The application embodiments and simplified descriptions do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the embodiments of the 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.

The embodiment of the present application provides a detergent dispensing device 100 for use in washing equipment. Please refer to FIGS. 1 and 2 , including a dispenser box 10 and a detergent box 20 .

The embodiment of the present application also provides a washing equipment, please refer to Figure 11, Figure 12 and Figure 13 in conjunction, including an inner barrel 90, an outer barrel 80, a circulation pump 61, a circulation pipeline 62 and the detergent delivery of any embodiment of the present application. Device 100.

The inner cylinder 90 is disposed in the outer bucket 80 , and the inner cylinder 90 contains water through the outer bucket 80 .

The specific type of washing equipment is not limited, for example, it can be a washing machine, an all-in-one washing and drying machine, etc.

The distributor box 10 has an installation space for installing the filter 31 . The filter 31 is installed in the installation space. The specific type of the installation space is not limited. For example, in some embodiments, please refer to FIG. 10 , the installation space is configured in the form of a receiving groove 10 a, and the filter 31 is disposed in the receiving groove 10 a.

Referring to FIGS. 3 and 12 , the detergent box 20 has a pull-out space 20 a, and the dispenser box 10 is pullably disposed in the pull-out space 20 a in the detergent box 20 . Referring to FIG. 1 , the dispenser box 10 is in a state of being extracted from the drawing space 20 a. During normal use of the washing equipment, the dispenser box 10 is pushed into the pull-out space 20a.

Referring to Figures 6 and 9, the detergent box 20 has an interconnected mixing tank 21a and a first drain port 21b. The first drain port 21b is used to discharge water in the mixing tank 21a. Specifically, the mixing tank 21a is located at the lower part of the pull-out space 20a. The detergent and water flow to the mixing tank 21a, and the water flow carries the detergent and is discharged from the first drain port 21b.

Please refer to Figures 13 and 14. 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 backup channel 242a that are interconnected. The outlet of the circulating water channel 241a is used to guide the water flow to distribution. The water inlet of the filter 31 in the filter box 10 and the inlet of the circulating water channel 241a are used to introduce circulating water. Specifically, the circulation pump 61 is used to pump the water in the outer tub 80 to the inlet of the circulation water channel 241a through the circulation pipeline 62.

The circulation pump 61 pumps the water with lint at the bottom of the outer barrel 80 to the entrance of the circulating water channel 241a. The circulating water enters the filter 31 through the circulating water channel 241a. After flowing through the filter 31, the lint remains in the filter. 31, the filtered water flows out from the water outlet of the filter 31 to achieve the purpose of circulating and filtering lint.

The highest position of the circulating water backup channel 242a is higher than the highest position of the circulating water channel 241a. In this way, after the water flows into the circulating water channel 241a from the inlet of the circulating water channel 241a, the resistance of the water flowing through the circulating water channel 241a to the filter 31 is less than the resistance of flowing to the circulating water backup channel 242a. Therefore, under normal use, the circulating water has priority. It flows to the filter 31 through the circulating water channel 241a.

When the filter 31 is clogged, the back pressure at the water outlet of the circulating water channel 241a increases, forcing the circulating water to flow to the circulating water backup channel 242a and be discharged through the circulating water backup channel 242a. It can be seen that the circulating water backup channel 242a plays a safety precaution role and can drain the water in the circulation pipeline 62 in time when the filter 31 is clogged, thereby reducing the risk of pipe explosion and damage to the circulation pump 61 due to a sharp increase in water pressure. probability of failure.

For example, referring to FIG. 10 , the dispenser box 10 has a plurality of receiving

grooves

10 a and 10 b , one of which is used to place the filter 31 , and the remaining receiving

grooves

10 a and 10 b are used to receive the detergent bottle 32 .

For example, please refer to Figures 1 and 10, a plurality of receiving

grooves

10a, 10b are arranged side by side along the left and right directions.

The detergent bottle 32 can contain detergents such as laundry detergent, softener, disinfectant, and perfume. In an embodiment having multiple detergent bottles 32, each detergent bottle 32 is used to store different types of detergent.

Illustratively, the washing equipment includes a door body, a box body, and a door seal 50 provided at the front end of the inner barrel 90 , and the outer tub 80 is provided in the box body. The box body is provided with an opening, and the door body is used to open or close the opening. The door seal 50 is used to seal the gap between the outer tub 80 and the opening of the box. When the door closes the opening, the door sealingly abuts against the door seal 50 .

For example, referring to FIGS. 11 and 13 , the door seal 50 has a water filling port 50 a. Referring to Figures 12 and 13, the washing equipment includes a first water outlet pipeline 71, which communicates with the first drain port 21b and the water injection port 50a. That is to say, the water in the mixing tank 21a is injected into the inner cylinder 90 through the first drain port 21b and the water injection port 50a of the door seal 50. In this way, the detergent is directly poured into the inner cylinder 90 and directly contacts the clothes. Improve detergent utilization.

By way of example, in some embodiments, the inner barrel 90 is provided with lifting ribs. The inner cylinder 90 is provided with water holes in the area covered by the lifting ribs. The inner cylinder 90 has no water holes outside the area covered by the lifting ribs. Water and liquid are exchanged between the inner cylinder 90 and the outer barrel 80 through the water holes. In this embodiment, the clothes will not come into contact with the edge of the water hole, which can reduce the wear of the edge of the water hole on the clothes. In this embodiment, the water liquid directly enters the inner cylinder 90, and the water injected into the inner cylinder 90 will slowly enter the outer bucket 80 through the water hole. In this way, the clothes can be soaked as quickly as possible and the washing efficiency is improved.

For example, the mixing tank 21a is used to receive the filtered water filtered by the filter 31. That is to say, the water filtered by the filter 31 flows directly to the mixing tank 21a below the filter 31. There is no need to set up additional pipelines for drainage. It is enough to reuse the first drainage outlet 21b for drainage. This can simplify the structure, so that The detergent dispensing device 100 has a simpler structure.

It should be noted that the water outlet of the circulating water backup channel 242a can guide the water flow to any suitable position. For example, in some embodiments, water from the water outlet of the circulating water backup channel 242a is directly guided back to the outer tub 80 through a pipeline.

In other embodiments, the water outlet of the circulating water backup channel 242a is connected to the mixing tank 21a, that is, the mixing tank 21a is also used to receive water from the circulating water backup channel 242a. In this way, there is no need to install additional pipelines to connect the circulating water backup. The water outlet of the channel 242a can reuse the first drainage outlet 21b for drainage. This can simplify the structure and make the structure of the detergent delivery device 100 simpler.

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 open, and the box lid 22 is located on the open top side of the box body 21 . The box body 21 and the box lid 22 jointly define a pull-out space 20 a for accommodating the dispenser box 10 .

Please refer to FIG. 6 , the mixing tank 21 a is provided in the box 21 .

For example, the water outlet of the circulating water channel 241a is provided on the box body 21, and the water outlet of the circulating water backup channel 242a is provided on the box cover 22. In this way, there is a height difference between the water outlet of the circulating water backup channel 242a and the water outlet of the circulating water channel 241a. This height difference will generate a corresponding water outlet back pressure, so that the water outlet of the circulating water channel 241a has a higher water outlet priority than the circulating water backup channel. The water outlet priority of channel 242a.

For example, please refer to FIGS. 11 and 13 , the circulating water connector 24 is provided at the rear of the detergent box 20 . The circulating water joint 24 includes a main pipeline 241 and a branch pipeline 242 that are connected to each other. The main pipeline 241 is arranged in the front and rear direction. The rear end of the main pipeline 241 is used to connect to the circulation pipeline 62. The front end of the main pipeline 241 is used to connect to the filter 31. The water inlet plug-in fit.

For example, please refer to 3. The rear wall of the box body 21 is provided with an escape opening 21h, and the front end of the main pipeline 241 extends into the interior of the box body 21 through the escape opening 21h.

The flow channel in the main pipe 241 defines the above-mentioned circulating water passage, and the space in the branch pipe 242 defines the above-mentioned circulating water backup channel 242a.

When the distributor box 10 is pulled out, the front end of the main pipeline 241 is separated from the filter 31. When the distributor is pushed into place, the front end of the main pipeline 241 and the filter 31 are inserted into place.

The top wall of the box cover 22 is provided with a circulating water backup interface 22a, and one end of the branch pipe 242 is connected to the 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 from the rear of the box body 21 to the top side of the box cover 22 and is connected to the circulating water backup interface 22a. In this way, the branch pipe 242 does not need to occupy space in the detergent box 20, which facilitates pipe layout and also makes the detergent box 20 compact.

It should be noted that the main pipeline 241 may be a complete pipeline, or may be formed by connecting multiple segmented pipelines together.

The branch pipeline 242 may be a complete pipeline, or may be formed by connecting multiple segmented pipelines together.

For example, please refer to Figure 6, Figure 7 and Figure 8, the rear wall of the box body 21 is provided with an air pressure balance port 21g. The outer tub 80 has a vent. The washing equipment includes an air pressure balance pipeline, which is connected to the air vent and the air pressure balance port 21g. The space in the outer barrel maintains air pressure balance with the space in the detergent box through the air pressure balance pipe. The space in the detergent box is connected to the external environment. Therefore, the air pressure in the detergent box is the same as the outside atmospheric pressure. , thus achieving the air pressure balance between the outer barrel and the atmospheric environment.

It should be noted that if the outer barrel does not have a vent, the space inside the outer barrel is in a relatively closed state and there will be a certain air pressure. This air pressure will produce a certain back pressure during the water inlet process of the outer barrel and/or the inner barrel, resulting in failure. Water comes in or water comes in slowly.

The specific position of the air pressure balance port 21g can be designed according to actual needs.

For example, please refer to FIG. 14 , the air pressure balance port 21g is located approximately below the circulating water backup interface 22a.

For example, please refer to FIGS. 4 and 5 , a water guide member 221 is provided on the bottom side of the box cover 22 , and the top end of the water guide member 221 is connected to the top wall of the box cover 22 . The water guide 221 is used to guide the water from the circulating water backup interface 22a to the bottom wall of the box 21, and the water flows along the bottom wall of the box 21 to the mixing tank 21a.

The water guide member 221 plays a diversion role in water, reducing the impact force of the water flow on the bottom wall of the box 21 and reducing the noise caused by the impact of the water flow; in addition, it can also reduce the degree of water splashing.

For example, please refer to Figure 3. The bottom end of the water guide member 221 is spaced apart from the bottom wall of the box body 21. In this way, during the assembly process of the box cover 22 and the box body 21, the bottom end of the water guide member 221 will not Interference occurs with the box body 21 .

Illustratively, the box cover 22 is an integrally formed injection molded part, that is, the above-mentioned water guide member 221, the top wall of the box cover 22 and other parts are all integrally injection molded. By way of example, the water guide 221 is located at the rear of the dispenser box 10 . The water guide member 221 will not interfere with the dispenser box 10 and can make full use of the space behind the dispenser box 10 .

It should be noted that the water guide 221 cannot interfere with the plug-in/out fit between the main pipeline 241 and the filter 31, nor can it interfere with the plug-in/out fit between the dosing pump 40 and the detergent bottle 32 described below.

For example, the water guide member 221 is located at the right rear corner of the detergent box. In this way, the water guide member 221 can fully utilize the space in the right rear corner of the detergent box 20 without interfering with the dispenser box 10 .

For example, please refer to Figure 5. The water guide member 221 includes a first water blocking wall 2211. The front surface of the first water blocking wall 2211 is a water guiding surface. The first water blocking wall 2211 is located in front of the air pressure balance port 21g and blocks the air pressure. Balance port 21g. The above-mentioned blocking of the air pressure balance port 21g means that, please refer to FIG. 3 , in a plane projection perpendicular to the pulling direction of the distributor box 10 , the first water blocking wall 2211 blocks the air pressure balance port 21g.

In this embodiment, the first water blocking wall 2211 can block the water flow from splashing to the air pressure balance port 21g, and the splashing water in the detergent box 20 is not easy to splash from the air pressure balance port 21g to the outside of the detergent box 20, so that the air pressure is balanced. The connecting parts of the inlet and air pressure balance pipeline are not prone to water seepage.

The specific structure of the water guide member 221 is not limited. For example, the water guide member 221 is in the shape of a sheet, and the water liquid flows from top to bottom along the guide surface on the front side of the first water retaining wall 2211 . In some embodiments, the first water retaining wall 2211 gradually tilts forward in the top-down direction, so as to facilitate the flow of water along the water guide surface. Of course, the guiding surface does not need to be inclined.

For example, the water guide member 221 is in the shape of a flat tube. Specifically, please refer to Figure 5. The water guide member 221 includes a second water blocking wall 2212. The second water blocking wall 2212 is located on the front side of the first water blocking wall 2211. The left end of the first water blocking wall 2211 is in contact with the second water blocking wall 2212. The left end of the wall 2212 is connected, and the right end of the first water retaining wall 2211 is connected with the right end of the second water retaining wall 2212. The two define a flat guide channel 221a, and water flows in the guide channel 221a. In this way, the water flow can be better restrained and guided, and the impact of the water flow on other components can be reduced.

For example, please refer to FIGS. 3 and 5 , the bottom edge of the second water retaining wall 2212 is lower than the bottom edge of the first water retaining wall 2211 .

In this embodiment, the length of the second water retaining wall 2212 is shorter than the length of the first water retaining wall 2211, which can reduce the cantilever length of the mold of the water guide member 221, improve the stress conditions of the mold, and increase the life and reliability of the mold.

For example, please refer to FIG. 5 , the second water retaining wall 2212 is provided with an opening groove 2212 a, and the opening of the opening groove 2212 a is located at the bottom edge of the second water retaining wall 2212 . The opening groove 2212a extends generally in the up-down direction. The opening groove 2212a can also be changed to the stress condition of the mold. Specifically, the mold is provided with a core at the opening groove 2212a, and the core and the mold portion corresponding to the first water retaining wall 2211 can be connected together. In this way, the mold portion corresponding to the first water retaining wall 2211 can be prevented from becoming thin and long. The cantilever state can improve the stress conditions of the mold and increase the life and reliability of the mold.

For example, please refer to Figures 6 and 9. The bottom wall of the detergent box 20 is provided with a water retaining rib 211 and a second drain port 21d. The water retaining rib 211 separates the lower space of the detergent box 20 from the mixing tank 21a and the second drain port 21d. Drainage channel 21c. The second drainage port 21d is connected with the drainage groove 21c, and is used to drain the water in the drainage groove 21c. That is to say, the first drainage outlet 21b and the mixing groove 21a are located on one side of the water retaining rib 211, and the second drainage outlet 21d and the drainage channel 21c are located on the other side of the water retaining rib 211.

Exemplarily, the washing equipment includes a second water outlet pipe 74 that guides the water discharged from the second drain port 21d between the outer tub 80 and the inner tub 90 .

It can be understood that the water flow cross-sectional area of the second drain port 21d is larger than the water flow cross-sectional area of the first drain port 21b. That is to say, when the amount of water is equally sufficient, the drainage flow rate of the second drainage outlet 21d is greater than the drainage flow rate of the first drainage outlet 21b.

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

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

Since the water from the first drain port 21b needs to be directed to the water filling port 50a of the door seal 50, the maximum water flow rate is limited by the water filling port 50a. The second drain port 21d and the drain groove 21c can promptly guide the water flow in the detergent box 20 to the outer tub 80 in case of overflow, which not only plays a safety protection role, but also speeds up water inflow.

The overflow water level in the mixing tank 21a is determined by the structure of the water retaining rib 211. Specifically, the overflow water level is the lowest water level corresponding to the water retaining rib 211 that allows the water in the mixing tank 21a to flow to the drainage tank 21c.

For example, in some embodiments, the height of the top edge of the water retaining rib 211 is used as the overflow level of the mixing tank 21a. When the water level in the mixing tank 21a continues to rise to the top edge of the water retaining rib 211, the water overflows. The water retaining rib 211 flows from the top side of the water retaining rib 211 to the drainage groove 21c on the second side of the water retaining rib 211, and is discharged from the second drainage outlet 21d.

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

Exemplarily, referring to FIGS. 7 , 8 and 9 , the detergent dispensing device 100 includes a venturi tube 23 disposed below the detergent box 20 . Please refer to Figure 11. The washing equipment includes a water inlet pipeline 72. The inlet 23a (refer to Figure 9) of the Venturi tube 23 is used to connect the water inlet pipeline 72. The first drain outlet 21b is connected to the negative pressure suction port 23c (refer to Figure 9) of the Venturi tube 23. (Refer to Figure 9); the first water outlet pipe 71 is connected to the outlet 23b (refer to Figure 9) of the Venturi tube 23.

When water enters, the water flow from the water inlet pipe 72 flows through the venturi tube 23, and the water flow generates negative pressure at the negative pressure suction port 23c.
