Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of air purification, and in particular to a fresh air inlet pipe and a method for using the same, a fresh air pipe assembly and an air conditioner. BACKGROUND

[0002] An air conditioner is usually provided with a fresh air inlet pipe for inhaling fresh air from the outside. In some application scenarios, for example, when there is a lot of rain outside, a large amount of rainwater will inevitably be mixed in when inhaling fresh air. The rainwater entering the inside of the air conditioner can easily cause damage to parts such as the blades of the fan, and also makes the air blown into the room have a large humidity, affecting the user experience.

[0003] To solve the above problems, the related art usually bends the part of the fresh air inlet pipe that extends outside the wall body downward. However, this inlet structure has the following problems. On the one hand, due to the size limitation of the channel in the wall body through which the fresh air inlet pipe passes, the bent part cannot pass directly, so the fresh air pipe can only be installed from the outside, resulting in a large installation difficulty. On the other hand, the inlet pipe designed by bending makes the fresh air only be inhaled from the side, that is, the direction of the inlet is perpendicular to the direction of the pipe, which produces a large wind loss and affects the efficiency of the inlet. SUMMARY

[0004] To overcome the problems in the related art, the present disclosure provides a fresh air inlet pipe and a method for using the same, a fresh air pipe assembly and an air conditioner.

[0006] Optionally, the fresh air pipe and the pipe running structure are respectively located on the left and right sides of the separation part, the two connecting positions of the pipe wall of the fresh air pipe and the separation part are respectively located at the upper part and the bottom part, and the drain part is arranged at the bottom part.

[0007] Optionally, the drain part is arranged at the two connecting positions of the pipe wall of the fresh air pipe and the separation part.

[0008] Optionally, the thinned connecting section is distributed on the other three sides of the drain part except the side of the fresh air inlet, the thinned connecting section connects the pipe wall of the fresh air pipe and the body of the drain part, and after the thinned connecting section is broken, the body of the drain part can be removed to form a drain gap.

[0009] Optionally, the extending length of the drainage gap accounts for 15% to 50% of the length of the fresh air duct, and / or the width of the drainage gap along the circumference of the fresh air duct accounts for 2% to 20% of the circumferential length of the fresh air duct.

[0010] Optionally, the pipe wall of the fresh air duct is provided with a stop rib outwardly protruding from the wall surface at a position close to the drainage portion, the stop rib extends along the length direction of the fresh air duct from the fresh air inlet to a direction away from the fresh air inlet, and the extending length of the stop rib is at least equal to the length of the drainage portion.

[0011] Optionally, a plurality of stop ribs are arranged along the circumference of the fresh air duct.

[0012] Optionally, the pipe passing structure comprises a first elastic arm and a second elastic arm oppositely arranged to enclose a receiving space with the partition portion, one end of the first elastic arm and the second elastic arm is fixedly connected with the partition portion, and the other end is formed as a free end with elasticity.

[0013] According to a second aspect of the embodiments of the present disclosure, a fresh air pipe assembly is provided, comprising a fresh air pipe and the fresh air inlet pipe of any one of the above, one end of the fresh air pipe is used to communicate with an air conditioner indoor unit, and the other end of the fresh air pipe communicates with the fresh air inlet pipe.

[0014] Optionally, the fresh air pipe communicates with the fresh air duct of the fresh air inlet pipe through an adapter pipe, wherein the adapter pipe comprises a first adapter port with a shape suitable for the fresh air pipe and a second adapter port with a shape suitable for the fresh air duct.

[0015] According to a third aspect of the embodiments of the present disclosure, an air conditioner is provided, comprising an air conditioner indoor unit and the fresh air pipe assembly.

[0016] According to a fourth aspect of the embodiments of the present disclosure, a use method of the fresh air inlet pipe of any one of the above is provided, the method comprising: removing the drainage portion body to form a drainage gap after breaking the thinned connecting section.

[0017] The technical scheme provided by the embodiments of the present disclosure can have the following beneficial effects: the tube body of the fresh air inlet pipe provided by the present disclosure is a straight pipe, so that the fresh air can enter the fresh air pipe in the axial direction.

DETAILED DESCRIPTION

[0027] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] Unless otherwise indicated, the orientation words such as "upper", "lower", "left", "right" are defined according to the directions indicated by the corresponding drawings, and "inner", "outer" refer to the inner and outer of the outline of the corresponding components themselves. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequential and important meanings.

[0029] It should be noted that all actions of obtaining signals, information or data in the present application are carried out in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the owner of the corresponding device.

[0030] As shown in Figures 1 to 4 The present disclosure provides a fresh air inlet pipe 1 for being arranged at the air inlet of a fresh air pipe 2 of an air conditioner. Specifically, the fresh air inlet pipe 1 includes a pipe body 11, which is a straight pipe and is divided by a partition 113 into a fresh air pipe 111 and a pipe running structure 112. The partition 113 can be a partition plate integrally formed with the pipe body 11. The fresh air pipe 111 is used for passing fresh air, i.e. under the action of a fan, a negative pressure is generated inside the fresh air pipe 111, so that outdoor fresh air is sucked into the fresh air pipe 111. The pipe running structure 112 is used for penetrating and fixing an indoor and outdoor unit connecting pipe or a drain pipe and the like.

[0031] In the process of installing the fresh air pipe, a channel needs to be preset in the wall 200 for the fresh air pipe to pass from the indoor to the outdoor. Due to the size limitation of the preset channel, the bending-shaped fresh air pipe in the related art cannot be installed from the indoor but only from the outdoor, which is difficult and unsafe. The pipe body 11 of the fresh air inlet pipe 1 of the present disclosure is a straight pipe with a small radial size, which can achieve the purpose of installation from the indoor, improve the installation efficiency, and due to the straight pipe, the air inlet direction is substantially perpendicular to the direction of the pipe, compared with the bending-shaped pipe in the related art, the wind loss caused by the impact of the fresh air on the pipe wall is reduced, thereby having a higher air inlet efficiency.

[0032] The fresh air pipe 111 has a fresh air inlet, i.e., an opening of the fresh air pipe 111 towards the outside of the wall 200 after installation. At least one of the circumferential positions of the pipe wall of the fresh air pipe 111 is provided with a drainage portion 1111, which extends from the fresh air inlet to the direction away from the fresh air inlet along the length direction of the fresh air pipe 111, and the drainage portion 1111 has a thinning connection section 11111. Here, "thinning" refers to the thickness of the pipe wall of the fresh air pipe 111, specifically, the thinning connection section 11111 is thinner than other positions of the pipe wall, so that it is easier to remove by breaking or the like, thereby forming a drainage gap 1113, which is convenient and fast to use.

[0033] For example, in the case of the pipe outlet mode without rainproof, the fresh air inlet pipe 1 can be directly installed. According to the case of the pipe outlet mode with rainproof, the drainage portion 1111 can also be quickly removed to obtain the drainage gap 1113. When part of the rainwater enters the fresh air pipe with the fresh air, the rainwater will slide under the action of gravity after impacting the inner wall of the fresh air pipe, until it is discharged from the drainage gap 1113 of the fresh air pipe, avoiding the rainwater from entering the air conditioner.

[0034] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: The pipe body 11 of the fresh air inlet duct 1 provided by this disclosure is a straight pipe, which allows fresh air to enter the fresh air duct 111 along the axial direction. Compared with related technologies with a bent structure that can only enter air from the side, it reduces the wind loss caused by the fresh air impacting the pipe wall, thereby having higher air intake efficiency. In addition, the straight pipe body 11 can realize the direct installation of fresh air ducts from indoors, reducing the difficulty of installation. Meanwhile, at least one drainage section 1111 is provided along the circumferential direction of the wall of the fresh air duct. The drainage section 1111 has a thinned connecting section 11111. The thinned connecting section 11111 makes the drainage section 1111 more likely to break than other parts of the duct wall, and thus be removed to form a drainage gap 1113, which is more convenient to use. When some rainwater enters the fresh air duct 111 with the fresh air, the rainwater will slide down under the action of gravity after impacting the inner wall of the fresh air duct 111, until it is discharged from the fresh air duct through the drainage gap 1113, thus preventing rainwater from entering the air conditioner.

[0035] Fresh air ducts have different outlet methods, such as Figure 1 As shown, the fresh air duct 111 and the duct structure 112 are located on the left and right sides of the partition 113, respectively. The wall of the fresh air duct 111 has two connection points with the partition 113, located at the top and bottom, respectively. This corresponds to the first outlet method of the fresh air duct. Figure 1 After rotating 180°, the second outlet method is obtained. In both outlet methods, the drainage section 1111 is located at the bottom to ensure that rainwater entering the fresh air duct 111 can be discharged. That is, in different outlet methods, one of the two connection points between the pipe wall of the fresh air duct 111 and the partition 113 serves as the bottom.

[0036] In other pipe outlet methods, for example, Figure 1 The fresh air intake duct 1 is rotated 90° counterclockwise, that is, the fresh air duct 111 and the duct structure 112 are located on the top and bottom sides of the partition 113 respectively. At this time, the drainage part 1111 is set at the bottom, that is, at any position between the pipe wall of the fresh air duct 111 and the two connection positions of the partition 113, preferably in the middle between the two connection positions.

[0037] Considering that fresh air ducts have different outlet methods during installation, and these different outlet methods determine the location of the drainage section 1111. In some implementations, such as Figure 1 As shown, drainage sections 1111 are provided at both connection points between the fresh air duct 111 and the partition 113. Thus, in the first outlet configuration, only the bottom drainage section 1111 needs to be removed to form the drainage opening 1113; conversely, in the second outlet configuration, only... Figure 1The drain section 1111 at the top can be removed. In this way, regardless of which outlet method is selected, the drain section 1111 can always be removed so that the drain opening 1113 formed is also facing the bottom, so that rainwater can be discharged from the fresh air intake duct 1, which has good versatility.

[0038] like Figures 1 to 3 As shown, the thinned connecting sections 11111 are distributed on the other three sides of the drainage section 1111, excluding the side with the fresh air inlet. Figure 3 At the location marked by the three dots in the middle, the thinned connecting section 11111 connects the pipe wall of the fresh air duct 111 to the drain body 11112. After the thinned connecting section 11111 breaks, the drain body 11112 can be removed to form a drain gap 1113.

[0039] When fresh air is drawn into the fresh air duct 111, it is drawn in with the air intake direction approximately parallel to the axis of the duct 111. This is in contrast to the bent fresh air ducts in related technologies, where the air intake direction is set at approximately 90° to the duct wall. This results in the fresh air impacting the duct wall due to its higher flow velocity, leading to greater air loss. It should be understood that although this application uses a straight duct body 11, making the air intake direction approximately parallel to the axis of the fresh air duct 111, in practice, the fresh air still enters the fresh air duct 111 at a certain angle, thus impacting the duct wall. For example… Figure 3 The two impact surfaces shown are the wall of the fresh air duct and the surface of the partition facing the fresh air duct, respectively. However, the impact on wind loss is still much smaller than that of fresh air ducts with a bent structure in related technologies.

[0040] Figure 3 The dashed arrows indicate the flow direction of rainwater after it hits the pipe wall. When fresh air mixed with rainwater hits the pipe wall of the fresh air duct 111, it can be considered to have two component forces. One component moves along the length of the fresh air duct 111, and the other component moves downward due to gravity. Therefore, under the action of the resultant force, the actual trajectory of the rainwater is approximately a parabola. Finally, it slides to the bottom of the fresh air duct 111 and is discharged from the drainage gap 1113.

[0041] With a drainage gap 1113 provided in the fresh air duct 111, a portion of the fresh air will actually be drawn into the fresh air duct 111 from the side. This portion of fresh air, together with the fresh air drawn in axially from the air inlet, will create a position with the greatest pressure gradient inside the fresh air duct 111. At this position with the greatest pressure gradient, gravity is overcome and the water will not slide down. Rainwater will inevitably be drawn into the air conditioner. Therefore, it is reasonable to configure the size of the drainage gap 1113 appropriately.

[0042] In some embodiments, the extension length of the drainage gap 1113 accounts for 15%-50% of the length of the fresh air duct 111. This ensures that the drainage gap 1113 is not too short, causing rainwater to pass over it before reaching the bottom of the fresh air duct 111, nor is it too long, exceeding the position of maximum pressure gradient and becoming ineffective. In other embodiments, the circumferential width of the drainage gap 1113 along the fresh air duct 111 is 2%-20% of the circumferential length of the fresh air duct 1111. This provides sufficient width for rainwater to drain smoothly, while avoiding excessive width that would hinder overcoming gravity and lengthen the downward trajectory of the rainwater. In still other embodiments, the extension length of the drainage gap 1113 accounts for 15%-50% of the length of the fresh air duct 111, and the circumferential width of the drainage gap 1113 along the fresh air duct 111 is 2%-20% of the circumferential length of the fresh air duct 111.

[0043] Here, we take the example of fresh air duct 111 and fresh air intake duct 1 having the same axial length. The length of fresh air intake duct 1 is 400 mm to 600 mm, the extension length of drainage notch 1113 is 100 mm to 200 mm, the equivalent inner diameter of fresh air duct 111 is 20 mm to 40 mm, and the width of drainage notch 1113 along the circumference of fresh air duct 111 is 10 mm to 30 mm.

[0044] As explained earlier, lateral air intake is undesirable because it leads to wind loss. Figures 1 to 3 As shown, a stop rib 1112 protruding outward from the wall of the fresh air duct 111 near the drain section 1111 is provided. The stop rib 1112 extends along the length of the fresh air duct 111 from the fresh air inlet in a direction away from the fresh air inlet, and the extension length of the stop rib 1112 is at least equal to the length of the drain section 1111. The stop rib 1112 serves both as a rainproof and airflow guide. Specifically, as shown... Figure 3 As indicated by the dashed arrow, when some fresh air is directed laterally towards the fresh air duct 111, the baffle 1112 will block some of the fresh air from entering through the drainage opening 1113. This reduces the amount of rainwater mixed with the fresh air entering the fresh air duct 111, and also reduces the amount of lateral fresh air, making it easier for rainwater inside the fresh air duct 111 to drain under gravity (without having to overcome the resistance of the fresh air entering through the opening 1111). In addition, rainwater can drain from the fresh air duct 1111 along the baffle 1112 under gravity. Optionally, the baffle 1112 can be configured to extend parallel to the partition 113, which provides a larger blocking area and makes it easier for rainwater to slide off.

[0045] Furthermore, such as Figures 1 to 3As shown, the stop ribs 1112 are arranged in multiple rows along the circumference of the fresh air duct 111, so that rainwater can be stopped at multiple positions of the wall of the fresh air duct 111, thereby further improving the stopping effect. In addition, one of the multiple stop ribs 1112 closest to the drainage gap 1113 is formed as a side edge of the outwardly folded drainage gap 1113, and the stop rib 1112 has the effect of more smoothly draining rainwater inside the fresh air duct 111 in addition to the stopping effect.

[0046] In some embodiments, as shown in Figures 1 to 3 As shown, the pipe running structure 112 can be an open loop structure or a closed loop structure. Taking the open loop structure as an example, the pipe running structure 112 includes a first elastic arm 1121 and a second elastic arm 1122 oppositely arranged to form a containing space 1123 with the partition 113. One end of the first elastic arm 1121 and the second elastic arm 1122 is fixedly connected to the partition 113, and the other end is formed as a free end with elasticity, so as to adapt to different sizes of pipes and be able to clamp the pipes under the action of elastic force after the pipes are arranged, thereby playing a role in fixing the pipes. The first elastic arm 1121 and the second elastic arm 1122 can be configured in a circular arc shape protruding radially outward, thereby providing a larger containing space. In addition, the first elastic arm 1121 and the second elastic arm 1122 are integrally formed with the partition 113, thereby improving the connection strength of the two. Furthermore, the entire fresh air inlet pipe 1 is integrally formed by injection molding or the like, thereby improving the structural strength of the entire fresh air inlet pipe 1. The closed loop structure is similar to the fresh air duct 111, which will not be described here.

[0047] According to a second aspect of the embodiments of the present disclosure, as shown in Figure 2 and Figure 4 A fresh air pipe assembly is provided, which includes the fresh air inlet pipe 1 in any of the above embodiments and a fresh air pipe 2. One end of the fresh air pipe 2 is used to communicate with an indoor unit of an air conditioner, and the other end of the fresh air pipe 2 communicates with the fresh air inlet pipe 1.

[0048] In some embodiments, as shown in Figure 4 As shown, the fresh air pipe 2 communicates with the fresh air duct 111 of the fresh air inlet pipe 1 through an adapter pipe 3, wherein the adapter pipe 3 includes a first adapter port 31 shaped to be adapted to the fresh air pipe 2 and a second adapter port 32 shaped to be adapted to the fresh air duct 111. For example, the fresh air pipe 2 can be a circular pipe for providing the largest flow area, and the fresh air duct 111 is a semicircular pipe. In this configuration, the fresh air pipe 2 and the fresh air inlet pipe 1 cannot be directly fitted and installed, and therefore the adapter pipe 3 is designed, i.e., one end of the adapter pipe 3 is the circular first adapter port 31, and the other end is the semicircular second adapter port 32. The adapter pipe 3 can be in the form of interference fitting with the fresh air pipe 2 and the fresh air duct 111, and the position of the interference fitting can be fixed by a pre-provided adhesive.

[0049] According to a third aspect of the embodiments of the present disclosure, as shown in Figure 5 The air conditioner is provided with the new air duct assembly in any of the above embodiments and has all the beneficial effects thereof, which will not be repeated here.

[0050] According to a fourth aspect of the embodiments of the present disclosure, a use method of the new air inlet duct 1 in any of the above embodiments is provided. The use method comprises: removing the drainage portion body 11112 to form the drainage gap 1113 after the thinned connection section 11111 is broken. Since the thinned connection section 11111 is thinner than other positions of the duct wall, it is easier to remove by breaking and the like, thereby forming the drainage gap 1113, which is convenient and fast to use. In addition, in the embodiment in which the drainage portion 1111 is arranged at two positions where the duct wall of the new air duct 111 and the partition portion 113 are connected, by arranging the thinned connection 11111, no matter which type of outlet duct is selected, the drainage portion 1111 can always be removed towards the bottom, and the drainage gap 1113 formed thereby is also towards the bottom, so as to drain rainwater out of the new air inlet duct 1, which has good versatility.

[0051] Other embodiments of the present disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the present disclosure. The present disclosure is intended to cover any variations, uses or adaptive changes of the present disclosure following the general principles thereof and including those expressly stated or implied herein.
