Drum-type washing machine

Abstract

A drum-type washing machine, comprising: a water tank (2) that stores washing water; a rotating drum (4) rotatably arranged inside the water tank (2) and having an opening (5) on the front surface side thereof; a motor (9) that drives the rotating drum (4); a circulating water path (20) that circulates, towards the rotating drum (4), washing water that is inside the water tank (2); a pump (21) that sends the washing water that is inside the water tank (2) to the circulating water path (20); a nozzle water path (22) that is connected to the circulating water path (20) and is disposed in a substantially circular shape on the outside of the peripheral edge section (23) of the opening (5) of the rotating drum (4); a plurality of nozzles (26) disposed in the nozzle water path (22) so as to spray the washing water that is supplied by the pump (21), towards the inside of the rotating drum (4); and a control unit (32) that drives the motor (9) and the pump (21), and performs the washing steps. The washing steps include: a first rotation step in which the rotating drum (4) rotates at a speed whereat the washing items inside the rotating drum (4) do not stick to the inner peripheral wall of the rotating drum (4); and a second rotation step in which the rotating drum (4) rotates at a speed whereat the washing items inside the rotating drum (4) stick to the inner peripheral wall of the rotating drum (4). In the second rotation step, the control unit (32) drives the pump (21), and supplies washing water to the washing items stuck to the inner peripheral wall of the rotating drum (4).

Description

technical field [0001] The present invention relates to a drum type washing machine for washing clothes and the like. Background technique [0002] Conventional drum-type washing machines consume less water than vertical washing machines, and part of the laundry in the water tank is not soaked in the washing water. Therefore, the washing water in the water tank is circulated into the rotary tank by a pump and sprayed onto the washing (such as , refer to Patent Document 1). [0003] In the front-loading washing machine of Patent Document 1, washing water is sprayed out from the discharge port, and a plurality of the discharge ports are formed at a slight angle from the front surface side of the rotary tank to the center side of the rotary tank. [0004] However, in the above-mentioned conventional structure, the discharge port is provided above the front surface side of the rotary tank, and the washing water is sprayed downward. Therefore, there is a problem in that even if...
