Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air guide component and a mobile air conditioner. Background Art

[0002] Portable air conditioners are becoming increasingly popular in the market due to their portability. However, existing portable air conditioners can only deliver air in a single direction and angle, failing to deliver air in multiple directions and angles, resulting in a poor user experience. Utility Model Content

[0003] The first purpose of the present invention is to provide an air guide assembly to solve the technical problem that the existing mobile air conditioner can only supply air in a directional manner and cannot achieve multi-directional and multi-angle air supply.

[0004] The utility model provides an air guide assembly, including an air outlet panel, an air guide wheel and a stop member, the air outlet panel includes a panel body with an air supply port and a rotating shaft located at the air supply port, the air guide wheel is rotatably sleeved on the rotating shaft and opposite to the air supply port; the stop member is movably mounted on the rotating shaft, and the stop member and the panel body are separately arranged on both sides of the air guide wheel, wherein the air guide wheel has a first end face facing the stop member and a second end face opposite to the first end face, and the stop member has a stop position in contact with the first end face and a free rotation position spaced apart from the first end face.

[0005] Taking the application of the air guide assembly in a mobile air conditioner as an example, the air guide assembly can be installed on the front side of the mobile air conditioner when in use. When the mobile air conditioner needs to deliver concentrated air at a high wind speed, the stopper can be switched to a stop position in contact with the first end face, and the stopper can be tightly abutted against the first end face, so that the friction between the stopper and the first end face is much greater than the rotational force of the air flow driving the air guide wheel to rotate, thereby limiting the rotation of the air guide wheel. At this time, the air guide wheel is stationary, and the air flow is directly delivered through the air guide wheel, with a high wind speed and concentrated air flow. When the mobile air conditioner needs to deliver air in multiple directions and angles, the stopper can be switched to a free rotation position spaced from the first end face. At this time, the stopper's rotation-restricting effect on the air guide wheel is released, and the air guide wheel can rotate rapidly under the action of the driving air flow, thereby increasing the air supply angle and making the delivered air softer.

[0006] During the above process, when it is necessary to change the air supply speed of the mobile air conditioner, the stopper can be loosened appropriately, but not completely. At this time, the stopper still maintains contact with the first end face, but the friction between the stopper and the first end face is less than the rotational force of the air flow driving the air guide wheel to rotate, so that the air guide wheel can rotate slowly. Compared with the working state when the stopper is in the free rotation position, its rotation speed, air supply angle and air supply softness are all smaller, thereby achieving the purpose of changing the wind speed and air supply angle.

[0007] It can be seen that the air guide component can not only realize multi-directional and multi-angle air supply through the above-mentioned setting, but also can change the air supply speed and air supply angle according to needs, with good flexibility of use, thereby effectively improving the user experience.

[0008] Furthermore, the rotating shaft includes a pivoting section and a threaded section arranged axially, and the anti-rotation member includes a connecting column and an anti-rotation wall, wherein the air guide wheel is sleeved on the pivoting section; the connecting column has a threaded hole that is screwed together with the threaded section, and the anti-rotation wall is used to contact the first end surface at the anti-rotation position. This method of connecting the anti-rotation member to the rotating shaft allows that when the air guide assembly needs to be cleaned, the anti-rotation member can be first removed from the threaded section, and then the air guide wheel can be removed from the pivoting section, so that the air guide wheel can be wiped and cleaned in an open space. This disassembly process does not require specialized tools or disassembly of the air outlet panel, making it simple to operate and highly efficient to maintain.

[0009] Furthermore, the anti-rotation wall is an annular wall, and the anti-rotation wall surrounds the connecting column along the circumference of the connecting column. This allows the anti-rotation force acting on the wind wheel to be applied to various positions along the circumference of the wind wheel when the anti-rotation member is in the anti-rotation position, thereby ensuring the uniformity of force on the wind wheel and avoiding uneven local force on the wind wheel. And / or, the rotating shaft is provided with a limiting step, and the limiting step is located between the pivot section and the threaded section, and the limiting step is used to abut and cooperate with the end face of the connecting column to limit the maximum stroke of the anti-rotation member to the anti-rotation position. This setting allows the limiting step to abut and cooperate with the end face of the connecting column when the anti-rotation member moves further toward the direction of the wind wheel, thereby preventing the anti-rotation member from being over-twisted and damaging the wind wheel, thereby playing a certain protective role for the wind wheel.

[0010] Furthermore, the rotating shaft further comprises an annular boss disposed at an end of the pivoting section facing away from the threaded section, the wind guide wheel being provided with a limiting groove, the limiting groove abutting and cooperating with the annular boss along the axial direction of the wind guide wheel; and / or the rotating shaft is a hollow shaft. The provision of the annular boss can, on the one hand, provide an axial limit for the wind guide wheel, and, on the other hand, serve as a structural reinforcement between the rotating shaft and the panel body, thereby reducing the risk of fracture of the rotating shaft at the connection with the panel body.

[0011] Furthermore, the air guide assembly further includes an E-shaped retaining ring, the pivoting section being provided with a slot, the E-shaped retaining ring being detachably mounted in the slot, and the E-shaped retaining ring and the panel body being provided on either side of the air guide wheel. The E-shaped retaining ring is used to limit the movement of the air guide wheel toward the stop member in the free rotation position. This arrangement allows the E-shaped retaining ring to axially limit the air guide wheel during free rotation, preventing the air guide wheel from moving to the right and avoiding wear between the air guide wheel and the stop member caused by axial limiting by the stop member, thereby providing a certain degree of protection for both the air guide wheel and the stop member.

[0012] Furthermore, when the retaining groove and the annular boss are in contact, the distance between the E-shaped retaining ring and the first end face is s, where 0.3 mm ≤ s ≤ 0.5 mm. This arrangement allows for a gap between the E-shaped retaining ring and the air guide wheel, preventing the air guide wheel from becoming unable to rotate due to the E-shaped retaining ring being too tightly assembled with the air guide wheel along its axial direction.

[0013] Furthermore, the guide wheel includes an air guide ring and a plurality of air guide blades. The plurality of air guide blades are arranged radially from the center of the guide wheel and are inclined in the direction of the driving airflow from the center of the guide wheel toward the air guide ring. This arrangement allows the driving airflow to directly act on the air guide blades after being blown out, which is more conducive to air guidance. Therefore, when the mobile air conditioner is in operation, only a small amount of air is required to drive the guide wheel to rotate.

[0014] Furthermore, the air outlet is provided with a plurality of supporting ribs, which fixedly connect the rotating shaft and the panel body. The provision of the supporting ribs can, on the one hand, provide structural reinforcement for the air outlet to prevent deformation of the air outlet, and on the other hand, support the rotating shaft to ensure the installation stability of the air guide wheel.

[0015] Furthermore, along the axial direction of the guide wheel, the guide wheel is at least partially embedded in the air outlet, the diameter of the guide wheel is d1, and the inner diameter of the air outlet is D1, wherein 1mm≤D1-d1≤3mm. By limiting the inner diameters of the guide wheel and the air outlet to the above range, on the one hand, it is possible to avoid interference with the air outlet panel during the rotation of the guide wheel due to a small difference between the diameter of the guide wheel and the inner diameter of the air outlet. On the other hand, it is possible to avoid a large gap between the outer periphery of the guide wheel and the air outlet panel due to a large difference between the diameter of the guide wheel and the inner diameter of the air outlet. And / or, the diameter of the axial hole of the guide wheel for fitting with the pivot section is D2, and the axial diameter of the pivot section is d2, wherein 0.3mm≤D2-d2≤0.6mm. By limiting the diameter of the shaft hole of the air guide wheel and the diameter of the pivot section within the above range, on the one hand, it is possible to avoid poor rotation due to over-tight assembly of the air guide wheel, and on the other hand, it is possible to avoid large shaking due to over-loose assembly of the air guide wheel.

[0016] The second purpose of the present invention is to provide a mobile air conditioner to solve the technical problem that the existing mobile air conditioners can only supply air in a directional manner and cannot achieve multi-directional and multi-angle air supply.

[0017] The mobile air conditioner provided by the utility model includes a casing, centrifugal fan blades and the above-mentioned air guide assembly, the casing is provided with a front opening, the centrifugal fan blades are installed inside the casing, the centrifugal fan blades are used to provide a driving airflow to the front opening, and the air guide assembly is installed in the casing and covers the front opening.

[0018] During use of the mobile air conditioner, the driving airflow provided by the centrifugal fan blades is sent out from the front opening of the casing to act on the air guide component installed at the front opening, thereby supplying air through the air guide component.

[0019] By arranging the above-mentioned air guide assembly in the mobile air conditioner, the mobile air conditioner accordingly has all the advantages of the above-mentioned air guide assembly, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Figure 1 A schematic diagram of the structure of a mobile air conditioner provided in this embodiment; Figure 2 This is a schematic diagram of the main view of the mobile air conditioner provided in this embodiment. Figure 1 and Figure 2 As shown, this embodiment provides a mobile air conditioner, including a casing 020, a centrifugal fan blade 030 and an air guide assembly 010, wherein the casing 020 is provided with a front opening, the centrifugal fan blade 030 is installed inside the casing 020, the centrifugal fan blade 030 is used to provide a driving airflow to the front opening, and the air guide assembly 010 is installed on the casing 020 and covers the front opening.

[0040] During use of the mobile air conditioner, the driving airflow provided by the centrifugal fan blades 030 is sent out from the front opening of the casing 020 to act on the air guide component 010 installed at the front opening, thereby supplying air through the air guide component 010.

[0041] In the following text, the specific structure and working principle of the air guide component 010 will be described in detail.

[0042] Figure 3 This is an exploded view of the structure of the air guide assembly 010 provided in this embodiment; Figure 4 A longitudinal structural cross-sectional view of the air guide assembly 010 provided in this embodiment; Figure 5 for Figure 4 A magnified view of the local structure at point A.

[0043] like Figures 3 to 5 As shown, the air guide assembly 010 provided in this embodiment includes an air outlet panel 100, an air guide wheel 200 and a stop member 300. Specifically, the air outlet panel 100 includes a panel body 120 with an air supply port 110 and a rotating shaft 130 located at the air supply port 110. The air guide wheel 200 is rotatably mounted on the rotating shaft 130 and is opposite to the air supply port 110. The stop member 300 is movably mounted on the rotating shaft 130, and the stop member 300 and the panel body 120 are respectively arranged on both sides of the air guide wheel 200, wherein the air guide wheel 200 has a first end face 210 facing the stop member 300 and a second end face 220 opposite to the first end face 210. The stop member 300 has a stop position in contact with the first end face 210 and a free rotation position spaced apart from the first end face 210.

[0044] When in use, the air guide assembly 010 can be installed on the front side of the mobile air conditioner. Figure 6 The mobile air conditioner provided in this embodiment is in the air supply schematic diagram when the rotation stop member 300 is in the rotation stop position, as shown in FIG. Figure 6 As shown, when the mobile air conditioner needs to deliver concentrated air at a high wind speed, the stopper 300 can be switched to the stop position in contact with the first end surface 210, and the stopper 300 is tightly abutted against the first end surface 210, so that the friction between the stopper 300 and the first end surface 210 is much greater than the rotational force of the air flow driving the air guide wheel 200 to rotate, thereby limiting the rotation of the air guide wheel 200. At this time, the air guide wheel 200 is stationary, and the air flow is directly delivered through the air guide wheel 200, with a high wind speed and concentrated air flow. Figure 7 The air supply diagram of the mobile air conditioner provided in this embodiment when the anti-rotation member 300 is in the free rotation position is as shown in FIG. Figure 7 As shown, when the mobile air conditioner needs to be used for multi-directional and multi-angle air supply, the stop member 300 can be switched to a free rotation position separated from the first end face 210. At this time, the rotation restriction effect of the stop member 300 on the guide wheel 200 is released, and the guide wheel 200 can rotate rapidly under the action of the driving airflow to increase the air supply angle and, at the same time, make the delivered air softer.

[0045] During the above process, when it is necessary to change the air supply speed of the mobile air conditioner, the stop member 300 can be loosened appropriately, and not completely. At this time, the stop member 300 still maintains contact with the first end face 210, but the friction between the stop member 300 and the first end face 210 is less than the rotational force of the air flow driving the guide wheel 200 to rotate, so that the guide wheel 200 can rotate slowly. Compared with the working state when the stop member 300 is in the free rotation position, its rotation speed, air supply angle and air supply softness are all smaller, thereby achieving the purpose of changing the wind speed and air supply angle.

[0046] It can be seen that the air guide component 010 can not only realize multi-directional and multi-angle air supply through the above-mentioned setting, but also can change the air supply speed and air supply angle according to needs, with good flexibility of use, thereby effectively improving the user experience.

[0047] Please continue to refer to Figure 5 In this embodiment, the rotating shaft 130 may include a pivot section 135 and a threaded section 131 arranged along the axial direction, and the stop member 300 includes a connecting column 310 and a stop wall 320, wherein the guide wheel 200 is sleeved on the pivot section 135; the connecting column 310 is provided with a threaded hole 311 that is spirally matched with the threaded section 131, and the stop wall 320 is used to contact the first end face 210 in the stop position.

[0048] When it is necessary to switch the stop member 300 between the stop position and the free rotation position, it is only necessary to screw the stop member 300, and use the spiral cooperation between the threaded hole 311 of the connecting column 310 of the stop member 300 and the threaded segment 131 of the rotating shaft 130 to convert the rotational motion into a linear feed of the stop member 300, so that the stop member 300 can be moved closer to or away from the first end face 210, so as to achieve the purpose of switching the stop member 300 between the stop position and the free rotation position.

[0049] In addition, this method of connecting the stop member 300 to the rotating shaft 130 also allows for the stop member 300 to be removed from the threaded section 131 when the air guide assembly 010 needs to be cleaned, and then the air guide wheel 200 can be removed from the pivot section 135 so that the air guide wheel 200 can be wiped and cleaned in an open space. The disassembly process does not require professional tools, nor does it require the removal of the air outlet panel 100. The operation is simple and the maintenance efficiency is high.

[0050] Figure 8 This is a structural diagram of the anti-rotation member 300 of the air guide assembly 010 provided in this embodiment. Figure 3 and Figure 5 , and combined with Figure 8 In this embodiment, the rotation-stopping wall 320 may be an annular wall, wherein the rotation-stopping wall 320 surrounds the connecting column 310 along the circumference of the connecting column 310 .

[0051] By setting the anti-rotation wall 320 as a full-circle annular wall structure, when the anti-rotation member 300 is in the anti-rotation position, the anti-rotation force acting on the guide wheel 200 is applied to various positions of the guide wheel 200 along the circumference, ensuring the uniformity of the force on the guide wheel 200 and avoiding local uneven force on the guide wheel 200.

[0052] Please continue to refer to Figure 5 In this embodiment, the rotating shaft 130 is provided with a limiting step 132. Specifically, the limiting step 132 is located between the pivot section 135 and the threaded section 131. The limiting step 132 is used to abut and cooperate with the end face of the connecting column 310 to limit the maximum stroke of the stop member 300 moving to the stop position.

[0053] When the stop member 300 is rotated from the free rotation position to the stopped position, the stop wall 320 tightly contacts the air guide wheel 200 to limit the rotation of the air guide wheel 200, indicating that the stop member 300 has moved into position. By providing the aforementioned limiting step 132, as the stop member 300 moves further toward the air guide wheel 200, the limiting step 132 will contact and cooperate with the end surface of the connecting column 310, preventing the stop member 300 from being over-twisted and damaging the air guide wheel 200, thereby providing a certain degree of protection for the air guide wheel 200.

[0054] Figure 9This is a structural diagram of the E-shaped retaining ring 400 of the air guide assembly 010 provided in this embodiment. Figure 3 and Figure 5 , and combined with Figure 9 In this embodiment, the air guide assembly 010 may further include an E-type retaining ring 400, wherein the pivot section 135 is provided with a card slot 134, and the E-type retaining ring 400 is detachably installed in the above-mentioned card slot 134, and the E-type retaining ring 400 and the panel body 120 are respectively arranged on both sides of the air guide wheel 200, and the E-type retaining ring 400 is used to limit the movement stroke of the air guide wheel 200 toward the stop member 300 in the free rotation position.

[0055] The arrangement of the E-shaped retaining ring 400 allows the stopper 300 to be screwed to the right side of the E-shaped retaining ring 400 ( Figure 5 As shown in the perspective, during the free rotation of the guide wheel 200, the E-type retaining ring 400 axially limits the guide wheel 200 on the right side to prevent the guide wheel 200 from moving to the right, and avoids the wear of the guide wheel 200 and the stop member 300 caused by the axial limitation of the stop member 300, thereby playing a certain protective role for the guide wheel 200 and the stop member 300.

[0056] Please continue to refer to Figure 5 In this embodiment, when the limiting groove 250 and the annular boss 133 are in contact with each other, the distance between the E-type retaining ring 400 and the first end face 210 is s, where 0.3 mm ≤ s ≤ 0.5 mm.

[0057] It should be noted that the first end surface 210 of the air guide wheel 200 refers to the surface thereof facing the rotation stop 300, and can be a flat surface or an uneven surface as shown in this embodiment. The distance between the E-shaped retaining ring 400 and the first end surface 210 is the distance between the E-shaped retaining ring 400 and the air guide wheel 200 along the axial direction of the air guide wheel 200. Similarly, the second end surface 220 of the air guide wheel 200 refers to the surface thereof facing the panel body 120, and can be a flat surface or an uneven surface as shown in this embodiment.

[0058] This arrangement leaves a gap between the E-shaped retaining ring 400 and the air guide wheel 200, thereby preventing the air guide wheel 200 from being unable to rotate due to the E-shaped retaining ring 400 being too tightly assembled with the air guide wheel 200 along the axial direction of the air guide wheel 200.

[0059] Figure 10 This is a schematic diagram of the structure of the wind guide wheel 200 of the wind guide assembly 010 provided in this embodiment. Figure 2 and Figure 3 , and combined with Figure 10In this embodiment, the guide wheel 200 may include an air guide ring 230 and a plurality of air guide blades 240. Specifically, the plurality of air guide blades 240 are arranged radially from the center of the guide wheel 200 toward the air guide ring 230. The plurality of air guide blades 240 are inclined toward the direction of the driving airflow. Figure 2 The solid arrow on the middle wind guide wheel 200 is used to indicate this.

[0060] By setting the multiple guide blades 240 of the guide wheel 200 to be inclined in the direction of the driving airflow, the driving airflow can directly act on the guide blades 240 after being blown out, which is more conducive to air guidance. Therefore, when the mobile air conditioner is running, only a small amount of air is needed to drive the guide wheel 200 to rotate.

[0061] Figure 11 This is a structural diagram of the air outlet panel 100 of the air guide assembly 010 provided in this embodiment. Figure 3 , and combined with Figure 11 In this embodiment, the air outlet 110 is provided with a plurality of supporting ribs 140 , wherein the plurality of supporting ribs 140 are fixedly connected to the rotating shaft 130 and the panel body 120 .

[0062] The arrangement of the supporting ribs 140 can, on the one hand, reinforce the structure of the air outlet 110 to suppress deformation of the air outlet 110 , and on the other hand, support the rotating shaft 130 to ensure the installation stability of the air guide wheel 200 .

[0063] Specifically, in this embodiment, there are four support ribs 140 arranged in a cross shape. This arrangement not only ensures the structural stability of the air outlet 110 and the stability of the support for the rotating shaft 130, but also reduces obstruction of the air outlet 110, thereby ensuring the air supply volume.

[0064] Please continue to refer to Figure 5 and Figure 11 In this embodiment, the rotating shaft 130 may further include an annular boss 133, wherein the annular boss 133 is arranged at the end of the pivot section 135 away from the threaded section 131, and the air guide wheel 200 is provided with a limiting groove 250, and along the axial direction of the air guide wheel 200, the limiting groove 250 abuts and cooperates with the annular boss 133.

[0065] The annular boss 133 is provided on the left side of the guide wheel 200 ( Figure 5 On the other hand, it can also play a structural reinforcement role between the rotating shaft 130 and the panel body 120 to reduce the risk of fracture of the rotating shaft 130 at the connection between the rotating shaft 130 and the panel body 120.

[0066] Please continue to refer to Figure 5 In this embodiment, the rotating shaft 130 is a hollow shaft.

[0067] By configuring the rotating shaft 130 as a hollow shaft, not only the structural strength of the rotating shaft 130 can be ensured, but also materials can be saved.

[0068] Please continue to refer to Figure 4 In this embodiment, the air guide wheel 200 is partially embedded in the air outlet 110 along the axial direction of the air guide wheel 200, wherein the diameter of the air guide wheel 200 is d1, the inner diameter of the air outlet 110 is D1, and 1mm≤D1-d1≤3mm.

[0069] By limiting the inner diameters of the guide wheel 200 and the air outlet 110 within the above-mentioned range, on the one hand, it is possible to avoid interference between the guide wheel 200 and the air outlet panel 100 during rotation due to the small difference between the diameter of the guide wheel 200 and the inner diameter of the air outlet 110; on the other hand, it is also possible to avoid a large gap between the outer periphery of the guide wheel 200 and the air outlet panel 100 due to the large difference between the diameter of the guide wheel 200 and the inner diameter of the air outlet 110.

[0070] Preferably, D1-d1=2 mm.

[0071] Please continue to refer to Figure 5 In this embodiment, the diameter of the shaft hole of the guide wheel 200 for fitting with the pivot section 135 is D2, and the shaft diameter of the pivot section 135 is d2, wherein 0.3mm≤D2-d2≤0.6mm.

[0072] By limiting the diameter of the shaft hole of the guide wheel 200 and the diameter of the pivot section 135 within the above range, on the one hand, it is possible to avoid poor rotation due to over-tightening of the guide wheel 200, and on the other hand, it is possible to avoid large shaking due to over-loosening of the guide wheel 200.
