Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a sensor assembly and an air conditioner having the same. Background Technology

[0002] Air conditioners are part of indoor air circulation systems. As living standards continue to improve, people have increasingly higher requirements for indoor air quality. Air conditioners with health functions (such as adding fresh air systems and air purification systems) are gradually entering people's daily lives. During use, these air conditioners can detect and regulate indoor air quality, keeping the indoor CO2 (carbon dioxide) concentration at a comfortable level for the human body, thereby protecting the user's health.

[0003] However, existing air conditioners suffer from poor CO2 sensor detection accuracy. Summary of the Invention

[0004] The first objective of this invention is to provide a sensor assembly to solve the technical problem of poor CO2 sensor detection accuracy in existing air conditioners.

[0005] The sensor assembly provided by this invention includes an air detection sensor and a mounting box. The mounting box is configured to connect to the frame of an indoor air conditioner unit and forms a mounting cavity. The air detection sensor is fixedly disposed in the mounting cavity. The mounting cavity has opposing and spaced-apart air inlet walls and air outlet walls. The air inlet wall has an air guide hole, and the air outlet wall has a vent hole. The air guide hole is configured to guide air entering from the air inlet of the indoor air conditioner unit to the mounting cavity, and the vent hole is configured to allow air to flow out of the mounting cavity. The detection chip of the air detection sensor faces the vent hole, and along a set direction, the detection area of ​​the detection chip completely covers the vent hole, and the area of ​​the detection area is larger than the area of ​​the vent hole. The set direction is from the air inlet wall to the air outlet wall.

[0006] Taking a CO2 sensor as an example, the following explanation illustrates how air can be detected using an air quality sensor. When the air conditioner uses the aforementioned sensor assembly, air enters through the air inlet of the indoor unit during operation and flows into the mounting cavity via the air guide hole. As the air flows over the surface of the detection chip, flow detection is achieved. Meanwhile, the air in the mounting cavity can be exhausted through the vent. By utilizing the continuous flow of air through the air inlet, air guide hole, and vent, real-time detection of indoor CO2 levels is achieved.

[0007] In this sensor assembly, by setting the detection area of ​​the CO2 sensor's detection chip to completely cover the vent hole and setting the area of ​​the detection area to be larger than the area of ​​the vent hole, on the one hand, the air in the mounting cavity can flow through the detection area before being discharged through the vent hole, preventing the situation where air entering through the air guide hole is discharged directly through the vent hole without being detected, thus ensuring the reliability of the detected sample and improving the detection accuracy. On the other hand, this setting also allows the air to fully contact the detection area before being discharged through the vent hole, thereby further improving the detection accuracy.

[0008] Furthermore, the air guide hole includes a main air hole, which is positioned in a direction opposite to the predetermined direction. The mounting box forms a projection of the box body on the frame, and the main air hole is located near the edge of the projection of the box body. By placing the main air hole near the edge of the projection of the box body, the airflow path within the mounting box can be effectively shortened, air resistance reduced, and airflow enhanced, thereby further ensuring detection accuracy.

[0009] Furthermore, the surface of the air inlet wall facing away from the air outlet wall is provided with a wind-blocking protrusion. This wind-blocking protrusion has an air inlet guiding surface configured to guide air entering through the air inlet to the main air vent. By providing the wind-blocking protrusion with the air inlet guiding surface, airflow near the main air vent can be diverted, allowing this air to smoothly enter the mounting cavity, thereby increasing the airflow into the mounting cavity and ensuring detection effectiveness.

[0010] Furthermore, the air guide hole also includes an auxiliary air guide hole, which is located between the air inlet and the main air guide hole. This arrangement serves two purposes: firstly, the airflow entering through the auxiliary air guide hole will disturb the airflow entering through the main air guide hole, thereby creating a turbulent airflow into the mounting cavity, improving air uniformity and further enhancing the detection accuracy of the air sensor; secondly, it can also balance the air pressure in the mounting cavity, reducing or even eliminating airflow noise.

[0011] Furthermore, the outlet end of the vent is provided with an air outlet guide surface, which extends obliquely away from the center of the vent along the predetermined direction. This arrangement allows the airflow to be scattered and discharged, thereby slowing down the airflow through the detection chip and facilitating detection.

[0012] Furthermore, the total area of ​​the vent holes in the air outlet wall is 30% to 60% of the area of ​​the detection area; this design not only ensures that all air flows through the detection area before being discharged through the vent holes, but also avoids excessively increasing airflow resistance, making the airflow through the vent holes smoother. And / or, the total area of ​​the air guide holes in the air inlet wall is 50% to 70% of the total area of ​​the vent holes in the air outlet wall; this design facilitates airflow within the mounting cavity, thereby ensuring detection effectiveness. And / or, the vent holes have a grid structure, which ensures the structural strength of the mounting box with the same vent hole area.

[0013] Furthermore, the mounting box has an opening, and the mounting box is fixedly connected to the frame with the opening facing the frame. The mounting box and the frame together form the mounting cavity, wherein the air guide hole is opened in the frame, and the ventilation hole is opened in the mounting box. This design, while constructing the mounting cavity, also reduces the material used in the mounting box, saving material costs.

[0014] Furthermore, a sealing rib is provided between the edge of the opening and the frame, and the sealing rib is configured to close the gap between the mounting box and the frame. This feature achieves waterproofing and dustproofing, thereby further ensuring detection accuracy.

[0015] Furthermore, the sealing rib is fixedly disposed at the edge of the opening, and the frame has a groove, the shape and position of which correspond to the shape and position of the sealing rib, and the sealing rib is embedded in the groove. This arrangement not only effectively seals the gap between the mounting box and the frame, but also uses the groove to limit the installation of the sealing box, preventing it from moving on the frame surface.

[0016] Furthermore, the air detection sensor is detachably mounted to the mounting box, which in turn is detachably mounted to the frame. This design facilitates the disassembly and maintenance of the air detection sensor, improving maintenance convenience.

[0017] Furthermore, the side wall of the mounting box is provided with snap-fit ​​holes, and the frame is provided with first buckles corresponding to the snap-fit ​​holes. The snap-fit ​​holes engage with the first buckles. The first buckle includes a buckle component and a base. The base includes an L-shaped connecting section and a supporting section. The connecting section is fixedly connected to the frame, and the supporting section is spaced apart from the frame. The buckle component is fixedly disposed on the side of the supporting section facing away from the frame. This design not only enables a detachable and fixed connection between the mounting box and the frame, but also gives the first buckle a certain degree of elasticity. During assembly, the first buckle swings due to elastic deformation, enabling quick assembly and disassembly of the mounting box, saving time and effort.

[0018] Furthermore, the snap-fit ​​component is provided with a guide slope, which is configured to guide the snap-fit ​​hole into the snap-fit ​​component. By providing a guide slope to the snap-fit ​​component, the efficiency of the snap-fit ​​hole engaging with the snap-fit ​​component can be improved, thereby improving the assembly efficiency of the mounting box. And / or, the first snap-fit ​​also includes several reinforcing ribs, which connect the connecting section and the supporting section, and connect the snap-fit ​​component and the supporting section. The reinforcing ribs can provide a certain structural reinforcement to the first snap-fit, reducing the risk of damage to the first snap-fit ​​due to repeated bending. And / or, the first snap-fit ​​also includes a button, which is fixedly disposed at the end of the snap-fit ​​component away from the supporting section. This arrangement can provide an effective force application point for the snap-fit ​​component, making it convenient for the user to apply force to the snap-fit ​​component. And / or, the side of the bearing section facing away from the frame is provided with a protrusion; by providing the protrusion, on the one hand, it can play a certain limiting and supporting role for the mounting box after the mounting box is assembled in place, and on the other hand, it can increase the structural strength of the bearing section and reduce the risk of damage to the bearing section during long-term use.

[0019] Furthermore, the mounting box contains multiple second snap-fits arranged at intervals along its contour edge. The air detection sensor is secured to the mounting box by these snap-fits. This design is not only simple in structure but also facilitates quick assembly and disassembly of the air detection sensor. Alternatively, the mounting box contains a positioning post, and the air detection sensor has a positioning hole that engages with the positioning post. This design enables positioning of the air detection sensor during assembly, ensuring its installation accuracy and consequently its detection accuracy. Or, the mounting box also contains an abutment portion configured to abut against the air detection sensor after it has been assembled with the mounting box. This abutment portion provides support for the air detection sensor, ensuring its installation stability.

[0020] Furthermore, the side wall of the mounting box has a wire-through hole, which is configured to allow the electrical connection wire of the air detection sensor to pass through. The air detection sensor includes a plug-in terminal, and the electrical connection wire is connected to the plug-in terminal. An anti-detachment rib is fixedly provided inside the mounting box. In the assembled state of the air detection sensor and the mounting box, the anti-detachment rib is located between the detection chip and the wire-through hole, and the anti-detachment rib is used to cooperate with the plug-in terminal. This arrangement not only realizes the connection between the air detection sensor and the controller, but also uses the anti-detachment rib to block the plug-in terminal, thereby achieving the purpose of preventing the plug-in terminal from detaching and ensuring the reliability of the electrical connection between the detection chip and the controller. And / or, the side wall of the mounting box has a wire-through hole, which is configured to allow the electrical connection wire of the air detection sensor to pass through. The wire-through hole is an open hole, and an eagle-beak bracket is provided at the open part of the wire-through hole. The eagle-beak bracket is configured to prevent the electrical connection wire from falling out of the open part. With this setting, on the one hand, the electrical connection wire can be smoothly routed without having to pass the electrical connection wire from one end of the wire-through hole to the other, thus improving the routing efficiency. On the other hand, it can also limit the electrical connection wire to a certain extent, preventing the electrical connection wire from falling out of the wire-through hole without external force.

[0021] Furthermore, the frame is provided with a wiring channel configured to accommodate the electrical connection wire of the air detection sensor. This arrangement not only prevents the wire from being damaged by other components in the indoor unit of the air conditioner, but also ensures the neatness of the wiring and prevents it from becoming tangled with other components. Alternatively, the frame is fixedly provided with wire clamps configured to secure the electrical connection wire to the frame. These clamps effectively secure the wire within the wiring channel, preventing it from accidentally falling out.

[0022] The second objective of this invention is to provide an air conditioner that solves the technical problem of poor CO2 sensor detection accuracy in existing air conditioners.

[0023] The air conditioner provided by the present invention includes an indoor unit and an outdoor unit connected to the piping of the indoor unit, wherein the indoor unit is provided with the aforementioned sensor assembly.

[0024] By incorporating the aforementioned sensor assembly into the air conditioner, the air conditioner acquires all the advantages of the aforementioned sensor assembly, which will not be elaborated upon here.

[0025] Furthermore, the indoor unit of the air conditioner is a wall-mounted air conditioner, and the middle frame of the wall-mounted air conditioner forms the frame. This configuration enables the wall-mounted air conditioner to detect indoor CO2 concentration. Attached Figure Description

Detailed Implementation

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] Figure 1 This is an exploded view of the structure of the indoor unit of the air conditioner provided in this embodiment. Figure 2 This is a schematic diagram showing the installation of the sensor assembly on the frame 300 according to this embodiment. Figure 3 A cross-sectional view of the sensor assembly provided in this embodiment mounted on the frame 300. Figure 1 .like Figures 1 to 3As shown, this embodiment provides an air conditioner, including an indoor unit and an outdoor unit connected to the indoor unit via piping. The indoor unit is equipped with a sensor assembly. The sensor assembly includes an air detection sensor 100 and a mounting box 200, the mounting box 200 being configured to connect to the frame 300 of the indoor unit. Specifically, in this embodiment, the air detection sensor 100 can be a CO2 sensor.

[0047] By installing the aforementioned sensor components in the indoor unit of the air conditioner, the indoor CO2 concentration can be detected, allowing the indoor unit to adjust the indoor air quality in a timely manner based on the current detection data. This keeps the indoor CO2 concentration at a comfortable level for the human body, thus protecting the health of users.

[0048] Please continue to refer to Figure 1 In this embodiment, the indoor unit of the air conditioner is a wall-mounted air conditioner, wherein the middle frame of the wall-mounted air conditioner forms the aforementioned frame 300. This configuration enables the wall-mounted air conditioner to detect indoor CO2 concentration.

[0049] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the indoor unit of the air conditioner also includes a panel 400, and the sensor assembly is located between the panel 400 and the frame 300.

[0050] In this embodiment, only the air detection sensor 100 is used as a CO2 sensor for illustration. It is understood that in actual use, the air detection sensor 100 can also be a sensor that can detect the concentration of other substances in the air. This embodiment will not give examples of each.

[0051] Figure 4 This is a partial front view of the frame 300 of the indoor unit of the air conditioner provided in this embodiment. Please continue to refer to... Figure 2 and combined Figure 4 In this embodiment, the indoor unit of the air conditioner is equipped with a controller 600, and the air detection sensor 100 in the sensor assembly is electrically connected to the controller 600.

[0052] The method by which the air detection sensor 100 detects the concentration of gases in the air and transmits the detected data to the controller 600 for feedback adjustment of air quality is something that those skilled in the art can obtain based on existing technology. This embodiment does not improve upon this, so it will not be described in detail here.

[0053] The following text will provide a detailed description of the specific structure and principle of the sensor assembly, as well as its assembly structure with the frame 300.

[0054] Please continue to refer to Figure 3In this embodiment, after the mounting box 200 is connected to the frame 300, a mounting cavity 210 is constructed. The air detection sensor 100 is fixedly installed in the mounting cavity 210. Specifically, the mounting cavity 210 has an air inlet wall and an air outlet wall that are opposite to each other and spaced apart. The air inlet wall has an air guide hole 310, and the air outlet wall has a vent hole 220. The air guide hole 310 is configured to guide the air entering from the air inlet 320 of the indoor unit of the air conditioner to the mounting cavity 210, and the vent hole 220 is configured to allow the air in the mounting cavity 210 to flow out. The detection chip 110 of the air detection sensor 100 faces the vent hole 220. Along a set direction, the detection area of ​​the detection chip 110 completely covers the vent hole 220, and the area of ​​the detection area is larger than the area of ​​the vent hole 220. The set direction is from the air inlet wall to the air outlet wall, that is, the set direction is... Figure 3 The direction indicated by the middle arrow 'a'.

[0055] Taking the air detection sensor 100 as an example of a CO2 sensor, the following explanation is provided. When the air conditioner uses the aforementioned sensor assembly, during the operation of the indoor unit, air enters through the air inlet 320 and then flows into the mounting cavity 210 via the air guide hole 310. When the air entering the mounting cavity 210 flows over the surface of the detection chip 110, flow detection is achieved. The air in the mounting cavity 210 can then be discharged through the vent hole 220. By utilizing the continuous flow of air through the air inlet 320, air guide hole 310, and vent hole 220, real-time detection of indoor CO2 is achieved.

[0056] In this sensor assembly, by setting the detection area of ​​the CO2 sensor's detection chip 110 to completely cover the vent 220, and setting the area of ​​the detection area to be larger than the area of ​​the vent 220, on the one hand, the air in the mounting cavity 210 can flow through the detection area before being discharged through the vent 220, preventing the air entering through the air guide hole 310 from being discharged directly through the vent 220 without being detected, thus ensuring the reliability of the detected sample and improving the detection accuracy. On the other hand, this setting also allows the air to fully contact the detection area before being discharged through the vent 220, thereby further improving the detection accuracy.

[0057] In this embodiment, the total area of ​​the ventilation holes 220 provided on the air outlet wall is 30% to 60% of the area of ​​the detection area. This arrangement not only ensures that all the air can flow through the detection area before being discharged through the ventilation holes 220, but also does not excessively increase the airflow resistance, making the airflow through the ventilation holes 220 relatively smooth.

[0058] In this embodiment, the total area of ​​the vent holes 220 of the air outlet wall is greater than the total area of ​​the air guide holes 310 of the air inlet wall. Preferably, the total area of ​​the air guide holes 310 of the air inlet wall is 50% to 70% of the total area of ​​the vent holes 220 of the air outlet wall. This arrangement facilitates air circulation within the mounting cavity 210, thereby ensuring the detection effect.

[0059] Please continue to refer to Figure 3 In this embodiment, the mounting box 200 has an opening and is fixedly connected to the frame 300 with the opening facing the frame 300. The mounting box 200 and the frame 300 together form a mounting cavity 210, wherein an air guide hole 310 is formed in the frame 300 and an air vent 220 is formed in the mounting box 200. That is to say, the air inlet wall is formed by a portion of the frame 300, and the air outlet wall is formed by the box wall of the mounting box 200 opposite to its opening.

[0060] By using the above configuration, while constructing the mounting cavity 210, the material usage of the mounting box 200 can be reduced, thus saving material costs.

[0061] Please continue to refer to Figure 3 In this embodiment, the air guide hole 310 includes a main air guide hole 311. Along the direction opposite to the set direction, the mounting box 200 forms a box body projection on the frame 300, and the main air guide hole 311 is set near the edge of the box body projection.

[0062] During operation, most of the air entering the indoor unit of the air conditioner through the air inlet 320 will enter the mounting cavity 210 through the main air vent 311. After flowing through the detection area of ​​the detection chip 110 in the mounting cavity 210, it will be discharged through the vent 220. By placing the main air vent 311 near the edge of the housing projection, the airflow path within the mounting box 200 can be effectively shortened, reducing air resistance and enhancing airflow, thereby further ensuring detection accuracy.

[0063] Please continue to refer to Figure 2 In this embodiment, a wind-blocking protrusion 330 is provided on the surface of the air inlet wall facing away from the air outlet wall. That is, a wind-blocking protrusion 330 is provided on the side of the frame 300 facing away from the mounting box 200. The wind-blocking protrusion 330 is provided with an air inlet guiding surface 331, which is configured to guide the air entering from the air inlet 320 to the main air vent 311. In the operating state of the indoor unit of the air conditioner, the wind-blocking protrusion 330 is located below the main air vent 311 (for...). Figure 3 From a visual perspective, the air inlet 320 is located to the left of the main air vent 311, and the air dam 330 is located to the right of the main air vent 311.

[0064] By setting up a wind-blocking protrusion 330 with an air inlet guide surface 331, the air near the main air inlet 311 can be diverted, allowing this air to smoothly enter the mounting cavity 210, thereby increasing the airflow into the mounting cavity 210 and ensuring the detection effect. Moreover, this setting can also avoid the situation where a negative pressure zone is formed in the air inlet area, which would be detrimental to the airflow through the detection chip 110.

[0065] Please continue to refer to Figure 3 In this embodiment, the air inlet guide surface 331 is set at an angle θ with the set direction, where θ can be 60°. This large-angle air inlet guide surface 331 facilitates guiding the airflow across the surface of the detection chip 110, thereby achieving rapid detection.

[0066] Specifically, in this embodiment, the air inlet guide surface 331 is a concave arc surface. This design allows for better airflow guidance.

[0067] Figure 5 This is a rear view structural diagram of the frame 300 of the indoor unit of the air conditioner provided in this embodiment. Figure 6 for Figure 5 A magnified view of the local structure at point A. Please continue referring to this. Figure 3 and combined Figure 5 and Figure 6 In this embodiment, the air guide 310 may further include an auxiliary air guide 312. Specifically, the auxiliary air guide 312 is located between the air inlet 320 and the main air guide 311. That is, when the indoor unit of the air conditioner is in use, the auxiliary air guide 312 is located above the main air guide 311 (for...). Figure 3 From a visual perspective, the auxiliary air guide 312 is located to the left of the main air guide 311.

[0068] By setting the auxiliary air guide hole 312, on the one hand, a small portion of air will enter the mounting cavity 210 through the auxiliary air guide hole 312, and the airflow entering through the auxiliary air guide hole 312 will disturb the airflow entering through the main air guide hole 311, thereby making the airflow entering the mounting cavity 210 through the air guide hole 310 form a turbulent airflow, improving the uniformity of the air, and further improving the detection accuracy of the air detection sensor 100. On the other hand, the setting of the auxiliary air guide hole 312 can also play a role in balancing the air pressure in the mounting cavity 210, reducing or even avoiding airflow noise.

[0069] Please continue to refer to Figure 5 and Figure 6In this embodiment, there are two main air vents 311, which are strip-shaped to increase the airflow entering through them. There are three auxiliary air guides 312, which are circular. These three circular holes are spaced apart to disturb the airflow at multiple points, further improving air uniformity. The wind-blocking protrusions 330 are elongated and distributed along the extension direction of the main air vents 311, thus guiding the airflow to the main air vents 311 more effectively.

[0070] Please continue to refer to Figure 3 In this embodiment, the outlet end of the vent 220 is provided with an air outlet guide surface 221, which extends obliquely in a direction away from the center of the vent 220 along a set direction.

[0071] By setting an air outlet guide surface 221 at the outlet end of the vent 220, the air in the mounting cavity 210 can be discharged along the air outlet guide surface 221 when it is discharged through the vent 220, that is, it is discharged at an angle away from the center of the vent 220, so as to achieve the purpose of scattering the airflow. This slows down the airflow through the detection chip 110, which is beneficial for detection.

[0072] Figure 7 This is a schematic diagram of the mounting box 200 for the sensor assembly provided in this embodiment. Figure 8 This is a schematic diagram of the mounting box 200 for the sensor assembly provided in this embodiment from another perspective. Please continue to refer to... Figure 3 and combined Figure 7 and Figure 8 In this embodiment, the air outlet guide surface 221 is formed by the wall of the vent 220. This arrangement achieves the effect of scattering the airflow while reducing the space occupied by the mounting box 200, thus improving the structural compactness of the sensor assembly.

[0073] Please continue to refer to Figure 7 and Figure 8 In this embodiment, the vent 220 has a grid structure. The edge wall of the vent 220 forms an air outlet guide surface 221.

[0074] This design not only ensures an effective exhaust area, allowing air in the mounting cavity 210 to be discharged smoothly, but also helps to improve the structural strength of the mounting box 200, thereby extending the service life of the mounting box 200.

[0075] Figure 9 This is an exploded view of the sensor assembly provided in this embodiment. Figure 10 This is a schematic diagram of the assembled sensor assembly provided in this embodiment. Figure 9 and Figure 10 As shown, in this embodiment, the air detection sensor 100 is detachably mounted to the mounting box 200, and the mounting box 200 is detachably mounted to the frame 300.

[0076] The above configuration allows for easy maintenance of the air detection sensor 100. The mounting box 200, along with the air detection sensor 100, can be removed from the frame 300, and then the air detection sensor 100 can be removed from the mounting box 200. This facilitates maintenance of the air detection sensor 100, and when the air detection sensor 100 malfunctions and needs replacement, the mounting box 200 does not need to be replaced, resulting in lower maintenance costs.

[0077] Figure 11 A cross-sectional view of the sensor assembly provided in this embodiment mounted on the frame 300. Figure 2 .like Figure 11 As shown, in this embodiment, a sealing rib 230 is provided between the edge of the opening of the mounting box 200 and the frame 300, wherein the sealing rib 230 is configured to close the gap between the mounting box 200 and the frame 300.

[0078] The above settings can achieve a seal at the opening edge of the mounting box 200, preventing the water film formed on the surface of the mounting box 200 body during the cooling operation of the air conditioner from entering the mounting cavity 210 through the opening, and preventing dust from entering the mounting cavity 210 and affecting the detection accuracy.

[0079] In this embodiment, the sealing rib 230 can be made of rubber.

[0080] Please continue to refer to Figure 8 , Figure 10 and Figure 11 In this embodiment, the sealing rib 230 is fixedly disposed on the edge of the opening, and the frame 300 has a groove 340. The shape and position of the groove 340 correspond to the shape and position of the sealing rib 230, and the sealing rib 230 is embedded in the groove 340.

[0081] This design not only effectively seals the gap between the mounting box 200 and the frame 300, but also uses the groove 340 to limit the installation of the sealing box, preventing the mounting box 200 from moving on the surface of the frame 300.

[0082] In other embodiments, the sealing rib 230 may also be fixedly disposed on the frame 300.

[0083] Please continue to refer to Figures 7 to 10In this embodiment, the side wall of the mounting box 200 is provided with a pin 251 and a connecting hole, and the pin 251 and the connecting hole are spaced apart along the circumference of the mounting box 200; please continue to refer to Figure 4 The frame 300 is equipped with a limit slot 350 and a connection structure. (See also...) Figure 2 and Figure 11 The pin 251 is inserted into the limiting slot 350, and the connecting hole is connected to the connecting structure.

[0084] When it is necessary to install the sensor assembly onto the frame 300, the pin 251 can be inserted into the limiting slot 350 to pre-position the sensor assembly. Then, the connection between the connecting hole and the connecting structure can be used to fix the sensor assembly onto the frame 300.

[0085] In this embodiment, the pin 251 and the connecting hole are respectively disposed on two opposite side walls of the mounting box 200. This arrangement can prevent local warping of the mounting box 200, thereby ensuring the assembly effect of the sensor assembly and reducing the risk of it falling off.

[0086] Specifically, the pin 251 and the connecting hole are respectively located on the two short sides of the mounting box 200.

[0087] Please continue to refer to Figure 10 In this embodiment, a supporting rib 254 is connected between the pin 251 and the side wall of the mounting box 200. This arrangement can strengthen the structure of the pin 251, reduce the stress concentration at the connection between the pin 251 and the mounting box 200, and thus extend the service life of the pin 251.

[0088] Please continue to refer to Figures 7 to 10 In this embodiment, the connecting hole includes a snap-fit ​​hole 252 and a screw hole 253. Please continue to refer to... Figure 4 The connection structure includes a first snap-fit ​​360 corresponding to the snap-fit ​​hole 252 and a screw seat 370 corresponding to the screw hole 253. Specifically, the snap-fit ​​hole 252 engages with the first snap-fit ​​360, and the connecting screw 500 passes through the screw hole 253 and is screwed and fixed to the screw seat 370. After the sensor assembly is installed, as shown... Figure 2 As shown.

[0089] The above settings not only enable a detachable and fixed connection between the mounting box 200 and the frame 300, but also ensure a reliable connection, effectively reducing the risk of the mounting box 200 falling off the frame 300 and thus guaranteeing the installation stability of the sensor assembly.

[0090] Figure 12 This is a cross-sectional view of the structure of the sensor assembly mounting box 200 provided in this embodiment when it is engaged with the first snap-fit ​​360. Figure 13 for Figure 4A magnified view of the local structure at point B. (See image below.) Figure 12 and Figure 13 As shown, in this embodiment, the first buckle 360 ​​includes a buckle component 361 and a base 362. The base 362 includes an L-shaped connecting section 3621 and a supporting section 3622. Specifically, the connecting section 3621 is fixedly connected to the frame 300, the supporting section 3622 is spaced apart from the frame 300, and the buckle component 361 is fixedly disposed on the side of the supporting section 3622 facing away from the frame 300.

[0091] When it is necessary to remove the mounting box 200 from the frame 300, the threaded connection between the connecting screw 500 and the screw seat 370 can be released first. Then, the buckle component 361 can be moved to deform the first buckle 360 ​​by utilizing the gap between the bearing section 3622 and the frame 300, so that the snap hole 252 can be smoothly disengaged from the buckle component 361, thereby achieving the purpose of removing the mounting box 200.

[0092] This design gives the first buckle 360 ​​a certain degree of elasticity. During assembly, the first buckle 360 ​​deforms left and right through elastic deformation. Figure 12 The swinging motion (from the perspective of the angle) enables quick assembly and disassembly of the mounting box 200, saving time and effort. It effectively prevents the mounting box 200 from being difficult to assemble and disassemble from the frame 300, thereby improving the assembly and disassembly efficiency of the mounting box 200 and enhancing the user experience.

[0093] In this embodiment, the distance L between the bearing section 3622 and the frame 300 can be 2mm.

[0094] Please continue to refer to Figure 12 and Figure 13 In this embodiment, the snap-fit ​​component 361 is provided with a guide slope 3611, wherein the guide slope 3611 is configured to guide the snap-fit ​​hole 252 into the snap-fit ​​component 361. By providing the guide slope 3611 in the snap-fit ​​component 361, the efficiency of the snap-fit ​​hole 252 into the snap-fit ​​component 361 can be improved, thereby improving the assembly efficiency of the mounting box 200.

[0095] Please continue to refer to Figure 12 In this embodiment, the first buckle 360 ​​may further include several reinforcing ribs 363. Specifically, reinforcing ribs 363 are connected between the connecting section 3621 and the bearing section 3622, and reinforcing ribs 363 are also connected between the buckle component 361 and the bearing section 3622. The setting of reinforcing ribs 363 can play a certain structural strengthening role for the first buckle 360 ​​and reduce the risk of damage to the first buckle 360 ​​due to repeated bending.

[0096] Please continue to refer to Figure 12 and Figure 13In this embodiment, the first buckle 360 ​​may also include a button 364. Specifically, the button 364 is fixedly disposed at one end of the buckle component 361 away from the bearing section 3622. That is, the button 364 is fixedly disposed at the end of the buckle component 361 that first enters the snap hole 252.

[0097] By providing a button 364 at the end of the latching component 361, an effective force application point can be provided for the latching component 361, making it convenient for the user to apply force to the latching component 361.

[0098] Please continue to refer to Figure 12 and Figure 13 In this embodiment, a protrusion 365 is provided on the side of the bearing section 3622 facing away from the frame 300. By providing the protrusion 365, on the one hand, it can provide a certain limiting and supporting function for the mounting box 200 after it is assembled in place; on the other hand, it can also increase the structural strength of the bearing section 3622 and reduce the risk of damage to the bearing section 3622 during long-term use.

[0099] When the mounting box 200 needs to be connected to the first buckle 360 ​​via the snap-fit ​​hole 252, the snap-fit ​​hole 252 is engaged with the first buckle 360. During this process, the snap-fit ​​hole 252 slides into the buckle component 361 via the guide ramp 3611 and is supported and fixed by the protrusion 365 and the main structure of the buckle component 361. During the disassembly of the mounting box 200, pressing the button 364 causes the first buckle 360 ​​to deform, causing the snap-fit ​​hole 252 to disengage from the buckle component 361, thereby releasing the first buckle 360 ​​from limiting the snap-fit ​​hole 252, and thus achieving the purpose of disassembling the mounting box 200.

[0100] Please continue to refer to Figure 8 and Figure 10 In this embodiment, the mounting box 200 is provided with a plurality of second buckles 240 inside. The plurality of second buckles 240 are arranged at intervals along the contour edge of the mounting box 200, specifically, at intervals along the edge of the opening. The air detection sensor 100 is fixed to the mounting box 200 by the plurality of second buckles 240.

[0101] This method of fixing the air detection sensor 100 to the mounting box 200 by snap-fit ​​is not only simple in structure, but also facilitates the quick installation and removal of the air detection sensor 100.

[0102] In this embodiment, the projection of the main body of the mounting box 200 along the set direction is rectangular, and there are three second buckles 240, one of which is located on the short side of the rectangle, and the other two are located on the two long sides of the rectangle respectively.

[0103] Please continue to refer to Figure 9 and Figure 10 In this embodiment, the air detection sensor 100 has a substrate 120, and the detection chip 110 is fixedly disposed on the substrate 120. The air detection sensor 100 is fixedly engaged with the second buckle 240 through the substrate 120.

[0104] In this embodiment, the second latch 240 is provided with a 50° large angled guide surface, which makes it easy for the substrate 120 to be snapped into the second latch 240.

[0105] Please continue to refer to Figure 8 The mounting box 200 has a positioning post 260 fixed inside. Please refer to [the documentation / reference]. Figure 9 The air detection sensor 100 has a positioning hole 130, which mates with the positioning post 260. The mating of the positioning hole 130 and the positioning post 260 is as follows: Figure 10 As shown. Specifically, in this embodiment, the positioning hole 130 is formed on the substrate 120 of the air detection sensor 100.

[0106] When it is necessary to assemble the air detection sensor 100 into the mounting box 200, the positioning hole 130 can be aligned with the positioning post 260 of the mounting box 200 first, and then the air detection sensor 100 can be pressed towards the vent 220 so that the substrate 120 can be snapped into the second snap 240, thereby achieving the assembly purpose.

[0107] By setting a positioning post 260 in the mounting box 200 and a positioning hole 130 in the air detection sensor 100 to cooperate with it, the positioning of the air detection sensor 100 during the assembly process is achieved, ensuring the installation accuracy of the air detection sensor 100, and thus ensuring its detection accuracy.

[0108] Please continue to refer to Figure 8 , Figure 10 and Figure 11 In this embodiment, the mounting box 200 is also provided with an abutment part 270. Specifically, the abutment part 270 is configured to abut against the air detection sensor 100 after the air detection sensor 100 is engaged with the second buckle 240.

[0109] The contact part 270 is provided to support the air detection sensor 100 and ensure the installation stability of the air detection sensor 100.

[0110] In this embodiment, two sets of contact portions 270 are provided, one set on each long side of the mounting box 200, and each set includes two contact portions 270. The contact portions 270 provided on the two long sides of the mounting box 200 are symmetrical about the midline of the long axis of the mounting box 200. This arrangement increases the number of support points of the mounting box 200 for the air detection sensor 100, ensuring that the air detection sensor 100 is subjected to uniform force.

[0111] Please continue to refer to Figures 7 to 10 In this embodiment, a wire hole 280 is provided on the side wall of the mounting box 200. The wire hole 280 is configured to allow the electrical connection wire 150 of the air detection sensor 100 to pass through.

[0112] This configuration ensures an effective connection between the air detection sensor 100 and the controller 600, while also preventing damage to the electrical connection wire 150 at the connection between the mounting box 200 and the frame 300.

[0113] Please continue to refer to Figure 9 and Figure 10 In this embodiment, the air detection sensor 100 also includes a plug-in terminal 140, and an electrical connection wire 150 is connected to the plug-in terminal 140. The mounting box 200 is provided with an anti-detachment rib 290. When the air detection sensor 100 and the mounting box 200 are assembled, the anti-detachment rib 290 is located between the detection chip 110 and the wire hole 280. The anti-detachment rib 290 is used to cooperate with the plug-in terminal 140.

[0114] This setup utilizes the anti-detachment ribs 290 to block the plug-in terminal 140, thereby preventing the plug-in terminal 140 from detaching and ensuring the reliability of the electrical connection between the detection chip 110 and the controller 600.

[0115] Please continue to refer to Figures 7 to 10 In this embodiment, the wire hole 280 is an open hole, and the open part of the wire hole 280 is provided with a beak bracket 281. The beak bracket 281 is configured to prevent the electrical connection wire 150 from falling off from the open part.

[0116] This setting allows for smooth routing of the electrical connection cable 150 without requiring it to pass through one end of the cable hole 280 to the other, thus improving routing efficiency. On the other hand, it also provides a certain degree of restraint for the electrical connection cable 150, preventing it from falling out of the cable hole 280 without external force.

[0117] In this embodiment, the beak bracket 281 is an elastic buckle, which can be used to install and remove the electrical connection cable 150 by pressing.

[0118] Please continue to refer to Figure 2 and Figure 4 In this embodiment, the frame 300 is provided with a wiring groove 380, which is configured to accommodate the electrical connection wire 150 of the air detection sensor 100.

[0119] By setting the wiring trough 380 in the frame 300, the electrical connection wire 150 can be accommodated. On the one hand, this prevents the electrical connection wire 150 from being crushed by other components in the air conditioner indoor unit. On the other hand, it also ensures the neatness of the wiring and prevents the electrical connection wire 150 from getting tangled with other components.

[0120] Please continue to refer to Figure 4 In this embodiment, the wiring groove 380 may include at least two structural forms. One is to create a groove on the surface of the block-shaped component, using this grooved structure to form the wiring groove 380, such as... Figure 4 The wiring groove 380 on the left side; another possibility is that it can be formed by a local structural recess in the frame 300, specifically as follows: Figure 4 The cable tray on the right side is 380.

[0121] Please continue to refer to Figure 2 and Figure 4 In this embodiment, the frame 300 is fixedly provided with a wire clamp 390. Specifically, the wire clamp 390 is configured to fix the electrical connection wire 150 to the frame 300. The wire clamp 390 can effectively fix the electrical connection wire 150 in the wiring groove 380 and prevent the electrical connection wire 150 from accidentally falling out of the wiring groove 380.

[0122] In this embodiment, there are three wire clamps 390, which are arranged at intervals along the direction of the electrical connection line 150. This arrangement increases the number of fixing points for the electrical connection line 150, thereby improving the reliability of fixing the electrical connection line 150 and reducing the possibility of local sag of the electrical connection line 150.
