Referring to fig. 5 and 6, the bottom of the box body 21 has a water mixing groove 21a, i.e., the water mixing groove 21a is located at the lower portion of the drawing space 2 a.

Referring to fig. 1, fig. 2, fig. 3, fig. 8 and fig. 11, the box cover 22 is provided with a first water inlet passage 220 and a second water inlet passage 221', 221 ″ which are independent from each other, that is, the first water inlet passage 220 and the second water inlet passage 221', 221 ″ are respectively and independently introduced into an external water source, and respectively and independently discharge water without mutual influence. Wherein, the external water source is introduced through the water inlet pipeline.

The water outlet of the first water inlet channel 220 enables the water flow discharged by the first water inlet channel to avoid the distributor box 1 of the detergent dispensing device and to be guided to the box body 21 of the detergent dispensing device. That is, the water flow discharged from the water outlet of the first water inlet passage 220 does not flow through the inside of the dispenser cassette 1.

The outlet of the second water inlet channel 221', 221 "enables the water stream it discharges to enter the dispenser box 1.

That is, for the same second receiving tank 1b, either a detergent container or a hand drop box 33 is placed therein. The user manually puts the amount of detergent required for a single wash into the hand drop box 33.

The detergent container can contain detergent with fluid properties such as laundry detergent, softener, disinfectant fluid and perfume.

For convenience of description, the detergent container placed in the first receiving tank 1a will be referred to as a first detergent container 31, and the detergent container placed in the second receiving tank 1b will be referred to as a second detergent container 32.

The dosing pump is used to pump the detergent in the detergent container placed in the first receiving tank 1a, and/or, to pump the detergent in the detergent container placed in the second receiving tank 1 b.

The water outlet end of the water inlet pipe is connected to the water inlet 220a (refer to fig. 1) of the first water inlet channel 220 or the water inlet 221a ', 221a "(refer to fig. 1) of the second water inlet channel 221', 221" for supplying water to the first water inlet channel 220 or the second water inlet channel 221', 221 ".

For example, in case that water needs to be supplied to the first water inlet channel 220, in some embodiments, the water inlet pipeline is only connected to the water inlet 220a of the first water inlet channel 220, and the water inlets 221a ', 221a "of the second water inlet channels 221', 221" are left empty, i.e., the water inlets 221a ', 221a "of the second water inlet channels 221', 221" are not connected to the water inlet pipeline. In other embodiments, the water inlet 220a of the first water inlet channel 220 is connected to a water inlet pipeline, and the water inlets 221a ', 221a "of the second water inlet channels 221', 221" are connected to another water inlet pipeline, however, only the water inlet pipeline connected to the water inlet 220a of the first water inlet channel 220 is fed, and the water inlet pipeline connected to the water inlets 221a ', 221a "of the second water inlet channels 221', 221" is not fed, that is, the water inlet pipeline connected to the water inlets 221a ', 221a "of the second water inlet channels 221', 221" does not actually work.

In case that water needs to be supplied to the second water inlet channel 221', 221 ", in some embodiments, the water inlet line is only connected to the water inlet 221a ', 221 a" of the second water inlet channel 221', 221 ", and the water inlet 220a of the first water inlet channel 220 is vacant, i.e. the water inlet 220a of the first water inlet channel 220 is not connected to the water inlet line. In other embodiments, the water inlets 221a ', 221a "of the second water inlet channels 221', 221" are connected to a water inlet pipeline, and the water inlet 220a of the first water inlet channel 220 is also connected to another water inlet pipeline, however, only the water inlet pipeline connected to the water inlets 221a ', 221a "of the second water inlet channels 221', 221" is connected to water, and the water inlet pipeline connected to the water inlet of the first water inlet channel 220 is not connected to water, that is, the water inlet pipeline connected to the water inlet 220a of the first water inlet channel 220 does not actually work.

The box cover of the embodiment of the application is provided with the first water inlet channel 220 and the second water inlet channels 221 'and 221' on the same box cover, different positions of water inlet pipelines are configured for different washing equipment, and the water inlet pipelines can be connected as required during assembly.

The detergent feeding device of the embodiment of the application can selectively configure the detergent container or the hand feeding box 33 for the second holding tank according to the model of the washing equipment, namely, the detergent container and the hand feeding box can be interchanged, and the detergent feeding device can be used universally for the washing equipment of different models.

For example, when the configuration model of the washing equipment is the first model, please refer to fig. 8, a first detergent container 31 is placed in the first holding tank 1a, a second detergent container 32 is placed in the second holding tank 1b, the water inlet pipe feeds water to the first water inlet passage 220, and water is not fed to the second water inlet passages 221', 221 ″, during the operation of the washing equipment, the pump is put in to pump the detergent in the first detergent container 31, and the detergent in the second detergent container 32 is pumped, and the detergent is pumped quantitatively by the pump without user intervention. The first model of washing apparatus is configured as an automatic double throw model.

When the configuration model of the washing equipment is the second model, please refer to fig. 11, the first detergent container 31 is placed in the first holding tank 1a, the hand throwing box 33 is placed in the second holding tank 1b, and the water inlet pipe feeds water to the second water inlet channels 221', 221 ″, but does not feed water to the first water inlet channel 220. Thus, the second model of washing device is configured as a combination automatic single dosing and manual dosing model. In this embodiment, a detergent required for washing may be put into the hand drop box 33.

As can be seen from the above, the detergent dispensing device of the embodiment of the present application, and the washing apparatuses with different configurations, may use the same detergent dispensing device, and during assembly, the water inlet pipeline may be connected to the water inlet 220a of the first water inlet channel 220, or connected to the water inlets 221a ', 221a ″ of the second water inlet channels 221', 221 ″, according to the configuration situation of the detergent. Therefore, the generalization rate of parts can be improved, the stock pressure of stagnant materials is reduced, the same mould can be used for manufacturing the detergent feeding device aiming at different configured washing equipment, the cost investment of the mould is reduced, and the product development period can also be shortened.

Exemplarily, in a top view projection of the detergent dispensing device, the water outlet 220a of the first water inlet channel 220 is located outside a projection range of the dispenser box 1. Thus, the water flow discharged from the water outlet 220a of the first water inlet channel 220 does not contact the distributor box 1, and no avoiding hole needs to be formed in the distributor box 1.

The plan projection refers to an orthogonal projection on a horizontal plane from above to below the detergent dispenser. For example, fig. 2 is a top perspective view of the lid.

It can be understood that, when the dispenser box 1 is pushed into the detergent box 2, a right rear corner of the dispenser box 1 has a gap with a rear sidewall of the detergent box 2. For this, the first water inlet passage 220 is exemplarily disposed at the right rear corner of the box cover 22, so that the water flow discharged from the water outlet of the first water inlet passage 220 can be almost vertically dropped onto the bottom wall of the box body 21 without forming an escape hole in the dispenser box 1.

Illustratively, the outlets of the second water inlet passages 221', 221 ″ are disposed at the front of the box cover 22 in the front-rear direction. In this way, the water outlets of the second water inlet channels 221', 221 ″ can be arranged as far forward as possible, so as to facilitate water outlet to the hand drop box 33.

The front in the front-rear direction refers to a front side of the box cover 22 at a half position of a total length in the front-rear direction.

Illustratively, referring to fig. 2, the water inlet 22a of the first water inlet passage 220 and the water inlets 221a ', 221a "of the second water inlet passages 221', 221" are arranged in a staggered manner in the left-right direction. Thus, when the water inlet pipe is connected to the water inlets 221a ', 221a "of the second water inlet passages 221', 221", the water inlet 220a of the first water inlet passage 220 does not interfere with the water inlet pipe, which facilitates installation.

For example, referring to fig. 1, 2 and 3, the box cover 22 has a first spraying outlet 223, and the first spraying outlet 223 is communicated with the first water inlet channel 220, so that part of the water flow in the first water inlet channel 220 is discharged from the first spraying outlet 223.

Referring to fig. 15, the door sealing ring 6 is provided with a spraying opening 6b, the first spraying outlet 223 is communicated with the spraying opening 6b, and water flow sprayed from the spraying opening 6b can flush the door glass of the door body.

Illustratively, referring to fig. 1, 2 and 3, the box cover 22 has a second spray outlet 224, and the second spray outlet 224 is communicated with a second water inlet channel 221', 221 ", so that part of the water in the second water inlet channel 221', 221" is discharged from the second spray outlet 224. The second spray outlet 224 communicates with the spray port 6b of the door seal 6.

It should be noted that the first spraying outlet 223 and the second spraying outlet 224 may be respectively connected to the spraying port 6b through independent pipelines, or may be connected to the spraying port 6b through a shared part of pipelines.

Referring to fig. 12, the hand drop box 33 has drop chambers 33a ', 33a ", the top sides of the drop chambers 33a ', 33 a" have drop ports 33b ', 33b ", and the drop ports 33b ', 33 b" are used for receiving the water flow of the second water inlet channels 221', 221 ". The water outlet of the second water inlet channel 221', 221 "is aligned with the drop port 33b ', 33 b", and the water flow discharged from the water outlet of the second water inlet channel 221', 221 "naturally falls into the drop port 33b ', 33 b" and into the drop chamber 33a ', 33a ".

It should be noted that the water flow in the dosing chambers 33a', 33a "is finally collected in the mixing tank 21 a.

The number of the second water inlet passages 221', 221 ″ may be one, two, or more. The number of dosing chambers 33a ', 33a "is the same as the number of second inlet channels 221', 221", one second inlet channel 221', 221 "discharging water to a corresponding one of the dosing chambers 33a', 33 a".

Illustratively, referring to fig. 1, fig. 2, and fig. 3, the number of the second water inlet channels 221', 221 "is at least two, and each of the second water inlet channels 221', 221" is independent from each other, i.e. the water flows in each of the second water inlet channels 221', 221 "do not cross each other. For example, when water is required to be supplied to the second water inlet passages 221', 221 ″, the number of the water inlet pipes is at least two, one of the water inlet pipes is connected to the water inlet 221a ' of one of the second water inlet passages 221', and the other water inlet pipe is connected to the water inlet 221a ″ of the other of the second water inlet passages 221 ″.

The water outlets of the respective second water inlet passages 221', 221 ″ are arranged in a staggered manner to independently discharge water to different portions of the respective second accommodating grooves 1 b.

Accordingly, referring to fig. 12, the hand drop box 33 has at least two drop chambers 33a ', 33a ", wherein the water outlet of one second water inlet channel 221' is connected to one drop port 33b ' and the water outlet of the other second water inlet channel 221" is connected to the other drop port 33b ".

Exemplarily, referring to fig. 2, the water inlets 221a ', 221a "of the respective second water inlet channels 221', 221" are arranged in a staggered manner in the left-right direction. Thus, when the water inlet pipes are connected to the water inlets 221a ', 221a ″ of the corresponding second water inlet channels 221', 221 ″, the water inlet pipes are arranged side by side along the left-right direction, which is convenient for pipe arrangement and avoids excessively influencing the size of the box cover 22 in the height direction.

Illustratively, the outlets of the second water inlet channels 221', 221 ″ are staggered in the front-rear direction. Accordingly, referring to fig. 12, 13 and 14, each of the throwing chambers 33a ', 33a ″ is arranged in the front-rear direction, the rear side of the rearmost throwing chamber 33a' is opened, and the water flow entering the rearmost throwing chamber 33a 'flows out of the dispenser box 1 from the opened rear side and flows toward the water mixing tub 21a, and in this embodiment, washing powder, laundry detergent, etc. may be thrown into the rearmost throwing chamber 33 a'.

Referring to fig. 14, the front dosing chamber 33a "is connected to the adjacent rear dosing chamber 33a' by a siphon channel 33 c. The front dispensing chamber 33a ″ can store fluid detergent for nursing such as softener. In this way, the liquid in the hand drop box 33 is discharged only from the rear opening of the rearmost drop chamber 33a', and the structure is simple.

The rearmost drop chamber means the one of the drop chambers 33a', 33a ″ that is closest to the rear.

The forward-located dosing chambers are all the other dosing chambers 33a ', 33a ″ except the rearmost dosing chamber 33a' described above.

For example, when the number of the dispensing chambers is two, the rear one of the dispensing chambers is the rearmost dispensing chamber 33a', and the foremost one of the dispensing chambers 33a "is the foremost dispensing chamber 33 a".

For another example, when the number of the throwing chambers is three, the middle throwing chamber and the foremost throwing chamber are both the front throwing chamber, wherein the foremost throwing chamber 33a ″ is communicated with the middle throwing chamber through the siphon channel 33c, and the middle throwing chamber is communicated with the rearmost throwing chamber through the other siphon channel 33 c.

Illustratively, the rear side of each holding tank is open, so that the bottle mouth of the detergent container is directly or indirectly matched with the feeding pump in a plugging mode.

Illustratively, the first and second receiving tanks 1a and 1b are the same in size for receiving detergent containers having the same external dimensions. That is, the first detergent container 31 and the second detergent container 32 have substantially the same outer dimensions, so that the detergent containers can be easily manufactured using substantially the same molds, thereby reducing the cost.

Referring to fig. 5, the rear side wall of the box body 2 is provided with at least two avoiding openings 21d ', 21d "and at least two detergent liquid inlets 21f ', 21 f", each detergent container corresponds to one avoiding opening 21d ', 21d ", each avoiding opening 21d ', 21 d" is used for avoiding direct or indirect plug-in cooperation between the corresponding detergent container and the liquid suction opening of the dosing pump 5, and the detergent liquid inlets 21f ', 21f "are used for guiding the detergent discharged by the dosing pump 5 to the water mixing tank 21 a.

That is, the escape openings 21d', 21d ″ do not interfere with the process of directly or indirectly inserting and removing the detergent container from and from the liquid suction opening of the dispensing pump 5.

Illustratively, the dispenser cassette 1 has a plurality of pairs of position-limiting structures, wherein one pair of position-limiting structures is provided in the first receiving groove 1a, and the other pair of position-limiting structures is provided in the second receiving groove 1 b.

Each pair of the position-limiting structures includes a position-limiting protrusion 11 (see fig. 7, 10, and 14) and an elastic arm 12 (see fig. 10 and 14), the elastic arm 12 is disposed at an open position at the rear side of the receiving groove, a first end of the elastic arm 12 is a fixed end, and a second end of the elastic arm 12 is a free end.

Referring to fig. 10 and 14, the limiting protrusion 11 protrudes from the front sidewall of the receiving groove, the elastic arm 12 can be elastically deformed under the action of the detergent container, and the elastic arm 12 and the limiting protrusion 11 are at least used for restraining the detergent container therebetween.

When the detergent container is installed, the rear end of the detergent container presses the elastic arm 12 to force the elastic arm 12 to deform backwards, the front end of the detergent container is pressed against the limiting protrusion 11, the detergent container is loosened, the detergent container is pressed against the limiting protrusion 11 by the elastic arm 12, and therefore the detergent container is installed and positioned.

The specific configuration of the resilient arm 12 is not limited, for example, in some embodiments, the resilient arm 12 may be a metal sheet or wire that fits over the dispenser box 1. In other embodiments, the latch arm 12 is formed as part of the unitary structure of the dispenser cassette 1 and is injection molded together during the molding process.

The limiting protrusion 11 is formed in an unlimited manner, for example, in some embodiments, a separate component is installed on the front sidewall of the receiving groove, and the component defines the limiting protrusion 11.

In other embodiments, referring to fig. 10 and 14, the limiting protrusion 11 is formed by partially recessing the front sidewall of the receiving groove, and the wall thickness of the limiting protrusion 11 is smaller than the wall thickness of the structure around the limiting protrusion 11. The position of the limiting protrusion 11 is designed to be a thin wall, so that the limiting protrusion 11 can be elastically deformed slightly under the action of external force.

It should be noted that, in some embodiments, the hand drop box 33 is limited by the pair of limiting structures located in the second receiving groove 1b, that is, the pair of limiting structures located in the second receiving groove 1b can be reused.

In other embodiments, the hand drop box 33 is not limited by the above-mentioned limiting structure. Specifically, the rear end of the hand throw box 33 abuts against the flange structure around the rear side of the second accommodation groove 1b, the front end of the hand throw box 33 abuts against the above-mentioned limit projection 11, and the hand throw box 33 is clamped between the flange structure and the limit projection 11 by slight deformation of the limit projection 11. Since the user does not need to frequently take out the hand drop box 33 after the complete machine is assembled, the hand drop box 33 is relatively tightly assembled, but the user can take out the hand drop box 33 even if the user exerts a little force.

For example, referring to fig. 15, the washing apparatus includes a first water outlet passage 41. The door seal 6 has a water filling port 6 a. Referring to fig. 6, the case body 21 has a first drain port 21b communicating with the water mixing tank 21a, and the first water outlet passage 41 communicates the first drain port 21b and the water injection port 6 a. That is, the water in the water mixing tank 21a is injected into the inner tub through the first water outlet path 41 and the water injection port 6a of the door seal 6, so that the detergent is directly injected into the inner tub and directly contacts with the clothes, and the utilization rate of the detergent is improved.

Illustratively, in some embodiments, the inner barrel is provided with lifting ribs. The area of the inner barrel covered by the lifting ribs is provided with water holes, the inner barrel is located outside the area covered by the lifting ribs and is not provided with water holes, and water liquid exchange is carried out between the inner barrel and the water containing barrel through the water holes. In this embodiment, the laundry does not contact with the hole edges of the water passing holes, and the wear of the laundry by the hole edges of the water passing holes can be reduced.

In the embodiment that the door sealing ring 6 is provided with the water filling port 6a, water liquid directly enters the inner barrel, and the water filled into the inner barrel slowly enters the water containing barrel through the water holes, so that clothes can be soaked as soon as possible, and the washing efficiency is improved.

For example, referring to fig. 5 and 6, the box body 21 has a second water outlet 21c, and when the water level in the water mixing tank 21a is higher than the predetermined water level, the liquid in the water mixing tank 21a overflows to the second water outlet 21 c. Referring to fig. 15, the washing apparatus includes a second water outlet passage 42, and the second water outlet passage 42 serves to guide the water flow discharged from the second water discharge port 21c between the tub and the inner tub.

In this embodiment, when the water level in the water mixing tub 21a is not higher than the overflow water level, the water in the water mixing tub 21a enters the first water outlet passage 41 from the first drain port 21 b. When the water level in the water mixing tub 21a is higher than the overflow water level, the excess water overflows to the second water discharge port 21c and enters the second water outlet passage 42. Since the first outlet passage 41 needs to be guided to the water filling port 6a of the door seal 6, the maximum water flow is limited by the water filling port 6 a. The second water outlet 21c and the second water outlet passage 42 can guide the water flow to the water containing barrel in time under the condition of overflow, thereby not only playing a role of safety protection, but also accelerating water inlet.

For example, in some embodiments, referring to fig. 5 and 6, the bottom wall of the box body 21 is provided with a water blocking rib 211, the water mixing tank 21a and the first water discharge port 21b are located on a first side of the water blocking rib 211, and the second water discharge port 21c is located on a second side of the water blocking rib 211. The height of the top edge of the water-blocking rib 211 is used as the overflow water level of the water mixing tank 21a, and when the water level in the water mixing tank 21a continuously rises to the top edge of the water-blocking rib 211, water flows over the water-blocking rib 211, flows to the second side of the water-blocking rib 211 from the top side of the water-blocking rib 211, and is discharged from the second water outlet 21 c.

In the embodiment of the present invention, the detergent container may be placed in the holding tank after being purchased by the user, or may be placed in the holding tank at the time of shipment. When the hand drop box 33 needs to be arranged, the hand drop box 33 is installed in the second accommodation groove 1b when the complete machine is shipped. The user can take out the hand drop box 33 as necessary for use and clean it, and then put it into the second housing groove 1 b.

The water inlet of the second circulation path 83 is connected to the water outlet of the filter container 34 to return the water filtered by the filter container 34 to the water tub or the inner tub.

In this embodiment, the circulating pump 81 pumps the water with the lint from the bottom of the tub to the water inlet of the filtering container 34, the lint is retained in the filtering container 34 after passing through the filtering container 34, and the filtered water flows out through the water outlet of the filtering container 34, so as to achieve the purpose of circulating and filtering the lint.

In some embodiments, the filtering container 34 may further include modules for scale inhibition, sterilization, aroma, and the like, so as to achieve the functions of color protection, sterilization, aroma enhancement, and the like.

It is understood that, in some embodiments, the second circulation path 83 may directly discharge the water drained from the filtering container 34 into the inner tub or the tub.

In other embodiments, referring to fig. 15, the water outlet end of the second circulation path 83 is connected to the first water outlet path 41, that is, the second circulation path 83 connects the water outlet of the filter container 34 and the first water outlet path 41. The water in the second circulation path 83 flows into the inner cylinder through the first water outlet path 41 and the water inlet 6 a. That is, the first drain port 21b and the second circulation passage 83 are both communicated with the first water outlet passage 41, so that the first water outlet passage 41 can be reused, and the structure is compact.

For example, referring to fig. 4 and 6, a three-way structure 212 is disposed below the box body 21, a first port of the three-way structure 212 is used as the first drainage port 21b, a water outlet end of the second circulation path 83 is connected to the second port, and a water inlet end of the second water outlet path 42 is connected to the third port.
