Espressor for thermostats of automotive air conditioners.

摘要

The present invention relates to an aspirator for an automatic thermostat of an automotive air conditioning apparatus which generates a suction force (negative pressure) capable of introducing indoor air so as to be able to detect a room temperature of the automobile.;For this purpose, the inventor of the automotive air conditioner (10) configured to allow indoor air to flow through the suction hole of the indoor temperature sensor to measure the indoor air temperature,;The esperator 20 is formed above the fan case 13 of the air conditioner 10 so that indoor and outdoor air introduced through the orifice 21 sucks air on the escalator 20 The suction hole of the temperature sensor is guided to a negative pressure state so that the room air can be introduced to measure the temperature of the room air;;The analyzer (20) comprises:;A duct groove (23) is formed on the upper surface of the fan case (13) where the orifice (21) is formed to engage the escalator duct (22).;The duct groove 23 is formed in such a manner that the negative pressure passage 25 is formed by tightly coupling the fitting protrusion 24 formed integrally with the end of the aspirator duct 22.
