Warm-up system and warm-up method for in-vehicle power train
First Claim
1. A warm-up system for a vehicle that pre-heats a vehicle power train by transferring heat from a heat source to an engine cooling water circulation circuit, comprising:
- a heat source circuit that circulates heat from a medium in a household heat source; and
a connector that;
connects the engine cooling water circulation circuit and the heat source circuit prior to start-up of the vehicle power train such that heat from the heat source circuit is transferred to the engine cooling water circulation circuit, anddisconnects the engine cooling water circulation circuit and the heat source circuit after the heat is transferred to the engine cooling water circulation circuit,wherein the connector includes;
a vehicle side jack on a first branch pipe that bifurcates from the engine cooling water circulation circuit, anda residence side plug on a second branch pipe that bifurcates from a residential hot water circuit,wherein the heat source circuit transfers heat through the connector as a flow of the medium to the engine cooling water circulation circuit.

Abstract
In a warm-up system that pre-warms up of an engine (E) by transferring heat from a heat source to an engine cooling water circulation circuit (1) of a vehicle, a residential hot water circuit (2) that uses a household heat source is provided as the heat source, and a one-touch connector (3) is provided in the engine cooling water circulation circuit (1) and the residential hot water circuit (2). The one-touch connector (3) connects the two circuits (1, 2) prior to start-up of the engine (E) such that heat is transferred to the engine cooling water circulation circuit (1), and disconnects the two circuits (1, 2) following heat transfer in preparation for start-up of the engine (E).

19. A warm-up method for a vehicle power train, which pre-heats the vehicle power train by transferring heat from a heat source to an engine cooling water circulation circuit, that includes a heat source circuit, that circulates heat from a medium in a household heat source, and a connector in the engine cooling water circulation circuit and the heat source circuit configured to connect and disconnect the engine cooling water circulation circuit and the heat source circuit, the warm-up method comprising:
-
connecting the engine cooling water circulation circuit to the heat source circuit the connector prior to start-up of the vehicle power train; transferring heat from the heat source circuit to the engine cooling water circulation circuit through the connector by the flow of the medium when the engine cooling water circulation circuit and the heat source circuit are connected; and disconnecting the engine cooling water circulation circuit from the heat source circuit after the heat is transferred to side the engine cooling water circulation circuit.
