[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 dispensing body 1 and a pushing device inside the dispensing body 1. The dispensing body 1 includes a driver 2, a crank 3, and a push rod 4. The driver 2 drives one end of the crank 3, and the other end of the crank 3 is connected to one end of the push rod 4. The dispensing body 1 is provided with a conveying channel 5 and a discharging channel 6. Solid detergent 19 is stored in the conveying channel 5. The driver 2 drives the crank 3 to rotate, and the crank 3 drives the push rod 4 to move laterally reciprocally. When the crank 3 drives the push rod 4 to move laterally in the first direction A, the push rod 4 pushes the solid detergent 19 in the conveying channel 5 laterally to the discharging channel 6. When the crank 3 drives the push rod 4 to move laterally in the opposite direction to the first direction A, the push rod 4 returns to the desired position.

[0027] A sliding shaft 7 is provided at the other end of the crank 3, and a sliding groove 8 is provided at one end of the push rod 4. The sliding shaft 7 is located on the sliding groove 8. When the crank 3 rotates, the push rod 4 is driven to reciprocate laterally through the cooperation of the sliding shaft 7 and the sliding groove 8. When the push rod 4 reciprocates laterally, the sliding shaft 7 slides back and forth on the sliding groove 8. When the driver 2 drives the crank 3 to rotate half a turn, the crank 3 drives the push rod 4 to move laterally in the first direction A to the maximum position, such as... Figure 4As shown, after push rod 4 moves laterally to its maximum position in the first direction A, when driver 2 drives crank 3 to rotate half a turn again (in the same or opposite direction as before), crank 3 drives push rod 4 to move laterally in the opposite direction to the first direction A, and push rod 4 returns to the desired position. Figure 3 As shown.

[0028] A micro switch 9 is installed inside the feeding body 1, and a pressing part 10 is installed on the push rod 4. When the push rod 4 is in the waiting position, the pressing part 10 acts on the micro switch 9. When the push rod 4 moves laterally in the first direction A, the pressing part 10 disengages from the micro switch 9. When the push rod 4 returns to the waiting position, the pressing part 10 acts on the micro switch 9 again to complete one cycle.

[0029] The feeding body 1 is equipped with a control board 11, and a micro switch 9 is mounted on the control board 11. The control board 11 is electrically connected to the driver 2 and the micro switch 9 respectively. When the pressing part 10 acts on the micro switch 9 again, the control board 11 controls the driver 2 to stop working.

[0030] The micro switch 9 is provided with a trigger part 20. When the push rod 4 is in the waiting position, the pressing part 10 acts on the trigger part 20.

[0031] The other end of the push rod 4 is provided with a notch 12 for receiving solid detergent 19. The bottom of the notch 12 is hollowed out, and a pushing part 13 is provided on one side of the notch 12. When the push rod 4 moves laterally in the first direction A, the pushing part 13 pushes the solid detergent 19 in the notch 12 laterally onto the discharge channel 6. Due to the hollowed-out design at the bottom of the notch 12, the solid detergent 19 will fall down onto the discharge channel 6.

[0032] A limiting part 14 is provided on the other side of the notch 12. The solid detergent 19 in the notch 12 is limited between the pushing part 13 and the limiting part 14, which can prevent the solid detergent 19 from moving when the pushing part 13 pushes the solid detergent 19.

[0033] The feeding body 1 is provided with a receiving part 15, which is located at the bottom of the conveying channel 5. The push rod 4 is provided with a support part 16. Solid detergent 19 is arranged vertically on the conveying channel 5. When the push rod 4 is in the waiting position, the solid detergent 19 at the bottom of the conveying channel 5 (i.e., the solid detergent 19 at the lowest end of the conveying channel 5) is placed on the receiving part 15 and located in the notch 12. After the push rod 4 moves laterally in the first direction A, the solid detergent 19 at the bottom of the conveying channel 5 is placed on the receiving part 15. On the support part 16, after the push rod 4 pushes one solid detergent 19 at the bottom of the conveying channel 5 to the discharge channel 6, the other solid detergents 19 in the conveying channel 5 will fall down. At this time, the solid detergent 19 at the bottom of the conveying channel 5 will be placed on the support part 16. When the push rod 4 returns to the waiting position, the solid detergent 19 at the bottom of the conveying channel 5 will fall into the notch 12 and be placed on the receiving part 15. At the same time, the other solid detergents 19 in the conveying channel 5 will also fall down.

[0034] The feeding body 1 is provided with a guide groove 17. The push rod 4 is slidably mounted on the guide groove 17, and the guide groove 17 restricts the push rod 4 to only move laterally back and forth.

[0035] One end of the push rod 4 is provided with a clearance groove 18 for the clearance crank 3. The sliding groove 8 is located outside the clearance groove 18. When the push rod 4 is in the undetermined position, the crank 3 is located inside the clearance groove 18. When the push rod 4 moves laterally to the maximum position in the first direction A, the crank 3 is located outside the clearance groove 18. The design of the clearance groove 18 makes the overall structure of the pusher device more compact.

[0036] The driver 2 is a unidirectional motor or a forward and reverse motor. When the driver 2 is a unidirectional motor, the driver 2 will drive the crank 3 to rotate 360 ​​degrees in a cyclic rotation (either 360 degrees in the forward rotation or 360 degrees in the reverse rotation), thereby driving the push rod 4 to move laterally back and forth. When the driver 2 is a forward and reverse motor, the driver 2 will drive the crank 3 to rotate 180 degrees in a reciprocating rotation (either 180 degrees in the forward rotation or 180 degrees in the reverse rotation), thereby driving the push rod 4 to move laterally back and forth.

[0037] The feeder also includes a feeding port 21 located above the feeding body 1, a discharge port 22 located at the bottom of the feeding body 1, and a conveying channel 23 located at the top of the feeding body 1. The upper end of the conveying channel 23 is connected to the feeding port 21, and the lower end of the conveying channel 23 is connected to the feeding body 1. The feeding port 21, the conveying channel 23, and the conveying channel 5 are connected in sequence. The discharge channel 6 is connected to the discharge port 22. After the solid detergent 19 is put into the feeder through the feeding port 21, the solid detergent 19 is stored on the conveying channel 23 and the conveying channel 5, and the solid detergent 19 is arranged vertically. When the push rod 4 pushes the solid detergent 19 located at the bottom of the conveying channel 5 to the discharge channel 6, the solid detergent 19 will fall downwards. The solid detergent 19 falls through the discharge channel 6 to the discharge port 22 and then into the inner drum of the dishwasher.

[0038] The feeding body 1 includes a first shell 24 and a second shell 25 that cover each other. A material conveying channel 5 and a material discharge channel 6 are formed between the first shell 24 and the second shell 25. A guide groove 17 is provided on the first shell 24. An inner cavity is formed between the first shell 24 and the second shell 25. A pushing device and an electric control board 11 are provided on the inner cavity.

[0039] The feeding unit 1 is installed on the door 26 of the dishwasher.
