Description

Technical Field

[0001] The utility model relates to the technical field of bathing area partitions, in particular to a sliding and side-opening screen used for bathing area partitions. Background Art

[0002] Generally, the bathroom and toilet are located in the same space. However, due to the mist and water flow generated during the bathing process, the humidity in the space is high, which can easily lead to problems such as mold. The bathing area is usually enclosed to separate the bathing area and the toilet area to achieve dry and wet separation.

[0003] Conventional dry and wet separation uses brickwork or glass to separate the bathing area from the toilet area, and a door is reserved for entry and exit of the bathing area. Most common bathroom doors nowadays are either swing-door or sliding-door types. For swing-door bathroom doors, the door panels are generally connected to the door frame via hinges, allowing the door panels to rotate on the door frame to open and close the door. However, space must be reserved for the door panels to rotate, requiring a large amount of space. For sliding-door bathroom doors, guide rails are provided on the door frame, and sliders are provided on the door panels to slide on the guide rails. The sliding sliders slide on the guide rails to adjust the position of the door panels for opening and closing the door. While sliding-door bathroom doors facilitate maintaining a specific door panel position, their structure requires that the door panels remain completely within the plane of the door frame, inevitably occupying a larger entrance and exit space. Therefore, compared to swing-door bathroom doors, the maximum opening space that can be achieved is smaller under the same entrance and exit conditions, which can easily cause inconvenience.

[0004] The technical problem to be solved by the present invention is: how to solve the problem that the existing partition method for separating bathing areas occupies a large space and is inconvenient to use. Utility Model Content
