Problems solved by technology

However, special nozzles cause cost increases, and pump pressure needs to be increased, which also causes cost increases.
In addition, the technologies disclosed in Patent Documents 1, 3, and 4 are such that the piping of the water circulation system penetrates through the front end wall of the water tank and faces the inside of the rotating drum, and the piping structure becomes more complicated, which further increases the cost.

Abstract

The invention provides a drum type washing machine having a rotary drum installed in a water tank and capable of executing at least one of washing process and rinsing process by driving the rotary drum by a motor, including a water circulation mechanism for circulating the water in the water tank by a circulation pump through a circulation route connected to the water tank, in which the water circulation mechanism has a passage for discharging the circulation water in the rotary drum provided between the wall reverse side of the water tank and the wall surface of the rotary drum, and the circulation water is discharged into the rotary drum from the annular outlet formed between the inner circumferences of the front end walls.

Description

technical field [0001] The present invention relates to a drum type washing machine which has a bottomed cylindrical rotating drum in a water tank, and washes laundry accommodated in the rotating drum by rotating and driving the rotating drum. Background technique [0002] As such a drum-type washing machine, a washing machine having a circulation function of circulating water in a water tank by a circulation pump is known. [0003] For example, in JP-A-11-276791 (Patent Document 1), one pump is utilized in two cases. First, the pump is used as a circulating pump in the washing process and rinsing process to circulate the rinsing water and washing water, so that the detergent and washing water are fully stirred and the detergent is dissolved in advance in the early stage of the washing process. Second, use the pump as a drain pump in the dehydration and drainage process. A filter box is provided in the middle of the water inlet side of the circulation pump in the circulati...
