The invention belongs to the technical field of clothes processing equipment, and specifically provides a drum washing machine, a spray system and a drive shaft assembly thereof. The invention aims to solve the problem that the existing circulation spraying device affects the user's observation of clothes in the drum washing machine through the glass observation window. The drum washing machine of the present invention comprises a box body, an outer cylinder fixedly arranged in the box body, an inner cylinder rotatably arranged in the outer cylinder, and a transmission shaft supporting and driving the inner cylinder to rotate. The spraying system of the present invention includes a plurality of injection holes arranged at the bottom of the inner cylinder, a channel formed on the transmission shaft and communicated with the plurality of injection holes, and a circulation pump communicated with the channel. The water inlet of the circulation pump leads into the outer cylinder for pumping the washing water in the outer cylinder to the channel, so that the washing water is sprayed into the inner cylinder through the plurality of spray holes. Therefore, the drum washing machine of the present invention avoids the situation that the washing water ejected from the spray hole completely covers the front end of the inner cylinder, so that the user can observe the washing condition of the clothes through the glass observation window.
Description
technical field [0001] The invention belongs to the technical field of clothes processing equipment, and specifically provides a drum washing machine, a spray system and a drive shaft assembly thereof. Background technique [0002] The existing drum washing machine originates from Europe, and it mainly includes a casing, an outer cylinder and an inner cylinder from the outside to the inside. A front-loading washing machine works in a similar way to hitting clothes with a hammer. When working, the inner cylinder rotates under the drive of the driving motor. With the rotation of the inner cylinder, the clothes are continuously lifted and dropped in the drum, and then lifted and dropped again, doing repeated motions. Under the joint action of washing powder and water, the clothes are washed clean. [0003] In order to improve the effect of washing and rinsing clothes with water, some drum washing machines are also provided with a circulating spray device. For example, the d...
