[0015] 1 and 2. Fig. 1 is a front perspective view of a food cooking apparatus according to an embodiment of the present invention, and Fig. 2 is a rear perspective view of a food cooking apparatus according to an embodiment of the present invention.

[0016] Food preparation apparatus 100 is configured to generate hot water and steam for cooking food ingredients. In some embodiments, food preparation apparatus 100 includes a case 200. Case 200 is provided with an inlet 210 (FIG. 1) and an exhaust vent 220 (FIG. 2), and inlet 210 may be provided with a door (not shown).

[0017] Inlet 210 allows a user to load or remove cooking container 700 from food preparation apparatus 100. Exhaust vent 220 in Figure 2 allows hot air or steam generated during cooking or cleaning to be removed from food preparation apparatus 100.

[0018] In some embodiments, food preparation apparatus 100 further includes a drain tray 300 below the Y direction of case 200. Drain tray 300 is used to direct excess moisture generated after cooking for subsequent processing.

[0019] In some embodiments, food preparation appliance 100 further includes a user control interface (not shown), which may be located within case 200 or may be an external control interface located outside case 200.

[0020] Please refer to Figure 3. Figure 3 is a system block diagram of a food preparation apparatus 100 according to an embodiment of the present invention. Solid line connections between blocks represent paths for liquid water or steam, and dotted line connections between blocks represent paths for electrical connections.

[0021] In some embodiments, food preparation apparatus 100 includes a steam generating device 400 , a hot water generating device 500 , a cooking area 600 , and a control component 800 .

[0022] The steam generating device 400 is used to generate steam when driven. The hot water generating device 500 generates hot water when driven. The cooking area 600 has a cooking space 710.

[0023] The control component 800 is connected to the steam generating device 400, the hot water generating device 500, and the cooking area 600. When activated, the control component 800 is used to perform a multi-stage cooking process (described in more detail below).

[0024] Please continue to refer to Figure 3. In some embodiments, the steam generating device 400 includes a steam storage tank 410 and a first heater 420, and the volume of liquid water in the steam storage tank 410 is less than ¼ of the total volume of the steam storage tank 410, so that the first heater 420 can rapidly heat the liquid water to a boiling point to improve the steam generation efficiency of the steam generating device 400.

[0025] The volume of liquid water in steam storage tank 410 is less than one-quarter of the total volume of steam storage tank 410, and more specifically, the total volume of steam storage tank 410 is approximately 1 liter. Therefore, the volume of liquid water is preferably approximately 250 ml.

[0026] In some embodiments, the steam generating device 400 is a steam boiler. In some embodiments, the steam storage tank 410 is connected to a steam pipe 831 of a pipeline component 830 of the control component 800 (described in more detail below), thereby outputting steam from the steam storage tank 410 via the steam pipe 831.

[0027] In this embodiment, the first heater 420 is electrically connected to a controller 810 of the control component 800 (described in more detail below). Thus, the controller 810 can control the first heater 420 to heat and prepare steam as needed. In some embodiments, the steam generating device 400 includes a first steam outlet 430, and the steam generating device 400 is used to output steam to a steam pipe 831 through the first steam outlet 430.

[0028] Please continue to refer to Figure 3. In some embodiments, the hot water generating device 500 includes a hot water tank 510 and a second heater 520. Because the hot water generating device 500 does not need to generate steam, the second heater 520 does not need to heat liquid water to a boiling point, thereby saving energy required for the hot water generating device 500 to generate hot water.

[0029] In this embodiment, the hot water generating device 500 is a hot water boiler. In some embodiments, the hot water tank 510 is connected to a water pipe 833 of a pipeline component 830 of the control component 800 (described in more detail below), and hot water from the water tank 510 is output via the water pipe 833.

[0030] In some embodiments, the second heater 520 is electrically connected to a controller 810 of the control component 800 (described in more detail below). Thus, the controller 810 can control the second heater 520 to heat and prepare hot water as needed.

[0031] In this embodiment, the hot water generating device 500 includes a hot water outlet 530, and the hot water generating device 500 is configured to output steam through the hot water outlet 530.

[0032] In some embodiments, food preparation apparatus 100 can perform a preparation process in which control component 800 controls first heater 420 to heat water above its boiling point to generate steam, which is then stored in steam storage tank 410.

[0033] The control component 800 also controls the second heater 520 to heat water below the boiling point to produce hot water, which is stored in the hot water tank 510 .

[0034] The following description will be made with reference to Figures 4 and 5. Here, Figure 4 is a side view of the interior of a food cooking apparatus according to an embodiment of the present invention, viewed from a first angle, and Figure 5 is a side view of the interior of a food cooking apparatus according to an embodiment of the present invention, viewed from a second angle.

[0035] 4 in the X direction is a space defined by the cooking vessel 700, i.e., the cooking vessel 700 can accommodate an object. Thus, different cooking vessels 700 define different cooking spaces 710.

[0036] In this embodiment, the cooking area 600 has a fixture 610 (FIGS. 7-10, described below) that allows a user to conveniently position the cooking vessel 700 in a precise location within the cooking area 600.

[0037] In some embodiments, the fastening portion 610 defines an arc, such that the outer shape of the cooking vessel 700 can match the fastening portion 610. However, the fastening portion 610 can be formed in other shapes for use with different cooking vessels 700.

[0038] 6 and 7. Fig. 6 is a top view of the interior of food cooking apparatus 100 according to an embodiment of the present invention. Fig. 7 is a partially enlarged view showing the detailed structure of injection head 840 of food cooking apparatus 100 according to an embodiment of the present invention.

[0039] In some embodiments, the control component 800 includes a jet head 840, a drive component 820, a pipeline component 830, and a controller 810. The jet head 840 has a jet orifice 841 as shown in FIG.

[0040] The drive component 820, when actuated, is used to operate the jet head 840 to selectively position the jets 841 in and out of the cooking space 710.

[0041] When activated, the pipeline component 830 selectively connects the steam generating device 400 to the cooking area 600 and connects the hot water generating device 500 to the cooking area 600. The controller 810 is used to drive the various components when activated.

[0042] Continuing from the previous paragraph, in some embodiments, when the controller 810 is activated, the controller 810 is used to drive the drive component 820 to operate the injection head 840 so that the injection nozzle 841 is positioned within the cooking space 710.

[0043] The pipeline component 830 is actuated to communicate with the steam generating device 400 and the jet 841 for a first predetermined steam time.

[0044] The pipeline component 830 is driven to connect the hot water generating device 500 and the outlet 841 until the first predetermined amount of hot water is injected into the cooking space 710.

[0045] During the second predetermined steam time, the pipeline component 830 is driven to connect the steam generating device 400 to the nozzle 841, and the pipeline component 830 is driven to connect the hot water generating device 500 to the nozzle 841 until a second predetermined amount of hot water is injected into the cooking space 710.

[0046] In some embodiments, jets 841 are one or more terminal jets, such as the openings on the downward-facing surface of jet head 840 in Figure 7. In some embodiments, jets 841 are bifurcated jets, such as the openings on the side of jet head 840 in Figure 7. In some embodiments, jets 841 include both terminal jets and bifurcated jets. Furthermore, jets 841 may be the same size or different sizes.

[0047] 4 and 5. In this embodiment, the pipeline components 830 include a steam pipe 831, an air valve 832, a water pipe 833, a water valve 834, and a three-way pipe 835.

[0048] The steam pipe 831 is connected to the steam generating device 400. The steam pipe 831 is provided to an air valve 832, and the controller 810 is electrically connected to the air valve 832.

[0049] The water pipe 833 is connected to the hot water generating device 500. A water valve 834 is provided on the water pipe 833, and the controller 810 is electrically connected to the water valve 834.

[0050] The three-way pipe 835 is connected to the steam pipe 831, the water pipe 833, and the injection head 840. The air valve 832 and the water valve 834 are controlled by the controller 810 to allow or prohibit steam from the steam generating device 400, and the hot water from the hot water generating device 500 is sent to the injection head 840 and injected into the cooking space 710. Thus, the steam and hot water can be used to cook food in the cooking space 710.

[0051] Continuing with reference to Figures 4 and 5, in some embodiments, the pipeline component 830 further includes an inlet pipe 836 and an injection pipe 837 between the fork pipe 835 and the injection head 840.

[0052] Steam and hot water can be injected into the cooking space 710 through the trifurcated pipe 835, the inlet pipe 836, the injection pipe 837, and the injection head 840 in sequence.

[0053] 4 and 5. In some embodiments, the drive component 820 includes a drive part 821, a fixed rod 822, a moving block 823, and an assembly rack 824.

[0054] The driving part 821 is electrically connected to the control part 810. The moving block 823 is movably mounted on the assembly frame 824 and pivoted to the fixed rod 822. The moving block 823 clamps the injection tube 837.

[0055] When the driving part 821 drives the moving block 823 to move relative to the assembly frame 824 and the fixed rod 822, the injection tube 837 is moved by the moving block 823, thereby adjusting the position of the injection head 840.

[0056] Thus, the spray head 840 can be located outside of the cooking area 600 or at different locations within the cooking area 600. In some embodiments, the location of the spray head 840 is the height of the spray head 840. In some embodiments, the height of the spray head 840 is the vertical height of the spray head 840.

[0057] For example, in this embodiment, the fixed rod 822 is a screw, which is rotationally driven by the driving part 821, and the fixed rod 822 is provided with a moving block 823 that matches the threads (not shown) of the fixed rod 822.

[0058] Therefore, when the driving part 821 rotates and drives the fixed rod 822, the moving block 823 moves relative to the assembly frame 824 and the fixed rod 822, and finally the position of the ejection head 840 is adjusted.

[0059] For example, in some embodiments, assembly frame 824 has a track (not shown) or a magnetic component (not shown), and moving block 823 has a configuration (not shown) that matches the track of assembly frame 824 or the magnetic component.

[0060] Therefore, when the driving part 821 drives the track or magnetic component of the assembly frame 824 , the moving block 823 moves relative to the assembly frame 824 and the fixed rod 822 , and finally adjusts the position of the ejection head 840 .

[0061] Please refer to Figure 8. Figure 8 is a schematic diagram of a cooking area 600 in accordance with an embodiment of the present invention, in which the cooking area 600 has a cooking vessel 700 disposed therein and the injection head 840 is not disposed therein.

[0062] When the injection head 840 is not positioned in the cooking area 600, the injection head 840 does not inject hot water or steam into the cooking area 600. At this time, the food cooking apparatus 100 can perform the above-mentioned preparation process or cleaning process (described in detail below).

[0063] 9 and 10 are jointly referenced. Figure 9 is a schematic diagram of a cooking area 600 in accordance with an embodiment of the present invention, with a cooking vessel 700 positioned within the cooking area 600 and a spray head 840 positioned in a first position within the cooking area 600.

[0064] 10 is a schematic diagram of a cooking area 600 in accordance with an embodiment of the present invention, where a cooking vessel 700 is positioned within the cooking area 600 and a jet head 840 is positioned at a second position within the cooking area 600.

[0065] 9 and 10, the position of the jet head 840 may be further away from the container bottom 720 (FIG. 9) or closer to the container bottom 720 (FIG. 10). However, the position of the jet head 840 is not limited to these two positions.

[0066] In some embodiments, through operation of the drive component 820, the injection head 840 can be positioned at different locations within the cooking space 710. Thus, the food preparation apparatus 100 can combine the injection of hot water and steam at different locations to achieve optimal cooking effects.

[0067] Reference is now made to Figure 11, which is a flowchart of a food preparation method according to an embodiment of the present invention. In some embodiments, the food preparation method is suitable for preparing ingredients placed in the cooking space 710, and includes steps S101 and S102.

[0068] In step S101, the controller 810 executes a preparation process for obtaining steam and hot water, and in step S102, the controller 810 executes a multi-stage cooking process.

[0069] In some embodiments, step S101 further includes determining, based on the cooking flow, whether the hot water and steam meet the conditions required for the cooking flow, and determining whether to add steam or hot water or to continue with step S102.

[0070] In some embodiments, if the multi-stage cooking process requires injecting hot water first, it is not necessary to prepare all the steam required in step S101 at once.

[0071] Similarly, in some embodiments, if the multi-stage adjustment process requires injecting steam first, it is not necessary to prepare all the required hot water at once in step S101.

[0072] Reference is also made to Figure 12, which is a partial flow chart of a food preparation method according to an embodiment of the present invention. In some embodiments, the multi-stage cooking process includes multiple cooking stages (also referred to as cooking process sections).

[0073] Each adjustment stage includes injecting steam into the cooking space 710 for a predetermined steam time and injecting a predetermined amount of hot water into the cooking space 710 (for example, steps S201 to S204).

[0074] In step S201, the controller 810 activates and opens the air valve 832 to inject steam into the cooking space 710 for a first predetermined steam time. In step S202, the controller 810 activates and opens the water valve 834 to inject a first predetermined amount of hot water into the cooking space 710.

[0075] In step S203, the controller 810 actuates the air valve 832 open to inject steam into the cooking space 710 for a second predetermined steam time.

[0076] In step S204, the controller 810 activates and opens the water valve 834 to inject a second predetermined amount of hot water into the cooking space 710. The first predetermined steam time and the second predetermined steam time can be set according to the cooking needs of different ingredients and may be the same or different.

[0077] Similarly, the first and second predetermined amounts of water can be set according to the cooking needs of different ingredients and can be the same or different. In some embodiments, the multi-stage cooking process includes injection of more steam and hot water.

[0078] Alternating between steam and hot water, heating and converting ingredients as needed, allows each ingredient to be cooked most efficiently. For example, requirements may include the type and volume of ingredients.

[0079] In this embodiment, the multi-stage cooking process only includes the above steps S201 and S202.

[0080] In some embodiments, step S202 further includes the controller 810 executing a steam preparation process to obtain steam. In other words, while injecting hot water, the first heater 420 can heat the liquid water to compensate for the steam pressure consumed in step S201 so that the steam pressure is sufficient to be used in step S203.

[0081] In this embodiment, the amount of hot water obtained in the preparation procedure is less than the sum of the first predetermined water amount and the second predetermined water amount (predetermined total water amount), and step S203 further includes a process in which the controller 810 executes a hot water preparation process to obtain hot water.

[0082] In other words, when steam is injected, the second heater 520 can heat liquid water to make up for the hot water consumed in step S202, resulting in a sufficient amount of hot water for use in step S204.

[0083] In various embodiments, each of steps S201 to S204 can be performed with the height of ejection head 840 fixed or not fixed, as needed.

[0084] That is, in each step from step S201 to step S204, the ejection head 840 may be positioned at a fixed height, or the ejection head 840 may be moved continuously, intermittently, or back and forth in a single stroke or multiple strokes. Furthermore, the movement speed of the ejection head 840 may also be adjusted as necessary.

[0085] In this embodiment, the control component 800 further includes a cleaning component 850. The steam generating device 400 includes a second steam outlet 440, and the steam generating device 400 is used to output steam to the cleaning component 850 through the second steam outlet 440.

[0086] Once the spray head 840 is positioned within the cleaning component 850, the controller 810 can control the steam generating device 400 to inject steam into the cleaning component 850 via the second steam outlet 440 to clean the spray head 840.

[0087] In some embodiments, the control component 800 further includes an exhaust component 860. The exhaust component 860 is connected to the cooking area 600 and the exhaust vent 220 to extract excess steam or hot air from the cooking area 600 and expel it from the food preparation appliance 100.

[0088] As described above, the multi-stage cooking process of the food preparation methods of the present invention allows the ingredients to be cooked to alternate between immersion in hot water, heating with steam, and stirring, resulting in more efficient cooking of the food.

[0089] In addition, since the entire amount of hot water and steam required for cooking is not injected at once, hot water can be generated (replenished) while steam is being injected, and steam can be generated (replenished) at the same time as hot water is injected, thereby shortening the time required to prepare hot water and steam.

[0090] Furthermore, food cooking devices according to several embodiments of the present invention use separate heating devices to generate hot water and steam, and can replenish hot water or steam as needed during cooking, eliminating the need to prepare the required hot water or steam before cooking begins.

[0091] Furthermore, the separate heating devices allow for a smaller volume of liquid water in the steam heating device, which results in the liquid water boiling faster, thereby significantly reducing the steam preparation time. In summary, the waiting time between cooking sessions can be reduced, thereby saving the total time spent on multiple cooking sessions. [Explanation of symbols]
