Description

Electric vacuum cleaner {VACUUM CLEANER}

The present invention relates to an improvement of an electric vacuum cleaner having a dust collecting container for collecting dust suctioned detachably in the vacuum cleaner body.

Background Art Conventionally, a dust collecting container of a vacuum cleaner, that is, a dust cup, is known to have an accommodating form attached to the cleaner body in an invisible state and an exposure form attached to the cleaner body in an exposed state. The storage type has the following advantages over the exposure type because the dust collecting container has a structure in which the dust collecting container is accommodated in the dust collecting container chamber installed in the cleaner body and sealed by a cover provided in the dust collecting container chamber.

That is, when the dust collecting container of this accommodation type is applied to an electric vacuum cleaner having a cyclone-type dust collecting structure, in particular, the wind blowing sound of the cyclone is soundproofed, in other words, the wind blowing sound is not emitted to the outside of the cleaner body, so the noise is minimized. Can be suppressed. In addition, since the dust collecting container is not visible from the outside, no special design is required for the appearance of the cleaner body, the appearance can be simplified, and the appearance is also excellent.

However, the dust collecting container is often taken out of the dust collecting container chamber to discard the stored dust or for cleaning, and if the dust collecting container is closed while the cover of the dust collecting container chamber is forgotten, the dust collecting container is closed. Since it is not possible to know whether it is stored in the vacuum cleaner main body from the outside of the vacuum cleaner main body, the dust suction switch was often put in without the dust collecting container being stored in the dust collecting container chamber. In this way, when the electric blower is operated without storing the dust collecting container in the vacuum cleaner body, the dust sucked from the suction port is sucked into the electric blower, and therefore, the dust must be removed in the electric blower. Therefore, there was a problem that the electric blower is broken. Even when the secondary filter is installed upstream of the electric blower for the protection of the electric blower, the secondary filter immediately clogs and the cooling air of the electric blower is insufficient, or the foreign matter sucked through the secondary filter causes the electric blower to break. There has been a problem that the electric blower is broken due to being sucked inside.

In addition, a conventional vacuum cleaner is disclosed in Japanese Patent Application Laid-Open No. 1-291821 to prevent the lid of the storage chamber for accommodating the carton from closing when the carton is not mounted separately from the dust container type as described above. An electric vacuum cleaner is disclosed in Japanese Patent No. 3297224, in which a cleaner main body cannot be set when a bag is not mounted. The vacuum cleaners described in these publications are not intended to be used in a state where the cartons or dust collecting bags are not installed, but the lid cannot be closed or the main body cannot be set in this state, so that the transportation of the vacuum cleaner body is inconvenient in the non-mounting. Equipped with.

The present invention has been made in view of the prior art as described above, and its object is to suck dust even if a dust suction switch is put in the vacuum cleaner having an accommodating type dust collecting container, forgetting to attach the dust collecting container to the cleaner body. It is to provide an electric cleaner that can be prevented.

Another object of the present invention is to provide an electric vacuum cleaner capable of carrying a vacuum cleaner body even when the dust collecting container is completely accommodated in the vacuum cleaner body and thus the dust collecting container is not accommodated in the vacuum cleaner body.

In order to achieve the above object, in one aspect of the present invention, the electric vacuum cleaner is detachable from the vacuum cleaner main body and the dust collecting container chamber in which a connection port is formed in communication with the suction port body and the dust collection container chamber communicating with the connection port is formed therein. And an electric blower having a suction port communicating with the dust collection container equipped with the suction port communicating with the connection port and collecting dust collected from the suction port, and a suction opening communicating with the dust collection container mounted in the dust collecting chamber chamber. When the electric blower is driven without being mounted in the container chamber, a structure for suppressing the suction of dust from the inlet port is provided.

In one embodiment, the structure for suppressing the suction of the dust from the suction port is composed of a mechanism for introducing outside air into the dust collecting container chamber when the electric blower is driven.

The mechanism for introducing outside air into the dust collection chamber has a hole for communicating with the dust collection chamber and the outside air, and is configured such that the hole and the suction opening of the electric blower do not communicate when the dust collection container is mounted in the dust collection chamber. When dust is not attached to the dust collecting container chamber, the dust collecting container chamber is led to the outside air through the above-mentioned hole by the driving of the electric blower, so that suction of the dust from the suction port body is suppressed.

Further, in another embodiment, the structure for suppressing the suction of the dust from the inlet port includes a dust container container and a hole in which the outside air communicates, and an opening / closing member provided to be openable and open in the hole, and the dust container is a dust container chamber. The opening and closing member closes the hole so that the dust collecting container chamber and the outside air do not communicate when it is installed at the inside, and when the dust collecting container is not mounted, the opening and closing member moves downward due to the negative pressure driven by the electric blower. This open and dust collecting container chamber is configured to suppress the suction of dust from the suction inlet through the atmosphere.

According to the present invention, even if the electric blower is driven without forgetting to attach the dust collecting container to the cleaner main body, it is possible to prevent dust from being sucked in from the suction port body. Further, for example, even if the dust collecting container is not inserted into the main body, the lid of the dust collecting container chamber can be closed, and therefore, the cleaner main body can be transported.

[action]

Next, operation | movement of the vacuum cleaner comprised as mentioned above is demonstrated.

First, as shown in FIG. 2, the dust collecting container 50 is attached to the dust collecting container chamber 21 of the cleaner main body 11, and the dust collecting hose 12 is attached to the vacuum cleaner main body 11 as shown in FIG. The inlet port 15 is connected to the connection port 10A at the same time through the extension tube 14 through the handle operation tube 13.

The electric blower 23 is driven by operating the operation part 13A switch 13a of the handle operation tube 13. Air is sucked in from the suction opening 24 of the electric blower 23 by the driving of the electric blower 23, and acts on the rear opening 51 of the dust collecting container 50 via the connection air path G. Through the pleated filter body P, the negative pressure chamber 57 of the dust collecting container 50 becomes negative pressure. At this time, the state of communication between the hole 41 and the suction opening 24 of the electric blower 23 is blocked by the dust collecting container 50. Therefore, since the negative pressure does not act on the hole 41, the button 42 does not move downward.

The negative pressure caused by the driving of the electric blower 23 separates the dust through the filter F2 of the dust collecting chamber 55, in the dust collecting chamber 55 or through the net filter F1 of the dust separating unit 60 (60). The negative pressure acts on the dust collecting hose 12, the extension pipe 14, and the suction inlet body 15 through the suction port 52 of the dust collecting container 50, and acts on the air passage 62 of the dust collecting container 50. Dust is attracted with the air.

This sucked dust and air are sucked into the inlet port 52 of the dust collecting container 50 through the extension pipe 14 and the dust collecting hose 12. The dust and air sucked into the suction port 52 are sucked into the air path 62 of the dust separation unit 60.

A part of the air sucked into the air passage 62 is sucked into the negative pressure chamber 57 of the dust collecting container 50 through the net filter F1 of the dust separation unit 60, and further, the rear opening ( The suction opening 24 of the electric blower 23 is sucked through the pleated filter body P and the connection air path G of 51.

On the other hand, since the dust sucked in the air passage 62 of the dust separation unit 60 has a mass (larger) than the air, the dust flows straight through the air passage 62 by the inertia, and thus guide wall portion 101 of the extruded plate 100. Is introduced into the dust collecting chamber (55). That is, air and dust are separated by the dust separating unit 60, and the separated dust is collected by the dust collecting chamber unit 55.

In addition, the air that has been straight through the air path 62 is guided to the guide wall 101 of the extruded plate 100 and introduced into the dust collecting chamber 55. The air introduced into the dust collecting chamber 55 is sucked into the negative pressure chamber 57 of the dust collecting container 50 through the filter F2 of the rear wall 55H of the dust collecting chamber 55 and the dust collecting container 50. The suction opening 24 of the electric blower 23 is further sucked through the pleated filter body P and the connection air path G of the rear opening 51 of the.

When the cleaning is finished, the drive of the electric blower 23 is stopped by operating the switch 13A of the operation unit 13A. Subsequently, when the button 42 of the cleaner main body 11 is pressed downward, the lever 85 is pushed down against the pressing force of the springs S1 and S1 as shown in FIGS. 20-22.

When the lever 85 is pushed downward, the extruder plate 100 is pushed downward by the interlocking mechanism 70.

When the extruded plate 100 is pushed down, the blade 107 of the extruded plate 100 slides into contact with the filter face F2a of the filter F2, and the dust adhered to the filter face F2a. Remove it. In addition, the dust stored in the dust collecting chamber part 55 is compressed by pushing down the extrusion plate 100. For this reason, a lot of dust can be stored in the dust collecting chamber part 55.

When the hand is released from the button 42, the lever 85 returns to its original position by the pressing force of the springs S1 and S1, and the extruder plate 100 or the button 42 interlocks with the lever 85. Return to the original position as shown in 5.

Next, the case where the dust stored in the dust collecting chamber part 55 is discarded is demonstrated.

First, the cover 40 of the cleaner main body 11 is opened, and the dust collection container 50 is taken out. Subsequently, when the operating part 91A shown in FIG. 6 is pressed, the bottom cover 59 is rotated and opened in the direction of the arrow P1 about the axis J1 by the opening / closing mechanism 90.

Subsequently, when the lever 85 is gripped together with the grip part 54, as shown in FIG. 23, the lever 85 is pushed down toward the grip part 54, thereby pushing down the lever 85. As shown in FIG. 10, the extrusion plate 100 is pushed down to a position sufficient for discharging dust by the interlock mechanism 70. Thereby, since the dust in the dust collecting chamber part 55 is extruded downward from the bottom opening of the dust collecting container 50, it is very easy to discard dust.

When forgetting to mount the dust collecting container 50 to the dust collecting container chamber 21 of the cleaner main body 11, the suction opening 24 of the electric blower 23 and the dust collecting container chamber 21 of the vacuum cleaner main body 11 Direct communication through the guide channel (G). In this state, when the switch 13a of the operation part 13A of the handle operation pipe 13 is operated, the electric blower 23 is driven and the dust collection chamber 21 is negatively pressured.

By this negative pressure, as shown in FIG. 4, the button 42 of the cover 40 is pushed down against the pressing force of a spring (not shown), and the hole 41 of the cover 40 is removed. Open. As a result, outside air is introduced directly into the dust collecting container chamber 21 of the cleaner body 11 through the hole 41, so that almost no air is sucked from the suction inlet 15 operated on the surface to be cleaned where a lot of dust exists. do. That is, dust is sucked out of the suction port 15.

For this reason, the problem that the dust suctioned from the suction port 15 is sucked directly in the electric blower 23 can be prevented. In addition, when a secondary filter (not shown) is provided upstream of the electric blower 23, the secondary filter is prevented from being immediately blocked. Further, it is possible to prevent a problem that the suction port 15 sucks hard foreign matter, and the foreign matter tears the secondary filter and is sucked into the electric blower 23 to damage the electric blower 23.

Furthermore, when the dust collecting container 50 is not mounted, the inside of the dust collecting container chamber 21 is directly communicated with the outside air through the hole 41 provided in the cover 40, so that the dust collecting container 50 is not installed. Even if it is, the cover 40 can be closed, and it is convenient in carrying out, for example.

Furthermore, the structure of the vacuum cleaner main body 11 is simplified by using the hole 41 which penetrates the operation button 42 for dust compression as a hole for introducing external air into the dust collection container chamber 21.

In addition, since the extruded plate 100 may be removed from the rods 104 and 104, the extruded plate 100 may clean dust or the like that has entered the extruded plate 100.

24 illustrates a portion of a dust collecting container 150 of another example. The dust collecting container 150 is rotated around the shaft 201 to the position indicated by the dashed line by the interlocking mechanism 70. In addition, the filter F2 is formed in an arc shape so that the vibration damping mechanism, that is, the blade 107 comes into contact with the filter surface F2a of the filter F2 when the extrusion plate 200 is rotated. At the same time, the dust of the dust collecting chamber part 55 is extruded to the extrusion plate 200. 202 is an opening.

By the way, the button 42 of the lid 40 moves downward due to the negative pressure of the dust collecting chamber 21 to open the hole 41, but the pressure of the spring (not shown) that presses the button 42 is reduced. By setting the size to a predetermined value, the button 42 can be vibrated up and down when the outside air flows through the hole 41. The notification sound may be generated by the vibration of the button 42. In this case, the button 42 and the spring constitute a notification mechanism.

In addition, by allowing the outside air to pass through the hole 41, a vibrating member or a warning member that vibrates to generate a sound may be provided in the hole 41 to warn the user of forgetting to mount the dust collecting containers 50 and 150.

In the said embodiment, although the dust of the dust collecting chamber part 55 is extruded from the extruded plates 100 and 200, it is not necessary to extrude dust. That is, the extruded plates 100 and 200 may be used to remove dust adhered to the filter F1 from the blade 107. In this case, the damping mechanism is constituted by the extruded plate 100 (200), the blade 107, and the interlock mechanism 70.

In this case, the button 42 is a dedicated button for operating the vibration suppression mechanism.

According to the present invention, even if the electric blower is driven while the dust collecting container is not installed, it is possible to stop the suction of the dust from the suction inlet body, thereby preventing the dust from being sucked into the dust collecting chamber or the electric blower. have.

In addition, in the present invention, even when the dust collecting container is not mounted, the cover of the dust collecting container chamber can be closed to transport the cleaner body, and when the carton or the dust collecting bag is not installed, the cover of the dust collecting container chamber is closed or the cleaner body cannot be set. The configuration differs from the techniques disclosed in Japanese Unexamined Patent Publications Nos. 1-291821 and 3297224. Moreover, according to this invention, when a dust collecting container is not installed, it is the structure which introduces external air to the dust collection container chamber by the drive of an electric blower, and the structure disclosed by patent publication 11-9526 which introduces outside air when it is clogged with dust; Is also different.

The present invention is not limited to the above embodiments, and various modifications and changes can be applied to these embodiments.

For example, in the above embodiment, the opening and closing member always closes the hole by the pressing force of a spring (not shown) regardless of whether the dust collecting container 50 is attached to the dust collecting container chamber 21, but the dust collecting container is mounted in the dust collecting container chamber. In this case, when the opening / closing member closes the hole and the dust collecting container is not mounted in the dust collecting container chamber, the opening / closing member may be configured to individualize the hole.

According to the present invention, even if the electric blower is driven without forgetting to attach the dust collecting container to the cleaner main body, it is possible to prevent dust from being sucked in from the suction port body. Further, for example, even if the dust collecting container is not inserted into the main body, the lid of the dust collecting container chamber can be closed, and therefore, the cleaner main body can be transported.
