Abstract

PURPOSE:To always keep the humidity below than a preset figure, generating a sufficient volume of ozone, and realize a secure deodorizing effect, by providing an ozonizer generating ozone, a humidity sensor, and a heater actuating when the humidity is higher than a preset humidity, in an ozone generator. CONSTITUTION:An ozonizer 17 is jointed to a high tension voltage generator 19 and the high tension voltage is charged from the high tension voltage generator 19 to the ozonizer 17 in accordance with the driving output from a controller D to generate ozone in a deodorizing duct 7. A humidity sensor 16 detects the humidity at the atmosphere of the ozonizer 17. When the detected result is higher than the preset humidity, a heater 18 is actuated according to the driving output from the controller D to lower the surrounding humidity of the ozonizer 17 than the preset humidity. And the heater 18 heats the ozonizer 17 to promote generation of ozone by the ozonizer 17. For always keeping the humidity lower than the preset figure, even just after the ozone deodorizing device M is started, a sufficient volume of ozone is generated from the ozonizer 17 and a secure deodor effect can be obtained.

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an ozone deodorizing device that can effectively eliminate bad odors using ozone (and is equipped with four humidity sensors).

(b) Conventional technology It has long been known that ozone has the ability to oxidize and decompose sodium components through its oxidizing action, eliminating odors. For example, technology has been developed to deodorize the bad odors that occur when urinating.

For example, in Japanese Patent Application Laid-Open No. 80-31719, there is a toilet i (
The ozone deodorizing device is built into the unit, and the odor is inhaled through the inlet and sucked into the device, and the ozone generator installed in the device generates ozone by electric discharge action, causing the ozone and the bad odor to come into contact. A technology has been disclosed in which the bad odor is decomposed and deodorized by the toilet body or discharged from the toilet body or an outlet opening to the outside.

(c) Problem to be invented or solved However, the amount of ozone generated in the ozone generating part installed in the ozone deodorizing device mentioned above changes significantly depending on changes in the humidity around the ozone generating part, and when the humidity is high, However, there was a problem in that a sufficient amount of ozone was not generated from the ozone generating section, and deodorization using ozone could not be performed effectively.

Therefore, as a countermeasure against high humidity, a heater has been developed in the ozone generating section that is activated in conjunction with the start of the ozone deodorizing device when the power is turned on. However, even when the heater is activated, it takes time to eliminate condensation and reduce humidity, and there is a problem in that a sufficient deodorizing effect cannot be obtained immediately after the power is turned on.

(d) Means for solving the problem Therefore, in the present invention, one end of the deodorizing channel, in which the ozone deodorizing device is disposed midway, is opened into the bowl part of the toilet bowl body to serve as an inlet, while the other end is In an ozone deodorizing device, the odor is opened inside or outside the toilet body and serves as an outlet, and the odor in the ball part (a) inhaled from the inlet is deodorized by ozone and can be discharged from the outlet. The ozone generating section is characterized by being provided with an ozonizer that generates ozone, a humidity sensor that detects the humidity around the ozonizer, and a heater that operates when the detection result by the humidity sensor is higher than a set humidity. It is an object of the present invention to provide an ozone deodorizing device equipped with a humidity sensor.

(e) Action/effect According to the present invention, the following effects are produced.

That is, in the present invention, the bad odor inside the ball is sucked into the ozone deodorizing device through the suction port which is one end of the deodorizing flow path, and the bad odor is combined with ozone generated by the discharge action of the ozone generating section provided in the ozone deodorizing device. By contacting it, it can decompose and deodorize bad odors.

At this time, if the humidity around the ozone generator is higher than the set humidity (humidity that adversely affects ozone generation by the ozone generator), the humidity sensor detects the same humidity, and based on the detection result, the heater In order to appropriately lower the humidity by operating the ozone generating section, a sufficient amount of ozone is constantly generated from the ozone generating section, thereby making it possible to carry out effective deodorizing treatment.

In this way, the humidity can be kept below the set level at all times, so even immediately after starting the ozone deodorizing device, a sufficient amount of ozone can be generated from the ozone generator to ensure a reliable deodorizing effect. be able to.

Furthermore, since the humidity sensor and the heater are linked, it is possible to reduce power consumption compared to the conventional case where the heater is constantly operated.
