EXAMPLE five
The embodiment provides a control method of a washing machine, comprising the following steps: in the process of executing a washing program by the washing machine, the laundry treating agent feeding mechanism controls the feeding nozzle 43 to feed the laundry treating agent into the washing chamber of the washing machine; when the washing machine does not execute the washing program and receives a laundry treating agent feeding instruction, the laundry treating agent feeding mechanism controls the feeding nozzle 43 to spray the laundry treating agent.
The laundry treating agent feeding mechanism of the washing machine of the embodiment can feed the laundry treating agent into the washing machine during washing, and can also spray the laundry treating agent for special use of a user when the washing machine is not used for washing, such as manual rubbing and washing of the laundry.
Specifically, a control panel 7/display screen of the washing machine is provided with a foam reagent option and a washing liquid option, when a user selects a washing program, the foam reagent option or the washing liquid option can be simultaneously selected, and when the washing machine closes a machine door 9 to execute the washing program, the liquid clothes treating agent or the foam clothes treating agent is controlled to be put in according to the selection of the user. The washing machine can default to 'foam reagent' or 'washing liquid', and when a user does not select the detergent, the washing machine puts in the detergent according to default information.
Further, when the door 9 of the washing machine is opened, the sensing device 5 senses the clothes information to control the clothes treating agent feeding mechanism to feed the foamy clothes treating agent, and when the door 9 is closed, the feeding operation is not executed even if the clothes information is sensed, so that the phenomenon that after the door 9 is closed, the motion of clothes in the washing machine interferes with a sensing signal of the sensing device to influence the clothes treating agent feeding mechanism is avoided.
When the door 9 is opened, a set value of the distance between the clothes and the sensing device 5 or the clothes input opening is set for preventing misjudgment, and when the sensing device 5 judges that the distance between the clothes and the clothes is less than the set value, the clothes treating agent input mechanism starts to input the foamy clothes treating agent, so that the misoperation is prevented.
It is to be noted that the laundry treating agent defined by the present invention includes: at least one of a detergent, a softener, a disinfectant, a bleaching agent and a flavoring agent.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
