Example one
Fig. 1 shows an implementation flowchart of a zero-cold water bathing control method provided by a first embodiment of the present invention, which includes the following steps:
in step S101, bathing water data of a user is collected, where the bathing water data includes a starting water usage time of the user, and a first inlet water temperature, a first target water temperature, and a first cycle preheating time of circulating water.
In the embodiment of the invention, bathing water data of a user can be acquired through an acquisition device, wherein the acquisition device comprises but is not limited to a temperature sensor and a timer; the temperature sensor is used for collecting a first inlet water temperature and a first target water temperature of circulating water, and the timer is used for collecting first circulation preheating time of a user, water using starting time of the user and the like.
In the embodiment of the invention, the first inlet water temperature is the temperature of the circulating water of the water heater entering the water heater.
As an embodiment of the present invention, the first target water temperature may also be obtained by a user setting a temperature button on a control board of the water heater.
In the embodiment of the invention, the first inlet water temperature can be 1 ℃, 2 ℃, 5 ℃, 10 ℃, 20 ℃ and the like, and is determined according to the actually collected inlet water temperature of the circulating water.
In the embodiment of the present invention, the first target water temperature is 35 ℃, 36 ℃, 38 ℃, 40 ℃, 45 ℃, 50 ℃ or the like, and it can be understood that the first target water temperature is greater than the first inlet water temperature.
In the embodiment of the invention, the first cycle preheating time is the time for heating the circulating water in the water heater from the first inlet water temperature to the first target water temperature.
In one embodiment of the present invention, the first cycle preheating time may be 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, etc., and is not particularly limited.

It can be understood that the circulating preheating parameters are different according to the length of the pipeline through which circulating water flows, the heat preservation performance of the pipeline and the like.
For example, if the first inlet water temperature is 15 ℃, the first target water temperature is 40 ℃, and the first cycle preheating time is 5 minutes, the cycle preheating parameter may be determined to be 5.
For example, if the first inlet water temperature is 10 ℃, the first target water temperature is 40 ℃, and the first cycle preheating time is 6 minutes, the cycle preheating parameter may be determined to be 5.

The calculation formula is as follows: the first target water temperature is T1The first inlet water temperature is T2Then the first temperature difference Δ T1，ΔT1＝T1-T2。
In an embodiment of the present invention, the cyclic preheat parameter may be calculated as follows: first cycle preheating time t1First temperature difference Δ T1The cyclic preheating parameter is k, k is t1/ΔT1。
For example, if the first target water temperature is 36 ℃, the first inlet water temperature is 6 ℃, and the first cycle preheating time is 3 minutes, the first temperature difference Δ T may be calculated first1At 30 ℃, the cyclic preheat parameter k was calculated to be 1/10. According to the embodiment of the invention, the cycle preheating parameters of the water heater can be accurately calculated through the acquired first inlet water temperature, the acquired first target water temperature and the acquired first cycle preheating time, so that the accuracy of determining the second cycle preheating time is improved.

In the embodiment of the invention, the second-cycle preheating time t2Multiplying the cyclic preheat parameter k by Δ T2I.e. t2＝k×ΔT2。
For example, in the example of FIG. 2 above, the water heater testWhen the second inlet water temperature was measured to change to 3 c and the second target water temperature was measured to change to 43 c, the second temperature difference Δ T was first calculated in this example according to the cycle preheating parameter calculated in the example of fig. 2 above as 1/102The second cycle preheating time t can be calculated again when the temperature is 43-3 ℃ and 40 DEG C21/10 × 40 deg.C for 4 minutes.
According to the zero-cold-water bathing control method provided by the embodiment of the invention, the second cycle preheating time can be accurately calculated through the second target water temperature, the second inlet water temperature and the calculated cycle preheating parameter, so that when the inlet water temperature or the target water temperature changes, the accurate second cycle preheating time is determined in real time, the heating starting time is automatically adjusted, zero-cold-water bathing is realized, and the user experience is better.
