Referring to fig. 1 to 3, the toilet sterilization apparatus 10 according to the present invention is provided to a general toilet.
Generally, a toilet bowl includes: a toilet main body 1; a water tank (not shown) containing water to discharge water for removing feces into the toilet bowl 2 of the toilet main body 1; a toilet seat 3 provided at an upper portion of the toilet body 1; a toilet cover 4 disposed above the toilet seat 3; etc.
Here, the toilet body 1 includes: a defecation chamber 2 for defecation; a sewage drain (not shown) filled with water of a predetermined level to prevent bad smell and discharging feces by means of water of a water tank; and a toilet RIM (RIM) for allowing water to flow into the water tank through the internal waterway and to be discharged to the toilet bowl 2.
The toilet sterilization device 10 according to the present invention is provided to the inner wall of the toilet cover 4. The toilet sterilization device 10 provided in the toilet cover 4 is not fixed as in the prior art, but moves with the opening and closing of the toilet cover 4.
The toilet sterilization device 10 includes a housing 101, a hinge portion 104 hinge-coupled to the housing 101, a support 105 fastened or attached to the toilet cover 4, and the like.
The housing 101 includes an upper housing 101a and a lower housing 101b. The upper case 101a and the lower case 101b are fastened to each other to constitute the main body of the toilet sterilization apparatus 10. A groove 101-1 for receiving the hinge portion 104 and hinge-coupling with the hinge portion 104 is formed at the upper end center of the housing 101.
An ultraviolet LED 102, a battery, a circuit board, and the like are included in the inside of the housing 101 constituting the main body. Further, an action sensor capable of sensing the positional movement of the housing 101 may be provided inside the housing 101. As the motion sensing sensor, a hall sensor may be used.
The ultraviolet LED 102 constitutes an ultraviolet sterilization unit, and irradiates ultraviolet rays (UV-Sup>A or UV-C) for sterilizing the toilet bowl. The battery includes a dry battery, a secondary battery, and the like, and supplies power to the toilet sterilization device 10. Also, the toilet sterilization device 10 may receive power through an adapter in addition to a battery.
A control chip (MCU) for controlling the sterilizing operation of the toilet sterilizing device 10 is mounted on the circuit board. The control chip (MCU) constitutes a control section, which will be described later with reference to fig. 4.
The ultraviolet LEDs 102 are arranged at both end corners of the upper case, both end corners of the lower case, and a bottom surface of the case to radiate ultraviolet light from the front surface, the rear surface, and the bottom surface of the case 101. In the embodiment of the present invention, 8 ultraviolet LEDs 102a are arranged at four corners of an upper case of a quadrangular form as a front surface of the case 101 and four corners of a lower case of a quadrangular form as a rear surface, and 1 ultraviolet LED 102b is arranged at a bottom surface of the case 101.
An insertion port 103 into which the rotation shaft 20 is inserted is formed in a side surface of the housing 101. One side of the rotation shaft lever 20 is provided to the toilet cover 4, and the other side is inserted into the insertion port 103 of the housing 101 to support the housing 101 and stably realize the hinge rotation of the housing 101.
One side of the hinge portion 104 is attached to the support 105, and the other side is hinge-coupled to the housing 101, thereby hinge-rotating the housing 101. The hinge 104 is configured such that an upper hinge plate and a lower hinge plate are fastened, and an inclination sensor 106 (see fig. 4) is incorporated in a space formed by fastening the two hinge plates. That is, the hinge portion 104 includes a hinge shaft portion 104-1 hinge-coupled by being inserted into a hinge hole 101-2 formed in a groove 101-1 of the housing 101 and a support body coupling portion 104-2 extending to the hinge shaft portion 104-1 to be attached to the support body 105.
The support body 105 of the support body coupling part 104-2 to which the hinge part 104 is attached may be attached to the toilet cover 4 by means of an adhesive or fastened to the toilet cover 4 by a bolt/nut combination so as to be detachable for cleaning.
When the toilet cover 4 is opened, the housing 101 constituting the main body of the toilet sterilization device 10 is in contact with the inner wall of the toilet cover 4. The thickness of the housing 101 according to the present invention is almost equal to or less than the inner side thickness of the toilet cover 4, and thus the protruding feeling is not strong, and when a user is seated on the toilet seat 3 to relieve his/her hands, there hardly occurs a problem that the back of the user contacts the toilet sterilizing device 10, causing inconvenience.
In a state where the toilet cover 4 is opened, the ultraviolet LED 102 of the toilet sterilization device 10 does not emit light.
When the toilet cover 4 is closed, the housing 101 is rotated by an angle corresponding to the closing angle of the toilet cover 4 according to the rotation axis of the hinge shaft portion 104-1 of the hinge portion 104, so as to be spaced apart from the inner wall of the toilet cover 4 and enter the toilet bowl chamber 2. That is, when the user releases his/her hand and closes the toilet cover 4, the toilet cover 4 descends downward, and the housing 101 rotates according to the rotation axis of the hinge 104 by the internal load.
Referring to fig. 3 (a), it can be seen that when the toilet cover 4 is half-closed, the housing 101 rotates by an angle corresponding to the half-closed while maintaining the same gravitational direction as that in a state where the toilet cover 4 is in contact with the inner wall of the toilet cover 4 when the toilet cover 4 is opened.
Next, as shown in fig. 3 (b), when the toilet cover 4 is completely closed, the housing 101 is further rotated by an angle corresponding to the remaining angle while continuing to maintain the gravity direction and is perpendicular with respect to the inner wall of the toilet cover 4. As described above, the toilet sterilization device 10 is rotated about 90 degrees from the initial position to be in a state of being perpendicular to the inner wall of the toilet cover 4 and is suspended in the lateral direction in the toilet chamber 2.
If the toilet sterilization device 10 hangs in the longitudinal direction in the toilet chamber 2, the ultraviolet irradiation range is widened in the up-down direction, so that the sterilization effect can be increased.
The irradiation range of Ultraviolet (UV) LEDs generally reaches 120 ° to 160 ° in the up-down, left-right direction. In particular, in the present invention, 4 ultraviolet LEDs 102a respectively located at the front and rear surfaces of the housing 101 are located 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 ultraviolet irradiation range of the conventional product is limited, but as shown in (b), in the toilet sterilization apparatus 10 according to the present invention, 4 ultraviolet LEDs 102a respectively disposed at the front and rear surfaces of the housing 101 sterilize the upper and lower portions of the toilet seat and the RIM (RIM) 5 (the portion of the toilet bowl where water of the toilet bowl falls into the toilet room). The ultraviolet LED 102b disposed at the bottom surface of the housing 101 sterilizes even the water inside the toilet chamber 2.
Fig. 4 illustrates an internal configuration of a toilet sterilization device according to an embodiment of the present invention.
Referring to fig. 4, the toilet sterilization device 10 includes a housing 101 and a hinge 104, wherein a battery, an ultraviolet LED 102, a control unit 107, and the like are incorporated in the housing 101, and an inclination sensor 106 is incorporated in the hinge 104.
In addition, as another embodiment, in addition to the battery, the ultraviolet LED 102, and the control section 107, in the case where the housing 101 is built with a motion sensor, the hinge section 104 does not need a separate inclination sensor 106.
When the toilet cover 4 is opened or closed, the housing 101 is rotated by the hinge to always maintain the position in the gravity direction, so that there is almost no change in inclination, and conversely, the hinge portion 104 is rotated actually to change in inclination. Accordingly, the inclination sensor 106 for sensing the inclination change of the hinge portion 104 is built in the hinge portion 104. In an embodiment of the present invention, the inclination sensor 106 may be built in the support body connection part 104-2 of the hinge part 104.
The control section 107 periodically receives a sensing signal from the inclination sensor 106 to sense the rotation of the hinge section 104. The control section 107 processes the sensing signal and recognizes that the toilet cover 4 is closed when the rotation amount of the hinge section 104 is a threshold value (for example, 80 degrees to 90 degrees) or more, thereby operating the ultraviolet LED 102.
When it is determined that the toilet cover 4 is closed, the control part 107 operates the ultraviolet LED 102 to perform a sterilization operation after a predetermined time. The ultraviolet irradiation may be performed during a set time, or may be performed continuously or periodically. The ultraviolet LED 102 emits ultraviolet light to kill harmful bacteria present in the toilet bowl.
During the irradiation of the ultraviolet rays in the state where the toilet cover 4 is closed, if the user opens the toilet cover 4, the control part 107 may sense that the rotation amount of the hinge part 104 is reduced according to the sensing signal of the inclination sensor 106, thereby interrupting the irradiation of the ultraviolet LED 102.
Although fig. 4 shows a configuration in which the inclination sensor 106 is incorporated in the hinge 104, the inclination sensor 106 may be incorporated in the housing 101 instead of the hinge 104.
In this case, the control section 107 senses the positional movement of the housing 101 by periodically receiving a sensing signal from the motion sensing sensor. If the control part 107 senses the positional movement of the housing 101 by processing the sensing signal, it recognizes that the toilet cover 4 is closed, thereby operating the ultraviolet LED 102. As the motion sensor, a hall sensor may be used, and a magnet is attached to a portion of the toilet cover 4 that contacts the housing 101 so that the hall sensor senses magnetic force.
In this case, the magnet may be provided in the upper end of the hinge 104, that is, in a portion where the magnet is attached to the support 105. This is because, when the housing 101 rotates according to the rotation axis of the hinge portion 104, the housing 101 approaches or separates from the upper end of the hinge portion 104. At this time, a motion sensor (hall sensor) built in the housing 101 may be provided at a portion distant from or close to the upper end of the hinge portion 104.
The above detailed description is to be construed in all aspects as illustrative and not restrictive. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all change which comes within the equivalent scope of the invention are included in the invention.
