Problems solved by technology

[0008] However, since the amount of water supplied to the drum type washing machine is small, it takes time to dissolve the detergent and supply the washing liquid evenly to the laundry, resulting in uneven washing, reduced cleaning power, and prolonged washing time.

Embodiment 1

[0023] figure 1 It is a block circuit diagram of a drum type washing machine in an embodiment of the present invention. figure 2 It is a cross-sectional view of the front-loading washing machine according to Embodiment 1 of the present invention. figure 2 The left side of the screen indicates the front of the washing machine, and the right side indicates the rear side of the washing machine.

[0024] exist figure 1 and figure 2 Among them, the control device 21 has a control mechanism 22 composed of a microcomputer, and controls the actions of the motor 5, the drain pump 10, the water supply valve (water supply mechanism) 11, etc. by means of the power switching mechanism 15. As a result, a series of steps such as washing, rinsing, and dehydration are sequentially controlled. During the washing process, the washing liquid foam generated by the control mechanism 22 is added to the laundry in the rotary drum 1 for washing.

[0025] Next, the operation of the washing pr...

Embodiment 2

[0033] Image 6 It is a sectional view of the front-loading-type washing machine in Example 2 of the present invention. Image 6 The left side of the screen is the front of the washing machine, and the right side is the rear side of the washing machine.

[0034] as in Image 6 As shown above, in the drum type washing machine of Embodiment 2, the central axis of rotation of the rotating shaft 4 of the rotating drum 1 is inclined, and the front of the rotating drum is higher than the rear. The other structures are the same as in Embodiment 1, and are assigned the same symbols, and descriptions thereof are omitted.

[0035] During the washing process, the detergent foam generated by the control mechanism 22 of the control device 21 soaks into the laundry in the rotary drum 1 to perform washing. At this time, the detergent foam flows from the position where the central axis of rotation is high (in front of the rotating drum) to the oblique rear.

[0036] Next, the washing oper...

Embodiment 3

[0042] In this embodiment, when the control mechanism 22 generates detergent foam and provides detergent foam during the washing process, the rotary drum 1 is rotated. Other structures are the same as the above-mentioned embodiment 1.

[0043] The operation of the washing process in the above construction will now be described. Detergent foam was generated in the same manner as in Example 1. The detergent foam produced by the continuous rotation of the rotary drum 1 rises from between the rotary drum 1 and the water receiving tank 3 under the action of centrifugal force, and overflows from the front upper part of the washing machine. At this time, the detergent foam is supplied while rotating the rotary drum 1, and the detergent foam generally soaks the laundry in the rotary drum 1, and then returns to between the rotary drum 1 and the water receiving tank 3 through the laundry. This allows the detergent suds to circulate.

[0044] As described above, by supplying detergent...

Abstract

A drum type washing machine includes rotating drum having a rotating axis in a substantially horizontal direction and sustained rotatably in a tub. The washing machine further includes a motor for driving the rotating drum, a water supplying means for supplying water into the tub, and a controlling means for washing, rinsing and liquid-extracting by controlling workings of the motor. The controlling means of the washing machine washes a laundry by pouring detergent bubbles in the washing process.

Description

technical field [0001] The invention relates to a drum type washing machine which controls washing, rinsing, dehydration and other processes to wash laundry in a rotating drum. Background technique [0002] exist Figure 8 Shown above is a cross-sectional view of an existing drum-type washing machine, Figure 9 Shown is a block diagram. as in Figure 8 and Figure 9 As shown in , the rotating drum 1 has a plurality of water passage holes 2 on the entire outer peripheral surface, which can be freely rotatably installed in the water receiving tank 3 . And the rotation shaft 4 is installed in the substantially horizontal direction of the rotation center axis of the rotary drum 1 . The motor 5 is connected with the rotating shaft 4 to drive the rotating drum 1 to rotate. A plurality of protruding plates 6 are provided on the inner wall of the rotary drum 1 . [0003] The sink 3 is hung on the washing machine body 7 by a spring 8 and can be shaken. One end of the drain pipe...
