Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. Background Art

[0002] Existing wall-mounted air conditioners may encounter unexpected situations during daily use, such as sudden power outages or machine failures, which may cause the air outlet to fail to close automatically. Summary of the invention

[0003] The present invention aims to solve to a certain extent the technical problem in the prior art that the air outlet cannot be closed due to emergencies such as power failure and mechanical failure.

[0004] To solve the above problems, the present invention provides an air-conditioning indoor unit, comprising an upper cover, a push rod mechanism, a base and an elastic member; an air outlet is provided on the base, and the upper cover is arranged on the base; the push rod mechanism is installed on the base, and the push rod mechanism is suitable for driving the upper cover to move in a vertical direction, and the upper cover has a first position to open the air outlet and a second position to close the air outlet; two ends of the elastic member are respectively connected to the base and the push rod mechanism, and the push rod mechanism is also suitable for pushing the elastic member to compress, and the elastic member is suitable for pushing the push rod mechanism to reset when the push rod mechanism is powered off.

[0005] Thus, the upper cover can be opened by the push rod mechanism, and can be reset by the elastic member. When the air conditioner indoor unit needs to blow air, the push rod mechanism can open the upper cover to expose the air outlet, and the air conditioner indoor unit can blow out cold air or hot air through the air outlet; when it is not in use, the elastic member can close the upper cover, so that the air outlet will not be exposed to the outside for a long time and accumulate a lot of dust; when the push rod mechanism is powered off, the elastic member can drive the upper cover to automatically reset, avoiding the phenomenon that the upper cover cannot be restored after power failure. When the air conditioner indoor unit is not needed in daily life, since the air outlet is covered by the upper cover, the appearance will not be affected by the air outlet being exposed to the outside.

[0006] Optionally, the push rod mechanism includes a driving device and a push rod, the driving device is suitable for driving the first end of the push rod to move along a first linear direction, and the second end of the push rod is hinged to the upper cover.

[0007] Thus, the movement of the first end of the push rod in the first linear direction is converted into the movement of the second end of the push rod in the vertical direction, thereby driving the movement of the upper cover in the vertical direction, thereby realizing the opening and closing movement of the upper cover. Compared with the method of directly lifting the upper cover, the inclined push rod provides a secondary buffer for the linear movement of the driving device. In addition, the second end of the push rod is hingedly connected to the upper cover, thereby realizing the movable connection between the push rod mechanism and the upper cover, thereby avoiding the large assembly error between the upper cover and the base caused by the fixed connection between the push rod mechanism and the upper cover.

[0008] Optionally, the first end of the push rod is suitable for being rotatably connected to the driving end of the driving device.

[0009] Thus, the first end of the push rod and the driving end are rotatably connected, so that the horizontal movement of the driving end is converted into the rotation of the first end of the push rod relative to the driving end.

[0010] Optionally, a groove is formed at the first end of the driving end, and the push rod includes a connecting column, which is perpendicularly arranged relative to the length direction of the push rod and the first straight line direction, and the connecting column is accommodated in the groove.

[0011] Thus, the driving end is connected to the first end of the push rod through the connecting column opened by the push rod, and the driving end of the driving device can drive the first end of the push rod to move through the connecting column, thereby lifting the upper cover upward relative to the base.

[0012] Optionally, a stopper is provided on the base, a limit block is provided on the driving end, and the stopper cooperates with the limit block.

[0013] Therefore, by arranging a stopper on the base and a limiting block on the driving end, when the elastic member drives the push rod to reset the upper cover, it can be prevented that the elastic potential energy of the elastic member is too large, thereby possibly damaging the push rod mechanism.

[0014] Optionally, it also includes a first slider structure, which is arranged at the first end of the push rod. The base includes a first guide groove structure, which is arranged along the first straight line direction, and the first slider structure is slidably connected to the first guide groove structure.

[0015] Therefore, by cooperating the first slider structure arranged at the first end of the push rod with the first guide groove structure located at the base, the linear motion of the first slider structure along the first guide groove structure can be converted into vertical upward motion or vertical downward motion of the upper cover.

[0016] Optionally, the first sliding block structure is a pulley, the pulley is rotatably connected to the push rod, and the pulley is coaxial with the connecting column.

[0017] Thus, the friction between the first slider structure and the first guide groove structure can be reduced by the pulley, so that the first slider structure moves more smoothly in the first guide groove structure, thereby reducing the possibility that the upper cover cannot be opened due to excessive friction.

[0018] Optionally, the elastic member is partially accommodated in the first guide groove structure, and one end of the elastic member accommodated in the first guide groove structure is connected to the first sliding block structure.

[0019] Therefore, by partially accommodating the elastic member in the first guide groove structure, the first guide groove structure can guide the direction in which the elastic member pops out of the first slider structure, and the first guide groove structure can guide the elastic member and the first slider structure at the same time.

[0020] Optionally, a guide block is further included, wherein the guide block is installed in the first guide groove structure, one end of the guide block is in contact with the first sliding block structure, and the other end of the guide block is connected to the elastic member.

[0021] Therefore, by providing the guide block, the elastic member can be ejected along the preset position, thereby reducing the possibility that the elastic member may slide outward relative to the first slider structure when there is no guide block, resulting in the inability to push the first slider structure back to its original position.

[0022] Optionally, the first straight line direction is a left-right direction or a front-back direction.

[0023] Thus, the movement of the first end of the push rod along the first straight line direction is converted into a vertical upward lifting movement of the upper cover relative to the base.

[0024] Optionally, the push rod mechanism includes two sets, and the two sets of push rod mechanisms are symmetrically arranged along the left-right direction or the front-back direction.

[0025] Therefore, the two symmetrically arranged push rod mechanisms can lift up the upper cover at both ends simultaneously, ensuring stability during lifting and smoothness when the upper cover rises relative to the base.

[0026] Optionally, the push rod mechanism further includes a connecting rod, a first end of the connecting rod is hinged to the base, and a second end of the connecting rod is slidably connected to the upper cover.

[0027] Therefore, by setting the connecting rod, the second end of the connecting rod can support the area of ​​the upper cover away from the second end of the jacking rod during the lifting process of the upper cover, thereby preventing the upper cover from tilting to one side when the upper cover is lifted due to excessive force on one side of the upper cover.

[0028] Optionally, the connecting rod and the push rod are arranged crosswise, and the connecting rod and the push rod are hingedly connected at the intersection of the connecting rod and the push rod.

[0029] Therefore, the upper cover can be smoothly lifted up by the cross-arranged top rods and connecting rods, and the cross-arranged top rods and connecting rods can rotate relative to each other through the hinges. When the push rod mechanism lifts the upper cover, the top rods and connecting rods can be evenly stressed, reducing the impact of uneven force on the stability of the top rods and connecting rods when lifting the upper cover.

[0030] Optionally, the intersection is located in the middle of the length direction of the push rod.

[0031] Therefore, by locating the intersection at the middle position in the length direction of the push rod, the upper cover can be made more stable during the rising process, and the problem of the upper cover rising too fast or too slow will not occur. The rising speed of the upper cover can be directly adjusted by adjusting the speed of the driving push rod of the driving device.

[0032] Optionally, the connecting rod includes a second slider structure, the second slider structure is arranged at the second end of the connecting rod, the upper cover includes a second guide groove structure, and the second slider structure is slidably connected to the second guide groove structure.

[0033] Therefore, by cooperating the second slider structure arranged at the second end of the connecting rod with the second guide groove structure located on the upper cover, the linear motion of the second slider structure along the second guide groove structure can be converted into vertical upward motion or vertical downward motion of the upper cover.

[0034] Optionally, a slide groove is provided on the base, a slide rail is provided on the upper cover, and the slide groove is slidably connected to the slide rail.

[0035] Thus, the upper cover can move vertically up and down relative to the base through the slide groove and the slide rail. When the push rod mechanism drives the upper cover to lift, the upper cover can move vertically relative to the base without deviating from the vertical direction.

[0036] Optionally, there are multiple air outlets, and the multiple air outlets are respectively located on the left side wall, the right side wall and the front side wall of the base.

[0037] Thus, a plurality of air outlets can be blocked at the same time by the upper cover, and a plurality of air outlets can be opened at the same time by the upper cover, and the opening and closing of a plurality of air outlets can be controlled simultaneously by one upper cover.

[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Moreover, the Z-axis in the drawings represents the vertical direction, that is, the up and down position, and the positive direction of the Z-axis (that is, the direction of the arrow of the Z-axis) represents the top, and the negative direction of the Z-axis (that is, the direction opposite to the positive direction of the Z-axis) represents the bottom; the X-axis in the drawings represents the horizontal direction and is designated as the left and right positions, and the positive direction of the X-axis (that is, the direction of the arrow of the X-axis) represents the right side, and the negative direction of the X-axis (that is, the direction opposite to the positive direction of the X-axis) represents the left side; the Y-axis in the drawings represents the front and back positions, and the positive direction of the Y-axis (that is, the direction of the arrow of the Y-axis) represents the rear side, and the negative direction of the Y-axis (that is, the direction opposite to the positive direction of the Y-axis) represents the front side; it should be noted that the aforementioned Z-axis, Y-axis and X-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0060] The terms "first" and "second" etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0061] like Figure 1 and Figure 2As shown, the present embodiment provides an air-conditioning indoor unit 1, comprising an upper cover 2, a push rod mechanism 3, a base 4 and an elastic member 5; an air outlet 43 is provided on the base 4, and the upper cover 2 is covered on the base 4; the push rod mechanism 3 is installed on the base 4, and the push rod mechanism 3 is suitable for driving the upper cover 2 to move in a vertical direction, and the upper cover 2 has a first position to open the air outlet 43 and a second position to close the air outlet 43; two ends of the elastic member 5 are respectively connected to the base 4 and the push rod mechanism 3, and the push rod mechanism 3 is also suitable for pushing the elastic member 5 to compress, and the elastic member 5 is suitable for pushing the push rod mechanism 3 to reset when the push rod mechanism 3 is powered off.

[0062] It should be noted that when the air-conditioning indoor unit 1 needs to operate, the driving device 31 of the push rod mechanism 3 can drive the top rod 32 to move, thereby lifting the upper cover 2 relative to the base 4. At this time, the air outlet 43 located on the base 4 is exposed to the outside, and the air-conditioning indoor unit 1 can blow out cold air or hot air through the air outlet 43. The push rod 32 is located between the upper cover 2 and the base 4. The second end of the push rod 32 is hinged to the upper cover 2. The push rod 32 can rotate relative to the upper cover 2. The first end of the push rod 32 is connected to the driving device 31. When the driving device 31 is in operation, the driving device 31 can drive the first end of the push rod 32 to move along the positive direction of the X-axis, and the coordinates of the first end of the push rod 32 on the Y-axis and the Z-axis remain unchanged. Since the length of the push rod 32 does not change when the upper cover 2 is lifted, when the first end of the push rod 32 moves along the positive direction of the X-axis, the second end of the push rod 32 hinged to the upper cover 2 can rotate relative to the upper cover 2. At the same time, the second end of the push rod 32 will move along the positive direction of the Z-axis, and the coordinates of the X-axis and the Y-axis remain unchanged, thereby completing the movement of opening the upper cover 2 and opening the air outlet 43. When the upper cover 2 needs to be closed, the driving device 31 can drive the first end of the push rod 32 to move along the negative direction of the X-axis, and the coordinates of the first end of the push rod 32 on the Y-axis and the Z-axis remain unchanged. Since the length of the push rod 32 will not change when the push rod 32 is lifted or lowered, when the first end of the push rod 32 moves along the negative direction of the X-axis, the second end of the push rod 32 hinged to the upper cover 2 can rotate relative to the upper cover 2. At the same time, the second end of the push rod 32 will move along the negative direction of the Z-axis, and the coordinates of the X-axis and Y-axis remain unchanged, thereby completing the movement of closing the upper cover 2 and closing the air outlet 43.

[0063] The elastic member 5 can be located between the upper cover 2 and the base 4. When the first end of the push rod 32 moves along the positive direction of the X axis, the second end of the push rod 32 moves along the positive direction of the Y axis. At this time, the elastic member 5 is stretched because the upper cover 2 moves upward relative to the base 4. The elastic member 5 can be a spring. The spring has elastic potential energy due to being stretched. When the upper cover 2 needs to be reset, the elastic member 5 returns to its original state and pulls the upper cover 2 to cover the base 4, so that the air outlet 43 can be covered. The elastic member 5 can also be connected to the push rod mechanism 3 and the base 4 respectively. When the push rod mechanism 3 is in operation, the push rod mechanism 3 can push the elastic member 5, and the elastic member 5 is compressed by the push rod mechanism 3. The compressed elastic member 5 has elastic potential energy. The elastic member 5 can be a spring. When the push rod mechanism 3 is powered off, the elastic member 5 can drive the upper cover 2 to automatically reset. When the air conditioner indoor unit 1 is not needed in daily life, since the air outlet 43 is covered by the upper cover 2, the appearance will not be affected by the air outlet 43 being exposed to the outside.

[0064] The advantage of such a configuration is that the upper cover 2 can be opened by the push rod mechanism 3, and the upper cover 2 can be reset by the elastic member 5. When the air conditioner indoor unit 1 needs to discharge air, the push rod mechanism 3 can open the upper cover 2 to expose the air outlet 43, and the air conditioner indoor unit 1 can blow out cold air or hot air through the air outlet 43; when it is not in use, the elastic member 5 can close the upper cover 2, so that the air outlet 43 will not be exposed to the outside for a long time and accumulate a lot of dust; when the push rod mechanism 3 is powered off, the elastic member 5 can drive the upper cover 2 to automatically reset, avoiding the phenomenon that the upper cover 2 cannot be restored after power failure. When the air conditioner indoor unit 1 is not needed in daily life, since the air outlet 43 is covered by the upper cover 2, the appearance will not be affected by the air outlet 43 being exposed to the outside.

[0065] like Figure 3 and Figure 4 As shown, the push rod mechanism 3 includes a driving device 31 and a push rod 32 . The driving device 31 is suitable for driving the first end of the push rod 32 to move along a first linear direction, and the second end of the push rod 32 is hinged to the upper cover 2 .

[0066] It should be noted that when the push rod mechanism 3 pushes the upper cover 2 upward relative to the base 4, the second end of the push rod 32 hinged to the upper cover 2 can rotate counterclockwise relative to the upper cover 2, and the first end of the push rod 32 can slide relative to the base 4 in the positive direction of the X-axis. The base 4 can be provided with a sliding groove for the first end of the push rod 32 to slide. During the lifting process of the push rod 32, the first end of the push rod 32 slides in the sliding groove, thereby completing the action of lifting the upper cover 2 relative to the base 4. When the push rod mechanism 3 pushes the upper cover 2 downward relative to the base 4 to close, the second end of the push rod 32 hinged to the upper cover 2 can rotate clockwise relative to the upper cover 2, and the first end of the push rod 32 can slide relative to the base 4 in the negative direction of the X-axis. The base 4 can be provided with a sliding groove for the first end of the push rod 32 to slide. During the process of the push rod 32 closing the upper cover 2, the first end of the push rod 32 slides in the sliding groove, thereby completing the action of closing the upper cover 2 relative to the base 4.

[0067] The advantage of such a configuration is that the movement of the first end of the push rod 32 in the first linear direction is converted into the movement of the second end of the push rod 32 in the vertical direction, thereby driving the movement of the upper cover 2 in the vertical direction, thereby realizing the opening and closing movement of the upper cover 2. Compared with the method of directly lifting the upper cover 2, the tilted push rod 32 performs secondary buffering on the linear movement of the driving device 31. In addition, the second end of the push rod 32 is hingedly connected to the upper cover 2, thereby realizing the movable connection between the push rod mechanism 3 and the upper cover 2, thereby avoiding the large assembly error between the upper cover and the base 4 caused by the fixed connection between the push rod mechanism 3 and the upper cover 2.

[0068] like Figures 4 to 7 As shown, the first end of the push rod 32 is suitable for being rotatably connected to the driving end 311 of the driving device 31 .

[0069] One end of the driving end 311 that is rotatably connected to the top rod 32 may be provided with an opening, and a rotating shaft may be provided on the first end of the top rod 32, the rotating shaft is passed through the opening, and the rotating shaft can rotate relative to the opening, and the rotating shaft is fixedly connected to the top rod 32. When the rotating shaft rotates relative to the opening, the top rod 32 will also rotate relative to the driving end 311, and the driving end can move along the X-axis direction, thereby driving the first end of the top rod 32 to move along the X-axis direction. Therefore, by the first end of the top rod 32 and the driving end 311 being rotatably connected, the horizontal movement of the driving end 311 is converted into the rotation of the first end of the top rod 32 relative to the driving end 311.

[0070] like Figures 4 to 7 As shown, a groove 3111 is formed at the first end of the driving end 311 , and the push rod 32 includes a connecting column 321 , which is perpendicularly arranged relative to the length direction of the push rod 32 and the first straight line direction, and is accommodated in the groove 3111 .

[0071] The connecting column 321 can be inserted into the groove 3111 of the driving end 311. When the driving end 311 of the driving device 31 moves along the positive direction of the X-axis, the connecting column 321 can rotate relative to the groove 3111, thereby driving the first end of the push rod 32 to rotate relative to the driving end 311. The push rod 32 and the Y-axis direction can have a certain angle. When the first end of the push rod 32 rotates, the first end of the push rod 32 is driven by the driving end 311 to move along the X-axis in a square. The angle between the push rod 32 and the Y-axis direction gradually decreases, so that the upper cover 2 can be lifted upward. Therefore, the driving end 311 is connected to the first end of the push rod 32 through the connecting column 321 provided on the push rod 32. The driving end 311 of the driving device 31 can drive the first end of the push rod 32 to move through the connecting column 321, thereby lifting the upper cover 2 upward relative to the base 4.

[0072] like Figure 8 As shown, a stopper 44 is provided on the base 4, and a limit block 3112 is provided on the driving end 311, and the stopper 44 cooperates with the limit block 3112 in a stop manner.

[0073] It should be noted that the stopper 44 can be located on the path of the driving end 311 when it moves. The driving device 31 can also include a driving device body 312. The driving device body 312 can drive the driving end 311 to push out or retract. The limit block 3112 is located on the driving end 311. When the driving device 31 is suddenly powered off, the driving end 311 moves toward one end close to the driving device 31 due to the elastic force of the elastic member 5. At this time, the elastic potential energy stored in the elastic member 5 is too large, which may cause damage to the push rod mechanism 3. At this time, A stopper 44 is provided between the driving end 311 and the driving device body 312, and a limit block 3112 cooperating with the stopper 44 is provided on the driving end 311. When the driving end 311 is retracted into the driving device body 312 due to the elastic force of the elastic member 5, the driving end 311 can be stopped by the stopper cooperation of the limit block 3112 and the stopper 44, so as to prevent the driving end 311 from being ejected excessively due to excessive elastic potential energy stored in the elastic member 5, which may damage the connection between the driving end 311 and the top rod 32.

[0074] The advantage of such a configuration is that, by providing a stopper 44 on the base 4 and a limiting block 3112 on the driving end 311, when the elastic member 5 drives the push rod 32 to reset the upper cover 2, it is possible to prevent the elastic potential energy of the elastic member 5 from being too large, thereby preventing the push rod mechanism 3 from being damaged.

[0075] like Figures 8 to 14As shown, it also includes a first slider structure 322, which is arranged at the first end of the top rod 32, and the base 4 includes a first guide groove structure 41, which is arranged along the first straight line direction, and the first slider structure 322 is slidably connected to the first guide groove structure 41.

[0076] It should be noted that the first guide groove structure 41 can be arranged on the inner surface of the upper cover 2, and the first guide groove structure 41 can be arranged along the length direction of the upper cover 2. The first slider structure 322 can be accommodated in the first guide groove structure 41, and the first slider structure 322 is used to drive the first end of the push rod 32 to slide in the first guide groove structure 41. The first slider structure 322 can include a first slider structure body 3221 and a first protrusion structure 3222. The first protrusion structure 3222 is accommodated in the first guide groove structure 41. The cross-sectional area of ​​the first protrusion structure 3222 can be greater than the cross-sectional area of ​​the first slider structure body 3221. The first protrusion structure 3222 fits the first guide groove structure 41. The first protrusion structure 3222 can prevent the first slider structure 322 from falling off from the first guide groove structure 41. When the first slider structure 322 slides in the first guide groove structure 41, the upper cover 2 can be opened or closed relative to the base 4.

[0077] The advantage of such a configuration is that, by cooperating with the first guide groove structure 41 located at the base 4 through the first slider structure 322 disposed at the first end of the top rod 32, the linear motion of the first slider structure 322 along the first guide groove structure 41 can be converted into vertical upward motion or vertical downward motion of the upper cover 2.

[0078] like Figures 8 to 14 As shown, the first slider structure 322 is a pulley, the first slider structure 322 is a pulley, the pulley is rotatably connected to the top rod 32, and the pulley is coaxial with the connecting column 321.

[0079] The pulley can be accommodated in the first guide groove structure 41, and the pulley can roll in the first guide groove structure 41. Therefore, the friction between the first slider structure 322 and the first guide groove structure 41 can be reduced by the pulley, so that the first slider structure 322 moves more smoothly in the first guide groove structure 41, and the situation that the upper cover 2 cannot be opened due to excessive friction is reduced.

[0080] like Figures 8 to 14 As shown, the elastic member 5 is partially accommodated in the first guide slot structure 41 , and one end of the elastic member 5 accommodated in the first guide slot structure 41 is connected to the first sliding block structure 322 .

[0081] It should be noted that one end of the elastic member 5 can be fixed on the base 4, and the other end of the elastic member 5 can be partially inserted into the first guide groove structure 41 and contact with the first slider structure 322. When the first slider slides in the first guide structure in the direction of compressing the elastic member 5, the elastic member 5 can store elastic potential energy after being compressed. After the elastic member 5 is fully compressed, the end of the elastic member 5 that contacts the first slider structure 322 can be in the first guide groove structure 41. When the driving device 31 is powered off, the elastic potential energy stored in the elastic member 5 can push the first slider structure 322 out in the stretching direction of the elastic member 5. The first guide groove structure 41 can guide the elastic member 5, so that the first slider structure 322 can pop out along the first guide groove structure 41.

[0082] The advantage of this arrangement is that by partially accommodating the elastic member 5 in the first guide groove structure 41, the first guide groove structure 41 can guide the elastic member 5 in the direction of popping out of the first slider structure 322, and the first guide groove structure 41 can guide the elastic member 5 and the first slider structure 322 at the same time.

[0083] like Figures 8 to 14 As shown, it also includes a guide block 323, which is installed in the first guide groove structure 41, one end of the guide block 323 is in contact with the first slider structure 322, and the other end of the guide block 323 is connected to the elastic member 5.

[0084] It should be noted that one end of the guide block 323 may contact the first slider structure 322, and the other end of the guide block 323 may be connected to the elastic member 5. The elastic member 5 may be a spring. When there is no guide block 323, one end of the spring may directly contact the first slider structure 322. At this time, since the spring and the first slider structure 322 are not directly fixed, the spring and the first guide groove structure 41 may not be completely matched. At this time, the spring may release the elastic potential energy after being compressed, and the end of the spring in contact with the first slider structure 322 may slip due to excessive elastic potential energy. The spring may pop out from the side of the first guide groove structure 41 with an opening, and the first slider structure 322 cannot be pushed back to the preset position, and there is no way to complete the reset of the upper cover 2. At this time, by setting the guide block 323, one end of the spring can be fixed to the guide block 323, and the other end of the spring can be fixed to the base 4, the guide block 323 can slide in the first guide groove structure 41, and the first guide groove structure 41 can limit the movement direction of the guide block 323, so that the guide block 323 can only move along the direction of the first guide groove structure 41.

[0085] The advantage of such a configuration is that, by providing the guide block 323, the elastic member 5 can be popped out along a preset position, thereby reducing the possibility that the elastic member 5 may slide outward relative to the first slider structure 322 when there is no guide block 323, thereby preventing the first slider structure 322 from being pushed back to its original position.

[0086] The first straight line direction is the left-right direction or the front-back direction.

[0087] The driving device 31 can be arranged along the X-axis direction of the base 4, and the driving device 31 can also be arranged along the Y-axis direction of the base 4. When the driving device 31 drives the first end of the push rod 32 to move along the first linear direction, the first end of the push rod 32 can move linearly along the X-axis direction, and the first end of the push rod 32 can also move linearly along the Y-axis direction. The movement direction of the first end of the push rod 32 is consistent with the setting direction of the driving device 31 along the X-axis or Y-axis. Therefore, the movement of the first end of the push rod 32 along the first linear direction is converted into a vertical upward lifting movement of the upper cover 2 relative to the base 4.

[0088] like Figure 1 As shown, the push rod mechanism 3 includes two sets, and the two sets of push rod mechanisms 3 are arranged along the front-to-back direction or the left-to-right direction of the base 4.

[0089] The two push rod mechanisms 3 can be symmetrically arranged, and the two push rod mechanisms 3 can be arranged along the X-axis direction of the base 4 and located at both ends of the base 4; the two push rod mechanisms 3 can also be arranged along the Y-axis direction of the base 4 and located at both ends of the base 4. Thus, the two symmetrically arranged push rod mechanisms 3 can lift the upper cover 2 at both ends at the same time, ensuring the stability of the lifting and the smoothness of the upper cover 2 when it rises relative to the base 4.

[0090] like Figure 8 As shown, the push rod mechanism 3 also includes a connecting rod, and the push rod mechanism 3 also includes a connecting rod 33. The first end of the connecting rod 33 is hinged to the base 4, and the second end of the connecting rod 33 is slidably connected to the upper cover 2.

[0091] It should be noted that when the push rod mechanism 3 pushes the upper cover 2 upward relative to the base 4, the first end of the connecting rod 33 hinged with the base 4 can rotate clockwise relative to the base 4, and the second end of the connecting rod 33 can slide relative to the upper cover 2 in a direction close to the second end of the top rod 32. The upper cover 2 can be provided with a sliding groove for the second end of the connecting rod 33 to slide. During the lifting process of the connecting rod 33, the second end of the connecting rod 33 slides in the sliding groove, thereby completing the action of lifting the upper cover 2 relative to the base 4. When the push rod mechanism 3 pushes the upper cover 2 downward relative to the base 4 to close, the first end of the connecting rod 33 hinged with the base 4 can rotate counterclockwise relative to the base 4, and the second end of the connecting rod 33 can slide relative to the upper cover 2 in a direction away from the second end of the top rod 32. The upper cover 2 can be provided with a sliding groove for the second end of the connecting rod 33 to slide. During the process of the connecting rod 33 closing the upper cover 2, the second end of the connecting rod 33 slides in the sliding groove, thereby completing the action of closing the upper cover 2 relative to the base 4.

[0092] The advantage of such a configuration is that, by providing the connecting rod 33, during the lifting process of the upper cover 2, the second end of the connecting rod 33 can support the area of ​​the upper cover 2 away from the second end of the top rod 32, thereby preventing the upper cover 2 from tilting to one side when the upper cover 2 is lifted due to excessive force on one side of the upper cover 2.

[0093] like Figure 8 As shown, the connecting rod 33 and the push rod 32 are arranged crosswise, and the connecting rod 33 and the push rod 32 are hingedly connected at the intersection of the connecting rod 33 and the push rod 32.

[0094] It should be noted that the hinge between the connecting rod 33 and the top rod 32 can be located at the center of the top rod 32 and biased towards the first end of the top rod 32, and the distance from the hinge to the first end of the top rod 32 and the distance to the first end of the connecting rod 33 can be equal. When the driving device 31 drives the first end of the push rod 32, the distance moved in the horizontal direction by the first end of the push rod 32 can be smaller than the distance moved in the horizontal direction by the second end of the push rod 32. In the process of the push rod 32 lifting the upper cover 2, the push rod 32 can be regarded as a laborious lever. According to the formula of the lever principle: power × power arm = resistance × resistance arm, it can be seen that the power arm of the laborious lever is smaller than the length of the resistance arm, then the corresponding power must be greater than the resistance, that is, the force of the driving end 311 of the driving device 31 is greater than the resistance of lifting the upper cover 2. The laborious lever can achieve the effect of saving effort and distance, that is, the distance moved by the first end of the push rod 32 is smaller than the distance moved by the second end of the push rod 32, so that the upper cover 2 can be opened faster; of course, the hinge between the connecting rod 33 and the push rod 32 can be located at the center of the push rod 32, biased towards the second end of the push rod 32, and the distance from the hinge to the second end of the push rod 32 and the distance to the second end of the connecting rod 33 can be equal. When the driving device 31 drives the first end of the push rod 32, the distance that the first end of the push rod 32 moves in the horizontal direction can be greater than the distance that the second end of the push rod 32 moves in the horizontal direction. In the process of the push rod 32 lifting the upper cover 2, the push rod 32 can be regarded as a labor-saving lever. According to the formula of the lever principle: power × power arm = resistance × resistance arm, it can be known that the power arm of the labor-saving lever is greater than the length of the resistance arm, so the corresponding power must be less than the resistance, that is, the force of the driving end 311 of the driving device 31 is less than the resistance of lifting the upper cover 2. The labor-saving lever can achieve the effect of saving effort and distance, that is, the distance that the first end of the push rod 32 moves is greater than the distance that the second end of the push rod 32 moves, which can reduce the force when the driving device 31 drives the first end of the push rod 32. Similarly, the connecting rod 33 has the same effect as the above-mentioned push rod 32 in this embodiment, which will not be repeated here.

[0095] The advantage of such an arrangement is that the upper cover 2 can be smoothly lifted upward by means of the cross-arranged top rods 32 and connecting rods 33, and the cross-arranged top rods 32 and connecting rods 33 can rotate relative to each other through the hinges. When the push rod mechanism 3 lifts the upper cover 2, the top rods 32 and connecting rods 33 can be evenly stressed, thereby reducing the impact of uneven stress on the stability of the top rods 32 and connecting rods 33 when lifting the upper cover 2.

[0096] like Figure 8 As shown, the intersection is located in the middle of the length direction of the top rod 32.

[0097] It should be noted that the lengths of the connecting rod 33 and the push rod 32 can be the same, the distances from the intersection of the connecting rod 33 and the push rod 32 to the two ends of the connecting rod 33 can be equal, and the distances from the intersection of the connecting rod 33 and the push rod 32 to the two ends of the push rod 32 can also be equal. When the first end of the push rod 32 moves on the X-axis, the second end of the connecting rod 33 can move the same distance as the first end of the push rod 32 on the X-axis, and the upper cover 2 can move upward smoothly. The intersection is located at the center of the push rod 32, and the push rod 32 can be regarded as an equal-arm lever. According to the formula of the lever principle: power × power arm = resistance × resistance arm, it can be seen that the power arm and resistance arm of the equal-arm lever are equal, so the power and resistance acting on the two ends of the power arm and the resistance arm are also equal. Similarly, the connecting rod 33 has the same effect as the above-mentioned push rod 32 in this embodiment, which will not be repeated here.

[0098] like Figure 8 and Fig.15 As shown, the connecting rod 33 includes a second slider structure 331, which is arranged at the second end of the connecting rod 33, and the upper cover 2 includes a second guide groove structure 21, which is arranged along the first straight line direction, and the second slider structure 331 is slidably connected to the second guide groove structure 21.

[0099] It should be noted that the second guide groove structure 21 can be arranged on the inner surface of the upper cover 2, and the second guide groove structure 21 can be arranged along the length direction of the upper cover 2. The second slider structure 331 can be accommodated in the second guide groove structure 21, and the second slider structure 331 is used to drive the second end of the connecting rod 33 to slide in the second guide groove structure 21. The second slider structure 331 can include a second slider structure body 3311 and a second protrusion structure 3312, and the second protrusion structure 3312 is accommodated in the second guide groove structure 21. The cross-sectional area of ​​the second protrusion structure 3312 can be larger than the cross-sectional area of ​​the second slider structure body 3311. The second protrusion structure 3312 fits with the second guide groove structure 21, and the second protrusion structure 3312 can prevent the second slider structure 331 from falling off from the second guide groove structure 21. When the second slider structure 331 slides in the second guide groove structure 21, the upper cover 2 can be opened or closed relative to the base 4.

[0100] The advantage of this arrangement is that, by cooperating with the second guide groove structure 21 located on the upper cover 2, the linear motion of the second slider structure 331 along the second guide groove structure 21 can be converted into vertical upward motion or vertical downward motion of the upper cover 2.

[0101] like Fig.16 and Fig.17 As shown, a slide groove 42 is provided on the base 4 , a slide rail 22 is provided on the upper cover 2 , and the slide groove 42 is slidably connected to the slide rail 22 .

[0102] The slide groove 42 can be located on the side wall of the base 4, and the slide rail 22 of the upper cover 2 can slide in the slide groove 42 of the side wall. The movement direction of the upper cover 2 can be guided by the slide groove 42, so that the upper cover 2 can slide along the direction of the slide groove 42 of the base 4. Therefore, the upper cover 2 can move vertically up and down relative to the base 4 through the slide groove 42 and the slide rail 22. When the push rod mechanism 3 drives the upper cover 2 to lift, the upper cover 2 can move vertically relative to the base 4 without deviating from the vertical direction.

[0103] like Figure 1 and Figure 2 As shown, there are multiple air outlets 43 , and the multiple air outlets 43 are respectively located on the left side wall, the right side wall and the front side wall of the base 4 .

[0104] The upper cover 2 is disposed on the base 4, and the side wall of the upper cover 2 can block the side wall of the base 4, and the air outlets 43 are located on the left side wall, the right side wall and the front side wall of the base 4. When the air conditioner indoor unit 1 is not required to operate, the push rod mechanism 3 can cover multiple air outlets 43 at the same time by driving the upper cover 2 to close, so as to prevent dust from entering; when the air conditioner indoor unit 1 is in operation, the push rod mechanism 3 can expose multiple air outlets 43 by driving the upper cover 2 to open, and the air outlets 43 can be used to discharge cold air or hot air into the room. Thus, multiple air outlets 43 can be blocked at the same time by the upper cover 2, and multiple air outlets 43 can also be opened at the same time by the upper cover 2, and the opening and closing of multiple air outlets 43 can be controlled simultaneously by one upper cover 2.

[0105] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
