Description

Technology Field

[0001] The present invention relates to a sterilization and cleaning device for a urinal, and more specifically, to a sterilization and cleaning device for a urinal that maximizes cleaning power by adding a cleaning agent to the cleaning water flowing down the wall from the top of the urinal, and simultaneously suppresses the generation of odors from the urinal by exerting sterilization power through the emission of ultraviolet rays to the exposed surfaces (wall and floor surfaces) where urine comes into contact. Background Technology

[0003] A restroom is a space where people perform physiological activities, such as relieving themselves or washing their hands, at least once a day; it has established itself as an essential architectural structure in human society to the extent that it is installed in every building related to humans.

[0004] Furthermore, as society entered the industrial era and cities were formed, the need arose for places to relieve physiological needs outside the home, leading to the installation of public toilets available for anyone to use.

[0005] Meanwhile, restrooms, which are the most frequently used spaces among the amenities at rest areas on highways as well as on each floor of buildings, are mostly divided into men's and women's restrooms, and urinals are typically installed in men's restrooms. This is because urination is usually more frequent than defecation, and unlike toilets that require individual partitions, urinals can be installed more frequently in the same area, allowing for better space utilization and increasing the turnover rate of restroom use.

[0006] Supporting this, the number of men's toilets in public restrooms in Korea in 2020 was tallied at approximately 366,879, of which 22,000, or 60%, were men's urinals (data on the status of public restrooms in Korea by the Ministry of the Interior and Safety). Furthermore, as the number of restrooms has increased since local governments were granted autonomy regarding the installation of public restrooms starting in September 2019, the installation of men's urinals has also expanded significantly.

[0007] However, according to a public restroom user satisfaction survey conducted by the Korea Toilet Association (KTA) in 2019, 23% of the total 258 respondents reported feeling inconvenienced by restrooms that were not properly maintained or repaired.

[0008] To elaborate, in addition to the structural characteristics of urinals installed in men's restrooms within the aforementioned public restrooms at highway rest areas and the behavioral characteristics of men urinating using them, the occurrence of foul odors caused by ammonia components adhering to the exposed surfaces (walls and floors where urine comes into contact) of the urinals is causing discomfort to users due to the relatively infrequent cleaning compared to the high frequency of use.

[0009] Consequently, ventilation fans have been installed to circulate the indoor air of restrooms using a forced ventilation method as a measure to maintain the cleanliness of men's urinals; however, since the odors generated from the urinals are exhausted only after they have already contaminated the indoor air, the problem of odor generation from the urinals cannot be resolved, and there has been a problem of significantly reduced heating and cooling efficiency due to the use of the fans.

[0010] As an alternative, naphthalene deodorizers are used by hanging them above the urinal or placing them on the floor; however, not only are they unable to completely eliminate the foul odor emanating from the urinal, but naphthalene also poses problems such as environmental pollution and the release of harmful substances detrimental to the human body upon contact with urine.

[0011] In order to solve these problems, a urinal scent cleaning device has been disclosed in Korean Patent Publication No. 10-2007-0010481, which enables cleaning of the urinal by allowing water (hereinafter referred to as "cleaning water") flowing down the wall from the top of the urinal to flow down together with a scent cleaning agent.

[0012] FIG. 1 is an exploded view of a directional urinal cleaning device according to the prior art, and FIG. 2 is a view of the usage state of a directional urinal cleaning device according to the prior art. The urinal cleaning device (900) according to the prior art is composed of: a main body (901) positioned on the upper side of the wall of a urinal (B) as shown in FIG. 1 and FIG. 2; a cleaning container (902) provided inside the main body (901) and capable of storing and replacing a directional cleaning agent; and a discharge device connecting plate (903) provided at the lower part of the cleaning container (902) inside the main body (901) and controlling the volume of the directional cleaning agent.

[0013] According to the prior art, cleaning water automatically discharged from the top of the urinal (B) based on sensor operation that detects the user's withdrawal (movement) from the urinal (B) passes through the main body (901) and flows down the wall of the urinal (B) together with the fragrance cleaning agent in the cleaning container (902), thereby providing the effect of cleaning the urinal (B) as well as removing the odor.

[0014] However, even setting aside the inconvenience of having to detach / attach the cleaning container (902) from the main body (901) for the purpose of replenishing the cleaning agent when the cleaning agent in the cleaning container (902) is depleted, the task of detaching the cleaning container (902) from the main body (901), which has been contaminated by prolonged use in the urinal (B), by the worker's own hand is bound to be very difficult.

[0015] In addition, there is a problem of deterioration in product competitiveness due to increased manufacturing costs and rising product unit prices caused by the complexity of components such as the main body (901), cleaning container (902), discharge device connecting plate (903), and the fixing plate (911) connected to the rear of the main body (901).

[0016] In addition, there is a problem of reduced installation efficiency in that the fixing plate (911) of the main body (901) must be attached to the wall of the urinal (B) using separate double-sided tape, and there is a problem that if the device is installed in the urinal (B) for a long time, the adhesive strength of the double-sided tape decreases due to contact with liquids such as urine or cleaning fluid, causing the device to detach and fall off from the urinal (B).

[0017] In addition, the fixing plate (911) must be bent and deformed to correspond to the curvature of the wall of the urinal (B). Even setting aside the inconvenience of this process, it is not easy to deform the fixing plate (911) to match the curvature of the wall of the urinal (B), and this has exacerbated the problems of reduced adhesive strength of the double-sided tape and the resulting detachment and falling of the device.

[0018] Ultimately, there is an urgent need for research and development of a sterilization and cleaning device for urinals that can not only sterilize and clean the urinal but also further enhance the convenience of replacing the cleaning agent, while simultaneously satisfying the ease of installation and robustness in response to various curvatures of the urinal walls.

Specific details for implementing the invention

[0038] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings so that a person skilled in the art can easily practice the present invention.

[0039] First, it should be noted that when assigning reference numerals to the components of the drawings, identical components are assigned the same reference numeral whenever possible, even if they are shown in different drawings. Additionally, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0040] Figures 3 to 5 of the attached drawings are a perspective view, an exploded perspective view, and a side cross-sectional view showing the configuration of a sterilization and cleaning device for a urinal according to the present invention, and Figure 6 is a cross-sectional view of a key part showing the operation form of a detachable means in a sterilization and cleaning device for a urinal according to the present invention.

[0041] As illustrated in FIGS. 3 to 5, the sterilization and cleaning device (A) for a urinal according to the present invention comprises a main body (1) that accommodates a cleaning means to be described later, a detachable means (2) that has one side fixed to the upper part of the wall surface (B-1) among the exposed surfaces (wall and floor surfaces where urine touches) of the urinal (B) and is mounted on the opposite side of the main body (1), a cleaning means (3) that is in contact with the wall surface (B-1) of the urinal (B) while being accommodated in the main body (1) so as to allow for the mixing of components into the cleaning water flowing down the wall surface (B-1) from the top of the urinal (B), and a sterilization means (4) provided in the main body (1) to emit ultraviolet rays to the exposed surface of the urinal (B).

[0042] The main body (1) is formed in the shape of a box with an internal space (1a) and an additional component (electronic device) necessary for device operation (sterilization means) based on detection of the approach of a user of the urinal (B), in addition to the provision of the cleaning means (3) and the sterilization means (4). On one side facing the urinal (B), a space (11a) for the cleaning means (3) is provided, and at the same time, an inclined end (11) is formed so that the cleaning means (3) can be in close contact with the wall of the urinal (B).

[0043] In addition, one or more metal plates (12) that are joined to the magnet provided in the detachable means (2), which will be described later, are embedded in the lower end of the inclined portion (11), and a control module (13) necessary for operating the device is built into the internal space (1a).

[0044] Here, the control module (13) is a printed circuit board that receives power to operate the sterilization means (4), and may further include a sensing sensor (131) that detects the approach and movement of a user, a battery (not shown), an external power connection, and a connection port (not shown) for charging the battery.

[0045] The above battery may be a battery that can be replaced after a certain period of time, or a conventional rechargeable battery that can store a certain amount of power and supply the stored power.

[0046] The attachment / detachment means (2) is configured to allow the main body (1) to be easily attached / detached from the wall surface (B-1) of the urinal (B) by utilizing the principle of gas pressure and comprises a plurality of vacuum pressers (21) that are pressed against the wall surface (B-1) of the urinal (B), and a base plate (22) on which the main body (1) is mounted in the center and which is integrally assembled with the vacuum pressers (21) on each side.

[0047] The above vacuum press (21) comprises a press pad (211) that is vacuum-bonded to the wall (B-1) of the urinal (B), a base hood (212) provided on one side of the press pad (211) and presses the edge of the press pad (211) to firmly secure the bond, and a dial knob (213) that forms a connection between the press pad (211) and the base hood (212) to one side of the base plate (22), and adjusts the vacuum pressure in the space between the press pad (211) and the wall (B-1) by changing the shape of the press pad (211) according to user operation in a clockwise / counterclockwise direction.

[0048] Additionally, a link bolt (211-1) is protruded from the center of one side of the compression pad (211) to penetrate the base hood (212) and screw-couple to the dial knob (213), thereby causing a deformation of the compression pad (211) when the dial knob (213) is operated by the user.

[0049] The above base plate (22) is composed of a crossbar (221) for mounting the main body (1) and fixing the position of the attachment / detachment means (2), and a pivot ring (222) capable of left and right horizontal rotation for adjusting the orientation angle of the attachment / detachment means (2), each provided on both sides of the crossbar (221).

[0050] Additionally, the crossbar (221) has a main body joint (221-1) on which the main body (1) is mounted, and on both sides of the main body joint (221-1), a compression joint (221-2) on which the detachable means (2) is assembled.

[0051] And, at a designated location of the main body joining part (221-1), one or more magnets (221-11) are embedded to magnetically attract one or more metal plates (12) embedded in one end of the main body (1) to form mutual joining.

[0052] Additionally, a receiving hole (221-21) is formed through the central part of the above-mentioned presser coupling part (221-2) to receive a rotating ring (222) and not interfere with the rotational movement of the rotating ring (222), and a hinge hole (221-22) for inserting a hinge projection of the above-mentioned rotating ring (222), which will be described later, is formed in the upper and lower parts of the above-mentioned receiving hole (221-21).

[0053] And, in the above-mentioned pivot ring (222), a hinge projection (222-1) that forms an axial rotation while inserted into each of the above-mentioned hinge holes (221-22) is protruded at the upper and lower ends, and a coupling hole (222-2) that is threaded through the center to allow the link bolt (211-1) of the above-mentioned compression pad (211) to pass through and be screw-coupled to the above-mentioned dial knob (213).

[0054] The cleaning means (3) is intended to maximize the cleaning power of the urinal (B) by adding a cleaning agent component to the cleaning water flowing down the wall (B-1) from the top of the urinal (B), and can be formed and manufactured in various forms such as a bar or ball made of a large amount of zeolite or ceramic component or a combination of these components so that negative ions can be added to the cleaning water. In addition, it is desirable that it can simultaneously possess the functionality of emitting a fragrance as well as the cleaning mentioned above.

[0055] The sterilization means (4) is for sterilizing and disinfecting the urinal (B) through the emission of ultraviolet rays, and is preferably a lamp that emits UV-C (ultraviolet-C) ultraviolet rays with a range of 200~280 nm, which is an environmentally friendly light that does not contain chemicals or mercury, sterilizes 99.9% of bacteria or viruses, and damages the molecular structure of bacteria DNA and RNA so that bacteria cannot multiply.

[0056] The operation of the sterilization and cleaning device (A) for a urinal according to the present invention, configured as described above, is specifically explained as follows.

[0057] First, FIG. 7 is a usage state diagram showing the installation relationship of a sterilization and cleaning device for a urinal according to the present invention, FIG. 8 is an exemplary cross-sectional view showing the flow relationship of the cleaning water and the light emission form of the sterilization means in the sterilization and cleaning device for a urinal according to the present invention, FIG. 9a and FIG. 9b are exemplary plan views showing the orientation angle adjustment state of the attachment and detachment means in the sterilization and cleaning device for a urinal according to the present invention, and the sterilization and cleaning device (A) for a urinal according to the present invention can be installed and used on the upper part of the wall surface (B-1) of the urinal (B) for the purpose of cleaning and sterilizing the male urinal (B), as shown in FIG. 7.

[0058] Specifically, by pressing the vacuum pressers (21) attached to both sides of the base plate (22) against the wall (B-1) while the attachment means (2) is positioned close to the upper side of the wall (B-1) of the urinal (B), the installation state of the attachment means (2) attached to the wall (B-1) is firmly maintained.

[0059] This can be achieved by rotating the dial knob (213) of the vacuum presser (21) while the compression pad (211) of the vacuum presser (21) is in close contact with the wall (B-1), thereby deforming the compression pad (211) and increasing the vacuum pressure in the space between the compression pad (211) and the wall (B-1) accordingly.

[0060] Furthermore, the main body (1) is mounted on the base plate (22) of the above-mentioned attachment means (2), and the magnet (221-11) embedded in the main body joining part (221-1) provided in the center of the crossbar (221) of the above-mentioned base plate (22) magnetically attracts the metal plate (12) embedded in the main body (1) to form a mutual joining, which can be done by referring to FIG. 8.

[0061] Next, a cleaning means (3) is housed in the receiving space (11a) of the main body (1). When the cleaning means (3) is housed in the receiving space (11a), the cleaning means (3) can be in close contact with the wall surface (B-1) of the urinal (B) due to the influence of the inclined end (11) formed on one side of the main body (1) to provide the receiving space (11a). As a result, the cleaning water that flows down the wall surface (B-1) after being discharged from the top of the urinal (B) passes through the cleaning means (3) and contains a cleaning agent, and the cleaning power can be maximized across the entire exposed surface of the urinal (B) by the cleaning water mixed with the cleaning agent.

[0062] In addition, a control module (13) that receives a signal (movement of the user) from a sensing sensor (131) provided in the main body (1) operates a sterilization means (4) according to a preset program to emit ultraviolet rays from the sterilization means (4), and as the ultraviolet rays emitted from the sterilization means (4) to the lower side of the main body (1) are irradiated throughout the urinal (B), the urinal (B) is sterilized and disinfected, thereby minimizing the generation of bad odors from the urinal (B).

[0063] Meanwhile, the curvature of the wall surface (B-1) of the above urinal (B) may vary, and as shown in FIG. 9a and FIG. 9b, a firm compression of the attachment / detachment means (2) corresponding to the curvature of the wall surface (B-1) is possible by adjusting the orientation angle of the vacuum compression device (21).

[0064] In detail, the dial knob (213) among the components of the vacuum presser (21) of the above-mentioned attachment / detachment means (2) can be operated so that the orientation angle of the above-mentioned presser pad (211) is parallel to the curvature of the wall surface (B-1) of the above-mentioned urinal (B). This change in the orientation angle of the above-mentioned presser pad (211) is made possible by the horizontal rotation of the pivot ring (222) which is provided and coupled in a horizontally rotatable state in the center of the presser coupling part (221-2) of the above-mentioned base plate (22). The pivot ring (222) follows the axial rotation of the hinge protrusions (222-1) that protrude from the upper and lower parts and are inserted into the hinge holes (221-22) formed in the upper and lower parts of the receiving hole (221-21) that penetrates the center of the above-mentioned presser coupling part (221-2).

[0065] In summary, according to the sterilization and cleaning device (A) for a urinal of the present invention, the cleaning water that flows down along the wall (B-1) after being discharged from the top of the urinal (B) passes through the cleaning means (3) provided in the main body (1), and as the cleaning agent component of the cleaning means (3) is mixed in, the effect of greatly increasing the cleaning power of the urinal (B) using the cleaning water can be achieved.

[0066] In addition, sterilization and disinfection are performed throughout the urinal (B) by means of a sterilization means (4) that emits ultraviolet rays downward from the main body (1), thereby minimizing the generation of bad odors from the urinal (B) contaminated with urine, while simultaneously maintaining the cleanliness of the toilet and the comfort of use through the visual effect of the ultraviolet rays.

[0067] In addition, by adjusting the directional angle of the vacuum presser (21) using the pivot ring (222) provided on the base plate (22) of the detachable means (2), the effect of simultaneously satisfying ease of installation and robustness that corresponds to the curvature of the wall surface (B-1) of the urinal (B) can be achieved.
