Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher solid detergent dispenser with a material discharge detection device. Background Technology

[0002] Dishwashers are increasingly popular due to their advantages such as good cleaning performance, food disinfection, and time and labor savings. Dishwashers require detergent, which can be solid or liquid. For dishwashers using solid detergent, the detergent dispenser is typically located on the door, with a dispensing inlet and an outlet at the top and bottom. Users can add detergent through the dispensing inlet. Inside the dispenser, there is a channel for storing the detergent and a pushing device. When the pushing device is working, it pushes the detergent in the channel above the outlet, where it falls into the dishwasher's inner tub. While the dispenser is in use, the user cannot see the status of the detergent stored in the channel. If the detergent is used up and the user hasn't added more, the pushing device will continue to operate, wasting energy.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-8 This dishwasher solid detergent dispenser with a drop detection device includes a dispensing body 1, a conveying channel 2 and a discharge channel 3 inside the dispensing body 1, a pushing device 4 between the conveying channel 2 and the discharge channel 3, the pushing device 4 being used to push the solid detergent 5 on the conveying channel 2 to the discharge channel 3, and a drop detection device 6 for detecting the drop of solid detergent 5 being installed on the conveying channel 2 and the discharge channel 3, the drop detection device 6 being communicatively connected to the pushing device 4.

[0026] Solid detergent 5 is arranged vertically on the conveying channel 2. When the dropping detection device 6 is set in the conveying channel 2, it is located at the height of the second to last solid detergent 5 at the bottom of the conveying channel 2. When there is only one solid detergent 5 left on the conveying channel 2, the dropping detection device 6 does not detect the solid detergent 5 falling. Then the pushing device 4 will push the remaining solid detergent 5 to the discharge channel 3. After the dropping detection device 6 does not detect the solid detergent 5 falling, the pushing device 4 can push the solid detergent 5 again, that is, the dishwasher can use solid detergent 5 again.

[0027] The material dropping detection device 6 is respectively installed on both sides of the material conveying channel 2 and the material dropping detection device 6 is respectively installed on both sides of the material discharge channel 3. This structure can ensure effective detection of the falling solid detergent 5.

[0028] The material discharge detection device 6 includes a circuit board 7 and a detection component 8. Mounting slots 9 are provided on both sides of the material conveying channel 2 and the material discharge channel 3. The circuit board 7 is mounted on the mounting slots 9, and the detection component 8 is mounted on the circuit board 7.

[0029] Through holes 10 are provided on both sides of the material conveying channel 2 and the material discharging channel 3. The material conveying channel 2 is connected to the corresponding through hole 10, and the material discharging channel 3 is connected to the corresponding through hole 10. The detection component 8 is provided with a detection part 11 for detecting the falling solid detergent 5. The detection part 11 is located on the through hole 10. This structure ensures that the detection device 6 can accurately detect the falling solid detergent 5. The detection part 11 is a detection head.

[0030] The material feeding detection device 6 is a light sensor, such as an infrared light sensor.

[0031] An electronic control board 12 is installed inside the feeding body 1. The electronic control board 12 is electrically connected to the material dropping detection device 6 and the material pushing device 4 respectively. When the material dropping detection device 6 detects the solid detergent 5 falling, it sends a signal to the electronic control board 12. The electronic control board 12 controls the material pushing device 4 to work so that the material pushing device 4 pushes the solid detergent 5 on the material conveying channel 2 to the material discharging channel 3. When the material dropping detection device 6 does not detect the solid detergent 5 falling, the electronic control board 12 controls the material pushing device 4 to not work.

[0032] Circuit board 7 is provided with terminal 18, which is connected to control board 12 via wire.

[0033] A buckle 13 is provided on the opening of the mounting slot 9. The circuit board 7 is mounted on the mounting slot 9 by means of the buckle 13. The through hole 10 connects to the mounting slot 9 and plays a positioning role for the detection component 8.

[0034] The feeding body 1 is provided with a receiving part 14, which is located at the bottom of the conveying channel 2. The solid detergent 5 located at the bottom of the discharge channel 3 (i.e., the solid detergent 5 at the lowest end of the discharge channel 3) is placed on the receiving part 14. The pushing device 4 is provided with a pushing part 15, which is located at the position of the receiving part 14 when in the waiting state. The solid detergent 5 located at the bottom of the discharge channel 3 is placed on the pushing part 15. When the pushing part 15 moves in the first direction A, it pushes the solid detergent 5 located at the bottom of the discharge channel 3 into the discharge channel 3.

[0035] The feeding device 4 includes a motor 19, a crank 20, and a push rod 21. The motor 19 drives one end of the crank 20, and the other end of the crank 20 is connected to one end of the push rod 21. The feeding part 15 is located at the other end of the push rod 21. The motor 19 drives the crank 20 to rotate, and the crank 20 drives the push rod 21 to move laterally in a linear reciprocating motion. When the feeding device 4 feeds material, the push rod 21 drives the feeding part 15 to move in the first direction A. When the feeding device 4 resets, the push rod 21 drives the feeding part 15 to move in the opposite direction of the first direction A, so that the feeding part 15 returns to the waiting state.

[0036] It also includes a feeding port 16 located above the feeding body 1, a discharge port 17 located at the bottom of the feeding body 1, a conveying channel 2 connected to the feeding port 16, and a discharge channel 3 connected to the discharge port 17; a conveying passage 22 is located at the top of the feeding body 1, the upper end of the conveying passage 22 is connected to the feeding port 16, and the lower end of the conveying passage 22 is connected to the feeding body 1. The feeding port 16, the conveying passage 22, and the conveying channel 2 are connected in sequence. After the solid detergent 5 is put into the feeder through the feeding port 16, the solid detergent 5 is stored on the conveying passage 22 and the conveying channel 2, and the solid detergent 5 is arranged vertically; the bottom of the pushing part 15 is hollowed out. When the pushing part 15 pushes the solid detergent 5 located at the bottom of the conveying channel 2 to the discharge channel 3, the solid detergent 5 will fall downwards. The solid detergent 5 falls through the discharge channel 3 to the discharge port 17 and then into the inner drum of the dishwasher.

[0037] The feeding body 1 includes a first shell 23 and a second shell 24 that cover each other. A material conveying channel 2 and a material discharge channel 3 are formed between the first shell 23 and the second shell 24. An installation groove 9 is provided on the first shell 23. An inner cavity is formed between the first shell 23 and the second shell 24. A pushing device 4 and an electric control board 12 are provided on the inner cavity.

[0038] The feeding unit 1 is installed on the door 25 of the dishwasher.
