Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to wall-mounted air conditioner indoor units. Background Technology

[0002] As people's requirements for the air delivery performance of air conditioners increase, some wall-mounted air conditioner indoor units use push rods to push the air guide plate a certain distance, and then use a rotary motor to drive the air guide plate to rotate. This expands the coverage of the air delivery plate, so that the cool or warm air can be delivered to all corners of the room more evenly, reducing the unevenness of indoor temperature, improving the cooling / heating efficiency of the air conditioner, and also allowing the air guide plate to have a wider range of rotation angles. This allows users to adjust the air delivery direction and angle more flexibly to meet personalized air delivery needs.

[0003] Currently, some wall-mounted air conditioner indoor units have the rotary motor located at the end of the push rod extending from the casing. This means that the length of the motor's cable changes during the push rod's extension or retraction, requiring it to lengthen or shorten accordingly. If the cable redundancy is too low, it cannot meet the motor's cable length requirements after the push rod is extended, causing the motor to malfunction. If the cable redundancy is too high, on the one hand, the redundant cable may become entangled with the components driving the push rod, affecting not only the normal rotation of the air guide plate but also potentially damaging the rotary motor and the components driving the push rod, reducing the air conditioner's lifespan. On the other hand, the entangled cable can also pose safety hazards, such as short circuits or open circuits, threatening the user's electrical safety. Utility Model Content

[0004] To address the shortcomings of related technologies, this application provides a wall-mounted air conditioner indoor unit that incorporates a cable routing gear inside a push rod and a rack along the push rod's movement trajectory. The cable routing gear and rack work together to rotate synchronously with the push rod's movement, thereby winding or unwinding the motor cable of the rotating motor. This allows the length of the motor cable to be adjusted according to the push rod's movement, meeting the push rod's motion requirements.

[0005] This application provides a wall-mounted air conditioner indoor unit, including:

[0006] The casing has an air inlet on the top and an air outlet on the lower front side.

[0007] The heat exchanger is located inside the casing, with at least part of the heat exchanger facing the air inlet of the casing.

[0008] The heat exchange fan is located inside the casing, with its axis running along the length of the casing; the heat exchange fan is located on the leeward side of the heat exchanger.

[0009] An air guide plate is rotatably mounted at the air outlet of the casing; the axis of rotation of the air guide plate is set along the length of the casing.

[0010] The push rod can reciprocate in a straight line to drive the air guide plate to push out in a direction away from the air outlet of the housing or retract in a direction close to the air outlet of the housing; one end of the push rod is located inside the housing, and the other end of the push rod extends out of the housing and can reciprocate in a straight line; the end of the push rod extending out of the housing is connected to the air guide plate.

[0011] A rotary motor is installed at one end of the push rod connected to the air guide plate. The motor shaft of the rotary motor is connected to one end of the air guide plate along its length and is used to drive the air guide plate to rotate.

[0012] The cable guide gear is rotatably connected to the push rod, and the motor wire of the rotating motor is wound around the cable guide gear;

[0013] The rack is located inside the housing. The rack extends along the movement trajectory of the push rod and is located on the side where the push rod extends in the direction of its movement. The rack meshes with the cable guide gear.

[0014] When the push rod moves linearly, the wire-carrying gear rotates synchronously under the action of the rack to wind up or unwind the motor wire of the rotary motor.

[0015] This technical solution adjusts the length of the motor cable by incorporating a cable-carrying gear on the push rod, allowing the motor cable to be wound or released. Furthermore, a rack is installed along the push rod's trajectory, with the outer edge of the cable-carrying gear meshing with it through a channel. This causes the cable-carrying gear to rotate along with the push rod's linear movement, enabling the winding and unwinding of the motor cable. This allows the length of the motor cable to be adjusted according to the push rod's movement, preventing excessive cable redundancy that could lead to tangling, and also preventing insufficient cable redundancy that could prevent the rotary motor from connecting to the power supply.

[0016] In some embodiments, when the wire-carrying gear rotates one revolution, the change in the motor wire is d1, and the linear movement distance of the push rod is d2. d1 and d2 satisfy the relationship: d1 = d2.

[0017] This technical solution ensures that the change in the motor wire during one revolution of the wire-carrying gear is the same as the movement distance of the push rod, so that the change in the motor wire changes synchronously with the movement distance of the push rod, thereby satisfying the movement requirements of the push rod.

[0018] In some embodiments, the wire-carrying gear is provided with a winding portion, the winding portion is provided with a wire-carrying portion, the wire-carrying portion is provided to pass through the winding portion radially, and the motor wire of the rotating motor passes through the wire-carrying portion and is wound around the winding portion.

[0019] This technical solution provides a wiring section in the winding section, which runs radially through the winding section to circumferentially constrain the motor wire, preventing relative sliding between the motor wire and the winding section along the circumference of the winding section and ensuring the winding effect of the motor wire in the winding section.

[0020] In some embodiments, the wiring section is provided to pass through one end of the winding section along the axial direction of the winding section to form an inlet and outlet section for the power supply line in the wiring section.

[0021] This technical solution allows the motor wires to be routed from the inlet / outlet section into the wiring section.

[0022] In some embodiments, the winding portion is connected to a cover, which is located on the side of the winding portion where the inlet and outlet are located, and is used to block the inlet and outlet.

[0023] This technical solution uses a cover to block the inlet and outlet, thereby preventing the motor wires located in the wiring section from detaching from the wiring section.

[0024] In some embodiments, a first protrusion is provided on the side of the cover facing the winding portion, the first protrusion extends radially along the cover, and the first protrusion is provided in the wiring portion through an inlet / outlet portion.

[0025] This technical solution provides a first protrusion in the cover, which is located inside the wiring section from the inlet / outlet section. This can constrain the axial dimension of the wiring section along the winding section, reducing the range of motion of the motor wire in the wiring section. On the other hand, it can also position the connection between the cover and the winding section.

[0026] In some embodiments, the winding portion is provided with a recessed portion, which is recessed in the side of the winding portion facing the cover, and the extending direction of the recessed portion intersects with the setting direction of the wiring portion; the side of the cover facing the winding portion is provided with a second protrusion, which is located in the recessed portion.

[0027] This technical solution provides a recessed portion in the winding section and a second protrusion in the cover, with the second protrusion located within the recessed portion to further position the connection between the cover and the winding section.

[0028] In some embodiments, a channel is defined inside the push rod, extending along the direction of movement of the push rod; the rotating motor and the wire-guided gear are disposed in the channel, and the outer edge of the wire-guided gear extends out of the channel and meshes with the rack.

[0029] This technical solution sets up a channel inside the push rod, allowing the rotary motor to be placed inside the channel and its motor wires to run through the channel. On the one hand, the channel can constrain the motor wires to a certain extent, and on the other hand, it can protect the motor wires.

[0030] In some embodiments, the side wall of the push rod is provided with an extension for the outer edge of the wire-carrying gear to extend out of the channel, and the rack is located on the side of the push rod where the extension is provided.

[0031] This technical solution involves placing the rack on one side of the push rod extension so that the cable routing gear can mesh with the rack when it extends from the extension outside the channel.

[0032] In addition, this application also provides a wall-mounted air conditioner indoor unit, comprising:

[0033] The casing has an air inlet on the top and an air outlet on the lower front side.

[0034] The heat exchanger is located inside the casing, with at least part of the heat exchanger facing the air inlet of the casing.

[0035] The heat exchange fan is located inside the casing and is positioned along the length of the casing; the heat exchange fan is located on the leeward side of the heat exchanger.

[0036] An air guide plate is rotatably mounted at the air outlet of the casing; the axis of rotation of the air guide plate is set along the length of the casing.

[0037] A rotary motor, the motor shaft of which is connected to one end of the guide plate along its length, is used to drive the guide plate to rotate;

[0038] The ejection assembly is used to drive the air guide plate to extend away from the air outlet of the housing or retract towards the air outlet of the housing; the ejection assembly includes:

[0039] Mechanism box, the mechanism box is located inside the machine housing;

[0040] The push rod has its connecting end inside the mechanism box and its telescopic end outside the machine housing; the rotary motor and the air guide plate are respectively located at the telescopic end of the push rod; the push rod reciprocates along a straight line.

[0041] The crank is located inside the mechanism housing and is connected to the push rod, used to drive the push rod to linear motion.

[0042] A winding assembly for winding the motor wire of a rotary electric motor; the winding assembly includes:

[0043] The rack is located inside the mechanism box, extending along the movement trajectory of the push rod and situated on the side where the push rod extends in the direction of its movement.

[0044] The wire-carrying gear is located inside the push rod. The motor wire of the rotating motor is wound around the wire-carrying gear, and part of the outer edge of the wire-carrying gear passes through the inner wall of the push rod and meshes with the rack.

[0045] When the push rod moves linearly, the wire-carrying gear rotates synchronously to wind up or unwind the motor wire of the rotary motor.

[0046] This technical solution incorporates a crank connected to a push rod. The crank's rotation drives the push rod in linear motion, causing it to push the air guide plate away from the air outlet or retract it towards the air outlet. A cable-carrying gear is installed inside the push rod, winding the motor cable around it. This allows for cable winding and unwinding, thus adjusting the cable length. A rack is placed along the push rod's trajectory, with the outer edge of the cable-carrying gear meshing with it. As the push rod moves, the rack's action causes the cable-carrying gear to rotate, further winding and unwinding the motor cable. This allows the cable length to be adjusted with the push rod's movement, preventing excessive cable redundancy that could lead to tangling, and also preventing insufficient cable redundancy that could prevent the rotary motor from connecting to the power supply.

[0047] In the above embodiment, the indoor unit of the wall-mounted air conditioner has a rotary motor installed on the telescopic end of the push rod, so that the motor wire of the rotary motor runs through the inside of the push rod. A wire-carrying gear is set in the push rod, and the motor wire is wound around the wire-carrying gear. A rack is set in the movement trajectory of the push rod, so that the wire-carrying gear meshes with the rack. When the push rod moves, the wire-carrying gear rotates with the linear movement of the push rod under the action of the rack, thereby realizing the winding and unwinding of the motor wire. This allows the length of the motor wire to be adjusted with the movement of the push rod, preventing excessive motor wire redundancy that would cause the motor wire to become tangled, and also preventing insufficient motor wire redundancy that would prevent the rotary motor from connecting to the power supply.

[0073] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0074] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0075] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0076] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0077] The wall-mounted air conditioner indoor unit provided in this application can have various implementation forms. For example, it can be a wall-mounted air conditioner indoor unit with a fresh air function, or it can be a wall-mounted air conditioner indoor unit without a fresh air function. Figures 1-3 This is one specific implementation of the wall-mounted air conditioner indoor unit of this application.

[0078] like Figure 1As shown, the housing 100 is used to form the overall appearance of the indoor unit of the air conditioner. The housing 100 has a top and a bottom. The top and bottom of the housing 100 are opposite ends. The height direction of the housing 100 is from the top to the bottom. The left and right sides of the housing 100 are opposite sides. The length direction of the housing 100 is from the left to the right. The front and rear sides of the housing 100 are opposite sides. The thickness direction of the housing 100 is from the front to the rear.

[0079] In practical applications, the housing 100 is usually installed on the ceiling or in the upper space of an interior room, with the rear of the housing 100 facing the wall and the front of the housing 100 facing the user.

[0080] The housing 100 has a first cavity defined inside, which extends along the length of the housing 100; the housing 100 has a housing air inlet 101, which is located at the top of the housing 100 and communicates with the first cavity, allowing indoor air to enter the first cavity through the housing air inlet 101.

[0081] The air inlet 101 extends along the length of the housing 100 to give it a larger size, thereby allowing the indoor unit of the air conditioner to have a larger air intake volume.

[0082] like Figure 2 As shown, a housing air outlet 102 is formed on the housing 100. The housing air outlet 102 is located on the front side of the housing 100 and near the bottom of the housing 100. That is, the housing air outlet 102 is located on the lower front side of the housing 100. The housing air outlet 102 is connected to the first cavity, and the air in the first cavity is output to the room through the housing air outlet 102.

[0083] The air outlet 102 extends along the length of the housing 100 to give the air outlet 102 a larger size, thereby giving the indoor unit of the air conditioner a larger air volume.

[0084] like Figure 3 As shown, the indoor unit of the wall-mounted air conditioner includes a heat exchanger 600, which is disposed in a first cavity and is used to exchange heat with the air passing through it to form air conditioning air to meet the user's cooling or heating needs. The heat exchanger 600 is located near the air inlet 101 of the casing, and at least a portion of the air-facing side of the heat exchanger 600 faces the air inlet 101 of the casing so that the air entering the first cavity can come into contact with the heat exchanger 600 as quickly as possible.

[0085] It should be noted that air conditioning can produce cold air, hot air, or even air at room temperature.

[0086] like Figure 2As shown, the indoor unit of the wall-mounted air conditioner includes a heat exchange fan 300, which is disposed in a first cavity and is used to introduce indoor air into the first cavity and / or output air from the first cavity to the room. The axial direction of the heat exchange fan 300 is arranged along the length of the casing 100, and the heat exchange fan 300 is located on the leeward side of the heat exchanger 600, with a portion of the heat exchanger 600 located above the heat exchange fan 300.

[0087] The heat exchange fan 300 operates to draw indoor air into the first chamber through the air inlet 101 of the casing. After heat exchange by the heat exchanger 600, the air is conditioned and then output to the room through the air outlet 102 of the casing.

[0088] It should be noted that in the indoor unit of a wall-mounted air conditioner, the heat exchange fan 300 is usually a cross-flow fan.

[0089] like Figure 1 As shown, a guide vane 200 is provided at the air outlet 102 of the housing. The guide vane 200 is rotatably connected to the air outlet 102 of the housing to open or close the air outlet 102. In addition, the guide vane 200 can also guide the air output from the air outlet 102 to the room, or adjust the air outlet angle and direction of the air outlet 102. The rotation axis of the guide vane 200 is set along the length of the housing 100.

[0090] like Figure 2 and Figure 3 As shown, the indoor unit of the wall-mounted air conditioner includes a push-out assembly for driving the air guide plate 200 to push out in a direction away from the air outlet 102 of the casing or to retract in a direction closer to the air outlet 102 of the casing, so that the air guide plate 200 has a wider range of rotation angles.

[0091] In some embodiments, when the indoor unit of the wall-mounted air conditioner is running, the air guide plate 200 is first extended and then rotated; when the indoor unit of the wall-mounted air conditioner is not running, the air guide plate 200 is first rotated to reset and then retracted. This is a conventional technical means in the art and will not be described in detail here.

[0092] like Figures 2-5 As shown, the ejection assembly includes a push rod 400. One end of the push rod 400 is located inside the housing 100, and the other end of the push rod 400 is located outside the housing 100. The end of the push rod 400 located outside the housing 100 is connected to the air guide plate 200. The push rod 400 is used to push the air guide plate 200 out in a direction away from the air outlet 102 of the housing or to retract the air guide plate 200 in a direction close to the air outlet 102 of the housing.

[0093] like Figure 4 and Figure 5As shown, the ejection assembly includes a mechanism box 700, which is located inside the housing 100. The mechanism box 700 is used to install or accommodate one end of the push rod 400 located inside the housing 100.

[0094] The mechanism box 700 is provided with a through part for the push rod 400 to extend out of the mechanism box 700, so that one end of the push rod 400 is located inside the mechanism box 700 and the other end of the push rod 400 is located outside the mechanism box 700.

[0095] like Figure 6 As shown, the mechanism box 700 is provided with a rolling element 730. The rolling element 730 is located inside the mechanism box 700 and near the protruding part. The rolling element 730 is located on both sides of the movement trajectory of the push rod 400. The rolling element 730 is in contact with the push rod 400 to guide the movement of the push rod 400.

[0096] In some embodiments, the rolling element 730 is a roller, and when the push rod 400 moves, the roller rolls to reduce the friction between the push rod 400 and the rolling element 730.

[0097] For ease of description, the end of the push rod 400 located inside the mechanism box 700 is the connecting end of the push rod 400, and the end of the push rod 400 located outside the mechanism box 700 is the telescopic end of the push rod 400. The connecting end and the telescopic end are respectively located at the two ends of the push rod 400 along its length.

[0098] In some embodiments, a second cavity is formed inside the housing 100, and the second cavity is distributed along the length of the housing 100 with the first cavity. The second cavity is used to accommodate the mechanism box 700. The first cavity and the second cavity are separated from each other to prevent air in the first cavity that has been heated by the heat exchanger 600 from entering the second cavity, which may not only affect the operation of the ejection assembly, but also reduce the heat exchange efficiency of the heat exchanger 600.

[0099] It should be noted that the cavity wall of the second cavity is provided with a through part, which communicates with the second cavity. The through part is provided in correspondence with the through part, so that the push rod 400 extends out of the housing 100 from the through part.

[0100] In some embodiments, the through portion is an opening located on the lower front side of the housing 100, and the through portion and the housing air outlet 102 are distributed along the length direction of the housing 100.

[0101] like Figure 6 and Figure 7 As shown, the ejection assembly includes a crank 900, which is located inside and rotatably connected to the mechanism box 700. The crank 900 is used to drive the push rod 400 to reciprocate linearly to eject or retract the air guide plate 200.

[0102] like Figure 6As shown, the connecting end of the push rod 400 is provided with a first connecting part 401, and the outer edge of the crank 900 is provided with a second connecting part. The second connecting part is slidably connected to the first connecting part 401 so that the crank 900 is connected to the push rod 400, thereby driving the push rod 400 to move.

[0103] When the crank 900 rotates, it will drive the second connecting part to move. The second connecting part is connected to the first connecting part 401. The first connecting part 401 is located on the push rod 400. Therefore, when the second connecting part moves, it will drive the push rod 400 to move.

[0104] Since the second connecting part is located at the outer edge of the crank 900, when the crank 900 rotates, the second connecting part will move along an arc curve. The trajectory of the second connecting part is located on a circle S with the rotation center of the crank 900 as the center and the distance from the second connecting part to the rotation center of the crank 900 as the radius. The trajectory of the second connecting part is a part of the circle S.

[0105] Since the second connecting part moves along an arc curve while the push rod 400 reciprocates along a straight line, by placing the second connecting part inside the first connecting part 401 and sliding it along the first connecting part 401, interference between the movement of the second connecting part and the movement of the push rod 400 can be prevented.

[0106] The arc-shaped motion of the second connecting part is decomposed into the linear motion of the second connecting part driving the push rod 400 and the sliding of the second connecting part along the first connecting part 401.

[0107] It should be noted that the first connecting part 401 has a first position and a second position, and the second connecting part slides back and forth linearly between the first position and the second position to push out or retract the push rod 400. It should be noted that the first position and the second position correspond to the two endpoints of the arc-shaped trajectory of the second connecting part.

[0108] like Figure 4 and Figure 5 As shown, the ejector assembly includes a drive motor 800, which drives the crank 900 to rotate; the drive motor 800 is mounted on the mechanism housing 700.

[0109] The drive motor 800 drives the crank 900 to rotate, so that the crank 900 drives the push rod 400 to move linearly, thereby realizing the extension and retraction of the air guide plate 200. By utilizing the motion principle of the crank-puss mechanism, not only can the stability of the push rod 400 during the motion process be increased, but the push rod 400 can also have a large load-bearing capacity, enabling the push rod 400 to drive the large-sized air guide plate 200 to move. Furthermore, the push rod 400 has low noise and high reliability during the motion process.

[0110] In some embodiments, the drive motor 800 is located outside the mechanism box 700, and the motor shaft of the drive motor 800 extends into the mechanism box 700 and is connected to the crank 900 to drive the crank 900 to rotate.

[0111] In other embodiments, such as Figure 12 As shown, the motor shaft of the drive motor 800 is connected to a drive gear 810, which is located inside the mechanism housing 700. The outer edge of the crank 900 is provided with teeth that mesh with the drive gear 810. The drive motor 800 drives the crank 900 to rotate through the drive gear 810, so that the drive motor 800 can have a large driving force.

[0112] The working principle of the ejection component is as follows: the drive motor 800 drives the crank 900 to rotate through the drive gear 810, the second connecting part rotates synchronously with the crank 900, the second connecting part slides along the first connecting part 401, and at the same time the second connecting part drives the push rod 400 to move linearly in the first direction, so that the push rod 400 retracts the air guide plate 200 in the direction close to the air outlet 102 of the housing or pushes the air guide plate 200 out in the direction away from the air outlet 102 of the housing.

[0113] Since the second connecting part moves along an arc-shaped trajectory, in order to ensure that the push rod 400 moves in a straight line, such as Figure 6 As shown, this application provides a guide portion 711 on the mechanism box 700, and the guide portion 711 extends along the linear movement direction of the push rod 400; as Figure 7 As shown, the connecting end of the push rod 400 is connected to a limiting member 410. The limiting member 410 is located in the guide portion 711 and slides along the guide portion 711 to guide the movement of the push rod 400 and limit the movement trajectory of the push rod 400, ensuring that the push rod 400 moves reliably in a straight line.

[0114] In some embodiments, the inner wall of the guide portion 711 is provided with limiting ribs, which are arranged along the extending direction of the guide portion 711; such as Figure 9 As shown, the limiting member 410 is provided with a recess 411, which is recessed into the peripheral wall of the limiting member 410 along the circumference of the limiting member 410. A limiting rib is provided in the recess 411 to prevent the limiting member 410 from disengaging from the guide part 711. In addition, the limiting rib can also limit and constrain the axial direction of the limiting member 410, thereby limiting and constraining the push rod 400 along the axial direction of the limiting member 410 and preventing the push rod 400 from moving in the axial direction of the limiting member 410.

[0115] To facilitate the connection of the crank 900, the drive gear 810, and the push rod 400 within the mechanism box 700, the mechanism box 700 is designed as a split structure.

[0116] like Figure 6As shown, the mechanism box 700 includes a first box 710, and a guide 711 is disposed in the first box 710. As... Figure 7 As shown, the mechanism box 700 includes a second box 720, which is spliced ​​with the first box 710.

[0117] It should be noted that after connecting the push rod 400, crank 900, and drive gear 810 to the first box 710, the first box 710 is then connected to the second box 720.

[0118] like Figure 6 As shown, the first box 710 is provided with a first ear 712, which is located on the outer edge of the first box 710. The first ear 712 is located outside the mechanism box 700, and the first ear 712 is connected to the second box 720 by fasteners such as bolts or screws.

[0119] like Figure 7 As shown, the second box 720 is provided with a second ear 721, which is located on the outer edge of the second box 720. The second ear 721 is located outside the mechanism box 700. The second ear 721 is correspondingly provided with the first ear 712. The second ear 721 and the first ear 712 are connected by fasteners such as bolts or screws to realize the splicing of the second box 720 and the first box 710.

[0120] In some embodiments of this application, two ejection components are configured, with the two ejection components located at opposite ends of the guide plate 200 along its length, so that the guide plate 200 is subjected to uniform force and the smoothness of the ejection and retraction movements of the guide plate 200 is increased; the two ejection components work synchronously to ensure the reliability of the movement of the guide plate 200.

[0121] The aforementioned wall-mounted air conditioner indoor unit utilizes a drive motor 800 to drive a crank 900 to rotate, which in turn causes the crank 900 to drive a push rod 400 in linear motion, thereby enabling the air guide plate 200 to be pushed out and retracted. By utilizing the motion principle of the crank-push rod mechanism, not only can the stability of the push rod 400's movement be increased, but the push rod 400 can also have a larger load-bearing capacity, allowing it to drive the larger air guide plate 200. Furthermore, the push rod 400 operates with low noise and high reliability.

[0122] like Figure 2 As shown, the indoor unit of the wall-mounted air conditioner includes a rotary motor 500. The rotary motor 500 is installed on one end of the push rod 400 located outside the housing 100. The motor shaft of the rotary motor 500 is connected to one end of the air guide plate 200 along its length. The rotary motor 500 is used to drive the air guide plate 200 to rotate.

[0123] By installing the rotary motor 500 on the telescopic end of the push rod 400, the push rod 400 can drive the rotary motor 500 and the air guide plate 200 to be pushed out or retracted simultaneously, which makes it convenient for the rotary motor 500 to drive the air guide plate 200 to rotate.

[0124] like Figure 10 As shown, a channel 402 is defined inside the push rod 400. A rotary motor 500 is located inside the channel 402. The motor shaft of the rotary motor 500 passes through one end of the channel 402 sidewall and is connected to the air guide plate 200 to drive the air guide plate 200 to rotate.

[0125] Channel 402 extends along the length of push rod 400. The motor wires of rotary motor 500 are routed through channel 402, which not only hides the motor wires of rotary motor 500, but also protects them.

[0126] Since the rotary motor 500 is mounted on the push rod 400, the rotary motor 500 also moves linearly synchronously when the push rod 400 moves. Therefore, the position of the rotary motor 500 changes. The rotary motor 500 is connected to the power supply or controller and other components through the motor wire. This causes the length of the motor wire of the rotary motor 500 to change with the movement of the push rod 400 during the movement of the push rod, so as to ensure that the rotary motor 500 is reliably connected to the power supply or controller and other components.

[0127] In the existing technology, some wall-mounted air conditioner indoor units choose to reserve a certain amount of motor wire to ensure that the length of the motor wire meets the requirements when the push rod 400 is pushed out. During the retraction or retraction movement of the push rod 400 and during the push movement, the motor wire has redundancy. If the redundancy is too large, the motor wire is prone to getting tangled with components such as the crank 900 or the drive gear 810, which will have adverse consequences.

[0128] Based on this, this application sets up a winding assembly, which synchronously winds up or releases the motor wire of the rotary motor 500 with the movement of the push rod 400, thereby changing the length of the motor wire with the movement of the push rod 400.

[0129] Specifically, such as Figure 6 and Figure 7 As shown, the winding assembly includes a wire guide gear 450, and the motor wire of the rotary motor 500 is wound around the wire guide gear 450. The wire guide gear 450 is used to wind or unwind the motor wire. The wire guide gear 450 is connected to the push rod 400 and is located in the channel 402. The outer edge of the wire guide gear 450 extends out of the channel 402.

[0130] like Figure 7As shown, the winding assembly includes a rack 740, which meshes with a wire guide gear 450 to drive the wire guide gear 450 to rotate; the rack 740 is located inside the mechanism box 700 and is set along the movement trajectory of the push rod 400.

[0131] The working principle of the wire feeding gear 450 is as follows: when the push rod 400 moves linearly, the wire feeding gear 450 moves linearly synchronously with the push rod 400, and the wire feeding gear 450 moves relative to the rack 740. The wire feeding gear 450 rotates, thereby winding or releasing the motor wire of the rotary motor 500.

[0132] like Figure 8 As shown, the side wall of the channel 402 is provided with an extension portion 403 for the outer edge of the cable routing gear 450 to extend out of the channel 402. The extension portion 403 is provided on the side wall of the channel 402 extending along the movement direction of the push rod 400. The rack 740 is located on the side of the push rod 400 where the extension portion 403 is provided. The rack 740 is provided corresponding to the extension portion 403 so that the outer edge of the cable routing gear 450 can mesh with the rack 740 after extending out of the channel 402.

[0133] When the cable gear 450 rotates one revolution, the change in the motor cable is d1, and the linear motion distance of the push rod 400 is d2. d1 and d2 satisfy the relationship: d1 = d2, so that the change in the motor cable d1 and the linear motion distance d2 of the push rod 400 change synchronously, thereby ensuring that the motor cable meets the motion distance requirements of the push rod 400, and thus ensuring the reliability and safety of the rotary motor 500.

[0134] The length of the rack 740 along the first direction is greater than or equal to the movement distance of the push rod 400 along the first direction, so that when the push rod 400 is pushed out to the limit position or retracted to the limit position, the cable guide gear 450 can still mesh with the rack 740, thereby ensuring the winding and unwinding effect of the motor cable.

[0135] If the length of the rack 740 along the first direction is less than the movement distance of the push rod 400 along the first direction, the cable guide gear 450 may not be able to mesh with the rack 740 during the movement of the push rod 400. If the cable guide gear 450 cannot mesh with the rack 740, the cable guide gear 450 will not be able to rotate synchronously with the movement of the push rod 400, thus making it impossible to wind or unwind the motor cable.

[0136] The two ends of the rack 740 are at least flush with the two ends of the movement trajectory of the push rod 400, so that when the push rod 400 is pushed out to the limit position or retracted to the limit position, the cable guide gear 450 can still mesh with the rack 740, thereby ensuring the winding and unwinding effect of the motor cable.

[0137] like Figure 11 and Figure 13As shown, the cable guide gear 450 has a winding portion 451 for winding the motor wire; the winding portion 451 has a cable routing portion 4511, which is arranged radially through the winding portion 451, and the motor wire of the rotating motor 500 passes through the cable routing portion 4511 and is wound around the winding portion 451. When the cable guide gear 450 winds up or unwinds the motor wire, at least a portion of the motor wire slides relative to the cable routing portion 4511 within the cable routing portion 4511.

[0138] The wiring section 4511 is provided to pass through one end of the winding section 451 along the axial direction of the winding section 451, so as to form an inlet and outlet of the power supply line in the wiring section 4511, so that the motor line can be provided in the wiring section 4511 from the inlet and outlet, thereby allowing the motor line to pass through the wiring section 4511 for winding or unwinding.

[0139] like Figure 11 and Figure 13 As shown, the wire-carrying gear 450 is provided with a meshing part 453, which is located at the outer edge of the winding part 451 and is used to mesh with the rack 740.

[0140] like Figure 11 As shown, the winding part 451 is connected to a cover 452. The cover 452 is located on the side of the winding part 451 where the inlet and outlet are provided. It is used to block the inlet and outlet to prevent the motor wire from detaching from the inlet and outlet of the winding part 4511 when the wire feeding gear 450 is winding or releasing the motor wire, which would prevent the motor wire from being wound or released.

[0141] like Figure 12 As shown, the cover 452 has a first protrusion 4521 on the side facing the winding part 451. The first protrusion 4521 extends radially along the cover 452. The first protrusion 4521 is located in the winding part 4511 through the inlet and outlet. It can not only position the connection position between the cover 452 and the winding part 451, but also restrict the range of movement of the motor wire in the winding part 451 along the axial direction of the winding part 451, so as to prevent the motor wire from moving arbitrarily in the winding part 451 along the axial direction of the winding part 451, which would affect the winding and unwinding effect of the motor wire.

[0142] like Figure 13 As shown, the winding portion 451 is provided with a recessed portion 4512, which is recessed in the side of the winding portion 451 facing the cover 452. The setting direction of the recessed portion 4512 intersects with the setting direction of the wiring portion 4511. The cover 452 is provided with a second protrusion 4522 on the side facing the winding portion 451. The second protrusion 4522 is located in the recessed portion 4512 to further position the connection between the cover 452 and the winding portion 451.

[0143] To facilitate the installation of the cable routing gear 450 and the rotary motor 500 within the channel 402, the push rod 400 is designed as a detachable structure. When it is necessary to install or remove the cable routing gear 450 and / or the rotary motor 500, the push rod 400 can be removed.

[0144] Specifically, the push rod 400 includes a first rod 430, the end of the first rod 430 away from the crank 900 having a mounting cavity, and the rotary motor 500 is located in the mounting cavity.

[0145] The push rod 400 includes a second rod 440, which is correspondingly provided with the first rod 430 and detachably connected to each other. The first rod 430 and the second rod 440 define a channel 402 and an extension 403.

[0146] The aforementioned wall-mounted air conditioner indoor unit has a rotary motor 500 installed at the telescopic end of a push rod 400, allowing the motor wire of the rotary motor 500 to run inside the push rod 400. A wire-running gear 450 is installed on the push rod 400, and the motor wire is wound around the wire-running gear 450. A rack 740 is installed on the movement trajectory of the push rod 400, so that the wire-running gear 450 meshes with the rack 740. When the push rod 400 moves, the wire-running gear 450 rotates with the linear movement of the push rod 400 under the action of the rack 740, thereby realizing the winding and unwinding of the motor wire. This allows the length of the motor wire to be adjusted with the movement of the push rod 400, preventing excessive motor wire redundancy that could lead to tangling, and also preventing insufficient motor wire redundancy that could prevent the rotary motor 500 from connecting to the power supply.
