Abstract
Description
[Technical Field]
[0001] The present invention relates to a cooking appliance. [Background technology]
[0002] In the past, a water-soluble bagged rice was proposed that "allows the desired amount of rice to be obtained immediately and accurately without measuring each time it is cooked, is particularly suitable for cooking rice while camping, and also allows the rice to be seasoned" (see, for example, Jitsugyo Publication No. 61-40144). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Publication No. 61-40144 Summary of the Invention [Problem to be solved by the invention]
[0004] When food ingredients wrapped in so-called edible film (hereinafter sometimes referred to as "edible film-wrapped food ingredients") as described above are added with water and cooked, the edible film dissolves in water. However, as the amount of water decreases during cooking, water-soluble polysaccharides, such as starch, cellulose, and gum, which are the raw materials for the edible film, adhere to the surface of the food ingredient. When food ingredients with water-soluble polysaccharides adhered to their surface are heated, the food ingredient may not be heated evenly. For this reason, when edible film-wrapped food ingredients are cooked under the same conditions as food ingredients not wrapped in edible film (hereinafter sometimes referred to as "non-edible film-wrapped food ingredients"), uneven heating of the edible film-wrapped food ingredients may occur, resulting in insufficient cooking. For this reason, there is a strong demand for a cooker that can cook edible film-wrapped food ingredients in addition to food ingredients not wrapped in edible film.
[0005] An object of the present invention is to provide a cooker that can cook not only food materials not wrapped in an edible film, but also food materials wrapped in an edible film. [Means for solving the problem]
[0006] The cooker according to the present invention has a normal cooking mode for cooking ingredients that are not wrapped in edible film, and an edible film cooking mode for cooking ingredients that are wrapped in edible film.
[0007] According to the above configuration, not only can food ingredients not wrapped in an edible film be cooked, but also food ingredients wrapped in an edible film can be cooked.
[0008] In the present invention, the water absorption step in the edible film cooking mode is preferably carried out at a higher temperature than the water absorption step in the normal cooking mode.
[0009] According to the above configuration, in the water absorption step, food material wrapped in an edible film can be made to absorb water in the same manner as food material not wrapped in an edible film.
[0010] In the present invention, it is preferable that the water absorption step in the edible film cooking mode is carried out for a longer time than the water absorption step in the normal cooking mode.
[0011] According to the above configuration, in the water absorption step, food material wrapped in an edible film can be made to absorb water in the same manner as food material not wrapped in an edible film.
[0012] In the present invention, it is preferable that the temperature increase rate in the temperature increase step in the edible film cooking mode is slower than the temperature increase rate in the temperature increase step in the normal cooking mode.
[0013] According to the above configuration, the food material wrapped in the edible film can be made to absorb water in the temperature raising step in the same manner as food material not wrapped in the edible film.
[0014] In the present invention, it is preferable that at least two of the following conditions be satisfied: (1) the water absorption process in the edible film cooking mode is carried out at a higher temperature than the water absorption process in the normal cooking mode; (2) the water absorption process in the edible film cooking mode is carried out for a longer time than the water absorption process in the normal cooking mode; and (3) the temperature rise rate in the temperature rise process in the edible film cooking mode is slower than the temperature rise rate in the temperature rise process in the normal cooking mode.
[0015] According to the above configuration, food materials wrapped in an edible film can be made to absorb water in the water absorption step and the temperature raising step in the same manner as food materials not wrapped in an edible film.
[0016] In the present invention, it is preferable that in the edible film cooking mode, a high-power heating step is executed in which heating is performed with a higher power than in the heating step of the normal cooking mode.
[0017] According to the above configuration, when cooking food wrapped in edible film in the edible film cooking mode, uneven heating of the food wrapped in edible film can be reduced compared to when cooking in the normal cooking mode.
[0018] In the present invention, it is preferable that the high-power heating step be performed multiple times in the edible film cooking mode.
[0019] According to the above configuration, when cooking food wrapped in edible film in the edible film cooking mode, uneven heating of the food wrapped in edible film can be further reduced compared to when cooking in the normal cooking mode. [Brief explanation of the drawings]

[0048] <Rice cooking process of the rice cooker according to the embodiment of the present invention> The rice cooker 100 according to an embodiment of the present invention has a "normal rice cooking mode" and an "edible film rice cooking mode." In both modes, the rice cooking process of the rice cooker 100 according to an embodiment of the present invention involves a "water absorption process," a "heating process," a "cooking process (heating process)," and a "steaming process." Below, each of the above processes will be described in detail, comparing (A) "normal rice cooking mode" with (B) "edible film rice cooking mode."
[0049] (1) Water absorption process (1-A) Water absorption process in "normal cooking mode" During the water absorption process in the "normal rice cooking mode," the temperature of the inner pot 130 containing the edible film-unwrapped rice (hereinafter sometimes simply referred to as "rice") and water is regulated by the induction heating coil 113 so that it reaches a set temperature (e.g., 28°C).
[0050] (1-B) Water absorption process in "edible film rice cooking mode" During the water absorption process in the "edible film rice cooking mode," the temperature is regulated by induction heating coil 113 so that the temperature of inner pot 130 containing edible film-packaged rice and water is set to a temperature higher than the set temperature in the "normal rice cooking mode" (for example, a temperature in the range of 34°C to 40°C) (i.e., during the water absorption process in the "edible film rice cooking mode," water absorption is carried out at a higher temperature than during the water absorption process in the "normal rice cooking mode") (see Figure 2). Note that, because edible film dissolves in water when placed in water, during the water absorption process in the "edible film rice cooking mode," both normal rice grains and water in which the edible film has dissolved are present.
[0051] (2) Heating process (A) In the heating process in the "normal rice cooking mode," the temperature of rice in water is raised. Also, (B) in the heating process in the "edible film cooking mode," the temperature of rice in water with dissolved edible film is raised. In these heating processes, the microcomputer board CB sets the heating output of the induction heating coil 113 to a predetermined heating output. In both modes, the temperature of the rice in the inner pot 130 is raised by the induction heating coil 113 for a predetermined period of time.
[0052] (3) Cooking process (heating process) In the cooking process in the rice cooker 100 according to the embodiment of the present invention, first, a "first half cooking process" is carried out, and then a "second half cooking process" is carried out. These processes will be described in detail below.
[0053] (3-1) First half of cooking process In the first half of cooking, the microcomputer board CB sets the heating power output of the induction heating coil 113 to a predetermined value. In either mode, the rice and water in the inner pot 130 are heated by the induction heating coil 113 for a predetermined period of time.
[0054] (3-2) Late cooking process In the latter half of cooking, the microcomputer board CB sets the heating output of the induction heating coil 113 to a predetermined heating output. Note that this heating output of the induction heating coil 113 may be set to the same heating output as the heating output of the induction heating coil 113 in the former half of cooking, or may be set to a different heating output. In the latter half of cooking in either mode, the rice and water in the inner pot 130 are heated by the induction heating coil 113 for a predetermined time.
[0055] (4) Steaming process In the steaming process in either mode, the microcomputer board CB sets the heating power output of the induction heating coil 113 to a predetermined heating power output. Then, in either mode, the rice in the inner pot 130 is steamed for a predetermined time.
[0056] <Features of the rice cooker according to the embodiment of the present invention> The rice cooker 100 according to an embodiment of the present invention is equipped with a "normal cooking mode" for cooking ingredients not packaged in edible film, and an "edible film cooking mode" for cooking ingredients packaged in edible film. Therefore, it is possible to cook not only ingredients not packaged in edible film, but also ingredients packaged in edible film. Furthermore, the water absorption process in the "edible film cooking mode" of this rice cooker 100 is carried out at a higher temperature than the water absorption process in the "normal cooking mode." Therefore, when edible film-packaged ingredients are cooked in the "edible film cooking mode," the ingredients packaged in edible film can absorb more water during the water absorption process than when edible film-packaged ingredients are cooked in the "normal cooking mode." In other words, during the water absorption process in the "edible film cooking mode," the ingredients packaged in edible film can absorb water to the same extent as when cooking ingredients not packaged in edible film during the water absorption process in the "normal cooking mode."
[0057] <Modification> (A) In the previous embodiment, the present invention is applied to the pressure-type rice cooker 100, but the present invention may also be applied to a non-pressure-type rice cooker (a rice cooker without a pressurizing device).
[0058] (B) In the previous embodiment, the present invention is applied to an IH rice cooker 100, but the present invention may also be applied to a non-IH rice cooker (a rice cooker equipped with a sheath heater or the like as heating means for the inner pot).
[0059] (C) In the rice cooker 100 according to the previous embodiment, the water absorption process in the "edible film cooking mode" was carried out at a higher temperature than the water absorption process in the "normal cooking mode." Alternatively, the water absorption process in the "edible film cooking mode" may be carried out for a longer time than the water absorption process in the "normal cooking mode." That is, in the water absorption process in the "normal cooking mode," rice not packaged in an edible film is allowed to absorb water for a set time (e.g., 16 minutes), whereas in the water absorption process in the "edible film cooking mode," rice packaged in edible film is allowed to absorb water for a set time longer than in the "normal cooking mode" (e.g., 21 minutes to 27 minutes) (see FIG. 3). In this case, the water absorption temperature in the water absorption process, the temperature-raising process, the cooking process (heating process), and the steaming process are carried out under the same conditions in the "normal cooking mode" and the "edible film cooking mode."
[0060] In rice cooker 100 according to this modification, the water absorption process in the "edible film cooking mode" takes longer than the water absorption process in the "normal cooking mode." Therefore, when edible film-packaged ingredients are cooked in the "edible film cooking mode," the ingredients wrapped in edible film can absorb more water in the water absorption process than when edible film-packaged ingredients are cooked in the "normal cooking mode." In other words, in the water absorption process in the "edible film cooking mode," the ingredients wrapped in edible film can absorb water to the same extent as when cooking ingredients not wrapped in edible film in the water absorption process in the "normal cooking mode."
[0061] (D) In the rice cooker 100 according to the previous embodiment, the water absorption process in the "edible film cooking mode" was carried out at a higher temperature than the water absorption process in the "normal rice cooking mode." Alternatively, the temperature may be increased at a slower rate in the temperature increase process in the "edible film cooking mode" than in the temperature increase process in the "normal rice cooking mode." That is, during the heating process in the "normal rice cooking mode," the microcomputer board CB sets the heating output of the induction heating coil 113 to a set heating output (for example, if 16 seconds is one cycle, the heating output of the induction heating coil 113 is set to 80% for 16 seconds), and the temperature of the rice not wrapped in edible film in the inner pot 130 is raised by the induction heating coil 113 for the set time, whereas during the heating process in the "edible film cooking mode," the microcomputer board CB sets the heating output of the induction heating coil 113 to a set heating output that is lower than the set heating output in the "normal rice cooking mode" (for example, if 16 seconds is one cycle, the heating output of the induction heating coil 113 is set to 70% for 16 seconds), and the temperature of the rice wrapped in edible film in the inner pot 130 is raised by the induction heating coil 113 for the set time (see Figure 4).
[0062] In rice cooker 100 according to this modification, the rate of temperature rise during the temperature rise process in the "edible film cooking mode" is slower than the rate of temperature rise during the temperature rise process in the "normal cooking mode." Therefore, when edible film-packaged ingredients are cooked in the "edible film cooking mode," water absorption by ingredients wrapped in edible film can be promoted during the temperature rise process compared to when edible film-packaged ingredients are cooked in the "normal cooking mode." In other words, the temperature rise process in the "edible film cooking mode" can promote water absorption by ingredients wrapped in edible film to the same extent as when cooking ingredients not wrapped in edible film during the temperature rise process in the "normal cooking mode."
[0063] (E) Although not specifically mentioned in the previous embodiment, in the first half of cooking in the "edible film cooking mode," heating may be performed at a higher heat output than in the first half of cooking in the "normal cooking mode." That is, in the first half of cooking in the "normal cooking mode," the microcomputer board CB sets the heating output of the induction heating coil 113 to a set heating output (for example, if one cycle is 16 seconds, the heating output of the induction heating coil 113 is set to 80% for 14 seconds in one cycle and to 0% for 2 seconds), and the temperature of the non-edible film-packaged rice in the inner pot 130 is raised for a set period of time by the induction heating coil 113, whereas in the first half of cooking in the "edible film cooking mode," the microcomputer board CB sets the heating output of the induction heating coil 113 to a set heating output higher than the set heating output in the "normal cooking mode" (for example, if one cycle is 16 seconds, the heating output of the induction heating coil 113 is set to 90% for 16 seconds). Then, the rice wrapped in edible film in the inner pot 130 is heated for a set time (see FIG. 5). In this modified example, high heat heating is performed once in the first half of the cooking process in the "edible film rice cooking mode," but high heat heating may be performed two or more times.
[0064] In the rice cooker 100 according to this modification, the first half of cooking in the "edible film cooking mode" is heated at a higher heat than in the first half of cooking in the "normal cooking mode." As a result, when cooking food ingredients packaged in edible film, convection can occur even in the cooking liquid in which water-soluble polysaccharides such as starch, cellulose, and gum, which are the raw materials for the edible film, are dissolved, and uneven heating of food ingredients packaged in edible film can be reduced compared to when cooking food ingredients packaged in edible film in the "normal cooking mode."
[0065] (F) Although not specifically mentioned in the previous embodiment, high-power heating may be performed in the latter half of cooking in the "edible film cooking mode." That is, in the latter half of cooking in the "edible film cooking mode," the microcomputer board CB sets the heating output of the induction heating coil 113 to a set heating output that is higher than the set heating output in the "normal cooking mode" (for example, if one cycle is 16 seconds, the heating output of the induction heating coil 113 is set to 90% for 16 seconds). Then, the rice wrapped in edible film in the inner pot 130 is heated for a set time (see FIG. 6). Note that in this modified example, high-power heating is performed once in the latter half of cooking in the "edible film cooking mode," but high-power heating may be performed two or more times. This modified example may also be performed in combination with modified example (E).
[0066] In the "edible film cooking mode" of rice cooker 100 according to this modification, high-power heating is performed in the latter half of cooking. This makes it possible to further prevent uneven heating of food wrapped in edible film when cooking food wrapped in edible film.
[0067] (G) In the rice cooker 100 according to the previous embodiment, the rice cooker was configured to satisfy only the condition (G1) that the water absorption process in the "edible film cooking mode" is carried out at a higher temperature than the water absorption process in the "normal cooking mode." However, in the present invention, in addition to the above condition (G1), the rice cooker may be configured to satisfy two or more of the following conditions: (G2) that the water absorption process in the "edible film cooking mode" is carried out for a longer time than the water absorption process in the "normal cooking mode" (see variant (C)); and (G3) that the temperature rise rate in the temperature rise process in the "edible film cooking mode" is slower than the temperature rise rate in the temperature rise process in the "normal cooking mode" (see variant (D)). Alternatively, the rice cooker may be configured to satisfy all of the above conditions (G1) to (G3).
[0068] The above modified examples may be applied individually or in combination. [Explanation of symbols]
