Detailed Description

Embodiments of the present application will be described in further detail below with reference to the drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.

In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the embodiments of the present application and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An embodiment of the present invention provides a detergent dispensing device 100 for a washing apparatus, referring to fig. 1 and 2, including a dispenser box 10 and a detergent box 20, wherein the dispenser box 10 is drawably disposed in the detergent box 20. In which the drawing direction of the dispenser cassette 10 is the front-rear direction in fig. 1.

Referring to fig. 1, the dispenser case 10 is in a state of being withdrawn from the detergent case 20. During normal use of the washing apparatus, the dispenser box 10 is pushed into the detergent box 20.

Referring to fig. 12, 13 and 14, the embodiment of the present application further provides a washing apparatus, including an inner barrel 82, an outer barrel 81, and a detergent dispensing device 100 according to any embodiment of the present application. The inner cylinder 82 is disposed in the outer cylinder 81.

The specific type of the washing device is not limited, and may be, for example, a washing machine, a washing and drying machine, or the like.

For example, referring to fig. 2, the detergent box 20 includes a box body 21 and a box cover 22. The top side of the box body 21 is opened, and the box cover 22 is arranged on the top side of the box body 21.

Referring to fig. 6, 7 and 11, the box body 21 is provided with an air pressure balancing port 21g. The outer barrel is provided with a vent. The washing device comprises an air pressure balancing pipeline which is communicated with the air vent and the air pressure balancing port 21g. The space in the outer barrel keeps air pressure balance with the space in the detergent box through the air pressure balance pipeline, and the space in the detergent box is communicated with the external environment, so that the air pressure in the detergent box is the same as the external atmospheric pressure, and therefore, the air pressure balance between the outer barrel and the atmospheric environment can be realized.

It should be noted that, if the outer barrel has no vent, the space in the outer barrel is in a relatively closed state, and a certain air pressure is generated, and the air pressure will generate a certain back pressure to the water inlet process of the outer barrel and/or the inner barrel, so that water cannot enter or water slowly enters.

It should be noted that, in the related art, the water in the detergent box is easily splashed into the air pressure balancing pipeline from the air pressure balancing port, so that the water seepage phenomenon is easily caused at the connection position of the air pressure balancing port and the air pressure balancing pipeline.

For example, referring to fig. 4 and 5, the detergent box 20 includes a water blocking member 221, and the water blocking member 221 is disposed inside the air pressure balancing port 21g and blocks the air pressure balancing port 21g. Wherein, the inside means a side of the air pressure balancing port 21g facing the inner space of the detergent box 20.

The shielding of the air pressure balancing port 21g means that the first water blocking wall 2211 shields the air pressure balancing port 21g in a plane projection perpendicular to a normal direction of the air pressure balancing port 21g. The water stopper 221 does not block the air pressure equalizing port 21g, and does not affect ventilation of the air pressure equalizing port 21g.

The detergent box 20 of this application embodiment, the fender water spare 221 plays the effect of sheltering from to the balanced mouthful 21g of atmospheric pressure, and the splash that splashes in the detergent box 20 is difficult for splashing to the outside of detergent box 20 from the balanced mouthful 21g of atmospheric pressure for the difficult infiltration phenomenon that takes place in the takeover position of the balanced mouth of atmospheric pressure and the balanced pipeline of atmospheric pressure.

The specific location of the air pressure balancing port 21g is not limited, for example, in some embodiments, the air pressure balancing port 21g may be disposed on the sidewall of the box body 21 along all directions; referring to fig. 6 and 11, in other embodiments, the air pressure balancing port 21g is disposed on the rear wall of the box body 21, so as to facilitate connection and arrangement of the air pressure balancing pipe. Referring to fig. 6 and 9, the bottom of the box body 21 has a water mixing tank 21a and a first drain port 21b communicated with each other, and the first drain port 21b is used for draining water in the water mixing tank 21a. The detergent and the water flow toward the mixing tub 21a, and the water flow carries the detergent to be discharged from the first drain port 21 b.

The washing apparatus exemplarily includes a door, a cabinet, and a door sealing ring 50 (refer to fig. 12) provided at a front end of the inner tub 82, and the outer tub 81 is provided in the cabinet. The box is provided with the opening, and the door body is used for opening or closing the opening. When the door closes the opening, the door sealingly abuts against the door seal 50.

For example, referring to fig. 12 and 14, the door seal 50 has a water filling port 50a. Referring to fig. 13 and 14, the washing apparatus includes a first water outlet pipe 71, and the first water outlet pipe 71 communicates the first water outlet 21b and the water inlet 50a. That is, the water in the water mixing tank 21a flows through the first water outlet 21b and the water inlet 50a of the door sealing ring 50 and is injected into the inner drum 82, so that the detergent directly rushes into the inner drum 82 and directly contacts with the clothes, and the utilization rate of the detergent is improved.

Illustratively, in some embodiments, the inner barrel 82 is provided with lifting ribs. The area of the inner cylinder 82 covered by the lifting ribs is provided with water through holes, the inner cylinder 82 is not provided with water through holes outside the area covered by the lifting ribs, and water and liquid exchange is carried out between the inner cylinder 82 and the outer cylinder 81 through the water through holes. In the embodiment, the clothes do not contact with the hole edges of the water through holes, so that the abrasion of the hole edges of the water through holes to the clothes can be reduced. In this embodiment, the water directly enters the inner barrel 82, and the water injected into the inner barrel 82 slowly enters the outer barrel 81 through the water holes, so as to soak the clothes as soon as possible and improve the washing efficiency.

For example, referring to fig. 4 and 5, the top end of the water blocking member 221 is connected to the top wall of the box cover 22, and the bottom end of the water blocking member 221 is spaced from the bottom wall of the box body 21. Thus, during the assembling process of the box cover 22 and the box body 21, the bottom end of the water blocking member 221 will not interfere with the box body 21, and the water flow along the bottom wall of the box body 21 will not be affected.

Illustratively, the water stop 221 and the cover 22 are integrally injection molded plastic parts.

For example, referring to fig. 6, a drawing space 21k for drawing the dispenser box 10 and a narrowing space 21s disposed at the right rear side of the drawing space 21k are provided in the box body 21, and an air pressure balancing port 21g is disposed on a rear wall of the narrowing space 21 s.

The lower end of the water deflector 221 protrudes into the narrowed space 21 s. Thus, the water blocking member 221 does not interfere with the drawing operation of the dispenser box 10, and the side wall of the narrowing space 21s in the left-right direction can also perform a good water blocking function for the air pressure balancing port 21g, and the water blocking member 221 only needs to block water from the front side of the air pressure balancing port 21g.

The width of the narrowing space 21s in the left-right direction is smaller than the drawing space, for example, less than 1/4 of the width of the drawing space.

For example, referring to fig. 1 and 2, the top wall of the box cover 22 is provided with a water inlet 22a, the water inlet 22a is communicated with the space inside the detergent box 20, and water can enter the detergent box 20 from the water inlet 22a and flow to the water mixing tank 21a along the bottom wall of the box body 21.

Illustratively, the water inlet 22a is disposed at a position of the box cover 22 above the narrowing space 21s, and water flowing from the water inlet 22a flows to the bottom wall of the narrowing space 21s, and then flows along the bottom wall of the narrowing space 21s to the bottom wall of the drawing space and further flows into the water mixing tank.

Referring to fig. 5, the water blocking member 221 includes a first water blocking wall 2211, a front surface of the first water blocking wall 2211 is used for guiding water from the water inlet 22a to the bottom wall of the box body 21, and water flows to the water mixing tank 21a along the bottom wall of the box body 21. The first water-blocking wall 2211 blocks the air pressure balance port 21g.

In this embodiment, the first water blocking wall 2211 not only has the function of shielding the air pressure balancing port 21g, but also has the function of guiding water at the water inlet 22a, so as to reduce the impact force of water flow impacting the bottom wall of the box body 21 and reduce noise generated by water flow impact; in addition, the degree of splash sputtering can also be reduced.

It should be noted that the water inlet 22a may introduce various water sources, for example, in some embodiments, the water inlet line 72 is connected to the water inlet 22a for introducing an external water source, such as tap water. In other embodiments, the water inlet 22a introduces circulating water from the outer drum and/or the inner drum.

The specific structure of the water blocking member 221 is not limited, for example, the water blocking member 221 is in a sheet shape, and water flows from top to bottom along the water guiding surface on the front side of the first water blocking wall 2211. In some embodiments, the first water-blocking wall 2211 is inclined forward gradually in the top-down direction, so that the water flow is facilitated to flow along the water-guiding surface. Of course, the water guide surface may not be inclined.

For example, referring to fig. 5, the water blocking member 221 includes a second water blocking wall 2212 located at a front side of the first water blocking wall 2211, and the first water blocking wall 2211 and the second water blocking wall 2212 define the diversion flow passage 221a. Illustratively, the left end of first water-blocking wall 2211 is connected to the left end of second water-blocking wall 2212, and the right end of first water-blocking wall 2211 is connected to the right end of second water-blocking wall 2212, which define a flat diversion channel 221a, i.e. water-blocking member 221 is in the shape of a flat tube.

The water flows in the diversion flow channel 221a, and the diversion flow channel 221a can better restrict and divert the water flow, so that the degree of splashing of the water flow to the periphery is reduced.

Exemplarily, referring to fig. 3 and 5, the bottom edge of second water blocking wall 2212 is lower than the bottom edge of first water blocking wall 2211. In this embodiment, the length of the second water blocking wall 2212 in the vertical direction is smaller than the length of the first water blocking wall 2211 in the vertical direction, so that the cantilever length of the mold of the water blocking member 221 can be reduced, the stress condition of the mold can be improved, and the service life and reliability of the mold can be improved.

For example, referring to fig. 5, an opening groove 2212a is formed in the second water blocking wall 2212, and the opening groove 2212a extends in the up-and-down direction and penetrates through the bottom edge of the second water blocking wall 2212.

The open slot 2212a can also be modified to the stress condition of the mold. Specifically, the mold is provided with a mold core at the opening slot 2212a, and the mold core and the mold part corresponding to the first water blocking wall 2211 can be connected together, so that the mold part corresponding to the first water blocking wall 2211 can be prevented from being in a thin and long cantilever state, so that the stress condition of the mold can be improved, and the service life and reliability of the mold can be improved.

Exemplarily, the water stopper 221 is located at the rear of the detergent box 20. The water blocking member 221 does not interfere with the drawing motion of the detergent box 20.

Illustratively, referring to fig. 10, the dispenser cartridge 10 has a first receiving groove 10a for mounting the filter 31, and the water blocking member 221 is disposed behind the first receiving groove 10a, that is, the water blocking member 221 is disposed behind the filter 31. The rear of the filter 31 does not need to arrange the components of the dosing pump 40, and a spacious space is provided to make full use of the space to arrange the water blocking member 221.

Referring to fig. 6 and 9, the bottom wall of the box body 21 is provided with a water blocking rib 211 and a second drain opening 21d, and the water blocking rib 211 partitions the lower space of the detergent box 20 out of the mixing tub 21a and the drain tub 21c. The second drain port 21d communicates with the drain groove 21c, and the second drain port 21d is used for draining the water in the drain groove 21c. That is, the first drain port 21b and the water mixing groove 21a are located at one side of the water blocking rib 211, and the second drain port 21d and the water mixing groove 21c are located at the other side of the water blocking rib 211.

For example, referring to fig. 12, the washing apparatus includes a second water outlet pipe 74, and the second water outlet pipe 74 guides the water flow discharged from the second water outlet 21d to between the outer tub 81 and the inner tub 82.

It is understood that the water flow sectional area of the second drain port 21d is larger than that of the first drain port 21 b. That is, when the amount of water is equally sufficient, the flow rate of water discharged from the second drain port 21d is larger than that of water discharged from the first drain port 21 b.

When the water level in the water mixing tank 21a is higher than the overflow water level, the liquid in the water mixing tank 21a overflows to the drain tank 21c.

In this embodiment, when the water level in the water mixing tank 21a is not higher than the overflow water level, the water in the water mixing tank 21a enters the first water outlet pipeline 71 from the first water outlet 21 b. When the water level in the mixing tank 21a is higher than the overflow water level, the excess water overflows into the drain tank 21c and enters the second outlet pipe 74 through the second outlet port 21 d. That is, the detergent dispenser 100 preferentially discharges water from the first drain port 21 b.

Since the water of the first drain port 21b needs to be guided to the water filling port 50a of the door seal 50, the maximum water flow is limited by the water filling port 50a. The second water outlet 21d and the water discharge groove 21c can guide the water flow in the detergent box 20 to the outer tub 81 in time under the overflow condition, thereby not only performing the safety protection function, but also accelerating the water inflow.

The overflow water level in the water mixing tank 21a is determined by the structure of the water blocking rib 211, and specifically, the overflow water level is the lowest water level at which the water blocking rib 211 allows the water in the water mixing tank 21a to flow to the drainage tank 21c.

Illustratively, in some embodiments, the height of the top edge of the water-blocking rib 211 is used as the overflow water level of the water mixing groove 21a, and when the water level in the water mixing groove 21a continuously rises to the top edge of the water-blocking rib 211, the water liquid flows over the water-blocking rib 211, flows into the water discharge groove 21c on 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 discharge opening 21 d.

In other embodiments, the water blocking rib 211 is provided with a gap, and the height of the bottom edge of the gap is used as the overflow water level of the water mixing tank 21a.

Referring to fig. 7, 8 and 9, the detergent dispensing device 100 includes a venturi tube 23 disposed below the detergent box 20, for example. Referring to fig. 12, the washing apparatus includes a water inlet pipeline 72, an inlet 23a (see fig. 9) of the venturi 23 is used for connecting the water inlet pipeline 72, and a first water outlet 21b is connected to a negative pressure suction port 23c (see fig. 9) of the venturi 23; the first water outlet line 71 is connected to the outlet 23b (see fig. 9) of the venturi tube 23.

When water enters, water from the water inlet pipeline 72 flows through the venturi tube 23, negative pressure is generated at the negative pressure suction port by the water flow, and water at the first water outlet 21b is sucked into the venturi tube 23, converged into the first water outlet pipeline 71, and flows to the water filling port 50a of the door sealing ring 50.

In this embodiment, the venturi tube 23 can accelerate the water discharge speed of the water mixing tank 21a so that the water in the water mixing tank 21a is discharged from the first water discharge port 21b as much as possible, that is, the water mixed with the detergent can enter the inner cylinder 82 from the water injection port 50a of the door seal 50 as much as possible and overflow into the water discharge tank 21c as little as possible.

Illustratively, referring to fig. 2, the detergent dispensing device 100 includes a dispensing pump 40, and the dispensing pump 40 is used for pumping the detergent in the dispenser box 10. It should be noted that the detergent in the dispenser box 10 may be the detergent directly stored in the accommodating cavity of the dispenser box 10, or the detergent in the detergent bottle 32 placed in the dispenser box 10.

In the embodiment of the present application, the detergent in the detergent bottle 32 is pumped by the feeding pump 40.

Referring to fig. 3 and 6, at least one feeding port 21f is formed on the rear wall of the box body 21, wherein the number of the feeding ports 21f is the same as the number of the suction ports of the feeding pump 40, and the number of the detergent bottles 32. The detergent is drawn into the dosing pump 40 from the suction port of the dosing pump 40, and is dosed into the detergent box 20 from the dosing port 21 f.

Illustratively, referring to fig. 1, 2 and 3, the top wall of the box cover 22 is provided with at least one flushing port connector 22b, and the flushing port connector 22b is positioned above the input port 21 f. Referring to fig. 12, the washing apparatus includes at least one water inlet branch pipe 73, one end of each water inlet branch pipe 73 is communicated with the water inlet pipe, the other end of the water inlet branch pipe 73 is connected with a corresponding wash port connector 22b, and the wash port connector 22b is used to guide the water of the water inlet branch pipe 73 to the inside of the detergent box 20.

When the water inlet pipeline 72 is fed with water, the water path entering the water inlet pipeline 72 is divided into multiple paths, wherein one path flows to the venturi tube 23 through the downstream of the water inlet pipeline 72, and the other path flows to the inside of the detergent box 20 through the water inlet branch pipe 73 and the flushing port connector 22b, flushes the detergent below the feeding port 21f, and carries the detergent to flow to the water mixing tank 21a.

The water flowing down from the flushing port connector 22b has a flushing effect on the detergent, so that the detergent is dissolved favorably, the probability of the detergent remaining on the inner wall of the box body 21 is reduced, and the probability of bacterial growth is reduced.

Illustratively, referring to FIG. 10, the dispenser box 10 has at least one second receiving groove 10b, the second receiving groove 10b receiving a detergent bottle 32.

For example, referring to fig. 1 and 10, the first receiving grooves 10a and the second receiving grooves 10b are arranged side by side along the left-right direction.

The detergent bottle 32 may contain detergents such as laundry detergent, softener, disinfectant fluid, perfume, etc. In an embodiment having a plurality of detergent bottles 32, each detergent bottle 32 may store therein different kinds of detergent.

Referring to fig. 14 and 15, the detergent box 20 is provided with a circulating water joint 24, the circulating water joint 24 includes a circulating water channel 241a and a circulating water standby channel 242a which are mutually communicated, an outlet of the circulating water channel 241a is used for being plugged and matched with a water inlet 22a of the filter 31 in the distributor box 10, and an inlet of the circulating water channel 241a is used for introducing circulating water. Specifically, the circulation pump 61 is used to pump the water in the outer tub 81 to the inlet of the circulation water channel 241a via the circulation line 62.

The circulating pump 61 pumps the water with the flocks at the bottom of the outer barrel 81 to the inlet of the circulating water channel 241a, the circulating water enters the filter 31 through the circulating water channel 241a, the flocks are left in the filter 31 after flowing through the filter 31, and the filtered water flows out from the water outlet of the filter 31, so that the aim of circularly filtering the flocks is fulfilled.

The highest position of the circulating water backup passage 242a is higher than that of the circulating water passage 241 a. In this way, after the water flow enters the circulating water channel 241a from the inlet of the circulating water channel 241a, the resistance of the water flow flowing through the circulating water channel 241a to the filter 31 is smaller than the resistance of the water flow flowing to the circulating water standby channel 242a, so that the circulating water flows preferentially to the filter 31 through the circulating water channel 241a in the normal use state.

When the filter 31 is clogged, the back pressure of the outlet of the circulating water passage 241a increases, and the circulating water is forced to flow to the circulating water backup passage 242a and is discharged through the circulating water backup passage 242a. Therefore, the circulating water standby passage 242a plays a safety precaution role, and can drain water in the circulating pipeline 62 in time when the filter 31 is blocked, so that the probability of faults such as pipe explosion, damage to the circulating pump 61 and the like caused by rapid increase of water pressure is reduced.

Illustratively, the water mixing tank 21a is configured to receive filtered water filtered by the filter 31. That is to say, the water filtered by the filter 31 directly flows to the water mixing tank 21a below the filter 31 without providing an additional pipeline for draining, and the first drain port 21b is reused for draining, so that the structure can be simplified, and the structure of the detergent putting device 100 is simpler.

It should be noted that the outlet of the circulating water backup passage 242a can direct the flow of water to any suitable location. For example, in some embodiments, the water at the water outlet of the circulating water standby passage 242a is directly returned to the outer tub 81 through a pipeline.

In other embodiments, the water outlet of the circulating water backup passage 242a is communicated with the water mixing tank 21a, that is, the water mixing tank 21a is also used for receiving water from the circulating water backup passage 242a, so that an additional pipeline does not need to be arranged to connect the water outlet of the circulating water backup passage 242a, and the first water outlet 21b is used for draining water, which can simplify the structure and make the structure of the detergent dispensing device 100 simpler.

For example, referring to fig. 12 and 14, a circulating water joint 24 is disposed at the rear of the detergent box 20. The circulating water joint 24 includes a main pipeline 241 and a branch pipeline 242 which are connected with each other, the main pipeline 241 is arranged along the front-back direction, the back end of the main pipeline 241 is used for connecting with the circulating pipeline 62, and the front end of the main pipeline 241 is used for being matched with the water inlet 22a of the filter 31 in a plugging manner.

Illustratively, referring to fig. 3, the rear wall of the box 21 is provided with an avoiding opening 21h, and the front end of the main pipeline 241 extends into the box 21 through the avoiding opening 21 h.

The flow passage in the main pipe 241 defines the circulation water passage described above, and the space in the branch pipe 242 defines the circulation water backup passage 242a described above.

When the dispenser cassette 10 is withdrawn, the front end of the main pipeline 241 is separated from the filter 31, and when the dispenser is pushed into place, the front end of the main pipeline 241 and the filter 31 are inserted into place.

One end of branch pipe 242 is connected to main pipe 241, for example, a tee is provided at the connection between the two. The other end of the branch pipe 242 is wound around the top side of the box cover 22 from the rear of the box body 21 and connected to the water inlet 22 a. Thus, the branch pipe 242 does not occupy the space inside the detergent box 20, facilitating pipe distribution and making the detergent box 20 compact.

It should be noted that main pipeline 241 may be a complete pipeline, or may be formed by connecting a plurality of segmented pipelines.

The branch pipe 242 may be a complete pipe or may be formed by connecting a plurality of sectional pipes.

Referring to fig. 1 and 2, the box cover 22 is provided with a hand-throwing water inlet passage 22c for introducing an external water source, and a water outlet of the hand-throwing water inlet passage 22c is positioned above the second receiving groove 10b so that water discharged from the hand-throwing water inlet passage can enter the dispenser box 10. That is, the water flow discharged from the hand-throwing water passage 22c flows into the dispenser box 10 and then flows from the dispenser box 10 to the water mixing tank 21a.

The at least one second receiving groove 10b is for receiving a detergent bottle 32 or a hand drop box. That is, for the same second receiving groove 10b, either the detergent bottle 32 or the hand-drop box is placed therein. The design of the detergent dispensing device 100 is such that the detergent container and the hand-operated dispenser can be interchanged.

The user manually puts the dosage of the detergent required by single washing into the hand throwing box. When the hand drop box is placed in the second accommodating groove 10b, the water inlet pipeline 72 is connected to the water inlet 22a of the hand drop water inlet channel 22c, and the water flow discharged by the hand drop water inlet channel 22c flows into the hand drop box to carry the detergent in the hand drop box to flow to the water mixing groove 21a.

The detergent dispenser 100 of this embodiment, which selectively configures the detergent bottle 32 or the hand-throw box, can use the same detergent dispenser 100 for different configurations of washing apparatuses, and during the assembly, the water inlet pipe 72 can be connected to the water inlet 22a of the hand-throw water passage 22c or to the inlet of the venturi 23 according to the configuration 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 100 aiming at different configured washing equipment, the cost investment of the mould is reduced, and the product development period can also be shortened.

In the embodiment where the number of the second receiving grooves 10b is at least two, one of the second receiving grooves 10b may receive a hand drop box, and the other second receiving groove 10b may receive a detergent bottle 32; alternatively, all the second accommodation grooves 10b accommodate the detergent bottles 32; alternatively, all the second accommodation grooves 10b accommodate the hand-throw cartridges.
