[0002] The intelligent human sensor commonly used in air conditioners includes an infrared imaging sensor, a radar sensor and a visible light camera. These sensors all have their own field of view (FOV) and cannot reach a detection range of 180 degrees, generally only about 90°. This means that if the air conditioner is installed in a corner of a room, the detection range of the sensor may be limited to only 45°, which cannot meet the demand of covering the entire house.

Through calculation, it can be found that if the height of the human body is 1.7 meters, at a height of 1.7 meters, the recognition area of the sensor accounts for less than 70%, which leads to a large blind area and cannot effectively cover the entire room.
[0004] The prior art provides an adjustable human sensor, for example, the scheme disclosed in the Chinese utility model patent (CN213778102U): "comprising: a positioning plate; a human sensor fixed on the surface of the positioning plate; and an adjustment knob fixed to the first side edge of the positioning plate, configured to rotate under the action of an external force to drive the positioning plate to rotate around the rotation axis of the adjustment knob to a specified angle, thereby adjusting the orientation angle of the human sensor."

[0061] The disclosure below provides many different embodiments or examples for implementing different structures of the present application.

[0062] In the prior art, the rotation of the human sensing sensor is limited to a specific axis, and the rotation flexibility is poor; at the same time, the shape of the plate-shaped component will limit the installation and use in a narrow space, and the knob arranged at the edge will also produce local stress concentration under stress, and the fracture will easily occur after the material ages.
[0063] As Figures 1 to 13 shown, a first aspect of the present application designs and provides a sensing module 100.
[0064] In one or more embodiments of the present application, the sensing module 100 includes at least one human sensing sensor 102. The human sensing sensor 102 is used to detect the presence or movement of a person in a target area.
[0065] In one or more embodiments of the present application, the human sensing sensor 102 is an infrared sensor.
[0066] The infrared sensor can sense the infrared radiation (heat) emitted by the human body or the reflected infrared light. When a person enters or moves in the detection area, the infrared sensor will detect the change of the infrared radiation or the change of the reflected light, thereby triggering the corresponding signal to realize the detection of the presence or movement of the person. The infrared sensor includes but is not limited to one or more thermoelectric pile sensors, pyroelectric sensors, or a combination of thermoelectric pile sensors and pyroelectric sensors.
[0067] In one or more embodiments of the present application, the human sensing sensor 102 is a radar sensor.
[0068] The radar sensor measures the distance, speed and direction of the target by emitting electromagnetic waves and receiving the reflected signals. When a person enters or moves in the detection area, the radar sensor will detect the change of the reflected signal to determine the position and movement state of the target, thereby realizing the detection of the presence or movement of the person.
[0069] In one or more embodiments of the present application, the human sensing sensor 102 is a combination of an infrared sensor and a radar sensor.
[0070] In one or more embodiments of the present application, a plurality of human sensing sensors 102 form a detection module.
[0071] In one or more embodiments of the present application, in addition to the sensor itself, the detection module further includes hardware components such as a microcontroller, a communication module, and a power management module. The microcontroller processes data from the infrared sensor and / or the radar sensor, performs signal fusion and analysis, and generates the final detection result. The communication module is used to transmit the detection result to external devices or systems, such as smart home controllers, etc. The power management module provides stable power supply for the sensor and the microcontroller. The microcontroller can be a single-chip microcomputer, a microprocessor, or an embedded system, and the communication module can be a wired communication module (such as RS-232, RS-485, and Ethernet) or a wireless communication module (such as Wi-Fi, Bluetooth, Zigbee, etc.). The detection module can be selected from commercially available products or known detection modules in the prior art, and the signal fusion and analysis principle thereof is not the focus of protection of the present application, and will not be described here.
[0072] In one or more embodiments of the present application, the sensing module 100 further includes a support portion 104 for supporting the human sensing sensor 102 to maintain a detection state. More specifically, the support portion 104 can ensure that the human sensing sensor 102 remains stable during use, avoiding changes in the installation position due to vibration, shaking, or other external interference, thereby affecting the detection accuracy.
[0073] In one or more embodiments of the present application, the support portion 104 is cooperatively arranged with a mounting portion 106 for mounting the support portion 104 at a predetermined position. The mounting portion 106 is provided with an opening 110 allowing the support portion 104 to extend out.
[0074] In one or more embodiments of the present application, the support portion 104 includes an operating element 108. The operating element 108 includes a spherical surface 124.
[0075] In one or more embodiments of the present application, the spherical surface 124 can be a substantially hemispherical surface 124, or a partial spherical surface 124 with a coverage range greater than or slightly greater than the hemispherical surface 124.
[0076] In one or more embodiments of the present application, the spherical surface 124 is provided with a detection window 126, and a portion (such as a probe head) of the human sensing sensor 102 extends out of the detection window 126 to achieve detection.
[0077] In one or more embodiments of the present application, the operating element 108 is operable to rotate in the opening 110 of the mounting element to adjust the detection range of the human sensing sensor 102.
[0078] By rotating the operation element 108, the user or installer can manually adjust the detection angle of the human sensing sensor 102, so that the detection angle of the human sensing sensor 102 covers most of the range of the room. The design of the spherical surface 124 allows the user to adjust the detection angle of the human sensing sensor 102 from multiple angles and directions, on the one hand, so that the human sensing sensor 102 can be uniformly rotated in multiple directions and will not be hindered due to different directions; on the other hand, the spherical surface 124 itself is a force carrier that can uniformly disperse pressure when under stress, so even if the material ages over time, it is not easy to be damaged; the operation element 108 of the spherical surface 124 is more compact and seamless between the opening 110 of the mounting element, so that the space can be more efficiently utilized and more in line with the ergonomic principle, suitable for different product industrial design styles.
[0079] In order to adapt to the needs of high installation, in addition to the operation element 108, the support part 104 also includes a retaining element 112.
[0080] In one or more embodiments of the present application, the retaining element 112 is arranged in the operation element 108. The retaining element 112 is used to support the human sensing sensor 102 to maintain a downwardly inclined detection state (inclination angle). The operation element 108 is operable to rotate in the horizontal direction in the opening 110 to adjust the detection range of the human sensing sensor 102.
[0081] The combined design of the retaining element 112 and the spherical surface 124 makes the installation and adjustment of the sensing module 100 installed at a high place more convenient. The spherical surface 124 allows flexible adjustment in the horizontal direction to cover different detection areas, adapt to various installation environments and needs, and the retaining element 112 ensures the stability of the inclination angle of the human sensing sensor 102 during adjustment, avoiding changes in the inclination angle caused by adjustment.
[0082] In one or more embodiments of the present application, the retaining element 112 includes an inclined support surface and a connecting part arranged on both sides of the support surface. The connecting part and the support surface are preferably integrally formed, and the connecting part can be detachably fixedly connected with the detection module, for example, detachably fixedly connected with the substrate of the detection module.
[0083] In one or more embodiments of the present application, the sensing module 100 can detect the current position after manual adjustment. Specifically, the support part 104 further includes a positioning element arranged along the axis direction of the spherical surface 124.
[0084] In one or more embodiments of the present application, the positioning element is one or more dials 114. The dial 114 extends upward along the axis of the spherical surface 124 of the operating element 108.
[0085] In one or more embodiments of the present application, the positioning element is integrally formed with the support portion 104.
[0086] In one or more embodiments of the present application, the sensing module 100 further comprises a detection portion. The detection portion comprises a rotary dial switch 116. The rotary dial switch 116 comprises a plurality of sets of contacts. The positioning element rotates as the operating element 108 rotates, further driving the rotary dial switch 116 to rotate. When the rotary dial switch 116 rotates, the on-off state of the plurality of sets of contacts inside the rotary dial switch 116 changes, generating a position encoding signal. After obtaining the encoding signal, the specific position of the operating element 108 after rotation, i.e., the specific position of the human sensing sensor 102, can be known.
[0087] Corresponding to the dial 114, in one or more embodiments of the present application, the rotary dial switch 116 is arranged above the operating element 108.
[0088] In one or more embodiments of the present application, the spherical surface 124 is provided with an indication area, which comprises a plurality of touch protrusions 122 to indicate the rotation position of the operating element 108.
[0089] In one or more embodiments of the present application, the touch protrusions 122 are sequentially arranged in the horizontal direction.
[0090] By providing the indication area and the touch protrusions 122, the adjustment operation is more convenient. By providing tactile feedback, on the one hand, it plays a role in preventing slipping, and on the other hand, it can help users or operators to accurately position and perform adjustment operations in low-light environments, especially when the installation environment has poor lighting conditions, which can effectively improve the adjustment efficiency. The touch protrusions 122 will not affect the industrial design of the product appearance, providing more design space.
[0091] In one or more embodiments of the present application, the support portion 104 further comprises a limiting element 118. The limiting element 118 is arranged along the axis direction of the spherical surface 124.
[0092] In one or more embodiments of the present application, the limiting element 118 is arranged along the axis direction of the spherical surface 124 and is located below the spherical surface 124.
[0093] In one or more embodiments of the present application, the mounting portion 106 further comprises a plurality of limiting openings 120, and the limiting element 118 passes through any one of the limiting openings 120 to keep the operating element 108 at a corresponding rotation position.
[0094] In one or more embodiments of this application, the limiting opening 120 is a limiting through hole, and the limiting element 118 is a limiting post.
[0095] In one or more embodiments of this application, a plurality of limiting openings 120 are distributed sequentially along the horizontal direction.
[0096] The limiting opening 120 and the limiting element 118 keep the operating element 108 in the corresponding rotation position during adjustment, ensuring that the operating element 108 stays stably in the predetermined position, preventing accidental movement or misoperation, providing clear position feedback, and helping users or operators to make accurate adjustments.
[0097] In one or more embodiments of this application, one or more of the limiting openings 120 have expanding edges. The expanding edges are used to guide the limiting element 118 to move into the limiting opening 120.
[0098] By expanding the edge, the limiting element 118 can be helped and guided into the limiting opening 120 and smoothly slide into the predetermined position. After sliding into the predetermined position, a "click" sound will be emitted due to contact, providing auditory feedback to ensure correct assembly and improve the overall adjustment efficiency and accuracy.
[0099] In one or more embodiments of this application, the sensing module 100 further includes a housing 128. The housing 128 and the mounting portion 106 are detachably fixedly connected.
[0100] The independent housing 128 effectively prevents dust, moisture, and other external substances from entering the sensor module 100, protecting the internal electronic components from damage. It also provides physical protection, absorbing external shocks and vibrations. Furthermore, the modular design allows users to configure different functions according to their needs, such as setting different numbers of sensors, improving the flexibility and adaptability of the sensor module 100. When an infrared sensor is used as the human sensor 102, the protective housing 128 ensures stable operating temperature, which is beneficial for temperature measurement.
[0101] In one or more embodiments of this application, the sensing module 100 provides three predetermined adjustment positions in the horizontal direction, such as... Figure 12 As shown, the haptic protrusions are positioned to the left, center, and right. Correspondingly, three haptic protrusions 122 are provided, including a haptic protrusion 122 on the left, a haptic protrusion 122 in the center, and a haptic protrusion 122 on the right. Similarly, three limiting openings 120 are provided, including a limiting opening 120 on the left, a limiting opening 120 in the center, and a limiting opening 120 on the right.
[0102] When the operating element 108 is rotated, the rotary dial switch 116 is linked to rotate, thereby generating a corresponding code signal. For example, when in the central position, corresponding to the "0" gear of the rotary dial switch 116, the output code signal is "0000"; when in the left position, corresponding to the "1" gear of the rotary dial switch 116, the output code signal is "0001"; when in the right position, corresponding to the "9" gear of the rotary dial switch 116, the output code signal is "1001".
[0103] Another aspect of the present application is designed and provides a sensing module, which aims to avoid the rotation of the sensor and the change of the field of view direction when the user uses a soft cloth or a slightly wet towel to wipe the air supply panel, thereby affecting the use effect of the human sensing module. The sensing module includes a human sensing sensor, which is used to detect the presence or movement of a person in a target area. The principle and use of the human sensing sensor are described in detail in the above embodiment, which will not be repeated here.
[0104] As shown in Figures 14 to 19 , the sensing module includes a support part 104. The support part 104 is used to support the human sensing sensor to maintain the detection state.
[0105] The support part 104 includes an operating element 108, which is provided with a spherical surface 124 and a locking unit 130. The spherical surface 124 is provided with a detection window 126, and the human sensing sensor detects through the detection window 126; that is, through the detection window 126, the human sensing sensor can receive external signals, thereby realizing the detection of the presence or movement of the human body. The locking unit 130 is provided with a first positioning hole 132.
[0106] The sensing module further includes a mounting part 106. The mounting part 106 is provided with an opening 110 and a second positioning hole 134. The opening 110 allows the support part 104 to extend therefrom, and the second positioning hole 134 cooperates with the first positioning hole 132.
[0107] The sensing module further includes a fixing element 136. The fixing element 136 is independently provided with the support part 104 and the mounting part 106.
[0108] The operating element 108 is operable to rotate in the opening 110 to adjust the detection range of the human sensing sensor. When the operating element 108 is rotated to a target position, the fixing element 136 extends into the corresponding first positioning hole 132 and second positioning hole 134, thereby locking the relative position of the operating element 108 and the mounting part 106.
[0109] In the positioning mode relative to the limiting hole and the limiting column, the fixing element 136 can lock the operating element 108 at the target position, and cannot be easily moved or rotated, and remains stable at the target position; in this way, even if the user uses a soft cloth or a slightly wet towel to wipe the air supply panel and accidentally touches the spherical surface 124, the sensor rotation will not cause the field of view to change.
[0110] In some embodiments of the present application, the operating element 108 has a support shaft 138. The end of the support shaft 138 is fixed on the mounting portion 106, and defines the degree of freedom of the operating element 108, so that the operating element 108 only rotates in the horizontal direction. As shown in the drawings, in some embodiments of the present application, the positioning element, i.e., the paddle 114, is fixedly arranged in the end of the support shaft 138 and extends upward along the axis of the spherical surface 124 of the operating element 108. The rotary dial switch is further located above the paddle 114, and as the operating element 108 rotates, the paddle 114 also rotates, and when the paddle 114 rotates to different positions, it further changes the on-off state of multiple groups of contacts inside the rotary dial switch, generating a position encoding signal. After obtaining the position encoding signal, the position of the operating element 108 after rotation, i.e., the field of view position of the human sensing sensor, can be detected. The rotary dial switch is a commercially available product, and the principle and internal circuit of the rotary dial switch are not further limited here. Figure 14
[0111] In some embodiments of the present application, the locking unit 130 is plate-shaped, and the locking unit 130 extends in a direction perpendicular to the support shaft 138 and away from the detection window 126.
[0112] In some embodiments of the present application, the mounting portion 106 includes a limiting end plate 140. The limiting end plate 140 extends in a direction perpendicular to the opening 110 and away from the opening 110. The limiting end plate 140 is located below the locking unit 130, and a plurality of second positioning holes 134 are arranged on the limiting end plate 140 in the rotation direction of the operating element 108; for example, one second positioning hole 134 is arranged for each of the left position, the middle position, and the right position.
[0113] The fixing element 136 extends from below into one of the second positioning holes 134 and the first positioning hole 132, locking the relative position of the operating element 108 and the mounting portion 106.
[0114] The design of the plurality of second positioning holes 134 allows the operating element 108 to be locked at multiple target positions, adapting to different use requirements. The locking unit 130 and the limiting end plate 140 are designed to be compactly overlapped, optimizing the use of space and making the overall structure of the sensing module more compact. The downward extension design facilitates the installation and removal of the fixing element 136.
[0115] In one or more embodiments of the present application, the fixing element 136 can be a screw.
[0116] In one or more embodiments of the present application, the fixing element 136 can be a sheet metal part.
[0117] In one or more embodiments of the present application, the fixing element 136 can be a positioning pin. Specifically, the fixing element 136 is cylindrical. As shown, the fixing element 136 includes a handle portion 142 for hand holding. The fixing element 136 also includes two connecting end portions 144 and two guide tips 148 formed at the tail ends of the connecting end portions 144. Figure 16 The two connecting end portions 144 are symmetrically arranged at one end of the handle portion 142, and the elastic groove 146 is formed between the two connecting end portions 144. The free ends of the two connecting end portions 144, i.e., the tail ends, are respectively formed with a guide tip 148. In some embodiments of the present application, the guide tip 148 is obliquely formed at the free end of the connecting end portion 144, and the tail of the guide tip 148 has a smaller cross-sectional area. The guide tip 148 extends radially outward. The elastic groove 146 provides a certain deformation adjustment space, which can adapt to the size deviation of the first positioning hole 132 and the second positioning hole 134, so that the insertion and extraction are more smooth; the design of the guide tip 148 can reduce the resistance and friction during the insertion and extraction, so that the locking process is more accurate, and the radial design can lock the locking unit 130 and the limiting end plate 140 after the guide tip 148 passes through the first positioning hole 132.
[0118] In one or more embodiments of the present application, the connecting end portion 144 can also be provided with four or more.
[0119] In order to realize integrated design, the microcontroller, communication module, power management module and other hardware in the detection module are all arranged on the substrate 150. The substrate 150 is a PCB circuit board, which can provide a stable mechanical support structure for fixing and protecting the hardware circuit and realizing stable electrical connection. The substrate 150 is arranged above the support shaft 138 along the horizontal direction, and also serves to support the rotary dial switch, so as to ensure that only one circuit board is arranged in the entire sensing module, significantly reducing the complexity of the circuit, effectively utilizing the space, and reducing the volume and weight of the detection module.
[0120]
[0121] The following describes the holding element 112 provided in some embodiments of the present application. The holding element 112 is arranged in the operating element 108 to support the human sensing sensor to maintain the sensing element 152 in a downwardly inclined detection state. The holding element 112 can be an injection molded part or a sheet metal part. The holding element 112 predefines the inclination angle of the sensing element 152, so that the sensing element 152 is more likely to capture the human infrared radiation located below or in front of the sensing element 152.
[0122] Taking the infrared sensor as an example of the human sensing sensor, the sensing element 152 of the human sensing sensor is encapsulated in a small metal or plastic hard shell to protect the internal core elements (such as thermocouples and circuits). In addition to the sensing element 152, the human sensing sensor also includes a light transmission lens 154, which is used to focus infrared radiation and guide human infrared radiation to the sensing element 152. The light transmission lens 154 can be made of hard transparent material, such as glass. The light transmission lens 154 can include a Fresnel lens or a convex lens.
[0123] Corresponding to the light transmission lens 154 and the sensing element 152, the operating element 108 is also configured with a first clamping groove 160 and a second clamping groove 162. The light transmission lens 154 is located in the first clamping groove 160, and the second clamping groove 162 is in communication with the first clamping groove 160, and the sensing element 152 is located in the second clamping groove 162 corresponding to the light transmission lens 154 and maintaining a downwardly inclined state. The first clamping groove 160 and the second clamping groove 162 provide a stable support structure to ensure that the light transmission lens 154 and the sensing element 152 maintain a fixed position and angle during use, avoiding positional deviation caused by vibration or external force.
[0124] Since the light transmission lens 154 and the sensing element 152 are of comparable size, the gap between the light transmission lens 154 and the sensing element 152 is very small, and the operating space inside the operating element 108 is very compact, and at the same time, the ejection angle of the injection molded part can also cause the internal structure of the operating element 108 to be irregular or asymmetric, which makes it impossible for the light transmission lens 154 to limit the sensing element 152 through the rotating spherical surface 124 after installation. To solve this problem, the holding element includes a holding element body 156, which covers the outside of the sensing element 152, and the holding element body 156 is at least partially located between the first clamping groove 160 and the sensing element 152 to support the human sensing sensor to maintain the sensing element 152 in a downwardly inclined detection state.
[0125] As Figure 19As shown, during installation, the holding element body 156 is first covered outside the packaged sensing element 152, and the holding element body 156 is positioned against the sensing element 152 in the negative direction of the X-axis, Y-axis and Z-axis, thereby restricting five degrees of freedom. Then, the integrated holding element and packaged sensing element 152 are arranged in the operating element 108, and the upper and lower parts of the holding element body 156 are respectively located between the second clamping groove 162 and the sensing element 152, thereby achieving the positive direction of the Z-axis. The sensing element 152 of the human sensor is kept in a downwardly inclined detection state. The positions of the upper and lower parts of the second clamping groove 162 in the figure are A and B, respectively, which define the positions of the holding element body 156.
[0126] The holding element 112 further comprises a connecting plate 158 located on both sides of the holding element body 156. The holding element body 156 is arranged obliquely relative to the connecting plate 158, and the connecting plate 158 is fixedly connected with the operating element 108; for example, the shaft hole on the connecting plate 158 is guided, and after being installed in place, it is fixed in the form of hot melting; ensuring that the sensing element 152 is still positionally stable under the condition of long time and multiple rotations.
[0127] The second aspect of the present application provides an air conditioning device. The air conditioning device comprises an indoor unit. The indoor unit has an air supply port for supplying treated air into a room. The indoor unit has a panel 200, and the air supply port is arranged on the panel 200. An installation opening 202 is also formed in the panel 200.
[0128] The indoor unit further comprises a sensing module 100. The specific structure of the sensing module 100 is described in detail in the above embodiments and the accompanying drawings, and will not be repeated here.
[0129] The operating element extends outwardly from the installation opening 202.
[0130] In one or more embodiments of the present application, the air conditioning device can be an air conditioner.
[0131] The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling element and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and performs refrigeration or heating for an indoor space.
[0132] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
[0133] The throttling element (for example, an electronic expansion valve) expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the electronic expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of an indoor space.
[0134] The outdoor unit of the air conditioner refers to a portion of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the electronic expansion valve can be provided in the indoor unit or the outdoor unit.
[0135] The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in a heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in a cooling mode.
[0136] In one or more embodiments of the present application, the air conditioning apparatus can be a fresh air device. The fresh air device includes a filter and a fan for removing particulate matter and harmful gases in the air while introducing fresh air to maintain indoor air freshness. The fresh air device can be a separate device or can be integrated in the air conditioner as a functional module of the air conditioner.
[0137] In one or more embodiments of the present application, the air conditioning apparatus can be an air purifier.
[0138] The air purifier is a device for improving indoor air quality by removing particulate matter, gaseous pollutants, and harmful substances in the air, as well as eliminating odors and killing bacteria, and the like, to make the air fresher and healthier.
[0139] A filter system for removing particulate matter in the air can be provided in the air purifier. The filter system can be a HEPA (High Efficiency Particulate Air Filter), an activated carbon filter, or the like.
[0140] An ultraviolet lamp for killing bacteria, viruses, and other microorganisms in the air can also be provided in the air purifier.
[0141] An ion generator that allows particulate matter in the air to be charged and easily captured by a filter can also be provided in the air purifier.
[0142] In one or more embodiments of the present application, the air conditioning apparatus can be a total heat exchanger.
[0143] The total heat exchanger can transfer heat between the incoming air and the exhaust air, achieve energy recovery, pre-adjust the temperature of the fresh air entering the building, reduce the energy required for heating or air conditioning, reduce energy consumption, and save energy expenditure. The total heat exchanger can also adjust humidity under appropriate circumstances, helping to maintain the comfort and quality of indoor air.
[0144] In one or more embodiments of the present application, the air conditioning device can be a dehumidifier.
[0145] In one or more embodiments of the present application, the air conditioning device can be a humidifier.
[0146] In one or more embodiments of the present application, the air conditioning device can be an air circulation fan.
[0147] The air circulation fan is used to promote air flow, helping to evenly distribute pollutants and temperature in the air.
[0148] In one or more embodiments of the present application, the air conditioning device can also be a combination of multiple air conditioners, fresh air equipment, air purifiers, total heat exchangers, dehumidifiers, humidifiers, and air circulation fans.
[0149] In one or more embodiments of the present application, the mounting portion 106 is detachably fixedly arranged inside the panel 200.
[0150] The detachable design allows the sensing module 100 to be easily detached from the inside of the panel 200, allowing modular maintenance, while simplifying the installation process and improving user experience.
[0151] In one or more embodiments of the present application, the adjustable range of the operating element rotating in the horizontal direction in the mounting opening 202 is not less than 20 degrees. Figures 20 to 23 It is shown that the detection range at a height of 1.7 meters and the ground level is significantly reduced when rotated by 20 degrees; when rotated by 40 degrees, there is basically no blind area. In this way, even if the indoor unit is installed in a corner position, the adjusted area can still cover most of the area of the room, providing accurate detection results. The air conditioning device can compensate for the location of the detected object according to the adjusted position, so that the air outlet can correctly blow air or avoid blowing action on the target.
