Description

Inner cylinder structure of clothes treatment device and clothes treatment device Technical Field The embodiment of the invention relates to the technical field of household appliances, in particular to an inner cylinder structure of a clothes treatment device and the clothes treatment device. Background A laundry treating apparatus, such as a washing machine, includes a housing, an inner tub provided in the housing, and a drain pump through which water in the inner tub is discharged outside the washing machine, thus resulting in high power consumption. Disclosure of Invention In order to solve the above technical problems or at least partially solve the above technical problems, embodiments of the present invention provide an inner drum structure of a laundry treatment apparatus and a laundry treatment apparatus. In a first aspect, an embodiment of the present invention provides an inner cylinder structure of a clothes treatment device, including an inner cylinder, a water guiding structure and a spindle assembly for driving the inner cylinder to rotate, where the water guiding structure is located in an inner cavity of the inner cylinder, the water guiding structure has a water guiding channel communicated with the inner cavity of the inner cylinder, an outlet of the water guiding channel is communicated with a water outlet shaft, the spindle assembly has a hollow rotating shaft, the water outlet shaft penetrates out of a rear cover of the inner cylinder and is arranged in the rotating shaft, and the spindle assembly can rotate relative to the water outlet shaft, so that water in the inner cavity of the inner cylinder is discharged to the outside of the clothes treatment device sequentially through the water guiding channel and the water outlet shaft. According to the inner cylinder structure of the clothes treatment device provided by the embodiment of the invention, the water guide structure is arranged in the inner cavity of the inner cylinder, the water guide structure is provided with the water guide channel communicated with the inner cavity of the inner cylinder, the outlet of the water guide channel is communicated with the water outlet shaft, namely, the inlet of the water guide channel is communicated with the inner cavity of the inner cylinder, the outlet of the water guide channel is communicated with the water outlet shaft, so that the water outlet shaft penetrates out of the rear cover of the inner cylinder and is arranged in the hollow rotating shaft of the main shaft assembly for driving the inner cylinder to rotate, and the water outlet shaft does not rotate, therefore, when the inner cylinder rotates, water in the inner cavity of the inner cylinder can be discharged to the outside of the clothes treatment device through the water guide channel and the water outlet shaft in sequence under the action of centrifugal force, that is, the inner cylinder structure of the clothes treatment device provided by the embodiment of the invention directly discharges water to the outside of the clothes treatment device through the guide of the water guide structure, external driving force is not needed, and energy consumption is saved. In addition, through making the water outlet shaft wear to establish in hollow pivot, effectively utilized the structure of main shaft subassembly, saved the space to a certain extent. Optionally, the inlet of the water guide channel is arranged near the radial outer edge of the inner cavity of the inner cylinder. When the water is drained, the water is thrown to the radial outer edge of the inner barrel under the action of centrifugal force and rotates along with the water collecting cavity, the inlet of the water guide channel is close to the radial outer edge of the inner barrel, a drainage path is shortened, the rotating water can enter the water guide channel from the inlet rapidly under the action of the centrifugal force, and the drainage efficiency is further improved. Optionally, the inlet of the water guide channel faces the rotation direction of the inner cylinder. When draining or dewatering, the water is thrown to the radial outer edge of the inner cylinder under the action of centrifugal force and rotates along with the inner cylinder, and the inlet of the water guide channel faces to the rotation direction of the inner cylinder, that is, the inlet of the water guide channel is opposite to the rotation direction of the water in the inner cylinder, so that the drainage path is further shortened, and the drainage efficiency is improved. Optionally, the water guide structure comprises a water guide part and a mounting part, wherein the water guide part is provided with the water guide channel, the mounting part is positioned at the outlet of the water guide channel, and the water outlet shaft is connected with the mounting part. The water guide part is stably fixed on the water outlet shaft through the mounting part, so that when the inner barrel rotates relati
