The temperature measuring device 110 is disposed to the liquid heating container and configured to measure a temperature of the liquid in the container. Optionally, the temperature measuring device 110 is a temperature transducer.
The base part 200 is configured to supply the electric energy to the utensil part 100 through a cordless electric connector, the cordless electric connector realizes an electric connection when the utensil part 100 is placed on the base part 200 regardless of a relative angle relation between the utensil part 100 and the base part 200, and the base part 200 includes an electronic control device configured to control the electric heater. That is to say, when the utensil part 100 is placed on the base part 200, the cordless electric connector can supply the electric energy from the base part 200 to the utensil part 100 regardless of a relative angle between the utensil part 100 and the base part 200.

As illustrated in
More specifically, the cordless upper connector 120 is electrically connected to the electric heater. After the utensil part 100 cooperates with the base part 200, the electric energy can be transmitted to the electric heater through the cordless upper connector 120, and the electric energy is converted into thermal energy by the electric heater, so that the liquid in the container can be heated.
The cordless upper connector 130 for signal transmission is electrically connected to the temperature measuring device 110, so that the temperature signal can be transmitted to the cordless upper connector 130 for signal transmission after the temperature measuring device 110 measures the temperature in the container.
The cordless upper connector 120 and the cordless upper connector 130 for signal transmission are separate components. That is to say, the electric energy and the temperature signal are not transmitted by one component, and the transmission paths of the electric energy and the temperature signal are separated.
The base part 200 includes a base, the cordless lower connector 220, the cordless lower connector 230 for signal transmission and the electronic control device (not illustrated). The cordless lower connector 220 and the cordless lower connector 230 for signal transmission are disposed to the base part 200 separately, and the cordless lower connector 220 and the cordless lower connector 230 for signal transmission are electrically connected to the electronic control device.
In addition, the cordless lower connector 220 and the cordless lower connector 230 for signal transmission are separate components. That is to say, the electric energy and the temperature signal are not transmitted by one component, and the transmission paths of the electric energy and the temperature signal are separated.
When the utensil part 100 is placed on the base part 200, the cordless upper connector 120 cooperates with the cordless lower connector 220 to supply the electric energy to the utensil part 100, and the cordless upper connector 130 for signal transmission cooperates with the cordless lower connector 230 for signal transmission to transmit the temperature signal measured by the temperature measuring device 110 to the electronic control device.
An operation process of the cordless liquid heating apparatus 1000 will be briefly described.
First, the utensil part 100 is placed on the base part 200, in which case the cordless upper connector 120 cooperates with the cordless lower connector 220, and the cordless upper connector 130 for signal transmission cooperates with the cordless lower connector 230 for signal transmission. The electric energy can be transmitted to the electric heater through the cordless lower connector 220 and the cordless upper connector 120, the electric energy is converted into the thermal energy by the electric heater, and the liquid in the container can be heated. During the heating process, the temperature measuring device 110 disposed to the liquid heating container can measure the temperature of the liquid in the container, and transmit the measured temperature signal to the electronic control device through the cordless upper connector 130 for signal transmission and the cordless lower connector 230 for signal transmission. The electronic control device can operate in response to the measured temperature signal received. For example, when the temperature signal received by the electronic control device indicates that the temperature of the liquid in the container has reached a pre-set value, the electronic control device can control the electric heater to stop heating. When the temperature signal measured by the electronic control device indicates that the temperature of the liquid in the container does not reach a pre-set temperature value, the electronic control device can control the electric heater to continue heating.
In the cordless liquid heating apparatus 1000 according to embodiments of the present disclosure, the electric energy is transmitted from the base part 200 to the utensil part 100 through the cordless upper connector 120 and the cordless lower connector 220, the temperature signal measured by the temperature measuring device 110 is transmitted to the electronic control device through the cordless upper connector 130 for signal transmission and the cordless lower connector 230 for signal transmission, and the electronic control device operates in response to the signal received. The cordless upper connector 120 and the cordless upper connector 130 for signal transmission are separate components, and the cordless lower connector 220 and the cordless lower connector 230 for signal transmission are separate components, so that the transmission path of the electric energy and the transmission path of the signal are separated, when one of the cordless upper electric connector 120, the cordless upper connector 130 for signal transmission, the cordless lower connector 220, and the cordless lower connector 230 for signal transmission goes wrong, only the corresponding one needs to be maintained, thereby facilitating the maintenance of the cordless liquid heating apparatus 1000, and reducing the maintenance cost.
In some embodiments of the present disclosure, the utensil part 100 further includes a power adjusting device connected to the electric heater. The power adjusting device can adjust power of the electric heater, reducing or increasing the power of the electric heater, so that the cordless liquid heating apparatus 1000 can adapt to a plurality of modes and various emergencies.
Optionally, the power adjusting device is a triac (TRIode AC semiconductor switch). Three ends of the triac are connected to the electronic control device, the electric heater and a live line respectively.
During operation, a user selects a liquid temperature to be reached, or simply set to boil. The electronic control device then provides a signal to the triac so as to supply the electric energy to the electric heater, and the electric heater produces thermal energy to heat the liquid in the container. When the liquid in the container reaches the pre-set temperature, the electronic control device controls the triac to interrupt the energy supplied to the electric heater. When it is measured that there is no liquid in the container and the container is heated, the triac can cut off the energy supplied to the electric heater immediately.
According to some embodiments of the present disclosure, the base part 200 further includes a user interface connected to the electronic control device. The user interface can make it convenient for the user to operate, and can provide selections of the plurality of modes, such as a boiling mode, a sterilization mode, and a custom mode. The user can select a needed mode according to practical requirements.
