s2: and judging whether the change of the flow of the water channel meets a preset water temperature adjusting condition, and executing corresponding operation of adjusting the water outlet temperature according to the met water temperature adjusting condition when the water temperature adjusting condition is met.
Because the water flow of user at the water consumption point is relevant with the flow in water route that the water heater belongs to, through the water route flow change, can learn the operation of user at the water consumption point to the water valve, the user is at the water consumption point control water valve, so that water route flow changes and satisfies preset temperature regulation condition, and then carry out corresponding regulation leaving water temperature operation according to the temperature regulation condition that satisfies, make the user also can set for the leaving water temperature of water heater at the water consumption point, and in this way, reach the purpose of accurate control water temperature, need not to adjust through mixing the water valve, it is more convenient to make the use, satisfy the user demand.
Referring to fig. 1 to 6, in some embodiments of the present invention, after the step S1, a step S1a is further included: and judging whether the change of the flow rate of the water channel meets a preset set state condition, entering the set state when the set state condition is met, and executing the step S2.
In order to prevent the user from mistakenly triggering the operation of adjusting the outlet water temperature during normal use, a proper setting state condition is set, namely the flow change condition which cannot occur during normal use, such as the flow of a water path fluctuates greatly for multiple times in a short time, so that when the setting state condition is met, the user can be triggered intentionally to adjust the outlet water temperature to enter the setting state and start to detect whether the water quantity change meets the water temperature adjusting condition or not. In this way, the water temperature adjustment can be prevented from being triggered by the user by mistake in the normal use process, and the use is more convenient and reliable.
Referring to fig. 1-6, in some embodiments of the invention, the set state condition is: within the preset time Tset, the waterway flow rate reciprocally varies between the flow rate threshold Qmax and the flow rate threshold Qmin, and the number of reciprocal variations reaches a preset number Nset.
In the preset time Tset, the flow rate of the water path is made to change between the flow rate threshold Qmax and the flow rate threshold Qmin in a reciprocating manner and the reciprocating change reaches the preset number Nset, the flow rate threshold Qmax can be a maximum flow rate value, and the flow rate threshold Qmin can be a minimum flow rate value, namely 0L/min.
The flow threshold Qmax and the flow threshold Qmin can be set according to actual use, the flow threshold Qmax is greater than the flow threshold Qmin, the flow threshold Qmax is generally set to be the maximum value of the water outlet flow of the water heater, and the flow threshold Qmin is 0L/min. The preset number of times Nset may range from 1 to 5 times, preferably 2 times. Since the time range of the normal water valve opening and closing by the user is 0.2s-3s, the range of the preset time Tset may be Nset 0.2s-Nset 3s, preferably Nset 1.5s, according to the preset number of times Nset.
Referring to fig. 1 to 6, in some embodiments of the invention, after step S1a, step S2a is further included: after entering the set state, the timer starts counting, and after the preset time Tout elapses, the set state is exited, and the process returns to step S1.

s22: and judging whether the change of the flow of the water channel meets a preset water temperature rising condition, and if so, adjusting the rising temperature of the outlet water to be a preset temperature value delta T2.
When the water path flow meets the water temperature reduction condition, the water heater adjusts the water outlet temperature to reduce the preset temperature value delta T1, correspondingly, when the water path flow meets the water temperature increase condition, the water heater adjusts the water outlet temperature to increase the preset temperature value delta T2, and therefore a user can conveniently and accurately adjust the water outlet temperature of the water heater. The predetermined temperature Δ T1 and the predetermined temperature Δ T2 may be equal or different. The predetermined range of Δ T1 may be 1 deg.C to 5 deg.C, preferably 1 deg.C, and the predetermined range of Δ T2 may be 1 deg.C to 5 deg.C, preferably 2 deg.C.

Correspondingly, when the water temperature is too low, a user can enable the flow rate of the water channel to continuously rise by slowly opening the water valve, timing is started when the flow rate of the water channel rises from the flow threshold value Qmin until the flow rate of the water channel stops rising, and the timing is stopped, and if the timed time Tup is greater than the preset time T2, the water heater rises to the preset temperature value delta T2.
In this way, the water temperature of the water heater can be adjusted by controlling the opening or closing speed of the water valve at a water using point by a user, and the water temperature adjusting device is simple to operate and easy to realize.
