Alternatively, the temperature threshold Tset may satisfy: 40-55 ℃; the temperature error can be controlled within 5 ℃ and 5 ℃.
In the embodiment of the invention, the temperature threshold Tset stored in the microprocessor unit can be limited to 40-55 ℃ at t, and the electric hot water bottle can be effectively prevented from being burnt out.

When the initial water temperature is lower than Tset, the heating control unit controls the heating unit to start heating, so that the real-time water temperature Tr meets the condition that Tset-Tr is less than or equal to 5, and the microprocessor unit can judge that the water temperature reaches a preset temperature value at the moment; when the initial water temperature is higher than Tset, the heating control unit controls the heating unit to stop heating, the real-time water temperature Tr is naturally cooled, and when the real-time water temperature Tr-Tset is less than or equal to 5, the microprocessor unit can judge that the water temperature reaches a preset temperature value at the moment.
In the embodiment of the invention, the error range is controlled within 5 ℃ and 5 ℃, and different initial water temperature states can be compatible.

The embodiment adds the heat preservation function on the basis of the first embodiment or the second embodiment.
Optionally, after stopping the heating function, the method may further include: the heat preservation function is automatically started.
Optionally, the holding temperature in the holding function may include: Tset-DeltaT-Tset-DeltaT; Δ T is a preset error.
In the embodiment of the invention, the electric hot water bottle can be kept warm when being heated to the preset warm keeping temperature, and the warm keeping temperature can be a temperature threshold Tset.
In the embodiment of the invention, the preset error Δ T can satisfy: less than or equal to 5 deg.C, for example, 3-5 deg.C may be selected.
In the embodiment of the invention, when the temperature detection unit detects that the difference value between the real-time water temperature Tr and the preset storage temperature Tset of the microprocessor unit is within 5 ℃ or 5 ℃, namely | Tset-Tr | < 5, the electric hot water bottle can start the heat preservation function, so that the real-time water temperature Tr always meets | Tset-Tr | < 5.
In the embodiment of the invention, in the heat preservation process, when the real-time water temperature Tr is greater than Tset, the heating control unit controls the heating unit to stop heating; when the water is not heated, the water temperature is higher than the ambient temperature, and the water temperature can naturally and slowly decrease due to the heat exchange; when the real-time water temperature Tr is lower than the preset storage temperature Tset, the heating control unit may control the heating unit to start heating, so that the water temperature rises.
In the embodiment of the invention, when the control method is adopted, the heating unit is started and stopped frequently, but the temperature precision is high. In order to improve the reliability and the service life of the heating unit, the frequency of the operation of the heating unit is reduced as much as possible. Therefore, the heat preservation precision is controlled within 5 ℃ or 5 ℃.
In the embodiment of the invention, the control process is as follows: when the real-time water temperature Tr is greater than the value of Tset and is higher than 5 ℃, the heating control unit can control the heating unit to stop heating; when the real-time water temperature Tr is less than or equal to Tset and is greater than or equal to 5 c after the water temperature decreases, the heating control unit may control the heating unit to start heating such that the real-time water temperature Tr is maintained within a range of Tset 5 c. According to the control scheme, the heating control unit controls the heating unit to stop, heat, stop and heat …, and the steps are repeated in such a way, so that the real-time water temperature Tr is ensured to be within 5 ℃ and 5 ℃ of the preset storage temperature Tset, namely, the requirement that the absolute Tset-Tr is less than or equal to 5 is met. In the embodiment of the invention, when the water temperature reaches the preset storage temperature Tset, heat preservation is carried out. Can provide hot water suitable for drinking at any time. The use experience of the user is improved.
In the embodiment of the invention, the heat preservation temperature is controlled according to the error of 5 ℃, so that the action frequency of the heating control unit can be reduced as much as possible under the condition of meeting the use experience of a user, the service life of the heating unit is prolonged, and the reliability of a product is improved.
In the embodiment of the invention, meanwhile, according to the control process, the working time of the heating unit is reduced, and the consumed electric energy in unit time is less, so that the aim of saving energy is fulfilled.
In the embodiment of the invention, the heat preservation temperature can be 40-55 ℃, and as the temperature difference between the water temperature and the ambient temperature is small, the heat exchange is slow, the energy required for maintaining the temperature is less, and the aim of further saving energy is achieved. For example: if the heat preservation temperature is higher, such as 80 ℃, the general environment temperature is between 5 ℃ and 30 ℃, and when the temperature is preserved at 80 ℃, the temperature difference between the water temperature and the environment is large, the heat exchange is fast, the water temperature is fast to drop, and the more energy is needed for maintaining the water temperature.
Example four
The embodiment further defines the heat preservation function on the basis of any embodiment.
In the embodiment of the invention, after the user selects the water boiling function, if the water is not used in time after boiling, the temperature can be automatically kept near the temperature threshold Tset.
In the embodiment of the invention, after the user starts the water boiling function, the microprocessor unit sends an instruction to the heating control unit, the heating control unit controls the heating unit to start heating, and the temperature detection unit detects the real-time water temperature Tr. When the real-time water temperature Tr reaches the boiling point, the micro-processing unit sends an instruction to the heating control unit, the heating control unit controls the heating unit to stop heating, and the water temperature can slowly drop due to the existence of heat exchange. Meanwhile, the temperature detection unit detects the water temperature Tr in real time. When the real-time water temperature Tr is reduced to a temperature threshold Tset stored by the microprocessor unit, namely, | Tset-Tr | -is less than or equal to 5, the microprocessor unit judges that the real-time water temperature reaches the heat preservation temperature at the moment, and starts the heat preservation function. The specific heat preservation process can be controlled according to the scheme of the previous embodiment.
In the embodiment of the invention, after water is boiled, the program automatically starts the heat preservation function, so that the water temperature can be maintained in a range suitable for drinking, and the use experience of a user is improved. For example, in winter, the ambient temperature is low, the water temperature drops quickly after the water is boiled, and if the heat preservation function is not started, the water temperature may be low, so that the user needs to heat the water again to a temperature suitable for drinking. After the functions are added, the user does not need to operate again, the water taking time is shortened, and the user experience is improved.
EXAMPLE five

Optionally, the method may further include: and in the process of executing the heat preservation function, displaying the heat preservation temperature and displaying the corresponding application of the liquid at the heat preservation temperature.
In an embodiment of the invention, the temperature value Tset stored by the microprocessor unit may be 40-55 ℃, typically 40-50 ℃ being suitable for brewing milk powder and 50-55 ℃ being suitable for brewing honey. When the temperature detection unit detects that the real-time water temperature is 40-50 ℃, an operation interface can display the (milk brewing) state to remind a user that the current temperature is suitable for brewing milk powder; when the temperature detection unit detects that the real-time water temperature is 50-55 ℃, honey can be displayed on the operation interface, and a user is reminded that the current temperature is suitable for brewing honey.
In the embodiment of the invention, the water temperature is displayed by adopting the number, so that a user cannot intuitively know the applicable scene of the current temperature. When the use scene that the temperature corresponds is shown on the operation interface of electric hot water bottle, the user just can be convenient select the temperature point, has greatly promoted the practicality of product for the machine is also more humanized.

The microprocessor unit collects the insulation temperature Tp used last time before the power-off of the user according to the signal of the input unit, and the microprocessor unit stores the insulation temperature Tp in the storage unit. After the next power-on, the microprocessor unit may first take the insulation temperature Tp out of the storage unit, and adjust the preset temperature Tset to Tp.
In the embodiment of the invention, different users have different use preferences, and the personal difference is larger. Users who like drinking tea generally use more than 80-100 ℃, and users who brew milk powder and honey generally use 40-55 ℃.
In the embodiment of the invention, the electric hot water bottle directly sets the heat preservation temperature to the temperature used by the user last time after being electrified according to the using habit of the user, thereby solving the hobbies of the individual user on a large program and improving the using experience of the product.
