Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide plate control mechanism for an air conditioning unit, and a method for adjusting a worn push rod. Background Art

[0002] Air deflectors are installed at the air outlet of the indoor unit of the air conditioner. Generally, the air deflectors are plate-shaped injection molded parts, and their movement can be controlled by a gear rack transmission mechanism or a hinge rod transmission mechanism.

[0003] For example, in some air-conditioning products, a gear rack transmission mechanism is used to control the sliding movement of the air guide plate. In this case, the air guide plate is generally fixed to the rack, and the rack can be arc-shaped or straight-line. If the rack is arc-shaped, the air guide plate is controlled to slide along an arc-shaped trajectory so that the air guide plate cooperates with the air outlet opened at the arc-shaped shell; if the rack is straight-line, the air guide plate is controlled to slide along a straight-line trajectory so that the air guide plate cooperates with the air outlet opened at the flat shell. When the gear drives the rack to move forward, the air guide plate gradually moves to the position of the air outlet of the air conditioner indoor unit, thereby keeping the air outlet closed and preventing external dust / flying insects / debris from contaminating the interior of the air conditioner; when the gear drives the rack to move backward, the air guide plate is controlled to leave the position of the air outlet and retract to a position that coincides with the air conditioner shell, so that the air outlet is in an open state, realizing air outlet of the air conditioner.

[0004] For example, in some air conditioners, a hinged rod transmission mechanism controls the flipping of the air deflector. The upper inner portion of the air deflector is hinged to a central axis of rotation, while the lower portion is hinged to the control end of the hinged rod transmission mechanism. The drive end of the hinged rod transmission mechanism is connected to a motor. When the motor drives the hinged rod transmission mechanism, the air deflector is controlled to flip around the central axis of rotation. Forward flipping opens the air outlet, while reverse flipping closes the air outlet. During this process, the air outlet direction of the indoor unit of the air conditioner can be adjusted by adjusting the flip angle of the air deflector. The flip angle of the air deflector generally does not exceed 90°.

[0005] In these air conditioners, the air deflector is typically located within the air outlet. To prevent the air deflector from colliding with the air conditioner housing when moving or flipping, a large gap must be left between the air deflector and the air outlet frame. This gap inevitably prevents the air outlet from being fully closed, resulting in poor shielding against pollution sources such as dust, flying insects, and debris.

[0006] Therefore, how to improve the sealing of the air outlet of the air conditioner indoor unit when it is closed, and how to adjust the air outlet direction of the air conditioner indoor unit to a larger angle are technical problems that need to be urgently solved by technical personnel in this field. Summary of the Invention

[0007] In view of this, the present invention aims to provide an air deflector control mechanism for an air conditioner, and a method for adjusting a worn push rod. This air deflector control mechanism can improve the sealing of the air outlet of an air conditioner indoor unit when closed, and can also adjust the air outlet direction of the indoor unit to a wider angle. This method can also help extend the service life of the air conditioner.

[0012] The first driver is used to control the air guide plate to flip to a preset air guide position.

[0013] When the air conditioner air guide plate control mechanism is working, the linear transmission mechanism is used to control the air guide plate to move away from the air outlet to a preset extended position, and then the first driver is used to control the air guide plate to rotate around the axis to the preset air guide position according to the air outlet direction.

[0017] A first push rod and a second push rod are provided on the side wall of the force rod shaft. The first push rod and the second push rod are respectively fixedly connected to the force rod shaft perpendicularly and at an obtuse angle. The length of the first push rod and the second push rod are both L2. The diameter of the force rod shaft is L3, and L2+L3<L1<L2+L3+L2;

[0018] The second driver is used to control the force rod shaft to rotate around the central axis of the force rod shaft by a preset angle;

[0019] One end of the second component extends out of the air outlet and is connected to the air guide plate;

[0020] If the first component is fixedly connected to the air conditioner body, the second driver and the force rod shaft are both mounted on the second component, and the second component and the air conditioner body are slidably connected via a linear guide groove;

[0021] If the second driver and the force rod shaft are both mounted on the air conditioner body, the first component is fixedly connected to the second component, and the first component or the second component is slidably connected to the air conditioner body via a linear guide groove.

[0022] Optionally, the above-mentioned air-conditioning air guide plate control mechanism further includes a mechanism box, and the force rod shaft, the second driver, the first working surface, and the second working surface are all located in the mechanism box.

[0023] Optionally, in the above-mentioned air-conditioning air guide plate control mechanism, a third push rod is also provided on the side wall of the force rod shaft. The length of the third push rod is L2, and it is vertically fixed to the force rod shaft. The first push rod, the second push rod, and the third push rod are evenly distributed around the central axis of the force rod shaft.

[0024] Optionally, in the above-mentioned air-conditioning air guide plate control mechanism, the first push rod, the second push rod, and the third push rod are arranged at intervals along the axial direction of the force rod shaft.

[0025] Optionally, in the above-mentioned air-conditioning air guide plate control mechanism, the first working surface and the second working surface are both provided with wear detectors for detecting the degree of wear of the first push rod, the second push rod, and the third push rod respectively.

[0026] A method for adjusting a worn push rod of the above-mentioned air guide plate control mechanism of an air conditioner, the method comprising the following steps:

[0027] Step S1: the first push rod and the second push rod are in use, for controlling the translation of the first component, and the third push rod is in an idle state;

[0028] Step S2: When the wear of the first push rod is greater than 0.5 mm, the first push rod is adjusted to enter an idle state and the third push rod is put into use state, so as to control the translation of the first component through the third push rod and the second push rod.

[0029] Optionally, the above-mentioned worn push rod adjustment method also includes step S301: when the wear of the third push rod is greater than 0.5 mm, the third push rod is adjusted to enter an idle state, and the first push rod enters a use state, so as to control the translation of the first component through the first push rod and the second push rod.

[0031] Optionally, the above-mentioned worn push rod adjustment method also includes step S4: when the wear of two push rods among the first push rod, the second push rod, and the third push rod is greater than 0.5 mm, the wear degree of the three push rods is compared, and the two push rods with the smallest wear are selected to control the translation of the first component, and the push rod with the largest wear is in an idle state.

[0032] As can be seen from the above technical solution, in the air conditioner air deflector control mechanism provided by the present invention, since the air deflector is tilted to adjust the air outlet angle after it is away from the air outlet, the size of the air deflector and its tilting action are not restricted by the air outlet, resulting in a wider adjustable range of the air outlet angle. Furthermore, the air deflector can be configured as a plate-shaped structure larger than the air outlet to ensure a tight seal when the air outlet is closed.

[0041] The present invention discloses an air deflector control mechanism for an air conditioner and a method for adjusting a wear push rod. The air deflector control mechanism can improve the sealing performance of the air outlet of an air conditioner indoor unit when closed, and can also adjust the air outlet direction of the indoor unit to a wider angle. The wear push rod adjustment method can also help extend the service life of the air conditioner.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] First specific embodiment

[0044] A first specific embodiment of the present invention provides an air guide plate control mechanism for an air conditioner.

[0045] See also Figures 1 to 6 The air-conditioning air guide plate control mechanism provided by the first embodiment of the present invention includes an air guide plate 9, a linear transmission mechanism and a first driver 8.

[0046] The air guide plate 9 is located outside the air outlet 10 of the air conditioner body and can cover the entire area where the air outlet 10 is located, thereby ensuring the sealing of the air outlet when it is closed;

[0047] The linear transmission mechanism is used to control the air guide plate 9 to move away from the air outlet 10, and is used to control the air guide plate to move towards the air outlet 10;

[0048] The first driver 8 is used to control the air guide plate 9 to flip to a preset air guide position.

[0049] When the air conditioner air guide plate control mechanism is working, the linear transmission mechanism is used to control the air guide plate 9 to move away from the air outlet 10 to a preset extended position, and then the first driver 8 is used to control the air guide plate 9 to rotate around the axis to the preset air guide position according to the air outlet direction.

[0050] In the air conditioner air guide plate control mechanism, since the air guide plate 9 is turned over to adjust the air outlet angle after it is away from the air outlet 10, the size of the air guide plate and its turning action are not restricted by the air outlet, and the adjustable range of the air outlet angle of the air guide plate 9 is larger. For example, see Figure 1 and Figure 2 , which can make the wind deflector 9 turn clockwise to different angles; for example, see Figure 3 and Figure 4 , the air guide plate 9 can also be turned counterclockwise to different angles.

[0051] It should be noted here that, in specific implementation, the air guide plate 9 is generally a plate-like structure that is larger than the air outlet 10 , so that when the air guide plate 9 moves to fit the outer side surface of the surrounding shell of the air outlet 10 , it can completely cover the entire area where the air outlet 10 is located.

[0052] In specific implementation, the linear transmission mechanism is used to control the movement of the air deflector 9 along a linear trajectory perpendicular to the plane of the air outlet 10. The drive end of the linear transmission mechanism is connected to the drive shaft of the second driver 4, and the control end of the linear transmission mechanism is hinged to the inner side of the air deflector 9. If the linear transmission mechanism controls the air deflector 9 to move away from the air outlet 10, the air outlet 10 is in the open state. If the linear transmission mechanism controls the air deflector 9 to move toward the air outlet 10 until it abuts the outer side of the surrounding shell of the air outlet 10, the air outlet 10 is in the closed state.

[0053] Preferably, the preset extension position and the preset wind guide position have a plurality of different options, so that the wind guide plate 9 can meet the requirements of a plurality of different wind guide angles.

[0054] In a specific implementation, the first driver 8 is preferably a rotary motor located at the junction of the air deflector 9 and the linear transmission mechanism. The inner side of the air deflector 9 is connected to the linear transmission mechanism (specifically, the second member 7 hereinafter) via an axial hole structure, and the air deflector is connected to the connecting rod via an axial hole. A rotary motor (i.e., the first driver 8) is mounted at the axial hole connection. Rotation of the motor controls the air deflector 9 to flip and guide the air.

[0055] Specifically, see Figure 5 and Figure 6 The linear transmission mechanism includes a first component 2, a second component 7, a force rod shaft 5, and a second driver 4.

[0056] The first component 2 is fixedly connected to the air conditioner body. The first component 2 includes a first stopper 21 and a second stopper 22 arranged in parallel. The force rod shaft 5 is located between the first stopper 21 and the second stopper 22. The side of the first stopper 21 close to the force rod shaft 5 is a first working surface, and the side of the second stopper 22 close to the force rod shaft 5 is a second working surface. The central axis of the force rod shaft 5, the first working surface, and the second working surface are parallel to each other. The distance between the first working surface and the second working surface is L1.

[0057] The side wall of the force rod shaft 5 is provided with a first push rod 61 and a second push rod 62. The first push rod 61 and the second push rod 62 are respectively fixedly connected to the force rod shaft 5 perpendicularly, and the included angle is an obtuse angle. The length of the first push rod 61 and the second push rod 62 are both L2. The diameter of the force rod shaft 5 is L3, L2+L3<L1<L2+L3+L2;

[0058] The second driver 4 is used to control the force rod shaft 5 to rotate around the central axis of the force rod shaft 5 by a preset angle;

[0059] The second member 7 is slidably connected to the air conditioner body via a linear guide groove 1, and one end of the second member 7 extends out of the air outlet 10 and is connected to the air guide plate 9;

[0060] The second driver 4 and the force rod shaft 5 are both mounted on the second component 7 .

[0061] Thus, when the force rod shaft 5 rotates, the force rod shaft 5 , the second driver 4 , the second component 7 , and the air guide plate 9 simultaneously translate relative to the air conditioner body to control the air guide plate 9 to move away from / close to the air outlet 10 .

[0062] In specific implementation, the second driver 4 is preferably a rotary motor.

[0063] Furthermore, in the above-mentioned air-conditioning air guide plate control mechanism, a mechanism box 3 is also included. Among them, the force rod shaft 5, the second driver 4, the first working surface of the first stopper 21, and the second working surface of the second stopper 22 are all located in the mechanism box 3, and the second component 7 is fixedly connected to the mechanism box 3. Specifically, as Figure 5 and Figure 6 As shown in the figure, a part of the first stopper 21 (provided with a first working surface) is located inside the mechanism box 3, and the other part is located outside the mechanism box 3 and is fixedly connected to the air-conditioning body; a part of the second stopper 22 (provided with a second working surface) is located inside the mechanism box 3, and the other part is located outside the mechanism box 3 and is fixedly connected to the air-conditioning body.

[0064] See Figure 5 and Figure 6 , Figure 5 The force rod shaft 5 rotates clockwise in the direction of the curved arrow, and the second component 7 and the air guide plate 9 move away from the air outlet 10. The specific process is as follows:

[0065] When the second driver 4 controls the lever shaft 5 to rotate clockwise, an interaction force is generated between the first push rod 61 and the first stopper 21. At this time, the mechanism box 3, the second driver 4, the lever shaft 5, the second component 7, and the air deflector 9 will move to the left as a whole, thereby controlling the air deflector 9 to gradually move away from the air outlet 10. The lever shaft 5 rotates to a preset angle and the air deflector 9 stops when it moves to a preset position. Subsequently, the first driver 8 controls the air deflector 9 to flip to the wind-guiding position to guide the air.

[0066] When the second driver 4 controls the force rod shaft 5 to rotate counterclockwise, an interaction force is generated between the second push rod 62 and the second stopper 22. At this time, the mechanism box 3, the second driver 4, the force rod shaft 5, the second component 7, and the air guide plate 9 will move to the right as a whole, thereby controlling the air guide plate 9 to gradually approach the air outlet 10 until the wind shield plate 9 fits with the surrounding shell of the air outlet to control the air outlet to be in a closed state.

[0067] In order to further optimize the above technical solution, a third push rod 63 is further provided on the side wall of the force rod shaft 5. The length of the third push rod 63 is L2 and it is vertically fixed to the force rod shaft 5. The first push rod 61, the second push rod 62 and the third push rod 63 are evenly distributed around the central axis of the force rod shaft 5. Thus, the angle between two adjacent push rods is 120 degrees.

[0068] Specifically, the first push rod 61, the second push rod 62, and the third push rod 63 are arranged at intervals along the axial direction of the force rod shaft 5. Therefore, the three push rods slide and rub in different areas on each baffle, which is beneficial to avoid excessive wear of the baffle working surface.

[0069] Furthermore, wear detectors may be provided on the first working surface of the first stopper 21 and the second working surface of the second stopper 22 to monitor the degree of wear of the first push rod 61, the second push rod 62, and the third push rod 63. Thus, the controller can select the two push rods with the least wear to enter the use state and the push rod with the most wear to enter the idle state based on the degree of wear of the push rods, thereby extending the service life of the air guide control mechanism of the air conditioner.

[0070] Specifically, a wear detector is provided on the first working surface of the first stopper 21 for detecting the degree of wear of the first push rod 61 and the third push rod 63; a wear detector is provided on the second working surface of the second stopper 22 for detecting the degree of wear of the second push rod 62. Alternatively, a wear detector is provided on both the first working surface and the second working surface of the first stopper 21 for detecting the degree of wear of the first push rod 61, the second push rod 62, and the third push rod 63, respectively.

[0071] In addition, the first specific embodiment of the present invention also provides a method for adjusting a worn push rod applicable to the above-mentioned air guide plate control mechanism of an air conditioner. The method for adjusting a worn push rod comprises the following steps:

[0072] Step S1: The first push rod 61 and the second push rod 62 are in use, for controlling the translation of the first component 1, and the third push rod 63 is in an idle state;

[0073] Step S2: When the wear of the first push rod 61 is greater than 0.5 mm, the first push rod 61 is adjusted to enter the idle state and the third push rod 63 is put into use state, so as to control the translation of the first component 1 through the third push rod 63 and the second push rod 62 .

[0074] It can be seen that in this wear push rod adjustment method, when the wear of the first push rod 61 is too large, the third push rod 63 can be adjusted to replace the first push rod 61, which is beneficial to extending the service life of the air conditioner guide plate control mechanism.

[0075] Furthermore, the worn push rod adjustment method also includes step S301: when the wear of the third push rod 63 is greater than 0.5 mm, the third push rod 63 is adjusted to enter an idle state, and the first push rod 61 enters a use state, so as to control the translation of the first component 1 through the first push rod 61 and the second push rod 62.

[0076] It can be seen that through step S301, the first push rod 61 and the third push rod 63 can be used alternately, thereby further extending the service life of the force rod shaft and even the air conditioner air guide plate control mechanism. The work flow can be seen in Figure 7 .

[0077] Alternatively, in a specific implementation, the worn push rod adjustment method also includes step S302: when the wear of the second push rod 62 is greater than 0.5 mm, the second push rod 62 is adjusted to enter an idle state and the third push rod 63 enters a use state, so as to control the translation of the first component 1 through the third push rod 63 and the first push rod 61.

[0078] It can be seen that through step S301, the third push rod 63 can be put into use instead of the second push rod 62 to avoid excessive wear of the second push rod 62 affecting the reliability of the air conditioning air guide plate control mechanism, thereby helping to extend the service life of the air conditioning air guide plate control mechanism.

[0079] Furthermore, the worn push rod adjustment method further includes step S4: when the wear of two of the first push rod 61, the second push rod 62, and the third push rod 63 is greater than 0.5 mm, the wear levels of the three push rods are compared, and the two push rods with the least wear are selected to control the translation of the first component 1, while the push rod with the most wear is placed in an idle state. Thus, step S4 helps maintain the force rod shaft and its push rods in optimal operating condition.

[0080] Second specific embodiment

[0081] The second embodiment of the present invention provides an air-conditioning air deflector control mechanism, which differs from the air-conditioning air deflector control mechanism provided in the first embodiment only in that:

[0082] See Figure 8 In the air deflector control mechanism for an air conditioner according to the second embodiment of the present invention, the second driver 4 and the lever shaft 5 are both mounted on the air conditioner body, and the first member 2 is fixedly connected to the second member 7. Therefore, when the lever shaft 5 rotates, the first member 2, the second member 7, and the air deflector 9 simultaneously translate relative to the air conditioner body, thereby controlling the air deflector 9 to move away from or closer to the air outlet 10.

[0083] In this case, the second member 7 can be slidably connected to the air conditioner body via a linear guide groove 1 (e.g., a T-shaped groove), or the first member 2 can be slidably connected to the air conditioner body via a linear guide groove (e.g., a T-shaped groove). Since the first member 2 and the second member 7 are fixedly connected, they form a fixed member, and as long as the fixed member can move linearly relative to the air conditioner body, it will be sufficient.

[0084] Specifically, the driving shaft of the second driver 4 is coaxially connected to the force rod shaft 5 , the body of the second driver 4 is fixed to the mechanism box 3 by screws, and the mechanism box 3 is fixed to the second component 7 .

[0085] Specifically, the force rod shaft 5 , the second driver 4 , the first working surface of the first stopper 21 , and the second working surface of the second stopper 22 are all located in the mechanism box 3 , and the mechanism box 3 is provided with a through hole for extending the second component 7 .

[0086] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
