Abstract

PURPOSE:To make a flexible tube light in weight and to facilitate the handling by providing a receiver for receiving a signal transmitted from a radio transmitter on plural connecting ports provided in a building, operating the radio transmitter through the receiver and turning on and off a motor of the body. CONSTITUTION:A floor brush 55 is attached to the tip of an extension pipe 54 fitted to a tube 51, and by opening a cover 41 of a connecting port 4 of a room to which cleaning is started, a cleaning hose 5 is inserted. By an opening operation of this connecting port 4, the cover 41 is locked upward a little to the wall surface, and a receiver 42 of the reverse side is set to a receivable state. Also, the cleaning hose 5 is inserted into the connecting port 4, and the cleaning hose 5 is connected pneumatically to the body 7 of a motor-driven cleaner. In this state a radio transmitter 53 is removed from a holding part 52 and a power source key 53e is depressed, and thereafter, when a light emitting element 53a is turned to the cover 41 and a switching key 53d is depressed, the receiver 42 receives a code signal and a motor 75 of the inside of the body 7 rotates a fan 76 at a low speed, the inside of the body 7 becomes negative pressure, and refuse, etc., on the floor are sucked from the floor brush 55 and brought to dust collection into a dust collecting case 71 through a piping 6.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a central cleaner.

[Conventional technology] A central cleaner uses the main body of a stationary electric vacuum cleaner to collect dust centrally through connection ports installed at multiple locations in each room of a building, through pipes under walls and floors. It is configured. Normally, there is one connection port in each room, except for special large rooms. In addition, the cleaning hose consists of an extension pipe and a flexible tube.
A floor brush, crevice nozzle, etc. can be attached to the tip of the extension pipe so that they can be replaced. Therefore, this type of tube is usually made to be around 6 meters long, and since the cleaning hose is carried to each room one by one to clean it, the lighter the tube, the better.

Meanwhile, two wires are embedded inside the tube and are used as conductors for the hand switch.

If a metal such as a wire is embedded inside the tube, it becomes heavier and becomes difficult to handle.

In contrast, in the conventional devices of this kind, the actual situation is that no consideration is given to the above-mentioned measures for the weight of the tube.

[Problems to be Solved by the Invention] As described above, in the conventional central cleaner, no consideration was given to measures against the weight of the tube. As a result, approximately 6m of tubes, extension pipes, etc. must be carried to each room, which is heavy, inconvenient to handle, and tiring. Particularly in the case of a two-story building, having to carry a cleaning hose up and down the stairs is not only tiring, but also makes it easy to accidentally step off the stairs, which can cause serious injury. It is conceivable to prepare two sets of cleaning hoses and use them exclusively for each floor, but this poses problems such as being uneconomical due to extra cost.

The present invention was developed in view of the current situation, and has realized a central cleaner equipped with a flexible tube that is extremely light in weight and has no wires embedded in it, with a wirelessly operated hand switch. It is.

[Means for Solving the Problems] The present invention provides a receiver for receiving a signal transmitted from a wireless transmitter at the connection port, and operates the wireless transmitter via the receiver to collect dust from the main body. This is a central cleaner that turns the electric motor on and off.

[Operation] Open the lid of the connection port provided on the wall of each room, connect the cleaning hose, and then send an on signal from the wireless transmitter to the receiver placed on the back of the lid. Receive this signal. When the receiver receives an on signal, the dust collection motor in the main body rotates, and the dust on the floor is sucked into the hose. The dust that is sucked in is sent to the suction port of the main unit through piping and collected in the dust collection case. When cleaning is finished, the transmitter sends an off signal, which is received by the receiver and the motor stops rotating.

42> is set to a receivable state. Further, a cleaning hose (5) is inserted into the connection port (4), and the cleaning hose (5) is pneumatically connected to the main body (7) of the electric vacuum cleaner. At this point, remove the wireless transmitter (53) from the grip (52) and press the power key (53e), then turn on the light emitting element (53).
a) towards the lid (41>) and press the switch key (53d), the receiver (42) receives the code signal and the main body (7)
The electric motor (75) inside the body rotates the fan (7B) at low speed. When the fan (7B) rotates, negative pressure is created inside the body (7), and the dust on the floor is sucked in from the floor brush (55). The dust is collected in the dust collection case (7I) via the pipe (6).When you move on to cleaning the carpet floor, use the wireless transmitter (5)
When the high switching key (53b) of 3> is pressed to switch, the electric motor (75) rotates at high speed and the dust collection power is strengthened.

To move on to cleaning the next room, press the stop key (53f) to stop the electric motor (75>) and remove the cleaning hose (5).
Pull it out from the connection port (4) and carry it into the next room. Then, the cleaning hose (5) is connected to the connection port (4) of the next room, and cleaning is performed. Furthermore, the room on the second floor can also be cleaned using the same operation by carrying the cleaning hose (5).

In addition, in the above-mentioned embodiment, the wall (2) of the two-story house (1)
), (3) is explained by illustrating the case where the receiver 02) is installed, but it can also be used in buildings such as reinforcing bars or offices, and the cover of the connection port (4) with the receiver (42〉 installed on the floor) (41) may also be installed.In addition, although the explanation has been made for the case where the main body (7) of the electric vacuum cleaner is installed outside the building (1),
) The present invention can also be applied when installed inside. In addition, a display that displays the driving state of the electric motor (75) inside the main body (7) is attached to the grip part (52) of the cleaning hose (5>).
It is also possible to prevent forgetting to turn off the switch by providing it in an easily visible position.

[Effects of the Invention] As described above, the present invention provides a receiver for receiving a signal transmitted from a wireless transmitter at the connection port, and remotely controls the wireless transmitter via this receiver to collect dust from the main body. It consists of a central cleaner that turns on and off the electric motors used. As a result, it is no longer necessary to embed a wire for the conductor of the hand switch in the flexible tube, and the flexible tube can be made lightweight. Moreover, not only is the wireless operation convenient, but the flexible tube can be folded into a small accordion shape, making it compact and even more convenient to handle.

Therefore, according to the present invention, it is possible to realize a central cleaner that is light, compact, and extremely easy to handle.
