Each is provided. The blower unit 6 is a blower fan 6a, and the blower fan 6a communicates with an intake port 10 provided in the upper portion of the air conditioning unit 1. By operating the blower fan 6a, the air in the toilet room 2 can be sucked from the intake port 10. A heat exchanger 8 is provided below the blower unit 6. This heat exchanger 8 is a heat pump type heat exchanger 8 and can change the blast air to cold air by allowing it to cool. Below the heat exchanger 8, a switchable damper part 9 is provided which can be switched. This switching damper section 9 is communicated with a cold air outlet 11 provided in the substantially central portion of the air conditioning unit 1, and in summer the switching damper 9a is switched to an open state to allow the blower fan 6a to cool. The cold air sent through the heat exchanger 8 can be ejected from the cold air outlet 11. A warm air outlet 3 is provided below the cold air outlet 11 and below the air conditioning unit 1.
A blast heating air passage 4 is formed inside the warm air outlet 3, and a PTC heater 5 is arranged in the blast heating air passage 4. At this time, the PTC heater 5 is fixed to the bottom plate 1a of the air conditioning unit 1 by a heat holder 17 which is fixed by a fixing member 16 such as a screw. Then, the blown air sent from the blower fan 6a is heated by the PTC heater 5 so that the warm air can be ejected from the warm air outlet 3. At this time, the blower fan 6a is designed to blow air toward the PTC heater 5 after a lapse of a certain time after the PTC heater 5 is operated by a timer or the like. With this configuration, air is not blown toward the PTC heater 5 until a certain period of time elapses, and air is not blown toward the PTC heater 5 before the certain period of time elapses. Does not require a long time to reach a steady output, and it can rise quickly to a steady output in a short time.Because the air is blown after it reaches a steady output after a certain period of time, Since warm air can be jetted to the inside of the vehicle and hot air is jetted through the PTC heater 5 after the steady output is achieved, warm warm air can be jetted from the beginning of heating. At this time, the hot air outlet 3 is the toilet seat 1 in the toilet room 2.
It is provided at a position where hot air is ejected to the feet of a person when the person is seated at 2. Since hot air can be ejected to the feet in this way, the warm air can heat the inside of the toilet room 2 from the feet that are easily cooled in winter, and even if the entire toilet room 2 is not completely heated, it is warm. You can feel it. Further, at this time, since warm air is discharged from the feet to heat the inside of the toilet room 2, the warm air will flow from the bottom, which is the feet, to the upper,
The inside of the toilet room 2 can be efficiently heated. 1
Reference numeral 3 is a filter for dust-proofing, deodorizing and aromatizing the air sucked from the intake port 10. With such a structure, when the air in the toilet room 2 is sucked from the intake port 10 immediately after the suction. Can be dust-proofed, dust and dirt can be prevented from adhering to the heat exchanger 8 and the blower fan 6a, and the deodorization and aroma of the air in the toilet room 2 can be performed at the same time. . In FIG. 2, reference numeral 14 denotes an air passage guide, which is arranged so as to be inclined upward from the upper portion of the PTC heater 5 toward the warm air outlet 3. At this time, as the air guide 14, a steel plate, an aluminum plate, a heat-resistant resin plate, a glass wool plate, a mica plate, or the like,

As shown in FIG. 3, the PT is provided when air is not being blown from the blower fan 6a toward the PTC heater 5.
The warm air warmed by the C heater 5 can be guided to the outside by natural convection as shown by the arrow A in the figure. Further, by providing the blower guide 14, it is possible to thermally shield the constituent member 15 disposed above the PTC heater 5 and prevent an adverse effect due to the heat of the PTC heater 5. Fourth
In the figure, the blower guide 14 is configured to be doubled by the upper blower guide 14a and the lower blower guide 14b, and by such a configuration, the convection of warm air guided to the outside is obstructed. Without this, the natural convection can be promoted by the chimney effect, and the hot air guided to the outside can be emitted more efficiently. Further, since the blower guides 14 are doubled, it is possible to reliably insulate the upper component member 15 of the PTC heater 5 from heat. Further, a resistance wire heater 7 whose output voltage is small during operation in the blower heating air passage 4 and which returns to the rated voltage by a resetting means such as a timer after a lapse of a fixed time is provided in the air conditioning unit 1 after the resistance wire heater 7 operates. Even when the air blower 6 that blows air into the toilet room 2 is provided via the resistance wire heater 7 after a certain time has passed, the same effect as that of the above-described embodiment can be obtained. Further, the control of the resistance wire heater may be controlled as shown in FIG. That is, after the SW ₁ is put into the preheating operation side, the SW ₁ may be switched to the normal operation side by a timer or the like after a predetermined time has elapsed to perform control. Further, SW ₂ on the normal operation side may be switched between strong and weak to control the output of the resistance wire heater 7. At this time, the operation of SW ₂ may be performed by a temperature sensor, a human body detection sensor, a relay, etc. provided in the air conditioning unit 1.
