Description

Technical Field

[0001] The invention belongs to the technical field of household kitchen and bathroom appliances, in particular to the technical field of dishwashers, and specifically relates to a powdered detergent dispensing device. Background Art

[0002] Dishwashers are now widely used in people's lives to replace the cumbersome manual dishwashing process. Dishwashers need to be used with detergents to ensure the cleaning effect. Detergents are mostly liquid or powdered. The detergent dispensing devices of dishwashers on the market are mainly for liquid detergents. Powdered detergents have poor fluidity, are susceptible to moisture, are easy to agglomerate, and are difficult to quantify. They have higher requirements for automatic dispensing devices. The powdered detergent dispensing devices in the prior art all achieve the dispensing of detergents by controlling the opening and closing of the storage cavity. The detergent is directly put into the washing cavity from the storage cavity. Therefore, the detergent loaded in the storage cavity can only be dispensed once, and multiple dispensing cannot be achieved. The dispensing efficiency is low, and quantitative dispensing cannot be achieved. Excessive detergent will cause waste, and insufficient detergent will cause poor cleaning effect. At the same time, after the powdered detergent is damp and agglomerated, it will cause the dispensing device to fail to dispense normally. Summary of the invention

[0003] The present invention aims to solve the problems of low dispensing efficiency and dispensing accuracy and poor dispensing reliability of powdered detergent dispensing devices in the prior art, and provides a powdered detergent dispensing device. The invention objective of the present invention is achieved through the following technical solutions:

[0004] A powder detergent dispensing device comprises a temporary storage device and a driving assembly for driving the temporary storage device to rotate, wherein at least two temporary storage chambers are arranged inside the temporary storage device, and the temporary storage chambers are evenly distributed around the central axis of the temporary storage device, the feed openings of the temporary storage chambers are all arranged on the upper end surface of the temporary storage device, and the discharge openings of the temporary storage chambers are all arranged through the lower end surface of the temporary storage device; a storage chamber with a feed opening is arranged above the temporary storage device, and a sealing assembly with a feeding opening is arranged below the temporary storage device. The temporary storage device is driven by the driving assembly to intermittently rotate with its own central axis as the rotation axis, the feed openings of the temporary storage chambers are successively reached to the bottom of the storage chamber feeding opening to load detergent, and the discharge openings of the temporary storage chambers are successively reached to the top of the feeding opening to dispense detergent, and when the feed opening of one temporary storage chamber reaches the bottom of the storage chamber feeding opening, the discharge opening of the other temporary storage chamber reaches the top of the feeding opening. The temporary storage chamber rotates under the drive of the driving component, and multiple temporary storage chambers rotate around the central axis of the temporary storage chamber. When one of them reaches below the feeding port, the other reaches above the feeding port. At this time, the temporary storage chamber stops rotating, and the two temporary storage chambers can be filled and put in detergent at the same time, which improves the putting efficiency and reduces the waiting time. By controlling the pause time of the temporary storage chamber and the volume of the temporary storage chamber, the quantitative loading and quantitative putting of the temporary storage chamber can be controlled, and the temporary storage chamber can realize multiple loading and multiple putting, which further improves the putting efficiency.

[0005] Preferably, a feeding tube extending toward the upper end face of the temporary storage is formed below the feeding port, and an upper sealing ring abutting against the upper end face of the temporary storage is mounted on the lower end of the feeding tube, and a first pressing spring for pressing the upper sealing ring down to the upper end face of the temporary storage is also mounted on the feeding tube. By providing the first pressing spring and the upper sealing ring, leakage of the temporary storage chamber during the process of filling detergent can be avoided, and the upper sealing ring can also scrape out excess detergent in the temporary storage chamber and allow it to enter the next temporary storage chamber, ensuring that the loading amount of each temporary storage chamber is consistent, so as to achieve quantitative feeding.

[0006] Preferably, the volumes of the temporary storage chambers are the same, and the areas of the feed port and the discharge port of each temporary storage chamber are the same. The above arrangement can ensure that the feed and discharge amounts of the two temporary storage chambers in the same group are consistent within the same time, thereby achieving quantitative delivery.

[0007] Preferably, a rolling assembly is arranged just above the feeding port, and the rolling assembly includes a first rolling wheel and a second rolling wheel arranged adjacent to each other, and the two rolling wheels are respectively arranged in the storage chamber through the first transmission shaft and the second transmission shaft, and the two rolling wheels rotate in opposite directions under the drive of the driving assembly to roll the detergent passing through. The rolling assembly is arranged just above the feeding port, and can roll and crush the detergent to be entered into the temporary storage chamber, so as to prevent the agglomerated detergent from entering the temporary storage chamber and affecting the normal delivery of the device, and the detergent enters the temporary storage chamber in powder form, which can improve the delivery accuracy.

[0008] Preferably, the first transmission shaft and the second transmission shaft are arranged perpendicular to the direction of the detergent dropping, and the first rolling wheel and the second rolling wheel cover the entire detergent dropping path.

Using one power source to drive the temporary storage device and the rolling wheel at the same time is energy-saving and easy to control, and can simplify the overall structure of the device and reduce manufacturing costs.

[0010] Preferably, the second driving gear and the second passive gear are both bevel gears, the axis intersection angle of the two bevel gears is 90 degrees, the second passive gear is fixed to the end of the first transmission shaft, and the first transmission shaft is also coaxially fixed with a third passive gear, and the third passive gear is meshed with a fourth passive gear fixed on the second transmission shaft. By setting two bevel gears, the transmission direction is changed, the structure is simple, and the transmission is reliable, so that the rotation axis of the rolling wheel is perpendicular to the rotation axis of the temporary storage, ensuring that the detergent is fully rolled.

[0011] Preferably, the sealing assembly comprises a sealing plate, which is arranged perpendicular to the central axis of the temporary storage device and covers the discharge ports of all temporary storage chambers, and the feeding port is opened on the sealing plate.

[0012] Preferably, the discharge port of the temporary storage chamber is opened out of the lower end surface of the temporary storage device, and an annular convex edge is formed at each discharge port. The sealing assembly also includes a gasket located between the temporary storage device and the sealing plate. The gasket is formed with lower sealing rings that are the same in number as the annular convex edges. A lower sealing ring is mounted on each annular convex edge. The gasket rotates with the temporary storage device, and a second downward pressure spring is also provided between the lower end surface of the temporary storage device and the gasket to press the gasket toward the sealing plate. The setting of the sealing assembly can effectively solve the problem that detergent will leak out of the discharge port of the temporary storage chamber during the rotation of the temporary storage device, and ensure that all detergents in the temporary storage chamber can reach the top of the feeding port and be thrown out from the feeding port to achieve accurate feeding.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] This embodiment discloses a powder detergent dispensing device, which is applied to a dishwasher and is used to dispense powder detergent.

[0030] See also Figure 1-10 The powder detergent dispensing device includes a temporary storage device 10 and a driving assembly for driving the temporary storage device 10. The temporary storage device 10 is a truncated cone with a small top and a large bottom. Four temporary storage chambers are provided in the temporary storage device 10. All of them are cylindrical, namely, a first temporary storage chamber 11, a second temporary storage chamber 12, a third temporary storage chamber 13, and a fourth temporary storage chamber 14. The four temporary storage chambers are evenly distributed around the central axis of the temporary storage device 10 and are obliquely provided in the temporary storage device 10. The circular feed openings of the four temporary storage chambers 15 are all opened on the upper end surface of the temporary storage chamber 10, and the feed openings 15 of the two temporary storage chambers have diameters located on the same straight line, and the straight line passes through the central axis of the temporary storage chamber 10. The circular discharge openings 16 of the four temporary storage chambers are all protruded from the lower end surface of the temporary storage chamber 10, and an annular convex edge 161 is formed at each discharge opening 16. The discharge openings 16 of the two temporary storage chambers in the same group have diameters located on the same straight line, and the straight line passes through the central axis of the temporary storage chamber 10.

[0031] A storage chamber 20 with a feeding port 21 is provided above the temporary storage 10, and a sealing component with a feeding port 52 is provided below the temporary storage 10. Driven by the driving component, the temporary storage 10 intermittently rotates with its own central axis as the rotation axis, and the four temporary storage chambers rotate around the central axis of the temporary storage 10. When one of the two temporary storage chambers arranged oppositely reaches below the feeding port 21 and its feed port 15 is aligned with the feeding port 21, the other reaches above the feeding port 52 and its discharge port 16 is aligned with the feeding port 52, the temporary storage 10 pauses its rotation at this time, and the two temporary storage chambers can be respectively filled and dispensed with detergent at the same time, so as to improve the dispensing efficiency and reduce the waiting time. By controlling the pause time of the temporary storage 10 and the volume of the temporary storage chamber, the quantitative loading and quantitative dispensing of the temporary storage chamber can be controlled, and the temporary storage 10 can achieve multiple dispensing in one movement cycle, further improving the dispensing efficiency.

[0032] In order to ensure that the feeding amount and the discharging amount of the temporary storage chamber are consistent within the same time and realize quantitative delivery, the volume of the four temporary storage chambers is V2, and the areas of the feeding port 15 and the discharging port 16 are the same. At the same time, the areas of the feeding port 21 and the feeding port 52 are also the same as the areas of the feeding port 15 and the discharging port 16. In this embodiment, V2 is 5ml, that is, the amount of one portion of detergent is 5ml. In actual application, the volume of the temporary storage chamber can be adjusted according to actual demand; in order to make the detergent stored in the storage chamber 20 meet the multiple filling and multiple delivery of the temporary storage chamber, the volume V1 of the storage chamber 20 is much larger than the volume V2 of the temporary storage chamber. In this embodiment, V1 is 600ml.

[0033] In order to prevent the agglomerated detergent from entering the temporary storage chamber, affecting the normal delivery of the device and reducing the delivery accuracy, a crushing assembly 30 is arranged directly above the feeding port 21, and the crushing assembly 30 includes a first crushing wheel 31 and a second crushing wheel 32 arranged adjacent to each other. The two crushing wheels are rotatably arranged in the storage chamber 20 through a first transmission shaft 33 and a second transmission shaft 34 respectively, and the two crushing wheels rotate in opposite directions under the drive of the driving assembly to crush the agglomerated detergent; in order to fully crush the agglomerated detergent and prevent the un-crushed agglomerated detergent from entering the temporary storage chamber, the first transmission shaft 33 and the second transmission shaft 34 are both arranged perpendicular to the dropping direction of the detergent, and the first crushing wheel 31 and the second crushing wheel 32 cover the entire discharge path of the detergent; the first transmission shaft 33 and the second transmission shaft 34 are both mounted on the mounting frame 35 and are limited by the limiting plate 36.

[0034] The driving assembly includes a motor 41, the output shaft of the motor 41 has an extension shaft 42, a first driving gear 43 is fixedly provided on the output shaft, a second driving gear 44 is fixedly provided on the extension shaft 42, the second driving gear 44 is coaxially arranged with the first driving gear 43, and is located above the first driving gear 43, wherein the first driving gear 43 is meshed with a first passive gear 45 that drives the temporary storage 10 to rotate, the first passive gear 45 is fixedly sleeved on the upper end of the temporary storage 10, and the second driving gear 44 is meshed with a second passive gear 46 that drives the rolling wheel to rotate, and a power source is used to drive the temporary storage 10 and the rolling wheel at the same time, saving energy. It can be easily operated, and can simplify the overall structure of the device and reduce manufacturing costs; the second driving gear 44 and the second passive gear 46 are both bevel gears, and the axis angle between the two bevel gears is 90 degrees. The second passive gear 46 is fixed to the end of the first transmission shaft 33. The first transmission shaft 33 is also coaxially fixed with a third passive gear 47. The third passive gear 47 is meshed with a fourth passive gear 48 fixed on the second transmission shaft 34. By setting two bevel gears, the transmission direction is changed. The structure is simple and the transmission is reliable, so that the transmission shaft of the crushing wheel is perpendicular to the rotating shaft of the temporary storage device 10, thereby ensuring that the detergent is fully crushed.

[0035] In order to prevent leakage of the temporary storage chamber during the process of filling detergent, a feeding pipe 22 extending toward the upper end surface of the temporary storage chamber 10 is formed below the feeding port 21, and an upper sealing ring 23 abutting against the upper end surface of the temporary storage chamber 10 is mounted on the lower end of the feeding pipe 22. A first pressing spring 24 for pressing the upper sealing ring 23 down to the upper end surface of the temporary storage chamber 10 is also mounted on the feeding pipe 22. The provision of the first pressing spring 24 can reduce the gap between the upper sealing ring 23 and the upper end surface of the temporary storage chamber 10 to avoid leakage and reduce the friction resistance during the rotation of the temporary storage chamber 10; in the process of the temporary storage chamber 10 driving the temporary storage chamber to rotate, the upper sealing ring 23 that is always mounted on the feeding pipe 22 can also scrape out excess detergent in the temporary storage chamber and allow it to enter the next temporary storage chamber, thereby ensuring that the loading amount of each temporary storage chamber is consistent to achieve quantitative delivery.

[0036] The sealing assembly includes a sealing plate 51 and a sealing gasket 53 located between the temporary storage 10 and the sealing plate 51. The sealing plate 51 and the sealing gasket 53 are installed perpendicular to the central axis of the temporary storage 10. The feeding port 52 is opened on the sealing plate 51. The sealing gasket 53 is formed with lower sealing rings 531 with the same number as the annular convex edge 161. Each annular convex edge 161 is fitted with a lower sealing ring 531. The sealing gasket 53 rotates with the temporary storage 10. A second downward pressure spring 54 is also provided between the lower end surface of the temporary storage 10 and the sealing gasket 53 to press the sealing gasket 53 toward the sealing plate 51. The second downward pressure spring 54 can reduce the pressure between the lower sealing ring 531 and the sealing gasket. The gap between the plates 51 can also reduce the frictional resistance when the temporary storage device 10 rotates. The setting of the sealing assembly can effectively solve the problem that the detergent will leak out from the discharge port 16 of the temporary storage chamber during the rotation of the temporary storage device 10, and ensure that the detergent in the temporary storage chamber can all reach the top of the feeding port 52 and be discharged from the feeding port 52 to achieve accurate delivery. The temporary storage chamber does not need to be separately provided with a cover for sealing the discharge port 16, nor does it need to be separately provided with a power device and control system for controlling the opening and closing of the cover, so that the detergent can be carried and delivered, making the structure of the entire device more compact and simple, and easy to control.

[0037] A sealing assembly is also provided below the feeding port 52, and the sealing assembly includes a side cover 65, a mounting plate 61 and a sealing cover 62. The mounting plate 61 is fixedly mounted on the inner wall of the side cover 65, and the sealing cover 62 is rotatably mounted on the mounting plate 61 through a rotating shaft 63. A force-bearing protrusion 631 is formed at the end of the rotating shaft 63. When the force-bearing protrusion 631 is subjected to force, the rotating shaft 63 can be driven to rotate, so that the sealing cover 62 is pressed down and opened. A reset torsion spring 64 that can reset the sealing cover 62 is also sleeved on the rotating shaft 63. The setting of the sealing assembly can achieve active moisture-proofing, so that the sealing cover 62 is always in a closed state when no force is applied to prevent liquid and water vapor in the dishwasher from entering the temporary storage chamber and preventing the detergent from getting damp. In order to further improve the moisture-proofing effect, a rubber pad 66 is also provided on the inner wall of the sealing cover 62; a connecting rod 17 is vertically fixedly mounted at the center of the lower end surface of the temporary storage device 10, and the lower end of the connecting rod 17 is connected to a The rotating stopper 80 has a circumferential array of convex columns the same number as the temporary storage chambers, and the convex columns are located in the middle of two adjacent temporary storage chambers. The convex column A81 is located between the first temporary storage chamber 11 and the second temporary storage chamber 12, the convex column B82 is located between the second temporary storage chamber 12 and the third temporary storage chamber 13, the convex column C83 is located between the third temporary storage chamber 13 and the fourth temporary storage chamber 14, and the convex column D84 is located between the fourth temporary storage chamber 14 and the first temporary storage chamber 11. The convex columns rotate with the rotating stopper 80 and apply force to the force-bearing convex block 631 in turn. Through the cooperation between the rotating stopper 80 and the force-bearing convex block 631, the automatic opening and closing of the sealing cover 62 can be realized, and the rotating stopper 80 is connected to the temporary storage chamber 10 through the connecting rod 17, so that the rotating stopper 80 can rotate with the temporary storage chamber 10, and there is no need to set up a separate power for opening the sealing cover 62.

[0038] A sensor is also provided between adjacent temporary storage chambers. The sensor is provided at one end of the discharge port 16 of the temporary storage chamber. The sensor transmitting end A71 is located between the first temporary storage chamber 11 and the second temporary storage chamber 12. The sensor transmitting end B72 is located between the second temporary storage chamber 12 and the third temporary storage chamber 13. The sensor transmitting end C73 is located between the third temporary storage chamber 13 and the fourth temporary storage chamber 14. The sensor transmitting end D74 is located between the fourth temporary storage chamber 14 and the first temporary storage chamber 11.

[0039] The working process of the powder detergent dispensing device disclosed in this embodiment is as follows: Fig.11In the initial state, the feed port 21 of the storage chamber 20 is aligned with the feed port 15 of the first temporary storage chamber 11 on the storage device, and the first temporary storage chamber 11 is already filled with detergent, and the other three temporary storage chambers are empty. When the device is powered on, the motor 41 drives the first driving gear 43 to rotate clockwise, and the first driving gear 43 meshes with the first passive gear 45, so that the temporary storage 10 rotates counterclockwise with its own central axis as the rotation axis. When the temporary storage 10 rotates 90° counterclockwise, the sensor transmitting end B72 also rotates 90° counterclockwise, and the sensor transmitting end B72 coincides with the sensor receiving end 75. The sensor transmitting end B72 sends a signal to the sensor receiving end 75, and the sensor receiving end 75 transmits the signal to the controller. The controller controls the motor 41 to stop working and delay waiting. At this time, the feed port 15 of the second temporary storage chamber 12 is facing the feed port 21 of the storage chamber 20, and the storage chamber 20 fills the second temporary storage chamber 12 with detergent. When the controller delay ends, the motor 41 is powered on again, and the motor 41 drives the temporary storage 10 to rotate counterclockwise again. When the temporary storage 10 further rotates to 135°, the connecting rod 17 of the temporary storage 10 drives the rotating block 80 to rotate, and the boss D84 on the rotating block 80 applies force to the force-bearing protrusion 631 on the rotating shaft 63, so that the sealing cover 62 gradually opens. At this time, the detergent in the first temporary storage chamber 11 begins to slowly enter the washing chamber of the dishwasher. When the temporary storage 10 further rotates to 180°, the sensor transmitting end C73 coincides with the sensor receiving end 75, and the sensor receiving end 75 transmits a signal to the controller, and the controller controls the motor 41 to stop working and delay waiting. At this time, the discharge port 16 of the first temporary storage chamber 11 is facing the feeding port 52, and the boss D84 on the rotating block 80 exerts force on the force-bearing protrusion on the rotating shaft 63. 631 applies force to fully open the sealing cover 62, and the detergent in the first temporary storage chamber 11 is ejected from the feeding control port 52. The device completes a detergent feeding process. While feeding in the first temporary storage chamber 11, the feeding port 15 of the third temporary storage chamber 13 is aligned with the feeding port 21 of the storage chamber 20, and the storage chamber 20 fills the third temporary storage chamber 13 with detergent. When the third temporary storage chamber 13 is filled with detergent and the controller delay ends, the motor 41 continues to work, and the protrusion D84 on the rotating block 80 is separated from the force-bearing protrusion 631 on the rotating shaft 63. The sealing cover 62 is closed by the torsion of the reset torsion spring 64, and the temporary storage chamber 10 continues to fill the next temporary storage chamber and implement the next detergent feeding action. While the motor 41 drives the temporary storage chamber 10 to rotate, it drives the rolling assembly 30 to work and break up the agglomerated detergent.

[0040] During the operation of the device, the driving device is generally a motor 41, and may also be other devices with a rotational driving function. The driving device in this embodiment is a synchronous motor; the speed S1 of the synchronous motor is 15RPM, the speed ratio i of the first driving gear 43 and the buffer 10 is 2:1, and the speed S2 of the buffer 10 is 7.5RPM.

[0041] During the operation of the device, the detergent is dropped by gravity. In order to ensure that the detergent can be completely put into the washing chamber from the temporary storage chamber, the delay time T1 of the controller is greater than the drop time T2 of the detergent in the temporary storage chamber. The delay time T1 of this embodiment is 1s, and the drop time T2 of the detergent when the temporary storage chamber and the delivery channel coincide is 0.5s; in order to ensure that the detergent in the storage chamber 20 can fully fill the temporary storage chamber, the delay time T1 of the controller should be greater than the time T3 of loading the detergent in the temporary storage chamber. The delay time T1 of this embodiment is 1s, and the filling time T3 of the detergent in the temporary storage chamber is 0.5s, and the loading of detergent and the delivery of detergent are carried out simultaneously, T3 and T2 coincide, and both occur in the delay time T1. The convex column on the rotating block 80 contacts the force-bearing convex block 631, so that the sealing cover 62 is gradually opened, and the time T4 required for the sealing cover 62 to be fully opened is 2s, that is, the time T0 required to deliver a portion of detergent = T1 +T4=3s; The size of the delivery time T0 is the delivery efficiency, which depends on the speed ratio i (i=S1 / S2) between the motor 41 speed S1 and the storage speed S2. Therefore, the transmission ratio i can be adjusted as needed to enable the automatic delivery device to achieve different delivery efficiencies; during the operation of the device, the rotating block 80 is fixed to the temporary storage device 10 through the connecting rod 17, and the speed S3 of the rotating block 80 is the same as the speed S2 of the storage device 6.
