[0052] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] like Figures 1 to 12 As shown, this embodiment provides a dishwasher spray device, which includes a spray assembly 1 and a reflective diverter 2. The spray assembly 1 can spray fluid toward the reflective diverter 2, and the formed spray fluid is refracted and / or reflected by the reflective diverter 2 to rinse the tableware.

[0056] The reflective diverter 2 can be located above the injection component 1, and the injection component 1 sprays the fluid upward to the reflective diverter 2. The fluid forms a high initial velocity under the injection action and overcomes the gravity to perform a deceleration motion. The fluid can be liquids such as water or cleaning liquid. After the sprayed fluid is refracted and / or reflected by the reflective diverter 2, it spreads out like a fountain under the action of gravity to rinse the tableware. For example, it can be used as a compensatory cleaning means to clean the surface of the tableware, thereby enhancing the tableware cleaning effect, avoiding secondary cleaning of the tableware, and improving the tableware cleaning efficiency, breaking through the existing conventional cleaning methods, and improving the user experience.

[0057] In some embodiments, the reflective diverter 2 can rotate under the driving action of the jet fluid. The impact force of the jet fluid drives the reflective diverter 2 to rotate. The reflective diverter 2 can be a rotating body structure, rotating around its own axis. During the rotation of the reflective diverter 2, centrifugal force is generated, which removes the impact force of the jet fluid while maintaining stable rotation. During the rotation of the reflective diverter 2, the jet fluid spreads like a fountain under the action of gravity to rinse the tableware. The reflective diverter 2 can be an inverted bowl-shaped structure, and the bowl mouth of the reflective diverter 2 faces the jet fluid. The reflective diverter 2 can also be a shuttle-shaped structure, and the shuttle tip of the reflective diverter 2 faces the jet fluid.

[0058] Optionally, a plurality of spiral blades 21 are provided on the surface of the reflective diverter 2, and the jet fluid can push the spiral blades 21 to drive the reflective diverter 2 to rotate. The impact force of the jet fluid acts on the spiral blades 21, and the spiral structure of the spiral blades 21 removes the impact force of the jet fluid, and at the same time forms a driving force for the reflective diverter 2 to promote the rotation of the reflective diverter 2. The plurality of spiral blades 21 can ensure that the rotation of the reflective diverter 2 is relatively stable. Under the guidance of the spiral structure of the spiral blades 21, the jet fluid whose impact force is removed still has a relatively fast speed, and under the action of gravity, it spreads like a fountain to rinse the tableware. The spiral blades 21 can be installed on the reflective diverter 2 by fasteners such as bolts, which is convenient for disassembly, maintenance and replacement. The spiral blades 21 can also be integrally formed with the reflective diverter 2 to facilitate batch production.

[0059] In order to ensure that the reflective diverter 2 is evenly stressed and rotates smoothly, the multiple spiral blades 21 are optionally distributed in a centrally symmetrical manner. The reflective diverter 2 can be a rotating body structure, and the intersection point of the rotation axis of the reflective diverter 2 and the surface of the reflective diverter 2 is the symmetry center of the multiple spiral blades 21. The multiple spiral blades 21 can be arranged in one layer, or in two or more layers with the rotation axis of the reflective diverter 2 as the axial direction. The multiple layers of spiral blades 21 are conducive to the spray fluid to be spread more widely to rinse tableware in different areas.

[0060] Optionally, the reflective diverter 2 is mounted on the top of the inner cavity 3 of the dishwasher via a rotating shaft. When the dishwasher is a drawer-type dishwasher, since the inner cavity 3 of the drawer-type dishwasher includes a drawer-like structure and a top cover plate, the top cover plate is fixed, and the drawer-like structure can be pulled out for users to take and put tableware, the reflective diverter 2 can be mounted on the top cover plate of the dishwasher via a rotating shaft.

[0061] Optionally, the reflective diverter 2 has a diverter camber. After the jet fluid is refracted and / or reflected by the diverter camber of the reflective diverter 2, it spreads out like a fountain under the action of gravity to wash the tableware. The diverter camber adopts a camber structure, which can avoid the flow velocity loss of the jet fluid to the greatest extent and reduce the impact force of the jet fluid on the reflective diverter 2. In addition, compared with other irregular curved surfaces, the camber structure is easier to process and shape, thereby reducing the manufacturing and processing costs.

[0062] In some embodiments, the curvature radius of the diverter arc surface is adjustable. After being refracted and / or reflected by the diverter arc surface, the jetted fluid is dispersed like a fountain under the action of gravity to rinse the tableware. By adjusting the curvature radius of the diverter arc surface, the degree of refraction and / or reflection of the jetted fluid by the diverter arc surface is changed, so that the tableware in different areas can be rinsed, which improves the tableware cleaning efficiency and the tableware cleaning effect, breaks through the existing conventional cleaning method, and improves the user experience.

[0063] Optionally, the reflective diverter 2 includes an umbrella face, an umbrella frame and an umbrella pole, the center of the umbrella face is connected to the umbrella pole, the edge of the umbrella face is connected to the umbrella frame, and the umbrella frame is slidably connected to the umbrella pole. The reflective diverter 2 can use the umbrella holding principle to adjust the radius of curvature. The umbrella frame slides relative to the umbrella pole to open the umbrella face. The outer surface of the umbrella face is the diverter arc surface. The degree of opening of the umbrella face corresponds to the radius of curvature of the diverter arc surface on the outer surface of the umbrella face. By adjusting the degree of opening of the umbrella face, the refraction and / or reflection degree of the jet fluid through the diverter arc surface on the outer surface of the umbrella face is changed, so that tableware in different areas can be rinsed, the tableware cleaning efficiency is improved, the tableware cleaning effect is enhanced, the existing conventional cleaning method is broken through, and the user experience is improved. The sliding of the umbrella frame relative to the umbrella pole can be automatically toggled by a driving member such as a motor, or it can be manually toggled, depending on the application scenario.

[0064] In some embodiments, the reflective diverter 2 is provided with a guide rib. By guiding the injection fluid through the guide rib, the impact force of the injection fluid on the reflective diverter 2 can be reduced. The guide rib can be a spiral structure to improve the diversion effect. A plurality of guide ribs can be provided, and the plurality of guide ribs can be distributed in a central symmetrical manner.

[0065] Optionally, the guide rib is provided with a guide hole. The jet fluid can pass through the guide hole, reducing the impact force of the jet fluid on the guide rib. The guide hole can be circular, elliptical, square, triangular, etc., which are not limited here. A plurality of guide holes can be provided, and the plurality of guide holes are arranged along the extension direction of the guide rib.

[0066] In some embodiments, the distance between the reflective diverter 2 and the spray assembly 1 is adjustable. By adjusting the distance between the reflective diverter 2 and the spray assembly 1, the degree of refraction and / or reflection of the spray fluid by the reflective diverter 2 is changed, so that the tableware in different areas can be rinsed, the tableware cleaning efficiency is improved, the tableware cleaning effect is enhanced, the existing conventional cleaning method is broken, and the user experience is improved.

[0067] Optionally, the reflective diverter 2 is installed on the top of the inner cavity 3 of the dishwasher through a telescopic rod with adjustable length. The telescopic rod includes a first rod and a second rod that are slidably connected. The second rod can be a hollow rod, which is sleeved on the outside of the first rod. The relative sliding of the first rod and the second rod changes the overall length of the first rod and the second rod. The telescopic rod with adjustable length can be automatically driven by a driving member such as a cylinder, or it can be adjusted by manual gear. When the dishwasher is a drawer-type dishwasher, since the inner cavity 3 of the drawer-type dishwasher includes a drawer-like structure and a top cover plate, the top cover plate is fixed, and the drawer-like structure can be pulled out for users to take and put tableware, the reflective diverter 2 can be installed on the top cover plate of the dishwasher through the telescopic rod with adjustable length.

[0068] In some embodiments, the reflective diverter 2 includes a first diverter and a second diverter that can rotate relative to each other, and the first diverter and the second diverter can respectively divert the jet fluid to rinse the tableware in different areas. One of the first diverter and the second diverter can be stationary and the other can rotate. Of course, both the first diverter and the second diverter can rotate, but the rotation of the first diverter and the second diverter has a speed difference, so that the jet fluid is reflected and / or refracted to different degrees, so that the tableware in different areas can be rinsed, which improves the efficiency of tableware cleaning, enhances the tableware cleaning effect, breaks through the existing conventional cleaning method, and improves the user experience.

[0069] Optionally, the first diverter is mounted on the top of the inner cavity 3 of the dishwasher via a mounting shaft, and the second diverter is rotatably connected to the mounting shaft. Since the first diverter is fixed when the jet fluid is sprayed on the first diverter, the second diverter can rotate around the mounting shaft, so that the first diverter and the second diverter reflect and / or refract the jet fluid to different degrees, thereby washing tableware in different areas. When the dishwasher is a drawer-type dishwasher, since the inner cavity 3 of the drawer-type dishwasher includes a drawer-like structure and a top cover plate, the top cover plate is fixed, and the drawer-like structure can be pulled out for users to take and put tableware, the first diverter can be mounted on the top cover plate of the dishwasher via the mounting shaft.

[0070] In some embodiments, the spray assembly 1 includes a pressure pump and a water collecting structure. The pressure pump is used to pressurize the fluid and convey it to the water collecting structure. The water collecting structure can spray the fluid toward the reflective diverter 2. By pressurizing the fluid with the pressure pump, the velocity of the fluid sprayed by the water collecting structure can be increased, ensuring that the sprayed fluid can reach the reflective diverter 2 and disperse under the reflection and / or refraction of the reflective diverter 2 to rinse the tableware. The water collecting structure may include a main waterway 11 and a plurality of diverter channels 12. The plurality of diverter channels 12 may converge in a spiral shape on the main waterway 11 to increase the velocity of the fluid sprayed from the main waterway 11. The tops of the diverter channels 12 converge on the main waterway 11, and the bottoms of the diverter channels 12 are connected to the base 13. The base 13 is conveniently connected to the inner tank body 1. The water collecting structure may adopt a rotating cylindrical structure whose cross section gradually decreases from bottom to top, so that the velocity of the fluid sprayed from the water collecting structure is relatively large. For example, the water collecting structure may be in the shape of a vase (such as Fig. 9 as shown) or cone-shaped (as Fig.11 and 12 shown).

[0071] Optionally, the water collecting structure is provided with a main outlet 14 and a branch outlet, the main outlet 14 forms a jet of water to the reflective diverter 2, and the branch outlet is used to supply liquid to other spray devices. When the water collecting structure is a cylindrical structure, the main outlet 14 can be an upper opening of the cylindrical structure, and the branch outlet can be arranged on the side wall of the cylindrical structure. Other spray devices specifically refer to spray devices used for spraying tableware in the dishwasher, such as spray holes or nozzles on the spray pipeline. With the mutual compensation and cooperation between the dishwasher spray device of this embodiment and other spray devices, the tableware can be cleaned in all directions, the tableware cleaning effect is enhanced, the secondary cleaning of the tableware is avoided, and the tableware cleaning efficiency is improved.

[0072] This embodiment also provides a dishwasher spraying method, which uses the above-mentioned dishwasher spraying device to rinse tableware, including the following steps:

[0073] The spray assembly 1 sprays fluid toward the reflective diverter 2;

[0074] The reflective flow divider 2 refracts and / or reflects the fluid sprayed by the spray assembly 1 to rinse the dishes;

[0075] The degree of refraction and / or reflection of the fluid by the reflective diverter 2 is adjusted to rinse dishes in different areas.

[0076] After being refracted and / or reflected by the reflective diverter 2, the jet fluid spreads out like a fountain under the action of gravity to rinse the tableware. After changing the degree of refraction and / or reflection of the fluid by the reflective diverter 2, the tableware in different areas can be rinsed, thereby enhancing the tableware cleaning effect, avoiding secondary cleaning of the tableware, improving the tableware cleaning efficiency, breaking through the existing conventional cleaning methods, and improving the user experience.

[0077] In some embodiments, the rotation speed of the reflective diverter 2 is adjusted to rinse tableware in different areas. When the rotation speed of the reflective diverter 2 is relatively low, the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is relatively small, so that tableware that is relatively close can be sprayed. When the rotation speed of the reflective diverter 2 is relatively high, the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is relatively large, so that tableware that is relatively far can be sprayed. The rotation speed of the reflective diverter 2 can be adjusted by actively providing a driving force to the reflective diverter 2 through a motor to intervene and adjust the rotation speed of the reflective diverter 2, or the rotation speed of the reflective diverter 2 can be adjusted in a passive manner, such as by adjusting the rotational damping of the reflective diverter 2.

[0078] Optionally, the radius of curvature of the diverter arc surface of the reflective diverter 2 is adjusted to rinse tableware in different areas. When the radius of curvature of the diverter arc surface of the reflective diverter 2 is small, the curvature of the reflective diverter 2 is large, and the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is large, so that it can be sprayed to tableware at a distance. When the radius of curvature of the diverter arc surface of the reflective diverter 2 is large, the curvature of the reflective diverter 2 is small, and the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is small, so that it can be sprayed to tableware at a distance. Adjusting the radius of curvature of the diverter arc surface changes the degree of refraction and / or reflection of the jet fluid by the diverter arc surface, so that tableware in different areas can be rinsed, thereby improving the efficiency of tableware cleaning, enhancing the effect of tableware cleaning, breaking through the existing conventional cleaning methods, and improving the user experience.

[0079] In some embodiments, the distance between the reflective diverter 2 and the injection assembly 1 is adjusted to rinse tableware in different areas. When the distance between the reflective diverter 2 and the injection assembly 1 is small, the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is large, so that tableware at a farther distance can be sprayed. When the distance between the reflective diverter 2 and the injection assembly 1 is large, the radius of the rinsing area formed after the jet fluid is refracted and / or reflected by the reflective diverter 2 is small, so that tableware at a closer distance can be sprayed. By adjusting the distance between the reflective diverter 2 and the injection assembly 1, the degree of refraction and / or reflection of the jet fluid by the reflective diverter 2 is changed, so that tableware in different areas can be rinsed, thereby improving the efficiency of tableware cleaning, enhancing the tableware cleaning effect, breaking through the existing conventional cleaning methods, and improving the user experience.

[0080] Optionally, the flow rate of the fluid sprayed by the spray component 1 is adjusted to rinse tableware in different areas. When the flow rate of the fluid sprayed by the spray component 1 is relatively low, the radius of the rinsing area formed after the sprayed fluid is refracted and / or reflected by the reflective diverter 2 is relatively small, so that tableware that is relatively close can be sprayed. When the flow rate of the fluid sprayed by the spray component 1 is relatively high, the radius of the rinsing area formed after the sprayed fluid is refracted and / or reflected by the reflective diverter 2 is relatively large, so that tableware that is relatively far can be sprayed. By adjusting the flow rate of the fluid sprayed by the spray component 1, the degree of refraction and / or reflection of the sprayed fluid by the reflective diverter 2 is changed, so that tableware in different areas can be rinsed, thereby improving the efficiency of tableware cleaning, enhancing the tableware cleaning effect, breaking through the existing conventional cleaning methods, and improving the user experience.

[0081] The present embodiment also provides a dishwasher, which can be a drawer-type dishwasher or other types of dishwashers, which are not limited here. The dishwasher includes a shell and the above-mentioned dishwasher spray device, and the dishwasher spray device is arranged in the shell. The reflective diverter 2 can be located above the injection assembly 1, and the injection assembly 1 sprays the fluid upward to the reflective diverter 2. The fluid forms a higher initial velocity under the action of the injection and overcomes the gravity to perform a deceleration motion. The fluid can be a liquid such as water or a cleaning liquid. After the injection fluid is refracted and / or reflected by the reflective diverter 2, it spreads out like a fountain under the action of gravity to rinse the tableware. For example, it can be used as a compensatory cleaning means to clean the surface of the tableware, thereby enhancing the tableware cleaning effect, avoiding secondary cleaning of the tableware, and improving the tableware cleaning efficiency. It breaks through the existing conventional cleaning methods and enhances the user experience.

[0082] Optionally, the dishwasher also includes a rack for holding tableware, the rack is provided with an avoidance gap, the avoidance gap is used to avoid the fluid sprayed by the injection assembly 1, so as to avoid interference between the rack and the injected fluid. The injection fluid is avoided in the form of the avoidance gap, and only an opening needs to be made on the original rack, and the modification cost is low.

[0083] To facilitate the collection of the fluid that has been rinsed with the dishes, the dishwasher may optionally further include a water collecting tray 4, which is used to receive the fluid that has been rinsed with the dishes. The water collecting tray 4 may be located at the bottom of the inner body of the dishwasher, and the water collecting tray 4 may adopt a concave structure to facilitate the collection of the fluid to the water outlet at the bottom of the water collecting tray 4. To improve the utilization rate of water resources, the dishwasher may optionally further include a return pipe, and the water collecting tray 4 is connected to the water storage tank through the return pipe. The water in the water storage tank may be pressurized by a booster pump and then transported to the water collecting structure, or may be used by other spraying devices. To facilitate filtering impurities in the water in the water collecting tray 4, a filter screen 5 may be optionally provided between the water collecting tray 4 and the return pipe. By filtering out impurities in the water through the filter screen 5, the water may be reused for spraying again, thereby saving water resources and eliminating the need for the user to repeatedly add water, thereby improving the user experience.
