The toilet sterilizer 10 according to the present invention is installed on the inner wall of the toilet cover 4 . The toilet sterilizer 10 installed on the toilet cover 4 is not fixed as in the prior art, but moves according to the opening and closing of the toilet cover 4 .

The toilet sterilizer 10 includes a case 101 , a hinge portion 104 hingedly coupled to the case 101 , and a support 105 that is fastened or attached to the toilet cover 4 .

The case 101 is composed of an upper case 101a and a lower case 101b. The upper case 101a and the lower case 101b are coupled to each other to constitute the body of the toilet sterilizer 10 . A recess 101-1 for accommodating the hinge part 104 and hinge-joining the hinge part 104 is formed in the upper center of the case 101 .

The inside of the case 101 constituting the body includes an ultraviolet LED 102, a battery, a circuit board, and the like. In addition, a motion detection sensor capable of detecting a positional movement of the case 101 may be provided inside the case 101 . A Hall sensor may be used as the motion sensor.

The ultraviolet LED 102 constitutes the ultraviolet sterilization unit, and irradiates ultraviolet rays (UV-A or UV-C) for sterilization of the toilet. The battery is composed of a dry battery, a secondary battery, and the like, and supplies power to the toilet sterilizer 10 . In addition, the toilet sterilizer 10 may receive power through an adapter in addition to the battery.

A control chip (MCU) for controlling the sterilization operation of the toilet sterilizer 10 is mounted on the circuit board. The control chip (MCU) constitutes the control unit, which will be described later with reference to FIG. 4 .

* UV LEDs 102 are disposed on both ends of the upper case, both ends of the lower case, and on the bottom of the case so that ultraviolet rays are irradiated from the front, rear, and bottom surfaces of the case 101 . In the embodiment of the present invention, eight UV LEDs 102a are disposed on the four corners of the upper case of the square shape that is the front side of the case 101 and the four corners of the lower case of the square shape that is the rear side of the case 101 , One ultraviolet LED 102b is arranged on the bottom surface.

An insertion hole 103 into which the rotary shaft bar 20 is inserted is formed on the side surface of the case 101 . One side of the rotary shaft bar 20 is installed in the toilet cover 4, and the other side is inserted into the insertion hole 103 of the case 101 to support the case 101 and the hinge rotation of the case 101 is made stably. let it go

* One side of the hinge part 104 is attached to the support 105 and the other side is hinged to the case 101 so that the case 101 is hinged. The hinge part 104 has a configuration in which an upper hinge plate and a lower hinge plate are fastened, and a tilt sensor 106 (see FIG. 4 ) is built in a space provided by fastening the two hinge plates. That is, the hinge part 104 is inserted into the hinge ball 101-2 formed in the recess 101-1 of the case 101 and the hinge shaft part 104-1 and the hinge shaft part 104-1 are hinge-coupled.

When the toilet cover 4 is opened, the case 101 constituting the body of the toilet sterilizer 10 is placed in contact with the inner wall of the toilet cover 4 . Since the thickness of the case 101 according to the present invention is substantially the same as or smaller than the inner thickness of the toilet cover 4, the protrusion is not great, and when the user sits on the toilet seat 3 and uses the toilet, the user's back is placed on the toilet seat sterilizer. (10) The problem of touching and causing inconvenience rarely occurs.

When the toilet cover 4 is open, the UV LED 102 of the toilet sterilizer 10 does not emit light.

When the toilet cover 4 is closed, the case 101 rotates along the axis of rotation of the hinge shaft portion 104-1 of the hinge portion 104 as much as the angle at which the toilet cover 4 is closed to be spaced apart from the inner wall of the toilet cover 4 You will enter the toilet room (2) of That is, when the user closes the toilet cover 4 after going to the toilet, the toilet cover 4 goes down and the case 101 rotates along the axis of rotation of the hinge part 104 by the internal load.

Referring to FIG. 3A , when the toilet cover 4 is half-closed, the case 101 rotates by that angle, and the toilet cover 4 is in contact with the inner wall of the toilet cover 4 when it is open. It can be seen that it is located while maintaining the same direction of gravity as .

Then, as shown in FIG. 3 (b), when the toilet cover 4 is completely closed, the case 101 rotates further by the remaining angle while maintaining the direction of gravity while maintaining the direction of gravity and positioned perpendicular to the inner wall of the toilet cover 4 do. As described above, the toilet sterilizer 10 rotates approximately 90 degrees from its initial position to become vertical with respect to the inner wall of the toilet cover 4 and is horizontally hung in the toilet room 2 .

If the sterilizer sterilizer 10 is hung in the longitudinal direction in the toilet room 2, the UV irradiation range is expanded up and down to increase the sterilization effect.

The irradiation range of ultraviolet (UV) LEDs generally ranges from 120° to 160° vertically and horizontally. In particular, according to the present invention, four UV LEDs 102a located on the front and rear surfaces of the case 101 are positioned between the toilet cover and the toilet seat, thereby sterilizing the toilet cover and the toilet seat without omission.

Referring to FIG. 5 , as shown in (a), the conventional product has a limited ultraviolet irradiation range, but as shown in (b), the toilet sterilizer 10 according to the present invention is the case 101. Four UV LEDs 102a disposed on the front and back sides, respectively, sterilize the upper and lower portions of the toilet seat (toilet seat) and the rim (RIM) 5 (the portion where water from the toilet tank descends into the toilet). The UV LED 102b disposed on the bottom of the case 101 sterilizes even the water inside the toilet room 2 .

4 is a view showing the internal configuration of a toilet sterilizer according to an embodiment of the present invention.

Referring to FIG. 4 , the toilet sterilizer 10 is mechanically composed of a case 101 and a hinge unit 104 , and the case 101 includes a battery, an ultraviolet LED 102 , a control unit 107 , and the like. and a tilt sensor 106 is built in the hinge portion 104 .

In addition, as another embodiment, when a motion detection sensor is built in the case 101 in addition to the battery, the UV LED 102 , and the control unit 107 , the hinge unit 104 does not need a separate inclination sensor 106 .

When the toilet cover 4 is opened or closed, there is little change in inclination because the case 101 always maintains the position in the direction of gravity through the hinge rotation, whereas the hinge 104 actually rotates so that the inclination is reduced. will change Accordingly, a tilt sensor 106 for detecting a change in inclination of the hinge part 104 is built in the hinge part 104 . In the embodiment of the present invention, the inclination sensor 106 may be built in the support connection part 104-2 of the hinge part 104.

The control unit 107 periodically receives a detection signal from the inclination sensor 106 and senses the rotation of the hinge unit 104 . The control unit 107 processes the detection signal to recognize that the toilet cover 4 is closed when the rotation amount of the hinge unit 104 exceeds a threshold (eg, 80 to 90 degrees) and operates the UV LED 102 . .

When it is determined that the toilet cover 4 is closed, the control unit 107 operates the UV LED 102 after a predetermined time to perform a sterilization operation. UV irradiation may be performed for a preset time or may be continuously or periodically performed. The UV LED 102 emits UV light to sterilize harmful bacteria present in the toilet.

When the user opens the toilet cover 4 while the toilet cover 4 is closed and the UV light is being irradiated, the control unit 107 controls the hinge portion 104 based on the detection signal of the inclination sensor 106 . By detecting the decrease in the amount of rotation, the irradiation of the ultraviolet LED 102 can be stopped.

* In Figure 4, although the hinge part 104 shows a configuration in which the inclination sensor 106 is built-in, the tilt sensor 106 is not built in the hinge part 104. Instead, the motion detection sensor is located in the case 101. can be built-in.

In this case, the control unit 107 periodically receives a detection signal from the motion detection sensor to detect the movement of the position of the case 101 . The control unit 107 processes the detection signal to detect that the position of the case 101 is moved, recognizes that the toilet cover 4 is closed, and operates the UV LED 102 . A Hall sensor may be used as the motion sensor, and a magnet is attached to a portion in contact with the case 101 of the seat cover 4 in order for the Hall sensor to detect a magnetic force.

Also, the magnet may be embedded in the hinge part 104 , in which case the magnet may be installed at the upper end of the hinge part 104 , that is, a portion attached to the support 105 . This is because, when the case 101 rotates along the axis of rotation of the hinge part 104 , the upper end of the case 101 and the hinge part 104 approaches or moves away from each other. In this case, the motion detection sensor (Hall sensor) built into the case 101 may be installed at a portion that is farther away from or closer to the upper end of the hinge unit 104 .

The above detailed description should not be construed as restrictive in all respects and should be considered as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.

The sterilizer according to the present invention can be widely used to sterilize the inside of various products with lids, including toilets.
