Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a detergent bubble premixing device. Background Technology

[0002] Traditional front-loading washing machines typically pour detergent directly into the drum or mix it with water through a detergent dispenser before it flows into the clothes. This method often results in the detergent not mixing thoroughly and evenly with the water, leading to poor washing performance, and some detergent may be discharged unused, resulting in waste. Although existing technologies have attempted to improve mixing by combining flow channels with water inlet, problems such as low mixing efficiency and uneven detergent distribution still exist. Utility Model Content

[0003] The purpose of this invention is to provide a detergent bubble premixing device that integrates bubble generation technology to achieve precise detergent dispensing and efficient mixing, thereby significantly improving washing effect and resource utilization efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model discloses a detergent bubble premixing device, including a shell, the shell being divided into a liquid inlet chamber, a premixing chamber and a liquid outlet chamber connected in sequence by a partition; the liquid inlet chamber is provided with a detergent inlet and a water inlet; the detergent inlet is connected to a detergent storage device through a liquid dispensing device; the water inlet is connected to a faucet through a water inlet valve; a mixing device is installed in the premixing chamber; the liquid outlet chamber is provided with a mixed liquid outlet, the mixed liquid outlet is provided with a dispensing switch and is connected to the outer tub of a washing machine.

[0006] With the above structure, detergent and water are added to the premixing chamber in measured amounts. The premixing chamber is equipped with a mixing device to mix the two evenly before adding them to the outer tub of the washing machine. This achieves precise detergent dispensing and efficient mixing, thereby significantly improving washing effect and resource utilization efficiency.

[0007] Preferably, the shell is divided into two chambers by a vertical partition. One chamber is a premixing chamber, and the other chamber is divided into an upper and lower inlet chamber and a lower outlet chamber by a horizontal partition. The vertical partition has an inlet connecting the inlet chamber and the premixing chamber, and an outlet connecting the outlet chamber and the premixing chamber. The inlet and outlet are located at opposite ends of the vertical partition, and the mixing device is installed between the inlet and outlet. This dual-chamber design, where the premixing chamber is independently separated, while the inlet and outlet chambers are cleverly integrated into the same chamber by a horizontal partition, allows for orderly flow and conversion of the liquid through the inlet and outlet on the vertical partition. This fully utilizes space, ensures uniform detergent dispensing and mixing, reduces detergent waste, and conserves resources.

[0008] Preferably, the liquid inlet chamber is equipped with a liquid inlet pipe connecting the water inlet and the liquid inlet, and the detergent inlet is connected to the liquid inlet pipe and located between the water inlet and the liquid inlet. This design ensures that any detergent residue in the liquid inlet pipe can be completely rinsed off with clean water.

[0009] Preferably, the detergent inlet is located at the top of the liquid inlet pipe. This design allows the detergent to drip entirely into the liquid inlet pipe by gravity, which is beneficial for the uniform distribution of the detergent; at the same time, it prevents water from entering the detergent inlet and then the liquid dispensing device.

[0010] Preferably, the mixing device is a stirring device, which includes a stirring shaft that is rotatably mounted on the side wall of the premixing chamber, stirring blades disposed on the stirring shaft, and a rotary drive device for driving the stirring shaft to rotate. This design allows for thorough mixing of the mixture through high-speed rotation.

[0011] Preferably, the stirring blades are made of a flexible porous mesh material, with the bottom and sides of the blades contacting the sidewalls of the premixing chamber. This design increases the contact area between the detergent and water, thus helping the detergent dissolve and disperse more quickly in the water. Furthermore, the flexible porous mesh increases the contact area with the sidewalls of the premixing chamber, allowing the detergent liquid deposited at the bottom of the chamber to be swept onto the rotating blades, where its rotation ensures sufficient contact and dissolution with the water. Additionally, it helps generate more water flow and turbulence during the stirring process, further promoting detergent mixing.

[0012] Preferably, the drain chamber is equipped with a drain pipe connecting the drain outlet and the mixed liquid outlet. The drain pipe is curved within the drain chamber and has several right-angle turns. This design increases the direction-changing ability of the water flow, generating more water flow and turbulence, further promoting detergent mixing.

[0013] Preferably, a level gauge is installed inside the premixing chamber, and a perforated plate is installed at the outlet of the mixed liquid. This design allows for monitoring of the liquid level in the premixing chamber during premixing to achieve better mixing results, while also ensuring premixing safety. In addition, the perforated plate design enables uniform water distribution, reduces noise, and filters any insufficiently mixed washing liquid, allowing for further dilution and mixing.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] This invention provides a detergent bubble premixing device that solves the technical problems of low detergent mixing efficiency and uneven distribution of laundry detergent in the prior art. The invention adds a measured amount of detergent and water to the premixing chamber, which is equipped with a mixing device to mix the two evenly before adding them to the outer tub of the washing machine. This achieves precise detergent dispensing and efficient mixing, thereby significantly improving washing effect and resource utilization efficiency. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientation of the detergent bubble premixing device of this utility model when it is working normally, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a detergent bubble premixing device includes a housing 1, which is divided into a liquid inlet chamber 2, a premixing chamber 3, and a liquid outlet chamber 4 connected in sequence by a partition. The liquid inlet chamber 2 is used for the entry of detergent and water, the premixing chamber 3 is used to uniformly mix the entering detergent and water, and the liquid outlet chamber 4 discharges the mixed solution into the outer tub of the washing machine.

[0026] The layout of the liquid inlet chamber 2, the premixing chamber 3, and the liquid outlet chamber 4 is as follows:

[0027] The housing 1 is divided into two chambers by a vertical partition 11. One chamber is a premixing chamber 3, and the other chamber is divided into an upper and lower liquid inlet chamber 2 and a lower liquid outlet chamber 4 by a horizontal partition 12. The vertical partition 11 has an inlet 111 connecting the liquid inlet chamber 2 and the premixing chamber 3, and a drain 112 connecting the drain 4 and the premixing chamber 3. The inlet 111 and drain 112 are located at opposite ends of the vertical partition 11. This invention employs a dual-chamber design, where the premixing chamber is independently separated, while the liquid inlet chamber 2 and the drain 4 are cleverly integrated into the same chamber by the horizontal partition 12. The orderly flow and conversion of liquid are achieved through the inlet and drain on the vertical partition 11, ensuring uniform detergent dispensing and mixing, reducing detergent waste, and conserving resources.

[0028] The liquid inlet chamber 2 is equipped with a detergent inlet 21 and a water inlet 22. The detergent inlet 21 is connected to a detergent storage device 6 via a liquid dispensing device 5. The detergent storage device 6 can be a storage tank or a washing machine drawer; in this embodiment, it is a washing machine drawer. The user adds detergent to the detergent storage device 6 for storage, and then adds a measured amount of detergent to the detergent inlet 21 via the liquid dispensing device 5. In this embodiment, the detergent storage device 6 stores both detergent and fabric softener, so two pipes are provided between the liquid dispensing device 5 and the detergent storage device 6. In practical applications, only one pipe can be designed as needed; this embodiment does not impose any restrictions on this. The water inlet 22 is connected to a faucet via a water inlet valve for introducing clean water.

[0029] An inlet pipe 23 is provided in the inlet chamber 2, connecting the water inlet 22 and the liquid inlet 111. The detergent inlet 21 is connected to the inlet pipe 23 and is located between the water inlet 22 and the liquid inlet 111. This single pipe design ensures that the detergent remaining in the inlet pipe 23 can be completely rinsed off with clean water.

[0030] Preferably, the detergent inlet 21 is located at the top of the liquid inlet pipe 23. This design allows the detergent to drip entirely into the liquid inlet pipe 23 by gravity, which is beneficial for the uniform distribution of the detergent and at the same time prevents water from entering the detergent inlet 21.

[0031] The premixing chamber 3 is provided with an installation port 31, and a mixing device is installed inside the installation port 31, extending into the premixing chamber 3. The mixing device is located between the liquid inlet 111 and the liquid outlet 112. The location of the mixing device between the liquid inlet 111 and the liquid outlet 112 ensures that detergent and water enter the premixing chamber 3 from the liquid inlet 111, and are discharged from the premixing chamber 3 through the liquid outlet 112 after being mixed by the mixing device. This effectively promotes the thorough mixing of detergent and water, improves the effect of the mixed solution, and thus enhances washing efficiency and cleaning effect.

[0032] The mixing device can be a bubble generator or a stirring device.

[0033] If a bubble generator is used, a Venturi bubble generator is preferred. Its working principle is as follows: In the Venturi bubble generator, when water and detergent pass through the contraction section, their flow velocity increases and the static pressure decreases, forming a low-pressure zone. At this time, due to the pressure difference between the detergent and the low-pressure zone, the detergent is drawn into the pipe and mixes with the water flow. Specifically, the detergent typically enters the throat region of the Venturi tube in a high-pressure jet manner. When the high-speed water flow encounters the jetted detergent, it generates intense turbulence and shear force, causing the detergent to rapidly disperse into fine droplets. These fine droplets, under the action of the high-speed water flow, can fully mix with the water to form a uniform detergent solution.

[0034] If a stirring device is used, the stirring device includes a stirring shaft that is rotatably mounted on the mounting port 31, stirring blades disposed on the stirring shaft, and a rotary drive device that drives the stirring shaft to rotate. One end of the stirring shaft extends into the premixing chamber 3 and is rotatably fixed to the inner wall of the premixing chamber 3; the other end extends out of the mounting port 31 and is fixedly connected to the rotary drive device, which is a motor. The stirring blades are made of flexible porous mesh material, and the bottom and sides of the stirring blades contact the side walls of the premixing chamber, respectively. The porous structure can increase the contact area between the detergent and water, thereby helping the detergent to dissolve and disperse in the water more quickly; in addition, the flexible porous mesh can increase the contact area with the side walls of the premixing chamber 3, so that the detergent liquid deposited at the bottom of the premixing chamber 3 is swept onto the stirring blades by the rotating stirring blades, and through its rotation, it can fully contact and dissolve with water; in addition, it can also help generate more water flow and turbulence during the stirring process, further promoting the mixing of detergent.

[0035] A level gauge is installed inside the premixing chamber 3 to monitor the liquid level within the chamber, ensuring the safety and efficiency of the mixing process. The level gauge design further enhances the safety and practicality of the device, providing users with a more convenient and efficient washing experience.

[0036] The drain chamber 4 is equipped with a mixed liquid outlet 41, which has a dispensing switch and is connected to the outer tub of the washing machine to deliver the well-mixed detergent into the washing machine for washing. A drain pipe 42 is installed inside the drain chamber 4, connecting the drain outlet 112 and the mixed liquid outlet 41. To extend the flow path of the mixed liquid, which helps to slow down the liquid flow rate and further promotes uniform mixing, the drain pipe 42 is curved within the drain chamber 4. Preferably, some right-angle bends can be provided on the drain pipe 42 to increase the direction-changing ability of the water flow, generate more water flow and turbulence, and further promote detergent mixing.

[0037] like Figure 5 As shown, a perforated plate 411 is provided on the outlet 41 of the mixed liquid. The design of the perforated plate 411 is twofold: firstly, it refines the incoming water, allowing the water to fall more evenly and avoiding the noise caused by concentrated water flow; secondly, it can filter out viscous detergent, which is further diluted under the continuous impact of the water flow.

[0038] like Figure 6 As shown, this utility model also provides a control method for premixing using the above-mentioned detergent bubble premixing device, including the following steps:

[0039] S1. The washing machine is turned on, the program is running, the washing liquid is added, and after the addition is complete, the liquid dispensing device 5 is turned off. The water inlet valve is opened for 5 seconds and then turned off.

[0040] S2. Water level monitoring: The water level in the premixing chamber 3 is monitored by a level gauge to see if it has reached the predetermined water level. If it has reached the predetermined water level, proceed to the next step; if it has not reached the predetermined water level, the water inlet valve is reopened.

[0041] S3. Start the mixing device. The mixing device will start after a 3-second delay and run for 15 seconds.

[0042] S4. After premixing is completed, the dispensing switch of the mixture outlet 41 is opened, allowing the mixture to flow into the outer tub of the washing machine.

[0043] S5. The washing program is running, the water inlet valve is open, and the washing process begins.

[0044] S6. The premixing program ends, the washing program is completed, and the dispensing switch on the mixed liquid outlet is closed.

[0045] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
