The second embodiment:
the present embodiment is a further improvement on the first embodiment, and as shown in fig. 2, includes the following steps:
and S21, heating the washing machine after the washing machine enters water to a preset water level.
In the embodiment, the water inlet valve can be an electromagnetic valve, and the control device of the washing machine controls the opening and closing of the electromagnetic valve.
Before opening the water inlet valve, a preset water level needs to be set, and the preset water level can be a common washing water level set by the washing machine or a water inlet water level set according to the requirement of a user.
And after water enters, detecting the actual water inlet level, and closing the water inlet valve to stop water inlet when the water inlet level is the same as the preset water level.
In this embodiment, the water inlet level can be determined by the water inlet time, that is, the preset water inlet time is determined by the preset water level and the measured water inlet flow, and when the water inlet time reaches the preset water inlet time, the water inlet valve is closed and the water inlet is stopped. The specific principle is as follows: the water inlet pipeline is provided with a water inlet valve which is an electromagnetic valve, the flow of inlet water is measured by measuring devices such as a flowmeter, and if the electromagnetic valve is opened for a certain time t and the water with a certain volume can reach the preset water level, the t can be used as the preset parameter of inlet water, namely the preset inlet time. And then in the actual use process, when the water inlet time reaches the preset water inlet time, the water inlet valve can be closed, and the water inlet is stopped.
In other embodiments, the inlet water level may also be determined by the total inlet water flow, that is, the preset total inlet water flow is determined by the preset water level, and when the total inlet water flow reaches the preset total inlet water flow, the inlet valve is closed, and the inlet water is stopped. And calculating the preset total inflow flow through the preset water level, then arranging a liquid flowmeter at the water inlet valve, and measuring the total inflow flow through the liquid flowmeter. The liquid flowmeter is an instrument for measuring and calculating the water flow of a measured water inlet electromagnetic valve and the total water inlet flow in a certain time interval. The liquid flowmeter can be divided into instantaneous flow and accumulated flow (namely total inflow), wherein the instantaneous flow is the amount of water passing through the effective section of the water inlet pipe in unit time; the cumulative flow is the cumulative amount of flow through the effective cross-section of the inlet pipe over a time interval. The total intake water amount can be obtained by the accumulated flow, or the accumulated flow (total intake water flow) can be obtained by integrating the instantaneous flow with time, and then the total intake water flow is compared with the calculated preset total intake water flow.
And when the inlet water reaches the preset water level, a heating device of the washing machine is started to heat the water.
And S22, when the water temperature reaches the preset temperature, continuing to heat and detecting the water temperature, and comparing the detected temperature with the last detected temperature.
The washing machine detects the temperature of water through the temperature sensor, and when the detected temperature is equal to a preset temperature, the temperature of the water is continuously detected, and the detected temperature is compared with the temperature detected last time.
The preset temperature is T1, and the value range of the preset temperature T1 is more than or equal to 80 ℃ and less than T1 and less than 100 ℃. Due to the fact that the boiling points of different regions are different, the preset temperature is set to be more than or equal to 80 ℃ and less than T1 and less than 100 ℃, and the boiling points of the different regions can be conveniently obtained. The preset temperature may be set to 80 deg.c, 85 deg.c, 90 deg.c, 95 deg.c, etc. In this embodiment, the preset temperature T1 is set to 80 ℃ lower than the boiling point in most areas, so that the actual boiling point temperatures in different areas can be conveniently detected. The preset temperature T1 can also be other temperatures within the temperature range of between 80 and T1 and less than 100 ℃.
S23, determining whether the detected temperature is equal to the last detected temperature.
If yes, go to step S241; if not, the process proceeds to step S242.
And S241, storing the detected temperature.
And S242, detecting the temperature of the water once every first preset time period.
In another embodiment, the temperature of the water may be detected every second preset time period within a first preset time period, the detected temperature may be compared with the temperature detected last time, and if the detected temperatures within the first preset time period are all equal, the detected temperatures may be stored.
And S25, judging whether the number of the storage temperatures is equal to the preset number.
If yes, go to step S261; if not, the process goes through step S262 and returns to step S21.
Whether the number of the storage temperatures is equal to the preset number or not is judged, a plurality of temperatures can be automatically and repeatedly acquired, and accidental situations are prevented. The number of times of repeatedly detecting the temperature is set according to the requirement, and a selection key can be arranged on the washing machine, and the cycle number is set through the selection of a user.
And S261, obtaining an average value of the plurality of storage temperatures to obtain a boiling point temperature, and storing the boiling point temperature as a target temperature for heating the washing machine.
The method comprises the steps of obtaining a plurality of storage temperatures, averaging the obtained storage temperatures, wherein the obtained average value is the boiling point temperature, so that the local boiling point temperature can be obtained more accurately, and accidental situations are prevented. And storing the boiling point temperature as the target heating temperature of the washing machine, and calling the boiling point temperature as the target heating temperature when the washing machine performs a heating program or hot washing.
Washing machines typically include a heating program in a washing program and/or a rinsing program. At present, the heating program of the pulsator washing machine is in a washing stage and a rinsing stage, the heating program of the drum washing machine is mostly in the washing stage, and the washing machine is heated after water inflow is finished, so that the effect of high-temperature sterilization and disinfection is achieved. The heating target temperature is called in the heating program, so that the clothes can be sterilized and disinfected, a better washing effect is obtained, and the condition that the washing machine is heated all the time and is dried can be avoided.
And S262, draining water in the washing machine.
By returning to step S21 after draining the water in the washing machine, a plurality of storage temperatures can be obtained. The discharged water is clean and can be utilized, so that the waste of water resources is avoided; the water can be reheated after being cooled, so that the waste of resources is prevented, for example: by circulating the water, the water is cooled in the circulation process.
