ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a kitchen range hood having a peripheral oil collection device so as to collect all the oil drops possibly flowing from the casing of the kitchen range hood.
BACKGROUND OF THE INVENTION
A conventional kitchen range hood for sucking oily smoke generally includes a casing in which a motor with fans is installed and a pipe is connected to a chamber communicating with the fans so as to send the smoke from the interior of kitchen via the pipe. Nevertheless, the smoke includes a lot of oil particles and cannot to be completely sucked by the fans. To prevent some of the oil particles from adhering on the inner periphery of the casing and dropping directly to the cook top or kitchen counter, the oil collection device is therefore connected to the lower edge of the casing and is expected to collect the oil particles that remains on the casing. The conventional oil collection device is connected to a lowest edge of the casing because the designers believe that the oil particles will flow downward on the casing and finally drop into the oil collection device. However, because of viscosity of the oil particles, some of them adhered on the casing and drop at a position higher than the position where the oil collection device is connected.
The present invention intends to provide a oil collection device for a kitchen range hood wherein the oil collection device is connected along a periphery of the casing so that all the oil particles will be finally collected in the oil collection device.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a kitchen range hood comprising a quarter-sphere casing having an open rear end and an open bottom, a rear plate engaged with the open rear end of the casing. A flange extends radially outward from a lower edge of the casing. A first oil collection device is engaged with the flange and has an opening facing an interior of the casing. A second oil collection device is engaged with a lower edge of the rear plate. A support plate has a first end engaged with the rear plate and a second end of the support plate is located above the opening of the first oil collection device. A ventilation device is supported on the support plate.
The primary object of the present invention is to provide a kitchen range hood the has oil collection devices connected along a periphery of the casing of the range hood so as to collect all the oil particles that are not sucked by the ventilation device in the range hood.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
