[0002] At present, common dishwashers on the market generally include a cabinet and a spray device disposed in the cabinet, and the spray device is used to draw water from the bottom of the cabinet into a water spray component and spray it into the washing chamber to wash the dishes. The washing chamber volume of most dishwashers is fixed and cannot be changed according to the number of dishes to be washed.

[0003] In order to solve the above problems, the applicant's prior application CN202010664979.8 "A washing machine" discloses a cavity structure of a dishwasher, including a box body and a first spray device arranged at the lower part of the box body, and a partition assembly that can separate the box body into relatively independent upper space and lower space is also arranged in the box body, and the partition assembly includes a fixed plate and a movable plate that can cooperate with the fixed plate to separate the upper space from the lower space or connect the upper space with the lower space. When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate to separate the upper space from the lower space, the upper space is used to place the washed dishes, and the lower space is sprayed and washed separately, which makes full use of the box space and is conducive to saving water, electricity and other energy; when the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate to connect the upper space with the lower space, and washes the dishes in the upper space and the lower space; the above scheme can adjust the cleaning space according to the number of dishes to be washed, thereby meeting the needs of more consumers.

[0004] For the above-mentioned dishwasher, in order to facilitate the addition of detergent, rinse aid, etc., a dispenser for storing detergent and rinse aid is usually installed on the inner side of the door body, and the detergent and rinse aid are flushed into the washing chamber through the water flow ejected from the spray hole on the spray arm. However, for the dishwasher with the above-mentioned partition assembly, due to the obstruction of the partition, the water column ejected from the spray hole of the spray arm is partially blocked and it is difficult to achieve effective impact on the detergent and rinse aid, which affects the washing effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which can effectively impact detergent and rinse agent so as to improve the washing effect in view of the current status of the prior art.

[0008] A box body, which defines a washing chamber, and the front side of the box body has an opening;

[0009] A door body, arranged at the front side of the box body, used to open or close the opening;

[0010] A dispenser, used to store washing consumables, is located on the back of the door;

[0011] A partition assembly is used to separate the box into relatively independent upper and lower spaces, the partition assembly includes a fixed plate and a movable plate, the fixed plate is arranged near the rear side of the box, a gap is formed between the fixed plate and the front side wall of the box for connecting the upper space with the lower space, and the movable plate is slidably arranged on the fixed plate forward and backward and is used to open or close the gap;

[0012] The box body is provided with an inner water pipe arranged near the rear side wall of the box body and used for supplying water to the upper space. A flushing assembly is provided under the partition assembly, which can extend and retract forward and backward with the movement of the movable plate to flush the distributor when the gap is closed. The water inlet end of the flushing assembly is connected to the inner water pipe.

[0013] The utility model provides a flushing assembly in the partition assembly. When the movable plate retreats to a state where the gap is opened, the upper space is connected to the lower space, and without the obstruction of the partition, the original spray arm in the washing chamber can impact the dispenser to achieve the delivery of consumables. When the movable plate moves forward to a state where the gap is closed, the upper space is separated from the lower space. Although the partition will greatly affect the impact of the spray arm on the dispenser, at this time, the flushing assembly moves close to and toward the dispenser as the movable plate moves. Under the directional impact of the flushing assembly, the detergent and rinse agent can be effectively delivered, thereby improving the washing effect.

[0014] Preferably, the dispenser is located below the partition assembly, and when the movable plate closes the gap, the water outlet of the flushing assembly is located below the rear edge of the movable plate and is arranged obliquely toward the dispenser. The above structure is adopted to make the flushing assembly impact the dispenser more accurately, ensuring the effective delivery of detergent and rinse aid.

[0015] Preferably, the flushing assembly includes a fixed pipe, a movable pipe and a nozzle. The rear end of the fixed pipe is arranged near the rear edge of the fixed plate and is the water inlet end. The movable pipe is arranged at the front end of the fixed pipe and can be extended forward and backward. The nozzle is connected to the front end of the movable pipe. Preferably, a first limiting portion is arranged at the top of the nozzle, and correspondingly, a second limiting portion is arranged below the rear edge of the movable plate. When the movable plate moves forward, the movable pipe is driven to move forward by the cooperation of the first limiting portion and the second limiting portion. The above structure facilitates the expansion and contraction of the flushing assembly with the movement of the movable plate, and adapts to the state in which the upper space is connected or separated from the lower space.

[0016] Preferably, a driving assembly for driving the moving plate to move forward and backward is provided under the partition assembly. Preferably, the driving assembly includes a motor, a screw rod, and a nut pair. The motor is provided on the rear side wall of the box body. The screw rod is rotatably provided under the fixed plate and the rear end is connected to the output end of the motor. The front end of the screw rod extends to the rear edge of the moving plate. The nut pair is connected with the screw rod and constrained under the rear edge of the moving plate. The above structure facilitates the automatic movement of the moving plate.

[0017] Preferably, the bottom of the nut pair is provided with a claw that is through-through and has an open bottom. Correspondingly, the top of the nozzle is provided with a foot that can be clamped into the claw when the moving plate meets the nozzle and detached from the claw under the pulling force of the moving plate. Preferably, the foot includes a vertically extending connecting arm and a cylindrical clamping joint located at the upper end of the connecting arm. Correspondingly, a clamping groove adapted to the clamping joint is formed inside the claw. The above structure is adopted so that the moving plate will not interfere with the moving tube during the movement. When the moving plate covers the gap, the foot is constrained in the claw. When the moving plate moves backward, the foot and the moving tube are driven to move backward. When the moving tube is completely hidden in the fixed tube, the moving plate needs to continue to move backward, and the foot will be detached from the claw. When the moving plate moves forward again, when it moves to the point where the claw meets the foot, the foot is clamped into the claw axially. When the moving plate moves forward, it will move forward with the moving tube until the moving plate closes the gap and the nozzle at the front end of the moving tube approaches and is arranged toward the distributor.

[0018] Preferably, the diameter of the fixed tube is larger than that of the mobile tube, a clamping ring is formed at the front end of the fixed tube, and a clamping edge is formed at the rear end of the mobile tube which is inserted into the fixed tube and is engaged with the clamping ring. This structure facilitates the position limiting and sealing connection between the fixed tube and the mobile tube.

[0019] Preferably, the rear end of the fixed pipe is connected to the inner water pipe through a water guide hose. A bottom spray arm arranged near the bottom of the washing chamber is provided in the lower space, an upper spray arm arranged near the partition assembly is provided in the upper space, and an open water pump is provided at the bottom of the washing chamber, the first water outlet of the open water pump is connected to the bottom spray arm, and the second water outlet is connected to the lower end of the inner water pipe, and the inner water pipe extends upward to supply water to the upper spray arm.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the cleaning machine of this embodiment includes a box body 1, a door body 2, a dispenser 3, and a partition assembly 4. The interior of the box body 1 is hollow so as to define a washing chamber, and the front side of the box body 1 has an opening; the door body 2 is arranged on the front side of the box body, and is used to open or close the opening; the dispenser 3 is used to store washing consumables (such as detergents, rinse agents, etc.), and is arranged on the back side of the door body 2; the partition assembly 4 is used to separate the box body into relatively independent upper space and lower space, and the partition assembly 4 includes a fixed plate 41 and a movable plate 42, the fixed plate 41 is arranged close to the rear side of the box body, and a notch 43 is formed between the fixed plate 41 and the front side wall of the box body for connecting the upper space with the lower space, and the movable plate 42 can be slidably arranged on the fixed plate 41 back and forth and is used to open or close the notch 43.

[0027] An inner water pipe 5 is provided in the box body 1 and is arranged near the rear side wall of the box body 1 and is used to supply water to the upper space. A flushing assembly 6 is provided under the partition assembly 4 and can be extended and retracted forward and backward with the movement of the movable plate 42 so as to flush the distributor 3 when the notch 43 is closed. The water inlet end of the flushing assembly 6 is connected to the inner water pipe 5.

[0028] Specifically, the dispenser 3 is located under the partition assembly 4, and when the movable plate 42 closes the notch 43, the water outlet of the flushing assembly 6 is located under the rear edge of the movable plate 42 and is arranged obliquely toward the dispenser 3. With the above structure, the flushing assembly 6 can impact the dispenser 3 more accurately, ensuring the effective delivery of detergent and rinse aid.

[0029] The flushing assembly 6 of this embodiment includes a fixed pipe 61, a movable pipe 62 and a nozzle 63. The rear end of the fixed pipe 61 is arranged near the rear edge of the fixed plate 41 and is the water inlet end. The movable pipe 62 is arranged at the front end of the fixed pipe 61 and can be extended forward and backward. The nozzle 63 is connected to the front end of the movable pipe 62. A first limiting portion is arranged at the top of the nozzle 63. Correspondingly, a second limiting portion is arranged below the rear edge of the movable plate 42. When the movable plate 42 moves forward, the movable pipe 62 is driven to move forward by the cooperation of the first limiting portion and the second limiting portion. The above structure facilitates the expansion and contraction of the flushing assembly 6 with the movement of the movable plate 42, and adapts to the state where the upper space is connected or separated from the lower space.

[0030] A driving assembly for driving the moving plate 42 to move forward and backward is arranged under the partition assembly 4. The driving assembly includes a motor 44, a screw rod 45, and a nut pair 46. The motor 44 is arranged on the rear side wall of the box body 1. The screw rod 45 is rotatably arranged under the fixed plate 41 and the rear end is connected to the output end of the motor 44. The front end of the screw rod 45 extends to the rear edge of the moving plate 42. The nut pair 46 is matched with the screw rod 45 and is constrained under the rear edge of the moving plate 42 by screws. The above structure facilitates the automatic movement of the moving plate 42.

[0031] The bottom of the nut pair 46 is provided with a claw 461 (i.e., the second limiting portion) which is through-through and has an opening 462 at the bottom. Correspondingly, the top of the nozzle 63 is provided with a foot 631 (i.e., the first limiting portion) which can be inserted into the claw 461 when the moving plate 42 and the nozzle 63 meet and can be separated from the claw 461 under the pulling force of the moving plate 42. The foot 631 includes a vertically extending connecting arm 6311 and a cylindrical connecting joint 6312 located at the upper end of the connecting arm 6311. Correspondingly, a groove 463 adapted to the connecting joint 6312 is formed inside the claw 461. The above structure is adopted so that the moving plate 42 will not interfere with the moving tube 62 during the moving process. When the movable plate 41 covers the gap 43, the clamping foot 631 is constrained in the claw 461. When the movable plate 42 moves backward, it drives the clamping foot 631 and the movable tube 62 to move backward. When the movable tube 62 is completely hidden in the fixed tube 61, the movable plate 42 needs to continue to move backward, and the clamping foot 631 will be disengaged from the claw 461; when the movable plate 42 moves forward again, when it moves to the point where the claw 461 meets the clamping foot 631, the clamping foot 631 is axially clamped into the claw 461. When the movable plate 42 moves forward, it will move the movable tube 62 forward with it until the movable plate 42 closes the gap 43 and the nozzle 63 at the front end of the movable tube 62 approaches and is arranged toward the distributor 3.

[0032] The diameter of the fixed tube 61 is larger than that of the movable tube 62. A clamping ring 611 is formed at the front end of the fixed tube 61. The rear end of the movable tube 62 is inserted into the fixed tube 61 and a clamping edge 621 is formed at the rear end to be engaged with the clamping ring 611. This structure facilitates the position limiting and sealing connection between the fixed tube 61 and the movable tube 62.

[0033] The rear end of the fixed pipe 61 is connected to the inner water pipe 5 through a water guide hose 64. A bottom spray arm 7 arranged near the bottom of the washing chamber is provided in the lower space, an upper spray arm 8 arranged near the partition assembly 4 is provided in the upper space, and an open water pump is provided at the bottom of the washing chamber, the first water outlet of the open water pump is connected to the bottom spray arm 7, and the second water outlet is connected to the lower end of the inner water pipe 5, and the inner water pipe 5 extends upward to supply water to the upper spray arm 8. The rear end of the fixed pipe 61 is connected to the inner water pipe 5 through a water guide hose 64, so as to facilitate the water supply to the flushing distributor 3.

[0034] In this embodiment, a flushing assembly 6 is provided on the partition assembly 4. When the movable plate 41 retreats to open the gap 43, the upper space is connected with the lower space, and without the obstruction of the partition, the original spray arm in the washing chamber can impact the dispenser to achieve the delivery of consumables; when the movable plate 42 moves forward to close the gap 43, the upper space is separated from the lower space. Although the partition will greatly affect the impact of the spray arm on the dispenser 3, at this time, the flushing assembly 6 moves close to and toward the dispenser 3 as the movable plate 42 moves. Under the directional impact of the flushing assembly 6, the detergent and rinse agent can be effectively delivered, thereby improving the washing effect.
