Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air circulation type / dehumidifying type clothes dryer, and more particularly to a clothes dryer which adopts a water-cooling type dehumidifying mechanism and has a compact structure to enhance dehumidification.

[0002]

2. Description of the Related Art Bathroom clothes dryers and rotary drum dryers have been known as clothes dryers.

Among them, the bathroom clothes dryer has a long drying time and requires a large amount of power consumption, so that there is room for improvement in drying efficiency and economy.

On the other hand, the rotary drum type clothes dryer has a structure in which clothes are rotated in a drum and dried by friction between warm air and clothes. In principle, the clothes dryer is an air cooling type dehumidifying type.

Therefore, although the clothes are moved, there is an advantage that the drying time is shortened, but since the clothes are rubbed against each other, the clothes are easily damaged, and the clothes are rotated in the drum, and a large heat exchange fan is used. Because of this, the driving noise is loud and the device is large.

Further, since the rotary drum type clothes dryer is air-cooled, there is a limit in dehumidification, and because heat is exchanged with the outside air, heat is released to the outside, which causes abnormal environmental temperature and humidity. There was a problem of rising.

In order to solve these problems, do not move clothes,
In addition, a compact air circulation type dehumidification type clothes dryer that has a quiet operation sound has been proposed. This dryer suspends wet clothes in the drying chamber and circulates warm air in the drying chamber. It is a clothes hanging type clothes dryer that dehumidifies clothes.

[0008]

However, among the conventional clothes dryers, the air-circulation type clothes dryer, which is a clothes hanging type that does not damage clothes and has a compact fan and the like, is Although it has various advantages over the drum type clothes dryer, this air circulation type clothes dryer has the disadvantage of low dehumidification and long drying time due to its air-cooled structure, However, the problem that the environmental temperature and the humidity rise excessively has not been solved.

The present invention has been made in view of the above circumstances, and is a hanging type air circulation type clothes dryer for suspending clothes in a drying chamber and circulating air in the drying chamber to dry the clothes. An object of the present invention is to provide a clothes dryer capable of increasing dehumidification, shortening the drying time, and keeping indoor temperature and humidity excellent.

[0010]

In order to achieve the above object, the present invention provides a hot air / dehumidifying unit in a drying chamber, sucks moist air in the drying chamber into the unit, and after the dehumidifying treatment, performs drying. In a clothes dryer for dehumidifying and drying clothes hanging in a drying room by blowing warm air into the room,
The dehumidifying unit is provided with a humid air suction port for sucking the humid air in the drying chamber and a warm air outlet for blowing warm air heated to a predetermined temperature into the drying chamber on the front side of the housing, and the humid air passage of the housing. It is characterized in that a dehumidifying mechanism having a water cooling structure for dehumidifying moist air is incorporated therein.

Here, in the warm air / dehumidifying unit installed in the drying chamber, a humid air inlet is set on the lower side of the front side of the housing, and a warm air outlet is set on the upper side. The warm air fan installed in the room blows warm air heated to a predetermined temperature by the heater into the drying chamber, and the humid air that comes in contact with the damp clothes suspended in the drying chamber enters the housing from the humid air inlet. Inhale and circulate the air in the drying chamber to dry the clothes by dehumidifying.

As the warm air fan, a small axial fan is suitable, and a sensor for preventing the temperature inside the drying chamber from rising excessively is preferably provided in the vicinity of the hot air outlet for safe operation. As the heater, a PTC ceramic heater is preferable because it requires almost no waiting time at the start of operation.

Next, the dehumidifying mechanism of the water cooling structure installed in the housing comprises a water supply means, a dehumidifying part (heat exchange part), and a draining means. The water supplying means is from the water tap to the dehumidifying part. It consists of a water supply hose and a water supply pipe for supplying cooling water to the.

Further, as the dehumidifying section, securing a large contact area with the humid air taken into the housing from the humid air suction port enhances the dehumidifying performance. Therefore, the humid air passage (dehumidifying area) in the unit. ), A structure in which cooling pipes are arranged in a zigzag pattern or along a desired pattern so that the cooling water spreads at a high density,
Further, it is conceivable that a single flat cooling container for storing cooling water is provided, or a plurality of cooling containers are provided in parallel in a passage.

On the other hand, the drainage means is composed of a condensed water receiving tray for storing the condensed water generated in the dehumidifying section and a drain hose for discharging it to an external trap.

Further, it is desirable that a thermistor is installed on the surface of the cooling pipe or the cooling container so that the cooling water can be stored in a dehumidifying temperature range by flowing or stopping the water according to the signal.

As is apparent from the above construction, in the clothes dryer according to the present invention, the humid air in the drying chamber is taken into the unit through the humid air suction port, and the dehumidifying mechanism of the water cooling structure is used for dew condensation to perform dehumidification. Therefore, compared with the conventional air-cooling type dryer, the condensation efficiency is improved and the drying time can be shortened.

Further, as the driving fan installed in the warm air / dehumidifying unit, only a compact warm air fan is required, and the structure can be simplified.

Further, since the dehumidifying mechanism of the water cooling structure is adopted, it suffices to bend the cooling pipe in accordance with a desired pattern or set a flat cooling container, and to use an expensive heat exchange fan or the like. The structure can be simplified compared to the required complicated structure.

In addition, the tap water used for the dehumidifying mechanism is temporarily stopped, and when it reaches a predetermined temperature, it is drained to the outside.
Enables effective use of tap water.

First, as water supply means, cooling water is supplied into a water supply pipe 33 inside the housing 20 through a water supply hose 32 connected to a water supply tap 31 such as tap water, and a branch plug 34 is provided at the end of the water supply pipe 33. The cooling water is supplied through the branch plug 34 into the three rows of cooling pipes 35 arranged in the pattern shown in the humid air passage 25.

The water supply plug 31, the water supply hose 32, the water supply pipe 33 and the branch plug 34 are water supply means, and the cooling pipe 35 is a dehumidifying part.

The cooling pipe 35 may be arranged in a zigzag shape on the left and right sides and sequentially move downward, or may be extended in a zigzag shape on the up and down sides to extend to the left and right sides respectively. The shape may be set so as to move forward.

As described above, the shape of the cooling pipe 35 disposed in the humid air passage 25 has a high density in the humid air passage 25, that is, the cooling pipe so that a large contact area with the humid air can be secured. The length of 35 should be set as long as possible.

Next, as a drainage means, a cooling pipe 35 is used.
The condensed water that has condensed on the surface is drained from the condensed water tray 36 to the drain trap through the drain hose 37a, but the electromagnetic valve 39 is opened and closed by the signal from the water temperature detection thermistor 38 installed on the surface of the cooling pipe 35 to perform heat exchange.

Therefore, when the temperature of the cooling pipe 35 is detected by the water temperature detecting thermistor 38 and the surface temperature of the cooling pipe 35 reaches a predetermined temperature, the electromagnetic valve 39 is opened to drain the water inside the cooling pipe 35 from the drain hose 37b. Since the water is drained to the outside through the water tap and new cooling water is introduced from the water tap 31 into the cooling pipe 35 through the water supply hose 32 and the water supply pipe 33, the amount of tap water is not required so much and the water charge is extremely small.

Since the warm air / dehumidifying unit 10 used in the present invention employs the water-cooling type dehumidifying mechanism 30, the dehumidification can be increased as compared with the conventional air-cooling type.
It is possible to shorten the drying time.

Further, as the driving fan installed in the housing 20, only the compact warm air fan 26 is required, and there is an advantage that the internal structure is simplified.

Next, with reference to FIGS. 4 and 5, the construction of the clothes hanging type clothes dryer 40 in which the warm air / dehumidifying unit 10 is installed in the drying chamber will be described.

As shown in FIG. 4, a cabinet 50 having a predetermined internal volume is vertically divided into two parts by a partition plate 51.

When the power switch, the operation switch, etc. are operated, the warm air fan 26 operates, and the warm air of the predetermined temperature by the warm air heater 27 is blown into the drying chamber A through the warm air outlet 22.

The warm air sent into the drying chamber A circulates in the drying chamber A to dehumidify the clothes, and the resulting humid air is the humid air installed under the front side 20a of the housing 20. It is sucked into the housing 20 through the suction port 21.

Next, the moist air in the housing 20 comes into contact with the cooling pipe 35 arranged in the moist air passage 25,
Condensation is formed on the surface of the cooling pipe 35, the condensed water is collected in the tray 36, and is drained to the drain trap through the drain hose 37a.

Further, the dry air dehumidified by the dehumidifying mechanism 30 is heated by the warm air fan 26 to a predetermined temperature by the warm air heater 27 and is again supplied into the drying chamber A from the warm air outlet 22 to repeat this air circulation. Accordingly, the moist clothes 55 are dehumidified, and particularly, the cooling water is intermittently fed into the cooling pipe 35, and the dehumidification is efficiently performed.

Further, the condensed water that has condensed on the surface of the cooling container 60 is drained from the condensed water receiving tray 36 through the drain hose 37a to the drain trap, and at the same time, the water temperature detecting thermistor 38 installed on the surface of the cooling container 60 causes the solenoid valve 39. The cooling water in the cooling container 60 can be drained through the external drain hose 37b after dehumidifying by operating the cooling pipe 60, and the cooling pipe 35 is used as a mechanism for intermittently supplying the cooling water in the cooling container 60. It is similar to the case.

As described above, it is easier to manufacture the cooling container 60 and to dehumidify a large amount of cooling water by using the flat cooling container 60 for storing the cooling water, as compared with the number of steps for manufacturing the cooling pipe 35. Therefore, there is an advantage that the dehumidifying capacity is increased.
