Embodiment approach 1

[0017] figure 1 It is a sectional view showing the schematic structure of the front-loading-type washing machine according to Embodiment 1 of the present invention.

[0018] Such as figure 1 As shown, the front-loading washing machine of the present embodiment at least includes: a water tank 3 disposed inside the main body 2 of the washing machine so as to be swingable; motor 6, water supply system 7, drainage system 8, drying system 9 and water circulation system 16, etc. The rotary drum 4 is rotationally driven by a motor 6 . In addition, the front-loading washing machine of this embodiment constitutes a so-called front-loading washing machine, and has a function of performing at least a washing step, a rinsing step, a dehydration step, and a drying step through automatic control according to mode settings and a control program. In this case, the drying system 9 may also be omitted.

[0019] In addition, the water supply system 7 supplies water into the water tank 3 in a...

Abstract

The drum type washing machine of the present invention has: a rotating drum (4), which is formed into a bottomed cylinder; a water tank (3), which is equipped with a rotating drum (4) inside; a water circulation system (16), which passes through a circulating pump ( 20) Make the washing water in the water tank (3) circulate through the circulation path (31) connected with the water tank (3); the motor (6), which drives the rotating drum (4); the load detection part (30), which detects the cycle a load of the pump (20); and a control section (22) that controls at least one of a washing step and a rinsing step. Furthermore, when the load detection unit (30) detects a predetermined load fluctuation of the circulation pump (20) when the motor (6) and the circulation pump (20) are driven, the control unit (22) stops the drive of the motor (6). And stop the function of circulation pump (20). Thereby, it is possible to prevent foam and air from entering into the circulating pump (20), and suppress excessive foaming and noise generation.

Description

technical field [0001] The present invention relates to a drum-type washing machine including a unit for circulating washing water. Background technique [0002] Conventionally, there has been disclosed a drum-type washing machine having a circulation function of circulating wash water in a water tub by a circulation pump in order to improve cleaning performance (for example, refer to Patent Document 1). [0003] That is, the above-mentioned front-loading-type washing machine includes a circulation pump as a driving source for spraying washing water to laundry in the water tank. The circulation pump is arranged in a circulation path through which wash water circulates, and is operated while maintaining a predetermined water level by the water level detector. Thereby, the contact between the to-be-processed object (laundry) and washing water can be increased, and the to-be-processed object can be washed efficiently. [0004] However, when most of the laundry thrown into the...
