Description

  The present invention relates to a vacuum cleaner, and more particularly to an automatic setting of a dust collection paper pack and a bypass air passage.

  In recent years, when a paper pack, which is a dust collection bag, is set in the dust collection chamber of the vacuum cleaner body, a mount support plate having a mount guide rail on both sides for guiding insertion of the mount (frame) of the paper pack is provided. It tends to improve insertability by providing. When a paper pack is set in the dust collection chamber of the main body, it is known that the paper pack is fixed at a normal position by raising the paper pack by hand and setting it on a paper pack fixing part. (For example, refer to Patent Document 1).

JP 2007-97632 A (pages 7 to 8, FIGS. 7 and 10)

However, in the conventional vacuum cleaner described in Patent Document 1, when the paper pack is set in the dust collection chamber of the main body of the vacuum cleaner, the paper pack is first inserted, and then the hook portion of the paper pack fixing part After that, it is necessary to perform a three-step operation such as closing the lid after confirming that the paper pack is fixed to the paper pack fixing part, and the work is complicated. Further, when the mount of the paper pack is accommodated in the dust collection chamber, this accommodation operation is very complicated for a person with bad eyes or a handicapped person.
In addition, when the dust bag of the paper pack is filled with dust, the dust bag expands and adheres to the back surface of the lid, so there is a problem that the suction path cannot be secured and the suction performance is significantly reduced. .

The present invention has been made to solve such problems, and a first object is to maintain the suction performance even when the dust bag of the paper pack is filled with dust. It is to provide a possible vacuum cleaner.
A second object is to provide a vacuum cleaner capable of automatically setting a paper pack in the main body dust collection chamber in conjunction with the closing operation of the lid of the main body of the vacuum cleaner.

A vacuum cleaner according to the present invention includes a dust collection chamber that houses a paper pack made of a dust collection bag and a mount, and a lid that covers an upper opening of the dust collection chamber so as to be openable and closable. A case having a pair of side walls erected almost vertically from both sides of the bottom is provided on the back surface, and is disposed in the dust collecting chamber, and the mount of the paper pack is inserted from above to below so that at least both sides of the mount are The paper pack insertion guide to be supported and the lower case that houses the dust collection chamber are the parts where the lower end of the mount inserted into the paper pack insertion guide reaches and stops. Inserting a paper pack with a recess, a seal packing provided at the hose connection port on the front wall of the dust collection chamber, and a paper pack fixing part that holds the mount in a position where the mount is pressed against the seal packing The guide has almost lead at the front end The rear end is a horizontal plate that connects two plate-like side portions that gradually increase as the distance between the rear end and the front end increases upward from the lower portion, and the front ends of the both side portions. And a guide rail extending substantially vertically from the rear end of each side surface so as to face the horizontal portion, and the paper pack fixing component is rotatably provided on the horizontal portion of the paper pack insertion guide. And a rear end portion having an outwardly convex curved surface, a claw portion provided in front of the rear end portion, and a top end portion of a mount of the paper pack provided in front of the claw portion. It is equipped with a mount holding recess to hold the paper pack, and the front end of the side wall of the case has a wide slope as it goes upward, and it is inserted into the guide rail of the paper pack insertion guide as the lid closes. By pushing the mounted board forward, it turns forward with the turning recess as a turning fulcrum. The mount is brought into contact with the rear end of the paper pack fixing part by the forward rotation due to the inclination of the front end, and then the nail is pushed up along the curved surface of the rear end and further pressed against the seal packing. In the position where it goes over the claw part, it fits into the concave part for holding the mount, and the paper pack fixing part is configured so that the rear end part hangs down by its own weight or inferior force, and the rib provided on the back of the lid And a protrusion provided on the paper pack fixing component, and the protrusion prevents the lid from closing by contacting the rib when the mount is not inserted into the guide rail .

  According to the present invention, because the case has a high resistance, the dust bag of the paper pack swollen due to dust full is prohibited from approaching the lid from the bottom of the case. Can be prevented. Further, since the surface of the case is flat and smooth, there is no problem that the dust bag is broken even if the dust bag of the paper pack is pressed with a considerably high pressure. In addition, since there is no protrusion on the back of the main body, even if you want to decorate the design surface of the lid of the main body, the receiving part of the receiving jig does not become uneven, the degree of freedom of decoration is high, and mass production Yield is also very good.

FIG. 2A is a perspective view showing a state immediately after the paper pack 6 is mounted, and only the mount is visible. FIG. 2B is a front view, and FIG. 2C is a side view.

FIG. 3 is a schematic exploded perspective view showing the configuration of the vacuum cleaner body 5 of the vacuum cleaner according to the present invention, and FIG. 4 is a detailed exploded perspective view of the vacuum cleaner body 5 of the vacuum cleaner according to the present invention. FIG.
Next, the structure of the electric vacuum cleaner main body 5 is demonstrated using FIGS.
As shown in FIGS. 2 to 4, the vacuum cleaner body 5 of the electric vacuum cleaner 100 is attached to the lid 51, the upper case 52, the lower case 53, and the lower case 53, and the vacuum cleaner body 5 is held by hand. A handle 54 for enabling carrying, a front wheel 55 attached to the lower case 53, and two rear wheels 56 having a diameter larger than that of the front wheel and supporting the lower case 53 so as to be rotatable. I have.

Next, the internal configuration of the lower case 53 will be described.
In FIG. 3, the left side is referred to as front and the right side is referred to as rear. A dust collection chamber 531 is provided in front of the lower case 53, and a suction power unit 532 is provided in the rear. Further, a separator 533 is provided between the dust collection chamber 531 and the suction power unit 532, and a filter for capturing fine dust such as a HEPA filter is installed here. In addition, a hose connection port, which is an opening connected to the hose 4, is formed in front of the lower case 53 so as to communicate with the dust collecting chamber 531. This hose connection port is a seal packing made of an elastic member such as rubber. 534 is covered.
The suction power unit 532 is composed of, for example, a motor, and sucks outside air containing dust from the suction tool 1 into the dust collection bag provided in the dust collection chamber 531 through the flow path by energizing the motor. . In addition, the cleaner body 5 is provided with a control board 535, a display unit, a cord reel unit 536, an exhaust port, and the like.

  The dust-containing air flowing from the outside of the cleaner body 5 passes through the paper pack 6 through the hose connection port, and is filtered by the paper pack 6. The filtered air is a HEPA filter provided in the separator 533. The filter unit, the suction power unit 532, and the exhaust port (not shown) are sequentially discharged to the outside of the cleaner body 5.

Next, the internal configuration of the dust collection chamber 531 will be described. FIG. 5 is a side sectional view showing the configuration of the main body 5 of the electric vacuum cleaner according to the present invention, and shows a state immediately after the paper pack 6 is inserted into the paper pack insertion guide 82. FIG. 5A is a side sectional view showing the entire configuration of the vacuum cleaner main body 5 of the vacuum cleaner, and FIG. 5B is an enlarged view of a main part indicated by a circle in FIG. 5A. FIG. FIG. 6 is a side sectional view showing the configuration of the vacuum cleaner main body 5 of the vacuum cleaner according to the present invention, and shows a state where the paper pack 6 is mounted on the paper pack fixing part 81 at the same time. FIG. 6A is a side sectional view showing the entire configuration of the vacuum cleaner main body 5 of the vacuum cleaner, and FIG. 6B is an enlarged view of a main part indicated by a circle in FIG. 6A. FIG.
As shown in FIG. 5A, a paper pack fixing part 81 and a paper pack insertion guide 82 (corresponding to the above-mentioned mount support plate) are provided inside the dust collection chamber 531.
The paper pack fixing component 81 is for fixing the paper pack 6 at a predetermined position, which will be described later. As shown in FIG. 5B, the paper pack fixing component 81 is rotated around the lower end of the center and the upper end of the horizontal portion 822 of the paper pack insertion guide 82. A moving shaft 811 is provided and supported by the rotating shaft 811 so as to be rotatable in the vertical direction. The lower end of the rear end portion 812 is formed by a substantially arcuate curved surface having a cross-sectional shape protruding outward. Further, a claw portion 813 is formed at the lower end of the rear end portion 812, and a concave portion 814 that fits with the upper end portion of the mount 61 of the paper pack 6 is formed between the claw portion 813 and the rotation shaft 811. ing.

When the paper pack 6 is not mounted, the paper pack fixing component 81 is rotated slightly downward and hangs downward as shown in FIG. 5B. It is configured. In order to realize this, the center of gravity of the paper pack fixing part 81 may be configured to be behind the rotation shaft 811, or a spring that applies a biasing force to the rear may be used.
In this state, the protrusion 815 provided on the paper pack fixing component 81 is positioned so as to be the highest. Even if the user attempts to close the lid 51, the rib 511 provided on the lid 51 and the protrusion 815 of the paper pack fixing part 81 come into contact with each other before the lid 51 is completely closed, so the lid 51 is not completely closed. . Thereby, the user can recognize that the paper pack 6 is not attached to the paper pack fixing component 81 by examining the reason why the lid does not close. That is, the protruding portion 815 of the paper pack fixing component 81 and the rib 511 of the lid 51 are means for detecting whether the paper pack is not attached.
The rib recess 83 provided in the bottom of the lower case 53 is a place where the lower end of the mount 61 finally reaches and stops when the paper pack 6 is inserted along the paper pack insertion guide 82. The upper portion of the mount 61 can be manually rotated in the front-rear direction using the rib recess 83 as a rotation fulcrum.

  FIG. 7 is a diagram showing the configuration of the paper pack insertion guide of FIG. 5, and shows the procedure for setting the paper pack 6 at the same time. As shown in FIG. 7, the paper pack insertion guide 82 has two trapezoidal side surfaces with a front end standing substantially vertically and a slope that gradually decreases in width as the rear end advances downward from the top. 821, a beam-like horizontal portion 822 that connects the front ends of both side surface portions 821 and 821, and a guide rail that extends substantially vertically from the rear end of each side surface portion 821 and 821 to face the horizontal portion 822. 823, 823. The cross-sectional shape of the paper pack insertion guide 82 cut along a horizontal plane is substantially C-shaped.

Next, the procedure for setting the paper pack 6 will be described with reference to FIGS.
When the paper pack 6 is set in the dust collecting chamber 531 in a state where the paper pack 6 is not attached, first, the paper pack 6 is loaded from above the paper pack insertion guide 82 as shown in FIG. Insert it toward the pack insertion guide 82. In this case, since the width of the upper side surface portion 821 of the paper pack insertion guide 82 is the largest, the opening area of the insertion opening is large and the insertion is easy. Further, when the mount 61 is inserted, if both sides of the lower end of the mount 61 and the lower surface of the mount 61 are placed on the guide rails 823 at both ends and are slid downward along the guide rails 823, the insertion becomes smooth. .
Although only the mount 61 is shown in FIG. 7, the paper pack 6 in which the mount 61 and the dust bag 62 are integrated is actually inserted. If the dust collection bag 62 is also illustrated together, it will be difficult to explain, so only the mount 61 is shown for convenience.
By inserting both ends of the mount 61 of the paper pack 6 along the guide rails 823 in this way, the lower end of the mount 61 moves forward as the downward insertion proceeds. Therefore, as the insertion of the mount 61 proceeds, the center of gravity of the mount 61 gradually moves to the guide rail 823 side, so that the mount 61 falls down to the guide rail 823 side. Unless the upper portion of the mount is intentionally brought to the forefront portion in the paper pack insertion guide 82, the mount 61 can be finally inserted in a state of being placed on the guide rail 823.
For this reason, even if the mount 61 is inserted into the paper pack insertion guide 82 with the upper end portion of the mount 61 inclined slightly forward than the lower end portion, the insertion tilt angle of the mount can be inserted without any trouble by the above-described tilting mechanism. The degree of freedom increases, and the insertion operation is easy.

Here, it is important that, unlike the conventional example, no spring is used. Not only is the paper pack easy to insert without using a spring, but the spring is not used, so the weight of the cleaner body 5 is reduced accordingly. Further, there is an advantage that the dust collection capacity of the spring integral volume paper pack is larger than the conventional one.
Next, when the lower end of the mount 61 passes through the lower end of the guide rail 823 and comes into contact with the rib recess 83 of the rib provided at the bottom of the lower case 53, the movement of the mount 61 stops there, and the insertion of the mount 61 is stopped. Complete. The state at this time is shown in FIGS. 5A, 5B and 7B.

Next, the upper part of the mount 61 is manually pushed forward. As a result, the paper pack 6 rotates forward with the rib recess 83 where the lower end of the mount 61 is positioned as a fulcrum, and the upper end of the mount 61 contacts the rear end 812 of the paper pack fixing component 81. Further, when the upper portion of the mount 61 is manually pushed forward, the rear end portion 812 is configured by a substantially arcuate curved surface having a cross-sectional shape protruding outward, so that the rear end portion 812 of the paper pack fixing component 81 is The upper end is lifted upward about the rotation shaft 811. Then, when the pushing further proceeds and the claw portion 813 of the paper pack fixing component 81 is placed over the upper end portion of the mount 61, the upper end portion of the mount 61 is fitted into the recess 814 of the paper pack fixing component 81. Fixed and the set is complete. At this time, the paper pack fixing part 81 holds the upper portion of the mount 61 in a state where the mount 61 is pressed against the seal packing 534 shown in FIGS. 4 and 6A, and the hole 61H of the mount 61 shown in FIG. The mouth 534H is positioned so as to coincide. The state at this time is shown in FIGS. 6A, 6B and 7C.
As a result, the hole 61H of the mount 61 and the hose connection port 534H communicate with each other in a close contact state, so that all dust sucked from the hose connection port 534H is sucked into the dust bag 62 and does not leak to the rest.
In the above example, the shape of the side surface portion 821 is substantially trapezoidal, but it is not necessary to be limited to this. For example, a downwardly convex C-shaped curve (a curve drawn by a so-called slide) may be used.

Next, means for securing the paper pack automatic setting and the bypass air passage will be described.
FIG. 8 is a configuration diagram of a case 514 (means for securing a paper pack automatic setting and a bypass air passage) showing the first embodiment of the electric vacuum cleaner according to the present invention. FIG. 8A is a diagram showing the arrangement position of the case 514 provided on the lid 51 of the electric vacuum cleaner main body 5, and FIG. 8B is a front sectional view of the electric vacuum cleaner main body 5. In the figure, the same reference numerals as those in FIG. 5 denote the same or corresponding parts. In FIG. 8, the case 514 includes a bottom portion 5141 and a pair of side walls 5142 and 5142 erected almost vertically from both sides of the bottom portion 5141, and the side walls 5142 extend further forward than the bottom portion 5141. The portion in front of the bottom portion 5141 is also extended below the bottom portion 5141. In addition, the front end of the side wall 5142 of the case 514 has an inclination 5143 that becomes wider as it goes upward, and the portion in front of the bottom 5141 of the side wall 5142 has a U-shape or V-shape as a whole. A drawing surface is formed. The case 514 configured as described above is provided on the back surface of the lid 51, and the direction of the side wall 5142 is substantially parallel to the longitudinal direction of the lid 51. The slope 5143 at the tip of the side wall 5142 constitutes a paper pack automatic setting means.
The front end and the rear end of the case 514 are open.

9 is an explanatory view showing automatic setting (automatic mounting) of a paper pack in the configuration of FIG. 8, and FIG. 9 (a) is a side sectional view of the main body of the electric vacuum cleaner before the lid 51 is closed. (B) is a sectional side view of the main body of the electric vacuum cleaner after the lid 51 is closed. In the figure, the same reference numerals as those in FIGS. 5 and 8 denote the same or corresponding parts.
Next, automatic paper pack setting will be described with reference to FIG.
The user manually inserts the mount 61 of the paper pack 6 into the guide rail 823 of the paper pack insertion guide 82, the lower end of the mount 61 reaches the rib recess 83 and stops, and the insertion into the guide rail 823 is completed. After confirming the above, the lid 51 is manually closed. When the lid 51 is manually closed, as the lid 51 descends to the closed position, the inclined front end 5143 of the side wall 5142 of the case 514 provided on the back surface of the lid 51 is guided by the guide rail 823 as shown in FIG. It abuts on the upper part of the mount 61 inserted into the cardboard and pushes the mount 61 forward. As a result, the mount 61 rotates forward with the rib recess 83 as a rotation fulcrum, and the rib 511 provided on the back surface of the lid 51 shown in FIG. 5B is formed on the protrusion 815 of the paper pack fixing part 81. Before the contact, after contacting the rear end portion of the paper pack fixing component 81, the claw portion 813 is pushed up along the curved surface of the rear end portion and further pressed against the seal packing 534. And is fitted into the recess 814. Thus, the automatic setting of the paper pack 6 is completed.

  As described above, by using the paper pack automatic setting (automatic mounting) means, the user can mount the paper pack 6 on the guide rail 823 of the paper pack insertion guide 82 when mounting the paper pack 6 in the dust collecting chamber 531. Simply insert and close the lid 51. That is, since the trouble of manually pressing the mount 61 and mounting it on the paper pack fixing part 81 can be saved, the operation load on the user is greatly reduced.

FIG. 10 is an explanatory diagram showing the configuration of the bypass air passage in the first embodiment of the electric vacuum cleaner according to the present invention. FIG. 10A is a view showing the air flow before the dust bag 62 of the paper pack 6 is full, and FIG. 10B is a diagram where the dust bag 62 of the paper pack 6 is filled with dust. It is a figure which shows the flow of the air of the state which became.
When the vacuum cleaner is operated until the inside of the dust bag of the paper pack is full, the dust bag is swelled by the suction force of the suction power unit 532 as shown in FIG. Air passes through the suction tool 1, the suction pipe 2, the connection pipe 3 and the hose 4 of FIG. 1, and the dust collection bag of the paper pack 6 through the hose connection port with the seal packing 534 and the hole of the paper pack mount 61. 62 flows in. The air flow in which the dust is captured by the dust bag 62 is divided into a main flow and a bypass flow. After the fine dust is removed by passing through the rear filter, the main flow of the air is separated into the separator 533 and the suction power unit 532. It passes through the (motor) and is discharged to the outside through the exhaust port.
On the other hand, the bypass flow flows from the upper part of the dust bag 62 into the case 514 through the opening at the front end of the case 514, passes through the separator 533 and the suction power unit 532 from the opening at the rear end of the case 514, and is exhausted (see FIG. (Not shown) is discharged to the outside.

When the operation of the vacuum cleaner 100 is continued in a state where the dust collection bag 62 of the paper pack 6 is filled with dust, the dust is accumulated and compressed sequentially from the downstream side of the main air path of the dust collection bag 62. go. Then, dust accumulates from the side facing the mount 61 in the dust collection bag 62 (the right side of the dust collection bag 62 in FIG. 10A), and further accumulates in the lower part of the dust collection chamber 531 due to gravity.
If the bypass path is not secured, the dust bag 62 will eventually fill up with dust, filling the downstream side of the dust collection chamber 531 (the right side in the dust collection chamber 531 in FIG. 10A) and the bottom, It reaches the upper part (lid 51) of the dust collection chamber 531 and comes into close contact with the lid 51. In this case, the main flow path is clogged and the air path is gradually narrowed, so that the pressure loss is increased and the suction performance is drastically decreased. Despite the fact that the front part of the dust bag 62 still has the capacity to store dust, it eventually becomes almost unflowable and cannot be sucked, and although it consumes a lot of power, it cannot be sucked. Occur. In addition, since air for cooling the motor cannot be secured, if the operation is continued for a long time, the heat generated by the motor accumulates, which may cause the motor to burn out.

  Therefore, the above-described problem can be solved by configuring the bypass air passage with the opening formed at the rear end of the case 514, the opening at the rear end, and the hollow portion of the case 514 and the pipe 51. When the dust collection bag 62 becomes full, the dust collection bag 62 eventually fills the downstream side of the mainstream in the dust collection chamber 531 (the right side of the dust collection chamber in FIG. 10A) and the bottom, and the upper part of the dust collection chamber 531. Although it tries to reach (the lid 51), the case 51 cannot fill up the lid 51. At this time, since the main air flow path of the air is blocked, the air flow path flows through the bypass air path as shown in FIG. 9B. That is, the dust bag 62 enters the upstream (left side in FIG. 9) that is not yet clogged and has a storage capacity, and then rises upward from the dust bag 62 to exit the dust bag 62, and the case 514 It flows into the opening at the front end, passes through the inside of the case 514, exits from the opening at the rear end of the case 514, descends, passes through the separator 533 and the suction power unit 532, and exits from the exhaust port (not shown). Discharged.

  Since the dust collection bag is filled with dust in this way, a bypass air passage can be ensured even if the main air passage is blocked, so that the suction performance of the vacuum cleaner can be maintained. In addition, since air for cooling the motor, which is the suction power unit, can be secured, the motor does not burn. Further, as shown in FIG. 14, even if a plurality of wall surfaces are arranged in parallel on the back surface of the lid 51, the bypass flow path can be secured by preventing adhesion to the lid of the dust bag that is filled with dust and inflated, In this case, the dust collection bag 62 is easily damaged when the dust collection bag 62 pushes the rib. On the other hand, since the surface of the bottom portion 5141 of the case 514 in FIG. 8 is flat, there is no problem that the dust bag is broken even if the dust bag of the paper pack is pressed with a considerably high pressure.

  FIG. 11 is a view showing another example of the lid case of the electric vacuum cleaner according to the present invention. In the figure, the same reference numerals as those in FIG. 8 denote the same or corresponding parts. The case 514A includes a bottom portion 5141A configured with a smooth uneven surface having a corrugated cross-sectional shape, and is different from the case of FIG. As shown in FIG. 14, even if a plurality of wall surfaces (projected surfaces) having no bottom are arranged in parallel on the back surface of the lid 51, the dust collection bag 62 that is filled with dust and inflated is prevented from sticking to the lid 51. Although the bypass air passage can be secured, in this case, the dust collection bag 62 is easily damaged when the dust collection bag 62 pushes the wall surface. In contrast, since the surface of the bottom portion 5141A of the case 514A in FIG. 11 is a smooth curved surface, there is no problem that the dust bag 62 is damaged. Further, since the bottom portion 5141A is formed of an uneven surface, the strength is higher than that of the bottom portion 5141 in FIG. In addition, since the case 514A is a separate part from the lid 51 and there is no protrusion on the back surface of the lid 51, even if it is desired to decorate the design surface of the lid 51, the receiving portion of the receiving jig may be uneven. There is also a high degree of freedom for decoration, and the yield of mass production is also very good.

Moreover, FIG. 12 is a figure which shows another example of the case of the lid | cover of the vacuum cleaner which concerns on this invention. In the figure, the same reference numerals as those in FIG. 8 denote the same or corresponding parts. The case 514B includes a bottom portion 5141B formed of a smooth uneven surface having a corrugated cross-sectional shape similar to that of the case 514A, but is different from the case of FIG.
Moreover, the point to which the design of the lid 51 is applied is different from that in FIG. 8 in that it is a separate part for decoration.
As described above, since the surface of the bottom portion 5141B of the case 514B is a smooth curved surface, the dust bag 62 is hardly damaged.
