Description

UV sterilizer {AN UV STERILZER}

The following example relates to a UV sterilizer for sterilizing various harmful bacteria by a UV sterilization lamp.

Generally, the human body is sweating during sleep in accordance with the constitutional differences of the autonomic nerves in order to control the body temperature in a special environment, a change of season and humidity or a special disease, and the skin as a protective film for protecting the skin and protecting the skin, When you do, you will fall off your body. Sweat and keratin from the human body are infiltrated into bed mattresses, bedding such as futons, pillows, and the like to adjust the environment where house dust mites and bacteria and / or fungi reproduce. Accordingly, skin diseases (typically atopic) or respiratory diseases (typically asthma) are likely to be induced or intensified.

Furthermore, in the case of a home where pets such as dogs or cats are housed indoors, dirt such as hair and dandruff falling on the pet is likely to penetrate into the tissues of the bedding or carpet or clothing, The use of bedding, carpets or garments for which the same dirt has not been properly removed may also cause or intensify respiratory diseases such as skin diseases such as atopic dermatitis or rhinitis.

1 is a perspective view showing an ultraviolet sterilizer 1 according to an embodiment.

The ultraviolet sterilizer 1 includes a central housing 20 for accommodating a controller, a controller including a display and a control circuit, a side housing 10 rotatably connected to one side of the central housing 20, .

The side housing 10 can accommodate a UV germicidal lamp and emits ultraviolet light when powered by a UV germicidal lamp. The arrangement of the UV sterilizing lamp will be described later in detail in FIGS.

The central housing 20 may be configured, for example, in the form of a rectangular frame, and the display may be disposed on the top surface. The display may be configured in the form of a touch screen, and the ultraviolet sterilizer 1 may be operated by a user's hand touch. In addition, the shape of the central housing 20 is not limited, and may have a circular, triangular, or polygonal shape larger than a square.

The two side housings 10 may be provided symmetrically on both sides of the central housing 20. The two side housings 10 may be provided as two side housings 10, The side housings 10 may be provided in more than one manner, which may be arranged radially along the circumference of the central housing 20.

Fig. 2 shows a process in which the side housing 10 of the ultraviolet sterilizer 1 according to the embodiment is folded. Fig. 3 shows a fully folded side housing of the ultraviolet sterilizer according to the embodiment.

The side housing 10 can be folded with respect to the center housing 20 by a hinge 30. The side housing 10 can be folded up to 90 degrees at 180 degrees with respect to the center housing 20 and can be fixed at a midpoint between them.

As shown in FIG. 2, when the side housing 10 is rotated at a certain angle with respect to the center housing 20 and then fixed at an angle, for example, the sterilization operation is performed on the bedding that is hooked in the same shape as the tent .

The side housing 10 is completely folded at 90 degrees with respect to the center housing 20 as shown in Fig. In this case, since the entire length is reduced to about half of the state in which the side housing 10 of the ultraviolet sterilizer 1 is completely opened, it is easy for the user to carry the ultraviolet sterilizer 1 and takes up a small volume, It can be stored in space.

4 is a perspective view showing a state in which the length of the side housing 10 of the ultraviolet sterilizer 1 according to the embodiment is adjusted.

The side housing 10 includes a first side housing 110 rotatably connected to one side of the center housing 20 and a second side housing 110 housed in the first side housing 110 and protruding from the first side housing 110 Two side housings 120 may be included.

The second side housing 120 may have a length that is substantially the same as, or somewhat shorter than, the first side housing 110, for example, when the side housing 10 is fully protruded from the first side housing 110, The entire length can be extended up to twice the length before being projected.

The second side housing 120 can be fixed in a state of being completely received in the first side housing 110 and in an intermediate state of fully protruding from the first side housing 110. [ Thus, the side housing 10 can correspondingly adjust its length depending on the size of the various mattresses present in the market.

Fig. 5 shows a state in which the ultraviolet sterilizer 1 according to the embodiment is actually moving on the mattress.

5 (a) shows a state in which the mattress in the longitudinal direction is moved upwards in a state in which the length of the side housing 110 of the ultraviolet sterilizer 1 is set short. The side housing 110 shown in FIG. 5 (a) is in a state in which the second side housing 120 is completely housed in the first side housing 110.

5 (b) shows a state in which the mattress is moved vertically in the longitudinal direction with the length of the side housing 110 of the ultraviolet sterilizer 1 set long. The side housing 110 shown in FIG. 5 (b) is in a state in which the second side housing 120 protrudes from the first side housing 110.

When the sterilizing time is desired to be longer on the mattress or when thorough sterilization is required, the ultraviolet sterilizer 1 can be used in a state as shown in Fig. 5 (a). If quick sterilization is required, the ultraviolet sterilizer 1 can be used in the same state as in (b).

In addition, since the ultraviolet ray lamp using a relatively weak ultraviolet ray can be used in the case of the central housing portion, the ultraviolet ray sterilizer 1 is moved in a state as shown in Fig. 5 (a) When the sterilizer 1 is moved, a thorough sterilization operation for the entire mattress can be performed so that there is no insufficient sterilizing portion.

6 is a perspective view showing the arrangement structure of the UV sterilization lamp 40 and the separation wall 130 of the side housing 10 of the ultraviolet sterilizer 1 according to the embodiment. 6 (a) shows a state in which the second side housing 120 does not protrude from the first housing 110, and FIG. 6 (c) shows a state in which the second side housing 120 protrudes from the first housing 110 And FIG. 6 (b) shows the separating wall 130. FIG.

The UV sterilizing lamp 40 installed in the side housing 10 includes a first UV sterilizing lamp 41 fixed to the first side housing 110 and a second sterilizing lamp 41 fixed to the second side housing 120. [ (42). Accordingly, the second sterilizing lamp 42 can move together when the second housing 120 moves. For example, each of the first UV sterilization lamp 41 and the second sterilization lamp 42 may be composed of a single long lamp, and may be composed of a plurality of divided lamps.

Therefore, when the length of the side housing 10 is increased by protruding the second housing 120 from the first side housing 110, the range for irradiating ultraviolet light can be substantially doubled.

The first UV sterilization lamp 41 and the second sterilization lamp 42 may be arranged in a direction parallel to the longitudinal direction of the side housing 10, respectively. Accordingly, the first UV sterilizing lamp 41 and the second sterilizing lamp 42 are arranged in parallel with each other.

At the end of the first housing 110, side wheels 115 and 125, which are arranged in a direction perpendicular to the longitudinal direction of the first housing 110, may be provided. The side wheels 115, 125 can assist in facilitating movement of the ultraviolet sterilizer 1 in the vertical direction in the longitudinal direction.

The side wheels 115 and 125 include a first side wheel 115 provided at the distal end of the first housing 110 and a second side wheel 125 provided at the distal end of the second housing 120, . ≪ / RTI >

Two first side wheels 115 may be spaced apart from each other on a thin plate covering the first housing and a second side wheel 125 may be disposed adjacent to the spaced- .

Since the side housing 10 is supported by a total of three wheels, the ultraviolet sterilizer 1 can be supported by three points on the move. The side housings 10 may be supported by six wheels arranged on the two side housings 10 when provided on both sides of the central housing 20. [ Therefore, even when the ultraviolet sterilizer 1 passes the curved mattress, the ultraviolet sterilizer 1 can stably move without overturning or tipping over.

The side housing 10 may include a separation wall 130 disposed between the first UV germicidal lamp 41 and the second germicidal lamp 42. The separating wall 130 is fixed within the first side housing 110 and does not interfere with or affect the movement of the second side housing 120.

For example, the separating wall 130 is formed of a "C" shaped frame, and has an upper end and an open end, and may have an internal space 131. The separation wall 130 may be secured to the first side housing 110 such that the open top faces downward.

The first UV germicidal lamp 41 and the second germicidal lamp 42 are disposed between the first UV germicidal lamp 41 and the second germicidal lamp 42, And may be spaced from each other in a direction parallel to the longitudinal direction.

7 schematically shows a state in which the separating wall 130 provided in the side housing 10 and the UV sterilizing lamp 40 are connected by the wire 140. Fig. 7 (a) shows a state in which the second side housing 120 is inserted into the first side housing 110 as shown in FIG. 6 (a), and FIG. 7 (b) 2 shows a state in which the side housing 120 protrudes from the first side housing 110.

One end of the wire 140 may be fixed to the lower end of the point where the first side housing 110 and the center housing 20 contact with each other and the other end of the wire 140 may be fixed to the rear end of the second sterilizing lamp 42 Can be connected. The middle portion of the wire 140 may be inserted into the inner space 131 of the separating wall 130. [

The bent portion of the wire 140 inserted in the inner space 131 of the separation wall 130 and the separation wall 130 may be connected by the elastic body 150. As the elastic body 150, for example, a spring, a rubber band, or the like may be used.

The elastic body 150 may include a ring at both ends and the ring disposed at one end is caught by the bent portion of the wire 140 and the ring disposed at the other end is disposed at the distal end of the separation wall 130 It can be caught in a groove or a hole.

The other end of the elastic body 150 is fixed to the separating wall 130 away from the central housing 20 so that substantially the majority of the wire 140 is placed in the inner space 131 of the separating wall 130 .

7 (b), when the second sterilizing lamp 42 moves together with the second side housing 120, a middle portion of the wire 140 may be exposed to the outside of the inner space 131. In this case, as the elastic body 150 is deformed, the elastic body 150 can be pulled tight so that the wire 140 is not twisted or interrupted, and the second side housing 120 is again inserted into the first side housing 110 So that the restoring force can be provided.

At this time, the ultraviolet light emitted from the first UV germicidal lamp 41 existing at the opposite side of the separation wall 130 may not be directly irradiated to the wire 140 by the separation wall 130.

The temperature of the wire 140 may be excessively increased by ultraviolet rays when the ultraviolet rays are radiated to the wire 140. However, It is possible to prevent the temperature of the wire 140 from excessively increasing.

FIG. 8 is a perspective view showing the rear surface of the ultraviolet sterilizer 1 according to the embodiment, and FIG. 9 is a perspective view showing a UV sterilizing lamp around the central housing 20 of the ultraviolet sterilizer 1 according to the embodiment.

Since the side housing 10 has been described in detail with reference to FIGS. 1 to 7, the description of the overlapping portions will be omitted.

When a UV sterilizing lamp is disposed only in the side housing 10, a sufficient amount of ultraviolet rays may not be irradiated to the central portion of the mattress. Thus, a central UV lamp 210 may be provided on the lower surface of the central housing 20 to match the size of the central housing 20.

When the central housing 20 is configured as a rectangular frame, the central UV lamp 210 may be arranged in a diagonal direction of the rectangle. In this case, since the length of the central UV lamp 210 can be longer than the length corresponding to the height or width of the quadrangle, a UV lamp having a relatively large amount of ultraviolet irradiation among the central UV lamp 210 can be selected and used .

The side housing 10 needs to be folded to 90 degrees with respect to the center housing 20 so that the UV sterilizing lamp can not be disposed on the side where the side housing 10 and the central housing 20 are rotated.

Accordingly, the auxiliary housing 160, which is rotatably fixed to the side housing 10, may be disposed to enable irradiation of ultraviolet light to such a portion. The auxiliary housing 160 may receive a relatively small auxiliary UV lamp 170.

The UV sterilizing lamps 41 and 42 disposed in the side housing 10 and the auxiliary UV lamp 170 are arranged to extend from each other around the portion where the auxiliary housing 160 and the first side housing 110 are connected The direction may be the opposite direction.

Two drive wheels 220 may be provided on both sides of the central housing 20, and the drive wheels 220 may be driven by a drive source. Removal of the lower end cover 250 of the central housing 20 can confirm the arrangement of the drive sources, as shown in FIG.

In the central portion of the central housing 20, two center wheels 230 may be provided to assist in driving the drive wheels 220. [ The center wheel 230 is disposed on the upper and lower sides of the lower end of the central housing 20 and the driving wheel 220 is disposed on the left and right sides of the lower end of the center housing 20, , It can move upright without overturning or falling over.

A plug 240 for external power supply may be provided at the rear end of the central housing 20 so that external power may be supplied thereto and a battery disposed inside the central housing 20 may be charged .

Referring to FIG. 9, it can be seen that the auxiliary housing 160 is fixed to the first side housing 110.

The auxiliary housing 160 includes an auxiliary frame 162 arranged centrally from the edge of the first side housing 110, a wing 163 rotatably connected to the auxiliary frame 162 and receiving the auxiliary UV lamp 170 And an auxiliary hinge 161 for rotating the wing 163 from the auxiliary frame 162. [

The wings 163 can pivot from the first side housing 110 toward the center housing 20 about the hinge 162.

10 shows a state in which the auxiliary housing 160 is folded to the side housing 10 of the (1) ultraviolet sterilizer according to the embodiment.

When the auxiliary housing 160 is in the unfolded state when the side housing 10 is folded with respect to the central housing 20, it may interfere with the movement of the side housing 10, There is a need.

The side housing 10 can be folded while rotating inward in the A direction about the center housing 20, as shown in Fig. At the same time, the auxiliary housing 160 can be folded while rotating in the direction B about the auxiliary hinge 161.

Therefore, when the side housing 10 rotates, the direction A in which the side housing 10 rotates and the direction B in which the auxiliary housing 160 rotates may be opposite. In this state, the auxiliary UV lamp 170 can be covered by a blade 163 that rotates about the auxiliary hinge 161, and a part of the auxiliary UV lamp 170 can overlap with the UV sterilizing lamp accommodated in the side housing 10 have.

The side housing 10 and the auxiliary housing 160 are rotated in opposite directions so that the side housing 10 can be completely folded at 90 degrees with respect to the center housing 20 without interference from the rotation of the auxiliary housing 160.

 11 shows the inside of the central housing 20 of the ultraviolet sterilizer 1 according to the embodiment and shows the inside of the central housing 20 with the cover 250 shown in Fig. 8 removed.

The drive wheel 220 may be driven by an electric motor-type drive source 60. The two driving wheels 220 are not driven by one driving source but are driven by the respective driving sources 60 and each driving source 60 is connected to the control circuit Can be controlled separately.

The central housing 20 can be connected to the side housing 10 by hinges 30 provided on both sides. The side housing 10 can accommodate the UV germicidal lamps at regularly spaced locations to accommodate the drive wheels 220.

On one side of the central housing 20, an ion cluster module 50 may be installed. The ion cluster module 50 can generate ions to achieve additional germicidal effects.

On the center side of the ion cluster module 50, a fan 80 is provided so that wind containing ions can be emitted toward the side housing 10.

At the lower end of the ion cluster module 50, a smell diffusion module that emits a flavor may be installed. The smell diffusion module may be, for example, in the form of a solid gel type cartridge, and may be replaceable when the cartridge is exhausted.

The smell diffusion module may be disposed between the fan (80) and the ion cluster module (50). Further, the smell diffusion module can be replaced by opening the incompatible cartridge exchange cover provided on one side of the cover 250.

The sterilizing ions generated in the ion cluster module 50 and the fragrance generated in the smell module can be mixed with air and mixed with each other and the mixed air can be diverted toward the side housing 10 by the fan 80 .
