Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner, and particularly to a handle provided on a vacuum cleaner body.

(Prior Art) Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 119370/1983, there has been known a vacuum cleaner in which a handle is provided on the top of the vacuum cleaner body so that it can be moved up and down or up and down. There is.

By the way, when holding a rod-shaped object, in many cases, it is considered natural to hold the rod-shaped object to the side of the body and in the front-rear direction with respect to the body, but the electric cleaning method described in the above publication This machine had a structure in which the handle part of the handle was perpendicular to the longitudinal direction of the vacuum cleaner body, so if the longitudinal direction of the vacuum cleaner body was turned forward or backward, the handle part would face left and right, making it difficult to grip. If the handle is facing forward or backward, the vacuum cleaner body is likely to hit your body. On the other hand, a structure in which the handle is fixed parallel to the longitudinal direction of the vacuum cleaner body is also adopted, but in some cases, and depending on the person, the handle is fixed at right angles to the longitudinal direction of the vacuum cleaner body. Sometimes it's easy to hold.

Also, vacuum cleaners are known that have a rotatable cord reel for winding and storing a power cord inside the vacuum cleaner body, but conventionally, a spring spring or an electric motor has been used as the drive source for the cord reel. ing. However, since using a spring spring or an electric motor would be expensive, a structure in which the cord reel is rotated manually may be considered, but even with this structure, a handle or the like for rotating the cord reel is required.

(Problems to be Solved by the Invention) As mentioned above, in conventional vacuum cleaners, the direction of the handle for carrying the vacuum cleaner body is constant with respect to the vacuum cleaner body, so it is difficult to set the handle in any direction. However, depending on the situation and depending on the person, there was a problem that it became difficult to hold.

In addition, conventional vacuum cleaners require a drive source such as a mainspring spring or an electric motor to rotate the drill reel, or a handle dedicated to rotating the drill reel, which results in an expensive problem. .

The present invention aims to solve the above-mentioned problems, and provides an electric vacuum cleaner in which the handle part of the handle can be oriented in any direction, and the vacuum cleaner itself can be easily carried in any situation. The purpose is to provide opportunities.

Furthermore, the present invention aims to simplify the structure for driving the cord reel and provide an inexpensive vacuum cleaner.

One end of an extension tube 64 is inserted and connected to a grip tube 63 provided at the other end, and a continuous tube 66 provided at a suction port body 65 is inserted and connected to the other end of this extension tube 64. Further, the power cord 48 is pulled out from the vacuum cleaner main body 1, and the plug 50 of the power cord 48 is connected to an outlet. Then, while holding the grip tube 63 of the hose 61, the vacuum cleaner main body 1 is moved as appropriate by the wheels 2 and the swivel ring 3 to perform cleaning, but the electric method 1! By driving the tI 113, dust sucked in from the suction port body 65 is guided to the dust collection chamber 8 in the cleaner body 1 through the extension pipe 64 and the hose 61, and is stored in the dust collection bag 10.

When the handle 30 is not in use, such as during cleaning, the handle 30 can be folded down and stored in the storage section 28 of the handle base 24, as shown in FIG. 2, so that the handle 30 does not get in the way.

Further, when the vacuum cleaner main body 1 is moved over a relatively long distance during cleaning or when it is stored, the vacuum cleaner main body 1 can be carried using the handle 30. Handle 30
To use the vacuum cleaner, the handle 30 is raised to protrude from the upper surface of the cleaner body 1, as shown in FIG. 1 J3 and FIG. 4. Then, C1, if necessary, grasp the handle 30 and rotate the handle base 24 to orient the handle 30 in a direction that makes it easier to hold. In particular, move the handle 30 in the longitudinal direction of the vacuum cleaner body 1, or When facing in a direction perpendicular to this longitudinal direction, the handle base 24 is held by the holding means 33 and does not rotate accidentally. In addition, as the handle base 24 rotates, the engagement groove 23 and the engagement protrusion 27 that constitute the holding means 33 change.
It is engaged and disengaged due to its elasticity.

For example, when carrying the vacuum cleaner main body 1 by positioning it on the side of the body, as shown in FIG.
If the handle 30 is oriented in the longitudinal direction so that the wrist is in a natural position, if the handle 30 is oriented in the front-rear direction with respect to the body, the vacuum cleaner body 1 will also be oriented in the front-rear direction and held close to the body. However, the vacuum cleaner body 1 is difficult to hit your body. On the other hand, even when you have to carry the vacuum cleaner body 1 with the handle 5 positioned in front of your body, if it is easier to hold the vacuum cleaner with the handle 30 facing forward and backward, you can use the handle 30 to carry the vacuum cleaner. It is best to place it in a direction perpendicular to the longitudinal direction of the main body 1.

In any case, the orientation of the handle 30 can be selected to make it easier to hold depending on the time, place, or individual preference.

In the above embodiment, the handle base 24 can be held in the rotational position where the handle 30 is parallel to the longitudinal direction of the cleaner body 1 and in the rotational position perpendicular to the longitudinal direction of the cleaner body 1, but of course, it is possible to hold the handle base 24 in other rotational positions. However, it may also be possible to retain it.

Also, when storing the power cord 48 after cleaning, etc.,
Grip the handle 30 and turn the handle base 24 in one direction. Then, the cord reel 46 also rotates integrally with the handle base 24 via the shaft body 25, and the power cord 48 is wound around the cord reel 46. In this way, a drive source such as a mainspring spring is not used. First, the cord reel 46 is manually rotated, and the handle 30 for rotating the cord reel 46 also serves as the handle 30 for carrying the vacuum cleaner main body 1, so it is possible to reduce costs and reduce the cost. can.

〔Effect of the invention〕
