Example one
The embodiment provides a control method of a washing machine, the washing machine is provided with a steam generating device, comprising a steam washing program, and the control method comprises the following steps:
when the washing machine executes a steam washing program, steam is introduced into the inner barrel for a certain time, and then a centrifugal washing process is started to be executed.
Silver ion disinfectants used in the current market need to be replaced or added after being used for a period of time. In the scheme, the steam washing program is arranged on the washing machine, so that the washing machine is started when a user needs to sterilize the clothes, the steam washing program is selected to sterilize the clothes by steam, other operations are not needed, and the steam washing machine is convenient and simple to use.
In the scheme, the washing machine can be a drum washing machine, a pulsator washing machine, a double-barrel washing machine and the like. The steam generating device comprises a heating device, water is fed into the heating device, and the heating device generates steam after starting to work. The arrangement mode and the installation mode of the steam generating device can adopt the scheme in the prior art, and also can be an improved scheme, and the steam can be generated and input into the inner barrel, and the steam can be introduced between the inner barrel and the outer barrel, and also can be directly introduced into the inner barrel.
In the scheme, after a user selects a steam washing program, the washing machine firstly introduces steam into the inner barrel for a certain time, so that the temperature of the inner barrel can reach the sterilization and mite removal degree in the period of time, and the aim of killing all mites and bacteria is fulfilled. In the scheme, the temperature, the flow rate, the time and the like of the steam can be preset, and the washing machine controls the steam generating device to generate the steam with certain temperature and controls the flow rate and the time of the steam entering the inner barrel according to the preset value, so that the inner barrel can reach the required temperature in a short time. For example, the temperature of the water vapor may be set in the range of 50-100 ℃.
The scheme is that after steam is introduced into the inner barrel for a certain time, a centrifugal washing process is started to be executed, and the centrifugal washing process is that the inner barrel is controlled by the washing machine to rotate at a certain rotating speed. In the centrifugal washing process, clothes in the inner barrel can be distributed on the inner wall of the inner barrel under the action of centrifugal force and are attached to the inner wall or can climb upwards along the inner wall. For the condition that the clothing is piled up in interior bucket bottom, in the centrifugal washing process, the area of contact with steam can greatly increased when the clothing distributes along the inner wall of interior bucket to can both play the effect of killing bacteria and removing the mite to all clothing, each position of each clothing, improve the rate of disinfecting.
In a further scheme, when the centrifugal washing process is executed, the washing machine controls the inner drum to rotate forwards and/or backwards at a certain speed so as to change the contact area of the clothes and the steam.

In the scheme, in the time T, the temperature of the inner barrel does not reach the preset value N due to the introduced steam, the influence of factors such as low ambient temperature is shown, and the efficiency of sterilizing by adopting the steam at the temperature is lower. The control device of the washing machine controls the steam generating device to improve the temperature of the generated steam, so that the time is shortened, the sterilization effect and efficiency are ensured, and different scenes and environments can be better adapted.
Preferably, the washing machine monitors the temperature in the inner tub in real time after controlling the temperature of the steam generated from the steam generating device from a to b, and starts to perform a centrifugal washing process when the temperature reaches a preset value N.
In a further scheme, after steam is introduced into the inner barrel for a certain time T, if the temperature in the inner barrel is greater than a preset value N and exceeds a certain value, the temperature of the steam generated by the steam generating device is controlled by the washing machine to be reduced from a to c, wherein c is less than a.
Under the condition, the temperature of the introduced steam is too high, and the adverse effect on the parts of the washing machine can be generated, so that the control device of the washing machine can adjust the temperature of the steam generated by the steam generating device in time, the sterilization rate is ensured, and the running safety of the washing machine can be protected.
In the scheme, the washing machine controls the temperature of the steam generated by the steam generating device according to whether the temperature of the inner barrel reaches the preset value N within a certain time, so that the washing machine is more suitable for different environments and scenes, such as winter and summer, cold regions, hot regions and the like, and has wider applicability.
