Description
Technical field
The present invention relates to roller washing machine, particularly a kind of antibiotic plastic reaches the erecting bed of the roller washing machine of being made by its.
Background technology
In general, roller washing machine is to utilize drum cylinder rotation and the drop that produces washs the washing machine of washes in the mode of washing by rubbing with the hands, has washes seldom to occur because of the impaired advantage of winding mutually.In addition, such roller washing machine according to the program of input wash automatically, rinsing and dehydration supervisor.
Such roller washing machine, for taking out or put into a front of washes at body, the position of door is lower comparatively speaking, so when taking out or put into washes, upper body is crooked largely, the user feels inconvenience, therefore utilizes erecting bed to install for the installation site of improving roller washing machine.
In addition, when roller washing machine was installed on the ground of surface irregularity, use had the erecting bed of adjusting horizontal device and installs.
