A washing machine 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 5.
As shown in fig. 1 and 2, a washing machine 100 according to an embodiment of the present invention includes a washing tub 1, an outer tub 2, a door assembly 3, and an air pumping system 4.
Wherein, a washing space 10 is defined in the washing tub 1, the outer tub 2 is arranged outside the washing tub 1, a water storage space 20 is defined between the outer tub 2 and the washing tub 1, the water storage space 20 is communicated with the washing space 10, and the water storage space 20 is communicated with the outside atmosphere. Therefore, the washing water can be injected into the washing tub 1 through the outer tub 2, and the pressure in the water storage space 20 can be always kept in balance with the external atmosphere.
The door assembly 3 is provided on the washing tub 1 to open and close the washing space 10. For example, in some embodiments of the present invention, the top of the washing tub 1 is open, and the door assembly 3 may be disposed at the top of the washing tub 1.
The pumping system 4 includes a pumping duct 41 and a pumping device 42, a first end 411 of the pumping duct 41 is communicated with the pumping device 42, a second end 412 of the pumping duct 41 is adapted to be communicated with the washing space 10, and the pumping device 42 is configured to pump the washing space 10 such that the pressure inside the washing space 10 is less than the external atmospheric pressure. Alternatively, the air-extracting device 42 may be a vacuum pump or the like, but is not limited thereto. Therefore, the washing water in the washing space 10 can move upwards against gravity under the action of pressure difference until the washing water in the water storage space 20 all flows into the washing space 10, at the moment, air flows from the water storage space 20 to the washing space 10 under the action of pressure difference, so that the pressure difference between the water storage space 20 and the washing space 10 is gradually reduced until the gravity of the washing water is greater than the pressure, and at the moment, the washing water falls again under the action of gravity. Due to the fluidity and the discontinuity of the washing water, the washing water flows up and down in the washing space 10 under the action of gravity and pressure, and the clothes are driven by the strong water flow to roll up and down, so that the dirt on the clothes can be removed under the washing of the strong water flow, and the washing effect is achieved.
According to some embodiments of the present invention, the air exhaust system 4 may be disposed separately from the washing tub 1, that is, when air exhaust is required, the second end 412 of the air exhaust pipe 41 may be communicated with the washing space 10, and after washing is finished, the air exhaust system 4 may be separated from the washing tub 1, so that the occupied space of the washing machine 100 may be saved, and storage may be facilitated.
For example, in the initial state, the air pressures in the water storage space 20 and the washing space 10 are equal to each other and are equal to the external atmospheric pressure, and the liquid level of the washing water in the water storage space 20 is equal to the liquid level of the washing water in the washing space 10. During the washing, the air-extracting device 42 extracts air from the washing space 10, so that the air pressure in the washing space 10 is reduced, since the water storage space 20 is communicated with the external atmosphere, the air pressure of the water storage space 20 is always equal to the external atmospheric pressure, so that the air pressure in the washing space 10 is less than the air pressure in the water storage space 20 during the air exhaust process, the washing water in the washing tub 1 moves upward against the gravity under the action of the pressure difference, so that the liquid level of the washing water in the washing space 10 is higher than the liquid level of the washing water in the water storage space 20, when the washing water in the water storage space 20 completely enters the washing space 10, the air passes through the washing water to flow to the space above the washing water under the action of the pressure difference until the gravity of the washing water is greater than the pressure difference between the washing space 10 and the water storage space 20, so that the washing water drops again by gravity, so that the level of the washing water in the washing space 10 drops. Due to the fluidity and the discontinuity of the washing water, the washing water rolls and flows up and down in the washing space 10 under the action of gravity and pressure to wash the clothes, remove stains on the dirty clothes and achieve the washing effect. Therefore, the entanglement of the laundry and the abrasion of the laundry can be reduced, and the washing time is short, thereby greatly reducing the power consumption of the washing machine 100 and reducing the use cost of the washing machine 100.
According to the washing machine 100 of the embodiment of the invention, the air exhaust system 4 is arranged, the air exhaust device 42 of the air exhaust system 4 is used for exhausting air to the washing space 10, and the pressure difference between the water storage space 20 and the washing space 10 is utilized to make the washing water in the washing barrel 1 flow in a rolling manner, so that the clothes can be driven to roll up and down under the action of strong water flow, stains on the clothes can be removed under the washing of the strong water flow, the washing effect is achieved, the winding of the clothes and the abrasion of the clothes in the washing process are reduced, the washing time is short, the power consumption of the washing machine 100 is greatly reduced, and the use cost of the washing machine 100 is reduced.

The washing method of the washing machine 100 according to the embodiment of the present invention is described as follows. Wherein the washing machine 100 may be the washing machine 100 in the above-described embodiment, the washing method of the washing machine 100 includes the steps of:
injecting water into the water storage space 20;
the door body assembly 3 is closed, and the air in the washing space 10 is exhausted by the air exhaust system 4, so that the air pressure in the washing space 10 is smaller than the external atmospheric pressure.
Specifically, the user can inject washing water with a proper water level into the washing space 10 according to the quantity of the laundry, then close the door assembly 3, and exhaust the washing space 10 through the air exhaust device 42 of the air exhaust system 4, so that the air pressure in the washing space 10 is reduced, and the washing water in the washing tub 1 is forced to flow through the pressure difference between the water storage space 20 and the washing space 10.
For example, the washing water may enter the water storage space 20 from the first water inlet 21 and flow toward the washing tub 1 from the second water inlet 11. In the initial state, the air pressures in the water storage space 20 and the washing space 10 are equal to each other and are equal to the external atmospheric pressure, and the liquid level of the washing water in the water storage space 20 is equal to the liquid level of the washing water in the washing space 10.
Because the water storage space 20 is communicated with the outside atmosphere, the air pressure of the water storage space 20 is always equal to the outside atmospheric pressure, so that in the air extraction process, the air pressure in the washing space 10 is smaller than the air pressure in the water storage space 20, the washing water in the washing tub 1 overcomes the gravity to move upwards under the action of pressure difference, when the washing water in the water storage space 20 completely enters the washing space 10, the air passes through the washing water to flow to the space above the washing water under the action of the pressure difference until the gravity of the washing water is larger than the pressure difference between the water storage space 20 and the washing space 10, at the moment, the washing water falls again under the action of the gravity, and the liquid level of the washing water in the washing space 10 is lowered. . Due to the fluidity and the discontinuity of the washing water, the washing water rolls and flows up and down in the washing space 10 under the action of gravity and pressure to wash the clothes, remove stains on the dirty clothes and achieve the washing effect.
According to the washing method of the washing machine 100 of the embodiment of the invention, the washing water in the washing tub 1 is enabled to flow in a strong rolling manner by utilizing the pressure difference between the water storage space 20 and the washing space 10, so that the clothes can be driven to roll up and down under the action of strong water flow, stains on the clothes can be removed under the washing of the strong water flow, the washing effect is achieved, the winding of the clothes and the abrasion of the clothes in the washing process are reduced, the washing time is short, the power consumption of the washing machine 100 is greatly reduced, and the use cost of the washing machine 100 is reduced.
