[0001] This application relates to the technical field of air conditioners, and particularly to a pipe joint, a drainage assembly and an air conditioner. Background Art

[0002] When operating in the refrigeration mode or the humidification mode, since the surface temperature of the heat exchanger of the air conditioner is relatively low, the water vapor in the air near the heat exchanger condenses upon encountering cold, generating condensed water.

[0003] In the related art, a water tank for recovering condensed water is provided inside the air conditioner. The water tank is connected to the condensate pipe of the air conditioner to recover and reuse the condensed water of the air conditioner.

[0004] To avoid excessive water pressure in the water tank and damage to the water tank, a safety valve is usually installed on the water tank, and the overflow port of the safety valve is usually connected to a hose for discharging condensed water.

[0005] However, when the water pressure in the water tank exceeds the set pressure value of the safety valve, the condensed water ejected from the overflow port of the safety valve will drive the hose to swing, resulting in the splashing of the condensed water everywhere.

[0055] Next, embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0057] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0058] In the description of the embodiments of this application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can also be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific circumstances.

[0059] In the description of the embodiments of this application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order, or primary-secondary relationship of the indicated technical features. In the description of the embodiments of this application, the term "plurality" means two or more (including two). Similarly, "multiple groups" means two or more groups (including two groups), and "multiple pieces" means two or more pieces (including two pieces).

[0060] In the description of the embodiments of this application, the term "and / or" is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0061] In the related art, a water tank for recovering condensed water is provided inside an air conditioner. To avoid excessive water pressure in the water tank and damage to the water tank, a safety valve is usually installed on the water tank, and the overflow port of the safety valve is usually connected to a hose for discharging condensed water.

[0062] However, when the water pressure in the water tank exceeds the set pressure value of the safety valve, the condensed water ejected from the overflow port of the safety valve will drive the hose to swing, causing the condensed water to splash everywhere. The splashing condensed water will affect the normal operation of the internal equipment of the air conditioner.

[0063] To solve the above technical problems, the embodiments of the present application provide a pipe joint, a drainage assembly and an air conditioner, which can prevent the condensed water ejected from the safety valve of the air conditioner from splashing and ensure the normal operation of the internal equipment of the air conditioner.

[0064] The pipe joint, the drainage assembly and the air conditioner provided by the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings of the specification.

[0065] An air conditioner provided by an embodiment of the present application may be any one of a wall-mounted air conditioner indoor unit, a cabinet-type air conditioner indoor unit, an air machine, a ceiling-mounted air conditioner indoor unit, or a mobile air conditioner. The embodiments of the present application do not make specific limitations thereto.

[0066] The air conditioner includes a water tank, which is connected to the condensate pipe in the air conditioner and is used for centrally recycling and utilizing the condensed water, so as to avoid wasting water resources caused by directly discharging the condensed water outdoors. The recycled condensed water can be used to replenish water for the air conditioner and reduce the supplement of domestic water. For example, the condensed water recycled in the water tank can be used as the water source for humidifying the air conditioner. Moreover, by using the recycled condensed water as the water source for humidifying the air conditioner, users no longer need to add water to the air conditioner regularly, making the humidifying function of the air conditioner more intelligent and effectively improving the user experience.

[0067] To avoid damage to the water tank or other equipment in the air conditioner due to excessive water pressure in the water tank of the air conditioner, the air conditioner further includes a safety valve. The safety valve is usually installed on the top of the water tank. The safety valve has an overflow port. When the water pressure in the water tank exceeds the set pressure value of the safety valve, the condensed water is discharged from the overflow port of the safety valve, reducing the water pressure in the water tank. In this way, the water pressure in the water tank can be ensured to always remain within a safe range.

[0068] In addition, the air conditioner further includes a drainage assembly. Refer to Figure 1 and Figure 2 , the drainage assembly includes a pipe joint 200, a hose 300 and a drain pipe 400. The hose 300 is connected to the overflow port of the safety valve (not shown in the figure).

[0069] As Figure 3As shown in the figure, the pipe joint 200 includes a joint body 210 and a connection assembly 220. The joint body 210 includes a connected pipe body 211 and a first connection end 212; the connection assembly 220 includes a second connection end 221 and a connecting member 222, and the second connection end 221 is connected to one end of the pipe body 211 away from the first connection end 212 through the connecting member 222. One end of the hose 300 is connected to the second connection end 221, and the other end of the hose 300 is connected to the overflow port of the safety valve; one end of the drain pipe 400 is connected to the first connection end 212, and the other end of the drain pipe 400 is placed outside the housing of the air conditioner.

[0070] In this application, the second connection end 221 is connected to one end of the pipe body 211 away from the first connection end 212 through the connecting member 222, so that the second connection end 221 can be connected to the overflow port of the safety valve through the hose 300. When the condensed water ejected from the overflow port of the safety valve flows through the hose 300, it can enter the pipe body 211 and the first connection end 212 through the second connection end 221, and finally be discharged to the outside of the housing of the air conditioner through the drain pipe 400 connected to the first connection end 212. It can be seen that through this application, the condensed water ejected from the safety valve of the air conditioner can be prevented from splashing, ensuring the normal operation of the internal equipment of the air conditioner.

[0071] The first connection end 212 of the joint body 210 is connected to the drain pipe 400. It can be understood that in order to facilitate the installer to clearly know whether the first connection end 212 and the drain pipe 400 are installed in place, the diameter of the first connection end 212 can be set smaller than the diameter of the pipe body 211, such as Figure 2 As shown in the figure, a step is formed at the connection between the first connection end 212 and the pipe body 211. In this way, when the installer sets the drain pipe 400 on this step, it can be known that the first connection end 212 has been installed in place with the drain pipe 400.

[0072] In addition, in order to improve the connection tightness between the first connection end 212 and the drain pipe 400, in some embodiments, at least one convex portion 2121 surrounding the axis of the first connection end 212 can be provided on the outer periphery of the first connection end 212. Exemplarily, two convex portions 2121 can be provided at intervals as Figure 3 shown in the figure. Of course, four, five or more convex portions 2121 can also be provided according to actual situations. The interval distance between the convex portions 2121 can be flexibly set according to factors such as the length of the first connection end 212. By providing the convex portions 2121, when the first connection end 212 is connected to the drain pipe 400, the convex portions 2121 can expand and tighten the inner wall of the drain pipe 400, making the connection between the first connection end 212 and the drain pipe 400 tighter.

[0073] Inside an air conditioner, a water receiving tray 100 is usually installed. For example, the water receiving tray 100 is installed below the water tank of the air conditioner to receive the condensed water that the water tank fails to completely collect and the condensed water generated by the water tank itself. Refer to Figure 1 and Figure 3 , the water receiving tray 100 can be connected to the pipe body 211 of the joint body 210. Exemplarily, the water receiving tray 100 can be provided with a drain hole (not shown in the figure), and the pipe joint 200 is inserted through the drain hole.

[0074] In order to smoothly drain the condensed water in the water receiving tray 100, in some embodiments, the connecting member 222 can be provided with a notch 223 that exposes a part of the pipe body 211, and the notch 223 is used to guide the water in the water receiving tray 100 into the pipe body 211. Among them, the structural form of the connecting member 222 can be various. For example, a plate structure, a frame structure, etc. can be adopted.

[0075] When the connecting member 222 adopts a plate structure, refer to Figure 3 , Figure 4 and Figure 5 , in some embodiments, the connecting member 222 can include a main body portion 2220 and a plurality of connecting portions 2222: the main body portion 2220 has an installation hole 2221, and the main body portion 2220 is sleeved on the outer periphery of the second connection end 221 through the installation hole 2221; the plurality of connecting portions 2222 are arranged at intervals around the axis of the installation hole 2221 on the outer edge of the main body portion 2220; the notch 223 that exposes a part of the pipe body 211 is formed between adjacent connecting portions 2222; one end of the connecting portion 2222 is connected to the main body portion 2220, and the other end of the connecting portion 2222 is connected to the pipe body 211.

[0076] The main body portion 2220 serves as the installation basis for the connecting portions 2222. The installation hole 2221 formed inside it is used for installing the second connection end 221 on one hand, and for the condensed water in the second connection end 221 to pass through and enter the pipe body 211 on the other hand. The aperture size of the installation hole 2221 matches the outer diameter of the second connection end 221, and the present application does not make specific limitations on this. The connecting portions 2222 are arranged on the outer edge of the main body portion 2220 and can be connected to the pipe body 211, thereby providing support for the second connection end 221.

[0077] Considering guiding the condensed water collected by the water receiving tray 100 into the pipe body 211, the connecting portions 2222 can be provided in multiple numbers, and a notch 223 is formed between adjacent connecting portions 2222. The notch 223 can expose a part of the pipe body 211, so that the condensed water on the water receiving tray 100 enters the pipe body 211 from this notch 223. The number of the plurality of connecting portions 2222 can be two, three, four, etc., and the number of the notches 223 corresponds to the number of the connecting portions 2222. For example, as Figure 3 and Figure 4As shown, when the number of the connecting parts 2222 is four, four notches 223 can be formed accordingly.

[0078] The main body 2220 and the connecting portion 2222 of the connecting member 222 may be detachably connected or may be Figure 5 The one-piece component shown. Exemplarily, when the main body 2220 and the connecting part 2222 are detachably connected, the main body 2220 and the connecting part 2222 can be spliced parts. For example, one of the main body 2220 and the connecting part 2222 can be provided with a protruding structure, and the other can be provided with a corresponding concave structure, and the detachable connection between the two can be achieved through the protruding structure and the concave structure. The main body 2220 and the connecting part 2222 of the one-piece component can be formed by stamping or integral injection molding, which has the advantages of simple production and low cost.

[0079] In some embodiments, the bottom of the water receiving tray 100 can be provided with a water collecting tank 110 by stamping, injection molding, etc., and the water collecting tank 110 can collect the condensed water dripping on the water receiving tray 100. The drainage hole is opened in the bottom wall of the water collecting tank 110; the end surface of the tube body 211 is not higher than the upper surface of the bottom wall of the tank. For example, the end surface of the tube body 211 can be set to be flush with the upper surface of the bottom wall of the tank. In this way, the condensed water collected in the water collecting tank 110 can flow smoothly into the tube body 211.

[0080] It should be noted that there may be multiple ways of connecting the connector 222 and the pipe joint 200. In one possible implementation, Figure 6 As shown, the connector 222 can be fixedly connected to the inside of the pipe joint 200 by means of clamping, bonding, expansion connection, etc. In another possible implementation, as Figure 4 As shown, the connecting piece 222 can also be fixedly connected to the end surface of the pipe joint 200 by means of clamping, bonding, welding, etc.

[0081] For the water receiving pan 100 provided with the water collecting tank 110, the connecting piece 222 can be extended along the radial direction of the pipe joint 200, so that part of the connecting piece 222 protrudes from the pipe body 211, and then the part of the connecting piece 222 protruding from the pipe body 211 is connected to the water collecting tank 110, wherein the connection method is not limited to bonding, welding, clamping, etc. In this way, the connecting piece 222 can be connected to the pipe body 211 while also being connected to the water receiving pan 100, so that the connection firmness of the connecting piece 222 can be further improved, and better support can be provided for the second connecting end 221.

[0082] In some embodiments, at least a part of the surface of the water receiving tray 100 can be an inclined surface that is inclined relative to the horizontal plane; the water collecting groove 110 is located at the lower position of the inclined surface of the water receiving tray 100. For example, for the convenience of processing, the entire surface of the water receiving tray 100 can be set as an inclined surface. In addition, the surface of the water receiving tray 100 can also be set as an inclined surface that inclines towards a plurality of uniformly distributed drainage holes. The angle between the inclined surface and the horizontal plane can be θ, where 5° ≤ θ ≤ 15°, for example, it can be 5°, 6°, 8°, 10°, 12°, 14°, etc.

[0083] The shape of the water receiving tray 100 can be circular, oval, polygonal, etc., and the polygon can be a quadrilateral, a triangle, etc. As Figure 1 shown, in some embodiments, the water receiving tray 100 can be rectangular, and the drainage hole is located at one of the corners of the water receiving tray 100. The rectangular water receiving tray 100 is easy to manufacture, and the drainage hole is also easier to locate. In this way, the installation of the water receiving tray 100 can be facilitated. In addition, a water retaining portion 120 extending upward can be provided at the edge of the water receiving tray 100. The water retaining portion 120 can prevent the condensed water from dripping from the edge of the water receiving tray 100 and better realize the collection of the condensed water. The extension length of the water retaining portion 120 can be flexibly set according to actual needs, and the embodiments of the present application do not make specific limitations on this.
