Description

Technology Field

[0001] The present invention relates to an integrated toilet seat cover having an automatic ultraviolet sterilization device, and more specifically, to an integrated toilet seat cover having an automatic ultraviolet sterilization device that allows the toilet seat to be sterilized with ultraviolet light together with the interior of the toilet body by installing a plurality of ultraviolet LED modules in a zigzag pattern on the bottom surface of the toilet seat cover. Background Technology

[0002] Generally, a toilet refers to a Western-style toilet designed for urinating and defecating while sitting, also known as a seated toilet or a flush toilet. A toilet typically comprises a toilet body with an oval-shaped receiving space formed at the top, a water tank installed on one side of the top of the toilet body with a flush handle rotatably installed on one side to supply stored water to the toilet body, and a toilet seat and toilet seat cover installed rotatably on one side of the top surface of the toilet body to open and close the receiving space.

[0003] These toilets allow for more hygienic and comfortable urination through the toilet seat. However, since this seat comes into direct contact with the human body and is designed for repeated use, it is difficult to maintain its hygienic condition in public restrooms used by many people.

[0004] In this regard, conventionally, disposable paper wraps that cover the toilet seat are installed in a replaceable manner, but even in such cases, it is not easy for the user to replace the disposable wrap every time it is used, and the toilet becomes dirtier due to the disposable wraps that are disposed of.

[0005] In addition, Western-style toilets have the advantage of being very convenient compared to traditional squat toilets because one sits on them to relieve oneself. However, even if one flushes the toilet after use, there are problems such as various parasites or pathogens discharged along with the waste remaining on the inner walls of the toilet bowl and in the stagnant water, and the remaining pathogens potentially infecting the user, making it very unsanitary.

[0006] Accordingly, a hygienic toilet has been researched and developed in the past. The "toilet water sterilization device for a direct-flow toilet" of Patent Document 1 comprises a direct-flow pipe that supplies toilet water to a direct-flow toilet, an electrolyte supply unit installed on the outside of the direct-flow pipe and introducing an electrolyte into the direct-flow pipe, and a mechanical dosing unit formed and installed on one or both sides of the outside of the direct-flow pipe, which opens and closes according to changes in the flow rate or pressure of the toilet water supplied to the direct-flow toilet as the direct-flow toilet is used, thereby supplying an electrolyte from the electrolyte supply unit onto the direct-flow pipe. By electrolyzing the toilet water through the supply of an electrolyte as the direct-flow toilet is used, the direct-flow toilet is configured to sterilize the direct-flow toilet without a water tank.

[0007] In addition, the "toilet sterilization device" of Patent Document 2 comprises a through hole penetrating the bottom plate of a bidet, a lower housing mounted such that the end of the lower body, through which a coupling hole penetrates the through hole, faces the inside of the toilet, an impeller nozzle body that is seated on the lower body while the nozzle body is coupled so that the discharge hole protrudes further through the coupling hole of the lower housing, and the nozzle body rotates by the sterilization water supplied from the sterilization water generating unit and sprays sterilization water through the discharge hole, an upper housing that is mounted on the lower housing to accommodate the impeller nozzle body and connected to the sterilization water generating unit, and a fixing bolt that fixes the upper and lower housings to the bottom plate of the bidet.

[0008] In addition, the "toilet sterilization device" of Patent Document 3 comprises a steam generating means provided inside the body of a bidet, a nozzle body mounted on the bidet body facing the inside of the toilet bowl and connected to the steam generating means and a steam supply line, and a steam nozzle means including a nozzle tip that is arranged to move back and forth inside the nozzle body, is provided with steam discharge holes, and sterilizes the inside of the toilet bowl with steam.

[0009] In addition, the toilet having a washing and sterilization function according to Patent Document 4 comprises a toilet cover in which steam or electrolytic water is introduced into the interior from a steam / electrolytic water supply unit and sprayed through a nozzle installed along the inner outer periphery, and simultaneously sprayed through a nozzle installed in a protrusion formed in the center, a toilet seat in which steam or electrolytic water is introduced into the interior from a steam / electrolytic water supply unit and sprayed through a nozzle installed along the inner periphery, and a water tank washing unit that receives steam or electrolytic water from a steam / electrolytic water supply unit and sprays it into the water tank.

[0010] However, the aforementioned conventional technologies have a limitation in that they cannot sterilize the inside of the toilet bowl along with the toilet seat in contact with the body at the same time. In addition, there is a problem in that installation and maintenance are difficult due to the very complex structure. Prior art literature
