Embodiment 1

[0052] Such as figure 1 , 2 As shown, the output control module 29 is a power output control circuit that can control the output voltage of the power supply. The input end of the power output control circuit is connected to the output end of the temperature difference calculation and comparison module 28, and the power The output terminal of the output control circuit is connected to the power supply 30, and the output terminal of the power output control circuit is connected to the fast heater 3 at the same time.

[0053] figure 1 , 2 4, the instant electric kettle includes a body 1, a bottom plate 5 is provided at the bottom of the body 1, and the upper part of the body 1 is closed by a top cover 22 to form a cavity 17; a water tank 2 can be placed behind the body 1; A waste water tray 6 can be placed under the front and bottom of the waste water tray 6. The waste water tray 6 is covered with a cup tray 25. A cup can be placed on the cup tray 25 to receive the hot water from the...

Embodiment 2

[0079] Such as figure 1 , 3 As shown, the output control module is a flow adjustment control circuit, the input end of the flow adjustment control circuit is connected to the output end of the temperature difference calculation and comparison module 28, and the output end of the flow adjustment control circuit is connected to the power supply 30 is connected, and the output end of the flow adjustment control circuit is connected to the pump 4 at the same time. The pump 4 can adjust the flow rate to adjust the flow rate to change the temperature of the hot water outlet.

[0080] Such as figure 1 , 3 , Shown in 5. In the instant electric kettle of this embodiment, the method for controlling the heating water state is:

[0081] After the circuit is turned on, the pump 4 sends the cold water 26 in the water tank 2 to the fast heater 3 through the cold water pipes 8, 10, and the fast heater 3 heats up quickly. The temperature sensor 20 transmits the detected real-time temperature value...

Embodiment 3

[0086] Such as figure 1 , 2 3. As shown in 3, the output control module is a combination control circuit composed of a power output control circuit that can control the output voltage of the power supply and a flow adjustment control circuit. The input end of the combination control circuit and the The output terminal of the temperature difference calculation and comparison module 28 is connected, the output terminal of the combined control circuit is connected with the power supply 30, and the output terminal of the combined control circuit is connected with the rapid heater 3 and the pump 4 at the same time.

[0087] In the instant electric kettle of this embodiment, the heating state control method is: simultaneously adjusting the flow rate of the pump and the power of the rapid heater to change the temperature of the hot water outlet.

Abstract

The invention discloses an instant electric kettle, which comprises a machine body; the machine body is provided with a bottom plate; an upper end of the machine body is sealed by a top cover, so a cavity is formed; the cavity accommodates a pump of which one end is communicated with a water tank and the other end is communicated with a quick heater; the quick heater is provided with a water inletand a hot water outlet, and a vapor discharging port is positioned in a hot water outlet path of the quick heater and can also be positioned on the upper part of the quick heater and higher than thehot water outlet or a liquid water level; and the instant electric kettle quickly adjusts the power of the quick heater or the flow rate of the pump or simultaneously adjusts the power of the quick heater and the flow rate of the pump according to the hot water outlet temperature so as to ensure that the hot water outlet temperature meets the requirements of people. After connecting a power sourcefor a few seconds, the instant electric kettle can instantly heat cold water into hot water of which the water outlet temperature meets the requirements of the people or boiling water of which the expected maximum temperature value can reach 100DEG C, has stable and steady outlet water, energy and electricity conservation, and strong practicability, and meets the requirements of consumers.

Description

Technical field [0001] The invention relates to an electrical appliance, in particular to an instant electric kettle provided with an electronic circuit to control boiling water temperature and heat preservation temperature and a control method thereof. Background technique [0002] At present, most electric kettles heat the cold water in the water container into boiling water at one time and it takes at least a few minutes to boil the cold water. If the boiling water in the container cannot be used up all at once, the water will be cooled. It is a waste of water resources when it reaches room temperature; if it is not the same day’s boiled water in a thermos bottle, it is similar to water left in the air for a long time, it will produce bacteria; if the boiled water is boiled again, the nitrous acid content in the water will exceed the standard, causing Human body is damaged. The re-boiled water is still a concentrated solution of harmful substances such as heavy metals and arse...
