Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a deodorizing structure provided in a toilet bowl.

(Conventional Deodorizing Structure) FIG. 2 is a side sectional view showing a Western-style toilet 1 having a conventional deodorizing structure. This deodorizing structure uses the feed path for the toilet bowl cleaning water provided from the low tank 2 into the toilet bowl 1a in the reverse flow direction to remove the odor that may be generated in the toilet bowl 1a. It was a suction and exhaust. That is, the feed passage, a rim water passage 1b provided in the upper edge peripheral portion of the toilet bowl 1a, a water supply chamber 1c on the rear side of the toilet bowl for supplying toilet bowl cleaning water to the rim water passage 1b, It was formed in series by the valve seat 3 which sends the water stored in the raw tank 2 to the water supply chamber 1c. And in the low tank 2, the valve seat 3
The open end 3b of the overflow pipe 3a that is diverged from the
The intake device 4 was housed so as to face. Therefore, the odor generated in the toilet bowl 1a is to be exhausted to the outside of the toilet room from the intake device 4 in the low tank 2 by going up in the reverse flow direction in the feed path.

(Problems to be Solved by the Invention) The conventional deodorizing device is controlled to start or stop by a switching operation of a human body detecting device (not shown) attached to the toilet 1. That is, the human body detecting device is one in which an infrared sensor or the like is attached to the peripheral portion of the toilet seat 5, and the infrared sensor is
The intake device 4 is electrically connected only while a person is sitting on the toilet seat 5. Therefore,
The conventional deodorizing device does not operate when it is used by a boy (when he is not sitting on the toilet seat 5), and is not functionally satisfactory. However, in order to solve this, an infrared sensor is additionally arranged also on the front side of the toilet 1, or an infrared sensor arranged around the toilet seat 5 has a high sensitivity (a long detection distance).
However, this not only raises the manufacturing cost of the human body detection device, but also causes a malfunction of the intake device 4 due to mutual interference of the sensors. In addition, if the intake device 4 is connected in parallel to the electric power line of the toilet room, when the user enters the toilet room, the deodorizing function can be activated, but the wiring Since the construction is troublesome and, of course, it cannot be done by an amateur, it must be said that it had difficulty in installation.

The present invention has been made in view of the above circumstances, and is a novel toilet bowl which is structurally extremely simple and functionally sufficiently satisfactory. The purpose is to provide a deodorizing structure (hereinafter referred to as the main structure).

"Constitution of device" (Means for solving the problem) The main point of the structure of the present invention is to send the toilet bowl cleaning water between the inside of the low tank installed inside the toilet bowl on the upper side of the toilet bowl and the inside of the toilet bowl. An odorous upstream passage using a supply passage is provided, and an intake device communicating with the upstream passage is provided in the low tank, and the float portion is positioned so as to be able to move up and down in a predetermined water level region of the stored water in the tank. The starting switch for the intake device is provided.

(Operation) The start switch for the intake device is the float part that comes down as soon as the water level in the low tank drops.
Since it is in the ON state, regardless of the purpose of use of the toilet bowl, the deodorizing function can be obtained only by flushing the toilet bowl wash water.

(Embodiment) The present invention will be described below with reference to the drawings showing an embodiment thereof.

FIG. 1 is a front sectional view showing a raw tank 2 in which the structure of the present invention is implemented. In the proposed structure, the starter switch 6 for starting the operation of the intake device 4 is provided with a characteristic structure.

The start switch 6 is electrically connected to the intake device 4 and controls the start or stop of the intake device 4. Unlike the conventional deodorizing structure, the starting switch 6 does not have an infrared sensor or the like, but instead has a float portion 7 that moves up and down according to the change in the water level of the stored water in the tank. The float portion 7 is guided so as to slide in the vertical direction along a guide bar 6a hanging from the start switch 6. When the toilet bowl (see FIG. 2) is not in use, it floats on the water surface in a predetermined water level area where the raw tank 2 is filled with water.
Further, when the float portion 7 descends from the predetermined water level area even a little, the float portion 7 mechanically or electrically detects the presence or absence of the positional operation with respect to the guide bar 6a, and transmits it to the start switch 6. It is like this.

Although not shown in the drawings, an appropriate timer mechanism is built in the inside of the start-up switch 6, and after the transmission signal from the float unit 7 is received, the intake device is operated for several tens of seconds or several minutes. It is wired so as to maintain the energized state to No. 4.

Note that the intake device 4 is connected to the inside of the toilet bowl 1a by a run-up path that uses the feed path for the toilet bowl cleaning water in the reverse flow direction, as in the conventional deodorizing structure shown in FIG. It is scented. That is, as shown in FIG. 2, the run-up path is a rim water passage 1b provided in the upper edge peripheral portion of the toilet bowl 1a, and a rear side of the toilet bowl for supplying the toilet bowl cleaning water to the rim water passage 1b. Water supply room 1c
And a valve seat base 3 for supplying the water stored in the raw tank 2 to the water supply chamber 1c, and an overflow pipe 3a which is erected from the valve seat base 3 and stands upright. Further, in the present embodiment, as shown in FIG. 1, in the intake device 4, the lower end of the odor absorbing pipe 8 is connected to the tank by connecting the odor absorbing pipe 8 to the intake port 4a thereof. The overflow pipe 3a is covered with the stored water.
If this is done, the water level in the tank will be 8
Even if it is lower than the lower end portion of the low tank 2, it is possible to prevent the odor rising upstream in the overflow pipe 3a from being diffused into the low tank 2, so that the low tank 2 does not need to have a sealed structure. , To prevent the structure from becoming complicated.

In the structure of the present invention constructed in this manner, the intake device 4 will surely operate when the toilet bowl 1a is washed, whether in the case of men's small use or in other cases. . Therefore, the deodorizing function can be sufficiently satisfied.

(Examination of Another Mode) When the start switch 6 is configured to be able to transmit a different type of signal depending on the descending degree of the float portion 7, the energization holding time for the intake device 4 can be reduced when the boy is using the machine and when not using it. Can be different. That is, in the case of men's pursuit, the odor that can be generated is small, so that the intake device 4 is operated for a short time.
Can be used for a relatively long time. In the above-described embodiment, the intake device 4 and the start switch 6 are housed in the space behind the lid 2a of the low tank 2 in its space. However, it goes without saying that these storage locations may be on the main body side of the raw tank 2. As described above, the configuration and shape of the structure of the present invention can be appropriately changed according to the embodiment.

"Effect of the device" As is clear from the above description, the deodorizing structure of the toilet according to the present invention realizes an extremely simple structure in which the starting switch having the float portion is used as the operation starting means of the intake device. is doing. The structure of the present invention can obtain a sufficiently satisfactory deodorizing function even by adopting such a simple structure. Since the structure of the present invention can adopt the simple structure as described above, the manufacturing cost is one tenth or less of that of the conventional one using an infrared sensor or the like. It has many excellent advantages such as
