The present invention relates to a heat exchange unit cleaning device for a dryer, and more particularly, when foreign matter contained in the air discharged after drying the dry matter on the fin of the heat exchanger, the foreign matter is physically brushed to remove the brush, It relates to a heat exchange unit cleaning device for a dryer that can clean the brush after this progress.

Typically, a dryer is a device that performs drying on a drying object by blowing hot air generated by a heater into a rotary drum to absorb moisture of the drying object (for example, clothes in a state where washing is completed).

The dryer is largely classified into an exhaust type dryer and a condensation dryer according to a treatment method of wet air containing moisture generated by drying the drying object. In detail, the exhaust dryer uses a method of discharging the humid air discharged from the drum to the outside of the dryer, and the condensation dryer dries the moisture from the drum in a heat exchanger to remove moisture and then removes moisture. The air is heated again and sent to the drum for recycling.

Among these, in the case of the condensation type dryer, the drying air after drying the drying object such as clothes is discharged through the flow path to the heat exchanger side. At this time, the discharge may be made by a blowing fan.

However, the air after drying the dried object such as clothing contains a certain amount of moisture, and also contains foreign matter such as lint generated from the clothing.

When the foreign matters are attached to the fins of the heat exchanger after the air flows to the heat exchanger after drying, the foreign matters have a problem of decreasing the heat exchange performance of the heat exchanger.

Accordingly, in the related art, a filter is provided at the front end of the flow path so as to be located in front of the heat exchanger.

However, in the case of installing the filter as described above, it is possible to improve the filtering performance by increasing the mesh of the filter, but inversely, there is a problem that also decreases the heat exchange performance by reducing the amount of air flow flowing.

In addition, conventionally, a method of spraying and removing foreign substances adhering to fins of a heat exchanger by receiving direct water from the outside and spraying them is used. However, in the case of using the direct water, since the direct water must be introduced into the dryer from the outside, there is a problem in that the apparatus is complicated, and there is also a problem that the inside of the apparatus is damaged by water pressure.

In addition, conventionally, a method of spraying condensate generated during heat exchange with a spray nozzle on a fin of a heat exchanger and recycling the same is used.

However, since the foreign matter removed by the water injected and attached to the fin of the heat exchanger may be included in the condensate again, the foreign matter may be caught in the spray nozzle during recycling, thereby causing the nozzle to be clogged. In addition, the condensate to be recycled is continuously contained in the foreign matter such as lint, such that when the recycled condensate is injected into the fin of the heat exchanger, there is always a problem that the fin of the heat exchanger can be recontaminated.

Accordingly, the brush 652 may be returned to its original position by forming the secondary cleaning state as described above and by the lifting operation of the lifting unit 600.

Referring to FIG. 10, when the operation of the lifting unit 600 is completed as described above (S60), the controller 920 operates the discharge pump 820 (S70). Therefore, the discharge pump 820 pumps the condensed water including the foreign matter stored in the storage container 830 to be discharged to the outside through the discharge passage 810. Accordingly, the condensate containing the foreign matter may be discharged to the outside.

In addition, the controller 920 may discharge the condensed water to the outside until it becomes equal to the measured level value and the reference level value.

In addition, in the present invention, since the cleaning unit 650 for cleaning the fins 211 of the evaporator 210 may be old during a predetermined number of times, it may also inform the outside of the replacement time.

Accordingly, the control module 900 according to the present invention may further include a counter 950 and an alarm generator 930.

The counter 950 is electrically connected to the controller 920, and counts the number of operations of the elevating unit 600 in real time, and the controller 920 may store it. Here, the one-time operation of the lifting unit 600 is a one-time lifting operation of the cleaning unit 650. In other words, this may mean one cleaning cycle.

Therefore, when the stored count reaches a preset reference count, the controller 920 transmits an electrical signal to the alarm generator 930, and the alarm generator 930 alarms for a replacement time of the cleaning unit 650. You can inform outside.

In addition, the controller 920 may be electrically connected to the indicator 940 installed in the dryer to visually display a message about a replacement time through the indicator 940.

In addition, the heat exchange part 200 may be further provided with a window (not shown) for monitoring the cleaning part 650 from the outside, and may be further provided with a retractable rotating door (not shown). Therefore, it may be possible to open the door to perform the airborne work on the cleaning unit 650.
