[0035] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0036] As described in the background section, in household appliances such as heat pump air conditioners, the appliance casing typically needs a drain outlet to allow condensate and other liquids inside the casing to drain to the outside. However, with a drain outlet on the casing, when the components inside are in operation, the noise generated by these components can easily propagate to the outside of the casing through the drain outlet. This results in poor sealing and sound insulation of the casing, leading to high noise levels when the appliance is in operation.

[0037] To address the aforementioned technical problems, this application provides a pipe structure for a household appliance and the appliance in general. When a connector for the pipe body is installed in the housing, the connector can be inserted into the installation opening, allowing the pipe body to connect the inner and outer sides of the housing. Liquids such as condensate inside the housing can flow through the pipe body to the outer side of the housing, thereby filling the installation opening through the connector and reducing the possibility of liquid flowing from the connector and the inner wall of the installation opening to the outer side of the housing.

[0038] The connector is fitted with a sealing cover, which can be used to seal the gap between the connector and the installation port, reducing the possibility of gaps between the connector and the housing, improving the sealing and sound insulation of the housing, and thus reducing the noise generated when the household appliance is in operation.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0041] Reference Figures 1-4 This application provides a piping structure for a household appliance, including a pipe and a sealing cover 240. The pipe may include a pipe body 300 and a connector 200, and the connector 200 may be disposed at one end of the pipe body 300.

[0042] The connector 200 can be inserted into the mounting port 110 provided on the appliance housing 100 to drain the liquid inside the appliance housing 100 to the outside of the appliance housing 100. This can provide a certain degree of sealing to the mounting port 110, thereby improving the sealing performance of the appliance housing 100 and reducing the possibility of noise generated by components located inside the appliance housing 100 during operation being transmitted to the outside of the appliance housing 100 through the mounting port 110.

[0043] The sealing cover 240 can be fitted onto the connector 200 to seal the gap between the connector 200 and the mounting port 110.

[0044] When the connector 200 is fixed to the appliance housing 100, the sealing cover 240 can contact the appliance housing 100, thereby reducing the gap between the connector 200 and the inner wall of the appliance housing 100, reducing the possibility of liquid flowing from between the connector 200 and the appliance housing 100 to the mounting port 110, and improving the sealing performance of the connection between the connector 200 and the appliance housing 100.

[0045] The cross-sectional area of ​​the first end of the sealing cover 240 can be smaller than the cross-sectional area of ​​the second end of the sealing cover 240. The first end of the sealing cover 240 can be the end connected to the connector 200, and the second end of the sealing cover 240 can be the end connected to the household appliance housing 100.

[0046] By gradually changing the cross-sectional area, the sealing cover 240 can be formed into a flared structure. The first end tightly hugs the connector 200, and the second end expands and tightly presses against the mounting opening 110 of the household appliance housing 100, avoiding gaps. The larger contact area at the second end disperses the sealing pressure, preventing leakage caused by local deformation of the sealing cover 240.

[0047] The sealing cover 240 may have a certain height along the extension direction of the connector 200. The extension direction of the connector 200 may refer to its radial length. Having a certain height in this direction allows the sealing cover 240 to form a long-stroke seal, maintaining a seal even with minor misalignment or vibration of the connector 200 or the appliance housing 100. The sealing cover 240 covers a longer exposed portion of the connector 200, preventing the connector 200 from becoming loose due to external forces.

[0048] The first end of the sealing cover 240 may be provided with a stepped surface. The stepped surface can fit against the root of the joint 200 to form a preliminary sealing barrier.

[0049] Alternatively, the second end of the sealing cover 240 may be provided with a stepped surface. The stepped surface can be pressed against the edge of the mounting port 110 to distribute the sealing pressure.

[0050] Alternatively, the first and second ends of the sealing cover 240 are provided with stepped surfaces. The stepped surface at the first end can position the connector 200, and the stepped surface at the second end can fix the household appliance housing 100.

[0051] The sealing cover 240 can be rotatably connected to the connector 200. An annular guide rail can be provided on the inner wall of the sealing cover 240, and a corresponding protrusion or ball bearing structure can be provided on the outer surface of the connector 200, forming a dynamic sealing pair that can rotate relative to each other. The sealing cover 240 can rotate relative to the connector 200 to accommodate installation ports 110 in different directions, preventing the sealing cover 240 from twisting due to pipeline installation deviations and preventing localized pressure leakage.

[0052] The connector 200 can be rotatably connected to the pipe body 300. A bearing or rotating sleeve can be installed inside the connector 200 to engage with the groove or thread at the end of the pipe. The rotatable connection between the connector 200 and the pipe body 300 can prevent the pipe body 300 from being subjected to pressure and twisting, and can release the thermal stress of the pipeline structure through rotation.

[0053] The sealing cover 240 can be detachably connected to the appliance housing 100. For example, the sealing cover 240 can be threaded to engage with a threaded hole on the appliance housing 100, or the sealing cover 240 can be embedded with a magnet to attract the metal part of the appliance housing 100.

[0054] For example, the sealing cover 240 may be provided with a snap fastener 250 for engaging with the appliance housing 100. The edge of the sealing cover 240 may be provided with an elastic snap fastener 250, and the appliance housing 100 is provided with a corresponding fixing groove 130. Pressing the sealing cover 240 deforms the snap fastener 250, which snaps into the fixing groove 130 and then springs back to lock.

[0055] The buckle 250 can be located on the side of the sealing cover 240 near the appliance housing 100. When the connector 200 is fixed to the appliance housing 100, the second end of the sealing cover 240 is in contact with the appliance housing 100, and the buckle 250 located on the sealing cover 240 can be fixed to the appliance housing 100.

[0056] For example, along the direction perpendicular to the second end of the sealing cover 240, the orthographic projection of the buckle 250 in the plane containing the second end of the sealing cover 240 is located inside the sealing cover 240, so that the buckle 250 does not extend to the outside of the sealing cover 240, making the connection process between the buckle 250 and the fixing groove 130 more convenient.

[0057] It should be noted that the sealing cover 240 is arranged around the outside of the connector 200. By setting the orthographic projection of the buckle 250 in the plane where the second end of the sealing cover 240 is located on the inside of the sealing cover 240, the sealing cover 240 can fully contact the household appliance housing 100. The buckle 250 is located on the inside of the sealing cover 240, thereby reducing the possibility of liquid flowing from the plane where the second end of the sealing cover 240 is located and the fixing groove 130 to the mounting port 110.

[0058] By adopting the above technical solution, when the connector 200 is installed in the appliance housing 100, the connector 200 can be inserted into the installation port 110, so that the pipe body 300 can connect the inside and outside of the appliance housing 100. Liquids such as condensate inside the appliance housing 100 can flow to the outside of the appliance housing 100 through the pipe body 300, thereby filling the installation port 110 through the connector 200, reducing the possibility of liquid flowing from the connector 200 and the inner wall of the installation port 110 to the outside of the appliance housing 100.

[0059] Furthermore, the connector 200 can be fixed to the appliance housing 100 via the snap fastener 250, thus eliminating the need for the connector 200 to be fixed to the inner wall of the mounting opening 110. This allows the connection between the connector 200 and the appliance housing 100 to be located on the periphery of the mounting opening 110, reducing the possibility of gaps between the connector 200 and the appliance housing 100. This improves the sealing and sound insulation of the appliance housing 100, thereby reducing the noise generated when the appliance is in operation.

[0060] In some possible implementations, connector 200 may include a plug portion 220. The plug portion 220 may have a flow channel 210 and can be used to connect to a pipe body 300 located inside the appliance housing 100, so that liquid from the pipe body 300 can flow through the flow channel 210 of the plug portion 220 to the outside of the appliance housing 100.

[0061] For example, the pipe body 300 can be used to connect to the water circulation system 10 of the heat pump air conditioner. The drain pipe can be equipped with a safety valve 310. The safety valve 310 can be used to control the connection and closure of the pipe body 300, thereby reducing the possibility of excessive pressure or pipe rupture in the water circulation system 10.

[0062] The plug part 220 can be inserted into the outlet end of the pipe body 300, so that the plug part 220 can be inserted into the inside of the pipe body 300 and the drain pipe is sleeved on the outside of the pipe body 300, thereby realizing the plug-in cooperation between the plug part 220 and the pipe body 300, so that the liquid in the pipe body 300 can flow to the outside of the household appliance housing 100 through the guide channel 210 of the plug part 220.

[0063] The insertion part 220 can be interference-fitted with the inner wall of the pipe body 300, thereby reducing the gap between the insertion part 220 and the pipe body 300, reducing the possibility of liquid in the pipe body 300 flowing out from between the insertion part 220 and the pipe body 300, and improving the sealing between the pipe body 300 and the joint 200.

[0064] The connector 200 may include an abutment portion 230. The abutment portion 230 is connected to the insertion portion 220, and when the insertion portion 220 is connected to the pipe body 300, the abutment portion 230 can abut against the end of the pipe body 300. The abutment portion 230 can be used to support and bear the end of the pipe body 300, making the connection between the pipe body 300 and the connector 200 more stable.

[0065] The abutment portion 230 may be provided with an abutment groove for supporting the end of the pipe body 300. When the insertion portion 220 is connected to the pipe body 300, the end of the pipe body 300 may be disposed in the abutment groove, and at least a portion of the abutment portion 230 may be located on the outside of the pipe body 300, so that the abutment portion 230 can cooperate with the insertion portion 220. The abutment portion 230 and the insertion portion 220 are respectively disposed on both sides (inner and outer sides) of the pipe body 300, thereby reducing the possibility of the end of the pipe body 300 disengaging from the connector 200.

[0066] For example, the sealing cover 240 can be used as the structural basis of the abutment portion 230, that is, the abutment portion 230 can be provided on the sealing cover 240, and the abutment portion 230 can be located at the first end of the sealing cover 240.

[0067] When the connector 200 is fixed to the appliance housing 100, the second end of the sealing cover 240 contacts the appliance housing 100. The second end of the sealing cover 240 can be connected to the pipe body 300 and other structures through the abutment part 230, so that the sealing cover 240 can be disposed between the pipe body 300 and the appliance housing 100. This allows the sealing cover 240 to separate the pipe body 300 and the installation port 110 of the appliance housing 100, thereby reducing the possibility of liquid in the pipe body 300 flowing from the outside of the connector 200 into the installation port 110.

[0068] Reference Figures 2-5 In some possible implementations, the sealing cover 240 may be provided with a positioning guide 241.

[0069] The positioning guide 241 is located on the side of the sealing cover 240 away from the buckle 250 and perpendicular to the second end of the sealing cover 240. The positioning guide 241 is correspondingly arranged with the buckle 250, so that the positioning guide 241 can play a certain role in indicating the position of the buckle 250, making the connection process between the buckle 250 and the fixing groove 130 more convenient.

[0070] For example, the positioning guide 241 can be configured as a recessed positioning guide 241. The recessed positioning guide 241 can be recessed relative to the surface of the sealing cover 240. The recessed positioning guide 241 can be used to place a finger, allowing the user to apply force to the connector 200 through the recessed positioning guide 241, thereby facilitating the rotation of the connector 200 relative to the mounting port 110.

[0071] The positioning guide 241 can be configured as a protruding positioning guide 241. The protruding positioning guide 241 can be provided protruding relative to the surface of the sealing cover 240. The height of the protruding positioning guide 241 can be less than or equal to the height of the abutment 230, so that the protruding positioning guide 241 will not affect the setting of the abutment 230. Furthermore, the protruding positioning guide 241 can be used to indicate the position of the buckle 250. The user can apply force to the connector 200 through the protruding positioning guide 241, thereby making the rotation process of the connector 200 relative to the mounting port 110 more convenient.

[0072] Reference Figures 3-5 This application provides a household appliance, including a household appliance housing 100 and a piping structure of the household appliance as described in any of the above embodiments. The household appliance housing 100 may be provided with a fixing groove 130 for engaging with a snap fastener 250.

[0073] The fixing groove 130 can be set on the periphery of the mounting opening 110. When the connector 200 is inserted into the mounting opening 110, the buckle 250 and the fixing groove 130 are located on the periphery of the mounting opening 110, and there is a distance between the buckle 250 and the fixing groove 130 and the mounting opening 110, so that the connector 200 can abut against the inner wall of the mounting opening 110, thereby reducing the possibility of interference between the buckle 250 and the connector 200, and making the connection between the buckle 250 and the fixing groove 130 more stable.

[0074] The fixing groove 130 can extend circumferentially along the mounting opening 110 and has a certain curvature. This can extend the contact arc length between the buckle 250 and the mounting groove, resisting rotational loosening caused by vibration.

[0075] For example, when the connector 200 is in the first state, the buckle 250 can be inserted into the fixing groove 130, and the connector 200 can be fixed to the household appliance housing 100, thereby realizing the installation process of the connector 200.

[0076] When the connector 200 is in the second state, the buckle 250 can disengage from the fixing groove 130, and the connector 200 can be rotatably positioned in the mounting port 110, thereby allowing the position of the connector 200 to be adjusted so that the connector 200 can be inserted into the mounting port 110 or pulled out from the mounting port 110.

[0077] By adopting the above technical solution, when it is necessary to install and fix the connector 200 to the household appliance housing 100, the connector 200 can be inserted into the installation port 110, so that the connector 200 is in the second state. The connector 200 can rotate relative to the installation port 110, thereby adjusting the position of the connector 200. The connector 200 can drive the buckle 250 to move closer to or away from the corresponding fixing groove 130.

[0078] Then, the connector 200 can be rotated so that the buckle 250 approaches the fixing groove 130 and connects with the fixing groove 130, thereby enabling the connector 200 to be connected to the household appliance housing 100 through the cooperating buckle 250 and fixing groove 130, so that the connector 200 can be in the first state to realize the installation process of the connector 200.

[0079] When it is necessary to disassemble the connector 200 from the mounting port 110, the buckle 250 can be disengaged from the corresponding fixing groove 130, so that the connector 200 can rotate within the mounting port 110, thereby allowing the connector 200 to switch from the first state to the second state. Then, the connector 200 can be pulled out from the mounting port 110 to realize the disassembly process of the connector 200 from the household appliance housing 100.

[0080] For example, the connector 200 may be provided with an extension 260, one end of which is away from the connector 200 and connected to the buckle 250, so that the buckle 250 can be fixed to the connector 200 through the extension 260, thereby increasing the distance between the buckle 250 and the connector 200.

[0081] The extension 260 can extend circumferentially along the connector 200. The first end of the extension 260 is connected to the connector 200, and the second end of the extension 260 is connected to the buckle 250. When the connector 200 rotates relative to the mounting port 110, the extension 260 and the buckle 250 rotate relative to the mounting port 110. The rotation paths of the extension 260 and the buckle 250 are the same or approximately the same, thereby reducing the possibility of mutual interference between the extension 260 and the buckle 250.

[0082] For example, the appliance housing 100 may be provided with a guide opening 120, and the extension 260 may be inserted into the guide opening 120, so that the buckle 250 and the extension 260 can pass through the guide opening 120 through the appliance housing 100, thereby allowing the buckle 250 to extend to the outside of the appliance housing 100 through the guide opening 120.

[0083] The fixing groove 130 and the guide opening 120 can be set at intervals so that the fixing groove 130 will not connect with the guide opening 120, so that the engagement of the buckle 250 inserted into the fixing groove 130 is more stable.

[0084] The fixing groove 130 and the guide opening 120 can be arranged around the circumference of the mounting opening 110. The guide opening 120 can be set on one side of the fixing groove 130. When the connector 200 rotates relative to the mounting opening 110, the extension 260 can be movably set in the guide opening 120, and the buckle 250 is close to or away from the fixing groove 130.

[0085] In other words, when it is necessary to install and fix the connector 200 to the appliance housing 100, the connector 200 can be inserted into the mounting port 110, and the buckle 250 and the extension 260 can be inserted into the guide port 120. The buckle 250 can extend to the outside of the appliance housing 100 through the guide port 120.

[0086] Then, the connector 200 can be rotated so that the buckle 250 and the extension 260 rotate relative to the appliance housing 100, so that the buckle 250 can disengage from the guide port 120 and pass through the fixing groove 130, so that the buckle 250 can be fixed in the fixing groove 130, thereby fixing the connector 200 to the appliance housing 100.

[0087] There are multiple buckles 250 and extensions 260. Multiple buckles 250 are evenly arranged around the circumference of the connector 200, and each buckle 250 is connected to the connector 200 through an extension 260.

[0088] There can be multiple guide ports 120. The guide ports 120 are provided in correspondence with the extension 260. The extension direction of the guide ports 120 is parallel to the circumferential direction of the mounting port 110.

[0089] In summary, when the connector 200 is installed in the appliance housing 100, the connector 200 can be inserted into the installation port 110, so that the pipe body 300 can connect the inside and outside of the appliance housing 100. Liquids such as condensate inside the appliance housing 100 can flow to the outside of the appliance housing 100 through the pipe body 300, thereby filling the installation port 110 through the connector 200, reducing the possibility of liquid flowing from the connector 200 and the inner wall of the installation port 110 to the outside of the appliance housing 100.
