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 described in patent document 2 installs a deodorizing fragrance | flavor in dust collection room space, disperses a deodorizing component in a dust collection room, and is a dust collection bag for vacuum cleaners. Although deodorizing is performed to reduce the exhaust odor during operation, the deodorant fragrance mixes a fragrance with the odor of the dust to reduce the exhaust odor. However, depending on the type of dust that was sucked, there was a problem that it was exhausted from the electric vacuum cleaner as an unpleasant odor.

  In addition, in a dust bag vacuum cleaner that can suck in a large amount of dust and hold it for a long time, almost all of the suction airflow passes through the dust, so the amount of odor generated increases as the amount of dust accumulated in it increases. In particular, in the state close to the permissible amount of the dust bag, the generation of odor is greatly increased, so that the deodorant effect of the deodorant fragrance is hardly obtained.

  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.

By the suction air at the time of dust suction, the granular or powdery deodorant in the storage case is discharged from the discharge port of the storage case, and it is mixed with the sucked dust and accumulated in the bag-like body, The contact area between dust and deodorant is extremely large, and the deodorizer remains until the vacuum cleaner dust bag is discarded or the bag-like body is emptied. So you can always clean comfortably. Also, since the case for storing the deodorant is detachable from the wick, only the storage case containing the deodorant can be replaced, and if the bag is full without using up the deodorant, or the bag Even when only the deodorizer is exhausted before the battery becomes full, the deodorizer or the bag-like body can be effectively used until the end by replacing only the storage case containing the deodorizer.

FIG. 1 is an exploded perspective view of the vacuum cleaner dust bag in the first embodiment of the present invention, and FIG. 2 is a perspective view of the storage case of the vacuum cleaner dust bag.

  In FIG. 1, 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 a wick 2 made of a paper material or a resin material. A storage case 3 for storing granular or powdery deodorant 3a on the back surface of the mouthpiece 2 (the surface downstream of the suction air when attached to a vacuum cleaner), and dust suction on the front surface And 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 detachably attached to the back surface of the storage case 3.

  In this embodiment, the detachable configuration of the wick 2 and the storage case 3 and the detachable configuration of the storage case 3 and the bag-like body 4 are formed by hook-and-loop fasteners (not shown), but are repeatedly bonded. An adhesive that can be used may be used. In short, any adhesive may be used as long as it is detachable.

  In FIG. 2, the storage case 3 includes an opening 3 b that communicates with the opening 2 a (see FIG. 1) of the wick 2, forms the opening 3 b, and sucks air that flows from the opening 2 a of the wick 2. The inner peripheral surface 3c parallel to the flow is provided with a discharge port 3d through which the inside of the storage case 3 communicates with the opening 3b and through which the deodorant 3a stored therein is discharged. 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 (the figure shows a state in which the lid 3e is opened).

  Needless to say, when assembling the dust bag 1, the opening 2 a of the wick 2, the opening 3 b of the storage case 3, and the suction port 4 a of the bag-like body 4 are aligned with each other. Let it be attached.

  In the present embodiment, zeolite that is easy to handle is used as the deodorizer 3a. Next, a vacuum cleaner to which the dust bag 1 according to the present embodiment is attached will be described with reference to FIGS.

  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 15 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. Is provided with a tip pipe 11b which is operated when the vacuum cleaner is used. Further, the tip pipe 11 b is connected to the floor suction tool 13 via the extension pipe 12.

  In FIG. 4, a dust collection chamber 15 in which the dust bag 1 is detachably stored in the front portion of the cleaner body 6 and is covered with a dust collection lid 14 so as to be opened and closed is electrically driven to generate suction air at the rear portion. An electric blower chamber 17 that houses the blower 16 is disposed on the back side, and an exhaust port 19 that communicates the electric blower chamber 17 with the outside and exhausts exhaust air from the electric blower 16 is disposed on the back surface. Reference numeral 18 denotes a partition wall that partitions the dust collection chamber 15 and the electric blower chamber 17, and is provided with a lattice-shaped opening 18 a that communicates the dust collection chamber 15 and the electric blower chamber 17.

  A packing 20 made of an elastic material such as rubber, vinyl chloride, or silicone and having an annular lip 20a at the rear is provided at the rear end of the air inlet 10 provided at the front of the cleaner body 6. To attach the dust bag 1 to the cleaner body 6 in the present embodiment, first, the lower end of the mouthpiece 2 of the dust bag 1 is inserted into the groove 22 provided at the bottom of the cleaner body 6, The upper end is completed by being hooked on a hook 23 provided on the cleaner body 6 so as to be tiltable. In the state where the wick 2 is attached at a predetermined position, the lip 20a of the packing 20 is pressed against the peripheral edge of the opening 2a of the wick 2 so as to keep airtight.

  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) led out 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, the electric blower 16 is operated. The suction force generated thereby acts on a suction port (not shown) provided on the bottom surface of the floor suction tool 13 via the hose 11 and the extension pipe 12, and together with the surrounding air, dust on the floor surface 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. Through the suction port 4a of the bag-like body 4, it flows into the bag-like body 4, where dust is collected, and clean air is discharged from the exhaust port 19 to the outside through the electric blower 16. The

  When the suction air containing dust passes through the opening 3b of the storage case 3, a suction force due to the ejector effect acts in the storage case 3 through the discharge port 3d, so that the granular or powder stored inside The deodorizing agent 3a is discharged, and the discharged deodorizing agent 3a enters the bag-like body 4 while being mixed with dust, and accumulates from the back side (electric blower 16 side).

  When the appearance of the dust flowing into the bag-like body 4 is observed microscopically, since the outer periphery of each dust is surrounded by a granular or powdery deodorizing agent 3a, the dust and the deodorizing agent 3a The contact area is extremely large, and the dust is stored in the dust bag 1 as if the dust is surrounded by 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 hairs of dogs and cats with strong odors was sucked and the smell of exhaust air from the vacuum cleaner body 6 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.

  Moreover, since the storage case 3 is provided in the downstream of the wick 2, the dust bag 1 in this Embodiment is also used for the vacuum cleaner which uses the conventional dust bag which is not equipped with the storage case 3. Since it can be used, the compatibility is excellent, and the manufacture and inventory management of the dust bag 1 are simplified.

  In addition, in the said embodiment, although the bag-like body 4 was attached to the back surface of the storage case 3, you may attach to the back surface of the wick 2 so that attachment or detachment is possible, and the cost and the assembly property of the dust bag 1 are considered. It is determined as appropriate.

  In the above embodiment, the storage case 3 is detachable from the back surface of the wick 2. However, as shown in FIG. 5, it may be detachable from the upstream side of the wick 2, that is, from the front side. In this case, it is only necessary to add a process of attaching the storage case 3 after the production process of the conventional dust bag 1, so that the capital investment is greatly suppressed, and the storage case 3 is also in front of the user and can be easily replaced. become.

  Moreover, in the said embodiment, although the bag-like body 4 was formed with the paper material, it formed with the cloth material, and also provided the waste disposal opening (not shown) for dust disposal which can be opened and closed in the downstream end part, When the state 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, and it is possible to prevent the replenishment of the deodorant 3a. Usability is improved without being cut.

  Further, if the storage case 3 is provided on the upstream side of the core 2 and the upstream surface (lip 20a side) of the storage case 3 is formed of a transparent or translucent material so that the inside can be seen through, the internal deodorizer Since the remaining amount of 3a is easily seen from the outside, the deodorizer 3a is not cut off during use, and the usability is improved.

  Further, as shown in FIG. 6 (a), the storage case is formed of a transparent or translucent material, and a scale line 3f is applied to the inside of the storage case 3 as a marking indicating the remaining amount of the deodorant 3a. By doing so, the remaining amount of the deodorant 3a can be determined at a glance.

  In addition, by using a color with a strong warning, such as red, on the lower side of the scale line 3f, the user can be informed that the amount of the deodorant 3a is small and can be cleaned with the deodorant 3a cut off. There is an effect to prevent to do.

  Further, as shown in FIG. 6B, if the marking 3g is written in the lower part of the storage case 3 in a color different from that of the internal deodorant 3a, the marking 3g is removed when the deodorant 3a falls below a certain amount. Thus, the user can be more easily informed that the amount of the deodorizing agent 3a is small. Furthermore, it becomes easier to understand by using a color with a strong warning, such as red, as the color of the marking 3g.

  Further, a light emitting element (not shown) and a light receiving element (not shown) are provided opposite to each other before and after the portion of the storage case 3 made of a transparent or translucent material containing the deodorant 3a, and the deodorizer 3a. If the remaining amount is detected and the amount is reduced, the fact is notified to the user by sound, light, vibration, etc., and the usability is further improved.

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

  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 fragrance with the deodorizer 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 preferable in that it exhibits a high antibacterial effect even in a small amount, and it can obtain a bactericidal action as well as deodorization and can improve 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 vacuum cleaner dust bag and the vacuum cleaner according to the present invention have dramatically increased contact area and contact time between the dust and the deodorizing agent as compared with the conventional case, and as a result, the deodorizing effect is remarkably good. Therefore, the present invention can be applied not only to a vacuum cleaner but also to various devices such as a garbage disposal machine that emits an odor.
