As shown in fig. 1, the bathroom environment adjusting apparatus 100 includes a sterilizing liquid dispensing apparatus 1. The bathroom environment adjusting apparatus 100 includes a panel 101, a movable air vane 102, and a mist nozzle 203. The mist nozzle 203 will be described later with reference to fig. 2. In the present embodiment, the bathroom environment adjusting device 100 is a bathroom heater dryer with mist sauna.

The panel 101 is exposed from the ceiling surface of the bathroom. Panel 101 has intake port 103 and discharge port 104 (first opening). Outlet 104 is formed in a horizontally rectangular shape. The panel 101 also has a blow-out opening 105 (second opening). The device 1 for spreading the sterilizing liquid is disposed at a position corresponding to the air outlet 105 of the panel 101. The sterilizing liquid scattering device 1 is a mist generating device for generating mist of the sterilizing liquid. The configuration of the sterilizing liquid scattering device 1 will be described later.

Movable air vane 102 is provided at outlet 104 (first opening). Movable air vane 102 has a shape corresponding to air outlet 104. Movable air vane 102 is openable and closable with respect to outlet 104. In the present embodiment, the movable wind direction plate 102 is rotatable, and the blowing direction of the air blown out from the blowing port 104 can be changed by rotating the movable wind direction plate 102. The movable louver 102 closes (covers) the air outlet 104 when the bathroom environment adjusting device 100 stops the heating operation, the drying operation, and the fog sauna operation, and opens the air outlet 104 when the bathroom environment adjusting device 100 executes the heating operation, the drying operation, or the fog sauna operation. The movable wind direction plate 102 closes (covers) the air outlet 104 when the sterilizing liquid scattering device 1 performs the sterilizing operation. Fig. 1 shows a state in which movable air vane 102 closes air outlet 104.

Next, a configuration of the bathroom environment adjusting device 100 (a bathroom heating and drying device with mist sauna) will be described with reference to fig. 2. Fig. 2 is a diagram showing the configuration of the bathroom environment adjusting apparatus 100 according to embodiment 1.

As shown in fig. 2, the bathroom environment adjusting apparatus 100 includes a body unit 200 and a heat source unit 300. The body unit 200 is provided in the ceiling portion of the bathroom. The heat source unit 300 is provided outdoors. The panel 101 described with reference to fig. 1 is attached to the main unit 200 as an exterior member of the main unit 200.

The heat source unit 300 heats a heating medium for heating and hot water supply water. The heat source unit 300 includes a circulation pump for circulating a heating medium for heating. The heat medium for heating is, for example, hot water or antifreeze. The heat source unit 300 is connected to a supply passage 301, and heats the hot water supplied from the supply passage 301.

The main unit 200 includes a hot water circulation passage 201, a mist water passage 202, a mist nozzle 203, a heating heat exchanger 204, a mist heat exchanger 205, a driving device 206, an air blowing device 210, a control device 220, and the sterilizing liquid dispersing device 1.

The hot water circulation flow path 201 circulates a heating medium for heating between the main unit 200 and the heat source unit 300. Specifically, the circulation pump included in the heat source unit 300 is operated, whereby the heat medium flowing out of the heat source unit 300 flows through the hot water circulation flow path 201. Specifically, the heat medium passes through the heating heat exchanger 204 and the mist heat exchanger 205 in this order, and returns to the heat source unit 300.

The mist water passage 202 is a water passage branched from the supply passage 301, and allows mist water to pass therethrough. The mist water passage 202 is disposed to reach the mist nozzle 203 through the mist heat exchanger 205. The mist nozzle 203 atomizes the water supplied from the mist water passage 202 to spray the water into the bathroom.

In the present embodiment, the supply pipe 13 of the sterilizing fluid dispenser 1 is a water passage branched from the supply passage 301, and water flows from the supply passage 301 into the supply pipe 13 of the sterilizing fluid dispenser 1 by opening the control valve 15. When water is caused to flow from the supply passage 301 into the supply pipe 13 of the sterilizing fluid dispenser 1, the mist water passage 202 closes the electromagnetic valve provided in the mist water passage 202 so as not to allow water to pass therethrough.

The heating heat exchanger 204 faces the movable louver 102 and the sterilizing liquid scattering device 1. The heating heat exchanger 204 converts the air taken in from the intake port 103 described with reference to fig. 1 into warm air. The mist heat exchanger 205 converts water flowing through the mist passage water passage 202 into hot water.

The driving device 206 rotates the movable wind vane 102 within a predetermined rotation angle range. The drive device 206 is, for example, an electric motor. By rotating the movable air vane 102 by the driving device 206, the posture of the movable air vane 102 changes from the posture of closing the air outlet 104 described with reference to fig. 1 to the posture of opening the air outlet 104. The blowing direction of the warm air supplied to the bathroom is changed according to the rotation angle of the movable wind vane 102.

The air blower 210 is a wind generator that generates wind. The blower 210 includes a rotary fan 211 and a fan motor 212. The fan motor 212 rotates the rotary fan 211. The rotary fan 211 is, for example, a sirocco fan (siroccofan).

The rotary fan 211 rotates to suck air from the suction port 103 described with reference to fig. 1. When movable air vane 102 opens air outlet 104 described with reference to fig. 1, the air sucked in from air inlet 103 is blown out from air outlet 104 through heating heat exchanger 204 by the rotation of rotary fan 211. On the other hand, when movable louver 102 closes air outlet 104 described with reference to fig. 1, the air sucked in from air inlet 103 flows toward air outlet 105 (second opening) described with reference to fig. 1 through heating heat exchanger 204 by the rotation of rotating fan 211. In other words, the air flows toward the sterilizing liquid scattering device 1.

The controller 220 controls the operation of the bathroom environment adjusting apparatus 100. Specifically, the heating operation, the drying operation, and the mist sauna operation of the bathroom environment adjusting device 100 are controlled. Further, the controller 220 controls the sterilization operation of the sterilizing liquid dispenser 1.

The control device 220 includes a processor and a semiconductor memory. The processor is, for example, a CPU (Central Processing Unit) or an MPU (micro Processing Unit). The control device 220 includes, for example, a ram (random access memory) and a rom (read Only memory) as a semiconductor memory. The processor executes various processes in accordance with a control program (computer program) stored in the semiconductor memory.

Next, referring to fig. 3, the main unit 200 will be further described. Fig. 3 is an enlarged view of a part of the main body unit 200. As shown in fig. 3, the body unit 200 further includes a holder 230.

The frame body 230 rotatably supports the movable wind vane 102. Specifically, the movable wind vane 102 includes two rotary shafts 102a, and the frame body 230 rotatably supports the two rotary shafts 102 a. One of the two rotary shafts 102a is connected to an output shaft of the drive device 206. The rack 230 supports the sterilizing liquid dispenser 1. Specifically, the main body 121 of the first unit 10 included in the sterilizing fluid dispenser 1 is supported.

Next, the bacteria-removing liquid scattering device 1 according to embodiment 1 will be described with reference to fig. 3. As shown in fig. 3, the cover 121a of the main body 121 includes an opening 125. In the present embodiment, the air blowing device 210 of the bathroom environment adjusting apparatus 100 described with reference to fig. 2 is used to blow the mist of the sterilizing liquid.

Next, referring to fig. 4, the main unit 200 will be further described. Fig. 4 is a diagram showing an air path of the bathroom environment adjusting apparatus 100. As shown in fig. 4, the body unit 200 further includes a fixed wind direction plate 207. The fixed wind direction plate 207 aligns the direction of the wind flowing out of the heating heat exchanger 204 to a predetermined direction (downward direction in the present embodiment).

The frame body 230 supports the main body 121 of the first unit 10 of the device 1 so that a part (lower part) of the first unit 10 protrudes from the air outlet 105 (second opening). As a result, the second unit 20 included in the sterilizing fluid-spreading device 1 is supported so as to be located below the panel 101.

Next, the sterilization operation according to the present embodiment will be described with reference to fig. 4. When the degerming operation is performed, the movable wind direction plate 102 is in a closed state as shown in fig. 4. As a result, the air flowing out of the fixed wind direction plate 207 flows into the opening 125 included in the first unit 10 (the cover 121a of the main body 121) of the bacteria-removing liquid scattering device 1. Therefore, air flowing from the opening 125 toward the liquid surface of the sterilizing liquid is generated, and the mist of the sterilizing liquid is guided to the ceiling surface by the guide surface 251 of the sterilizing liquid scattering device 1.

The structure of the sterilizing liquid scattering device 1 will be described in detail below. Fig. 5 is a plan view of the sterilizing liquid scattering device 1 according to embodiment 1. As shown in fig. 5, the sterilizing liquid scattering device 1 includes an outlet 1 a. The sterilizing liquid dispenser 1 discharges mist of the sterilizing liquid from the discharge port 1a and dispenses the sterilizing liquid in the bathroom.

As shown in fig. 5, the sterilizing liquid scattering device 1 includes a first unit 10 and a second unit 20. In the present embodiment, the outlet 1a is a gap formed between the first unit 10 and the second unit 20.

The first unit 10 includes a support body 12, a supply pipe 13, a water plug 14, and an adjustment valve 15.

The support body 12 supports the second unit 20. In the present embodiment, support body 12 includes a main body 121 and a plurality of support members 122.

In the present embodiment, the main body 121 includes a lid 121 a. Preferably, the cover 121a includes an opening 125 at a central portion. By forming the opening 125 in the center of the lid 121a, the mist of the sterilizing liquid can be radially sent out from the sterilizing liquid dispenser 1 with the sterilizing liquid dispenser 1 as the center. In other words, the mist of the sterilizing liquid can be prevented from being sent out in a specific direction. Therefore, the mist of the sterilization liquid can be sent out without being deflected in a specific direction, and sterilization can be performed in a wider range.

The plurality of support members 122 protrude outward from the main body 121 to support the second unit 20, in the present embodiment, the main body 121 has a rectangular shape in plan view, and the support members 122 protrude from the center of each side of the main body 121, and the supply port 1a is formed around the main body 121. in detail, the supply port 1a is formed between the plurality of support members 122. in the present embodiment, the supply port 1a has a shape of L in plan view, and the bacteria-removing liquid scattering device 1 includes 4 supply ports 1 a. the mist of the bacteria-removing liquid can be supplied from substantially the entire periphery of the main body 121 through the 4 supply ports 1 a.

The supply pipe 13 supplies water to the second unit 20. The supply pipe 13 supplies, for example, tap water. The water plug 14 is provided in the supply pipe 13. The water stopper 14 is openable and closable. When the water plug 14 is in the open state, the supply pipe 13 can supply water. When the water stopper 14 is in the closed state, the supply of water through the supply pipe 13 is blocked. In the present embodiment, the water plug 14 is disposed on the lid 121 a. The regulating valve 15 is provided in the supply pipe 13. The adjustment valve 15 will be described later with reference to fig. 6.

Next, the sterilizing liquid scattering device 1 will be described with reference to fig. 6. Fig. 6 is a sectional view of the sterilizing liquid scattering device 1 according to embodiment 1. In detail, fig. 6 shows a cross section along the line VI-VI of fig. 5.

As shown in fig. 6, main body 121 of support body 12 has a box shape with an open bottom surface, and includes wall portion 121b in addition to cover body 121 a. The wall 121b protrudes downward from an end of the cover 121 a. The support member 122 is connected to the lower end portion of the wall portion 121 b. The supply pipe 13 extends from the cover 121a of the support body 12 to the inside of the second unit 20.

Next, the second unit 20 will be described with reference to fig. 6. The second unit 20 includes a storage portion 21, an electrode pair 22, an ultrasonic wave generating element 23, a water level sensor 24, and a guide member 25. The delivery port 1a described with reference to fig. 5 is formed between the upper end of the guide member 25 and the main body 121 (wall portion 121b) of the support body 12.

The storage section 21 stores a solvent, which is water L in the present embodiment, and the storage section 21 has a box shape with an open top surface, and the supply pipe 13 extends inside the storage section 21 in the present embodiment.

The electrode pair 22 is immersed in the solvent (water L). in the present embodiment, the electrode pair 22 is disposed on the bottom surface of the housing part 21. the sterilization component is generated in the solvent (water L) by applying a voltage to the electrode pair 22. as a result, a sterilization solution in which the solvent (water L) and the sterilization component are mixed is generated in the housing part 21. in other words, the housing part 21 houses the sterilization solution.

In the present embodiment, the sterilization component is silver ions, specifically, each electrode constituting the electrode pair 22 is a metal plate containing a silver monomer, or each electrode is a metal plate containing a titanium metal plate and silver supported on a part or the whole of the surface of the titanium metal, for example, when the plate size of each electrode constituting the electrode pair 22 is set to 5mm × 30mm (thickness 0.3mm), the inter-electrode distance is set to 3mm, and 100m L of tap water having a pH of 7.6 and a hardness of 45 mg/L is stored in the storage part 21, a current of 150mA to 170mA flows between the electrodes and silver ions are eluted from the anode when a voltage of DC5V is applied to the electrode pair 22.

The ultrasonic generator 23 applies ultrasonic vibration to the sterilizing liquid to generate mist of the sterilizing liquid. Specifically, the ultrasonic wave generating element 23 is disposed on the bottom surface of the accommodating portion 21. In other words, the ultrasonic wave generating element 23 is immersed in the sterilizing liquid. The ultrasonic wave generating element 23 irradiates ultrasonic waves from the liquid toward the liquid surface. As a result, a water-jet liquid column is generated on the liquid surface by the sound pressure, and mist (mist of the sterilizing liquid) is generated from the liquid column.

When the sterilizing liquid dispenser 1 dispenses the sterilizing liquid, the water level (height of the liquid surface) of the sterilizing liquid contained in the containing section 21 fluctuates. In the case of generating the mist by the ultrasonic waves, it is necessary to adjust the position (water level) of the liquid surface so that the ultrasonic wave is located on the liquid surface.

The water level sensor 24 detects the position of the liquid level of the sterilization liquid. The control valve 15 is openable and closable. When the control valve 15 is in the open state, water is supplied through the supply pipe 13. When the control valve 15 is in the closed state, the supply of water through the supply pipe 13 is blocked. The regulating valve 15 is opened and closed based on the detection result of the water level sensor 24, and controls the supply of water through the supply pipe 13 so that the ultrasonic wave is positioned at the liquid level. The adjustment valve 15 is, for example, a solenoid valve. The water level sensor 24 is, for example, a float switch. When the water level sensor 24 is a float switch, the water level sensor 24 detects whether the ultrasonic wave is located on the liquid level. Specifically, the water level sensor 24 detects whether the water level of the sterilization liquid is a predetermined water level. The predetermined water level is set in accordance with the wavelength of the ultrasonic wave.

The guide member 25 includes a guide surface 251. Specifically, the inner side surface of the guide member 25 forms a guide surface 251. The guide surface 251 guides the mist of the sterilizing solution to a predetermined surface among the surfaces defining the bathroom so that the mist of the sterilizing solution blown by the blowing device 210 (fig. 2) flows along the predetermined surface. Specifically, in the present embodiment, the air generated from the air blower 210 (fig. 2) is directed toward the liquid surface of the sterilization liquid. The mist of the sterilization liquid is blown toward the guide surface 251 by the air directed toward the liquid surface of the sterilization liquid. As a result, the mist of the sterilizing fluid blown by the blower 210 (fig. 2) is guided to the predetermined surface by the guide surface 251.

In the present embodiment, the guide surface 251 guides the mist of the sterilizing fluid to the ceiling surface of the bathroom. Specifically, the guide member 25 protrudes obliquely upward from the upper end of the side wall of the accommodating portion 21 toward the outside. Therefore, the guide surface 251 is an inclined surface and is inclined so as to be closer to the panel 101 as it is separated from the housing portion 21. As a result, the mist of the sterilizing liquid is sent obliquely upward from the guide surface 251, reaches the ceiling surface of the bathroom via the panel 101, and then flows along the ceiling surface of the bathroom. In other words, the mist of the sterilization liquid is sent obliquely upward from the sending-out port 1 a. Alternatively, the mist of the sterilization liquid is sent out from the guide surface 251 (sending-out port 1a) in the horizontal direction to the upper direction. Further, the mist of the sterilization liquid may be sent out in the horizontal direction from the guide surface 251 (the sending-out port 1 a). For example, if the gap between the upper end of the guide surface 251 and the panel 101 is narrow, the mist of the sterilizing liquid may be sent out in the horizontal direction.

Next, the flow of mist of the sterilizing liquid will be described with reference to fig. 7. Fig. 7 is a view showing the flow of mist of the bactericidal solution according to embodiment 1 of the present invention. Arrows D1 to D3 indicate the direction in which the mist of the sterilization liquid flows.

As shown in fig. 7, the mist of the sterilizing liquid sent from the sterilizing liquid dispenser 1 flows along the panel 101 and then flows along the ceiling SS of the bathroom. The mist of the sterilizing fluid guided along the ceiling SS to the wall surface WS of the bathroom flows downward along the wall surface WS.

The bathroom environment adjustment device 100 according to the present embodiment is explained above with reference to fig. 1 to 7. According to the present embodiment, since the mist of the sterilizing liquid flows along the panel 101 and the ceiling surface SS (example of a predetermined surface) of the bathroom, it is possible to sterilize a wider range of the ceiling surface SS together with the panel 101. Further, according to the present embodiment, the mist of the sterilizing liquid can be radially sent out from the sterilizing liquid dispenser 1 with the sterilizing liquid dispenser 1 as the center. By this, can carry out degerming to the wider scope of ceiling SS.

Further, according to the present embodiment, the mist of the sterilizing fluid guided to the wall surface WS of the bathroom along the ceiling surface SS flows downward along the wall surface WS. Therefore, the sterilizing liquid can be spread on the wall surface WS of the bathroom.

Further, according to the present embodiment, the mist of the sterilizing liquid is sent toward the panel 101 and flows along the ceiling surface SS and the wall surface WS. Therefore, the mist of the sterilizing liquid can be prevented from being inhaled by a person who enters the bathroom during the spraying of the sterilizing liquid. Further, adhesion of the sterilization liquid to a person who enters the bathroom can be suppressed.

Next, the sterilizing liquid scattering device 1 according to the present embodiment will be described with reference to fig. 8(a), 8(b), 9, and 10. Fig. 8(a) is a plan view of the second unit 20 according to embodiment 1. Fig. 8(b) is a bottom view of the second unit 20 of embodiment 1.

As shown in fig. 8(a) and 8(b), the second unit 20 includes a plurality of support holes 20 a. In the present embodiment, the guide member 25 includes a plurality of support holes 20 a. The support hole 20a is a through hole penetrating the guide member 25. The plurality of support holes 20a are formed at positions corresponding to the plurality of support members 122 described with reference to fig. 5.

In the present embodiment, the guide surface 251 has a ring shape. The guide surface 251 is annular, and thereby the mist of the sterilization liquid can be radially sent out from the sterilization liquid dispenser 1 with the sterilization liquid dispenser 1 as the center. In other words, the mist of the sterilizing liquid can be prevented from being sent out in a specific direction. Therefore, the mist of the sterilization liquid can be sent out without being deflected in a specific direction, and sterilization can be performed in a wider range.

Fig. 9 is a sectional view of the sterilizing liquid scattering device 1 according to embodiment 1. In detail, fig. 9 shows a cross section along line IX-IX of fig. 5. As shown in fig. 9, the support members 122 of the first unit 10 are inserted into the corresponding support holes 20a (fig. 8 a and 8 b). The support member 122 is inserted into the support hole 20a, whereby the guide member 25 is supported by the support member 122. In other words, the second unit 20 is supported by the support member 122.

In the present embodiment, the support member 122 detachably supports the guide member 25. In other words, the support member 122 detachably supports the second unit 20. Specifically, at least one of the guide member 25 and the support member 122 is formed of a material having elasticity. For example, at least one of the guide member 25 and the support member 122 may be formed of acrylic resin. At least one of the guide member 25 and the support member 122 has elasticity, so that the support member 122 can be inserted into and removed from the support hole 20a, and as a result, the second unit 20 can be attached and detached.

Fig. 10 is a diagram showing a state in which the second unit 20 is separated from the first unit 10. In the present embodiment, the support member 122 detachably supports the second unit 20 (guide member 25). Therefore, as shown in fig. 10, the second unit 20 can be easily separated from the first unit 10. In other words, the second unit 20 can be easily removed from the bathroom environment adjustment device 100.

As described with reference to fig. 1 and 2, air blower 210 (fig. 2) sucks air from the bathroom through suction port 103 (fig. 1) of panel 101, and as a result, dust and dirt from the outside are easily taken into the liquid (water L or bacteria-removing liquid) stored in storage unit 21 by the air blown from air blower 210 (fig. 2). furthermore, when water L is tap water, there is a possibility that scale of tap water accumulates in storage unit 21. therefore, in view of sanitary conditions, it is necessary to periodically clean the inside of second unit 20. according to the present embodiment, second unit 20 can be separated from first unit 10, and therefore, the inside of second unit 20 can be easily cleaned.

Further, when silver ions are used as the sterilization component of the sterilization liquid, the silver ions are reduced and aggregated to form a colloid, and thereby the periphery of the ultrasonic wave generating element 23 is centered to cause blackening due to the silver colloid. Since the silver colloid may cause a malfunction of the ultrasonic wave generating element 23, the inside of the housing portion 21 needs to be periodically cleaned to remove the silver colloid. According to the present embodiment, since the second unit 20 can be separated from the first unit 10, the inside of the housing portion 21 can be easily cleaned.

In the present embodiment, silver ions are eluted from the anode of the electrode pair 22. Therefore, the anode (electrode) becomes small in accordance with the period of use of the sterilizing fluid dispenser 1. Therefore, it is necessary to periodically replace the electrode pair 22. In the present embodiment, the electrode pair 22 is provided in the housing portion 21. The second unit 20 can be separated from the first unit 10. Therefore, the electrode pair 22 can be easily replaced.

In addition, the guide member 25 and the support member 122 are preferably formed of a material having elasticity. The guide member 25 and the support member 122 each have elasticity, whereby the second unit 20 can be more easily separated from the first unit 10. When the second unit 20 is removed from the first unit 10, the water plug 14 is preferably closed so that water does not drip from the supply pipe 13.

Next, referring to fig. 11, the bathroom environment adjustment device 100 will be further described. Fig. 11 is a block diagram of a bathroom environment adjustment device 100 according to embodiment 1. As shown in fig. 11, the bathroom environment adjustment device 100 further includes an operation unit 30 and first to fourth power supply devices 41 to 44.

The operation unit 30 receives an operation by a user. The operation unit 30 transmits a signal corresponding to the operation of the user to the control device 220. The operation unit 30 is installed on a wall surface of a bathroom or a wall surface of a dressing room adjacent to the bathroom, for example.

In the present embodiment, the operation unit 30 includes a warm air button 31, a bathroom dry button 32, a fogger sauna button 33, a sterilization button 34, a stop button 35, and a display 36. The operation unit 30 includes a processor, a semiconductor memory, and an interface circuit. The processor is, for example, a CPU or MPU. The operation section 30 includes, for example, a RAM and a ROM as semiconductor memories. The processor executes various processes in accordance with a control program (computer program) stored in the semiconductor memory. The interface circuit performs communication between the operation unit 30 and the control device 220. The control device 220 also includes an interface circuit that performs communication between the control device 220 and the operation unit 30.

The warm air button 31 is a button for instructing the start of a warm air operation (warm air operation). That is, when the user presses the warm air button 31, the operation unit 30 transmits a signal instructing the start of the warm air operation to the control device 220. When the control device 220 receives a signal indicating the start of the heating operation, the bathroom environment adjusting device 100 executes the heating operation (heating operation).

The bath dry button 32 is a button for instructing the start of a drying operation (drying operation). That is, when the user presses the bathroom drying button 32, the operation unit 30 transmits a signal instructing the start of the drying operation to the control device 220. When the control device 220 receives a signal indicating the start of the drying operation, the bathroom environment adjustment device 100 executes the drying operation (drying operation).

The mist warmth button 33 is a button for instructing the start of a mist warmth operation (mist warmth operation). That is, when the user presses the mist warmth button 33, the operation unit 30 transmits a signal instructing the start of the mist warmth operation to the control device 220. When the control device 220 receives a signal indicating the start of the mist sauna operation, the bathroom environment adjusting device 100 executes the mist sauna operation (mist sauna operation).

The sterilization button 34 is a button for instructing the start of the sterilization operation. That is, when the user presses the sterilization button 34, the operation unit 30 transmits a signal instructing the start of the sterilization operation to the control device 220. When the control device 220 receives a signal instructing the start of the sterilization operation, the sterilization liquid distribution device 1 performs the sterilization operation for a predetermined period.

The stop button 35 is a button for instructing stop of various operation operations. For example, when the user presses the stop button 35 during the heating operation, the operation unit 30 transmits a signal instructing the stop of the heating operation (heating operation) to the control device 220. When the control device 220 receives a signal instructing the stop of the heating operation, the bathroom environment adjusting device 100 stops the heating operation (heating operation). When the user presses the stop button 35 during the sterilization operation, the operation unit 30 transmits a signal instructing the stop of the sterilization operation to the control device 220. When the control device 220 receives a signal instructing the stop of the sterilization operation, the sterilizing fluid dispenser 1 stops the sterilization operation even before a predetermined period of time has elapsed after the start of the sterilization operation.

The display 36 is controlled by the processor to display various information. For example, the display 36 displays a message indicating the running action being performed. For example, the display 36 displays the time elapsed after the start of the sterilization operation or the remaining time until the end of the sterilization operation.

In the present embodiment, upon receiving a signal instructing the start of the sterilization operation from the operation unit 30, the control device 220 controls the operations of the first power supply device 41 to the fourth power supply device 44 so that the sterilization operation is executed.

The first power supply device 41 is controlled by the control device 220 to generate a voltage for energizing the electrode pair 22. Specifically, the control device 220 controls the first power supply device 41 so that the electrode pair 22 is energized until the silver ion concentration reaches a predetermined concentration.

The second power supply unit 42 is controlled by the control unit 220 to generate a voltage for driving the ultrasonic wave generating element 23. As a result, ultrasonic waves are generated from the ultrasonic wave generating element 23.

The third power supply device 43 is controlled by the control device 220 to generate a voltage for driving the fan motor 212. As a result, the rotary fan 211 described with reference to fig. 2 rotates to generate wind. Further, it is preferable that the controller 220 periodically changes the rotation speed of the fan motor 212 and periodically changes the amount of air blown by the blower 210 (fig. 2) during the sterilization operation. By changing the amount of air blown by the air blower 210 (fig. 2), the distance of scattering of the mist of the sterilizing liquid can be changed, and the sterilizing liquid can be more uniformly attached to the panel 101, the ceiling surface SS, and the wall surface WS.

The fourth power supply device 44 is controlled by the control device 220 to generate a voltage for driving the control valve 15. More specifically, the controller 220 controls the fourth power supply 44 based on the output of the water level sensor 24 so that the water level of the sterilization liquid becomes a predetermined water level. Specifically, when the water level of the sterilization liquid is lowered by the sterilization operation, the controller 220 opens the control valve 15. As a result, as described with reference to fig. 6, water is supplied from the supply pipe 13 to the storage section 21. When the water level of the sterilization liquid rises to a predetermined water level, the controller 220 closes the control valve 15.

Next, the flow of processing executed by the control device 220 will be described with reference to fig. 11 and 12. Fig. 12 is a flowchart showing a process executed by control device 220 according to embodiment 1. More specifically, fig. 12 shows a flow of processing executed by the control unit 220 during the bacteria removing operation. When receiving a signal instructing the start of the sterilization operation from the operation unit 30, the control device 220 starts the processing shown in fig. 12.

As shown in fig. 12, when the control device 220 receives a signal instructing the start of the sterilization operation, the electrode pair 22 is first energized so that the concentration of silver ions becomes a predetermined concentration (step S1).

After the electrode pair 22 is energized, the controller 220 generates an ultrasonic wave from the ultrasonic wave generator 23 (step S2). The controller 220 drives the fan motor 212 to generate air for blowing the mist of the sterilization liquid (step S2). As a result, the mist of the sterilization liquid is sent out from the sending-out port 1a described with reference to fig. 5 and 6.

When the mist of the sterilization liquid starts to be sent out, the controller 220 determines whether or not the water level of the sterilization liquid is a predetermined water level based on the output of the water level sensor 24 (step S3).

When determining that the water level of the sterilizing liquid is the predetermined water level (yes at step S3), the controller 220 determines whether or not a predetermined period has elapsed since the signal instructing the start of the sterilizing operation is received (step S4).

On the other hand, if the controller 220 determines that the water level of the sterilization liquid is not the predetermined water level (no in step S3), the control valve 15 is driven so that the water level of the sterilization liquid becomes the predetermined water level (step S5). In other words, as described with reference to fig. 6, the controller 220 supplies water from the supply pipe 13 to the storage part 21, and raises the water level of the sterilizing liquid to a predetermined water level.

When the water level of the sterilization liquid rises to a predetermined water level, the controller 220 closes the control valve 15 and then energizes the electrode pair 22 so that the concentration of silver ions becomes a predetermined concentration (step S6). After the electrode pair 22 is energized, the controller 220 determines whether or not a predetermined period has elapsed since the signal instructing the start of the sterilizing operation is received (step S4).

If control device 220 determines that the predetermined period has not elapsed (no at step S4), the process returns to the process at step S3. On the other hand, if control device 220 determines that the predetermined period has elapsed (yes at step S4), it ends the processing shown in fig. 12.

The flow of processing executed by the control device 220 is described above with reference to fig. 11 and 12. According to the processing shown in fig. 12, the concentration of silver ions in the sterilizing solution can be maintained at a predetermined concentration, and the sterilizing solution can be sprayed into a bathroom.

Next, with reference to fig. 11 and 13, the flow of other processing executed by the control device 220 will be described. Fig. 13 is a flowchart showing another example of the processing executed by the control device 220 according to embodiment 1. In detail, fig. 13 shows another example of the processing executed by the control unit 220 during the bacteria removing operation. When receiving a signal instructing the start of the sterilization operation from the operation unit 30, the control device 220 starts the processing shown in fig. 13. The following description deals with points different from the processing shown in fig. 12.

As shown in fig. 13, when the controller 220 determines that the water level of the sterilizing liquid is the predetermined water level (yes in step S3), it determines whether or not a first predetermined period has elapsed since the signal instructing the start of the sterilizing operation is received (step S11).

When the control valve 15 is driven to return the water level of the sterilizing liquid to the predetermined water level (step S5), the controller 220 determines whether or not a second predetermined period has elapsed since the signal instructing the start of the sterilizing operation is received (step S12). The second predetermined period is shorter than the first predetermined period.

If the controller 220 determines that the second predetermined period has not elapsed (no in step S12), it energizes the electrode pair 22 so that the concentration of silver ions becomes the predetermined concentration (step S6). On the other hand, if the controller 220 determines that the second predetermined period has elapsed (yes in step S12), it does not energize the electrode pair 22. Therefore, when the second predetermined period of time elapses, the concentration of silver ions decreases every time water is supplied from the supply pipe 13 to the housing portion 21.

In the present embodiment, the second predetermined period is set so that the liquid contained in the storage section 21 returns from the sterilizing liquid to the ordinary water L before the first predetermined period elapses, and therefore, before the first predetermined period elapses, the ultrasonic wave generating element 23 applies ultrasonic vibration to the water L to generate mist of water, and the air blowing device 210 (fig. 2) blows air to the mist of the water L.

The flow of other processing executed by the control device 220 is described above with reference to fig. 11 and 13. According to the treatment shown in fig. 13, after the sterilizing solution is attached to the faceplate 101, the ceiling surface SS, and the wall surface WS, water is attached to the faceplate 101, the ceiling surface SS, and the wall surface WS, and the sterilizing effect by the silver ions can be maintained for a long time. Specifically, when the sterilization liquid is dried, silver colloid is precipitated. The silver colloid has small sterilization effect on mould and common bacteria. Therefore, in order to maintain the sterilization effect by the silver ions adhering to the faceplate 101, the ceiling surface SS, and the wall surface WS for a long time, it is necessary to prevent the sterilization liquid from drying. In contrast, according to the treatment shown in fig. 13, the drying of the sterilization liquid adhering to the faceplate 101, the ceiling surface SS, and the wall surface WS can be prevented. Therefore, the antibacterial effect by the silver ions adhering to the faceplate 101, the ceiling surface SS, and the wall surface WS can be maintained for a long time.

Further, when the sterilizing solution is dried and the silver colloid is precipitated, blackening occurs in the faceplate 101, the ceiling surface SS and the wall surface WS due to the silver colloid, and the appearance is deteriorated. In contrast, according to the treatment shown in fig. 13, the drying of the sterilization liquid adhering to the faceplate 101, the ceiling surface SS, and the wall surface WS can be prevented. Therefore, the occurrence of blackening can be suppressed.

In the treatment shown in fig. 13, the ordinary water is sprayed after the sterilization liquid is sprayed, but the ordinary water may be sprayed after a predetermined period of time has elapsed from the completion of the spraying of the sterilization liquid. In this case, even if the sterilization liquid is dried and the silver colloid is precipitated, the silver colloid can be dissolved to generate silver ions. Also, even if blackening occurs, the silver colloid can be dissolved, whereby blackening is less likely to be conspicuous.

Next, referring to fig. 14(a) and 14(b), the energization time of the electrode pair 22 will be described. Fig. 14(a) is a graph showing the time change of the silver ion concentration. FIG. 14(b) is a graph showing the sterilization effect of silver ions.

In FIG. 14(a), the vertical axis represents the silver ion concentration, and the horizontal axis represents the elapsed time, more specifically, FIG. 14(a) represents the silver ion concentration measured by storing 100m L of tap water having a pH of 7.6 and a hardness of 45 mg/L in the storage part 21 and applying a voltage of DC5V to the electrode pair 22. further, the plate size of each electrode constituting the electrode pair 22 is set to 5mm × 30mm (thickness: 0.3 mm). further, the inter-electrode distance is set to 3 mm. As shown in FIG. 14(a), the silver ion concentration reaches 500ppb at the elapsed time of 3 minutes, and the silver ion concentration becomes 1000ppb or more at the elapsed time of 5 minutes.

In FIG. 14(b), the vertical axis shows the bacteria removal rate, and the horizontal axis shows the silver ion concentration, in FIG. 14(b), the curve marked with × shows the bacteria removal rate of Staphylococcus aureus, and the curve marked with black circles shows the bacteria removal rate of Blakeslea fungus, as shown in FIG. 14(b), general bacteria (for example, Staphylococcus aureus) can remove 90% or more by the silver ion concentration of 50ppb to 100ppb, and Blakeslea fungus (Cladosporium, Mycosporium) can remove 90% or more by the silver ion concentration of 400ppb to 500 ppb.

Therefore, by energizing the electrode pair 22 for about 3 minutes, it is possible to elute silver ions that can sterilize general bacteria and mold.

The description above is directed to embodiment 1. According to embodiment 1, the sterilizing fluid can be uniformly attached to the ceiling surface SS and the wall surface WS of the bathroom without being deviated to a specific range. Further, the sterilizing liquid can be uniformly adhered to the panel 101 of the bathroom environment adjusting apparatus 100.

In the present embodiment, the guide surface 251 is an inclined surface, but the guide surface 251 may include a horizontal surface. For example, the guide surface 251 may include a horizontal surface parallel to the panel 101 or the ceiling surface SS. In this case, the mist of the sterilizing liquid is sent out from the guide surface 251 in the horizontal direction, and flows along the panel 101 and the ceiling surface SS.

In the present embodiment, the bacteria-removing liquid scattering device 1 includes 4 delivery ports 1a shaped like L, but the number and shape of the delivery ports 1a are not particularly limited, and fig. 15(a) is a diagram showing a modification of the bacteria-removing liquid scattering device 1 according to embodiment 1.

As shown in fig. 15(a), the sterilizing liquid scattering device 1 may include a plurality of circular outlets 1 a. Specifically, in the apparatus 1 for spreading a disinfectant solution shown in fig. 15(a), a plurality of circular outlet ports 1a are arranged along the circumferential direction around the main body 121 of the support body 12. The support body 12 includes a flange portion 124 that supports the guide member 25 (second unit 20) instead of the plurality of support members 122 described with reference to fig. 5 and 6. A plurality of circular discharge ports 1a are formed in the flange portion 124. In addition, in the device 1 for spreading a sterilization liquid shown in fig. 15(a), mist of the sterilization liquid may be sent upward from the sending-out port 1 a. For example, when the outlet 1a is far from the outer edge of the flange 124, the mist of the sterilization liquid may be sent upward.

In the present embodiment, the outer shape of the guide member 25 (second unit 20) is rectangular in plan view, but the outer shape of the guide member 25 (second unit 20) is not particularly limited. Fig. 15(b) is a view showing another modification of the bacteria-removing liquid scattering device 1 according to embodiment 1. As shown in fig. 15(b), the guide member 25 (second unit 20) may have a circular outer shape in plan view. In the case where the guide member 25 has a circular outer shape, screw grooves may be formed on the inner surface of the guide member 25 and the outer peripheral surface of the flange portion 124 of the support body 12 so as to correspond to each other. That is, the second unit 20 may be rotated to support the guide member 25 on the flange portion 124 of the support body 12.

In the present embodiment, the main body 121 of the support body 12 has a rectangular shape in plan view, but the external shape of the main body 121 is not particularly limited. For example, as shown in fig. 15(b), the main body 121 may have a circular shape in plan view.

[ embodiment 2]

Next, embodiment 2 of the present invention will be described with reference to fig. 16. However, the description of the different matters from embodiment 1 is omitted, and the description of the same matters as embodiment 1 is omitted. The electrode pair 22 in embodiment 2 is different from that in embodiment 1 in position.

Fig. 16 is a sectional view of the sterilizing liquid scattering device 1 according to embodiment 2. As shown in fig. 16, the second unit 20 includes a support member 26 connected to the inner side surface of the housing portion 21. The support member 26 supports the electrode pair 22. Specifically, the support member 26 supports the electrode pair 22 such that the electrode pair 22 is positioned directly above the ultrasonic wave generating element 23. The electrode pair 22 is positioned directly above the ultrasonic wave generating element 23, and thereby ultrasonic vibration can be applied to the sterilizing fluid between the two electrodes constituting the electrode pair 22.

The description above is directed to embodiment 2. According to embodiment 2, ultrasonic vibration can be applied to the sterilizing liquid between the two electrodes. Therefore, the sterilizing fluid between the two electrodes can be oscillated, and the adhesion of the silver colloid to the electrodes can be suppressed.

[ embodiment 3]

Next, embodiment 3 of the present invention will be described with reference to fig. 17 and 18. However, the description is different from the embodiments 1 and 2, and the description of the same matters as those in the embodiments 1 and 2 is omitted. The sterilization component in embodiment 3 is different from those in embodiments 1 and 2. Specifically, the sterilization component of embodiment 3 is sodium hypochlorite.

Fig. 17 is a front view of the sterilizing liquid scattering device 1 according to embodiment 3. As shown in fig. 17, in embodiment 3, the main body 121 of the support body 12 includes a salt inlet 123. Specifically, the inlet 123 is a through hole penetrating the wall 121b of the main body 121. When the user introduces salt through the introduction port 123, the salt falls into the storage section 21. The salt to be introduced preferably includes a block-like material having a shape that can be easily introduced through the inlet 123. For example, the salt is preferably rock salt or salt granules.

Fig. 18 is a sectional view of the sterilizing liquid scattering device 1 according to embodiment 3, in the present embodiment, the electrode pair 22 includes two platinum electrodes, and as described with reference to fig. 17, when a user injects salt from the injection port 123, the salt falls into the storage section 21 and dissolves in the water L, and when the electrode pair 22 is energized in a state where the salt is dissolved (dissolved) in the water L, chlorine-based sterilizing components are generated, and more specifically, the electrode pair 22 is energized and electrolyzed, whereby sodium hypochlorite is generated.

Next, the operation of the sterilizing liquid scattering device 1 according to embodiment 3 will be described with reference to fig. 11, 17, and 18. The user introduces a predetermined amount of salt from the inlet 123 before the start of the sterilization operation. Thereafter, the user presses the sterilization button 34 of the operation unit 30 to cause the sterilization liquid scattering device 1 to perform a sterilization operation.

When receiving a signal from the operation unit 30 to instruct the start of the sterilization operation, the controller 220 drives the control valve 15 to inject a predetermined amount of raw water L into the storage unit 21 to dissolve the salt, and the amount of salt added is preferably 0.1 wt% to 5 wt%.

When a platinum-coated titanium electrode having a diameter of 1mm and a length of 30mm is used for each electrode constituting the electrode pair 22, the inter-electrode distance is 3mm, 1g of salt is charged into the storage part 21, and 100ml of raw water L is injected into the storage part 21, in other words, when the salt is added in an amount of 1% by weight, a voltage of DC5V is applied to the electrode pair 22, and a current of 150mA to 170mA flows between the electrodes to perform electrolysis, so that the concentration of hypochlorous acid increases, and about 10ppm of sodium hypochlorite can be generated by electrolysis for about 1 minute.

Specifically, hydrogen ions (H) are generated at the anode of the electrode pair 22⁺). Oxygen gas and chlorine gas are generated (formula (1) and formula (2)).

H₂O→(1/2)O₂↑+2H⁺+2e^-… type (1)

2Cl→Cl₂+2e^-… type (2)

Chlorine gas is readily soluble in water, and is converted into hypochlorous acid and hypochlorite ions in water as shown in formulas (3) and (4).

Therefore, by performing electrolysis, sterilized water having an increased sodium hypochlorite concentration can be produced. The concentration of sodium hypochlorite is preferably 5ppm or more and less than 50ppm of the available chlorine concentration. The reason why the effective chlorine concentration is preferably 5ppm or more is that the minimum concentration at which sporogenous fungi such as mold can be sterilized in a free state is 5 ppm. The reason why the effective chlorine concentration is preferably less than 50ppm is that when the effective chlorine concentration is 50ppm or more, chlorine odor is likely to be perceived from the mist of the sterilization liquid.

After the electrode pair 22 is energized, the controller 220 generates ultrasonic waves from the ultrasonic wave generator 23 as described in embodiment 1. Further, the control device 220 drives the fan motor 212 to generate air for blowing the mist of the sterilization liquid. As a result, the mist of the sterilization liquid is sent out from the sending-out port 1 a.

The description above is directed to embodiment 3. According to the present embodiment, the hypochlorous acid water can be atomized by the ultrasonic device, and the mist of hypochlorous acid water can be sent out from the outlet port 1a through the guide surface 251 by the air blowing from the air blowing device 210 (fig. 2). Therefore, as in embodiment 1, the sterilizing liquid can be uniformly attached to the faceplate 101, the ceiling surface SS, and the wall surface WS without being deviated to a specific range.

In the present embodiment, the mode of feeding the salt from the feeding port 123 is described, but the salt may be fed through the delivery port 1a described in embodiment 1.

The embodiments of the present invention have been described above with reference to the drawings. According to the present embodiment, the mist of the sterilization liquid can be blown by the blowing device 210 (fig. 2) of the bathroom environment adjusting apparatus 100. In other words, the air generated by the air blower 210 can be used for blowing the mist of the bacteria solution, and can be switched to a use other than blowing the mist of the bacteria solution. The present invention is not limited to the above-described embodiments, and can be implemented in various embodiments without departing from the scope of the invention.

For example, in the embodiment of the present invention, the bathroom environment adjusting device 100 is a bathroom heater dryer with mist sauna, but the bathroom environment adjusting device 100 may be a bathroom heater dryer, a bathroom heater, or a bathroom dryer.

In the embodiment of the present invention, the bathroom environment adjusting device 100 is provided in the ceiling portion of the bathroom, but the bathroom environment adjusting device 100 may be provided in the wall portion of the bathroom. For example, the bathroom environment adjusting apparatus 100 may be provided at an upper portion of the wall portion.

In the embodiment of the present invention, the guide surface 251 guides the mist of the sterilizing liquid to the ceiling surface SS of the bathroom, but the guide surface 251 may guide the mist of the sterilizing liquid to the wall surface WS of the bathroom.

Although the float switch is exemplified as the water level sensor 24 in the embodiment of the present invention, the water level sensor 24 is not particularly limited as long as it can detect the water level of the sterilizing fluid. For example, a distance measuring sensor or a weight sensor may be used as the water level sensor 24.

In the embodiment of the present invention, the electrode pair 22 is provided in the second cell 20, but for example, as shown in fig. 19, the electrode pair 22 may be provided in the first cell 10, fig. 19 is a cross-sectional view of the bacteria-removing liquid spreading device 1 of another embodiment, in the bacteria-removing liquid spreading device 1 shown in fig. 19, the first cell 10 includes the support member 16 that supports the electrode pair 22, the support member 16 protrudes from the first cell 10, and the electrode pair 22 is immersed in the water L or the bacteria-removing liquid.

In the embodiment of the present invention, the guide surface 251 is a flat inclined surface, but the guide surface 251 may include a curved surface as shown in fig. 20, for example. Fig. 20 is a sectional view of another device 1 for spreading a disinfectant solution according to another embodiment.

In the apparatus 1 for spreading a sterilized solution shown in fig. 20, the housing portion 21 includes a side wall which expands inward, and this side wall functions as a guide member 25. In other words, the inner surface of the side wall of the housing portion 21 functions as the guide surface 251. In addition, in the device 1 for spreading an antibacterial solution shown in fig. 20, the support member 122 detachably supports the housing portion 21.

In the embodiment of the present invention, the guide surface 251 is an inclined surface, but the guide surface 251 may include a vertical surface. For example, in the case where the bathroom environment adjustment device 100 is installed on a wall surface of a bathroom, the guide surface 251 may include a vertical surface parallel to the wall surface WS of the bathroom. In this case, the mist of the sterilizing liquid is sent upward from the guide surface 251 and flows along the wall surface WS of the bathroom.

In the above description with reference to fig. 4, 6, 9, 16, and 18 to 20, the sterilizing liquid scattering device 1 includes the guide surface 251 for guiding the flow direction of the mist of the sterilizing liquid, but the sterilizing liquid scattering device 1 may not include the guide surface 251. For example, the housing portion 21 includes a side wall that is vertically provided and has an upper end facing the panel 101, and the mist of the sterilizing liquid may be sent out from a gap between the upper end of the housing portion 21 and the panel 101.

In the above description with reference to fig. 4, 6, 9, 16, and 18 to 20, the guide surface 251 is formed on the inner surface of the guide member 25 or the accommodating portion 21, but the guide surface 251 may be formed on the outer surface of the accommodating portion 21, for example, as shown in fig. 21. The apparatus 1 for spreading a sterilized solution shown in FIG. 21 comprises a housing part 21, an electrode pair 22, an ultrasonic wave generating element 23, and a water level sensor 24. For example, the bacteria-removing liquid scattering device 1 is supported on the panel 101 at a position other than the movable wind direction plate 102.
