However, when the user sits on the seat of a Western-style toilet, the sterilizing device installed on the lid protrudes, causing discomfort when the sterilizing device touches the user's back. Therefore, the sterilizer is installed at a low position on the lid, and as a result, when the lid is closed, it does not penetrate deep into the toilet body, making it impossible to effectively sterilize the inside of the toilet body. There is a problem.

Further, the sterilizer was attached to the toilet lid and was configured to irradiate UV LED light only downward. Therefore, it is not possible to directly irradiate the toilet seat, which comes into direct contact with human skin, and the lower part of the toilet seat, where filth is thrown up and bacteria tend to breed, and there is a problem in that there is a limit to sterilization.

The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to provide a Western-style toilet sterilizer that can effectively sterilize the inside of the toilet body. be.

Further, the Western-style toilet sterilizing device according to the present invention is a Western-style toilet sterilizing device installed on the toilet lid, and includes a housing having a built-in ultraviolet sterilizing section, and a hinge connected to the housing and having a built-in tilt sensor. and a support member fastened to the toilet lid to which the hinge portion is attached, and when the toilet lid is open, the casing is positioned in contact with the inner wall of the toilet lid, and the ultraviolet rays are When the toilet lid is closed without the sterilization section operating, the casing rotates along the rotation axis of the hinge section, and the casing maintains its inclination while gradually separating from the inner wall of the toilet lid. Meanwhile, the ultraviolet sterilization unit operates when the tilt sensor detects the tilt of the hinge part.

Furthermore, the Western-style toilet sterilizer according to the present invention is a Western-style toilet sterilizer that is installed on a toilet lid, and includes a casing in which an ultraviolet sterilizer and a motion detection sensor are built in, and a hinge part that is hinged to the casing. and a support member fastened to the toilet lid to which the hinge portion is attached, and when the toilet lid is open, the casing is positioned in contact with the inner wall of the toilet lid, and the ultraviolet sterilization is performed. When the toilet lid closes without moving the toilet lid, the casing rotates along the rotation axis of the hinge part and separates from the inner wall of the toilet lid, and the movement detection sensor detects the positional movement of the casing. It is characterized in that the ultraviolet sterilization unit operates upon detection.

As mentioned above, in the present invention, when the toilet lid is closed, the Western-style toilet sterilizer is not fixed and rotates along the rotation axis while maintaining the direction of gravity, so that the Western-style toilet sterilizer can be erected in the longitudinal direction. Since the ultraviolet rays penetrate deep into the toilet compartment of a Western-style toilet, the irradiation area of the ultraviolet rays is widened and the interior of the toilet can be more effectively sterilized, which is an outstanding effect.

Referring to FIGS. 1 to 3, a Western-style toilet sterilizer 10 according to the present invention is installed in a typical Western-style toilet.

Usually, a Western-style toilet consists of a toilet body 1, a water tank (not shown) that stores water for discharging water for removing feces into the toilet chamber 2 of the toilet body 1, and a tank installed on the top of the toilet body 1. It includes a toilet seat 3, a toilet lid 4 installed on the toilet seat 3, and the like.

Here, the toilet main body 1 includes a toilet chamber 2 where you relieve yourself, a toilet drainage channel (not shown) that prevents odor by storing water at a certain level, and a toilet drainage path (not shown) through which the toilet water is discharged by the water in the aquarium. It includes a toilet bowl rim that allows water from the aquarium to enter and drain into the toilet compartment 2 via an internal water channel.

The Western-style toilet sterilizer 10 according to the present invention is installed on the inner wall of the toilet lid 4. The Western-style toilet sterilizer 10 installed on the toilet lid 4 is not fixed as in conventional toilets, but moves when the toilet lid 4 is opened and closed.

The Western-style toilet sterilizer 10 includes a casing 101, a hinge part 104 hinged to the casing 101, a support 105 fastened to or attached to the toilet lid 4, and the like.

The housing 101 includes an upper housing 101a and a lower housing 101b. The upper casing 101a and the lower casing 101b are fastened together to constitute the body of the Western-style toilet sterilizer 10. A recess 101-1 is formed at the center of the upper end of the housing 101 to house the hinge part 104 and to be hingedly connected to the hinge part 104.

The interior of the casing 101 that constitutes the body contains an ultraviolet LED 102, a battery, a circuit board, and the like. Furthermore, a motion detection sensor that can detect the positional movement of the housing 101 may be provided inside the housing 101. A Hall sensor can be used as the motion detection sensor.

The ultraviolet LED 102 constitutes an ultraviolet sterilization section and irradiates ultraviolet light (UV-A or UV-C) for sterilizing a Western-style toilet. The battery is composed of a dry battery, a secondary battery, etc., and supplies power to the Western-style toilet sterilizer 10. Furthermore, power can be supplied to the Western-style toilet sterilizer 10 via an adapter in addition to the battery.

A control chip MCU for controlling the sterilization operation of the Western-style toilet sterilizer 10 is mounted on the circuit board. The control chip MCU constitutes a control section, which will be described later with reference to FIG.

The ultraviolet LEDs 102 are arranged at both end corners of the upper and lower casings and on the bottom surface of the casing so that ultraviolet rays are irradiated from the front, rear, and bottom surfaces of the casing 101. In the embodiment of the present invention, a total of eight ultraviolet LEDs 102a are arranged at four corners of a rectangular upper housing that is the front surface of the housing 101 and four corners of a rectangular lower housing that is the rear surface. One ultraviolet LED 102b is arranged on the bottom surface of the housing 101.

An insertion groove 103 into which the rotating shaft rod 20 is inserted is formed on the side surface of the housing 101. One end of the rotating shaft rod 20 is installed in the toilet lid 4, and the other end is inserted into the insertion groove 103 of the housing 101, so that the hinge rotation of the housing 101 can be performed stably while supporting the housing 101. do.

One end of the hinge part 104 is attached to the support body 105, and the other end is hingedly connected to the housing 101 to rotate the housing 101 through the hinge. The hinge portion 104 has a structure in which an upper hinge plate and a lower hinge plate are fastened together, and a tilt sensor 106 (see FIG. 4) is built in the space created by the fastening of both hinge plates. That is, the hinge portion 104 includes a hinge shaft portion 104-1 that is inserted into a hinge hole 101-2 formed in a recess 101-1 of the housing 101 and is hinge-coupled, and a hinge shaft portion 104-1 that extends into the hinge shaft portion 104-1. A support connecting portion 104-2 is attached to the support 105.

The support 105 to which the support connection part 104-2 of the hinge part 104 is attached is attached to the toilet lid 4 with adhesive or fastened to the toilet lid 4 by screwing bolts and nuts, and is removable during cleaning. It is.

When the toilet lid 4 is open, the casing 101 forming the body of the Western-style toilet sterilizer 10 is positioned in contact with the inner wall of the toilet lid 4. Since the thickness of the casing 101 according to the present invention is approximately the same as or smaller than the inner thickness of the toilet lid 4, the protrusion does not feel large, and when the user sits on the toilet seat 3 and relieves himself, the user's back will be exposed to a Western-style toilet. The problem of discomfort caused by touching the sterilizer 10 rarely occurs.

When the toilet lid 4 is open, the ultraviolet LED 102 of the Western-style toilet sterilizer 10 does not emit light.

When the toilet lid 4 is closed, the casing 101 rotates along the axis of rotation of the hinge shaft portion 104-1 of the hinge portion 104 by the angle at which the toilet lid 4 is closed, and moves away from the inner wall of the toilet lid 4 while closing the toilet lid 4. You will now be able to enter toilet room 2. That is, when the user closes the toilet lid 4 after relieving himself, the toilet lid 4 moves downward and the housing 101 rotates along the axis of rotation of the hinge portion 104 due to the internal load.

As shown in FIG. 3(a), when the toilet lid 4 is about half closed, the casing 101 is rotated by that angle, so that when the toilet lid 4 is open, it comes into contact with the inner wall of the toilet lid 4. It can be seen that the object is positioned while maintaining the same direction of gravity as before.

Next, as shown in FIG. 3(b), when the toilet lid 4 is fully closed, the casing 101 further rotates by the remaining angle and continues to maintain the gravity direction against the inner wall of the toilet lid 4. vertical position. In this way, the Western-style toilet sterilizer 10 rotates approximately 90 degrees from its initial position, becomes perpendicular to the inner wall of the toilet lid 4, and is installed laterally within the toilet compartment 2.

When the Western-style toilet sterilizer 10 is installed in the toilet compartment 2 in the longitudinal direction, the irradiation range of ultraviolet rays is expanded vertically, and the sterilization effect can be increased.

The irradiation range of UV LED typically extends from 120° to 160° vertically and horizontally. In particular, in the present invention, the four UV LEDs 102a located on the front and rear surfaces of the housing 101 are positioned between the toilet lid and the toilet seat to evenly sterilize the toilet lid and the toilet seat.

Referring to FIG. 5, as shown in FIG. 5(a), the conventional product has a limited ultraviolet irradiation range, but as shown in FIG. 5(b), the Western-style product according to the present invention The toilet sterilizer 10 has four UV LEDs 102a arranged on the front and rear surfaces of a casing 101, respectively. Sterilize up to (part). The UV LED 102b placed on the bottom of the housing 101 sterilizes even the water inside the toilet compartment 2.

FIG. 4 is a diagram showing the internal configuration of a Western-style toilet sterilizer according to an embodiment of the present invention.

Referring to FIG. 4, the Western-style toilet sterilizer 10 is mechanically composed of a casing 101 and a hinge part 104, and the casing 101 has a built-in battery, an ultraviolet LED 102, a control part 107, etc. A tilt sensor 106 is built into the hinge portion 104.

In another embodiment, if the housing 101 includes a motion detection sensor in addition to the battery, the ultraviolet LED 102, and the control unit 107, the hinge unit 104 does not require a separate tilt sensor 106.

When the toilet lid 4 is opened and closed, the casing 101 always maintains its position in the direction of gravity due to hinge rotation, so there is almost no change in tilt, whereas the hinge portion 104 actually rotates. The slope will change. As a result, a tilt sensor 106 for detecting changes in the tilt of the hinge section 104 is built into the hinge section 104. In an embodiment of the present invention, the tilt sensor 106 may be built into the support connecting portion 104-2 of the hinge portion 104.

The control unit 107 receives a detection signal periodically from the tilt sensor 106 and detects the rotation of the hinge unit 104 . When the control unit 107 processes the detection signal and the amount of rotation of the hinge unit 104 exceeds a threshold value (for example, 80 to 90 degrees), the control unit 107 determines that the toilet lid 4 is closed and operates the ultraviolet LED 102.

If it is determined that the toilet lid 4 is closed, the control unit 107 operates the ultraviolet LED 102 after a predetermined time to perform a sterilization operation. The ultraviolet irradiation may be performed for a predetermined period of time, or may be performed continuously or periodically. The ultraviolet LED 102 emits ultraviolet light to sterilize harmful bacteria present in a Western-style toilet.

If the user opens the toilet lid 4 while the toilet lid 4 is closed and irradiated with ultraviolet rays, the control unit 107 controls the amount of rotation of the hinge unit 104 to decrease based on the detection signal of the tilt sensor 106. By detecting this, the irradiation of the ultraviolet LED 102 can be interrupted.

Although FIG. 4 shows a configuration in which the tilt sensor 106 is built in the hinge part 104, a motion detection sensor may be built in the housing 101 instead of the tilt sensor 106 built in the hinge part 104. .

In such a case, the control unit 107 periodically receives a detection signal from the motion detection sensor and detects the positional movement of the housing 101. The control unit 107 processes the detection signal, determines that the toilet lid 4 is closed when the positional movement of the housing 101 is detected, and operates the ultraviolet LED 102. A Hall sensor can be used as the motion detection sensor, and a magnet is attached to the Hall sensor at a portion of the toilet lid 4 that is in contact with the casing 101 in order to detect magnetic force.

Further, the magnet may be built into the hinge section 104, but in this case, the magnet can be installed at the upper end of the hinge section 104, that is, at a location where it is attached to the support body 105. This is because when the housing 101 rotates along the rotation axis of the hinge part 104, the housing 101 and the upper end of the hinge part 104 move toward or away from each other. In this case, the motion detection sensor (Hall sensor) built into the casing 101 can be installed at a location away from or close to the upper end of the hinge section 104.

The above detailed description is not to be construed as restrictive in all respects, but is to be considered illustrative. The scope of the present invention must be determined by reasonable interpretation of the claims, and all changes within the equivalent range of the present invention belong to the scope of the present invention.

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