Description

Technical Field

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

[0002] With economic development, the use of air conditioners has become increasingly popular. Common household air conditioners generally come in two types: wall-mounted units and cabinet units. For round cabinet units, the upper and lower air sweeping blades are located inside the casing and are a certain distance from the air supply outlet. This prevents hot air from immediately falling to the ground when operating in heating mode. For traditional square cabinet units, the upper and lower air sweeping blades are located at the air supply outlet and are positioned higher, making it difficult for them to directly fall to the ground when operating in heating mode. Utility Model Content

[0003] The first purpose of the present invention is to provide a cabinet air supply structure to solve the technical problem that the existing air-conditioning cabinet cannot achieve direct hot air delivery to the ground.

[0004] The utility model provides a cabinet air supply structure, including a front panel and an air sweeping assembly, the front panel is provided with an air supply port, the air sweeping assembly includes a plurality of upper and lower air sweeping blades rotatably arranged at the air supply port, the air sweeping assembly has a closed position and an air supply position; the air supply position includes a hot air landing mode in which the upper and lower air sweeping blades extend obliquely downward, in which at least part of the front edges of the upper and lower air sweeping blades extend forward from the front panel, and the angle between the upper and lower air sweeping blades and the front panel is α, wherein 0°<α≤30°.

[0005] The application of this cabinet air supply structure in an air conditioning cabinet is used as an example for illustration. When the air conditioning cabinet is in heating operation, the air sweeping assembly can be switched to the hot air landing mode in the air supply position. At this time, at least part of the front edges of the upper and lower air sweeping blades extend forward from the front panel, and the angle between the upper and lower air sweeping blades and the front panel is between 0° and 30°. This allows the hot air to flow along the lower surfaces of the upper and lower air sweeping blades as it is blown out through the air supply port. Furthermore, due to the small angle formed between the lower surfaces of the upper and lower air sweeping blades and the front of the front panel, the hot air can also flow downward along the front of the front panel and land on the ground.

[0006] This arrangement ensures that the hot air lands approximately at the front panel, ensuring rapid airflow and preventing it from blowing directly toward the user. This achieves a zero-meter landing effect, effectively resolving the technical issues inherent in existing technologies. Furthermore, by extending the front edges of at least a portion of the upper and lower sweep blades beyond the front panel, the conditioned air is guided by the upper and lower sweep blades to a greater distance, resulting in effective air guidance and rapid heating throughout the home.

[0007] Furthermore, in the air supply position, the upper and lower sweep blades form a maximum angle of 135° with the front panel. This configuration increases the upper and lower sweep range, allowing the upper and lower sweep blades to swing to a larger angle when the air conditioner is powered on, thereby increasing the cooling / heating range and facilitating rapid cooling / heating throughout the home.

[0008] Furthermore, the upper and lower air sweep blades are elongated and extend in the left-right direction. Both left and right ends of the upper and lower air sweep blades are pivotally connected to the front panel, and multiple upper and lower air sweep blades are arranged in the vertical direction. This arrangement increases the lateral dimensions of the upper and lower air sweep blades, making them larger overall, which helps widen the air guide area at the air supply port, thereby enhancing the air guide effect.

[0009] Furthermore, the centerline of the air outlet divides it into an upper half and a lower half. In the hot air falling mode, the leading edges of the upper and lower air sweeping blades located in the lower half extend forward from the front panel. This arrangement ensures that when the air conditioner is operating in heating mode, the hot air blown out of the lower air outlet is not obstructed as it flows downward to the ground, thereby facilitating the hot air to fall to the ground quickly.

[0010] Furthermore, in the hot air drop mode, the distance L by which the leading edges of the upper and lower sweep blades protrude from the front panel is 0 < L ≤ 40 mm. By limiting the distance by which the leading edges of the upper and lower sweep blades protrude from the front panel in the hot air drop mode to within the aforementioned range, not only is the hot air guidance effect ensured, allowing the hot air to be delivered to a greater distance under the guidance of the upper and lower sweep blades, thereby improving the heating efficiency of the indoor space, but the hot air also reaches zero depth, preventing the hot air from dropping far from the front panel due to the upper and lower sweep blades protruding too far from the front panel.

[0011] Furthermore, there are multiple air outlets, which are spaced apart in the vertical direction, and each of which is equipped with the air sweeping assembly. This arrangement can increase the air outlet area of ​​the cabinet air supply structure in the height direction and ensure the air output.

[0012] Furthermore, the upper and lower air sweep blades include a blade body and a rotational axis disposed on the blade body. The blade body is rotatably mounted to the front panel via the rotational axis. In the closed position, the blade body is located downstream of the rotational axis in the air supply direction. This arrangement positions the center of gravity of the blade body further forward, so that during the rotation and closing process of the upper and lower air sweep blades, the blade body tends to swing downward under the action of its own gravity. This swinging action of each blade body closes the gap between adjacent upper and lower air sweep blades, achieving self-closing of the gap.

[0013] Furthermore, the rotating shaft is fixedly disposed relative to the blade body, and the front panel is provided with a rotating hole, in which the rotating shaft is rotatably mounted. This configuration of fixing the rotating shaft to the blade body and providing a rotating hole in the front panel for rotatably engaging the rotating shaft facilitates the simplification of the molding die for the front panel, thereby facilitating the processing and manufacturing of the front panel.

[0014] Furthermore, a stop seal structure is provided between any two adjacent upper and lower sweep blades. This stop seal structure is used to ensure that any two adjacent upper and lower sweep blades overlap in the closed position. This arrangement closes the gap between any two adjacent upper and lower sweep blades when the sweep assembly is in the closed position, effectively preventing impurities from entering the internal cavity of the air conditioner cabinet when it is shut down. Furthermore, the stop seal structure also acts as a rotation limiter for the upper and lower sweep blades when they rotate to the closed position, preventing them from over-rotating.

[0015] The second purpose of the present invention is to provide an air-conditioning cabinet to solve the technical problem that the existing air-conditioning cabinet cannot achieve direct hot air delivery to the ground.

[0016] The air-conditioning cabinet provided by the present invention includes a top cover, a base, a rear panel, a left panel, a right panel and the above-mentioned cabinet air supply structure. The top cover, the base, the front panel, the rear panel, the left panel and the right panel together form a casing, and the rear panel is provided with a return air outlet.

[0017] By setting the above cabinet air supply structure in the air-conditioning cabinet, the air-conditioning cabinet accordingly has all the advantages of the above cabinet air supply structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] 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.

[0029] Figure 1 This is one of the structural diagrams of the air conditioning cabinet provided in this embodiment. Figure 1 As shown, this embodiment provides a cabinet air supply structure, including a front panel 100 and an air sweeping assembly 200. The front panel 100 is provided with an air supply port 110. The air sweeping assembly 200 includes a plurality of upper and lower air sweeping blades 210 rotatably arranged at the air supply port 110. The air sweeping assembly 200 has a closed position and an air supply position.

[0030] Figure 2 A schematic longitudinal section of the air conditioning cabinet provided in this embodiment; Figure 3 for Figure 2 A magnified view of the local structure at point A. Figure 2 and Figure 3 As shown, the air supply position includes a hot air landing mode in which the upper and lower air sweeping blades 210 extend obliquely downward. In the hot air landing mode, at least part of the front edges of the upper and lower air sweeping blades 210 extend forward from the front panel 100, and the angle between the upper and lower air sweeping blades 210 and the front panel 100 is α, where 0°<α≤30°.

[0031] The application of the cabinet air supply structure in an air conditioning cabinet is used as an example for explanation. When the air conditioning cabinet is in heating operation, the air sweeping assembly 200 can be switched to the hot air landing mode in the air supply position. At this time, the front edges of at least part of the upper and lower air sweeping blades 210 extend forward from the front panel 100, and the angle between the upper and lower air sweeping blades 210 and the front panel 100 is between 0° and 30°. As a result, the hot air can flow along the lower surfaces of the upper and lower air sweeping blades 210 when it is blown out through the air supply port 110. Moreover, since the lower surfaces of the upper and lower air sweeping blades 210 form a small angle with the front of the front panel 100, the hot air can also flow downward along the front of the front panel 100 and fall to the ground.

[0032] This arrangement ensures that the hot air lands approximately at the location of the front panel 100, ensuring rapid hot air landing and preventing it from blowing directly toward the user. This achieves a zero-meter landing effect, effectively resolving the technical issues inherent in existing technologies. Furthermore, by allowing at least a portion of the front edges of the upper and lower sweeping blades 210 to extend forward beyond the front panel 100, the conditioned air is guided by the upper and lower sweeping blades 210 to flow to a greater distance, resulting in effective air guidance and rapid heating of the entire home.

[0033] In this embodiment, the maximum included angle between the upper and lower sweeping blades 210 and the front panel 100 is 135°. In other words, the swing angle range of the upper and lower sweeping blades 210 is between 0° and 135°.

[0034] By setting the upper and lower air sweeping blades 210 to swing within the range of 0° to 135°, the upper and lower air sweeping range can be increased. On the one hand, when the air conditioner cabinet is turned on, the upper and lower air sweeping blades 210 can be swung to a larger angle to increase the cooling / heating range, which is beneficial to rapid cooling / heating of the whole house. On the other hand, it can meet the user's requirements for various air outlet angles.

[0035] It should be noted that, when the air sweeping assembly 200 is in the closed position, the angle between the upper and lower air sweeping blades 210 and the front panel 100 is 0°.

[0036] Figure 4 This is the second structural diagram of the air conditioning cabinet provided in this embodiment. Please continue to refer to Figure 1 , and combined with Figure 4 In this embodiment, the upper and lower air sweeping blades 210 are in the shape of long strips. Specifically, the upper and lower air sweeping blades 210 extend in the left and right directions, and the left and right ends of the upper and lower air sweeping blades 210 are rotatably connected to the front panel 100. Multiple upper and lower air sweeping blades 210 are arranged in the up and down directions.

[0037] On the one hand, this arrangement increases the lateral dimensions of the upper and lower air sweeping blades 210, making the overall specifications of the upper and lower air sweeping blades 210 larger, which is beneficial to widening the air guide area at the air supply port 110, thereby enhancing the air guide effect. On the other hand, by rotatably connecting the left and right ends of the upper and lower air sweeping blades 210 to the front panel 100, not only can the upper and lower air sweeping blades 210 be supported at both ends at the same time to suppress the deformation of the upper and lower air sweeping blades 210, but it can also avoid one end of the upper and lower air sweeping blades 210 from getting stuck during the rotation process, thereby ensuring the smooth rotation of the upper and lower air sweeping blades 210.

[0038] In this embodiment, the center line of the air outlet 110 divides it into an upper half and a lower half. In the hot air landing mode, the front edges of the upper and lower sweeping blades 210 arranged in the lower half extend forward from the front panel 100.

[0039] By setting the upper and lower sweeping blades 210 relatively lower in the air supply outlet 110 to extend forward from the front panel 100 in the hot air landing mode, when the air-conditioning cabinet is operating in the heating mode, the hot air blown out through the lower part of the air supply outlet 110 will not be blocked in the process of flowing downward to the ground, which is conducive to the hot air falling to the ground quickly.

[0040] Please continue to refer to Figure 3 In this embodiment, in the hot air landing mode, the front edges of the upper and lower sweeping blades 210 protrude from the front panel 100 by a distance L, where 0<L≤40mm.

[0041] By limiting the distance that the front edges of the upper and lower sweeping blades 210 protrude from the front panel 100 in the hot air landing mode to within the above-mentioned range, not only can the hot air guiding effect be ensured, so that the hot air can be sent to a longer distance under the guidance of the upper and lower sweeping blades 210, thereby improving the heating efficiency of the indoor space, but also the hot air zero-meter landing effect can be ensured, avoiding the hot air landing position being far away from the front panel 100 due to the upper and lower sweeping blades 210 protruding too far from the front panel 100.

[0042] Please continue to refer to Figure 1 and Figure 4 In this embodiment, there are two air supply ports 110 , which are spaced apart in the vertical direction, and each air supply port 110 is equipped with an air sweeping assembly 200 .

[0043] By setting the number of air outlets 110 to two, not only can the air outlet area of ​​the cabinet air supply structure be increased in the height direction to ensure the air outlet volume, but also, after the cabinet air supply structure is applied to the air-conditioning cabinet, it will not cause the air-conditioning cabinet to be too high, thereby avoiding the risk of tipping over due to the increased center of gravity.

[0044] In other embodiments, the air outlets 110 may be provided in other numbers and arrangements, which are not limited in this embodiment.

[0045] Figure 5 for Figure 4 The enlarged view of the local structure at B in the middle. Please continue to refer to Figure 4 , and combined with Figure 5 In this embodiment, the upper and lower air sweeping blades 210 include a blade body 211 and a rotation shaft 212 disposed on the blade body 211. The blade body 211 is rotatably mounted to the front panel 100 via the rotation shaft 212. In the closed position, the blade body 211 is located downstream of the rotation shaft 212 in the air supply direction. In other words, in the closed position, the rotation shaft 212 is located on the back side of the blade body 211.

[0046] By positioning the blade body 211 downstream of the rotation axis 212 in the airflow direction, the center of gravity of the blade body 211 is positioned further forward. As a result, during the rotational closing process of the upper and lower air sweeping blades 210, the blade body 211 tends to swing downward under its own gravity. This swinging action of each blade body 211 closes the gap between adjacent upper and lower air sweeping blades 210, achieving self-closing of the gap. This closing process of the upper and lower air sweeping blades 210 effectively reduces the load on the drive assembly that drives the air sweeping assembly 200 to the closed position, maintaining the upper and lower air sweeping blades 210 in the closed position without requiring the drive assembly to continuously provide a high driving torque.

[0047] Please continue to refer to Figure 5 In this embodiment, the rotating shaft 212 and the blade body 211 are fixedly arranged relative to each other, and the front panel 100 is provided with a rotating hole 120 , and the rotating shaft 212 is rotatably installed in the rotating hole 120 .

[0048] This form of fixing the rotating shaft 212 to the blade body 211 and providing the rotating hole 120 on the front panel 100 for rotating with the rotating shaft 212 is conducive to simplifying the molding die of the front panel 100, thereby facilitating the processing and manufacturing of the front panel 100.

[0049] Please continue to refer to Figure 3 In this embodiment, a stop sealing structure 220 is provided between any two adjacent upper and lower air sweeping blades 210, wherein the stop sealing structure 220 is used to overlap and fit any two adjacent upper and lower air sweeping blades 210 in the closed position.

[0050] By setting the above-mentioned stop sealing structure 220, when the air sweeping assembly 200 is in the closed position, the gap between any two adjacent upper and lower air sweeping blades 210 is closed, effectively preventing impurities from entering the inner cavity of the air-conditioning cabinet when the air-conditioning cabinet is in the shutdown state. Moreover, the stop sealing structure 220 can also play a rotation limiting role for the upper and lower air sweeping blades 210 when they are rotated to the closed position, preventing the upper and lower air sweeping blades 210 from excessive rotation.

[0051] Please continue to refer to Figure 3 In this embodiment, the stop sealing structure 220 may include a first inclined surface 221 and a second inclined surface 222 for overlapping fit, wherein the first inclined surface 221 is arranged on the upper and lower air sweeping blades 210 and is located behind the upper and lower air sweeping blades 210, and the first inclined surface 221 extends obliquely from bottom to top toward the direction close to the inner cavity of the air-conditioning cabinet; the second inclined surface 222 is arranged on the lower upper and lower air sweeping blades 210 and is located in front of the upper and lower air sweeping blades 210, and the second inclined surface 222 also extends obliquely from bottom to top toward the direction close to the inner cavity of the air-conditioning cabinet.

[0052] This form of the stop sealing structure 220 formed by overlapping the first bevel 221 and the second bevel 222 ensures that the gap between the two adjacent upper and lower wind sweeping blades 210 is reliably closed in the closed position, and also enables the air-conditioning air to be discharged along the first bevel 221 and the second bevel 222 when the wind sweeping assembly 200 is in the air supply position, thereby achieving the guidance of the air-conditioning air at the edge of the blade body 211, so as to reduce the vortex and noise of the air-conditioning air at the edge of the blade body 211.

[0053] In addition, this embodiment also provides an air-conditioning cabinet, including a top cover 300, a base 400, a rear panel 500, a left side panel 600, a right side panel 700 and the above-mentioned cabinet air supply structure, wherein the top cover 300, the base 400, the front panel 100, the rear panel 500, the left side panel 600 and the right side panel 700 together form a casing, and the rear panel 500 is provided with a return air outlet 510.

[0054] By setting the above cabinet air supply structure in the air-conditioning cabinet, the air-conditioning cabinet accordingly has all the advantages of the above cabinet air supply structure, which will not be described in detail here.

[0055] It should be noted that, generally speaking, one side of the air-conditioning cabinet is the side facing the indoor space or the indoor user activity area, which is the front side of the air-conditioning cabinet; and the side of the air-conditioning cabinet facing the corner or the wall is its back side. When the user stands facing the front side of the air-conditioning cabinet, the left side of the user is the left side of the air-conditioning cabinet, and the right side of the user is the right side of the air-conditioning cabinet. Specifically in this embodiment, the "front and back direction", "left and right direction" and "up and down direction" of the air-conditioning cabinet are respectively as follows: Figure 1 As indicated by the corresponding arrows.
