Depending on the polarity of the DC power supply 30 in this case, one surface 19a of the thermoelectric element 19 serves as a cooling surface, the other surface 19b serves as a heat dissipation surface, and the first heat exchange fins 21 function as cooling fins.
The second heat exchange fins 23 function as heat radiation fins.

As a result, in the lower space 15, the air sucked from the suction port 25 by the operation of the first blower 27 is first removed by the deodorant.
It is deodorized by passing through the inside of 31, and is further cooled by the first heat exchange fins 21 and is discharged from the blower port 9 to the telephone 4 side as cooling wind, and this cooling wind hits the upper body of the user of the telephone 4. Along with the cooling operation, the first heat exchange fin 21
Condensation water generated on the surface is received by the drain pan 29. Then, the dew condensation water collected in the drain pan 29 is sucked up by the moisture absorbing paper 60 and evaporated in the upper space 17 from the upper portion of the moisture absorbing paper 60 into the ventilation passage.

On the other hand, in the upper space 17, the air sucked from the suction port 39 through the suction port 51 by the operation of the second blower 35 is heated by the second heat exchange fins 23, and the heated air is discharged. The air discharged from the outlet 33 is further discharged to the outside via the outlet 50.

Since the thermoelectric element 19 has a high cooling operation speed, the cooling air from the blower port 9 is obtained immediately after the start of the call, and the caller can talk comfortably. Furthermore, the sound emitted when the air conditioner 7 operates is only the blowing sound of the first and second blowers 27, 35, and there is almost no noise or vibration.

b. (When the outside air temperature is below the lower set temperature) If the outside temperature is below the lower set temperature (for example, 18 ° C) during winter, etc., the warm air mode detection signal S3 from the temperature detection circuit 14
Based on the above, in the output voltage polarity switching circuit 12, the pair of fourth movable contacts 28a, 28b are connected between the fixed contacts 24a ₁ , 24b ₂ and 24a ₂ , 2b.
4b ₁ during which a state of connecting respectively, when line connection detection signal S1 from the line connection detecting circuit 10 telephone line in this state is connected is given, 20a of fixed contacts _1, 2
0b _{1 and} 20a ₂ and 20b ₂ are respectively connected by the first and second movable contacts 22a and 22b, the thermoelectric element 19 of the air conditioner 7 is activated, and the first and second blowers 27, 35 works.

Depending on the polarity of the DC power supply 30 in this case, one surface 19a of the thermoelectric element 19 serves as a heat radiation surface, the other surface 19b serves as a cooling surface, and the first heat exchange fins 21 function as heat radiation fins.
The second heat exchange fins 23 function as cooling fins.

As a result, the warm air heated by the first heat exchange fins 21 is discharged from the blower port 9 to the telephone 4 side. in this case,
The second heat exchange fins 23 perform the cooling operation, and the condensed water is received by the drain pan 37. Then, the dew condensation water collected in the drain pan 37 is sucked into the moisture absorbing paper 60 and evaporated from the lower portion of the moisture absorbing paper 60 into the ventilation passage in the lower space 15.

c. (When the outside air temperature is between the upper and lower set temperatures) When the outside air temperature is between the upper and lower set temperatures, such as in spring and autumn, the temperature detection circuit 14 outputs both the cold air mode detection signal S2 and the warm air mode detection signal S3. In the output voltage polarity switching circuit 12, the third movable contacts 26a, 26b and the fourth movable contacts 28a, 28b do not connect the fixed contacts 24a ₁ , 24b ₁ , 24a ₂ , 24b ₂ together, and therefore this state , A telephone line is connected, a line connection detection signal S1 from the line connection detection circuit 10 is given, and the fixed contacts 20a ₁ , 20b ₁ and 20a ₂ , 20b ₂ respectively have first and second movable contacts 22a, The thermoelectric elements 19 do not operate even when they are connected by each of the first and second terminals 22b.
Blowers 27 and 35 are operated and only air is blown.

As shown in FIG. 5, the call detecting means does not detect the call state directly from the telephone 4 as described above.
This may be performed by using a detector 40 that detects various elements that are effective in determining that the telephone 4 as the call detecting means is in a call state. As the detector 40, a system provided in the telephone box 1 is not used. An infrared human body detector for detecting the human body of the user of the telephone 4, a call voice detector constructed by incorporating a microphone, and the like using a door open / close detector for detecting the opening / closing of the door of the telephone box 1 are also provided.
