Description

Technology Field

[0001] The present invention relates to an automatic cooking device, and more specifically, to an automatic cooking device that performs uniform cooking through heating and rotary stirring of food ingredients under set conditions, thereby achieving consistent quality and taste, promoting mass production, and expecting cost reduction effects through the replacement of labor. In particular, it relates to an automatic cooking device that maximizes user convenience and hygiene management efficiency by fully automating the cleaning of cooking containers, minimizes the radius of rotation when rotating cooking containers for stirring ingredients, and minimizes volume by configuring a compact structure. Background Technology

[0002] General food preparation refers to the process of placing ingredients into a cooking vessel, such as a frying pan or a pot, and then heating and stirring them for a certain period of time to properly cook and complete the dish. Although it varies depending on the ingredients, for most ingredients, once cooking begins, the act of continuously stirring the ingredients must be performed so that they do not stick to the cooking vessel or burn, and are cooked evenly.

[0003] Therefore, it is natural that the process of cooking ingredients requires a significant amount of labor, and since achieving and maintaining a consistent taste necessitates relying solely on cooks with a high level of skill and experience in handling cooking vessels or tools, it can be said that the food industry as a whole has a relatively high dependence on labor.

[0004] Consequently, the automation of cooking operations is advancing in the food industry due to various factors such as securing cooks, maintaining cooking skills, and improving cooking environments, and the technological development of automated cooking devices to facilitate this automation is actively underway.

[0005] For example, a conventional automatic cooking device may be exemplified by including a deep pot capable of rotating and stirring for cooking, an induction heating plate positioned adjacently across the outer wall of the deep pot, and a driving device that causes the ingredients inside the pot to be cooked while being evenly stirred as the deep pot is rotated.

[0006] In other words, when ingredients are placed inside the pot, they mix evenly, allowing cooking to take place automatically for a set period of time under set temperature conditions.

[0007] However, conventional automatic cooking devices were accompanied by the inconvenience that, in order to cook different types of food in the pot, a cook had to be present to manually clean the inside of the pot at the time cooking was finished. Prior art literature

[0017] To fully understand the present invention, preferred embodiments of the invention are described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0018] The automatic cooking device according to the present invention can be broadly defined as comprising a base part (10), a support part (20), a cooking part (100), and a washing part (200).

[0019] First, the base part (10) constitutes the bottom part of the automatic cooking device according to the present invention and contains a controller for overall driving control of the cooking part (100), support part (20), washing part (200), etc., various electrical devices for power supply, and pipes for supplying and draining washing water.

[0020] For example, the base portion (10) may be exemplified as including a base housing (11) in which a drainage groove (12) is recessed to a certain depth in the central part of the upper surface in the shape of a housing, and a drain hole (13) for draining washing water flowing into the drainage groove (12) is formed on one side of the drainage groove (12), and a container support plate (14) installed on the upper surface of the base housing (11) on which a container for portioning cooked food is placed.

[0021] The base housing (11) forms the exterior of the base part (10) and may be provided with a control button for operating the cooking part (100), support part (20), washing part (200), etc., which will be described later, and a display window for displaying the current temperature of the cooking part (100), cooking status, etc. on the front.

[0022] The drainage groove (12) formed in the center of the upper surface of the base housing (11) can be implemented in the form of a groove that is recessed to a certain depth, and at this time, the lower surface of the drainage groove (12) is formed with a sloping gradient toward the drain (13) to induce natural drainage of the washing water toward the drain (13) by its own weight.

[0023] The drain (13) can be implemented in the form of a hole perforated on one side of the drainage groove (12), and although not shown, a sewage pipe placed inside the base housing (11) is directly connected to the drain (13) so that the washing water drained through the drain (13) can be continuously drained.

[0024] The container support plate (14) is rotatably coupled to the upper surface of the base housing (11) and rotates around the cooking unit (100) as cooking is completed, thereby moving the container and allowing the food discharged from the cooking unit (100) to be easily transferred into the container.

[0025] Next, the support member (20) is installed on the base member (10) and is responsible for supporting and driving the cooking unit (100) so that it can rotate in place while being supported at a certain height above the base member (10).

[0026] A pair of support members (20) can be installed upright at a certain height toward the top from the left and right corners of the base member (10), and a cooking unit (100) can be connected between the pair of support members (20) thus provided.

[0027] Each support member (20) may be exemplified by comprising a support housing (21) having a hollow tube structure that forms the exterior of the support member (20), a support block (22) that is embedded in the support housing (21) and can be adjusted in height along the longitudinal direction of the support housing (21) and fixed at a desired position, and a support motor (23) connected to the side of the cooking unit (100) while coupled to the support block (22).

[0028] The support motor (23) may be a stepper motor capable of forward and reverse rotational driving, and the cooking unit (100) connected to this support motor (23) can be tilted at a certain angle during the cooking process of the ingredients, and additionally, as cooking is completed, tilt adjustment for discharge by the weight of the food inside, and can be rotated to be upside down to facilitate internal cleaning through the cleaning unit (200) to be described later.

[0029] Next, the cooking unit (100) is configured to have a cylindrical structure with an open opening that accommodates food to be cooked inside and performs the function of heating and cooking the accommodated food while rotating it, and has a structure connected to a support motor (23) of a support unit (20) that is installed upright on both the left and right sides and spaced apart at a certain height above the base unit (10).

[0030] As the cooking unit (100) is connected to the support unit (20), it can rotate in place with the support motor (23) of the support unit (20) as the rotation axis, and at the same time, rotate so that the material contained inside can be evenly stirred and cooked.

[0031] Therefore, it should be noted that the term "rotation of the cooking unit (100)" is explained in a mixed sense, including the rotation of the entire cooking unit (100) with the support motor (23) as the rotation axis and the rotation of only the material contained within the cooking unit (100).

[0032] More specifically, the cooking unit (100) can be exemplified as including an outer housing (110), an inner housing (120), a heater module (130), a first rotary drive module (140), and a cooking container (150).

[0033] The outer housing (110) forms the outermost exterior of the cooking unit (100) in the shape of a tube with an open top, and a connector (111) connected to the support motor (23) of the support unit (20) may be provided near the center of both left and right sides.

[0034] That is, the structure is such that the support motor (23) is connected to the middle point of the cooking unit (100) approximately, and the rotation radius of the cooking unit (100) can be minimized when rotating with the support motor (23) as the rotation axis, and accordingly, the advantageous effect of making the overall appearance of the automatic cooking device more compact can be expected.

[0035] Additionally, a plurality of first guide rollers (112) may be mounted at equal intervals along the circumferential direction on the upper inner surface of the outer housing (110), and each first guide roller (112) may rollably contact the outer circumferential surface of the cooking container (150) to be described later, thereby reducing rotational friction resistance with the cooking container (150) and promoting stable rotation of the cooking container (150) in place.

[0036] Next, the inner housing (120) is formed in the shape of a tube with an open top, similar to the outer housing (110), and is inserted and installed inside the outer housing (110), and the heater module (130) is fixedly supported on the inner side.

[0037] While the outer housing (110) has a roughly square housing structure, the inner housing (120) has a cylindrical structure that is inscribed within the outer housing (110), and the lower part is implemented in a roughly spherical shape.

[0038] Accordingly, the exterior of the cooking unit (100) is composed of two layers, an outer housing (110) and an inner housing (120), which can improve the overall thermal insulation performance of the cooking unit (100). Additionally, an air insulation effect can be expected due to the structure in which a certain amount of empty space is formed in the lower and corner portions between the outer housing (110) and the inner housing (120), thereby more effectively suppressing heat dissipation from the outside of the cooking unit (100) and improving stability.

[0039] Again, a heater installation groove (121) may be formed in a certain portion of the inner surface of the inner housing (120), and a heater module (130) is placed in this heater installation groove (121).

[0040] A certain area of ​​installation opening (122) may be formed open in the lower central part of the inner housing (120), and a first rotary drive module (140) may be provided so as to be exposed to the inside of the inner housing (120) through the installation opening (122).

[0041] The heater module (130) is fixedly installed in a heater installation groove (121) formed on the inner side of the inner housing (120) and serves as a heat source for heating the cooking container (150).

[0042] The heater module (130) can be implemented as an induction coil, and the cooking vessel (150) can be heated by induction heating the cooking vessel (150) by including a magnetic material, thereby heating the cooking vessel (150) to cook the material inside the cooking vessel (150).

[0043] Next, the first rotary drive module (140) is configured to provide rotational power for rotating the cooking vessel (150) and is installed at the center of the lower part of the outer housing (110), having a structure that is exposed into the inner housing (120) through an installation hole (122) formed in the inner housing (120), while the cooking vessel (150) is installed inside the inner housing (120) in a cylindrical shape with an open top, and the center of the lower part is connected to the first rotary drive module (140), and the upper outer edge surface is rotatably contacted and supported by the plurality of first guide rollers (112).

[0044] Accordingly, when the first rotary drive module (140) is operated, the cooking container (150) can rotate in place inside the inner housing (120) with the first rotary drive module (140) as the rotation axis, and heat cooking can be performed while rotating the material introduced into the interior.

[0045] At this time, a stirring blade (151) may be formed protruding to a certain height on the inner side of the cooking container (150) so as to scoop up the material contained inside and perform a stirring action when the cooking container (150) rotates in place.

[0046] The first rotary drive module (140) is structured to be completely embedded inside the outer housing (110) and is not exposed to the outside, thereby allowing the exterior of the cooking unit (100) to be configured more compactly and preventing unnecessary volume increase.

[0047] In one embodiment, the first rotary drive module (140) may be exemplified as comprising a motor housing (141), a space block (142), a first rotary drive motor (143), and a rotor plate (144).

[0048] The motor housing (141) is fixedly installed on the outer housing (110) and has a hollow housing shape and accommodates the first rotary drive motor (143) inside.

[0049] The motor housing (141) serves to shield heat transmitted from the heater module (130) to prevent unnecessary heat from being transmitted to the first rotary drive motor (143) housed inside, and a ventilation opening (141a) is formed through the bottom surface so that heat generated by the operation of the first rotary drive motor (143) can be discharged to the outside through the ventilation opening (141a).

[0050] Although not shown, a through hole may be formed in the center of the upper surface of the motor housing (141) for the rotation axis (143a) of the first rotary drive motor (143) to pass through.

[0051] The space block (142) is installed in the center of the upper surface of the motor housing (141), and although not shown, a communication hole may be formed vertically through the center of the space block (142) that communicates with the through hole formed through the center of the upper surface of the motor housing (141).

[0052] That is, the rotation axis (143a) of the first rotary drive motor (143) installed inside the motor housing (141) is structured to be exposed to the center of the space block (142) by penetrating the upper surface of the motor housing (141) and the space block (142), and a rotor plate (144) can be coupled to the rotation axis (143a) of the first rotary drive motor (143) exposed in this way.

[0053] The first rotary drive motor (143) can be covered by the motor housing (141) first, and then covered by the space block (142) in the direction of the heater module (130), thereby having a structure that can more effectively shield the heat transmitted from the heater module (130).

[0054] The rotor plate (144) is a thin plate structure that is spaced apart at a certain height above the space block (142) and is directly connected to the rotation shaft (143a) of the first rotary drive motor (143) exposed to the space block (142), and is connected to the lower surface of the cooking container (150) facing upward, thereby performing the function of transmitting the rotational driving force of the first rotary drive motor (143) to the cooking container (150).

[0055] At this time, a pair of second guide rollers (141b) are installed on the upper surface of the motor housing (141) with the space block (142) in between, so as to be able to support the lower surface of the cooking container (150) so as to be able to roll.

[0056] That is, when the cooking container (150) rotates in place by the first rotary drive motor (143), the bottom of the cooking container (150) is supported by the second guide roller (141b) and the top is aligned with the first guide roller (112), so that a structure can be provided to rotate more stably.

[0058] Next, the washing unit (200) is configured to perform the function of washing the inside of the cooking container (150) by spraying washing water toward the inside of the cooking container (150), so that automatic washing can be performed sequentially immediately after the cooked food is discharged from the cooking container (150) without the need to disassemble and wash the cooking container (150) separately.

[0059] The washing unit (200) is installed in the base unit (10) which is directly below the cooking container (150) and can spray washing water toward the cooking container (150). Preferably, if the open opening of the cooking unit (100) is rotated and positioned to face the base unit (10), washing water can be sprayed toward the inside of the cooking unit (100) to cleanly wash away any remaining material residue inside the cooking container (150) of the cooking unit (100).

[0060] At this time, foreign substances and wastewater generated during the cleaning process can fall freely into the drainage groove (12) of the base housing (11) and then be discharged through the drain (13).

[0061] In one embodiment, the washing unit (200) may be exemplified by including a nozzle housing (220) formed protruding from a drainage groove (12) and a nozzle member (210) installed in the nozzle housing (220) and spraying washing water toward the inner surface of a cooking vessel (150) that has been rotated and moved.

[0062] At this time, the cooking vessel (150) rotated toward the nozzle member (210) may mean an inverted state in which the open top of the cooking vessel (150) faces downward.

[0063] The nozzle housing (220) can support a plurality of nozzle members (210), and each nozzle member (210) has a structure that is connected to a washing water supply source through a separate pipe (not shown) to receive and spray high-pressure washing water.

[0064] Each nozzle member (210) continuously sprays cleaning water toward the inner surface of the cooking vessel (150), while the cooking vessel (150) rotates in place by the first rotary drive motor (143), so that even if the nozzle member (210) sprays cleaning water in one direction, the inner surface of the cooking vessel (150) is evenly exposed to the sprayed cleaning water and cleaning can be performed.

[0066] It should be noted that in describing various embodiments of the washing unit (200) below, the same reference numerals are used for different components.

[0067] In another embodiment of the washing unit (200), the washing unit (200) may be exemplified as including an angle adjustment motor (230) installed in a drainage groove (12) as shown in FIG. 12, a nozzle housing (220) coupled to the angle adjustment motor (230) and rotated in the drainage groove (12) by the angle adjustment motor (230) to adjust the installation angle, and a nozzle member (210) installed in the nozzle housing (220) and spraying washing water toward the inner surface of a cooking vessel (150) that has been rotated and moved.

[0068] The nozzle members (210) coupled to the nozzle housing (220) have a determined spraying direction, and as the nozzle housing (220) itself rotates and moves over the drainage groove (12) by the angle adjustment motor (230), the spraying direction of the nozzle members (210) can be adjusted to follow this.

[0069] The nozzle housing (220) is formed in a roughly fan-shaped structure, and the nozzle member (210) is coupled to the arc portion of the nozzle housing (220) to spray cleaning water radially.

[0070] At this time, as the end of the nozzle housing (220) is connected to the angle adjustment motor (230), the nozzle housing (220) itself can rotate and move at a certain angle in the drainage groove (12) to adjust the spray angle of the cleaning water.

[0071] For example, as shown in FIG. 12a, if the nozzle member (210) is positioned toward the inner surface of the cooking container (150), the washing water can be sprayed toward the inner surface of the cooking container (150).

[0072] Conversely, as shown in FIG. 12b, if the nozzle housing (220) is rotated in the opposite direction shown in FIG. 12a, the cleaning water can be sprayed upward on the slope of the drainage groove (12). In this case, the cleaning water moves from the high place to the low place of the drainage groove (12) by its own weight and sweeps down foreign matter on the surface of the drainage groove (12), thereby preventing foreign matter from accumulating in the drainage groove (12).

[0074] As another embodiment of the washing unit (200), the washing unit (200) may be exemplified as including a nozzle member (210) that is installed in a drainage groove (12) so as to be rotatable in place as shown in FIG. 13 and sprays washing water toward the inner surface of a cooking vessel (150) that has been rotated and moved, and a nozzle driving motor (220) connected to the nozzle member (210) and operating the nozzle member (210) in forward and reverse directions.

[0075] In this embodiment, the nozzle member (210) adopts a structure capable of directly spraying cleaning water not only onto the inner surface of the cooking container (150) but also onto the surface of the drainage groove (12), thereby allowing the area around the drainage groove (12), which is highly susceptible to contamination, to be managed more cleanly by accommodating various foreign substances discharged from inside the cooking container (150) as well as the cooking container (150) that must be cleaned during the cleaning process of the cooking container (150).

[0076] To this end, the nozzle member (210) can be exemplified as including a coupling shaft (211) and a nozzle body (212).

[0077] The connecting shaft (211) has a shaft-type configuration that penetrates the drainage groove (12), with the upper end exposed outside the drainage groove (12) and the lower end extended into the base housing (11) and connected to the nozzle drive motor (220) installed inside the base housing (11).

[0078] The nozzle drive motor (220) is installed at a certain distance eccentric from the coupling shaft (211) and can transmit rotational power to the coupling shaft (211) through a power transmission means such as a belt, and although not indicated by a separate drawing reference, an insertion hole is formed through the drainage groove (12) for the coupling shaft (211) to be inserted through, and a bearing can be installed in this insertion hole to support the coupling shaft (211) so that it can rotate in place.

[0079] A pipe for supplying washing water may be routed into the interior of the coupling shaft (211), and a swivel coupling (211a) is applied to the bottom of the coupling shaft (211) so that the internal pipe does not twist when the coupling shaft (211) rotates in the forward and reverse directions, thereby preventing the internal pipe from twisting even when the coupling shaft (211) rotates repeatedly.

[0080] The nozzle body (212) is installed at the top of the coupling shaft (211) and performs the function of spraying cleaning water around it while rotating in place according to the rotational operation of the coupling shaft (211).

[0081] At this time, the nozzle body (212) may be provided with an upward spray nozzle (212a) that guides and sprays washing water, which is pressurized from the direction of the coupling shaft (211), in an upward diagonal direction toward the inner circumference of the cooking container (150), a downward spray nozzle (212b) that guides and sprays washing water in a downward diagonal direction toward the surface of the drainage groove (12), and a vertical spray nozzle (212c) that guides and sprays washing water directly upward toward the inner bottom surface of the cooking container (150).

[0082] That is, the nozzle body (212) is structured to rotate in place and simultaneously spray cleaning water in three different directions, and the cooking container (150) and the drainage groove (12) are simultaneously cleaned by the sprayed cleaning water, so that the drainage groove (12), where foreign matter is easily left behind and accumulated, can always be kept clean without separate regular cleaning.

[0083] As the upward spray nozzle (212a), downward spray nozzle (212b) and vertical spray nozzle (212c) are structured to branch out radially from inside the nozzle body (212), the cleaning water pumped from inside the coupling shaft (211) flows into the center of the nozzle body (212) and is then distributed to each of the branched upward spray nozzle (212a), downward spray nozzle (212b), and vertical spray nozzle (212c) and discharged outward from the nozzle body (212).

[0084] The embodiments of the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom. Therefore, it will be understood that the present invention is not limited only to the forms mentioned in the detailed description above. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and substitutions within the spirit and scope of the present invention as defined by the appended claims.
