Description

Sterilization cover for toilet

The present invention relates to a sterilization cover for a toilet seat, and more particularly, it sterilizes harmful bacteria attached to the toilet bowl through sterilization ultraviolet rays to enable clean hygiene management of the toilet bowl, but in particular, a square in which ultraviolet rays for sterilization do not reach It relates to a sterilization cover for a toilet that can maximize sterilization efficiency by uniformly irradiating even the zone.

Toilet bowls, which are frequently used in daily life, can be a breeding ground for various pathogens including E. coli, and there is a problem that there are many concerns that they may act as a medium through which skin diseases or infectious diseases can be transmitted.

Mainly, secondary infection occurs due to the flush lever (or button) in the process of flushing the toilet after toilet. If you flush the toilet without covering the toilet lid after going to the toilet, the moment you flush the toilet, the bacteria that have formed near the surface of the toilet spread all over the place.

This problem appears more prominently in the public toilet toilet used by an unspecified number of people for common use. Because it is easily contaminated, there is a limit to keeping the toilet clean even with periodic cleaning.

Accordingly, techniques that can effectively sterilize harmful bacteria around the toilet without a physical cleaning process of the toilet have been proposed. The contents are introduced as follows.

The prior document discloses a toilet sterilization device for sterilizing a toilet comprising a toilet body and a toilet seat provided on the upper end of the toilet body to form a saddle, which is hinged to the toilet body and rotates about a hinge axis while rotating the toilet seat. a seat cover that covers or opens; a sterilization lamp installed along the inner circumferential surface of the seat cover and turned on and off by opening and closing of the seat cover while facing the surface of the toilet seat, and irradiating ultraviolet rays to the surface of the toilet seat to sterilize the surface of the toilet seat; and a sterilization controller for controlling the operation of the sterilization lamp while supplying power to the sterilization lamp.

That is, the prior art is a method of sterilizing harmful bacteria in the toilet seat with light irradiated from an ultraviolet sterilization lamp mounted on the seat cover.

However, in the case of the prior art, since the sterilization lamp is located directly above the toilet seat, a structural problem follows that the sterilization lamp forms a blind spot that the sterilization lamp cannot reach.

That is, the sterilizing light must be irradiated to the overall area of the toilet seat, but there is a problem in that the sterilizing light does not reach a specific portion, for example, both sides of the toilet seat and also the water tank wall portion of the toilet body, thereby reducing the sterilization efficiency.

Due to this problem, the prior art is configured to further include a toilet sterilization unit that is configured separately from the sterilization lamp and is additionally installed in the center of the seat cover. acts as a factor that reduces the effectiveness of

The present invention was created to solve the problems in the prior art in consideration of the above problems. It sterilizes harmful bacteria attached to the toilet bowl through sterilizing ultraviolet rays to enable clean and hygienic management of the toilet bowl, and in particular, sterilizing ultraviolet rays An object of the present invention is to provide a sterilization cover for a toilet bowl that can maximize sterilization efficiency by uniformly irradiating even blind spots that cannot be reached.

The present invention is a means for achieving the above object, the sheet portion; a cover portion rotatably installed at the rear end of the seat portion so as to selectively cover the upper surface of the seat portion; and a sterilization unit formed on the lower surface of the cover unit and irradiating a sterilizing light to the lower side of the cover unit in a closed state of the cover unit. The sterilization unit may include: a mounting cover having a mounting member protruding downward, a side surface of the mounting member is inclined at a certain angle inward toward the lower side, and a plurality of first mounting grooves are provided along the side surface; a plurality of UV light sources installed in each of the plurality of first mounting grooves; and a reflector formed on the wall surface of each of the plurality of first mounting grooves to reflect the sterilizing light irradiated from the UV light source.

In addition, it is characterized in that a support protrusion supported on the upper surface of the toilet body by passing through the front of the seat portion in the closed state is formed in the front of the cover portion.

In addition, it is characterized in that a handle for rotating the cover part is formed around the cover part.

In addition, the first mounting groove is characterized in that the opening area is gradually expanded toward the top of the opening.

The present invention provides the following effects.

First, since the UV light source is installed on the side of the mounting member inclined at a certain angle, the UV light source can irradiate the sterilizing light to the seat portion in a state inclined at a certain angle according to the inclination angle of the side of the mounting member. As a result, since the sterilizing light is irradiated diagonally toward the surface of the sheet part, it is possible to prevent the occurrence of a blind spot where the sterilizing light does not reach, and it is possible to irradiate the sterilizing light over the entire area of the seat part.

Second, since the UV light source is installed at an angle according to the inclination angle of the side of the mounting member, it has a structure in which water droplets splashing out of the water tank cannot easily attach to the UV light source at the moment of flushing the toilet. It is equipped with a structure in which splashed water drops can easily fall freely due to their own weight.

Third, it is possible to maximize the irradiation area of the sterilizing light by configuring the first mounting groove to gradually expand the opening area toward the top of the opening.

Fourth, the sterilization light irradiated from the UV light source through the reflector is reflected toward the sheet portion so that the sterilization light can have a wide irradiation range, thereby increasing the sterilization efficiency, as well as absorbing the heat generated from the light source so that the mounting cover is heated. deformation can be prevented.

This example is provided to more completely explain the present invention to those of ordinary skill in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations determined to unnecessarily obscure the gist of the present invention will be omitted.

Prior to the description of the invention, if a non-strict direction reference is specified with reference to the accompanying drawings for convenience of explanation, the vertical (y), left and right (x), and front and rear (z) In the description related to the division and other drawings, the direction standard is specified according to this standard.

The toilet seat according to the present invention is a cover rotatably installed at the rear end of the seat unit 100 to selectively cover the seat unit 100 and the upper surface of the seat unit 100, as shown in FIGS. 1 to 3 . It may be defined as including the sterilization unit 300 formed on the lower surface of the unit 200 and the cover unit 200 and irradiating sterilizing light downward of the cover unit 200 in the closed state of the cover unit 200 . .

1 is a view showing the closed state of the sterilization cover according to the present invention, Figure 2 is a view showing the open state of the sterilization cover according to the present invention, as shown in FIG. A state in which the water tank of the toilet body 1 is closed by covering 100 is referred to as a closed state, and as shown in FIG. 2 , the cover 200 is rotated upward to open the water tank of the toilet body 1 . is defined as an open state.

Unexplained reference numeral 1 shown in the drawings indicates the toilet body 1, and the specific configuration of the sterilization cover will be described based on the use state in which the toilet body 1 is equipped with the sterilization cover.

First, the seat part 100 is a part for supporting the user's buttocks when the user is seated, and may be understood as a configuration corresponding to a horseshoe-shaped seat installed in a normal toilet.

In this embodiment, although the seat part 100 is included as the main component of the sterilization sheet, the seat part 100 can use the toilet seat installed in the existing toilet body 1 as it is, in this case, the cover part 200 and It is revealed that only the configuration of the sterilization unit 300 can be additionally mounted to the toilet body 1 .

The cover part 200 may be formed in a wide plate shape that can cover not only the seat part 100 but also the water tank of the toilet body 1 when in a closed state.

The cover unit 200 may have a structure that sufficiently covers the side surface so that the sterilizing light irradiated from the sterilization unit 300 does not leak to the outside when the sterilization mode of the sterilization unit 300 is executed.

When the cover part 200 is closed, the cover part 200 has a structure for covering the seat part 100 while being spaced apart from the seat part 100 by a certain distance, and in particular, the cover part 200 is the seat part 100 ) so as not to form a separate contact point to have a structure in which sterilizing light can be irradiated over the entire surface of the sheet part 100 .

To this end, a support protrusion 210 that passes through the front of the seat unit 100 and is supported on the upper surface of the toilet body 1 may protrude from the front of the cover unit 200 .

Since the support protrusion 210 formed in the front of the cover part 200 is supported on the upper surface of the toilet body 1 in the closed state of the cover part 200 , the cover part 200 is fixed on the upper part of the seat part 100 . It becomes a structure that can cover the sheet part 100 in a spaced apart state.

As shown in FIG. 4 , the seat part 100 is usually formed in the shape of a horse's hoof, and the segmented portion 110 is formed in the front. Since it is supported on the cover 200 , it may be covered on the upper surface of the seat part 100 in a state in which the cover part 200 does not contact the seat part 100 .

That is, since the cover part 200 does not form a separate contact point on the seat part 100 when the cover part 200 is in a closed state, it is possible to prevent the seat part 100 from being covered by the cover part 200 . And, through this, the sterilizing light may be irradiated to the entire portion of the sheet unit 100 .

If the cover part 200 is supported by the seat part 100 when the cover part 200 is in a closed state, contact formation with the cover part 200 is unavoidable in the seat part 100, and sterilizing light is applied to the contact part. This is not reached, and there is a problem in that an unsterilized portion is partially generated in the seat portion 100 .

A handle 220 for rotating the cover unit 200 may be formed around the cover unit 200 , and the user may hold the handle 220 by hand to rotate the cover unit 200 . .

An operation button 230 of the sterilization unit 300 and a status indicator light 240 indicating an operating state of the sterilization unit 300 may be formed on the upper surface of the cover unit 200 .

The status indicator 240 can be roughly divided into a constant power light and a working light, and in particular, the operating light has a configuration that is lit only in a state in which the UV light source 320 is operated, or is configured to be lit with a light of a different color can be

For example, when the user presses the operation button once, the UV light source 320 is operated for a preset time, and in conjunction with this, the operation lamp is turned on or a light of another color is turned on, and the operation of the UV light source 320 is stopped. In connection with this, the operating light can be turned off or converted to the original color light.

Through this, the user can visually check the sterilization status of the toilet, even if the user does not operate the cover part 300 in an open state.

Next, the sterilization unit 300 may be mounted on the lower portion of the cover unit 200 to be rotated in conjunction with the cover unit 200 when the cover unit 200 is rotated. In particular, the sterilization unit 300 is set to operate only in the closed state of the cover unit 200 to prevent the sterilization light from being exposed to the outside. To this end, it may include a sensor for detecting the opening/closing operation of the cover unit 200, and may have a configuration in which the sterilization unit 300 is selectively operated and controlled based on the detection signal of the sensor, and the cover unit (without a separate sensor) ( 200) may be configured to detect a closed state through a switching action in which the circuit is electrically opened or shorted according to the rotation operation.

The sterilization unit 300 in this embodiment is configured so that sterilization light can be irradiated not only to the seat unit 100, but also to the toilet body 1 and the inside of the water tank to increase sterilization efficiency, and in particular, the seat unit 100 It has a structure that minimizes the occurrence of blind spots where the sterilizing light does not reach, so that the seat unit 100 can be managed more hygienically.

To this end, the sterilization unit 300 may be exemplified as largely including a mounting cover 310 , a UV light source 320 , and a reflector 330 .

First, the mounting cover 310 is mounted across the inner space of the cover unit 200, and supports the UV light source 320, the reflector 330, and the like. A sealed space may be formed between the mounting cover 310 and the cover part 200 by the mounting cover 310, and a PCB and various electrical devices may be embedded in the sealed space.

The mounting cover 310 is configured in the form of a wide plate, and in particular, may have a mounting member 311 protruding downward in the center.

The side surface of the mounting member 311 is inclined at a certain angle inward toward the lower side, and a plurality of first mounting grooves 311a may be provided along the side surface. A UV light source 320 may be installed in each of the plurality of first mounting grooves 311a.

That is, since the UV light source 320 is installed on the side of the mounting member 311 inclined at a certain angle, the UV light source 320 emits sterilizing light in a state inclined at a certain angle according to the inclination angle of the side of the mounting member 311 . The sheet part 100 may be irradiated.

In addition, since the UV light source 320 is installed inclined at a certain angle according to the side inclination angle of the mounting member 311, water droplets splashing out of the water tank at the moment of flushing the toilet cannot be easily attached to the UV light source 320. is equipped, as well as a structure in which water droplets splattered toward the UV light source 320 can easily fall freely due to their own weight.

The first mounting groove 311a is configured such that the opening area is gradually expanded toward the top of the opening so that the sterilizing light can have a wide irradiation angle. If necessary, a transparent window may be installed on the opening.

On the other hand, the mounting cover 310, as shown in FIG. 5, constitutes the outermost periphery of the mounting cover 310 and includes the peripheral member 312 and the mounting member 311 adjacent to the inner surface of the cover part 200 A connecting member 313 for connecting the peripheral member 312 may be further included. The mounting member 311 , the peripheral member 312 and the connecting member 313 constituting the mounting cover 310 may be integrally formed.

The peripheral member 312 may be formed in a shape symmetrical to the side surface of the mounting member 311 as shown in FIG. 9 , and the first mounting groove 311a formed on the side surface of the mounting member 311 is the same A mounting groove 312a may be formed. In addition, a first auxiliary light source 312b having the same function as the UV light source 320 may be installed in the first mounting groove 312a of the peripheral member 312 .

That is, since the sterilizing unit 300 irradiates the sterilizing light in the lower diagonal direction while facing each other on the upper portion of the sheet unit 100 , it is possible to prevent the occurrence of a portion where the sterilizing light does not reach, for example, a blind spot.

10 is a view exemplarily illustrating the arrangement structure of a UV light source, which inevitably causes blind spots in the prior art, and if, as shown in FIG. When irradiated, a blind spot Z may occur in the outermost lower periphery of the sheet portion 100, and a UV light source 320 directly above the sheet portion 100 as shown in FIG. 10b. When installed and irradiated with sterilizing light, there is a problem that a blind spot (Z) occurs not only around the outermost lower end of the seat unit 100 but also around the inner lower end.

The aforementioned UV light source 320 , the first auxiliary light source 312b , and the second and third auxiliary light sources to be described later may be made of a known UV LED module that can be turned on or off under the control of the operation button 230 , at this time , UV LED module can be roughly divided into UV-A (315~400nm) type, UV-B (280~315nm) type, UV-C (200~280nm) type, etc. 200~280nm) type is applied to air purification, water purification, and sterilization products.

That is, the light source in this embodiment may preferably be referenced from a UV-C type LED module.

Next, the reflector 330 is formed on the wall surface of each of the plurality of first mounting grooves 311a and 312a to reflect the sterilizing light irradiated from the UV light source 320 .

The reflector 330 reflects the sterilizing light irradiated from the UV light source 320 or the first auxiliary light source 312b toward the sheet portion 100 so that the sterilizing light has a wide irradiation range to increase sterilization efficiency. Of course, by absorbing heat generated from the light source, the mounting cover 310 functions to prevent thermal deformation.

On the other hand, in the present embodiment, it has a structure capable of sterilizing up to the upper end of the toilet body 1 disposed under the seat portion 100 .

In general, the importance of cleanliness is lowered in that the upper end of the toilet body 1 is mainly covered by the seat part 100 when in use, and it is a part that does not come in direct contact with the skin. Because it is covered by the sterilization light, there is a limit to hygienically managing it because it cannot easily reach the sterilizing light.

Moreover, the male mainly rotates the seat part 100 upward to completely open the upper surface of the toilet body 1 and then sees the business. Contamination occurs, and there are problems such as generation of odors, proliferation of harmful bacteria, and, in severe cases, adhesion of urinary stones from these contaminated parts.

Therefore, in this embodiment, as well as the cover part 200, it has a structure capable of sterilizing the upper end of the toilet body 1 and the wall surface of the tank widely.

To this end, as shown in FIG. 11 , a second mounting groove 211 may be formed on the rear surface of the support protrusion 210 , and a third mounting groove 212 may be recessed on the lower surface of the support protrusion 210 , respectively, and the second mounting groove 211 may be recessed. ), the second auxiliary light source 213 is installed to be inclined at a certain angle in the lower diagonal direction to irradiate the sterilizing light toward the rear wall of the water tank, and the third mounting groove 212 is irradiated with the sterilizing light directly downward to irradiate the toilet body (1). ) a third auxiliary light source 214 for sterilizing the upper surface may be installed.

As described above, the sterilizing light of the UV light source 320 or the first auxiliary light source 312b cannot be irradiated to the upper surface of the toilet body 1 covered by the seat unit 100, but the segmentation of the seat unit 100 The second auxiliary light source 213 and the third auxiliary light source 214 provided on the support protrusion 210 due to the structural characteristics of the support protrusion 210 passing through the portion 110 and making contact with the upper surface of the toilet body 1 are connected to the toilet bowl. Sufficient sterilizing light can be irradiated toward the upper surface of the main body 1 and the water tank.

Here, since the third auxiliary light source 214 irradiates sterilizing light directly below the point where the support protrusion 210 comes into contact with the upper surface of the toilet body 1, the toilet body 1 exposed by the segmented portion 110 It is possible to intensively sterilize the upper front portion of the water tank, and the second auxiliary light source 213 can intensively sterilize the rear wall portion 2 of the water tank including the water filled in the water tank.

In particular, since the rear jaw structure 3 for mounting the rear end of the seat part 100 is essentially formed on the rear side of the upper surface of the toilet body 1, the sterilizing light is emitted after the water tank, which is the lower structure of the rear jaw structure 3 . The wall area (2) could not be reached easily.

Accordingly, in this embodiment, since the sterilizing light is irradiated from the front to the rear of the water tank, the sterilizing light can be sufficiently irradiated up to the rear wall surface of the water tank 2 , and thus the clean management of the toilet body 1 is possible. provides table

On the other hand, the dotted line shown in FIGS. 9 to 11 may be understood as a portion exemplarily showing the irradiation range of the sterilizing light.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. Moreover, it is to be understood that the present invention covers all modifications, equivalents and substitutions falling within the spirit and scope of the invention as defined by the appended claims.
