Abstract

PURPOSE:To prevent such trouble as disconnection even if a cleaning hose is bent and stretched, etc., by controlling a central suction device so that suction force is supplied to a suction port to which the cleaning hose is connected in accordance with an output of a connecting signal. CONSTITUTION:A control circuit 60 controls opening and closing of an opening/ closing valve provided on a branch part of a piping 20, and allows a central suction device 10 and a suction port 30 to which a bellows hose 40 is connected to communicate with each other. Also, the control circuit 60 operates a motor 11 of the central suction device 10, in the case an attachable/detachable switch 42, a connecting switch 31, and an operating switch 50 become a turn-on state. The motor 11 of the central suction device 10 which receives an instruction from the control circuit 60 stops its rotation. As a result, suction force stops through the piping 20, the suction port 30, and the bellows hose 40, and cleaning of a room 19 by a multi-purpose brush 41 is finished. Subsequently, the bellows hose 40 from which the multipurpose brush 41 is removed is contained in a containing place. As a result, the attachable/detachable switch 42 is turned off, and the control circuit 60 recognizes it.

Although it is suitable for being bent and stretched, the wiring running inside the bellows hose has problems such as breakage due to bending and stretching. (2) Problems to be solved by the present invention The objective is to provide a central cleaner that does not cause problems such as disconnection due to bending and stretching of the bellows hose.

"Means for Solving the Problem" In view of the drawbacks of the prior art as described above, the inventors of the present invention, in order to solve the problem, developed a central cleaner that omitted the wiring itself that runs through the bellows hose, that is, a suction system. A central suction device that generates force, a plurality of suction ports provided corresponding to each room, piping that communicates each suction port with the central suction device, and a cleaning hose that is detachably connected to the suction ports. A central cleaner equipped with a connection switch that detects which of the plurality of suction ports the cleaning hose is connected to and outputs a connection signal to that effect, and an activation signal for the central suction device. an operation switch equipped with a transmitter that emits a signal; and a receiver that receives an activation signal transmitted from the transmitter; The present invention is characterized in that the central suction device is controlled to supply suction force to a suction port connected to a hose.

"Function" Below, the function of the central cleaner according to the present invention will be explained.

■ Select the most suitable suction port for the area you want to clean from among the multiple suction ports, and connect the cleaning hose to that suction port. Then, the connection switch outputs a connection signal.

■ When the cleaning hose is ready for cleaning, the operating switch's transmitter emits an activation signal, and the transmitter receives the activation signal.

■ When the receiver receives the activation signal, it controls the operation of the central suction device so as to supply suction force to the suction port to which the cleaning hose is connected in accordance with the output of the connection signal.
Then, the suction force generated by the central suction device is transmitted only to the suction port to which the cleaning hose is connected via the piping, and cleaning can be performed.
