Description

Versatile food heating device

The present invention relates to a multipurpose food heating device, and more specifically, to a multipurpose food heating device that enables uniform cooking by far-infrared rays and can be used for various purposes by changing its shape.

Charcoal grilling is a popular method for cooking food, especially meat. Charcoal grilling is a method of lighting charcoal or fire on the bottom of a grill, placing a grill plate or cooking grate on top, and grilling the ingredients on top. This is called direct grilling.

Direct grilling is a method that mainly uses radiant heat directly emitted from a heat source, but it requires high temperature heat, and since the temperature of the cooking surface is high, approximately 250℃, there is a problem that it is difficult to cook thick or large ingredients thoroughly.

In addition, there is a problem that because the material and the heat source are close, the exhaust such as oil dripping from the material falls directly on the heat source and burns, generating acrid smoke and harmful gases.

Accordingly, the need for and public interest in indirect grilling are gradually increasing. In Korea, cooking methods based on traditional materials that emit far-infrared rays, such as yellow clay, jars, and slate, have been developed, and there have been many attempts to develop advanced cooking utensils based on these. Korean Patent No. 10-0936422 (2010.01.05) discloses a barbecue grill. This performs barbecue by utilizing far-infrared rays emitted from an inner wall formed of yellow clay due to the heat provided by charcoal, but there are problems in that the temperature and humidity of the yellow clay applied to the inner wall change, or it absorbs oil and cracks, generating sand dust, and the charcoal in the heating chamber is biased to the side, causing an uneven temperature distribution inside the cooking chamber.

Republic of Korea Patent No. 10-0936422

FIG. 1 is a perspective view showing a combined state of a multipurpose food heating device according to one embodiment of the present invention, FIG. 2 is an exploded perspective view showing detailed components of a multipurpose food heating device according to one embodiment of the present invention, and FIG. 3 is a perspective view showing a cover according to one embodiment of the present invention.

As illustrated in FIGS. 1 to 3, a multipurpose food heating device according to one embodiment of the present invention includes a cover (100), an upper body (200), a receiving member (300), a lower body (400), and a furnace (500). The multipurpose food heating device of the present invention may not include at least one of the cover (100), the upper body (200), and the receiving member (300) according to various application examples described below.

The cover (100) can be mounted on the upper part of the upper body (200) and can serve to prevent heat from escaping through the open upper part of the upper body (200) when heat is supplied to the multipurpose food heating device. The cover (100) can have a shape that is hollow inside, has one side open, and the other side closed. The shape of the cover (100) can be applied without limitation as long as it can cover the open upper part of the upper body (200) and block heat energy from escaping through the open upper part. As shown in FIGS. 1 to 3, the cover (100) can have a shape of a jar lid that is large enough to sufficiently cover the open upper part of the upper body (200). Hereinafter, for the sake of clear understanding and convenience of explanation of the present invention, the cover (100) will be described as an example in the form of a jar lid.

At least one cover handle (102) may be formed on the outer surface of the cover (100), and a cover hole may be formed on the other surface of the cover (100). The cover hole (101) may be used to measure the internal temperature by inserting a thermometer into the cover hole (101) when the multipurpose food heating device according to the present invention is used for smoking purposes. According to another embodiment of the present invention, the cover (100) may be turned over and used as a cooking pan, and at this time, the cover hole (101) may be used as a hole through which the discharge of food cooked on the bottom surface of the cover (100) (i.e., the other surface of the cover (100)) (for example, oil discharged from pork belly when grilling pork belly) is discharged. If the cover hole (101) is used as a discharge port, the cover hole (101) may be formed to be slightly inclined downward so that the discharge of food cooked can be discharged smoothly. The location of the cover hole (101) can be selected so that when the centers of the bottom surfaces of the receiving member (300) and the cover (100) are aligned, the discharged matter falling from the cover hole (101) does not fall into the empty center of the receiving member (300) or flow to the outside of the receiving member (300).

The cover handle (102) is formed on the outer surface of the cover (100) and can be used when the cover is removed. There is no limitation on the material of the cover handle (102), but it is preferably the same as the cover (100). There is also no particular limitation on the method by which the cover handle (101) is fixed to the cover (100), such as welding or bonding, but it is preferable that the cover handle (101) is manufactured as an integral part with the cover (100) so that it is firmly fixed to the cover and can withstand high temperatures.

A pattern (wrinkle) for use as a steak grill can be formed on the inner surface (i.e., the inner bottom surface) of the cover (101).

The receiving member (300) is a component that can receive and collect the discharge falling from the food. While the food is being cooked, various discharges such as oil, blood, and body fluids fall. The receiving member (300) can allow the food discharges to be discharged to the outside instead of falling directly into the furnace (500). The receiving member (300) can have a closed belt shape with a U-shaped vertical cross-section and an empty center. The transverse cross-section of the receiving member (300) can be square or circular. When the transverse cross-section of the receiving member (300) is circular, the receiving member (300) can have an annular shape as illustrated in FIG. 2.

The width of the receiving member (300) may be configured to be wide enough so that the discharge falling from the food fixed to the hook can be collected in the receiving member (300) without falling into the furnace. The area of the empty center of the receiving member (300) is smaller than the area of the open top of the upper body (200). In other words, the receiving member (300) may be formed so that the opening formed in the center of the receiving member (300) is smaller than the diameter of the upper opening of the upper body (200).

A discharge spout (301) may be formed on the outer surface of the receiving member (300) to discharge food waste collected in the receiving member (300) to the outside of the multipurpose food heating device. The bottom surface of the receiving member (300) may be formed to have a slight slope so that food waste can be collected by the discharge spout (301).

At least one mounting member (302) protruding away from the center may be formed on the outer surface of the receiving member (300). For example, if the shape of the receiving member (300) is annular, at least one mounting member (302) may be formed radially along the outer surface of the receiving member (300). The mounting member (302) may be in the shape of a pin, a rod, or a plate with one end being longer, and the end portions of the pin, rod, and plate may be in a folded shape. However, any shape that can perform the function of the mounting member (302) may be applied without limitation. The receiving member (300) is mounted on the upper portion of the lower body (400) through the mounting member (302). A lower receiving groove (401) may be formed at the upper end of the lower body (400) to receive at least a portion of the mounting member (302), and as the mounting member (302) is received in the lower receiving groove (401), movement (e.g., rotational movement, horizontal movement, etc.) of the receiving member (300) received at the upper end of the lower body (400) may be restricted. An upper receiving groove (201) may be formed at the lower end of the upper body (200) to receive at least a portion of the mounting member (302). As the mounting member (302) is received in the upper receiving groove (201), movement of the upper body (200) may be restricted. The upper body (200) and the lower body (400) may have a shape in which the interior is hollow and the upper and lower ends are open. For example, the upper body (200) and the lower body (400) may have a columnar shape in which the interior is hollow and the upper and lower ends are open. The shape of the upper and lower cross sections of the upper body (200) and the lower body (400) may be circular, and the diameters of the upper and lower cross sections (i.e., circular) of each of the upper body (200) and the lower body (400) may be the same or different. In one embodiment of the present invention, the shape of the upper body (200) and the lower body (400) combined may be in the shape of a jar.

At least one hook groove (203) may be formed on the upper surface of the upper body (200). The hook groove (203) may be a small semicircular or U-shaped hole. The hook (204) may be caught in the hook groove (203) with food threaded thereon. When the hook with food threaded thereon is caught in the hook groove (203) and the cover (100) is placed on the top of the upper body (200), the hook (204) is pressed by the cover (100) and does not come off from the hook groove (203).

A discharge spout (301) may be formed on the outer surface of the receiving member (300) to discharge food waste accumulated in the receiving member (300) to the outside of the multipurpose food heating device, and a discharge spout receiving groove (403) may be formed on the upper end of the lower body (400) to receive at least a portion of the discharge spout (301). The discharge spout (301) is an opening formed in the lower body (400), and is preferably formed in a shape and size that does not interfere with the lower body (400) when the receiving member (300) is placed on the lower body (400), while being formed in a minimum size to prevent heat loss.

At least one upper body handle (202) may be formed on the outer surface of the upper body (200), and at least one lower body handle (402) may be formed on the outer surface of the lower body (400). The upper body handle (202) and the lower body handle (402) may be used when the upper body (200) and the lower body (400) are to be separated from each other or moved.

The furnace (500) is a component for supplying heat to the inside of the multipurpose food heating device according to the present invention. In addition, the furnace (500) can be fixed so that the entire multipurpose food heating device does not fall over. Since the lower body (400) is secured to the upper part of the furnace (500), it is preferable that the shape of the furnace has a cross-sectional shape (i.e., circular) whose diameter becomes narrower as it goes down, so that the lower body (400) does not fall over and is held together by its own weight.

A heating means may be placed inside the furnace (500). The heating means may include, but is not limited to, charcoal and gas commonly used for grilling, as well as briquettes, briquettes, electric heating wires, halogen lamps, and microwave emitters.

The multipurpose food heating device may further include a brazier bottom plate (501) having a plurality of perforations formed therein, and the brazier bottom plate (501) may be installed inside the brazier (500). A heat source such as charcoal or briquette may be placed on top of the brazier bottom plate (501). The brazier bottom plate (501) may adjust the height of the heat source applied to the brazier (500) while allowing by-products generated from the heat source to be discharged downward. For example, when charcoal is applied as a heat source, ash, which is a combustion by-product of the charcoal, gradually accumulates. The main component of the ash is potassium carbonate, which mainly has a bitter taste. When a small amount of ash is combined with meat, the potassium component contained in the ash neutralizes fatty acids contained in the meat, thereby having the effect of removing the gamey taste of the meat. However, due to the characteristics of smoked cooking with a long cooking time, ash continues to fly due to continuous convection inside, and may be attached to the food being cooked in large quantities. Because of this, there is a concern that ash may spoil the appearance of food and make it taste bitter, so it is necessary to appropriately control the amount of ash remaining. Accordingly, a brazier bottom plate (501) having multiple perforations formed therein is provided, and burning charcoal is placed on the top of the brazier bottom plate (501), so that most of the burned ash falls through the perforations to the bottom of the brazier bottom plate (501), and only unburned charcoal and a small amount of ash remain on the brazier bottom plate (501), so that effective cooking can be performed.

Hereinafter, the materials of the components will be described. The cover (100), the upper body (200), and the lower body (400) may be used without any particular restrictions as long as they are heat-resistant enough to withstand the heat used to grill meat and do not emit harmful substances at high temperatures. For example, the material of the cover (100), the upper body (200), and the lower body (400) may be earthenware made of sphagnum moss and yellow clay, which have been used in conventional jars. Alternatively, the material of the cover (100), the upper body (200), and the lower body (400) may be cast iron (pig iron). Cast iron enables even heating by wrapping heat around the entire surface, and therefore is suitable for dishes such as stir-frying and grilling that require high-temperature cooking in a short period of time. Additionally, unlike other cookware that has a high risk of peeling off the coating formed by chemicals or foreign materials, cookware made of cast iron can be used almost permanently through 'seasoning', which is a process of treating the surface with oil.

The inner surfaces of the cover (100), the upper body (200), and the lower body (400) may be surface-treated. For example, when earthenware composed of quartz and yellow clay is selected as the material constituting the cover (100), the upper body (200), and the lower body (400), a heat-resistant glaze may be required for the inner surface treatment. Alternatively, when cast iron is selected as the material constituting the cover (100), the upper body (200), and the lower body (400), Hexcel fusing may be applied to the surfaces. Hexcel fusing is a method of surface-treating through ceramic fusing at a high temperature of about 850°C, and compared to conventional general ceramic surface coatings that treat the surface through firing at 200 to 300°C, it has effects such as decomposition of organic matter, removal of odor, and improvement of far-infrared ray emissivity, and thus a synergistic effect may be generated when applied to a device that cooks food at a high temperature . Additionally, the microscopic pores on the surface are blocked by the Hexcel fusing coating, making dishwashing easier.

The receiving member (300), the furnace (500) and the hook (204) are preferably made of a material that does not combust under high temperature conditions and does not react with food. Preferably, the receiving member (300), the furnace (500) and the hook (204) can be made of stainless steel, but are not limited thereto.

The following describes examples of using the multipurpose food heating device according to the present invention for various purposes.

FIG. 4 is a cross-sectional perspective view showing an example of using a hook in a multipurpose food heating device according to the present invention for smoking purposes. Referring to FIG. 4, the multipurpose food heating device according to the present invention can be assembled in the following order from bottom to top: a furnace (500), a lower body (400), a receiving member (300), an upper body (200), and a cover (100). Food ingredients (e.g., grilled pork belly, beef ribs, etc.) can be threaded onto the hook (204), and the hook (204) with the food ingredients threaded onto it can be caught on the hook groove (203). A user can place the cover (100) on the upper part of the upper body (200) and insert a thermometer into the cover hole (101) to measure the internal temperature of the multipurpose food heating device for smoking. Thereafter, the user can operate the heating means of the furnace (500) and adjust the heat power appropriately so that the temperature inside the multipurpose food heating device becomes an appropriate level. The multipurpose food heating device for smoking according to the present invention may have a shape similar to a jar. Inside the multipurpose food heating device for smoking, heat can be continuously convectively circulated. In addition, the cooking temperature of the food material can be maintained constant by far-infrared rays emitted from the inner wall of the multipurpose food heating device for smoking. The discharge (for example, oil that comes out of the pork belly when grilling the pork belly) generated from the food material (for example, pork belly for grilling) hung on the hook (204) and falling can be collected in the receiving member (300) without falling into the furnace (500). This is because the diameter of the opening formed in the center of the receiving member (300) is formed smaller than the diameter of the upper opening of the upper body (200), so that the width of the receiving member (300) is sufficient to receive and collect the output. Most of the oil and other discharges that fall from the food being cooked are collected in the receiving member (300), so that they do not fall into the furnace through the empty space in the center of the receiving member (300). The discharge collected in the receiving member (300) is discharged to the outside of the multipurpose food heating device through the discharge spout (301), so that even when cooking for a long time, the discharge does not overflow from the receiving member (300) or burn due to high temperature, but continues to be discharged to the outside, so that a pleasant cooking environment can be maintained. And, since the cover (100) is covered, heat is not released to the outside, and the cover (100) presses the hook groove (203) where the hook (204) is caught, so that the hook (204) does not come off the hook groove (203), so that smoking cooking can be performed for a long time without worrying about the food falling.

In the smoked cooking method, the heating temperature of the meat is preferably 140℃~180℃. The cooking time varies depending on various conditions such as the type of meat, thickness, and desired cooking degree, but it is recommended to approximately 12 hours at 140℃, 4 hours at 160℃, and 1 hour to 30 minutes at 180℃.

According to another application example of the present invention, the multipurpose food heating device may include only the lower body (400) excluding the upper body (200). Various application examples of the present invention are illustrated in FIGS. 5 to 7, but such applications do not limit or restrict the scope of the present invention. FIG. 5 is a drawing showing an application example of using the cover (100) of the multipurpose food heating device according to the present invention as a steak grill. As illustrated in FIG. 5, the flipped cover (100) may be placed on the upper portion of the receiving member (300). Here, the diameter of the bottom surface of the cover (100) is formed larger than the diameter of the central opening of the receiving member (300) so that the cover (100) does not fall into the receiving member (300). At this time, the furnace (500) may be used in the same manner as the examples described above through FIGS. 1 to 4. In order for the cover (100) to be used as a steak grill, grill wrinkles may be formed on the inner side of the bottom surface of the cover (100). The cover (100) may have a cover hole (101) formed therein so that food waste can be discharged. At this time, since the location of the cover hole (101) is selected so that food waste falling through the cover hole (101) does not go out through the opening of the receiving member (300) or the outside of the lower body (400), the food waste can be collected in the receiving member (300). FIG. 6 is a drawing showing an example of using a ceramic ball grill in a multipurpose food heating device according to the present invention. The ceramic ball grill is configured by inserting a plurality of ceramic balls between two pieces of wire mesh facing each other, and since the specific heat of the ceramic balls is high and the thermal conductivity is low, the ingredients do not burn during the cooking process and are easy to keep warm, so it is suitable for thick meat or grilled fish.

Figure 7 is a drawing showing an example of using a stir-fry plate in a multipurpose food heating device according to the present invention. When using a stir-fry plate, it can be used by removing the receiving member (300) or can be used without removing the receiving member (300). The stir-fry plate can easily perform various stir-fry dishes over a large area.

Figure 8 is a drawing showing an example of using a pot in a multipurpose food heating device according to the present invention. A user can cook soup by placing a pot larger than the opening in the center of the receiving member (300) or a pot of an appropriate size that can be hung on the opening in the center of the receiving member (300).
