The present invention relates to a vacuum cleaner, and in detail, by reducing the volume of foreign matter collected in the dust collecting unit of the vacuum cleaner, so that the efficiency of collecting the foreign matter is increased, the service life of the vacuum cleaner is long, and the visual image is improved. It relates to a vacuum cleaner to improve the aesthetics of the user.

A vacuum cleaner is a home appliance that cleans an indoor environment by external air being forcibly sucked by a suction force generated by a fan and a motor, and foreign matter contained in the sucked air is filtered by a predetermined filtering member.

On the other hand, the filtering mechanism for filtering foreign matter in the dust collecting unit of the vacuum cleaner includes a porous filter unit forcibly filtering foreign matter while passing through the porous filter, and a cyclone for filtering foreign matter by centrifugal force during the cyclone flow of air. There is a dust collecting unit of the type. In recent years, a cyclone dust collecting unit that can be used semi-permanently without replacement is widely used.

In addition, the cyclone dust collecting unit is provided with a foreign matter separation chamber in which a cyclone air flow is formed to separate foreign matter, and a foreign matter storage chamber in which foreign matter separated from the foreign matter separation chamber is stored. The foreign matter separated from the foreign matter separation chamber by this structure is continuously accumulated in the foreign matter storage chamber, and the foreign matter is stored above a certain volume and discarded to the outside by the user when the efficiency of cleaning decreases. In addition, the foreign matter collected in the foreign matter storage chamber, if not discarded in a proper time, there is a problem that the dust collection efficiency of the cleaner is lowered, and the appearance is not good even if it is not discarded in a proper time.

However, the foreign matter collected in the foreign matter storage chamber in the cyclone dust collecting unit has a problem of low stacking density because foreign matters separated from the foreign matter separation chamber are accumulated in the process of free fall by self weight. In other words, since the volume of the foreign matter is substantially large while the amount of the foreign matter accumulated inside the foreign matter storage chamber is excessively large, there is a disadvantage in use that the user frequently has to empty the foreign matter storage chamber. Furthermore, even if foreign matters of low density are collected excessively, if foreign matters are not discarded at an appropriate time interval, foreign matters may accumulate to the foreign matter separating chamber, impeding the flow of air and deteriorating the efficiency of foreign matter separation, and external appearance may also be good. There is no disadvantage.

This problem is more apparent when the foreign matter collected inside the foreign matter storage chamber is fine dust and has a low size and density but occupies a large volume.

In addition, even when the foreign matter disposal operation, there is a disadvantage that the user has to wash the foreign matter storage chamber separately, because fine foreign matter does not fall to the inner wall of the foreign matter storage chamber, and the collected fine foreign matter is excreted and discharged back into the room again. There is a problem of contamination again.

The present invention has been proposed to improve the above problems, and an object of the present invention is to propose a vacuum cleaner in which the size of the foreign matter collected in the foreign matter storage chamber is increased and the density of the foreign matter is increased so that the efficiency of foreign matter separation is improved. .

In addition, by increasing the size of the separated foreign matter to increase the amount of foreign matter that can be collected inside the same volume of foreign matter storage chamber, the frequency of discarding the foreign material is reduced by the user can use the vacuum cleaner more conveniently It aims to propose a cleaner.

In addition, an object of the present invention is to propose a vacuum cleaner capable of preventing the volume of foreign matters from swelling inside the foreign matter storage chamber, thereby improving the visual aesthetics of the user.

In addition, it is an object of the present invention to propose a vacuum cleaner in which the foreign matter forms a mass inside the dust collecting unit, which facilitates the disposal operation of the foreign matter and prevents the collected foreign matter from being discharged again to the outside, thereby improving convenience in use. .

Vacuum cleaner according to the present invention for achieving the above object is a vacuum cleaner body; A dust collecting unit selectively housed in the vacuum cleaner body to collect foreign matter; A foreign material storage chamber formed on one side of the dust collecting unit and storing the collected foreign matter; A chamber sealing unit selectively opening the foreign matter storage chamber; A thermoelectric module provided in the vacuum cleaner body and supplying cold air to the foreign matter storage chamber through the chamber sealing unit, to generate water droplets on an inner wall of the foreign matter storage chamber; And a cooling plate configured to transfer the cool air of the thermoelectric module to the chamber sealing unit, and when the dust collecting unit is mounted to the vacuum cleaner body, the cooling plate contacts the chamber sealing unit, and when the vacuum cleaner body is operated. A portion of the thermoelectric module in contact with the cooling plate may serve as a cooling surface.

According to the present invention, the dust collecting efficiency of the vacuum cleaner is improved, the period in which the user has to discard the foreign material is long, and the aesthetics of the dust collecting unit can be improved. In addition, since foreign matter is agglomerated in the dust collecting unit, the filtered foreign matter is discharged again to the outside, which has the advantage of improving the problem of the indoor environment.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First Embodiment

1 is a perspective view of a vacuum cleaner according to the spirit of the present invention.

Referring to FIG. 1, the vacuum cleaner of the present invention includes a vacuum cleaner body 100 and a suction pipe path connected to the suction side of the vacuum cleaner body 100. At least a suction fan and a dust collecting unit are disposed inside the vacuum cleaner main body 100, and foreign substances are caught and cleaned in the sucked air and then discharged to the outside.

The suction pipe is a pipe in which foreign matter is sucked together with air by the suction force of the vacuum cleaner main body 100. In detail, the suction pipe passage includes a suction nozzle body 1 for sucking foreign matter and dust together with air from the outside by a strong air flow, and a length extending from the suction nozzle body 1 according to a user's use state. A stretchable extension tube 2, an operation handle 3 provided at an end of the extension tube 2, and an operation unit 4 provided at a portion where the user's hand touches the front of the operation handle 3; And a flexible tube 5 further extending rearward from the operation handle 3 and bent according to the position of the user, and a connector 6 connected to the vacuum cleaner body 100 at an end of the flexible tube 5. And an extension tube hook 7 for placing the extension tube 2 in a predetermined position of the extension tube 2 or the suction nozzle body 1 when the vacuum cleaner is not used.

The connector 6 has a function of a connection terminal for allowing the user's operation signal input from the operation unit 4 to be applied to the vacuum cleaner body 100, and to allow the sucked air to flow into the vacuum cleaner body 6. The function is performed at the same time. To this end, a plurality of electrical connection ends are further provided at the ends of the connector 6. On the other hand, the connector 6 is necessary only when the operation unit 4 is placed in any part of the suction pipe, the present invention is not limited thereto. That is, when the operation unit 4 is formed anywhere in the vacuum cleaner body 100, the connector 6 may allow only the function as the inflow passage of air without the signal connection end.

In addition, the air introduced into the vacuum cleaner main body 100 through the suction pipe passage is discharged to the outside of the vacuum cleaner main body 100 after the foreign matter is filtered and cleaned inside the vacuum cleaner main body 100. Hereinafter, the configuration of the vacuum cleaner body 100 will be described.

2 is a front perspective view of the vacuum cleaner body.

Referring to FIGS. 1 and 2, the structure of the vacuum cleaner body will be described. In the vacuum cleaner body 100, a first base 110 provided on the bottom surface of the body 100 and the first base ( The second base 150 placed on the upper right side of the 110, the wheels 111 provided on both sides of the rear portion of the main body 100 to smoothly move the vacuum cleaner main body 100, and the vacuum cleaner A cover 200 provided at an upper portion of the main body 100 and a front supporter which is firmly supported between the cover 200 and the base 110 and 150 at a front portion of the main body 100 ( 170).

Of course, the connector 6 is connected to the front supporter 170 to allow outside air to be sucked. In addition, the front supporter 170 allows the shape of the front part of the vacuum cleaner body 100 to be firmly supported.

The second base 150 is provided directly above the first base 110 so that the shape of the product is beautifully maintained and the strength of the lower side of the vacuum cleaner body 100 is increased.

An exhaust cover 301 is provided at the rear of the cover 200 to form a main body exhaust port 302 so that the air cleaned by the vacuum cleaner body 100 is discharged. In addition, a movable handle 201 is formed on the upper surface of the cover 200 to rotate around a predetermined hinge point. The movement handle 201 is moved by the user's operation, so that the vacuum cleaner main body 100 is upright when the user wants to move it, and when it is stored, the mobile handle 201 can be conveniently used.

At the rear of the front supporter 170, a dust collecting unit 400 is seated so that outside air flows in, and a cyclone member is accommodated in the dust collecting unit 400 to filter foreign matter by cyclone flow.

As shown in FIG. 3, the dust collecting unit 400 is seated in a vertical direction on the dust collecting unit accommodating part 151 inside the vacuum cleaner body 100. Therefore, it is necessary to push downward when mounting and pull upward when removing.

The front supporter 170 is provided with a main body suction port 171, and a dust collecting unit suction port 401 is positioned at a corresponding position on the dust collecting unit 400 aligned with the main body suction port 171. In addition, a discharge port is formed in the dust collecting unit 400 in a direction opposite to the dust collecting unit suction port 401. In addition, the discharge port is aligned with the motor side suction port 172 and passes through the dust collecting unit 400 and the clean air is sucked to the motor side.

The discharge port and the motor side suction port 172 are provided in a flat rectangular shape in order to reduce the size of the vacuum cleaner body 100 and allow the air to flow smoothly.

On the other hand, the cooling plate 601 is formed on the upper surface of the second base 150 that the lower surface of the dust collecting unit 400 is to supply cold air to the dust collecting unit 400, to form the dust collecting unit 400 Dew is generated on the wall, particularly the inner wall, by cold air supplied from the cooling plate 601. In addition, dew, which is formed in the dust collecting unit 400, that is, water droplets, is formed so that the size of the fine foreign matter is increased by performing an operation for the fine foreign matter to be agglomerated. In other words, water droplets having high adhesion are provided in the space where foreign matter flows inside the dust collecting unit 400, and the foreign matter is coarse in a state in which the foreign matter is agglomerated even after the water droplets evaporate. As a result, the fine foreign matter is maintained at a high density.

In this case, when the water droplets adhere to the inner wall of the dust collecting unit 400, after the water droplets have evaporated, coarse foreign materials attached to the inner wall of the dust collecting unit fall off and accumulate in the inner space of the foreign matter storage chamber. It will of course be predictable that the density of foreign matter trapped inside the 400 is increased.

On the other hand, the lower surface of the cooling plate 601 is provided with a thermoelectric module (see 610 of FIG. 7), to provide cold air to the cooling plate 601. The thermoelectric module 610 is a device for moving heat by using electricity as an energy source using the Peltier effect. The surface facing the cooling plate 601 becomes a cooling surface and the opposite surface of the cooling surface is a heat radiating surface. It works.

When the operation of the thermoelectric module 610 is described in more detail, when a semiconductor having different electrical conduction methods such as bismuth (Bi) and teltur (Te) is alternately formed and energized, electricity is generated on one side and the opposite is caused. The surface acts in such a manner that the endothermic phenomenon takes place, so that the surface where the endothermic phenomenon occurs becomes the cooling surface, and the cooling plate 601 is cooled. The kind of the semiconductor is not limited to the material to be introduced, and other thermoelectric modules of various types may be used. However, it is natural that the endothermic phenomenon is performed on the surface opposite to the cooling plate 601 by the power applied from the outside.

Referring to FIG. 4, the second base 150 is placed in front of the upper portion of the first base 110, and the motor housing 300 is placed in the rear thereof. Then, the cover 200 is sequentially covered to form the main body 100 of the vacuum cleaner.

Here, the cover 200 is coupled to the base 110 and 150 in a state where the front supporter 170 is fastened to the cover 200 as a separate part. In the motor housing 300, the air sucked through the motor side inlet 172 flows downward in a vertical direction. Then, the introduced air is discharged to the rear by bending the flow direction in the motor housing 300 horizontally.

Meanwhile, a portion of the first base 110 corresponding to the surface on which the heat generation occurs in the thermoelectric module 610 forms a heat dissipation part 602, which is opened through the heat dissipation part 602. The heat generated from the heat dissipation surface of 610 is radiated to the outside so that there is no problem.

5 is an exploded perspective view of the dust collecting unit according to the present invention.

Referring to FIG. 5, the dust collecting unit 400 of the present invention does not use a porous filter such as a sponge or the like, and filters foreign matter from the cyclone flow.

The cover insertion slot 411 covers a part of the upper surface portion of the first cover 410 so that the appearance is beautifully implemented, and the first cover 410 and the second cover 409 are simultaneously fixed.

Inside the dust collection body 406, a conical filter 405 for smoothly separating the dirt in the cyclone flow, and a blocking portion for preventing the re-scattering of foreign matter collected under the conical filter 405 ( 404, a flow preventing plate 403 is formed below the blocking portion 404 to slow the flow rate of the air to be rotated, so that the foreign matter sinks inside the dirt storage chamber. Here, the blocking part 404 and the flow preventing plate 403 may be formed in one body, and the conical filter 405 may be formed as a separate component.

In addition, an opening and closing button 413 is placed at one side of the first cover 410, and one end of the opening and closing button 413 is in contact with the opening and closing operation is performed by the push operation of the opening and closing button 413 Lever 414 is included. In addition, the other end of the opening / closing lever 414 contacts the first chamber sealing part 415. Therefore, by the pressing operation of the opening and closing button 413, the opening and closing lever 414 is rotated about a predetermined hinge point. When the contact portion between the first chamber sealing portion 415 and the opening / closing lever 414 is separated from the other end of the opening / closing lever 414, the first chamber sealing portion 415 may set a hinge point by its own weight. The foreign material that is rotated about the center and collected in the foreign matter storage chambers 416 and 417 is dropped by its own weight and discarded.

In addition, the chamber sealing parts 415 and 402 allow each of the lower surfaces of the foreign material storage chambers 416 and 417 to be hermetically sealed by the respective sealing parts. In addition, the first chamber sealing part 415 is hinged to the dust collecting body 406, and when discarding the foreign material, the first chamber sealing part 415 is opened by the hinge movement so that the foreign material can be easily discarded. . In addition, a separation plate 437 is formed on the upper surface of the dust collecting body 406 to partition the first foreign matter separating chamber 423 and the second foreign matter separating chamber 424 and form a flow path.

In addition, the outer surface of the dust collecting body 406 when the exhaust portion 407 is seated to the outside of the dust collecting body 406 is easily located, a plurality of guide ribs (so that the insertion operation is performed smoothly) 459 is formed. In addition, the upper edge portion of the guide rib 459 is smoothly curved, so that the insertion operation of the exhaust part 407 is easily performed. In addition, since the inner surface of the exhaust portion 407 is in contact with the outer surface of the guide rib 459, even if an external impact is applied to the exhaust portion 407, the guide rib 459 Since the shock is absorbed and the shock is supported, breakage of the body of the exhaust portion 407 can be prevented.

FIG. 6 is a cross-sectional view taken along line II ′ of FIG. 3, and with reference to FIG. 6, the internal structure of the dust collecting unit 400 and the operation of the dust collecting unit will be described in detail.

First, as described in detail with reference to FIG. 5, in the dust collecting unit 400 according to the present invention, a dust collecting body 406 and a sealing part 402 for selectively sealing the lower side of the dust collecting body 406 ( 415, the conical filter 405 accommodated inside the dust collecting body 406 to increase dust collection efficiency, the blocking portion 404 for preventing re-splash of the collected foreign matter, and the flow rate of cyclone flow is reduced. A flow preventing plate 403 to allow foreign matters to fall, and an exhaust part 407 placed above the dust collecting body 406 to allow the air discharged from the dust collecting body 406 to flow smoothly. And a gap 408 for collecting the air passing through the exhaust 407 in one direction, and covers 409, 410, 411 and 412 that are placed above the exhaust 407. do.

The configuration of the dust collecting body 406 will be described.

The dust collecting body 406 is provided with a plurality of walls extending up and down, the outer wall 418 formed on the outermost, the intermediate wall 419 formed inside the outer wall 418, and the intermediate wall ( An inner wall 420 formed inside 419 is included. The intermediate wall 419 and the inner wall 420 are not formed at intervals through which the dust collecting unit side suction port 401 passes, thereby allowing air to flow smoothly.

The space between the outer wall 418 and the intermediate wall 419 is the first foreign matter storage chamber 416, and the space between the intermediate wall 419 and the inner wall 420 is the second foreign matter storage chamber 417. The inner space of the inner wall 420 becomes the first foreign matter separation chamber 423. However, according to the shape of the dust collecting unit 400 in detail, the purpose of using the space may vary.

The operation or operation by the above-described configuration will be described in detail based on the flow order of air. First, the dust is introduced into the dust collecting unit 400 through the dust collecting unit side suction port 401. Here, the dust collecting unit side suction port 401 is in contact with the front supporter 170 on the outside, and communicates with the first foreign matter separation chamber 423 on the inside to introduce the outside air. In addition, a first inflow guide 421 is inward from the inner wall 420 so as to guide the flow direction of air in the direction of the inner circumferential surface of the first foreign matter separation chamber 423 inside the dust collecting unit side suction port 401. Protrudes.

During the cyclone flow of air in the first foreign matter separation chamber 423, the foreign matter falls downward and clean air passes through the opening of the conical filter 405 and is discharged upward.

The conical filter 405 is seated at the center of the separation plate 437 forming the upper wall of the first foreign matter separation chamber 423, it may be provided in a structure that can be selectively separated from the separation plate (437). In addition, the conical filter 405 is formed with a plurality of openings, of course, the air flows in from the outside into the inside.

Here, the blocking portion 404 is placed under the conical filter 405 in order to prevent the re-splash of the falling foreign matter, as shown, the blocking portion 404 is expanded in diameter downwards, the foreign matter The rise of is blocked and do not get excited. In addition, a flow preventing plate 403 is formed below the blocking portion 404 at regular intervals, so that the cyclone air flow is not reached for the foreign matters once collected, so that the phenomenon of foreign matters is eliminated. do.

On the other hand, water droplets form inside the first foreign matter storage chamber 416 due to the cold air supplied from the cooling plate 601, and fine particles are coarsened by the water droplets. Can be. In addition, as the fine foreign matter is coarsened, the possibility of the fine foreign matter being discharged to the outside again decreases, and even if water droplets evaporate, the foreign matter remains coarse, so the volume of the fine foreign matter decreases, and thus the cycle of discarding the fine foreign matter is reduced. It becomes long, and since the flow resistance of the air by the fine foreign material itself is reduced, it is possible to obtain the advantage that the reduction of dust collection efficiency is prevented.

In addition, the foreign material filtered in the first foreign matter separation chamber 423 is stored in the first foreign matter storage chamber 416 below. Here, the first chamber sealing part 415 is placed at the lower end of the first foreign matter storage chamber 416 to prevent leakage of the stored foreign material. Below the first chamber sealing part 415, the cold cold air generated by the cooling plate 601 is supplied to the first chamber sealing part 415. Furthermore, in order to allow the cool air of the cooling plate 601 to be smoothly transferred to the first foreign matter storage chamber 416 through the first chamber sealing part 415, the first chamber sealing part 415 is made of aluminum. A metal of high thermal conductivity may be used.

On the other hand, the air flowing through the conical filter 405 to the upper side of the separation plate 437 is largely filtered foreign matter. Therefore, there is a further need for cyclone flow to allow secondary fines to be filtered out. Hereinafter, the cyclone flow performed further will be described in detail.

Air passing through the conical filter 405 is introduced into the plurality of second foreign matter separation chamber 424 through the second inlet guide 422. In addition, since the second inflow guide 422 directs the inner circumferential surface of the second foreign matter separation chamber 424 in a tangential direction, air introduced into the second foreign matter separation chamber 424 may be formed in the chamber. Cyclone flow occurs.

The foreign matter separated by the cyclone flow in the second foreign matter separation chamber 424 is dropped downward and stored in the second foreign matter storage chamber 417. In order to prevent the dropped foreign material from scattering again, the lower portion of the second foreign matter separating chamber 424 is contracted. In addition, the lower portion of the second foreign matter storage chamber 417 is sealed by the second chamber sealing part 402 in order to prevent the foreign matter collected in the second foreign matter storage chamber 417 from leaking.

After the foreign material is filtered in the second foreign matter separation chamber 424, the foreign material is introduced into the exhaust part 407 via the exhaust part side suction port 425, and the gap between the exhaust part 407 and the spacer part 408 is provided. Gather in space. Here, the diameter of the exhaust side suction port 425 is smaller than the inner diameter of the second foreign matter separation chamber 424, the foreign matter of the second foreign matter separation chamber 424 is the exhaust portion ( The possibility of flowing together with 407 can be further reduced. In other words, the foreign matter gathered on the inner circumferential surface of the second foreign matter separation chamber 424 is prevented from flowing out through the exhaust side suction port 425.

As described, air filtered by foreign matter by two cyclone flows flows into the motor side inlet 172 and flows into the motor. Then, after passing through the motor is exhausted to the rear of the vacuum cleaner body (100).

In addition, a predetermined cover structure is further formed on the upper portion of the spacer 408. In detail, the first cover 410 forming the overall cover structure, the third cover 412 and the second cover 409 protecting the front and the rear of the first cover 410, and the first cover A cover insertion hole 411 is provided at 410 to fix the second cover 409.

Meanwhile, the second foreign matter storage chamber 417 has a function of storing as much foreign matter separated from the first foreign matter separation chamber 424 as possible, and the foreign matter stored in the first foreign matter storage chamber 416 is caught and moved. Function to ensure that the data is stored correctly. This function and each configuration of the second foreign matter storage chamber 417 will be described in detail.

7 is a perspective view illustrating the structure of the second foreign matter storage chamber in the dust collecting unit according to the present invention.

Referring to FIG. 7, the second foreign matter storage chamber 417 is provided extending downward of the dust collecting body 406.

In detail, the upper end of the second foreign matter storage chamber 417 is formed in an arc shape along the position where the second foreign matter separation chamber 424 is disposed and extends downward. Then, at four locations extending downward, a primary storage unit 446 is formed in which the foreign matter separated from the second foreign matter separation chamber 424 is first stored. Preferably, at least two primary storage units 446 are formed in order to secure a wide space for receiving a foreign material, and to allow the water rotated in the first foreign material storage chamber 416 to be caught.

In addition, the first inclined surface 440 is formed to be inclined at a predetermined angle so that the foreign matter separated from the second foreign matter separation chamber 424 is smoothly dropped to be collected into the primary storage unit 446. The first inclined surface 440 is provided in a state where there is no horizontal portion in a relatively wide area so that foreign matters separated from all the second foreign matter separation chambers 424 are guided to the primary storage part 446 side. In addition, a second inclined surface 442 having a steeper inclination angle than that of the first inclined surface 440 is formed at a portion further extending downward from the first inclined surface 440. Of course, the inner space of the second inclined surface 442 forms a primary storage unit 446 in which foreign materials are collected, even inside the second foreign matter storage chamber 417.

In addition, the primary storage unit 446 is shown as being formed at equal intervals in the place, but is not limited to this, more than that may be formed.

On the other hand, the second inclined surface 442 not only serves as the primary storage unit 446 in which foreign matter is collected in the inner space, but also the outer wall is shaken because the foreign matter trapped in the first foreign matter storage chamber 416 is caught. It serves as a locking portion that does not. In addition, since the primary storage unit 446 is provided in a relatively large area in the shape of a circular frame, even if a long foreign material such as a hair is caught, the user can be quickly removed by a pulling force downward. Of course, since the second inclined surface 442 has a predetermined inclination angle, the user can smoothly remove the foreign material by pulling the foreign material downward.

In addition, since the lower end portion of the second inclined surface 442 is in contact with the inner surface of the second chamber sealing portion 402, foreign matter collected in the primary storage portion 446 is transferred to the first foreign matter storage chamber 416. Not only does not escape, there is an advantage that does not occur between the air flow.

The overall operation to the operation of the vacuum cleaner main body 100 together with the above-described operation of the dust collecting unit 400 will be described in detail with reference to the cross-sectional view of II-II 'of FIG. 2 as the longitudinal cross-sectional view of the vacuum cleaner shown in FIG. .

Referring to FIG. 8, first, the operation of the vacuum cleaner of the present disclosure will be described based on the inflow and outflow paths of foreign objects, and the outside air may be transferred to the vacuum cleaner body 100 through the main body side suction port 171 connected to the connector 6. It is introduced, and is introduced into the dust collecting unit 400 through the dust collecting unit side suction port (401). In addition, after the foreign matter is filtered by the operation and action as described above, the dust collecting unit 400 is introduced into the motor housing 300 through the motor side suction port 172.

At this time, the inlet is directed upward in the state in which the motor housing 300 is erected in the vertical direction. Therefore, the air introduced horizontally through the dust collecting unit 400 is turned downward to be directed downward. Then, after passing through the motor housing 300, it is discharged to the outside through the main body exhaust port 302 provided on the back of the vacuum cleaner body 100.

Referring to the coarsening process of the foreign material, when the power is applied to the thermoelectric module 610, the endothermic phenomenon occurs on the first surface of the thermoelectric module 610 facing the cooling plate 601, the cooling Allow plate 601 to cool. The second surface opposite to the first surface generates heat and heat is discharged to the outside through the heat dissipation unit 602.

In addition, the cold air delivered to the cooling plate 601 is transferred to the first foreign matter storage chamber 416 through the first chamber sealing unit 415, so that water droplets are formed on the inner wall surface of the first foreign matter storage chamber 416. To be generated. In addition, since foreign matters are attached to the water droplets, the foreign matters are coarsened around the water droplets. In addition, when the amount of cold air is controlled by adjusting the action of the thermoelectric module 610, the size and amount of water droplets may be easily controlled.

The foreign matter introduced into the first foreign matter storage chamber 416 is attached by the adhesion force of the water droplets, and the adhesion amount of the foreign matter continues to increase so that the coarsening of the foreign matter proceeds further.

The generation and delivery of such cold air continues to occur during the operation of the vacuum cleaner, so that the coarsening of the foreign material continues. Thereafter, after the operation of the vacuum cleaner is finished, the direction of the current applied to the thermoelectric module 610 is reversed so that the cooling plate 601 is operated as a heating plate to promote the evaporation of the water droplets, thereby focusing on the water droplets. As a result, the coarse foreign matter remains in a lump to be collected in the first foreign matter storage chamber 416. Of course, when the operation of the thermoelectric module 610 is not reversed, water droplets may be naturally evaporated by heat transmitted from the outside.

As a result, foreign matter inside the first foreign matter storage chamber 416 is collected in a coarse state and its density is enhanced, thereby occupying a small volume in a high density state within the foreign matter storage chamber. Therefore, because the volume of foreign matter is small, foreign matter is not lifted from the inside, so that the user's aesthetics are enhanced, the discharge of foreign matter collected once is suppressed, and the obstruction of air flow by the foreign matter once collected is suppressed, so that the dust collecting efficiency is improved. It is enhanced, and the density of the foreign material is increased, so that the cycle of discarding the foreign material can be obtained.

Second Embodiment

The second embodiment of the present invention is the same as that of the first embodiment with respect to other parts, but differs only in the configuration of the first chamber sealing portion 415. Therefore, for the matters which are not explained in detail in the description of the present embodiment, those related to the first embodiment are used as they are.

9 is a sectional view of a dust collecting unit according to a second embodiment.

Referring to FIG. 9, the other parts are the same as those of the first embodiment, except that the configuration of the first chamber sealing portion 415 further discloses a configuration for optimizing the generation position of water droplets and efficiently using cold air. There is a difference in being.

In detail, the overall shape of the first chamber sealing part 415 is the same as that of the first embodiment, but the position where the cool air is transferred to the first chamber sealing part 415 is the first chamber sealing part 415. It is limited to the center part and the border part. In other words, the first heat conducting portion 621 formed at the center of the first chamber sealing portion 415 and the second heat conducting portion 622 formed at the edge portion of the second chamber sealing portion 415 are provided. will be. The heat conductive parts 621 and 622 are provided as an article having a high thermal conductivity such as aluminum, so that the amount of cool air delivered from the cooling plate 601 is transmitted to the first foreign matter storage chamber 415 more quickly. Be sure to Of course, since other parts except for the heat conductive parts 621 and 622 are made of plastic, the heat conduction is delayed, so that cool air is mainly transmitted only through the heat conductive parts 621 and 622, and the water droplet is the first. The heat conduction unit 621 and the second heat conduction unit 622 will be generated at an adjacent position.

The first heat conduction unit 621 allows the cool air to be concentrated in the vicinity of the center of the first foreign matter storage chamber 415, because the flow rate of air is weak in the center of the first foreign matter storage chamber 415 This is because water droplets are easily generated.

In addition, the second heat conduction unit 622 is to improve the coarsening of the foreign material located near the inner wall surface by intensively transferring the cold air to an adjacent position of the inner wall surface of the first foreign matter storage chamber 415. . Therefore, when foreign matters accumulate in the first foreign matter storage chamber 415 by centrifugal force, the flow of air is disturbed by foreign matters so that the air flow rate is lowered and the generation of water droplets is advantageous. This is because the generation of water droplets will be further promoted by the insulation of. Further, when water droplets are generated on the inner wall surface of the first foreign matter storage chamber 415 in which a large amount of foreign matters are collected by centrifugal force, more foreign matters can reach the water droplets.

On the other hand, although not shown in the figure, it will be easily guessed that the heat conducting portions 621 and 622 are provided in a circular shape, and the heat conducting portions 621 and 622 are the first chamber sealing portion 415. It can be fixed by insert injection and a separate fastening method.

It is natural that the present embodiment can further enhance the effect of coarsening according to the present invention.

Third Embodiment

The third embodiment of the present invention is the same as that of the first embodiment with respect to the other parts, except that only the relevant configuration of the first chamber sealing portion 415 is different, in particular in a configuration that promotes the transfer efficiency of cold air. There is a characteristic difference. Therefore, in the plural configurations not described in the present embodiment, the configurations of the first and second embodiments are used as they are.

10 is a sectional view of a dust collecting unit according to the third embodiment.

Referring to FIG. 10, other portions are the same as those of the first and second embodiments, except that the thermoelectric module is in contact with the bottom surface of the first chamber sealing portion 415.

In this case, a separate power supply structure for applying external power to the dust collection unit is involved, and the power supply structure is provided in any structure in which power of the vacuum cleaner main body is supplied to the dust collection unit when the dust collection unit is mounted.

According to this embodiment, since a member such as a cooling plate 601 through which cold air supplied from a cooling source passes through is not provided, an advantage of further improving the use efficiency of cold air can be obtained.

Fourth embodiment

The fourth embodiment of the present invention is the same as the first, second, and third embodiments in the other parts, except that the fourth embodiment of the present invention differs only in the configuration of forming cold air. Therefore, the structure which is not specifically described in description of a present Example uses the said 1st, 2nd, and 3rd Example as it is.

11 is a cross-sectional view of a vacuum cleaner according to a fourth embodiment of the present invention.

Referring to Figure 11, in order to operate as a cooling source, the main body of the vacuum cleaner is present in each component constituting the steam refrigeration system. Specifically, a compressor 630 for compressing a refrigerant, a condenser 631 for condensing the compressed refrigerant, an expander 632 for expanding the condensed refrigerant, and an evaporator 633 for evaporating the expanded refrigerant to absorb heat. Included.

Cold air is formed in the evaporator 633 by evaporation of the refrigerant, and the cold air is transferred to the first foreign matter storage chamber 416 via the cooling plate 401 and the first chamber sealing part 415. Water droplets are generated in the first foreign matter storage chamber 416. Of course, the foreign matter is attached by the adhesion of the water droplets and the foreign matter is coarse.

In order to improve the condensation efficiency of the condenser 631, the condenser 631 is preferably provided on the flow path of the main body exhaust port 302 with a high flow rate of air.

According to this embodiment, since the adjustment of the amount of cold air can be quickly performed by the adjustment of the amount of compression by the compressor 630, it is possible to obtain the advantage that the adjustment of the cold air becomes easy according to the necessity of coarse foreign matter. will be.

The present invention is not limited to the embodiments as described above, and those skilled in the art will be able to easily suggest other embodiments within the scope of the same idea. Such embodiments will also be included within the scope of the invention.

For example, instead of the thermoelectric module 610, a cold storage material capable of releasing cold air to some extent may be mounted at the formation position of the thermoelectric module 610. In detail, when the vacuum cleaner is not used, the cold storage material is stored in a freezer compartment, and when the vacuum cleaner is used, the cold storage material of the cold storage material is placed in the mounting position of the thermoelectric module 610. It may be passed to 601 to cause a drop. The cold storage material may be any device in which a large amount of cold air may be stored as an object exemplified by a cool storage pack containing brine.

As described above, since the thermoelectric module and the heat storage material can perform the same function, the two members may be referred to as cooling sources. Of course, such a cooling source may also be an evaporator of the steam refrigeration system as introduced in the fourth embodiment.

In addition, although not described, in order to prevent the cool air generated from the cooling source combining the thermoelectric module, the coolant and the evaporator, the cool air is not lost through other paths toward the first foreign matter storage chamber. It is desirable for the part to be blocked by a predetermined heat insulator.

In addition, the coarsening of the foreign material is performed only with respect to the first foreign matter storage chamber, but the same structure may be adopted for the second foreign matter storage chamber to easily coarse the foreign matter.

According to the present invention, the foreign matter collected in the foreign matter storage chamber is coarse and the density of the foreign matter is increased, so that the efficiency of foreign matter separation is improved.

In addition, the foreign material is coarse to increase the amount of foreign matter that can be collected in the same volume of the foreign matter storage chamber, the user can reduce the cycle of discarding the foreign material can be obtained the advantage that the user's convenience is enhanced.
