[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0050] See also Figure 1-Figure 22 The dishwasher dispenser includes a dispenser body 1, a storage tray 2 and an electronic control mechanism. The storage tray 2 has a plurality of storage cavities 21 distributed along the circumference for placing detergent. The dispenser body 1 is movably connected to a cover body 3 that can open or close the storage cavity 21. A sensing component is provided between the cover body 3 and the dispenser body 1. The sensing component includes a first sensing part 31 provided on the cover body 3 and a second sensing part 11 provided on the dispenser body 1, corresponding to the first sensing part 31 and electrically connected to the electronic control mechanism.

[0051] The cover 3 closes the material storage cavity 21 so that the first sensing portion 31 and the second sensing portion 11 are adjacent to each other and cooperate with each other to make the sensing component conductive. At this time, the electronic control mechanism of the dishwasher can start the dishwasher normally.

[0052] The cover 3 opens the storage cavity 21 so that the first sensing part 31 and the second sensing part 11 move away from each other and the sensing component is disconnected. At this time, the electronic control mechanism cannot start the dishwasher. That is, when the cover 3 is not fully covered with the dispenser body 1, the electronic control mechanism of the dishwasher cannot start the dishwasher.

[0053] The cover 3 closes the storage cavity 21 so that the first sensing part 31 and the second sensing part 11 are adjacent to each other and cooperate to make the sensing component conductive. The cover 3 opens the storage cavity 21 so that the first sensing part 31 and the second sensing part 11 are separated from each other and the sensing component is disconnected. By setting the sensing component, the dishwasher will not be accidentally started when the cover and the dispenser body are not closed in place.

[0054] The dispenser body 1 is connected to an elastic component, and the cover body 3 is provided with a positioning portion 32 that can slide with the elastic component. The elastic component can slide relative to the cover body 3 and the positioning portion 32 to connect or separate the positioning portion 32 with the elastic component. When the cover body 3 closes the storage cavity 21, the elastic component is connected and matched with the positioning portion 32, so that the cover body 3 is connected and fixed to the dispenser body 1. The elastic component can improve the connection strength between the cover body 3 and the dispenser body 1 when the storage cavity 21 is covered. The elastic component can also be deformed to make it easier for the user to separate the cover body 3 from the dispenser body 1 when the storage cavity 21 needs to be opened. At the same time, the convenience of the user adding detergent and the connection strength between the cover body 3 and the dispenser body 1 after covering are taken into account, thereby reducing the chance of liquid flowing into the storage cavity 21 during the operation of the dishwasher, making the detergent in the storage cavity 21 not easily affected by moisture, and improving the cleaning effect of the detergent when used.

[0055] Furthermore, the first sensing part 31 is a magnet block, and the second sensing part 11 is a Hall switch. The Hall switch has a sensing end. The cover body 3 closes the storage cavity 21 to move the magnet block to a position adjacent to the front side of the sensing end of the Hall switch. When the magnet block approaches the sensing end of the Hall switch, the charge inside the Hall switch is affected by the magnetic field to form an electric potential difference voltage signal. The voltage signal is converted into a control signal through the internal circuit of the Hall switch and fed back to the electronic control mechanism of the dishwasher.

[0056] Furthermore, the cover body 3 and the dispenser main body 1 are respectively provided with a first snap portion 33 and a second snap portion 12. When the cover body 3 closes the storage chamber 21, the first snap portion 33 and the second snap portion 12 are engaged with each other to fix the cover body 3 and the dispenser main body to each other, further improving the stability of the cover body 3 after connection with the dispenser main body 1, and enabling the cover body 3 to quickly open or close the storage chamber 21.

[0057] Preferably, a first guide slope 331 is provided on the lower side of the first snap portion 33, and a second guide slope 121 is provided on the upper side of the second snap portion 12. The first snap portion 33 and / or the second snap portion 12 can be elastically deformed. When the cover body 3 closes the storage chamber 21, the first guide slope 331 and the second guide slope 121 slide together to elastically deform the first snap portion 33 and / or the second snap portion 12. The first guide slope 331 and the second guide slope 121 are separated to elastically reset the first snap portion 33 and / or the second snap portion 12. The first snap portion 33 and the second snap portion 12 are engaged with each other. The cooperation between the first guide slope 331 and the second guide slope 121 can improve the smoothness of the process of the cover body 3 and the dispenser body 1 being put into place.

[0058] Furthermore, the elastic component includes a ball spring 41 and a movable ball 42. The ball spring 41 can push the movable ball 42 to abut against the cover body 3 or the positioning portion 32. The positioning portion 32 is in an arc shape corresponding to the shape of the movable ball 42. When the cover body 3 closes the storage chamber 21, the movable ball 42 can be tightly attached to the positioning portion 32 under the action of the ball spring 41, so that the cover body 3 and the dispenser body 1 have a better connection strength, and the cover body 3 is not easy to accidentally open the storage chamber 21. When the user needs to open the cover body 3, since the surfaces of the movable ball 42 and the positioning portion 32 are in an arc shape, the user can more easily make the movable ball 42 and the positioning portion 32 slide relative to each other after applying a pulling force to the cover body 3, and at the same time deform the ball spring 41, so that the cover body 3 can be opened relatively conveniently.

[0059] Preferably, a cover guide slope 34 is provided on the inner lower side of the cover 3, corresponding to a position below the locking portion 32. The cover guide slope 34 is arranged to be inclined outward from top to bottom, and the movable ball 42 can slide with the cover guide slope 34. When the cover 3 needs to close the storage chamber 21, the process from the cover 3 initially contacting the movable ball 42 to the movable ball 42 connecting with the locking portion 32 can be improved.

[0060] Preferably, the dispenser body 1 is provided with a spring retaining groove 13, which extends horizontally and has an open end corresponding to the outer side of the dispenser body 1. The ball spring 41 abuts the spring retaining groove 13 horizontally, and the movable ball 42 abuts the opening of the spring retaining groove 13. The diameter of the movable ball 42 is larger than the diameter of the opening of the spring retaining groove 13, allowing the movable ball 42 to partially extend outward through the opening of the spring retaining groove 13. The spring retaining groove 13 serves to retain the ball spring 41 and the movable ball 42, preventing them from accidentally falling off during use and improving the precision of the connection between the movable ball 42 and the locking portion 32. The movable ball 42 slides with the opening of the spring retaining groove 13 and the ball spring 41, respectively. The movable ball 42 can rotate relative to the opening of the spring retaining groove 13 and the ball spring 41, ensuring smoother contact between the cover 3 or the locking portion 32 and the movable ball 42.

[0061] Furthermore, the cover body 3 is fixedly connected to the cover sealing ring 5, and the cover sealing ring 5 is fixedly connected to the cover body 3. When the cover body 3 closes the storage cavity 21, the cover sealing ring 5 is tightly fitted with the dispenser body 1 and the cover body 3 respectively. When the cover body 3 opens the storage cavity 21, the cover sealing ring 5 slides and fits with the dispenser body 1 until the two are separated from each other, so that the sealing between the cover body 3 and the dispenser body 1 is better when the storage cavity 21 is closed, thereby further reducing the chance of liquid flowing into the storage cavity 21 during the operation of the dishwasher, making the detergent in the storage cavity 21 not easily affected by moisture, and improving the cleaning effect of the detergent when used.

[0062] Preferably, a positioning edge 35 is provided on the side of the cover body 3 facing the storage chamber 21, and the cover sealing ring 5 has a positioning groove 51 corresponding to the positioning edge 35. The positioning edge 35 and the positioning groove 51 are plugged in and tightly fitted together to improve the connection strength between the cover sealing ring 5 and the cover body 3, and prevent the cover sealing ring 5 from accidentally falling off during movement.

[0063] Preferably, a mounting slot 36 is provided on the cover body 3 at a position adjacent to the positioning edge 35, and a mounting flange 52 corresponding to the mounting slot 36 is provided on the cover sealing ring 5. The mounting flange 52 is plugged into and tightly fits with the mounting slot 36, further improving the connection strength between the cover sealing ring 5 and the cover body 3.

[0064] Preferably, a recessed platform 37 is provided on the cover body 3, and the recessed platform 37 is concave on the side facing away from the storage cavity 21. The recessed platform 37 protrudes toward the storage cavity 21 and is adjacent to the upper end of the storage cavity 21. The recessed platform 37 can improve the overall structural strength of the cover body 3. At the same time, the recessed platform 37 can also have a certain anti-falling effect on the detergent in the storage cavity 21, so that the detergent can be stored more stably in the storage cavity 11.

[0065] Preferably, a plurality of ribs 38 are circumferentially distributed between the concave portion 37 and the outer side of the mounting slot 36. The ribs 38 are arranged radially along the concave portion 37 to further enhance the structural strength of the cover 3 and prevent the cover 3 from being deformed by stress.

[0066] Furthermore, the distributor body 1 has a discharge port 14, and the storage tray 2 can rotate to make different storage cavities 21 pass through the positions corresponding to the discharge port 14 in sequence. The distributor body 1 is connected to a movable part 6 that can open or close the discharge port 14. A motor 7 and a transmission turntable 71 are provided in the distributor body 1. The transmission turntable 71 is fixedly connected to the output end of the motor 7. The transmission turntable 71 is provided with a transmission mechanism that can respectively cooperate with the storage tray 2 or the movable part 6 for transmission. The transmission mechanism rotates around the transmission turntable 71 to make the storage tray 2 rotate or the movable part 6 open the discharge port 14. By arranging the transmission mechanism on the transmission turntable 71, the motor 7 can achieve the driving effect of the storage tray 2 and the movable part 6, which simplifies the structure of driving the storage tray 2 and the movable part 6, reduces the production and processing costs of the product, and is conducive to improving the competitiveness of the product.

[0067] Preferably, the discharge port 14 and the dispenser body 1 are integrally formed, which simplifies the overall structure of the dispenser body 1 .

[0068] Preferably, the transmission mechanism includes a convex column portion 711, and the storage tray 2 is fixedly connected to a tooth rack 72, and a number of concave tooth grooves 721 are evenly distributed on the tooth rack 72, and each storage cavity 21 corresponds to each concave tooth groove 721. When the convex column portion 711 is linked with the concave tooth groove 721, the tooth rack 72 and the storage tray 2 rotate. When the convex column portion 711 is separated from the concave tooth groove 721, the tooth rack 72 and the storage tray 2 stop rotating, which can prevent the movable part 6 from accidentally opening the discharge port 14 before the storage cavity 21 rotates into place. That is, each time the movable part 6 opens the discharge port 14, the corresponding storage cavity 21 will move to the preset position before, so that the detergent in the corresponding storage cavity 21 can be discharged smoothly.

[0069] The protruding column 711 drives the tooth rack 72 through a single concave tooth groove 721 to rotate at an angle equivalent to the angle between the adjacent storage chambers 21, so that each storage chamber 21 can pass through the corresponding discharge port 14 one by one, so that the detergent in each storage chamber 21 can be discharged smoothly.

[0070] Preferably, the transmission mechanism also includes a first transmission tooth 73, and a second transmission tooth 61 corresponding to the first transmission tooth 73 is provided on the movable part 6. The positive rotation of the transmission turntable 71 can enable the first transmission tooth 73 to push the movable part 6 to open the discharge port 14 through the second transmission tooth 61. When the first transmission tooth 73 rotates with the transmission turntable 71 to the position corresponding to the second transmission tooth 61, the effect of the motor 7 driving the movable part 6 to open the discharge port 14 can be achieved.

[0071] The transmission turntable 71 rotates in the forward direction one circle, so that the action of the boss portion 711 pushing the storage tray 2 to rotate and the action of the movable part 6 to open the discharge port 14 are completed separately in sequence. Specifically, during the process of the transmission turntable 71 rotating in the forward direction one circle, the boss portion 711 will first act on the concave tooth groove 721, thereby pushing the storage tray 2 to rotate a certain angle, so that the storage cavity 21 is aligned with the discharge port 14, and finally the first transmission tooth 73 and the second transmission tooth 61 act to make the movable part 6 open the discharge port 14, so that the detergent in the storage cavity 21 is discharged outward.

[0072] The movable member 6 is connected to a return spring 62. The first transmission tooth 73 pushes the movable member 6 through the second transmission tooth 61 to open the discharge port 14, causing the return spring 62 to deform. The return spring 62 then resets the movable member 6 and closes the discharge port 14. When the transmission turntable 71 rotates until the first transmission tooth 73 stops acting on the second transmission tooth 61, the return spring 62 resets to ensure that the movable member 6 maintains the closed state of the discharge port 14, preventing accidental discharge of detergent.

[0073] Furthermore, the movable member 6 is provided at the vertical bottom of the dispenser body 1. When the movable member 6 opens the discharge port 14, the detergent in the storage chamber 21 can be discharged outward by gravity, further simplifying the overall structure of the dispenser.

[0074] A movable sealing ring 63 is provided on the side of the movable part 6 facing the discharge port 14. The movable sealing ring 63 is tightly fitted with the movable part 6 and the dispenser body 1 respectively. A first sealing buckle portion 631 and a second sealing buckle portion 64 with an L-shaped cross-section are respectively provided on the movable sealing ring 63 and the movable part 6. The first sealing buckle portion 631 and the second sealing buckle portion 64 are buckled with each other and tightly fitted, thereby improving the connection stability between the movable sealing ring 63 and the movable part 6 and preventing the movable sealing ring 63 from accidentally falling off the movable part 6.

[0075] A buffer portion 632 is also provided on the movable sealing ring 63. The cross-section of the buffer portion 632 is N-shaped. The buffer portion 632 can be elastically deformed. The buffer portion 632 is tightly matched with the movable part 6 and the distributor body 1 respectively to avoid a hard connection between the movable sealing ring 63 and the distributor body 1, thereby reducing the wear of the movable sealing ring 63 while ensuring the sealing effect of the two.

[0076] Furthermore, the electric control mechanism includes a control main board 8 electrically connected to the motor 7, and the control main board 8 is electrically connected to the touch switch 81. The boss portion 711 contacts or separates from the touch switch 81 by revolving around the center of the transmission turntable 71. The control main board 8 can control the motor 7 to drive the transmission turntable 71 and the boss portion 711 to rotate so that the boss portion 711 is separated from the touch switch 81 until the boss portion 711 revolves one circle and contacts the touch switch 81 again while the motor 7 stops rotating. The boss portion 711 physically contacts the touch switch 81 so that the control main board 8 receives the signal and controls the motor 7 again, thereby simplifying the electrical control structure between the control main board 8 and the motor 7 and improving the reliability of the equipment operation.

[0077] In the initial state, the boss portion 711 contacts the touch switch 81. When the motor needs to be started, the control board 8 sends a start signal to the motor 7. The motor 7 starts to start, causing the transmission turntable 71 to drive the boss portion 711 to rotate. When the boss portion 711 makes one revolution and contacts the touch switch 81 again, the control cardboard sends a shutdown signal to the motor 7, and the transmission turntable 71 stops rotating.

[0078] Furthermore, the control main board 8 is arranged adjacent to the transmission turntable 71, and the touch switch 81 is connected and fixed to the control main board 8. No additional wires are required between the touch switch 81 and the control main board 8, and no additional installation position is required for the touch switch 81 in the distributor, which simplifies the electrical connection structure between the touch switch 81 and the control main board 8.

[0079] The touch switch 81 includes a switch body 811 and a switch contact 812. The switch contact 812 can be retracted inward or extended outward relative to the switch body 811.
