Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention provides ozone, which has a deodorizing effect, from the upper edge of the toilet bowl into and around the toilet bowl, which is normally installed in homes and offices. The present invention relates to a toilet bowl with a deodorizing device that can deodorize bad odors generated from the toilet bowl by blowing out air.

[Conventional technology]

Traditionally, to ventilate the inside of a toilet, a ventilation fan was installed on the wall of the toilet, or a large number of intake holes were installed in the toilet bowl.
A deodorizing device or the like is well known in which the bad odor inside the toilet bowl is discharged to the outside by an exhaust fan through the intake hole via the deodorizing hose.

[Problem that the invention seeks to solve]

However, among the above-mentioned known deodorizing devices, the former, which ventilates by installing a fan on the wall of the toilet, releases not only bad odors but also the warm air inside the room. The problem was that it was difficult to adopt. In addition, with the latter device that directly sucks the air inside the toilet bowl, if the device is activated while the toilet is in use,
Since airflow is generated on the surface of the buttocks to suck in bad odors, there is a problem in that when used in winter, the user feels cold.

[Means for solving problems]

Therefore, the present invention aims to solve the above problems by providing a toilet bowl that is comfortable to use while exhibiting a sufficient deodorizing effect even in extremely cold regions. The point is that a large number of ozone discharge ports are formed, and ozone, which has a strong deodorizing effect, is released from the ozone discharge ports to remove bad odors from the toilet bowl. The toilet bowl with a deodorizing device is characterized in that the gas discharge port and the ozone generator are connected through an air supply passage to discharge ozone having a strong deodorizing effect into the toilet bowl.

[For production]

In the above toilet bowl, when the ozone generator is activated when the toilet is used and ozone is released from the gas outlet at the upper edge of the toilet bowl, the interior of the toilet bowl is filled with ozone having deodorizing properties, and the chemical action of ozone causes the inner corner of the toilet bowl to Bad odors generated from objects are removed, and the toilet can always be used in a comfortable condition free of bad odors.

〔Example〕

Examples to which the present invention is applied will be described below.

FIGS. 1(A) and 1(B) are conceptual diagrams showing the basic configuration of a typical embodiment of the present invention, and as is clear from these figures, the present invention controls the operation of an ozone generator. Control circuit 1
, an ozone generator 2 operated by electric current from a control circuit section, a fan 3 that sends air generated by the ozone generator to an ozone discharge section, and a fan 3 that discharges ozone generated by the ozone generator toward the toilet bowl. The ozone discharge section 4 has an ozone discharge port 5. Therefore, the control circuit section l
The ozone generator 2 is operated by the current controlled by the ozone generator 2, and the ozone generated by the ozone generator 2 is blown to the ozone discharge part 4 by the blower 3, and is sent from the ozone discharge port 5 formed in the ozone discharge part 4 to the toilet bowl 6. released towards. The emitted ozone uses ozone's original chemical properties, that is, deodorizing and sterilizing effects, to remove bad odors generated from filth in the toilet bowl, and ozone that hits the private parts of the human body also has a sterilizing effect on the local body. become. - Next, the above basic components will be explained in detail below.

(a) Control Circuit Section The control circuit section 1 is a circuit for controlling the operation of the ozone generator, and the ozone generator is operated by the current output from this circuit. Therefore, the ozone generator operates according to the way the current flows from the control circuit section 1, and ozone is generated according to the current flow pattern.

As shown in FIG. 2, the control circuit section 1 is comprised of a sensor 7, a switch 8 that is turned on by a signal from the sensor 7, and a timer 9 that can keep current flowing for a predetermined period of time. The sensor 7 is for detecting when a person uses the toilet bowl, and includes, for example, a weight detection type sensor as shown in FIG. 2 (b). A weight detection type sensor is constructed by placing a contact point 10 via a spring 11 between the toilet seat 4' and the toilet bowl 6 of a Western-style toilet, for example. The configuration is such that the contact 10 is connected and the switch is turned on. Incidentally, it goes without saying that the weight detection type sensor may be used not only in the above-mentioned places but also in any place such as a footrest as long as the body weight can be detected. In addition to the above-mentioned sensors, it goes without saying that various types of sensors can be used, such as a sensor that detects the presence or absence of a person using the toilet using infrared rays and operates a switch. Furthermore, instead of using the above-mentioned sensor, a switch may be provided at the opening/closing part of the toilet door, and when the toilet door is opened, the timer circuit may be activated by the operation of the door switch that works in conjunction with the door. can. Additionally, when using the toilet, the user usually locks the toilet door with a key provided inside.
It is also possible to provide a switch to this key and activate a timer circuit by operating the switch in conjunction with this key.

The timer circuit 9 is for controlling the duration of the current flowing to the ozone generator, and may be of any conventional type used in various devices. A suitable device is one in which the current continues to flow for 30 minutes after the switch is turned on, and then the switch is turned off. If you use this timer, it will be 30 minutes after a person sits on the toilet seat and the switch is turned on.
Since the current continues to flow through the ozone generator for 30 minutes, the ozone generator also continues to operate for 30 minutes, emitting ozone into the toilet bowl for 30 minutes, thereby completely eliminating the odor emitted in the room.

It is of course possible to apply the intermittent circuit 9' disclosed in the ozone generator (Japanese Patent Application No. EL-258385) previously filed by the present applicant in place of the timer (
(See Figure 2 (c)). This intermittent circuit 9' is composed of an oscillator, a frequency divider, a combiner, and a transistor switch, and by setting the synchronization signal of the frequency divider to an appropriate value, a pattern as shown in FIG. 2 (d) can be created. Current can be passed intermittently to the ozone generator. Therefore, the ozone generation pattern can be freely changed by simply changing the current pattern when the current is passed intermittently.

In addition, a circuit is installed to switch the current flowing through the ozone generator between strong and weak levels, and if there is a strong odor when using the toilet, the current is increased to generate highly concentrated ozone, which removes the odor in a short time. After that, in the normal state, the current can be lowered to constantly remove the odor peculiar to the toilet. This can prevent the ozone concentration in the toilet from becoming unnecessarily high.

Furthermore, as mentioned earlier, the strength of the current is controlled in a predetermined pattern (for example, 30 minutes after the switch is turned on).
By controlling the amount of ozone generated by passing a strong current through the ozone generator for one minute and then passing a weak current through the ozone generator for 30 minutes, it is also possible to completely eliminate bad odors in the toilet. Note that the pattern of current strength is not limited to the above-mentioned pattern, and it goes without saying that various patterns can be implemented.

Although not particularly shown in the drawings, it is of course possible to provide a manual/automatic selection switch connected to the control circuit so that the user can freely select either manual operation or automatic operation. be. In this case, when cleaning the toilet bowl, for example, by operating the manual switch and continuously emitting ozone, the person cleaning the toilet bowl can be prevented from being bothered by the bad odor.

(b) Ozone generator The ozone generator 2 is a device that obtains ozone by high-pressure discharge in the air, and the device itself has been well known, but its basic configuration is as follows.
It consists of the components shown in the figure. That is, as shown in FIG. 3, the high voltage boosted by the high voltage transformer 13 connected to the power supply line 12 is supplied to the ozone generation electrode 14 through the high voltage supply line, where the high voltage is discharged and ozone is generated. It is now possible to obtain Therefore, by passing a current controlled by the control circuit described in section (a) above through the power supply line 12 of FIG. 3, ozone is generated according to the current pattern.

As an ozone generator, the ozone generator (Japanese Patent Application No. 81-2583G) filed by the applicant mentioned above is applicable.
If you use No. 5), you can freely adjust the ozone concentration. Furthermore, by providing a well-known heater circuit within the ozone generator, warmed ozone can be blown out from the discharge port, thereby eliminating the pain of using a toilet in regions with severe cold.

(c) Air blower The air blower 3 is for blowing the ozone generated by the ozone generator to the ozone outlet of the second class section of the toilet. You can use something like this, or you can use a pump to send out the air.

(d) Ozone discharge section The ozone discharge section 4 is for discharging ozone generated by the ozone generator 3 into the toilet bowl 6, and there are types shown in FIGS. 4(a) and 4(b). The ozone release part shown in Fig. 4 (a) is a Western-style toilet bowl with an ozone release port 5 formed in the seat 4, and as shown in the figure, a passage 5 for supplying ozone is formed in the seat 4. A large number of discharge ports 5 communicating with this passage are provided toward the interior of the toilet bowl 6. The discharge port 5 is
As shown in FIG. 4(b), they are formed on the inside of the toilet seat 4 in the diagonally upward, horizontal and diagonally downward directions. By forming the discharge ports in three directions in this manner, ozone is discharged toward the private parts of the human body from the discharge ports formed diagonally upward, thereby performing sterilization and deodorization of the private parts. In addition, the ozone emitted from the horizontally formed outlet forms an air curtain above the toilet bowl, which prevents the foul odor from the filth in the toilet bowl from spreading into the room, and at the same time removes the foul odor from the filth.

Further, the ozone emitted from the outlet formed diagonally downward directly deodorizes the foul odor of waste in the toilet bowl.

Although the discharge ports 5 have been described as being formed in the three directions, it goes without saying that the direction and number of the discharge ports may be changed as needed.

Further, the ozone emitting section may be formed of a tubular member having various cross-sectional shapes made of a flexible material, as shown in Figure 4 (c). By being made of flexible material, it can be adapted to both Japanese-style and Western-style toilet bowls; for example, by simply fixing the ozone emitting part around the toilet bowl using adhesive means such as double-sided tape. An ozone emitting part can be formed very easily in an existing toilet bowl or the like. Furthermore, by combining this emitting unit 4 with a portable ozone generator, a deodorizing device that can be used freely anywhere can be constructed.

By the way, the ozone release part can have the above-mentioned forms, but in addition to the above-mentioned forms, it is also possible to form a discharge port directly on the upper edge of the toilet bowl (see Figure 5), or to make it from a material other than flexible. It is a matter of course that various embodiments of the present invention, such as formed ones, are included as embodiments of the present invention.

The present invention consists of connecting the constituent parts detailed in the above sections (a) to (d) as shown in FIG.
The current controlled by the control circuit is applied to the ozone generator. The ozone generator generates ozone according to the energization pattern of the current flowing from the control circuit. The generated ozone is emitted into the toilet bowl from an ozone discharge port formed on the upper edge of the toilet seat by a fan, thereby deodorizing the inside of the toilet bowl.

〔Effect of the invention〕

As described above, according to the toilet bowl with a deodorizing device of the present invention, bad odors in the toilet bowl can be removed simply by releasing ozone having a deodorizing effect from the upper edge of the toilet bowl. In addition, by using a timer or intermittent circuit, after use,
Since ozone continues to be emitted for a while, the odor emitted in the room can be completely deodorized, and the next person will not be bothered by the odor when they use the toilet. By providing a manual or automatic selection switch, it is possible to continue emitting ozone at any time and for a required period of time. Furthermore, by incorporating a heater into the ozone generator and discharging warmed ozone from the discharge port, the toilet can be used comfortably even in regions with severe cold. Furthermore, by forming an ozone emitting part separate from the toilet bowl from a flexible material, etc., the ozone emitting part can be formed in an existing toilet bowl without modifying the existing toilet bowl, and regardless of whether it is Japanese style or style. Therefore, the toilet bowl with a deodorizing device of the present invention can be implemented very easily, and other excellent effects can be achieved.
