An air conditioner 100 provided by an embodiment of the present disclosure is described with reference to FIG. 1 to FIG. 11, and the air conditioner 100 may be a split air conditioner or an integral air conditioner. A split air conditioner is taken as an example to explain hereinafter.
With reference to FIG. 1, the air conditioner 100 includes a machine body 110, the machine body 110 is a wall-mounted indoor machine. The machine body 110 is capable of realizing different working modes such as cooling and heating. The machine body 110 is provided with a surface frame 111, and a panel 112 connected to the surface frame 111. The panel 112 is located on a front side surface of the machine body 110, and the panel 112 is movably connected with the surface frame 111, so that the panel 112 is capable of being opened or closed. A fresh air module 200 is mounted in the machine body 110, the fresh air module 200 is communicated with an outdoor environment through an air pipe 240, and the outdoor fresh air is introduced into an indoor environment through the air pipe 240, so to ensure a freshness of indoor air, which is beneficial for reducing a concentration of indoor carbon dioxide, and achieving a fresh air effect in the indoor environment. The panel covers the surface frame 111 and is capable of shielding the fresh air module 200 in response to the panel 112 being closed, so that the fresh air module 200 is concealed on an inner side the panel 112, without affecting an appearance of the wall-mounted indoor machine.
With reference to FIG. 1, FIG. 2, FIG. 5 and FIG. 6, the fresh air module 200 includes a housing 210, a fan 230 and a purification assembly 220. The fan 230 and the purification assembly 220 are mounted in the housing 210. The fan 230 is configured to suck the outdoor fresh air into the housing 210 through the air pipe 240, and the air is purified and filtered by the purification assembly 220 and then discharged into the indoor environment, thus improving an air freshness and a comfort of the indoor environment. The purification assembly 220 is movably connected with the housing 210, the housing 210 is provided with an opening matched with the purification assembly 220, and the purification assembly 220 may be inserted into or removed out of the housing 210 through the opening, so that the purification assembly 220 is convenient to disassemble and replace. The fan 230 includes a wind wheel 232 and a motor 231, the motor 231 is fixedly connected with the housing 210, and the wind wheel 232 is driven to rotate at a high speed with the motor 231, so that the outdoor air is capable of entering the housing 210 through the air pipe 240. In the embodiment, the wind wheel 232 may be a centrifugal wind wheel, and the centrifugal wind wheel has the characteristics of large air volume, large air pressure, short ventilation time and the like, thus being beneficial for improving a ventilation efficiency of fresh air.
With reference to FIG. 1 and FIG. 2, it can be understood that the fresh air module 200 is mounted in the machine body 110. When the purification assembly 220 needs to be replaced, the panel 112 is opened first and then the purification assembly 220 is removed out of the housing 210 for replacement, and the panel 112 is closed after the replacement of the purification assembly 220 is finished. During running of the fresh air module 200, the wind wheel 232 is in a high-speed rotating state, and there is a risk of injury caused by touching the wind wheel 232 in the high-speed rotating state with fingers when replacing the purification assembly 220. In the embodiment, the detection device is used to detect the position state of the panel 112 to determine whether the panel 112 is open or closed, when the panel 112 is opened, the panel 112 may trigger the detection device, and the air conditioner 100 controls the fan 230 to stop running. It can be understood that the panel 112 needs to be opened when replacing the purification assembly 220. Therefore, during running of the fresh air module 200, when the detection device detects that the panel 112 is opened, it can be considered that a user needs to replace the purification assembly 220, and at the moment, the motor 231 is controlled to stop running, so that the wind wheel 232 stops rotating, thus reducing a risk of touching the wind wheel 232 in the high-speed rotating state with fingers or other objects, playing an effective protection role on the user and the wind wheel 232, effectively improving the safety of the fresh air module 200 when replacing the purification assembly 220, and being more practical and reliable.
With reference to FIG. 1 and FIG. 3, it should be noted that, in the embodiment, the detection device is mounted in the machine body 110, and the detection device is located at a position of the surface frame 111, so that the detection device is capable of accurately detecting a position change of the panel 112. In an embodiment, the detection device may be a position sensor, and the position sensor is used to detect position information of the panel 112, and when the panel 112 is far away from the surface frame 111, it can be determined according to a detection signal that the panel 112 is opened, so that a position state of the panel 112 is detected. Certainly, the detection device is not limited to the position of the surface frame 111, and may also be mounted on the panel 112, and the detection device is not limited to the position sensor and may also be a position switch 300.
In addition, a principle of controlling the fan 230 to stop running by the air conditioner 100 may be as follows: when the panel 112 is opened, the detection device is triggered to send out a control signal, a control circuit board of the air conditioner 100 may receive the control signal, and the motor 231 is controlled to be powered off according to the control signal, so that the motor 231 stops running, so as to make the wind wheel 232 stop rotating, thus achieving the purpose of making the wind wheel 232 stop rotating when replacing the purification assembly 220; alternatively, after the detection device is triggered, the motor 231 is directly controlled to be powered off, so as to make the motor 231 stop running, thus achieving the purpose of making the fan 230 stop running. A specific control process will not be repeated.
It can be understood that, after the purification assembly 220 is replaced, the detection device may be triggered in response to the panel 112 being closed, and the air conditioner 100 controls the fan 230 to recover the running state, so that during running of the fresh air module 200, thus reducing the risk of injury caused by touching the wind wheel 232 in the high-speed rotating state with fingers when replacing the purification assembly 220, and the fan automatically resumes the running state after the purification assembly 220 is replaced, thus being safe, reliable and more practical. It should be noted that, when the air conditioner 100 is turned off, the fresh air module 200 is turned off, and thus the fan 230 isn't in a running operation. At the moment, it is not necessary to control the wind wheel 232 to stop rotating when replacing the purification assembly 220, and the detection device may be in a standby state.
With reference to FIG. 3 and FIG. 4, the panel 112 and the surface frame 111 are fixed by buckling, where an upper end of the panel 112 is hinged with the surface frame 111, so that the panel 112 is capable of rotating around a hinge point, and the panel 112 may be opened or closed. A back surface of the panel 112 is provided with a buckle 1122 close to a bottom end position, the surface frame 111 is provided with a clamping groove 1111 adapted with the buckle 1122, and when the panel 112 is closed, the buckle 1122 is inserted into the clamping groove 1111 for buckling, so that the panel 112 is capable of being buckled on the surface frame 111. It can be understood that the panel 112 is capable of being positioned through buckling realized by matching between the buckle 1122 and the clamping groove 1111, and when the panel 112 needs to be opened, only the buckle 1122 needs to be separated from the clamping groove 1111, thus being simple and convenient in operation, and being beneficial for improving an efficiency of replacing the purification assembly 220.
It should be noted that, the buckle 1122 may also be arranged on the surface frame 111, the back surface of the panel 112 is provided with the clamping groove 1111 at the same time, and the panel 112 is fixed on the surface frame 111 through buckling realized by matching between the buckle 1122 and the clamping groove 1111, which is different from the embodiment shown in FIG. 1 and FIG. 2 in that positions of the buckle 1122 and the clamping groove 1111 are interchanged. A specific structure is not shown in the accompanying drawings, which will not be repeated herein.
With reference to FIG. 7, FIG. 8 and FIG. 9, in another embodiment, the detection device is mounted on the housing 210 of the fresh air module 200, and a position state of the purification assembly 220 is detected by the detection device, which means that whether the purification assembly 220 is located in the housing 210 is detected. When the purification assembly 220 needs to be replaced, the purification assembly 220 is directly pulled out of the housing 210, and then the replaced purification assembly 220 is reinserted into the housing 210. It can be understood that, during running of the fresh air module 200, the detection device may be triggered in response to the purification assembly 220 being removed out of the housing 210, at the moment, it is judged that the purification assembly 220 is in a state of being separated from the housing 210, and the motor 231 is controlled to stop running, so that the wind wheel 232 stops rotating, thus decreasing a risk of touching the wind wheel 232 in the high-speed rotating state with fingers or other objects, playing an effective protection role on the user and the wind wheel 232, and effectively improving the safety of the fresh air module 200 when replacing the purification assembly 220.
It can be understood that, when the detection device is mounted in the housing 210, a position state of the purification assembly 220 is capable of being directly detected, and only when the purification assembly 220 is replaced during running of the fresh air module 200, and the panel 112 is opened to pull the purification assembly 220 out of the housing 210, the detection device may be triggered, thus making the fan 230 stop running, which means that, when the purification assembly 220 is removed out of the housing 210, it is considered that a user is replacing the purification assembly 220. However, in the case that only the panel 112 is opened and the purification assembly 220 is not pulled out, the fan 230 keeps running, and whether the user is replacing the purification assembly 220 can be accurately identified, thus being more reasonable in structure, and more practical and reliable.
The detection device is mounted on an inner side of the housing 210, so that the detection device is capable of accurately detecting a position change of the purification assembly 220. In an embodiment, the detection device may be a position sensor, the position sensor is used to detect a position of the purification assembly 220, when the purification assembly 220 is pulled out, the purification assembly 220 is far away from the position sensor, and at the moment, it can be judged according to a detection signal that the purification assembly 220 is removed out of the housing 210, so as to control the fan 230 to stop running. The detection device is not limited to the position sensor, and may also be a position switch 300, and the like. A principle of controlling the fan 230 to stop running by the air conditioner 100 may refer to the control principle of the embodiment shown in FIG. 1 and FIG. 2, which will not be repeated herein.
With reference to FIG. 8 and FIG. 9, specific description is made by taking the detection device mounted in the housing 210 as an example, the detection device used in the embodiment is the position switch 300, and the position switch 300 includes a first electrode 310, a second electrode 320, a conductive member 330 and an elastic member, where the conductive member 330 is configured to connect the first electrode 310 and the second electrode 320, the conductive member 330 is movably arranged on the inner side of the housing 210, and the conductive member 330 is connected with the elastic member. When the purification assembly 220 is mounted in the housing 210, the conductive member 330 abuts against the purification assembly 220, and the conductive member 330 is capable of being triggered in response to the purification assembly 220 being removed out of or inserted into the housing 210. The conductive member 330 has a conductive function, and the first electrode 310 and the second electrode 320 are connected or disconnected through the conductive member 330 under an elastic function of the elastic member, so that the fan 230 is controlled to start running by connecting the first electrode 310 and the second electrode 320, or stop running by disconnecting the first electrode 310 and the second electrode 320, thus playing a role of on-off control.
With reference to FIG. 10 and FIG. 11, in the embodiment, each of the first electrode 310 and the second electrode 320 is connected with a control circuit board of the machine body 110. A spring 340 is used as the elastic member, one end of the spring 340 is connected with the housing 210, the other end of the spring is connected with the conductive member 330. The conductive member 330 is provided with contact points 331 corresponding to the first electrode 310 and the second electrode 320. When the purification assembly 220 is removed out of the housing 210, the purification assembly 220 is separated from the conductive member 330, and at the moment, the conductive member 330 is pushed to move under the elastic function of the elastic member, so that the conductive member 330 is contacted with the first electrode 310 and the second electrode 320 at the same time, thus the first electrode 310 and the second electrode 320 is connected. The control circuit board controls the fan 230 to stop running after receiving a connecting signal of the position switch 300, so that during running of the fresh air module 200, the wind wheel 232 is capable of being controlled to stop running in response to the purification assembly 220 being removed out of the housing 210, thus avoiding fingers or other objects from touching the wind wheel 232 in the high-speed rotating state, playing an effective protection role and effectively improving the safety of the fresh air module 200 when replacing the purification assembly 220.
With reference to FIG. 11, after the purification assembly 220 is replaced, when the purification assembly 220 is reinserted into the housing 210 and reaches a mounting position, that is, when the purification assembly 220 is mounted in place, the purification assembly 220 presses the conductive member 330, so that the contact points 331 of the conductive member 330 are separated from the first electrode 310 and the second electrode 320, thus the first electrode 310 and the second electrode 320 is disconnected and the first electrode and the second electrode will be kept in a disconnected state. The control circuit board controls the fan 230 to start running after receiving a disconnecting signal of the position switch 300, and the fan 230 recovers the running state, thus ensuring that the fresh air module 200 is capable of keeping the running state after the purification assembly 220 is replaced.
With reference to FIG. 10 and FIG. 11, in the embodiment, the purification assembly 220 is provided with a trigger member 360. When the purification assembly 220 is mounted in the housing 210, the trigger member 360 is capable of pushing the conductive member 330 to be separated from the first electrode 310 and the second electrode 320, thus turning off the position switch 300. When the purification assembly 220 is removed out of the housing 210, the trigger member 360 is far away from the conductive member 330, so that the conductive member 330 moves towards the first electrode 310 and the second electrode 320 under a function of the spring 340, thus turning on the position switch 300.
It should be noted that, the purification assembly 220 may have structural components such as an electrostatic purification assembly, a high efficiency air filter and an activated carbon filter mesh, which are not specifically limited herein. The purification assembly 220 of the embodiment includes a purification mesh 221 and a mounting frame 222. The purification mesh 221 is fixedly mounted on the mounting frame 222, the purification mesh 221 is mounted in the housing 210 by the mounting frame 222 or the purification mesh 221 is pulled out of the housing 210. The trigger member 360 is arranged on the mounting frame 222. In an embodiment, it is understandable that the trigger member 360 forms a contact protruding from an outer side wall of the mounting frame 222, the contact is not limited to a specific shape. The trigger member 360 is located at a position corresponding to the conductive member 330, and when the purification assembly 220 is inserted and mounted in place, the trigger member 360 is capable of correspondingly pushing the conductive member 330 to move towards one side of the spring 340, so that the trigger member 360 and the conductive member 330 are positioned more accurately, thus having a practical and reliable structure.
With reference to FIG. 10 and FIG. 11, a through hole 350 corresponding to the trigger member 360 is arranged in the housing 210. The through hole 350 provides a guiding function for the trigger member 360, and when the purification assembly 220 is inserted into the housing 210, the trigger member 360 and the conductive member 330 are capable of being quickly positioned through the through hole 350, so that the trigger member 360 accurately pushes the conductive member 330 to move, thus further improving structural stability and reliability. It is understandable that, a shape of the trigger member 360 is matched with a shape of the through hole 350. In some embodiments, the trigger member 360 and the through hole 350 are both circular, which will not be repeated.

step S111: recording a current rotating speed of the fan 230;
step S210: controlling the fan 230 to stop running in response to the purification assembly 220 being removed out of the housing 210; and
step S211: controlling the fan 230 to start and resume running at the current rotating speed in response to the purification assembly 220 being reset.

It is understandable that, after the purification assembly 220 is replaced, when the purification assembly 220 is reinserted into the housing 210 and mounted in place, the purification assembly 220 may trigger the position switch 300 to turn off, and at the moment, the fan 230 is controlled to start running by a control circuit, so that the fan 230 is capable of running again, thus ensuring that the fresh air module 200 is capable of keeping the running state after the purification assembly 220 is replaced.
It should be noted that, the motor 231 of the fan 230 has different driving frequencies, and the wind wheel 232 has different rotating speeds at different driving frequencies. The fresh air module 200 may choose different rotating speeds for ventilation according to use requirements of the user, thus being more comfortable to use. In an embodiment, the fan 230 includes three different rotating speed gears of high, medium and low rotating speed gears, the higher the rotating speed gear is, the greater the air volume is and the higher the ventilation efficiency is, and when the fresh air module 200 is turned on, the fan 230 runs at the high rotating speed gear. At the moment, a current rotating speed of the fan 230 is recorded as the high rotating speed gear, when replacing the purification assembly 220, the fan 230 is controlled to stop running, and after the purification assembly 220 is replaced and reset, the fan 230 is controlled to start and resume running at the recorded current rotating speed, so that the fresh air module 200 is capable of keeping an original running state after the purification assembly 220 is replaced, deterioration of a comfort degree after the purification assembly 220 is replaced is reduced, and a control mode is more reasonable and practical, thus making the user have better use experience and higher use experience.
