A thermal demand priority type cogeneration system, is made operative for obtaining power output without thermal demand. When the temperature in a hot water tankis low, a heat request is output from a heat request generatorand thereby an engineis driven. When the temperature T higher than a predetermined temperature T, a first water supply instructing unitopens a valveand supplies water to the tankto decrease the water temperature T. When the water temperature goes down, thermal demand is generated, the engineis driven according to the heat request. So as to generate thermal demand, a discharge valvemay be opened when the water temperature T is at the predetermined temperature or higher. A second water supply instructing unitopens the valvewhen reserved water level in the tankgoes down. When the valveis opened, water is supplied and the water temperature goes down and thermal demand is generated. At a power failure of a commercial electric power system, thermal demand is generated forcibly.

Cogeneration apparatus

In a cogeneration system having a first power plant connected to an AC power feed line between a power network and an electrical load and a first internal combustion engine for driving the first power plant such that exhaust heat of the first engine is supplied to a thermal load, power supply from the first power plant to the power network is interrupted by turning off a switch installed in the feed line, when outage of the power network is detected and a second power plant is operated, such that outputs of the first and second power plants are supplied to the electrical load. With this, it becomes possible to respond to a commercial power network outage for preventing reverse flow of the power output by the cogeneration system into the power network and supplying as much electric power as possible to the electrical load.

Cogeneration system with first and second power plants

In a cogeneration system having a power plant that includes a generator and an internal combustion engine for driving the generator such that exhaust heat of the engine is supplied to a thermal load, there are provided a battery, a controller that controls operation of the thermal load, a main switch disposed to be operable by an operator, a microprocessor that controls operation of the power plant when the main switch is turned on by the operator, and an external terminal adapted to transmit an activation signal to the controller upon manipulation by the operator when the main switch is kept off. In the system, the microprocessor is operated by power supplied from the battery in response to the activation signal so as to activate the power plant. With this, even when the operator stays at a place away from the main switch, the power plant can be activated to supply power to electrical loads.

An alignment operating member is mounted to the operating unit for rolling and vertically moving the snow-removing implement. The alignment operating member is disposed on one of opposite sides of a widthwise central line of the machine body. A return operating member is mounted to the operating unit for automatically returning the snow-removing implement to a predetermined reference position. The return operating member is disposed proximate to the alignment operating member at a position closer to the widthwise central line of the machine body than the alignment operating member and further towards the rear part of the machine body than the alignment operating member.

Self-propelled snow remover

A cogeneration system comprising a generator connected to an AC power feed line between a power network and an electrical load and an internal combustion engine for driving the generator and for supplying its exhaust heat to a thermal load. The power supply from the generator to the power network is interrupted by turning off a switch installed in the feed line when an outage of the power network is detected. A battery for storing DC power is connected to an inverter circuit to invert the DC power to AC power, such that the inverted AC power of the battery and the output of the generator are supplied to the electrical load, thereby enabling the system to respond to a power network outage and preventing reverse flow of the power output by the cogeneration system into the power network while supplying as much electric power as possible to the electrical load.

In an engine drive washing machine, a discharge switchis provided in a jet gun. When the switchis turned off, an engineis stopped. When the switchis turned on, the engineis started up to drive a pump. When an outlet pressure of the pumpis not lower than a predetermined value, a water-discharge valve in the gunis opened to cause the water to be discharged. When the switchis not turned off for a long time, the engineis stopped. When an operator takes up the gunto start the operation, the engineis started up. The engine-drive type of washing machine is provided with a batteryfor a starter motor, and the batteryis charged by a generator function of a starter-motor generatorduring the operation of the engine

Engine driven working machine

In a cogeneration system having a generator unit that generates DC power, an internal combustion engine for driving the generator unit, a battery that stores DC power for starting the engine, and an inverter that inverts the DC power generated by the generator unit to AC power, there are provided a solar unit that generates DC power by converting radiant energy of sunlight into electrical energy and a DC/DC converter that boosts the DC power stored in the battery, such that one of the battery and the solar unit is connected to the inverter through the DC/DC converter, thereby enabling them to share the DC/DC converter and thus to make the structure simple.

A self-propelled snow remover has a machine body, travel units mounted on the machine body to undergo turning movement and linear movement, and at least one steering member mounted to the machine body and operable to turn the travel units. A snow-removing implement is mounted to the machine body to undergo lifting, lowering and rolling movements relative to the machine body. A lift drive mechanism lifts and lowers the snow-removing implement. A control unit controls the lift drive mechanism by issuing a lift drive instruction to the lift drive mechanism so as to automatically lift the snow-removing implement when a steering condition in which the steering member is turned is determined to be satisfied, and by issuing a lowering drive instruction to the lift drive mechanism so as to automatically lower the snow-removing implement when the steering condition is determined to be no longer satisfied.

A self-propelled work machine, in which the load of the work unit increases according to an increase in the travel speed. The self-propelled work machine includes electric motors for driving the travel units, an engine for driving the work unit, a work drive instruction unit for instructing the work unit to turn on, and a control unit for controlling the electric motors. The control unit reduces the actual speed of the electric motors by using PID control so that the actual rotational speed of the engine returns to a reference rotational speed when the actual rotational speed of the engine falls below the reference rotational speed in the state in which the work unit is turned on by the work drive instruction unit. The reference rotational speed is a reference value used when the work unit is driven by the engine.
