Description

  The present invention relates to a toilet facility installed in a toilet room.

Conventionally, in order to deodorize and prevent mold after using a toilet in a toilet room, for example, a method of removing odor components and fungi in the air using a catalyst has been used (see, for example, Patent Document 1). ). However, the above means can remove only odor components and molds contained in the air and adhere to the wall surface, etc. Therefore, deodorization and prevention can be performed quickly and reliably after using the toilet. There was a problem that it was difficult to mold.
Japanese Patent Laid-Open No. 2003-310731

  The present invention was invented in view of the above problems, and can remove odorous components and molds adhering to a wall surface as well as air in a toilet room, quickly and reliably. An object of the present invention is to provide a toilet facility with an electrostatic atomizer capable of deodorizing and preventing mold.

  In order to solve the above problems, the present invention includes a water particle emitting part 17, a counter electrode 15 facing the water particle emitting part 17, a water supply means for supplying water to the water particle emitting part 17, A voltage applying unit that applies a high voltage between the particle emitting unit 17 and the counter electrode 15 is provided, and is held in the water particle emitting unit 17 by applying a high voltage between the water particle emitting unit 17 and the counter electrode 15. An electrostatic atomizer 10 that generates nanometer-sized charged fine particle water based on the generated water is provided, and the electrostatic atomizer 10 is provided in a toilet facility in the toilet room 1. The toilet equipment with the activating device 10 is used.

  The charged fine particle water discharged from the electrostatic atomizer 10 of the toilet facility includes active species having high reactivity, and this active species has a high effect on decomposition of odor components, sterilization of molds, and suppression of reproduction. Demonstrated. Although the active species itself has a short life span, it has a long life because it is encased in water molecules, and because it is very small at nanometer size, it floats in the air for a long time and becomes highly diffusive. The deodorizing effect by the active species, the fungicide sterilization effect and the reproduction inhibiting effect can be obtained in a wide range within 1, and furthermore, the charged fine particle water can be very small and enter the pores of the wall surface. Therefore, a deodorizing effect and an antifungal effect on odor components and molds attached to the wall surface of the toilet room 1 can also be obtained.

  Further, as the water supply means, the water reservoir portion 12 for accumulating water and the tip portion 13b are the water particle discharge portion 17, and the water in the water reservoir portion 12 is conveyed to the water particle discharge portion 17 by capillary action. It is also preferable to include an automatic supply device 40 that includes the transport unit 13 and automatically supplies water into the water reservoir 12 through a branch pipe 33 branched from the water supply pipe 32 in the toilet room 1. By doing in this way, the user does not need to replenish water regularly, and since the water supply pipe 32 provided in the toilet room 1 is used as a water supply source, no special piping structure is required. It is.

  In addition, it is preferable that the water supply means includes a condensed water generating device 60 that supplies water by condensing moisture in the air. By doing so, the user periodically supplies water. There is no need for replenishment, and the piping structure is not required because the structure obtains water based on the moisture in the air. Furthermore, it is also preferable to form the condensed water generating device 60 using the Peltier unit 52 having the cooling unit 50 for generating condensed water, and thus the condensed water generating device 60 saves space. It is possible to generate condensed water efficiently.

  Further, the toilet equipment includes an air flow path 22 having one end side serving as an air suction port 21 and the other end side serving as an air discharge port 20. The filter unit 23 is disposed in the air flow channel 22, and It is also suitable to arrange the electrostatic atomizer 10 on the downstream side. By adopting such a configuration, dust and odor components in the airflow have already been removed at the location where the charged fine particle water is discharged from the electrostatic atomizer 10 in the air flow path 22, and thus the charged fine particle Since water is prevented from adhering to the dust and the like, the scattering property of charged fine particle water is ensured. Moreover, when the dew condensation water production | generation apparatus 60 is used as the water supply means of the said electrostatic atomizer 10, it prevents that the odor component in the air dissolves in the dew condensation water produced | generated by this dew condensation water production | generation apparatus 60. It is what is done.

  Moreover, in the said toilet equipment, the human body detection sensor 41 which detects the entrance / exit to the toilet room 1, and control which starts the driving | operation of the electrostatic atomizer 10 when this human body detection sensor 41 detects the leaving of a human body It is also suitable to provide a part. Thus, deodorization and mold prevention can be effectively achieved by starting the operation of the electrostatic atomizer 10 immediately after use of the toilet where the odor concentration is highest. Still further, the control unit controls the operation mode in the initial operation period T1 from the start of operation of the electrostatic atomizer 10 to the elapse of a predetermined time, and the operation in another operation period T2 after the initial operation period T1. It is also preferable to make the mode different. By adopting such a control, the operation mode that allows quick and reliable deodorization and mold prevention immediately after use of the toilet where the odor concentration is the highest, and the operation that suppresses power consumption at times other than immediately after use of the toilet. It is possible to automatically switch to the mode, so that efficient and power-saving operation can be performed.

  The present invention can remove odor components and molds adhering to the wall surface as well as air in the toilet room, and can quickly and surely deodorize and prevent mold. There is an effect.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 1 (a) shows an example of the entire toilet facility according to the embodiment of the present invention. The toilet equipment of this example is installed in the toilet room 1, and the flush toilet unit 2 is installed on the floor surface 1a in the toilet room 1, and the side wall surface 1b standing from the floor surface 1a is installed on the side wall surface 1b. Has a hand-washing unit 3.

  The flush toilet unit 2 is obtained by mounting a local washing device 31 on a flush toilet 30. The hand-washing unit 3 includes a lower storage cabinet 4 and an upper storage cabinet 5 that can store articles therein, with a predetermined gap in the vertical direction, and a counter section on the upper surface side of the lower storage cabinet 4. 1 and the counter unit 6 is provided with a hand-washing bowl 7 and a faucet 8. On the lower surface of the upper storage cabinet 5 of the hand-washing unit 3, an electrostatic mist as shown in FIG. The conversion device unit 9 is placed above the hand-washing bowl 7 of the counter unit 6.

  The electrostatic atomizer unit 9 has an internal structure as shown in FIG. 2, and a mist of nanometer-size ions generated from the electrostatic atomizer 10 provided in the main body housing 11 constituting the outer shell ( That is, the charged fine particle water (described later) is discharged into the toilet room 1 from the air discharge port 20 opened on the front surface of the main body housing 11. The electrostatic atomizer 10 includes a tank-shaped water reservoir 12 and a transporting unit that is a rod-shaped member made of a porous body and is supported in a state where the base end portion 13a is immersed in the water in the water reservoir 12. 13, a liquid application electrode 14 that supports the transport unit 13 in the above-described state and applies a voltage to water held in the transport unit 13, and a tip portion 13 b that forms the sharp shape of the transport unit 13. The main body is composed of the counter electrode 15 disposed and a voltage application unit (not shown) for applying a high voltage between the liquid application electrode 14 and the counter electrode 15.

  The conveyance unit 13 is made of ceramic particles having a particle size of 2 to 500 μm, and is a porous member that is arranged in an open cell shape with fine holes of 1 to 250 μm between the particles. In addition, the front end 13b of the transport unit 13 is the water particle discharge unit 17 of this example, and the front half of the transport unit 13 including the water particle discharge unit 17 protrudes above the liquid application electrode 14, A base end side half of the transport unit 13, which is opposite to the water particle discharge unit 17, projects downward from the liquid application electrode 14, and a part thereof comes into contact with the water in the water reservoir 12. . Both the liquid application electrode 14 and the counter electrode 15 are formed of a synthetic resin mixed with a conductive material such as carbon or a metal such as SUS, and the counter electrode 15 is grounded.

  Thus, in a state where the transport unit 13 which is a porous material absorbs the water in the water reservoir 12 from the base end 13a side and transports it to the water particle discharge unit 17 at the tip, the liquid is applied by the voltage application unit. When a high voltage is applied between the application electrode 14 and the counter electrode 15, the water particle discharge unit 17 at the tip of the transfer unit 13 functions as a substantial electrode on the liquid application electrode 14 side, and is transferred to the water particle discharge unit 17. This causes the Rayleigh splitting described later to occur in the water. In addition, as a voltage application part, what can give the electric field strength of 500 V / mm or more (especially 700-1200 V / mm) is preferable.

  Rayleigh splitting is a phenomenon in which water that has received a large amount of energy due to high voltage exceeds the surface tension and repeats splitting. The Rayleigh splitting results in a nanometer size (for example, 10 to 30 nanometers) based on the water in the water particle discharge portion 17. Electrostatic atomization that generates charged fine particle water of particle size was made, and at the same time, active species with high reactivity (substances that became the source of deodorization and sterilization such as hydroxy radicals and superoxide) were split. Jump into the air in water. In this way, nanometer-sized charged fine particle water containing active species (hereinafter, simply referred to as mist M) is generated from the water particle emitting portion 17. Active species are very reactive and exhibit high effects in decomposing odor components, sterilizing fungi, and suppressing breeding, but on the other hand, they have the property of having a short lifetime when present alone. However, in the mist M generated by the electrostatic atomizer 10, the active species exists so as to be encapsulated in water molecules, so that the lifetime is long, and the nanometer size is very small as described above, so that air As it floats in the interior for a long time and becomes highly diffusive, it can enhance the deodorizing effect by the active species, the sterilization of fungi, and the effect of suppressing the breeding in a wide range in the space. Therefore, the deodorizing effect and the antifungal effect can be obtained for odor components and molds adhering to the wall surface. Below, the deodorization reaction formula of the active species in mist M and various odor components is shown.

Ammonia: 2NH ₃ + 6 · OH → N ₂ + 6H ₂ O
Acetaldehyde: CH ₃ CHO + 6 · OH + O ₂ → 2CO ₂ + 5H ₂ O
Acetic acid: CH ₃ COOH + 4 · OH + O ₂ → 2CO ₂ + 4H ₂ O
Methane gas: CH + 4 · OH + O ₂ → CO ₂ + H ₂ O
Carbon monoxide: CO + 2 · OH → CO ₂ + H ₂ O
Nitric oxide: 2NO + 4 · OH → N ₂ + 2CO ₂ + 2H ₂ O
Formaldehyde: HCHO + 4 · OH → CO ₂ + 3H ₂ O
In the above deodorization reaction formula, .OH represents a hydroxy radical.

  In the main body housing 11 in which the electrostatic atomizer 10 is housed, an air flow path 22 is formed with one end side being an air suction port 21 and the other end side being an air discharge port 20. In addition, a filter unit 23 is disposed at the air inlet 21 portion in the air 22, and a fan 24 is disposed at a position downstream of the air outlet 20 by a predetermined distance from the air inlet 21 side to the air outlet 20 side. The air is forced to flow toward The electrostatic atomizer 10 emits the mist M to a location P in the air flow path 22 that is downstream of the filter unit 23 and the fan 24 and upstream of the air discharge port 20. The air passage 22 is disposed below the air passage 22 in the main body housing 11.

  Therefore, when the fan 24 and the electrostatic atomizer 10 are driven by a control unit (not shown) provided in the electrostatic atomizer unit 9, the air with the filter unit 23 opened on the front surface of the main body housing 11. Air in the toilet room 1 is introduced into the air flow path 22 from the suction port 21 in a state where dust, suspended particulates, and odor components are removed by the filter unit 23, and then released from the electrostatic atomizer 10. The mist M is returned to the toilet room 1 from the air discharge port 20. At this time, as described above, the mist M that is very small and can float for a long time and has high diffusibility travels to every corner of the toilet room 1 by riding on the air flow generated from the air outlet 20 toward the outside. It exhibits deodorizing effect, fungi sterilization and breeding suppression effect in the entire space in the toilet room 1, and further penetrates into the pores on the wall surface of the toilet room 1 and adheres to the wall surface. It also exerts a deodorizing effect on fungi and a fungus sterilization and breeding suppression effect. In addition, since the electrostatic atomizer 10 is arranged downstream of the filter unit 23 in the electrostatic atomizer unit 9, dust in the airflow at the location P where the mist M in the air flow path 22 is discharged. Therefore, the mist M is prevented from adhering to the dust and the like so that the mist M can be dispersed.

  In this example, as a water supply means for supplying water to the water particle discharge part 17, the tank-like water reservoir part 12 for storing water and the tip part 13b are the water particle discharge part 17, and the capillarity causes It has a structure including a transport unit 13 that transports the water in the water reservoir 12 to the water particle discharge unit 17, and further automatically supplies water into the water reservoir 12. A supply device 40 is installed. The automatic supply device 40 is branched from a water supply pipe 32 disposed in the toilet room 1 to supply water to the flush toilet unit 2 and the hand-washing unit 3, and has a water reservoir 12 at the tip thereof. A branch pipe 33 having a water supply port 33a for supplying water, an on-off valve 34 arranged in the middle of the flow path of the branch pipe 33, and a water level sensor 35 for detecting the water level in the water reservoir 12, The on / off valve 34, which is an electromagnetic valve, is controlled to open / close by the control unit of the activating device unit 9 based on the detection result of the water level sensor 35. Normally, the on / off valve 35 is held in a closed state and the water reservoir 12 When the water level falls below a certain level, the on-off valve 34 is switched to the open state for a certain period of time based on a signal from the water level sensor 35 that detects this, and a certain amount of water is supplied into the water reservoir 12. It has a structure. By installing the automatic water supply apparatus 40, the user does not need to replenish water regularly, and since the water supply pipe 32 provided in the toilet room 1 is used as a water supply source, no special piping structure is required. It has become a thing.

  FIG. 3 shows drive control of the electrostatic atomizer 10 and the fan 24 in the electrostatic atomizer unit 9. This drive control is a control unit that receives a signal from the human body detection sensor 41 when the human body detection sensor 41 detects the exit of the human body in order to perform effective deodorization and mold prevention while suppressing power consumption. Starts the operation of the electrostatic atomizer 10 and the fan 24, and the operation mode within the initial operation period T1 from the start of operation of the electrostatic atomizer 10 and the fan 24 to the time point of the predetermined time, The operation mode in the other operation period T2 after the initial operation period T1 is set differently so that the operation intensity is weaker in the latter operation period T2 than in the former operation period T1. Although the human body detection sensor 41 is installed at a location between the air discharge port 20 and the air suction port 21 on the surface of the main unit 11 as shown in FIG. 1B, it can detect the entrance and exit of the human body. If it exists, you may install in other places.

  Here, in the illustrated example, the initial operation period T1 is a period from the time when the exit is detected to the time when 15 minutes have elapsed, and during the initial operation period T1 immediately after the use of the toilet, the fan 24 has an air flow rate of 200 L / min. The electrostatic atomizer 10 is operated in the “strong” operation mode in which the drive control is performed so that the energization rate is 100%. Then, during another operation period T2, which is a period after the initial operation period T1, the fan 24 and the electrostatic atomizer 10 are stopped during the period T2a and the fan 24 so that the air flow rate is 100 L / min. And the electrostatic atomizer 10 is operated in a “weak” operation mode in which the period T2b during which the energization rate is controlled to 50% is alternately repeated every predetermined time of 120 minutes. The operation period T2 in the “weak” operation mode may be continued until the operation period T1 in the “strong” operation mode is started by the next exit detection, or when a certain time has elapsed after the start of the operation period T2. It may be set so that the operation is resumed in the “strong” operation mode when the operation itself is temporarily ended and the next exit is detected.

  By installing the operation mode immediately after using the toilet as described above in the “strong” operation mode in which a large amount of mist M is generated and the mist M is placed in a strong air current and scattered in the toilet room 1, the odor concentration is reduced. "Weak" that can quickly and surely deodorize and prevent mold immediately after use of the toilet, which is the most elevated, and suppresses the generation of mist M and airflow for scattering the mist M during periods other than immediately after use of the toilet Since it is automatically switched to the operation mode, power consumption can be suppressed. Each operation mode is not limited to the installation in the illustrated example, and other settings may be used as long as the operation mode in the initial operation period T1 is stronger than the operation mode in the other operation period T2. Absent.

  Next, another example of toilet equipment according to an embodiment of the present invention will be described. Detailed description of the same configuration as the above-described example is omitted, and only the characteristic configuration of this example is described in detail below.

  The electrostatic atomizer unit 9 of the present example incorporates the structure shown in FIG. 4 as the electrostatic atomizer 10 so that the tank-like water reservoir 12 and the automatic water supply device 40 can be mounted as in the example. The structure is unnecessary. That is, the electrostatic atomizer 10 of the present example includes a condensed water generating device 60 including a Peltier unit 52 having a cooling unit 50 and a heat radiating unit 51 as water supply means, and the cooling unit 50 of the condensed water generating device 60. It is structured to supply water by condensing moisture in the air.

  The Peltier unit 52 has a pair of Peltier circuit boards 53 having a circuit formed on one side of an insulating plate made of alumina or aluminum nitride having high thermal conductivity, facing each other so that the circuit sides face each other. The thermoelectric elements 54 arranged in parallel are sandwiched between the two Peltier circuit boards 53 and the adjacent thermoelectric elements 54 are electrically connected to each other by the circuits on both sides, and the Peltier unit power supply is connected via the Peltier input lead wire 55. When the thermoelectric element 54 is energized at 56, the one Peltier circuit board 53 (referred to as the heat absorbing Peltier circuit board 53a) to the other Peltier circuit board 53 (referred to as the heat generating side Peltier circuit board 53a). The heat absorption side Peltier circuit board 53a is connected to the cooling unit 50 and the heat dissipation side Peltier circuit board 53b is provided. Form a condensed water generating device 60 be connected to the fin-like heat radiating portion 51 side.

  The cooling unit 50 is formed in a dish shape using a material having high thermal conductivity so that the water reservoir 12 capable of storing condensed water is formed therein. On the bottom surface, there is provided a liquid application electrode 14 whose upper end portion has a sharp shape. The liquid application electrode 14 has an upper end serving as the water particle discharge portion 17 and is formed of a porous material or has a lower end by forming a fine hole or a fine groove (in the illustrated example, the fine hole 56). It is provided in a structure that functions as a transport unit 13 that transports the condensed water stored in the water reservoir 12 to the water particle discharge unit 17 at the upper end portion serving as a discharge electrode by capillary action. Further, by forming the water particle emitting part 17 with a metal or forming a metal surface film, the surface has high thermal conductivity, and the water particle emitting part 17 is thermally connected to the cooling part 50. By attaching in such a manner, condensed water may be directly generated on the surface of the water particle emitting part 17, or, as an example, it is made of a porous body and has a water particle emitting part 17 at its tip. It is good also as a structure which provides the conveyance part 13 and connects the liquid application electrode 14 to this conveyance part 13. FIG.

  When the amount of water generated per unit time in the condensed water generating device 60 exceeds the amount of water consumed per unit time in the water particle discharge unit 17, the electrostatic atomizer 10 is within the unit time. The dehumidifying effect of the toilet room 1 will also be exhibited. The cooling part 50 is provided with an overflow hole 57, and when the condensed water accumulated in the water reservoir 12 reaches a certain water level or more, excess water is disposed below through the overflow hole 57. The water storage tank 58 is drained.

  Next, still another example of toilet equipment in the embodiment of the present invention will be described. Detailed description of the same configuration as the above-described example and other examples will be omitted, and only the characteristic configuration of this example will be described in detail below.

  The electrostatic atomizer unit 9 of the present example includes an air flow path 22 in which the one end side is an air suction port 21 and the other end side is an air discharge port 20 in the main body housing 11. The filter unit 23 is disposed at the suction port 21, and the condensed water generating device 60 of the electrostatic atomizer 10 is disposed at a location downstream of the filter unit 23 in the air flow path 22. The transport unit 13, the liquid application electrode 14, and the counter electrode of the electrostatic atomizer 10 so that the mist M is discharged to a location P that is downstream from the condensed water generation device 60 and upstream from the air discharge port 20. A main body portion consisting of 15 etc. is arranged. The dew condensation water generating device 60 is composed of the same Peltier unit 52 as in the other examples, and has a structure in which the generated dew condensation water is fed into the water reservoir 12 below the transport unit 13. The filter unit 23 includes a dust collection filter 70 having a fine mesh structure for removing dust and airborne particles in the air, and a deodorization filter using activated carbon or a catalyst for removing odor components in the air. 71 and is arranged so that the deodorizing filter 71 is located downstream of the dust collection filter 70.

  In other words, in the electrostatic atomizer unit 9 of this example, the condensed water generating device 60 is disposed in the air flow path 22 so that fresh air is constantly fed into the condensed water generating device 60 to efficiently remove the condensed water. In addition, as shown in FIG. 6, the filter unit 23, the fan 24, the condensed water generation device 60, and the electrostatic atomizer 10 are arranged in this order from the upstream side to the downstream side of the air flow path 22. Therefore, the air sent by the fan 24 is in a clean state in which dust and odor components have already been removed when it is sent to the dew condensation water generation device 60, so that dust and the like adhere to the dew condensation water generation device 60. Accumulation and odor components in the air are prevented from being dissolved in the condensed water obtained by the condensed water generating device 60. When the odor component is dissolved in the dew condensation water, the mist component is also contained in the mist M generated based on the dew condensation water, but this is prevented by the above configuration. . Further, since the electrostatic atomizer 10 is positioned downstream of the filter unit 23, the mist M discharged from the electrostatic atomizer 10 is prevented from adhering to dust and the like, and the mist M is scattered. It is the same as one example to ensure the property.
