DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the present invention is embodied in an electric vehicle will be described below in detail with reference to FIG. In FIG. 1, reference numeral 1 denotes a vehicle driving motor of an electric vehicle, and a heating motor 2 is provided independently of the vehicle driving motor 1. In addition, this heating motor 2
Has a viscous heater 3 as a non-combustion heater described above.
And a circulation pump 4 for circulating a heat medium such as water.

Reference numeral 5 denotes an indoor heat exchanger, in which a heat exchanger (heater core) 5a for heating, an evaporator 5b for cooling, a fan 5c for air blowing inside the vehicle, a cooling / heating switching damper 5d and the like are provided. It is arranged. In this drawing, a cooling circuit for cooling is omitted. Reference numeral 10 denotes a heat medium circuit, which includes a viscous heater 3, a heater core 5a, and a circulation pump 4.
Are connected by piping. The heat medium circuit 1
At 0, the first heat recovery device 6 and the second heat recovery device 7 are connected between the circulation pump 4 and the viscous heater 3. The first heat recovery unit 6 is formed integrally with the housing of the heating motor 2,
, That is, the heat medium is heated by waste heat. Also,
The second heat recovery unit 7 is formed integrally with the housing of the vehicle running motor 1 and is
, That is, the heat medium is heated by waste heat. Accordingly, a heat medium circuit 10 is formed which is sequentially connected to the viscous heater 3, the heater core 5a, the circulation pump 4, the first heat recovery unit 6, the second heat recovery unit 7, and the viscous heater 3.

The operation of the heating device configured as described above is performed by driving the heating motor 2 and the blower fan 5c. First, when the heating motor 2 is driven, the viscous heater 3 generates heat by the frictional heat of the viscous fluid, and at the same time, the circulation pump 4 is driven. Further, the driving of the circulation pump 4 causes the heat medium to start circulating in the heat medium circuit 10. On the other hand, when the blower fan 5c of the indoor heat exchange unit 5 is driven, the air inside the vehicle is ventilated to the heater core 5a.

As described above, when the heating operation is started, the heat medium discharged from the circulation pump 4 is supplementarily heated by the heat of the heating motor 2 in the first heat recovery unit 6, and Waste heat is recovered. The heat medium exiting the first heat recovery device 6 enters the second heat recovery device 7. Therefore, when the vehicle running motor 1 is being driven, the second heat recovery unit 7 further assists the heating by the heat (waste heat) of the vehicle running motor 1. Then, the heat medium that has exited from the second heat recovery unit 7 enters the viscous heater 3 and is essentially heated.
The heat medium thus heated enters the heater core 5a of the indoor-side heat exchange unit 5, exchanges heat with the cabin air passing through the heat exchanger 5a to heat the cabin air, and then heats the cabin air. Return to.

According to the first embodiment, the heat medium is
Viscous heater 3 which is a non-combustion type heat generator, motor 1 for driving the vehicle, and heating motor 2 for driving the viscous heater
Therefore, there is no generation of combustion gas which causes air pollution from the heating heat source device. Also, the heat generated by the vehicle driving motor 1 and the heating motor 2 for driving the viscous heater is not directly discharged to the atmosphere as waste heat, but is recovered by a heat recovery device provided for each of the heat recovery devices. , The thermal efficiency is increased. Further, the motors 1 and 2 are also cooled, and the efficiency is improved. Further, since the heating motor 2 is independent of the vehicle traveling motor 1, the heating motor 2 can have an appropriate capacity corresponding to the heating load, and heating can be performed regardless of the driving of the traveling motor 1. it can. In addition, when the automobile is not running, the heating can be efficiently performed by the heating motor 2. Further, since the heating motor 2 for driving the viscous heater is also used as a drive source for the pump 4 for circulating the heat medium, a dedicated device for circulating the heat medium is omitted. Therefore, compared with a case where a drive motor for driving the heat medium circulation pump 4 is separately provided, the cost can be reduced accordingly.
Resources can be saved, space can be saved, and weight can be reduced.

Next, a second embodiment will be described with reference to FIGS.
It will be described based on. In the second embodiment, the present invention is embodied in a hybrid vehicle. In FIGS. 2 to 4, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be simplified.

As shown in FIG. 2, the hybrid vehicle has a traveling engine 11 and a vehicle traveling motor 1 as traveling driving sources, and both are connected by a transmission 16. The vehicle is configured to travel by using the traveling engine 11 during acceleration, and is switched to driving by the vehicle traveling motor 1 after being accelerated to a constant speed. In the second embodiment, the heat medium circuit 20 includes the first
As in the case of the embodiment, the viscous heater 3A (in this case, a variable-capacity viscous heater which also serves as a clutch means as described later), the heater core 5a, the circulation pump 4, the first heat recovery unit 6, the second heat recovery unit The main heat medium circuit is sequentially connected to the heat recovery unit 7 and the viscous heater 3A, and an engine cooling circuit is formed integrally with the main heat medium circuit.

That is, a three-way switching valve V1 is interposed in the pipe between the circulation pump 4 and the first heat recovery unit 6, that is, in the outlet pipe of the circulation pump 4, and the outlet pipe of the circulation pump 4 is connected to the three-way switching valve V1. It is configured to be selectively connected to the first heat recovery unit 6 or the traveling engine 11. The traveling engine 11 has two heat medium outlets 11a and 11b. And
The one heat medium outlet 11a is connected to a pipe between the viscous heater 3A and the second heat recovery unit via an on-off valve V2. The other heat medium outlet 11b is connected to the inlet side pipe of the circulation pump 4 via a parallel circuit of a radiator 13 and a bypass pipe 14 via a three-way switching valve type temperature sensing valve 12. When the temperature of the heat medium flowing into the temperature-sensitive valve 12 is low, the temperature-sensitive valve 12 connects the outlet pipe of the traveling engine 11 to the bypass pipe 14 and connects the heat medium to the temperature-sensitive valve 12. Is high, the outlet pipe of the traveling engine 11 is connected to the radiator 13.
It is configured to connect to the side.

Next, the structure of the variable capacity type viscous heater 3A which also serves as the clutch means will be described in detail with reference to FIG. In the following description, the front part means
3 indicates the left side, and the rear portion indicates the right side in FIG. The housing of the viscous heater 3A includes a front housing composed of a front housing main body 21 and a front plate 22, and a rear housing composed of a rear plate 23 and a rear housing main body 24. Then, the front housing body 21 and the front plate 2
2 and between the rear plate 23 and the rear housing main body 24, gaskets 25 and 26 are interposed, and are fastened by a plurality of through bolts 27 in a stacked state.

The heat generating chamber 28 is formed between a recess 22 a formed in the rear end face of the front plate 22 and a flat front end face of the rear plate 23. Further, the front plate 22
The boss 22b has a shaft sealing device 36 adjacent to the heat generating chamber 28.
Are provided, and a bearing device 37 is provided in the boss 21 a of the front housing body 21. A drive shaft 38 is rotatably supported via the shaft sealing device 36 and the bearing device 37. Also, at the rear end of the drive shaft 38,
A flat plate-shaped rotor 39 rotatable in the heat generating chamber 28 is fixed. A plurality of communication holes 39a penetrating back and forth are provided in the central region of the rotor 39.

At the front end face of the rear plate 23, a collecting recess 23a facing the central area of the heat generating chamber 28 is formed, and a supply groove extends from a lower outer peripheral position of the collecting concave 23a to a lower outer peripheral portion of the heat generating chamber 28. 23c is extended. In the rear plate 23, a collecting hole 23b is formed at an outer peripheral position of the collecting recess 23a, and a supply hole 23d is formed at an inner peripheral position of the supply groove 23c.

In the front housing, a front water jacket FW is formed between the inner surface of the front housing body 21 and the front end surface of the front plate 22 as a front heat radiating chamber adjacent to the heat generating chamber 28. On the other hand, in the rear housing, the gasket 26
A first rib 24a projecting in a ring shape is provided between the rear end face of the rear plate 23 and the inner surface of the rear housing body 24 on the outer peripheral side of the first rib 24a. A jacket RW is formed. Further, a control room CR is formed between the rear end surface of the rear plate 23 and the inner surface of the rear housing body 24 on the inner peripheral side of the first rib 24a.

A water inlet port 29 and a water outlet port (not shown) are formed adjacent to the rear surface of the rear housing body 24. Further, the front water jacket FW and the rear water jacket RW are communicated with each other by a plurality of fluid paths 30 (shown by dotted lines in FIG. 3) formed between the plurality of bolts 27. An electromagnetic valve 33 for opening and closing the collection hole 23b is provided in the rear housing body 24.
An electromagnetic valve 35 for opening and closing the supply hole 23d is provided, and is controlled by an external signal or an external operation (in this case, by a controller 40 described later). Solenoid valve 3
Reference numerals 3 and 35 function as adjusting means for adjusting the amount of silicone oil in the heat generating chamber 28. Reference numeral 31 denotes a surplus space provided above the heat generating chamber 28. The space between the wall surface of the heating chamber 28 and the outer surface of the rotor 39, the surplus space 31, and the control chamber CR are filled with a viscous fluid (in this case, silicone oil) having a volume equivalent to about 80% of the total volume. ing.

When the viscous heater 3A is heated, the solenoid valve 3 is controlled by a command from a controller 40, which will be described later.
3, 35 are controlled to close the collection hole 23b, and the supply hole 23
When d is opened and the drive shaft 38 is driven to rotate by the heating motor 2, the rotor 39 rotates in the heat generating chamber 28. Then, the silicon oil in the heat generating chamber 28 collects in the central region due to the Weissenberg effect, but this silicon oil is not recovered in the control chamber CR because the recovery hole 23b is closed. On the other hand, since the supply hole 23d is open, the silicon oil in the control chamber CR is supplied to the heat generation chamber 28. At this time, the silicon oil is supplied toward the outer peripheral side of the heat generating chamber 28 along the supply groove 23c, and is uniformly charged and supplied to the front and rear of the rotor 39 through a communication hole 39a formed in the rotor 39. Then, by the rotation of the rotor 39, the silicon oil is separated from the wall surface of the heat generation chamber 28
Heat is generated by shearing with the outer surface of the radiating chamber F.
A heat medium such as water circulating in the W and RW is heated and supplied to a heater core 5 a installed in the indoor heat exchange unit 5.

When the viscous heater 3A does not generate heat, the solenoid valves 33 and 35 are controlled by a command from a controller 40 to be described later to open the collection hole 23b and close the supply hole 23d. With this control, when the drive shaft 38 is rotationally driven by the heating motor 2, the supply oil 23d is closed, so that the silicon oil in the control chamber CR is not supplied into the heat generation chamber 28. On the other hand, the silicon oil in the heat generating chamber 28 is collected in the central region of the rotor 39 by the Weissenberg effect, and is recovered into the control chamber CR through the recovery hole 23b. For this reason, the silicon oil in the heat generating chamber 28 decreases, and the calorific value decreases to a negligible level.
Further, the load on the heating motor 2 also decreases.

FIG. 4 shows a control system of the heat medium circuit 20. The inside air temperature, the outside air temperature, the amount of solar radiation, and the temperature of the heat medium are input to the controller 40 as detection values of the inside air sensor 41, the outside air sensor 42, the solar radiation sensor 43, and the water temperature sensor 44, respectively. Further, the set temperature of the inside air is transmitted from the inside air temperature setting unit 45 to the controller 40. The controller 40 also includes a heater switch 46, the traveling engine 11, and the traveling motor 1.
ON / OFF information has been transmitted. The heating motor 2, the solenoid valves 33 and 35 for controlling the capacity of the viscous heater 3 </ b> A, the three-way switching valve V <b> 1, and the opening / closing valve V <b> 2 are controlled based on the information.

Next, the heating operation of the second embodiment configured as described above will be described. First, when the heater switch 46 is turned on, a heater switch ON signal is transmitted to the controller 40, and the heating motor 2 is driven by an operation command from the controller 40 based on this signal,
The solenoid valves 33 and 35 for controlling the capacity of the viscous heater 3A are controlled to close the collection hole 23b, open the supply hole 23d, and the viscous heater 3A enters a heat generating state. Also,
When the traveling engine 11 is stopped and the vehicle traveling motor 1 is traveling alone, an OFF signal of the traveling engine 11 is transmitted to the controller 40, and the three-way switching valve is instructed by the controller 40 based on this signal. V1
Is switched, the circulation pump 4 is connected to the first heat recovery unit 6, and the on-off valve V2 is closed. Therefore, the heat medium circulates as shown by the dotted arrow in the figure. That is, the viscous heater 3A generates heat, and the circulation pump 4 rotates. Then, through the circulation pump 4 and the three-way switching valve V1, the first heat recovery unit 6,
Second heat recovery unit 7, viscous heater 3A, heater core 5
a, The heat medium flows in the circulation circuit of the circulation pump 4, and heating is performed using heat generated by the viscous heater 3A, the traveling motor 1, and the heating motor 2 as a heat source, as in the first embodiment.

Next, when the driving engine is driven, a signal for turning on the driving engine is transmitted to the controller 40, and the three-way switching valve V1 is switched by an operation command from the controller 40 based on this signal. The circulation pump 4 is connected to the traveling engine 11, and the on-off valve V2 is opened. Therefore, the heat medium circulates as shown by the solid line arrows in the figure. That is, the circulation pump 4, the three-way switching valve V1,
Running engine 11, temperature-sensitive valve 12, radiator 13
And a bypass pipe 14, and a circuit circulating with the circulation pump 4 are formed. In addition, the circulation pump 4, the three-way switching valve V1, the traveling engine 11, the viscous heater 3A, the heater core 5a, and the heat medium of the circulation pump 4 A circuit is formed.

By forming the heat medium circuit in this way, a part of the heat medium heated by the traveling engine 11 is further heated by the viscous heater 3A from the heat medium outlet 11a and sent to the heater core 5a. The cabin air is heated.

Another part of the heat medium heated by the traveling engine 11 is connected to the heat medium outlet 11b and the temperature-sensitive valve 1
2, and circulated through the circulating pump 4 through a parallel circuit of the radiator 13 and the bypass pipe 14 to control the temperature of the heat medium. That is, when the traveling engine 11 is started, the temperature of the heat medium at the inlet of the temperature-sensitive valve 12 is low, so the temperature-sensitive valve 12 is connected to the bypass pipe 14 side. Therefore, the heat medium flowing out from the heat medium outlet 11b of the traveling engine 11 bypasses the radiator 13, and heat radiation from the radiator 13 is prevented. Therefore, the temperature of the heat medium increases. However, when the temperature of the heat medium rises with the lapse of time after the driving of the traveling engine 11, the temperature-sensitive valve 12 switches to the radiator 13, and the temperature-sensitive valve 12 is connected to the radiator 13. Therefore, the heat medium flowing out of the traveling engine 11 is flowed to the radiator 13 to radiate heat, and the heat medium is controlled so as not to exceed a predetermined temperature.

As described above, when the driving engine 11 is driven, when the vehicle driving motor 1 is driven and when the vehicle driving motor 1 is not driven,
In any case, heating is performed by the heat medium circuit formed as described above. Therefore, the vehicle driving motor 1
The heat generated by the vehicle driving motor 1 is not used.
This is because the calorific value of the traveling engine 11 having a larger calorific value than the calorific value of the driving engine 11 is preferentially used.

Next, when the vehicle running motor 1 is running alone and the heating operation is to be stopped, the heater switch 46 is turned off, and this OFF signal is transmitted to the controller 40. In response to an operation command from 40, the heating motor 2 is turned off, the viscous heater 3 and the circulation pump 4 are stopped, and the heating operation is stopped. The traveling engine 11
When the heating operation is stopped while the vehicle is traveling, the circulation pump 4 is also stopped because the circulation pump 4 also serves as the circulation pump for the heat medium as the cooling water for the traveling engine 11. I can't let it. Therefore,
In the present embodiment, when the heater switch 46 is turned off, this OFF signal is transmitted to the controller 40, and based on an operation command from the controller 40 based on this signal, the on-off valve V2 is closed and the viscous heater 3 is turned off.
By controlling the electromagnetic valves 33 and 35 of A, the recovery hole 23b is opened, the supply hole 23d is closed, and the viscous heater 3A is in a non-heating state, and the heating operation is substantially stopped.

According to the second embodiment constructed as described above, the heat medium is a non-combustion type heater, viscous heater 3A, traveling engine 11 or vehicle traveling motor 1,
Further, since the heating is performed by the heat generated by the heating motor 2, similarly to the first embodiment, the heating heat source device does not generate any combustion gas which causes air pollution. Further, heat generated by the traveling engine 11 or the vehicle traveling motor 1 and the heating motor 2 is not released to the atmosphere as it is, but is recovered and used as a heating heat source, thereby increasing heat efficiency. Further, the motors 1, 2 or the traveling engine 11 are also cooled, and the efficiency is improved. Further, the heating motor 2 is a motor 1 for driving the vehicle.
Independently, the heating motor 2 can have an appropriate capacity corresponding to the heating load, and can perform heating regardless of the driving of the traveling engine 11 and the vehicle traveling motor 1. In addition, even when the automobile is not running, heating can be efficiently performed by the heating motor 2. Further, since the heating motor 2 for driving the viscous heater is also used as a drive source for the pump 4 for circulating the heat medium, a dedicated device for circulating the heat medium is omitted. Therefore, compared to a case where a drive motor for driving the heat medium circulation pump 4 is separately provided, cost reduction, resource saving, space saving, and weight reduction can be achieved.

In the second embodiment, the three-way switching valve V1 and the on-off valve V2 are controlled by turning on / off the traveling engine 11, but this is controlled by turning on / off the water temperature sensor 44 for detecting the temperature of the heat medium. By controlling with / OFF, the waste heat of the traveling engine can be more effectively used. That is, when the traveling engine 11 is in the ON state and the heat medium temperature is sufficiently high to heat the passenger compartment, the position of the three-way switching valve V1 is changed by the operation command of the controller 40 based on the ON signal of the water temperature sensor 44. The outlet pipe of the circulation pump 4 is connected to the traveling engine 11 and
With the on-off valve V2 in the open position, the heat medium is circulated as indicated by the solid line arrow, and heating using waste heat of the traveling engine 11 is performed. In this case, the above-mentioned variable capacity viscous heater 3
The heaters 3A may be turned off by controlling the solenoid valves 33 and 35 of A. However, when the traveling engine 11 is stopped and the temperature of the heat medium becomes low, the position of the three-way switching valve V1 is circulated by the operation command of the controller 40 based on the OFF signal of the water temperature sensor 44. With the outlet pipe of the pump 4 connected to the second heat recovery unit 6 and the on-off valve V2 set to the closed position, the heating medium can be circulated as indicated by the dotted arrow to perform heating.

[0032]

Since the present invention is configured as described above, the following effects can be obtained. According to the first and second aspects of the present invention, there is no fear of air pollution since no combustion gas is generated from the heating heat source device. Further, since the heat generated from at least one of the vehicle driving motor and the heater driving motor is recovered and used as a heating heat source, the thermal efficiency is increased. Further, since the heating motor is independent of the vehicle traveling motor, heating can be efficiently performed by a motor having an appropriate capacity regardless of the traveling of the automobile.

According to the second aspect of the present invention, a dedicated motor for circulating the heat medium is omitted, and resource saving, space saving, weight reduction, and cost reduction can be achieved.

According to the third and fourth aspects of the present invention,
By using only one heat generator in a hybrid vehicle, the waste heat of the engine can be effectively used for heating at the same time as the waste heat of the traveling motor or the motor for driving the heat generator.
