Description of the Invention (/) [Technical Field] The present invention relates to a range hood suitable for gas stoves, electric stoves, and electromagnetic induction heating cooking heaters (IH heaters). [Prior Art] Conventionally, the range hood has various types such as flat type and boots type. The general system is equipped with an exhaust device behind the filter and an updraft between the front of the filter and the cover. The trapping space prevents the updraft from leaking into the room with the trapping space, removes the grease component contained in the updraft with a filter, and exhausts it to the outside with an exhaust device. In addition, there is also a type of range hood, in which a panel called a rectifying plate is arranged with a gap between the top plate of the cover body and the left and right side plates in front of the hood, and will be guided by the rectifying plate through the gap. The updraft is attracted by the exhaust device after increasing the wind speed, thereby preventing the updraft from leaking out of the cover. However, gas stoves and electric stoves that use natural gas, liquefied petroleum gas, etc. as fuel are generally popular as heating cooking appliances. However, as the demand for electromagnetic induction heating cooking heaters (IH heaters) increases, it is urgently needed. A range hood for an electromagnetic induction heating cooking heater is provided. In addition, the gas stove generates a strong updraft formed by the combustion gas containing carbon dioxide and, depending on the case, harmful substances such as carbon monoxide, in addition to steam from cooking pots and the like. Electric stoves do not produce as strong a gas flow as gas stoves during cooking. On the other hand, the electromagnetic induction heating cooking heater produces only 4 papers when cooking. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -------------- (Please read the precautions on the back before filling out this page) 1 ^ ·. 577967 A7 ___B7__ 5. Description of the invention (2) Generates weak updraft (including cooking odor including steam). ________I__I _ I · II (Please read the precautions on the back before filling out this page) Therefore, it is especially in the aforementioned electromagnetic induction heating cooking heater. Even if the past range hood is used, the updraft is weak, so it is effective. It is still not ideal to capture the updraft generated by cooking for exhaust. In addition to the problem of being unable to capture the updraft (including the cooking smell of steam) and polluting the kitchen ceiling, the temperature of the updraft is also low. There is a problem that the steam adheres to the cover body and the internal components and contaminates the cooking container and the meal under cooking. [Technical Problem to be Solved by the Invention] The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a range hood, which can improve the trapping efficiency of the updraft even if the heating cooking appliance is an electromagnetic induction heating type cooking heater. Another object of the present invention is to provide an extractor hood for taking in air into a control flow room for vortex ejection which is generated to increase the capture efficiency of the updraft. The updraft is not drawn in and does not hinder the updraft. . Still another object of the present invention is to provide an exhaust hood, which effectively utilizes an exhaust flow using an exhaust mechanism as a supply air source as a control flow, and ejects it toward a vortex generated in order to further improve the capture efficiency of the updraft. [Technical means to solve the problem] In order to achieve the above-mentioned technical means, the first item in the scope of patent application includes: a cover body; a vortex generator, which is generated in the cover body and is arranged above the heating cooking appliance, and guides the upward airflow downward. The Coanda effect is used to generate eddy currents; and the exhaust device is installed in the aforementioned cover 5 The paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 577967 A7 ___B7_ V. Invention Description (many) (Please read the precautions on the back before filling out this page) The back of the filter or the outside of the cover attracts the eddy current generated by the eddy current generator and exhausts it. Specifically, as in item 2 of the scope of patent application, the following configuration is adopted: The aforementioned eddy current generating system is composed of a rectifying plate, which is provided in a manner to ensure a gap between the left and right side plates of the cover body and the top plate. Above the heating cooking appliance, the rectifying plate includes a downward guide surface formed by a portion where an upward airflow strikes, and a curled surface connected to the guide surface and curved forward in an arc shape. As a result, the updraft that hits the vortex generator is directed downward and generates a vortex by the Coanda effect. The Coanda effect refers to the phenomenon of a fluid that generates a negative pressure when the updraft flowing along the wall surface is guided along the wall surface. With the strength of this vortex, a very weak updraft is drawn into it. Therefore, even if the thermal cooking appliance is an electromagnetic induction heating type cooking heater (IH heater), the weak updraft is not diffused outside the cover, and the updraft is quickly drawn in, trapped, and exhausted, thereby improving the capture. effectiveness. In addition, the third item of the patent application has a configuration in which a control flow ejection unit is provided below the vortex generator, and a control flow is ejected toward the tangential direction of the generated vortex to increase the intensity of the vortex. Thereby, it is very effective to stably generate a vortex of a desired strength, and to improve the trapping efficiency of the updraft. In addition, if the structure adopted in the fourth scope of the patent application is adopted, the control flow ejected by the aforementioned control flow ejection section is taken in from the room, and the air intake section is provided at a portion that does not face the updraft generated by cooking. . Specifically, if the structure adopted in item 7 of the scope of patent application is adopted, the cover closes the lower part of the front opening of the cover body, which is generally a right-angled triangle in side view. 6 This paper size applies the Chinese National Standard (CNS) A4 specification ( (210 X 297 mm) 577967 A7 ___B7____ One or five, description of the invention (f) on the upper part, a rectifier plate is provided with a gap from at least the left and right side plates of the cover body, and a filter is provided behind the rectifier plate, An exhaust device is provided at the back of the filter or outside the cover, so that the rectifying plate is formed with a downward guide surface formed by a portion where an upward airflow strikes, and a guide plate which is connected to the guide surface and bent forward in an arc shape. The curved surface is provided with a control flow ejection section on the cover, a control flow for enhancing the intensity of the vortex ejection obliquely upward from the bottom along the tangential direction that generates the vortex, and an indoor air intake section for the control flow ejected from the control flow ejection section. In the part where the aforementioned updraft does not face. In addition, it is preferable that the indoor air intake portion of the control flow ejection portion is provided on the side plates and the top plate which do not face the ascending air flow, and is provided on the top plate when the kitchen with a closet is adjacent on both sides. Thereby, the generated control vortex is ejected by the control flow ejection unit at the lower side, thereby stably generating a vortex of a desired strength and improving the upflow air collection efficiency. In addition, if the air intake method of the control flow ejection unit is an outdoor intake method through a connecting pipe, although it does not attract the updraft, not only the piping construction is troublesome, but the construction cost is increased, and the controllable indoor temperature is disturbed. . Therefore, the indoor circulation method was adopted in the patent application scope Nos. 4 and 7. If only the indoor air intake portion is provided, the updraft is attracted and the collection efficiency is reduced. Therefore, the indoor air intake portion of the control flow ejected from the control flow ejection portion is disposed at a portion where the updraft does not face, so that the updraft does not take in the air for the control flow, and does not impede the rising strength of the updraft. In addition, the structure adopted in item 5 of the scope of the patent application is that the intake section and the control flow ejection section communicate with each other through a passage. The passage has a cooling section for cooling the drive source of the exhaust device on the way.

Description of the invention (3) The indoor air is used to cool the driving source of the exhaust device. ----------------- (Please read the precautions on the back before filling this page) In addition, the structure adopted in item 6 of the scope of patent application is the aforementioned control of the ejection section. It is arranged on the left and right along the illuminating member. The illuminating member is arranged at the center in the width direction of the cover below the fairing plate, and the illumination-side portions of the two control flow ejection sections are arranged in an upwardly inclined manner so as to intersect while extending upward.俾 The vortex generated by the vortex generator is uniformly generated over the entire width of the vortex generator. In the range hood, a lighting member is provided at the center in the width direction in order to view cooking conditions and the like. When it is installed in the center of the cover, if it is provided on the top plate side of the cover, the illuminating member closes the gap between the rectifier plate and the top plate, and a good exhausting result cannot be expected. Therefore, in item 6 of the scope of the patent application, the illuminating member is provided at the center in the width direction of the cover below the fairing plate, and the control flow ejection portion is arranged right and left through the illuminating member. As a result, when only the front view of the control flow is ejected upward, a vortex cannot be stably generated in the area portion directly above the luminaire. Therefore, by adopting a configuration in which the control flow also acts on the area directly above the luminaire, the control flow can be uniformly applied to the entire range in the width direction of the vortex generator, and a vortex of a desired intensity can be stably generated throughout the entire width of the vortex generator. In addition, as for the items 8 and 9 of the scope of patent application, the control flow can also adopt an exhaust flow using an exhaust device as a supply air source. This eliminates the need to control the supply air source for streaming applications. In addition, in order to effectively use the exhaust gas flow as a control flow, it is preferable that the control flow is supplied through a deodorizing mechanism (applications for patent scope Nos. 10 and 11) ° {This is the deodorizing mechanism, according to the heating cooking appliance Category, optionally using effective adsorption removal, decomposition removal from gas furnace, electric furnace, electromagnetic one-_ 8 P-squared scale applicable to China National Standard (CNS) A4 specifications (21〇χ 297 public issued one) 577967 A7 _ B7__ V. Description of the invention (Hand) ------------- Installation --- (Please read the precautions on the back before filling out this page) The proper composition of gas produced by induction heating cooking heater mechanism. In addition, the deodorizing mechanism is a replaceable person, or a person who can freely attach and detach a handler. In addition, it is possible to control the wind speed of the aforementioned control flow regardless of the exhaust volume of the exhaust device (items 12 and 13 of the scope of patent application). As mentioned above, in order to obtain the vortex generated by the Coanda effect with the downwardly directed upward airflow, it is preferable to use a control flow at a predetermined wind speed for assistance. If the exhaust amount of the exhaust device is reduced, the speed of the discharge wind of the control flow is also automatically reduced, so that it is impossible to supply the required control flow in order to stably generate the vortex. On the other hand, if the exhaust volume of the exhaust device increases, the speed of the discharge wind of the control flow increases, which prevents the rising of the updraft from spreading to the side of the cover, thereby preventing the steady generation of the vortex. Therefore, it does not restrict the exhaust volume of the exhaust device (switching between "strong", "medium", and "weak"), does not blow up the updraft, and during operation, it is always supplied at the desired wind speed that stably generates vortices. Control flow. In addition, it is preferable that the wind speed of the aforementioned control flow is 2 to 3 m / sec (items 14 and 15 of the scope of patent application). If it is less than 2m / seC, the eddy current generated by the Coanda effect is weak. If it exceeds 3m / sec, a turbulent flow that prevents the eddy current from being generated is generated.

The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 577967 A7 ______B7_____ 5. Description of the invention (Δ) the bottom part behind a2. The left and right edges of the support plate a3a are in contact with the inner surfaces of the left and right side plates alb and alb of the cover body a1. _ The rectifying plate a2 is placed in front of the filter a3 as shown in FIG. 2 so as to be accommodated in the cover a1, so that the upper edge and the side portion a3a-1 of the upper side of the supporting plate a3a, And the suction gap G is formed between the left and right edges and the left and right side plates alb and alb of the cover body a1. Further, the rectifying plate a2 supports a portion near the upper end to the support plate a3a by an appropriate mechanism, and mounts a lower end portion on the lower end portion of the support plate a3a. An exhaust device a4 is housed in the space behind the support plate a3a. The exhaust device a4 is composed of a Sirocco fan that exhausts the house. The exhaust device a4 and the cover a5 are located between the exhaust device a4 and the cover a5.

Description of the invention (?) It is inclined to form an opening so that it follows the cover a5 jets airflow obliquely upward. Thereby, the airflow from the control flow ejection part 21 forms a control flow F for enhancing the strength of the vortex, which will be sprayed obliquely upward toward the tangential direction of the vortex Q, which will be described later. In this embodiment, the curvature of the curled surface a2b is set to Φ90ηιηι The continuous curvature of the lowermost edge of the curled surface a2b and the lower edge of the support plate a3a is set to Φ10 mm. The guide surface a2a has a shape that can be guided downward, such as a substantially horizontal shape, a gently inclined shape, and a gently curved shape. The exhaust hood configured as described above makes the cooking odor (upstream air) B including the steam generated during cooking hit the guide surface a2a of the rectifying plate a2, guides it downward, and passes through the guide surface a2a. When the curled surface a2b connected and curved forward is further guided, a negative pressure is generated, thereby generating a vortex Q. From the side opposite to the updraft B, the control flow ejection portion 21 discharges the control flow F for vortex strength enhancement into the vortex Q obliquely upward along the upper part of the cover a5 and toward the tangential direction of the vortex Q, thereby making it possible to more stably A vortex Q (see FIG. 2, FIG. 3, and FIG. 4) of a desired intensity rapidly taken into the updraft B is generated. This vortex Q is a left-right gap secured between the left and right side plates alb and alb of the cover body a and the fairing plate a2. S and S are shared and sucked by the exhaust device a4 through the filter a3 and discharged outside the house (refer to FIGS. 3 and 4). Thereby, the updraft B can be efficiently collected and exhausted without being diffused outside the cover body a1. In addition, when colliding with the aforementioned guide surface a2a, the paper size of this paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) Binding ·-577967 A7- -. _B7____ 5.

The partition walls 29 and 29 on both sides of the waste liquid container 2 extend to the upper end of the control flow path 9, and the upper end open portion is closed, and the control flow is supplied only to both sides of the lighting fixture 1 and the waste liquid container 2. . In addition, the control flow ejection portions 21 and 21 are formed at the two sides of the illuminating member 1 in a slit-like shape at intervals along the width direction of the cover body 1 so as to form an opening on the upper side of the curved cover member a5. The cover a5 sprays airflow obliquely upward, and forms an opening inclined upward as viewed from the front so as to intersect while extending the side portion of the illuminator 1 upward (specifically, the left and right half). The upward air flow rising in front of the luminaire 1 is well guided to the central portion of the fairing plate a2, so that eddy currents are uniformly generated along the entire width of the fairing plate a2. The exhaust hood constituted above guides the cooking odor including the steam generated during cooking (including the upward airflow of steam) to the guide surface a2a of the fairing plate a2 and guides it downward, and is connected to the guide surface a2a and directed to the When the curled surface a2b curved forward is further guided, a negative pressure is generated, thereby generating a vortex Q, and the vortex Q is injected into the vortex Q with the exhaust flow as a control flow F for vortex strength enhancement. The exhaust flow is an exhaust flow that uses the drive source a4a of the exhaust device a4 as the air supply source without hindering the rising strength of the upward flow B. The exhaust flow flows from the control flow ejection portions 21 and 21 toward the tangent line of the vortex Q. The direction is obliquely upward from the curved cover a5 to spray out 'by this', it can more stably generate the vortex of the desired strength that quickly takes in the updraft B. 23 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 577967 A7 _____ Β7 V. Description of the invention (> /) -------------- Install --- (Please read the precautions on the back before filling this page) Then, do n’t The exhaust gas flow for the control flow is the same as the control flow F. After over 100 institutions deodorant, circulate indoors. Under the same conditions as the previous embodiment, experimental results show that in the cover a1 of this size, the control flow F ejected from the control flow ejection sections 21 and 21 at a wind speed of 2 m / sec enables the exhaust air flow B to be discharged. The highest gas efficiency. Of course, the range hood of the present invention can be similarly applied to heating cooking appliances such as a gas stove and an electric stove. In addition, although the present embodiment discloses a configuration in which an exhaust flow which is not a control flow is circulated indoors, the present invention also includes a configuration in which an exhaust flow which is not a control flow is discharged to the outside. Line · As mentioned above, in the present invention, the vortex generating body that generates the vortex by the Coanda effect is guided downwardly and the vortex generating body is installed behind or outside the cover of the cover body or the cover body. The air device attracts and discharges the eddy current generated by the eddy current generating body. Therefore, even if the electromagnetic induction heating cooking heater is used as a heating cooking device under the action of the eddy current, the eddy current can be raised very weakly. The airflow (including the cooking odor of the airflow) does not diffuse outside the cover, and it is quickly attracted, trapped, and exhausted to ensure high capture efficiency. In addition, since the updraft is accelerated and exhausted by the vortex, the contact time between the vortex generator and the filter behind it is also shortened, and the water vapor peculiar to the electromagnetic induction heating cooking heater is prevented in real time, and Suppresses dripping during cooking and contaminates the cooking container or cooking. In addition, a rectifier plate is provided above the heating device, and the air is sucked and exhausted by the exhaust device behind the rectifier plate through the gap between the rectifier plate and the cover body. 24 This paper applies the Chinese National Standard (CNS) A4 specification. (210 X 297 mm) 577967 A7 ___B7___ 5. Application for an exhaust hood of the invention description (7 >), in which the aforementioned rectifying plate is formed into a shape that will guide the upward airflow downward and generate a vortex with the Coanda effect. The second scope of the patent can effectively use the rectifier to generate eddy currents without complicating the structure and causing high costs. '' In addition, if the range hood of the third patent application scope is provided below the vortex generator, the control ejection portion for ejecting the vortex of the control flow for enhancing the eddy current intensity toward the tangential direction can be further increased. Stable; t also generates eddy currents, and can increase the intensity of eddy currents, so that the capture efficiency of the updraft is further improved, which is very suitable for the occasion where the electromagnetic induction heating cooking heater that generates a weak updraft is used as a heating cooking appliance. In addition, if the structure of the range hood of item 7 of the patent application is applied, the cover closes the lower part of the front opening portion of the cover body, which is a substantially right triangle in side view, in the upper half, on at least the left and right side plates with the cover body. A rectifying plate is provided with a gap therebetween, and a filter is provided behind the rectifying plate, and an exhaust device is provided behind the filter or outside the cover, so that the rectifying plate is formed to include a portion where an upward airflow strikes A downward guide surface and a curled surface connected to the guide surface and curved forward in a circular arc shape; a control flow ejection unit is provided on the cover member, and a control for enhancing the intensity of the vortex flow obliquely upward toward the tangential direction where the vortex is generated; Convective vortexes are emitted from the obliquely downward control flow. 'Vortex currents of constant intensity that are engulfed by updrafts are often generated, which greatly improves the collection efficiency, and the rise of updrafts is not affected by this control flow. The cover spreads to the outside and contaminates the kitchen ceiling. In addition, as described in item 4 of the scope of patent application, since the 25 I scale of the control flow is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 public love) (Please read the precautions on the back before filling this page ) Binding ·-577967 A7 _B7___ V. Description of the invention (> 3) The take-in section is set at the part where the updraft does not face, so even if the electromagnetic induction heating cooking heater is used as a heating cooking appliance, the strength can still be enhanced by It can stably generate vortices. Under the action of the vortex, even if it is a very weak updraft (including the cooking odor of steam), it can be quickly gathered so that it does not spread out of the cover. Exhaust after capture, to ensure high capture efficiency, use clean indoor air to increase its eddy current, as described in item 5 of the scope of patent application, if there is an exhaust device on the way The path of the cooling section where the drive source cools, and the intake section and the control flow ejection section are connected. It is not necessary to deal with the prevention measures for the reduction in durability caused by the heating of the drive source of the exhaust device through a dedicated mechanism. In order to prevent the heating of the driving source, the structure can be simplified and the cost can be reduced. Also, as in the sixth item of the scope of the patent application, the control flow ejection section is arranged left and right through the lighting member, which is arranged below the rectifying plate. In the center of the width direction of the cover body, when the illumination side portions of the two control flow ejection sections are extended upwards in the past, when the front view is inclined upward, regardless of the installation of the illuminator, the Control flow is applied uniformly over the entire width direction to form a vortex of a desired strength stably, which further enhances the intensity of the vortex, and can ensure high capture efficiency. In addition, as in items 8 and 9 of the scope of patent application, the control flow is effectively used When the exhaust device is used as the exhaust flow of the air supply source, it is not necessary to install a dedicated blower for blowing the control flow, which can greatly reduce the cost of the equipment. Like the 10th and 11th in the scope of patent application, the control flow contains The gas is removed by the deodorizing mechanism, so the gas containing cooking odors has not been applied to the Chinese standard 26 (CNS) A4.
