Problems solved by technology

[0003] However, the above-mentioned non-porous inner drum washing machine has the following problems: the drainage structure is complex, the drainage is not smooth, and the drainage port is not tightly sealed.
The above setting method, because the valve plug is driven by the motor, has the problems of complex structure, poor reliability, and high cost, and the valve plug of the check valve is blocked by lint and debris during the movement process, resulting in the failure of the check valve seal. .

Embodiment 1

[0038] Such as Figure 1 to Figure 3 As shown, this embodiment introduces a washing machine, which includes a drum 2 installed in a casing 1, the drum 2 is a cylindrical structure with an open top and a vertical axis, the two sealed ends of the drum 2, the side The walls are not provided with dehydration holes. The two sealing ends of the drum 2 are respectively installed on the housing 1 via the rotating shaft, and the center of the sealing end at one end of the drum is connected with the driving motor 9 of the washing machine to drive the drum 2 to rotate under the action of the driving motor.

[0039] By setting the drum as a water tank with no dewatering holes and a water storage function, the technical solution of setting a hose at the drain outlet of the drum for controllable drainage can be directly set in the non-porous interior that integrates the functions of the inner bucket and the outer bucket. On the drum washing machine, the purpose of smoothly draining the was...

Embodiment 2

[0053] The difference between this embodiment and the above-mentioned first embodiment is that: at least one sealing end of the drum 2 is provided with a drainage port 21 at the periphery; There are slider 8. The slider 8 is arranged on one side of the hose 5 . The ejector rod constituting the driving device extends horizontally and can move telescopically in the horizontal direction, so that the extended ejector rod drives the slider 8 to push and pull along the outer side of the end of the drum 2 to approach or move away from the hose 5, thereby achieving The purpose of bending the hose controlledly and sealing the drain.

[0054] In this embodiment, a plurality of drain outlets 21 can be evenly distributed on the outer periphery of the sealing end of the drum 2, and each drain outlet 21 is respectively provided with a slider 8 on the side of the same drum rotation direction. During the rotation of the drum 2, each drain The outlets 21 are in the same movement path; the wa...

Embodiment 3

[0056] The difference between this embodiment and the above-mentioned second embodiment is that in this embodiment, in order to improve the drainage efficiency, a plurality of drain outlets 21 can be provided on the drum 2 . The side wall of the drum 2 is arranged with a plurality of drainage ports 21, and each drainage port 21 is connected with the hose 5 passing through the drum 2 respectively, and each drainage port 21 is evenly arranged on the same circumference of any section of the drum 2, so that the drum 2 During the rotation process, the movement paths of each water outlet 21 coincide, and each water outlet 21 is respectively provided with a corresponding slide block 8 towards the second circular rotation direction, so as to simultaneously close or open the soft valve at each water outlet 21 under the action of the driving device. Tube 5.

[0057] In this embodiment, a plurality of drainage outlets 21 are evenly distributed in any radial section of the side wall of th...

Abstract

The invention discloses a drum washing machine which comprises a drum. A water discharging port is formed in the drum, a hose is connected at the water discharging port, extends out of the drum and can generate elastic deformation, a slider is slidably mounted outside the drum, and a driving device is mounted on the washing machine and used for driving the slider to displace to control the sliderand the hose to mutually squeeze and contact until the corresponding hose is bent and deformed to close the water discharging port or drive the slider and the hose to be separated, so that the hose resets under the action of elastic force of the hose to open the water discharging port. The hose is arranged at the water discharging port and bent and deformed under the action of an ejector rod in the rotating process of the drum, so that the water discharging port is closed, water stored in the drum forms washing water flow, and a normal working process of the drum washing machine is executed.

Description

technical field [0001] The invention belongs to the technical field of clothes processing equipment, and in particular relates to a drum washing machine, in particular to a drainage device for a non-porous inner drum washing machine. Background technique [0002] In order to avoid pollution, not easy to breed bacteria, save washing water and other user needs, the existing washing machine adopts the non-porous inner tub technology, which integrates the inner tub and outer tub of the washing machine, so that it has the dual functions of accommodating washing water and rotating to form a washing water flow. effect. Simultaneously, in order to achieve the above object, a single drum needs to be set in the washing machine housing, and the dehydration hole for the water supply flow outflow during the normal washing process is not provided on the drum except the clothes insertion port, and the drum is connected with the washing machine driving motor, so that the drum can generate w...
