Air Conditioning Units for Vehicles

Abstract

The vehicle air conditioning unit installed in the center console of the vehicle includes an air conditioning case (12), a blower unit (26), a cooler (16) having a core part (161), and the condensed water generated in the cooler to the air conditioner. Drain port (129) for discharge outside the housing. The drain path of the condensed water from the boundary part (S) with the blower part in the bottom surface of an air-conditioning case to a drain port inclines downward as it approaches a drain port. The vehicle air conditioning unit is formed with backflow prevention ribs (126a to 126i) erected on the bottom surface of the air conditioner case so as to extend in a direction intersecting with the width direction of the air conditioner case, and direct the condensed water to the drain port. I guide, and a weapon prevents the backflow of the condensed water to the blower part side. The backflow prevention rib is formed below a line that connects from the boundary portion with the blower portion in the bottom surface of the air conditioner case to the lower end of the surface on the upstream side of the air flow of the core.

Description

[0001] Cross-references to related applications [0002] This application is based on the JP Patent application number 2016-33498 for which it applied on February 24, 2016, The description content is incorporated in this application by reference. technical field [0003] The present invention relates to a vehicle air conditioning unit installed in a center console in a vehicle interior. Background technique [0004] Conventionally, as a vehicle air-conditioning unit mounted on a vehicle, there is an air-conditioning unit included in a vehicle air-conditioning apparatus described in Patent Document 1, for example. The air-conditioning unit has a first casing with a built-in blower, a second casing with a built-in cooler, and a pipe connecting the first casing and the second casing, and the air-conditioning unit is such that the pipe runs from the first casing toward the second casing. The casing is set in a manner of gradually inclining downward. In addition, in this air co...

Problems solved by technology

Therefore, there is a problem that, when acceleration toward the front of the vehicle is applied to the condensed water, such as when the vehicle is traveling downhill, when emergency braking is performed, or when the vehicle is making a sharp turn, the condensation accumulated on the bottom surface of the air conditioning unit Water backflow and easy immersion in the blower

[0011] However, according to the research of the inventors, in the air conditioning unit described in Patent Document 1, the guide wall acts as a ventilation resistance for the air passing through the duct, resulting in a decrease in the volume of the air blown into the vehicle interior.
