Description

Smoke exhaust device for grilling meat

[0001] The present invention relates to a smoke exhaust device for a meat grill, which not only prevents an overload on a motor provided in an exhaust duct when multiple meat grills are connected to a single exhaust duct and not all of the meat grills are used when in use, but also prevents an overload on a motor provided in the exhaust duct when one of the multiple meat grills is used to grill meat and the other is used to cook soup, while allowing the temperature transmitted from the firepower of the meat grill used to cook soup to be transferred to the soup.

[0002] In general, considering that a lot of smoke is generated when grilling meat, which stings the eyes and makes breathing difficult, a smoke exhauster is installed to exhaust the smoke generated during the grilling process to the outside.

[0003] In particular, in the case of public restaurants, multiple grills are installed at designated intervals, and smoke exhausters are installed on top of each grill.

[0004] Figure 1 is a drawing showing a conventional smoke exhauster equipped with a meat grill.

[0005] As shown, a conventional smoke exhauster equipped with a meat grill is installed in an exhaust duct (11) installed in a public restaurant, and a plurality of smoke exhaust pipes (12) are installed downward at predetermined intervals.

[0006] And at the lower part of the smoke exhaust pipe (12), a heating device (17) such as a charcoal grill or gas stove is installed on the table, and a grill (16) is placed on the installed heating device (17), and when meat (18) is placed on the grill (16), the meat placed on the grill (16) is grilled by the heat emitted from the heating device (17).

[0007] In addition, a suction pipe (13) is installed at the bottom of the smoke exhaust pipe (12) to suck in the smoke generated during the process of grilling meat and discharge it to the outside through the smoke exhaust pipe (12) and exhaust duct (11).

[0008] At this time, the smoke exhaust pipe (12) is in the form of a corrugated pipe, and is lowered as much as possible on the grill (16), thereby preventing the smoke generated during the process of grilling meat from leaking out to the surroundings of the restaurant.

[0009] Despite these advantages, conventional smoke exhausters have a problem in that the smoke exhaust pipe (12) of a corrugated pipe type must be extended to suck up the smoke generated during the process of grilling meat, and the suction pipe (13) must be positioned as close to the grill (16) as possible, which not only limits the field of vision necessary for grilling meat, but also makes it difficult to pick up the meat when eating cooked meat due to the smoke exhaust pipe (12) and suction pipe (13) being positioned directly above the grill (16).

[0010] To solve this problem, other conventional smoke exhausters are provided by placing the smoke exhaust pipe (51) inside the meat grill.

[0011] Figure 2 is a drawing showing another conventional smoke exhauster equipped for grilling meat.

[0012] First, the meat grill is placed on the floor and is composed of an outer body (20) that is open at the top and bottom, a table (30) that is fixedly installed along the edge of the upper part of the outer body (20), and an inner body (40) that is fixed to the inner upper part of the outer body (20), is open at the top and bottom, and has a heating device (not shown) installed therein.

[0013] Another conventional smoke exhauster equipped with a meat grill, such as this, is composed of a smoke exhaust pipe (51) whose upper end is connected to the lower end of the inner body (40), a hinge shaft (52) rotatably connected to the smoke exhaust pipe (51), an opening / closing plate (53) connected to the hinge shaft (52) to open / close the inside of the smoke exhaust pipe (51), and a driving unit (54) connected to the hinge shaft (52) of the smoke exhaust pipe (51) to transmit driving force in a forward or reverse direction.

[0014] And, an exhaust duct (11) is embedded in the lower part of the outer body (20), and the lower part of the smoke exhaust pipe (51) is connected to the embedded exhaust duct (11). Here, the exhaust duct (11) is equipped with a motor connected to an exhaust fan to perform an exhaust function.

[0015] In this way, the number of smoke exhaust pipes (51) connected to the exhaust duct (11) is provided in multiple numbers to enable use by multiple customers due to the nature of public restaurants.

[0016] Through this, when grilling meat using multiple grills, for example, four grills connected to the exhaust duct (11), first, the driving unit provided in the grills for grilling meat is operated to rotate the opening / closing plate (53) connected to the smoke exhaust pipe (51) in a direction that opens the flow path of the smoke exhaust pipe (51), and then the exhaust duct (11) is driven.

[0017] Afterwards, when meat is placed on a grill plate with a burner, which is a heating device, installed in the inner body (40) of the meat grill, the smoke generated while the meat is grilled flows toward the inner body (40) located at the bottom and is exhausted to the outside through the exhaust duct (11).

[0018] Accordingly, users can comfortably grill and eat meat without any obstacles on top of the grill, without inhaling the smoke generated during the grilling process.

[0019] However, despite these advantages, other conventional smoke exhausters have the following problems.

[0020] Since several grills are placed in a public restaurant, for example, four grills are connected to one exhaust duct (11) to exhaust smoke.

[0021] For this reason, since the exhaust volume of the exhaust duct (11) is determined by considering the amount of smoke generated from about four grills, when only two grills are used, the flow path of the smoke exhaust pipe (51) provided for the two grills that are not used is closed, so there is a problem of overloading the motor provided in the exhaust duct (11).

[0022] To resolve this, the flow path of the smoke exhaust pipe (51) provided in all meat grills connected to the exhaust duct (11) can be opened and used, but this also has the following problems.

[0023] In the case of food cooked in a meat grill, soup dishes such as soybean paste stew are also prepared in addition to grilling meat. The soup dishes must be heated to a high temperature to heat room temperature water to a high temperature, but since the flow path of the smoke exhaust pipe (51) is open, the temperature is lower than the firepower provided by the intake through the exhaust duct (11), so not only does it take a relatively long time to prepare the soup dish, but there is also the problem that the taste is also reduced by half.

[0024] The present invention is to solve the problems of the above-mentioned prior art, and the purpose of the present invention is to provide a smoke exhaust device for a meat grill that not only does not overload the motor provided in the exhaust duct even when multiple meat grills are connected to one exhaust duct and not all of the meat grills are used when in use, but also does not overload the motor provided in the exhaust duct even when one of the multiple meat grills is grilling meat and the other is cooking soup, and the temperature transmitted from the firepower of the meat grill cooking soup is transferred to the soup as is.

[0025] In order to achieve the present invention, a smoke exhaust device for a meat roaster according to the present invention comprises: an exhaust duct having an exhaust fan connected to a duct-side motor installed therein to perform exhaust; at least two meat roasters; and a smoke exhauster positioned inside the meat roaster and communicating between the exhaust duct and the meat roaster; wherein the smoke exhauster comprises: a smoke exhaust body having an upper and lower opening, an upper end of which is connected to a lower end of an inner body disposed inside the meat roaster and a lower end of which is connected to the exhaust duct; a basic opening / closing plate rotatably installed inside the smoke exhaust body via a basic side hinge shaft for opening and closing a flow path of the smoke exhaust body; a driving unit connected to the basic side hinge shaft of the basic opening / closing plate and transmitting a driving force in a forward direction for closing the flow path of the basic opening / closing plate or in a reverse direction for opening the flow path of the basic opening / closing plate; A bypass body having left and right openings, one end of which is connected to the side of the basic opening plate; a bypass-side opening / closing plate that is rotatably installed in the bypass body via a bypass-side rotating member to open and close a flow path of the bypass body; and a plate adjustment unit having one end attached to one surface of the basic opening / closing plate, and for transmitting a driving force in a forward direction from the driving unit to close the flow path of the basic opening / closing plate, so that when the basic opening / closing plate rotates in the forward direction, the other end pressurizes and rotates one surface of the bypass-side opening / closing plate to open the flow path of the bypass body; wherein air flowing into the smoke exhaust body due to exhaust of the exhaust duct is introduced through the opened other end of the bypass-side opening / closing plate.

[0026] In the above driving unit, a driving force is transmitted in the reverse direction to open the flow path of the basic opening / closing plate, and when the basic opening / closing plate rotates in the reverse direction, the other end of the plate adjustment part that is in pressure contact with one surface of the bypass opening / closing plate is released from contact, and air flowing into the smoke exhaust body due to exhaust of the exhaust duct is introduced through the inner body of the meat grill.

[0027] The bypass side rotating member installed in the above bypass body is characterized by being a hinge.

[0028] The bypass-side rotating member installed in the above-mentioned bypass body is characterized by being a bypass-side hinge axis.

[0029] The installation direction of the bypass side hinge axis installed in the bypass body is installed in a direction parallel to the floor surface or a direction perpendicular to the floor surface.

[0030] The smoke exhaust device for a meat grill of the present invention further includes a rotation restriction line made of a bendable material, one end of which is connected to the bypass side opening / closing plate and the other end of which is connected to the plate adjustment part, thereby restricting rotation of the bypass side opening / closing plate in the direction of opening due to air flowing in through the inner body of the meat grill.

[0031] The above plate adjustment part comprises a connecting member attached to one side of the basic opening / closing plate;

[0032] It consists of a pressure member that is bent and extended from the other end of the above connecting member.

[0033] According to another embodiment, a smoke exhaust device for a meat roaster of the present invention comprises: an exhaust duct having an exhaust fan connected to a driving motor installed therein to perform exhaust; at least two meat roasters; and a smoke exhauster positioned inside the meat roaster and communicating between the exhaust duct and the meat roaster; wherein the smoke exhauster comprises: a smoke exhaust body having an upper and lower opening, an upper end communicating with a lower end of an inner body disposed inside the meat roaster, a lower end communicating with the exhaust duct, and a side opening to form an opening area through which the opening area passes; a basic opening / closing plate rotatably installed inside the smoke exhaust body via a basic side hinge axis for opening and closing a flow path of the smoke exhaust body; a driving unit connected to the basic side hinge axis of the basic opening / closing plate and transmitting a driving force in a forward direction for closing the flow path of the basic opening / closing plate or in a reverse direction for opening the flow path of the basic opening / closing plate; A method for closing an opening area formed through a side of the basic opening plate, the method comprising: a rotating body rotatably connected to the basic opening plate via a hinge; one end of which is attached to one side of the basic opening plate, and a driving force is transmitted in a forward direction from the driving unit to close a flow path of the basic opening plate, and when the basic opening plate rotates in the forward direction, the other end pressurizes and rotates one side of the rotating body to open the opening area of ​​the smoke exhausting body; and air flowing into the smoke exhausting body due to exhaust of the exhaust duct is introduced through the opening area.

[0047] The present invention relates to a smoke exhaust device for a meat grill, which not only prevents an overload on a motor provided in a corresponding exhaust duct when multiple meat grills are connected to a single exhaust duct and not all of the meat grills are used when not all of the meat grills are used, but also prevents an overload on a motor provided in a corresponding exhaust duct when one of the multiple meat grills is used to grill meat and the other is used to cook soup, while allowing the temperature transmitted from the firepower of the meat grill used to cook soup to be transferred to the soup as is, the smoke exhaust device comprising: an exhaust duct (11); at least two meat grills (A); and a smoke exhaust device (B); wherein the smoke exhaust device (B) comprises: a smoke exhaust body (100); a basic opening / closing plate (110); a driving unit (120); a bypass body (130); a bypass-side opening / closing plate (140); It includes a plate adjustment unit (150); and is characterized in that air flowing into the smoke exhaust body (100) due to exhaust of the exhaust duct (11) is introduced through the open other end of the bypass body (130).

[0048] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined by the description of the claims.

[0049] Meanwhile, the terminology used in this specification is for the purpose of describing embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. As used herein, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, operations, and / or elements to the mentioned components, steps, operations, and / or elements. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0050] As illustrated in FIGS. 3 to 9, when multiple meat roasters are connected to one exhaust duct and not all of the meat roasters are used, the motors provided in the exhaust ducts are not overloaded, and even when one of the multiple meat roasters is grilling meat and the other is cooking soup, the smoke exhaust device for meat roasters of the present invention is provided in the meat roasters so that the temperature transmitted from the firepower of the meat roaster cooking soup is transmitted to the soup as is, without overloading the motors provided in the exhaust ducts, and is composed of exhaust ducts (11) and smoke exhausters provided in the multiple meat roasters (A).

[0051] First, the exhaust duct (11) is a member that performs exhaust by having an exhaust fan (62) connected to a duct-side motor (61) installed inside.

[0052] The exhaust duct (11) performing this function may be installed buried in the floor of a public restaurant or may be installed on the floor of the public restaurant. Meanwhile, when installed on the floor of a public restaurant, a protective tube may be provided on the outside to protect it from dynamic shock transmitted from the outside.

[0053] The above meat grill (A) is placed on the floor of a public restaurant and is composed of an outer body (20) that is open at the top and bottom, a table (30) that is fixedly installed along the edge of the upper part of the outer body (20), and an inner body (40) that is fixed to the inner upper part of the outer body (20), is open at the top and bottom, and has a heating device installed therein.

[0054] In particular, a mounting cylinder (41) having a heating device inside is fixedly installed in the inner body (40). The outer diameter of the fixed mounting cylinder (41) is manufactured to be smaller than the inner diameter of the inner body (40) and is installed spaced apart from each other, thereby forming a flow path for air to flow between the mounting cylinder (41) and the inner body (40). Accordingly, it is preferable that the shapes of the mounting cylinder (41) and the inner body (40) are formed to be identical to each other. That is, as shown in the drawing, the mounting cylinder (41) and the inner body (40) can be formed into a cylinder.

[0055] And in the case of a heating device placed inside the casing (41), as shown in the drawing, a burner (42) that transmits a heat source through gas or a charcoal container in which charcoal is stored can be selected and used.

[0056] In addition, a cylindrical suction ring (43) having holes formed at predetermined intervals along the side to allow air to flow may be provided, which is optionally installed on the top of the holder (41). Through this, smoke generated when grilling meat flows through the holes of the suction ring (43) into the flow path between the holder (41) and the inner body (40).

[0057] And, a table (30) is connected and installed on the top of the outer body (20) so that food can be placed on it, and a hole is provided through the center of the table (30) so that a support member (31) such as a grill plate or a grill plate can be placed on it.

[0058] Here, the support member (31) may be provided mounted directly above the suction ring body (43), although not shown in the drawing.

[0059] At least two meat grills (A) having such a configuration are provided connected to the exhaust duct (11). In the embodiment of the present invention, four are described as being connected.

[0060] The above smoke exhauster (B) is located inside the meat grill (A) and is a member that connects the exhaust duct (11) and the meat grill (A).

[0061] The detailed configuration of the smoke exhauster (B) that performs this function is composed of a smoke exhaust body (100), a basic opening / closing plate (110), a driving unit (120), a bypass body (130), a bypass side opening / closing plate (140), and a plate adjustment unit (150).

[0062] First, the smoke exhaust pipe (100) is a tubular member that is open at the top and bottom, and the upper part is connected to the lower part of the inner body (40) placed inside the meat grill (A), and the lower part is connected to the exhaust duct (11).

[0063] The above basic opening / closing plate (110) opens and closes the flow path of the smoke exhausting body (100), and is a member that is rotatably installed through a basic side hinge axis (111) within the smoke exhausting body (100). That is, the basic side hinge axis (111) penetrates the smoke exhausting body (100) and is rotatably installed, and the basic opening / closing plate (110) is provided by being fixedly connected to the basic side hinge axis (111) located within the smoke exhausting body (100).

[0064] The basic opening / closing plate (110) performing such a function may be formed in a shape corresponding to the shape of the smoke exhaust body (100). In this embodiment, it is expressed in a cylindrical shape, but various shapes such as a polygonal shape including an oval shape or a square shape can be selected and used depending on the selection.

[0065] The above driving unit (120) is fixedly installed on the outer surface of the smoke exhaust body (100) and is provided in the form of a circuit board (PCB). Here, the driving unit (120), which is a circuit board (PCB), is provided with a plate-side motor (121) and is connected to the basic side hinge axis (111) of the basic opening / closing plate (110), thereby transmitting driving force in the forward direction for closing the flow path of the basic opening / closing plate (110) or in the reverse direction for opening the flow path of the basic opening / closing plate (110).

[0066] The above-mentioned plate motor (121) can use a motor capable of forward and reverse rotation, such as a stepping motor or a servo motor.

[0067] In addition, a power cord (102) is connected to the driving unit (120) so that power can be supplied through a commercial power source such as 110 V or 220 V, and a driving switch (103) is connected to request driving the plate motor (121) in forward or reverse rotation.

[0068] The above-mentioned bypass body (130) is a body member that is open on both sides and has one end connected to the side of the basic opening / closing plate (110). The shape of this bypass body (130) can be provided in the same shape as the bypass body (130).

[0069] The above-described bypass-side opening / closing plate (140) opens and closes the flow path of the bypass body (130), and is a member that is installed rotatably through a bypass-side rotating member within the bypass body (130), and may be formed in a shape corresponding to the shape of the bypass body (130). In the present embodiment, it is expressed in a cylindrical shape, but various shapes such as a polygonal shape including an oval shape or a square shape can be selected and used depending on the selection.

[0070] Here, the bypass-side rotating member installed in the bypass body (130) can be used by selecting either a hinge (141) or a bypass-side hinge axis (142).

[0071] Meanwhile, if a bypass hinge axis (142) is specified as a bypass rotation member installed in a bypass body (130), the installation direction of the bypass hinge axis (142) can be provided by being installed in a direction parallel to the floor surface or a direction perpendicular to the floor surface.

[0072] In addition, in the smoke exhaust device for a meat roaster of the present invention, a rotation limiting string (143) made of a bendable material, one side of which is connected to the bypass side opening plate (140) and the other side of which is connected to the plate adjustment part (150), is provided to limit rotation of the bypass side opening plate (140) in the direction of opening due to air flowing in through the inner body (40) of the meat roaster (A).

[0073]

[0074] *The material of the rotation limiting line (143) that performs this function can be made of cotton or synthetic fiber.

[0075] The above-mentioned plate adjustment part (150) is a member that is attached to one side of the basic opening / closing plate (110) at one end, and transmits driving force in the forward direction from the driving part (120) to close the flow path of the basic opening / closing plate (110), so that when the basic opening / closing plate (110) rotates in the forward direction, the other end pressurizes and rotates one side of the bypass-side opening / closing plate (140), thereby opening the flow path of the bypass body (130).

[0076] The detailed configuration of the plate adjustment unit (150) performing such a function may be composed of a connecting member (151) attached to one side of the basic opening / closing plate (110) and a pressure member (152) that is bent and extended from the other end of the connecting member (151).

[0077] Through this, in the smoke exhaust device for a meat roaster of the present invention, the air flowing into the smoke exhaust body (100) due to the exhaust of the exhaust duct (11) is controlled to flow in through the open other end of the bypass body (130), so that even when a soup dish is made in one of the four meat roasters connected to one exhaust duct (11), the duct-side motor (61) provided in the corresponding exhaust duct (11) is not overloaded, and the temperature transferred from the firepower of the meat roaster making the soup dish is transferred to the soup dish as is, thereby shortening the cooking time for the soup dish and providing the advantage of inducing a proper taste of the soup dish.

[0078] In addition, in the smoke exhaust device for a meat grill of the present invention, when the driving force is transmitted in the reverse direction from the driving unit (120) to open the flow path of the basic opening / closing plate (110), the basic side hinge shaft (111) connected to the plate side motor (121) of the driving unit (120) rotates in the reverse direction, and the plate adjustment part (150) connected to the basic opening / closing plate (110) also works in conjunction, so that the other end of the plate adjustment part (150) that is in pressure contact with one surface of the bypass side opening / closing plate (140) is released from contact, and the air flowing into the smoke exhausting body (100) due to the exhaust of the exhaust duct (11) is introduced through the inner body (40) of the meat grill (A), so that the smoke generated in the process of grilling meat flows toward the exhaust duct (11) via the smoke exhausting body (100) through the flow path between the holding body (41) and the inner body (40).

[0079] FIG. 11 is a drawing showing the operating state of a bypass-side rotating member among the components of a smoke exhaust device for a meat grill according to another embodiment of the present invention, and FIG. 12 is a drawing showing that a plurality of smoke exhaust devices for a meat grill according to another embodiment of the present invention are provided in a meat grill.

[0080] As shown in the drawing, in the smoke exhaust device for a meat grill according to another embodiment of the present invention, the installation structure of the smoke exhaust body (100) is changed to simplify and miniaturize the configuration.

[0081] That is, in the smoke exhaust device for a meat grill according to another embodiment of the present invention, an exhaust fan (62) connected to a duct-side motor (61) is installed inside, and the exhaust duct (11) that performs exhaust and the plurality of meat grills (A) are provided with the same configuration and operational combination, so detailed descriptions will be omitted.

[0082] In addition, the smoke exhauster (B) located inside the meat grill (A) and connecting the exhaust duct (11) and the meat grill (A) is also provided with the same operating combination except for some configurations, so the explanation will be focused on the changed parts.

[0083] That is, the changed parts of the smoke exhaust device (B) are the smoke exhaust body (100) and the rotating body (200).

[0084]

[0085] *First, the smoke exhausting body (100) is a cylindrical member that is open at the top and bottom, with the top connected to the bottom of the inner body (40) placed inside the meat grill (A), the bottom connected to the exhaust duct (11), and the side opened to form an opening area (101) therethrough. Here, the opening area (101) may be formed in various shapes such as a circle or a polygon, and in the embodiment of the present invention, a circle is specifically described.

[0086] The above-mentioned rotating body (200) is a tubular member that is rotatably connected to the basic opening / closing plate (110) via a hinge (210) to close the opening area (101) formed through the side of the basic opening / closing plate (110), and its shape may be formed in a shape corresponding to the opening area (101). In the embodiment of the present invention, it is specifically described as a cylindrical body. In addition, the thickness of the rotating body (200) is made 1.5 to 4 times larger than the thickness of the smoke exhausting cylinder (100), so as to open at a maximum right angle and to prevent opening due to the influence of air flowing due to its own weight in advance.

[0087] Through this, in the smoke exhaust device for a meat roaster of the present invention according to another embodiment, the air flowing into the smoke exhaust body (100) due to the exhaust of the exhaust duct (11) is controlled to flow in through the opening area (101), so that even when a soup dish is made in one of the four meat roasters connected to one exhaust duct (11), the duct-side motor (61) provided in the exhaust duct (11) is not overloaded, and the temperature transferred from the firepower of the meat roaster making the soup dish is transferred to the soup dish as is, thereby shortening the cooking time for the soup dish and providing the advantage of inducing a proper taste of the soup dish.

[0088] In addition, in the smoke exhaust device for a meat grill according to another embodiment of the present invention, when the driving force is transmitted in the reverse direction from the driving unit (120) to open the flow path of the basic opening / closing plate (110), the basic side hinge shaft (111) connected to the plate side motor (121) of the driving unit (120) rotates in the reverse direction, and the plate adjustment part (150) connected to the basic opening / closing plate (110) also works in conjunction, so that the other end of the plate adjustment part (150) that is in pressurized contact with one surface of the rotating body (200) is released from contact, and the rotating body (200) closes the opening area (101) of the smoke exhaust tube (100) due to its own weight.

[0089] Through this, the air flowing into the smoke exhaust body (100) due to the exhaust of the exhaust duct (11) is introduced through the inner body (40) of the meat grill (A), so that the smoke generated during the process of grilling meat flows toward the exhaust duct (11) via the smoke exhaust body (100) through the flow path between the grilling body (41) and the inner body (40).

[0090] The smoke exhaust device for a meat roaster of the present invention is characterized in that, when multiple meat roasters are connected to a single exhaust duct and not all of the meat roasters are used, the motor provided in the corresponding exhaust duct is not overloaded, and even when one of the multiple meat roasters is grilling meat and the other is cooking soup, the motor provided in the corresponding exhaust duct is not overloaded, and the temperature transmitted from the firepower of the meat roaster cooking soup is transmitted to the soup as is.
