Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a water outlet nozzle, a water outlet method and an air conditioner. Background Art

[0002] In order to drain the condensed water inside the air conditioner smoothly, a water receiving tray is generally provided inside the air conditioner, and a water outlet is provided on the water receiving tray. The water outlet extends from the inside of the air conditioner to the outside of the air conditioner and is connected to an external drainage pipe to drain the condensed water.

[0003] In existing air-conditioning products, the water outlet on the water receiving tray generally includes: a water outlet pipe, a thermal insulation sleeve and a rubber plug, wherein one end of the water outlet pipe is connected to the drain hole on the water receiving tray, and the other end is connected to the external drainage pipe, and is closed by a rubber plug when drainage is not required. The thermal insulation sleeve is sleeved on the outer periphery of the water outlet pipe to prevent condensation water from forming on the water outlet.

[0004] However, it is found that the water outlet of this structure has the following defects:

[0005] First, in order to facilitate the connection with the external drainage pipe, the water outlet is generally long and cannot be extended to adjust its length. In this way, the water outlet will extend too long from the fuselage, which will cause the overall size of the air conditioner to be too large, which is not conducive to saving space. Secondly, during the transportation of the whole machine, the water outlet is easy to collide with other objects, causing damage to the water outlet or injuring others. Thirdly, as a structure protruding from the fuselage, the water outlet is very likely to be used as a fulcrum by workers during the transportation of the whole machine, but the strength of the water outlet is limited, which is very likely to cause the water outlet to break.

[0006] Second, during the production process of the water outlet, the water outlet pipe needs to be assembled with the insulation sleeve and the rubber plug in sequence, which makes the production efficiency of the water outlet low;

[0007] Third, it is difficult for the insulation sleeve to completely cover and stably connect with the root of the outlet pipe, which may lead to inadequate insulation at the root of the outlet pipe and condensation.

[0008] Fourth, during long-term use, the water outlet may leak or the rubber plug may fall off due to aging or size changes of the rubber plug.

[0009] Fifth, the water outlet does not have a filtering function, and foreign matter in the water tray can easily enter the drainage pipe through the water outlet, causing the drainage pipe to be blocked, and clearing the blockage or repairing it is usually very difficult.

[0010] In order to solve the above problems, this application is proposed. Summary of the invention

[0011] The present invention provides a water outlet nozzle, a water outlet method and an air conditioner to solve the technical problems of the existing water outlet nozzle that the length cannot be adjusted, the space occupied is large, the water outlet nozzle is easy to be damaged, the production and assembly efficiency is low, the anti-condensation effect is poor, the water outlet nozzle is easy to leak and the drainage pipe is easy to be blocked.

[0012] In order to solve the above problems, the present invention discloses a water outlet, comprising a main pipe and an extension part:

[0013] The main pipe comprises an outer pipe and an inner pipe, the inner pipe is sleeved in the outer pipe along the axial direction, one end of the main pipe is connected to the water receiving tray, and the other end is connected to the extension part;

[0014] The extension part includes an extension tube and an end cover. A plurality of drainage holes are arranged on the extension tube. One end of the extension tube can be slidably inserted between the outer tube and the inner tube, and the other end is closed by the end cover. Sliding the extension tube can open or close the drainage holes.

[0015] First, the water outlet described in the present application has the advantages of adjustable length, small size of the air conditioner, small occupied space, and not easy to be damaged by providing a slidably connected main pipe and an extension part, so that the water outlet has the advantages of being easy to adjust in length, small in size of the air conditioner, small in occupied space, and not easy to be damaged; second, the water outlet described in the present application only includes two components, the main pipe and the extension part, and has the advantages of simple and fast production and assembly; third, the double-layer pipe wall structure of the main pipe in the water outlet can effectively block the heat transfer and prevent condensation from forming on the outer surface of the main pipe; fourth, the water outlet described in the present application does not use the existing rubber plug to seal it, thereby avoiding the problem of water outlet leakage or rubber plug falling off caused by aging of the rubber plug or change in the size of the rubber plug; fifth, the water outlet described in the present application can filter foreign matter in the water receiving tray through the drainage hole to prevent foreign matter in the water receiving tray from clogging the drainage pipe outside the air conditioner, resulting in frequent and difficult maintenance.

[0016] Furthermore, the inner tube and the outer tube are coaxially arranged.

[0017] The inner tube and the outer tube are coaxially arranged so that the extension part can slide between the inner tube and the outer tube and rotate relatively to each other. The connection between the inner tube and the outer tube and the extension tube is no longer restricted by direction or angle, and the use is more flexible.

[0018] Furthermore, a clamping portion is provided on the main pipe, and an anti-slip portion is provided on the extending portion. When the extending portion is slid out of the main pipe, the clamping portion can be clamped together with the anti-slip portion.

[0019] The provision of the clamping portion and the anti-dropping portion prevents the extension tube from falling off from the main tube during sliding, thereby making the connection between the extension tube and the main tube very stable.

[0020] Furthermore, the clamping portion is arranged at the water outlet end of the main pipe, and the anti-detachment portion is arranged at the water inlet end of the extension portion.

[0021] The clamping portion is arranged at the water outlet end of the main pipe, and the anti-detachment portion is arranged at the water inlet end of the extension portion, so that the maximum range of adjustment of the length of the water outlet nozzle can be achieved.

[0022] Further, the clamping portion is an annular protrusion arranged on the inner side of the outer tube, and correspondingly, the anti-detachment portion is an annular protrusion arranged on the outer side of the extension tube;

[0023] Alternatively, the clamping portion is an annular protrusion arranged on the outer side of the inner tube, and correspondingly, the anti-detachment portion is an annular protrusion arranged on the inner side of the extension tube.

[0024] The clamping part and the anti-detachment part are arranged as annular protrusions, which can improve the clamping strength of the clamping part and the anti-detachment part, and can also seal the connection between the inner tube, the outer tube and the extension tube.

[0025] Furthermore, the clamping portion includes a plurality of annular raised sealing rings arranged at intervals on the inner side of the water outlet end of the outer tube, and the anti-detachment portion is an annular raised sealing ring arranged on the outer side of the water inlet end of the extension tube.

[0026] The clamping part is provided with a structure of multiple annular sealing rings arranged at intervals, so that the extension part can be prevented from falling off in multiple ways. Even if the anti-falling part passes over the annular protrusion closest to the water inlet end of the main pipe due to excessive force, it can still be clamped with the second annular protrusion. In addition, the provision of multiple annular protrusions can also improve the sealing performance between the outer pipe and the extension pipe.

[0027] Furthermore, the clamping portion and the anti-detachment portion are respectively provided with guiding inclined surfaces, and the guiding inclined surfaces are arranged obliquely along the direction in which the extending portion is inserted into the main pipe.

[0028] Under the guiding effect of the guiding slope, the extension tube is easier to be inserted between the inner tube and the outer tube.

[0029] Furthermore, a side wall is provided on the end cover, and the side wall extends from the end cover to the side where the extension tube is located, and forms an annular groove on the periphery of the extension tube, and the outer tube can be inserted into the annular groove and sealedly connected to the annular groove.

[0030] An annular groove is formed at the end of the extension pipe through the side wall, and the water outlet end of the main pipe is sealed through the annular groove.

[0031] Furthermore, the drainage hole is arranged on the extension pipe along the circumference of the extension pipe, and the drainage hole is located at an end of the extension pipe away from the main pipe.

[0032] The drainage hole is arranged along the circumference of the extension pipe at one end of the extension pipe away from the main pipe. When draining water, only a small part of the extension pipe needs to be pulled out from the main pipe to expose the drainage hole, and the water outlet can achieve drainage without completely pulling the extension pipe out of the main pipe. Under the premise that the water outlet can drain water outward, the length of the water outlet can be adjusted in a wide range, making it more flexible to use.

[0033] Furthermore, a mounting portion is provided at the water inlet end of the main pipe, and the main pipe is mounted on the water receiving tray through the mounting portion.

[0034] The main pipe can be quickly and conveniently installed on the water receiving tray through the installation part.

[0035] Further, the mounting portion includes a vertical mounting portion, and the vertical mounting portion is a plate-like structure arranged perpendicularly to the axis of the outer tube;

[0036] After the main pipe is installed on the water receiving tray, the vertical installation part is fitted and fixed on the inner wall of one side of the water receiving tray, and the inner pipe and the outer pipe pass through the through hole on the water receiving tray.

[0037] The main pipe can be quickly assembled with the water receiving tray through the vertical mounting portion.

[0038] Furthermore, the mounting portion further comprises a horizontal mounting portion, and the horizontal mounting portion is arranged on one side of the vertical mounting portion;

[0039] After the main pipe is installed on the water receiving tray, the horizontal installation portion is fitted and fixed on the inner wall of the other side of the water receiving tray or the inner side of the bottom wall.

[0040] The main pipe is limited by two different surfaces on the water receiving tray, so that the main pipe can be prevented from rotating freely while the main pipe is assembled with the water receiving tray, thereby further improving the installation stability of the main pipe.

[0041] Furthermore, a partial area of ​​the outer tube protrudes outward to form an internal hollow cavity, and the cavity is connected to the annular cavity between the outer tube and the inner tube; an air hole is arranged on the cavity, and a sealing plug is arranged on the air hole, and the sealing plug can be inserted into or pulled out of the air hole to seal or open the cavity.

[0042] When the sealing plug is inserted into the air hole, under the action of the atmospheric pressure inside the cavity and outside, the water outlet is in a "locked" state, and the extension tube cannot slide between the outer tube and the inner tube; in addition, the sealing plug can also be pulled out of the air hole. At this time, the atmospheric pressure inside the cavity and outside is connected, the water outlet is in an "unlocked" state, and the extension tube can slide between the outer tube and the inner tube to open or close the water outlet.

[0043] A water outlet method, the water outlet method uses the above-mentioned water outlet nozzle to discharge water outward, the water outlet method comprises:

[0044] S1, slide the extension tube between the outer tube and the inner tube;

[0045] S2, when the drain hole is clamped between the outer tube and the inner tube, the drain hole is closed and the water outlet is in a closed state;

[0046] S3, when the drainage hole slides out from between the outer tube and the inner tube, the drainage hole is opened and the water outlet is in an open state.

[0047] The drainage hole can be opened or closed by sliding, thereby realizing quick switching between the closed and open states of the water outlet, so that the water outlet can not only realize the telescopic adjustment of the size, but also quickly switch the open and closed states of the water outlet.

[0048] Furthermore, the step S2 includes the sub-steps of:

[0049] S21, sliding the extension pipe until the drainage hole is clamped between the outer pipe and the inner pipe, and the outer pipe is inserted into the annular groove, and the main pipe and the extension part are sealed and connected;

[0050] S22, inserting the sealing plug into the air hole, the water outlet is locked in a closed state.

[0051] When the extension tube is fully inserted between the outer tube and the inner tube, the water outlet end of the main tube is sealed by the end cover, the drainage hole is sealed by the outer tube and the inner tube, and the sealing plug is inserted into the air hole to achieve the "locking" of the relative sliding between the extension tube and the main tube, so that when the water outlet is in a closed state, the extension tube and the main tube are not prone to relative sliding, and each contact part between the main tube and the extension part can achieve good sealing.

[0052] Furthermore, the step S3 includes the sub-steps of:

[0053] S31, pulling out the sealing plug from the air hole to connect the cavity with the external atmosphere;

[0054] S32, pulling the extension tube out from between the inner tube and the outer tube, so that the drainage hole slides out from between the outer tube and the inner tube;

[0055] S33, when the extended tube is pulled out to a size that meets the requirement or the clamping portion and the anti-detachment portion are clamped together, stop pulling out the extended tube;

[0056] S34, inserting a sealing plug into the air hole on the cavity, so that the cavity is sealed;

[0057] S35, the water outlet is locked in an open state, and the condensed water in the water receiving tray first flows into the extension pipe through the main pipe, and then is discharged through the drainage hole.

[0058] The extension pipe can be stabilized and fixed at a certain designated position in the main pipe by the clamping part and the anti-detachment part or by the sealing plug, so that the total length of the water outlet can be adjusted as needed and the drainage hole can continuously drain water outward.

[0059] An air conditioner comprises the water outlet nozzle mentioned above.

[0060] In summary, the water outlet nozzle, water outlet method and air conditioner described in this application have the following advantages:

[0061] First, by providing a slidably connected main pipe and extension part, the length of the water outlet of the present application is adjustable, the size of the air conditioner is small, the space occupied is small, and the water outlet is not easily damaged;

[0062] Second, it only includes two parts, the main pipe and the extension part, which has the advantages of simple and fast production and assembly;

[0063] Third, the double-layer tube wall structure of the main pipe in the water outlet can effectively block the heat transfer and prevent condensation from forming on the outer surface of the main pipe;

[0064] Fourthly, the water outlet of the present application is not sealed with an existing rubber plug, thereby avoiding the problem of water outlet leakage or rubber plug falling off caused by aging of the rubber plug or change in the size of the rubber plug;

[0065] Fifth, the water outlet of the present application can filter foreign matter in the water receiving tray through the drainage hole to prevent the foreign matter in the water receiving tray from clogging the drainage pipe outside the air conditioner, resulting in frequent and difficult maintenance.

[0066] Sixth, the water outlet nozzle, water outlet method and air conditioner described in the present application also realize the "locking" and "unlocking" of the extension tube sliding between the inner tube and the outer tube through the setting of the cavity and the sealing plug, so that the extension tube can not only slide between the inner tube and the outer tube, but also can stably stay in a specific position between the inner tube and the outer tube, making it more flexible and convenient to use.

DETAILED DESCRIPTION

[0079] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0080] Example 1

[0081] like Figures 1 to 9 As shown, a water outlet includes a main pipe 1 and an extension part 2:

[0082] The main pipe 1 comprises an outer pipe 12 and an inner pipe 11, wherein the inner pipe 11 is axially sleeved inside the outer pipe 12, thereby forming an annular cavity between the outer pipe 12 and the inner pipe 11; one end of the main pipe 1 is connected to the water receiving tray 4, and the other end is connected to the extension pipe 21;

[0083] The extension portion 2 includes an extension tube 21 and an end cap 22 that closes one end of the extension tube 21, and a plurality of drainage holes 25 are provided on the extension tube 21; one end of the extension tube 21 can be slidably inserted between the outer tube 12 and the inner tube 11, and the other end is closed by the end cap 22 and exposed outside the outer shell 3 of the air conditioner, and the drainage holes 25 can be opened or closed by sliding the extension tube 21.

[0084] Preferably, the inner tube 11 and the outer tube 12 are coaxially arranged.

[0085] As the extension tube 21 slides between the outer tube 12 and the inner tube 11, when the extension tube 21 is inserted into the annular cavity between the outer tube 12 and the inner tube 11, and the drainage hole 25 is clamped between the outer tube 12 and the inner tube 11, the drainage hole 25 is sealed, and the water outlet cannot drain water outward; when the extension tube 21 is pulled out of the annular cavity between the outer tube 12 and the inner tube 11, and the drainage hole 25 slides out from between the outer tube 12 and the inner tube 11, the drainage hole 25 is opened, and the water outlet can drain water outward.

[0086] The water outlet described in the present application is provided with a main pipe 1 with a double-layer pipe wall and an extension part 2 that can be slidably inserted between the outer pipe 12 and the inner pipe 11, so that the length of the water outlet described in the present application can be adjusted by the extension and contraction of the extension part 2 in the main pipe 1. During the period when drainage is not performed, such as during assembly and transportation, the extension part 2 can be inserted into the main pipe 1, which greatly reduces the overall length of the water outlet and achieves the purpose of saving the overall size and occupied space of the air conditioner; in addition, it can also prevent the water outlet from being damaged or injuring others by being hit during transportation; furthermore, after the extension part 2 is inserted into the main pipe 1, the length of the water outlet is greatly reduced, and it is no longer convenient to serve as a fulcrum for transporting the air conditioner, which can effectively prevent the water outlet from breaking due to transportation.

[0087] The structure of the sliding and telescopic connection between the main pipe 1 and the extension part 2 in the water outlet makes the water outlet of the present application include only two parts, the main pipe 1 and the extension part 2. During production, only the main pipe 1 and the extension part 2 need to be manufactured separately. Later, during assembly, the extension part 2 can be inserted between the two layers of the pipe wall of the main pipe 1. The production and assembly are simple and fast, and the production efficiency can be greatly improved compared with the existing water outlets.

[0088] The double-wall structure of the main pipe 1 in the water outlet nozzle can form an annular cavity between the outer pipe 12 and the inner pipe 11, effectively blocking heat propagation and preventing condensation from forming on the outer surface of the main pipe 1 when the water outlet nozzle is in use.

[0089] The water outlet described in the present application is not sealed with an existing rubber plug, but is sealed with an end cover 22 integrally formed with the extension tube 21, thereby avoiding leakage of the water outlet or falling off of the rubber plug due to aging of the rubber plug or change in size of the rubber plug.

[0090] The water outlet of the present application can filter foreign matter in the water receiving tray 4 through the drainage hole 25 to prevent the foreign matter in the water receiving tray 4 from clogging the drainage pipeline outside the air conditioner, resulting in frequent and difficult maintenance.

[0091] Furthermore, a clamping portion 16 is provided on the main pipe 1, and an anti-detachment portion 26 is provided on the extension portion 2. When the extension portion 2 is slid out of the main pipe 1, the clamping portion 16 can be clamped together with the anti-detachment portion 26 to prevent the extension portion 2 from detaching from the main pipe 1, and the two are completely separated.

[0092] Furthermore, the clamping portion 16 is a protrusion or a groove arranged on the inner tube 11 and / or the outer tube 12, and correspondingly, the anti-detachment portion 26 is a protrusion or a groove arranged on the extension portion 2, wherein at least one of the clamping portion 16 and the anti-detachment portion 26 should be a protrusion.

[0093] In the present application, the condensed water in the water receiving tray 4 flows in from one end of the main pipe 1 and flows out from the other end, then flows in from one end of the extension part 2 and flows out from the drainage hole 25. In order to clearly explain the structure of each part of the water outlet of the present application, in the present application, the end of the main pipe 1 into which the condensed water flows is called the water inlet end of the main pipe 1, and the end into which the condensed water flows out is called the water outlet end of the main pipe 1; at the same time, the end of the extension part 2 into which the condensed water flows is called the water inlet end of the extension part 2. Then, the end of the main pipe 1 connected to the water receiving tray 4 is its water inlet end, and the end connected to the extension part 2 is its water outlet end; the end of the extension part 2 connected to the main pipe 1 is its water inlet end.

[0094] Preferably, the clamping portion 16 is arranged at the water outlet end of the main pipe 1, and the anti-detachment portion 26 is arranged at the water inlet end of the extension portion 2, so that the length of the water outlet nozzle can be adjusted to the greatest extent.

[0095] As some embodiments of the present application, the clamping portion 16 is a protrusion arranged on the inner side of the outer tube 12, and correspondingly, the anti-detachment portion 26 is a protrusion arranged on the outer side of the extension tube 21. In this way, when the extension portion 2 is pulled out from the main tube 1, the clamping portion 16 will be able to be clamped together with the anti-detachment portion 26 to prevent the extension portion 2 from detaching from the main tube 1.

[0096] As some embodiments of the present application, the clamping portion 16 is a protrusion arranged on the inner side of the outer tube 12, and correspondingly, the anti-detachment portion 26 is a groove arranged on the extension tube 21. In this way, when the extension portion 2 is pulled out from the main tube 1, the clamping portion 16 will be able to be inserted into the anti-detachment portion 26 and be clamped together with the anti-detachment portion 26 to prevent the extension portion 2 from detaching from the main tube 1.

[0097] Preferably, the clamping portion 16 is an annular protrusion arranged on the inner side of the water outlet end of the outer tube 12, and correspondingly, the anti-detachment portion 26 is an annular protrusion arranged on the outer side of the water inlet end of the extension tube 21. In this way, on the one hand, the clamping strength of the clamping portion 16 and the anti-detachment portion 26 can be improved, and at the same time, a sealing effect can be played on the connection between the inner tube 11, the outer tube 12 and the extension tube 21.

[0098] More preferably, the clamping portion 16 includes a plurality of annular protrusion-shaped sealing rings arranged at intervals on the inner side of the water outlet end of the outer tube 12, and correspondingly, the anti-detachment portion 26 is an annular protrusion-shaped sealing ring arranged on the outer side of the water inlet end of the extension tube 21. In this way, multiple anti-detachment of the extension portion 2 can be achieved, and even if the anti-detachment portion 26 passes over the annular protrusion closest to the water inlet end of the main tube 1 due to excessive force, it can still be clamped with the second annular protrusion. In addition, the provision of multiple annular protrusions can also improve the sealing between the outer tube 12 and the extension tube 21.

[0099] Furthermore, a chamfer is provided on the clamping portion 16, so that the side surface of the clamping portion 16 close to the water outlet end of the main pipe 1 is inclined from the outer pipe 12 to the side close to the water inlet end of the main pipe 1 to form a guiding slope; at the same time, a chamfer is also provided on the anti-detachment portion 26, so that the side surface of the anti-detachment portion 26 close to the water inlet end of the extension portion 2 is inclined from the extension pipe 21 to the side away from the water inlet end of the extension portion 2 to form a guiding slope, so that a guiding slope inclined along the direction of the extension portion 2 being inserted into the main pipe 1 is formed between the clamping portion 16 and the anti-detachment portion 26, and under the guiding action of the guiding slope, the extension pipe 21 is easier to insert between the inner pipe 11 and the outer pipe 12.

[0100] Furthermore, the clamping portion 16 can be made of the same material as the inner tube 11 or the outer tube 12, and prepared by integral molding with the main tube 1; it can also be made of a material different from the inner tube 11 or the outer tube 12, and be prepared separately from the inner tube 11 or the outer tube 12 and then installed on the inner tube 11 or the outer tube 12.

[0101] As some embodiments of the present application, the clamping portion 16 is made of the same material as the inner tube 11 or the outer tube 12 , such as plastic, and is integrally formed with the main tube 1 .

[0102] As some embodiments of the present application, the clamping portion 16 is made of a material different from that of the inner tube 11 or the outer tube 12. For example, the clamping portion 16 is made of a soft material such as rubber, and the inner tube 11 or the outer tube 12 is made of hard plastic, metal material, etc., and then the clamping portion 16 is installed on the inner tube 11 or the outer tube 12.

[0103] Preferably, the clamping portion 16 and the main pipe 1 are manufactured by integral molding; the anti-detachment portion 26 and the extending portion 2 are manufactured by integral molding.

[0104] Furthermore, a side wall 23 is provided on the end cover 22, and the side wall 23 extends from the end cover 22 to the side where the extension tube 21 is located, and finally cooperates with the extension tube 21 to form an annular groove 24 on the periphery of the extension tube 21. When the extension portion 2 is inserted into the main tube 1, the water outlet end of the outer tube 12 can be inserted into the annular groove 24 and connected with the annular groove 24 by an interference fit, thereby achieving sealing of the water outlet end of the main tube 1.

[0105] Furthermore, the drainage hole 25 is arranged at an end of the extension tube 21 away from the main tube 1, and the side wall 23 does not cover the drainage hole 25. In this way, the drainage hole 25 can be exposed by only pulling out a small part of the extension tube 21 from the main tube 1, and the water outlet can achieve drainage without pulling out the entire extension tube 21 from the main tube 1. This allows the water outlet to achieve outward drainage and the length of the water outlet can be adjusted, making it more flexible to use.

[0106] Preferably, the drainage holes 25 are arranged on the side wall of the extension tube 21 along the circumference of the extension tube 21 .

[0107] As some embodiments of the present application, the total opening area of ​​the drainage holes 25 is preferably sufficient to accommodate the maximum condensate flow rate of the air conditioner; the opening area of ​​a single drainage hole 25 is preferably sufficient to effectively filter foreign matter in the water receiving tray 4.

[0108] As some embodiments of the present application, a filter net is arranged on the drain hole 25, so that foreign matter in the condensed water can be filtered through the filter net, the opening area of ​​a single drain hole 25 can be set larger, and the total number of the drain holes 25 can be reduced to 2 to 8.

[0109] Furthermore, a mounting portion is provided at the water inlet end of the main pipe 1 , and the main pipe 1 is mounted on the water receiving tray 4 through the mounting portion.

[0110] Specifically, the mounting portion includes a vertical mounting portion 17, which is a plate-like structure arranged perpendicularly to the axis of the inner tube 11 and the outer tube 12. During installation, the vertical mounting portion 17 of the main tube 1 is fitted and fixed on the inner wall of one side of the water receiving tray 4, and the inner tube 11 and the outer tube 12 are exposed outside the outer shell 3 of the air conditioner after passing through the through hole on the water receiving tray 4. In this way, the main tube 1 can be assembled with the water receiving tray 4 through the vertical mounting portion 17.

[0111] Furthermore, the mounting portion also includes a horizontal mounting portion 18, and the horizontal mounting portion 18 is arranged on one side of the vertical mounting portion 17. During installation, the vertical mounting portion 17 is fitted and fixed on the inner wall of one side of the water receiving tray 4, and the horizontal mounting portion 18 is fitted and fixed on the inner wall of the other side of the water receiving tray 4 or the inner side of the bottom wall. In this way, the main pipe 1 is limited by two different surfaces on the water receiving tray 4. While the main pipe 1 is assembled with the water receiving tray 4, the rotation of the main pipe 1 can be avoided, thereby further improving the installation stability of the main pipe 1.

[0112] Furthermore, a reinforcing rib 19 is provided at the connection between the vertical mounting portion 17 and the outer tube 12. The provision of the reinforcing rib 19 can improve the connection strength between the vertical mounting portion 17 and the outer tube 12, thereby improving the strength of the water outlet.

[0113] Preferably, a plurality of reinforcing ribs 19 are arranged at intervals along the circumference of the outer tube 12 .

[0114] Further, such as Figures 4 to 9 As shown, a portion of the outer tube 12 protrudes outward to form an internally hollow cavity 13 , and the cavity 13 is communicated with the annular cavity between the outer tube 12 and the inner tube 11 .

[0115] Furthermore, an air hole is arranged on the mold cavity 13, and a sealing plug 14 is arranged on the air hole, and the sealing plug 14 can be inserted into the air hole, so that the mold cavity 13 and the annular cavity between the outer tube 12 and the inner tube 11 are all sealed; at this time, due to the action of the internal and external pressures of the mold cavity 13, the water spout is in a "locked" state, and the extension tube 21 cannot slide between the outer tube 12 and the inner tube 11; the sealing plug 14 can also be pulled out from the air hole, so that the mold cavity 13, the annular cavity between the outer tube 12 and the inner tube 11 are all connected to the external atmosphere; at this time, the water spout is in an "unlocked" state, and the extension tube 21 can slide between the outer tube 12 and the inner tube 11 to open or close the water spout.

[0116] Preferably, the sealing plug 14 is connected to the water outlet through a connecting portion 15 to prevent the sealing plug 14 from being accidentally dropped or lost after being pulled out of the air hole.

[0117] In addition, the present application also provides a water outlet method, wherein the water outlet method uses the above-mentioned water outlet nozzle to discharge water outwardly, and the water outlet method comprises:

[0118] S1, sliding the extension tube 21 between the outer tube 12 and the inner tube 11;

[0119] S2, when the drainage hole 25 is clamped between the outer tube 12 and the inner tube 11, the drainage hole 25 is closed and the water outlet is in a closed state;

[0120] S3, when the drainage hole 25 slides out from between the outer tube 12 and the inner tube 11, the drainage hole 25 is opened, and the water outlet can drain water outward.

[0121] Furthermore, the step S2 includes the sub-steps of:

[0122] S21, sliding the extension tube 21 until the drainage hole 25 is clamped between the outer tube 12 and the inner tube 11, and the outer tube 12 is inserted into the annular groove 24, and the main tube 1 and the extension part 2 are sealed and connected;

[0123] S22, insert the sealing plug 14 into the air hole, and lock the water outlet in a closed state.

[0124] Specifically, when the air conditioner does not need to drain, such as during assembly or transportation, the water outlet is in a closed state. Figure 4 and 6 As shown, first, the extension tube 21 is inserted between the inner tube 11 and the outer tube 12, and the inner tube 11 and the extension tube 21 are sealed and connected by interference fit, and the outer tube 12 and the extension tube 21 are connected by interference fit through the clamping portion 16 and the anti-detachment portion 26; at the same time, the water outlet end of the main pipe 1 is inserted into the annular groove 24, and the water outlet end of the main pipe 1 is sealed by interference fit; then the sealing plug 14 is inserted into the air hole on the cavity 13 to seal the air hole; in this way, the water outlet nozzle is in a sealed state as a whole, and due to the effect of the external atmospheric pressure, the end cover 22 and the sealing plug 14 are not easy to fall off, the extension tube 21 cannot slide out of the main pipe 1, the water outlet nozzle is in a stable and reliable closed state as a whole, and the length of the water outlet nozzle is in a contracted state, which is not easy to be damaged or injure others, and will not increase the overall size of the air conditioner too much.

[0125] Furthermore, the step S3 includes the sub-steps of:

[0126] S31, pulling out the sealing plug 14 from the air hole, so that the cavity 13 is connected to the external atmosphere;

[0127] S32, pulling the extension tube 21 out from between the inner tube 11 and the outer tube 12, so that the drainage hole 25 slides out from between the outer tube 12 and the inner tube 11;

[0128] S33, when the extended tube 21 is extended to a size that meets the requirement or the clamping portion 16 and the anti-detachment portion 26 are clamped together, stop pulling out the extended tube 21;

[0129] S34, inserting the sealing plug 14 into the air hole on the cavity 13, so that the cavity 13 is sealed;

[0130] S35 , the water outlet is locked in the open state, and the condensed water in the water receiving tray 4 first flows into the extension pipe 21 through the main pipe 1 , and then is discharged through the drainage hole 25 .

[0131] Specifically, when the air conditioner needs to drain water, such as in cooling or heating operation, the water outlet is in an open state: Fig. 9As shown, first, the sealing plug 14 is pulled out from the air hole on the cavity 13. At this time, the cavity 13, the annular cavity between the outer tube 12 and the inner tube 11 are connected to the external atmosphere, and the extension tube 21 can be pulled out from between the inner tube 11 and the outer tube 12 to expose the drainage hole 25 on the extension tube 21. When the size of the extension tube 21 pulled out meets the requirements or the clamping part 16 and the anti-detachment part 26 are clamped together, the extension tube 21 is stopped from being pulled out, and the sealing plug 14 is inserted into the air hole on the cavity 13 to seal the cavity 13, the annular cavity between the outer tube 12 and the inner tube 11 again, and the annular cavity between the outer tube 12 and the inner tube 11 will also be sealed by the clamping part 16 and the anti-detachment part 26 at the same time, so that the extension tube 21 is not easy to slide between the outer tube 12 and the inner tube 11 under the action of the external atmospheric pressure, and is in a "locked" state. At this time, the condensed water in the water receiving tray 4 can flow into the extension tube 21 through the main tube 1, and then be discharged through the drainage hole 25. Foreign matter in the water receiving tray 4 can be filtered through the drainage hole 25. When dirt and blockage occur, just pull out the extension part 2 from the main tube 1, clean it, and then insert it into the main tube 1 again. The main tube 1 forms a hollow annular cavity between the inner tube 11 and the outer tube 12 through the arrangement of the inner tube 11 and the outer tube 12, which can effectively hinder the spread of heat and prevent the generation of condensed water on the outer wall of the main tube 1.

[0132] Finally, the present application also provides an air conditioner having the above-mentioned water outlet nozzle.

[0133] In summary, the water outlet nozzle, water outlet method and air conditioner described in the present application: first, by providing a slidably connected main pipe 1 and an extension part 2, the length of the water outlet nozzle of the present application is adjustable, the size of the air conditioner is small, the space occupied is small, and the water outlet nozzle is not easy to be damaged; second, it only includes two components, the main pipe 1 and the extension part 2, and has the advantages of simple and fast production and assembly; third, the double-layer tube wall structure of the main pipe 1 in the water outlet nozzle can effectively block heat propagation and prevent condensation from forming on the outer surface of the main pipe 1; fourth, the water outlet nozzle of the present application is not sealed with an existing rubber plug, thereby avoiding the problem of water outlet leakage or rubber plug falling off caused by aging of the rubber plug or change in the size of the rubber plug; fifth, the water outlet nozzle of the present application can filter foreign matter in the water receiving tray 4 through the drainage hole 25 to prevent foreign matter in the water receiving tray 4 from clogging the drainage pipeline outside the air conditioner, resulting in frequent and difficult maintenance.

[0134] In addition, the water outlet nozzle, water outlet method and air conditioner described in the present application also realize the "locking" and "unlocking" of the extension tube 21 sliding between the inner tube 11 and the outer tube 12 through the setting of the cavity 13 and the sealing plug 14, so that the extension tube 21 can not only slide between the inner tube 11 and the outer tube 12, but also can stably stay in a specific position between the inner tube 11 and the outer tube 12, making it more flexible and convenient to use.
