Problems solved by technology

However, the rotation speed of the drum greatly affects the dehydration performance
In addition, dehydration performance greatly affects rinsing performance and drying performance
That is, if the dehydration rate is poor, the detergent components cannot be sufficiently removed during rinsing, and the rinsing performance will decrease.
In addition, if the dehydration rate is poor, the laundry cannot be dried quickly when the laundry is spin-dried or dried.
Therefore, easily reducing the spin speed will lead to a decrease in spin performance, which in turn leads to a decrease in rinsing performance and drying performance

no. 1 approach

[0025] First, refer to Figure 1 to Figure 9 The first embodiment will be described.

[0026] figure 1 The washing machine 10 illustrated in FIG. 2 is a so-called vertical axis type washing machine in which the rotation axis of the drum is oriented in the vertical direction. The washing machine 10 includes an outer case 11 , a top cover 12 , a water tub 13 , an elastic support mechanism 14 , a drum 15 , a drive mechanism 16 , a water supply mechanism 17 , and a drain mechanism 18 . Outer case 11 is formed into a rectangular hollow box shape from, for example, a stainless steel plate or the like to constitute the outer contour of washing machine 10 .

[0027] The top cover 12 is arranged on the upper part of the outer box 11 . The top cover 12 has a laundry inlet and outlet 121 and a cover 122 . Lid 122 is provided so as to be able to open and close laundry inlet and outlet 121 . The user puts laundry into drum 15 or takes laundry out of drum 15 through laundry inlet and o...

no. 2 approach

[0079] Next, also refer to Figure 10 A second embodiment will be described.

[0080] The washing machine 10 of the second embodiment differs from the first embodiment in the details of the correction processing executed by the correction processing unit 32 . That is, in the second embodiment, by figure 2 The correction processing performed by the shown correction processing section 32 is processing based on the figure 1 and figure 2 The temperature measured by the temperature sensor 23 shown in , corrects the unbalanced load amount estimated from the vibration detected by the vibration sensor 22 in the first estimation processing unit 33 and the second estimation processing unit 34 .

[0081] That is, the correction process of the second embodiment is a process of correcting the unbalanced load amount estimated from the amount of vibration detected by the vibration sensor 22 to match the ambient temperature around the washing machine 10 detected by the temperature sensor...

Abstract

The invention aims to guarantee the dehydrating performance during the dehydration process and inhibit the vibration. A washing machine comprises an outer box, a water drum; a roller; a vibration sensor, which is used to detect the vibration of the water drum; a first judging and processing part, which judges the imbalance loads of the water drum based on the vibration detected by the vibration sensor during a first period from the start of acceleration to the time when the rotation speed becomes stable; a second judging and processing part, which judges the imbalance loads of the water drum based on the vibration detected by the vibration sensor during a second period from the first period to the time when the rotation speed becomes stable; a load difference calculating and processing part, which calculates the imbalance load between the imbalance loads judged by the first judging and processing part and the imbalance loads judged by the second judging and processing part; and a rotation speed adjusting and processing part, which adjusts the rotation speed of the roller after the second period based on the imbalance load calculated by the load difference calculating and processingpart.

Description

technical field [0001] The invention relates to a washing machine. Background technique [0002] In recent years, the increase in capacity of washing machines has progressed, and the amount of laundry to be washed in one operation has increased. In addition, since clothes are made of various materials, clothes with various water absorption rates are mixed together, and therefore, the amount of moisture change in the laundry during dehydration also increases compared with conventional ones. As a result, in recent washing machines, a so-called imbalance in which the weight of the laundry in the drum is skewed during spin-drying tends to occur. Moreover, if an imbalance occurs during dehydration, the vibration during dehydration increases, and this vibration becomes noise, resulting in a decrease in quietness. [0003] On the other hand, for example, since users have various lifestyles, there is also a need to operate at a time that suits one's preference, such as at night, w...
