Problems solved by technology

[0005] However, in the above two methods, the reservation mode and other modes cannot be set by the user, and the required heating mode and water consumption cannot be selected and set according to the needs of the user. Therefore, a method that can set the heating mode, Water heater reservation heating method according to water consumption, which is more convenient for users

Embodiment 1

[0033] The water inlet end of the water heater is equipped with a temperature sensor and a flow sensor to detect the inlet water temperature and water intake, and a thermostatic valve and a flow sensor are installed at the mixing place of the water heater outlet pipe and the cold water pipe to control and detect the temperature of the mixed water for bathing and the mixed water for users’ bathing. The water quantity, the temperature sensor, the flow sensor and the thermostatic valve are all electrically connected with the controller inside the water heater. A water regulating valve is arranged between the thermostatic valve and the nozzle to control the water flow switch of the nozzle.

[0034] In this embodiment, a separate thermostatic valve and a flow sensor are installed at the place where the outlet pipe of the water heater and the cold water pipe are mixed to detect the temperature and water intake respectively. In other embodiments, a thermostatic valve with a flow detec...

Embodiment 2

[0080] In this embodiment, on the basis of the first embodiment, the hot water output rate of the water heater is further considered to obtain a more accurate heating temperature of the water heater. The hot water output rate of a water heater is a known value.

[0081] Since the water heater is a closed type, the water output at the outlet end of the water heater is equal to the water intake at the water inlet end, so the water output of the water heater M 热水 .

[0082] However, the hot water heated to the heating temperature cannot be fully output. The hot water coming out of the outlet of the water heater is actually a mixture of hot water heated to the heating temperature and cold water entering from the water inlet of the water heater. The hot water temperature is low. That is to say, the heating temperature of the water heater is inconsistent with the outlet water temperature of the water heater. That is, in Example 1, the calculated T 热水 It is actually the outlet wa...

Embodiment 3

[0091] The difference between this embodiment and Embodiments 1 and 2 is that the user makes an appointment to set the heating start time instead of the heating completion time.

[0092] The reservation heating method of the water heater with mode reservation in the present invention, after the user selects the reservation mode, sets the heating mode, the heating start time, the temperature of the mixed water for the user's bathing, the volume of the mixed water for the user's bathing and the required hot water volume, and the water heater collects Water temperature, the water heater controller calculates the heating temperature, and starts heating when the set heating time arrives, until the required hot water reaches the heating temperature.

[0093] The user sets the temperature of the mixed water for bathing by himself in the appointment mode.

[0094] In the reservation mode, the user sets the required amount of hot water according to the number of bathers and the amount ...

Abstract

The invention relates to a reserving heating method for a water heater with a mode reserving function. A user selects the reserving mode and sets the heating mode, the heating finishing time, the user bathing mixed water temperature, the user bathing mixed water amount and the needed hot water amount. The water heater collects the water inlet temperature, a water heater controller calculates the heating temperature, the water heater starts to perform heating according to the needed hot water amount at a certain moment before the set heating finishing time is up, and the needed hot water is heated to the heating temperature when the set heating finishing time is up. Or the user selects the reserving mode and sets the heating mode, the heating starting time, the user bathing mixed water temperature, the user bathing mixed water amount and the needed hot water amount, the water heater collects the water inlet temperature, the water heater controller calculates the heating temperature, the water heater starts to perform heating when the set heating time is up till the temperature of the needed hot water reaches the heating temperature. In the reservation mode, the user can set the heating finishing time or the heating starting time, and the heating mode, the temperature and the water amount can also be set.

Description

technical field [0001] The invention relates to a reservation heating method for a water heater, in particular to a reservation heating method for a water heater with mode reservation, and belongs to the field of water heater heating methods. Background technique [0002] For the convenience of users and energy saving, the water heater is equipped with a reservation mode in the electric control scheme, that is, to set a time, the heating system of the water heater will start heating at this time, or finish heating at this time. Such as: [0003] 1. The user selects the reservation mode on the controller of the water heater, and inputs the reservation heating time T, such as 18:00, then the water heater will start heating at 18:00, and stop heating when it reaches the set temperature. [0004] 2. The user selects the reservation mode on the controller of the water heater, and inputs the reservation heating time T, such as 18:00, then the water heater will finish heating befo...
