Description

  The present invention relates to a rice cooker having a rice cooking function other than white rice, such as cooked rice.

  In recent years rice cookers have added various ingredients such as meat such as chicken, seafood such as clams, vegetables such as burdock and carrots, etc. in addition to white rice in order to respond to a wide range of user orientation with the development of microcomputers. It is possible to cook cooked rice such as rice and clams.

  As this kind of rice cooker, Patent Document 1 suspends the steaming process temporarily in the steaming process to highlight the difference in seasoning and texture between the white rice and the various ingredients to be added. There is described a rice cooker that can be opened once and the steaming process can be performed again after the ingredients are charged.

JP 2009-000186 A

  In the above-mentioned conventional technology, when the user opens the lid of the rice cooker in the middle of cooking rice and throws ingredients into the rice cooker described in Patent Document 1, steam comes out of the rice cooker and the user creates steam. There is a possibility of bathing. Therefore, there may be a problem in safety. In addition, there is a problem that it is not easy to use because it is necessary to add ingredients during cooking.

  The present invention has been made to solve the above problems, and includes a main body, an outer lid that covers the upper surface opening of the main body, an inner hook that is detachably accommodated in the main body, and a lower portion of the inner hook. Heating means provided to heat the inner pot, temperature detection means provided below the inner pot to detect the temperature of the inner pot, operation unit provided to the main body for setting various rice cooking menus, A material supply box for storing the material provided at the upper part of the outer lid, and a device provided between the material supply box and the inner hook for opening and closing the material using the driving means to put the material into the inner hook. A supply valve and a control unit that controls the heating unit and the driving unit based on the setting of the operation unit are provided.

  According to the present invention, a safe and convenient rice cooker can be provided.

It is side surface sectional drawing which shows the rice cooker which concerns on this embodiment. It is an operation part of the rice cooker. It is one Example of the flowchart figure of the rice cooking process of the rice cooker.

  Hereinafter, the rice cooker which concerns on one Embodiment of this invention is demonstrated using drawing.

  FIG. 1 is a side sectional view showing a rice cooker according to the present embodiment.

  As shown in FIG. 1, 1 is a main body of a rice cooker. An inner hook 3 is detachably inserted into the main body 1. On the upper surface of the main body 1, an outer lid 2 including an inner lid 4 that covers the upper surface openings of the main body 1 and the inner hook 3 is provided so as to be freely opened and closed.

  An operation unit 6 for operating various menus is provided on the upper surface of the outer lid 2.

  Reference numeral 5 denotes a heating means including an induction heating coil for induction heating the inner pot 3. Thereby, the inner pot 3 is uniformly induction-heated.

  A temperature detection means 10 is provided at the lower part of the main body 1 so as to contact the outer bottom of the inner hook 3, and temperature information detected by the temperature detection means 10 is input to the control unit 11.

  The control unit 11 controls the operation of the heating unit 5 during the rice cooking process based on the temperature information of the outer bottom portion of the inner pot 3 by the temperature detection unit 10.

  In the upper part of the outer lid 2, an ingredient supply box 7 for introducing ingredients into the inner pot 3 during the rice cooking process is provided. The material supply box 7 is provided with an upper surface opening 7d into which the material is placed above, and a supply box lid 7a covering the upper surface opening 7d is provided to be openable and closable around the supply box hinge shaft 7b. An optical sensor 9 that detects the remaining amount of the material is provided on the lower side inside the material supply box 7, thereby detecting the presence or absence of the remaining material in the material supply box 7 and inputting it to the control unit 11. The optical sensor 9 includes, for example, a light emitting unit 9a that emits light and a light receiving unit 9b that receives the light, and determines that there is an ingredient when the light is blocked. In addition, the bottom surface of the ingredient supply box 7 is provided with an inclination so that the ingredient can be easily put into the inner pot 3.

  Below the ingredient supply box 7, a supply valve 8 is provided for feeding the ingredient contained in the ingredient supply box 7 into the inner hook 3. The supply valve 8 is opened / closed via the control means 11, and a driving means such as a solenoid or a motor is used for opening / closing.

  FIG. 2 shows the operation unit 6 of the rice cooker, which will be described below.

  The operation unit 6 sets the cooking menu and ingredients input time at the user's discretion. The display unit 12 displays the selected cooking menu and ingredients input time on a liquid crystal display or the like, and starts cooking. There are a rice cooking key 13, a cut key 14 for canceling the rice cooking process, a menu key 15 for selecting a rice cooking menu, and a material input key 18 for setting the timing (time / process) of material input. In addition, it has a heat retention key 16 for keeping the cooked rice warm, a reservation key 17 for setting the cooking time of the rice, and the like.

  The rice cooker of a present Example becomes the above structure, and demonstrates the operation | movement of the material input in a rice cooking process below.

  First, the user puts the scoured rice and a specified amount of water commensurate with the amount of rice into the inner pot 3. Next, the ingredients suitable for the amount of rice are put into the ingredient supply box 7, the rice cooking menu is selected with the menu key 15, and the ingredients are introduced with the ingredient input key 18 ( Time / process). It is also possible to automatically set the optimum timing for the material that has been confirmed in advance by setting the material to be loaded by pressing the material loading key 18.

  FIG. 3 is one example of a flowchart of the rice cooking process of the rice cooker, and will be described below according to the flowchart of FIG.

  In step 100, the rice cooking key 13 is pressed to start the rice cooking process.

  Next, in step 101, the temperature of the rice and water in the inner pot 3 is heated by the heating means 5 based on the temperature information of the temperature detecting means 10 as determined by the control unit 11, and step 102 is a steaming process. .

  Next, in step 103, the timing (time) of material input set by the user is measured, and when the set timing elapses, the supply valve 8 is opened in step 104 and the material in the material input box 7 is inserted. Put into the pot 3. In step 105, the optical sensor 9 provided in the ingredient supply box 7 confirms whether any ingredients remain.

  In step 106, the supply valve 8 is closed, and the process proceeds to a heat retention process in step 107.

  It should be noted that the timing (time / process) of loading the ingredients that can be set with the ingredient throwing key 18 can be set at any timing in the rice cooking process, so that the user's preference can be met.

  From the above, it becomes possible for the user to automatically insert ingredients at any timing of the user without opening and closing the lid of the rice cooker.

  According to this embodiment described above, a rice cooker that is safe and easy to use can be provided.
