Description

  The present invention relates to a vacuum cleaner that removes the odor of dust sucked using a deodorizing material and reduces the odor of exhaust.

Conventionally, with regard to exhaust deodorization of a vacuum cleaner, a configuration in which a deodorizing filter is mounted in an exhaust path has been proposed, and in recent years, an idea of deodorizing by an oxidation action of a photocatalyst has also been seen (see, for example, Patent Document 1). ).
Japanese Patent No. 3238055

  However, in the method of installing a deodorizing filter in the exhaust path described above, since the suction amount of the vacuum cleaner is large relative to the size of the filter, the contact time between the deodorizing filter and exhaust air containing odor is shortened, and the deodorizing efficiency is reduced. However, there is a problem that the reduction in odor is small.

  This invention solves the said conventional subject, and it aims at providing the vacuum cleaner which reduces the odor of exhaust_gas | exhaustion significantly.

  In order to solve the above-described conventional problems, the present invention provides a deodorant storage part in a nozzle part, the deodorant storage part stores the deodorant, and the deodorant stored in the deodorant storage part is a rotating brush. This is a vacuum cleaner that is made into a powder by friction with the dust and charged into the dust collecting part.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment.

(Embodiment 1)
FIG. 1 is a configuration diagram schematically showing the configuration of the electric vacuum cleaner according to the first embodiment.

  In FIG. 1, a dust collection box 3 and an electric blower 4 as a dust collection unit are arranged inside a housing 1 constituting the main body, and a suction hose 6 and an extension pipe 7 associated with an operation unit 8 are arranged upstream. The nozzle part 2 is attached via. Further, the cleaner body is moved by the wheels 5.

  Here, a centrifugal cyclone cleaner that separates dust by a swirling flow is used, and its configuration will be briefly described with reference to FIG.

  2A and 2B are diagrams schematically showing the dust collection box 3 of the electric vacuum cleaner shown in FIG. 1, wherein FIG. 2A is a side view and FIG. 2B is a front view.

  In FIGS. 2A and 2B, the air is sucked by the electric blower 4 from the downstream side of the first filter 22. The air containing the sucked dust is first sucked from the vent 21 of the dust collection box 3, and the air containing the dust flows along the barrier 23, where the air passes through the first filter 22 and the electric blower 4. However, the dust is further swirled by the centrifugal force, and finally the second filter 24 filters the dust, and most of the dust stays in the dust storage unit 25. The solid line arrows shown in the figure indicate the flow of dust, and the broken line arrows indicate the flow of airflow. As described above, a centrifugal cyclone cleaner that separates dust by a swirling flow is used here.

  FIG. 3 is a cross-sectional view of the main part of the nozzle portion 2. A rotating brush 31 having a brush 32 is disposed inside the nozzle portion 2, and a deodorant storage portion 33 having an open bottom surface is disposed above the nozzle, and a substantially cuboid deodorant 34 is stored therein. Has been. Further, the deodorant 34 is pressed by a spring 35 from the inner top surface of the deodorant storage portion 33. Here, the deodorizing agent 34 is a powdery zeolite having an average particle size of 5 micrometers, which is hardened in a substantially rectangular parallelepiped shape using clay as a binder, and becomes an original powder form with a relatively small stress.

  FIG. 4 is a cross-sectional view of the main part of the nozzle unit 2 during operation. During operation, the rotating brush 31 rotates to rub the lower surface of the deodorant 34 pressed by the brush 32, and the deodorant 34 is scraped off by the brush 32 in the friction part to become a powdery deodorant 41, It passes through the suction hose 6 and is finally sucked into the dust collection box 3. That is, the deodorizing agent 34 is powdered by friction with the brush 32 of the rotating brush 31 and is sucked into the dust collection box 3 so that it can be naturally introduced during cleaning without using any external force. is there.

  Further, here, the deodorant 34 is pressed by the spring 35, so that the powdery deodorant 41 is introduced in an amount substantially proportional to the cleaning time, that is, the amount of dust, and is effectively deodorized without waste. It will be. Furthermore, as shown in FIG. 5, even if the deodorizing agent 34 becomes smaller due to wear, the deodorizing agent 34 can be used without waste because it is pressed by the spring 35 and charged to the end.

  In the first embodiment, the deodorizing agent 34 is powdered by the rotating brush 31, but the nozzle unit 2 is provided with a rotating member (not shown) that cuts the deodorizing agent 34 into powder by cutting it exclusively. However, the same effect can be obtained.

  The effect of the present invention was verified by experiments using the vacuum cleaner having the above configuration.

(Experimental example 1)
The room was cleaned for 15 minutes using the above vacuum cleaner. As a control experiment, the room was cleaned for 15 minutes without deodorant. This cleaning experiment was continued for 10 days while paying attention to the exhaust odor. As a result, the odor of exhaust gas was felt strongly from the fifth day in the control experiment, but almost no odor was felt in the first embodiment until the end of the tenth day.

  When the amount of dust sucked into the vacuum cleaner was compared, approximately 10 grams of both the present embodiment and the control experiment were sucked after 10 days of cleaning. Moreover, the deodorizer 34 installed in the vacuum cleaner of this embodiment was reduced by about 0.3 g. Therefore, an average of 3 g of dust per day is sucked and 0.03 g of powdery deodorant is introduced.

  At this time, when the dust collected by suction was observed, it was confirmed that the deodorizer 34 adhered to the dust as the powder deodorizer 41 and the dust was covered with the powder deodorizer 41.

Next, after standing for 1 day in this state where 30 g of dust was sucked, a vacuum cleaner was set in a 1 m ³ sealed chamber and operated for 30 seconds. The odor exhausted into the chamber was actually smelled by 6 panelists and sensory evaluated. As a result, the average odor intensity of the present embodiment was 1.4, whereas the control experiment was 3.2, confirming a significant odor reduction effect.

  From the above, by introducing a powder deodorant into the sucked dust as in the present embodiment, the deodorizer covers the dust and removes the odor of the dust strongly. Since deodorization is performed even during installation, odor retention in the dust collecting portion is reduced, and exhaust odor can be reduced even at the initial stage of use of a cleaner having a high odor level.

(Experimental example 2)
An experiment similar to Experimental Example 1 was performed with a paper pack type vacuum cleaner. A chamber test of 1 m ^{3 was} conducted for 10 days in the same manner as in Experimental Example 1. As a result of sensory evaluation, in the control experiment in which the deodorizer 34 was installed, the deodorizer was not installed with respect to the odor intensity 1.8, which was 3.2.

  From the results of Experimental Example 1, it was confirmed that the centrifugal cyclone cleaner according to the present embodiment is more effective than the paper pack cleaner. This is because in the centrifugal separation type, dust is swirled in the dust collection box 3 when sucked, the mixing of the powdered deodorant 41 and the dust is improved, and the adhesion and covering effect of the powdered deodorant 41 is increased. is there.

  In this embodiment, zeolite is used as a deodorizing agent. However, in addition to zeolite, silica, alumina, activated carbon, and the like can reduce composite odor such as vacuum cleaner dust and have the same effect.

  Moreover, in this Embodiment, although the deodorizer storage part 33 was arrange | positioned on the outer side of the rotating brush 31, as shown in FIG. 6, the brush 32 of the rotating brush 31 is also provided in the inner hollow part, and rotating brush 31 itself is provided. If the deodorant storage portion 33 is formed in a shape that allows ventilation, and the nozzle portion 2 is fixed to the support 61 provided at the side end portion of the rotary brush 31 so as not to rotate together with the rotary brush 31 in the hollow portion of the rotary brush 31. The deodorizer 34 can be made into a powder by friction with the brush 32 while being configured compactly. In this case, the inside of the rotating brush 31 is not limited to the brush, but may be a cutting blade or a file.

(Embodiment 2)
Next, a second embodiment of the present invention will be described.

As shown in FIG. 7, an experiment was performed by placing a deodorizing filter 71 in the exhaust part of the cleaner used in the first embodiment. As the deodorizing filter 71, an 80 cell / inch ² honeycomb body 120 cc carrying 12 g of activated carbon was used.

As in the first embodiment, a cleaning experiment was conducted for 10 days, and then a 1 m ³ chamber test was conducted. As a result of sensory evaluation, the one with a deodorizing filter installed was odor intensity 1.1, while the result of Experimental Example 1 of Embodiment 1 was 1.4 with only a deodorizing agent installed, no control In the experiment, it was 3.2.

  Thus, by introducing the powdery deodorant 41 and disposing the deodorizing filter 71 in the exhaust path, the exhaust odor can be reduced at a very high level, and a more useful vacuum cleaner can be obtained.

(Embodiment 3)
Next, a third embodiment of the present invention will be described.

  In the present embodiment, 10 parts by weight of the deodorizer 34 is added to 1 part by weight of zeolite containing 5% silver as an antibacterial material, and solidified using clay as a binder.

  A cleaning experiment was conducted for 10 days in the same manner as in the first embodiment. At this time, 1 g of the dust mixed with the powdery deodorant 41 was dispersed in water containing a surfactant and cultured on an agar medium at 35 ° C. for 40 hours to examine the growth of the bacteria. As a control experiment, the one of the first embodiment was used.

  As a result, 99% or more of the antibacterial effect was confirmed in the present embodiment as compared with the first embodiment.

  From the above, the antibacterial material is included in the deodorizer, so that the antibacterial material directly acts on the dust to prevent the growth of bacteria in the dust collection part, and the hygienic and odor derived from the bacteria is reduced. It can also be effective in terms of odor. Here, although silver is used as the antibacterial material, the same effect is exhibited as long as it has an antibacterial effect such as zinc other than silver.

  As described above, the vacuum cleaner according to the present invention is a vacuum cleaner in which the powdered deodorant is put into the dust collecting part from the deodorant storage part provided in the nozzle part. In addition, since it can be a vacuum cleaner that reduces the odor of exhaust, it can be applied to business use as well as household vacuum cleaners.
