Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to an air guide assembly and an air conditioning device. Background Technology

[0002] Some air conditioning devices need to achieve a certain airflow, but without a noticeable draft. Take sterilizers as an example: front-discharge sterilizers have a larger airflow and can deliver better sterilization results. However, the draft at the front of the sterilizer is quite noticeable, leading to a poor user experience. Summary of the Invention

[0003] The main objective of this invention is to provide an air guiding component and an air conditioning device, which aims to provide an air guiding component and an air conditioning device with less wind sensation and a comfortable user experience.

[0004] To achieve the above objectives, the present invention provides an air guiding assembly, comprising:

[0005] The mounting frame has a frame opening for connecting with the air outlet of the air conditioning unit; and,

[0006] An air guide is movably disposed on the mounting frame to have an open state where the frame opening is opened and a closed state where the frame opening is partially covered. In the closed state, the air guide causes the air outlet area of ​​the frame opening to decrease from top to bottom.

[0007] In one embodiment, the frame opening has an upper region and a lower region divided by height. When the air guide is in the closed state, the air outlet area of ​​the lower region is smaller than that of the upper region, and the ratio of the height of the upper region to the height of the lower region is greater than or equal to 0.9 and less than or equal to 1.1.

[0008] In one embodiment, the air guide includes multiple air guide blades arranged sequentially in the vertical direction. Each air guide blade is rotatably mounted on the mounting frame around a horizontally extending pivot. When the air guide is in the open state, each air guide blade rotates to extend in the horizontal direction. When the air guide is in the closed state, each air guide blade rotates to extend in the vertical direction.

[0009] In one embodiment, when the air guide is in the closed state, the area of ​​each air guide blade on the lower side of the rotating shaft is greater than the area on the upper side of the rotating shaft.

[0010] In one embodiment, when the air guide is in the closed state, at least a portion of the air guide blades have a notch recessed from the edge of the air guide blade toward the rotating shaft in the region above the rotating shaft.

[0011] In one embodiment, each of the notches is formed in the middle region of at least a portion of the guide vanes in the horizontal direction.

[0012] In one embodiment, the rotational stroke of each of the guide vanes is no greater than 90 degrees downward from the horizontal direction.

[0013] In one embodiment, the mounting frame is circular, with the frame opening formed in the middle of the circular frame, and the multiple guide vanes are rotatably connected to the inner circumference of the mounting frame at both ends in the horizontal direction.

[0014] In one embodiment, when the air guide is in the closed state, the lower edge of the lowest air guide vane is arranged in an arc shape corresponding to the inner circumference of the mounting frame.

[0015] In one embodiment, the air guide assembly further includes a connecting rod rotatably connected to each of the air guide vanes. The connecting rod extends in the vertical direction and is movably arranged in the vertical direction to drive each of the air guide vanes to rotate.

[0016] To achieve the above objectives, the present invention also provides an air conditioning device, comprising:

[0017] A housing having an air inlet, an air outlet, and an air duct connecting the air inlet and the air outlet; and,

[0018] The air guide assembly described above is disposed on the housing.

[0019] In one embodiment, the air conditioning device further includes an axial flow fan, each of the axial flow fans including a motor and axial flow blades, and the air inlet, the axial flow fan, the air outlet and the air guide assembly are arranged sequentially in the axial direction.

[0020] In one embodiment, the air guide assembly is the air guide assembly as described above, the motor is mounted on the middle of the air outlet via a motor mount, and in the open state, each of the notches of the air guide assembly avoids the mounting frame.

[0021] In one embodiment, there are two air outlets and two axial flow fans, with the two axial flow fans spaced apart in the vertical direction, and the two air outlets corresponding to the air outlet side of each axial flow fan.

[0022] In one embodiment, the air conditioning device is a sterilizer.

[0023] The air guide assembly provided by this invention includes a mounting frame and an air guide section. The frame has an opening for connecting with the air outlet of an air conditioning device. The air guide section is movably disposed on the mounting frame, allowing it to be in an open state (with the frame opening open) and a closed state (partially covering the frame opening). In the closed state, the area covered by the upper region of the air guide section is smaller than the area covered by the lower region. The ratio of the height of the upper region to the height of the lower region is greater than or equal to 0.3 and less than or equal to 3. In the open state, the air guide assembly provides a larger airflow to the air conditioning device. In the closed state, it causes the airflow velocity of the air conditioning device to increase from top to bottom. While ensuring a certain airflow volume, it significantly reduces the wind sensation in front of the air outlet, resulting in a more comfortable user experience for air conditioning devices such as sterilizers.

[0033] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0037] This invention provides an air conditioning device, which can be an air conditioner, air purifier, air cooler fan or sterilizer, etc., that has an air supply function and can regulate the air environment.

[0038] In this embodiment, please refer to Figures 1 to 3 The air conditioning device is a sterilizer 100, specifically a machine that disinfects the air through principles such as filtration, purification, and sterilization. The sterilizer 100 can utilize ozone, ultraviolet light, photocatalysis, and / or filters to purify and sterilize the air, resulting in clean surrounding air. Some sterilizers 100 can also actively purify the surrounding air by releasing disinfectant and sterilizing components into the air through airflow. Depending on its disinfection principle, it can kill one or more harmful components such as bacteria, viruses, mold, spores, formaldehyde, phenol, pollen, and other allergens. Simultaneously, it can effectively remove odors in the air, such as smoke and odors from cigarettes, unpleasant odors from restrooms, and body odor.

[0039] The large air volume of the sterilizer 100 can promote indoor air circulation and achieve better sterilization effect. However, if the airflow of the sterilizer 100 is too strong, it will bring a bad user experience to users around the sterilizer 100. Especially for the front-discharge sterilizer 100, when users pass in front of the sterilizer 100, they will feel the airflow of the sterilizer 100 and have a bad physiological or psychological feeling. Therefore, there is a need to provide a sterilizer 100 that can ensure airflow while reducing the feeling of airflow.

[0040] To achieve the above objectives, the present invention provides an air guide assembly 10 and an air conditioning device including the air guide assembly 10. It is understood that the air conditioning device is not limited to the sterilizer 100, but may also be an air conditioner, air purifier, air cooler fan, or other devices that require low-wind-feel airflow in certain situations. In this embodiment, the sterilizer 100 is used as an example for explanation.

[0041] Please see Figures 1 to 3 The sterilizer 100 includes a housing 20 and an air guide assembly 10. The housing 20 has an air inlet 21, an air outlet 22, and an air duct 23 connecting the air inlet 21 and the air outlet 22. The air guide assembly 10 is disposed on the housing 20 and is positioned corresponding to the air outlet 22. In this embodiment, the air guide assembly 10 is installed at the air outlet 22 to guide the airflow delivered from the air duct 23. In one embodiment, the housing 20 may also be provided with an air outlet grille 40 outside the air outlet 22 to make the sterilizer 100 more aesthetically pleasing and to disperse the airflow and reduce the feeling of draft.

[0042] It is understood that the air duct 23 is generally equipped with a fan assembly to drive airflow from the air inlet 21 into the air duct 23, and then out through the air outlet 22 after being guided by the air guide assembly 10. The type of fan assembly is not limited; for example, it can be an axial flow fan 30, a centrifugal fan, or a cross-flow fan, etc., and can be selected according to the specific shape and airflow direction of the sterilizer 100. To achieve the sterilization function, the air duct 23 can also be equipped with a purification device and / or a disinfectant release device, such as a pre-filter, a photocatalytic filter, an ultraviolet lamp, an ozone generator, a negative ion generator, or a disinfectant release device, so that harmful components in the air flowing through the air duct 23 are purified and then sent out through the air outlet 22, and / or, beneficial components with sterilization and disinfection functions, such as negative ions and disinfectants, are sent out through the air outlet 22.

[0043] In this embodiment, the fan assembly is an axial flow fan 30, each axial flow fan 30 including a motor 31 and an axial flow impeller 32. The air inlet 21, the axial flow fan 30, the air outlet 22, and the air guide assembly 10 are arranged sequentially in the axial direction. Preferably, the air outlet 22 is located at the front of the sterilizer 100, the air inlet is located at the rear of the sterilizer, the air duct 23 extends horizontally, and the axial flow fan 30 and the purification device and / or disinfectant release device are all located in the air duct 23, thus ensuring smooth airflow and a large air volume from the sterilizer 100. Preferably, the motor 31 is mounted in the middle of the air outlet 22 via a motor mounting base, the motor mount of the motor 31 is located in the motor mounting base, the motor axis of the motor 31 extends rearward and is drivenly connected to the axial flow impeller 32 behind it to drive the axial flow impeller 31 to rotate. In this way, the air supply of the axial flow fan 30 is less obstructed, resulting in more uniform airflow from the air outlet 22.

[0044] In this embodiment, please continue to refer to Figures 4 to 7 The air guide assembly 10 is used to guide the airflow delivered from the air outlet 22, and specifically includes a mounting frame 11 and an air guide section 12. The mounting frame 11 has a frame opening, which is used to connect with the air outlet 22 of the air conditioning device (in this embodiment, a sterilizer 100). The air guide section 12 is movably disposed on the mounting frame 11 to have an open state with the frame opening open and a closed state with the frame opening partially covered. In the closed state, the air guide section 12 causes the air outlet area of ​​the frame opening to decrease from top to bottom.

[0045] The mounting frame 11 can be integrally formed with the housing 20, or it can be detachably assembled with the housing 20. The mounting frame 11 is installed at the air outlet 22 and forms a frame opening that connects with the air outlet 22. It can be understood that the mounting frame 11 can be arranged in a complete circle or in segments. The shape of the frame opening is not limited, as long as it can connect with the air outlet 22 and deliver the airflow passing through the air duct 23. The structure, material, and movement mode of the air guide 12 are not limited. In this embodiment, the air guide 12 is movably provided on the mounting frame 11 to switch between the open state and the closed state. In the open state, the air guide 12 basically does not cover the frame opening, or only partially covers the frame opening. In the closed state, the air guide 12 partially covers the frame opening. That is, the area of ​​the frame opening covered by the air guide 12 in the open state is smaller than that in the closed state, so that the air volume of the air outlet 22 is greater in the open state than in the closed state.

[0046] Furthermore, in the closed state, the air guide 12 causes the air outlet area of ​​the frame opening to decrease from top to bottom. In this embodiment, this is achieved by the air guide 12 covering the frame opening. Specifically, the frame opening can be divided into an upper region and a lower region in terms of height. In one embodiment, the air guide 12 covers a smaller area or no area of ​​the upper region, while covering a larger area of ​​the lower region, making the air outlet area of ​​the upper region of the frame opening larger than that of the lower region. In another embodiment, the air guide 12 covers a smaller proportion of the upper region and a larger proportion of the lower region, making the air outlet area of ​​the upper region of the frame opening larger than that of the lower region.

[0047] The upper and lower regions of the frame opening are separated by a height boundary line. This boundary line can be the center line of the frame opening in terms of height, or it can be downwards or offset downwards by a certain distance from this center line. In this embodiment, the ratio of the height of the upper region to the height of the lower region is greater than or equal to 0.3 and less than or equal to 3. Thus, in the closed state, the air guide 12 causes the air outlet area of ​​the frame opening to decrease from top to bottom. In other words, in the closed state, the air guide assembly 10 causes the air supply of the sterilizer 100 to be affected by the air guide 12, and its wind speed also increases from top to bottom. That is, the air supply speed is high at higher locations and low at lower locations, resulting in a smaller wind feel at the feet and a less noticeable airflow, making the user feel comfortable. Especially for the floor-standing, front-discharge sterilizer 100, the air supply temperature is generally room temperature and the height is about 1 meter. At this time, if the air supply speed is distributed in a downward trend, the human body will hardly feel the wind while the sterilizer 100 is supplying air, making the user experience comfortable.

[0048] In one embodiment, the ratio of the height of the upper region to the height of the lower region is greater than or equal to 0.9 and less than or equal to 1.1. That is, the boundary between the upper and lower regions of the frame opening is approximately at half the height of the frame opening. This results in the frame opening being more partially covered in the upper region and less covered in the lower region. Consequently, the airflow from the air outlet 22 is also more obstructed in the upper region and less obstructed in the lower region, achieving a higher airflow velocity at higher points of the frame opening and a lower airflow velocity at lower points. This results in a less noticeable airflow sensation at the feet, leading to a more comfortable experience for the user.

[0049] There are several ways to achieve the effect that the proportion of the frame opening being covered increases from top to bottom when the air guide 12 is in the closed state. In one embodiment, this is achieved by the air guide 12 being in different states in the upper and lower regions when in the closed state. For example, the air guide 12 may include multiple air guide vanes 120 arranged sequentially in a vertical direction. In the closed state, the air guide vanes 120 in the upper region are in an open state that is approximately parallel to the air supply direction, while the air guide vanes 120 in the lower region are in a covered state that forms an angle with the air supply direction. However, this implementation requires the air guide vanes 120 in different regions to be driven by different driving methods, resulting in a relatively complex structure and higher production or maintenance costs.

[0050] In one embodiment, please refer to Figures 5 to 7 The air guide section 12 includes multiple air guide vanes 120 arranged sequentially in a vertical direction. Each air guide vane 120 is rotatably mounted on the mounting frame 11 around a horizontally extending pivot 121. When the air guide section 12 is in the open state, each air guide vane 120 rotates to extend horizontally. When the air guide section 12 is in the closed state, each air guide vane 120 rotates to extend vertically. It should be noted that the directional descriptions in this invention only apply to the orientation of the air conditioning device in normal use, and do not include the orientation of the air conditioning device in production, assembly, transportation, etc. "Horizontal" refers to being approximately parallel to the horizontal plane, and may have an angle with the horizontal plane within a certain range. "Vertical" refers to being approximately parallel to the direction of gravity, and may also have an angle with the direction of gravity within a certain range. In this embodiment, the air outlet 22 faces forward. When the guide vane 120 rotates to the horizontal direction, the area of ​​the air outlet 22 that is blocked is minimized, thereby opening the air outlet 22 and increasing the air volume, which is suitable for the air supply needs of the sterilizer 100 in its high-efficiency working state. When the guide vane 120 rotates to the vertical direction, the air outlet 22 is partially blocked, resulting in the air outlet 22 being blocked in an increasing trend from top to bottom, achieving low-wind-feel airflow and making the human body feel comfortable.

[0051] Further, please refer to Figure 7 , Figure 7The diagram shows a front view of the air guide section 12 in its closed state. As can be seen, each of the air guide vanes 120 rotates around a horizontally extending shaft 121. When the air guide section 12 is closed, the area of ​​each air guide vane 120 on the lower side of the shaft 121 is larger than its area on the upper side. This results in a larger exposed area at the upper part of the air outlet 22 than at the lower part when each air guide vane 120 covers the frame opening. This achieves a higher air velocity at higher elevations and a lower air velocity at lower elevations, resulting in a less noticeable airflow around the feet and a more comfortable experience for the user. Thus, the upper area of ​​each of the guide vanes 120 is smaller, resulting in less obstruction of the air outlet 22, while the lower area is larger, resulting in greater obstruction of the air outlet 22. The degree of obstruction of the entire air outlet 22 is distributed in an alternating pattern of small, large, and large. This ensures that the air velocity delivered by the air outlet 22 is smaller at the top and larger at the bottom in the vertical direction, while maintaining a relatively uniform air velocity distribution, rather than a sudden decrease from top to bottom. This ensures uniform air delivery while providing a lower airflow feel and a comfortable user experience.

[0052] For more information, please continue reading. Figure 7 When the air guide section 12 is in the closed state, at least a portion of each of the air guide blades 120 has a notch 122 recessed from the edge of the air guide blade 120 towards the rotating shaft 121 in the region above the rotating shaft 121. Thus, the notch 122 of each air guide blade 120 results in a smaller upper area, less obstruction of the air outlet 22, and a larger lower area, greater obstruction of the air outlet 22. The structure is simple, the cost is low, and the blade shapes of each air guide blade are relatively similar, making it easy to manufacture.

[0053] In one embodiment, each of the notches 122 is formed in the middle region of at least a portion of the guide vanes 120 in the horizontal direction. Corresponding to the sterilizer 100 equipped with the axial flow fan 30, the air velocity at the center of the air outlet 22 is generally slightly lower than the outer periphery air velocity. The notches 122 are positioned in the middle of the air outlet 22, resulting in more uniform air distribution, lower noise, and a more comfortable airflow. Simultaneously, when the guide vanes 120 rotate to extend horizontally, the notches 122 can also correspondingly avoid the motor 31 seat located in the middle of the air outlet 22, resulting in a reasonable and compact structure that allows the sterilizer 100 to be smaller in size and occupy less space.

[0054] Preferably, the rotational stroke of each of the guide vanes 120 is no greater than 90 degrees downward from the horizontal direction. This ensures that the stroke of each guide vane is limited to within 90 degrees, eliminating the need for a 180-degree rotation. Consequently, the area and / or shape differences on both sides of the pivot 121 can be made larger without worrying about obstruction or blockage between adjacent guide vanes 120 or between the guide vane 120 and the mounting frame 11 during the rotational stroke.

[0055] This embodiment can be implemented in conjunction with the previous embodiment. When the air outlet 22 is provided with components such as a motor mounting base, when the air guide 12 is in the open state, the notch 122 of the air guide vane 120 can correspondingly avoid the motor mounting base, so that the size of the air conditioning device in the front-back direction can be smaller and the structure is more compact.

[0056] Please see Figure 7 In one embodiment, the mounting frame 11 is circular, with the frame opening formed in the middle. Multiple guide vanes 120 are rotatably connected to the inner circumference of the mounting frame 11 at both ends in the horizontal direction. In this embodiment, the circular mounting frame 11 is suitable for the air delivery method of the axial flow fan 30 and also makes the sterilizer 100 aesthetically pleasing.

[0057] Based on the previous embodiment, when the air guide section 12 is in the closed state, the lower edge of the lowermost air guide vane 120 is arc-shaped, corresponding to the inner circumference of the mounting frame 11. This ensures that when the air guide section 12 is closed, the shape of the lowermost air guide vane 120 fits snugly against the circular shape of the frame opening, better blocking the airflow from the lower end of the air outlet 22, achieving a gradually decreasing wind speed distribution from top to bottom, resulting in a superior airflow experience.

[0058] There are various ways to drive the guide vanes 120 to rotate. In this embodiment, please refer to [the relevant documentation]. Figure 5 and Figure 6 The air guide assembly 10 further includes a connecting rod 13 rotatably connected to each of the air guide vanes 120. The connecting rod 13 extends vertically and is movably arranged in the vertical direction to drive each of the air guide vanes 120 to rotate. In this embodiment, the air guide vanes 120 are driven to rotate synchronously by the vertically movable connecting rod 13, resulting in a simple and reliable structure with low production costs. The manner in which the connecting rod 13 is driven vertically is not limited, but preferably the connecting rod 13 is movably arranged in the mounting frame 11 and driven to move vertically by a motor located inside the housing 20.

[0059] In one embodiment, please refer to Figure 4The air outlet 22 and the axial flow fan 30 are provided in twos, the two axial flow fans 30 are arranged at intervals in the vertical direction, and the two air outlets 22 are respectively arranged on the air outlet side of each axial flow fan 30. Thus, two air outlets 22 are spaced vertically, resulting in a larger air volume output from the sterilizer 100. Furthermore, the air guide assembly 10 distributes the airflow in front of the sterilizer 100 into three vertical regions. The upper region corresponds to the upper area of ​​the upper air outlet 22, where the air outlet 22 is least obstructed, resulting in the highest airflow velocity. The middle region corresponds to the lower area of ​​the upper air outlet 22 and the upper area of ​​the lower air outlet 22, where the air outlet 22 is moderately obstructed, and the airflow velocity is moderate due to the mutual influence of the airflow fields from the two axial flow fans 30. The lower region corresponds to the lower area of ​​the lower air outlet 22, where the air outlet 22 is most obstructed, resulting in the lowest airflow velocity. Thus, the overall airflow speed in front of the sterilizer 100 also exhibits a top-to-bottom increasing trend, meaning the airflow speed is higher at higher locations and lower at lower locations. This results in a less noticeable airflow around the user's feet, making the experience comfortable. When the sterilizer 100 requires high-speed airflow to enhance the sterilization effect, the air guide 12 moves to the open position, opening both air outlets 22. At this point, the airflow volume is maximized, and the sterilization effect is optimal. Conversely, when the sterilizer 100 only requires a certain airflow volume and a noticeable airflow is undesirable to the user, the air guide 12 moves to the closed position, adjusting the airflow of the sterilizer 100 to create a layered airflow distribution that gradually decreases from top to bottom, resulting in a less noticeable airflow and a more comfortable user experience.

All equivalent structural transformations made under the inventive concept of the present invention using the contents of the accompanying drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
