Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a chassis drainage structure and an air conditioner. Background Art

[0002] With the development of social economy, air conditioning has become an important part of people's office and life. Air conditioners generally include indoor units and outdoor units. In daily use of air conditioners, since the air outlet of the outdoor unit is exposed to the outside, rainwater will enter the inside of the outdoor unit on rainy days. In particular, for the top-outlet outdoor unit, the air outlet is opened upward, and a large amount of rainwater will enter the inside of the box on rainy days.

[0003] like Figures 1-2 As shown, in the prior art, a drain port 2 is provided on the chassis 1 of the outdoor unit, and a water outlet 3 is provided at the drain port 2. Impurities such as dust, leaves, and bird droppings can easily fall into the air duct from the grille of the outdoor unit, especially the grille on the top cover of the top-outlet outdoor unit, and accumulate on the chassis 1. Over the years, impurities gradually accumulate in the water outlet of the chassis, causing blockage (similar to the blockage of the kitchen sewer), resulting in the inability of water on the chassis to be discharged through the water outlet, causing water to overflow from other positions of the chassis. In addition, when the inside of the water outlet is blocked, it is difficult to remove impurities in the channel because the water outlet channel is "L" shaped, resulting in a poor user experience. Summary of the invention

[0004] The main problem solved by the present invention is that in the prior art, the drainage assembly on the chassis of the outdoor unit is easily blocked, causing water to overflow from other positions of the chassis, and impurities are difficult to clean and discharge.

[0005] To solve the above problems, the present invention provides a chassis drainage structure, including a chassis and a drainage component, wherein the drainage component is arranged on the chassis, a drainage nozzle is arranged on the drainage component, a filtering device is arranged on the drainage component, and / or the drainage channel in the drainage nozzle is designed to be linear.

[0006] The chassis drainage structure described in the present application has a reasonable structure, is easy to clean and assemble, greatly reduces the probability of blockage of the drain nozzle, ensures the reliability of the chassis drainage of the outdoor unit, ensures that the outdoor unit can operate normally, reliably and safely, and improves the user experience.

[0007] Preferably, the filtering device is a filter screen or a retaining rib structure, which can filter the water flowing from the chassis to the drainage assembly. The net or retaining rib structure is set to block foreign matter in the water flowing from the chassis to the drainage nozzle, so as to prevent the drainage nozzle from being blocked by foreign matter, ensure the reliability of filtering, and facilitate production and cleaning.

[0008] Preferably, an assembly groove is provided on the chassis, and the drainage assembly is detachably fixed in the assembly groove.

[0009] This setting facilitates the disassembly and cleaning of the drainage assembly. When there are too many impurities inside the chassis and cleaning is required, the drainage assembly can be removed from the assembly groove, and the impurities filtered by the filter device on the chassis and the drainage assembly can be cleaned. There is no need to worry about blockage in the drainage assembly pipe. The cleaning efficiency and cleaning effect are better than conventional water outlets.

[0010] Furthermore, the cross-section of the assembly groove is circular or polygonal, and its cross-sectional area is not less than 5 cm 2 .

[0011] This setting increases the cross-sectional area of ​​the assembly groove, making the drainage area of ​​the drainage box on the drainage assembly much larger than that of a conventional water outlet. Even if a local position on the filter device is blocked by impurities, it will not affect the drainage effect, further greatly improving the drainage reliability of the drainage structure described in the present invention.

[0012] Furthermore, the drainage assembly includes a drainage box, the drainage nozzle is arranged at the lower end of the drainage box, and the filtering device is arranged above the drainage nozzle.

[0013] This arrangement ensures the reliability of the filter device in filtering impurities on the chassis.

[0014] Furthermore, a receiving cavity is provided on the drainage box, and the filtering device is provided in the receiving cavity, or the filtering device is provided on the upper end surface of the receiving cavity.

[0015] This setting discloses a structural form of a drainage component, so that water and impurities flowing through the drainage component are first filtered by a filtering device before entering the accommodating cavity on the drainage box, thereby preventing impurities from entering the interior of the drainage box, further improving the reliability of the drainage component in filtering impurities, and facilitating the cleaning of the drainage component.

[0016] Furthermore, the filtering device and the drainage box are integrally formed.

[0017] This arrangement improves the applicability of the present invention and further improves the assembly efficiency of the drainage component on the basis of improving the water discharge effect of the chassis.

[0018] Furthermore, the drainage channel is arranged along the vertical direction.

[0019] This arrangement further improves the drainage reliability of the drainage structure of the present invention.

[0020] Furthermore, a buckle device is provided on the upper end surface of the drainage box, and the buckle device is used to buckle and connect the drainage box with the assembly groove.

[0021] This arrangement realizes the detachable assembly and fixation of the drainage box and the assembly groove by adopting a snap connection, which is convenient for processing and production, has a stable connection, and is convenient for assembly and disassembly.

[0022] Furthermore, the buckle device includes at least two buckles, and the buckling directions of the two buckles are respectively arranged towards two different directions.

[0023] This arrangement further improves the stability and reliability of the snap-fit ​​connection between the drainage box and the assembly groove.

[0024] Furthermore, a limiting rib is arranged on the upper part of the drainage box, and the limiting rib and the buckle head of the buckle device together form the upper and lower limiting structures of the drainage assembly.

[0025] This arrangement facilitates that after the drainage component and the assembly groove are assembled in place, the buckle head of the buckle device and the limiting ribs together form an upper and lower limiting structure, further improving the stability of the assembly connection between the drainage component and the assembly groove.

[0026] Furthermore, the assembly groove is arranged on the water collecting plate on the chassis, and after the buckle device is assembled with the assembly groove, there is a gap between the connecting plate on the buckle device and the water collecting plate at the connecting position corresponding to the assembly groove.

[0027] This arrangement allows the drain component to be snap-connected to the assembly groove and, under the action of the snap device, complete the snap-in limiting in multiple directions, thereby preventing the drain component from being stuck after assembly, further improving the convenience of installing or disassembling the drain component and the assembly groove.

[0028] The present invention also discloses an air conditioner, comprising an indoor unit and an outdoor unit, wherein the outdoor unit is provided with the chassis drainage structure as described above.

[0029] Compared with the prior art, the chassis drainage structure and air conditioner of the present invention have the following advantages:

[0030] 1) The chassis drainage structure of the present invention can greatly reduce the probability of clogging of the drainage nozzle by arranging a filtering device on the drainage assembly assembled on the chassis, thereby ensuring the reliability of the chassis drainage of the outdoor unit, ensuring that the outdoor unit can operate normally, reliably and safely, and improving the user experience;

[0031] 2) The chassis drainage structure described in the present invention can not only reasonably set the assembly groove and the corresponding drainage components according to the spatial structure on the chassis, but also be applicable to the top-outlet outdoor unit or the side-outlet outdoor unit. It has a simple structure, is easy to clean, has a good anti-blocking effect, is easy to assemble, and can be widely used in the air-conditioning outdoor unit structure, with strong applicability.

[0057] As a preferred example of the present invention, the filter device 6 is a filter screen or a retaining rib structure, which can filter the water flowing from the chassis 1 to the drainage assembly, and can block foreign matter from flowing from the chassis 1 to the drainage nozzle 505, thereby preventing the drainage nozzle 505 from being blocked. This setting discloses a structure of a filter device, which ensures the reliability of the filter device 6 in filtering the water flowing to the drainage nozzle 505 on the drainage assembly 5, and is easy to produce and clean. Preferably, as an example of the present invention, the filter device 6 is a filter screen.

[0061] This arrangement discloses a structural form of a drainage component 5, so that water and impurities flowing through the drainage component are first filtered by the filter device 6 and then enter the accommodating cavity 501a on the drainage box 501, and then flow out through the drainage nozzle 505 provided at the lower end of the drainage box 501. This arrangement prevents impurities from entering the drainage box 501, further improves the reliability of the drainage component 5 in filtering impurities, and facilitates the cleaning of the drainage component 5.

[0062] Preferably, as a preferred example of the present invention, the cross section of the assembly groove 4 is circular or polygonal, and its cross-sectional area is not less than 5 cm 2 As an example of the present invention, the cross-section of the assembly groove 4 can be circular, or can be a polygonal structure such as a triangle, rectangle, square, regular polygon, irregular polygon, etc., so that the assembly groove 4 can be reasonably arranged according to the space reserved on the chassis 1, and the cross-sectional area of ​​the assembly groove 4 is set to be not less than 5cm 2 , preferably 10cm 2 ~100cm 2 Any value between, for example, 5cm 2 、8cm 2 , 10cm 2 、12cm 2 、15cm 2 、18cm 2 , 20cm 2 、25cm 2 、28cm 2 、30cm 2 、32cm 2 、35cm 2 , 50cm 2 、60cm 2 、70cm 2 、80cm 2 、90cm 2 This arrangement increases the cross-sectional area of ​​the assembly groove 4, so that the drainage area of ​​the drainage box 501 on the drainage assembly is much larger than that of a conventional water outlet.

Preferably, the filter device 6 is integrally formed with the drainage box 501, which facilitates the production and assembly of the drainage component 5, and further improves the assembly efficiency of the drainage component 5 on the basis of improving the water discharge effect of the chassis 1.

[0064] As an example of the present invention, the drainage box 501 and the assembly groove 4 can be detachably fixed by any fixing method such as screw connection, clamping connection, boss limitation or fixing with a third connecting member.

[0065] As an example of the present invention, the drainage nozzle 505 is arranged in a straight opening. Preferably, as a preferred example of the present invention, a buckle device 503 is arranged on the upper end surface of the drainage box 501, and the buckle device 503 is used to buckle and connect the drainage box 501 with the assembly groove 4.

[0066] This arrangement realizes the detachable assembly and fixation of the drainage box 501 and the assembly groove 4 by adopting a snap connection, which is convenient for processing and production, has a stable connection, and is convenient for assembly and disassembly.

[0067] Preferably, as a preferred example of the present invention, the snap device 503 includes at least two snaps, and the snap-in directions of the two snaps are respectively set in two different directions. When the drainage box 501 is snapped with the assembly groove 4, the drainage box 501 is first inserted into the assembly groove 4 from the lower side of the assembly groove 4 upwards. At this time, the snap device 503 is deformed by force and moves toward the center of the drainage box 501; then, the snap head of the snap device 503 passes through the assembly groove 4 and reaches the upper side of the assembly groove 4. At this time, the snap device 503 is no longer stressed and recovers its deformation. The snap head moves outward and is clamped with the upper end surface of the assembly groove 4, wherein the snap-in direction of the snap is the direction in which the snap device 503 shrinks inward when snapping and then recovers its deformation outward.

[0068] As an example of the present invention, the cross-section of the box wall of the drainage box 501 in the vertical direction is arc-shaped, such as a semicircular arc, or bent, such as a U-shape or a V-shape. Preferably, the box wall of the drainage box 501 includes a side wall 501b and a bottom wall 501c, the filter device 6 is arranged at the upper end of the side wall 501b, and the bottom wall 501c is arranged at the lower end of the side wall 501b, and the accommodating chamber 501a is surrounded by the filter device 6, the side wall 501b and the bottom wall 501c. The side wall 501b is a rectangular structure surrounded by four side panels. Preferably, the side wall 501b is vertically connected to the bottom wall 501c, or the side wall 501b is inclined and connected to the bottom wall 501c. Correspondingly, the assembly groove 4 is also arranged in a rectangular shape, and one or more buckles are arranged on the four side panels of the side wall 501b. After the buckles on the four side panels are snap-connected with the assembly groove 4, the drainage box 501 is limited in four directions of front, back, left and right. Fig.13 As indicated by the arrow in .

[0069] This arrangement further improves the stability and reliability of the snap-fit ​​connection between the drainage box 501 and the assembly groove 4 .

[0070] Preferably, the buckle on the buckle device 503 includes a buckle head and a connecting plate 504, the lower end surface of the connecting plate 504 is arranged on the upper end surface of the drainage box 501, and the upper end surface of the connecting plate 504 is connected to the buckle head.

[0071] This arrangement enables the snap joint of the snap device 503 to be snap-fitted and fixed after passing through the assembly slot 4, which is convenient for production and assembly.

[0072] As an example of the present invention, the drain nozzle 505 is arranged on the bottom wall 501c or the lower end of the side wall 501b, and a drainage channel 505a is arranged on the drain nozzle 505, and the drainage channel 505a is connected to the accommodating chamber 501a. Preferably, the drain nozzle 505 is arranged on the bottom wall 501c, and a transition arc is arranged at the connection between the drain nozzle 505 and the bottom wall 501c.

[0073] As an example of the present invention, Figures 7 to 11 As shown, a buckle is respectively provided on the two side panels in the length direction of the side wall 501b, which are the first buckle 503a and the third buckle 503c, and the clamping directions of the two buckles are both in the direction away from the accommodating cavity 501a; a buckle is also respectively provided on the two side panels in the width direction of the side wall 501b, which are the second buckle 503b and the fourth buckle 503d, and the clamping directions of the two buckles are also in the direction away from the accommodating cavity 501a.

[0074] Preferably, as a preferred example of the present invention, a limiting rib 502 is provided on the upper part of the drainage box 501. As an example of the present invention, the limiting rib 502 is provided at the circumference of the upper end of the drainage box 501, and the limiting rib 502 and the accommodating cavity 501a are respectively provided on both sides of the side wall 501b.

[0075] This arrangement facilitates that after the drain assembly 5 is assembled with the assembly groove 4, the buckle device 503 and the limiting rib 502 together form an upper and lower limiting structure, further improving the stability of the assembly connection between the drain assembly 5 and the assembly groove 4.

[0076] Preferably, as a preferred example of the present invention, the assembly groove 4 is arranged on the water collecting plate 101 on the chassis 1, and after the buckle device 503 is assembled with the assembly groove 4, there is a gap 7 between the connecting plate 504 on the buckle device 503 and the water collecting plate 101 at the connection position of the corresponding assembly groove 4. Preferably, the length of the gap 7 is H, and the value range of H is 0.1mm to 0.3mm.

[0077] This arrangement allows the drain component 5 to be snap-connected with the assembly groove 4 and, under the action of the snap device 503, complete the snap-in limiting in multiple directions, thereby preventing the drain component 5 from being stuck after assembly, further improving the convenience of installing or disassembling the drain component 5 and the assembly groove 4.

[0078] As an example of the present invention, the water collecting plate 101 is arranged at a lower position on the chassis 1. The condensation or rainwater collected on the chassis 1 will flow to the water collecting plate 101 under the action of the guide structure, and can flow to the drainage component 5 through the assembly groove 4 on the water collecting plate, and then flow out from the drainage nozzle 505 after filtering by the drainage component 5.

[0079] This arrangement further improves the reliability of drainage of the drainage assembly 5 on the chassis 1.

[0080] As an example of the present invention, the upper plane of the limiting rib 502 is flush with the upper plane of the filter device 6 and the upper plane of the side wall 501b.

[0081] This arrangement enables the drainage box 501 of the drainage assembly 5 to be arranged below the assembly groove 4, further ensuring the reliability of water flowing from the chassis 1 to the drainage assembly.

[0082] When assembled and used, the filtering device 6 is fixed on the drainage component 5;

[0083] S1: First, place the drainage assembly 5 under the chassis 1 and align it with the assembly groove 4 on the chassis 1;

[0084] S2: Extend the buckle device 503 on the drainage assembly 5 from bottom to top into the assembly groove 4;

[0085] S3: When the limiting rib 502 on the drainage component 5 abuts against the lower surface of the water collecting plate 101, the clamping joint of the snap device 503 just extends out of the assembly groove 4 and is clamped on the upper surface of the water collecting plate 101, and the limiting rib 502 cooperates with the clamping head of the snap device 503 to complete the limitation of the drainage component 5 and the assembly groove 4 in the upper and lower directions, and the assembly is completed.

[0086] When dismantling, just detach the buckle device 503 on the drainage assembly 5 from the assembly groove 4 .

[0087] In actual operation, it is necessary to first open the top cover of the outdoor unit or the opening structure on the side wall of the outdoor unit so that the user can touch the buckle device 503 on the drainage assembly 5.
