ものである。The above-mentioned conventional technology may cause problems if the selection of the driving mode is inappropriate or if the user forgets to switch the driving mode. For example, when cleaning a carpet, it is normal to use the carpet operation mode and set the output to increase the suction power. If the machine is operated in the normal operation mode, the air volume will not increase, and therefore the necessary suction force will not be obtained and power will be wasted, resulting in uneconomical operation, or the pressure will rise too much, causing operational problems. It was happening. In view of the above-mentioned problems, the present invention has been made with the object of providing a vacuum cleaner that is compatible with the various types of suction bodies used and that solves the novel problem of controlling the operation with an optimal operation pattern.

This is achieved by determining and recognizing the type of the suction body and automatically selecting the optimum operation control law for the suction body.

A vacuum cleaner body case 12 with a built-in dust collection filter 11
The basic part is composed of a vacuum cleaner main body 14 consisting of a dust collection case 13 containing a built-in dust collection case 13, a flexible hose 15, an extension pipe 16, and a suction body 20. It is electrically connected to the container 21 (FIG. 1).

流値から吸口体200種類を判別することができる。Alternatively, the same discrimination can be made by providing the extension tube 16 with a changeover switch 37 for switching the resistance value, which is provided on the extension tube 16 side opposite to the protrusion 35 provided on the suction body 20 to be connected as shown in FIG. FIG. 7 is a diagram showing another embodiment, in which coils 45 and 47 are provided facing each other on the extension tube 16 and the mouthpiece body 20 at the connection part of the extension tube 16 and the mouthpiece body 20, and the coils on the side of the extension tube 16 are provided. When a high frequency current is supplied to the coil 45 to generate a magnetic field, the current flowing through the coil 45 changes due to the interaction of the coil 47. That is, the mouthpiece 2
The type of suction body 20 can be determined by changing the impedance of the coil 47 for each type of suction body 0 and detecting the value of the current flowing through the coil 45. Furthermore, in FIG. 8, a high frequency current is passed through a coil 45 provided on the extension tube 16 of the connecting portion, and a magnetic body 49 is attached to the mouthpiece body 20. As a result, when the mouthpiece body 20 is connected to the extension tube 16, the magnetic body 49 changes the inductance of the coil 45, and the current flowing through the coil 45 changes. That is, the mouthpiece 20
If the length Q of the magnetic body 49 that enters the magnetic field is changed for each type, the current value of the coil 45 will also change accordingly, and the 200 types of suction bodies can be discriminated from this current value.

その運転制御則によって電動送風機4を運転制御する。As described above, the switching device 22 is switched according to the type of the suction body 20 identified by the discriminator 21, and the operation control law in which the best control law is stored is selected from the memory section 8.
The operation of the electric blower 4 is controlled according to the operation control law.

ような運転パターンで運転することが好ましい。Is the mouthpiece body 20 a floor mouthpiece? A wide variety of other types have been developed, including a gap mouth, a round brushed mouthpiece, a motor-driven brushed mouthpiece, and a turbine brushed mouthpiece. FIGS. 5 and 6 illustrate the performance when the machine is operated with a floor suction body and a gap suction body as representative examples among the various suction bodies 20. As shown by the solid line in Figure 5, a floor suction body generally requires a large suction force on the high air volume side, but for example, the floor suction body may stick to the floor surface, or when paper or sheet-like If something sticks to the device and the device becomes nearly sealed, it is preferable to reduce the suction force and operate with the characteristics shown by the broken line to prevent adsorption. Further, in the case of the gap suction body shown in FIG. 6, a large suction force is required even on the small air volume side, and it is preferable to operate with an operation pattern that further increases the suction force as shown by the broken line.

制御することにより、適正な掃除が実施可能である。As mentioned above, in order to perform proper cleaning, it is desirable to operate the suction body 20 according to an optimal operation pattern for each suction body 20. Since the operating patterns of the vacuum cleaner that are compatible with various types of suction bodies 20 can be assumed in advance, control rules for operating the electric blower 4 in various operating patterns are stored in the memory section 8, and the control rules for operating the electric blower 4 in various operating patterns are stored in the memory section 8, and the control rules for operating the electric blower 4 in various operating patterns are stored in the memory unit 8, and the control rules for operating the electric blower 4 in various operating patterns are stored in the memory section 8, and the control rules for operating the electric blower 4 in various operating patterns are stored in the memory section 8 and can be changed each time it is used. Appropriate cleaning can be performed by switching the control law and controlling the operation according to the type of suction body 20 to be connected.
