Description

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

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

  However, in the method of installing the deodorization filter in the exhaust path, the suction amount of the vacuum cleaner is large, so the contact time between the deodorization filter and the exhaust air containing odor is shortened, the deodorization efficiency is small, and the odor reduction is small. It had the problem that.

  The present invention solves the above problems, and provides a vacuum cleaner that can significantly reduce the odor of exhaust gas by directly introducing a deodorizing material into the dust collecting part and removing the odor of dust. It is aimed.

  In order to solve the conventional problems, the present invention provides a dust collection unit that collects dust, an electric blower, a power cord winder, and a deodorization of a solid body provided in an upstream portion of ventilation from the dust collection unit. A deodorizing material storage unit for storing the material, a cutting body provided in the deodorizing material storage unit, a pressing body for pressing the deodorizing material against the cutting body, a lid body containing the pressing body, and the cutting A connecting body that connects the body and the power cord take-up device, and the pressing body has a flat surface in contact with the deodorizing material, and is configured to be slidable up and down with respect to the lid body. In conjunction with the winding operation or pulling-out operation of the power cord take-up device, the deodorizing material is directly applied to the sucked dust to strongly remove the odor of the dust and not only during use but also when standing still Can be deodorized, reducing odor retention in the dust collection area, and Even when the initial high odor levels used can be reduced exhaust odor.

In addition, the deodorizing material is supplied as a solid material, so it is easy to handle and is cut by the cutting body by the amount necessary for the amount of dust in a single cleaning operation in conjunction with the winding operation or drawing operation of the power cord winding device. The deodorizing function will not be reduced without frequent replacement.
Furthermore, since the pressing body presses the solid deodorizing material against the cutting body in a flat surface, the deodorizing material can be pressed evenly and always cut into a flat shape, so that cracking occurs even if the deodorizing material becomes thin. Therefore, it is possible to provide a vacuum cleaner with high usability because additional charging is possible.

  The vacuum cleaner of the present invention can be a vacuum cleaner that greatly reduces the odor of exhaust gas by removing the odor of dust by simple means.

  The first invention is a dust collecting unit for collecting dust, an electric blower, a power cord winder, and a deodorizing material storage for storing a solid deodorizing material provided upstream of the dust collecting unit in ventilation. A cutting body provided in the deodorizing material storage section, a pressing body that presses the deodorizing material against the cutting body, a lid body that contains the pressing body, the cutting body, and a power cord winding A connecting body for connecting to the take-off device, and the pressing body has a flat surface in contact with the deodorizing material and is slidable up and down with respect to the lid body. In conjunction with the take-up operation or pull-out operation of the device, the deodorizing material is directly applied to the sucked dust to powerfully remove the odor of the dust and deodorize it not only when it is used but also when it is stationary. Odor retention in the department is reduced, and the first use of a high odor level, especially when using the next vacuum cleaner. It can also reduce the exhaust odor at the time.

  In addition, the pressing force that presses the deodorizing material against the cutting body is applied evenly to the surface of the deodorizing material, the cutting shape is made uniform and the amount of cutting is constant, and at the same time, even if it becomes thin, it does not scrape diagonally. Since the deodorizer is prevented from being damaged and can be continuously cut even if it breaks, the cutting quality can be stabilized and it is easy to use.

  In the second invention, since the pressing body of the first invention is formed with a pressing portion made of an elastic material on the surface in contact with the deodorizing material, the holding force between the pressing body and the deodorizing agent is increased. The deodorization is prevented from changing following the movement of the cutting body, and the cutting effect by the cutting body is enhanced.

  In the third aspect of the invention, in addition to the first or second aspect of the invention, the storage unit is provided with a guide part that holds the lid so as to be slidable in the vertical direction with respect to the deodorizing material. The presser body can come into contact with each other without squeezing, reducing the operating force, preventing cracking of the deodorizer, and maintaining the relative positional relationship between the lid body and the storage portion, so that the structure can be easily attached and detached.

An eccentric gear 34 and a crank arm 35 that mesh with the transmission gear 32 are attached to the gear box 33, and one end of the crank arm 35 is housed in an outer tube 36 that is fixed to the gear box 33 and the housing 30. It is connected to a wire 37 as a connected body. When the flange 22a of the cord reel 22 rotates in conjunction with the drawing operation of the power cord 26, the rotational force is transmitted to the gear 22d, the transmission gear 32, the eccentric gear 34, and the crank arm 35 so as to drive the wire 37 back and forth. It has become.

  Next, the structure of the accommodating part 30 is demonstrated using FIGS.

  The storage unit 30 includes a lower frame 38, an upper frame 39, and a lid 40 made of synthetic resin as main components. A receiving portion 41 formed on the upper frame 39 accommodates a substantially rectangular parallelepiped deodorizing material 42. The deodorizing material 42 is obtained by solidifying powdered activated carbon having an average particle diameter of 20 micrometers with a binder of colloidal silica.

  A pressing body 45 that is urged by a spring 43 and presses and presses the upper surface of the deodorizing material 42 with a flat surface portion 44 is guided by a groove 46 and a projection 47 so as to be slidable up and down. A pressing portion 48 made of an elastic material such as urethane foam rubber is provided on the flat portion 44 so as to form a surface parallel to the flat portion 44 of the pressing body 45. With this configuration, the force of the spring 43 is evenly distributed on the upper surface of the deodorizing material 42 and does not concentrate, so that the deodorizing material 42 can be cut evenly during cutting without being broken or cut while it is tilted. Become. Moreover, since the pressing part 48 adheres to and holds the deodorizing material 42, it generates a holding force larger than the sliding resistance between the deodorizing material 42 and the cutting body. It is possible to prevent the deodorizing material 42 from being displaced during the cutting by the gap generated by the dimensional difference 41 and reducing the cutting amount or colliding with the receiving portion 41 and being damaged.

  As shown in FIG. 7, the lid 40 is held so as to be slidable in the vertical direction by fitting a shaft 51 into a guide 50 formed on the upper frame 39. Further, on both side surfaces of the lid body 40, engaging portions 53 that engage with two engaging claws 52 formed on the upper frame 39 and the engaging claws 52 by a pushing operation as shown in a detailed operation state in FIG. Is released from the engaging portion 53 in a swingable manner. With this configuration, when the lid 40 is opened and closed, the pressing body 45 is not always brought into direct contact with the deodorizing material 42 from above, so that the operating force can be reduced and the deodorizing material 42 can be broken. Absent. Since the lid 40 is always attached to the upper frame 39, it can be easily attached and detached. Furthermore, the engagement body is released by pushing the release body, and the lid body 40 can be opened by lifting it as it is, so that it can be operated by one operation, and at the same time, the usability of the deodorizing material 42 is improved. Since the space is not blocked, a mounting space for the deodorizing material 42 can be secured.

  Further, the lid 40 is rotatable at the upper end of the guide portion 50 by the shaft portion 51, and further contacts the rear end surface 55 of the guide portion 50 as shown in FIG. A lock portion 56 that can be fixed while being tilted is provided, and a restriction portion 58 that sandwiches the front wall 57 of the guide portion 50 is provided below the upper end, so that the lid 40 cannot rotate back and forth with respect to the upper frame 39. It has become. As shown in detail in FIG. 6, the engaging portion is provided with a shave surface 59 that can be self-coupled without relying on an external force immediately before the engagement is completed, and the dust collecting portion cover 20 has a lid as shown in FIG. When the body 40 is closed while being tilted and fixed, it abuts in front of the shaft portion 51 of the lid body 40 and pushes down the lid body 40 beyond the saddle surface 59 of the engaging portion 53. Is formed. With this configuration, the installation space of the deodorizing material 42 can be widened with the lid 40 opened, and it is easy to install, and even if the dust collection cover 20 is accidentally closed with the lid 40 open, it is automatically installed. The lid 40 can be closed without any abnormality, and the usability is extremely high.

  Further, the lid 40 is made of a transparent synthetic resin, and the deodorizing material 42 and the pressing body 45 are colored in different colors such as blue and red. As a result, the remaining amount of the deodorizing material 42 can be confirmed from the front outer side of the lid body 40 by checking the height position of the pressing body 45, and since it is colored, it is visible even if the inner surface of the lid body 40 is dirty. It is expensive.

  The lower frame 38 has two left and right insertion ports 61 that are press-fitted into the packing 31, and the inner surface is inclined with the center at the maximum height so that the maximum inclination angle is obtained toward the insertion port 61. It is composed of planes. The deodorized material thus cut does not remain on the inner surface of the lower frame, but falls to the packing 31 from its insertion port 61 due to its own weight or vibration during traveling, and is introduced into the dust box unit 4 by suction to efficiently exhibit the deodorizing effect. Can do.

  Then, the end portion is fixed to the space formed between the upper frame 39 and the lower frame 38 below the deodorizing material 42 by sandwiching the synthetic resin frame 62 between the claws 63 with the claws 63 (not shown). A cutting body 65 made of the expanded metal 64 is slidably held in the lateral direction. The expanded metal 64 is a general-purpose product and can reduce the manufacturing cost.

  Further, the lower end surface of the lid 40 is flat, and a flat airtight packing body A66 made of an elastic body is fixed to the outside of the receiving portion 41 of the upper frame 39 with an adhesive. The packing body 66 can be produced by a Thomson mold or the like, and the investment cost can be reduced as compared with a mold investment such as insert molding.

  Further, the frame body 62 has a cross section in which one end of the wire 37 is fixed by a ball 67 and a screw 68 and is joined by a cylindrical connecting portion 69, and a packing body having a pressure contact portion 70-1 in pressure contact with the outer periphery of the connecting portion 69. B70 is fixed in pressure contact between the lower frame 38 and the upper frame 39. Reference numeral 71 denotes a switching unit that holds the coupling unit 68 and switches the coupling state of the coupling unit 69 and the frame body 62 to change the displacement amount of the cutting body 65 to adjust the cutting amount. The switching operation unit 71 and the switching operation unit 72 are connected to each other by a spring body (not shown). With this configuration, all the airtightness that leads to the drive unit of the cutting body 65 can be realized only by the packing body B70, and the switching operation part 72 can be minimized outside the packing body B70, and the packing body B70 has a simple shape. Therefore, it is possible to manufacture with a simple mold using an elastomer material, and the investment cost can be minimized. Reference numeral 73 denotes a stainless steel metal plate sandwiched between the frame unit 62 and the lower frame 38 to prevent the deodorizing material from being worn by cutting powder.

  The operation of the above configuration is as follows.

  When the flange 22a of the cord reel 22 rotates in conjunction with the drawing operation of the power cord 26, the rotational force is transmitted to the gear 22d, the transmission gear 32, the eccentric gear 34, and the crank arm 35, and the wire 37 is driven to reciprocate. The part 69 drives the cutting body 65 reciprocally.

  Therefore, the expanded metal 64 constituting the cutting blade reciprocates while cutting the bottom surface of the deodorizing material 42. The cutting powder of the deodorized material that has been cut drops from the opening hole of the expanded metal 64, passes through the frame body 62, and accumulates on the packing 31 from the insertion port 61. When the cleaner body 1 is operated, the granulated deodorizing material 42 accumulated in the packing 31 is sucked from the opening hole 31a provided in the side surface of the packing 31 and sucked into the dust box unit 4 with dust.

  The effect of this invention is investigated using the vacuum cleaner of the above structure.

  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 42 installed in the vacuum cleaner of the present 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 42 clings to the dust as a powder and is mixed with the dust. In this case, a deodorizing material is charged as a powder and is in contact with and mixed with the sucked dust.

Next, after standing for 1 day in this state where 30 g of dust was sucked in, the 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 1.8, while the control experiment was 3.0, confirming a significant odor reduction effect.

  Taking into account that the odor intensity 2 is the threshold for odor recognition, the odor intensity 1.8 is a level at which no smell is detected even if it can be detected as an odor, and the odor can be reduced at a high level. Recognize.

  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 addition, it is possible to provide a cutting mechanism that is simple, small in size, high in cutting performance, and easy to use.

  In the present embodiment, the description has been made mainly on the solid-state deodorizing agent being mainly powdered by the cutting blade, but there is no problem even if it is granular.

  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.

  Moreover, although the wire was illustrated as a connection body which connects a cutting body and a power cord winding apparatus, it is not limited to this, What kind of thing will be used if these can be connected? There is no problem.

  As described above, the vacuum cleaner according to the present invention has a cutting mechanism that is easy to use and has stable cutting conditions, and can remove the odor of dust and greatly reduce the odor of exhaust. Widely applicable to vacuum cleaners.
