[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear heater case structure for a vehicle rear heater.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 3, a conventional rear heater for a vehicle includes a rear heater unit 2 installed under a front seat (seat) 1 and a hot air from the rear heater unit 2 provided in the rear seat. 3 and a heat control panel 5 mounted on the rear heater duct 4 for controlling the temperature of hot air from the rear heater unit 2. I have.

The rear heater unit 2 includes a blower 6 for blowing air and a blower 6 for blowing air in a rear heater case 23 which is installed under the front seat 1 and includes an upper case 23a and a lower case 23b which can be divided into upper and lower parts. A heater core 7 for heating the air sent by the blower 6 is provided, and the air sent by the blower 6 is supplied to the hot water by adjusting the opening of an air mix damper (not shown). Is introduced at a desired ratio to the heater core 7 side into which the heater core 7 is introduced and the bypass side of the heater core 7 to generate wind at a temperature required by the occupant.

The heat control panel 5 is for adjusting the opening of the air mix damper of the rear heater unit 2 and, as shown in FIG. 3, a control cable 8 connected to the air mix damper. The outer cable 8a is fixed to the clamp 9 of the control panel main body 5a, and the inner cable 8b of the control cable 8 is connected to the operating portion 5c of the adjustment lever 5b pivotally attached to the control panel main body 5a. With a plurality of (three in the example in the figure) fastening bosses 10 projecting from the upper surface, a plurality of fastening holes 11 of the control panel body 5a are aligned with a fastening member 12 such as a tapping screw. By tightening, the control panel main body 5a is fixed on the rear heater duct 4, and the tip of the adjustment lever 5b is fixed. The slit 15 of the heat control plate 14 assembled to the rear console 13
The control knob 16
Are fitted.

In the figure, reference numeral 18 denotes a hot water supply pipe for supplying hot water after cooling the engine to the heater core 7, 17 a hot water discharge pipe for discharging hot water from the heater core 7, and 19 a power supply to the rear heater unit 2. Vehicle side harness, 20
Is a blower switch for turning on and off the blower 6 of the rear heater unit 2.

[0006]

In the case of a vehicle rear heater as described above, the blower 6 is attached to the rear heater case 23.
When assembling the centrifugal fan 24 and the motor 25, as shown in FIGS. 4 and 5, the upper case 23a in which the wire mesh 27 for preventing foreign matter is attached to the blower inlet 26 is attached.
The centrifugal fan 24 is set from below, and the motor 25 is set from above.
5 while fixing the centrifugal fan 24 to the shaft 25a of the motor 25 with a fixing member 28 such as a screw, and holding the wire mesh 27 by a bracket 29 projecting in the radial direction of the motor 25, Case 23
After the tightening member 32 such as a tapping screw is tightened in position with the boss 31a, the lower case 23b is attached to the upper case 23a.

However, in the structure of the rear heater case 23 as described above, the workability of assembling the centrifugal fan 24 and the motor 25 of the blower 6 to the rear heater case 23 is poor, and the wire mesh 27 as a separate member is required. The number of parts is increased, and the motor 25 is
Since the motor 25 is exposed to the upper part, the heat of the motor 25 is easily transmitted to the outside of the rear heater case 23.

In view of such circumstances, the present invention can improve the workability of assembling the centrifugal fan and motor of the blower to the rear heater case, and can reduce the number of parts by eliminating the need for a wire mesh as a separate member. An object of the present invention is to provide a rear heater case structure of a vehicle rear heater that can make it difficult to transfer heat of a motor to the outside of a rear heater case.

[0009]

According to the present invention, a centrifugal fan and a motor of a blower for blowing air are provided in a rear heater case which is provided under a seat and is composed of an upper case and a lower case which can be divided into upper and lower parts. A rear heater case structure of a rear heater for a vehicle, comprising a heater core for heating air sent by the blower, wherein a lattice portion is integrally formed at a blower suction port in an upper case of the rear heater case. In addition, the present invention relates to a rear heater case structure of a rear heater for a vehicle, wherein a motor cover for covering a blower motor is integrally formed at a central portion of a blower suction port in which the lattice is integrally formed.

According to the above means, the following effects can be obtained.

When assembling the centrifugal fan of the blower and the motor to the rear heater case, after fixing the centrifugal fan to the shaft of the motor, the centrifugal fan is fixed to the upper case in which the lattice portion and the motor cover are integrally formed. If the motor and the centrifugal fan are set from below, and the lower case is attached to the upper case, the work of assembling the centrifugal fan and the motor of the blower to the rear heater case is completed.

Further, since the motor is covered by the motor cover and is not exposed to the upper part of the upper case, the heat of the motor is less likely to be transmitted to the outside of the rear heater case.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of an embodiment of the present invention. In the drawings, the portions denoted by the same reference numerals as those in FIGS. 3 to 5
The present embodiment is the same as the conventional one shown in FIG. 1 except that the blower suction port 26 in the upper case 23a of the rear heater case 23 as shown in FIGS.
In addition, the grid portion 33 is integrally formed, and the motor cover portion 34 for covering the motor 25 of the blower 6 is formed integrally with the central portion of the blower suction port 26 where the grid portion 33 is integrally formed.

In the illustrated example, the lattice 33
Are formed in the circumferentially required places (three places in the example in the drawing) of the blower suction port 26 integrally formed with the blower, and a bracket of the motor 25 is provided on the inner surface side of each of the reinforcing parts 35. A boss 36 for tightening 29 is provided.

With the configuration described above, the centrifugal fan 24 of the blower 6 and the motor 25
When assembling, the centrifugal fan 24 is fixed to the shaft 25a of the motor 25 by a fixing member 28 such as a screw, and then the upper case 23a in which the lattice portion 33 and the motor cover portion 34 are integrally formed. The motor 25 from below
With the centrifugal fan 24 set and the motor 25
The holes 30 at the tips of the brackets 29 projecting in the radial direction are aligned with the bosses 36 on the inner surface side of the reinforcing portion 35, and the fastening members 32 such as tapping screws are tightened. Thereafter, the lower case 23b is attached to the upper case 23a. Is installed, the centrifugal fan 24 of the blower 6 with respect to the rear heater case 23
And the motor 25 is completed.

Since the motor 25 is covered by the motor cover 34 and is not exposed above the upper case 23a, the heat of the motor 25 is not easily transmitted to the outside of the rear heater case 23.

In this way, the workability of assembling the centrifugal fan 24 of the blower 6 and the motor 25 to the rear heater case 23 can be improved, and the number of parts can be reduced by eliminating the need for the wire mesh 27 as a separate member. Heat can be hardly transmitted to the outside of the rear heater case 23.

The structure of the rear heater case of the rear heater for a vehicle according to the present invention is not limited to the above-described example, and various modifications can be made without departing from the scope of the present invention. is there.

[0020]

As described above, according to the rear heater case structure of the vehicle rear heater of the present invention, the workability of assembling the centrifugal fan of the blower and the motor to the rear heater case can be improved, and as a separate member. It is possible to achieve an excellent effect that the number of parts can be reduced by eliminating the need for the wire mesh, and the heat of the motor can be hardly transmitted to the outside of the rear heater case.
