Description

Technical Field

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

[0002] Typically, cabinet air conditioners have air outlets on their air outlet panels. When the cabinet air conditioner is operating in cooling mode, the cold air coming out of the outlets directly meets the hot air outside the air outlet panel, causing condensation around the outlets. Utility Model Content

[0003] The purpose of the utility model is to provide an air-conditioning cabinet unit to solve the technical problem that condensation is easily generated around the air outlet when the existing air-conditioning cabinet unit is operated in a cooling mode.

[0004] The air-conditioning cabinet provided by the present invention includes an air outlet panel with an air supply outlet, the air outlet panel has an inner surface facing the inner cavity of the machine body and an outer surface opposite to the inner surface, the air outlet panel includes a guide slope, the guide slope is arranged around the air supply outlet, and the guide slope connects the edge of the air supply outlet and the outer surface, wherein, along the direction of air flow passing through the air supply outlet, the guide slope extends obliquely in a direction away from the center of the air supply outlet.

[0005] By setting a guide slope connecting the edge of the air supply outlet and the outer surface of the air outlet panel on the air outlet panel, when the air flow is sent out through the air supply outlet, when the air flow flows through the edge of the air supply outlet, it will be guided by the guide slope under the Coanda effect. For example, when the air conditioner cabinet is operating in cooling mode, when the cold air is sent out through the air supply outlet, it will flow along the guide slope toward the outer surface of the air outlet panel, that is, the air flow will diffuse outward to the front surface of the air outlet panel the moment it is sent out through the air supply outlet, so that the air outlet panel can also blow cold air around the air supply outlet, and the cold air is used to isolate the air outlet panel from the hotter air in the room to prevent condensation from forming around the air supply outlet.

[0006] Furthermore, the edge of the air outlet is provided with a linear guide segment, which surrounds the air outlet and extends along the direction of airflow passing through the air outlet. The air outlet is connected to the guide slope via the linear guide segment. This arrangement ensures that the airflow maintains its original path upon entering the air outlet, avoiding impact noise and turbulence caused by the airflow turning at an excessively large angle upon entering the air outlet, and ensuring the smoothness of the airflow.

[0007] Furthermore, the diversion slope is a plane, which is easy to manufacture.

[0008] Furthermore, the angle α between the guide slope and the radial cross-section of the air outlet is 40° < α < 60°. This configuration not only prevents a situation in which α is too small, causing most of the airflow to be directed to the outer surface of the air outlet panel, thereby reducing the amount of air blown into the room, but also prevents a situation in which α is too large, causing the airflow to be unable to be directed to the outer surface of the air outlet panel, thereby reducing the anti-condensation effect.

[0009] Furthermore, the guide slope is formed by chamfering the edge of the air outlet panel on the air outlet. This method of forming the guide slope on the air outlet panel using a chamfering process allows the linear guide section to be processed simultaneously. The linear guide section and the guide slope are both solid structures with a certain thickness. While improving production efficiency, it also ensures the structural stability of the linear guide section and the guide slope, and reduces deformation of the linear guide section and the guide slope.

[0010] Furthermore, a transition fillet is provided between the guide slope and the outer surface, which not only avoids the user's hand being scratched due to the sharp junction between the guide slope and the outer surface, but also makes the edge of the air outlet look more rounded.

[0011] Furthermore, the air outlet is circular. This circular shape ensures a high air volume while reducing machining stress at the outlet edge. Alternatively, there are multiple air outlets, each spaced apart vertically. This arrangement increases the air outlet area of ​​the cabinet air conditioner in the vertical direction, ensuring high air volume.

[0012] Furthermore, the air supply port is provided with an air sweep assembly, which has a closed position for closing the air supply port and an air guiding position for at least partially exposing the air supply port. This cabinet air conditioner not only utilizes the action of the air sweep assembly to guide air when in operation, thus meeting the cabinet air conditioner's multi-angle air supply requirements, but also utilizes the air sweep assembly to block the air supply port when in shutdown, achieving the purpose of closing the air supply port. This eliminates the need for a separate sliding panel for closing the air supply port, thereby effectively simplifying the cabinet air conditioner's structure.

[0013] Furthermore, the air sweep assembly includes a plurality of air sweep blades arranged in a vertical direction, the plurality of air sweep blades being rotatably connected to the air outlet panel. A stop seal structure is provided between any two adjacent air sweep blades, the stop seal structure being used to ensure that any two adjacent air sweep blades overlap in the closed position. The stop seal structure seals the gap between any two adjacent blades when the air 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, and ensuring the cleanliness of the cabinet's external structure.

[0014] Furthermore, an air supply assembly is provided at the air outlet, comprising a drive motor and an air supply impeller. The drive motor body is fixedly mounted relative to the air outlet panel, the drive motor shaft extending in the front-to-back direction, and the air supply impeller is fixedly mounted on the motor shaft, with the air supply impeller facing the air outlet. This arrangement of the air supply assembly is structurally simple and facilitates reducing the front-to-back dimensions of the air conditioner cabinet, facilitating a thinner design for the air conditioner cabinet.

[0025] 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.

[0026] Figure 1 A schematic cross-sectional view of the air conditioning cabinet provided in this embodiment; Figure 2 This is a schematic diagram of the structure of the air conditioning cabinet provided in this embodiment. Figure 3 This is a schematic diagram of the longitudinal structure of the air conditioning cabinet provided in this embodiment. Figures 1 to 3 As shown, this embodiment provides an air conditioning cabinet, including an air outlet panel 100 with an air outlet 130 , the air outlet panel 100 has an inner surface 110 facing the inner cavity of the machine body and an outer surface 120 opposite to the inner surface 110 .

[0027] Figure 4 for Figure 3 A magnified view of the local structure at point A. Please continue to refer to Figure 3 , and combined with Figure 4 The air outlet panel 100 also includes a guide slope 140. Specifically, the guide slope 140 is arranged around the air outlet 130, and the guide slope 140 connects the edge of the air outlet 130 and the outer surface 120. In the direction of the air flow passing through the air outlet 130, the guide slope 140 extends obliquely in a direction away from the center of the air outlet 130.

[0028] By providing a guide slope 140 connecting the edge of the air supply outlet 130 and the outer surface 120 of the air outlet panel 100 on the air outlet panel 100, when the air flow is sent out through the air supply outlet 130, when the air flow flows through the edge of the air supply outlet 130, it will be guided by the guide slope 140 under the Coanda effect. For example, when the air conditioner cabinet is operating in cooling mode, when the cold air is sent out through the air supply outlet 130, it will flow along the guide slope 140 toward the outer surface 120 of the air outlet panel 100, that is, the air flow will diffuse outward to the front surface of the air outlet panel 100 the moment it is sent out through the air supply outlet 130, so that the air outlet panel 100 can also blow cold air around the air supply outlet 130, and the cold air is used to isolate the air outlet panel 100 from the hotter air in the room to prevent condensation from forming around the air supply outlet 130.

[0029] It should be noted that, generally speaking, the 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. Specifically in this embodiment, the "front and back direction" of the air-conditioning cabinet can be Figure 1 and Figure 2 The arrows ab in the figure represent the “up and down directions” of the air conditioner cabinet. Figure 1 and Figure 2 The "direction of airflow through the air outlet 130" is the direction from the back of the air conditioner cabinet to the front, which is the direction indicated by arrow a; the "inner surface 110 of the air outlet panel 100" is the rearward-facing surface of the air outlet panel 100, and the "outer surface 120 of the air outlet panel 100" is the forward-facing surface of the air outlet panel 100.

[0030] Please continue to refer to Figure 4 In this embodiment, a straight guide section 150 can also be set at the edge of the air supply port 130, wherein the straight guide section 150 is set around the air supply port 130, and the straight guide section 150 extends along the direction of the air flow passing through the air supply port 130, and the air supply port 130 is connected to the guide slope 140 through the straight guide section 150.

[0031] When the air conditioner cabinet is in operation, the air flow is first guided by the straight guide section 150 in the process of flowing from the back to the front toward the air supply port 130, that is, when the air flow passes through the straight guide section 150, it will continue to flow forward in the original flow direction; when the air flow completely leaves the straight guide section 150, it will diffuse outward to the outer surface 120 of the air outlet panel 100 under the guidance of the guide slope 140, that is, diffuse to the front surface of the air outlet panel 100, thereby achieving isolation from the hotter air in the room, and further achieving the purpose of preventing condensation.

[0032] The arrangement of the above-mentioned straight guide section 150 allows the airflow to continue to flow along the original path at the moment it enters the air outlet 130, thereby avoiding the impact noise and turbulence caused by the airflow turning at an excessively large angle at the moment it enters the air outlet 130, and ensuring the stability of the airflow.

[0033] Please continue to refer to Figure 4 In this embodiment, the guide slope 140 is a plane.

[0034] This arrangement of the guide slope 140 facilitates processing and manufacturing.

[0035] Please continue to refer to Figure 4 In this embodiment, the angle between the guide slope 140 and the radial cross section of the air outlet 130 is α, wherein 40°<α<60°.

[0036] By limiting the angle α between the guide slope 140 and the radial cross-section of the air outlet 130 within the above-mentioned angle range, on the one hand, it can avoid the situation where the airflow is mostly guided to the outer surface 120 of the air outlet panel 100 due to α being too small, resulting in a reduction in the amount of air blown into the room. On the other hand, it can also avoid the situation where the airflow cannot be guided to the outer surface 120 of the air outlet panel 100 due to α being too large, thereby causing the anti-condensation effect to deteriorate.

[0037] Please continue to refer to Figure 4 In this embodiment, the guide slope 140 is formed by chamfering the edge of the air outlet 130 of the air outlet panel 100.

[0038] This form of forming the guide slope 140 on the air outlet panel 100 using a chamfering process allows the straight guide section 150 to be processed simultaneously, and the parts where the straight guide section 150 and the guide slope 140 are located are both solid structures with a certain thickness. While improving production efficiency, it also ensures the structural stability of the straight guide section 150 and the guide slope 140 and reduces deformation of the straight guide section 150 and the guide slope 140.

[0039] Please continue to refer to Figure 4 In this embodiment, a transition fillet 160 is provided between the guide slope 140 and the outer surface 120 .

[0040] By setting a transition radius 160 between the guide slope 140 and the outer surface 120, on the one hand, it can avoid the situation where the user's hands are scratched due to the sharp connection between the guide slope 140 and the outer surface 120, and on the other hand, it also makes the edge of the air outlet 130 look more rounded.

[0041] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the air outlet 130 is circular.

[0042] By setting the air outlet 130 to be circular, the processing stress at the edge of the air outlet 130 can be reduced while ensuring the air output.

[0043] Please continue to refer to Figure 1 and Figure 2 In this embodiment, there are two air outlets 130 , and the two air outlets 130 are arranged at intervals in the vertical direction.

[0044] By setting the number of air outlets 130 to two and arranging them at intervals in the up and down directions, not only can the air outlet area of ​​the air-conditioning cabinet be increased in the height direction to ensure the air outlet volume of the air-conditioning cabinet, but also the air-conditioning cabinet will not be too high, avoiding the risk of tipping over due to the increased center of gravity of the air-conditioning cabinet.

[0045] In other embodiments, the air outlets 130 may be provided in other numbers and arrangements, which are not limited in this embodiment.

[0046] Please continue to refer to Figures 1 to 3 In this embodiment, the air supply port 130 is provided with an air sweeping assembly 200 , wherein the air sweeping assembly 200 has a closing position for closing the air supply port 130 and an air guiding position for at least partially exposing the air supply port 130 .

[0047] When the air-conditioning cabinet is in operation, when an air-guiding operation is required, the air-sweeping component 200 can be switched to the air-guiding position to at least partially expose the air supply port 130, so that the air-conditioning air can be blown into the indoor space through the air supply port 130; when the air-conditioning cabinet is in shutdown state, the air-sweeping component 200 can be switched to the closed position to close the air supply port 130, so as to achieve shielding of the air supply port 130.

[0048] The air-conditioning cabinet can not only use the action of the wind sweeping component 200 to guide the air in the running state to meet the multi-angle air supply requirements of the air-conditioning cabinet, but also use the wind sweeping component 200 to block the air supply port 130 in the shutdown state to achieve the purpose of closing the air supply port 130. There is no need to set up a sliding panel for closing the air supply port 130, thereby effectively simplifying the structure of the air-conditioning cabinet.

[0049] Please continue to refer to Figures 1 to 4 In this embodiment, the air sweeping assembly 200 may include a plurality of air sweeping blades 210 arranged in the up and down directions. Specifically, the plurality of air sweeping blades 210 are rotatably connected to the air outlet panel 100, and a stop sealing structure 220 is provided between any two adjacent air sweeping blades 210, wherein the stop sealing structure 220 is used to make any two adjacent air sweeping blades 210 overlap and fit in the closed position.

[0050] The setting of the above-mentioned stop sealing structure 220 ensures that when the air sweeping assembly 200 is in the closed position, the gap between any two adjacent blades is blocked, effectively preventing impurities from entering the inner cavity of the air-conditioning cabinet when it is shut down, and ensuring the neatness of the external structure of the air-conditioning cabinet.

[0051] Please continue to refer to Figure 4 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 sweeping blade 210, and is located on the side of the sweeping blade 210 facing the inner cavity of the air-conditioning cabinet in the closed position, and the first inclined surface 221 extends obliquely from bottom to top toward the direction close to the inner cavity; the second inclined surface 222 is arranged on the lower sweeping blade 210, and is located on the side of the sweeping blade 210 facing away from the inner cavity of the air-conditioning cabinet in the closed position, and the second inclined surface 222 extends obliquely from bottom to top toward the direction close to the inner cavity.

[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 sweeping blades 210 is reliably closed in the closed position, and also enables the air-conditioning wind to be guided along the first bevel 221 and the second bevel 222 when the sweeping blade 210 is in the wind-guiding position, thereby achieving the guidance of the air-conditioning wind at the edge position of the sweeping blade 210, so as to reduce the eddy current and noise of the air-conditioning wind at the edge position of the sweeping blade 210.

[0053] Please continue to refer to Figure 1 and Figure 3 In this embodiment, an air supply assembly 300 is provided at the position of the air supply outlet 130. Specifically, the air supply assembly 300 includes a drive motor 310 and an air supply impeller 320. The body of the drive motor 310 is fixedly arranged relative to the air outlet panel 100. The motor shaft of the drive motor 310 extends in the front-to-back direction. The air supply impeller 320 is fixedly mounted on the motor shaft, and the air supply impeller 320 is opposite to the air supply outlet 130.

[0054] When the cabinet air conditioner is in operation, the drive motor 310 is activated, driving the air supply impeller 320 to rotate. The rotation of the air supply impeller 320 causes external air to enter the inner cavity and be discharged into the indoor space through the air supply port 130. This arrangement of the air supply assembly 300 has a simple structure and helps reduce the front-to-back dimensions of the cabinet air conditioner, facilitating a thinner design for the cabinet air conditioner.
