Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning condensate drainage, and in particular to a pipe assembly for air-conditioning condensate drainage. Background Art

[0002] Condensation water will be generated during the use of air conditioners, and it is necessary to discharge the condensation water in time. If the condensation water of the air conditioner is not discharged smoothly, it may first cause the indoor unit of the air conditioner to drip, and it may also cause the air conditioner to not operate normally. Therefore, the discharge of condensation water of the air conditioner is very critical.

[0003] In the prior art, when more than two air conditioners need to discharge condensate, the air conditioner condensate drain hose is usually inserted into the inclined three-way pipe fitting, and the condensate of multiple air conditioners is collected and discharged through the inclined three-way pipe fitting. When in use, in order to ensure that the drain hose can be firmly inserted into the inclined three-way pipe fitting, the drain hose usually needs to be inserted for a longer part.

[0004] However, the longer the portion of the drain hose inserted into the inclined tee fitting is, the more likely the end of the drain hose will come into contact with the inner wall of the inclined tee fitting and be squeezed and damaged; and when multiple drain hoses need to use the inclined tee to drain condensate, since the number of pipe openings on the inclined tee fitting for inserting the air-conditioning condensate drain hoses is fixed, multiple air-conditioning condensate drain hoses are required to share the pipe opening on the inclined tee fitting, which makes it more likely that the air-conditioning condensate drain hoses will be squeezed and damaged. Summary of the invention

[0005] In order to improve the problem that multiple drain hoses are easily damaged when draining water through an inclined three-way pipe fitting, the present application provides a pipe fitting combination for draining air-conditioning condensate water.

[0006] The present application provides a pipe assembly for draining condensed water from an air conditioner, which adopts the following technical solution:

[0007] A pipe fitting combination for draining condensate water from an air conditioner comprises a first pipe fitting and a second pipe fitting which are used in combination, wherein the first pipe fitting has a water inlet end and a drainage end, the water inlet end is communicated with the drainage end and are respectively located at two ends of the first pipe fitting; the first pipe fitting also has a first connecting end, the first connecting end is communicated with both the water inlet end and the drainage end, and the orientation of the first connecting end is perpendicular to the orientation of the water inlet end; the second pipe fitting has a first insertion end and a second connecting end, the first insertion end is communicated with the second connecting end, the orientation of the first insertion end is perpendicular to the orientation of the second connecting end, and the second connecting end can be connected and communicated with the first connecting end.

[0008] By adopting the above technical solution, the first pipe fitting and the second pipe fitting are connected between the first connecting end and the second connecting end to form a pipe fitting combination, which can be used for two or more drainage hoses to be plugged in; when the drainage hose is inserted and fixed at the first insertion end, the end of the drainage hose inserted into the water inlet end is not easy to contact and be squeezed with the inner cavity wall of the pipe fitting, so the degree of mutual squeezing between the ends of the multiple drainage hoses inserted into the first water inlet end will also be reduced, thereby reducing the probability of multiple drainage hoses being squeezed and damaged during use.

[0009] Optionally, a plurality of third pipe fittings are also included, each of which has a second insertion end and two third connecting ends, the two third connecting ends are respectively located at both ends of the third pipe fitting, the orientation of the second insertion end is perpendicular to the orientation of the third connecting end, and the third connecting end can be connected to the first connecting end and the second connecting end.

[0010] By adopting the above technical solution, after the first connecting end, the second connecting end and the third connecting end are connected in pairs, the first pipe fitting, the second pipe fitting and the plurality of third pipe fittings can form a new pipe fitting combination for plugging in two or more drainage hoses; the number of the third pipe fittings is determined according to the number of the drainage hoses, so that each drainage hose has a corresponding water inlet end for the drainage hose to be inserted on the new pipe fitting combination, and one water inlet end corresponds to one drainage hose, which can effectively avoid the situation where multiple drainage hoses are inserted into the same water inlet end, thereby further reducing the probability of multiple drainage hoses being squeezed and damaged during use.

[0011] Optionally, it also includes a plurality of connecting components, and the first pipe fitting, the second pipe fitting and the third pipe fitting can be connected to each other through the connecting components; the connecting component includes a pipe body and two connecting tubes, and the two connecting tubes are respectively sleeved on the two ends of the pipe body, and the outer sides of the two ends of the pipe body are provided with sliding grooves along their own axial directions, and the ends of the connecting tubes have sliding parts that are compatible with the sliding grooves, and the connecting tubes can slide and rotate relative to the pipe body; the first connecting end, the second connecting end and the third connecting end are all provided with threads, and the inner side wall of the connecting tube also has matching threads.

[0012] By adopting the above technical scheme, the connecting assembly is used to connect different pipe fittings. After controlling the connecting tube to slide outward to the extreme position, the connecting tube is controlled to rotate so that the connecting tube and the corresponding connecting end thread cooperate to form a connection; after connecting both ends of the connecting assembly to different pipe fittings by the same method, in order to facilitate the installation of the pipe assembly, the staff can control the connecting tube to rotate relative to the pipe body, so that the water inlet ends of different pipe fittings face the same direction or meet other positional relationships, which is convenient for installation operations; and when removing some pipe fittings from the pipe assembly, it is only necessary to release the threaded cooperation between the connecting tube and the pipe fitting, and the required operating space is small, making the operation more convenient and quick.

[0013] Optionally, the connecting assembly also includes two abutments and two first elastic members, the two abutments are respectively located at the two ends of the tube body, the abutments can slide relative to the tube body, the sliding direction of the abutments is parallel to the axis of the tube body, and the first elastic member drives the abutments to slide in a direction away from the other abutment.

[0014] By adopting the above technical solution, after the connecting tube and the connecting end of the pipe fitting are threadedly matched, the abutment will be pressed against the connecting end under the action of the first elastic member, and the tighter the threaded match between the connecting tube and the connecting end, the stronger the pressing effect between the abutment and the connecting end will be, which can improve the sealing of the pipe fitting combination and reduce the probability of liquid seeping out of the gap between the connecting tube and the connecting end.

[0015] Optionally, the connecting assembly further comprises a plurality of dirt cleaning members and a plurality of second elastic members, the dirt cleaning members being slidably connected to the tube body, and the sliding direction of the dirt cleaning members being perpendicular to the axis of the tube body, and the second elastic members driving the dirt cleaning members to slide in a direction away from the interior of the tube body; a plurality of clearance grooves for the dirt cleaning members to slide into are provided on the inner side wall of the sliding portion, and when the sliding portion abuts against the groove wall of the sliding groove close to one end of the abutting member, when the tube body rotates relative to the connecting tube, the end of the dirt cleaning member away from the connecting tube can enter and exit the interior of the tube body.

[0016] By adopting the above technical solution, when the give way groove is aligned with the cleaning piece, the second elastic piece will drive the cleaning piece to slide, so that one end of the cleaning piece enters the give way groove and abuts against the groove wall of the give way groove, and the other end slides out of the interior of the tube body; when the give way groove is not aligned with the cleaning piece, the sliding part will squeeze the cleaning piece and drive the cleaning piece to overcome the force of the second elastic piece to slide, so that the end enters the interior of the tube body; when the tubes are used in combination, the tube body is controlled to rotate relative to the two connecting tubes, so that a plurality of cleaning pieces can be controlled to slide back and forth, and the reciprocating sliding of the cleaning pieces can cause the dirt attached to the inner wall of the tube body to fall off, thereby reducing the probability of blockage of the tube body due to accumulation of dirt.

[0017] Optionally, the end of the cleaning member away from the connecting tube has an impact portion, and after the second elastic member drives the cleaning member to slide in a direction away from the inside of the tube body, the impact portion impacts the tube body to generate vibration.

[0018] By adopting the above technical solution, when the pipe fittings are used in combination and the pipe body rotates relative to the two connecting tubes, while the second elastic member drives the cleaning member to slide, the impact part will collide with the pipe body, so that the liquid inside the pipe body is affected by the vibration, thereby making it easier for the dirt attached to the inner wall of the pipe body to fall off, further reducing the probability of blockage of the pipe body due to the accumulation of dirt.

[0019] Optionally, the connecting assembly further comprises two rotating members, which are respectively arranged at two ends of the tube body, the rotating members are rotatably connected to the tube body, the abutting members are slidably connected to the rotating members, and the first elastic member is located inside the rotating members.

[0020] By adopting the above technical solution, the rotating part can make the relative rotation between the connecting tube and the pipe body smoother, reduce the probability of scratches and wear on the surfaces of the two caused by the relative rotation between the two, and facilitate the staff to disassemble and assemble the pipe combination.

[0021] Optionally, the tube body has a protrusion between the two sliding grooves for facilitating the control of the rotation of the tube body relative to the connecting tube.

[0022] By adopting the above technical solution, it is convenient for workers to use tools such as wrenches or manually control the rotation of the pipe body relative to the connecting pipe.

[0023] Optionally, when the connecting tube slides until the sliding portion abuts against the groove wall of the sliding groove close to one end of the other sliding groove, the end of the connecting tube away from the sliding portion is located on the side of the adjacent abutment located at one end outside the tube body close to the other abutment.

[0024] By adopting the above technical solution, when removing a certain pipe fitting, the pipe fitting can be removed after the connecting tubes at both ends of the pipe fitting are threadedly uncoupled from it; when removing a certain connection assembly, the connection assembly can be removed after the two connecting tubes of the connection assembly are threadedly uncoupled from the corresponding pipe fitting; there is no need to operate other parts of the pipe fitting assembly, which further facilitates the disassembly and assembly of the pipe fitting assembly.

[0025] Optionally, a plurality of the cleaning members are distributed in a circular array on the tube body, a plurality of the making way grooves are also distributed in a circular array on the connecting tube, and the spacing between adjacent cleaning members is 1 / 2 of the spacing between adjacent making way grooves.

[0026] By adopting the above technical solution, when the pipe fittings are used in combination, half of the cleaning pieces keep their ends entering the interior of the pipe body, and the other half of the cleaning pieces keep their ends entering the give way grooves; the ends of the cleaning pieces entering the interior of the pipe body can make it easier for dirty substances to adhere to positions nearby, thereby achieving a better cleaning effect when the pipe body is rotated to clean the interior of the pipe body.

[0043] The overall structure of the second pipe fitting 2 is L-shaped, and the second pipe fitting 2 has two ports that are connected to each other, namely, a first insertion end 21 and a second connection end 22. The orientation of the first insertion end 21 is perpendicular to the orientation of the second connection end 22, the pipe diameter of the first insertion end 21 is the same as the pipe diameter of the second connection end 22, and the end of the second connection end 22 has a thread on the outer surface. In this embodiment, the second pipe fitting 2 is preferably a right-angle elbow, and the pipe diameters of the first insertion end 21 and the second connection end 22 are preferably both 32 mm.

[0044] The overall structure of the third pipe fitting 3 is also T-shaped, and the third pipe fitting 3 has three ports that are interconnected, namely a second insertion end 31 and two third connection ends 32. Among them, the two third connection ends 32 are respectively located at the two ends of the third pipe fitting 3, and the directions of the two third connection ends 32 are located on the same straight line; and the second insertion end 31 is located on one side of the third pipe fitting 3, and the direction of the second insertion end 31 is perpendicular to the direction of the third connection end 32. The second insertion end 31 and the two third connection ends 32 have the same diameter, and the end of the third connection end 32 has a thread on the outer surface. In this embodiment, the third pipe fitting 3 is preferably a right-angle tee with the same diameter, and the diameters of the second insertion end 31 and the third connection end 32 are preferably 32 mm.

[0045] The pipe fittings have different combinations according to different usage conditions:

[0046] When the number of drainage hoses is 1, only one first pipe fitting 1, one second pipe fitting 2 and one connecting assembly 4 are needed to form a suitable pipe fitting combination. After the first connecting end 13 of the first pipe fitting 1 and the second connecting end 22 of the second pipe fitting 2 are connected through the connecting assembly 4, the first insertion end 21 of the second pipe fitting 2 can be inserted and installed for the drainage hose;

[0047] When the number of drainage hoses is n (n≥2), one first pipe fitting 1, one second pipe fitting 2, (n-1) third pipe fittings 3 and n connection components 4 are required to form a suitable pipe fitting combination. After the first connection end 13 of the first pipe fitting 1 is connected to the third connection end 32 of the third pipe fitting 3 through the connection component 4, the third connection end 32 of the adjacent third pipe fitting 3 is connected through the connection component 4, and the third connection end 32 of the third pipe fitting 3 is also connected to the second connection end 22 of the second pipe fitting 2 through the connection component 4, the first insertion end 21 of the second pipe fitting 2 and the second insertion ends 31 of (n-1) third pipe fittings 3 can be inserted and installed with n drainage hoses. In the accompanying drawings, the pipe fitting combination is shown in the case of n=2.

[0048] Reference Figure 3 and Figure 4The connection assembly 4 includes a tube body 41 and two connection tubes 42, and the two connection tubes 42 are respectively sleeved at the two ends of the tube body 41. The outer surface of the tube body 41 is provided with two sliding grooves 411, and one end of the connection tube 42 close to the other connection tube 42 has a sliding portion 421 adapted to the sliding groove 411. The connection tube 42 can slide relative to the tube body 41 along the axial direction of the tube body 41 through the cooperation between the sliding portion 421 and the sliding groove 411, and the connection tube 42 can rotate relative to the tube body 41 with the axis of the tube body 41 as the rotation axis. The inner cavity wall of the connection tube 42 is threaded except for the position where the sliding portion 421 is located. The connection tube 42 can be threadedly connected with the first connection end 13, the second connection end 22 and the third connection end 32. In order to facilitate the use of the connection tube 42, the outer surface of the connection tube 42 has anti-slip lines. In this embodiment, the accompanying drawings show the structure of the connection assembly 4 in the above-mentioned first pipe combination mode.

[0049] The connecting assembly 4 also includes two rotating members 43, which are respectively installed at the two ends of the tube body 41, and the rotating member 43 is connected to the tube body 41 by rotation with the axis of the tube body 41 as the axis, and the working principle of the rotating member 43 is similar to that of a bearing. The connecting assembly 4 also includes two abutting members 44 and two first elastic members 45, and the abutting members 44 and the elastic members correspond to the rotating member 43 one by one. The abutting member 44 is an annular structure, one end of the abutting member 44 is connected to the rotating member 43 in a sliding manner, and the sliding direction of the abutting member 44 is parallel to the axis of the tube body 41, and the other end of the abutting member 44 is located on the side of the rotating member 43 away from the tube body 41, and is used to abut against the end of the corresponding connecting end. The first elastic member 45 is installed inside the rotating member 43, and the first elastic member 45 drives the abutting member 44 to slide in the direction away from the tube body 41, so that after the connecting assembly 4 is installed, the abutting member 44 can be tightly pressed against the end of the corresponding connecting end. In this embodiment, it is preferred that the first elastic member 45 is a compression spring.

[0050] On the same connection assembly 4, after the two connection tubes 42 are threadedly connected with the corresponding connection ends, the positional relationship between adjacent pipes can be adjusted by controlling the two connection tubes 42 to rotate relative to the pipe body 41, thereby adapting to the specific installation environment.

[0051] After the connecting tube 42 is threadedly connected with the corresponding connecting end, the connecting tube 42 can drive the pipe fitting with which it is threadedly connected to rotate relative to the pipe body 41, and the pipe fittings on both sides of the pipe body 41 are controlled to rotate relative to the pipe body 41, so that the staff can adjust the relative position relationship between the pipe bodies 41 after the pipe fitting assembly is installed according to the installation environment or needs. In this embodiment, after the pipe fitting assembly is preferably installed, the water inlet end 11 of the first pipe fitting 1 and the insertion ends of other pipe fittings are in the same direction.

[0052] Reference Figure 4 and Figure 5After the connecting tube 42 is threadedly connected with the corresponding connecting end, the sliding portion 421 abuts against the groove wall of the sliding groove 411 at one end away from the other sliding groove 411, the first elastic member 45 is squeezed and deformed, and the abutting member 44 abuts against the end of the corresponding connecting end, so that the interior of the tube body 41 and the interior of the connecting tube 42 have good sealing properties; after the connecting tube 42 is threadedly connected with the corresponding connecting end, the connecting tube 42 slides until the sliding portion 421 abuts against the groove wall of the sliding groove 411 at one end close to the other sliding groove 411. At this time, the end of the connecting tube 42 away from the sliding portion 421 is located on the side of the adjacent connecting end close to the tube body 41, and the connecting assembly 4 can be directly removed.

[0053] During the process of the connecting tube 42 being threadedly connected to the corresponding connecting end, and during the process of the connecting tube 42 driving the pipe fitting to which it is threadedly connected to rotate relative to the pipe body 41, the rotating member 43 can rotate relative to the pipe body 41 under the action of the friction force generated by the abutment member 44 and the end of the connecting end, thereby reducing the probability of friction damage between the abutment member 44 and the end of the connecting end in the above two rotation situations.

[0054] Reference Figure 4 and Figure 6 The connecting assembly 4 further includes a plurality of cleaning members 46 and a plurality of second elastic members 47. The cleaning members 46 are respectively mounted at both ends of the tube body 41. The cleaning members 46 are slidably connected to the tube body 41. The sliding direction of the cleaning members 46 is perpendicular to the axis of the tube body 41. The cleaning members 46 mounted at the same end of the tube body 41 are distributed in a circular array with the axis of the tube body 41 as the axis. The sliding of the cleaning piece 46 relative to the tube body 41 is limited. When the cleaning piece 46 slides to the extreme position toward the direction close to the inside of the tube body 41, the end of the cleaning piece 46 close to the inside of the tube body 41 enters the space inside the tube body 41, and the end of the cleaning piece 46 away from the inside of the tube body 41 is flush with the bottom groove wall of the sliding groove 411; when the cleaning piece 46 slides to the extreme position toward the direction away from the inside of the tube body 41, the end of the cleaning piece 46 close to the inside of the tube body 41 is flush with the inner cavity wall of the tube body 41, and the end of the cleaning piece 46 away from the inside of the tube body 41 enters the space of the sliding groove 411.

[0055] The plurality of second elastic members 47 correspond to the plurality of cleaning members 46 one by one, and the second elastic members 47 are installed inside the tube body 41 itself, and the two ends of the second elastic member 47 are fixedly connected to the cleaning member 46 and the tube body 41 respectively, and the second elastic member 47 drives the cleaning member 46 to slide in a direction away from the inside of the tube body 41, so that the cleaning member 46 is kept at the limit position in a natural state. In this embodiment, the second elastic member 47 is preferably a compression spring.

[0056] Reference Figure 4 and Figure 7The connecting tube 42 is provided with a plurality of clearance grooves 422 on the end surface where the sliding portion 421 contacts the bottom groove wall of the sliding groove 411. The plurality of clearance grooves 422 are arranged in a circular array on the connecting tube 42 with the axis of the connecting tube 42 as the axis, and the spacing between adjacent clearance grooves 422 is twice the spacing between adjacent cleaning members 46. When the sliding portion 421 slides to abut against the groove wall of the sliding groove 411 away from another sliding groove 411, the sliding portion 421 can squeeze the plurality of cleaning members 46 in a natural state, so that the plurality of cleaning members 46 overcome the force of the second elastic member 47 and the ends of the plurality of cleaning members 46 enter the interior of the tube body 41.

[0057] The end of the cleaning piece 46 close to the inside of the tube body 41 also has an impact portion 461. When the connecting tube 42 and the tube body 41 rotate relatively, the cleaning piece 46 changes from the end penetrating into the inside of the tube body 41 to the end penetrating into the give way groove 422. After the second elastic piece 47 drives the cleaning piece 46 to slide, the impact portion 461 will collide with the tube body 41, causing the surrounding liquid to vibrate, so that the surrounding dirty substances attached to the inner wall of the tube body 41 can fall off, thereby achieving the cleaning function.

[0058] Reference Figure 3 In order to facilitate the staff to clean the pipe assembly in use, the pipe body 41 has a protrusion 412 between the two sliding grooves 411. The protrusion 412 is a structure that facilitates the staff to use tools or manually control its rotation relative to the connecting tube 42. In this embodiment, the structure of the protrusion 412 is preferably similar to that of the screw head, and the outer contour of the cross section is a regular hexagon.

[0059] Reference Figure 7 During the use of the pipe fitting combination, the ends of half of the cleaning pieces 46 on the same side of the pipe body 41 are kept inside the pipe body 41, and the ends of the other half of the cleaning pieces 46 are located in the clearance grooves 422. At this time, the dirt inside the pipe body 41 will be concentrated and attached to the inner wall of the pipe body 41 close to the position where the cleaning pieces 46 penetrate into the ends; when it is necessary to clean the pipe fitting combination, the pipe body 41 is controlled to rotate relative to the connecting tubes 42 on both sides thereof, so that the cleaning pieces 46 can slide back and forth regularly, generate vibrations to the liquid inside the pipe body 41, and cause the dirt attached to the inner wall of the pipe body 41 to fall off.

[0060] The implementation principle of a pipe assembly for draining condensed water from an air conditioner in the embodiment of the present application is as follows:

[0061] According to the number of drainage hoses, a suitable number of third pipe fittings 3 are selected, and the first pipe fitting 1, the second pipe fitting 2 and the third pipe fitting 3 are connected in pairs through the connecting assembly 4, so as to form a pipe fitting combination for multiple drainage hoses to discharge condensate. After the pipe fitting combination is installed, the multiple drainage hoses are inserted into the insertion ends of the pipe fittings one by one to complete the installation;

[0062] During the use of the connection assembly 4, the connection tube 42 is controlled to rotate relative to the tube body 41 so that the connection tube 42 can be threadedly connected with the connection end of the corresponding pipe fitting. After the connection tubes 42 on both sides of the pipe body 41 are connected with different pipe fittings, the connection tube 42 can be controlled to rotate relative to the pipe body 41 according to needs to adjust the positional relationship between two adjacent pipe fittings.

[0063] When removing a pipe on the pipe assembly, it is only necessary to control the connection tubes 42 on both sides of the pipe to release the threaded connection with the pipe, so that the pipe can be removed, which is convenient for disassembly and assembly of the pipe;

[0064] During the use of the pipe combination, by controlling the pipe body 41 to rotate relative to the connecting tubes 42 on both sides of itself, a number of clearing parts can be driven to slide regularly, thereby vibrating the liquid inside the pipe body 41, thereby detaching the dirt attached to the inner wall of the pipe body 41, making it easier for the dirt to be discharged along with the liquid.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
