Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, in particular to a dishwasher capable of automatically isolating residues. Background Art

[0002] A washing machine is a device that sprays cold or hot water onto dishes to be cleaned to remove dirt adhering to them. For example, Chinese invention patent application CN109717803A, "A slag basket structure for a washing machine and a washing machine using the slag basket structure" (Application No.: CN201711034814.7), discloses a sink-type dishwasher structure.

[0003] When the above-mentioned cleaning machine is working, the cleaning water is circulated and filtered by covering the tank with a drain plate. The drain plate is provided with a through hole for installing a slag basket assembly. The residues washed off the objects to be cleaned are collected in the slag basket assembly. The general cleaning process includes cleaning, rinsing and other links. Taking the cleaning link as an example, the cleaning water must be filtered through the drain plate each time before entering the water pump, and the cycle is repeated. Since the slag basket is in an open state relative to the entire cleaning chamber, the residue in the slag basket must be flushed once after each cleaning water is filtered through the drain plate. This design accelerates the decomposition of the residue (from large particles to small particles). The decomposed small particle residues can easily flow through the drain plate into the water pump and adhere to the blades or the inner side of the spray arm, causing the water pump or the spray arm to be blocked, which is not conducive to maintenance. In addition, each flushing of the water flow needs to circulate through the residue in the slag basket assembly. Therefore, for a single cleaning link, the cleanliness of the cleaning water cannot be guaranteed. Moreover, if the residue is not cleaned in time, its odor can easily spread throughout the washing chamber. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a cleaning machine which can automatically isolate residues from the washing chamber, thereby improving the cleaning degree and preventing the spread of odor, in response to the current status of the existing technology.

[0005] The second technical problem to be solved by the present invention is to provide a cleaning machine which is convenient for collecting and discharging slag and can automatically isolate residues in view of the current status of the existing technology.

[0006] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cleaning machine that can automatically isolate residues, comprising a box body with a washing chamber, a locally concave drain area is provided at the bottom of the box body, the top of the drain area is covered with a drain plate, and a slag collecting port for slag discharge is provided on the drain plate, and it is characterized in that: a slag discharge port is provided on the bottom wall of the box body at the corresponding slag collecting port, and a slag collecting box connected to the slag discharge port is provided under the box body, and a slag collecting box is provided with a slag basket assembly that can be raised and lowered to connect or isolate the slag collecting box from the washing chamber.

[0007] In the above solution, the slag basket assembly includes a base and a slag basket. The base can be raised and lowered in the slag collection box. The slag basket is located above the base. The top of the slag basket has an end cap that can cover the slag discharge port. The side of the slag basket has a slag inlet that is arranged near the end cap and can be exposed above the drain plate. In the slag collection state, the slag basket rises until the slag inlet is located above the drain plate, facilitating slag collection. In the cleaning state or after slag collection is completed, the slag basket descends until it is completely hidden in the slag collection box. The end cap on the top of the slag basket covers and seals the slag discharge port, thereby preventing residue from overflowing from the slag collection box, keeping the water flow of the secondary cleaning clean, and preventing the spread of odor.

[0008] Preferably, a support ring is provided on the side of the slag basket, positioned near the lower edge of the slag inlet. When the slag basket is raised to the slag inlet and at least partially positioned above the slag collection port, the outer edge of the support ring abuts the inner edge of the slag collection port. This structure helps improve the seal between the slag basket and the drain plate during slag collection, preventing residue from entering the drain area through the gap between the slag basket and the drain plate, thereby preventing residue from flowing back into the pump.

[0009] In the above solution, the outer wall of the slag basket is provided with multiple filter openings, located below the support ring. A filter screen covers the outer periphery of the slag basket, and when the slag basket is raised to the slag inlet and at least partially positioned above the slag collection port, the filter openings and filter screen are located in the drainage area. This structure improves filtering effectiveness and facilitates drainage.

[0010] Preferably, the end cover of the slag basket is provided with an observation window for observing the slag accumulation in the slag basket. This structure facilitates the user to observe the slag accumulation and thus decide whether to clean it.

[0011] To facilitate assembly and connection, a slot is provided on the upper wall of the base. Correspondingly, a buckle is provided on the bottom of the slag basket that engages with the slot. The slag basket is detachably secured to the base through the engagement of the buckle and the slot. This structure makes it easy to remove the slag basket for cleaning or debris removal.

[0012] Preferably, a step is formed on the lower side of the upper opening of the slag collecting box, which can abut against the upper edge of the base to limit the base in the slag collecting box, so as to improve the operating stability of the slag basket assembly.

[0013] Preferably, a slag outlet is provided on the bottom wall of the slag collecting box, and correspondingly, a slag outlet is provided on the base for the residue collected by the slag basket to be discharged from the slag outlet, so as to facilitate slag and water discharge.

[0014] The cleaning machine of the present invention also includes a drive mechanism for driving the base up and down. This drive mechanism is located at the bottom of the slag collection box and partially extends through the bottom wall of the slag collection box to connect to the base. The drive mechanism includes a motor, a screw, and a nut pair. The nut pair is located on the base. The screw is arranged vertically, with its upper end connected to the nut pair and its lower end connected to the output shaft of the motor. The motor is located at the bottom of the slag collection box and is used to drive the screw. This drive mechanism has a simple and reasonable structure, which facilitates stable driving of the slag basket.

[0015] Preferably, a protective cover extending upward and used to accommodate the screw rod is provided at the central portion of the base, and the nut pair is provided at the lower end of the protective cover. This structure isolates the driving mechanism from the water environment to improve the reliability of the mechanism operation.

[0016] Compared with the prior art, the advantages of the present invention are: a slag discharge port is opened on the bottom wall of the box body of the present invention at the corresponding slag collection port, and a slag collection box connected to the slag discharge port is provided under the box body. When the slag basket assembly rises, the slag collection box is connected to the washing chamber, and slag can be collected at this time; when the slag basket assembly descends, the slag collection box is isolated from the washing chamber, thereby isolating the residue in the slag collection box and not connecting with the washing chamber, so as to avoid the residue from contaminating the water for secondary washing, improve the cleanliness, and avoid the odor of the residue from spreading to the washing chamber, thereby improving the user experience.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 6 As shown, the cleaning machine capable of automatically isolating residues in this embodiment includes a housing 1 having a washing chamber 10. A partially concave drain area 11 is provided at the bottom of the housing 1. The top of the drain area 11 is covered with a drain plate 12, and a slag collection port 121 for slag discharge is provided on the drain plate 12. The cleaning machine also has a water pumping mechanism for pumping water from the drain area 11 to above the drain plate 12. The water pumping mechanism is provided in the central portion of the bottom of the housing 1. The drain plate 12 has an opening 122 for mounting the water pumping mechanism. Since the water pumping mechanism is located in the central portion, the slag collection port 121 is located to the side of the opening 122.

[0025] In this embodiment, a slag discharge port 13 is provided on the bottom wall of the box body 1 at a position corresponding to the slag collecting port 121, and a slag collecting box 2 connected to the slag discharge port 13 is provided below the box body 1. The slag collecting box 2 is provided with a slag basket assembly 3 that can be raised and lowered to connect or isolate the slag collecting box 2 and the washing chamber 10.

[0026] The above-mentioned slag basket assembly 3 includes a base 31 and a slag basket 32. The base 31 can be raised and lowered in the slag collecting box 2. The slag basket 32 ​​is arranged above the base 31. The top of the slag basket 32 ​​has an end cover 321 that can cover the slag discharge port 13. The side of the slag basket 32 ​​is provided with a slag inlet 322 that is arranged close to the end cover 321 and can be exposed above the drain plate 12.

[0027] The slag basket 32 ​​of this embodiment is provided with a support ring 323 on the side thereof, arranged near the lower edge of the slag inlet 322. When the slag basket 32 ​​rises to a point where most of the slag inlet 322 is located above the slag collection port 121, the outer edge of the support ring 323 is close to the inner edge of the slag collection port 121. A first sealing ring 100 is provided on the outer periphery of the end cover 321 to better seal the slag discharge port 13; a second sealing ring 200 is provided on the outer edge of the support ring 323 to enable a closer and more compact fit with the slag collection port 121 on the drain plate 12. The above structure is conducive to improving the sealing performance between the slag basket 32 ​​and the drain plate 12 in the slag collection state, preventing residue from entering the drain area 11 through the gap between the slag basket 32 ​​and the drain plate 12, thereby preventing residue from flowing back into the pump.

[0028] The outer wall of the slag basket 32 ​​is provided with multiple filter openings 324, located below the support ring 323. A filter screen 325 covers the outer periphery of the slag basket 32, covering each filter opening 324. When the slag basket 32 ​​is raised to a position where the majority of the slag inlet 322 is located above the slag collection port 121, the filter openings 324 and filter screen 325 are located within the drainage area 11. This structure improves filtering effectiveness and facilitates drainage.

[0029] In this embodiment, the end cap 321 of the slag basket 32 ​​is provided with an observation window 3211 for observing the slag accumulation within the slag basket 32. This structure allows the user to observe the slag accumulation and determine whether it needs to be cleaned. To facilitate assembly and connection, a slot 311 is provided on the upper wall of the base 31. Correspondingly, a buckle 326 is provided on the bottom of the slag basket 32, which mates with the slot 311. The slag basket 32 ​​is detachably restrained to the base 31 through the mating structure of the buckle 326 and the slot 311, making it easy to remove the slag basket 32 ​​for cleaning or removing residue.

[0030] In this embodiment, the lower side of the upper end of the slag collecting box 2 is formed with a step 21 that abuts against the upper edge of the base 31, thereby retaining the base 31 in the slag collecting box 2 and improving the operational stability of the slag basket assembly. A slag outlet 22 is defined on the bottom wall of the slag collecting box 2. Correspondingly, a slag outlet 312 is defined on the base 31 for the slag basket 32 ​​to discharge from the outlet 22, facilitating slag and water discharge.

[0031] The cleaning machine of this embodiment also includes a driving mechanism 4 for driving the base 31 to move up and down. The driving mechanism 4 is arranged at the bottom of the slag collecting box 2 and partially passes through the bottom wall of the slag collecting box 2 to be connected to the base 31. The driving mechanism 4 includes a motor 41, a screw rod 42 and a nut pair 43. The nut pair 43 is arranged on the base 31. The screw rod 42 is arranged vertically and the upper end is connected to the nut pair 43 and the lower end is connected to the output shaft of the motor 41. The motor 41 is arranged at the bottom of the slag collecting box 2 and is used to drive the screw rod 42 to rotate. The above-mentioned driving mechanism has a simple and reasonable structure, which is convenient for realizing stable driving of the slag basket. A protective cover 313 extending upward and used to accommodate the screw rod 42 is provided in the central part of the base 31. The nut pair 43 is provided at the lower end of the protective cover 313. This structure isolates the driving mechanism from the water environment to improve the reliability of the mechanism operation.

[0032] When the cleaning machine is finished cleaning once and needs to drain the slag, the driving mechanism 4 drives the base 31 to drive the slag basket 32 ​​to rise. When the slag basket 32 ​​rises to the slag inlet 322 and is located above the drain plate 12, the second sealing ring 200 on the outer edge of the support ring 323 cooperates closely with the slag collecting port 121 of the drain plate 12. The residue and waste water can enter the slag inlet 322 and further enter the slag collecting box 2, most of which are directly discharged through the slag port 312 and the slag outlet 22, and a small amount of residue remains in the slag basket; after the cleaning state or the slag collection is completed, the driving mechanism 4 drives the base 31 to drive the slag basket 32 ​​to fall, and the slag basket 32 ​​is lowered until it is completely hidden in the slag collecting box 2, and the end cover 321 on the top of the slag basket 32 ​​closes the upper end of the slag collecting box 2, thereby isolating the residue in the slag collecting box 2 to prevent the residue from overflowing upward from the slag collecting box 2, keeping the water flow of the secondary cleaning clean, and at the same time preventing the spread of odor.
