Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, and particularly relates to a feeding structure of a dishwasher dispenser. Background Art

[0002] Dishwashers usually have a dispenser for dispensing detergent. The dispenser generally includes a storage tray, and several storage cavities are arranged on the storage tray. When the dispenser is in use, the detergent needs to be pre-placed in the storage cavities in the dispenser, and then by rotating the storage tray, the detergents in different storage cavities can be successively dispensed into the dishwasher by rotation. An outlet is arranged on the dispenser. When the corresponding storage cavity rotates to the position of the outlet, the valve at the outlet position opens so that the detergent in the corresponding storage cavity can be discharged outwards.

[0003] The rotation of the storage tray and the opening of the outlet require two sets of drive systems, resulting in a relatively complex overall structure of the dispenser and a relatively high manufacturing cost, which is not conducive to enhancing the product competitiveness.

[0004] Therefore, further improvement is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a feeding structure of a dishwasher dispenser, which simplifies the structures for driving the storage tray and the movable part, reduces the production and processing cost of the product, and is conducive to enhancing the product competitiveness.

[0006] The purpose of the utility model is realized as follows:

[0007] A feeding structure of a dishwasher dispenser, including a dispenser main body and a storage tray movably connected to the dispenser main body. The dispenser main body has an outlet. A plurality of storage cavities for storing detergent are circumferentially distributed in the storage tray. The storage tray can rotate itself so that different storage cavities can successively pass through the position corresponding to the outlet. The dispenser main body is connected with a movable part that can open or close the outlet. A motor and a transmission turntable are arranged in the dispenser main body. The transmission turntable is fixedly connected to the output end of the motor. A transmission mechanism that can be selectively in transmission cooperation with the storage tray or the movable part is arranged on the transmission turntable. The transmission mechanism makes the storage tray rotate itself or the movable part open the outlet by revolving around the transmission turntable.

[0008] As a specific scheme, the transmission mechanism includes a convex column part. A tooth rack is fixedly connected to the storage tray. A plurality of concave tooth grooves are evenly distributed on the tooth rack. Each storage cavity corresponds to each concave tooth groove one by one. When the convex column part is linked with the concave tooth groove, the tooth rack and the storage tray make a self-rotation movement. When the convex column part is separated from the concave tooth groove, the tooth rack and the storage tray stop rotating. The angle by which the convex column part drives the tooth rack to rotate through a single concave tooth groove is equivalent to the included angle between adjacent storage cavities.

[0009] As a specific solution, the transmission mechanism further includes a first transmission gear, and a second transmission gear corresponding to the first transmission gear is provided on the movable member. When the transmission turntable rotates forward, the first transmission gear can push the movable member through the second transmission gear to open the discharge port. The action of the convex column portion pushing the storage tray to rotate and the action of the movable member opening the discharge port are sequentially and separately completed when the transmission turntable rotates forward one revolution around the center.

[0010] As a specific solution, the movable member is connected with a spring. When the first transmission gear pushes the movable member through the second transmission gear to open the discharge port, the spring is deformed, and the spring returns to its original position to push the movable member to close the discharge port.

[0011] As a specific solution, a limiting groove is provided inside the dispenser main body, and the movable member can slide along the extension direction of the limiting groove. Positioning columns and positioning holes corresponding to the spring are respectively provided on the limiting groove and the movable member. One end of the spring is sleeved on the positioning column, and the other end of the spring extends into the positioning hole. When the movable member opens the discharge port, the positioning column is inserted into the positioning hole.

[0012] As a specific solution, one section of the movable member and the limiting groove near the discharge port are respectively in corresponding isosceles trapezoid shapes, and their widths decrease along the direction of the spring returning to its original position.

[0013] One side of the limiting groove perpendicular to its length direction is open and is detachably connected with a baffle. The baffle and the limiting groove are installed and fixed through a buckle mechanism. A guiding groove corresponding to the movable member is provided on the baffle, and the movable member can be slidably matched with the guiding groove.

[0014] As a specific solution, the motor is electrically connected with a control main board, and the control main board is electrically connected with a touch switch. The convex column portion makes a revolution around the center of the transmission turntable to contact or separate from the touch switch. The control main board can control the motor to drive the transmission turntable and the convex column portion to rotate so that the convex column portion separates from the touch switch until the convex column portion makes one revolution around the center and contacts the touch switch again and the motor stops rotating.

[0015] As a specific solution, the movable member is arranged at the vertical bottom of the dispenser main body. A sealing ring is provided on one side of the movable member facing the discharge port. The sealing ring is closely matched with the movable member and the dispenser main body respectively. First sealing buckle portions and second sealing buckle portions with an L-shaped cross section are respectively provided on the sealing ring and the movable member. The first sealing buckle portion and the second sealing buckle portion are buckled with each other and are closely matched. A buffer portion is further provided on the sealing ring. The cross section of the buffer portion is N-shaped, and the buffer portion can be elastically deformed. The buffer portion is closely matched with the movable member and the dispenser main body respectively.

[0016] As a specific solution, the dispenser body is movably connected with a cover body capable of opening or closing the material storage cavity. An elastic component is connected to the dispenser body, and a positioning part capable of slidingly cooperating with the elastic component is provided on the cover body. The elastic component can slide relative to the cover body and the positioning part to connect or separate the positioning part from the elastic component. When the cover body closes the material storage cavity, the elastic component is connected and cooperated with the positioning part, so that the cover body is fixedly connected to the dispenser body.

[0017] As a specific solution, the elastic component includes a ball spring and a movable ball. The ball spring can push the movable ball to abut against the cover body or the positioning part, and the positioning part is in an arc shape corresponding to the shape of the movable ball.

[0018] The beneficial effects of the present utility model are as follows:

[0019] By providing a transmission mechanism on the driving turntable, the motor can achieve the driving effect on the material storage tray and the movable part, simplifies the structure for driving the material storage tray and the movable part, reduces the production and processing cost of the product, and is beneficial to improving the competitiveness of the product.

[0038] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] Refer to Figures 1 - 18 , the feeding structure of the dishwasher dispenser, the dispenser main body 1 and the storage tray 2 movably connected to the dispenser main body 1. The dispenser main body 1 has a discharge port 11. A plurality of storage cavities 21 for storing detergent are circumferentially distributed in the storage tray 2. The storage tray 2 can rotate itself to make different storage cavities 21 sequentially pass through the position corresponding to the discharge port 11. The dispenser main body 1 is connected with a movable member 3 that can open or close the discharge port 11. A motor 41 and a transmission turntable 42 are arranged in the dispenser main body 1. The transmission turntable 42 is fixedly connected to the output end of the motor 41. A transmission mechanism that can selectively transmit power to either the storage tray 2 or the movable member 3 is arranged on the transmission turntable 42. The transmission mechanism rotates around the transmission turntable 42 to make the storage tray 2 rotate itself or the movable member 3 open the discharge port 11. By arranging the transmission mechanism on the transmission turntable 42, the motor 41 can achieve the driving effect on the storage tray 2 and the movable member 3, simplifies the structure for driving the storage tray 2 and the movable member 3, reduces the production and processing cost of the product, and is beneficial to improving the competitiveness of the product.

[0040] Preferably, the discharge port 11 and the dispenser body 1 are integrally formed structures, which simplifies the overall structure of the dispenser body 1.

[0041] Furthermore, the transmission mechanism includes a convex column portion 421. The storage tray 2 is fixedly connected with a toothed rack 22. A number of concave tooth grooves 221 are evenly distributed on the toothed rack 22. Each storage cavity 21 corresponds to each concave tooth groove 221 one by one. When the convex column portion 421 is linked with the concave tooth groove 221, the toothed rack 22 and the storage tray 2 make a self-rotation movement. When the convex column portion 421 is separated from the concave tooth groove 221, the toothed rack 22 and the storage tray 2 stop self-rotating. This can prevent the movable member 3 from accidentally opening the discharge port 11 before the storage cavity 21 rotates to the proper position. That is, every time the movable member 3 opens the discharge port 11, a corresponding storage cavity 21 has previously moved to a preset position, enabling the detergent in the corresponding storage cavity 21 to be smoothly discharged outwards.

[0042] The angle by which the convex column portion 421 drives the toothed rack 22 to rotate through a single concave tooth groove 221 is equivalent to the included angle between adjacent storage cavities 21, enabling each storage cavity 21 to sequentially pass through the position corresponding to the discharge port 11 one by one, so that the detergent in each storage cavity 21 can be smoothly discharged outwards.

[0043] Furthermore, the transmission mechanism further includes a first transmission gear 422. A second transmission gear 31 corresponding to the first transmission gear 422 is provided on the movable member 3. When the transmission turntable 42 rotates forward, the first transmission gear 422 can push the movable member 3 to open the discharge port 11 through the second transmission gear 31. When the first transmission gear 422 rotates to the position corresponding to the second transmission gear 31 along with the transmission turntable 42, the effect of the motor 41 driving the movable member 3 to open the discharge port 11 can be achieved.

[0044] The actions of the convex column portion 421 pushing the storage tray 2 to rotate and the movable member 3 opening the discharge port 11 are sequentially and separately completed when the transmission turntable 42 rotates forward one week. Specifically, during the process of the transmission turntable 42 rotating forward one week, the convex column portion 421 will first act in the concave tooth groove 221, thereby pushing the storage tray 2 to rotate a certain angle to align the storage cavity 21 with the discharge port 11. Finally, the first transmission gear 422 and the second transmission gear 31 act on each other to make the movable member 3 open the discharge port 11, enabling the detergent in the storage cavity 21 to be discharged outwards.

[0045] Furthermore, the movable member 3 is connected with a spring 5. When the first transmission gear 422 pushes the movable member 3 to open the discharge port 11 through the second transmission gear 31, the spring 5 is deformed. When the spring 5 resets, it pushes the movable member 3 to close the discharge port 11. When the transmission turntable 42 rotates until the first transmission gear 422 stops acting on the second transmission gear 31, the spring 5 can ensure that the movable member 3 maintains the closed state of the discharge port 11 through resetting, avoiding accidental discharge of the detergent.

[0046] Further, a limiting groove 13 is provided inside the dispenser body 1, and the movable member 3 can slide along the extension direction of the limiting groove 13, which can improve the stability of the movable member 3 during the movement process and reduce the chance of its deviation.

[0047] A positioning post 131 corresponding to the spring 5 and a positioning hole 32 are respectively provided on the limiting groove 13 and the movable member 3. One end of the spring 5 is sleeved on the positioning post 131, and the other end of the spring 5 extends into the positioning hole 32. When the movable member 3 opens the discharge port 11, the positioning post 131 is inserted into the positioning hole 32. The cooperation between the positioning hole 32 and the positioning post 131 can not only improve the connection stability of the spring 5 but also improve the movement stability of the movable member 3.

[0048] Further, a section of the movable member 3 and the limiting groove 13 near the discharge port 11 are respectively in corresponding isosceles trapezoid shapes, and their widths decrease along the direction of the spring 5 resetting. When the spring 5 pushes the movable member 3 to reset, the chance of the movable member 3 getting stuck can be reduced, and the operation stability of the device can be improved.

[0049] One side of the limiting groove 13 perpendicular to its length direction is open and detachably connected with a baffle 132. The baffle 132 and the limiting groove 13 are installed and fixed through a buckle mechanism. A guiding groove 1321 corresponding to the movable member 3 is provided on the baffle 132, and the movable member 3 can slide and cooperate with the guiding groove 1321. The baffle 132 can further improve the operation stability of the movable member 3. At the same time, the detachable structure of the baffle 132 can make it easier to install components such as the spring 5 in the limiting groove 13 during the installation process, and the buckle mechanism can enable the baffle 132 and the limiting groove 13 to be quickly disassembled and assembled, improving the assembly efficiency.

[0050] Further, the motor 41 is electrically connected to a control main board 6, the control main board 6 is electrically connected to a touch switch 61, and the convex column part 421 contacts or separates from the touch switch 61 by making a revolution around the center of the transmission turntable 42. The control main board 6 can control the motor 41 to drive the transmission turntable 42 and the convex column part 421 to rotate so that the convex column part 421 separates from the touch switch 61 until the convex column part 421 makes a full revolution and contacts the touch switch 61 again and the motor 41 stops rotating. The convex column part 421 enables the control main board 6 to receive signals by physically contacting the touch switch 61 and then controls the motor 41 again, simplifying the electrical control structure between the control main board 6 and the motor 41 and improving the operation reliability of the device.

[0051] In the initial state, the convex column portion 421 is in contact with the touch switch 61. When the motor 41 needs to be started, the control main board 6 sends a start signal to the motor 41. The motor 41 starts to operate, causing the transmission turntable 42 to drive the convex column portion 421 to rotate. When the convex column portion 421 makes one full revolution and comes into contact with the touch switch 61 again, the control main board 6 sends a shutdown signal to the motor 41, and the transmission turntable 42 stops rotating.

[0052] The control main board 6 does not need to be provided with relatively complex structures such as a timing module inside, which simplifies the electrical control structure between the control main board 6 and the motor 41. Since the shutdown of the driving motor 41 is completed through the physical contact between the convex column portion 421 and the touch switch 61, that is, the angle of rotation of the storage tray 2 is the same every time the motor 41 starts and shuts down, the rotation accuracy of the storage tray 2 can be improved each time.

[0053] Furthermore, the movable member 3 is provided at the vertical bottom of the dispenser main body 1. When the movable member 3 opens the discharge port 11, the detergent in the storage cavity 21 can be discharged outward under the action of gravity, further simplifying the overall structure of the dispenser.

[0054] A sealing ring 7 is provided on one side of the movable member 3 facing the discharge port 11. The sealing ring 7 is closely fitted with the movable member 3 and the dispenser main body 1 respectively. The sealing ring 7 and the movable member 3 are respectively provided with a first sealing buckle portion 71 and a second sealing buckle portion 33 with an L-shaped cross-section. The first sealing buckle portion 71 and the second sealing buckle portion 33 are buckled with each other and closely fitted, improving the connection stability between the sealing ring 7 and the movable member 3 and preventing the sealing ring 7 from accidentally falling off the movable member 3.

[0055] The sealing ring 7 is also provided with a buffer portion 72. The buffer portion 72 has an N-shaped cross-section and can elastically deform. The buffer portion 72 is closely fitted with the movable member 3 and the dispenser main body 1 respectively, avoiding the occurrence of a hard connection between the sealing ring 7 and the dispenser main body 1 and reducing the wear of the sealing ring 7 while ensuring the sealing effect between the two.

[0056] Furthermore, the dispenser main body 1 is movably connected with a cover body 8 that can open or close the storage cavity 21. An elastic component is connected to the dispenser main body 1, and a positioning portion 81 that can slide with the elastic component is provided on the cover body 8. The elastic component can slide relative to the cover body 8 and the positioning portion 81 to connect or separate the positioning portion 81 from the elastic component. When the cover body 8 closes the storage cavity 21, the elastic component is connected and cooperated with the positioning portion 81, making the cover body 8 fixedly connected to the dispenser main body 1. The elastic component can improve the connection strength between the cover body 8 and the dispenser main body 1 when the cover body 8 closes the storage cavity 21. The elastic component can also be deformed to make it easier for the user to separate the cover body 8 from the dispenser main body 1 when the storage cavity 21 needs to be opened, taking into account both the convenience of the user adding detergent and the connection strength between the cover body 8 and the dispenser main body 1 after being closed.

[0057] Further, the elastic component includes a ball spring 91 and a movable ball 92. The ball spring 91 can push the movable ball 92 to abut against the cover body 8 or the in-place portion 81. The in-place portion 81 is in an arc shape corresponding to the shape of the movable ball 92. When the cover body 8 closes the storage cavity 21, the movable ball 92 can closely adhere to the in-place portion 81 under the action of the ball spring 91, so that there is a good connection strength between the cover body 8 and the dispenser body 1, and the cover body 8 is not easily opened accidentally to the storage cavity 21.

[0058] The above embodiments are only the preferred solutions of the present invention, and the present invention may also have other implementation solutions. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope set by the claims of this application.
