[0002] In some dishwashers on the market, a feeder is provided on the door body for putting solid detergent into the inner container. The upper and lower ends of the feeder are respectively provided with a feeding port and a discharging port. Users can put solid detergent into the interior of the feeder through the feeding port. The feeder is provided with a storage channel for storing solid detergent and a discharging device. When the discharging device works, it can push the solid detergent on the storage channel to the discharging channel, and then the solid detergent falls to the discharging port and falls into the inner container of the dishwasher through the discharging port. However, moisture in the inner container of the dishwasher may flow back to the discharging channel and reach the solid detergent on the storage channel, which is likely to cause the solid detergent to dissolve.

[0003] Therefore, it is necessary to make further improvements. Summary of the Invention

[0004] The purpose of the present invention is to provide a discharging device for a solid detergent feeder of a dishwasher, which has a simple structure, low cost, can prevent moisture from flowing back, is convenient to use, and has strong practicability, so as to overcome the deficiencies of the prior art.

[0005] A discharging device for a solid detergent feeder of a dishwasher designed according to this purpose is characterized in that: it includes a conveying channel and a discharging channel. A pushing member is movably arranged on the conveying channel, and a switch door member is movably arranged on the discharging channel. The pushing member and the switch door member are interconnected through a synchronization mechanism. When the pushing member moves in the first direction, it pushes the solid detergent on the conveying channel to the discharging channel. When the switch door member moves in the second direction, it opens the discharging channel. When the pushing member moves in the second direction for resetting, the switch door member moves in the first direction and closes the discharging channel.

[0006] The synchronization mechanism includes a synchronization wheel. The synchronization wheel is arranged between the pushing member and the switch door member, and the synchronization wheel is respectively engaged with the pushing member and the switch door member. When the pushing member moves in the first direction, it drives the switch door member to move in the second direction through the synchronization wheel. When the pushing member moves in the second direction, it drives the switch door member to move in the first direction through the synchronization wheel.

[0007] The synchronization wheel is a gear. A first rack is arranged on the pushing member, and a second rack is arranged on the switch door member. The gear is respectively meshed with the first rack and the second rack.

[0008] The synchronization mechanism further includes a motor and a transmission component. The motor is drivingly connected to the transmission component, and the transmission component is cooperatively connected to the material pushing component or the door opening / closing component. The motor drives the material pushing component or the door opening / closing component to move in the first direction and the second direction respectively through the transmission component.

[0009] One end of the material pushing component is provided with a notch for accommodating the solid detergent. The bottom of the notch is hollowed out, and a pushing portion is provided on one side of the notch. When the push rod moves in the first direction, the pushing portion pushes the solid detergent in the notch onto the discharge channel.

[0010] A placing portion is provided below the conveying channel, and a supporting portion is provided on the material pushing component. The solid detergent located at the bottom of the conveying channel is placed on the placing portion and within the notch. After the material pushing component moves in the first direction, the solid detergent located at the bottom of the conveying channel is placed on the supporting portion.

[0011] One end of the door opening / closing component is provided with a closing portion. When the door opening / closing component moves in the first direction, the closing portion moves onto the discharge channel to close the discharge channel. When the door opening / closing component moves in the second direction, the closing portion leaves the discharge channel to open the discharge channel.

[0012] It further includes a first sliding groove and a second sliding groove. The first rack is slidably arranged on the first sliding groove, and the second rack is slidably arranged on the second sliding groove.

[0013] The transmission component is a connecting rod. The motor is drivingly connected to one end of the connecting rod, and the other end of the connecting rod is cooperatively connected to the other end of the material pushing component. The motor drives the connecting rod to rotate, and the connecting rod drives the material pushing component to move in the first direction and the second direction respectively.

[0014] A sliding shaft is provided at the other end of the connecting rod, and a sliding groove is provided at the other end of the material pushing component. The sliding shaft is located on the sliding groove. When the connecting rod rotates, it drives the material pushing component to move in the first direction and the second direction respectively through the cooperation of the sliding shaft and the sliding groove.

[0025] The present invention will be further described below in conjunction with the drawings and embodiments.

[0026] See Figures 1-9, The discharging device of the solid detergent feeder of this dishwasher includes a conveying channel 1 and a discharging channel 2. There is solid detergent 5 stored on the conveying channel 1. A pushing component 3 is movably arranged back and forth on the conveying channel 1. A switch door component 4 is movably arranged back and forth on the discharging channel 2. The pushing component 3 and the switch door component 4 are interconnected through a synchronization mechanism; when the pushing component 3 moves in the first direction A (i.e., forward), it pushes the solid detergent 5 on the conveying channel 1 to the discharging channel 2, and the switch door component 4 moves in the second direction B (i.e., backward) and opens the discharging channel 2; when the pushing component 3 moves back in the second direction B, the switch door component 4 moves in the first direction A and closes the discharging channel 2; after the pushing component 3 moves back in the second direction B, it returns to a pending state (such as Figure 1 and Figure 3 shown), to prepare for the next pushing; the pushing component 3 is a push rod.

[0027] The synchronization mechanism includes a synchronous pulley 6. The synchronous pulley 6 is arranged between the pushing component 3 and the switch door component 4, and the synchronous pulley 6 is respectively engaged with the pushing component 3 and the switch door component 4; when the pushing component 3 moves in the first direction A, it drives the switch door component 4 to move in the second direction B through the synchronous pulley 6, and when the pushing component 3 moves in the second direction B, it drives the switch door component 4 to move in the first direction A through the synchronous pulley 6.

[0028] The synchronous pulley 6 is a gear. A first rack 7 is integrally arranged on the pushing component 3, and a second rack 8 is integrally arranged at the other end of the switch door component 4. The gear is respectively meshed with the first rack 7 and the second rack 8.

[0029] The synchronization mechanism further includes a motor 9 and a transmission component. The motor 9 is drivingly connected to the transmission component. The transmission component is cooperatively connected with the pushing component 3 or the switch door component 4. The motor 9 drives the pushing component 3 or the switch door 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 cooperatively connected 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] One end of the pushing component 3 is provided with a notch 10 for accommodating the solid detergent 5. The bottom of the notch 10 is hollowed out. A pushing part 11 is arranged on one side of the notch 10; when the push rod 4 moves in the first direction A, the pushing part 11 pushes the solid detergent 5 in the notch 10 to the discharging channel 2. Due to the hollow design at the bottom of the notch 10, the solid detergent 5 will fall down on the discharging channel 2.

[0031] A limiting part 14 is arranged 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 running out of position when the pushing part 11 pushes the solid detergent 5.

[0032] There is a placing part 12 provided below the conveying channel 1, and a supporting part 13 is provided on the pushing component 3. The solid detergents 5 are 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 lowermost end of the conveying channel 1) is placed on the placing part 12 and is located within the notch 12. After the pushing component 3 moves in the first direction A, the solid detergent 5 at the bottom of the conveying channel 1 is placed on the supporting part 13. That is, after the pushing component 3 pushes one solid detergent 5 at the bottom of the conveying channel 1 into the discharge channel 2, the other solid detergents 5 in the conveying channel 1 will fall. At this time, the solid detergent 5 at the bottom of the conveying channel 1 will be placed on the supporting part 13. When the pushing component 3 moves in the second direction B for reset, the solid detergent 5 at the bottom of the conveying channel 1 will fall into the notch 10 and be placed on the placing part 12, and at the same time, the other solid detergents 5 in the conveying channel 1 will also fall accordingly.

[0033] One end of the switch door component 4 is provided with a closing part 15. When the switch door 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 switch door 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 further includes a first sliding groove 16 and a second sliding groove 17. The first rack 7 is slidably arranged on the first sliding groove 16, and the second rack 8 is slidably arranged on the second sliding groove 17.

[0035] The transmission component is a connecting rod 18. One end of the connecting rod 18 is drivingly connected to the motor 9, and the other end of the connecting rod 18 is cooperatively 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] The other end of the connecting rod 18 is provided with a sliding shaft 19, and the other end of the pushing component 3 is provided with a sliding groove 20. The sliding shaft 19 is located on the sliding groove 20. When the connecting rod 18 rotates, it drives the pushing component 3 to move in the first direction A and the second direction B respectively through the cooperation of the sliding shaft 19 and the sliding groove 20. And when the pushing component 3 moves in the first direction A and the second direction B respectively, the sliding shaft 19 reciprocates 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. As Figure 4 shown, after the pushing component 3 moves to the maximum position in the first direction A, when the motor 9 drives the connecting rod 18 to rotate half a turn again (the rotation direction is the same as or opposite to the previous time), the connecting rod 18 drives the pushing component 3 to move in the second direction B for reset, and the pushing component 3 resets to the to-be-determined position. As Figure 3 shown.

[0037] The other end of the pusher component 3 is provided with a clearance groove 21 for clearance of the connecting rod 18. The sliding groove 20 is located outside the clearance groove 21. When the pusher component 3 is in the undetermined position, the connecting rod 18 is located within the clearance groove 21. When the pusher 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 discharging device more compact.

[0038] The motor 9 is a unidirectional motor or a forward and reverse motor. When the motor 9 is a unidirectional motor, the motor 9 drives the connecting rod 18 to perform a 360-degree cyclic rotation (which can be a 360-degree forward cyclic rotation or a 360-degree reverse cyclic rotation), thereby driving the pusher component 3 to reciprocate back and forth. When the motor 9 is a forward and reverse motor, the motor 9 drives the connecting rod 18 to perform a 180-degree reciprocating rotation (which can be a 180-degree forward reciprocating rotation or a 180-degree reverse reciprocating rotation), thereby driving the pusher component 3 to reciprocate back and forth.

[0039] The discharging device further includes a first housing 22 and a second housing 23 that are mutually covered. The first housing 22 and the second housing 23 form a feeding main body 24. A conveying channel 1 and a discharging channel 2 are formed between the first housing 23 and the second housing 24.

[0040] A microswitch 25 is provided inside the feeding main body 24, and a pressing portion 26 is provided on the pusher component 3. When the pusher component 3 is in the undetermined position, the pressing portion 26 acts on the microswitch 25. When the pusher component 3 moves in the first direction A, the pressing portion 26 disengages from the microswitch 25. When the pusher component 3 resets to the undetermined position, the pressing portion 26 acts on the microswitch 25 again to complete a cycle.

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

[0042] A triggering portion 28 is provided on the microswitch 25. When the pusher component 3 is in the undetermined position, the pressing portion 26 acts on the triggering portion 28.

[0043] A guiding groove 29 is provided on the first housing 22. The pusher component 3 is slidably arranged back and forth on the guiding groove 29, and the guiding groove 29 restricts the pusher component 3 to only reciprocate back and forth.

[0044] The feeder further includes a feeding port 30 provided above the feeding main body 24. A discharge port 31 is provided at the bottom of the feeding main body 24. A conveying passage 32 is provided at the top of the feeding main body 24. The upper end of the conveying passage 32 is connected to the feeding port 30, and the lower end of the conveying passage 32 is connected to the feeding main body 24. The feeding port 30, the conveying passage 32, and the conveying channel 1 are communicated in sequence. The discharge channel 2 is communicated with the discharge port 31. After the solid detergent 5 is put into the feeder through the feeding port 30, the solid detergent 5 is stored on the conveying passage 32 and the material conveying channel 2, and the solid detergents 5 are arranged vertically. When the pushing member 3 pushes the solid detergent 5 at the bottom of the conveying channel 1 to the discharge channel 2, the solid detergent 5 will fall downward. The solid detergent 5 falls through the discharge channel 2 to the discharge port 31 and falls into the inner cavity of the dishwasher through the discharge port 31.

[0045] The first sliding groove 16 and the second sliding groove 17 are provided on the first housing 22. An inner cavity is formed between the first housing 22 and the second housing 23. The motor 9, the pushing member 3, the door opening / closing member 4, the connecting rod 18, the synchronous pulley 6, and the control board 27 are arranged in the inner cavity. The synchronous pulley 6 is rotatably installed on the first housing 22.

[0046] The feeding main body 24 is installed on the door body 33 of the dishwasher.
