A preferred embodiment of a detergent dispenser for dosing detergent into a washing device, in particular a dishwasher, according to the present disclosure is described in detail below with reference to fig. 1 to 9. The detergent dispenser may dispense a predetermined dose of liquid detergent into a washing chamber of a washing apparatus, in particular may dispense two detergents, for example dishwashing liquid and dishwashing agent, into the washing chamber separately. For example, the detergent dispenser may store a plurality of doses of detergent, and a certain amount of detergent may be dispensed when necessary. In other embodiments, the detergent dispenser may be adapted to dispense detergent into two adjacent washing compartments at different time periods, e.g. the same detergent or different detergents. The detergent dispenser of the present disclosure may also be used in washing apparatuses other than dishwashers, such as washing machines and the like.

As shown in fig. 1, the detergent dispenser 100 may be provided on a sidewall of a washing compartment 201 of a washing appliance 200, such as a sink dishwasher. In the built-in dishwasher, the detergent dispenser may be disposed inside the door panel.

As shown in fig. 2a to 2b, the detergent dispenser comprises a housing 1, on which a first filling opening 11 and a second filling opening 12 are provided, as well as a first dosing opening 13 and a second dosing opening 14 communicating with the washing chamber of the washing apparatus. For example, the filling opening and the feeding opening of the detergent dispenser can be both communicated with the washing chamber, a user can add detergent into the detergent dispenser through the filling opening, and the detergent dispenser quantitatively feeds detergent into the washing chamber through the feeding opening. For example, the filling opening and the feeding opening can be both positioned inside the washing chamber, so that the pollution to the table top of the dishwasher when a user adds detergent can be avoided. The detergent dispenser of the present disclosure may also include only one fill port. In the case where the detergent dispenser is used to dispense two kinds of detergents, a user adds a first detergent, such as dishwashing liquid, etc., from the first filling port 11, and adds a second detergent, such as a dish-brightening agent, etc., different from the first detergent, from the second filling port 12. Further, the first detergent added from the first filling port 11 is transferred to the washing chamber through the first input port 13, and the second detergent added from the second filling port 12 is transferred to the washing chamber through the second input port 14.

As shown in fig. 2a to 2b, the housing 1 may include a first housing 15 and a second housing 16. For example, the first housing 15 and the second housing 16 are connected to each other by at least one of: welding, bonding, snap-fit connection, threaded connection, and the like. Furthermore, the housing 1 may also comprise a plurality of sealing rings (not shown in the figures). When the detergent dispenser is mounted on the side wall of the washing chamber of a dishwasher as shown in fig. 1, a plurality of sealing rings are sandwiched between the side wall of the dishwasher (or rather the outer surface of the side wall) and the detergent dispenser, thereby achieving sealing of the first and second filling openings and the first and second dosing openings, respectively. For example, as shown in fig. 2a, the first and second filling ports 11 and 12 and the first and second input ports 13 and 14 are provided on the first casing 15.

Further, as shown in fig. 4a and 4b, the detergent dispenser further includes a driving part 2, a liquid adding part 3, a storage part 4, a first dispensing part 5, and a second dispensing part 6 provided in the housing 1. For example, as shown in fig. 4b, the liquid adding portion 3, the storage portion 4, the first dispensing portion 5, and the second dispensing portion 6 are provided in the first housing 15. Furthermore, as shown in fig. 4a, the housing 1 may further comprise a cover plate (not shown in the figures) which may be welded, glued, snapped or screwed to the first housing 15 for enclosing parts of the drive part within the housing.

As shown in fig. 4a, the driving portion 2 includes a first output wheel 21 and a second output wheel 22, and is configured to be able to simultaneously drive the first output wheel 21 and the second output wheel 22 to rotate in a first direction and to rotate in a second direction opposite to the first direction. The first direction is clockwise in fig. 4a, and the second direction is counterclockwise in fig. 4 a. The first output wheel 21 and the second output wheel 22 shown in fig. 4a are in their first end positions, respectively. The first output wheel 21 and the second output wheel 22 may also have respective initial positions and respective second end positions. In the initial position, the outer teeth of the first output wheel 21 and the second output wheel 22 are substantially symmetrical with respect to the horizontal dashed line in fig. 4 a. In the second end position, the first output wheel 21 rotates counterclockwise to the top in fig. 4a and the second output wheel 22 rotates counterclockwise to the bottom in fig. 4 a.

The driving part 2 further includes a motor 23 for providing power, and a first gear assembly and a second gear assembly provided at both sides of the worm 24 of the motor and engaged therewith. The first gear assembly comprises only the first gear 25 and it meshes with the first output wheel 21. The second gear assembly includes second gears 26 and 27, and the second gear 27 is meshed with the second output gear 22. Through setting up the worm, motor 23 can the auto-lock, and when the motor outage, the position of drive mechanism (i.e. gear assembly) and executive (i.e. output wheel) is stable unchangeable. In other embodiments, the first gear assembly may include a plurality of gears and the second gear assembly may include only one gear, depending on the particular application. The driving part is integrated in the shell, so that the detergent dispenser is compact in structure, small in size and low in cost.

For example, when the motor 23 rotates in the forward direction, the worm 24 can drive the first gear 25 to rotate counterclockwise, the first gear 25 in turn drives the first output wheel 21 engaged therewith to rotate clockwise, and simultaneously the worm 24 can also drive the second gear 26 to rotate clockwise, the second gear 26 in turn drives the second output wheel 22 to rotate clockwise through the second gear 27 engaged therewith. In this way it is achieved that the first output wheel 21 and the second output wheel rotate simultaneously in the first direction. For example, when the motor 23 is reversed, the worm 24 may drive the first gear 25 to rotate clockwise, the first gear 25 in turn driving the first output wheel 21 engaged therewith to rotate counterclockwise, while the worm 24 may also drive the second gear 26 to rotate counterclockwise, the second gear 26 in turn driving the second output wheel 22 to rotate counterclockwise through the second gear 27 engaged therewith. In this way it is achieved that the first output wheel 21 and the second output 22 rotate simultaneously in the second direction.

The liquid adding part 3 is configured to be able to open a liquid adding port and deliver detergent, i.e., detergent added by a user through the opened liquid adding port flows into the detergent dispenser through the liquid adding part 3. As shown in fig. 4b, in the case where the detergent includes different first and second detergents, the liquid adding part 3 may include a first liquid adding part 31 and a second liquid adding part 32, the first liquid adding part 31 being capable of opening the first liquid adding port 11 and delivering the first detergent, and the second liquid adding part 32 being capable of opening the second liquid adding port 12 and delivering the second detergent.

The first liquid adding portion 31 and the second liquid adding portion 32 may have the same structure. For example, as shown in fig. 3, the first liquid adding part 31 may include a cover body 311, a guide groove 312, a liquid adding float 313, a liquid adding seal 314, and a liquid adding elastic member 315. The cover 311 is provided with a groove 316 for mounting the charging seal 314 and a mounting shaft 317 for mounting the guide groove 312. The guide groove 312 is pivotably connected to the cover 311 and the first housing 15 for connecting the cover 311 and the first housing 15 such that the cover 311 can rotate relative to the first housing 15 and seal the first housing 15. In addition, the guide grooves 312 serve as a guide structure of the detergent. The charge seal 314 is used to seal the first charge port. Further, a charging float groove 318 for attaching the charging float 313 is provided on the cover body 311. A dosing float 313 is slidably connected to the draft trough 312 for alerting the user to the maximum level of detergent to be added. The liquid feeding elastic member 315 is connected between the guiding groove 312 and the first housing 15, and is used for realizing the bidirectional positioning of the opening and closing of the cover 311. By providing the liquid addition portion, the liquid addition port can be opened and closed. When the corresponding filling opening is opened through the cover body 311, the user may add detergent, which in turn flows into the detergent dispenser through the guide groove 312.

The storage part 4 is configured to communicate with the liquid adding part 3 and store the detergent delivered from the liquid adding part 3. As shown in fig. 4b, the storage part 4 includes a first storage chamber 41 and a second storage chamber 42, the first storage chamber 41 communicating with the first liquid adding part 31 and storing a first detergent, and the second storage chamber 42 communicating with the second liquid adding part 32 and storing a second detergent. The first storage chamber 41 and the second storage chamber 42 are formed by joining the first case 15 and the second case 16 and are independent of each other. The guide grooves of the first and second liquid adding portions 31 and 32 are directly communicated to the first and second storage chambers 41 and 42, respectively, and guide the first detergent into the first storage chamber 41 and the second detergent into the second storage chamber 42. In other words, the first filling port 11 communicates with the first storage chamber 41, and the second filling port 12 communicates with the second storage chamber 42. Of course, in some embodiments, the channels may also communicate indirectly with the respective storage chambers through additional components.

Referring to fig. 4b, the first launch part 5 comprises a first cavity 50 (also referred to as a metering cavity) and a first valve body assembly located within the first cavity and drivable by the first output wheel 21, and the second launch part 6 comprises a second cavity 60 and a second valve body assembly located within the second cavity and drivable by the second output wheel 22. The first chamber body 50 includes a first liquid inlet 501 communicating with the first storage chamber 41 and a first liquid outlet 502 communicating with the first discharge port 13 (see fig. 8). The second chamber 60 comprises a second liquid inlet 601 communicating with the second reservoir 42 and a second liquid outlet 602 communicating with the second dosing port 14 (as shown in fig. 8). The first chamber 50 is located below the first storage chamber 41 so that the first detergent can be delivered from the first storage chamber to the first chamber by its own weight. For the same reason, the second chamber 60 is also located below the second storage chamber 42. When the first output wheel 21 and the second output wheel 22 described above are rotated in the first direction (i.e., clockwise) from the respective initial positions to the respective first end positions, the first valve body assembly opens only the first liquid outlet port 502, and the second valve body assembly opens only the second liquid inlet port 601. When the first output wheel 21 and the second output wheel 22 rotate in the second direction (i.e., counterclockwise direction) from the respective initial positions to the respective second end positions, the first valve body assembly opens only the first inlet port 501, and the second valve body assembly opens only the second outlet port 602. In this way, a sequential dosing of the first detergent and the second detergent and a sequential injection in the respective dosing chamber can be achieved. That is, different detergents may be injected into the metering chamber at different time periods, or different detergents may be dosed into the washing chamber at different time periods.

As shown in fig. 4b, the first and second launch portions 5, 6 have substantially the same structure and are arranged mirror-symmetrically with respect to each other within a housing, for example a first housing 15. For example, the first and second cavities 50 and 60 may have the same and symmetrical structure. For example, as shown in fig. 4b and fig. 7 to 9, the first valve body assembly and the second valve body assembly have the same structure and are disposed within the housing in mirror image with respect to each other, for example, symmetrically with respect to the partition a of the first housing 15 for partitioning the first storage chamber 41 and the second storage chamber 42, within the first housing 15.

For example, the first valve body assembly includes a first valve body 51, a second valve body 52, and an elastic member 53, and the second valve body assembly includes a first valve body 51 ', a second valve body 52 ', and an elastic member 53 '. The elastic member 53 of the first valve body assembly is configured to exert an elastic biasing force on the first valve body 51 and the second valve body 52 of the first valve body assembly, respectively, so that the first valve body 51 closes the first liquid inlet port 501 and the second valve body 52 closes the first liquid outlet port 502. The first valve body 51 of the first valve body assembly is configured to be able to open the first liquid inlet port 501 against the elastic biasing force applied thereto under the drive of the first output wheel 21. The second valve body 52 of the first valve body assembly is configured to be able to open the first liquid outlet port 502 against the elastic biasing force applied thereto under the driving of the first output wheel 21. The elastic member 53 ' of the second valve body assembly is configured to exert elastic biasing force on the first valve body 51 ' and the second valve body 52 ' of the second valve body assembly, respectively, so that the first valve body 51 ' closes the second inlet port 601 and the second valve body 52 ' closes the second outlet port 602. The first valve body 51' of the second valve body assembly is configured to be capable of opening the second loading port 601 against a resilient biasing force applied thereto under the drive of the second output wheel 22. The second valve body 52' of the second valve body assembly is configured to be capable of opening the second liquid outlet 602 against a resilient biasing force applied thereto under the drive of the second output wheel 22.

Further, for example, the first and second valve bodies 51 and 52 of the first valve body assembly and the first and second valve bodies 51 'and 52' of the second valve body assembly may have the same structure. As shown in fig. 4b, the first inlet port 501 and the first outlet port 502 are symmetrically disposed on the first cavity 50, and the second inlet port 601 and the second outlet port 602 are symmetrically disposed on the second cavity 60.

In other embodiments, the first valve body 51 and the second valve body 52 of the first valve body assembly have the same structure, the first valve body 51 ' and the second valve body 52 ' of the second valve body assembly have the same structure, and the structure of the first valve body 51 of the first valve body assembly is different from the structure of the first valve body 51 ' of the second valve body assembly.

For example, the first output wheel 21 shown in fig. 5a may include a first output shaft 210 integrally formed therewith, the first and second valve bodies 51, 52 of the first valve body assembly being connected to and directly driven by the first output shaft 210. For example, the second output wheel 22 shown in fig. 5b may also include a second output shaft 220 integrally formed therewith, with the first and second valve bodies 51 ', 52' of the second valve body assembly being connected to and directly driven by the second output shaft 220. The first output shaft 210 and the second output shaft 220 have respective axes of rotation (the axis of rotation of the first output shaft 210 is shown by the dashed straight line in fig. 5 a) and can rotate reversibly, i.e. can rotate in forward direction and can be rotationally reset in reverse, following the respective output wheels. The first valve body 51 and the second valve body 52 of the first valve body assembly are able to rotate about their rotational axes when the first output shaft 210 rotates. The first valve body 51 'and the second valve body 52' of the second valve body assembly are able to rotate about their rotational axes when the second output shaft 220 rotates.

Fig. 6a and 6b show schematic configurations of a first valve body 51 'and a second valve body 52' of a second valve body assembly, which are identical. The first valve body 51 'includes a rotation shaft 511' provided on a main body thereof and having a through hole, and the second valve body 52 'includes a rotation shaft 521' provided on a main body thereof and having a through hole. That is, the rotating shafts are each hollow, for example, having a cylindrical shape. When the detergent dispenser is assembled, the first output shaft 210 is inserted into the through holes of the rotating shafts of the first and second valve bodies 51 and 52 of the first and second valve body assemblies, and the second output shaft 220 is inserted into the through holes of the rotating shafts 511 ', 521' of the first and second valve bodies 51 'and 52' of the second valve body assembly. The shape of the output shaft is matched with the through hole of the rotating shaft of the associated valve body. Further, the first valve body 51 'includes a first sealing portion 512' provided on the body thereof for sealing the corresponding liquid inlet, and the second valve body 52 'includes a second sealing portion 522' provided on the body thereof for sealing the corresponding liquid outlet. For example, the first seal 512 'is integrally formed with the body of the associated first valve body 51'. For example, the second seal 522 'is integrally formed with the body of the associated second valve body 52'. Further, the first valve body and the second valve body further comprise mounting portions which are arranged on the respective main bodies and used for mounting the corresponding elastic pieces. For example, as shown in fig. 4b, the resilient member is disposed between an end of the associated first sealing portion remote from the respective liquid inlet port and an end of the associated second sealing portion remote from the respective liquid outlet port. For example, the elastic member 53 ' is disposed between an end of the first sealing portion 512 ' of the first valve body 51 ' of the second valve body assembly away from the second inlet port 601 and an end of the second sealing portion 522 ' of the second valve body 52 ' away from the second outlet port 602. The elastic piece directly exerts the effort to the sealing part and makes the sealed effect better. The first valve body 51 and the second valve body 52 of the first valve body assembly may have the same or similar structure as the first valve body 51 'and the second valve body 52' of the second valve body assembly, that is, a rotating shaft disposed on the main body and having a through hole and a sealing portion for sealing the corresponding liquid inlet and the liquid outlet, which are not described herein again.

For driving the first valve body 51 and the second valve body 52 of the first valve body assembly, the first output shaft 210 is provided with a first driving surface 211 and a second driving surface 212, the first valve body 51 of the first valve body assembly is provided with a first driven surface 514 which is matched with the first driving surface 211, and the second valve body 52 is provided with a second driven surface 524 which is matched with the second driving surface 212. Similarly, in order to drive the first valve body 51 'and the second valve body 52' of the second valve body assembly, the second output shaft 220 is provided with a first driving surface 221 and a second driving surface 222, the first valve body 51 'of the second valve body assembly is provided with a first driven surface 514' matched with the first driving surface 221, and the second valve body 52 'is provided with a second driven surface 524' matched with the second driving surface 222.

As shown in fig. 5a, the first driving surface 211 and the second driving surface 212 of the first output shaft 210 are provided on the outer circumferential surface of the first output shaft 210. As shown in fig. 5b, the first driving surface 221 and the second driving surface 222 of the second output shaft 220 are provided on the outer circumferential surface of the second output shaft 220. As shown in fig. 5a, the first output shaft 210 is provided with a groove extending along the rotation axis, and both side surfaces of the groove form a first driving surface 211 and a second driving surface 212, respectively. The second output shaft 220 has the same structure. As shown in fig. 6a to 9, the first driven surface 514, 514 'of the first valve body 51, 51' is provided on an inner surface of the through hole of the rotating shaft thereof, for example, a surface of the first projection on the inner surface of the through hole, which faces the first driving surface of the corresponding output shaft. As shown in fig. 6a to 9, the second driven surface 524, 524 'of the second valve body 52, 52' is provided on an inner surface of the through hole of the rotary shaft thereof, for example, a surface of the second projection on the inner surface of the through hole facing the second driving surface of the corresponding output shaft. The protrusions protrude from the inner circumferential surface of the corresponding rotary shaft toward the rotary shaft center or the rotation axis.

The output shaft not only serves as a driving piece but also serves as a rotation center limiting piece of the valve body, so that the output shaft and the valve body are more accurately matched and are not easy to slip.

To avoid affecting the gland seal effect and cavity size, it is ensured that the diameter profile of the output shaft is not too large. In this case, the use of a groove for driving makes the material removed relatively small, having a small influence on the structural strength of the output shaft. The reason for providing the cylindrical rotating shaft on the valve body is that the uniform wall thickness is favorable for the injection molding precision, so that the protrusions on the inner circumferential surface only need to be increased in thickness compared with most of the wall thickness, which has less influence on the material molding and more stable structure of the valve body.

Fig. 7 to 9 show schematic views of a first valve body assembly in the first chamber 50 and a second valve body assembly in the second chamber 60 in different states, and the lower respective views in fig. 7 to 9 are enlarged partial schematic views of the upper views, which show the engagement of the output shaft with the respective valve body assemblies. The first valve body 51, the second valve body 52 'in fig. 7 to 9 are indicated with black solid patterns to distinguish from the second valve body 52, the first valve body 51'. Fig. 8 shows a state in which both the liquid inlet ports 501 and 601 and the liquid outlet ports 502 and 602 of the first and second injection portions are closed. Fig. 7 shows a first state in which the first inlet port 501 of the first cavity of the first input portion is closed, the first outlet port 502 is opened, the second inlet port 601 of the second cavity of the second input portion is opened, and the second outlet port 602 is closed. Fig. 9 shows a second state in which the first inlet port 501 of the first cavity of the first input portion is open, the first outlet port 502 is closed, the second inlet port 601 of the second cavity of the second input portion is closed, and the second outlet port 602 is open.

When the first and second output wheels 21 and 22 rotate in the first direction from their respective initial positions to their respective first end positions (as shown in fig. 4 a), the first and second throws are as shown in fig. 8 to 7, the second drive surface 212 of the first output shaft 210 contacts the second driven surface 524 of the second valve body 52 of the first valve body assembly and drives the second valve body 52 of the first valve body assembly to rotate in the first direction (i.e., clockwise in the figure) to open the first liquid outlet port 502, and the first drive surface 221 of the second output shaft 220 contacts the first driven surface 514 ' of the first valve body 51 ' of the second valve body assembly and drives the first valve body 51 ' of the second valve body assembly to rotate in the first direction to open the second liquid inlet port 601. When the first and second cavities are initially empty, the second detergent may flow into the second cavity 60 in the first state shown in fig. 7. By setting the motor, the output shaft may be caused to remain in the first state shown in fig. 7 for a period of time (i.e., the first and second output wheels remain in the respective first end positions), whereby a predetermined dose of the second detergent may be delivered into the second chamber 60.

Of course, the first and second launch portions may also implement the process of fig. 7 to 8, in which process, the motor is reversed and the first and second output wheels are rotated in a second direction (i.e., counterclockwise in the figures) from their respective first end positions to their respective initial positions, the second drive surface 212 of the first output shaft 210 no longer contacts the second driven surface 524 of the second valve body 52 of the first valve body assembly, the first drive surface 221 of the second output shaft 220 no longer contacts the first driven surface 514 'of the first valve body 51' of the second valve body assembly, accordingly, the second valve body 52 of the first valve body assembly is rotated in the second direction to close the first liquid outlet port 502 by the elastic biasing force of the associated elastic member 53, and the first valve body 51 'of the second valve body assembly is rotated in the second direction to close the second liquid inlet port 601 by the elastic biasing force of the associated elastic member 53'.

When the first output wheel 21 and the second output wheel 22 rotate in the second direction from the respective initial positions to the respective second end positions (not shown in the drawings), the first throw portion and the second throw portion are as shown in fig. 8 to 9, the first driving surface 211 of the first output shaft 210 contacts the first driven surface 514 of the first valve body 51 of the first valve body assembly and drives the first valve body 51 of the first valve body assembly to rotate in the second direction to open the first inlet port 501, and the second driving surface 222 of the second output shaft 220 contacts the second driven surface 524 ' of the second valve body 52 ' of the second valve body assembly and drives the second valve body 52 ' of the second valve body assembly to rotate in the second direction to open the second outlet port 602. When the first and second cavities are initially empty, the first detergent may flow into the first cavity 50 in the second state shown in fig. 9. By setting the motor, the output shaft can be caused to remain in the second state shown in fig. 9 for a period of time (i.e. the first and second output wheels remain in the respective second end positions), whereby a predetermined dose of the first detergent can be delivered into the first cavity 50.

Of course, the first and second throws may also implement the process of fig. 9 to 8, in which the motor rotates forward, the first and second output wheels 21 and 22 rotate in the first direction from the respective second end positions to the respective initial positions, the first driving surface 211 of the first output shaft 210 no longer contacts the first driven surface 514 of the first valve body 51 of the first valve body assembly, the second driving surface 222 of the second output shaft 220 no longer contacts the second driven surface 524 'of the second valve body 52' of the second valve body assembly, and therefore, the first valve body 51 of the first valve body assembly rotates in the first direction to close the first inlet port 501 under the elastic biasing force of the associated elastic member 53, and the second valve body 52 'of the second valve body assembly rotates in the first direction to close the second outlet port 602 under the elastic biasing force of the associated elastic member 53'.

By utilizing the characteristic of positive and negative rotation of the motor, the processes can be carried out in a circulating and reciprocating manner, and intermittent and orderly feeding of different detergents stored in the two independent storage cavities is realized. In addition, two output wheels are driven to rotate simultaneously through one electrode, so that the number of parts is reduced, and the processing and manufacturing difficulty and cost are reduced.

The same elastic piece is used for resetting the two valve bodies, so that the cost can be reduced. In addition, the liquid inlet and the liquid outlet can be closed by the elastic force of the elastic piece, the sealing performance in a long-time closing state can be ensured, the sealing device is stable and reliable, extra power is not needed, and energy is saved.

Furthermore, the liquid inlet and the liquid outlet which are arranged in the same metering cavity are not opened at the same time, so that the metering cavity is prevented from being leaked when liquid is fed, no residue is generated when liquid is discharged, and the accuracy of the detergent feeding amount is ensured.

In addition, the technical features disclosed in the above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the disclosure purpose, so as to achieve the purpose of the disclosure.
