Problems solved by technology

[0004] The start time of hot water heating in this traditional reservation method is vague and not very precise, and it is prone to heating too early or too late, which affects the efficiency of the water heater
If the heating time in advance is too early, it will cause unnecessary power consumption; if the heating time in advance is too late, the hot water temperature will not meet the set requirements by the scheduled time, which will affect the user's use of hot water
Therefore, traditional water heaters are difficult to meet the needs of users for energy-saving and comfortable use.

Embodiment Construction

[0034] An embodiment of the water heater reservation heating control method of the present invention, such as figure 1 shown.

[0035] The water heater reservation heating control method provided by the embodiment of the present invention includes the following steps:

[0036] S100: Setting the appointment time t for using hot water 预约 and the preset temperature T 预约 ;

[0037] S200: According to the heating speed ν of the water heater and the preset temperature T 预约 , appointment time t 预约 , the current water temperature T 当前 Calculate the start-up heating time t of the water heater 启动 , t 启动 =t 预约 -(T 预约 -T 当前 )*ν, where, the heating speed ν of the water heater is the time taken for every 1°C rise in the water temperature during the heating process;

[0038] S300: Control the water heater according to the start-up heating time t of the water heater 启动 Turn on the heating.

Abstract

Disclosed is a reserved heating control method for a water heater, comprising: setting a reserved time treservation and a reserved temperature Treservation to use hot water; according to a heating velocity v of the water heater, the reserved time treservation, the reserved temperature Treservation, and a current water temperature Tcurrent, calculating a heating start time tstart of the water heater, tstart = treservation - (Treservation - Tcurrent) * v, wherein the heating velocity v of the water heater is the time required per 1 °C rise in water temperature in the heating process; and controlling the water heater to start heating according to the heating start time tstart of the water heater. Further disclosed is a reserved heating control system for a water heater.

Description

technical field [0001] The invention relates to the technical field of home appliance control, in particular to a water heater reservation heating control method and system. Background technique [0002] With the improvement of people's living standards, people's requirements for the portability and energy saving of household appliances are also getting higher and higher. As a common household appliance, water heaters are constantly being improved with the development of science and technology. [0003] For traditional water heaters with the hot water reservation function, the starting method is relatively simple when hot water in the reservation mode is executed. The reservation method is generally to set the hot water use time in advance, and judge the hot water heating time in advance according to the real-time external environment temperature. The advance time is usually 2h to 4h. [0004] The start-up time of hot water heating in this traditional reservation method is...
