Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a foam generating device and clothing processing equipment. Background Art

[0002] The traditional foam generating device only has a liquid inlet chamber and a foam chamber. A foamer is arranged in the liquid inlet chamber for foaming the foaming liquid in the liquid inlet chamber. The foam generated in the liquid inlet chamber will automatically enter the foaming chamber and be input to the designated position through the foaming outlet of the foaming chamber.

[0003] However, when this foam generating device is in use, after the foaming of the foaming liquid in the liquid inlet chamber is completed, a portion of foaming liquid with lower concentration will remain at the bottom of the liquid inlet chamber. If this portion of foaming liquid with lower concentration is not discharged, this portion of foaming liquid with lower concentration will mix with the high-concentration foaming liquid entering the liquid inlet chamber again, thereby affecting the next foaming effect. If this portion of foaming liquid with lower concentration is discharged into the foam chamber, the foaming liquid entering the foam chamber will block the foam discharge port of the foam chamber, thereby affecting the foam delivery effect of the foam chamber. Summary of the invention

[0004] In order to overcome the problem that the foam generating device in the prior art cannot effectively treat the residual foaming liquid in the liquid inlet chamber, the embodiment of the present invention proposes a foam generating device and a clothing processing device, which is provided with a liquid inlet chamber, a liquid discharge chamber and a foaming chamber in the foam generating device, and the liquid inlet chamber and the liquid discharge chamber are arranged adjacent to each other, and the liquid discharge chamber and the foaming chamber are arranged adjacent to each other, and the liquid inlet port of the liquid inlet chamber is arranged at the bottom, so that the foaming liquid can enter the liquid inlet chamber from the bottom of the liquid inlet chamber for foaming treatment, and the foamed foam can enter the liquid discharge chamber and the foaming chamber in turn through the top of the liquid inlet chamber, and finally Finally, it is discharged to the designated position through the bubble discharge port of the foaming chamber. When the foaming liquid in the liquid inlet chamber is consumed, the foaming liquid can enter the liquid inlet chamber again through the liquid inlet port at the bottom of the liquid inlet chamber. Since the liquid enters from the bottom of the liquid inlet chamber, the foaming liquid that enters the liquid inlet chamber again can discharge the low-concentration foaming liquid remaining at the bottom of the liquid inlet chamber after the last foaming is completed into the discharge chamber adjacent to the liquid inlet chamber for storage, thereby avoiding low-concentration foaming liquid from entering the foaming chamber and blocking the bubble discharge port of the foaming chamber, thereby ensuring the foaming effect of the liquid inlet chamber while ensuring the exhaust effect of the foam chamber.

[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0070] The existing foam generating devices are currently unable to effectively process the residual foaming liquid in the liquid inlet chamber. The embodiments of the present invention propose a foam generating device and a clothing processing device, which are configured with a liquid inlet chamber, a liquid discharge chamber and a foaming chamber in the foam generating device, and the liquid inlet chamber and the liquid discharge chamber are adjacent to each other, and the liquid discharge chamber and the foaming chamber are adjacent to each other, and the liquid inlet port of the liquid inlet chamber is configured at the bottom, so that the foaming liquid can enter the liquid inlet chamber from the bottom of the liquid inlet chamber for foaming treatment, and the foamed foam can enter the liquid discharge chamber and the foaming chamber in turn through the top of the liquid inlet chamber, and finally be discharged to a designated position through the foaming port of the foaming chamber. After the foaming liquid in the liquid chamber is consumed, the foaming liquid can enter the liquid inlet chamber again through the liquid inlet at the bottom of the liquid inlet chamber. Since the liquid enters from the bottom of the liquid inlet chamber, the foaming liquid that enters the liquid inlet chamber again can discharge the low-concentration foaming liquid remaining at the bottom of the liquid inlet chamber after the last foaming is completed into the discharge chamber adjacent to the liquid inlet chamber for storage, thereby preventing low-concentration foaming liquid from entering the foaming chamber and blocking the foaming port of the foaming chamber, thereby ensuring the foaming effect of the liquid inlet chamber while ensuring the exhaust effect of the foam chamber.

[0071] The following is combined with Figure 1 -Attached Figure 2 The technical solution of this embodiment is elaborated in detail. In the absence of conflict, the following implementation methods and embodiments can be combined with each other.

[0072] Example

[0073] like Figure 1-Figure 2 As shown, the first aspect of this embodiment provides a foam generating device, and the foam generating device 1 includes:

[0074] The liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other, and the liquid inlet chamber 10 and the liquid discharge chamber 20 are separated at the bottom and connected at the top, and the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other, and the liquid discharge chamber 20 and the foam chamber 30 are separated at the bottom and connected at the top;

[0075] A foaming component, the foaming component includes a foamer 40 disposed in the liquid inlet cavity, and is used to foam the liquid to be foamed in the liquid inlet cavity 10;

[0076] The bottom of the liquid inlet cavity 10 is provided with a liquid inlet 101 , and the bottom of the foam cavity 30 is provided with a bubble outlet 301 .

[0077] In the embodiment of the present invention, a foam generating device is provided with a liquid inlet chamber 10, a liquid discharge chamber 20 and a foaming chamber 30, and the liquid inlet chamber 10 and the liquid discharge chamber 20 are arranged adjacent to each other, and the liquid discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other. At the same time, the liquid inlet port of the liquid inlet chamber 10 is arranged at the bottom, and the bubble discharge port 301 of the foam chamber 30 is arranged at the bottom. The foaming liquid can enter the liquid inlet chamber 10 from the bottom of the liquid inlet chamber 10 and be foamed by the foaming device 40. The foamed foam can enter the discharge chamber 20 and the foaming chamber 30 in turn through the top of the liquid inlet chamber 10, and finally be discharged to the designated action position through the foaming port 301 of the foaming chamber 30. When the foaming liquid in the liquid inlet chamber 10 is consumed, the foaming liquid can enter the liquid inlet chamber again through the liquid inlet port 101 at the bottom of the liquid inlet chamber 10. Since the liquid enters from the bottom of the liquid inlet chamber 10, the foaming liquid that enters the liquid inlet chamber 10 again can discharge the low-concentration foaming liquid remaining at the bottom of the liquid inlet chamber 10 after the last foaming is completed into the discharge chamber adjacent to the liquid inlet chamber 10 for storage, thereby avoiding the low-concentration foaming liquid directly entering the foaming chamber 30 and blocking the foaming port 301 of the foaming chamber 30, thereby ensuring the foaming effect of the liquid inlet chamber 10 while ensuring the foam delivery effect of the foam chamber 30.

[0078] It should be noted that the embodiment of the present invention can ensure that all foam entering the foam cavity 30 is discharged by setting the bubble discharge port 301 of the foam cavity 30 at the bottom, thereby avoiding residual foam in the foam cavity 30 due to the bubble discharge port 301 being set too high.

[0079] It should also be noted that the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 in the embodiment of the present invention may be arranged adjacent to each other in sequence along a certain direction, or may not be arranged adjacent to each other in sequence along a certain direction, as long as the liquid inlet chamber 10 and the liquid discharge chamber 20 are arranged adjacent to each other, and the liquid discharge 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 discharge chamber 20 and the foam chamber 30 are arranged adjacent to each other in sequence along a certain direction.

[0080] Preferably, the bottom surface position of the liquid inlet chamber and the bottom surface position of the foam chamber are both higher than the bottom surface position of the drainage chamber; the top connection position of the liquid inlet chamber 10 and the drainage chamber 20 is higher than the top connection position of the drainage chamber 20 and the foam chamber 30; and a siphon structure is provided between the drainage chamber 20 and the foam chamber 30.

[0081] In some embodiments, Figure 1 and Figure 2 As shown, the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 are all open chambers with a closed bottom and an open top;

[0082] The foam generating device comprises an outer shell, wherein a liquid inlet chamber 10, a liquid discharge chamber 20 and a foam chamber 30 are formed inside the outer shell, and a top channel is defined between the outer shell and the top of the liquid inlet chamber 10, the top of the liquid discharge chamber 20, and the top of the foam chamber 30;

[0083] The top channel enables the liquid inlet chamber 10 and the liquid discharge chamber 20 to communicate at the top, and enables the liquid discharge chamber 20 and the foam chamber 30 to communicate at the top.

[0084] In the embodiment of the present invention, by configuring the liquid inlet chamber 10, the liquid discharge chamber 20 and the foam chamber 30 to be open chambers with a closed bottom and an open top, the foam generating device can maximize the effective volume of the liquid inlet chamber 10, the effective volume of the liquid discharge chamber 20 and the effective volume of the foaming chamber when in use.

[0085] At the same time, through the top channel defined between the outer shell of the foam generating device and the liquid inlet chamber 10, the liquid discharge chamber 20, and the foam chamber 30, the foam and / or liquid overflowing from the liquid inlet chamber 10 can only be discharged through the liquid discharge chamber 20 and the foaming chamber 30 in sequence, thereby preventing the foam overflowing from the liquid inlet chamber 10 from flowing to places other than the liquid discharge chamber 20 and the foaming chamber 30, thereby effectively improving the effect of the foam generating device when in use.

[0086] In some embodiments, the foam generating device further comprises:

[0087] The air pump 60 and the gas generator 70 with sterilization function, wherein the air inlet end of the air pump 60 is connected to the gas generator 70 and the exhaust end is connected to the foamer 40.

[0088] In the embodiment of the present invention, a gas generator 70 with a sterilizing effect is provided, so that a gas with a sterilizing effect can be incorporated into the foam when the foam generating device foams, so that when the foam is input to a designated location to process the object to be processed, the object to be processed can also be sterilized.

[0089] Preferably, the gas generator 70 is an ozone generator. Taking the foam generating device disposed in the clothing processing device as an example, the foam generated by the foam generating device can be applied to the clothing in the clothing processing device, thereby improving the washing effect of the clothing, and at the same time, the foam infused with ozone can also sterilize the clothing when in contact with the clothing, thereby further improving the washing effect of the clothing.

[0090] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating device also includes:

[0091] A liquid inlet pipe 102, the outlet of which is connected to the liquid inlet port 101 of the liquid inlet chamber 10, for inputting foaming liquid into the liquid inlet chamber 10;

[0092] An exhaust pipe 103, one end of the exhaust pipe 103 is connected to the foamer 40, and the other end is connected to the air pump 60;

[0093] A bubble delivery pipe 302, the inlet of which is connected to the bubble discharge port 301 of the foam cavity 30, for discharging the foam in the foam cavity 30;

[0094] in;

[0095] A liquid inlet check valve 104 is provided on the liquid inlet pipe 102. The liquid inlet check valve 104 is designed to allow liquid to flow into the liquid inlet cavity 10 through the liquid inlet pipe 102 and to restrict the liquid in the liquid inlet cavity 10 from flowing out through the liquid inlet pipe 102.

[0096] An exhaust check valve 105 is provided on the exhaust pipe 103 , and the exhaust check valve 105 is designed to allow gas to enter the liquid inlet chamber 10 through the exhaust pipe 103 and restrict the liquid in the liquid inlet chamber 10 from being discharged through the exhaust pipe 105 .

[0097] The above shows multiple pipelines on the foam generating device, so that when the foam generating device is installed in a specific device, it can be connected and installed with the device. At the same time, by setting a liquid inlet check valve 104 on the liquid inlet pipe 102, it can be ensured that during the ventilation and foaming process of the foam generating device, the liquid in the liquid inlet chamber 10 will not be discharged through the liquid inlet pipe 102 under the action of air pressure. By setting an exhaust check valve 105 on the exhaust pipe 103, it can be ensured that during the liquid inlet process of the liquid inlet chamber 10, the foaming liquid in the liquid inlet chamber 10 will not enter the air pump 60 and the gas generator 70 through the exhaust pipe 103, so as to avoid damage to the devices.

[0098] In some embodiments, Figure 1 and Figure 2 As shown, the foam generating device also includes:

[0099] The siphon device 50 is disposed between the drainage chamber 20 and the foam chamber 30 and is used to discharge the liquid in the drainage chamber 20 into the foam chamber 30 when the liquid level in the drainage chamber 20 reaches a preset liquid level.

[0100] In the embodiment of the present invention, a siphon device is provided between the drainage chamber 20 and the foaming chamber 30. When the liquid level in the drainage chamber 20 exceeds the highest point of the siphon channel, the liquid in the drainage chamber 20 is completely discharged into the foam chamber 30 under the action of the siphon principle, and the liquid in the foam chamber 30 can be discharged by supplying air and pressurizing the foam generating device.

[0101] In some embodiments, Figure 1 and Figure 2 As shown, the volume of the liquid inlet chamber 10, the volume of the liquid discharge chamber 20 and the setting position of the siphon device are designed as follows: after all the liquid in the liquid inlet chamber 10 is discharged into the liquid discharge chamber 20, the liquid level position of the liquid discharge chamber 20 is higher than the height of the siphon apex of the liquid discharge chamber of the siphon device 50, that is, the siphon effect can be triggered only when the liquid level of the liquid discharge chamber exceeds the siphon apex, so that the liquid in the liquid discharge chamber can be smoothly discharged into the foam chamber, and the suction end of the siphon device 50 located in the liquid discharge chamber 20 is arranged close to the bottom of the liquid discharge chamber 20, and the volume of the liquid discharge 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 the liquid in the liquid discharge chamber can be completely discharged into the foam chamber.

[0102] In some embodiments, the foam generating device further comprises:

[0103] A spray water inlet pipe 100, on which a spray water inlet valve 1001 is provided, and a spray head 1002 is provided at the water outlet end of the spray water inlet pipe 100;

[0104] The shower head corresponds to the top opening position of the liquid inlet cavity 10 .

[0105] In this way, during the ventilation and foaming process of the foam generating device, the spray water inlet valve 1001 can be opened to allow the spray head 1002 to eject a high-speed water flow to impact the foaming liquid in the liquid inlet chamber 10, thereby promoting foaming and increasing the amount of foam.

[0106] like Figure 1 and Figure 2 As shown, the second aspect of this embodiment further provides a clothes processing device, which includes the foam generating device 1 provided in the first aspect of this embodiment, and the clothes processing device includes a clothes processing drum 90 for accommodating clothes;

[0107] The liquid inlet 101 of the foam generating device 1 is used for receiving washing water from the laundry treatment tub and foaming the washing water, and the foam outlet 301 of the foam generating device 1 is used for inputting the foamed foam into the laundry treatment tub 90 .

[0108] That is, the foam generating device provided in the first aspect of the above embodiment is applied to a clothing processing device, and is used to foam the washing liquid in the clothing when the clothing processing device washes the clothing, and then discharge it into the clothing processing device, so as to improve the washing effect of the clothing processing device on the clothing.

[0109] In some embodiments, a laundry treatment apparatus comprises:

[0110] A detergent box 80, one end of which is connected to a main wash water inlet valve 801, and the other end of which is connected to a clothes treatment drum 90 through a main wash water inlet pipe 802, for discharging the wash water mixed with the detergent in the detergent box 80 into the clothes treatment drum 90;

[0111] A drain port, which is used to discharge the washing water in the laundry treatment drum into the liquid inlet chamber 10 of the foam generating device;

[0112] The bubble delivery pipe 302 in the foam generating device is connected to the clothes processing tub 90 so as to be able to input the foam generated by the foam generating device into the clothes processing tub 90 .

[0113] Furthermore, the drain pipe includes a first drain pipe 300, a second drain pipe 500 and a third drain pipe 600. One end of the first drain pipe 300 is connected to the clothing processing equipment, and the other end is connected to the water inlet end of the water pump 400. The drainage end of the water pump 400 is connected to the second drain pipe 500 and the third drain pipe 600. Preferably, the first drain pipe 300 is provided with a threaded section to reduce the vibration and noise generated during the drainage process.

[0114] One of the second drain pipe 500 and the third drain pipe 600 is connected to the liquid inlet 101 of the foam generating device, and an emergency drain port 700 is provided on the drain pipe connected to the liquid inlet 101 .

[0115] That is, in the embodiment of the present invention, the drain pipe connected to the liquid inlet 101 of the foam generating device is arranged at the position of the emergency drain port 700 of the clothing processing equipment, so that the installation and removal of the drain pipe are facilitated.

[0116] Furthermore, in some embodiments, the laundry processing device further comprises:

[0117] A heating tank 200 provided at the bottom of the laundry processing tub 90;

[0118] The heating tank 200 is disposed at the water inlet end of the first drain pipe 300 that is connected to the laundry processing tub.

[0119] In the embodiment of the present invention, by setting the heating tank 200 at the water inlet end of the first drain pipe 300 connected to the clothes processing drum, the heated washing water can be guided into the liquid inlet chamber 1 of the foam generating device 1, thereby further improving the foaming effect of the foam generating device.

[0120] In some embodiments, Figure 1 and Figure 2 As shown, in this embodiment, the foam generating device is arranged below the clothes processing drum 90;

[0121] The clothes treatment drum 90 is in communication with the liquid inlet 101 and the bubble outlet 302 of the foam generating device 1 to form a circulation passage with the foam generating device 1;

[0122] The clothes treatment drum 90 and the foam generating device 1 constitute a circulation path. When the air pump 60 is turned off, the washing water in the clothes treatment drum 90 can enter the liquid inlet chamber 10 under the action of gravity. When the air pump 60 is turned on, the washing water in the clothes treatment drum 90 stops entering the liquid inlet chamber 10, and the foam generator 40 can foam the washing water in the liquid inlet chamber 10. The foam and / or washing water entering the foaming chamber 30 can be discharged into the clothes treatment drum 90 under the action of air pressure.

[0123] It should be noted that, since the foam generating device 1 and the clothing treatment drum 90 form a circulating passage, when the air pump 60 is turned off, there is no intake pressure in the foam generating device. At this time, the washing water in the clothing treatment drum 90 can enter the liquid inlet chamber 10 of the foam generating device by its own gravity. When the air pump 60 is turned on, since there is intake pressure in the foam generating device 1, the washing water in the clothing treatment drum 90 cannot enter the liquid inlet chamber 10 of the foam generating device 1 by its own gravity due to the pressure difference. At this time, the foam generated by the foam generating device 1 can be pressed into the clothing treatment drum 90 under the action of the intake pressure. At the same time, if there is washing water in the foam cavity, the washing water in the foam cavity 30 can also be pressed into the clothing treatment drum 90 through the bubble discharge port 301 under the action of the pressure difference.

[0124] That is, after the clothes treating device in the second aspect of this embodiment is installed with the foam generating device provided by the first aspect of the embodiment, it can rely on the gravity of the washing water in the clothes treating drum 90 to enter the liquid inlet chamber 10 of the foam generating device 1, and can replace the residual water in the liquid inlet chamber 10 to the liquid discharge chamber 20 for buffering, so as to keep the foam chamber 30 free of water and the exhaust port at the bottom of the foam chamber 30 unobstructed, so that water can continue to enter. If the liquid discharge chamber 20 is not provided, water enters the foam chamber 30 and seals the exhaust port, and this part of water cannot be discharged by gravity {but due to the height requirements of the clothes treating device, the height difference between the clothes treating drum 90 and the foam generating device 1 is not enough}, and the air pump 60 can only be turned on to pressurize the water out, and at this time, the foam generating device 1 cannot enter water.

[0125] Further, in some embodiments, the clothes processing device has a washing program, and the clothes processing device also includes:

[0126] A controller, the controller is used to control the opening of the air pump 60, so as to control whether water enters the liquid inlet cavity 10 by opening and closing the air pump 60;

[0127] When the laundry processing device performs a washing program, the air pump 60 is controlled to be periodically turned off and on according to a preset first cycle, wherein the first cycle includes a first time length when the air pump 60 is in the turned-off state and a second time length when the air pump 60 is in the turned-on state;

[0128] in

[0129] During the first period of time when the air pump 600 is turned off, 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 time period when the air pump 600 is turned on, the amount of water consumed by the foamer 40 during the second time period is not less than the amount of water inlet into the liquid inlet chamber 10 during the first time period.

[0131] That is, in the embodiment of the present invention, by reasonably controlling the opening of the air pump 60, on the one hand, the automatic water inlet effect and the automatic water inlet stop effect of the foam generating device can be achieved, and on the other hand, the water inlet amount of the foam generating device 1 can be reasonably controlled, thereby ensuring the automatic water inlet and stop effects while improving the foaming effect of the foam generating device 1, thereby improving the washing effect of the clothing processing equipment on the clothes.

[0132] Preferably, during the first time period when the air pump 600 is turned off, the amount of water entering the liquid inlet chamber 10 is equal to the volume of the liquid inlet chamber 100; in this way, the high-concentration washing liquid entering the liquid inlet chamber 10 during the first time period can completely discharge the low-concentration washing liquid remaining at the bottom of the liquid inlet chamber 10 after the last foaming is completed into the liquid discharge chamber 20, thereby improving the foaming effect of the washing liquid in the liquid inlet chamber 10.

[0133] Preferably, during the second time period when the air pump 600 is turned on, the amount of water consumed by the foamer 40 during the second time period is equal to the amount of water inlet into the liquid inlet chamber 10 during the first time period. In this way, the foamer 40 can completely foam the washing liquid in the liquid inlet chamber 10 during the second time period, thereby fully foaming the washing liquid in the liquid inlet chamber 10 during the second time period, and then maximally foaming the washing liquid in the laundry treatment drum 90 during the washing time under the washing program, thereby maximizing the washing effect on the laundry.

[0134] In some embodiments, the above-mentioned clothing processing device is preferably a washing machine or a washer-dryer.

[0135] In order to further understand the working principle of the clothes processing device in this embodiment, the clothes processing device is taken as a washing machine and combined with Figure 1 and Figure 2 To explain in detail:

[0136] The operation modes of the foam generating device 1 and the washing machine are as follows:

[0137] When the user selects and runs the foam washing mode, after weighing, the main wash water inlet valve 801 opens to inlet water, and the detergent in the detergent box 80 is flushed into the outer drum of the clothes treatment drum 90 through the main wash water inlet pipe 802, forming washing water containing detergent, and accumulating at the bottom of the outer drum and the heating tank 200. Under the action of gravity, the washing water enters the water pump 400 through the first drain pipe 300 between the heating tank 200 and the water pump 400, and a branch is separated from the emergency drain port 700, that is, the third drain pipe 600 communicated with the liquid inlet chamber 10 of the foam generator 1 enters the liquid inlet chamber 10. At the same time, the gas in the foam generator 1 is discharged from the foam nozzle to the inner drum of the clothes treatment drum 90 through the bubble discharge port 301 and the bubble delivery pipe 302 at the bottom of the foam chamber 30 under the action of the water inlet pressure, ensuring smooth liquid inflow of the foam generating device 1.

[0138] The liquid inlet 101 needs to be arranged at the bottom of the liquid inlet chamber 10. Because before the liquid inlet chamber 10 is filled with liquid, there may be residual rinsing water from the last rinse in the previous operation, and since the detergent concentration in the rinsing water is extremely low, ventilation and foaming cannot be achieved. The bottom liquid inlet can use the newly entered washing water containing detergent to overflow the residual rinsing water from the partition between the liquid inlet chamber 10 and the liquid discharge chamber 20 into the liquid discharge chamber 20. At this time, the bubble discharge port 301 of the foam chamber 30 still remains unobstructed.

[0139] When the liquid level in the drainage chamber 202 exceeds the highest point of the siphon channel, the liquid in the drainage chamber 202 is completely discharged into the foam chamber 30 under the action of the siphon principle.

[0140] Turn on the ozone generator and the air pump 60, and introduce the generated ozone gas into the liquid inlet chamber 10, and foam it through the foamer. The generated foam overflows into the liquid discharge chamber 20 and the foam chamber 30. At the same time, the pressure generated by the intake air discharges the residual rinsing water previously discharged into the foam chamber 30 through the bubble discharge port 301, the bubble delivery pipe 301 and the foam nozzle, and the foam generated subsequently is also discharged from the foam nozzle.

[0141] The purpose of the bubble discharge port 301 disposed at the bottom of the foam cavity 30 is to discharge the excess gas in the cavity when liquid is introduced, and to discharge the residual rinsing water by pressurizing the air intake.

[0142] The function of the liquid inlet one-way valve 104 is that during the ventilation and foaming process, the liquid in the liquid inlet chamber 10 will not return to the clothing processing tub 90 through the liquid inlet pipe 102 under the action of air pressure.

[0143] The function of the exhaust check valve 105 is that, during the liquid inlet process of the liquid inlet chamber 10, the washing water will not enter the air pump 60 and the ozone generator from the liquid inlet pipe 102 to cause damage to the devices.

[0144] During the ventilation and foaming process, the spray water inlet valve 1001 can be opened to allow the spray head 1002 to emit a high-speed water flow to impact the washing liquid in the liquid inlet chamber 10, thereby promoting foaming and increasing the amount of foam.

[0145] The liquid level after all the liquid in the liquid inlet chamber 10 overflows into the liquid discharge chamber 20 should be higher than the siphon apex height of the liquid discharge chamber 20 to trigger the siphon effect so that the liquid in the liquid discharge chamber 20 can be smoothly discharged into the foam chamber 30 .

[0146] The bottom of the drainage chamber 20 is higher than the bottom of the foam chamber 30, the siphon device 50 is close to the bottom of the drainage chamber 20 at the suction end of the drainage chamber 20, and the volume of the drainage chamber 20 is not larger than the volume of the foam chamber 30 below the siphon suction end, so that all the liquid in the drainage chamber 20 can be discharged into the foam chamber 30.

[0147] When the washing water in the liquid inlet chamber 10 is completely consumed by foaming, the ozone generator and the air pump 60 are turned off, and the washing water in the outer drum of the clothing treatment device enters the liquid inlet chamber 10 again, and the ozone generator and the air pump 60 are turned on to perform ozone foaming. During the entire main washing process, the liquid inlet foaming process can be repeated multiple times to ensure good cleaning, softening and sterilization effects.

[0148] During the rinsing process, the rinsing water will also enter the liquid inlet chamber 10 through the liquid inlet pipe 102, and the excess will overflow into the liquid discharge chamber 20, and then be discharged into the foam chamber 30 through the siphon device 50. The rinsing water in the foam chamber 30 will be pressed out by ventilation and pressurization, and finally only relatively clear rinsing water will remain in the liquid inlet chamber 10. During the ventilation and pressurization process, the ozone generator can be turned on, and the ozone gas introduced can effectively sterilize the residual water to prevent bacterial growth. The spray water inlet valve 1001 can also be opened to spray clean water, and the liquid inlet chamber 10 and the entire foam generating device 1 are filled with water for cleaning, and then the residual water in the foam chamber 30 is discharged by ventilation and pressurization.
