The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, the drum washing machine of the present invention mainly comprises a cabinet 1, an outer tub 2, and an inner tub 3. Wherein, the outer cylinder 2 is fixedly arranged in the box body 1 through a tension spring 4 and a damper 5. The inner cylinder 3 is rotatably provided in the outer cylinder 2. The direction of a tank port (not shown) of the tank 1, an outer cylinder port (not shown) of the outer cylinder 2, and an inner cylinder port (not shown) of the inner cylinder 3 is the same.

As shown in fig. 1 to 3, the drum washing machine of the present invention further includes a door device, which mainly includes a first door body 6, a second door body 7 and a connecting device (not shown). The first door body 6 is pivotally connected with the box body 1 and used for closing a box body opening, and the second door body 7 is pivotally connected with the inner barrel 3 and used for closing the inner barrel opening. The first end of the connecting device is fixedly connected with the first door body 6, and the second end of the connecting device can be selectively connected with the second door body 7. It will be appreciated by a person skilled in the art that the number of connecting means may be any feasible number, such as one, two, three, etc.

As shown in fig. 3, the second door body 7 can abut against the inner sidewall of the inner cylindrical opening in the radial direction after being closed, and thus seal the inner cylindrical opening.

As shown in fig. 1 and 2, the coupling means comprises a spring 8 and an electromagnetic lock 9. Wherein, the first end (left end) of the spring 8 is fixedly connected with the inner side of the first door body 6, and the second end (right end) of the spring 8 is fixedly connected with the first end (left end) of the electromagnetic lock 9. The electromagnetic lock 9 is connected with a controller of the drum washing machine through an electric wire.

When the electromagnetic lock 9 is powered on, the second end (right end) of the electromagnetic lock 9 is attracted with the second door body 7, and therefore the first door body 6 and the second door body 7 are fixedly connected together. At this time, when the user opens the first door body 6, the second door body 7 is also opened through the pulling action of the spring 8 and the electromagnetic lock 9. When the user closes the first door body 6, the second door body 7 is also closed by being pushed by the spring 8 and the electromagnetic lock 9.

When the electromagnetic lock 9 is de-energized, the second end of the electromagnetic lock 9 is disconnected from the second door body 7. At this time, the second door 7 can be rotated by the inner cylinder 3 without interfering with the electromagnetic lock 9.

It will be understood by those skilled in the art that the spring 8 is provided in the connection device to allow the connection device to be bent in a horizontal direction, thereby preventing the first door body 6 and the second door body 7 from interfering with each other when they are opened simultaneously. On this basis, the spring 8 may also be replaced by any other feasible flexible member, such as a rubber rod, a spring sheet, etc.

As shown in fig. 2, in order to allow the electromagnetic lock 9 to smoothly engage the second door 7, the second door 7 is provided with an iron 74 as an engaged member. Alternatively, those skilled in the art may use iron for the main body of the second door 7 as required. Alternatively, one skilled in the art may also replace the iron 74 with a magnet, such as a permanent magnet or a soft magnet, as desired.

Further, the skilled person may replace the electromagnetic lock 9 with any other electromagnetic member capable of generating a magnetic force, such as an electromagnetic coil or an electromagnet, as required.

As can be seen from fig. 1 and 2, the drum washing machine of the present invention can connect the first door body 6 and the second door body 7 together through the connection device when the electromagnetic lock 9 is powered on, so that the first door body 6 and the second door body 7 can be opened or closed simultaneously, so that a user can open or close the second door body 7 simultaneously when opening or closing the first door body 6. Furthermore, the drum washing machine of the invention can make the first door body 6 and the second door body 7 independent of each other through the connecting device when the electromagnetic lock 9 is powered off, so that the second door body 7 can rotate freely along with the rotation of the inner drum 3 without interfering with the first door body 6 and the connecting device, thereby improving the stability of the inner drum 3 during rotation and reducing the noise of the inner drum 3 during rotation.

Further, in order to ensure that the first door body 6 and the second door body 7 can be opened simultaneously, the pivoting end of the second door body 7 and the pivoting end of the first door body 6 need to be on the same plane. To this end, the drum washing machine of the present invention is further provided with a positioning means for accurately stopping the inner drum 3 at an angular position at which the pivoting end of the second door body 7 is aligned with the pivoting end of the first door body 6. The positioning means is illustratively an encoder provided on the drive motor to cause the drive motor to brake in time when it is detected that the inner drum 3 is rotated in place. Since the means of locating and locking the inner barrel 3 to the target position is conventional in the art, it will not be described herein in greater detail.

As shown in fig. 4 to 6, the second door body 7 of the present invention mainly includes a body 71, a rubber ring 72, a weight ring 73, and an iron 74. Wherein, rubber ring 72 and counter weight ring 73 constitute the sealing washer of second door body 7 together. The body 71, the rubber ring 72 and the counterweight ring 73 are sequentially arranged from inside to outside along the radial direction, namely, the outer side end of the body 71 is fixedly connected with the inner side end of the rubber ring 72, and the outer side end of the rubber ring 72 is fixedly connected with the inner side end of the counterweight ring 73. The iron 74 is disposed on the left side of the body 71 in fig. 5, and the iron 74 is disposed on the rotational axis of the body 71, corresponding to the connecting means. Further, the number of the irons 74 may be the same as or different from the connecting means, for example, one iron 74 may correspond to at least two connecting means (specifically, the electromagnetic lock 9).

As shown in fig. 5 and 6, the outer end of the rubber ring 72 is provided with an annular groove 721, and both the weight rings 73 are disposed in the annular groove 721. Further, it is also possible for those skilled in the art to omit the provision of the annular groove 721 and to provide the weight ring 73 directly on the outer end of the rubber ring 72, as required.

It will be understood by those skilled in the art that the number of weight rings 73 is not limited to two as shown in the drawings, but may be one, three, four, etc.

It will also be appreciated by those skilled in the art that the rubber ring 72 and the weight ring 73 may be either fixedly attached together or integrally formed.

Further, in the preferred embodiment of the present invention, both the rubber ring 72 and the weight ring 73 are made of a rubber material having elasticity. Alternatively, one skilled in the art may use any other elastic material, such as elastic plastic, elastic resin, etc., for the rubber ring 72 and/or the weight ring 73, as desired.

As shown in fig. 3, 5, and 6, after the second door body 7 of the present invention is closed, the outer end of the weight ring 73 abuts against the inner wall of the inner cylindrical opening of the inner cylinder 3. When the inner cylinder 3 rotates with the second door body 7, the counterweight ring 73 deforms along the radial direction under the action of centrifugal force, so that the outer end of the counterweight ring 73 presses the inner side wall under the action of centrifugal force. And the pressing force of the outer side end of the counterweight ring 73 on the inner side wall is gradually increased along with the increase of the rotating speed of the inner cylinder 3. Effectively ensuring the sealing of the second door body 7 to the inner barrel 3 and preventing the washing water in the inner barrel 3 from flowing out from between the inner barrel 3 and the second door body 7 when the inner barrel 3 rotates at high speed.

Further, in order to make the deformation of the weight ring 73 under the centrifugal force more obvious, the person skilled in the art may arrange the rubber ring 72 into any other feasible annular member, such as an annular air bag, a C-shaped annular member, a V-shaped annular member, etc., as required.

In another possible technical solution of the present invention, a person skilled in the art can arrange the counterweight ring 73 inside the rubber ring 72, and make the outer end of the rubber ring 72 abut against the inner sidewall of the outer cylinder mouth, as required. Further, when the weight ring 73 is provided inside the rubber ring 72, the weight ring 73 may be provided as a weight member of another form. Illustratively, the counterweight ring 73 is replaced by a plurality of arc-shaped counterweights, and the plurality of arc-shaped counterweights are arranged inside the rubber ring 72 along the circumferential direction of the rubber ring 72.

Finally, it should be noted that the circumferential wall of the inner cylinder 3 of the present invention has through holes, and each through hole is configured with a one-way structure. The one-way structure is closed in a normal state, and the washing water in the inner cylinder 3 is not allowed to enter the outer cylinder 2; the one-way structure is opened when the inner tub 3 is rotated at a high speed, allowing the washing water in the inner tub 3 to enter the outer tub 2, so that the dehydrating operation of the washing machine is completed.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
