Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner which can also be used as an air cleaner.

2. Description of the Related Art Conventionally, vacuum cleaners and air purifiers existed independently, as shown in FIGS. 5 and 6. A vacuum cleaner 1 has a main body 2 with a built-in electric blower and a hose 3. Extension tube 4. The floor suction ports 5 are connected to each other, a power cord 6 removably housed inside the main body 2 is pulled out, and the power cord 6 is inserted into a power outlet for use. In this state, the electric blower built into the main body 2 is operated to suck in dust on the floor from the floor suction port 5, transfer it to the inside of the main body 2, and accumulate it.

On the other hand, the air purifier 7 has an intake hole 9 in the curved part of the main body 8, an exhaust hole 10 and a power switch 11 at the top, and a power cord 12 at the rear. Use with.

In this state, the electric blower built into the main body 8 is operated to suck in dust from the air through the intake hole 9, collect this dust with a filter installed after the intake hole 9, and exhaust clean air through the exhaust hole 10. It is.

Problems to be Solved by the Invention As mentioned above, the vacuum cleaner 1 is used to suck in dust on the floor, etc., and the air purifier 7 is used to suck in dust in the air to clean and purify the room. However, in order to take advantage of the characteristics of each, it was necessary to prepare a vacuum cleaner and an air purifier separately.

In addition, when it comes to vacuum cleaners, the usage time is about 1 hour per day.
It cannot be said that the added value is necessarily high when looking at the time and usage time.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to make the main body of the vacuum cleaner only have a built-in electric blower, etc., and on the suction side. A filter is attached removably, and a dust collection case for accumulating and depositing inhaled dust is connected separately from the main body.

Effect This effect is as follows. When cleaning, use it as a regular vacuum cleaner. When not using it as a vacuum cleaner, remove the extension tube, dust collection case, handle case, hose, etc., and attach the filter to the main body case. The case alone can be used as an air purifier.

In this way, one unit can be used as both a vacuum cleaner and an air purifier, increasing the added value of the product.

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

In Figures 1 to 3, 13 is a main body case of a vacuum cleaner that incorporates an electric blower 14 and a cord winding device 15 (indicated by a one-dot chain line). 17 is housed covered with an upper lid 18. Reference numeral 19 denotes a front cover that is detachable from the main body case 13, and is connected to the air intake port 2Q.
is formed. Reference numeral 21 denotes a changeover switch for changing the input of the electric blower 14 provided at the upper part of the main body case 13. 22 is a dust collection case, and a dust collection case lid 23 is detachably attached to the front via a front buckle 24. A connection port 25 is formed approximately in the center of the dust collection case 22, and an extension pipe 26 is inserted and connected thereto. 2
7 is a floor suction port connected to the extension pipe 26. Reference numeral 28 denotes a handle case that is detachably attached to the dust collection case 22 with a rear lock 29, and a handle 30 is formed from the top to the rear. Reference numeral 31 designates an air intake port formed on the handle case 2, and reference numeral 32 designates an indicator device for estimating the state of dust accumulation based on pressure changes inside the dust collection case 22. 3
Reference numeral 3 denotes a hose insertion port provided on the handle case 28, into which a hose 34 connected to the intake port 20 on the main body case 13 side is inserted, and in this state is connected to the main body case 13 side.

A paper bag 35 is attached to the dust collection case 22 for collecting and depositing the sucked dust.

Further, 36 is a filter case to which a filter 37 is removably attached, and the main body case 1 is used instead of the front lid 19.
3. It can be attached and detached.

Next, the operation of this configuration will be explained.

When used as a vacuum cleaner, attach the front cover 19 to which the air intake port 20 is attached to the main body case 13, insert the hose 34 into the air intake port 2o, and open the floor air intake port 27. It is used in the state shown in FIG. 4 by being connected to the hose insertion port 33 of the handle case 28 attached to the dust collection case 22 to which the extension pipe 26 and the like are connected.

At this time, the changeover switch 21 that changes the input of the electric blower 14 is set to the "strong" position.

On the other hand, when used as an air purifier, the hose 34
etc. are not connected to the main body case 13, and instead of the above-mentioned front cover 19, a filter case 36 to which a filter 37 is detachably attached is attached to the main body case 13 and used only on the main body. At this time, the selector switch 21 is set to the "weak" position.

Effects of the Invention As can be seen from the above description, the present invention has been useful only as a vacuum cleaner in the past, but the present invention has a front cover provided with an air intake port that can be attached and detached from the main body case, and the front cover and filter can be attached and removed. By making the removable filter case replaceable, it is possible to use one unit as both a vacuum cleaner and an air purifier, increasing the added value of the product.
