Description

  The present invention relates to a vacuum cleaner dust bag and a vacuum cleaner, and more particularly, to deodorization of dust accumulated in the vacuum cleaner dust bag.

As a conventional method for deodorizing dust accumulated in a dust bag for a vacuum cleaner, a paper pack or dust collection filter is impregnated with a deodorizing agent, and the deodorizing agent deodorizes the odor emitted from the dust. Yes (see, for example, Patent Document 1). Moreover, what installed the deodorizing fragrance | flavor in the dust collection indoor space which accommodates the dust collection bag for vacuum cleaners of a vacuum cleaner is proposed (for example, refer patent document 2).
JP-A-5-70871 Japanese Patent No. 2810090

  However, in the conventional deodorization method described in Patent Document 1, since the deodorizer is impregnated only in the filter medium of the paper pack or the dust collection filter, the contact area between the filter medium and the dust is small, and the contact Since the time is instantaneous, there is a problem that a sufficient deodorizing effect cannot be obtained. Therefore, when operating a conventional vacuum cleaner equipped with a paper pack or dust filter, depending on the type and accumulation period of the dust, a bad odor may be mixed with the exhaust air from the vacuum cleaner, which is uncomfortable. there were.

  Moreover, the structure of the conventional vacuum cleaner described in Patent Document 2 is to install a deodorizing fragrance in the dust collection chamber space, so that the deodorant components are scattered in the dust collection chamber, and the vacuum cleaner It is designed to deodorize the dust in the dust bag and relieve the exhaust odor during operation. However, the deodorant fragrance mixes a fragrance with the odor of the dust to mitigate the exhaust odor. However, there has been a problem that the fundamental odor cannot be removed, and depending on the type of dust sucked, the vacuum cleaner exhausts it as an unpleasant odor.

  Further, in the conventional configuration, in the dust bag type vacuum cleaner that can suck in a large amount of dust and hold the dust for a long time, almost all of the suction airflow passes through the dust, so the amount of dust absorption increases. Therefore, the amount of odor generation increases, and in the state close to the permissible amount of the dust bag, the generation of odor significantly increases.Therefore, the deodorizing effect of the deodorant fragrance has almost no effect. It was.

  The present invention solves the above-described conventional problems, and greatly reduces the odor derived from dust contained in the exhaust when using the vacuum cleaner, regardless of the amount of dust in the dust bag for the vacuum cleaner and the storage period. An object of the present invention is to provide a dust bag for an electric vacuum cleaner and an electric vacuum cleaner that are easy to use.

  In order to solve the above-described conventional problems, a dust collection bag for a vacuum cleaner according to the present invention has an opening for dust suction, a mouthpiece mounted in the cleaner, and suction from the opening of the mouthpiece. A bag-like body for collecting the collected dust, a storage case storing granular or powdery deodorant, and a discharge port provided in the storage case and communicating with the opening of the wick and discharging the deodorant And a thin plate-like member having a handle portion at one end in a substantially band shape, and the member is bonded to the storage case via an adhesive portion so that the end portion on the opposite handle portion side is covered with a part of the member. When using a vacuum cleaner dust bag, pulling the handle part of the member and peeling the member from the storage case, the outlet is easily exposed and the vacuum cleaner is operated. Sometimes, particles in the storage case are sucked by dust when sucking dust. Alternatively, the powdery deodorant is discharged from the discharge port, which is mixed with the sucked dust and deposited in the bag-like body, so that the contact area between the dust and the deodorant is extremely wide, and the deodorant is Since the vacuum cleaner dust collection bag remains until it is discarded or the bag-like body is emptied, the deodorizing effect can be maintained for a long time, so that the cleaning can always be performed comfortably. In addition, since a part of the thin plate-like member covers the end of the member, it can be easily bonded to the storage case regardless of the shape of the discharge port, and the deodorizer can be removed from the storage case during transportation. Will not leak out and will not interfere with the use of the vacuum cleaner dust bag.

  Moreover, the vacuum cleaner of this invention is for attracting | sucking air in the dust collection chamber with which the dust collection bag for vacuum cleaners of any one of Claims 1-3 is mounted | worn, and the said dust collection chamber A vacuum cleaner that is equipped with an electric blower and that exhibits excellent deodorizing performance over a long period of time and can be used comfortably at all times can be provided.

  The vacuum cleaner dust bag and vacuum cleaner according to the present invention greatly reduce the occurrence of dust-derived odors in the exhaust gas, and long-term until the dust in the vacuum cleaner dust bag reaches an allowable amount. The deodorizing effect can be maintained over the range.

  1st invention has the opening part for dust suction, and the opening | mouth core with which it installs in a vacuum cleaner, the bag-shaped body which collects the dust attracted | sucked from the opening part of the said opening | mouth core, granular or powdery form A storage case storing the deodorant, a discharge port that is provided in the storage case and communicates with the opening of the mouth core and discharges the deodorant, and a thin plate-like member having a strip shape and having a handle at one end.

When using the bag, pulling the handle of the member and peeling the member from the storage case, the discharge port is easily exposed, and when operating the vacuum cleaner, the dust inside the storage case can Powdered deodorant is discharged from the outlet, The dust and deodorant contact area is very wide, and the deodorizer is discarded in the vacuum cleaner dust bag or empty in the bag. Since the deodorizing effect is great and can last for a long time, the cleaning can always be performed comfortably. In addition, since a part of the thin plate-like member covers the end of the member, it can be easily bonded to the storage case regardless of the shape of the discharge port, and the deodorizer can be removed from the storage case during transportation. Will not leak out and will not interfere with the use of the vacuum cleaner dust bag.

  In the second invention, in particular, the member of the first invention is provided with an adhesive portion at least at a portion covering the discharge port, and no adhesive portion is provided at the other portion. When transporting, the discharge port is securely closed by the adhesive part of the member, so that the deodorant does not leak out, and when using the vacuum cleaner dust bag, pull the handle to remove the member. Since there is no adhesive part at the extra place when peeling, it can be peeled with a light force.

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

(Embodiment 1)
FIG. 1 is an exploded perspective view of a vacuum cleaner dust bag in the first embodiment of the present invention, FIG. 2 is a perspective view of members of the vacuum cleaner dust bag, and FIG. Sectional drawing of the storage case of the vacuum cleaner dust collecting bag, FIGS. 4 and 5 are main part sectional views of the dust collecting bag for the vacuum cleaner, and FIG. 6 shows the electricity equipped with the dust collecting bag for the vacuum cleaner. It is a whole perspective view of a vacuum cleaner.

  1 to 5, a vacuum cleaner dust collecting bag 1 (hereinafter referred to as “dust collecting bag 1”) in the present embodiment has an opening 2a for sucking dust, and is made of a paper material or a resin material. A wick 2, a storage case 3 that is attached to the back surface of the mouth wick 2 (the surface that is downstream of the suction air when attached to a vacuum cleaner) and that stores granular or powdery deodorant 3 a, and the front surface Has a suction port 4a for sucking dust, and is composed of a bag-like body 4 formed in a bag shape with a filter medium made of paper or cloth. In the present embodiment, the bag-like body 4 is formed of a paper material, and is attached to the back surface of the storage case 3 by adhesion.

  The storage case 3 includes an opening 3b communicating with the opening 2a. The storage case 3 forms the opening 3b and is stored on the inner peripheral surface 3c parallel to the flow of suction air flowing from the opening 2a of the wick 2. The interior of the case 3 and the opening 2a of the wick 2 are communicated with each other, and a discharge port 3d through which the deodorant 3a stored inside is discharged is provided. In addition, a lid 3e that is closed after the deodorizing agent 3a is introduced into the storage case 3 is provided at the upper end of the storage case 3 (FIG. 1 shows a state in which the lid 3e is closed).

  When the dust bag 1 is assembled, it goes without saying that the opening 2a of the mouthpiece 2, the opening 3b of the storage case 3, and the suction port 4a of the bag-like body 4 communicate with each other. It is attached to match.

  A member 5 is bonded to the inner peripheral surface 3c of the storage case 3 so that the deodorizer 3a does not leak from the discharge port 3d of the storage case 3 when the dust bag 1 is transported. The member 5 is formed of a thin plate-like material that is substantially band-shaped and easily deformed, such as paper or synthetic paper, and is provided with a handle portion 5b that can be picked and pulled by a finger when removing the member 5 at one end. In addition, the adhesive part 5c is arranged on the part to be bonded to the storage case 3, particularly the part that seals the discharge port 3d, and the other part including the handle part 5b is not provided with the adhesive part 5c. That is, the desizing part 5d is arranged.

  When the member 5 is affixed to the inner peripheral surface 3c of the storage case 3, as shown in FIGS. 2 and 3, first, the end 5e of the member 5 on the side opposite to the handle 5b is connected to the inner peripheral surface via the adhesive portion 5c. 3c, and then pasted along the inner peripheral surface 3c so that each discharge port 3d is hermetically sealed with another bonding portion 5c. Finally, the end portion 5e was covered with a part of the member 5. Thereafter, the handle 5b is bent so as to rise upward, and the attachment is completed. In the present embodiment, the portion covering the end portion 5e of the member 5 is provided with a paste removal portion 5d, that is, a portion without the adhesive portion 5c.

  As described above, according to the present embodiment, the storage case 3 is provided with the thin plate-like member 5 for preventing the deodorant 3a from leaking during transportation so as to cover the discharge port 3d with the adhesive portion 5c. Therefore, the deodorizing agent 3a does not leak from the discharge port 3d when the dust bag 1 is used before being used, and there is no problem when the dust bag for the vacuum cleaner is used.

  When the dust bag 1 is attached to a predetermined location of the vacuum cleaner, the upward handle portion 5b of the member 5 is pulled up with the dust bag 1 attached to the vacuum cleaner body 6. As a result, the adhesive portions 5c are peeled off sequentially, the discharge port 3d of the storage case 3 is opened, and finally the member 5 can be easily removed from the storage case 3.

  Further, by providing the handle portion 5b of the thin plate-like member 5 substantially above the bonding portion 5c, it becomes easy to move the handle portion 5b upward in order to peel off the bonding portion 5c.

  Further, by covering the end portion 5e opposite to the thin plate-shaped handle portion 5b with the same member 5, the inner peripheral surface 3c can be completely sealed with only one member 5. Thereby, the deodorizing agent 3a can be reliably enclosed in the storage case 3 regardless of the shape of the discharge port 3d provided in the inner peripheral surface 3c.

  Further, by providing the desizing part 5d in a part covering the end part 5e of the member 5, the area of the adhesive part 5c can be reduced and the force to peel off the member 5 on the thin plate can be reduced while sealing the discharge port 3d. .

  Further, by providing the paste removing portion 5d on the curved surface portion, it is possible to easily peel off the adhesive portion 5c even on the curved surface portion where the force is not easily transmitted when the handle portion 5b is pulled upward.

  In the present embodiment, zeolite that is easy to handle is used as the deodorizer 3a.

  With the above configuration, when the dust bag 1 is packed, by covering the discharge port 3d provided in the storage case 3 with the thin plate-like member 5 formed of paper having the adhesive portion 5c or synthetic paper, Since the deodorizer 3a does not leak from the storage case 3 when the dust bag 1 is transported, there is no problem when the dust bag 1 is used.

  Next, a vacuum cleaner to which the dust bag 1 according to the present embodiment is attached will be described with reference to FIG.

  The electric vacuum cleaner body 6 (hereinafter referred to as “vacuum cleaner body 6”) is provided with a pair of traveling rear wheels 7 at the rear and a traveling front wheel caster 8 at the front. An intake port 10 communicating with a dust collection chamber described later is provided on the front surface of the cleaner body 6, and a connection pipe 11 a provided at one end of the hose 11 is connected to the intake port 10, and the other end of the hose 11 is connected to the other end of the hose 11. A tip pipe 11b that is operated when using the electric vacuum cleaner is provided. Further, the tip pipe 11 b is connected to the floor suction tool 13 via the extension pipe 12.

  Next, the operation and operation of the electric vacuum cleaner equipped with the dust bag 1 in the present embodiment will be described.

  When a plug (not shown) of a power cord (not shown) derived from the cleaner body 6 is inserted into a wall outlet (not shown) and the switch 11c provided on the tip pipe 11b is operated, an electric blower (not shown) ) Starts, and the generated suction force acts on the suction port (not shown) provided on the bottom surface of the floor suction tool 13 through the hose 11 and the extension pipe 12, and together with the surrounding air, Dust on the floor is sucked.

  The air that flows in from the suction port of the floor suction tool 13 becomes suction air and passes through the extension pipe 12, the hose 11, and the suction port 10 together with dust, and then the opening 2 a of the wick 2 and the opening 3 b of the storage case 3. Then, the air flows into the bag-like body 4 through the suction port 4a of the bag-like body 4, dust is collected there, and the clean air passes through the electric blower 16 and is arranged in the rear part of the cleaner body 6. From the exhaust port (not shown).

  Then, when the suction air containing dust passes through the opening 3b of the storage case 3, as shown in FIG. 5, a suction force due to the ejector effect acts in the storage case 3 through the discharge port 3d. The stored granular or powdery deodorant 3a is discharged, and the discharged deodorant 3a enters the bag 4 while being mixed with dust, and accumulates from the back side (electric blower side).

  At this time, when the dust is observed microscopically, since the outer periphery of each dust is surrounded by a granular or powdery deodorant 3a, the contact area between the dust and the deodorant 3a becomes extremely large, And in the dust bag 1, dust is hold | maintained in the form enclosed with the deodorizing agent 3a. As a result, the deodorizing effect of the deodorizing agent 3a is exhibited without regret, and the odor is greatly reduced. For example, a collection of hair of dogs and cats with strong odors was sucked and the smell of exhaust air from the vacuum cleaner main body 1 was sniffed, but the smell was reduced to such an extent that it was hardly felt.

  In addition, the deodorizing agent 3a remains with the dust until the dust bag 1 is discarded or the bag-like body 4 is emptied. Therefore, the deodorizing agent 3a has a large deodorizing effect and can be maintained for a long time. Can do.

  The deodorizing agent 3a should be set to have a particle size or powder size larger than the pores through which the air of the bag-like body 4 passes (the gap between the fibers of the paper material and cloth material forming the bag-like body 4). For example, the deodorizing agent 3a sucked together with the dust does not pass through the pores of the bag-like body 4, and the deodorizing effect of the deodorizing agent 3a can be maintained for a long period of time.

  Further, if the zeolite forming the deodorizing agent 3a is subjected to hydrophobic processing, the granular or powdery zeolite sucks in the surrounding moisture when the dust bag 1 is stored or used, and becomes a dumpling. The deodorizing agent 3a is not discharged from the outlet 3d of the storage case 3 and the deodorizing performance is not deteriorated.

  In this embodiment, since the storage case 3 is provided on the downstream side of the core 2, the storage case 3 can be used for a vacuum cleaner that uses a conventional dust bag without the storage case 3. The compatibility is excellent and the manufacture and inventory management of the dust bag 1 are simplified.

  In addition, by forming each of the mouthpiece 2, the storage case 3, and the bag-like body 4 from a combustible material, when the dust bag 1 is discarded, it is not necessary to separate the materials and can be discarded as ordinary burning garbage. So clean up is easy and hygienic.

  Moreover, if paper is used as the combustible material, the material cost is low, a molding die is not required, the mass productivity is excellent, and the total cost can be greatly reduced.

  Furthermore, if anti-static processing is applied to the granular or powdery deodorant 3a, the granularity in the storage case 3 can be obtained when the dust bag 1 is transported or when the cleaner body 6 with the dust bag 1 is moved or used. Alternatively, even if powdery deodorizers rub against each other due to vibration, they do not generate static electricity, so that they do not stick to each other and do not easily come out from the discharge port 3d, and can always exhibit an excellent deodorizing effect.

  Further, by providing the discharge port 3d on the surface of the storage case 3 parallel to the inflowing air flow, the granular or powdery deodorant 3a in the storage case 3 is sucked by the suction effect of the suction air ejector. Without being interrupted from the discharge port 3d, it is discharged efficiently and a high deodorizing effect can be exhibited. Further, since the ejector effect changes according to the suction flow velocity, the ejector effect is large when the suction air volume is large (the amount of dust suction is large), and is small when the suction air volume is small (the amount of dust suction is small). That is, since the supply amount of the deodorizing agent 3a automatically changes according to the amount of dust absorption, the deodorizing effect can be exhibited effectively without waste.

  In this embodiment, the bag-like body 4 is attached to the back surface of the storage case 3, but it may be attached to the back surface of the wick 2 by bonding or the like, considering the cost and the assembly of the dust bag. Therefore, it can be determined as appropriate.

  In the present embodiment, the bag-like body 4 is formed of a paper material. However, the bag-like body 4 is formed of a cloth material, and a waste disposal opening (not shown) for dust disposal that can be freely opened and closed is provided at the downstream end portion. When the body 4 is filled with dust, the waste opening may be opened, the dust inside may be discarded, and used again. In this case, it is necessary to replenish the storage case 3 with the deodorant 3a every time the dust is discarded or every several times the dust is discarded. However, it is preferable to replenish the deodorant 3a as necessary. Further, if the storage case 3 is made of a transparent or translucent material, the remaining amount of the internal deodorant 3a can be easily seen from the outside, so that the deodorant 3a is not cut off during use and is easy to use. improves.

  As described above, the storage case 3 is formed of a transparent or translucent material, and a light emitting element (not shown) and a light receiving element (not shown) are opposed to each other before and after the portion containing the deodorant 3a. If it is provided and the remaining amount of the deodorant 3a is detected and the remaining amount is reduced, the user can be notified of this by sound, light, vibration, or the like, which further improves usability.

  In addition, by using the dust bag 1 described in the first embodiment for a vacuum cleaner, excellent deodorizing performance can be demonstrated over a long period of time, and the cleaning operation can be performed comfortably and happily at all times. Is.

  In the above embodiment, zeolite is used as the deodorizing agent 3a. However, activated carbon having an adsorbing effect on various odors such as lower fatty acids, ammonia and aldehydes, which are odorous substances derived from dust, is used by using an adsorbent. It may be used.

  Furthermore, it is also possible to mix an antibacterial agent or a fragrance with the deodorant 3a. As the antibacterial material of the antibacterial agent, silver, zinc, copper, and organic types such as allyl isothiocyanate, catechins, etc. are used as an inorganic type. In particular, silver is particularly preferred in that it exhibits a high antibacterial effect in a small amount, and it can obtain a bactericidal action as well as deodorization, thereby improving safety.

  By the way, when the vacuum cleaner is left for a long time due to a long trip or the like, when cleaning is performed, the deodorant 3a in the storage case 3 is hardened by moisture absorption, and the deodorant 3a may not be discharged smoothly. In order to solve this, a vibration means (not shown) that forcibly applies vibration to the storage case 3 may be provided, and this vibration means may be operated when the operation of the cleaner body 6 starts. Although not specifically shown, the vibration means is formed of a vibration element that vibrates electrically, a vibrating body that mechanically interlocks with the operation of pulling out the power cord or the rotation of the rear wheel 7 and that vibrates the storage case 3. Good.

  Further, if vibration means for applying vibration to at least a part of the bag-like body 4 of the dust bag 1 is provided and the vibration means is operated periodically or irregularly, the dust in the bag-like body 4 And the deodorizing agent 3a are shaken, the contact state between them is changed, and deodorization can be performed more effectively.

  The vibration means for applying vibration to the bag-like body 4 may have the same configuration as the vibration means for applying vibration to the storage case 3 described above.

  As described above, the dust bag for vacuum cleaner and the vacuum cleaner of the present invention drastically increase the contact area and contact time between dust and deodorant compared with the conventional one, and as a result, the deodorizing effect is remarkably good. The present invention is not limited to a vacuum cleaner, and can be widely applied to various devices such as a garbage disposal machine that emits odors.
