Detailed Implementation

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] It is important to understand that air conditioner 1 can be an indoor standing air conditioner 1. The traditional anti-pinch function is usually set in the main control program of the standing air conditioner 1 to open a certain distance when the door is almost closed after shutting down, so as to remind the user that the door is about to be closed. Finally, the door is completely closed. This process only applies to the shutdown state. The anti-pinch function cannot be performed during normal use of the machine.

[0042] An air conditioner 1 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0043] like Figures 1-19 As shown, the air conditioner 1 according to an embodiment of the present invention is an indoor standing air conditioner 1. The air conditioner 1 includes a casing 100, an air guide component 200, a drive device 300, an anti-pinch device 400, and a control device 500. It should be understood that the air conditioner 1 has a cooling mode and a heating mode, that is, the air conditioner 1 can blow out cold air or hot air through the air outlet 101. The following description takes the example of the air conditioner 1 blowing out cold air from the air outlet 101 in cooling mode.

[0044] In some embodiments, the housing 100 has an air outlet 101, and the air guide component 200 is movably disposed in the air outlet 101. For example, the air guide component 200 can rotate and / or translate within the air outlet 101. A drive device 300 is drivenly connected to the air guide component 200, and the drive device 300 is used to drive the air guide component 200 to move. An anti-pinch device 400 is used to detect whether there is a foreign object between the air guide component 200 and the edge of the air outlet 101, and emits a first signal when a foreign object is detected between the air guide component 200 and the edge of the air outlet 101. A control device 500 is communicatively connected to the anti-pinch device 400, and after receiving the first signal, the control device 500 controls the drive device 300 to drive the air guide component 200 to move away from the foreign object.

[0045] According to an embodiment of the present invention, the air conditioner 1, by providing an air guide component 200 and a driving device 300, can drive the air guide component 200 to accurately and reliably guide the air outlet of the air conditioner 1, so as to smoothly deliver the cold air to a predetermined area outside the air conditioner 1, improve the cooling effect of the air conditioner 1, and improve the user's comfort.

[0046] Furthermore, by setting up an anti-pinch device 400 and a control device 500, when the anti-pinch device 400 detects a foreign object between the air guide component 200 and the edge of the air outlet 101, it can send a first signal to the control device 500. After receiving the first signal, the control device 500 will control the drive device 300 to drive the air guide component 200 to move away from the foreign object. This prevents foreign objects from being clamped between the air guide component 200 and the edge of the air outlet 101. Therefore, setting up the anti-pinch device 400 can improve the safety performance of the air conditioner 1. For example, when the foreign object is a user's finger, it can prevent the user's finger from being pinched, improving user safety and comfort. At the same time, it can protect the air conditioner 1 itself, preventing foreign objects from affecting the movement of the air guide component 200 or even damaging it, thus improving the safety and reliability of the air conditioner 1.

[0047] Therefore, the air conditioner 1 according to the embodiment of the present invention has advantages such as good operational protection, effective prevention of hand pinching, and user comfort and convenience.

[0048] An air conditioner 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] In some specific embodiments of the present invention, such as Figures 1-19 As shown, the air conditioner 1 according to an embodiment of the present invention is an indoor standing air conditioner 1, which includes a housing 100, an air guide component 200, a drive device 300, an anti-pinch device 400, and a control device 500.

[0050] In some embodiments of the present invention, such as Figure 5 As shown, the air guiding component 200 includes an air guiding plate 210, which extends in the vertical direction (as shown in the figure). Figure 1 As shown, the air guide plate 210 is rotatably mounted on the housing 100, and the rotation axis of the air guide plate 210 extends in the vertical direction. One edge of the air guide plate 210 extending along its length and the edge of the air outlet 101 define a first mating gap 102. The anti-pinch device 400 issues a first signal after detecting a foreign object in the first mating gap 102. This prevents foreign objects from being clamped between the air guide plate 210 and the edge of the air outlet 101, improving anti-pinch performance.

[0051] In some optional examples, such as Figure 11 As shown, the air outlet 101 is located on the front surface of the housing 100 (front-to-back direction as shown). Figure 1 As shown), the air guiding component 200 includes an air guiding plate 210 extending vertically along its length. First mating gaps 102 are defined between the left edge of the air guiding plate 210 and the left edge of the air outlet 101, and between the right edge of the air guiding plate 210 and the right edge of the air outlet 101, respectively (in the left-right direction as shown). Figure 1As shown, the anti-pinch device 400 issues a first signal after detecting at least one foreign object in the first mating gap 102. This prevents fingers from being pinched between the edge of the air outlet 101 and the left and right sides of the air guide plate 210, thus improving the anti-pinch performance.

[0052] For example, the first mating gap 102 includes a first left mating gap and a first right mating gap. A first left mating gap is formed between the left edge of the air guide plate 210 and the left edge of the air outlet 101, and a first right mating gap is formed between the right edge of the air guide plate 210 and the right edge of the air outlet 101. The first signal includes a first left signal and a first right signal. After the anti-pinch device 400 detects a foreign object in the first left mating gap, it issues a first left signal, and then the control device 500 controls the drive device 300 to drive the air guide assembly to rotate to the right. After the anti-pinch device 400 detects a foreign object in the first right mating gap, it issues a first right signal, and then the control device 500 controls the drive device 300 to drive the air guide assembly to rotate to the left.

[0053] In some alternative embodiments, such as Figure 5 As shown, the air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side. The anti-pinch device 400 is also used to detect whether there is a foreign object between the first air guide plate 211 and the second air guide plate 212, and to issue a second signal when a foreign object is detected between the first air guide plate 211 and the second air guide plate 212. After receiving the second signal, the control device 500 controls the drive device 300 to drive at least one of the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object. This can prevent foreign objects from being stuck between the first air guide plate 211 and the second air guide plate 212.

[0054] In some specific embodiments, such as Figure 5 As shown, one edge of the first air guide plate 211 extending along the length direction and one edge of the second air guide plate 212 extending along the length direction define a second mating gap 103. The anti-pinch device 400 issues a second signal after detecting a foreign object in the second mating gap 103. This prevents foreign objects from being trapped in the second mating gap 103.

[0055] In some specific examples, the air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side, with a second mating gap 103 between the first air guide plate 211 and the second air guide plate 212. When the anti-pinch device 400 detects a foreign object in the second mating gap 103, it sends a second signal to the control device 500. After receiving the second signal, the control device 500 controls the drive device 300 to drive the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object, respectively. This effectively prevents foreign objects from being trapped between the first air guide plate 211 and the second air guide plate 212.

[0056] In some embodiments of the present invention, such as Figures 4-17 As shown, the anti-pinch device 400 is a current detection device, which includes a detection module with a detection circuit. The detection module includes a first conductive element 410, a second conductive element 420, and a communication module 430. The first conductive element 410 is located on the outer edge of the air guide component 200 and is connected to the detection circuit. The second conductive element 420 is located on the edge of the air outlet 101 and is also connected to the detection circuit. The communication module 430 is electrically connected to the detection circuit. When the foreign object is conductive and is in contact with both the first conductive element 410 and the second conductive element 420, the detection circuit is activated, and the communication module 430 sends a signal. This allows for the detection of foreign objects using current, providing accurate and reliable results, avoiding blind spots, and the anti-pinch device 400 is low-cost, eliminating the need for dedicated radar or infrared detectors.

[0057] In other words, the anti-pinch device 400 is a current detection device. The anti-pinch device 400 has a detection circuit. The first conductive element 410 and the second conductive element 420 are respectively connected to the detection circuit. Since the first conductive element 410 and the second conductive element 420 are always in a spaced-out state, the detection circuit is in an open state. When a conductive foreign object comes into contact with the first conductive element 410 and the second conductive element 420 respectively, the detection circuit is turned on. The communication module 430 is electrically connected to the detection circuit. After the communication module 430 detects that the detection circuit is turned on, it sends a first signal or a second signal to the control device 500.

[0058] In some specific examples, the first conductive element 410 is formed as a first metal decorative edge, which extends along the outer periphery of the air guide component 200. The second conductive element 420 is formed as a second metal decorative edge, which extends along the periphery of the air outlet 101. This not only facilitates the formation of the detection circuit but also makes the appearance of the air conditioner 1 more aesthetically pleasing.

[0059] In a further embodiment, the first mating gap 102 and / or the second mating gap 103 are greater than or equal to 3 mm. This ensures that there will be no contact between the edge of the air guide plate 210 and the air outlet 101, and between the first air guide plate 211 and the second air guide plate 212, thus preventing short circuits and improving the safety performance of the anti-pinch device 400.

[0060] Optionally, such as Figure 11As shown, the detection module also includes a third conductive element 440, which is disposed in the housing 100. The third conductive element 440 is connected to the detection circuit and is electrically connected to the first conductive element 410 and the second conductive element 420 respectively. The third conductive element 440 is also electrically connected to the communication module 430. This allows a detection circuit to be formed between the first conductive element 410, the second conductive element 420, and the third conductive element 440, and facilitates the electrical connection between the detection circuit and the communication module 430.

[0061] In some specific examples, such as Figure 11 As shown, the housing 100 has a through-hole 104, within which a display panel assembly can be installed. A third conductive element 440 is formed as a third metal decorative edge, extending along the periphery of the through-hole 104. The third metal decorative edge contacts and engages with the second metal decorative edge, and is electrically connected to the first metal decorative edge. This further facilitates the formation of the detection circuit and the decoration of the air conditioner 1.

[0062] Optionally, such as Figure 13 and Figure 14 As shown, the detection module also includes a rotating arm 450 and a conductive brush 460. The rotating arm 450 is electrically connected to the first conductive element 410, and the air guide component 200 is connected to the drive device 300 through the rotating arm 450. The conductive brush 460 is electrically connected to the third conductive element 440, and the rotating arm 450 and the conductive brush 460 are in contact. This not only enables the electrical connection between the third conductive element 440 and the first conductive element 410, but also allows the conductive brush 460 to block the gap between the first conductive element 410 and the air outlet 101, achieving both dust prevention and aesthetic enhancement.

[0063] Optionally, the conductive brush 460 can be a carbon brush.

[0064] Specifically, multiple rotating arms 450 are respectively located at the upper and lower ends of the air guide plate 210. At least a portion of each rotating arm 450 is a conductive part, which is connected to the first metal decorative edge. The air guide plate 210 is connected to the driving device 300 through the rotating arms 450, so that the driving device 300 can drive the air guide plate 210 to rotate. A conductive brush 460 is located on and electrically connected to the third conductive element 440. During rotation, the conductive part of the rotating arm 450 located at the upper end of the air guide plate 210 is always in contact with the conductive brush 460. This not only achieves electrical connection between the third conductive element 440 and the first conductive element 410, but also allows the conductive brush 460 to block the gap between the first conductive element 410 and the air outlet 101, achieving both dust prevention and aesthetic effects.

[0065] Optionally, the communication module 430 includes a cover 431, a body 432, and a circuit board 433. The cover 431 and the body 432 define an installation space. The circuit board 433 is installed in the installation space. A conductive brush 460 is disposed on the circuit board 433. The circuit board 433 is electrically connected to a third conductive element 440 through a connecting post.

[0066] In some optional examples, the detection circuit operates at a voltage of less than 24V and a current of less than 0.1A. This ensures user safety and prevents accidents when the user touches the anti-pinch device 400.

[0067] In a specific example of the present invention, the air guide assembly extends vertically. A conductive first metal decorative edge, which is an aluminum alloy decorative frame, is designed around the outer contour of the air guide plate 210. The front side of the housing 100 has an air outlet 101, and the edge of the air outlet 101 is designed with a second metal decorative edge, which is also an aluminum alloy decorative frame. The housing 100 also has a through-hole, into which a display panel can be assembled. A third metal decorative edge, also an aluminum alloy frame, is designed around the through-hole. The rotating arm 450 is designed as a sheet metal structure and connected to the edge of the air guide plate 210. An anti-pinch control system, including a communication module 430, is installed below the through-hole. When the left and right air guide plates 210 move, the machine is turned on, or the machine is turned off, there is no contact between the two air guide plates 210 or between the air guide plate 210 and the air outlet 101, thus creating a circuit break. The first air guide plate 211 is the left air guide plate 210, and the second air guide plate 212 is the right air guide plate 210. When the left and right air guide plates 210 move, if a person puts their hand into the first mating gap 102 or the second mating gap 103 and is pinched by the air guide plate 210, the detection circuit will be automatically connected to generate current, thereby triggering the communication module 430 to send a signal to the control device 500. The control device 500 is an electrical control box, which in turn controls the drive device 300 to control the air guide plate 210 to move in the opposite direction, thereby effectively preventing the hand from being pinched.

[0068] Specifically, the current-sensing anti-pinch control method of this invention:

[0069] 1. Within the second mating gap 103 between the first air guide plate 211 and the second air guide plate 212, a circuit is formed between the two air guide plates 210. When a hand is placed in the second mating gap 103, both the left and right air guide plates 210 move towards the center. After the left and right air guide plates 210 touch the hand, a complete conductive detection circuit is formed between the left and right air guide plates and the hand, thereby triggering the communication module 430 to send a second signal. When the control device 500 receives the signal, it controls the drive device 300 to move the left and right air guide plates in opposite directions, thereby preventing the hand from being pinched.

[0070] 2. In the first left mating gap between the first air guide plate 211 and the edge of the air outlet 101, when a hand is placed in the first left mating gap, the left air guide plate 210 moves to the left. After the left air guide plate 210 touches the hand, a complete conductive detection circuit is formed between the left air guide plate 210, the hand, and the edge of the air outlet 101, thereby triggering the communication module 430 to send the first left signal. When the control device 500 receives the signal, it controls the drive device 300 to move the left air guide plate 210 in the opposite direction, thereby preventing the hand from being pinched.

[0071] 3. In the first right fitting gap between the second air guide plate 212 and the edge of the air outlet 101, when a hand is placed in the first right fitting gap, the right air guide plate 210 moves to the right. After the right air guide plate 210 touches the hand, the right air guide plate 210, the hand, and the edge of the air outlet 101 are connected to form a complete detection circuit, thereby triggering the communication module 430 to send the first right signal. When the control device 500 receives the signal, it controls the drive device 300 to move the right air guide plate 210 in the opposite direction, thereby preventing the hand from being pinched.

[0072] According to a specific embodiment of the present invention, such as Figures 1-17 As shown, the air conditioner 1 is an indoor standing air conditioner 1, which includes a casing 100, an air guide component 200, a drive device 300, an anti-pinch device 400, and a control device 500. The air conditioner 1 has a cooling mode and a heating mode, that is, the air conditioner 1 can blow out cold air or hot air through the air outlet 101. The following description takes the example of the air conditioner 1 blowing out cold air from the air outlet 101 in cooling mode.

[0073] The housing 100 has an air outlet 101, and an air guide component 200 is movably disposed in the air outlet 101. For example, the air guide component 200 can rotate and / or translate within the air outlet 101. A drive unit 300 is drivenly connected to the air guide component 200, and the drive unit 300 is used to drive the air guide component 200 to move. An anti-pinch device 400 is used to detect whether there is a foreign object between the air guide component 200 and the edge of the air outlet 101, and issues a first signal when a foreign object is detected between the air guide component 200 and the edge of the air outlet 101. A control unit 500 is communicatively connected to the anti-pinch device 400, and after receiving the first signal, the control unit 500 controls the drive unit 300 to drive the air guide component 200 to move away from the foreign object.

[0074] The air guiding component 200 includes an air guiding plate 210, which extends vertically and is rotatably mounted on the housing 100, with its rotation axis extending vertically. A first mating gap 102 is defined between one edge of the air guiding plate 210 extending along its length and the edge of the air outlet 101. The anti-pinch device 400 issues a first signal after detecting a foreign object in the first mating gap 102. This prevents foreign objects from being trapped between the air guiding plate 210 and the edge of the air outlet 101.

[0075] The air outlet 101 is located on the front surface of the housing 100. The air guiding component 200 includes an air guiding plate 210 extending vertically along its length. First mating gaps 102 are defined between the left edge of the air guiding plate 210 and the left edge of the air outlet 101, and between the right edge of the air guiding plate 210 and the right edge of the air outlet 101, respectively. The anti-pinch device 400 issues a first signal after detecting a foreign object in at least one of the first mating gaps 102. This prevents foreign objects from being clamped between the edge of the air outlet 101 and the left and right edges of the air guiding plate 210.

[0076] The air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side. The anti-pinch device 400 is also used to detect whether there is a foreign object between the first air guide plate 211 and the second air guide plate 212, and to issue a second signal when a foreign object is detected between the first air guide plate 211 and the second air guide plate 212. After receiving the second signal, the control device 500 controls the drive device 300 to drive at least one of the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object. This can prevent foreign objects from being stuck between the first air guide plate 211 and the second air guide plate 212.

[0077] The first air guide plate 211 extends along its length, and the second air guide plate 212 extends along its length, defining a second mating gap 103. The anti-pinch device 400 issues a second signal after detecting a foreign object in the second mating gap 103. This prevents foreign objects from being trapped in the second mating gap 103.

[0078] The air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side. A second mating gap 103 exists between the first air guide plate 211 and the second air guide plate 212. When the anti-pinch device 400 detects a foreign object in the second mating gap 103, it sends a second signal to the control device 500. Upon receiving the second signal, the control device 500 controls the drive device 300 to drive the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object, respectively. This effectively prevents foreign objects from being trapped between the first air guide plate 211 and the second air guide plate 212.

[0079] The anti-pinch device 400 is a current detection device, which includes a detection module with a detection circuit. The detection module includes a first conductive element 410, a second conductive element 420, and a communication module 430. The first conductive element 410 is located on the outer edge of the air guide component 200 and is connected to the detection circuit. The second conductive element 420 is located on the edge of the air outlet 101 and is also connected to the detection circuit. The communication module 430 is electrically connected to the detection circuit. When the foreign object is conductive and is in contact with both the first conductive element 410 and the second conductive element 420, the detection circuit is activated, and the communication module 430 sends a signal. This allows for the detection of foreign objects using current, providing accurate and reliable results, avoiding blind spots, and the anti-pinch device 400 is low-cost, eliminating the need for dedicated radar or infrared detectors.

[0080] The first conductive element 410 is formed as a first metal decorative edge, which extends along the outer periphery of the air guide component 200. The second conductive element 420 is formed as a second metal decorative edge, which extends along the periphery of the air outlet 101. This not only facilitates the formation of the detection circuit but also makes the appearance of the air conditioner 1 more aesthetically pleasing.

[0081] The first fitting gap 102 and / or the second fitting gap 103 are greater than or equal to 3mm. This ensures that there will be no contact between the edge of the air guide plate 210 and the air outlet 101, and between the first air guide plate 211 and the second air guide plate 212, which would cause a short circuit and improve the safety performance of the anti-pinch device 400.

[0082] The detection module also includes a third conductive element 440, which is disposed in the housing 100. The third conductive element 440 is connected to the detection circuit and is electrically connected to the first conductive element 410 and the second conductive element 420 respectively. The third conductive element 440 is also electrically connected to the communication module 430. This allows a detection circuit to be formed between the first conductive element 410, the second conductive element 420, and the third conductive element 440, and facilitates the electrical connection between the detection circuit and the communication module 430.

[0083] The housing 100 has a through-hole 104, within which a display panel assembly can be installed. A third conductive element 440 is formed as a third metal decorative edge, extending along the periphery of the through-hole 104. The third metal decorative edge contacts and engages with the second metal decorative edge, and is electrically connected to the first metal decorative edge. This further facilitates the formation of the detection circuit and the decoration of the air conditioner 1.

[0084] The detection module also includes a rotating arm 450 and a conductive brush 460. The rotating arm 450 is electrically connected to the first conductive element 410. The air guide component 200 is connected to the drive device 300 through the rotating arm 450. The conductive brush 460 is located on and electrically connected to the third conductive element 440. The rotating arm 450 and the conductive brush 460 are in contact and engaged. This not only achieves the electrical connection between the third conductive element 440 and the first conductive element 410, but also allows the conductive brush 460 to block the gap between the first conductive element 410 and the air outlet 101, achieving both dust prevention and aesthetic enhancement.

[0085] The detection circuit operates at a voltage of less than 24V and a current of less than 0.1A. This ensures user safety and prevents accidents when the user touches the anti-pinch device 400.

[0086] According to other embodiments of the present invention, such as Figure 18 and Figure 19 As shown, the anti-pinch device 400 is an infrared detection device, comprising an infrared emitting module 470 and an infrared receiving module 480. The infrared emitting module 470 is located at one end of the air outlet 101 along its length and is used to emit infrared signals. The infrared receiving module 480 is located at the other end of the air outlet 101 along its length and is used to receive infrared information. When the infrared signal received by the infrared receiving module 480 changes, the anti-pinch device 400 sends a signal. This allows the infrared detection device to detect the presence of foreign objects. When the infrared signal received by the infrared receiving module 480 changes, it indicates the presence of a foreign object, and the anti-pinch device 400 sends a first signal or a second signal to the control device 500, improving the anti-pinch performance.

[0087] In some optional examples, the anti-pinch device 400 is an infrared detection device. The anti-pinch device 400 includes an infrared emitting module 470 and an infrared receiving module 480. The infrared emitting module 470 is located at the upper end of the air outlet 101 and is used to emit infrared signals. The infrared receiving module 480 is located at the lower end of the air outlet 101 and is used to receive infrared information. When the infrared signal received by the infrared receiving module 480 changes, the anti-pinch device 400 sends a signal. This allows the infrared detection device to detect the presence of foreign objects. When the infrared signal received by the infrared receiving module 480 changes, it indicates the presence of a foreign object, and the anti-pinch device 400 sends a first signal or a second signal to the control device 500.

[0088] In other words, the upper and lower ends of the air guide plate 210 are designed with infrared emitting and receiving devices. When a person's hand is placed within the first mating gap 102 or the second mating gap 103, the infrared reception will be blocked, thereby triggering the communication module 430 to send a signal to the control device 500. The control device 500 is an electrical control box, which then controls the drive device 300 to move the air guide plate 210 in the opposite direction, thus achieving anti-pinch protection. The air conditioner 1 of the present invention has the characteristics of high reliability, good dust prevention effect, good anti-pinch effect, beautiful appearance, and compact structure.

[0089] According to a specific embodiment of the present invention, such as Figures 1-2 , Figures 17-18 As shown, the air conditioner 1 is an indoor standing air conditioner 1, which includes a casing 100, an air guide component 200, a drive device 300, an anti-pinch device 400, and a control device 500. The air conditioner 1 has a cooling mode and a heating mode, that is, the air conditioner 1 can blow out cold air or hot air through the air outlet 101. The following description takes the example of the air conditioner 1 blowing out cold air from the air outlet 101 in cooling mode.

[0090] The housing 100 has an air outlet 101, and an air guide component 200 is movably disposed in the air outlet 101. For example, the air guide component 200 can rotate and / or translate within the air outlet 101. A drive unit 300 is drivenly connected to the air guide component 200, and the drive unit 300 is used to drive the air guide component 200 to move. An anti-pinch device 400 is used to detect whether there is a foreign object between the air guide component 200 and the edge of the air outlet 101, and issues a first signal when a foreign object is detected between the air guide component 200 and the edge of the air outlet 101. A control unit 500 is communicatively connected to the anti-pinch device 400, and after receiving the first signal, the control unit 500 controls the drive unit 300 to drive the air guide component 200 to move away from the foreign object.

[0091] The air guiding component 200 includes an air guiding plate 210, which extends vertically and is rotatably mounted on the housing 100, with its rotation axis extending vertically. A first mating gap 102 is defined between one edge of the air guiding plate 210 extending along its length and the edge of the air outlet 101. The anti-pinch device 400 issues a first signal after detecting a foreign object in the first mating gap 102. This prevents foreign objects from being trapped between the air guiding plate 210 and the edge of the air outlet 101.

[0092] The air outlet 101 is located on the front surface of the housing 100. The air guiding component 200 includes an air guiding plate 210 extending vertically along its length. First mating gaps 102 are defined between the left edge of the air guiding plate 210 and the left edge of the air outlet 101, and between the right edge of the air guiding plate 210 and the right edge of the air outlet 101, respectively. The anti-pinch device 400 issues a first signal after detecting a foreign object in at least one of the first mating gaps 102. This prevents foreign objects from being clamped between the edge of the air outlet 101 and the left and right edges of the air guiding plate 210.

[0093] The air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side. The anti-pinch device 400 is also used to detect whether there is a foreign object between the first air guide plate 211 and the second air guide plate 212, and to issue a second signal when a foreign object is detected between the first air guide plate 211 and the second air guide plate 212. After receiving the second signal, the control device 500 controls the drive device 300 to drive at least one of the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object. This can prevent foreign objects from being stuck between the first air guide plate 211 and the second air guide plate 212.

[0094] The first air guide plate 211 extends along its length, and the second air guide plate 212 extends along its length, defining a second mating gap 103. The anti-pinch device 400 issues a second signal after detecting a foreign object in the second mating gap 103. This prevents foreign objects from being trapped in the second mating gap 103.

[0095] The air guide plate 210 includes a first air guide plate 211 and a second air guide plate 212 arranged side by side. A second mating gap 103 exists between the first air guide plate 211 and the second air guide plate 212. When the anti-pinch device 400 detects a foreign object in the second mating gap 103, it sends a second signal to the control device 500. Upon receiving the second signal, the control device 500 controls the drive device 300 to drive the first air guide plate 211 and the second air guide plate 212 to move away from the foreign object, respectively. This effectively prevents foreign objects from being trapped between the first air guide plate 211 and the second air guide plate 212.

[0096] The anti-pinch device 400 is an infrared detection device, comprising an infrared emitting module 470 and an infrared receiving module 480. The infrared emitting module 470 is located at the upper end of the air outlet 101 and is used to emit infrared signals. The infrared receiving module 480 is located at the lower end of the air outlet 101 and is used to receive infrared information. When the infrared signal received by the infrared receiving module 480 changes, the anti-pinch device 400 sends a signal. This allows the infrared detection device to detect the presence of foreign objects. When the infrared signal received by the infrared receiving module 480 changes, it indicates the presence of a foreign object, and the anti-pinch device 400 sends a first signal or a second signal to the control device 500.
