Electric vacuum cleaner

Abstract

The invention provides an electric vacuum cleaner, which is provided with: a vacuum cleaning head provided with an electromotor performing rotation and drive of a rotary brush; a movement speed detection part detecting movement speed of the vacuum cleaning head; a circuit detecting part detecting ground state; an electric air blower making the vacuum cleaning head generate attraction force; a collection dust detection part detecting the attracted dust; a signal control part controlling the revolution of the electromotor and the electric air blower according to the movement speed detection part, the circuit detecting part, and the collection dust detection part. Therefore, the ground state can be mastered, making the revolution of the electromotor and the electric air blower collect dust optimally.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner used for cleaning in general households, etc., and particularly relates to control related to user's operability and usability. Background technique [0002] Conventionally, the operation time and operation speed of the reciprocating motion when the user operates the electric vacuum cleaner are calculated from the number of reciprocating motions of the cleaning head per unit time, and the like. In addition, for example, Japanese Unexamined Patent Application Publication No. 3-82430 (Patent Document 1) proposes an electric vacuum cleaner that sucks dust and the like by changing the suction force based on the calculated result. [0003] However, in the environment where cleaning is actually performed, the cleaning methods of users vary greatly, and there are various operating methods and processing methods. Therefore, cleaning methods vary greatly depending on conditions such as the user's life...

AI Technical Summary

Problems solved by technology

Therefore, there are cases where the performance of attracting dust, which is the original purpose of dust removal, is reduced, and even if the suction force is increased, the effect of attracting dust cannot be obtained.

As a result, there are problems such as loss of energy

[0005] That is to say, if the operation speed is slow, even if there is a lot of dust in the place to be cleaned, the suction force to attract dust decreases due to the reduction of suction force for dust removal, so that the original function of the electric vacuum cleaner cannot be satisfied.

In addition, there are problems such as the following: if the place to be cleaned is free of dust, even if the operation speed is increased to increase the suction force, it becomes a control that deviates from the purpose of the electric vacuum cleaner that attracts dust for cleaning.

For example, if the ground is a floor, even if the attraction force is increased, there may not be a large effect before and after raising the attraction force

On the other hand, for example, if the floor is carpeted, if the suction force is lowered, the dust removal performance will drop, so there may be cases where the dust cannot be sucked even if it is cleaned.

Therefore, there is a problem that dust cannot be completely removed by suction if only the suction is controlled in the above-mentioned ground state.
