There are quite a few items in our daily life that require attention to sterilization and drying management. For example, in the case of clothes or shoes, if sterilization, deodorization, and drying are not properly performed after use, bacteria multiply, and in particular, shoes start to generate bad odors. In addition, toothbrushes, tableware, baby bottles, etc. must be thoroughly sterilized and dried after use.

There are various types of conventional sterilization and drying devices. For example, there is a device that blows dry hot air to an object to remove moisture and at the same time sterilizes and deodorizes with an ultraviolet lamp and an ozone generator.

As a background technology for this related invention, Korean Patent Registration No. 10-1500610 (Sterilization, Deodorization, Air Flow System for Drying Device) has been disclosed.

A main body each provided with a plurality of doors for opening and closing; a blowing system installed on the upper part of the main body to sterilize, deodorize, and dry the air, and forcibly supply air to each storage room; In the air passage system of a sterilization and deodorization drying apparatus composed of an air passage system having an air supply passage connected to a ventilation system to supply air to each storage room and an exhaust passage to return contaminated air from each storage room to the ventilation system, A branch duct communicating with the air supply opening of the system is installed horizontally, and an air supply duct with branch holes formed at equal intervals at both ends of the branch duct is installed vertically, and the branch holes of the two air supply ducts facing each other communicate with the storage rooms on both sides an air supply passage equipped with a horizontal duct; A square tube-shaped vertical exhaust duct is installed vertically between each storage room on both sides, and an exhaust port communicating with each storage room is formed on both sides of the vertical exhaust duct. are installed, respectively, and the upper end of the vertical exhaust duct has a structure including an exhaust passage communicating with the exhaust port of the blowing system.

However, in the air passage system described above, since each storage room is connected to a single flow path, it is impossible to selectively use the storage room. That is, the air blown by the blowing fan of the blowing system passes through all the storage rooms in order. Hygiene problems may arise because the air that has passed through a certain storage room also passes through other storage rooms. For example, when shoes are stored in the upstream storage room and baby bottles are stored in the downstream storage room, the baby bottles are not sterilized and dried, but may rather be contaminated with bacteria.

As shown, the multi-stage sterilization dryer 10 according to the present embodiment includes a blowing module 20, a plurality of unit sterilization and drying boxes 30, air induction means, and a controller (27 in FIG. 4).

The blowing module 20 purifies and dries air and supplies it, and the unit sterilization drying box 30 serves to provide a space for sterilization and drying of objects to be sterilized and dried (clothes, toothbrushes, shoes, baby bottles, etc.) do. In addition, the air induction means guides the air of the blowing module to the selected unit sterilization drying box 30. Control of the air induction means is performed by the controller (27).

The blowing module 20 includes a casing 21, a blower 23, a purification processing unit, a dryer 24, a sterilizer 26, and a distribution tank 21g.

The casing 21 takes the shape of a box and serves as a support for supporting the unit sterilization drying box 30 having a multi-stage structure. In addition, an inspection cover 21a is provided on one side of the casing 21 . When the inspection cover 21a is separated, the inside of the casing is opened, and maintenance of internal components is possible.

The purification processing unit is a filter unit 22 that filters air introduced through the inlet pipe 21d. As long as air is filtered, the configuration of the filter unit 22 can be varied. If necessary, the filter unit 22 may be disposed on the downstream side of the blower 23.

The blower 23 is an air pump that pumps air that has passed through the filter unit 22 . The air can be pumped by the blower 23 and come down after reaching the unit sterilization drying box 30 on the top floor.

Dryer 24 removes moisture from the air. A drying method of air can be implemented in various ways, and for example, a method of heating air can be applied. The sterilizer 26 sterilizes and removes bacteria that may be mixed in the dried air. The sterilization method of the sterilizer 26 can also be applied in various ways.

The air passing through the sterilizer 26 moves to the distribution tank 21g and then is supplied to the supply passage 31b provided in the unit sterilization and drying box 30 on the lowest floor or to the treatment space 31a. The flow direction of the air is determined by the inlet-side blocking flap (41a). That is, when the inlet-side blocking flap 41a is rotated in the direction of arrow a in FIG. 4, air goes up to the supply passage 31b, and when rotated in the direction opposite to the direction of arrow a (direction b), it moves to the processing space 31a. is to do The driving of the inflow-side blocking flap (41a) is performed by the opening and closing driving unit (43). Also, the opening/closing driving unit 43 is controlled by the controller 27 .

The controller 27 is installed in the casing 21 and outputs all control signals related to the operation of the sterilization dryer 10. The controller 27 is wirelessly connectable with a user's smart phone. The user can remotely operate the controller 27 with his/her smartphone.

The unit sterilization drying box 30 takes the form of a hexahedral box and has a structure in which a plurality of pieces are vertically stacked. The applied number of the unit sterilization drying box 30 may vary depending on the embodiment, and may be composed of three layers, two layers, or four or more layers as shown in FIG.

The unit sterilization drying box 30 includes a cabinet 31 and a door 33.

The cabinet 31 provides a processing space 31a open to the front and is opened and closed by a door 33. The volume of the processing space 31a may vary depending on the type of object to be processed. For example, the processing space 31a of the unit sterilization and drying box for processing large-sized clothes is naturally larger in volume than the processing space 31a of the unit sterilization and drying box for processing toothbrushes.

In addition, inside the cabinet 31, a temperature controller 34 and a sterilizer 37 are installed. The temperature controller 34 controls the temperature inside the processing space 31a. For example, heat is generated when the internal temperature is lower than the set value, and air is cooled when the internal temperature is higher than the set value.

The sterilizer 37 additionally sterilizes bacteria inside the processing space 31a. For example, bacteria floating in the treatment space as well as bacteria attached to the object to be treated newly received in the treatment space 31a are sterilized. As the sterilizer 37, an ozone sterilizer or an ultraviolet sterilizer can be used. If necessary, a dryer may be additionally installed in the treatment space 31a.

A touch panel 35 and a wireless receiver 36 are disposed on the front of each cabinet 31 . The touch panel 35 is a user interface that not only controls the temperature controller 34 and the sterilizer 37 but also inputs temperature and humidity conditions inside the cabinet 31 . Each touch panel 35 is internally connected to the controller 27 . The operating conditions input through the touch panel 35 are transmitted to the controller 27, and the controller 27 adjusts and supplies air conditions according to the input temperature and humidity conditions.

The wireless receiver 36 is a signal receiver that receives a signal transmitted from a user's smart phone. Depending on the user's convenience, the user may directly touch the touch panel 35 to input desired content or input using a smart phone.

In addition, an inlet-side blocking flap 41a and an outlet-side blocking flap 41b are disposed on the bottom portion 31m of the cabinet 31a of the unit sterilization drying box 30.

In one embodiment, as shown in FIG. 4, the inflow blocking flap 41a may be located in the unit sterilization drying box 30 of the first and second floors, and the outflow blocking flap 41b may be located on the second and third floors. It can be installed in the unit sterilization drying box 30 of the layer.

That is, as shown in FIG. 4, in the unit sterilization and drying box 30 located on the uppermost layer, the inlet side blocking flap 41a is omitted, and in the unit sterilizing and drying box 30 located in the lowermost layer, the outlet side blocking flap 41b ), it is possible to configure a multi-stage sterilization dryer more simply by omitting.

The inlet-side blocking flap 41a is a door that opens and closes the inlet 31p, and the outlet-side blocking flap 41b is a door that opens and closes the outlet 31q. The inlet 31p is a passage leading air introduced from the blowing module 20 into the processing space 31a, and the outlet 31q is a passage through which air inside the processing space 31a is exhausted.

The inlet 31p and the outlet 31q are located on opposite sides. The air introduced upward through the inlet goes up to the ceiling of the treatment space 31a, then descends and exits through the outlet 31q.

The inflow-side blocking flap 41a includes a first inflow blocking plate 41a1, a second inflow blocking plate 41a2, and a third inflow blocking plate 41a3. The first, second, and third inflow blocking plates 41a1, 41a2, and 41a3 operate independently through their respective opening and closing actuators 43. In the case of the embodiment shown in FIG. 4, there are six inflow blocking plates of the sterilization dryer 10, and all the inflow blocking plates move independently.

The opening/closing driving unit 43 rotates the inflow-side blocking flap 41a in the direction of arrow a in FIG. 4 or in the opposite direction. When the inlet-side blocking flap 41a rotates upward, the inlet 31p is blocked and the supply passage 31b is opened. Conversely, when the inlet-side blocking flap 41a rotates downward, the inlet 31p is opened and the supply passage 31b is blocked.

The outflow-side blocking flap 41b has a first outflow blocking plate 41b1, a second outflow blocking plate 41b2, and a third outflow blocking plate 41b3. The first, second, and third outflow blocking plates 41b1, 41b2, and 41b3 also operate independently through their respective opening and closing actuators 43. That is, in the case of the embodiment shown in FIG. 4, the six outflow blocking plates provided in the multi-stage sterilization dryer 10 operate independently.

When the outflow-side blocking flap 41b rotates upward to block the outlet 31q, the exhaust passage 31c is opened. Further, when the outflow-side blocking flap 41b rotates downward, the outlet 31q is opened and the exhaust passage 31c is blocked.

In addition, a supply passage 31b is provided on one side of each cabinet 31 and an exhaust passage 31c is provided on the other side. The supply passage 31b and the exhaust passage 31c are located on opposite sides with the processing space 31a interposed therebetween and are partitioned by a vertical partition plate 38.

The supply passage 31b is a passage through which air rising from the bottom passes upward, and the exhaust passage 31c is a passage through which air coming down from the top passes downward. The supply passage 31b and the exhaust passage 31c are formed three by one by the vertical diaphragm 38 described above. The supply passage 31b corresponds to the inlet 31p and the exhaust passage 31c corresponds to the outlet 31q on a one-to-one basis.

On the other hand, the air induction means includes the above-described inlet-side blocking flap (41a) and outlet-side blocking flap (41b) and the opening and closing drive unit (43).

The inlet-side blocking flap 41a selectively blocks the inlet 31p and the supply passage 31b, allowing air to flow into the processing space 31a through the inlet 31p or upward through the supply passage 31b. make it fluid

In addition, the outflow-side blocking flap 41b opens the outlet 31q together when the inlet-side blocking flap 41a opens the inlet 31p, and simultaneously blocks the outlet 31p when blocking the inlet 31p. . The air introduced into the processing space 31a circulates through the processing space and then drains downward.

In the sterilization dryer 10 of this embodiment having the above configuration, each unit sterilization and drying box 30 can be independently operated as described above. For example, operating only one of the unit sterilization drying boxes 30 on the 1st, 2nd and 3rd floors, or unit sterilization and drying boxes 30 on the 1st and 2nd, 2nd and 3rd, and 1st and 3rd floors It is possible to select and operate, or operate all of the 1st, 2nd, and 3rd floors simultaneously.

This selective operation is implemented by air induction means under the control of the controller 37. For example, when the inlet 31p of the processing space 31a of the floor to be operated is opened, air is supplied to the processing space 31a of the corresponding floor to be operated. If the inlet 31p is blocked, air is not supplied, so naturally, the operation of the corresponding layer does not proceed.

The operation of the sterilization dryer 10 having the above configuration is performed as follows.

First, in order to use only the unit sterilization drying box 30 on the first floor, the first, second, and third inflow blocking plates 41a1, 41a2, and 41a3 on the first floor are rotated in the direction of the arrow b in FIG. The inlet 31p is opened. In this way, all the air supplied from the blowing module is supplied to the unit sterilization drying box on the first floor. The air introduced into the unit sterilization drying box on the first floor flows downward through the outlet 31q and then exits to the outside through the exhaust port 21f.

In order to use only the unit sterilization and drying box 30 on the second floor, the first, second, and third inlet blocking plates 41a1, 41a2, and 41a3 of the first floor unit sterilization and drying box 30 are rotated in the direction of the arrow a to enter the inlet ( 31p) is blocked and at the same time the supply passage 31b is opened. At the same time, all the inlets 31p of the unit sterilization drying box 30 on the second floor are opened, and the first, second, and third outflow blocking plates 41b1, 41b2, and 41b3 on the second floor are rotated downward to remove the outlet 31q. open the

Accordingly, the air supplied from the blower module 20 passes upward through the supply passage 31b of the unit sterilization and drying box on the first floor, passes through the inlet 31p of the unit sterilization and drying box on the second floor, and enters the processing space 31a on the second floor. fill in In addition, the air filling the processing space on the second floor flows downward through the exhaust passage 31c of the unit sterilization and drying box on the first floor through the open outlet 31q and then is exhausted through the exhaust port 21f.

In addition, when only the unit sterilization drying box 30 on the third floor is to be used, both the inlets 31p of the first and second floor unit sterilization drying boxes are blocked, and the outlet 31q of the third floor unit sterilization drying box is opened. . In this state, the air supplied from the blower module 20 passes through the first and second floor supply passages 31b in order, and then flows into the treatment space 31a through the inlet 31p of the unit sterilization and drying box on the third floor. Then, it is discharged to the lower part through the third floor outlet 31q. The air discharged through the outlet 31q is exhausted through the exhaust port 21f via the exhaust passage 31c on the second floor and the exhaust passage 31c on the first floor.

In order to selectively use only the first and second floor unit sterilization drying boxes 30, select any one or two inflow blocking plates among the first, second, and third inflow blocking plates 41a1, 41a2, and 41a3 on the first floor by arrow b. change direction Also, at this time, the second-layer inflow blocking plate lowers the inflow blocking plate located above the inflow blocking plate that does not rotate in the direction of arrow b among the first-layer blocking plates in the direction of arrow b. Going down in the direction of the arrow b means opening the inlet 31p.

For example, if the first and third inflow blocking plates 41a1 and 41a3 on the first floor are lowered in the direction of arrow b, the second inflow blocking plate on the second floor is lowered in the direction of arrow b. Similarly, if the first inflow blocking plate on the first floor is lowered in the direction of arrow b, the second and third inflow blocking plates on the second floor are lowered in the direction of arrow b.

As the inflow blocking plate is rotated in the direction of the arrow b, air flows into the processing space 31a. When the two inflow blocking plates are rotated in the direction of the arrow b, 2/3 of the air supplied from the blower module 20 flows in. When only one inlet blocking plate is rotated in the direction of arrow b, 1/3 of the air flows into the processing space.

In this way, a part of the air coming up from the blowing module 20 flows into the unit sterilization drying box 30 on the first floor, and the remaining air moves upward through the supply passage 31b. Air does not rise through the third-floor supply passage 31b.

The air supplied to the first and second floors moves downward through the outlet 31q and is discharged through the exhaust port 21f.

In addition, in order to select and use only the 2nd and 3rd floor unit sterilization and drying boxes 30, raise all the first, second and third inlet blocking plates 41a1, 41a2 and 41a3 on the first floor in the direction of the arrow a. In addition, any one or two inflow blocking plates of the first, second, and third inflow blocking plates of the second floor are lowered in the direction of the arrow b, and the first, second, and third outflow blocking plates of the second and third layers (41b1, 41b2 , 41b3) rotates downward to open the outlet 31q.

Part of the air supplied from the blower module 20 in the above state is supplied to the 2-story unit sterilization drying box and the rest to the 3-story unit sterilization drying box.

If you want to selectively use the unit sterilization and drying boxes 30 on the first and third floors, rotate the first, second, and third inlet blocking plates 41a1, 41a2, and 41a3 on the second floor in the direction of the arrow a to open the inlet port 31p. is blocked, and any one or two inflow blocking plates among the first, second, and third inflow blocking plates 41a1, 41a2, and 41a3 on the first floor are rotated in the direction of the arrow b. In addition, the first, second, and third outflow blocking plates 41b1, 41b2, and 41b3 of the third layer are rotated downward to open the outlet 31q.

Part of the air supplied from the blower module 20 enters the processing space 31a on the first floor, and the remaining air is supplied to the processing space 31a on the third floor through the open supply passage 31b.

Finally, in order to use all of the unit sterilization drying boxes 30 on the 1st, 2nd, and 3rd floors, any one of the first, second, and third inflow blocking plates 41a1, 41a2, and 41a3 on the first floor, the first, Rotate any one of the 2 and 3 inflow blocking plates 41a1, 41a2, and 41a3 in the direction of the arrow b. At this time, among the second-layer inflow blocking plates, only one of the inflow blocking plates located on the upper side of the inflow blocking plates that do not rotate in the direction of arrow b among the first-layer inflow blocking plates is lowered in the direction of arrow b. For example, if the second inflow blocking plate 41a2 of the first, second, and third inflow blocking plates on the first floor is lowered in the direction of arrow b, in the case of the second floor, the first inflow blocking plate 41a2 among the first, second, and third inflow blocking plates is lowered. Either the blocking plate 41a1 or the third inflow blocking plate 41a3 is lowered in the direction of the arrow b. At this time, the outlets 31q on the second and third floors must also be opened.

In this state, the air supplied from the blower module 20 is distributed to the processing spaces 31a on the first, second and third floors by 1/3.

The above operation example describes an operation example of a multi-stage sterilization dryer configured by stacking unit sterilization and drying boxes 30 in three layers. It can also be applied to stacked multi-stage sterilization dryers.

In addition, in the above operation example, the inflow blocking flap 41a is omitted in the unit sterilization and drying box (30, ie, 3rd floor) located on the top floor, and the outflow is omitted in the unit sterilization and drying box (30, ie, 1st floor) located on the lowest floor. Although the case where the side blocking flap 41b is omitted has been described, the inflow side blocking flap 41a is provided in the unit sterilization drying box 30 (ie, the third floor) located on the top floor, and the unit sterilization drying box located on the lowest floor Even when the outflow side blocking flap 41b is provided in (30, ie, the first floor), the method of opening and closing the inflow side blocking flap 41a and the outflow side blocking flap 41b can be applied in the same way.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention.
