[0003] The Chinese invention patent application with publication number CN110448172A (application number 201910894333.6) "Device and drinking water equipment for heating drinking liquid", wherein the disclosed drinking water equipment uses a heater to heat the drinking liquid when it is in use. When the temperature reaches the set temperature, the liquid outlet pipe is controlled to open the liquid. This method of use will increase the waiting time of the user, and the user experience is poor.
[0004] In addition, there are water dispensers that directly discharge water after opening, and the control of the outlet water temperature is carried out by conventional temperature control means. The deviation of the set outlet water temperature is too large, and the corresponding user experience is also poor.

Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] Such as figure 1 As shown, the temperature control method for an instant electric appliance in this embodiment includes the following steps.
[0025] After the electrical appliance receives the liquid out command, it will work in three heating stages. However, in order to avoid damage to the electric appliance due to dry burning, when the electric appliance is used for the first time, before the first heating stage, at first inject liquid capable of filling the liquid flow path into the liquid flow path of the electric appliance. The liquid with the flow rate capable of filling the liquid flow channel is injected into the liquid flow channel of the electrical appliance by controlling the liquid input flow rate and the liquid input time. In addition, the first use mark can be built into the electrical appliance. If the pump body is con...

The invention relates to a temperature control method of an instant electric appliance. The method comprises the following steps: after receiving a liquid outlet command, an electric appliance performs work of three heating stages; in the first heating stage, full-power heating is conducted, and when the detected temperature of a liquid outlet end is close to the set temperature or the temperatureof the liquid outlet end is stabilized at the temperature lower than the set temperature, the second heating stage is conducted; in the second heating stage, the flow is adjusted, liquid is fed, full-power heating is conducted, and when the temperature T of the liquid outlet end is close to the set temperature T0, the third heating stage is conducted; in the third heating stage, the heating poweris adjusted according to a PID control method of the set temperature; and the flow and the heating power are gradually adjusted to reach the maximum heating power and the corresponding maximum flow.According to the temperature control method of the instant electric appliance, water can be discharged as soon as possible, it can be guaranteed that the deviation between the water outlet temperatureand the set temperature is small, and the comprehensive user experience can be improved.
Description
technical field [0001] The invention relates to a temperature control method of an instant electric appliance. Background technique [0002] For electrical appliances such as water dispensers, the existing water dispenser products have different heating modes of water storage heating and instant heating. For products with water storage heating and this heating method, in order to maintain the temperature, repeated heating is required, consuming At the same time, the heated water is prone to the problem of bacterial growth due to long-term storage. In addition, the water heated many times is not conducive to drinking water health. Therefore, instant water dispensers are becoming more and more popular, and they are cleaner and more hygienic to use. [0003] The Chinese invention patent application with publication number CN110448172A (application number 201910894333.6) "Device and drinking water equipment for heating drinking liquid", wherein the disclosed drinking water equi...
