Description

Technical Field

[0001] This utility model relates to 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 utility model patent CN202023348649.2 (publication number CN215383808U) discloses a dishwasher, comprising: a cabinet having an inner cavity; a partition assembly disposed within the inner cavity of the cabinet for dividing 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 side 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; further comprising: a surrounding plate disposed on the lower wall of the fixed plate, forming a relatively independent mounting compartment between the surrounding plate and 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.

[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. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a dishwasher with a small partition space occupied in the full-cavity washing state, in light of the current state of the technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a dishwasher, comprising...

[0009] The box-shaped structure has an open front.

[0010] The partition assembly is located inside the enclosure;

[0011] The partition assembly is characterized in that it includes...

[0012] A scroll is located on the rear side wall of the housing, the scroll extends in the left-right direction and can rotate about its axis;

[0013] A flexible partition is wound on a spool. The flexible partition can move back and forth to a first position and a second position from its extended end on the spool. When the extended end of the flexible partition moves forward to the first position, the flexible partition divides the interior of the box into an independent upper space and a lower space. When the extended end of the flexible partition moves backward to the second position, the flexible partition is wound on the spool, and the upper space and the lower space are connected.

[0014] Drive mechanism, including

[0015] The driving component, connected to the spool drive, is used to drive the spool to rotate;

[0016] An elastic element acts on the flexible partition, causing the extended end of the flexible partition to maintain a forward-moving tendency.

[0017] The elastic element could be a simple telescopic spring, but even when compressed to its limit, it retains a certain length. This not only occupies significant space in the front-to-back direction but also prevents the flexible partition from being fully wound onto the spool, resulting in a large space requirement. Therefore, the elastic element includes a first tension spring, a second tension spring, and a spring sheet. A fixing member is fixedly installed near the spool in the housing. One end of the first tension spring is fixedly connected to the front end of the flexible partition, and the other end is fixedly connected to the first end of the spring sheet. One end of the second tension spring is fixedly connected to the fixing member, and the other end is fixedly connected to the second end of the spring sheet. When the flexible partition is in its first position, the spring sheet, the first tension spring, and the second tension spring form a triangular shape. During the backward pulling of the flexible partition, the spring sheet bends, causing the first and second tension springs to change from a front-to-back extension to a left-to-right extension. The overall space occupied by the elastic element in the housing is minimized, and the flexible partition is wound onto the spool as much as possible.

[0018] To position and guide the first tension spring, the second tension spring, and the spring sheet, the drive mechanism further includes a first connecting rod and a second connecting rod. The first tension spring is disposed in the first connecting rod, and the second tension spring is disposed in the second connecting rod. The first connecting rod and the second connecting rod are rotatably connected by a vertically extending pivot, and the spring sheet is located at the connection point of the first connecting rod and the second connecting rod. The first connecting rod and the second connecting rod serve the functions of positioning and guiding.

[0019] In order to better position and guide the spring, the inner wall surface of the second link adjacent to the first link has an arc-shaped structure that matches the spring, and the spring is partially attached to the arc-shaped structure.

[0020] In the above scheme, there are two sets of driving mechanisms, located on the left and right sides of the flexible partition, respectively, so that the flexible partition is subjected to uniform force on the left and right sides and moves smoothly.

[0021] If the elastic element is triangular and arched towards the side wall of the box, it may interfere with the side wall of the box during the process of pulling the flexible partition and bending the spring. Therefore, when the flexible partition is in the first position, the spring, the first tension spring and the second tension spring form a triangular shape that arches towards the side wall of the box away from the corresponding side. In this way, during the process of pulling the flexible partition and bending the spring, the spring drives the first tension spring and the second tension spring to move towards the inside of the box.

[0022] Preferably, the drive unit is located outside the housing, and the output shaft of the drive unit passes through the side wall of the housing and is connected to the reel drive. In this way, the drive unit not only does not occupy the space inside the housing, but also does not require waterproofing.

[0023] In the above scheme, in order to facilitate the positioning of the first tension spring, a fixing strip is fixedly provided at the front end of the flexible partition, and the front end of the first tension spring is connected to the fixing strip.

[0024] To improve the disinfection effect inside the box, the fixing strip is equipped with disinfection components. During the movement of the flexible partition, the box can be dynamically disinfected, reducing disinfection dead corners and achieving good disinfection results.

[0025] In the above solution, the disinfection component is an ultraviolet lamp, and the power cord connected to the ultraviolet lamp is partially passed through the first and second connecting rods. In this way, the power cord does not occupy additional space in the housing. After passing through the first and second connecting rods, the power cord is connected to the circuit board.

[0026] 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.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-6 As shown, the dishwasher of this preferred embodiment includes a cabinet 1 and a partition assembly. The front of the cabinet 1 is open, and the partition assembly is disposed in the cabinet 1.

[0035] The partition assembly includes a roller 2, a flexible partition 3, and a drive mechanism.

[0036] A scroll 2 is located on the rear side wall of the box body 1. The scroll 2 extends in the left-right direction and can rotate around its axis. A flexible partition 3 is wound around the scroll 2. The flexible partition 3 can move forward and backward from its extended end on the scroll 2 to a first position and a second position. When the extended end of the flexible partition 3 is moved forward to the first position, the flexible partition 3 divides the interior of the box body 1 into an independent upper space 11 and a lower space 12. When the extended end of the flexible partition 3 is moved backward to the second position, the flexible partition 3 is wound around the scroll 2, and the upper space 11 and the lower space 12 are connected. The flexible partition 3 can be made of a flexible and waterproof material, such as umbrella fabric, and the flexible partition 3 is relatively thin, so it has little impact on the placement of tableware.

[0037] The driving mechanism includes a driving component 4, an elastic component, a first connecting rod 61, and a second connecting rod 62. The driving component 4 is driven and connected to the roller 2 to drive the roller 2 to rotate. When the roller 2 rotates in one direction, the flexible partition 3 is wound around it. At this time, the extended end of the flexible partition 3 is located in the second position, realizing full-cavity washing. When the roller 2 rotates in another direction, the flexible partition 3 is in a relaxed state. At this time, the flexible partition 3 moves forward to the first position under the action of the elastic component. That is, the elastic component makes the extended end of the flexible partition 3 maintain the tendency to move forward, thus realizing half-cavity washing.

[0038] In this embodiment, an elastic element is located below the flexible partition 3. The elastic element includes a first tension spring 51, a second tension spring 52, and a spring sheet 53. A fixing element 7 is fixedly installed in the housing 1 near the roller 2. One end of the first tension spring 51 is fixedly connected to the front end of the flexible partition 3, and the other end is fixedly connected to the first end of the spring sheet 53. One end of the second tension spring 52 is fixedly connected to the fixing element 7, and the other end is fixedly connected to the second end of the spring sheet 53. The first tension spring 51 is located in the first connecting rod 61, and the second tension spring 52 is located in the second connecting rod 62. The first connecting rod 61 and the second connecting rod 62 are rotatably connected by a vertically extending pivot 622. The spring sheet 53 is located at the connection between the first connecting rod 61 and the second connecting rod 62. The inner wall surface of the second connecting rod 62 adjacent to the first connecting rod 61 has an arc-shaped structure 621 that matches the spring sheet 53. The spring sheet 53 is partially attached to the arc-shaped structure 621. The first connecting rod 61 and the second connecting rod 62 serve as positioning and guiding elements.

[0039] In this embodiment, a fixing strip 31 is fixedly provided at the front end of the flexible partition 3, and the front end of the first tension spring 51 is connected to the fixing strip 31. The fixing member 7 is also in the shape of a strip extending left and right. The fixing member 7 is located in front of the roller 2 and below the flexible partition 3, so that the fixing member 7 will not interfere with the movement of the flexible partition 3.

[0040] In this embodiment, there are two sets of driving mechanisms, located on the left and right sides of the flexible partition 3 respectively, so that the flexible partition 3 is subjected to uniform force on the left and right sides and moves smoothly.

[0041] With the flexible partition 3 in the first position, the spring 53, the first tension spring 51, and the second tension spring 52 form a triangular shape that arches toward the side wall of the box 1 away from the corresponding side.

[0042] During the process of pulling the flexible partition 3 backward, the spring sheet 53 bends, causing the first tension spring 51 and the second tension spring 52 to change from a front-to-back extension state to a left-to-right extension state. The overall space occupied by the elastic element in the housing 1 is small, and the flexible partition 3 is wound around the roller 2 as much as possible. During the process of pulling the flexible partition 3 backward and bending the spring sheet 53, the spring sheet 53 drives the first tension spring 51 and the second tension spring 52 to move towards the inside of the housing 1. During this process, the first connecting rod 61 and the second connecting rod 62 gradually change from a triangular separation state to a closed state.

[0043] When the flexible partition 3 extends, the separation of the first tension spring 51 and the second tension spring 52 causes the fixing bar 31 to move forward. During this process, the spring piece 53 causes the first connecting rod 61 and the second connecting rod 62 to rotate and separate, as... Figure 4 As shown.

[0044] The drive unit 4 is located outside the housing 1. The output shaft of the drive unit 4 passes through the side wall of the housing 1 and is connected to the reel 2 for driving. In this way, the drive unit 4 does not occupy the internal space of the housing 1 and does not require waterproofing. The drive unit 4 can be a motor.

[0045] The left and right sides of the housing 1 are provided with slide rails 8 extending in the front-to-back direction. The left and right edges of the flexible partition 3 can be slidably placed in the corresponding slide rails 8, and the slide rails 8 guide the movement trajectory of the flexible partition 3. In this embodiment, the slide rails 8 are U-shaped, and the left and right edges of the flexible partition 3 are placed in the U-shaped grooves of the corresponding slide rails 8.

[0046] In order to improve the disinfection effect in the box 1, the fixing strip 31 is equipped with a disinfection component 9. During the movement of the flexible partition 3, the box 1 can be dynamically disinfected, reducing disinfection dead corners and achieving good disinfection effect. When the flexible partition 3 is positioned, localized sterilization can be enhanced in the box 1.

[0047] The disinfection component 9 is a UV lamp. The power cord connected to the UV lamp is partially threaded through the first link 61 and the second link 62, so that the power cord does not occupy additional space in the housing 1. After passing through the first link 61 and the second link 62, the power cord is connected to the circuit board. The UV lamp can use an existing structure.
