Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vacuum cleaner, and particularly to a vacuum cleaner having a deodorizer storage structure effective in alleviating bad odors in a dust collection chamber.

[Conventional technology]

Conventional methods to eliminate bad odors in the dust collection chamber include methods of putting deodorizer into the dust collection chamber, deodorizing and antibacterial treatment of paper bag filters, and methods of placing deodorizer near the dust collection chamber and using chemical agents. There are methods such as suctioning (qi). [Problems to be Solved by the Invention] Among the conventional techniques, the present invention relates to a method of directly injecting the deodorizing agent into the dust collection chamber. There is no technology that combines both aspects for the effective use of vacuum cleaners, and it is difficult to replace them. Even if they are attached, the chemicals do not plow out effectively, or the vacuum cleaner's movement (standing upright or falling over while cleaning) causes the product to be installed. There were problems such as the chemicals moving from their normal installation locations and the deodorizing/fragrance agents causing chemical changes in plastic parts. The purpose of the present invention is to easily attach a deodorant air freshener,
An object of the present invention is to provide a vacuum cleaner having a configuration that allows effective use of chemicals during retention, removal, and attachment. [Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for easily attaching and detaching a deodorizing fragrance to a filter stand for attaching a paper bag filter,
Moreover, it is characterized by providing a storage part that can be held securely.

[Effect]

The deodorizing/air freshener storage section provided in the filter stand above is
It consists of locking protrusions that hold the drug in the four parts that house the drug, and a window provided at the bottom of the recess, and the drug is impregnated in cotton wick or the like and then wrapped in aluminum foil or the like in the recess. Cut a part of the aluminum foil outer envelope and set it.
It works by installing the medicine so that it effectively flows out from the affected area at the bottom due to the suction flow of the vacuum cleaner and hits the dust in the dust collection chamber.

〔Example〕

An embodiment of the vacuum cleaner of the present invention will be described below with reference to the drawings. The vacuum cleaner body 1 includes an electric blower 2 and a Wl source cord 3.
The dust collecting section 6 includes a cord reel 4 wrapped with a cord reel 4 and a paper bag filter 5 inside, and the dust collecting section 6 is equipped with a dust collecting lid 7. The vacuum cleaner main body 1 consists of a hemispherical upper case 1a and a lower case 1b. The vacuum cleaner body 1 has casters 8 extending from the vacuum cleaner body 1 and mounted on all sides, and a wheel base 1 that can rotate with respect to the vacuum cleaner body 1 via a rotation shaft 9.
0.

To further explain each part, the electric blower 2 includes a vibration-proof rubber 1
1.12, it is held in the vacuum cleaner body 1 so as to be gripped from both sides. A sound absorbing cover 13 is placed around the electric blower 2.
, a sound insulating wall 14 is provided.

A sound deadening cylinder 15 is integrally formed with the sound insulating wall 14.

The dust collection section 6 includes an inner case 16 that contacts the vibration-proof rubber 12 on the front side of the electric blower 2. Inside the inner case 16, an after filter 17, which is made of a filter material and is formed into a box shape, is attached. The paper bag filter 5 can be attached to the inside of the after filter 17, and can be attached by attaching one side of the opening part 5a of the paper bag filter 5 to the after filter 17 and the other side to the filter stand 35. I can do it. The filter stand 35 is also provided with a recess 37 that can accommodate a deodorizing/fragrance 36, and these four parts have claws 38 to prevent the deodorizing/fragrance 36 from coming off, and a window for the deodorizing/fragrance to scatter. A section 39 is also provided. An airtight packing 18 is provided around the opening of the afterfilter 17. The airtight packing 18 is attached to the inner case 16
The opening end of the dust collector M7 comes into contact with the back cover 18 of the dust collector M7.
It is constructed to maintain airtightness. The dust collection lid 7 also has a hose attachment port 2 to which a hose 19 can be detachably attached.
0 and is configured to be rotatable. To attach and detach the paper bag filter 5, release the clamp 21 and remove the dust collector M7.
It is done by opening and closing.

The top surface of the vacuum cleaner body 1 is provided with a carrying handle 22 and a dust meter 23 that displays the amount of clogging of the filter. A plurality of wheels 24 are attached to the bottom surface of the cleaner body 1, and come into contact with the inner surface of the wheel base 10 to make the rotation of the cleaner body 1 and the wheel base 10 smooth.

Furthermore, tire portions 24a are also provided on the outer periphery of the wheels 24 to reduce running noise.

The wheel stand 10 is connected to the lower case 1b of the vacuum cleaner main body 1 and the rotating shaft 9.
It is fixed from the bottom with a screw through a washer.
It can be rotated around the rotation axis 9, but when it rotates 360 degrees, it hits the stopper 25 and the rotation is inhibited. In other words, it can be rotated 360 degrees to the right and 360 degrees to the left. Further, the wheel platform 10 is configured to have a substantially circular shape when viewed from above. The casters 8 are provided so as to protrude from the outer shape of the cleaner body 1.

A caster force bar 26 is provided on the wheel stand 10 so as to cover the caster 8. A bumper 27 is provided on the outer periphery of the caster force bar 26 and the wheel base 10 to prevent damage to furniture or the like. This bumper 27 constitutes the outermost shape of the cleaner body 1.

An exhaust port 28 and a power cord outlet 29 are provided on the rear side of the cleaner body 1.

In the above configuration, when using the vacuum cleaner, the hose 19, the extension pipe 30.
Connect the suction port 31, pull out the power cord 3 from the cord outlet 29, and insert it into the outlet 1 (not shown). Next, when the operation switch 32 at the tip of the hose 19 is turned on, the electric blower 2 is operated, and the suction force causes air flow containing a large amount of dust to flow from the suction port 31 to the extension pipe 30 and the hose 19.
The dust and clean air are separated and passed through the paper bag filter 5 into the dust removal section 6, and only the clean air flow passes through the electric blower 2 and the muffling tube 15, and is discharged from the exhaust port 28 at the rear. ．． When the room is cleaned in this state, even if the wheel stand 10 or the caster force bar 26 hits an obstacle 33 such as furniture placed in the room, the bumper 27 protects the furniture and prevents damage to the furniture.

In addition, since the main body 1 of this vacuum cleaner can rotate on the wheel stand 10, it is easy to change the direction of the hose 19 in a small room, etc., and the direction can be changed using the casters 8 on the surface to be cleaned. Instead, it rotates by means of the carriage 24 between the axle base 10 and the cleaner main body 1, so that it can be easily operated on the surface to be cleaned without being affected by the rotation. Conversely, even if the caster force bar 26 or the like gets caught on the legs of a table or the like as shown in FIG. This allows you to move the vacuum cleaner smoothly even in rooms with a lot of furniture.

Further, since the cleaner main body 1 cannot rotate freely relative to the wheel stand 10 and the rotation angle is limited, the vacuum cleaner can be routed without the power cord 3 wrapping around the wheel stand 10. Furthermore, in the vacuum cleaner of this embodiment, the casters 8 are arranged to protrude outward from the vacuum cleaner body 1, and the bumper 27 of the vacuum cleaner body 1 is configured to have the largest external dimension, so that it does not come into contact with obstacles. Even if the cleaner body 1 side to which the hose 19 is attached is fixed, the lower wheel stand 1o can be rotated to avoid the problem. Furthermore, the roots of some of the protruding casters have a smooth shape and are connected to the outer periphery of the wheel platform 10, so that even if they hit an obstacle, they can slide and avoid it, and the caster 8 can be placed more easily. Since it has four directions, it is configured to allow for smooth changes of direction and crossing over thresholds. Further, according to this embodiment, since the electric blower 2 and the cord reel 4 are arranged at a low position, a structure with a low center of gravity can be adopted to prevent the vacuum cleaner from falling over, which is advantageous. Furthermore, since the electric blower 2 part is covered by the wheel stand 10 part from the outside, the noise generated by the electric blower 2 becomes a double case structure with the lower case 1b and the case of the axle stand 10, so that the sound insulation effect is improved. By increasing the amount of noise, it is possible to achieve even lower noise. Since the shape of the cleaner main body 1 and the wheel base 10 when viewed from above is approximately a perfect circle, rotation can be performed with the minimum radius even when changing direction in a narrow area. In addition, in this embodiment, the vacuum cleaner main body 1
Although the exhaust port 28 is provided at the rear of the vacuum cleaner, it may also be a distributed exhaust port that discharges the air from the entire circumference of the sliding portion 34 of the cleaner body 1 and the wheel base 10. At this time, by configuring the opening width of the sliding part 34 to be smaller than the diameter of the power cord, it is possible to prevent the cord from getting caught in the sliding part 34 when the cleaner main body rotates.

Furthermore, as another example, if the flat part IC is configured on the top surface of the vacuum cleaner main body 1 and used as a chair, since the rotating wheels 24 are provided, the floor surface is on tatami or carpet. However, it can also be used as a rotating chair since there is no need to generate unreasonable force with these surfaces when rotating.

(Effects of the Invention) According to this embodiment, the following effects can be initialized. ■ Since the electric blower 2 and cord reel 4 are arranged at a low position, the vacuum cleaner is prevented from falling over. However, it has a low center of gravity structure, which is advantageous against overturning.

■ The 2 parts of the electric blower are covered by the 10 parts of the axle base from the outside. Since the noise generated by the W1 dynamic blower 2 has a double case structure with the lower case 1b and the case of the wheel platform 10, the sound insulation effect is increased and the noise can be further reduced.

■ Since low-speed exhaust is possible from around the entire circumference of the vacuum cleaner body, the exhaust flow discharged from the vacuum cleaner body does not kick up dust on the surface to be vacuumed.

■ Since the shape of the vacuum cleaner main body 1 and the wheel base 10 when viewed from above is almost a perfect circle, it is possible to rotate with the minimum radius even when changing direction in a narrow area. ■ A vacuum cleaner body with a built-in dust collector and electric blower that houses a filter, a wheel stand on which the vacuum cleaner body is rotatably placed, and a wheel stand that rotates and moves over the surface to be cleaned. In the vacuum cleaner, the moving means is provided at the bottom of the wheel base and protrudes outward from the vacuum cleaner body, so that it is possible to check the condition of the surface to be cleaned and the furniture, etc. The vacuum cleaner itself can run stably without getting involved with obstacles.

■ The rotation range of the vacuum cleaner body 1 on the wheel stand 10 is 360 degrees.
Even if the Wi source cord becomes entangled with the main unit due to rotation, there is a stopper that prevents it from rotating further if the main unit is rotated with excessive force, so there is no force on the power cord. It is also good for safety because no force is applied.

According to the present invention, it is possible to obtain a vacuum cleaner having a configuration that allows easy attachment and retention of a deodorant aromatic agent, and effective use of the agent during attachment.
