Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a spray tray device and cleaning equipment. Background Technology

[0002] The spray arm is an important component of cleaning equipment such as dishwashers. High-pressure fluid supplied by a water pump is accelerated through the jet holes on the spray arm to form a high-speed jet that rinses the surface of the dishes to remove stains. In existing technologies, spray arm assemblies typically have two or three arms. To achieve higher pressure and jet velocity, only a limited number of jet holes can be installed on the spray arm. Independent spray arms result in significant hydraulic losses within the flow channel, reducing water pressure and jet velocity at the nozzles. Furthermore, the jet holes are often vertically upward and predominantly circular or elongated. Therefore, the direct impact range and angle of the cleaning liquid sprayed from the spray arm are limited. During spraying, other areas are indirectly cleaned only through splashing between dishes, easily creating blind spots and resulting in poor cleaning effectiveness.

[0003] To improve cleaning effectiveness, existing technologies have proposed a 360° spray arm that sprays water in a fan shape through fan-shaped slits on the nozzle, sweeping across the entire inner wall and corners of the container. The rotating water jets repeatedly clean the container, improving cleanliness and efficiency. However, this device has a complex nozzle structure, making manufacturing difficult, and the thin fan-shaped slits are prone to clogging. Another existing technology proposes a dishwasher spray structure where the spray arm can simultaneously rotate and revolve, operating on two combined motion trajectories. This increases the cleaning area and spray angle, more effectively cleaning dishes and avoiding blind spots. However, the transmission trajectory has two eccentric rotating shafts, increasing the instability of the spray structure. Furthermore, this device significantly increases the thickness of the spray tray, further reducing the effective volume of the cleaning device.

[0004] Therefore, there is an urgent need to develop a spray tray device and cleaning equipment with high cleaning efficiency and effectiveness to solve the above-mentioned technical problems. Summary of the Invention

[0083] Implementation Method 1

[0084] This embodiment provides a spray tray device, such as Figure 1 As shown, the spray disc device includes a base plate 1, a perforated disc 2, and a top plate 3 connected sequentially from bottom to top. All three plates are disc-shaped, and their central axes of rotation are on the same straight line. The base plate 1 and the perforated disc 2 are fixedly connected, forming a pressure water storage chamber of a certain depth between them. The perforated disc 2 and the top plate 3 are movably connected, specifically a rotatable connection, meaning the top plate 3 can rotate around its central axis relative to the rigid connection formed by the base plate 1 and the perforated disc 2.

[0085] like Figure 2 and Figure 3 As shown. The chassis 1 is equipped with a cleaning fluid inlet communicating with the aforementioned water storage chamber, used to introduce cleaning fluid into the water storage chamber. The perforated disc 2 is provided with multiple jetting holes 211, which communicate with the water storage chamber. These multiple jetting holes 211 are distributed at different radii on the perforated disc 2, and have different inclination angles and / or different cross-sectional areas and / or different orifice shapes to meet different jetting requirements. The top disc 3 is configured to selectively connect with some of the jetting holes 211 on the perforated disc 2, allowing cleaning fluid to be sprayed into the dishwasher's inner drum for cleaning. Different jet orifices 211 can achieve different jet effects. By changing the angle between the normal direction of the jet orifice 211 and the plate surface, jet patterns with different incident angles can be obtained. By changing the cross-sectional area of ​​the jet orifice 211, jets with different flow velocities can be obtained, thereby changing the impact force of the jet on the dishes. By changing the shape of the orifice, the diffusion state after the jet exits can be changed, thereby achieving different degrees of water immersion on the dishes. By changing the radial distribution of the jet orifice 211 on the porous plate 2, the size of the cleaning area of ​​the jet can be changed.

[0086] The spray plate device provided in this embodiment rotates the top plate 3 relative to the perforated plate 2 to change the communication state of the jet flow holes 211 on the perforated plate 2. Since the jet flow holes 211 on the perforated plate 2 have different inclination angles and / or different cross-sectional areas and / or different orifice shapes, the number, position, inclination angle, and cross-sectional shape of the connected jet flow holes 211 change with the rotation of the top plate 3. This alters the cleaning range, cleaning intensity, and cleaning angle of the jet, reducing dead zones in the jet cleaning process and ensuring sufficient pressure in the water storage chamber inside the spray plate device. By integrating multiple different types of jet flow holes 211, this spray plate device can achieve the multi-spray arm time-sharing scheme found in existing technologies, enabling multi-area, multi-angle, and multi-intensity jet cleaning, avoiding dead zones, and significantly improving the cleanliness and efficiency of the container. Compared to the spray arm structure in existing technologies, the disc-shaped structure increases the flow area of ​​the cleaning liquid, reduces the flow velocity of the cleaning liquid in the spray plate device, and significantly reduces flow resistance, thereby reducing hydraulic losses.

[0087] Furthermore, the cross-sectional shape of the internal flow channel of the jet orifice 211 varies. Specifically, the cross-sectional shape of the internal flow channel of the jet orifice 211 includes a constant cross-section type, a contraction type, and a scaling type. When the internal flow channel of the jet orifice 211 is a contraction type, the jet flow has high concentration, the jet is not easy to diffuse, and its impact force is strong; when the internal flow channel of the jet orifice 211 is a scaling type, when the fluid passes through the minimum cross-section, the pressure reduction causes dissolved air in the water to precipitate, forming a microbubble jet, which has a beneficial effect on cleaning.

[0088] In this embodiment, such as Figure 2 As shown, the chassis 1 includes a first disc body 11, an inlet pipe 12, and a first sealing buckle 13. The first disc body 11 has a cleaning fluid inlet at its center. The inlet pipe 12 connects to the cleaning fluid inlet and is smoothly curved to the first disc body 11 to reduce water flow resistance. The first sealing buckle 13 is located on the upper surface of the first disc body 11 near its edge and is sealed to the porous disc 2 to form a water storage cavity of a certain depth. Optionally, the first sealing buckle 13 is an annular protrusion protruding from the upper surface of the first disc body 11.

[0089] Optionally, the cross-sectional area of ​​the inlet pipe 12 gradually decreases from the end where the cleaning liquid inlet is located to the end furthest from the cleaning liquid inlet, meaning that the diameter of the inlet pipe 12 is largest at the connection point with the cleaning liquid inlet. This structural arrangement allows for a gradual increase in the flow rate entering the water storage chamber.

[0090] Optionally, a plurality of nozzles 111 are provided on the first disc 11 near the first sealing buckle 13. The internal flow channel of the nozzle 111 has a vertically downward component and a radially inward component along the first disc 11. This allows the jet formed by the nozzle 111 to flush the stains adhering to the countertop into the water tank. Preferably, the edges of the nozzles 111 are rounded with the disc surface to reduce hydraulic loss.

[0091] Optionally, the first plate 11 is also provided with a slag discharge groove 112, which is conducive to discharging the residue from the slag discharge groove 112 into the bottom surface of the inner liner.

[0092] refer to Figures 3 to 7 As shown, in this embodiment, the perforated disk 2 includes a second disk body 21. The second disk body 21 has a plurality of radially arranged jetting holes 211. A flow-rectifying flange 212 is provided on the lower surface of the second disk body 21, directly opposite the cleaning fluid inlet. The flow-rectifying flange 212 can disperse the incoming flow impact at the inlet pipe 12 and reduce hydraulic loss. Since the cleaning fluid inlet is located at the center of the first disk body 11, the flow-rectifying flange 212 is also located at the center of the second disk body 21.

[0093] Optionally, the perforated disc 2 further includes a second sealing buckle 22, which is disposed on the lower surface of the second disc body 21. The second sealing buckle 22 is sealed and engaged with the first sealing buckle 13. The first disc body 11, the first sealing buckle 13, the second sealing buckle 22, and the second disc body 21 together form a water storage cavity with a certain depth. Optionally, the second sealing buckle 22 is an annular protrusion protruding from the lower surface of the second disc body 21.

[0094] Furthermore, the second plate 21 is also provided with a slag discharge hole 213, which is connected and sealed to the slag discharge groove 112 on the first plate 11. The slag discharge hole 213 and the slag discharge groove 112 form a channel that allows food residue to be discharged to the bottom of the inner liner. The two are sealed to ensure that the liquid in the water storage cavity will not leak out, thereby ensuring the pressure of the water storage cavity.

[0095] like Figure 8 and Figure 9 As shown, in this embodiment, the top plate 3 includes a third plate body 31 and a rotating through hole 32 formed on the third plate body 31. The third plate body 31 is rotatably connected to the second plate body 21, and the rotating through hole 32 is configured to selectively communicate with some of the injection holes 211 on the second plate body 21. During the rotation of the third plate body 31 relative to the second plate body 21, the relative position of the rotating through hole 32 and the second plate body 21 changes, thereby enabling communication between the injection holes 211 in different areas of the second plate body 21.

[0096] Optionally, multiple second through holes are provided, and the multiple second through holes are arranged symmetrically about the center of the third disk 31. For example, there are three second through holes in this embodiment, and the specific number can be determined according to actual needs. Preferably, the second through hole is a strip-shaped hole so as to connect more jet through holes 211. Of course, the shape of the second through hole is not limited to this. As long as it extends radially from near the center to near the edge along the third disk 31 and has a certain area, it can connect a certain number of jet through holes 211 at the same time. For example, it can also be a fan-shaped hole or a narrow fan-shaped hole.

[0097] Furthermore, combined Figure 4 and Figure 9 As shown, one of the outer peripheral surfaces of the third disc 31 and the second disc 21 is provided with an annular flange 214, and the other is provided with an annular groove 33. The annular flange 214 and the annular groove 33 are engaged. This structure not only achieves axial positioning of the top disc 3 and the perforated disc 2, but also keeps the remaining jet through holes 211 that are not connected to the rotating through hole 32 blocked.

[0098] Preferably, the outer surface of the third disc 31 is an inclined plane with a higher center and a lower outer surface, or a curved surface with an upward convex center. This structure facilitates the flow of food residue and water from the rinsing surface outward to the bottom surface of the inner liner and its collection. Note that the outer surface referred to here is the side of the third disc 31 that faces away from the second disc 21.

[0099] More preferably, a ring of protrusions is provided around the outer side of the rotating through hole 32 to prevent water flow from the disc surface from flowing into the strip hole and thus affecting the jetting effect.

[0100] In this embodiment, multiple rotating through holes 32 are provided to meet the quantity requirements of the connecting jet through holes 211. Preferably, the multiple rotating through holes 32 are centrally symmetrical about the center of the third disc 31. This arrangement can achieve uniform liquid discharge and improve the cleaning effect. In this embodiment, the third disc 31 is provided with three rotating through holes 32. The specific number of rotating through holes 32 can be selected according to actual needs. They will not be listed here.

[0101] In this embodiment, the spray disc device further includes a power mechanism 4, which includes a first drive assembly and a transmission mechanism. The first drive assembly is driven and connected to the chassis 1 to drive the chassis 1 to rotate. The transmission mechanism is disposed between the perforated disc 2 and the top disc 3, and is configured to drive the top disc 3 to rotate relative to the perforated disc 2. Since the perforated disc 2 and the chassis 1 are fixedly connected, the perforated disc 2 rotates synchronously relative to the chassis 1 under the driving action of the first drive assembly. Since the top disc 3 and the perforated disc 2 are rotatably connected, the transmission mechanism can drive the top disc 3 to rotate relative to the perforated disc 2, thereby changing the connectivity of the jet flow holes 211 on the perforated disc 2.

[0102] Specifically, such as Figure 11 As shown, the first drive assembly includes a first motor 41 and a first power gear 42. The first power gear 42 is connected to the output end of the first motor 41. A gear portion 14 is provided on the outer peripheral surface of the chassis 1, i.e., the outer peripheral surface of the first disc body 11, and the first power gear 42 meshes with the gear portion 14. The first motor 41 drives the first power gear 42 to rotate, and the first power gear 42 drives the chassis 1, which meshes with it, to rotate, thereby realizing the driving effect of the first drive assembly on the chassis 1. Optionally, the first motor 41 is located at the bottom of a cleaning device such as a dishwasher and is separated from the water channel. The first motor 41 can rotate in both forward and reverse directions to meet different usage requirements.

[0103] Optionally, such as Figure 10 As shown, the transmission mechanism is a ratchet mechanism, which includes a spring seat 23, a pawl 24, and a ratchet groove 34 on the top plate 3, all mounted on the perforated disk 2. The pawl 24 provides rotational power to the top plate 3. This ratchet structure is a conventional existing technology, and its working principle will not be described in detail here. When the first motor 41 rotates clockwise, the first power gear 42 and the ratchet mechanism drive the entire spray disk device to rotate clockwise. When the first motor 41 stops or reverses instantaneously, the perforated disk 2 stops or reverses, while the top plate 3 continues to rotate clockwise due to inertia. At this time, the top plate 3 and the perforated disk 2 rotate relative to each other, and the communication state between the rotating through hole 32 of the top plate 3 and the jet through hole 211 on the perforated disk 2 changes.

[0104] Preferably, a first connecting buckle 25 is provided at the center of the upper surface of the second disc 21, and a second connecting buckle 35 is provided at the center of the ratchet groove 34. The first connecting buckle 25 and the second connecting buckle 35 are rotatably connected. The specific structure of the two connecting buckles is not the focus of protection of this invention; any existing structure that can achieve the rotatable connection between the two is acceptable.

[0105] Compared with the prior art, this embodiment provides a disc-shaped spray plate device. The cleaning liquid enters the water storage cavity formed inside the spray plate device through the liquid inlet pipe 12. Due to the selective passage restriction of the rotating through hole 32 of the top plate 3, only a small number of jet through holes 211 can form a jet. When the program controls the first motor 41 to rotate forward at a certain speed to drive the first power gear 42 to rotate, the power is transmitted to the spray plate device through the gear connection. The entire spray plate rotates clockwise and makes the jet form a circular motion, increasing the cleaning range of the jet. After the spray disc rotates a certain number of times, the number of rotations and time of the first power gear 42 can be calculated through the transmission ratio. At this time, the first motor 41 is briefly stopped or reversed. Since the perforated disc 2 is rigidly connected to the chassis 1, the perforated disc 2 will also stop or reverse. The top disc 3 and the perforated disc 2 have relative motion. Due to inertia, the top disc 3 continues to move clockwise. At this time, the ratchet mechanism undergoes relative rotational displacement, and the rotating through-hole 32 will rotate to a new position relative to the perforated disc 2. Since the state of the jet flow hole 211 connected to the rotating through-hole 32 changes, the formed jet will also change accordingly. At this time, the program controls the first motor 41 to rotate forward at the original speed again, so that the jet forms a circular motion again. Following this process, by changing the phase angle between the top disc 3 and the perforated disc 2, the number, inclination angle, position, cross-sectional shape, and other factors of the jet flow hole 211 connected to the rotating through-hole 32 can be changed, thereby correspondingly changing the cleaning range, cleaning force, and cleaning angle of the jet. By integrating various types of jet orifices 211, a time-sharing solution for multiple spray arms can be achieved. Multiple spray arms are integrated into one spray plate to realize multi-area, multi-angle, and multi-intensity jet cleaning, thereby improving the cleanliness and cleaning efficiency of the container.

[0106] This embodiment also provides a cleaning device, including an inner tank and the above-mentioned spray plate device. Since the spray plate device can realize multi-area, multi-angle, and multi-intensity jet cleaning, the cleaning degree and cleaning efficiency of the cleaning device are significantly improved.

[0107] Implementation Method 2

[0108] This embodiment provides a spray disc device, which is basically the same as the spray disc device in Embodiment 1 above, except that the form in which the perforated disc 2 and the top disc 3 are driven to rotate relative to each other is different.

[0109] Specifically, the power mechanism 4 includes a first drive assembly and a second drive assembly. The first drive assembly is connected to the chassis 1 to drive the chassis 1 to rotate, and the second drive assembly is connected to the top plate 3 to drive the top plate 3 to rotate. By using two sets of drive assemblies to drive the chassis 1 and the top plate 3 to rotate respectively, the relative rotation and phase angle switching between the top plate 3 and the perforated disk 2 can be achieved.

[0110] Furthermore, such as Figure 12 and Figure 13 As shown, the first drive assembly includes a first motor 41 and a first power gear 42. The first power gear 42 is connected to the output end of the first motor 41. A gear portion 14 is provided on the outer peripheral surface of the chassis 1, and the first power gear 42 meshes with the gear portion 14. The second drive assembly includes a second motor 43 and a second power gear 44. The second power gear 44 is connected to the output end of the second motor 43. A second gear portion 36 is provided on the outer peripheral surface of the top plate 3, and the second power gear 44 meshes with the second gear portion 36.

[0111] When the two motors are controlled to rotate at the same speed through a program, the entire spray disc device can maintain the same angular velocity, and the discs remain relatively stationary. When it is necessary to switch the phase angle between the perforated disc 2 and the top disc 3, the two motors can be used to drive the perforated disc 2 and the top disc 3 to rotate relative to each other, thereby connecting the jet orifices 211 at other positions to change the jet state.

[0112] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
