Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a novel solid detergent dispenser for dishwashers. Background Technology

[0002] Dishwashers are increasingly widely used due to their advantages such as good cleaning effect, food disinfection, and time and labor saving. Dishwashers require detergent, which can be solid or liquid. For dishwashers using solid detergent, a feeder is typically used. The feeder has a feed inlet and an outlet at its top and bottom, respectively. Inside the feeder is a conveying channel for transporting solid detergent, connected to the feed inlet. A pushing device is installed on the conveying channel to store and transport the solid detergent. When the pushing device is working, it pushes the solid detergent on the conveying channel above the outlet, where it falls into the dishwasher's inner tub. However, this feeder is inconvenient for users to operate, and the reliability of the feeder is generally low. Furthermore, because the outlet is connected to the inner tub, moisture from the inner tub can enter the feeder through the outlet, and the solid detergent on the conveying channel is constantly exposed to a humid environment, making it prone to dissolving.

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

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] See Figures 1-22 This novel dishwasher solid detergent dispenser includes a dispensing port 2, a dispensing body 3, and a dispensing port 4, all mounted on the door 1. The dispensing body 3 has a conveying channel 5 and a dispensing channel 6. The dispensing port 2 is connected to the conveying channel 5, and the dispensing channel 6 is connected to the dispensing port 4. A pushing device is mounted on the conveying channel 5, and a door opening / closing device is mounted on the dispensing channel 6. The pushing device and the door opening / closing device are linked together. When the pushing device pushes the solid detergent a from the conveying channel 5 to the dispensing channel 6, the door opening / closing device opens the dispensing channel 6. When the pushing device resets, the door opening / closing device closes the dispensing channel 6. This structure achieves automatic opening and closing of the dispensing process through mechanical linkage, improving reliability and user experience. By replacing independent drive with physical linkage, energy consumption and structural complexity can be reduced.

[0046] The feeding device includes a motor 7, a crank 8, and a push rod 9. The motor 7 drives one end of the crank 8, and the other end of the crank 8 is 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 laterally back and forth. When the crank 8 drives the push rod 9 to move laterally in the first direction A (i.e., forward), the push rod 9 pushes the solid detergent a on the conveying channel 5 laterally onto the discharge channel 6 (e.g., ...). Figure 2 and Figure 4 As shown), when crank 8 drives push rod 9 to move laterally in the second direction B (i.e., backward), push rod 9 returns to the predetermined position (e.g., ...). Figure 1 and Figure 3 (as shown in the figure). The above structure uses crank 8 as a transmission component. It has a simple structure and few parts, which simplifies the transmission structure and can greatly reduce manufacturing costs.

[0047] The door opening and closing device includes a door opening and closing component 10. A synchronous wheel 11 is provided between the push rod 9 and the door opening and closing component 10. The synchronous wheel 11 is engaged with the push rod 9 and the door opening and closing component 10 respectively. When the push rod 9 moves laterally in the first direction A, it drives the door opening and closing component 10 to move laterally in the second direction B through the synchronous wheel 11, so that the door opening and closing component 10 opens the discharge channel 6. When the push rod 9 moves laterally in the second direction B to reset, it drives the door opening and closing component 10 to move laterally in the first direction A through the synchronous wheel 11, so that the door opening and closing component 10 closes the discharge channel 6.

[0048] The synchronous pulley 6 is a gear, the push rod 9 is integrally provided with a first rack 46, and the door opening and closing component 10 is integrally provided with a second rack 47 at one end. The gear meshes with the first rack 46 and the second rack 47 respectively.

[0049] The other end of the door opening and closing component 4 is provided with a closing part 48; when the door opening and closing component 10 moves in the first direction A, the closing part 48 moves to the discharge channel 6 to close the discharge channel 6; when the door opening and closing component 10 moves in the second direction B, the closing part 48 leaves the discharge channel 6 to open the discharge channel 6.

[0050] The door opening and closing device also includes a seal 49, which is fitted onto the closing part 48. When the closing part 48 moves to the discharge channel 6, the seal 49 seals the gap between the closing part 48 and the feeding body 3, thereby completely preventing moisture from the inner tub of the dishwasher from entering the feeder through the discharge port 4.

[0051] A sliding shaft 50 is provided at the other end of the crank 8, and a sliding groove 51 is provided at one end of the push rod 9. The sliding shaft 50 is located on the sliding groove 51. When the crank 8 rotates, the push rod 9 is driven to reciprocate laterally through the cooperation of the sliding shaft 50 and the sliding groove 51. When the push rod 9 reciprocates laterally, the sliding shaft 50 slides back and forth 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 laterally in the first direction A to the maximum position. Figure 4 As shown, after push rod 9 moves laterally to its maximum position in the first direction A, when motor 7 drives crank 8 to rotate half a turn again (in the same or opposite direction as before), crank 8 drives push rod 9 to move laterally in the second direction B, and push rod 9 returns to its predetermined position. Figure 3 As shown.

[0052] The feeding channel 5 and / or the discharging channel 6 are equipped with a material dropping detection device for detecting the falling of solid detergent a. The feeding body 3 is equipped with a control board 12, which is electrically connected to the material dropping detection device and the motor 7. When the solid detergent a on the feeding channel 5 is used up and the material dropping detection device does not detect the falling of solid detergent a, the control board 12 will control the motor 7 to stop working, so as to avoid the motor 7 running idle and consuming energy, and improve the energy efficiency of the dishwasher.

[0053] The control board 12 is equipped with a micro switch 13, and the push rod 9 is equipped with a pressing part 14. When the push rod 9 is in the waiting position, the pressing part 14 acts on the micro switch 13. When the push rod 9 moves laterally in the first direction A, the pressing part 14 disengages from the micro switch 13. When the push rod 9 returns to the waiting position, the pressing part 14 acts on the micro switch 13 again to complete one cycle.

[0054] The control board 12 is electrically connected to the motor 7 and the micro switch 13 respectively. When the pressing part 14 acts on the micro switch 13 again, the control board 12 controls the motor 7 to stop working.

[0055] The micro switch 13 is provided with a trigger part 52. When the push rod 9 is in the waiting position, the pressing part 14 acts on the trigger part 52.

[0056] The other end of the push rod 9 is provided with a positioning notch 53 for accommodating solid detergent a. The bottom of the positioning notch 53 is hollowed out, and a pushing part 54 is provided on one side of the positioning notch 53. When the push rod 9 moves laterally in the first direction A, the pushing part 54 pushes the solid detergent a in the positioning notch 53 laterally onto the discharge channel 6. Due to the hollowed-out design at the bottom of the positioning notch 53, the solid detergent a will fall down on the discharge channel 6 and fall into the discharge port 4.

[0057] A second limiting part 55 is provided on the other side of the positioning notch 53. The solid detergent a inside 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 moving when the pushing part 54 pushes the solid detergent a.

[0058] The feeding body 3 is provided with a receiving part 56, which is located at the bottom of the conveying channel 5. The push rod 9 is provided with a support part 57. The solid detergent a is arranged vertically on the conveying channel 5. When the push rod 9 is in the waiting position, the solid detergent a at the bottom of the conveying channel 5 (i.e., the solid detergent a at the lowest end of the conveying channel 5) is placed on the receiving part 56 and located in the positioning notch 53. After the push rod 9 moves laterally in the first direction A, the solid detergent a at the bottom of the conveying channel 5 is placed on the receiving part 56. On the support 57, after the push rod 9 pushes one solid detergent a at the bottom of the conveying channel 5 to the discharge channel 6, the other solid detergents a in the conveying channel 5 will fall down. At this time, the solid detergent a at the bottom of the conveying channel 5 will be placed on the support 57. When the push rod 9 returns to the waiting position, the solid detergent a at the bottom of the conveying channel 5 will fall into the positioning notch 53 and be placed on the receiving part 56. At the same time, the other solid detergents a in the conveying channel 5 will also fall down.

[0059] The feeding body 3 is provided with a guide groove 58. The push rod 9 is slidably mounted on the guide groove 58, and the guide groove 58 restricts the push rod 9 to only move laterally back and forth.

[0060] Motor 7 is a unidirectional motor or a forward and reverse reversible motor. When motor 7 is a unidirectional motor, motor 7 will drive crank 8 to rotate 360 ​​degrees in a cyclic rotation (either 360 degrees in a forward rotation or 360 degrees in a reverse rotation), thereby driving push rod 9 to move laterally back and forth. When motor 7 is a forward and reverse reversible motor, motor 7 will drive crank 8 to rotate 180 degrees in a reversible rotation (either 180 degrees in a forward rotation or 180 degrees in a reverse rotation), thereby driving push rod 9 to move laterally back and forth.

[0061] When the material drop detection device is set in the conveying channel 5, it is located at the height of the second to last solid detergent a at the bottom of the conveying channel 5. When there is only one solid detergent a left in the conveying channel 5, the material drop detection device does not detect the solid detergent a falling. Then the pushing device will push the remaining solid detergent a to the discharge channel 6 to ensure that after the material drop detection device does not detect the solid detergent a falling, the pushing device can push the solid detergent a once more, that is, the dishwasher can use solid detergent a once more.

[0062] The material dropping detection device (i.e., the first material dropping detection device 39, the second material dropping detection device 40, the third material dropping detection device 99 and the fourth material dropping detection device 101) includes a circuit board 59 and a detection component 60. The material conveying channel 5 and the material discharging channel 6 are respectively provided with mounting grooves 61 on both sides. The circuit board 59 is limited and installed on the mounting groove 61 by a buckle 62, and the detection component 60 is installed on the circuit board 59.

[0063] Through holes 63 are provided on both sides of the material conveying channel 5 and the material discharging channel 6. The material conveying channel 5 is connected to the corresponding through hole 63, and the material discharging channel 6 is connected to the corresponding through hole 63. The detection component 60 is provided with a detection part 64 for detecting the falling solid detergent a. The detection part 64 is located on the through hole 63. This structure ensures that the falling detection device can accurately detect the falling solid detergent a. The detection part 64 is a detection head. The through hole 63 plays a positioning role for the detection component 60.

[0064] The material feeding detection device is a light sensor, such as an infrared light sensor.

[0065] The control board 12 is electrically connected to the circuit board 59. When the material dropping detection device detects the solid detergent a falling, it sends a signal to the control board 12. The control board 12 controls the motor 7 to work so that the pushing device pushes the solid detergent a on the conveying channel 5 to the discharge channel 6. When the material dropping detection device does not detect the solid detergent a falling, the control board 12 controls the motor 7 not to work.

[0066] Circuit board 59 is provided with terminal 65, which is connected to control board 12 via wire.

[0067] 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 to the door body 1. The bottom cover 16 is provided with a feeding through hole 17 that connects to the feeding channel 5. When the face cover 15 rotates, the feeding through hole 17 is opened or closed, 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 to prevent moisture on the inner tub of the dishwasher from entering the feeder through the feeding port 2. After solid detergent a is put into the feeder through the feeding port 2, the solid detergent a is stored on the conveying passage 26 and the feeding channel 5, and the solid detergent a is arranged vertically.

The discharge port 4 is provided with a guide arc surface 71 for guiding the solid detergent a into the receiving groove 23. The guide arc surface 71 is provided on the second housing 83. When the dishwasher sprays water onto the shelf 22, the solid detergent a on the shelf 22 will dissolve. The dissolved solid detergent a falls into the inner tub through the perforated hole 24. Since the position of the rack 22 is not blocked by the tableware, the water sprayed by the dishwasher's spray arm can reach the rack 22. The rack 22 is designed so that the solid detergent a does not fall into the inner tub after it comes out of the discharge port 4, but reaches the rack 22. The water sprayed by the spray arm can reach the rack 22 so that the solid detergent a on the rack 22 can be dissolved. Combined with the perforated design of the rack 22, the dissolved solid detergent a can fall into the inner tub, thereby improving the washing effect of the tableware.

[0078] A blower 31 is installed at the upper end of the discharge channel 6, and the discharge port 4 is located at the lower end of the discharge channel 6. The air outlet 32 ​​of the blower 31, the discharge channel 6 and the discharge port 4 are connected in sequence. The air outlet 32 ​​of the blower 31 is directly facing the discharge channel 6 and the discharge port 4. The air outlet 32 ​​of the blower 31 generates air that blows towards the discharge channel 6 and reaches the discharge port 4. This blows the moisture on the discharge channel 6 out of the feeder through the discharge port 4, and the moisture returns to the inner tank. This achieves the effect of drying the discharge channel 6 and prevents the moisture on the discharge channel 6 from reaching the solid detergent a on the conveying channel 5 and causing the solid detergent a to dissolve.

[0079] The air outlet 32 ​​of the blower 31 is directly opposite the discharge channel 6 and the discharge port 4, so that the air generated by the air outlet 32 ​​of the blower 31 can blow directly into the discharge channel 6, thereby quickly expelling the moisture on the discharge channel 6 and improving the drying effect.

[0080] The side of the feeding body 3 is provided with an air inlet 33 that connects to the outside. The air inlet 34 of the blower 31 is connected to the air inlet 33.
