Description

Technical Field

[0001] This utility model relates to the field of wall-mounted air conditioning technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] Household air conditioning units can be divided into two types based on their structure: modular air conditioners and split-type air conditioners. Among them, the most common types of split-type air conditioners are floor-standing and wall-mounted air conditioners. Wall-mounted air conditioners are widely popular because of their compact structure and ability to save floor space.

[0003] In related technologies, traditional human sensors are clipped onto the control box, with a corresponding sensor hole on the outer casing. After the casing is installed, the sensor head protrudes from the hole. Due to deviations in casing length and installation, coupled with the different positioning references of the human sensor and the casing, the hole in the casing often deviates from the sensor head, causing part of the sensor head to be blocked, thus affecting the detection range. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a wall-mounted air conditioner indoor unit in which the positioning reference of both the human sensor and the human sensor cover is the outer cover. The positioning reference of the two is the same, which makes the positioning accuracy high and avoids the human sensor head being blocked due to positional deviation between the human sensor head and the human sensor hole.

[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-10 This invention describes a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. The wall-mounted air conditioner includes a wall-mounted indoor unit, which is installed indoors and used for heat exchange with the indoor environment.

[0021] like Figures 1-10 As shown, the wall-mounted air conditioner indoor unit 1000 includes: a casing, a heat exchanger, a fan, and a human sensor 2. The casing is installed indoors and forms the overall appearance of the wall-mounted air conditioner indoor unit 1000.

[0022] refer to Figure 1 As shown, the casing is roughly rectangular in shape. The casing has a top and a bottom, which are opposite each other in the height direction (vertical direction). The left and right sides of the casing are opposite each other in the length direction (horizontal direction), and the front and rear sides of the casing are opposite each other in the thickness direction (front-back direction).

[0023] The casing is located at the top of the room or in the upper space of the room, with the front of the casing facing the user and the rear of the casing facing the wall, making it suitable for connection with the wall.

[0024] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.

[0025] refer to Figure 1 As shown, the housing may include an outer cover 1 and a front panel. The outer cover 1 has an air inlet 11 and an air outlet 12. The outer cover 1 is generally in the shape of a cuboid frame, with a frame opening on the front side. The front panel is located on the front side of the outer cover 1. The front panel constitutes the front appearance of the wall-mounted air conditioner indoor unit 1000.

[0026] The outer cover 1 is connected to the front panel to form the casing.

[0027] The outer casing 1 has a heat exchange air duct inside. The heat exchange air duct is used to house and fix various components in the indoor unit of the air conditioner, which can prevent foreign objects from colliding with the various components inside the outer casing 1, thereby improving the reliability of the indoor unit of the air conditioner during transportation or installation.

[0028] The outer casing 1 has an air inlet 11. The air inlet 11 is connected to the heat exchange duct and serves as an inlet for external air to flow into the casing, allowing indoor air to enter the heat exchange duct through the air inlet 11.

[0029] The outer casing 1 has an air outlet 12. The air outlet 12 is connected to the heat exchange air duct and serves as the outlet for the heat exchange airflow inside the casing, allowing the airflow inside the heat exchange air duct to flow out through the air outlet 12.

[0030] The air inlet 11 can be located at the top of the outer casing 1. The air outlet 12 can be located at the bottom of the outer casing 1 and near the front side of the outer casing 1, that is, the air outlet 12 is located at the bottom front side of the outer casing 1. In this embodiment, when the wall-mounted air conditioner indoor unit 1000 is working, the wall-mounted air conditioner indoor unit 1000 takes in air from the top and exits air to the front, which is convenient for installation.

[0031] The air outlet 12 can be elongated and can extend along the length of the casing, which improves the aesthetics of the wall-mounted air conditioner indoor unit 1000.

[0032] In some embodiments of this application, the housing may also include a base that forms the rear side of the wall-mounted air conditioner indoor unit 1000 and is adapted to be mounted on a wall.

[0033] The outer cover 1 has an open rear side, and is placed on the front side of the base and connected to the base. A heat exchange air duct is defined between the outer cover 1 and the base. The outer cover 1, the base and the front panel together form the housing.

[0034] In some embodiments of this application, the wall-mounted air conditioner indoor unit 1000 may include a heat exchanger. The heat exchanger extends along the length of the casing and is disposed inside the outer cover 1 for heat exchange with the airflow inside the casing.

[0035] The heat exchanger is located between the air inlet 11 and the air outlet 12 to exchange heat with the air entering from the air inlet 11, and then exhaust it to the room from the air outlet 12.

[0036] In some embodiments of this application, the wall-mounted air conditioner indoor unit 1000 may include a fan. The fan is disposed inside the outer casing 1, and the axial direction of the fan extends along the length of the casing. It is used to drive indoor air outside the casing to enter the heat exchange duct inside the casing through the air inlet 11. The fan drives the air in the heat exchange duct to flow along the air inlet 11 toward the air outlet 12.

[0037] The fan is located below the heat exchanger. The heat exchanger can be located inside the air inlet 11. The fan can be located on the side of the heat exchanger away from the air inlet 11. That is, in the airflow direction within the casing, the fan is downstream of the heat exchanger.

[0038] When the indoor unit 1000 of the wall-mounted air conditioner is running, indoor air enters the outer casing 1 from the air inlet 11 under the operation of the fan. The indoor air in the heat exchange duct flows through the heat exchanger for heat exchange. The heat exchanged air is discharged to the outside of the room from the air outlet 12, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0039] Continue to refer to Figures 1-4 As shown, the human sensor 2 is located on the front side of the outer cover 1. The human sensor 2 includes a human sensor 21 and a human sensor cover 22, with the human sensor cover 22 located on the front side of the human sensor 21. The human sensor cover 22 is fixedly connected to the outer cover 1, and the human sensor head 211 of the human sensor 21 is exposed through the opening of the human sensor cover 22.

[0040] Specifically, the human sensor 21 is installed on the rear side of the human sensor cover 22, with its sensor head 211 exposed through an opening in the cover 22, used to acquire the user's human body information. The exposed portion of the human sensor 21 is minimal, having little impact on the appearance of the wall-mounted air conditioner indoor unit 1000. The human body information includes the user's body surface temperature, body position information, and the distance between the body and the wall-mounted air conditioner indoor unit 1000.

[0041] In some embodiments, the human sensor 21 may include a human body temperature detection module and an infrared detection sensing module. The human body temperature detection module is used to detect the surface temperature of the human body of indoor users. The infrared detection sensing module is used to detect the number of users indoors, obtain the position of each human body, and sense the distance between the human body and itself. Detecting the number and position of human bodies using infrared sensors or other sensors is well known to those skilled in the art, and its specific principles will not be detailed here. The human body temperature detection module can detect the surface temperature of the human body of indoor users. Sensing human body temperature using infrared radiation is also known in the art, and its specific principles will not be detailed here.

[0042] The human sensor cover 22 is placed on the front side of the human sensor 21. The human sensor cover 22 is positioned and installed with the outer cover 1, which makes the positioning accuracy high. This avoids the human sensor head 211 being blocked due to positional deviation between the human sensor head 211 and the opening, thus improving the detection accuracy.

[0043] Compared to having a human sensor hole on the outer cover 1, the holes on the outer cover 1 often deviate from the human sensor head 211 due to deviations in the length and installation of the outer cover 1, as well as the different positioning references between the human sensor device 2 and the outer cover 1, resulting in partial obstruction of the human sensor head 211. This application improves the positioning accuracy of the human sensor device 2 by separately setting a human sensor cover 22 and positioning it with the outer cover 1.

[0044] In some embodiments of this application, the front panel can be movably disposed on the front side of the outer cover 1. When the front panel is in the closed position, the front panel covers the front side of the outer cover 1 and blocks the human sensor 2. When the front panel is in the open position, the front panel opens the front side of the outer cover 1, so that the human sensor cover 22 can be exposed and human information can be obtained through the human sensor head 211 at the opening.

[0045] refer to Figure 3 and Figure 4 As shown, the human sensor 21 includes a human sensing plate 212, and a human sensing head 211 is mounted on the front of the human sensing plate 212. The human sensing head 211 is the core sensing part of the human sensor 21, mainly comprising a pyroelectric infrared sensor element and a Fresnel lens. The Fresnel lens is responsible for focusing infrared radiation of a specific wavelength emitted by the human body onto the sensor element. When a moving heat source (such as a person) enters its detection area, the sensor element will generate a weak electrical signal due to receiving the changing infrared radiation.

[0046] The human motion sensor board 212 is a PCB board with integrated control circuitry. It receives weak analog signals from the human motion sensor 211, and after a series of processing steps such as signal amplification, filtering, and comparison, it determines whether the signal is a valid human movement signal. Once confirmed, it outputs a control signal (such as a high / low level signal) to the control box.

[0047] and combined Figures 5-7 As shown, the outer cover 1 has a receiving cavity 13 with an opening facing the human detection cover 22, and the human detection sensor 21 is housed in the receiving cavity 13. By placing the human detection sensor 21 in the receiving cavity 13 formed by the outer cover 1, the positioning reference of the human detection sensor 21 is the receiving cavity 13 of the outer cover 1. Compared with other positioning structures such as positioning posts and positioning holes, the positioning accuracy of the receiving cavity 13 is higher, effectively avoiding the positional deviation between the human detection head 211 and the light-transmitting hole that would block the human detection head 211, thereby improving the detection accuracy.

[0048] The receiving cavity 13 is equipped with a connecting structure 14, through which the human sensor plate 212 is fixed. Specifically, the entire human sensor 21 is placed inside the receiving cavity 13, and the human sensor plate 212 is fixed by the connecting structure 14 inside the receiving cavity 13, so that the human sensor 21 is firmly installed inside the receiving cavity 13 of the outer cover 1. Then, the human sensor cover 22 is fixed to the outer cover 1 to cover the human sensor plate 212 and related parts of the outer cover 1 for a certain aesthetic purpose.

[0049] This application forms a receiving cavity 13 on the outer cover 1 to install the human sensor 21. Compared with the solution of setting a human sensor box, placing the human sensor 21 in the human sensor box and positioning the human sensor box and the outer cover 1, this application sets a receiving cavity 13 on the outer cover 1, which eliminates the positioning installation between the human sensor box and the outer cover 1. The structure is simple and easy to install, and the assembly efficiency is improved.

[0050] Therefore, the positioning reference for both the human sensor 21 and the human sensor cover 22 is the outer cover 1. The identical positioning reference ensures high positioning accuracy and prevents the light-blocking hole from obstructing the human sensor 211 due to positional deviation between the human sensor head 211 and the light-transmitting hole. Furthermore, the positioning reference for the human sensor 21 is the receiving cavity 13 of the outer cover 1. Compared to other positioning structures such as positioning posts and positioning holes, the receiving cavity 13 offers higher positioning accuracy, a simpler installation structure, and easier installation, thus effectively guaranteeing the detection accuracy of the human sensor 21.

[0051] In some embodiments of this application, the connecting structure 14 includes elastic buckles 141 respectively provided on the opposite two cavity walls of the receiving cavity 13, and the human sensor plate 212 is snapped to the bottom of the receiving cavity 13 through the elastic buckles 141.

[0052] refer to Figures 5-7 As shown, when installing the human sensor 21 onto the outer cover 1, the human sensor 21 is pressed into the receiving cavity 13, and the human sensor plate 212 is directly assembled into the receiving cavity 13 of the outer cover 1 via the elastic buckle 141. The assembly is simple and the positioning is reliable. The edge of the human sensor plate 212 directly engages with the elastic buckle 141, eliminating the need for additional buckle structures.

[0053] In some embodiments of this application, a wire hole 15 is provided in the receiving cavity 13, and a wire buckle 16 is provided on one side of the outer cover 1 located on the human sensor plate 212 for the routing of the human sensor 21.

[0054] refer to Figures 5-7As shown, a wire hole 15 is provided on one side of the human sensor board 212 inside the receiving cavity 13 for wiring of the human sensor board 212. The outer cover 1 is also provided with a wire hook 16 for hanging the wire harness of the human sensor board 212 on it before passing to the main control board, so as to prevent the wire harness from being suspended inside the outer cover 1, thereby avoiding affecting the installation and operation of related components inside the outer cover 1.

[0055] In some embodiments of this application, the shape of the receiving cavity 13 matches that of the human sensor plate 212, and the bottom of the receiving cavity 13 is inclined so that the human sensor head 211 is tilted downward.

[0056] refer to Figures 5-7 As shown, the human sensor panel 212 is square in shape, and the receiving cavity 13 is also designed to be square, so that the human sensor panel 212 is confined within the receiving cavity 13, realizing the positioning and installation of the human sensor panel 212 and the outer cover 1. Furthermore, the bottom of the receiving cavity 13 is designed as a slope to match the detection angle of the human sensor head 211. With the human sensor 21 placed inside the receiving cavity 13 and the human sensor head 211 tilted downwards, it can obtain human information by looking towards the person below the wall-mounted air conditioner indoor unit 1000.

[0057] In some embodiments of this application, the portion of the receiving cavity 13 adjacent to its opening is flared, and the flared shape matches the shape of the human-sensing plate 212.

[0058] refer to Figures 5-7 As shown, the opening of the receiving cavity 13 is flared, which allows the human sensor 21 to smoothly enter the inside of the receiving cavity 13, reducing assembly difficulty and protecting sensitive components. Furthermore, the human sensor plate 212 is square, and the flared opening provides sufficient operating space between the perimeter of the human sensor plate 212 and the opening, facilitating installation.

[0059] In some embodiments of this application, an annular recess 221 is formed on the front of the human sensor cover 22. The annular recess 221 gradually expands from one end adjacent to the human sensor head 211 to the other end. The rear end of the annular recess 221 is accommodated in the opening, and the human sensor head 211 is disposed at the opening formed by the annular recess 221.

[0060] refer to Figure 3 , Figure 4 and Figure 8 As shown, the annular recess 221 on the front of the human sensor cover 22 gradually widens to match the detection angle of the human sensor head 211. Because the annular recess 221 is formed on the front of the human sensor cover 22, the back of the human sensor cover 22 protrudes rearward. After the human sensor cover 22 is fixed to the outer cover 1, the rear end of the annular recess 221 is positioned at the opening, so that the human sensor head 211 is located at the opening of the annular recess 221, as shown in the attached diagram. Figure 9 As shown, the installation structure between the human-sensing cover 22, the human-sensing sensor 21, and the outer cover 1 is compact and saves space.

[0061] In some embodiments of this application, a first snap-fit ​​structure 222 is provided on the rear side of the human-sensing cover 22, and a second snap-fit ​​structure is provided on the outer cover 1 to engage with the first snap-fit ​​structure 222.

[0062] This design requires precise alignment between the rear side of the human sensor cover 22 and the outer cover 1 during assembly for them to engage. This "positional constraint" directly prevents the human sensor cover 22 from shifting forward or backward or tilting left or right during assembly, ensuring that the relative positions of the human sensor cover 22 and the outer cover 1 are fixed. Furthermore, the "convex-concave fit" of the buckle creates a physical limit, further locking the connection posture between the human sensor cover 22 and the outer cover 1. The positioning accuracy is high, making it suitable for human sensor 21 with high installation accuracy requirements. Moreover, it eliminates the need for screws, bolts, or other auxiliary fasteners. Simply align the first buckle structure 222 on the rear side of the human sensor cover 22 with the second buckle structure on the outer cover 1, and engage the sensor by pressing. The assembly is simple and efficient.

[0063] Among them, the human-sensing cover 22 and the outer cover 1 are usually injection-molded plastic parts (such as ABS, PP), which have a certain degree of elasticity but weak rigidity. The first buckle structure 222 can use the elastic deformation of plastic to achieve "lock-and-unlock", avoiding the cracking of plastic parts caused by rigid connection (such as strong fastening); at the same time, the "flexible fit" of the buckle can buffer slight vibrations, reduce fatigue wear of plastic parts, and extend the service life of the overall structure.

[0064] In some embodiments of this application, the first snap-fit ​​structure 222 includes an elastic hook 2221 and a snap block 2222, which are disposed on opposite sides of the human-sensing cover 22. The second snap-fit ​​structure includes a snap hole 171 and a snap groove 172, with the elastic hook 2221 snapped into the snap hole 171 and the snap block 2222 snapped into the snap groove 172.

[0065] Specifically, the elastic hook 2221 and the locking hole 171, and the locking block 2222 and the locking groove 172 correspond to the opposite sides of the human sensor cover 22. During assembly, the structures on both sides must be aligned simultaneously to lock in place. This avoids the problem of "offset or tilt" during the assembly of the human sensor cover 22, ensuring the accurate relative position of the human sensor cover 22 and the outer cover 1, and reducing the deviation of the detection angle of the human sensor 21 due to assembly misalignment. Furthermore, the locking structures on both sides form a "two-way constraint": the elastic hook 2221 engages with the locking hole 171 through its own elastic deformation, providing a fastening force along the "locking insertion direction"; the locking block 2222 engages with the locking groove 172, providing a limiting force along the "perpendicular to the insertion direction". The combination of the two can resist external forces in multiple directions (such as vibration and slight impact), preventing the human sensor cover 22 from falling off or loosening during the movement of the air conditioner.

[0066] The sensor cover 22 is typically a thin-walled plastic component. The elastic hook 2221 utilizes the plastic's own elasticity to achieve "deformation-reset," preventing the sensor cover 22 from cracking due to rigid connections (such as screws). Simultaneously, the locking block 2222 is a rigid structure, compensating for potential "elastic fatigue" of the elastic hook 2221 after prolonged use, extending the overall structure's lifespan. Compared to screw connections, the snap-fit ​​structure requires no additional openings, allowing for more space for the sensors inside the sensor cover 22.

[0067] In some embodiments of this application, the front side of the outer cover 1 includes a first area 18 and a second area 19. The second area 19 is located below the first area 18. The second area 19 is provided with a mounting plate 20 integrally formed with the outer cover 1. The mounting plate 20 forms a receiving cavity 13. The human sensor plate 212 and the human sensor head 211 are fixed in the receiving cavity 13. The human sensor cover 22 is fixedly connected to the mounting plate 20.

[0068] like Figure 1 As shown, the front side of the outer cover 1 is divided into a first zone 18 and a second zone 19 located below the first zone 18. The second zone 19 has an air outlet 12 and a mounting plate 20, which is positioned and installed with the human sensor cover 22 and the human sensor plate 212 respectively. The mounting plate 20 is integrally formed with the outer cover 1, which improves the structure of the mounting plate 20 and the connection and support between the mounting plate 20 and the human sensor device 2.

[0069] In some embodiments of this application, the wall-mounted air conditioner indoor unit 1000 may include an air guide plate. The air guide plate is disposed in the second zone 19 and is rotatably connected to the outer casing 1, for closing and opening the air outlet 12. When the air outlet 12 is open, the air guide plate guides the heat exchange airflow.

[0070] The human sensor 2 is located on one side of the air guide plate along the lateral direction. For example... Figure 1In the illustrated embodiment, the human sensor 2 is positioned on the right side of the air guide plate along the lateral direction. Since the human sensor 2 (especially the infrared sensor) is sensitive to changes in ambient airflow and temperature, if it were positioned at the air outlet 12, the cold / hot air blown out by the air conditioner would directly flow over the sensor surface, causing the sensor to mistakenly interpret "airflow temperature change" as "human movement," or the infrared signal reception might be affected by airflow disturbances (such as blocking human infrared radiation). By positioning the human sensor 2 on one side of the air outlet 12, the problem of heat exchange airflow affecting the signal reception of the human sensor 21 is effectively avoided, improving the accuracy of the human information acquired by the human sensor 2.
