Fig. 1 to 3 show schematic structural diagrams of a water kettle according to an embodiment of the present invention, and fig. 4 shows a control structure diagram of the water kettle according to an embodiment of the present invention. As shown in fig. 1 to 4, an embodiment of the present invention provides a water bottle, including:

the kettle body 1 is provided with a heating component 2 and a temperature controller 3 at the bottom, and the kettle body 1 is also provided with a temperature detector 4 for detecting the temperature in the kettle body 1 and a water level detector 5 for detecting the water level in the kettle body 1;

the circuit board 6 is arranged at the bottom of the kettle body 1 and is respectively electrically connected with the heating component 2, the temperature controller 3, the temperature detector 4 and the water level detector 5, and the temperature controller 3 can control the heating component 2 to work according to the temperature detected by the temperature detector 4 and the water level detected by the water level detector 5.

The embodiment of the utility model provides a kettle can carry out accuracy, reliable control through thermodetector 4 and water level detector 5's cooperation to heating element 2's heating to prevent that the too high hot water of temperature from spilling over the kettle, perhaps prevent that the kettle from burning futilely in order to protect the kettle, improve user experience.

In this embodiment, as shown in fig. 1 and fig. 2, the kettle body 1 includes a kettle body 11 and a kettle body bottom cover 12, an installation cavity 101 for installing the heating element 2 and the temperature controller 3 is defined between the kettle body 11 and the kettle body bottom cover 12, the heating element 2 is disposed near the bottom of the kettle body 11, one end of the temperature controller 3 is connected to the heating element 2, and the other end of the temperature controller 3 is connected to the kettle body bottom cover 12.

The kettle also comprises a base 7, a connector 71 is arranged on the base 7, and when the kettle body 1 is arranged on the base 7, the connector 71 penetrates through the kettle body bottom cover 12 to be connected with the temperature controller 3 so as to supply power for the temperature controller 3.

As shown in fig. 4, the circuit board 6 is a main control PCB board, and can receive the temperature signal detected by the temperature detector 4 and the water level signal detected by the water level detector 5, and generate a control signal based on the temperature signal and the water level signal, and send the control signal to the temperature controller 3.

The temperature controller 3 is used for controlling the kettle to execute temperature control operation according to the control signal sent by the circuit board 6, and a plurality of heating temperatures can be preset on the temperature controller 3 so as to control the heating component 2 to heat according to the temperature signal and the water level signal to reach the corresponding heating temperatures.

The circuit board 6 stores temperature thresholds and water level thresholds which can be reached by water in the kettle, wherein the temperature thresholds comprise a highest temperature threshold, a lowest temperature threshold and other preset temperature thresholds, and the water level thresholds comprise a highest water level threshold and a lowest water level threshold.

When the water level detector 5 detects that the water level in the kettle is lower than the minimum water level threshold, the temperature controller 3 does not control the heating assembly 2 to heat whether the temperature detected by the temperature detector 4 is lower than a preset temperature threshold (such as the minimum temperature threshold), so as to prevent dry burning. For example, when a temperature of 80 ℃ is detected in the kettle, and the maximum temperature threshold of the kettle can be 100 ℃, the water can be heated continuously to be boiled; however, at this time, the water level detector 5 detects that the water level in the kettle is lower than the minimum water level threshold, and if the water level in the kettle continues to be heated, a dry-heating phenomenon may occur, so that the circuit board 6 generates a control signal for not heating after receiving the temperature and water level signals, and sends the control signal to the thermostat 3, and the thermostat 3 controls the heating assembly 2 not to heat after receiving the signal.

When water level detector 5 detects that the water level in the kettle is higher than the highest water level threshold, no matter whether the temperature that thermodetector 4 detected is less than preset temperature threshold, temperature controller 3 is not controlled heating element 2 and is heated. That is, the minimum temperature threshold may not be set, and the minimum temperature of the water temperature may be determined based on the room temperature, for example, when the water temperature is lower than the room temperature or close to the room temperature, it may be determined that the water needs to be heated, and at this time, since the water level is higher than the maximum water level threshold, if heating is performed, it may not be determined when the water may overflow, and therefore, it may be determined whether the water needs to be heated only according to the water level, and the water overflow may be effectively prevented, and particularly, when the water temperature reaches a certain higher temperature, the hot water overflow may be effectively prevented from causing an injury to the user.

In other embodiments, a minimum temperature threshold above room temperature may be set, and the heating assembly 2 may be controlled to heat when the water level detector 5 detects that the water level in the kettle is above the maximum water level threshold and the water temperature is below the minimum temperature threshold. Because the water is heated when the initial temperature is lower and the water is not boiled much, the water can be heated even if the water level is higher than the maximum water level threshold value, and the heating efficiency of the heating component 2 can be ensured; meanwhile, a lower maximum temperature threshold (more than the boiling temperature) can be set, and the maximum temperature threshold is higher than the minimum temperature threshold higher than the room temperature, so that when the heating assembly 2 is heated to the maximum temperature threshold, the heating assembly 2 is controlled to stop heating in time, and the water higher than the maximum water level threshold cannot overflow.

When the water level detector 5 detects that the water level in the kettle is lower than the highest water level threshold and higher than the lowest water level threshold, and the temperature detected by the temperature detector 4 is lower than the preset temperature threshold, the circuit board 6 generates a control signal for heating and sends the control signal to the temperature controller 3, and the temperature controller 3 controls the heating assembly 2 to heat after receiving the signal.

The preset temperature threshold may be a minimum temperature threshold or other preset temperature thresholds. Other preset temperature thresholds can be temperature thresholds matched with a plurality of heating temperatures of the temperature controller 3 so as to judge whether water in the kettle meets the temperature thresholds of the corresponding heating temperatures, and then heating the heating component 2 in a sectional mode to improve the performance of the kettle. For example, a user may preset a holding temperature, and use the holding temperature as the temperature threshold of the heating temperature, and when the temperature in the kettle is detected to be lower than the holding temperature, the temperature controller 3 controls the heating assembly 2 to heat to reach the holding temperature.

According to the above, the embodiment of the utility model provides a temperature and the water level of kettle in the kettle just heat on satisfying the basis of predetermineeing the condition simultaneously, not only can prevent effectively that water from spilling over and the kettle from burning futilely, can also carry out accurate control to the heating of kettle to satisfy user's different user demands, improve user experience.
