Description

[0001] The present invention relates to a dry cleaning apparatus capable of performing variable control of an X-

The present invention relates to a dry cleaning apparatus capable of variable X-ray control, and more particularly, to a system and method for measuring the degree of contamination of a cleaning agent of a dry cleaning apparatus with a sensor and detecting the frequency, The present invention relates to a dry cleaning apparatus capable of performing variable control of an X-ray beam that is capable of efficiently projecting an X-ray beam by automatic control.

Dry cleaning is a method of washing laundry in a dry state using a cleaning solvent such as volatile organic compounds (VOCs). Dry cleaning is a washing method suitable for removing volatile grease, and it is mainly used for clothes washing which is liable to be discolored or shrunk by water washing.

The dry cleaning process includes a washing step of immersing the laundry in the volatile washing solvent to remove the washing water from the laundry, a dehydrating step of draining the washing solvent and extracting the remaining washing solvent through centrifugal separation, And blowing hot air to completely remove the cleaning solvent remaining in the laundry by volatilization.

As the volatile cleaning agent, for example, solvent-based cleaning agents and petroleum-based cleaning agents may be used. As the cleaning solvent is used for a long time, odor due to contamination is generated. These odors were confirmed to be caused by the growth of aerobic bacteria entering the washing solvent.

Aerobic bacteria may be caused by the bacteria that are attached to the laundry through the washing process, or the bacteria that are present in the air are condensed into the cleaning solvent by the temperature drop.

A method of irradiating x-rays to sterilize the bacteria introduced into the cleaning solvent has been proposed. However, when the X-ray is projected to the cleaning solvent for a long time at a predetermined intensity, there is a risk that the X-ray generator is overheated as well as power consumption, thereby shortening the life of the X-ray generator.

On the other hand, when an X-ray leaks, it has a detrimental effect on the human body. Therefore, it is not preferable from an environmental viewpoint to project an X-ray for a long time.

Therefore, it is urgently required to provide a method of projecting X-rays to the cleaning solvent of the dry cleaning apparatus in a more environmentally friendly manner.

Will be described with reference to Figs. 1 and 2. Fig.

The volatile cleaning solvent recovery and washing module 10 according to an embodiment of the present invention includes a configuration for cleaning the laundry 75 with a volatile cleaning solvent that is volatile organic compounds (VOCs), a configuration for drying the cleaned laundry 75 And a configuration for recovering the volatile cleaning solvent vaporized during the drying of the laundry 75 and contained in the air.

The washing module 10 includes a housing 11, a drum 20, a hot wind generator 33, an anti-static unit 41, a boiler 46, an air filter 47, (50), an oil water separator (60), a cleaning solvent tank (67), and a drain tank (69).

The drum 20, the hot air generator 33, the static electricity preventer 41, the air filter 47, the condenser 50, the oil water separator 60, the cleaning solvent tank 67, and the drain tank 69, Is provided in the housing (11).

The housing 11 is formed with a door 15 that can be opened and closed on the front surface thereof. The door 15 is pivotably coupled to a panel on the front surface of the housing 11 by a hinge (not shown). The drum 20 is disposed inside the housing 11 so as to be rotatable about a rotation center axis RL parallel to the X axis. A drum opening (opening) 21 is formed in the front surface of the drum 20 so as to allow the laundry 75 to be inserted and discharged.

The drum opening 21 is formed in a position aligned with the door 15 along the rotation center axis RL. Therefore, when the door 15 is opened and the laundry 75 is poured into the housing 11, the laundry 75 is accumulated in the drum 20. Also, the laundry (75) accumulated in the drum (20) can be taken out of the housing (11) by opening the door (15).

On the outer peripheral surface of the drum 24, a plurality of through holes 23 are formed to allow liquid and gas to flow in and out. The inner diameter of the through hole 23 is designed to be small so that the laundry 75 is not discharged through the through hole 23. Although not shown in FIG. 1, the washing module 10 includes a drum rotation motor for providing power for rotating the drum 20 to the rear of the housing 11, and a rotary motor for rotating the drum 20, To the power transmission unit.

The hot air generator 33 heats the air to form hot air HA flowing into the drum 20 and is positioned on the upper side of the drum 20 in the housing 11. The hot air generator 33 includes a hot air generator core 34, a heat medium supply pipe 38 for guiding the path of the heat medium HM to supply the heat medium HM to the core 34, And a heat medium discharge pipe 39 for guiding the path of the heat medium HM discharged from the core 34. [

The core 34 defines a flow path of the thermal medium HM supplied by the thermal medium supply pipe 38 and includes a heat medium micro tube 35 extending along a zigzag path, And a fin 37 attached to the outer peripheral surface of the thermal medium micro tube 35 to promote heat exchange. The fin 37 may be a corrugated fin that is corrugated to increase the contact surface area with the wave-like air. The heat medium microtubes 35 are connected to the heat medium supply pipe 38 and the heat medium discharge pipe 39 so as to allow the flow of the heat medium HM.

The heat of the thermal medium micro tube 35 is transferred to the fin 37 through the heat conduction and the heat is transferred to the air flowing through the fin 37 to heat the air to form the hot air HA. The washing module 10 further includes a blower 31 for pressurizing the air so that the air flows in parallel with the positive (+) direction of the X axis and passes through the hot air generator core 34.

The thermal medium (HM) is water (H2O). Specifically, the heat medium HM supplied to the core 34 along the heat medium supply pipe 38 is steam, which is gaseous water. Water that has been liquefied through heat dissipation in the core 34 or gaseous steam in a gaseous state whose temperature is lower than that when it is introduced into the core 34 is discharged through the heat medium discharge pipe 39 as the heat medium HM And is discharged from the core 34. The boiler 46 boils water in the liquid state to form water vapor, which is supplied to the core 34 through the heat medium supply pipe 38. The boiler 46 is also connected to the heat medium discharge pipe 39 so that the heat medium HM discharged through the core 34 is introduced into the boiler 46 through the heat medium discharge pipe 39 and heated again.

The electrostatic preventer 41 is located behind the hot air generator 33 along the path of the hot air HA and passes steam VA through the hot air generator 33 to the hot air HA directed to the drum 20. [ Spray. The static electricity prevention device 41 includes a steam supply pipe 42 connected to the heat medium supply pipe 38 in a fluid-flowable manner, a steam injection nozzle 45 provided at the end of the steam supply pipe 42, And a control valve 43 for controlling the flow rate of the water vapor VA through the evaporator 42.

As the drying process is performed through the supply of hot air (HA), the inside of the drum 20 is gradually lowered in humidity, the temperature is raised, and an environment in which static electricity is easily generated is formed. At this time, the steam VA blown to the hot air HA through the steam injection nozzle 45 increases the humidity of the hot air HA flowing into the drum 20. [ Since the humid hot air HA flows into the drum 20, the humidity inside the drum 20 also increases, thereby reducing the risk of explosion and fire accidents. The control valve 43 is automatically operated in conjunction with the progress of the drying process or the humidity inside the drum 20 to automatically adjust the amount of water vapor VA and the spray timing through the steam spray nozzle 45.

The hot air HA having passed through the hot air generator 33 and the static electricity prevention device 41 flows into the drum 20 along the hot air guide passage 28 inside the housing 11. [ The inclined face 17 provided on the door 15 guides the hot air HA discharged from the hot air guide passage 28 into the drum 20 through the drum opening 21. [ Specifically, the inclined surface 17 is defined by an outer peripheral surface of a tapered door 15 whose diameter becomes smaller toward the rear in parallel with the direction of the negative X-axis (-). When the door 15 is closed, the rear end portion of the inclined surface 17 extends to a position further rearward than the position of the drum opening 21. 1, the hot air HA discharged from the hot air guide passage 28 is guided obliquely rearward by the inclined surface 17 and is mostly introduced into the drum 20 through the drum opening 21 .

The drum 20 is rotated by the operation of the washing module 10 so that the laundry 75 in the drum 20 is caught on the outer circumferential surface of the drum 20 and then dropped by the gravity to rotate the drum 20 The laundry 75 which has moved toward the rotation center RL of the drum 20 is caught by the hot air HA discharged from the inclined surface 17 at the moment of moving toward the center RL side, The drying efficiency is improved, the time required for drying the laundry 75 is shortened, and the energy consumption is also reduced.

(DA) in which volatile washing solvent evaporated in the laundry 75 in the drying process, impurities such as steam, dust, and the hot air HA introduced into the drum 20 are mixed, And is discharged to the outside of the drum 20 through the drum through hole 23 and flows toward the rear of the drum 20 along the exhaust gas guiding flow passage 26 inside the housing 11. [ The air filter 47 is disposed inside the housing 11 at the rear of the drum 20 and filters the impurities from the exhaust gas DA discharged from the drum 20 and directed to the condenser 50. The air filter 47 is provided with a plurality of filters 48 arranged so as to overlap with one another or along the flow path of the exhaust gas DA.

The condenser 50 is disposed in the housing 11 below the hot air generator 33 and above the air filter 47 and cools the exhaust gas DA to cool the liquid LQ from the exhaust gas DA Separate and extract. The liquid LQ extracted through the condenser 50 contains the liquefied volatile cleaning solvent CL and the liquid water. The condenser 50 includes a condenser core 51 for cooling the exhaust gas DA that has passed through the air filter 47, a liquid receiver 55, and a liquid shutoff member 57.

The condenser core 51 has a coolant microtubule 52 extending along a zigzag path so that the coolant gas flows, similar to the hot air generator core 34 (see FIG. 2). The exhaust gas DA passes around the coolant microtubule 52 and is cooled through heat exchange so that the volatile cleaning solvent and water contained in the exhaust gas DA are liquefied and formed on the outer circumferential surface of the refrigerant microtubule 52 .

The receiving plate 55 is a member in the form of a funnel positioned at a position lower than the condenser core 51 directly behind the condenser core 51 along the flow path of the exhaust gas DA. The liquid LQ formed on the outer circumferential surface of the coolant microtubule 52 is lowered and flows down to the liquid receiver 55. [

The liquid blocking member 57 is a member having an inclined surface extending obliquely and is located on the upper side of the liquid receiver 55 to partially obstruct the flow of the exhaust gas DA passing through the condenser core 51, . The liquid blocking member 57 is configured such that the liquid LQ collected on the outer circumferential surface of the condenser core 51 or the liquid LQ collected on the liquid receiver 55 passes through the condenser core 51 and flows to the hot air generator 33 (DA), and is prevented from flowing into the hot air generator (33). The liquid LQ is not mixed into the air directed to the hot air generator 33 side or the exhaust gas DA due to the liquid blocking member 57 and does not flow into the hot air generator 33. Therefore, The required energy can be saved and the drying failure of the laundry 75 which may occur due to the temperature of the hot air HA being lower than the proper temperature is prevented and the durability of the hot air generator 33 is improved.

The oil water separator 60 is located inside the housing 11 at the lower rear side of the drum 20 and is connected to the liquid receiver 55 by the liquid flow path 65. The liquid LQ collected in the liquid receiver 55 flows into the oil water separator 60 through the liquid channel 65. The oil water separator 60 separates the volatile washing solvent CL as the organic compound from the water WA (CL) and water (WA) are separated from each other without mixing.

The cleaning solvent tank 67 is a tank in which the volatile cleaning solvent CL necessary for cleaning in the dry cleaning type is accommodated and is located below the drum 20 in the housing 11. [ The volatile cleaning solvent CL separated from the water WA in the oil water separator 60 flows into the cleaning solvent tank 67 and merges with the volatile cleaning solvent CL already contained in the cleaning solvent tank 67 .

The drainage tank 69 is located inside the housing 11 at the lower side of the drum 20 and the water WA separated from the volatile cleaning solvent CL is received and accommodated in the oil water separator 60. If the water WA is collected in the drain tank 69, the operator of the cleaning module 10 drains the water WA through the sewer pipe. The drainage tank 69 may not be provided in the washing module 10. In this case, the water WA separated from the volatile washing solvent CL in the oil water separator 60 is not stored, Drainage.

The operator can wash the laundry 75 that has been introduced into the drum 20 by using the washing module 10. The liquid volatile cleaning solvent CL contained in the cleaning solvent tank 67 is circulated between the cleaning solvent tank 67 and the drum 20 in the course of washing the laundry 75. [ The volatile cleaning solvent CL flows into the drum 20 into which the laundry 75 is charged and flows along the cleaning solvent supply path so that about half of the inner space of the drum 20 is filled with the volatile cleaning solvent CL), the drum 20 rotates about the rotation center axis RL, and the laundry 75 is cleaned. The volatile cleaning agent CL is discharged from the drum 20 and flows into the cleaning solvent tank 67 along the cleaning solvent discharge path (not shown), and the drum 20 is rotated at a high speed The volatile cleaning solvent CL dewatered in the laundry 75 is also flowed back into the cleaning solvent tank 67 along the cleaning solvent discharge path.

The volatile cleaning solvent recovery and washing module 10 is integrally formed with a structure for cleaning the laundry 75, a structure for drying the laundry 75, and a structure for recovering the volatile cleaning solvent, Installation is possible in this limited space. If the spread of the washing module 10 is spread due to such advantages, the air pollution and odor due to the flow of VOCs are improved and the risk of cancer is reduced.

The washing module 10 is provided with a circulation path through which air is supplied to the hot air generator 33 through the hot air generator 33, the static electricity preventer 41, the drum 20, the air filter 47 and the condenser 50 The laundry 75 contained in the drum 20 is circulated in the housing 11 so that the volatile cleaning solvent does not flow out of the housing 11 and the recovery rate of the volatile cleaning solvent is improved.

The washing module 10 includes an electrostatic protector 41 so that the generation of static electricity is suppressed in the drum 20 when the laundry 75 washed by the dry cleaning method is dried to reduce the risk of fire or explosion .

FIG. 3 is a view for explaining an operation of automatically controlling an X-ray generator according to the present invention, and FIG. 4 is a sectional view showing an X-ray generator according to the present invention

Will be described with reference to Figs. 3 and 4. Fig.

The X-ray generator 100 is installed inside the cleaning solvent tank 67 by projecting the X-ray into the cleaning solvent tank 67.

In the present invention, a controller (not shown) for controlling the X-ray generator 100 is provided. The controller variably controls the frequency, intensity, and direction of the X-ray projected from the X-ray generator 100.

A contamination level sensor is provided to measure the level of contamination of the cleaning solvent.

The pollution level sensor is disposed inside the cleaning solvent tank 67 to measure the degree of contamination of the cleaning solvent.

When the X-ray generator 100 projects the X-ray for a long time, the X-ray generator 100 may overheat and shorten its service life. In addition, even when the sterilization operation for the cleaning solvent is sufficiently performed, the X-rays are continuously projected, thereby increasing the probability that the X-rays leak unnecessarily.

Accordingly, the present invention solves this problem by using a pollution degree sensor and a controller.

In the controller, set the reference value of pollution degree which requires projection of X-rays in advance. The controller transmits an x-ray generation signal to the x-ray generator 100 only when the degree of contamination measured by the pollution level sensor exceeds a predetermined reference value, so that the x-ray is projected only when necessary.

On the other hand, the intensity of the x-ray is controlled not only by the frequency of the x-ray but also by the degree of the contamination degree. If the contamination is severe, the intensity of the X-ray is raised and projected. If the contamination is slight, the intensity of the X-ray is projected low.

A variety of sensors can be employed for the pollution level sensor.

As the pollution level sensor, a gas sensor can be adopted. The gas sensor senses the gas emitted by aerobic bacteria and measures its concentration.

On the other hand, the optical sensor 300 can be adopted as the pollution degree sensor.

The light sensor 300 includes a light emitting portion 310 and a light receiving portion 320.

The light emitting unit 310 is installed on one side of the cleaning solvent tank 67 and scans the cleaning solvent with light of a reference light amount.

The light receiving unit 320 is installed on the other side of the cleaning solvent tank 67 and detects the light emitted by the light emitting unit 310.

As the contamination increases, the cleaning solvent becomes turbid and the amount of light detected by the light receiving unit 320 decreases. Accordingly, when the amount of light sensed by the light receiving unit 320 is equal to or less than a predetermined reference value, the controller transmits an X-ray generation signal to the X-ray generator 100.

A plurality of X-ray generators 100 must be installed in order to sufficiently project the X-rays to the entire area of the cleaning solvent tank 67.

In order to sufficiently project an X-ray to the entire area of the cleaning solvent tank 67 with one X-ray generator 100, the X-ray generator 100 is rotated in the present invention.

For this purpose, a rotation motor 200 and a support plate 220 are provided.

The rotation motor 200 is coupled to one side of the interior of the cleaning solvent tank 67. The rotation motor 200 is capable of forward rotation and reverse rotation, and repeats the reciprocating rotation motion.

The support plate 220 is coupled to the rotation shaft 210 of the rotation motor 200 and rotates together. A light emitting portion 310 is disposed on the upper surface of the support plate 220.

The X-ray generator 100 is disposed on the upper surface of the support plate 220 adjacent to the light emitting unit 310.

The light receiving unit 320 is installed at the other side of the cleaning solvent tank 67 at the same height as the light emitting unit 310 and spaced apart from each other by a predetermined distance so as to sense light in various directions.

When the light emitting unit 310 rotates and scans light, a plurality of light receiving units 320 installed on the other side of the cleaning solvent tank 67 detects light.

When the amount of light sensed by the light receiving unit 320 is less than a predetermined value, the control unit transmits the X-ray generation signal to the X-ray generator 100. As a result, the X-ray generator 100 adjacent to the light emitting unit 310 scans the X-ray in the direction of the light-receiving unit 320 detected to be highly contaminated.

The X-ray generator 100 can be used to scan the X-ray to the cleaning solvent in the direction of high contamination.

An X-ray shielding film may be formed on the inner surface of the cleaning solvent tank 67. When the X-ray projected by the X-ray generator 100 is projected to the outside of the dry cleaning apparatus, the safety and health may be caused. Therefore, the X-ray shielding film is formed on the inner surface of the cleaning solvent tank 67 so that the X-ray can not pass through the cleaning solvent tank 67.

The X-ray shielding film may be made of a metal having excellent shielding performance against radiation such as X-rays. Examples of the metal having excellent radiation shielding performance include lead (Pb), barium (Ba), and iron (Fe), and at least one of these metals may be included as a material.

X-ray generator 100 includes a vacuum tube 101, a cathode 102, an anode 103, a rotating shaft 104, a shaft support 105, a bearing 106, A rotor 107, a stator 108, and a stator 108.

The vacuum tube 101 is similar to a bell in appearance, and is called a so-called bellcan. The vacuum tube 101 has a large diameter portion 109 having a relatively large diameter and a small diameter portion 110 having a smaller diameter than the large diameter portion 109 and connected to the large diameter portion 109 and disposed below the large diameter portion 109, Respectively. The vacuum tube 101 is sealed, and the inner space of the vacuum tube 101 is maintained in a high vacuum state.

The cathode 102 is fixed on the upper side of the vacuum tube 101 and forms a potential difference of about 150 V (volt) with the anode 103. The electrons E generated in the cathode 102 are accelerated by the potential difference and projected onto the anode 103. Since the electrons E are projected and collided with the anode 103, the anode 103 is also referred to as an X-ray tube target.

The anode 103 is a member in the form of a disk and includes a base layer 111 composed of a molybdenum alloy containing molybdenum or molybdenum as a main material, And an electron collision layer 112 in which a metal including tungsten (W), that is, a tungsten alloy containing pure tungsten (W) or tungsten as a main material, is laminated on the outer peripheral portion of the upper surface of the upper substrate 111. The electron beam collided with the electrons collided with the electron collision layer 112 at the cathode 102 causes the X-ray to be emitted. 4, the anode 103 may further include a heat-radiating layer made of graphite or a C-C composite (carbon-carbon composite) under the base layer 111 for promoting heat radiation.

The rotary shaft 104 supports the anode 103 in the vacuum tube 101 to rotate around the rotation center axis RL and includes an upwardly extending upper shaft portion 113 and a downwardly extending lower shaft portion 113. [ And a flange portion 115 extending radially so as to have a larger diameter between the upper shaft portion 113 and the lower shaft portion 114. The upper shaft portion 113 is fitted in a through hole (not shown) passing through the center of the anode 103 in the up and down direction and tightened by the fixed cap 116 (cap) and fixedly coupled to the anode 103.

The shaft support 105 is fixedly coupled to the lower end of the vacuum tube 101 so that the lower end of the vacuum tube 101 is sealed and the lower shaft portion 114 is coupled to the shaft support 105 along a rotation axis RC. As shown in FIG. The upper and lower bearings 106 are interposed between the lower shaft portion 114 of the rotary shaft 104 and the shaft support 105 to rotate the rotary shaft 104 and the anode 103 fixed thereto by a rotation axis RC) at a high rotation speed.

The upper end of a tube-shaped rotor 107 disposed inside the small diameter portion 110 of the vacuum tube 101 is fixedly coupled to the flange portion 115 of the rotating shaft 104. The stator 108 has a coil (not shown) that is wound to surround the rotor 107 outside the small diameter portion 110 of the vacuum tube 101. When an electric current is applied to the coil, an electromagnetic force is generated and the rotor 107 and the rotating shaft 104 and the anode 103 fixedly coupled to the rotor 107 rotate at a high speed with respect to the rotation axis RC.

The electrons E projected from the cathode 102 collide with the electron collision layer 112 of the anode 103, and the X-rays X are emitted at this time. The X-ray generator 100 is configured to rotate the anode 103 at a high speed to increase the amount of X-ray X emitted when the electrons E collide with the anode 103, and is called a positive rotation X-ray tube.

X-ray (X) has shorter wavelength than ultraviolet rays and has higher energy, so it has better permeability to substances and has higher killing power to cells. Therefore, the sterilizing power to kill the bacteria contained in the cleaning solvent is excellent.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
