[0006] Furthermore, along the radial direction of the volute tongue body, a portion of the guide wheel protrudes from the volute tongue body to support the volute tongue body and maintain a gap between the volute tongue body and the volute casing components.

[0007] Furthermore, the rotation axis of the guide wheel is parallel to the rotation axis of the worm tongue body, and the worm tongue body is provided with a clearance groove for avoiding the wheel body.

[0008] Furthermore, the guide wheel includes a wheel body and a wheel axle connected to the wheel body. One end of the wheel axle is fixedly connected to the wheel body, and the other end of the wheel axle is rotatably connected to the worm tongue body. A mounting groove for mounting the wheel axle is provided on one side of the clearance groove.

[0009] Furthermore, the mounting groove includes a rotating groove section and a snap-fit ​​groove section that are interconnected. The rotating groove section is used to mount the axle so that the axle can rotate, and the snap-fit ​​groove section is used to allow the axle to snap into the rotating groove section. At least part of the rotating groove section is an arc-shaped groove, and the groove sidewall of the rotating groove section is clearance-fitted with the outer diameter of the axle. The snap-fit ​​groove section is a rectangular groove, and the groove width of the snap-fit ​​groove section is smaller than the outer diameter of the axle.

[0010] Furthermore, axles are provided at both ends of the wheel body, and the wheel body and the two axles are integrally formed. Two mounting grooves for mounting the two axles are provided on opposite sides of the clearance groove.

[0011] Furthermore, there are multiple guide wheels, which are arranged at intervals along the axial direction of the volute body at the end of the volute body away from the pressurization start end.

[0012] According to a second aspect of the present invention, a fan device is provided, comprising a volute component and a volute tongue component, wherein the volute tongue component is the aforementioned volute tongue component.

[0013] Furthermore, the volute component includes a first volute portion and a second volute portion disposed opposite to each other along the rotation axis of the fan blade located within the volute component. Both the end of the first volute portion opposite to the volute tongue body and the end of the second volute portion opposite to the volute tongue body are provided with a pointed corner structure.

[0014] Furthermore, the volute component is provided with a first windbreak and a second windbreak, which are arranged opposite to each other to form a cavity for mounting the volute tongue component and a first air guide channel and a second air guide channel communicating with the cavity; the first air guide channel and the second air guide channel are centrally symmetrical about the rotation axis of the volute tongue body; wherein, the first windbreak and the second windbreak each include a cavity baffle and a first air guide plate and a second air guide plate provided at both ends of the cavity baffle; the first air guide plate is tangent to the cavity baffle; the second air guide plate intersects the cavity baffle to form a sharp corner structure.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 13 As shown, the present invention provides a volute tongue component, comprising: a volute tongue body 11, which is rotatably disposed within a volute housing component 2 about a predetermined axis, and a pressurization initiation end 110 is provided on the volute tongue body 11; a guide wheel 12, which is disposed on the volute tongue body 11 and located at one end of the volute tongue body 11 away from the pressurization initiation end 110; along the direction surrounding the predetermined axis, a portion of the wheel body 121 of the guide wheel 12 protrudes from the volute tongue body 11, and when the volute tongue body 11 moves along the predetermined direction to a predetermined position of the volute housing component 2, the wheel body 121 contacts the sharp corner structure 2000 before the volute tongue body 11 contacts the sharp corner structure 2000 of the volute housing component 2, so as to guide the volute tongue body 11.

[0035] The volute tongue component of the present invention has a guide wheel 12 installed at the end of the volute tongue body 11 away from the pressurization initiation end 110. When the volute tongue body 11 moves in a predetermined direction towards a predetermined position of the volute housing component 2, the wheel body 121 of the guide wheel 12 contacts the sharp corner structure 2000 of the volute housing component 2 before the volute tongue body 11 contacts the sharp corner structure 2000 of the volute housing component 2, so as to guide and correct the volute tongue body 11. In this way, the guide wheel 12 can not only prevent the volute tongue component from interfering and jamming with the volute housing component 2 when the deformation of the volute tongue component is too large, thus affecting the movement of the volute tongue component, but also can support the end of the volute tongue component when the deformation of the volute tongue component is small, avoiding abnormal noise caused by the volute tongue component rubbing against the inner wall of the volute housing component 2. This solves the problem in the prior art that the movable volute tongue in the fan is easily deformed, affecting the normal operation of the volute tongue.

[0036] Specifically, the predetermined direction is Figure 11 The F direction is indicated by the middle arrow.

[0037] when Figure 5 When the volute component at the indicated position is to achieve the upward air outlet function, the volute component will rotate in the F direction. If the end of the volute component away from the pressurization initiation end 110 deforms and protrudes outward, when the volute component rotates to... Figure 11 and Figure 12 When the volute tongue component is at the correct position, it will interfere with the volute housing component 2. If the volute tongue component continues to move, it will be jammed by the sharp corner structure 2000 of the volute housing component 2. However, by setting a guide wheel 12 at the end of the volute tongue component away from the boosting start end 110, the guide wheel 12 will contact the volute housing component 2 earlier than the volute tongue component. The guide wheel 12 is subjected to the forward force of the volute tongue component and the oblique upward force of the volute housing component 2, and will continue to move, taking the tail end of the volute tongue component upward, so as to correct the shape of the volute tongue component, so that the deformed volute tongue component can continue to rotate smoothly in the F direction, and finally reach the desired position. Figure 8 At the designated location shown.

[0038] like Figure 7 and Figure 9 As shown, along the radial direction of the volute tongue body 11, a portion of the wheel body 121 of the guide wheel 12 protrudes from the volute tongue body 11 to support the volute tongue body 11 and maintain a gap between the volute tongue body 11 and the volute housing component 2.

[0039] Specifically, when the end of the volute tongue component away from the pressurization initiation end 110 deforms and protrudes outward, the volute tongue component will rub against the inner wall of the volute housing component 2. As the volute tongue component rotates within the volute housing component 2, it will continuously rub against the inner wall, thus producing abnormal noise. By providing a guide wheel 12 at the end of the volute tongue body 11 away from the pressurization initiation end 110, the guide wheel 12 will provide support when the volute tongue component deforms, separating the volute tongue component from the inner wall of the volute housing component 2. This prevents the deformed volute tongue component from contacting the volute housing component 2, preventing the volute tongue component from jamming or rubbing against the inner wall of the volute housing component 2 during movement, thus eliminating abnormal noise and ensuring a good user experience for the air conditioner.

[0040] Specifically, the rotation axis of the guide wheel 12 is parallel to the rotation axis of the worm tongue body 11, and the worm tongue body 11 is provided with a clearance groove 111 for avoiding the wheel body 121.

[0041] A portion of the guide wheel 121 is located within the clearance groove 111 on the volute tongue body 11, while the other portion protrudes from the volute tongue component. The rotation axis of the guide wheel 12 is parallel to the rotation axis of the volute tongue body 11, so that when the volute tongue component rotates within the volute housing component 2, the guide wheel 12 rolls relative to the volute housing component 2, thus avoiding noise generation when the guide wheel 12 and the volute housing component 2 move relative to each other. This ensures the reliability of the relative movement between the guide wheel 12 and the volute housing component 2, and also ensures the reliability of the connection between the guide wheel 12 and the volute tongue body 11.

[0042] like Figure 4 As shown, the guide wheel 12 includes a wheel body 121 and a wheel axle 122 connected to the wheel body 121. One end of the wheel axle 122 is fixedly connected to the wheel body 121, and the other end of the wheel axle 122 is rotatably connected to the volute tongue body 11. A mounting groove 112 for mounting the wheel axle 122 is provided on one side of the clearance groove 111. The wheel body 121 of the guide wheel 12 is rotatably mounted on the volute tongue body 11 via the wheel axle 122.

[0043] like Figure 3 As shown, the mounting groove 112 includes a rotating groove section 1121 and a bayonet groove section 1122 that are interconnected. The rotating groove section 1121 is used to mount the axle 122 for rotation of the axle 122, and the bayonet groove section 1122 is used for the axle 122 to be engaged into the rotating groove section 1121. At least a portion of the rotating groove section 1121 is an arc-shaped groove, and the sidewall of the groove of the rotating groove section 1121 is clearance-fitted with the outer diameter of the axle 122. The bayonet groove section 1122 is a rectangular groove, and the width of the bayonet groove section 1122 is smaller than the outer diameter of the axle 122.

[0044] The guide wheel 12 is directly engaged into the rotating groove 1121 through the bayonet groove 1122 on the volute body 11. The groove width of the bayonet groove 1122 is smaller than the outer diameter of the axle 122 to ensure that the guide wheel 12 will not come out of the bayonet groove 1122. The rotating groove 1121 and the axle 122 are clearance-fitted to allow the guide wheel 12 to rotate relative to the rotating groove 1121.

[0045] Specifically, wheel axles 122 are provided at both ends of the axial direction of the wheel body 121. The wheel body 121 and the two wheel axles 122 are coaxial and integrally formed. Two mounting grooves 112 for mounting the two wheel axles 122 are provided on opposite sides of the clearance groove 111.

[0046] Specifically, the axle 122 can be disposed on both sides of the wheel body 121 or on one side of the wheel body 121. The wheel body 121 of the guide wheel 12 and the axle 122 located on one or both sides of it are integrally formed. When the axle 122 can be disposed on both sides of the wheel body 121, the rotation axes of the two axles 122 located on both sides of the wheel body 121 are coaxial, and the shaft diameters of the two axles 122 are the same.

[0047] Preferably, there are multiple guide wheels 12, which are arranged at intervals along the axial direction of the volute tongue body 11 at the end of the volute tongue body 11 away from the pressurization start end 110. In this way, the multiple guide wheels 12 can better support the volute tongue body 11 from multiple positions along the axial direction of the volute tongue body 11, which is beneficial to the movement of the volute tongue component.

[0048] like Figure 1 As shown, two guide wheels 12 are spaced apart at one end of the volute tongue body 11 away from the pressurization start end 110.

[0049] Specifically, the volute tongue body 11 includes a volute tongue main plate and connecting plates disposed at both axial ends of the volute tongue main plate. The two connecting plates are parallel to each other. The volute tongue main plate is an arc-shaped plate, and the guide wheel 12 is mounted on the volute tongue main plate.

[0050] The present invention provides a fan device, including a volute component 2 and a volute tongue component 1, wherein the volute tongue component is the aforementioned volute tongue component.

[0051] Specifically, the fan device of the present invention is a centrifugal fan with reversible air outlet. The volute tongue component 1 is rotatably arranged in the fan device. The volute tongue component 1 is driven to rotate by a motor and a transmission wheel assembly arranged on the outside of the volute tongue component 1. A portion of the external gear ring is provided on the outer peripheral surface of one end of the volute tongue component 1 for meshing with the gear in the transmission wheel assembly.

[0052] like Figure 6 , Figure 8 , Figure 11 and Figure 13As shown, the fan device also includes a fan blade 3, which is located inside the volute tongue component 1 to provide airflow through the rotation of the fan blade 3.

[0053] like Figure 13 As shown, the volute component 2 includes a first volute portion 21 and a second volute portion 22 arranged opposite to each other along the rotation axis of the fan blade 3 located inside the volute component 2. Both the end of the first volute portion 21 opposite to the volute tongue body 11 and the end of the second volute portion 22 opposite to the volute tongue body 11 are provided with a pointed corner structure 2000.

[0054] Specifically, the volute component 2 includes a first volute portion 21 and a second volute portion 22 disposed opposite to each other. The first volute portion 21 and the second volute portion 22 are respectively located at the two axial ends of the volute tongue component 1. The fan achieves upward and downward airflow through the rotation of the volute tongue component 1. Two guide wheels 12 are spaced apart along the axial direction of the volute tongue body 11 at one end of the volute tongue body 11 away from the pressurization starting end 110, and are respectively used to contact the first volute portion 21 and the second volute portion 22.

[0055] like Figure 5 As shown, the volute component 2 is provided with a first windbreak 201 and a second windbreak 202. The first windbreak 201 and the second windbreak 202 are arranged opposite to each other to form a cavity 203 for mounting the volute tongue component 1 and a first air guide duct 204 and a second air guide duct 205 communicating with the cavity 203. The first air guide duct 204 and the second air guide duct 205 are symmetrical about the rotation axis of the volute tongue body 11. The first windbreak 201 and the second windbreak 202 each include a cavity baffle 2001 and a first air guide plate 2002 and a second air guide plate 2003 provided at both ends of the cavity baffle 2001. The first air guide plate 2002 is tangent to the cavity baffle 2001. The second air guide plate 2003 intersects with the cavity baffle 2001 to form a sharp corner structure 2000.

[0056] In this configuration, a first air guide duct 204 communicating with the cavity 203 is formed between the first air guide plate 2002 of the first windbreak section 201 and the second air guide plate 2003 of the second windbreak section 202; a second air guide duct 205 communicating with the cavity 203 is formed between the second air guide plate 2003 of the first windbreak section 201 and the first air guide plate 2002 of the second windbreak section 202. By rotating the volute tongue component 1 to different positions, one of the air guide ducts is blocked, so that the airflow flows out from the other air guide duct.

[0057] like Figure 6 As shown, the volute tongue component 1 is positioned to block the upward movement of airflow, thereby achieving the downward airflow function of the fan device. Figure 8 As shown, Figure 6 The volute tongue component 1 is formed by rotating 180°, which can block the airflow from moving downwards, so as to realize the upward air outlet function of the fan device.

[0058] The present invention also provides an air conditioner, including a fan device, wherein the fan device is the aforementioned fan device.

[0059] Specifically, the air conditioner of the present invention is a vertical air conditioner with reversible up and down air outlets. The volute component 1 is configured as a movable component with a wind-blocking function to realize the up and down air outlet functions of the air conditioner respectively.

[0060] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0061] The volute tongue component of the present invention has a guide wheel 12 installed at the end of the volute tongue body 11 away from the pressurization initiation end 110. When the volute tongue body 11 moves in a predetermined direction towards a predetermined position of the volute housing component 2, the wheel body 121 of the guide wheel 12 contacts the sharp corner structure 2000 of the volute housing component 2 before the volute tongue body 11 contacts the sharp corner structure 2000 of the volute housing component 2, so as to guide and correct the volute tongue body 11. In this way, the guide wheel 12 can not only prevent the volute tongue component from interfering and jamming with the volute housing component 2 when the deformation of the volute tongue component is too large, thus affecting the movement of the volute tongue component, but also can support the end of the volute tongue component when the deformation of the volute tongue component is small, avoiding abnormal noise caused by the volute tongue component rubbing against the inner wall of the volute housing component 2. This solves the problem in the prior art that the movable volute tongue in the fan is easily deformed, affecting the normal operation of the volute tongue.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
