Detailed implementation manners

[0055] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0056] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0057] The air guiding mechanism 10 according to the embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.

[0058] As Figures 1 to 6 shown, the air guiding mechanism 10 according to the embodiment of the first aspect of the present invention includes: a support 1, air guiding vanes 2 and a connecting rod 3. There are a plurality of air guiding vanes 2 spaced apart from each other on the support 1. Sound absorption grooves 21 are formed on at least part of the air guiding vanes 2, and the connecting rod 3 is connected to the plurality of air guiding vanes 2. That is to say, the connecting rod 3 can drive the plurality of air guiding vanes 2 to move relative to the support 1 to adjust the deflection angle of the air guiding vanes 2. When the air outlet device, such as the air outlet of an air conditioner indoor unit, blows air, the air outlet airflow will flow along the air guiding vanes 2 when passing through the air guiding vanes 2. Therefore, the flow direction of the air outlet airflow can be adjusted by adjusting the deflection angle of the air guiding vanes 2 to control the air outlet angle of the air outlet device.

[0059] Among them, air outlet noise is usually generated when the air outlet airflow contacts the vanes. In this application, by providing sound absorption grooves 21 on at least part of the air guiding vanes 2, when the air outlet noise is generated when the air outlet airflow contacts the air guiding vanes 2, the sound waves of the air outlet noise will be reflected and scattered after entering the sound absorption grooves 21. Therefore, the sound wave energy can be reduced during the process of sound wave reflection and scattering. That is, the sound wave energy of the air outlet noise can be absorbed by the sound absorption grooves 21 to reduce the air outlet noise, thereby improving the quietness of the air outlet through the air guiding mechanism 10.

[0060] It should be noted that the fact that sound absorption grooves 21 are formed on at least part of the air guiding vanes 2 means that the sound absorption grooves 21 can be provided on all the air guiding vanes 2, or only on some of the air guiding vanes 2, and no specific limitation is made here.

[0061] For the air guiding mechanism 10 according to the embodiment of the first aspect of the present invention, by providing sound absorption grooves 21 on at least part of the air guiding vanes 2, the sound wave energy of the air outlet noise can be absorbed during the air outlet process to reduce the air outlet noise, thereby improving the quietness of the air outlet through the air guiding mechanism 10.

[0062] According to some embodiments of the present invention, the plurality of air guiding vanes 2 include two first vanes 2a and a plurality of second vanes 2b. The plurality of second vanes 2b are arranged between the two first vanes 2a along the length direction of the support 1, and the sound absorption grooves 21 are provided on the second vanes 2b. That is, the sound absorption grooves 21 are provided on all the air guiding vanes 2 located between the air guiding vanes 2 at both side edges among the plurality of air guiding vanes 2. Therefore, when the air outlet airflow flows through the second vanes 2b, the sound wave energy of the air outlet noise can be absorbed by the sound absorption grooves 21 on the second vanes 2b to reduce the air outlet noise. By providing the sound absorption grooves 21 on the second vanes 2b, the coverage area of the sound absorption grooves 21 in the air outlet area can be preferably increased to improve the noise reduction effect of the air guiding mechanism 10.

[0063] According to some embodiments of the present utility model, there are multiple sound absorption grooves 21 distributed on both side surfaces of the air guiding vane 2 in the thickness direction. That is to say, the air guiding vane 2 with the sound absorption grooves 21 is provided with the sound absorption grooves 21 on both side surfaces in the thickness direction. It can be understood that due to the different deflection directions of the air guiding vane 2, the side surface of the air guiding vane 2 in contact with the outlet air flow is also different. For example, when the air guiding vane 2 deflects to the left and the left side surface of the air guiding vane 2 is in contact with the outlet air flow, the sound wave energy of the outlet air noise can be absorbed by the sound absorption grooves 21 on the left side surface of the air guiding vane 2. Similarly, when the air guiding vane 2 deflects to the right and the right side surface of the air guiding vane 2 is in contact with the outlet air flow, the sound wave energy of the outlet air noise can be absorbed by the sound absorption grooves 21 on the right side surface of the air guiding vane 2. Therefore, by arranging the sound absorption grooves 21 to be multiple on both side surfaces of the air guiding vane 2 in the thickness direction, it can be ensured that when the air guiding vane 2 is in different deflection directions, the outlet air noise can be reduced through the sound absorption grooves 21 on the corresponding side surfaces, so as to improve the noise reduction effect of the air guiding mechanism 10.

[0064] In a specific example, multiple sound absorption grooves 21 are formed on both side surfaces of the second vane 2b in the thickness direction, so as to further improve the weakening effect of the second vane 2b on the outlet air noise.

[0065] According to some embodiments of the present utility model, the multiple air guiding vanes 2 include two first vanes 2a and multiple second vanes 2b. The multiple second vanes 2b are arranged between the two first vanes 2a along the length direction of the support 1, and the first vane 2a is formed with a ventilation hole 22 penetrating along the thickness direction. It can be understood that when the air guiding vane 2 deflects to the limit angle in one direction, for example, the air guiding vane 2 can swing left and right. When the air guiding vane 2 swings left to the limit angle, an included angle area is formed between the leftmost air guiding vane 2, that is, the first vane 2a on the left side, and the left inner wall surface of the air duct. Therefore, by arranging the ventilation hole 22 on the first vane 2a, when the two first vanes 2a on both sides deflect to the limit angles on the corresponding sides, the air flow entering the included angle position between the first vane 2a and the inner wall surface on the corresponding side of the air duct can be discharged through the ventilation hole 22, so as to reduce the temperature difference between the windward side surface and the leeward side surface of the first vane 2a, and reduce the risk of condensation on the leeward side surface of the first vane 2a.

[0066] According to some embodiments of the present utility model, the ventilation hole 22 is in the shape of a strip perpendicular to the outlet air direction. Thus, the ventilation area of the ventilation hole 22 can be better increased, that is, the ventilation volume of the first vane 2a can be improved, so as to further reduce the temperature difference between the windward side surface and the leeward side surface of the first vane 2a, and reduce the risk of condensation on the leeward side surface of the first vane 2a.

[0067] According to some embodiments of the present utility model, the support 1, a plurality of air guiding vanes 2 and the connecting rod 3 are integrally formed. Thus, the steps of separately manufacturing and sequentially installing the plurality of air guiding vanes 2 and the connecting rod 3 can be omitted, thereby improving the installation efficiency of the air guiding mechanism 10. At the same time, the number of molds for separately producing the support 1, the plurality of air guiding vanes 2 and the connecting rod 3 can be reduced to lower the production management cost of the air guiding mechanism 10.

[0068] In a specific example, the integrally formed part composed of the support 1, a plurality of air guiding vanes 2 and the connecting rod 3 is a flexible PP material part.

[0069] In a specific example, the air guiding mechanism 10 is an integrally formed part.

[0070] According to some embodiments of the present utility model, the air guiding vane 2 includes an air guiding portion 23 and a flexible deformation structure 24. The air guiding portion 23 is flexibly connected to the support 1 and the connecting rod 3 respectively through the flexible deformation structure 24. That is to say, the air guiding portion 23 is connected to the support 1 through the flexible deformation structure 24 and can move relative to the support 1 by deforming through the flexible deformation structure 24. The air guiding portion 23 is also connected to the connecting rod 3 through the flexible deformation structure 24 and can move relative to the connecting rod 3 by deforming through the flexible deformation structure 24. Thus, during the movement of the connecting rod 3, the air guiding portion 23 can be driven to swing relative to the support 1 through the deformation of the flexible deformation structure 24 to adjust the deflection direction of the air guiding portion 23, thereby realizing the adjustment of the air outlet direction.

[0071] According to some embodiments of the present utility model, the flexible deformation structure 24 includes a first deformation portion 241, a second deformation portion 242 and a connecting portion 243. The first deformation portion 241 and the second deformation portion 242 are respectively arranged on the upstream side and the downstream side of the connecting portion 243. The connecting portion 243 is connected to the support 1 and the connecting rod 3 respectively through the first deformation portion 241 and the second deformation portion 242. The thicknesses of the first deformation portion 241 and the second deformation portion 242 are less than the thickness of the connecting portion 243. The air guiding portion 23 is arranged on the connecting portion 243.

[0072] That is to say, the air guiding portion 23 is connected to the support 1 through the connecting portion 243 and the first deformation portion 241. At the same time, the air guiding portion 23 is connected to the connecting rod 3 through the connecting portion 243 and the second deformation portion 242. And because the thicknesses of the first deformation portion 241 and the second deformation portion 242 are less than the thickness of the connecting portion 243, the first deformation portion 241 and the second deformation portion 242 are more easily deformed. Therefore, when the connecting rod 3 moves, the connecting portion 243 can be driven to move relative to the support 1 through the deformation of the first deformation portion 241 and the second deformation portion 242, so that the air guiding portion 23 can be driven to move relative to the support 1 through the connecting portion 243 to adjust the deflection direction and angle of the air guiding portion 23.

[0073] According to some embodiments of the present utility model, the air guiding blade 2 includes an air guiding portion 23. The air guiding portion 23 includes a first portion 231 and a second portion 232. The second portion 232 is connected to the downstream side of the first portion 231. The first portion 231 and the second portion 232 jointly define an avoidance notch 25 on the upstream side of the second portion 232. The connecting rod 3 is located within the avoidance notch 25. Thus, by providing the avoidance notch 25, while avoiding the movement of the connecting rod 3, at least a part of the air guiding portion 23 can be located on the downstream side of the connecting rod 3. As a result, the second portion 232 of the air guiding portion 23 located on the downstream side of the connecting rod 3 can better guide the air flow passing through the connecting rod 3, thereby enhancing the air guiding effect of the air guiding portion 23.

[0074] The following describes an air conditioner indoor unit according to an embodiment of the second aspect of the present utility model with reference to the accompanying drawings.

[0075] As Figures 7 to 25 shown, the air conditioner indoor unit according to an embodiment of the second aspect of the present utility model includes: a housing component 20, an air guiding mechanism 10, and a driving mechanism 30. The housing component 20 forms an air outlet passage 41. The air guiding mechanism 10 is disposed within the air outlet passage 41. The driving mechanism 30 is disposed on the housing component 20 and is connected to the connecting rod 3 to drive the air guiding blade 2 to swing. Therefore, when the air conditioner indoor unit blows air, the air guiding blade 2 can be driven to swing relative to the support 1 through the cooperation of the driving mechanism 30 and the connecting rod 3. Thus, the air flow direction within the air outlet passage 41 can be adjusted by multiple air guiding blades 2 to achieve the adjustment of the air outlet direction of the air conditioner indoor unit.

[0076] Among them, since at least part of the air guiding blade 2 is formed with a sound absorption groove 21, when the air flow blowing out within the air outlet passage 41 contacts the air guiding blade 2 to generate an air outlet noise, the sound wave of the air outlet noise will be reflected and scattered after entering the sound absorption groove 21. Thus, the sound wave energy can be reduced during the process of sound wave reflection and scattering. That is, the sound wave energy of the air outlet noise can be absorbed through the sound absorption groove 21 to reduce the air outlet noise, thereby enhancing the quietness of the air blowing of the air conditioner indoor unit.

[0077] For the air conditioner indoor unit according to an embodiment of the second aspect of the present utility model, by providing the sound absorption groove 21 on at least part of the air guiding blade 2, the sound wave energy of the air outlet noise can be absorbed during the air blowing process to reduce the air outlet noise, thereby enhancing the quietness of the air blowing of the air conditioner indoor unit.

[0078] Among them, the air conditioner indoor unit can be a floor-standing unit or a wall-mounted unit. The type of the air conditioner indoor unit is not specifically limited here.

[0079] In a specific example, the air conditioner indoor unit is a wall-mounted unit, and the housing component 20 is the chassis of the air conditioner indoor unit.

[0080] According to some embodiments of the present utility model, a first installation groove 42 is formed on the inner side surface of the air outlet passage 41, and the support 1 is disposed in the first installation groove 42. Thus, by accommodating at least a part of the support 1 through the first installation groove 42, it is possible to preferably reduce or avoid the side surface of the support 1 protruding from the inner side surface of the air outlet passage 41 towards the guide vane 2, thereby avoiding the support 1 from blocking the air flow on the upstream side and increasing the air volume loss, so as to improve the air conditioning efficiency of the air conditioner indoor unit. In addition, by providing the first installation groove 42, it is convenient to position the support 1 during installation, that is, the first installation groove 42 can accurately indicate the installation position of the support 1, thereby reducing the difficulty of installing the support 1 on the housing component 20 and improving the assembly efficiency of the air guide mechanism 10. Moreover, through the first installation groove 42, a limit to the support 1 can be formed, thereby improving the stability of the support 1 installed on the housing component 20 and enhancing the connection strength between the air guide mechanism 10 and the housing component 20.

[0081] According to some embodiments of the present utility model, a plug-in groove 43 and a clamping groove 44 are formed on the inner side surface of the air outlet passage 41, and a plug-in protrusion 11 and a buckle 12 are formed on the support 1. The plug-in protrusion 11 is in plug-in fit with the plug-in groove 43 to limit the movement of the support 1 relative to the housing component 20 in the thickness direction, and the buckle 12 is in clamping fit with the clamping groove 44 along the thickness direction of the support 1. That is to say, the support 1 is fixed on the housing component 20 through the plug-in fit of the plug-in groove 43 and the plug-in protrusion 11 and the clamping fit of the clamping groove 44 and the buckle 12. Thus, the connection structure between the support 1 and the housing component 20 can be preferably simplified to reduce the difficulty of installing the support 1 on the housing component 20 or removing it from the housing component 20. In addition, the connection stability between the support 1 and the housing component 20 can be preferably improved to enhance the connection strength between the air guide mechanism 10 and the housing component 20.

[0082] According to some embodiments of the present utility model, both the plug-in protrusion 11 and the buckle 12 are formed on the side surface of the support 1 facing away from the guide vane 2. Thus, it is possible to avoid the plug-in protrusion 11 and the buckle 12 occupying the space on the side surface of the support 1 facing the guide vane 2, thereby avoiding the plug-in protrusion 11 and the buckle 12 arranged on the side surface of the support 1 facing the guide vane 2 from blocking the air flow, that is, while ensuring the connection strength between the support 1 and the housing component 20, the air outlet resistance at the plug-in protrusion 11 and the buckle 12 can be avoided.

[0083] In a specific example, such as Figure 11As shown, a plurality of insertion protrusions 11 and snap fasteners 12 are provided at intervals along the length direction of the support 1. The insertion protrusions 11 are provided at the upstream end of the lower side surface of the support 1 and protrude from the upstream end side surface of the support 1. The snap fasteners 12 are provided on the lower side surface of the support 1 and are arranged adjacent to the downstream end of the support 1. The insertion slot 43 is formed on the side surface of the upstream end of the first installation slot 42, and the clamping slot 44 is formed on the inner bottom wall of the first installation slot 42. During the process of installing the support 1 onto the housing component 20, first, align the plurality of insertion protrusions 11 with the plurality of insertion slots 43 and insert them. Then, press down the downstream end of the support 1 to make the support 1 rotate around the connection position between the upstream end of the support 1 and the housing component 20 until the plurality of snap fasteners 12 are respectively clamped and engaged with the corresponding plurality of clamping slots 44.

[0084] According to some embodiments of the present invention, a disassembly hole 45 communicating with the clamping slot 44 is further formed on the outer surface of the housing component 20, and the disassembly hole 45 is opposite to the clamping position of the snap fastener 12 and the clamping slot 44. Therefore, when it is necessary to remove the support 1 from the housing component 20, a tool or hand can be passed through the disassembly hole 45 to release the cooperation between the snap fastener 12 and the clamping slot 44, so as to reduce the difficulty of removing the support 1 from the housing component 20. In addition, the cooperation position between the snap fastener 12 and the clamping slot 44 is more intuitive through the disassembly hole 45, so that it can be accurately judged whether the snap fastener 12 is clamped in place with the clamping slot 44 through the disassembly hole 45.

[0085] According to some embodiments of the present invention, a limiting groove 13 is formed on one side edge of the support 1 in the width direction, and the limiting groove 13 penetrates the support 1 along the thickness direction of the support 1. A limiting lug 46 located in the air outlet passage 41 is formed on the housing component 20, and the limiting lug 46 is located in the limiting groove 13 to limit the movement of the support 1 relative to the housing component 20 in the length direction. Therefore, through the cooperation between the limiting lug 46 and the limiting groove 13, the connection stability between the support 1 and the housing component 20 can be improved to prevent the movement of the air guiding mechanism 10 after installation from affecting the air guiding effect.

[0086] According to some embodiments of the present invention, the driving mechanism 30 includes a driving motor 51, a crank 52, and a motor seat 53. One end of the crank 52 is connected to the output shaft 512 of the driving motor 51, and the other end of the crank 52 is rotatably connected to the connecting rod 3. Thus, the crank 52 is driven to swing by the output shaft 512 of the driving motor 51 to drive the connecting rod 3 to move, and then the air guiding blade 2 is driven by the connecting rod 3 to adjust the deflection angle of the air guiding blade 2.

A part of the motor seat 53 is inserted and matched with the second installation slot 47, and a connecting sleeve post 5311 inserted and matched with the screw post 48 is formed on the motor seat 53.

[0087] That is to say, when the motor seat 53 is plugged into and matched with the second mounting groove 47, the connecting sleeve 5311 can be sleeved on the screw column 48, and the connecting sleeve 5311 and the screw column 48 can be fixed by screws, thereby realizing the fixed installation of the motor seat 53 on the housing component 20. Among them, by setting the second mounting groove 47, a good positioning and holding effect can be provided for the fixation of the motor seat 53. Specifically, when the motor seat 53 is installed on the housing component 20, the motor seat 53 can be first plugged into and matched with the second mounting groove 47 to realize positioning, and in the process of connecting the motor seat 53 through the connecting sleeve 5311 and the screw column 48 by the screw fastener 533, the second mounting groove 47 can limit the motor seat 53, so that the connecting sleeve 5311 and the screw column 48 are in a facing state, thereby reducing the difficulty of connecting the motor seat 53 with the housing component 20 to improve the assembly efficiency of the drive mechanism 30.

[0088] In a specific example, the output shaft 512 of the driving motor 51 is flat, a flat matching hole 521 is formed at one end of the crank 52, the output shaft 512 is inserted into the matching hole 521, a clamping shaft 522 is formed at the other end of the crank 52, and a clamping hole 31 is formed on the connecting rod 3 to be clamped with the clamping shaft 522. In addition, two connecting ears 513 are formed on the motor body 511, and a limited slot 5313 and a connecting column 5314 are formed on the main body 531, one of the connecting ears 513 is inserted into the limited slot 5313, and the other connecting ear 513 is arranged opposite to the connecting column 5314, and the connecting ears 513 and the connecting column 5314 can be connected by a screw fastener 533.

[0089] According to some embodiments of the utility model, the motor seat 53 includes a main body 531 and a limiting portion 532 disposed on the main body 531, and an avoidance hole 5312 is formed on the main body 531. The driving motor 51 includes a motor body 511 and an output shaft 512. The motor body 511 is disposed on one side of the main body 531, and the output shaft 512 is inserted into the avoidance hole 5312. The limiting portion 532 is located on the side of the main body 531 away from the motor body 511 and is spaced relative to the avoidance hole 5312. In other words, the connection position of the crank 52 and the output shaft 512 is located in the space between the limiting portion 532 and the main body 531. Therefore, after the crank 52 is installed on the output shaft 512, the limiting portion 532 can block the crank 52 from coming off the output shaft 512 from the side of the crank 52 away from the main body 531, thereby improving the connection stability between the crank 52 and the output shaft 512.
