Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and specifically refers to a cleaning machine for cleaning tableware and fruits and vegetables. Background Art

[0002] As a device for automatically cleaning tableware such as bowls, chopsticks, plates, dishes, knives, and forks, dishwashers have been widely used in families at home and abroad.

[0003] The "Dishwasher" (Application No.: CN202420198297.6) with the authorization announcement number CN221105772U discloses a front-opening dishwasher structure. The top wall of the inner tank of the dishwasher is usually a flat structure, or an uneven structure is made due to production needs.

[0004] During the cleaning process, the upward jet of water column will continuously strike the lower surface of the top wall of the inner tank. The water on the lower surface of the top wall of the inner tank usually falls randomly when it returns, and cannot be effectively utilized; moreover, the drying structure of the dishwasher is generally arranged on the side of the cabinet. Since the gas flow speed at the top of the inner tank is relatively slow, it is difficult to effectively dry the lower surface of the top wall of the inner tank far from the cabinet, resulting in possible dripping problems after washing, which affects the cleaning effect of the tableware. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine that can directionally guide the water that returns after impacting the top wall of the inner tank, thereby improving the utilization rate of washing water and avoiding water droplets from dripping on the top wall of the inner tank, in view of the current situation of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0007] A cleaning machine includes an inner tank. A guiding part extending from the center to each corner is arranged on the top wall of the inner tank. The guiding part is formed by a local downward concave of the top wall of the inner tank. The lower surface of the guiding part is gradually inclined downward from the middle of the top wall of the inner tank to the end and forms a falling-back area at the end.

[0008] The utility model arranges a guiding part extending from the center to each corner on the top wall of the inner tank, and forms a falling-back area at the end of the guiding part, so that the water column after impacting the top wall of the inner tank converges along the guiding part in the falling-back area, and the returned water falls from the falling-back area concentratedly. The concentratedly falling returned water can perform secondary cleaning on the tableware in a specific area below, thereby improving the utilization rate of washing water; during drying, the guiding part forms a guiding path for the air flow from the top wall of the inner tank to the four corners, thereby improving the drying effect of the top wall of the inner tank and avoiding the problem of water droplets dripping on the top wall of the inner tank.

[0009] Preferably, the guiding part as a whole is in an X-shaped structure. The ends of the X-shaped structure are in smooth transition, and the bottom wall of the smooth transition area is horizontally arranged to form the falling-back area. With the above structure, it is not only convenient to form a guiding structure with a regular path, but also convenient for production and manufacturing.

[0010] Preferably, the width of each extending arm of the X-shaped structure gradually decreases from the inner end to the outer end. This structure can converge the backwater more concentratedly to improve the local secondary cleaning effect.

[0011] Preferably, each extending arm of the X-shaped structure is respectively arranged along the diagonal of the inner tank top wall, and each of the falling-back areas is arranged close to the corner of the inner tank top wall. This structure can focus on the corners of the inner tank where cleaning dead corners are likely to occur corresponding to the falling-back areas, so as to eliminate the cleaning dead corners and improve the cleaning effect.

[0012] Preferably, the central part of the X-shaped structure is arranged corresponding to the central part of the inner tank top wall, and the central part of the X-shaped structure bulges upward to form a central confluence area. For the spray arm using an open pump, since no spray holes are usually provided in the central part of the spray arm, the washing power in the central part of the washing cavity is relatively weak. With the above structure, the converged water flow is arranged in the center of the inner tank top and guided downward, which is beneficial to improving the cleaning effect on the tableware in the central part of the washing cavity.

[0013] Preferably, the central confluence area is circular, the lower surface of the central confluence area is higher than the lower surface of its peripheral guiding part, and the edge of the lower surface of the central confluence area is smoothly connected with the lower surface of its peripheral guiding part. With the above structure, on the one hand, it is convenient to form falling-back drainage in the central area, and on the other hand, it does not affect the guiding of other water flows to the falling-back area.

[0014] Preferably, a bowl basket is arranged in the inner tank, and a first tableware placement area is arranged in the bowl basket corresponding to the central confluence area. The first tableware placement area can place relatively difficult-to-clean tableware to perform secondary cleaning by means of the backwater in the falling-back area and improve the cleaning effect.

[0015] Preferably, a bowl basket is arranged in the inner tank, and a second tableware placement area is arranged in the bowl basket corresponding to the falling-back area. The second tableware placement area can place larger objects to be cleaned to perform secondary cleaning by means of the backwater in the central confluence area and improve the cleaning effect.

[0016] Preferably, a concave backwater area is arranged at the bottom of the inner tank, a spray arm capable of spraying water columns upward is arranged in the inner tank, and a water pumping mechanism for pumping the water in the backwater area to the spray arm is arranged at the bottom of the inner tank.

[0017] Compared with the prior art, the advantages of the present utility model are as follows: the present utility model is provided with a diversion part extending from the center to each corner on the top wall of the inner container, and a falling-back area is formed at the end of the diversion part, so that the water column after impacting the top wall of the inner container converges along the diversion part in the falling-back area, and the returned water falls from the falling-back area centrally, and the centrally falling returned water performs secondary cleaning on tableware in a specific area below, thereby improving the utilization rate of washing water; during drying, the diversion part forms a guiding path for the air flow from the top wall of the inner container to the four corners, thereby improving the drying effect of the top wall of the inner container and avoiding the problem of water droplets dripping from the top wall of the inner container.

[0021] The present utility model will be further described in detail below in conjunction with the embodiments of the drawings.

[0022] As Figures 1 to 3 shown, the cleaning machine of this embodiment includes an inner container 1, and a diversion part 2 extending from the center to each corner is provided on the top wall of the inner container 1. The diversion part 2 is formed by locally recessing downward from the top wall of the inner container 1. The lower surface of the diversion part 2 is gradually inclined downward from the middle of the top wall of the inner container 1 to the end to form a diversion surface 22, and a falling-back area 21 is formed at the end of the diversion surface 22.

[0023] In this embodiment, a diversion part 2 extending from the center to each corner is provided on the top wall of the inner container 1, and a falling-back area 21 is formed at the end of the diversion part 2, so that the water column after impacting the top wall of the inner container 1 converges along the diversion part 2 in the falling-back area 21, and the returned water falls from the falling-back area 21 centrally, and the centrally falling returned water performs secondary cleaning on tableware in a specific area below, thereby improving the utilization rate of washing water; during drying, the diversion part 2 forms a guiding path for the air flow from the top wall of the inner container 1 to the four corners, thereby improving the drying effect of the top wall of the inner container 1 and avoiding the problem of water droplets dripping from the top wall of the inner container 1.

[0024] The diversion part 2 is integrally in an X-shaped structure, the end of the X-shaped structure is in smooth transition, and the bottom wall of the smooth transition area is horizontally arranged to form the falling-back area 21. With the above structure, it is not only convenient to form a diversion structure with a regular path, but also convenient for production and manufacturing.

[0025] The width of each extension arm 200 of the X-shaped structure gradually decreases from the inner end to the outer end. This structure can converge the backflow of water more concentratedly to improve the local secondary cleaning effect.

[0026] Each extension arm 200 of the X-shaped structure is arranged along the diagonal of the top wall of the inner tank 1 respectively, and each falling-back area 21 is arranged close to the corner of the top wall of the inner tank 1. This structure can focus on the corner of the inner tank 1 corresponding to the falling-back area 21 where cleaning dead corners are likely to occur, so as to eliminate the cleaning dead corners and improve the cleaning effect.

[0027] The central part of the X-shaped structure is arranged corresponding to the central part of the top wall of the inner tank 1, and the central part of the X-shaped structure bulges upward to form a central confluence area 23. For the spray arm 4 using an open pump, since no spray holes are usually provided in the central part of the spray arm 4, the washing power in the central part of the washing cavity is relatively weak. With the above structure, the converging water flow is guided downward at the center of the top of the inner tank 1, which is beneficial to improving the cleaning effect on the tableware in the central part of the washing cavity.

[0028] The central confluence area 23 is circular, the lower surface of the central confluence area 23 is higher than the lower surface of its peripheral diversion part 2, and the edge of the lower surface of the central confluence area 23 is smoothly connected with the lower surface of its peripheral diversion part 2. With the above structure, on the one hand, it is convenient to form a falling-back and diversion in the central area, and on the other hand, it does not affect the guidance of other water flows to the falling-back area 21.

[0029] A bowl basket 3 is arranged in the inner tank 1, and a first tableware placement area is arranged in the bowl basket 3 corresponding to the central confluence area 23. Relatively difficult-to-clean tableware can be placed in the first tableware placement area to perform secondary cleaning by means of the backflow water in the falling-back area 21, so as to improve the cleaning effect.

[0030] A bowl basket 3 is arranged in the inner tank 1, and a second tableware placement area is arranged in the bowl basket 3 corresponding to the falling-back area 21. Larger objects to be cleaned can be placed in the second tableware placement area to perform secondary cleaning by means of the backflow water in the central confluence area 23, so as to improve the cleaning effect.

[0031] A concave backflow area 11 is arranged at the bottom of the inner tank 1, a spray arm 4 capable of spraying water columns upward is arranged in the inner tank 1, and a water pumping mechanism for pumping the water in the backflow area 11 to the spray arm 4 is arranged at the bottom of the inner tank 1.

[0032] In this embodiment, a diversion part 2 extending from the center to each corner is provided on the top wall of the inner tank 1, and a falling-back area 21 is formed at the end of the diversion part 2, so that the water column after impacting the top wall of the inner tank 1 converges along the diversion part 2 in the falling-back area 21, and the returned water falls from the falling-back area 21 in a concentrated manner. The concentrated falling-back water performs secondary cleaning on the tableware in a specific area below, thereby improving the utilization rate of the washing water. During drying, the diversion part 2 forms a guiding path for the airflow from the top wall of the inner tank 1 to the four corners, thereby improving the drying effect of the top wall of the inner tank 1 and avoiding the problem of water droplets dripping from the top wall of the inner tank 1.
