Description

DISPENSER AND WASHING APPLIANCE CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to and benefits of Chinese Patent

Applications No. 201910603596.7, 201921053613.6, 201910603908.4, 201921053592.8, and

201921053591.3, filed with China National Intellectual Property Administration on July 5,

2019, the entire disclosures of which are incorporated herein by their references.

TECHNICAL FIELD

[0002] The present disclosure relates to the field of washing technologies, and more

particularly, to a dispenser and a washing appliance.

BACKGROUND

[0003] At present, in dishwashers, dispensers are usually used to dispense washing substances, such as powders, liquids, or tablets, into the dishwashers. The powders, liquids, or

tablets dissolve to form detergents for washing dishes. However, a washing substance in a

dispenser may fail to fall into the dishwasher totally. For example, a powder washing substance

may stick to the dispenser.

SUMMARY

[0004] Implementations of the present disclosure provide a dispenser and a washing

appliance.

[0005] The dispenser according to the implementations of the present disclosure is applied

in a washing appliance. The dispenser includes: a main body having an accommodating

chamber and a water inlet channel in communication with the accommodating chamber,

wherein the accommodating chamber has an opening located at a top portion of the main body, the opening allows a detergent to be added and allows a liquid injected from the water inlet channel into the accommodating chamber to overflow to be discharged to an outside of the dispenser; and a cover body configured to selectively open or close the opening.

[0006] In the dispenser according to the implementations of the present disclosure, with the settings of the water inlet channel and the accommodating chamber of the dispenser, water is allowed to flow into the accommodating chamber through the water inlet channel, and further, since the opening is located at the top portion of the main body, it is uneasy for the water in the accommodating chamber to flow out of the dispenser, and there is enough water in the accommodating chamber to dissolve a detergent. Therefore, the detergent can be fully mixed with the water before overflowing through the opening to the outside of the dispenser. Such a structure is simple and easy to implement.

[0007] The washing appliance according to the implementations of the present disclosure includes the dispenser as described above.

[0008] In the washing appliance according to the implementations of the present disclosure, with the water inlet channel and the accommodating chamber of the dispenser, water is allowed to flow into the accommodating chamber through the water inlet channel, and further, since the opening is located at the top portion of the main body, the water in the accommodating chamber is unlikely to flow out of the dispenser, and there is enough water in the accommodating chamber to dissolve a detergent. Therefore, the detergent can be fully mixed with the water before overflowing to the outside of the dispenser through the opening. Such a structure is simple and easy to implement.

[0009] Additional aspects and advantages of the present disclosure will be given at least in part in the following description, or become apparent at least in part from the following description, or can be learned from practicing of the present disclosure.

[0027] Embodiment 1

[0028] FIG. 1 illustrates a schematic three-dimensional view of a washing appliance 1000

according to an implementation of the present disclosure. In an example illustrated in FIG. 1,

the washing appliance 1000 is a drawer-type washing appliance. It can be understood that, in

other implementations, the washing appliance 1000 may be a washing appliance with other

structures, e.g., a washing appliance having a pull-down door. Detailed description will be made

below by taking the washing appliance 1000 being the drawer-type washing appliance as an

example.

A

[0029] The washing appliance 1000 according to the implementation of the present

disclosure includes a chamber body 200 and a dispenser 100. The chamber body 200 has a

washing chamber 201 formed therein, and the dispenser 100 is mounted on an inner wall 2011

of the chamber body 200.

[0030] Specifically, in this implementation, the washing appliance 1000 may be, e.g., a dishwasher (for example, a drawer-type dishwasher) and a cleaning machine (for example, a

drawer-type cleaning machine). In addition, generally, referring to FIG. 1, the washing

appliance 1000 further includes a housing 300, and the chamber body 200 is located in the

housing 300. The housing 300 may be made of a metallic material, e.g., a lightweight aluminum

material, such that the housing 300 may have a relatively light weight. In this case, the chamber

body 200 can also be made of a metallic material or a heat-resistant plastic material, as long as

strength and heat resistance of the chamber body 200 can be guaranteed.

[0031] It should be noted that, in this implementation, the dispenser 100 is mounted on the

inner wall 2011 of the washing chamber 201. It can be understood that, in other implementations,

the dispenser 100 may be separately placed in the washing chamber 201 as a separate

component. For example, the dispenser 100 may be detachably mounted on a carrying basket

such as a dish basket of a dishwasher in a preferable manner that a cover body 20 is not hindered

by dishware from opening. In the present disclosure, description is made by taking the dispenser

100 being mounted on the inner wall 2011 of the washing chamber 201 (as illustrated in FIG.

1) as an example.

[0032] In the implementations of the present disclosure, description is made by taking the

washing appliance 1000 being the drawer-type dishwasher as an example. In the

implementation illustrated in FIG. 1, the washing appliance 1000 is the drawer-type dishwasher.

The chamber body 200 can be connected to the housing 300 through a guide rail (not illustrated

in the figure), and the chamber body 200 can slide relative to the housing 300 to slide out of or

into the housing 300 to open or close the washing chamber 201, such that the chamber body

200 can be loaded with tableware, and the drawer-type dishwasher can clean the tableware (an

arrow A in FIG. 1 indicates a sliding direction of the chamber body 200).

[0033] It can be understood that, in other implementations, the washing appliance 1000 may

alternatively be other types of dishwashers, such as a dishwasher having a pull-down door, which is not specifically limited here. It should be noted that in implementations in which the washing appliance 1000 is a dishwasher having a pull-down door, the dispenser 100 is not mounted on an inner wall of a door body but mounted on the inner wall 2011 of the washing chamber 201.

[0034] In the example of FIG. 1, the dispenser 100 is mounted on an inner wall 2011 perpendicular to the sliding direction of the chamber body 200. It can be understood that, in other implementations, the dispenser 100 may alternatively be mounted on an inner wall 2011 parallel to the sliding direction of the chamber body 200.

[0035] Referring to FIG. 2 to FIG. 6, in this implementation, the dispenser 100 includes a main body 10, the cover body 20, a bottom plate 30, and a drive assembly 40. The cover body 20 is slidably connected to the main body 10. The bottom plate 30 is movably connected to the main body 10, and the drive assembly 40 is connected to the cover body 20 and the bottom plate 30. It should be noted that the cover body 20 being movably arranged on the main body 10 may mean that the cover body 20 is slidably or rotatably arranged on the main body 10. In the present disclosure, detailed explanation is made by taking the cover body 20 being slidably arranged on the main body 10 as an example. It can be understood that, in other implementations, the cover body 20 may alternatively be rotatably arranged on the main body 10, e.g., the cover body 20 may be arranged in an upward flip cover manner.

[0036] Referring to FIG. 4, specifically, the main body 10 includes an accommodating chamber body 11, a first guiding portion 12, and a mounting plate 14, and the accommodating chamber body 11 is mounted on the mounting plate 14. The accommodating chamber body 11 is connected on the mounting plate 14.

[0037] The accommodating chamber body 11 has an accommodating chamber 111 defined therein, and the accommodating chamber 111 has an opening 110 located at a top portion of the main body 10. The first guiding portion 12 is configured to guide the cover body 20 to slide on the main body 10. The main body 10 may be made of a plastic material. In an example, the main body 10 may be made of a polypropylene (PP) material. It can be understood that the main body 10 may be an integrally formed structure or a split-body molded structure, which is not specifically limited here.

[0038] The accommodating chamber 111 can be configured to carry a detergent for cleaning tableware, and the detergent can be in a form of powder, liquid, or tablet. That is, the user can open the opening 110 of the accommodating chamber 111 by sliding the cover body 20, and then load the detergent into the accommodating chamber 111 from the opening 110.

[0039] It should be noted that, in this implementation, the opening 110 being located at the top portion of the main body 10 can be understood as the opening 110 facing upwards, or the opening 110 being defined on a side wall of the accommodating chamber body 11, where the opening 110 faces towards an outer side of the side wall, or the opening 110 is defined in a side wall of the accommodating chamber body 11 and is inclined upwards.

[0040] In the examples illustrated in FIG. 1 and FIG. 2, the opening 110 of the washing chamber 201 of the chamber body 200 and the opening 110 of the accommodating chamber 111 of the dispenser 100 have the same direction and both face upwards.

[0041] Referring to FIG. 3 and FIG. 4, in this implementation, the accommodating chamber 111 includes a first accommodating chamber 1111 and a second accommodating chamber 1112 that are arranged in parallel. Specifically, the first accommodating chamber 1111 and the second accommodating chamber 1112 are arranged along a sliding direction of the cover body 20 (an arrow B in FIG. 3 indicates the sliding direction of the cover body). The opening 110 includes a first opening 1101 and a second opening 1102, both of which are located at the top portion of the main body 10. The first accommodating chamber 1111 has the first opening 1101. The second accommodating chamber 1112 has the second opening 1102.

[0042] In the example of FIG. 3, both thefirst accommodating chamber 1111 and the second accommodating chamber 1112 are substantially in a cuboid shape. Both the first opening 1101 and the second opening 1102 are substantially in a rectangular shape. It can be understood that, in other implementations, the first accommodating chamber 1111 and the second accommodating chamber 1112 may alternatively have other regular or irregular shapes, and the first opening 1101 and the second opening 1102 may also have other regular or irregular shapes.

[0043] Specifically, a tableware washing process of the drawer-type dishwasher usually includes a prewashing stage and a main washing stage. Here, a powder detergent can be used for cleaning in the prewashing stage, and a tablet detergent can be used for cleaning in the main washing stage. In this implementation, the first accommodating chamber 1111 can be configured to carry the powder detergent used in the prewashing stage, and the second accommodating chamber 1112 can be configured to carry the tablet detergent used in the main washing stage. That is, the user can load the powder detergent into thefirst accommodating chamber 1111 via the first opening 1101, and load the tablet detergent into the second accommodating chamber 1112 via the second opening 1102.

[0044] Referring to FIG. 2 to FIG. 4, the cover body 20 is slidable on the main body 10 to

open or close the opening 110. Specifically, the cover body 20 can slide relative to the main

body 10 to open or close the first opening 1101 and the second opening 1102. In this

implementation, detailed description is made by taking the cover body 20 being able to open or

close the first opening 1101 and the second opening 1102 as an example. It should be understood

that, in other implementations, the cover body 20 may be configured to only open one of the

first opening 1101 and the second opening 1102, while the other one of the first opening 1101

and the second opening 1102 may be opened in other ways such as by providing another cover

body, which is not specifically limited here.

[0045] It should be noted that, in this implementation, the expression "the cover body 20 is

slidable on the main body 10" means that the cover body 20 can arbitrarily translate and slide

in a three-dimensional space enclosed by the main body 10, or that the cover body 20 can

arbitrarily translate and slide within a desired range larger than a space enclosed by the main

body 10 (for example, a range that extends beyond the space enclosed by the main body 10 but

does not abut against tableware placed in the washing chamber 201). It should be noted that the

three-dimensional space enclosed by the main body 10 is a smallest space formed by a regular

three-dimensional pattern that can completely accommodate the entire body 10, such as a

cuboid, or a cube, or other regular patterns.

[0046] In addition, in the implementation illustrated in FIG. 1, the dispenser 100 is mounted

on the inner wall 2011 perpendicular to the sliding direction of the chamber body 200. The

sliding direction of the cover body 20 is perpendicular to the sliding direction of the chamber

body 200. It can be understood that, in other implementations, the dispenser 100 may

alternatively be mounted on the inner wall 2011 parallel to the sliding direction of the chamber

body 200, and in these implementations, the sliding direction of the cover body 20 is parallel

to the sliding direction of the chamber body 200.

[0047] Specifically, the cover body 20 has a second guiding portion 21 and a protruding

Q portion 24. The second guiding portion 21 is configured to cooperate with and be connected to the first guiding portion 12 to guide sliding of the cover body 20 relative to the main body 10.

The protruding portion 24 is configured to be operated to drive the cover body 20 to slide

relative to the main body 10. In this manner, when the user needs to slide the cover body 20,

the user can push the protruding portion 24 to drive the cover body 20 to slide on the main body

10, thereby opening or closing the first opening 1101 and the second opening 1102.

[0048] Specifically, referring to FIG. 4, the first guiding portion 12 includes a first sliding groove 121 defined in the mounting plate 14 and a second sliding groove 122 defined in the

accommodating chamber body 11, and both the first sliding groove 121 and the second sliding

groove 122 are defined along the sliding direction of the cover body 20. A vertical plane where

an extension direction of the second sliding groove 121 is located is different from a vertical

plane where an extension direction of the second sliding groove 122 is located, and in this way,

a plurality of degrees of freedom can be defined for the cover body 20 and thus the cover body

20 can slide more smoothly and stably.

[0049] In this implementation, the cover body 20 is L-shaped, and includes a horizontal

folding portion 22 and a vertical folding portion 23. The horizontal folding portion 22 is located

at the top portion of the main body 10, and is configured to open or close thefirst opening 1101

and the second opening 1102. The protruding portion 24 is arranged on the horizontal folding

portion 22. The vertical folding portion 23 is bent relative to the horizontal folding portion 22

and is located on a side of the horizontal folding portion 22. The second guiding portion 21

includes a first convex portion 211 formed on the horizontal folding portion 22 and a first

convex portion 212 formed on the vertical folding portion 23. The first convex portion 211 is

slip fit with the first sliding groove 121, and the first convex portion 212 is slip fit with the

second sliding groove 122, thereby guiding the cover body 20 to slide on the main body 10.

[0050] It can be understood that, in other implementations, the first guiding portion 12 may

be a convex portion and the second guiding portion 21 may be a sliding groove, or the first

guiding portion 12 and the second guiding portion 21 each may include a convex portion and a

sliding groove, specific arrangements of which are not limited here, as long as relative sliding

between the cover body 20 and the main body 10 is attainable. In this implementation, the cover

body 20 can be made of a heat-resistant plastic material, such that the plastic is easy to be molded and has low cost, and further, the cover body 20 has good heat resistance. In one example, the main body 10 can be made of the PP material.

[0051] In addition, in other implementations, the vertical folding portion 23 may be omitted to make the structure of the cover body 20 simpler.

[0052] In addition, in this implementation, the cover body 20 is directly arranged at the top portion of the main body 10, and is usually a rigid member that is neither compressible nor bendable. It can be understood that, in some implementations, the cover body 20 may be a flexible member that is compressible and bendable. In such an implementation, a winding mechanism may be arranged on a side of the accommodating chamber body 11, and the cover body 20 is at least partially wound in the winding mechanism. When there is a need to close the first opening 1101 and the second opening 1102, the cover body 20 may be pulled out of the winding mechanism and then pulled to slide on the main body 10 to close the first opening 1101 and the second opening 1102. After the first opening 1101 and the second opening 1102 are closed, one end of the cover body 20 can be fixed on the main body 10 to prevent the cover body 20 from being erroneously wound in the winding mechanism. When there is a need to open the first opening 1101 and the second opening 1102, once upon loosening the one end of the cover body 20, the winding mechanism may automatically wind the cover body 20 back to open the first opening 1101 and the second opening 1102. Of course, the cover body 20 can alternatively be bent instead of being wounded.

[0053] Further, referring to FIG. 3 to FIG. 5, the main body 10 has a water inlet channel 60 and a water outlet channel 61 formed therein, the water inlet channel 60 is in communication with the second accommodating chamber 1112, the water outlet channel 61 is located at the top portion of the main body 10 and is in communication with the opening 110, and the water outlet channel 61 is configured to discharge a liquid, which is injected from the water inlet channel 60 into the accommodating chamber 111 and overflows from the opening 110, to an outside of the dispenser 100.

[0054] Here, the water inlet channel 60 is defined in the mounting plate 14. That is, the water inlet channel 60 is formed on the mounting plate 14.

[0055] Specifically, the accommodating chamber body 11 includes first plates 112 connected to the mounting plate 14, and a second plate 113 connected to the first plates 112 and

11) the second plate 13 faces towards the mounting plate 14. Here, the opening 110 is defined by the second plate 113, the first plates 112, and the mounting plate 14 together, and a top of the first plate 112 is higher than a top of the second plate 113 to define the water outlet channel 61.

[0056] Since the top of the first plate 112 is higher than the top of the second plate 113, water in the first accommodating chamber 1111 and water in the second accommodating

chamber 1112 can be prevented from being exchanged with each other. That is, if a height of

the top of the first plate 112 is smaller than a height of the top of the second plate 113, when

water is fed into thefirst accommodating chamber 1111 from the water inlet channel 60, the

water in the first accommodating chamber 1111 may flow from the first plate 112 into the

second accommodating chamber 1112, rather than flowing from the second plate 113 into the

washing chamber 201 of the washing appliance 1000. Therefore, the top of the first plate 112

being higher than the top of the second plate 113 can prevent the water in the first

accommodating chamber 1111 from flowing into the second accommodating chamber 1112.

[0057] Here, in this implementation, the first plates 112 are perpendicular to the mounting plate 14. It can be understood that, in other implementations, the first plate 112 and the

mounting plate 14 is not limited to being perpendicular to each other. A specific positional

relationship between the first plates 112 and the mounting plate 14 can be set based on different

situations, which is not limited here.

[0058] Further, an end of the first plate 112 facing away from the mounting plate 14 extends

beyond the second plate 113, so as to guide the water to a desired position. That is, water flowing

out from the second plate 113 does not flow to two sides of the second plate 113.

[0059] Here, the water inlet channel 60 and the water outlet channel 61 match each other in

quantity. That is, one water inlet channel 60 corresponds to one water outlet channel 61. Specific

numbers of water inlet channels 60 and water outlet channels 61 are illustrated below with

examples.

[0060] In an example, referring to FIG. 4, FIG. 6, and FIG. 7, the dispenser 100 includes

the bottom plate 30 movably arranged on the main body 10. When the cover body 20 opens the

opening 110 completely, a bottom of the first accommodating chamber 1111 is closed by the

bottom plate 30, and when the cover body 20 closes the opening 110 completely, the bottom of

the first accommodating chamber 1111is opened by the bottom plate 30. That is, the bottom plate 30 is movably arranged at the bottom of the first accommodating chamber 1111 and configured to open or close the bottom of thefirst accommodating chamber 1111. In this case, a bottom of the second accommodating chamber 1112 is in a closed state. That is, the bottom of the second accommodating chamber 1112 is not provided with the bottom plate 30.

[0061] In such an example, one water inlet channel 60 and one water outlet channel 61 are

provided, the water inlet channel 60 is located in the second accommodating chamber 1112,

and the water outlet channel 61 is in communication with the second opening 1102. Therefore,

a detergent in the first accommodating chamber 1111 can be discharged to the outside of the

dispenser 100 through the bottom plate 30, and for a detergent in the second accommodating

chamber 1112, as water is fed into the second accommodating chamber 1112 through the water

inlet channel 60, the water in the second accommodating chamber 1112 dissolves the detergent

in the second accommodating chamber 1112, and when a height of water in the second

accommodating chamber 112 is higher than a height of the second opening 1102, the water

mixed with the detergent in the second accommodating chamber 1112 can be discharged to the

outside of the dispenser 100 from the second opening 1102.

[0062] Referring to FIG. 7, in this implementation, a dispensing opening 1113 is defined at

the bottom of the first accommodating chamber 1111. The bottom plate 30 is configured to open

or close the dispensing opening 1113.

[0063] Referring to FIG. 7 to FIG. 9, in this implementation, the drive assembly 40 is

connected to the bottom plate 30 and the cover body 20, and the drive assembly 40 is configured

to, in a process of the cover body 20 closing the opening 110, drive the bottom plate 30 to move

to open the bottom of thefirst accommodating chamber 1111.

[0064] The drive assembly 40 includes a first propelling member 41, a second propelling

member 42, and a first elastic member 43.

[0065] The first propelling member 41 is connected to the cover body 20, the second

propelling member 42 is connected to the bottom plate 30, and the first propelling member 41

is configured to, in a process of the cover body 20 closing the opening 110, abut against the

second propelling member 42 to enable the bottom plate 30 to gradually open the bottom of the

first accommodating chamber 1111.

[0066] Specifically, the first propelling member 41 is configured to, in a process of the

11) cover body closing the first opening 1101 and the second opening 1102, drive the bottom plate

30 to move relative to the main body 10 to gradually open the dispensing opening 1113 at the

bottom of the first accommodating chamber 1111.

[0067] The first elastic member 43 is connected to the bottom plate 30, and configured to apply an elastic force to the bottom plate 30 to maintain a tendency of the bottom plate 30

closing a bottom of the accommodating chamber 111. The first elastic member 43 may be an

elastic element such as a spring.

[0068] Specifically, in this implementation, the first elastic member 43 is connected to the bottom plate 30, and the first elastic member 43 is configured to apply an elastic force to the

bottom plate 30 to maintain a tendency of the bottom plate 30 closing the dispensing opening

1113 at the bottom of the first accommodating chamber 1111.

[0069] That is, the first elastic member 43 can be configured to, when the cover body 20 opens the first opening 1101 and the second opening 1102, apply an elastic force to the bottom

plate 30 to enable the bottom plate 30 to maintain a state of closing thefirst accommodating

chamber 1111, and the first propelling member 41 can be configured to, in a process of the

cover body 20 closing the first opening 1101 and the second opening 1102, abut against the

second propelling member 42 to enable the bottom plate 30 to overcome the elastic force of the

first elastic member 43 and gradually open the dispensing opening 1113 at the bottom of the

first accommodating chamber 1111.

[0070] It should be noted that, in this implementation, the bottom plate 30 being movable

relative to the main body 10 to open the dispensing opening 1113 at the bottom of the first

accommodating chamber 1111may mean that the bottom plate 30 is rotatable relative to the

main body 10 to open the dispensing opening 1113 or the bottom plate 30 is slidable relative to

the main body 10 to open the dispensing opening 1113.

[0071] Specifically, referring to FIG. 7, in an example, the bottom plate 30 is rotatably

arranged at the bottom of the first accommodating chamber 1111. That is, the bottom plate 30

is rotatable relative to the main body 10 to open or close the dispensing opening 1113.

[0072] Referring to FIG. 7 to FIG. 9, the bottom plate 30 includes a first rotating shaft

portion 311 rotatably connected to the main body 10, the bottom plate 30 is rotatable about the

first rotating shaft portion 311 relative to the main body 10, and the first elastic member 43 is

1'l sleeved on the first rotating shaft portion 311 and abuts against the main body 10. The first propelling member 41 is a first resisting portion 411 arranged on the cover body 20, and the second propelling member 42 is a second resisting portion 421 arranged on the bottom plate 30.

[0073] Referring to FIG. 7 to FIG. 9, in such an example, when the cover body 20 opens the entire first opening 1101, the first resisting portion 411 is separated from the second resisting

portion 421, and the bottom plate 30 closes the dispensing opening 1113 at the bottom of the

first accommodating chamber 1111 under an action of the elastic force of the first elastic

member 43.

[0074] Referring to FIG. 8 and FIG. 9, in the process of the cover body 20 closing the first

opening 1101 and the second opening 1102 (an arrow C in FIG. 7 indicates the sliding direction

along which the cover body 20 opens the first opening 1101), first the first resisting portion 411

gradually approaches the second resisting portion 421, and then the first resisting portion and

the second resisting portion 421 abut against each other, at this moment, the cover body 20

slides further under an action of an external force, the first resisting portion 411 applies a force

to the second resisting portion 421, and the second resisting portion 421 is rotated under driving

of the first resisting portion 411, such that the bottom plate 30, after overcoming the elastic

force of the first elastic member 43, is rotated relative to the main body 10 to open the

dispensing opening 1113 at the bottom of the first accommodating chamber 1111 (an arrow D

in FIG. 7 indicates a rotation direction of the bottom plate 30). Then, the powder detergent in

the first accommodating chamber 1111 is dispensed down into the washing chamber 201 of the

chamber body 200 to meet a washing requirement in the prewashing stage of the drawer-type

dishwasher.

[0075] In addition, referring to FIG. 9, when the bottom plate 30 opens the first

accommodating chamber 1111, the first resisting portion 411 and the second resisting portion

421 still abut against each other and are in surface contact with each other. In this way, thefirst

resisting portion 411 can stably abut against the second resisting portion 421, thereby

preventing erroneous rotation of the bottom plate 30 due to an action of the first elastic member

43 from closing the bottom of thefirst accommodating chamber1111.

[0076] It should be noted that since the prewashing stage is a first started washing stage of

the dishwasher, the user can close the first opening 1101 and the second opening 1102 through

1 / the cover body 20 after the detergents are loaded in the first accommodating chamber 1111 and the second accommodating chamber 1112. During a process of closing the first opening 1101 and the second opening 1102, due to the presence of the drive assembly 40, the cover body 20 may drive the bottom plate 30 to open the bottom of the first accommodating chamber 1111 to directly dispense the detergent required in the prewashing stage in a quantitative manner.

[0077] It can be understood that, in other examples, the first elastic member 43 can also be configured to, in a process of the cover body 20 closing thefirst opening 1101 and the second opening 1102, maintain a tendency of the bottom plate 30 opening thefirst accommodating chamber 1111. That is, in such examples, in a process of the cover body 20 opening the first opening 1101 andthe secondopening 1102, the elastic force of the firstelastic member43 needs to be overcome to enable the bottom plate 30 to close the first accommodating chamber 1111.

[0078] In addition, in an implementation illustrated in FIG. 7, thefirst rotating shaft portion 311 is rotatably connected to a side of the first accommodating chamber 1111, and the bottom plate 30 is configured to rotate about the side of thefirst accommodating chamber 1111 to open the dispensing opening 1113. It can be understood that, in other implementations, the first rotating shaft portion 311 may be rotatably connected to a middle position of the bottom of the first accommodating chamber 1111, such that when the bottom plate 30 is rotated, one portion of the bottom plate 30 is rotated towards an interior of thefirst accommodating chamber1111, and the other portion of the bottom plate 30 is rotated towards an exterior of the first accommodating chamber 1111, a specific arrangement manner of which is not limited here.

[0079] In addition, referring to FIG. 10 and FIG. 11, as described above, in some implementations, instead of being rotatably connected to the main body 10, the bottom plate 30 may be slidably arranged at the bottom of the first accommodating chamber 1111. That is, the bottom plate 30 can slide relative to the main body 10 to open or close the dispensing opening 1113.

[0080] In such an example, the first propelling member 41 may be a third resisting portion 412 and a fourth resisting portion 413 that are arranged on two sides of the cover body 20, and the second propelling member 42 may be a fifth resisting portion 422 arranged on the bottom plate 30 and located between the third resisting portion 412 and the fourth resisting portion 413.

[0081] Specifically, with continued reference to FIG. 10 and FIG. 11, when the cover body

I1zC

20 opens the first opening 1101 and the second opening 1102 completely, the bottom plate 30

closes the dispensing opening 1113 at the bottom of the first accommodating chamber 1111 (see

FIG. 10), and the third resisting portion 412 abuts against the fifth resisting portion 422.

[0082] Referring to FIG. 11, when there is a need to close the first opening 1101 and the second opening 1102, the cover body 20 can be slid to close the first opening 1101 and the

second opening 1102. In this process, the fourth resisting portion 413 gradually approaches the

fifth resisting portion 422, and when the fourth resisting portion 413 abuts against the fifth

resisting portion 422, the fourth resisting portion 413 continues to drive the fifth resisting

portion 422 to drive the bottom plate 30 to slide relative to the main body 10 (the sliding

direction of the bottom plate 30 is the same as the sliding direction of the cover body 20), such

that the bottom plate 30 opens the dispensing opening 1113 (see FIG. 11) at the bottom of the

first accommodating chamber 1111 to dispense the powder detergent in the first accommodating

chamber 1111 into the washing chamber 201 of the chamber body 200.

[0083] When dispensing of the detergent is completed and a next time of loading is required, the cover body 20 can be slid to open the first opening 1101 and the second opening 1102.

During a sliding process of the cover body 20, the third resisting portion 412 gradually

approaches the fifth resisting portion 422, and when the third resisting portion 412 abuts against

the fifth resisting portion 422, the third resisting portion 412 continues to drive the fifth resisting

portion 422 to move to drive the bottom plate 30 to slide relative to the main body 10 (the

sliding direction of the bottom plate 30 is the same as the sliding direction of the cover body

20), such that the bottom plate 30 gradually closes the dispensing opening 1113 at the bottom

of the first accommodating chamber 1111 (see FIG. 11). When the cover body 20 opens the

entire first opening 1101, the bottomplate 30 closes the entire dispensing opening 1113, and at

this time, the user can load the detergent into the first accommodating chamber 1111 through

the first opening 1101.

[0084] It can be understood that, in such an example, a linkage mechanism 40 may not include the first elastic member 43 as described above.

[0085] For example, in an example, the drive assembly 40 can be configured in such a

manner that when the coverbody20 closes thefirst opening 1101 andthe second opening 1102,

the bottom plate 30 moves in a direction opposite to a direction indicated by the bottom plate

1K

30 to open the bottom of the first accommodating chamber 1111, a specific arrangement manner

of which can be set based on actual situations.

[0086] Referring to FIG. 6 and FIG. 7, a working principle of the dispenser 100 of the present disclosure will be introduced below by taking the bottom of the first accommodating

chamber 1111 being provided with the bottom plate 30 and the bottom of the second

accommodating chamber 1112 being closed as an example.

[0087] First, when there is a need to load the detergent, the cover body 20 is slid to open the first opening 1101 and the second opening 1102, and at this time, the bottom plate 30 closes

the bottom of the first accommodating chamber 1111 under the action of the first elastic member

43. In this manner, the powder detergent used in the prewashing stage can be loaded in the first

accommodating chamber 1111, and the tablet detergent used in the main washing stage can be

loaded in the second accommodating chamber 1112.

[0088] Subsequently, the cover body 20 can be slid to close the first opening 1101 and the

second opening 1102. During the sliding process, the cover body 20 drives, via the drive

assembly 40, the bottom plate 30 to rotate to open the dispensing opening 1113 at the bottom

of the first accommodating chamber 1111, thereby implementing dispensing of the powder

detergent. At this time, the chamber body 200 of the drawer-type dishwasher can be pushed into

the housing 300 and the prewashing stage is entered.

[0089] After the prewashing stage is over, the main washing stag is entered. In the main

washing stage, external water is delivered into the second accommodating chamber 1112

through the water inlet channel 60. After entering the second accommodating chamber 1112,

the water can dissolve the detergent in the second accommodating chamber 1112, such that the

water and the detergent in the second accommodating chamber 1112 are fully mixed with each

other. When the water in the second accommodating chamber 1112 is higher than the second

opening 1102, since the water outlet channel 60 is in communication with the second opening

1102, the water in the second accommodating chamber 1112 will overflow from the second

opening 1102, and then flows along the water outlet channel 61 to the washing chamber 201 of

the washing appliance 1000 for use in the main washing stage.

[0090] In another example, the bottom plate 30 and the dispensing opening 1113 in the first

accommodating chamber 1111 can be omitted. That is, bottoms of both the first accommodating

1-7 chamber 1111 and the second accommodating chamber 1112 are in the closed state.

[0091] In such an example, two water inlet channels 60 and two water outlet channels 61 are provided, and arranged in one-to-one correspondence in the first accommodating chamber 1111 and the second accommodating chamber 1112. That is, one water inlet channel 60 and one water outlet channel 61 are arranged in the first accommodating chamber 1111, and one water inlet channel 60 and one water outlet channel 61 are arranged in the second accommodating chamber 1112.

[0092] In this case, the bottoms of both the first accommodating chamber 1111 and the second accommodating chamber 1112 are in the closed state. That is, neither of the bottoms of the first accommodating chamber 1111 and the second accommodating chamber 1112 is provided with the bottom plate 30 and the dispensing opening 1113.

[0093] Referring to FIG. 5 (in which dashed arrows indicate a water flow direction in the second accommodating chamber 1112, and a water flow direction in thefirst accommodating chamber 1111 is the same as the water flow direction in the second accommodating chamber 1112), in such an example, water enters the first accommodating chamber 1111 from the water inlet channel 60 in the first accommodating chamber 1111 and enters the second accommodating chamber 1112 from the water inlet channel 60 in the second accommodating chamber 1112. In this case, both the first accommodating chamber 1111 and the second accommodating chamber 1112 are fully filled with water. The water in thefirst accommodating chamber 1111 and the water in the second accommodating chamber 1112 dissolve the detergent in the first accommodating chamber 1111 and the detergent in the second accommodating chamber 1112. When the water in the first accommodating chamber 1111 is higher than the first opening 1101 and the water in the second accommodating chamber 1112 is higher than the second opening 1102, the water in the first accommodating chamber 1111 and the water in the second accommodating chamber 1112 overflow the first opening 1101 andthe second opening 1102, respectively, and then flow into the washing chamber 201 of the washing appliance 1000.

[0094] Referring to FIG. 3 and FIG. 12, a working principle of the dispenser of the present disclosure will be introduced below by taking the bottoms of both thefirst accommodating chamber 1111 and the second accommodating chamber 1112 being closed as an example.

[0095] First, when there is a need to load the detergent, the cover body 20 is slid to open

1Q the first opening 1101 and the second opening 1102, such that the tablet or powder detergent used in the prewashing stage can be loaded in the first accommodating chamber 1111, and the tablet or powder detergent used in the main washing stage can be loaded in the second accommodating chamber 1112.

[0096] Subsequently, the cover body 20 can be slid to close the first opening 1101 and the

second opening 1102. After the cover body 20 closes the first opening 1101 and the second

opening 1102, external water is delivered into thefirst accommodating chamber 1111 through

the water inlet channel 60. After entering thefirst accommodating chamber 1111, the water can

dissolve the detergent in the first accommodating chamber 1111, such that the water and the

detergent in the first accommodating chamber 1111 are fully mixed with each other. When the

water in the first accommodating chamber 1111 is higher than the first opening 1101, since the

water outlet channel 60 is in communication with the first opening 1101, the water in the first

accommodating chamber 1111 overflows from the first opening 1101, and then flows along the

water outlet channel 61 to the washing chamber 201 of the washing appliance 1000 for use in

the prewashing stage.

[0097] After the prewashing stage is over, the main washing stage is entered. In the main

the water dissolves the detergent in the second accommodating chamber 1112, such that the

1102, the water in the second accommodating chamber 1112 overflows from the second opening

1102, and then flows along the water outlet channel 60 to the washing chamber 201 of the

washing appliance 1000 for use in the main washing stage.

[0098] In addition, it should be noted that in the above different examples, volumes of the

first accommodating chamber 1111 and the second accommodating chamber 1112 are set in

advance, such that when the user loads the detergents, the first accommodating chamber 1111

and the second accommodating chamber 1112 can meter the detergents. It is appropriate to set

the volume of the first accommodating chamber 1111 to be equal to a volume of the detergent to be dispensed in each prewashing stage, and the volume of the second accommodating chamber 1112 to be greater than a volume of the tablet detergent used in each main washing stage.

[0099] Further, when the bottom of the accommodating chamber 111 is in the closed state, the accommodating chamber body 11 has a drain hole 1114 defined at the bottom of the accommodating chamber 111. That is, when the bottom of thefirst accommodating chamber 1111 is in the closed state, the drain hole 1114 is defined in the bottom of the first accommodating chamber 1111, and when the bottom of the second accommodating chamber 1112 is in the closed state, the drain hole 1114 is defined in the bottom of the second accommodating chamber 1112.

[0100] Since the water in the accommodating chamber 111 overflows from the opening 110 to the washing chamber 201 of the washing appliance 1000 when a height of the water in the accommodating chamber 111is higher than a height of the opening 110, i.e., the water in the accommodating chamber 111 does not overflow from the opening 110 when the height of the water in the accommodating chamber 111 is lower than the height of the opening 110, a large amount of water may remain in the accommodating chamber 111. With the drain hole 1114, the water lower than the opening 110 in the accommodating chamber 111 can flow out of the accommodating chamber 111 from the drain hole 1114, thereby avoiding a residual of the water mixed with the detergent in the accommodating chamber 111. In this manner, the water mixed with the detergent in the accommodating chamber 111 can fully flow into the washing chamber 201, further, washing efficiency of the washing appliance 1000 is improved, and the residual of the water mixed with the detergent in the accommodating chamber 111 is avoided.

[0101] Here, the drain hole 1114 may be circular. Of course, in other implementations, the drain hole 1114 may not limited to being circular. A specific shape of the drain hole 1114 can be set based on different situations. For example, the drain hole 1114 may be triangular, rectangular, or the like, and the specific shape of the drain hole 1114 is not limited here.

[0102] Specifically, a bottom surface of the accommodating chamber 111 is inclined downwardly towards the drain hole 1114.

[01031 When the bottom surface of the accommodating chamber 111 is horizontally flat, the water in the accommodating chamber 111 may not fully enter the drain hole 1114, thereby leading to a residual of water in the accommodating chamber 111. When the bottom surface of the accommodating chamber 111 is inclined downwardly towards the drain hole 1114, i.e., the bottom surface of the accommodating chamber 111 has an inclined surface, the inclined surface is inclined along the drain hole 1114, and the water in the accommodating chamber 111 can enter the drain hole 1114 along the inclined surface, such that the water in the accommodating chamber 111 can fully enter the drain hole 1114 before entering the washing chamber 201 of the washing appliance 1000, and it is possible to prevent the residual of water in the washing chamber 201.

[0104] In summary, the dispenser 100 according to the implementations of the present disclosure includes the main body 10 and the cover body 20. The main body 10 is formed with the accommodating chamber 111 and the water inlet channel 60 in communication with the accommodating chamber 111. The accommodating chamber 111 has the opening located at the top portion of the main body 10. The opening 110 is used for addition of the detergent, and allows the liquid injected from the water inlet channel 60 into the accommodating chamber 111 to overflow to be discharged to the outside of the dispenser 100. The cover body 20 is configured to selectively open or close the opening 110.

[0105] In the dispenser 100 according to the implementations of the present disclosure, the water inlet channel 60 and the accommodating chamber 111 of the dispenser 100 are arranged in such a manner that water can flow into the accommodating chamber 111 from the water inlet channel 60, and further, the opening 110 is located at the top portion of the main body 10, such that it is uneasy for the water in the accommodating chamber 111 to flow out of the dispenser 100, hence there is enough water in the accommodating chamber 111 to dissolve the detergent. Therefore, the detergent and the water can be fully mixed with each other before overflowing from the opening 100 to the outside of the dispenser 100. Such a structure is simple and easy to implement.

[01061 Embodiment 2

[01071 Features of the washing appliance 1000 in Embodiment 2 are substantially the same as those of the washing appliance in Embodiment 1. Explanation of the washing appliance in Embodiment 1 is applicable to the washing appliance in Embodiment 2. For simplicity, only differences between the washing appliance in Embodiment 1 and the washing appliance in

I1

Embodiment 2 will be described in detail below, and for contents other than the differences,

reference may be made to the same or similar contents of the washing appliance in Embodiment

1. The features of the washing appliance in Embodiment 1 and the features of the washing

appliance in Embodiment 2 can be combined with each other without contradiction.

[01081 Referring to FIG. 2 to FIG. 4, the cover body 20 is slidable on the main body 10 to

open or close the opening 110. Specifically, the cover body 20 is slidable on the main body 10

to open or close at least one of the first opening 1101 and the second opening 1102. That is, the

cover body 20 is configured to selectively open or close at least one of the first opening 1101

and the second opening 1102.

[0109] In this implementation, detailed description is made by taking the cover body 20

being able to open or close the first opening 1101 and the second opening 1102 as an example.

It should be understood that, in other implementations, the cover body 20 may open only one

of the first opening 1101 and the second opening 1102, while the other one of thefirst opening

1101 and the second opening 1102 may be opened in other ways such as by providing another

cover body, which not specifically limited here. In this implementation, the cover body 20 is

arranged in the accommodating chamber body 11.

[0110] Referring to FIG. 7, FIG. 13, and FIG. 14, the drive assembly 40 is arranged on the

main body 10, and configured to drive the bottom plate 30 to move, enabling the bottom plate

30 to close and open the dispensing opening.

[0111] Specifically, the drive assembly 40 includes a drive member 41 and a transmission

member 42, the transmission member 42 is connected to the bottom plate 30, and the drive

member 41 is configured to drive, via the transmission member 42, the bottom plate 30 to move

to enable the bottom plate 30 to close and open the dispensing opening 1113.

[0112] The drive assembly 40 is configured to drive the bottom plate 30 to move to open

the dispensing opening 1113.

[0113] It should be noted that, in this implementation, the bottom plate 30 being configured

to move in the three-dimensional space enclosed by the main body 10 to close or open the

dispensing opening 1113 means that the bottom plate 30 is rotatable relative to the main body

10 under the drive of the drive assembly 40 to open the dispensing opening 1113, or the bottom

plate 30 is slidable relative to the main body 10 to open the dispensing opening 1113. That is, the bottom plate 30 is rotatably or slidably connected to the main body 10. In this implementation, description is mainly given by taking the bottom plate 30 being rotatably connected to the main body 10 as an example.

[0114] Specifically, referring to FIG. 6 and FIG. 7, in an example, the bottom plate 30 is rotatably arranged at the bottom of the first accommodating chamber 1111. That is, the bottom plate 30 is rotatable relative to the main body 10 to open or close the dispensing opening 1113.

[0115] Referring to FIG. 6, FIG. 7, FIG. 13, and FIG. 14, the drive assembly 40 may be a driving device such as a solenoid valve or a motor. The bottom plate 30 includes a rotating shaft 311, and is rotatably connected to the main body 10 through the rotating shaft 311, and the rotating shaft 311 is located on a side of the bottom plate 30. The transmission member 42 is connected to the rotating shaft 311. The drive member 41 is configured to drive, via the transmission member 42, the rotating shaft 311 to rotate to enable the bottom plate 30 to rotate.

[01161 That is, the drive member 41 can drive, via the transmission member 42, the bottom plate 30 to rotate relative to the main body 10 to open the dispensing opening 1113 at the bottom of the first accommodating chamber 1111 (FIG. 7 is a schematic diagram showing a state in which the bottom plate 30 opens the dispensing opening 1113).

[01171 Specifically, referring to FIG. 13 and FIG. 14, in an example, the drive member 41 is a solenoid valve. Specifically, the solenoid valve may include a retractable ejector pin. When the solenoid valve is energized, the ejector pin is ejected, and when the solenoid valve is de energized, the ejector pin is retracted. The transmission member 42 includes a transmission rod, and the ejector pin abuts against the transmission rod. One end of the transmission rod abuts against the ejector pin of the solenoid valve, and the other end of the transmission rod isfixedly connected to the rotating shaft 311 of the bottom plate 30.

[01181 When there is a need to open the dispensing opening 1113 at the bottom of the first accommodating chamber 1111, simply by energizing the solenoid valve, the ejector pin of the solenoid valve is ejected to make the transmission rod rotate, such that the rotating shaft 311 drives the bottom plate 30 to rotate to open the bottom of the first accommodating chamber 1111, thereby realizing the dispensing of the powder detergent in the prewashing stage of the drawer-type dishwasher.

[01191 In such an example, the prewashing stage may require no manual dispensing, and the detergent can be dispensed automatically when washing is started. Such a dispensing operation is simple and reliable, and improves user experience.

[0120] In addition, it can be understood that, in such an implementation, the drive assembly 40 may further include an elastic member 43 connected to the bottom plate 30. The elastic

member 43 is configured to apply an elastic force to the bottom plate 30 to maintain a tendency

of the bottom plate 30 closing the dispensing opening 1113 at the bottom of the first

accommodating chamber 1111. Specifically, the elastic member 43 can be sleeved on the

rotating shaft 311 and abut against the main body 10. The elastic member 43 may be an elastic

element such as a spring.

[0121] That is, the elastic member 43 can be configured to: when the solenoid valve is not

in operation, apply an elastic force to the bottom plate 30 to enable a state of the bottom plate

30 closing the first accommodating chamber 1111. When the solenoid valve is energized and

operates, the ejector pin drives the transmission member 42 to drive the bottom plate 30 to

rotate, such that the bottom plate 30 can overcome the elastic force of the elastic member 43 to

gradually open the dispensing opening 1113 at the bottom of the first accommodating chamber

1111.

[0122] It should be noted that, in such an example, due to the presence of the elastic

member 43, the elastic member 43 may apply the elastic force to the bottom plate 30 constantly.

Therefore, when the bottom plate 30 opens the bottom of the first accommodating chamber

1111, the solenoid valve needs to be kept in an energized state to enable the bottom plate 30 to

be kept in a state of opening the bottom of the first accommodating chamber1111.

[01231 It can be understood that, in such an example, the elastic member 43 may also be

configured to apply an elastic force to the bottom plate 30 to maintain a tendency of the bottom

plate 30 opening the dispensing opening 1113 at the bottom of the first accommodating chamber

1111. In this manner, when the solenoid valve is de-energized, the elastic member 43 enables

the bottom plate 30 to be kept in a state of opening the dispensing opening 1113 at the bottom

of the first accommodating chamber 1111. When there is a need to load the detergent, the

solenoid valve needs to be energized to enable the bottom plate 30 to close the dispensing

opening 1113. When the detergent needs to be dispensed, simply by powering off the solenoid

valve, the bottom plate 30 can open the dispensing opening 1113 under the action of the elastic member 43, a specific arrangement manner of which can be set based on actual situations.

[0124] In addition, it can be understood that, in some implementations, the drive member 41 may be a motor, a motor shaft of the motor may be connected to the rotating shaft 311 of the bottom plate 30 through the transmission member 42, and the motor, when rotated, can drive a rotation of the bottom plate 30 via the transmission member. In such implementations, the transmission member 42 may be a transmission structure in other forms, such as a gear transmission assembly, a pulley transmission assembly, and so on. A specific transmission manner is not limited here, as long as it can be ensured that the motor, when operating, is capable of driving the bottom plate 30 to rotate.

[0125] It should be noted that since the prewashing stage is thefirst started washing stage of the dishwasher, after the detergents are loaded in the first accommodating chamber 1111 and the second accommodating chamber 1112, the drive assembly 40 can drive the bottom plate 30 to open the bottom of the first accommodating chamber 1111 for directly and automatically dispensing the detergent required in the prewashing stage in a quantitative manner.

[01261 In addition, in the implementation illustrated in FIG. 6, the rotating shaft 311 is located on a side of the bottom plate 30, and the bottom plate 30 is rotated about a side of the accommodating chamber 1111 to open the dispensing opening 1113. It can be understood that, in other implementations, the rotating shaft 311 may be located at a middle position of the bottom plate, when the bottom plate 30 is rotated, one portion of the bottom plate 30 is rotated towards the interior of the first accommodating chamber 1111, and the other portion of the bottom plate 30 is rotated towards the exterior of thefirst accommodating chamber 1111. A specific arrangement manner of the rotating shaft 311 is not limited here.

[01271 In addition, it can be understood that, in some implementations, the bottom plate 30 may be slidably arranged on the main body 10, and the drive member 41 is configured to drive, via the transmission member 42, the bottom plate 30 to slide relative to the main body 10, enabling the bottom plate 30 to close or open the dispensing opening 1113.

[01281 In such implementations, transmission via the transmission member 42 can be implemented through a gear and rack transmission mode or a screw and nut mode. For example, a rack portion is arranged on the bottom plate 30 and engages with a gear, and the motor drives the gear to rotate to drive the rack portion to move, thereby driving the bottom plate 30 to move relative to the main body 10. A specific arrangement manner of the transmission member 42 is not limited here.

[0129] In summary, the dispenser 100 according to the implementation of the present

disclosure includes the main body 10, the cover body 20, the bottom plate 30, and the drive

assembly 40. The main body 10 has the first accommodating chamber 1111, the second

accommodating chamber 1112, and the water inlet channel 60 formed therein.

[01301 The second accommodating chamber 1112 and the second accommodating chamber

1112 are arranged in parallel. The first accommodating chamber 1111 has the first opening 1101

located at the top portion of the main body 10 and the dispensing opening 1113 located at the

bottom of the first accommodating chamber 1111, and the second accommodating chamber

1112 has the second opening 1102 located at the top portion of the main body 10. The water

inlet channel 60 is in communication with the second accommodating chamber 1112. The liquid

injected from the water inlet channel 60 into the second accommodating chamber 1112

overflows from the second opening 1102 to be discharged to the outside of the dispenser 100.

The cover body 20 is configured to selectively open or close at least one of thefirst opening

1101 and the second opening 1102.

[01311 The bottom plate 30 is movably arranged on the main body 10. The drive assembly

40 is connected to the bottom plate 30. The drive assembly 40 is configured to drive the bottom

plate 30 to move, enabling the bottom plate 30 to close or open the dispensing opening 1113.

[0132] In the dispenser 100 according to the implementations of the present disclosure, the

drive assembly 40 can drive the bottom plate 30 to open the dispensing opening 1113 for

dispensing the detergent in the first accommodating chamber 1111, such that the dispensing of

the detergent in the first accommodating chamber 1111 can be automatically controlled. In this

case, the operation is simple and the user experience is improved. In addition, the second

accommodating chamber 1112 can contain a sufficient amount of water to dissolve the detergent

in the second accommodating chamber 1112, thereby preventing falling of the solid detergent

into the washing chamber 201 of the washing appliance 1000 and interfering with the normal

operation of the washing appliance 1000.
