Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a partition assembly for a dishwasher and a dishwasher. Background Technology

[0002] Currently, most dishwashers on the market generally consist of a cabinet and a spray system located within the cabinet. The spray system draws water from the bottom of the cabinet into a spray nozzle and sprays it into the washing chamber to rinse the dishes. The washing chamber volume of most dishwashers is fixed and cannot be adjusted according to the amount of dishes to be washed. When the number of dishes to be washed is small, placing them in a large washing chamber not only affects the washing effect but also wastes water.

[0003] In addition, for some large-capacity dishwashers, users are used to storing the dishes inside the dishwasher after washing. In this case, if the number of dishes used per meal is small, the stored dishes need to be washed together with the dishes the next time, which will also waste water and electricity.

[0004] To address the aforementioned issues, Chinese invention patent application CN202011635836.0 (publication number CN114680781A) discloses a dishwasher and its partition drive assembly, entitled "Installation Method of a Dishwasher and its Partition Drive Component." The dishwasher includes: a cabinet with an inner cavity; a partition assembly disposed within the inner cavity to divide the inner cavity into relatively independent upper and lower spaces; the partition assembly includes: a fixed plate horizontally positioned in the middle of the cabinet and connected to the inner wall of the cabinet; a movable plate movably disposed on the fixed plate for cooperating with the fixed plate to separate or connect the upper and lower spaces; and a surrounding plate disposed on the lower wall of the fixed plate, forming a relatively independent mounting compartment with the inner wall of the cabinet; and a drive component disposed in the mounting compartment, with a power output shaft passing through the surrounding plate and connected to the movable plate. The drive component is a motor, and at least the front part of the power output shaft is a screw, with the movable plate connected to the screw via a nut pair.

[0005] 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 and lower spaces, which is the half-cavity washing state. The upper space can be used to place the washed dishes, and the lower space can be sprayed for washing separately. This not only makes full use of the cabinet space, but also helps to save 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 to connect the upper and lower spaces, which is the full-cavity washing state. The dishes in the upper and lower spaces are washed at the same time.

[0006] The structure of the partition assembly in the aforementioned patent has a fixed plate that is always horizontally placed in the cabinet. During full-cavity washing, the fixed plate will block the water flow, affecting the rinsing effect. Furthermore, the fixed plate and the movable plate are thick, which affects the placement of tableware.

[0007] As can be seen from the above, regardless of whether it is a full-cavity wash or a separate-cavity wash, the partition assembly occupies a large space inside the cabinet. In addition, the drive unit is always placed horizontally in the cabinet, which also takes up a lot of space, affects the appearance, and is easily affected by contaminants from tableware. Utility Model Content

[0008] The first technical problem to be solved by this utility model is to provide a partition assembly for a dishwasher that occupies little space during full-cavity washing, in light of the current state of the technology.

[0009] The second technical problem to be solved by this utility model is to provide a dishwasher that uses the above-mentioned partition assembly, in view of the current state of the prior art.

[0010] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a partition assembly for a dishwasher, characterized in that it includes...

[0011] A scroll that extends in the left-right direction and can rotate about its axis;

[0012] A flexible partition can be wound onto a spool. The flexible partition can move forward and backward from its extended end on the spool to a first position and a second position. When the extended end of the flexible partition is moved forward to the first position, the flexible partition is used to divide the interior of the dishwasher into an independent upper space and a lower space. When the extended end of the flexible partition is moved backward to the second position, the flexible partition is wound onto the spool, and the upper space and the lower space are connected.

[0013] A fixing strip extends in the left-right direction and is located at the protruding end of the flexible partition;

[0014] The guide rail extends in the front-to-back direction, and there are two guide rails located on the left and right sides of the flexible partition, respectively.

[0015] Drive mechanism, including

[0016] Drive components;

[0017] Two pull ropes are installed in the guide rail and can move back and forth respectively. The first end of one pull rope is connected to the left end of the fixed bar and the second end is connected to the drive component. The first end of the other pull rope is connected to the right end of the fixed bar and the second end is also connected to the drive component.

[0018] An elastic element acts on the reel, causing the reel to maintain its tendency to rotate with the flexible partition wound around it.

[0019] The drive mechanism can be directly connected to the two pull ropes, such as a dual-output shaft motor, or the drive mechanism can be connected to the pull ropes through a transmission structure.

[0020] The transmission structure can have various structural forms. A simpler structure includes a worm gear and a worm. The second ends of both pull ropes are connected to worms extending in the left-right direction. These two worms are spaced apart vertically. The worm gear is located between the two worms and is driven by a driving component. The rotation axis of the worm gear extends in the front-back direction. The transmission structure of this application achieves the movement of the two pull ropes through the cooperation of the two worms and the worm gear, resulting in a simple and compact structure.

[0021] To prevent dirt and grime from contaminating the drive mechanism, a housing is provided at the rear of the roll, and the drive components and transmission structure are all housed within this housing. This way, the entire drive mechanism is concealed within the housing and guide rails, reducing the probability of contamination and improving the overall aesthetics of the dishwasher.

[0022] To ensure comprehensive sterilization and disinfection of tableware, a sterilization component is installed on the fixing strip. During the dishwasher drying process, the tableware on the upper rack in the upper space and the lower rack in the lower space of the dishwasher are dynamically sterilized and disinfected by the flexible partition extending and retracting back and forth, making the ultraviolet irradiation of the tableware on the upper and lower racks more uniform and shortening the light path of the sterilization component.

[0023] Preferably, the disinfection component is an ultraviolet lamp.

[0024] Preferably, the guide rail is provided with an air duct, the fixing strip has a hollow flow channel inside that communicates with the air duct, and the bottom and top walls of the fixing strip are provided with air outlets that communicate with the flow channel. During the dishwasher drying process, the flexible partition extends and retracts to dynamically blow hot air onto the dishes on the upper rack in the upper space and the lower rack in the lower space of the dishwasher, so that the dishes on the upper and lower racks are heated evenly, and the temperature field in the cabinet is more uniform.

[0025] Preferably, a camera is installed on the fixing strip. This allows the flexible partition to dynamically identify the degree of soiling on the dishes in the upper rack in the upper space and the lower rack in the lower space of the dishwasher during the washing process, thereby adjusting the washing time and program accordingly.

[0026] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a dishwasher, characterized in that it includes a cabinet with an open front, a door movably disposed at the open part of the cabinet, and the aforementioned partition assembly, wherein the roller is located at the rear of the cabinet, and the fixing strip abuts against the door when the door closes the cabinet.

[0027] Compared with the prior art, the advantages of this utility model are as follows: By setting a flexible partition, when full-cavity washing is required, the flexible partition is wound onto a roller with the roller adjacent to the rear side wall of the cabinet. In this way, the flexible partition is located on the rear side wall of the cabinet, occupying little space, achieving the largest possible compartment, not affecting the placement of tableware, and not obstructing the water flow. When half-cavity washing is required, the extended end of the flexible partition is pulled to the first position, separating the upper and lower spaces, allowing tableware to be washed in the lower space and stored in the upper space.

[0028] In addition, this utility model is equipped with guide rails on both the left and right sides, and two pull ropes are respectively connected to the left and right ends of the fixing strip, so that the flexible partition is subjected to uniform force during the movement.

[0040] Example 1

[0041] like Figures 1-8 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a door and a partition assembly. The front of the cabinet 1 is open, and the door is movably disposed at the opening of the cabinet 1.

[0042] The partition assembly includes a roller 2, a flexible partition 3, a fixing strip 4, a guide rail 5, a drive mechanism 6, and a receiving box 7. In this embodiment, the flexible partition 3 is made of a single layer of flexible material with a thickness of 0.8 to 1.5 mm, such as umbrella fabric.

[0043] The roller 2 is located at the rear of the housing 1. The roller 2 extends in the left and right direction and can rotate around its axis. The fixing strip 4 extends in the left and right direction and is located at the protruding end of the flexible partition 3. When the door closes the housing 1, the fixing strip 4 abuts against the door. The front wall of the fixing strip 4 can be made of flexible materials such as silicone or rubber to ensure its sealing with the door and prevent water leakage between the upper space 11 and the lower space 12.

[0044] The flexible partition 3 can be wound around the roller 2. The flexible partition 3 can move back and forth from the extended end on the roller 2 to a first position and a second position. When the extended end of the flexible partition 3 moves forward to the first position, the flexible partition 3 is used to divide the interior of the dishwasher body 1 into an independent upper space 11 and a lower space 12. When the extended end of the flexible partition 3 moves backward to the second position, the flexible partition 3 is wound around the roller 2, and the upper space 11 and the lower space 12 are connected.

[0045] When a full-cavity wash is required, the flexible partition 3 is wound onto the roller 2, with the roller 2 adjacent to the rear side wall of the cabinet 1. In this way, the flexible partition 3 is located on the rear side wall of the cabinet 1, occupying little space, achieving the largest possible cavity division, without affecting the placement of tableware, and without obstructing the water flow. When a half-cavity wash is required, the extended end of the flexible partition 3 is pulled to the first position, separating the upper space 11 and the lower space 12. This allows the tableware to be washed in the lower space 12 and stored in the upper space 11.

[0046] The drive mechanism 6 includes a drive component 61, a pull rope 62, and an elastic component 63. The guide rail 5 extends in the front-back direction. There are two guide rails 5, which are located on the left and right sides of the flexible partition 3, respectively. There are two pull ropes 62, which are respectively installed in the guide rails 5 on the corresponding sides and can move back and forth. The guide rail 5 guides the movement of the pull ropes 62, and the arrangement of the two pull ropes 62 makes the force on the flexible partition 3 uniform during the movement.

[0047] One of the pull ropes 62 has its first end connected to the left end of the fixing bar 4 and its second end connected to the driving member 61. The other pull rope 62 has its first end connected to the right end of the fixing bar 4 and its second end also connected to the driving member 61. The elastic member 63 acts on the reel 2, causing the reel 2 to maintain the tendency to rotate with the flexible partition 3 wound around it. In this embodiment, the elastic member 63 is a torsion spring, and a mounting shaft 21 can be provided in the reel 2, with the elastic member 63 fitted onto the mounting shaft 21. In this embodiment, both the left and right ends of the fixing bar 4 are provided with sliders 40, which can slide back and forth along the corresponding guide rails 5. The first end of one pull rope 62 is connected to the slider 40 on the left, and the first end of the other pull rope 62 is connected to the slider 40 on the right.

[0048] The drive mechanism 6 is connected to the pull rope 62 through a transmission structure. The transmission structure includes a worm wheel 64 and a worm 65. The second end of each of the two pull ropes 62 is connected to a worm 65 extending in the left-right direction. The two worms 65 are spaced apart in the vertical direction. The worm wheel 64 is located between the two worms 65 and is driven by the drive member 61. The rotation axis of the worm wheel 64 extends in the front-back direction.

[0049] The driving component 61 drives the worm gear 64 to rotate, causing the two worms 65 to move in opposite directions. The movement of the worms 65 drives the corresponding pull rope 62 to move, thereby pulling the flexible partition 3 to move back and forth. During the backward movement of the flexible partition 3, the roller 2 rotates under the action of the elastic component 63, thus winding the flexible partition 3 around it. During the forward movement of the flexible partition 3, the roller 2 rotates under the action of the friction of the flexible partition 3.

[0050] It should be noted that the material of the pull rope 62 must be able to deform, but also be able to move back and forth along the guide rail 5 under the action of the corresponding worm gear 65.

[0051] A receiving box 7 is provided on the rear side of the roller 2, and the drive component 61 and the transmission structure are all located in the receiving box 7. In this way, the entire drive mechanism 6 is hidden in the receiving box 7 and the guide rail 5, reducing the probability of contamination and improving the overall aesthetics of the dishwasher.

[0052] Example 2

[0053] like Figure 5 , 6 As shown, the difference between this embodiment and Embodiment 1 is that the fixing strip 4 is provided with a disinfection component 8. In this embodiment, the disinfection component 8 is an ultraviolet lamp.

[0054] During the drying process of the dishwasher, the flexible partition 3 extends and retracts to dynamically sterilize and disinfect the tableware on the upper rack of the upper space 11 and the lower rack of the lower space 12 of the dishwasher, making the ultraviolet irradiation of the tableware on the upper and lower racks more uniform and the light path of the disinfection component 8 shorter.

[0055] Example 3

[0056] The difference between Example 1 and Example 2 is as follows:

[0057] like Figure 7 , 8 As shown, this embodiment not only includes ultraviolet lamps, but also an air duct 51 within the guide rail 5. The fixing strip 4 has a hollow flow channel 41 connected to the air duct 51, and air outlets 42 connected to the flow channel 41 are provided on both the bottom and top walls of the fixing strip 4. During the dishwasher drying process, the flexible partition 3 extends and retracts to dynamically blow hot air onto the tableware on the upper rack in the upper space 11 and the lower rack in the lower space 12 of the dishwasher, ensuring that the tableware on the upper and lower racks is heated evenly, and simultaneously making the temperature field within the cabinet 1 more uniform. Furthermore, the tableware on the upper and lower racks is dynamically disinfected during the extension and retraction of the flexible partition 3.

[0058] Example 4

[0059] The difference between this embodiment and Embodiment 1 is that:

[0060] The fixing strip 4 is also equipped with a camera, so that during the dishwasher washing process, the flexible partition 3 can extend and retract to dynamically identify the degree of dirt on the dishes in the upper rack in the upper space 11 and the lower rack in the lower space 12 of the dishwasher, so as to adjust the washing time and washing program.

[0061] Example 5

[0062] It is a combination of at least one of Examples 2, 3, and 4.
