(Embodiment 1)
The vacuum cleaner in the 1st Embodiment of this invention is demonstrated using FIGS.

  FIG. 1 is an overall perspective view of the electric vacuum cleaner.

  In FIG. 1, a vacuum cleaner main body 1 has a dust collecting unit (not shown) for collecting dust in the front, and an electric blower (not shown) and a cord winder (see FIG. (Not shown) is arranged. A suction port 3 communicating with the dust collecting unit is provided in the foremost part, and a connecting tube 5 of a hose 4 is detachably attached to the suction port 3. Reference numeral 6 denotes a traveling wheel rotatably attached to both side surfaces of the rear portion of the cleaner body 1, and 7 denotes a front lid that closes the dust collecting portion so as to be freely opened and closed. Reference numeral 8 denotes a handle that serves as a handle when the cleaner body 1 is transported, and is rotatably attached to an upper body 10 that holds an electric blower or a cord winder with the lower body 9.

  A tip pipe 11 is connected to the tip of the hose 4, and an extension pipe 13 is detachably connected to the tip pipe 11 by a buckle A12, and a suction tool 15 is detachably connected to the extension pipe 13 by a buckle B14. The

  The tip pipe 11 is integrally formed with a handle 16 which is a main operation handle when using the vacuum cleaner, and an operation portion of an OFF switch 17 and an ON switch 18 is arranged on the front side of the handle 16. Yes.

  FIG. 2 shows a central section of the tip pipe 11 part. The tip pipe 11 communicates with the electric blower via the hose 4 and has an intake passage A19 formed by bending in a substantially U shape and a control base 20 disposed above the intake passage A19. ing. A light receiving element 21 electrically connected to the control board 20 receives infrared rays emitted from the light emitting element 22 disposed on the lower surface facing the intake passage A19. When dust passes through the airflow that flows toward the electric blower in accordance with the operation of the electric blower through the intake passage A19, infrared rays are blocked and the amount of light received by the light receiving element 21 is reduced. This change is arithmetically processed by the control board 20 to detect dust.

  Reference numeral 23 denotes a red LED, which is turned on when the dust is detected, and notifies the user of the vacuum cleaner that the dust has been inhaled.

Reference numeral 24 denotes a light-emitting element 22, a deodorizing material storage provided between the light-receiving element 21 and the control board 20, and the upper opening covers the open / close knob 25 in an openable and airtight manner. An opening 26 is formed on the bottom surface so as to communicate with the intake passage A19. As shown in FIG. 3, which is a cross-sectional view at the ZZ position shown in FIG. 2, the opening 26 is normally closed by an operation lever 28 biased by a spring 27. A storage opening 29 is provided in the operation lever 28 so as to communicate with the opening 26, and the deodorizing material 30 made of particulate zeolite charged into the deodorizing material storage unit 24 has a predetermined amount corresponding to the size of the storage opening 29. And filled with its own weight. The operation lever 28 is slidable in the width direction of the tip pipe 11, and the operation portion 31, which is one end, is disposed so as to face the operation hole 32 provided on the side surface of the tip pipe 11. As shown in FIG. 4, when the operation unit 31 is pushed in the inside of the tip pipe 11, the storage opening 29 and the vent 33 formed in the tip pipe 11 overlap with each other, and the deodorizing material 30 filled in the storage opening 29 is replaced with the vent. After passing through 33, it falls into the intake passage A19. When the fingertip is removed from the operation unit 31, the operation lever 28 is returned to the original position by the repulsive force of the spring 27, and the deodorizing material 30 is filled again into the empty storage opening 29, and the next deodorizing material supply operation is prepared. It will be in order. Further, when the deodorizing material 30 in the deodorizing material storage unit 24 becomes a small amount due to repeated supply for deodorization, the replenishing deodorizing material 30 can be replenished by removing the opening / closing knob 25 from the deodorizing material storage unit 24.

  Reference numeral 34 denotes a tip pipe cover screwed to the upper surface of the tip pipe 11, and a thin display sheet 35 is attached so as to cover the red LED 23, the OFF switch 17, and the ON switch 18.

  The operation and action of the vacuum cleaner configured as described above will be described below.

  After the cord 2 plug is connected to the outlet, when the display sheet 35 is pressed and the ON switch 18 is turned on, the electric blower is in an operating state. The airflow including dust on the cleaning surface sucked from the suction tool 15 is sucked into the cleaner body 1 via the extension pipe 13, the tip pipe 11, the hose 4, and the connection pipe 5, and the transferred dust is collected in the dust collecting section. Collected and deposited.

  The user of the electric vacuum cleaner performs an operation of pushing the operation lever 28 toward the inside of the end pipe 11 as shown in FIG. At this time, a predetermined amount of deodorizing material 30 filled in the storage opening 29 of the operation lever 28 falls into the intake passage A19 from the vent 33, and is sucked into the dust collecting portion by the suction airflow and mixed with the dust. The zeolite fine particles constituting the deodorizing material 30 have a large surface area due to the composition having fine voids, and adsorb and contain the odor emitted by dust on this surface, so that it can be reused on the cleaning day or after several days have passed. Even when it is driven, it exerts an effect of reducing the odor from the exhaust of the cleaner body 1 to a level where it can hardly be detected.

  As a control experiment, the deodorizing material 30 is not used as a control experiment, but daily cleaning is performed until dust accumulates in the dust collecting portion (1), and the deodorizing material 30 is supplied to the dust collecting portion every time it is used. Confirmed by comparison with experimental cleaning (2) that is used every day until dust is fully accumulated, and when using zeolite fine particles as deodorizing material, the mass is statistically calculated against 3.2 g / cleaning suction dust. It has been found that a sufficient effect can be obtained by supplying about 0.032 g / time at a ratio of about 1%. In the present embodiment, the storage opening 29 of the operation lever 28 is sized so that approximately 0.032 g of zeolite fine particles can be filled as the deodorizing material 30, and the dust collection dust of the day can be obtained by operating the operation lever 28 once. It can supply the proper amount necessary for deodorization and is very convenient to use.

  As described above, according to the present embodiment, the deodorizing material 30 filled in the deodorizing material storage unit 24 provided in the tip pipe 11 is simply supplied to the dust collecting unit by pushing the operation lever 28, and Since the odor is directly deodorized, it can be deodorized not only at the time of use but also at the time of standing to greatly reduce the exhaust odor. Further, since the deodorizing material 30 is formed into fine particles and disposed in the deodorizing material storage unit 24, the shape of the deodorizing material storage unit 24 can be arbitrarily set, in other words, the installation position of the deodorizing material 30 is difficult. There is nothing.

  In the present embodiment, the fine deodorized zeolite is used as the deodorizing material 30, but the shape is powder and the material is zeolite. However, in addition to zeolite, silica, alumina, activated carbon, etc. may be used as cleaning dust. There is a similar effect that can reduce complex odors, and these may be used as the deodorizing material 30, but among these, the deodorizing effect of zeolite is the highest.

  Further, since the deodorizing material storage section 24 and the vent 33 are arranged on the downstream side of the dust detecting means constituted by the light receiving element 21 and the light emitting element 22, even if the deodorizing material 30 is put into the intake passage A19, the dust detecting means. This function is not impaired.

  Furthermore, the deodorizing material can be charged at the end pipe 11 that is most frequently used by the user, and can be most easily input to the dust collecting unit for the intention of the vacuum cleaner user to supply the deodorizing material. is there.

  Further, since the operating lever 28 and the spring 27 that urges the operating lever 28 so as to always close the opening constitute an opening / closing means for closing the opening 26 so that the user can deodorize. The deodorizing material can be introduced only when the material is intended to be introduced, and when it is not intended, the operating lever 28 returns to the position where the opening 26 is closed by the spring force and the continuous supply of the deodorizing material 30 is eliminated. This configuration can be provided at low cost and at low cost.

  In addition, a storage opening 29 is formed in the operation lever 28 so that a predetermined amount of deodorizing material 30 is filled, and when the deodorizing material is supplied by operating the operation lever 28, the predetermined amount of the deodorizing material 30 is supplied by one operation. Since the deodorizing material 30 is configured to be supplied, it is possible to ensure the ease of use for reliably supplying only the amount necessary for deodorization.

(Embodiment 2)
The vacuum cleaner in the 2nd Embodiment of this invention is demonstrated using FIG. Note that the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 5 is a perspective view showing a connection portion between a tip pipe and an extension pipe of a vacuum cleaner according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view of the extension pipe of the vacuum cleaner.

  5 and 6, the light emitting element storage portion 40 is provided on the lower surface of the tip pipe 11 so as to protrude downward, and the light emitting element, the light emitting element, and the red LED 23 are arranged in the same manner as described in the first embodiment. Detection and notification of dust passing through the intake passage A are performed.

  The elongated extension pipe 41 is formed with an intake passage B42 communicating with the intake passage A in a substantially cylindrical shape, and a lead wire incorporating a pair of lead wires 43 for supplying electric power to the suction tool above the intake passage B42. An extension pipe cover 45 for constituting the storage path 44 is fixed.

  A colorless and transparent flat cylindrical deodorizing material storage portion 24 is disposed on the side of the lead wire storage path 44 close to the tip pipe 11, and an opening 26 is provided at the end of the suction tool side. The deodorizing material 30 colored in a predetermined color is supplied into the deodorizing material storage unit 24 from the supply port 46 exposed to the extension tube cover 45 on the side opposite to the opening 26 and is detachably closed by the opening / closing knob 25. Yes. On the suction tool side of the deodorizing material storage section 24, an operation lever 28 is slidably held in the extension pipe 41 and the extension pipe cover 45 so as to be slidable in the longitudinal direction, and a storage opening 29 is formed in the vicinity of the opening 26. Reference numeral 33 denotes a vent formed in the extension pipe 41 so as to face the opening 26.

  Reference numeral 47 denotes a throttle portion provided on the opening 26 side of the deodorizing material storage portion 24. The deodorizing material 30 moving in the deodorizing material storage portion 24 has a small cross-sectional area at the throttle portion 30 like an intermediate portion of an hourglass. Thus, the moving speed of the deodorizing material 30 is limited.

  When the operation lever 28 is slid in the direction A (ie, in the direction of the suction tool) from the position shown in FIG. 6, the opening 26, the storage opening 29, and the vent 33 are aligned, and the deodorizing material 30 is placed in the intake passage B42. Falls by its own weight. Reference numeral 48 denotes a colorless and transparent see-through window fixed to the extension tube cover 45 in order to check the remaining amount of the deodorizing material 30 in the vicinity of the opening 26.

  The operation and action of the above configuration will be described below.

The user of the vacuum cleaner slides the operation lever 28 toward the suction tool during use to remove the deodorizing material 30.
Is dropped by its own weight into the intake passage B42 and transferred to the dust collecting portion by the suction airflow of the electric blower to deodorize the dust. At this time, since the moving speed of the colored deodorizing material 30 in the deodorizing material storage unit 24 is limited by the throttle unit 47, only the amount that is closer to the opening 26 than the throttle unit 47 is stored in the storage opening 29, It falls to the intake passage B42 through the vent 33, and the operation lever 28 is returned to the original position, that is, the position where the supply of the deodorizing material 30 is stopped, by visually confirming that it has dropped.

  When the deodorizing material 30 in the vicinity of the opening is supplied, the deodorizing material 30 whose movement speed is limited by the throttle portion 47 gradually falls down to the opening 26 side like an hourglass, and is filled. The next supply will be ready.

  The remaining amount of the deodorizing material 30 in the deodorizing material storage unit 24 can be visually confirmed from the transparent window 48. The supply of the deodorizing material 30 can also be confirmed by detecting the fine particles of the deodorizing material 30 by the dust detection means using the light emitting element and the light receiving element arranged on the tip pipe 11 and turning on the red LED 23.

  As described above, in the present embodiment, as shown in FIG. 6, by providing the deodorizing material storage section 26 in the extension pipe 41, the length of the extension pipe is used to increase the cross-sectional area unnecessarily. In particular, since the lead wire storage path 44 is used, the deodorizing material storage section 24 can be formed in a compact manner, and a convenient vacuum cleaner can be provided.

  Further, by forming the deodorizing material storage portion 24 on the upper surface portion of the extension pipe 41, not only can the replenishment of the deodorizing material 30 be performed easily, but also an opening / closing means is formed on the upper surface side of the extension tube 41 to The charging operation can be easily performed.

  Further, by forming the deodorizing material storage portion 24 substantially parallel to the tube axis of the extension pipe 31 and forming the opening 26 on the suction tool side, a reliable intake passage by dropping the deodorizing material 30 by its own weight while maintaining a compact outer shape. Can be input.

  In addition, by forming at least the vicinity of the opening 26 of the deodorizing material storage unit 24 with a transparent member, the remaining amount of the deodorizing material 30 can be easily visually confirmed. When the amount becomes small, the user can be replenished with the deodorizing material 30. By prompting, the deodorizing effect can be realized without interruption. Further, the remaining amount in the deodorizing material storage unit 24 can be easily confirmed by coloring the deodorizing material. These effects are not limited to the case where the deodorizing material storage portion 24 is formed on the extension pipe 41 as shown in the present embodiment, and the vicinity of the opening 26 is substantially transparent and the deodorizing material 30 is colored. Needless to say, this is a common effect.

The opening 26 is formed at the lower end of the deodorizing material storage unit 24 and slightly above the tube axis of the connection tube 50 and is covered with an operation lever 28 so as to be opened and closed.

  When the operating portion 31 of the operating lever 28 is pushed to the intake port 3 side, the opening 26 communicates with the inside of the deodorizing material storage portion 24, and the deodorizing material 30 filled inside falls by its own weight, and a small amount enters the intake passage C53. Each of them is dropped and transferred to the dust collecting part in the vacuum cleaner body 1 by the suction airflow generated by the operation of the electric blower to deodorize the deodorized dust. When the operating part 31 is returned to its original position, the operating lever 28 opens the opening 26. The supply of the deodorizing material 30 is stopped.

  By the way, the connecting pipe 50 is a place connected to the cleaner body 1, and the hose 4, the extension pipe 13, and the suction tool 15 are connected in front of the connection pipe 50, and in particular, compared with the extension pipe 13 and the suction tool 15. Even if the outer shape becomes larger due to the formation of the material storage portion 24, it does not hinder the use, and the deodorizing material storage portion 24 can be formed without worrying about the deterioration in usability.

  Further, since the connecting pipe 50 is connected to the cleaner body 1 and the hose 4 is connected to the suction tool 15 side, the deodorizing material 30 is supplied even when the deodorizing material 30 is supplied in a stopped state of the vacuum cleaner. However, since it is transferred to the dust collecting part by the suction airflow during the next operation, the timing restriction of the deodorizing material can be removed.

  As described above, according to this embodiment, by providing the deodorizing material storage portion in the connecting pipe portion, the influence of the shape and size of the deodorizing material storage portion 24 can be minimized, and the deodorizing material 30 can be charged into the main body. There is also an advantage that can be performed even in a stopped state. Furthermore, by providing the deodorizing material storage portion 24 and the opening 26 above the tube axis of the connecting pipe 50, the deodorizing material 30 falls by its own weight into the connecting pipe 50 from the opening 26, and the direction of the dust collecting portion is simple. The deodorizing material 30 can be replenished easily through the supply port 46 formed in the upper part of the substantially horizontal connecting pipe 50 and has excellent deodorizing ability. It can supply an easy-to-use vacuum cleaner.
