1. A washing apparatus comprising:
a cabinet;
a cylinder assembly arranged inside the cabinet and including an inner cylinder, an outer cylinder, and a window gasket, wherein the inner cylinder is rotatably arranged in the outer cylinder and the window gasket is connected with the outer cylinder;
a valve assembly;
an air inflow pipeline communicated with the window gasket;
an air outflow pipeline communicated with the outer cylinder; and
a fan arranged on the air inflow pipeline and/or the air outflow pipeline;
wherein the valve assembly comprises a blocking mechanism, and a valve casing having an air inflow cavity and an air outflow cavity formed within the valve casing;
wherein the air inflow cavity and the air outflow cavity are arranged independently from each other;
wherein the blocking mechanism comprises a driving motor, a first blocking member and a second blocking member;
wherein an output shaft of the driving motor is connected to the first blocking member and the second blocking member simultaneously;
wherein the first blocking member is arranged in the air inflow cavity, the second blocking member is arranged in the air outflow cavity, and the driving motor is configured to drive the first blocking member and the second blocking member to move simultaneously to block the air inflow cavity and the air outflow cavity;
wherein the driving motor is connected to a transmission shaft, the first blocking member is a first blocking plate, and the second blocking member is a second blocking plate;
wherein both the first blocking plate and the second blocking plate are arranged on the transmission shaft;
wherein the air inflow pipeline is arranged to communicate an outside of the washing apparatus with the cylinder assembly and to be communicated with the air inflow cavity, and the air outflow pipeline is arranged to communicate the outside of the washing apparatus with the cylinder assembly and to be communicated with the air outflow cavity; and
wherein the driving motor is configured to drive the transmission shaft to rotate so that the first blocking plate and the second blocking plate rotate simultaneously to block the air inflow pipeline and the air outflow pipeline simultaneously.
