Exemplarily, the drum assembly comprises an outer drum and an inner drum rotatably arranged in the outer drum, and the space in the inner drum is the clothes treatment cavity. In some embodiments, the laundry treating apparatus may be provided with only the inner tub, without the outer tub.

It will be appreciated that the inner barrel described above may be a perforated inner barrel or a non-perforated inner barrel. When the inner cylinder is a porous inner cylinder, water is contained by the outer cylinder; when the inner barrel is a non-hole inner barrel, the inner barrel is used for containing water, namely, the inner barrel can contain water and clothes, and the water in the inner barrel cannot enter the outer barrel in the washing process. When the barrel component only has an inner barrel and does not have an outer barrel, the inner barrel is a non-hole type inner barrel.

The door body 1 is rotatably connected with the case 2 to selectively close or open the clothes input opening 2a, the door body 1 is provided with a door hook 11, the door lock mechanism 3 is arranged on the case 2, and the door lock mechanism 3 is matched with the door hook 11. The first magnetic attraction component 4 and/or the second magnetic attraction component 5 can reciprocate along the extending direction of the door hook 11, that is, the first magnetic attraction component 4 and/or the second magnetic attraction component can move relatively. The laundry treating apparatus includes a fully-off state, a primary on state, and a secondary on state.

A fully closed state: the door lock mechanism 3 locks the door hook 11, the first magnetic component 4 and the second magnetic component 5 are attracted, and the door body 1 seals the clothes throwing opening 2 a. In this state, the laundry treating apparatus can perform washing processes of water supply, water discharge, laundry washing, etc.

In a first-stage opening state, the door lock mechanism 3 releases the door hook 11 and opens the door body 1 to form a gap between the door body 1 and the clothes feeding opening 2a, the first magnetic suction component 4 and the second magnetic suction component 5 are kept sucked, the gap provides a ventilation channel for the inside of the case 2, and the clothes are prevented from mildewing and smelling in the clothes treatment cavity. It can be understood that, in the primary state, the laundry treating apparatus may also turn on the drying function to dry the laundry.

And in a second-stage opening state, the first door lock mechanism 3 releases the door hook 11, and the first magnetic component 4 and the second magnetic component 5 are separated. In this state, the door body 1 is in a free state.

The clothes treatment equipment of this application embodiment inhales subassembly 4 and the cooperation of subassembly 5 is inhaled to the second through door hook 11, lock mechanism 3, first magnetism, realizes the effect that clothes treatment equipment multistage opened the door. Specifically, when the washing is finished, the door latch mechanism 3 releases the door hook 11 and opens the door body 1, and the laundry treating apparatus enters a first-stage open state. Because the first magnetic component 4 and the second magnetic component 5 are still in the attraction state, in the opening process of the door body 1, the first magnetic component 4 moves towards the direction close to the case 2 under the action of attraction force, and/or the second magnetic component 5 moves towards the direction of the door body 1 under the action of attraction force to compensate the opening range of the door body 1. The opening range of the door body 1 is determined by the movement stroke of the first magnetic attraction component 4 and/or the second magnetic attraction component 5. When the clothes drying machine enters a secondary opening state, the door body 1 is in a free state, and a user can take out the clothes from the clothes treatment cavity to dry the clothes.

It should be noted that the specific structure of the door lock mechanism 3 may be the structure existing in the prior art, and is not described herein again.

It should be noted that, in some embodiments, only the first magnetic attraction assembly 4 moves along the extending direction of the door hook 11, and the second magnetic attraction assembly 5 does not move, in this embodiment, the opening range of the door body 1 in the first-stage opening state is determined by the movement stroke of the first magnetic attraction assembly 4. In other embodiments, only the second magnetic attraction assembly 5 moves along the extending direction of the door hook 11, and the first magnetic attraction assembly 4 does not move, in this embodiment, the opening range of the door body 1 in the first-stage opening state is determined by the movement stroke of the second magnetic attraction assembly 5. In still other embodiments, the first magnetic attraction assembly 4 and the second magnetic attraction assembly 5 are both capable of moving along the extending direction of the door hook 11, in this embodiment, the opening range of the door body 1 in the one-stage opening state is determined by the movement stroke of the first magnetic attraction assembly 4 and the movement stroke of the second magnetic attraction assembly 5.

For example, in the embodiment of the present application, the first magnetic attraction component 4 is described as moving along the extending direction of the door hook 11.

The specific type of the first magnetic attraction member 4 and the second magnetic attraction member 5 is not limited as long as the attraction force can be generated therebetween. For example, in one embodiment, one of the first magnetic attracting assembly 4 and the second magnetic attracting assembly 5 is a permanent magnet, and the other is a permanent magnet or a ferromagnetic member. In another embodiment, one of the first magnetic attraction component 4 and the second magnetic attraction component 5 is an electromagnet, and the other is a permanent magnet or a ferromagnetic member.
