Control method for avoiding over-temperature false alarm of instant heating type intelligent closestool

Abstract

The invention relates to an instant heating type intelligent closestool, discloses a control method for avoiding over-temperature false alarm of the instant heating type intelligent closestool, and solves the problem that the use of a user is influenced by software false alarm caused by over-temperature water temperature when heating is started due to fluctuation of power supply voltage. The control method comprises the following steps that a, in the self-checking process after the instant heating type intelligent closestool is powered on, the current alternating current input voltage is detected and fed back to an MCU; b, when a user starts an intelligent closestool cleaning mode, the MCU matches the corresponding preheating power for an instant heating module according to the deviation between the current alternating current input voltage and 220V, and controls the instant heating module to heat the water to the target temperature; c, the intelligent closestool enters a cleaning mode, and the instant heating module continuously heats to ensure that the outlet water temperature meets the target temperature until cleaning is finished.

Description

technical field [0001] The invention relates to an instant intelligent toilet, in particular to a control method for avoiding over-temperature false alarms of the instant intelligent toilet. Background technique [0002] Since the current smart toilet lid products have been gradually switched from the heat storage type to the instant heating type, the advantage of the instant heating type is that the water temperature is stable and the temperature rises quickly. At the same time, because there is no water tank but the instant heating module is used to heat the running water immediately, so there is no stagnant water and no breeding. Bacteria are more hygienic and healthy. However, for a good user experience, the smart toilet seat requires the outlet water to reach the target temperature within 3 seconds, so it is necessary to use a high-power instant heating module to heat the inlet water, and at the same time, the outlet water temperature should not exceed the set value to ...
