While regulating the indoor temperature, they can also achieve indoor and outdoor air exchange, introduce outdoor fresh air and exhaust indoor dirty air, effectively improving indoor air quality. Compared with traditional air conditioners, fresh air air conditioners can not only provide a comfortable cooling and heating environment, but also have multiple functions such as air purification, dehumidification, and energy saving. Compared with ordinary air conditioners, fresh air air conditioners have more fresh air inlet and outlet pipes, which reduces the efficiency of installing air conditioners and increases the cost of air conditioners.

The fresh air duct includes: a main body, which defines an air inlet channel for communicating with the fresh air inlet, and an exhaust channel for communicating with the outdoor air outlet; the air inlet channel and the exhaust channel both extend along the length direction of the main body, and are separated by a partition located inside the main body; the fresh air duct also includes a pipe body joint; the pipe body joint includes an air inlet pipe joint and an exhaust pipe joint, one end of the air inlet pipe joint is connected to the air inlet channel, and the other end is used to communicate with the fresh air inlet of the air conditioning device. By arranging a partition inside the main body to separate, an air inlet channel and an exhaust channel are formed, and the number of pipes extending from indoors to outdoors is reduced, thereby reducing the cost of the air conditioning device and improving the installation efficiency of the air conditioning device.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Since the ports of the air inlet channel and the air exhaust channel are adjacent to each other, there is a greater risk that the airflow at the port of the air exhaust channel will flow back into the air inlet channel.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] In some embodiments, the air conditioner includes: a duct assembly as in the above embodiments.

[0019] The air duct assembly and air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] Since the air duct body is provided with a partition, and the partition extends upward along the axis of the air duct body to divide the air duct body into an air inlet chamber and an air exhaust chamber, and the partition is spirally arranged along the axis of the air duct body, when the air conditioner exhausts air to the outside through the exhaust chamber, the airflow forms a spiral airflow under the guidance of the exhaust chamber and is discharged to the outside, the spiral airflow has better diffusion, and the gas discharged outside is more dispersed, reducing the risk of the airflow in the exhaust chamber flowing back to the air inlet chamber.

[0040] 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.

[0041] Combination Figure 1-3 As shown, the embodiment of the present disclosure provides an air duct assembly including: an air duct body 100 and a partition 200. The partition 200 is arranged in the air duct body 100, and extends upward along the axial direction of the air duct body 100 to divide the air duct body 100 into an air inlet chamber 110 and an air outlet chamber 120; wherein the partition 200 is spirally arranged along the axial direction of the air duct body 100.

[0042] With the air duct assembly provided by the embodiment of the present disclosure, the air duct body 100 is provided with a partition 200, and the partition 200 extends upward along the axis of the air duct body 100 to divide the air duct body 100 into an air inlet chamber 110 and an air outlet chamber 120, and the partition 200 is spirally arranged along the axis of the air duct body 100. When the air conditioner exhausts air to the outside through the air outlet chamber 120, the airflow forms a spiral airflow under the guidance of the air outlet chamber 120 and is discharged to the outside. The spiral airflow has better diffusion, and the gas discharged to the outside is more dispersed, reducing the risk of the airflow in the air outlet chamber 120 flowing back to the air inlet chamber 110.

[0043] Optionally, the number of spiral turns of the partition 200 is greater than or equal to 0.5 turns, and less than or equal to 5 turns. In this way, when the number of spiral turns of the partition 200 is less than 0.5 turns, the diffusivity of the spiral airflow discharged from the exhaust chamber 120 is relatively poor. When the number of spiral turns of the partition 200 is greater than 5 turns, the air inlet resistance of the air inlet chamber 110 and the air exhaust resistance of the exhaust chamber 120 are too large. It can be seen that the range of the number of spiral turns of the partition 200 being greater than or equal to 0.5 turns and less than or equal to 5 turns is more reasonable, the diffusivity of the spiral airflow discharged from the exhaust chamber 120 is better, and the air inlet resistance of the air inlet chamber 110 and the air exhaust resistance of the exhaust chamber 120 are also relatively small.

[0044] Specifically, the number of spiral turns of the partition plate 200 is equal to 2. In this way, the diffusivity of the spiral airflow discharged from the exhaust cavity 120 is better, and the air inlet resistance of the air inlet cavity 110 and the air exhaust resistance of the exhaust cavity 120 are relatively small.

[0045] Optionally, an air inlet 111 communicating with the air inlet cavity 110 and an air outlet 121 communicating with the air outlet cavity 120 are provided at one end of the air duct body 100; wherein, the distance of one of the air inlet 111 and the air outlet 121 facing away from the other end of the air duct body 100 is greater than the distance of the other facing away from the other end of the air duct body 100. In this way, there is a gap between the air inlet 111 and the air outlet 121, the distance between the airflow discharged from the air outlet 121 and the air inlet 111 is relatively far, and the airflow forms a spiral airflow under the guidance of the air outlet cavity 120 and is discharged outdoors, further reducing the risk of the discharged airflow flowing back into the air inlet cavity 110.

[0046] Optionally, the distance between the exhaust port 121 and the other end of the duct body 100 is greater than the distance between the air inlet 111 and the other end of the duct body 100. In this way, there is a gap between the air inlet 111 and the exhaust port 121, the distance between the airflow discharged from the exhaust port 121 and the air inlet 111 is relatively far, and the airflow forms a spiral airflow under the guidance of the exhaust cavity 120 and is discharged outdoors, further reducing the risk of the exhausted airflow flowing back into the air inlet cavity 110.

[0047] It is understandable that the larger the distance between the air outlet 121 and the air inlet 111 , the lower the risk of the airflow flowing back into the air inlet cavity 110 .

[0048] Optionally, the air duct body 100 is made of polyvinyl chloride material. Thus, the air duct body 100 made of polyvinyl chloride material has good chemical corrosion resistance, moisture resistance and flame retardancy, and the production cost is relatively low.

[0049] Combination Figure 4 As shown, optionally, the air duct assembly further includes: a shielding member 300. The shielding member 300 is sleeved on one end of the air duct body 100, and is disposed between the air inlet 111 and the air outlet 121 to provide shielding between the air outlet 121 and the air inlet 111. In this way, by disposing the shielding member 300 between the air inlet 111 and the air outlet 121 to provide shielding between the air outlet 121 and the air inlet 111, the risk of the discharged airflow flowing back into the air inlet chamber 110 is reduced.

[0050] Optionally, the shielding member 300 includes: a first shielding plate 310 and a second shielding plate 320. The first shielding plate 310 is sleeved with one end of the air duct body 100, and the first shielding plate 310 is arranged between the air inlet 111 and the air outlet 121; the second shielding plate 320 is fixedly connected to the side of the first shielding plate 310. In this way, the first shielding plate 310 provides shielding between the air outlet 121 and the air inlet 111, and the second shielding plate 320 is fixedly connected to the side of the first shielding plate 310, so as to increase the shielding area and further reduce the risk of the discharged airflow flowing back into the air inlet cavity 110.

[0051] Specifically, the plane where the first shielding plate 310 is located and the plane where the second shielding plate 320 is located have an included angle.

[0052] Specifically, the angle is 60 degrees.

[0053] Optionally, two second shielding plates 320 are provided, and the two second shielding plates 320 are respectively fixedly connected to two opposite sides of the first shielding plate 310. In this way, a large number of second shielding plates 320 are provided, and the first shielding plate 310 and the second shielding plate 320 cooperate to increase the effective area of ​​guiding airflow, improve the guiding effect, and reduce the risk of the exhausted airflow flowing back into the air inlet cavity 110.

[0054] Combination Figure 5 As shown, optionally, a drainage hole 400 is provided at one end of the air duct body 100. In this way, since one end of the exhaust port 121 and the air inlet 111 of the air duct body 100 needs to extend to the outside through the wall, the other end is connected to the indoor unit of the fresh air air conditioner, so that the fresh air air conditioner discharges the indoor air through the exhaust cavity 120 to the outside through the air duct assembly, and introduces the outdoor air into the room from the air inlet cavity 110. When it rains at one end of the air duct body 100 located outdoors, water will enter the exhaust cavity 120 from the exhaust port 121 and enter the air inlet cavity 110 from the air inlet 111. The fresh air air conditioner is easy to suck water into the fresh air air conditioner when the fresh air function is running. By setting the drainage hole 400 on the air duct body 100, the water in the air duct body 100 can be discharged in time, thereby reducing the risk of sucking water into the fresh air air conditioner.

[0055] Optionally, a plurality of drain holes 400 are provided, wherein a portion of the drain holes 400 are communicated with the exhaust cavity 120, and the remaining portion of the drain holes 400 are communicated with the air inlet cavity 110. In this way, by providing a plurality of drain holes 400, water in the exhaust cavity 120 and the air inlet cavity 110 can be discharged in time, thereby reducing the risk of water being sucked into the fresh air air conditioner.

[0056] Specifically, two drain holes 400 are provided, one of which is communicated with the exhaust cavity 120, and the other is communicated with the air inlet cavity 110. In this way, by providing two drain holes 400, water in the exhaust cavity 120 and the air inlet cavity 110 can be discharged in time, thereby reducing the risk of water being sucked into the fresh air air conditioner.

[0057] Optionally, the flow rate of the air inlet chamber 110 is greater than the flow rate of the air outlet chamber 120. In this way, the flow rate of the air inlet chamber 110 is greater than the flow rate of the air outlet chamber 120, so that the amount of air entering the room through the air inlet chamber 110 is greater than the amount of air discharged to the outside by the air outlet chamber 120, so that the indoor pressure is higher than the outdoor pressure, avoiding the inhalation of untreated outdoor air from gaps such as door gaps and window gaps, and improving the quality of indoor air.

[0058] Optionally, the flow rate of the exhaust chamber 120 is less than or equal to seven eighths of the flow rate of the air inlet chamber 110, and greater than or equal to one fifth of the flow rate of the air inlet chamber 110. In this way, when the flow rate of the exhaust chamber 120 is greater than seven eighths of the flow rate of the air inlet chamber 110, the pressure difference between indoor and outdoor is too small, and there is a high risk that untreated outdoor air enters the indoor space from gaps such as door gaps and window gaps. When the flow rate of the exhaust chamber 120 is less than one fifth of the flow rate of the air inlet chamber 110, the pressure difference between indoor and outdoor is too large, and the speed at which indoor air flows out of the outdoor space from gaps such as door gaps and window gaps is faster, and there is a greater risk of generating wind noise. Therefore, the range in which the flow rate of the exhaust chamber 120 is less than or equal to seven eighths of the flow rate of the air inlet chamber 110 and greater than or equal to one fifth of the flow rate of the air inlet chamber 110 is more reasonable, which reduces the risk of untreated outdoor air entering the indoor space from gaps such as door gaps and window gaps, and also reduces the risk of generating wind noise.

[0059] Specifically, the flow rate of the exhaust cavity 120 is equal to four sevenths of the flow rate of the inlet cavity 110. 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.

[0060] Specifically, the flow rate of the exhaust cavity 120 is equal to one quarter of the flow rate of the inlet cavity 110. 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.

[0061] Combination Figure 6 As shown, optionally, the outer side wall of the duct body 100 is provided with a reinforcement member 500. In this way, the structural strength of the duct body 100 is improved by the reinforcement member 500.

[0062] Optionally, the reinforcement member 500 includes: a spiral reinforcement rib 510 and / or a reinforcement groove 520. In this way, when the outer side wall of the duct body 100 is provided with a spiral reinforcement rib 510, the structural strength of the duct body 100 is improved by the spiral reinforcement rib 510. When the outer side wall of the duct body 100 is provided with a reinforcement groove 520, the structural strength of the duct body 100 is improved by the reinforcement groove 520. When the duct body 100 is provided with both the spiral reinforcement rib 510 and the reinforcement groove 520, the structural strength of the duct body 100 is further improved.

[0063] Optionally, the partition plate 200 is made of a heat-conducting material. In this way, heat is exchanged between the air inlet cavity 110 and the air outlet cavity 120 through the partition plate 200, which can reduce the temperature difference between the airflow in the air inlet cavity 110 and the airflow in the air outlet cavity 120.

[0064] It can be understood that when the outdoor temperature is high and the fresh air air conditioner is turned on in cooling mode, the temperature of the air discharged through the exhaust cavity 120 is lower than the air introduced through the air inlet cavity 110 due to the low indoor air temperature. At this time, the air in the exhaust cavity 120 and the air in the air inlet cavity 110 exchange heat through the partition 200, which can reduce the temperature of the air in the exhaust cavity 120 and reduce the cooling capacity of the fresh air air conditioner.

[0065] Optionally, the partition plate 200 is made of brass. In this way, the partition plate 200 made of brass has better thermal conductivity, and the air inlet chamber 110 and the air outlet chamber 120 exchange heat through the partition plate 200, which can reduce the temperature difference between the airflow in the air inlet chamber 110 and the airflow in the air outlet chamber 120.

[0066] Optionally, the spiral axis of the partition 200 coincides with the axis of the air duct body 100. In this way, the air inlet cavity 110 and the air outlet cavity 120 separated by the partition 200 have relatively consistent flow areas at different positions of the air inlet cavity 110 and the air outlet cavity 120, making the air flow smoother.

[0067] Combination Figure 7 As shown, optionally, the air duct assembly further includes: a connecting pipe 610 and a connecting plate 620. One end of the connecting pipe 610 is connected to the other end of the air duct body 100 where the air inlet 111 is provided; a connecting plate 620 is provided inside the connecting pipe 610, and the connecting plate 620 extends upward along the axis of the connecting pipe 610 to divide the connecting pipe 610 into an inflow chamber 611 and an outflow chamber 612; wherein, one end of the connecting plate 620 is fixedly connected to one end of the shelf, so that the inflow chamber 611 is connected to the air inlet chamber 110, and the outflow chamber 612 is connected to the exhaust chamber 120. In this way, since the partition 200 is spirally arranged along the axis of the air duct body 100, the risk of the partition 200 being bent and damaged is relatively high during the process of bending the air duct body 100. Therefore, the connecting pipe 610 is arranged to be connected to the air duct body 100, and when bending is required, the connecting pipe 610 is bent first.

[0068] Specifically, the shape of the cross section of the connecting plate 620 is the same as the shape of the cross section of the partition plate 200 .

[0069] Optionally, the connecting plate 620 is bent toward one side of the inflow cavity 611 and / or the outflow cavity 612. In this way, when the connecting plate 620 is bent toward the inflow cavity 611, a margin is provided for the bending deformation and tensile deformation of the connecting plate 620 in the connecting tube 610. In the process of bending and laying the connecting tube 610, the bent connecting plate 620 can follow the bending of the connecting tube 610 and produce an adaptive deformation, reducing the risk of deformation and damage of the connecting plate 620 after the connecting tube 610 is bent, and reducing the difficulty of installation. In the case where the connecting plate 620 is bent toward the outflow cavity 612, a margin is provided for the bending deformation and tensile deformation of the connecting plate 620 in the connecting tube 610. In the process of bending and laying the connecting tube 610, the bent connecting plate 620 can follow the bending of the connecting tube 610 and produce an adaptive deformation, reducing the risk of deformation and damage of the connecting plate 620 after the connecting tube 610 is bent, and reducing the difficulty of installation. When the connecting plate 620 is bent toward both the inflow cavity 611 and the outflow cavity 612, a margin is provided for the bending deformation and tensile deformation of the connecting plate 620 in the connecting tube 610. During the bending and laying process of the connecting tube 610, the bent connecting plate 620 can follow the bending of the connecting tube 610 and produce an adaptive deformation, thereby reducing the risk of deformation and damage of the connecting plate 620 after the bending of the connecting tube 610 and reducing the difficulty of installation.

[0070] It can be understood that when the connecting plate 620 is bent toward both the inflow cavity 611 and the outflow cavity 612, a portion of the connecting plate 620 is bent toward the outflow cavity 612, and the remaining portion is bent toward the inflow cavity 611. For example, the upper half of the connecting plate 620 is bent toward the exhaust direction, and the lower half of the connecting plate 620 is bent toward the inflow cavity 611.

[0071] Specifically, when the connecting plate 620 is bent toward one side of the outflow cavity 612, the cross section of the connecting plate 620 is C-shaped. In this way, a margin is provided for the bending deformation and tensile deformation of the connecting plate 620 in the connecting tube 610. During the bending and laying process of the connecting tube 610, the bent connecting plate 620 can follow the bending of the connecting tube 610 and produce an adaptive deformation, thereby reducing the risk of deformation and damage of the connecting plate 620 after the connecting tube 610 is bent, and reducing the difficulty of installation.

[0072] For example, when the connection plate 620 is bent toward the outflow cavity 612 , a line connecting two sides of the connection plate 620 connected to the connection tube 610 may intersect the axis of the connection tube 610 at right angles.

[0073] Combination Figure 8As shown, specifically, when a portion of the connecting plate 620 is bent toward the outflow cavity 612 and the rest of the connecting plate 620 is bent toward the inflow cavity 611, the cross section of the connecting plate 620 is S-shaped. In this way, a margin is provided for the bending deformation and tensile deformation of the connecting plate 620 in the connecting tube 610. During the bending and laying process of the connecting tube 610, the bent connecting plate 620 can follow the bending of the connecting tube 610 and produce an adaptive deformation, thereby reducing the risk of deformation and damage of the connecting plate 620 after the connecting tube 610 is bent, and reducing the difficulty of installation.

[0074] In some embodiments, the air conditioner includes: a duct assembly as in the above embodiments.

[0075] The air conditioner provided in this embodiment includes the duct assembly in the above embodiment, and the duct body 100 is provided with a partition 200, and the partition 200 extends upward along the axial direction of the duct body 100 to divide the duct body 100 into an air inlet chamber 110 and an air outlet chamber 120, and the partition 200 is spirally arranged along the axial direction of the duct body 100. When the air conditioner exhausts air to the outside through the air outlet chamber 120, the airflow forms a spiral airflow under the guidance of the air outlet chamber 120 and is discharged to the outside. The diffusion of the spiral airflow is better, and the gas discharged to the outside is more dispersed, reducing the risk of the airflow in the air outlet chamber 120 flowing back to the air inlet chamber 110.
