Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an assembly structure for a vacuum cleaner.

Conventional configurations and their problems In conventional vacuum cleaners that are configured with an upper body and a lower body, screws are used to connect the upper and lower parts of the body both at the front and the back, which requires more man-hours for assembly and a large number of screws. , costs were rising.

To solve this problem, a device was devised in which claws were formed on the rear part of the upper body and the lower part of the body, and by engaging these claws, the work of tightening screws at the rear part and the use of screws were eliminated.

However, in this case, the work of joining the upper body and the lower body always involves a rotational movement in which the claws on the upper body and the lower body are first engaged, and then the front parts are assembled to fit together.

As a result, a new problem is that the rear tabs may become disengaged during assembly, making it difficult to assemble.Also, due to the rotational movement, the top of the body hits the bulkhead, and the end surface on the body causes the front of the support rubber of the electric blower to flip over. I got hot etc.

Purpose of the invention The present invention eliminates the drawbacks of the prior art, eliminates the need for connecting screws, and provides a vacuum cleaner that is easier to assemble.

Structure of the invention The vacuum cleaner of the invention has a built-in vacuum cleaner body with an electric blower and a cord reel arranged horizontally in parallel.
It consists of a partition wall that partitions the top of the body, the bottom of the body, the electric blower room, and the cord reel room. The front part of the partition wall is set in an arc shape so as to serve as a guide when the rear claw engaging part is used as a fulcrum to rotate on the body during assembly. An inclined rib is formed rearward from the front wall of the front wall.

Therefore, the main body can be assembled with a minimum number of screws, and the assembly itself can be carried out smoothly. Moreover, when the assembly is rotated, the rib on the body presses and holds the front of the support rubber of the electric blower to prevent it from turning over.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a vacuum cleaner main body incorporating an electric blower 2 and a cord reel 3, and is partitioned into an electric blower chamber 5 and a cord reel chamber 6 by a partition wall 4. The vacuum cleaner main body 1 is composed of an upper body 7 and a lower body 8, the rear part of which is engaged with a claw 9 and a recess 10, and the front part connected with a screw 11.

7a is the upper front wall of the body, 7b is the upper end surface of the body, 8
a is the lower front wall of the body. The shape of the front part 12 of the partition wall 4 is shaped to follow the rotation radius of the upper body 7, and when assembled, the upper body 7 may shift rearward and the claw 9
It is designed to guide you so that it does not come off. Further, an intake grid 13 is formed under the body 8 at the front of the electric blower chamber 5. An intake grid supporting rib 14 is provided on the body top 7 facing the center of the intake grid 13 to reinforce the intake grid 13. Furthermore, a reinforcing rib 15 is provided at the rear of the intake grid support rib 14 and is inclined in the direction of rotation of the upper body 7. Reference numeral 16 indicates a front support rubber that elastically supports the front part of the electric blower 2, and reference numeral 17 indicates a rear support rubber. In addition to reinforcing the intake grid support ribs 14, the reinforcing ribs 15 are designed to come into contact with the support rubber front 16 earlier than the end of the upper body 7 during assembly, thereby preventing the support rubber front 16 from turning up during assembly. ing.

A dust box 18 has a filter 19 installed therein. 20 is a roller, and 21 is a caster roller.

Effects of the invention According to the above embodiment, the top and bottom of the body are connected using a claw method, and even if assembly is performed by rotating the body, the claws can be prevented from coming off, and the parts cannot be hit by the rotation. , which can prevent the front of the support rubber from turning up, has great practical value, and in particular has great cost benefits by reducing assembly man-hours and screws.

Claims (1)

[Scope of utility model registration request] The vacuum cleaner body, which has an electric blower and a cord reel arranged horizontally in parallel, is composed of an upper part of the body, a lower part of the body, and a partition wall that separates the electric blower room and the cord reel room. It engages with claws formed on the top and bottom of the body, and the front part is secured with screws, and the front shape of the partition wall rotates on the body using the rear claw engagement part as a fulcrum during assembly. This vacuum cleaner has an arcuate shape that acts as a guide when the vacuum cleaner is moved, and an slanted rib extending from the front wall of the body toward the rear.
