The present invention relates to a dryer, and more particularly, to a condensate storage structure in which hot and humid circulating air passing through a drying chamber condenses as it passes through a condenser and is collected for discarding the condensate outside the dryer.

In general, a drum type dryer is a device that blows hot air generated by an electric heater or a gas combustion device into a drum to absorb moisture remaining in a drying object and to dry the drying object.

1 is a cross-sectional view schematically showing a general condensation drum dryer.

Referring to Figure 1, the condensation-type drum dryer is configured to control the opening and closing of the cabinet 10, the cylindrical drum 12 formed inside the cabinet 10, and the drum 12 to form an appearance A door 13 and a belt 11 surrounding the outer circumferential surface of the drum 12 are included.

In addition, the motor shaft 21 is connected to the belt 11, the motor 17 is connected to the motor shaft to provide a rotational force, and the rotational force of the motor 17 is connected to the motor shaft 21 A cooling fan 16 that sucks and rotates the indoor air is included.

In addition, a drying fan 18 connected to the motor shaft 21 opposite the cooling fan 16 to circulate air inside the drum, and air sucked by the drying fan 18 may be connected to the drum ( As a passage to be moved to 12, the drying duct 19 is provided with a heat generating unit 20 therein.

In addition, a lint filter 14 formed below the opening through which the door 13 is inserted to filter foreign matter such as lint and the like contained in the wet air discharged from the drum, and air entering the lint filter 14 are condensers (not shown). It further includes a circulation duct 15 which is a passage to be moved to).

Hereinafter, the operation of the dryer will be described.

First, when power is applied to the dryer, the motor 17 rotates, and the heater 20 attached to the drying duct 19 is heated. In addition, the belt 11 connected to the motor shaft 21 rotates to rotate the drum 12. Then, as the drum 12 rotates, the object to be dried in the drum rotates along the inner wall of the drum and falls by its own weight when it reaches the uppermost side. Here, the object to be dried is lifted by a lift (not shown) attached to the inner wall of the drum.

On the other hand, the drying fan 18 connected to the motor shaft 21 is operated with the rotation of the motor 17, the circulating air passing through the lint filter 14 is sucked. The sucked air rises along the drying duct 19 and becomes a high temperature dry state through the heater. Then, the hot dry air absorbs the moisture present in the object to be dried while passing through the drum, resulting in a high temperature and high humidity.

In addition, the air of the high temperature and high humidity is again filtered by the lint filter 14 and then moved to a capacitor (not shown) along the circulation duct 15.

In addition, the cooling fan 16 connected to the motor shaft 21 is rotated to suck the indoor air outside the dryer. The sucked indoor air is then passed through a cooling fan 16 to the condenser.

Here, the hot and humid air moved to the capacitor along the circulation duct 15 and the indoor air sucked by the cooling fan 16 and moved to the capacitor pass through the capacitor. In addition, the hot and humid air and the indoor air are not mixed with each other by the shape of the capacitor, and only heat exchange occurs.

Therefore, the high temperature and high humidity air is changed to low temperature and high humidity air while losing heat to the indoor air while passing through the condenser. Then, as the temperature decreases, moisture contained in the air condenses and falls to the bottom of the condenser, and is moved to a sump (not shown) in which condensate is collected.

On the other hand, the indoor air passing through the capacitor takes the heat of the high temperature and high humidity air and converts it into low temperature and high humidity air, and the temperature becomes high.

Here, the condensate collected in the sump is moved to the condensate storage unit formed in the upper portion of the dryer through the condensate pipe.

However, when the condensate fills the condensate reservoir, the condensate overflows. The overflowed condensate flows down the outer wall of the condensate reservoir. In addition, the condensate that flows down the outer wall of the condensate storage unit leaks to the outside of the dryer.

The present invention has been proposed to solve the above necessity, and an object of the present invention is to provide a dryer having a condensate leakage preventing structure for preventing a phenomenon in which condensate overflowed out of the condensate storage unit leaks to the outside of the dryer.

Condensate storage structure of the dryer according to the present invention for achieving the above object is a drawer for storing condensate; And a dispenser in which the drawer is accommodated, wherein the drawer includes a front cover constituting a front portion and a drawer body coupled to the front cover, and the dispenser has a predetermined height on at least one inner wall of the wall in the front-rear direction. At least one drawer spacing rib formed is included.

By the above configuration, the condensate generated in the drying process can be collected separately and discharged at a time.

 Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest.

Figure 2 is a perspective view schematically showing a dry preload equipped with a drawer for storing condensate in accordance with the spirit of the present invention.

Referring to Figure 2, the drawer 100 for storing condensate according to the present invention is located on the top of the dryer, may be mounted on the left or right side of the drum 300, the laundry is accommodated. In addition, the drawer 100 is protected by a drawer protection plate 110 located in the upper shaft portion. In detail, the drum 300 is rotated by the rotation of the belt 310 wound on the outer peripheral surface.

Condensate generated from a condenser (not shown) located at the bottom of the dryer is collected at a sump (not shown) located at the bottom of the dryer, and the condensate collected at the sump is transferred to the drawer 100 through the condensate pipe 400 of the drawer. Is moved.

3A is a front perspective view of the drawer, FIG. 3B is a bottom perspective view of the drawer, and FIG. 3C is a rear perspective view of the drawer.

3A, 3B, and 3C, the condensate storage drawer 100 according to the present invention includes a front cover 120 constituting a front portion, a drawer handle 121 formed to be grooved into the front cover lower side, and A drawer body 130 is formed to extend from the rear surface of the front cover 120 and to form a condensate storage chamber therein.

In detail, a locking hook 150 is formed at an upper portion of the front cover 120 to allow the drawer 100 to be completely in close contact with the dryer. The drawer 100 is inserted into the upper portion of the drawer 100 in contact with the front cover 120 and the drawer body 130 so that the drawer 100 is inserted so that the drawer 100 does not interfere with the top plate (not shown) of the dryer. At least one protrusion 140 is formed.

On the other hand, the pressing protrusion 140 is preferably inclined at a predetermined angle to the surface in contact with the upper surface of the insertion hole into which the drawer 100 is inserted, so that it is inserted smoothly when the drawer 100 is pushed in. .

In addition, the locking hook 150 has elastic grooves 151 formed on both sides in order to have an elastic force. Therefore, when the drawer 100 is pushed into the top plate and then the drawer 100 is fully inserted, it rises again to its original position. As a result, the locking hook 150 rises to its original position and is caught by an upper inner surface of an insertion hole (not shown) into which the drawer 100 is inserted, so that the drawer 100 is not detached from the dryer.

In addition, since the push protrusion 140 has a shape in which a central portion rises, the drawer 100 is pressed downward when it comes in contact with the top plate of the dryer. Therefore, the phenomenon that the front cover 120 interferes with the top plate is eliminated.

Here, the push protrusion 140 may be located at the central side or both sides of the upper side of the drawer body 130, but the formation position and shape is not limited to the embodiment of the present invention.

In addition, in order for the drawer body 130 to be coupled with the front cover 120, a plurality of engaging protrusions 122 are formed at an upper side of the front surface at which the drawer body 130 starts, and the locking hook 150 is formed. A coupling groove 123 for inserting the coupling protrusion 122 is formed in the upper side of the front cover 120 is formed.

On the other hand, the upper end of the drawer body 130, the upper end of the overflow control unit 160 is connected to the condensate pipe 400 for moving the condensate collected in the sump.

The overflow control unit 160 receives the condensate drop groove 161 receiving the condensate falling from the condensate pipe 400 and the condensate overflowed when the condensate is filled inside the drawer 100. An overflow storage unit 162 and a siphon generating unit 163 for sending the overflowed condensate back to the sump are formed.

The overflowed condensate flows into the siphon generator 163 and flows back to the sump by the siphon principle.

The siphon principle refers to a phenomenon in which a liquid is pushed into a tube due to an atmospheric pressure acting on a high liquid level. The above principle allows a liquid to flow through a tube from a high place to a low place without tilting the container. can do. In addition, a bottom surface of the overflow control unit 160 includes a bypass tube 164 that vertically penetrates the drawer body 130. Condensate overflowed through the bypass tube 164 flows to the sump.

In detail, in the substantially central portion of the drawer body 130, a long hole formed penetrating the inside of the drawer chamber from the upper side to the lower direction, and a long hole formed penetrating the inside of the drawer chamber from the bottom to the upper side, do not communicate with each other. The shape support 131 of the structure is provided. This is because when the drawer body 130 is manufactured in an injection method, since the inside of the drawer body 130 forms a hollow portion, the upper and lower surfaces of the drawer body 130 are prevented from being struck down. To do this. In other words, to maintain the shape of the drawer body 130 during injection molding.

In addition, the bottom of the drawer body 130 is formed to form a curved surface. This is because the drawer 100 is located on one side of the drum 300, and thus the shape of the bottom of the drawer is determined along the shape of the outer peripheral surface of the drum.

In addition, the end of the drawer body 130 has a condensate pipe receiving curved surface 165 having a concave shape in order to accommodate the condensate pipe 400 is formed.

Figure 4a is an enlarged perspective view showing a water flow preventing structure formed on the side of the condensate storage drawer according to the spirit of the present invention, Figure 4b is an enlarged perspective view showing a water flow preventing structure formed on the bottom of the drawer.

When the condensed water is filled inside the drawer 100, the condensed water overflows through the condensed water drop groove 161 provided in the overflow controller 160 as described above. The overflowed condensate is accumulated in the overflow storage unit 162, and the accumulated condensate flows out into a gap formed in the bottom surface of the siphon generator 163. Then, it is returned back to the sump through the bypass tube 164 connected to the gap.

However, when the amount of condensate overflowed through the condensate drop groove 161 is greater than the amount of condensate going to the sump through the overflow storage unit 162, the overflowed condensate is the drawer body 130. ) It flows down the outer wall.

Here, since the drawer body 130 is in contact with the inner wall of the dispenser (to be described later) that accommodates the drawer 100, the drawer body 130 flows through the wall surface to the drawer front part. Then, the condensate flowing to the drawer front portion is leaked to the outside of the dryer.

In order to solve the above problems, the water flow prevention structure as shown is provided.

In detail, the side drawer recess 170 which forms a vertical groove is formed on the side surface of the portion provided with the overflow controller 160. Therefore, the condensed water overflowed through the condensate drop groove 161 falls directly onto the bottom of the dispenser. As a result, the phenomenon of flowing to the front side of the drawer by removing the outer circumferential surface of the drawer body 130 is eliminated.

In addition, a bottom drawer recess 180 having a groove is formed on the bottom of the drawer in which the bypass tube 164 is formed along the curved surface of the bottom of the drawer.

Condensate that flows down the recesses 170 and 180 is collected at the bottom of the dispenser. In addition, a groove is formed in the bottom surface of the dispenser, and a pipe is coupled to the groove and the pipe is connected to the sump, so that the condensate is moved back to the sump.

In addition, a dispenser depression 210 is formed at a substantially end of the bottom surface of the dispenser 200 to be recessed to a predetermined depth.

By forming the dispenser depression 210, the condensate overflowed from the drawer 100 is collected and flows to the front side of the drawer through the bottom of the drawer to prevent leakage to the outside of the dryer. And, the drawer bottom surface is preferably formed to be slightly inclined downward toward the rear from the front. This is to prevent the overflow of the overflowed condensate forward.

On the other hand, the inside of the dispenser 200 is formed such that the side wall 232 of the side in contact with the drum 300 is curved with the same curvature as the circumference of the drum. In addition, the opposite side wall 230 is formed vertically, the upper end is provided with a fastening rib 230 for fastening the drawer protection plate 110.

In addition, the dispenser bottom surface has a dispenser inclined surface 220 which is formed to be slightly inclined toward the rear side as described above, and a dispenser depression 210 which is recessed from a predetermined point of the inclined surface 220 to the rear end.

In detail, a drawer insertion detecting protrusion 250 is formed on a bottom surface of the dispenser recess 210 to detect how much the drawer 100 is inserted.

The drawer insertion detecting protrusion 250 is formed slightly higher than the bottom surface of the dispenser at the position where the dispenser recess 210 starts. Therefore, the drawer 100 is inserted along the bottom surface of the dispenser and is caught by the drawer insertion detecting protrusion 250. Then, the user senses that the drawer 100 has been inserted almost to the end.

The drawer insertion detecting protrusion 250 is preferably formed such that the surface in contact with the drawer 100 is inclined, so that the drawer 100 can be gently pushed up. For example, the shape of the trapezoid is possible, but the shape of the drawer insertion detecting protrusion 250 is not limited to the embodiment of the present invention.

In addition, a condensate pipe accommodating part 240 in which the condensate pipe 400 is accommodated is formed on the rear side wall of the dispenser 100 to protrude inward. In order to prevent interference with the condensate pipe accommodating part 240, the condensate pipe accommodating curved surface 165 may be formed to concave the end of the drawer 100.

On the other hand, since the dispenser side walls 230 and 232 are in contact with the outer circumferential surface of the drawer, in order to solve the problem that the condensed water overflowed from the drawer 100 may flow to the front part through the wall, the side surface. Walls 230 and 232 may be formed with a plurality of drawer spacing ribs 279 extending long before and after.

In addition, the drawer spaced rib 270 may be formed to have a predetermined height and long forward and backward, or as illustrated, a plurality of short ribs may be formed at regular intervals. And, it is apparent at the level of those skilled in the art that the separation rib 270 may be formed at least one line. In addition, the portion where the spaced rib 270 starts is formed to form a rounded curved surface, so that the drawer 100 is inserted smoothly when inserted. Here, the formation position, the number and the length of the drawer spaced rib 270 is not limited to the embodiment of the present invention, it will be apparent that various numbers and shapes can be proposed.
