Air Conditioning Units for Vehicles

Abstract

The invention discloses an air-conditioning apparatus for vehicle, which is small in size and easy in the assembling and disassembling of a fiter. The air-conditioning apparatus is provided with: a casing which has an air corridor; an assembling and disassembling opening portion which is used for assembling and disassembling the fitler; a lower side guide portion which is configured from an opposite wall with respect to the assembling and disassembling opening portion to the assembling and disassembling opening portion; a lower side mounting portion which is formed on the opposide wall side; a lower side rail portion which is formed on the assembling and disassembling opening portion side of the lower side mounting portion such that the lower side rail portion and the lower side mounting portion intersects with each other at an angle of larger than 180 DEG on an upper side; an upper side guide portion; an upper side mounting portion which is formed on the opposide wall side; a first upper side rail portion which is formed on the assembling and disassembling portion side of the upper side mounting portio such that the first upper side rail portion and the lower side mounting portion are left with a gap which spreads towards the assembling and disassembling opening portion side; a second upper side rail portion which is formed approximate to the assembling and disassembling opening portion than the first upper rail portion such that the second upper side rail portion and the lower side mounting portion are left with a gap which shrinks towards the assembling and disassembling opening portion side.

Description

technical field [0001] The invention relates to a vehicle air conditioner for cooling and heating in a vehicle and preventing fog from being generated on a windshield glass and the like. Background technique [0002] The vehicle air conditioner mixes the cold air cooled by the evaporator and the hot air heated by the heater core in the mixing chamber to form air-conditioning air, and blows the air-conditioning air into the vehicle interior to provide comfortable cooling and heating for passengers. , Also prevent the front windshield, side windshield, etc. from fogging. The cooling and heating methods of the vehicle air conditioner are roughly divided into the internal air circulation mode in which the air inside the vehicle (inside air) is circulated by the blower of the vehicle air conditioner to perform cooling and heating, and the air taken in from the outside of the vehicle (outside air). ) outside air intake mode in which cooling or heating is performed for cooling or ...

Problems solved by technology

At this time, since the distance between the vicinity of the attachment and detachment opening 7a and the filter outer end 3b is short, it is extremely difficult to apply a force opposing the rotational force F.

[0017] The above-mentioned situation also occurs when the filter 3 is disassembled. Therefore, when the operator attaches and detaches the filter 3, he not only needs to apply a force in the direction of attachment and detachment of the filter 3, but also needs to apply a downward force to the filter outer end 3b. Therefore, loading and unloading operations are not easy
