Abstract

PURPOSE:To prevent sewage and flushed water within a bowl from sucking from a sucking opening, by cutting off the front upper edge of a deodorizing duct to open the suction opening at the upper part as well. CONSTITUTION:A deodorizing duct 7 is cut off at the front upper edge to be of nearly-letter shape plane-viewed to form a cut off part 9a at the front upper edge and to open the suction opening 9 to not only the front but also to the upper side. By opening the suction inlet 9 to the upper side as well, the suction force through the suction inlet 9 of an ozone deodorizing device M is weakened, even when the drain opening of the bowl is choked by any chance and the bowl is filled with water, suction of the water in the bowl and flushed water is prevented from leaking from the suction opening 9. And since the sewage and flushed water is prevented from leaking into the ozone deodorizing device M, the increase of humidity in the deodorizing device M can be prevented and generating capacity of ozone can be normally kept. And hence, an appropriate concentration of ozone can be obtain to securely deodor.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a deodorizing duct structure for a toilet bowl equipped with an ozone deodorizing device that prevents suction of sewage.

(b) Conventional technology It has been known that ozone has the ability to eliminate odors by oxidizing and decomposing malodorous components through its oxidizing action. BACKGROUND ART Toilet bowls equipped with ozone deodorizing devices have been developed to remove bad odors, for example, bad odors generated during stool or urine.

One embodiment of such a toilet with an ozone deodorizing device is that an ozone deodorizing device is provided at the rear of the toilet bowl body, and a deodorizing duct is extended from the deodorizing device toward the upper opening of the ball part of the toilet bowl body [7, same The suction port opened at the tip of the demolition duct is located near the top surface of the ball part, and the bad odor inside the ball part is inhaled through the suction port by an intake fan, while high voltage is applied to the ozone generator installed in the ozone deodorizing device. Some devices are designed to generate ozone and remove bad odors using the ozone.

(c) Problems to be Solved by the Invention However, in the above-mentioned toilet bowl with an ozone deodorizing device, since the inlet of the deodorizing duct is located near the top surface of the ball part, the drain port of the ball part may become clogged for some reason. When the inside of the ball is filled with sewage or cleaning water (washing water when flushing the toilet bowl or cleaning water when washing and draining filth), the water surface becomes close to the inlet of the deodorizing duct and a bad odor passes through the inlet. Due to the suction power of the ozone deodorizing device, the suction power of the ozone deodorizing device also sucks in the waste water inside the ball part, increasing the humidity inside the ozone deodorizing device. There is a problem that reliable deodorization cannot be performed.

Furthermore, there is a risk that a high voltage generator that applies high voltage to the ozone generator may cause an electrical leakage accident.

(d) Means for Solving the Problems Therefore, in the present invention, the deodorizing duct is extended from the ozone deodorizing device toward the upper opening of the ball part of the toilet main body, and the inlet opening at the tip of the deodorizing duct is connected to the ball. In a toilet bowl equipped with an ozone deodorizing device, which is located near the top of the bowl and is capable of deodorizing the odor inside the bowl that is inhaled through the suction port, the upper part of the tip of the deodorizing duct is cut out to open the suction port upward as well. It is an object of the present invention to provide a deodorizing duct structure for a toilet bowl with an ozone deodorizing device, which is characterized by the following characteristics.

Another feature is that the upper end of the deodorizing duct is cut out in a substantially rectangular shape when viewed from above to form a notch in the upper end of the deodorizing duct so that the suction port is opened upward as well.

(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 portion is sucked into the ozone deodorizing device through the inlet of the deodorizing duct, and the bad odor is brought into contact with ozone by the deodorizing device to decompose and deodorize the bad odor.

At this time, by notching the upper side of the tip of the deodorizing duct and opening the inlet upward, the odor suction force through the inlet of the ozone deodorizing device is weakened, so in the unlikely event that the ball part is drained. Even if the mouth is clogged and the bowl is filled with sewage or wash water, it is possible to prevent the sewage or wash water from being sucked into the ball through the suction port.

In this way, it is possible to prevent sewage and washing water from entering the ozone deodorizing device, which prevents the humidity inside the deodorizing device from increasing and maintains the ozone generation ability at its normal level. and ensure the generation of ozone at an appropriate concentration.
It is possible to provide comfortable toilet use through reliable deodorization.

In addition, it is possible to prevent electric leakage accidents in the high voltage generator, thereby improving the safety of the ozone deodorizing device.
