  Further, as shown in Patent Document 1, the support structure in which the vicinity of the center of gravity is supported by a spring and the vicinity of the intake port is supported by a vibration isolator is suitable when supported by static conditions, steady vibration, or the like. However, when the above impact force is applied to the vacuum cleaner body, the position of the anti-vibration material near the intake port is shifted, the air blower and the dust collection chamber cannot be kept airtight, and the dust collection performance is deteriorated. there were. In addition, deformation of the vibration isolator has a problem in that the vibration isolating effect is reduced and noise is increased.

  An object of the present invention is to provide a cleaner with low noise.

  The present invention includes an electric blower that sucks dust, a dust collection chamber that collects dust, a motor case that houses the electric blower, an electric blower chamber that houses the motor case, the dust collection chamber, and the electric drive In a vacuum cleaner having a partition that partitions the blower chamber, and a vacuum cleaner body in which the dust collection chamber and the electric blower chamber are formed inside, the vibration isolation for the electric blower that supports the motor case in a vibration-proof manner. And an anti-vibration material for a motor case that supports the motor case on a vacuum cleaner body.

  According to the present invention, a low noise vacuum cleaner can be provided.

  Embodiments of the present invention will be described below.

  An embodiment of the present invention will be described with reference to the drawings shown below. FIG. 1 is a cross-sectional view of a plane of a vacuum cleaner main body passing through a rotating shaft of an electric blower, an upper main body case, and a lower main body case. FIG. 2 is an external perspective view of the electric vacuum cleaner. FIG. 3 is an exploded perspective view in which the upper main body case and the middle case shown in FIG. 2 are disassembled. FIG. 4 is an enlarged view of the motor case portion shown in FIG. FIG. 5 is an exploded perspective view of the electric blower chamber shown in FIG. FIG. 6 is an external perspective view of the motor case portion from the air inlet side shown in FIG.

  The vacuum cleaner main body 1 shown in FIG. 2 includes an electric blower 30 and includes a dust collection chamber 12 that collects dust at the front. The hose 2 is connected to the dust collection chamber 12 of the cleaner body 1 and is formed so as to move flexibly. The hand operating unit 3 is connected to the cleaner main body 1 via the hose 2, has a switch for controlling the cleaner main body 1 and the suction mouth 5, and is connected to the suction mouth 5 via the extension pipe 4. A path is formed and connected. The suction port 5 has a suction port (not shown) on the cleaning surface, sucks dust on the cleaning surface, and passes through the extension pipe 4, the hand operation unit 3, and the flow path inside the hose 2. It is connected to the dust collecting chamber 12 of the cleaner body 1. The extension pipe 4 has a built-in power supply line (not shown) for supplying electricity to the suction port 5.

  The vacuum cleaner sucks dust together with air from the suction port 5 by the suction force when the electric blower 30 is driven, and the sucked air and dust are passed through the extension pipe 4, the hand operating section 3 and the hose 2. The vacuum cleaner body 1 sucks the dust, and the dust is collected by the dust bag 15 attached to the dust chamber 12. Fine dust that has not been collected by the dust bag 15 is collected by the filter 37 installed at the exhaust port of the motor case 9, and the air is exhausted outside the cleaner body 1.

  The cleaner body 1 is provided with a traveling wheel 11 on the side surface and a guide wheel (not shown) on the lower surface, and is used for movement. When cleaning, the operator pulls the hose 2 with the movement. Thus, the cleaner body 1 can be moved. Furthermore, a handle 14 is attached to the upper part of the upper body case 6 so that an operator can carry the cleaner body 1.

  As shown in FIGS. 1 and 3, the cleaner main body 1 forms an outer shell with the upper main body case 6, the dust collecting lid 7, and the lower main body case 8. The dust collecting chamber 12 is formed from the lower main body case 8 and the dust collecting lid 7. The electric blower chamber 13 is formed from the lower main body case 8 and the upper main body case 6.

  In the dust collection chamber 12, the dust collection bag 15 that collects the dust sucked together with the air is detachably mounted. The electric blower chamber 13 is disposed downstream of the dust collection chamber 12. The dust collecting lid 7 is attached to the upper main body case 6 so as to be opened and closed. The dust bag 15 includes a bag member 17 made of a nonwoven fabric such as paper, cloth, or plastic material, and a mouth plate 18 made of cardboard or plastic having an opening 16. The check valve 19 functions to prevent dust accumulated in the bag member 17 from flowing back from the opening 16 provided in the dust collection bag 15 to the connecting portion provided in the hose 2.

  The connecting portion of the hose 2 inserted into the hose connecting port portion 22 and the elastic seal member integrated with the check valve 19 are in close contact with each other. When the check valve 19 is opened, the dust collecting bag 15 A dust-containing air flow flows into the bag member 17 through the opening 16 provided in the bag member 17. Here, the elastic seal member integrated with the check valve 19 is in close contact with the mouth plate 18 provided in the dust collection bag 15 and has an effect of preventing dust from spilling.

  The lower main body case 8 is provided with a central partition wall 20 that partitions the dust collection chamber 12 and the electric blower chamber 13, and the central partition wall 20 transmits the air flow that has passed through the dust collection bag 15. In order to communicate with the electric blower 30, a grid-like circulation port 21 is provided.

  A protective filter (not shown) is provided between the dust bag 15 and the electric blower 30, and a dust removal unit 23 is disposed.

  The dust bag 15 allows a flow of air containing dust to pass therethrough, separates the dust from the air, and collects the dust. When collecting dust, the bag member 17 of the dust bag 15 is gradually clogged. Therefore, the dust removal unit 23 is operated to vibrate the dust collection bag 15 so as to eliminate the clogging dust that clogged the bag member 17 and eliminate the clogging, and the air flow path of the dust collection bag 15 By recovering the above, it is possible to lengthen the replacement period of the dust bag 15.

  With respect to the electric blower 30, the dust collection chamber 12 side is forward, the electric blower chamber 13 side is rearward, the surface of the motor case 9 on which the filter 37 is mounted is up, and the electric blower 30 of the filter 37. When the vacuum cleaner main body 1 is turned upward and the dust collecting chamber 12 is turned upward, the cord reel 24 side is set to the left, and the electric blower side 30 is set to the right.

  The electric blower chamber 13 formed from the upper main body case 6 and the lower main body case 8 includes the cord reel 24 for supplying current, the motor case portion 9 containing the electric blower 30, and the motor case portion 9. The middle case 10 (exhaust flow path member) that forms the exhaust flow path is incorporated.

  As shown in FIG. 4, the motor case unit 9 includes the electric blower 30, the motor case 28 covering the electric blower 30, and a vibration-proof cap 33 (electric blower that supports the rear of the electric blower 30 for vibration prevention). Vibration isolator), anti-vibration rubber 34 (vibration isolator for electric blower) covering the circumference of the fan part 32 of the electric blower 30, the filter 37 attached to the exhaust port of the motor case part 9, the anti-vibration A bell mouth 36 provided between the rubber 34 and the electric blower 30 and having an opening communicating with the air inlet 35 of the electric blower 30, and a spring 29 (motor case) for supporting the motor case portion 9 under the fixing member 40 Anti-vibration material), anti-vibration member 39 (anti-vibration material for motor case) that supports the motor case portion 9 on the lower surface of the anti-vibration rubber 34, and discharge current that discharges on the lower surface of the filter 37. 38 consists of.

  The electric blower 30 is supported by the motor case 28 via the electric motor unit 31 and the vibration isolating cap 33, and further supported by the motor case 28 via the vibration isolating rubber 34. The electric blower 30 as a vibration source is supported by the motor case 28 via the vibration isolation rubber 34 and further supported by the lower main body case 8 via the vibration isolation member 39. Structure is adopted. Therefore, vibration to the motor case 28 is reduced.

  In the motor case 28, a sound absorbing material (not shown) is provided so as to surround the electric motor unit 31, and high-frequency annoying noise from the electric blower 30 is reduced.

  The filter 37 has a substantially square shape, and is fixed to be inclined with respect to a plane formed in the front-rear and left-right directions. Thereby, the dust that could not be removed by the dust collection bag 15 is removed by the filter 37, and clean air is discharged out of the cleaner body 1. By the way, the reason why the filter 37 is inclined with respect to the flow path is to secure a cross-sectional area. By securing the area of the filter 37, pressure loss can be reduced and clogging occurs. It is difficult to maintain the suction power of the vacuum cleaner.

  In addition, the cleaner body 1 includes the discharge electrode 38 in a space formed between the exhaust port of the electric motor unit 31 and the filter 37.

  The discharge electrode 38 has a function of charging dust contained in the exhaust from the exhaust port of the electric motor unit 31, and a brush-like electrode (not shown) and a plate-like electrode (not shown) are predetermined. Arranged at intervals. The discharge electrode 38 is attached via a fixing portion (not shown) provided on the motor case 28. The fixing portion (not shown) is formed in a plate shape with a synthetic resin or the like, and is configured such that the discharge electrode 38 is located near the center below the filter 37. In addition, a sound absorbing plate (not shown) is provided below the discharge electrode 38 so that exhaust gas having a high flow velocity does not directly hit the discharge electrode 38. This sound-absorbing plate (not shown) has air permeability, can reduce the sound of the electric blower 30 while allowing the exhaust of the electric blower 30 to pass through, and can provide a low-noise cleaner.

  As shown in FIG. 5, the motor case portion 9 is housed in the electric blower chamber 13 and is supported by the middle case 10 from above. On the side of the electric blower chamber 13 of the central partition wall 20, an annular rib 25 provided perpendicular to the central partition wall 20 is provided so as to surround the lattice-shaped flow port 21. The motor case portion 9 and the annular rib 25 are supported in close contact via the vibration isolating rubber 34.

  The anti-vibration rubber 34 acts as an anti-vibration material, reduces vibration from the electric blower 30 and transmits it to the central partition wall 20. The anti-vibration rubber 34 also functions as an airtight material, and forms a flow path from the dust collecting chamber 12 to the intake port 35 of the electric blower 30. Therefore, the suction force of the electric blower can be ensured.

  Further, dust that could not be collected by the dust collection bag 15 is accumulated in the flow path from the dust collection chamber 12 to the intake port 35 when the operation is stopped. If the dust-proof rubber 34 and the annular rib 25 are not kept airtight, the accumulated dust may leak out of the cleaner body 1 directly through the electric blower chamber 13 and contaminate the exhaust.

  Again, if the vibration-proof rubber 34 is kept airtight, dust can pass through the filter 37, so that clean air can be discharged outside the cleaner body 1.

  Support ribs 26 that support the motor case 9 are provided at corners formed by the central partition wall 20 and the lower surface of the lower main body case 8.

  The lower body case 8 supports the motor case portion 9 on the support rib 26 via the vibration isolating member 39, and the motor case portion 9 is attached to the lower body case 8 via the spring 29. Anti-vibration support is provided on the boss 27 provided.

  The fixing member 40 extends to the rear side of the motor case portion 9 on a plane including the rotation axis of the electric blower 30 and includes the front-rear and left-right directions, and is disposed two symmetrically about the rotation axis. The spring 29 reduces vibration due to unbalance of the electric blower 30 and propagation of electromagnetic vibration generated in the electric motor unit 31.

  The boss 27 facilitates support of the spring 29 and positioning in the front-rear and left-right directions, so that the assemblability is improved.

  In this embodiment, the boss 27 is used for the connection between the motor case 9 and the spring 29 and the connection between the spring 29 and the lower main body case 8, but a metal fitting is installed and fixed by welding or the like. May be.

  As shown in FIG. 6, the anti-vibration rubber 34 and the anti-vibration member 39 are arranged in close contact with each other, and the anti-vibration member 39 has a shape that follows the curvature of the anti-vibration rubber 34. In the present embodiment, five support ribs 26 extending from the lower main body case 8 are arranged in order to evenly distribute the load applied to the support ribs 26 by equalizing the distance between the vibration isolating rubber 34 and the support ribs 26. I am doing. This is to prevent the vibration isolating member 39 from being used in the plastic region due to the concentrated load and large deformation.

  Further, since the vibration isolation member 39 is supported by the support rib 26, the apparent elastic coefficient can be reduced and the vibration isolation effect can be enhanced.

  Further, the support ribs 26 from the central partition wall 20 are disposed symmetrically with respect to the front and rear and up and down surfaces including the rotation shaft of the electric blower 30. This is because the installation of the electric blower 30 is taken into consideration to facilitate the support.

  In the present embodiment, the five support ribs 26 are evenly arranged. However, five or more support ribs may be used as long as they are symmetrical with respect to the front and back and up and down directions including the rotation axis on the same plane. Absent.

  The middle case 10 is fixed to the lower main body case 8.

  As shown in FIG. 4, an anti-vibration rubber packing 41 [airtight anti-vibration material for exhaust air passage (anti-vibration material for motor case)] is shaped to cover the edge 42 of the filter 37, and the middle The case 10 supports the motor case portion 9 with vibration isolation via the vibration isolation rubber packing 41. As a result, the positioning and assembling of the motor case portion 9 are improved, and the motor case portion 9 is prevented from being displaced by an impact force such as a drop or a collision.

  The middle case 10 forms a flow path with the motor case portion 9, and the flow path has no irregularities. Therefore, since the air flow inside the flow path is smooth, loss can be reduced and noise due to fluid sound can be reduced.

  Further, the air flow path formed by the motor case portion 9 and the middle case 10 is kept airtight. Therefore, the noise from the electric blower 30 can be propagated without leaking from the motor case portion 9 to the middle case 10. The opening of the motor case portion 9 and the flow path in the middle case 10 are shaped to be deflected by approximately 90 degrees, have a property like a right-angled bending duct used for the purpose of noise reduction, and from the electric blower 30 Noise can be reduced.

  Further, since the middle case 10 can take any shape, the position of the opening 43 of the flow path communicating with the motor case portion 9 of the middle case 10 is set to an arbitrary position of the electric blower chamber 13. Can do. Therefore, the electric blower chamber 13 can form a silencer.

  In this embodiment, the bent portion of the middle case 10 is formed of a cavity, but guide vanes may be installed. By installing the guide vanes, peeling of the bent portion is suppressed and loss is reduced, so that an improvement in work rate can be expected. Further, by installing a sound absorbing material and making it a sound absorbing duct, it is possible to have both the effect of a right-angled bending duct and the effect of a sound absorbing duct, and the high frequency sound from the electric blower 30 and the electric blower 30 and the motor case 28. Turbulent sound generated between the two can be reduced.

  The supporting operation of the electric blower chamber 13 will be described.

  The vacuum cleaner body 1 sucks air by rotation of the impeller of the fan part 32, and the air flow 101 that has passed through the dust bag 15 passes through the electric motor part 31 to be cooled, and the motor case 28, The air is exhausted out of the cleaner body 1 through the filter 37, the middle case 10, and the cleaner body 1.

  The filter 37 separates dust and air that could not be collected by the dust bag 15 from the air.

  When the rotating body of the electric blower 30 is unbalanced, the electric blower 30 generates vibration. The vibration from the electric blower 30 propagates to the motor case portion 9 and the electric blower chamber 13.

  The vibration caused by the unbalance of the rotating body of the electric blower 30 includes one in which the unbalance of the blower and the unbalance of the electric motor are synchronized with each other. Synchronous and asynchronous vibrations can be reduced by sandwiching the center of gravity instead of the center of gravity of the electric blower 30, supporting the motor case 9 symmetrically with respect to the rotation axis, and supporting the motor case portion 9.

  When dust collects in the dust collection bag 15, the degree of vacuum of the flow path connecting the intake port 35 of the electric blower 30 and the dust collection chamber 12 is increased, and the motor case portion 9 is forced forward. However, the movement of the motor case portion 9 is prevented by the shearing force of the spring 29 and the drag of the vibration-proof rubber packing 41.

  By preventing the motor case portion 9 from moving, the forward force applied to the electric blower 30 is reduced. However, the force by the suction force is applied to the motor case portion 9 in the forward direction and the gravity is applied to the downward direction. The direction of the resultant force faces the direction from the electric blower 30 toward the support rib 26. For this reason, since the vibration isolating member 39 thickens the vibration isolating material in the direction of the resultant force, the vibration isolating effect can be enhanced.

  In addition, when the power is supplied, the electric blower 30 receives a force in the rotation direction due to the torque at the time of starting rotation. The electric blower 30 transmits a rotational force to the motor case portion 9, and the motor case portion 9 is rotated in the rotational direction by the anti-vibration rubber packing 41 and two springs 29 arranged symmetrically with respect to the rotational axis. Support power.

  Moreover, the said vacuum cleaner main body 1 may collide with furniture, a roll, and fall. In such a case, it is necessary to support the rotating shaft of the electric blower so as not to move.

  The electric blower 30 is supported by the anti-vibration rubber 34, the anti-vibration cap 33, the anti-vibration rubber packing 41, the anti-vibration member 39, and the spring 29 in the vertical direction and the rotational direction around the axis that forms the left-right direction. is doing.

  The electric blower 30 includes the anti-vibration rubber 34, the anti-vibration cap 33, the anti-vibration rubber packing 41, the front-rear direction, the left-right direction, the rotation direction around the rotation axis, and the rotation direction around the vertical axis. The spring 29 is supported.

  For this reason, since the rotational motion is restricted in the vertical and horizontal directions and the front-rear direction, the vibration-proof rubber 34 and the annular rib 25 are kept airtight, and the vibration-proofing effect of each member is also ensured.

  The motor case portion 9 configured to support the electric blower 30 and the motor case 28 in an anti-vibration manner is supported in the electric blower chamber 13 in an anti-vibration direction from above and below, so that vibration from the electric blower 30 is It reduces in the process transmitted to the said motor case part 9 and the said electric blower chamber 13, and reduces the vibration of the said vacuum cleaner main body 1 outer wall.

  The spring 29 and the anti-vibration rubber packing 41 generate a force in a direction to suppress the movement of the motor case portion 9 to the front side, and the anti-vibration rubber 34 is excessively deformed during suction, and deviates from the elastic region. To prevent it. The anti-vibration rubber 34 prevents the vibration transmitted to the annular rib 25 from becoming large, and the anti-vibration rubber 34 and the annular rib 25 are separated by the movement of the motor case portion 9 to reduce the suction force. Dust that could not be collected by the dust bag 15 is prevented from leaking.

  In addition, there is a possibility that the electric blower 30, the motor case portion 9, each vibration isolating material, and packing are displaced due to the force accompanying the starting rotational torque immediately after the operation of the vacuum cleaner. By supporting the anti-vibration rubber packing 41 and the spring 29, there is no fear that the motor case portion 9 is displaced, and there is no concern that the suction force is reduced or abnormal noise is generated.

  Furthermore, the electric blower 30 has a low vibration frequency at start-up and gradually becomes a high frequency. Use of a non-linear spring having a large elastic coefficient when the displacement is large and a small elastic coefficient when the displacement is small increases the effect of preventing vibrations having a high frequency and a large vibration level.

  Further, the spring 29 is supported by a plane which includes a rotation axis on the same plane and which forms the front and rear and left and right directions. The boss 27 is elastically supported in the front and rear direction, and the anti-vibration rubber packing 41 is used to support the left and right directions. Therefore, it is effective not only for synchronous and asynchronous vibrations but also for vibrations of the electric blower 30 accompanied by air pulsation, and to provide a low-noise vacuum cleaner. Can do.

  That is, since the spring 29 is disposed on a plane that crosses the longitudinal direction of the rotation axis of the electric blower 30, it effectively acts to prevent the force in the rotation direction accompanying the rotation of the electric blower.

  By using the vacuum cleaner having the above-described configuration, it is possible to provide a low-noise cleaner while maintaining dust collection performance.
