【発明の詳細な説明】 本発明は電気掃除機に関する。[Detailed description of the invention] The present invention relates to a vacuum cleaner.

ンを妨げる要因となっていた。Conventionally, the remote control of a vacuum cleaner uses electricity #I
A low-voltage transformer was built into the main body of the horizontal remover, and a low voltage was applied to a conductor wire embedded in the hose to control the speed of the electric blower in the vacuum cleaner body using an operating section provided at the end of the hose. However, such a configuration requires an expensive low-voltage circuit for remote control, which is a factor that hinders cost reduction.

で安価に製作できるものである。That is, the present invention has a hand switch having two contacts that can be selectively switched to each other and a neutral position, and diodes connected to the two contacts in opposite directions, and a hand switch that controls the rotational speed of an AC electric blower. A DC motor that drives a variable resistor included in the speed control circuit to change its resistance value is connected in series to an AC power source, and either of the two contacts on the hand switch By selecting it, a current flows through the DC motor in a fixed direction determined by the diode, causing the DC motor to rotate, and this rotation changes the resistance value of the variable resistor provided in the speed control circuit. Correspondingly, the rotational speed of the AC electric blower changes steplessly. In addition, the two contacts of the hand switch are connected to guides in opposite directions, so by switching the two contacts, the direction of the current flowing to the DC motor can be reversed, and the DC motor can be reversed. The rotation speed of the AC electric blower can be increased or decreased. By returning the hand switch to the neutral position, current will no longer flow to the DC motor and the AC electric blower will rotate at a constant speed. In this way, the rotation speed of the AC electric blower can be adjusted steplessly by simply installing a DC motor that drives a variable resistor included in the speed control circuit and attaching a diode to the hand switch to allow current to flow through the DC motor. It can be manufactured at low cost since there is no need to provide an expensive low voltage circuit for remote control as in the past.

る等して、容易に実現できる。As a result, current flows through the DC motor (9) in a fixed direction via the diode (Dl), and the DC motor (9) rotates in a fixed direction. This DC motor (9) is mechanically linked to the variable resistor of the speed control circuit (7), so while the hand switch (4) is in contact (4a), the resistance value of the variable resistor remains constant. The rotational speed of the AC electric blower (8) is changed steplessly by the speed control circuit (η).If this state of barking is in the direction of speed increase, the hand switch (4) is reversed and the contact ( 4b) side, current flows in the opposite direction to the DC motor (9) through the diode (D), and the speed control circuit (9) rotates in the opposite direction.
The resistance value of the variable resistor 7) also changes in the opposite direction, and the rotational speed of the AC electric blower (8) becomes slower. In this way, by operating the hand switch (4), the rotational speed of the AC electric blower (8) can be adjusted steplessly. In order to link the DC motor (9) and the variable resistor of the speed control circuit (7), for example, an H paper-shaped volume may be used as a variable resistor, and the rotating shaft of this volume may be connected to the DC motor through an appropriate deceleration mechanism. This can be easily realized by configuring it to be rotated by an electric motor (9).

Since it is attached to the hand switch, the rotation speed of the AC electric blower can be adjusted steplessly without providing an expensive low-voltage circuit for remote control, and it can be manufactured at low cost.
