Description

Technical Field

[0001] The present application relates to the field of detergent dispensing, and in particular to a detergent dispensing device and a washing machine. Background Art

[0002] In the related art, washing equipment often needs to add detergent during the washing process. Taking washing machines as an example, detergents such as laundry detergent and softener need to be added. Since manual addition of detergents requires additional operations and the amount and timing of addition are difficult to accurately grasp, washing machines with automatic addition functions are becoming more and more popular. Most of the related automatic addition devices use electric-driven peristaltic pumps, gear pumps, piston pumps and other pump bodies to extract detergents to achieve automatic addition. In this way, an additional electric-driven pump body needs to be set up, which increases the hardware cost and makes it difficult to widely promote and apply washing machines with automatic addition functions.

[0081] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present application. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0082] In the description of the present application, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0083] In the description of the present application, the terms "first, second" and the like are only used to distinguish similar objects and do not represent a specific order of the objects. It is understandable that "first, second" and the like can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. Unless otherwise specified, "plurality" means at least two.

[0084] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0085] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0086] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0087] The present application provides a detergent dispensing device, which can use water flow as a power source to achieve automatic detergent dispensing. Figures 1 to 9As shown, the detergent dispensing device comprises: a first chamber 1A, a second chamber 1C, a rotating mechanism 2, a speed reduction mechanism 3, a power distribution mechanism 4 and a dispensing mechanism. Among them, the first chamber 1A has a first water inlet 1011 and a second water inlet 1012, and the second chamber 1C has a first liquid inlet 1016 and a second liquid inlet 1018. The rotating mechanism 2 is arranged in the first chamber 1A. The speed reduction mechanism 3 is connected to the rotating mechanism 2, and is used to reduce the power output by the rotating mechanism 2 and increase the torque before output. The power distribution mechanism 4 is connected to the output end of the speed reduction mechanism 3, and the power distribution mechanism 4 has a first output end and a second output end for transmitting the power output by the speed reduction mechanism 3. The dispensing mechanism comprises a first dispensing mechanism 5 and a second dispensing mechanism 6, the first dispensing mechanism 5 is connected to the first output end, and is used to control the dispensing of detergent at the first liquid inlet 1016; the second dispensing mechanism 6 is connected to the second output end, and is used to control the dispensing of detergent at the second liquid inlet 1018.

[0088] Since the rotating mechanism 2 can be driven by the water flow flowing into the first chamber 1A through the first water inlet 1011 or the second water inlet 1012, the power output by the rotating mechanism 2 is output to the power distribution mechanism 4 after being decelerated and torque-increased by the speed reduction mechanism 3, and the power distribution mechanism 4 drives the first distribution mechanism 5 to control the delivery of detergent at the first liquid inlet 1016 or drives the second distribution mechanism 6 to control the delivery of detergent at the second liquid inlet 1018. In this way, the detergent delivery device can use the water flow as a power source to realize automatic delivery of detergent, and the electric drive device can be omitted, thereby saving costs. Here, the detergent can be a liquid or powdered washing product required for washing, and those skilled in the art can make a reasonable choice according to needs, and this application does not make specific restrictions on this.

[0089] In addition, it should be noted that since the water pressure of the water flow may fluctuate during use, in the embodiment of the present application, the output power of the rotating mechanism 2 is transmitted to the power distribution mechanism 4 after being decelerated and torque-increased by the speed reduction mechanism 3, which can effectively widen the working range of the water flow water pressure, so that after the water flow in the low water pressure state drives the rotating mechanism 2, the speed reduction mechanism 3 decelerates and increases the torque, thereby increasing the torque output by the power distribution mechanism 4, so that the first dispensing mechanism 5 or the second dispensing mechanism 6 can effectively control the delivery of detergent at their respective liquid inlets, thereby realizing automatic delivery of detergent, and since the first dispensing mechanism 5 controls the delivery of detergent at the first liquid inlet 1016 and the second dispensing mechanism 6 controls the delivery of detergent at the second liquid inlet, different types of detergents can be automatically delivered according to classification, thereby further saving the control cost of automatic delivery according to classification.

[0090] For example, Figure 1 and Figure 2As shown, the detergent dispensing device comprises: a housing 1, in which a first chamber 1A and a second chamber 1C are formed which are spaced apart from each other. A first water inlet 1011 and a second water inlet 1012 are located on a first side of the housing 1, and a water outlet 1013 is located on a second side of the housing 1. If water flows in from the first water inlet 1011 and flows out from the water outlet 1013, the rotating mechanism 2 is driven to rotate in a first direction; if water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the rotating mechanism 2 is driven to rotate in a second direction.

[0091] Exemplarily, the first water inlet 1011 and the second water inlet 1012 are located on the first side of the housing 1 (i.e. Figure 2 The water outlet 1013 is located on the second side of the housing 1 opposite to the first side (i.e. Figure 2 if water flows in from the first water inlet 1011 and flows out from the water outlet 1013, the driving mechanism 2 is rotated in a first direction (eg Figure 2 If water flows in from the second water inlet 1012 and flows out from the water outlet 1013, the driving mechanism 2 rotates in the second direction (eg Figure 2 It can be understood that if water flows into the first water inlet 1011 and the second water inlet 1012 at the same time with similar flow rates, the power of the rotating mechanism 2 cancels each other out, that is, it can maintain a stationary state, but the water can flow out normally from the water outlet 1013. In this way, by controlling the water supply state of the first water inlet 1011 and the second water inlet 1012, the clockwise rotation, counterclockwise rotation and stationary state of the rotating mechanism 2 can be switched under the condition of normal water supply to the first chamber 1A. In actual applications, the first water inlet 1011 and the second water inlet 1012 can be connected to the water supply waterway via an electromagnetic valve, and the water supply state of the first water inlet 1011 and the second water inlet 1012 is controlled by the electromagnetic valve, so that the rotation state of the rotating mechanism 2 can be effectively controlled.

[0092] It is understandable that there can be multiple water outlets 1013 , and those skilled in the art can reasonably set them according to needs, which is not limited here.

[0093] It is understandable that those skilled in the art can reasonably set the position of the water outlet 1013 according to the needs, and no limitation is made here. For example, the side where the water outlet 1013 is located can be perpendicular to or opposite to the side where the first water inlet 1011 and the second water inlet 1012 are located.

[0094] In some embodiments, Figure 2As shown, the first chamber 1A is roughly formed as a cylindrical chamber, and the first side of the first chamber 1A extends outward to form a first water inlet pipe 1020 and a second water inlet pipe 1021. The first water inlet pipe 1020 and the second water inlet pipe 1021 are arranged in parallel and are respectively located at the upper and lower ends of the first chamber 1A, and the second side of the first chamber 1A extends outward to form a water outlet pipe 1022, and the water outlet pipe 1022 is located in the middle of the first chamber 1A.

[0095] Exemplarily, a first water inlet 1011 is formed at the inlet of the first water inlet pipe 1020, a second water inlet 1012 is formed at the inlet of the second water inlet pipe 1021, and a water outlet 1013 is formed at the outlet of the water outlet pipe 1022; when water flows in from the first water inlet 1011, the rotating mechanism 2 is driven to rotate in the first direction; when water flows in from the second water inlet 1012, the rotating mechanism 2 is driven to rotate in the second direction.

[0096] It is understandable that the rotating mechanism 2 can be an impeller driven by water flow, such as a turbine or a propeller. As long as the rotating mechanism 2 can rotate and output power under the action of the water flow passing through the first chamber 1A, this application does not make any specific restrictions on this.

[0097] In some embodiments, Figure 1 and Figure 2 As shown, the rotating mechanism 2 includes an impeller 21, the rotating shaft of the impeller 21 is vertically arranged in the chamber 1A, the first water inlet 1011 and the second water inlet 1012 are located on one side of the impeller 21, and the water outlet 1013 is located on the other side of the impeller 21. After the water flows in through the first water inlet 1011 or the second water inlet 1012, it is suitable for driving the impeller 21 to rotate, and flows out through the water outlet 1013; the rotating shaft of the impeller 21 is connected to the input end of the reduction mechanism 3. In this way, the impeller 21 can rotate under the drive of the water flow, thereby converting the water energy into mechanical energy. Here, the impeller 21 includes a plurality of blades 211 fixed on the output shaft, and the blades 211 can be curved blades or straight blades, wherein the straight blade refers to the surface of the blade being planar, so as to rotate under the drive of the water flow; the curved blade refers to the surface of the blade being curved, so that the end of the blade has a set curvature, which is conducive to the formation of a rotating vortex.

[0098] For example, Figure 1 and Figure 2 As shown, the housing 1 includes a shell 101 and a first end cover 102. The first end cover 102 cooperates with the shell 101 to form a first chamber 1A. The first water inlet 1011 and the second water inlet 1012 are spaced apart. Figure 2 On the left side of the housing 101 shown in FIG. 1 , for example, the first water inlet 1011 and the second water inlet 1012 are spaced apart from each other on the outer side of the housing 101; the water outlet 1013 is arranged at a position such as Figure 2The right side of the housing 101 is shown. For example, the direction of the water flow is along Figure 2 As shown by the arrow, the rotating mechanism 2 located in the first chamber 1A rotates in the clockwise direction or counterclockwise direction under the pressure of the water flow, or stops when the pressure is balanced and maintains normal water supply.

[0099] It can be understood that the reduction mechanism 3 may include but is not limited to: a gear reducer, a worm gear reducer or a planetary reducer, as long as it can convert the power output by the water flow-driven rotating mechanism 2 into a larger output torque, and this application does not make any specific limitations on this.

[0100] For example, Figure 1 and Figure 3 As shown, the speed reduction mechanism 3 includes: a power shaft 301, a first speed reduction gear 302, a second speed reduction gear 303 and an output shaft 304. The first speed reduction gear 302 has a large end face meshing with the power shaft 301 and a small end face for meshing with the second speed reduction gear 303. The power shaft 301 can extend into the first chamber 1A and connect to the rotating mechanism 2, and is driven by the rotating mechanism 2. The power shaft 301 cooperates with the large end face of the first speed reduction gear 302 to achieve speed reduction; the small end face of the first speed reduction gear 302 cooperates with the second speed reduction gear 303 to achieve speed reduction again; the second speed reduction gear 303 is connected to the output shaft 304, so that the power of the water flow can be transmitted to the power distribution mechanism 4 through the output shaft 304 after step-by-step speed reduction. It can be understood that the number of speed reduction gears arranged between the power shaft 301 and the output shaft 304 can be set according to needs to meet the needs of the speed reduction ratio.

[0101] In some embodiments, Figure 4 and Figure 5 As shown, the reduction mechanism 3 includes: a power shaft 301, a planetary gear 305, a planetary carrier 306 and a ring gear 307, wherein the power shaft 301 is connected to the rotating mechanism 2 and driven by the rotating mechanism 2; the ring gear 307 is fixed on the housing 101, and it can be understood that the ring gear 307 can be a separately arranged annular member, and the inner wall of the annular member is provided with internal teeth, and the annular member is fixed in the third chamber 1B, or the ring gear 307 with an annular inner tooth surface is formed on the inner wall of the third chamber 1B; the planetary gear 305 is arranged between the power shaft 301 and the ring gear 307, and is meshed with the power shaft 301 and the ring gear 307; the planetary carrier 306 is connected to the planetary gear 305, and outputs power to the power distribution mechanism 4 under the drive of the planetary gear 305. It can be understood that one end of the power shaft 301 can extend into the first chamber 1A and be fixedly connected to the rotating mechanism 2, and the other end of the power shaft 301 is provided with external teeth meshing with the planetary gear 305, serving as the sun gear of the planetary reducer. The planet carrier 306 has an end for outputting power, which is connected to the input end of the power distribution mechanism 4.

[0102] In some embodiments, the reduction ratio of the speed reduction mechanism 3 is 30 to 150: 1. Thus, the detergent dispensing device can work normally within the water pressure range of 0.03 MPa to 1.0 MPa, so that the detergent dispensing device has a wide range of application prospects, for example, it can be applied to household appliances such as washing machines or dishwashers.

[0103] For example, the aforementioned speed reduction mechanism 3, power distribution mechanism 4 and distribution mechanism may be located in separate chambers. Figure 1 As shown, the distribution mechanism is arranged in the second chamber 1C, and a third chamber 1B accommodating the reduction mechanism 3 and a fourth chamber 1D accommodating the power distribution mechanism 4 are formed in the outer shell 101. The third chamber 1B and the fourth chamber 1D are located between the first chamber 1A and the second chamber 1C.

[0104] It is understandable that at least two of the aforementioned speed reduction mechanism 3, power distribution mechanism 4 and distribution mechanism are located in the same chamber. In some embodiments, the power distribution mechanism 4 can be arranged in the third chamber 1B, that is, the fourth chamber 1D is omitted. The third chamber 1B is located between the first chamber 1A and the second chamber 1C, so that the structure is compact, and the speed reduction mechanism 3 and the power distribution mechanism 4 are both located in the third chamber 1B, so that the detergent dispensing device has a beautiful appearance. In some embodiments, the third chamber 1B and the fourth chamber 1D can be omitted, so that the speed reduction mechanism 3 and the power distribution mechanism 4 are both arranged in the second chamber 1C.

[0105] like Figure 6 As shown, the power distribution mechanism 4 includes: a driving wheel 401, a first ratchet shaft 402, a driven wheel 403 and a second ratchet shaft 404; wherein the driving wheel 401 is connected to the output end of the speed reduction mechanism 3 (such as Figure 3 The output shaft 304 shown or Figure 4The planet carrier 306 shown in the figure, the inner wall surface of the driving wheel 401 is provided with a first ratchet 4011; the first ratchet shaft 402 is sleeved in the driving wheel 401, and can cooperate with the first ratchet 4011 to rotate in one direction; the driven wheel 403 is meshed and connected with the driving wheel 401, and the inner wall surface of the driven wheel 403 is provided with a second ratchet 4031; the second ratchet shaft 404 is sleeved in the driven wheel 403, and can cooperate with the second ratchet 4031 to rotate in one direction. The first ratchet shaft 402 forms the first output end of the power distribution mechanism 4, and the second ratchet shaft 404 forms the second output end of the power distribution mechanism 4. It should be noted that the driving wheel 401 and the driven wheel 403 are meshed with external teeth, and the rotation directions of the two are opposite, and the first ratchet shaft 402 and the second ratchet shaft 404 have the same direction of unidirectional rotation. For example, taking the example that both the first ratchet shaft 402 and the second ratchet shaft 404 rotate unidirectionally clockwise, when the driving wheel 401 rotates clockwise, the first ratchet shaft 402 rotates clockwise under the drive of the first ratchet tooth 4011, the driven wheel 403 rotates counterclockwise, and the second ratchet shaft 404 and the second ratchet tooth 4031 slip and cooperate; when the driving wheel rotates counterclockwise, the first ratchet shaft 402 and the first ratchet tooth 4011 slip and cooperate, the driven wheel 403 rotates clockwise, and the second ratchet shaft 404 rotates clockwise under the drive of the second ratchet tooth 4031.

[0106] It can be understood that the driving wheel 401 is connected to the output end of the speed reduction mechanism 3, that is, connected to Figure 3 The output shaft 304 shown or Figure 4 The end of the planet carrier 306 shown in the figure is so as to rotate under the action of the power transmitted by the reduction mechanism 3. The driving wheel 401 and the first ratchet shaft 402 constitute a first ratchet assembly, and the driven wheel 403 and the second ratchet shaft 404 constitute a second ratchet assembly. Specifically, the outer wall surface of the first ratchet shaft 402 is provided with an elastic pawl cooperating with the first ratchet tooth 4011, and the cooperation between the pawl and the first ratchet tooth 4011 makes the first ratchet shaft 402 only rotate in one direction; similarly, the outer wall surface of the second ratchet shaft 404 is provided with an elastic pawl cooperating with the second ratchet tooth 4031, and the cooperation between the pawl and the second ratchet tooth 4031 makes the second ratchet shaft 404 only rotate in one direction. Since the driving wheel 401 is meshedly connected with the driven wheel 403, for example, meshedly connected by teeth or pins, the rotation directions of the driving wheel 401 and the driven wheel 403 are opposite. Figure 6As shown, the ratchet shaft and the ratchet teeth slip in the counterclockwise direction and rotate in the clockwise direction as an example for explanation. When the driving wheel 401 rotates clockwise under the drive of the speed reduction mechanism 3, the driven wheel 403 rotates counterclockwise. At this time, the first ratchet shaft 402 is pushed by the first ratchet teeth 4011 of the driving wheel 401 and also rotates clockwise, but the second ratchet shaft 404 is in a slipping state because the driven wheel 403 rotates counterclockwise, and does not transmit torque. When the driving wheel 401 rotates counterclockwise under the drive of the speed reduction mechanism 3, the driven wheel 403 rotates clockwise. At this time, the first ratchet shaft 402 is in a slipping state and does not transmit torque, but the second ratchet shaft 404 rotates clockwise because the driven wheel 403 rotates clockwise. Under the push of the second ratchet teeth 4031 of the driven wheel 403, the second ratchet shaft 4042 rotates clockwise to output torque. In this way, when the output shaft 304 rotates clockwise, power is distributed to the first ratchet shaft 402 , and when the output shaft 304 rotates counterclockwise, power is distributed to the second ratchet shaft 404 .

[0107] In some embodiments, the second chamber 1C has two mutually isolated first flow guide channels 1014 and second flow guide channels 1015. For example, two mutually isolated first flow guide channels 1014 and second flow guide channels 1015 can be formed by injection molding in the second chamber 1C. Exemplarily, the first dispensing mechanism 5 is a pump body disposed in the first flow guide channel 1014. It is understood that the first dispensing mechanism 5 can be an independent pump body or a pump body formed in cooperation with the inner wall surface of the first flow guide channel 1014. Exemplarily, the second dispensing mechanism 6 is a pump body disposed in the second flow guide channel 1015. It is understood that the second dispensing mechanism 6 can be an independent pump body or a pump body formed in cooperation with the inner wall surface of the second flow guide channel 1015.

[0108] For example, Figure 1 As shown, the housing 1 further includes a second end cover 103, and the second end cover 103 cooperates with the housing 101 to form a second chamber 1C. The second chamber 1C has a first liquid inlet 1016, a first liquid outlet 10117, a second liquid inlet 1018, and a second liquid outlet 1019. In the case where the first guide channel 1014 and the second guide channel 1015 are formed in the second chamber 1C and are isolated from each other, as shown in FIG. Figure 7 As shown, the first guiding channel 1014 has a first liquid inlet 1016 and a first liquid outlet 1017. The second guiding channel 1015 has a second liquid inlet 1018 and a second liquid outlet 1019.

[0109] It is understandable that when the first dispensing mechanism 5 and / or the second dispensing mechanism 6 is a pump body, the input shaft of the pump body can be driven by the first ratchet shaft 402 or the second ratchet shaft 404, thereby realizing automatic dispensing of detergent. Here, the pump body can be a plunger pump, a vane pump, a diaphragm pump, a gear pump, etc., and this application does not make specific limitations on this.

[0110] In some embodiments, Figure 7 As shown, the first ratchet shaft 402 drives the first dispensing mechanism 5, and the second ratchet shaft 404 drives the second dispensing mechanism 6. The first dispensing mechanism 5 includes a first gear 501 and a second gear 502 disposed in the first guide channel 1014. The first gear 501, the second gear 502 and the inner wall of the first guide channel 1014 cooperate to form a gear pump. When the first ratchet shaft 402 drives the first gear 501 to rotate, for example, Figure 7 As shown, when the first ratchet shaft 402 rotates counterclockwise, the first gear 501 rotates counterclockwise, and the second gear 502 meshing with the first gear 501 rotates clockwise. Under the cooperation of the first gear 501 and the second gear 502, the detergent enters through the first liquid inlet 1016, fills the tooth gap, and then is squeezed out through meshing, flows out from the first liquid outlet 1017, and is distributed to the corresponding pipeline or container; the second distribution mechanism 6 includes a third gear 601 and a fourth gear 602 arranged in the second guide channel 1015. The third gear 601 and the fourth gear 602 cooperate with the inner wall of the second guide channel 1015 to form a gear pump. When the second ratchet shaft 404 drives the third gear 601 to rotate, for example, Figure 7 As shown, when the second ratchet shaft 404 rotates counterclockwise, the third gear 601 rotates counterclockwise, and the fourth gear 602 meshing with the third gear 601 rotates clockwise. With the cooperation of the third gear 601 and the fourth gear 602, the detergent enters through the second liquid inlet 1018, fills the tooth gap, and is then squeezed out through meshing, flows out from the second liquid outlet 1019, and is distributed to the corresponding pipeline or container.

[0111] In some embodiments, Figure 8 and Fig. 9 As shown, the first dispensing mechanism 5 and / or the second dispensing mechanism 6 can also be a pump body that moves back and forth under the drive of an external force.

[0112] like Fig. 9As shown, the first dispensing mechanism 5 includes: a first pump housing 503, a first one-way valve 504, a second one-way valve 505 and a first crank slider mechanism 507, wherein a first pump inner cavity 506 is formed in the first pump housing 503, the first pump inner cavity 506 is connected to the first liquid inlet 1016 via the first one-way valve 504, and the detergent can enter the first pump inner cavity 506 unidirectionally through the first liquid inlet 1016 and the first one-way valve 504; the first pump inner cavity 506 is connected to the first liquid outlet 1017 via the second one-way valve 505, and the detergent in the first pump inner cavity 506 can be discharged unidirectionally through the second one-way valve 505 and the first liquid outlet 1017. The first crank slider mechanism 507 can convert the circumferential motion into the linear reciprocating motion under the drive of the first ratchet shaft 402, so that the slider matched with the first pump inner cavity 506 moves back and forth along the inner wall surface of the first pump inner cavity 506, so as to drive the detergent to enter unidirectionally through the first liquid inlet 1016 and the first check valve 504, and to be discharged unidirectionally through the second check valve 505 and the first liquid outlet 1017. Among them, the first crank slider mechanism 507 refers to a planar connecting rod mechanism that uses a crank and a slider to realize the mutual conversion between rotation and movement, and the specific structure is not repeated here.

[0113] like Fig. 9 As shown, the second dispensing mechanism 6 includes: a second pump housing 603, a third one-way valve 604, a fourth one-way valve 605 and a second crank slider mechanism 607, wherein a second pump inner cavity 606 is formed in the second pump housing 603, the second pump inner cavity 606 is connected to the second liquid inlet 1018 via the third one-way valve 604, and the detergent can enter the second pump inner cavity 606 unidirectionally through the second liquid inlet 1018 and the third one-way valve 604; the second pump inner cavity 606 is connected to the second liquid outlet 1019 via the fourth one-way valve 605, and the detergent in the second pump inner cavity 606 can be discharged unidirectionally through the fourth one-way valve 605 and the second liquid outlet 1019. The second crank slider mechanism 607 can convert the circumferential motion into the linear reciprocating motion under the drive of the second ratchet shaft 404, so that the slider matched with the second pump inner cavity 606 moves back and forth along the inner wall surface of the second pump inner cavity 606, so as to drive the detergent to enter unidirectionally through the second liquid inlet 1018 and the third one-way valve 604, and to be discharged unidirectionally through the fourth one-way valve 605 and the second liquid outlet 1019. Among them, the second crank slider mechanism 607 refers to a planar connecting rod mechanism that uses a crank and a slider to realize the mutual conversion between rotation and movement, and the specific structure is not repeated here.

[0114] From the above description, it can be known that during the operation of the detergent dispensing device of the embodiment of the present application, when water flows into the first chamber 1A through the first water inlet 1011, the rotating mechanism 2 rotates clockwise; when water flows into the first chamber 1A through the second water inlet 1012, the rotating mechanism 2 rotates counterclockwise; when the first water inlet 1011 and the second water inlet 1012 are controlled to simultaneously inlet water at a similar flow rate, the forward and reverse power of the rotating mechanism 2 cancel each other out, and the rotating mechanism 2 remains stationary, but the water can flow out normally through the water outlet 1013. After the rotation of the rotating mechanism 2 is decelerated and torque-increased by the speed reduction mechanism 3, the increased power is transmitted to the power distribution mechanism 4; the power distribution mechanism 4 distributes the increased power, and one form of the distributed power is distributed to the first distribution mechanism 5 through the first output end, and the other form of the distributed power is distributed to the second distribution mechanism 6 through the second output end. The first dispensing mechanism 5 controls the dispensing of detergent at the first liquid inlet 1016, and the second dispensing mechanism 6 controls the dispensing of detergent at the second liquid inlet 1018, so that different types of detergents can be automatically dispensed according to classification, and a detergent dispensing device is shared, thereby further reducing the control cost.

[0115] The embodiment of the present application also provides a washing device, including the detergent dispensing device of the embodiment of the present application. Based on the aforementioned detergent dispensing device, the washing device can use the water flow of the waterway to achieve automatic dispensing of detergent. It is understandable that the washing device can achieve classified automatic dispensing of different types of detergents based on the detergent dispensing device.

[0116] In the embodiment of the present application, the washing device may be a washing machine or a dishwasher. Taking a washing machine as an example, the washing machine includes: a box, a washing tub, and a water supply pipeline. A storage cavity for storing detergents is also provided on the box. The storage cavity may include a first cavity for storing a first detergent and a second cavity for storing a second detergent. The first water inlet 1011 and the second water inlet 1012 of the detergent delivery device are connected to the water inlet pipeline via a solenoid valve. The first liquid inlet 1016 is connected to the first cavity, and the second liquid inlet 1018 is connected to the second cavity. The water outlet 1013 and the first liquid outlet 1017 and the second liquid outlet 1019 can all be connected to the washing tub. When different detergents need to be delivered, the solenoid valve can be controlled to conduct different water inlets so that different dispensing mechanisms work to extract and deliver detergents; when normal water inlet is required, the solenoid valve can be controlled to conduct the first water inlet 1011 and the second water inlet 1012 at the same time. In this way, automatic classification delivery of different types of detergents can be achieved.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
