[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] By installing a blue oxygen device at the electric heating position of the washing machine, hydroxyl free radicals are generated to disinfect clothes. The electric heating is usually installed in the groove at the bottom of the outer drum of the washing machine. The blue oxygen device is separated from the clothes by the inner drum, which is far away from the clothes. During the process of delivering the bactericidal substances, more hydroxyl radicals are degraded and cannot fully act on the clothes, resulting in low utilization rate of bactericidal substances and poor bactericidal effect.

[0047] Based on the above problems, the following embodiments are proposed:

[0048] Example 1:

[0049] like Figure 1 , 2 As shown, this embodiment provides a foam generating device, including:

[0050] The outer casing 1 has a cavity 101, and the outer casing 1 has an air inlet 105, a liquid inlet 102 and a foam outlet 701 communicating with the interior of the cavity 101;

[0051] Hydroxyl electrolysis element 2, wherein the hydroxyl electrolysis element 2 is disposed within the cavity 101;

[0052] Aeration element 3 is disposed in the cavity 101 and is connected to the air inlet 105;

[0053] The hydroxyl electrolysis unit 2 electrolyzes the liquid entering the cavity 101 through the liquid inlet 102 to generate hydroxyl free radicals. By introducing gas into the aeration unit 3, the liquid in the cavity 101 is aerated to generate foam containing hydroxyl free radicals, which is discharged from the foam outlet 701.

[0054] The foam generating device proposed in this embodiment integrates a hydroxyl electrolysis element 2 and an aeration element 3 within the outer shell 1. The hydroxyl electrolysis element 2 is an electrolysis plate, and the aeration element 3 is an aeration head. During operation, the foam generating device generates hydroxyl free radicals by electrolyzing the water in the cavity 101 through the electrolysis plate. At the same time, the aeration head is supplied with air by the air pump 4. The output end of the air pump 4 is connected to the air inlet end of the aeration head through the air pipe 301, which can generate a large number of bubbles in the water. The hydroxyl free radicals are mixed with water and air to form hydroxyl foam. The strong oxidizing properties and activity of the hydroxyl foam enhance the sterilization and cleaning effect on clothing.

[0055] The core principle behind the generation of hydroxyl radicals (·OH) through water electrolysis using electrolytic plates is the formation of highly oxidizing active species on the electrode surface via an electrolytic reaction. The specific process involves the redox reactions of water molecules on the electrode and the transformation of intermediate products. The detailed principle is as follows:

[0056] I. Basic Components of an Electrolysis System

[0057] Electrolytic plates typically consist of an anode (such as a titanium-coated electrode containing noble metal catalysts such as ruthenium and iridium) and a cathode (such as stainless steel or titanium), with a small distance between the two electrodes (usually 1-10 mm), and are immersed in water. When electricity is applied, the direct current electric field drives water molecules to migrate directionally between the two electrodes, undergoing oxidation and reduction reactions respectively.

[0058] II. Anodic Reaction: The Main Pathway for the Generation of Hydroxyl Radicals

[0059] An oxidation reaction occurs at the anode, where water molecules or anions in the water (such as OH-) lose electrons to generate reactive oxygen species such as ·OH.

[0060] The foam generating device proposed in this embodiment, through the setting of hydroxyl electrolysis component 2 and aeration component 3, allows hydroxyl free radicals to mix with water and air to form hydroxyl foam. Spraying the hydroxyl foam directly onto clothing can effectively reduce the degradation of hydroxyl free radicals, allowing more hydroxyl free radicals to participate in the sterilization effect and improve the sterilization effect. At the same time, the continuous bursting of foam generates energy to achieve further sterilization and stain removal effects.

[0061] The foam generating device proposed in this embodiment actively generates foam mixed with bactericidal substances such as hydroxyl radicals, enabling more efficient utilization of these bactericidal substances and achieving a better sterilization effect.

[0062] like Figure 2 As shown, the hydroxyl electrolysis element 2 and the aeration element 3 are both located at the bottom of the housing 1. There is one or more aeration elements 3. Preferably, there is one aeration element 3. The hydroxyl electrolysis element 2 is located on one side of the aeration element 3. The hydroxyl electrolysis element 2 can be placed vertically or horizontally. It is preferred to be placed vertically. The hydroxyl electrolysis element 2 has a wiring terminal 201. The wiring terminal 201 extends out of the housing 1 and is electrically connected to an external power source.

[0063] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,

[0064] The outer shell 1 is provided with an additive dispensing end 104, which has a dispensing port communicating with the cavity 101.

[0065] The additive dispensing end 104 is provided with an openable and closable door 5 at the dispensing port.

[0066] In this embodiment, the inlet 102 is used to connect with an external water supply source to supply water to the outer shell 1 of the foam generator, and the outlet 103 is used to discharge residual water in the outer shell 1. The additive dispensing end 104 is used to dispense fabric treatment agent to further increase the cleaning ability of the foam. A hydroxyl electrolysis element 2 and an aeration element 3 are provided inside the outer shell 1 of the foam generator. The hydroxyl electrolysis element 2 generates hydroxyl free radicals by electrolyzing water, and the aeration element 3 generates bubbles by supplying air through the air pump 4, thereby generating foam containing hydroxyl free radicals in the outer shell 1. An openable and closable door 5 is provided at the dispensing port of the additive dispensing end 104. Preferably, the additive dispensing end 104 is located at the top of the outer shell 1 to facilitate the opening and closing of the door 5. By opening the door 5, detergent and other fabric treatment agents can be dispensed. The fabric treatment agent contains surfactants, which promote foaming and increase foam production while further increasing the cleaning and sterilization effects of the foam.

[0067] In this embodiment, as Figure 3-6 As shown, the cross-section of the additive dispensing end 104 is rectangular, and the shape of the door 5 is adapted to the cross-sectional shape of the dispensing opening, so that the door 5 can close the dispensing opening.

[0068] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown,

[0069] The additive dispensing end 104 protrudes from the top wall of the outer shell;

[0070] The door body 5 has a first nozzle 7 that communicates with the cavity 101. The foam outlet 701 is the opening of the first nozzle 7 located outside the cavity 101. The foam outlet 701 is located on the side facing the outer shell 1.

[0071] In this embodiment, the additive dispensing end 104 protrudes from the top wall of the outer casing 1. This design ensures that when the foam generating device is fully assembled inside the washing machine, the additive dispensing end 104 is in a protruding state. This facilitates the opening and closing of the door 5 and the dispensing of the fabric treatment agent. Furthermore, the first nozzle 7 on the door 5 is also extended. In this state, the foam outlet 701 of the first nozzle 7 faces the dispensing port of the washing machine. Thus, during the operation of the foam generator, water enters the outer casing 1 through the liquid inlet 102, activating the hydroxyl electrolysis unit 2 to electrolyze water and generate hydroxyl free radicals. Simultaneously, the air pump 4 is activated to supply air to the aeration unit 3, generating foam inside the outer casing 1 and encapsulating hydroxyl free radicals to form hydroxyl foam. The pressure accumulated inside the outer casing 1 further aerates the hydroxyl foam through the foam outlet 701 on the first nozzle 7 and sprays it onto the clothes inside the inner drum of the washing machine, thus performing sterilization and other functions on the clothes. As the generated hydroxyl foam is quickly sprayed onto the clothing through the foam outlet 701 on the first nozzle 7, the amount of hydroxyl free radical degradation can be further reduced, allowing more hydroxyl free radicals to participate in the sterilization effect and improve the sterilization effect. At the same time, the continuous bursting of foam generates energy to achieve further sterilization and stain removal effects.

[0072] Optionally, in one implementation of this embodiment, such as Figure 4 , 5 As shown,

[0073] The foam outlet 701 is configured as a strip-shaped opening extending circumferentially along the outer wall of the first nozzle 7.

[0074] In this embodiment, the lower opening of the first nozzle 7 is used for foam entry, the upper end is a closed baffle, and a strip-shaped opening extending circumferentially along the side wall is provided as a foam outlet 701. Preferably, the foam outlet 701 has an angle greater than zero with the horizontal direction, so that the foam outlet 701 has an upward tilting tendency. This strip-shaped opening can be understood as an arc-shaped gap. The design of the foam outlet 701 solves the problem that existing nozzles cannot adapt to the upward spray curtain state. Most existing nozzles are direct spray type, which cannot change the water jet angle and cannot achieve the effect of forming a spray curtain.

[0075] In this embodiment, the first nozzle 7 is combined with the structure design of the foam outlet 701. During the process of the foam being sprayed out through the foam outlet 701, the strip-shaped gap can not only keep the foam in a foaming state, but the arc extension can also achieve a better dispersion effect. The spray curtain foam can be formed without the nozzle rotating, so that the foam is evenly dispersed on the clothing.

[0076] A variety of spraying effects are achieved with a simple structure.

[0077] Optionally, in one implementation of this embodiment, such as Figure 2-6 As shown,

[0078] One end of the door 5 is rotatably connected to one end of the dispensing port of the additive dispensing end 104, and the other end is locked to the other end of the dispensing port of the additive dispensing end 104 by a locking member 8.

[0079] In this embodiment, a connecting post 15 is symmetrically fixedly connected to one end of the door body 5. The connecting post 15 is rotatably connected to the inner wall of the injection port of the additive injection end 104, so that the door body 5 can be opened and closed by rotation at the injection port. The locking member 8 is provided to facilitate the other end of the door body 5 to be locked at the other end of the injection port. Thus, when it is necessary to open the door body 5, the locking member 8 is unlocked, the door body 5 is opened, the fabric treatment agent is injected into the injection port, and then the door body 5 is closed and the locking member 8 is locked to complete the injection operation.

[0080] like Figure 10-14 As shown, preferably, the lock 8 includes a mounting portion 801 and a locking bar portion 802;

[0081] The mounting part 801 is provided with a slot 8011, and the slot 8011 is provided with a through groove 8012 and a limiting groove 8013;

[0082] The locking rod portion 802 includes a cylindrical rod 8021 and a handle 8022;

[0083] The locking element 8 locks the door 5 in the state where it is locked to the dispensing port of the additive dispensing end 104, such as... Figure 14 As shown, one end of the cylindrical rod 8021 is inserted into the locking groove (not shown) corresponding to the delivery port, and the other end is inserted into the slot 8011. The handle 8022 enters the limiting groove 8013 and is limited within the limiting groove 8013.

[0084] like Figure 12 , 13 As shown, when a user needs to open the door 5, they can rotate the handle 8022 out of the limiting groove 8013, and the cylindrical rod 8021 will rotate in the slot 8011. By moving the handle 8022 along the through groove 8012, the cylindrical rod 8021 will leave the lock groove corresponding to the insertion port, thus unlocking the lock 8.

[0085] Optionally, in one implementation of this embodiment, such as Figure 2 As shown,

[0086] The liquid inlet 102 is penetrated by the water inlet component 6, which includes a water inlet connector 601 and a second nozzle 602. The water inlet of the water inlet connector 601 is located outside the outer shell 1, and the second nozzle 602 has a plurality of spaced nozzles facing into the cavity 101.

[0087] In this embodiment, a water inlet 6 penetrates the top wall of the outer shell 1 of the foam generating device. The water inlet of the water inlet connector 601 is located outside the outer shell 1 and is connected to an external water source. Water enters the second nozzle 602 through the water inlet connector 601 and is input into the cavity 101 through multiple second nozzles. The second nozzle 602 is designed so that when water enters, it can disperse and impact the foaming solution inside the outer shell 1, which can effectively help increase the foam production.

[0088] Example 2

[0089] like Figure 7-9 As shown, this embodiment provides a fabric processing device, including:

[0090] The foam generating device in Example 1;

[0091] The main water inlet pipe 9 has a branch water inlet pipe 901. The outlet of the branch water inlet pipe 901 is connected to the inlet 102 of the foam generating device and is used to supply water to the cavity 101.

[0092] Furthermore, the fabric treatment equipment also includes:

[0093] Fabric processing tube 10, wherein a door seal 13 is provided at the opening of the fabric processing tube 10;

[0094] The foam generating device is installed at the bottom of the door seal 13, and the foam outlet 701 end of the foam generating device extends through into the interior of the door seal 13 and faces the interior of the fabric treatment cylinder 10.

[0095] The fabric treatment cylinder 10 has counterweights 11 on both sides of its opening, and the foam generating device is located between the two counterweights 11.

[0096] In this embodiment, by installing a foam generating device between the counterweights 11 on both sides of the door seal 13, it is easier for the foam generating device to spray hydroxyl foam into the inlet of the fabric treatment cylinder 10. Thus, through the setting of the hydroxyl electrolysis component 2 and the aeration component 3, hydroxyl free radicals are mixed with water and air to form hydroxyl foam. Spraying the hydroxyl foam directly onto the clothing can effectively reduce the amount of hydroxyl free radical degradation, allowing more hydroxyl free radicals to participate in the sterilization effect and improve the sterilization effect. At the same time, the continuous bursting of the foam generates energy to achieve a further sterilization and stain removal effect.

[0097] The foam generating device proposed in this embodiment actively generates foam mixed with bactericidal substances such as hydroxyl radicals, enabling more efficient utilization of these bactericidal substances and achieving a better sterilization effect.

[0098] Considering the installation position of the foam generator inside the fabric treatment equipment, it is installed between the two counterweights 11. On the one hand, it is closer to the inner cylinder of the fabric treatment equipment, making it one of the closest positions for the foam generator to quickly spray into the cylinder after water electrolysis. On the other hand, there is generally a certain gap space between the two counterweights 11. This position allows the foam generator to not occupy other space in the fabric treatment equipment, and also eliminates the need to open molds in other spaces of the fabric treatment equipment. Furthermore, with this installation position, detergent or foam beads can be directly added to the foam generator after the door of the fabric treatment equipment is opened, making operation more convenient.

[0099] More specifically, in this embodiment, the foam generating device is installed at the bottom of the door seal 13, positioned between the two counterweights 11. A first nozzle 7, located at the top of the foam generating device, passes through the door seal 13. The water outlet 701 faces the inlet of the fabric treatment cylinder 10, and water is drawn to the inlet 102 via a branch inlet pipe 901 of the main inlet pipe 9. The water then enters the cavity 101 to participate in foaming. The foaming process continues, accumulating water pressure inside the outer casing 1. This pressure propels the hydroxyl foam through the foam outlet 701 on the first nozzle 7 onto the clothing inside the fabric treatment cylinder 10, thus sterilizing the clothing. This allows for rapid application of hydroxyl foam to the clothing, reducing hydroxyl degradation, ensuring the effectiveness of the hydroxyl group, and improving the sterilization effect.

[0100] Furthermore, the bottom of the outer casing 1 of the foam generating device has a liquid outlet 103 that communicates with the interior of the cavity 101, and the liquid outlet 103 is connected to the drain pipe 12.

[0101] like Figure 7-9 As shown, a fabric treatment device includes:

[0102] The foam generating device in Example 1;

[0103] Main water inlet pipe 9, the main water inlet pipe 9 having a branch water inlet pipe 901, the output end of the branch water inlet pipe 901 being connected to the liquid inlet 102, for supplying water to the cavity 101;

[0104] Fabric processing cylinder 10, with a door seal 13 at the inlet of the fabric processing cylinder 10, and counterweights 11 on both sides of the fabric processing cylinder 10.

[0105] The foam generating device is installed at the bottom of the door seal 13 and located between the two counterweights 11. The additive dispensing end 104 protrudes from the door seal 13, and the foam outlet 701 faces the dispensing port of the fabric treatment cylinder 10.

[0106] Drain pipe 12, the liquid outlet 103 is connected to the drain pipe 12.

[0107] In this embodiment, a fabric processing cylinder 10 is installed inside the housing of the fabric processing equipment. A door seal 13 is installed at the clothing inlet at the front end of the fabric processing cylinder, and counterweights 11 are symmetrically arranged on the outside of the door seal 13. A hydroxyl foam generator is installed between the two counterweights 11. The outer shell 1 of the foam generator is located below the door seal 13. The first nozzle 7 located at the top of the foam generator passes through the door seal 13. The water outlet 701 faces the inlet of the fabric processing cylinder 10 and is guided to the liquid inlet 102 through a branch water inlet pipe 901 of the main water inlet pipe 9. The water flows into the cavity 101 to participate in foaming. The foaming process continues, and water accumulates and pressurizes inside the outer shell 1. The pressure can spray the hydroxyl foam through the foam outlet 701 on the first nozzle 7 onto the clothing inside the fabric processing cylinder 10 to disinfect the clothing. This allows the hydroxyl foam to be sprayed onto the clothing quickly, reducing the degradation of hydroxyl groups, ensuring the effectiveness of the hydroxyl groups, and improving the disinfection effect.

[0108] By setting up the hydroxyl electrolysis component 2 and the aeration component 3, hydroxyl free radicals are mixed with water and air to form hydroxyl foam. Spraying the hydroxyl foam directly onto clothing can effectively reduce the degradation of hydroxyl free radicals, allowing more hydroxyl free radicals to participate in the sterilization process and improve the sterilization effect. At the same time, the continuous bursting of the foam generates energy to achieve further sterilization and stain removal effects.

[0109] The foam generating device proposed in this embodiment actively generates foam mixed with bactericidal substances such as hydroxyl radicals, enabling more efficient utilization of these bactericidal substances and achieving a better sterilization effect.

[0110] Furthermore, the inlet 102 of the foam generator is connected to the inlet valve (not shown) of an external water source through a branch inlet pipe 901 of the main inlet pipe 9, supplying water to the cavity 101.

[0111] Further, preferably, the drain pipe 12 is an emergency drain pipe in the fabric treatment equipment. The emergency drain pipe is used to discharge residual water and the like inside the outer casing 1 of the foam generating device to the drain pump 16 corresponding to the emergency drain pipe, and then discharge it to the outside of the fabric treatment equipment through the drain pump 16.

[0112] In fabric processing equipment, the emergency drain pipe is usually used when the drain pump 16 / valve fails to work. It is normally closed, while the regular drain pipe is connected to the drain port of the drain pump 16 and directly connects to the external space. It is normally open. Connecting the outlet 103 on the outer casing 1 to the emergency drain pipe instead of connecting to the regular drain pipe simplifies the drainage process. It does not require the drain pump 16 to work before entering the regular drain pipe, and it does not affect the working rhythm of the drain pump 16 corresponding to the regular drain pipe.

[0113] In summary, the ingenious design of the foam generating device and fabric treatment equipment lies in:

[0114] First, by using hydroxyl electrolysis and aeration components, hydroxyl free radicals are mixed with water and air to form hydroxyl foam. Spraying this hydroxyl foam directly onto clothing can effectively reduce the degradation of hydroxyl free radicals, allowing more hydroxyl free radicals to participate in the sterilization process and improving the sterilization effect. At the same time, the continuous bursting of the foam generates energy to achieve further sterilization and stain removal effects. The foam generating device actively generates foam mixed with bactericidal substances such as hydroxyl free radicals, allowing these bactericidal substances to be utilized more efficiently and achieving a better sterilization effect.

[0115] Secondly, an openable and closable door is provided at the additive dispensing port on the top of the outer shell, which facilitates the opening and closing of the door. By opening the door, detergents and other fabric treatment agents can be dispensed. The fabric treatment agents contain surfactants, which promote foaming and increase foam production, while further enhancing the cleaning and sterilization effects of the foam.

[0116] Third, the additive dispensing end is designed to protrude from the top wall of the outer casing. This design ensures that when the foam generating device is fully assembled inside the washing machine, the additive dispensing end is in a protruding state. This not only facilitates the opening and closing of the door and the dispensing of the fabric treatment agent, but also allows the first nozzle located on the door to extend. In this state, the foam outlet of the first nozzle faces the dispensing port of the washing machine. The structural design of the first nozzle combined with the foam outlet allows the foam to maintain its foaming state through the strip-shaped gaps during the spraying process. Furthermore, the arc-shaped extension achieves a better dispersion effect. A spray curtain of foam can be formed without rotating the nozzle, allowing the foam to be evenly dispersed on the clothes. Multiple spraying effects are achieved on a simple structure.

[0117] Fourth, a water inlet is inserted through the top wall of the outer shell of the foam generating device. The water inlet of the water inlet connector is located outside the outer shell and is connected to the external water source. Water enters the second nozzle through the water inlet connector and is input into the cavity through multiple second nozzles. The setting of the second nozzle enables the foaming solution inside the outer shell to be dispersed and impacted when water is introduced, which can effectively help increase the foam production.

[0118] Fifth, the foam generator is installed inside the fabric treatment equipment between the two counterweights. This position is advantageous because it is closer to the inner cylinder of the fabric treatment equipment, making it one of the closest locations for the foam generator to quickly spray water into the cylinder after electrolysis. Additionally, there is usually a gap between the two counterweights, which prevents the foam generator from occupying additional space in the fabric treatment equipment and eliminates the need for additional molds in other areas. Furthermore, this position allows for direct access to the foam generator by opening the door of the fabric treatment equipment and adding detergent or foam beads directly, making operation more convenient.

[0119] It can be further understood that in this disclosure, "multiple" refers to two or more, and other quantifiers are similar. "And / or" describes the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0120] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0121] It is further understood that although operations are described in a specific order in the accompanying drawings in the embodiments of this disclosure, this should not be construed as requiring these operations to be performed in the specific order or serial order shown, or requiring all of the shown operations to be performed to obtain the desired result. In certain environments, multitasking and parallel processing may be advantageous.
