(First Embodiment)
In the first embodiment of the present invention, the case where the steam cooker is applied to the electric steamer 10 as a steam cooker will be described with reference to FIGS. 1 to 9.

(Overall composition of steamer)
The overall configuration of the steamer 10 will be described. FIG. 1 is a cross-sectional view of the steamer 10, and FIG. 2 is a component assembly view.

The steamer 10 includes a steamer body 11 and a steamer lid 12. The steamer meat 11 has a function of putting ingredients to be cooked. Further, the steamer lid 12 has a function of covering the steamer body 11 so as to close the opening of the steamer body 11. The steamer body 11 and the steamer lid 12 are formed by, for example, weaving a tree such as cedar or bamboo into a predetermined frame.

Further, the steamer 10 includes a steam generator 13. The steam generator 13 has a function of generating steam for steaming (cooking) foodstuffs. In the steamer 10, the steamer 11 is placed on the steam generator 13 with the steamer 11 containing the food covered with the steam lid 12, and the steam generated from the steam generator 13 steams the food.

The steam generator 13 includes a generator main body 20, a steam cylinder 50, and a container lid 80 (sink). The generator main body 20 has a function of assembling the steam cylinder 50 and the container lid 80. The steam cylinder 50 has a function of rectifying steam. The steam cylinder 50 is provided on the bottom 22 (bottom surface) of the container 21 of the generator main body 20. By aligning the mounting portion 51 (projection piece) provided at the lower end of the steam cylinder 50 so as to enter the insertion port of the cylinder mounting portion 23 provided at the bottom 22 of the container, and turning the steam cylinder 50 while pressing it, the container 21 ( The steam cylinder 50 can be attached to the generator body 20). Further, the steam cylinder 50 has a notch 52 (continuous passage) formed at the lower end. When the steam cylinder 50 is attached to the container 21, the inside of the steam cylinder 50 and the inside of the container 21 (outside of the steam cylinder 50) communicate with each other by the notch 52. Therefore, when water is put into the container 21, water also enters the inside of the steam cylinder 50.

The container lid 80 has a function of closing (covering) the container 21. The lid makes it easier to maintain the temperature inside the container 21. The user has the handle portion 81 of the container lid 80, aligns the recessed portion 82 provided in the container lid 80 with the lid positioning portion 24 provided in the container 21 (generator body 20), and covers the container 21 with the container lid 80. As a result, the opening of the container 21 can be closed with the container lid 80. By positioning and attaching the container lid 80 to the container 21, it is possible to prevent steam from escaping to the outside and allow steam from the steam cylinder 50 to reach the steamer body 11 through the penetrating portion 83 of the container lid 80. can. As will be described later, the container lid 80 is composed of a peripheral groove portion 86 lower than the central portion 84 and the edge portion 85, and also has a function as a saucer.

The generator main body 20 includes a housing 25 having a container 21 (tank), a heater 26, an energizing lamp 27, and a timer 28. The housing 25 has a function of assembling a heater 26, an energizing lamp 27, a timer 28, and the like. The heater 26 has a function of heating the water contained in the container 21. As the heater 26, for example, a planar heater provided in a circular shape on the bottom of the container 21 can be used. The steam cylinder 50 is attached to the container 21 so as to cover the exposed heater 26. Therefore, the water in the steam cylinder 50 heated by the heater 26 evaporates to become steam. The energizing lamp 27 has a function of emitting light when the steamer 10 is getting electric power. The timer 28 has a function of adjusting the time (cooking time) for heating the heater 26.

Further, the housing 25 has an upper body portion 30 and a lower body portion 31, and these are combined to form a housing 25. The upper body portion 30 has a function as a container 21 in which water to be steam is put. The container 21 has a scale 33 on the inner surface 32 (inner wall surface). The scale 33 has, for example, two water levels 33H and 33L. For example, by putting water in the container 21 so as to match one of the two water levels, an amount of water suitable for cooking can be put in the container 21. For example, water is put into the container 21 so that the water level is adjusted within the range of the upper limit 33H and the lower limit 33L of the scale 33. If the water level exceeds the upper limit 33H, there is a risk of spillage, while if the water level is below the lower limit 33L, there is a risk of emptying. According to the scale 33, steam can be appropriately generated.

Further, the container 21 is formed in a part of the opening edge 34 of the container and has a slope 35 inclined outward. By providing the slope 35, for example, when adjusting the amount of water or after cooking, it becomes easy to discard the water in the container 21 from the slope 35. Further, the container 21 is formed on the inner surface 32 and has a drainage guide 36 extending from the container bottom 22 (bottom surface) toward the slope 35. By tilting the container 21 (generator body 20) with the slope 35 facing downward when draining water from the slope 35, it is possible to easily drain water from the slope 35 along the drainage guide 36. Therefore, an amount of water suitable for cooking can be put into the cooking 21, and steam can be appropriately generated. By using the drainage guide 36 as one of the scales 33, the number of parts can be reduced.

A heater 26 is exposed on the bottom 22 of the container 21. A sealing portion 37 (for example, silicone packing) is provided around the exposed heater 26 in order to prevent water leakage. Further, under the heater 26, a holding portion 38 fixed to the lower body portion 31 is provided to support the heater 26. Further, under the lower body portion 31, a plurality of leg portions 39 are evenly arranged in order to stabilize the steamer 10 placed on the table.

(Steam cylinder)
The steam cylinder 50 will be described. 3, FIG. 4, FIG. 5, and FIG. 6 are a front view, a bottom view, a perspective view from the bottom surface side, and a cross-sectional view of the VI-VI line of FIG. 4, respectively. The steam cylinder 50 in the embodiment of the present invention is configured so that the lower end 54 (one end) and the opposite upper end 55 (the other end) are opened to open the hollow inside, and the opening of the upper end 55 is larger than the opening of the lower end 54. small. For example, the steam cylinder 50 may be configured to have a trumpet-shaped, bell-shaped, or truncated cone-shaped outer shape.

The steam cylinder 50 has a function of rectifying steam internally. In the steamer 10, the water heated on the lower end 54 side of the steam cylinder 50 boils, and the generated steam (steam) moves to the upper end 55 side of the steam cylinder 50 and is discharged from the opening of the upper end 55. The steam cylinder 50 has one or more raised portions 56 (ridge-shaped portions) formed on the inner surface 53. The raised portion 56 is formed so as to rise from the inner surface 53 of the steam cylinder 50 and extend from the lower end 54 side to the upper end 55 side of the steam cylinder 50. In the steam cylinder 50, the raised portion 56 is formed so as to be pushed out from the outside of the steam cylinder 50 to the inside.

For example, the cylindrical steam rectifying portion as in Patent Document 1 does not have a raised portion (ridge-shaped portion). In such a cylindrical steam rectifying section, the generation of steam had to be adjusted only by the size of the inner radius. However, in the steam cylinder 50, the internal size of the steam cylinder 50 can be adjusted by providing the raised portion 56. With such a steam cylinder 50, steam can be appropriately generated.

Further, the steam cylinder 50 is formed so that the opening of the upper end 55 is smaller than the opening of the lower end 54. Specifically, the steam cylinder 50 is configured to have an inner surface 53 such that the inside is tapered. That is, the inside of the steam cylinder 50 is narrowed (narrowed) from the lower end 54 toward the upper end 55. In the steam cylinder 50, the opening of the lower end 54 and the opening of the upper end 55 are formed in a circular shape, for example, in a plan view (bottom view). Therefore, in the steam cylinder 50, the inner radius decreases from the lower end 54 toward the upper end 55. According to such a configuration, the steam generated at the lower end 54 side is collected toward the upper end 55 side, so that steam can be appropriately generated from the steam cylinder 50.

Further, in order to efficiently boil water in the steam cylinder 50, it is preferable that the opening of the lower end 54 has a size that covers the heater 26. If the lower end opening remains the same size and the inner surface continues to the upper end opening (becomes a columnar shape), the internal volume remains large and the amount of water boiled in the steam cylinder increases. Therefore, in the steam cylinder 50, the inside is tapered to suppress the influence of the volume, and the efficiency of boiling water is increased, so that steam can be appropriately generated.

Further, the inner surface 53 of the steam cylinder 50 has an upper curved surface 57 such that the upper end 55 side of the steam cylinder 50 is narrowed in a dome shape. The internal space of the steam cylinder 50 surrounded by the upper curved surface 57 has a function as a buffer (air pool) when the steam generated on the lower end 54 side is discharged from the opening of the upper end 55. That is, even if the hot water is ejected when the steam is discharged from the hot water surface in the steam cylinder 50, it collides with the upper curved surface 57, so that it is possible to prevent the hot water from being ejected from the opening of the upper end 55. Therefore, steam can be appropriately generated from the steam cylinder 50.

Further, the inner surface 53 of the steam cylinder 50 has a lower curved surface 60 that expands toward the lower end 54 side of the steam cylinder 50. Further, the raised portion 56 has a raised end curved surface 61 that gradually decreases toward the lower end 54 side of the steam cylinder 50 on the lower curved surface 60. In the steam cylinder 50, the capacity (time) for generating steam, the method of rectifying steam, and the like are adjusted by the internal size of the portion where the raised portion 56 is present and the portion where the raised portion 56 is not present on the inner surface 53. The steam cylinder 50 is configured such that the radius of the lower curved surface 60 is larger than the radius of the raised end curved surface 61. Therefore, depending on the steam generated on the lower end 54 side, it is easier to rise from the lower curved surface 60 than the raised end curved surface 61. By adjusting the method of rectifying steam in this way, steam can be appropriately generated from the steam cylinder 50.

Further, the steam cylinder 50 is provided with a plurality of raised portions 56 at equal intervals in the circumferential direction with respect to the center O in a plan view (bottom view). Therefore, the steam generated on the lower end 54 side can be rectified to the upper end 55 side in a well-balanced manner, and steam can be appropriately generated from the steam cylinder 50. For example, as shown in FIG. 4, in the steam cylinder 50, six raised portions 56 are provided at equal intervals (equally divided) in the circumferential direction with respect to the center O. Further, in the steam cylinder 50, since the raised portion 56 rises from the inner surface 53, the space between the adjacent raised portions 56 is configured as a path 62 through which steam can easily pass. By adjusting the method of rectifying steam in this way, steam can be appropriately generated from the steam cylinder 50.

Further, in the steam cylinder 50, the opening of the upper end 55 is divided into a plurality of holes 65 by a runner portion 64 extending radially from the central hole 63. Therefore, the hole portion 65 extends from the central side toward the opening edge side (outside) in a plan view. It can be said that the upper end 55 in such a plan view is configured like a cross section of a citrus fruit such as grapefruit, for example. According to such a configuration, steam can be appropriately generated from the entire opening of the upper end 55 (central hole 63 and a plurality of holes 65).

(Container lid)
The container lid 80 will be described. 7 and 8 are a plan view of the central main part of the container lid 80 and a cross-sectional view taken along the line VIII-Oa-VIII of FIG. 7, respectively.

The container lid 80 has a central portion 84, a peripheral groove portion 86, and a penetrating portion 83 formed at a boundary between the central portion 84 and the peripheral groove portion 86. The penetrating portion 83 is formed in a ring shape in a plan view. When the container 21 (generator body 20) is covered with the container lid 80, the central portion 84 faces the upper end 55 of the steam cylinder 50. Further, the peripheral groove portion 86 is lower than the central portion 84 so as to enter the inside of the container 21 around the central portion 84. As a result, the steam released from the steam cylinder 50 collides with the back surface of the central portion 84 and is accumulated in the space around the central portion 84, and then passes through the penetrating portion 83 and passes through the surface of the container lid 80 (the surface of the central portion 84). Ascend to the side. According to such a configuration, steam can be appropriately generated from the penetrating portion 83.

Further, the container lid 80 has a slider portion 90 straddling the penetrating portion 83 from the central portion 84 to the peripheral groove portion 86. The slider portion 90 has a slider surface 92 that descends from the front of the upper surface edge 91 of the central portion 84. Specifically, the slider portion 90 has a slider surface 92 (stepped in FIG. 8) that is a recess from the upper surface edge 91 to the center side. As a result, the liquid that has fallen from the steamer 11 does not stay in the central portion 84 for a long time, but rather flows into the slider portion 90 more quickly.

Further, the container lid 80 has a wall portion 94 extending from the upper surface edge 91 of the central portion 84 to the slider edge 93 of the slider surface 92 on the penetrating portion 83. In the container lid 80, it is assumed that the steam acting on the cooking becomes a liquid (including the one discharged from the foodstuff. For example, in the case of meat, the liquid containing the discharged meat oil) and falls on the surface of the central portion 84. Also, it travels through the slider portion 90 and accumulates in the peripheral groove portion 86. Therefore, it is possible to prevent the used liquid from reaching the container 20 through the penetrating portion 83. Therefore, according to the container lid 80, it is possible to prevent the used liquid from being contained in the boiling water in the container 20 and appropriately generate steam.

Further, in the container lid 80, since the central portion 84 is formed in a dome shape with the central portion Oa as the apex, the used liquid that has fallen on the surface of the central portion 84 reaches the wall portion 94 of the upper surface edge 91. Can be done. Then, the used liquid is collected in the peripheral groove portion 86 along the slider portion 90. Further, the container lid 80 is configured such that the height h1 of the wall portion 94 on the slider surface 92 is higher than the height h2 of the wall portion 94 on the upper surface of the central portion 84. Therefore, even if the liquid flows through the slider surface 92, it can be prevented from falling to the penetrating portion 83. Therefore, according to the container lid 80, it is possible to prevent the used liquid from being contained in the boiling water in the container 20 and appropriately generate steam.

(How to use a steamer, how to manufacture food using a steamer)
The method of using the steamer 10 (method of producing food) according to the embodiment of the present invention will be described. FIG. 9 is a flowchart of how to use the steamer 10.

First, the steam cylinder 50 is set in the generator main body 20 (process S10). Specifically, the steam cylinder 50 is attached to the cylinder mounting portion 23 of the generator main body 20 (container 21) with the mounting portion 51 facing down.

Next, water is put into the container 21 (step S20). Specifically, water is added to the container 21 according to the scale 33 so that the amount is suitable for cooking. If the amount of water is small, it may cause emptying, and if the amount of water is large, it may cause boiling water to overflow. Therefore, put an appropriate amount of water in the container 21.

Next, the container lid 80 is set in the generator main body 20 (container 21) (step S30). Specifically, the container 21 is covered with the container lid 80 in accordance with the lid positioning portion 24 of the main body 20 with the recessed portion 82 in front (front side of the generator main body 20). If the opening of the container 21 is not closed by the container lid 80, it causes steam to escape. Further, if the container lid 80 is not fitted in the container 21, the steamer body 11 may fall down.

In addition, the ingredients are put in the steamer meat 11 (step S40). Specifically, the foodstuff is placed in the steamer 11 by creating an appropriate gap between the foodstuff and the foodstuff. This makes it easier for steam to pass between the ingredients, and the ingredients can be steamed well. By laying a cooking sheet or the like on the steamer meat 11, it is possible to prevent the odor of the food material from being transferred, sticking to the food, and soaking in the gravy. After that, the steamer lid 12 is set on the steamer body 11 (step S50).

Next, the steamer body 11 is set in the generator main body 20 (step S60). Specifically, the steamer body 11 covered with the steamer lid 12 is placed on the container lid 80. In the present embodiment, the case where the steamer 11 is set for one stage is described, but it may be set as multiple stages. Next, the power is turned on to the generator main body 20 (steamer 10) (step S70). Specifically, a power plug (not shown) is plugged into an outlet. As a result, the energizing lamp 27 lights up.

Next, a timer is set (step S80). Specifically, the timer 28 is turned to set the time according to the ingredients and the recipe. As a result, the water in the container 21 is heated by the heater 26, and steam is generated until the timer ends (step S82), and the foodstuff is steamed and cooked (step S84). When the timer expires, a buzzer sounds to notify the user, and heating by the heater 26 is stopped.

Next, the power of the steamer 10 (generator body 20) is turned off (step S90). Specifically, unplug the power plug from the outlet. After the time set by the timer 28 is completed, the steamer 11 can be removed from the generator main body 20, the steamer lid 12 can be removed, and the cooked food can be taken out from the steamer 11 and placed on a tableware plate. According to the steamer 10, steam can be appropriately generated, so that even a simple method can produce a satisfactory food.

The container 21A is made of a material (for example, made of stainless steel) that is heated by a high frequency electromagnetic force. The container 21A is set so that the steam cylinder 50 is located above the heating source 100 (for example, the top plate of the high frequency electromagnetic heater).

In the steamer 10A, the water heated on the lower end 54 side of the steam cylinder 50 boils, and the generated steam moves to the upper end 55 side of the steam cylinder 50 and is discharged from the opening of the upper end 55. The steam cylinder 50 has one or more raised portions 56 (ridge-shaped portions) formed on the inner surface 53. The raised portion 56 is formed so as to rise from the inner surface 53 of the steam cylinder 50 and extend from the lower end 54 side to the upper end 55 side of the steam cylinder 50. In the steam cylinder 50 set in the container 21A, the internal size of the steam cylinder 50 can be adjusted by providing the raised portion 56. Even with the steam cylinder 50 of such a steamer 10A, steam can be appropriately generated.

Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

In the above-described embodiment, the case where a planar heater provided so as to be exposed at the bottom of the container is used has been described. Not limited to this, a case may be used in which a protruding heater provided so as to protrude into the inside of the container is used.
