Problems solved by technology

However, there is a problem that the fitting portion of the two casings needs to be set at a position where the heat exchange medium pipe penetrates through the casing, the degree of freedom in setting the formation position of the fitting portion is reduced, or the fitting portion becomes complicated. shape
In addition, since the shape of the fitting portion becomes complicated, the fitting portion is easily deformed, which adversely affects the ease of installation when the two housings are attached.
In addition, the water condensed on the heat exchange medium piping is easy to transfer and flow in the fitting part due to capillary phenomenon
These problems are caused by the structure where the air conditioner casing is divided at the position of the heat exchange medium piping.

[0036] refer to Figure 1 to Figure 8 The vehicle air conditioner 100 of the first embodiment will be described. Such as figure 1 As shown, the vehicle air conditioner 100 includes an air conditioner case 1 that forms an air passage inside and accommodates various functional components. The air conditioner housing 1 is formed by combining multiple housing parts. The air conditioner case 1 is formed by combining at least the first case member 2 and the second case member 3 in the vertical direction at the fitting portion 30 . The first case member 2 is disposed on the upper side of the vehicle, and the second case member 3 is disposed on the lower side of the vehicle.

[0037] The first case member 2 and the second case member 3 form a fitting portion 30 extending in the vehicle left-right direction. For example, the fitting portion 30 is a portion where a protrusion formed on a joint end surface of one case member fits into a groove formed on a joint end surface of the oth...

[0079] In the second embodiment, refer to Figure 9 and Figure 10 A vehicle air conditioner 200 that is another form of the first embodiment will be described. The vehicle air conditioner 200 of the second embodiment is different in that when the evaporator 11 is installed on the first case member 102, the other end 111 on the side opposite to the pipe connection portion 113 is brought forward and enters the evaporator 11. to the first housing part 102 . In the second embodiment, components and unexplained structures assigned the same symbols as those in the drawings of the first embodiment are the same as those of the first embodiment, and have the same effects. In the second embodiment, configurations and the like that are different from those in the first embodiment will be described. Figure 9 and Figure 10 In order to facilitate understanding of the situation when the evaporator 11 is installed, the first case member 102 is shown broken so that only the inside of th...

Abstract

An air conditioner (100) for a vehicle includes: an air conditioner case (1) formed by combining a plurality of case parts; Connecting part (113). The first housing part (2) of the plurality of housing parts is provided with a connecting wall part (22) having a side wall (23) extending from one side of the installation opening part (20) to the inner side wall (23). the guide surface. The evaporator (11) is accommodated inside the first case member (2) in such a way that the air passage surface (110a) is inclined relative to the guide surface, and the portion of the evaporator (11) close to the installation opening (20) Compared with the part of the evaporator (11) close to the inner side wall (23), it is farther away from the connecting wall part (22).

Description

technical field [0001] The invention in this specification relates to a vehicle air conditioner that accommodates a heat exchanger inside a casing formed by combining a plurality of casing members. Background technique [0002] The vehicle air conditioner disclosed in Patent Document 1 has an air conditioner case formed by combining a fixed side case and a detachable side case. When the detachable-side case is attached to the fixed-side case, the first divided opening of the fixed-side case and the second divided opening of the detachable-side case are aligned with each other to form a case opening. The heat exchange medium piping of the evaporator accommodated in the air conditioning case penetrates through the opening of the case, and extends from the inside of the air conditioning case to the outside. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2008-105641 [0006] The problem to be solved by the in...
