Embodiment Construction

[0060]Hereinafter, one embodiment of the dehydration device will be described with reference to the drawings. In addition, terms indicating directions such as "up", "down", "left" or "right" used in the following description are only for the purpose of clear description, and do not limit the principle of the dehydration device in any way.

[0061] (washing machine)

[0062] figure 1 It is a schematic vertical cross-sectional view of a washing machine with a drying function exemplified as the dehydrating device of the present embodiment. use figure 1 , indicating that the washing machine not only has the function of dehydration but also has the function of washing and drying. In addition, the principle of this embodiment is also applicable to devices that do not have a washing function or a drying function.

[0063] The washing machine 100 has a substantially rectangular box-shaped casing 110 and a treatment tank 200 standing upright in the casing 110 . The treatment tank ...

Abstract

The present invention provides a dewatering device, comprising: a dewatering tank which is vertical for containing clothes; a driving part used for driving the dewatering tank to rotate, in order to reach a target rotating speed; a sensing component used for detecting vibration of the dewatering tank; and a control part used for controlling the driving part based on the vibration of the dewatering tank, wherein, in the process that the driving part speeds up the dewatering tank, when the vibration of the dewatering tank detected by the sensing component exceeds a control threshold set for the vibration of the dewatering tank, the driving part enables the dewatering tank to rotate stably at a control rotating speed lower than the target rotating speed under the control of the control part, and the control part prolongs a dewatering period set corresponding to the target rotating speed. Therefore, the vibration of the dewatering tank can be reduced.

Description

technical field [0001] The invention relates to a dehydrating device for dehydrating clothes. Background technique [0002] Most kinds of washing machines are also used as a dehydration device having a dehydration function. Patent Documents 1 and 2 disclose a washing machine including a housing and a dehydration tank installed obliquely with respect to the housing. With the rotation of the dehydration tank, the clothes move greatly in the dehydration tank. [0003] Because the dewatering tank of the above-mentioned inclined drum type washing machine is inclined, clothes are easily collected at the bottom of the dewatering tank. Therefore, the washing machines disclosed in Patent Documents 1 and 2 include a vibration sensor in order to prevent excessive vibration caused by unevenness of laundry. Based on the output from the vibration sensor, the dehydration tank is controlled. [0004] Another type of washing machine includes a top-loading washing machine. The top-loadin...
