[0065] The embodiments of this utility model 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0066] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0067] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to an embodiment of the present invention will be described.

[0068] refer to Figure 1 and Figure 2 The window air conditioner 100 includes an indoor unit 1 adapted to be installed on the indoor side and an outdoor unit 2 adapted to be installed on the outdoor side. The indoor unit 1 includes an air detection device 11, which includes at least one of a humidity sensor 111 and an air quality sensor 112.

[0069] For example, the indoor unit 1 has a ventilation space communicating with the indoor side, and the detection head of the air detection device 11 is connected to the ventilation space. As a key component that directly interacts with indoor air, the indoor unit 1 has a ventilation space communicating with the indoor side. The ventilation space refers to the area where the indoor unit 1 can communicate with the indoor air. The connection between the detection head of the air detection device 11 and the ventilation space allows the detection head to come into contact with the indoor air, enabling it to acquire relevant information about the indoor air.

[0070] For example, the air quality detection device 11 can transmit the detected information to the control system of the window air conditioner 100 so that the window air conditioner 100 can automatically make corresponding adjustments based on the detection data. Alternatively, the air quality detection device 11 can display the detected information to the user, for example through screen display, voice announcement, or color-changing light, thereby prompting the user to take appropriate action.

[0071] For example, the air detection device 11 can transmit the detected information to the control system of the window air conditioner 100. The control system of the window air conditioner 100 can automatically adjust the operating mode and parameters according to preset programs and algorithms. For example, when the indoor humidity is detected to be too high, the window air conditioner 100 can automatically start the dehumidification function; when the indoor humidity is detected to be too low, the window air conditioner 100 can automatically start the humidification function (when the window air conditioner 100 has a humidification function); when the air quality is detected to be poor, the air purification function can be started in time (when the window air conditioner 100 has an air purification function). This eliminates the need for frequent manual operation by the user, improving the convenience and comfort of use.

[0072] Among them, the air quality sensor 112 refers to a sensor used to detect the concentration of at least one pollutant in indoor air. The air quality sensor 112 can detect one or more of inhalable particulate matter (such as PM2.5, PM10), volatile organic compounds (VOCs), carbon dioxide (CO2), or formaldehyde.

[0073] For example, when the air quality sensor 112 detects that the concentration of a certain pollutant exceeds a preset threshold, the window air conditioner 100 activates the air purification function, such as filtering, adsorbing, or catalytically decomposing the pollutants that need to be purified, in order to improve indoor air quality and provide users with a healthy and comfortable indoor environment.

[0074] In the embodiments of this application, the location of the air detection device 11 is not limited.

[0075] For example, the humidity sensor 111 can be located on the front, rear, left, right, top, bottom, etc. of the indoor unit 1. For example, the humidity sensor 111 can be located in the surrounding area of ​​the air intake area 122a of the indoor unit 1, thereby enabling rapid detection of the indoor air humidity entering the indoor unit 1 and reliably reflecting the indoor air humidity.

[0076] For example, the air quality sensor 112 can be located on the front, rear, left, right, top, or bottom side of the indoor unit 1. For example, the air quality sensor 112 can be located in a well-ventilated area with gentle airflow. For instance, the air quality sensor 112 can be located adjacent to the air intake area 122a of the indoor unit 1, where airflow is relatively stable, and the detected data is more representative of the indoor air quality. This can reduce detection errors caused by unstable local airflow.

[0077] In the technical solution of this application, the functions of the window air conditioner 100 can be enriched by setting an air detection device 11 in the indoor unit section 1. The window air conditioner 100 can be further designed to directly reflect the detected data to the customer, or it can be further designed to adjust its own operating mode or operating parameters according to the detected data, thereby providing users with a more comfortable and healthy indoor environment.

[0078] refer to Figure 1 and Figure 2 In some embodiments, the indoor unit 1 has an air intake area 122a on at least one side, and the humidity sensor 111 is disposed on the same side as the air intake area 122a on that side, and is located around the air intake area 122a on the corresponding side. That is, when the indoor unit 1 has an air intake area 122a on only one side, the humidity sensor 111 is disposed on the same side as the air intake area 122a on that side; when the indoor unit 1 has air intake areas 122a on multiple sides, the humidity sensor 111 is disposed on the same side as the air intake area 122a on one of the sides.

[0079] In the above technical solution, the humidity sensor 111 is set on the same side as the air intake area 122a on one side, and is located around the air intake area 122a on the corresponding side. Therefore, the air detected by the humidity sensor 111 is the upstream air drawn into the window air conditioner 100. The humidity of this air is not easily affected by the humidity of the components or environment inside the window air conditioner 100, and is closer to the true humidity of the indoor air. Moreover, the humidity sensor 111 is set in a position where the indoor air flow rate is relatively moderate, which is more conducive to the humidity sensor 111 reflecting the indoor air humidity more accurately, and providing reliable data for the window air conditioner 100 to accurately adjust the indoor humidity.

[0080] refer to Figure 2 In some embodiments, the indoor unit 1 includes a housing 12 and a ventilation and heat exchange component 13 disposed within the housing 12. The housing 12 includes a face frame 121 and an air inlet grille 122. The face frame 121 includes a frame opening 1211 and a first frame edge 1212 disposed around the frame opening 1211. The air inlet grille 122 covers the frame opening 1211 and the first frame edge 1212. The air inlet grille 122 defines an air inlet area 122a on one side. A humidity sensor 111 is installed on the first frame edge 1212 and communicates with the indoor side through the air inlet grille 122.

[0081] In the above technical solution, the humidity sensor 111 is installed on the first frame edge 1212 and connected to the indoor side through the air inlet grille 122. The air inlet grille 122 covers the frame opening 1211 and the first frame edge 1212. The humidity sensor 111 is installed on the first frame edge 1212, which simplifies the overall structure. The air inlet grille 122 can protect the humidity sensor 111 to a certain extent and improve the detection accuracy of the humidity sensor 111.

[0082] For example, the air inlet grille 122 is detachable from the face frame 121. This makes the air inlet grille 122 easy to install and remove when it covers the frame opening 1211 and the first frame edge 1212. It also allows for quick opening of the air inlet grille 122 for inspection and maintenance when repairing or maintaining the humidity sensor 111.

[0083] refer to Figure 1 In some embodiments, the indoor unit 1 and the outdoor unit 2 are spaced apart in the horizontal direction to form a receiving space 3 between the indoor unit 1 and the outdoor unit 2, and an air intake grille 122 is provided on the side of the indoor unit 1 facing the receiving space 3.

[0084] For example, the side of the indoor unit 1 facing the outdoor unit 2 is the rear side, and the side of the indoor unit 1 away from the outdoor unit 2 is the front side. An air inlet grille 122 is provided on the side of the indoor unit 1 facing the accommodating space 3, that is, an air inlet grille 122 is provided on the rear side of the indoor unit 1. This makes full use of the rear area of ​​the indoor unit 1. The air inlet grille 122 can provide more space for the air outlet area, and at the same time, it makes it less likely for the airflow entering the air inlet grille 122 to cross with the airflow blowing out of the air outlet area, thereby helping to improve the problem of short-circuiting of return air.

[0085] refer to Figures 2-5 In some embodiments, the side of the indoor unit 1 facing the outdoor unit 2 is the rear side, and the side of the indoor unit 1 away from the outdoor unit 2 is the front side. The front frame 121 includes a rear frame 121a located behind the ventilation and heat exchange component 13, and a side frame 121b located on the left or right side of the ventilation and heat exchange component 13. The humidity sensor 111 is connected to a first wiring harness 1111. The humidity sensor 111 is installed on the rear side of the rear frame 121a. The first wiring harness 1111 passes through the rear frame 121a to the inside of the front frame 121, and then passes through the inside of the front frame 121 to the outside of the side frame 121b. The housing 12 includes a side decorative panel 124, which covers the outside of the side frame 121b and blocks the first wiring harness 1111.

[0086] The inner side of the face frame 121 refers to the side of the face frame 121 closest to the center of the indoor unit component 1, and the outer side of the face frame 121 refers to the side of the face frame 121 furthest from the center of the indoor unit component 1. The face frame 121 may have multiple frame plates (e.g., upper frame, front frame, rear frame 121a, and two side frames 121b), and is in the form of a frame body and is fitted over the ventilation and heat exchange component 13.

[0087] The installation method of the side decorative panel 124 is not limited. For example, the side decorative panel 124 can be connected and fixed to the side frame 121b by a buckle; for example, the side decorative panel 124 can be fixedly connected to the side frame 121b by screws; for example, magnetic materials are installed at corresponding positions of the side decorative panel 124 and the side frame 121b, and the side decorative panel 124 is fixed to the side frame 121b by magnetic attraction.

[0088] In the above technical solution, the humidity sensor 111 is installed on the outside of the face frame 121, which facilitates the positioning and fixing of the humidity sensor 111 during installation and also facilitates subsequent maintenance and other operations. The first wire harness 1111 passes through the face frame 121 to the inside of the housing 12, and then passes through the inside of the housing 12 via the side frame 121b to the outside of the side frame 121b, instead of being set from the outside of the face frame 121 to the outside of the side frame 121b. This reduces the risk of the wire harness being randomly wrapped or exposed on the outside of the housing 12, thereby improving the reliability and stability of the entire window air conditioner 100.

[0089] For example, the first wiring harness 1111 is connected to the first pair of wiring harnesses 171 of the display component of the indoor unit 1 on the outside of the side frame 121b. The side decorative panel 124 is covered outside the side frame 121b and shields the first wiring harness 1111 and the first pair of wiring harnesses 171, thereby protecting the first wiring harness 1111 and the first pair of wiring harnesses 171 and preventing external objects from accidentally colliding with the wiring harness and protecting the wiring harness from damage.

[0090] refer to Figures 8-10 In some embodiments, the ventilation and heat exchange component 13 includes a heat exchanger 131 and a refrigerant connection pipe 132, the refrigerant connection pipe 132 being located on the side of the heat exchanger 131 near the side frame 121b, in conjunction with... Figure 4 and Figure 5 The inner wall of the housing 12 has a first wire harness structure 129 for constraining the first wire harness 1111. The form of the first wire harness structure 129 is not limited; for example, it can be a wire groove type, a wire clip type, a wire harness with a fixing strap, etc. The refrigerant connection pipe 132 is used to connect the heat exchanger 131 to the outdoor unit 2.

[0091] In the above technical solution, the first wire bundle structure 129 constrains the first wire bundle 1111, thereby making the wiring of the first wire bundle 1111 more secure and reducing the shaking and wear of the first wire bundle 1111, or the damage to the first wire bundle 1111 caused by the squeezing of components such as the heat exchanger 131.

[0092] For example, such as Figure 6 and Figure 7As shown, the humidity sensor 111 is mounted on the first frame edge 1212 via a sliding groove structure 12121. The first frame edge 1212 is also provided with an upper stop buckle 121211 and a lower stop buckle 121212. The humidity sensor 111, which cooperates with the sliding groove structure 12121, abuts against the upper stop buckle 121211 and the lower stop buckle 121212. The first wire harness 1111 extends from the lower part of the humidity sensor 111. A wiring notch 12122 is provided below the lower stop buckle 121212 so that the first wire harness 1111 passes from the outside of the face frame 121 to the inside of the face frame 121. Figure 4 and Figure 5 A first wire bundle structure 129 is provided on the inner wall of the face frame 121 at the position corresponding to the wiring notch 12122, so as to constrain the first wire bundle 1111 to turn and extend to one side of the side frame 121b, combined with Figure 2 and Figure 3 A wire hole 1232 is provided on the side frame 121b, and the first wire harness 1111 passes through the wire hole 1232 to the outside of the side frame 121b.

[0093] Combination Figures 8-10 A refrigerant connection pipe 132 is provided on the side of the heat exchanger 131 near the side frame 121b. The first wire harness structure 129 can effectively isolate the first wire harness 1111 from the refrigerant connection pipe 132 around the first wire harness 1111, preventing the refrigerant connection pipe 132 from vibrating and rubbing against the first wire harness 1111 due to the compressor, which would cause damage to the insulation layer of the first wire harness 1111 and ensure stable signal transmission of the humidity sensor 111. At the same time, it reduces the possibility of thermal damage to the first wire harness 1111 caused by the refrigerant connection pipe 132 when transporting hot refrigerant, thus preventing the first wire harness 1111 from aging rapidly.

[0094] refer to Figure 3 In some embodiments, the ventilation and heat exchange component 13 includes a heat exchanger 131 and a refrigerant connection pipe 132. The refrigerant connection pipe 132 is disposed on the side of the heat exchanger 131 near the side frame 121b. The outer wall of the side frame 121b has a second wire harness structure 1231 for constraining the first wire harness 1111. Thus, the second wire harness structure 1231 can fix the first wire harness 1111 to the outer wall of the side frame 121b, reducing the probability of wire harness wear, short circuits, and other faults.

[0095] refer to Figures 8-10 In some embodiments, the ventilation and heat exchange component 13 includes a heat exchanger 131 and a refrigerant connection pipe 132. The refrigerant connection pipe 132 is disposed on the side of the heat exchanger 131 near the side frame 121b. The inner wall of the housing 12 is formed with a first wire harness structure 129 for constraining the first wire harness 1111. (See reference) Figure 3 The outer wall of the side frame 121b has a second wire structure 1231 for constraining the first wire harness 1111.

[0096] In the above technical solution, the second wire harness structure 1231 and the first wire harness structure 129 form multiple constraints on the first wire harness 1111. The multiple wire harness structure can more comprehensively restrict the range of motion of the wire harness, allowing the first wire harness 1111 to extend according to the design direction, avoiding the first wire harness 1111 from swinging or tangling at will, reducing the risk of friction and collision between the wire harness and other components (such as heat exchanger 131), preventing damage to the wire harness insulation layer, thereby improving the reliability of wire harness management and ensuring stable signal transmission of humidity sensor 111.

[0097] refer to Figure 6 In some embodiments, the humidity sensor 111 is mounted on the first frame edge 1212 via a sliding groove structure 12121. This simplifies the installation process of the humidity sensor 111 and facilitates subsequent maintenance and repair. Furthermore, the sliding groove structure 12121 can limit the movement of the humidity sensor 111, reducing the risk of it shaking or shifting due to vibration or other factors during operation of the window air conditioner 100. A stable installation ensures sufficient contact between the humidity sensor 111 and the indoor air, making the detected humidity data more accurate and reliable.

[0098] For example, such as Figure 6 and Figure 7 As shown, the humidity sensor 111 is mounted on the first frame edge 1212 via a sliding groove structure 12121. The sliding groove structure 12121 includes two elongated sliding grooves 121213 extending vertically on the left and right sides. The two elongated sliding grooves 121213 are used to hold the edge of the main PCB board of the humidity sensor 111. When assembling the humidity sensor 111, it slides upward or downward along the elongated sliding grooves 121213. When the sensor is mounted in place, the upper edge of the humidity sensor 111 is stopped and limited by the upper stop buckle 121211. The lower edge is provided with two opposing lower stop buckles 121212 below the two elongated sliding grooves 121213, so that the humidity sensor 111 is engaged between the upper stop buckle 121211 and the lower stop buckle 121212, thereby allowing the humidity sensor 111 to be stably fixed in the sliding groove structure 12121 and easy to disassemble. The first wiring harness 1111 extends from the lower part of the humidity sensor 111 and is located between the two lower stop buckles 121212. The first wiring harness 1111 extends downward along the slide groove structure 12121 to the wiring notch 12122, so that the first wiring harness 1111 passes from the outside of the face frame 121 to the inside of the face frame 121.

[0099] refer to Figure 2In some embodiments, the air inlet grille 122 is detachable or openable at least at the location corresponding to the humidity sensor 111. The air inlet grille 122 may be entirely detachable or openable, or a portion of the air inlet grille 122 may be detachable or openable, such as by providing a maintenance cover at the location corresponding to the humidity sensor 111, and the maintenance cover being detachable or openable.

[0100] For example, the detachable installation method of the air intake grille 122 can be: snap-on detachable installation, screw-fixed detachable installation, pin-type detachable installation, etc.; the detachable installation method of the air intake grille 122 can be: hinge type, sliding rail type, swivel type, etc.

[0101] During long-term use of the window air conditioner 100, the humidity sensor 111 may malfunction or experience a decrease in detection accuracy due to dust accumulation, moisture, aging, or other reasons. When the air inlet grille 122 is detachable or openable at least at the location corresponding to the humidity sensor 111, maintenance personnel do not need to perform a large-scale disassembly of the entire window air conditioner 100. They can directly access the humidity sensor 111 by simply removing or opening the corresponding part of the air inlet grille 122. This shortens maintenance time, reduces maintenance difficulty and cost, and improves the maintainability of the window air conditioner 100.

[0102] In some embodiments, reference Figure 6 The humidity sensor 111 is mounted on the first frame edge 1212 via a sliding groove structure 12121, for reference. Figure 2 The air inlet grille 122 is detachable or openable at least at the location corresponding to the humidity sensor 111. This facilitates the installation and maintenance of the humidity sensor 111. It also makes the humidity sensor 111 easier to install and remove quickly, improving its maintainability.

[0103] refer to Figure 6 In some embodiments, the humidity sensor 111 is connected to a first wiring harness 1111, which extends from the humidity sensor 111, bends downwards, and then extends upwards.

[0104] In the operating environment of the window air conditioner 100, water may come into contact with the humidity sensor 111 and its connected first wiring harness 1111 due to condensation, high air humidity, or accidental water spillage. The first wiring harness 1111 extends from the humidity sensor 111, bends downwards, and then extends upwards, forming a U-shaped structure. When water flows along the surface of the first wiring harness 1111, it drips downwards at the bend due to gravity, preventing it from continuing upwards and intruding into the humidity sensor 111, thus reducing the risk of damage to the humidity sensor 111 due to water intrusion.

[0105] For example, such as Figure 3 , Figure 4 and Figure 5 As shown, the first wire harness 1111 extends from the lower part of the humidity sensor 111 to the wiring notch 12122 of the humidity sensor 111, and then runs into the housing 12 to pass through the inner side of the face frame 121. The inner wall of the face frame 121 is provided with a first wire harness structure 129 corresponding to the position of the wiring notch 12122 to constrain the first wire harness 1111 to turn and extend to one side of the side frame 121b. The side frame 121b is provided with a wire through hole 1232. The first wire harness 1111 The wires pass through the wire hole 1232 to the outside of the side frame 121b. The outer wall of the side frame 121b has a second wire harness structure 1231 for constraining the first wire harness 1111. The first wire harness 1111 then continues to run to the front of the indoor unit 1 and finally plugs into the first pair of wire harnesses 171 that are led out to the rear of the front display component of the indoor unit 1. The first plug-in terminal 173 formed by the plugging is fixed on the first terminal fixing buckle 1233 on the outer wall of the side frame 121b.

[0106] The wiring notch 12122 is lower than the humidity sensor 111, the wire hole 1232 is higher than the wiring notch 12122, the second wire bundle structure 1231 is higher than the wire hole 1232, and the first terminal fixing buckle 1233 is higher than the second wire bundle structure 1231. When water flows along the first wire bundle 1111, due to gravity, the water will drip down at the bend of the wiring notch 12122 and will not continue to enter the humidity sensor 111 along the first wire bundle 1111, nor will it flow to the first plug terminal 173.

[0107] refer to Figure 11 In some embodiments, at least one side of the indoor unit 1 has an air intake area 122a, and the air quality sensor 112 is a particulate matter sensor 112a, which is located on the adjacent side of the air intake area 122a on one side. It is understood that the window air conditioner 100 has multiple sides, such as front, rear, left, right, top, bottom, etc., and each adjacent two sides are adjacent sides. For example, the adjacent sides of the rear side can be the left, right, top, and bottom sides. Therefore, if the air intake area 122a is located on the rear side, the particulate matter sensor 112a can be located on at least one of the left, right, top, and bottom sides.

[0108] In the above technical solution, the particulate matter sensor 112a is placed on the adjacent side of the air intake area 122a on one side of the indoor unit 1, utilizing the characteristic that the air intake area 122a can introduce indoor air to form a relatively stable airflow. During air conditioning operation, the air intake area 122a continuously draws in indoor air, forming a relatively moderate and stable airflow field on the adjacent side of the air intake area 122a. In such an airflow environment, the particulate matter sensor 112a can more evenly and continuously contact the particulate matter in the indoor air, reducing detection errors caused by turbulent airflow, excessively fast or slow flow rates. For example, if the sensor is placed in a dead airflow area, it may not be able to detect changes in particulate matter in the air in a timely manner; while if placed in an area with excessively fast airflow, particulate matter may not be accurately captured due to airflow impact. The stable and moderately velocity airflow allows the particulate matter sensor 112a to detect particulate matter relatively accurately and reliably, such as detecting the concentration of particulate matter in indoor air.

[0109] For example, the particulate sensor 112a is an infrared particulate sensor. Since the infrared particulate sensor obtains air particulate data by illuminating the air projection and counting the particulate matter, the airflow velocity entering the module needs to be stable and relatively slow. The infrared particulate sensor is placed on the adjacent side of the air inlet area 122a. For example, the infrared particulate sensor is placed on the side frame 121b, and the side decorative plate 124 is covered outside the side frame 121b. The side decorative plate 124 is provided with ventilation holes corresponding to the infrared particulate sensor. Compared with placing the infrared particulate sensor near the air inlet or air outlet 128, the detection error caused by airflow turbulence, excessively fast or slow flow velocity can be reduced.

[0110] Among them, infrared particulate matter sensors have a simple structure and working principle, and the manufacturing process is also relatively simple. When a fault occurs, it is easier for maintenance personnel to diagnose and repair it. The required maintenance parts are also more common, which reduces the later maintenance costs.

[0111] For example, the particulate sensor 112a is a laser particulate sensor. The laser particulate sensor uses the principle of laser scattering to accurately detect particulate matter (such as PM2.5 and PM10) in the air. It can detect particles with extremely small diameters, has a fast response time, and can detect changes in the concentration of particulate matter in the air within a short period of time.

[0112] refer to Figure 11 In some embodiments, the side of the indoor unit 1 facing the outdoor unit 2 is the rear side, and the side of the indoor unit 1 away from the outdoor unit 2 is the front side. The air quality sensor 112 is located on the left and / or right side of the indoor unit 1.

[0113] In the above technical solution, the air quality sensor 112 is located on the left and / or right side of the indoor unit 1, allowing maintenance personnel to observe the air quality sensor 112 more intuitively and facilitating maintenance operations. Compared to locations on the front or rear of the indoor unit, side positions typically have fewer obstructing components; for example, the front may have an air outlet 128, a grille, or a display screen, while the rear is close to a wall or window. The sides of the indoor unit 1 usually have relatively spacious areas, facilitating disassembly and installation using tools, thus improving the ease of maintenance of the air quality sensor 112.

[0114] refer to Figure 11 In some embodiments, the indoor unit 1 and the outdoor unit 2 are spaced apart in the horizontal direction to form a receiving space 3 between the indoor unit 1 and the outdoor unit 2. The air inlet area 122a of the indoor unit 1 is located on the rear side and / or bottom side of the indoor unit 1, and the air outlet 128 of the indoor unit 1 is located on the front or upper front part of the indoor unit 1.

[0115] In the above technical solution, an accommodating space 3 is formed between the indoor unit 1 and the outdoor unit 2. The air inlet area 122a is located on the rear side and / or bottom side of the indoor unit 1. Thus, the air inlet area 122a can provide more space for the air outlet 128. Combined with the fact that the air outlet 128 is located at the front or upper front part of the indoor unit 1, the airflow entering the air inlet area 122a is less likely to cross with the airflow blown out of the air outlet 128, which helps to improve the problem of short-circuiting of return air.

[0116] In the above technical solution, the air inlet area 122a of the indoor unit 1 is located on the rear side and / or bottom side of the indoor unit 1, and the air outlet 128 of the indoor unit 1 is located on the front or upper front part of the indoor unit 1. This air inlet and outlet layout allows the air to form a relatively stable flow path in the room. As a result, the airflow field around the indoor unit 1 is relatively stable. Combined with the fact that the air quality sensor 112 is located on the side of the indoor unit 1, the airflow on the side is stable and the wind speed is low, which reduces the detection error caused by airflow turbulence, excessively fast or slow flow speed, and improves the detection accuracy of the air quality sensor 112.

[0117] refer to Figure 11 and Figure 12 In some embodiments, the indoor unit 1 includes a housing 12 and a ventilation and heat exchange component 13 disposed within the housing 12. The housing 12 includes an inner frame 125 and an outer decorative panel 126. An air quality sensor 112 is disposed on the inner frame 125, and the outer decorative panel 126 covers the outside of the inner frame 125. A ventilation hole 1262a is provided at the location corresponding to the air quality sensor 112.

[0118] In the above technical solution, the air quality sensor 112 is located on the inner frame 125, and the corresponding position of the outer decorative panel 126 is provided with a ventilation hole 1262a, so that indoor air can come into contact with the air quality sensor 112 on the inner frame 125 through the ventilation hole 1262a, ensuring that the sensor can monitor changes in indoor air quality in a timely and accurate manner; installing the air quality sensor 112 on the inner frame 125 provides a spacious and convenient operating space for installers compared to installing it in other positions. This improves installation efficiency and facilitates subsequent maintenance and repair. An air quality sensor 112 is installed on the inner frame 125, allowing the wiring harness of the air quality sensor 112 to be laid along the reserved wire groove of the inner frame 125, reducing the messy distribution of the wiring harness and reducing the risk of interference and short circuits between the wiring harnesses. The outer decorative panel 126 is covered on the outside of the inner frame 125, hiding the air quality sensor 112, wiring harness and other components on the inner frame 125. From the outside, only the neat outer decorative panel 126 is visible, making the overall appearance of the window air conditioner 100 more tidy.

[0119] The inner frame 125 can be positioned anywhere, such as on the left or right side, the rear or front side, the top or bottom side, etc. When it is positioned on the left or right side, the inner frame 125 and the side frame 121b can be the same, and the outer decorative panel 126 and the side decorative panel 124 can also be the same.

[0120] refer to Figure 11 and Figure 12 In some embodiments, the outer trim panel 126 can be completely disassembled or opened. During the later maintenance and repair of the air conditioner, maintenance personnel can maintain or replace the air quality sensor 112 located on the inner frame 125 by completely disassembling or opening the outer trim panel 126.

[0121] refer to Figure 11 and Figure 12 In some embodiments, the outer decorative panel 126 includes a panel body 1261 and a movable cover 1262. The movable cover 1262 is provided corresponding to the air quality sensor 112. The panel body 1261 has an opening 1261a. The movable cover 1262 is movable or detachable relative to the panel body 1261 to open or close the opening 1261a. A ventilation hole 1262a is provided on the movable cover 1262.

[0122] In the above technical solution, when maintenance is required on the air quality sensor 112, it is not necessary to disassemble the entire outer decorative panel 126. Simply opening or removing the movable cover 1262 allows for direct cleaning, calibration, or replacement of the air quality sensor 112. For example, if the air quality sensor 112 becomes inaccurate due to dust accumulation, the movable cover 1262 can be opened to wipe the surface of the air quality sensor 112, restoring its normal detection function and improving the convenience and timeliness of maintenance.

[0123] For example, such as Figure 13 As shown, the movable cover 1262 is mounted on the panel body 1261 via a pivot and can rotate around the pivot to open and close the opening 1261a. A latch is provided on the edge of the movable cover 1262 away from the pivot, engaging with the panel body 1261. Of course, the opening method of the movable cover 1262 is not limited to this; for example, it can also be opened by sliding, etc.

[0124] refer to Figure 12 and Figure 14 In some embodiments, the air quality sensor 112 is connected to a second wiring harness 1121, at least a portion of which extends outside the inner frame 125. An outer decorative panel 126 covers the second wiring harness 1121, and the outer wall of the inner frame 125 has a third wire harness structure 1251 for constraining the second wiring harness 1121.

[0125] For example, the second wiring harness 1121 of the air quality sensor 112 is plugged into the second pair of wiring harnesses 172 that are led out to the rear side of the front display component of the indoor unit 1. The second pair of plug terminals 174 formed by the plugging are fixed on the second terminal fixing buckle 1253 on the outer wall of the inner frame 125. The outer decorative panel 126 is covered from the side to the outer side of the inner frame 125 to effectively protect the second wiring harness 1121 and the second pair of plug terminals 174.

[0126] In the above technical solution, the second wiring harness 1121 of the air quality sensor 112 and the second pair of wiring harnesses 172 are connected on the outside of the inner frame 125, instead of connecting the wiring harnesses from the inside of the inner frame 125. This reduces the number of wiring harnesses arranged inside the indoor unit 1 and reduces the mutual entanglement and interference between the wiring harnesses. Connecting the wiring harnesses in the space outside the inner frame 125 eliminates the need for complex wiring and connection operations inside the narrow indoor unit 1, thus improving assembly efficiency.

[0127] The outer decorative panel 126 covers the second wire harness 1121, which can effectively prevent external objects from colliding, scratching and squeezing the wire harness, and avoid damage to the wire harness due to external forces; the third wire harness structure 1251 on the outer wall of the inner frame 125 can constrain the second wire harness 1121, so that the second wire harness 1121 is arranged according to a predetermined path and position, preventing the second wire harness 1121 from shaking and shifting at will, and facilitating the management and maintenance of the second wire harness 1121.

[0128] refer to Figure 12 and Figure 14 In some embodiments, the indoor unit 1 includes a mounting box 14, which has a first through-hole 141 on the side facing the outer decorative panel 126. The mounting box 14 has a receiving cavity 142, in which an air quality sensor 112 is disposed. The detection head 1122 of the air quality sensor 112 is directly opposite the first through-hole 141. The mounting box 14 is mounted on the inner frame 125 from the outside of the inner frame 125.

[0129] In the above technical solution, the air quality sensor 112 is placed in the receiving cavity 142 of the mounting box 14, and its detection head 1122 is directly facing the first through hole 141, so that the air quality sensor 112 can contact the indoor air through the first through hole 141, thereby enabling the air quality sensor 112 to detect the indoor air quality in real time and accurately.

[0130] In the above technical solution, the air quality sensor 112 is housed in the receiving cavity 142, which can reduce the interference of external objects, dust erosion, and water vapor on the measurement of the air quality sensor 112, thereby improving the measurement accuracy of the air quality sensor 112. The mounting box 14 is installed on the inner frame 125 from the outside of the inner frame 125, which facilitates the installation of the mounting box 14. Moreover, when the air quality sensor 112 needs to be maintained or replaced in the future, maintenance personnel can also easily disassemble and install the mounting box 14 from the outside of the inner frame 125, reducing maintenance time and costs.

[0131] In the embodiments of this application, the mounting box 14 is fixed to the inner frame 125 from the outside of the inner frame 125 in any way. For example, it can be fixed by screws, snap-fit ​​connection, magnetic installation, etc.

[0132] refer to Figure 2 and Figure 15In some embodiments, the indoor unit 1 includes a mounting base 15, which has a second through-hole 151 on the side facing the outer decorative panel 126. The mounting base 15 defines a receiving groove 152 that opens away from the outer decorative panel 126. An air quality sensor 112 is disposed in the receiving groove 152, with the detection head 1122 of the air quality sensor 112 facing the second through-hole 151. The mounting base 15 is integrated with the inner frame 125. The air quality sensor 112 is mounted in the receiving groove 152 from the inside of the inner frame 125. A fixing cover 127 is also provided inside the housing 12. The fixing cover 127 is assembled and connected to the mounting base 15. The air quality sensor 112 is located between the mounting base 15 and the fixing cover 127.

[0133] In the above technical solution, the detection head 1122 of the air quality sensor 112 is directly facing the second through-hole 151, ensuring that indoor air can directly and smoothly enter the receiving groove 152 through the second through-hole 151 and come into contact with the detection head 1122, so that the sensor can perceive changes in air quality in real time and accurately.

[0134] In the above technical solution, the receiving slot 152 provides a relatively independent space for the air quality sensor 112, which can isolate external interference factors to a certain extent, such as unstable fluctuations in airflow and vibrations of surrounding components. The fixed cover 127 installed from the inside is not easily damaged or detached by external impacts, which helps the air quality sensor 112 to work in a relatively stable environment.

[0135] For example, the air quality sensor 112 is an infrared particulate sensor. The air quality sensor 112 is mounted in the receiving groove 152 from the inside of the inner frame 125, and then the fixing cover 127 is mounted on the mounting base 15 from the inside of the inner frame 125. In the embodiments of this application, the installation method of the fixing cover 127 and the mounting base 15 is not limited. For example, it can be fixed by screws, snap-fit ​​connection, magnetic installation, etc.

[0136] refer to Figure 4 and Figure 16 In some embodiments, the air quality sensor 112 is connected to a second wiring harness 1121, and the fixing cover 127 has a fourth wire harness structure 1271 for constraining the second wiring harness 1121. The second wiring harness 1121 passes through the outer side of the inner frame 125 after being constrained by the fourth wire harness structure 1271.

[0137] In the above technical solution, the fourth wire structure 1271 constrains the second wire harness 1121, thereby making the wiring of the second wire harness 1121 more secure and reducing the shaking and wear of the second wire harness 1121, or the damage to the second wire harness 1121 caused by squeezing by components such as the heat exchanger 131.

[0138] refer to Figure 16In some embodiments, the air quality sensor 112 is connected to a second wiring harness 1121, which extends from the air quality sensor 112, bends downwards, and then extends upwards.

[0139] In the operating environment of the window air conditioner 100, water may come into contact with the air quality sensor 112 and its connected second wiring harness 1121 due to condensation, high air humidity, or accidental water spillage. The second wiring harness 1121 extends from the air quality sensor 112, bends downwards, and then extends upwards, forming a U-shaped structure. When water flows along the surface of the second wiring harness 1121, it drips downwards at the bend due to gravity, thereby reducing the risk of water entering the air quality sensor 112.

[0140] For example, such as Figure 6 and Figure 16 As shown, the air quality sensor 112 is connected to a second wiring harness 1121. The second wiring harness 1121 extends from the air quality sensor 112, bends downwards, and then extends upwards from the side of the fixing cover 127 away from the inner frame 125. The fourth wiring structure 1271 on the fixing cover 127 constrains the second wiring harness 1121, allowing it to extend upwards. (Refer to...) Figures 8-10 A refrigerant connection pipe 132 is provided on the side of the heat exchanger 131 near the inner frame 125. The fourth wire harness structure 1271 can effectively isolate the second wire harness 1121 from the refrigerant connection pipe 132 around the second wire harness 1121, preventing the refrigerant connection pipe 132 from vibrating and rubbing against the second wire harness 1121 with the compressor, etc., which would cause damage to the insulation layer of the second wire harness 1121 and ensure stable signal transmission of the air quality sensor 112. At the same time, it reduces the possibility of thermal damage to the second wire harness 1121 caused by the refrigerant connection pipe 132 when transporting hot refrigerant, thus preventing the second wire harness 1121 from aging rapidly.

[0141] refer to Figure 15 and Figure 16 The fourth wire harness structure 1271 constrains the second wire harness 1121 to extend upward to the through hole 1252 provided on the inner frame 125. The second wire harness 1121 passes through the wire hole 1232 to the outside of the inner frame 125. The third wire harness structure 1251 constrains the second wire harness 1121. The second wire harness 1121 mates with the second mating wire harness 172 on the outside of the inner frame 125. The second mating terminal 174 formed by the mating is fixed on the second terminal fixing buckle 1253 on the outer wall of the inner frame 125. The third wire harness structure 1251 is lower than the through hole 1252, and the second terminal fixing buckle 1253 is higher than the third wire harness structure 1251, thereby preventing water from entering the air quality sensor 112 along the second wire harness 1121.

[0142] In some embodiments, the indoor unit 1 includes an air purification component, which is an electrically powered component. Therefore, based on the detection data from the air quality sensor 112, the air purification component can be controlled to improve indoor air quality, providing users with a healthy and comfortable indoor environment. Exemplarily, the air purification component can be located in the air intake area 122a and includes a high-efficiency particulate air (HEPA) filter and an electrically powered vent. When the concentration of indoor air pollutants is detected to exceed a predetermined value, the electrically powered vent is opened to allow indoor air to pass through the HEPA filter, enhancing air filtration and removing indoor air pollutants.

[0143] refer to Figure 2 In some embodiments, the humidity sensor 111 is connected to a first wiring harness 1111, and the air quality sensor 112 is connected to a second wiring harness 1121. Both the first wiring harness 1111 and the second wiring harness 1121 extend to the same side of the indoor unit 1.

[0144] In the above technical solution, the wiring harnesses of humidity sensor 111 and air quality sensor 112 are extended to the same side of the indoor unit 1, such as extending to the left or right side, and are connected to the output wiring harnesses of the display component, such as the first pair of wiring harnesses 171 and the second pair of wiring harnesses 172, instead of being connected inside the indoor unit 1. This reduces the number of wiring harnesses arranged inside the indoor unit 1, reduces the mutual tangling and interference between wiring harnesses, and eliminates the need for complex wiring and connection operations inside the confined indoor unit 1, thus improving assembly efficiency. In addition, the unified wiring harness connection position makes it easy for installers to find the wiring harness connection points during installation and maintenance. During installation, the connection between the sensor wiring harness and the paired wiring harness can be completed quickly and accurately, improving installation efficiency. During maintenance, it is also easier to inspect, replace, or repair the sensor wiring harness, making it easier to troubleshoot the cause of sensor failure.

[0145] In some embodiments, the indoor unit 1 includes a front frame 121 and a ventilation and heat exchange component 13 housed within the front frame 121. A humidity sensor 111 and an air quality sensor 112 are both mounted on the front frame 121. For example, the front frame 121 may have multiple frame plates (e.g., an upper frame, a front frame, a rear frame 121a, and two side frames 121b), and is in the form of a frame body that is fitted over the ventilation and heat exchange component 13.

[0146] Therefore, by integrating the humidity sensor 111 and the air quality sensor 112 onto the frame 121 that covers the ventilation and heat exchange component 13, the installation of the humidity sensor 111 and the air quality sensor 112 is facilitated. For example, the humidity sensor 111 and the air quality sensor 112 can be pre-installed on the frame 121, and then the frame 121 can be fitted onto the ventilation and heat exchange component 13, thereby improving assembly convenience. Alternatively, the frame 121 can be fitted onto the ventilation and heat exchange component 13 first, and then the humidity sensor 111 and the air quality sensor 112 can be installed on the frame 121.

[0147] In some embodiments, the side of the indoor unit 1 facing the outdoor unit 2 is the rear side, and the side of the indoor unit 1 away from the outdoor unit 2 is the front side. The rear side of the indoor unit 1 has an air intake area 122a. The front frame 121 includes a rear frame 121a located behind the ventilation and heat exchange component 13, and a side frame 121b located on the left or right side of the ventilation and heat exchange component 13. The humidity sensor 111 is mounted on the rear frame 121a, and the air quality sensor 112 is mounted on the side frame 121b. Thus, the positions of the humidity sensor 111 and the air quality sensor 112 are convenient for information collection, and their installation does not affect each other.

[0148] In some embodiments, the humidity sensor 111 is connected to a first wiring harness 1111, and the air quality sensor 112 is connected to a second wiring harness 1121. Both the first wiring harness 1111 and the second wiring harness 1121 extend to the outside of the side frame 121b. This unifies the wiring harnesses to the same side, making it easier for installers to locate the wiring harness connection points during installation and maintenance. During installation, the sensor wiring harness can be quickly and accurately connected to its counterpart, improving installation efficiency.
