As shown in fig. 1, an embodiment of the present invention provides a control device for an intelligent home appliance, where the control device may include: an infrared sensor 101, an infrared projection device 102, and a control module 103; wherein,,
the infrared sensor 101 is arranged on the intelligent household appliance body;
the infrared sensor 101 is configured to send trigger information to the control module 103 when detecting that human body induction information exists in the first designated area;
the control module 103 is configured to trigger the infrared projection device 102 when receiving the trigger information sent by the infrared sensor; when detecting that a user triggers a target function key in at least one function key in a second designated area, determining a target working state corresponding to the target function key, and controlling the intelligent household appliance body to operate in the target working state;
the infrared projection device 102 is configured to project the at least one function key in the second designated area when triggered.
In the above embodiment, by setting the infrared sensor on the intelligent home appliance body, when the user enters the first designated area corresponding to the infrared sensor, the infrared sensor can detect the human body sensing information in the first designated area, and at this time, the infrared sensor sends the triggering information to the control module. The control module can trigger the infrared projection device according to the trigger information, so that the infrared projection device projects at least one function key in the second designated area, and when a user triggers a target function key in the plurality of function keys projected in the second designated area according to actual requirements, the control module determines a target working state corresponding to the target function key and controls the intelligent household appliance body to operate in the target working state. Because the infrared projection device generally projects in a relatively open area such as the ground, the corresponding area of each projected functional key is relatively large, a user can trigger a target functional key by using feet or other body parts, and the working state of the intelligent household appliance can be regulated when the hands are inconvenient, so that the user experience is improved.
In one embodiment of the present invention, the at least one function key includes: a door opening key;
the control module is used for determining that the target working state is a door opening state when the door opening key is triggered by a user; and determining the current state of the door body of the intelligent household appliance body, and driving the door body of the intelligent household appliance body to be opened when the current state of the door body is a door closing state.

Corresponding text information can be displayed on each projected function key to prompt the corresponding function.
For intelligent household appliances with door bodies, such as refrigerators and disinfection cabinets, automatic door opening and closing is realized, so that hands of users are liberated, and user experience is improved. Therefore, for the intelligent household appliance with the door body, the door opening key is included in the plurality of function keys projected by the infrared projection device. Taking a refrigerator as an example, when an infrared sensor arranged at the top of the refrigerator detects that a person approaches the refrigerator, the control module can trigger the infrared projection device, the infrared projection device is generally arranged on a bottom cross beam of the refrigerator, and when the infrared projection device is triggered, a function key can be projected on the ground in front of a refrigerator door body, and a user can trigger the projected door opening key by feet. When the control module detects that a user triggers a door opening button, whether the refrigerator door body is in a door closing state currently is detected, and if so, the refrigerator door body is driven to be opened.
It can be understood that when a user wants to adjust the door body of the refrigerator from the door opening state to the door closing state after storing or taking out the articles in the refrigerator, the door closing button projected by the infrared projection device can be triggered. When the control module detects that a user triggers a door closing button, whether the current state of the refrigerator door body is in a door opening state or not is detected, and if so, the refrigerator door body is driven to be closed. Therefore, when the hands of a user are inconvenient, the switch state of the intelligent household electric door body can be conveniently adjusted, the intelligent household electric door body can be automatically opened and closed, the operation flow of opening and closing the door of the intelligent household electric appliance is simplified, the technological sense and the intelligent level of the intelligent household electric appliance are improved, and the user experience is improved.

In one embodiment of the invention, when the control module drives the door body of the intelligent household appliance body to open, the door opening device arranged on the intelligent household appliance body is mainly driven to operate, wherein the door opening device can be a jacking device, and the jacking device is arranged at the bottom or the top of the intelligent household appliance body. When the control module determines that the current state of the door body is a door closing state, the motor in the jacking device is driven to rotate, so that the motor drives the push rod in the jacking device to move according to a set stroke in the rotating process, and the door body of the intelligent household appliance is jacked in the moving process of the push rod.
In addition, the door opening device can also be a rotating motor, the rotating click is fixedly arranged at the hinge position of the door body, when the control module determines that the current state of the door body is a door closing state, the rotating motor is driven to rotate, so that the rotating motor drives the hinge of the door body to move in the rotating process, and the door body is driven to be opened. From this, control module runs through drive top open device or rotating electrical machines, realizes the door body automatic switch of drive intelligent household electrical appliances body, improves user experience.
In one embodiment of the present invention, the control module 103 is configured to start timing when detecting that the door opening key is triggered by a user; and determining whether the door opening key is continuously triggered within a preset standard time period, and if so, driving the door body to open when the recorded time period reaches the preset standard time period.
When the control module detects that a user triggers the door opening key, the timer is utilized to start timing, and if the duration recorded by the timer reaches t and the door opening key is always in a trigger state in the duration t, the control module drives the door body of the intelligent household appliance body to be opened when the duration reaches t. In general, t may be 1 to 30 seconds. It can be understood that if the trigger of the door opening button is turned off before the time period t is not reached, the timer is cleared, and the control module does not drive the door body to be opened. And when the control module detects that the door opening key is triggered again, timing is repeated. Therefore, the door body switch can be prevented from being driven due to false triggering of a user, on one hand, the energy consumption of the intelligent household appliance can be saved, and on the other hand, the user experience can be improved.
It can be understood that when a plurality of door bodies are arranged on one intelligent household appliance body, each door body is correspondingly provided with a door opening device, and a timer corresponding to each door body is arranged in the control module and used for independently timing the corresponding door body. In general, the number of door openers is 1 to 10.

and the loudspeaker is used for playing the voice prompt information corresponding to the voice instruction when receiving the voice instruction.
When the control module determines that the door body is in a door closing state, the timer starts timing, and meanwhile, the control module sends a voice instruction to the loudspeaker so that the loudspeaker plays voice prompt information corresponding to the voice instruction to prompt a user to open the door, so that the user is prompted to prepare to put in or take out an article, and stands at a proper position so as to avoid blocking the opening of the door body, and further improvement of user experience is facilitated.
In one embodiment of the present invention, the infrared sensor 101 is further configured to collect motion sensing information of a user corresponding to the human body sensing information when the presence of the human body sensing information in the first designated area is detected, and send the collected motion sensing information to the control module 103;
the control module 103 is configured to analyze the motion sensing information by using a preset image analysis system, and determine a trigger position of the user; and when the trigger position is in the second designated area, determining a target function key corresponding to the trigger position according to the position information corresponding to each function key.
When the infrared sensor detects that the user approaches the intelligent household appliance body, the action induction information of the user is collected, and then the control module can analyze the action induction information by utilizing the image analysis system so as to determine the triggering position of the user. For example, when the user stands at the point a in the first designated area, the infrared sensor can detect that the user is close to the intelligent household appliance body, at this moment, the infrared projection device projects at least one function key in the second designated area, then the user lifts the leg to trigger the point B in the second designated area, then the infrared sensor sends the action induction information triggered by the user lifting the leg to the control module, and the control module analyzes information such as the action amplitude of the user by utilizing the image analysis system so as to determine the triggering position of the user. And then determining the target function key corresponding to the triggering position according to a preset projection distribution template of each function key. Therefore, the target function key triggered by the user can be accurately determined, and false triggering caused by confirmation deviation of the triggering position is avoided, so that the user experience is improved.
Specifically, the control module 103 is configured to construct a rectangular coordinate system corresponding to the second specified area; determining a projection area corresponding to each function key and an endpoint coordinate of an endpoint corresponding to each projection area in the rectangular coordinate system according to the number of the function keys and a preset arrangement template; determining a target function key corresponding to the trigger position from the function keys by using the following first calculation formula or second calculation formula;
the first calculation formula includes:
wherein M represents a projection area corresponding to the target function key, and (x, y) represents coordinates of the trigger position in the rectangular coordinate system; (x) ij ，y ij ) Endpoint coordinates characterizing the ith endpoint of the jth projected area, n j Characterizing a total number of endpoints of the jth projection region;
the second calculation formula includes:
wherein M represents a projection area corresponding to the target function key, and (x, y) represents coordinates of the trigger position in the rectangular coordinate system; (x) ij ，y ij ) Endpoint coordinates characterizing the ith endpoint of the jth projected area, n j The total number of endpoints of the jth projection region is characterized.
The distance between the triggering position and the projection area corresponding to each function key is determined, and then the function key corresponding to the projection area with the closest triggering position is used as the target function key according to the determined distance, so that the accuracy of determining the target function key is further improved.
