Because the arrangement mode of the outer cylinder and the inner cylinder is canceled, the dirt remained in the washing cylinder can be conveniently removed; and the washing machine can have a large washing capacity at the same volume.

In view of the above, an embodiment of the present application is directed to providing a washing machine, in which an air pump is provided to communicate with a washing tub, and air can be filled into the washing tub by using the air pump during dehydration to increase the pressure inside the washing tub; because the drainage pipeline is communicated with the washing drum, the pressure in the drainage pipeline is also increased, and under the action of the gas pressure, the water in the drainage pipeline can be pressed out by overcoming the action of centripetal force, thereby realizing smooth dehydration.

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 1, the present embodiment provides a washing machine, comprising: the washing machine comprises a machine shell 100, a washing drum 200, an air pump 300 and a drainage pipeline, wherein the washing drum 200 is rotatably arranged in the machine shell 100, the air pump 300 is communicated with the washing drum 200, a rotating shaft is arranged at the first end of the washing drum 200, the first end of the drainage pipeline is communicated with the washing drum 200, and the second end of the drainage pipeline is communicated with the outside of the machine shell 100 after penetrating through the rotating shaft.

Specifically, the casing 100 of the present embodiment may have a prismatic shape or a cylindrical shape, and the specific shape may be set as needed. The casing 100 may be made of metal, for example, stainless steel, so as to improve the strength of the whole machine. A cavity is formed in the cabinet 100 to facilitate the installation of other components. The tub 200 may have a generally cylindrical shape, and a washing space is formed inside the tub 200. In this embodiment, the sidewall of the washing tub 200 is designed to be non-porous, and the washing water and the laundry to be washed can be simultaneously placed in the washing tub 200; that is, the washing tub 200 of the present embodiment can simultaneously function as the inner tub and the outer tub of the related art, so that the dirt remaining in the washing tub 200 can be removed more conveniently; and the washing machine of the present embodiment can have a large washing capacity under the same volume of the cabinet 100. A base is further provided in the cabinet 100, and a first end of the washing tub 200 is provided on the base. The base may be provided with a driving motor and a rotating shaft connected with the driving motor, and the rotating shaft is connected with the first end of the washing drum 200 to drive the washing drum 200 to rotate in the casing 100.

Preferably, the rotation shaft in the present embodiment is hollow, and water inlet and drainage of the washing machine can be performed through the rotation shaft, thereby saving space inside the cabinet 100. For example, a first end of a drain pipe of the washing machine may communicate with the tub 200, and a second end of the drain pipe may communicate with the outside of the cabinet 100 after passing through the rotation shaft, thereby draining wash water in the tub 200 out of the cabinet 100. In order to facilitate the discharge of the washing water, the present embodiment is further provided with an air pump 300, and the air pump 300 is also communicated with the inside of the tub 200, so that air can be pumped into the tub 200 to increase the pressure in the tub 200 and the drain pipe communicated with the tub 200, thereby pressing the washing water out of the drain pipe during the dehydration and drainage processes.

As can be seen from the above description, the washing machine of the present embodiment can charge air into the tub 200 by using the air pump 300 during dehydration to increase the pressure inside the tub 200; because the drainage pipeline is communicated with the washing drum 200, the pressure in the drainage pipeline is also increased, and under the action of the gas pressure, the water in the drainage pipeline can be pressed out against the action of centripetal force, so that smooth dehydration is realized.

It will be appreciated that the specific parameters of the air pump 300 in this embodiment may be selected according to the overall structure of the washing machine, the rotational speed of dehydration, etc. When the pressure provided by the air pump 300 is sufficiently large, the dehydration and drainage processes of the washing machine can be achieved using only the air pump 300.

In other possible embodiments, the drain pipe of the present embodiment may further be provided with a drain pump 440, and during the draining process, the drain pump 440 is used to pump the washing water in the washing tub 200. The drain pump 440 may work together with the air pump 300 during the dehydration process, thereby facilitating smooth dehydration of laundry.

In one possible implementation, the rotating shaft of the present embodiment includes a first sub-rotating shaft 210 and a second sub-rotating shaft 220 that are coaxially disposed, and the first sub-rotating shaft 210 and the second sub-rotating shaft 220 are hollow shafts, so that air and water can pass through conveniently. Specifically, a through hole for communicating the washing tub 200 is provided in the first sub-rotation shaft 210, the air pump 300 is communicated with the washing tub 200 through the through hole, and air pumped by the air pump 300 can enter the washing tub 200 after passing through the first sub-rotation shaft 210. An annular space is formed between the first sub-rotating shaft 210 and the second sub-rotating shaft 220, and a drain pipe is communicated with the outside of the cabinet 100 after passing through the annular space, and wash water discharged from the inside of the tub 200 may be discharged to the outside of the cabinet 100 after passing through the annular space between the first sub-rotating shaft 210 and the second sub-rotating shaft 220.

Further, the drain pipe of the present embodiment includes a first drain pipe 410, a second drain pipe 420, and a third drain pipe 430 which are communicated with each other. As shown in fig. 1, the washing tub 200 of the present embodiment is horizontally disposed in the cabinet 100, and a plurality of drain holes are provided at a first end of the washing tub 200 in a horizontal direction, and are uniformly distributed along a circumferential direction of an end face of the first end of the washing tub 200. The first drain pipe 410 is in communication with the plurality of drain holes and is disposed along a circumference of the first end of the tub 200; that is, the first drain pipe 410 is generally circular in shape so as to receive the washing water discharged from the plurality of drain holes. The second drain pipe 420 has both ends respectively communicating with the first drain pipe 410 and the annular space, and the second drain pipe 420 serves to introduce the washing water in the first drain pipe 410 into the annular space. Both ends of the third drain pipe 430 are respectively connected to the annular space and the outside of the cabinet 100, and the third drain pipe 430 is used to drain the washing water in the annular space to the outside of the cabinet 100.

Further, the drain pump 440 of the present embodiment may be disposed on the third drain pipe 430, and since the first drain pipe 410 and the second drain pipe 420 are disposed between the tub 200 and the rotation shaft, the space is narrow, and it is inconvenient to install the drain pump 440. And the space at the third drain pipe 430 is large, thereby facilitating the installation of the drain pump 440.

In one possible embodiment, the present embodiment further includes a water inlet pipe 500, a first end of the water inlet pipe 500 is communicated with the outside of the cabinet 100, a second end of the water inlet pipe 500 is communicated with the washing tub 200 through a through hole, and the air pump 300 is communicated with the water inlet pipe 500.

As can be seen from the above description, when water is introduced into the washing machine of the present embodiment, the water introduced from the water inlet pipe 500 can be introduced into the inside of the washing tub 200 through the first sub-rotation shaft 210, thereby achieving water introduction of the washing machine.

When the washing machine is drained, the water in the washing tub 200 flows into the first drain pipe 410 through the drain hole by the drain pump 440, and is then discharged to the outside of the cabinet 100 through the second drain pipe 420, the annular space, and the third drain pipe 430.

When the rotation speed of the tub 200 is low (e.g., when the rotation speed is 300 rpm or less) when the washing machine is dehydrating, the washing water in the tub 200 may be discharged only by the drain pump 440. When the rotational speed of the drum 200 increases, the washing water in the first drain pipe 410 is excessively subjected to the centripetal force, so that the drain pump 440 cannot pump the washing water in the first drain pipe 410, and at this time, the air pump 300 can be opened to charge air into the drum 200 to increase the pressure in the first drain pipe 410, so that the water in the first drain pipe 410 is pressed into the second drain pipe 420 against the centripetal force, and then is discharged to the outside of the cabinet 100 through the annular space and the third drain pipe 430.

Further, the air pump 300 of the present embodiment is disposed in the cabinet 100, and the air pump 300 is communicated with the water inlet pipe 500 through the air outlet pipe 310, that is, the air inflation and water inlet of the present embodiment are finally introduced into the washing tub 200 through the water inlet pipe 500. Because the water inlet and the water dehydration are two independent procedures, the same water inlet pipe 500 is adopted to be communicated with the washing drum 200, and the space can be further saved on the premise of not influencing the water inlet and the water dehydration.

Further, the water inlet pipe 500 of the present embodiment is provided with a three-way valve, a first end of the three-way valve is communicated with the air outlet pipe 310, and a second end and a third end of the three-way valve are communicated with the water inlet pipe 500. By arranging the three-way valve, the three-way valve can be connected to the main board of the washing machine, so that the air pump 300 and the water inlet pipe 500 are conducted or only the water inlet pipe 500 is conducted according to a control instruction sent by the main board, and the dehydration or water inlet of the washing machine is realized.

Optionally, the present embodiment further comprises a water inlet valve 510, the water inlet valve 510 being arranged between the first end of the water inlet pipe 500 and the second end of the three-way valve. The water inlet valve 510 is also communicatively connected to the main board of the washing machine, thereby controlling the water inlet of the washing machine.

In an alternative embodiment, the present embodiment further includes a bracket 600, and a shock absorbing device 610 is provided between the bracket 600 and the cabinet 100, and the drum 200 is rotatably provided in the bracket 600. Since the design without the outer tub is adopted, the shock absorbing device 610 is installed between the bracket 600 and the cabinet 100, so that the shock generated when the washing tub 200 rotates can be buffered, the collision between the washing tub 200 and the cabinet 100 during the dehydration process can be prevented, and the smooth progress of the dehydration process can be ensured.

In an alternative embodiment, the second end of the tub 200 of the present embodiment is provided with a tub door 230, the tub door 230 is in communication with the inside of the tub 200, and the tub door 230 may be mounted to the tub 200 in a hinged connection, and the tub door 230 is sealed from the tub 200 during washing, thereby preventing wash water from being sprayed. The cabinet 100 is provided with a door 110 corresponding to the drum door 230, the door 110 can be opened or closed with respect to the cabinet 100, and the door 110 can be mounted on the cabinet 100 in a hinge connection manner, thereby facilitating the user to put in or take out laundry.

In summary, the air pump 300 may be used to fill air into the washing tub 200 during dehydration of the washing machine of the present embodiment, so as to increase the pressure inside the washing tub 200; because the drainage pipeline is communicated with the washing drum 200, the pressure in the drainage pipeline is also increased, and under the action of the gas pressure, the water in the drainage pipeline can be pressed out against the action of centripetal force, so that smooth dehydration is realized.
