Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

Referring to fig. 1, the water tank type cleaning machine applied to the cover plate of the present invention includes a water tank body 1 and a cover plate 2 disposed at the top end of the water tank body 1, the water tank body 1 and the cover plate 2 form a closed washing space, a cleaning assembly including a motor, a water pump, a rotary spray arm, etc. is disposed in the washing space, when the motor drives the water pump to work, water is driven to spray through the rotary spray arm, the water is sprayed to all parts of the water tank body 1, and the cover plate 2 plays a role of preventing high-spray water from being sprayed to the outside. The above structure can be referred to in the prior art, and is not described in detail herein.

Referring to fig. 2 to 4, the cover plate 2 includes a glass panel 21 and a cover plate frame 22 at the bottom of the cover plate 2, and the cover plate frame 22 is provided therein for arranging a switch assembly and the like. In order to achieve a good cleaning effect on the top of the dishes, the cover plate 2 further comprises a motor 23, a water pump 24 and a spray arm 25. The top of the motor 23 is disposed in the cover plate frame 22, the middle of the cover plate frame 22 is provided with a mounting hole 221, the motor 23 passes through the mounting hole 221 and extends downwards from the bottom of the cover plate frame 22, the motor 23 and the cover plate frame 22 can be fixed by a screw 231, and an O-ring 232 is further disposed between the motor 23 and the cover plate frame 22 for sealing to prevent water from entering the cover plate frame 22.

The water pump 24 includes a centrifugal impeller 241 disposed in the spray arm 25, and a receiving cavity 251 with an upper opening is formed in the spray arm 25, such as in the middle, for receiving the centrifugal impeller 241, and the centrifugal impeller 241 turns water entering in the axial direction back and flows out in the radial direction. The bottom surface of spray arm 25 is provided with spray holes 252 for allowing water pumped into spray arm 25 by pump 24 to be sprayed downward onto the dishes. At the same time, the spray holes 252 are oriented such that the spray arms 25 rotate under the influence of the water flow.

A water accumulation seat 26 is provided around the motor 23 below the bottom surface of the cover frame 22, the water accumulation seat 26 has a hollow structure with an upper opening and a lower opening, and the water accumulation seat 26 extends downward from the bottom surface of the cover frame 22, thereby forming a water accumulation cavity 261 around and below the motor 23. The bottom of the water accumulation seat 26 is provided with support bars 262, the support bars 262 are distributed in a radial shape, and two adjacent support bars 262 are arranged at intervals. A shaft hole 263 is formed between ends of the support bars 262 near the middle so that the output shaft 233 of the motor 23 passes through to be connected to the centrifugal impeller 241 for driving, and vibration of the motor 23 can be reduced by the support of the support bars 262. The water collecting base 26 is connected and fixed with the cover plate frame 22 through the supporting column 264.

The spray arm 25 is located below the water accumulation seat 26, and a connecting seat 253 is formed by upward extending the middle opening of the top surface of the spray arm 25 and is used for being connected with the water accumulation seat 26. The top surface of connecting seat 253 and the bottom butt of ponding seat 26, the periphery of connecting seat 253 and ponding seat 26 bottom is provided with snap ring 254 to it is fixed through threaded connection with spray arm 25 and ponding seat 26.

A water guide plate 27 extending downward is formed around the mounting hole 221 of the cover frame 22, and the water guide plate 27 has a hollow cylindrical shape, surrounds the motor 23, and extends into the water collecting chamber 261. The bottom surface of the cover plate frame 22 forms a smooth inclined flow guide surface 222 which is gradually inclined upwards from the periphery to the middle for guiding the water impacting on the cover plate 2 into the water accumulation cavity 261, the water sprayed from the rotary spray arm at the bottom is collected in the water accumulation cavity 261, and the water guide plate 27 guides the water on the flow guide surface 222 of the cover plate frame 22 downwards into the water accumulation cavity 261. The water in the water accumulation chamber 261 flows into the impeller 241 through the spaces between the support bars 262, thereby being pumped into the shower arm 25 by the impeller 241.

Because the water can automatically flow downwards under the action of gravity, the water can be pressurized only by the centrifugal impeller 241, and an induction impeller is omitted. Because of the limited amount of water collected at the top, the volume of the spray holes 252 and spray arms 25 need to be matched to the amount of water collected, and thus the spray arms 25 are relatively small.

Referring to fig. 3, the arrows indicate the flow paths of water, and water impinging on the cover plate frame 22 moves upward along the inclined smooth flow guide surface 222, enters the water collecting cavity 261 after encountering the water guide plate 27, enters the centrifugal impeller 241 under the action of gravity, and then the motor 23 rotates to drive the centrifugal impeller 241 to rotate, so that the water is pressurized and then sprayed out from the spray holes 252 of the spray arm 25 to wash the top of the tableware.

Compared with the method of simply washing the upper parts of the dishes by water flow reflection, the method has better top washing effect of the tableware, and especially has more obvious effect on a large-water-tank dish washing machine with more tableware and double-layer placed tableware. Through setting up water conservancy diversion face, diversion board and ponding chamber, can introduce the ponding chamber with the water that strikes the apron effectively, the delivery pump pressurization and the top spray arm spray, realized the water transportation process of no pipeline, utilize the gravity of water simultaneously, also saved the induction impeller.
