«The role of vacuum cleaners»

Next, the operation of the cleaner 1 according to the embodiment of the present invention will be described with reference to the drawings, mainly with reference to Fig. 2 and Fig. 3 .

For example, as shown in FIGS. 2 and 3, when the cleaner 1 is moved, the user moves the handle 26 with a handle pipe (not shown). During this movement, the handle 26 has an impact force such as a load on the entire cleaner body 2 and contact with other foreign matter. The load and the like are applied to the upper half body 26B of the handle 26 and the lower half body 26A of the handle.

Since the upper half body 26B is formed of a non-carbon resin part 2B which is softer than the carbon resin, it is slightly deformed by the load to absorb the impact. Therefore, the upper half body 26B can suppress the occurrence of cracks in the lower half body 26A which is relatively weak to the impact.

The lower half body 26A is formed of a carbon resin, so that the static electricity of the handle 26 can be released into the atmosphere, so the user grasps the lift At the time of 26, it is possible to prevent static electricity from flowing from the handle 26 to the user.

Further, the child straddles the cleaner body 2 with the vacuum cleaner 1 as a game, and the handle 26, the handle connecting portion 27, the dust collecting cover 25, the upper casing cover 24, and the exhaust hood which are located at the upper portion of the cleaner body 1. When the load is applied, the carbon resin parts 2A are made of a carbon resin and have strength, and the adjacent member and the member to be mounted are non-carbon resin parts 2B, so that they are made of non-carbon resin as described above. The component 2B absorbs the load and can suppress the crack of the carbon resin component 2A.

That is, the handle 26, the handle connecting portion 27, the dust collecting cover 25, the upper casing cover 24, and the exhaust cover 23 are all screwed to the upper casing 22 made of non-carbon resin such as ABS resin, or It is locked, so the load can be relieved by the upper casing 22.

Further, as described above, the handle 26 is formed by combining the lower half body 26A made of a carbon resin and the upper half body 26B of the handle made of a non-carbon resin, so that the load can be relieved by one member. Other components increase the overall strength. The handle connecting portion 27 is also formed by the handle connecting portion outer frame 27a as the carbon resin component 2A and the handle connecting portion inner material 27b as the non-carbon resin component 2B. Lift 26 the same effect.

A handle connecting portion outer frame 27a made of a non-carbon resin having a substantially V-shaped side view and a carbon provided inside the outer frame 27a of the handle connecting portion are connected to the left and right lower end portions of the handle 26. The handle connecting portion 27 is a combination of the resin connecting portion inner material 27b.

Therefore, the handle connecting portion 27 is made of a soft non-carbon resin on one side. By easing the stress in the connecting portion outer frame 27a, it is possible to suppress the occurrence of cracks on the outer side of the portion where the handle 26 and the upper casing 22 are connected, and the handle connecting portion inner material 27b made of a carbon resin can be used to connect the handle connecting portion. 27 The overall strength is improved, and the handle 26 is made thin and thin.

Further, the upper casing 22 to which the handle 26 is attached is made of a non-carbon resin having a lower modulus of elasticity than the carbon resin, and is made to have a large tensile elongation at break, whereby the elastic deformation can absorb the gripper 26 applied to the carbon resin. Load, vibration, and stress, so it can be made into high rigidity.

As described above, in the cleaner 1 shown in FIGS. 2 and 3, the handle 26, the handle connecting portion 27, the dust separating portion 42, the dust collecting cover 25, the upper casing cover 24, the exhaust cover 23, and the wheel 5 are provided. All of the carbon resin parts 2A having strength are attached to the upper case 22 and the lower case 21 which are non-carbon resin parts 2B, so that the non-carbon resin part 2B can be relieved of stress, so that the thickness can be reduced. The amount is lighter.

As a result, the cleaner body 2 can be made lightweight, and the cleaner 1 having high rigidity can be made.

«Modifications»

The present invention is not limited to the embodiments described above, and various modifications and changes can be made without departing from the spirit and scope of the invention.

In the above-described embodiment, the case where the carbon resin component 2A and the non-carbon resin component 2B are fixed by the screw member may be used, such as a fastening member other than the screw member, ultrasonic welding, or an adhesive. The other fixing methods are fixed to each other.
