[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention effectively utilizes the connection pipe and the ventilation fan that connect the existing flush toilet and the water tank, and efficiently removes the odor in the flush toilet without damaging the appearance of the connection pipe and the surroundings and the drainage efficiency. The present invention relates to a deodorizing device for a toilet that can surely deodorize.

[0002]

[Prior art]

 In general, toilets are provided with ventilation fans on the walls and ceiling, but this is for ventilating the entire air inside the toilet, so it is not possible to effectively deodorize the odor inside the flush toilet. . It may be possible to connect the ventilation fan via a pipe to the connecting pipe that connects the flush toilet and the water tank so that the odor in the flush toilet can be directly sucked by the ventilation fan. If only the pipes are connected, not only the appearance of the connecting pipes and the surroundings will be damaged, but also the drainage efficiency of the water tank will be impaired due to the suction by the ventilation fan during washing with water. Therefore, in the past, there was nothing that could efficiently and surely deodorize the odor in the flush toilet except by attaching an expensive and special device such as an ozone deodorizer to the flush toilet.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of such an actual situation, and it is not necessary to provide an expensive device such as an ozone deodorizing device, and a connecting pipe for connecting an existing flush toilet and a water tank and a ventilation fan are effective with a simple structure. The purpose of the present invention is to provide a deodorizing device for a toilet that can efficiently and reliably deodorize odors in flush toilets without damaging the drainage efficiency of the connection pipe, the appearance of the surrounding area and the water tank. To do.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms a part of a connecting pipe connecting a flush toilet and a water tank as a large-diameter pipe part, and the inside of this large-diameter pipe part is provided with a vertical partition wall of a considerable length. It is divided into a drain pipe part and a ventilation port that are connected in the space below the side tip part, and the drain pipe part is closed at the lower end part of the vertical partition wall when not using water washing and the ventilation port when using water washing. It is characterized in that a hook-shaped rotary valve body that closes the part is pivotally attached, and the ventilation port part and the ventilation fan are connected by a thin pipe. The operation of such a rotary valve element is performed via a pulling or pressing spring or the like.

Further, in order to achieve the above-mentioned object, more specifically, a part of the connecting pipe connecting the flush toilet and the water tank is formed as a large-diameter pipe part, and the inside of the large-diameter pipe part is vertically partitioned by a considerable length. It is divided into a drainage pipe part and a ventilation port part which are connected to each other in a space below the lower end of the vertical partition wall, and the valve body is bent into a hook shape at the lower end of the vertical partition wall. A hook-shaped rotary valve body with a weight attached to the part located on the ventilation port side is used to pivotally attach the bending center part to the axis, and the suction port that covers about half of the ventilation port and the outer surface of the ventilation fan. It is characterized in that the mouth and the pipe are connected by a thin tube.

[0006]

[Action]

 When not using the flush, the hook-shaped rotary valve body pivotally attached to the lower side of the vertical partition wall that divides the large-diameter pipe section of the connection pipe between the water tank and the flush toilet is operated by the gravity action of springs and weights. The drain pipe part is closed by rotating to the drain pipe part side, and the ventilation port part is opened, and the odor in the flush toilet is directly sucked through the connecting pipe, the ventilation port part and the narrow tube by the ventilation fan. When the water is used for washing, in which the water in the water tank is made to flow down to the connecting pipe by rotating the rotary lever of the water tank, the pressure of the water flowing down causes the rotary valve element to rotate toward the ventilation port side, blocking the ventilation port. Since the drainage pipe is opened, there is no inconvenience that part of the water flowing down in the drainage pipe is sucked by the ventilation fan to form water droplets and rises on the ventilation port side. It is sent in the toilet bowl. When the water supply for flushing is stopped, the rotary valve body returns to its original position, and the odor in the flush toilet is sucked again by the ventilation fan.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the attached drawings. Reference numeral 1 is a connecting pipe that connects a water tank 2 and a flush toilet (not shown). The root portion of the water tank 1 side is swollen on the back side to form a large-diameter pipe portion 3. This large-diameter pipe portion The interior of 3 is vertically divided into two parts with a vertical partition wall 4, and is divided into a drain pipe part 5 on the front side and a ventilation port part 6 on the rear side. The drain pipe part 5 and the ventilation port part 6 are connected to each other in the space below the lower end of the vertical partition wall 4. A rotary valve body 7 that bends in a hook shape is pivotally attached to the lower end of the vertical partition wall 4 with its bending center as an axis, and the ventilation port portion 6 side of the valve body that bends in a hook shape is located. A weight 8 is attached to the tip of the portion located at. Therefore, in a normal state (when the water is not used for washing) in which water does not flow out from the water tank 2, the rotary valve body 7 rotates clockwise about the axis as shown in FIG. 5 is closed and the ventilation opening 6 is opened. On the other hand, when the water is washed from the water tank 2, the rotary valve body 7 is pushed by the pressure of the water flowing out against the gravity action of the weight 8 and rotates in the counterclockwise direction as shown in FIG. The portion 6 is closed and the drain pipe portion 5 is opened. When the water supply from the water tank 2 is stopped, the rotary valve body 7 returns to the original position in FIG. 1 due to the gravity effect of the weight 8. A connection hole 9 is provided on the side surface of the ventilation port portion 6, and the connection hole 9 is pipe-connected through a thin tube 12 to a suction port 11 that is attached to the wall surface while covering the outer surface of the ventilation fan 10. . The suction port 11 does not cover the entire outer surface of the ventilation fan 10 but covers about half thereof. The thin tube 12 is made of a flexible material and is piped using the corner portions of the wall surface, the wall surface, the floor surface, and the ceiling surface, and is attached inconspicuously from the outside. The ventilation port 6 is closed on the outer surface except for the connection portion with the drainage pipe portion 5 inside and the connection hole 9 for connecting the thin tube 12 inside. In the figure, 13 is a rotary lever for water supply provided in the water tank 2.

In the above-mentioned embodiment, the drainage pipe portion 5 is opened during the water washing and the ventilation port portion 6 is closed by utilizing the gravity action of the weight 8 and the rotation of the rotary valve body 7 due to the water pressure. Although the drain pipe is shown as having the closed ventilation port 6 opened, the drain pipe is not limited to this, and the elastic force of the spring and the pressure of water may be used. Moreover, although the suction port 11 that covers about half of the outer surface of the ventilation fan 10 is shown, the invention is not limited to this, and the thin tube 12 may be connected to the ventilation fan 10 by other suitable means.

[0009]

[Effect of device]

 Since the present invention has the above-mentioned configuration, it solves the above-mentioned problems of the conventional technique and has the following effects.

In claim 1, a. The ventilation port 6 for sucking the odor in the flush toilet is provided with a part of the connecting pipe 1 connecting the water tank and the flush toilet as a large-diameter pipe portion 3 and the water is inserted through a vertical partition wall 4 inside the connection pipe 1. Since it is separated from the drainage pipe 5 for washing, it is seen from the outside as an integral part of the connecting pipe, and the large diameter pipe 3 is provided on the back side of the connecting pipe 1 so that a bulge is provided. Since the large-diameter pipe section 3 is not visible from the front side by forming it, the appearance of the connecting pipe 1 and its surroundings is better than when connecting another pipe for ventilation to the connecting pipe 1. There is no loss of appearance. Further, since the ventilation port section 6 and the ventilation fan 10 are connected to each other by the thin pipe 12, the connected state of the pipe is not conspicuous, and this does not impair the appearance of the inside of the toilet. b. Due to the rotation of the hook-shaped rotary valve element 7 pivotally attached to the lower end of the vertical partition wall 4 that divides the large-diameter pipe part 3, the drain pipe part 5 opens and the ventilation port part 6 closes when washing with water. Since the opposite is true when washing with water, the water transfer efficiency for washing is not impaired by the suction action through the ventilation port 6 and is not impaired, and water drops are sucked up through the ventilation port 6. In addition, since the drain pipe 5 is closed during non-washing, excess air in the connecting pipe 1 is not sucked in through the ventilation port 6, so that the flush toilet 10 uses the flush fan 10. The odor inside can be sucked efficiently and reliably. c. The overall structure of the device is extremely simple, and it is possible to economically deodorize odors in the flush toilet bowl.

In claim 2, d. It has the same effect as a, b, and c in claim 1. e. Furthermore, since the rotation of the rotary valve body 7 is performed by utilizing the gravitational action of the weight attached to a part of the valve body, the structure of the valve body is simpler and economical compared to the case where a spring or the like is used. In addition, it is suitable for use because there is no risk of failure. f. Since the ventilation fan and the ventilation opening 6 are pipe-connected by using the suction port 11 that covers almost half of the outer surface of the ventilation fan 10, the odor in the flush toilet bowl that has been sucked may be diffused or leaked into the toilet. The deodorizing effect is further perfected and there is no risk of obstructing ventilation in the toilet. In addition, the labor of piping connection between the ventilation fan 10 and the ventilation port section 6 is simplified.
