Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a heater unit for a vehicle air conditioner that facilitates connection of ducts.

(Prior Art) Conventionally, the heater unit is arranged inside the instrument panel as is well known, and the air blown from the connection port is directed to each outlet of the heater unit toward the outlet provided on the instrument panel. It has a structure in which ducts that guide air are connected.

(Problems to be Solved by the Invention) As described above, since the heater unit is arranged inside the instrument panel, after the heater unit main body is mounted on the vehicle body in the assembly line, the duct and the instrument including the peripheral functional parts are installed. Ment panel is assembled. In this case, the duct is connected to the connection port of the heater unit main body, but the duct is temporarily supported inside the instrument panel in advance, and the instrument panel is mounted while being temporarily supported. Since the ducts are aligned at the same time as the instrument panel is aligned at the time of mounting, there is a problem that it is very troublesome to properly align the duct, which is difficult to see inside, with the connection port.

In addition, the heat control body that is assembled to the instrument panel and the control part appears on the surface requires a special lifting tool to support it with a lifting tool so that it does not get scratched when it flows through the assembly line from the location to be installed later. Met.

Then, this invention aims at providing the heater unit of the vehicle air conditioner provided with the support function which supports a heater control main body, and the guide function which facilitates connection of a duct.

[Means for Solving the Problem] (Means for Solving the Problems) In order to achieve the above object, in the present invention, a heater unit main body having a connection port for connecting a duct is provided on both sides of the connection port. The support brackets that temporarily support both ends of the heater control main body that are arranged are projected, and the insides of the left and right support brackets serve as guide guide surfaces that guide the connecting portions of the duct toward the connecting ports.

(Operation) In such a heater unit, the left and right sides of the heater control main body are temporarily supported by the support bracket so that the heater control main body is transported without being damaged. Next, after removing the heater control main body from the temporary support bracket, install the instrument with the duct connection part facing the connection port, and the connection part will be guided by the guide surface to be properly aligned with the connection port. The combined state obtained is obtained. Then, the heater control body is attached to complete the process.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to the drawings of FIGS. 1 to 4.

In the figure, 1 indicates a heater unit, which is a unit main body 1a.
Inside, functional parts such as a heater core and a control door (neither of which is shown) for controlling the amount of air flowing through the heater core are provided, while having a connection port 3 through which air conditioned by the control door is blown out. There is.

A sealing member 9 made of polyurethane or the like is provided around the connection port 3 to secure a seal when the duct 5 is connected to the connection portion 7. Further, the first and second support brackets 11 are provided on both left and right sides of the connection port 3. , 13 are protruding.

Of the left and right support brackets 11 and 13, the first support bracket 11 has a support portion 12 on the inner side, and is a sideways U when viewed from the side.
It is shaped like a letter. The second support bracket 13 is bent and extended outward in a crank shape from the unit main body 1a, and the tip portion 15 rises upward. The tip portion 15 functions as a stopper that restricts the mounting brackets 19 and 19 of the heater control main body 17 from coming off during temporary support.

The inner side 11a of the first support bracket 11 and the inner side 13a of the base of the second support bracket 13 serve as guide guide surfaces 21, 21 for guiding the connecting portion 7 of the duct 5 to the connecting port 3 of the unit body 1a. The guide guide surfaces 21, 21 are tapered so that the width becomes gradually narrower toward the connection port 3 of the unit main body 1a when seen in a plan view.

In addition, depending on the shape of the heater control body 17, the second
The support bracket 13 may be formed in a linear shape as shown by the chain line in FIG.

After mounting the unit main body 1a on the vehicle body in the heater unit 1 thus configured, the heater control main body
Both ends of the mounting brackets 19, 19 of 17 are temporarily supported by the first and second support brackets 11, 13. As a result, the heater control body 17 can be transported without being damaged.

Next, in the assembly process of the duct 5, after temporarily removing the heater control main body 17, the instrument panel 23
To the body panel. At this time, if the instrument panel 23 is attached with the connecting portion 7 of the duct 5 temporarily supported inside the instrument panel 23 corresponding to the connection port 3, the connecting portion 7 of the duct 5 will be connected to the guide surface 21. Guided by 21, a connection state is obtained in which the connection port 3 is correctly aligned. Therefore, the work of fixing the duct 5 can be completed quickly. Then the heater control body 17
Installation work can be done easily without damaging it.

[Advantages of the Invention] As described above, according to the heater unit of the present invention, the heater control main body can be temporarily supported by the left and right support brackets, and the duct guide portion and the unit main body are formed by the inner guide surface. The connection with the connection port of is correct, and it can be easily performed, thus improving the work efficiency.
