[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0042] like Figures 1 to 6As shown, the embodiment of the present disclosure provides a shower head 12 for a dishwasher and a dishwasher. The gap between the first guide plate 31 and the second guide plate 32 can be adjusted by the adjustment part 40 to control the area and pressure of the water flow sprayed from the shower head 12. The functions are more diversified and the user experience is better.

[0043] like Figures 1 to 6 As shown, an embodiment of the present disclosure provides a shower head 12 for a dishwasher. The dishwasher is provided with a water pipe 11 . The shower head 12 includes: a housing 20 , a first guide plate 31 , a second guide plate 32 and an adjustment portion 40 . The shell 20 is provided with a hollow installation cavity; the first guide plate 31 is movably provided in the left half of the installation cavity; the second guide plate 32 is provided in the right half of the installation cavity relative to the first guide plate 31, and the gap between the second guide plate 32 and the first guide plate 31 defines a flow channel, which is connected to the water pipe 11; the adjustment part 40 is movably provided in the shell 20, and the position of the adjustment part 40 corresponding to the first guide plate 31 is provided with a first pushing part 411 and a first giving way part 412; wherein the adjustment part 40 can move between a first position and a second position; when the adjustment part 40 moves to the first position, the first pushing part 411 moves to the position corresponding to the first guide plate 31 to push the first guide plate 31 toward the direction of the second guide plate 32; when the adjustment part 40 moves to the second position, the first giving way part 412 moves to the position corresponding to the first guide plate 31 to give way to the first guide plate 31.

[0044] Specifically, the first guide plate 31 is plate-shaped and is positioned in the left half of the mounting cavity, parallel to the direction of water flow within the mounting cavity. The movement of the first guide plate 31 is limited to moving toward or away from the second guide plate 32. The second guide plate 32 is also plate-shaped and is positioned in the right half of the mounting cavity, parallel to the first guide plate 31. A gap exists between the second guide plate 32 and the first guide plate 31 to define a flow channel, through which water within the water pipe 11 flows and is then ejected from the shower head 12. When the dishwasher is washing dishes, the user can move the adjustment portion 40 between the first position and the second position.

[0045] like Figure 4 As shown, if the user moves the adjustment portion 40 to the first position, the first pusher 411 of the adjustment portion 40 moves to a position corresponding to the first deflector 31. At this point, the first pusher 411 pushes the first deflector 31 toward the second deflector 32, reducing the gap between the first and second deflector plates 31, thereby reducing the width of the flow channel. This allows the water in the water pipe 11 to form a fan-shaped mist when it is ejected from the shower head 12 through the flow channel, creating a water flow that covers a large cleaning area and has low spray pressure.

[0046] like Figure 6 As shown, if the user moves the adjustment portion 40 to the second position, the first clearance portion 412 of the adjustment portion 40 moves to a position corresponding to the first deflector 31. At this point, water flowing from the water pipe 11 into the flow channel pushes the first deflector 31 away from the second deflector 32, increasing the gap between the first and second deflector plates 31, thereby widening the flow channel. This creates a high-pressure water jet when the water in the water pipe 11 flows through the flow channel and exits the shower head 12, creating a water flow with a small cleaning area and high pressure.

[0047] With this arrangement, the user can adjust the gap between the first guide plate 31 and the second guide plate 32 through the adjustment portion 40 to control the area and pressure of the water flow sprayed from the shower head 12, making the functions more diversified and the user experience better.

[0048] Optionally, the housing 20 is provided with stoppers at positions corresponding to the first deflector 31 and the second deflector 32. When the first deflector 31 and the second deflector 32 move away from the mounting cavity, the stoppers can stop the first deflector 31 and the second deflector 32 to prevent the first deflector 31 and the second deflector 32 from falling out of the mounting cavity.

[0049] like Figures 3 to 6 As shown, in some embodiments, a first boss 41 is provided at a position of the adjustment portion 40 corresponding to the first guide plate 31, and the width of the first end of the first boss 41 is greater than the width of the second end, so that the first end and the second end of the first boss 41 respectively constitute a first pushing portion 411 and a first yielding portion 412.

[0050] Specifically, a first boss 41 is provided on the sidewall of the adjustment portion 40 facing the first deflector 31. The first boss 41 is tilted relative to the side surface of the first deflector 31 so that the width of the first end of the first boss 41 is greater than the width of the second end. Thus, the first end of the first boss 41 constitutes a first pushing portion 411, and the second end of the first boss 41 constitutes a first yielding portion 412. If the user moves the adjustment portion 40 to the first position, the first end of the first boss 41 moves to the position corresponding to the first deflector 31 to push the first deflector 31. If the user moves the adjustment portion 40 to the second position, the second end of the first boss 41 moves to the position corresponding to the first deflector 31 to yield to the first deflector 31.

[0051] With this arrangement, as the adjustment portion 40 moves between the first and second positions, the first deflector 31 gradually moves closer to or farther from the second deflector 32, thereby gradually reducing or increasing the flow path. For example, the user can move the adjustment portion 40 to a position intermediate between the first and second positions, causing water from the water pipe 11 to form a small fan-shaped mist when it flows through the flow path and exits the shower head 12. This creates a water flow with a moderate cleaning area and high spray pressure, further enhancing functional diversity and providing a better user experience.

[0052] like Figures 2 to 6 As shown, in some embodiments, the second guide plate 32 is movably arranged in the right half of the installation cavity; and a second pushing portion 421 and a second yielding portion 422 are provided at a position of the adjustment portion 40 corresponding to the second guide plate 32; when the adjustment portion 40 moves to the first position, the second pushing portion 421 moves to a position corresponding to the second guide plate 32 to push the second guide plate 32 toward the first guide plate 31; when the adjustment portion 40 moves to the second position, the second yielding portion 422 moves to a position corresponding to the second guide plate 32 to yield to the second guide plate 32.

[0053] Specifically, the second guide plate 32 is movably disposed in the right half of the installation cavity relative to the first guide plate 31 , and the movement direction of the second guide plate 32 is limited to approaching or moving away from the first guide plate 31 .

[0054] If the user moves the adjustment portion 40 to the first position, the second pushing portion 421 of the adjustment portion 40 moves to a position corresponding to the second guide plate 32. At this point, the second pushing portion 421 pushes the second guide plate 32 toward the first guide plate 31, thereby reducing the gap between the first and second guide plates 31, 32. If the user moves the adjustment portion 40 to the second position, the second yielding portion 422 of the adjustment portion 40 moves to a position corresponding to the second guide plate 32. At this point, water flowing from the water pipe 11 into the flow channel pushes the second guide plate 32 away from the first guide plate 31, thereby increasing the gap between the first and second guide plates 31, 32.

[0055] Such a setting can further improve the diversity of functions and provide a better user experience.

[0056] like Figures 3 to 6 As shown, in some embodiments, a second boss 42 is provided at a position corresponding to the adjustment portion 40 and the second guide plate 32, and the width of the first end of the second boss 42 is greater than the width of the second end, so that the first end and the second end of the second boss 42 constitute a second pushing portion 421 and a second yielding portion 422, respectively.

[0057] Specifically, a second boss 42 is provided on the sidewall of the adjustment portion 40 facing the second deflector plate 32. The second boss 42 is inclined relative to the side surface of the second deflector plate 32, such that the width of the first end of the second boss 42 is greater than the width of the second end. Thus, the first end of the second boss 42 constitutes a second pushing portion 421, and the second end of the second boss 42 constitutes a second yielding portion 422. When the user moves the adjustment portion 40 to the first position, the first end of the second boss 42 moves to the position corresponding to the second deflector plate 32 to push the second deflector plate. When the user moves the adjustment portion 40 to the second position, the second end of the second boss 42 moves to the position corresponding to the second deflector plate 32 to yield to the second deflector plate 32.

[0058] In some embodiments, an annular mounting groove is provided on the inner wall surface of the housing 20 ; the adjusting portion 40 is installed in the mounting groove and can rotate along the mounting groove between a first position and a second position.

[0059] Specifically, the adjusting portion 40 is movably mounted on the mounting slot so that the adjusting portion 40 can move between the first position and the second position. This arrangement can achieve guidance of the adjusting portion 40 without adding other guide members, making it more convenient for users to operate.

[0060] like Figures 2 to 6 As shown, in some embodiments, the adjusting portion 40 is configured as an annular structure corresponding to the mounting groove, and a rotating protrusion 43 is further provided at one end of the adjusting portion 40 away from the water pipe 11 .

[0061] Specifically, the annular adjustment portion 40 is mounted within the mounting slot and is rotatable between a first position and a second position. A first pusher 411 and a first relief portion 412 are provided on the inner sidewall of the annular adjustment portion 40 at positions corresponding to the first deflector plate 31. A second pusher 421 and a second relief portion 422 are provided on the inner sidewall of the adjustment portion 40 at positions corresponding to the second deflector plate 32. When a user rotates the adjustment portion 40, the first pusher 411, the first relief portion 412, the second pusher 421, and the second relief portion 422 are simultaneously driven to move, thereby simultaneously driving the first deflector plate 31 and the second deflector plate 32 to move.

[0062] At the same time, a rotating protrusion 43 is provided at one end of the regulating portion 40 away from the water pipe 11 , and the user can rotate the regulating portion 40 through the rotating protrusion 43 , which is more convenient for the user to operate.

[0063] like Figure 3As shown, in some embodiments, the first guide plate 31 includes a first inclined portion 311, and the first inclined portion 311 is inclined at one end away from the water pipe 11 and is arranged toward the second guide plate 32; the second guide plate 32 includes a second inclined portion 321, and the second inclined portion 321 is inclined at both ends away from the water pipe 11 and is arranged toward the second guide plate.

[0064] Specifically, the first deflector 31 also includes a first straight portion. The first end of the first inclined portion 311 is connected to the side of the first straight portion facing away from the water pipe 11, and the second end of the first inclined portion 311 extends obliquely along the direction of water flow toward the second deflector 32. Similarly, the second deflector 32 also includes a second straight portion. The first end of the second inclined portion 321 is connected to the side of the second straight portion facing away from the water pipe 11, and the second end of the second inclined portion 321 extends obliquely along the direction of water flow toward the first deflector 31.

[0065] With this arrangement, the water flow can impact the first inclined portion 311 of the first guide plate 31 and the second inclined portion 321 of the second guide plate 32 , so as to prevent the water flow from failing to push the first guide plate 31 and the second guide plate 32 .

[0066] In some embodiments, a limiting portion is provided at a position corresponding to the shell 20 and the adjusting portion 40; a rear limiting matching portion is provided corresponding to the adjusting portion 40 and the limiting portion; after the adjusting portion 40 moves to the first position or the second position, the limiting portion limits the limiting matching portion to prevent the adjusting portion 40 from continuing to rotate.

[0067] Specifically, a limiting protrusion is provided at a position on the housing 20 corresponding to the adjustment portion 40, and a limiting slot is provided at a position on the adjustment portion 40 corresponding to the limiting protrusion. The limiting protrusion is at least partially disposed within the limiting slot, and the limiting slot guides the limiting protrusion in a direction consistent with the direction of movement of the adjustment portion 40. Thus, after the adjustment portion 40 moves to the first position, the limiting protrusion can abut one end of the limiting slot; alternatively, after the adjustment portion 40 moves to the second position, the limiting protrusion can abut the other end of the limiting slot. With this arrangement, the limiting portion prevents the adjustment portion 40 from further movement after it moves to either the first or second position.

[0068] In some embodiments, the shower head 12 further includes an elastic element having a first end and a second end connected to the first guide plate 31 and the second guide plate 32 respectively; wherein the elastic element can push the first guide plate 31 away from the second guide plate 32.

[0069] Specifically, the elastic element is disposed between the first guide plate 31 and the second guide plate 32, with both ends of the elastic element connected to the first guide plate 31 and the second guide plate 32. Thus, when the water flow is too low to push the first guide plate 31 or the second guide plate 32, the elastic element can replace the water flow to push the first guide plate 31 and the second guide plate 32.

[0070] like Figure 1 As shown, the embodiment of the present disclosure further provides a dishwasher comprising: a water pipe 11 and the above-mentioned shower head 12 for the dishwasher. The water pipe 11 is used to supply water; wherein the water pipe 11 is connected to the flow channel of the shower head 12 to supply water to the flow channel.

[0071] Specifically, the dishwasher further includes a housing 20, which is provided with a cleaning chamber. The shower head 12 is disposed within the cleaning chamber, and a water pipe 11 is connected to the shower head 12. The water pipe 11 can supply water to the shower head 12, and the water is sprayed into the cleaning chamber through the shower head 12.

[0072] A dishwasher using the shower head 12 for a dishwasher provided in this application can adjust the gap between the first guide plate 31 and the second guide plate 32 through the adjustment part 40 to control the area and pressure of the water flow sprayed from the shower head 12, making the functions more diversified and the user experience better.
