Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device for blowing warm air into a toilet bowl to evacuate the anus that has been washed with cleansing water after defecating, and for deodorizing and exhausting odors inside the toilet bowl.

[Background technology]

BACKGROUND ART It has been known for some time that an anal cleaning nozzle is attached to a toilet bowl. In this case, a warm air blowing device is attached to the toilet bowl in order to blow out warm air to dry the anus after cleaning with the anal cleaning nozzle. On the other hand, there is also known a deodorizing device that deodorizes and exhausts the odor inside the toilet bowl. In the past, the warm air outlet device and the deodorizing device were separate devices, and each was individually attached to the toilet bowl. For this reason, a fan and the like are required separately, resulting in a problem of increased costs.

[Purpose of the invention]

The present invention was invented in view of the above points, and its purpose is to combine a fan or the like that integrates a hot air blowing device and a deodorizing device, and also to make it possible to switch between hot air blowing and deodorizing. Turn on the heater,
To provide a device for supplying warm air to a toilet bowl and deodorizing it, which can be turned off simply by turning it off.

[Disclosure of the invention]

The hot air supply and deodorizing device of the present invention is provided with an odor inlet 3 that opens into the toilet bowl at one end of an odor passage 2 in which a deodorizer 1 is disposed midway, and the other end of the odor passage 2 is connected to an end of an intermediate passage 4. A fan 7 and a heater 8 are arranged in the middle of the intermediate passage 4, and the end of the intermediate passage 4 opposite to the air intake opening 5 is connected to the toilet bowl. One end of the exhaust passage 10 is communicated with the vicinity of the hot air outlet 9 of the intermediate passage 4 to form a second hot air outlet.
The communication port 11 is the other end of the exhaust passage 10, and the odor exhaust port 12 is the other end of the exhaust passage 10.
and a second damper 14 for selectively closing either the second communication port 11 or the hot air outlet 9, When the second damper 14 closes the second communication port 11, the first damper 13 closes the first communication port 6, and when the second damper 14 closes the hot air outlet 19, the first damper 13 closes the first communication port 6. The second damper 14 and the first damper 13 are interlocked by the interlocking means 15 so as to close the air intake port 5, and when the temperature reaches a predetermined temperature or higher, the second damper 14 closes the second communication port 1 and blows hot air. Shape memory alloy damper operating means 16 for opening the outlet
is arranged between the heater 8 of the intermediate passage 4 and the hot air outlet 9, and with this configuration, the above-mentioned object of the present invention is achieved.

The present invention will be explained in detail below with reference to Examples. In the figure, reference numeral 2 denotes an odor passage in which a deodorizer 1 is arranged, and one end of this odor passage 2 is provided with an odor inlet 3 that opens into the toilet bowl, and the other end of the odor passage 2 is used to suck air from the end of an intermediate passage 4. A first communication port 6 is provided in communication with the vicinity of the port 5 . A fan 7 and a heater 8 are arranged in the middle of the intermediate passage 4, and the end of the intermediate passage 4 opposite to the air intake port 5 is opened into the toilet bowl to serve as a hot air outlet 9. One end of the exhaust passage 10 is connected to the vicinity of the hot air outlet 9 of the intermediate passage 4 to serve as a second communication opening 11, and the other end of the exhaust passage 10 is provided as an odor outlet 12. In the figure, 13 is a first damper for selectively closing either the first communication port 6 or the air intake port 5, and 14 is a first damper for selectively closing either the second communication port 11 or the hot air outlet 9. A second damper 14 for selectively closing one side, and when the second damper 14 closes the second communication port 11, the first damper 13 closes the first communication port 6, and the second damper 14 closes the first communication port 6. The second damper 14 and the first damper 13 are arranged so that when the hot air outlet 9 is closed at 14, the first damper 13 closes the air intake port 5.
are interlocked by interlocking means 15. The interlocking means 15 has a second arm 18 protruding from the shaft 17 of the second damper 14, a first arm 20 protruding from the shaft 19 of the second damper 13, and the first arm 20 and the second arm 18 are connected to each other. are pivotally connected by a link 21. In the figure, 16 is a damper operation means for closing the second communication port 11 with the second damper 14 and opening the hot air outlet 9 when the temperature exceeds a predetermined temperature, and the damper operation means 16 is made of a shape memory alloy. The damper operating means 16, which is a coil spring made of a shape memory alloy, is connected to the intermediate passage 4.
It is disposed between the heater 8 and the hot air outlet 9, and one end is attached to the wall of the intermediate passage 4, and the other end is attached to the second damper 14. 2 in the diagram
2 is a bias spring, one end of which is attached to an external fixed base 23, and the other end of which is attached to the second damper 1.
It is attached to a connecting arm 24 protruding from the shaft 17 of No. 4. When a person sits on the toilet seat (not shown), the deodorizing switch (not shown) is activated and the fan 7 shown in Figure 1 is activated.
rotates, sucks in the bad odor inside the toilet bowl through the odor inlet 3, and discharges it from the odor outlet 12. In this case, the heater 8 is turned off. On the other hand, when defecation is finished and the switch of the heater 8 (not shown) is turned on, the damper operation means 16 made of a shape memory alloy coil spring is warmed by the hot air, and when it reaches the transformation point, it is stretched by the bias spring 22. The damper operating means 16 made of a shape memory alloy coil spring returns to its original state.
shrinks to close the second communication port 11 and open the hot air outlet 9 as shown in FIG.
As a result, the first damper 13 also closes the first communication port 6 and opens the air intake port 5. As a result, the air sucked from the air intake port 5 is heated by the heater 8. The heated air is then blown out as warm air from the hot air outlet 9. After drying, turn on heater 8.
When it is turned off, the damper operation means 16, which is a coil spring made of a shape memory alloy, cools down and is stretched out against the tensile force of the bias spring 22, returning to the state shown in FIG. 1, and deodorization begins again. When the person leaves the toilet seat, the deodorizing switch is turned off and the fan 7 is stopped.

〔Effect of the invention〕

In the present invention, since it is constructed as described above, 1
Two fans can blow hot air and deodorize exhaust air, and even though one fan can blow hot air and deodorize exhaust gas, Switching can be done automatically by simply turning the heater on and off.
