Washing device

A washing device, comprising:

• a main machine;
• an inner container assembly which is arranged on the main machine and provided with a washing cavity, the inner container assembly being provided with liquid outlet holes and a backflow opening which communicate with the washing cavity, the bottom wall of the washing cavity inclining relative to the horizontal direction, the backflow opening being located in the side with lower height of the bottom wall of the washing cavity, and the horizontal height of the liquid outlet holes being greater than that of the backflow opening;
• and
• a washing module comprising a water pump and a circulation pipeline, an input end of the water pump communicating with the backflow opening by the circulation pipeline while an output end thereof communicating with the washing cavity through the liquid outlet holes so as to spray cleaning water to a part to be washed in the washing cavity;
• and
• a support assembly and an air supply module, wherein a first air inlet communicating with the washing cavity is formed in the bottom wall of the inner container assembly, and the horizontal height of the first air inlet is greater than that of the backflow opening;
• the support assembly is arranged in the washing cavity and located above the first air inlet;
• the air supply module comprises an air duct shell and a fan assembly;
• the air duct shell is arranged on the outer side of the inner container assembly and is provided with an air supply channel communicating with the washing cavity;
• at least part of the fan assembly is located in the air supply channel;
• and the fan assembly is used for driving outside air to enter the air supply channel and then to enter the washing cavity through the first air inlet;
• and
• a pressurizing portion is formed at the bottom of the inner container assembly and is provided with a second liquid passing cavity;
• a liquid inlet hole is formed in one side of the second liquid passing cavity, and a plurality of liquid outlet holes are formed in the other side of the second liquid passing cavity;
• the diameter of the plurality of liquid outlet holes is smaller than that of the liquid inlet hole;
• and the output end of the water pump, the liquid inlet hole, the second liquid passing cavity, the plurality of liquid outlet holes and the washing cavity sequentially communicate;
• and
• each liquid outlet hole comprises a first liquid outlet hole and a plurality of second liquid outlet holes;
• and the plurality of second liquid outlet holes are arranged at intervals around the central axis of the first liquid outlet hole, and the diameter of the first liquid outlet hole is larger than or equal to that of the second liquid outlet holes.
