Abstract

PURPOSE:To improve the effectiveness of smoke evacuation and ventilation, and improve the clean environment of kitchen by the suction of air from an upper side, a back side and nearby of a fire of cooking utensils. CONSTITUTION:An oil smoke floating at an upper side and back side of cooking utensils as shown by arrow marks (a), (b) is sucked up via filters 8, 12 by the driving of a fan 3. Thereby, the oil smoke located in the vicinity of the cooking utensils is immediately and steadily sucked up and gathered at the upper side and nearby the location where the smoke is produced, accordingly, the ventilation effectiveness and the cleanness of kitchen environment can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood that effectively exhausts oil smoke, etc. during cooking. It has a structure as shown in Fig. 1, and 1o1 is a range hood main body that incorporates a fan device 102 and a filter 103. When the fan device 102 is energized and driven in the above configuration, the air flow shown by the dotted arrow A is generated. is generated, and oil smoke, etc. during cooking is sucked in from the suction port 104 located at the bottom of the range hood main body 101. With such a configuration, wind is prevented from flowing between the place where oily smoke is generated during cooking and the above-mentioned suction port 104.
If it blows, it may not be able to be collected.Furthermore, it is necessary to increase the capacity of the fan device 102, resulting in increased power consumption, increased noise, etc. Furthermore, the oil smoke from cooking was not sufficiently exhausted, staining equipment around the range and spoiling the aesthetics of the kitchen.

Purpose of the Invention The present invention solves the above-mentioned drawbacks of the conventional range hood.It is an object of the present invention to not only suck oily smoke etc. from above the cooking device of the conventional range hood, but also to draw air from the rear of the cooking device in the immediate vicinity of the place where the oily smoke is generated. It provides a range hood.

Structure of the Invention According to the present invention, openings are provided for exhausting air from above and from the rear of the cooking appliance, thereby providing effective ventilation from two directions, and preventing oil smoke from scattering from the cooking stove in the kitchen.

DESCRIPTION OF THE EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on FIGS. and the first suction port 6 at the bottom. It is installed so that the second suction 1''6 is located. T is an auxiliary hood that is provided with a first filter 8 and protrudes forward from the range hood main body 1 to enhance the oil smoke collection effect, and is larger in both depth and width than the range hood main body 1. An upper surface opening 9 is provided, and the first suction port 5 of the hood body 1 is aligned with the opening to constitute a first exhaust passage a. On the other hand, 10 is a box for exhausting the fire source, which is located at the part where the oil smoke is generated at the rear of the cooker.
There is an intake port 11 that takes in oil smoke, exhaust gas, etc., and a second intake port behind it.
The hood body 1 is provided with a filter 12 that stands up vertically and has a second upper surface opening 13 aligned with the second suction port 6 of the hood body 1.

It constitutes a second exhaust passage.

In the above configuration, when the fan device 3 is energized and driven, exhaust operations a and b shown by solid line arrows in FIG. 2 occur. The movement of oil smoke and exhaust gas generated during cooking is first collected and suctioned through the intake port 11 located at the rear of the cooking device in the exhaust operation b. In addition, oil smoke and exhaust gas that are not sucked in by the intake air 11 are also collected and sucked through the auxiliary hoods 7 located on three sides of the cooker as shown in FIG. Due to the suction force sucking air from the rear of the cooker in the two-way air loss operation described above, oil smoke and exhaust gas are out of the collection effect range of the auxiliary hood 7 even if affected by external wind, etc., so conventional cookers It has a higher collection effect than a range hood that has a suction port only above.

Effects of the Invention As described above, the range hood of the present invention has a built-in fan device and a first fan device at the bottom. [1 part] was provided between the second suction port and the first upper surface in accordance with the first suction port 1. an auxiliary hood constituting a first exhaust passage including a first filter; and a second exhaust passage including a second filter and having a second upper surface opening aligned with the second suction port. The fire source exhaust box and Karasha that make up the
Since the above-mentioned exhaust operation from two directions is configured, oil smoke and exhaust gas during cooking can be effectively ventilated from two directions, preventing oil smoke from scattering around the kitchen cooker, and creating a clean kitchen environment. Its practical effects are significant.
