Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] The following is combined Figures 1-12 This invention describes the indoor unit of an air conditioner.

[0052] An embodiment of the first aspect of this utility model provides an indoor unit for an air conditioner, such as... Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes a housing 100 and an air intake assembly 300.

[0053] The housing 100 has an indoor air inlet 140 at the front. The air intake assembly 300 includes a grille drive component 310 and an air intake grille 320. The grille drive component 310 is disposed on the housing 100, and the air intake grille 320 is disposed on the indoor air inlet 140. The air intake grille 320 is connected to the grille drive component 310. The grille drive component 310 is used to drive the air intake grille 320 to open or close the indoor air inlet 140.

[0054] It should be noted that the housing 100 may have a top and a bottom, and the distance from the top to the bottom of the housing 100 represents the height of the housing 100. The housing 100 also has a length direction, with the distance from one end of the housing 100 to the other end representing the length of the main body 150. The housing 100 may have a front and a rear side arranged opposite to each other. The side of the housing 100 facing the user is the front side of the housing 100, and the distance from the front side to the rear side represents the front-rear direction of the housing 100. The height, length, and front-rear directions of the housing 100 are perpendicular.

[0055] In this embodiment, the indoor unit of the air conditioner can be installed vertically, and the height direction of the indoor unit is parallel to the vertical direction.

[0056] It is understandable that an indoor air inlet 140 is formed on the casing 100. The indoor air inlet 140 is located on the front side of the casing 100 and serves as the entrance for air to enter the casing 100, enabling the indoor unit of the air conditioner to adopt a front-flow airflow method. The top of the indoor unit of the air conditioner can be installed against the wall or the indoor ceiling, achieving a top-mounted installation. Air can enter the interior of the casing 100 through the indoor air inlet 140 on the front side of the casing 100. Therefore, when the indoor unit of the air conditioner is installed top-mounted, it will not obstruct the indoor air inlet 140, ensuring smooth airflow and thus ensuring that the cooling and heating effects of the air conditioner are not affected.

[0057] Furthermore, an air intake assembly 300 is provided in the indoor air intake 140. The air intake assembly 300 includes a grille drive component 310 and an air intake grille 320. The air intake grille 320 is provided in the indoor air intake 140. The grille drive component 310 is provided in the housing 100 and connected to the air intake grille 320. The grille drive component 310 is used to drive the air intake grille 320 to open or close the indoor air intake 140.

[0058] Understandably, when the indoor unit of the air conditioner is turned on, the grille drive component 310 drives the air intake grille 320 to open the indoor air intake 140 to achieve cooling or heating of the indoor environment; when the indoor unit of the air conditioner is turned off, the grille drive component 310 drives the air intake grille 320 to close the indoor air intake 140, improving the overall aesthetics of the indoor unit when not in use and reducing the problem of dust accumulation.

[0059] The air conditioner indoor unit provided in this embodiment of the utility model has an indoor air inlet 140 at the front of the casing 100 to adopt a front air intake method. Therefore, when installed close to the ceiling, the indoor air inlet 140 will not be blocked, ensuring smooth air intake and thus ensuring that the air conditioning cooling and heating effect is not affected. In addition, the indoor air inlet 140 is provided with a closable air intake grille 320. In the off state, the air intake grille 320 is driven by the grille drive component 310 to close the indoor air inlet 140, improving the overall aesthetics of the air conditioner indoor unit when not in use and reducing dust accumulation on the air conditioner.

[0060] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the grille drive component 310 includes a drive member 311 and a connecting rod 312. The drive member 311 is disposed in the housing 100. The connecting rod 312 is connected to the output of the drive member 311. The air intake grille 320 is movably connected to the connecting rod 312. The drive member 311 drives the connecting rod 312 to move, thereby causing the air intake grille 320 to rotate, thereby opening or closing the indoor air intake 140.

[0061] Optionally, multiple air intake grilles 320 are arranged sequentially along the height direction of the housing 100. Each air intake grille 320 is arranged parallel to the length direction of the housing 100. The air intake grille 320 is located at the indoor air inlet 140. Both ends of the air intake grille 320 along the length direction have rotating parts that are rotatably connected to the housing 100. The drive unit 311 is disposed on the inner wall of the housing 100 and located above the indoor air inlet 140. The connecting rod 312 is arranged vertically. The upper end of the connecting rod 312 is connected to the output of the drive unit 311 through the swing arm 313. Multiple air intake grilles 320 are arranged at intervals along the length direction of the connecting rod 312, and the air intake grilles 320 are movably connected to the connecting rod 312.

[0062] In this embodiment, the driving component 311 is a drive motor, and the air intake grille 320 has a hinge portion that is hinged to the connecting rod 312.

[0063] It is understandable that the swing arm 313 is driven by the drive motor to swing, thereby driving the connecting rod 312 to move. The connecting rod 312 is connected to multiple air intake grilles 320. When the connecting rod 312 moves, it drives each grille to rotate around its own rotation center, thereby realizing the opening and closing of the air intake grille 320.

[0064] It should be noted that when the air intake grilles 320 are closed, all air intake grilles 320 cover the indoor air intake 140 to close the indoor air intake 140.

[0065] Furthermore, multiple air intake grilles 320 are arranged at equal intervals along the height direction of the housing 100.

[0066] In one embodiment of this utility model, such as Figure 3 As shown, the housing 100 includes a main body 150 and a front panel 160. The front part of the main body 150 has a mounting port 151. The front panel 160 is disposed at the mounting port 151, and the first end of the front panel 160 is rotatably connected to the first side of the mounting port 151. The indoor air inlet 140 is disposed on the front panel 160.

[0067] It is understood that the housing 100 includes a main body 150 and a front panel 160 rotatably connected to the main body 150. The indoor air inlet 140 and the air intake assembly 300 are arranged on the front panel 160, so that the air intake assembly 300 can be maintained and repaired by rotating the front panel 160.

[0068] Optionally, a filter 400 may be provided on the side of the front panel 160 near the interior of the main body 150.

[0069] Understandably, the filter 400 is arranged inside the front panel 160 to filter the air entering the main body 150, reduce the impact of large particulate pollutants on the internal components of the main body 150, and help optimize the airflow path to improve overall performance and efficiency.

[0070] It should be noted that the filter element 400 is located on the front panel 160, which makes it easy to rotate and open the front panel 160 for periodic inspection of the filter element 400.

[0071] Furthermore, the filter element 400 is detachably mounted on the front panel 160, facilitating its removal for cleaning or replacement.

[0072] In this embodiment, the housing 100 includes a main body 150 and a front panel 160. The front panel 160 is rotatably connected to the main body 150 to open or close the mounting port 151 on the main body 150. The air intake assembly 300 and the filter element 400 are both disposed on the front panel 160. The filter element 400 is a filter screen. When the filter screen is clogged, the front panel 160 can be rotated open and the filter screen can be pulled out for cleaning.

[0073] In one embodiment of this utility model, such as Figure 3 As shown, a first snap-fit ​​portion 161 is provided at the second end of the front panel 160, and a second snap-fit ​​portion 152 that cooperates with the first snap-fit ​​portion 161 is provided on the second side of the mounting port 151.

[0074] It is understood that the front panel 160 is provided with a mounting opening 151 at the front of the main body 150, and the first end of the front panel 160 is rotatably connected to the first side of the mounting opening 151 to open or close the mounting opening 151; and a first snap-fit ​​part 161 is provided at the second end of the front panel 160, and a second snap-fit ​​part 152 is provided on the second side of the mounting opening 151 to cooperate with the first snap-fit ​​part 161. When the front panel 160 closes the mounting opening 151, the first snap-fit ​​part 161 undergoes elastic deformation and enters the corresponding position of the second snap-fit ​​part 152. When the first snap-fit ​​part 161 is fully inserted, it elastically returns to its original shape, and the two form a firm snap-fit ​​connection.

[0075] It should be noted that an appropriate external force (such as pressing or pulling) can be applied to cause the first latching part 161 to undergo elastic deformation again, so as to disengage the first latching part 161 from the second latching part 152 and rotate the front panel 160.

[0076] Furthermore, a seal is provided between the main body 150 and the front panel 160 to improve the sealing between the main body 150 and the front panel 160.

[0077] Understandably, the seal fills the gap between the front panel 160 and the body 150 to prevent external contaminants (such as dust, particulate matter) or gases (such as air, moisture) from entering the interior of the body 150.

[0078] In one embodiment of this utility model, such as Figure 1 As shown, the indoor unit of the air conditioner also includes a cross-flow fan 500, an evaporator 600, and a frame 700 disposed inside the casing 100; the bottom of the casing 100 has an air outlet, the evaporator 600 is close to the indoor air inlet 140, the cross-flow fan 500 is close to the air outlet, and the frame 700 is a frame structure used to support the cross-flow fan 500, the evaporator 600 and other internal components, and to ensure their stability during operation.

[0079] Understandably, air enters the casing 100 through the indoor air inlet 140. In cooling mode, the refrigerant in the evaporator 600 absorbs heat, cooling the air passing through it. In heating mode, the evaporator 600 acts as a condenser, releasing heat to the passing air. The air exiting the evaporator 600 is then driven by the cross-flow fan 500. The purpose of the cross-flow fan 500 is to effectively and quickly, evenly, blow the heat-exchanged air through the outlet into the indoor environment.

[0080] The air conditioner indoor unit provided in this embodiment adopts a front-facing and bottom-facing air intake and exhaust method. An air intake grille 320 is set on the front panel 160, which can ensure smooth air intake even when installed close to the ceiling. The air conditioner indoor unit only needs to be 5mm away from the ceiling to meet the user's needs for ceiling installation. The air intake grille 320 is an openable grille. When the air conditioner is turned off, the air intake grille 320 closes, avoiding the problems of poor appearance and easy dust accumulation of fixed grilles.

[0081] In one embodiment of this utility model, such as Figures 7 to 9 As shown, the indoor unit of the air conditioner also includes an air guide assembly 200 disposed on the casing 100.

[0082] The housing 100 has an air outlet, which includes a bottom air outlet 110 and a side air outlet 120. The air guide assembly 200 includes a first air guide plate 210 and a second air guide plate 220. The first air guide plate 210 is disposed at the bottom air outlet 110 and is adapted to open or close the bottom air outlet. The second air guide plate 220 is disposed at the side air outlet 120 and is adapted to open or close the side air outlet.

[0083] The air guide assembly 200 has a first state and a second state. In the first state, the first air guide plate 210 closes the bottom air outlet 110 and the second air guide plate 220 opens the side air outlet 120. In the second state, the first air guide plate 210 opens the bottom air outlet 110 and the second air guide plate 220 closes the side air outlet 120.

[0084] Understandably, the first air guide plate 210 is located at the bottom air outlet 110. When the first air guide plate 210 opens the bottom air outlet 110, the airflow inside the casing 100 enters the indoor environment from the bottom air outlet 110. The second air guide plate 220 is located at the side air outlet 120. When the second air guide plate 220 opens the side air outlet 120, the airflow inside the casing 100 enters the indoor environment from the side. Figure 9 As shown, in heating mode, the first air guide plate 210 opens the bottom air outlet 110 and the second air guide plate 220 closes the side air outlet 120, selecting the bottom air outlet 110 as the air supply mode, thus achieving downward air supply; as Figure 8 As shown, in cooling mode, the first air guide plate 210 closes the bottom air outlet 110 and the second air guide plate 220 opens the side air outlet 120, and the side air outlet 120 is selected to deliver air, that is, to achieve a flat air delivery mode, so as to avoid direct air blowing and causing user discomfort.

[0085] The air conditioner indoor unit provided in this embodiment of the utility model has a bottom air outlet 110 and a side air outlet 120 arranged on the casing 100. A first air guide plate 210 is provided at the bottom air outlet 110 and a second air guide plate 220 is provided at the side air outlet 120. In the cooling mode, the air guide assembly 200 is in a first state, in which the first air guide plate 210 closes the bottom air outlet 110 and the second air guide plate 220 opens the side air outlet 120 to achieve a horizontal air supply mode. In the heating mode, the air guide assembly 200 is in a second state, in which the first air guide plate 210 opens the bottom air outlet 110 and the second air guide plate 220 closes the side air outlet 120 to achieve a downward air supply mode. Thus, the air guide assembly 200 can switch between the first state and the second state to achieve two air supply modes, thereby improving the user experience.

[0086] In one embodiment of this utility model, such as Figures 7 to 9 As shown, the first air guide plate 210 is rotatably connected to the side of the bottom air outlet 110 near the side air outlet 120, and the first air guide plate 210 is adapted to open or close the bottom air outlet 110.

[0087] Optionally, the first air guide plate 210 is arranged at the bottom air outlet 110, and the side of the first air guide plate 210 near the side air outlet 120 is rotatably connected to the housing 100. The first driving component is used to drive the first air guide plate 210 to rotate between a first bottom position and a second bottom position. When the first air guide plate 210 is in the first bottom position, the first air guide plate 210 closes the bottom air outlet 110. When the first air guide plate 210 is in the second bottom position, the first air guide plate 210 opens the bottom air outlet 110.

[0088] For example, the first drive component includes a first drive member disposed on the housing 100 and a first rotating shaft disposed at the output of the first drive member, the first rotating shaft being connected to the first air guide plate 210.

[0089] Furthermore, the second air guide plate 220 is rotatably connected to the side of the side air outlet 120 away from the bottom air outlet 110, and the second air guide plate 220 is adapted to open or close the side air outlet 120.

[0090] Optionally, the second air guide plate 220 is arranged at the side air outlet 120. The side of the second air guide plate 220 away from the bottom air outlet 110 is rotatably connected to the housing 100. The second driving component is used to drive the second air guide plate 220 to rotate between the first side position and the second side position. When the second air guide plate 220 is in the first side position, the second air guide plate 220 closes the side air outlet 120. When the second air guide plate 220 is in the second side position, the second air guide plate 220 opens the side air outlet 120.

[0091] It should be noted that the second drive component can adopt the same structure as the first drive component. The second drive component includes a second drive member and a second rotating shaft disposed at the output of the second drive member. The second rotating shaft is connected to the second air guide plate 220.

[0092] It is understandable that, according to the air supply requirements, the first air guide plate 210 can be driven to rotate by the first driving component, and the second air guide plate 220 can be driven to rotate by the second driving component, so as to realize the switching of the air guide assembly 200 between the first state and the second state.

[0093] In one embodiment of this utility model, such as Figure 10 As shown, the air guide assembly 200 also has a third state; in the third state, the first air guide plate 210 opens the bottom air outlet 110 and the second air guide plate 220 opens the side air outlet 120.

[0094] Understandably, when the air guide assembly 200 is in the third state, the first air guide plate 210 opens the bottom air outlet 110 and the second air guide plate 220 opens the side air outlet 120. The airflow inside the casing 100 enters the indoor environment from the bottom air outlet 110 and the side air outlet 120 at the same time, thereby sending air into the indoor environment through two different air outlet directions to promote indoor air circulation, make the indoor temperature distribution more uniform, and thus improve the user experience.

[0095] Optionally, in the third state, the air guide assembly 200 has the first air guide plate 210 arranged along the direction of the airflow and the second air guide plate 220 located outside the side air outlet 120. At this time, the air guide assembly 200 is in the maximum air supply position, which can deliver cold or hot air at the maximum wind speed, quickly adjust the indoor temperature, and shorten the time to reach the set temperature.

[0096] Furthermore, in the third state, the air guide assembly 200 rotates the first air guide plate 210 to the uppermost position and is completely located outside the side air outlet 120, so as to avoid intruding into the air supply airflow area and affecting the air volume and generating abnormal noise.

[0097] Furthermore, to reduce the impact of the first air guide plate 210 on the air volume, the first air guide plate 210 is rotated outside the casing 100 and arranged along the direction of the airflow. It should be noted that having the first air guide plate 210 located outside the casing 100 reduces air volume loss compared to having it located inside the casing 100, and can effectively increase the maximum air volume at the same rotation speed.

[0098] In one embodiment of this utility model, such as Figure 7 As shown, the air guide assembly 200 also has a fourth state, in which the first air guide plate 210 closes the bottom air outlet 110 and the second air guide plate 220 closes the side air outlet 120.

[0099] In one specific embodiment of this utility model, such as Figures 7 to 10 As shown, the air guide assembly 200 includes a first air guide plate 210 disposed at the bottom air outlet 110 and a second air guide plate 220 disposed at the side air outlet 120. The side of the first air guide plate 210 near the side air outlet 120 is rotatably connected to the housing 100, and the side of the second air guide plate 220 away from the bottom air outlet 110 is rotatably connected to the housing 100. The first air guide plate 210 and the second air guide plate 220 can rotate independently about their respective rotation centers. The air guide assembly 200 has a first state, a second state, a third state, and a fourth state.

[0100] like Figure 7 As shown, in the initial state, the air guide assembly 200 is in the fourth state, the first air guide plate 210 closes the bottom air outlet 110 and the second air guide plate 220 closes the side air outlet 120. At this time, the first air guide plate 210 is arranged horizontally and the second air guide plate 220 is arranged vertically.

[0101] like Figure 10 As shown, in the maximum air supply mode, the air guide assembly 200 is in the third state. When the air guide assembly 200 switches from the fourth state to the third state, the second air guide plate 220 is rotated clockwise to the uppermost position, completely outside the side air outlet 120, to avoid intruding into the air supply airflow area, and the first air guide plate 210 is rotated clockwise to be arranged along the air supply airflow direction.

[0102] like Figure 8 As shown, in cooling mode, the air guide assembly 200 is in the first state. When the air guide assembly 200 switches from the fourth state to the first state, the second air guide plate 220 is rotated clockwise to the uppermost position, completely outside the side air outlet 120, to avoid intruding into the air supply airflow area. The first air guide plate 210 is in the closed position and does not move. The cooling upward main airflow flows upward along the inner surface of the second air guide plate 220 to avoid direct blowing and causing user discomfort.

[0103] like Figure 9 As shown, in heating mode, the air guide assembly 200 is in the second state. When the air guide assembly 200 switches from the fourth state to the second state, the second air guide plate 220 is rotated clockwise by a specific angle, and the first air guide plate 210 is rotated to a nearly vertical position to maximize the vertical downward airflow. It should be noted that the specific angle of rotation of the second air guide plate 220 is to provide clearance for the rotation of the first air guide plate 210, and when the first air guide plate 210 is in the vertical position, the second air guide plate 220 and the first air guide plate 210 are either close together or the distance between them is minimized.

[0104] The indoor unit of the air conditioner provided in this embodiment can be rotated to different positions by the first air guide plate 210 and the second air guide plate 220, so as to realize the diversity of the airflow direction and switch the air guide assembly 200 between the first state, the second state and the third state. It can realize three air supply modes: cooling upward blowing, heating downward blowing and maximum air supply, so as to provide users with better physical comfort.

[0105] It should be noted that traditional single air guide vane designs create a concentrated, high-speed "wind wall effect" in the air conditioner's output, especially in cooling mode, causing strong discomfort to users. To reduce the discomfort caused by direct cold air blowing, micro-perforations could be added to the air guide vane. However, this design reduces the airflow and affects the performance of the indoor unit. This embodiment, however, does not affect the airflow and therefore the performance of the indoor unit. Thus, this embodiment uses a dual air guide vane structure, which solves the problem of direct cold air blowing while maintaining the original airflow.

[0106] In one specific embodiment of this utility model, such as Figure 8 and Figure 12 As shown, when the first air guide plate 210 closes the bottom air outlet 110, the upper surface of the first air guide plate 210 near the side air outlet 120 is an arc surface, and the height of the arc surface gradually decreases from the end near the side air outlet 120 to the end away from the side air outlet 120.

[0107] Optionally, the tangent of the arc surface near the side air outlet 120 has a preset angle α with the plane where the first air guide plate 210 is located, the preset angle α being greater than or equal to 15° and less than or equal to 30°.

[0108] It is understandable that the upper plane of the first air guide plate 210 near the side air outlet 120 is a conical arc profile, and the angle α between the tangent of the arc profile and the horizontal line satisfies 30°>α>15°.

[0109] Furthermore, the top of the arc surface and the lower plane of the first air guide plate 210 have a preset height H, which is greater than or equal to 8mm and less than or equal to 15mm.

[0110] It is understandable that the height H at the top of the arc satisfies 15mm > H > 8mm. By guiding the airflow upward through the conical arc, the effect of cool air not blowing on people is achieved. At the same time, by reasonably setting the size of H, excessive air volume loss is avoided.

[0111] In one embodiment of this utility model, such as Figure 7 and Figure 11As shown, the housing 100 has a first positioning part 130 and the first air guide plate 210 has a second positioning part 211. When the first air guide plate 210 closes the bottom air outlet 110, the second positioning part 211 overlaps with the first positioning part 130.

[0112] It is understandable that a first positioning part 130 is provided on the side of the bottom air outlet 110 away from the side air outlet 120, and a second positioning part 211 is provided on the edge of the first air guide plate 210. When the first air guide plate 210 is rotated to the closed position to completely cover the bottom air outlet 110, the second positioning part 211 forms an overlapping fit with the first positioning part 130 through elastic deformation or guide slope.

[0113] Optionally, the second positioning part 211 is a positioning groove, and the first positioning part 130 is a positioning protrusion. The positioning protrusion is embedded in the positioning groove to achieve the positioning of the first air guide plate 210 when the bottom air outlet 110 is closed. In other embodiments, the first positioning part 130 and the second positioning part 211 may also adopt a matching hook and groove structure, or a matching protrusion and latch structure.

[0114] In this embodiment, the overlap length L between the positioning groove and the positioning protrusion should be greater than or equal to 5mm. It should be noted that the overlap length refers to the length of the contact surface between the positioning groove and the positioning protrusion.

[0115] It is understandable that the positioning groove and positioning protrusion can ensure the sealing between the first air guide plate 210 and the housing 100 during positioning, so that there will be no air leakage between the first air guide plate 210 and the housing 100 during cooling, thereby avoiding the problem of cold air blowing in and condensation on the housing 100.

[0116] It should be noted that when the first air guide plate 210 is rotated to the closed position, the outer surface of the first air guide plate 210 and the outer wall of the housing 100 are made to form a continuous and flat transition surface through the cooperation of the positioning groove and the positioning protrusion. This not only achieves the sealing of the bottom air outlet 110, but also ensures the overall aesthetics of the product in the closed state, achieving a seamless visual effect.

[0117] A second aspect of this utility model provides an air conditioner that includes the indoor unit provided in any of the above embodiments.

[0118] Optionally, the air conditioner includes an indoor unit and an outdoor unit, with the indoor unit located indoors and the outdoor unit located outdoors; the air conditioner also includes a compressor and a throttling device. The indoor unit, compressor, outdoor unit, and throttling device are connected through refrigerant piping to form a refrigeration system.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 of the technical features.
