    Description

    [Technical Field]



    [0001] The present disclosure relates to a vacuum low-temperature cooker, and more particularly, to a vacuum low-temperature cooker for vacuum-packaging and heating food.

    [Background Art]



    [0002] WO-A-2015/056284 discloses a combined machine for vacuum packaging and for cooking food at low temperature, comprising a structure which contains the functioning means of the machine and for supporting the control panel of the machine; the machine has a packaging section for packaging foods in vacuum bags or containers, which is combined with a cooking section of the foods that are just packaged in the packaging section.

    [0003] Furthermore, Sous Vide is a cooking method using low-temperature, and is a method partially developed in 1971 at Cuisine Solutions (a research institute involved in the development of the Sous Vide method for slow cooking food).

    [0004] The Sous Vide cooking method, allowing food to retain nutrients, texture, and moisture close to those of a precooked state, when cooked, is a method in which food contained in a vacuum packaging film is sealed under vacuum, and is then immersed in warm water to be heated over a long period of time at a relatively low temperature. In this case, while the temperature of water is maintained at a constant level, food is heated over a long period of time.

    [0005] A temperature of water heating the food varies, depending on a type of food to be cooked, but the temperature thereof is usually maintained at about 75°C. Since food is immersed in water of which a temperature is uniformly raised and maintained, an external surface and an interior of the food are uniformly heated, and the moisture content of the food can be maintained.

    [0006] However, in a case in which food is not reliably sealed and vacuum-packaged, a texture of food may be changed, nutrients may be destroyed, and a cooking state of food may be deteriorated. Thus, the step of vacuum-packaging food is a significantly important operation in the Sous Vide cooking method.

    [0007] Thus, after food is vacuum-packaged, the food should be immersed in water at a temperature uniformly raised and maintained. Thus, a user may perform the vacuum packaging of food and the heating of water.

    [Best Mode for Invention]



    [0028] FIG. 1 is a perspective view illustrating a vacuum low-temperature cooker according to an exemplary embodiment, FIG. 2 is a perspective view illustrating a main body fixed to an accommodation tub in the vacuum low-temperature cooker of FIG. 1, FIG. 3 is a front view illustrating a main body in the vacuum low-temperature cooker of FIG. 1, and FIG. 4 is an exploded perspective view illustrating a vacuum packaging unit in the vacuum low-temperature cooker of FIG. 1.

    [0029] Referring to the drawings, a vacuum low-temperature cooker of the present disclosure includes a main body 100, a vacuum packaging unit 200, and a control unit 300.

    [0030] Here, the main body 100 is provided with a heating unit 110 immersed in fluid 1 accommodated in an accommodation tub 10 and heating the fluid 1. In addition, the vacuum packaging unit 200 is a unit having a structure connected to the main body 100 and vacuum-sealing a packaging film. Moreover, the control unit 300 is a unit controlling the heating unit 110 and the vacuum packaging unit 200.

    [0031] In the vacuum low-temperature cooker of the present disclosure, the control unit 300 is installed in the main body 100.

    [0032] In other words, the control unit 300 is installed in the main body 100 as illustrated in the drawings. The control unit is installed in the main body 100 as long as the control unit serves to control all of the heating unit 110 and the vacuum packaging unit 200 as a single configuration.

    [0033] As a result, the vacuum low-temperature cooker of the present disclosure has a structure in which the main body 100 having the heating unit 110, and the vacuum packaging unit 200 are combined in one. In detail, all of the main body 100 having the heating unit 110, heating fluid 1 for low-temperature cooking, and the vacuum packaging unit 200, vacuum packaging food, are configured to be controlled by a single control unit 300, so vacuum low temperature cooking may be smoothly and conveniently performed, and manufacturing costs may be reduced and product costs may be lowered.

    [0034] Meanwhile, in the vacuum low-temperature cooker of the present disclosure, a vacuum pump VP providing air suction power to the vacuum packaging unit 200 is installed in the main body 100.

    [0035] In other words, the vacuum pump VP is installed in the main body 100 connected to the vacuum packaging unit 200 as illustrated in FIG. 1. The vacuum pump is installed in the main body 100 as long as the vacuum pump provides air suction power so as to suck air from a packaging film when the packaging film is vacuum-packaged in the vacuum packaging unit 200.

    [0036] In the present case the main body 100 and the vacuum packaging unit 200 are connected by a connection cable 400 so as to be in air and electrical communication with each other.

    [0037] Furthermore, the main body 100 may include a pressure sensor (not shown), electrically connected to the vacuum pump VP and the control unit 300, and measuring negative pressure of the vacuum pump VP so as to allow the control unit 300 to control an operation of the vacuum pump VP. When an interior of a packaging film is vacuumed after the vacuum pump VP is operated and a predetermined time has elapsed, and negative pressure of the vacuum pump VP, measured by the pressure sensor, is greater than a value, set in the control unit 300, an operation of the vacuum pump VP may be stopped by the control unit 300.

    [0038] For reference, in the main body 100, a discharge tube (not shown), connected to an air discharge port of the vacuum pump VP having been embedded, is connected to a lower end, thereby discharging air from the vacuum pump VP externally and discharging moisture, coming when air is sucked, externally.

    [0039] FIG. 5 is a bottom view illustrating an interior of a base portion in the vacuum packaging unit of FIG. 4, and FIG. 6 is an exploded perspective view illustrating a connection cable in the vacuum low-temperature cooker of FIG. 1.

    [0040] In addition, FIGS. 7 and 8 are a side view and a plan view illustrating the connection cable of FIG. 6, FIG. 9 is a cross-sectional view taken along line I-I' of FIG. 7, and FIG. 10 is a cross-sectional view taken along line II-II' of FIG. 8.

    [0041] When all of the control unit 300 and the vacuum pump VP are installed in the main body 100, as illustrated in FIG. 1, the main body 100 and the vacuum packaging unit 200 are connected by a connection cable 400.

    [0042] Here, the connection cable 400 has a structure connecting an external vacuum pump VP, providing air suction power, to a chamber portion 220 of the vacuum packaging unit 200 to be in air communication with each other, and connecting an external control unit 300, controlling while providing power, to a sealing unit 230 of the vacuum packaging unit 200 to be in electrical communication with each other.

    [0043] In detail, the connection cable 400 has an air line, allowing the vacuum pump VP to be in communication with the chamber portion 220, and an electric line, electrically connecting the control unit 300 to the sealing unit 230.

    [0044] In this case, as illustrated in the drawings, the vacuum pump VP and the control unit 300, disposed externally, are embedded in the main body 100 of the vacuum low-temperature cooker. For reference, the control unit 300 serves to control while providing power to the sealing unit 230 of the vacuum packaging unit 200, when the vacuum low-temperature cooker is connected to a power source by a power line 130.

    [0045] In addition, at least a portion of the electric line may be disposed in an air passage in the air line.

    [0046] As described above, the electric line is disposed in the air line, so the electric line may not be exposed externally to be protected. Furthermore, the connection cable 400 may have a simple link structure rather than a complex link structure.

    [0047] In detail, the air line includes an air plug 410 connected to an air end of the vacuum pump VP, an air connector 420 connected to the chamber portion 220 of the vacuum packaging unit 200, and an air hose 430 connecting the air plug 410 to the air connector 420.

    [0048] Here, the air plug 410 may have a plug structure to be connected to an air end of the main body 100 in communication with the vacuum pump VP disposed in the main body 100 of the vacuum low-temperature cooker.

    [0049] The air plug 410 may include a plug housing 411 into which the air hose 430 is inserted, an inner tube 412 disposed in the plug housing 411, and a housing cover 413 mounted on an opening 411b of the plug housing 411.

    [0050] In this case, in the plug housing 411, the air hose 430 is inserted into an interior through a connection hole 411a of one end, and the opening 411b may be formed in the other end.

    [0051] In addition, the inner tube 412 is disposed in the plug housing 411, one end thereof is connected to the air hose 430, and a first half-hole 412a may be formed in a side portion of the other end thereof.

    [0052] Moreover, the housing cover 413 may be mounted on the opening 411b to cover the opening 411b of the plug housing 411.

    [0053] In addition, the electric line includes an electric plug pin 480 mounted on the air plug 410, and an electric wire 490 connected to the electric plug pin 480.

    [0054] Here, the electric plug pin 480 is formed to be connected to the electricity end of the control unit 300, that is, the electricity end formed to be electrically connected to the control unit 300 in the main body 100.

    [0055] In addition, the electric wire 490 is passing through and disposed in the air connector 420 and the air hose 430, one end thereof is connected to the sealing unit 230 of the vacuum packaging unit 200, and the other end thereof is connected to the electric plug pin 480. For reference, the electric wire may be electrically connected to a hot wire 231 of the sealing unit 230.

    [0056] In detail, the electric plug pin 480 is mounted to pass through the housing cover 413, one end thereof is disposed inwardly of the plug housing 411, and the other end thereof is disposed outwardly of the plug housing 411.

    [0057] Moreover, the housing cover 413 of the air plug 410 may include an air tube 414 passing through and extended outwardly of the plug housing 411 while being connected to the inner tube 412. An O-ring 414b may be configured to surround an outer circumferential surface of the air tube 414.

    [0058] In this case, as the other end of the inner tube 412 is inserted into and connected to an end of the air tube 414 inwardly of the plug housing 411, a second half-hole 414a is combined with the first half-hole 412a and is forming an outlet of the electric wire 490, so the electric wire 490 is coming out of the outlet while bent in a lateral direction to be connected to one end of the electric plug pin 480.

    [0059] In this case, as illustrated in FIG. 1, when the vacuum pump VP and the control unit 300, respectively externally disposed, are embedded in the main body 100 of the vacuum low-temperature cooker, the air end and the electricity end may be configured in a socket S formed in an outer housing 120 of the main body 100 of the vacuum low-temperature cooker by way of example.

    [0060] In detail, an air end of the vacuum pump VP, that is, an end, which is connected to the vacuum pump VP in the main body 100 and into which air is sucked, is a through tube P of the socket S, and an electricity end of the control unit 300, that is, an end, which is connected to the control unit 300 in the main body 100 and to which power is provided, is a terminal T of the socket S. For reference, the terminal T is electrically connected to a control processing unit 330 in the control unit 300.

    [0061] Meanwhile, the air connector 420 is mounted in a base member 210 of the vacuum packaging unit 200.

    [0062] The air connector 420 may include a first branch tube 421 to which the air hose 430 is connected, a second branch tube 422 connected to the chamber portion 220 by a link tube 429, a third branch tube 423 provided with the electric wire 490 disposed therein and passing therethrough, and a hub tube 424 connecting the first branch tube 421, the second branch tube 422, and the third branch tube 423. For reference, air, sucked through an air suction hole 220a of the chamber portion 220, moves through the link tube 429 to an air hose 430.

    [0063] Here, the electric wire 490 passes through the hub tube 424 and the third branch tube 423 from the air hose 430 to be extended and disposed.

    [0064] Moreover, a stopper 425 may be mounted on an end of the third branch tube 423, and the stopper 425 may be provided with a line hole 425a with the electric wire 490 disposed therein and passing therethrough not to allow air to pass therethrough and to only allow the electric wire 490 to pass therethrough. In this case, the line hole 425a provided with the electric wire 490 disposed therein and passing therethrough is processed to be sealed not to allow air to come in and out.

    [0065] Moreover, although not illustrated in the drawings, the electric line may have a structure in which at least a portion thereof is attached to an external surface of an air line or is disposed in an outer cover of the air line, and furthermore may have a structure arrangement arranged such that the electric line is arranged separately from the air line.

    [0067] First, the heating unit 110 may include an inner housing 111, a heater 112, a stirring member 113, and a sensor 114.

    [0068] Here, the inner housing 111 is a portion immersed in fluid 1 of the accommodation tub 10, and a through hole 111a may be formed therein to allow fluid 1 to pass therethrough. Moreover, a level limit line 111b, indicating appropriate upper and lower limits for cooking, with respect to a level of the fluid 1 accommodated in the accommodation tub 10, may be formed in an external surface of the inner housing 111.

    [0069] In addition, the heater 112 is embedded in the inner housing 111 and heats fluid 1, and a heating bar, disposed in a vertical direction as illustrated in the drawings, may be used by way of example. The heating bar is in contact with the fluid 1 and is then heat-exchanged, thereby heating the fluid 1.

    [0070] Moreover, the stirring member 113 is embedded in the inner housing 111 and allows fluid 1 to flow so as to allow the fluid 1 to pass through the inner housing 111 through a through hole, and a rotating fan, rotated by a motor as illustrated in the drawings, may be used by way of example.

    [0071] In addition, the sensor 114 is mounted on the inner housing 111 and measures a temperature of fluid 1, and a thermocouple may be used by way of example.

    [0072] In this case, the heater 112, the stirring member 113, and the sensor 114, described previously, are electrically connected to the control unit 300, so power is provided and driving is controlled. Moreover, while a real time temperature of the fluid 1 is measured, the fluid may be heated to a set temperature and may be maintained.

    [0073] Moreover, the vacuum packaging unit 200 may include a base member 210 connected to the main body 100, as well as a chamber portion 220, a sealing unit 230, and a cover member 240, mounted on the base member 210.

    [0074] Here, the chamber portion 220 is provided with an air suction hole 220a sucking air from a packaging film. Thus, when the packaging film is seated thereon, air in the packaging film is sucked through an opening of the packaging film to be vacuumed.

    [0075] In addition, the sealing unit 230 is a unit heat-sealing the packaging film, and a hot wire 231 heating and pressing a portion of the packaging film, in which an opening is formed, is mounted thereon.

    [0076] Moreover, the cover member 240 is configured to cover the chamber portion 220 and the sealing unit 230 with the packaging film interposed between the cover member, and the chamber portion and the sealing unit, and may serve to press the packaging film while covering the packaging film from the top, when the portion of the packaging film, in which the opening is formed, is seated on the base member 210 to be disposed over the chamber portion 220 and the sealing unit 230.

    [0077] Meanwhile, the control unit 300 may include an input unit 310, a display unit 320, and a control processing unit 330.

    [0078] Here, the input unit 310 is a unit into which a control command is input to control the heating unit 110 and the vacuum packaging unit 200, the display unit 320 is a unit displaying an input display of the input unit 310 and a state display of the heating unit 110 and the vacuum packaging unit 200, and the control processing unit 330, a unit processing the control command input through the input unit 310, may be a printed circuit board (PCB) or a microprocessor. For reference, reference numeral 130 in FIG. 1 may be a power line, to which power of the vacuum low-temperature cooker of the present disclosure is provided.

    [0079] In the vacuum low-temperature cooker of the present disclosure, a specific shape of the main body 100 will be described below.

    [0080] The main body 100 may include an inner housing 111 and an outer housing 120. Here, the inner housing 111 is provided with the heating unit 110 mounted thereon, and is disposed inwardly of the accommodation tub 10 in a plan view.

In this case, the outer housing 120 may be provided with the vacuum pump VP and the control unit 300, mounted thereon.

    [0081] Thus, a side wall 11 of the accommodation tub 10 is disposed between the heating unit 110 and the outer housing, so direct thermal influence of the heating unit 110 on the control unit 300 and the vacuum pump VP may be significantly reduced and direct thermal influence from fluid 1 heated by the heating unit 110 may be significantly reduced. Thus, the control unit 300 and the vacuum pump VP may be prevented from malfunctioning or being damaged due to heat.

    [0082] In detail, the inner housing 111 and the outer housing 120 are disposed to be parallel in a vertical direction, and are disposed to be connected to each other in a "∩" shape in which a stop groove 100a is disposed in a lower portion, so the side wall 11 of the accommodation tub 10 is inserted into the stop groove 100a to allow the main body 100 to be caught in the accommodation tub 10. Thus, the main body 100 may have a structure stably caught in the accommodation tub 10. Moreover, an exhaust port 190 exhausting heat of an interior may be formed in an upper joint.

    [0083] In addition, in the outer housing 120, a clamp 121 pressing the side wall 11 of the accommodation tub 10 is mounted thereon, so a position of the main body 100 may be fixed to the accommodation tub 10.

    [0084] Furthermore, as another exemplary embodiment, as illustrated in FIG. 14, the main body 100 may include a single housing H disposed inwardly of the accommodation tub 10 in a plan view, and a heating unit 110, a vacuum pump VP, as well as a control unit 300 may be mounted in the housing H.

    [0085] Here, components, designated by reference numerals having not been described, have already been described above and therefore will not be described.

    [0086] FIGS. 11 through 13 are drawings illustrating an exemplary embodiment with respect to a detachable structure and an integrated structure of a stand and a vacuum packaging unit in a vacuum low-temperature cooker of the present disclosure.

    [0087] Referring to the drawings, the vacuum low-temperature cooker of the present disclosure may further include a stand 510 on which the main body 100, described previously, is mounted.

    [0088] In addition, the stand 510 or the vacuum packaging unit 200 may be provided with a support bracket portion 520 configured to allow the stand and the vacuum packaging unit to be removably attachable to each other.

    [0089] In other words, as illustrated in FIG. 11, the support bracket portion 520 is formed in the stand 510, so the vacuum packaging unit 200 is able to be assembled in the support bracket portion 520 to be removably attached to the stand 510. Moreover, as another example, as illustrated in FIG. 12, the support bracket portion 520 is formed in the vacuum packaging unit 200, so the stand 510 is able to be assembled in the support bracket portion 520 to be removably attached to vacuum packaging unit 200.

    [0090] In addition, as another example, as illustrated in FIG. 13, the stand 510 may be integrally configured with the vacuum packaging unit 200.

    [0091] Furthermore, as another example, although not illustrated in the drawings, the stand 510 or the support bracket portion 520 is provided with a connection cable embedded therein. The main body 100 and the vacuum packaging unit 200 are in air and electrical communication with each other by a connection cable, when being fastened to a terminal of a connection cable of the stand 510 or the support bracket portion 520, having been exposed. In other words, a connection cable is configured in the stand 510 or the support bracket portion 520 while not being exposed externally, and only a terminal is configured to be exposed to an external surface of the stand 510 or the support bracket portion 520. Thus, the main body 100 and the vacuum packaging unit 200 are in air and electrical communication with each other, when being fastened to a terminal of a connection cable in the stand 510 or the support bracket portion 520.

    [0092] As a result, as described previously, the vacuum low-temperature cooker of the present disclosure has a structure in which the main body 100, having the heating unit 110, and the vacuum packaging unit 200 are combined in one. In further detail, all of the main body 100, having the heating unit 110 heating fluid 1 for low-temperature cooking, and the vacuum packaging unit 200, vacuum packaging food, are configured to be controlled by a single control unit 300. Thus, vacuum low temperature cooking may be smoothly and conveniently performed, and manufacturing costs may be reduced and product costs may be lowered.
