.
The two ends of described electric heater 4 are parallel with indicator lamp 5.
Insulating pot water of the present utility model is opened the back buzz circuit, sets up anti-dry heating temperature controller by dual mode, can play the effect of security protection.
The above only is a preferable possible embodiments of the present utility model, is not in order to limit scope of the present utility model.
