Description

{A Sterilizer for clothes}

The present invention relates to a fabric sterilizing apparatus, more particularly, to a fabric sterilizing apparatus that sterilizes both front and back surfaces of a fabric by irradiating ultraviolet rays automatically when the fabric is placed in the sterilizing apparatus, The present invention relates to a fabric sterilizing apparatus capable of being shaken from a fabric.

It is widely known that ultraviolet light has a sterilizing effect. In view of this point, conventionally, a sterilizing apparatus using an ultraviolet lamp has been widely used.

Most of them put the objects in a certain space and turned on the ultraviolet lamp to sterilize the surface of the object receiving the ultraviolet rays. For example, a conventional sterilizer for dishes, a comb sterilizer in public baths, and the like, are provided with a conventional ultraviolet lamp in a certain space, a wall surface constituting the space is formed as a reflective surface, It was a way to put the object on and turn on the lamp for a certain period of time to sterilize the object inside.

Also, clothes are one of the most demanding things around us. Clothes come into direct contact with the skin, so if you wear clothes with many harmful bacteria, it can cause skin troubles. Especially, clothes of young children with weak immunity should be thoroughly sterilized.

However, when the clothes are sterilized by boiling or the like, the fiber is deformed due to the high temperature environment, and the cloth is damaged or damaged, so it is not easy to sterilize the clothes. However, clothes that can be sterilized by using a sterilizing detergent are extremely limited in type due to problems such as discoloration. Above all, this kind of sterilization method can be applied to clothes that can be washed with water. Therefore, there is a need for a method capable of sterilizing while not damaging the cloth.

Ultraviolet sterilization is the most suitable disinfection method for this kind of cloth sterilization.

Conventional conventional ultraviolet lamps such as mercury lamps, excimer lamps, and deuterium lamps all have high power consumption and heat generation, short life spans, and toxic gases There is a problem that the environment is contaminated.

On the other hand, UV LED has the advantage of low power consumption and no problem of environmental pollution. However, the manufacturing cost of an LED package that emits light in the UV region is considerably higher than the manufacturing cost of an LED package that emits light in visible light, and a variety of applications using an LED package can not be developed due to the characteristics of UV light.

The most important feature to be considered when sterilizing with ultraviolet rays is that, unlike the method of high temperature sterilization, sterilization is mainly performed on the surface irradiated with ultraviolet rays, and sterilization and disinfection are not performed well on areas where ultraviolet rays are not irradiated.

Therefore, it can not be said that sterilization of the cloth is done properly by simply putting the cloth roughly and irradiating the ultraviolet rays. That is, a structure capable of irradiating ultraviolet light uniformly over all areas is required without overlapping the cloth.

In addition, in the case of cloth, there is a need to remove dust and house dust mites. Therefore, it is necessary to add these functions in addition to the structure capable of irradiating ultraviolet rays evenly on all areas,

Disclosure of the Invention The present invention has been conceived in order to solve the problems described above, and it is an object of the present invention to provide a simple structure capable of sterilizing a fabric without missing areas by uniformly irradiating ultraviolet rays on both sides of the fabric, And to provide a fabric sterilizer.

In order to achieve the above object, according to the present invention,

The UVLED module 30 is installed in the lifting device 35 in the closed space and is movable up and down.

And a sensor (4) for checking the length of the fabric hung on the pair of clothes hanger rods (21, 22).

The sensor is installed at an intermediate height portion of the closed space,

The sensor confirms whether or not the fabric fixed to the upper ends of the clothes hook rods 21 and 22 is stretched to a middle height portion of the closed space.

The sensor is a water light emission sensor which is arranged in a closed space in a vertical direction, and the length of the fabric in the vertical direction is determined by the number of the water light emission sensor sensing the fabric.

The sensor is a water light emission sensor which is disposed in a closed space in a plurality of left and right directions, and the width of the fabric in the left and right direction is determined by the number of the water light emission sensor sensing the fabric.

Fans 51 and 52 are installed on the bottom surface 17 of the closed space, and the fans 51 and 52 suck air in the closed space and discharge the air into the ducts 61 and 62. The nozzle portions of the ducts Are installed so as to face the clothes hanging on the clothes hook use rods (21, 22).

A filter 70 is installed in the air suction units 511 and 521 of the fans 51 and 52.

The present invention also provides a method of sterilizing a fabric using the sterilizer described above,

Fixing both ends of the fabric to the pair of washer hanger rods (21, 22);

In the state where the pair of washer loaders 21 and 22 are positioned at the upper end, it is checked by the sensor 4 whether or not the fabric hung on the laundry loader rod is laid down below the middle height of the closed space step; And

When one of the pair of clothes hooking rods is lowered so that the fabric is unfolded by the two clothes hanger rods and irradiates the ultraviolet rays,

When the fabric is laid to below the middle height of the closed space, ultraviolet rays are irradiated in a state where the pair of washer-load rods are located on the upper side, and a center rod 23 And lowering the pair of clothes hook rods to irradiate the ultraviolet rays while inverting the fabric.

The method includes the steps of: confirming the vertical range of the fabric unfolded by the rod with the sensor 4; and moving the UVLED module 30 up and down within a range corresponding to the vertical range of the fabric, Further comprising the steps of:

FIGS. 7 and 8 show an embodiment of a method of sterilizing a fabric sterilizer according to the present invention, and FIGS.
9 to 11 are views showing still another embodiment of the sterilizing method of the fabric sterilizer according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

1 is a cross-sectional view taken along line bb of Fig. 1, Fig. 4 is a sectional view of cc of Fig. 2, Fig. 5 is a sectional view of dd of Fig. 1 is a view showing an embodiment of a laundry hanger load of the present invention.

1, the fabric sterilizer 1 of the present invention has a structure in which the upper surface 11 of the main body including the long side surface 13, the short side surface 15, and the bottom surface 17 can be opened and closed. That is, when the top surface 11 is opened, the inside of the fabric sterilizer 1 can be accessed. When the top surface 11 is closed, the inside of the fabric sterilizer is sealed against the outside space.

[road]

2 to 5, three rows of elevating devices 25 are provided in the vertical direction at the center of the short side 15 of the closed space in the fabric sterilizer 1. [

The lifting device 25 is provided with a pair of clothes hook rods 21 and 22 and a center rod 23 located between the two rods 21 and 22, respectively. The three rods (21, 22, 23) are independently controlled to move up and down. Particularly, a pair of the clothes hooking rods 21 and 22 are detachably attached to the elevating device 25. [

The pair of washer lifting rods 21 and 22 can be of a shape in which two long semicircular rods are separated into semicircles as shown in Fig. 11, and a method of sandwiching the fabric between these semicircular rods To fix the fabric. Thus, if both ends of the fabric are sandwiched between the clothes hanging rods as shown in FIG. 6, both ends of the fabric can be held to some extent by the rods 21 and 22. The clamping force can utilize a magnet (not shown) or a clip (not shown) for clamping both ends.

Since the pair of clothes hook rods are detachable with respect to the elevating device, the user separates the rods 21 and 22 from the elevating device to fix both ends of the fabric, and then the rods 21 and 22 are mounted on the elevating device The fabric can be mounted in a fabric sterilizer (see FIG. 7 or 9).

[UVLED module]

Next, two pairs of elevating devices 35 are provided at the four corners where the long side face 13 and the short side face 15 meet. The two pairs of lifting devices 35 operate in pairs in a direction parallel to the long side.

In the vicinity of the inner surfaces of both long side surfaces 13, a bar-shaped UVLED module 30 extending in the left and right longitudinal direction is disposed in the elevating device 35 so as to be long in the left and right direction as shown in the drawing .

Both ends of the UVLED module 30 are fixed to a pair of elevating devices. Since the pair of elevating devices operate together, the UVLED module 30 is vertically moved up and down according to the operation of the elevating device.

The two pairs of elevating devices 35 may be interlocked with each other or may operate independently of each other.

A plurality of UVLEDs 32 are arranged side by side in the longitudinal direction (see FIG. 3) on one side of the bar-shaped UVLED module 30, and they are arranged in a direction of irradiating ultraviolet rays toward the intermediate fabric 2).

The UVLED module 30 is detachably installed in the elevating device, and has a battery itself, so that the user can separate the UVLED module 30 and manually operate the UVLED module 30 if necessary. For example, if the user disconnects the UVLED module 30 and operates the switch, the UVLED is turned on, and ultraviolet rays are irradiated in one direction of the module. Therefore, if the user operates the bedding and slowly stroking the bedding, It is possible. Therefore, in the case of a large fabric which can not be inserted into the fabric sterilizer, the UVLED module 30 can be separated and sterilized.

As will be described later, the UVLED module 30 of the present invention moves in the sterilizer as it scans up and down, and irradiates ultraviolet rays on the fabric.

It is preferable that the UVLED has a peak wavelength of 275 nm to increase the sterilizing efficiency. In particular, UVLED has a characteristic that the spectrum is focused at a peak wavelength range as compared with a conventional light source lamp, and ultraviolet rays having a strong sterilizing power can be irradiated with much less power.

In addition, the UVLED is more suitable for the purpose and purpose of the present invention than a conventional ultraviolet lamp in which ultraviolet rays are irradiated in all directions unnecessarily since a point light source irradiating in one direction can be diffused to about 120 degrees.

In the present invention, it is preferable to treat all the inner surfaces of the closed space with an ultraviolet reflector in order to increase sterilization efficiency.

[sensor]

Next, the fabric sterilizer of the present invention is equipped with a sensor (40). As shown in Figs. 2 and 3, a plurality of sensors 40 are provided at regular intervals in the vertical direction of the sterilizer, and a plurality of sensors 40 are also provided at left and right sides of the sterilizer.

The sensor 40 may be a light emitting sensor and a light receiving sensor provided at positions corresponding to each other on the two opposite side surfaces 13. For example, if an object is placed between the pair of light-receiving sensors and the light-emitting sensor, and the light of the light-emitting sensor does not reach the light-receiving sensor facing the light-receiving sensor, it can be determined that something is placed at the corresponding position.

Therefore, when the plurality of sensors 40 are installed at regular intervals in the vertical direction of the sterilizer as shown in the drawing, the length and position of the fabric in the vertical direction can be determined according to the position and number of the sensors to be covered, The length and position of the fabric in the width direction can be determined by the same principle.

2 and 3, it can be seen that the sensor 40 is located at the middle portion in the height direction (see the dotted line in FIG. 2) in the present invention. The sensor at this position is more meaningful than the sensor at the other position. If the sensor of the middle height does not detect the fabric while the two rods 21, 22 fixing both ends of the fabric are located at the top of the fabric sterilizer, (See FIG. 7 to be described later), and the two rods 21 and 22, which are fixed at both ends of the fabric, are positioned at the top of the fabric sterilizer, If the height sensor senses the fabric, it can be determined that the overall length of the fabric in the up-and-down direction is longer than the overall height of the interior space of the fabric sterilizer (see FIG.

[Fans and ducts]

As shown in FIGS. 2 to 4, the fabric sterilizer of the present invention is provided with two fans 51 and 52 in the inner space of the bottom surface 17, and the air suction units 511 and 521 of the fan And the air discharge portions 512 and 512 of the fan communicate with each other through the ducts 61 and 62 from the two side surfaces 13 toward the inner space of the fabric sterilizer. A filter (70) is provided in the air suction portion of the fan.

Accordingly, when the fan operates, the air in the inner space of the cloth sterilizer flows into the fans 51 and 52 through the air suction units 511 and 521, forcibly flows along the ducts 61 and 62, ), And this circulation continues while the fan is turned on.

The strongly discharged air hits the hanging fabric and drops the foreign matter in the fabric, which is filtered by the filter 70 on the bottom surface. Needless to say, the filter 70 is detachably installed so that it can be cleaned or replaced.

The fan can operate at the same time as sterilizing the fabric with ultraviolet light, operating after sterilizing the fabric, or operating separately from sterilization of the fabric.

[Operation of the fabric sterilizer]

Hereinafter, the operation of the fabric sterilizer of the present invention having the above-described configuration will be described.

FIGS. 7 and 8 are views showing an embodiment of a method of sterilizing a fabric sterilizer according to the present invention, and FIGS. 9 to 11 are views showing still another embodiment of a sterilizing method of a fabric sterilizer according to the present invention.

When the fabric is shorter than the vertical height of the inner space of the fabric sterilizer, both ends of the fabric are sandwiched between the clothes hanging rods 21 and 22 as shown in Fig. 7 and placed on top of the lifting device 25 Even if the lower end of the fabric C is not lower than the half height, it does not fall. Thus, the sensor 4 at the center height portion senses that there is no fabric at the corresponding height position.

When the sensor 4 at the center height detects that there is no fabric at the height, the fabric sterilizer of the present invention descends the one side rod 21 as shown in Fig. 8, .

In this state, when it is sensed that the range in which the fabric is spread with a plurality of vertically arranged sensors is in the range h of FIG. 8, the control unit (not shown) operates the elevating device 35 to operate the pair of UVLED modules 30 ) Is controlled to move slowly up and down within the range of h.

Therefore, the fabric is sterilized by ultraviolet rays irradiated by UVLED, and the front and back sides are uniformly irradiated with ultraviolet rays.

The above-described fan can operate with this operation, or after completion of such operation, to shake the foreign object (dust or house dust mites) of the fabric.

When the fabric is longer than the vertical direction height of the inner space of the fabric sterilizer, both ends of the fabric are sandwiched between the clothes hanging rods 21 and 22 as shown in FIG. 9 and positioned at the upper end of the lifting device 25 The lower end of the fabric C which is stretched is lower than the half height. Thus, the sensor 4 at the central height portion senses that there is fabric at the corresponding height position.

When the sensor 4 at the center height detects that there is a fabric at the corresponding height, the fabric sterilizer of the present invention firstly has two rods 21 and 22 at the top as shown in FIG. 10, And the position of the fabric is detected by the sensors disposed in the open position. When the sensor detects that the range of the fabric is within the range of h in FIG. 10, the control unit (not shown) operates the elevating device 35 to move the pair of UVLED modules 30 slowly up and down within the range of h Respectively.

Therefore, the fabric is irradiated with ultraviolet rays irradiated by UVLED, and firstly the surface is uniformly sterilized by receiving ultraviolet rays.

11, the center rod 23 is moved to the upper end, the two rods 21 and 22 are lowered to invert the fabric C, and a plurality of vertically arranged Sensors are used to determine the position of the fabric. 11, the control unit (not shown) activates the lifting device 35 so that the pair of UVLED modules 30 move slowly up and down within the range of h Respectively.

Of course, in this case it is possible to omit the operation of detecting the range of the fabric with the sensor. 10, the two rods 21 and 22 are at the top, and if the center rod 23 is at the top even in the state after the inversion as shown in FIG. 11, Since there is substantially no difference in position, it is not necessary to search the upper and lower ranges of the fabric again with the fabric inverted as in Figure 11

Likewise, the above-described fan can operate with this operation, or after completion of such operation, to shake the foreign object (dust or house dust mites) of the fabric.

According to the present invention, since a plurality of sensors 4 are provided in the lateral direction, it is also possible to detect the width of the fabric.

In the case of detecting the width of the fabric, only UVLEDs 32 of the UVLEDs corresponding to the width of the fabric among the UVLEDs installed over the entire length of the UVLED module can be controlled to emit ultraviolet rays to the fabric, It can be operated efficiently.

As described above, in the present invention, since the fabric is spread vertically and flatly at the central portion of the sterilizer by the rod, the sterilizer can be made slim. The short side 15 of the sterilizer can be made even thinner.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that it can be done. Although the embodiments of the present invention have been described in detail above, the present invention is not limited to these embodiments.
