[0006]

The above-mentioned prior art has the following problems. In the prior art,
The handle body is rotatably attached to the cleaner body, and the handle body is bent and stored with respect to the cleaner body. However, since it is not locked in a bent state, it cannot be cleaned or carried while holding the handle body, and it is necessary to separately provide a main body handle for carrying, which results in poor appearance, usability, and high cost.

As the power cord, a cabtyre cord having a parallel two-core or a round cross section is used, but the parallel two-core is not suitable for an electric vacuum cleaner having a power consumption of more than 500 W, and has a round cross section. The cabtire cord has a large cord reel outer diameter and is not suitable for compact, high-power vacuum cleaners. Further, the outlet of the power cord has the rear surface of the cleaner main body facing sideways, so the plug pops out from the cleaner main body, the appearance is poor, and the outlet is in front of the user. The power cord may sag near the user's feet, which may be an obstacle or damage to the power cord.

Since the hose is completely separated,
It requires time and effort to insert into the vacuum cleaner body when used, and it is easy to disengage from the vacuum cleaner body, resulting in poor usability. On the other hand, in the case where the hose is provided with an engaging portion for attachment and detachment, a clamp, a spring, a cover, a screw, etc. are required, and the cost is high. If the hose is fixed to the side of the cleaner body that is in communication with the dust collection chamber, there is no need to insert it, but since the fixing point is located in the approximate center of the body,
Poor appearance, short hose usage range, and poor usability.
Further, as described in Japanese Patent Publication No. 6-75561, in which the suction port body is connected to the cleaner body, a separate piece such as a clamp, a spring, a cover, and a screw is required, which results in high cost and poor assemblability.

Further, since the clearance nozzle is a separate piece from the hose, when using the clearance nozzle, it is necessary to insert the clearance nozzle into the hose, resulting in poor usability and high cost. In addition, when hair is planted all around the opening of the clearance nozzle, it is costly, and there is a problem that the hair may fall into the opening and dust such as lint or hair is caught in the hair and removed. Since it takes time and effort, the usability is poor. If the clearance nozzle and the flocked body are separate pieces,
It takes time to put on and take off, and there is a possibility that the flocked body may be lost.

Further, since the exhaust lattice holes cannot change the exhaust direction, there is a problem that dust on the floor is rolled up or the user is exhausted depending on the state of use. As described above, the structure has poor usability and appearance and is costly.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide an electric vacuum cleaner provided with a rotatable handle, which has good operability and excellent usability. To do.

According to the invention of claim 1, since the handle body and the cleaner body are fastened to each other when the handle body is bent and put in the stored state, the handle body is disengaged from the cleaner body when the handle body is held. It can be carried around without any need for a separate handle and is highly usable.

According to the invention of claim 2, when the handle body is supported in a straight line with respect to the cleaner body, a normal stick type can be used, and the handle body is bent and stored with respect to the cleaner body. When you do, you can use the handy type by grasping the center part of the handle body and two ways to use with one unit. Furthermore, since the handle and the grip are integrally provided on the handle body, the appearance and usability are excellent, and there is a cost advantage.

According to the third aspect of the present invention, since the grip portion of the handle body coincides with the center of gravity of the cleaner body, it can be used with excellent stability and stability when used as a handy type. The property is improved.

According to the fourth aspect of the present invention, since the grip portion is provided in the wide gap portion having the substantially "V" shape, the hand touches the cleaner body when the handy type is used. Without, the grip portion of the handle body can be easily gripped.

According to the fifth aspect of the present invention, since one switch is provided on the handle body, the wiring process inside the handle body can be performed very easily and the assembling property is improved. It is also advantageous in terms of cost.

According to the sixth aspect of the present invention, since the power cord having the elliptical cross section is provided, the insulation distance is 0.8.
The above can be secured and the power consumption exceeding 500 W can be dealt with. Moreover, because of the oval flat shape, the cord reel can be made smaller in the outer diameter direction than the round shape. That is, it is indispensable for a compact and high-power vacuum cleaner.

According to the invention of claim 7, since the hose integrated with the connecting piece rotates with respect to the main body of the cleaner, the hose does not come off from the main body of the cleaner, and it is troublesome to remove the hose and insert it into the main body. Is unnecessary and excellent in usability.

According to the eighth aspect of the present invention, since the air flow direction can be changed by the louver structure in the exhaust lattice hole, the user can select an arbitrary exhaust direction. The vertical vacuum cleaner has a drawback in that it is very difficult to determine the direction of the exhaust, and if it is facing downward, it will wind up dust on the floor, and the exhaust will hit the user in the horizontal and upward directions. To solve this problem, a louver structure is used as a means of changing the wind direction.
