Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper for an electric vacuum cleaner used in general households.

[0002]

2. Description of the Related Art An electric vacuum cleaner of this type has hitherto been disclosed in JP-A-1-30.
The configuration is as shown in Japanese Patent No. 7011.
The configuration will be described below with reference to FIGS. 6 and 7.

The cleaner body 1 (hereinafter simply referred to as "body") has a fan motor, a cord reel, etc. inside the rear,
Further, the front half is a dust collecting chamber 17 whose upper part is open. 1
Reference numeral 8 is a lid for opening and closing the upper opening of the dust collection chamber 17, and 19 is a front cover having an intake port 20. Inside the intake port 20, a power supply terminal 21 for energizing an electric motor built in a floor nozzle connected via a hose / extension pipe (not shown) is attached. Reference numeral 22 denotes an intake port cover that covers the intake port 20 so as to be openable and closable.

A bumper 23 is provided on the side surface of the main body to cover most of the height. The bumper 23 is configured by using an elastic body such as rubber, and acts as a cushioning material that weakens the impact force generated when the main body 1 is operated and collides with furniture or the like. The bumper 23 is attached so as to fit into the opening edge of the dust collection chamber 17.

FIG. 7 shows a detailed structure of the bumper 23. The bumper 23 is integrally provided with a lip 24 that is a thin portion on the contact surface with the dust collection chamber lid 18. That is, the lip 24, which is a thin portion when the dust collection chamber lid 18 is closed, has elasticity, and thus has an airtight structure.

[0006]

The electric vacuum cleaner having the conventional structure has problems that the operation of the main body 1 is heavy and that the mounting work of the bumper 23 is difficult. That is,
The bumper 23 uses an elastic body such as rubber in order to protect the furniture and the main body 1 from an impact when they come into contact with furniture or the like. Therefore, when it comes into contact with furniture or the like during cleaning, the frictional resistance with the furniture is very large. That is, in such a case, the hose or the like connected to the main body 1 must be strongly pulled. Further, the outer surface of the main body 1 is formed in a curved shape in consideration of appearance and the like, and the mounting work for mounting the bumper 23 on this surface is very difficult.

Further, the intake port 20 for connecting the hose provided in the front portion of the main body 1 has a power supply terminal 21 for energizing the electric motor of the floor nozzle. Therefore, if a metal object such as a needle is struck in, there is a danger of electric shock, and the intake port 20 is covered with the intake port cover 22 when the cleaner is not used. That is, the conventional structure requires the intake port cover 22.

The present invention solves the problems of the conventional structure, and it is a first object of the present invention to provide an electric vacuum cleaner in which a bumper can be easily attached and the main body can be easily routed. I am trying. Further, in particular, it is a second object to provide an electric vacuum cleaner in which the bumper can be easily attached and the assembling workability is good. Further, a third object is to provide a safe electric vacuum cleaner having a simple structure and having no fear of electric shock.

[0009]

The first means of the present invention for attaining the first object is provided with an electric blower and a motor chamber provided with a cord winding device in the rear part, and the first part is provided in the front part. A main body having a dust collecting chamber provided with a dust filter and having an upper opening, and a lid provided openably above the dust collecting chamber,
The electric vacuum cleaner has a bumper made of an elastic body having a protective material having a good slipperiness adhered to the outer periphery of the open portion of the dust collecting chamber.

Further, the second means of the present invention for achieving the second object is, in particular, a cover provided with a projecting portion for locking one end of the bumper and a suction port at a substantially central portion in the front portion of the main body. A locking member having a locking portion on one surface is fixed to the other end of the bumper, and a locked portion is provided on the side surface of the main body for detachably locking the locking portion of the bumper. This is an electric vacuum cleaner in which members are fixed.

The third means of the present invention for achieving the third object is, in particular, that the bumper has a suction port of the cover when the other end is inverted while the one end is locked to the locking portion of the main body. The length of the electric vacuum cleaner is such that it covers only one side and the locking member is fixed to both surfaces of the other end.

[0012]

The first means of the present invention is that the protective material provided on the surface of the bumper provided on the outer periphery of the open portion of the dust collecting chamber reduces the frictional force when the main body comes into contact with furniture or the like, so that the operation can be performed. It works as a light vacuum cleaner.

A second means of the present invention is such that one end of a bumper is locked to a protrusion of a cover provided at the front of the main body and the other end of the bumper is detachably engaged with a locked member provided on the side surface of the main body.
