Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum cleaner equipped with a cord reel for winding up a power cord, and particularly to a vacuum cleaner that can be used with various power plugs.

[Conventional technology]

Conventionally, in vacuum cleaners with cord reels,
If the plug protrudes from the main body case with the cord wrapped around it, it may come into contact with surrounding furniture or walls while moving and cause damage, or it may hit and injure the user. There was one in which the plug could be stored in a recess provided in the main body case (Utility Model Publication No. 48-2438, Utility Model Publication No. 48-2438,
-Refer to Publication No. 39185).

On the other hand, the shape and dimensions of power plugs vary depending on the standards of each country, and also vary depending on the manufacturer. For this reason, depending on the shape of one plug,
When determining the depth of the plug storage, if you use a different type of plug, the plug may not fit into the plug storage and stick out, or it may go too deep into the plug storage, making it difficult to pull out the plug. There were some shortcomings.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a vacuum cleaner equipped with a plug accommodating portion that allows the plugs to be accommodated at approximately the same depth even when different types of plugs are used.

[Means for solving problems]

In order to achieve the above object, the present invention includes a cord reel, a cord wound around the cord reel, a plug provided at the tip of the cord, and a housing for storing the plug in a main body case of a vacuum cleaner. a plug storage box provided in the vacuum cleaner main body case, a plug stopper provided at the back of the plug storage box and forming the bottom surface of the plug storage box, and a cord hole provided in the plug stopper. The plug abutting part of the plug storage box is divided into two parts, and pins are removably provided on the cord storage side of the plug abutting part at intervals smaller than the cord hole, and the structure is simple and meets the standard. It can be used in different countries, and the power cord plug is stored in the main case.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. In the figure, reference numeral 1 denotes a main body case that is divided into left and right halves, into which a cord reel 3 of an electric blower and the like are incorporated. 4 is a dust case located in front of the main body case 1 and equipped with a filter device 5.

A substantially rectangular cord pull-out hole 7 for pulling out the power cord 6 wound around the cord reel 3 is provided in a part of the rear surface of the main body case 1.
A substantially box-shaped cord storage box 8 made of an elastic material such as plastic is inserted into the cord extraction hole 7, and has a space inside thereof into which the power cord 6 can completely enter. The front end (outside) of the cord storage box 8 is provided with a flange 9 which is larger in size than the cord extraction hole 7 and whose opening has a smooth curvature, and a pair of engaging fittings are provided on both sides. A protrusion 10 is provided, and the surface of the engaging protrusion 10 facing the flange 9 is perpendicular to the side surface of the cord storage box 8, and the opposite surface is an inclined surface. When inserted into the cord pull-out hole 7 of the case, the engaging protrusion 10 is elastically deformed along the inclined surface, and when it gets over the side wall of the cord pull-out hole 7, it returns again and engages the flange 9 and the engaging protrusion 10.
The cord storage box 8 is fixed to the main body case by sandwiching the side walls of the cord pull-out hole 7. In order to ensure the elasticity of the engagement protrusion 10, U-shaped slits 11 are provided on three sides around the engagement protrusion 10.

The rear end of the cord storage box 8 is open so that the power plug 6' can pass through, but there are protrusions 1 on both side walls.
2, and a groove 13 that engages with this protrusion 12.
The structure is such that it can be attached by inserting a cord stopper 14 equipped with a cord stopper 14 from above. This cord stopper 14 can be divided into left and right halves, and is divided into cord stoppers 14' and 14''.The power cord 6 can pass through the left and right cord stoppers 14' and 14'' in the center, respectively. Large plugs 6' (e.g. European type, Australian type plugs) are equipped with an appropriately shaped cord hole 15 that does not pass through, so that when the plug 6' and the cord 6 are wound up on the cord reel, the plug 6' is retracted. It is designed to be pulled into the box 8 to an appropriate depth and then stopped.

At the rear of the cord stopper 14', 14'', two protrusions 18 are provided on the left and right ends, and each of the protrusions 18 is provided with a pin receiving hole 19 that opens oppositely on the left and right. When the cord stopper 14', 14'' is assembled into the plug storage box 8, the stopper pin 20 can be inserted into the pin receiving hole 19 and supported while being attached.

A notch 18 large enough to receive the power cord 6 is provided at the rear end of the top surface of the plug storage box 8. Ribs 16 and 17 are provided on the upper and lower sides of the cord pull-out hole 7 so as to be close to the plug storage box 8 and are integral with the main body case to prevent the plug storage box 8 from shaking in the vertical direction. The cord stopper 14 prevents the plug storage box 8 from slipping out.

To explain the assembly order in the above configuration, after assembling the cord reel 3 incorporating the power cord 6 into a predetermined position inside the main body case, the power plug 6'
Penetrate the cord pull-out hole 7 and pull it out to the outside of the main body case 1. Next, divide the cord stopper 14 into two, pass the cord 6 through the cord hole 15, and then pull the plug 6' from the rear of the plug storage box 8 to the front. After passing the power cord 6 through the notch 18, the cord stopper 14 is fitted into the plug storage box 8 by fitting the protrusion 12 and the groove 13. After that, if the plug storage box 8 is inserted into the cord extraction hole 7 of the main body case 1 from the outside, it will be fixed by the engaging protrusion 10 and the flange 9, and the cord stopper 14 will also be held down by the rib 16, so that it will not come out.

Next, as shown in FIG. 5, a case will be explained in which a relatively small plug 6'' is used. For example, a relatively large plug 6' such as a European type plug is used.
If the dimensions of the cord hole 15 are determined so that the cord can be completely stored in the plug storage box 8 as shown in Figure 4, and if an American or Japanese type plug 6'' is used, the plug 6'' will be as shown in Figure 5. Cord hole 15
It passes through. In that case, by inserting and mounting the two stopper pins 20 into the two pairs of pin receiving holes 19 at the rear of the cord stopper 14, the plug 6'' that has passed through the cord hole 15 is inserted into the gap between the two stopper pins 20. The gap between the upper and lower pin receiving holes 19 is selected to be an appropriate gap that allows the cord 6 to pass through but does not allow the plug 6'' to pass through. In addition, by appropriately selecting the position of the pin receiving hole, the storage depth can be set to the optimal depth for use even when using a 6" plug. Therefore, depending on the size of the plug, the storage depth can be set to the optimal depth for use. Various types of plugs can be easily used by simply attaching or removing the stopper pin without using a cord stopper.
