Description

Description: TECHNICAL FIELD The present invention relates to an electric vacuum cleaner in which a hose is provided with a grip portion for connecting a suction member provided with an electric load.

(Prior Art) Conventionally, an electric vacuum cleaner which mechanically and electrically detachably connects a cleaner body, a hose, and a suction member composed of an extension tube and a suction port body is shown in, for example, FIG. As shown in the drawing, a configuration is known in which a hose is provided with a conductive wire in order to supply electric power from a cleaner body to an electric motor that is an electrical load that drives a rotating brush provided in a suction port body.

The electric vacuum cleaner shown in FIG. 9 has a flexible hose body 4 which is connected to an extension pipe and which holds a grip pipe 3 which is gripped during cleaning.
The grip portion 2 of the hose 1 is formed so as not to rotate. That is, the conducting wire 5 embedded in the hose body 4 as a conductive means is connected to the conducting wire 7 housed between the grip tube 3 and the cover body 6 fixed to the outer peripheral surface of the grip tube 3, and this conducting wire is connected. Connector 8 provided at the tip of grip 3
Connected to. The connector 8 is detachably connected to the connector provided on the extension tube. Further, in the conducting wire 7 of the hose body 4, an operable switch 9 for turning on / off the electric motor of the suction port body is provided.

A variable resistor 11 for controlling the input of the electric blower in the cleaner body is operably provided between the grip pipe 3 of the hose 1 and the cover body 6, and the variable resistor 11 is connected to the hose. It is connected to a control circuit in the main body of the vacuum cleaner via a conductor 12 different from the conductor 7 for power supply embedded in the body 4.

However, in the vacuum cleaner having the conventional structure shown in FIG. 9, since the grip 3 of the hose 1 is not rotatable, during cleaning, the positional relationship between the cleaner body and the hose 1 may cause a change. The hose 1 is twisted and there is a problem in operability.

Therefore, it is conceivable that the grip of the hose is configured by rotatably connecting the grip pipe to a connection pipe fixed to the hose body. With this configuration, if the grip pipe rotates too much, the connection pipe There is a risk that the conducting wire led from the to the grip tube may wind around the grip tube, resulting in damage or disconnection.

Further, conventionally, as a suction port body provided with an electric motor supplied from the vacuum cleaner body, for example, the configuration described in Japanese Utility Model Laid-Open No. 62-43552, that is, rotatable to an introduction pipe connected to the suction port body. Of the suction pipe, which is connected to the extension pipe and is connected to the extension pipe, is formed by an arcuate notch groove formed in the introduction pipe and an engagement protrusion that is formed in the suction pipe and engages with the notch groove. There is known a structure in which the wire is regulated within a certain angle to prevent the conducting wire from being wrapped around the pipe.

However, in the suction port body of the electric vacuum cleaner described in Japanese Utility Model Laid-Open No. 62-43552, even if the rotatable range of the grip tube of the hose is restricted, first, the limit of the range in which the grip tube can rotate etc. If it is located at the limit in the clockwise direction, the grip tube cannot be further rotated in the clockwise direction with respect to the connecting tube, and the twisting of the hose body is prevented from rotating in the clockwise direction. There is a problem that cannot be done.

(Problems to be Solved by the Invention) As described above, the ninth aspect of electrically connecting the electric circuit of the cleaner body and the electric load of the suction port body through the lead wire of the hose.
In the conventional electric vacuum cleaner shown in the figure, since the grip of the hose cannot rotate, the hose is twisted during cleaning, and there is a problem in operability. Further, even if the grip tube is made rotatable, there is a problem that the conductor wire is twisted and broken when the grip tube is excessively rotated. In addition, a real Kaisho equipped with rotation control means
Even in the vacuum cleaner described in Japanese Patent No. 62-43552, if the grip tube is located at the limit of the rotation range at the beginning, there is a problem that the twist of the hose body cannot be prevented against the rotation in the regulated direction. Occurs.

In view of the above problems, it is an object of the present invention to provide an electric vacuum cleaner that reliably prevents twisting of a hose during cleaning, is easy to use, and prevents damage to the lead wire of the hose.

(Means for Solving the Problems) An electric vacuum cleaner according to the present invention has a dust collecting chamber inside which an electric blower is built in and communicates with an intake side of the electric blower, and the dust collecting chamber communicates with the outside.

Thus, an elastic body for urging the grip pipe is provided with respect to the connection pipe.

(Operation) In the electric vacuum cleaner of the present invention, when the grip tube at the other end of the hose whose one end is connected to the cleaner body is gripped for cleaning, the hose is moved by the change in the positional relationship between the cleaner body and the hose. Even if the grip pipe is displaced or rotated in the twisting direction, the grip pipe rotates with respect to the connection pipe fixed to the hose body, so twisting of the flexible hose body is prevented, and the connection pipe and the grip pipe are prevented. The electrical circuit of the vacuum cleaner body and the electrical load of the suction member connected to the grip tube of the hose are electrically connected through the lead wire of the hose that is directly led from the connection tube side to the grip tube side, regardless of the positional relationship with The connection is kept. In addition, since the protrusion is provided with a stopper that abuts from the rotating circumferential direction to prevent the grip tube from rotating, the hose conductor wire is prevented from wrapping around the connection part between the connection tube and the grip tube, preventing damage to the conductor wire. And the elastic body

The joint pipe 84 is provided with a plug 85 electrically and detachably connected to the connector 78 of the extension pipe 76. Further, as shown in FIG. 7, a rotary brush 86 is rotatably supported in the suction port body 81 so as to face the dust suction port, and an electric motor as an electric load for rotationally driving the rotary brush 86. 87 are provided. That is, this electric motor 87
A belt 91 for rotation transmission is wound around a pulley 89 fixed to a rotating shaft 88 and a pulley 90 fixed to a rotating brush 86. And the electric motor 87 and the plug 85 of the joint pipe 84 are
It is electrically connected via a conductor 92.

Next, the operation of the above embodiment will be described.

At the time of cleaning, connect the insertion tube 33 of the hose 31 to the suction port 24 of the cleaner main body 21, connect the base end of the extension tube 76 to the grip tube 43 of the hose 31, and suck the tip end of the extension tube 76. Joint pipe of mouth 81
Connect 84.

In this state, through the low-voltage connector 25 and the low-pressure plug between the cleaner body 21 and the hose 31 and the low-voltage conductor 37 in the hose 31, the control circuit in the cleaner body 21 and the grip portion 41 of the hose 31 can be changed. The resistor 57 is electrically connected. In addition, the high-voltage connector 26 and the high-voltage plug 36 between the cleaner body 21 and the hose 31, the high-voltage conductor 38 in the hose 31, the conductors 65a, 65b,
65c, a connector 66 and a plug 77 between the hose 31 and the extension pipe 76, a lead wire inside the extension pipe 76, a connector 78 and a plug 85 between the extension pipe 76 and the suction inlet body 81, and a lead wire 92 at the suction inlet body 81. The electric motor 87 in the suction port body 81 is electrically connected to the power supply circuit connected to the AC power supply via the power cord 22 in the cleaner body 21 via the.

Then, the user grips the grip tube 43 of the hose 31 and moves the suction port body 81 on the surface to be cleaned, but the suction port body that is supplied with power from the cleaner body 21 through the hose 31 and the extension pipe 76. The rotating brush 87 that is rotated by the drive of the electric motor 87 of 81 scrapes out dust from the carpet or the like. In addition, the suction port body 81 is generated by the air flow generated by driving the electric blower in the cleaner body 21.
Dust sucked from the dust inlet of the
And it is guided to the dust collecting chamber of the cleaner body 21 through the hose 31 and is stored in the dust collecting chamber.

At this time, the user may use the grip portion of the hose 31 as needed.
By operating the slide switch 62 of 41, the electric motor 87 of the suction port body 81 can be turned on / off. Also,
By operating the control operator 59 of the same grip portion 41 to slide the slider 60 of the variable resistor 57, the resistance value of the variable resistor 57 is changed, and a control signal output to the control circuit. And the suction force can be adjusted according to the input of the electric blower, or the electric blower can be turned on and off.

Further, during cleaning, even if the positional relationship between the cleaner body 21 and the hose 31 is changed and the grip tube 43 is displaced or rotated in the direction in which the hose 31 is twisted, the grip tube 43 is fixed to the hose body 32. By rotating with respect to the connection pipe 42, the hose body
32 does not twist. Therefore, the operability during cleaning becomes very excellent.

At this time, since the high-voltage conductor 38 and the slide switch 6 on the side of the connecting pipe 42 of the hose 31 and the connector 66 of the grip pipe 43 are directly connected by the conductors 65b and 65c having no contact part in the middle, Even if the pipe 43 rotates, the electrical connection between the power supply circuit of the cleaner body 21 and the electric motor 87 of the suction port body 81 continues to be maintained.

Further, when the grip pipe 43 is rotated, the guide groove of the grip pipe 43 is
The stopper portion 50 of the valve 49 closely opposes the retaining projection 47 of the connecting pipe 42 in the rotation direction via the springs 51 and 52, whereby the rotatable range of the grip pipe 43 is restricted to less than 360 °. There is. For this reason, since the grip pipe 43 does not rotate in the same direction many times, the conducting wires 65b and 65c led from the connection pipe 42 to the grip pipe 43 are not excessively wound around the grip pipe 43 or the like. Absent. Therefore, it is possible to prevent the conductor wires 65b and 65c from kinking, and the grip tube 43 is provided by a margin of the length of the conductor wires 65b and 65c.
Since the electric wire rotates, excessive tension is not applied to the conductive wires 65b and 65c, and damage such as breakage or disconnection of the conductive wires 65b and 65c can be prevented. Further, the rotatability of the grip tube 43 does not decrease.

Further, in the state where no external force is applied, the grip tube 43 is in a rotatable range in which the stopper portion 50 faces the retaining projection 47 with the shaft center of the grip tube 43 interposed by the biasing force of the springs 51 and 52. Since it is located near the center of the
Even if the grip tube 43 receives an external force in either the clockwise or counterclockwise direction after gripping the grip tube 43,
The 43 can rotate at least about 180 °. Also, during cleaning,
Normally, the control operator 59 is directed upward and the tip of the grip tube 43 is directed downward, so that when the direction of the suction port body 81 is changed, the grip tube 43 is near the center of the rotatable range. Since the grip tube 43 is located at about 180 ° in both directions, the operability of the springs 51, 52 is less likely to be felt. When connecting the extension pipe 76 or the like to the tip of the grip pipe 43, the tip of the grip pipe 43 always faces the same direction with respect to the hose body 32 and the connection pipe 42. Cheap.

According to the above configuration, since the stopper portion 50 is provided in the guide groove 49 with which the retaining projection 47 for retaining the connection pipe 42 and the grip pipe 43 is slidably engaged, the grip pipe 43 can be rotated. Since the range is restricted, there is no need to use a new part to restrict the rotation of the grip tube 43, and the structure is lean, the structure can be simplified, the productivity can be improved, and the cost can be reduced.

Further, since the sliding contact portion is not interposed in the conducting wires 65b, 65c between the connecting pipe 42 and the grip pipe 43 which are rotatably connected as described above, not only the structure is simplified, but also
It is possible to prevent the contact property of the sliding contact portion from being deteriorated due to the adhesion of dust or the like, and it is possible to prevent electrical connection failure.

The grip pipe 43 of the hose 31 and the joint pipe 84 of the suction port body 81 can be directly and detachably connected without the extension pipe 76. In this case, the joint pipe 84 is connected to the connector 66 of the grip pipe 43.
The plug 85 is electrically connected. That is, in the usage pattern, the suction member may be one in which the extension pipe 76 and the suction port body 81 are connected, or may be only the suction port body 81. Further, two or more extension pipes 76 can be connected.

Next, another embodiment of the present invention will be described with reference to FIG.

The embodiment shown in FIG. 8 is applied not only to the rearmost end portion of the sliding contact portion between the connecting pipe 42 and the grip pipe 43 of the hose 31 of the embodiment shown in FIGS. Annular seal member
97 is provided. This seal member 97 is, like the seal member 55 at the rearmost end, fitted and held in an annular groove 98 formed on the outer peripheral surface of the grip tube 43 and is slidable on the inner peripheral surface of the connection tube 42. And it is closely attached.

According to the structure of the embodiment shown in FIG. 8, it is possible to prevent dust from entering the sliding contact portion between the connection pipe 42 and the grip pipe 43 from both outside and inside of the hose 31. Therefore, it is possible to more reliably prevent a decrease in the rotatability of the grip tube 43. Also,
Airtightness can be more reliably maintained at the sliding contact portion between the connection pipe 42 and the grip pipe 43, and the suction performance can be further improved.

The embodiment and the eighth embodiment shown in FIGS.
In the illustrated embodiment, the electric load provided on the suction port body 81 is described as the electric motor 87 for driving the rotary brush 86, but the electric load is not limited to the electric motor 87, and the It may be a sensor or the like for detecting the type and automatically controlling the input of the electric blower. In particular, when an electric load is used as a sensor, a small current flows in the conductors 65b, 65c of the hose 31, so that a sliding contact is provided between the connection pipe 42 and the grip pipe 43 that are rotatably connected. The lack of parts means
It is more effective in that it does not cause poor contact.

Further, the rotation preventing range of the grip tube 43 is regulated by the retaining projection 47 and the guide groove 49 for preventing the connection tube 42 and the grip tube 43 from coming off, so that the rotation regulating means and the retaining means are combined. However, both means may be separate.

Further, the elastic body for urging the grip pipe 43 against the connection pipe 42 is not limited to the coiled springs 51 and 52, but may be a leaf spring or the like.

(Effect of the Invention) According to the electric vacuum cleaner of the present invention, since the grip tube is rotatably connected to the connecting tube of the flexible hose body, the hose body is twisted when the grip tube is gripped and cleaned. Can be prevented and the usability at the time of cleaning can be improved.Since the conductor wire that electrically connects the electric circuit of the cleaner body and the electric load of the suction member is directly guided from the connection pipe side to the grip pipe side, the sliding contact part is Since the structure can be simplified without needing, electrical connection failure due to contact failure can be prevented, and the rotation of the grip tube is regulated by providing a stopper portion with which the projection abuts from the rotation circumferential direction.
The conductor can be prevented from being wrapped around the connection between the connection pipe and the grip pipe, and the conductor can be prevented from being damaged.The stopper part faces the protrusion with the shaft center of the grip pipe sandwiched when no external force is applied. The grip tube can be rotated in both directions, and twist of the hose body can be reliably prevented.
