[0002] Various central gas water heaters currently on the market have realized the instant heating function of gas water heaters to a certain extent, but every time when users want to use hot water immediately, the current central gas water heaters always have to wait for a few days. Minutes of heating time and a period of water pump circulation, etc., did not achieve "real inst...

[0044] figure 1 This is a schematic diagram of the structure of the water heater 100 provided by the first embodiment of the present invention, please refer to figure 1 . The dotted line in the figure represents the cold water pipe 133, the solid line represents the hot water pipe 131, and the arrow represents the direction of water flow in the water flow pipe.
[0045] The water heater 100 provided in this embodiment includes a heater 110, a water pump 120, a water flow pipeline, a one-way valve 140, a first temperature sensor 151, a second temperature sensor 153, a timer, a temperature limiter, a flow meter, and a control 器160.
[0046] The heater 110 includes a water inlet 111 and a water outlet 113. The water pump 120 is connected to the water inlet 111. The one-way valve 140 is arranged on the water flow pipe. The first temperature sensor 151 is arranged on the water inlet 111 to detect the temperature of the inlet water. . The second temperature sensor 153 is provided at the...

[0060] figure 2 This is the control principle diagram of the water heater preheating method provided by the second embodiment of the present invention, please refer to figure 2 .
[0061] The preheating method for a water heater provided in this embodiment is applied to the water heater 100 in the first embodiment and includes the following steps:
[0062] S1: Automatically judge the tube length. The length of the water flow pipeline of the water heater 100 is judged, and the preheating period T of the entire pipeline is determined.
[0063] S2: Determine the operating time λT of the water pump 120 in the warm-up phase. That is, the preheating period λT of the hot water pipe 131 is determined and the preheating period λT of the hot water pipe 131 is stored.
[0064] S3: Warm up ahead of time λT. When the system time of the water heater 100 is in the reserved time period set by the user and is advanced by λT, and the water temperature in the hot water pipe 131 is lower than the pre...

Abstract
The invention provides a water heater preheating method and a water heater and relates to the technical field of water heaters. The water heater preheating method comprises the steps that the length of a water flow pipeline is judged at first, running of a water pump runs and heating of a heater as well as a full-pipeline preheating cycle T allowing the water temperature of the whole water flow pipeline to reach the preset water temperature are determined, then a half-pipeline preheating cycle delta T for heating water in a hot water pipeline to the preset water temperature is determined, after a user starts the preheating function, the water heater starts preheating delta T earlier than the appointment time interval of the user so that the water temperature in the hot water pipeline can meet the preset water temperature when the user uses the water, water is hot instantly when needed, and user experience is improved. According to the water heater provided by the invention, the preheating method is adopted, the water flow pipeline is provided with a one-way valve, the hot water pipeline and a cold water pipeline are separated, and only water in the hot water pipeline is heated whenthe water heater carries out preheating, so that the heating time is shortened, energy consumption is reduced, and user experience is great.
Description
Technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater preheating method and a water heater. Background technique [0002] The various central gas water heaters currently on the market have realized the instant heating function of gas water heaters to a certain extent, but every time the user wants to use hot water immediately, the current central gas water heaters always have to wait a few minutes. Minutes of heating time and a period of time after the water pump recirculates, etc., but did not achieve "real sense of instant heating", zero wait for water, and poor user experience. [0003] In addition, most gas water heaters on the market have the function of pre-heating to a certain extent, but while realizing that there is no return water pipe that can be heated immediately, it needs to heat the cold water pipe water every time, which wastes part of the energy. Did not make full use of energy. [0004] In view of thi...
