If the clothes treatment device is used for a long time, the problems of communication cable aging, cable contact electric sparks and the like can be caused, and when the door hook 3 enters the lock hole 21 to be locked, if the positioning is not accurate, the electric sparks can be caused; all the factors are easy to cause fire to burn the clothes processing device and even cause household fire. Once a fire occurs, the economic losses caused by the fire are even greater. Therefore, the protective shell 1 is made of fireproof materials; preferably, the body 11 and/or the cover 12 of the protective shell 1 are sheet metal parts, so that the sheet metal parts are easy to roll and form and convenient to process, and the flame inside the door lock cylinder 2 is prevented from rapidly jumping out to burn the front flange 5 of the machine body.

The washing machine is provided with the door lock. Normally, the door lock is located at the opposite side of the pivot axis of the door body 4 of the clothes processing device, the door hook 3 is located on the door body 4, and the protective shell 1 and the door lock core 2 are integrally arranged on the front flange 5 of the machine body. The structure of the machine body front flange 5 is similar to that of the first embodiment, the arrangement position of the threaded column 52 is matched with the position of the connecting part 14 of the door lock with the protective shell 1, the door lock core 2 is fixed by fixing the protective shell 1, the door hook 3 and the lock hole 21 are accurately positioned for a long time, and the phenomena of jamming and the like during door opening and closing are prevented.

Similarly, the door lock cylinder 2 is connected with a communication cable, a notch 16 is arranged on one side of the lower part of the protective shell 1, which is far away from the door body 4, and the communication cable passes through the notch 16.

Thus, when a fire is started, the flame usually burns upwards, so that the possibility that the flame is exposed from the lower part and the side surface to ignite other combustible objects is avoided, and the risk of the fire is reduced probably. The communication cable is arranged on one side far away from the door body 4, so that the communication cable can be arranged more simply by utilizing the side wall clearance of the clothes treatment device and can reach the control panel directly.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
