  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)
Hereinafter, a first embodiment of the present invention will be described.

  FIG. 1 is a configuration diagram of the main body of the vacuum cleaner according to the first embodiment, FIG. 2A is a side view of a schematic configuration diagram of a dust collection box of the vacuum cleaner, and FIG. FIG. 3 is a front view of a schematic configuration diagram of a dust collection box of the vacuum cleaner, and FIG. 3 is a configuration diagram of a deodorizing material storage unit provided upstream of the dust collection box of the vacuum cleaner.

  In FIG. 1, a dust collection box (dust collection chamber) 3 and an electric blower 4 are arranged inside a main body 1 constituting the main body, and dust is collected in the dust collection box 3 on the upstream side. The suction port 2 is open, and a connection hose is attached here. Moreover, the cleaner body is configured to be movable by the wheels 15.

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

  In FIG. 2A and FIG. 2B, the air that is sucked from the downstream side of the first filter 22 by the electric blower 4 is first drawn from the vent 21 of the dust collection box 3. The air that is sucked and contains dust flows along the barrier 23, where the air is sucked into the electric blower 4 through the first filter 22, but the dust is further swirled by centrifugal force and finally the second second Dust is filtered out by the filter 24, and most of the dust stays in the dust collecting 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.

  In FIG. 3, the deodorizing material storage part 26 is provided in the connection pipe 5 located in the upstream part of the dust collection box 3, and the deodorizing material 31 is accommodated in the inside.

  Further, a deodorizing material cutting blade (deodorizing material cutting means) 35 that is pivotally supported by a rotary shaft 40 on the connection pipe intake passage side of the deodorizing material storage portion 26 and rotates in the direction of the arrow in the drawing by the suction air in the connection pipe 5 is provided. Provided and open in the bottom direction. A substantially cuboid-shaped deodorizing material 31 is housed here. The deodorizing material 31 is obtained by solidifying powdered activated carbon having an average particle diameter of 20 micrometers into a substantially rectangular parallelepiped shape using colloidal silica as a binder. Further, the deodorizing material 31 may have a polygonal shape or a substantially spherical shape. Here, when the deodorizing material cutting blade 35 receives the wind pressure of the suction air in the connection pipe 5 and starts to rotate, the deodorizing material cutting blade 35 cuts the lower surface side of the deodorizing material 31 and can be granulated by wear. Is.

  The effect of the present invention was investigated using the vacuum cleaner having the above configuration.

  The actual room was cleaned for 15 minutes using the above vacuum cleaner. As a control experiment, the actual room was cleaned for 15 minutes without a deodorizing material. This cleaning experiment was continued for 10 days while paying attention to the exhaust odor. As a result, the odor of the exhaust was noticed from the fifth day of the control experiment, but it was hardly noticed until the end of the tenth day of the present example.

  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 deodorizing material 31 installed in the vacuum cleaner of this embodiment was reduced by 1.2 g. Therefore, an average of 3 g of dust per day is sucked and 0.12 g of deodorizing material is introduced.

  At this time, when the dust collected by suction was observed, it was confirmed that the deodorizing material 31 clings to the dust as a powder and is mixed with the dust. This is because each time the cleaner body is moved and sucked, the spherical deodorizing material 31 rolls and vibrates inside the deodorizing material storage portion 26 and wears by contacting with the bottom made of a wire mesh. Is charged as powder and is in contact with and mixed with the sucked dust.

Next, after leaving still for one 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 subjected to sensory evaluation by smelling the odor with six panelists. As a result, the average odor intensity of the present embodiment was 1.8, while the control experiment was 3.0, confirming a significant odor reduction effect.

  Taking into consideration that the odor intensity 2 is the odor perception threshold, the odor intensity 1.8 is a level at which no odor can be detected even if it can be detected as an odor, and the odor can be reduced at a high level. I understand that.

  From the above, as in this embodiment, the deodorizing material is directly applied to the sucked dust, so that the odor of the dust is strongly removed and deodorized not only at the time of use but also at rest. Odor retention is reduced, and the exhaust odor can be reduced even at the initial stage of use of a cleaner having a high odor level.

  In the present embodiment, activated carbon is used as the deodorizing material. However, in addition to activated carbon, silica, alumina, zeolite, and the like can reduce the composite odor such as cleaning dust and have the same effect.

  In addition, by storing the deodorizing material in the connection pipe part, it is possible to expand the use by sharing the hose with the vacuum cleaner body of other specifications, and it can be provided to the user at a low cost. It will be.

  Of course, the deodorizing material can be formed in the dust collection box.

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

  FIG. 4 shows a configuration diagram of the deodorizing material storage unit 26 provided in the upstream portion of the dust collection box (dust collection chamber) 3.

  In FIG. 4, the inlet 8 of the deodorizing material 31 granulated from the solid is provided on the intake passage side of the connection pipe 5 of the deodorizing material storage portion 26, and a diaphragm 45 is disposed in the deodorizing material storage portion 26 above. It is provided to ensure airtightness. Furthermore, a deodorizing material cutting blade (deodorizing material cutting means) 35 urged toward the inner surface side of the upper diaphragm 45 by a coil spring 46 is provided.

  According to this, when the user starts the operation of the electric blower 4 in order to start cleaning, the vacuum pressure in the deodorizing material storage unit 26 is increased by the intake vacuum pressure generated by the electric blower 4, and the diaphragm 45 is moved downward. Shrink. In conjunction with this, while the deodorizing material cutting blade 35 is moved downward, the side surface of the deodorizing material 31 is cut and the deodorizing material 31 is granulated. The granulated deodorizing material 31 falls from the inlet (opening) 8 and is sucked together with the dust sucked into the dust collection box 3. On the other hand, when the operation of the electric blower 4 is stopped, the vacuum pressure in the deodorizing material storage unit 26 is lowered, and the side of the deodorizing material 31 is cut by the reverse action to granulate the deodorizing material 31. . The deodorizing material 31 is granulated in conjunction with the operation and stop operation of the vacuum cleaner, and the deodorizing effect can be obtained accurately.

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

  In FIG. 5, an anti-deodorizing material storage portion side of the diaphragm 45 is provided with an electric blower chamber 43 that receives an exhaust pressure during operation of the electric blower 4 and an exhaust pressure chamber 47 that is airtightly connected by an exhaust communication passage 44.

  According to this, when the user starts the operation of the electric blower 4 in order to start cleaning, the vacuum pressure in the deodorizing material storage unit 26 is increased by the intake vacuum pressure generated by the electric blower 4, and the exhaust pressure chamber 47 is filled. A positive pressure higher than the atmospheric pressure is applied, and the diaphragm 45 is rapidly contracted downward. In conjunction with this, while the deodorizing material cutting blade (deodorizing material cutting means) 35 is moved downward, the side surface of the deodorizing material 31 is cut to granulate the deodorizing material 31. The granulated deodorizing material 31 falls from the inlet 8 and is sucked together with the dust sucked into the dust collection box 3. The deodorizing material 31 can be granulated in conjunction with the operation of the electric vacuum cleaner and reliably put into the dust collection box (dust collection chamber) 3 to accurately obtain the deodorizing effect.

(Embodiment 4)
Next, a fourth embodiment of the present invention will be described.

  In FIG. 4, the outer upper side of the diaphragm 45 is pushed with a finger or the like according to the user's intention, the deodorizing material cutting blade (deodorizing material cutting means) 35 is operated, the deodorizing material 31 is granulated, and the dust collecting box (dust collecting chamber). 3 can be thrown into.

  According to this, when a user who cares about exhaust odor wants to obtain a more deodorizing effect, the amount of the granulated deodorizing material can be forcibly increased. Because the hair loss of animals emits animal odors, after exhausting with a vacuum cleaner, it exerts a strong deodorizing effect, and exhausts the deodorized exhaust during cleaning use, so that the odor environment in the house Can be maintained comfortably.

(Embodiment 5)
Next, a fifth embodiment of the present invention will be described.

  6 (a) and 6 (b), the electric blower 4 is sucked from the downstream side of the first filter 22, but the air containing the sucked dust is first stored in the dust collection box (dust collection chamber) 3. Air that is sucked from the vent 21 and contains dust flows along the barrier 23, where air is sucked into the electric blower 4 through the first filter 22, but the dust is further swirled by centrifugal force and finally In addition, dust is filtered out by the second filter 24, and most of the dust stays in the dust collecting 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. Thus, here, the configuration of a centrifugal cyclone cleaner that separates dust by a swirling flow is shown. A deodorizing material 31 is housed in the front part of the dust collection box 3, and an inlet 8 is provided in the lower part for introducing granulated deodorizing material. In the dust collection box 3, the impeller 50 that rotates by receiving the swirling flow of the sucked air is on the center side where the swirling flow flows, and is connected to the impeller 50 to rotate and rotates the deodorizing material cutting blade (deodorizing material cutting means). 35 is provided in the deodorizing material storage unit.

  According to this, while operating the electric blower of the vacuum cleaner, the deodorizing material is cut by the swirl flow in the dust collection box and continuously put into the dust collection box. By providing the impeller on the center side of the flow, the sucked dust can be prevented from clinging to the impeller. The deodorizing material 31 can be continuously granulated and put into the dust collection box 3, and the odor environment in the house can be maintained comfortably.

  As described above, the vacuum cleaner according to the present invention can remove the odor of dust by a simple means and can greatly reduce the odor of exhaust gas. it can.
