[0040] The utility model provides a fresh air duct assembly 100 for an air conditioner, wherein the air conditioner comprises an indoor unit 200 and an outdoor unit, wherein a refrigerant pipe 210 and a power line 220 are connected between the indoor unit 200 and the outdoor unit, and the indoor unit 200 also has a drain pipe for discharging condensed water.

[0041] In the embodiment of the present utility model, Figures 1 to 11 As shown, the new air duct assembly 100 includes:

[0042] A first sleeve 110 and a fresh air duct 120, wherein the first sleeve 110 is sleeved on the refrigerant pipe 210 and the fresh air duct 120, and the first sleeve 110 has a first port and a second port 111 opposite to each other, wherein the first port is connected to the indoor unit 200, and the inlet of the fresh air duct 120 is exposed at the second port 111; and

[0043] The adapter 130 is used to be installed in a mounting hole 310 opened in a wall 300 indoors. The second port 111 is installed in the adapter 130 so that the fresh air duct 120 can be connected to the outdoors through the mounting hole 310 .

[0044] Specifically, the indoor unit 200 is installed indoors, the outdoor unit is installed outdoors, and a mounting hole 310 is pre-opened in the wall 300 of the house. The refrigerant pipe 210 and the power line 220 pass through the mounting hole 310 to connect between the indoor unit 200 and the outdoor unit. The drain pipe passes through the mounting hole 310 and extends to the outdoors to discharge the condensed water in the air conditioner. In the prior art, the air conditioner draws fresh air into the room through the fresh air module, and uses the gaps of the doors and windows of the room to discharge the old air in the room. In order to facilitate installation and not to damage the wall 300, the fresh air duct 120 can only be penetrated through the mounting hole 310 together with the refrigerant pipe 210, so the inner diameter of the mounting hole 310 determines the size of the fresh air duct 120, and then determines the air flow area of ​​the fresh air duct 120. In order to facilitate the installation of the refrigerant pipe 210 and the fresh air pipe 120, the first sleeve 110 is sleeved on the refrigerant pipe 210 and the fresh air pipe 120, so that the refrigerant pipe 210, the fresh air pipe 120 and the first sleeve 110 form a bundled pipe. The diameter of the installation hole 310 determines the outer diameter of the first sleeve 110, resulting in a small cross-sectional area of ​​the fresh air pipe 120 (currently, the fresh air pipe 120 on the market mostly uses a hose with a diameter of 30 mm), and the utilization rate of the installation hole 310 is low, and there are often low fresh air volume and insufficient ventilation volume, which affects the ventilation efficiency of the fresh air module of the air conditioner.

[0045] In order to facilitate the installation of the refrigerant pipe 210 and the fresh air pipe 120, the first sleeve 110 is sleeved on the refrigerant pipe 210 and the fresh air pipe 120, so that the refrigerant pipe 210, the fresh air pipe 120 and the first sleeve 110 form a bundled pipe. The first port of the first sleeve 110 is connected to the indoor unit 200, so as to fix the first sleeve 110, and the inlet of the fresh air pipe 120 is exposed at the second port 111 of the first sleeve 110, and the second port 111 is installed on the adapter 130, and the adapter 130 is installed in the installation hole 310 indoors, so that the second port 111 is connected to the installation hole 310 and then to the outside, and the inlet of the fresh air pipe 120 is also connected to the installation hole 310 and then to the outside, so that the fresh air pipe 120 can be connected to the outside without being inserted into the installation hole 310, thereby reducing the influence of the diameter of the installation hole 310 on the diameter of the fresh air pipe 120. The refrigerant pipe 210 passes through the first sleeve 110 and the mounting hole 310 in sequence and extends to the outdoors to connect to the outdoor unit, and the gap between the refrigerant pipe 210 and the mounting hole 310 can be used to intake air, so that the outdoor air enters the adapter 130 through the gap between the refrigerant pipe 210 and the mounting hole 310, and then enters the fresh air pipe 120. Compared with the solution of extending the fresh air pipe 120 through the mounting hole 310 to the outdoors, this solution can make full use of the gap between the fresh air pipe 120 and the refrigerant pipe 210, thereby improving the utilization rate of the mounting hole 310 and increasing the effective wind passing area of ​​the mounting hole 310. And the size of the cross-sectional area of ​​the fresh air pipe 120 can be correspondingly increased, thereby improving the ventilation efficiency of the fresh air module of the air conditioner. The ventilation efficiency of the fresh air module of the air conditioner can be increased without destroying the wall 300 for the second time, and the installation of the air conditioner is convenient.

[0046] The adapter 130 is fixed at the mounting hole 310 of the wall 300, so as to facilitate the installation of the adapter 130. In the actual installation process, the adapter 130 can be fixed first, and then the refrigerant pipe 210 passes through the adapter 130, and the fresh air pipe 120 is fixed to the adapter 130, so as to facilitate the installation of the air conditioner. The adapter 130 can be bonded or clamped to the wall 300 or the periphery of the mounting hole 310.

[0047] The technical solution of the utility model is to provide a first sleeve 110, which is sleeved on the refrigerant pipe 210 and the fresh air pipe 120, so as to facilitate the installation of the refrigerant pipe 210 and the fresh air pipe 120. The first sleeve 110 has a first port and a second port 111 relative to each other, the first port is connected to the indoor unit 200, the inlet of the fresh air pipe 120 is exposed at the second port 111, and the adapter 130 is installed in the installation hole 310 indoors, so that the second port 111 is connected to the installation hole 310 and then to the outside, and the inlet of the fresh air pipe 120 is also connected to the installation hole 310 and then to the outside, and the fresh air pipe 120 can be connected to the outside without being inserted into the installation hole 310, thereby reducing the influence of the diameter of the installation hole 310 on the diameter of the fresh air pipe 120. And the gap between the refrigerant pipe 210 and the installation hole 310 can be used for air intake, thereby improving the utilization rate of the installation hole 310 and the effective air flow area of ​​the installation hole 310. And the cross-sectional area of ​​the fresh air duct 120 can be correspondingly increased, thereby improving the ventilation efficiency of the fresh air module of the air conditioner.

[0048] Refer again Figures 1 to 11 In one embodiment, the adapter 130 includes a first installation pipe section 131 and a second installation pipe section 132 which are connected to each other, the second installation pipe section 132 is plugged into the installation hole 310, the first installation pipe section 131 is located indoors, and the second port 111 is plugged into the first installation pipe section 131. Specifically, the first installation pipe section 131 is located indoors, and the second port 111 is plugged into the first installation pipe section 131, so that the fresh air duct 120 is fixed in the first installation pipe section 131, and to ensure the installation stability, the first installation pipe section 131 clamps the periphery of the second port 111. And the inner periphery of the end of the first installation pipe section 131 away from the second installation pipe can be roughened, so as to increase the roughness of the first sleeve 110 and the first installation pipe section 131, thereby reducing the possibility of the first installation pipe section 131 and the first sleeve 110 being separated. The second installation pipe section 132 is inserted into the installation hole 310, so as to fix the adapter 130 in the installation hole 310, and there is no need to set up another fixing structure on the wall 300, thereby reducing secondary damage to the wall 300. During installation, it is only necessary to insert the second installation pipe section 132 into the installation hole 310, which is convenient for installing the adapter 130. In order to ensure the installation stability of the adapter 130 and to facilitate the insertion of the second installation pipe section 132 into the installation hole 310, preferably, the second installation pipe section 132 and the installation hole 310 are interference fit or transition fit, and the insertion depth of the second installation pipe section 132 is less than or equal to the thickness of the wall 300. Preferably, the insertion depth of the second installation pipe section 132 is less than or equal to 10 cm and greater than or equal to 5 cm. Specifically, the insertion depth of the second installation pipe section 132 is 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, etc.

[0049] To further facilitate the installation of the first sleeve 110 and the adapter 130, the adapter 130 includes a main body 133 and a cover 134. The cover 134 covers the main body 133 and forms a first installation pipe section 131 together with the main body 133. The second installation pipe section 132 is arranged on the main body 133. Specifically, the second installation pipe section 132 is arranged on the main body 133, that is, the main body 133 is used to be fixed to the wall 300. The cover 134 covers the main body 133 and forms a first installation pipe section 131 together with the main body 133, that is, the first installation pipe section 131 includes two semi-annular pipe sections spliced ​​to each other. When installing, the second port 111 is first placed in the semi-annular pipe section of the main body 133, and then the cover 134 is covered, so that the second port 111 is pressed tightly in the first installation pipe section 131.

[0050] In order to further facilitate the installation of the main body 133 and the cover body 134, in one embodiment, the main body 133 and the cover body 134 are snap-fitted, thereby facilitating installation. For example, in one embodiment, one of the main body 133 and the cover body 134 is provided with an insertion hole 136, and the other is provided with an insertion protrusion 135, and the insertion protrusion 135 is inserted into the insertion hole 136, thereby facilitating the installation of the two, ensuring the installation stability, and reducing the possibility of the main body 133 and the cover body 134 being misaligned with each other.

[0051] Furthermore, the main body 133 and the cover 134 are fastened together by fasteners, thereby further ensuring that the cover 134 presses the main body 133 , which on the one hand ensures the installation stability of the first sleeve 110 , and on the other hand reduces the possibility of airflow leakage from the first installation pipe section 131 .

[0052] Reference Figures 1 to 6 When the indoor unit 200 is configured as a wall-mounted air conditioner indoor unit 200, and the wall 300 where the indoor unit 200 is installed is the same as the wall 300 where the installation hole 310 is located, the axial direction of the first installation pipe section 131 is set at an angle with the axial direction of the second installation pipe section 132. Preferably, the axial direction of the first installation pipe section 131 is set perpendicular to the axial direction of the second installation pipe section 132, so that when the second installation pipe section 132 is inserted into the installation hole 310, the axial direction of the first installation pipe section 131 is set roughly parallel to the wall 300, so that the first installation pipe section 131 can be set close to the wall 300, which increases the installation stability of the first installation pipe section 131 on the one hand, and facilitates the insertion of the first sleeve 110 into the first installation pipe section 131 along the wall 300 on the other hand, so that the first sleeve 110 is set as close to the wall 300 as possible, thereby facilitating the installation of the first sleeve 110 and arranging the first sleeve 110.

[0053] Reference Figures 7 to 11When the indoor unit 200 is configured as a wall-mounted air conditioner indoor unit 200, and the wall 300 on which the indoor unit 200 is installed is different from the wall 300 on which the installation hole 310 is located; or when the indoor unit 200 is configured as a floor-standing air conditioner indoor unit 200, the axial direction of the first installation pipe segment 131 is arranged in parallel with the axial direction of the second installation pipe segment 132. Specifically, the axial direction of the first installation pipe segment 131 is arranged in parallel with the axial direction of the second installation pipe segment 132, so that the first installation pipe segment 131 is arranged substantially perpendicular to the wall 300 on which the installation hole 310 is located, thereby facilitating the first sleeve 110 to be directly plugged into the first installation pipe segment 131, thereby facilitating the installation of the first sleeve 110.

[0054] In one embodiment, referring to Figures 1 to 11 , the inner diameter of the second installation pipe section 132 is smaller than the inner diameter of the first installation pipe section 131. Specifically, because the fresh air duct 120 is only plugged into the first installation pipe section 131, the second installation pipe section 132 does not need to be inserted. When the air enters, the airflow passes through the gap between the second installation pipe section 132 and the refrigerant pipe 210 and enters the fresh air duct 120. Therefore, the inner diameter of the second installation pipe section 132 is appropriately reduced, and the effective air intake area of ​​the second installation pipe section 132 can be set to be equivalent to the air intake area of ​​the fresh air duct 120, so that the air intake of the fresh air duct 120 is more uniform, and the inner diameter of the second installation pipe section 132 is reduced, and the outer diameter of the corresponding second installation pipe section 132 is also reduced, and the diameter of the corresponding required installation hole 310 is reduced.

[0055] Furthermore, the inner diameter of the second installation pipe section 132 is greater than or equal to the outer diameter of the second sleeve 140. Preferably, the effective air inlet area of ​​the second installation pipe section 132 is set to be equivalent to the air inlet area of ​​the fresh air duct 120, and the inner diameter of the second installation pipe section 132 is greater than the outer diameter of the second sleeve 140. In other embodiments, when the ventilation volume required by the fresh air module of the air conditioner is small, the inner diameter of the second installation pipe section 132 can also be equal to the outer diameter of the second sleeve 140. At this time, the airflow passes through the gap between the second installation pipe section 132 and the refrigerant pipe 210, and the diameter of the installation hole 310 can also be further reduced, thereby reducing its damage to the wall 300.

[0056] In another embodiment, the thickness of the second installation pipe section 132 is less than or equal to 3 mm. When the installation strength of the adapter 130 is met, the smaller the thickness of the second installation pipe section 132, the smaller the diameter of the installation hole 310 occupied by it, and the larger the effective air flow area of ​​the installation hole 310. The air intake of the fresh air duct 120 depends on the gap between the second installation pipe section 132 and the refrigerant pipe 210. The larger the gap between the two, the larger the air intake of the fresh air duct 120. Therefore, the thickness of the second installation pipe section 132 is less than or equal to 3 mm, thereby further increasing the effective air flow area of ​​the installation hole 310, and then increasing the air intake of the fresh air duct 120. Specifically, the thickness of the second installation pipe section 132 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0057] Refer again Figures 1 to 11 In one embodiment, the fresh air duct assembly 100 further includes a second sleeve 140. The refrigerant pipe 210, the drain pipe and the power line 220 all pass through the first sleeve 110 and the mounting hole 310 and extend to the outside. The second sleeve 140 extends from the inside and outside of the mounting hole 310 to the outside and is sleeved on the refrigerant pipe 210, the drain pipe and the power line 220. Specifically, the second sleeve 140 extends from the inside and outside of the mounting hole 310 to the outside, that is, part of the second sleeve 140 is located in the mounting hole 310, and the other part is located outdoors. The second sleeve 140 is sleeved on the refrigerant pipe 210, the drain pipe and the power line 220, so that the second sleeve 140, the refrigerant pipe 210, the drain pipe and the power line 220 together form a bundled pipe to facilitate the installation of the refrigerant pipe 210, the drain pipe and the power line 220. The refrigerant pipe 210 and the power cord 220 are both connected between the indoor unit 200 and the outdoor unit. The drain pipe is used to discharge condensed water in the air conditioner. Therefore, the refrigerant pipe 210, the drain pipe and the power cord 220 all pass through the first sleeve 110 and the installation hole 310 and extend to the outdoors. That is, the parts of the refrigerant pipe 210, the drain pipe and the power cord 220 located outdoors are wrapped by the second sleeve 140, and the parts located indoors are wrapped by the first sleeve 110, which not only facilitates the installation of the refrigerant pipe 210, the drain pipe and the power cord 220, but also avoids the mess of pipes or lines after installation.

[0058] Further, the first sleeve 110 is formed by wrapping around the refrigerant pipe 210, the drain pipe, the power line 220 and the fresh air pipe 120. Specifically, the wrapping tape is spirally wound around the refrigerant pipe 210, the drain pipe, the power line 220 and the fresh air pipe 120 along the axial direction of the refrigerant pipe 210, thereby forming the first sleeve 110, and the first sleeve 110 extends from the indoor unit 200 to the inlet of the fresh air pipe 120. The first sleeve 110 can be installed after the refrigerant pipe 210, the drain pipe and the power line 220 are penetrated with the mounting hole 310, or it can be installed before the mounting hole 310 is penetrated, thereby improving the flexibility of installation. The wrapping tape is low in cost, easy to install, and can also reduce the cost of the air conditioner. In other embodiments, the first sleeve 110 can also be a heat shrink tube.

[0059] The second sleeve 140 is formed by winding the refrigerant pipe 210, the drain pipe and the power line 220 via the wrapping tape. Specifically, the wrapping tape is spirally wound along the axial direction of the refrigerant pipe 210 and the refrigerant pipe 210, the drain pipe and the power line 220 to form the second sleeve 140, and the second sleeve 140 extends from the mounting hole 310 to the outdoor unit. If the drain pipe is not connected to the outdoor unit, it can be removed from the second sleeve 140 after passing through the mounting hole 310 for a distance, that is, the second sleeve 140 is wound outside the refrigerant pipe 210 and the drain pipe. The second sleeve 140 can be installed after the refrigerant pipe 210, the drain pipe and the power line 220 are penetrated with the mounting hole 310, or it can be installed before the mounting hole 310 is penetrated, thereby improving the flexibility of installation. The wrapping tape is low in cost, easy to install, and can also reduce the cost of the air conditioner. In other embodiments, the second sleeve 140 can also be a heat shrink tube.
