Description

Temperature and humidity controlling apparatus of the dryer

The present invention relates to a dryer, and more particularly, to an apparatus for controlling the temperature and humidity of a dryer.

In general, a clothes dryer is a device that blows hot air generated by a heater into a drum to absorb moisture of a drying object and to dry the drying object. Treatment of wet air generated by drying a drying object by absorbing moisture According to the method, it is classified into exhaust type clothes dryer and condensation clothes dryer.

Exhaust type clothes dryer uses a method of exhausting the humid air discharged from the drum to the outside of the dryer. However, an exhaust duct for exhausting the vaporized water in the drum to the outside is required, and in particular, since the combustion product carbon monoxide and the like are exhausted, there is a disadvantage in that the exhaust duct must be extended to be installed outside.

On the other hand, the condensation type clothes dryer uses a method of condensing the humid air exhausted from the drum in the heat exchanger to remove moisture, and then sending dry air from which the moisture is removed back to the drum to recycle. However, it is not easy to use gas as a heat source because dry flow forms a closed loop.

The ductless dryer is a dryer that overcomes the disadvantages of the exhaust type clothes dryer and the condensation type clothes dryer. That is, the ductless dryer can be maintained at low cost by using gas as a heat source, and there is an advantage of not having to install a separate exhaust duct extending to the outside.

On the other hand, the above-described ductless dryer includes a filter for filtering the lint (Lint) contained in the air coming out of the drum. However, the conventional ductless dryer has a problem that the lint comes out through the gap of the filter is installed.

For example, in the case of a screen filter (Screen Filter), the screen filter is made of plastic and the portion where the screen filter is installed is made of iron plate, so that the material is different from each other, so that the sealing is not accurate. As another example, in the case of a butterfly filter, lint leakage occurs due to a lack of a sealing structure of a portion in which the butterfly filter is installed.

The leaked lint is introduced into the heat exchanger together with air. Lint introduced into the heat exchanger is accumulated on the surface of the heat exchanger, in particular the heat exchanger. Then, the heat exchange efficiency of the heat exchanger may be lowered. Removal of foreign substances such as lint accumulated in the heat exchanger is required.

An object of the present invention is to provide an apparatus for controlling the temperature and humidity of a dryer having a structure capable of removing foreign substances such as lint and the like introduced into the temperature and humidity control apparatus.

An apparatus for controlling the temperature and humidity of a dryer according to an aspect of the present invention, in a dryer capable of drying a drying object accommodated in a drum,

A temperature and humidity control unit for adjusting at least one of a temperature and a humidity of the gas via the drum; And cleaning means for cleaning the temperature and humidity control unit.

Foreign matter such as lint accumulated in the heat exchange part may be removed through the cleaning pipe. Therefore, the cleaning of the heat exchanger can be easily performed without disassembling the dryer body, and the heat exchange efficiency of the heat exchanger can be improved by performing such cleaning.

Moreover, according to the temperature-humidity control apparatus of the said dryer, since the opening-and-closing means which opens and closes a cleaning hole is installed, a cleaning hole can be opened only at the time of a cleaning request, and can normally keep it closed. Therefore, the airtightness in the adjusting part case can be maintained, so that access for cleaning to the heat exchange part can be facilitated while the operating efficiency of the heat exchange part is not lowered.

In addition, according to the temperature and humidity control device of the dryer, as the cleaning pipe portion is formed, the external cleaner is connected to the cleaning pipe portion, it is possible to perform cleaning for the heat exchanger, the cleaning operation can be made more easily. .

In addition, according to the temperature and humidity control device of the dryer, when the flexible pipe is disposed in the cleaning pipe portion, when the external cleaner is connected and operated, the flexible pipe may be deformed by the suction force of the cleaner inside the control unit case. have. Therefore, foreign matter can be more smoothly removed from within the adjuster case.
