Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] A water temperature heating control method assisted by power feedback. After heating is started, the target water temperature and real-time water temperature are obtained, and heating is performed according to the theoretical power of the heating device; at the same time, the actual heating power of the heating device is detected, and the actual heating power is compared with the theoretical output. Power, to correct the heating power of the heating device. Make the actual heating power as close as possible to the theoretical output power and keep it stable to achieve the purpose of stable heating and keep the outlet water temperature stable and controllable.

[0041] The heating power of the heating device is corrected, specifically: the real-time voltage is calculated by detecting the actual heating power obtained, and the heating pow...

Abstract

The invention relates to a method and a device for controlling water temperature heating based on power feedback assisting. The method comprises the following steps of after starting heating, obtaining the target water temperature and real-time water temperature, and heating according to the theoretical power of the heating device; meanwhile, detecting the actual heating power of the heating device, comparing the actual heating power and the output theoretical power, and correcting the heating power of the heating device. The method has the advantages that in the heating process, the power detecting device is used for quickly detecting the power change caused by voltage sudden change, and timely feeding back to a controller, and the controller is used for making rapid response according to the current power, so as to maintain the stability of the outlet water temperature; the offset of the heater power and the change of voltage is finally represented as the change of the heater power; the technical problems of the prior art can be solved.

Description

technical field [0001] The present invention relates to a heating control method and device, more specifically, to a water temperature heating control method and device assisted by power feedback. Background technique [0002] In the field of instant smart toilets, the previous water heating control method is simply by obtaining the water inlet temperature, outlet water temperature, flow rate and the target water temperature to be heated, and calculating the heating required by controllers such as PID (Proportion Integration Differentiation) The power is controlled. In practical applications, on the one hand, there is a deviation between the actual power of the heating element and its rated power, and on the other hand, the fluctuation of the grid voltage makes the input voltage of the heating device deviate from its rated voltage, which in turn causes its actual power to deviate from the rated power, making the water temperature control accurate. Resilience and adaptabilit...
