[0002] Dishwashers have the advantages of good cleaning effect, being able to disinfect tableware, saving time and effort, etc., so they are used more and more widely; when a dishwasher washes dishes, detergents are needed, and the detergents are solid detergents or liquid detergents. For dishwashers using solid detergents, generally a feeder is used for feeding. The upper and lower ends of the feeder are respectively provided with a feeding port and a discharging port. A conveying channel for conveying solid detergent is arranged inside the feeder. The conveying channel communicates with the feeding port. A pushing device is arranged on the conveying channel. The conveying channel is used for storing and conveying solid detergent. When the pushing device works, the solid detergent on the conveying channel can be pushed above the discharging port, and then the solid detergent falls to the discharging port and falls into the inner cavity of the dishwasher through the discharging port; the above-mentioned feeder is not convenient for users to operate, and the feeding reliability is average. At the same time, since the discharging port communicates with the inner cavity, the water vapor in the inner cavity will enter the inside of the feeder through the discharging port, and the solid detergent on the conveying channel is exposed to a humid environment for a long time, making the solid detergent prone to dissolution.

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

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] See Figures 1 - 22 , for this new type of dishwasher solid detergent feeder, which includes a feeding port 2, a feeding main body 3 and a discharging port 4 provided on the door body 1. A material conveying channel 5 and a discharging channel 6 are provided on the feeding main body 3. The feeding port 2 communicates with the material conveying channel 5, and the discharging channel 6 communicates with the discharging port 4. A pushing device is provided on the material conveying channel 5, and a door opening and closing device is provided on the discharging channel 6. The pushing device and the door opening and closing device are interlocked with each other; when the pushing device pushes the solid detergent a on the material conveying channel 5 to the discharging channel 3, it interlocks the door opening and closing device to open the discharging channel 3, and when the pushing device resets, it interlocks the door opening and closing device to close the discharging channel 3; the above structure realizes the automatic opening and closing of the feeding process through mechanical linkage, improves the reliability and user experience, and can reduce the energy consumption and structural complexity by replacing the independent drive with physical linkage.

[0040] The pushing device includes a motor 7, a crank 8 and a push rod 9. One end of the motor 7 is drivingly connected to one end of the crank 8, and the other end of the crank 8 is cooperatively connected to one end of the push rod 9; the motor 7 drives the crank 8 to rotate, and the crank 8 drives the push rod 9 to move horizontally back and forth. When the crank 8 drives the push rod 9 to move horizontally in the first direction A (i.e., forward), the push rod 9 horizontally pushes the solid detergent a on the material conveying channel 5 to the discharging channel 6 (as shown in Figure 2 and Figure 4 ), when the crank 8 drives the push rod 9 to move horizontally in the second direction B (i.e., backward), the push rod 9 resets to a pending position (as shown in Figure 1 and Figure 3 ); the above structure uses the crank 8 as a transmission component, has a simple structure and few components, simplifies the transmission structure, and can greatly reduce the manufacturing cost.

[0041] The door opening and closing device includes a door opening and closing component 10. A synchronous pulley 11 is provided between the push rod 9 and the door opening and closing component 10. The synchronous pulley 11 is respectively engaged with the push rod 9 and the door opening and closing component 10; when the push rod 9 moves horizontally in the first direction A, it drives the door opening and closing component 10 to move horizontally in the second direction B through the synchronous pulley 11, so that the door opening and closing component 10 opens the discharging channel 3. When the push rod 9 moves horizontally in the second direction B and resets, it drives the door opening and closing component 10 to move horizontally in the first direction A through the synchronous pulley 11, so that the door opening and closing component 10 closes the discharging channel 3.

[0042] The synchronous pulley 6 is a gear. A first rack 46 is integrally provided on the push rod 9, and a second rack 47 is integrally provided at one end of the door opening and closing component 10. The gear is respectively engaged with the first rack 46 and the second rack 47.

[0043] At the other end of the door opening and closing member 4, there is a closing portion 48; when the door opening and closing member 10 moves in the first direction A, the closing portion 48 moves to the discharge channel 6 to close the discharge channel 6; when the door opening and closing member 10 moves in the second direction B, the closing portion 48 leaves the discharge channel 6 to open the discharge channel 6.

[0044] The door opening and closing device further includes a seal 49 sleeved on the closing portion 48. When the closing portion 48 moves to the discharge channel 6, the seal 49 seals the gap between the closing portion 48 and the feeding main body 3, thereby completely preventing the water vapor in the dishwasher inner tank from entering the inside of the feeder through the discharge port 4.

[0045] At the other end of the crank 8, there is a sliding shaft 50, and at one end of the push rod 9, there is a sliding groove 51. The sliding shaft 50 is located on the sliding groove 51. When the crank 8 rotates, the push rod 9 is driven to move horizontally back and forth through the cooperation of the sliding shaft 50 and the sliding groove 51. And when the push rod 9 moves horizontally back and forth, the sliding shaft 50 reciprocally slides on the sliding groove 51; when the motor 7 drives the crank 8 to rotate half a turn, the crank 8 drives the push rod 9 to move horizontally to the maximum position in the first direction A. As Figure 4 shown, after the push rod 9 moves horizontally to the maximum position in the first direction A, when the motor 7 drives the crank 8 to rotate half a turn again (the rotation direction is the same as or opposite to the previous time), the crank 8 drives the push rod 9 to move horizontally in the second direction B, and the push rod 9 returns to the pending position, as Figure 3 shown.

[0046] On the feeding channel 5 and / or the discharge channel 6, there is a falling material detection device for detecting the falling of the solid detergent a. Inside the feeding main body 3, there is a control board 12, and the control board 12 is electrically connected to the falling material detection device and the motor 7 respectively; when the solid detergent a on the feeding channel 5 is used up and the falling material detection device does not detect the falling of the solid detergent a, the control board 12 will control the motor 7 to stop working, avoiding the idling energy consumption of the motor 7 and improving the energy efficiency of the dishwasher.

[0047] On the control board 12, there is a micro switch 13, and on the push rod 9, there is a pressing portion 14. When the push rod 9 is in the pending position, the pressing portion 14 acts on the micro switch 13. When the push rod 9 moves horizontally in the first direction A, the pressing portion 14 disengages from the micro switch 13. When the push rod 9 returns to the pending position, the pressing portion 14 acts on the micro switch 13 again to complete a cycle.

[0048] The control board 12 is electrically connected to the motor 7 and the micro switch 13 respectively. When the pressing portion 14 acts on the micro switch 13 again, the control board 12 controls the motor 7 to stop working.

[0049] On the micro switch 13, there is a triggering portion 52. When the push rod 9 is in the pending position, the pressing portion 14 acts on the triggering portion 52.

[0050] At the other end of the push rod 9, there is a positioning notch 53 for accommodating the solid detergent a. The bottom of the positioning notch 53 is hollowed out, and a pushing part 54 is arranged on one side of the positioning notch 53. When the push rod 9 moves horizontally in the first direction A, the pushing part 54 horizontally pushes the solid detergent a in the positioning notch 53 onto the discharge channel 6. Due to the hollow design at the bottom of the positioning notch 53, the solid detergent a will fall downward on the discharge channel 6 and then fall to the discharge port 4.

[0051] On the other side of the positioning notch 53, there is a second limiting part 55. The solid detergent a in the positioning notch 53 is limited between the pushing part 54 and the second limiting part 55, which can prevent the solid detergent a from shifting when the pushing part 54 pushes the solid detergent a.

[0052] On the feeding main body 3, there is a placing part 56, and the placing part 56 is located at the bottom of the feeding channel 5. On the push rod 9, there is a supporting part 57. The solid detergents a are arranged vertically on the feeding channel 5. When the push rod 9 is in the waiting position, the solid detergent a at the bottom of the feeding channel 5 (i.e., the solid detergent a at the lowermost end of the feeding channel 5) is placed on the placing part 56 and is located within the positioning notch 53. After the push rod 9 moves horizontally in the first direction A, the solid detergent a at the bottom of the feeding channel 5 is placed on the supporting part 57. That is, after the push rod 9 pushes one solid detergent a at the bottom of the feeding channel 5 to the discharge channel 6, the other solid detergents a in the feeding channel 5 will fall. At this time, the solid detergent a at the bottom of the feeding channel 5 will be placed on the supporting part 57. When the push rod 9 resets to the waiting position, the solid detergent a at the bottom of the feeding channel 5 will fall into the positioning notch 53 and be placed on the placing part 56, and at the same time, the other solid detergents a in the feeding channel 5 will also fall accordingly.

[0053] Inside the feeding main body 3, there is a guiding groove 58, and the push rod 9 is horizontally reciprocatingly slidably arranged on the guiding groove 58. The guiding groove 58 restricts the push rod 9 to only move horizontally in a reciprocating manner.

[0054] The motor 7 is a unidirectional motor or a forward and reverse motor. When the motor 7 is a unidirectional motor, the motor 7 will drive the crank 8 to rotate in a 360-degree cycle (it can be a 360-degree forward cycle rotation or a 360-degree reverse cycle rotation), thereby driving the push rod 9 to move horizontally in a reciprocating manner. When the motor 7 is a forward and reverse motor, the motor 7 will drive the crank 8 to rotate in a 180-degree reciprocating manner (it can be a 180-degree forward reciprocating rotation or a 180-degree reverse reciprocating rotation), thereby driving the push rod 9 to move horizontally in a reciprocating manner.

[0055] When the blanking detection device is arranged on the material conveying channel 5, the blanking detection device is located at the height position of the second-to-last solid detergent a at the bottom of the material conveying channel 5. When there is only one solid detergent a left on the material conveying channel 5, at this time, the blanking detection device does not detect the falling of the solid detergent a. After that, the pushing device will still push the remaining one solid detergent a to the discharging channel 6, ensuring that after the blanking detection device does not detect the falling of the solid detergent a, the pushing device can still push the solid detergent a once, that is, the dishwasher can still use the solid detergent a once.

[0056] The blanking detection device (i.e., the first blanking detection device 39, the second blanking detection device 40, the third blanking detection device 99, and the fourth blanking detection device 101) includes a circuit board 59 and a detection component 60. Installation grooves 61 are respectively arranged on both sides of the material conveying channel 5 and the discharging channel 6. The circuit board 59 is installed in the installation groove 61 by means of a buckle 62 in a limited way, and the detection component 60 is installed on the circuit board 59.

[0057] Through holes 63 are respectively arranged on both sides of the material conveying channel 5 and the discharging channel 6. The material conveying channel 5 is communicated with the corresponding through hole 63, and the discharging channel 6 is communicated with the corresponding through hole 63. A detection part 64 for detecting the falling of the solid detergent a is arranged on the detection component 60. The detection part 64 is arranged on the through hole 63. This structure ensures that the blanking detection device can accurately detect the falling of the solid detergent a; the detection part 64 is a detection head; the through hole 63 plays a positioning role for the detection component 60.

[0058] The blanking detection device is an optical sensor, such as an infrared optical sensor.

[0059] The control board 12 is electrically connected to the circuit board 59. When the blanking detection device detects the falling of the solid detergent a, it sends a signal to the control board 12, and the control board 12 controls the motor 7 to work so that the pushing device pushes the solid detergent a on the material conveying channel 5 to the discharging channel 6; when the blanking detection device does not detect the falling of the solid detergent a, the control board 12 controls the motor 7 not to work.

[0060] A wiring terminal 65 is arranged on the circuit board 59, and the wiring terminal 65 is connected to the control board 12 through an electric wire.

[0061] A cover assembly is provided on the feeding port 2. The cover assembly includes a face cover 15 and a bottom cover 16 that are rotatably connected to each other. The bottom cover 16 is fixed on the door body 1. A feeding through hole 17 communicating with the material conveying channel 5 is provided on the bottom cover 16. When the face cover 15 rotates, it opens or closes the feeding through hole 17, thereby opening or closing the feeding port 2. When the feeder is not in use, the feeding port 2 can be closed through the cover assembly, so as to prevent the water vapor on the inner liner of the dishwasher from entering the inside of the feeder through the feeding port 2. After the solid detergent a is put into the inside of the feeder through the feeding port 2, the solid detergent a is stored on the conveying aisle 26 and the material conveying channel 5, and the solid detergent a is arranged vertically.

[0062] A rotating shaft 66 is provided on one side of the face cover 15, and a rotating hole 67 is provided on one side of the bottom cover 16. The rotating shaft 66 is rotatably connected to the rotating hole 67. An elastic first buckle 68 is provided on the other side of the face cover 15, and an elastic buckling position 69 is provided on the other side of the bottom cover 16. When the face cover 15 closes the feeding through hole 17, the first buckle 68 and the elastic buckling position 69 are buckled with each other, so that the face cover 15 and the bottom cover 16 are buckled to each other. A handle 70 for rotating and operating the face cover 15 is also provided on the other side of the face cover 15.

[0063] An installation position 18 is provided on the door body 1, and the cover assembly is installed on the installation position 18. A first sealing gasket 19 is provided between the back surface of the bottom cover 16 and the installation position 18, and the first sealing gasket 19 is sleeved on the bottom cover 16. The first sealing gasket 19 can seal the gap between the bottom cover 16 and the door body 1.

[0064] A first sealing ring 20 is provided on the face cover 15 at a position corresponding to the feeding through hole 17. A sealing rib 21 protrudes from the front surface of the bottom cover 16. When the face cover 15 closes the feeding through hole 17, the sealing rib 21 abuts against the first sealing ring 20, and the first sealing ring 20 can seal the gap between the face cover 15 and the bottom cover 16.

[0065] A storage rack 22 protruding outside the door body 1 is provided at the discharge port 4. An accommodation groove 23 is provided on the storage rack 22. The accommodation groove 23 is used to receive the solid detergent a coming out of the discharge port 4. Hollow holes 24 are provided on the side and bottom of the storage rack 22. The discharge port 4, the accommodation groove 23 and the hollow holes 24 are communicated in sequence. A guiding arc surface 71 for guiding the solid detergent a into the accommodation groove 23 is provided at the discharge port 4. The guiding arc surface 71 is provided on the second housing 83. When the dishwasher spray arm sprays water on the storage rack 22, the solid detergent a on the storage rack 22 will dissolve. The dissolved solid detergent a falls into the inner container through the hollow holes 24. Since the position of the storage rack 22 will not be blocked by tableware, the water sprayed by the dishwasher spray arm can reach the storage rack 22. The setting of the storage rack 22 enables the solid detergent a not to fall into the inner container after coming out of the discharge port 4, but to reach the storage rack 22. The water sprayed by the spray arm can reach the storage rack 22, so that the solid detergent a on the storage rack 22 can dissolve. Combined with the hollow design of the storage rack 22, the dissolved solid detergent a can fall into the inner container, thereby improving the washing effect of the tableware.

[0066] It further includes a conveying aisle 26 provided on the door body 1. The conveying channel 26 adapts to the shape and layout of the door body 1. The feeding port 2, the conveying aisle 26 and the feeding channel 5 are communicated in sequence. The solid detergents a are arranged vertically on the conveying aisle 26 and the feeding channel 3. The conveying aisle 26 and the feeding channel 3 are used to store the solid detergents a. A rib 27 is provided on the back of the bottom cover 16. A first groove 28 is provided at the upper end of the conveying aisle 26. The rib 27 and the first groove 28 are inserted into each other. A plugging part 29 is provided at the lower end of the conveying aisle 26. A plugging port 30 is provided at the upper end of the feeding main body 3. The plugging part 29 and the plugging port 30 are inserted into each other. One end of the conveying aisle 26 is connected to the feeding port 2, and the other end is connected to the upper end of the feeding main body 3. The conveying aisle 26 adapts to the shape and layout of the door body 1, so that different models of dishwashers can simply open conveying channels with different shapes and specifications without changing the structural shapes of the feeding port and the feeding main body, improving the adaptability and applicability of the solid detergent feeder.

[0067] The bottom cover 9, the first gasket 19 and the conveying aisle 26 are connected together by screws and fixed on the door body 1 together.

[0068] The conveying passage 26 includes a first cover body 72 and a second cover body 73 that cover each other.
