What also can expect is, the fan motor housing can not be the position of above-mentioned discussion but forms in other position with heating container.Heating container only needs be fit to keep cleaning fluid, from the fan motor heat absorption with transfer heat to cleaning fluid.

What should expect is that described pump can be by programmable system control or hand-guided automatically.Preferably, pump 32 can start when motor 15 energisings.Like this, the constant wash liquid stream heating container of will flowing through absorbs heat energy from conduction surfaces.This not only can heated wash liquid, and cooling motor (heat comes from motor) on the contrary.The cleaning fluid of more efficiently heating, the temperature during by the reduction motor operations has also been brought to prolong the motor benefit in service life when removing grease except being provided at.

The temperature of the cleaning fluid of dress in intermediate receptacle 30 also can be fit to determine.Pump 32 also can be equipped with stop valve, in case so that the cleaning fluid in the intermediate receptacle 30 arrives predetermined temperature, pump 32 cuts out.In case temperature drops to design temperature, pump 32 restarts.By reducing working time length, this set helps to prolong the service life of pump 32.Be used for fluid also can be started automatically from the pump 28 that middle container 30 guides to fluid delivery system, for example after specified number of days or after smoke exhaust ventilator uses, or start-up by hand.

What should expect is, can have one or more intermediate receptacle 30 and corresponding pump to use (heating container and motor sub-assembly are arranged) with two heating containers and the motor sub-assembly of smoke exhaust ventilator in each chamber of motor shell.

The increase of heating container provides additional cleaning fluid storage area.When in conjunction with the memory capacity of intermediate receptacle 30, to compare with the prior art design that only has the soda liquor container that is positioned at the motor shell outside, heating container can make smoke exhaust ventilator that the cleaning fluid of more volume is housed.In addition, heating container can only utilize the existing space in the hood body, so the overall dimension of smoke exhaust ventilator needn't increase for holding said container.

Be contemplated that other materials can be used to form the heating container of non-integral such as heat resistant plastice.Though the cleaning fluid of the use of plastics in can be from the motor to the heating container transmits identical heat, uses more convenient and with low cost.

Though it will be understood by those skilled in the art that and describe preferred and alternate embodiment in detail, can make specific change, and not break away from principle of the present invention.
