Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a washing arm assembly. Background Technology

[0002] Dishwashers are common household appliances used to automatically clean dishes and plates. In traditional dishwashers, the wash arm assembly plays a crucial role. In current technology, the wash arm assembly typically consists of the wash arm and a water supply pipe. Because the wash arm needs to rotate relative to the water supply pipe, a gap exists at the connection between the wash arm and the water supply pipe, which leads to water leakage. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a washing arm assembly that reduces water leakage.

[0004] The present invention provides a wash arm assembly, including a wash arm and a water supply pipe for supplying water to the wash arm. The wash arm is rotatably connected to the water supply pipe. A leak-proof component is provided between the wash arm and the water supply pipe to prevent water leakage between the wash arm and the water supply pipe. The leak-proof component includes an inner annular flange that is tightly connected to the wash arm and abuts against the outer wall of the water supply pipe.

[0005] Furthermore, the washing arm includes a washing arm body and a connecting pipe fixed on the washing arm body. The washing arm body and the water supply pipe are connected through the connecting pipe, and the internal annular flange is disposed on the inner wall at the bottom of the connecting pipe.

[0006] Furthermore, a limiting flange is fitted onto the water supply pipe, and the bottom end of the connecting pipe abuts against the limiting flange.

[0007] Furthermore, the leak-proof component includes an upper annular flange disposed on the inner annular flange and protruding toward the water supply pipe, the upper annular flange abutting against the upper end of the water supply pipe and perpendicular to the inner annular flange.

[0008] Furthermore, the leak-proof component includes a lower annular flange disposed on the inner annular flange and protruding toward the connecting pipe, the lower annular flange being tightly connected to the lower end of the connecting pipe and perpendicular to the inner annular flange.

[0009] Furthermore, the leak-proof component includes an outer annular flange disposed on the lower annular flange and protruding toward the wash arm body, the outer annular flange being tightly connected to the outer wall of the connecting pipe and parallel to the inner annular flange.

[0010] Furthermore, the leak-proof component includes a connecting flange disposed on the outer annular flange and protruding away from the connecting pipe, the connecting flange being tightly connected to the wash arm body and perpendicular to the outer annular flange.

[0011] Furthermore, an annular sleeve is fitted on the outer wall of the water supply pipe, and the annular sleeve abuts against the inner annular flange.

[0012] Furthermore, the annular sleeve is provided with a top sleeve, which is tightly connected to the top end of the water supply pipe and is perpendicular to the annular sleeve.

[0013] Furthermore, the annular sleeve is provided with a bottom sleeve, which is tightly connected to the limiting flange and is perpendicular to the annular sleeve.

[0014] The above technical solution has the following beneficial effects:

[0015] The washing arm of this invention is rotatably connected to the water supply pipe, and there is a gap between the washing arm and the water supply pipe. When the washing arm rotates, water will leak at the connection between the washing arm and the water supply pipe. The presence of the internal annular flange increases the path length of water flow through the connection and shortens the distance of the gap between the washing arm and the water supply pipe, thereby reducing the possibility of leakage.

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0029] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meanings of the above within the context of this invention as appropriate.

[0031] In some embodiments of the present invention, a washing arm 1 and a water supply pipe 2 for supplying water to the washing arm 1 are included. The washing arm 1 is rotatably connected to the water supply pipe 2. A leak-proof component 3 is provided between the washing arm 1 and the water supply pipe 2 to prevent water leakage between the washing arm 1 and the water supply pipe 2. The leak-proof component 3 includes an inner annular flange 31 that is tightly connected to the inner wall of the bottom of the washing arm 1. The inner annular flange 31 abuts against the outer wall of the water supply pipe 2.

[0032] Specifically, in the wash arm 1 assembly, the inner annular flange 31 serves to prevent water leakage. The inner annular flange 31 is tightly connected to the bottom of the inner wall of the wash arm 1, while the outer wall of the water supply pipe 2 abuts against the inner annular flange 31. When assembling the wash arm 1 assembly, the water supply pipe 2 supplies water through a rotational connection with the wash arm 1. The wash arm 1 rotates relative to the water supply pipe 2, thereby changing the water flow direction and spray range. The inner annular flange 31 is located on the inner wall of the bottom of the washing arm 1 and is tightly fixed to the inner wall of the washing arm 1. When the washing arm 1 rotates, the inner annular flange 31 and the outer wall of the water supply pipe 2 form a tortuous channel, reducing the risk of water leakage at the connection. The presence of the inner annular flange 31 increases the path length of water flow through the connection and shortens the distance between the washing arm 1 and the water supply pipe 2, so that the water flow must pass through a series of tortuous channels to pass through the connection, thereby reducing the speed and pressure of water flow through the connection and reducing the possibility of leakage. The contact between the inner annular flange 31 and the outer wall of the water supply pipe 2 forms a tight seal to prevent water from overflowing from the connection.

[0033] In practical applications, the wash arm 1 assembly can be widely used in various occasions that require water flow control and leakage prevention, such as dishwashers, washing machines, and shower devices. By adopting the connection method of the bottom internal annular flange 31, the performance and reliability of the wash arm 1 assembly can be improved, and water leakage problems can be avoided.

[0034] Optionally, the inner annular flange 31 and the washing arm 1 can be detachably connected or fixedly connected.

[0035] In some embodiments of the present invention, the washing arm 1 includes a washing arm body 11 and a connecting pipe 12 fixed on the washing arm body 11. The washing arm body 11 and the water supply pipe 2 are connected through the connecting pipe 12. An internal annular flange 31 is provided on the inner wall of the bottom of the connecting pipe 12.

[0036] The wash arm 1 assembly includes a wash arm body 11, a connecting pipe 12, and an inner annular flange 31. The wash arm body 11 is the main part of the wash arm 1 assembly. The connecting pipe 12 is fixed on the wash arm body 11, and the wash arm body 11 and the water supply pipe 2 are connected through the connecting pipe 12. The inner annular flange 31 is provided on the inner wall of the bottom of the connecting pipe 12. When assembling the wash arm 1 assembly, the connecting pipe 12 is connected to the wash arm body 11 by being fixed on the wash arm body 11. The water supply pipe 2 is connected to the connecting pipe 12 and provides water to the wash arm 1 through the connecting pipe 12. The inner annular flange 31 is tightly connected to the inner wall of the bottom of the connecting pipe 12 and abuts against the outer wall of the water supply pipe 2. When water enters the connecting pipe 12 through the water supply pipe 2, the water flow will enter the washing arm body 11 through the connecting pipe 12, thereby realizing the water supply function. The washing arm 1 assembly achieves reliable water supply and leak prevention through the design of the connecting pipe 12 and the internal annular flange 31, improving the performance and reliability of the washing arm 1 assembly.

[0037] In some embodiments of the present invention, a limiting flange 21 is fitted on the water supply pipe 2, and the bottom end of the connecting pipe 12 abuts against the limiting flange 21.

[0038] Specifically, the limiting flange 21 is a protruding part fitted onto the water supply pipe 2. The bottom end of the connecting pipe 12 abuts against the limiting flange 21, forming a support platform on which the washing arm 1 can rotate. When assembling the washing arm 1 assembly, the bottom end of the connecting pipe 12 abuts against the top or edge of the limiting flange 21, so that the bottom of the connecting pipe 12 contacts or fits against the limiting flange 21. The limiting flange 21 provides a support platform for the washing arm 1 and ensures a stable connection between the connecting pipe 12 and the water supply pipe 2. The limiting flange 21 plays a role in fixing and supporting the washing arm 1. The washing arm 1 can rotate around the water supply pipe 2 on the limiting flange 21 to achieve water spraying in different directions and ranges.

[0039] In some embodiments of the present invention, the leak-proof component 3 includes an upper annular flange 32 disposed on the inner annular flange 31 and protruding toward the water supply pipe 2. The upper annular flange 32 abuts against the upper end of the water supply pipe 2 and is perpendicular to the inner annular flange 31.

[0040] Specifically, the leak-proof component 3 is a component used to prevent water leakage between the wash arm 1 and the water supply pipe 2. The leak-proof component 3 includes an upper annular flange 32 located at the upper end of the inner annular flange 31, protruding towards the water supply pipe 2. The upper annular flange 32 abuts against the upper end of the water supply pipe 2 and is perpendicular to the inner annular flange 31. The upper annular flange 32 covers and abuts against the upper end of the pipe wall of the water supply pipe 2. The upper annular flange 32 and the inner annular flange 31 are integrally formed to constitute the leak-proof component 3. The leak-proof component 3 serves to seal and prevent water leakage. By setting the upper annular flange 32, which abuts against the upper end of the water supply pipe 2 and is perpendicular to the inner annular flange 31, an additional sealing layer is formed, increasing the path length of water flow through the connection and shortening the distance of the gap between the wash arm 1 and the water supply pipe 2, effectively preventing water leakage.

[0041] In some embodiments of the present invention, the leak-proof component 3 includes a lower annular flange 33 disposed on the inner annular flange 31 and protruding toward the connecting pipe 12. The lower annular flange 33 is tightly connected to the lower end of the connecting pipe 12 and is perpendicular to the inner annular flange 31.

[0042] Specifically, the leak-proof component 3 is used to prevent water leakage between the washing arm 1 and the water supply pipe 2. The leak-proof component 3 includes a lower annular flange 33 located at the lower end of the inner annular flange 31 and protruding towards the connecting pipe 12. The lower annular flange 33 is tightly connected to the lower end of the connecting pipe 12 and is perpendicular to the inner annular flange 31. The leak-proof component 3 plays a role in sealing and preventing water leakage. By setting the lower annular flange 33, it is tightly connected to the lower end of the connecting pipe 12 and integrally formed with the inner annular flange 31 to form the leak-proof component 3. The lower annular flange 33 forms an additional sealing layer, which increases the path length of water flow through the connection and shortens the distance of the gap between the washing arm 1 and the water supply pipe 2, effectively preventing water leakage.

[0043] In some embodiments of the present invention, the leak-proof component 3 includes an outer annular flange 34 disposed on the lower annular flange 33 and protruding toward the wash arm body 11. The outer annular flange 34 is tightly connected to the outer wall of the connecting pipe 12 and is parallel to the inner annular flange 31.

[0044] Specifically, the leak-proof component 3 includes an outer annular flange 34 disposed on the lower annular flange 33 and protruding toward the wash arm body 11. The outer annular flange 34 is tightly connected to the outer wall of the connecting pipe 12 and is parallel to the inner annular flange 31. The outer annular flange 34, the lower annular flange 33, and the inner annular flange 31 are integrally formed to form a Z-shaped structure. The pipe wall of the connecting pipe 12 is disposed between the inner annular flange 31 and the outer annular flange 34.

[0045] When assembling the wash arm 1 assembly, the lower annular flange 33 is located at the bottom of the inner annular flange 31 and the outer annular flange 34, and is perpendicular to both the inner and outer annular flanges 31 and 34. The inner and outer annular flanges 31 and 34 are parallel. The outer annular flange 34 is integrally formed with the lower annular flange 33 and the inner annular flange 31, and is tightly connected to the pipe wall of the connecting pipe 12. The lower annular flange 33, the outer annular flange 34, and the inner annular flange 31 together form a Z-shaped structure, providing multiple sealing layers and effectively preventing water leakage.

[0046] Specifically, the connecting flange 35 is tightly connected to the wash arm body 11 and perpendicular to the outer annular flange 34. The connecting flange 35 is detachably connected to the wash arm body 11. All components of the leak-proof component 3 are integrally formed to form the leak-proof component 3. The leak-proof component 3 is connected to the wash arm 1 via the connecting flange 35, making it easy to disassemble, maintain, and clean. The connecting flange 35 serves to fix the leak-proof component 3. By being integrally formed with the outer annular flange 34, the connecting flange 35 can firmly fix the leak-proof component 3 to the wash arm 1, ensuring that the leak-proof component 3 will not loosen or fall off. The fixing effect of the connecting flange 35 helps maintain the positional stability of the leak-proof component 3. The connecting flange 35 and the outer annular flange 34 provide support and fixation, preventing the leak-proof component 3 from shifting or failing due to the movement of the wash arm 1.

[0047] In some embodiments of the present invention, an annular sleeve 4 is fitted on the outer wall of the water supply pipe 2, and the annular sleeve 4 abuts against the inner annular flange 31.

[0048] Specifically, the annular sleeve 4 is an annular structure, usually made of stainless steel, but can also be made of other wear-resistant materials. Its inner diameter is adapted to the outer diameter of the water supply pipe 2, and its length is sufficient to cover the inner annular flange 31.

[0049] The annular sleeve 4 is installed on the outer wall of the water supply pipe 2. Its inner diameter matches the outer diameter of the pipe. It fits tightly against the water supply pipe 2 and is generally fixedly connected, forming a seal with the pipe. When the washing arm 1 rotates during use, the connection point between the water supply pipe 2 and the washing arm 1 will experience a certain amount of friction and wear.

[0050] The annular sleeve 4, acting as a protective layer, is located on the outer wall of the water supply pipe 2, reducing direct friction and wear, and preventing excessive wear between the wash arm 1 and the water supply pipe 2. The inner annular flange 31, through its contact with the annular sleeve 4, enhances the sealing of the connection point, further preventing leakage. The annular sleeve 4 is fitted onto the outer wall of the water supply pipe 2, ensuring a tight fit. When installing the wash arm 1, the inner annular flange 31 contacts the annular sleeve 4, ensuring the stability and sealing of the connection point. The annular sleeve 4 provides protection for the water supply pipe 2, reduces friction and wear between the wash arm 1 and the pipe, and extends the service life of the wash arm 1 assembly.

[0051] In some embodiments of the present invention, the annular sleeve 4 is provided with a top sleeve 5, which is tightly connected to the top end of the water supply pipe 2 and is perpendicular to the annular sleeve 4.

[0052] Specifically, the length of the annular sleeve 4 is sufficient to cover the inner annular flange 31. The top sleeve 5 is a tubular structure attached to the top of the annular sleeve 4, its shape matching the top of the water supply pipe 2 and tightly connected to it. The top sleeve 5 is installed on top of the annular sleeve 4, perpendicular to the annular sleeve 4, and tightly connected to the top of the water supply pipe 2. By tightly connecting to the top of the water supply pipe 2, the top sleeve 5 forms a protective layer, preventing wear and damage to the top of the water supply pipe 2. The top sleeve 5 is vertically connected to the annular sleeve 4, located on top of the annular sleeve 4, and integrally formed with the annular sleeve 4. The top sleeve 5 provides protection for the top of the water supply pipe 2, reducing friction and wear between the wash arm 1 and the pipe, and extending the service life of the wash arm 1 assembly. The connection between the annular sleeve 4 and the top sleeve 5 can also be achieved by various methods, such as adhesive, threaded connection, or other suitable connection methods.

[0053] In some embodiments of the present invention, the annular sleeve 4 is provided with a bottom sleeve 6, the bottom sleeve 6 is tightly connected to the limiting flange 21, and the bottom sleeve 6 is perpendicular to the annular sleeve 4.

[0054] Specifically, the bottom sleeve 6 is a tubular structure attached to the bottom of the annular sleeve 4. Its shape matches and is tightly connected to the limiting flange 21. The bottom sleeve 6 is installed at the bottom of the annular sleeve 4, tightly connected to the limiting flange 21, and perpendicular to the annular sleeve 4. When the washing arm 1 rotates during use, the connection point between the washing arm 1 and the limiting flange 21 may experience some friction and wear. The bottom sleeve 6 acts as a protective layer, reducing direct friction and wear, and preventing wear on the limiting flange 21. The top sleeve 5, the annular sleeve 4, and the bottom sleeve 6 are integrally formed to form a sleeve assembly that fits onto the water supply pipe 2. This not only provides anti-wear protection but also works with the leak-proof component 3 to prevent leakage. The connection between the bottom sleeve 6 and the annular sleeve 4 can be achieved using various methods, such as adhesive bonding, threaded connection, or other suitable connection methods.

[0055] In summary, the washing arm 1 of the present invention is rotatably connected to the water supply pipe 2. There is a gap between the washing arm 1 and the water supply pipe 2. When the washing arm 1 rotates, water will leak at the connection between the washing arm 1 and the water supply pipe 2. The presence of the internal annular flange 31 increases the path length of water flow through the connection and shortens the distance of the gap between the washing arm 1 and the water supply pipe 2, thereby reducing the possibility of leakage.

[0056] The above are merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
