And can be adjusted as needed by those skilled in the art to suit particular applications.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a bathroom air conditioner according to an embodiment of the present invention. As shown in fig. 1, the air conditioner 1 includes an air extraction module 11, a room temperature adjustment module 12, and a displacement sensor 13.
The room temperature adjusting module 12 is used for adjusting the indoor temperature inside the toilet, and the room temperature adjusting module 12 generally comprises an air conditioner indoor unit and an air conditioner outdoor unit, the air conditioner outdoor unit is installed outside the toilet, and the air conditioner indoor unit is installed inside the toilet. The air extraction module 11 is used for extracting air in the toilet and exhausting the air to the outside of the toilet, and the air extraction module 11 comprises an air inlet 11a, an axial flow fan 11b and an air outlet pipe 11 c. As an example, the air inlet 11a of the air extraction module 11 is disposed inside a toilet, and the air outlet 11c is connected to an air duct of an outdoor or a building.
Continuing with fig. 2, fig. 2 is a flowchart illustrating main steps of a toilet air conditioner control method according to an embodiment of the present invention. As shown in fig. 2, the toilet air conditioner control method according to the embodiment of the present invention includes:
step S201: acquiring scene information of a toilet through a displacement sensor module;
step S202: and controlling the room temperature adjusting module and/or the air extraction module of the toilet air conditioner to work according to the scene information of the toilet.
In step S201, the toilet scene information generally includes information such as the state of a person in the toilet, the position of the person, the residence time of the person, the trajectory of the person, and the state of a toilet door.
In the embodiment of the present invention, preferably, the millimeter wave radar sensor module is used as the displacement sensor 13. The millimeter wave radar sensor has the advantages of mature technology, high human body detection accuracy, capability of better protecting the privacy of a user and the like, and is a technical scheme with high cost performance.
The information such as the shape of the bathroom, the overall dimension of the bathroom equipment and the position of the bathroom equipment in the bathroom can be acquired through the millimeter wave radar sensor module. By matching with a special APP of an intelligent terminal which is in wireless connection (such as Wi-Fi network and Bluetooth communication) with the bathroom air conditioner 1, a user can mark the positions of bathroom facilities such as a bathroom door, a closestool and a hand basin in the detection result of the millimeter wave radar sensor module according to the actual situation in the bathroom, so that a bathroom internal facility position distribution map containing the bathroom facilities is obtained.
According to the human body detection data acquired by the millimeter wave radar sensor, whether a person enters the toilet or not can be detected, so that the state of the person in the toilet is obtained, and the position of the person in the toilet is acquired. Meanwhile, the personnel track can be obtained according to the historical change data of the personnel position, and the personnel residence time of each appointed position in the bathroom is respectively obtained by counting the residence time of the personnel in each bathroom facility area in the bathroom.
Further, since the millimeter wave radar sensor can detect the shape of the object, the state of the toilet door can be obtained by detecting the change of the radar echo in the toilet door area after the position of the toilet door is determined. As an example, when the toilet door is closed, the toilet door area is detected as a closed area; when the toilet door is opened, the toilet door area is detected as an open area.
In step 202, the bathroom air conditioner 1 may control the air extraction module 11 and/or the room temperature adjusting module 12 to operate according to the bathroom scene information acquired in step S201.
In the embodiment of the present invention, as shown in fig. 3, when a person opens a door of a toilet to enter the toilet, the air conditioner 1 of the toilet may control the pumping module 11 and/or the room temperature adjusting module 12 to operate according to the state of the door of the toilet, the person's trajectory, and the person's residence time.
Usually, the toilet door is in a closed state, when personnel need to open the toilet door to enter the toilet, the millimeter wave radar sensor module detects that the state of the toilet door is changed from the closed state to an open state, and then further detects whether the personnel enter the toilet. After personnel enter the toilet, the personnel state in the toilet is changed from an unmanned state to a manned state, the millimeter wave radar sensor acquires and records the personnel position and the personnel track in real time, and the personnel residence time in different places is respectively timed according to the different personnel positions.
In the embodiment of the invention, after the personnel enter the toilet, the second personnel residence time timing is started immediately, and the second personnel residence time is the residence time of the personnel in the toilet area. When the personnel position is in the toilet bowl area, starting a first personnel residence time timer, wherein the first personnel residence time is the residence time of the personnel position in the toilet bowl area.
It is understood from the meaning of the first person residence time and the second person residence time that the second person residence time is started earlier than the first person residence time, and the second person residence time is ended later than the first person residence time (the time when the person leaves the toilet), so that the second person residence time is usually longer than the first person residence time.
When the person track is detected to move from the door position to the toilet position, the room temperature adjusting module 12 and/or the air suction module 11 of the toilet air conditioner 1 are controlled to work according to the first person residence time and the second person residence time.
And when the residence time of the second person is greater than or equal to the second time threshold, controlling the room temperature adjusting module 12 to start working according to the environmental temperature parameter preset by the user. When the residence time of the first person in the toilet bowl area is greater than or equal to the first time threshold value, the air exhaust module 11 can be selectively started according to the setting of the user, so that the peculiar smell generated when the person goes to the toilet can be discharged out of the toilet, the user experience is improved, and the comfort of the user is improved. As an example, in hot summer or cold winter, the environmental temperature in the toilet is preferably guaranteed, in which case the first time threshold may be set to 10 seconds, the second time threshold may be set to 5 seconds, and the person enters the toilet and then turns on the room temperature adjusting module 12 first. In spring festival or autumn with proper temperature, the room temperature adjusting module 12 can be started in a delayed mode or the operation mode of the room temperature adjusting module 12 can be controlled through the setting of the second time threshold and/or the ambient temperature parameter of the air conditioner, unnecessary air conditioner refrigeration or heating is reduced, and the purpose of energy conservation is achieved.
Preferably, the operating power of the air extraction module can be controlled in accordance with the first person dwell time. Generally, the time for a person to urinate is short, the peculiar smell is small, and when the person defecates, the time is long, the peculiar smell is large, therefore, when the residence time of the first person is less than or equal to the ninth time threshold, the person is considered to urinate, the air exhaust module 11 works at the first operation power, the power is small, and the rotating speed of the axial flow fan 11b is low; when the residence time of the first person is longer than the ninth time threshold, the person is considered to be defecating, the air exhaust module 11 works at the second operation power, the power is higher, the rotating speed of the axial flow fan 11b is higher, and the discharge of peculiar smell can be accelerated, so that the user experience is further improved, and the comfort of the user is improved.
Preferably, the bathroom air conditioner 1 can continuously detect the residence time of the second person, and when the residence time of the second person is greater than the alarm time threshold, the bathroom air conditioner 1 can send alarm information to the user to prompt that an accident may occur in the bathroom. As an example, the bathroom air conditioner 1 may perform data interaction with a smartphone through a home Wi-Fi network and/or a 4G/5G public network, when a solitary old person falls down in a bathroom and cannot get up, the displacement sensor module 13 may detect that a person is in the bathroom for a long time, and the position or trajectory of the person does not change, and when a set alarm time threshold is exceeded, for example, 1 hour, the bathroom air conditioner 1 may send an alarm message to a child of the old person or a set community service person, so as to prompt the old person that an unexpected situation may occur in the bathroom, please confirm and rescue in time, and provide a safety service for a specific group of people.
In another embodiment, the operation of the room temperature adjusting module 12 and/or the suction module 11 of the room air conditioner 1 is controlled directly according to the first and second human residence times without detecting the state of the door of the toilet. The positions of the personnel are detected in real time through the millimeter wave radar sensor module, and the residence time of the personnel is timed. When the first person residence time is greater than or equal to the fifth time threshold, controlling the air exhaust module 11 to start working; and when the residence time of the second person is greater than or equal to the sixth time threshold, controlling the room temperature adjusting module 12 to start working according to the preset ambient temperature. The size of the fifth time threshold and the sixth time threshold can be set according to actual conditions.
The person has entered the toilet and the room temperature regulating module 12 and/or the control pumping module 11 has been switched on.
