Description
Technical Field
The invention relates to the field of household appliances, in particular to a control method of a hot water system.
Background
Because the gas heater is installed in the kitchen, and is far away from bathroom shower faucet, can have a large amount of water in the water pipe of connection, people need put long section cold water when the bathing, and user experience is poor still forms extravagantly. For cold water stored in a pipeline, a plurality of zero-cold-water solutions are available at present, and the temperature of cold water in a circulating heating pipe is generally 30-40 ℃. The problem of cold water in the pipeline is solved, but the water temperature in the pipeline is easier to breed bacteria, and people can have bad influence on the health of people by washing water, bathing water, kitchen water and the like.
At present, the existing sterilization scheme of the water heater adopts high-temperature sterilization, the water temperature of the water heater is heated to more than 60 degrees, the high-temperature sterilization is carried out, the sterilization is not thorough in the sterilization mode, the sterilization efficiency of more than 90 percent cannot be achieved, and the gas water heater discharges water at constant temperature, so that the water temperature is too high, and a user cannot use the gas water heater. The temperature of outlet water of a gas water heater is generally set to be about 40 degrees, and is an appropriate temperature for breeding a large amount of bacteria. And the water in the pipeline is not sterilized;
at present, most of zero cold water is circularly heated in a plurality of modes, 1, the problem that water in a water pipe is only sensed is solved, and when the water temperature is lower than a certain temperature, a water pump starts circulating water and then heats the water. 2. A user actively operates the display panel keys, and one key is used for heating in a single cycle; 3. a user heats water in the circulating water pipe in a time reservation mode; above scheme all can cause the frequent start-up of water pump, and the temperature is low just starts the circulating pump heating, causes unnecessary waste, and in-process user experience feels not good moreover.
The existing zero-cold-water gas water heater adopts cold water in a heating pipe of a circulating pump, generally, after the temperature of the water in the pipe is sensed to be lower than a starting temperature, a water pump is started immediately to carry out circulating heating, and whether a user really uses water to bathe cannot be determined. In addition, the sterilization scheme adopts high-temperature sterilization, the water temperature of the water heater is heated to more than 60 degrees, the high-temperature sterilization is carried out, the sterilization is not thorough, the sterilization efficiency of more than 90 percent cannot be achieved, the water temperature of the water discharged from the gas water heater is generally set to about 40 degrees, and the water temperature is the proper temperature for breeding a large amount of bacteria. Because the gas water heater is installed in a kitchen and is far away from a shower faucet of a toilet, a large amount of water can be stored in a connected water pipe, and the water in the pipe is not sterilized, although a plurality of zero-cold-water solutions are already available at present, the temperature of cold water in a circulating heating pipe is generally 30-40 degrees. However, bacteria are easy to breed at the water temperature in the pipeline, and at present, a scheme for completely sterilizing the water discharged from the water heater and the water stored in the pipeline is not well solved.
The present invention has been made in view of this situation.
