Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to an exhaust pipe connector and an air conditioner. Background Technology

[0002] In related technologies, integrated air conditioners, such as kitchen air conditioners, consist of an indoor unit and an outdoor unit, with the entire unit installed inside the ceiling on the indoor side. During installation, an exhaust duct connector needs to be installed on the air conditioner unit, and then an exhaust duct is installed on the connector, extending to the outdoor side and connecting to the outside air. The air conditioner works by having ambient temperature air from the indoor side enter the evaporator on the indoor unit, exchange heat, and become cold air, which is then blown out from the air outlet on the air conditioner panel to cool the indoor area. Simultaneously, ambient temperature air from the indoor side enters the condenser on the outdoor unit, exchange heat, and becomes hotter air, which is then exhausted to the outside through the exhaust duct.

[0003] Because the exhaust duct connects the outdoor unit to the air conditioning unit, outdoor air can enter the unit. If the air conditioning unit is installed in a low-temperature environment in northern regions, and is turned off when not in use, cold outdoor air will still enter through the exhaust duct. Due to the temperature difference between the indoor and outdoor units, condensation will form inside the unit. This condensation will gradually accumulate and drip from the air conditioning panel, leading to customer complaints and damaging the product's reputation. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an exhaust pipe connector that can prevent cold outdoor air from entering the air conditioner and forming condensation in low-temperature environments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0075] The exhaust pipe connector 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The exhaust pipe connector 10 is used in an air conditioner 100, which has an outdoor exhaust port 201 adapted to communicate with the outdoor environment, and the exhaust pipe connector 10 is located at the outdoor exhaust port 201.

[0076] Specifically, such as Figures 1-9 As shown, the air conditioner 100 can be an integrated air conditioner, such as a kitchen air conditioner. The air conditioner 100 includes a housing 20, which has an indoor heat exchange duct 203 and an outdoor heat exchange duct 204. The outdoor exhaust vent 201 is connected to the outdoor heat exchange duct 204. The housing 20 also has an indoor air inlet and an indoor air outlet connected to the indoor heat exchange duct 203, and an outdoor air inlet connected to the outdoor heat exchange duct 204. The indoor air inlet, indoor air outlet and outdoor air inlet are connected to the indoor environment.

[0077] In addition, the air conditioner 100 also includes an indoor fan, an indoor heat exchanger, an outdoor fan, and an outdoor heat exchanger. The indoor fan and the indoor heat exchanger are located in the indoor heat exchange duct 203, and the outdoor fan and the outdoor heat exchanger are located in the outdoor heat exchange duct 204. The indoor fan is used to drive the airflow from the indoor air inlet to the indoor air outlet, and the indoor heat exchanger is used to exchange heat with the airflow entering the indoor heat exchange duct 203. The outdoor fan is used to drive the airflow from the outdoor air inlet to the outdoor air outlet 201, and the outdoor heat exchanger is used to exchange heat with the airflow entering the outdoor heat exchange duct 204.

[0078] like Figures 15-18 , Figures 21-24 As shown, the exhaust pipe connector 10 according to an embodiment of the present invention includes a connector body 1 and a valve plate 2.

[0079] Specifically, the connector body 1 has a connecting channel 11, one end of which is connected to the outdoor exhaust vent 201, and the other end is adapted to connect to the outdoor environment. A valve plate 2 is rotatably disposed within the connecting channel 11 and is used to open or close the connecting channel 11. The valve plate 2 can be rotated as needed, thereby enabling the outdoor exhaust vent 201 to connect to or disconnect from the outdoor environment through the rotation of the valve plate 2.

[0080] For example, the valve plate 2 on the exhaust pipe connector 10 opens or closes according to the operating status of the air conditioner 100. When the air conditioner 100 is on, the valve plate 2 opens the connecting channel 11, connecting the indoor and outdoor sides of the exhaust pipe connector 10, facilitating the airflow after heat exchange with the outdoor heat exchanger to be discharged outdoors through the exhaust pipe connector 10. When the air conditioner 100 is off, the valve plate 2 closes the connecting channel 11, closing the exhaust pipe connector 10 and isolating the indoor and outdoor air. In low-temperature environments, this prevents cold outdoor air from entering the air conditioner 100 and forming condensation, avoiding the quality risk of water dripping from the air conditioner panel 40, preventing user complaints, and improving product reliability and user experience.

[0081] In addition, when the air conditioner 100 is not turned on, that is, when the user is not using the air conditioner 100, the valve plate 2 on the exhaust pipe connector 10 is in a closed state, isolating the outdoor side and the indoor side of the exhaust pipe connector 10. This also prevents foreign objects such as fallen leaves, dust, rats, cockroaches, mosquitoes, etc. from the outdoor side from entering the air conditioner 100 through the exhaust pipe connector 10, thus protecting the air conditioner 100 and the indoor environment.

[0082] According to an embodiment of this utility model, the exhaust pipe connector 10 is located at the outdoor exhaust port 201 of the air conditioner 100. A rotatable valve plate 2 is installed inside the connector body 1. The valve plate 2 is used to open or close the connecting channel 11 of the connector body 1, thereby allowing the indoor and outdoor sides of the exhaust pipe connector 10 to be connected or isolated as needed. Specifically, when the air conditioner 100 is turned on, the valve plate 2 can open the connecting channel 11, connecting the indoor and outdoor sides of the exhaust pipe connector 10, allowing airflow inside the air conditioner 100 to be discharged through the outdoor exhaust port 201. When the air conditioner 100 is turned off, the valve plate 2 can close the connecting channel 11, isolating the indoor and outdoor sides of the exhaust pipe connector 10. In low-temperature environments, this prevents cold air from the outdoor side from entering the air conditioner 100 and forming condensation, avoiding the quality risk of water dripping from the air conditioner panel 40, preventing user complaints, and improving product reliability and user experience. Furthermore, it prevents debris, insects, and other contaminants from entering the air conditioner 100, protecting the air conditioner 100 and the indoor environment.

[0083] In some embodiments of this utility model, such as Figure 25 , Figure 27 ,refer to Figures 32-34The valve plate 2 includes a rotating shaft 21 and a first valve plate 22 and a second valve plate 23 disposed on opposite sides of the rotating shaft 21. The rotating shaft 21 is rotatably mounted on the connector body 1. It can be understood that the rotating shaft 21 of the valve plate 2 is located in the middle area of ​​the valve plate 2, which facilitates the rotation of the valve plate 2 within the connecting channel 11 and allows the valve plate 2 to increase its rotation angle, thereby increasing the maximum opening area of ​​the exhaust pipe connector 10, reducing the resistance to airflow discharge, increasing the exhaust volume, and improving the cooling and heating performance of the air conditioner 100.

[0084] In some embodiments of this utility model, the first valve plate 22 and the second valve plate 23 are symmetrically arranged about the axis of the rotating shaft 21. This maximizes the rotation angle of the valve plate 2. For example, when the valve plate 2 is in the closed position of the connecting channel 11, the angle is 0 degrees. The valve plate 2 can rotate 90 degrees to open the connecting channel 11. At this time, the rotatable angle of the valve plate 2 is 0 degrees to 90 degrees, maximizing the maximum opening area of ​​the exhaust pipe joint 10. This maximizes the opening area of ​​the exhaust pipe joint 10, reduces airflow resistance, increases exhaust volume, and improves the cooling and heating performance of the air conditioner 100. In addition, it simplifies the structure and processing technology of the valve plate 2 and improves production efficiency.

[0085] exist Figure 25 , Figure 27 and Figures 32-34 In the example shown, the cross-section of the connecting channel 11 is circular, the valve plate 2 is roughly circular, the rotating shaft 21 is located in the middle of the valve plate 2, the first valve plate 22 and the second valve plate 23 are symmetrically arranged and have a semi-circular structure, the rotating shaft 21 is rotatably connected to the connector body 1, which allows the valve plate 2 to rotate freely in the connecting channel 11, thereby allowing for more flexible adjustment of the opening area of ​​the exhaust pipe connector 10.

[0086] Of course, this utility model is not limited to this. The cross-sectional shape of the connecting channel 11 can be rectangular. The rotating shaft 21 extends along the length or width of the rectangular connecting channel 11. The valve plate 2 is rectangular. The rotating shaft 21 can be located in the middle of the valve plate 2. The first valve plate 22 and the second valve plate 23 are symmetrically arranged and are rectangular. This allows the valve plate 2 to rotate freely in the connecting channel 11, thereby allowing for more flexible adjustment of the opening area of ​​the exhaust pipe connector 10.

[0087] In some other embodiments of this utility model, the valve plate 2 includes a valve plate body and a rotating shaft 21. The rotating shaft 21 is located at one end of the valve plate body and is rotatably connected to the connector body 1. The end of the valve plate body facing away from the rotating shaft 21 rotates relative to the end of the valve plate body connected to the rotating shaft 21. In this case, the cross-sectional shape of the connecting channel 11 can be rectangular, the valve plate body can be rectangular, the rotating shaft 21 can be located at one end of the length direction of the valve plate body and extend along the width direction of the valve plate body, and the rotating shaft 21 can be located at one end of the length direction of the cross-section of the connecting channel 11 and extend along the width direction of the cross-section of the connecting channel 11.

[0088] In some embodiments of this utility model, such as Figures 32-34 As shown, the valve plate 2 is provided with a reinforcing protrusion 24. The reinforcing protrusion 24 is formed by a portion of the valve plate 2 protruding towards the thickness direction of the valve plate 2, thereby strengthening the structural strength of the valve plate 2 and improving the reliability of the valve plate 2's fixation. For example, in Figures 32-34 In the example shown, both the first valve plate 22 and the second valve plate 23 are provided with reinforcing protrusions 24. The reinforcing protrusions 24 are semicircles corresponding to the first valve plate 22 and the second valve plate 23. Along the circumferential direction of the valve plate 2, the distance between the reinforcing protrusions 24 and the edge of the valve plate 2 is the same.

[0089] Furthermore, such as Figures 32-34 As shown, both the first valve plate 22 and the second valve plate 23 are provided with reinforcing protrusions 24, and the protrusion directions of the reinforcing protrusions 24 on the first valve plate 22 and the second valve plate 23 are opposite.

[0090] In some embodiments of this utility model, such as Figures 18-20 , Figure 21 , Figure 25 , Figure 27 , Figures 29-31 As shown, the inner circumferential wall of the connecting channel 11 is provided with a first sealing rib 17 and a second sealing rib 18. The first sealing rib 17 and the second sealing rib 18 are located on opposite sides of the axis of the rotating shaft 21 and extend along the circumferential direction of the connecting channel 11. When the valve plate 2 closes the connecting channel 11, the first sealing rib 17 and the second sealing rib 18 are located on opposite sides of the thickness direction of the valve plate 2. The first valve plate 22 abuts against the first sealing rib 17, and the second valve plate 23 abuts against the second sealing rib 18.

[0091] When valve plate 2 closes the connecting channel 11, the side of valve plate 2 facing the outdoor exhaust port 201 in the thickness direction is the indoor side, and the side away from the outdoor exhaust port 201 is the outdoor side. When valve plate 2 closes the connecting channel 11, the first sealing rib 17 can be located on the indoor side of the first valve plate 22, and the second sealing rib 18 can be located on the outdoor side of the second valve plate 23, or the first sealing rib 17 can be located on the outdoor side of the first valve plate 22, and the second sealing rib 18 can be located on the indoor side of the second valve plate 23.

[0092] When the valve plate 2 closes the communication channel 11, the first sealing rib 17 can limit the first valve plate 22, and the second sealing rib 18 can limit the second valve plate 23, so that the valve plate 2 is kept in the position of closing the communication channel 11, ensuring the reliability of the valve plate 2 when closing the communication channel 11.

[0093] For example, in Figure 18 and Figure 24 In the example shown, the inner circumferential wall of the connecting channel 11 is provided with a first sealing rib 17 and a second sealing rib 18. The first sealing rib 17 and the second sealing rib 18 are located on opposite sides of the axis of the rotating shaft 21 and extend along the circumferential direction of the connecting channel 11. When the valve plate 2 opens the connecting channel 11, the first valve plate 22 is located on the side of the second valve plate 23 away from the outdoor exhaust port 201. When the valve plate 2 switches from the open state to the closed state, the first valve plate 22 rotates towards the outdoor exhaust port 201 and towards the first sealing rib 17, and the second valve plate 23 rotates towards the side away from the outdoor exhaust port 201 and towards the second sealing rib 18. When the valve plate 2 rotates to the position of closing the connecting channel 11, the first valve plate 22 is located on the side of the first sealing rib 17 away from the outdoor exhaust port 201 and abuts against the first sealing rib 17, and the second valve plate 23 is located on the side of the second sealing rib 18 facing the outdoor exhaust port 201 and abuts against the second sealing rib 18. Thus, the first sealing rib 17 and the second sealing rib 18 can respectively limit the first valve plate 22 and the second valve plate 23, so that the valve plate 2 can stay in the position of closing the communication channel 11 after rotation.

[0094] In some embodiments of this utility model, such as Figure 18 As shown, when the valve plate 2 closes the connecting channel 11, the first sealing rib 17 is located on the side of the valve plate 2 facing the outdoor exhaust port 201 in the thickness direction. The first sealing rib 17 and the second sealing rib 18 are staggered along the length direction of the connecting channel 11, with the first sealing rib 17 being closer to the outdoor exhaust port 201 than the second sealing rib 18. This allows the valve plate 2 to rotate to a position perpendicular to the axis of the connecting channel 11 when closing it, thus better sealing the connecting channel 11, reducing the possibility of cold air from the outside entering the air conditioner 100, and reducing the problem of condensation in the air conditioner 100.

[0095] In some embodiments of this utility model, such as Figures 18-20 As shown, for reference Figures 32-34 The valve plate 2 is located on the same plane at least for the portion that abuts against the first sealing rib 17 or the second sealing rib 18. This improves the limiting effect of the first sealing rib 17 on the first valve plate 22 and the limiting effect of the second sealing rib 18 on the second valve plate 23. At the same time, it improves the reliability of the seal between the first valve plate 22 and the first sealing rib 17, and between the second valve plate 23 and the second sealing rib 18, reducing the possibility of outdoor cold air entering the air conditioner 100 and reducing the problem of condensation in the air conditioner 100.

[0096] exist Figures 32-34 In the example shown, the valve plate 2 includes a rotating shaft 21 and a first valve plate 22 and a second valve plate 23 located on both sides of the rotating shaft 21. The first valve plate 22 and the second valve plate 23 are provided with reinforcing protrusions 24 to enhance the structural strength of the first valve plate 22 and the second valve plate 23. The portions of the first valve plate 22 and the second valve plate 23 excluding the reinforcing protrusions 24 are located on the same plane.

[0097] In some embodiments of this utility model, such as Figures 18-20 As shown, when the valve plate 2 closes the connecting channel 11, the portion of the valve plate 2 that abuts against the first sealing rib 17 or the second sealing rib 18 is perpendicular to the axis of the connecting channel 11. Therefore, at the position where the valve plate 2 closes the connecting channel 11, the first valve plate 22 and the first sealing rib 17 are in surface contact, and the second valve plate 23 and the second sealing rib 18 are also in surface contact. This improves the limiting effect of the first sealing rib 17 on the first valve plate 22 and the limiting effect of the second sealing rib 18 on the second valve plate 23. Simultaneously, it better improves the sealing performance between the first valve plate 22 and the first sealing rib 17, as well as between the second valve plate 23 and the second sealing rib 18, reducing the possibility of cold air from the outside entering the air conditioner 100 and reducing the problem of condensation in the air conditioner 100.

[0098] In some embodiments of this utility model, such as Figures 24-28 As shown, both ends of the first sealing rib 17 extend to the rotating shaft 21 along its length, and both ends of the second sealing rib 18 extend to the rotating shaft 21 along its length. This maximizes the length of the first sealing rib 17 and the second sealing rib 18. When the valve plate 2 closes the connecting channel 11, the contact length between the first valve plate 22 and the first sealing rib 17, as well as the contact length between the second valve plate 23 and the second sealing rib 18, is increased along the circumferential direction of the connecting channel 11. This better achieves the sealing of the connecting channel 11 by the valve plate 2, reducing the possibility of cold air from the outside entering the air conditioner 100 and reducing the problem of condensation in the air conditioner 100.

[0099] In some embodiments of this utility model, such as Figure 18 , Figure 24 , Figure 25 and Figure 27 As shown, for reference Figures 35-38 The exhaust pipe connector 10 also includes a sealing ring 3, which is fitted onto the edge of the valve plate 2. This increases the sealing reliability between the outer peripheral wall of the valve plate 2 and the inner peripheral wall of the connecting channel 11 when the valve plate 2 closes the connecting channel 11, or increases the sealing reliability between the valve plate 2 and the first sealing rib 17 and between the valve plate 2 and the second sealing rib 18. This reduces the possibility of cold air from the outside entering the air conditioner 100 and reduces the problem of condensation in the air conditioner 100.

[0100] Furthermore, such as Figure 19 , Figure 20 and Figure 38 As shown, the sealing ring 3 includes a first sealing part 31, a second sealing part 32, and a connecting part 33. The first sealing part 31 and the second sealing part 32 are located on both sides of the valve plate 2 in the thickness direction and extend annularly along the outer periphery of the valve plate 2. The connecting part 33 is located on the outer periphery of the valve plate 2 and is used to connect the first sealing part 31 and the second sealing part 32. It can be understood that, in the cross-section through the axis of the sealing ring 3, one side of the sealing ring 3 can be U-shaped, which can wrap around both the inner and outer sides of the circumference of the valve plate 2. This can improve the reliability of the sealing ring 3 being fixed on the valve plate 2. In addition, when the valve plate 2 closes the connecting channel 11, the first sealing part 31 of the portion of the first valve plate 22 and the sealing ring 3 opposite to the first valve plate 22 abuts against the first sealing rib 17. The first sealing part 31 of the sealing ring 3 is located between the first valve plate 22 and the first sealing rib 17, thus achieving a seal between the first valve plate 22 and the first sealing rib 17. The second sealing part 32 of the portion of the second valve plate 23 and the sealing ring 3 opposite to the second valve plate 23 abuts against the second sealing rib 18. The second sealing part 32 is located between the second valve plate 23 and the second sealing rib 18, thus achieving a seal between the second valve plate 23 and the second sealing rib 18. This reduces the possibility of outdoor cold air entering the air conditioner 100 and reduces the problem of condensation in the air conditioner 100.

[0101] During the assembly of the exhaust pipe connector 10, after the sealing ring 3 is fitted onto the valve plate 2, the valve plate 2 with the sealing ring 3 fitted onto it is installed on the connector body 1.

[0102] In a specific example of this utility model, the two ends of the first sealing rib 17 extend to the rotating shaft 21, and the two ends of the second sealing rib 18 extend to the rotating shaft 21. The first sealing part 31 and the second sealing part 32 form an annular shape. When the valve plate 2 closes the connecting channel 11, the valve plate 2, the sealing ring 3, the first sealing rib 17 and the second sealing rib 18 can achieve a complete seal, preventing cold air from leaking into the interior of the air conditioner 100 through the assembly gap between the valve plate 2 and the exhaust pipe joint 10, thus forming condensate.

[0103] In some embodiments of this utility model, such as Figures 35-37 As shown, the first sealing part 31 and the second sealing part 32 protrude in the direction away from the rotating shaft 21 at the position where they mate with the rotating shaft 21, and the first connecting part 33 has a clearance hole 34 at the position of the rotating shaft 21 for the rotating shaft 21 to pass through. This can maximize the area of ​​the sealing ring 3, improve the reliability of the seal between the valve plate 2 and the connector body 1, reduce the possibility of outdoor cold air entering the air conditioner 100, and reduce the problem of condensation in the air conditioner 100.

[0104] In some embodiments of this utility model, such as Figure 26 , Figure 28 , Figures 30-34 As shown, the exhaust pipe connector 10 also includes a drive motor 4, which is located outside the connector body 1 and connected to the valve plate 2, for driving the valve plate 2 to rotate. The drive motor 4 can be connected to the control module of the air conditioner 100. The control module can control the drive motor 4 to drive the valve plate 2 to move according to the operating status of the air conditioner 100, thereby opening or closing the connecting channel 11. This can automate the rotation of the valve plate 2 and improve the user experience.

[0105] exist Figure 26 , Figure 28 , Figures 30-34 In the example shown, the drive motor 4 is located outside the connector body 1, and the motor shaft 41 of the drive motor 4 extends into the communicating channel 11. One end of the rotating shaft 21 of the valve plate 2 is connected to the motor shaft 41, and the other end is rotatably located in the rotating hole of the connector body 1. The drive motor 4 and the connector body 1 can be connected by fasteners.

[0106] Optionally, such as Figures 25-28 As shown, two bushings 19 are provided on the inner peripheral wall of the connecting channel 11, and the two bushings 19 respectively define two rotating holes. The two ends of the rotating shaft 21 are rotatably disposed in the two bushings 19. Further, the two ends of the first sealing rib 17 are respectively connected to the two bushings 19, and the two ends of the second sealing rib 18 are respectively connected to the two bushings 19.

[0107] In some embodiments of this utility model, such as Figure 18 , Figure 25 , Figure 27 , Figure 30 and Figure 31 As shown, the connector body 1 along the length of the connecting channel 11 includes a first section 12 and a second section 14. The first section 12 is positioned relative to the second section 14 and close to the outdoor exhaust port 201. The connecting channel 11 includes a first channel 13 located within the first section 12 and a second channel 15 located within the second section 14. The outer contour of the cross-section of the second section 14 is circular, the cross-section of the second channel 15 is circular, and the outer contour of the cross-section of the first section 12 is quadrilateral. In the direction from the second section 14 to the first section 12, the cross-sectional area of ​​the first channel 13 gradually decreases, while the cross-sectional area of ​​the second channel 15 remains unchanged. The first sealing rib 17 and the second sealing rib 18 are provided on the inner peripheral wall of the second channel 15. The rotating shaft 21 of the valve plate 2 is rotatably connected to the second section 14.

[0108] In some embodiments of this utility model, such as Figure 18 , Figure 25 , Figure 27 , Figure 30 and Figure 31 As shown, the connector body 1 also includes a fixing plate 16, which is connected to the first section 12. The fixing plate 16 is used to connect to the housing 20 of the air conditioner 100, thereby fixing the exhaust pipe connector 10 to the housing 20 of the air conditioner 100.

[0109] Optionally, the mounting plate 16 can be snapped into the housing 20 of the air conditioner 100 and / or connected by fasteners.

[0110] For example, in Figure 25 and Figure 27 In the example shown, one end of the fixed plate 16 is snapped into the housing 20 of the air conditioner 100, and the other end is connected to the housing 20 of the air conditioner 100 by fasteners.

[0111] The following is for reference. Figures 1-14 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0112] like Figures 1-14 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 20 and the above-mentioned exhaust pipe connector 10.

[0113] Specifically, the housing 20 has an indoor heat exchange duct 203 and an outdoor heat exchange duct 204. The housing 20 also has an indoor air inlet and an indoor air outlet connected to the indoor heat exchange duct 203, and an outdoor air inlet and an outdoor air outlet 201 connected to the outdoor heat exchange duct 204. The indoor air inlet, indoor air outlet, and outdoor air inlet are connected to the indoor environment, and the outdoor air outlet 201 is connected to the outdoor environment. The connector body 1 is connected to the housing 20, and one end of the connecting channel 11 is connected to the outdoor air outlet 201.

[0114] It is understood that the air conditioner 100 is an integrated air conditioner. The air conditioner 100 also includes an indoor fan, an indoor heat exchanger, an outdoor fan, and an outdoor heat exchanger. The indoor fan and indoor heat exchanger are located in the indoor heat exchange duct 203, and the outdoor fan and outdoor heat exchanger are located in the outdoor heat exchange duct 204. The indoor fan is used to drive the airflow from the indoor air inlet to the indoor air outlet. The indoor heat exchanger is used to exchange heat with the airflow entering the indoor heat exchange duct 203. The outdoor fan is used to drive the airflow from the outdoor air inlet to the outdoor air outlet 201. The outdoor heat exchanger is used to exchange heat with the airflow entering the outdoor heat exchange duct 204.

[0115] One end of the connecting channel 11 is connected to the outdoor exhaust vent 201, and the other end is adapted to connect to the outdoor environment. The valve plate 2 is rotatably disposed in the connecting channel 11 and is used to open or close the connecting channel 11. The valve plate 2 can be rotated as needed, thereby enabling the outdoor exhaust vent 201 to connect to or disconnect from the outdoor environment through the rotation of the valve plate 2.

[0116] For example, the valve plate 2 on the exhaust pipe connector 10 opens or closes according to the operating status of the air conditioner 100. When the air conditioner 100 is on, the valve plate 2 opens the connecting channel 11, connecting the indoor and outdoor sides of the exhaust pipe connector 10, facilitating the airflow after heat exchange with the outdoor heat exchanger to be discharged outdoors through the exhaust pipe connector 10. When the air conditioner 100 is off, the valve plate 2 closes the connecting channel 11, closing the exhaust pipe connector 10 and isolating the indoor and outdoor air. In low-temperature environments, this prevents cold outdoor air from entering the air conditioner 100 and forming condensation, avoiding the quality risk of water dripping from the air conditioner panel 40, preventing user complaints, and improving product reliability and user experience.

[0117] In addition, when the air conditioner 100 is not turned on, that is, when the user is not using the air conditioner 100, the valve plate 2 on the exhaust pipe connector 10 is in a closed state, isolating the outdoor side and the indoor side of the exhaust pipe connector 10. This also prevents foreign objects such as fallen leaves, dust, rats, cockroaches, mosquitoes and other animals from the outdoor side from entering the air conditioner 100 through the exhaust pipe connector 10, thus protecting the air conditioner 100 and the indoor environment.

[0118] According to the embodiment of the present invention, the air conditioner 100 has an exhaust pipe connector 10 installed at the outdoor exhaust port 201. A rotatable valve plate 2 is installed inside the connector body 1. The valve plate 2 is used to open or close the connecting channel 11 of the connector body 1, thereby allowing the indoor and outdoor sides of the exhaust pipe connector 10 to be connected or isolated as needed. Specifically, when the air conditioner 100 is turned on, the valve plate 2 can open the connecting channel 11, connecting the indoor and outdoor sides of the exhaust pipe connector 10, allowing airflow inside the air conditioner 100 to be discharged through the outdoor exhaust port 201. When the air conditioner 100 is turned off, the valve plate 2 can close the connecting channel 11, isolating the indoor and outdoor sides of the exhaust pipe connector 10. In low-temperature environments, this prevents cold air from the outdoor side from entering the air conditioner 100 and forming condensate, avoiding the quality risk of water dripping from the air conditioner panel 40, preventing user complaints, and improving product reliability and user experience. In addition, it can prevent debris, insects and other pests from entering the air conditioner 100, thus protecting the air conditioner 100 and the indoor environment.

[0119] In some embodiments of this utility model, the air conditioner 100 further includes an exhaust pipe 30, one end of which is connected to the end of the connecting channel 11 away from the outdoor exhaust port 201, and the other end is connected to the outdoor environment. The exhaust pipe 30 can be a flexible hose to facilitate the exhaust airflow from the air conditioner 100 to the outside, thus avoiding affecting the indoor cooling and heating effects.

[0120] In some embodiments of this utility model, such as Figures 10-14 As shown, for reference Figures 1-3 The air conditioner 100 is installed on the ceiling 200. For example, if the air conditioner 100 is a kitchen air conditioner, the casing 20 of the air conditioner 100 is installed on the upper part of the ceiling 200, hidden inside the ceiling 200. The panel 40 of the air conditioner 100 is installed on the lower part of the casing 20, exposed at the bottom of the ceiling 200, so that the user can see the panel 40 when looking up. An indoor air inlet 2001 is also installed on the ceiling 200. The illustration shows two indoor air inlets 2001 installed, spaced apart from the panel 40 of the air conditioner 100. The indoor and outdoor air inlets can be connected to the indoor air inlets 2001 via ducts. An exhaust pipe connector 10 is installed on the casing 20, and an exhaust pipe 30 is installed on the outside of the exhaust pipe connector 10, leading to the outside. The panel 40 of the air conditioner 100 has an indoor air outlet 401, which is connected to an indoor air outlet.

[0121] When the air conditioner 100 is cooling, indoor air enters the ceiling 200 through the indoor air inlet 2001, and then enters the indoor heat exchange duct 203 and outdoor heat exchange duct 204 of the air conditioner 100 through the indoor air inlet and outdoor air inlet, respectively. The air entering the indoor heat exchange duct 203 exchanges heat with the indoor heat exchanger and is then blown out through the indoor air outlet and indoor side air outlet 401. The air entering the outdoor heat exchange duct 204 exchanges heat with the outdoor heat exchanger and becomes hot air, which then passes through the exhaust pipe connector 10 and the exhaust pipe 30 before being discharged to the outside. This effectively cools indoor spaces, such as kitchen spaces, by blowing out cool air and expelling hot air outdoors. During the process of expelling hot air, the valve plate 2 is in the open state.

[0122] In some embodiments of this utility model, such as Figures 10-14 As shown, the upper part of the housing 20 has a clearance groove 202. The indoor heat exchange air duct 203 and the outdoor heat exchange air duct 204 are located on both sides of the clearance groove 202. The ceiling 200 includes a keel 2002 arranged opposite to the air conditioner 100. The keel 2002 passes through the clearance groove 202, which allows the air conditioner 100 to be installed from bottom to top, which facilitates the installation of the air conditioner 100 without damaging the structure of the ceiling 200 and ensures the strength of the ceiling 200 structure.

[0123] like Figures 4-6 As shown, valve plate 2 is in the open state and rotates 90 degrees under the control of drive motor 4. At this time, the airflow area of ​​exhaust pipe connector 10 is at its maximum, and air conditioner 100 is in the on state. The indoor and outdoor air of exhaust pipe connector 10 are connected. With the rotation of the outdoor fan, the hot air in the outdoor heat exchange duct 204 is discharged from the outdoor exhaust port 201, passes through exhaust pipe connector 10, and then through exhaust pipe 30 before being discharged outdoors.

[0124] refer to Figures 21-24 With valve plate 2 in the open state, the cross-sectional area of ​​the exhaust pipe connector 10 is maximized, thereby maximizing the exhaust volume of the air conditioner 100. Drive motor 4 is installed outside the exhaust pipe connector 10. The drive shaft of drive motor 4 is inserted from the outside to the inside of the exhaust pipe connector 10, and then inserted into the rotating shaft 21 of valve plate 2 to drive valve plate 2 to rotate. The rotation range of valve plate 2 is 0 degrees to 90 degrees. At 0 degrees, valve plate 2 is in the closed state; at 90 degrees, valve plate 2 is in the open state. The sealing ring 3 is an annular structure with a frame-shaped cross-section, and it surrounds the outer circumference of valve plate 2.

[0125] When the user no longer needs to use the air conditioner 100, i.e., turns it off, the drive motor 4 will simultaneously drive the valve plate 2 to rotate to the 0-degree position, placing the valve plate 2 in a closed state. Figures 7-9 As shown. Valve plate 2 isolates the indoor and outdoor air of exhaust pipe connector 10. This prevents cold air from the outdoor side from flowing back into the air conditioner 100 through exhaust pipe 30 and forming condensation. It also prevents foreign objects from the outdoor side, such as fallen leaves, dust, rats, cockroaches, mosquitoes, etc., from entering the air conditioner 100.

[0126] In particular, the valve plate 2 is closed to prevent cold air backflow, effectively preventing cold air from entering the air conditioner 100 and forming condensation. When the air conditioner 100 is installed in a cold northern region, it is generally not needed in winter and will be in the off state. At this time, the outdoor temperature is cold, while the indoor temperature is generally warm due to heating, resulting in a significant temperature difference between the two. The cold air from the outdoor side will pass through the exhaust duct 30 and then through the exhaust duct connector 10. If the valve plate 2 is not closed, the cold air will backflow into the air conditioner 100. Since the air conditioner 100 is located indoors, when it encounters the low-temperature cold air, condensation will form inside the air conditioner 100. Over time, the condensation will slowly accumulate, overflow from the chassis, and drip from the panel 40. Therefore, the valve plate 2 driven by the drive motor 4 of this utility model can be rotated by the drive motor 4 when the air conditioner 100 is turned off and not in use, so that the valve plate 2 is in the 0-degree position and the valve plate 2 is in the closed state, effectively preventing the quality risk of the air conditioner 100 dripping water caused by cold air backflow.

[0127] Other configurations and operations of the air conditioner 100 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
