The second annular rib 43 of the lower case 40 and the second annular rib 34 of the display case 31 are joined via a seal member S1.

[0029] A sound generating mechanism is provided, and this sound generating mechanism is arranged to abut on the abutting portion 40A provided around the cylindrical portion 41 of the lower case 40 and the abutting portion described later. And a flange 54B of the clamp member 54. When the flange 54B of the cap member 54 collides with the abutting portion 40A of the lower case 40, a sound is generated.

[0030] The partition wall 50 includes a soft resin diaphragm portion 53 formed in a substantially circular shape when viewed from above, and a cap member 54 attached to a hole 53A provided in the center portion of the diaphragm portion 53. ing.

[0031] A flange 53F having an H-shaped cross section is formed on the outer peripheral edge of the diaphragm 53, and this flange 53F is joined to the first annular rib 33 of the display case 31 and the first annular rib 42 of the lower case 40. Yes. [0032] The cap member 54 has a cylindrical cap 54A and a flange 54B formed at the lower portion of the cap 54A, and the peripheral edge of the flange 54B is integrated with the edge of the hole 53A of the diaphragm 53. It is joined. The cap 54A is fitted into the cylindrical portion 41 of the lower case 40, and the cap 54A is movable along the axial direction of the cylindrical portion 41. Further, the cap 54 A can enter the cylindrical portion 32 of the display case 31. A coil spring SP is attached to the cylindrical portion 32 of the display case 31 and the cap 54A of the partition wall 50, and the partition wall 50 is urged toward the atmospheric pressure chamber 52.

The partition 50, the display case 31, and the first annular rib 33 define a negative pressure chamber 51, and the partition 50, the lower case 40, and the first annular rib 42 define an atmospheric pressure chamber 52.

The negative pressure chamber 51 is communicated with the dust collection chamber 12 through the long hole 33 A of the first annular rib 33 of the display case 31 and the hole 45 of the lower case 40. The atmospheric pressure chamber 52 is communicated with the atmosphere through the hole 42 a of the first annular rib 42 of the lower case 40 and the hole 36 of the display case 31.

[0035] The top surface of the top plate portion 54a of the cap 54A is colored, for example, green, and the bottom surface of the top plate portion 54a extends downward and has a shaft 5 6 that passes through the inside of the cylindrical portion 41 of the lower case 40. The shaft 56 is integrally attached, and the shaft 56 moves integrally with the movement of the cap 54A in the axial direction. A cap body 57 and a pressure member 60 shown in FIG. 6 are attached to the lower part of the shaft 56, and the cap body 57 and the pressure member 60 move in the axial direction together with the shaft 56.

The cap member 57 is formed with a pair of opposed recesses 57 A and 57 A, and a C ring 58 is attached to the outer peripheral surface of the cap member 57. The arms 47 and 47 of the lower case 40 are inserted into the space surrounded by the recesses 57A and 57A and the C ring 58. A holding mechanism that holds the partition wall 50 in the displaced position until the negative pressure chamber 51 reaches a predetermined pressure is provided. This holding mechanism has projections 47a, 47a of arm portions 47, 47 and a C ring 58 with which these projections engage. When the arm portions 47 and 47 are inserted into the space surrounded by the recesses 57A and 57A and the C ring 58, the projections 47a and 47a of the arm portions 47 and 47 engage with the C ring 58 and the negative pressure chamber 51 is predetermined. Hold the septum 50 in the displaced position until pressure is reached (see Figure 8).

As shown in FIG. 6, the pressurizing member 60 has a flat substrate 61 and a plurality of hitting ribs 62 provided on the substrate 61.

[0038] The cover case 70 is attached to the back surface of the lid case 21 as shown in FIG. Covers substrate 61 (see Figure 6). In addition, a plurality of slit-shaped holes 71 are formed in the cover case 70, and the hitting ribs 62 of the pressure member 60 project downwardly through these holes 71 as shown in FIG.

[0039] Next, the operation of the electric vacuum cleaner configured as described above will be described.

[0040] When the electric blower 13 is stopped, the negative pressure chamber 51 of the dust removing device 30 shown in Fig. 3 is at atmospheric pressure, and the partition wall 50 is positioned as shown in Fig. 3 by the biasing force of the spring SP. Is located. In this state, since the top plate portion 54a of the cap 54A is separated from the display case 31, it is difficult to see the top plate portion 54a of the cap 54A through the translucent display case 31.

In addition, the hitting rib 62 of the pressure member 60 protrudes from the hole 71 of the cover case 70 as shown in FIG. 3 and FIG.

[0042] In this state, when the electric blower 13 is driven by the operation of the operation switch Sa of the hand operation tube 17, the dust collecting chamber 12 becomes negative pressure. This negative pressure acts on the suction chamber of the suction port body 20 through the dust collection hose 15, the hand control pipe 17, and the extension pipe 18, and dust and dirt on the surface to be cleaned are removed from the suction opening located on the bottom surface of the suction port body 20. Air is sucked into the dust collecting chamber 12 of the vacuum cleaner body 11 through the extension pipe 18, the hand control pipe 17, and the dust collecting hose 18.

[0043] The dust sucked into the dust collecting chamber 12 is collected by the dust collecting filter 19 mounted in the dust collecting chamber 12, and the air is sucked into the electric blower 13 and then the view of the cleaner body 11 Don't show me!

On the other hand, when the dust collection chamber 12 becomes negative pressure by driving the electric blower 13, the negative pressure chamber 51 of the dust removing device 30 shown in FIG. 3 becomes negative pressure. Due to the negative pressure in the negative pressure chamber 51, the partition wall 50 is displaced against the biasing force of the spring SP upward as shown in FIG. Due to the displacement of the partition wall 50, the cap member 54 of the partition wall 50 moves upward so that the cap 54A enters the cylindrical portion 32 of the display case 31, and the top plate portion 54a of the cap 54A approaches the display case 31.

[0045] Due to this proximity, the top plate portion 54a of the cap 54A can be clearly seen through the translucent display case 31, and the user has entered the preparatory stage where the dust removing device 30 hits the dust collecting filter 19. Can be recognized. Further, the shaft 56 of the cap member 54 moves upward integrally with the cap member 54, and the pressure member 60 and the cap body 57 move upward as the shaft 56 moves. Due to the upward movement of the cap body 57, as shown in FIG. 8, the arm portions 47, 47 of the lower case 40 enter the recesses 57A, 57A of the cap body 57, and the protrusions 47a of the arm portions 47, 47 , 4 7a engages with C-ring 58. As a result, the cap member 54 is held at the position (displacement position) shown in FIG.

[0047] On the other hand, the pressing member 60 moves upward by the upward movement of the shaft 56 of the cap member 54, so that the hitting rib 62 of the moved pressing member 60 has a cover case as shown in FIG. Retract from hole 71 of the screw 70 and enter the cover case 70. As a result, the dust collection filter 19 comes into contact with the lower surface of the cover case 70 as shown by the chain line in FIG.

[0048] When the drive of the electric blower 13 is stopped, the pressure in the dust collection chamber 12 increases with the stop operation of the electric blower 13, and finally becomes atmospheric pressure. At this time, the negative pressure chamber 51 of the dust removing device 30 also rises with the pressure of the dust collecting chamber 12, and the pressure difference between the atmospheric pressure chamber 52 and the negative pressure chamber 51 of the dust removing device 30 decreases. When the force that pushes up the partition wall 50 by this reduction in pressure difference becomes smaller than the biasing force of the spring SP, the partition wall 50 is biased downward.

[0049] When the downward urging force applied to the partition wall 50 exceeds a predetermined value, that is, when the negative pressure chamber 51 reaches a predetermined pressure, the projections 47a, 47a of the arm rods 47, 47 of the lower rod case 40, the ring 58 force, etc. The shaft 56 and the pressure member 60 move downward together with the partition wall 50, and the hitting rib 62 of the pressure member 60 protrudes downward from the hole 71 of the cover case 70 to the lower surface of the cover case 70. Tap the abutting dust collection filter 19. In this case, the partition 50 is in the state shown in FIG.

[0050] Thereby, dust adhering to the dust collection filter 19 can be surely dropped, and clogging of the dust collection filter 19 is reduced. In addition, when the hitting rib 62 of the pressure member 60 presses the dust collection filter 19, since the drive of the electric blower 13 has already been stopped, the dropped dust may adhere to the dust collection filter 19 again. Dust adhering to the dust collecting filter 19 can be efficiently removed.

[0051] Further, since the pressure member 60 is capable of collecting pressure from above the dust collection filter 19, the dust collection filter The dust attached to the upper part of the filter 19 can be dropped more, and the dust whose force has been reduced will not adhere again to the upper part of the dust collecting filter 19. Each time the electric blower 13 is stopped, the pressure member 60 applies pressure to the dust collection filter 19 from above, so that the dust contains moisture! Can be prevented. Therefore, the air permeability of the dust collection filter 19 can be reliably ensured until the dust collection filter 19 is saturated with dust.

As shown in FIG. 3, the flange 54B of the cap member 54 of the partition wall 50 collides with the contact portion 40A of the lower case 40 to generate sound. The generation of this sound makes it possible to recognize that the hitting rib 62 of the pressure member 60 presses the dust collection filter 19.

[0053] Since the electric blower 13 is stopped (turned off) many times during cleaning, the dust collection filter 19 is pressed or hit many times by the striking rib 62 of the caloric pressure member 60, and the dust collection filter 19 Dust adhering to the filter 19 can be sufficiently removed, so that the dust collection filter can be almost free of dust, and clogging of the dust collection filter 19 can be reliably reduced. I'll do it.

[0054] In the above embodiment, the dust removing device 30 is configured to drop the dust adhering to the dust collection filter 19. However, the present invention is not limited to this. For example, the photocatalytic type provided in the dust collection chamber 12 is used. Dust adhering to the dust container or the like may be dropped, or dust adhering to the secondary dust container provided downstream of the dust collection filter 19 may be dropped.

Further, the diaphragm portion 53 of the partition wall 50 of the above embodiment is formed of an elastic member, and when the partition wall 50 is displaced to the position shown in FIG. 8, the partition wall 50 returns to the original position shown in FIG. If an urging force is applied to the diaphragm 53, the spring SP becomes unnecessary. In this case, when the partition wall 50 is displaced to the position shown in FIG. 8, the diaphragm 53 is brought into contact with the back surface of the spherical display case 31, and the diaphragm 53 is deformed so that it does not return to the original position. Let's prevent it.

FIG. 9 conceptually shows the configuration of the dust removing device 100 of the second embodiment. In FIG. 9, reference numeral 101 denotes a partition wall provided in the lid case 21, and this partition wall 101 is displaced as indicated by a chain line when the dust collection chamber 12 has a negative pressure. The partition wall 101 is provided with a rod 102 extending downward so that the partition wall 101 moves downward as indicated by a chain line in accordance with the displacement of the partition wall 101. It has become.

[0057] Reference numeral 103 denotes a rotating member that rotates about the shaft 104. The rotating member 103 and the rod 102 constitute a pressurizing member in the first embodiment. A hitting portion 105 for hitting the dust collecting filter 19 is formed at the tip of the rotating member 103. Further, the lower portion of the rod 102 is in contact with the rear portion of the rotating member 103, and the rotating member 103 is urged counterclockwise by a spring (not shown). In the second embodiment, the driving device for driving the rotating member includes a direction mechanism for moving the pressing member 103 in a direction different from the displacement direction when the partition wall 101 is displaced. In this second embodiment, when the partition wall 101 is displaced upward as indicated by the solid line, the rotating member 103 rotates so as to strike the dust collecting filter via the rod 102 in this second embodiment. As indicated by a chain line, when the member is displaced downward, the rotating member 103 is configured to rotate away from the dust collection filter 19 via the rod 102.

[0058] When the dust collecting chamber 12 becomes negative pressure by driving the electric blower 13 (see Fig. 1), the partition wall 101 is displaced to the chain line position, and the rotating member 103 is rotated to the chain line position. The rotating member 103 is held at the chain line position by the direction change. Next, when the driving of the electric blower 13 is stopped, the pressure in the dust collecting chamber 12 increases, so that the rotating member 103 is rotated counterclockwise by the biasing force of the spring, and the hitting portion 105 is Tap the dust collection filter 19 to remove dust adhering to the dust collection filter 19.

[0059] According to the second embodiment, since the hitting portion 105 is moved in the direction opposite to the displacement direction of the partition wall 101 by the rotating member 103, the dust collection filter 19 can be hit with a simple configuration. The

[0060] In the second embodiment, using a force gear or the like that moves the hitting portion 105 in the direction opposite to the displacement direction of the partition wall 101 by the rotating member 103, the hitting portion in the direction opposite to the displacement direction of the partition wall 101 is used. 105 may be moved.

[0061] Although various embodiments as described above have been described, the present invention is not limited to these embodiments, and various changes and modifications can be made to these embodiments.
