[0123] It should be noted that, since the foam generating device 1 and the clothes treatment cylinder 90 form a circulation path, when the air pump 60 is closed, there is no air inlet pressure in the foam generating device, at this time, the washing water in the clothes treatment cylinder 90 can enter the liquid inlet cavity 10 of the foam generating device by its own gravity, and when the air pump 60 is opened, since the foam generating device 1 has air inlet pressure, the washing water in the clothes treatment cylinder 90 cannot enter the liquid inlet cavity 10 of the foam generating device 1 by its own gravity under the action of pressure difference, at this time, the foam generated by the foam generating device 1 can be pressed into the clothes treatment cylinder 90 under the action of air inlet pressure, and if there is washing water in the foam cavity, the washing water in the foam cavity 30 can also be pressed into the clothes treatment cylinder 90 through the foam outlet 301 under the action of pressure difference.

[0124] That is, the laundry treatment apparatus in the second aspect of the embodiment can rely on the self-gravity of the washing water in the laundry treatment drum 90 to feed water into the liquid inlet cavity 10 of the foam generating device 1 after the foam generating device provided in the first aspect of the embodiment is installed, and can replace the residual water in the liquid inlet cavity 10 to the liquid outlet cavity 20 for buffering, keep the foam cavity 30 in a state without water, and the exhaust port at the bottom of the foam cavity 30 is unobstructed, so as to continuously feed water. If the liquid outlet cavity 20 is not provided, the water fed into the foam cavity 30 blocks the exhaust port, and the part of water cannot be discharged by gravity {because the height difference between the laundry treatment drum 90 and the foam generating device 1 is not enough due to the height requirement of the laundry treatment apparatus}, and only the air pump 60 can be opened to pressurize and discharge water, at this time the foam generating device 1 cannot feed water.

[0125] Further, in some embodiments, the laundry treatment apparatus has a washing program, and the laundry treatment apparatus further comprises:

[0126] a controller, the controller being configured to control the opening of the air pump 60 to control whether the liquid inlet cavity 10 feeds water by opening and closing of the air pump 60;

[0127] When the laundry treatment apparatus executes the washing program, the air pump 60 is controlled to be periodically closed and opened according to a first period, wherein the first period includes a first time length during which the air pump 60 is in a closed state and a second time length during which the air pump 60 is in an opened state;

[0128] wherein

[0129] During the first time length in which the air pump 60 is closed, the water feeding amount of the liquid inlet cavity 10 does not exceed the volume of the liquid inlet cavity 10;

[0130] During the second time length in which the air pump 60 is opened, the water consumption amount of the foamer 40 in the second time length is not less than the water feeding amount of the liquid inlet cavity 10 in the first time length.

[0131] That is, in the embodiment of the utility model, by reasonably controlling the opening of the air pump 60, on the one hand, the automatic water feeding effect and the automatic stopping water feeding effect of the foam generating device can be realized, and on the other hand, the water feeding amount of the foam generating device 1 can be reasonably controlled, so that the foaming effect of the foam generating device 1 is improved while the automatic water feeding and stopping water feeding effects are ensured, and then the washing effect of the laundry treatment apparatus on the laundry is improved.

[0132] Preferably, during the first time length in which the air pump 60 is closed, the water feeding amount of the liquid inlet cavity 10 is equal to the volume of the liquid inlet cavity 10; in this way, the high-concentration washing liquid fed into the liquid inlet cavity 10 in the first time length can completely discharge the low-concentration washing liquid remaining in the bottom of the liquid inlet cavity 10 after the last foaming is completed into the liquid outlet cavity 20, so as to improve the foaming effect of the washing liquid in the liquid inlet cavity 10.

[0133] Preferably, the air pump 60 is opened for a second time length, and the water consumed by the foam generator 40 in the second time length is equal to the water inflow of the liquid inlet cavity 10 in the first time length. In this way, the foam generator 40 can completely foam the washing liquid in the liquid inlet cavity 10 in the second time length, so as to sufficiently foam the washing liquid in the liquid inlet cavity 10 in the second time length, and then maximize the foaming treatment of the washing liquid in the clothes treatment drum 90 in the washing time in the washing program, thereby maximizing the washing effect on the clothes.

[0134] In some embodiments, the above-mentioned clothes treatment apparatus is preferably a washing machine or a washer-dryer.

[0135] In order to further understand the working principle of the clothes treatment apparatus in the embodiment, the clothes treatment apparatus is taken as a washing machine, and the operation mode of the washing machine and the foam generator 1 are specifically described as follows in combination with Figure 1 and Figure 2 Figure 1 Figure 2

[0136] The operation mode of the foam generator 1 and the washing machine is as follows:

[0137] When the user selects and runs the foam washing mode, after the weighing is completed, the main washing water inlet valve 801 is opened to inflow water, and the washing agent in the washing agent box 80 is flushed into the outer drum of the clothes treatment drum 90 through the main washing water inlet pipe 802 to form washing water containing the washing agent and accumulate in the outer drum bottom and the heating groove 200. Under the action of gravity, the washing water enters the water pump 400 through the first drainage pipe 300 between the heating groove 200 and the water pump 400, and a branch of the emergency drainage port 700, i.e., the third drainage pipe 600 communicating with the liquid inlet cavity 10 of the foam generator 1, enters the liquid inlet cavity 10. At the same time, the gas in the foam generator 1 is discharged from the foam nozzle into the inner drum of the clothes treatment drum 90 through the bubble discharge port 301 at the bottom of the foam cavity 30 and the bubble conveying pipe 302 under the action of the water inflow pressure, so as to ensure that the foam generator 1 smoothly inflows.

[0138] The liquid inlet port 101 needs to be arranged at the bottom of the liquid inlet cavity 10. Because the liquid inlet cavity 10 may be left with the last rinsing water remaining after the last operation before the liquid inlet cavity 10 inflows, the rinsing water cannot realize aeration foaming due to the extremely low concentration of the washing agent contained in the rinsing water, and the bottom liquid inlet can overflow the rinsing residual water from the separation plate between the liquid inlet cavity 10 and the liquid outlet cavity 20 to the liquid outlet cavity 20 by using the newly-inflowed washing water containing the washing agent. At this time, the bubble discharge port 301 of the foam cavity 30 still maintains an unobstructed state.

[0139] When the liquid level in the liquid outlet cavity 202 exceeds the highest point of the siphon passage, the liquid in the liquid outlet cavity 20 is completely discharged into the foam cavity 30 under the action of the siphon principle.

[0140] ​The ozone generator and the air pump 60 are turned on, the generated ozone gas is introduced into the liquid inlet chamber 10, foaming is carried out through the foaming device, the generated foam overflows into the liquid outlet chamber 20 and the foam chamber 30, at the same time, the pressure generated by the gas inlet causes the residual rinsing water previously discharged into the foam chamber 30 to be discharged through the foam discharge port 301, the foam discharge pipe 301 and the foam nozzle, and then the generated foam is also discharged from the foam nozzle.

[0141] The foam discharge port 301 is arranged at the bottom of the foam chamber 30, which can not only discharge the excess gas in the chamber when the liquid is introduced, but also discharge the residual rinsing water through the gas inlet pressure.

[0142] The liquid inlet one-way valve 104 can prevent the liquid in the liquid inlet chamber 10 from returning to the laundry treatment drum 90 through the liquid inlet pipe 102 under the action of the gas pressure during the gas inlet foaming process.

[0143] The gas outlet one-way valve 105 can prevent the washing water from entering the air pump 60 and the ozone generator from the liquid inlet pipe 102 during the liquid inlet process of the liquid inlet chamber 10, so as to avoid damaging the device.

[0144] During the gas inlet foaming process, the spray water inlet valve 1001 can be turned on to make the spray head 1002 spray high-speed water flow to impact the washing liquid in the liquid inlet chamber 10, so as to promote foaming and increase the amount of foam.

[0145] The liquid level in the liquid inlet chamber 10 after all the liquid in the liquid inlet chamber 10 overflows into the liquid outlet chamber 20 is preferably higher than the height of the siphon top point of the liquid outlet chamber 20, so as to trigger the siphon effect and make the liquid in the liquid outlet chamber 20 be smoothly discharged into the foam chamber 30.

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

[0147] When the washing water in the liquid inlet chamber 10 is foamed and consumed, the ozone generator and the air pump 60 are turned off, the washing water in the outer drum of the laundry treatment device is introduced into the liquid inlet chamber 10 again, the ozone generator and the air pump 60 are turned on, and ozone foaming is carried out. During the whole main washing process, the liquid inlet foaming process can be repeatedly carried out for multiple times to ensure good washing, softening and degerming effects.

[0148] During the rinsing process, the rinsing water also enters the liquid inlet cavity 10 through the liquid inlet pipe 102, the excess part overflows to the liquid outlet cavity 20, and then is discharged to the foam cavity 30 through the siphon device 50. The rinsing water in the foam cavity 30 is pressed out by the aeration and pressurization, and finally only the relatively clear rinsing water remains in the liquid inlet cavity 10. During the aeration and pressurization, the ozone generator can be turned on, and the ozone gas introduced can effectively sterilize the residual water and prevent the growth of bacteria. The spray water inlet valve 1001 can also be opened to spray clean water, and the liquid inlet cavity 10 and the entire foam generating device 1 are washed by water injection, and then the residual water in the foam cavity 30 is discharged by aeration and pressurization.
