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 a 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. It is designed to deodorize and relieve exhaust odor during operation. However, deodorant fragrance mixes a fragrance with the odor of dust to mitigate 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.

  Further, in the conventional configuration, in the dust bag vacuum cleaner that can suck a large amount of dust and hold it for a long time, almost all of the suction airflow passes through the dust, so odor is generated as the amount of dust absorption increases. In the state where the amount increases and the dust bag is close to the allowable amount, the generation of odor is greatly increased, so that the deodorizing effect of the deodorant fragrance hardly has an effect.

  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. An opening that collects the collected dust and has a suction port on the front surface, and is held between the mouth core and the bag body and communicates with the opening of the mouth core and the suction port of the bag body A deodorizer on the inner peripheral surface of the opening of the storage case parallel to the flow of air flowing in from the opening of the core. Rutotomoni provided an outlet for discharging a part of the housing case, to protrude inwardly from the periphery of the opening of the mouth core downstream side of the projecting portion, a discharge port for discharging the deodorant those formed by extending, by suction air during dust suction, particulate in the storage case or powdery deodorant As it is discharged from the storage case and mixed with the sucked dust and accumulates in the bag-like body, the contact area between the dust and the deodorant is extremely wide. Since it remains until it is discarded or the bag-like body is emptied, the deodorizing effect is large and it can last for a long time, so that it can always be comfortably cleaned.

  The vacuum cleaner of the present invention comprises a dust collection chamber in which the dust bag for the vacuum cleaner is mounted, and an electric blower for sucking air into the dust collection chamber, and has excellent deodorizing performance. Can be used for a long period of time and can always be used comfortably.

  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 collects the dust attracted | sucked from the opening | mouth core with which the opening part for a vacuum cleaner is equipped while having an opening part for dust suction | inhalation, and the opening part of the said wick, and has a suction opening in the front surface A body, the mouth core and the bag-like body, having an opening communicating with the opening of the mouth core and the suction port of the bag-like body, and containing a granular or powdery deodorant therein and a storage case, parallel to the flow of the air flowing from the opening of the port core, the opening peripheral surface of the storage case, Rutotomoni provided a discharge port for discharging the deodorant, a portion of the storage case Is protruded inward from the peripheral edge of the opening of the wick, and a discharge port for discharging the deodorant is extended on the downstream side surface of the protrusion , and by suction air at the time of dust suction, The granular or powdery deodorant in the storage case is discharged from the storage case, and it is sucked dust. By mixing and depositing in the bag-like body, the contact area between the dust and the deodorant is extremely wide, and the deodorant remains until the vacuum cleaner dust bag is discarded or the bag-like body is emptied. As a result, the deodorizing effect is great and it can be maintained for a long time, so that it can always be comfortably cleaned. Further, the granular or powdery deodorant in the storage case is efficiently discharged without interruption from the discharge port due to the suction action by the ejector effect of the suction air, and a high deodorizing effect can be exhibited. Further, since the ejector effect of the suction air changes in accordance with the suction flow velocity, it increases when the suction air amount is large (the dust absorption amount is large) and decreases when the suction air amount is small (the dust suction amount is small). That is, since the supply amount of the deodorizer automatically changes according to the dust absorption amount, the deodorization effect can be effectively exhibited without waste. In addition, in the protruding part, the inflowing air smoothly flows on the inner peripheral surface of the opening of the storage case without being obstructed by the opening edge of the opening of the wick, and the ejector effect is satisfactorily generated. The deodorizer is discharged well from the discharge port provided on the inner peripheral surface of the opening. Moreover, by extending the discharge port for discharging the deodorant to the downstream side surface of the protruding portion, the deodorant can be discharged more smoothly and effectively, and a higher deodorizing effect can be exhibited. become.

  The second invention comprises a dust collection chamber in which the vacuum cleaner dust collection bag of the first invention is mounted, and an electric blower for sucking air into the dust collection chamber, and has excellent deodorizing performance. Can be provided over a long period of time, and a vacuum cleaner that can always be used comfortably can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

FIG. 1 is a developed perspective view of a dust bag for a vacuum cleaner according to the present invention, FIG. 2 is a perspective view of a storage case of the dust bag for the vacuum cleaner, and FIG. 3 is a dust collection for the vacuum cleaner. FIG. 4 is a cross-sectional view of the main body of the vacuum cleaner, FIG. 4 is a cross-sectional view of the main part of the vacuum cleaner.

  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. And a storage case 3 that is attached to the back surface of the mouthpiece 2 (the surface that is downstream of the suction air when mounted on a vacuum cleaner) and that stores granular or powdery deodorant 3a, and dust on the front surface. It has a suction port 4a for suction, and is composed of a bag-like body 4 formed into 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.

  In FIG. 2, the storage case 3 includes an opening 3 b, and the storage case 3 is formed on the inner peripheral surface 3 c that forms the opening 3 b and is parallel to the flow of suction air flowing from the opening 2 a of the wick 2. A discharge port 3d is provided through which the interior of the interior and the opening 3b communicate with each other and the deodorizing agent 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, the 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.

  As shown in FIG. 4, the vacuum cleaner main body 1 accommodates the dust collection bag 1 so as to be attachable to the front, and a dust collection chamber 15 which is covered with a dust collection lid 14 so as to be opened and closed. The electric blower chamber 17 for storing the electric blower 16 to be generated is provided with an exhaust port (not shown) through which the electric blower chamber 17 and the outside communicate with each other on the back surface and exhaust air from the electric blower 16 is discharged. 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 the clean air is discharged from the exhaust port to the outside through the electric blower 16. .

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 mixes with dust and enters the bag-like body 4 and accumulates from the back side (electric blower 16 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.

  Furthermore, the particle size or powder diameter of the deodorizing agent 3a is set 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 the cloth material forming the bag-like body 4). Therefore, 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 by 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. Therefore, the deodorizing agent 3a is not discharged from the outlet 3d of the storage case 3 and the deodorizing performance is not lowered.

  In addition, by providing the storage case 3 on the downstream side of the wick 2, it can be used for a vacuum cleaner using a conventional dust bag without the storage case 3, and has excellent compatibility. Manufacturing 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.

  In addition, if paper is used as the combustible material, the material cost is low, and a molding die is unnecessary, so that 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 outlet 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. In addition, 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 dust suction amount 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 is effectively exhibited without waste.

  In this embodiment, the bag-like body 4 is attached to the back surface of the storage case 3, but may be attached to the back surface of the wick 2 by bonding or the like, taking into account cost and assembly of the dust bag. It is 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. Furthermore, 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 the usability is improved. To do.

  As described above, if the storage case 3 is formed of a transparent or translucent material, 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 the remaining amount of the deodorizing agent 3a is detected, and the amount of the deodorant 3a is reduced, the user can be notified of this by sound, light, vibration, or the like.

(Embodiment 2)
FIGS. 6A and 6B are a plan view and a cross-sectional view of relevant parts of a dust bag in the second embodiment of the present invention. Note that the same portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the present embodiment, as shown in FIGS. 6A and 6B, at least a part of the inner peripheral edge of the opening 3 b of the storage case 3 protrudes inward from the peripheral edge of the opening 2 a of the wick 2. The air inlet 3g is provided on the upstream side surface of the protruding portion 3f.

  With the above configuration, since at least a part of the inner peripheral edge of the opening 3b of the storage case 3 protrudes inward from the peripheral edge of the opening 2a of the wick 2, the opening 2a of the wick 2 is formed in this protruding portion. The inflowing air flows smoothly through the inner peripheral surface 3c of the opening 3b of the storage case 3 without being obstructed by the opening edge, so that the ejector effect is favorably generated, and the inner peripheral surface of the opening 3b of the storage case 3 The deodorizing agent 3a is discharged well from the discharge port 3d provided in 3c.

  In addition, since a part of the air flowing in from the opening 2a of the core 2 flows into the storage case 3 from the air inlet 3g, the deodorizing agent 3a is discharged more effectively and reliably and is high. Deodorizing effect can be exhibited. In the present embodiment, as shown in the drawing, the discharge port 3d is extended to the side surface of the protruding portion 3f to form the air inlet 3g, but the discharge port 3d and the air inlet 3g are formed separately. You may do it.

  Further, as shown in FIG. 6B, the storage case 3 is provided with a discharge port 3d provided on a surface parallel to the inflowing air flow, on the downstream side surface of the protruding portion 3f. The deodorizing agent 3a from 3 is discharged more smoothly and effectively, and a high deodorizing effect can be exhibited.

(Embodiment 3)
7 (a) and 7 (b) are a perspective view and a cross-sectional view of a main part of a dust bag for a vacuum cleaner according to a third embodiment of the present invention. Note that the same portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

The present embodiment is formed of an elastic material such as a ring and rubber, silicone, or a resin having elastic restoring force as shown in FIGS. 7A and 7B when the dust bag 1 is packed. The covering member 25 covers the discharge port 3d provided in the storage case 3. By doing so, the deodorizer 3a does not leak from the storage case 3 when the dust bag 1 is transported. There is no problem when using the dust bag.

  In addition, since the cover member 25 is formed of an elastic material and in a ring shape, it is easy to attach to and remove from the discharge port 3d, and the sealing performance of the discharge port 3d is improved. The deodorizing performance of the deodorizing agent 3a does not deteriorate when the dust bag 1 is stored.

  The covering member 25 may have any shape as long as it covers the outlet 3d (including the air inlet 3g when the air inlet 3g is provided), for example, a U-shape or the like. Various things are possible. Moreover, it is possible to prevent moisture from entering and solidifying by improving the sealing property of the covering member 25 covering the discharge port 3d (including the air inlet 3g when the air inlet 3g is provided). It can be maintained in a state that can be reliably supplied by maintaining it in a granular or powder form for a long period of time.

  In addition, by using the dust bag 1 described in the first to third embodiments for a vacuum cleaner, it exhibits excellent deodorizing performance over a long period of time, and always performs a comfortable and enjoyable cleaning operation. It is something that can be done.

  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 can be applied not only to a vacuum cleaner but also to various devices such as a garbage disposal machine that emits an odor.
