Description: Technical Field This invention relates to an instrument panel module and an automotive air conditioner, which are capable of improving working efficiency of a vehicle production line, in particular, according to the features of the preamble of the independent claims. Background Art As means for improving working efficiency of vehicle production lines, a so-called instrument panel module has come to draw attention (Japanese Laid-Open Patent Publication (Kokai) No. 6-227238). The instrument panel module is formed by integrating an instrument panel and an automotive air conditioner or the like, into a unit. There has been conventionally used an automotive air conditioner which is comprised of an intake box for introducing air, a blower for blowing air from the intake box, an evaporator for cooling the air introduced by the blower from the intake box, a heater core for heating the air introduced by the blower from the intake box, an air-mixing door for adjusting the proportion between air passing through the heater core and air not passing through the same, a mode door for distributing the cooled or heated air, and a casing accommodating these devices. The evaporator has a refrigerant pipe connected thereto, and the heater core has a hot water pipe connected thereto. The refrigerant pipe and the hot water pipe are connected to a refrigerant pipe and a hot water pipe of an engine room, on a vehicle production line. The casing has the blower connected to a blower connection port thereof. The casing defines therein a cold air bypass passage where the air having passed the evaporator flows, a hot air passage where the air having passed through the heater core flows, and an air-mixing space where the air flowing from the cold air bypass passage and the air flowing from the hot air passage are mixed. The air-mixing space is located downstream of the air-mixing door. The casing is formed with a defroster outlet, a vent outlet, and a foot outlet, at respective locations downstream of the air-mixing space. The instrument panel module is a unit formed by integrating an automotive air conditioner with the instrument panel, as described above, and therefore, it is expected that the mounting of the instrument panel module in a vehicle should require less labor than the mounting of the two components separately in a vehicle on a vehicle production line. However, after the vehicle is supplied to market as a finished product, when the instrument panel is removed for maintenance, the automotive air conditioner has to be removed together with the instrument panel. Therefore, compared with the case of removing the instrument panel alone, the labor of workers is increased by an amount required for removing components of the conditioner, such as a refrigerant pipe and a hot water pipe, and the operations therefor become troublesome. The EP-A-0704329 discloses an instrument panel module including an automotive air conditioner including a casing, and an instrument panel adjacent to said automotive air conditioner, according to the features of the preamble of independent claim1 of the present application. An object of the present invention is therefore to provide an instrument panel module and an automotive air conditioner which can reduce labor of workers for removing an instrument panel for maintenance purposes.

Best Mode of Carrying Out the Invention The invention will now be described in detail with reference to drawings showing preferred embodiments thereof. FIG. 1 is a longitudinal cross-sectional view of an instrument panel module according to a first embodiment of the invention in a state in which it is mounted in an automotive vehicle, FIG. 2 is an exploded view of a separated state of the instrument panel module shown in FIG. 1, FIG. 3 is a view of an instrument panel-side part of a casing of an automotive air conditioner in a state joined to an instrument panel, FIG. 4 is a view of a fire panel-side part in a state joined to the instrument panel-side part of the casing of the automotive air conditioner, and FIG. 5 is a view of the instrument panel module in a state prior to being mounted to the vehicle. A fire panel Fi partitions an engine room ER and a compartment R. The instrument panel module is arranged within the compartment R. The instrument panel module shown in these figures is formed by integrating the automotive air conditioner A with the instrument panel IP. The instrument panel IP is integrally formed with ducts Dd, Dv. Further, mounted on the instrument panel IP are a control panel, a navigation device, an audio unit, an ash tray, etc, and a steering member S which extends in a left-right direction of the vehicle is supported thereby. The casing 1 of the automotive air conditioner A can be separated into two parts: fire panel-side part (or fire panel-side casing) Fp and an instrument panel-side part (or instrument panel-side casing) Rp. The instrument panel-side part Rp can be attached to the fire panel-side part Fp from one direction (see FIG. 7), and the instrument panel-side part Rp can be detached from the fire panel-side part Fp in the one direction (see FIG. 6). In this embodiment, it is possible to carry out the mounting and removal substantially along a front-rear direction BB of the vehicle. A connecting surface 1a of the fire panel-side part Fp and a connecting surface 1b of the instrument panel-side part Rp are firmly connected to each other via a sealing member (not shown), such as urethane resin, by fixing means (not shown), such as screws. In FIG. 1, for explanation purposes, the connecting surface 1a and the connecting surface 1b are shown separate from each other. The fire panel-side part Fp has a blower (blowing means) 3 and an evaporator (cooling means) 5. The fire panel-side part Fp has an intake box (not shown) connected thereto which forms part of air-introducing means. The intake box is formed with an internal air-introducing port and an external air-introducing port, neither of which is shown, and an internal/external air-switching door is provided within the intake box. The air-introducing means is comprised of the intake box and the internal/external air-switching door. The blower 3 sends air introduced into the intake box to the evaporator 5. Part of a motor (not shown) for rotating a fan 3a protrudes out of the casing 1. The evaporator 5 is an heat exchanger for cooling air from the fan 3a. The instrument panel-side part Rp has an air-mixing door 6, a heater core (heating means) 7, and mode doors M1, M2 (air-separating means). A driving mechanism (not shown) for driving these devices is attached to an outer wall of the instrument panel-side part Rp. The air-mixing door 6 adjusts the proportion between air passing through the heater core 7 and air not passing through the same. The heater core 7 is a heat exchanger for heating air from the evaporator 5. The instrument panel-side part Rp is provided with a defroster outlet d, a vent outlet v, and a foot outlet f. The defroster outlet d and the vent outlet v are located in an upper part of the instrument panel-side part Rp, and the foot outlet f is located in a lower part of the instrument panel-side part Rp, whereby the air is distributed into the cabin space of the compartment R from the respective outlets d, v, f via the ducts Dd, Dv, and a duct Df. The outlets d, v, f are opened and closed by the mode doors M1, M2. In this first embodiment, air conditioner components, such as the evaporator 5, the air-mixing door 6, the heater core 7 and the mode doors M1, M2, are classified (into groups) by paying attention to maintainability (ease of maintenance) or workability of mounting to the vehicle (ease of mounting to the vehicle), whereby the evaporator 5 and the heater core 7 belonging to piping-related air conditioner components (first group) are assigned to the fire panel-side part Fp, while the air-mixing door 6, and the mode doors M1, M2 belonging to mechanism-related air conditioner components (second group) are assigned to the instrument panel-side part Rp. It should be noted that the fire panel-side part Fp and the instrument panel-side part Rp can be separated in the left-right direction of the vehicle, and the left and right casing component parts constituting the fire panel-side part Fp and the instrument panel-side part Rp are fixed in the left-right direction by fixing means (not shown) such as tapping screws. This feature of the construction also applies to the other embodiments of the invention including a second embodiment. Further, upper, intermediate and lower parts of the instrument panel-side part Rp are integrally connected to the instrument panel IP by bolts B1, B2, B3. The upper part of the instrument panel IP is fixed to a cowl Ca by bolts, not shown, and the upper part of the same is fixed to the floor panel F1 by bolts, not shown. Next, the assembling of the instrument panel module and attaching (mounting) of the same to the vehicle will be described. The instrument panel module has three parts thereof separated before assembly (see FIG. 2). First, the instrument panel-side part Rp and the instrument panel IP are connected to each other (see FIG. 3). Then, the fire panel-side part Fp and the instrument panel-side part Rp are connected to each other. At this time, the connecting surface 1a of the fire panel-side part Fp and the connecting surface 1b of the instrument panel-side part Rp are abutted with each other via a sealing member, and the connecting surfaces 1a, 1b are joined by fixing means, not shown, (see FIG. 4). By the above procedure, the instrument panel IP, the instrument panel-side part Rp and the fire panel-side part Fp are integrated with each other to complete one instrument panel module. Thereafter, the instrument panel module is mounted on the vehicle in a state shown in FIG. 4 on a vehicle production line. At this time, the fire panel-side part Fp is fixed to the fire panel Fi by bolts, not shown, and a connector 9 of the refrigerant pipe 5a of the evaporator 5 is fixed to the fire panel Fi. The refrigerant panel 5a is connected to the refrigerant pipe 5b of the engine room ER. Further, the upper part of the instrument panel IP is fixed to the cowl Ca by bolts, not shown, and the lower part of the same is connected to the floor panel F1 by bolts, not shown. FIG. 6 is a view of the instrument panel-side part in a state separated from the fire panel-side part of the casing of the automotive air conditioner. In the first embodiment, the air-mixing door 6 and the mode doors M1, M2 are assigned to the instrument panel-side part Rp, and the evaporator 5 and the heater core 7 are assigned to the fire panel-side part Fp. This makes it only necessary, when the maintenance of the air-mixing door 6 and the mode doors M1, M2 is carried out, that only the instrument panel-side part Rp is removed, leaving the fire panel-side part Fp (see FIG. 6). Therefore, it is not necessary to separate the refrigerant pipe 5a of the compartment R and the refrigerant pip 5b of the engine room ER from each other, separate a hot water pipe 7a of the compartment R and a hot water pipe 7b of the compartment ER from each other, or remove electric chords (not shown) of the blower 3. Therefore, it is not required to drain engine coolant. The assembly of the instrument panel module and mounting of the same to the vehicle can be carried out by other methods than the above. Although in the above-described method, the instrument panel module, which has been formed by integrating the instrument panel IP, the instrument panel-side part Rp and the fire panel-side part Fp with each other, is conveyed into the vehicle production line, this is not limitative, but there may employed another method in which the instrument panel module is conveyed into the vehicle production line, with only the instrument panel IP and the instrument panel-side part Rp being integrated with each other, and the fire panel-side part Fp being not joined to the instrument panel IP. In this case, the mounting of the instrument panel module to the vehicle is carried out in the following manner: First, the fire panel-side part Fp is mounted on the vehicle. At this time, the fire panel-side part Fp is fixed to the fire panel Fi by bolts, and the connector 9 of the refrigerant pipe 5a of the evaporator is fixed to the fire panel Fi. The refrigerant pipe 5a is connected to the refrigerant pipe 5b of the engine room ER. Then, as shown in FIG. 7, the instrument panel-side part Rp integrated with the instrument panel IP is joined to the fire panel-side part Fp, while the upper part of the instrument panel IP is screwed to the cowl Ca, and the lower part of the same is screwed to the floor panel F1. According to this procedure of assembly, the assembly work on the vehicle production line is further facilitated, and the labor of the work is reduced. In particular, this method is more effective when applied to an automotive air conditioner comprised of a larger number of air conditioner components, such as the evaporator 5, accommodated within the casing 1. Next, the operation of the instrument panel module described above will be described. When the air-mixing door 6 and the mode doors M1, M2 are in position indicated by solid lines, as shown in FIG. 1, a cold air bypass passage C is blocked, and all the air having passed through the evaporator 5 flows toward the heater core 7. The air is heated when passing through the heater core 7, and flows from a hot air passage H through a duct Df to the foot outlet f, from which it is blown into the cabin of the compartment R. When the air-mixing door 6 and the mode door M2 are in position indicated by phantom lines in FIG. 1, and the mode door M1 is in position indicated by solid lines, the air having passed through the evaporator 5 does not pass through the heater core 7 but pass through the cold air bypass passage C to the vent outlet V, from which the air flows through the duct Dv and is blown into the cabin space of the compartment R. According to this first embodiment, since the casing 1 is configured such that it is separable into the fire panel-side part Fp and the instrument panel-side part Rp, the mounting of the instrument panel module to the vehicle is facilitated and at the same time, the whole automotive air conditioner is not required to be separated from the vehicle when the maintenance is carried out, whereby the working hours and manufacturing costs can be reduced (effects (1)). Further, since the instrument panel-side part Rp can be removed from the fire panel-side part Fp in one direction, whereby the maintainability is improved (effects (2)). Moreover, since the instrument panel-side part Rp can be mounted to the fire panel-side part Fp from the one direction, the mounting workability is further improved, and the connecting surfaces 1a, 1b of the fire panel-side part Fp and the instrument panel-side part Rp are difficult to be displaced from each other, whereby the sealing properties are improved (effects (3)). Further, the air conditioner components including the evaporator 5, the heater core 7, and the mode doors M1, M2, are classified by paying attention to maintainability or mounting workability, into a piping-related group, and a mechanism-related group, and air conditioner components belonging to the piping-related group are assigned to the fire panel-side part Fp, while air conditioner components belonging to the mechanism-related group are assigned to the instrument panel-side part Rp. This facilitates the work of mounting the instrument panel module to the vehicle, and at the same time, makes it unnecessary to remove the whole automotive air conditioner from the vehicle when the maintenance is carried out, whereby the working hours and manufacturing costs can be reduced. Except when the maintenance of the evaporator 3 and the heater core 7 are subjected to maintenance, there is no longer the waste of the refrigerant and the coolant due to drainage thereof carried out whenever the instrument panel IP is removed, which meets the requirement of saving of resources (effects (4)).

The casing 301 has a blower-connecting port 30 thereof connected to the outlet port of the blower. The evaporator 5 and the heater core 7 are arranged substantially vertically. The evaporator 5 is located on a front side of the heater core 7 with respect to the front-rear direction BB of the vehicle. The evaporator 5 has the refrigerant pipe 5a connected thereto, and the heater core 7 has the hot water pipe 7a connected thereto. The refrigerant pipe 5a and the hot water pipe 7a are connected to a refrigerant pipe and a hot water pipe, neither of which is shown, of an engine room, on a vehicle production line. The casing 301 defines therein the cold air bypass passage C where the air having passed the evaporator 5 flows, the hot air passage H where the air having passed through the heater core 7 flows, and an air-mixing space MX where the air flowing from the cold air bypass passage C and the air flowing from the hot air passage H are mixed. The air-mixing space MX is located downstream of the air-mixing door 6. The air-mixing door 6 is driven by a drive mechanism, not shown. The casing 301 is formed with the defroster outlet d, the vent outlet v, and the foot outlet f, at respective locations downstream of the air-mixing space MX.

Next, the operations and effects of this instrument panel module will be described. When the fan of the blower is rotated, the air is introduced into the casing 301 from the blower-connecting port 30. The air introduced into the casing 301 flows toward the evaporator 5. In the air-mixing mode, the air-mixing door 6 is in an intermediate position between the fully-opened position and the fully-closed position, whereby part of the air having passed through the evaporator 5 flows through the cold air bypass passage C toward the air-mixing space MX, and the remainder of the air flows toward the heater core 7. The air is cooled when passing through the evaporator 5. The air having passed through the heater core 7 flows through the hot air passage H toward the air-mixing space MX. The air is heated when passing through the heater core 7. The air downstream of the cold air bypass passage C and the air downstream of the hot air passage H flow into each other in the air-mixing space MX, and mixed with each other, and the resulting mixture flows to one(s) of the outlets d, v, f associated with a selected one of the blowing modes. Next, description will be given of a manner of removing the instrument panel IP to carry out maintenance after the vehicle having this instrument panel module mounted thereon is supplied to market. To remove the instrument panel IP, the fixing means are removed so as to enable the casing 301 to be separated from each other into the fire panel-side part Fp and the instrument panel-side part Rp.
