Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to an indoor air conditioning unit, an air conditioner, and a control method. Background Technology

[0002] Currently, most wall-mounted air conditioners on the market adopt a rectangular box structure. Their internal air duct design mainly uses conventional axial or cross-flow fans in conjunction with flat air guide plates. The air inlet is usually located at the bottom or front of the unit, while the air outlet is located at the top or front of the unit. The air direction is adjusted by mechanically swinging air guide blades.

[0003] However, the existing flat-plate air guide design limits the air outlet angle, easily leading to direct airflow, which reduces human comfort and causes uneven indoor temperature distribution, resulting in localized overheating or undercooling. Summary of the Invention

[0004] The main objective of this invention is to provide an indoor air conditioning unit, an air conditioner, and a control method to solve the problem in the prior art where the use of a flat air guide plate restricts the air outlet angle, easily causing direct airflow and thus reducing human comfort.

[0005] To achieve the above objectives, according to one aspect of the present invention, an air conditioning indoor unit is provided, including a first air guide housing having an arc-shaped first air guiding surface;

[0006] The main unit has an air inlet, and a first air guide shell is movably disposed on one side of the main unit so that when the first air guide shell moves away from the main unit, a first air outlet zone is formed between the first air guide shell and the main unit.

[0007] The fan blade unit is installed inside the main unit to guide the airflow from the air inlet to the first guide surface for guidance, so that the guided airflow flows out from the first air outlet area.

[0008] Furthermore, a sliding structure is provided on the first air guide housing, the sliding structure including a sliding element, and the main unit includes:

[0009] The main support structure is equipped with an air inlet.

[0010] The mating structure is installed on the supporting body, and the mating structure includes mating parts;

[0011] The sliding component and the mating component slide together to allow the first air guide shell to move relative to the supporting body.

[0012] Furthermore, the sliding structure also includes a push mounting position, and the mating structure also includes a pusher. The pusher is telescopically disposed on one side of the mating member along the movement direction of the first air guide housing. The pusher end of the pusher is disposed in the push mounting position so that the first air guide housing slides relative to the supporting body when the pusher extends or retracts.

[0013] Furthermore, the sliding structure also includes a push mounting position, and the mating structure also includes a push member. The mating member is provided with a push mounting portion extending along the movement direction of the first air guide housing. At least a portion of the push member is located inside the push mounting portion, and the push end of the push member is located outside the push mounting portion and connected to the push mounting position.

[0014] Furthermore, the mating structure also includes a clamping member disposed on the push mounting portion. The clamping member has a through hole, and at least a portion of the push member passes through the through hole and the push mounting portion to connect the push end of the push member with the push mounting position.

[0015] Furthermore, the mating structure also includes a limiting component, which is disposed within the push mounting portion and located at the end of the push mounting portion away from the pressing component. The limiting component has a limiting surface that cooperates with the push member to limit the circumferential displacement of the push member relative to the first air guide housing.

[0016] Furthermore, the indoor unit of the air conditioner also includes an evaporator, which is installed inside the supporting body;

[0017] The drainage structure is installed on the supporting body and located below the air inlet. The drainage structure has a receiving surface, which is opposite to the water outlet of the evaporator, so as to receive the condensate generated by the evaporator and guide it to the outside of the main unit.

[0018] Furthermore, the indoor unit of the air conditioner also includes a second air guide housing; the second air guide housing has an arc-shaped second air guide surface, and the second air guide housing is movably arranged so that when the second air guide housing moves toward the side away from the main unit, a second air outlet area is formed between the second air guide housing and the main unit;

[0019] The fan blade unit is also used to guide the airflow from the air inlet to the second guide surface so that the guided airflow flows out from the second air outlet area.

[0020] Furthermore, the indoor unit of the air conditioner also includes a protective component, which is installed on the main unit and located between the fan blade unit and the second air guide shell. The protective component is provided with an overflow channel so that the airflow at the air inlet can enter the second air guide surface through the overflow channel.

[0021] Furthermore, the fan blade unit includes a drive element disposed on the side of the protective component of the indoor unit of the air conditioner away from the second air guide housing, and the drive element has a drive end;

[0022] An axial fan blade is mounted on the drive end to introduce airflow from the air inlet to the first guide surface and / or the second guide surface via a drive element.

[0023] Furthermore, the air conditioner indoor unit also includes mounting components, which are detachably mounted on the main unit to mount the air conditioner indoor unit on the mounting base.

[0024] According to another aspect of the present invention, an air conditioner is provided, comprising an indoor unit and an outdoor unit, wherein the indoor unit is the aforementioned indoor unit.

[0025] According to another aspect of the present invention, a control method for an air conditioner indoor unit is provided, the control method being applicable to the aforementioned air conditioner indoor unit, the control method comprising:

[0026] In response to user operation requests, generate corresponding operation instructions;

[0027] According to the operation instructions, when the operating mode of the indoor unit of the air conditioner is determined to be either cooling mode or heating mode, the first air guide shell of the indoor unit of the air conditioner is controlled to move away from the main unit of the indoor unit of the air conditioner to form the first air outlet zone.

[0028] The control fan blade unit introduces the airflow from the air inlet of the main unit to the first guide surface of the first air guide shell for guidance, so that the guided airflow flows out from the first air outlet area.

[0029] Furthermore, after the step of directing the airflow to exit from the first outlet zone, the control method further includes:

[0030] Obtain the user's real-time body temperature;

[0031] When the real-time perceived temperature exceeds the preset temperature range, the first air guide housing is controlled to move towards the supporting body of the main unit; and / or,

[0032] When the real-time perceived temperature is within the preset temperature range, the first air guide shell is controlled to maintain its current position.

[0033] Furthermore, the control method also includes controlling the second air guide shell of the air conditioner indoor unit to move away from the main unit when the operating mode of the indoor unit is determined to be either cooling mode or heating mode according to the operation command, so as to form a second air outlet zone.

[0034] The control fan blade unit introduces the airflow from the air inlet of the main unit to the second guide surface of the second air guide shell for guidance, so that the guided airflow flows out from the second air outlet area.

[0035] Furthermore, after the step of guiding the airflow to exit from the second outlet zone, the control method further includes:

[0036] Obtain the user's real-time body temperature;

[0037] When the real-time perceived temperature is lower than the preset temperature range, the second air guide housing is controlled to move towards the supporting body of the main unit; and / or,

[0038] When the real-time perceived temperature is within the preset temperature range, the second air guide shell is controlled to maintain its current position.

[0039] When the indoor unit of the air conditioner is working, the fan blade unit starts up, drawing indoor air in through the air inlet on the main unit and transporting it axially to the arc-shaped first guide surface of the first guide shell. Under the guidance of the curved surface of the first guide surface, the airflow smoothly changes direction, and the flow direction gradually transitions from axial to tangential to the direction along the guide surface. Then, it flows out through the annular first air outlet area formed between the first guide shell and the main unit due to the movement of the first guide shell away from the main unit. The airflow continues to diffuse because it adheres to the outer contour of the first guide surface, forming a low-speed, wide-angle airflow field without a direct blowing sensation.

[0066] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0067] Currently, most wall-mounted air conditioners on the market adopt a rectangular box structure. Their internal air duct design mainly uses conventional axial or cross-flow fans in conjunction with flat air guide plates. The air inlet is usually located at the bottom or front of the unit, while the air outlet is located at the top or front of the unit. The air direction is adjusted by mechanically swinging air guide blades.

[0068] However, the existing flat-plate air guide design limits the air outlet angle, easily leading to direct airflow, which reduces human comfort and causes uneven indoor temperature distribution, resulting in localized overheating or undercooling. The main objective of this invention is to provide an indoor air conditioning unit, air conditioner, and control method to solve the problem of limited air outlet angle and direct airflow caused by the use of a flat-plate air guide in the prior art, thus reducing human comfort.

[0069] like Figures 1 to 15 As shown, this application embodiment provides an air conditioner indoor unit to address the above problems, including a first air guide housing 100, the first air guide housing 100 having an arc-shaped first air guide surface 101;

[0070] The main unit 200 is provided with an air inlet 300. The first air guide housing 100 is movably disposed on one side of the main unit 200 so that when the first air guide housing 100 moves away from the main unit 200, a first air outlet area 400 is formed between the first air guide housing 100 and the main unit 200.

[0071] The fan blade unit 500 is installed inside the main body unit 200 to guide the airflow from the air inlet 300 to the first guide surface 101 for guidance, so that the guided airflow flows out from the first air outlet area 400.

[0072] like Figures 1 to 15As shown, when the indoor unit of the air conditioner in this embodiment is working, the fan blade unit 500 starts up, drawing indoor air in through the air inlet 300 on the main unit 200 and transporting it axially to the arc-shaped first guide surface 101 of the first guide housing 100. Under the guidance of the curved surface of the first guide surface 101, the airflow smoothly turns, and the flow direction gradually transitions from axial to the tangential direction of the guide surface. Then, it flows out through the annular first air outlet area 400 formed between the first guide housing 100 and the main unit 200 due to the movement of the first guide housing 100 away from the main unit 200. The airflow continues to diffuse because it adheres to the outer contour of the first guide surface 101, forming a low-speed, wide-angle airflow field without a direct blowing sensation.

[0073] Optionally, the outer wall surface of the first air guide housing 100 is a hemispherical surface.

[0074] The hemispherical outer wall allows the airflow to naturally expand along the tangent of the sphere after leaving the air outlet area, forming a symmetrical and wide-angle wall-attached airflow distribution. During cooling, the first air guide shell 100 moves downward, and the cold air adheres and diffuses upward along the outer wall of the hemispherical surface. During heating, it moves upward, and the hot air adheres and sinks downward along the outer wall of the hemispherical surface. The airflow has no separation or backflow on the hemispherical curved surface, minimizing resistance and further reducing noise. The uniformity of air outlet and coverage are enhanced due to geometric symmetry.

[0075] Furthermore, a sliding structure 102 is provided on the first air guide housing 100. The sliding structure 102 includes a sliding member 103, which is fixedly mounted on the first air guide housing 100. The sliding member 103 is provided with a sliding groove. Figure 5 As can be seen, the chute has a concave structure, and the main unit 200 includes:

[0076] The support body 201 has an air inlet 300 and a circular cross-section.

[0077] The mating structure 202 is disposed on the supporting body 201. The mating structure 202 includes a mating component 203. Specifically, the mating structure 202 is disposed on the inner wall of the supporting body 201, and the mating component 203 is provided with a slide rail, such as... Figure 9 As shown, the slide rail has a convex-shaped structure;

[0078] The sliding member 103 and the mating member 203 are slidably engaged so that the first air guide shell 100 moves relative to the supporting body 201.

[0079] Furthermore, a sliding structure 102 is provided on the first air guide housing 100. The sliding structure 102 includes a sliding member 103 fixed to the outer edge of the first air guide housing 100. A groove is machined on the inner side of the sliding member 103. The supporting body 201 of the main body unit 200 has a circular cross-section structure, and a mating structure 202 is provided circumferentially on its inner wall. The mating structure 202 includes a mating member 203 corresponding to the sliding member 103. A U-shaped slide rail is provided on the mating member 203. The groove of the sliding member 103 and the convex rail of the mating member 203 fit together to form a sliding fit relationship. When the first air guide housing 100 moves axially under the action of the driving mechanism, the groove slides along the convex rail, constraining the first air guide housing 100 to move only in a straight line along the axial direction of the supporting body 201, ensuring that the first air guide housing 100 and the supporting body 201 always maintain an annular gap, forming a stable and controllable first air outlet area 400. The concave-convex fit structure of the sliding structure 102 and the mating structure 202 has no radial offset during the movement, ensuring that the first air guide surface 101 is always coaxial with the axis of the fan blade unit 500, maintaining the continuity and symmetry of the airflow guide path.

[0080] Furthermore, the sliding structure 102 also includes a push mounting position 104, which is a mounting hole provided on the first air guide housing 100. The mating structure 202 also includes a push member 204, which is an electric push rod in this embodiment. The push member 204 is telescopically provided on one side of the mating member 203 along the movement direction of the first air guide housing 100. The push end of the push member 204 is used to be provided in the push mounting position 104 so that when the push member 204 is telescopically extended or retracted, the first air guide housing 100 slides relative to the supporting body 201.

[0081] Among them, such as Figure 13 As shown, the pushing end of the pushing member 204 is also provided with a pushing mounting rod 210. The pushing mounting rod 210 is fixedly connected to the pushing mounting position 104, thereby connecting the pushing end of the pushing member 204 to the first air guide housing 100. When the pushing member 204 extends or retracts, the pushing end can drive the first air guide housing 100 to move relative to the supporting body 201. In this embodiment, the pushing member 204 and the mating member 203 are provided separately.

[0082] Furthermore, the sliding structure 102 also includes a push mounting position 104 disposed on the first air guide housing 100. The push mounting position 104 is a mounting hole that penetrates at least a portion of the side wall of the first air guide housing 100. The mating structure 202 also includes an independently disposed push member 204, which is an electric push rod that is mounted on one side of the mating member 203 along the movement axis of the first air guide housing 100. Its push end is provided with a push mounting rod 210, which is inserted into and fixed in the push mounting position 104 to form a rigid connection.

[0083] When the pusher 204 extends or retracts, its push end directly drives the first air guide housing 100 to move linearly along the concave-convex slide rail structure of the sliding member 103 and the mating member 203 through the push mounting rod 210. The pusher 204 and the mating member 203 are arranged separately in space, and the installation position of the pusher 204 does not overlap with the slide rail structure to avoid motion interference. This ensures that the sliding fit between the sliding member 103 and the mating member 203 only undertakes the guiding function, and the pusher 204 only undertakes the driving force transmission, realizing the structural decoupling of power and guidance, so that the first air guide housing 100 maintains a stable and non-deflecting axial displacement during the extension and retraction process.

[0084] Furthermore, the sliding structure 102 also includes a push mounting position 104, which is a mounting hole provided on the first air guide housing 100. The mating structure 202 also includes a push member 204, which is an electric push rod in this embodiment. The mating member 203 is provided with a push mounting portion 105 extending along the movement direction of the first air guide housing 100. At least a portion of the push member 204 is located inside the push mounting portion 105, and the push end 205 of the push member 204 is located outside the push mounting portion 105 and connected to the push mounting position 104. The push mounting portion 105 is a mounting channel provided in the mating member 203, and at least a portion of the push member 204 is directly located in the mounting channel. The push end of the push member 204 is located inside the mounting channel.

[0085] Among them, such as Figure 13 As shown, the pushing end of the pushing member 204 is also provided with a pushing mounting rod 210. Both the pushing mounting rod 210 and the pushing end are located outside the installation channel. The pushing mounting rod 210 is fixedly connected to the pushing mounting position 104, thereby connecting the pushing end of the pushing member 204 to the first air guide housing 100. When the pushing member 204 extends or retracts, the pushing end can drive the first air guide housing 100 to move relative to the supporting body 201. In this embodiment, the pushing member 204 is set inside the mating member 203, and the two are not set separately.

[0086] Furthermore, the sliding structure 102 also includes a push mounting position 104, which is a mounting hole provided on the first air guide housing 100. The mating structure 202 includes a mating part 203, which is fixed to the inner wall of the support body 201. The mating part 203 has a push mounting portion 105 provided inside along the movement axis of the first air guide housing 100. The push mounting portion 105 is an axial mounting channel that passes through the mating part 203. The push part 204 is an electric push rod, the body of which is at least partially embedded in the push mounting portion 105. The push end 205 of the push part 204 extends out from the port of the push mounting portion 105 and extends to the outside of the channel. A push mounting rod 210 is fixedly connected to the push end 205. The push mounting rod 210 is inserted into and fixed in the push mounting position 104 of the first air guide housing 100 to form a rigid transmission connection.

[0087] When the pusher 204 extends or retracts within the push mounting part 105, its push end 205 directly pulls or pushes the first air guide housing 100 through the push mounting rod 210, causing the first air guide housing 100 to move axially in a straight line along the concave-convex slide rail structure of the sliding member 103 and the mating member 203. The body of the pusher 204 is constrained within the mounting channel of the mating member 203, and its movement direction is consistent with the guide direction of the slide rail. The pusher 204 and the mating member 203 are integrated structures with no relative displacement between them. The power transmission path is compact, avoiding interference from external drive mechanisms and ensuring the stability and coaxiality of the first air guide housing 100 during movement.

[0088] Furthermore, such as Figure 9 and Figure 14 As shown, the mating structure 202 also includes a clamping member 206, which is disposed on the push mounting portion 105. The clamping member 206 is provided with two clamping threaded holes, and the mating member 203 is provided with two mating threaded holes on the end face of the mating member 203 that is relatively close to the push end. The two clamping threaded holes are provided one-to-one with the two mating threaded holes so that the clamping member 206 is fixed to the mating member 203 by bolts. The clamping member 206 has a through hole 207, and at least a portion of the push member 204 passes through the through hole 207 and the push mounting portion 105 so that the push end 205 of the push member 204 is connected to the push mounting portion 104.

[0089] In this configuration, the pushing end of the pusher 204 and the pushing mounting rod 210 protrude through the through hole 207 to the outside of the mounting channel, while another part of the pusher 204 is located inside the mounting channel. The through hole 207 is only for the pushing end and the pushing mounting rod 210 to pass through, while... Figure 13 As can be seen, the diameter of the portion of the pusher 204 located within the mounting channel is larger than the diameter of the pusher end 205. Therefore, the clamping component 206 will also fix at least a portion of the pusher 204 within the mounting channel, preventing the pusher 204 from being separated from the mounting channel as a whole.

[0090] Furthermore, such as Figure 9 and Figure 14As shown, the mating structure 202 also includes a clamping component 206, which has two clamping threaded holes. The mating component 203 has two mating threaded holes on its end face near the pushing end. The clamping threaded holes correspond one-to-one with the mating threaded holes. The clamping component 206 is fastened to the end face of the mating component 203 by bolts. The clamping component 206 has a through hole 207 at its center, which is coaxially connected to the pushing mounting part 105. The body of the pushing component 204 passes through the pushing mounting part 105. Its pushing end 205 and the pushing mounting rod 210 fixed to the pushing end extend out of the mounting channel through the through hole 207 and are fixedly connected to the pushing mounting position 104 of the first air guide housing 100. The diameter of the part of the pusher 204 located inside the installation channel is larger than the diameter of the pusher end 205, forming a shoulder structure. The clamping component 206 is sleeved on the outer periphery of the pusher 204 through the through hole 207. Its inner diameter is smaller than the diameter of the shoulder, so that the clamping component 206 abuts against the shoulder end face of the pusher 204 after being tightened, axially confining the pusher 204 within the push mounting part 105, preventing it from coming out of the installation channel due to reaction force during the extension and retraction process. At the same time, the body of the pusher 204 maintains a gap with the inner wall of the installation channel, and axial positioning is achieved only through the clamping component 206, ensuring that the movement freedom of the pusher 204 is not restricted, and the driving force is transmitted to the first air guide housing 100 only through the pusher end and the push mounting rod 210.

[0091] Furthermore, such as Figure 8 As shown, the mating structure 202 also includes a limiting member 208, which is disposed in the push mounting portion 105 and located at the end of the push mounting portion 105 away from the pressing member 206. The limiting member 208 has a limiting surface 209 that cooperates with the push member 204 to limit the circumferential displacement of the push member 204 relative to the first air guide housing 100.

[0092] The limiting component 208 has a circular structure. The inner diameter of the limiting component 208 is smaller than the inner diameter of the push mounting part 105. The outer diameter of the limiting component 208 is adapted to the maximum outer diameter of the push member 204. The inner wall surface of the limiting component 208 is the limiting surface 209. During installation, the end of the push member 204 away from the push end is inserted into the limiting component 208, so that the bottom outer wall surface of the push member 204 is in contact with the limiting surface 209, thereby limiting the circumferential displacement of the push member 204 through the limiting surface 209.

[0093] Furthermore, such as Figure 8 As shown, the mating structure 202 also includes a limiting component 208. The limiting component 208 is a ring structure, which is disposed in the push mounting part 105 and located at the end away from the pressing component 206. The inner diameter of the limiting component 208 is smaller than the inner diameter of the push mounting part 105, and its outer diameter is adapted to the maximum outer diameter of the pusher 204. The inner wall surface of the limiting component 208 forms a limiting surface 209.

[0094] During installation, the non-push end of the pusher 204 is inserted into the push mounting part 105 from one end until its bottom outer wall is in contact with the limiting surface 209. The limiting surface 209 is a circumferentially continuous annular plane that is in full circumferential contact with the outer cylindrical surface at the bottom of the pusher 204, restricting the pusher 204 from circumferential rotation within the push mounting part 105. This ensures that the pusher 204 can only extend and retract axially, ensuring that the connection direction between the push end 205 and the push mounting rod 210 is always consistent with the axis of motion of the first air guide housing 100. This avoids the pusher 204 from deflecting due to torque transmission or the lateral stress generated by the sliding fit between the sliding member 103 and the mating member 203. The limiting member 208 and the pressing member 206 clamp the pusher 204 at both ends along the axial direction of the push mounting part 105, forming a dual constraint of axial positioning and circumferential anti-rotation, thus achieving stable fixation of the pusher 204 within the installation channel.

[0095] Furthermore, such as Figure 7 As shown, the indoor unit of the air conditioner also includes an evaporator 600, which is installed inside the support body 201;

[0096] A drainage structure 700 is installed on the support body 201 and located below the air inlet 300. The drainage structure 700 has a receiving surface 701, which is opposite to the water outlet of the evaporator 600, to receive the condensate generated by the evaporator 600 and guide it to the outside of the main body unit 200. The drainage structure 700 is an annular drainage groove installed on the support body 201, and the bottom end of the mating part 203 is installed in the annular drainage groove.

[0097] Furthermore, such as Figure 7 As shown, the indoor unit of the air conditioner also includes an evaporator 600, which is located inside the support body 201 and upstream of the fan blade unit 500, for heat exchange with the intake air.

[0098] The drainage structure 700 is located at the bottom of the support body 201, below the air inlet 300. It is an annular drainage groove arranged circumferentially around the inner wall of the support body 201. The drainage groove has an upward-opening receiving surface 701, which is directly opposite the condensate outlet of the evaporator 600. It is used to receive and collect the condensate generated during the operation of the evaporator 600. The annular drainage groove is inclined circumferentially to guide the condensate to the drain outlet and to the outside of the main body unit 200. The bottom end of the mating part 203 is embedded and fixed in the annular drainage groove. It is sealed and fitted with the groove wall of the drainage groove, so that the mating part 203 simultaneously completes the sealing and structural support of the upper edge of the drainage groove during installation. This ensures that the condensate can only be discharged directionally through the drainage groove, avoiding seepage into the area of ​​the push mounting part 105 or the sliding structure 102, and keeping the electric push rod and sliding mating parts dry and reliable in operation.

[0099] Furthermore, the indoor unit of the air conditioner also includes a second air guide casing 800;

[0100] The second air guide housing 800 has an arc-shaped second air guide surface 801. The second air guide housing 800 is movably arranged so that when the second air guide housing 800 moves toward the side away from the main unit 200, a second air outlet area is formed between the second air guide housing 800 and the main unit 200.

[0101] The fan blade unit 500 is also used to guide the airflow from the air inlet 300 to the second guide surface 801 for guidance, so that the guided airflow flows out from the second air outlet area.

[0102] The structure of the second air guide housing 800 is the same as that of the first air guide housing 100. The second air guide housing 800 and the first air guide housing 100 are located on opposite sides of the support body 201. The second air guide housing 800 also has a push mounting position 104 and a sliding structure 102. The support body 201 also has a mating structure 202 that cooperates with the sliding structure 102. The difference between the second air guide housing 800 and the structure on the first air guide housing 100 is that the pushing end of the pusher 204 that cooperates with the second air guide housing 800 has a different orientation. Figure 1 As shown, the pushing ends of the two pushing members 204 are arranged oppositely. The pushing member 204 with its pushing end located above is adapted to the first air guide housing 100. Correspondingly, the clamping member 206 is provided at one end of the pushing mounting portion 105 near the pushing end, or the clamping member 206 is provided at both ends of the pushing mounting portion 105, one end for the pushing end to extend out, and the other end for fixing the tail of the pushing member 204 (i.e., the end away from the pushing end). The pushing member 204 with its pushing end located below is adapted to the second air guide housing 800. Correspondingly, the clamping member 206 is provided at the other end of the pushing mounting portion 105 near the pushing end. One end, or the pressing component 206, is provided at both ends of the push mounting part 105. One end is used for the push end to extend, and the other end is used to fix the tail of the push member 204 (that is, the end away from the push end). This enables the first air guide housing 100 and the second air guide housing 800 to move away from each other. In this embodiment, the push end of the push member 204 corresponding to the first air guide housing 100 faces upward, and its corresponding pressing component 206 is provided on the push end. The push end of the push member 204 corresponding to the second air guide housing 800 faces downward, and its corresponding pressing component 206 is provided on the tail of the push member 204.

[0103] The indoor unit of the air conditioner also includes a second air guide housing 800, which has the same structure as the first air guide housing 100. Both have spherical arc-shaped air guide surfaces (second air guide surface 801 and first air guide surface 101), and are respectively arranged on the upper and lower sides of the supporting body 201. The second air guide housing 800 can move along the axial direction. When it moves downward away from the main body unit 200, a second air outlet area is formed between it and the main body unit 200. After the fan blade unit 500 introduces the airflow from the air inlet 300, it is guided by the second air guide surface 801, so that the airflow flows out from the second air outlet area.

[0104] The second air guide housing 800 is provided with the same push mounting position 104 and sliding structure 102 as the first air guide housing 100, and the support body 201 is provided with a matching structure 202. The push member 204 matched with the first air guide housing 100 has its push end facing upward, and the pressing member 206 is provided on one side of the push end of the push member 204 to fix the push end and limit its position. The push member 204 matched with the second air guide housing 800 has its push end facing downward, and the pressing member 206 is provided at the tail of the push member 204 (on the side away from the push end) to fix the end of the push member 204 and realize reverse thrust transmission, so that the first air guide housing 100 and the second air guide housing 800 can move in opposite directions respectively, realizing the independent opening and closing of the upper and lower air outlet areas.

[0105] like Figure 1 As shown, two mating structures 202 are provided on the support body 201. A clearance groove is provided on the drainage structure 700 at a position corresponding to the two mating structures 202. The clearance groove allows the sliding structure 102 to slide and engage with the mating structures 202. To prevent condensate generated by the evaporator 600 from flowing out of the two clearance grooves during operation and affecting the engagement between the mating structures 202 and the sliding structure 102, a clearance area is provided on the evaporator 600, such as... Figure 6 As shown, the circumferential width of the avoidance zone is greater than the circumferential distance between the two mating structures 202, that is, both mating structures 202 are located within... Figure 6 Within the clearance zone described above, the condensate produced by the evaporator 600 will not drip into the two clearance grooves, thus not affecting the sliding structure 102 and the mating structure 202. Therefore, it can be ensured that during the normal operation of the air conditioner, the movement of the first air guide housing 100 and the second air guide housing 800 relative to or away from the support body 201 will not be affected.

[0106] Furthermore, the indoor unit of the air conditioner also includes a protective component 900, which is disposed on the main unit 200 and located between the fan blade unit 500 and the second air guide housing 800. The protective component 900 is provided with an overflow channel 901 so that the airflow at the air inlet 300 enters the second air guide surface 801 through the overflow channel 901. The protective component 900 is a protective net.

[0107] Furthermore, the indoor unit of the air conditioner also includes a protective component 900, which is disposed on the main unit 200 and located between the fan blade unit 500 and the second air guide housing 800;

[0108] The protective component 900 is a mesh structure made of metal or engineering plastic. It is circumferentially fixed to the inner wall of the support body 201 and maintains a safe distance from the rotation radius of the fan blade unit 500. The protective component 900 has multiple evenly distributed flow channels 901. The size and shape of the flow channels 901 are adapted to the airflow requirements, so that the airflow drawn in from the air inlet 300 can pass through the flow channels 901 without obstruction after being accelerated by the fan blade unit 500 and enter the second guide surface 801 area of ​​the second air guide housing 800. While ensuring smooth airflow, the protective component 900 effectively prevents foreign objects or human bodies from contacting the high-speed rotating fan blade unit 500, improving the safety of use. Its mesh structure has minimal disturbance to the airflow and does not affect the guiding efficiency and uniformity of the airflow on the second guide surface 801.

[0109] Furthermore, the fan blade unit 500 includes a drive element 501 disposed on the side of the protective component 900 of the air conditioner indoor unit away from the second air guide housing 800, and the drive element 501 has a drive end;

[0110] An axial flow fan blade 502 is disposed on the drive end to introduce airflow from the air inlet 300 to the first guide surface 101 and / or the second guide surface 801 through the drive element 501, wherein the drive element 501 is a motor.

[0111] Furthermore, the fan unit 500 includes a drive element 501 and an axial fan blade 502. The drive element 501 is a permanent magnet synchronous motor, located on the side of the protective component 900 away from the second air guide housing 800. Its motor housing is fixedly connected to the motor mounting base on the inner wall of the support body 201 by bolts or clips. The drive end of the drive element 501 extends axially, and the axial fan blade 502 is directly coaxially assembled on the drive end, so that the rotation axis of the fan blade coincides with the central axis of the first air guide housing 100 and the second air guide housing 800. After the drive element 501 is energized, it drives the axial fan blade 502 to rotate, drawing outside air from the outside. The air inlet 300 draws in air axially, and after being rectified by the flow channel 901 of the protective component 900, it is evenly guided into the first guide surface 101 or the second guide surface 801. This achieves dual-mode axial air outlet, where the airflow is guided downward through the first guide surface 101 during cooling and upward through the second guide surface 801 during heating. The axial fan blade 502 and the drive element 501 form an integrated fan assembly with a compact structure, high transmission efficiency, no belt or gear transmission losses, and low operating noise. Furthermore, its axial air outlet characteristics are highly matched with the geometry of the spherical guide surface, significantly reducing vortex separation and aerodynamic resistance, and improving the overall energy efficiency ratio and air delivery uniformity.

[0112] Furthermore, such as Figure 15 As shown, the air conditioner indoor unit also includes a mounting component 902, which is detachably mounted on the main unit 200 to mount the air conditioner indoor unit on the mounting base.

[0113] The mounting component 902 is a mounting plate with multiple first threaded holes and multiple second threaded holes on the main unit 200 at corresponding positions. The multiple first threaded holes and multiple second threaded holes are arranged one-to-one to fix the main unit 200 to the mounting component 902 with bolts, and to fix the air conditioner indoor unit as a whole to the mounting base through the mounting component 902. The mounting base can be a wall.

[0114] Furthermore, such as Figure 15 As shown, the indoor unit of the air conditioner also includes a mounting component 902, which is a mounting plate made of metal or high-strength engineering plastic, and is detachably mounted on the bottom of the outer periphery of the main unit 200. The mounting component 902 has a plurality of first threaded holes, and the corresponding positions of the main unit 200 have matching second threaded holes. The two are fastened by countersunk bolts, so as to realize the quick assembly and reliable fixation between the main unit 200 and the mounting component 902.

[0115] Furthermore, this application embodiment also provides an air conditioner, which includes an indoor unit and an outdoor unit, wherein the indoor unit is the aforementioned indoor unit.

[0116] Furthermore, this application embodiment also provides a control method for an air conditioner indoor unit, which is applicable to the above-mentioned air conditioner indoor unit. The control method includes generating a corresponding operation command in response to a user's operation request.

[0117] According to the operation instructions, when the operating mode of the indoor unit of the air conditioner is determined to be either cooling mode or heating mode, the first air guide housing 100 of the indoor unit of the air conditioner is controlled to move away from the main unit 200 of the indoor unit of the air conditioner to form the first air outlet zone 400; wherein, when in heating mode, the first air guide housing 100 moves upward.

[0118] The control fan unit 500 introduces airflow from the air inlet 300 of the main unit 200 to the first guide surface 101 of the first guide housing 100 for guidance, so that the guided airflow flows out from the first air outlet area 400.

[0119] Furthermore, after the step of directing the airflow to exit from the first outlet zone 400, the control method further includes:

[0120] Obtain the user's real-time body temperature;

[0121] When the real-time perceived temperature exceeds a preset temperature range, the first air guide housing 100 is controlled to move closer to the support body 201, that is, to reduce the distance between the first air guide housing 100 and the support body 201; and / or,

[0122] When the real-time perceived temperature is within the preset temperature range, the first air guide housing 100 is controlled to maintain its current position.

[0123] When the indoor unit of the air conditioner enters the heating mode in response to the user's command, the electric actuator drives the first air guide housing 100 to move upward away from the main unit 200, forming the upper first air outlet area 400. The axial flow fan blades 502 of the fan blade unit 500 draw in air through the air inlet 300. After being heated by the evaporator 600, the airflow is guided along the spherical arc surface of the first guide surface 101 and sent upward from the first air outlet area 400. During the air outlet process, the system obtains the user's perceived temperature in real time. When the temperature is detected to be higher than the preset temperature range (e.g., higher than 27°C), the system controls the first air guide housing 100 to move closer to the support body 201, reducing the air outlet gap between it and the support body 201. This causes the hot air to turn downward under the guidance of the spherical arc surface and the small gap jet, preventing the hot air from rising excessively and causing overheating of the head. When the perceived temperature is within the preset temperature range, the first air guide housing 100 maintains its current position, maintaining a stable upward air outlet state.

[0124] Furthermore, the control method also includes controlling the second air guide housing 800 of the air conditioner indoor unit to move away from the main unit 200 when the operating mode of the air conditioner indoor unit is determined to be either cooling mode or heating mode according to the operation command, so as to form a second air outlet zone; wherein, when in cooling mode, the second air guide housing 800 moves downward.

[0125] The control fan unit 500 introduces airflow from the air inlet 300 of the main unit 200 to the second guide surface 801 of the second guide housing 800 for guidance, so that the guided airflow flows out from the second air outlet area.

[0126] Furthermore, after the step of guiding the airflow to exit from the second outlet zone, the control method further includes:

[0127] Obtain the user's real-time body temperature;

[0128] When the real-time perceived temperature is lower than the preset temperature range, the second air guide housing 800 is controlled to move closer to the support body 201, that is, to reduce the distance between the second air guide housing 800 and the support body 201; and / or,

[0129] When the real-time perceived temperature is within the preset temperature range, the second air guide housing 800 is controlled to maintain its current position.

[0130] When the indoor unit of the air conditioner enters the cooling mode in response to the user's command, the electric actuator drives the second air guide housing 800 to move downward away from the main unit 200, forming the lower second air outlet area. The axial flow fan blades 502 of the fan blade unit 500 draw in air through the air inlet 300. After being cooled by the evaporator 600, the airflow is guided along the spherical arc surface of the second guide surface 801 and sent downward from the second air outlet area. During the air outlet process, the system obtains the user's perceived temperature in real time. When the temperature is detected to be lower than the preset temperature range (such as lower than 24°C), the system controls the second air guide housing 800 to move closer to the supporting main body 201, reducing the air outlet gap between it and the main body. This causes the cold air to turn upward under the guidance of the spherical arc surface and the small gap jet action, preventing the cold air from blowing directly on the human body. When the perceived temperature is within the preset temperature range, the second air guide housing 800 maintains its current position and maintains a stable downward air outlet state.
