Abstract

The present invention relates to a device for deodorizing bad odor generated by the use of a toilet. The device is particularly intended for tank-tight toilets. The difference between the present invention and the conventional one is that it can be applied to an existing toilet and a new toilet. This device is also characterized in that it deodorizes from the existing outlet of the toilet.

Description

  The present invention relates to a device for deodorizing bad odor generated by use of a toilet. The device is particularly intended for tank-tight toilets. The difference between the present invention and the conventional one is that it can be applied to an existing toilet and a new toilet. This device is also characterized in that it deodorizes from the existing outlet of the toilet.

  Patent US 5,839,127 also deodorizes from the toilet outlet, but the intake performance is relatively low because the intake uses a narrow path originally designed to drain excess water from the tank. Another disadvantage is that it is somewhat difficult to improve the existing toilet because it requires interference with the parts in the tank.

  According to the surveys conducted, other patents deodorize after the internal odor is discharged from the toilet bowl, but the odor has already leaked into the environment and is outside the scope of the present invention. Other attempted solutions are outside the scope of the present invention because they are masked with a fragrance rather than deodorized.

US Pat. No. 5,839,127

-Can be installed in a new toilet and sold as a retrofit kit (accessory) for an existing toilet.
・ Never interfere with either tank or toilet. On the other hand, it is a product installed between the tank and the toilet. The advantages of this configuration are easy to understand for both the practitioner and the householder, and do not require specialized effort, so that the product is ultimately easy to spread and accept.
・ Production and implementation costs can be reduced.
・ A valve is not necessary to separate air and water using gravity. The valve requires a sealing material, which is expensive and may be defective.

The subject represents one of the implementation methods in the attached figures. It is possible to introduce other configurations that replace the parts that play the same role while maintaining the basic characteristics. The attached figure represents the following:
It is the whole figure installed. It is a front view of a junction and a tank. It is a top view of a junction part. It is sectional drawing of a siphon.

  This device basically consists of the above-described exhaust system that is activated in the presence of a user, and the joint (1) between the tank (2) and the toilet. The exhaust port is connected to the existing drainage structure. Attached.

  The above joint (1) is hollow inside, and in addition to the water supply port (5) and drainage port, the inner tank (4) with the ventilation port (6) and the exhaust port (7) (exhaust to the outside) Consists of. Two exhaust ports (7) can be assumed, but one side on both sides of the coupling part (1) can be selected as the side where the ventilation device is installed. In this case, the unused one is sealed with a cap (8). Ventilation is forcibly performed mechanically by a fan (9) installed downstream of the exhaust pipe and connected to the main power supply by a power cable (10). One end of the fan communicates with the inner tank (4) through the duct (11), and the other end communicates with the duct (12) that exhausts to the outside. The fan (9) is set at a position above the maximum water level of the inner tank (4), but ideally, it is necessary to ensure that the drainage does not reach at a position above the top of the tank. If it is desirable to install the fan at the same water level or below the tank bottom for reasons such as appearance or securing space, the present invention assumes a siphon (inverted U shape) (16). This forces the fan intake to exceed the water level. When the fan is incorporated in the joint, the duct outlet (12) is movable, so that it is easy to install.

  Even if the inner tank (4) and the exhaust duct (11) are full at the time of discharge and the collection of odors is stopped, the lower inner surface (13) of the inner tank (4) is inclined toward the center. Water can flow into the toilet and odor recovery can be resumed.

  The joint (1) communicates with the upper tank (2) and the lower toilet (3), which is similar to a genuine seal ring that tightly connects the toilet to the tank. 14) is used. The joint (1) has an outer shape that matches the shape of the toilet bowl and the tank, so that the weight of the tank is applied to the toilet bowl and the design is harmonized. The fan can be activated by a switch and can also incorporate a human sensor (15) that detects the user's entry. The human sensor can also have a timer function that activates the fan for a certain period of time after using the toilet to ensure complete exhaust.

  When retrofitting equipment to an existing toilet in a building, it is only necessary to remove the tank (2) from the toilet (3) and align the joint (1) between them. In the case of a new toilet, the joint portion can be manufactured by being incorporated in a tank at a factory, and is installed on the toilet as a unit like a conventional tank.

  The numbers in the drawing represent the following parts:

DESCRIPTION OF SYMBOLS 1 Junction part 2 Water tank for discharge 3 Toilet bowl 4 Inner tank 5 Water supply port of inner tank 6 Drain outlet and ventilation port of inner tank 7 Exhaust outlet of inner tank 8 Cap 9 Fan 10 Power cable 11 Ventilation from inner tank to fan Duct 12 Fan duct outlet 13 Lower inner surface of inner tank 14 Seal ring 15 Human sensor 16 Siphon

Claims (3)

  The toilet deodorizing device is characterized in that it is located between the tank (2) and the toilet (3) and has a joint (1) communicating with both. The joint (1) is composed of an inner tank (4) with a hollow inside and an inclined inner surface (13) at the bottom, and a water supply port (5), a drain port, a ventilation port (6) and an exhaust. Has a mouth (7). Ventilation is performed mechanically by a fan (9) installed downstream of the exhaust pipe and connected to the main power supply by a power cable (10). The fan communicates with the inner tank (4) through the duct (11) and is positioned above these maximum water levels.   The toilet deodorizing apparatus according to claim 1 is characterized in that, in terms of structure, the joint (1) is incorporated in the tank (2) and the integrated part communicates with the toilet (3).   When the fan (9) is desired to be installed at a position within the maximum water level of the inner tank (4) in terms of structure, a siphon (16) is assumed between the inner tank and the fan. It has the characteristics where it is done.
