Abstract

PURPOSE:To remove choked dust in a hose in a clean way by giving the same shape to both ends of the hose and by inverting the hose, that is, connecting one end of the hose connected with a socket to a floor nozzle side of a grip, and connecting the other end of the hose connected with the floor nozzle side of the grip to the socket. CONSTITUTION:A socket 4 provided with terminals 7, 8 which receive signal from a control unit 6 of a hose 5 sends a signal to an electronic circuit 10 of a body. Also, a pipe 11 is provided between the socket 4 and a dust chamber 3 as a path of suction air. As grips 9 are made at both ends of the hose 5, either grip 9 can be connected with the socket; the usability is improved. When the hose is choked with dust, if one end of the hose connected with the socket is connected to the floor nozzle side of the grip, and the other end connected with the floor nozzle side of the grip is connected to the socket, the direction of suction is as shown by the full line, and dust can be removed by the power generated in the direction of full line.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a vacuum cleaner that prevents clogging of a hose connected to an outlet of a vacuum cleaner body.

2. Description of the Related Art A conventional vacuum cleaner hose of this type will be described with reference to FIGS. 6 to 8.

In Fig. 6, 31 is the vacuum cleaner body, and the electric blower 3
2. It has a built-in dust collection chamber 33 and the like, and a hose 35 is connected to the insertion port 34 to collect dust. The insertion port 34 is also provided with connection terminals 37 and 38 for receiving signals from the control device 36, as shown in FIG.

FIG. 8 shows an outline drawing of the hose 35.

36 is a control device placed on the handle 39 on the floor nozzle side of the hose 35. By operating the control device 36, a signal is sent to the electronic circuit 40 of the main body 31 via the connection terminals 37, 38, and the electric blower 132 is activated. This is to control and adjust the suction amount.

Some modern vacuum cleaners have an outlet on the wall that allows the user to easily clean the vacuum by simply connecting a hose to the outlet. However, because the outlet was in a fixed position, it was not possible to clean the entire room without using a longer hose. At this time, the hose is more likely to become clogged with dirt than in a general vacuum cleaner, and the user has to be careful when cleaning the hose.

Problems to be Solved by the Invention With such a conventional configuration, in the event that dirt becomes clogged, a foreign object may be inserted into the hose in an attempt to remove the dirt, which may damage the inside of the hose. Ta.

In addition, there was a vacuum cleaner that could blow the exhaust air from an electric blower into the hose in order to prevent a clogged hose, but this method had the problem that the dust that spewed out from the hose would scatter and make the room dirty.

The present invention is intended to solve such problems, and aims to efficiently and cleanly dispose of clogging with dirt.

Means for Solving the Problems In order to solve the problems, the present invention provides a first means that includes: a vacuum cleaner main body having a built-in electric blower, a dust collection chamber, etc., an outlet into which a hose is inserted, the main body and the vacuum cleaner body; It consists of an air guide pipe that relays the outlet and a hose that has a built-in electric blower control device, and the dust is sucked into the dust collection chamber through the hose and the air guide pipe, and the outlet and the hose In the connected state, the control device is configured to be connected in a circuit to the main body, the input of the electric blower is adjusted by the control device to adjust the suction amount, and both ends of the hose have the same shape. Therefore, if the hose is clogged with dirt, reverse the hose connections, i.e., connect one end of the hose that was connected to the outlet to the floor nozzle side handle, and conversely, connect the other end of the hose that was connected to the floor nozzle side handle. A vacuum cleaner hose that can be connected to an outlet is provided, and in the second means, detachable pipes of the same shape are provided at both ends of the hose, and the detachable pipes are connected to the outlet. The pipe and the handle on the floor nozzle side are configured to be removable, so that when the pipe becomes clogged with dirt, the connection pipe that was inserted into the outlet can be connected to the handle on the floor nozzle side, and vice versa. Pipe can now be connected to the outlet.

With this configuration, if there is dirt clogging in the hose,
There is an outward force acting on the debris inside the hose, but by reversing the connection of the hose, that is, connecting one end of the hose that was connected to the outlet to the handle on the floor nozzle side, and conversely connecting it to the floor nozzle side. By connecting the other end of the hose that was connected to the handle to the outlet and reversing the intake direction, an inward force is applied to the garbage, reducing the size of the garbage, and the intake air flows into the dust collection chamber. It gets sucked in. Therefore, garbage can be disposed of without being scattered indoors.

The first method is to connect the entire hose in reverse, and the second method is to connect the detachable pipes at both ends of the hose in reverse.

Examples Hereinafter, a vacuum cleaner hose according to an example of the present invention will be described.
The explanation will be given with reference to FIG. 3.

FIG. 1 is a block diagram of the first means, in which 1 is a vacuum cleaner body, an electric blower 2. It has a built-in dust collection chamber 3, etc., and connects a hose 5 through an insertion port 4 to collect dust. Further, as shown in FIG. 2, the insertion port 4 is provided with terminals 7 and 8 for receiving signals from a control device 6 of the hose 5 and transmitting the signals to an electronic circuit 10 of the main body. Further, an air guide pipe 11 is provided between the insertion port 4 and the dust collection chamber 3 to constitute an air intake path.

FIG. 3 shows an outline drawing of the hose 5.

Reference numeral 6 denotes a control device placed on the handle 9 of the hose 5. By operating the control device 6, a signal is sent to the electronic circuit 10 of the main body via the connection terminals 7 and 8, and the electric blower 2 is controlled to adjust the suction amount. This is to adjust the In the present invention, since the handles 9 are provided at both ends of the hose 5, the user can connect either handle 9 to the insertion port 4, and usability is improved. In addition, as shown in Figure 4, when the inside of the hose 5 is inhaled in the direction of the dotted line, the dust A generates a force in the direction of the dotted line, that is, outward, and becomes clogged inside the hose 5. Connect one end of the hose that was inserted to the floor nozzle side handle, and conversely connect the other end of the hose that was connected to the floor nozzle side handle to the outlet, so that the intake direction will be as a solid line and the garbage will be removed. can remove dust by generating a force in the direction of the solid line.

FIG. 5 shows the configuration of the hose 5 according to the second method, and the detachable pipes 12 provided at both ends of the hose 5 can be attached to and detached from the connecting pipe 13 inserted into the insertion port 4 and the floor nozzle side handle 9 by means of the screws 14. The structure is as follows. The detachable pipe 12 is also provided with connection terminals 15 and 16 for wiring, and has the function of transmitting signals from the control device 6 to the main body 1.

As described above, the user can simply connect the removable pipe 12 in the opposite direction when the hose is clogged with debris. By connecting the connecting pipe that was inserted into the floor nozzle side handle to the insertion port, the force shown in FIG. 4 is applied to the garbage, making it possible to easily and cleanly remove clogged garbage.

Effects of the Invention As described above, according to the present invention, by configuring handles of the same shape on both ends of the hose, there is no need to worry about which end to connect to the outlet, and usability is improved.

In addition, in the case of dust clogging, the hose can be easily connected in the opposite direction as described above, so that the effect that dust can be efficiently and cleanly removed can be obtained.

Furthermore, it is expected that there will be cost benefits such as a reduction in the number of component molds.
