Description

  The present invention relates to a vacuum cleaner, and more particularly to an improvement in a structure for holding a mount of a dust collection paper pack.

  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. Also, a separate spring is fixed to the bottom of the lower case of the vacuum cleaner, and the upper part of the backing plate is pivoted back to a predetermined angle with the lower end of this backing plate as a fulcrum by the biasing force of this spring. In addition, there is known a vacuum cleaner in which the holding force of the mount and the fixing force of the mount support plate are strengthened by the biasing force of the spring. In such a vacuum cleaner, after the mount is inserted along the mount guide rail of the mount support plate by manual operation, the mount is manually rotated to a predetermined position forward against the biasing force of the spring. The set is completed by fixing the mount with a paper pack fixing component (see, for example, Patent Document 1).

Japanese Patent No. 3144421

However, the conventional vacuum cleaner described in Patent Document 1 has a problem in that the weight of the vacuum cleaner increases correspondingly because a separate spring is provided. Further, since the paper pack cannot be enlarged by the area occupied by the spring, there is a problem that the dust collection capacity is reduced accordingly.
Moreover, in order to reduce the manufacturing cost of a vacuum cleaner, it is possible to use the same lower case and to share a cyclone type vacuum cleaner and a paper pack type vacuum cleaner. In this case, the cyclone unit, which is a cyclone type dust collector, is housed in the dust collection chamber instead of the paper pack, but the case of the cyclone unit must be made of a material having a relatively high hardness for handling. Because of the lack of flexibility, when a spring is provided, the size of the cyclone unit must be reduced by the area occupied by the spring, and the dust collection capacity is reduced accordingly.

  The present invention has been made to solve such problems, not only switching the dust collection type between the paper pack type and the cyclone type, but also increasing the degree of freedom of model development and inserting the paper pack. It aims at providing the vacuum cleaner which can improve the property.

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, a lid that covers the upper opening of the dust collection chamber so as to be openable and closable, and a paper pack disposed in the dust collection chamber. A paper pack insertion guide that is inserted from the top to the bottom and supports at least both sides of the mount, and a lower case that houses the dust collection chamber, and the lower end of the mount inserted in the paper pack insertion guide reaches and a first recess serving as the rotation fulcrum of and mount a part that stops, the seal packing provided on the hose connecting port of the front wall of the dust collecting chamber, the mount is rotating the first recess as a rotation fulcrum by an external force It is equipped with a paper pack fixing part that holds the upper part of the mount in a position that moves and is pressed against the seal packing by an external force.The paper pack insertion guide has a front end standing almost vertically and a rear end, The distance between this rear end and the front end is lower Two plate-shaped side surfaces that gradually increase as they move upward, a horizontal part that connects the front ends of both side parts, and a substantially vertical extension from the rear end of each side part to face the horizontal part The paper pack fixing part is rotatably supported by the paper pack insertion guide, and is provided with a rib provided at the bottom of the dust collection chamber, and a cyclone type that can be stored in the dust collection chamber. The paper pack insertion guide has a second recess that is detachably fitted to the rib, and a cyclone type dust collection unit is housed in the dust collection chamber instead of the paper pack. In this case, a cyclone type dust collection unit is accommodated from the top to the bottom in the dust collection chamber after the paper pack insertion guide is removed from the rib and removed from the dust collection chamber .

  According to the present invention, the paper pack insertion guide has a plate-like shape in which the front end stands substantially vertically and the rear end gradually increases as the distance between the rear end and the front end progresses upward from the bottom. Since it is composed of two side parts, a beam-like horizontal part that connects the front ends of both side parts, and a guide rail that extends substantially vertically from the rear end of each side part, the insertion opening becomes wider The paper pack can be easily inserted. In addition, the paper pack fixing part holds the top of the mount in the position where the mount is pressed against the seal packing, so dust does not leak to other than the dust collection bag, and unlike the conventional case, no spring is used. The vacuum cleaner is lighter and the dust collection capacity of the paper pack is increased accordingly.

Thus, the vacuum cleaner main body of the vacuum cleaner according to the present invention has a structure that can be shared by both a paper pack type and a cyclone type, and is characterized by high versatility. Also, in the future, other types of paper packs and different types of cyclone units can share the lower case of this vacuum cleaner as long as they have the same shape and size as those used in the present invention. It is possible to increase the degree of freedom in proceeding with development.

FIG. 3 is a schematic exploded side 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. In FIG. 4, the case where the paper pack 6 is mounted is illustrated, but it goes without saying that the cyclone unit 7 may be mounted.
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 vacuum cleaner 100 is attached to the lid 51, the upper case 52, the lower case 53, and the lower case 53. 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 dust collecting chamber 531 can store the dust collecting paper pack 6 or the cyclone unit 7. 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 vacuum cleaner body 5 is provided with a control board 535, a display unit, a cord reel unit 536, an exhaust port, and the like.

  Dust-containing air that has flowed in from the outside of the vacuum cleaner body 5 passes through the paper pack 6 or the cyclone unit 7 through the hose connection port, and is filtered by the paper pack 6 or the cyclone unit 7. Is configured to be discharged out of the electric vacuum cleaner main body 5 through a filter unit such as a HEPA filter provided in the separator 533, a suction power unit 532, and an exhaust port (not shown) in this order.

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 lower case from which the suction power unit 532 of the paper pack type vacuum cleaner is removed, and FIGS. 5A to 5C show the procedure for mounting the paper pack. 5 (a) shows a state before the paper pack is inserted, FIG. 5 (b) shows a state immediately after the paper pack is inserted, and FIG. 5 (c) shows the paper pack 6 in the paper pack fixing part. 81 shows a state after mounting. 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. As shown in FIG. 6, a rotation shaft 811 is provided at the lower end of the central portion and the upper end portion of the horizontal portion 822 of the paper pack insertion guide 82. The lower end of the rear end portion 812 is formed of a substantially arc-shaped curved surface having a convex cross section outwardly with the rotating shaft 811 as a fulcrum. 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.

The paper pack fixing component 81 is configured such that when the paper pack 6 is not mounted, the rear end side of the paper pack fixing component 81 is rotated slightly downward and hangs downward. 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.
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. The rib recess 83 corresponds to the first recess of the present invention.

  FIG. 8 is a diagram showing a procedure for setting the paper pack 6 and shows a schematic configuration of the paper pack insertion guide 82 at the same time. As shown in FIG. 8, the front end of the paper pack insertion guide 82 stands substantially vertically, and the rear end gradually increases as the distance between the rear end and the front end advances from the lower part to the upper part. Two substantially trapezoidal side surfaces 821 having an inclination, a beam-shaped horizontal portion 822 connecting the front ends of both side surface portions 821 and 821, and the horizontal portion 822 from the rear ends of the side surfaces 821 and 821 are opposed to each other. Thus, the guide rails 823 and 823 are extended substantially vertically. The cross-sectional shape of the paper pack insertion guide 82 cut along a horizontal plane is substantially C-shaped.

Next, a 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 as shown in FIG. 5A, first, as shown in FIG. The paper is inserted from above the paper pack insertion guide 82 toward the paper 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. 8, 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 in the paper pack insertion guide 82, the mount 61 can be finally inserted in a state where it is 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.
In addition, as shown in FIG. 7, you may extend the outward inclined surface so that the distance between both side surface parts 821 and 821 may become large gradually toward the upper end of the side part 821 upwards. Thereby, since the area | region of the insertion port of the mount 61 is expanded, insertion of the mount 61 becomes still easier.

Here, it is important that, unlike the conventional example, no spring is used. The insertion of the paper pack 6 is easy without using a spring, and the weight of the electric vacuum cleaner main body 5 is reduced correspondingly because the spring is not used. Further, there is an advantage that the dust collection capacity of the spring occupying integral paper pack 6 becomes larger than that of 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. 5B and 8B.

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. When the push-in further proceeds and the claw portion 813 of the paper pack fixing component 81 gets 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. Is fixed and the set is completed. At this time, the paper pack fixing component 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 FIG. 4, so that the hole 61H of the mount 61 and the hose connection port 534H shown in FIG. Is positioned. The state at this time is shown in FIGS. 5C, 5B and 8C.
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, a procedure for setting the cyclone unit 7 will be described.
9 is a configuration diagram of the paper pack insertion guide 82, FIG. 9A is a perspective view of the paper pack insertion guide 82 before the paper pack insertion guide holding rib 825 is fitted, and FIG. 9B is a paper pack. 9 is a perspective view of the paper pack insertion guide 82 after the insertion guide holding rib 825 is fitted, and FIG. 9C is a front cross-sectional view of the state in which the paper pack insertion guide holding rib 825 is fitted.
9, the same reference numerals as those in FIG. 6 denote the same or corresponding parts. The recess 824 is formed inside the forefront portion of the side surface portion 821 of the paper pack insertion guide 82. Further, the lower end of the paper pack insertion guide holding rib 825 is provided at the bottom portion of the lower case 53, and includes a fitting portion 8252 between the protruding portion 8251 and the recessed portion 824. When the vacuum cleaner is used as a paper pack type, the paper pack insertion guide holding ribs 825 are manually fitted into the paper pack insertion guide holding ribs 825 from above the paper pack insertion guide holding ribs 825 so that the paper pack insertion guide holding ribs are fitted. The fitting portion 8252 of 825 fits into the recess 824 of the paper pack insertion guide 82, and the protrusion 8251 of the paper pack insertion guide holding rib 825 is positioned in close contact with the outer wall surface of the horizontal portion 822 of the paper pack insertion guide 82. . As a result, the paper pack insertion guide 82 is fixed to the lower case 53 via the paper pack insertion guide holding rib 825. In order to closely fit the paper pack insertion guide holding rib 825 and the concave portion 824, the position of the paper pack insertion guide holding rib 825 is arranged slightly outside the position of the concave portion 824, and the upper portion thereof is the position of the concave portion 824. It may be configured to be the same as or slightly inside. The recess 824 corresponds to the second recess of the present invention.

  This paper pack insertion guide holding rib 825 is a structure for allowing the lower case 53 to be used in common for both the paper pack type vacuum cleaner and the cyclone type vacuum cleaner, and is one of the features of the present invention. is there. That is, when switching from the paper pack type to the cyclone type, the cyclone unit 7 is inserted and used instead of the paper pack 6, but the paper pack insertion guide 82 that interferes and interferes when the cyclone unit is inserted is fixed to the paper pack. It can be pulled out from the paper pack insertion guide holding rib 825 together with the component 81. The cyclone unit 7 can be inserted by pulling out the paper pack insertion guide 82 together with the paper pack fixing component 81 from the paper pack insertion guide holding rib 825.

  FIG. 10 is an external view of the cyclone unit 7 used in the electric vacuum cleaner according to the present invention. FIG. 10A is a perspective view of the cyclone unit 7. FIG. 10B is a front view of the cyclone unit 7 as viewed from the direction of the arrow A in FIG. FIG. 10C is a right side view of the cyclone unit 7 as viewed from the direction of arrow B in FIG. FIG. 10D is a rear view of the cyclone unit 7 as viewed from the direction of arrow C in FIG. As shown in FIG. 10, the shape of the case of the cyclone unit 7 is a box shape that can be fitted in the dust collection chamber 531 with the maximum capacity, and is made of a material having a relatively high hardness. The cyclone unit 7 includes an opening 7H connected to the hose connection port 534H, a swirling chamber that communicates with the opening 7H, efficiently converts dust-containing air into a swirling flow, and captures coarse dust efficiently, The filter chamber further comprises a filter for filtering relatively clean air from which dust has been filtered.

FIG. 11 is a diagram showing a procedure for switching the vacuum cleaner according to the present invention from the paper pack type to the cyclone type. Next, an operation procedure for switching the vacuum cleaner from the paper pack type to the cyclone type will be described with reference to FIG. In FIG. 11, thick arrows indicate operation procedures.
When the vacuum cleaner is switched from the paper pack type to the cyclone type, first, as shown in FIG. 11A, the lid 51 is manually opened, and the paper pack insertion guide 82 is manually pulled upward. By this operation, the paper pack insertion guide holding rib 825 that has been fitted in the recess 824 of the paper pack insertion guide 82 is disengaged and removed from the dust collecting chamber 531. Further, as shown in FIG. 11B, the paper pack fixing component 81 fixed to a part of the paper pack insertion guide 82 is pulled out together with the paper pack insertion guide 82. As a result, since there is no obstacle in the insertion of the cyclone unit 7 from the dust collection chamber 531 to the dust collection chamber 531, the cyclone unit 7 can be accommodated in the dust collection chamber 531.
Next, as shown in FIG. 11 (c), the cyclone unit 7 is inserted into the dust collecting chamber 531 from above with the bottom thereof facing down with the lid open. Then, as shown in FIG. 11 (d), when the insertion of the cyclone unit 7 into the dust collection chamber 531 is completed, the lid 51 is closed.

With the above simple operation procedure, switching from the paper pack type to the cyclone type is completed.
In the above operation, unlike the prior art, no spring is used, so the weight is reduced accordingly. Further, the size of the occupying volume integral cyclone unit of the spring can be increased as compared with the conventional case, and consequently, the cyclone dust collecting capacity can be increased.
Further, the process of removing or attaching the engagement with the spring at the time of switching is unnecessary, and the manufacturing cost can be reduced.
Further, since there is no spring, it is not necessary to apply a force against the urging force of the spring rearward when the mount 61 is rotated forward.
The concave portion 824 is formed in the vicinity of the front end portion of the side surface portion 821 of the paper pack insertion guide 82, and this side surface portion 821 is provided in the vicinity of the side wall of the front corner in the dust collection chamber 531. Further, the paper pack insertion guide holding rib 825 is provided at a position where it can be fitted into the recess 824. Since the paper pack insertion guide holding ribs 825 are provided in the vicinity of the front corners in the dust collecting chamber 531, the paper pack 6 or the cyclone unit 7 and the paper pack are stored when the paper pack 6 or the cyclone unit 7 is stored. Interference with the insertion guide holding rib 825 can be avoided.
Further, since the paper pack fixing component 81 is rotatably supported by the paper pack insertion guide 82, the paper pack insertion guide 82 is removed from the dust collection chamber 531 by disengaging the paper pack insertion guide 82 from the paper pack insertion guide holding rib 825. Since the paper pack fixing part 81 can be pulled out when pulling out, the dust collection capacity of the cyclone unit 7 is further improved.

As described above, the insertion property of the paper pack 6 can be improved while increasing the degree of freedom of switching the dust collection type and future model development.
Further, there is no adverse effect when the paper pack 6 is inserted into the paper pack insertion guide holding rib 825.
Moreover, since the spring of another component can be reduced, weight reduction can be achieved.
Moreover, even if the lower case is shared, the cyclone type dust collection capacity does not decrease.

  The vacuum cleaner according to the present invention can be used not only in a paper pack type but also in a cyclone type, and can be widely used in the industrial field of vacuum cleaners.
