For example, the mobile sterilizing device 1700 moving along the fourth straight rail 1600-4 may move the occupancy space 20-1 in response to determining that a human body is present in the occupancy space 20-1 through a detection sensor. 1) can be controlled to move out of the open space 10. Therefore, it is possible to sterilize the open space when a person is in the occupied space, and to perform sterilization of the occupied space when a person is not in the occupied space.

Figure 9 is an example of the arrangement of a circular rail. As shown in FIG. 9, for example, a circular rail 1600a-1 provides a circular movement path encompassing the occupied spaces 20-1, 20-2, and 20-3 and the open space 10, The mobile sterilization device 1700 may be configured to perform sterilization of occupied spaces and/or open spaces while moving along such a circular movement path.

In Figures 7 to 9, for convenience of explanation, the configuration according to the straight rail and the configuration according to the circular rail are explained separately, but the movement paths according to the mixed configuration of one or more straight rails and one or more circular rails are also shown. It should be understood as being included in the technical idea of the present invention.

Meanwhile, according to one aspect of the present invention, the control unit 1200 may be configured to control the mobile sterilizing device 1700 based on whether a human body exists inside the bathroom or the occupied space.

For example, the control unit 1200 may be configured to stop the movement of the mobile sterilizing device 1700 in response to the detection sensor unit 1100 detecting a human body. Some bathroom users may be averse to the mobile sterilizing device 1700 moving while using the restroom. Accordingly, the control unit 1200 may stop the movement of the mobile sterilizing device 1700 in response to detecting the presence of a human body inside the restroom. When the human body no longer exists, the mobile sterilization device 1700 can start moving again. Or, as previously mentioned in relation to FIG. 8, the presence of a user in the occupied space is detected, and if a user is present in the occupied space, the mobile sterilizing device 1700 is controlled not to move to the occupied space, However, the mobile sterilizing device 1700 may be configured to continuously move and perform sterilization in spaces where the user is not located.

According to one aspect, the control unit 1200 stops the operation of the surface sterilizing unit 1010 in response to the detection sensor unit 1100 detecting a human body, and the air sterilizing unit 1020 operates regardless of whether the human body is detected. It can also be controlled to operate. That is, the surface sterilizing unit 1010 may be configured to irradiate ultraviolet rays to the surface, which may affect the human body and cause discomfort to the user. Accordingly, when the control unit 1200 detects the presence of a human body, it can stop the operation of the surface sterilizing unit 1010 to minimize the impact on the human body and/or cause discomfort. On the other hand, the air sterilizing unit 1020 may be configured to irradiate ultraviolet rays to the photocatalyst present inside, so it may not have a direct effect on the human body. Accordingly, the control unit 1200 can control the air sterilizing unit 1020 to operate regardless of whether a human body is detected.

As discussed above, the comprehensive bathroom sterilization management system according to one aspect of the present invention is equipped with a mobile sterilization device (1700), so that a sterilization effect on a large area can be expected while using a small amount of sterilization device, thereby reducing cost and sterilization. Simultaneous improvement in effectiveness can be achieved.

Main and resident sterilization device based system

Figure 10 is a block diagram showing the configuration of a comprehensive restroom sterilization management system including a main sterilization device and an in-room sterilization device. As shown in FIG. 10, the restroom comprehensive sterilization management system (1000b) including the main sterilization device and the occupancy sterilization device according to an embodiment of the present invention further includes the main sterilization device 1800 and the occupancy sterilization device 1900. It can be included.

Figure 11 is an exemplary diagram of the comprehensive bathroom sterilization management system of Figure 10. As shown in FIG. 11, for example, the restroom comprehensive sterilization management system 1000b including the main sterilization device and the occupancy sterilization device according to an embodiment of the present invention includes the first main sterilization device 1800-1 and the second sterilization device 1800-1. It may be provided with at least one main sterilization device 1800, such as the 2 main sterilization device 1800-2, and includes a first occupancy sterilization device 1900-1, a second occupancy sterilization device 1900-2, and a third occupancy sterilization device 1900-2. At least one occupancy sterilization device 1900 may be provided, such as the occupancy sterilization device 1900-3.

According to one aspect, the main sterilization device 1800 may be arranged, for example, in the open space 10 and configured to perform sterilization of the open space. FIG. 12 is a detailed block diagram of the main sterilization device of FIG. 10.

As shown in FIG. 12, the main sterilization device 1800 according to an embodiment of the present invention may include a surface sterilization unit 1010a, an air sterilization unit 1020a, and a detection sensor 1103. That is, the main sterilization device 1800 may be configured to perform air sterilization and surface sterilization.

More specifically, but not exclusively, the main sterilizing device 1800 may be equipped with, for example, an ultraviolet LED to perform sterilization of the surface and may be equipped with a photocatalytic filter (e.g. a ceramic titanium oxide coating) and an ultraviolet LED for the photocatalytic reaction. Equipped with a photocatalyst reaction, air sterilization can be performed. For example, power may be supplied by a 12 V adapter, but is not limited to this.

The main sterilizing device (1800) combines photocatalytic filters and ultraviolet LED sterilizing technology to implement a two-stage air purification system suitable for multi-use facilities that removes ultrafine dust, harmful odors, viruses and bacteria, improving indoor air quality and providing fresh air. It can be configured to supply. For example, the active oxygen generated by the photocatalytic filter decomposes acetaldehyde, which is a carcinogen, as well as ammonia and toluene, which are the causes of various odors, and can be expected to have a deodorizing effect that removes various odors.

In addition, active oxygen generated by the photocatalytic filter can suppress the production of volatile organic compounds such as metals and sulfates, which are the causes of fine dust, into water and carbon dioxide, thereby removing substances harmful to the human body. Therefore, the effect of removing fine dust can be expected. Meanwhile, the effect of eliminating viruses and bacteria can also be expected by preventing proliferation and reproduction by destroying the DNA proteins and nucleic acids of microorganisms using ultraviolet LED.

That is, it is possible to remove indoor odor, remove fine dust, and sterilize indoor air, and may additionally be provided with a temperature measurement sensor and/or a humidity measurement sensor to measure indoor temperature and humidity.

Figure 16 is a perspective view of an exemplary main sterilization device. As exemplarily shown in FIG. 16 , the main sterilizing device 1800 may include an air intake port 1810 that sucks in air for space sterilization and an air outlet 1820 that discharges sterilized air. Additionally, the main sterilization device 1800 is equipped with an ultraviolet lamp 1830 for surface sterilization and can perform surface sterilization. The main sterilizing device 1800 is equipped with a detection sensor 1840 to detect whether a human body is detected around the main sterilizing device 1800. Meanwhile, the operation indicator lamp 1850 can be configured to light in conjunction with the lighting of the ultraviolet lamp 1840. Since ultraviolet rays are non-visible rays and cannot be confirmed by the user as to whether they are operating, an operation indicator lamp 1850 is provided so that visible rays are emitted when the ultraviolet ray lamp is operated, allowing the user to check whether ultraviolet rays are being irradiated. .

For example, ultraviolet LEDs can be used to sterilize bathroom interior surfaces (partitions, floors, toilets, sinks, etc.), and a photocatalyst system can sterilize and deodorize the air inside the bathroom. Based on the human body detection sensor, safety can be guaranteed by sterilizing in the absence of the user. For example, the air sterilizing unit may be configured to operate at all times regardless of the presence or absence of a user. For example, the supply of electricity may be connected to the power source of the indoor light so that it operates in conjunction with the indoor light. Additionally, it can be configured to measure data such as sterilization time, indoor temperature, and indoor humidity, and transmit it to the control unit in real time. Related information may be displayed through the display unit. For example, the display unit can be implemented as a monitor installed at the entrance to the bathroom.

In more detail, but not by way of limitation, the photocatalytic filter is configured to remove fine dust/deodorize/sterilize, and may be implemented with a ceramic titanium dioxide coating having a size of 36 mm x 23 mm x 10 mm. . For example, it can be configured to respond to ultraviolet light of UV 365 nm.

- Brushless motor

- Thermoplastic blade (UL94V-opbt)

- Power: DC 12V / 0.1A

- Noise: 19~25 dB

- Airflow volume: 60~100 CFM

According to one aspect, the occupancy sterilization device 1900 may be configured, for example, to be disposed in at least one occupancy space (20-1, 20-2, 20-3) and perform sterilization of the occupancy space. FIG. 13 is a detailed block diagram of the in-house sterilization device of FIG. 10.

As shown in FIG. 13, the in-room sterilization device 1900 according to an embodiment of the present invention may include a surface sterilization unit 1010b and a detection sensor 1102. That is, the in-room sterilization device 1900 may be configured to perform surface sterilization.

More specifically, but not exclusively, the room sterilization device 1900 can sterilize individual room interior surfaces (partitions, floors, toilets, handles, etc.) with ultraviolet LEDs. For example, the presence of the user can be confirmed by the operation of the human body detection sensor, and the human body detection sensor can ensure safety by sterilizing the device in the user's absence. Meanwhile, the user's presence time can be measured, and if the user does not move for a certain period of time, the user's situation can be transmitted to the control unit in real time to provide a warning or notification of an emergency situation.

Figure 17 is a perspective view of an exemplary in-room sterilization device. As exemplarily shown in FIG. 17 , the in-room sterilization device 1900 may be provided with an ultraviolet lamp 1920 for surface sterilization to perform surface sterilization. The occupancy sterilization device 1900 is equipped with a detection sensor 1910 to detect whether a human body is detected around the occupancy sterilization device 1900. Meanwhile, the operation indicator lamp 1930 may be configured to light in conjunction with the lighting of the ultraviolet lamp 1920. Since ultraviolet rays are non-visible rays and cannot be confirmed by the user as to whether they are operating, an operation indicator lamp 1930 is provided so that visible rays are emitted when the ultraviolet ray lamp is operated, allowing the user to check whether ultraviolet rays are being irradiated. .

Meanwhile, in the present description, the detection sensor 1101, the detection sensor 1102, and the detection sensor 1103 may be referred to as a first detection sensor, a second detection sensor, and a third detection sensor, respectively. According to one aspect of the present invention, the detection sensor unit 1100 may include a first detection sensor 1101, a second detection sensor 1102, and a third detection sensor 1103. For example, the first detection sensor 1101 is connected to the toilet paper dispensers 30-1, 30-2, and 30-3 respectively arranged in at least one occupied space 20-1, 20-2, and 20-3. The second detection sensor 1102 may be integrated into the in-room sterilization device 1900, and the third detection sensor 1103 may be integrated into the main sterilization device 1800. In addition, the detection sensor unit 1100 may include various detection sensors placed in a specific location of the bathroom or part of the system configuration.

According to one embodiment, the detection sensor unit 1100 of the present invention includes a first detection sensor 1101 installed in the dispenser, a second detection sensor 1102 integrated in the in-room sterilization device, and a third sensor integrated in the main sterilization device. It includes a detection sensor 1103, and control of the sterilization device can be performed based on at least one of the first to third detection sensors.

For example, the control unit 1200 may detect the presence of a human body in each occupied space based on at least one of the first detection sensor and the second detection sensor and stop the operation of the corresponding occupancy sterilization device. That is, based on the detection sensor installed in the dispenser or integrated in the occupancy sterilization device 1900, whether a human body is present is sensed for each occupancy room, and the corresponding operation of the occupancy sterilization device 1900 is performed for the occupancy room in which the human body is detected. can be stopped to minimize the impact on the human body.

Meanwhile, the control unit 1200 may be configured to stop the operation of the surface sterilizing unit provided in the main sterilizing device by detecting the presence of a human body in the open space based on the third detection sensor. That is, based on the detection sensor provided in the main sterilizing device 1800, it can be determined whether a human body exists in the space where the main sterilizing device 1800 is placed, and based on this sensing result, at least the main sterilizing device ( 1800), the operation of the surface sterilizing unit (for example, an ultraviolet lamp) can be stopped. For example, even when detecting a human body, the air sterilizing unit of the main sterilizing device 1800 may be configured to continue operating.

surface sterilization department

According to one embodiment of the present invention, the surface sterilizing unit 1010 may be provided in at least one of, for example, a mobile sterilizing device 1700, a main sterilizing device 1800, or an in-house sterilizing device 1900. It is not limited and can be included in the system in various forms and configured to sterilize surfaces.

Specifically, the surface sterilizing unit 1010 may be configured to sterilize surfaces existing in an occupied space or an open space based on ultraviolet rays. For example, sterilization can be performed by radiating ultraviolet rays to the surface of the bathroom (e.g., toilet partition, floor, toilet, sink, etc.) based on an ultraviolet radiation device such as an ultraviolet LED.

Visible light has a boundary between red and purple, and the light in the region with a frequency higher than violet and lower than X-rays is called ultraviolet light. The solar energy reaching the ground also contains less than 5% of ultraviolet rays of 293-400[nm]. Just like applying sunscreen to your skin when playing in the water or going outdoors, light may be perceived as not very beneficial to the general public. Particularly in regions such as Australia, exposure to ultraviolet rays has increased due to the depletion of the ozone layer in polar regions, so it is considered a necessity for outdoor activities and is also known to be linked to skin cancer. On the other hand, in regions such as Gumi, it is also used as a light source for skin tanning, and its application as a sterilizing device and ozone generator in the engineering field is growing.

Additionally, ultraviolet rays are invisible wavelengths within the Solar Spectrum range and contain energy. Ultraviolet rays are almost similar to the wavelength of visible light, but have a shorter wavelength. Ultraviolet rays are measured as 1/1,000,000 mm, the unit is expressed as angstrom (A) or nano meter (NM), and are divided into three areas: UV-A, UV-B, and UV-C.

The sterilizing effect of ultraviolet rays is related to the wavelength of ultraviolet rays, and the wavelength is maximized around 250 to 260 nm. Ultraviolet rays are absorbed by proteins and nucleic acids, which are the main components of all microorganisms. Ultraviolet rays block the activity of microbial DNA (deoxyr ibonucleic acid) or destroy it. Thus, it prevents the proliferation and reproduction of microorganisms. In other words, it can produce a sterilizing effect by destroying bacteria, mold, viruses, etc.

In general, even if a living organism receives ultraviolet radiation and a chemical change occurs in the molecules or cells of the area irradiated by the photon energy of the radiation, causing partial damage or injury, the cells in the area receiving the damage or injury are affected. is restored by metabolism. Therefore, when the entire organism is large, the proportion of parts that receive damage or injury is usually smaller than that of the entire organism, so unless it is continuously irradiated with ultraviolet radiation, situations directly related to the survival of the organism do not occur.

However, in cases where the size of an entity is small, such as microorganisms such as bacteria or mold, the ratio of the damaged or injured part to the entire entity increases, leading to the death of the microorganism. Using this, it becomes possible to kill harmful microorganisms by irradiating them with ultraviolet radiation, which has a large amount of photon energy. This is the sterilizing effect of ultraviolet radiation. The wavelength band of ultraviolet radiation where sterilizing effect increases is 220~310[nm]. Sunlight also contains ultraviolet radiation around 300 [nm], so if you dry your bedding on a very clear day, you can sterilize various germs adhering to the bedding. In this case, humidity affects ultraviolet sterilization, and the lower the humidity, the greater the effect. It is known to have a sterilization efficiency of 100[%] at a relative humidity of 60[℃], a sterilization efficiency of 67[%] at a relative humidity of 70[℃], and a sterilization efficiency of 60[%] at a relative humidity of 80[℃]. Temperature also has an effect; 20 to 25[℃] is optimal, and at 0[℃], the effect is about 60[%] compared to 20[℃].

When looking at transparency, many materials do not transmit ultraviolet radiation, but some types of materials only transmit a limited range of wavelengths. The degree of penetration varies depending on the thickness and properties of the material. In general, transparent water (approximately 10 to 80 [cm] of drinking water: absorbs 90 [%] of sterilizing lines) and air have good permeability. For reference, the transmission limit wavelength range of materials is: water: 185 [nm], ordinary glass: 300 [nm], cellophane: 260 [nm], air: 190 [nm], cornea of the eye: 295.4 [nm], lens: 310. It is [nm].

When examining the effects of ultraviolet radiation by wavelength on the human body, ultraviolet radiation has many applications in the industrial field, but it basically has large energy, so it is necessary to avoid irradiating the human body beyond a certain limit regardless of the irradiated area. Regarding the safety standards for the allowable amount of optical radiation, international standardization (IEC-CIE standardization) has been carried out by IEC and CIE since 1997, and in 2002, the basic general provisions were recognized by a vote of each CIE member country and the CIE standard was established. It was enacted and announced as. Additionally, some countries are establishing their own national standards. Among the national standards of each country, the US ANSI standard is the representative one, and the CIE international standard mentioned above is the basis. Regarding the basic thinking of the safety standards of light sources (ultraviolet radiation) according to this CIE standard, biological or pathological research has been conducted to date on biological injuries to the human body, and the effects of each wavelength band have been studied.

air sterilization department

According to one embodiment of the present invention, the air sterilizing unit 1020 may be provided in at least one of, for example, a mobile sterilizing device 1700, a main sterilizing device 1800, or an in-room sterilizing device 1900. It is not limited and can be included in the system in various forms and configured to sterilize surfaces.

Specifically, the air sterilizing unit 1020 can sterilize and deodorize the air around the photocatalyst by irradiating ultraviolet rays to the photocatalyst that reacts to ultraviolet rays. The photocatalyst may be, for example, titanium dioxide, and a lamp that irradiates ultraviolet rays to such titanium dioxide may be provided. Air sterilization can be performed by the photocatalyst reacting with ultraviolet rays and reacting with oxygen or hydrogen in the air flowing into the air sterilizing unit to generate hydroxide (OH Radical).

A catalyst refers to a role in a chemical reaction that changes or improves the reaction rate of an external substance without changing itself. For example, the photocatalyst uses titanium dioxide, which has increased photoreactivity by irradiation with ultraviolet rays below 280 nm, and has excellent durability and wear resistance. Titanium dioxide itself is a non-toxic, eco-friendly material that does not cause secondary pollution.

Looking at the principle of photocatalytic reaction, electrons generated by irradiation of ultraviolet rays on the surface of the photocatalyst react with O ₂ , H ₂ O or H ₂ in the air, and generate superoxide anions and hydroxyl radical-type active oxygen on the surface of titanium dioxide. You can. In particular, hydroxyl radicals have high oxidation and reduction potentials, so they suppress the generation of fine dust by oxidizing and precipitating volatile organic compounds (VOCS), the source of fine dust, and remove odor by reacting with non-decomposable pollutants such as acetaldehyde. can do. It can also oxidize harmful bacteria, including pathogenic bacteria and viruses. Therefore, a sterilizing action can be performed on the air in the space to be sterilized.

dispenser

As shown in FIG. 11, a toilet paper dispenser (30-1, 30-1, 30-2, 30-3) may be provided. According to one aspect of the present invention, it is possible to add various additional configurations to such a dispenser 30.

FIG. 14 is a block diagram showing an exemplary configuration of the dispenser of FIG. 11, and FIG. 18 is a front view of an exemplary dispenser. 14 and 18, according to one aspect of the present invention, the dispenser 30 includes a detection sensor 1101, an emergency rescue button 31, a remaining amount detection sensor 33, and a display unit 35. At least one or more of may be provided.

As described above, the detection sensor 1101 may be referred to as, for example, the first detection sensor 1101, and may be configured to sense the presence or absence of a human body in the occupied space.

According to one aspect, the toilet paper dispenser 30 may include an emergency rescue button 31 for illegal voyeurism or emergency situations. The control unit 1200 generates an alarm sound through a speaker provided in the restroom in response to the emergency rescue button 31 being activated and transmits a rescue message to the manager device 2000 linked to the restroom comprehensive sterilization management system. It can be configured.

Meanwhile, the remaining amount detection sensor 33 may be configured to sense the remaining amount of toilet paper provided in the toilet paper dispenser. For example, the remaining amount of toilet paper may be detected through any sensor such as a weight sensor or a laser sensor. If it is determined that the remaining amount is below the threshold, information on insufficient remaining amount can be transmitted to the control unit 1200 or the manager device 2000 so that the toilet paper can be replaced.

The display unit 35 can display various information. For example, the display unit may be configured to display advertisements, and may also display policy promotions or guidance information from public institutions. Furthermore, bathroom status information can also be displayed through the display unit.

More specifically, but not exclusively, if the user spots an illegal photographer and presses the emergency button, an alarm sound is transmitted from the speaker built into the dispenser and the situation can be transmitted to the entrance monitor and the manager's smartphone. If the power source is a dispenser that uses an advertising screen, a constant power source is required, so electrical work may be required. Here, the advertisement may be a combination of public service advertisement and commercial advertisement. Meanwhile, a dispenser with only an alarm device and no advertising screen can also be used with a battery. For example, it can be configured to check when to charge with a battery indicator light. Meanwhile, by using a rechargeable battery, it is possible to transmit an emergency situation to the entrance monitor and manager at the same time as sending an emergency alarm sound. The warning sound sent from the dispenser has the effect of stimulating anxiety in illegal photographers and stopping crime. Signals can be sent to monitors and administrators to protect user privacy from crimes.

Display part

According to one embodiment of the present invention, a display unit 1400 may be further provided and configured to display various additional information.

FIG. 15 is an exemplary diagram of the display unit of FIG. 10. As shown in FIG. 15, the display unit 1400 may be configured to display status information of the restroom. For example, the control unit 1200 may generate information about the status of the bathroom based on information acquired through each configuration of the system and display it through the display unit.

As exemplarily shown in FIG. 15 , the bathroom status information displayed through the display unit may include at least one of occupancy status information, temperature information, humidity information, and hygiene status evaluation information.

For example, based on a detection sensor provided in each occupied space, it can be determined whether each occupied space is in use, and the display unit 1400 indicates the occupancy of at least one occupied space, such as vacant or in use, or an emergency situation. Status information may be displayed. The number of occupied spaces and empty seats may be displayed as numbers.

Meanwhile, as additional information, for example, information from various sensors such as a temperature sensor or a humidity sensor provided in the main sterilizing device 1800, the in-room sterilizing device 1900, or the mobile sterilizing device 1700 or included as a separate configuration. It may be displayed on the display unit 1400. For example, bathroom temperature information or bathroom humidity information may be displayed.

Meanwhile, according to one aspect, information about the current sanitary state of the restroom may be displayed by a system or device according to an embodiment of the present invention. For example, in Figure 15, the hygiene status is expressed as a numerical value, such as hygiene 98%.

The evaluation of the sanitary condition can be determined by logic from various factors, such as the ratio of the operating time to the standard time of the sterilizing device or sterilizing unit, the distance from the surface to be sterilized, or the intensity of ultraviolet irradiation.

According to one aspect, the control unit 1200 may be configured to determine hygiene status evaluation information based on the space sterilization index and the surface sterilization index for the restroom. For example, depending on the settings, a space sterilization index indicating the degree of sterilization of the air in the bathroom can be calculated, and a surface sterilization index indicating the degree of sterilization of the surface of the bathroom can be calculated. For example, it may be configured to determine comprehensive hygiene status evaluation information by assigning weight to either the space sterilization index or the surface sterilization index.

For example, the space sterilization index may be determined to be inversely proportional to the volume of the space corresponding to the air sterilization unit and proportional to the ratio of operating time to the reference time period of the air sterilization unit. According to one aspect, it may be determined by reflecting the results of a space sanitary condition experiment measured for the reference volume and the reference time ratio and the measurement volume and measurement time ratio. For example, the relationship between the volume covered by one air sterilization unit and the space hygiene status can be quantified through experimentation. In addition, for example, the relationship between the sanitary condition and the ratio of the time the air sterilizing unit operates within a standard time period, such as 24 hours, can be determined through experiment. This relationship can be quantified or logicalized to determine the ratio of operating time to the current reference time period and the space sterilization index corresponding to the volume covered by one air sterilizing unit. According to one aspect, an artificial neural network that calculates a spatial sterilization index may be provided. For example, by training an artificial neural network based on a plurality of learning data labeled with a sanitary status evaluation value determined based on the measurement results of the volume covered by one air sterilization unit and the ratio of operation time to the reference time period, currently. It is also possible to implement a space sterilization evaluation model that outputs a space sterilization index by inputting the volume covered by one air sterilization unit and the ratio of operating time to the standard time section.

Meanwhile, the surface sterilization index may be determined to be inversely proportional to the evaluation value of the distance from the surface sterilization unit to the surface to be sterilized and proportional to the ratio of the operation time to the reference time section of the surface sterilization unit. For example, the reference distance evaluation value may be, for the mobile sterilizing device 1700, an average value of the distances from each point on the movement path along which the mobile sterilizing device moves to the surface to be sterilized.

According to one aspect, the standard distance evaluation value and the reference time ratio may be determined by reflecting the measured surface hygiene state experiment results and the measurement distance evaluation value and measurement time ratio. For example, the relationship between the reference distance evaluation value and surface hygiene status can be quantified through experimentation. In addition, for example, the relationship between the surface sanitary state and the ratio of the time the surface sterilization unit operates within a standard time period, such as 24 hours, can be determined through experiment. This relationship can be quantified or logicalized to determine the surface sterilization index corresponding to the operating time ratio and reference distance evaluation value for the current reference time section. According to one aspect, an artificial neural network that calculates a surface sterilization index may be provided. For example, evaluating the current measurement distance by training an artificial neural network based on a plurality of learning data labeled with the measurement distance evaluation value and the ratio of operation time to the reference time interval with the hygiene status evaluation value determined based on the measurement results. You can also implement a surface sterilization evaluation model that outputs a surface sterilization index by entering a value and the ratio of operating time to a reference time interval.

Regarding the evaluation of sanitary conditions, the following criteria may be reflected. For example, in relation to the space sterilization index, the sterilization efficiency increases in proportion to the sterilization time per Roubaix (1 cubic meter), the sterilization efficiency increases in proportion to the time (irradiation time) of the sucked air in the sterilizer, and the Roubaix (1 cubic meter) The sterilization efficiency decreases in inverse proportion to the sterilization space per 1 cubic meter, or the sterilization efficiency increases or decreases in inverse proportion to the sterilization time and space per rube (1 cubic meter) and implement this in logic by reflecting at least one of various criteria. After sterilization, the sterilization effect can be calculated by calculating test data for each installation location and reflected in the hygiene index. In addition, with respect to the surface sterilization index, sterilization efficiency increases in proportion to UV-C wavelength type and irradiation time, sterilization efficiency decreases in inverse proportion to UV-C wavelength type and distance, and UV-C wavelength type, sterilization time and distance are inversely proportional. By reflecting at least one of the standards such as increase or decrease in sterilization efficiency, this can be implemented in logic, and the sterilization effect after sterilization can be calculated by calculating test data for each installation location and reflected in the hygiene index.

Meanwhile, as shown in FIG. 15, the information displayed on the display unit 1400 may be configured to be transmitted and displayed on the manager device 2000 of the system according to an embodiment of the present invention. According to one aspect, information displayed on the display unit 1400 may include management record ledger information for a restroom. In general, it is coated on a cosmetic wall, and a management record can be created at a set time period using a marker so that users can check it. According to one aspect of the present invention, the information displayed on the display unit 1400 can include management record ledger information for the restroom. For example, the manager device 2000 may be equipped with a management record ledger input function and the manager may be configured to input ledger information into the management record ledger on the manager device 2000. According to one aspect, the control unit 1200 determines whether the manager device 2000 is located inside the restroom based on any one of various means, such as GPS information of the manager device 2000 or beacon information that can be received only at a short distance. can be determined, and the management record ledger information can be controlled to be inputtable in response to determining that the manager device 2000 is present inside the restroom.

Toilet comprehensive control system

According to one embodiment of the present invention, it is possible to perform management of a plurality of restrooms by one integrated control system.

For example, it may operate based on a BLDC motor to allow air outside the air sterilizing unit 3200 to flow into the air flow path 3240 inside the air sterilizing unit 3200 through the air intake port 3210. However, the blowing fan should be understood as a general term for a configuration for introducing air into the air flow path through any mechanism other than a motor-based fan.

As shown in FIG. 21, according to one embodiment of the present invention, the air flow path 3240 includes a plurality of bends to alleviate the flow of air introduced into the air intake port and reduce the residence time inside the air flow path. It can be configured to increase. In Figure 21, a plurality of refracting parts are provided in a right-angled form to bend the air flow, but the refracting parts are not limited to the right-angled form. For example, the air flow path has a zigzag shape or a three-dimensional refracting shape. The refracted portion may be formed in a bent or curved state of various shapes to increase the residence time of the air inside the air flow path.

Meanwhile, the air flow path 3240 is disposed at predetermined intervals inside the air flow path and protrudes from the inner surface of the air flow path to alleviate the flow of air flowing into the air intake port and increase the residence time inside the air flow path.

In other words, by forming protrusions inside the air flow path, it is possible to block the flow of air introduced through the air inlet and cause disturbance, thereby allowing the introduced air to stay inside the air flow path longer.

According to one aspect, the protrusion 3245 may be configured to reflect ultraviolet rays irradiated from the second ultraviolet lamp 3260. Accordingly, the ultraviolet rays emitted from the second ultraviolet lamp 3260 may be configured to irradiate the air flow path 3240 without a shadowed area to further activate the photocatalyst reaction. According to one aspect, the protrusion 3245 may be formed of a light-transmitting material that transmits ultraviolet rays and may be configured to allow ultraviolet rays from the second ultraviolet ray lamp 3260 to pass through, thereby preventing the generation of a shadow area of ultraviolet rays. According to one aspect, some of the plurality of protrusions may be configured to reflect ultraviolet rays, and some of the plurality of protrusions may be configured to transmit ultraviolet rays. For example, a protrusion within a predetermined threshold distance from the second ultraviolet lamp 3260 may be configured to pass ultraviolet light, and a protrusion outside a predetermined threshold distance from the second ultraviolet lamp 3260 may be configured to reflect ultraviolet light. there is.

Meanwhile, in Figure 21, for example, it is illustrated that a plurality of second ultraviolet lamps 3260 are provided at each end of the refracting portion, but the arrangement structure of the second ultraviolet lamps 3260 of the present invention is not limited thereto. For example, the second ultraviolet lamp 3260 may be implemented as a single lamp, or may be implemented as multiple point light sources, for example, disposed at multiple points on the flow path and configured to minimize the negative area.

Referring again to FIG. 19, the detection sensor 3300 may be configured to detect whether a human body is present at the installation site of the air and surface sterilization device. The detection sensor may be any one of sensors for detecting whether a human body is detected, such as a laser sensor or an acoustic sensor. The control unit 3400 may be configured to control the surface sterilization unit 3100 or the air sterilization unit 3200.

Here, according to one aspect, the control unit 3400 stops the operation of the surface sterilizing unit 3100 in response to the detection sensor 3300 detecting a human body, and the air sterilizing unit 3200 is independent of whether the human body is detected. It can be controlled to operate properly. In other words, the surface sterilizing unit 3100, which affects the human body, stops operation when it detects the presence of a human body, and the air sterilizing unit 3200, which does not emit ultraviolet rays to the human body, is controlled to operate regardless of the presence of a human body. can do.

Here, the control unit 3400 may be configured to stop the movement of the mobile sterilizing device in response to the detection sensor 3300 detecting the human body.

Meanwhile, referring again to FIG. 19, the distance measuring unit 3500 may be configured to measure the distance from the air and surface sterilizing device to the surface to be sterilized. The distance measuring unit may be implemented as any sensor among various sensors for measuring distance, such as a laser or sound wave sensor.

According to one aspect, the control unit 3400 is configured to determine sanitary status evaluation information of a bathroom in which the device is installed based on a space sterilization index and a surface sterilization index, and the space sterilization index is a space corresponding to the air sterilization unit. It is determined to be inversely proportional to the volume and proportional to the operating time ratio for the reference time section of the air sterilizing unit, and is determined by reflecting the results of the space hygiene condition experiment measured for the reference volume and reference time ratio and the measurement volume and measurement time ratio. , the surface sterilization index is inversely proportional to the evaluation value of the distance from the first ultraviolet lamp to the surface to be sterilized and is determined to be proportional to the ratio of operating time to the reference time period of the surface sterilization unit, the reference distance evaluation value and the standard It can be determined by reflecting the surface hygiene condition test results measured for the time ratio, the measurement distance evaluation value, and the measurement time ratio.
