  FIG. 7 is a cross-sectional view taken along the line AA in FIG. 6 and shows a state in which the vibration isolating rubber 70 is attached to the holding member 60. A projecting portion 70 e having a rectangular cross section is provided on the lower surface of the anti-vibration rubber 70. The upper portion of the protruding portion 70e that fits into the through hole 61a of the holding member 60 is enlarged in the radial direction with respect to the lower portion disposed inside the protruding portion 51c of the storage case 50.

  An engaging portion 70d that engages with a gap 61c (see FIG. 6) between the ribs 61b of the holding member 60 is provided on the peripheral surface of the protruding portion 70e. The anti-vibration rubber 70 press-fits the protruding portion 70e into the through hole 61a, and the engaging portion 70d is engaged with the gap 61c of the bottom surface portion 61. Accordingly, the vibration isolating rubber 70 is held by the holding member 60, and the vibration isolating rubber 70 is prevented from falling off.

  When the vacuum cleaner 1 is assembled, the vibration isolating rubber 70 is engaged with the holding member 60. Next, the electric blower 30 is inserted into the holding member 60 from the opening 60 a and abuts against the vibration isolating rubber 70. The concave portions 70a, the convex portions 70b, and the convex portions 70c of the anti-vibration rubber 70 are press-fitted into the bearing portion 32e, the concave portion 32f, and the exhaust port 32b of the electric blower 30, respectively. As a result, the bottom surface of the electric blower 30 is supported by the vibration isolating rubber 70, and the peripheral surface is covered by the peripheral surface portion 62 of the holding member 60.

  At this time, the elastic soundproof material 35 is sandwiched between the electric blower 30, the outer peripheral surface, and the inner peripheral surface of the peripheral surface portion 62. Thereby, the electric blower 30 and the holding member 60 can be prevented from being detached by the elasticity of the soundproof material 35.

  The holding member 60 into which the electric blower 30 is inserted is inserted into the storage portion 51 of the storage case 50 through the opening 50a with the fingers on the hook portion 63. At this time, the electric blower 30 is maintained in close contact with the anti-vibration rubber 70 by its own weight, and the anti-vibration rubber 70 is prevented from falling off. The holding member 60 is positioned at a predetermined position in the storage case 50 by the guide of the guide part composed of the protruding part 62c and the groove part 51d. Thereby, the electric blower 30 is stored in the storage case 50.

  At this time, the lower portion of the protruding portion 70e of the anti-vibration rubber 70 is disposed with a predetermined gap with respect to the inner peripheral surface of the protruding portion 51c of the storage case 50. Further, the leg portion 61d of the holding member 60 abuts against the bottom surface 51b of the storage case 50 so that the holding member 60 is placed on the bottom surface 51b, and there is a vertical gap between the bottom surface of the antivibration rubber 70 and the bottom surface 51b. It is formed. Thereby, the vibration transmitted to the storage case 50 via the anti-vibration rubber 70 can be reduced, and the vibration of the main body 2 can be further reduced.

  The upper cover 16 fitted to the electric blower 30 is attached to the upper surface of the storage case 50 via the cushioning material 18, and the duct 15 is attached to the upper cover 16. Thereby, the main-body part 2 of the vacuum cleaner 1 is assembled.

  In the vacuum cleaner 1 configured as described above, a negative pressure is generated in the dust collecting unit 20 by driving the electric blower 30, and dust on the floor surface is sucked from the suction port body 5 and flows through the extension pipe 4 and the connection hose 3. The air flow including dust flows into the dust collecting container 22 of the dust collecting unit 20 through the connection port 10a and the inflow port 22a, and forms a swirling air flow in the dust collecting container 22. The relatively large dust contained in the airflow is removed by the centrifugal force of the swirling airflow, and is accumulated in the dust collecting container 22.

  The airflow from which the large dust has been removed rises, and fine dust is collected by the filter 37. The airflow that has passed through the filter 37 flows through the exhaust passage 42 and flows out of the dust collector 20 through the dust collector exhaust port 42a. The airflow flowing out from the dust collection unit 20 flows through the duct 15 and is exhausted from the exhaust port 32b through the electric blower 30.

  The exhaust from the exhaust port 32 b passes through the soundproof material 35, absorbs the noise of the electric blower 30, and flows out from the openings 62 a and 62 b of the holding member 60. At this time, since the opening 62a facing the communication port 51a of the storage case 50 and the opening 62b apart from the communication port 51a are provided, the air volume can be increased and the work rate can be improved.

  The airflow passing through the opening 62 a flows through the duct portion 52 through the facing communication port 51 a and flows out of the storage case 50. The airflow passing through the opening 62b flows along the outer surface of the peripheral surface portion 62, flows through the duct portion 52 via the communication port 51a, and flows out of the storage case 50. The airflow flowing out from the storage case 50 is discharged to the outside from the main body exhaust port 10b.

  According to the present embodiment, the holding member 60 holding the anti-vibration rubber 70 on the bottom surface portion 61 covers the periphery of the electric blower 30 erected on the main body portion 2 and the latch disposed on the upper portion of the peripheral surface portion 62. Part 63. As a result, the electric blower 30 is arranged inside the holding member 60, and the holding member 60 is inserted together with the electric blower 30 into the storage case 50 with a finger placed on the hook 63. For this reason, the vibration-proof rubber 70 is prevented from falling off by the own weight of the electric blower 30, and the electric blower 30 can be easily stored in the storage case 50. Therefore, the assembly man-hour of the vacuum cleaner 1 can be reduced.

  Moreover, since the latching | locking part 63 is protruded and formed in the radial direction from the surrounding surface part 62, the latching | locking part 63 which hangs a finger can be formed easily. In addition, you may form the latching | locking part 63 by the recessed part or through-hole which were formed in the surrounding surface part 62. FIG.

  Further, since the elastic soundproof material 35 disposed on the peripheral surface of the electric blower 30 is sandwiched between the outer peripheral surface of the electric blower 30 and the inner peripheral surface of the peripheral surface portion 62, the electric blower 30 is caused by the elasticity of the soundproof material 35. And the holding member 60 can be prevented from being detached. Therefore, the electric blower 30 can be stored together with the holding member 60 in the storage case 50 more easily. Moreover, the electric blower 30 is lifted integrally with the holding member 60 with respect to the bottom surface of the storage case 50 by the exhaust of the electric blower 30, and the contact between the vibration isolating rubber 70 and the storage case 50 is reduced. Thereby, the vibration transmitted to the storage case 50 via the anti-vibration rubber 70 can be reduced, and the vibration of the main body 2 can be further reduced.

  Further, since the guide portion that guides the holding member 60 in the vertical direction is formed by the groove portion 51 d of the storage case 50 and the protruding portion 62 c of the holding member 60, the holding member 60 can be positioned and inserted into the storage case 50. . Moreover, since the guide part is provided at a position away from the airflow outflow part (duct part 52) of the storage case 50, it is possible to prevent a decrease in the air volume of the electric blower 30 due to the airflow being blocked by the guide part.

  Moreover, since the peripheral surface part 62 has the opening part 62a (1st opening part) which opposes an outflow part (duct part 52), and the opening part 62b (2nd opening part) opened in the position away from the outflow part, The work rate can be improved by increasing the air volume.

  Further, the leg portion 61 d of the holding member 60 abuts on the bottom surface 51 b of the storage case 50 so that the holding member 60 is placed, and a gap is formed between the vibration isolating rubber 70 and the storage case 50. Thereby, the vibration transmitted to the storage case 50 via the anti-vibration rubber 70 can be reduced, and the vibration of the main body 2 can be further reduced. The holding member 60 may be placed on the inner wall in contact with an arbitrary position on the inner wall of the storage case 50.

  In the present embodiment, the vacuum cleaner 1 is formed in a canister type in which the suction port body 5 is connected to the main body portion 2 that houses the electric blower 30 via the connection hose 3. May be a vertical vacuum cleaner provided integrally.

  According to this invention, it can utilize for the vacuum cleaner provided with the electric blower.
