Description

Technical Field

[0001] The invention relates to a dishwasher. Background Art

[0002] At present, common dishwashers on the market generally include a housing and a spray device disposed in the housing. The spray device is used to draw water from the bottom of the housing into a water spray component and spray it into the washing chamber to wash the dishes. The washing chamber volume of most dishwashers is fixed and cannot be changed according to the number of dishes to be washed. When the number of dishes to be washed is small, placing the dishes in a larger washing chamber for washing not only affects the washing effect, but also causes a waste of water resources.

[0003] In addition, for some dishwashers with larger capacity, users are accustomed to placing the dishes in the dishwasher for storage after washing. In this case, if fewer dishes are used for each meal, the stored dishes will need to be washed together when washing the dishes next time, which will also cause a waste of water and electricity resources.

[0004] In response to the above problems, the Chinese utility model patent with patent number CN202023348649.2 (publication number CN215383808U) discloses "A dishwasher", which includes: a box body, having an inner cavity; a partition assembly, arranged in the inner cavity of the box body, for dividing the inner cavity of the box body into relatively independent upper and lower spaces; the partition assembly includes: a fixed plate, horizontally placed in the middle of the box body and connected to the inner wall of the box body; a movable plate, movably arranged on the fixed plate, for cooperating with the fixed plate to separate the upper space from the lower space or connect the upper space with the lower space; also includes: a surrounding plate, arranged on the lower wall surface of the fixed plate, and a relatively independent installation compartment is formed between the fixed plate and the inner wall of the box body; a driving member, arranged in the installation compartment, and the power output shaft passes through the surrounding plate and is 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 space from the lower space. The upper space can be used to store the washed dishes, and the lower space can be sprayed and cleaned separately. This is the "half-cavity washing" mode, which not only makes full use of the box 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 space with the lower space. This is the "full-cavity washing" mode, and the dishes in the upper space and the lower space are washed at the same time.

[0006] However, in the "full cavity wash" mode, the partition assembly has no function and also occupies the space inside the box; moreover, the current partition assembly has a single function and only has the function of dividing the interior of the box into an upper space and a lower space, without any other additional functions. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a dishwasher with a movable plate capable of driving a spraying part to move so as to reduce spraying blind angles in view of the current status of the prior art.

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

[0009] Box, open front;

[0010] The door body is movably arranged at the front opening of the box body to open or close the box body;

[0011] A partition assembly is arranged in the box body, and the partition assembly includes

[0012] A fixing plate is horizontally placed at the rear of the box body and connected to the inner wall of the box body, and when the door body is closed, there is a gap between the fixing plate and the door body;

[0013] The movable plate is arranged to be movable relative to the fixed plate in the front-rear direction, the movable plate can move forward to a first position to cover the gap and move backward to a second position to open the gap, when the movable plate is in the first position, the partition assembly can separate the box into relatively independent upper space and lower space, when the movable plate is in the second position, the upper space and the lower space are connected;

[0014] It is characterized by that it also includes

[0015] A spraying member, which is hollow inside and arranged on the movable plate, and is provided with a water inlet hole and a water spraying hole connected with the inside of the spraying member;

[0016] The water supply pipe is located at the rear side of the partition assembly, and the water supply pipe is connected with the water inlet hole of the spraying part through a bellows that can be extended and retracted forward and backward.

[0017] The spraying member can be arranged on the top wall of the movable plate. Preferably, the spraying member is arranged on the bottom wall of the movable plate, and the water spraying hole faces downward. When the movable plate is in the second position, the movable plate is located below the fixed plate. In this way, when washing in the half cavity, the spraying member also participates in the cleaning of the lower space, thereby improving the cleaning effect of the dishes in the lower space.

[0018] Due to the gravity of water, the bellows will sag after stretching, especially in the middle part of the bellows, which will affect the subsequent contraction of the bellows. The sagging of the bellows will also cause the water flow to fluctuate and oscillate. Therefore, the dishwasher also includes a lifting mechanism provided between the fixed plate and the bellows for lifting the bellows upward. The lifting mechanism is detachably connected to the bellows, so that the bellows remains basically horizontal and does not sag in the stretched state. When the bellows needs to contract, the lifting mechanism releases the bellows so that the bellows can contract normally.

[0019] The lifting mechanism can have various structural forms. Preferably, the lifting mechanism includes a first magnetic part arranged on the bellows and a second magnetic part arranged on the fixed plate. The first magnetic part and the second magnetic part can be magnetically attracted to each other. The cooperation between the second magnetic part and the second magnetic part makes it easy to disassemble and assemble the lifting mechanism and the bellows.

[0020] Preferably, the second magnetic member can move upward to the first position or downward to the second position. When the second magnetic member is in the first position, there is no magnetic attraction between the first magnetic member and the second magnetic member. When the second magnetic member is in the second position, the first magnetic member and the second magnetic member are magnetically attracted together.

[0021] In order to enable the second magnetic part to move upward to the first position or downward to the second position, the dishwasher also includes a controller, and the fixed plate is also provided with an electromagnet and a sensor that can sense the magnetism of the first magnetic part. The electromagnet includes the second magnetic part, and the sensor is electrically connected to the input end of the controller. When the first magnetic part is close to the sensor, the sensor sends a signal to the controller, and the controller controls the second magnetic part of the electromagnet to move downward, and at this time the second magnetic part is magnetic and is magnetically attracted to the first magnetic part. When the first magnetic part is far away from the sensor, the controller controls the second magnetic part of the electromagnet to move upward and separate from the first magnetic part, and at this time the magnetism of the second magnetic part disappears.

[0022] The sensor may be in various forms, and preferably, the sensor includes a reed switch. When the first magnetic member is close to the reed switch, the reed switch is turned on and sends a signal to the controller; when the first magnetic member is away from the reed switch, the reed switch is turned off and does not send a signal to the controller.

[0023] In order to increase the spraying range of the spray piece, a water pipe is installed on the movable plate, the corrugated pipe and the spray piece are connected through the water pipe, and the spray piece can rotate around the vertically extending axis, so that the spray piece can not only move back and forth with the movable plate, but also rotate, with multiple active dimensions, and the spraying range of the water sprayed from the water spray hole is large.

[0024] In order to increase the spraying range of the spraying parts, there are at least two spraying parts, and correspondingly, there are at least two bellows, and the water supply pipe includes a pipe body and a water distribution pipe connected to the pipe body, and the water distribution pipe has a water distribution port connected to the bellows in a one-to-one correspondence. In this way, there are multiple spraying parts to spray water, and the spraying range is large.

[0025] Compared with the prior art, the advantages of the present invention are as follows: First, by arranging the spraying parts on the movable plate, the spraying parts on the movable plate can be controlled to move forward and backward to focus on cleaning the dishes at different positions during full-cavity washing, thereby achieving fixed-point spraying, so that the partition also plays a role during full-cavity washing;

[0026] Second, because the spray parts are movable, smaller spray parts can be used to achieve a larger spray area. The advantages are: ① Small spray parts take up less space in the box; ② The motor power required to drive the small spray parts is low, which saves energy; ③ Small spray parts divert less water, so the total amount of water required for cleaning is low, which saves water.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 4 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, a partition assembly 2, a spray element 3, a water supply pipe 4 and a lifting mechanism.

[0033] The box body 1 is open at the front, and the door body is movably arranged at the front opening of the box body 1 to open or close the box body 1. The partition assembly 2 is arranged in the box body 1, and the partition assembly 2 includes a fixed plate 21 and a movable plate 22. The fixed plate 21 is horizontally arranged at the rear of the box body 1 and connected to the inner wall of the box body 1. When the door body is closed, there is a gap between the fixed plate 21 and the door body.

[0034] The movable plate 22 is arranged to be movable relative to the fixed plate 21 in the front-to-rear direction. The movable plate 22 can move forward to a first position to cover the gap and move backward to a second position to open the gap. When the movable plate 22 is in the first position, the partition assembly 2 can separate the box body 1 into relatively independent upper space 11 and lower space 12. When the movable plate 22 is in the second position, the upper space 11 and the lower space 12 are connected, and the movable plate 22 is located below the fixed plate 21.

[0035] A motor is provided at the rear of the box body 1, and the motor is drivingly connected to a screw rod 24 extending in the front-rear direction. A nut 25 cooperating with the screw rod 24 is provided on the moving plate 22, so that the moving plate 22 can move forward and backward.

[0036] In addition, a guide rod 26 extending in the front-rear direction is provided on the fixed plate 21 , and a guide sleeve 27 for the guide rod 26 to pass through is provided on the movable plate 22 . The guide sleeve 27 can slide along the guide rod 26 to guide the moving trajectory of the movable plate 22 .

[0037] The above are all prior art and will not be described in detail here.

[0038] A water supply pipe 4 is provided in the box body 1, and the water supply pipe 4 is located on the rear side of the partition assembly 2. The interior of the spray component 3 is hollow and is provided on the movable plate 22. The spray component 3 is provided with a water inlet hole 31 and a water spray hole 32 connected to the interior thereof. The water supply pipe 4 is connected to the water inlet hole 31 of the spray component 3 through a bellows 5 which can be extended and retracted forward and backward.

[0039] The spray member 3 is arranged on the bottom wall of the movable plate 22, and the water spray hole 32 faces downward. During half-cavity washing, the spray member 3 also participates in the cleaning of the lower space 12, thereby improving the cleaning effect of the tableware in the lower space 12. In addition, the movable plate 22 moves back and forth to allow the spray member 3 thereon to focus on cleaning the tableware at different positions, thereby realizing fixed-point spraying.

[0040] In order to increase the spraying range of the spraying member 3, a water pipe 6 is installed on the movable plate 22, and the bellows 5 and the spraying member 3 are connected through the water pipe 6, and the spraying member 3 can rotate around the vertically extending axis, so that the spraying member 3 can not only move forward and backward with the movable plate 22, but also rotate, with multiple active dimensions, and the spraying range of the water sprayed from the water spray hole 32 is large. The spraying member 3 can rotate under the action of hydraulic force, and the existing way of rotating the spray arm of the dishwasher can be adopted. The existing buckle can be set on the bottom wall of the movable plate 22 to position the water pipe 6.

[0041] In order to increase the spraying range of the spraying parts 3, there are at least two spraying parts 3, and correspondingly, there are at least two bellows 5. The water supply pipe 4 includes a pipe body 41 and a water distribution pipe 42 connected to the pipe body 41. The water distribution pipe 42 has a water distribution port that is connected to the bellows 5 in a one-to-one correspondence. In this way, there are multiple spraying parts 3 to spray water, and the spraying range is large.

[0042] Due to the gravity of water, the bellows 5 will sag after being stretched, especially in the middle part of the bellows 5. This will affect the subsequent contraction of the bellows 5, and the sagging of the bellows 5 will also cause the water flow to fluctuate and oscillate. Therefore, the dishwasher also includes a lifting mechanism provided between the fixed plate 21 and the bellows 5 for lifting the bellows 5 upward, so that when the bellows 5 is in the stretched state, the lifting mechanism is detachably connected to the bellows 5 to maintain a basically horizontal state without sagging, and when the bellows 5 needs to contract, the lifting mechanism releases the bellows 5, so that the bellows 5 can contract normally.

[0043] The lifting mechanism can be an existing electric manipulator structure that can grasp or release the bellows 5. In this embodiment, the lifting mechanism includes a first magnetic component provided on the bellows 5 and a second magnetic component 7 provided on the fixed plate 21. The second magnetic component 7 can move upward to the first position or downward to the second position. When the second magnetic component 7 is in the first position, there is no magnetic attraction between the first magnetic component and the second magnetic component 7. When the second magnetic component 7 is in the second position, the first magnetic component and the second magnetic component 7 are magnetically attracted together.

[0044] Iron powder can be added to a local position when the bellows 5 is blow-molded, or the magnet can be injection-molded at a local position of the bellows 5 .

[0045] In order to enable the second magnetic part 7 to move upward to the first position or downward to the second position, the dishwasher also includes a controller, and an electromagnet and a sensor that can sense the magnetism of the first magnetic part are also provided on the fixed plate 21. The electromagnet includes the second magnetic part 7, and the sensor is electrically connected to the input end of the controller. When the first magnetic part is close to the sensor, the sensor senses the magnetism of the first magnetic part and sends a signal to the controller. The controller controls the second magnetic part 7 of the electromagnet to move downward, and at this time the second magnetic part 7 has magnetism and is attracted to the first magnetic part. When the first magnetic part is far away from the sensor, the sensor cannot sense the magnetism of the first magnetic part and sends a signal to the controller. The controller controls the second magnetic part 7 of the electromagnet to move upward and separate from the first magnetic part, and at this time the magnetism of the second magnetic part 7 disappears.

[0046] In this embodiment, the sensor includes a reed switch. When the first magnetic member is close to the reed switch, the reed switch is turned on and sends a signal to the controller; when the first magnetic member is away from the reed switch, the reed switch is turned off and sends a signal to the controller.

[0047] The specific working process of the lifting mechanism is as follows:

[0048] The movable plate 22 extends forward, and the first magnetic part on the bellows 5 moves just below the reed switch. The signal is triggered and sent to the controller. The controller controls the telescopic electromagnet at the reed switch, which is originally in a retracted state, to extend the second magnetic part 7 and make the second magnetic part 7 magnetic to attract the bellows 5 below it.

[0049] The moving plate 22 retracts backwards, and the first magnetic member on the bellows 5 moves away from the bottom of the reed switch. The signal is triggered, and a signal is sent to the controller. The controller controls the second magnetic member 7 of the electromagnet at the reed switch to change from being magnetic to being non-magnetic and retract quickly. In this way, the bellows 5 can be compressed smoothly, and the moving plate 22 will not interfere with or collide with the second magnetic member 7.

[0050] Each time the reed switch signal is triggered, the action of the electromagnet is based on its last action. For example, the last time the signal is triggered, the second magnetic member 7 is extended and has magnetism, then the next time the signal is triggered, the action is that it has no magnetism and retracts. In this way, the moving plate 22 moves back and forth to control whether the electromagnet absorbs or "releases" the bellows 5.

[0051] The electromagnet can only be in two states: 1. The second magnetic part 7 is retracted and the second magnetic part 7 is not magnetic; 2. The second magnetic part 7 is extended and the second magnetic part 7 is magnetic. The advantage of designing the second magnetic part 7 to be telescopic is that the space gap between the fixed plate 21 and the movable plate 22 is fully utilized, so that the volume of the partition does not need to be increased, especially the longitudinal dimension (thickness direction). When the electromagnet is energized, the second magnetic part 7 is magnetic, and when the electromagnet is not energized, the second magnetic part 7 is not magnetic. This is the prior art.

[0052] The electromagnet adopts the existing structure, and the electrical connection between the reed switch sensor and the controller, and between the controller and the electromagnet can all adopt the existing technology.

[0053] As can be seen from the above, during the forward and backward movement of the moving plate 22, a signal can be continuously triggered to control the second magnetic part 7 of the electromagnet to extend and retract upward and downward and whether it is turned on (having magnetism after being turned on), that is, to achieve the purpose of sucking or "loosening" the bellows 5, so that the bellows 5 can always remain horizontal and not sag, so that the compression of the bellows 5 is not affected, and the fluctuation and oscillation of the water flow can also be reduced.

[0054] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying 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. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
