Abstract

<P>PROBLEM TO BE SOLVED: To provide a dust collection bag capable of effectively deodorizing the malodor generated from the dust for a long period of time. <P>SOLUTION: The dust collection bag comprises a mouth core 2 with an opening 2a for sucking dust to be attached inside a vacuum cleaner (not illustrated), a bag body 4 for capturing the dust sucked from the opening 2a of the mouth core 2, and a storage case 3 which communicates with the opening 2a and in which a granular or powder deodorant is stored. The dust collection bag is attached in such a way that the positions of the opening 2a of the mouth core 2, an opening of the storage case 3 and an intake 4a of the bag body 4 are superimposed on one another so that the opening 2a of the mouth core, the opening of the storage case 3 and the intake 4a of the bag body 4 communicate with each other. As the bottom of the storage case 3 is located lower than the bottom 2b of the mouth core 2 and the bottom 4a of the bag body 4, the deodorant remaining near the opening, even if falls downward, will not spill to the outside of the dust collection bag 1 after the operation of the vacuum cleaner is stopped. The deodorant is stored on the bottom of the storage case 3, and the deodorant stored on the bottom is immediately loaded into the bag body 4 with suction wind including dust for the next operation of the vacuum cleaner, so that the speedy deodorization effect can be obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

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

  Conventionally, as a method of deodorizing dust accumulated in a dust bag for an electric vacuum cleaner, a paper pack or a dust collection filter is impregnated with a deodorizing agent, and the deodorizing agent deodorizes the odor generated 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 the said patent document 2 disperses a deodorizing component in a dust collection chamber by installing a deodorizing fragrance | flavor in dust collection chamber space, and the dust in the dust collection bag for vacuum cleaners However, the deodorizing fragrance is mixed with the odor of the dust separately to reduce the exhaust odor. However, depending on the type of dust that has been sucked in, there is a problem in that it is 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 collection bag and a 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 a dust suction opening and a mouth core mounted in the vacuum cleaner. A bag-like body that collects dust sucked from the opening, a storage case that stores granular or powdery deodorant therein, and has a deodorant discharge port in a space that communicates with the opening of the wick. The bottom surface of the dust suction passage of the component located on the suction downstream side of the mouth core or the storage case is provided at a position lower than the bottom surface of the dust suction passage of the component upstream of the intake air. The dust or deodorant in the storage case is discharged from the storage case by the suction air during the suction of the dust, and is mixed with the sucked dust and accumulated in the bag-like body, so that the dust and deodorant are collected. The contact area of the agent is extremely wide, and the deodorizer is discarded and the dust bag is discarded or Since the bag remains until it is emptied, it has a great deodorizing effect and can last for a long time, so it can always be cleaned comfortably, and the deodorant that remains after the vacuum cleaner is stopped can be used as an intermediate. It can be temporarily stored in the bottom surface of the dust suction passage of the component parts and can be prevented from spilling, and can be put into the dust bag during the next operation to obtain a quick deodorizing effect.

  The dust bag of the present invention greatly reduces the exhaust odor from dust from vacuum cleaners and maintains the deodorizing effect for a long time until the dust in the dust bag reaches an allowable amount. be able to.

  The first invention has an opening for dust suction and a mouth core mounted in a vacuum cleaner, and a bag-like body for collecting dust sucked from the opening of the mouth core on the intake downstream side, A storage case having a granular or powdery deodorant therein and having a deodorant discharge port in a space communicating with the opening of the core; the suction downstream side of the core or the storage case Since the bottom surface of the dust suction passage of the component located on the side is provided at a position lower than the bottom surface of the dust suction passage of the component upstream of the intake air, the dust or dust in the storage case is generated by the suction air during dust suction. The deodorizing agent is discharged from the storage case and mixed with the sucked dust and deposited in the bag-like body, so that the contact area between the dust and the deodorizing agent is extremely wide, and the deodorizing agent is attached to the dust bag. Remains until it is discarded or the bag is emptied, Since the odor effect is large and can last for a long time, it is always possible to clean comfortably, and the deodorant that stays after the vacuum cleaner is stopped is temporarily stored and spilled on the bottom of the dust suction passage of intermediate components. Can be prevented and is put into the dust bag during the next operation, and a quick deodorizing effect can be obtained.

  In the second invention, in particular, the part located on the suction downstream side of the first invention is used as a storage case, and since a storage place for the deodorant can be secured immediately below the discharge port of the deodorant, the deodorant that stays is secured. Can be used efficiently in vacuum cleaners that use conventional dust collection bags that do not have a storage case. Bag manufacturing and inventory management are simplified.

  In the third invention, in particular, a bag-like body having a wall-like shape in which a part of the lower part of the opening of the first or second invention is made higher than the bottom surface of the component located on the suction downstream side is provided. In addition to storing the deodorant that stays more securely and preventing spillage more reliably, the wall-shaped part prevents the deodorant from being put into the dust bag when storing the main body upright. Thus, it is possible to secure more deodorizing agent until dust intrudes at the start of the next operation, and to obtain a quick deodorizing effect at the next operation.

  The fourth invention is particularly excellent in deodorizing because the bottom surface of the dust suction passage of the part located on the suction downstream side of any one of the first to third inventions is lowered from the intake upstream side to the downstream side. It is possible to provide a vacuum cleaner that exhibits its performance over a long period of time and can always be used comfortably.

  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.

  1-4, a dust collection bag (hereinafter referred to as “dust collection bag”) 1 for a vacuum cleaner has an opening 2a for dust suction, a mouthpiece 2 made of a paper material or a resin material, 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 attached to a vacuum cleaner) and that stores granular or powdery deodorant 3a, 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 attached to the back surface of the storage case 3 by bonding.

  The storage case 3 includes an opening 3b, and the inner peripheral surface 3c that forms the opening 3b and is parallel to the flow of the suction air flowing from the opening 2a of the wick 2 has an opening and an inside of the storage case 3. A plurality of outlets 3d are provided in communication with the portion 3b and through which the deodorant 3a stored therein is discharged. In addition, a soft substantially thin plate-like seal 3e is provided to block the opening 3b so that the deodorant 3a does not spill before use.

  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 connected to each other at the same position. At that time, the bottom 3 f of the storage case 3 is provided at a position lower than the bottom 2 b of the wick 2 and the bottom 4 a of the bag-like body 4.

  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 FIG.

  The electric vacuum cleaner main body (hereinafter referred to as “main 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 main body 6, and a connection pipe 11 a provided at one end of the hose 11 is connected to the intake port 10. A tip pipe 11b that is operated when the vacuum cleaner is used 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. 6, the main body 6 accommodates the dust bag 1 so as to be freely attachable and is covered with a dust cover 14 so as to be opened and closed. The electric blower chamber 17 that houses the electric blower 16 has an exhaust port (not shown) that communicates the electric blower chamber 17 with the outside and exhausts exhaust air from the electric blower 16 on the back. 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 portion of the main body 6.

  To attach the dust bag 1 to the main body 6, first, the lower end of the wick 2 of the dust bag 1 is inserted into the groove 22 provided in the bottom of the main body 6, and the upper end of the wick 2 is tilted to the cleaner body 6. It completes by hooking on the hook 23 provided freely. 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.

  First, by removing the seal 3e of the dust bag 1 attached to the main body 6, the discharge port 3d of the storage case 3 is opened, and preparation for discharging the deodorant 3a is completed. Next, when a plug (not shown) of a power cord (not shown) derived from the main body 6 is inserted into a wall outlet (not shown) and the switch 11c provided on the tip pipe 11b is operated, the operation of the electric blower 16 is performed. 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. .

  When the suction air containing dust passes through the opening 3b of the storage case 3, as shown in FIG. 1, 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 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.

  Further, among the deodorizers remaining in the storage case 3 after the operation of the cleaner is stopped, the deodorizer near the opening 3a may fall downward. In this case, the deodorizer falls to the bottom 3f of the storage case 3. Since the bottom 2b of the wick 2 on the intake upstream side is higher than the bottom 3f, the lip 20a of the packing 20 is pressed against the peripheral edge of the opening 2a of the wick 2 so that airtightness is maintained. Therefore, the deodorizer 3 a is stored in the bottom 3 f of the storage case 3 without spilling out of the dust bag 1. Then, during the next vacuum cleaner operation, suction force due to the ejector effect acts on the bottom portion 3f of the storage case 3 by the suction air containing dust, and the deodorant 3a stored in the bottom portion 3f is immediately put into the bag 4 The deodorizing effect can be obtained quickly.

  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.

  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 efficiently discharged 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.

  Furthermore, the bottom 4a of the bag-like body 4 fixed to the storage case 3 is provided higher than the bottom 3f of the storage case 3, so that the deodorizer 3a stored in the bottom 3f of the storage case 3 is stored even when the main body 6 is stood up and stored. Can be stored without deteriorating its deodorizing performance since it does not flow into the bag-like body 4 and is not mixed with dust until the next operation.

  Next, as shown in FIGS. 7 and 8, the bottom 3f of the storage case 3 is lowered from the intake upstream side to the downstream side, so that the deodorizer 3a stored in the bottom 3f of the storage case 3 after the operation of the cleaner is stopped can be further reduced. A large amount is stored on the downstream side to prevent the spilling out of the dust bag 1 more reliably, and even when the main body 6 is stood up and stored, the height difference with the bottom 4a of the bag-like body 4 becomes large, and a deodorizing agent. Since the storage space of 3a can be secured widely, the deodorant 3a stored in the bottom 3a of the storage case 3 does not flow into the bag-like body 4 and is not mixed with dust until the next operation. It can be stored without deteriorating.

  In addition, by using the dust bag 1 described in the present 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. .

  In the present 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, aldehydes and the like, which are odorous substances derived from dust, is used. 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 preferable in that it exhibits a high antibacterial effect 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.

  As described above, in the dust bag according to the present invention, the contact area and the contact time between the dust and the deodorizing agent are remarkably increased as compared with the conventional one, and as a result, the deodorizing effect is remarkably improved. The present invention can be applied not only to vacuum cleaners but also to various devices such as garbage processing machines that emit odors.
