Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electric vacuum cleaner, in which the power cord is housed by a simple means, and which has excellent handling, strength, reliability, and productivity. It is related to vacuum cleaners.

[Background of the invention]

The movable cord hook for storing the power cord installed in conventional vacuum cleaners holds the rotation axis of the cord hook rotatably between the main case and the handle, and also attaches the angle regulating stopper to the main case or the handle. The structure is such that when a force is applied to the end of the cord hook on the side, force is applied in opposite directions to two places, the one-turn axis and the angle regulating stopper. In other words, since force acts in the direction in which the main case and the handle open upward and downward, it is necessary to strengthen the tightening force between the main case and the handle and to strengthen the rotation shaft of the cord hook.

For this reason, it is necessary to increase the number of tightening screws on the main body case and handle, and to provide screw tightening positions near the rotation axis of the cord hook and the angle regulating stopper.Furthermore, force is applied to the cord hook. In order to strengthen the rotating shaft by enlarging the diameter of the shaft or making the details a separate part and using a steel ring, the material cost and number of parts will increase by increasing the thickness of the parts and adding reinforcing ribs, etc. This caused an increase in costs, such as an increase in direct material costs and a decrease in assembly workability.

Even with the above-mentioned reinforcement, it is very difficult to completely prevent the main case and the top and bottom of the handle from opening, and there are problems with reliability in terms of strength.

In addition, installing multiple tightening screws for the main body case and handle near the rotation axis of the cord hook and the angle regulating stopper section greatly restricts the external design, and also There are factors that greatly reduce assembly workability.

As mentioned above, there are problems with increased material costs and strength.

There were many drawbacks such as design limitations and reduced assembly workability.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to provide excellent strength and reliability, a simple structure, excellent assembly workability, a design that meets customer needs, and an inexpensive power cord. To provide a vacuum cleaner equipped with a movable cord hook for storage.

[Summary of the invention]

The present invention has a carrying handle fixed to the upper part of the main body case, and a cord hook for hanging the power cord when stored.Usually, the cord hook is stored so that it does not protrude from the outer periphery of the handle, and the power cord The cord hook is rotatable so that it can be put in and taken out when the cord is stored, and angle regulating stopper parts are provided before and after the rotation axis of the cord hook. The force applied to the end of the cord hook for hooking the cord acts on the two angle regulating stoppers, and no force is applied to the rotation axis, and the two angle regulating stoppers are attached to the inner surface of the main body case. and the upper surface, and since the force acts only on the main body case, it can be manufactured to be strong. For this reason, the handle has a structure that does not require a large amount of tightening strength to prevent the cord hook from falling off and to be used for carrying.

[Embodiments of the invention]

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

Sea urchin case part 3 consisting of main body case 1 and M base 2
An electric blower 4 is built in. A tank 5 is removably attached to the lower part of the sea urchin case part 3, and a suction port 6 to which a hose (not shown) is connected, casters 7 for traveling, and jarins 8 are also attached. Further, a filter 9 for filtering and collecting dust is provided between the tank 5 and the M base 2 through a gasket 10 so as to maintain airtightness between the tank 5 and the M base 2.

A handle 11 is attached to the upper part of the main body case 1. The U-shaped bearing groove 1a that holds the rotating shaft 12a of the cord hook 12 and the holding part (A) lb and holding part (B) lc that regulate the opening angle of the cord hook 12 are provided at the rear upper part of the main body case 1. It is formed integrally with the main body case 1. Further, a protrusion 1d having an elastic structure and urging the cord hook 12 into the stored state is provided near the bearing 1a. The handle 11 has a cord hook 1 at the shaft holding part 11b.
2 is secured to the main body case 1 with screws 14.

The cord hook 12 has an angle regulating stopper (A) 12b and an angle regulating stopper (B) 12c that abut the holding part (A) lb and the holding part (B) lc of the main body case 1, respectively, on the front and back of the rotation shaft 12a. It is provided. Further, a protrusion 12d that engages with the storage positioning protrusion 1d is formed on the rotation shaft 12a.

Reference numeral 13 denotes a power cord, and the hook is stored in the cord hook 12.

When using the vacuum cleaner, the cord hook 12 is stored in the cord hook storage recess 11a of the handle 11, and is configured so that it does not protrude from the handle 11, and the rotation axis 1
The protrusion 12d of the main body case 1 is urged into the stored state by the protrusion 1d of the main body case 1.

When storing the power cord 13, the cord hook of the cord hook 12 raises the portion 12s. The angle regulating stopper (A) 12b and the angle regulating stopper (B) 12c of the cord hook 12 are attached to the holding part (A) lb on the inner surface of the main body case 1.
and is held by contacting the holding portion (B) lc on the upper surface.

In this state, a gap is provided between the rotating shaft 12a of the cord hook 12, the shaft holding part 11b of the handle 11, and the bearing 1a of the main body case 1, and the force applied when the cord 13 is stored in the cord hook 12 is , is received by the holding portion (A) lb and holding portion (B) lc of the main body case 1, and has a structure in which no force acts on the rotating shaft 12a.

〔Effect of the invention〕

According to the present invention, the angle regulating stopper parts provided before and after the rotation axis of the cord hook come into contact with the inner surface and the upper surface of the main body case, respectively, so that all the force of the cord book acts only on the main body case, making it strong. It has a simple structure and excellent reliability. Moreover, it is possible to make an inexpensive vacuum cleaner with a small number of parts and good assembly workability.
