Description

Technical Field

[0001] This invention relates to air conditioning technology, and in particular to an air conditioner and its swing device. Background Technology

[0002] With the development of air conditioning technology, the appearance and functions of air conditioners are constantly being updated and replaced, and various new technologies are emerging one after another.

[0003] However, there are very few innovative designs for the swing mechanism of air conditioners. For example, for wall-mounted air conditioner indoor units, existing solutions typically involve installing an air guide vane and a swivel assembly at the air outlet. The air guide vane adjusts the vertical angle of the air outlet, while the swivel assembly swings the air left and right. The structures of floor-standing air conditioner indoor units are also largely similar. Existing air conditioners widely adopt the aforementioned swing mechanism, resulting in a uniform user experience and product appearance, making it difficult to elevate the product's perceived quality.

[0004] Therefore, how to innovate in the swing structure has become a technical problem that the air conditioning industry urgently needs to solve. Summary of the Invention

[0005] One objective of this invention is to provide a novel air-swing device and a corresponding air conditioner to enhance product differentiation and user experience.

[0006] A further objective of this invention is to make the swing force of the swing device stronger.

[0007] A further objective of the present invention is to make the swing mode of the swing device adjustable.

[0008] On one hand, the present invention provides a swing device for installation at the air outlet of an air conditioner, which includes multiple swing blades for synchronously rotating on a fixed axis to guide the air outlet direction; and each swing blade includes multiple layers of blades arranged at intervals.

[0009] Optionally, each of the blades further includes a fixing plate, and each blade is fixed to a different part of the fixing plate along its length.

[0010] Optionally, in each of the oscillating blades, each blade is entirely flat and parallel to each other.

[0011] Optionally, in each of the blades, the ratio of the spacing between any two adjacent blades to the thickness of either blade is between 6 and 7.

[0012] Optionally, at least one of the blades in each of the swing blades has at least one ventilation hole.

[0013] Optionally, in the blade with the ventilation holes, there are multiple ventilation holes, all of which are elongated and are spaced apart along the width direction of the ventilation holes.

[0014] Optionally, for a plurality of ventilation holes of a blade, the length of the ventilation holes gradually increases from bottom to top.

[0015] Optionally, in each of the multiple layers of blades of the oscillating blade, the spacing between at least two adjacent layers of blades is adjustable.

[0016] Optionally, each of the blades further includes a connecting plate, each blade is mounted at a different location along the length of the connecting plate, and at least one blade can move along the length of the connecting plate to adjust its spacing distance from adjacent blades.

[0017] On the other hand, the present invention also provides an air conditioner, comprising:

[0018] The casing has an air outlet; and

[0019] At least one swing device as described in any of the above is provided at the air outlet.

[0020] In the air conditioner and its swing device of the present invention, each swing blade includes multiple layers of blades spaced apart, and each blade can guide the airflow direction, thereby enhancing the airflow guiding ability of each swing blade. Furthermore, the airflow experiences an acceleration effect when passing through the gap between two adjacent blades, further strengthening the swing blade's guiding force and enabling it to more effectively reach the preset swing direction. Moreover, this multi-layered blade structure increases the layering of the airflow, making the airflow more comfortable for the human body. In addition, because each swing blade has multiple layers of blades, the number of swing blades in the entire swing device is reduced, making the linkage mechanism of the swing device relatively simple and reducing the probability of malfunction.

[0021] Furthermore, in the air conditioner and its swing device of the present invention, ventilation holes are provided on the blades, which can increase the exchange of airflow on both sides of each blade, making the airflow relatively gentle. Moreover, it can also prevent condensation from appearing on the blade surface.

[0022] Furthermore, in the air conditioner and its swing device of the present invention, the spacing between at least two layers of blades is adjustable. By changing the blade spacing, the airflow velocity between the two blades can be changed, thereby changing the overall flow velocity of the swing airflow. Therefore, the present invention can adjust the air outlet speed and change the swing mode by adjusting the blade spacing, which is a very ingenious structure.

[0023] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

Those skilled in the art should be able to understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] This invention provides an air conditioner and a swing device. The air conditioner in this invention can be a wall-mounted air conditioner, a floor-standing air conditioner, a ceiling-mounted air conditioner, a window air conditioner, or other various types of air conditioners. Figure 1The illustration shows an example of a wall-mounted air conditioner. An air conditioner can consist of an evaporator, condenser, compressor, throttling device, and other necessary components forming a vapor compression refrigeration cycle system, which outputs cool / hot air via a fan to achieve cooling and heating of the indoor environment.

[0044] Figure 1 This is a schematic diagram of the structure of an air conditioner according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of a swing device according to an embodiment of the present invention; Figure 3 yes Figure 2 Enlarged view of point B.

[0045] like Figures 1 to 3 As shown, the swing device 100 of this embodiment is installed at the air outlet 12 of an air conditioner to swing the air at the air outlet 12, causing the air direction to change repeatedly within a certain range. For example, for wall-mounted air conditioners, the swing device 100 is usually used for left-right swinging; for floor-standing air conditioners, the swing device 100 is usually used for up-down swinging. The swing device 100 includes multiple swing blades 80. The swing blades 80 are used to synchronously guide the air outlet direction at the air outlet 12 by rotating around a fixed axis, that is, each swing blade 80 rotates around its own axis. Figure 3 The middle label is x4.

[0046] for Figure 1 The wall-mounted air conditioner shown is typically a long strip-shaped casing 10 extending horizontally (the x-axis is used to represent this direction in each figure), and its air outlet 12 is also long strip-shaped. The oscillating blades 80 of the oscillation device 100 can be arranged along the length x-direction of the casing 10 to perform lateral oscillation at the air outlet 12, that is, left-right oscillation.

[0047] like Figure 3 As shown, each blade 80 comprises multiple layers of blades arranged at intervals. For example... Figure 3 In the embodiment described, each oscillating blade 80 includes three blades 81, 82, and 83. The number of blades included in different oscillating blades 80 of the oscillating device 100 may be the same or different.

[0048] In the air conditioner and its swing device 100 of this embodiment, each swing blade 80 includes multiple layers of blades 81, 82, and 83 spaced apart. Each blade 81, 82, and 83 can guide the airflow direction, thus enhancing the airflow guiding ability of each swing blade 80. Furthermore, the airflow experiences an acceleration effect when passing through the gap between adjacent blades 81, 82, and 83, further strengthening the guiding force of the swing blade 80 and enabling it to more effectively reach the preset swing direction. Moreover, this multi-layered blade structure 81, 82, and 83 increases the layering of the airflow, making the airflow more comfortable for the human body. In addition, since each swing blade 80 has multiple layers of blades 81, 82, and 83, the number of swing blades 80 in the entire swing device 100 is reduced, making the linkage mechanism of the swing device 100 relatively simple, with fewer rotating friction pairs, thus reducing the probability of malfunction.

[0049] Figure 4 yes Figure 2 A schematic diagram of the structure of one of the swing blades in the swing device shown.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, each blade 80 also includes a fixing plate 85, which has a length direction. Each blade 81, 82, and 83 is fixed to different parts of the fixing plate 85 along its length. Specifically, the fixing plate 85 and each blade 81, 82, and 83 can be integrally formed as a single piece.

[0051] In some embodiments, such as Figure 3 and Figure 4 As shown, for a single blade 80, each of its blades 81, 82, and 83 can be made into a flat plate shape and parallel to each other to facilitate the forming and processing of the blade 80. Additionally, for a single blade 80, the spacing 'a' between any two adjacent blades can be set (refer to...). Figure 3 The ratio of the thickness of the blade to the thickness of either of the two blades is between 6 and 7, preferably between 6.15 and 6.5, to avoid the problem that too large an interval will result in a weak sense of air delivery layering, while too small an interval will result in airflow stagnation and poor airflow.

[0052] In some embodiments, such as Figure 4 As shown, at least one air vent 801 can be provided on at least one blade 81, 82, or 83 of each oscillating blade 80. Specifically, each blade 81, 82, or 83 can have an air vent 801. Of course, only some blades can have air vents 801. By providing air vents, the airflow exchange between the two sides of the blades 81, 82, and 83 can be increased while the blades 81, 82, and 83 are oscillating strongly, resulting in a relatively gentle airflow. Moreover, it can also prevent condensation from forming on the surface of the blades 81, 82, and 83.

[0053] like Figure 4 As shown, for each blade with ventilation holes 801, there are multiple ventilation holes 801, all of which are elongated, specifically elongated arc-shaped, and arranged at intervals along the width direction of the ventilation holes 801. Specifically, for the multiple ventilation holes 801 of a blade, the length of the ventilation holes 801 gradually increases from bottom to top, thus enhancing the wind-reducing effect.

[0054] Figure 5 yes Figure 2 An exploded view of a portion of the swing device shown.

[0055] In some embodiments, such as Figures 3 to 5 As shown, each oscillating blade 80 is rotatably mounted directly or indirectly to the housing 10 of the air conditioner (rotation axis is x4), and each oscillating blade 80 has a connecting arm 84. The swing device 100 also includes a connecting rod 93, the ends of the connecting arms 84 of each oscillating blade 80 being rotatably connected to different parts of the connecting rod 93 along its length, with the rotation axis being x3, so that each oscillating blade 80 can rotate in conjunction (around x4).

[0056] More specifically, such as Figure 3 As shown, the swing device 100 also includes a motor 91 and a crank 92. One end of the crank 92 is rotatably connected to the motor 91, with the rotation axis being x1. The other end of the crank 92 is rotatably connected to the connecting rod 93, with the rotation axis being x2. When the motor 91 rotates forward and backward, it drives the crank 92 to rotate back and forth around x1. The crank 92 drives the connecting rod 93 to move back and forth, thereby driving each swing blade 80 to swing back and forth around x4. In addition, various other existing methods can also be used to achieve the linkage swing of each swing blade 80. These methods are extremely common in the air conditioning field and will not be described in detail here.

[0057] like Figure 3 and Figure 5 As shown, multiple first mounting holes 931 are provided at different locations along the length of the connecting rod 93 to allow the shaft at the end of the connecting arm 84 to be inserted therein. Furthermore, the swing device 100 may also include a mounting plate 94. Figure 3 (The mounting plates corresponding to each swing blade on the left side are hidden). The mounting plate 94 is installed on the housing 10 of the air conditioner. Multiple mounting shafts 941 are provided on the mounting plate 94 so that they can be rotatably installed in the second mounting hole 841 on the connecting arm 84. The central axis of the second mounting hole 841 is x4.

[0058] Figure 6 This is a partial structural schematic diagram of the swing device according to another embodiment of the present invention. Figure 7 yes Figure 6 A schematic diagram of the structure of one of the swing blades in the swing device shown.

[0059] In some embodiments, such as Figure 6 and Figure 7 As shown, in each oscillating blade 80 with multiple layers of blades 81, 82, and 83, the spacing between at least two adjacent layers of blades is adjustable. For example, if there are only two layers of blades, the spacing between those two layers is adjustable. If there are three layers of blades, the spacing between the first and second layers can be adjusted, or the spacing between the second and third layers can be adjusted, or both spacings can be adjusted. For example... Figure 6 As shown, each oscillating blade 80 includes three layers of blades 81, 82, and 83. The two spacings formed by the three blades 81, 82, and 83—namely, the spacing 'a' between blade 81 and blade 82, and the spacing 'b' between blade 81 and blade 83—are adjustable. Figure 6 In the leftmost oscillating blade 80, the spacing between blades 81, 82, and 83 is the default spacing. The spacing between blades 81, 82, and 83 in the middle oscillating blade 80 is increased, while the spacing between blades 81, 82, and 83 in the rightmost oscillating blade 80 is decreased. Thus, by changing the spacing between blades 81, 82, and 83, the airflow velocity between those two blades 81, 82, and 83 can be altered, thereby changing the overall velocity of the oscillating airflow. Therefore, this embodiment of the invention allows for adjustment of the outlet airflow velocity by adjusting the spacing between blades 81, 82, and 83, a very ingenious structure.

[0060] Figure 8 yes Figure 7 A schematic exploded view, Figure 9 yes Figure 8 Enlarged view of point C.

[0061] In some embodiments of the present invention, such as Figures 7 to 9 As shown, each blade 80 also includes a connecting plate 88. The connecting plate 88 may be elongated. Each blade 81, 82, and 83 is mounted at a different location along the length of the connecting plate 88. Furthermore, at least one blade 81, 82, or 83 may move along the length of the connecting plate 88 (parallel to the x-direction) to adjust its spacing from adjacent blades 81, 82, and 83. That is, it is not necessary for every blade 81, 82, and 83 to be movable; as long as some blades 81, 82, and 83 can move, the spacing can be adjusted. The remaining blades 81, 82, and 83 may be fixed to the connecting plate 88 or integrally formed into the connecting plate 88.

[0062] In some embodiments of the present invention, in order to simplify the processing of the connecting plate 88 and to make the adjustment modes more diverse, each blade 81, 82, 83 of the oscillating blade 80 can be moved along the length direction of the connecting plate 88.

[0063] In some embodiments of the present invention, such as Figure 7 and Figure 8As shown, each movable blade 81, 82, 83 can be provided with an insertion through hole 802 to allow the connecting plate 88 to be inserted therein, so as to realize the connection between the blade 81, 82, 83 and the connecting plate 88.

[0064] In some embodiments, such as Figure 7 and Figure 8 As shown, in order to position each blade 81, 82, 83, the connecting plate 88 can be provided with a plurality of positioning through holes 882 arranged along its length direction, and at least one hole wall of each through hole 802 protrudes to form a positioning protrusion 8021. Figure 7 A positioning protrusion 8021 is indicated by a dashed ellipse. Specifically, positioning protrusions 8021 can be provided on each of the two opposite walls of the through hole 802, thus forming two positioning protrusions 8021. After the blades 81, 82, and 83 move to the selected position, the positioning protrusions 8021 are inserted into the positioning through hole 882 at that position, fitting snugly within it to position the blades 81, 82, and 83. Furthermore, the blades 81, 82, and 83 are allowed to elastically deform and disengage from the positioning through hole 882 due to external force. Thus, the user can move the blades 81, 82, and 83 by force; otherwise, the blades 81, 82, and 83 will remain securely in the user-selected position.

[0065] The present invention, through the above-described structure, can position blades 81, 82, and 83, and can easily adjust the positions of blades 81, 82, and 83. The structural design is very simple and reasonable, and the cost is lower.

[0066] This invention also provides an air conditioner, which generally includes a housing 10 and at least one swing device. The housing 10 has an air outlet 12, and the swing device is the swing device 100 described in any of the above embodiments, which is disposed at the air outlet 12 to swing the air.

[0067] like Figure 1 As shown, the air conditioner is a wall-mounted air conditioner, and the casing 10 can be a long strip arranged horizontally in the length direction. The casing 10 defines a space for accommodating the various components of the wall-mounted air conditioner. The casing 10 has an air outlet 12 for discharging the airflow inside. The discharged airflow refers to the airflow that is accelerated by the fan inside the casing 10 to flow through the air outlet 12 for regulating the indoor environment, such as cold air in cooling mode, hot air in heating mode, and fresh air in fresh air mode, etc.

[0068] The air conditioner also includes an air guide plate 50. The air guide plate 50 is rotatably mounted at the air outlet 12 of the wall-mounted air conditioner about a rotation axis parallel to its length direction, and is used to guide the air outlet 12. The air guide plate 50 may be a long strip with its length direction parallel to the length direction of the air outlet 12, and the rotation axis of the air guide plate 50 is parallel to its length direction.

[0069] Figure 10 yes Figure 1 The diagram shows the structure of the air guide plate in the air conditioner. Figure 11 yes Figure 10 Enlarged view of point D.

[0070] like Figure 10 and Figure 11 As shown, the air guide plate 50 includes one air guide section 501 or multiple air guide sections 501 arranged and fixedly connected along the length of the air guide plate 50. Providing multiple air guide sections 501 can improve the overall structural stability of the air guide plate 50. For example... Figure 10 As shown, the air guide plate 50 includes two air guide sections 501. Each air guide section 501 includes an outer plate 51, multiple inner plates, and two end plates 54 and 55. For example... Figure 2 and Figure 3 As shown, there are two inner panels, inner panel 52 and inner panel 53, forming a three-layer air guide plate. Of course, the number of inner panels can also be three, four, or more. See below for reference. Figures 10 to 11 Taking the three-layer air guide plate as an example, the structure of the air guide plate 50 will be further introduced.

[0071] like Figure 10 and Figure 11As shown, the outer plate 51 and each inner plate 52, 53 can be plate-shaped for air guidance. Multiple inner plates 52, 53 are arranged sequentially at intervals along a direction away from the first side 511 of the outer plate 51. The two large surfaces of the outer plate 51 used for air guidance are the first side 511 and the second side 512, respectively. An air outlet gap 515 is formed between the outer plate 51 and adjacent inner plates 52, and an air outlet gap 525 is also formed between adjacent inner plates 52, 53, to allow airflow to escape. Two end plates 54 are located at both ends of the length direction of each air guide section 501. One end of the outer plate 51 and each of the multiple inner plates 52, 53 is fixed to one end plate 54, and the other end is fixed to another end plate 55, so that the various parts of the air guide section 501 form a stable whole. In addition, each air guide section 501 may include at least one connecting section 56, located between the two end plates 54 and 55, and also used for fixed connection with the outer panel 51 and multiple inner panels 52 and 53, making the structure of the air guide section 501 more stable. The outer panel 51, each inner panel 52 and 53, the two end plates 54 and 55, and the connecting section 56 can be integrally molded, for example, as a single injection-molded part. An installation shaft 57 may be provided on the end plate 54 for rotatable installation on the housing 10 of the wall-mounted air conditioner.

[0072] The air guide plate 50 of this embodiment includes an outer plate 51 and multiple inner plates 52 and 53, which makes the air guide plate 50 a multi-layer structure. When the air guide plate 50 guides the air, part of the outgoing airflow is guided by the outer plate 51, while another part of the outgoing airflow can enter the air outlet gap between the outer plate 51 and the adjacent inner plate, as well as the air outlet gap between two adjacent inner plates 52 and 53. The outer plate 51 and the multiple inner plates 52 and 53 jointly guide the outgoing airflow direction, realizing a multi-layer guiding effect. This makes the direction of the airflow discharged from the air outlet 12 uniform, and the airflow is more smoothly organized, thereby improving the user's comfort.

[0073] In some embodiments, such as Figure 10 and Figure 11 As shown, the orthographic projection of the inner plate 52 onto the outer plate 51 falls on the outer plate 51, rather than on its extension line. The orthographic projection of the inner plate 53 onto the inner plate 52 falls on the inner plate 52, rather than on its extension line. That is, the width of the inner plate 52 is smaller than that of the outer plate 51, and the width of the inner plate 53 is smaller than that of the inner plate 52. The width direction of the outer plate 51 is the direction in which the airflow flows along the first side surface 511 of the guide plate 50. The width direction of each inner plate 52 and 53 is the direction in which the airflow flows along the inner plates 52 and 53. More preferably, the width of the inner plate 53 is less than 1 / 2 the width of the inner plate 52, and the width of the inner plate 52 is less than 1 / 3 the width of the outer plate 51.

[0074] Thus, the outer side of the inner plate 53 forms a low-speed zone, and the area between the inner plate 53 and the inner plate 52 forms an acceleration zone. The pressure increases significantly when the airflow passes through the acceleration zone, which helps to increase the air delivery distance. The area between the inner plate 52 and the outer plate 51 is a guide zone, mainly used to guide the airflow direction of the main airflow component. Furthermore, the reason why the width of each inner plate 52 and 53 is designed to be smaller than that of the outer plate 51 in this embodiment is to avoid excessively long guide distances in the air outlet intervals, which would lead to excessive airflow resistance and excessively affect the airflow volume and speed of the air outlet 12. Moreover, the width of the inner plate is smaller the further away from the outer plate 51, which also facilitates the smooth entry of the airflow into each air outlet interval and its guidance by the inner plates 52 and 53. Whether the airflow flows towards the first side 511 at an angle parallel to the outer plate 51 or at an angle towards the first side 511, it can enter each air outlet interval more effectively.

[0075] In some embodiments, such as Figure 1 As shown, the air guide plate 50 can be used to guide the air supply direction of the air outlet 12, so that the wall-mounted air conditioner also includes an outer guide plate 60, which is rotatably disposed at the air outlet 12 for opening and closing the air outlet 12.

[0076] A wall-mounted air conditioner is the indoor unit of a split-type wall-mounted room air conditioner that uses a vapor compression refrigeration cycle system for cooling / heating. For example... Figure 1 As shown, the interior of the casing 10 houses a heat exchanger and a fan. The heat exchanger, throttling device, and compressor, condenser, and other refrigeration components located in the outdoor unit of the air conditioner are connected via pipes to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the interior of the casing 10 through the air inlet 11 at the top of the casing 10, completes forced convection heat exchange with the heat exchanger, forms heat exchange air, and enters the air duct. The fan is preferably a cross-flow fan with its axis parallel to the length direction of the casing 10, and is located at the inlet of the air duct.

[0077] Figure 12 This is a schematic diagram of the structure of a wall-mounted air conditioner indoor unit according to another embodiment of the present invention; Figure 13 yes Figure 12 Enlarged view at point M; Figure 14 yes Figure 12 A schematic diagram of the structure of the external guide plate in the indoor unit of a wall-mounted air conditioner; Figure 15 yes Figure 12 The diagram shows a partial exploded view of the air guide plate in the indoor unit of a wall-mounted air conditioner.

[0078] like Figures 12 to 15As shown, in some embodiments, the outer guide plate 60 also has at least one receiving portion 65 for accommodating at least one moisture storage module 66, or no moisture storage module 66, directly accommodating water. The moisture storage module 66 is made of a material that easily absorbs and releases water, and when any part of the moisture storage module 66 comes into contact with water, the water can automatically move to all parts of the moisture storage module 66. For example, the moisture storage module 66 can be a sponge. Sponges are easy to absorb water, easy to conduct and release water, and inexpensive.

[0079] The air guide plate 50 has a water guiding module 58. The water guiding module 58 is made of a material that easily absorbs and releases water. When any part of the water guiding module 58 comes into contact with water, the water can automatically move to all parts of the water guiding module 58. For example, the water guiding module 58 can be a sponge.

[0080] The wall-mounted air conditioner indoor unit is configured such that when the outer guide plate 60 and the air guide plate 50 are rotated to an angle that allows the water guide module 58 to come into contact with the receiving portion 65, such that the water guide module 58 is adjacent to the moisture storage module 66 or water (e.g. Figure 12 and Figure 13 The water-guiding module 58 absorbs moisture, which is then dissipated into the indoor environment for humidification when the air guide plate 50 guides the airflow. The moisture is dispersed throughout the room with the airflow, resulting in better humidification. Furthermore, the wall-mounted air conditioner indoor unit of this embodiment can control the amount of humidification by adjusting the rotation speed of the air guide plate 50, demonstrating a very ingenious structure. In addition, users can add purifying or aromatherapy additives to the water, or directly use other liquids with purifying or aromatherapy functions to replace water, thereby achieving indoor environmental purification and aromatherapy functions.

[0081] In this embodiment of the invention, when the air guide plate 50 rotates to guide the airflow, the water in the water guiding module 58 is thrown into the indoor environment, completing the humidification of the indoor environment. This allows the water to be dispersed throughout the room with the airflow, resulting in better humidification. Furthermore, the air guide plate 50 rotates frequently during airflow and sometimes swings back and forth, making it unsuitable for storing large amounts of water. Therefore, if the water source is located on the air guide plate 50, the humidification time of the air guide plate 50 will be shorter. The main function of the outer guide plate 60 is to open and close the air outlet 12. After opening the air outlet 12, it does not need to rotate, and even if it does, the rotation is minimal. Therefore, it is suitable for storing more water for the air guide plate 50 to humidify, extending the humidification time of the air guide plate 50.

[0082] In some embodiments, such as Figure 14 As shown, each receiving portion 65 is located on the inner side 611 of the outer guide plate 60 facing the interior of the housing 10 when the air outlet 12 is closed. Each receiving portion 65 is a box body with its bottom connected to the inner side 611 and open in a direction away from the outer guide plate 60. One side of the box body is open, forming a groove, which is used to place the moisture storage module 66.

[0083] Furthermore, such as Figure 14 As shown, each receiving portion 65 can be an elongated strip extending along the length of the outer guide plate 60, with a triangular cross-section whose apex connects to the inner surface 611 of the outer guide plate 60. That is, the receiving portion 65 is an elongated triangular groove. Correspondingly, the moisture storage module 66 can be a triangular prism shape so that it fits snugly into the receiving portion 65. In this embodiment, each receiving portion 65 is configured with a relatively large opening to allow for better contact between water or the moisture storage module 66 and the water guiding module 58 of the air guide plate 50.

[0084] In some embodiments, such as Figure 14 As shown, the outer guide plate 60 includes a plate body 61 and a plurality of mounting arms 62 connected to the plate body 61. The plurality of mounting arms 62 are arranged along the length direction of the outer guide plate 60 for rotatable engagement with the housing 10. There are a plurality of receiving portions 65, with one receiving portion 65 provided between every two mounting arms 62, so that the receiving portion 65 avoids the mounting arms 62. For example... Figure 14 As shown, there are three mounting arms 62 and two receiving parts 65.

[0085] In some embodiments, such as Figure 15 As shown, at least a portion of the air guide plate 50 is hollow, forming an elongated moisture-guiding cavity 518 extending along its length direction x. For multi-layer air guide plates, only the outer plate 51 may have the elongated moisture-guiding cavity 518. At least one side surface of the air guide plate 50 has multiple moisture dissipation holes 510 communicating with the elongated moisture-guiding cavity 518, so that water in the receiving part 65 (including water in the moisture storage module 66) enters the elongated moisture-guiding cavity 518 through the multiple moisture dissipation holes 510. A water guiding module 58 is disposed within the elongated moisture-guiding cavity 518. The water guiding module 58 can guide the water injected into the elongated moisture-guiding cavity 518 to various points along the length of the elongated moisture-guiding cavity 518, making the moisture distribution more uniform.

[0086] In some embodiments of the present invention, such as Figure 15 As shown, the edge of the air guide plate 50 in the width direction has an opening 5181, which is also the opening of the elongated moisture-guiding cavity 518, allowing the water-guiding module 58 to be inserted into the elongated moisture-guiding cavity 518. In this way, when the user needs to replace or clean the water-guiding module 58, the water-guiding module 58 can be removed from the opening 5181.

[0087] In some embodiments of the present invention, multiple moisture dissipation holes 510 are provided on both sides of the air guide plate 50. In this way, both sides of the air guide plate 50 can absorb moisture, resulting in a greater water absorption capacity. They can also dissipate moisture, ensuring that moisture is always directed towards the indoor environment regardless of the angle to which the air guide plate 50 is rotated.

[0088] In some embodiments of the present invention, such as Figure 15 As shown, a water storage tank 516 connected to the elongated moisture-wicking cavity 518 can be installed on the air guide plate 50. Thus, the water in the water storage tank 516 constitutes the water source for the elongated moisture-wicking cavity 518. The specific source of the water can be added by the user or drawn from the condensate of the evaporator inside the air conditioner. Using the water storage tank 516 as a supplement, the water in it, together with the water in the outer guide plate 60, is used for humidification.

[0089] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
