Description

[Detailed description of the invention] Industrial applications The present invention relates to a vacuum cleaner.

Conventional technology Conventionally, vacuum cleaners include a general vacuum cleaner 1 that uses an AC power source as shown in Figure 5, and a vacuum cleaner 1 that has an internal storage battery and is charged from an AC power source as shown in Figure 6. There was a rechargeable vacuum cleaner 2. Fifth
The vacuum cleaner 1 shown in the figure has a main body 3, a hose 4, an extension pipe 5, and a floor suction port 6 connected to each other, and a cord 7 removably housed inside the main body 3 is pulled out and plugged into an outlet for power. In this state, the electric blower built into the main body 3 is operated to transfer the dust sucked in from the floor suction port 6 to the inside of the main body 3 and accumulate it.

The rechargeable vacuum cleaner 2 shown in FIG. 6 is composed of a main body 8 containing a storage battery and a DC electric blower, a dust collection ace 9, an extension pipe 10, and a floor suction port 11.
The battery is charged when not in use, and when it is used, it is easy to use without having to connect a cord like a regular vacuum cleaner.

Problems to be Solved by the Invention However, the general vacuum cleaner shown in Fig. 5 needs to be connected to a power source and cannot be used in a place without a power source, and the main body 3 is heavy at about 4 kg.
Since the overall length is approximately 400 mm, the main body 3 cannot be moved smoothly in a narrow space with furniture, etc., and operability cannot necessarily be said to be good. In order to improve this problem, rechargeable vacuum cleaners like the one shown in Figure 6 have come into use, but due to the relationship between the size of the storage battery and the charging capacity, current rechargeable vacuum cleaners only charge approximately 250 liters per charge. It can only be used for around a minute,
Also, due to the capacity of the dust collection case 9, it could not be said to be sufficient when used in a large area.

For this reason, it became necessary to use each vacuum cleaner separately, and in order to take advantage of the advantages of each, it was necessary to prepare two vacuum cleaners.

The present invention solves these problems,
It is an object of the present invention to provide a vacuum cleaner that can be used properly by recombining it depending on the purpose.

Means for Solving the Problem The present invention to solve this problem includes a main body case incorporating an electric blower and a large dust collection case that filters and collects dust, and a hose on the suction side of the main case. There is a small dust collection case that is detachably installed through the hose and has a dust suction port in the front, and a dust collection case that is separated from the hose and has a filter on the front and a built-in DC electric blower and a storage battery that powers it. It is equipped with a rechargeable main body that is detachably connected to the rear, and the small dust collection case is provided with a valve for attaching and detaching a hose so that it can be opened and closed.

Function: With this configuration, when cleaning your body and surroundings, you can easily use it as a rechargeable vacuum cleaner by removing the hose from the small dust collection case and connecting the rechargeable main unit. on the other hand,
When cleaning a large area or cleaning that requires strong dust suction power, remove the rechargeable main body from the small dust collection case, attach the grasping case, and connect the hose to the small dust collection case. When connected to the side, it can be used as a general vacuum cleaner, and at that time, the dust accumulated in the small dust collection case is sucked into the large dust collection case on the main case side, so you only need to dispose of garbage on the large dust collection case side. ,
Easier to throw away trash.

Embodiment The drawings (first
This will be explained based on FIGS.

In the figure, 21 includes an AC electric blower 22, a cord winding device 23, and a large dust collection case 24.
This is a main body case of a vacuum cleaner integrally equipped with a shelf suction port 25 and a gap suction port 26 covered with an upper lid 27 and housed above an AC electric blower 22 and a winding device 23. 28 is a front cover attached to the main body case 21, and a hose connection cover 29 is attached thereto. 30 is a small dust collection case, with a lid 31 on the front.
is detachably attached using a buckle 32. A connection port 33 is formed approximately in the center of the lid 31 of the small dust collection case 30, and an extension pipe 34 is inserted and connected thereto. 35 is a floor suction port connected to the tip of the extension pipe 34. Further, a valve 36 for attaching and detaching a hose is provided below the small dust collection case 30 so as to be openable and closable. 37 is a rechargeable main body which is detachably attached to the rear part of the small dust collection case 30 with a buckle 41, and contains a storage battery 38 for charging, a DC electric blower 39, etc. Further, a filter (not shown) is detachably attached to the rechargeable main body 37. 40 is a hose connecting between the large dust collection case 24 and the small dust collection case 30;
Reference numeral 42 denotes a floor suction port that is connected to the tip of the extension pipe 34 when the hose 40 is removed from the small dust collection case 30 and the small dust collection case 30 is used alone. When used with the dust case 30 connected to the hose 40, it may be smaller than the floor suction port 42 connected to the tip of the extension pipe 34. Reference numeral 43 denotes a handle case that is detachably attached to the rear part of the small dust collecting case 30 using the buckle 41 in place of the rechargeable main body 37 when used as a general vacuum cleaner.

Next, the operation of this configuration will be explained.

For cleaning around the house, the hose attachment/detachment valve 36 formed in the small dust collection case 30 is closed, and the vacuum cleaner is used as a rechargeable vacuum cleaner configured as shown in FIG. 4. In this case, it can be kept assembled even when not in use, so it can be used immediately when needed.

Next, when cleaning a large area, open the hose attachment/detachment valve 36 formed on the small dust collection case 30, insert the hose 40, and connect it to the main body Ace 21.
A handle case 43 is attached to the small dust collection case 30 instead of the rechargeable main body 37 and used in the state shown in FIG. 3.

This allows it to be used as both an easy-to-use rechargeable vacuum cleaner and a single-stage electric vacuum cleaner, bringing out the strengths of each. Also, when you don't have enough time for cleaning, you can use it as a rechargeable type, and when you have time, such as on weekends, you can use it as a regular vacuum cleaner. In addition, small dust collection case 30
and the large dust collection case 24 are connected by a hose 40, and when the small dust collection case 30 is used as a general vacuum cleaner, the dust accumulated in the small dust collection case 30 is transferred to the large dust collection case 24, Only the large dust collection case 24 is sufficient for disposing of garbage.

Effects of the Invention As described above, according to the present invention, by making the small dust collection case of the rechargeable vacuum cleaner and the vacuum cleaner detachable via the hose, it is possible to take advantage of the advantages of each and use them properly. In addition, when used as a general vacuum cleaner, the dust accumulated in the small dust collection case is transferred to the large dust collection case of the vacuum cleaner through the hose, so the dust accumulated in the large dust collection case should be disposed of. It is possible to provide a vacuum cleaner that requires only dust, has improved usability, and has high usability as a rechargeable or general vacuum cleaner.
