Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention is applicable to household and commercial fish grills, yakitori grills, and smoker grills. The present invention relates to a deodorizing device that is attached to a cooking utensil or the like and removes malodorous components from smoke generated during cooking to make it odorless.

(Technical background of the invention and its problems) Generally, when fish and meat are cooked by grilling or smoking, these cooking utensils emit water vapor and carbon dioxide gas along with the heating aroma peculiar to the food. At first, smoke containing a strong pungent flammable odor component, which is a complex mixture of fine oil droplets and various organic substances, as well as gases such as hydrogen sulfide and ammonia, is generated, and this smoke is emitted from the ceiling and It may adhere to walls and contaminate indoor walls, and may have a particularly negative effect on the human body.

The most typical means to prevent this is to install a ventilation fan or install a smoke exhaust duct near the area where cooking utensils are used. It is not always possible to exhaust the entire amount of smelly smoke generated from the room to the outside, and a considerable amount still remains indoors, and furthermore, the smelly smoke is not purified.
Since the odor is emitted into the air, it is not a fundamental solution and it significantly deteriorates the surrounding living environment, so there has been a strong desire to develop a deodorizing device that can reliably prevent this.

(Purpose of the Invention) The present inventor has conducted various research and experiments on this point for many years, and based on his rich past experience, the direct combustion method using an afterburner is the most effective for purifying g% gas. This is a book that successfully solves all of the above-mentioned considerations at once, and its main purpose is to attach a combustion device with a relatively small and compact structure to a heating cooker. , most of the harmful gases such as hydrogen sulfide and ammonia, as well as combustible odor components that cause bad odors.
An object of the present invention is to provide an innovative deodorizing device that can be completely combusted and rendered odorless and harmless.

(Summary of the invention) The outline of the structure of the device of the present invention for achieving the above object is as follows.
A combustion tube with an exhaust port at the top and a donut-shaped burner at the bottom is installed inside the vessel with an air intake and a smoke inlet at the bottom, and a four-tube conduit leading from the smoke inlet to the center of the burner. The inside of the combustion tube is equipped with an electric fan and a damper, and an ignition device and a fire power adjustment device are attached to the base side of the burner. It is characterized by the arrangement of a cone-shaped flame guide plate, a circular perforated incandescent plate pattern, and a shielding plate.

(Embodiments of the Invention) Hereinafter, the structure and operation of the deodorizing device according to the present invention will be specifically explained with reference to the drawings of the embodiments. It is a box-like vessel formed into a rectangular shape.The interior of the vessel (1) is divided into two upper and lower chambers by a partition wall (2).Of these, the upper chamber (/a)
A cylindrical combustion tube (3), which is the main body of the deodorizing device (M), is installed in the center of the cylinder.The combustion tube (3) has a circular exhaust port r4) at the upper end and a donut at the lower end. type burner (
5), and the interior C2 of the combustion tube (3) has a truncated cone-shaped flame guide plate (6) and two perforated incandescent plates (7a) (7b), which are arranged from the bottom to the top. of shielding plates (ga)
(W) will be constructed in order. In addition, the lower chamber (10) 2 is provided with an air intake port (9) and a smoke intake port (I()) at the bottom, and the smoke intake port 00 is also connected to the pipe line of the smoke guide pipe 0υ leading to the center of the burner (5). , an electric fan Q2 driven by a motor (/2) and an intake air regulating damper αJ are interposed, and a fuel supply pipe (1t9 In this embodiment, a small portable LP gas cylinder (/4a) is used to supply fuel.

Since the deodorizing device I'l according to the present invention has the above-mentioned hs structure C2, the deodorizing device I'l is installed on the top of the heating cooking appliance σ() such as a fish fryer, yakitori cooker, smoker, etc. as shown in Fig. 2. (After installing the VD and connecting it so that the smelly smoke inside the heating cooking appliance (H) can be inhaled from the smoke inlet, I took a picture of the igniter Q4J (/4
Turn ta) to supply fuel to burner a9 and blow out fuel from burner Q9).
) wait for the perforated incandescent plate (7aX7b) to become red hot, adjust the damper (2) while driving the electric fan @, and heat the inside of the heating cooking appliance (H) from the smoke inlet αQ through the flue pipe θυ. When the odor smoke is introduced into the center of the burner mark, the flammable odor components in the odor smoke are first enveloped by the burner flame within the truncated cone-shaped flame guide plate (6) and are strongly raised while undergoing primary combustion. A red-hot perforated red-hot plate (
7a) (7'b), which causes secondary firing and burns to the remaining flammable malodorous components, then the shielding plate (!ra) (
fo ) and is guided to the inner circumferential surface of the combustion tube (3) until it is discharged to the outside from the upper exhaust port (4).
Not only the flammable malodorous components contained in the smoke, but also hydrogen sulfide and ammonia, which are harmful to the human body, are oxidized and decomposed, making it completely odorless and safe. , only the burnt gas will be discharged upward from the deodorizer a (Vo). By simply attaching this to the top of existing cooking utensils such as fish fryers, yakitori cookers, and smokers, you can eliminate flammable odor components in the smoke emitted from the cooking utensils, as well as hydrogen sulfide and ammonia that are harmful to the human body. Since other components can be almost completely combusted and rendered odorless and harmless, it exhibits excellent usage effects that can keep the surrounding living environment comfortable and hygienic for both home and commercial use.
