Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor moving type electric vacuum cleaner having a hose and an extension tube, and a structure for accommodating the electric vacuum cleaner with the hose, the extension tube and the floor nozzle connected to each other. Of the electric vacuum cleaner of.

2. Description of the Related Art Conventionally, a hose, an extension tube, a floor nozzle, etc. of a main body of an electric vacuum cleaner are attached and housed, as shown in FIG. It is general to disassemble each of the use nozzles 4 from the state of use and attach them to the main body 1 with a holding hook 5 or a claw (not shown).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the structure in which the floor nozzle or the like is mounted on the upper surface of the main body as described above, the hose 2 is shortened or the extension pipe 3 is detached from the hose 2 while the cleaner is being used. ,
It was necessary to separately fix the holding hooks 5 and the like, which was inconvenient.

Further, although the floor nozzle 4 is located at the upper portion as shown in the drawing when it is stored, it is unsanitary to store the floor nozzle 4 on which dirt and dust are attached by normal cleaning, and This makes the user feel uncomfortable when the floor nozzle 4 is contacted with the body when carrying the grip portion 6 after mounting.

Furthermore, since a heavy object such as the floor nozzle 4 is attached above, the stability during storage is poor and the object is prone to fall.

Therefore, the present invention is to prevent the electric vacuum cleaner from disassembling the hose, the extension pipe, and the floor nozzle, and preventing the floor nozzle from being located above and becoming unstable and unsanitary.

Means for Solving the Problems And, the technical means of the present invention for solving the above problems, a main body having front and rear wheels for movement in the bottom, a hose and an extension pipe via a connection pipe A floor nozzle is provided at one end of the extension pipe through the floor nozzle pipe at the other end of the extension pipe, a recess is formed in a part of the bottom surface of the main body, and a boat-shaped engagement is provided at a predetermined lower part of the recess. A section in which a stopper is provided so as not to protrude from the bottom surface of the main body, and the floor nozzle pipe is slid by using the recess as a guide and detachably engages with both outer sides of the boat-shaped locking piece. A pair of L-shaped clamps are provided so as to face each other.

Operation The effect of this technical means is to fix the floor nozzle, extension pipe, and hose to the main body that weighs more than the total weight. Therefore, keep the hose and extension pipe in the installed state as they are normally used. However, it does not fall down.

Further, since the hose and the extension pipe can be stored in the used state, it is not necessary to connect the hose and the extension pipe again at the time of the next cleaning. For this reason, preparation for cleaning and time for cleaning up are not required, and usability is improved. This storing operation can be done with one touch, which is very easy.

Further, by providing the concave portion on the bottom of the main body, the concave portion functions as a guide when the clamp is engaged, and the engagement can be smoothly performed.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3, reference numeral 7 is a main case having a front wheel 8 for movement on the bottom surface and a rear wheel 9 for movement on the rear bottom surface. Further, a dust lid 11 of the upper body 10 for covering the motor and the dust collecting chamber is arranged above the main body case 7. A hose 12 is attached to the front portion of the dust lid 11 via a connection pipe 13 and communicates with the dust collection chamber of the electric vacuum cleaner. Further, a floor nozzle 16 is connected to the end of the hose 12 via a tip pipe 14 and an extension pipe 15, and dust sucked by a suction force of a fan motor of an electric vacuum cleaner flows in from the floor nozzle 16. It passes through the extension pipe 15 and the hose 12 and is collected in the dust collection chamber.

Next, the configurations of the hose 12, the extension pipe 15, and the floor nozzle 16 will be described.

After cleaning, the hose 12, extension tube 15, and floor nozzle 16 are stored by forming a recess 17 in a part of the bottom surface of the main case 7, and a locking piece 18 molded in the shape of a ship in the main case 7 with screws 19. The locking piece 18 is attached so as to project from the outer bottom surface of the main case 7 so as not to be caught by a protrusion on the floor surface during use in a cleaning state. A pair of clamps 20 having an L-shaped cross section corresponding to the locking pieces 18 are integrally provided on the floor nozzle pipe 21, and the clamps 20 are accommodated by being engaged with the locking pieces 18. . The concave portion 17 provided on the main case 7 serves as a guide when the clamp is engaged, and the engagement is facilitated.

As described above, the electric vacuum cleaner has a hose 1 as shown in FIG.
2, The extension tube 15 and the floor nozzle 16 can be stored by standing upright with the same connection as when using.

As described above, the accessories (hose 12, extension tube 15, floor nozzle 16) are attached to the electric vacuum cleaner in a used state and stored without being disassembled, so that the user can hose after cleaning.
It is not necessary to pull out the extension tube 15 from 12 or remove the floor nozzle 16, so that the cleaning time after cleaning can be shortened. In addition, the operation to lock the main body can be performed with one touch, and it can be performed regardless of the length of the extension tube, so that there is an advantage that the adjustment operation becomes unnecessary.

Further, by providing the concave portion on the bottom of the main body, the concave portion functions as a guide when the clamp is engaged, and the engagement can be smoothly performed.

EFFECTS OF THE INVENTION The present invention has the following effects by storing accessories such as hoses, extension tubes, floor nozzles, etc. of an electric vacuum cleaner with one-touch with the accessories connected.

1. Since the extension tube and hose of the accessory can be stored without shrinking, it is not necessary to assemble the accessory the next time it is used. Moreover, it does not take time to store.

2. The storage operation can be done with one touch without the need to rotate other parts.

3. Since it can be used regardless of the length of the extension pipe, adjustment operations etc. are not required.

5. When the clamps are engaged, the concave part provided on the bottom of the main body functions as a guide, so that the engagement can be performed smoothly and the usability is good.
