More specifically, by improving the material of the dust-collecting unit to perform the dust collection in the cyclone method to carry out its own antibacterial / deodorizing function, antibacterial / to promote the health of the user and the comfort of using a vacuum cleaner Deodorizing function vacuum cleaner.

The vacuum cleaner is a device that collects the waste by filtering the dirt from inside the body by using the vacuum pressure formed by the vacuum motor installed inside the body, and then suctioning the air containing the foreign matter.

On the other hand, as a means for separating dust from the conventionally inhaled air, the dust filter is to be filtered while passing through the paper filter, and the cyclone method for separating the dust having a larger weight than the air from the sucked air by centrifugal force There is a vacuum cleaner. In recent years, the use of cyclone-type vacuum cleaners that can easily filter the discharge of filtered waste and permanently use the filter is increasing.

1 is a perspective view of a vacuum cleaner for filtering dirt by a conventional cyclone method.

Referring to FIG. 1, the vacuum cleaner includes a main body 10 having suction means for sucking air in the room, a suction hose 24 made of a flexible material connected to communicate with the inside of the main body 10, and the suction hose. Extension tube 22 is installed to communicate with the end of the 24 and the adjustable length 22, the suction nozzle 21 is introduced into the air containing foreign matter from the bottom surface by the suction force generated in the main body 10.

The main body 10 is provided with a dust collecting unit 11 detachable from the rear side. The dust collecting unit 11 is a part for performing a cyclone dust collection therein after introducing air containing foreign matter sucked from the suction nozzle 21. In addition, an exhaust unit 19 is formed at a side surface of the main body 10 to discharge air filtered with foreign substances from the inside of the dust collecting unit 11 to the outside.

At the bottom of the main body 10, a pair of wheels 18 for moving the main body are rotatably installed. In addition, on one side of the main body 10, a power cord 16 for supplying power to a vacuum cleaner is installed, the power cord 16 is stored inside while being wound on a cord reel (not shown) inside the main body It is installed to be possible.

In addition, the dust collecting unit 11 is formed with a handle 12 for the user to grip when detached from the rear of the main body 10. And the upper surface of the main body 10 is provided with a handle 14 that the user can hold when moving the vacuum cleaner.

When the vacuum cleaner main body 10 having the above configuration is driven, the suction force is transmitted to the suction nozzle 21 through the connection hose 24 and the extension pipe 22 by the suction force in the vacuum state formed therein. Here, the adjustment of the suction force of the vacuum cleaner is adjustable by the switch 25 installed in the handle portion 23 connected to the upper portion of the extension pipe 22.

And by the suction force, the air containing foreign matter on the bottom surface to be cleaned, the inlet nozzle 21, the extension pipe 22, and the suction hose 24 through the inside of the vacuum cleaner main body 10 do. In addition, the inside of the main body may be introduced into the dust collecting unit 11 and filtered by a predetermined filter, and then separately discarded to the outside.

Meanwhile, in the cyclone vacuum cleaner, the dust collecting unit is a place where dirt is accumulated until the dust is filtered and then discharged. Therefore, harmful bacteria, molds, etc., may grow inside the dust collecting unit and may damage the user's health.

Furthermore, when the vacuum cleaner is stored in a humid place or water is sucked through the suction port to maintain a high humidity state inside the dust collecting unit, bacteria and mold multiply exponentially, threatening the health of the cleaner user. . In addition, the inconvenience caused by the use of the vacuum cleaner is further encouraged by the odor generated during the growth of bacteria and fungi.

In particular, even if the dust accumulated inside the dust collecting unit is discarded, since the fine dust attached to the inner wall of the dust collecting unit by electrostatic attraction is not easily discharged, there is an inconvenience in that bacteria / fungus continue to multiply. . In order to remove such dirt there is an inconvenience that the user has to clean the dust collecting unit with water at regular intervals.

On the other hand, as a material to perform the antibacterial / deodorizing function in the natural state of the prior art has been introduced a number of materials related to the material containing silver (Ag) microparticles to perform the sterilization and deodorizing function. For example, Korean Patent Application No. 10-1999-0017059, "Antibacterial, anti-fungal solution and powder production method using silver compound", and Korean Patent Application No. 10-1998-0036411, "Antibacterial using group 1B compound and Deodorizing material ", Republic of Korea Patent Application No. 10-1997-0072878", "Sterile and anti-fungal agent produced by the combination of silver oxide and Group 7A element", and Republic of Korea Patent Application No. 10-1996-0036946, "Antibacterial water purifier and Metal ion water produced in this water purifier ”.

The technology introduced in this way suggests a method of further enhancing the sterilization and deodorization function of silver which has been introduced before.

The present invention has been made to improve the problems as described above, to propose an antimicrobial / deodorizing function vacuum cleaner that can suppress the growth of bacteria and fungi caused by dirt accumulated / adhered to the inside of the dust collecting unit The purpose.

In addition, an object of the present invention is to propose an antimicrobial / deodorizing function vacuum cleaner that can increase the user's health by suppressing the growth of bacteria and fungi attached to the inner wall of the dust collecting unit, and can use the cleaner in a more comfortable environment.

It is also an object of the present invention to propose an antibacterial / deodorizing vacuum cleaner which further enhances the convenience of use by preventing the growth of bacteria and fungi caused by dust on the inner wall of the dust collecting unit without cleaning the dust collecting unit. .

In particular, in the present invention, by using the plastic containing the nano-sized silver particles as a material forming the appearance of the vacuum cleaner, the antibacterial to suppress the growth of bacteria and mold by the dirt attached to the inner wall of the vacuum cleaner to which the dirt is attached It aims at suggesting a deodorizing function vacuum cleaner.

2, 3 and 4, the vacuum cleaner according to the present invention covers the upper end of the dust collecting unit to protect the internal parts and to prevent the intake air is not leaked, and the center of the cover approximately The filter 40 extends downward from the outlet 31 opened in the filter, and the dust collecting casing 80 formed below the cover 30.

In detail, an outlet 31 through which dirt is separated from the air sucked into the dust collecting casing 80 and clean air is discharged is formed at an approximately center portion of the cover 30, and a fine filter is disposed below the outlet 31. There is a filter 40 for implementing the structure to filter out the fine dust. The filter 40 has a circular columnar shape and a fine filter structure is formed on the outer circumference thereof, and after dust is filtered out from the air coming in from the outside, the filter 40 is discharged to the outside through the outlet 31.

In addition, the dust collecting casing 80 is an inflow path through which the air sucked into the vacuum cleaner main body is introduced into the dust collection unit, and the air sucked through the inflow port circulates, thereby causing the own weight of the dirt. And a circular dust separation chamber 70 for separating the dirt by centrifugal force, and a main dust collecting chamber 50 formed at the lower side of the dirt separation chamber 70 to accumulate dirt dropped by its own weight.

In addition, in order to horizontally partition the dirt separation chamber 70 and the main dust collecting chamber 50, a separator plate 73 integrally formed and fixed to the dust collecting casing 80, and an outer circumference of the separator plate 73 is opened. A lowering portion 74 is disposed so that the dirt hovered in the dirt separation chamber 70 falls into the main dust collecting chamber 50.

In addition, dirt may be generated that cannot fall through the lower portion 74 due to the light weight. In order to separate the light dirt, the upper communication hole 72 is opened in the upper side of the dirt separation chamber 70, and the auxiliary dust collecting chamber 60 which is another dust collecting chamber extending below the upper communication hole 72. ) Is included.

In addition, the boundary wall 75 for separating the main dust collecting chamber 50 and the auxiliary dust collecting chamber 60 into a wall, and the main dust collecting chamber 50 and the auxiliary dust collecting chamber 60 are mutually penetrating through the boundary wall 75. The lower communication hole 52 is further formed to be in communication to increase the efficiency of the waste collection.

In addition, a dust collecting chamber bottom surface 53 which opens and closes lower surfaces of the main dust collecting chamber 50 and the auxiliary dust collecting chamber 60, and a dust collecting chamber rotating center 81 in which the dust collecting chamber bottom surface 53 is opened and closed as a whole. Dust collecting chamber fixing means 54 is fixed to the dust collecting chamber bottom surface 53 so that its position is maintained.

In addition, the outer circumferential surface of the dust collecting casing 80 is formed long up and down to form a handle 12 for the user to grip. In addition, the stop plate 51 is formed to protrude inward from the outer circumferential surface of the main dust collecting chamber 50 and extend upward and downward to prevent dust from hovering inside the main dust collecting chamber 50.

In addition, the inlet 71 is formed in the tangential direction of the dirt separation chamber 70 so that the sucked air is circulated, so that the dirt is separated by the centrifugal force of the sucked air.

In addition, when the cover 30 is separated from the dust collecting unit 11, the cover 30 has a cover protrusion 32 as a handle structure for convenience of the operator.

In detail, an auxiliary dust collecting chamber 60 for collecting fine dust of the main dust collecting chamber 50 is formed in front of the main dust collecting chamber 50, that is, opposite the handle 12. The auxiliary dust collecting chamber 60 is formed between another boundary wall 75 which is one wall of the main dust collecting chamber 50. Fine dust continuously rotating along the upper part of the main dust collecting chamber 50 is collected in the auxiliary dust collecting chamber 60 via the upper communication hole 72. The main dust collecting chamber 50 and the auxiliary dust collecting chamber are separated by the boundary wall 75. (60) Reduce the effects of other air flows on each other.

However, an upper communication hole 72 and a lower communication hole 52 for communicating the main dust collecting chamber 50 and the auxiliary dust collecting chamber 60 with each other are formed in the boundary wall 75 of the main dust collecting chamber 50.

The upper communication hole 72 is formed to move the fine dust that continues to rotate the upper portion of the dirt separation chamber 70 to the auxiliary dust collecting chamber 60, the weight is small, free from the falling movement of the dust. . Since the upper communication hole 72 introduces the dust hovering along the upper wall of the waste separation chamber 70 into the auxiliary dust collecting chamber 60, it is preferable to form the upper portion of the boundary wall 75.

In addition, the lower communication hole 52 is formed in the lower portion of the boundary wall 75, so that the dirt accumulated in the main dust collecting chamber 50 is also accommodated in the interior of the auxiliary dust collecting chamber 60.

In detail, large dust is mainly collected in the main dust collecting chamber 50 of the dust collecting casing 80, and fine dust is collected in the auxiliary dust collecting chamber 60, so even if the main dust collecting chamber 50 is full of dust, the auxiliary dust collecting chamber 60 happens to be empty yet. In this case, when the dust is overflowed in the main dust collecting chamber 50, in order to move a part of the dust to the auxiliary dust collecting chamber 60, the lower communication hole 52 is formed.

As such, when the main dust collecting chamber 50 is filled with dust, the dust of the main dust collecting chamber may naturally move to the auxiliary dust collecting chamber 60 through the lower communication hole 52, thereby more effectively collecting the dust collecting space of the dust collecting casing 80. Can be used as

And by forming the lower communication hole 52, part of the air introduced from the inlet 72 flows through the lower communication hole 52 from the upper communication hole 72 to the interior of the main dust collecting chamber 50, the flow path is cut off This can be continued without losing the suction force. If the lower communication hole 52 is not formed, the air passing through the upper communication hole 72 has a vortex formed inside the auxiliary dust collecting chamber 60, so that the air flow is not made as much as the formed vortex, and thus a loss of suction force occurs.

At the lower part of the said outlet 31, the cylindrical filter 40 is provided. The filter 40 is detachably attached to the lower surface of the cover 30 such that the cylindrical interior communicates with the outlet 31. The dirt-filtered air is purified into cleaner air through the filter 40 and is discharged to the outside of the main body.

In the dust collecting unit which is the object of the present invention as described above, as the member in which the collected dirt directly comes into contact, a cover 30, a filter 40, and a dust collecting casing 80 formed below the cover 30 are provided. There is this.

In detail, the filter 40 includes a filter housing made of resin, and a dust collecting filter formed on an inner surface or an outer surface of the filter housing and having a plurality of predetermined fine holes. The dust collecting casing 80 includes an inlet 71, a dirt separation chamber 70, a main dust collecting chamber 50, a separation plate 73, an auxiliary dust collecting chamber 60, and a boundary wall 75. The resin can be formed integrally with its material, and can be formed by the method of injection. In addition, the bottom surface of the dust collecting casing 80 is formed with a dust collecting chamber bottom surface 53 through which dirt can be discharged.

The filter 40, the dust collecting casing 80, and the dust collecting chamber bottom surface 53 are directly in contact with dirt. Therefore, the growth of bacteria and mold occurs due to the attached dirt, and in particular, since the dirt attached to the inner surface of each member does not fall off and sticks for a long time, there is a risk of providing an environment suitable for breeding bacteria.

The present invention is characterized by the use of a plastic containing silver as the material of each article constituting the dust collecting unit. That is, by using a predetermined sterilizing material containing sound in the resin as a material, it is possible to suppress the growth of bacteria and fungi adhered to the surface of the resin. As described, the resin contains silver so that the resin material having a predetermined sterilization / deodorization function is named as nano-poly. This is because the silver particles contained in the resin are nano-size fine particles, which are sufficiently dispersed in the resin to promote sterilization / deodorization.

In detail, the filter housing, the dust collecting casing 80, and the dust collecting chamber bottom surface 53 which are a part of the filter 40 are made of plastic, and the material further includes silver particles. Part of the dust collecting casing 80, in particular, the silver particles should be contained in the inlet port (71), which is directly in contact with the dirt, the dirt separation chamber 70, the main dust collecting chamber 50, the separation plate 73, The auxiliary dust collecting chamber 60 and the boundary wall 75 are provided, and at least these portions may be made of plastic containing sound. However, when the inlet 71, the dirt separation chamber 70, the main dust collecting chamber 50, the separating plate 73, the auxiliary dust collecting chamber 60, and the boundary wall 75 are integrally formed, Because it can be formed by one injection, it will not be very inconvenient.

The nanopoly will be described in more detail. The nanopoly is a resin composition containing silver particles up to nano size, and has its own antimicrobial, antistatic, conductive, harmless, antibacterial, deodorant, etc. to the human body through a number of documents, In addition, unlike antibiotics there is an advantage that does not cause resistance. Since the sterilization mechanism produced by silver (Ag) is already well known, a detailed description thereof will be omitted.

In addition, the silver (Ag) constituting the main component of the nanopoly is mixed with the resin in the range of 0.1 to 50% by weight as a weight ratio, the size may range from 1 nanometer to several tens of nanometers. In addition, the sterilizer / deodorant containing silver in nanometer units may be produced by a technique that has been proposed in the prior art. In addition, the method of mixing the silver particles in nanometer units with the resin may be prepared by a process of applying silver (Ag) particles to the resin composition by a method such as emulsion polymerization, dispersion polymerization, microemulsion polymerization. In addition, as the material of the resin, a plurality of resin materials which can be exemplified by vinyl chloride, styrene, butadiene, acrylonitrile, but not limited thereto, may be used.

On the other hand, the nanopoly can be used after mixing the entire material in a predetermined ratio with the resin for the sterilization / deodorization, in detail, the ratio of the general resin to the nanopoly used in the vacuum cleaner is 1: 9 It can be used in the ratio of -2: 8, and predetermined sterilization / deodorization effect can also be acquired by resin mixed in this way.

In addition, by adding a suitable dye or pigment in the process of mixing the nanopoly and ordinary resin, it is also possible to achieve the desired color.

The results of the antimicrobial test on the mixed resin of nanopoly and general resin are presented. The experimental method shows the result of experimenting the common resin and the nanopoly mixed resin through the same process. In detail, the plastic to be tested is cut to a predetermined size (25 cm 3), and various strains are administered at predetermined concentrations on the surface of the cut plastic, and the coated film (STOMACHER After covering 400 POLY-BAG), the strain concentration was measured after the static culture in a constant environment (35 土 1 ℃, RH 90%, 24 hours).

Table 1

In Table 1, Strain 1 is Staphylococcus aureus, Strain 2 is Klebsiella pneumoniae, Strain 3 is Escherichia coli, and Strain 4 is Pneuudomonas aeruginosa.

Referring to Table 1, after performing the experiment in the proposed experimental environment, compared to the general resin, it can be seen that the killing of the bacteria up to 99.8% of the nanopoly mixed resin. Such killing of bacteria can be expected to have the same effect on molds and the like, and the effect of deodorization by killing of bacteria and molds can also be obtained.

As such, the bacteria introduced into the surface of the nanopoly mixed resin are almost completely killed by the nano-sized silver particles.

As the nano-poly resin is used in a cleaner, the bacteria collected together with the dirt inside the cleaner are killed by the same action, thereby improving the user's health and driving the cleaner in a more comfortable environment.

As described above, among the plurality of components constituting the dust collecting unit, a place where the nano-poly mixed resin is used is a portion in which dirt collected directly from the outside comes into direct contact with the dust collecting casing 80, the filter 40, and the cover. It is preferable to use for (30).

In detail, the inlet 71, the dirt separation chamber 70, the main dust collecting chamber 50, the separating plate 73, the auxiliary dust collecting chamber 60, among a plurality of configurations constituting the dust collecting casing 80, At least one portion of the boundary wall 75 may be formed of a nanopoly mixed resin. In addition, the filter housing forming the exterior of the filter 40 may also be formed of a nanopoly mixed resin.

According to the present invention, it is possible to suppress the proliferation of bacteria and fungi caused by dirt accumulated / attached inside the dust collecting unit.

In addition, by suppressing the growth of bacteria and fungi adhered to the inner wall of the dust collecting unit can promote the health of the user, and provide a more comfortable environment.

In addition, even if the dust collecting unit is not cleaned, it is possible to further suppress the growth of bacteria and mold caused by the dust adhering to the inner wall of the dust collecting unit, thereby further improving convenience in use.
