Abstract

PURPOSE:To effectively deodorize by setting a frequency with a control circuit so that the amount of ozone generated from an ozone generator is always constant even though moisture and temperature change. CONSTITUTION:An outside air temperature is detected with a moisture and/or an outside air temperature sensor 1 and a detection signal is inputted into a control circuit section 2. The control circuit 2 controls the frequency or the pulse duty ratio of a high voltage generated from a high voltage generation circuit based on a moisture and/or an outside air temperature signal so that the amount of ozone generated from an ozone generating section 5 is always constant independent of changes of the moisture and the outside air temperature. The high voltage generation circuit amplifies a pulse signal from the control circuit section to be converted into a high voltage. An ozone generator 5, a catalyst 6 and a fan 9 are housed in an air tunnel 4. Air smelling bad is sucked through the fan 9 from an air suction port 7 provided at one end of the air tunnel, mixed with the ozone generated from the ozone generator 5 to enter the catalyst 6 and reaction between a malodorous component and the ozone is promoted under the action of the catalysis 6 to accomplish deodorization. Clean air deodorized is discharged into a room through an exhaust port 8 provided at the other end of the air tunnel.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a deodorizing device for toilet bowls that is installed in places where bad odors are generated, such as toilets, to deodorize them.

As a deodorizing device installed in places that generate bad odors, such as toilets,
Applying a pulsed high voltage generated by a high voltage generation circuit to an induction electrode and a discharge electrode to cause a creeping discharge on the surface of the discharge electrode,
BACKGROUND OF THE INVENTION Ozone deodorizing devices have been known that decompose malodorous components by decomposing odor components under the action of a catalyst using ozone generated by an ozone generator that generates ozone by converting surrounding oxygen into ozone. Japanese Patent Publication No. 58-8004
No. 0 discloses a toilet device in which a deodorizing device having this configuration and a fragrance generating device are arranged in this order.

By the way, if the frequency of the high pressure generated in the high pressure generation circuit is held constant and the ambient temperature is changed to generate ozone from the above ozone generator, the amount of ozone ordered will decrease as the temperature increases. Are known. However, with conventional ozone deodorization equipment, the frequency of the high voltage generated by the high-pressure generation circuit is always kept constant to generate ozone regardless of the temperature of the atmosphere, so it is not possible to fully demonstrate the deodorization effect at low temperatures. However, in seasons such as summer when the generation of bad odors becomes severe under high temperature conditions, the amount of ozone generated decreases, and there is a drawback that complete removal of bad odors cannot be achieved under high temperature conditions.

The present invention overcomes the above-mentioned drawbacks of conventional ozone deodorization devices, generates a constant amount of ozone regardless of the ambient temperature, and is particularly useful in the summer when humidity and temperature rise are significant. An object of the present invention is to provide a deodorizing device that contributes to eliminating residual bad odors in toilets, etc.

The person who protects the country from 5 people! In order to solve the above problems, the toilet bowl deodorizing device using ozone according to the first stage of the present invention has an atmospheric humidity or temperature detection means of the deodorizing device and a control circuit, and the atmospheric humidity or temperature detected by the detection means is Input temperature information to the above control circuit,
The frequency is set by the control circuit so that the amount of ozone generated by the ozone generator is always constant even when humidity and temperature change, and the high voltage generated by the high voltage generation circuit is controlled by the temperature. It is characterized in that it is controlled to change accordingly.

Since the toilet bowl deodorizing device of the present invention is configured as described above, when the atmospheric humidity or temperature changes, the control circuit into which the detected temperature signal is input controls the output of the high pressure generation circuit. By changing the frequency or pulse duty ratio of the high voltage, a constant amount of ozone is always generated from the ozone generator, and a sufficient deodorizing effect can be achieved regardless of humidity or temperature.

Humidity and/or outside temperature sensor 1 detects outside temperature, and its detection signal is input to control circuit section 2 .

The control circuit 2 adjusts the frequency or pulse duty ratio of the high voltage generated by the high voltage generation circuit based on the humidity and/or outside temperature detection signal so that the amount of ozone generated from the ozone generator 5 is always adjusted even if the humidity or outside temperature changes. control so that it remains constant. The high voltage generation circuit amplifies the pulse signal from the control circuit section and converts it into a high voltage. The ozone generator 5, the catalyst 6, and the fan 9 are housed in the wind tunnel 4, and the fan 9 sucks malodorous air from an intake lower provided at one end of the wind tunnel, and the ozone generator 5 generates ozone. The mixture enters the catalyst 6, and under the action of the catalyst 6, the reaction between the malodorous components and ozone is promoted, and the deodorized clean air is discharged into the room through the exhaust port 8 provided at the other end of the wind tunnel. (e.g. in the toilet).

When the deodorizing device of the present invention is used as a deodorizing device for a toilet, a mounting member is attached to the valve seat 12 or the lid of the toilet bowl 11 at a place where the air inside the toilet bowl, which is the source of bad odors, can be directly sucked, for example, as shown in FIG. 13 is preferably provided so that the air in the toilet bowl 11 can be easily sucked into the air intake lower of the deodorizing device 10.

The control circuit 2 changes the frequency or pulse duty ratio by taking advantage of the characteristic that the amount of ozone generated increases in proportion to the number of pulsed high voltage applications.

As shown in FIG. 4, the frequency change method increases the frequency as the humidity and/or temperature increases, thereby increasing the frequency of pulsed high voltage application and increasing the amount of ozone generated. As shown in Figure 5, the pulse duty ratio changing method reduces the amount of ozone generated by applying a high voltage sparsely when the temperature is low and low humidity, and reduces the amount of ozone generated by applying a high voltage densely when the temperature and humidity is high. Increase quantity.
