Abstract
Description
Technical Field
[0001] This utility model relates to the field of dishwasher technology, specifically to a washing machine for cleaning tableware, fruits and vegetables. Background Technology
[0002] Currently, most dishwashers on the market generally include a cabinet and a spray device located in the cabinet. The spray device is used to draw water from the bottom of the cabinet into the spray component and spray it into the washing chamber to rinse the dishes.
[0003] The applicant's earlier application CN202011635836.0, "A Cleaning Machine and its Partition Drive Component Installation Method," discloses a structure comprising: a housing having an inner cavity; a partition assembly disposed within the inner cavity of the housing for dividing the inner cavity of the housing into relatively independent upper and lower spaces; the partition assembly comprising: a fixed plate horizontally disposed in the middle of the housing and connected to the inner side wall of the housing; and a movable plate movably disposed on the fixed plate for cooperating with the fixed plate to separate the upper and lower spaces or connect the upper and lower spaces.
[0004] The above solution incorporates a partition assembly within the cabinet that divides the cabinet into relatively independent upper and lower spaces. When the number of dishes to be washed is small, the movable plate of the partition assembly moves relative to the fixed plate, separating the upper and lower spaces. The upper space can be used to place the washed dishes, while the lower space can be sprayed for cleaning independently. This not only makes full use of the cabinet space but also helps save energy such as water and electricity. When the number of dishes to be washed is large, the movable plate of the partition assembly moves relative to the fixed plate, connecting the upper and lower spaces and simultaneously cleaning the dishes in both spaces. This invention can adjust the cleaning space according to the number of dishes to be washed, thereby meeting the needs of more consumers.
[0005] However, in the above solution, the partition assembly is horizontally positioned in the middle of the washing chamber. Regardless of whether the partition assembly is extended or retracted, at least half of it rests in the center of the washing chamber, which makes it easy for residual water to remain on the partition. Furthermore, the partition assembly obstructs the spray water column to a certain extent, thus affecting the washing effect. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a cleaning machine that can eliminate residual water on the partition and improve the cleaning effect, in light of the current state of the technology.
[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0008] A washing machine includes a housing having a laterally extending washing chamber. A partition assembly is provided at the center of the washing chamber to divide it into a relatively independent left chamber and a right chamber. The rear end of the partition assembly is constrained to the rear side wall of the washing chamber. The partition assembly includes multiple retractable baffles. When the partition assembly is extended, it separates the left chamber and the right chamber. When the partition assembly is retracted, it forms a washing chamber that runs through the left and right sides.
[0009] By adopting the above structure, the washing machine housing is designed as a washing chamber with a large horizontal length, and a vertically arranged partition assembly is installed in the washing chamber. This structure does not affect the height of the washing chamber whether the partition is used or not, and can accommodate taller tableware to meet more consumer needs. Moreover, the vertical part of the partition assembly is relatively short after it is retracted, which is conducive to the rapid drainage of residual water, achieving a water-free partition. In the extended state, the partition assembly will not obstruct the upward water jet, which helps to improve the cleaning effect.
[0010] Preferably, the baffle assembly includes at least a first baffle, a second baffle, and a third baffle. The first baffle is formed into a U-shaped structure with its opening facing forward, and the closed end of the U-shaped structure of the first baffle is located near the rear sidewall of the washing chamber. The second baffle is also formed into a U-shaped structure with its opening facing forward, and the closed end of the U-shaped structure of the second baffle can be inserted back and forth into the inner cavity of the U-shaped structure of the first baffle. The rear end of the third baffle can be inserted back and forth into the inner cavity of the U-shaped structure of the second baffle. This structure facilitates the forward and backward extension and retraction of each baffle, and the sides of the baffle assembly maintain good flatness regardless of whether the baffles are extended or retracted, preventing residue from adhering to the walls and achieving good flow guidance.
[0011] Preferably, limiting structures are provided between the front end of the first baffle and the rear end of the second baffle, and between the front end of the second baffle and the rear end of the third baffle, to limit the movement of each baffle when the partition assembly is extended. Specifically, the limiting structures are as follows: a first rib is provided on the front end side of the rear baffle, and a second rib is provided on the rear end side of the front baffle; the first and second ribs are staggered and engaged to limit movement. This structure ensures that the baffles will not detach from each other when extended.
[0012] Preferably, the side walls of the first baffle partially protrude outward to form a first guide groove extending forward and backward, the side walls of the second baffle partially protrude outward to form a second guide groove extending forward and backward, and the outer side wall of the second baffle corresponding to the second guide groove forms a first guide rail that can guide and cooperate with the first guide groove. The side walls of the third baffle partially protrude outward to form a second guide rail that extends forward and backward and can guide and cooperate with the second guide groove. This structure, on the one hand, can guide the expansion and contraction of the partition assembly, improving the stability of forward and backward expansion and contraction; on the other hand, it facilitates limiting and storage, improving the reliability of the expansion and contraction of the partition assembly.
[0013] Preferably, the partition assembly further includes a fourth baffle and a fifth baffle. The third and fourth baffles are also formed into U-shaped structures with their openings facing forward. The closed end of the U-shaped structure of the fourth baffle is movable back and forth and inserted into the inner cavity of the U-shaped structure of the third baffle. The fifth baffle is a solid plate, and its rear end is movable back and forth and inserted into the inner cavity of the U-shaped structure of the fourth baffle. By using multiple baffles for telescopic cooperation, the front-to-back width of the partition assembly in the retracted state can be reduced, allowing the left and right cavities to be fully connected.
[0014] In this invention, the housing is equipped with a drive assembly for extending and retracting the partition assembly, and the drive end of the drive assembly is connected to the side wall of the fifth baffle. This structure facilitates the automatic extension and retraction of the partition assembly.
[0015] Preferably, in the retracted state, the second baffle is hidden within the first baffle, the third baffle is hidden within the second baffle, the fourth baffle is hidden within the third baffle, and a portion of the fifth baffle is partially hidden within the fourth baffle. The portion of the fifth baffle exposed outside the fourth baffle, together with the first baffle, forms a fixed plate structure vertically placed at the rear of the washing chamber. With this structure, when the left and right chambers are connected, the water volume of the spray jet is larger, and the front-to-back width of the fixed plate structure is smaller and the surface is flat, thereby reducing splashing and preventing wall adhesion.
[0016] Preferably, the drive assembly includes a motor, a transmission gear set, a lead screw, and a nut assembly. The motor is constrained to the rear side wall of the housing via a motor housing. The lead screw extends forward and backward near the side wall of the partition assembly, with its rear end rotatable, and is arranged through the motor housing. The output shaft of the motor is connected to the rear end of the lead screw via the transmission gear set. The nut assembly is constrained to the side wall of the fifth baffle and engages with the lead screw for transmission. This structure achieves automatic extension and retraction of the partition assembly through simple assembly.
[0017] This utility model also includes an installation frame, whose inner top and bottom walls are respectively provided with sliding grooves. The partition assembly is movably disposed in the installation frame, with its upper and lower ends respectively engaging with the corresponding sliding grooves. The partition assembly and the installation frame constitute an integral installation module. The bottom wall of the housing is provided with a front-to-back extending installation platform, on which the integral installation module is disposed. This structure not only improves the sealing shape and stability of the partition assembly during front-to-back expansion and contraction, but also facilitates the assembly and installation of the integral installation module, simplifying production.
[0018] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets the washing machine housing into a washing chamber with a large horizontal length, and sets a vertically arranged partition assembly in the washing chamber. This structure does not affect the height of the washing chamber whether the partition is used or not, and can accommodate tall tableware to meet more consumer needs; moreover, the vertical part of the partition assembly is shorter after it is retracted, which is conducive to the rapid drainage of residual water, so that the partition is free of residual water. In the extended state, the partition assembly will not block the water jet from bottom to top, which is conducive to improving the cleaning effect. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] like Figures 1-5As shown, the washing machine of this embodiment includes a housing 1, which forms a laterally extending washing chamber. A partition assembly 2 is provided in the central part of the washing chamber, which can divide it into a relatively independent left chamber 11 and a right chamber 22. The rear end of the partition assembly 2 is constrained to the rear side wall of the washing chamber. The partition assembly 2 includes multiple baffles that can extend and retract back and forth. When the partition assembly 2 is extended, it is used to separate the left chamber 11 and the right chamber 22. When the partition assembly 2 is retracted, it is used to form a washing chamber that runs through the left and right sides.
[0026] With the above structure, the washing machine housing 1 is set as a washing chamber with a large horizontal length, and a vertically arranged partition assembly is set in the washing chamber. This structure does not affect the height of the washing chamber whether the partition is used or not, and can accommodate tall tableware to meet more consumer needs. Moreover, the vertical part of the partition assembly 2 is short after it is retracted, which is conducive to the rapid drainage of residual water, so that the partition is free of residual water. When the partition assembly 2 is extended, it will not block the water jet from bottom to top, which helps to improve the cleaning effect.
[0027] The baffle assembly 2 includes at least a first baffle 21, a second baffle 22, and a third baffle 23. The first baffle 21 is formed into a U-shaped structure with its opening facing forward. The closed end of the U-shaped structure of the first baffle 21 is located near the rear side wall of the washing chamber. The second baffle 22 is also formed into a U-shaped structure with its opening facing forward. The closed end of the U-shaped structure of the second baffle 22 can be inserted back and forth into the inner cavity of the U-shaped structure of the first baffle 21. The rear end of the third baffle 23 can be inserted back and forth into the inner cavity of the U-shaped structure of the second baffle 22. With the above structure, it is easy to realize the back and forth extension and retraction of each baffle. Whether the baffle is extended or retracted, the side of the baffle assembly can maintain good flatness, avoid residue sticking to the wall, and achieve good flow guidance.
[0028] A limiting structure is provided between the front end of the first baffle 21 and the rear end of the second baffle 22, and between the front end of the second baffle 22 and the rear end of the third baffle 23, to limit the movement of each baffle when the partition assembly 2 is extended. Specifically, the limiting structure consists of a first rib 001 on the front side of the rear baffle and a second rib 002 on the rear side of the front baffle, with the first rib 001 and the second rib 002 interlocking for limiting movement. This structure ensures that the baffles do not detach from each other when extended.
[0029] The first baffle 21 has its side walls partially protruding outward to form a first guide groove 211 extending forward and backward. The second baffle 22 has its side walls partially protruding outward to form a second guide groove 221 extending forward and backward. The outer side wall of the second baffle 22 corresponding to the second guide groove 221 forms a first guide rail 222 that can guide and cooperate with the first guide groove 211. The third baffle 23 has its side walls partially protruding outward to form a second guide rail 231 extending forward and backward and capable of guiding and cooperating with the second guide groove 221. This structure, on the one hand, guides the expansion and contraction of the partition assembly, improving the stability of forward and backward expansion and contraction; on the other hand, it facilitates limiting and storage, improving the reliability of the expansion and contraction of the partition assembly.
[0030] The partition assembly 2 also includes a fourth baffle 24 and a fifth baffle 25. The third baffle 23 and the fourth baffle 24 are also formed into U-shaped structures with their openings facing forward. The closed end of the U-shaped structure of the fourth baffle 24 can be inserted back and forth into the inner cavity of the U-shaped structure of the third baffle 23. The fifth baffle 25 is a solid plate, and its rear end can be inserted back and forth into the inner cavity of the U-shaped structure of the fourth baffle 24. Adjacent baffles are limited by limiting structures. By using multiple baffles for telescopic cooperation, the front and rear width of the partition assembly 2 in the contracted state can be reduced, so that the left and right cavities 22 can be fully connected.
[0031] In this embodiment, the housing 1 is provided with a drive assembly 3 for driving the expansion and contraction of the partition assembly. The drive end of the drive assembly is connected to the side wall of the fifth baffle 25. This structure facilitates the automatic expansion and contraction of the partition assembly.
[0032] In the retracted state, the second baffle 22 is concealed within the first baffle 21, the third baffle 23 is concealed within the second baffle 22, the fourth baffle 24 is concealed within the third baffle 23, and a portion of the fifth baffle 25 is partially concealed within the fourth baffle 24. The portion of the fifth baffle 25 exposed outside the fourth baffle 24, together with the first baffle 21, forms a vertically positioned fixed plate structure at the rear of the washing chamber. With this structure, when the left and right cavities 22 are connected, the water volume of the spray jet is relatively large, and the front-to-back width of the fixed plate structure is small with a flat surface, thus reducing splashing and preventing wall adhesion.
[0033] The drive assembly 3 includes a motor 31, a transmission gear set 32, a lead screw 33, and a nut assembly 34. The motor 31 is constrained to the rear side wall of the housing 1 by a motor box 35. The lead screw 33 extends forward and backward near the side wall of the partition assembly, with its rear end rotatable, and is arranged through the motor box 35. The output shaft of the motor 31 is connected to the rear end of the lead screw 33 via the transmission gear set 32. The nut assembly 34 is constrained to the side wall of the fifth baffle 25 and cooperates with the lead screw 33 for transmission. This structure achieves automatic extension and retraction of the partition assembly through simple cooperation.
[0034] This embodiment also includes an installation frame 5. The inner top wall of the installation frame 5 has a sliding groove 51, and the inner bottom wall has a sliding rail 52. The partition assembly 2 is movably disposed within the installation frame 5, with its upper end engaging with the sliding groove 51 and its lower end engaging with the sliding rail 52. The partition assembly 2 and the installation frame 5 constitute an integral installation module. The inner bottom wall of the housing 1 is provided with a front-to-back extending mounting platform 13, on which the integral installation module is disposed. This structure not only improves the sealing shape and stability of the partition assembly during front-to-back expansion and contraction but also facilitates the assembly and installation of the integral installation module, simplifying production.
[0035] In this embodiment, the washing machine housing 1 is configured as a washing chamber with a large horizontal length, and a vertically arranged partition assembly is installed in the washing chamber. This structure does not affect the height of the washing chamber whether the partition is used or not, and can accommodate tall tableware to meet more consumer needs. Moreover, the vertical part of the partition assembly 2 is relatively short after it is retracted, which is conducive to the rapid drainage of residual water, so that the partition is free of residual water. When the partition assembly 2 is extended, it will not block the water jet from bottom to top, which helps to improve the cleaning effect.
