A drum washing machine

Abstract

The invention provides a drum washing machine, which comprises a machine body, a door body and an inner cylinder, the inner cylinder is rotatably arranged in the machine body, and the inner cylinder holds water during the washing process; the front part of the inner cylinder is arranged for taking out The opening for putting clothes, the door body can be opened / closed and installed on the front of the machine body and corresponds to the opening of the inner cylinder; the opening end of the inner cylinder is connected to the door body in a relatively rotatable and sealed connection; The water device, the water inlet device includes a first water inlet pipe connected to an external water source, a water collection tank arranged on the door body opposite to the first water inlet pipe, and a second water inlet pipe arranged in the door body to communicate with the water collection tank and the inside of the inner cylinder. The drum washing machine of the present invention realizes the circulation heating of the washing water in the non-porous inner cylinder through the circulation heating pipeline, the washing water in the inner cylinder enters the circulation pipeline through the hollow channel of the central rotating shaft for heating, and the heated washing water is heated by the water inlet The connecting pipe returns to the inside of the inner cylinder, and the water in and out of the circulating heating pipeline does not interfere with the rotation of the inner cylinder.

Description

technical field [0001] The invention relates to the technical field of laundry washing equipment, in particular to a drum washing machine. Background technique [0002] In the prior art, a drum washing machine generally includes an inner cylinder and an outer cylinder that fit each other, the outer cylinder is sealed to hold water, the inner cylinder is used to hold clothes, and the inner cylinder is rotated to beat and wash the clothes; at the same time, the inner cylinder is Set the dehydration hole so that the water in the outer cylinder flows into the inner cylinder through the dehydration hole to soak the clothes in the inner cylinder, the water in the inner cylinder flows out to the outer cylinder through the dehydration hole, and the moisture on the clothes in the inner cylinder is dehydrated when the inner cylinder rotates at high speed The hole is discharged to the outer cylinder to realize the purpose of washing the clothes. [0003] However, since the inner cylin...

Problems solved by technology

[0003] However, since the inner cylinder and the outer cylinder are interfitted with each other, dirt is easy to accumulate between the inner and outer cylinders during the use of the washing machine; at the same time, because the inner and outer cylinders are intertwined, the user cannot clean the outer wall of the inner cylinder and the inner wall of the outer cylinder, which increases the number of bacteria in the washing machine , reducing the washing efficiency of the washing machine and the cleanliness of the clothes after washing

[0004] Simultaneously, in the above-mentioned existing washing machine, because the inner cylinder is equipped with an outer cylinder, the washing process of the washing machine is to beat and wash the clothes through the rotation of the inner cylinder, so that the washing capacity of the washing machine is based on the inner cylinder, so that the internal space utilization rate of the washing machine is Low, unable to expand the washing capacity of the washing machine on the existing basis
