Drinkware and plateware and active temperature control module for same

An active temperature control module can be used with drinkware and plateware devices. The drinkware can be a mug made of metal, and optionally coated with a ceramic material. The active thermal control module can optionally be removably coupleable to a surface of the drinkware or plateware device. The module can include at least one heating element that can thermally communicate with a surface of the drinkware or plateware device to thereby effect heat transfer through the base to food stuff (e.g., a solid food, a liquid food) in the drinkware or plateware device. The module can include at least one sensor configured to sense a parameter of the foodstuff, and at least one power storage element configured to provide power to the at least one heating element. The module can include control circuitry configured to control operation of the one or more heating elements, and a transceiver configured to transmit operating information of the module to a remote electronic device and to receive operating instructions from the remote electronic device. Optionally, the module can include a heat transfer pack that can thermally communicate with the at least one heating element, and which can be interposed between the at least one heating element and a surface of the drinkware or plateware device.

Liquid heating device and control method thereof

The invention discloses a control method of a liquid heating device. The method includes: acquiring target temperature, controlling the liquid heating device for heating for a first preset time, suspending heating for a second preset time and acquiring a temperature variation value of liquid between the first preset time and the second preset time after the liquid heating device heats the liquid for the first preset time, and further acquiring a power-off temperature point or concurrent heating time of the liquid heating device; controlling the liquid heating device to continue heating when the present temperature of the liquid in the liquid heating device is lower than the power-off temperature point, controlling the liquid heating device to suspend heating when the liquid temperature reaches the power-off temperature point, and when the present temperature of the liquid is higher than the power-off temperature point and lower than the target temperature, calculating the concurrent heating time and controlling the liquid heating device to heat the liquid continuously for the concurrent heating time until the liquid temperature reaches the target temperature. According to the control method, errors between the liquid heating temperature and the target temperature are able to be decreased, and temperature control is executed more accurately. Meanwhile, the invention further discloses the liquid heating device.
