Abstract

PURPOSE:To facilitate maintenance and inspection of an interior blower assembly and cleaning work of an interior heat exchanger in an interior unit in a separate type vehicle air conditioner. CONSTITUTION:In a vehicle 1, a separate type vehicle air conditioner 4 is arranged on the vehicle ceiling integrally with a vehicle main body. A bottom plate 8 supporting an interior blower assembly 6 works for receiving condensed water generated in an interior heat exchanger 7. The bottom plate 8 is supported in an interior unit casing 5 by means of a hinge 9 and a bolt 10. Therefore, as the bottom plate 8 is supported in the interior unit casing 5 by means of the hinge 9, maintenance and inspection of the interior blower assembly 6 and cleaning of the interior heat exchanger 7 can be easily carried out only by turning the bottom plate 8 in the vertical direction.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separate type vehicle air conditioner indoor unit suitable for being installed integrally with a vehicle body on a vehicle ceiling.

[0002]

2. Description of the Related Art Conventionally, an indoor unit of a separate type air conditioner for a vehicle is installed by being buried in the ceiling of a fourth vehicle. That is, the housing of the indoor unit in which the indoor heat exchanger, the indoor blower, etc. are installed is installed in the ceiling and is covered with the ceiling plate. (JP-A-4-10806
(Gazette No. 3)

[0003]

In the indoor unit of the conventional separate type air conditioner for a vehicle described above, the ceiling plate is removed and the bottom plate of the housing is removed to perform maintenance of the indoor blower, and the bottom surface of the indoor unit 4 is removed. Was opened and the indoor blower was removed.

When cleaning the indoor heat exchanger,
Similar to the above, the dew tray was removed after the bottom of the indoor unit was opened.

For this reason, the work required a considerable amount of time. Further, the work of removing the bottom plate is too large for one worker to support, and the work of removing the bolt with one worker who supports the bottom plate because the fixing bolts are located at the left and right ends of the bottom plate. Two people were required, one person. The work of removing the indoor blower was also performed by two operators because the weight of the indoor blower assembly 6 was too heavy for one operator to handle.

The present invention has been made to solve the above problems, and improves workability so that maintenance and inspection of the indoor blower 6 and cleaning of the indoor heat exchanger can be performed by one person in a short time. An object is to obtain an indoor unit of a separate type air conditioner for a vehicle.

[0007]

In order to achieve the above object, in the indoor unit of a separate type air conditioner for a vehicle of the present invention, the bottom plate forming the bottom surface of the indoor unit supports the indoor blower, and By adopting a structure in which the bottom plate can be pivoted in the vertical direction by means of a hinge, the indoor blower assembly, which was inside the indoor unit, comes out of the indoor unit as the bottom plate rotates.
Further, the bottom plate forms a dew tray for receiving condensed water generated in the indoor exchanger, so that the bottom surface of the indoor heat exchanger is opened as the bottom plate rotates.

[0008]

In the present invention, in the indoor unit of the separate type air conditioner for a vehicle, while supporting the indoor blower,
The bottom plate forming a dew tray for receiving condensed water is supported on the indoor unit housing by a hinge on one side and a bolt on the other side.

Therefore, by removing the bolt, it can be rotated in the vertical direction. With this structure, if you remove the bolt on one side that fixes the bottom plate and rotate the bottom plate vertically, the indoor blower assembly will come out of the indoor unit for maintenance and indoor heat exchanger. The bottom surface of the indoor heat exchanger is released, and the indoor heat exchanger can be washed from the bottom surface direction of the indoor unit. Since the bolt located on one side of the bottom plate can be removed by one person,
It is possible to reduce the number of workers who used to work with two people in the past and to shorten the working time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. In FIG. 1, 1 is a vehicle, 2 is a vehicle ceiling surface, and 3 is an inspection ceiling panel, which can be removed for maintenance and inspection. Reference numeral 4 denotes an indoor unit of a separate type vehicle air conditioner, which is installed integrally with the vehicle body on the vehicle ceiling. Reference numeral 5 is an indoor unit housing, and 6 and 7 are an indoor blower assembly and an indoor heat exchanger housed in the housing. Here, the indoor blower assembly 6 includes an indoor blower and an electric motor that drives the indoor blower. Reference numeral 8 denotes a bottom plate forming the bottom surface of the indoor unit 4, which supports the indoor blower assembly 6 and also has the function of a dew tray for receiving condensed water generated in the indoor heat exchanger 7. And
The portion of the dew tray is connected to the drain pipe 14, and the condensed water is drained to the outside of the vehicle through the drain pipe 14. Further, a drain hole 15 is provided at the bottom of the dew tray, but this is for draining condensed water which is carried out in advance when the bottom plate 8 is removed, and is normally covered with a cap 16. ing. The bottom plate 8 is supported by the indoor unit housing 5 on one side by hinges 9 and on the other side by bolts 10. At this time, the periphery of the bottom plate 8 is surrounded by the indoor unit housing 5 and the sheet.
The structure is such that the air that is flowed through the indoor heat exchanger 7 does not leak to the outside of the indoor unit 4.

FIG. 2 is a sectional view taken along the line AA in FIG. 1 showing this seal structure, and the abutting portion of the indoor unit 5 and the bottom plate 8 is sealed by a packing 17. However, since this structure cannot be adopted for the hinge 9, the elastic body such as rubber 18 is used to close the gap between the indoor unit housing 5 and the bottom plate 8. Here, by removing the bolt 10, the bottom plate 8 can be rotated vertically in the vertical direction as indicated by an arrow B shown in FIG.

In the indoor unit 4 of the separate type air conditioner for a vehicle thus constructed, first, the cap 16
To remove the condensed water from the drain hole 15, and then remove the connection between the drain pipe 14 and the dew tray portion of the bottom plate 8. After that, if only the bolt 10 is removed, the bottom plate 8 can be rotated in the B direction, so that the indoor blower assembly 6 can be taken out of the indoor unit 4. Therefore, the maintenance and inspection of the indoor blower assembly 6 becomes possible. At the same time, since the bottom surface of the indoor heat exchange 6 can be released,
The indoor heat exchanger 7 can be washed from the bottom surface direction of the indoor unit 4. In this way, it is no longer necessary to remove the indoor blower assembly 6 and the dew tray 11 from the indoor unit housing 5 as has been done conventionally. Also, remove the bolt 10,
The operation of rotating the bottom plate 8 can be performed by one person because one side of the bottom plate 8 is supported by the hinge 9. Maintenance and inspection of the indoor blower assembly 6 and cleaning of the indoor heat exchanger 7 itself can be performed by one person, so maintenance and inspection of the indoor blower assembly 6 and indoor heat that conventionally required two workers. The cleaning operation of the exchanger 7 can be performed by one person.

[0013]

INDUSTRIAL APPLICABILITY The present invention has a structure in which a bottom plate that supports an indoor blower and also serves as a dew tray pivots in a vertical direction by a hinge. There is an effect that the maintenance work of the indoor blower assembly and the cleaning work of the indoor heat exchanger are facilitated and can be performed by one person.
