Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. 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 top-loading 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 disposed within the case 1, and the inner cylinder 3 is pivotally disposed within the outer cylinder 2. The top of the box body 1 is pivotally provided with an upper cover 4, the top of the outer cylinder 2 is pivotally provided with an outer cylinder cover 5, the outer cylinder 2 is further provided with an outer cylinder lock 21, and the outer cylinder lock 21 can keep the outer cylinder cover 5 in a closed state. Further, the linkage uncovering system mainly comprises a pull rope 8, a first end of the pull rope 8 is connected with an outer cylinder lock 21, a second end of the pull rope 8 is operatively connected with the upper cover 4, and the upper cover 4 can drive the second end of the pull rope 8 when being opened, so that the second end of the pull rope 8 pulls the first end of the pull rope 8 to unlock the outer cylinder lock 21, and the outer cylinder cover 5 is automatically opened under the action of a driving device.
In a preferred embodiment of the present invention, the self-driving means of the outer cylinder cover 5 is a torsion spring provided between the outer cylinder cover 5 and the outer cylinder 2. When the outer cylinder lock 21 is unlocked by the pull rope 8, the outer cylinder cover 5 in the closed state can be automatically opened by the torsion spring. Besides, the skilled person can set the self-driving device of the outer cylinder cover 5 as any feasible device or structure according to the needs, for example, a motor, which connects the output shaft of the motor with the pivoting end of the outer cylinder cover 5, fixedly connects the body of the motor with the outer cylinder 2, and opens the outer cylinder cover 5 when the motor is powered on.
With continued reference to fig. 1, upper cover 4 includes a first free end 41, a pivot end 42, and a second free end 43. The upper cover 4 is pivotally connected to the case 1 through a pivot end 42, and specifically, the pivot end 42 is configured as a semicircular structure (not shown), and the semicircular structure is pivotally connected to the case 1 through a rotating shaft (not shown). Or the pivoting end 42 can be provided in any other feasible configuration, such as a plate-like configuration parallel to the first free end 41 and/or the second free end 43, as desired by those skilled in the art. The first free end 41 and the second free end 43 are located on either side of the pivot end 42. Wherein the first free end 41 corresponds to the laundry input opening of the cabinet 1, and the first free end 41 covers the laundry input opening when the upper cover 4 is closed.
As shown in fig. 1 and 2, the linked cover opening system for a top-loading drum washing machine of the present invention further includes a cylinder 6, an elastic restoring device 7, and a pulling rope 8. The cylinder 6 mainly includes a piston rod 61 and a cylinder 62. The end of the piston rod 61 remote from the cylinder 62 is pivotally connected to the second free end 43 and the end of the cylinder 62 remote from the piston rod 61 is pivotally connected to the tank 1. During the opening of the lid 4, the second free end 43 exerts a longitudinal force on the cylinder 6, under which the piston rod 61 moves towards the cylinder 62, providing damping to the lid 4, preventing the lid 4 from opening too quickly and making a noise in the case of collision with the tank 1. Furthermore, the skilled person can replace the cylinder 6 by any other possible damper, such as a rotary damper, for damping the opening of the cover 4, as desired.
With continued reference to fig. 1 and 2, the second end of the pulling rope 8 is connected to the elastic resetting device 7, and the upper cover 4 can abut against the elastic resetting device 7 in the opening process, and drives the elastic resetting device 7 to drive the second end of the pulling rope 8 to pull the first end of the pulling rope 8 to unlock the outer cylinder lock 21.
As shown in fig. 2, the elastic return means 7 mainly comprises a movable member 71, a spring 72 and a fixed member 73. Wherein, the fixed part 73 is fixedly connected with the box body 1 or integrally formed, the movable part 71 is slidably arranged in the fixed part 73 along the self axis direction, and the spring 72 is arranged between the movable part 71 and the fixed part 73. Specifically, stationary member 73 has an interior cavity (not shown) and moveable member 71 has a shoulder (not shown). In a normal state, the upper end of the shoulder of the movable element 71 abuts against the upper wall of the inner cavity of the fixed element 73, the lower end of the shoulder of the movable element 71 abuts against the upper end of the spring 72, and the lower end of the spring 72 abuts against the lower wall of the inner cavity of the fixed element 73. The spring 72 is normally in a compressed state, for keeping the shoulder of the mobile element 71 always against the upper wall of the internal cavity of the fixed element 73.
With continued reference to fig. 2, the upper end of the movable member 71 is connected to the second end of the pull cord 8, and the upper end of the movable member 71 is spaced from the second free end 43 when the lid 4 is closed. Only after the upper cover 4 is opened by a predetermined angle, the end (right end in fig. 2) of the second free end 43 abuts against the upper end of the movable piece 71. At this time, with further opening of the upper cover 4, the end of the second free end 43 drives the movable piece 71 to move downward along the axial direction thereof. The movable member 71 can pull the pulling rope 8 to unlock the outer cylinder lock 21 during the downward movement.
Further, as can be seen from fig. 2, during the process that the second free end 43 drives the movable piece 71 to move downward along the axial direction thereof, the end of the second free end 43 is in sliding contact with the upper end of the movable piece 71. In order to avoid abrasion of the end of the second free end 43 and the upper end of the movable member 71 and to make the opening operation of the upper cover 4 smoother, the end of the second free end 43 is further provided with a roller 44, so that the second free end 43 is in rolling contact with the upper end of the movable member 71 through the roller 44.
As shown in fig. 1, the case 1 is provided with a plurality of pulleys 11, a first end of the pull rope 8 is connected to the outer cylinder lock 21, a second end of the pull rope 8 is connected to an upper end of the movable member 71, and a portion between the first end and the second end of the pull rope 8 sequentially passes around the plurality of pulleys 11 so as to place the pull rope 8 in a stretched state.
The opening of the cover of the top-loading drum washing machine according to the present invention will be described with reference to fig. 1 and 2.
First, the user manually opens the upper cover 4. When the upper cover 4 is rotated to a predetermined angle (shown by a dotted line in fig. 2), the roller 44 of the upper cover 4 abuts against the upper end of the movable member 71. With further opening of the upper cover 4, the movable piece 71 is driven by the upper cover 4 to move downward against the elastic force of the spring 7. During the downward movement of the movable member 71, the movable member 71 pulls the pull rope 8, so that the pull rope 8 unlocks the outer cylinder lock 21. After the outer cylinder lock 21 is unlocked, the lock catch on the outer cylinder cover 5 is disengaged from the outer cylinder lock 21, and the outer cylinder cover 5 is automatically opened under the action of the torsion spring.
When the upper cover 4 and the outer cylinder cover 5 need to be closed, the user first closes the upper cover 4 by a certain angle, so that the roller 44 is separated from the contact with the movable member 71, the movable member 71 is restored to the original position under the action of the spring 72, and the outer cylinder lock 21 is restored to the original state under the action of the elastic device (such as a spring). At this time, the user manually closes the outer cylinder cover 5 again, and causes the outer cylinder lock 21 to lock the outer cylinder cover 5 in the closed state. Or a person skilled in the art can also arrange a corresponding linkage cover closing mechanism between the upper cover 4 and the outer cylinder cover 5 as required, so that the user only needs to perform the operation of closing the upper cover 4 to simultaneously close the upper cover 4 and the outer cylinder cover 5. The lid closing mechanism may be any feasible mechanism, such as a rod-like structure disposed inside the upper lid 4, one end of the rod-like structure being fixedly connected to the inside of the upper lid 4, and the other end of the rod-like structure being contactable with the outside of the outer cylinder lid 5.
It should be noted that the preset angle at which the upper cover 4 is opened can be set according to actual needs. Preferably, the preset angle is greater than zero so that the outer tub cover 5 can be opened only after the upper cover 4 is opened by a certain angle, preventing a user from applying a great force when the upper cover 4 and the outer tub cover 5 are simultaneously opened. Further, the person skilled in the art may also set the upper cover 4 and the outer cylinder cover 5 to be able to be opened simultaneously as needed.
In conclusion, the linkage uncovering system can enable the outer drum cover 5 to be automatically opened when the upper cover 4 is opened, simplifies the operation steps of opening the upper cover 4 and the outer drum cover 5 of the top-opening type drum washing machine by a user, and optimizes the use experience of the user.
In addition, as an alternative embodiment of the present invention, the elastic return means 7 and the roller 44 may be omitted, and the second end of the pull cord 8 may be directly connected to the end of the second free end 43 of the upper cover 4. Also, the arrangement position of the pulley 11 in fig. 2 is appropriately adjusted, for example, the pulley 11 in fig. 2 is arranged above the end of the second free end 43. Although this embodiment is simpler in structure than the above-described preferred embodiment of the present invention, the outer lid 5 is opened simultaneously with the opening of the upper lid 4, which not only makes the user labor-consuming, but also the outer lid 5 may collide with the upper lid 4 and generate noise while the upper lid 4 and the outer lid 5 are opened.
It should be noted that, although the present section describes the linked cover opening system of the present invention by taking a top-loading drum washing machine as an example, the linked cover opening system of the present invention can also be applied to other types of washing machines, such as a pulsator washing machine having an outer drum cover and an upper cover.
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.
