Description

Detailed Description of the Invention (Technical Field) The present invention relates to a vacuum cleaner in which a dust collection bag is stored in a bag storage section of a vacuum cleaner body, and the dust collection bag collects and accumulates dust in a suction air flow. In particular, it relates to a mechanism for preventing forgetting to insert a dust collection bag.

(Prior art) Generally, this type of vacuum cleaner has a structure in which a dust collection bag is stored in a bag storage part and the opening of the bag storage part is closed with a lid. Since the structure is such that it can be closed even when a dust bag is not present, it is not possible to check the presence or absence of a dust bag from the outside, and there is a risk of driving with the dust bag forgotten. In this case, air containing dust passes through the inside of the electric blower and is discharged from the exhaust port, and the dust not only scatters indoors and is unsanitary, but also adheres to the windings of the motor of the electric blower, reducing its lifespan. , Misuse may lead to various drawbacks.

(Purpose) The present invention has been made in view of the above points, and has a structure in which the top cover cannot be closed when there is no dust collection bag in the bag storage section of the vacuum cleaner body, and the presence or absence of the dust collection bag is determined based on the state of the top lid. It is designed to be easily recognized and to prevent misuse as in the past.

(Example) Examples of the present invention shown in the drawings will be described in detail below.

In the figure, a vacuum cleaner body 1 has an outer shell made up of an upper body case 2 and a lower body case 3, and has a flexible wheel 4 and a running wheel 5 at the bottom, a handle 6 at the front end, and an exhaust lower at the rear end. An electric blower 8, a cord reel 9, etc. are arranged inside the rear part. Further, the vacuum cleaner body 1 has a bag storage section 10 with an upper opening at the front part, and the rear side of the bag storage section 10 (this is the opening on the suction side of the electric blower 8), and a ventilation frame 11 is disposed in the opening. The suction pipe 12 has one end as a suction port I3 and the other end as a vent 14, and the vacuum cleaner body 1
A suction port 13 is opened outward and a ventilation port 14 is opened in the front end of the bag storage section 10.

The dust collection bag 15 is stored in and out of the bag storage section 10 through its top opening, and as shown in FIG. It is composed of a cover plate 18 which is pivoted to be openable and closable at 16. The lid plate 18 has an elastic locking piece I9 formed on its upper edge, and is held in the closed position by engaging this locking piece 19 with a protrusion on the mouth frame 16 side, and by releasing the engagement. Open. The lid plate 18 has an opening 20 in the center, and a gasket 2I is installed in the opening 2o. Therefore, dust collection bag 1 having such a configuration
Reference numeral 5 indicates that the mouth portion 20 is locked and held by a bag locking means in a state where it is aligned with the vent hole 4, and the space between the mouth portion 20 and the vent hole 14 is kept airtight by a gasket 21.

The bag locking means includes a protrusion 22 integrally provided on the bottom wall of the bag storage section 10, a protrusion 23 integrally provided on the upper part of the front wall of the bag storage section 1o, and a top surface of the lid plate 18. The dust collection bag 15 consists of a protrusion 23 and a locking part 24 that engages and disengages. First, the lower part of the mouth frame 16 is engaged with the front side of the protrusion 22, and in this state, the dust collection bag 15 is closed to the locking part 2.
4 to the protrusion 23, the opening 2o becomes the ventilation hole 1.
4 and is locked and held in this state.

The upper lid 25 opens and closes the upper opening of the bag storage section 1o.
The rear edge side is pivoted to the cleaner body 1, and the front edge is equipped with a clamp device 26. This clamping device 26 consists of an engaging body 27 that can freely come out and retract, a spring 28 that always moves the engaging body 27 in the outward direction, and a clamp heir 29 that moves the engaging body 27 backward in the step direction against the spring 28. The tip of the engaging body 27 is inserted into and engaged with the retaining hole 30 of the cleaner body 1 to lock the upper lid 25 in the closed position. The upper lid 25 airtightly closes the upper opening of the bag storage section 10 with a gasket 31.

The mechanism for preventing forgetting to insert the dust collection bag 15 is assembled around a collar 32 that is integrally molded with the main body upper case 2 at one side of the upper opening of the bag storage section 10. This forget-to-insert prevention mechanism includes a support plate 33 attached to the lower surface of the collar 32 with screws at an appropriate interval of 1♦14, and a rod-shaped opening/closing actuator 34 inserted into the support plate 33 and the collar 32 so as to be vertically movable. A splinter 35 that always urges the actuating body 34 upward, and a through hole 37 that is disposed on the lower surface of the support plate 33 so as to be slidable in the front and rear direction and into which the lower end of the opening/closing actuating body 34 can be inserted. It is composed of a plate-shaped regulating body 36 having a hole therein, and a spring 38 that constantly urges the regulating body 36 rearward to position the through hole 37 at a position offset from the lower end of the opening/closing actuating body 34. At the front end of the dust collection bag 15, for example, the mouth frame 16
A hook-shaped piece 39 that engages with the hook portion 36a is formed at a proper position. In addition, 40 in the figure indicates a protrusion that is provided protrudingly on the lower surface of the upper lid 25 and comes into contact with the upper end of the opening/closing actuator 34.

(Operation of the embodiment) In the above configuration, when the dust collection bag I5 is to be stored in the bag storage section 10, the lower part of the mouth frame 16 is engaged with the front side of the protruding piece 22, as shown by the solid line in FIG. At the same time, the hook-shaped piece 39 is hooked on the hook portion 36a of the regulating body 36, and then the mouth frame 16 is pulled up from the solid line position to the two-dot chain line position. Then, along with this movement, the regulating body 36 is slid forward against the spring 38, and the through hole 37 comes to oppose the lower end of the opening/closing actuating body 34, so that the downward movement of the opening/closing actuating body 34, that is, the upper lid 25 The state allows movement to the closed position. Therefore, the dust collection bag 15 is attached to the protrusion 2.
In addition to the engagement between the part 3 and the locking part 24, the part 20 is locked and held in a state aligned with the vent hole 14 by the action of the protruding piece 22'.

Therefore, in such a state, the shift in the movement of the top cover 25 in the closing direction is due to the opening/closing ratio.Since the moving body 34 moves in the direction ① without being blocked by the regulating body 36, the top cover 25 can move to the closing position, and the moving body 34 can move to the closing position. It will be locked by a clamping device 26 (as shown in the third figure).

With the above, the waiting stage is completed, and in this state, the electric blower 8
The i16 is equipped with a floor suction port, an extension pipe, and a dust suction hose (
The dust-laden air sucked in through the air filter (not shown) enters the dust bag 15 from the suction pipe 12, where the dust is collected and removed, and then passed through the electric blower 8 and discharged from the exhaust air 7. As a result, cleaning work will be carried out.

Now, if you have forgotten to put in the dust bag 15, the regulator body 36
is in a position where the through hole 37 is shifted from the lower end of the opening/closing actuator 34 to prevent the opening/closing actuator 34 from cutting downward, and therefore the upper cover 25 cannot be moved to the closed position and is in the state shown in the fourth figure. By looking at the condition of the top cover 25, the user can easily recognize and recognize if he or she has forgotten to insert the dust collection bag 15.
Misuse can be avoided. Furthermore, even if the dust collection bag 15 is stored in the bag storage section 10, if a predetermined state is reached (the state in which the vent 14 and the opening 20 match), the top cover 25 will not be closed as described above. This can prevent misuse.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications in the bag locking means, the structure of the dust collection bag, etc., without departing from the gist of the invention. .

(Effects) According to the configuration of the present invention as described above, since the top lid cannot be closed if there is no dust collection bag in the bag storage section, the presence or absence of the dust collection bag can be easily recognized from the state of the top lid, and it is possible to Misuse can be prevented.
