Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a
It is related to removing machine.

Conventional Shio Byproducts and Their Problems Conventionally, in vacuum cleaners with both cold and fractional exhaust, the Tsujitsuneka medium exhaust port is blocked by a valve body.
When used as a blower, the hose is placed between the outlet and the outlet, and the exhaust passage of the river is shut off with a valve body. In this case, the valve body has a rotating shaft, and this rotating shaft is rotatably held in a bearing hole formed in the main body case which is divided into two parts. In addition, in order to form the exhaust port part of the above-mentioned central exhaust port, a semicircular hole is formed in each of the two pieces of the main body case O, and when the hose tube pile a is inserted, this main body case O is divided into two parts. The case should not be pushed open further than the split part), and the fitting fee for insertion should be as much as possible.
When using the blower, hoses IXζ and 7 are disconnected.
As shown in A, the semi-circular hole is inserted into the main case from the outside 111i and the inside of the main case, and the exhaust port having an i11'; FIG. 9 shows this conventional example. 1a and 1b are false cases, 2
is the valve body, 3 is the central exhaust port, 4 is the square 1, 2 and the central D [spring 1, 5, which urges the direction where the air port 3 is blocked, the entire circumference of the air port 3. It is installed in the fC stand ζ11 (b 5
However, when assembling, the 2s of the action of planning and the action of inserting the valve body 2 gold. It was difficult to assemble the main body case 21a and 1b because it had to be done at the same time.
K. To form the fitting grooves 5 with the main body cases 1a and 1b, when trying to form a shadow on the part f by resin molding, the molding die is moved in the three directions of arrows C, d, and e as shown in Figure 810. This creates the need to move the mold, which results in a complicated mold construction, resulting in high mold costs.This is reflected in the unit price of the parts, resulting in the parts being expensive.

OBJECTS OF THE INVENTION The present invention solves these conventional problems, improves ease of assembly, improves workability of parts, and provides inexpensive parts.

Structure 1 of the Invention The present invention provides a common exhaust port with a bearing part, a locking protrusion, a recess, and a full role σ, and a shaft part formed on a valve body in the bearing part, which is layered so as to be able to be excited. The protrusion is placed on the mating surface of the main body case, and the recess is fully engaged with the claw provided at the clamping part of the air exhaust port of the main body case, so that the main body case of the air mouthpiece is bent down. Out.

Therefore, when assembling the main body, the valve body and the spring body are temporarily assembled to the central exhaust port and then installed inside the main body case, so the whole main body case is 1e1. When adjusting to t, the only sandwiched part is the central exhaust port, and it is assembled in 1). The shape of the concentrated fJI air port is such that it fits into the main body case with a locking protrusion provided on the central exhaust port, and a recess provided between them. Since the claw part provided on the II"E mouth clamping part is fitted, there is no need for a groove.
The direction of movement of the mold during resin molding can be parallel to the insertion direction of the hose connection pipe, which improves assemblability and parts workability.

DESCRIPTION OF EMBODIMENTS The main body case of a vacuum cleaner is divided into two parts along the center plane, and consists of a right case 6a and a left case 6b and K.

The main body case 6 is connected to a layer case 8 which has an intake lower part through a filter (not shown), and an electric blower 9 and a winding cord winding device 1.0 are housed inside. There are nine. And below the main body case 6 is a moving rear wheel 11.
However, a handle 12 is provided above, a front moving wheel 13 is provided below the dust collection case 8, and a handle portion 14 is provided above. It has become. Further, in a part of the exhaust passage at the rear of the main body case 6, a claw portion 17 for clamping the central exhaust port 16 and a hooking lip 19 for the coil spring 18 are provided on the main body case 6.
is integrally formed.

2o is a valve body, 21 is a bearing portion which is formed integrally with the above-mentioned central exhaust port 16 and has an opening toward the insertion direction of the hose connection pipe 22, and a rotation shaft 23 provided with the valve body 20iC.
are rotatably fitted.

24 is a mounting seat for the coil spring 18. The hose connection pipe 22 is removably fitted into the hole 25 of the central exhaust 016. -26 is a distributed exhaust port, 27 is an exhaust filter, 28 is a concentrated 4. The concave portion formed in the II' air port 16 fits into the claw portion 17 of the main body case 6. 29! 'i,
4, the appropriate protrusion formed in the exhaust port 1e3 allows the above-mentioned recess 28
is the li:il K central exhaust port 16 of this locking protrusion 29.
is formed along the outer periphery of the

Note that the locking protrusion 29 is formed so as to come into contact with the inner wall I of the main body case 6.

To explain the operation in the above configuration: *2 L2J
As shown in the figure, during the normal suction operation of a vacuum cleaner, the exhaust gas flows as shown by the arrow f, passes through the i-no-1 air filter 27 to the outside of the main body case 6, and is discharged from the dispersion exhaust port 26. now,
When used as a blower, as shown in FIG. It is something that At this time, the exhaust gas is prevented from flowing toward the distributed exhaust port 26 by the valve body 2o and deflects. Note that if the hose readout tube 22 is completely removed, the valve body 20 will return to its original state as shown in FIG.
ID is restored, and the hole 25 of the central exhaust port 16 is 1=Ki.

When assembling this vacuum cleaner, first compress the coil spring 18, insert it into the coil spring mounting seat 24 of the valve body 20, and assemble it into the valve body 20. As shown in FIG. 5, the rotating shaft 23 is inserted through the opening of the bearing portion 21 of the central exhaust port 16. In this state, it is temporarily assembled, and as shown in Figure 6, for example, the i-body case 6,
Right case 6aK First, insert the above temporarily assembled parts so that the locking protrusion 29 of the central exhaust port 16 comes into contact with the inner wall surface of the right case 6a, and then insert the claw portion 1γ of the right case 6a into the central exhaust port 1. If the coil springs 18 are fitted into the recesses 28 and the coil springs 18 are hooked onto the hooking ribs 19, then the left case 6bf is simply placed over the right case 6a and joined together to complete the assembly into the main body. At this time, due to the bias of the coil spring 18, the rotation shaft 23 of the valve body 2Q is usually held in a compressed manner by the bearing portion 21 of the central exhaust port 16 so as to be rotatable.

In addition, when molding the central exhaust port 16 with resin in this embodiment, the direction of movement of the mold is as shown in FIG.
Since the component can be extracted simply by moving parallel to the insertion direction of 2, the mold structure can be made simpler than the conventional example.

Effects of the Invention As described above, the valve body mounting device of the present invention has good assemblability without assembling multiple fitting parts at the same time when the main body is standing. )The molded product can be pulled out in one direction during fat molding. However, the mold structure is simple, and therefore the mold cost is low (4:4ii), and the mold cost is less reflected in the part unit price, making it possible to provide low-cost parts. It is something.
