Description

[Technical Field]

[0001] The present invention relates to a household cooking appliance, and more particularly to an indirect heat type cooking appliance that can be used at home and can cook food using indirect heat containing far infrared rays. [Background technology]

[0002] In general, cooking utensils are tools used for cooking, as defined in the dictionary, and include large appliances, cooking tools, and kitchen equipment. The material, structure, and performance of the utensils affect the efficiency of cooking, the appearance of the food, the economy of ingredients and heat sources, and hygiene. They can be classified in various ways, such as for home use or large-scale cooking, by type of cuisine (Korean, Japanese, Western, or home-cooked), and by type of cooking operation. There are multi-purpose appliances and appliances with a narrower range of uses, and some appliances can be used for multiple purposes by replacing parts, and they can be divided into kettles, steamers, grills, various pots, etc.

[0003] Korean Patent Registration No. 10-2142110 discloses a conventional cookware using a far-infrared radiating material (hereinafter referred to as the conventional cookware). The conventional cookware includes a tray body that is directly heated by a heater, a cooking table that is high in the center and low in the periphery and is configured to be placed on the table portion of the tray body and has a number of heating holes formed throughout to allow hot air to pass from top to bottom, an oil-collecting ring-shaped groove that is formed in a ring shape around the periphery of the tray body and is configured to collect oil discharged from the food to be cooked through the cooking table during cooking, and a far-infrared radiator in liquid or powder form that is housed inside the heating portion of the tray body and emits far-infrared rays to the cooking table above when heated by the heater, thereby indirectly heating the food to be cooked and allowing the far-infrared rays to penetrate the food to be cooked.

[0004] However, when used at home, conventional cookware has problems such as the oil from the food being cooked dripping onto the tray body or heating element due to the numerous heating holes that allow far infrared rays to pass directly through the food being cooked, resulting in smoke. Also, because the heat from the heating element, along with far infrared rays, passes directly through the numerous heating holes to the food being cooked, the bottom of the food being cooked earlier than the top, forcing the user to periodically turn the food being cooked over.

[0005] Furthermore, conventional cookware has a drawback in that the oil-collecting groove is formed in a circular shape around the basin body, making it difficult to separate from the basin body and difficult to clean. Most of the oil from the food being cooked collects in the oil-collecting groove, making it necessary to clean the oil-collecting groove after use. However, to clean the oil-collecting groove, the user must inconveniently remove each of the far-infrared radiators inside the basin body that are physically connected to the oil-collecting groove.

[0011] According to an embodiment, the cover may include a circular plate having a second through hole formed in the center through which the fastener passes, and legs extending downward from the edge of the circular plate and surrounding the first bent portion.

[0012] According to an embodiment, the legs may include alternating protrusions and recesses.

[0013] According to an embodiment, the discharge path can be formed via a gap between the recess and the exhaust port.

[0014] According to an embodiment, the discharge groove may be formed with a discharge hole through which materials discharged from the food to be cooked are discharged to the outside of the upper container.

[0015] According to an embodiment, the lower container may include a heating section that protrudes downward to abut against the heating body and is configured to accommodate a far-infrared radiator that emits far-infrared rays when heated, a smoking section that extends outward from the upper end of the heating section and is configured to accommodate a fumigant at its upper portion, and a placing section that extends further outward from the edge of the smoking section and is configured to contact a lower portion of the upper container to place the upper container on.

[0016] According to an embodiment, the lower container may further include a sloped portion configured to form a step between the smoking section and the placing section. [Effects of the Invention]

[0017] The home cooking appliance according to one embodiment of the present invention includes a cooking table with a hot air inlet, which prevents oil from dripping from the food being cooked into the lower container and effectively diffuses hot air from the heater into the upper container. This allows for indirect heat cooking at home and allows food to be cooked evenly and thoroughly in a short amount of time without having to be turned over in the upper container. Furthermore, the lower container includes a smoking section, allowing for effective smoked cooking with minimal use of smoking agent.

[0018] In addition, the household cooking utensil according to one embodiment of the present invention is easily cleaned by physically separating the upper container, which comes into contact with oil, from the lower container, which does not come into contact with oil, so that substances (e.g., oil) discharged from the food being cooked do not flow into the lower container but are discharged outside from the upper container. Furthermore, the far-infrared radiator in the lower container can be reused semi-permanently without a separate cleaning process. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, the embodiments of the present invention will be described clearly and in detail to the extent that a person skilled in the art can easily practice the present invention. However, since the present invention can be embodied in various different forms within the scope of the claims, the embodiments described below are merely examples, regardless of expression. In other words, the present invention is not limited to the embodiments disclosed below, but can be embodied in various different forms.

[0021] The terms used in this application are used only to describe specific embodiments and are not intended to limit the present invention. The singular expressions include the plural expressions unless the context clearly dictates otherwise. In this application, the terms "comprise" or "have" are intended to specify the presence of features, numbers, steps, operations, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the presence or additional possibility of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0022] Terms such as "first" and "second" may be used to describe various components, but the components should not be limited by these terms. These terms are used only to distinguish one component from another.

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0024] 1 to 3 show a household cooking appliance according to one embodiment of the present invention, in which FIG. 1 is a perspective view of the household cooking appliance 100, FIG. 2 is a front or side view of the household cooking appliance 100, and FIG. 3 is a bottom view of the household cooking appliance.

[0025] The domestic cooking appliance 100 may include a lower container 110, an upper container 120, and a lid 130. The domestic cooking appliance 100 may be an indirect heat cooking appliance that can be used at home. Indirect heat cooking refers to a cooking method in which an object to be cooked is cooked by indirect heat using a medium such as air or water without the object being in direct physical contact with a heating element.

[0026] In the household cooking appliance 100, the lower container 110 receives heat directly from the heater and transfers the heat to the upper container 120 through a medium accommodated inside the lower container 110, thereby cooking the food inside the upper container 120. In addition, the lid 130 minimizes the outflow of the heat transferred to the upper container 120, thereby maintaining the temperature inside the upper container 120 at a certain temperature or higher.

[0027] According to an embodiment, the lower container 110 may accommodate a far-infrared radiator. The far-infrared radiator may be a material that emits far-infrared rays, such as a mixture of one or more of loess, charcoal, tourmaline, germanium, maifan stone, and ceramics, or a composition obtained by mixing the mixture with powdered herbal medicine or boiled herbal medicine.

[0028] As a result, the household cooking appliance 100 can emit a large amount of far infrared rays during heating, which allows the far infrared rays to penetrate deep into the food to heat it quickly and evenly, while also removing the odor of the food and expelling high-fat oil from the food to further improve the taste and aroma without burning it.

[0029] Next, for convenience of explanation, the household cooking appliance 100 will be described using grilling as an example. However, the household cooking appliance 100 should not be understood as a cooking appliance limited to grilling, and a person skilled in the art of the present invention will understand that the technical concept of the present invention can be easily applied not only to grilling but also to steaming, rice cooking, etc.

[0030] Fig. 4 is an exploded view of a household cooking utensil according to an embodiment of the present invention, Fig. 5 is a cross-sectional view of the lower container of Fig. 4, and Figs. 6 and 7 are views of the upper container of Fig. 4. Referring to Figs. 4 to 7, the household cooking utensil 100 may be stacked in the order of the lower container 110, the upper container 120, and the lid 130 from the bottom up.

[0031] The lower container 110 can be directly heated by a heating element below it. Although not shown, the heating element can include a household heating appliance. For example, the heating element can include a gas range, a highlighter, an induction heater, etc. The lower container 110 can include a heating section 111, a smoking section 112, an inclined section 113, and a placing section 114.

[0032] The heating unit 111 may be formed to protrude downward to contact the heating element, and may house a far-infrared radiator 115 that emits far-infrared rays when heated. The lower protrusion of the heating unit 111 is circular, and its diameter L may correspond to the diameter of the heating element. For example, if the heating element includes a burner with a diameter of 18 cm, the diameter L of the lower protrusion of the heating unit 111 may be 18 cm. That is, the size of the heating unit 111 may vary depending on the size of the burner.

[0033] The smoking section 112 may extend outward from the upper end of the heating section 111. A fumigant may be placed on the top of the smoking section 112. The fumigant is not directly heated by the heating element, but can generate smoke by heat conducted from the heating section 111. For this purpose, the lower container 110 may be made of a material with high thermal conductivity, such as stainless steel, aluminum, copper, cast iron, or enamel.

[0034] The inclined portion 113 may be configured to form a step between the smoking portion 112 and the placing portion 114. That is, the smoking portion 112 and the placing portion 114 may be separated by the inclined portion 113, and the step may provide a space in which the fumigant is placed on the smoking portion 112. Depending on the embodiment, the inclined portion 113 may be omitted, in which case the placing portion 114 may be configured to slope upward outward.

[0035] The mounting portion 114 may further extend outward from the edge of the smoking portion 112. The upper container 120 may be placed on the mounting portion 114. Depending on the embodiment, the cooking surface 121 of the upper container 120 may be configured with a downward slope outward. A lower portion of the cooking surface 121 may abut against the mounting portion 114, thereby allowing the upper container 120 to be placed on the mounting portion 114. Depending on the embodiment, the edge of the mounting portion 114 may contact the inner circumferential surface of the discharge groove 126.

[0036] The upper container 120 may be configured to accommodate food items therein and provide a cooking space so that the air heated in the lower container 110 can raise the internal temperature of the food items. The upper container 120 may include a cooking surface 121, an exhaust port 122, a cover 123, a fastener 124, a blade portion 125, and a discharge groove 126.

[0037] Food items can be placed on the cooking table 121. The cooking table 121 may have a disk shape and may be configured with a downward slope on the outside. This is to collect substances such as oil drained from the food items into drain grooves 126 located on the edge of the cooking table 121. Depending on the embodiment, the cooking table 121 may be made of a material with high thermal conductivity such as stainless steel, aluminum, copper, cast iron, or enamel.

[0038] The exhaust port 122, the cover 123, and the fasteners 124 may constitute a hot air inlet 1000. The hot air inlet 1000 is located at the center of the cooking table 121 and may be configured to discharge heated air flowing in from the lower container 110 along the surface of the cooking table 121. For example, air heated in the lower container 110 may enter the upper container 120 through an exhaust path formed by the exhaust port 122 and the cover 123, and the heated air may generate convection in the upper container 120 to cook food. The fasteners 124 may connect and fix the exhaust port 122 and the cover 123. This will be described in detail later with reference to FIGS. 9 to 11.

[0039] The wings 125 are located at the outermost side of the upper container 120, and the periphery of the lid 130 can be placed on the wings 125. The wings 125 extend outward from the top end of the upper container 120 by a certain distance, and a user can use the wings 125 as a handle to lift the upper container 120 and separate it from the lower container 110. According to an embodiment, a handle made of a material with low thermal conductivity, such as silicone, can be attached to the wings 125.

[0040] The blade portion 125 may be connected to a discharge groove 126. The discharge groove 126 is located at the edge of the cooking table 121, and materials discharged from the food to be cooked may be collected in the discharge groove 126 along the downward slope of the cooking table 121. The discharge groove 126 may be formed with a discharge hole H through which the materials discharged from the food to be cooked are discharged to the outside of the upper container 120. There may be one or more discharge holes H.

[0041] The lid 130 may cover the upper container 120 so that the food to be cooked is not exposed to the outside. A handle 135 may be formed at the center of the lid 130. The lid 130 may be made of tempered glass. According to an embodiment, the lid 130, the upper container 120, and the lower container 110 may all have the same central axis.

[0042] Fig. 8 is a cross-sectional view of the household cooking appliance of Fig. 2, Fig. 9 is an exploded view of the hot air inlet of Fig. 8, and Fig. 10 is a view showing the lower part of the cover of Fig. 9. Referring to Figs. 8 to 10, the upper container 120 may include a hot air inlet 1000.

[0043] The hot air inlet 1000 may include an exhaust port 122, a cover 123, and a fastener 124. The exhaust port 122 may include a plurality of inlet holes h1 through which air heated in the lower container 110 flows in. The air heated in the lower container 110 may enter the upper container 120 through the plurality of inlet holes h1.

[0044] According to an embodiment, the exhaust port 122 may have a circular shape and may have an upwardly convex shape as a whole. The exhaust port 122 may include a first bent portion 1221, a second bent portion 1222, a first connecting portion 1223, and a second connecting portion 1224.

[0045] The first bent portion 1221 may be annular and surround the outer periphery of the exhaust port 122. The first bent portion 1221 may be bent in a direction in which the absolute value of the surface gradient increases as it goes outward. The first bent portion 1221 may form a first step by bending. The first step may form a passage through which air flowing in from the lower container 110 can be discharged in relation to the cover 123, and may prevent oil and the like from flowing into the lower container 110 in relation to the cooking surface 121.

[0046] The second bent portion 1222 may be annular with a smaller diameter than the first bent portion 1221. The second bent portion 1222 may be bent in a direction in which the absolute value of the surface gradient increases toward the outside. The second bent portion 1222 may form a second step by bending to form a storage space for air introduced through the plurality of inlet holes h1. That is, the first bent portion 1221 and the second bent portion 1222 may form a two-step step.

[0047] The first connecting portion 1223 may be configured to connect the first bent portion 1221 and the second bent portion 1222. A plurality of inlet holes h1 may be formed in the first connecting portion 1223. The plurality of inlet holes h1 may be arranged at regular intervals along the circumferential direction of the first connecting portion 1223. Depending on the embodiment, the surface of the first connecting portion 1223 may have a regular inclination or may have an upwardly convex shape.

[0048] The second connecting portion 1224 may be configured to connect the interior of the second bent portion 1222. A first through hole h2 through which the fastener 124 passes may be formed in the second connecting portion 1224. The first through hole h2 may be located at the center of the second connecting portion 1224. Depending on the embodiment, the surface of the second connecting portion 1224 may have a constant slope or an upward convex shape.

[0049] The cover 123 may be configured to form an exhaust path for heated air while covering the exhaust port 122. The cover 123 may include a disk 1231 and legs 1232. A second through-hole h3 through which the fastener 124 passes may be formed in the center of the disk 1231. The legs 1232 may be positioned to extend downward from the edge of the disk 1231 and surround the first bent portion 1221.

[0050] The legs 1232 include convex portions (conv) and concave portions (conc), and the convex portions (conv) and concave portions (conc) may each be composed of a plurality of pieces and arranged alternately. According to an embodiment, the lower ends of the legs 1232 may be configured in a wavy shape. When the legs 1232 are positioned to surround the first bent portion 1221, a gap (G in FIG. 11) may be formed between the concave portion (conc) and the exhaust port 122. Heated air is discharged into the gap, forming an exhaust path.

[0051] The fastener 124 may be configured to connect the exhaust port 122 and the center of the cover 123. The fastener 124 may be fastened through the first through-hole h2 of the exhaust port 122 and the second through-hole h3 of the cover 123 to fix the exhaust port 122 and the cover 123. For example, the fastener 124 may fix the exhaust port 122 and the cover 123 by a bolt-nut connection. For example, the fastener 124 may fix the exhaust port 122 and the cover 123 by a rivet connection (rivet nail).

[0052] According to the embodiment, when the exhaust port 122 and the cover 123 are coupled, the second bent portion 1222 can create a gap between the exhaust port 122 and the cover 123. The disc 1231 may be flat or may have the same inclination as the first connecting portion 1223, and the upwardly convex second bent portion 1222 can fasten the disc 1231 to the first connecting portion 1223 at a distance. The heated air that has passed through the plurality of inlet holes h1 is stored in the gap between the exhaust port 122 and the cover 123, and can escape through the exhaust path when the pressure exceeds a certain level.

[0053] Figure 11 is a diagram showing the flow of air through the hot air inlet of Figure 8. Referring to Figure 11, the air heated in the lower container 110 rises and enters the upper container 120 through the hot air inlet 1000.

[0054] According to the embodiment, heated air can be stored in the gap between the exhaust port 122 and the cover 123 through the plurality of inlet holes h1. The exhaust port 122 can form a gap when coupled with the cover 123 by the second bent portion 1222. Heated air can be stored in the gap by passing through the plurality of inlet holes h1.

[0055] The heated air can be exhausted through the exhaust path to the cooking table 121. As the legs 1232 surround the first bent portion 1221, a gap G is generated between the concave portion of the legs 1232 and the exhaust port 122, and the heated air can be exhausted into the gap G.

[0056] According to the embodiment, due to the continuous inflow of heated air, the pressure in the gap may become relatively stronger than the pressure in the internal space of the upper container 120. Therefore, when the pressure exceeds a certain level, the heated air can be discharged from the gap to the internal space of the upper container 120. At this time, the gap G between the exhaust port 122 and the cover 123 is relatively narrow compared to the gap, so the flow rate of the air discharged through the gap G can be increased.

[0057] The direction of the heated air flowing into the upper container 120 through the hot air inlet 1000 may be toward the surface of the cooking table 121. That is, the flowing air can cause convection within the upper container 120 and circulate within the upper container 120. This allows the food to be cooked indirectly while being cooked quickly and evenly.

[0058] According to the embodiment, when a smoking agent is placed in the smoking section 112 of the lower container 110, the smoke generated by the smoking agent can flow into the upper container 120 through the plurality of inlet holes h1 and the gap G. This allows the aroma of smoke to be added to the food being cooked, and allows for easy and convenient preparation of smoked food at home.

[0059] According to the embodiment, when the far-infrared radiator 115 is disposed in the heating unit 111 of the lower container 110, far-infrared rays emitted from the far-infrared radiator 115 can flow into the upper container 120 through the plurality of inflow holes h1 and the gap G. This can remove the odor of the food to be cooked and discharge high-fat oil from the food to be cooked, thereby improving the taste and aroma.

[0060] The above is a specific example of implementing the present invention. The present invention includes not only the above-described examples, but also examples that can be easily modified by simple design changes or modifications. The present invention also includes techniques that can be easily implemented by modifying the examples. Therefore, the scope of the present invention should not be limited to the above-described examples, but should be defined by the claims below and their equivalents.
