Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning distributor structure and an air conditioning unit. Background Technology

[0002] To meet the increasing demand for airflow in passenger spaces, automotive air conditioning units need to achieve complex airflow distribution within a limited space. Currently, a distributor is typically used to distribute airflow from a single path to multiple ducts via a single damper. Specifically, rotating the damper connects the air intake duct to the face-blowing duct for face-blowing mode; connects the air intake duct to the foot-blowing duct for foot-blowing mode; connects the air intake duct to both the face-blowing and foot-blowing ducts for face-blowing and foot-blowing mode; and disconnects the air intake duct from both the face-blowing and foot-blowing ducts, but connects it to the defrost vent for defrosting mode, etc.

[0003] However, the existing air distributors have poor damper sealing, for example, air leakage and cross-flow occur in the face blowing mode.

[0004] Therefore, there is an urgent need to propose an air conditioning distributor structure and an air conditioning unit to solve the above problems. Utility Model Content

[0005] The first objective of this utility model is to provide an air conditioner distributor structure that can improve the user experience in the air conditioner unit's face-blowing operation mode and also prevent airflow from entering the air conditioner unit during the defrost face-blowing operation mode.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The structure of an air conditioning distributor includes:

[0008] The shell body has an air inlet, a face outlet, and a foot outlet circumferentially arranged along the side wall of the shell body;

[0009] The first protrusion and the second protrusion are both protruding on the inner side wall of the shell body. Along the inner side wall of the shell body, the first protrusion is located on the side edge of the blowing port facing the foot blowing port, and the second protrusion is located on the side edge of the air inlet facing the foot blowing port.

[0010] The first cut-off surface baffle is fixed to the inner wall of the shell body. The first cut-off surface baffle extends radially toward the blowing port of the shell body to divide the blowing port. The end of the first cut-off surface baffle is provided with an extension portion, which extends from the blowing port to the blowing channel.

[0011] A damper is rotatably disposed within the shell, and the damper includes a first blade and a second blade, with a first end and a second end respectively provided on the first blade and the second blade.

[0012] When the first blade and the second blade rotate to the first boss and the second boss respectively, the first end and the second end can respectively abut and deform with the first boss and the second boss, and form an interference fit; when the first blade rotates to the stop rib of the first cut-off surface, the first end can abut and seal with the extension.

[0013] As an optional technical solution for the air conditioner distributor structure, the air conditioner distributor structure further includes a second stop surface baffle. The second stop surface baffle is fixed to the inner wall of the shell body and is located on the side of the second protrusion facing the air outlet, so that when the first blade abuts and seals with the first stop surface baffle, the second blade abuts and seals with the second stop surface baffle.

[0014] As an optional technical solution for the structure of an air conditioner distributor, the ends of the first and second cut-off surface baffles are respectively provided with a first cut-off straight stop and a second cut-off straight stop, and the first and second cut-off straight stops both extend beyond the first and second cut-off surface baffles along the axial direction of the shell body. The extension is connected to the first cut-off straight stop, and the first end and the second end can respectively abut against and deform with the first and second cut-off straight stops.

[0015] As an optional technical solution for the structure of an air conditioning distributor, the extension and the first cut-off straight section are integrally formed.

[0016] As an optional technical solution for the air conditioner distributor structure, the air conditioner distributor structure further includes a third cut-off surface baffle and a fourth cut-off surface baffle fixed to the inner wall of the shell. The third cut-off surface baffle is located between the air inlet and the foot outlet on the side facing the foot outlet, and the fourth cut-off surface baffle is located on the side of the first cut-off surface baffle facing the air inlet. When the first blade abuts and seals with the third cut-off surface baffle, the second blade abuts and seals with the fourth cut-off surface baffle.

[0017] As an optional technical solution for the structure of an air conditioner distributor, the ends of the third and fourth cut-off surface baffles are respectively provided with a third cut-off straight baffle and a fourth cut-off straight baffle, and the third and fourth cut-off straight baffles both extend beyond the third and fourth cut-off surface baffles along the axial direction of the shell body. The first end and the second end can respectively abut and deform with the third and fourth cut-off straight baffles.

[0018] As an optional technical solution for the structure of an air conditioner distributor, the outer sides of the first blade and the second blade are covered with soft rubber.

[0019] As an optional technical solution for the structure of an air conditioner distributor, the soft rubber at the first end and the second end is Y-shaped, with the opening of the Y-shape facing the inner wall of the shell body respectively.

[0020] As an optional technical solution for the structure of an air conditioner distributor, the soft rubber coating on both sides of the first blade and the second blade is Y-shaped, and the opening of the Y-shape faces the inner wall of the shell body respectively.

[0021] The second objective of this utility model is to provide an air conditioning unit that can operate in six working modes, has multiple system functions, and provides a good air blowing experience.

[0022] To achieve this objective, the present invention adopts the following technical solution:

[0023] An air conditioning unit includes a defrost port and the aforementioned air conditioning distributor structure, wherein the defrost port is connected to the air inlet.

[0024] The beneficial effects of this utility model are:

[0025] The air conditioner distributor structure provided by this utility model includes a shell body, a first boss, a second boss, a first stop surface baffle, and an air damper. The side wall of the shell body is circumferentially provided with an air inlet, a face inlet, and a foot inlet. The air damper is rotatably disposed within the shell body and includes a first blade and a second blade. By rotating the air damper to different positions, the air inlet can be connected to or disconnected from the face inlet and / or foot inlet, realizing different operating modes of the air conditioning unit. For example, when the air inlet is only connected to the face inlet, a face-blowing operating mode is achieved; when the air inlet is connected to both the face inlet and the foot inlet, a face-blowing and foot-blowing operating mode is achieved; when the air inlet is only connected to the foot inlet, a foot-blowing operating mode is achieved; when the air inlet is not connected to either the face inlet or the foot inlet, the air damper is in a fully closed state. If the air inlet is connected to the defrost inlet at this time, a defrost operating mode is achieved. This air conditioner distributor structure can also connect the air inlet and the defrost outlet for defrosting, while the face outlet or foot outlet only maintains a certain opening to connect with the air inlet, realizing a defrost face outlet working mode or a defrost foot outlet working mode, increasing the air outlet working modes of the air conditioning unit and improving the air blowing experience.

[0026] Both the first and second protrusions are protruding from the inner wall of the shell. When the first blade and the second blade rotate to the first and second protrusions respectively, the first end and the second end can respectively abut and deform with the first and second protrusions, forming an interference fit. That is, the air inlet is only connected to the blowing port. The design of the first and second protrusions ensures the sealing of the air damper in the blowing mode of the air conditioning unit, avoids air leakage, and improves the blowing experience. At the same time, the deformation of the first and second ends allows the damper to rotate normally and will not stop due to obstruction of the rotation of the damper. Thus, the damper can pass smoothly through the first and second protrusions, ensuring smooth airflow. Secondly, the first cut-off surface baffle is fixed to the inner wall of the shell body. The first cut-off surface baffle extends towards the blowing port to divide the blowing port, so that when the first blade rotates to the first cut-off surface baffle, the blowing port maintains a small opening, and only a small amount of air is blown out from the blowing port. The end of the first cut-off surface baffle is provided with an extension, which extends from the blowing port to the blowing channel, so that when the first blade rotates to the first cut-off surface baffle, the first end can abut against the extension and seal, increasing the sealing performance of the damper. The damper can also smoothly rotate back to the various working mode positions it has passed through before, and avoid unnecessary air leakage while meeting the requirements of air volume distribution.

[0040] This embodiment provides an air conditioner distributor structure that can improve the user experience in the air conditioner unit's face-blowing mode and also prevent airflow from entering the air conditioner unit during the defrost face-blowing mode.

[0041] Specifically, such as Figures 1 to 7 As shown, the air conditioner distributor structure includes a shell body 100, a first boss 111, a second boss 112, a first cut-off surface baffle 121, and an air damper. An air inlet, a surface inlet, and a foot inlet are provided circumferentially along the side wall of the shell body 100. Both the first boss 111 and the second boss 112 protrude from the inner side wall of the shell body 100. Along the inner side wall of the shell body 100, the first boss 111 is located on the edge of the surface inlet facing the foot inlet, and the second boss 112 is located on the edge of the air inlet facing the foot inlet. The first cut-off surface baffle 121 is fixed to the inner wall of the shell body 100. The first cut-off surface baffle 121 extends radially along the shell body 100 towards the surface inlet to divide it. The end of the first cut-off surface baffle 121 has an extension 123 that extends from the surface inlet into the surface flow channel 320. The damper is rotatably mounted inside the shell 100 about the central axis of the shell 100. The damper includes a first blade 210 and a second blade 220. The first blade 210 and the second blade 220 are respectively provided with a first end and a second end. The first end is located on the side of the first blade 210 facing the shell 100, and the second end is located on the side of the second blade 220 facing the shell 100. When the first end and the second end are not at the air inlet, face outlet, or foot outlet, they abut against the inner wall of the shell 100. In actual operation, when the first blade 210 and the second blade 220 rotate to the first boss 111 and the second boss 112 respectively, the first end and the second end can abut against the first boss 111 and the second boss 112 respectively and deform, forming an interference fit; when the first blade 210 rotates to the first stop surface baffle 121, the first end can abut against the extension 123 and seal.

[0042] It is worth noting that in this embodiment, the air inlet, face blowing inlet, and foot blowing inlet are arranged in a clockwise direction at intervals; and the air inlet is connected to the air inlet channel 310, the face blowing inlet is connected to the face blowing channel 320, and the foot blowing inlet is connected to the foot blowing channel 330. That is, the air from the air inlet is blown in through the air inlet channel 310, the air from the face blowing inlet is blown towards the human face through the face blowing channel 320, and the air from the foot blowing inlet is blown towards the human feet through the foot blowing channel 330.

[0043] Based on the above design, the side wall of the shell 100 is circumferentially provided with an air inlet, a face inlet, and a foot inlet. The damper is rotatably disposed inside the shell 100. The damper includes a first blade 210 and a second blade 220. By rotating the damper to different positions, the air inlet can be connected to or disconnected from the face inlet and / or the foot inlet, thereby realizing different working modes of the air conditioning unit. For example, when the air inlet is only connected to the face inlet, the face blowing working mode is realized; when the air inlet is connected to both the face inlet and the foot inlet, the foot blowing and face blowing working mode (also called face blowing and foot blowing working mode) is realized; when the air inlet is only connected to the foot inlet, the foot blowing working mode is realized; when the air inlet is not connected to either the face inlet or the foot inlet, the damper is in a fully closed state. If the air inlet is connected to the defrost inlet at this time, the defrost working mode is realized. This air conditioner distributor structure can also connect the air inlet and the defrost outlet for defrosting, while the face outlet or foot outlet only maintains a certain opening to connect with the air inlet, realizing a defrost face outlet working mode or a defrost foot outlet working mode, increasing the air outlet working modes of the air conditioning unit and improving the air blowing experience.

[0044] The first protrusion 111 and the second protrusion 112 are both protruding from the inner wall of the shell body 100. When the first blade 210 and the second blade 220 rotate to the first protrusion 111 and the second protrusion 112 respectively, the first end and the second end can respectively abut and deform with the first protrusion 111 and the second protrusion 112, and form an interference fit. That is, the air inlet is only connected to the blowing port. The design of the first protrusion 111 and the second protrusion 112 ensures the sealing of the air damper in the blowing mode of the air conditioning unit, avoids air leakage, and improves the blowing experience. At the same time, the deformation of the first end of the first blade 210 and the second end of the second blade 220 allows the damper to rotate normally and will not stop due to the obstruction of the rotation of the damper. Thus, the first blade 210 and the second blade 220 of the damper can pass smoothly through the first protrusion 111 and the second protrusion 112, ensuring smooth airflow. Secondly, the first cut-off surface baffle 121 is fixed to the inner wall of the shell body 100. The first cut-off surface baffle 121 extends towards the blowing port to divide the blowing port, so that when the first blade 210 rotates to the first cut-off surface baffle 121, the blowing port maintains a small opening, and only a small amount of air is blown out from the blowing port. The end of the first cut-off surface baffle 121 is provided with an extension 123. The extension 123 extends from the blowing port to the blowing channel 320, so that when the first blade 210 rotates to the first cut-off surface baffle 121, the first end can abut against the extension 123 to seal, increasing the sealing performance of the damper. The damper can also smoothly rotate back to the various working mode positions it has passed through before, avoiding unnecessary air leakage while meeting the requirements of air volume distribution.

[0045] To achieve the above-mentioned blowing operation mode, continue as follows: Figure 1 and Figure 6As shown, the air conditioner distributor structure also includes a fifth cut-off surface baffle 141 and a sixth cut-off surface baffle 142. The fifth cut-off surface baffle 141 and the sixth cut-off surface baffle 142 are respectively connected to the first boss 111 and the second boss 112, so that the side wall of the first blade 210 and the side wall of the second blade 220 can respectively abut and seal with the fifth cut-off surface baffle 141 and the sixth cut-off surface baffle 142. The fifth cut-off surface baffle 141, the first boss 111, the sixth cut-off surface baffle 142 and the second boss 112 form a complete cut-off surface baffle protrusion structure, realizing the complete sealing of the damper and preventing air from running towards the foot outlet.

[0046] To achieve the above defrosting and blowing operation mode, continue as follows: Figure 1 and Figure 7 As shown, the air conditioner distributor structure also includes a second cut-off surface baffle 122. The second cut-off surface baffle 122 is fixed to the inner wall of the shell 100 and is located on the side of the second protrusion 112 facing the foot outlet. When the first blade 210 abuts and seals with the first cut-off surface baffle 121, the second blade 220 abuts and seals with the second cut-off surface baffle 122. The first cut-off surface baffle 121 and the second cut-off surface baffle 122 work together to ensure that the air inlet is only connected to the air outlet, preventing air from flowing towards the foot outlet while defrosting the air outlet.

[0047] Furthermore, the ends of the first stop surface baffle 121 and the second stop surface baffle 122 are respectively provided with a first stop straight baffle 124 and a second stop straight baffle 125, and the first stop straight baffle 124 and the second stop straight baffle 125 both extend beyond the first stop surface baffle 121 and the second stop surface baffle 122 along the axial direction of the shell body 100. The extension portion 123 is connected to the first stop straight baffle 124, and the first end and the second end can respectively abut and deform with the first stop straight baffle 124 and the second stop straight baffle 125, that is, increase the end area of ​​the first stop surface baffle 121 and the second stop surface baffle 122, increase the contact area between the end of the first stop surface baffle 121 and the end of the second stop surface baffle 122 and the first end of the first blade 210 and the second end of the second blade 220, realize the end abutment seal of the first end and the second end, and increase the sealing performance of the damper.

[0048] Furthermore, the extension 123 and the first stop straight section 124 are integrally formed, meaning that the extension 123 is actually an extension of the first stop straight section 124, which simplifies the manufacturing process.

[0049] Optionally, to achieve the above defrosting working mode, continue as follows: Figure 1 and Figure 2As shown, the air conditioner distributor structure also includes a third cut-off surface baffle 131 and a fourth cut-off surface baffle 132 fixed to the inner wall of the shell body 100. The third cut-off surface baffle 131 is located between the air inlet and the foot outlet on the side facing the foot outlet, and the fourth cut-off surface baffle 132 is located on the side of the first cut-off surface baffle 121 facing the air inlet. When the first blade 210 abuts and seals with the third cut-off surface baffle 131, the second blade 220 can abut and seal with the fourth cut-off surface baffle 132, so that the air inlet is not connected to the face outlet and the foot outlet, that is, the damper is fully closed. When the air inlet is connected to the defrost outlet, the defrost working mode is realized.

[0050] Furthermore, the ends of the third stop surface baffle 131 and the fourth stop surface baffle 132 are respectively provided with a third stop straight stop and a fourth stop straight stop, and the third stop straight stop and the fourth stop straight stop both extend beyond the third stop surface baffle 131 and the fourth stop surface baffle 132 along the axial direction of the shell body 100. The first end and the second end can respectively abut and deform with the third stop straight stop and the fourth stop straight stop, and their functions are similar to those of the first stop straight stop 124 and the second stop straight stop 125, so as to achieve end abutment sealing of the first end and the second end, increase the sealing performance of the damper, and ensure the fully closed state of the damper.

[0051] In the above defrosting and foot-blowing working mode, continue as follows Figure 1 and Figure 3 As shown, the second end of the second blade 220 is located on the side of the fourth cut-off surface baffle 132 facing the air inlet (away from the first cut-off surface baffle 121) and abuts against the inner wall of the shell body 100. The first end of the first blade 210 is located at the foot outlet, so that the foot outlet has a certain opening and is connected to the air inlet. While defrosting, a certain amount of foot blowing can be performed to improve the blowing experience.

[0052] In the above foot blowing working mode, continue as follows Figure 4 As shown, the first end of the first blade 210 is located on the side of the foot-blowing opening facing the first cut-off surface baffle 121, meaning the foot-blowing opening is fully open. The second end of the second blade 220 is located on the side of the air inlet facing the first cut-off surface baffle 121, making the air inlet and the foot-blowing opening completely connected. In this working mode, since there is no sealing of the cut-off surface baffle structure, most of the air enters the foot-blowing opening, but the damper will guide a small portion of the airflow to the face-blowing opening (not shown in the figure).

[0053] In the above-mentioned foot and face blowing working mode, continue as follows Figure 5 As shown, the first end of the first blade 210 abuts against the inner wall of the shell 100 between the face blowing port and the foot blowing port, and the second end of the second blade 220 is located at the air inlet, so that the air inlet is connected to both the face blowing port and the foot blowing port. The damper rotates to change the opening distribution of the air inlet to the face blowing port and the foot blowing port, thereby adjusting the air volume distribution of the face blowing and foot blowing ports.

[0054] Optionally, the outer sides of the first blade 210 and the second blade 220 are covered with soft rubber, which enables the sidewalls of the first blade 210 and the second blade 220 to abut against and deform with the first stop surface baffle 121 and the second stop surface baffle 122, or the third stop surface baffle 131 and the fourth stop surface baffle 132, respectively; at the same time, the first end and the second end abut against and deform with the first stop straight baffle 124 and the second stop straight baffle 125, or the third stop straight baffle and the fourth stop straight baffle, respectively.

[0055] Specifically, the soft rubber coating at the first and second ends is Y-shaped, with the opening of the Y-shape facing the inner wall of the shell 100, and the end of the Y-shape is convenient to pass through the first stop bar 124, the second stop bar 125, the third stop bar, or the fourth stop bar.

[0056] Similarly, the soft rubber coating on both sides of the first blade 210 and the second blade 220 is Y-shaped, with the opening of the Y-shape facing the inner wall of the shell 100 respectively.

[0057] Typically, the first blade 210 and the second blade are rectangular structures, with a soft coating covering the outside of the rectangular structure to form a rectangular soft coating. The aforementioned Y-shaped soft coating structure can be understood as having a V-shaped groove on the peripheral wall of the rectangular soft coating (excluding the side facing the damper shaft).

[0058] This embodiment also provides an air conditioning unit that can operate in six working modes, has multiple system functions, and provides a good air blowing experience.

[0059] Specifically, the air conditioning unit includes a defrost port (not shown in the figure) and the aforementioned air conditioning distributor structure, with the defrost port connected to the air inlet. The design of the first protrusion 111 and the second protrusion 112 ensures the airtightness of the air damper in the air conditioning unit's face-blowing operation mode, preventing air leakage and improving the face-blowing experience; at the same time, the deformation of the first and second ends allows the damper to rotate normally without stopping due to obstruction of the damper's rotation, thus allowing the damper to pass smoothly through the first protrusion 111 and the second protrusion 112, ensuring unobstructed airflow. Secondly, the first cut-off surface baffle 121 is fixed to the inner wall of the shell body 100. The first cut-off surface baffle 121 extends towards the blowing port to divide the blowing port, so that the blowing port maintains a small opening and only a small amount of air is blown out from the blowing port. The end of the first cut-off surface baffle 121 is provided with an extension 123. The extension 123 extends from the blowing port to the blowing channel 320. When the first blade 210 rotates to the first cut-off surface baffle 121, the first end can abut against the extension 123 to seal, increasing the sealing performance of the damper. The damper can smoothly rotate back to the various working mode positions it has passed through before, and avoid unnecessary air leakage while meeting the requirements of air volume distribution.

[0060] Figures 2 to 7This is a diagram showing the state of the air conditioner distributor structure as the damper rotates counterclockwise, sequentially operating in defrost mode, defrost foot blowing mode, foot blowing mode, foot blowing face mode, face blowing mode, and defrost face blowing mode. The arrows in the diagram indicate the main airflow direction.

[0061] Specifically, such as Figure 2 As shown, in the defrosting mode, also known as the fully closed damper mode, the sidewalls of the first blade 210 and the second blade 220 of the damper abut against the third cutoff surface baffle 131 and the fourth cutoff surface baffle 132, respectively. The first end of the first blade 210 and the second end of the second blade 220 abut against and deform against the third cutoff straight stop and the fourth cutoff straight stop, respectively. The third cutoff surface baffle 131, the fourth cutoff surface baffle 132, the third cutoff straight stop, and the fourth cutoff straight stop form a complete cutoff surface baffle structure. When the damper is fully closed, it is sealed by this complete cutoff surface baffle structure to ensure that the airflow does not leak, thereby improving the system energy efficiency of the air conditioning unit.

[0062] like Figure 3 As shown, when the damper rotates counterclockwise, the first blade 210 disengages from the third cutoff surface baffle 131, and its first end detaches from the inner wall of the shell 100 and enters the foot blower inlet, giving the foot blower inlet a certain opening. A small amount of air can then be blown out from the foot blower inlet, achieving defrosting while simultaneously blowing air into the feet—this is the defrosting and foot blowing working mode. In this working mode, the damper can be rotated to change the opening of the foot blower inlet, thus changing the amount of air blown into the foot blower inlet.

[0063] like Figure 4 As shown, the damper continues to rotate counterclockwise, and the first end of the first blade 210 moves away from the foot-blowing port and re-abuts against the inner wall of the shell 100. At this time, the foot-blowing port is fully open, realizing the foot-blowing working mode.

[0064] It should be noted that at this time, since the sealing of the stop surface baffle structure is completely released, most of the air enters the foot inlet, but the damper will guide a small portion of the air volume to the face inlet (this situation is not shown in the figure).

[0065] like Figure 5 As shown, the damper continues to rotate counterclockwise. The first end of the first blade 210 abuts against the inner wall of the shell 100 between the face blowing port and the foot blowing port. The second end of the second blade 220 is located at the air inlet, so that the air inlet is connected to both the face blowing port and the foot blowing port, realizing the foot blowing and face blowing working mode. The rotation of the damper changes the opening distribution of the air inlet to the face blowing port and the foot blowing port, and adjusts the air volume distribution of the face blowing and foot blowing.

[0066] like Figure 6As shown, the damper continues to rotate counterclockwise. The Y-shaped soft rubber on the first end abuts and deforms to seal against the first boss 111, and the Y-shaped soft rubber on the second end abuts and deforms to seal against the second boss 112. Of course, the soft rubber on the sidewalls of the first blade 210 and the second blade 220 abuts against the fifth stop surface baffle 141 and the sixth stop surface baffle 142 on the shell body 100, respectively, ensuring that the air inlet only connects to the blowing port, thus achieving the blowing operation mode. Through the protruding structure design of the first boss 111 and the second boss 112, the damper forms an interference fit between the soft rubber and the protruding structure, effectively ensuring the damper's sealing performance while allowing normal rotation without stagnation due to obstructed rotation. Through the slight deformation of the soft rubber, the damper can smoothly pass through the protruding structure, ensuring unobstructed airflow.

[0067] like Figure 7 As shown above, the damper can continue to rotate counterclockwise. The soft rubber coating on the side walls of the first blade 210 and the second blade 220 will respectively abut against the first stop surface baffle 121 and the second stop surface baffle 122 on the shell body 100. Since the first stop straight baffle 124 and the extension 123 can sufficiently block the wind from entering the foot outlet from the first end, the damper's sealing performance is increased. The damper can smoothly rotate back to the various working mode positions it has passed through before, thus avoiding unnecessary air leakage while meeting the air volume distribution requirements.
