Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized vacuum cleaner called a handy type.

[0002]

2. Description of the Related Art In this type of vacuum cleaner, as shown in FIG. 5, a main body 21 made of synthetic resin is formed by being divided into right and left parts, and a main body right half 21a and a main body left half formed in this manner. The part 21b is assembled by incorporating components such as the blower 24 and the motor 25 into the inside and connecting them by means such as screws. Then, the recess 23 formed on the front side of the main body 21 is airtightly closed by the lid 22 with the packing 27 interposed therebetween, thereby forming a dust collection chamber therein. Thus, in this type of small vacuum cleaner, the right half 21 of the main body constituting the outer shape of the main body 21 is provided.
a and the left half portion 21b of the main body are simultaneously formed with the concave portion 23 serving as a dust collecting chamber, so that it is necessary to prevent air leakage from the joint portion and reduce the suction power. was there.

Therefore, conventionally, at the time of assembling, a liquid sealant is applied to the joint surface 29 between the right half part 21a and the left half part 21b of the main body in advance, or a packing ( (Not shown)), and the two are connected with a packing interposed therebetween.

In the vacuum cleaner having the above-described structure, the inside of the dust collecting chamber is hollow and has no structural material, so that the strength of this portion of the main body 21 is low. Since the internal air is sucked by the blower 24 and becomes negative pressure, there is a possibility that the air is deformed. Therefore, in the conventional vacuum cleaner, as shown in FIGS. 5 and 6, a reinforcing rib 28 is provided on the inner surface of the main body 21 at a location corresponding to the dust collecting chamber.

[0005]

In the conventional vacuum cleaner described above, when joining the main body formed separately on the left and right, a liquid sealant or packing is used to prevent air leakage from the joint. In order to prevent air leakage, it is necessary to take measures to prevent air leakage. Also, if a liquid sealant is used as a measure to prevent air leakage, careful care must be taken to ensure that the liquid sealant does not protrude from the joint surface during assembly. Since the sealing property is deteriorated, it is necessary to reseal again, and there is a problem that not only the assembling workability is poor, but also maintenance such as inspection and repair requires trouble.

Further, in the above-mentioned vacuum cleaner, since the dust collecting chamber is formed directly inside the main body, if a crack occurs in the main body due to careless handling or the like, air leaks from the main body, and suction is performed. There was a problem that the basic function of the vacuum cleaner was adversely affected, such as a decrease in the power rate.

Furthermore, in the above-mentioned vacuum cleaner, since the ribs are provided on the inner surface of the dust collecting chamber, the paper bag for dust collection may rub against the ribs during operation and break. Later, even when the filled paper bag is taken out of the dust collection chamber, the paper bag is caught by the ribs, and there is a problem that the operation is difficult to perform.

An object of the present invention is to solve the problems of the above-mentioned conventional vacuum cleaner.

[0009]

According to the present invention, in order to solve the above-mentioned problems, an electric machine in which a main body, which is a synthetic resin molded product, is joined to a main body right half and a main body left half so that the main body can be assembled. In a vacuum cleaner, an open-top case having an air supply port on the front side and an exhaust port on the back side in a recess formed between the suction port of the main body and the blower provided in the main body. The dust collecting chamber is formed by airtightly closing the upper surface of the case with a lid engaged with the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment illustrating the present invention.

FIG. 1 is a simplified exploded perspective view of a vacuum cleaner according to the present invention, and FIG. 2 is a perspective view of an assembled state thereof. As shown in the drawing, in this vacuum cleaner, the main body 1 is formed by being divided into right and left parts, as in a conventional handy type, and is assembled by integrally joining the main bodies. Further, the recess 10 of the main body 1 assembled in this manner is covered with a detachable lid 2, and the interior is formed as a dust collection chamber in the same manner as the conventional one.

Here, in the present invention, a case 3 formed of a synthetic resin in a predetermined shape is sandwiched between the right body half 1a and the body left half 1b which are integrally joined. The case 3 is located in a recess 10 formed between the suction port 6 of the main body 1 and the blower 4 provided in the main body 1, and the upper surface is hermetically closed by the lid 2.
This forms a dust collection chamber in which the airflow is guided in the front-back direction.

The case 3 is formed in a box shape having an open upper surface by integral molding of a synthetic resin, and has an air supply port 3a on a front surface and an exhaust port 3b on a rear surface. Further, a lid 2 is provided on the upper peripheral edge 3c of the case 3.
And a frame-shaped packing 11 for keeping airtightness between them.

FIG. 3 is a side view of the vacuum cleaner assembled as described above, and FIG. 4 is a sectional view taken along line AA.
As shown in the drawing, in the vacuum cleaner of the present invention, the ribs 8 protruding from the inner surface of the main body 1 abut against the ribs 9 protruding from the outside of the case 3 to position and hold the case 3 at a predetermined position. The projections such as ribs are not provided on the inner surface of the case 3 constituting the dust collecting chamber.

In FIG. 4, reference numeral 7 denotes a filter provided in front of the blower 4. This filter 7
It may be provided behind the exhaust port 3b of the case 3, or may be directly attached to the exhaust port 3b.

The vacuum cleaner of the present invention having the above configuration has
The right half 1a of the main body and the left half 1b of the main body incorporate components such as the blower 4 and the motor 5 therein, and after arranging the case 3 at a predetermined position, are connected by means such as screws. To assemble. As a result, the case 3 is such that the air supply port 3 a provided on the front surface (the left front side in FIG. 1) is located behind the suction port 6 of the main body 1, and
Exhaust port 3b provided on the back (right rear side in FIG. 1)
Is inserted into the main body 1 so as to be located in front of the blower 4 housed in the main body 1. At this time, in the vacuum cleaner of the present invention, it is not necessary to take measures to prevent air leakage on the joint surface of the main body 1 using packing or a liquid sealant.

After assembling the main body 1 in this manner,
When a paper bag (not shown) for dust collection is loaded at a predetermined position in the case 3, the lid 2 is engaged with the main body 1 so as to cover the upper surface of the case 3, and the cover is provided at the upper end of the case 3. The upper surface of the case 3 is hermetically closed by the packing 11 being in close contact with the back surface of the lid 2 to form a dust collection chamber that is closed in a direction other than the direction in which the airflow occurs (the left-right direction in FIG. 3). is there.
Therefore, when the motor 5 is started and the blower 4 is operated in this state, the air sucked from the suction port 6 generates an airflow moving in the front-rear direction in the case 3, and the dust sucked together with the air is removed from the case 3. After being caught in a paper bag loaded in the case 3, it is sucked out from the back of the case 3 and
At the right).

As described above, the vacuum cleaner of the present invention can be used without any difference from the conventional one. When the paper bag for dust collection is full, the lid 2 is removed and the paper bag is taken out of the dust collection chamber for disposal. At this time, in the vacuum cleaner of the present invention, the collection is performed as described above. Since there are no protrusions such as ribs on the inner surface of the case 3 serving as a dust chamber, the paper bag can be easily taken out without being caught by the paper bag. This also prevents the paper bags from rubbing and breaking during operation of the vacuum cleaner.

[0019]

As described above, in the vacuum cleaner of the present invention, since the case constituting the dust collection chamber is provided inside the main body, air such as packing or liquid sealant is provided on the joint surface of the main body. There is no need to provide leakage prevention means. Therefore,
The efficiency of the assembling work can be improved, and it can be easily disassembled and reassembled, and the maintainability of repair and inspection can be improved.

Even if the main body made of synthetic resin is cracked by dropping, the airtightness in the dust collecting chamber is still
Since it is kept in the inner case, it has no effect on the function of the vacuum cleaner itself. Therefore, the durability and operation reliability of the vacuum cleaner are improved.

Further, since there are no protrusions such as ribs on the inner surface of the case constituting the dust collection chamber, taking in and out of the paper bag for dust collection is not hindered, handling is improved, and the paper bags rub against each other during operation. There is no danger of breaking.
