Description

[Detailed description of the invention] Industrial application field This invention is a hose connected to an upper lid that covers a dust collection chamber from above, and is inserted and connected so that it can rotate freely about the normal line to the connection surface as the axis of rotation. It has a hose connection device that allows you to cover a wide cleaning area by rotating the hose.
This relates to a vacuum cleaner that is easy to clean and operate.

BACKGROUND ART As shown in FIGS. 7 to 11, in a conventional vacuum cleaner 1 of this type, a hose connection rotating body 2 is connected to a top surface 4 formed substantially parallel to the floor surface of the top lid 3. It was disposed between inner lids 5 that were fixed from the inside, and was rotatably held.

The hose connection rotating body 2 has a hook part 9 that engages with a buckle 8 provided on a connection pipe 7 to which a hose 6 is fixed.
an intake port 10 with a screw 1 in the intake port 10;
1, a packing 13 for air tightness held between the intake port 10 and the mounting plate 12, and a packing 14 held by the mounting plate 12 to perform air tightness between the inner lid 5. , a rail 15 and a rail 16 wrapped around the side surface of the mounting plate 12, a connecting terminal 17 electrically connected to the rails 15 and 16 and held on the mounting plate 12, and a connecting terminal 1.
It consists of 8. Reference numeral 19 denotes a pipe terminal 19 provided on the connecting pipe 7 opposite to the connecting terminal 17.
20 is a pipe terminal 20 provided in the same manner.

The connection terminals 17 and 18 are rail terminals A22 fixed to the backing plate 21 so that when the connection pipe 7 is connected to the hose connection rotating body 2, they come into contact with a hand switch (not shown) on the opposite side of the hose 6 and the rail 15. , serves to connect to the electric circuit of the motor of the vacuum cleaner body via the lead wire A23.

Problems to be Solved by the Invention However, in such conventional vacuum cleaners, the connection terminals 17 and 18 must be fixed to the bosses and connected to the rails 15 and 16 using lead wires, as shown in FIG. As a result, assembly is extremely troublesome, and connecting the lead wires takes time, resulting in high assembly costs.

The present invention solves these conventional problems and provides a vacuum cleaner structure that requires no effort to assemble.

Means for Solving the Problems The technical means of the present invention for solving the above problems consists of a main body case with a built-in electric blower and a dust collection chamber formed on the suction side, and an upper part of the dust collection chamber. It is inserted into the top lid that opens and closes, and the suction port of this top lid.
and a connecting pipe provided at one end of the hose, the connecting pipe being connected to a freely rotatable hose connecting rotating body provided at the suction port of the upper cover, and each of the hose connecting rotating bodies having a circular ring shape. A connecting terminal, the lower end of which is connected to a conductive rail provided on the lower surface of the lower rotating body, is clamped and fixed between the upper and lower rotating bodies, and the connecting terminal is further connected to the connecting terminal. The upper end is bent inward and connected to a hose terminal provided on the connecting pipe.

Function The present invention simplifies the connection between the rail and the connecting terminal and facilitates assembly using the above-described configuration.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 to 6, 21 is the main body case of the vacuum cleaner, which is divided into two parts, front and rear.The rear side houses an electric blower, cord winding device (not shown), etc., and the front side houses a hose. 22, an extension pipe, and a dust collection chamber 24 housing a paper bag 23 for collecting and depositing dust sucked in through a floor nozzle (not shown). 25 is a pair of rear wheels attached to both sides of the rear end of the main body case 21, and 26 is a swivel wheel device attached to the back of the bottom of the dust collection chamber 24, both of which facilitate movement of the main body of the vacuum cleaner during use. I have to.

27 is a rear lid attached to cover the rear upper part of the main body case 21; 28 is an upper lid that is pivotally fixed to the rear lid 27 and covers the dust collection chamber 24 from above in a manner that can be opened and closed; A substantially circular opening 30 is formed in the opening 30 . Reference numeral 31 denotes an inner lid fixed to the upper lid 28 from the dust collection chamber 24 side, and a gasket 32 is attached at a position facing the opening 30.

33 is a hose connection rotary body facing the opening 30 and rotatably and slidably held between the upper cover 28 and the inner cover 31;
The lower hose connection rotor 35 is composed of two parts 5.
An inner rail 36 and an outer rail 37 are attached to the bottom surface. 38 are two pairs of connection terminals, which are provided at 180° symmetrical positions around the rotation axis, and are connected to the inner rail 3.
6. They are in contact with the outer rail 37 and are electrically conductive. 39 is held between the upper hose connection rotor 34 and the lower hose connection rotor 35 together with the packing and connection terminal 38, and is fastened and fixed with a screw 40. The inside of the packing 39 maintains airtightness with the hose pipe 41 when inserted, and the outer periphery provides air tightness with the inner lid 31. 42 and 43 are rail terminals that contact the inner rail 36 and the outer rail 37, respectively, when attached to the upper lid 28, and lead wires 44 and 45 are spot-welded to the electric circuit ( (not shown).

Reference numeral 46 denotes a connecting pipe divided into left and right sides, which holds the hose pipe 41, the hose 22, and the hose buckle 47. A pair of hose buckles are provided 180° apart. 48 is connecting pipe 4
6 is a hose terminal that contacts the connection terminal 37 and becomes electrically conductive when it is inserted into the rotary plate 33 and connected.
They are arranged as a pair at positions facing each other, and are connected to the piano wire in the hose 22 by a lead wire C49 and a lead wire D50, and are electrically connected to a hand switch that remotely controls the operation of the electric blower. Here, the connecting pipe 46 has a hose buckle 47 and a hose terminal 48.
are alternately shifted by 90 degrees. In addition, the hose terminal 48 extends in the front and back direction of the connection pipe 46.
It is formed into a long and narrow shape.

Next, 51 is a hook portion provided on the rotary plate 33 that faces the hose buckle 47, and 52 is a terminal hole that exposes the connection terminal 37 to the outside and faces the hose terminal 48.

Next, the operation of this configuration will be explained.

When the user inserts the connecting pipe 46 into the rotary plate 33, not only are two hose buckles 47 provided in each pair, but also two hose terminals 48 are provided in each pair, shifted by 180 degrees. Since there are two holes each for the hook portion 51 and the terminal hole 52 provided on the rotary plate 33, the terminal can be easily inserted. At this time, even in the worst case, for example, if the hose terminal 48 is applied to the hooking portion 51, it can be inserted and attached by simply twisting the connecting pipe 46 by 90 degrees, making it highly usable.

Furthermore, since the hose terminal 48 has an elongated shape in the front and back, the terminal hole 5 provided in the rotary plate 33
2 can also be formed to be very small in width compared to the hanging portion 51. Therefore, when inserting the connecting pipe 46, it is easy to distinguish the direction in which the hose buckle 47 and the hose terminal 48 are inserted, and the insertion is further facilitated.

In addition, since the hose buckle 48 is provided in two places, even if the hose 22 is pulled strongly, there is little rattling between the connecting pipe 46 and the rotary plate 33.
The connecting pipe 46 can continue to rotate smoothly, improving operability.

Effects of the Invention As described above, according to the present invention, a rail is provided on the bottom of the hose connection rotor, a connection terminal is provided above the rail, and the connection terminal is held between the upper and lower hose connection rotors, which are divided into upper and lower halves. Since the parts are assembled together, it is easier to assemble, and there is no need to connect lead wires, resulting in lower costs.
