Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a clothing processing device and a washing control method for the clothing processing device. Background Technology

[0002] Detergent foam plays a significant role in cleaning and softening clothes during the washing process. However, current garment processing equipment typically lacks an active foam generator, requiring a period of washing before foam is produced. This results in a slower detergent release of its effects, and some detergent may not dissolve completely in the water, impacting the cleaning performance.

[0003] Some washing machines are equipped with foam generating devices, mainly using two technical solutions: one is to generate foam when detergent is added and water is added, spraying it from the top onto the surface of the clothes. Once the detergent is added, the foaming function stops, resulting in poor cleaning. The other is to place the foam generator at the bottom of the outer drum or at the drain pipe. In this case, the foam cannot directly cover the surface of the clothes, resulting in an unsatisfactory cleaning effect. Furthermore, users cannot directly observe the foam spraying process, making it difficult to intuitively perceive the effect of foam washing. Summary of the Invention

[0004] To overcome the problem that existing foam generating devices in garment processing equipment cannot continuously apply foam to the surface of clothes during washing, resulting in poor cleaning effect, this invention proposes a garment processing device and a washing control method for the garment processing device. This method involves draining washing water from the garment processing drum into the foam generating device for foaming treatment, and then draining the foam back into the garment processing drum from the top. On one hand, the foam generating device draws water from the garment processing drum, allowing for continuous foaming during the washing process. On the other hand, by placing the drain end of the foam generating device's foam delivery pipe at the top of the garment processing drum, the detergent foam entering the drum can cover the surface of the clothes from top to bottom. This improves the cleaning effect, and users can also directly observe the foam spraying process through the garment inlet of the garment processing drum, thus intuitively experiencing the foam washing effect.

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0068] Current foam generating devices in garment processing equipment cannot continuously apply foam to the surface of clothes during washing, resulting in poor cleaning performance. This invention proposes a garment processing device and its washing control method. The device drains washing water from the bottom of the garment processing drum into a foam generating device for foaming. After foaming, the foam is then discharged back into the drum from the top. This design allows the foam generating device to draw water from the drum, continuously generating foam during the washing process. Furthermore, by placing the foam generating device's outlet at the top of the drum, the detergent foam entering the drum can cover the surface of the clothes from top to bottom. This improves cleaning performance, and users can visually observe the foam spraying process through the garment inlet, thus directly experiencing the foam washing effect.

[0069] The following is combined with Figure 1 - Appendix Figure 4 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0070] Example

[0071] like Figure 1 and Figure 2 As shown, a first aspect of the present invention provides a garment processing device, comprising:

[0072] Clothing disposal drum 90;

[0073] Foam generating device 1 includes a foam generating chamber and a foamer for foaming the liquid in the foam generating chamber. The foam generating chamber has a liquid inlet 101 and a foam outlet 301.

[0074] The liquid inlet 101 is connected to the clothing treatment cylinder via a liquid inlet pipe, and the foam outlet 301 is connected to the clothing treatment cylinder 90 via a foam delivery pipe 302. The foam delivery pipe 302 is connected to the clothing treatment cylinder 90 at the top of the clothing treatment cylinder 90.

[0075] In this embodiment of the invention, the washing water in the clothes treatment drum 90 is discharged into the foam generating device 1 for foaming treatment, and after foaming, the foam is discharged back into the clothes treatment drum 90 from the top position. On the one hand, the foam generating device draws water into the clothes treatment drum 90, so that the washing water in the clothes treatment drum 90 can be continuously used for foaming during the washing process. On the other hand, by setting the drain end of the foam delivery pipe 302 of the foam generating device 1 at the top of the clothes treatment drum 90, the detergent foam entering the clothes treatment drum can cover the surface of the clothes in the clothes treatment drum from top to bottom. This not only improves the washing effect of the clothes, but also allows the user to directly observe the foam spraying process through the clothes inlet of the clothes treatment drum, so as to directly feel the foam washing effect.

[0076] Preferably, the aforementioned clothing processing equipment is a washing machine or a washer-dryer combo.

[0077] In some implementations, such as Figure 1 and Figure 2 As shown, the foam generating device 1 is located below the clothing treatment cylinder 90. The clothing treatment cylinder 90 is connected to the foam generating device 1 through the liquid inlet 101 and the foam outlet 301 of the foam generating device to form a circulation path.

[0078] The foam generator includes an aeration module 40 located inside the foam generating chamber and an air pump 60 located outside the foam generating chamber. The exhaust end of the air pump 60 is connected to the aeration module 40. Preferably, the aeration module 40 is a porous, mesh foam generator or a negative pressure jet device.

[0079] The laundry treatment drum 90 and the foam generating device 1, which form a circulation path, allow the washing water in the laundry treatment drum 90 to enter the foam generating chamber under the action of gravity when the air pump 60 is off. When the air pump 60 is on, the washing water in the laundry treatment drum 90 stops entering the foam generating chamber, and the on-board air pump 60 can drive the aeration module 40 to foam the washing water in the foam generating chamber.

[0080] Since the foam generating device 1 and the clothes handling drum 90 form a loop, when the air pump 60 is turned off, there is no air intake pressure in the foam generating device 1. At this time, the washing water in the clothes handling drum 90 can enter the foam generating chamber of the foam generating device by its own gravity. However, when the air pump 60 is turned on, because there is air intake pressure in the foam generating device 1, the washing water in the clothes handling drum 90 cannot enter the foam generating chamber of the foam generating device 1 by its own gravity under the action of pressure difference. At this time, under the action of air intake pressure, the foam generated by the foam generating device 1 can be forced into the clothes handling drum 90 through the foam delivery pipe 302. At the same time, if there is washing water in the foam generating chamber, under the action of pressure difference, the washing water in the foam generating chamber can also be forced into the clothes handling drum 90 through the foam delivery pipe 302.

[0081] In this embodiment of the invention, by reasonably controlling the opening of the air pump 60, on the one hand, the automatic water intake and automatic water intake stop effects of the foam generating device 1 can be achieved, and on the other hand, the water intake of the foam generating device 1 can be reasonably controlled. Thus, while ensuring the automatic water intake and stop effects, the foaming effect of the foam generating device 1 is improved, thereby improving the washing effect of the clothing treatment equipment on the clothes.

[0082] In some implementations, such as Figure 1 and Figure 2 As shown, the garment processing equipment also includes a gas generator 70 capable of generating sterilizing gas, which is connected to the air inlet of the air pump 60.

[0083] In this embodiment of the invention, by setting a gas generator 70 with a sterilization function, a gas with a sterilizing function can be incorporated into the foam when the foam generating device is foaming, so that when the foam is input to a designated location to treat the object, it can also be sterilized.

[0084] Preferably, the gas generator 70 is an ozone generator. Taking the foam generating device installed in the clothing processing equipment as an example, the foam generated by the foam generating device can be applied to the clothes in the clothing processing equipment, thereby improving the washing effect of the clothes. At the same time, the foam containing ozone can also sterilize the clothes when it comes into contact with them, thereby further improving the washing effect of the clothes.

[0085] It should be noted that, regarding health and sterilization, the sterilizing gases produced by gas generators such as ozone generators, which have good sterilization effects, are difficult to dissolve in water and cannot achieve a good sterilization effect during washing. However, they can adhere to the surface of foam and be encapsulated inside the foam, achieving a good sterilization effect when the foam comes into contact with clothing. In this embodiment, by connecting the ozone generator and the foamer together, the sterilizing gas can adhere to the surface of the detergent foam and enter the clothing treatment drum along with the detergent foam to act on the surface of the clothing, thereby sterilizing the clothing.

[0086] In some embodiments, an inlet check valve 104 is provided on the inlet pipe. The inlet check valve 104 is designed to allow liquid to flow into the foam generating chamber through the inlet pipe and to restrict the liquid in the foam generating chamber from flowing out through the inlet pipe.

[0087] An exhaust pipe 103 is also provided between the air pump 60 and the aeration module 40. An exhaust one-way valve 105 is provided on the exhaust pipe 103. The exhaust one-way valve 105 is designed to allow gas to enter the foam generating chamber through the exhaust pipe 103 and to restrict the liquid in the foam generating chamber from being discharged through the exhaust pipe 103.

[0088] In this embodiment of the invention, by setting an inlet check valve 104 on the inlet pipe, it can be ensured that the washing liquid in the foam generating chamber will not be discharged through the inlet pipe under the action of air pressure during the foam generating device's aeration foaming process. By setting an exhaust check valve 105 on the exhaust pipe 103, it can be ensured that the washing liquid in the foam generating chamber will not enter the air pump 60 and gas generator 70 through the exhaust pipe 103 during the liquid feeding process of the foam generating chamber, so as to avoid damage to the devices.

[0089] In some implementations, such as Figure 1 and Figure 2 As shown, the foam generating chamber includes an inlet chamber 10, an outlet chamber 20, and a foam chamber 30. The inlet chamber 10 and the outlet chamber 20 are arranged adjacent to each other, and are separated at the bottom but connected at the top. The outlet chamber 20 and the foam chamber 30 are arranged adjacent to each other, and are separated at the bottom but connected at the top.

[0090] The bottom of the liquid inlet chamber 10 is provided with a liquid inlet 101, the bottom of the foam chamber 30 is provided with a foam outlet 301, and the aeration module 40 is located at the bottom of the liquid inlet chamber 10.

[0091] In this embodiment of the invention, the foam generating chamber is configured as an inlet chamber 10, an outlet chamber 20, and a foaming chamber 30. The inlet chamber 10 and the outlet chamber 20 are arranged adjacent to each other, and the outlet chamber 20 and the foaming chamber 30 are arranged adjacent to each other. At the same time, the inlet of the inlet chamber 10 is located at the bottom, and the outlet 301 of the foaming chamber 30 is located at the bottom. In this way, the washing liquid can enter the inlet chamber 10 from the bottom and be foamed by the aeration module 40. The foamed foam can enter the outlet chamber 20 and the foaming chamber 30 sequentially from the top of the inlet chamber 10, and finally be discharged to the designated working position through the outlet 301 of the foaming chamber 30. When the washing liquid in the inlet chamber 10 is consumed, the washing liquid can enter the inlet chamber 10 again through the inlet 101 at the bottom of the inlet chamber 10. Since the liquid enters from the bottom of the inlet chamber 10, the washing liquid that enters the inlet chamber 10 again can discharge the low concentration washing liquid that was left at the bottom of the inlet chamber 10 after the previous foaming into the outlet chamber 20 adjacent to the inlet chamber 10 for storage. This avoids the low concentration washing liquid from directly entering the foaming chamber 30 and blocking the outlet 301 of the foaming chamber 30. Thus, the foaming effect of the inlet chamber 10 is guaranteed while the foam delivery effect of the foaming chamber 30 is guaranteed.

[0092] It should be noted that by setting the foam outlet 301 of the foam cavity 30 at the bottom, this embodiment of the invention can also ensure that all the foam entering the foam cavity 30 is discharged, thereby avoiding the presence of foam residue in the foam cavity 30 due to the foam outlet 301 being set too high.

[0093] It should also be noted that the liquid inlet chamber 10, liquid outlet chamber 20, and foam chamber 30 in the embodiments of the present invention can be arranged sequentially adjacent to each other along a certain direction, or they can not be arranged sequentially adjacent to each other along a certain direction, as long as the liquid inlet chamber 10 and the liquid outlet chamber 20 are arranged adjacent to each other, and the liquid outlet chamber 20 and the foam chamber 30 are arranged adjacent to each other. However, it is relatively preferred that the liquid inlet chamber 10, the liquid outlet chamber 20, and the foam chamber 30 are arranged sequentially adjacent to each other along a certain direction.

[0094] Preferably, the bottom surface of the liquid inlet chamber and the bottom surface of the foam chamber are both higher than the bottom surface of the liquid outlet chamber; the top connection point of the liquid inlet chamber 10 and the liquid outlet chamber 20 is higher than the top connection point of the liquid outlet chamber 20 and the foam chamber 30; a siphon structure is provided between the liquid outlet chamber 20 and the foam chamber 30.

[0095] In some implementations, such as Figure 1 and Figure 2As shown, the foam generating device 1 includes an outer shell, inside which are formed an inlet chamber 10, an outlet chamber 20, and a foam chamber 30. The inlet chamber 10, the outlet chamber 20, and the foam chamber 30 are all open mouths with closed bottoms and open tops. A top channel is defined between the top of the outer shell and the top of the inlet chamber 10, the top of the outlet chamber 20, and the top of the foam chamber 30.

[0096] The top channel connects the inlet chamber 10 and the outlet chamber 20 at the top, and also connects the outlet chamber 20 and the foam chamber 30 at the top.

[0097] In this embodiment of the invention, by setting the liquid inlet chamber 10, the liquid outlet chamber 20, and the foam chamber 30 as open mouths with closed bottoms and open tops, the effective volume of the liquid inlet chamber 10, the effective volume of the liquid outlet chamber 20, and the effective volume of the foam generating device can be maximized during use.

[0098] Meanwhile, the top channel defined between the outer shell of the foam generating device 1 and the inlet chamber 10, the outlet chamber 20, and the foam chamber 30 allows the foam and / or liquid overflowing from the inlet chamber 10 to be discharged only sequentially through the outlet chamber 20 and the foaming chamber 30, thereby preventing the foam overflowing from the inlet chamber 10 from flowing to places other than the outlet chamber 20 and the foaming chamber 30, thus effectively improving the performance of the foam generating device 1 during use.

[0099] In some implementations, such as Figure 1 and Figure 2 As shown, the foam generating device 1 also includes:

[0100] The siphon device 50 is located between the drain chamber 20 and the foam chamber 30. It is used to drain the liquid in the drain chamber 20 into the foam chamber 30 when the liquid level in the drain chamber 20 reaches the preset liquid level.

[0101] In this embodiment of the invention, a siphon device is provided between the drain chamber 20 and the foaming chamber 30. When the liquid level in the drain chamber 20 exceeds the highest point of the siphon channel, the liquid in the drain chamber 20 is completely discharged into the foaming chamber 30 under the action of the siphon principle. The liquid in the foaming chamber 30 can be drained away by pressurizing the foam generating device 1.

[0102] In some implementations, such as Figure 1 and Figure 2As shown, the volume of the inlet chamber 10, the volume of the outlet chamber 20, and the position of the siphon device are designed such that after all the liquid in the inlet chamber 10 is discharged into the outlet chamber 20, the liquid level in the outlet chamber 20 is higher than the siphon point height of the outlet chamber siphon device 50, and the siphon device 50 is located near the bottom of the outlet chamber 20 at the suction end, and the volume of the outlet chamber 20 is less than or equal to the volume of the foam chamber 30 below the suction end of the siphon device 50, so that when the outlet chamber 20 needs to be emptied, all the liquid in the outlet chamber 20 can be discharged into the foam chamber 30 through the siphon device 50.

[0103] In some implementations, such as Figure 1 and Figure 2 As shown, the foam generating device also includes:

[0104] A spray inlet pipe 100 is provided, a spray inlet valve 1001 is provided on the spray inlet pipe 100, and a spray head 1002 is provided at the outlet end of the spray inlet pipe 100.

[0105] The spray head corresponds to the top opening of the liquid inlet chamber 10.

[0106] In this way, during the foaming process of the foam generating device, the spray water inlet valve 1001 can be opened, so that the spray head 1002 can shoot out a high-speed water flow, which impacts the washing liquid in the liquid inlet chamber 10, thereby promoting foaming and increasing the amount of foam.

[0107] In some implementations, such as Figure 1 and Figure 2 As shown, the garment processing equipment includes:

[0108] The detergent dispenser 80 has a main wash water inlet valve 801 connected to one end and a clothes handling drum 90 connected to the other end via a main wash water inlet pipe 802. It is used to drain the washing water mixed with detergent in the detergent dispenser 80 into the clothes handling drum 90.

[0109] In other words, in the clothing processing device of this embodiment, the main water inlet pipe is still connected to the detergent box when the washing water is introduced, so that the detergent in the detergent box 80 can be brought into the clothing processing drum 90 at the same time when the water is introduced.

[0110] In some implementations, such as Figure 1 and Figure 2 As shown, the liquid inlet pipe includes a first pipe 300, a second pipe 500 and a third pipe 600. One end of the first pipe 300 is connected to the clothes handling drum and the other end is connected to the water inlet of the water pump 400. The drain end of the water pump 400 is connected to the second pipe 500 and the third pipe 600.

[0111] Preferably, at least part of the drainage pipe 300 connected to the water pump is a corrugated pipe section to absorb the vibration and noise generated by drainage.

[0112] One of the second pipe 500 and the third pipe 600 is connected to the liquid inlet 101 of the foam generator, and the drain pipe connected to the liquid inlet 101 is provided with an emergency drain outlet 700.

[0113] In this embodiment of the invention, by setting the liquid inlet pipe connected to the foam generating device 1 at the emergency drain outlet 700 of the clothing processing equipment, the installation and disassembly of the drain pipe can be facilitated.

[0114] In some implementations, such as Figure 1 and Figure 2 As shown, the garment processing equipment also includes:

[0115] A heating tank 200 is located at the bottom of the clothing processing drum 90;

[0116] The inlet end of the inlet pipe is connected to the heating tank 200.

[0117] In this embodiment of the invention, by connecting the inlet end of the inlet pipe to the heating tank 200, the heated washing water can be guided into the foam generating chamber of the foam generating device 1, thereby further improving the foaming effect of the foam generating device 1.

[0118] Furthermore, a second aspect of the present invention provides a washing control method for a garment processing device. This washing control method is applied to the garment processing device provided in the first aspect, wherein the garment processing device has a washing program, and the washing control method includes:

[0119] During the washing program, the air pump 60 is controlled to periodically turn on and off according to the preset first cycle;

[0120] When the air pump 60 is controlled to be turned off, water enters the foam generating chamber; when the air pump 60 is controlled to be turned on, water enters the foam generating chamber and stops.

[0121] Preferably, the above-mentioned washing program is an ozone foam washing program.

[0122] In this embodiment of the invention, by controlling the intermittent operation of the air pump 60 during the washing program, the automatic water intake and automatic water stop effects of the foam generating device can be achieved. On the other hand, the water intake of the foam generating device 1 can be reasonably controlled, thereby improving the foaming effect of the foam generating device 1 while ensuring the automatic water intake and stop effects, and thus improving the washing effect of the clothing treatment equipment on the clothes.

[0123] In some embodiments, the washing control method further includes:

[0124] When the air pump 60 is turned on, the gas generator 70 is controlled to turn on; when the air pump 60 is turned off, the gas generator 70 is controlled to turn off.

[0125] In this embodiment of the invention, when the foamer is foaming the detergent, it simultaneously introduces the antibacterial gas generated by the gas generator, so that the detergent foam and the antibacterial gas are fully combined and discharged into the clothes treatment drum 90 to act on the surface of the clothes, thereby improving the cleaning effect of the clothes and the antibacterial effect of the clothes.

[0126] Furthermore, in some embodiments, the air pump 60 is controlled to periodically turn on and off according to a preset first cycle, including:

[0127] The duration for which the air pump 60 is turned off is the first duration, and the duration for which the air pump 60 is turned on is the second duration;

[0128] in

[0129] During the first period after the air pump 600 is shut down, the amount of water entering the liquid inlet chamber 10 does not exceed the volume of the liquid inlet chamber 100.

[0130] During the second period after the air pump 600 is turned on, the amount of water consumed by the aeration module 40 during the second period is not less than the amount of water entering the liquid inlet chamber 10 during the first period.

[0131] Preferably, during the first period after the air pump 600 is shut off, the water intake of the liquid inlet chamber 10 is equal to the volume of the liquid inlet chamber 100; in this way, the high-concentration detergent entering the liquid inlet chamber 10 during the first period can completely drain the low-concentration detergent remaining at the bottom of the liquid inlet chamber 10 after the previous foaming into the drain chamber 20, thereby improving the foaming effect of the detergent in the liquid inlet chamber 10.

[0132] Preferably, during the second period of operation of the air pump 600, the amount of water consumed by the foamer 40 during the second period is equal to the amount of water entering the liquid inlet chamber 10 during the first period. This allows the foamer 40 to fully foam the washing liquid in the liquid inlet chamber 10 during the second period, thereby maximizing the foaming of the washing liquid in the clothes treatment drum 90 during the washing cycle and thus maximizing the washing effect on the clothes.

[0133] To better understand the control logic of the clothing processing device under the washing program in the embodiments of the present invention, the following uses a washing machine as an example of the clothing processing device. Figures 1-4 Please provide a detailed explanation:

[0134] S1 - The washing machine runs an ozone foam wash program: The user selects to run a foam wash program. Preferably, the foam generated in this foam wash program contains ozone, hydroxyl radicals and other substances with antibacterial properties.

[0135] S2 - Detergent Dosing and Main Wash Water Inlet: The user manually adds detergent, or the washing machine automatically adds an appropriate amount of detergent and simultaneously opens the main wash water inlet valve 801 to add an appropriate amount of main wash water. Preferably, the amount of main wash water added is 10%-30% of the total main wash water volume, in order to obtain a higher detergent concentration for foaming;

[0136] S3 - Foam Generator Inlet for Washing Liquid: The inlet pipe of the foam generator is connected from the detergent box 80, the water inlet pipe of the outer cylinder, the outer cylinder, the drain pipe, etc. The washing water containing detergent enters the foam generator 1 by its own gravity or by water pump.

[0137] S4 - Air Pump 60 and Ozone Generator Foaming: Air pump 60 is turned on, allowing gas to enter the foam generating device 1. With the participation of washing water containing detergent, foaming is completed through a porous, mesh foamer or a negative pressure jet device. Preferably, the gas used for foaming is ozone or other gases with antibacterial properties. During this process, the inner drum of the garment treatment drum 90 should be rotated intermittently to ensure better foam coverage of the garment surface.

[0138] S5 - Selective opening of spray inlet valve 1001 to enhance foaming: The user or the washing machine can selectively open the spray inlet valve 1001, and use high-speed liquid flow to impact the washing water through the jet holes on the spray head 1002 to enhance the foaming rate and foam production, while improving a certain fluidity, so that the foam can be better sprayed onto the clothes in the drum and the observation window, resulting in better foaming visual effect and sterilization effect.

[0139] S6 - Turn off air pump 60 and ozone generator: When the washing water in foam generating device 1 is consumed, or after a certain amount of consumption, turn off air pump 60 and ozone generator so that new washing water can be added to foam generating device so that foaming can continue.

[0140] S7 - Repeat S3-S6 to reach the set number of times: Repeat the liquid feeding, foaming, and spraying process until the set number of times is reached. Preferably, the set number of foaming times is set according to the consumption of high-concentration washing water in the clothes treatment drum 90, that is, the concentration value of the detergent, and the achievement of the sterilization effect.

[0141] S8 - Regular Wash, Rinse, and Spin-Dry: After completing the foaming sterilization wash, the system enters the regular wash mode, which includes washing, rinsing, and spin-drying. During the regular wash, the S3-S6 foaming sterilization wash process can be added as needed by the user or controlled automatically by the washing machine to achieve a better foam sterilization effect.

[0142] Preferably, the foam generator adopts a three-chamber design, and the specific design scheme and control process are as follows:

[0143] Taking a drum washing machine as an example, the washing machine includes a body, detergent dispenser 80, display control panel, outer drum, inner drum, heating tank 200, first pipe 300, second pipe 500, water pump 400, emergency drain outlet 700, main wash water inlet valve 801, spray water inlet valve 1001, main wash water inlet pipe 802, foam generating device 1, foam delivery pipe 302, and other components. Figure 1 and Figure 2 As shown.

[0144] The aforementioned foam generating device is enclosed by a foam generating device 1 housing and is equipped with several liquid inlet, air inlet, liquid outlet, and air outlet ports. Internally, it is divided into three chambers: a liquid inlet chamber 10, a liquid outlet chamber 20, and a foam chamber 30. A siphon device 50 is installed between the liquid outlet chamber 20 and the foam chamber 10. A liquid inlet 101 is located at the bottom of the liquid inlet chamber 10, connected to the washing water container or pipeline inside the washing machine via a liquid inlet check valve 104 and a liquid inlet pipe. A foaming device is also located at the bottom of the liquid inlet chamber 10, connected to an air pump 60 via an air inlet check valve 104 and an air outlet pipe 103. A spray head 1002 with one or more small holes is located at the top of the liquid inlet chamber 10, capable of high-speed water jetting to impact the liquid surface of the liquid inlet chamber 10, enhancing the foaming effect. The spray head 1001 is connected to a spray inlet valve 1001 via a spray inlet pipe 100. The bottom of the foam chamber 301 is provided with a foam discharge port 301, which is connected to the foam nozzle through a foam delivery pipe 302. For example... Figure 1 and Figure 2 As shown.

[0145] The operating control logic and parameter settings for foam generator 1 and washing machine are as follows:

[0146] Run the ozone foam wash program: The user selects and runs the foam wash mode;

[0147] Weighing: The inner drum of the garment processing drum rotates to complete the weighing process, and the weight of the garment is calculated as M0;

[0148] Turn on the air pump 60 to drain residual water for a duration Tq0: drain the foam from foam chamber 301, including dissolved foam, water flowing down the chamber wall, and residual water not drained previously. Tq0 ranges from 10s to 40s, preferably from 20s to 30s.

[0149] Detergent dosage, dosage M1: Detergent is added in one go or in batches, dosage M1. M1 ranges from 0.3% to 2% of M0, preferably from 0.7% to 1.2% of M0;

[0150] Open the main wash water inlet valve 801 to allow water to enter, duration Ts: Ts ranges from 5s to 360s, preferably from 20s to 40s;

[0151] Main wash water inlet volume, M2: M2 ranges from 0.5L to 25L, preferably from 2L to 4L;

[0152] Liquid is introduced into the inlet chamber 10. Washing water containing detergent in the clothes treatment drum 90 is drawn into the foam generating device 1 by its own gravity or by the water pump 400. The liquid introduction time Tj is 20s-60s, preferably 30-50s. The single liquid introduction volume is 100ml-1000ml, preferably 300ml-700ml. The volume of the inlet chamber 10 is basically the same as the single liquid introduction volume.

[0153] Residual water in the inlet chamber 10 overflows into the outlet chamber 20: The inlet 101 is located at the bottom of the inlet chamber 10. Using the newly entering washing water containing detergent, residual rinsing water overflows from above the partition plate between the inlet chamber 10 and the outlet chamber 20 into the outlet chamber 20. Preferably, the volume of the outlet chamber 20 is substantially the same as the volume of the inlet chamber 10. The overflow time is substantially the same as the inlet time.

[0154] The siphon device 50 draining time Th: When the liquid level in the drain chamber 20 exceeds the highest point of the siphon channel, under the action of the siphon principle, all the liquid in the drain chamber 20 is discharged into the foam chamber 30. Preferably, the volume of the foam chamber 30 below the siphon inlet is basically the same as the volume of the drain chamber 20. The range of Th is 10s-50s, preferably 20-30s;

[0155] Turn on air pump 60 for duration Tq1: Turn on the ozone generator and air pump 60 to introduce the generated ozone gas into the liquid inlet chamber 10. The ozone gas is then foamed through the aeration module 40, and the resulting foam overflows into the liquid outlet chamber 20 and the foam chamber 30. Simultaneously, the pressure generated by the air intake forces the residual rinsing water previously discharged into the foam chamber 30 out through the foam outlet 301, the foam delivery pipe 302, and the foam nozzle. The subsequently generated foam is also discharged from the foam nozzle. The duration Tq1 for turning on air pump 60 once ranges from 20s to 100s, preferably from 40s to 80s. The foaming time is 20s to 60s, with an additional 20s to 30s reserved for draining the residual water from the foam chamber. The air pump flow rate ranges from 150L / min to 50L / min, preferably from 315L / min to 15L / min.

[0156] Turn on the ozone generator for duration Tq2: Ozone is generated and adheres to the surface and encapsulates within the foam during foam generation, giving the foam a bactericidal effect. Tq2 can be the same as Tq1, or 20-40 seconds shorter than Tq1.

[0157] The inner drum of the garment treatment drum 90 rotates for a duration Tt: the inner drum should rotate intermittently so that the foam can better cover the surface of the garment, and the rotation time Tt should be consistent with Tq1;

[0158] Open the spray inlet valve 1011 to spray into the liquid chamber 10 for a duration Tp: high-speed spraying of foaming washing water onto the surface through small holes enhances the foaming effect. The spray water flow rate ranges from 0.2L / min to 4L / min, preferably from 0.5L / min to 1.5L / min. Tp should be 20-30 seconds shorter than Tq1. To prevent the spray water from rapidly diluting the foaming washing water, an intermittent spraying method can be adopted, with an on / off ratio between 1:5 and 5:1, preferably between 1:2 and 2:1.

[0159] Air pump 60 and ozone generator are turned off: After air pump 60 is turned off, there is no air pressure in the foam generating device, and the washing water in the drum can reliably enter the foam generating device by its own gravity. The turning-off time is the same as the liquid inlet time Tj;

[0160] Multiple foaming cycles: Repeat the processes of liquid inlet, overflow, siphon, foaming, spraying, and draining until the set number of cycles N is reached. The set number of foaming cycles is determined based on the consumption of high-concentration washing water in the drum, i.e., the concentration of detergent, and the achievement of sterilization effect. The range of liquid inlet cycles N is 1-20 times, preferably 4-10 times.

[0161] Check water level and replenish water: Check whether the water level inside the laundry drum has reached the optimal set water level. If the water level is insufficient, replenish water to the optimal water level.

[0162] Heated main wash: Turn on the electric heater to heat the washing water to the set temperature for the main wash, which will achieve better cleaning and sterilization.

[0163] Ozone gas / foam enhanced sterilization: During subsequent washing processes, users can choose to repeatedly add liquid to generate foam and add it to the washing drum to enhance foam sterilization;

[0164] Drainage, main spin, rinsing, and final spin: After completing the foaming and sterilization washing, it enters the regular washing mode, which includes washing, rinsing, and spin-drying processes.

[0165] Turn on the air pump for 60 seconds to drain residual water for a duration of Tq0. Drain the residual water in the foam chamber for 30 seconds. The start time should be consistent with the initial residual water draining time Tq0.
