[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Please refer to the following Figures 1-6 A nozzle assembly 100 according to an embodiment of the present invention is described.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 According to an embodiment of the present utility model, the nozzle assembly 100 is applied to a dishwasher 1000 . The nozzle assembly 100 includes: a nozzle 10 , a supply pipe 20 and a connecting piece 30 .

[0035] Specifically, the nozzle 10 has a nozzle 111, and the nozzle 10 includes a connecting pipe portion 11, and the connecting pipe portion 11 forms a gas channel 112 connected to the nozzle 111; the supply pipe 20 has a first end, the first end is connected to the connecting pipe portion 11, and a boss 21 is formed on the outer peripheral surface of the first end; the connecting member 30 is formed in an annular shape and is sleeved on the outer side of the first end, and the connecting member 30 is formed with an abutment portion 31, and the abutment portion 31 is provided on the side of the boss 21 at the first end that is away from the nozzle 111 in the axial direction (such as Figure 3 The upper side of the boss 21 shown in the figure) is adapted to abut against the boss 21 in the axial direction at the first end.

[0036] Among them, a protrusion 33 is formed on one of the nozzle 10 and a groove 114 is formed on the other, that is, the protrusion 33 can be formed on the nozzle 10 and the groove 114 can be formed on the connecting member 30, or the protrusion 33 can be formed on the connecting member 30 and the groove 114 can be formed on the nozzle 10. The connecting member 30 can rotate relative to the nozzle 10 between a locked position and an unlocked position. In the locked position, the protrusion 33 cooperates with the groove 114 to fix the supply pipe 20 to the nozzle 10. In the unlocked position, the protrusion 33 withdraws from the groove 114, and the supply pipe 20 and the connecting member 30 can be separated.

[0037] For example, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the connecting pipe portion 11 of the nozzle 10 extends in the vertical direction. A gas passage 112 extending in the vertical direction is defined inside the connecting pipe portion 11. The lower end of the gas passage 112 communicates with the nozzle opening 111. The lower end of the supply pipe 20 is the first end. An annular boss 21 is formed on the outer peripheral surface of the first end. The connecting member 30 is formed in an annular shape. The connecting member 30 is sleeved on the radially outer side of the first end. An abutting portion 31 is formed on the connecting member 30. The lower side of the abutting portion 31 abuts against the upper side surface of the boss 21. There is a clamping groove 114 on the nozzle 10 and a clamping projection 33 on the connecting member 30. Preferably, the nozzle 10 is made of plastic, which can reduce the weight of the nozzle 10, thereby reducing the weight of the nozzle assembly 100 and facilitating the installation of the nozzle assembly 100.

[0038] The nozzle 10 is a steam nozzle 10. The supply pipe 20 is connected to a steam source. Steam is sprayed from the nozzle opening 111 of the nozzle 10 through the supply pipe 20 into the cleaning cavity of the dishwasher 1000, thereby cleaning items such as tableware and chopsticks in the cleaning cavity. When installing the nozzle assembly 100, first, the connecting member 30 is sleeved on the radially outer side of the first end of the supply pipe 20, and the boss 21 is located below the abutting portion 31. Then, the connecting member 30 is disposed on the upper side of the nozzle 10. The connecting member 30 is in an unlocked position relative to the nozzle 10. After that, the connecting member 30 is rotated until the clamping projection 33 cooperates with the clamping groove 114. At this time, the connecting member 30 is in a locked position relative to the nozzle 10, and the installation of the nozzle assembly 100 is completed.

[0039] For the nozzle assembly 100 of the present utility model, the connecting member 30 is provided. The connecting member 30 can strengthen the connection strength between the supply pipe 20 and the nozzle 10, thereby ensuring the connection reliability between the supply pipe 20 and the nozzle 10 and effectively preventing the separation of the supply pipe 20 and the nozzle 10. At the same time, the connecting member 30 rotates to make the clamping projection 33 cooperate with the clamping groove 114, thereby realizing the locking of the connecting member 30 and the nozzle 10. This installation form is simple and convenient to operate, thus saving assembly time and improving assembly efficiency. Moreover, the boss 21 abuts against the abutting portion 31 in the axial direction of the supply pipe 20, thereby ensuring the sealing between the boss 21 and the connecting member 30, and further effectively preventing the leakage of gas in the gas passage 112. Therefore, the use safety of the nozzle assembly 100 can be ensured.

[0040] For the nozzle assembly 100 according to the embodiment of the present utility model, the connecting member 30 is provided, which can ensure the connection reliability between the supply pipe 20 and the nozzle 10, effectively prevent the separation of the supply pipe 20 and the nozzle 10, save the assembly time between the supply pipe 20 and the nozzle 10, improve the assembly efficiency, and ensure the sealing effect between the supply pipe 20 and the nozzle 10.

[0041] According to some embodiments of the present utility model, with reference to Figure 1 and Figure 4, the supply pipe 20 is a flexible pipe. Thus, the flexible pipe can facilitate the installation of the first end of the supply pipe 20 and the connecting member 30, so that the supply pipe 20 can be properly installed with the connecting member 30. At the same time, the gap between the supply pipe 20 and the connecting member 30 can be reduced, thereby ensuring the sealing effect between the supply pipe 20 and the connecting member 30. Preferably, the supply pipe 20 can be a rubber part. Rubber parts are simple in material and convenient for production, so they can be used in batches. At the same time, the rubber pipe can be compressed, which is convenient for the installation of the supply pipe 20 and the connecting member 30. In addition, the airtightness can be effectively guaranteed. The supply pipe 20 can be a silica gel pipe, which can withstand high-temperature steam.

[0042] Furthermore, as shown in Figure 1 and Figure 4 , the boss 21 has two notches on the outer peripheral surface of the first end. The two notches divide the boss 21 into two parts. When the supply pipe 20 and the connecting member 30 are assembled, it can have a pre-installation effect, thus facilitating the assembly of the supply pipe 20 and the connecting member 30.

[0043] According to some alternative embodiments of the present invention, referring to Figure 2 and Figure 3 , the connecting pipe portion 11 is inserted into the first end and is in interference fit with the inner wall of the first end. Thus, the supply pipe 20 and the connecting member 30 are sealed axially of the supply pipe 20 through the abutting portion 31, and the supply pipe 20 and the connecting pipe portion 11 are sealed axially of the supply pipe 20, thereby ensuring the sealing effect between the supply pipe 20 and the connecting pipe portion 11, effectively preventing gas from leaking between the supply pipe 20 and the connecting pipe portion 11, and further ensuring the use safety. At the same time, the plug-in connection installation form is simple and convenient to operate, thus saving the assembly time and improving the assembly efficiency.

[0044] For example, as shown in Figure 2 and Figure 3 , the connecting pipe portion 11 extends in the up and down direction. The lower end of the connecting pipe portion 11 is connected to the nozzle 10, and the upper end of the connecting pipe portion 11 is inserted into the first end.

[0045] According to some embodiments of the present invention, referring to Figure 4 , Figure 5 and Figure 6 , the abutting portion 31 extends circumferentially along the first end into a ring shape. The abutting portion 31 is sleeved on the first end and is in interference fit with the outer peripheral surface of the first end. Thus, the connection reliability between the abutting portion 31 and the first end can be ensured, so that the separation of the boss 21 and the abutting portion 31 can be prevented, and further the connection reliability between the supply pipe 20 and the connecting member 30 can be ensured.

[0046] According to some embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 6, on the side of the connecting member 30 facing the nozzle 10 (such as Figure 6 shown in the lower side of the connecting member 30), there is a convex portion 32 extending axially along the connecting pipe portion 11 towards the nozzle opening 111. A locking projection 33 is provided on the convex portion 32, and the locking projection 33 extends towards the center of the connecting pipe portion 11 in the radial direction of the connecting pipe portion 11. Thus, the convex portion 32 can provide a setting position for the locking projection 33, facilitating the arrangement of the locking projection 33. At the same time, the locking projection 33 extends inwards, making full use of the space defined inside the connecting member 30, thereby reducing the overall volume of the connecting member 30.

[0047] For example, as shown in Figure 2 , Figure 5 and Figure 6 shown, the lower side of the connecting member 30 forms a convex portion 32. The convex portion 32 is formed in an annular shape along the circumferential direction of the connecting pipe portion 11. The locking projection 33 is provided on the inner side wall of the convex portion 32. One end of the locking projection 33 is connected to the inner side wall of the convex portion 32, and the other end of the locking projection 33 extends towards the center of the connecting pipe portion 11.

[0048] According to some alternative embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 6 , the locking projection 33 includes: a main body 331 and a limiting convex portion 332. The limiting convex portion 332 is formed on the side of the main body 331 facing the supply pipe 20 (such as Figure 6 shown in the upper side of the main body 331), and protrudes towards the supply pipe 20. A recessed limiting groove 1141 is provided in the side wall of the card slot 114. In the locked position, the limiting convex portion 332 is engaged in the limiting groove 1141. Thus, the main body 331 provides a setting position for the limiting convex portion 332, facilitating the arrangement of the limiting convex portion 332. At the same time, the limiting convex portion 332 cooperates with the recessed limiting groove 1141, effectively preventing the limiting convex portion 332 from disengaging from the limiting groove 1141, thereby ensuring the reliability of the cooperation between the limiting convex portion 332 and the limiting groove 1141, and thus ensuring the reliability of the cooperation between the connecting member 30 and the nozzle 10.

[0049] For example, as shown in Figure 2 , Figure 5 and Figure 6 shown, the main body 331 extends along the circumferential direction of the convex portion 32. The limiting convex portion 332 is provided on the upper side of the main body 331, and the limiting convex portion 332 protrudes above the main body 331. An upwardly recessed limiting groove 1141 is provided in the side wall of the card slot 114. When the connecting member 30 is in the locked position relative to the nozzle 10, the limiting projection is engaged in the limiting groove 1141.

[0050] According to some alternative embodiments of the present invention, referring to Figure 2 , Figure 5 and Figure 6, in the axial direction of the connecting pipe portion 11, a guiding inclined surface 3321 is formed on the surface of the limiting convex portion 332 facing away from the main body 331 (such as the upper surface of the limiting convex portion 332 shown in Figure 5 ). In the direction from the opening of the card slot 114 towards the bottom wall of the card slot 114, the guiding inclined surface 3321 extends obliquely away from the main body 331 along the axial direction of the connecting pipe portion 11. Thus, when the clamping protrusion 33 of the connecting member 30 cooperates with the card slot 114 of the nozzle 10, the guiding inclined surface 3321 can reduce the resistance of the clamping protrusion 33 cooperating with the side wall of the card slot 114, thereby facilitating the cooperation between the clamping protrusion 33 and the card slot 114, and further facilitating the installation of the connecting member 30 and the nozzle 10.

[0051] For example, as shown in Figure 2 , Figure 5 and Figure 6 , the upper surface of the limiting convex portion 332 is formed with a guiding inclined surface 3321, and in the direction from the opening of the card slot 114 towards the bottom wall of the card slot 114, the guiding inclined surface 3321 extends obliquely downward.

[0052] According to some alternative embodiments of the present utility model, referring to Figure 2 , Figure 5 and Figure 6 , on the side of the main body 331 facing away from the limiting convex portion 332 (such as the lower side of the main body 331 shown in Figure 6 ), there is provided a reinforcing rib 3311, and the reinforcing rib 3311 extends in the radial direction of the connecting pipe portion 11. Thus, the reinforcing rib 3311 can strengthen the strength of the main body 331, thereby strengthening the strength of the clamping protrusion 33, and further preventing the clamping protrusion 33 from breaking during the cooperation with the card slot 114, so as to ensure the service life of the connecting member 30.

[0053] For example, as shown in Figure 2 , Figure 5 and Figure 6 , the lower side of the main body 331 is provided with a reinforcing rib 3311, the reinforcing rib 3311 extends in the radial direction of the connecting pipe portion 11, two reinforcing ribs 3311 are provided, and the two reinforcing ribs 3311 are arranged at intervals in the circumferential direction of the connecting pipe portion 11.

[0054] According to some embodiments of the present utility model, referring to Figure 2 and Figure 3 , the outer surface of the connecting pipe portion 11 is provided with a clamping portion 113, and the clamping portion 113 includes: a first convex rib 1131 and a second convex rib 1132, the first convex rib 1131 extends in the circumferential direction of the connecting pipe portion 11; one end of the second convex rib 1132 (such as the upper end of the second convex rib 1132 shown in Figure 2 ) is connected to one end of the first convex rib 1131, and the other end (such as Figure 2The lower end of the second rib 1132 (as shown) extends along the axial direction of the connecting pipe portion 11 away from the first end, and the first rib 1131 and the second rib 1132 cooperate to define a card slot 114 that is open on one side in the circumferential direction of the connecting pipe portion 11.

[0055] In this way, the first rib 1131 and the second rib 1132 cooperate to form the card slot 114. The structural forms of the first rib 1131 and the second rib 1132 are simple, so that the processing of the connecting pipe portion 11 can be facilitated. At the same time, there is no need to additionally process the card slot 114, thus saving processing steps. In addition, one side of the card slot 114 is open, so that it can be ensured that the card projection 33 can normally enter the card slot 114 through the open port and cooperate with the limit slot 1141, and further, it can be ensured that the connecting member 30 can be locked with the nozzle 10.

[0056] For example, as Figure 2 and Figure 3 shown, the first rib 1131 extends along the circumferential direction of the connecting pipe portion 11, the second rib 1132 extends in the up and down direction, the upper end of the second rib 1132 is connected to one end of the first rib 1131, the first rib 1131 and the second rib 1132 form an L-shaped structure, and the first rib 1131 and the second rib 1132 define a card slot 114 that is open in the circumferential direction of the connecting pipe portion 11.

[0057] According to some alternative embodiments of the present invention, referring to Figure 2 and Figure 3 , the clamping portion 113 further includes: a third rib 1133, the third rib 1133 is connected to the other end of the second rib 1132 (such as Figure 3 shown, the lower end of the second rib 1132), the third rib 1133 is formed in a ring shape around the circumferential direction of the connecting pipe portion 11, and the first rib 1131, the second rib 1132 and the third rib 1133 enclose the card slot 114. Thus, the structural form of the third rib 1133 is simple, so that the processing of the connecting pipe portion 11 can be facilitated. At the same time, the third rib 1133 is connected to the second rib 1132, so that the clamping portion 113 can be formed as a whole, and further, the strength of the clamping portion 113 can be ensured, and the clamping portion 113 can be effectively prevented from being damaged.

[0058] For example, as Figure 2 and Figure 3 shown, the third rib 1133 is connected to the lower end of the second rib 1132, and the third rib 1133 is formed in a ring shape around the radial outer side of the connecting pipe portion 11.

[0059] According to some embodiments of the present invention, referring to Figure 3 and Figure 6, the number of the clamping protrusions 33 is multiple, that is to say, the number of the clamping protrusions 33 can be two, three, four or more. The multiple clamping protrusions 33 are arranged at intervals along the circumferential direction of the convex portion 32, and the number of the clamping protrusions 33 corresponds to the number of the clamping grooves 114 one by one. Thus, the multiple clamping protrusions 33 cooperate with the multiple clamping grooves 114, which can ensure that there are multiple fitting points between the connecting member 30 and the nozzle 10, thereby effectively preventing the separation of the connecting member 30 and the nozzle 10.

[0060] For example, as Figure 3 and Figure 6 shown, the number of the clamping protrusions 33 is two. The two clamping protrusions 33 are arranged at intervals along the circumferential direction of the convex portion 32. The number of the clamping portions 113 is two, and the two clamping portions 113 define two clamping grooves 114.

[0061] The dishwasher 1000 according to the second aspect embodiment of the present invention, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , includes the nozzle assembly 100 of the first aspect of this embodiment.

[0062] The dishwasher 1000 according to the embodiment of the present invention, by providing the nozzle assembly 100 of the first aspect embodiment above and providing the connecting member 30, can ensure the connection reliability between the supply pipe 20 and the nozzle 10, effectively prevent the separation of the supply pipe 20 and the nozzle 10. At the same time, it can save the assembly time of the supply pipe 20 and the nozzle 10, improve the assembly efficiency, and can also ensure the sealing effect between the supply pipe 20 and the nozzle 10.
