Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of detergent dispensers, and further relate to the cleaning machine of application of this detergent dispenser. BACKGROUND

[0002] When cleaning machine such as dishwasher, washing machine is in cleaning work, it needs to distribute detergent into the washing cavity of machine body, so as to clean bowl and chopsticks, clothes. For example, in the field of dishwasher, detergent includes dishwashing powder, dishwashing liquid, rinsing agent, etc. The existing cleaning machine can be configured with a dispenser, and the detergent is placed in the detergent dispenser before cleaning. Then, during the cleaning process, the detergent in the detergent dispenser is sequentially distributed into the washing cavity of the machine body based on the cleaning steps and through a driving mechanism, thereby achieving better cleaning effect.

[0003] According to the working characteristics of different detergents, different detergents are put in at different times based on the cleaning period in the cleaning machine. For example, dishwashing powder, dishwashing liquid and rinsing agent are stored in the dishwasher at the same time. During the early low-temperature cleaning stage, dishwashing powder and dishwashing liquid with low-foaming characteristics are put in at the same time, so that the dishwasher quickly enters the working state. However, during the last cleaning process, when the water temperature reaches a high temperature, the non-foaming rinsing agent put in hot water plays a good rinsing effect. However, in order to complete the work of putting in multiple detergents, a corresponding number of driving mechanisms are usually configured to drive the corresponding detergent dispensing structures.

[0004] The Chinese invention patent application with publication number CN119073857A (application number 202411394618.0) "Distributor and dishwasher" discloses a distributor that can simultaneously realize the dispensing of three kinds of detergents. A first liquid tank, a second liquid tank and a solid tank are respectively provided for the three kinds of detergents. The distributor is provided with a sliding sealing assembly, a first dispensing assembly and a second dispensing assembly corresponding to the first liquid tank, the second liquid tank and the solid tank to realize the dispensing of the detergents therein. The distributor is also provided with a driving assembly. The output end of the driving assembly is switchingly connected to the sliding sealing assembly, the first dispensing assembly and the second dispensing assembly. When the output end of the driving assembly rotates forward, the sliding sealing assembly and the first dispensing assembly are sequentially driven to open, and the solid tank and the first liquid tank are sequentially subjected to a dispensing action. When the output end of the driving assembly rotates reversely, the second dispensing assembly opens, and the second liquid tank is subjected to a dispensing action. The driving assembly of the distributor has high integration, which reduces the occupied space. However, in this structure, the driving assembly needs to be drivingly connected to the three dispensing assemblies, so the distribution positions of the three detergent storage tanks have high requirements, and the design flexibility of the positions of the three detergent storage tanks is low. When the space cannot meet the driving connection of the driving assembly and the three dispensing assemblies, the dispensing of the three kinds of detergents at different times cannot be realized.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figs. 1 to 4 As shown, the detergent dispenser in this embodiment includes a storage module 100, a dispensing module 200, a drive assembly 7, and a transmission assembly 8.

[0035] The storage module is mainly used for storing detergents. In the embodiment, the storage module includes a first storage bin 1, a second storage bin 2 and a third storage bin 3. The specific detergents stored in the storage bins are determined according to the specific type of the cleaning machine and the differences in the types and feeding sequence of the detergents. Based on the three storage bins, up to three types of detergents can be stored. Of course, the same type of detergent can be stored in the three storage bins, or one type of detergent can be stored in two storage bins and another type of detergent can be stored in the other storage bin. In the embodiment, dishwashing liquid is stored in the first storage bin 1, rinsing agent is stored in the second storage bin 2, and dishwashing powder is stored in the third storage bin 3. Based on the cooperation of the feeding module 200, the driving assembly 7 and the transmission assembly 8, the detergents in the first storage bin 1 and the third storage bin 3 can be fed at the same time, and the detergent in the second storage bin 2 can be fed at different times.

[0036] Each storage bin in the embodiment has a storage cavity, and a filling port and a feeding port are arranged on each storage bin.

[0037] The feeding module 200 includes a first feeding mechanism 4 arranged at the feeding port of the first storage bin 1 and used for opening and closing the feeding port, a second feeding mechanism 5 arranged at the feeding port of the second storage bin 2 and used for opening and closing the feeding port, and a third feeding mechanism 6 arranged at the feeding port of the third storage bin 3 and used for opening and closing the feeding port. The first feeding mechanism 4, the second feeding mechanism 5 and the third feeding mechanism 6 are respectively used for feeding the detergents in the corresponding storage bins. The specific types of the first feeding mechanism 4, the second feeding mechanism 5 and the third feeding mechanism 6 are determined according to the characteristics of the detergents in the corresponding storage bins. In the embodiment, since the first storage bin 1 and the second storage bin 2 store liquid detergents, a piston pump is used as the feeding mechanism. Specifically, the first feeding mechanism 4 uses a first piston pump, and the second feeding mechanism 5 uses a second piston pump. Based on the working characteristics of the reciprocating piston movement of the piston pump, in order to avoid back suction of the detergent and effectively feed the detergent, the first piston pump is connected between the cavity of the first storage bin 1 and the feeding port, and a first one-way valve 42 is further arranged at the outlet of the first piston pump. The second piston pump is connected between the cavity of the second storage bin 2 and the feeding port, and a second one-way valve 52 is further arranged at the outlet of the second piston pump. The first one-way valve 42 and the second one-way valve 52 only allow the detergent to flow outward and prevent the detergent from flowing back to the storage cavity.

[0038] The third storage bin 3 is used for storing dishwashing powder. Based on the characteristics of the dishwashing powder, the third storage bin 3 is directly provided as a box body structure with an opening facing the washing cavity. The opening constitutes a dropping port of the third storage bin 3. The third dropping mechanism 6 is a cover body that slides up and down to cover the dropping port of the third storage bin 3. Based on the sliding of the cover body relative to the dropping port, the opening and closing of the dropping port of the third storage bin 3 are realized. In order to ensure the sliding reliability, a sliding rail and a roller are matched and arranged on the door body and the third storage bin 3.

[0039] The output end of the driving assembly 7 is drivingly connected with the first dispensing mechanism 4 based on a first direction rotation, and is drivingly connected with the second dispensing mechanism 5 based on a second direction rotation, the first direction and the second direction being opposite rotation directions of the output end of the driving assembly 7. With the effective time-division driving of the first dispensing mechanism 4 and the second dispensing mechanism 5, the time-division dispensing of the washing agent in the first storage bin 1 and the second storage bin 2 is realized. In the embodiment, the driving assembly 7 is connected with the first dispensing mechanism 4 through a first one-way gear 71, and is connected with the second dispensing mechanism 5 through a second one-way gear 72, the driving rotation directions of the first one-way gear 71 and the second one-way gear 72 being opposite. Specifically, the driving assembly 7 in the embodiment is the same as the commonly used driving mechanism in the prior art, and includes a motor 701 and a driving gear set 702 connected at the driving end of the motor 701. The terminal driving gear in the driving gear set 702 is drivingly connected with the first one-way gear 71 and the second one-way gear 72, and the first one-way gear 71 and the second one-way gear 72 can only rotate in opposite one-way directions. The first one-way gear 71 and the second one-way gear 72 are time-division driven based on the opposite rotation directions of the motor 701. In the embodiment, the two opposite rotation directions of the output end of the driving assembly 7, i.e., the first direction and the second direction, are realized based on the forward and reverse rotation of the motor 701, and the matching relationship between the forward and reverse rotation of the motor 701 and the first direction and the second direction is determined based on the driving connection relationship between the motor 701 and the driving gear set 702 and the driving gear set 702. For example, when the motor 701 rotates forward, the driving end of the driving gear set 702 can rotate in the first direction, and when the motor 701 rotates reversely, the driving end of the driving gear set 702 can rotate in the second direction. Alternatively, when the motor 701 rotates forward, the driving end of the driving gear set 702 can rotate in the second direction, and when the motor 701 rotates reversely, the driving end of the driving gear set 702 can rotate in the first direction. In the embodiment, one of the rotation direction correlation schemes is taken as an example for illustration, i.e., when the motor 701 rotates forward, the output end of the driving gear set 702 rotates in the first direction, and the driving gear set 702 can be engaged with the first one-way gear 71 to drive the first one-way gear 71 to rotate, while the second one-way gear 72 cannot be engaged with the driving gear set 702 to rotate, and the second one-way gear 72 remains stationary. When the motor 701 rotates reversely, the second one-way gear 72 is driven to rotate based on the same principle, while the first one-way gear 71 remains stationary.

[0040] The first piston pump is in driving connection with the first one-way gear 71 through the engagement of the first gear 711. A first linear hole 43 is formed on the piston rod of the first piston pump in a direction perpendicular to the piston movement direction of the first piston pump. A first limiting rod is eccentrically arranged on the end face of the first gear 711 and is arranged in the first linear hole 43. When the first one-way gear 71 rotates, the first gear 711 will rotate, and the first limiting rod on the first gear 711 will change the position in the up-down direction. Thus, with the relative left-right movement of the first limiting rod in the first linear hole 43, the first piston rod moves up and down, realizing the reciprocating piston action of the first piston pump and the dispensing of the detergent in the first storage bin 1.

[0041] The second piston pump is in driving connection with the second one-way gear 72 through the engagement of the second gear 721. A second linear hole 53 is formed on the piston rod of the second piston pump in a direction perpendicular to the piston movement direction of the second piston pump. A second limiting rod is eccentrically arranged on the end face of the second gear 721 and is arranged in the second linear hole 53. The second one-way gear 72 realizes the reciprocating driving action of the second piston pump when it rotates, and realizes the dispensing of the detergent in the second storage bin 2, similar to the driving relationship of the first one-way gear 71, the first gear 711 and the first piston rod.

[0042] In order to effectively count the dispensing amount of the detergent in the first storage bin 1 and the second storage bin 2, and then facilitate the reminder of adding the detergent, the dispensing module 200 further comprises a counting component for counting the dispensing times of the first dispensing mechanism 4 and the dispensing times of the second dispensing mechanism 5.

[0043] In the embodiment, the counting component specifically comprises a first micro switch 201 for counting the dispensing times of the first dispensing mechanism 4 and a second micro switch 202 for counting the dispensing times of the second dispensing mechanism 5. The first micro switch 201 is arranged close to the first dispensing mechanism 4, and the first dispensing mechanism 4 is provided with a first trigger 41 for triggering the first micro switch 201 when the first dispensing mechanism 4 performs the dispensing action. In the embodiment, the first trigger 41 is specifically arranged on the piston rod of the first piston pump. The second micro switch 202 is arranged close to the second dispensing mechanism 5, and the second dispensing mechanism 5 is provided with a second trigger 51 for triggering the second micro switch 202 when the second dispensing mechanism 5 performs the dispensing action. In the embodiment, the second trigger 51 is specifically arranged on the piston rod of the second piston pump. When the first piston rod and the second piston rod act to open the dispensing opening of the first storage bin 1 and the dispensing opening of the second storage bin 2, the first trigger 41 on the first piston rod can trigger the first micro switch 201, and the second trigger 51 on the second piston rod can trigger the second micro switch 202. Through the action times of the first micro switch 201 and the second micro switch 202, the opening times of the dispensing openings of the first storage bin 1 and the second storage bin 2 can be counted. Since the amount of the detergent dispensed each time the dispensing opening is opened is relatively stable, the dispensing amount of the detergent can be calculated based on the counting.

[0044] Of course, the counting component can also adopt other components as needed, such as a counter built into the motor 701 controller. Through the counter, the number of times of forward rotation and reverse rotation of the motor 701 can also be counted to achieve the counting of the number of dispensing times of the first dispensing mechanism 4 and the second dispensing mechanism 5. Alternatively, the counting component can adopt a multi-contact switch, and the first trigger 41 on the first dispensing mechanism 4 and the second trigger 51 on the second dispensing mechanism 5 respectively touch different contacts on the multi-contact switch, and the number of times of triggering different contacts is counted to achieve the purpose of counting the number of dispensing times of the first dispensing mechanism 4 and the second dispensing mechanism 5. In addition, the counting component can also adopt a single micro switch, and the first trigger 41 on the first dispensing mechanism 4 and the second trigger 51 on the second dispensing mechanism 5 both trigger the micro switch when the first dispensing mechanism 4 and the second dispensing mechanism 5 open their corresponding dispensing openings. The counting of the micro switch, combined with the forward and reverse rotation information of the motor 701, realizes the counting of the number of dispensing times of the first dispensing mechanism 4 and the second dispensing mechanism 5.

[0045] The transmission assembly 8 is transmissionally connected between the first dispensing mechanism 4 and the third dispensing mechanism 6. When the first dispensing mechanism 4 opens the dispensing opening of the first storage bin 1, the third dispensing mechanism 6 is driven to open the dispensing opening of the third storage bin 3. When the first dispensing mechanism 4 closes the dispensing opening of the first storage bin 1, the third dispensing mechanism 6 is driven to close the dispensing opening of the third storage bin 3. Specifically, the piston rod of the first piston pump and the cover of the third dispensing mechanism 6 are transmissionally connected through the transmission assembly 8. When the first dispensing mechanism 4 opens the dispensing opening of the first storage bin 1, based on the transmission of the transmission assembly 8, the third dispensing mechanism 6 is driven to act, and then the dispensing opening of the third storage bin 3 is opened, realizing the simultaneous dispensing of the detergents in the first storage bin 1 and the third storage bin 3. Correspondingly, when the first dispensing mechanism 4 is reset to close the dispensing opening of the first storage bin 1, based on the transmission of the transmission assembly 8, the third dispensing mechanism 6 will also perform a reset action, and then the dispensing opening of the third storage bin 3 is closed, ending the dispensing of the detergents in the first storage bin 1 and the third storage bin 3.

[0046] The transmission assembly 8 is simple in structure and includes a transmission rod 81, a transmission gear set 82, and a limiting spring 83. The transmission rod 81 is in transmission connection with the first piston rod in the first dispensing mechanism 4, that is, the transmission rod 81 can be driven to move up and down along with the up-and-down movement of the piston rod. The transmission gear set 82 is in transmission connection with the transmission rod 81 and the third dispensing mechanism 6. Specifically, the transmission rod 81 drives an input gear in the transmission gear set 82 to rotate along with the up-and-down movement of the transmission rod 81, thereby driving the cover to move up and down. The limiting spring 83 is connected with the transmission rod 81 and has an elastic tendency to press the transmission rod 81 and the first dispensing mechanism 4. In this embodiment, the limiting spring 83 has a tendency to press the transmission rod 81 upward, and the first piston rod is provided with a limiting portion that presses the transmission rod 81. Thus, the transmission rod 81 and the first piston rod are always in transmission connection based on the relative action of the limiting portion and the limiting spring 83, and the transmission rod 81 can move along with the up-and-down movement of the first piston rod. When the first piston rod moves downward to close the dispensing opening of the first storage bin 1, the transmission rod 81 moves downward along with the first piston rod, thereby resetting the transmission rod 81. After the transmission rod 81 is reset, the transmission gear set 82 is also reset correspondingly.

[0047] The third storage bin 3 is also provided with a reset spring 61 connected with the cover. The reset spring 61 has a tendency to pull the cover to close the dispensing opening. The cover is provided with an acting portion 62. An output gear of the transmission gear set 82 is connected with a driving rod 821 in contact with the acting portion 62. The driving rod 821 exerts a force on the acting portion 62 based on the rotation of the output gear to open the cover or releases the force on the acting portion 62 to close the cover.

[0048] When the first piston rod moves upward to open the dispensing opening of the first storage bin 1, the transmission rod 81 moves upward along with the first piston rod. The transmission rod 81 drives the transmission gear set 82 to rotate, thereby driving the driving rod 821 to rotate. As the end of the driving rod 821 in contact with the acting portion 62 moves upward, the acting portion 62 of the cover is pushed to move upward, thereby opening the dispensing opening of the third storage bin 3 and achieving the dispensing of the dishwashing powder. When the storage in the first storage bin 1 is completely dispensed, the first piston rod moves downward to close the dispensing opening of the first storage bin 1. The dishwashing liquid is completely dispensed. At the same time, the transmission rod 8 moves downward along with the first piston rod. Correspondingly, the transmission gear set 82 is reset to rotate, the driving rod 821 releases the force on the acting portion 62, and the cover moves downward under the action of the reset spring 61 to reset, thereby closing the dispensing opening of the third storage bin 3.

[0049] The detergent dispenser in the utility model, drive assembly 7 is also integratedly arranged to realize the opening action of the first dropping mechanism 4 and the second dropping mechanism 5 through forward and reverse rotation, and further realize the time-sharing dropping of the detergent in the first storage bin 1 and the second storage bin 2, and the simultaneous opening of the first dropping mechanism 4 and the third dropping mechanism 6 is realized through the transmission mechanism, and further realize the simultaneous dropping of the detergent in the first storage bin 1 and the third storage bin 3. Based on the arrangement of the transmission mechanism, the dropping time sequence corresponding to the cleaning effect of the detergent is met, and since the drive assembly 7 does not need to be drivingly connected with each dropping mechanism, the relative position relationship of each storage bin is reduced, the flexibility of the setting position of each storage bin is increased, and in addition, since the drive assembly 7 does not need to be drivingly connected with each dropping mechanism, the design difficulty of the specific component of the drive assembly 7 can also be reduced.

[0050] The detergent dispenser in the embodiment is suitable for the cleaning machine needing to drop multiple detergents, and is particularly suitable for the cleaning machine needing two time-sharing dropping times.

[0051] The utility model relates to a kind of cleaning machines, including the machine body with cleaning cavity, and the machine body is equipped with the detergent dispenser as described above. According to the different types of cleaning machine, the specific setting position of detergent dispenser can be selected, such as when applied in dishwasher, detergent dispenser can be set in its door body.

[0052] The cleaning machine applied with the aforementioned detergent dispenser has low space layout requirement for the setting of detergent dispenser, and improves design flexibility.

[0053] Directional terms used in the specification and claims of the utility model, such as "front", "back", "up", "down", "left", "right", "side", "top", "bottom" and the like, are used to describe various example structural parts and elements of the present application, but these terms are only used for the purpose of convenient description, and are determined based on the example orientation shown in the drawings. Since the disclosed embodiments of the present application can be arranged in different directions, these directional terms are only used for description and should not be regarded as limitation, such as "up" and "down" are not necessarily limited to the direction opposite or consistent with the direction of gravity.
