Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dispenser that allows for step-by-step control of powder and liquid dispensing. Background Technology

[0002] Chinese invention patent CN109363604B discloses a dishwasher dispenser that allows for independent dispensing of detergent powder and dishwashing liquid. The dispenser uses ball bearings that move in three separate compartments and, through the cooperation of the ball bearings, a first limiting post, and a second limiting post, restricts the swing of the transmission rod that opens the detergent powder box or the movement of the shaft that opens the rinse aid sealing device, thereby enabling the separate dispensing of detergent powder and rinse aid.

[0003] After a period of use, the rigid ball bearings rub against the first limit post, the second limit post, and the housing, causing the ball bearings to easily become misaligned in the three receiving slots. This can lead to malfunctions in the transmission rod that restricts the opening of the dishwashing powder box or in the movement of the shaft. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to propose a dispenser that allows for step-by-step control of powder and liquid dispensing, thereby overcoming the defects of the ball bearing structure and solving the problem of step-by-step dispensing of dishwashing powder and rinse aid, including:

[0005] A drive component, wherein a second through hole is provided on the drive component, and the drive component controls the dispensing of dishwasher detergent;

[0006] A sealing assembly, wherein a first through hole is provided on the sealing assembly, and the sealing assembly controls the dispensing of brightening agent liquid;

[0007] A transmission assembly, wherein a transmission component is provided on the transmission assembly;

[0008] The extension direction of the transmission component is toward the first through hole and the second through hole;

[0009] The transmission component, the first through hole, and the second through hole cooperate with each other, so that the driving component drives the sealing component and the transmission component to move in stages, thereby controlling the powder and liquid distribution of the distributor.

[0010] In some embodiments, the drive assembly includes a first connector and a drive member, the first connector being connected to the driver, and the first connector having a second through hole.

[0011] The sealing assembly includes a second connector and a seal, the second connector and the seal are connected, and the second connector is provided with the first through hole;

[0012] The transmission assembly includes a third connector, the transmission member is disposed on the third connector, and the first connector is located between the second connector and the third connector;

[0013] The other end of the first connector connected to the driver is provided with a transmission part, which transmits the movement of the driver to control the dispensing of the dishwashing powder.

[0014] In some embodiments, the first connector is a first connecting plate, the seal is a sealing head, the second connector is a second connecting plate, the transmission assembly is a swing plate, one end of the transmission assembly is fixed, the transmission member is a connecting rod, and the transmission part is an engaging part.

[0015] In some embodiments, the dispenser that allows for step-by-step control of powder and liquid dispensing further includes a chassis, a powder box, and a polishing agent panel. The powder box and the polishing agent panel are located on the same side, while the powder box, the polishing agent panel, and the chassis are arranged opposite to each other. The drive assembly, the sealing assembly, and the transmission assembly are disposed on the side of the chassis opposite to the polishing agent panel and the powder box.

[0016] In some embodiments, the dispenser with step-by-step control of powder and liquid dispensing further includes a lid opening assembly, which is disposed in the chassis, the transmission unit is connected to the lid opening assembly, and the lid opening assembly is connected to the powder box.

[0018] In some embodiments, the transmission assembly includes a starting station, a powder feeding station, a waiting station, and a liquid feeding station;

[0019] When the transmission assembly is located at the starting position, the output end of the driver is in the extended state, and the end of the transmission member passes through the second through hole and abuts against the second connector;

[0020] When the transmission component is in the powder dispensing station, the output end of the driver is in the retracted state, and the first connector drives the transmission part and the opening component to rotate synchronously to open the powder box and complete the dispensing of dishwashing powder. At the same time, the transmission component passes through the second through hole and the first through hole.

[0022] When the transmission component is in the liquid dispensing position, the output end of the driver is retracted. At this time, the transmission component pulls the first connector and the second connector to move synchronously toward the driver. The second connector drives the seal to leave the output through hole, thereby completing the dispensing of the brightening agent.

[0023] In some embodiments, the center of gravity of the transmission assembly is located on the side of the transmission member facing the driver;

[0024] The transmission assembly is also provided with a suspension through hole, which is located on the top of the third connector on the side away from the driver. The suspension through hole is used to allow the third connector to rotate around the suspension through hole.

[0028] The chassis has a fixed shaft on the side opposite to the powder box and the brightener panel; the first connector also has a fixing part;

[0029] The fixed part and the rotating part are spaced apart, with the fixed part located between the first connector and the rotating part; one end of the tension spring is fixed to the fixed shaft, and the other end of the tension spring is fixed to the fixed part.

[0030] This application achieves efficient and stable distribution control of powder and liquid dispensing by cooperating with the transmission component, the first through hole, and the second through hole, thereby enabling the drive component to drive the sealing component and the transmission component in stages. This is achieved at a lower cost. Attached Figure Description

Detailed Implementation

[0041] The following is combined Figures 1-8 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0042] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] A dispenser that allows for step-by-step control of powder and liquid dispensing is installed on the inner side of a foldable door panel of a dishwasher. It includes a driver 4, a sealing assembly 5, a transmission rod 7, and a cover opening assembly 8, which are respectively installed on the back of a chassis 1. The front of the chassis 1 is provided with a rinse aid metering chamber 13, and also includes a swing plate 6.

[0045] The swing plate 6 is provided with a suspension through hole 61 and a connecting rod 62; the suspension through hole 61 is located near the top corner of the swing plate 6; the connecting rod 62 is located at the lower end of the swing plate 6 and extends horizontally away from the door panel; the swing plate 6 is swayably suspended from the chassis 1 through the suspension through hole 61.

[0046] The sealing assembly 5 includes a second connecting plate 51, which is located at one end of the sealing assembly 5 near the driver 4, and the second connecting plate 51 is provided with a first through hole 510.

[0047] The transmission rod 7 includes a first connecting plate 71 and an engaging portion 72, the middle of which is rotatable; the first connecting plate 71 has a second through hole 710; the first connecting plate 71 is located at the upper end of the transmission rod 7, the second through hole 710 penetrates the first connecting plate 71, and one side of the first connecting plate 71 is connected to the output end of the driver 4; the engaging portion 72 is located at the lower end of the transmission rod 7, and engages with the opening assembly 8 for opening the powder box 3; the first through hole 710 is located near the side of the second through hole 710 facing the driver 4; the connecting rod 62 is inserted into the second through hole 710, and the end of the connecting rod 62 abuts against the second connecting plate 71;

[0048] When the output end of the driver 4 retracts and pulls the first connecting plate 71 closer, the first connecting plate 71 drives the lower end of the swing plate 6 to swing, so that the end of the connecting rod 62 passes through the second through hole 710 and extends into the first through hole 510.

[0049] like Figure 9 As shown, Figure 9 This is a simplified diagram showing the positional relationship between the first connecting plate 71, the second connecting plate 51, and the transmission rod 7 in the starting position of the distributor of the present invention, which allows for step-by-step control of powder and liquid feeding. To ensure that the transmission rod 7 can smoothly fall into the first through hole 510 when it moves, the end of the connecting rod 62 abuts against the second connecting plate 51 at a certain angle, and the connection between the suspension shaft 16 and the swing plate 6 has a certain amount of room for movement and is not completely locked. Therefore, when the first connecting plate 71 drives the transmission rod 7 to move to the first through hole 510, the transmission rod 7 and the swing plate 6 will be subjected to their own gravity and fall into the first through hole 510, thereby realizing the engagement between the transmission rod 7 and the first through hole 510.

[0050] like Figure 1 This is a schematic diagram of the assembly structure of the driver 4, sealing assembly 5, swing plate 6, transmission rod 7 and opening assembly 8 of an embodiment of the dispenser for step-by-step control of powder and liquid feeding according to this utility model.

[0051] Figure 3 This is a structural diagram of the front of the chassis 1. The front of the chassis 1 represents the orientation of the front, and the rear represents the orientation of the back. The front of the chassis 1 in the diagram has a rinse aid storage chamber 11, a receiving chamber 12, a rinse aid metering chamber 13, a discharge channel 111, and a conveying channel 112. The receiving chamber 12 is used to hold the bottom box 33 of the powder box 3, and the bottom box 33 is used to hold the dishwashing powder. The groove wall of the rinse aid metering chamber 13 has an output through hole 130. The rinse aid storage chamber 11 is connected to the rinse aid metering chamber 13 through the conveying channel 112. The upper end of the discharge channel 111 is connected to the rinse aid metering chamber 13 through the output through hole 130, and the lower end of the discharge channel 111 is connected to the discharge hole of the rinse aid panel 2 to discharge the rinse aid flowing out from the output through hole 130.

[0052] like Figure 5 and Figure 6As shown, the connecting rod 62 is inserted into the second through hole 710, and the end of the connecting rod 62 abuts against the second connecting plate 51 but does not extend into the first through hole 510. At this time, the driver 4 can be activated, causing the output end of the driver 4 to retract and pull the first connecting plate 71 closer, and causing the lower end of the swing plate 6 to swing accordingly. When the end of the connecting rod 62 passes through the second through hole 710 and extends into the first through hole 510, the output end of the driver 4 stops retracting and immediately moves in the opposite direction, so that the output end of the driver 4 returns to the extended state, so as to avoid driving the sealing assembly 5 to move. When the first connecting plate 71 is pulled, it can drive the engaging part 72 to rotate, and the engaging part 72 drives the opening assembly 8 to rotate and open the powder box 3, thereby completing the addition of dishwashing powder to the dishwasher sink.

[0053] like Figure 7 As shown, when the dishes in the sink have finished washing and rinse aid needs to be added, the driver 4 can be restarted, causing the output end of the driver 4 to retract again. The first connecting plate 71 and the second connecting plate 51, which are connected in series via the connecting rod 62, move synchronously toward the driver 4, causing the sealing head 52 located at the other end of the sealing assembly 5 to exit from the output through hole 130 on the wall of the rinse aid metering chamber 13. This allows the rinse aid to flow from the rinse aid metering chamber 13 into the discharge channel 111. The rinse aid then passes through the discharge hole of the rinse aid panel 2 and enters the sink, thus completing the rinse aid addition.

[0054] The powder and liquid dispensing dispenser of this utility model, through the cooperation of the swing plate 6, the second connecting plate 51, the first connecting plate 71 and the driver 4, can change the connecting rod 62 of the swing plate 6 from a first state where it is inserted into the second through hole 710 but not into the first through hole 510, to a second state where the end of the connecting rod 62 passes through the second through hole 710 and extends into the first through hole 510. Thus, the driver 4 can open the powder box 3 through the cooperation of the swing plate 6 and the first connecting plate 71 in the first state, and can dispensing the brightener through the cooperation of the swing plate 6, the second connecting plate 51 and the first connecting plate 71 in the second state, thus achieving the purpose of step-by-step control of powder and liquid dispensing.

[0055] Specifically, the swing plate 6 is provided with a starting station, a powder feeding station, a waiting station and a liquid feeding station;

[0056] When the output end of the driver 4 is in the extended state, the end of the connecting rod 62 passes through the second through hole 710 and abuts against the second connecting plate 51, defining the swing plate 6 as being in the starting position at this time;

[0057] When the output end of the driver 4 retracts, it pulls the first connecting plate 71 and drives the swing plate 6 to rotate through the connecting rod 62. The first connecting plate 71 drives the meshing part 72 and the opening assembly 8 to rotate synchronously, so as to open the powder box 3 and complete the dispensing of dishwashing powder. At the same time, the connecting rod 62, which passes through the second through hole 710, extends into the first through hole 510, defining the swing plate 6 at this time as being located at the powder dispensing station.

[0058] The output end of the driver 4 located at the powder feeding station stops retracting and extends, pushing the first connecting plate 71 to drive the meshing part 72 and the cover opening assembly 8 to rotate synchronously in opposite directions. When the outer peripheral surface of the connecting rod 62 abuts against the inner wall of the second through hole 710 near the driver 4, the driver 4 stops, and the swing plate 6 is defined as being in the waiting station at this time.

[0059] The output end of the driver 4, which is located in the waiting position, retracts again and pulls the first connecting plate 71 and the second connecting plate 51 to move synchronously toward the driver 4 through the swing plate 6, so that the sealing head 52 located at the other end of the sealing assembly 5 exits from the output through hole 130 of the tank wall of the finishing agent metering chamber 13 and completes the addition of the finishing agent. At this time, the swing plate 6 is defined as being located in the liquid addition position.

[0060] Figure 5 This is a schematic diagram of the rear structure of an embodiment of the dispenser for step-by-step control of powder and liquid feeding according to the present invention, located at the starting position. Figure 6 This is a schematic diagram of the rear structure of an embodiment of the distributor of the present invention, which allows for step-by-step control of powder and liquid feeding, located at the powder feeding station. Figure 7 This is a schematic diagram of the rear structure of an embodiment of the dispenser for step-by-step control of powder and liquid dispensing according to the present invention, located at the waiting station. Figure 8 This is a schematic diagram of the back structure of an embodiment of the dispenser for step-by-step control of powder and liquid dispensing according to the present invention, located at the liquid dispensing station.

[0061] like Figures 5-8 As shown, by controlling the movement of the driver 4, the oscillating plate 6 of the dispenser passes through the starting station, powder dispensing station, waiting station and liquid dispensing station in sequence, and completes one dispensing of dishwashing powder and rinse aid.

[0062] Afterwards, the user flips down and pulls open the dishwasher door. The dispenser located inside the door changes from an upright state to a horizontal state. At this time, the swing plate 6 sinks down, and the end of the connecting rod 62 leaves the first through hole 510. At the same time, the rinse aid flows from the rinse aid storage chamber 11 into the rinse aid metering chamber 13 through the delivery channel 112. After the user takes out the cleaned dishes, he moves the lever 31 on the surface of the powder box 3 to slide the cover 32 covering the bottom box 33 and open the bottom box 33. Then, he adds dishwasher powder to the bottom box 33 and then pulls the cover 32 in the opposite direction to reset the cover 32 and close the bottom box 33. At this time, the transmission rod 7 returns to the starting position. Then, the user flips up and closes the dishwasher door. The swing plate 6 stands upright with the door and returns to the starting position.

[0063] Preferably, the swing plate 6 is wider at the top and narrower at the bottom, and the center of gravity of the swing plate 6 is located on the side of the connecting rod 62 facing the driver 4;

[0064] The suspension through hole 61 is located at the corner of the top of the swing plate 6, away from the driver 4.

[0065] like Figure 1 and Figure 5 As shown, the center of gravity of the swing plate 6 configured in this way has an eccentric characteristic. The lower end of the swing plate 6 located at the starting position can be biased away from the driver 4 by the gravity of the swing plate 6 itself, thereby preventing the end of the connecting rod 62 from being inserted into the first through hole 510 at the starting position during operation.

[0066] Preferably, the surface of the first connecting plate 71 abuts against the surface of the second connecting plate 51;

[0067] The surface of the second connecting plate 51 covers the second through hole 710.

[0068] like Figure 1 and Figures 5-8 As shown, the surface of the first connecting plate 71 abuts against the surface of the second connecting plate 51, and the surface of the second connecting plate 51 covers the second through hole 710. This arrangement can prevent the existence of gaps other than the first through hole 510 in the second through hole 710, thereby preventing the connecting rod 62 from being unable to be inserted into the first through hole 510 during the process of moving from the starting station to the powder feeding station.

[0069] Furthermore, the chassis 1 has a rotating shaft 14 on its back; the transmission rod 7 has a rotating part 74.

[0070] The rotating part 74 is located between the first connecting plate 71 and the engaging part 72; the rotating part 74 is rotatably fitted onto the rotating shaft 14.

[0071] Figure 1 , Figure 2 and Figure 4 In the embodiment shown, the rotating opening assembly 8 can pull the lever 31 through the torsion spring assembly 9, causing the cover 32 covering the bottom box 33 to slide upward, thereby opening the bottom box 33.

[0072] like Figure 1 , Figure 2 , Figure 4 and Figure 5-8 As shown, the movable first connecting plate 71 can drive the meshing part 72 to rotate through the rotating part 74, so that the transmission rod 7 can drive the opening assembly 8 and the torsion spring assembly 9 to rotate synchronously through the meshing part 72, and pull the lever 31 to open the opening of the bottom box 33, so that the dishwashing powder in the bottom box 33 can be flushed into the dishwashing basin by the spray arm water.

[0073] Furthermore, it also includes a tension spring 21;

[0074] The chassis 1 is also provided with a fixed shaft 15 on its back; the transmission rod 7 is also provided with a fixing part 73;

[0075] The fixing part 73 and the rotating part 74 are spaced apart, with the fixing part 73 located between the first connecting plate 71 and the rotating part 74; one end of the tension spring 21 is fixed to the fixing shaft 15, and the other end of the tension spring 21 is fixed to the fixing part 73.

[0076] like Figure 1 and Figures 5-8 As shown, the elastic force of the tension spring 21 makes the moving transmission rod 7 more stable when driving the meshing part 72 to rotate, so that there will be no shaking or loosening from the rotating shaft 14.

[0077] Furthermore, a suspension shaft 16 is also provided on the back of the chassis 1;

[0078] The suspension shaft 16 is located between the driver 4 and the sealing assembly 5, and above the driver 4 and the sealing assembly 5;

[0079] The swing plate 6 is suspended from the suspension shaft 16 through the suspension through hole 61.

[0080] like Figure 5 and Figure 6 As shown, this arrangement allows the swing plate 6 to occupy less space between the driver 4 and the sealing assembly 5, making the dispenser more compact.

[0081] In summary, such as Figures 1-3In the embodiment of this utility model shown, the dispenser that allows for step-by-step control of powder and liquid dispensing can, through the cooperation of the swing plate 6, the second connecting plate 51, the first connecting plate 71, and the driver 4, change the connecting rod 62 of the swing plate 6 from a first state where it is inserted into the second through hole 710 but not into the first through hole 510, to a second state where the end of the connecting rod 62 passes through the second through hole 710 and extends into the first through hole 510. Thus, the dispensing of dishwashing powder is completed through the cooperation of the swing plate 6 and the first connecting plate 71 in the first state, and the dispensing of rinse aid is completed through the cooperation of the swing plate 6, the second connecting plate 51, and the first connecting plate 71 in the second state, thereby achieving step-by-step control of powder and liquid dispensing.

[0082] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
