Description

Condensed water outlet structure of dryer

The present invention relates to a dryer, and more particularly, to a condensate piping structure for discharging condensate generated in the condenser and collected in the sump to the outside of 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 12, a drying duct 19 having a heating unit 20 therein is included.

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 provided in the upper portion of the dryer, the size of the condensate storage unit is limited. And, the user may forget to empty the condensate stored in the condensate storage unit at the end of drying. In this case, when the dryer is operated again while the condensate storage unit is full of condensate, the condensate moved to the condensate storage unit overflows and returns to the sump again. As a result, condensate continues to circulate in the sump and the condensate reservoir, and the drying stroke of the dryer may be interrupted.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a condensate piping structure of a dryer that allows a user to operate the dryer freely regardless of whether the condensate is empty in the condensate storage unit.

Condensate piping structure of the dryer according to the present invention for achieving the object as described above is formed on the upper side of the base, the sump is collected condensate moved from the condenser; A condensate pipe having one end connected to the sump and flowing the condensate; And a drawer connected to the other end of the condensate pipe to move the condensate collected in the sump along the condensate pipe and stored therein, wherein the condensate pipe is cut at a predetermined position, and the inlet pipe is a cut portion of the sump side. And divided into the outlet pipe is the drawer side cutting portion, and includes a connector for connecting the inlet pipe and the outlet pipe.

By the above configuration, even when the dryer is operated in a state in which the condensate storage unit is full of condensate, the condensate overflows and leaks to the outside of the dryer.

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.

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.

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. The bottom surface of the overflow controller 160 includes a bypass tube (not shown) that vertically penetrates the drawer body 130. The condensate overflowed through the bypass tube 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, the drawer body 130 forms a hollow part, thereby preventing the upper and lower surfaces of the drawer body 130 from hitting 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.
