Further, under the condition that Δ1 is less than or equal to A1 and Δ2 is less than or equal to A2, the difference between the water temperature of the water to be discharged and the target water temperature is smaller, and the difference between the water flow rate and the target flow rate is smaller, so that the water outlet end of the heating chamber is directly communicated with the water outlet component, and the influence on normal water taking of a user can be avoided.

Further, in the case where Δ1 > A1 and/or Δ2 > A2, it is explained that one of the difference between the outlet water temperature and the target water temperature and the difference between the outlet water flow rate and the target flow rate is large or the difference between the outlet water temperature and the target water temperature and the difference between the outlet water flow rate and the target flow rate are large, at this time, the outlet end of the heating chamber is communicated with the water tank, so that it is possible to avoid excessively large difference between the outlet data of the water flowing out from the outlet member and the target data.

Further, under the condition that the water outlet end of the heating chamber is communicated with the water tank, the difference between the water outlet data and the target data is larger, at this time, the water outlet temperature reaches the target water temperature by adjusting the heating member, and/or the water outlet flow of the water outlet end of the heating chamber reaches the target flow by adjusting the water pump, so that the water outlet temperature and the water outlet flow can be timely adjusted, the water outlet temperature of the water which flows out of the water outlet member after adjustment is closer to the target water temperature, the water outlet flow of the water which flows out of the water outlet member is closer to the target flow, and the use experience of a user is further improved.

Further, in the case of Δ1 > A1 and Δ2 > A2, it is explained that the difference between the water temperature of the water outlet end of the heating chamber and the target water temperature and the difference between the water outlet flow rate and the target flow rate are both large, at this time, the difference between the water outlet temperature and the target water temperature is reduced by adjusting the heating member, the difference between the water outlet flow rate and the target flow rate is reduced by adjusting the water pump, so that the water outlet temperature of the water flowing out from the water outlet member reaches the target water temperature, the water outlet flow rate reaches the target flow rate, and the difference between the water outlet data and the target data is reduced.

Further, under the conditions that Δ1 is larger than A1 and Δ2 is smaller than or equal to A2, the difference between the water outlet temperature of the water outlet end of the heating chamber and the target water temperature is larger, the difference between the water outlet flow and the target flow is smaller, at the moment, the water outlet temperature of water flowing out of the water outlet member can reach the target water temperature only by adjusting the heating member to reduce the difference between the water outlet temperature and the target water temperature, the adjusting frequency of the water pump can be reduced without adjusting the water pump, the adjusting time is saved, the waiting time of a user can be reduced, and the use experience of the user is further improved.

Further, in the case where Δ1 is less than or equal to A1 and Δ2 is greater than A2, it is explained that the difference between the water temperature at the water outlet end of the heating chamber and the target water temperature is small, and the difference between the water outlet flow rate and the target flow rate is large, by adjusting the water pump to reduce the difference between the water outlet flow rate and the target flow rate, so that the water outlet flow rate of the water flowing out from the water outlet member reaches the target flow rate, since the water outlet flow rate of the water outlet end of the heating chamber changes after adjusting the water pump, the change in the water outlet flow rate is likely to affect the water outlet temperature, by further acquiring the current water temperature at the water outlet end of the heating chamber after adjusting the water pump, and selectively adjusting the heating member according to the current water temperature and the target water temperature, when the difference between the current water temperature and the target water temperature is small, by not adjusting the heating member, the adjusting frequency of the heating member can be reduced, and the waiting time of a user can be reduced; when the difference between the current water temperature and the target water temperature is large, by adjusting the heating member in time, it is possible to avoid an excessive difference between the water temperature of the water discharged from the water discharging member and the target water temperature after adjusting the water pump.

By such a setting, when Δ3+.A3, it is indicated that the difference between the current water temperature at the water outlet end 32 of the heating chamber and the target water temperature is relatively small after adjusting the water pump 2, that is, that the water temperature at the water outlet end 32 of the heating chamber is not changed too much by adjusting the water pump 2, at this time, the adjusting frequency of the heating member 3 can be reduced by not adjusting the heating member 3, and at the same time, the waiting time of the user is reduced, and the use experience of the user is further improved.

Illustratively, if Δ1+.A1 and T+.t0, Δ2 > A2 and Q < Q0, then the water pump 2 is first adjusted to increase the water flow out of the water outlet end 32 of the heating chamber, without adjusting the heating member, the water temperature out of the water outlet end 32 of the heating chamber will necessarily decrease, if the water temperature out of the water outlet at this time is reduced but still satisfies Δ1+.A1, then the heating member 3 is not adjusted.

With such a setting, when Δ3 > A3, it is explained that the difference between the current water temperature and the target water temperature is relatively large, and by adjusting the heating member 3 in time to reduce the difference between the current water temperature and the target water temperature, it is possible to make the outlet water temperature of the water flowing out from the outlet water member 5 close to the target water temperature, avoiding the excessively large difference between the outlet water temperature and the target water temperature due to the adjustment of the water pump 2.

It should be noted that, in practical application, the heating power of the heating member 3 may be adjusted to make the water temperature of the water reach the target water temperature, or the input voltage of the heating member 3 may be adjusted to make the water temperature of the water reach the target water temperature, etc., and such adjustment and change of specific adjustment parameters of the heating member 3 should be included in the protection scope of the present invention without departing from the principle and scope of the present invention.

Specifically, in the case of Δ1 > A1, the control method of the present invention further includes the steps of:

judging whether the water temperature of the water is larger than the target water temperature;

according to the judgment result, the heating power of the heating member 3 is adjusted.

Through such setting, under the condition that Δ1 > A1, namely, the difference between the water temperature of the effluent and the target water temperature is larger, the heating power of the heating member 3 can be accurately adjusted by judging the sizes of the water temperature of the effluent and the target water temperature at this time, so that the water temperature of the effluent can be quickly adjusted to the target water temperature, and the use experience of a user is further improved.

if the judgment result is yes, the heating power of the heating member 3 is reduced;

if the determination result is "no", the heating power of the heating member 3 is increased.

With such a setting, in the case where the determination result is yes, it is explained that the water temperature of the water discharged at this time is greater than the target water temperature, that is, the water temperature of the water discharged is high, and the water temperature of the water discharged can be reduced by decreasing the heating power of the heating member 3, so that the water temperature of the water discharged can be quickly adjusted to the target water temperature; in the case where the determination result is "no", it is indicated that the water temperature of the water discharged at this time is smaller than the target water temperature, that is, the water temperature of the water discharged is low, and the water temperature of the water discharged can be raised by increasing the heating power of the heating member 3, so that the water temperature of the water discharged can be quickly adjusted to the target water temperature.

It should be noted that, in practical application, the power of the water pump 2 may be adjusted to enable the water flow to reach the target flow, or the input voltage of the water pump 2 may be adjusted to enable the water flow to reach the target flow, or the rotational speed of the water pump 2 may be adjusted to enable the water flow to reach the target flow, etc., and such adjustment and change of specific adjustment parameters of the water pump 2 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.
