Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning equipment, in particular to a dispenser and a dishwasher. Background Art

[0002] Dishwashers are household automatic cleaning appliances, increasingly popular in households due to their time-saving, labor-saving, thorough cleaning, and disinfecting properties. Current dishwashers typically use solid dishwashing powder as a detergent. A dispenser is typically located inside the dishwasher door. The dispenser contains a solid compartment for dishwashing powder (blocks) and a liquid compartment for rinse aid, respectively. This allows for single-addition and multiple automatic dosing of dishwashing powder (blocks) and rinse aid during the wash cycle.

[0003] With the widespread use of liquid detergent, a liquid compartment needs to be added to the dispenser to hold the liquid detergent. Currently, on most dishwasher dispensers, liquid detergent, like solid detergent (dishwashing powder), is added and dispensed in a single addition. This results in the need to add liquid detergent or solid detergent (dishwashing powder or tablets) every time you wash dishes, resulting in frequent repetitive operations and cumbersome operation and control. Some dispensers that can add once and dispense multiple times use the same functional components as rinse agents to achieve the multiple dispensing function. There is no linkage control relationship between the multiple compartments, and the functions are simply stacked, resulting in the stacking of structural parts, excessive electrical components, and low integration. As a result, the dispenser takes up a lot of space and is too expensive, which is not conducive to the widespread promotion of the product. Utility Model Content

[0063] The embodiment of the present utility model first provides a dispenser for adding and dispensing detergents on a dishwasher. As Figure 1 shown, the dispenser includes a main body 400 and a solid bin 100, a first liquid bin 200 and a second liquid bin 300 provided on the main body 400. The main body 400 is generally arranged and fixed on the inner side of the door of the dishwasher and is located in the washing bin after the door is closed. The solid bin 100 is used for adding and dispensing solid detergents, such as dishwashing powder or dishwashing blocks. The solid bin 100 has a bin opening for both adding and dispensing. The first liquid bin 200 is used for adding and storing liquid detergents (also called dishwashing liquid). The first liquid bin 200 is provided with a first replenishing port and a first liquid outlet 201. The first replenishing port is used for adding a sufficient amount of liquid detergent into the first liquid bin 200 at one time, and the first liquid outlet 201 is used for dispensing a specified amount of liquid detergent into the washing bin multiple times, enabling multiple automatic dispensings after one addition.

[0064] The dispenser provided by the embodiment of the present utility model further includes a sliding seal assembly 1, a first dosing assembly 2, a second dosing assembly 3, and a driving assembly 4. The sliding seal assembly 1 is slidably connected to the main body 400 to slidably open or close the hatch of the solid bin 100 for the first addition and first dosing of solid detergent; the first dosing assembly 2 is arranged at the first liquid outlet 201 of the first liquid bin 200 to control the dosing of liquid detergent; the second dosing assembly 3 is arranged at the second liquid outlet 301 of the second liquid bin 300 to control the dosing of liquid rinse aid; the output end of the driving assembly 4 is switchably connected to the sliding seal assembly 1, the first dosing assembly 2, and the second dosing assembly 3. When the output end of the driving assembly 4 rotates forward, it drives the sliding seal assembly 1 and the first dosing assembly 2 to open in sequence, and the solid bin 100 and the first liquid bin 200 perform the first dosing action in sequence; when the output end of the driving assembly 4 rotates reversely, the second dosing assembly 3 opens, and the second liquid bin 300 performs the first dosing action.

[0065] The dispenser provided by the present utility model realizes the separate dosing control of the solid bin 100, the first liquid bin 200, and the second liquid bin 300 through the forward and reverse rotation actions of a driving assembly 4, solves the problems of low integration degree and large occupied space of the dispenser, and is beneficial to reducing the part cost. The present utility model realizes the function of one-time addition and one-time dosing of solid detergent, as well as the function of one-time addition and multiple dosing of liquid detergent and liquid rinse aid, realizes the multiple automatic dosing of liquid detergent and liquid rinse aid, has a simple control method, and improves the automation degree of the dishwasher.

[0066] In some embodiments, the sliding seal assembly 1 includes a sliding cover 11, a lever 12, and a locking block 13. The sliding cover 11 is elastically connected to the main body 400 and can slidably open or close the hatch of the solid bin 100. A locking groove 111 is provided on the sliding cover 11; a rotating shaft 121 is provided on the lever 12, and the rotating shaft 121 is rotatably connected to the main body 400. One end of the lever 12 is connected to the output end of the driving assembly 4, and the driving assembly 4 is configured to drive the lever 12 to rotate around the main body 400 when rotating forward; the locking block 13 is arranged on the rotating shaft 121 and the locking block 13 cooperates with the locking groove 111 for clamping. When the locking block 13 is clamped with the locking groove 111, the sliding cover 11 closes the hatch of the solid bin 100 and stores elastic energy; when the rotating shaft 121 rotates with the lever 12, it drives the locking block 13 to unlock the sliding cover 11, and the sliding cover 11 slides open the hatch of the solid bin 100 under the action of the stored elastic energy.

[0067] As Figures 2 - 3As shown, when the locking block 13 is engaged in the locking groove 111, the sliding cover 11 is locked to seal the solid storage bin 100. At this time, when the sliding cover 11 is locked, elastic energy is stored between the sliding cover 11 and the body 400. The bottom end of the rotating shaft 121 is penetrated by the driving rod 12 and can rotate synchronously with the driving rod 12. The top end of the rotating shaft 121 is provided with a linkage rod 122, which is fixedly connected to the locking block 13. The function of the linkage rod 122 is to set the position of the locking block 13 according to the internal space of the dispenser body 400. When the drive assembly 4 rotates forward, the driving rod 12 rotates around the body 400, and the rotating shaft 121 rotates accordingly. The top end of the rotating shaft 121 pulls the locking block 13 to unlock it from the locking groove 111. The sliding cover 11 slides open the port of the solid storage bin 100 under the elastic force of the elastic energy storage and remains open under the elastic force until it is locked again when solid detergent is manually added. It should be explained that the shifting lever 12 and the rotating shaft 121 may be connected via a bearing or a sleeve rod to ensure the stability of the rotation plane of the shifting lever 12 .

[0068] In some embodiments, the sliding seal assembly 1 further includes a first elastic member 14. The first elastic member 14 has two ends connected to the other end of the lever 12 facing away from the output end of the drive assembly 4 and the body 400, respectively. The first elastic member 14 is capable of returning to its original position after the rotational driving force of the lever 12 is unloaded. The first elastic member 14 is preferably a spring. The lever 12 is driven by the drive assembly 4 in a pulsed or periodic manner. With each toggle, the lever 12 rotates a certain angle, and the first elastic member 14 stores elastic energy. After the locking block 13 unlocks the sliding cover 11 with the locking groove 111, the lever 12 rapidly rotates and returns to its original position due to the stored elastic energy.

[0069] In some embodiments, the sliding sealing assembly 1 further includes a second elastic member 15 , the two ends of which are respectively connected to the body 400 and the sliding cover 11 . The sliding cover 11 can remain in an open state under the action of the second elastic member 15 .

[0070] The second elastic member 15 is a torsion spring, one end of which is fixed to the main body 400 and the other end to the sliding cover 11. When the sliding cover 11 is closed, the second elastic member 15 is compressed to store energy. When the locking block 13 is unlocked from the locking groove 111, the sliding cover 11 slides open and remains open under the action of the torsion spring, achieving a one-time dispensing of solid detergent. It will be understood that to improve the sliding guidance and stability between the sliding cover 11 and the main body 400, the sliding cover 11 and the main body 400 are respectively provided with a slider and a chute, and the slider is slidably connected within the chute.

[0071] In some embodiments, the output end of the drive component 4 is in sliding contact with the lever 12. The sliding contact method is beneficial for the output end of the drive component 4 to drive the lever 12 to disengage from the lever 12 after each rotation of a certain angle to release the drive, thereby facilitating the resetting of the lever 12 to limit the sliding cover 11 to the open position; the sliding contact method is beneficial for the output end of the drive component 4 to continue to drive the first delivery component 2 after driving the sliding sealing component 1 to move, thereby realizing the action of opening the solid bin 100 and the first liquid bin 200 in sequence with one rotation, saving control process and saving structural layout space.

[0072] In some embodiments, the first dispensing component 2 includes a connecting tube 21 and a tensioning wheel 22. The first liquid tank 200 is provided with a first liquid outlet 201 and a connecting hole 202. The two ends of the connecting tube 21 are respectively connected to the first liquid outlet 201 and the connecting hole 202. The first liquid outlet 201 and the connecting hole 202 are respectively connected to the dishwashing tank and the first liquid tank 200 at one end away from the connecting tube 21; the tensioning wheel 22 is fixedly connected to the output end of the driving component 4, and the connecting tube 21 is tensioned on the tensioning wheel 22. When the output end of the driving component 4 rotates forward, the tensioning wheel 22 can squeeze the liquid in the connecting tube 21 from the first liquid tank 200 into the dishwashing tank.

[0073] like Figure 3 , wherein the connecting hole 202 is a hole provided on the first liquid tank 200 for discharging liquid detergent, and the first liquid outlet 201 is a hole provided on the first liquid tank 200 and connected to the dishwashing tank. The liquid detergent is discharged from the first liquid tank 200 through the connecting hole 202 and enters the connecting pipe 21, and is discharged into the dishwashing tank through the connecting pipe 21 via the first liquid outlet 201, thereby achieving one-time delivery. It can be understood that the two ends of the connecting pipe 21 are respectively fixed at the connecting hole 202 and the first liquid outlet 201 to achieve fixed installation. The connecting pipe 21 is sleeved on the tensioning wheel 22. Under the tensioning and compression action of the tensioning wheel 22, the pressure inside the connecting pipe 21 changes, so that the liquid in the connecting pipe 21 can be introduced from one end to the other end, thereby achieving liquid detergent delivery control. It can be understood that the connecting pipe 21 is a flexible pipe, which is more conducive to the regulation and control of the pipe pressure between the connecting pipe 21 and the tensioning wheel 22.

[0074] In some embodiments, the tensioner 22 includes an axle 221 and a rotating wheel 222. The axle 221 is connected to the output end of the driving assembly 4. There are multiple rotating wheels 222. The multiple rotating wheels 222 are spaced apart on the circumferential edge of the axle 221. The connecting pipe 21 is sleeved on the multiple rotating wheels 222.

[0075] Take the three rotating wheels 222 as an example, Figure 3 and Figure 8, three rotating wheels 222 are arranged at intervals on the circumferential edge of the axle 221. When the output end of the driving assembly 4 drives or drives the axle 221 to rotate, the three rotating wheels 222 rotate accordingly, so that the communicating pipe 21 is alternately subjected to the wheel pressure of the three rotating wheels 222, and the internal pipe pressure changes, realizing the one-way flow of the liquid in the pipe. Preferably, the plurality of rotating wheels 222 are respectively rotatably connected to the axle 221, which can reduce the frictional wear between the rotating wheels 222 and the pipe wall of the communicating pipe 21. The first feeding assembly 2 provided by the embodiment of the present invention realizes feeding through the principle of the pipe pressure difference of the communicating pipe 21. Compared with the prior art, the structure is simple, and the use of structural parts such as mechanical pump bodies and valve bodies is reduced, the equipment cost is greatly reduced, the control method is simpler, which is beneficial to improving the integration degree of the dispenser. One rotation action of the output end of the driving assembly 4 sequentially realizes the feeding of the solid detergent and the feeding of the liquid detergent, meets different detergent use requirements, and realizes the automation requirement of one-time addition and multiple automatic feeding of the liquid detergent.

[0076] In some embodiments, the second feeding assembly 3 includes a first pull rod 31 and a second pull rod 32. A first pin shaft 4222 is provided at the output end of the driving assembly 4. At both ends of the first pull rod 31, one is provided with a first long hole 311 extending in the second direction, and the other end is provided with a second pin shaft 312. The first pin shaft 4222 is inserted into the first long hole 311; a second long hole 321 extending in the first direction is provided on the second pull rod 32, and the second pin shaft 312 is inserted into the second long hole 321. The second pull rod 32 can open or close the second liquid outlet 301; when the output end of the driving assembly 4 rotates in the reverse direction, the first pin shaft 4222 slides along the first long hole 311 and drives the first pull rod 31 to move in the first direction, and drives the second pull rod 32 to move in the first direction through the second pin shaft 312. The second pull rod 32 opens the second liquid outlet 301. The first direction (X direction) and the second direction (Y direction) are perpendicular to each other along the length direction and the width direction of the main body 400.

[0077] It can be understood that a first pin shaft 4222 is provided at the output end of the driving assembly 4, and the first pin shaft 4222 is arranged away from the rotation center of the output end of the driving assembly 4, so that the rotation of the first pin shaft 4222 is an eccentric rotation. When the output end of the driving assembly 4 rotates, since the first pin shaft 4222 is slidably installed in the first long hole 311, the output end of the driving assembly 4 drives the first pin shaft 4222 to perform a circular motion around the rotation center of the output end of the driving assembly 4. The circular motion of the first pin shaft 4222 is converted into the movement of the first pull rod 31. When the first pull rod 31 moves to the farthest distance from the second pull rod 32, the second pull rod 32 also moves to the farthest distance and opens the second liquid outlet 301, realizing one-time feeding of the liquid rinse aid. When the first pin shaft 4222 rotates to the closest distance to the second pull rod 32, the second pull rod 32 seals the second liquid outlet 301 again.

[0078] In a preferred embodiment, the second dispensing assembly 3 further includes a sealing plug 33 disposed at an end of the second pull rod 32 away from the first pull rod 31, and the sealing plug 33 can seal the second liquid outlet 301 of the second liquid chamber 300. As Figure 5 , the shape of the sealing plug 33 is adapted to that of the second liquid outlet 301 for easy insertion and sealing. The sealing plug 33 is generally made of elastic rubber. The moving directions of the first pull rod 31 and the second pull rod 32 are along the first direction X. In a preferred solution, an annular boss 331 is provided on the circumferential direction of the sealing plug 33, and a buckle 302 is provided at the second liquid outlet 301 of the second liquid chamber 300. When the sealing plug 33 is inserted into the second liquid outlet 301 for sealing, the buckle 302 can be engaged with the annular boss 331 to realize the engagement of the sealing plug 33.

[0079] In some embodiments, the second dispensing assembly 3 further includes a third elastic member 34 sleeved on the second pull rod 32, and both ends of the third elastic member 34 respectively abut against the sealing plug 33 and the body 400. As Figure 5 , wherein, the third elastic member 34 is always in an elastic tension state. The third elastic member 34 is preferably a spring sleeved on the second pull rod 32. When the second pull rod 32 moves to the farthest distance from the second liquid chamber 300, the third elastic member 34 has the maximum elasticity. When the second pull rod 32 moves to the closest distance from the second liquid chamber 300, the sealing plug 33 is inserted into the second liquid outlet 301 to achieve sealing; at the same time, the third elastic member 34 is tensioned and installed between the body 400 and the second pull rod 32, so that the second pull rod 32 has a movement tendency towards the second liquid chamber 300, further pressing the sealing plug 33 tightly sealed at the second liquid outlet 301.

[0080] In the embodiment of the present utility model, by providing the second dispensing assembly 3, through the first pin shaft 4222 eccentrically provided on the output end of the driving assembly 4, every time the output end of the driving assembly 4 rotates in reverse for one week, the second liquid chamber 300 conducts a liquid rinse aid dispensing, realizing the multiple automatic dispensing control of the liquid rinse aid and meeting the rinsing requirements. In summary, a driving assembly 4 realizes the three-in-one combined drive of solid detergent, liquid detergent and liquid rinse aid respectively through forward rotation and reverse rotation, with high integrated control degree, few electromagnetic parts, saving equipment cost and occupied space, and having good application prospects.

[0081] In some embodiments, the driving assembly 4 includes a motor 41, a first clutch assembly 42, and a second clutch assembly 43. Among them, the output end of the motor 41 is a rotational output, capable of realizing forward and reverse driving. The first clutch assembly 42 is connected to the output end of the motor 41. When the motor 41 rotates forward, the first clutch assembly 42 is separated from the second dosing assembly 3. When the motor 41 rotates in reverse, the first clutch assembly 42 is engaged with the second dosing assembly 3 to realize the control of reverse dosing of the liquid rinse aid. The second clutch assembly 43 is drivingly connected to the first clutch assembly 42. When the motor 41 rotates forward, the second clutch assembly 43 is engaged with the first dosing assembly 2 and the second clutch assembly 43 is engaged with the sliding seal assembly 1. When the motor 41 rotates in reverse, the second clutch assembly 43 is separated from the first dosing assembly 2 and the second clutch assembly 43 is separated from the sliding seal assembly 1.

[0082] In the embodiments of the present invention, the first clutch assembly 42 and the second clutch assembly 43 are arranged at the output end of the driving assembly 4, which is convenient for realizing the separate control of the output end of the driving assembly 4 under the conditions of forward rotation and reverse rotation. Through the separation and engagement properties of the first clutch assembly 42 and the second clutch assembly 43, the dosing control of various detergents of the dispenser is realized. Among them, the first clutch assembly 42 has separation and engagement with the second dosing assembly 3. When the motor 41 rotates in reverse, the first clutch assembly 42 is engaged with the second dosing assembly 3, and the second clutch assembly 43 is separated from the first dosing assembly 2 and the sliding seal assembly 1. At this time, the motor 41 controls the second liquid bin 300 to dose the liquid rinse aid. When the motor 41 rotates forward, the first clutch assembly 42 is separated from the second dosing assembly 3, and the second clutch assembly 43 is engaged with the first dosing assembly 2 and the sliding seal assembly 1. At this time, the motor 41 controls the solid bin 100 to dose the solid detergent and the first liquid bin 200 to dose the liquid detergent.

[0083] In some embodiments, a worm and worm gear assembly is provided at the output end of the motor 41, and the first clutch assembly 42 is drivingly connected to the worm and worm gear assembly.

[0084] The worm and worm gear assembly includes a worm 411 and a worm gear 412. The output end of the motor 41 is fixedly connected to the coaxially arranged worm 411. The worm gear 412 is drivingly connected to the worm 411, and the worm gear 412 is drivingly connected to the first clutch assembly 42 to realize the transfer of the rotation of the output end of the motor 41 to the rotation of the first clutch assembly 42. By providing the worm and worm gear assembly, the change of the transmission direction is realized, which is beneficial to the structural layout in the limited and narrow space of the dispenser body 400.

[0085] In some embodiments, the first clutch assembly 42 includes a first gear 421 and a second gear 422. The first gear 421 has a first outer gear ring 4211 and a first inner gear ring 4212. The second gear 422 has a second outer gear ring 4221. The second outer gear ring 4221 meshes with the first inner gear ring 4212. The teeth of the first inner gear ring 4212 and the second outer gear ring 4221 are all one-way teeth to achieve one-way drive connection. A first pin shaft 4222 is provided on the second gear 422.

[0086] It can be understood that there is a drive connection between the first clutch assembly 42 and the second clutch assembly 43. The function of setting the second gear 422 is to realize the separation and engagement control between the first clutch assembly 42 and the second feeding assembly 3. Therefore, when the motor 41 rotates in the reverse direction, the first gear 421 of the first clutch assembly 42 rotates and drives the second gear 422 to rotate. The second gear 422 drives the first pin shaft 4222 to rotate. The first pin shaft 4222 can be fixedly arranged on the gear surface of the second gear 422 facing away from the first gear 421. When the second gear 422 rotates, the first pin shaft 4222 moves in a circular motion around the rotation center of the second gear 422, and thus has a pulling effect on the first pull rod 31. The first pin shaft 4222 is vertically inserted downward into the first long hole 311 in the gear surface of the second gear 422. The outer diameter of the first pin shaft 4222 is equal to the width of the first long hole 311. The length of the first long hole 311 is equal to the radius of the circular motion of the first pin shaft 4222, so that the first pull rod 31 has a definite moving direction, converting the circular motion of the first pin shaft 4222 into the movement of the first pull rod 31. When the motor 41 rotates forward, since the first inner gear ring 4212 and the second outer gear ring 4221 are one-way teeth, after the rotation direction of the first gear 421 changes, the second gear 422 does not perform a drive movement, realizing the separation between the first clutch assembly 42 and the second feeding assembly 3.

[0087] In some embodiments, the second clutch assembly 43 includes a third gear 431 and a fourth gear 432. The third gear 431 has a third outer gear ring 4311 and a second inner gear ring 4312. The fourth gear 432 has a fourth outer gear ring 4321. The third outer gear ring 4311 meshes and drives with the first outer gear ring 4211. The fourth outer gear ring 4321 meshes with the second inner gear ring 4312. The teeth of the second inner gear ring 4312 and the fourth outer gear ring 4321 are all one-way teeth to achieve one-way drive connection, and the helix directions of the one-way teeth of the first inner gear ring 4212 and the first inner gear ring 4212 are opposite. A tension wheel 22 of the first feeding assembly 2 is connected to the gear shaft 221 of the fourth gear 432 to drive the tension wheel 22 to rotate.

[0088] In this embodiment, the clutch principles of the first clutch assembly 42 and the second clutch assembly 43 are the same, but the separation and engagement directions are opposite. When the motor 41 rotates forward, the first gear 421 drives the third gear 431 to rotate, and the second gear 422 does not transmit motion, realizing the separation of the first clutch assembly 42 and the second dosing assembly 3; the third gear 431 drives the fourth gear 432 to rotate, and a coaxial fixed tension pulley 22 is connected to the fourth gear 432. The rotation of the tension pulley 22 realizes the dosing action of the first dosing assembly 2; when the motor 41 rotates in reverse, the first gear 421 drives the third gear 431 and the second gear 422 to rotate. Due to the action of the one-way teeth, there is no transmission motion between the third gear 431 and the fourth gear 432, realizing the separation of the second clutch assembly 43 and the first dosing assembly 2.

[0089] In some embodiments, the drive assembly 4 further includes a cam 44. The cam 44 is fixedly connected to the tension pulley 22 and can rotate synchronously with the tension pulley 22. The cam 44 is in sliding contact with the sliding seal assembly 1.

[0090] In this embodiment, the cam 44, the tension pulley 22, and the first gear 421 are coaxially fixed and arranged for synchronous rotation drive. When the motor 41 rotates forward, the first gear 421, the third gear 431, and the fourth gear 432 are sequentially driven to move. The fourth gear 432 drives the cam 44 to rotate. The cam 44 is in sliding contact with the lever 12 of the sliding seal assembly 1, driving the lever 12 to rotate a certain angle to realize the action of the sliding cover 11 opening the solid bin 100; when the motor 41 continues to rotate forward, the cam 44 rotates past the lever 12, and the lever 12 resets; at this time, the pressure in the connecting pipe 21 changes under the action of the tension pulley 22. The liquid detergent in the first liquid bin 200 passes through the communication hole 202, the connecting pipe 21, and the first liquid outlet 201, and then the liquid detergent is dosed once in the dishwashing bin. As shown in Figure 8 As shown, a plugging assembly cooperating with the wheel shaft 221 is preferably provided on one side of the cam 44 facing the wheel shaft 221, so that the cam 44 can be plugged and cooperated with the wheel shaft 221, and the connecting pipe 21 is clamped between the cam 44 and the wheel shaft 221 to facilitate the stable installation of the connecting pipe 21.

[0091] In some embodiments, the dispenser further includes a liquid level sensing module, and the liquid level sensing module is arranged in the first liquid bin 200 and the second liquid bin 300 to detect the liquid level height.

[0092] The liquid level sensing module can adopt a liquid level sensor, which is used to detect the liquid level height in the first liquid bin 200 and the second liquid bin 300 in real time, so as to supplement the liquid detergent and the liquid rinse aid in time according to the prompt.

[0093] The present utility model also provides a dishwasher, including the dispenser provided in any of the above embodiments.

[0094] The dishwasher provided by the present utility model includes the dispenser provided by the present utility model. By the forward and reverse movements of the driving assembly 4, the separate feeding control of the solid bin 100, the first liquid bin 200 and the second liquid bin 300 is realized, solving the problems of low integration degree and large occupied space of the dispenser, saving solenoid valve parts and reducing costs. Specifically, the dispenser is arranged inside the door body of the dishwasher. When the door body is closed, the dispenser is located inside the dishwashing bin.
