Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner used in general households.

Conventional technology Conventionally, vacuum cleaners include a general vacuum cleaner 1 that uses an AC power source as shown in Fig. 5, and a vacuum cleaner 1 that has an internal storage battery and is rechargeable from an AC power source as shown in Fig. 6. There was a rechargeable vacuum cleaner 2 that was used as a vacuum cleaner.
The vacuum cleaner 1 is connected to a main body 3, a hose 4, an extension pipe 5, and a floor suction tool 6, 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 tool 6 to the inside of the main body 3 and accumulate it.

The rechargeable vacuum cleaner 2 is composed of a charging main body 8 containing a storage battery and a DC electric blower, a dust collection case 9, an extension tube 10, and a floor suction tool 11. When using
It is easy to use without having to connect a cord like a regular vacuum cleaner.

Problems to be Solved by the Invention However, with the general vacuum cleaner 1, the part that is held in the hand is light and easy to use, but the main body 3
Because it weighs about 4 kg and has a large overall length of about 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. To improve this, rechargeable vacuum cleaners 2 have come into use, but current rechargeable vacuum cleaners 2 only last about 25 minutes per hour due to the size of the storage battery and charging capacity.
It can be used with one charge, so it was not sufficient when used in a large cleaning 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 conventional problems and provides an easy-to-use vacuum cleaner.

Means for Solving the Problems Technical means of the present invention for solving the above problems include a main body case incorporating an electric blower;
An air intake connection body is provided on the suction side of the main body case via a hose, and the air intake connection body is detachably connected to the suction side of the body case, and filters and collects dust sucked from the front air intake port. The device is equipped with a dust collection case for collecting dust, and a rechargeable drive body that is detachably connected to the rear of the dust collection case separated from the air intake connector and has a built-in DC electric blower and a storage battery that serves as its power source. .

Effect This effect is as follows. For cleaning around you, you can easily use the rechargeable drive unit as a rechargeable vacuum cleaner by connecting it to the dust collection case. On the other hand, when cleaning a large area, connect the dust collection case and main case with a hose. Therefore, unlike conventional vacuum cleaners, the dust collection case is separated from the main case, which makes the main case much smaller, making it easier to move around in narrow spaces, and improving usability. Since there is only one dust collection case, the trouble of garbage disposal is also reduced. Further, since dust does not pass through the hose between the main body case intake connectors, the hose is thinner and lighter.

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

In Figures 1 to 4, 21 is an electric blower 2.
2. A main body case of a vacuum cleaner that incorporates a cord winding device 23 (indicated by a chain line), and above the electric blower 22 and cord winding device 23 are a shelf suction tool 24 and a gap suction tool 25. is stored covered with an upper lid 26.

27 is a front lid attached to the main body case 21, and a hose connector 28 is attached thereto. 29 is a dust collection case, and the dust collection case lid 30 is attached to the front buckle 3.
1, it is detachably attached to the dust collection case 29. A connection port 32 is formed approximately in the center of the dust collection case lid 30, and an extension pipe 33 is connected to the connection port 32. 34 is a floor suction device connected to the extension pipe 33.

Reference numeral 35 denotes a handle case that is detachably attached to the dust collection case 29 with a rear buckle 36, and a handle 37 is formed from the top to the rear. Reference numeral 38 indicates an intake port body held by the grip case 35, and reference numeral 39 indicates an indicator device for estimating the state of dust accumulation based on pressure changes inside the dust collection case 29. 40
is a hose insertion port provided in the gripping case 35;
A flexible hose 41 connected to the hose connection lid 28 on the main body case 21 side is inserted and connected to the main body case 21 side in this state.

Note that a paper bag 42 is attached to the dust collecting case 29 for storing the sucked dust.

43 is a rechargeable drive body that can be attached after removing the grip case 35 from the dust collection case 29;
It has a built-in storage battery 44 for charging, a DC electric blower 45, and the like. 46 is another floor suction tool.

Next, the operation of this configuration will be explained.

For cleaning around the house, it is used as a rechargeable vacuum cleaner configured as shown in Fig. 4. At this time,
It can always be left assembled even when not in use, so it can be used immediately when needed.

Next time when cleaning a large area, use dust collection case 2.
Remove the rechargeable drive main body 43 from 9, attach the grip case 35, and insert the hose 41 into the hose outlet 4.
0, connect it to the main body case 21, and use it in the state shown in FIG. At this time, the main body case 21 has a separate dust collection part compared to conventional vacuum cleaners, so the weight and size are reduced by about 60 to 70%, so it looks like furniture etc. are placed side by side. It can be moved around very easily even in tight spaces.

In addition, it can be used as a handy rechargeable vacuum cleaner or as a regular vacuum cleaner, so you can take advantage of the advantages of each, so when you don't have enough time to clean, you can use it as a rechargeable one, giving you extra cleaning time on weekends etc. If available, it can be used as a general vacuum cleaner.

Further, unlike in the conventional case, dust does not pass through the hose 41, so there is no possibility of dust clogging in the middle. Moreover, the hose 41 can be made thinner and lighter, and the load applied to the hand at the rear portion of the gripping case 35 can be reduced to further improve operability.

Effects of the Invention As can be seen from the above description, the present invention separates the dust collection case for accumulating dust from the main body that houses an electric blower, etc., thereby reducing the weight of the rear part of the gripping case. The case can be made smaller and more maneuverable, improving usability and operability.

Furthermore, by attaching the rechargeable drive unit to the dust collection case, you can easily use it as a rechargeable vacuum cleaner without the need for assembly or pulling out the cord. It is possible to provide a vacuum cleaner that is effective for cleaning and has high usability as a rechargeable or small-turn general vacuum cleaner.
