[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The HVAC system includes an indoor unit and an outdoor unit. Sensors can be installed on the indoor unit to realize detection functions. For example, the human sensing function in the HVAC system is generally realized through a human body sensor. The types of human body sensors generally include infrared sensors, radar sensors, etc. The human body sensor can use the temperature field within the detection range to detect the number of human bodies, human body positions and other information within the identification range, thereby intelligently, conveniently and energy-savingly controlling the operation mode of the HVAC system and providing users with humanized energy-saving control. At the same time, by setting a human body sensor on the indoor unit, the temperature of multiple areas can be detected without the need for a motor to drive the sensor for scanning.

[0028] Among them, the human sensing function means that when a human body moves within the detection range of the human body sensor, it can be detected by the human body sensor and send a detection signal to the relevant controller. The human sensing function is an optional function, and the indoor unit is not equipped with this function when it leaves the factory. If this function is required, it is necessary to open a separate hole in the indoor unit to install the human body sensor, which will make the subsequent installation steps of the human body sensor cumbersome and unsightly. Based on this, the embodiment of the present application provides a display component 1 that can be used in the indoor unit of an air conditioner, and a sensor can be integrated into the display component 1 of the indoor unit of the air conditioner, which is convenient for the installation of the sensor on the indoor unit of the air conditioner.

[0029] See also Figure 1 A display assembly 1 according to an embodiment of the present application includes a circuit board 10 , a lampshade 20 , a light-emitting element (not shown in the figure) and a sensor 30 .

[0030] The lampshade 20 is connected to the circuit board 10 . The lampshade 20 includes a cover body 21 and a base body 22 . The cover body 21 is connected to the base body 22 . The light emitting element is electrically connected to the circuit board 10 and is disposed on the cover body 21 .

[0031] The light emitted by the light emitting element can be emitted through the cover body 21, and a font frame such as temperature and mode can be set on the cover body 21. The light emitting element emits light, and then part of the light is emitted through the font frame on the cover body 21, so that it can be used to display the temperature or mode of the air conditioner indoor unit. The cover body 21 and the base body 22 can be an integrated structure to facilitate the installation of the lampshade 20 on the circuit board 10.

[0032] The sensor 30 is connected to the base portion 22 , and the sensor 30 is electrically connected to the circuit board 10 .

[0033] Specifically, the sensor 30 is installed on the base 22, that is, the sensor 30 is integrated with the lampshade 20, so that the sensor 30 and the lampshade 20 can be installed on the circuit board 10 simultaneously, reducing the steps of installing the sensor 30 later. That is to say, in the embodiment of the present application, the lampshade 20 and the sensor 30 are installed together, and after the detection function of the air-conditioning indoor unit is selected, the air-conditioning indoor unit can install the sensor 30 and the lampshade 20 together on the circuit board 10 when it leaves the factory, without the need to install the sensor 30 separately on the air-conditioning indoor unit later, thereby improving the installation efficiency. Among them, the embodiment of the present application does not specifically limit the connection method between the sensor 30 and the base 22. For example, the sensor 30 and the base 22 can be connected by means of snap connection, screw connection or bonding.

[0034] It should be noted that, in this embodiment, a seat portion 22 is provided on the lampshade 20, and the sensor 30 is installed on the seat portion 22, that is, the sensor 30 can be compatible with the lampshade 20, thereby making the installation of the sensor 30 more convenient and quick, improving the installation efficiency, and also reducing the number of circuit boards 10 required for the subsequent installation of the sensor 30.

[0035] At the same time, if the installation position of the sensor 30 is uncertain, the length of the conductive wire reserved on the sensor 30 will also be uncertain. In the present embodiment, the installation position of the sensor 30 on the lampshade 20 and the circuit board 10 is fixed. Based on this, the terminal on the circuit board 10 for electrically connecting with the sensor 30 can be set at a fixed position. When the sensor 30 is installed on the seat body 22, the conductive part on the sensor 30 can be directly electrically connected to the terminal of the circuit board 10, thereby making the conductive part structure on the sensor 30 uniformly set without having to be reserved according to the different installation positions of the sensor 30. Exemplarily, a connecting line is provided on the sensor 30, and the circuit board 10 includes a connecting point. When the sensor 30 is installed on the seat body 22, the connecting line can be electrically connected to the connecting point. At this time, the length of the connecting line can correspond to the distance from the sensor 30 to the connecting point, so as to reserve the line length of the sensor 30 in advance; or, a contact is provided on the sensor 30, and the circuit board 10 includes a connecting terminal. The connecting terminal is provided on the seat body 22. When the sensor 30 is installed on the seat body 22, the contact can contact the connecting terminal for conductivity, thereby making it more convenient to electrically connect the sensor 30 to the circuit board 10.

[0036] For further information, please see Figure 1 In some embodiments of the present application, the sensor 30 is clamped and fixed by the seat body 22 to facilitate the installation and removal of the sensor 30.

[0037] In some embodiments, the seat portion 22 may include a plurality of elastic arms, and the plurality of elastic arms together form a circular, square or irregular shaped accommodating cavity, in which the sensor 30 may be disposed. When the sensor 30 is installed, an external force is applied to the sensor 30, and the sensor 30 exerts a force on the elastic arm, thereby causing the elastic arm to deform. Subsequently, the sensor 30 enters the accommodating cavity under the action of the external force, and the elastic arm loses the external force, and the elastic arm is released from the deformation and returns to its original state. At this time, the elastic arm can prevent the sensor 30 from leaving the accommodating cavity, thereby clamping the sensor 30 in the accommodating cavity. Of course, the seat portion 22 and the sensor 30 may also be connected by other clamping methods, which will be described in detail below.

[0038] Please continue to see Figure 1 In some embodiments of the present application, the seat body 22 includes a mounting groove 24 and a limiting structure 25. The limiting structure 25 is arranged on the side of the mounting groove 24. The sensor 30 is arranged in the mounting groove 24. The mounting groove 24 provides a setting base and installation space for the sensor 30 to protect the sensor 30 and reduce the interference between the sensor 30 and external parts.

[0039] The limiting structure 25 is used to limit the sensor 30 in the installation slot 24, which can not only prevent the sensor 30 from being separated from the installation slot 24, but also reduce the shaking of the sensor 30 in the installation slot 24. The installation slot 24 and the limiting structure 25 can be an integrated structure to improve the clamping strength of the seat body 22.

[0040] Exemplarily, the installation slot 24 has an entrance and exit communicating with the slot space, and the sensor 30 can enter and exit the slot space of the installation slot 24 through the entrance and exit. The limiting structure 25 is movably connected to the mouth wall of the entrance and exit, and the sensor 30 has a moving track from the outside of the installation slot 24 through the entrance and exit to the slot space. When the sensor 30 is installed, the limiting structure 25 moves relative to the installation slot 24 so that the limiting structure 25 avoids the moving track of the sensor 30, thereby removing the obstruction to the sensor 30, so that the sensor 30 can smoothly enter the slot space of the installation slot 24; after the installation of the sensor 30 is completed, the limiting structure 25 is moved again relative to the installation slot 24 so that the limiting structure 25 is located on the moving track of the sensor 30 to block the movement of the sensor 30, thereby achieving the limiting of the sensor 30. Among them, the limiting structure 25 and the mouth wall of the entrance and exit can be rotatably connected or slidably connected, which can be selected according to actual conditions.

[0041] For further information, see Figure 1-Figure 2In some embodiments of the present application, the installation slot 24 has a first opening 241, and the sensor 30 enters the installation slot 24 through the first opening 241; the limiting structure 25 includes a first limiting member 251 arranged at the first opening 241, one end of the first limiting member 251 is connected to the mouth wall of the first opening 241, and the other end of the first limiting member 251 extends obliquely in a direction away from the first opening 241, and the first limiting member 251 has a guiding slope 2511. When the sensor 30 is installed, the sensor 30 slides into the installation slot 24 along the guiding slope 2511 at the first opening 241. At this time, the guiding slope 2511 can guide the movement of the sensor 30, thereby facilitating the installation of the sensor 30.

[0042] Among them, this embodiment does not limit the specific setting position of the first opening 241. For example, the first opening 241 can be located on the side of the mounting groove 24 away from the circuit board 10, that is, the first opening 241 is arranged opposite to the bottom wall of the mounting groove 24; for another example, the first opening 241 can be located on the side wall of the mounting groove 24.

[0043] See also Figure 3-Figure 4 In some embodiments of the present application, a second opening 242 is formed on a side of the mounting slot 24 away from the circuit board 10, and the limiting structure 25 includes a second limiting member 252. The second limiting member 252 is located at the second opening 242 and connected to the mouth wall of the second opening 242. The second limiting member 252 is used to prevent the sensor 30 from sliding out of the second opening 242, thereby preventing the sensor 30 from detaching from the mounting slot 24 from the second opening 242.

[0044] It should be noted that the sensor 30 has a first surface, and a plurality of electronic components are protruding from the first surface. When the sensor 30 is set in the mounting groove 24, the first surface faces the second opening 242. Since the second limiting member 252 is connected to the mouth wall of the second opening 242, the second limiting member 252 is located at the edge of the first surface, that is, the second limiting member 252 blocks the edge of the first surface to limit the sensor 30 at the second opening 242. At the same time, the plurality of electronic components protruding from the first surface can extend out of the mounting groove 24 through the first opening 241. On the one hand, it can reduce the collision of electronic components in the mounting groove 24, and on the other hand, it also enables the emitter and receiver on the sensor 30 to detect external conditions.

[0045] In some embodiments, the second limiting member 252 is movably connected to the mouth wall of the second opening 242, and the sensor 30 has a moving trajectory from the outside of the installation slot body 24 through the second opening 242 to the space inside the slot. When the sensor 30 is installed, the second limiting member 252 can move relative to the installation slot body 24 so that the second limiting member 252 avoids the moving trajectory of the sensor 30, so that the sensor 30 can smoothly enter the slot space of the installation slot body 24; after the installation of the sensor 30 is completed, the second limiting member 252 is moved again relative to the installation slot body 24 so that the second limiting member 252 is located on the moving trajectory of the sensor 30 to prevent the sensor 30 from sliding out of the second opening 242, thereby limiting the sensor 30 at the second opening 242.

[0046] See also Figure 3 A plurality of second limiting members 252 are provided, and the plurality of second limiting members 252 are spaced apart and arranged on the wall of the second opening 242 , so as to further enhance the limiting effect of the second limiting member 252 on the sensor 30 .

[0047] In some embodiments, the second limiting member 252 can be a limiting block, which is arranged on the mouth wall of the second opening 242 and contacts the edge of the sensor 30 to provide limiting for the sensor 30; the second limiting member 252 can also be a baffle, and the two ends of the baffle are respectively connected to the mouth walls on the opposite sides of the second opening 242, and multiple baffles are arranged at intervals to provide a more secure limiting effect for the sensor 30.

[0048] See also Figure 3-Figure 4 In some embodiments of the present application, a boss 243 is provided on one side of the mounting groove 24 close to the circuit board 10, and the sensor 30 is mounted on the boss 243, thereby increasing the height of the sensor 30 in the mounting groove 24. That is, when the lampshade 20 is mounted on the circuit board 10, the distance between the sensor 30 and the circuit board 10 increases. When the display assembly 1 is installed on the air-conditioning indoor unit, the sensor 30 will also be closer to the outside of the air-conditioning indoor unit, thereby making it easier for the sensor 30 to detect signals from the outside of the air-conditioning.

[0049] The boss 243 is disposed on the bottom wall of the mounting groove 24. In some embodiments, the boss 243 can be disposed along the peripheral side wall of the mounting groove 24 and abut against the edge of the sensor 30 to provide mounting support for the sensor 30, and the middle part of the sensor 30 is spaced from the bottom wall of the mounting groove 24 to reduce the contact area between the sensor 30 and the side wall of the mounting groove 24, thereby reducing the possibility of the sensor 30 being bumped in the mounting groove 24. Of course, the specific location of the boss 243 can also be in the middle part or other parts of the bottom wall of the mounting groove 24, which can be set according to actual conditions.

[0050] See also Figure 1 and Figure 3 In some embodiments of the present application, a snap-fit ​​structure 11 is provided on the circuit board 10, and the lampshade 20 is fixed to the circuit board 10 through the snap-fit ​​structure 11, so that the installation and removal of the lampshade 20 are more convenient.

[0051] Specifically, the buckle structure 11 can be buckled with the cover body 21, or the buckle structure 11 can also be buckled with the base body 22. The buckle structure 11 can be an elastic structure, and the lampshade 20 is subjected to an external force, which causes the buckle structure 11 to deform, and the lampshade 20 is pressed into the buckle structure 11, thereby making the buckle structure 11 and the lampshade 20 buckle; of course, the buckle structure 11 can also be other types of structures, which are not specifically limited here.

[0052] In a second aspect, an embodiment of the present application further provides an air-conditioning indoor unit, comprising a main body (not shown in the figure) and a display component 1 as described in any of the above embodiments, wherein the display component 1 is disposed in the main body.

[0053] Furthermore, in some embodiments of the present application, the main body includes a casing and a panel that are connected to each other. The casing is used to be installed in a wall or a ceiling. The panel is detachably connected to the casing, and the panel faces the interior of the room. A display port is provided on the panel, and the display port connects the interior and exterior of the panel, so that components arranged inside the panel can be connected to the outside through the display port.

[0054] The circuit board 10 is arranged in the housing, the lampshade 20 is located on the side of the circuit board 10 facing the panel, the sensor 30 includes an emitter, the lampshade 20 and the emitter are connected to the outside through the display port, the light emitted by the light-emitting element can be displayed to the user through the display port, and the emitter of the sensor 30 faces outside the display port, so that the sensor 30 can detect the signal outside the indoor unit of the air conditioner. Among them, the sensor 30 can also include a receiving electrode, which also faces outside the display port, so as to receive the detection signal transmitted back.

[0055] It should be noted that the circuit board 10 is arranged on the side of the housing close to the panel, and the circuit board 10 has a control module, which can be used to control the light emission of the light-emitting element and can also be used to receive the detection signal of the sensor 30, so as to control the specific working conditions of the air conditioner indoor unit according to the detection signal. The panel is also provided with an air outlet and a grille, and the grille is arranged at the air outlet to guide the air outlet of the air conditioner indoor unit, and the display port is arranged at a distance from the air outlet.

[0056] On the third aspect, the embodiment of the present application also provides a HVAC system (not shown in the figure), which includes but is not limited to air conditioning, multi-split units, heat pumps and other systems for heating or cooling.
