Control method for pre-operation of water heater

Abstract

The invention relates to a control method for pre-operation of a water heater. The method comprises the following steps that one day is divided into a plurality of time intervals, and a hot water use frequency of the water heater in each time interval is recorded; a plurality of target operation intervals are obtained according to the treatment of the hot water use frequency in each time interval; the water heater is controlled to operate in advance before the time of each target operation interval reaches. Compared with the prior art, the control method disclosed by the invention has the advantages that the water heater is subjected to pre-operation control according to a hot water use habit of a user, so that the operation of manually starting the water heater by the user in a timing manner is unnecessary, and the heating timeliness of the water heater is improved, therefore the water heater is more intellectualized and humanized, the demand for a large amount of water of the user is also met at the same time, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of water heater control, in particular to a water heater pre-operation control method. Background technique [0002] The function of the water heater is to increase the temperature of cold water into hot water within a certain period of time for users to use. With the development of water heater technology, the level of intelligent control technology of water heaters has also been improved to a certain extent. For example, the control unit of existing water heaters is automatically operated by microcomputer control, which can be set according to the user's heating timing and the water temperature stored in the water tank. The temperature difference between the environment and the water temperature set by the user can be automatically started and stopped without special personnel on duty. That is to say, in the prior art, the control of starting and stopping the water heater is realized by comparing the temp...

Problems solved by technology

That is to say, in the prior art, the control of starting and stopping the water heater is realized by comparing the temperature difference between the water temperature set by the user and the water temperature stored in the water tank, so it can be known that the existing water heater has the following defects: (1) the user needs to manually Only when the water heater is turned on in advance at regular intervals can the water heater heat the water, which cannot meet the current needs of the user, is low in timeliness, is not intelligent and humanized, and has a certain impact on the user experience; (2) when the heat in the water tank When the water is used in large quantities and keeps flowing out, the water heater needs to continue to reheat the water entering the water tank for a certain period of time, which cannot meet the customer's demand for a large amount of water at a certain moment; (3) If the user leaves home for a long time and does not turn off the water heater, the water heater will still Automatically turn on according to the temperature difference between the water temperature set by the user and the water temperature stored in the water tank, resulting in waste of electricity, which is not conducive to energy saving and carbon reduction
