Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
Example 1
As shown in the attached figure 1, the intelligent electric kettle provided by the invention comprises an electric kettle body, wherein a pressure sensor is arranged at the bottom of the electric kettle body, a temperature sensor is arranged on the electric kettle body, the pressure sensor and the temperature sensor are both connected with an MCU, a heater is arranged in the electric kettle body, a power controller is connected to the heater, and the power controller is also connected with the MCU.
Obviously, a corresponding power supply is necessary to supply power to the whole system when the intelligent electric kettle works. Thus, fig. 1 shows a power supply connected to the power controller to power the power controller. The power supply modes of the MCU, the temperature sensor, the pressure sensor, etc. are known to those skilled in the art, and are not described herein.
As a more specific embodiment of the invention, the invention provides that the temperature sensor is arranged on the inner side wall or the outer side wall of the kettle.
Generally speaking, the measurement is more accurate when the kettle is arranged on the inner side wall of the kettle, but in the prior art, the kettle body can be made of metal, plastic, ceramic and the like, and the materials also have better heat conductivity, so the kettle can be arranged on the outer side wall of the kettle, and the technical effect of the invention is not influenced.
As another more specific embodiment of the present invention, the present invention provides that the temperature sensor is disposed between the lowest water level and the highest water level. The preferred scheme is as follows: the temperature sensor is arranged at the lowest water level.
Based on the whole technical idea of the invention, the pressure sensor is arranged for detecting the whole weight of the electric kettle body. When the water amount is too low, the weight is low, and the MCU controls the power controller to not work; similarly, when the water amount is too high, the weight is too high, and the MCU controls the power controller to be out of operation.
It can be seen that the weight range controlled by the MCU is set, the MCU substantially controls the lowest water level and the highest water level of the electric kettle body, only when the added water amount is between the lowest water level and the highest water level, the MCU controls the power controller to start working, and the electric kettle body starts to boil water.
Therefore, the optimal scheme of the temperature sensor provided by the invention is that the temperature sensor is arranged at the lowest water level of the electric kettle body. If the position of the temperature sensor is too high, the temperature sensor cannot measure the actual temperature of the water when the water in the electric kettle body is only added to the lowest water level; if the position of the temperature sensor is too low, the temperature sensor may be too close to the heater in the electric kettle body, and the measurement accuracy may also be affected.
In addition, the lowest water level and the highest water level can be marked by a scale line or other modes at the outer side of the electric kettle body, so that people can conveniently approximately estimate the added water amount when boiling water.
As another more specific embodiment of the invention, the temperature sensors are arranged in a plurality of groups along the periphery of the electric kettle body at the same height of the electric kettle body. By arranging a plurality of groups, when one or more temperature sensors have faults, the electric kettle body can still work normally.
As another more specific embodiment of the present invention, the power controller starts to operate or shuts down under the control of the MCU, and adjusts the power of the heater under the control of the MCU.

The main structure is the same as in example 1. The difference is that the embodiment is also provided with an air pressure sensor for measuring the atmospheric pressure in real time, the air pressure sensor is connected with the MCU, and the MCU is internally provided with an air pressure and boiled water temperature related function algorithm for obtaining the boiled water temperature under the current atmospheric pressure. And then the MCU accurately controls the water boiling process according to the temperature of the temperature sensor.

before water boiling begins, the pressure sensor collects the gravity of the intelligent electric kettle, the gravity data is sent to the MCU, the MCU controls the power controller according to the gravity data, the water quantity is too low or too high, the gravity collected by the pressure sensor is not in a preset gravity range, the power controller does not allow power to be output, and when the gravity collected by the pressure sensor is in the preset gravity range, the power controller allows power to be output, so that water boiling begins;
in the water boiling process, the MCU adjusts the power controller according to the water temperature, maximum power water boiling is adopted when the water temperature is lower, the water boiling power is gradually reduced when the water temperature reaches 60-80 ℃, and the water boiling power is reduced along with the increase of the water temperature. When the water is boiled, the water boiling power is between 5 and 20W. The power may be maintained for a period of time at this point, or the power controller may be turned off, ending the water boiling process.
FIG. 2 is a graph showing power and temperature curves during water boiling according to an embodiment of the present invention, in which the power is 800W immediately after water boiling, the water boiling power is rapidly decreased when the water temperature reaches 60 ℃, the water boiling power is gradually decreased as the water temperature increases, and finally, when the water is boiled (the water temperature is 100 ℃), the power is gradually decreased from 10W to 5W until the water boiling is finished, and the power is changed to 0W.
The power controller logic in the MCU according to an embodiment of the present invention is organized as follows:
this logic is merely that of one embodiment of the present invention. According to different conditions, the corresponding adjustment can be carried out.
The above description of the present embodiment is given with reference to the case where one is set to atmospheric pressure.
If the intelligent electric kettle of the embodiment 2 is adopted, the atmospheric pressure is measured in real time by the air pressure sensor when water is boiled, meanwhile, the air pressure sensor is connected with the MCU, and the MCU is internally provided with an air pressure and boiled water temperature related function algorithm to obtain the boiled water temperature under the current atmospheric pressure. And then the MCU accurately controls the water boiling process according to the temperature of the temperature sensor.
The air pressure sensor can be arranged at the positions of the kettle body, the handle, the kettle cover and the like of the intelligent electric kettle, and the intelligent electric kettle can be used for normal measurement without influencing normal water boiling.
Generally speaking, the water temperature for reducing the water boiling power is 20-40 ℃ lower than the boiled water temperature, so that the power output curve can be adjusted according to different boiled water temperatures.
Although the present invention has been described herein with reference to the illustrated embodiments thereof, which are intended to be preferred embodiments of the present invention, it is to be understood that the invention is not limited thereto, and that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure.
