Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a power control device for a vacuum cleaner equipped with an electric rotating brush body called a power head or power brush and using a vacuum cleaner for flooring. It is something that can be done.

(cnPrior Art) Conventionally, power to 7F has been used for cleaning carpets, etc., and T structure d shown in Fig. 181 has been used.

In other words, in FIG. 1, Il+ is the vacuum cleaner main body which has a built-in fan motor (not shown) and a dust collector, and 12) is the pipe (31) and the vacuum cleaner main body (IIY is a bellows-shaped hose that connects 2). The core line of the row is growing. Front ffe pipe (31
Equipped with an electric rotating brush body at the tip of the T-floor suction @1
To supply power to this floor suction device, connect the same power plug (6) to the floor suction device outlet (51) provided on the vacuum cleaner body +11. It passes through the cord (7) connected to the hose (2) and is connected to two core wires at one end (2a) of the hose (2).Then, at the other end (2b) of the hose +27, it bends and connects to the cord built-in part (9) of the pipe +81. ), connect the floor suction device (41) via the cord (1 (l) fixed to the pipe (3)
connected to.

And such a floor suction tool (41 is the vacuum cleaner body fil)
If you use it together with 2, it will be more effective if you adjust the electricity charge a according to the purpose, and the control I8] Y hose and
Eve's joint part, TYZ, in other words, if done at hand, the usability will be improved.

Examples of this type of system are shown in Figures 2 and 6.
There is a configuration like this.

Trx, ie, ttn, is a power control lever that allows the variable resistance +121y]' in FIG. 5 to be changed. The brush drive motor 3 of the floor suction device (4) is the outlet (5) and the plug (6).
Connect the core wire of the fan motor (141) of the vacuum cleaner main body Ill+ (151 is the hose 12) through the cord 110+Y to the wiring inside the vacuum cleaner main body Ill, and connect the circuit type 5 such as the third cause. !; T, T connector. Also, the core wire of the hose (21) is connected to the variable resistor (121) provided on the bent pipe (8) and the switch Y- mark.

Therefore, = T variable resistance + 121 Y variable D By this, the charging current of capacitor αD is changed, the trigger timing of trigger element U is changed, and the bidirectional control rectifier element (19
The conduction time is changed. T7f, that is, T brush drive motor (13 and fan motor f141) connected in parallel with each other.
Conduction time'&flil! The power is controlled by aT. The core wire of the hose (2) is used as a lead wire to the variable resistance (12+) and the switch σe, so it is attached to a floor suction device (
To supply power to 4), a separate power cord +llj must be used. Therefore, during use, the upper two cords + lUl get in the way, making it difficult to use.

(C) Purpose of the Invention The present invention provides power supply to a floor suction device with a built-in rotating brush and electricity charges at the joint part of the port and the pipe, that is, the Trx hand part, using only two core wires in the hose. The purpose is to improve usability by doing so.

) Composition of the invention Power of the vacuum cleaner of the invention! The ITl control device is a vacuum cleaner with a floor suction device equipped with a dynamic rotating brush body, which has a built-in fan motor and is connected to the main body of the vacuum cleaner via pipes and hoses. The power control element of the motor and the control knob for controlling the phase side of the control circuit are installed near the joint between the pipe and the hose, and are connected in series with the rotary brush drive motor and the power control element of the power restriction circuit. A motor current detection element is installed inside the vacuum cleaner body.

The output of the motor current detection element causes the fan motor to move to the phase side.

An example The present invention will be described below with reference to a T-winding example shown in the drawings.

In Figures 4 and 5, (the opening is the main body of the vacuum cleaner, which houses the fan motor (14), the first control circuit, the dust collection part, etc. +21 is a hose with two cores IIA; The core wire is connected to the main body of the vacuum cleaner (
1) is connected to the first control circuit via the wiring inside.

(6) is a bent pipe with hose (2) and pipe (31)k
Connect the floor suction device (4) to the tip of the pipe (31).The core wire of the hose (2) is connected to the second control circuit (2z) built in between the hand control section installed on the bent pipe (6). is connected to the brush drive motor (13) through the power cord O1. (c) is a control knob of the second control circuit c2z, which is operated to control the second control circuit by the output of the second trigger circuit. Control circuit CI!
The conduction time of Z is controlled, and the power of the T brush drive motor (13) is controlled by connecting it in series to the $2 power control element □□□.

The brush drive motor J, the resistor ■, and the second power control element @ are connected in series, and the brush drive motor (131
A voltage proportional to the current flowing through the resistor (Figure 6) is applied across the resistor. This voltage Y 1st)! Insert into J circuit (b). The first trigger circuit (27+) performs full-wave rectification and waveform shaping on this voltage, generates a required trigger pulse using a one-shot multivibrator circuit, and outputs it to the gate circuit of the power control element 181 1?A. The output connects the first power control element (to) and applies a voltage (see @7 factors) to the fan motor I.

By controlling the brush drive motor (131), the fan motor f141Y is driven in almost the same phase (1, middle 13).
I can control aT. Although current detection was performed using the resistor c261, it is also possible to use a coil or the like.

(F) Effects of the Invention Since the power control element of the electric and vacuum cleaner according to the present invention has the structure as described above, the brush drive motor of the floor suction device can be controlled at hand using only the core wire of the hose and the wood. It becomes possible to control the power of the fan motor of the vacuum cleaner body. In addition, since the floor suction device can be used with the dedicated cord and cord, the usability is improved and the structure is simplified.
