Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner for general household use.

2. Description of the Related Art 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 device 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 blow the dust sucked in from the floor suction device 6 into the main body 3.
It is transported and stored inside.

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 1o, and a floor suction tool 11. When using it, you can easily use it without connecting a cord like a regular vacuum cleaner.

Problems to be Solved by the Invention However, the general vacuum cleaner 1 is easy to use because it is light to hold in the hand, but the main body 3 weighs about 4K.
It is heavy (about 40 g) and has a long overall length of about 40 mm, so it is difficult to move the main body 3 smoothly in a narrow space with furniture, etc., and the operability cannot necessarily be said to be good. To improve this, rechargeable vacuum cleaners 2 have been used, but current rechargeable vacuum cleaners 2 only last for about 25 minutes due to the size of the storage battery and charging capacity.
It could not be used after one charge, so it could not be said to be 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 strengths of each, K had 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 The technical means of the present invention for solving the above-mentioned problems is a main body case with a built-in electric blower, etc., and a dust collector for accumulating and depositing the sucked dust. The case is separated and connected with a flexible hose, and a rechargeable drive body containing a rechargeable storage battery and a DC electric blower can be detachably connected to the dust collection case.

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 body case, which makes the main body case very small, making it easier to move around in narrow spaces, and improving usability. be.

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

1 to 4, reference numeral 21 denotes a main body case of a vacuum cleaner that incorporates an electric blower 22 and a cord winding device 23 (indicated by a one-dot chain line); At the top there is a suction tool 24 for shelves and a suction tool 25 for opening the gap.
is stored covered with an upper lid 26.

27 is a front lid attached to the main body case 21, and a port connector 28 is attached thereto. Reference numeral 29 denotes a dust collection case, and a dust collection case lid 3o is detachably attached to the dust collection case 29 at the front by means of a front buckle 31. 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 denotes an intake port body held in the handle case 35, and 39 an indicator device for estimating the dust accumulation state Bf based on pressure changes inside the dust collection case 29. Reference numeral 40 denotes a hose insertion port provided on the handle case 35, into which a combustible hose 41 connected to the hose connection lid 28 on the main case 21 side is inserted and connected to the main case 21 side in this state.

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

Reference numeral 43 denotes a rechargeable drive body which is attached after removing the handle case 35 from the dust collection case 29, and includes a storage battery 44 for charging, a DC electric blower 45, etc. 46 is another floor suction device.

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. , it can always be left assembled even when not in use.
It can be used immediately when used.

Next, when cleaning a large area, remove the rechargeable drive main body 43 from the dust collection case 29, attach the handle case 35, insert the hose 41 into the hose insertion port 40 and connect it to the main case 21. Use under the conditions shown. At this time, the main body case 21 has a separate dust collection part compared to a conventional vacuum cleaner, so the weight and size are reduced by about 60 to 70%, so it can be used like furniture etc. placed side by side. It can be moved around very easily even in tight spaces.

Furthermore, 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.When you don't have enough time for cleaning, you can use it as a rechargeable type and use it on weekends, etc. If available, it can be used as a general vacuum cleaner.

Further, unlike the conventional hose 41, dust does not pass through the inside of the hose 41, so there is no chance of dust clogging on the way.

Moreover, the hose 41 can be made thinner and lighter, and the load applied to the rear part of the hose 41 from the handle case 35 can be reduced to further improve operability.

Effects of the Invention As can be seen from the above description, the present invention reduces the weight of the rear part of the handle case by separating the dust collection case for accumulating dust from the main body that houses an electric blower, etc. However, the main body case can be made smaller to allow for tighter turning, improving usability and operability.

Furthermore, by attaching the rechargeable drive body to the dust collection case, you can easily use it as a rechargeable vacuum cleaner without the need for assembly or cord extraction, and when you don't have enough time for cleaning or It is possible to provide a vacuum cleaner that is effective for cleaning in narrow spaces and has high usability as a rechargeable or small-turning general vacuum cleaner.
