Description

  The present invention relates to a cooking device.

  Patent Document 1 describes a pressure-type rice cooker that is one of cookers. In this rice cooker, an exhaust passage for discharging the exhaust in the pan to the outside is formed in a lid that covers the top of the pan. An inner lid for closing the upper end opening of the pan is detachably disposed on the lid, and a gap between the inner lid and the lid constitutes a part of the exhaust passage. Further, a pressure valve for increasing the pressure in the pan to a pressure higher than the atmospheric pressure is disposed at the inlet (communication hole) of the exhaust passage.

  This rice cooker may be in a negative pressure state in which the inside of the pan is lower than the atmospheric pressure during the process of adjusting the pressure to a predetermined pressure higher than the atmospheric pressure. Therefore, in Patent Document 1, a negative pressure valve that opens when the inside of the pan is in a negative pressure state is disposed in the inner lid, the inside of the pan is returned to the atmospheric pressure state, and a liquid material (a rice cake) accumulated on the inner lid. Is refluxed into the pan.

  However, since the rice cooker of patent document 1 cannot recirculate unless the inside of a pan becomes negative pressure, there exists a possibility that the liquid substance may remain on the inner lid after the rice cooking process. If the lid is opened in this state, the accumulated liquid material may leak out from the outlet (exhaust port) of the exhaust passage. This problem appears remarkably in the case of a cooker that cooks various foods because the amount of liquid material discharged from the pan increases.

Further, on the side of the connection end 125 a of the outer wall 127, a support portion 134 that protrudes downward (inner lid main body 72 side) from the lower end of the opening end 125 b is provided.

  When the inner lid set 70 configured as described above is attached to the lid body 25 and the lid body 25 is opened, the connection port 121 is located at the lower end, the opening 129 is located at the upper end, and the upstream side exhaust passage is between them. A communication hole 84 </ b> B that is an inlet of 71 is located. The communication hole 84 </ b> B is located above half of the total height in the upstream side exhaust passage 71. Further, the discharge port 69 which is the outlet of the downstream side exhaust passage 64 is located between the connection port 121 and the communication hole 84B. As a result, even in a space surrounded by the lower container 66 and the upper cover 68 of the steam port unit 65, a predetermined amount of liquid material can be accommodated.

  The cooker 10 includes a control board disposed in the cooker main body 15, and a microcomputer (control means) mounted on the control board, based on the detection values of the temperature detection member and the pressure detection member, The on-off valves 86, 90, and 94 are controlled to perform cooking processing including cooking of ingredients and cooking of cooked rice.

  When cooking ingredients with this cooker 10, the ingredients or ingredients and seasoning soup (including water) are set in the cooking pan 11, and the inner lid set 70 is disposed on the lid 25 and operated. The panel unit 20 is operated.

  When the inner lid set 70 is not attached to the lid body 25, as shown in FIG. 5, the inner lid detection member 41 protrudes into the second arrangement portion 40, and this state is the inner lid detection sensor 45. Is detected by the output of. Further, when the inner lid set 70 is attached to the lid body 25 without attaching the upper cover member 101, it is similarly detected by the output of the inner lid detection member 41. When a cooking start operation is performed in this state, the microcomputer notifies the user by a piezoelectric buzzer on the control board or a liquid crystal display on the operation panel unit 20. Therefore, cooking can be prevented from being performed when the inner lid set 70 or the upper cover member 101 is not attached. Therefore, as shown in FIG. 1, the inner lid set 70 can be securely attached to the lid body 25 and the cooking pan 11 can be sealed and cooked.

  During cooking, the communication hole 84 </ b> A is closed by the safety valve 86 while heating the cooking pan 11 by energizing the induction heating coil. Moreover, the communication hole 84B is opened and closed by the pressure regulating valve 90, and the inside of the cooking pan 11 is regulated (pressurized or depressurized) between a set pressure higher than the atmospheric pressure. Further, the exhaust temperature in the upstream side exhaust passage 71 is detected by the lid temperature sensor 59 via the reinforcing cover 122.

  At this time, the liquid (heated or seasoned soup) heated in the cooking pan 11 passes through the communication hole 84 </ b> B of the pressure regulating valve 90 together with the exhaust, and the upstream exhaust between the inner lid body 72 and the upper cover member 101. It may flow into the passage 71.

  Among them, the steam (exhaust gas) passes through the duct member 125 formed by the closing plate 73 from the opening 129, flows into the downstream exhaust passage 64 through the connection ports 121 and 61, and passes through the discharge port 69 of the steam port unit 65. It is discharged to the outside through.

  The liquid material is stored in the upstream side exhaust passage 71 constituting the accommodation space. Then, the electric reflux valve 94 is opened at the set step, and the accumulated liquid material is refluxed into the cooking pan 11 through the communication hole 84C. At this time, the upstream side exhaust passage 71 that also serves as an accommodation space is formed by opening the upper cover member 101 so as to cover the upper part of the inner lid main body 72, so that the space for accommodating the liquid material is maximized. Can be secured to the limit. Therefore, it is not necessary to reduce the firepower to prevent spilling.

  Since the liquid material is refluxed into the cooking pan 11 by the electric reflux valve 94, the liquid material is basically set to be stored only in the lower portion of the duct member 125. However, the amount of discharge into the upstream exhaust passage 71 is large, and there is a possibility that it will be accumulated above the lower end of the duct member 125. However, since the duct member 125 of the present embodiment includes the inclined wall 126 that is inclined toward the inner lid main body 72, the duct member 125 can be prevented from flowing toward the downstream exhaust passage 64 (connection port 61).

  When cooking is finished and the user operates the operation member 32 to open the lid 25, the liquid material accumulated in the upstream exhaust passage 71 is the lower hinge in which the connection port 61 of the downstream exhaust passage 64 is formed. It collects on the connection part 19 side. At this time, as described above, in the upstream side exhaust passage 71, the liquid material is stored in the lower part of the duct member 125, so that the liquid material stored below the opening 129 is the downstream side exhaust passage. It can prevent flowing to 64 connection ports 61. Therefore, it is possible to suppress the liquid material from leaking from the discharge port 61 of the downstream side exhaust passage 64 to the outside.

  Even if the liquid material is located above the lower end of the duct member 125 with the lid body 25 closed, the duct member 125 is connected to the downstream exhaust passage 64 with the lid body 25 open. 61 extends upward from the communication hole 84B, which is the inlet of the upstream exhaust passage 71, so that the amount of liquid material entering the inside from the opening 129 and flowing to the discharge port 61 of the downstream exhaust passage 64 is minimized. be able to.

  Thus, in the cooking device 10 of the present invention, the liquid material discharged to the upstream side exhaust passage 71 that is the accommodation space is prevented from flowing toward the downstream side exhaust passage 64 and leaking from the discharge port 69 to the outside. It can be substantially prevented. Since the duct member 125 is disposed in the upper cover member 101 of the inner lid set 70 that forms the upstream side exhaust passage 71, the structure can be simplified, and both the duct and the member 125 can be used when cleaning the inner lid set 70. Can be cleaned together.

  In addition, in the present embodiment, since the upstream exhaust passage 71 is formed by the inner lid set 70, a surface (inner lid arrangement) of the lid body 25 on which the inner lid set 70 is arranged during cooking is disposed. The portion 36) does not adhere to the exhaust gas containing the ingredients of ingredients and the liquid material. In particular, in the present embodiment, the lid 25 is provided with the inner lid detection sensor 45 so that cooking is not performed in a state where the inner lid set 70 or the upper cover member 101 is not attached. Can prevent dirt. Therefore, the cleanability of the cooking device 10 can also be improved in this respect.

  In addition, the cooking device 10 of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, the duct member 125 is formed separately from the upper cover member 101, but may be integrally provided so as to be recessed in the top wall 102. Further, the duct member 125 is not limited to a cylindrical shape, and may be any configuration (shape) that can send liquid or gas. In addition, the upper cover member 101 is disposed on the inner lid body 72 to form the upstream exhaust passage 71 that also serves as a storage space. However, the inner lid body 72 (inner lid) is covered without using the upper cover member 101. The upstream side exhaust passage 71 may be formed between the inner lid body 72 and the lower plate 26 of the lid body 25 by being mounted on the body 25.

  In the present invention, a duct (duct member 125) is provided in a housing space (upstream exhaust passage 71) formed by mounting the inner lid (inner lid body 72), and a liquid material is placed in the downstream exhaust passage 64 of the lid 25. The structure which suppresses flowing is the feature. Therefore, the cooker 10 is not limited to the cooker 10 that can cook various ingredients, and can be applied to a rice cooker that can only cook rice. Moreover, it is applicable not only to the structure which provides the cooker main body 15 which has a heating means but the cooking pot 11 which arrange | positions the cover body 25 so that opening and closing is possible, and uses the existing stove of a household kitchen as a heating means. It is.
