It is fixed in the state of being fixed. The opening / closing member accommodating portion 64 is configured by combining the pipe-side constituent portion 64a and the accommodating portion-side constituent portion 64b in this way.

The opening / closing member 66 is a member for opening / closing the pipe portion side opening 30a and the accommodating portion side opening 52c forming the opening 60. The opening / closing member 66 is slidably housed inside the opening / closing member accommodating portion 64 described above. The opening / closing member 66 has an opening / closing portion 66a, operating portions 66b, 66b, and an engaging portion 66c.

Specifically, the opening / closing member 66 is formed in a substantially "U" shape having a first component 66d and a second component 66e arranged substantially in parallel, and a third component 66f connecting the two. The plate-shaped portion forming the opening / closing portion 66a and the protruding portion forming the operating portions 66b, 66b are integrated with the member.

The distance between the first component 66d and the second component 66e is such that the opening forming portion 64c of the opening / closing member accommodating portion 64 described above can be sandwiched from the outside in the width direction. The thickness of the first component 66d and the second component 66e is set so that the opening / closing member accommodating portion 64 can be fitted between the opening forming portion 64c and the peripheral wall portion 64d with almost no gap. Therefore, the opening / closing member 66 has an opening formed by the first component 66d and the second component 66e inside the pipe-side component 64a in a posture in which the engaging portion 66c faces upward and the third component 66f faces downward.

The operation units 66b and 66b are exposed to the outside through the notches 64h and 64h, respectively. Therefore, when the user slides the operation portions 66b and 66b with a finger or the like, the opening / closing member 66 can be slid inside the opening / closing member accommodating portion 64 (pipe side component 64a) to open / close the opening 60. ..

The engaging portion 66c is a plate-shaped portion that projects further upward from the upper end side of the opening / closing portion 66a. As shown in FIG. 5, a convex portion 66g is formed on the back side of the engaging portion 66c. The convex portion 66g forms the system deconstruction portion 68 in combination with the concave portions 64k and 64l provided in the opening upper portion 64f of the pipe-side constituent portion 64a described above. The concave portion 64k is provided at a position where the convex portion 66g can be engaged by sliding the opening / closing member 66 to a position where the opening 60 (the opening 30a on the pipe portion side and the opening 52c on the accommodating portion side) is opened. Further, the concave portion 64l is provided at a position where the convex portion 66g can be engaged by sliding the opening / closing member 66 to a position where the opening 60 (the pipe portion side opening 30a and the accommodating portion side opening 52c) is closed. Therefore, the system deconstruction portion 68 switches between the engaged state in which the convex portion 66 g and the concave portions 64k and 64l are engaged and the non-engaged state in conjunction with the slide operation of the opening / closing member 66. Further, since the system deconstruction portion 68 is provided, the opening / closing member 66 can be fixed in the open state and the closed state of the opening 60, and the operation of opening / closing the opening 60 can be given a sense of moderation.

≪About the internal structure of the vacuum cleaner body 10≫
Subsequently, the internal structure of the vacuum cleaner main body 10 will be described. As shown in FIGS. 8 and 9, the vacuum cleaner main body 10 is assumed to accommodate the electric blower unit 110 inside the main body case 100.

As shown in FIG. 8, the main body case 100 has a housing portion 120 for accommodating the electric blower unit 110, a first protrusion 122, a second protrusion 124, and a second exhaust opening 126. The main body case 100 has a shape in which one end side is closed and the other end side is open toward the dust collecting portion 20. The electric blower unit 110 is housed in the accommodating portion 120 in a posture in which the intake side faces the dust collecting portion 20 side.

The first protrusion 122 is a protrusion that can support the elastic member 116 described in detail later. The first protrusion 122 projects inward in the radial direction of the main body case 100 at the portion where the accommodating portion 120 is provided. The first protrusion 122 is ribbed. The first protrusion 122 may protrude only in a part in the circumferential direction on the inner peripheral surface of the main body case 100, but in the present embodiment, it protrudes over substantially the entire circumference. Further, the first protrusion 122 may be provided only once or a plurality of the first protrusions 122, but in the present embodiment, the two first protrusions 122 are spaced apart from each other in the axial direction of the main body case 100. Is provided.

The second protrusion 124 is a protrusion that supports the fan portion 140 of the electric blower 114, which will be described in detail later. The second protrusion 124 protrudes inward in the radial direction from the inner peripheral surface of the main body case 100. The second protrusion 124 is ribbed. The second protrusion 124 may protrude only in a part in the circumferential direction on the inner peripheral surface of the main body case 100, but in the present embodiment, it protrudes over substantially the entire circumference. Further, the second protrusion 124 protrudes inward in the radial direction of the main body case 100 from the first protrusion 122 described above.

The second exhaust opening 126 is an opening provided on the peripheral surface of the main body case 100. The second exhaust opening 126 may be formed by a single opening, but in the present embodiment, it is composed of a plurality of slit-shaped openings. The second exhaust opening 126 is formed at a position radially outer with respect to the second case portion 132 of the electric blower case 112, which will be described in detail later.

When the electric blower unit 110 is arranged in the accommodating portion 120 of the main body case 100 as described above, a gap formed between the inner peripheral surface of the main body case 100 and the electric blower unit 110 is exhausted from the electric blower unit 110. Functions as a flow path (hereinafter, also referred to as “first flow path 125”) through which the air flows. Therefore, the second exhaust opening 126 functions as an exhaust port for discharging the exhaust flowing through the first flow path 125.

The electric blower unit 110 is made into a unit by accommodating the electric blower 114 inside the electric blower case 112 via an elastic member 116. The electric blower 114 is supported from the side by the electric blower case 112 via the elastic member 116 inside the electric blower case 112.

As shown in FIGS. 8 and 9, the electric blower case 112 has a cylindrical shape in which one end side in the axial direction is closed and the other end side is open. The electric blower case 112 is formed by integrally forming a first case portion 130, a second case portion 132, a third case portion 134, and a fourth case portion 136.

The first case portion 130 is a portion that closes the end portion of the electric blower case 112. The first case portion 130 is a portion that covers the electric motor portion 142 of the electric blower 114, which will be described in detail later, on one end side in the axial direction. The first case portion 130 is provided with a first exhaust opening 138 formed so as to communicate the inside and outside of the electric blower case 112. Further, the second case portion 132 is a portion forming a part of the peripheral surface of the electric blower case 112. The second case portion 132 is a portion that is continuous with the first case portion 130 and intersects with the first case portion 130 (substantially orthogonal to the first case portion 130). The second case portion 132 is a portion that covers the electric motor portion 142 on the radial outer side. Like the second case portion 132, the third case portion 134 is a portion forming a part of the peripheral surface of the electric blower case 112. The third case portion 134 is a portion that covers the fan portion 140 of the electric blower 114, which will be described in detail later, on the radial outer side. The fourth case portion 136 is a portion that gently connects between the second case portion 132 and the third case portion 134. The fourth case portion 136 has a tapered shape, and the diameter increases from the second case portion 132 side to the third case portion 134 side.

The electric blower 114 is a combination of a fan unit 140 and a motor unit 142. The electric blower 114 can drive the fan unit 140 and generate an air flow by energizing the motor unit 142. The electric blower 114 is arranged inside the main body case 100 and the electric blower case 112 so that the fan portion 140 faces the dust collecting portion 20 side (downward in this embodiment) and the electric motor portion 142 faces upward. ..

As shown in FIG. 8, in a state where the electric blower 114 is arranged inside the electric blower case 112, a flow path through which exhaust gas from the fan portion 140 flows between the inner peripheral surface of the electric blower case 112 and the electric motor portion 142. (Hereinafter, also referred to as "second flow path 144") is formed. Further, a first exhaust opening 138 is provided in the first case portion 130 on the downstream side of the second flow path 144. Therefore, as shown by an arrow in FIG. 8, the exhaust gas that has passed through the second flow path 144 passes through the first exhaust opening 138 to the first flow path 125 formed between the electric blower case 112 and the main body case 100. It is discharged, wraps around the outer peripheral surface of the electric blower case 112, and is finally discharged to the outside through the second exhaust opening 126. As described above, since a long exhaust path from the second flow path 144 to the second exhaust opening 126 via the first flow path 125 is formed inside the vacuum cleaner main body 10, exhaust noise can be suppressed to a minimum. The second exhaust opening 126 may be made closer to the fan portion 140 side. As a result, the exhaust path can be made longer.

An elastic member 116 is interposed between the fan portion 140 of the electric blower 114 and the above-mentioned electric blower case 112. The elastic member 116 is formed by using an elastic material such as rubber or silicone resin.
