Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and more particularly to an ozone foam generating device and washing equipment. Background Technology

[0002] Detergent foam plays a significant role in cleaning and softening clothes during the washing process. However, current washing equipment typically lacks an active foam generator, requiring a period of washing before foam production. This results in a slow detergent action, and some detergent remains incompletely dissolved in the water, affecting cleaning effectiveness. Furthermore, while gases like ozone have good antibacterial properties, they are difficult to dissolve in water and cannot provide effective sterilization during washing. However, ozone can adhere to the surface of foam and be encapsulated within it, achieving a good sterilization effect upon contact with clothing. However, current foam washing systems fail to fully integrate this sterilization function, focusing solely on washing performance.

[0003] How to integrate the foam washing and sterilization functions into a single design, so as to fully blend the ozone generated by the ozone generator with the detergent foam generated by the foaming device, is a problem that needs to be solved. Summary of the Invention

Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalents, and these embodiments are also included within the scope of the invention.

[0043] This embodiment proposes an ozone foam generator, which is applicable to any application scenario requiring washing and sterilization, such as laundry, handwashing, and appliance washing. The foam sterilization device can be used independently, for example as an automatic foam-dispensing hand sanitizer sensor; it can also be integrated into other washing equipment, such as a washing machine for foam washing and ozone sterilization of clothes, or a dishwasher for foam washing and ozone sterilization of tableware. The ozone foam generator of this embodiment is described below.

[0044] like Figure 1 and Figure 4 As shown, the ozone foam generator of this embodiment includes a housing 17, a detergent dispensing unit, a foaming unit, an ozone generating unit, and a foam degassing unit. The detergent dispensing unit, the foaming unit, and the ozone generating unit are all located inside the housing 17. The foam degassing unit is connected to the foaming unit.

[0045] The detergent dispensing unit includes a storage tank 7 for storing detergent solution, which can be detergent or a diluted solution containing detergent. In practical applications, a replenishment port can be provided in the storage tank 7, and an opening can be provided on the housing 17 at a position corresponding to the replenishment port, with a sealing cap at the opening. When the user needs to replenish the detergent solution in the storage tank 7, the detergent solution can be injected into the storage tank 7 through the replenishment port after opening the sealing cap. In other possible implementations, when the ozone foam generator is configured in the washing equipment, the detergent dispensing box of the washing equipment can be connected to the storage tank 7. After the user dispenses detergent through the detergent dispensing box, the detergent in the dispensing box enters the storage tank 7.

[0046] In a preferred embodiment, such as Figure 1 and Figure 4 As shown, the detergent dispensing unit also includes a dispensing pump 15. The suction end of the dispensing pump 15 is connected to the storage box 7, and the dispensing end is connected to multiple sub-foaming units respectively. It is used to dispense the detergent solution in the storage box 7 to the multiple sub-foaming units. The dispensing pump 15 can also control the amount of detergent solution dispensed. In other possible implementations, the positions of the storage box 7 and the foaming chamber can be designed, and a control valve can be installed on the dispensing pipe connecting the storage box 7 and the foaming chamber. When the control valve opens the dispensing pipe, the detergent solution can be dispensed by gravity alone, without relying on the dispensing pump 15.

[0047] The foaming unit includes multiple sub-foaming units, each of which includes a foaming chamber and an aerator 12 disposed within the foaming chamber. A liquid storage box 7 communicates with the foaming chamber, and the detergent solution within the storage box 7 can be controlled to communicate with one or more of the multiple sub-foaming units according to a preset rule, so that the detergent solution is injected into the corresponding foaming chamber. The number of aerators 12 is not limited, but multiple aerators 12 are preferably provided to improve foaming efficiency. In applications with high foam demand, multiple sub-foaming units can be used to increase foam production and efficiency. In a preferred embodiment, the interior of the foaming chamber has a honeycomb structure to further improve foaming efficiency.

[0048] The ozone generating unit includes an ozone generator 5, the outlet of which is connected to an aeration head 12. The ozone generated by the ozone generator 5 can be controlled to flow into the foaming chamber through the aeration head 12. In a preferred embodiment, the ozone generating unit includes an air pump 6, which is connected to the ozone generator 5 and is used to introduce the ozone generated by the ozone generator 5 into the detergent solution in the foaming chamber through the aeration head 12 for foaming. A one-way valve 4 is also provided between the connecting pipe of the ozone generator 5 and the aeration head 12, and the one-way valve 4 is configured to restrict the ozone to flow only in one direction from the outlet of the ozone generator 5 to the aeration head 12.

[0049] The defoaming unit includes a defoaming tube. The inlet end of the defoaming tube is located inside the housing 17 and communicates with the foaming chamber. The defoaming end of the defoaming tube is located outside the housing 17 so as to discharge the foam overflowing from the foaming chamber.

[0050] The foaming principle of the ozone foam generator in this embodiment is as follows: the detergent solution in the storage chamber enters the foaming chamber, and ozone gas is introduced into the detergent solution in the foaming chamber through the aeration head 12 to foam. After the foam fills the foaming chamber, it will overflow and be discharged out of the shell 17 through the foam discharge pipe for user use.

[0051] This embodiment integrates the detergent dispensing unit, foaming unit, ozone generating unit, and foam defoaming unit, achieving a miniaturized, independent structural design that combines foam washing and ozone sterilization into a single healthy cleaning and sterilization method. It is suitable for various application scenarios requiring washing and sterilization, and can be used independently or integrated into washing equipment. By setting multiple sub-foaming units, different numbers of sub-foaming units can be selected for foaming in different application scenarios and washing processes, thereby improving foaming efficiency.

[0052] In one alternative implementation, the detergent solution in the storage box 7 is controlled to communicate with one or more of a plurality of sub-foaming units according to the washing process, and the foaming cavities of the plurality of sub-foaming units have different cavity volumes.

[0053] For example, in washing machine applications, during the pre-wash stage, a sub-foaming unit with a smaller foaming chamber is activated. While the smaller volume produces less foam, the finer foam penetrates quickly to the surface of the clothes, initially encapsulating large particles of dirt. This fine foam, carried by the water flow, gently rinses the clothes, preventing damage from strong water jets, and loosens the dirt, preparing for the subsequent main wash stage. During the main wash stage, to thoroughly remove stubborn stains such as oil and sweat, a larger foaming chamber is activated. This larger volume produces a large amount of foam, which fully covers every corner of the clothes. The abundant detergent components in the foam fully contact and react with the stains, separating stubborn stains from the fabric fibers through emulsification and decomposition. Simultaneously, the abundant foam acts as a buffer between clothes, reducing friction during washing and protecting the fabric's texture and color.

[0054] In one alternative implementation, such as Figure 1 and Figure 4As shown, the cavity volumes of the multiple sub-foaming units are different. When one or more of the multiple sub-foaming units are connected to the liquid storage box 7, the detergent solution in the liquid storage box 7 can be controlled to be simultaneously added into the foaming cavities of the multiple sub-foaming units, so that the multiple sub-foaming units generate foam simultaneously; or the detergent solution in the liquid storage box 7 can be controlled to be added into the foaming cavities of the multiple sub-foaming units according to a predetermined rule. The predetermined rule includes: controlling the corresponding sub-foaming units to be connected to the liquid storage box in order of increasing foaming cavity volume. That is, detergent solution is first added to the smaller volume foaming cavity, and after foaming begins in the smaller volume foaming cavity, detergent solution is added to the larger volume foaming cavity to further improve the foaming efficiency of each foaming cavity. Alternatively, the detergent solution in the liquid storage box 7 can be controlled to be added into the foaming cavities of some sub-foaming units to select the foaming timing as needed.

[0055] Since it takes time for a larger foaming chamber to fill and overflow with foam from the start of foaming, users cannot use the foam during this time and must wait. Therefore, this embodiment sets up multiple sub-foaming units with different chamber volumes, and all sub-foaming units are sealed. As the aeration head 12 introduces ozone gas into the foaming chamber, the air pressure inside the foaming chamber will increase accordingly. In the same amount of time, the air pressure increase in the smaller foaming chamber is greater than that in the larger foaming chamber. Furthermore, because the foaming chamber has a smaller volume, the foam will fill the smaller foaming chamber first and overflow into the bubble discharge pipe more quickly. This improves the foam overflow efficiency while ensuring the foam output, reduces user waiting time, and enhances the user experience.

[0056] Preferably, there are m sub-foaming units, and there are m corresponding communication paths between the m sub-foaming units and the liquid storage box 7. At least m-1 communication paths are equipped with control valves. The cavity volume of the sub-foaming unit corresponding to the communication path without control valves is the smallest among the m sub-foaming units, so that the foaming unit with the smallest cavity volume participates in foaming during the foaming process, reducing the user's waiting time for foaming.

[0057] Preferred, such as Figure 1 and Figure 4 As shown, the multiple sub-foaming units include a first foaming unit 3 and a second foaming unit 2. The cavity volume of the first foaming unit 3 is larger than the cavity volume of the second foaming unit 2, and the second foaming unit 2 is located inside the first foaming unit 3 to reduce the volume and the space occupied by the foaming unit.

[0058] Preferably, the larger the volume of the foaming chamber, the more aeration heads 12 are installed, thereby shortening the foam overflow time in the larger foaming chamber.

[0059] In one alternative implementation, such as Figure 1 and Figure 4 As shown, the defoaming unit includes multiple defoaming pipes of different diameters. These defoaming pipes are connected to multiple sub-foaming units in a one-to-one correspondence. The larger the diameter of the defoaming pipe, the larger the volume of the corresponding foaming cavity, and the larger the foaming area at the defoaming end. Each sub-foaming unit generates foam independently through its corresponding aeration head 12, and the generated foam overflows through its corresponding defoaming pipe. This embodiment, by setting multiple defoaming pipes of different diameters, allows for the selection of an appropriate defoaming flow rate based on the volume of the foaming cavity. For example, a small-volume foaming cavity is connected to a small-diameter defoaming pipe, allowing the foam overflowing from the small foaming cavity to overflow at a smaller flow rate, thus maximizing the overflow time and preventing foam interruption. A large-volume foaming cavity is connected to a large-diameter defoaming pipe, ensuring sufficient foam output.

[0060] In a preferred embodiment, detergent solution is stopped being added to the smaller foaming chamber when the foam generated by the larger foaming chamber overflows into the defoaming pipe. Since the smaller foaming chamber produces less foam and the larger foaming chamber produces more foam, adding detergent solution to the smaller foaming chamber can be stopped once the foam in the larger foaming chamber overflows into the defoaming pipe. This stops foam generation in the smaller foaming chamber, ensuring sufficient detergent solution is added to the larger foaming chamber, reducing detergent solution consumption, and not significantly reducing foam output.

[0061] In one example, such as Figure 2 and Figure 3 As shown, the defoaming unit also includes a nozzle 18, which is disposed outside the housing 17. The nozzle 18 has multiple receiving passages, and the pipe portions of multiple defoaming tubes located outside the housing 17 are correspondingly received within these receiving passages. The foaming ends of the multiple defoaming tubes together form the liquid outlet end of the nozzle 18. In practical applications, the pipe portions of multiple defoaming tubes located outside the housing 17 can be completely enclosed by an injection-molded part to form a large nozzle. In another example, such as... Figure 5 and Figure 6 As shown, a smaller diameter bubble-draining tube is nested inside a larger diameter bubble-draining tube to further reduce the volume and the space occupied by the bubble-draining unit.

[0062] This embodiment, by sharing a single nozzle with multiple bubble-exhausting tubes or by nesting multiple bubble-exhausting tubes, is more aesthetically pleasing and provides a more direct user experience. It eliminates the confusion for users who don't know which nozzle to use first, while also saving space.

[0063] In one alternative implementation, such as Figure 1 and Figure 4As shown, the ozone foam generator also includes a water inlet pipe 1. The inlet end of the water inlet pipe 1 is located outside the housing 17, and the outlet end of the water inlet pipe 1 is located inside the housing 17 and connected to the liquid storage box 7. The water inlet pipe 1 can be connected to an external water inlet pipe 1 to dilute the detergent solution in the storage chamber, reducing the risk of damage caused by high concentrations of detergent directly contacting clothing or the user's skin.

[0064] In one alternative implementation, such as Figure 1 and Figure 4 As shown, the ozone foam generator includes a foam control unit, which is mounted on the housing 17. The foam control unit is connected to both the detergent dispensing unit and the ozone generating unit. The foam control unit controls the opening and closing of the detergent dispensing unit and the ozone generating unit, thereby controlling the start and stop of foam generation from the ozone foam generator. The foam control unit includes an infrared sensor and / or a control switch 16. In practical applications, the ozone foam generator can be started manually by the user controlling the switch 16, or it can be started by infrared sensing when a hand is detected approaching.

[0065] In this embodiment, the ozone foam generator continuously introduces detergent solution and ozone into the foaming chamber during the foaming process, constantly replenishing the foam. During this process, detergent water and ozone continuously enter the larger foaming chamber, continuously replenishing the foam, ensuring a continuous flow of foam. It is important to note that excessive detergent liquid should not be added, as too much liquid may flow out with the foam, affecting the user experience. Preferably, the volume ratio of ozone gas to detergent solution introduced is no more than 1:2 and no less than 1:1, thereby avoiding detergent solution residue in the foam.

[0066] The ozone foam generator of this embodiment will be described in detail below with reference to a specific example: Figures 1-6 As shown, the ozone foam generator includes a housing 17, a detergent dispensing unit, a foaming unit, an ozone generating unit, and a foam degassing unit. The detergent dispensing unit, the foaming unit, and the ozone generating unit are all located within the housing 17, wherein:

[0067] The detergent dispensing unit includes a liquid storage chamber and a dispensing pump 15, with the liquid storage chamber connected to the suction end of the dispensing pump 15. The foaming unit includes a first foaming unit 3 and a second foaming unit 2. The volume of the first foaming unit 3 is larger than the volume of the second foaming unit 2, and the second foaming unit 2 is located inside the first foaming unit 3. The dispensing pump 15 is connected to the first foaming unit 3 via a first dispensing pipe 9 and to the second foaming unit 2 via a second dispensing pipe 8. The first foaming unit 3 and the second foaming unit 2 are each equipped with an aeration head 12, and the number of aeration heads 12 in the first foaming unit 3 is greater than the number of aeration heads 12 in the second foaming unit 2.

[0068] The ozone generating unit includes an ozone generator 5 and an air pump 6. The air pump 6 is connected to the ozone generator 5. The ozone generator 5 is connected to the aeration heads 12 in the first foaming unit 3 and the second foaming unit 2. A one-way valve 4 is provided on the connecting pipe between the ozone generator 5 and the aeration heads 12 to restrict ozone to flow only to the aeration heads 12.

[0069] The defoaming unit includes a first defoaming tube 10 and a second defoaming tube 11, with the diameter of the first defoaming tube 10 being larger than that of the second defoaming tube 11. The inlet end of the first defoaming tube 10 is connected to the first cavity, and the outlet end is located outside the housing 17. The immersion end of the second defoaming tube 11 is connected to the second cavity, and the outlet end is located outside the housing 17. The first defoaming tube 10 is nested within the first defoaming tube 11, or the first defoaming tube 10 and the second defoaming tube 11 are independently arranged, and the portions of the first defoaming tube 10 and the second defoaming tube 11 located outside the housing 17 are enclosed within the same nozzle 18. The first defoaming tube 10 has a first outlet end 13, and the second defoaming tube 11 has a second outlet end. The outlet area of ​​the first outlet end 13 is larger than the outlet area of ​​the second outlet end 14.

[0070] The housing 17 is equipped with a foam control unit, which is connected to the detergent dispensing unit and the ozone generating unit. The foaming is controlled by the user manually controlling the switch 16 or by the infrared sensor sensing the approach of a hand.

[0071] In the ozone foam generator, during the foaming process, the first foaming unit 3 and the second foaming unit 2 each generate foam independently in their respective foaming chambers, and the foam overflows through their own independent pipelines. The first foaming unit 3 requires time t1 from filling its chamber to overflowing, during which time the user cannot use the foam and must wait. This embodiment adds a second foaming unit 2 with a smaller volume foaming chamber. The second foaming unit 2 only requires time t2 from filling its chamber to overflowing, and t2 is much shorter than t1. Therefore, the user's waiting time is significantly reduced, approaching immediate foam generation. Thus, the volume of the foaming chamber of the second foaming unit 2 does not exceed one-quarter of the volume of the foaming chamber of the first foaming unit 3, ensuring that the second foaming unit 2 can generate foam more quickly.

[0072] Because the second foaming unit 2 uses a smaller volume foaming chamber primarily to shorten the user's waiting time for foaming, less foam overflows from the second foaming tube. To maintain a normal foam volume, it still relies on the foam generated by the first foaming unit 3. Typically, the foaming rate of the second foaming unit 2 is no less than 105 ml / min, and the foaming rate of the first foaming unit 3 is no less than 260 ml / min. During this process, detergent liquid and ozone continuously enter the second foaming unit 2, replenishing the foam continuously. After a duration of t1, the foam in the first foaming unit 3 is also full and begins to overflow. The foam is expelled through the first expulsion tube 10. At this point, the combined action of the first and second expulsion tubes 10 and 11 allows for a continuous flow of high-volume foam for the user. Similarly, during this process, detergent liquid and ozone continuously enter the first foaming unit 3 to continuously generate foam.

[0073] This embodiment also proposes a washing device, which includes a washing drum and the ozone foam generating device mentioned above, with the foam outlet end of the foam discharge pipe connected to the washing drum.

[0074] The washing device in this embodiment is, for example, a washing machine, dishwasher, or shoe washing machine. The description of the washing device in this embodiment is similar to the description of the ozone foam generating device described above, and it has the same beneficial effects as the ozone foam generating device.
