Technical Field
[0001] This utility model belongs to the field of washing machine technology, specifically relating to a rapid dissolving dispensing device and a washing machine. Background Technology
[0002] Current washing machines employ various dispensing methods, using a dispensing device to mix the additive with water, and then the resulting solution enters the washing machine drum. A patent with publication number CN118257106A discloses a dispensing device and a washing machine. The dispensing device includes at least two water supply lines: a water tank supply line and a dispensing water supply line; a water tank containing a dispensing box with a dispensing cavity for storing the additive; the water tank supply line connected to an inlet structure at the top of the water tank, using the inlet water to flush the additive from the dispensing cavity into the water tank, where it dissolves and mixes to form a solution; and the dispensing water supply line connected to the water tank outlet, using the flowing water to extract the mixed solution from the water tank and dispense it outwards. However, the existing dispensing device has a separate negative pressure suction structure from the top cover, resulting in a large overall size and occupying internal space. Furthermore, the dispensing device relies solely on water and the additive to mix and dissolve, leading to poor overall dissolution efficiency.
[0003] A patent disclosed in CN221276111U describes a washing machine, comprising: a cabinet; a drum, disposed inside the cabinet for washing clothes; and a container for dispensing items, disposed inside the cabinet. The container has a storage chamber for holding the items, and a first water inlet communicating with the storage chamber. The first water inlet is connected to an external water source, which enters the storage chamber and mixes with the items to form a washing liquid. A liquid outlet pipe is located at the bottom of the container, and a siphon pipe, connected to one end of the liquid outlet pipe, is located at the bottom of the storage chamber. The siphon pipe draws the washing liquid from the storage chamber to the liquid outlet pipe, and the other end of the liquid outlet pipe communicates with the drum to allow the washing liquid to flow into the drum. A dissolving aid is added, including an agitator disposed inside the storage chamber. The agitator has agitating blades to agitate the washing liquid in the storage chamber to accelerate dissolution. Existing washing machines require a separate mixing chamber with an agitator impeller to improve the solubility of the items, resulting in a complex structure and high manufacturing cost. Therefore, it is necessary to design a rapid dissolving dispensing device and a washing machine to overcome the above difficulties. Summary of the Invention
[0004] This invention addresses the problems existing in the prior art by designing a rapid dissolution dispensing device. This invention generates negative pressure through a first venturi tube, causing the water flow to mix with the dispensing material first; then, the dispensing material is mixed again by the water flow in the counter-current water supply circuit. The dispensing material can be automatically extracted and the dissolution effect is better.
[0005] The objective of this invention is achieved through the following technical solution: a rapid dissolving dispensing device includes a water storage box, a distributor box pluggably connected to the water storage box, and a water circuit plate on the top of the water storage box; the water circuit plate is respectively provided with a counter-current water supply circuit and a dispensing water supply circuit, and a water flow counter-current mixing zone is provided between the counter-current water supply circuit and the dispensing water supply circuit; the water circuit plate is also provided with a liquid inlet channel, and a first venturi tube is provided at the end of the dispensing water supply circuit near the water flow counter-current mixing zone; one end of the liquid inlet channel is connected to the throat of the first venturi tube, and the other end of the liquid inlet channel is connected to the distributor box; the water flow counter-current mixing zone is interconnected with the water storage box, and the water storage box is connected to a washing machine through a pipeline.
[0006] Preferably, the end of the liquid inlet channel away from the first venturi tube is provided with a liquid inlet, and the liquid inlet is connected to the distributor box through a pipeline.
[0007] Preferably, the first venturi tube is a cylindrical body, and the inner diameter of the throat of the first venturi tube is smaller than the inner diameter of the end of the first venturi tube; one end of the first venturi tube is connected to the water supply circuit, and the other end of the first venturi tube is connected to the water flow counter-flushing mixing zone; the two ends of the water flow counter-flushing mixing zone are respectively connected to the counter-flushing water supply circuit and the water supply circuit.
[0008] Preferably, the first venturi tube has a mixed solution outlet at the end near the water flow mixing zone; the counter-flushing water supply path has a counter-flushing water supply outlet at the end near the water flow mixing zone; the mixed solution outlet and the counter-flushing water supply outlet are arranged opposite to each other; the angle between the mixed solution outlet and the counter-flushing water supply outlet is less than or equal to 180 degrees.
[0009] Preferably, a second Venturi tube is provided on the counter-current water supply line, and the second Venturi tube is connected to the water flow counter-current mixing zone; an air pipe is provided between the water circuit board and the water storage box, and the air pipe is connected to the throat of the second Venturi tube.
[0010] Preferably, the counter-flush water supply line is provided with a counter-flush water supply inlet, the dispensing water supply line is provided with a dispensing water supply inlet, and the side of the water storage box is provided with a water inlet valve for water supply.
[0011] Preferably, the water storage box is provided with several water inlet valves on its outer side for water supply, and each water inlet valve is connected to the flushing water inlet and the dispensing water inlet through a pipeline.
[0012] Preferably, the water storage box is provided with a single water inlet valve for water supply on its outer side, and a multi-way connector is provided between the water inlet valve and the water circuit board. The multi-way connector is connected to the flushing water inlet and the dispensing water inlet through a pipeline.
[0013] Preferably, the water circuit board is provided with a first outlet, which is connected to the water flow mixing zone and the water storage box respectively; the water storage box is provided with a second outlet, which is connected to the washing machine through a pipe.
[0014] When the inlet valve is opened, one stream of water enters the counter-flush water supply circuit through the counter-flush water inlet, and another stream enters the dispensing water supply circuit through the dispensing water inlet. When the water flows through the first venturi tube, a negative pressure is generated inside the first venturi tube. Since the liquid inlet channel is connected to the throat of the first venturi tube, the substance in the distributor box is drawn into the first venturi tube through the liquid inlet channel, and then the substance can be initially mixed with the water in the first venturi tube. Since the dispensing water supply circuit is continuously supplying water, the mixed solution is flushed into the counter-flush mixing zone along the water flow. At the same time, the counter-flush water supply circuit is also continuously supplying water, and finally the water in the counter-flush water supply circuit enters the counter-flush mixing zone through the counter-flush water outlet. Thus, the two streams flush each other in the counter-flush mixing zone, thereby performing secondary dissolution of the mixed solution of the substance, resulting in better dissolution effect and higher dissolution efficiency.
[0015] After the water flow undergoes a second flushing and mixing in the water flow mixing zone, the mixed solution flows from the first outlet on the water circuit board into the water storage box, and then enters the washing machine drum from the second outlet on the water storage box.
[0016] A second Venturi tube can also be installed on the counter-current water supply line. By utilizing the Venturi effect, air is drawn in from the air pipe, thereby increasing the air content in the mixed solution when the water flows counter-currently. The diffusion and movement of air bubbles in the mixed solution promotes the dissolution of the added substances, achieving a rapid dissolution effect.
[0017] This utility model also designs a washing machine, wherein the rapid dissolving dispensing device is installed inside the washing machine and is connected to the drum inside the washing machine.
[0018] Compared with the prior art, the present invention has the following advantages: 1. The first Venturi tube and the water flow countercurrent mixing zone are both set inside the water circuit plate, eliminating the need for a separate chamber and reducing the space occupied inside the washing machine; 2. The Venturi effect generated by the first Venturi tube automatically extracts the contents from the dispenser box without the need for an external power source, resulting in a simple, reliable structure with low manufacturing cost; 3. The secondary dissolution of the contents is achieved through the two water supply paths, resulting in more thorough dissolution and higher dissolution efficiency. Attached Figure Description

[0026] Example 1
[0027] like Figures 1 to 4 As shown, this embodiment discloses a rapid dissolving dispensing device, including a water storage box 1, a distributor box 2 pluggably connected to the water storage box 1, and a water channel plate 3 on the water storage box 1; the water channel plate 3 is respectively provided with a counter-flushing water supply channel 4 and a dispensing water supply channel 5, and a water flow counter-flushing mixing zone 6 is provided between the counter-flushing water supply channel 4 and the dispensing water supply channel 5; the water channel plate 3 is also provided with a liquid inlet channel 7, and a first venturi tube 8 is provided at the end of the dispensing water supply channel 5 near the water flow counter-flushing mixing zone 6; one end of the liquid inlet channel 7 is connected to the throat of the first venturi tube 8, and the other end of the liquid inlet channel 7 is connected to the distributor box 2; the water flow counter-flushing mixing zone 6 is interconnected with the water storage box 1, and the water storage box 1 is connected to a washing machine through a pipeline.
[0028] The inlet channel 7 has an inlet 9 at the end furthest from the first venturi tube 8, and the inlet 9 is connected to the distributor box 2 via a pipeline. The first venturi tube 8 is cylindrical, and the inner diameter of the throat of the first venturi tube 8 is smaller than the inner diameter of the end of the first venturi tube 8. One end of the first venturi tube 8 is connected to the water supply path 5, and the other end of the first venturi tube 8 is connected to the water flow counter-flushing mixing zone 6. The two ends of the water flow counter-flushing mixing zone 6 are respectively connected to the counter-flushing water supply path 4 and the water supply path 5. The end of the first venturi tube 8 near the water flow counter-flushing mixing zone 6 has a mixed solution outlet 10; the end of the counter-flushing water supply path 4 near the water flow counter-flushing mixing zone 6 has a counter-flushing water supply outlet 11; the mixed solution outlet 10 and the counter-flushing water supply outlet 11 are arranged opposite each other; the included angle between the mixed solution outlet 10 and the counter-flushing water supply outlet 11 is less than or equal to 180 degrees.
[0029] The flushing water supply circuit 4 is equipped with a flushing water supply inlet 14, and the dispensing water supply circuit 5 is equipped with a dispensing water supply inlet 15. The side of the water storage box 1 is equipped with a water inlet valve 16 for water supply. Several water inlet valves 16 are located on the outside of the water storage box 1, each of which is connected to both the flushing water supply inlet 14 and the dispensing water supply inlet 15 via a pipe. A single water inlet valve 16 is located on the outside of the water storage box 1, and a multi-way connector is provided between the water inlet valve 16 and the water circuit board 3. This multi-way connector is connected to both the flushing water supply inlet 14 and the dispensing water supply inlet 15 via a pipe. The water circuit board 3 has a first outlet 17, which connects to both the water flow flushing mixing zone 6 and the water storage box 1. The water storage box 1 has a second outlet 18, which is connected to the washing machine via a pipe. The rapid dissolving dispensing device is installed inside the washing machine and is connected to the drum inside the washing machine.
[0030] The specific operation process of this embodiment is as follows: When the inlet valve 16 is opened, one stream of water flows along the counter-flush water inlet 14 into the counter-flush water supply circuit 4, and another stream of water flows along the injection water inlet 15 into the injection water supply circuit 5. There are two installation methods for the inlet valve 16: the first is to set multiple inlet valves 16, each connected to the counter-flush water inlet 14 and the injection water inlet 15 via pipelines; the second is to set a single inlet valve 16, connected to the counter-flush water inlet 14 and the injection water inlet 15 via a multi-way connector. This multi-way connector is a standard component and is not shown in the accompanying drawings. When the water flows through the first venturi tube 8, the first... A negative pressure is generated inside the Venturi tube 8. Since the inlet channel 7 is connected to the throat of the first Venturi tube 8, the substance in the dispenser box 2 is drawn into the first Venturi tube 8 along the inlet channel 7, and then the substance can be initially mixed with the water flow in the first Venturi tube 8.

Then the two water flows counter-flushing each other in the water flow counter-flushing mixing zone 6, thereby performing secondary dissolution of the substance mixture solution, resulting in better dissolution effect and higher dissolution efficiency.
[0031] After the water flow is mixed twice in the water flow mixing zone 6, the mixed solution flows from the first outlet 17 on the water circuit board 3 into the water storage box 1, and then enters the drum of the washing machine from the second outlet 17 on the water storage box 1.

An air pipe 13 is provided between the water flow plate 3 and the water storage box 1, and the air pipe 13 is connected to the throat of the second Venturi tube 12. Here, a second Venturi tube 12 can also be installed on the flushing water supply path 4. Utilizing the Venturi effect, air is drawn in from the air pipe 13, thereby increasing the air content in the mixed solution during water flow flushing. The diffusion and movement of air bubbles in the mixed solution promotes the dissolution of the dispensing material, achieving a rapid dissolution effect.
