Embodiment 1

[0031] figure 1 It is a flow chart of a method for predicting the remaining bathing time of a water heater provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of predicting the remaining bathing time of a storage-type electric water heater, and the method can be executed by a device for predicting the remaining bathing time of a water heater , the device can be implemented by hardware and / or software, and the method specifically includes:

[0032] S110. Obtain the preset use cut-off temperature and the water temperature in the liner;

[0033] Wherein, the preset use cut-off temperature means that when the water temperature in the inner tank of the water heater is not higher than the preset use cut-off temperature, the hot water in the water heater does not meet the use requirements. The preset use cut-off temperature can be set as a default value when the water heater leaves the factory, or can be set by the user according to his ...

Embodiment 2

[0040] figure 2 It is a flow chart of a method for predicting the remaining bathing time of a water heater provided in Embodiment 2 of the present invention. This embodiment is further refined on the basis of the above technical solution. The method specifically includes:

[0041] S210. Obtain the preset use cut-off temperature and the water temperature in the liner;

[0042] S220. When the water temperature in the inner tank is greater than the preset use cut-off temperature, obtain the water heater's inlet water temperature, outlet water temperature, inner tank volume, outlet water flow rate, and working status of the heating component;

[0043] S230. When the heating component is in the heating state, judge whether the heating power of the heating component exceeds the demand for hot water according to the inlet water temperature, the outlet water temperature and the outlet water flow rate;

[0044]Wherein, if the heating component is in a heating state, the water tempera...

Abstract

The invention discloses a method and device for predicting the remaining bathing time of a water heater, the water heater and a storage medium. The method comprises the following steps that 1, presetuse cut-off temperature and the water temperature in an inner container are obtained; 2, when the water temperature in the inner container is higher than the preset use cut-off temperature, the waterfeeding temperature, the water discharging temperature, the inner container volume, the water discharging flow and the working state of a heating assembly of the water heater are obtained, and the working state of the heating assembly comprises whether the heating assembly is in a heating state or not and heating power; and 3, according to the preset use cut-off temperature, the water temperaturein the inner container, the water feeding temperature, the water discharging temperature, the inner container volume, the water discharging flow and the working state of the heating assembly, the remaining bathing time is determined. According to the technical scheme, under the condition that the number of temperature sensors in the inner container is not increased, the accuracy of predicting theremaining bathing time of the water heater is improved.

Description

technical field [0001] The embodiments of the present invention relate to water heater technology, in particular to a method and device for predicting the remaining bathing time of a water heater, a water heater and a storage medium. Background technique [0002] Water storage type electric water heater is a standing household appliance in life, and the remaining bathing time forecast function of the water heater can provide convenience for users to take a bath. [0003] When estimating the remaining bathing time of the water heater, it is necessary to detect the water temperature in the inner tank of the water heater, and the water temperature in the inner tank will be uneven due to the entry of cold water during the bathing process, which will cause uneven temperature distribution in the tank and affect the accuracy of the calculation results. In order to accurately predict the remaining bathing time, the prior art uses a temperature sensor in the inner tank to detect the ...
