DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for capturing oil smoke and the like generated while cooking from a range used in a kitchen and the like.
2. Background Information
Hitherto, the exhaust smoke purifier apparatus for capturing oil smoke generated while cooking from a range used in a kitchen and the like is assembled, as shown in FIG. 1. An exhaust smoke duct 6 is provided with one end being open as an inlet port 3. The inlet port is placed near a side part of a burner part 2 of a range 1. The other end of the duct is directed outdoors, penetrating through a wall 4 of a house, to make an exhaust port 5. A blower 7 is provided at the exhaust port 5. Furthermore, a detachable grease filter 8 is provided in the exhaust smoke duct 6 at the part near the inlet port 3, in order to isolate oil contained in the oil smoke. The solid arrows show the air flow.
In the above-mentioned assembly, when the blower 7 is driven, an air flow is generated which is in the direction from the inlet port 3 to the exhaust port 5, and oil smoke is drafted together with the air flow drafted from the inlet port 3 into the exhaust duct 6. On the other hand, the oil contained in the oil smoke adheres on the grease filter 8, and thereafter purified air is drafted outdoors from the exhaust port 5. Periodically, the grease filter 8 is removed from the exhaust duct 6 and washed by detergent or the like.
In the above-mentioned assembly, however, the oil adhering on the grease filter needs to be washed by removing the grease filter from the exhaust duct. A problem exists in that the environment is polluted from the washing and the like. Besides, odors generated from the cooking are exhausted outdoors in relatively large amounts in a relatively short period of time.
SUMMARY OF THE INVENTION
The present invention solves the above-mentioned conventional problems and effectively captures oil smoke inside the kitchen by integrally assembling a purifier, such as a catalyst and odor adsorbent in an exhaust duct, thereby sanitarily processing the oil and odor.
To solve the above-mentioned problems, a first embodiment of the present invention provides a reservoir part for temporarily holding oil smoke and the like, a purifier part for purifying the oil and an auxiliary blower. The auxiliary blower is set to have a smaller blow rate than the blow rate of an exhaust blower. The reservoir is integrally provided in an exhaust smoke duct whereof one end is open as an inlet port at a vicinity of a range and the other end is open as an exhaust port at a vicinity of the exhaust blower. The oil smoke, and the like, is captured by a greater air blow rate by the above-mentioned exhausting blower to hold it in the above-mentioned reservoir part. After cooking, the oil smoke and the like in the above-mentioned reservoir part is introduced into the purifier part by the above-mentioned auxiliary blower to purify it.
And, a second embodiment of the present invention provides a reservoir part for temporarily reserving oil smoke and the like and a purifier for purifying the oil. The reservoir is integrally provided in an exhaust smoke duct whereof one end is open as an inlet port at a vicinity of a range and the other end is open as an exhaust port at a vicinity of an exhaust blower. The exhaust blower is capable of two kinds of air blow rates. The oil smoke and the like during cooking is first captured by driving the above-mentioned exhausting blower at a greater air blow rate to reserve it in the above-mentioned reservoir part. After cooking, the oil smoke and the like in the above-mentioned reservoir part is introduced into the purifier part by driving the above-mentioned exhaust blower at a smaller air blow rate to purify it.
And furthermore, a third embodiment of the present invention provides a reservoir part for temporarily holding oil smoke and the like and a purifier for purifying the oil. The reservoir is integrally provided in an exhaust smoke duct whereof one end is open as an inlet port a
