Embodiment 1

[0033] figure 1 is a perspective view of the drum type washing machine 100 of the present invention, figure 2 It is a side view showing the internal structure of the front-loading washing machine 100 . use figure 1 and figure 2 , the structure and operation of the front-loading washing machine 100 will be described.

[0034] constitute figure 1 The shell 1 of the outline of the drum type washing machine 100 shown is installed on the base 1a, and the left and right side plates 1b ( figure 1 Only the right side panel is shown in the figure), front cover 1c, rear cover 1d (refer to figure 2 ), top cover 1e, and lower front cover 1f constitute. The upper cover 1e is provided with a water supply hose connection port 30 for supplying water from a water tap to the front-loading washing machine 100 . The casing 1 includes a box-shaped outer frame with a base 1a, and has sufficient strength as an outer frame.

[0035] The door 2 is a member for closing an inlet (not shown) p...

Embodiment 2

[0069] Then refer to Figure 6 Example 2 will be described in detail.

[0070] In addition, since front-loading-type washing machine 100 has basically the same structure as that of Embodiment 1, different parts will be described below.

[0071] Fig. 7 shows a flow chart of the dehydration step of the second embodiment. In addition, the spin-drying operation after the first unbalance determination ( 209 ) and before the rotation up of the drum 21 ( 210 ) is the same as that of the first embodiment, and the same reference numerals are used to omit description.

[0072] In Embodiment 2, when the imbalance in the high-speed rotation speed region is greater than the threshold value of the vibration sensor 18 in the third imbalance judgment (211), the rotation speed of the drum 21 is temporarily stopped (300), and the attachment state setting according to the first dehydration is cleared. fixed ω 2 settings (301). Afterwards, disengage action (302), the rotation of drum 21 is te...

Abstract

By attaching the laundry to the unbalanced side in the low-speed rotation region of the spin-drying process, it is possible to shorten the correction time of the imbalance when large-sized clothes such as a carpet and a felt having different combinations are combined, and to provide a drum type washing machine and a drum type washing and drying machine that suppress the increase in the dehydrationtime and the amount of power consumption. The drum type washing machine comprises: a rotatable drum which is horizontally inclined or inclined in a manner that the depth side is downward; an outer tub which encloses the drum and is used for storing washing water; a casing which encloses the outer tub; a judging means and an imbalance determining means which judge the attaching state of the laundry in the rotatable drum ad the imbalance determination of the laundry in the first dehydrating operation. The first dehydrating operation is performed when the imbalance is greater than the thresholdof the imbalance determining means during the determination of the attachment state of the laundry. The rotation control of the dehydration operation after the second dehydration is started again, andthe rotation control of the second and subsequent dehydration operations is different from the dehydration operation.

Description

technical field [0001] The invention relates to a drum type washing machine for washing and dehydration and a drum type washing and drying machine for washing, dehydration and drying. Background technique [0002] In the drum-type washing machine, the housing includes an outer tub for storing water, and the outer tub includes a drum for putting clothes into it to perform various processes of washing, rinsing and dehydration. In the low-speed rotation speed region at the beginning of the dehydration process, the rotation speed of the drum is increased step by step, and the clothes are attached to the drum at the same time, and the unbalance detection mechanism for judging the unbalance of the clothes attached to the drum is used to determine that the unbalance is less than the set value. When the threshold value is reached, the rotation speed of the drum is increased. When it is determined that the imbalance is greater than the threshold value, the rotation of the drum is st...
