Embodiment 1
1 and 2 are sectional views showing a vacuum cleaner according to Embodiment 1 of the present invention, and FIG. 1 shows that an outer lid that opens and closes an opening of a dust collection chamber (attachment / detachment opening of a dust collection case) is opened. FIG. 2 shows a state where the outer lid is closed and locked to the main body case. 1 and 2, a main body case 1 includes a suction port 2, a dust collection chamber 3 that communicates with the suction port 2, a rotatable outer lid 4 that opens and closes the opening of the dust collection chamber 3, and an interior that communicates with the dust collection chamber 3. An exhaust fan 5, an electric blower chamber 6 that communicates with the internal exhaust vent 5, and an external exhaust port 7 that communicates with the electric blower chamber 6 are provided. A dust collection case 9 is detachably disposed in the dust collection chamber 3, and an electric blower 10 is disposed in the electric blower chamber 6. In the lower part of the main body case 1, rotatable wheels 11 </ b> A and 11 </ b> B are provided, and a hose 12 equipped with a suction tool is connected to the suction port 2 of the main body case 1.

The dust collection case 9 has a connection port 91 communicating with the suction port 2 on its front wall and a ventilation surface (including a filter) 92 communicating with the internal exhaust port 5 and the electric blower chamber 7 on its rear wall. . Note that the rear wall of the dust collecting case 9 may be simply opened.
The dust collection case 9 may be provided with a dust collection bag (not shown here) in a detachable manner so as to collect the dust in the dust collection bag. Alternatively, the dust collection case 9 has a rear surface as a ventilation surface 92 to collect dust. You may make it collect in the case 9 directly.
A rotatable handle (hereinafter referred to as a “rotating handle 95”) that is used for attaching and detaching the dust collecting case 9 is provided above the dust collecting case 9.

On the bottom surface of the dust collection chamber 3, a dust collection case urging mechanism is provided that includes a coil spring 14 and a base 15 that covers the tip of the coil spring 14 and urges the dust collection case 9 upward. The coil spring 14 is preferably provided at a position closer to the internal exhaust port 5 side than the center of the bottom surface of the dust collection chamber 3. This is because the dust collection is accumulated in the dust collection case 9 from the side of the internal exhaust port 5, and usually the center of gravity of the dust collection case 9 is in that portion.
Note that the dust collection case urging mechanism may be configured by using another elastic body such as another spring or rubber instead of the coil spring 14.
The upper opening of the dust collection chamber 3 can be opened and closed by an outer lid 4 that rotates in the direction of arrow A about a rotation center axis (not shown here).

Around the suction port 2 of the main body case 1, a packing 13 is provided to ensure a sealing property between the connection port 91 of the dust collection case 9 and the main body case 1 when the dust collection case 9 is in the use position. .
A packing 93 is provided on the rear outer periphery of the dust collecting case 9 to ensure a sealing property with the main body case 1 when the dust collecting case 9 is in the use position.

On the suction port 2 side of the main body case 1, a holding member 17 for pressing and holding the dust collection case 9 pushed upward by the coil spring 14 in the dust collection chamber 3 is provided. The convex portion 94 formed in the case 9 is locked, and the dust collection case 9 is pressed and held at a predetermined position (use position) in the dust collection chamber 3. Therefore, the holding member 17 and the convex portion 94 of the dust collection case 9 constitute a latch mechanism for the dust collection case 9.
The holding member 17 is configured to be rotatable about a shaft 18 and is constantly urged by a spring 19 in a direction opposite to the arrow B direction. The holding member 17 includes a hooking claw 17a formed at the end of a slope whose thickness increases in the downward direction, and a convex portion 94 is locked to the hooking claw 17a. When the dust collecting case 9 is pushed into the dust collecting chamber 3, the convex portion 94 slides on the slope leading to the hooking claw 17a to reach the hooking claw 17a, where it is locked to the hooking claw 17a. The locking between the convex portion 94 and the hooking claw 17a can be removed by rotating the holding member 17 in the arrow B direction.

  Next, the operation of the electric vacuum cleaner will be described. The dust sucked from the hose 12 by the suction of the electric blower 10 is collected in the dust collecting case 9 via the suction port 2 and the connection port 91, and only the exhaust gas passes through the internal exhaust port 5 and the electric blower chamber 6. Then, it is discharged outside through the external exhaust port 7. When the dust collecting case 9 is taken out from the dust collecting chamber 3 to dispose of dust in the dust collecting case 9, the outer cover 4 locked by the main body case 1 and closed is opened. Take out. When the outer lid 4 is fully opened, the upper part of the dust collecting case 9 protrudes from the dust collecting chamber 3 due to the upward biasing of the coil spring 14, so that the rotation handle 95 provided on the upper or upper surface of the dust collecting case 9. Thus, the dust collecting case 9 can be easily removed from the main body case 1.

Embodiment 2
FIG. 3 is a cross-sectional view of the electric vacuum cleaner according to Embodiment 2 of the present invention, and shows a state where the outer lid 4 is closed and locked to the main body case 1. Here, when the outer lid 4 is closed, a latch release rib 42 that releases the locking between the holding member 17 and the convex portion 94 of the dust collecting case 9 is provided integrally with the outer lid 4 inside the outer lid 4. ing.
That is, the dust collection case 9 is held at a predetermined position (for example, a use position) in the dust collection chamber 3 by the engagement between the holding member 17 and the convex portion 94 of the dust collection case 9. Thereafter, when the closing operation of the outer lid 4 that closes the opening of the dust collecting chamber 3 is performed, the latch release rib 42 contacts the holding member 17 near the end point of the closing operation and rotates it in the direction of arrow C. The latching claw 17a of the holding member 17 and the projection 94 are unlocked. The latch release rib 42 is formed in such a manner as to maintain a state in which the engagement between the hooking claw 17a and the convex portion 94 is released while the outer lid 4 is in the closed position.
In addition, a pressing rib 43 integral with the outer lid 4 is provided inside the outer lid 4, and when the outer lid 4 is closed, the pressing rib 43 is brought into contact with the upper portion of the dust collecting case 9. Thus, the dust collection case 9 is held at a predetermined position (use position) in the dust collection chamber 3.

Next, the operation of the outer lid 4 and the dust collecting case 9 in the second embodiment will be described. When the dust collection case 9 is pushed into the dust collection chamber 3, the convex portion 94 of the dust collection case 9 is locked to the hooking claw 17 a of the holding member 17, and the dust collection case 9 is brought into a predetermined position in the dust collection chamber 3. Retained. Thereafter, when the outer lid 4 is further closed, the latch release rib 42 releases the engagement between the hooking claw 17a and the convex portion 94. However, when the outer lid 4 is completely closed and locked to the main body case 1, the dust collecting case 9 is pressed and held at a predetermined position in the dust collecting chamber 3 by the holding rib 43 instead of the holding member 17. Will be.
Since the dust collection case 9 is housed in the main body case 1 in such a state, when the dust collection case 9 is taken out, the dust collection case 9 becomes free by simply opening the outer lid 4. 9 is automatically pushed upward by the lower coil spring 14. As a result, when the dust collection case 9 is taken out, the dust collection case 9 can be easily taken out from the main body case 1 without particularly performing an unlocking operation with the holding member 17.

Embodiment 3
FIG. 4 is a cross-sectional view showing a vacuum cleaner according to Embodiment 3 of the present invention, in which the dust collection case 9 placed in alignment with the opening of the dust collection chamber 3 is placed at a predetermined position (use position). It explains the pushing. Here, the outer lid 4 is provided with push-in ribs 44 formed integrally therewith. The pushing rib 44 functions to push the dust collecting case 9 into a predetermined position of the dust collecting chamber 3 when the outer lid 4 is closed. That is, when the dust collection case 9 is attached to the dust collection chamber 3, if the dust collection case 9 is only positioned in the horizontal direction and set roughly, the dust collection case 9 floats upward by the lower coil spring 14. It becomes the state. Thereafter, when the operation of closing the outer lid 4 is performed, the pushing rib 44 acts on the dust collection case 9 corresponding to the closing operation of the outer lid 4, and the action of pushing the dust collection case 9 into a predetermined position in the dust collection chamber 3. Fulfill. Furthermore, when the outer lid 4 is in the closed state, it also serves to hold the dust collection case 9 in a predetermined position.

Therefore, when attaching the dust collecting case 9 to the dust collecting chamber 3, it is not necessary to push the dust collecting case 9 by hand. If only the horizontal positioning is performed, the outer lid 4 is closed and the dust collecting chamber 3 is closed. Since it is pushed to a predetermined position, the dust collecting case 9 can be attached to the main body case 1 more easily.
It is preferable that the push-in rib 44 that performs the above-described action is formed inside the outer lid 4 so as to correspond to the rear part of the dust-collection case 9 having the largest push-in friction of the dust-collection case 9. .

Embodiment 4
FIG. 5 is a cross-sectional view of the electric vacuum cleaner according to Embodiment 4 of the present invention, and shows a state where the outer lid 4 is closed and locked to the main body case 1. Here, the movable gap of the dust collection case 9 in a predetermined region in the dust collection chamber 3 (a certain range allowed as the use position of the dust collection case 9) will be described.
FIG. 5 shows a state in which the center of the suction port 2 of the main body case 1 and the center of the connection port 91 of the dust collecting case 9 coincide. In such a state, the clearance between the convex portion 94 of the dust collection case 9 and the hooking claw 17a is defined as C, and the clearance between the bottom surface of the dust collection chamber 3 and the pedestal 15 that covers the upper end of the coil spring 14 is defined as D. These gaps C and D indicate the movable gap of the dust collection case 9 at the use position in the dust collection chamber 3.

On the other hand, the inner diameter H of the suction port 2 portion of the main body case 1 is provided smaller than the inner diameter G of the connection port 91 of the dust collecting case 9. In the present embodiment, the relationship among the gap C, the gap D, the inner diameter G, and the inner diameter H is set as follows.
C ≦ (GH) / 2
D ≦ (GH) / 2
G> H

Next, the operation and effect of the electric vacuum cleaner having the movable gap will be described. In many cases, the vacuum cleaner is used by moving it around. When the vacuum cleaner gets over the step on the floor surface, the vacuum cleaner vibrates in the vertical direction. Inside the dust collection chamber 3, the dust collection case 9 is provided by the movable gaps C and D and the coil spring 14 described above. Is transmitted to a dust bag or a ventilation surface (which may include a filter) 92 that is clogged with dust. By this transmitted vibration, clogging of the dust collection bag and the ventilation surface 92 is eliminated, and more collection performance can be ensured.
In addition, due to the relationship between the gaps C and D and the inner diameters G and H, even if the dust collection case 9 is moved up and down, the connection port 91 of the dust collection case 9 and the suction port 2 of the main body case 1 are not misaligned. Therefore, the dust sucked from the hose 12 is surely guided into the dust collecting case 9 without spilling into the dust collecting chamber 3.

Embodiment 5
FIG. 6 is a sectional view showing a vacuum cleaner according to Embodiment 5 of the present invention, and shows a state where the outer lid 4 is opened. Here, a protrusion 96 protruding from the side surface of the case is provided on the side surface of the dust collecting case 9. Further, the main body case 1 is provided with a packing 20 for enhancing the suction effect of the electric blower 3 by sealing between the dust collection chamber 3 and the outer lid 4 over the entire circumference. The dust collecting case 9 is disposed in a relationship in which the projecting portions 96 and the packing 20 interfere with each other or be locked at or near the urging end position where the dust collecting case 9 is pushed upward by the action of the coil spring 14. That is, the protrusion 96 and the packing 20 of the dust collection case 9 constitute a dust collection case locking mechanism that defines the amount of protrusion of the dust collection case 9 from the dust collection chamber 3.

The operation and effect of the electric vacuum cleaner according to Embodiment 5 configured as described above will be described.
When the closed outer lid 4 is opened, the dust collecting case 9 is pushed out of the dust collecting chamber 3 by the biasing of the coil spring 14 below. Therefore, when used or stored in a vertically placed state where the open surface of the dust collection chamber 3 is a vertical surface, the dust collection case 9 is excessively moved when the outer lid 4 is opened by the bias of the coil spring 14. There is a possibility that the dust that has fallen from 1 and collected in the dust collecting case 9 will be scattered on the floor surface. However, in the vacuum cleaner of this configuration, the dust collecting case 9 is dropped from the dust collecting chamber 3 because the packing 20 and the protrusion 96 provided on the side surface of the dust collecting case 9 interfere with each other during or at the end of the drawing operation. Can be prevented.
In addition, it is preferable that the projection 96 constituting the dust collection case locking mechanism is provided on the rear surface of the dust collection case 9. This is because in the state where the vacuum cleaner is set up, the dust collecting case 9 comes to the rear side of the main body due to gravity, so that the interference with the packing 20 is executed more effectively.

Embodiment 6
7 and 8 are cross-sectional views showing the inside of the electric vacuum cleaner according to the sixth embodiment. FIG. 7 shows a state in which the outer lid 4 is closed and locked to the main body case 1, and FIG. It is a figure showing the middle of the lid | cover 4 being opened.
In the sixth embodiment, the engagement between the inner side of the outer lid 4 and the upper part of the dust collecting case 9 is in a range from the closed state of the outer lid 4 to the predetermined opening degree of the outer lid 4. When the outer lid 4 is opened, the engaging pieces 47 of the outer lid 4 act on the engaging pieces 97 of the dust collecting case 9 to open the dust collecting case 9 toward the suction port 2. It is constructed so that the engaging pieces 47 and 97 are separated from each other after being lifted while being pressed. The engaging piece 47 is formed integrally with the outer lid 4, and the engaging piece 97 is formed integrally with the dust collecting case 9.
The reason for providing this is that while the electric blower 10 is used to suck dust and the like from the suction port 2, the rear surface of the dust collection case 9 forms the periphery of the internal exhaust port 5 of the main body case 1. This is for coping with the fact that the dust collection case 9 becomes difficult to be removed from the dust collection chamber 3.

  Next, a method for taking out the dust collecting case 9 in the electric vacuum cleaner according to the sixth embodiment will be described. First, in order to open the outer lid 4 that has closed the opening of the dust collection chamber 3, a finger is inserted through the opening 50 formed in the main body case 1 at a portion corresponding to the tip of the outer lid 4, and the outer lid 4 is opened. 4 is released and the outer lid 4 is lifted. As a result, the outer lid 4 starts to move around its rotation center axis 100. At this time, the movable locus of the engaging piece 47 of the outer lid 4 below the rotating shaft 100 once goes upward while facing the suction port 2 side, and the engaging portion between the engaging piece 47 and the engaging piece 97 rotates. If it becomes a horizontal position (same height position) with the axis | shaft 100, it will go further upwards, this time toward the electric blower chamber 6 side. Along with such a movement locus of the engagement piece 47 of the outer lid 4, the locus of the engagement piece 97 of the dust collecting case 9 engaged with the engagement piece 47 is also upward while once moving toward the suction port 2 side. When the engaging portion between the engagement piece 47 and the engagement piece 97 is in a horizontal position with the rotation center shaft 100, the engagement between them is released.

  As described above, along with the locus of the engaging portion of the engaging piece 47 and the engaging piece 97, the entire dust collecting case 9 also rises upward while once moving toward the suction port 2 side. As a result, the dust collection case 9 that is in close contact with the isolation wall 31 on the back of the dust collection chamber that forms the periphery of the internal exhaust port 5 of the main body case 1 is released from the close contact with the isolation wall 31. When the engaging portion of the engaging piece 47 and the engaging piece 97 is in a horizontal position with the rotation center shaft 100, the engagement between them is released and the dust collecting case 9 falls into the dust collecting chamber 3, but the separating wall 31 Therefore, the dust collection case 9 can be easily taken out from the dust collection chamber 3.

Embodiment 7
Next, a vacuum cleaner according to Embodiment 7 of the present invention will be described with reference to FIGS. In the seventh embodiment, the front end of the outer lid 4 that opens and closes the opening of the dust collection chamber 3 engages with a flange 51 provided in a notch (hereinafter referred to as an opening 50) at the front end of the main body case 1 A buckle 48 for holding the lid 4 in a closed state is provided. The buckle 48 has an L-shape that can rotate around a central shaft 48 a, and one end of the buckle 48 can be engaged with the flange 51 of the main body case 1, and the other end of the buckle 48 The portion can be brought into contact with an unlocking button 49 provided on the outer lid 4 so as to be pressed from the outside of the outer lid 4. The lock release button 49 is supported by an elastic body such as a spring so as to be freely returned. When the lock release button 49 is pressed, the bottom of the lock release button 49 is engaged with the flange 51 of the main body case 1. It acts on the buckle 48 and acts to remove it from the collar 51. As a result, the closed outer lid 4 is opened, and the state shifts from FIG. 7 to FIG.

  In the seventh embodiment, a finger can be inserted from the opening 50 between the distal end portion of the outer lid 4 and the main body case 1, and the buckle 48 can be operated by the finger. Thus, the buckle 48 can be removed from the collar 51 and the outer lid 4 can be opened by using the unlocking button 49 or by directly operating with a finger.

  As shown in FIG. 9, an arm 40 that supports the outer lid 4 is attached to the rotation center shaft 100 of the outer lid 4. The rotation center shaft 100 of the outer lid 4 is provided with a spring 101 as a repulsive force generator that constantly biases the outer lid 4 in the opening direction. In addition, when the lock release button 49 is pressed, the outer lid 4 can be pushed further downward than when it is closed and locked. A movable gap is formed between the case 9 and the case 9. As a result, the outer lid 4 is pushed in the direction in which the outer lid 4 is further closed in accordance with the operation of pushing the locking release button 49 provided on the outer side of the outer lid 4 of the dust collecting chamber 3. That is, the repulsive force further increases. As a result, even if the biasing force of the spring 101 against the outer lid 4 in the closed state is set small, the biasing force in the direction to open the outer lid 4 can be increased when the locking release button 49 is pressed. It becomes possible, and the operation when opening the outer lid 4 becomes easy. In addition, this makes it possible to reduce the stress applied to the outer lid 4 or the main body case 1 when the outer lid 4 is closed.

  Furthermore, as shown in FIG. 9, it is preferable to provide the main body case 1 with a stopper 102 that limits the rotation of the arm 40 that supports the outer lid 4 to a certain width. As a result, the outer lid 4 that has been vigorously opened by the biasing force of the spring 101 is temporarily stopped by the stopper 102, so that safety can be ensured even if the outer lid 4 is suddenly opened. Since the outer lid 4 stopped by the stopper 102 has already been partially opened, it can be easily opened manually thereafter. In addition, as shown in FIG. 12, the engagement piece 47 of the outer lid 4 is arranged in a manner to come into contact with the engagement piece 97 of the dust collecting case 9 when the outer lid 4 is opened by a certain width. The rapid opening operation of the outer lid 4 can be temporarily stopped using the contact, or the speed of the opening operation can be reduced.

10 and 11 are a front view and a side view of the rotating handle 95 provided on the upper portion of the dust collecting case 9. Here, when the dust collecting case 9 is stored in the dust collecting chamber 3, the turning direction of the turning handle 95 is set to the same direction as the turning direction of the outer lid 4, and the rotation center shaft 106 of the turning handle 95 is rotated. A spring 107 is provided as a repulsive force generator that acts on the rotation handle 95 to urge the rotation handle 95 to always stand.
According to this configuration, the rotation handle 95 comes into contact with the inner surface of the outer lid 4 and urges the outer lid 4 to open in accordance with the movement of the rotation handle 95 of the dust collecting case 9 to the upright state. Bring auxiliary power. Therefore, with this configuration, the urging force provided on the rotation center shaft 100 of the outer lid 4 can be set small, and the stress applied to the outer lid 4 or the main body case 1 can be reduced.
The rotation handle 95 is preferably in contact with the outer cover 4 for as long as possible from the closed state of the outer lid 4 to the rotation handle 95 being almost upright. In addition, it is preferable to integrally provide a handle rib 60 and the like with which the tip end portion 95a abuts when the rotating handle 95 is raised.
Moreover, it is preferable that the contact part 95a with the inner surface of the outer cover 4 of the rotation handle 95 is a smooth curved surface as shown in FIG.
