Description

Disinfection and humidification device for improving indoor environment {APPARATUS FOR DISINFECTION AND HUMIDIFICATION FOR IMPROVING THE INDOOR ENVIRONMENT}

The present disclosure relates to a disinfection and humidification device for improving an indoor environment, and more particularly, to a device installed on the ceiling to spray direct water from a tap water in the form of mist and to treat harmful substances in the room.

In recent years, domestic air quality has improved in developing country-type pollution conditions such as sulfur compounds (SOx) and carbon monoxide (CO) thanks to various air pollution reduction policies such as the government's expansion of clean fuel and low-sulfur oil supply and the supply of low-emission vehicles. It is a trend.

However, the level of pollution such as PM10 (fine dust having a diameter of about 10 μm) is gradually increasing or rather worsening, and the form of air pollution is being converted to that of developed countries.

In particular, compared to major cities in Organization for Economic Cooperation and Development countries, the concentration of fine dust in the metropolitan area of Korea is 15 to 35 times higher and is reported to be at the lowest level. According to a report by the Korea Economic Research Institute (KEI) in 2002, it is reported that the cost of damage caused by fine dust is estimated to reach about 10 trillion won. .

On the other hand, fine dust is one of the main air pollutants, and harmful substances such as sulfate, nitrate, and heavy metals are attached to the surface of the particles, and cause serious harm to the human body by depositing in the lungs or bronchi. Such fine dust from the outside may accumulate indoors, and even if ventilation is performed to remove fine dust, it may be difficult to ventilate because there is a possibility that more fine dust from the outside may be introduced. In addition, even in the general case of having an air purifier for filtering fine dust, only a partial area of air can be purified, so there is a limit to having several air purifiers in order to purify the air in a wide range.

In this regard, there is a case of water cleaning to remove fine dust, and it is reported that the effect of water cleaning is quite effective. Therefore, many studies have been conducted on devices for removing fine dust with water, and efforts are being made to effectively dispose the water injection device in the indoor space.

Existing water spraying devices were designed to solve outdoor problems such as heat, dryness, and fine dust. Therefore, it was difficult to use indoors due to the large volume and excessive design of the product.

In addition, conventional humidifiers used indoors have a water container inside to supply water, and a user directly changes the water therein. Accordingly, the space to be placed is inevitably selective, which leads to a limited humidification range. Furthermore, even if it is designed to receive direct water supply, it faces a problem that is difficult to commercialize due to the phenomenon of water forming or leaking due to the pressure.

1 is a block diagram showing the structure of a disinfection and humidification device according to an embodiment of the present disclosure.

Referring to FIG. 1, the disinfection and humidification device 100 according to an embodiment of the present disclosure includes a main frame (not shown), a direct water supply unit 110, a humidifier unit 120, a sterilization unit 130, and a control unit ( 140) may be included.

According to one embodiment, the main frame may be designed to be coupled to the ceiling in a state in which a predetermined storage space in which various components of the device 100 are fixed is formed. The main frame forms the skeleton of the disinfection and humidification device 100, and may be injected with metal or plastic, but is not limited to the exemplified material.

According to one embodiment, the main frame may be formed in a circular plate shape. In addition, the main frame may include a circular first frame having a first radius set with a center as a reference, and a circular second frame having a second radius, the cross section of which is formed in a “T” shape. Here, the first radius may be designed smaller than the second radius. The first frame and the second frame are in close contact with the ceiling, and the first frame may protrude more than the second frame toward the floor. Of course, the main frame may have various shapes, such as a rectangular cross section perpendicular to the longitudinal direction, and is not particularly limited by the present disclosure.

According to one embodiment, a control unit 140 for controlling various operations of the device 100 may be accommodated in one area of the space where the first frame is in close contact with the ceiling, and the direct water supply unit 110 and humidifier may be stored in another area. Some components of unit 120 may be accommodated. In addition, the sterilization treatment unit 130 may be accommodated in the space in which the first frame protrudes toward the floor. However, the space in which each component is accommodated is not limited thereto.

The direct water supply unit 110 according to an embodiment serves to supply direct water to the inside of the device 100 by being directly connected to the waterworks, and referring to FIG. 2, an embodiment of the structure of the direct water supply unit 110 to explain.

Figure 2 is a block diagram for explaining the detailed structure of the direct water supply unit according to an embodiment of the present disclosure.

The direct water supply unit 110 according to an embodiment of the present disclosure may include a first pipe 10, a micro filter 111, a pressure reducing valve 112, and an electromagnetic valve 113.

The first pipe 10 according to one embodiment, one end is accommodated in the main frame and the other end is connected to the water supply, it is possible to supply direct water of the water supply. For example, the first pipe 10 may be a plastic or silicone hose connected to any water supply pipe existing in the indoor space, but the material is not limited thereto.

According to one embodiment, the first pipe 10 may be designed in various forms depending on the components of the direct water supply unit 110 and the space in which they are placed. For example, the first pipe 10 is a part connecting the water supply pipe and the microfilter 111, a part connecting the microfilter 111 and the pressure reducing valve 112, the pressure reducing valve 112 and the solenoid valve 113 ) and a part connecting the electromagnetic valve 113 and the humidifier 120. In addition, the first pipe 10 may be further divided based on the location of the water supply or the internal space of the main frame in which the direct water supply unit 110 is accommodated. Each end of the divided parts may be coupled to each component of the direct water supply unit 110 or coupled to a connecting member of an appropriate shape (eg, a nipple of a date, T, A, Y, etc.). Of course, the shape of the first pipe 10 is not limited thereto, and the configuration in which the first pipe 10 is divided is merely a matter of changing the design of an actual product for facilitating the flow of water or connecting components. Therefore, in the present disclosure, the first pipe 10 is defined as the entire pipe through which direct water from the tap water flows to the humidifier 120, not the pipe of each divided part.

A micro filter 111 according to an embodiment may be connected to water supply through the first pipe 10 . That is, the direct water supplied from the tap water passes through the micro filter 111, and the micro filter 111 serves to remove foreign substances (rust, impurities, etc.) from the direct water.

According to one embodiment, the micro filter 111 may be installed outside the device 100 and may be installed on the ceiling by being coupled to a predetermined fixing means. Alternatively, the micro filter 111 may be disposed on the outer wall of the main frame or inside the main frame in consideration of design factors. In addition, the micro filter 111 may be designed to be easily detachable for regular replacement. In addition, the air gap of the microfilter 111 may be determined based on the water quality of the direct water and the predetermined water quality of the purified water that has passed through the filter 111, and if necessary, a predetermined pre-treatment filter between the microfilter 111 and the water supply. can be placed.

According to one embodiment, the pressure reducing valve 112 may be connected to the micro filter 111 through the first pipe 10. That is, the direct water passing through the micro filter 111 passes through the pressure reducing valve 112, and the pressure reducing valve 112 serves to reduce the internal pressure of the first pipe 10 to a predetermined level.

According to one embodiment, the pressure reducing valve 112 may drop the water pressure of direct water supplied from the water supply to a critical pressure that the first pipe 10 can tolerate and maintain it in that state. For example, when the internal pressure of the first pipe 10 is 4 bar by direct water supply, the amount of direct water passing through the pressure reducing valve 112 is adjusted, starting from the portion connected to the outlet of the pressure reducing valve 112. The internal pressure of the first pipe 10 may be kept constant in a state where the pressure is reduced to 2 bar. Accordingly, it is possible to prevent a phenomenon in which the amount of water entering the humidifying unit 120 exceeds a permissible value due to an excessively fast flow of direct water. Furthermore, it is possible to minimize the risk of damage to parts involved in the flow of water, such as various valves or nipples in the device due to the inflow of a lot of water. In addition, it is possible to prevent water from forming or leaking according to the inflow of a lot of water, thereby eliminating inconvenience that may be given to the user.

According to one embodiment, the pressure reducing valve 112 is designed in the form of an automatic control valve having a preset pressure level to ensure stability. Alternatively, the pressure reducing valve 112 may be designed in the form of a manual valve whose pressure level can be adjusted by a user. In this case, the user can freely change the amount of direct water supplied according to the performance degradation or temporary error that occurs while the device 100 is used. In addition, when the user wants to leave the device 100 for a long period of time due to absence or the like, the user can close the pressure reducing valve 112 to block the flow of direct water at the source, thereby minimizing the deterioration in the lifespan of the device 100.

According to one embodiment, the electronic valve 113 may be connected to the pressure reducing valve 112 through the first pipe 10 . That is, the flow of direct water passing through the pressure reducing valve 112 is blocked by the electromagnetic valve 113 or passes through the electromagnetic valve 113 when a predetermined condition is satisfied.

According to one embodiment, the electronic valve 113 may be a normally open solenoid valve. First, since the apparatus 100 is always open in the standby mode, direct water passing through the pressure reducing valve 112 may be transferred to the humidifying unit 120 . On the other hand, when the direct water is sprayed in the form of mist by the humidifier 120, the electronic valve 113 is closed by the command of the controller 140, and the supply of the direct water to the second pipe 20 is blocked. That is, the electromagnetic valve 113 cuts off the water supply when the humidifier 120 starts spraying and supplies water again when the operation of the humidifier 120 is completed. Direct water does not affect the operation of the humidifier 120 to keep the internal pressure constant.

Referring back to FIG. 1 , the humidifying unit 120 according to an embodiment performs a humidifying function of spraying the direct water supplied from the first pipe 10 in the form of mist. In addition, while performing the humidifying function, the internal pressure of the humidifying unit 120 may be maintained at atmospheric pressure. Hereinafter, an embodiment of the structure of the humidifier 120 will be described with reference to FIG. 3 .

3 is a block diagram for explaining a detailed structure of a humidifier according to an embodiment of the present disclosure.

The humidifier 120 according to an embodiment of the present disclosure includes a second pipe 20, a first storage unit 121, a spray unit 122, a second storage unit 123, and a supply pump 124. can include

Referring to FIG. 3 , the second pipe 20 according to an embodiment may be designed so that all or part of the direct water supplied to the humidifier 120 circulates through the humidifier 120 . Specifically, water flowing through the first pipe 10 is transferred to the second pipe 20 and flows through the second pipe 20 . Water flowing through the second pipe 20 may first be stored in the first storage unit 121 . Thereafter, the water stored in the first storage unit 121 is transported to the spraying unit 122 and all or part of it is sprayed indoors, and the remaining water after spraying passes through the second storage unit 123 to the first storage unit ( 121) and stored. As such, a circulation structure in which one end of the second pipe 20 is coupled to one coupling member of the first storage unit 121 and the other end of the second pipe 20 is coupled to another coupling member of the first storage unit 121. can be designed as Here, when there are a plurality of spraying units 122 , pipes connecting each spraying unit may also be included in the second pipe 20 .

According to one embodiment, the second pipe 20 may be designed in various forms according to the components of the humidifier 120 and the space in which it is placed. For example, the second pipe 20 connects the solenoid valve 113 of the direct water supply unit 110 and the first storage unit 121, and connects the first storage unit 121 and the injection unit 122. A part connecting each injection part 122, a part connecting the injection part 122 and the second storage part 123, a part connecting the second storage part 123 and the supply pump 124, It may be divided into parts connecting the supply pump 124 and the first storage unit 121 . As will be described later, when the humidifier 120 further includes components such as the electromagnetic valve 125, the resistance unit 126, and the check valve 127, a portion connecting them may be added. In addition, the second pipe 20 may be further divided based on the inner space of the main frame in which the humidifier 120 is accommodated. Each end of the divided parts may be coupled to each component of the humidifier 120 or coupled to a connection member having an appropriate shape (for example, a nipple having a date, a T shape, a Y shape, etc.). Of course, the shape of the second pipe 20 is not limited thereto, and the configuration in which the second pipe 20 is divided is merely a matter of changing the design of an actual product for facilitating water flow or connecting components. Therefore, in the present disclosure, the pipe of the entire route through which water flows in the humidifier 120 is defined as the second pipe 20, not the pipe of each divided part.

The first storage unit 121 according to an embodiment may be connected to the direct water supply unit 110 through the second pipe 20. Alternatively, it may be connected to the direct water supply unit 110 through the first pipe 10 according to the design. In addition, the first storage unit 121 may be connected to the injection unit 122 and the supply pump 124 through the second pipe 20 . That is, the first storage unit 121 may include a plurality of coupling members coupled to each end of the second pipe 20 leading to the direct water supply unit 110, the injection unit 122, and the supply pump 124. .

According to one embodiment, the first storage unit 121 may include a predetermined space capable of storing water, and may store the direct water supplied by the direct water supply unit 110 . That is, direct water passing through the solenoid valve 113 when the device 100 is in standby mode is transferred to the first storage unit 121 and stored therein. In addition, according to the internal pressure of the first storage unit 121 due to the stored direct water, the first storage unit 121 may supply the stored direct water to the second pipe 20 leading to the injection unit 122. As such, the first storage unit 121 may serve as a kind of water tank for storing direct water to be sprayed indoors in the form of mist.

According to one embodiment, the first storage unit 121 may perform a purification action of stored direct water. For example, the first storage unit 121 may include a predetermined photocatalytic filter. The photocatalytic filter may be disposed in one area of the storage space of the first storage unit 121 . As a result, various kinds of foreign substances in the direct water that may occur while reaching the first storage unit 121 are removed, so that cleaner humidification can be achieved.

According to one embodiment, the first storage unit 121 may include a first quantity detection sensor for detecting whether the straight water is filled to a preset first reference height. Here, the first reference height may refer to a storage amount of direct water to which the injection unit 122 smoothly sprays a predetermined amount of water, but does not apply excessive pressure. At this time, the first quantity detection sensor is installed at a position corresponding to the first reference height can detect whether or not the direct water supplied reaches the reference height. When the signal of the first quantity detection sensor is received, the control unit 140 transmits a command to close the electronic valve 113 of the direct water supply unit 110 to block direct water supply from being further supplied.

According to one embodiment, the first storage unit 121 may include a second quantity detection sensor for detecting that direct water is not supplied. At this time, the second quantity detection sensor is installed at a position corresponding to the second standard height of the first storage unit 121 can detect whether or not the direct water stored therein falls to the second standard height. Here, the second reference height may mean a storage amount of direct water at which the injection unit 122 cannot operate. When the signal of the second quantity detection sensor is received, the control unit 140 determines that the electronic valve 113 of the direct water supply unit 110 is closed by error, and commands the electronic valve 113 to be opened.

According to one embodiment, the injection unit 122 may be connected to the first storage unit 121 through the second pipe 20 . That is, the injection unit 122 may receive the direct water stored in the first storage unit 121 and perform a humidifying function of spraying water in the form of mist into the room. At this time, the jetting unit 122 having reached direct water may inject a predetermined amount of water.

As such, the spraying unit 122 sprays water particles like fine mist so that the fine dust is combined with water and falls to the ground, thereby reducing the concentration of fine dust in the air. For example, the device 100 of the present disclosure can exhibit the effect of an air curtain by being disposed at a door or a window.

In addition, the apparatus 100 of the present disclosure has an effect of lowering the ambient temperature by vaporizing the sprayed water. In addition, the apparatus 100 of the present disclosure may add liquids of other chemicals in addition to water, and thus, various functions such as disinfection (disinfection), pesticide spraying, and water supply function can be exhibited.

According to one embodiment, the humidifying unit 120 may include at least one spraying unit 122 . For example, when the number of spraying units 122 is n, each spraying unit 122 may be connected to each other through the second pipe 20 . Specifically, when the jetting unit 122 to which the direct water of the first storage unit 121 arrives first is referred to as the first jetting unit, the second pipe 20 is the first jetting unit - the second jetting unit, and the second jetting unit. It may include a part divided into each pipe connecting the fourth injection part to the third injection part, to the n−1th injection part to the nth injection part.

According to one embodiment, when there are a plurality of spraying units 122, each spraying unit may sequentially perform a spraying operation based on the order in which direct water arrives. For example, when the number of spraying units 122 is n and the spraying unit 122 to which direct water arrives first is referred to as a first spraying unit, direct water may be sequentially sprayed from the first spraying unit to the nth spraying unit. . Alternatively, the injection unit 122 may be grouped into groups of a preset number, and each group may sequentially perform an injection operation based on the order in which direct water arrives. For example, when the number of injection units 122 is n and the three injection units are designed to form one group, the controller 140 controls the first to third injection units when direct water reaches the third injection unit. At the same time, the humidifier 120 may be controlled to perform a spraying operation. Of course, when the direct water reaches the n-th injection unit, the n-2-th to n-th injection units simultaneously perform the injection operation. Alternatively, all of the plurality of spraying units 122 may simultaneously perform the spraying operation. For example, when the number of jetting units 122 is n and the jetting unit 122 to which the direct water arrives first is referred to as a first jetting unit, the control unit 140 determines that when the direct water reaches the nth jetting unit, the first jetting unit The humidifier 120 may be controlled so that the spraying unit to the nth spraying unit simultaneously perform spraying operations.

According to one embodiment, the injection unit 122 may be fixed to the outermost area of the main frame. For example, when the main frame has a circular plate shape and is composed of a first frame and a second frame having different radii, the injection unit 122 may be installed in a space between the first frame and the second frame. . In addition, when there are a plurality of spraying units 122, each spraying unit 122 may be spaced apart from each other by a predetermined distance and fixed to the main frame. For example, when the main frame has a circular plate shape, each spraying unit 122 may be installed in a state of being spaced apart by a predetermined arc length along the circumference of the circle.

According to one embodiment, the injection unit 122 may be implemented as a nozzle having a predetermined shape. For example, when there are a plurality of injection units 122, they are preferably designed in a “T” shape. That is, each injection unit 122 is provided with a connecting member on both sides coupled to the second pipe 20, but a nozzle portion for spraying direct water into the room may be installed on the main frame in a state facing the floor. The nozzle can supply direct water to the room in the form of steam.

The second storage unit 123 according to an embodiment may be connected to the injection unit 122 through the second pipe 20 . That is, the second storage unit 123 is injected by the injection unit 122 and the remaining direct water is delivered, and the second storage unit 123 includes a predetermined storage space to temporarily store the remaining direct water after being injected. Do it. In addition, the second storage unit 123 may be connected to the supply pump 124 through the second pipe 20 . When the supply pump 124 is operated according to the command of the control unit 140, the water stored in the second storage unit 123 flows to the second pipe 20 connected to the supply pump 124, which is It is transferred to section 121. That is, the second storage unit 123 is coupled to the coupling member coupled to the second pipe 20 of the portion leading to the injection unit 122 and the second pipe 20 of the portion leading to the supply pump 124 Other coupling members may be included.

According to one embodiment, the second storage unit 123 may perform a purification action of stored direct water. For example, the second storage unit 123 may include a predetermined photocatalytic filter. The photocatalytic filter may be disposed in one area of the storage space of the second storage unit 123 . As a result, various paper materials in the direct water that may occur while reaching the second storage unit 123 can be removed, and the direct water delivered to the first storage unit 121 can be stored again in a clean state.

According to one embodiment, both the first storage unit 121 and the second storage unit 123 may be designed to perform a purifying action. In this case, the first purifying action is performed in the first storage unit 121 and the second purifying action is performed in the second storage unit 123 . Therefore, the direct water can be maintained in a clean state in which impurities or foreign substances are removed while circulating the humidifier 120 .

According to one embodiment, the second storage unit 123 may perform a predetermined operation for maintaining the internal pressure of the second pipe 20 constant after injection. Preferably, an operation of maintaining the internal pressure of the second pipe 20 at atmospheric pressure may be performed according to a command of the control unit 140 . As a result, a difference in air pressure between the device 100 and the outside does not occur, thereby preventing water from leaking or condensing and falling to the floor, and specific embodiments thereof will be described later.

The supply pump 124 according to an embodiment may be connected to the second storage unit 123 through the second pipe 20 . Alternatively, depending on the design, the supply pump 124 may be included in the second storage unit 123 or directly connected to it. The supply pump 124 serves to transfer part or all of the water stored in the second storage unit 123 to the first storage unit 121 according to a command of the control unit 140 . That is, the supply pump 124 is coupled to the second storage unit 123 or coupled to the second pipe 20 leading to the second storage unit 123 and a coupling member connected to the first storage unit 121. Another coupling member coupled to the pipe 20 may be included.

According to one embodiment, the supply pump 124 may be operated for a predetermined time after the injection operation of the injection unit 122 is finished. For example, when a plurality of spraying units 122 are configured, the water in the second storage unit 123 is removed by being operated for k seconds during or after the operating time of the spraying unit 122 that last sprayed water. It can be transferred to one storage unit 121. Meanwhile, when the supply pump 124 is operated, the control unit 140 may open the electronic valve 113 of the direct water supply unit 110 to supply fresh direct water to the first storage unit 121 .

As such, when the device 100 is in standby mode, the direct water is stored in the first storage unit 121, and when the device 100 is operated, the direct water stored in the first storage unit 121 reaches the spraying unit 122. This causes a certain amount of water to be sprayed into the room. In addition, when the operation of the device 100 is blocked, the injection of the injection unit 122 is terminated, and accordingly, the water remaining in the injection unit 122 or the second pipe 20 is collected in the second storage unit 123, , which are collected in the first pipe 10 again by the operation of the supply pump 124. Therefore, even when only some of the plurality of spraying parts 122 perform the spraying operation according to the operation blocking of the device 100, the remaining water is circulated and stored again in the first storage unit 121, so the remaining water is separately discharged. There is no need to do it, and it can prevent damage caused by remaining water, weakening performance, and leaking or dripping.

Referring back to FIG. 3 , the humidifier 120 according to an embodiment of the present disclosure may further include an electromagnetic valve 125 . The electromagnetic valve 125 is a component involved in the movement of the direct water stored in the first storage unit 121, and may be disposed between the first storage unit 121 and the injection unit 122, and is controlled by the control unit 140. is operated by Of course, when there are a plurality of spraying units 122, they may be disposed between the spraying unit 122 and the first storage unit 121, where direct water is first reached.

According to one embodiment, the electromagnetic valve 125 may be a normally closed solenoid valve. Specifically, the electronic valve 125 is basically maintained in a closed state when the injection unit 122 does not operate because the device 100 is in a standby mode. Thus, in the standby mode, direct water supplied from the first storage unit 121 is blocked from flowing to the spraying unit 122 . On the other hand, when the device 100 is operated and the injection unit 122 needs to perform an injection operation, the control unit 140 transmits an open command to the electromagnetic valve 125, and accordingly, the electromagnetic valve 125 It is opened and the direct water stored in the first storage unit 121 is transferred to the spraying unit 122 . In this way, direct water naturally flows due to the water pressure of the first storage unit 121, and by having the solenoid valve 125, the humidifying function of the device 100 can be suppressed in the standby mode.

On the other hand, the disinfection and humidification device 100 according to an embodiment of the present disclosure can keep the pressure inside the pipe constant, preferably by maintaining it at atmospheric pressure, so that water is condensed and falls to the floor due to the air pressure difference with the outside. phenomenon can be prevented.

In this regard, the humidifying unit 120 according to an embodiment of the present disclosure may include at least one resistance unit 126 . For example, the resistance unit 126 may be a kind of wastewater resistor (quantity valve) having a coupling member for coupling both sides of the pipe, and the capacity of the wastewater resistor may be determined according to the pressure reduction level.

According to one embodiment, the resistance unit 126 may be disposed between the first storage unit 121 and the injection unit 122 . For example, as shown in FIG. 3 , the first resistance unit is disposed between the first storage unit 121 and the solenoid valve 125, and the second resistance unit is disposed between the solenoid valve 125 and the injection unit 122. It can be. In this case, the effect of dropping the water pressure to a desired level may be excellent because the precision is supplemented.

Direct water passing through the resistance unit 126 may drop to a preset water pressure level. Accordingly, the internal pressure of the second pipe 20 connecting the first storage part 121 and the injection part 122 can be adjusted to a certain level, and the certain level is preferably atmospheric pressure. For example, when the direct water supply unit 110 is supplied to the humidifying unit 120 in a state where the direct water of the tap water falls from 4 bar to 2 bar by the pressure reducing valve 112 in the direct water supply unit 110, the water pressure of the direct water passing through the resistance unit 126 is It can drop further to 1 bar. As a result, the internal pressure of the second pipe 20 can be maintained at atmospheric pressure, and water formation or leakage caused by water pressure can be prevented while the injection unit 122 operates.

As another embodiment related to pressure, referring to FIG. 3, the second storage unit 123 includes a first gas valve 128 and a second storage unit for introducing external air into the second storage unit 123 ( 123) may include a second gas valve 129 for discharging internal air.

According to one embodiment, the first gas valve 128 has one end fixed to a hose or main frame exposed to the outside and coupled with a suction part for sucking in air, and the other end coupled with the main body of the second storage part 123. It can be. The first gas valve 128 may include a check valve for transferring air from the outside toward the main body of the second storage unit 123 but preventing a reverse flow. The second gas valve 129 may have one end coupled to the main body of the second storage unit 123 and the other end connected to a hose exposed to the outside. The second gas valve 129 may include a check valve for transferring air from the second storage unit 123 to the outside while preventing a reverse flow.

According to one embodiment, the control unit 140 operates the supply pump 124 at a predetermined time based on the operation of the last injection unit 122, and at this time, transmits an open command to the first gas valve 128 can Thus, when the first gas valve 128 is opened, external air flows into the second storage unit 123. That is, when the internal pressure of the second pipe 20 becomes lower than the atmospheric pressure after the injection operation, the flow of water is induced by introducing external air. Accordingly, the pressure of the second storage unit 123 increases, so that the direct water stored in the second storage unit 123 flows into the second pipe 20 leading to the first storage unit 121 .

According to one embodiment, the amount of air introduced into the first gas valve 128 may be set in advance by the control unit 140 . For example, when all injection units 122 have completed their operations, the control unit 140 controls opening and closing of the first gas valve 128 until the internal pressure of the second pipe 20 reaches atmospheric pressure. can do.

According to one embodiment, the controller 140 may transmit an open command to the second gas valve 129 when recognizing that the internal pressure of the second pipe 20 is higher than the atmospheric pressure. Thus, when the second gas valve 129 is opened, the air including the vapor present in the second storage unit 123 is discharged to the outside. That is, when the pressure inside the pipe exceeds the atmospheric pressure due to the operation of the supply pump 124 or other operations, the control unit 140 recognizes this and discharges steam from the second storage unit 123, thereby reducing the pressure inside the pipe. The pressure is always maintained at atmospheric pressure.

According to one embodiment, the amount of air discharged to the second gas valve 129 may be preset in the control unit 140 . For example, the control unit 140 controls the opening and closing of the second gas valve 129 until the internal pressure of the second pipe 20 drops to atmospheric pressure, in line with the case where all injection units 122 have completed their operations. can

According to one embodiment, a predetermined pressure sensing member may be installed in the second storage unit 123 . The control unit 140 can always check whether the pressure inside the second pipe 20 is atmospheric pressure by means of the pressure sensing member, and accordingly, the opening and closing operations of the first gas valve 128 and the second gas valve 129 or open hours can be determined. For example, when a relatively large amount of water is stored in the second storage unit 123 because the operation of the apparatus 100 is stopped while all of the spraying units 122 are not completely sprayed, the control unit 140 controls the pressure Based on the measurement signal of the sensing member, the first gas valve 128 may not be opened or may be opened for a shorter period of time.

In the above, the case where at least one of the first gas valve 128 and the second gas valve 129 is actively controlled by the controller 140 has been described. However, it is not limited thereto, and at least one of the first gas valve 128 and the second gas valve 129 may not be controlled by the control unit 140 . At least one of the first gas valve 128 and the second gas valve 129 may be automatically opened or closed by a pressure difference between atmospheric pressure and the second storage unit 123 . For example, when the pressure inside the second storage unit 123 is lower than atmospheric pressure, the first gas valve 128 is automatically opened to match the atmospheric pressure with the pressure inside the second storage unit 123. That is, the first gas valve 128 may increase the pressure inside the second storage unit 123 to equalize atmospheric pressure. In addition, when the internal pressure of the second storage unit 123 is higher than the atmospheric pressure, the second gas valve 129 is automatically opened to match the atmospheric pressure with the pressure of the second storage unit 123 . That is, the second gas valve 129 lowers the pressure inside the second storage unit 123 to make it equal to atmospheric pressure.

In the conventional device, when the pressure of the injection part is maintained higher than atmospheric pressure even when the operation of the device is stopped, water leaks out of the nozzle included in the injection part due to the difference in pressure, and the leaked water forms on the nozzle, There were cases where condensed water dripped into the room. When the condensed water falls indoors, it sometimes gives people discomfort or discomfort. However, by matching the internal pressure of the second storage unit 123 with the atmospheric pressure, the pressure of the injection unit 122 may be maintained equal to or lower than the atmospheric pressure. Because when the nozzle included in the injection part 122 injects water vapor while the electromagnetic valve 125 is closed, the pressure inside the injection part 122 will drop due to the outflow of the fluid, and by the check valve 127 This is because fluid cannot be supplied from the second storage unit 123 to the injection unit 122 . In addition, since the pressure of the injection unit 122 is lower than or equal to the atmospheric pressure, it is possible to prevent water droplets from forming on nozzles included in the injection unit 122 and falling into the room.

On the other hand, as described above, the second pipe 20 is formed in a circulation structure that allows water to flow in one predetermined direction. ) is placed on the main frame, and problems such as water pressure may cause reverse flow of direct water. In this regard, referring to FIG. 3 , the humidifier 120 according to an embodiment of the present disclosure may include at least one check valve 127 .

According to one embodiment, a check valve 127 may be disposed between the injection unit 122 and the second storage unit 123 . Accordingly, it is possible to prevent a phenomenon in which direct water remaining after being sprayed from the injection unit 122 flows backward due to a water pressure problem. In addition, another check valve 127 may be disposed between the supply pump 124 and the first storage unit 121. Accordingly, in the process of maintaining the pressure inside the pipe at atmospheric pressure or other problems, A reverse flow of direct water transferred from the second storage unit 123 to the first storage unit 121 can be prevented. On the other hand, the number and position of the check valves 127 are only one example, and if the configuration prevents the back flow of the second pipe 20, the design change of the number and position is interpreted as being included in the present invention. It should be.

When the operation of the sterilization unit 130 is commanded by the control unit 140, the suction unit 131 performs a suction operation. Accordingly, indoor air is continuously introduced into the lower end of the device 100 .

According to one embodiment, the suction unit 131 may be designed in the form of a suction fan having a predetermined motor, and the available voltage may be 5-12V, but is not limited thereto. In addition, when the suction unit 131 includes a fan net, it may be designed and arranged in a structure that makes it easy for a user to clean it.

The primary filter 132 according to an embodiment serves to treat harmful particles in the air introduced by the suction unit 131 . For example, the primary filter 132 may be designed as one of an EPA filter, a HEPA filter, and a ULPA filter in which a fiber material is composed of multiple layers to filter fine particles in the air. On the other hand, as shown, the primary filter 132 may be installed at the bottom of the sterilization unit 130, but its location is not particularly limited. In addition, the primary filter 132 may be designed and arranged in a structure that facilitates cleaning or regular replacement for filtering out coarse particles.

The secondary filter 133 according to an embodiment is disposed above the primary filter 132 and serves to supplement the purifying action of the primary filter. For example, the secondary filter 133 may be designed as a photocatalyst filter coated with a predetermined photocatalyst. Here, the photocatalyst may be titanium dioxide (TiO2), but is not limited thereto, and various materials such as ZnO, CdS, ZrO2, and V2O3 may be employed. When the secondary filter 133 is irradiated with light of a predetermined type and wavelength, a catalytic reaction occurs, whereby effects such as decomposition of organic substances in the air passing through the primary filter 132, sterilization, and antibacterial effects are manifested. At this time, the light of the light source unit 135 may be used, or a light irradiation member separate from the light source unit 135 may be included in the secondary filter 133 .

The discharge unit 134 according to an embodiment serves to discharge air that has passed through the secondary filter 133 to the outside. The configuration of the discharge unit 134 is not particularly limited, but is preferably disposed above the suction unit 131 in terms of structure. For example, as shown in FIG. 4 , at least one discharge unit 134 may be configured and disposed near the top of the device 100 .

As such, the sterilization unit 130 according to an embodiment of the present disclosure removes various kinds of harmful bacteria such as fine dust by inhaling indoor air, and performs sterilization and antibacterial treatment, thereby promoting a cleaning effect of indoor air. . In addition, since the device 100 of the present disclosure is coupled to the ceiling, the air cleaning range can be maximized and space efficiency can be improved.

According to an embodiment, the light source unit 135 irradiates light of a predetermined wavelength to sterilize harmful substances on the indoor surface. Although the placement position is not particularly limited, it may be disposed above the secondary filter 133 if it is manufactured in consideration of the interaction with the secondary filter 133 .

According to an embodiment, the control unit 140 may operate the light source unit 135 after a predetermined time elapses after the operation of the suction unit 131 . Alternatively, the light source unit 135 may be operated in parallel with the operation of the suction unit 131 .

For example, the light irradiated by the light source unit 135 may be LED lighting of 380-450 nm UVA, preferably 405 nm. In addition, since the properties of light continuously change, even if it is slightly out of the ultraviolet range, it can have a sterilizing effect. Accordingly, the light source unit 135 emits light with a wavelength slightly out of the ultraviolet range.

can The light source unit 135 can sterilize the indoor space by irradiating ultraviolet rays at a time preset in the controller 140 . The preset time may be determined by the user as a time during which the user does not use the indoor space.

According to an embodiment, the light source unit 135 may include at least one light source of red, green, or blue so that users can visually recognize that ultraviolet rays are being irradiated. At least one of red, green, and blue light sources included in the light source unit 135 may be turned on or off based on a command of the controller 140 . Alternatively, the light source unit 135 may include only a white light source. The white light source included in the light source unit 135 may be turned on or off based on a command of the controller 140 .

According to an embodiment, since the light source unit 135 can be used as an indoor light, a user may not need to install a separate light in the room where the device 100 is installed. Therefore, it is possible to save space for installing lighting indoors. In addition, the utility of the device 100 as an interior accessory may be increased.

Referring back to FIG. 1 , the controller 140 according to an embodiment of the present disclosure may include a processor and a memory.

The entry/exit signal may indicate that a person is entering or may indicate that a person is leaving. The controller 140 may determine whether or not to spray water based on the entry/exit signal. For example, the control unit 140 may control the spraying unit 122 to perform a spraying operation when an entry/exit signal from a human sensor indicates that a person enters. The device 100 may stop dispensing liquid when the exit signal from the human body sensor indicates that a person is leaving.

The controller 140 may periodically receive a signal indicating that the human body has not been detected from the human body sensor. The controller 140 may turn on the light source unit 135 when a signal indicating that the human body has not been detected is obtained from the human body sensor for a first predetermined time. The controller 140 may turn on the light source unit 135 at the first brightness for a second predetermined time. Also, the controller 140 may turn on the light source unit 135 at the second brightness after a predetermined second time. The second brightness may be greater than the first brightness. When the light source unit 135 is turned on and the controller 140 receives a signal indicating that a human body has been detected from the human body sensor, the controller 140 can turn off the light source unit 135 immediately. By operating the device 100 in this way, the situation in which the user is exposed to ultraviolet rays can be minimized.

According to one embodiment, the control unit 140 controls various components of the direct water supply unit 110, the humidifier unit 120, and the sterilization unit 130, thereby providing an indoor humidification method and an indoor air cleaning and hazardous material treatment method. can be done Hereinafter, an embodiment of these methods will be described with reference to FIGS. 5 and 6, and redundant information will be replaced with the aforementioned information.

5 is an operation flowchart of an indoor humidification method performed by a disinfection and humidification device according to an embodiment of the present disclosure.

In step S501, direct water is supplied through the first pipe 10 connected to the tap water, and the direct water can be purified by removing impurities and foreign substances through the micro filter 111.

In step S502, the direct water passing through the micro filter 111 is reduced to a predetermined level of water pressure through the pressure reducing valve 112, and accordingly, the internal pressure of the first pipe 10 may be maintained in a reduced state. there is. For example, when direct water from tap water is supplied at 4 bar, after passing through the pressure reducing valve 112, the internal pressure of the first pipe 10 may be reduced to 2 bar and maintained.

In step S503, the direct water passing through the pressure reducing valve 112 flows to the solenoid valve 113, and in the case of the standby mode of the device 100, the direct water turns the solenoid valve 113 without a special command from the control unit 140. It passes through and is stored in the first storage unit 121 .

In step S504, the direct water stored in the first storage unit 121 flows through the second pipe 20 by the hydraulic pressure of the first storage unit 121. However, the device 100 is in a standby mode, and the flow of direct water in the second pipe 20 is blocked by the normally closed electromagnetic valve 125. Thereafter, when an operation mode of the humidifier 120 is set based on a user's request for humidification, setting information, or a human body sensor, the control unit 140 transmits an open command to the electromagnetic valve 125 . According to the command, the electronic valve 125 is opened and the direct water is transferred to the injection unit 122 through the second pipe 20. At this time, the direct water may pass through at least one resistance unit 126, and accordingly, the internal pressure of the second pipe 20 through which the direct water flows may be reduced to atmospheric pressure and maintained.

In step S505, when the direct water reaches the spraying unit 122, the spraying unit 122 sprays the direct water in the form of mist into the room. When there are a plurality of spraying units 122 , the spraying operation may be performed individually or by group according to the order in which direct water is reached based on a control signal from the control unit 140 . Alternatively, all spraying units 122 may simultaneously spray water according to a control signal from the control unit 140 . At this time, the control unit 140 transmits a closing command to the electromagnetic valve 113 of the direct water supply unit 110 to block the direct water supply to the first storage unit 121 during the injection operation.

In step S506, the remaining direct water after injection is transferred to the second storage unit 123. At this time, the phenomenon that the remaining direct water flows in the reverse direction by passing through the check valve 127 can be prevented.

In step S507 , the control unit 140 may command the operation of the supply pump 124 for a preset time based on the last injection operation among the plurality of injection units 122 . Accordingly, the supply pump 124 performs an operation of flowing the water stored in the second storage unit 123 to the second pipe 20 . At this time, the control unit 140 may open the first gas valve 128 to allow external air to flow into the second pipe 20, and as the air flows in, the pressure of the second pipe 20 may increase to atmospheric pressure. will reach As a result, the direct water stored in the second storage unit 123 can be smoothly transferred to the first storage unit 121 . In addition, when the internal pressure of the second pipe 20 becomes higher than the atmospheric pressure, the control unit 140 opens the second gas valve 129 to discharge the air existing in the second storage unit 123 to the outside, Accordingly, the internal pressure of the second pipe 20 may be constantly maintained at atmospheric pressure.
