The invention discloses a window frame preventing dust from entering a slide groove. The window frame preventing dust from entering the slide groove comprises a window frame body and a window. The slide groove is formed in the bottom of the window frame body, and two zipper tapes are arranged at the two sides of the slide groove correspondingly and matched with each other. Two zipper heads in a reversed direction are arranged at the zipper tapes, the window is arranged between the two zipper tapes, and fixed structures used for fixing the zipper heads are arranged at the two sides of the window. Grooves holding zipper teeth of the zipper tapes are formed in the two sides of the window, guide grooves are formed in the upper and lower sides of the zipper teeth, and guide raised lines matched with the guide grooves are arranged at the two sides of the grooves downwards. By adoption of the structure in the process of moving the window, the zipper head at the front of the forward direction of the window separates the two zipper tapes and the zipper head at the back of the forward direction of the window locks the two zipper tapes, thereby making the slide groove sealed by the zipper tapes all the time, preventing the dust from entering zippers, and preventing dust and impurities from affecting the sliding of the window.

The invention belongs to the technical field of washing.
