Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention automatically removes ammonia odor and other deodorants in the toilet, and at the same time, emits a sound similar to the drainage sound to prevent wasteful drainage, which is a problem especially in women's toilets, and also has a sounding device useful for saving water. -It is related to the structure of the water-saving device.

[0002]

[Prior art]

 Conventionally, deodorizers and fragrances that use activated carbon have been widely used to eliminate odors such as ammonia odors in toilets, but their effects are not sufficient and the discomfort of toilet odors cannot be eliminated.

Therefore, recently, a deodorizing mechanism including an ozone generator, a fan motor, an optical sensor switch for detecting the presence or absence of a person, an electronic control circuit for operating and controlling each of the above parts, and a catalyst filter is introduced. A toilet deodorizing device housed in a storage container provided with a mouth and an exhaust port has been devised and is already on the market.

There are various shapes of this toilet deodorizing device, but the most direct mounting is the one that is locked on a Western-style toilet and sucks ammonia odor and other suspended matter that diffuses from inside the toilet with a fan motor to generate an ozone generator and a catalyst. It is designed to be decomposed and deodorized by the strong oxidizing power of ozone and exhausted through a deodorizing air passage provided with a filter.

FIG. 4 is a perspective view showing an example of use of the above conventional toilet deodorizing device.

In FIG. 4, the toilet deodorizing device 30 is locked and fixed to an edge of the main body 32 of the Western style toilet 31 via an L-shaped member 37 having an intake port in. At this time, the toilet deodorizing device 30 and the L-shaped member 37 are in positions where they do not hit the toilet seat column 39 when the toilet seat 38 is lowered, and the detection light S (broken line) of the optical sensor switch 33 is used by the person using the western-style toilet 31. It is adjusted so that it is in a position where it is blocked by a part of the body (especially the foot).

Next, inside the toilet deodorizing device 30, first, the air in the toilet along with ammonia odor and the like is sucked from the intake port and passes through the room where the ozone generator is arranged, and oxygen in the air is partially ozone. Be converted. Next, the malodorous molecules such as ammonia are adsorbed and decomposed through the inside of the catalyst filter of the lattice honeycomb structure (for example, calcium aluminate fired body with manganese oxide as the main catalyst and titanium dioxide as the adsorbent), and the fan motor The odorless air is exhausted from the exhaust port.

On the other hand, the sound of defecation during use of the toilet is the most cause of shame especially for women. The domestic toilet is exceptional, and the toilets of buildings and offices used by an unspecified number of people and public toilets are used. In that case, it is common practice to flush the water so that the defecation sound cannot be heard outside. It has the effect of quickly relieving shame.

[0009] Therefore, in the women's toilet, it is the current situation that the water is drained twice or thrice with a single use, and the water is substantially useless.

[0010]

[Problems to be solved by the device]

 Needless to say, the wasteful drainage from the toilet is a problem that should be improved in terms of saving water. It is difficult to ensure that only one drain can be used per use. This is probably a psychological problem of shame in women and cannot be solved overnight.

In this regard, there are rare toilets that have already been devised to mute sound such that music and brook babbling sounds are always played in the toilet.

[0012] However, usually, the sound of the above music level does not cover (mute) the defecation sound, but if the volume is increased, it becomes calm and complains that the toilet cannot be used. As a result, wasteful drainage from women's toilets will never cease.

On the other hand, a problem with the structure of the existing toilet deodorizing device is that the use environment is inferior to that of the electrical system because of the purpose of decomposing and deodorizing malodorous molecules such as ammonia odor in the toilet by ozone decomposition. (Ozone has a strong oxidizing power). In this respect, the deodorizing air passage and the electric system part were not completely separated from each other in the past, and the conductor part of the wiring and the soldered part are likely to be rusted or rotted, causing a failure. There is a problem in that it causes the problem and eventually shortens the life of the device.

The present invention has been made in view of the above circumstances, in which a conventional toilet deodorizing function and a new sounding mechanism for saving water are integrally housed, and an electric system section and a deodorizing air passage are internally partitioned. The purpose is to provide a toilet deodorizing and water-saving device that is separated by plates and has rust measures.

[0015]

[Means for Solving the Problems]

 The present invention includes an ozonizer that generates ozone by silent discharge, a fan motor, a first optical sensor switch that detects the presence or absence of a person, an electronic control circuit that operates and controls the above-mentioned parts, and a catalyst filter cassette. A deodorizing mechanism, a dummy sound generation electronic circuit that generates a dummy sound similar to toilet drainage sound, a speaker that outputs the dummy sound, and a sounding mechanism that includes a second optical sensor switch. The components are housed in a storage container provided with an intake port and an exhaust port into which they are detachably inserted, and at the same time, an electrical system unit consisting of the two optical sensor switches, a speaker, and an electronic control circuit board including a dummy sound generation electronic circuit is installed. Toilet deodorization characterized by being separated from the deodorizing air passage in which the ozonizer, catalyst filter cassette and fan motor are installed by an internal partition plate. By providing a water system, it is to achieve the above object.

[0016]

[Action]

 In the toilet deodorizing and water-saving device according to the present invention, since the deodorizing air passage and the electric system section are completely separated by the internal partition plate in the storage container, odors such as ammonia and ozone are directly connected to the electric wiring. Do not hit the parts or soldered parts.

Therefore, adverse effects such as rust and corrosion of the conductor wire and the soldered portion due to the ozone and the like do not occur, and the number of failures is small, and the product life is significantly extended compared to the conventional case.

In addition, a sounding mechanism that generates an artificial sound similar to toilet drainage sound for preventing wasteful drainage, which has been particularly problematic in women's toilets, is housed integrally with the deodorization mechanism. Therefore, it is possible to effectively hide the defecation sound without damaging a woman's shame, in the same way as cheating with the drainage sound that has been conventionally performed in the women's toilets, and it can be used without any discomfort.

The non-contact optical sensor switch automatically operates for deodorization and muffling, so there is almost no operational burden on the user and it is hygienic.

Further, since the deodorizing air passage and the electric system section are separated by the internal partition plate in the storage container of the main body of the apparatus, the conducting wire section and the soldering section are not affected by the odor of ammonia and ozone with strong oxidizing power during deodorization. The attached parts will not rust or rot, and the product will have a long life.

[0021] Further, since the L-shaped air inlet / cumulative locking member can be removably inserted into the air inlet of the storage container, it can be directly attached to the Western-style toilet body or attached to the toilet inner wall of the Japanese-style toilet. It is possible. That is, in the case of a Western-style toilet bowl, the locking member is attached to the toilet bowl directly, and in the case of a Japanese-style toilet bowl, the locking member is removed and the main body is mounted on the wall.

The electrical system section is characterized by a structure in which an internal partition 17 completely separates the deodorizing air passage T in which the ozonizer 1, the catalyst filter cassette 5 and the fan motor 2 are arranged. The main body of the apparatus produces and drives a DC power source of 12V to 24V through an AC adapter 19 connected to a commercial power plug.

The respective parts will be described in detail below. First, the ozonizer 1 is a device of the ozone generator by silent discharge, and generally comprises a double glass wall, and tin foil is put inside and outside thereof. Ozone is generated by applying an alternating voltage of approximately 4.8 KV to oxygen and causing silent discharge.

Next, the first and second photosensor switches 3 and 12 are both infrared switches that combine a light emitting diode of gallium arsenide and a light receiving element, and are commonly used in automatic flushing devices for men's toilets and the like. It is equivalent to the one. As shown in FIG. 3, the first optical sensor switch 3 is set so that the detection light S1 is at a position where it is blocked by the foot of the person who is using the toilet, and the second optical sensor switch 12 detects the detection light S2. It shall be placed in a position that is oriented in the lateral direction of the sitting person. Further, the first optical sensor switch 3 is preferably provided on both the left and right sides of the apparatus body (3, 3 ') so that the first optical sensor switch 3 can be attached to either the right or left side of the toilet body 32 depending on the usage conditions.

Next, the catalyst filter cassette 5 is equivalent to the above-mentioned conventional example, but more specifically, it is a lattice-shaped honeycomb structure catalyst having a wall thickness of 0.5 mm and an opening of about 2 mm, which is used as a binder. Calcium aluminate, manganese oxide (manganese nitrate, etc.) as main catalyst, copper oxide as co-catalyst, and titanium dioxide as adsorbent are used, and the shape of the fired cuboid is rectangular parallelepiped, which is easy to remove and replace.

Next, the fan motor 2 is a general-purpose fan that rotates at a DC voltage of about 12V to 24V DC and performs intake / exhaust, and the fan portion is made of a material such as ceramic or reinforced synthetic resin that is particularly resistant to corrosion. It is desirable to use the existing one.

Next, the electronic control circuit 4 for operating and controlling the above-mentioned respective parts carries out a certain control in accordance with a procedure programmed in advance by the one-chip microcomputer.

For example, when the presence of a person is detected by the first optical sensor switch 3, the fan motor 2 and the ozonizer 1 are activated to deodorize, and the person leaving is referred to as the first optical sensor switch. After 3 senses, the 1-chip microcomputer with built-in timer has a control to operate for 3 minutes to perform deodorization completely and to operate deodorization for 5 minutes every hour regardless of the presence of people. Program in ROM of (MC).

Next, the onomatopoeia generation electronic circuit 14 for generating the onomatopoeia similar to the toilet drainage sound is written in advance in the ROM as digitized voice waveform similar to the toilet drainage sound, and the information is sequentially read out and converted into an analog form. The speaker 11 is configured to generate sound by amplification. It goes without saying that the onomatopoeia generation electronic circuit 14 can also be controlled by the microcomputer chip (MC).

As shown in the block diagram of FIG. 3, the electronic control circuit 4 of the deodorization mechanism and the pseudo-sound generation electronic circuit 14 of the sound generation mechanism are mounted on one control board 15A, and the ozonizer 1 is silent discharge. Since it is necessary to apply a high voltage, it is desirable that the high voltage wiring section 18 be provided separately from the normal voltage circuit and provided with a separate high voltage substrate 15B.

Next, the internal partition plate 17 is a toilet bowl inside the storage container 9 so as to completely separate the deodorizing air passage T in which the ozonizer 1, the catalyst filter cassette 5 and the fan motor 2 are arranged from the electric system part. The air passage T on one side and the opposite side are completely bisected, and only a small amount of insulating coating wire for wiring is passed through a small hole provided appropriately, and ammonia odor, ozone, etc. There is no possibility of flowing into the electric system section side through the partition plate 17. The inner partition plate 17 is made of a synthetic resin plate or an aluminum plate having a thickness of about 1.5 mm, and in the embodiment, the ventilation passage T where the fan motor 2 is located is enlarged so that the fan motor 2 having a high suction force can be folded. It's tuned.

Next, the storage container 9 is made of synthetic resin, and can be divided into two parts on the side of the electric system and the side of the ventilation path T, and is screwed at several places. In addition, a large number of small holes p are provided in the portion corresponding to the speaker 11, the intake port in is provided in two directions (in1, in2), and the L-shaped intake port / locking member 21 is provided in the intake port in1 on the air passage side. Since it is removably inserted without being attached, it can be locked and fixed to the edge of the western-style toilet body 32 as shown in FIG. In this case, in FIG. 1, the bad odor in the toilet bowl flows through the deodorizing air passage T as indicated by the arrow F through the intake port in of the locking member 21.

Incidentally, as a reminder, this device is not limited to the Western-style toilet bowl as in the above-mentioned embodiment, but can be used in a Japanese-style toilet bowl by removing the locking member 21 and hanging it. The flow of ventilation in this case is as shown by the broken line arrow F'through the intake port in1 in FIG.

As described above, the toilet deodorizing and water-saving device 10 according to the present invention has an ozone deodorizing function and a drainage sound-like onomatopoeic sound generating function for making the defecation sound inaudible. Since it operates almost automatically by the switch and microcomputer control, it is accepted by the user without any resistance, and the two effects of water saving can be obtained at the same time by removing the stench of the toilet and preventing wasteful drainage.
