Description

Technical Field

[0001] This invention 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 mechanism 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. The upper space can be used to store the washed dishes, while the lower space can be sprayed and washed separately. This not only makes full use of the cabinet space but also helps to 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 to connect the upper and lower spaces, and the dishes in the upper and lower spaces are washed at the same time.

[0006] For side-opening dishwashers, the dish racks are pulled forward outside the cabinet to facilitate loading and unloading. The dish racks typically have a perforated structure made of several frame strips to allow water to drain. When soiled dishes are placed on the racks, grease and debris may leak out. With the door open, the racks are directly above the door, and grease and debris dripping from the racks will fall onto the door. When the door is closed, if the dishwasher is in a half-cavity wash mode, the upper space is easily contaminated by grease from the door. Furthermore, the door usually has an exhaust vent; grease dripping into the vent may cause blockages, affecting the dishwasher's ventilation performance. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a dishwasher that prevents oil and other contaminants from dripping from the dish rack and contaminating the door, in light of the current state of the technology.

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

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

[0010] The dish rack can move back and forth in and out of the box;

[0011] The door is rotatably positioned at the front opening of the enclosure, allowing the enclosure to be opened or closed.

[0012] Its characteristic is that it also includes

[0013] A baffle that can move back and forth to enter and exit the cabinet. When the door is open, the baffle is horizontally positioned between the dish rack and the door.

[0014] A first drive mechanism is located beside the movement path of the bowl rack. The first drive mechanism includes...

[0015] Mounting block, for fixed installation on the dish rack;

[0016] The first drive unit has a first output shaft extending in a left-right direction, the first output shaft being rotatable about its axis;

[0017] The first link has its first end connected to the first output shaft and fixed circumferentially relative to the first output shaft;

[0018] The first end of the second link is rotatably connected to the second end of the first link, and the rotation axes of the two extend in the left and right directions.

[0019] The third link has its first end detachably connected to the baffle, and its position near the second end is rotatably connected to the second end of the second link, with their rotation axes extending in the left-right direction. The second end of the third link is connected to the mounting block, and the two are relatively fixed in the front-back direction.

[0020] In order to adapt to different user needs, a fixing plate is horizontally placed at the rear of the box, and there is a gap between the fixing plate and the door when the door is closed;

[0021] When the third link is detached from the baffle, the baffle can move in the front-back direction within the housing to either the first or second position. When the baffle is in the first position, it is located at the notch and cooperates with the fixed plate to divide the interior of the housing into an independent upper space and a lower space. When the baffle is in the second position, it is offset from the notch, thereby connecting the upper space and the lower space.

[0022] When the number of dishes to be washed is small, the baffle moves to separate the upper and lower spaces. The upper space can be used to store the washed dishes, while the lower space can be sprayed and washed 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 baffle moves to connect the upper and lower spaces, washing the dishes in both spaces at the same time. At this time, the baffle is detached from the third link and can move independently.

[0023] The baffle can be manually pushed and pulled back and forth, but this is laborious and inconvenient. Therefore, the dishwasher also includes a second drive mechanism. When the third link is detached from the baffle, the baffle moves to the first position or the second position under the drive of the second drive mechanism.

[0024] The second drive mechanism can have various structural forms, such as an electric actuator, or it can include...

[0025] The second driving component is fixed relative to the housing;

[0026] The screw is fixedly installed in the housing and extends in the front-to-back direction, and is connected to the second driving component for driving.

[0027] A nut sleeve is fixedly mounted on the baffle, and the nut sleeve is threadedly connected to the screw. When the second driving component operates, the screw rotates, and the nut sleeve moves along the screw, thereby driving the baffle to move back and forth.

[0028] In order for the baffle to be connected to or detached from the third link, the third link is fixed relative to the mounting block in the front-to-back direction. The baffle and the third link are detachably connected by a pin hole and a pin shaft. The pin shaft extends in the left-to-right direction, and the third link can move left and right relative to the mounting block to a third position and a fourth position. When the third link is in the third position, the pin shaft passes through the pin hole. When the third link is in the fourth position, the pin shaft disengages from the pin hole.

[0029] In order to enable the third link to move left and right, the dishwasher also includes a drive assembly for driving the third link to move left and right, and the drive assembly is connected to the third link.

[0030] The drive assembly can drive only the third link, causing the third link to move left and right. However, since the third link is directly or indirectly connected to the second and first links, both the first and second links can move in the left and right directions. The drive assembly is connected to the first link, so that driving the first link to move left and right causes the second and third links to move left and right synchronously, preventing interference between components.

[0031] Preferably, the housing is equipped with a water supply pipe, the baffle has a water flow channel, and the baffle also has multiple water outlets connected to the water flow channel. The water supply pipe and the water flow channel are connected by a retractable flexible hose. The water spraying during the movement of the baffle ensures a wide water coverage area and reduces cleaning dead zones; at least two of the water outlets have different orientations, for example, some outlets are angled upwards to clean the tableware in the upper space, and some outlets are angled downwards to clean the tableware in the lower space.

[0032] Preferably, a turbidity sensor is provided at the front of the baffle, so that the cleaning sequence can be intelligently selected according to the turbidity of the cleaning water.

[0033] In order to guide the movement trajectory of the baffle and the dish rack, the dishwasher also includes a first guide structure for guiding the dish rack in the front-back direction and a second guide structure for guiding the baffle in the front-back direction.

[0034] Compared with the prior art, the advantages of the present invention are as follows: By setting a baffle, when the dish rack is pulled forward, the baffle is located between the dish rack and the door. In this way, the oil and other kitchen waste dripping from the dishes placed in the dish rack can be caught by the baffle, and the kitchen waste will not drip onto the door and block the vent on the door. In addition, when the dish rack is pushed back into the box, the baffle is also pushed back into the box, which will not affect the closing of the door. Moreover, the oil on the baffle can be sprayed away by the spray arm in the box. Furthermore, the third link and the baffle can be detachably connected, and the baffle can move synchronously with the dish rack. The baffle can also be independent of the first drive mechanism. For example, after the dishes are washed, it is only necessary to take the dishes out of the dish rack for the user to use. At this time, the washed dishes will not drip oil, so there is no need to move the baffle out, reducing the power of the first drive mechanism. Attached Figure Description

[0039] Figure 5 for Figure 4 A magnified view of a portion of the image;

[0040] Figure 6 This is a structural schematic diagram of an embodiment of the present invention (the baffle is located outside the box). Detailed Implementation

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] like Figures 1-6 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a dish rack 2, a baffle 3, and a fixing plate (not shown in the figure).

[0043] The front of the box 1 is open, and the front of the box 1 is provided with a rotatable door 11. The rotation axis of the door 11 extends in the left and right direction. The door 11 can open or close the front opening of the box 1. The inner wall of the door 11 is provided with an exhaust port that can communicate with the outside.

[0044] The dish rack 2 can move back and forth in and out of the cabinet 1. In this embodiment, the dish rack 2 is located at the upper part of the cabinet 1, and a dish basket can also be installed at the lower part of the cabinet 1. The dish rack 2 is generally a hollow structure formed by several frame strips to allow water to drain. When contaminated tableware is placed on the dish rack 2, oil stains and debris on the tableware may leak out from the dish rack 2. When the door is open, the dish rack 2 is located directly above the door 11. Oil stains and debris dripping from the dish rack 2 will drip onto the door 11. The door 11 is generally equipped with an exhaust vent. If oil stains drip into the exhaust vent, it may cause blockage and affect the exhaust performance of the dishwasher.

[0045] The above are existing technologies, and will not be elaborated further here.

[0046] To address the issue of oil stains dripping from the dish rack 2 contaminating the door 11, this embodiment includes a baffle 3. The baffle 3 can move back and forth to enter and exit the cabinet 1. When the door 11 is open, the baffle 3 is positioned horizontally between the dish rack 2 and the door 11, so that oil stains dripping from the dish rack 2 will fall onto the baffle 3 instead of dripping directly onto the door 11.

[0047] In this embodiment, the baffle 3 not only serves to collect oil stains on the dish rack 2, but also cooperates with the fixing plate to form a partition assembly. A fixing plate is horizontally placed at the rear of the housing 1. When the door 11 is closed, there is a notch between the fixing plate and the door 11. The baffle 3 can move in the front-back direction within the housing 1 to either a first position or a second position. When the baffle 3 is in the first position, it is positioned at the notch and cooperates with the fixing plate to divide the interior of the housing 1 into two independent spaces: an upper space 12 and a lower space 13. When the baffle 3 is in the second position, it is offset from the notch, thus connecting the upper space 12 and the lower space 13. The cooperation between the baffle 3 and the fixing plate can be found in the patents disclosed in the background art, and will not be repeated here.

[0048] When the number of tableware to be washed is small, the baffle 3 moves to separate the upper space 12 from the lower space 13. The upper space 12 can be used to store the washed tableware, while the lower space 13 can be sprayed and washed separately. This not only makes full use of the space of the cabinet 1, but also helps to save water and electricity. When the number of tableware to be washed is large, the baffle 3 moves to connect the upper space 12 with the lower space 13, and washes the tableware in both the upper space 12 and the lower space 13 at the same time.

[0049] In other words, the baffle 3 in this embodiment can be in three positions. When the door 11 is open and the dish rack 2 is pulled out of the cabinet 1, the baffle 3 is located outside the cabinet 1 and between the dish rack 2 and the door 11, and can catch the oil droplets dripping from the dish rack 2. When the door 11 is closed and the dish rack 2 is inside the cabinet 1, the baffle 3 can move to the first position or the second position inside the cabinet 1 to achieve full cavity washing and half cavity washing.

[0050] In order to achieve the above-mentioned movement state of the baffle 3 and the dish rack 2, the dishwasher of this embodiment is provided with a first drive mechanism 4, a second drive mechanism (not shown in the figure) and a drive assembly (not shown in the figure). The dishwasher also includes a first guide structure 5 for guiding the dish rack 2 in the front-back direction and a second guide structure 6 for guiding the baffle 3 in the front-back direction, so that the dish rack 2 and the baffle 3 can only move in the front-back direction.

[0051] The first guide structure 5 includes a guide rail 51 and a sliding member 52. The left and right sides of the bowl rack 2 are provided with guide rails 51 extending in the front-back direction. The guide rails 51 can move back and forth to enter and exit the box 1. The guide rails 51 have guide grooves 53 extending in the front-back direction. The box 1 is provided with guide parts 14 that cooperate with the guide grooves 53. Both ends of the guide rails 51 are provided with limiting parts 54.

[0052] The bowl rack 2 is provided with a slider 52, which can slide and cooperate with the guide rail 51. When the slider 52 abuts against the limiting part 54, the bowl rack 2 and the guide rail 51 are relatively fixed in the front-back direction. The slider 52 is a wheel that can rotate around an axis extending in the left-right direction. In this way, the slider 52 and the guide rail 51 have rolling friction, and the friction force is small.

[0053] When the slider 52 is not abutting against the limiting part 54, the slider 52 slides along the guide rail 51. At this time, the guide rail 51 remains stationary, and only the bowl rack 2 moves. When the slider 52 abuts against the limiting part 54, the slider 52 and the guide rail 51 are relatively fixed in the forward or backward movement direction. At this time, the guide rail 51 and the bowl rack 2 move synchronously, and the bowl rack 2 is relatively fixed relative to the guide rail 51 in the forward and backward direction. This cooperation between the guide rail 51 and the bowl rack 2 allows the bowl rack 2 to have a longer movement trajectory.

[0054] like Figure 3 As shown, the second guide structure 6 includes a guide rod 61 extending in the front-rear direction and a guide sleeve 62 through which the guide rod 61 passes. The guide rod 61 is connected to the baffle 3, and the guide sleeve 62 is fixedly installed in the housing 1. Alternatively, the guide rod 61 can be fixedly installed in the housing 1, and the guide sleeve 62 can be connected to the baffle 3.

[0055] The first guide structure 5 and the second guide structure 6 mentioned above are both existing technologies.

[0056] The baffle 3 and the bowl rack 2 can move under the action of the first drive mechanism 4. The first drive mechanism 4 is located on the side of the movement path of the bowl rack 2. The first drive mechanism 4 includes a mounting block 41, a first drive member 42, a first connecting rod 43, a second connecting rod 44 and a third connecting rod 45.

[0057] like Figures 2-5As shown, mounting block 41 is fixedly mounted on bowl rack 2. First drive member 42 has a first output shaft extending in the left-right direction. The first output shaft can rotate around its axis. The first end of first link 43 is connected to the first output shaft and is fixed circumferentially relative to the first output shaft. The first end of second link 44 is rotatably connected to the second end of first link 43, and their rotation axes extend in the left-right direction. The first end of third link 45 is detachably connected to baffle 3. The position of the second end of third link 45 adjacent to the second end of second link 44 is rotatably connected to the second end of second link 44. The rotation axes of second link 44 and third link 45 extend in the left-right direction. The second end of third link 45 is connected to mounting block 41, and the two are fixed relative to each other in the front-back direction.

[0058] The mounting block 41 is provided with a mounting groove 411 and a pin 412 extending in the left and right direction. The pin 412 passes through the third link 45, so that the third link 45 is fixed relative to the mounting block 41 in the front and back direction. The second end of the third link 45 is inserted into the mounting groove 411.

[0059] The first driving component 42 can be a motor. When the motor is working, it drives the first connecting rod 43 to rotate, and the second connecting rod 44 rotates accordingly. Because the bowl rack 2 and the baffle 3 are constrained by the first guide structure 5 and the second guide structure 6 respectively, the bowl rack 2 and the baffle 3 can move back and forth under the action of the third connecting rod 45.

[0060] Because the first end of the third link 45 is detachably connected to the baffle 3, when the two are detached, the first drive mechanism 4 can only drive the bowl rack 2 to move, but cannot drive the baffle 3. At this time, the baffle 3 can move to the first position and the second position under the action of the second drive mechanism.

[0061] The second drive mechanism includes a second drive component, a screw, and a nut sleeve. The second drive component is fixed relative to the housing 1. The screw is fixed in the housing 1 and extends in the front-to-back direction. The screw is driven by the second drive component. The second drive component can be a motor.

[0062] The nut sleeve is fixedly installed on the baffle 3, and the nut sleeve is threadedly connected to the screw. When the second driving component operates, the screw rotates, and the nut sleeve moves along the screw, thereby driving the baffle 3 to move back and forth. The second driving mechanism adopts existing technology, and reference can be made to the patents disclosed in the background art.

[0063] In order for the baffle 3 to be connected to or detached from the third link 45, the third link 45 is fixed relative to the mounting block 41 in the front-rear direction. The baffle 3 and the third link 45 are detachably connected through the pin hole 451 and the pin 31. The pin 31 extends in the left-right direction, and the third link 45 can move left and right relative to the mounting block 41 to the third position and the fourth position. When the third link 45 is in the third position, the pin 31 passes through the pin hole 451. When the third link 45 is in the fourth position, the pin 31 disengages from the pin hole 451.

[0064] In this embodiment, the pin 31 is disposed on the baffle 3, and the pin hole 451 is disposed on the third connecting rod 45. Alternatively, the pin 31 can be disposed on the third connecting rod 45, and the pin hole 451 can be disposed on the baffle 3.

[0065] In this embodiment, the first link 43 is driven to move in the left-right direction by the drive assembly. That is, the first link 43 can move left and right relative to the first output shaft, but the first link 43 and the first output shaft are relatively fixed in the circumferential direction. The left-right movement of the first link 43 will drive the second link 44 and the third link 45 to move left and right synchronously, realizing the drive assembly and the third link 45 to be driven and connected. The drive assembly can be an electric push rod, which moves in the left-right direction, or it can be an electromagnet.

[0066] In other words, both the first link 43 and the second link 44 can move in the left and right directions. The drive assembly is connected to the first link 43, thus driving the first link 43 to move left and right, so that the second link 44 and the third link 45 move left and right synchronously.

[0067] The working process of the dishwasher in this embodiment is as follows:

[0068] When it is necessary to pull the bowl rack 2 and the baffle 3 out of the housing 1, the third connecting rod 45 is connected to the baffle 3, and the first driving component 42 is activated, pulling the bowl rack 2 and the baffle 3 forward synchronously. After the tableware on the bowl rack 2 is placed, the first driving component 42 is activated, pulling the bowl rack 2 and the baffle 3 backward synchronously. In this step, if it is not necessary for the baffle 3 to catch the oil droplets falling from the bowl rack 2, the third connecting rod 45 and the baffle 3 can be detached, and the first driving mechanism can only drive the bowl rack 2.

[0069] Then the drive assembly drives the third link 45 and the baffle 3 to disengage, and the second drive mechanism drives the baffle 3 to move to the first position or the second position as needed, so as to perform full cavity washing or half cavity washing.

[0070] When it is necessary to connect the third link 45 and the baffle 3, the baffle is moved to the position corresponding to the pin 31 and the pin hole 451. Then the drive assembly drives the first link 43 to move in the left and right directions, and the third link 45 moves in the left and right directions simultaneously, so that the pin 31 passes through the pin hole 451.

[0071] A water supply pipe 7 is provided at the rear of the housing 1. The water supply pipe 7 can supply water to the spray arm in the housing 1, which is the prior art. In this embodiment, the water supply pipe 7 can also supply water to the baffle 3, as follows:

[0072] The baffle 3 is equipped with a water flow channel and multiple water outlets 32 connected to the water flow channel. The water supply pipe 7 and the water flow channel are connected by a retractable flexible hose 71 (such as a corrugated pipe). The water spraying during the movement of the baffle 3 results in a wide water coverage area and fewer cleaning dead zones. At least two of the water outlets 32 have different orientations; for example, some water outlets 32 are angled upwards to clean the tableware in the upper space 12, while others are angled downwards to clean the tableware in the lower space 13.

[0073] The front of the baffle 3 can be equipped with a turbidity sensor, so that the washing sequence can be intelligently selected according to the turbidity of the washing water. For how to select the washing sequence according to the turbidity, you can refer to existing intelligent washing methods, such as the Chinese invention patent application "A washing method and dishwasher" published by CN201810529986.X (announcement number CN110537884B).

[0074] Preferably, the turbidity sensor is placed in front of the baffle 3. Within the moving range of the baffle 3, the turbidity value of the water can be detected over a wider range, and the turbidity value can be captured in segments. Spatially, a turbidity value X is obtained every L distance, and A / L turbidity values ​​Xi can be captured within the moving range A. Temporally, a turbidity value Y can be obtained every m time interval, and M / m turbidity values ​​Yj can be detected within the detection time M. In this way, the turbidity value is measured in two dimensions, in time and space, and the turbidity signal is more accurate and real.

[0075] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
