Abstract

PURPOSE:To improve operability by providing a bent pipe between the cleaner body side movable hose and the suction port side extension pipe and receiving a control section in a handle-shaped bent case molded integrally with the upper side of the bent pipe, opened in the upper surface and covered with a cover member to form a handle section. CONSTITUTION:A bent pipe 7 having a bent part 8 on the tip is connected between the cleaner body side movable hose 4 and an end of the suction port side extension pipe. A handle-shaped bent case 8' having an opening on the upper surface is molded integrally with the upper side of the bent pipe 7. A control section 9 for a motor fan in a main body is received in the handle- shaped case 8'. The control section 9 is formed of a control substrate 11 connected to a steel wire 6 of the hose 10 through a lead wire 10 and an operating lever 12 for operating a variable resistor 13 mounted on the substrate 11. The opening in the handle-shaped case 8' is covered with a cover member 14. The operating lever 12 is operated by an operating part 21 slidable along a guide groove 21 to control the motor fan, so that the assemblage can be efficiently carried out and the operability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner constructed by connecting a floor suction port or the like to a cleaner body through a flexible hose and an extension tube.

[0002]

2. Description of the Related Art Conventional electric vacuum cleaners of this type include, for example, Japanese Utility Model Publication No. 57-166856 and Japanese Utility Model Publication No. 42-122.
There is publication 78. The former is one in which a separate handle is clamped and fixed to the bent portion of the extension pipe. In the latter, the grip handle tube is rotatably fitted in a connection tube inserted into a flexible hose, and a remote switch is provided between the connection tube and the grip handle tube.

[0003]

However, in the above-mentioned prior art, in the former case, since the extension tube and the handle body are separate bodies, the assemblability is poor, and the handle body to which force is applied is separate from the extension tube. Therefore, during cleaning work, squeaking may occur in this portion, or the fixing screw portion may be damaged.

In the latter case, the grip handle tube is formed to have a relatively large diameter because dust passes through the inside, and it is difficult for a woman with a small hand to grip it, and cleaning operability is poor.

[0005]

According to the present invention, a bent pipe for connecting an extension pipe is connected to an end of a flexible hose having a conductive wire connected to a cleaner body. A curved handle lower case with an upper opening is integrally formed on the upper surface side of the pipe, and the handle lower case houses a control unit for controlling an electric blower built in the cleaner body through the conductive wire. It is characterized in that it is covered with a member, and a handle portion is formed by the lower case of the handle and the cover member.

Further, the present invention is characterized in that the cover member is slidably provided with an operation portion of a control portion housed in a lower case of the handle.

[0007]

According to the present invention, even when the floor suction port is connected to the tip of the extension pipe, the handle portion of the connecting pipe provided at the end of the flexible hose is grasped to easily move the floor suction port. Can be done. Further, the handle portion is composed of a handle lower case having an upper opening formed integrally with the connecting pipe and a cover member covering the upper opening of the lower handle case, so that the control unit of the electric blower can be easily incorporated in the handle portion. Therefore, the assembly workability can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a cleaner body having a dust collecting part and an electric blower built therein, 2 is a floor suction port, which is connected to an upper surface side of the cleaner body 1 through an extension pipe 3 and a flexible hose 4. .. The flexible hose 4 has a pair of steel wires 6 and 6 spirally provided along the inner surface of the outer skin 5 and also serves as a conductive wire.

Reference numeral 7 is a bent pipe having a bent portion 8 at the end connected to the end portion of the flexible hose 4 for connecting the extension pipe 3, and the cross section of the bent pipe 8 is approximately U on the upper surface side. A curved lower handle case 8'having a letter shape is integrally formed, and a handle portion is constituted by the lower handle case 8'and a cover member 14 which will be described later. A control unit 9 for controlling the electric blower built in the main body 1 is housed. The control unit 9 uses the lead wire 1
A control board 11 having various electric parts connected to the steel wires 6 and 6 of the flexible hose 4 by means of 0 and 10 and a variable resistor 13 having an operating rod 12 mounted on the board. There is. Reference numeral 14 is a cover member for covering the lower case 8'of the handle. The cover member inserts and locks the tip projecting portion 15 into the locking hole portion 16 formed in the pipe 7, and the central portion covers. The member 14 and locking claws 17 and 18 projecting from the lower case 8'of the handle are engaged with each other, and the rear end is fixed to a boss portion 20 provided on the pipe 7 by a screw 19.

Reference numeral 21 denotes an operating portion of the variable resistor 13 which slides along guide grooves 22, 22 formed on the upper surface of the cover member 14 on its side surface, which operating portion is the operating rod 12 of the variable resistor 13. Connected with. Reference numeral 23 is a cylindrical cover for covering the connecting portion between the flexible hose 4 and the bent pipe 7, 24 is a main body insertion port of the flexible hose 4, and an intake air formed on the upper surface side of the cleaner main body 1 It is detachably connected to the mouth (not shown).

Therefore, in the state shown in FIG. 1, the handle portion of the bent pipe 7 connected to the end of the flexible hose 4 is grasped by hand, and the floor suction port 2 connected to the tip of the extension pipe 3 is held. Can be operated smoothly and the operation part 2 of the handle part
By operating 1 with the thumb, the steel wires 6, 6 of the flexible hose 4
The electric blower built in the cleaner body 1 can be easily controlled via the.

[0012]

As described above, according to the present invention, since the handle portion is formed by the handle lower case integrally formed with the bent pipe and the cover member that covers the upper opening of the handle lower case, the handle portion is gripped. In addition to being able to form a diameter that is easy to perform, it is possible to prevent the curved pipe and the handle portion from being displaced, and improve the cleaning operability. Further, the suction force can be easily adjusted at hand by the control unit provided in the handle portion, and the usability can be improved. Further, since the lower case of the handle is integrally formed with the bent pipe, it is possible to improve the assembling workability such as the work of incorporating the control unit in the handle unit and the work of connecting the control unit and the conductive wire of the flexible hose. There is an effect such as being able to.
