[0021] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0022] 1. An embodiment of the present invention provides a dishwasher, which includes a body, a cleaning space for cleaning dishes is provided inside, and a discharge outlet is provided on the body; a residue collector is provided at the bottom of the cleaning space and is provided with an opening facing the cleaning space; the residue collector has a collection position located at the bottom of the cleaning space and a cleaning position extending out of the discharge outlet under the drive of an external force.

[0023] With this arrangement, users do not need to pre-treat the food residue on the tableware before putting it in, and can directly put the tableware in, thereby reducing user operations and making it more convenient for users. After the dishwasher finishes cleaning the tableware, users do not need to clean the residue inside the dishwasher, but only need to pull the residue collector out of the discharge port and clean the food residue in the residue collector, which is convenient and saves trouble, optimizes the cleaning environment when users clean food residues, and improves the user experience.

[0024] 2. The present invention can prevent food residues in tableware from entering the washing pump during the washing process and the drainage pump during the drainage process by setting a filter, thereby avoiding the blockage of the washing pump and the drainage pump. In addition, since the filter is set above the open mouth of the residue collector, it can also play a certain guiding role for the food residues, guiding the food residues into the residue collector, thereby improving the collection efficiency of the residue collector.

[0025] 3. The present invention provides a bottom plate and a accommodating cavity in the residue collector so that food residues enter the accommodating cavity during the washing process, thereby preventing food residues and residual washing water from spilling or dripping when the residue collector moves toward the discharge port, thereby ensuring the hygiene and cleanliness of the dishwasher and the surrounding environment of the kitchen and improving the user experience.

[0026] 4. The present invention provides a piston pump and a receiving cavity suitable for the piston movement of the bottom plate. After washing is completed, the piston pump can be started to automatically move the bottom plate to the bottom of the receiving cavity, thereby preventing food residues and residual washing water from spilling or dripping during the outward movement of the residue collector, thereby ensuring the hygiene and cleanliness of the dishwasher and the surrounding environment of the kitchen, and improving the user experience.

[0027] 5. The present invention can collect food residues on the plastic film by providing the first roller and the second roller, and the plastic film rolled on the first roller. When the piston pump moves the bottom plate to the bottom of the accommodating chamber, the plastic film is tightly fitted with the bottom plate, so that the plastic film is sucked into the accommodating chamber at the same time, thereby better collecting food residues and residual water, preventing corrosion of the piston pump, and extending the life of the piston pump. In addition, the design of the first roller and the second roller can also facilitate users to lay plastic film on the bottom plate and replace plastic film, thereby simplifying user operations and improving user experience.

[0028] 6. The present invention provides a first drive motor and a plastic film traction head, and connects the drive shaft of the first drive motor to the second roller, so that the plastic film can remain stable during the process of collecting food residues, and prevent the plastic film from detaching from the second roller, thereby ensuring the normal operation of the residue collector. In addition, after the plastic film is sealed, the first drive motor can be driven to automatically replenish or replace the plastic film on the residue collector, without the need for manual replacement or replenishment, which simplifies user operations and improves the user experience.

[0029] 7. The present invention can seal the plastic film that has collected food residues and residual washing water by arranging a sealing device on the top of the residue collector, so that the food residues can be recovered together with the residual water after drainage. When the food residues are discharged, the washing water that cannot be completely drained is also recovered together, thereby improving the drying performance of the dishwasher. By arranging the sealing device, the user does not need to clean up, and only needs to throw the sealed plastic film into the trash can, which simplifies the user's operation process, optimizes the user's experience, and improves the user's experience.

[0030] 8. The present invention provides a driving device and a control device. After the dishwasher completes the cleaning task, the control device automatically controls the driving device to drive the residue collector to the discharge port, thereby eliminating the need for the user to manually pull the residue collector out of the discharge port, reducing the user's operation process, facilitating the user's cleaning, saving time and effort, and thus greatly optimizing the user's experience. It can also prevent the user from not cleaning in time, thereby causing food residues to breed bacteria, causing secondary contamination of tableware, and affecting the user's health.

[0031] 9. The present invention can seal the discharge port by providing a cover plate, so that the dishwasher remains in a closed state, ensuring that there is no odor emanating from the inside of the dishwasher in the kitchen, thereby improving the use environment of the kitchen and optimizing the user experience.

[0032] 10. The present invention connects the cover plate to the fourth drive motor, so that the opening and closing process of the cover plate can be fully automated, thereby further improving the performance of the dishwasher, optimizing the user's feeling, and enhancing the user's experience.

[0044] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] In the prior art, when a user uses a dishwasher, each time after the dishwasher cleans the dishes, the user needs to remove the food residues on the dishwasher filter to ensure the cleanliness and hygiene of the inside of the dishwasher. In order to reduce the number of times the user cleans the food residues, the dishwashers currently sold on the market require the user to manually remove the food residues on the dishes before putting them into the dishwasher for cleaning. However, after the dishwasher finishes cleaning the dishes each time, there will inevitably be food residues. And these food residues need to be cleaned manually by the user, which makes the operation and process of the user too cumbersome when cleaning the food residues, and the cleaning environment is poor, which affects the user's mood and brings a bad experience to the user, and does not achieve the expected use effect of the user. A dishwasher provided by the present invention can solve the problem that the food residues of the dishwasher in the prior art need to be cleaned by the user, which makes the user's operation too cumbersome.

[0049] like Figure 1-Figure 6The embodiment of the present invention provides a dishwasher, which includes a body 1 and a residue collector 2. A cleaning space 15 for washing dishes is provided inside the body 1, and the residue collector 2 is provided at the bottom of the cleaning space and is also provided with an open structure facing the cleaning space. The residue collector 2 has two working positions during operation, one is a position for collecting food residues at the bottom of the cleaning space, and the other is a cleaning position that can extend out of the discharge port 14 of the body 1 under the drive of an external force.

[0050] With such a configuration, before putting in the tableware, the user does not need to pre-treat the food residue on the tableware, and can directly put the tableware in, thereby reducing the user's operation and making it convenient for the user to use. After the dishwasher finishes cleaning the tableware, the user does not need to clean the residue inside the dishwasher, but only needs to manually pull the residue collector 2 out of the discharge port 14, and then clean the food residue in the residue collector 2. In order to ensure the cleanliness of the residue collector 2, the user can also clean the residue collector 2, which is convenient and saves trouble. The cleaning environment when the user cleans the food residue is optimized, and the user experience is improved.

[0051] Specifically, the discharge port 14 can be arranged inside the body 1, or can extend to the outside of the body 1. As a preferred embodiment, the discharge port 14 is arranged at a position close to the side wall below the body 1, and the height of the discharge port 14 is higher than the height of the residue collector 2, so as to ensure that the residues in the residue collector 2 can be collected.

[0052] In the embodiment of the present invention, the dishwasher further comprises a filter screen 11, which is suitable for covering the water inlet of the drainage pump 12 and the water inlet of the washing pump 13 in the body. Figure 1 As shown, the filter screen 11 is a cylindrical structure. The upper opening of the filter screen 11 is a residue inlet, and the lower opening of the filter screen 11 is a residue outlet, which is used to guide food residues to a residue collector.

[0053] Of course, as another implementation, the filter 11 can also be in other shapes, such as a regular polygon, an irregular polygon, etc. Those skilled in the art can change the shape and setting position of the filter 11 according to actual conditions. This is not limited in the present embodiment, as long as the same technical effect can be achieved.

[0054] The present invention provides a filter screen 11, and the water entering the filter screen 11 will seep into the drainage pump 12 and the washing pump 13, and the remaining solid residue will fall into the residue collector 2, which can prevent the food residue in the tableware from entering the washing pump during the cleaning process, and can also prevent the food residue from entering the drainage pump during the drainage process, thereby avoiding the clogging of the washing pump and the drainage pump. In addition, since the filter screen is provided above the opening of the residue collector, it can also play a certain guiding role for the food residue, guiding the food residue to enter the residue collector, thereby improving the collection efficiency of the residue collector.

[0055] In the embodiment of the present invention, Figure 1 and Figure 5 As shown, the residue collector 2 includes a bottom plate 21 and a receiving cavity 24, wherein the bottom plate 21 is disposed in the receiving cavity 24, and the receiving cavity 24 is provided with the above-mentioned open structure. In this way, food residues can enter the receiving cavity 24 during the washing process, thereby preventing food residues and residual washing water from spilling or dripping during the movement of the residue collector toward the discharge port, thereby ensuring the hygiene and cleanliness of the dishwasher and the surrounding environment of the kitchen, and improving the user experience.

[0056] The residue collector 2 is sealed and connected to the bottom of the cleaning space 15 through a seal. Of course, the sealing connection can be achieved by various technical measures, such as setting a sealing strip at the bottom of the cleaning space 15. This embodiment is only an example and does not limit the sealing method. Those skilled in the art can change it according to actual conditions.

[0057] In the embodiment of the present invention, a piston pump 22 is further provided at the bottom of the residue collector 2, the bottom plate 21 is connected to a piston rod 221 of the piston pump 22, and the piston pump 22 is electrically connected to the control device. After washing is completed, the user starts the piston pump 22 through the control device to move the bottom plate 21 to the bottom of the accommodating cavity 24, so that the food residues are collected in the accommodating cavity 24.

[0058] In this way, food residues and residual washing water can be prevented from spilling or dripping during the outward movement of the residue collector 2, thereby ensuring the hygiene and cleanliness of the dishwasher and the surrounding environment of the kitchen and improving the user experience.

[0059] After the user has finished cleaning the residue collector 2, the control device controls the piston pump 22 to move the bottom plate 21 upward to the open position of the accommodating chamber 24, so that the residue collector 2 is in a state ready to collect residues.

[0060] In the embodiment of the present invention, a first roller 3 and a second roller 4 are respectively provided on both sides of the residue collector 2, a plastic film receiving portion is provided on one of the first roller 3 and the second roller 4, and a plastic film pulling head is provided on the other of the first roller 3 and the second roller 4. The embodiment of the present invention is described by taking the first roller 3 being provided with a plastic film receiving portion and the second roller 4 being provided with a plastic film pulling head as an example.

[0061] When the residue collector 2 does not start to collect food residues, the residue collector 2 presses the plastic film 6 with the side wall to seal the cleaning space 15. When the residue collector 2 starts to collect food residues, the piston pump 22 controls the bottom plate 21 to move downward, at which time, the atmospheric pressure squeezes and deforms the plastic film 6 to fit the accommodating cavity 24 to collect food residues.

[0062] It should be noted here that the plastic film 6 is in an unfolded state before starting to collect food residues. When the piston pump 22 moves the bottom plate 21 to the bottom of the accommodating chamber 24, the plastic film 6 unfolds to form a food residue space.

[0063] The present invention can collect food residues on the plastic film 6 by providing the first roller 3 and the second roller 4, and the plastic film 6 rolled on the first roller 3. When the piston pump 22 moves the bottom plate 21 to the bottom of the accommodating chamber 24, the plastic film 6 is closely attached to the bottom plate 21, so that the plastic film 6 is simultaneously sucked into the accommodating chamber 24. Due to the presence of the plastic film 6, food residues and residual water can be better collected to prevent corrosion of the piston pump 22, thereby extending the life of the piston pump 22. In addition, the design of the first roller 3 and the second roller 4 can also facilitate users to lay the plastic film 6 on the bottom plate 21 and replace the plastic film 6. After the plastic film 6 is used up, the user can directly cover the rolled plastic film 6 on the first roller 3, and fix one end of the plastic film 6 on the second roller 4. This simplifies the user operation and improves the user experience.

[0064] The residue collector 2 is also provided with a first drive motor, a drive shaft of the first drive motor is connected to the second roller 4, and the first drive motor is electrically connected to the control device.

[0065] Of course, when the plastic film traction head is arranged on the first roller 3 , the driving shaft of the first driving motor of the second roller 4 is connected to the first roller 3 .

[0066] The present invention provides a first drive motor and a plastic film traction head, and connects the drive shaft of the first drive motor to the second roller 4, so that the plastic film 6 can be kept stable during the process of collecting food residues, and the plastic film 6 is prevented from being separated from the second roller 4, thereby ensuring the normal operation of the residue collector 2. In addition, the plastic film 6 can be automatically replenished or replaced on the residue collector 2 by driving the first drive motor, without the need for manual replacement or replenishment, which simplifies user operation and improves the user experience.

[0067] In order to prevent the residue from entering the plastic film 6 and then spilling, Figure 4 and Figure 6 As shown, the open position of the residue collector 2 is provided with a sealing device 23 that cooperates with the plastic film 6 and is used to seal the plastic film 6 in the residue collector 2. The sealing device 23 includes two second drive motors 231 respectively arranged on both sides of the residue collector 2 and two heating rods 232 arranged opposite to each other. The heating rods 232 are sleeved on the driving shaft of the second drive motor 231 through first through holes opened at both ends. The heating rods 232 have a sealing position close to each other and a completion position far away from each other under the drive of the second drive motor.

[0068] As a preferred embodiment, a first thread is provided at one end of the drive shaft close to the second drive motor 231, and a second thread is provided at the end away from the second drive motor 231. The first thread is connected to the second thread and has opposite rotation directions. A third thread that cooperates with the first thread and the second thread is provided on the inner side of the first through hole.

[0069] When the sealing device 23 is started, the two second drive motors 231 work simultaneously. Since the first thread and the second thread rotate in opposite directions, the two heating rods 232 are brought close to each other. When the two are in contact, the plastic film 6 in the open position is sealed. When the sealing is completed, the two second drive motors operate in the opposite direction, so that the two heating rods 232 move away from each other and reach the completion position.

[0070] It should be noted here that after the plastic film 6 is sealed, the plastic film 6 is not broken between the first roller 3 and the second roller 4, but a hole is formed at the position that fits with the open position of the accommodating cavity 24, so that the plastic film 6 can be automatically replenished or replaced on the residue collector 2 by driving the first drive motor.

[0071] The present invention can seal the plastic film 6 that has collected food residues and residual washing water by setting a sealing device 23 on the top of the residue collector 2, so that the food residues can be recovered together with the residual water after drainage. When the food residues are discharged, the washing water that cannot be completely drained is also recovered, thereby improving the drying performance of the dishwasher. By setting the sealing device 23, the user does not need to clean up, and only needs to throw the sealed plastic film 6 into the trash can, which simplifies the user's operation process, optimizes the user's use experience, and improves the user's use experience.

[0072] As another implementation, it is sufficient to set the first thread and the second thread on the driving shaft of one second driving motor, and the driving shaft of the other second driving motor can be replaced with a smooth rod with the same diameter.

[0073] As another embodiment, the sealing device 23 may further include two first push rod motors arranged opposite to each other and a heating rod 232 connected to the telescopic rod of the first push rod motor. The heating rod 232 has a sealing position close to each other and a completion position far away from each other under the drive of the first push rod motor.

[0074] In an embodiment of the present invention, the body 1 is further provided with a driving device and a control device, the driving device is connected to the residue collector 2, and the control device is electrically connected to the driving device. By providing the driving device and the control device, after the dishwasher completes the cleaning task, the control device automatically controls the driving device to drive the residue collector 2 to the discharge port 14 under its own action. The user only needs to clean the food residue in the residue collector 2, so that the user does not need to manually pull the residue collector 2 out of the discharge port 14, which reduces the user's operation process, facilitates the user's cleaning, saves time and effort, and greatly optimizes the user's experience.

[0075] In the prior art, some users do not clean the food residue inside the dishwasher after the dishwasher completes the cleaning task, which causes bacteria to grow inside the dishwasher, affecting the user's use. The present invention provides a driving device and a control device. After the dishwasher completes the cleaning task, the control device automatically controls the driving device to drive the residue collector 2 to the discharge port 14 under its own action. The user can thus directly clean the food residue, thereby preventing the user from not cleaning in time, causing the food residue to breed bacteria, causing secondary contamination of the tableware, and affecting the user's health.

[0076] After the user has finished cleaning the residue collector 2, the user can control the driving device through the control device to directly drive the residue collector 2 to the collection position, which is convenient and saves trouble.

[0077] In the embodiment of the present invention, the driving device may be a screw motor 7 and a threaded screw 5 that cooperates with the screw motor 7. The screw motor 7 is disposed at the bottom of the body 1, and the residue collector 2 is connected to the threaded screw 5. When the driving device drives the residue collector 2, the screw motor 7 can directly move the residue collector 2 to the discharge port 14 through the threaded screw 5. Then, the control device controls the screw motor 7 to move the residue collector 2 to the collection position through the threaded screw 5.

[0078] Of course, as another embodiment, the driving device can also be a push rod motor and a telescopic rod working with the push rod motor, and the telescopic rod is electrically connected to the residue collector 2. The specific operation process is not repeated here, and the working process of the screw motor 7 is referred to.

[0079] In this embodiment, the body 1 is provided with a cover plate suitable for closing the discharge port 14, and the cover plate is rotatably connected to the body 1. By providing the cover plate, the discharge port 14 can be closed, so that the dishwasher remains in a closed state, ensuring that there is no odor emitted from the inside of the dishwasher in the kitchen, thereby improving the use environment of the kitchen and optimizing the user experience.

[0080] Of course, the body 1 is also provided with a fourth drive motor, the cover is connected to the drive shaft of the fourth drive motor, and the fourth drive motor is electrically connected to the control device. By connecting the cover to the fourth drive motor, the opening and closing process of the cover can be fully automated, further improving the performance of the dishwasher, optimizing the user's experience, and enhancing the user's experience.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
