A part of the ventilation passage of the outside heat exchanger is connected in communication with the toilet bowl and the toilet room, and a damper device is arranged in the connection part, and the damper device is connected to a) a fan for the outside heat exchanger installed at the rear of the toilet bowl. A first hole 13a that communicates and connects the room and the toilet bowl, b) a second hole that communicates and connects the outdoor heat exchanger fan room and the toilet room, and c) the two first and second holes that open and close at the same time. d) attached to the first damper, a second damper of the first damper;
a second damper that opens and closes the third hole by opening a third hole in the portion that closes the hole; e) an outdoor air discharge duct that connects the outdoor heat exchanger fan and the outdoors; f)
A micro switch is built into the toilet seat and is activated by the body weight while the toilet is in use to operate and stop the fan for the outdoor heat exchanger and to open and close the first damper; g) the second damper and the outdoor heat exchanger; This relates to a ventilation mechanism for a toilet air conditioner, which consists of a dexterity fan and a timer that intermittently opens, closes, and stops the fan.

(E) Functions and Effects With the above configuration, the present invention has the following functions and effects.

In the present invention, a deodorizing device is incorporated into a toilet air conditioner that can cool and heat the entire toilet room.

Therefore, a fan for the outdoor heat exchanger of a toilet air conditioner that can perform not only heating but also cooling can also be used as a deodorizing fan, reducing the overall purchase cost of the toilet air conditioner and deodorizing device that can perform cooling and heating. And installation costs can be kept low.

Since the deodorizing device is built into the toilet air conditioner that can cool and heat the entire toilet room, the narrow space inside the toilet room can be used effectively.

A part of the ventilation path of the outdoor heat exchanger is connected to the toilet bowl and the toilet room, a damper device is installed in the connection part, and by the switching operation of the damper device,
While the toilet is in use, the odor inside the toilet and the air in the toilet room are sucked out while either cooling or heating the toilet. After using the toilet, the air inside the toilet is also being cooled or heated while Since the toilet is configured so that only the air can be sucked in, it is possible to efficiently deodorize the entire toilet room while maintaining a comfortable temperature in the toilet room throughout the year, and it is also possible to save energy.

The damper device is composed of a first damper and a second damper, and the first damper and the outdoor heat exchanger fan are operated via a micro switch that is activated by the sitting motion of the human body, and the first damper is activated by a timer. 2 dampers can be driven intermittently. Therefore, by operating the first damper and the outdoor heat exchanger fan, the odor during use is forcibly discharged outside from the outdoor air discharge duct through the first hole, and the air in the toilet room is also discharged at the same time. The toilet room is ventilated by forcibly releasing air from the outdoor air discharge duct through two holes, and after use, the second damper is opened and closed using a timer to intermittently ventilate the toilet room. This is a toilet air conditioner that can.

In this way, the cooperation between the microswitch and the timer makes it possible to automatically and reliably deodorize the interior of the toilet room while maintaining it at a comfortable temperature during the entire process from the start to the end of the toilet.

Furthermore, after use, the toilet room can be ventilated intermittently, resulting in energy savings.
