To reduce the space for installing the space utilization is higher, and at the same time the thermal efficiency of the fabric dryer.

Fibers for making various kinds of clothes, that is, fabrics are woven with weft and warp intersected with each other. The final fabric which can be used as fabric is manufactured through a number of successive processes including bleaching and dyeing. Is subjected to at least one drying process.

Dryers used in the fabric production line consisting of a plurality of continuous processes as described above, the general method of blowing hot air to the fabric proceeds, look at the dryer to dry the fabric using hot air as follows.

The conventional fabric dryer has a structure in which a plurality of chambers are arranged in a row, and as shown in FIGS. 1 and 2, each chamber 10 has a housing 11 having a substantially rectangular parallelepiped shape and open at both sides thereof. ; A blowing fan 12 provided at one lower side of the housing 11 and having a driving motor M coupled thereto; A hot air source 13 provided on the other lower side of the housing 11; A hot air supply duct 14 connecting the blower fan 12 and the hot air source 13; It is configured to include a drying duct 15 and the like connected to the blowing fan 12 located in the center of the housing.

And when the plurality of chambers 10 are arranged in a dense line in a row, side walls 20 are coupled to the open front end of the foremost chamber and the open rear end of the rear chamber, respectively, the center of the side wall 20 The fabric passing hole (H) is formed through.

In this case, the hot air source 13 means a means capable of heating air, such as a burner or a radiator.

In addition, the drying duct 15, the upper and lower dry duct member 15A (15B) and the upper and lower dry duct member is positioned at the top and bottom so that the bottom and the upper surface is parallel to each other, and the open side of the upper and lower dry duct member. The duct connecting member 15C which connects the end part, the drying duct 15 has a substantially "C" shape on the side view, and hot air jetting holes are provided on the bottom and top surfaces of the upper and lower dry duct members facing each other. Is provided.

Looking at the process of drying the fabric (T) by the dryer of the above structure, the drying target fabric (T) is introduced into the dryer through the fabric passing hole (H) of one side wall 20 after the plurality of chambers (10) ) And then through the fabric through hole of the other side wall is drawn out of the dryer.

At this time, the fabric T is passed between the upper and lower dry duct members 15A and 15B of the drying duct 15 in the process of passing through each chamber 10, and the hot air generated from the hot air source 13 The fabric is supplied to the drying duct 15 along the hot air supply duct 14 by the blower fan 12, and the fabric is provided through hot air spray holes provided on the bottom and upper surfaces of the upper and lower dry duct members 15A and 15B. Hot air is sprayed on both sides of (T) to dry the fabric (T).

The conventional dryer as described above is supplied with hot air therein, the hot air after drying the fabric is discharged to the outside of the chamber through the exhaust duct, the conventional exhaust duct (D) is generally connected to the outside of the upper surface of the dryer installation do.

Therefore, in the conventional dryer, a dead space is formed on the upper surface of the dryer by the exhaust duct, so that the installation space is unnecessarily expanded and the heat loss is increased due to external exposure, and the dismantling, transportation, and installation of the dryer are easy. It has a hard disadvantage.

The present invention was devised to solve various problems of the conventional fabric dryer, which can minimize the installation space and heat loss, provide easy waste heat recovery, and provide a dryer that is easy to transport and install. There is a purpose.

The above object of the present invention is achieved by embedding the exhaust duct.

In the fabric dryer of the present invention, since the exhaust duct is embedded in the dryer, the installation space is minimized to increase the space utilization, and heat loss through the exhaust duct can be prevented without covering the exhaust duct with a heat insulating material, and waste heat through the exhaust duct. Recovery efficiency is also improved.

And it is easy to assemble, transport and install has the advantage of reducing the installation cost.

The present invention relates to a fabric dryer for solving problems such as a decrease in space utilization due to exhaust ducts, an increase in heat loss, and the like, provided with an exhaust duct installed inside the housing of the dryer.

The fabric dryer of the present invention has a structure in which a plurality of chambers, which are unit dryers, are arranged in close contact with each other and are connected as one. An exhaust duct for discharging hot air used for drying the fabric to the outside is provided inside the chamber. The technical features are combined accordingly.

That is, the dryer of the present invention is composed of a plurality of chambers, and each chamber is provided with exhaust ducts, and when the plurality of chambers are connected in a row to form a single dryer, the exhaust ducts built in each of the adjacent chambers are connected to each other. As a result, the exhaust duct of the entire dryer is formed.

In this case, the number of chambers varies depending on the capacity of the dryer, and if necessary, the length of the chamber may be extended to constitute the dryer with only one chamber.

Dryer of the present invention as described above, a plurality of chambers are arranged in close contact with each other; It is coupled to each open end of the foremost and rearmost chambers, and consists of a pair of plate-shaped sidewalls formed through the fabric through-holes in the center.

Each chamber has a structure in which a blower fan, a hot air source, a hot air supply duct, a drying duct, an exhaust duct, and the like are coupled to the inside of a housing open to both sides in a horizontal direction by forming a substantially rectangular tube.

In addition, the drying duct consists of a tubular duct connecting member which connects each open end of the upper and lower dry duct members and the open and lower dry duct members, each of which has one open end except for a hot air jet. In the shape of a "c".

At this time, the hot air injection port is provided on the bottom surface of the upper drying duct member and the upper surface of the lower drying duct member facing each other in the upper and lower positions, and the lower end of the duct connecting member is connected to the blowing fan together with the lower drying duct member.

The exhaust duct is a passage for discharging the hot air used for drying the fabric, that is, the air inside the chamber, to the outside after being injected through the drying duct while being coupled to the ceiling of the chamber housing. One or more are installed inside the chamber.

In addition, the exhaust duct is a tube having an axial hollow, and a plurality of through-holes are formed in the pipe wall to suck air in the chamber into the hollow. Each exhaust duct of the plurality of chambers arranged in a row is connected to each other, and then the last chamber In and through the side wall or the chamber ceiling is connected to the external exhaust duct.

At this time, it is also preferable to divide the hollow of each exhaust duct so that two or more channels are formed along the axial direction.

The partitioning of the exhaust duct into a plurality of channels as described above allows the air in the chamber to be discharged to the outside through the exhaust duct, and to supply the heated external air to the inside of the chamber using the heat of the discharged air. It is to.

For example, when the hollow of the exhaust duct is divided into two compartment channels, air in the chamber is discharged to the outside through one channel, and external air is supplied into the chamber through the other channel.

That is, through the through-hole of one channel, the air inside the chamber is sucked out and discharged to the outside, the outside air is heated using the inside air of the discharged chamber, and the heated outside air through the through-hole of the other channel is inside the chamber. The reason why the hollow of the exhaust duct is divided into a plurality of compartments is as follows.

The hot air supplied to each chamber of the dryer may be continuously supplied or intermittently supplied according to the set temperature depending on the working conditions. However, if the humidity inside the chamber rises due to moisture evaporated from the fabric, the temperature inside the chamber is sufficient. Nevertheless, the drying efficiency of the fabric is reduced.

Therefore, in order to improve the drying efficiency of the fabric, it is necessary to continuously discharge the air in the chamber where the humidity is high. If the air inside the chamber is discharged without the hot air being supplied, the drying efficiency decreases as the temperature inside the chamber decreases. New hot air must be fed back into the chamber.

At this time, by supplying the new external air heated as heat of the discharged air into the chamber while discharging the hot air inside the chamber, it is possible to prevent the temperature drop due to the discharge of air inside the chamber.

As a result, energy consumption can be reduced by reducing the amount of hot air supplied into the chamber. Therefore, it may be desirable to install the exhaust duct inside the chamber and divide the hollow of the exhaust duct into two or more compartments. There is another technical feature of the present invention in the structure of such an exhaust duct.

Looking at the flow of hot air injected into the fabric in the chamber configured as described above, hot air heated in a hot air source such as a radiator, burner, etc. is sucked by the blowing fan through the hot air supply duct is supplied to one side of the drying duct.

The hot air supplied to the drying duct is sprayed through hot air spray holes provided on the bottom surface of the upper and lower drying duct members, respectively, and the fabric passes between the upper drying duct member and the lower drying duct member. As a result, the fabric is dried, and the hot air used for drying, that is, the air inside the chamber, is discharged through the exhaust duct, and new external air heated by the exhaust air is supplied into the chamber.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

At least one coupled to the housing 110, and consists of an exhaust duct 160 formed through a plurality of through holes (H ') through the tube wall.

At this time, the drying duct 150 is provided with a hot air jet port on the upper surface and the lower drying duct member 151 whose one open end is connected to the blowing fan 120; An upper drying duct member 152 positioned on the lower drying duct member 151 and provided with a hot air spraying port at a bottom thereof, and having one end open; It consists of a duct connecting member 153 connecting the one open end of each of the upper and lower drying duct members 152 and 151 and the blowing fan 120.

In addition, the duct connecting member 153 is a tubular body, and the open upper and lower ends are coupled to the open one side end of the upper and lower dry duct members 152 and 151 and the blowing fan 120, thereby The lower drying duct member and the drying duct connecting member 153 form a "c" shape on the side view, and the hot air supplied from the blowing fan 12 is the bottom surface of the upper drying duct member 152 and the lower drying duct member. It is injected through the hot air jet port provided on the upper surface of (151).

In addition, the hot air dried through the fabric after being injected through the hot air jet port contains water vapor, and if it is not discharged, the humidity of the air inside the chamber is increased to decrease the drying efficiency. Duct 160.

At this time, the water vapor generated in the fabric by the hot air is accumulated from the top in the chamber, the exhaust duct is preferably coupled to the top or ceiling in the housing.

In addition, in the case of arranging a plurality of chambers provided with exhaust ducts in a row, the exhaust ducts 160 of each chamber are connected to each other, and then pass through the side wall 200 or the ceiling of the last chamber in the last chamber to form an external exhaust duct 160 '.

In addition, when the air inside the chamber is discharged to the outside through an exhaust duct coupled inside the housing, new air must be injected into the chamber, and hot air can be supplied through the hot air source as new air. Energy consumption can increase as the temperature inside the chamber becomes higher than necessary.

However, when injecting unheated external air into the chamber, the temperature inside the chamber may drop too much, thereby minimizing the temperature drop of the exhaust air by allowing the internal air of the chamber to be discharged through the inside of the chamber, and reducing the heat of the exhaust air. It is preferable to heat the outside air and then supply it to the inside of the chamber. When the intake duct for supplying the heated outside air is installed outside the dryer, heat loss cannot be prevented even if the duct is insulated.

Therefore, the intake duct for supplying the heated outside air to the inside of the chamber is also preferably installed in the chamber as the exhaust duct.
