Problems solved by technology

[0007] However, when the toilet seat 20 or the toilet seat cover 40 is closed after defecation, it descends rapidly to resist the toilet bowl 10, producing a crashing sound.
The collision sound frightens the elderly or weak people, children, pregnant women and nursing mothers, etc. These toilet seats 20 and toilet seat covers 40 are also unsuitable for places where a quiet environment needs to be maintained.

Abstract

An apparatus for controlling a rotational movement of an opening and closing unit by using a counter electromotive force of a motor includes: a motor driving unit that drives an electric damper by driving a motor to operate the opening and closing unit; a position detecting unit that detects the position of the opening and closing unit operated by the motor driving unit; a power intercepting unit that receives a signal of detecting the position of the opening and closing unit from the position detecting unit, and cuts off power if it determines that the opening and closing unit is at a pre-set position based on the received position detect signal; and a counter electromotive force generating unit that generates a counter electromotive force of the motor when the power intercepting unit cuts off power.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling an opening and closing unit using a back electromotive force of a motor, and more particularly, relates to a method for controlling an opening and closing unit by generating a back electromotive force of a motor when the opening and closing unit of a rotary motion (ie, a reciprocating rotation operation) is closed. Apparatus and method for controlling opening and closing of a unit. Background technique [0002] refer to figure 1 A toilet seat (ie, a toilet seat) or a toilet seat cover provided at a general-purpose toilet (ie, flush toilet) is described as an example of an opening and closing unit that is rotatably (or pivotally) movable. [0003] figure 1 It is a perspective view of a related art toilet including a hot water washer (ie, a hot water cleaner). Such as figure 1 As shown, a toilet including a hot water washer includes a toilet bowl 10 disposed at a middle portion ...
