no. 1 approach

[0044] first of all, yes figure 1 , 2 The schematic structure of the whole air-conditioning unit 10 of this embodiment shown is demonstrated. The air conditioning unit 10 is a vehicle air conditioning unit constituting a part of the vehicle air conditioner. This air conditioning unit 10 is mounted on the front side of the vehicle rather than the front seats in the vehicle interior. More specifically, this air conditioning unit 10 is arranged inside the instrument panel. The air conditioning unit 10 blows the air that has passed through the heat exchanger toward the vehicle interior.

[0045] The air conditioning unit 10 includes an air conditioning case 12 , a blower (not shown), an evaporator 14 , a heater core 16 , and a PTC heater 18 .

[0046] The air conditioning case 12 constitutes an outer casing of the air conditioning unit 10 . like figure 1 As shown, a plurality of blowing openings 20 , 22 , 24 are formed in the air conditioner case 12 . The plurality of blowi...

no. 2 approach

[0074] like Figure 7 As shown, the present embodiment differs from the first embodiment in that the adjustment member 40 has the baffle 48 . Other configurations of the air conditioning unit 10 are the same as those of the first embodiment.

[0075] The two adjustment members 40 respectively have a frame 42 , a grid 44 and two baffles 48 . The baffle 48 is a plate member that blocks air flow.

[0076] The grid 44 and the two baffles 48 are arranged in an area surrounded by the frame 42 . The two baffles 48 are arranged in a part of the peripheral portion of the central portion in the area surrounded by the frame 42 . Therefore, the baffle 48 is arranged offset in the area surrounded by the frame 42 . The grid 44 is arranged in the area surrounded by the frame 42 except for the two baffles 48 . The frame 42, the grid 44, and the two baffles 48 are constituted by an integral molding made of resin. These may also not be made of resin.

[0077] The lattice area 47 where th...

no. 3 approach

[0095] Such as Figure 9 As shown, in the present embodiment, a plurality of openings 48a are formed in the two shutters 48 for each of the two adjustment members 40 . Other configurations of the air conditioning unit 10 are the same as those of the first embodiment.

[0096] In this way, a plurality of openings 48 a may be formed in the baffle 48 . There may be one opening 48a. By forming one or more openings 48 a in the baffle 48 , resistance to air flow in the baffle region 49 can be reduced. Accordingly, it is possible to adjust the resistance to the airflow of the blowing opening provided with the adjustment member 40 .

Abstract

An air conditioning unit (10) is provided with: an air conditioning case (12) having formed therein discharge openings (201, 203) for discharging air; a cooler provided within the air conditioning case and cooling air flowing toward the discharge openings; a heater provided within the air conditioning case and heating air flowing toward the discharge openings; and regulation parts (40) provided atthe discharge openings and regulating air flows which pass through the discharge openings. The regulation parts have formed therein first regions through which air flows, and second regions which have greater resistance to air flow than the first regions.

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2017-165846 for which it applied on August 30, 2017, and the description content is incorporated in this application by reference here. technical field [0003] The invention relates to an air conditioning unit for a vehicle. Background technique [0004] Patent Document 1 has invented an air-mixing type air conditioning unit. This air conditioning unit mixes cold air generated by a cooler and warm air generated by a heater to send air-conditioned air whose temperature has been adjusted into the vehicle interior. [0005] prior art literature [0006] patent documents [0007] Patent Document 1: Japanese PCT Publication No. 2006-510548 [0008] In recent years, due to the miniaturization of air conditioning units, the space for mixing cold air and warm air inside the air conditioning units has become smaller. Therefore, warm air and cold air are blown out...
