Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen appliance technology, and in particular to a spray assembly and a dishwasher. Background Technology
[0002] Dishwashers typically have three spray arms and two dish racks. The middle spray arm is fixed to the upper dish rack and connects to the internal water pipe via a water hose connector. Current dishwashers generally do not allow the upper dish rack to be removed for operation. This is because removing the upper dish rack prevents the middle spray arm from being secured, causing the dishwasher to malfunction. Furthermore, because the upper dish rack occupies a significant amount of space inside the dishwasher, its inability to be removed prevents the placement of large tableware such as large pots and pans, thus limiting the dishwasher's applicability to large items. Summary of the Invention
[0003] The main objective of this invention is to provide a spray assembly and a dishwasher that solves the problem that existing dishwashers cannot clean large tableware.
[0004] To achieve the above objectives, the present invention proposes a spray assembly for use in a dishwasher, the dishwasher including an inner water pipe and a water pipe connector disposed on the inner water pipe, the spray assembly comprising:
[0005] The nozzle body is provided with a connector, which is inserted and connected to the water pipe connector.
[0006] A locking member, movably disposed on the nozzle body, has a fixed position for locking the nozzle body to the water pipe connector, and an unlocking position for separating the nozzle body from the water pipe connector; and
[0007] An elastic element is disposed between the nozzle body and the locking element, and the elastic element is used to drive the locking element to remain in the fixed position.
[0008] In one embodiment, the locking member is sleeved on the nozzle body, and a receiving groove is formed between the locking member and the nozzle body. The elastic member is telescopically disposed in the receiving groove along the axial direction of the locking member. One end of the elastic member extending along the axial direction of the locking member abuts against the locking member, and the other end abuts against the nozzle body.
[0009] In one embodiment, the elastic element is a spring, which is sleeved on the nozzle body. In the unlocked position, the elastic element is in a compressed state.
[0010] In one embodiment, a limiting baffle for blocking the locking member is provided on the outer peripheral wall of the nozzle body, and the locking member is located between the limiting baffle and the water pipe joint.
[0011] In one embodiment, the locking member is sleeved on the nozzle body, and the spray assembly further includes a limiting member, which is movably disposed on the mating head along the radial direction of the locking member; in the fixed position, the locking member locks the limiting member, and the limiting member limits and fixes the mating head on the water pipe joint; in the unlocked position, the locking member releases the locking of the limiting member, and the limiting member cancels the limitation on the position of the water pipe joint, so that the water pipe joint can be separated from the nozzle body.
[0012] In one embodiment, the connector is hollow, and a limiting hole extending through its thickness is provided on the side wall of the connector. The limiting member is movably disposed in the limiting hole along the radial direction of the locking member, and the water pipe connector is provided with a limiting groove. In the fixed position, part of the limiting member moves from the limiting hole to the limiting groove to limit and fix the connector to the water pipe connector. In the unlocked position, the limiting member in the limiting groove moves to the limiting hole to release the limitation on the position of the water pipe connector.
[0013] In one embodiment, the locking member is sleeved on the mating head and can move back and forth along the axial direction of the mating head, so that the locking member can switch between the fixed position and the unlocked position. The locking member is provided with a locking part; in the fixed position, the locking part abuts against the limiting member in the limiting hole and the limiting groove; in the unlocked position, the locking part avoids the limiting hole to release the limiting member in the limiting hole.
[0014] In one embodiment, there are multiple limiting holes, which are arranged sequentially at intervals around the circumference of the connector, and each limiting hole is provided with a corresponding limiting member.
[0015] In one embodiment, the limiting member is a ball bearing, which is movably disposed within the limiting hole along the depth direction of the limiting hole.
[0016] In one embodiment, a limiting protrusion is provided on the wall of the limiting hole. The limiting protrusion is located at one end of the limiting hole near the inner cavity of the connector, and the limiting protrusion is used to limit the ball within the limiting hole.
[0017] In one embodiment, the limiting protrusion is arranged in a ring around the wall of the limiting hole so that the limiting protrusion has a hole diameter, the minimum value of which is smaller than the diameter of the ball.
[0018] In one embodiment, the water pipe connector includes a connector body and a plug on one side of the connector body. The plug is inserted into the inner cavity of the connector. An annular groove is provided on the outer peripheral wall of the plug. The dishwasher also includes a sealing ring, which is fitted onto the plug and located in the annular groove. The sealing ring is used to seal the gap between the plug and the connector.
[0019] In one embodiment, the limiting groove is provided on the outer peripheral wall of the connector, and the limiting groove is located between the annular groove and the connector body.
[0020] In one embodiment, the limiting groove is arranged in a ring around the outer peripheral wall of the connector.
[0021] In one embodiment, the nozzle body includes an adapter plug, a rotating component, and a spray head connected in sequence. The connector is located at the end of the adapter plug away from the rotating component. The adapter plug, the rotating component, and the spray head are connected in sequence, and the spray head is rotatably mounted on the rotating component.
[0022] The present invention also proposes a dishwasher, the dishwasher including an inner water pipe, a water pipe connector and a spray assembly as described above, the water pipe connector being connected to the water outlet end of the inner water pipe; the spray assembly is provided with a connector, the connector being inserted and connected to the water pipe connector.
[0023] In one embodiment, the water pipe connector is located in the middle of the inner water pipe, and the nozzle body of the spray assembly has a spray hole at one end away from the water pipe connector. The spray hole is used to spray water in a direction away from the inner water pipe.
[0024] The spray assembly of this application includes a nozzle body, a locking member, and an elastic member. A connector on the spray body is inserted into a water pipe connector. The locking member has a fixed position and an unlocked position, allowing the nozzle body to be easily fixed or separated from the water pipe connector. The elastic member drives the locking member to remain in the fixed position, ensuring the nozzle body can be stably installed on the water pipe connector. Through the cooperation of the nozzle body, locking member, and elastic member, the spray assembly is easily assembled and disassembled with the water pipe connector. When the dishwasher needs to clean large dishes, the upper rack can be removed, and the middle spray arm can be detached. The spray assembly of this application can then be installed on the dishwasher's water pipe connector to replace the middle spray arm. This allows the dishwasher to continue operating normally after the upper rack is removed, and the dishwasher with the upper rack removed allows large dishes to be placed inside, enabling the dishwasher to clean large dishes, thus improving its applicability.

[0040] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0042] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0043] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0044] Existing dishwashers typically include a housing, a water hose assembly, a spray arm assembly, and a dish rack assembly. The water hose assembly includes an inner water hose and a water hose connector, with the connector connecting to the outlet of the inner water hose. The spray arm assembly includes an upper spray arm, a middle spray arm, and a lower spray arm, arranged sequentially from top to bottom within the housing. Both the upper and lower spray arms are connected to the inner water hose, and the middle spray arm is connected to the inner water hose via the water hose connector. The dish rack assembly includes an upper dish rack and a lower dish rack, which are detachably mounted within the housing so that they can be removed. The upper dish rack is positioned above the lower dish rack, and the middle spray arm is positioned between the upper and lower dish racks and connected to the upper dish rack for fixation. The middle spray arm typically sprays water upwards to clean the dishes in the upper dish rack.
[0045] Therefore, it is evident that existing dishwashers typically require the spray arm to be fixed to the upper rack for proper operation. Current dishwashers do not allow the upper rack to be removed before operation, as this prevents the spray arm from being secured and the dishwasher from functioning correctly. Furthermore, because the upper rack occupies a significant amount of space within the dishwasher, its inability to be removed prevents the placement of large tableware (such as large pots and pans), thus hindering the dishwasher's ability to clean such items and limiting its applicability.
[0046] The present invention provides a spray assembly and a dishwasher including the spray assembly, which can solve the problem that existing dishwashers cannot clean large tableware.
[0047] Please see Figures 1 to 4 In one embodiment of the spray assembly 10 of the present invention, the spray assembly 10 is applied to a dishwasher, the dishwasher including an inner water pipe 500 and a water pipe connector 600 disposed on the inner water pipe 500. The spray assembly 10 includes a nozzle body 100, a locking member 200, and an elastic member 300. The nozzle body 100 is provided with a connector 111, which is inserted into the water pipe connector 600. The locking member 200 is movably disposed on the nozzle body 100, and has a fixed position for locking the nozzle body 100 to the water pipe connector 600, and an unlocking position for separating the nozzle body 100 from the water pipe connector 600. The elastic member 300 is disposed between the nozzle body 100 and the locking member 200, and the elastic member 300 is used to drive the locking member 200 to remain in the fixed position (e.g., ...). Figure 8 and Figure 10 (As shown).
[0048] It is understandable that the connector 111 is inserted into the water pipe connector 600. Either the connector 111 is inserted into the water pipe connector 600, or the water pipe connector 600 is inserted into the connector 111; the specific arrangement is not limited here. The nozzle body 100 is provided with a spray hole 132, which is connected to the inner water pipe 500 through the water pipe connector 600, allowing the spray hole 132 to spray water outwards.
[0049] Furthermore, the locking member 200 can be movably disposed on the nozzle body 100 in various ways. For example, the locking member 200 can be pulled out and disposed on the nozzle body 100; or, the locking member 200 can be rotatably disposed on the nozzle body 100; or, the locking member 200 can be slidably disposed on the nozzle body 100. The specific method is not limited here. The locking member 200 moves on the nozzle body 100, allowing it to switch between a fixed position and an unlocked position. When the locking member 200 is in the fixed position, it locks the nozzle body 100 to the water pipe connector 600, allowing the spray assembly 10 to be installed on the water pipe connector 600. When the locking member 200 is in the unlocked position, the nozzle body 100 can be separated from the water pipe connector 600, allowing the spray assembly 10 to be detached from the water pipe connector 600. This design facilitates the assembly and disassembly of the spray assembly 10.
[0050] Furthermore, the elastic element 300 can be of various types, including springs or sheet springs, and is not specifically limited here. The elastic element 300 is used to drive the locking element 200 to remain in a fixed position. When no external force is applied to the elastic element 300, the locking element 200 can move to a fixed position that locks the nozzle body 100 onto the water pipe connector 600, thereby ensuring that the nozzle body 100 is stably installed on the water pipe connector 600, thus improving the stability of the nozzle body 100 installation.
[0051] The spray assembly 10 of this application includes a nozzle body 100, a locking member 200, and an elastic member 300. The connector 111 on the spray body is inserted and connected to the water pipe connector 600. The locking member 200 has a fixed position and an unlocked position so that the nozzle body 100 can be easily fixed or separated from the water pipe connector 600. The elastic member 300 is used to drive the locking member 200 to remain in the fixed position so as to ensure that the nozzle body 100 can be stably installed on the water pipe connector 600. Through the cooperation of the nozzle body 100, the locking member 200, and the elastic member 300, the spray assembly 10 can be easily assembled and disassembled with the water pipe connector 600. When the dishwasher needs to clean large dishes 11, the upper rack can be removed, and the middle spray arm can be detached. The spray assembly 10 of this application can then be installed on the dishwasher's water pipe connector 600 to replace the middle spray arm. This allows the dishwasher to continue operating normally after the upper rack is removed, and the dishwasher with the upper rack removed can accommodate large dishes 11, enabling it to clean them. This improves the dishwasher's versatility. It is understandable that a dishwasher capable of cleaning large dishes can also clean small dishes; that is, when the dishwasher uses the spray assembly 10 of this application, it can clean both large and small dishes, thus enhancing its versatility.
[0052] Please see Figure 4 , Figure 8 and Figure 9 In one embodiment, the locking member 200 is sleeved on the nozzle body 100, and a receiving groove 210 is formed between the locking member 200 and the nozzle body 100. The elastic member 300 is telescopically disposed in the receiving groove 210 along the axial direction of the locking member 200. One end of the elastic member 300 extending along the axial direction of the locking member 200 abuts against the locking member 200, and the other end abuts against the nozzle body 100.
[0053] It is understood that the locking member 200 has a hollow structure and is open at both ends. A receiving groove 210 is formed between the inner wall surface of the locking member 200 and the outer wall surface of the nozzle body 100. The receiving groove 210 can be arranged in a ring around the inner wall surface of the locking member 200. Correspondingly, the elastic member 300 can also be arranged in a ring. Of course, the receiving groove 210 can also be formed by a part of the inner wall surface of the locking member 200 and a part of the outer wall surface of the nozzle body 100, so that the receiving groove 210 is not arranged in a ring. For example, the receiving groove 210 is arranged in a square shape, etc. The specific arrangement is not limited here. The shape of the elastic member 300 corresponds to the shape of the receiving groove 210.
[0054] In this embodiment, a first limiting platform is protruding on the inner wall surface of the locking member 200. The first limiting platform is located at one end of the inner wall surface of the locking member 200 near the water pipe connector 600. A second limiting platform is protruding on the outer wall surface of the nozzle body 100. The first limiting platform and the second limiting platform are spaced apart along the axial direction of the locking member 200. An elastic member 300 is located between the first limiting platform and the second limiting platform. One end of the elastic member 300 abuts against the first limiting platform, and the other end abuts against the second limiting platform.
[0055] When an external force is applied to the locking member 200 and moves it from the fixed position to the unlocked position, the first limiting platform compresses the elastic member 300, causing the elastic member 300 to undergo elastic deformation. When the external force stops acting on the locking member 200, the compressed elastic member 300 pushes the locking member 200 to move, and the elastic member 300 returns to its initial length. This allows the locking member 200 to be telescopically disposed within the receiving groove 210. The elastic member 300 allows the locking member 200 to move and switch between the fixed position and the unlocked position through telescopic changes. This simplifies the way the locking member 200 moves and switches, optimizes the structure of the spray assembly 10, and also facilitates the assembly and disassembly of the nozzle body 100 and the water pipe connector 600, which helps to improve the installation and disassembly efficiency of the nozzle body 100.
[0056] Please see Figure 10 and Figure 11In one embodiment, the elastic element 300 is a spring, which is sleeved on the nozzle body 100. In the unlocked position, the elastic element 300 is in a compressed state. It is understood that an annular receiving groove 210 is formed between the inner wall surface of the locking member 200 and the outer wall surface of the nozzle body 100. The spring is sleeved on the nozzle body 100. When the locking member 200 is in the unlocked position, one end of the spring abuts against the first limiting platform in the inner cavity of the locking sleeve, and the other end of the spring abuts against the second limiting platform on the outer peripheral wall of the nozzle body 100. The spring is in a compressed state. When the external force stops acting on the locking member 200, the compressed spring will push the locking member 200 to move to a fixed position so that the locking member 200 can be kept in a fixed position. This ensures that the locking member 200 can lock and fix the nozzle body 100 on the water pipe connector 600, thereby improving the stability of the nozzle body 100 installed on the water pipe connector 600, that is, ensuring the stability of the spray assembly 10 installed on the water pipe connector 600.
[0057] Please see Figure 4 , Figure 8 and Figure 10 In one embodiment, the outer peripheral wall of the nozzle body 100 is provided with a limiting baffle 140 for blocking the locking member 200, and the locking member 200 is disposed between the limiting baffle 140 and the water pipe connector 600.
[0058] Understandably, when the locking member 200 moves from the fixed position to the unlocked position, the limiting baffle 140 can block the movement of the locking member 200 to prevent the locking member 200 from coming off the nozzle body 100. At the same time, it also ensures that the locking member 200 can reach the unlocked position with the minimum movement distance. This setting not only optimizes the structure of the nozzle body 100, but also improves the stability of the locking member 200 moving on the nozzle body 100.
[0059] Please see Figures 6 to 9 In one embodiment, the locking member 200 is sleeved on the nozzle body 100, and the spray assembly 10 further includes a limiting member 400, which is movably disposed on the connector 111 along the radial direction of the locking member 200. In the fixed position, the locking member 200 locks the limiting member 400, and the limiting member 400 limits and fixes the connector 111 on the water pipe connector 600. In the unlocked position, the locking member 200 releases the locking of the limiting member 400, and the limiting member 400 removes the limitation on the position of the water pipe connector 600, so that the water pipe connector 600 can be separated from the nozzle body 100.
[0060] It is understood that the locking member 200 is sleeved on the nozzle body 100, the locking member 200 is movably disposed on the nozzle body 100 along its axis, and the limiting member 400 is movably disposed on the connector 111 along the radial direction of the locking member 200. When the locking member 200 moves to the fixed position, it locks the limiting member 400. The limiting member 400 moves radially along the locking member 200 to limit the water pipe connector 600 and the coupling 111, so that the coupling 111 is fixed on the water pipe connector 600. When the locking member 200 moves to the unlocked position, it releases the locking member 200 from the limiting member 400. The limiting member 400 moves radially along the locking member 200 to separate from the water pipe connector 600, and the limiting member 400 releases its limitation on the water pipe connector 600. At this time, the water pipe connector 600 can separate from the coupling 111, thereby allowing the coupling 111 of the nozzle body 100 to separate from the water pipe connector 600. This design simplifies the locking and unlocking of the limiting member 400 by the locking member 200, which helps to simplify the structure of the spray assembly 10.
[0061] Please see Figure 5 , Figure 6 , Figure 8 and Figure 10 In one embodiment, the connector 111 is hollow, and a limiting hole 112 extending through its thickness is provided on the side wall of the connector 111. The limiting member 400 is movably disposed in the limiting hole 112 along the radial direction of the locking member 200. The water pipe connector 600 is provided with a limiting groove 621. In the fixed position, part of the limiting member 400 moves from the limiting hole 112 into the limiting groove 621 to limit and fix the connector 111 on the water pipe connector 600. In the unlocked position, the limiting member 400 in the limiting groove 621 moves into the limiting hole 112 to release the limitation on the position of the water pipe connector 600.
[0062] It is understood that the shape of the limiting hole 112 is not limited; it can be cylindrical or rectangular. When the locking member 200 moves to the fixed position, a portion of the limiting members 400 moves into the limiting groove 621, while the other portion remains in the limiting hole 112. That is, a portion of the limiting members 400 moves into the limiting groove 621 to limit the position of the water pipe connector 600, while the other portion remains in the limiting hole 112 to limit the position of the connector 111, thus fixing the connector 111 to the water pipe connector 600. When the locking member 200 moves to the unlocked position, the limiting members 400 in the limiting groove 621 move radially along the locking member 200 into the limiting groove 621, releasing the limiting members 400 from the water pipe connector 600, thereby allowing the water pipe connector 600 to separate from the connector 111. It can be seen that by setting a limiting hole 112 on the side wall of the connector 111 and a limiting groove 621 on the water pipe connector 600, the limiting part 400 can be moved and limited in a simple way, which is conducive to simplifying the structure of the spray assembly 10 and also facilitates the assembly and disassembly of the spray assembly 10.
[0063] Please see Figures 8 to 11 In one embodiment, the locking member 200 is sleeved on the connector 111 and can move back and forth along the axial direction of the connector 111, so that the locking member 200 can switch between the fixed position and the unlocked position. The locking member 200 is provided with a locking part 220. In the fixed position, the locking part 220 abuts against the limiting member 400 in the limiting hole 112 and the limiting groove 621. In the unlocked position, the locking part 220 avoids the limiting hole 112 to release the limiting member 400 in the limiting hole 112.
[0064] Understandably, when the locking member 200 is in the fixed position, the locking part 220 presses against the limiting member 400, so that the limiting member 400 can be held within the limiting hole 112 of the connector 111 and the limiting groove 621 of the water pipe connector 600. The locking part 220 can cover the limiting hole 112. Of course, the locking part 220 can also be located within the limiting hole 112; the specific location is not limited here. When the locking member 200 is in the unlocked position, the locking part 220 is located on one side of the limiting hole 112 to avoid the limiting hole 112. At this time, the locking part 220 separates from the limiting member 400, thereby allowing the limiting member 400 to move out of the limiting groove 621. Therefore, the locking part 220 locks the limiting member 400 through the cap limiting hole 112, and the locking part 220 releases the locking of the limiting member 400 by avoiding the limiting hole 112. The locking and unlocking methods of the locking part 220 are simple, which helps to simplify the structure of the spray assembly 10, and also facilitates the assembly and disassembly of the spray assembly 10.
[0065] In one embodiment, there are multiple limiting holes 112, which are arranged sequentially at intervals around the circumference of the connector 111. Each limiting hole 112 contains a corresponding limiting member 400. This arrangement ensures that the limiting holes 112 are evenly distributed on the outer peripheral wall of the connector 111, and correspondingly, the limiting holes 112 are also evenly distributed on the connector 111, thus ensuring the stability of the spray assembly 10 installed on the water pipe connector 600.
[0066] In one embodiment, the limiting member 400 is a ball bearing, which is movably disposed within the limiting hole 112 along the depth direction of the limiting hole 112. It is understood that by setting the limiting member 400 as a ball bearing, the structure of the limiting member 400 is simplified, thereby making the spray assembly 10 easier to manufacture. Simultaneously, the ball bearing can roll within the limiting hole 112, allowing the limiting member 400 to move more smoothly within the limiting hole 112, thus improving the smoothness of the limiting member 400's movement.
[0067] Please see Figures 6 to 9 In one embodiment, a limiting protrusion 113 is provided on the wall of the limiting hole 112. The limiting protrusion 113 is located at one end of the limiting hole 112 near the inner cavity of the connector 111. The limiting protrusion 113 is used to limit the ball within the limiting hole 112.
[0068] Understandably, the protrusion is located at one end of the limiting hole 112 near the inner cavity of the connector 111, that is, the limiting protrusion 113 is located inside the limiting hole 112. By setting the limiting protrusion 113, the position of the ball is limited. The shape of the limiting protrusion 113 is not limited; it can be square, annular, or other shapes, as long as it can confine the ball within the limiting hole 112. By setting the limiting protrusion 113 to confine the ball within the limiting hole 112, it prevents the ball from falling into the connector 111 from the outside of the limiting hole 112, that is, it prevents the ball from falling out of the limiting hole 112 when the spray assembly 10 is disassembled from the water pipe connector 600, thus improving the reliability of the spray assembly 10.
[0069] In one embodiment, the limiting protrusion 113 is arranged annularly around the wall of the limiting hole 112, so that the limiting protrusion 113 has a diameter, the minimum value of which is smaller than the diameter of the ball. By setting the limiting protrusion 113 in annular shape, the structure of the limiting protrusion 113 and the limiting hole 112 is easy to manufacture. The minimum value of the diameter of the limiting protrusion 113 is equivalent to the minimum value of the limiting hole 112, that is, the minimum value of the diameter of the limiting hole 112 is smaller than the diameter of the ball. This arrangement ensures that the ball will not fall from the outside of the limiting hole 112 into the inside of the connector 111, because the ball that falls into the inner wall of the connector 111 will fall outside the nozzle body 100. Therefore, by setting the minimum diameter of the limiting protrusion 113 to be smaller than the diameter of the ball, it is possible to prevent the ball from falling out of the limiting hole 112 when the spray assembly 10 is disassembled from the water pipe connector 600, thereby improving the reliability of the spray assembly 10.
[0070] Please see Figure 3 , Figure 4 and Figure 8 In one embodiment, the water pipe connector 600 includes a connector body 610 and a plug connector 620 disposed on one side of the connector body 610. The plug connector 620 is inserted into the inner cavity of the connector 111. The outer peripheral wall of the plug connector 620 is provided with an annular groove 622. The dishwasher also includes a sealing ring 700, which is sleeved on the plug connector 620 and located in the annular groove 622. The sealing ring 700 is used to seal the gap between the plug connector 620 and the connector 111.
[0071] Understandably, the hollow design of the connector 620 allows it to connect with the connector 111. By incorporating a sealing ring 700, water is prevented from leaking out from the gap between the connector 620 and the connector 111 when the water pipe connector 600 is connected to the connector 111 of the spray assembly 10. This improves the sealing performance of the connection between the spray assembly 10 and the water pipe connector 600, thereby enhancing the reliability of the dishwasher.
[0072] Please see Figure 4 and Figure 5In one embodiment, the limiting groove 621 is disposed on the outer peripheral wall of the plug 620, and the limiting groove 621 is located between the annular groove 622 and the connector body 610. It is understood that by placing the limiting groove 621 between the annular groove 622 and the connector body 610, when water flows from the plug 620 into the connector 111, the water is blocked by the sealing ring 700 in the annular groove 622, preventing water from flowing into the limiting groove 621. This avoids the situation where water flows out of the limiting groove 621 along the limiting hole 112 to the outside of the connector 111 when the spray assembly 10 is installed on the water pipe connector 600, thereby improving the sealing performance of the connection between the spray assembly 10 and the water pipe connector 600, and thus improving the reliability of the dishwasher.
[0073] In one embodiment, the limiting groove 621 is arranged in a ring around the outer peripheral wall of the connector 620. With this arrangement, when the connector 620 is inserted into the mating connector 111, the limiting member 400 can move around the ring-shaped limiting groove 621, that is, the limiting member 400 can rotate around the outer peripheral wall of the connector 620, allowing the nozzle body 100 to rotate around the outer peripheral wall of the connector 620, thereby enabling the spray assembly 10 to be rotatably mounted on the water pipe connector 600. The rotation of the spray assembly 10 increases the spray distance and improves the spray intensity, that is, it increases the spray area and improves the spray intensity, thereby improving the cleanliness of the dishwasher's dishes.
[0074] Please see Figure 3 and Figure 4 In one embodiment, the nozzle body 100 includes an adapter plug 110, a rotating member 120, and a spray head 130 connected in sequence. The connector 111 is located at the end of the adapter plug 110 away from the rotating member 120. The adapter plug 110, the rotating member 120, and the spray head 130 are connected in sequence. The spray head 130 is rotatably mounted on the rotating member 120.
[0075] Understandably, a conventional spray head body 100 cannot rotate to spray water. However, this application incorporates a rotating component 120, allowing the spray head 130 to rotate. Thus, when the spray head body 100 is connected to the water pipe connector 600, the spray head body 100 is rotatably mounted on the water pipe connector 600. This design increases the spray area and improves the spray intensity, thereby enhancing the cleanliness of the dishwasher's dishes.
[0076] In one embodiment, the rotating component 120 includes a bearing 121 and a bearing 121 seat. The adapter plug 110, the bearing 121 seat, the bearing 121, and the spray head 130 are connected in sequence. The bearing 121 seat has a hollow structure with open ends. The adapter plug 110 is inserted into the bearing 121 seat. The bearing 121 is located on the bearing 121 seat and at the end of the bearing 121 seat away from the adapter plug 110. The spray head 130 is inserted into the shaft hole of the bearing 121. It is understood that by providing the bearing 121, the structure of the rotating component 120 is simplified; the bearing 121 is detachably mounted on the bearing 121 seat to improve the assembly efficiency of the rotating component 120; and by inserting the spray head 130 into the shaft hole of the bearing 121, the installation method of the spray head 130 and the rotating component 120 is simplified. In addition, the spray head 130 passes through the bearing 121 and is inserted into the bearing 121 seat, which helps to improve the stability of the spray head 130 installation.
[0077] Please see Figures 1 to 4 The present invention also proposes a dishwasher, which includes an inner water pipe 500, a water pipe connector 600, and a spray assembly 10 as described above. The water pipe connector 600 is connected to the water outlet end of the inner water pipe 500. The spray assembly 10 is provided with a connector 111, which is inserted and connected to the water pipe connector 600. The specific structure of the spray assembly 10 is as described in the above embodiments. Since the dishwasher adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0078] Understandably, the water pipe connector 600 is detachably and washably installed on the inner water pipe 500. Water flowing out from the outlet of the inner water pipe 500 can enter the spray assembly 10 after passing through the water pipe connector 600, so that the spray assembly 10 can spray water outward.
[0079] In one embodiment, the water pipe connector 600 is located in the middle of the inner water pipe 500, and the nozzle body 100 of the spray assembly 10 is provided with a spray hole 132 at one end away from the water pipe connector 600. The spray hole 132 is used to spray water in a direction away from the inner water pipe 500.
[0080] Understandably, the inner water pipe 500 has water outlets at both ends and in the middle. The dishwasher also includes an upper spray arm and a lower spray arm. The upper spray arm is connected to the upper water outlet of the inner water pipe 500 and is used to spray water downwards. The lower spray arm is connected to the lower water outlet of the inner water pipe 500 and is used to spray water upwards. The spray assembly 10 is located in the middle of the inner water pipe 500. The end of the spray assembly 10 facing away from the inner water pipe 500 has a spray hole 132 so that the spray hole 132 can spray water in the direction away from the inner water pipe 500, that is, the spray hole 132 can spray water in front of the middle of the inner water pipe 500.
[0081] Furthermore, in this embodiment, the dishwasher does not have an upper rack; it only has a lower rack. This results in a larger internal space, allowing large tableware 11, such as pots and pans or baking trays, to be placed on the lower rack and cleaned by the spray assembly 10. Therefore, compared to existing dishwashers, the dishwasher of this application can clean both large and small tableware, making it highly versatile.
[0082] In one embodiment, the dishwasher further includes a housing 800, the housing 800 having a loading / unloading port 810, the spray assembly 10 being disposed inside the housing 800, the nozzle body 100 having a water outlet 131, the spray holes 132 being disposed on the water outlet 131, and the outer surface of the water outlet 131 facing the loading / unloading port 810.
[0083] It is understood that the outer casing 800 includes a back panel, which is positioned opposite to the loading / unloading port 810. Tableware can be placed into or removed from the outer casing 800 through the loading / unloading port 810. An inner water pipe 500 is mounted on the back panel. The spray assembly 10 is mounted on the inner water pipe 500 via a water pipe connector 600. The spray assembly 10 includes a nozzle body 100, which has a connector 111 that is inserted into the water pipe connector 600. The outer surface of the water outlet portion 131 of the nozzle body 100 faces the loading / unloading port 810. A switch door can be installed at the loading / unloading port 810, meaning the outer surface of the water outlet portion 131 of the nozzle body 100 can face the switch door or face one side of the switch door. The water outlet portion 131 has multiple spray holes 132, allowing multiple spray holes 132 to spray water towards the switch door and one side thereof. It should be noted that the direction of the opening and closing door and one side includes not only the direction of the spray hole 132 toward the opening and closing door (from the back panel toward the loading and unloading port 810), but also the upper, lower, left, and right sides of the opening and closing door. The spray area of the spray hole 132 of the spray assembly 10 of this application is relatively large, which is beneficial to improving the cleanliness of the dishwasher when cleaning large tableware 11.
[0084] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
