Embodiment approach 1

[0034] figure 1 It is a longitudinal sectional view of the front-loading-type washing machine in Embodiment 1 of this invention.

[0035] like figure 1 As shown, the front-loading washing machine of this embodiment includes at least a water tank 52 disposed in the washing machine main body 51 to be able to swing freely; a bottomed cylindrical rotating drum 53 disposed in the water tank 52 to be freely rotatable; and The motor 54 is installed on the outer side of the back surface of the water tank 52 , and the rotary drum 53 is rotationally driven by the motor 54 . At this time, for example, a concave drainage ditch 76 having a drainage port 71 is provided at the inner lower part of the side wall of the water tank 52 along the direction of the rotating shaft 63 of the rotary drum 53 .

[0036] In addition, the front-loading-type washing machine of this embodiment has a function of using the control unit to figure 1 The motor 54 shown, the water supply system 55, the drain...

Embodiment approach 2

[0083] Next, a front-loading washing machine according to Embodiment 2 of the present invention will be described using drawings.

[0084] Figure 5A and Figure 5B It is a flowchart explaining the control from the washing process to the spin-drying process in the mode of high-quality finishing process of the front-loading-type washing machine according to Embodiment 2 of the present invention.

[0085] The difference between the front-loading washing machine of this embodiment and Embodiment 1 is that, in the high-quality finishing process mode from the washing process to the dehydration process, a dehydration process is provided after the water discharge in step S8 (step S101). Other controls, operations, and the like are the same as those in Embodiment 1, so explanations are sometimes omitted. Therefore, the dehydration process (step S101) is demonstrated in detail below, and since other processes are the same as Embodiment 1, it demonstrates briefly.

[0086] That is, i...

Abstract

A drum-type washing machine of the present invention includes a water tank supported in a main cabinet of a washing machine, a rotary drum housed in the water tank, a motor rotating the rotary drum, a supply valve supplying water to the water tank, an automated detergent dispenser for automatically feeding detergent to the water tank, an operation display unit including an input setting unit and a display, a drain outlet provided in an inner bottom part of the water tank, a drain valve connected to the drain outlet, a clothes quantity detector for detecting a quantity of clothes , and a controller for controlling a series of cycles including wash, rinse, and spin-dry cycles. The controller includes following modes for feeding the detergent by the automated detergent dispenser based on a result of the clothes quantity detector, supplying water using the supply valve, driving the motor to execute a prewash cycle, then draining the water inside the water tank by operating the drain valve, feeding the detergent of an amount less than that in the prewash cycle by the automated detergent dispenser, supplying water using the supply valve, and then executing a main wash cycle.

Description

technical field [0001] The present invention relates to a drum type washing machine which improves cleaning performance and prevents clothes from getting dark. Background technique [0002] In conventional washing machines, in order to improve cleaning performance, for example, in Japanese Patent Application Laid-Open No. 2000-342887 (hereinafter referred to as "Patent Document 1"), the following control method is proposed: the washing liquid is set to a high-concentration state. Carry out the cleaning process. [0003] Next, the operation of the conventional washing machine described in Patent Document 1 will be described with reference to the drawings. [0004] Image 6 It is an operation flowchart of the conventional washing machine. Figure 7 It is a front view showing the water volume setting key of the washing machine. Figure 8A and Figure 8B It is a figure which shows an example of the indicator lamp which shows the amount of detergent of this washing machine. ...
