Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow rate of the air in a building or structure.

[0003] An air conditioner consists of an indoor unit and an outdoor unit. It regulates the indoor temperature by exchanging heat with the indoor air through a refrigerant that flows between the indoor and outdoor units.

[0004] In modern buildings, especially in well-sealed spaces such as office buildings and apartments, people spend long periods of time indoors where air circulation is poor, which can easily lead to a decline in indoor air quality. Therefore, it is necessary to equip indoor units with a fresh air function to introduce fresh outdoor air into the room. Although some indoor units have a fresh air function, the design of the fresh air outlet has many drawbacks. For example, the fresh air outlet is difficult to maintain and clean, affecting the quality of the fresh air output. In addition, the air volume of the fresh air outlet is limited, resulting in low air circulation efficiency. Utility Model Content

[0005] This application discloses an air conditioner that can reduce the difficulty of maintenance and cleaning of the fresh air outlet and improve air circulation efficiency.

[0006] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0007] Indoor unit, the indoor unit includes:

[0008] The main unit has an air outlet side facing the indoor space;

[0009] A flange, which is connected to the air outlet side of the main unit;

[0010] A panel is attached to the side of the flange away from the main unit by fasteners, and the panel is provided with a mounting port;

[0011] The fresh air duct component is connected to the flange and communicates with the mounting port;

[0012] A grille assembly is detachably mounted at the mounting port. The grille assembly is configured to cover the fasteners and allow fresh air from the fresh air duct to blow into the indoor space.

[0013] In this way, the grille assembly is detachably installed at the mounting port, facilitating disassembly, reducing maintenance difficulty, and effectively concealing fasteners, resulting in a cleaner and more streamlined appearance for the indoor unit.

[0014] This application also discloses an air conditioner, comprising:

[0015] Indoor unit, the indoor unit includes:

[0016] Fresh air system components;

[0017] A panel, the panel having a mounting port that communicates with the fresh air duct component; a grille assembly, detachably mounted at the mounting port;

[0018] The grille assembly includes:

[0019] A bottom shell, the bottom shell having a ventilation opening communicating with the mounting port;

[0020] A grille is installed on the bottom shell and is located on the side of the bottom shell facing the indoor space. The bottom shell and the grille form a ventilation cavity so that the fresh air passes through the vent, the ventilation cavity and the grille in sequence and is blown into the indoor space.

[0021] In this way, the vents on the bottom shell are connected to the fresh air duct. The size of the vents can be optimized according to the airflow output of the duct and the indoor ventilation requirements. Larger vents can receive more fresh air from the duct without increasing too much resistance. The ventilation cavity between the bottom shell and the grille acts as a buffer and expander. When fresh air enters the ventilation cavity from the vents, the ventilation cavity provides a space for air diffusion, allowing the air to be evenly distributed in this relatively wide area. The ventilation cavity evenly delivers the diffused air to various parts of the grille. Since the area of ​​the grille may cover the entire installation area or even a larger area, when the air in the ventilation cavity passes through the grille, it can make full use of the large area of ​​the grille to blow the air into the indoor space over a large area, effectively expanding the air outlet area, thereby increasing the fresh air output and improving the air circulation efficiency.

[0022] This application also discloses an air conditioner, wherein the grille assembly includes:

[0023] A first snap-fit ​​structure is configured to enable the grille to snap onto the bottom shell along a first direction, the first direction being parallel to the air outlet direction;

[0024] A second snap-fit ​​structure is configured to allow the grille to snap onto the mounting opening along the first direction.

[0025] In this way, the staff only needs to align the grating with the bottom shell or mounting port along the first direction and then apply a certain pressure to complete the snap-fit ​​operation. Compared with the traditional method that requires multiple screws or complex snap-fit ​​structures and has limited installation direction, this snap-fit ​​method along the first direction is simpler and faster, which can effectively improve assembly efficiency. When the grating needs to be maintained, cleaned or replaced, the grating can be removed from the bottom shell or mounting port by applying a certain external force in the opposite direction of installation.

[0026] In addition, the first snap-fit ​​structure snaps the grille to the bottom shell, and the second snap-fit ​​structure snaps the grille to the mounting port. This double snap-fit ​​structure ensures the stability of the grille from two different levels. After the first and second snap-fit ​​structures are snapped together, a certain pre-tightening force is formed. This pre-tightening force can make the grille fit tightly with the bottom shell and the mounting port. The tight fit not only enhances the stability of the connection, but also prevents gaps from forming at the connection point, avoiding air leakage or dust and other impurities entering due to gaps.

[0027] This application also discloses an air conditioner, wherein the first snap-fit ​​structure includes:

[0028] The first hook is located on the bottom shell;

[0029] A first slot is provided on the grille member. When the grille member is installed on the bottom shell, the first hook engages with the first slot.

[0030] This application also discloses an air conditioner, wherein the first snap-fit ​​structure includes:

[0031] The second hook is provided on the grille;

[0032] A first snap-fit ​​boss is provided on the bottom shell. When the grille is installed on the bottom shell, the second snap-fit ​​hook is snapped onto the first snap-fit ​​boss.

[0033] This application also discloses an air conditioner, the bottom casing of which includes:

[0034] The bottom wall is positioned facing the fresh air duct component;

[0035] The sidewall is connected to the bottom wall and extends along the thickness direction of the bottom wall;

[0036] The grille components include:

[0037] The grille panel is positioned facing the fresh air duct component;

[0038] The side panel is connected to the grille panel and to the side wall;

[0039] This application also discloses an air conditioner, wherein the first hook is disposed on the side wall and the first slot is disposed on the side plate.

[0040] Thus, simply bring the side plate of the grille close to the side wall of the bottom shell, align the first hook with the first slot, and then push the grille in the direction of airflow to complete the snap-fit. No additional complicated operations or tools are required, which improves installation efficiency. When the first hook and the first slot are engaged, the air pressure on the grille during airflow will be transmitted to the side wall through the side plate, effectively preventing the grille from separating from the bottom shell or becoming loose when subjected to airflow impact or other external forces (such as slight collisions or vibrations), thus ensuring the structural integrity of the grille assembly.

[0041] This application also discloses an air conditioner, wherein the second hook is disposed on the side plate and the first engaging protrusion is disposed on the side wall.

[0042] Thus, when the second hook engages with the first engagement boss, the grille is fixed in position in a plane perpendicular to the air outlet direction. The first engagement boss provides support and positioning for the second hook, preventing the grille from shifting horizontally. At the same time, due to the engagement structure between the second hook and the first engagement boss, the grille is also stably fixed in the air outlet direction, preventing the grille from moving back and forth due to the pressure generated by airflow.

[0043] This application also discloses an air conditioner, wherein the first hook and the second hook are both elastic hooks. During the process of installing the grille on the bottom shell, the first hook and the second hook are pressed by the side wall. When the grille is installed on the bottom shell, the first hook extends into the first slot and engages with the first slot, and the second hook approaches the first engagement protrusion and engages with the first engagement protrusion.

[0044] Thus, during the installation of the grille onto the bottom shell, the first and second hooks can be adaptively deformed by the side wall pressure, making the installation process more flexible. Even when there is a slight deviation in the alignment between the grille and the bottom shell, the first and second hooks can adjust their positions during the pressure process, ultimately allowing the first hook to smoothly extend into the first slot and the second hook to engage with the first engagement protrusion. The elastic hook provides a tighter engagement effect after engagement. When the second hook engages with the first engagement protrusion, its elastic restoring force causes the hook to tightly hold the first engagement protrusion, increasing the firmness of the engagement.

[0045] This application also discloses an air conditioner, the bottom casing of which includes:

[0046] The bottom wall is positioned facing the fresh air duct component;

[0047] The sidewall is connected to the bottom wall and extends along the thickness direction of the bottom wall;

[0048] The grille components include:

[0049] The grille panel is positioned facing the fresh air duct component;

[0050] The side panel is connected to the grille panel and to the side wall;

[0051] The second snap-fit ​​structure includes:

[0052] The second snap-fit ​​protrusion is disposed on the inner wall of the mounting port;

[0053] The third hook is provided on the side plate. When the grille is installed on the panel, the third hook engages with the second engagement protrusion.

[0054] Thus, the second snap-fit ​​protrusion is on the inner wall of the mounting opening, and the third snap-fit ​​hook is on the side plate of the grille. When the two are snapped together, the grille is fixed from multiple directions. In the vertical direction, the snap-fit ​​structure can withstand the weight of the grille itself and prevent it from sinking. In the horizontal direction, it restricts the translational movement of the grille, so that it will not easily shift when subjected to external forces (such as vibration caused by airflow, accidental collisions, etc.), ensuring the stability of the connection between the grille and the panel, thereby ensuring the stability of the entire indoor unit structure.

[0055] This application also discloses an air conditioner, wherein the third hook is an elastic hook. During the process of installing the grille into the mounting port, the third hook is pressed against the inner wall of the mounting port. When the grille is installed into the mounting port, the third hook approaches the second locking protrusion and engages with the second locking protrusion.

[0056] In this way, after the elastic hook engages with the second engagement boss, its elastic restoring force can ensure that a tight connection is formed between the third hook and the second engagement boss, making the fixing of the grille at the installation opening more stable and effectively resisting various external forces that may be encountered during use, such as pressure generated by air flow, vibration, and accidental collisions.

[0057] This application also discloses an air conditioner, wherein a detection port is provided on the bottom wall and the detection port is in communication with the ventilation cavity;

[0058] The indoor unit includes:

[0059] An air quality detection module is disposed on the side of the bottom wall away from the grille panel and located at the detection port. The air quality detection module is used to detect air quality.

[0060] By placing the air quality detection module at the detection port on the bottom wall, the fresh air about to be blown into the indoor space is directly detected, ensuring that the air sample detected is the air that the user actually breathes, so that the detection results can accurately reflect the real-time changes in indoor air quality.

[0061] This application also discloses an air conditioner, wherein the grille assembly includes:

[0062] Windbreak ribs are provided on the bottom wall and enclose the ventilation opening.

[0063] In this way, the airflow direction entering the ventilation cavity from the fresh air duct can be effectively guided. When fresh air enters the ventilation opening from the duct, if there are no wind deflectors, the air may spread in all directions, causing some air to form vortices or flow randomly in the ventilation cavity. However, the wind deflectors can guide the air in a specific direction, allowing it to enter the ventilation cavity along a more orderly path, thereby optimizing the initial airflow direction and improving the efficiency of air circulation.

[0064] This application also discloses an air conditioner, wherein a wiring port is provided on the flange, and the wiring port corresponds to the mounting port and the grille assembly along the air outlet direction;

[0065] The panel is equipped with a display module, which is electrically connected to the control module inside the host through the wiring port.

[0066] Thus, the wiring port on the flange provides a dedicated channel for wiring between the display module and the control module inside the main unit. Compared to situations where wires may need to bypass multiple components or pass through confined spaces without a wiring port, this simplifies the wiring process and improves assembly efficiency. Furthermore, when the indoor unit needs maintenance or repair, such as checking for problems with the wiring connection between the display module and the control module, the presence of the wiring port allows technicians to quickly locate and find the wiring. Through the wiring port, the connection status of the wires can be directly observed, facilitating the inspection, testing, and repair of the wiring. The design of the grille assembly corresponding to the wiring port and the mounting port allows the grille assembly to effectively conceal the wiring port and the wires inside it. When viewed from the front or side of the indoor unit, users cannot see messy wires, making the overall appearance of the equipment cleaner and more aesthetically pleasing.

[0067] This application also discloses an air conditioner, wherein a limiting member is provided at the wiring port, and the limiting member is used to limit the position of the wire connecting the display module and the control module in the host at the wiring port.

[0068] In this way, the limiting component provides a precise positioning function for the wires at the wiring port. When the wires connecting the display module and the control module pass through the wiring port, the limiting component can limit the position of each wire, so that they are arranged according to the predetermined path. This can prevent the wires from piling up messily near the wiring port, reduce unnecessary space occupation, achieve a more reasonable layout in a limited space, and improve the aesthetics of the entire device.

[0069] This application also discloses an air conditioner, wherein the indoor unit is fixed to the ceiling, and the indoor unit includes:

[0070] Two sets of decorative components are respectively connected to both ends of the indoor unit along the length direction, so that the indoor unit and the two sets of decorative components form a beam-like structure;

[0071] Each set of decorative components includes:

[0072] Front panel, the front panel and the front panel are located on the same side;

[0073] The rear panel is disposed opposite to the front panel;

[0074] A base plate, which is detachably connected between the lower end of the front plate and the lower end of the rear plate to cover the space between the front plate and the rear plate;

[0075] The fresh air duct is located outside the main unit and within the space formed by the front panel, rear panel, and bottom plate.

[0076] In this way, the fresh air duct is located outside the main unit and within the space enclosed by the decorative components, making it easier for maintenance personnel to access the duct. When regular maintenance of the fresh air duct is required, such as cleaning the inside of the duct, checking the tightness of the duct connections, or replacing aging duct components, there is no need to disassemble the complex indoor unit. Simply open the bottom plate of the decorative components to directly access the fresh air duct, reducing the difficulty and time cost of maintenance and improving the efficiency of maintenance work.

[0099] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0100] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0101] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0102] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0103] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components whose specific types and structures may be the same or different, and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0104] As mentioned in the background section, although some indoor units have a fresh air function, the design of the fresh air outlet has many drawbacks. For example, the fresh air outlet is difficult to maintain and clean, which affects the quality of the fresh air. In addition, the air volume of the fresh air outlet is limited, which cannot effectively improve indoor air quality.

[0105] To address the aforementioned issues, this application provides an air conditioner that reduces maintenance difficulty by detachably mounting a grille assembly on the panel at an installation port connected to the fresh air duct. The grille assembly includes a grille and a base shell, with the base shell and grille forming a ventilation cavity. This allows fresh air to sequentially pass through the vent, the ventilation cavity, and the grille before being blown into the indoor space. When fresh air enters the ventilation cavity from the vent, the ventilation cavity provides a space for air diffusion, allowing the air to be evenly distributed within this relatively wide area. This diffusion effect is similar to dispersing a concentrated airflow, effectively expanding the distribution range of the air before it enters the grille, thereby increasing the air volume and thus improving air circulation efficiency.

[0106] The following will describe specific embodiments and appendices. Figure 1-12 The technical solution of the air conditioner in this application will be further explained.

[0107] like Figure 1 As shown, the air conditioner 1 includes an indoor unit 10. The indoor unit 10 is an important component of the air conditioner 1 system, mainly responsible for regulating the air indoors, and it is usually rectangular in shape.

[0108] like Figure 2 The indoor unit 10 may include a main unit 11, which has an air outlet side facing the indoor space. The main unit 11 is the core part of the air conditioning system, and it contains key components of the indoor unit 10, such as an evaporator and a fan, which are responsible for cooling and heating the air. The cooled, heated or purified air is blown into the indoor space from the air outlet side to regulate the temperature of the indoor space.

[0109] like Figure 2 The indoor unit 10 may include a flange 12, which is connected to the air outlet side of the main unit 11. The flange 12 is typically connected between the main unit 11 and the panel 13.

[0110] like Figure 2 , Figure 3 as well as Figure 4As shown, the indoor unit 10 may include a panel 13, which is connected to the side of the flange 12 away from the main unit 11 by fasteners 14. The panel 13 has a mounting port 13a, and the fastener 14 is located at the mounting port 13a. The fastener 14 can be a screw, bolt, rivet, etc., and can be set close to the flange 12 so that the fastener 14 can better bear the tension and pressure between the panel 13 and the main unit 11, improve the stability of the connection, and reduce the protruding part on the surface of the panel 13, making the appearance of the indoor unit 10 more concise and beautiful.

[0111] like Figure 2 and Figure 5 As shown, the indoor unit 10 may also include a fresh air duct component 15, which is connected to the flange 12 and communicates with the mounting port 13a.

[0112] like Figures 1 to 3 As shown, the indoor unit 10 may also include a grille assembly 100, which is detachably disposed at the mounting port 13a. The grille assembly 100 is configured to block the fastener 14 and allow the fresh air delivered by the fresh air duct 15 to blow into the indoor space.

[0113] In this way, the main unit 11, flange 12, and panel 13 form a stable structure. The main unit 11 serves as the basic support, the flange 12 plays a connecting and transfer role on the air outlet side of the main unit 11, and the panel 13 is connected to the flange 12 through fasteners 14, so that the main unit 11 part of the entire indoor unit 10 is tightly connected.

[0114] The fresh air duct component 15 is connected to the flange 12 and communicates with the mounting port 13a. The stable connection structure between the flange 12, the main unit 11, and the panel 13 provides a stable channel for the delivery of fresh air, ensuring that the fresh air can be delivered from the duct under stable pressure and airflow conditions. The presence of the grille assembly 100 can adjust the flow direction of the fresh air to a certain extent, so that the fresh air is more evenly distributed when it blows into the indoor space, avoiding the situation of excessive or insufficient local wind speed, and further improving the comfort of the indoor air environment.

[0115] In addition, the grille assembly 100 is detachably installed at the mounting port 13a, which facilitates disassembly, reduces maintenance difficulty, and effectively conceals the fasteners 14, making the indoor unit 10 look more concise and neat.

[0116] In some possible embodiments, such as Figure 6 and Figure 7 As shown, the grille assembly 100 may include a bottom shell 110, which has a vent 1101 communicating with the mounting port 13a. In this embodiment, the vent 1101 may be configured as a pre-knock hole, which is broken during assembly to form the vent 1101.

[0117] like Figure 6 and Figure 8 As shown, the grille assembly 100 may also include a grille 120, which is installed on the bottom shell 110 and located on the side of the bottom shell 110 facing the indoor space. The bottom shell 110 and the grille 120 enclose a ventilation cavity so that fresh air passes through the ventilation opening 1101, the ventilation cavity and the grille 120 in sequence and blows into the indoor space.

[0118] Fresh air enters through the fresh air duct 15, passes through the mounting port 13a of the panel 13, and then sequentially passes through the ventilation port 1101 of the bottom shell 110, the ventilation cavity enclosed by the bottom shell 110 and the grille 120. Finally, it is blown into the indoor space by the grille 120, ensuring that air can be transported to the room in an orderly manner from the duct, reducing airflow turbulence and resistance, and improving ventilation efficiency.

[0119] The vent 1101 of the bottom shell 110 is connected to the fresh air duct component 15. The size of the vent 1101 can be optimized according to the air volume output of the duct and the indoor ventilation requirements. A larger vent 1101 can receive more fresh air from the duct without increasing too much resistance. The ventilation cavity between the bottom shell 110 and the grille component 120 plays a buffering and air diversion role. When fresh air enters the ventilation cavity from the vent 1101, the ventilation cavity provides a space for air diffusion, so that the air is evenly distributed in this relatively wide area. This diffusion effect is similar to dispersing the concentrated airflow, effectively expanding the distribution range of the air before entering the grille component 120.

[0120] The grille 120 consists of multiple strip-shaped or mesh-shaped ventilation sections with certain intervals between them. The grille 120 fits tightly with the ventilation cavity, which evenly delivers diffused air to various parts of the grille 120. Since the area of ​​the grille 120 may cover the entire installation port 13a area or a larger area, when the air in the ventilation cavity passes through the grille 120, it can make full use of the large area of ​​the grille 120 to blow the air into the indoor space over a large area, thereby effectively expanding the air outlet area, increasing the fresh air volume, and thus improving the air circulation efficiency.

[0121] In some possible embodiments, such as Figure 6 As shown, the grille assembly 100 may include a first snap-fit ​​structure 130, which is configured to enable the grille member 120 to snap onto the bottom shell 110 along a first direction, the first direction being parallel to the air outlet direction.

[0122] like Figure 7 As shown, the grille assembly 100 may further include a second snap-fit ​​structure 140, which is configured to enable the grille member 120 to snap into the mounting opening 13a in a first direction.

[0123] When installing the grating component 120, the operator only needs to align the grating component 120 with the bottom shell 110 or the mounting port 13a along the first direction, and then apply a certain pressure to complete the snap-fit ​​operation. Compared with the traditional method that requires multiple screws or complex snap-fit ​​structures and has limited installation direction, this snap-fit ​​method along the first direction is simpler and faster, and can effectively improve assembly efficiency. When the grating component 120 needs to be maintained, cleaned or replaced, the grating component 120 can be removed from the bottom shell 110 or the mounting port 13a by applying a certain external force in the opposite direction to the installation.

[0124] In addition, the first snap-fit ​​structure 130 snaps the grille 120 to the bottom shell 110, and the second snap-fit ​​structure 140 snaps the grille 120 to the mounting port 13a. This double snap-fit ​​structure ensures the stability of the grille 120 from two different levels. After the first snap-fit ​​structure 130 and the second snap-fit ​​structure 140 snap together, a certain pre-tightening force will be formed. This pre-tightening force can make the grille 120 fit tightly with the bottom shell 110 and the mounting port 13a. The tight fit not only enhances the stability of the connection, but also prevents gaps from forming at the connection point, avoiding air leakage or dust and other impurities entering due to gaps.

[0125] In some possible embodiments, such as Figure 7 As shown, the first snap-fit ​​structure 130 may include a first snap hook 1301, which is disposed on the bottom shell 110.

[0126] like Figure 8 As shown, the first snap-fit ​​structure 130 may also include a first snap-fit ​​groove 1302, which is disposed on the grille 120. When the grille 120 is installed on the bottom shell 110, the first snap-fit ​​hook 1301 engages with the first snap-fit ​​groove 1302.

[0127] In some possible embodiments, such as Figure 8 As shown, the first snap-fit ​​structure includes a second snap hook 1303, which is disposed on the grille 120.

[0128] like Figure 7 As shown, the first snap-fit ​​structure also includes a first snap-fit ​​boss 1304, which is disposed on the bottom shell 110. When the grille 120 is installed on the bottom shell 110, the second snap hook 1303 snaps onto the first snap-fit ​​boss 1304.

[0129] In some possible embodiments, such as Figure 7 As shown, the bottom shell 110 may include a bottom wall 1102, which is disposed toward the fresh air duct component 15.

[0130] like Figure 7As shown, the bottom shell 110 may also include a side wall 1103 connected to the bottom wall 1102 and extending along the thickness direction of the bottom wall 1102.

[0131] like Figure 8 As shown, the grille 120 may include a grille panel 1201, which is disposed toward the fresh air duct 15.

[0132] like Figure 8 As shown, the grille 120 may include a side plate 1202, which is connected to the grille panel 1201 and to the side wall 1103.

[0133] In some possible embodiments, such as Figure 7 As shown, the first hook 1301 is disposed on the side wall 1103.

[0134] like Figure 8 As shown, the first slot 1302 is disposed on the side plate 1202.

[0135] Thus, simply bring the side plate 1202 of the grille 120 close to the side wall 1103 of the bottom shell 110, align the first hook 1301 with the first slot 1302, and then push the grille 120 along the air outlet direction to complete the snap-fit. No additional complicated operations or tools are required, which improves installation efficiency. When the first hook 1301 and the first slot 1302 are engaged, the air pressure on the grille 120 during the air outlet process will be transmitted to the side wall 1103 through the side plate 1202, which effectively prevents the grille 120 from separating from the bottom shell 110 or becoming loose when subjected to airflow impact or other external forces (such as slight collisions or vibrations), thus ensuring the structural integrity of the grille assembly 100.

[0136] In some possible embodiments, such as Figure 8 As shown, the second hook 1303 is disposed on the side plate 1202.

[0137] like Figure 7 As shown, the first snap-fit ​​boss 1304 is disposed on the side wall 1103.

[0138] As the grille 120 moves toward the bottom shell 110 along the air outlet direction, the second hook 1303 gradually approaches the first engaging boss 1304. Since the second hook 1303 usually has a certain elasticity or deformability (depending on the material and structural design), when the second hook 1303 contacts the first engaging boss 1304, the hook will be slightly deformed by the pressure of the boss. As the grille 120 continues to move, after the second hook 1303 passes the edge of the first engaging boss 1304, it will engage above or around the first engaging boss 1304 due to its own elastic restoring force, thereby achieving the engagement between the two.

[0139] When the second hook 1303 engages with the first engagement boss 1304, the position of the grille 120 in the plane perpendicular to the air outlet direction is fixed. The first engagement boss 1304 provides support and positioning for the second hook 1303, preventing the grille 120 from shifting in the horizontal direction. At the same time, due to the engagement structure of the second hook 1303 and the first engagement boss 1304, the grille 120 is also stably fixed in the air outlet direction, avoiding the grille 120 from moving back and forth due to the pressure generated by the air flow.

[0140] In some possible embodiments, the first hook 1301 and the second hook 1303 are both elastic hooks. During the process of installing the grille 120 on the bottom shell 110, the first hook 1301 and the second hook 1303 are pressed against the side wall 1103. When the grille 120 is installed on the bottom shell 110, the first hook 1301 extends into the first slot 1302 and engages with the first slot 1302, and the second hook 1303 approaches the first engagement boss 1304 and engages with the first engagement boss 1304.

[0141] Since both the first hook 1301 and the second hook 1303 are elastic hooks, they can adaptively deform under pressure from the side wall 1103 during the installation of the grille 120 to the base shell 110. Even if there is a certain deviation in the initial alignment between the grille 120 and the base shell 110, the elastic hooks can adjust their position through deformation to adapt to the structure of the base shell 110 and successfully complete the engagement. During the pressure from the side wall 1103, the elastic deformation of the elastic hooks effectively buffers the impact force during installation, thereby reducing installation resistance. Compared with rigid hooks, elastic hooks do not generate excessive resistance due to hard collisions with the side wall 1103, making the installation process smoother. Workers do not need to use excessive force to overcome the friction and engagement force between the hooks and the base shell 110 when installing the grille 120; they only need to gently push the grille 120, and the elastic hooks will guide the grille 120 into the correct installation position while deforming. This not only reduces the difficulty of installation but also improves installation efficiency.

[0142] Furthermore, when the first hook 1301 extends into the first slot 1302 and engages with it, and the second hook 1303 approaches and engages with the first engagement boss 1304, the elastic restoring force of the elastic hook will cause the hook to form a tight connection with the slot or boss. This tight engagement can effectively prevent the grille 120 from loosening or falling off during use.

[0143] In some possible embodiments, such as Figure 4 As shown, the second snap-fit ​​structure 140 may include a second snap-fit ​​boss 1401, which is disposed on the inner wall of the mounting port 13a.

[0144] like Figure 8 As shown, the second snap-fit ​​structure 140 may also include a third snap hook 1402, which is disposed on the side plate 1202. When the grille 120 is installed on the panel 13, the third snap hook 1402 snaps onto the second snap-fit ​​boss 1401.

[0145] The second snap-fit ​​boss 1401 is on the inner wall of the mounting port 13a, and the third snap-fit ​​hook 1402 is on the side plate 1202 of the grille 120. When the two are snapped together, the grille 120 is fixed from multiple directions. In the vertical direction, the snap-fit ​​structure can bear the weight of the grille 120 itself and prevent it from sinking. In the horizontal direction, it restricts the translational movement of the grille 120, so that it will not easily move when subjected to external forces (such as vibration caused by air flow, accidental collision, etc.), thus ensuring the stability of the connection between the grille 120 and the panel 13, thereby ensuring the stability of the entire indoor unit 10 structure.

[0146] In some possible embodiments, the third hook 1402 is an elastic hook. During the process of installing the grille 120 into the mounting port 13a, the third hook 1402 is pressed against the inner wall of the mounting port 13a. When the grille 120 is installed into the mounting port 13a, the third hook 1402 approaches the second engaging boss 1401 and engages with the second engaging boss 1401.

[0147] When the grille 120 begins installation and approaches the mounting opening 13a, the third hook 1402 first contacts the inner wall of the mounting opening 13a. Since the third hook 1402 is an elastic hook, its material and structural design give it a certain elastic deformation capability. When it contacts the inner wall, the hook will be subjected to pressure from the inner wall. This pressure causes the hook to begin to elastically deform, and its shape will change accordingly according to the contact angle and force. When the grille 120 moves to a suitable position, so that the third hook 1402 approaches the second locking boss 1401, due to the elastic restoring force of the third hook 1402, the third hook 1402 will automatically return to its original shape. During this restoration process, the third hook 1402 will be tightly locked around the second locking boss 1401, completing the locking of the grille 120 and the mounting opening 13a, realizing automatic alignment and tight locking during the installation process.

[0148] Thus, after the elastic hook engages with the second engagement boss 1401, its elastic restoring force can ensure that the third hook 1402 and the second engagement boss 1401 form a tight connection, making the grille 120 more securely fixed at the mounting opening 13a, and effectively resisting various external forces that may be encountered during use, such as pressure generated by air flow, vibration and accidental collisions.

[0149] In some possible embodiments, such as Figure 9As shown, a detection port 1102a is provided on the bottom wall 1102, and the detection port 1102a is connected to the ventilation cavity.

[0150] The indoor unit 10 may include an air quality detection module 16, which is disposed on the side of the bottom wall 1102 away from the grille panel 1201 and located at the detection port 1102a. The air quality detection module 16 is used to detect air quality.

[0151] Fresh air first enters the ventilation cavity formed by the bottom shell 110 and the grille 120 after passing through the ventilation port 1101 of the bottom shell 110 from the fresh air duct 15. Inside the ventilation cavity, some air flows to the location of the air quality detection module 16 through the detection port 1102a on the bottom wall 1102. Since the detection port 1102a is connected to the ventilation cavity, the air in the ventilation cavity can naturally diffuse to the detection port 1102a, providing a detection sample for the air quality detection module 16. The air quality detection module 16 detects various air quality indicators of the passing air, such as the concentration of particulate matter, the content of harmful gases (such as formaldehyde, benzene and other volatile organic compounds), carbon dioxide concentration, humidity and temperature.

[0152] In this way, by placing the air quality detection module 16 at the detection port 1102a on the bottom wall 1102, the fresh air that is about to be blown into the indoor space is directly detected, ensuring that the detected air sample is the air that the user actually breathes, so that the detection results can accurately reflect the real-time changes in indoor air quality.

[0153] The space detection module may include a TVOC sensor (TVOC is an abbreviation for "Total Volatile Organic Compounds").

[0154] In some possible embodiments, such as Figure 9 As shown, the grille assembly 100 may include a wind deflector 160, which is disposed on the bottom wall 1102 and encloses the ventilation opening 1101.

[0155] The wind deflector 160 surrounds the vent 1101 and can effectively guide the airflow direction of the fresh air entering the ventilation cavity from the fresh air duct 15. When fresh air enters the vent 1101 from the duct, without the wind deflector 160, the air may diffuse in all directions, causing some air to form vortices or flow randomly in the ventilation cavity. The wind deflector 160 can guide the air in a specific direction, so that it enters the ventilation cavity along a more orderly path, thereby optimizing the initial airflow direction and improving the efficiency of air circulation.

[0156] In some possible embodiments, such as Figure 10 and Figure 11As shown, a wiring port 12a can be provided on the flange 12. Along the air outlet direction, the wiring port 12a corresponds to the mounting port 13a and the grille assembly 100.

[0157] A display module can be installed on the panel 13, and the display module is electrically connected to the control module in the host 11 through the wiring port 12a.

[0158] The wiring port 12a on the flange 12 provides a dedicated channel for wiring between the display module and the control module inside the host 11. Compared with the situation where the wires may need to bypass multiple components or pass through narrow spaces when there is no wiring port 12a, the wiring process is simplified and the assembly efficiency is improved. When the indoor unit 10 needs maintenance or repair, such as checking whether there is a problem with the wiring connection between the display module and the control module, the presence of the wiring port 12a allows technicians to quickly locate and find the wiring. Through the wiring port 12a, the wiring connection can be directly observed, which is convenient for wiring inspection, testing and repair. The design of the grille assembly 100 corresponding to the wiring port 12a and the mounting port 13a allows the grille assembly 100 to effectively cover the wiring port 12a and the wires inside it. When viewed from the front or side of the indoor unit 10, the user cannot see the messy wires, making the appearance of the entire device cleaner and more beautiful.

[0159] In some possible embodiments, such as Figure 10 and Figure 11 As shown, a limiting component 12b is provided at the wiring port 12a. The limiting component 12b is used to limit the position of the wire connecting the display module and the control module in the host 11 at the wiring port 12a.

[0160] The limiting component 12b provides precise positioning for the wires at the wiring port 12a. When the wires connecting the display module and the control module pass through the wiring port 12a, the limiting component 12b can limit the position of each wire, so that they are arranged according to the predetermined path. This can prevent the wires from piling up messily near the wiring port 12a, reduce unnecessary space occupation, achieve a more reasonable layout in a limited space, and improve the aesthetics of the entire device.

[0161] Furthermore, during the operation of the indoor unit 10, the wires may sway due to factors such as fan operation, air flow, or slight vibration of the equipment. The presence of the limiting component 12b can effectively prevent the wires from swaying and shifting at the wiring port 12a.

[0162] In some possible implementations, the indoor unit 10 is fixedly mounted on the ceiling.

[0163] like Figure 12As shown, the indoor unit 10 may also include two sets of decorative components 17. The two sets of decorative components 17 are respectively connected to both ends of the indoor unit 10 along its length, so that the indoor unit 10 and the two sets of decorative components 17 form a beam-like structure. This beam-like structure should be understood as echoing the lines of the wall or ceiling along its length. This beam-like structure breaks away from the conventional appearance of the indoor unit 10; it is no longer a monotonous square shape hung on the wall or placed in a corner, but rather integrated with the interior ceiling, thus becoming part of the interior decoration and enhancing the aesthetics of the interior space.

[0164] like Figure 3 As shown, each decorative component 17 includes a front panel 17a, which is located on the same side as the panel 13. The front panel 17a and the panel 13 are located on the same side, which has a certain sense of design and decoration, and can match the overall decoration style of the room, enhance the appearance of the indoor unit 10, and make the indoor environment more harmonious and beautiful.

[0165] like Figure 3 As shown, the fresh air duct component 15 is located outside the main unit 11 and within the space formed by the front panel 17a, the rear panel 17b, and the bottom panel 17c.

[0166] The fresh air duct component 15 is located outside the main unit 11 and within the space enclosed by the decorative component 17, making it easier for maintenance personnel to access the duct. When regular maintenance of the fresh air duct component 15 is required, such as cleaning the inside of the duct, checking whether the duct connection is tight, or replacing aging duct components, there is no need to disassemble the complex indoor unit 10 main unit 11. Simply open the base plate 17c of the decorative component 17 to directly access the fresh air duct component 15, reducing the difficulty and time cost of maintenance and improving the efficiency of maintenance work.

[0167] Furthermore, the layout of the fresh air duct component 15 outside the main unit 11 can avoid conflicts with the layout of other components inside the indoor unit 10 (such as fans, heat exchangers, etc.). Inside the main unit 11, due to limited space, the distance between various components is relatively close. If the fresh air duct component 15 is also inside, it may cause the airflow path to be tortuous and increase the airflow resistance. However, the duct outside the main unit 11 can be designed and laid out more reasonably according to the principles of aerodynamics, so that the fresh air flows more smoothly in the duct and reduces wind resistance. This not only helps to improve ventilation efficiency, but also reduces the energy consumption of the fan.

[0168] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the air conditioner of this application, and are not intended to limit it; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
