[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-9 The solid detergent dispenser of this dishwasher includes a conveying channel 1 and a discharging channel 2. Solid detergent 5 is stored in the conveying channel 1. A pushing component 3 is movably mounted on the conveying channel 1, and a door opening / closing component 4 is movably mounted on the discharging channel 2. The pushing component 3 and the door opening / closing component 4 are linked together by a synchronization mechanism. When the pushing component 3 moves in the first direction A (i.e., forward), it pushes the solid detergent 5 from the conveying channel 1 onto the discharging channel 2. The door opening / closing component 4 moves in the second direction B (i.e., backward) and opens the discharging channel 2. When the pushing component 3 returns to its original position in the second direction B, the door opening / closing component 4 moves in the first direction A and closes the discharging channel 2. After returning to its original position in the second direction B, the pushing component 3 returns to a pending state (e.g., ...). Figure 1 and Figure 3 As shown), to prepare for the next push; the pusher component 3 is a push rod.

[0027] The synchronization mechanism includes a synchronization wheel 6, which is disposed between the pushing component 3 and the opening / closing component 4, and the synchronization wheel 6 is engaged with the pushing component 3 and the opening / closing component 4 respectively. When the pushing component 3 moves in the first direction A, it drives the opening / closing component 4 to move in the second direction B through the synchronization wheel 6. When the pushing component 3 moves in the second direction B, it drives the opening / closing component 4 to move in the first direction A through the synchronization wheel 6.

[0028] The synchronous pulley 6 is a gear, the pushing component 3 is integrally provided with a first rack 7, and the other end of the door opening and closing component 4 is integrally provided with a second rack 8. The gear meshes with the first rack 7 and the second rack 8 respectively.

[0029] The synchronization mechanism also includes a motor 9 and a transmission component. The motor 9 drives the transmission component, and the transmission component is connected in cooperation with the pushing component 3 or the door opening and closing component 4. The motor 9 drives the pushing component 3 or the door opening and closing component 4 to move in the first direction A and the second direction B respectively through the transmission component. In this embodiment, the transmission component is connected in cooperation with the pushing component 3, and the motor 9 drives the pushing component 3 to move in the first direction A and the second direction B respectively through the transmission component.

[0030] The pusher component 3 has a notch 10 at one end for receiving solid detergent 5. The bottom of the notch 10 is hollowed out, and a pusher part 11 is provided on one side of the notch 10. When the pusher component 3 moves in the first direction A, the pusher part 11 pushes the solid detergent 5 in the notch 10 onto the discharge channel 2. Due to the hollowed-out design at the bottom of the notch 10, the solid detergent 5 will fall down onto the discharge channel 2.

[0031] A limiting part 14 is provided on the other side of the notch 10. The solid detergent 5 in the notch 10 is limited between the pushing part 11 and the limiting part 14, which can prevent the solid detergent 5 from moving when the pushing part 11 pushes the solid detergent 5.

[0032] A receiving part 12 is provided below the conveying channel 1, and a support part 13 is provided on the pushing part 3. Solid detergent 5 is arranged vertically on the conveying channel 1. The solid detergent 5 at the bottom of the conveying channel 1 (i.e., the solid detergent 5 at the lowest end of the conveying channel 1) is placed on the receiving part 12 and is located in the notch 10. After the pushing part 3 moves in the first direction A, the solid detergent 5 at the bottom of the conveying channel 1 is placed on the support part 13. That is, after the pushing part 3 pushes one solid detergent 5 at the bottom of the conveying channel 1 to the discharge channel 2, the other solid detergent 5 in the conveying channel 1 will fall down. At this time, the solid detergent 5 at the bottom of the conveying channel 1 will be placed on the support part 13. When the pushing part 3 moves back to the second direction B, the solid detergent 5 at the bottom of the conveying channel 1 will fall into the notch 10 and be placed on the receiving part 12. At the same time, the other solid detergent 5 in the conveying channel 1 will also fall down.

[0033] The door opening and closing component 4 is provided with a closing part 15 at one end; when the door opening and closing component 4 moves in the first direction A, the closing part 15 moves to the discharge channel 2 to close the discharge channel 2; when the door opening and closing component 4 moves in the second direction B, the closing part 15 leaves the discharge channel 2 to open the discharge channel 2.

[0034] It also includes a first sliding groove 16 and a second sliding groove 17, with a first rack 7 slidably disposed on the first sliding groove 16 and a second rack 8 slidably disposed on the second sliding groove 17.

[0035] The transmission component is a connecting rod 18. The motor 9 drives one end of the connecting rod 18, and the other end of the connecting rod 18 is connected to the other end of the pushing component 3. The connecting rod 18 is equivalent to a crank. The motor 9 drives the connecting rod 18 to rotate, and the connecting rod 18 drives the pushing component 3 to move in the first direction A and the second direction B respectively. That is, the connecting rod 18 drives the pushing component 3 to reciprocate back and forth.

[0036] A sliding shaft 19 is provided at the other end of the connecting rod 18, and a sliding groove 20 is provided at the other end of the pushing component 3. The sliding shaft 19 is located on the sliding groove 20. When the connecting rod 18 rotates, the sliding shaft 19 and the sliding groove 20 cooperate to drive the pushing component 3 to move in the first direction A and the second direction B respectively. When the pushing component 3 moves in the first direction A and the second direction B respectively, the sliding shaft 19 slides back and forth on the sliding groove 20. When the motor 9 drives the connecting rod 18 to rotate half a turn, the connecting rod 18 drives the pushing component 3 to move to the maximum position in the first direction A. Figure 4 As shown, after the pushing component 3 moves to its maximum position in the first direction A, when the motor 9 drives the connecting rod 18 to rotate half a turn again (in the same or opposite direction as before), the connecting rod 18 drives the pushing component 3 to reset in the second direction B, and the pushing component 3 resets to the desired position, as shown. Figure 3 As shown.

[0037] The other end of the pushing component 3 is provided with a clearance groove 21 for the clearance connecting rod 18. The sliding groove 20 is located outside the clearance groove 21. When the pushing component 3 is in the waiting position, the connecting rod 18 is located inside the clearance groove 21. When the pushing component 3 moves to the maximum position in the first direction A, the connecting rod 18 is located outside the clearance groove 21. The design of the clearance groove 21 makes the overall structure of the discharge device more compact.

[0038] Motor 9 is a unidirectional motor or a forward and reverse reversible motor. When motor 9 is a unidirectional motor, it drives the connecting rod 18 to rotate 360 ​​degrees in a circular motion (either 360 degrees in the forward direction or 360 degrees in the reverse direction), thereby driving the pushing component 3 to move back and forth. When motor 9 is a forward and reverse reversible motor, it drives the connecting rod 18 to rotate 180 degrees in a reciprocating motion (either 180 degrees in the forward direction or 180 degrees in the reverse direction), thereby driving the pushing component 3 to move back and forth.

[0039] The discharge device also includes a first housing 22 and a second housing 23 that cover each other, the first housing 22 and the second housing 23 form a feeding body 24, and a conveying channel 1 and a discharge channel 2 are formed between the first housing 23 and the second housing 24.

[0040] A micro switch 25 is provided inside the feeding body 24, and a pressing part 26 is provided on the pushing part 3. When the pushing part 3 is in the waiting position, the pressing part 26 acts on the micro switch 25. When the pushing part 3 moves in the first direction A, the pressing part 26 disengages from the micro switch 25. When the pushing part 3 returns to the waiting position, the pressing part 26 acts on the micro switch 25 again to complete one cycle.

[0041] A control board 27 is installed inside the feeding body 24. A micro switch 25 is installed on the control board 27. The control board 27 is electrically connected to the motor 9 and the micro switch 25 respectively. When the pressing part 26 acts on the micro switch 25 again, the control board 27 controls the motor 9 to stop working.

[0042] The micro switch 25 is provided with a trigger part 28. When the pusher part 3 is in the waiting position, the pressing part 26 acts on the trigger part 28.

[0043] The first housing 22 is provided with a guide groove 29, and the pushing component 3 is slidably disposed on the guide groove 29. The guide groove 29 restricts the pushing component 3 to only move back and forth.

[0044] The feeder also includes a feeding port 30 located above the feeding body 24, a discharge port 31 located at the bottom of the feeding body 24, and a conveying passage 32 located at the top of the feeding body 24.
