Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a vehicle air conditioner.

[Prior Art] Generally, vehicle air conditioners are often retrofitted as an option.
Like the ventilation duct support structure in No. 93961 (Japanese Patent Publication No. 61-45563), the air conditioner main body and duct are attached using the internal space of the instrument panel.
That is, the main body of the air conditioner, which consists of a heater, a refrigerant evaporator, a temperature control shutter, etc., is arranged at the center bottom of the instrument panel, and the main body of the air conditioner and the plurality of air outlets arranged on the instrument panel are connected by a duct. .

In conventional air conditioners, it is difficult to install wires, ducts, etc. for operating the outlet switching shutter and temperature control shutter inside the instrument panel, and it takes a lot of time and effort.

As disclosed in Utility Model Application Publication No. 57-57106,
There is a method in which the entire upper wall panel of the instrument panel is removable, and a duct plate with passage grooves is attached to the lower side of the panel, but this method is used to attach various electrical devices, radios, operation panels, etc. to the upper surface of the instrument panel. It is difficult to apply to

[Problems to be solved by the invention] The purpose of the invention was devised in view of the above-mentioned problems, and is intended to solve the problem when inspection, maintenance, and replacement of the adjustment plate attached to the central outlet or side outlet is required. There is no need to disassemble the entire instrument panel, and the inspection, maintenance, and replacement work can be done by opening the lid or removing only the lid, and the inspection, maintenance, and replacement work is facilitated. By eliminating the need to install the duct at the bottom, it is possible to effectively utilize the lower part of the instrument panel and expand the leg space for the occupants, and the lid body has a multilayer structure, which has the effect of increasing its rigidity and strength. When retrofitting an air conditioner to a vehicle equipped with an opening for communicating with the air outlet of the device main body, a lid body without an air outlet is replaced with a lid body provided with the central air outlet and the side air outlet. In addition, it is only necessary to attach the duct to the inner surface of the lid body, and there is no need to remove and replace the entire instrument panel including various electric devices, radios, air conditioner operation panels, etc., and the air conditioner can be retrofitted. An object of the present invention is to provide an effective vehicle air conditioning system that can quickly and easily perform air conditioning.
