Description

  The present invention relates to a toilet deodorizing apparatus that removes malodorous components present in a toilet bowl with mist.

  Conventionally, as a deodorizing device for deodorizing a toilet with mist, the odor in the toilet is sucked into the deodorizing chamber through the odor duct, and the cleaning water in the tank of the cleaning water supply system is sprayed from the nozzle portion into the deodorizing chamber. The odor and water mist are mixed and contacted, ammonia and other malodorous components in the odor are adsorbed by water, and the water that has adsorbed the malodorous components is collected from the deodorizing chamber through the drain duct into the tank and deodorized air. Is exhausted from the exhaust port. (For example, refer to Patent Document 1).

  FIG. 6 shows a configuration diagram of a toilet deodorizing apparatus described in the publication. Wash water for washing the toilet 1 is stored in a tank 2, and a wash water supply path 3 connecting the tank 2 and the toilet 1 is provided. When supplying wash water into the toilet 1, the wash water in the tank 2 is supplied into the toilet 1 through the wash water supply path 3, and flows into the sewer through the drain pipe 1a. Then, the wash water is stored in the tank 2 through a water pipe (not shown).

  On the other hand, it has an odor suction port 4 opened in the toilet 1 and communicates with the odor air supply duct 5. A fan device 6 is disposed in the middle. And the deodorizing apparatus A which performs a deodorizing is connected to the downstream end part of the odor supply duct 5.

However, in the conventional configuration, since the mist is sprayed by the nozzle, the particle size is as large as several tens of μm. For this reason, when the mist is sprayed directly into the toilet, which is the source of odor, the buttock gets wet. Therefore, the odor removal by mist cannot be performed directly in the toilet bowl, and the deodorization chamber 8 must be separately provided as in the conventional configuration to deodorize.
Therefore, there has been a problem that the apparatus becomes large.

  Moreover, since the particle diameter of mist is as large as several tens of μm, the frequency of contact with odor is low, and mist is difficult to diffuse. For this reason, sufficient deodorization could not be performed.

  The present invention solves the above-mentioned conventional problems, and since the buttock does not get wet even if deodorization in the toilet bowl is performed with mist, the odor in the toilet bowl can be directly removed with mist, so that the deodorization performance is improved. An object of the present invention is to provide a toilet deodorizing apparatus which can be improved and space-saving.

  In order to solve the above-mentioned conventional problems, the toilet deodorizing apparatus of the present invention includes a fine atomization means for atomizing a liquid into a fine mist, and the fine mist generated by the fine atomization means is contained in a toilet bowl. It is intended to be released to

  As a result, fine mist having a particle diameter of several hundreds of nanometers atomized by the fine atomization means can be sprayed into the bowl of the toilet bowl. Therefore, as the particle size becomes smaller, the adhesive force becomes smaller and the buttock does not get wet, so the odor in the toilet can be removed directly with fine mist, improving the deodorizing performance and providing a dedicated deodorizing chamber. There is no need to save space.

  The toilet deodorizer of the present invention can improve the deodorizing performance and save space.

  1st invention is equipped with the fine atomization means which atomizes a liquid into a fine mist, and discharge | releases the fine mist produced | generated by the said fine atomization means in the toilet bowl of a toilet bowl, and has a particle size of several hundred nanometers. Mist comes in contact with ammonia and other malodorous components in the odor present in the bowl of the toilet bowl, and the malodorous components are adsorbed by the water and discharged to the outside together with the wash water and stored water of the ball to remove the malodor. Thus, the odor of the toilet bowl can be effectively removed, and the fine mist has a very small particle size, so that the adhesive force is reduced and the buttock is not wetted so that it can be used comfortably. Further, since it is possible to remove odor by spraying fine mist directly into the bowl of the toilet bowl, it is not necessary to provide a dedicated deodorizing chamber, so that space can be saved.

  The second invention particularly generates the fine mist by atomizing the fine atomizing means of the first invention, atomizing means for atomizing the liquid into a small diameter mist, and the small diameter mist atomized by the atomizing means. In the atomization means, the liquid is atomized into a small mist with a particle diameter of several tens of μm, and the atomization means refines the liquid into a fine mist with a particle diameter of several hundreds of nanometers. As a result, the load on each atomizing means and atomizing means can be reduced and the functions provided by each can be maximized, resulting in an increase in the amount of atomized fine mist. And the deodorizing effect can be enhanced.

  In the third invention, in particular, in the first or second invention, by making the particle diameter of the fine mist 1 μm or less, the contact area between the fine mist and the malodorous component of the odor can be increased, and the deodorizing effect is improved. In addition, since the adhesive force of the fine mist is reduced, it is possible to reduce the wetness of the buttocks and to provide a comfortable deodorizing device.

    In the fourth aspect of the invention, in particular, the atomizing means of the second or third aspect of the invention is configured to atomize the liquid with a pressurized or negative pressure nozzle, so that a simple design is possible. Moreover, since mist can be sprayed with a large amount of atomization, deodorizing performance can be improved.

  In the fifth aspect of the invention, in particular, since the atomizing means of the second or third aspect of the invention has a configuration in which an ultrasonic vibrator is provided at the bottom of the storage tank, the number of small-diameter mists introduced into the finer means is small. Since the particle size can be as small as μm, the miniaturization can be performed with low energy.

  In the sixth invention, in particular, the atomization means according to any one of the second to fifth inventions is made by atomizing the small-diameter mist atomized by the atomization means by corona discharge. Since the atomized mist can be given a charge and refined by its repulsive force, the atomized mist is charged and thus can prevent aggregation. In addition, a compact design is possible.

  The seventh invention, in particular, comprises the discharge means for charging the small-diameter mist atomized by the atomization means with the finer means of the sixth invention, and a power supply part for supplying a voltage to the discharge part, Since the discharge portion is composed of a grounded cylindrical electrode and a rod-shaped electrode that applies a high voltage disposed in the central shaft portion of the tubular electrode, the vicinity of the rod-shaped electrode has a high electric field strength. The mist introduced from the atomizing means under a low voltage can be refined by giving an electric field strength necessary for the miniaturization. Moreover, since the time exposed to an electric field can be ensured, mist can be effectively miniaturized.

  In particular, in the invention according to any one of the first to seventh inventions, the eighth invention includes use detection means for detecting use of the user's toilet, and when the use detection means detects use, a fine mist is emitted. Therefore, if the user uses a toilet bowl, the toilet deodorizer automatically releases fine mist. By operating the deodorization function reliably, the deodorizing effect is enhanced and the user's effort is saved. Can be improved.

  In particular, in the ninth invention, in particular, in any one of the first to eighth inventions, after the use detection means finishes the use detection, the fine mist is released for a predetermined time. Even after use, the toilet deodorizer operates for a predetermined time, and the odor remaining in the toilet is deodorized, so that the deodorizing effect can be further improved.

  According to a tenth aspect of the present invention, in particular, in the toilet deodorizing apparatus of the eighth or ninth aspect, the use detecting means is a seating detecting means for detecting that a user is seated on a toilet seat provided in the toilet bowl. When the seating detection means detects the seating, the toilet deodorizing device is operated, and if the user sits on the toilet seat, the deodorization can be performed automatically without the need for operation.

  In an eleventh aspect of the invention, in particular in the eighth or ninth aspect of the invention, the use detecting means is a human body detecting means for detecting a user approaching the vicinity of the toilet, so that when the user approaches the toilet, the deodorizing device is Since it operates, it can be deodorized even in a use state where it is not seated on the toilet seat when boys are used, and a wide range of use conditions can be handled.

In a twelfth aspect of the invention, in particular, in any one of the first to eleventh aspects of the invention, when the toilet seat has an openable / closable toilet lid and the toilet seat is covered with the toilet lid, the fine mist is applied for a predetermined time. By discharging, when the lid is closed, the fine mist fills the toilet bowl, and the mist containing active oxygen species adheres to the toilet seat surface.
For this reason, since the bacteria adhering to the toilet seat surface can be oxidatively decomposed, a clean toilet seat can always be maintained.

  In a thirteenth aspect of the invention, in particular, in any one of the first to twelfth aspects of the invention, it is provided with a local cleaning means for injecting cleaning water to a local part of a user, so that the liquid used for deodorizing the toilet and the local cleaning can be used. Since the washing water to be used can be shared, it is not necessary to provide means for supplying each liquid individually, and the structure can be simplified and the construction can be simplified.

  The main body 27 is provided with a local cleaning means 30, and a local cleaning nozzle 31 for spraying the local cleaning water on the local area after the stool is provided so as to be able to advance and retract behind the ball 25 of the toilet bowl 20 and used for local cleaning. As the local cleaning water, hot water obtained by heating tap water with heating means (not shown) is used, and the local cleaning water is sprayed by operating a solenoid valve (not shown).

  A fine atomizing means 32 is installed in the ball 25 in the vicinity of the rim water passage 22. As shown in FIG. 2, the fine atomizing means 32 is such that the atomizing means 33 employs a pressurized nozzle system in which high-pressure water is sprayed from the nozzles and is atomized. Is formed by an atomizing nozzle 34 that jets out as a mist-like small-diameter mist, and a finer means 35 installed at the tip of the atomizing nozzle 34. The supply of tap water is configured to control the supply and flow rate by a control valve (not shown).

  As shown in FIG. 3, the miniaturization means 35 includes a discharge unit 36 that applies a charge to the small-diameter mist atomized by the atomization nozzle 34 by corona discharge, and a power supply unit 37 that supplies a high voltage to the discharge unit 36. Yes. The discharge part 36 includes a cylindrical electrode 38 that is electrically grounded and formed of stainless steel, and a rod-shaped electrode 39 formed of tungsten provided at the center thereof. The cylindrical electrode 37 has an inlet and an outlet, and a guide 40 for introducing a small diameter mist is provided at the inlet. An atomizing nozzle 34 is inserted into the guide 40. The rod-shaped electrode 36 is electrically connected to a power supply unit 37 installed on the main body 27 and is applied with a high voltage.

  In addition, a human body detection unit 41 that detects infrared rays emitted by the user is installed on the wall surface of the toilet where the toilet 20 is installed, and the human body detection unit 41 can transmit a detection signal to the control unit 42 installed in the main body 27. It has a configuration.

  The toilet seat 20 is provided with seating detection means 43 for detecting that the user is seated. An opening / closing detection means 44 for detecting the opening / closing state of the toilet lid 29 is installed in the vicinity of the pivot of the toilet lid 29, and the seating detection means 43 and the opening / closing detection means 44 are electrically connected to the control unit 42. . In addition, the solenoid valve of the local cleaning means, the heating means, the control valve of the fine atomizing means and the like are also electrically connected to the control unit 42, and the operation of the toilet deodorizing device is controlled by the control unit 42. ing.

  About the toilet deodorizing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

First, when the user enters the toilet, the human body detecting means 43 detects the human body, and the control unit 42 that has received the detection signal starts the operation of the fine atomizing means 32, and the fine mist is contained in the ball 25 of the toilet 20. Release begins.

  As for the operation of the fine atomizing means 32, first, tap water sent at the water pressure of the tap water is sprayed from the atomizing nozzle 34, and a small mist having a particle diameter of several tens of μm is sprayed. The small diameter mist is introduced into the guide 40 of the miniaturization means 33 and flows into the cylindrical electrode 38 of the discharge portion 36.

  In the discharge unit 36, a high voltage of 5 to 10 kV is applied from the power supply unit 37 to the rod-shaped electrode 39. At this time, corona discharge occurs between the rod-shaped electrode 39 and the cylindrical electrode 37 and a high electric field state is obtained. For this reason, electric charge is given to the small diameter mist which flowed. And if the repulsive force by this electric charge exceeds the surface tension of a small diameter mist, it will split and refine.

  The refined fine mist is diffused into the balls 25 of the toilet bowl 20 in a state containing active oxygen species generated by corona discharge. And the odor in the ball | bowl 25 is capture | acquired by the fine mist which refined | miniaturized, and it oxidizes and decomposes with an active oxygen species, and deodorizes. The minute mistake is suspended in the ball 25 and then dropped and adhered to the stored water on the inner surface or bottom of the ball 25. Since the particle size of the refined fine mist is a fine mist of several hundred nm to several μm, it does not easily adhere to the user's buttocks and does not get wet. Therefore, it is not necessary to provide a separate deodorizing chamber as in the prior art, and space saving can be achieved. In addition, since the particle size is small, it is easy to diffuse and the frequency of contact with odor is increased, so that the deodorizing performance is greatly improved.

  When the user is for boys, when the user leaves the toilet, the operation of the fine atomizing means 32 is automatically stopped after a short predetermined time.

  When the user sits down and uses the stool, the user can wash the local area after the stool is finished by operating the washing button provided separately, and the washing water is sprayed from the local washing nozzle 31 to the local area. When the user leaves the toilet seat 28 after the stool operation ends, the seating detection means 43 detects the absence of the seat, and after a predetermined time has elapsed, the operation of the fine atomization means 32 automatically stops.

  In addition, when flushing the toilet bowl water to the toilet bowl 20 after stool, the toilet bowl wash water spouts from the spray port 24 of the rim water passage 22, flows down the inner surface of the ball 25 and discharges filth to the discharge port 26, and finely The odor element that adheres to the mist and falls to the stored water at the inner surface or bottom of the ball 25 is also discharged.

  Further, when the stool is finished and the toilet lid 29 is closed, the opening / closing detection means 44 detects the closing of the toilet lid 29, and the control unit 42 intermittently operates the fine atomizing means for 5 minutes per hour. Do. At this time, the fine mist diffuses into the balls 25 of the toilet bowl 20, but the toilet seat 28 is covered with the toilet lid 29, so that the fine mist also adheres to the surface of the toilet seat 28. Then, the fine mist containing active oxygen species decomposes the bacteria on the surface of the toilet seat 28. Therefore, a clean toilet seat can always be maintained. This function is executed after an operation for a predetermined time after the end of use by the human body detection means 41 and the seating detection means 43.

  As described above, the present embodiment includes the atomizing nozzle 34 that is an atomizing unit that atomizes water into a small-diameter mist, and the finer unit 35 that refines the small-diameter mist atomized by the atomizing unit. The fine mist refined by the refinement means 35 is discharged into the toilet bowl 22, and the small diameter mist having a particle diameter of several tens of μm atomized by the atomization means has a particle diameter of several hundred nm. Can be atomized into a fine mist and sprayed into the toilet bowl 20. Therefore, since the adhesive strength is reduced and the heel portion does not get wet because the particle size is reduced, the odor in the toilet 20 can be directly removed by mist, and it is necessary to improve the deodorization performance and provide a deodorization chamber by mist. There is no need to save space.

  In the present embodiment, since the human body detection means 41 and the seating detection means 43 are installed, the operation of the toilet deodorizing device can be automated, and a user-friendly deodorizing device can be provided without taking time and effort. Can be provided.

  Further, in the present embodiment, by providing the opening / closing detection means 44 of the toilet lid 29, the fine mist fills the sealed toilet 20, and the mist containing active oxygen species adheres to the surface of the toilet seat 28. Therefore, since the bacteria attached to the surface of the toilet seat 28 can be oxidatively decomposed, a clean toilet seat can always be maintained.

  In addition, in this Embodiment, although the local washing | cleaning means 30 was provided in the deodorizing apparatus for toilet bowls, this is not an essential requirement and only the deodorizing function by fine mist may be sufficient.

(Embodiment 2)
FIG. 4 shows a cross-sectional view of a toilet deodorizer according to a second embodiment of the present invention, and FIG. 5 shows a detailed cross-sectional view of the miniaturization means.

  The difference between the present embodiment and the first embodiment is that the atomizing nozzle is used in the first embodiment as the atomizing means of the fine atomizing means. However, in this embodiment, an ultrasonic transducer is used. The other configurations are the same as those of the first embodiment, and members having the same reference numerals have the same configurations, and the description thereof is omitted.

    In FIG. 4, the atomizing means 45 of the fine atomizing means of the present embodiment includes an ultrasonic transducer 48 at the bottom of a storage tank 47 having a water supply part 46 having a water level adjusting function on the side surface. The water supply unit 46 communicates with the water supply via a pipe, and tap water is supplied so that the water level is constant at a substantially central position of the storage tank 47, and the upper portion of the storage 47 tank is a hollow portion to which no tap water is supplied. 49. A discharge port 50 is provided in a portion corresponding to the cavity 49 of the storage tank 47, and a pipe 51 is connected to the discharge port 50. Further, the blower 52 installed in the main body 27 is connected to the cavity 49 through the blower pipe 53, and the air from the blower 52 is supplied to the cavity 47. As shown in FIG. 5, a discharge nozzle 54 is connected to the other end of the pipe 51, and the discharge nozzle 54 is inserted into the guide 40 of the miniaturization means 35.

  The miniaturization means 40 has the same configuration as in the first embodiment, and the discharge part 36 includes a cylindrical electrode 38 that is electrically grounded and formed of stainless steel, and a rod-shaped electrode 39 that is formed of tungsten provided at the center thereof. The rod-shaped electrode 36 is electrically connected to a power supply unit 37 installed in the main body 27, and a high voltage is applied.

  About the toilet deodorizing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the atomizing means operates as in the first embodiment, the atomizing means 45, the atomizing means 35, and the blower 52 operate in conjunction with each other. In the atomizing means 45, when the ultrasonic vibrator 48 is operated, a water column rises from the surface of the water stored in the storage tank 47, and a small-diameter mist is generated in the cavity 49 of the storage tank 47. At this time, the particle diameter of the small diameter mist is several μm. The small-diameter mist is sent from the discharge port 50 of the storage tank 47 to the pipe 51 by the air supplied from the blower 52, sprayed from the discharge nozzle 54 onto the finer means 35, and refined by the finer means 35. Deodorize by diffusing into 20 balls 25.

As described above, in the present embodiment, by adopting the ultrasonic method as the atomizing means 45, the particle diameter of the small diameter mist introduced into the finer means 35 is a few μm, which is smaller than that of the nozzle method. Therefore, since the amount of charge required for miniaturization may be small, the voltage applied to the discharge part 36 of the miniaturization means 35 can be lowered.

  Moreover, since the atomization means 45 is set so that the water level of the storage tank 47 becomes constant, it is possible to always maintain the optimum water level at which the atomization amount is maximized, so that no atomization failure occurs. Fine mist can be effectively sprayed.

  As described above, since the deodorizing device for toilets according to the present invention can be deodorized with fine mist without getting the surroundings wet, it can also be applied to applications such as a deodorizing device for toilets and the entire living space.
