[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0039] Combination Figure 1 As shown, the embodiment of the present disclosure provides a fresh air air conditioner, including: a first tube body 100 and a second tube body 200. The first tube body 100 includes a first bent portion 110 and a first straight portion 120, and the first bent portion 110 and the first straight portion 120 are connected to jointly enclose an air flow cavity 130; the second tube body 200 includes a second bent portion 210 and a second straight portion 220, and the second bent portion 210 and the second straight portion 220 are connected to jointly enclose a refrigerant flow cavity 230; wherein the first straight portion 120 and the second straight portion 220 are spliced ​​so that the first tube body 100 and the second tube body 200 are spliced ​​to form a whole adapted to the shape of the wall hole.

[0040] With the fresh air air conditioner provided by the embodiment of the present disclosure, during the installation of the fresh air air conditioner, the first straight portion 120 of the first tube body 100 and the second straight portion 220 of the second tube body 200 can be spliced, so that the first tube body 100 and the second tube body 200 are spliced ​​to form a whole body that fits the shape of the wall hole. The first tube body 100 and the second tube body 200 can pass through the same wall hole, thereby reducing the number of wall holes, reducing the difficulty of construction, and improving installation efficiency.

[0041] Optionally, the cross section of the first tube body 100 is semicircular. In this way, during the installation of the fresh air air conditioner, a wall hole is drilled on the wall by a handheld drilling machine, and the shape of the wall hole is usually circular. Since the first tube body 100 and the second tube body 200 need to pass through the same wall hole together, the semicircular cross section of the first tube body 100 can make full use of the space of the wall hole, increase the flow area of ​​the airflow cavity 130 in the first tube body 100, and leave a margin for the second tube body 200 to pass through the wall hole.

[0042] Optionally, the cross section of the second tube body 200 is semicircular. In this way, the cross section of the second tube body 200 is semicircular, which is compatible with the semicircular cross section of the first tube body 100. After the first straight portion 120 and the second straight portion 220 are spliced, the cross section of the first tube body 100 and the cross section of the second tube body 200 are spliced ​​into a circle, thereby adapting to the circular wall hole and making full use of the space of the wall hole. After the first tube body 100 and the second tube body 200 are spliced, they can pass through the same wall hole, thereby reducing the number of wall holes, reducing the difficulty of construction, and improving installation efficiency.

[0043] It can be understood that the outer side wall of the first bent portion 110 of the first tube body 100 is a smooth side wall, and the friction force is relatively small during the process of passing through the wall hole, and the difficulty of passing through is relatively low. The outer side wall of the second bent portion 210 of the second tube body 200 is also a smooth side wall, and the friction force is relatively small during the process of passing through the wall hole, and the difficulty of passing through is relatively low.

[0044] It can be understood that the outer wall of the first straight portion 120 of the first tube body 100 is a smooth side wall, and the outer wall of the second straight portion 220 of the second tube body 200 is a smooth side wall. The second tube body 200 can be passed through the wall hole first, and then the first tube body 100 can be passed through the wall hole. Since the outer walls of the first straight portion 120 and the outer walls of the second straight portion 220 are both smooth side walls, the friction between the first tube body 100 and the second tube body 200 is relatively small, and the difficulty of penetration is low.

[0045] Specifically, the first bending portion 110 is a first arc-shaped plate; the first straight portion 120 is a first straight plate; the second bending portion 210 is a second arc-shaped plate; and the second straight portion 220 is a second straight plate.

[0046] Combination Figure 2 As shown, in one embodiment, the fresh air air conditioner further includes: a third tube body 300. The third tube body 300 has a first end 310 and a second end 320, the first end 310 is connected to one end of the first tube body 100, and the second end 320 is arranged to face away from the first tube body 100. The cross section of the third tube body 300 changes along its radial direction, and the flow area of ​​the first end 310 is the same as the flow area of ​​the second end 320. In this way, the first end 310 of the third tube body 300 is connected to one end of the first tube body 100, and is connected to the internal pipeline of the fresh air air conditioner indoor unit through the second end 320 of the third tube body 300. Since the cross section of the third tube body 300 changes along its radial direction, the cross-sectional shape of the first end 310 is different from the cross-sectional shape of the second end 320, and the effect of being connected to the pipelines of the first tube body 100 and the fresh air air conditioner indoor unit is better, and the loss of airflow is reduced. The flow area of ​​the first end 310 is the same as the flow area of ​​the second end 320, which can reduce the fluctuation of the air pressure value and make the air pressure more stable.

[0047] It can be understood that the pipe of the indoor unit of the fresh air air conditioner is a circular pipe, which is different from the cross-sectional shape of the first pipe body 100. If the first pipe body 100 is directly connected to the circular pipe in the fresh air air conditioner, in order to prevent the circular pipe from reducing the internal airflow after being connected to the first pipe body 100, the cross-sectional area of ​​the circular pipe can only be larger than the cross-sectional area of ​​the first pipe body 100. That is, the flow rate of the circular pipe is larger than that of the first pipe body 100, which makes the diameter of the circular pipe larger and the cost higher. Therefore, the cross-sectional area of ​​the third pipe body 300 changes along its radial direction so that the first end 310 of the third pipe body 300 is connected to one end of the first pipe body 100, and the other end is connected to the circular pipe of the indoor unit of the fresh air air conditioner, thereby reducing the diameter of the circular pipe and reducing the cost.

[0048] Optionally, when the axis of the third tube body 300 is horizontally arranged and the length of the cross section of the first end 310 in the horizontal direction is greater than the length of the cross section of the second end 320 in the horizontal direction, the length of the cross section of the first end 310 in the vertical direction is less than the length of the cross section of the second end 320 in the vertical direction, so that the flow area of ​​the first end 310 is the same as the flow area of ​​the second end 320. In this way, the flow area of ​​the first end 310 is the same as the flow area of ​​the second end 320, which can reduce the loss of air flow in the third tube body 300, reduce the fluctuation of the air pressure value, and make the air pressure more stable.

[0049] It can be understood that when the axis of the third tube body 300 is set horizontally and the length of the cross-section of the first end 310 in the horizontal direction is smaller than the length of the cross-section of the second end 320 in the horizontal direction, the length of the cross-section of the first end 310 in the vertical direction is larger than the length of the cross-section of the second end 320 in the vertical direction, so that the flow area of ​​the first end 310 is the same as the flow area of ​​the second end 320.

[0050] Optionally, the cross section of the first end 310 is the same as the cross section of the first tube body 100. In this way, when the first end 310 is connected to one end of the first tube body 100, since the cross section of the first end 310 is the same as the cross section of the first tube body 100, the airflow between the first tube body 100 and the third tube body 300 is more stable.

[0051] Optionally, a third partition plate 330 is provided in the third tube body 300, and the third partition plate 330 divides the third tube body 300 into a first connecting cavity 340 and a second connecting cavity 350. In this way, the first connecting cavity 340 and the second connecting cavity 350 can provide circulation channels for the inlet airflow and the exhaust airflow, respectively, to avoid mutual interference between the inlet airflow and the exhaust airflow.

[0052] In another embodiment, the fresh air air conditioner further includes: a third tube body 300. The third tube body 300 has a first end 310 and a second end 320, the first end 310 is connected to one end of the first tube body 100, the second end 320 is arranged to face away from the first tube body 100, the cross section of the third tube body 300 changes along its radial direction, and the flow area of ​​the first end 310 is greater than the flow area of ​​the second end 320. In this way, the first end 310 of the third tube body 300 is connected to one end of the first tube body 100, and is connected to the pipeline of the indoor unit of the fresh air air conditioner through the second end 320 of the third tube body 300. Since the cross section of the third tube body 300 changes along its radial direction, the cross-sectional shape of the first end 310 is different from the cross-sectional shape of the second end 320, and the effect of being connected to the pipelines of the first tube body 100 and the indoor unit of the fresh air air conditioner respectively is better, and the loss of airflow is reduced. The flow area of ​​the first end 310 is larger than the flow area of ​​the second end 320 . The flow area of ​​the second end 320 is relatively large, so that the airflow of the second end 320 flows more smoothly.

[0053] Combination Figure 3 As shown, optionally, the fresh air air conditioner further includes: an assembly tube body 400. One end of the assembly tube body 400 is connected to the second end 320 of the third tube body 300; wherein the cross section of the assembly tube body 400 is circular. In this way, the second end 320 of the third tube body 300 is connected to one end of the assembly tube body 400, and the assembly tube body 400 is connected to the internal pipeline of the fresh air air conditioner. Due to the shape restrictions of the first tube body 100 and the third tube body 300, bending is more difficult. The cross section of the assembly tube body 400 is circular, and it is easier to bend the assembly tube body 400, thereby reducing the difficulty of installing the fresh air air conditioner.

[0054] Optionally, the cross section of the second end 320 is the same as the cross section of the assembly tube body 400. In this way, when the second end 320 of the third tube body 300 is connected to one end of the assembly tube body 400, since the cross section of the second end 320 is the same as the cross section of the assembly tube body 400, the airflow between the assembly tube body 400 and the third tube body 300 is more stable.

[0055] Optionally, a fourth partition plate 410 is provided in the assembly tube body 400, and the fourth partition plate 410 divides the assembly tube body 400 into a third connecting chamber 420 and a fourth connecting chamber 430. In this way, the third connecting chamber 420 and the fourth connecting chamber 430 can provide circulation channels for the inlet airflow and the exhaust airflow, respectively, to avoid mutual interference between the inlet airflow and the exhaust airflow.

[0056] Specifically, when one end of the assembly tube body 400 is connected to the second end 320 of the third tube body 300 , the third connecting cavity 420 is connected to the first connecting cavity 340 , and the fourth connecting cavity 430 is connected to the second connecting cavity 350 .

[0057] Combination Figure 4 As shown, optionally, a reinforcement piece 500 is provided on the outer side wall of the third tube body 300. In this way, the structural strength of the third tube body 300 is improved by the reinforcement piece 500.

[0058] Optionally, the reinforcing member 500 includes: a spiral reinforcing rib 510 and / or a reinforcing groove 520. In this way, when the outer side wall of the third tube 300 is provided with a spiral reinforcing rib 510, the structural strength of the third tube 300 is improved by the spiral reinforcing rib 510. When the outer side wall of the third tube 300 is provided with a reinforcing groove 520, the structural strength of the third tube 300 is improved by the reinforcing groove 520. When the third tube 300 is provided with both the spiral reinforcing rib 510 and the reinforcing groove 520, the structural strength of the third tube 300 is further improved.

[0059] Combination Figure 5 and Figure 6 As shown, optionally, a first partition 140 is provided in the first tube body 100, and the first partition 140 divides the airflow cavity 130 of the first tube body 100 into an air inlet cavity 131 and an air outlet cavity 132. In this way, the fresh air air conditioner introduces fresh oxygen-rich air from the outdoor into the room through the air inlet cavity 131, and exhausts the indoor air to the outdoor through the air outlet cavity 132. The air inlet cavity 131 and the air outlet cavity 132 provide circulation channels for the air inlet and the air outlet respectively, so as to avoid mutual interference between the air inlet and the air outlet.

[0060] Specifically, when the first end 310 of the third tube body 300 is connected to one end of the first tube body 100 , the first connecting cavity 340 is connected to the air inlet cavity 131 , and the second connecting cavity 350 is connected to the air exhaust cavity 132 .

[0061] Optionally, the flow rate of the air inlet chamber 131 is greater than the flow rate of the air outlet chamber 132. In this way, the amount of air introduced into the room from the air inlet chamber 131 is greater than the amount of air discharged from the room from the air outlet chamber 132, so that the indoor air pressure is greater than the outdoor air pressure, preventing the untreated outdoor air from entering the room through the gaps such as door gaps and window gaps, thereby improving the quality of indoor air.

[0062] It is understandable that in the process of fresh air air conditioning introducing outdoor air into the room, filtering devices, humidification devices, etc. will be set up to process the air, making the air clean and moist, thereby improving the user experience.

[0063] Optionally, the flow rate of the exhaust chamber 132 is less than or equal to seven eighths of the flow rate of the air inlet chamber 131, and greater than or equal to one fifth of the flow rate of the air inlet chamber 131. In this way, when the flow rate of the exhaust chamber 132 is greater than seven eighths of the flow rate of the air inlet chamber 131, the pressure difference between indoor and outdoor is too small, and the risk of untreated outdoor air entering the indoor through gaps such as door gaps and window gaps is high. When the flow rate of the exhaust chamber 132 is less than one fifth of the flow rate of the air inlet chamber 131, the pressure difference between indoor and outdoor is too large, and the speed at which indoor air flows out of the outdoor through gaps such as door gaps and window gaps is fast, and the risk of generating wind noise is high. Therefore, the range in which the flow rate of the exhaust chamber 132 is less than or equal to seven eighths of the flow rate of the air inlet chamber 131 and greater than or equal to one fifth of the flow rate of the air inlet chamber 131 is more reasonable, which reduces the risk of untreated outdoor air entering the indoor through gaps such as door gaps and window gaps, and also reduces the risk of generating wind noise.

[0064] Specifically, the flow rate of the exhaust cavity 132 is equal to three sevenths of the flow rate of the inlet cavity 131. In this way, the risk of untreated outdoor air entering the room through gaps such as door gaps and window gaps is reduced, and the risk of wind noise is also reduced.

[0065] Specifically, the flow rate of the exhaust cavity 132 is equal to one quarter of the flow rate of the inlet cavity 131. In this way, the risk of untreated outdoor air entering the room through gaps such as door gaps and window gaps is reduced, and the risk of wind noise is also reduced.

[0066] Optionally, an air inlet 133 communicating with the air inlet cavity 131 and an air outlet 134 communicating with the air outlet cavity 132 are provided at one end of the first tube body 100; wherein, the distance of one of the air inlet 133 and the air outlet 134 away from the other end of the first tube body 100 is greater than the distance of the other away from the other end of the first tube body 100. In this way, there is a gap between the air inlet 133 and the air outlet 134, and the distance between the airflow discharged from the air outlet 134 and the air inlet 133 is relatively far, thereby reducing the risk of the discharged airflow flowing back into the air inlet cavity 131.

[0067] Optionally, the distance between the air outlet 134 and the other end of the first tube body 100 is greater than the distance between the air inlet 133 and the other end of the first tube body 100. In this way, there is a gap between the air inlet 133 and the air outlet 134, and the distance between the airflow discharged from the air outlet 134 and the air inlet 133 is relatively far, reducing the risk of the discharged airflow flowing back into the air inlet cavity 131.

[0068] Optionally, a second partition 240 is provided in the second tube body 200, and the second partition 240 divides the refrigerant flow cavity 230 of the second tube body 200 into a first flow cavity 231 and a second flow cavity 232. In this way, the first flow cavity 231 and the second flow cavity 232 provide channels for the flow of the refrigerant, respectively, to avoid mutual interference between the refrigerant in the first flow cavity 231 and the refrigerant in the second flow cavity 232.

[0069] Optionally, the flow rate of the first circulation cavity 231 is greater than the flow rate of the second circulation cavity 232. In this way, the first circulation cavity 231 provides a channel for the circulation of the gaseous refrigerant, and the second circulation cavity 232 provides a channel for the liquid circulation cavity. Since the flow rate required for the gaseous refrigerant is larger, the flow rate of the first circulation cavity 231 is greater than the flow rate of the second circulation cavity 232, so that the circulation of the refrigerant is smoother.
