Description

Apparatus for drying lanudry by multi-stage differential pressure type and method of the same using reverse osmosis effect and vacuum radiation effect

The present invention relates to a fire protection vacuum radiation drying apparatus for laundry, and more particularly, to a drying apparatus capable of preventing fire by forming a filter layer by the laundry put into a chamber and separating moisture by reverse osmosis effect.

In general, a dryer used for drying various kinds of laundry including clothes is used as a means of drying the laundry using electricity or gas. Such, drying of laundry is usually made through a hot air dryer. The hot air dryer includes an electric hot air dryer and a gas hot air dryer.

The electric hot air dryer described above has a structure in which high-temperature heat is generated by an electric heater, and then the generated high-temperature heat is blown to the laundry to dry in a convection manner. In addition, the gas hot air dryer has a structure in which high-temperature heat is generated by a burner, and the generated high-temperature heat is blown to the laundry to dry in a convection manner.

However, the electric dryer has a problem in that it consumes a lot of electricity because an electric heater must be used, and maintenance and management costs are excessively required due to these disadvantages. In addition, in the case of a gas dryer, since gas must be used as fuel, a large amount of exhaust gas is discharged and a large amount of gas cost is consumed. In particular, there is a risk of environmental pollution due to these disadvantages, and there is a problem in that excessive maintenance and management costs are consumed.

In particular, in the case of an electric dryer or a gas dryer, since a heat source is directly transmitted to the clothes, there is a large problem in the risk of fire due to ignition of the clothes.

FIG. 2 is a perspective view showing a structure in which three chambers are vertically arranged as an embodiment of the drying apparatus shown in FIG. 1 .
3 is a perspective view showing a structure in which three chambers are horizontally arranged as another embodiment of the drying apparatus shown in FIG. 1 .

Hereinafter, a drying apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the drying apparatus 1 proposed by the present invention includes an ejector 3 for spraying air in a jet manner; a first chamber (11) to which a high-pressure vacuum is applied from the ejector (3); a second chamber (13) disposed adjacent to the first chamber (11) and into which laundry is put and dried; a third chamber (15) disposed adjacent to the second chamber (13) and applied with a low vacuum pressure; a heating member (17) provided in the second chamber (13) to supply hot air to dry laundry; A vacuum pump ( 7) and; and fire extinguishing units 19 and 21 for detecting a fire in the second chamber 13 and injecting extinguishing gas when a fire occurs.

In this drying apparatus,

The ejector 3 is connected to the air tank 9 , compresses air to a high pressure, and injects the air into the first chamber 11 . At this time, a pump 23 driven by a motor is connected to the air tank 9 to store air at a constant pressure.

In addition, the first to third chambers 11, 13, and 15 may be disposed in various shapes, but as an example thereof, may be disposed in a vertically stacked structure as shown in FIG. 2 .

That is, the first chamber 11 is disposed at the lowermost end, the second chamber 13 is disposed thereon, and the third chamber 15 is disposed at the uppermost end.

At this time, the first and third chambers 11 and 15 have a hexahedral structure with an empty space formed therein, and support plates 25 and 27 having a mesh structure are respectively disposed on the upper and lower portions of the second chamber 13 .

That is, the lower portion of the second chamber 13 communicates with the first chamber 11 by the lower support plate 25 , and the upper portion communicates with the third chamber 15 by the upper support plate 27 .

Accordingly, the air injected at high pressure from the ejector 3 is supplied to the first chamber 11 through the injection pipe L1, and then is supplied to the second chamber 13, and then continues through the third chamber 15. can be discharged outside.

In this process, the laundry injected into the second chamber 13 may be dried by the air sprayed at high pressure.

The second chamber 13 includes a case (Case) 31 forming an exterior; a lower support plate 25 disposed under the case 31 and communicating with the first chamber 11; an upper support plate 27 disposed on the case 31 and communicating with the third chamber 15; It is rotatably disposed inside the case 31 to rotate the laundry, and includes a rotating body 29 for discharging moisture from the laundry by centrifugal force.

The rotating body 29 is rotatably disposed on the upper side of the frame disposed on the bottom of the case 31 . Then, the rotating body 29 is connected to the motor and rotates when the motor is driven to rotate the laundry.

At this time, the rotating body 29 can effectively rotate the laundry by protruding at least one wing from the outer circumferential surface.

In addition, since the rotating body 29 occupies only a partial area when disposed on the bottom of the case 31 , the air supplied from the first chamber 11 can be sufficiently introduced into the second chamber 13 .

Accordingly, the laundry injected into the second chamber 13 may be dried by centrifugal force by the rotating body 29 and high-pressure air passing through the second chamber 13 .

At this time, since the laundry put into the second chamber 13 has a fibrous structure like a fabric or knitted fabric, it functions as a kind of filter for high-pressure air.

That is, some of the high-pressure air passes through the laundry, and another part passes after repeating the process of colliding with the laundry. A pressure gradient is formed.

Accordingly, the drying process for laundry can be performed more efficiently.

In addition, the laundry can be dried by hot air as well as centrifugal force and high pressure air, and the second chamber 13 is provided with a heating member 17 to spray hot air at a predetermined temperature to the laundry.

The heating member 17 is disposed on the inner upper portion or lower portion of the second chamber 13, and can spray hot air by various methods, for example, a heating coil method, a thermoelectric element method, and the like.

Accordingly, the laundry inside the second chamber 13 may be dried by hot air.

On the other hand, a pipe line L2 is disposed in the third chamber 15 , and one side of the pipe line L2 is connected to the third chamber 15 and the other side is connected to the air tank 9 . Then, the vacuum pump 7 is disposed on the pipe line L2.

Accordingly, when the vacuum pump 7 is driven, a negative pressure is generated inside the third chamber 15 , and this negative pressure also acts on the second chamber 13 , so that the laundry injected into the second chamber 13 is removed. The dehydrated water may be sucked into the conduit L2.

Also, since the inside of the second chamber 13 is in a dry state, fire extinguishing units 19 and 21 are provided to prevent this from occurring.

The fire extinguishing units 19 and 21 include a detection sensor 19 disposed inside the second chamber 13 to detect whether a fire has occurred; When a fire signal is received by the detection sensor 19, it includes an injector 21 for injecting extinguishing gas.

More specifically, the detection sensor 19 includes various types of sensors capable of detecting fire, for example, a heat sensor for detecting fire by detecting heat, or a photosensor for detecting smoke. etc.

And, the signal received by the detection sensor 19 is transmitted to the injector 21, and the injector 21 determines that a fire has occurred and extinguishes the fire when heat or smoke is generated over a certain temperature by this signal. The gas is injected into the second chamber 13 .

Meanwhile, another embodiment of the drying apparatus 1 is illustrated in FIG. 3 . In this embodiment, there is a difference in that the first to third chambers 11 , 13 , and 15 are horizontally arranged.

That is, the first chamber 11, the second chamber 13, and the third chamber 15 are arranged in this order from the ejector 3 direction, and the structures of the first and third chambers 11 and 15 are is the same as the above-described chamber, there is a difference in the structure of the second chamber (13).

The second chamber 13 includes a case 31 forming an exterior; a first support plate 25 disposed on one side of the case 31 and communicating with the first chamber 11; a second support plate 27 disposed on the other side of the case 31 and communicating with the third chamber 15; a rotating body 29 which is rotatably disposed inside the case 31 to rotate the laundry to discharge moisture from the laundry by centrifugal force; a heating member 17 disposed on the upper portion of the case 31 to spray hot air into the case 31; It includes a transfer pipe (L3) for transferring moisture generated in the second chamber (13) to the third chamber (15) by connecting the lower part of the case (31) and the lower part of the third chamber (15) of the second chamber (13) do.

In the second chamber (13), the first support plate (25) and the second support plate (27) are formed in a mesh structure.

In addition, the first support plate 25 communicates with the first chamber 11 , and the second support plate 27 communicates with the third chamber 15 .

Accordingly, the air injected at high pressure from the ejector 3 may be supplied to the second chamber 13 through the first chamber 11 and then discharged to the outside through the third chamber 15 .

In this process, the laundry injected into the second chamber 13 may be dried by the air sprayed at high pressure.

At this time, since the laundry put into the second chamber 13 has a fibrous structure like a fabric or knitted fabric, it functions as a kind of filter for high-pressure air.

That is, some of the high-pressure air passes through the laundry, and another part passes after repeating the process of colliding with the laundry. A pressure gradient is formed.

Accordingly, the drying process for laundry can be performed more efficiently.

In addition, the laundry can be dried not only by centrifugal force and high-pressure air but also by hot air. A heating member 17 is provided in the upper portion of the second chamber 13 to spray hot air at a predetermined temperature to the laundry.

As described above, the laundry is dried inside the second chamber 13 , and in this process, the dehydrated moisture falls to the lower side and is transferred to the third chamber 15 through the transfer pipe L3 .

Hereinafter, a process of drying laundry by the vacuum radiation drying apparatus will be described in more detail.

1 and 2 , when the laundry is dried, first, the laundry is put into the second chamber 13 . Then, the ejector 3 and the vacuum pump 7 are driven. Accordingly, the high-pressure air injected from the ejector 3 is injected into the second chamber 13 through the first chamber 11 and the lower support plate 25 , and the upper support plate 27 and the third chamber 15 . ) is discharged to the outside.

At this time, the laundry is put in the inside of the second chamber 13, and the laundry has a fibrous structure such as a fabric or knitted fabric, and thus performs a kind of filter role for high-pressure air.

That is, some of the high-pressure air passes through the laundry, and another part passes after repeating the process of colliding with the laundry. A pressure gradient is formed.

Therefore, the moisture of the laundry can be dehydrated more effectively by the pressure gradient of the reverse osmosis method.

In addition, the rotating body 29 of the second chamber 13 rotates to rotate the laundry, and moisture in the laundry can be dehydrated radially outwardly by centrifugal force.

And, as the heating member 17 operates, hot air of a certain temperature is generated to increase the internal temperature of the second chamber 13 .

As a result, since the pressure gradient by the high-pressure air, the centrifugal force by the rotating body 29, and the hot air by the heating member 17 simultaneously act on the laundry, drying can be performed more effectively.

At this time, the detection sensor 19 provided on the inside of the second chamber 13 continuously detects the internal temperature or the presence of smoke, and the sensed signal is transmitted to the injector 21, so that in case of fire, the injector 21 The extinguishing gas is sprayed from

On the other hand, if the signal received by the detection sensor 19 is determined to be normal, the drying process for the laundry may be completed.
