Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control system for a vacuum cleaner, and is applicable to various types of floor surfaces (for example, 1 tatami floorboard, carpet).

The present invention relates to a vacuum cleaner that cleans effectively and economically (energy-saving) with the minimum suction force that matches the type of dirt scattered on the floor.

Conventionally, the following types of energy-saving vacuum cleaners have been available: That is, an air volume sensor that detects the amount of air discharged from the exhaust side of the air blower motor is provided inside the vacuum cleaner body, and a detection signal detected by the air volume sensor is compared with a reference signal provided by a comparator.

There has been an attempt to automatically control the rotational speed of the blower motor so that the air volume is always constant, thereby cleaning the floor in a constant manner regardless of the type of floor surface.

In addition to the automatic control described above, a manual changeover switch is installed on the vacuum cleaner body, and the above ventilation can be controlled by operating the changeover switch and selecting ``strong'' or ``weak'' depending on the type or condition of the floor surface. There was one that manually controlled the rotation speed of the motor and attempted to clean with electricity that matched the floor surface.

However, in the former method, the control method automatically detects the condition of the floor surface and attempts to maintain the speed regulating motor at a constant rotation. Alternatively, a constant amount of power is consumed regardless of the light weight and minute dust that is easily inhaled, which causes a decrease in the energy saving effect, and the economical efficiency has not improved as much as expected.

In the past, the latter type had a changeover switch located on the vacuum cleaner itself, which caused problems with operability.

Furthermore, there were problems such as manual switching not being performed properly, which caused a decrease in economic efficiency.

This invention has been made for the purpose of improving this problem, and includes an air volume sensor that detects the suction air volume in the suction part, and a display g4 that displays the detected value of this air volume sensor, and the handle part of the flexible hose is equipped with a By providing an operable regulator and providing a blower motor control section that controls the rotation speed of the blower motor in response to this regulator, it is possible to control the rotation speed of the blower motor according to the condition of the floor surface. Therefore, we propose a vacuum cleaner with excellent economy and operability.

The vacuum cleaner of the present invention will be described in detail below with reference to one drawing.

FIGS. 1, 2, and 3 are component diagrams showing an embodiment of the present invention, and FIGS. 4 and 5 are block diagrams showing an embodiment of the invention.

In Figures 1 to 5, (1) is an air volume sensor that detects the amount of air flowing through the intake passage communicating with the intake port (6). It is used by an air volume sensor that converts a change in heat dissipation of an indirectly heated thermistor into resistance. (2) is a comparator having a reference signal to be compared with the detection signal from the air volume sensor (1), and (3) is a display that displays the result based on the output signal from the comparator (2). Diodes or sounds are used to distinguish between insufficient power (air volume is insufficient), appropriate power, and excessive power (air volume is excessive) and are displayed by lighting or changing the lighting color or changing the sound as necessary. (
4) is a DC power source consisting of a dry cell battery that supplies power to the airflow sensor (1), comparator (2) and indicator (3).

(5) is a brush part which is a suction part provided with the above-mentioned air volume sensor (1), comparator (2), indicator (3) and DC power supply (4).

(7) is an extension pipe, (8) is a flexible hose, (
9) is a handle provided at a predetermined position of the flexible hose (8), and (II is a regulator Q11 consisting of a switchable variable resistor arranged on the handle) spirally extends around the outer periphery of the flexible hose (8). The photocoupler (1) is connected to the photocoupler (1) through the connector (0) connected by the electrical transmission line wound in the shape of a
31 is connected to the operation adjustment section, (1 is connected to the photocoupler U3I, and is constituted by the resistor aη of the photocoupler Q31; α barrel is the ventilation motor.

(II has the photocoupler (I:1), transformer I, blower motor controller α, and blower motor α11, and supplies power to the blower motor α barrel, and trigger circuit α19.) An AC power supply is shown with a plug C!D supplying power to the lance Q41.

Note that t23 is a rotary brush provided in the brush portion (5), and (c) is a turbo fan for driving the rotary brush.

In the vacuum cleaner configured as described above.

The air volume sensor (11) installed in the brush part (5) corresponding to the suction port (6) detects the state of the floor surface to be cleaned and the type of garbage scattered on the floor surface, and displays the detected contents. The user is notified by the display (3) that the flexible hose (8
), the resistance value of the variable resistor with switch that constitutes the regulator αυ changes, and in response to the change, the photocoupler u
31'i The brightness of the incandescent bulbs that make up the lamp changes, and this change in brightness changes the resistance of Ode.

The rotation speed of the air blower motor (18) provided on the body 01 can be controlled.

Therefore, within the variable range of the variable resistor with a switch constituting the regulator U, the rotational speed of the blower motor Q frame, that is, the suction force can be freely controlled.

In the embodiment of the present invention, a dry battery is used as the DC power supply to each part of the brush section (5).

It is also possible to use a DC power source whose generation source is the rotational force of the rotary blades of the turbo fan (c) or the air volume sensor (1) constituting the brush portion (5).

As described above, the present invention includes an air volume sensor for detecting the suction air volume in the suction part and an indicator for displaying the detected value of the air volume sensor, and a manually operable adjuster in the handle of the flexible hose. By providing a blower motor control section that controls the rotation speed of the blower motor in response to the regulator.

The rotation speed of the blower motor can be controlled according to the condition of the floor surface. Therefore, fine control can be performed in response to changes in the state to be cleaned, and wasteful power consumption can be prevented, resulting in an energy saving effect and improved economic efficiency.

It is easy to operate because the adjuster is placed in the handle, and the suction force can be adjusted steplessly, so it has the advantage of being easy to operate and improving operability. ing.
