Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a cabinet air-correcting mechanism and an air conditioner. Background Art

[0002] Cabinet air conditioners with axial flow fans, as indoor air conditioners, offer advantages such as a small footprint and high airflow. While some existing technologies employ a spiral mesh at the air duct outlet to rectify the airflow, this not only makes it difficult to configure sweeping blades to control the angle of the airflow or to oscillate the airflow direction, but also reduces the airflow rectification effect due to the limited width of the spiral mesh. Utility Model Content

[0003] The first aspect of the present invention aims to provide a cabinet air-correcting mechanism to solve the technical problem of insufficient air blowing distance of existing cabinets.

[0004] The utility model provides a cabinet air-correcting mechanism in the first aspect, comprising a sweeping blade and a wind-correcting grille, wherein the sweeping blade is located at the cabinet air outlet, and the wind-correcting grille is located in the cabinet air outlet duct and behind the sweeping blade.

[0005] The beneficial effects of the utility model cabinet wind correction mechanism are:

[0006] By arranging the wind-rectifying grilles and the sweeping blades in sequence along the airflow direction, the upstream wind-rectifying grilles can first rectify the airflow generated by the axial fan, making it smoother. Then, because the sweeping blades have width in the airflow direction, they can further rectify and straighten the airflow that has passed through the wind-rectifying grilles, improving the stability of the airflow and allowing the airflow to reach a greater distance. Moreover, the sweeping blades can be used to control the direction of the airflow, making the airflow outflow at different angles or causing the airflow to oscillate back and forth.

[0007] In an optional technical solution, the wind-correcting grille includes an outer frame and a plurality of spaced-apart grille bars; one end of the grille bar is fixed to the outer frame, and the other end is fixed to the central area surrounded by the outer frame, and the cross-sectional profile of the grille bar is a first arc-shaped structure, and the cross-section is a cross-section perpendicular to the axial direction of the frame; the bending direction of the first arc-shaped structure is consistent with the rotation direction of the axial fan of the cabinet, and the bending direction is the extension direction of the first arc-shaped structure from the end close to the central area to the end close to the outer frame.

[0008] Such a setting can ensure that when the airflow with a centripetal rotation angle passes through the grille bars, the grille bars can guide the airflow along its centripetal angular velocity direction, reduce the resistance of the grille bars to the outgoing airflow, thereby reducing the loss of air output and controlling the outgoing air noise.

[0009] In an optional technical solution, the thickness of the grille bars gradually increases from the rear end portion to the front end portion, and the width of the wind-correcting air duct formed between adjacent grille bars gradually decreases.

[0010] With this arrangement, the cross section of the air flow gradually narrows when the air flow passes through the wind-correcting duct, thereby increasing the air flow velocity and being beneficial to increasing the air supply distance.

[0011] In an optional technical solution, the wind-correcting grille also includes an inner frame and a grille ring, the inner frame is located in the central area surrounded by the outer frame, and the grille bars are fixed to the annular area formed between the inner frame and the outer frame; the grille ring is located in the annular area between the outer frame and the inner frame, and is fixed to the grille bars; the inner frame, the grille ring and the outer frame are coaxial; the grille ring divides the annular area between the outer frame and the inner frame into an outer ring area and an inner ring area, and the number of grille bars located in the outer ring area is greater than the number of grille bars located in the inner ring area.

[0012] In this way, the grille rings in the inner and outer frames help reduce the length of the grille bars, which not only improves the strength of the grille bars, but also allows for flexible arrangement of the number, size, position, and shape of the grille bars as needed, improving adaptability to airflow and increasing airflow distance. By increasing the density of the grille bars in the outer annular area of ​​the wind-correcting grille, it facilitates better rectification and correction of high-velocity airflow.

[0013] In an optional technical solution, the longitudinal section profile of the grille bar is a second arc-shaped structure, the rear end of the second arc-shaped structure gradually rises toward the outer frame, and the longitudinal section is the plane where the axis of the wind-correcting grille is located.

[0014] With this arrangement, after the airflow hits the grille bars, the tangential velocity component of the airflow velocity generated by the axial fan can be gradually converted into an axial velocity component, so that the resulting airflow can be blown to a position farther in front of the cabinet.

[0015] In an optional technical solution, the wind sweeping blades include left and right wind sweeping blades and upper and lower wind sweeping blades, the left and right wind sweeping blades are located behind the upper and lower wind sweeping blades, and the wind sweeping directions of the left and right wind sweeping blades intersect with the wind sweeping directions of the upper and lower wind sweeping blades.

[0016] By setting left and right sweeping blades and upper and lower sweeping blades, the airflow blown out by the axial fan can be rectified by using the left and right sweeping blades and the upper and lower sweeping blades respectively, so as to form a three-layer wind-rectifying structure of wind-rectifying grille, left and right sweeping blades and upper and lower sweeping blades, which significantly improves the rectification and correction effect of the airflow, so that the outlet airflow can be blown to a farther location.

[0017] In an optional technical solution, the upper and lower air-sweeping blades include a first air-sweeping blade, the first air-sweeping blade is provided with a second protrusion, and the second protrusion is located at the end of the length direction of the first air-sweeping blade; when the width direction of the first air-sweeping blade is parallel to the axis of the wind-correcting grille, the second protrusion protrudes backward.

[0018] By setting a first air sweeping blade and setting a second protrusion at the end of the first air sweeping blade, so that the second protrusion protrudes rearward when the first air sweeping blade is parallel to the axis of the wind correction grille, the local air guide length of the fourth air guide blade for the air flow can be increased, thereby improving the directionality of the air flow so that the blown air flow can be blown to a farther position.

[0019] In an optional technical solution, the left and right air sweeping blades include a second air sweeping blade, the second air sweeping blade is provided with a second recessed portion, and the second recessed portion is arranged opposite to the second raised portion.

[0020] By providing a second recessed portion on at least part of the left and right sweep blades, and disposing the second raised portion opposite to the second recessed portion, sufficient space can be provided for the first sweep blade having the second raised portion to swing, thereby facilitating a reduction in the distance between the rotation axis of the upper and lower sweep blades and the rotation axis of the left and right sweep blades, making the cabinet having the cabinet airflow correction mechanism more compact in the front-to-back direction. Moreover, the second raised portion can be viewed along the rotation axis of the left and right sweep blades, thereby forming an overlapping guide for the airflow direction. At a position where the airflow guiding effect of the left and right sweep blades is less lost, the upper and lower sweep blades can continue to guide the airflow, thereby improving the continuity of the airflow guidance, thereby improving the airflow guiding effect, and allowing the gas blown out of the cabinet to be blown to a farther location.

[0021] In an optional technical solution, the upper and lower air-sweeping blades include a third air-sweeping blade, and a third protrusion is provided at the end of the third air-sweeping blade, and the third protrusion is located at the end of the length direction of the third air-sweeping blade; when the width direction of the third air-sweeping blade is parallel to the axis of the wind correction grille, the third protrusion protrudes forward.

[0022] By setting a third air sweeping blade and setting a second protrusion at the end of the third air sweeping blade, so that the second protrusion protrudes rearward when the third air sweeping blade is parallel to the axis of the wind correction grille, the local air guiding length of the fourth air guide blade for the air flow can be increased, thereby improving the directionality of the air flow so that the blown air flow can be blown to a farther position.

[0023] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem of insufficient air blowing distance of cabinet units.

[0024] The air conditioner provided in the second aspect of the present invention includes a cabinet unit, wherein the cabinet unit includes an air duct mounting plate, and the air duct mounting plate is installed with any of the above-mentioned cabinet unit wind correction mechanisms.

[0025] By arranging the above-mentioned cabinet air-correcting mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned cabinet air-correcting mechanism, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Unless otherwise specified, the definitions of directions in this application are as follows: the front refers to the side of the cabinet facing the main indoor space, and the back refers to the side of the cabinet facing the wall it is adjacent to. The bottom refers to the side of the cabinet facing the ground. The top refers to the side of the cabinet facing the roof.

[0036] 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.

[0037] Example 1:

[0038] Figure 1 This is a schematic diagram of the structure of the cabinet air correction mechanism provided in the first embodiment of the present invention applied to the cabinet; Figure 1 As shown, the cabinet air-correcting mechanism provided in the first embodiment of the present invention includes an air-sweeping blade 200 and an air-correcting grille 100 . The air-correcting grille 100 is located in the air outlet duct of the cabinet and behind the air-sweeping blade 200 .

[0039] By arranging the wind-correcting grille 100 and the wind-sweeping blades 200 in sequence along the direction of the airflow, the wind-correcting grille 100 located upstream can first correct the airflow generated by the axial fan 320 to make it smoother. Then, since the wind-sweeping blades 200 have width in the direction of the airflow, the wind-sweeping blades 200 can also further rectify and correct the airflow passing through the wind-correcting grille 100, thereby improving the stability of the airflow and allowing the airflow to blow to a farther range.

[0040] Specifically, the cabinet unit used in this embodiment includes an air duct mounting plate 330 and a rear panel 340. The rear panel 340 is provided with an air inlet 341, and an indoor heat exchanger 350 is located in front of the rear panel 340. The cabinet unit's wind-rectifying mechanism can be mounted on the air duct mounting plate 330, in front of the axial fan 320. Driven by the axial fan 320, air enters through the air inlet 341 of the rear panel 340 and exchanges heat with the indoor heat exchanger 350. The rotation of the axial fan 320 generates airflow, and the wind-rectifying grille 100 adjusts the airflow, converting at least part of the tangential velocity component of the airflow into an axial velocity component. This airflow is then further rectified by the sweeping blades 200, increasing the axial velocity component and facilitating its propulsion to a greater distance. Furthermore, the sweeping blades 200 can be used to control the airflow's outlet direction, directing the outlet airflow at different angles or causing the outlet airflow to oscillate back and forth.

[0041] In this embodiment, the wind correcting grille 100 is coaxially arranged with the motor 310 and the axial flow fan 320 , that is, the axis of the wind correcting grille 100 coincides with the axis of the motor 310 and the axis of the axial flow fan 320 .

[0042] like Figure 1-Figure 2 As shown, optionally, the wind-correcting grille 100 includes an outer frame 140 and a plurality of spaced-apart grille bars 110; one end of the grille bar 110 is fixed to the outer frame 140, and the other end is fixed to the central area surrounded by the outer frame 140, and the cross-sectional profile of the grille bar 110 is a first arc-shaped structure, and the cross-section is a section perpendicular to the axis direction of the frame.

[0043] Such a setting can, on the one hand, reduce the turbulence generated when the flowing air encounters the grille bars 110, thereby reducing noise; on the other hand, it can reduce the loss of dynamic pressure and is conducive to recovering the dynamic pressure of the rotating flow generated by the fan as static pressure.

[0044] Optionally, the bending direction of the first arc structure is consistent with the rotation direction of the axial flow fan 320 of the cabinet, and the bending direction is the extension direction of the first arc structure from the end close to the central area to the end close to the outer frame 140.

[0045] With such a setting, when the airflow with a centripetal rotation angle passes through the grille bar 110, the grille bar 110 can guide the airflow in an inclined direction along its centripetal angular velocity, thereby reducing the resistance of the grille bar 110 to the outgoing airflow, thereby reducing the loss of the outgoing air volume and controlling the outgoing air noise.

[0046] Specifically, each grille bar 110 curves and extends radially; radially outward, the extension and curvature of the grille bars 110 is the same as the rotation direction of the axial flow fan 320. In this embodiment, the axial flow fan rotates clockwise when viewed from the front, so radially outward, the grille bars 110 also curve clockwise.

[0047] like Figure 1 As shown, optionally, the thickness of the grille bars 110 gradually increases from the rear end portion to the front end portion thereof, and the width of the wind-correcting air duct formed between adjacent grille bars 110 gradually decreases.

[0048] The thickness of the grille bars 110 gradually increases, which means that the airflow cross section gradually narrows when the airflow passes between adjacent grille bars 110, thereby increasing the airflow speed and facilitating an increase in the air supply distance.

[0049] like Figure 1 and Figure 2 As shown, optionally, the wind-correcting grille 100 further includes an inner frame 120 and a grille ring 130, the inner frame 120 being located in the central area surrounded by the outer frame 140, the grille bars 110 being fixedly connected to the annular area formed between the inner frame 120 and the outer frame 140, the grille ring 130 being located in the annular area between the outer frame 140 and the inner frame 120, and being fixedly connected to the grille bars 110; the inner frame 120, the grille ring 130 and the outer frame 140 are coaxial.

[0050] In this way, setting the grille ring 130 in the inner frame 120 and the outer frame 140 is beneficial to reducing the length of the grille bars 110. On the one hand, it improves the strength of the grille bars 110. On the other hand, by setting the grille ring 130, the number, size, position and shape of the grille bars 110 can be flexibly arranged as needed to improve the adaptability to airflow and increase the air outlet distance.

[0051] like Figure 2 As shown, optionally, the grille ring 130 divides the annular area between the outer frame 140 and the inner frame 120 into an outer annular area and an inner annular area, and the number of grille bars 110 in the outer annular area is greater than the number of grille bars 110 in the inner annular area.

[0052] Such an arrangement increases the density of the grille bars 110 in the outer annular region of the wind-rectifying grille 100 , thereby facilitating better rectification and airflow correction for a relatively high-speed airflow.

[0053] Specifically, in this embodiment, the number of first grille bars 111 in the outer annular region can be 10%-60% greater than the number of second grille bars 112 in the inner annular region. Furthermore, the radially outer ends of the first grille bars 111, on both the windward and leeward sides, also form larger angles with the axis of the wind-correcting grille 100 than the radially outer ends of the second grille bars 112. The inner frame 120, grille ring 130, and outer frame 140 are all annular.

[0054] like Figure 1 and Figure 2 As shown, optionally, the longitudinal section profile of the grille bar 110 is a second arc structure, the rear end of the second arc structure gradually rises toward the outer frame 140, and the longitudinal section is the plane where the axis of the wind correction grille 100 is located.

[0055] With this arrangement, after the airflow reaches the grille bars 110 , the tangential velocity component of the airflow velocity generated by the axial flow fan 320 can be gradually converted into an axial velocity component, so that the resulting airflow can be blown to a position farther in front of the cabinet.

[0056] Along the axial direction of the wind-correcting grille 100, the longitudinal section of the grille bar 110 gradually approaches the axis of the wind-correcting grille 100. Specifically, Figure 1 As shown in the partial enlarged figure, Figure 1 The longitudinal section of the grille bar 110 located above the axis is high on the right and low on the left. Figure 1 It is reflected from right to left. So Figure 1 The grille bars 110 above the central axis are arranged forward along the axial direction of the wind-correcting grille 100, and the longitudinal section of the grille bars 110 gradually approaches the axis of the wind-correcting grille 100. Figure 1 The longitudinal cross-section of the grille bars 110 below the axis is lower on the right and higher on the left. Therefore, as the grille bars 110 below the axis move forward along the axial direction of the wind-correcting grille 100, the cross-section gradually approaches the axis of the wind-correcting grille 100. In other words, the rear end of the grille bars 110 gradually rises toward the outer frame 140.

[0057] Moreover, as the longitudinal section of the grille bar 110 gradually approaches the axis of the wind correcting grille 100 along the axial direction of the wind correcting grille 100, the windward edge 113 and the leeward edge 114 gradually approach the axis of the wind correcting grille 100. This means that the angle between the windward edge 113 and the leeward edge 114 of the cross section and the wind correcting grille 100 gradually decreases. Figure 1 As shown in the partially enlarged content, at the front end of the grille bar 110, that is, the end along the flow direction of the airflow, the windward surface of the grille bar 110 can be parallel to the axis of the wind correction grille 100.

[0058] like Figure 1-Figure 2As shown, optionally, along the radial outward direction of the wind correcting grille 100 , the angles between the windward side and the leeward side of the grille bars 110 and the axial direction of the wind correcting grille 100 gradually increase.

[0059] Because the larger diameter portion of the axial fan 320, i.e., the radial edge of the axial fan 320, can generate a faster wind speed when the axial fan 320 rotates, the tangential velocity component of this portion of the airflow is larger, causing the windward and leeward sides of the grille bars 110 to gradually increase their angle with the axial direction of the wind-correcting grille 100 in a radially outward direction. This allows the radially larger area of ​​the grille bars 110, i.e., the outer annular area, to contact and rectify the airflow with a larger tangential velocity component, while the radially smaller area of ​​the grille bars 110, i.e., the inner area, to contact and rectify the airflow with a smaller tangential velocity component. Thus, the rear end of the grille bars 110 can more smoothly contact and gradually guide the airflow with a tangential velocity component in a direction where the axial velocity component is maximized and the tangential velocity component is minimized, thereby reducing noise during the operation of the cabinet unit, reducing airflow velocity losses, and extending the airflow range of the cabinet unit.

[0060] Moreover, the windward and leeward sides of the grille bar 110 are arranged in a radially outward direction, with the angle with the axial direction gradually increasing, so that the airflow at the edge of the wind-correcting grille 100 can be converged to the central area to a certain extent, thereby improving the uniformity of the airflow velocity at different radial size positions, so as to avoid the airflow velocity at the edge position being too protruding and encountering too much resistance after being blown out of the cabinet.

[0061] Specifically, Figure 2 The lower left side of the picture is the front side of the wind-correcting grille 100. Figure 2 The upper right side of the image is the rear side of the wind-correcting grille 100. Figure 2 As shown in the partially enlarged portion, if the windward and leeward sides of the grille bar 110 are at the same angle with the axial direction in the radially outward direction, then even if the angle between the grille bar 110 and the axial direction gradually decreases along the airflow direction, the front and rear upper edges of the grille bar 110 in the enlarged portion should be parallel, and the rear upper edge should be completely translated with the front upper edge. However, it is clearly visible that the distance between the rear upper edge and the front upper edge in the figure increases significantly from left to right in the image. This indicates that the rear upper edge of the grille bar 110 increases in elevation from left to right relative to the front upper edge, so at this projection angle, the left side width of the grille bar 110 appears smaller than the right side width. In this partially enlarged view, the upper surface of the grille bar 110 is the windward side, while the lower surface is the leeward side.

[0062] Figure 3A three-dimensional cross-sectional view of a cabinet unit in which the cabinet unit wind-correcting mechanism provided in the first embodiment of the present invention is applied; Figure 4 This is an external view of the cabinet to which the wind-correcting mechanism provided in the first embodiment of the present invention is applied. Figure 1 、 Figure 3 and Figure 4 As shown, optionally, the air sweep blades 200 include left and right air sweep blades 210 and upper and lower air sweep blades 230 , and the left and right air sweep blades 210 are located behind the upper and lower air sweep blades 230 .

[0063] By setting left and right sweeping blades 210 and upper and lower sweeping blades 230, the left and right sweeping blades 210 and upper and lower sweeping blades 230 can be used to rectify the airflow blown out by the axial fan 320 respectively, so as to form a three-layer wind rectification structure of the wind rectification grille 100, left and right sweeping blades 210 and upper and lower sweeping blades 230, which significantly improves the rectification and rectification effect of the airflow, and is conducive to allowing the outlet airflow to be blown to a farther location.

[0064] In this embodiment, the left and right sweep blades 210 rotate vertically, while the upper and lower sweep blades 230 rotate horizontally. Especially when both the left and right sweep blades 210 and the upper and lower sweep blades 230 are parallel to the axis of the axial fan 320, the three-layer wind-correcting structure achieves a more effective wind-correcting effect, helping the airflow reach a wider area.

[0065] In this embodiment, the wind correcting grille 100 includes a receiving portion 150 , which is used to receive a portion of the motor 310 , and the receiving portion 150 protrudes forward.

[0066] like Figure 1 and Figure 3 、 Figure 4 As shown, optionally, the upper and lower air sweeping blades 230 include a first air sweeping blade 240, and the first air sweeping blade 240 is provided with a second protrusion 241, and the second protrusion 241 is located at the end of the length direction of the first air sweeping blade 240; when the width direction of the first air sweeping blade 240 is parallel to the axis of the wind correction grille 100, the second protrusion 241 protrudes backward.

[0067] By providing a first air sweeping blade 240 and providing a second protrusion 241 at the end of the first air sweeping blade 240, so that the second protrusion 241 protrudes rearward when the first air sweeping blade 240 is parallel to the axis of the wind correction grille 100, the local air guide length of the first air sweeping blade 240 for the air flow can be increased, thereby improving the directionality of the air flow so that the blown air flow can be blown to a farther position.

[0068] Furthermore, in this embodiment, there are six upper and lower air sweeping blades 230, which are arranged in a vertical direction. The first air sweeping blade 240 is a portion of the three upper and lower air sweeping blades 230 located at the top, for example, the second and third upper and lower air sweeping blades 230 from the top to the bottom.

[0069] like Figure 1 and Figure 3 、 Figure 4 As shown, optionally, the left and right air sweeping blades 210 include a second air sweeping blade 211 , and the second air sweeping blade 211 is provided with a second recessed portion 213 , and the second recessed portion 213 is arranged opposite to the second raised portion 241 .

[0070] By providing a second recessed portion 213 on the second sweeping blade 211, which is arranged opposite to the second raised portion 241, sufficient space can be provided for the first sweeping blade 240 having the second raised portion 241 to swing, thereby facilitating a reduction in the distance between the rotation axis of the upper and lower sweeping blades 230 and the rotation axis of the left and right sweeping blades 210, making the cabinet equipped with this cabinet airflow correction mechanism more compact in the front-to-back direction. Moreover, when viewed along the rotation axis of the left and right sweeping blades 210, the second raised portion 241 can form an overlapping guide with the left and right sweeping blades 210 in the direction of the airflow flow. At a position where the airflow guiding effect of the left and right sweeping blades 210 is less lost, the upper and lower sweeping blades 230 can continue to guide the airflow, thereby improving the continuity of the airflow guidance, thereby improving the airflow guiding effect, and allowing the air blown out of the cabinet to be blown to a farther location.

[0071] Specifically, in this embodiment, there are four left and right air sweep blades 210. The first and fourth left and right air sweep blades 210 from left to right are second air sweep blades 211. The upper portions of the second air sweep blades 211 are provided with second recesses 213. Although the second and third upper and lower air sweep blades 230 from top to bottom in this embodiment are provided with second protrusions 241, the two second protrusions 241 of the third upper and lower air sweep blade 230 are spaced far apart and are located to the left of the first left and right air sweep blade 210 and to the right of the fourth left and right air sweep blade 210 from left to right, respectively. Therefore, the swinging of the third upper and lower air sweep blade 230 does not cause the second protrusions 241 thereon to interfere with the second air sweep blades 211. Therefore, the left and right air sweep blades 210 do not provide second recesses 213 corresponding to the second protrusions 241 of the third upper and lower air sweep blade 230.

[0072] Since the distance between the two second protrusions 241 of the second upper and lower air sweeping blades 230 is smaller than the second protrusion 241 of the third upper and lower air sweeping blades 230, the second protrusions 241 of the second upper and lower air sweeping blades 230 will interfere with the upper portions of the first and fourth left and right air sweeping blades 210. Therefore, a second recess 213 is provided on the upper portion of the second air sweeping blade 211. The opening of the second recess 213 faces forward when the left and right air sweeping blades 210 are parallel to the axis of the wind control grille 100. More specifically, the second recess 213 may be an arc-shaped recess.

[0073] like Figure 1 and Figure 3 、 Figure 4 As shown, optionally, the upper and lower air sweeping blades 230 include a third air sweeping blade 250, and the end of the third air sweeping blade 250 is provided with a third protrusion 251, and the third protrusion 251 is located at the end of the length direction of the third air sweeping blade 250; when the width direction of the third air sweeping blade 250 is parallel to the axis of the wind correction grille 100, the third protrusion 251 protrudes forward.

[0074] By setting a third air sweeping blade 250 and setting a second protrusion 241 at the end of the third air sweeping blade 250, so that the second protrusion 241 protrudes backward when the third air sweeping blade 250 is parallel to the axis of the wind correction grille 100, the local air guiding length of the fourth air guide blade for the air flow can be increased, thereby improving the directionality of the air flow so that the blown air flow can be blown to a farther position.
