The present invention relates to a vacuum cleaner, and in detail, to reduce the volume of the foreign matter collected in the dust collecting unit of the vacuum cleaner, to improve the dust collection efficiency of the foreign material and the use period of the vacuum cleaner, further improve the visual image It relates to a vacuum cleaner so as to enhance the aesthetics of the user.

A vacuum cleaner is a home appliance that cleans an indoor environment by filtering external members by a predetermined filtering member while foreign air is forcibly sucked by the suction force generated by a fan and a motor.

On the other hand, the filtering mechanism for filtering foreign matter from 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 dust collecting unit to filter foreign matter during the cyclone flow of air. There is this. In recent years, a cyclone dust collecting unit that can be used semi-permanently 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 matters, and a water storage chamber in which foreign matters separated from the foreign matter separation chamber are stored. With this structure, foreign matters separated from the foreign matter separation chamber continue to accumulate in the foreign matter storage chamber, and foreign matters are stored in a predetermined volume or more and discarded to the outside by the user when the efficiency of cleaning decreases. In addition, when the foreign matter collected in the foreign matter storage chamber is not discarded at an appropriate time, there is a problem that the dust collecting efficiency of the cleaner is lowered, and there is a problem that is not good.

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 material is excessively large while the amount of the foreign matter accumulated in the inside of 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 accumulate in the foreign material separating chamber, and thus, the efficiency of foreign material separation decreases, and the aesthetics observed from the outside are not good. have.

This problem becomes more apparent when the foreign matter collected in 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 the fine foreign matter does not fall on the inner wall of the foreign matter storage chamber, and the collected fine foreign matter is discharged to the room to re-exhaust the indoor environment again. There is a problem of contamination.

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 user can reduce the cycle of discarding the foreign material more convenient to use the vacuum cleaner The object of the present invention is to propose a vacuum 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 cooling source for generating cold air; A dust collecting unit receiving the cold air; And a cooling rod protruding to a predetermined height into the dust collecting unit so that water droplets are generated on the outer surface by the cold air.

According to another aspect of the present invention, a vacuum cleaner includes 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 inside the dust collecting unit and storing foreign matters collected therein; Cooling rods protruding into the foreign matter storage chamber; And a cooling source supplying cold air to the cooling rods to generate water droplets on the outer surface of the cooling rods.

Vacuum cleaner according to another aspect of the present invention comprises a cooling source for generating cold air; A heater generating heat; And a dust collecting unit configured to form water droplets inside the cold air to coarsen the collected foreign matter and to evaporate the water droplets by the heat, thereby increasing the coarsening of the foreign material.

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. And, the upper surface of the cover 200 is formed with a movable handle 201 which can be rotated 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 and outside air is introduced therein, 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.

In addition, a cooling rod 601 is formed on a lower surface of the second base 150 that the lower surface of the dust collecting unit 400 touches, and the cooling rod 601 is inserted into the dust collecting unit 400. . The cooling rod 601 is a cold portion itself, so that the outer surface of the cooling rod 601 is colder than the surroundings, thereby forming dew, that is, water droplets on the outer surface of the cooling rod 601.

In this way, the dew, which is formed on the outer surface of the cooling rod 601, that is, water droplets (water) causes the foreign matter to be agglomerated by its own adhesive force, thereby increasing the size of the fine foreign matter. In other words, since the high adhesion water droplets are provided in the space in which the foreign matter flows inside the dust collecting unit 400, the fine foreign matter is attached to the water droplets so that even after the water droplets evaporate, the foreign matter is coarse. The fine foreign matter is maintained in a high density state.

In this case, after the water droplets are evaporated, the coarse foreign matter adhering to the inner wall of the cooling rod 601 and the dust collecting unit 400 falls and accumulates in the inner space of the foreign matter storage chamber, wherein the dust collecting unit 400 The foreign material collected inside will be coarse and denser.

On the other hand, the cooling rod 601 can take a long foreign material such as hair, it is possible to further proceed the operation that the foreign material is coarse by water droplets. And, in order for the heat transfer to the cooling rod 601 to occur quickly, the material of the cooling rod 601 is preferably made of a high thermal conductivity metal, which can be exemplified by aluminum. In addition, in order to increase the efficiency of water droplet formation, it is preferable that the outer surface of the cooling rod 601 is formed to be smooth, that is, low illuminance.

The cooling rod 601 provides cold air. The thermoelectric module 602 is a module for moving heat by using electricity as an energy source by using the Peltier effect. The surface facing the cooling rod 601 becomes a cooling surface and the opposite surface, that is, the internal space is radiated. Operated into space

When the operation of the thermoelectric module 602 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 side where the endothermic phenomenon occurs becomes the cooling surface, and the cooling rod 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 rod 601 by the power applied from the outside.

5 is an exploded perspective view of the vacuum cleaner body according to the present invention.

Referring to FIG. 5, the second base 150 is placed on the front side of the first base 110, and the motor housing 300 is placed on the rear side. Then, the cover 200 is sequentially covered to form a 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 heat dissipation hole 603 is formed at a position corresponding to the cooling rod 601 in the first base 110 to discharge heat generated from the thermoelectric module 602 to the outside. Hot air is discharged from the heat generating surface of the thermoelectric module 602 through 603.

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, in order to coarsen the foreign material collected in the first foreign matter storage chamber 416, the insertion hole 610 is inserted into the cooling rod 601 at a predetermined position of the first chamber sealing portion 415 The insertion hole 610 is formed and blocked by a plurality of diaphragms 611. Here, the diaphragm 611 is made of soft rubber, and when the cooling rod 601 is inserted, it is softly deformed so that the cooling rod 601 is inserted into the first foreign matter storage chamber 416. When the cooling rod 601 is pulled out, the outer surface of the cooling rod 601 may be swept away so that the coarse foreign matter adhering to the outer surface of the cooling rod 601 does not leak to the outside of the first foreign matter storage chamber 416. Be in the interior space. To this end, the insertion hole 610 is of course provided at a position corresponding to the position of the cooling rod 601.

FIG. 7 is an enlarged view of portion “A” of FIG. 6, and with reference to FIG. 7, the structures of the insertion hole 610 and the diaphragm 611 will be clearly understood.

Referring back to FIG. 6, the chamber sealing parts 415 and 402 allow each of the lower side surfaces of the foreign matter 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. 8 is a cross-sectional view taken along line II ′ of FIG. 3, with reference to FIG. 8 to describe the internal structure of the dust collecting unit 400 and the operation of the dust collecting unit in detail.

First, as described in detail with reference to FIG. 6, 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. As described above, the first chamber sealing part 415 is provided with an insertion hole 610 through which the cooling rod 601 can be inserted and a diaphragm 611 blocking the insertion hole 610. have.

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 applied in this way because the dust collecting unit side suction port 401 is located on the upper side, the cyclone flow of the high speed rotation occurs in the upper portion of the conical filter 405, and the relatively low speed in the lower portion. Because cyclone flow occurs. That is, in the high-speed cyclone flow, the foreign material is rotated more outwardly, but in the low-speed cyclone flow, the foreign material is spread more inward, so that the filter member is applied in a conical shape to filter the foreign material. desirable.

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 with respect to the foreign matter once collected, thereby eliminating the phenomenon of the foreign matter being lifted up. .

On the other hand, water droplets are formed on the outer surface of the cooling rod 601, and because the foreign matter coarse by the water droplets, the phenomenon that the foreign matters can be further suppressed. 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 when water droplets evaporate, the foreign matter remains coarse, so that the volume of the fine foreign matter decreases and thus the cycle of discarding the fine foreign matter is reduced. Longer, the flow resistance of the air due to 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.

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, the air filtered by foreign matter by two cyclone flows is introduced 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).

Meanwhile, 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.

In addition, the inner surface of the lower end of the exhaust portion 407 is formed in contact with the guide ribs 459. As such, the exhaust portion 407 is supported by the guide ribs 459, thereby preventing external impact. It is possible to obtain the advantage that the strength of the base 407 is enhanced. The guide rib 459 will be described in more detail.

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.

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

Referring to FIG. 9, the second foreign matter storage chamber 417 is provided extending downward from the dust collecting body 406 in a predetermined shape.

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 accommodating foreign materials and to allow foreign materials to be rotated in the first foreign matter storage chamber 416.

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 generate mutual air flow.

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

Referring to FIG. 10, first, the operation of the vacuum cleaner of the present disclosure will be described based on the inflow and outflow paths of foreign substances, 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 inlet 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 602, because the endothermic phenomenon occurs on the outer surface facing the cooling rod 601, the cooling rod 601 is finally cooled. The inner surface provided on the opposite side of the outer surface generates heat and heat is discharged to the outside through the heat dissipation hole 603.

In addition, the cold air delivered to the cooling rod 601 generates water droplets on the outer surface of the cooling rod 601 by the temperature difference between the outer surface of the cooling rod 601 and the outside air. Of course, since the foreign matter is attached to the water droplets, the foreign material is coarsened around the water droplets. In addition, when the amount of cold air is controlled by adjusting the supply current and the size 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.

This transfer of cold air continues to occur during the operation of the vacuum cleaner, so that the coarsening of foreign matter continues. Thereafter, after the operation of the vacuum cleaner is finished, the direction of the current applied to the thermoelectric module 602 is reversed so that the cooling rod 601 is operated as a heating plate to promote the evaporation of 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 thermoelectric module 602 is not reversed, water droplets may be naturally evaporated by heat transferred 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.

Meanwhile, although not described in detail, the number of the cooling rods 601 may be appropriately provided to adjust the amount of water droplets generated.

FIG. 11 is an enlarged view of “B” of FIG. 10. Referring to FIG. 11, the cooling rod is inserted through an insertion hole 610 formed in the first chamber sealing part 415 when the dust collecting unit 400 is seated. 601 is inserted, and foreign matter stored in the foreign matter storage chamber by the diaphragm 611 is not leaked to the outside. In addition, when the dust collecting unit 400 is removed by the diaphragm 611, the foreign matter stuck to the outer surface of the cooling rod 601 is wiped by the diaphragm 611 so that the foreign matter is moved outward along the cooling rod 601. Leakage is prevented.

The diaphragm 611 may be fixed to the first chamber sealing part 415 by using a soft rubber as a material.

Second Embodiment

The second embodiment of the present invention is the same as that of the first embodiment for the other parts, except that the heater is further attached to the cooling rod 601 to be used for the purpose of quickly drying the coarse foreign matter attached to the water droplets. do. In other words, when only the amount of heat generated when the positions of the heat absorbing side and the heat generating side of the thermoelectric module 602 are reversed is insufficient, the amount of heat for evaporation of the water droplets is insufficient, so that the water droplets are dried more quickly by the heater supply heat.

FIG. 12 is a cross-sectional view of the cooling rod according to the second embodiment, and it can be easily seen that the heater 604 is involved in the contact surface of the thermoelectric module 602 and the cooling rod 601.

According to this embodiment, there is an advantage that the coarsening of the water droplets is more reliably performed by causing the water droplets to evaporate quickly.

Included.

Cold air is formed in the evaporator 623 by evaporation of the refrigerant, and the cold air is transferred to the outer surface of the cooling rod 601 to form water droplets on the outer surface. Of course, foreign matter is attached by the adhesion of the water droplets, it is natural that the foreign material is coarse. Therefore, in the case of this embodiment, the evaporator 623 is operated as a cooling source.

In order to improve the condensation efficiency of the condenser 621, the condenser 621 is preferably provided on the air flow path to 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.

In addition, when the dust collecting unit 400 is seated inside the vacuum cleaner body 100, the thermoelectric module 631 may be inserted into the cooling rod 630.

In addition, although the direction of the current supplied to the thermoelectric module 631 is reversed, the role of the cooling rod as the heating rod by the thermoelectric module may be performed to allow water droplets to evaporate. However, in order for water droplets to evaporate more quickly to further enhance the coarsening of foreign matter, a heater 632 is further formed on one surface of the thermoelectric module 631, and the heater 632 is operated when the operation of the vacuum cleaner is stopped. The cooling rods can be made to serve as the heating rods.

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