In order to achieve the above technical object, the present invention provides a human body detection method for a washing machine, including an infrared sensor provided on the washing machine, and a control part provided in the washing machine, as shown in fig. 1, the human body detection method including:
11. the operation part acquires the temperature value in the detection range of the washing machine in real time;
12. comparing the obtained temperature value with a preset threshold value, and judging whether a person approaches the washing machine according to a comparison result;
13. and if the fact that a person approaches the washing machine is judged, the current running state of the washing machine is obtained, and the control part controls the backlight of the washing machine according to the running state.
In consideration of integral aesthetic property, when the washing machine is powered off or does not run, the backlight of the operation part is completely extinguished, and meanwhile, control keys with different functions are not separated in the modes of silk screen printing and the like, so that a user cannot know the working state of the washing machine nearby the washing machine.
The above steps 11-13 provide a method for realizing human body detection based on an infrared sensor in a washing machine, which is used for the washing machine with hidden key on the front panel. When the infrared sensor detects that a human body approaches the washing machine, the operating part is electrified, and the indicator lamps in partial areas are lightened, so that the current state of the washing machine can be acquired on the premise that the human body does not contact the operating part; when a human body is far away from the washing machine, the lighted indicator lamp is turned off, the effect of saving electricity is achieved, and in the process, other modes are not needed to be adopted for dividing the functional area, so that the appearance integrity of the washing machine is kept.
The operation unit in this embodiment is an area for switching the operation state of the washing machine, and may be referred to as an operation panel or an operation area, and integrates functions such as a power-on key, program switching, and water volume control, and the control unit is an integrated body disposed inside the washing machine and including components such as a power supply, a main unit circuit board, and a motor, and is configured to execute an operation command of the operation unit.
Optionally, the current operation state of the washing machine includes:
a standby state including shutdown;
and the non-standby state comprises operation, pause and operation end.
In practice, in order to accurately control the backlight of the washing machine so that different lighting effects are exhibited in different states, the operation states of the washing machine are classified.
The operation state is first classified into a standby state where it is not operated, and a non-standby state where it is operated, based on whether the washing machine is operated. Further, the standby state comprises a shutdown state; the non-standby state includes the states of normal washing process, pause triggered by using pause key, and washing end or running end triggered by using stop key.
Based on the listed states, the corresponding backlight adjustment can be performed for each state, so that a user can clearly determine the operation logic of the washing machine according to different types of backlight in different states of the washing machine, and the appearance integrity of the washing machine is maintained on the basis of ensuring the use convenience.

On the contrary, if the washing machine is in the power-off state, it indicates that the washing machine is only powered on and does not perform any washing operation, and only the indicator light of the power-on key on the operation part needs to be lightened to inform the user of the position of the power-on key. When the user uses the power-on key to turn on the washing machine, the indicating lamps of other control areas on the operation panel can be lightened, so that the user can conveniently perform subsequent washing operation. In the power-off state, when a human body moves towards the washing machine, the power-on key indicator lamp of the washing machine is only lightened, so that the consumption of electric energy is reduced on the premise of ensuring the integrity of the operation part of the washing machine.
Optionally, after the indicator light of the power-on key is turned on, the human body detection method further includes:
if the operation of the start-up key is detected within the preset time, the control part controls a backlight circuit positioned below the operation part to be electrified and lights indicator lamps in other areas of the operation part except the start-up key;
wherein the other area includes a regulation area in the operation part and the washing drum.
In an implementation, on the premise of lighting the start key indicator lamp, if the start key is detected to be operated by the user, the control part also lights the indicator lamps in other areas except the start key area on the operation part so that the user can carry out other operations such as washing. Other areas include the washing drum outside the adjusting area for adjusting the water temperature, water level, washing mode, etc. during the washing process.
After the indicator lamp arranged in the washing drum is lighted, a user can observe whether clothes exist in the washing drum or not or whether the clothes in the washing drum are washed cleanly or not on the premise of not opening the washing drum cover. So that the user can observe the condition in the washing drum when the user carries articles in the hand and the cover of the washing drum is inconvenient to open.
Optionally, after the indicator light of the power-on key is turned on, the human body detection method further includes:

In the implementation, contrary to the foregoing, if the operation of the user on the power-on key with the backlight being turned on is not received within the preset time, the control portion controls the backlight circuit to turn off the indicator lamp below the power-on key, so that the operation portion of the washing machine reappears the appearance without the backlight, and the integrity of the appearance of the washing machine is maintained.
It should be noted that the preset time of the embodiment may be set to 3s, and the specific time may be adjusted according to the actual usage environment, so as to prevent the washing machine control part from being in the state of waiting for instructions all the time.
Optionally, if it is determined that a person approaches the washing machine, acquiring a current operation state of the washing machine, and controlling the backlight of the washing machine by the control unit according to the operation state includes:
