[0007] Furthermore, the cleaning disc is in the shape of a disc, and the transmission assembly includes a disc-shaped rotating disc and a transmission rack coaxially arranged with the cleaning disc. A transmission gear ring is circumferentially arranged on the outer surface of the rotating disc, and the transmission gear ring can mesh with the transmission rack. The transmission rack is arranged on the spray arm and is in the shape of an arc with the rotation center axis of the spray arm as the center. When the spray arm rotates under the drive of the water flow, the engagement of the transmission rack and the transmission gear ring can drive the rotating disc to rotate, and the rotating disc is coaxially arranged with the cleaning disc, so as to realize the driving of the cleaning disc.

[0008] Furthermore, the rotating disk is arranged above the drain plate and below the spray arm, and the transmission rack includes a first rack and a second rack that can respectively mesh with the transmission gear ring, and the first rack and the second rack are symmetrically arranged on the bottom surface of both sides of the spray arm with the center of the spray arm as the center. During the operation of the cleaning machine, the spray arm rotates continuously, so that the first rack and the second rack can continuously and intermittently mesh with the transmission gear ring, thereby enabling the cleaning disk to continuously clean the heating disk during operation, and better avoiding the accumulation of dirt on the surface of the heating disk.

[0009] Furthermore, the interior of the rotating disk is hollow to form a water inlet cavity, a spray hole communicating with the water inlet cavity is provided on the top wall of the rotating disk, and a water inlet port is provided on the bottom wall.

[0010] The invention also includes a centrifugal impeller and a water collecting chamber, wherein the water collecting chamber is communicated with the flow channels on both sides of the spray arm respectively, the centrifugal impeller is arranged in the water collecting chamber and can rotate around the rotation center axis of the spray arm, a water outlet hole is provided on the cavity wall of the water collecting chamber, and the rotating disk can move up and down relative to the cleaning disk along the axial direction and has at least two states:

[0011] In the first state, the transmission gear ring on the rotating disk meshes with any rack and rotates, and the water outlet is not connected to the water inlet port. At this time, the rotating disk plays a transmission role to realize the rotation of the cleaning disk;

[0012] In the second state, the transmission gear ring and each rack on the rotating disk are disengaged up and down, and the water outlet is fluidly connected with the water inlet port, so that the water entering the water inlet chamber is sprayed out from the spray hole. At this time, the cleaning disk stops rotating, and the rotating disk sprays the water entering the water inlet chamber from the spray hole, and can achieve fixed-point enhanced cleaning of the tableware on the basis of the spray arm, so that the heavy oil stains on the tableware can be thoroughly cleaned, thereby improving the cleaning effect of the tableware.

[0013] Furthermore, the water inlet port is opened at the center of the bottom of the rotating disk, and the water inlet port is connected to a vertically extending water inlet sleeve. A guide sleeve is vertically arranged on the drain plate. The guide sleeve is located on the side wall of the upper part of the drain plate and is provided with a conducting port that can be fluidically connected with the water outlet hole of the water collection chamber.

In this way, in the second state, the rotation of the rotating impeller can simultaneously drive the rotation of the rotating disk and the cleaning disk. On the one hand, the rotating disk can realize the rotation and spraying of the tableware, thereby improving the cleaning effect of the heavy oil stains on the tableware, and on the other hand, the cleaning disk can also continuously clean the surface of the heating disk in the second state, and the driving of the rotating impeller does not require a separate driving device.

[0017] Furthermore, the rotating impeller comprises a central sleeve arranged vertically and blades arranged on the outer surface of the central sleeve at intervals along the circumferential direction, each blade is arranged vertically, and the outer side of the upper end of each blade is concave inwards and circumferentially assembled into the above-mentioned ring step, and the extension direction of each blade deviates from the diameter direction of the central sleeve, so that the water flow at the water guide hole can better drive the rotating impeller to rotate.

In addition, the rotation of the cleaning disk is driven by the spray arm, and no additional driving device is required, thereby simplifying the internal structure of the cleaning machine.

The impeller assembly 42 is arranged at the upper end of the power output shaft of the power assembly 41, and includes a centrifugal impeller 421 located at the upper part and an axial flow impeller 422 located at the lower part. Furthermore, the spray arm 2 is rotatably supported on the top of the guide seat 43 through its water inlet 21, and the roughly disc-shaped water collecting chamber 20 in the center of the spray arm 2 and the top of the guide seat 43 form a water collecting chamber 40, the centrifugal impeller 421 is installed in the water collecting chamber 40, and the axial flow impeller 422 is located at the upper part of the water supply channel 44.

The cleaning plate 5 includes a plate body 50 and bristles 51 which are arranged on the bottom surface of the plate body 50 and can contact the top surface of the above-mentioned heating plate 3. The cleaning plate 5 is linked with the above-mentioned spray arm 2 through the transmission assembly 6 and can rotate circumferentially along the top surface of the heating plate 3 with the central axis of the heating plate 3 as the center.

[0041] In the present invention, the cleaning disk 5 can rotate along the circumferential direction of the top surface of the heating disk 3 so that the bristles 51 of the cleaning disk 5 can clean the top surface of the heating disk 3, thereby preventing dirt from accumulating on the heating disk 3 and ensuring the heating efficiency of the heating disk 3. In addition, the rotation of the cleaning disk 5 is driven by the spray arm 2, and no additional driving device is required, thereby making the internal structure of the cleaning machine simple. Preferably, in this embodiment, the cleaning disk 5 and the heating disk 3 are arranged vertically opposite to each other, and the sizes of the two are matched, so that the heating disk 3 can be better cleaned.

[0042] Furthermore, the cleaning disc 5 is in the shape of a disc, and the transmission assembly 6 includes a disc-shaped rotating disc 61 and a transmission rack coaxially arranged with the cleaning disc 5. A transmission ring gear 611 is circumferentially arranged on the outer surface of the rotating disc 61, and the transmission ring gear 611 can mesh with the transmission rack, and the transmission rack is arranged on the spray arm 2 and is in the shape of an arc centered on the rotation center axis of the spray arm 2. When the spray arm 2 rotates under the drive of the water flow, the engagement of the transmission rack and the transmission ring gear 611 can drive the rotating disc 61 to rotate, and the rotating disc 61 is coaxially arranged with the cleaning disc 5, so that the cleaning disc 5 can be driven.

[0043] Furthermore, the rotating disk 61 is hollow inside to form a water inlet chamber 610, and a spray hole 612 communicating with the water inlet chamber 610 is provided on the top wall of the rotating disk 61, and a water inlet port 613 is provided on the bottom wall. It also includes a centrifugal impeller 421 and a water collecting chamber 40, and the water collecting chamber 40 is communicated with the flow channels on both sides of the spray arm 2 respectively. The centrifugal impeller 421 is arranged in the water collecting chamber 40 and can rotate around the rotation center axis of the spray arm 2, and a water outlet hole 431 is provided on the cavity wall of the water collecting chamber 40. In addition, the rotating disk 61 can move up and down along the axial direction relative to the cleaning disk 5, and has at least two states:

[0044] In the first state, the transmission ring gear 611 on the rotating disk 61 meshes with any rack and rotates, and the water outlet 431 is not connected to the water inlet port 613. At this time, the rotating disk 61 plays a transmission role to realize the rotation of the cleaning disk 5;

[0045] In the second state, the transmission gear ring 611 on the rotating disk 61 is disengaged from each rack up and down, and the water outlet hole 431 is fluidly connected with the water inlet port 613 so that the water entering the water inlet chamber 610 is ejected from the injection hole 612. At this time, the cleaning disk 5 stops rotating, and the rotating disk 61 can realize the fixed-point enhanced cleaning of the tableware on the basis of the spray arm 2 by ejecting the water entering the water inlet chamber 610 from the injection hole 612, so that the heavy oil stains on the tableware can be thoroughly cleaned, and the cleaning effect of the tableware is improved. In this embodiment, the water outlet hole 431 is opened on the periphery of the top surface of the guide seat 43. In this way, under the action of the centrifugal force of the centrifugal impeller 421, the water in the water collecting chamber 40 can flow into the water outlet hole 431 better.

[0046] Furthermore, the water inlet port 613 is provided at the center of the bottom of the rotating disk 61, and the water inlet port 613 is connected to a water inlet sleeve 614 extending vertically, and a guide sleeve 122 is vertically arranged on the drain plate 12. The guide sleeve 122 is located on the side wall above the drain plate 12 and is provided with a guide port 1221 that can be fluidically connected with the water outlet hole 431 of the water collecting chamber 40. The water inlet sleeve 614 is tightly fitted and penetrated in the guide sleeve 122 and can rotate and move up and down relative to the guide sleeve 122. It also includes a vertically arranged rotating connector 7, the upper end of which is connected to the water inlet sleeve 614 and circumferentially surrounds the water guide port 71 with the lower pipe opening of the water inlet sleeve 614, and the lower end is connected to the center of the cleaning disk 5. Furthermore, in the first state, the water guide port 71 and the conduction port 1221 are staggered up and down and the wall of the water inlet sleeve 614 shields the conduction port 1221. In the second state, the water guide port 71 and the conduction port 1221 are always connected inside and outside. On the one hand, the rotation of the water inlet sleeve 614 relative to the guide sleeve 122 can realize the rotation of the cleaning disc 5 driven by the rotating disc 61. On the other hand, the up and down movement of the water inlet sleeve 614 relative to the guide sleeve 122 can realize the on-off control of the water outlet 431 and the water inlet port 613. In this embodiment, a conduction joint 1223 is provided on the conduction port 1221, and the conduction joint 1223 is connected to the water outlet 431 through the water guide pipe 8.

[0047] Further, in this embodiment, the rotating connector 7 includes a tube body 70 with a closed top and a rotating impeller 72 fixed on the top surface of the tube body 70. The rotating impeller 72 is arranged with the central axis of the tube body 70 as the center, and the outer side of the upper end of the rotating impeller 72 is circumferentially recessed inward to form a ring step (not shown), and the lower end of the water inlet sleeve 614 is circumferentially embedded and fixed in the ring step (in this embodiment, the rotating disk 6, the water inlet sleeve 614 and the rotating connection 7 are an integral part), and the lower edge of the water inlet sleeve 614 and the top edge of the tube body 70 are circumferentially surrounded by the water guide port 71, and the rotating impeller 72 can rotate under the driving of the water inlet flow at the guide port 1221. In this way, in the second state, the rotating disk 61 is driven to rotate by the rotation of the rotating impeller 72, so that the rotating disk 61 can rotate and spray the tableware, thereby improving the cleaning effect of the heavy oil stains on the tableware.

[0048] Preferably, in order to enable the incoming water flow at the guide port 1221 to better drive the rotating impeller 72 to rotate, the rotating impeller 72 includes a vertically arranged central sleeve 721 and blades 722 arranged on the outer surface of the central sleeve 721 at circumferential intervals. Each blade 722 is vertically arranged, and the outer side of the upper end of each blade 722 is respectively fixed to the inner side surface of the above-mentioned water inlet sleeve 614, and the extension direction of each blade 722 deviates from the diameter direction of the central sleeve 721. In addition, an upper annular rib 6141 and a lower annular rib 6142 are convexly arranged on the outer surface of the water inlet sleeve 614 at intervals in the circumferential direction. The guide sleeve 122 has a certain elasticity, and the upper annular rib 6141 and the lower annular rib 6142 are respectively against the inner surface of the guide sleeve 122 in the circumferential direction. In the first state, the lower annular rib 6142 is located above the conducting port 1221, and in the second state, the conducting port 1221 is located between the upper annular rib 6141 and the lower annular rib 6142. On the one hand, the water inlet sleeve 614 and the guide sleeve 122 can be tightly connected, so that the water inlet sleeve 614 can be more stably rotated or moved up and down relative to the guide sleeve 122. On the other hand, it is better to prevent water from penetrating into the water guide port 71 when the conducting port 1221 is not connected to the water guide port 71, and to prevent water from leaking from the upper and lower ends of the water guide port 71 when the conducting port 1221 is connected to the water guide port 71.

[0049] In this embodiment, the lower end of the rotating connector 7 is threadedly connected to the connecting sleeve 52 on the top surface of the cleaning tray 5, so as to realize a stable connection between the rotating connector 7 and the cleaning tray 5. Specifically, an internal thread 711 is provided on the inner side surface of the tube body 70 of the rotating connector 7, and an external thread 521 that can be threadedly connected to the internal thread 711 is provided on the outer side surface of the connecting sleeve 52 of the cleaning tray 5. In this way, the connecting sleeve 52 is screwed into the lower pipe opening of the tube body 70 to realize the threaded connection between the lower end of the rotating connector 7 and the cleaning tray 5.

[0050] In addition, preferably, a limiting rib 1222 is convexly provided on the inner side surface of the lower end of the guide sleeve 122 along the circumferential direction, and a first limiting ring groove 712 and a second limiting ring groove 713 are concavely provided on the outer side surface of the tube body 70 along the circumferential direction at intervals from top to bottom. Moreover, in the first state, the limiting rib is embedded in the first limiting ring groove 712 and can rotate circumferentially along the first limiting ring groove 712, while in the second state, the limiting rib is embedded in the second limiting ring groove 713 and can rotate circumferentially along the second limiting ring groove 713. Thus, the rotating disk 61 can be better positioned in the first state or the second state, and stable rotation of the rotating disk 61 can be achieved in each state.

[0051] The working process of the present invention is as follows:

[0052] The power assembly 41 works to drive the centrifugal impeller 421 to rotate, and the centrifugal impeller 421 throws the water in the water collecting chamber 40 through the guide seat 43 to the flow channel in the spray arm 2 and the water outlet 431 of the guide seat 43 (at this time, the guide port 1221 is not connected to the water guide port 71). The water flows out from the water spray hole 22 of the spray arm 2, and the reaction force of the water flow drives the spray arm 2 to rotate, and the transmission rack rotates with the spray arm 2. When the first rack 62 or the second rack 63 is engaged with the transmission gear ring 611 on the rotating disk 61, the rotating disk 61 starts to rotate, thereby driving the lower cleaning disk 5 to rotate, and the bristles 51 on the cleaning disk 5 scrub the surface of the heating disk 3. During this process, the spray arm 2 rotates continuously, and the two racks on the spray arm 2 drive the rotating disk 61 repeatedly, so that the rotating disk 61 rotates continuously, so that the cleaning disk 5 rotates continuously, that is, the bristles 51 brush the heating disk 3 continuously.

[0053] When the rotating disk 61 is lifted up, the limiting rib 1222 is inserted into the first limiting ring groove 712.
