Definitions

  • the present invention relates to deodorizing method and apparatus capable of surely removing an offensive odor from excrements in a toilet bowl before diffusion thereof into the toilet room and capable of maintaining the deodorizing performance over a long term.
  • the following methods may be mentioned as the most orthodox means for removing the offensive odor in a toilet room: 1 a method wherein an exhaust fan is attached, for example, to the wall surface of the toilet room to discharge the inside offensive odor to the exterior, and 2 a method wherein an aromatic is placed in the toilet room to mask the offensive odor by a strong fragrance.
  • the offensive odor is not removed thoroughly.
  • the offensive odor once diffused and filled in the toilet room from the toilet bowl is discharged to the exterior of the toilet room, so the person in the toilet room is inevitably exposed to the offensive odor.
  • the offensive odor is discharged out of the toilet room, there occurs inconvenience in an area where houses stand close together.
  • no essential countermeasure is taken to destroy the offensive odor itself, but the offensive odor is to be veiled under a strong fragrance, so the person in the toilet room may rather feel repugnance to the aromatic and thus the above method 2 is not effective to persons who are sharp in the sense of smell.
  • Even the combination of this method with the above method 1 gives no solution in that it diffuses the offensive odor to the neighborhood.
  • the offensive odor components can be removed directly before diffusion from the toilet bowl into the toilet room, but since the adsorption capacity of the deodorizer has its limit and the deodorizer is exposed to the air continually, it is impossible to maintain a sufficient adsorptive deodorization performance over a long time, thus resulting in that the offensive odor components in the toilet bowl will overflow into the toilet room in a short time after the start of use. To prevent such overflow of the offensive odor components it is necessary to replace the deodorizer with a new one frequently and thus there has been a serious problem in the aspects of economy and management.
  • Fig. 1 is a schematic explanatory view showing a typical example of construction of a deodorizing apparatus according to the present invention.
  • the deodorizing apparatus indicated at 1, is composed of a deodorizing mechanism 1a and a control mechanism 12.
  • the deodorizing mechanism 1a has a casing 2 formed with two openings which are an intake port 3 and an exhaust port 11.
  • the intake port 3 and the exhaust port 11 are communicated with each other by an air passage 4 defined by a wall surface 4a.
  • the wall surface 4a is formed by a material having corrosion resistance to ozone such as, for example, stainless steel, aluminum alloy, or a synthetic resin material, provided the invention is not restricted by the material used.
  • the intake port 3 is disposed so as to face the interior of the toilet bowl, and an ozone generator 5 is disposed in the air passage 4 on the intake port 3 side, the ozone generator 5 being connected electrically to a transformer 6 (as indicated by a chain line). Between the ozone generator 5 and the exhaust portion 11 there are disposed a catalyst bed 8 and a fan 10. Where required, an adsorbent layer 9 constituted by active carbon for example is provided between the catalyst bed 8 and the exhaust port 11.
  • An example of the ozone generator 5 employs a ceramic plate. A high voltage is applied to the ceramic plate by the transformer 6 to generate ozone from the oxygen in air, which ozone is released to the air passage 4.
  • the catalyst bed 8 there are used pellets, balls or cells of any of the materials exemplified below.
  • the catalyst used in the catalyst bed 8 comprises a carrier and a metal and/or a metal oxide supported on the carrier.
  • metal and metal oxide include manganese, iron, nickel, cobalt, silver, platinum, palladium, rhodium, chrominum, molybdenum, lead, tungsten, copper, vanadium, and oxides thereof. These are used each alone or as a mixture.
  • the carrier there are mentioned alumina, silica, alumina-silica, bentonite, diatomaceous earth, silicon carbide, titania, zirconia, magnesia, cordierite, mullite, and active carbon. More preferred examples are a binary compound oxide comprising titanium and silicon, a binary compound oxide comprising titanium and zirconium,and a ternary compound oxide comprising titanium, silicon and zirconium.
  • the fan 10 is connected for rotation to an electric motor 19, whereby an air flow (indicated by a white arrow) moving from the intake port 3 side to the exhaust port 11 side is formed in the air passage 4.
  • the position of the fan 10 is not limited to that illustrated in the figure; the fan 10 may be disposed in any position if only the position is within the air passage 4. It is also possible to provide a plurality of fans on both the intake port 3 side and the exhaust port 11 side.
  • a mixing chamber 7 for mixing the offensive odor components with ozone. If a fan of low-speed rotation is provided in this position, the effect of agitation will be improved, whereby the offensive odor components decomposing effect can be improved. It is recommended, if necessary, to dispose an ozone concentration sensor 18 in an inside position before the exhaust port 11 to make control so that undecomposed ozone may not be discharged at a high concentration to the exterior of the apparatus.
  • the deodorizing action of the deodorizing apparatus 1 is as follows.
  • the air inside the toilet bowl containing such offensive odor components as ammonia and hydrogen sulfide, is conducted into the air passage 4 through the intake port 3 by a current of air formed by the fan 10, and is mixed in the mixing chamber 7 with the ozone from the ozone generator 5.
  • the offensive odor components introduced into the catalyst bed 8 together with ozone are oxidized and decomposed into odorless components, which are discharged from the exhaust port 11 into the toilet room.
  • the surplus ozone which did not decompose itself without reaction with the offensive odor components is converted back to oxygen in the catalyst bed 8, so there is no fear of leakage of a highly concentrated ozone to the exterior of the apparatus.
  • concentration of the ozone discharged from the deodorizing apparatus 1 is not higher than 10 ⁇ 6 %, it will not give unpleasant feeling to the person in the toilet room, but will give a refreshing feeling to him or her. Therefore, it is recommended to use the ozone concentration sensor 18 to control the amount of ozone to be generated from the ozone generator.
  • ozone has a sterilizing activity, so the saprophytes (e.g. cocci, actinomycetes, virus) contained in the air from the intake port 3 are sterilized in the deodorizing mechanism 1a, and the saprophytes present in the air in the toilet room are also sterilized by the ozone released in a very small amount from the exhaust port 11.
  • saprophytes e.g. cocci, actinomycetes, virus
  • the control mechanism 12 shown in Fig. 1 is for controlling ON-OFF operation of the deodorizing mechanism 1a.
  • the control mechanism 12 causes the transformer 6 and the fan 10 to operate, so that ozone is generated in the ozone generator 5 and a current of air is formed by the fan 10, whereby the deodorizing mechanism 1a is substantially operated to remove the offensive odor components.
  • the ozone concentration sensor 18 and later-described sensor 40, 40a To the control mechanism 12 are connected the ozone concentration sensor 18 and later-described sensor 40, 40a, if necessary.
  • the intake port 3 of the deodorizing apparatus 1 is disposed so as to face the inner bowl portion of the toilet bowl indicated at 20, as in later-described examples of mounting of the deodorizing apparatus 1. Then, the offensive odor components from the offensive odor source in the toilet bowl are introduced into the deodorizing mechanism 1a immediately without leakage thereof into the toilet room and treated by the following deodorizing method.
  • the volume of air to be sucked per minute in the deodorizing apparatus be set at 7 to 35 times the internal volume of the toilet bowl. An air volume below 7 times is not desirable because the offensive odor will not sufficiently be sucked into the deodorizing apparatus 1 but be diffused into the toilet room.
  • An air volume exceeding 35 times is not desirable, either, because it is too sufficient in the sense of sucking the offensive odor into the deodorizing apparatus 1, resulting in increase in the volume of air for deodorization and decrease in the deodorization efficiency, and further because a too large volume of sucked air causes the body feeling temperature during use of the toilet room to lower so the person in the same room feels cold.
  • the concentration of ozone generated be set at 0.05 to 2 ppm, preferably 0.1 to 2 ppm. If it is below 0.05 ppm, the effect of deodorization will be deteriorated, while at an ozone concentration exceeding 2 ppm there is no problem in the effect of deodorization, but there arises a waste that surplus ozone must be disposed of, and as the case may be, the surplus ozone is diffused into the toilet room in relation to the catalyst capability.
  • the catalyst bed 8 preferably has a shape in which the catalyst components exhibit a high decomposability and which exhibits a high adsorbability for the offensive odor components. Also in consideration of pressure loss and dust clogging it is most preferable that the shape of the catalyst be honeycomb. Particularly, a honeycomb shape having 100 to 400 cells per square inch is recommended. The shape of each cell of the honeycomb shape is not specially limited; for example, it may be lattice-like, triangular, hexagonal, or corrugated. For attaining a predetermined adsorbability, a larger specific surface area of the catalyst is better because the amount of the catalyst required becomes smaller resulting in that the apparatus can be reduced in size.
  • the specific surface area of the catalyst be not smaller than 50 m2/g. If the contact surface area of the catalyst per unit air volume is too small, it is likely that the effect of deodorization will become unsatisfactory, while if it is too large, there is the possibility of increased pressure loss and dust clogging. In view of these points it is preferable that the contact surface area of the catalyst at a unit air volume of 1 m3/hr be in the range of 0.01 to 0.35 m2.
  • the catalyst bed forming method is not specially limited.
  • the catalyst bed may be formed by an extrusion method or a forming method involving corrugation of ceramics paper.
  • the evolution (start) of offensive odor components is after a person sits on the seat and begins excretion. This means that the operation of the deodorizing apparatus 1 may be started simultaneously with sitting of a person on the seat. If the operation of the apparatus is stopped simultaneously with washing out of the offensive odor source or if the duration of the apparatus operation after flushing is too short, the treatment for the offensive odor remaining in the toilet bowl or the treatment for the residual offensive odor adsorbed on the catalyst will be insufficient and there is a fear of leakage of the offensive odor components into the toilet room.
  • the diffusion of a small amount of offensive odor components around the toilet bowl is unavoidable, and the offensive odor components decomposing reaction may proceed slower as will be described later, so it is preferable that the duration of the apparatus operation be not shorter than 1 minute, more preferably not shorter than 3 minutes, after washing out of excrements.
  • the operation time of the deodorizing apparatus after the use of the toilet room is within 15 minutes.
  • the adsorbed residual offensive odor components can be removed completely by continuously generating ozone in a larger amount than the amount required for decomposing the undecomposed offensive odor components.
  • the catalyst bed 8 is desired to have not only the function as catalyst but also excellent adsorbability.
  • the volume of sucked air in the above description is based on the internal volume of such a toilet bowl 20 as shown in Figs. 2 and 10. But, in toilet bowls of the type shown in Figs. 6 and 8, the same sucked air volume range as above is applied on the basis of the internal volume of an adaptor 30 or that of an inner bowl 35 shown in Fig. 7.
  • FIG. 2 shows an example of mounting of the deodorizing apparatus 1 having the internal structure shown in Fig. 1.
  • the deodorizing apparatus 1 is attached to a seat 21 which is mounted on a toilet bowl 20 for opening and closing through hinge pieces 24 and 25.
  • a downward opening portion 29 on the bottom side of the seat 21 is formed a downward opening portion 29 in a corresponding relation to a cavity portion 23 extending along the entire circumference.
  • rubber pedestals 26 intermittently to form air flowing gaps between the bottom of the seat 21 and the top of the toilet bowl 20.
  • the cavity portion 23 is in communication with the intake port 3 of the deodorizing apparatus 1, which apparatus is fixedly attached to a side edge part of the seat 21.
  • the air containing offensive odor components in the toilet bowl 20 flows in the arrowed direction and is sucked into the deodorizing apparatus 1 successively through the toilet bowl 20, opening portion 29, cavity portion 23 and intake port 3, where it is deodorized.
  • Fig. 4 shows another example of mounting of the deodorizing apparatus 1, in which a seat 21 is formed in the same manner as in the above example shown in Fig. 2, and a pivot shaft 27 of the seat 21 is in communication with the cavity portion 23.
  • the pivot shaft 27 is provided for supporting the seat 21 so that the seat can be opened and closed with respect to the toilet bowl 20. It has openings at both ends thereof, which are fitted in a communication pipe 28 through packings 27b.
  • the communication pipe 28 is formed integrally while being bent at right angles, to which bent portion is connected the intake port 3 of the deodorizing apparatus as shown in Fig. 5. Therefore, the air in the toilet bowl 20 is introduced into the deodorizing apparatus 1 through the opening portion 29 of the seat 21, cavity portion 23, pivot shaft 27, communication pipe 28 and intake port 3, as indicated by arrows.
  • Fig. 6 shows an example of application to another shape of a toilet bowl, in which, above a toilet bowl 20a with an opening formed in a stepped floor surface, there is disposed a removable, hollow stool 30 so as to cover the toilet bowl 20a.
  • a seat 21 On the hollow stool 30 is formed a seat 21 and the deodorizing apparatus 1 is attached directly to the seat 21.
  • the intake port 3 and the interior of the hollow stool 30 are communicated with each other.
  • FIG. 7 shows a portable toilet bowl (a temporary toilet bowl for indoor use) 20b, in which window holes communicating with an inner bowl 35 are formed in the lower portion of the seat 21 and an annular cavity 23a is formed behind the window holes 31 so as to be connected to the window holes, with the intake portion 3 of the deodorizing apparatus 1 being connected to part of the cavity 23a.
  • the air in the inner bowl 35 is introduced into the deodorizing apparatus 1 through the window holes 31, cavity 23a and intake port 3.
  • Fig. 8 shows an application example of the present invention to a hollow stool 30 disposed above a toilet bowl 20a which is provided on the floor surface.
  • an annular cavity 23a On the bottom side of a seat 21 there is formed an annular cavity 23a, and an opening portion 29a is formed downwards of the cavity 23a so as to face the interior of the hollow stool 30. Further, the intake portion 3 of the deodorizing apparatus 1 is communicated with the cavity 23a, which apparatus is disposed integrally with the hollow stool 30.
  • Fig. 9 shows a further example of mounting of the deodorizing apparatus 1, which is disposed on the floor surface through legs 14.
  • a joint portion 36 which is in communication with a cavity portion 23, and a hollow pipe 13 is connected to both the intake port 3 of the deodorizing apparatus 1 and the point portion 36. Therefore, the air in the toilet bowl 20 passes through the opening portion 29, cavity portion 23, joint portion 36, hollow pipe 13 and intake port 3 and is introduced into the deodorizing apparatus 1.
  • the hollow pipe 13 be formed using a bendable material having soft elasticity or formed bellows-like.
  • Fig. 11 shows a deodorizing apparatus 1 which is easy to be attached to and detached from a toilet bowl 20.
  • a hook-like hollow pipe 13 To an intake port 3 of the deodorizing apparatus 1 is bonded a hook-like hollow pipe 13.
  • the pipe 13 is formed of hard material (e.g. a rigid plastic or a metallic material) having a strength sufficient to support the whole of the deodorizing apparatus, and packings 17 having soft elasticity are attached to the concave portion of the hook-like hollow pipe.
  • a distal end 13a of the hollow pipe 13 is disposed so as to face the interior of the toilet bowl 20, preferably in a position not impeding the opening and closing of the seat 21 nor impeding the sitting and leaving of the person in the toilet room, for example, a side part of the toilet bowl 20, as shown in Fig. 10.
  • the numeral 16 in Fig. 11 denotes a supporter used to assist supporting and fixing the deodorizing apparatus 1.
  • the supporter 16 is provided where required.
  • a casing 2 is provided with a cover 15 capable of being opened and closed, it will become easier to replace the catalyst bed 8 or the adsorbent layer 9 with a new one.
  • Fig. 12 shows a still further example of mounting of the deodorizing apparatus 1, which is disposed on top of a flush tank 31.
  • the flush tank 31 is connected to a toilet bowl 20 through a water pipe 33 and also connected thereto through an overflow line 32 for the drainage of surplus water in the flush tank. Therefore, if an upper space 31a of the flush tank 31 and the intake port 3 of the deodorizing apparatus 1 are communicated with each other, the interior of the toilet bowl 20 and the deodorizing apparatus 1 are brought into communication with each other through the overflow line 32, whereby the air in the toilet bowl 20 can be fed to the deodorizing apparatus 1 as indicated by arrows.
  • the duration required for deodorization in a flush toilet is from the time when a person sits on the seat until when the offensive odor source is washed out and residual offensive odor components are treated completely, as previously noted. Therefore, it is recommended to use the control mechanism 12 for operating the deodorizing apparatus for only a required time without waste.
  • the control mechanism 12 is disposed inside or outside the deodorizing apparatus 1, and a sensor 40 attached to the seat 21 and the control mechanism 12 are interconnected electrically or optically.
  • An example of the sensor 40 is composed of a light emitting element 40a and a light sensing element 40b, as shown in Fig. 16.
  • the sensor 40 is a reflection type sensor adapted to emit light upwardly of the seat 21.
  • the emitted light beam is set at a length longer than the distance at which the sitter with the hip rising slightly (several centimeters) from the seat 21 is irradiated and shorter than the distance to the outer edge of the seat 21.
  • the sensor 40 is constructed so that the level at which the light emitted from the light emitting element 40a is reflected by the sitter and sensed by the light sensing element 40b, is detected by a sensed light level detecting circuit and the output of the detecting circuit is delivered to the control mechanism 12.
  • the sensor 40 is attached to the seat 21, it may be mounted to another portion, e.g. the toilet bowl 20.
  • the control mechanism 12 is connected to both the deodorizing mechanism 1a and a solenoid valve 34 in the flush water supply system of the toilet bowl.
  • the control mechanism 12 receives from the sensor 40 a detected signal indicative of the presence of a sitter on the seat 21, it provides an output signal to the deodorizing mechanism 1a. Further, when it is detected by the sensor 40 that the sitter is no longer recognized, the control mechanism 12 provides an output signal to the solenoid valve 34 and at the same time continues to provide output signals to the deodorizing mechanism 1a only for a certain preset time under the operation of a timer.
  • the timer is set to a time during which the drainage by the solenoid valve 34 is completed and after the lapse of a certain time the deodorizing mechanism 1a stops operation. In order that the person next entering the toilet room may not smell an offensive odor, the timer set time is at least 1 minute, preferably 3 to 15 minutes.
  • Fig. 15 is a flowchart showing an example of operation of the deodorizing mechanism 1a and the solenoid valve 34 by the sensor 40, in which the above ON/OFF controlling operations are shown successively.
  • the sensor 40 comprising the light emitting element 40a and the light sensing element 40b is preferably of the type in which it is attached to the upper surface of the toilet bowl 20 or to the seat 21 to detect whether the thigh of a person is on the seat 21 or not.
  • the sensor 40 may be of another type in which it is mounted in any position such as, for example, the flush tank 31 or the wall surface of the toilet room to detect a person entering or leaving the toilet room.
  • a seat pressure sensor 41 attached to the seat 21 to detect sitting or leaving of a person.
  • an infrared sensor or a limit switch as means for detecting sitting and leaving of a person.
  • the mounting position of the deodorizing apparatus 1 is not limited to that shown in Fig. 13.
  • the apparatus 1 may be disposed on the floor surface if only the sensor (40 or 41) and the solenoid valve 34 for the supply of water are connected electrically or optically to the control mechanism 12 disposed within the deodorizing apparatus 1. This is also applicable to the deodorizing apparatus 1 mounted as shown in Figs. 4, 8 and 11.
  • the deodorizing treatment can be continued from the time when a person sits on the seat until when a certain time is elapsed after leaving, and during the deodorizing treatment the offensive odor source can be washed out by automatic drainage; further, the remaining offensive odor after use can be eliminated completely. Consequently, the deodorization can be completed before the next person enters the toilet room.
