Clothes treatment equipment and defoaming method thereof

The invention discloses clothes treatment equipment and a defoaming method thereof. The clothes treatment equipment comprises an inner cylinder and an outer cylinder, and an atomizing nozzle capable of eliminating foam between the inner cylinder and the outer cylinder is arranged on the outer cylinder. The defoaming method comprises the steps that in the washing process, the foam detection device is used for detecting the foam amount in the water inlet box; and when the amount of foam in the water inlet box is larger than or equal to the preset amount, foam between the inner barrel and the outer barrel is eliminated through the atomization nozzle. Foam between the inner drum and the outer drum is atomized, sprayed and defoamed through the atomizing nozzle on the outer drum, and if it is judged that the foam in the drum of the washing machine is too much, the atomizing nozzle continuously starts defoaming, so that the foam between the inner drum and the outer drum can be quickly eliminated, air in the drum can
