Abstract

PURPOSE:To prevent the offensive smell of an evaporator by a simple structure wherein a damper composed of deodorizing filter is arranged at the outlet of the evaporator and the opening of the damper is delayed for the fixed periof of time at the start of the operation of the air conditioning equipment. CONSTITUTION:When a cooling switch 7 is closed, a contact 6b is kept open for the fixed period of time by means of a timing circuit 6a in order to suppress the operation of a solenoid valve 5. Consequently, no negative pressure is led into a negative pressure motor 4, resulting in keeping a damper 3 at the position A. Accordingly, because cold air passes through the damper 3 equipped with the deodorizing filter, smell is removed with the deodorizing action of the damper 3. After the elapse of the fixed period of time, the contact 6b is closed and the solenoid valve 5 is brought into operation in order to lead negative pressure into the negative pressure motor 4, resulting in opening the damper 3 to the position B in order to perform the cooling in steady state. In such a manner as mentioned above, the offensive smell of the evaporator 2 can be prevented.

In FIGS. 1 and 2, 1 is a case, and the case 1 houses an evaporator 2 for cooling and a plate-shaped breathable damper 3. This damper 3 is composed of a deodorizing filter. The deodorizing filter has a structure in which a case is filled with granular activated carbon so that it does not move, or a structure in which reinforcing nonwoven fabric is bonded to both sides of activated carbon fibers.

It has become. 5 is a solenoid valve that turns on and off communication between the negative pressure source and the negative pressure motor 4. Reference numeral 6 denotes a delay device, which consists of a time limit circuit section 6a and its contact 6b, and when the time determined by the time limit circuit 6a has elapsed, the contact 6b
is closed, and the solenoid valve 5 is energized. When this electromagnetic valve 5 is energized, negative pressure is introduced into the negative pressure motor 4. 7 is a cooling switch, and when this switch 7 is closed, the cooling compressor (
(not shown) is energized, and the delay device 6 is energized.

Since contact 6b does not close for a certain period of time due to a, solenoid valve 5
is not energized, and no negative pressure is introduced into the negative pressure motor 4.

従って、ダンパ３は第２図のへのごとくエバポレータ２
の出口側を閉じたままであるため、エバ（３） ボレータ２を通過した冷風はダンパ３を通過する。Therefore, the damper 3 is connected to the evaporator 2 as shown in FIG.
Since the outlet side of the evaporator (3) remains closed, the cold air that has passed through the volator 2 passes through the damper 3.
