(B) Prior art A vacuum cleaner with a vertical parts storage chamber formed at the rear of the vacuum cleaner body is described in Japanese Utility Model Publication No. 61-37387, but this vacuum cleaner has an upper case and a lower case. Since a separate component storage chamber is formed and the component storage chamber is integrated at the same time when the upper case and the lower case are fitted, the configuration becomes complicated, the number of used components increases, and assembly workability deteriorates. Therefore, it is conceivable to form a downward cylinder in the upper case and an upward cylinder in the lower case, and to form a parts storage chamber by fitting the upward cylinder and the downward cylinder at the same time when the upper case and lower case are fitted. It is difficult to fit the upward-facing cylinder and the downward-facing cylinder, and there is also a risk that when an external force is applied to the upper case, they may shift from each other, making it impossible to store the parts.

(c) Problems to be solved by the invention The purpose of the invention is to obtain a vacuum cleaner that has a simple structure, improves assembly workability, and has a parts storage chamber that allows parts to be stored smoothly at all times. .

(d) Means for Solving Problems The vacuum cleaner of the present invention has an equipment storage chamber equipped with an electric blower and a parts storage chamber with an opening on the top at the rear of the vacuum cleaner body, wherein the parts storage chamber is ,
The main body includes an upward tube projecting upward from the lower case of the main body, and a downward tube projecting downward from the upper case of the main body and fitting into the upward tube, the downward tube having a smaller diameter than the upward tube. It is characterized in that the fitting surface of the downward cylinder is a tapered surface inclined in the outer circumferential direction.

(e) Function The fitting surfaces of the downward tube formed on the upper case of the vacuum cleaner body and the upward tube formed on the lower case are tapered surfaces that are inclined toward the outer circumference, so that the upper case and lower case can be easily connected. By entering into each other during fitting and assembly, they are reliably positioned at a predetermined position and fitted. And since the fitted state of the downward cylinder and the upward cylinder does not shift, and the downward cylinder has a smaller diameter than the upward cylinder, parts such as the narrow suction port can be
It is smoothly stored in the parts storage chamber without being caught in the fitting portion between the downward cylinder and the upward cylinder.

It has 0. And upper case 3 and lower case 2
When mating, the upper end fitting surface 24 of the upward cylinder 23 enters the lower end fitting surface 28 of the downward cylinder 27,
At this time, the lower tapered surface 25 and the upper tapered surface 29 enter into each other to prevent positional deviation during assembly, and the upward cylinder 23 and the downward cylinder 27 are securely fitted to form a vertically long cylinder. The parts storage chamber 21 formed in this way is provided vertically at the rear right side of the equipment storage chamber 7, so that it is a flow path for the air after passing through the electric blower 4 to the exhaust port 6. It doesn't get in the way. This component storage chamber 21 is designed to store a narrow suction port 31, which is an attachment component, in the vertical direction from the top opening 22.

Next, the exhaust hole 6 is provided at the rear of the lower case 2, and the exhaust hole 6 is located in the same direction as the mold removal direction of the lower case at a position facing the upper case claws 39, 39 near the upper part of the lower case. The lower case claw portions 40, 40 are integrally formed in the rear direction of the lower case 2. The upper case rear wall 3 is located on both outer sides of the lower case claw 40 to a position facing the stand 38 of the upper case, and between the lower case claws 40 and 40.
A claw-receiving vertical wall portion 41 extending from the lower case 2 is formed at a position substantially in contact with the inside of the case 7 . The engagement of the claws 39 and 40 is achieved by pressing down the upper case 3 from above using the rear elasticity of the upper case 3 and the lower case 2.
The rear parts of the upper and lower cases 3 and 2 are deformed by the height of 9 and 40, and the deformation of the rear parts of the upper and lower cases 3 and 2 is restored when the upper case 3 is pressed down to the point where the positions of the claw parts 39 and 40 are opposite to each other. done by.

Thus, when the upper case 3 and the lower case 2 are fitted, the upper and lower end fitting surfaces 24 and 28 of the upward cylinder 23 and the downward cylinder 27 face each other and overlap,
By automatically entering and fitting along the upper and lower tapered surfaces 29 and 25, the vertically long parts storage chamber 21 is formed without any displacement during assembly. Moreover, since the diameter D ₁ of the upward cylinder 23 is larger than the diameter D ₂ of the downward cylinder 27, the narrow suction port 31 can always be smoothly stored in the parts storage chamber 21 without getting caught in this fitting part. Furthermore, even if the upper case 3 is bent due to external force applied when using a vacuum cleaner, etc., the upper and lower tapered surfaces 29 and 25 of the upward cylinder 23 and the downward cylinder 27 fit into each other, so that the fitted state is maintained. The narrow suction port 31 can be smoothly inserted and stored without shifting its position, maintaining airtightness.

(g) Effects of the invention According to the invention, the component storage chamber is simple in construction because the fitting surfaces of the downward tube of the upper case of the vacuum cleaner body and the upward tube of the lower case are fitted as tapered surfaces. The number of parts used is small, and when the upper case and lower case are fitted together, the upward cylinder and the downward cylinder can be fitted at the same time, resulting in very good assembly workability. Furthermore, even if the upper case is deformed due to an external force being applied to the upper case while using a vacuum cleaner, the fitted state of the upward cylinder and the downward cylinder will not shift, and the downward cylinder will be more stable than the upward cylinder. Since it has a small diameter, parts do not get caught in the fitting portion of the downward-facing cylinder and the upward-facing cylinder, so it has practical effects such as maintaining airtightness and allowing parts to be stored smoothly at all times.
