[Problems to be Solved by the Invention] However, in the conventional vacuum cleaner, the filter 54 provided in the first exhaust chamber 55
Therefore, a deodorizing filter 57 containing a deodorizing agent such as activated carbon or an aromatic agent is provided in the second exhaust chamber 56 located further downstream, and the filter 54 in the first exhaust chamber 55 is , there is no deodorizing means, and therefore, the odor that adheres to the upstream side of the filter 54 along with fine dust accumulates and becomes strong, and is further heated by exhaust heat, causing the odor to be removed from the filter 54 itself. The strong odor air that has passed through the filter 54 significantly reduces the deodorizing ability of the deodorizing filter 57 located downstream of the filter 54, and as a result, the deodorizing filter 57 57, there was a problem in that air with a strong odor was exhausted from the exhaust port 52.

[0004] Also, the filter 54 is attached to the main body case 50.
Since airtightness is required for the exhaust chamber 55, the exhaust chamber 55 must be specially configured, which complicates the structure, leading to an increase in the number of parts and assembly man-hours, and making it difficult to attach and detach the filter. There was also the problem of The present invention was invented in view of the above problems, and its purpose is to fundamentally eliminate the exhaust odor emitted from a vacuum cleaner by removing the odor that accumulates in the filter itself. can be easily attached and detached, and the structure of the main body case can be simplified. The company provides vacuum cleaners.

[0005]

[Means for Solving the Problems] In order to achieve the object, the present invention incorporates an electric blower in a main body case equipped with a dust collection chamber and an exhaust port, and the air sucked into the dust collection chamber by the electric blower. In a vacuum cleaner configured to discharge air from an exhaust port, a high-performance filter for filtering air discharged from the electric blower is provided downstream of the electric blower and upstream of the exhaust port. In addition, a deodorizer is provided on the suction surface on the upstream side of the filter, and an opening is provided on the bottom surface of the main case, and a frame that airtightly supports the filter is attached to and detached from the opening. It is characterized in that it can be freely attached and the opening can be closed by the frame.

[0006]

[Function] With the above configuration, since the deodorizer is provided upstream of the high-performance filter, the odor attached to the filter along with fine dust is chemically decomposed by the deodorizer while the operation is stopped. Since the odor source of the filter itself can be fundamentally removed and the filter can always be kept in a clean state, the exhaust air filtered through this purified filter is always odor-free and clean air. Therefore, it can be discharged.

Furthermore, by opening the bottom surface of the main case and closing this opening with a frame that supports the filter, the structure of the main case can be simplified and the filter can be attached and removed very easily. It is possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A vacuum cleaner according to the present invention will be explained based on the embodiments shown in the drawings. FIG. 1 shows an example of a vacuum cleaner equipped with the present invention. This vacuum cleaner has main case 1
A suction port 2 to which a hose (not shown) is connected is provided at the front upper part of the main body case 1, a dust collection chamber 3 communicating with the suction port 2 is provided inwardly, and an exhaust port 4 is provided at the rear end of the main body case 1. An electric blower 6 is provided behind the dust collection chamber 3, that is, on the downstream side, with a filter medium 5 interposed therebetween.

On the other hand, a compartment 7 is formed between the upstream side of the exhaust port 4 and the downstream side of the electric blower 6, and the compartment 7 is mainly equipped with a high-density filter having a bellows-shaped filter material. A high-performance filter 8 having a surface is airtightly supported on the inner surface of a compartment 7 formed in the main body case 1 via a frame 9. Further, as shown in FIG. 2, the filter 8 has a suction surface 10 on the upstream side of the filter 8 made of a material capable of chemically decomposing odor components, such as Aniko (manufactured by Minato Sangyo) or Shiraimatsu (Shirai Pine). Deodorant 11
is loaded, and the deodorant 11 is held down by a net 12 so as to be stably supported on the suction surface 10.

Further, in the present invention, as shown in FIG. 3, an opening 13 is provided on the lower surface of the main case 1, and the opening 13 is closed with a frame 9 that supports the filter 8. . In detail, the compartment 7 formed in the main body case 1
An opening 13 is formed in the lower surface of the filter 8 through which the frame 9 that airtightly supports the filter 8 can easily pass through, and the frame 9 that airtightly supports the filter 8 is inserted into the opening 13. The bottom 14 of the frame 9 is connected to the opening 1
3 by means of attachment means 15 to close the opening 13.

Next, the operation of the embodiment constructed as described above will be explained. In the above embodiment, the dust sucked in from the suction port 2 through the hose when the electric blower 6 is operated is collected in the dust collection chamber 3, and the afterflow from the dust collection chamber 3 is passed through the filter medium 5.
The air is guided to a compartment through the compartment 7, filtered and purified by a filter 8 in the compartment 7, and then discharged from the exhaust port 4 to the outside of the machine.

[0012] In this embodiment, the suction surface 10 on the upstream side of the filter 8 is coated with Anico (manufactured by Minato Sangyo) or Shiraimatsu (manufactured by Shirai Matsumono Pharmaceutical), which can chemically decompose odor components. By loading the deodorant 11, it is possible to prevent fine dust adhering to the suction surface 10 of the filter 8 from being heated by exhaust heat and becoming a source of bad odor. That is, while the electric blower 6 is not operating, the filter 8 with a foul odor is chemically decomposed by the chemical action of the deodorizing agent 11, and the foul odor attached to the filter 8 itself can be fundamentally removed. The air filtered and discharged through the filter 8 from which the foul odor has been removed is always clean air free of foul odors and is discharged from the exhaust port 4 to the outside of the machine.

[0013] Also, an opening 1 provided on the bottom surface of the main body case 1
3 is closed with a frame 9 that airtightly supports the filter 8, so the filter 54 is placed on the main body 50 side as in the conventional case.
There is no need for a special structure to airtightly mount the filter 8, and as a result, the structure of the main body case 1 can be simplified, and the filter 8 can be attached and detached extremely easily.

[0014]

Effects of the Invention As explained above, in the present invention, since a deodorizing agent is provided upstream of a high-performance filter, the chemical action of the deodorizing agent can fundamentally eliminate odors attached to the filter itself. It has the effect of reliably deodorizing the odor contained in the air discharged from the vacuum cleaner.

Furthermore, by closing the opening provided in the main body case with a frame that airtightly supports the filter, the structure of the main body case can be simplified and the manufacturing process can be reduced, and the attachment and detachment of the filter can be simplified. Since it is extremely easy to perform, it has the effect of further improving the maintenance of the filter.
