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 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. The upper space can be used to store the washed dishes, while the lower space can be sprayed and washed separately. This is the "half-cavity washing" mode, which 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. This is the "full-cavity washing" mode, which washes the dishes in both the upper and lower spaces simultaneously.

[0006] However, in the "full cavity washing" mode, the partition assembly is ineffective and occupies space inside the cabinet; moreover, the current partition assembly has a single function, only dividing the interior of the cabinet into upper and lower spaces, 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 in which the movable plate can drive the spray components to move to reduce the spray dead angle, in view of the current situation of the prior art.

[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 door is movably located at the front opening of the box to allow the box to be opened or closed.

[0011] A partition assembly is disposed within the housing, the partition assembly comprising:

[0012] A fixing plate is placed horizontally at the rear of the box and connected to the inner side wall of the box. When the door is closed, there is a notch between the fixing plate and the door.

[0013] A movable plate is arranged to move relative to the fixed plate in a front-back direction. The movable plate can move forward to a first position to cover the gap and backward to a second position to open the gap. When the movable plate is in the first position, the partition assembly can divide the box into relatively independent upper and lower spaces. When the movable plate is in the second position, the upper and lower spaces are connected.

[0014] Its characteristic is that it also includes

[0015] A spraying component, hollow inside and mounted on a movable plate, is provided with a water inlet and a spraying hole that communicate with its interior.

[0016] A water supply pipe is located on the rear side of the partition assembly, and the water supply pipe is connected to the water inlet of the spray element through a corrugated pipe that can extend and retract.

[0017] The spray nozzle can be installed on the top wall of the movable plate. Preferably, the spray nozzle is installed on the bottom wall of the movable plate with the spray holes facing downwards. When the movable plate is in the second position, it is located below the fixed plate. In this way, during the half-cavity washing process, the spray nozzle also participates in the cleaning of the lower space, improving the cleaning effect of the tableware in the lower space.

[0018] Due to the force of gravity, the corrugated pipe will sag after elongation, especially in the middle of the pipe. This will affect the subsequent contraction of the pipe and cause fluctuations and oscillations in the water flow. Therefore, the dishwasher also includes a lifting mechanism located between the fixed plate and the corrugated pipe to lift the pipe upward. The lifting mechanism is detachably connected to the corrugated pipe so that the pipe remains basically horizontal and does not sag when elongated. When the pipe needs to contract, the lifting mechanism releases the pipe, allowing it to contract normally.

[0019] The lifting mechanism can have various structural forms. Preferably, the lifting mechanism includes a first magnetic component disposed on the corrugated pipe and a second magnetic component disposed on the fixed plate. The first magnetic component and the second magnetic component can be magnetically attracted to each other. The cooperation between the second magnetic component and the second magnetic component makes it convenient to assemble and disassemble the lifting mechanism from the corrugated pipe.

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

[0021] To enable the second magnetic component to move upward to the first position or downward to the second position, the dishwasher also includes a controller. The fixed plate is also equipped with an electromagnet and a sensor that can sense the magnetism of the first magnetic component. The electromagnet includes the second magnetic component. The sensor is electrically connected to the input terminal of the controller. When the first magnetic component is close to the sensor, the sensor sends a signal to the controller, and the controller controls the second magnetic component of the electromagnet to move downward. At this time, the second magnetic component has magnetism and is attracted to the magnetism of the first magnetic component. When the first magnetic component is away from the sensor, the controller controls the second magnetic component of the electromagnet to move upward and disengage from the first magnetic component. At this time, the magnetism of the second magnetic component disappears.

[0022] The sensor can take many forms; preferably, it includes a reed switch. When the first magnetic element approaches the reed switch, the reed switch is turned on, sending a signal to the controller; when the first magnetic element moves away from the reed switch, the reed switch is turned off, and no signal is sent to the controller.

[0023] To increase the spraying range of the spraying component, a water pipe is installed on the moving plate. The corrugated pipe and the spraying component are connected through the water pipe, and the spraying component can rotate around a vertically extending axis. In this way, the spraying component can not only move back and forth with the moving plate, but also rotate, with multiple dimensions of movement, and the spraying range of the water sprayed from the water nozzle is large.

[0024] To increase the spray range of the spray elements, there are at least two spray elements, and correspondingly, at least two corrugated pipes. The water supply pipe includes a pipe body and a branch pipe connected to the pipe body, and the branch pipe has a branch outlet that corresponds to and communicates with the corrugated pipe. In this way, multiple spray elements spray water, resulting in a large spray range.

[0025] Compared with the prior art, the advantages of the present invention are as follows: First, by setting spray elements on the moving plate, the present invention can control the moving plate to move back and forth during full cavity washing so that the spray elements on it can focus on cleaning the tableware in different positions, thus achieving point spraying. In this way, the partition also plays a role during full cavity washing.

[0026] Secondly, because the spray components are movable, a larger spray area can be achieved with smaller spray components. The advantages are: ① Smaller spray components occupy less space in the cabinet; ② The motor power required to drive the smaller spray components is low, saving energy; ③ The smaller spray components divert less water, resulting in a lower total water volume required for cleaning, saving water.

[0030] Figure 4 for Figure 3 A partial structural diagram. Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

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

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

[0034] The movable plate 22 is arranged to move relative to the fixed plate 21 in the front-back 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 divide the box 1 into a relatively independent upper space 11 and a lower space 12. When the movable plate 22 is in the second position, the upper space 11 and the lower space 12 are connected. The movable plate 22 is located below the fixed plate 21.

[0035] A motor is provided at the rear of the housing 1. The motor is connected to a lead screw 24 extending in the front-to-back direction. A nut 25 that cooperates with the lead screw 24 is provided on the movable plate 22, so that the movable plate 22 can move back and forth.

[0036] In addition, the fixed plate 21 is provided with a guide rod 26 extending in the front-back direction, and the movable plate 22 is provided with a guide sleeve 27 through which the guide rod 26 passes. The guide sleeve 27 can slide along the guide rod 26 to guide the movement trajectory of the movable plate 22.

[0037] The above are all existing technologies and will not be elaborated further here.

[0038] The housing 1 is equipped with a water supply pipe 4, which is located on the rear side of the partition assembly 2. The spray component 3 is hollow inside and is mounted on the movable plate 22. The spray component 3 is equipped with a water inlet 31 and a spray hole 32 that are connected to its interior. The water supply pipe 4 is connected to the water inlet 31 of the spray component 3 through a corrugated pipe 5 that can extend and retract back and forth.

[0039] The spray element 3 is located on the bottom wall of the movable plate 22, with the spray holes 32 facing downwards. During the half-cavity washing, the spray element 3 also participates in the cleaning of the lower space 12, improving the cleaning effect of the tableware in the lower space 12. Furthermore, the movable plate 22 moves back and forth, allowing the spray element 3 on it to focus on cleaning tableware in different positions, thus achieving point-to-point spraying.

[0040] To increase the spray range of the spray element 3, a water pipe 6 is installed on the movable plate 22. The corrugated pipe 5 and the spray element 3 are connected through the water pipe 6, and the spray element 3 can rotate around a vertically extending axis. This allows the spray element 3 to not only move back and forth with the movable plate 22 but also rotate, providing multiple dimensions of movement and a large spray range from the spray nozzles 32. The spray element 3 can rotate under hydraulic pressure, similar to the rotation of the spray arms in existing dishwashers. Existing clips can be installed on the bottom wall of the movable plate 22 to position the water pipe 6.

[0041] To increase the spray range of the spray element 3, there are at least two spray elements 3, and correspondingly, there are at least two corrugated pipes 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 water distribution ports that are connected to the corrugated pipes 5 one by one. In this way, multiple spray elements 3 spray water, resulting in a large spray range.

[0042] Due to the force of gravity, the corrugated pipe 5 will sag after it is extended, especially in the middle of the corrugated pipe 5. This will affect the subsequent contraction of the corrugated pipe 5. Furthermore, the sag of the corrugated pipe 5 will cause the water flow to fluctuate and oscillate. Therefore, the dishwasher also includes a lifting mechanism located between the fixed plate 21 and the corrugated pipe 5 to lift the corrugated pipe 5 upward. When the corrugated pipe 5 is extended, the lifting mechanism can be detachably connected to the corrugated pipe 5 to keep it basically horizontal and prevent it from sagping. When the corrugated pipe 5 needs to contract, the lifting mechanism releases the corrugated pipe 5 so that the corrugated pipe 5 can contract normally.

[0043] The lifting mechanism can be an existing electric robotic arm structure capable of gripping or releasing the bellows 5. In this embodiment, the lifting mechanism includes a first magnetic element disposed on the bellows 5 and a second magnetic element 7 disposed on the fixed plate 21. The second magnetic element 7 can move upward to a first position or downward to a second position. When the second magnetic element 7 is in the first position, there is no magnetic attraction between the first magnetic element and the second magnetic element 7. When the second magnetic element 7 is in the second position, the first magnetic element and the second magnetic element 7 are magnetically attracted together.

[0044] Iron powder can be added to local areas during the blow molding of the bellows 5, or magnets can be injection molded into local areas of the bellows 5.

[0045] To enable the second magnetic component 7 to move upward to the first position or downward to the second position, the dishwasher also includes a controller. The fixing plate 21 is also equipped with an electromagnet and a sensor that can sense the magnetism of the first magnetic component. The electromagnet includes the second magnetic component 7. The sensor is electrically connected to the input terminal of the controller. When the first magnetic component is close to the sensor, the sensor senses the magnetism of the first magnetic component and sends a signal to the controller. The controller controls the second magnetic component 7 of the electromagnet to move downward. At this time, the second magnetic component 7 has magnetism and is attracted to the magnetism of the first magnetic component. When the first magnetic component is far away from the sensor, the sensor does not sense the magnetism of the first magnetic component and sends a signal to the controller. The controller controls the second magnetic component 7 of the electromagnet to move upward and disengage from the first magnetic component. At this time, the magnetism of the second magnetic component 7 disappears.

[0046] In this embodiment, the sensor includes a reed switch. When the first magnetic element approaches the reed switch, the reed switch is turned on and sends a signal to the controller; when the first magnetic element moves 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 component on the bellows 5 moves directly below the reed switch. The signal is triggered and a signal is sent to the controller. The controller controls the telescopic electromagnet at the reed switch, which was originally in the retracted state, to extend the second magnetic component 7 and make the second magnetic component 7 magnetic, attracting the bellows 5 below it.

[0049] The movable plate 22 retracts backward, and the first magnetic element on the bellows 5 moves away from directly below the reed switch. This triggers a signal to the controller, which then controls the second magnetic element 7 of the electromagnet at the reed switch to switch from being magnetic to being non-magnetic and quickly retracts. In this way, the bellows 5 can be compressed smoothly, and the movable plate 22 will not interfere with or collide with the second magnetic element 7.

[0050] Each time the reed switch signal is triggered, the electromagnet's action is based on its previous action. For example, if the previous signal triggered the second magnetic element 7 to extend and become magnetic, then the next signal trigger will cause it to lose its magnetism and retract. In this way, the movement of the movable plate 22 back and forth controls whether the electromagnet attracts or "releases" the bellows 5.

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

[0052] The electromagnet uses an existing structure, and the electrical connections between the reed switch sensor and the controller, and between the controller and the electromagnet, can all use existing technologies.

[0053] As can be seen above, during the forward and backward movement of the movable plate 22, signals can be continuously triggered to control the up and down extension and retraction and whether the second magnetic component 7 of the electromagnet is connected (it has magnetism after being connected), that is, to achieve the purpose of attracting or "releasing" the bellows 5. In this way, the bellows 5 can always be kept horizontal and not drooping, 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 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.
