Abstract
Description
Technical fields:
[0001] This utility model relates to an emergency unlocking device for a drum washing machine and a drum washing machine, which belongs to the field of washing machine technology. Background technology:
[0002] With the rapid development of the washing machine industry, especially multi-drum washing machines, emergency pull rings are widely used as an emergency unlocking device for washing machines. Generally, emergency pull rings are installed in the emergency drain box at the bottom of the washing machine or on the back cover of the washing machine. When a problem occurs and an emergency unlock is needed, the user needs to squat down or move the washing machine to the back to unlock it, which is inconvenient for the user.
[0003] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility model content:
[0004] This utility model provides an emergency unlocking device and a drum washing machine to solve the problems existing in the prior art. The device has an emergency pull ring installed on the upper bracket for easy user operation.
[0005] This utility model adopts the following technical solution: an emergency unlocking device for a drum washing machine. The drum washing machine includes a washing machine frame structure, which includes an upper bracket, a front middle crossbeam located below the upper bracket, and a door lock reinforcing plate connected between the upper bracket and the front middle crossbeam and perpendicular to the upper bracket and the front middle crossbeam. A door lock pull ring is installed on the upper bracket, and a door lock assembly is installed on the inner side of the door lock reinforcing plate. The door lock assembly includes a micro switch. A first opening is provided on the door lock reinforcing plate below the door lock assembly, and a second opening is provided on the upper bracket above the door lock reinforcing plate. One end of the micro switch is connected to a thin rope, and the other end of the thin rope passes through the first opening and the second opening in sequence and is wrapped around one end of the door lock pull ring.
[0006] Furthermore, guide wheels are installed at both the upper and lower ends of the door lock reinforcing plate. The other end of the thin rope passes through the first opening, then through the guide wheel at the lower end and the guide wheel at the upper end, then through the second opening, and finally wraps around one end of the door lock pull ring.
[0007] Furthermore, a recessed platform is formed on the upper bracket behind the second opening. The end of the door lock pull ring with a thin rope wrapped around it is supported on the recessed platform, and the end of the door lock pull ring without the thin rope wrapped around it is installed on the upper bracket by screws.
[0008] Furthermore, a control panel is mounted on the upper bracket.
[0009] Furthermore, the door lock ring is hidden behind the control panel.
[0010] Furthermore, the number of door lock pull rings is consistent with the number of drums in the drum washing machine.
[0011] The present invention also adopts the following technical solution: a drum washing machine, including the emergency unlocking device of the drum washing machine described in any one of the preceding claims.
[0012] This utility model has the following beneficial effects:
[0013] (1) The door lock pull ring is set on the upper bracket and hidden through the control panel, so as not to affect the appearance.
[0014] (2) The door lock pull ring is about 1.3m above the ground, which is a suitable height and convenient for users to operate.
[0015] (3) The door lock reinforcing plate is equipped with two guide wheels spaced apart vertically for threading thin ropes. The guide wheels guide the thin ropes to facilitate long-distance unlocking of the door lock pull ring. Attached image description:

[0019] Figure 4 for Figure 2 Top view. Detailed implementation method:
[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] This utility model discloses an emergency unlocking device for a drum washing machine. The drum washing machine includes a washing machine frame structure, which includes an upper support 1, a front middle crossbeam 2 located below the upper support 1, and a door lock reinforcing plate 3 connected between the upper support 1 and the front middle crossbeam 2 and perpendicular to the upper support 1 and the front middle crossbeam 2. A door lock assembly 4 is installed on the inner side of the door lock reinforcing plate 3. The door lock assembly 4 includes a micro switch (not shown). A first opening 30 is provided on the door lock reinforcing plate 3 below the door lock assembly 4, and a second opening 31 is provided on the upper support 1 above the door lock reinforcing plate 3. Guide wheels 32 are installed at both the upper and lower ends of the door lock reinforcing plate 3 by screws. A thin rope 5 is connected to one end of the micro switch. The other end of the thin rope 5 passes through the first opening 30, then passes through the guide wheel 32 at the lower end and the guide wheel 32 at the upper end, then passes through the second opening 31, and finally wraps around one end of the door lock pull ring 6.
[0022] A recessed platform 10 is formed on the upper bracket 1 behind the second opening 31. The end of the door lock pull ring 6 with a thin rope 5 wrapped around it is supported on the recessed platform 10. The end of the door lock pull ring 6 without the thin rope 5 wrapped around it is installed on the upper bracket 1 by screws. A control panel (not shown) is installed on the upper bracket 1. The door lock pull ring 6 is hidden behind the control panel and does not affect the appearance of the washing machine.
[0023] When a user needs to unlock the door, first remove the screw on the door lock ring 6 where the end of the thin rope 5 is not attached. Then, pull the door lock ring 6 by hand. As the door lock ring 6 is pulled upward, the thin rope 5 moves along the guide wheel 32 at both the upper and lower ends, thereby actuating the micro switch and unlocking the door. How the micro switch achieves unlocking is common knowledge in the field and will not be elaborated upon in this patent application.
[0024] When the washing machine is a single-drum washing machine, a door lock pull ring as described above can be installed to unlock it. When the washing machine is a multi-drum washing machine, multiple door lock pull rings as described above can be installed according to the number of drums to unlock them individually.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
