Reference numeral 11 denotes a pressure adjusting unit. The pressure adjusting unit 11 moves the weight 10. The pressure adjusting unit 11 is constituted by a solenoid having, for example, a coil and a plunger (movable iron core) inserted into the coil, and the plunger is moved depending on whether or not the coil is energized. When the weight 10 is moved from the steam port 11 a by the pressure adjusting unit 11, the steam port 11 a, the in-lid communication path 18, and the external steam port 9 communicate with each other, and the steam in the cooking container 5 is outside the main body 1.

The steam port 12a of each unit, the in-lid communication passage 18 and the external steam port 9 communicate with each other, and form a steam passage for discharging the steam in the cooking vessel 5 to the outside of the main body 1. The weight 12b blocks the steam port 12a in a movable manner. The discharge adjusting unit 12c is configured by a solenoid, for example. The discharge adjusting unit 12c is arranged with the weight 10 facing the steam port 12a.

Reference numeral 21 denotes a control unit. The control unit 21 controls the operation of the inverter unit 22 based on inputs from the temperature sensor 4 and the operation display unit 14. Moreover, the control part 21 controls the operation | movement of the pressure regulation part 11 and the discharge | emission adjustment part 12c of each unit.

(Operation)
Next, the operation of the heating cooker according to the first embodiment will be described.
The user puts an object to be heated such as a material for making an arbitrary menu into the cooking container 5. Thereafter, the user places the cooking container 5 on the container cover 2 and closes the outer lid 8. When the outer lid 8 is closed, the lid packing 7 of the inner lid 6 is pressed against the flange portion of the cooking vessel 5 and hermetically sealed. The user inputs an operation for starting cooking using the operation display unit 14. The control unit 21 starts the cooking by operating the inverter unit 22 in accordance with the operation input from the operation display unit 14 and a preset cooking menu.

  A high frequency current is supplied from the inverter unit 22 to the heating coil 3 to generate a high frequency magnetic field. The cooking vessel 5 is magnetically coupled to the heating coil 3 and the opposed surface of the heating coil 3 is excited to induce eddy current. Joule heat is generated by the eddy current and the resistance of the cooking vessel 5, and the cooking vessel 5 generates heat to heat the object to be heated. When the object to be heated is heated, steam is generated.

  During cooking, the pressure adjusting unit 11 puts the weight 10 in a state of closing the steam port 11a. For example, when the pressure adjusting unit 11 is configured by a solenoid, the plunger is drawn. In addition, the discharge adjusting unit 12c in each unit of the steam discharge unit 12 presses the weight 10 against the steam port 12a so as to prevent the weight 10 from moving. For example, when the discharge adjusting portion 12c is constituted by a solenoid, the plunger is pushed out.

  When the object to be heated in the cooking container 5 is heated, steam is generated from the object to be heated. When steam is generated from the object to be heated, discharge of the steam is hindered by pressure due to the weight of the weight 10 that blocks the steam port 11a, and pressure is applied to the cooking vessel 5. When the pressure in the cooking vessel 5 rises higher than the pressure that blocks the steam port 11a due to the weight of the weight 10, the weight 10 is pushed away from the steam port 11a by the pressure in the cooking vessel 5. When the weight 10 is pushed away from the steam port 11 a, the steam in the cooking container 5 is discharged, the pressure in the cooking container 5 decreases, and the steam port 11 a is closed again by the weight of the weight 10.

  In this way, during cooking, the cooking container 5 does not exceed a pressure (balance pressure) at which the pressure at which the weight 10 blocks the steam port 11a and the pressure at which the pressure in the cooking container 5 pushes off the weight 10 is balanced. The pressure inside is maintained. The balance pressure by the weight 10 and the steam port 11a is set to the upper limit value of the pressure in the cooking vessel 5, for example. This balance pressure is a pressure determined by the opening area of the steam port 11 a and the weight of the weight 10. For example, if the steam port 11a is φ1 mm and the weight 10 is 10 g, the balance pressure is approximately 2.2 atmospheres. That is, the upper limit of the pressure applied to the cooking container 5 during cooking is approximately 2.2 atmospheres.

  During cooking, the steam port 12a of each unit of the steam discharge unit 12 is blocked by the pressure of the discharge adjusting unit 12c that presses the weight 12b against the steam port 12a in addition to the weight of the weight 12b. That is, the steam port 12a of each unit is kept closed regardless of the pressure in the cooking vessel 5.

  When the cooking is finished, the control unit 21 stops the operation of the inverter unit 22. Even after the heating is completed, the steam port 11a is blocked by the dead weight of the weight 10, and the pressure in the cooking container 5 is maintained in a state higher than the atmospheric pressure. For example, if the outer lid 8 is opened in this state, a sudden pressure change may cause bumping of the heated object, and the hot heated object may jump out of the cooking container 5. For this reason, the outer lid 8 must be opened after the pressure in the cooking vessel 5 has dropped to atmospheric pressure.

  For example, when the pressure adjusting unit 11 is driven and the weight 10 is moved from the steam port 11a and the steam port 11a is opened, the pressure in the cooking vessel 5 is reduced to atmospheric pressure all at once. Thereby, the pressure in the cooking vessel 5 may change abruptly and bumping may occur in the heated object in the cooking vessel 5. Further, the higher the pressure in the cooking container 5, the more steam is discharged from the steam port 11a, the greater the momentum of discharge, and the higher the possibility that the user will touch the steam.

  Therefore, in the heating cooker according to Embodiment 1, when the cooking vessel 5 is heated in a state where the steam passage is closed and then the steam passage is opened, the steam discharge unit 12 gradually releases the steam in the cooking vessel 5. To discharge.

  Here, each unit of the steam discharge unit 12 is set so that the balance pressure at which the pressure at which the weight 12b blocks the steam port 12a and the pressure at which the pressure in the cooking vessel 5 pushes off the weight 12b is balanced. Yes. Moreover, the balance pressure of each unit of the steam discharge part 12 is set to a pressure lower than the balance pressure by the weight 10 and the steam port 11a.

  This balance pressure is a pressure determined by the opening area of the steam port 12a and the weight of the weight 12b. For example, the weights of the weights 12b of each unit are all set to 10g. The diameter of the steam port 12a of the unit A is set to φ1.11 mm. The diameter of the steam outlet 12a of the unit B is set to φ1.24 mm. The diameter of the steam port 12a of the unit C is set to φ1.57 mm. The diameter of the steam port 12a of the unit D is set to φ2.48 mm. In this example, the balance pressure of unit A is approximately 2.0 atmospheres. The balance pressure of unit B is approximately 1.8 atmospheres. The balance pressure of unit B is approximately 1.5 atmospheres. The balance pressure of unit B is approximately 1.2 atmospheres. Thus, the balance pressure of each unit is set to be different depending on the combination of the opening area of the steam port 12a and the weight of the weight 12b.

  When the steam in the cooking container 5 is discharged after cooking, the control unit 21 sequentially drives the discharge adjusting unit 12c in each unit of the steam discharge unit 12 to sequentially release the weight 12b from being pressed by the discharge adjusting unit 12c. Then, the weight 12b of each unit is moved sequentially. The order in which the discharge adjusting unit 12c in each unit of the steam discharge unit 12 is driven is driven in the order from the unit with the highest balance pressure to the unit with the lowest. Further, the discharge adjusting unit 12c of each unit is driven with a time interval, and the weights 12b of each unit are sequentially moved with a time interval.

FIG. 3 is a diagram for explaining the operation of the heating cooker according to the first embodiment.
An example of the operation | movement which discharges | emits the vapor | steam in the cooking container 5 is demonstrated using FIG. In addition, the vertical axis | shaft of FIG. 3 shows the pressure in the cooking container 5, and a horizontal axis shows time. Moreover, in the example of FIG. 3, the balance pressure by the weight 10 and the steam port 11a is set to 2.2 atmospheres, and the balance pressure of the units A to D of the steam discharge unit 12 is 2.0 atmospheres and 1.8 atmospheres. , 1.5 atm, and 1.2 atm are set. In FIG. 3, the solid line indicates the case where the steam is discharged by the operation of the steam discharge unit 12, and the alternate long and short dash line indicates the case where the steam is discharged only by the operation of the pressure adjusting unit 11.

  The control unit 21 drives the discharge adjustment unit 12c of the unit A at time t0. When the discharge adjustment unit 12c of the unit A is driven at time t0, the pressing of the weight 12b of the unit A is released, the weight 12b is pushed by the pressure in the cooking container 5, and the steam in the cooking container 5 is discharged. When the pressure in the cooking vessel 5 drops to 2.0 atm which is the balance pressure of the unit A, the steam port 12a is closed again by the dead weight of the weight 12b of the unit A, and the pressure in the cooking vessel 5 becomes 2.0 atm. Maintained.

  The control unit 21 drives the discharge adjustment unit 12c of the unit A and then drives the discharge adjustment unit 12c of the unit B after waiting for the elapse of a preset time interval Δt. Thereby, the pressure in the cooking container 5 falls to 1.8 atmospheres. Thereafter, similarly, the control unit 21 sequentially drives the discharge adjustment units 12c of the units C and D every time the time interval Δt elapses. Thereby, the pressure in the cooking vessel 5 falls to atmospheric pressure (1.0 atm) at time t2.

  On the other hand, as shown by the one-dot chain line in FIG. 3, if the weight 10 is moved by operating the pressure adjusting unit 11 and the steam is discharged from the steam port 11a set to a balance pressure of 2.2 atm. At the time t1 earlier than the time t2, the pressure in the cooking vessel 5 decreases to the atmospheric pressure.

(effect)
As described above, in the first embodiment, the steam in the cooking vessel 5 is gradually exhausted by exhausting steam in the order from the steam port 11a having a high balance pressure to the steam port having a low balance pressure in each unit of the steam discharge unit 12. Can be discharged. Moreover, since the discharge | emission adjustment part 12c in each unit of the vapor | steam discharge | emission part 12 is driven sequentially at intervals of time, the pressure in the cooking vessel 5 can be pressure-reduced in steps. Thereby, compared with the case where the weight 10 is shifted by the pressure adjusting unit 11 and the pressure is reduced to atmospheric pressure at once, the amount of steam generated at a time can be reduced to suppress the steam momentum. In addition, it is possible to suppress a sudden pressure change and suppress the possibility of spilling due to bumping.

  In the first embodiment, the case where the discharge adjustment unit 12c in each unit of the steam discharge unit 12 is sequentially operated at a preset time interval Δt has been described, but the present invention is not limited to this.

  For example, the pressure sensor which detects the pressure in the cooking container 5 is provided, the control part 21 acquires the detection result of a pressure sensor, drives the discharge | emission adjustment part 12c of the steam discharge part 12, and then balance pressure of the said unit When it is detected that the discharge adjustment unit 12c has decreased, the discharge adjustment unit 12c of the next unit may be driven. By such an operation, for example, even when the steam generation speed varies depending on the volume or type of the object to be heated and the decompression speed does not become the intended one, the steam is discharged in accordance with the pressure change in the cooking vessel 5. You can control the speed.

  Note that the pressure may be obtained from the correspondence relationship between the saturated steam temperature and the pressure using the detection result of the temperature sensor 4 instead of the detection result of the pressure sensor.

  In addition, in this Embodiment 1, although the case where the steam discharge part 12 was provided with four units AD was demonstrated, the number of units of the steam discharge part 12 is not limited to this, It can be made into arbitrary numbers. .

  In the first embodiment, all the weights 12b of the steam discharge unit 12 have the same weight, and the balance pressure is set according to the difference in the opening area of the steam port 12a. It is not limited. The pressure may be set to be different depending on the combination of the opening area of the steam port 12a and the weight 12b. For example, the opening area of the steam port 12a may be the same and the weight of the weight 12b may be changed. Both the opening area and the weight of the weight 12b may be changed and combined. The shape of the steam port 12a is not limited to a circle. Further, the shape of the weight 12b is not limited to the spherical shape as illustrated.

Embodiment 2. FIG.
FIG. 4 is a schematic cross-sectional view showing a steam discharge part of the heating cooker according to the second embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 30 according to the second embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In FIG. 4, the steam discharge unit 30 communicates with the cooking container 5 through an inner lid steam port 6 a formed in the inner lid 6. The steam discharge unit 30 is provided with an external steam port 34 that communicates with the steam cartridge 15.

  The steam discharge unit 30 includes five units A to E. Each unit of the steam discharge unit 30 includes a steam port 31, a weight 32, and a discharge adjustment unit 33. Hereinafter, when distinguishing the configuration of each unit, the steam ports 31 of the units A, B, C, D, and E are referred to as steam ports 31a, 31b, 31c, 31d, and 31e, respectively. The weights 32 of the units A, B, C, D, and E are referred to as weights 32a, 32b, 32c, 32d, and 32e, respectively. In addition, the discharge adjustment units 33 of the units A, B, C, D, and E are referred to as discharge adjustment units 33a, 33b, 33c, 33d, and 33e, respectively.

  The steam discharge unit 30 has a configuration in which units A, B, C, D, and E are connected. The steam ports 31a to 31e of each unit communicate with each other in series along the steam flow direction. That is, the inner lid steam port 6a of the inner lid 6, the steam ports 31a to 31e, and the outer steam port 34 communicate with each other to form one steam passage for discharging the steam in the cooking vessel 5 to the outside of the main body 1. doing.

  The weight 32 of each unit blocks the steam port 31 movably. The discharge adjusting unit 33 is configured by a solenoid, for example. When the weight 32 is moved from the steam port 31 by the discharge adjusting unit 33, the steam port 31 is opened and the steam passes therethrough.

  In the steam discharge unit 12, each unit has different balance pressures that balance the pressure at which the steam port 31 is blocked by the weight of the weight 32 and the pressure at which the weight 32 is pushed away by the pressure in the cooking container 5. For example, the steam ports 31a to 31e of each unit have different opening areas, and the weights 32a to 32e of each unit all have the same weight.

  Here, the balance pressure of the unit A is maximized, and the units B, C, D, and E are increased in this order. That is, the balance pressure of unit A is the highest and unit E is the lowest. For example, the opening area of the steam port 31a of the unit A is minimized, and the units B, C, D, and E (31b, 31c, 31d, and 31e, respectively) are increased in this order. For example, the balance pressure of the units A to E of the steam discharge unit 30 is set to 2.2, 2.0, 1.8, 1.5, and 1.2 atmospheres.

(Operation)

Next, the operation of the heating cooker according to the second embodiment will be described.
Similar to the first embodiment, the control unit 21 starts a heating operation in accordance with an input from the operation display unit.

  During the heating operation, the control unit 21 drives the discharge adjustment units 33b to 33e of the units B to E, moves the weights 32b to 32e from the steam ports 31b to 31e, and opens the steam ports 31b to 31e. To. That is, only the steam port 31a of the unit A is closed with the weight 32a.

  When the object to be heated in the cooking container 5 is heated, steam is generated from the object to be heated. When steam is generated from the object to be heated, the steam flows from the inner lid steam port 6a of the inner lid 6 to the steam discharge unit 30 and passes through the steam ports 31e, 31d, 31c, and 31b in this order. The steam that has reached the steam port 31a of the unit A is prevented from being discharged by the pressure of the weight 32a that blocks the steam port 31a. Thereby, pressure is applied in the cooking container 5. When the pressure in the cooking vessel 5 rises above the pressure that blocks the steam port 31a by the weight of the weight 32a, the weight 32a is pushed away from the steam port 31a by the pressure in the cooking vessel 5. When the weight 32a is pushed away from the steam port 31a, the steam in the cooking container 5 is discharged, the pressure in the cooking container 5 decreases, and the steam port 31a is closed again by the weight of the weight 32a. Thus, during cooking, the pressure in the cooking vessel 5 is maintained so as not to exceed the balance pressure of unit A (for example, 2.2 atmospheres). Thus, the unit A also functions as a pressure adjusting unit that adjusts the pressure during the heating operation.

  When the cooking is finished, the control unit 21 stops the operation of the inverter unit 22. Even after the heating is finished, the steam port 31a of the unit A is blocked by the dead weight of the weight 32a, and the pressure in the cooking vessel 5 is kept higher than the atmospheric pressure.

  When discharging the steam in the cooking container 5 after cooking, the control unit 21 moves the weight 32b to the steam port 31b and closes the steam port 31b by the discharge adjusting unit 33b of the unit B. And the control part 21 moves the weight 32a from the steam port 31a by the discharge | emission adjustment part 33a of the unit A, and makes the steam port 31a open. That is, only the steam port 31b of the unit B is blocked by the weight 32b.

  Thereby, the weight 32b is pushed away by the pressure in the cooking vessel 5, and the steam in the cooking vessel 5 is discharged. When the pressure in the cooking vessel 5 drops to 2.0 atm which is the balance pressure of the unit B, the steam port 31b is closed again by the dead weight of the weight 32b of the unit B, and the pressure in the cooking vessel 5 becomes 2.0 atm. Maintained.

  Next, the control unit 21 moves the weight 32c to the steam port 31c and closes the steam port 31c by the discharge adjusting unit 33c of the unit C. And the control part 21 moves the weight 32b from the steam port 31b by the discharge | emission adjustment part 33b of the unit B, and makes the steam port 31b open. That is, only the steam port 31c of the unit C is closed with the weight 32c.

  Thereby, the weight 32c is pushed away by the pressure in the cooking vessel 5, and the steam in the cooking vessel 5 is discharged. When the pressure in the cooking vessel 5 decreases to 1.8 atm which is the balance pressure of the unit C, the steam port 31c is closed again by the dead weight of the weight 32c of the unit C, and the pressure in the cooking vessel 5 becomes 1.8 atm. Maintained.

  Thereafter, similarly, the discharge adjusting unit 33 is operated in the order of the units D and E, and the steam in the cooking container 5 is gradually discharged. In this manner, in each unit of the steam discharge unit 30, the weight 32 is moved to the steam port 31 in order from the unit with the highest balance pressure to the lowest.

  As in the first embodiment, the discharge adjustment unit 33 of each unit is driven with a time interval, and the weight 32 of each unit is moved sequentially with a time interval. Further, as described above, a pressure sensor for detecting the pressure in the cooking container 5 may be provided, and the weight 32 of each unit may be moved sequentially in accordance with the detection result of the pressure sensor.

(effect)
As described above, in the second embodiment, the plurality of steam ports 31 are formed along the flow direction of the steam, and the weights 32 are arranged in the order from the unit with the higher balancing pressure to the unit with the lower unit in each unit of the steam discharge unit 30. The steam in the cooking vessel 5 can be gradually discharged by moving and closing the steam to the steam port 31. Moreover, since the discharge | emission adjustment part 33 in each unit of the vapor | steam discharge | emission part 30 is driven sequentially at intervals of time, the pressure in the cooking vessel 5 can be pressure-reduced in steps. Thereby, compared with the case where it decompresses to atmospheric pressure at a stretch, the quantity of the vapor | steam generated at once can be decreased and the vigor of vapor | steam can be suppressed. In addition, it is possible to suppress a sudden pressure change and suppress the possibility of spilling due to bumping.

  In addition, in this Embodiment 2, although the case where the vapor | steam discharge part 30 was provided with five units AE was demonstrated, the number of units of the vapor | steam discharge part 30 is not limited to this, It can be made into arbitrary numbers. . Further, in FIG. 4, each unit of the steam discharge unit 30 is connected in the vertical direction, but it is sufficient that the units are connected to each other, and the shape is not limited to this, and the units are arranged in the oblique direction even if they are arranged horizontally. May be. For example, if they are arranged in the horizontal direction, the height of the main body 1 can be suppressed, which is convenient.

  In the second embodiment, all the weights 32 of the steam discharge unit 30 have the same weight, and the balance pressure is set according to the difference in the opening area of the steam port 31. It is not limited. It is only necessary to set different pressures depending on the combination of the opening area of the steam port 31 and the weight 32. For example, the opening area of the steam port 31 may be equal and the weight 32 may be changed. Both the opening area and the weight of the weight 32 may be changed and combined. Further, the shape of the steam port 31 is not limited to a circle. Further, the shape of the weight 32 is not limited to the spherical shape as illustrated.

Embodiment 3 FIG.
FIG. 5 is a schematic cross-sectional view showing a steam discharge part of the heating cooker according to the third embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 40 according to the third embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In FIG. 5, the steam discharge unit 40 communicates with the cooking container 5 through an inner lid steam port 6 a formed in the inner lid 6. Further, the steam discharge unit 40 is provided with an external steam port 44 to which the steam cartridge 15 is connected.

  The steam discharge unit 40 includes four units A to D. Each unit of the steam discharge unit 40 includes a steam port 41, a weight 42, and a discharge adjustment unit 43. Hereinafter, when the configurations of the units are distinguished, the steam ports 41 of the units A, B, C, and D are referred to as steam ports 41a, 41b, 41c, and 41d, respectively. The weights 42 of the units A, B, C, and D are referred to as weights 42a, 42b, 42c, and 42d, respectively. In addition, the discharge adjustment units 43 of the units A, B, C, and D are referred to as discharge adjustment units 43a, 43b, 43c, and 43d, respectively.

  The steam discharge unit 40 has a configuration in which units A, B, C, and D are connected. The steam ports 41a to 41d of each unit communicate in series along the steam flow direction. That is, the inner lid steam port 6 a of the inner lid 6, the steam ports 41 a to 41 d, and the outer steam port 44 communicate with each other to form one steam passage that discharges the steam in the cooking container 5 to the outside of the main body 1. doing.

  The weight 42 of each unit blocks the steam port 41 movably. The discharge adjusting unit 43 is configured by a solenoid, for example. When the weight 42 is moved from the steam port 41 by the discharge adjusting unit 43, the steam port 41 is opened and the steam passes through. In addition, in FIG. 5, although the discharge | emission adjustment part 43 is arrange | positioned to the side of the weight 42 for description, this invention is not limited to this. For example, the discharge adjustment unit 43 may be positioned on the near side of the weight 42 and may be driven to shift the weight 42 toward the back and open the steam port 41.

  In the steam discharge unit 40, each unit has a balance pressure in which the pressure at which the steam port 41 is blocked by the weight of the weight 42 and the pressure at which the weight 42 is pushed away by the pressure in the cooking container 5 are balanced. For example, the vapor openings 41a to 41d of each unit have the same opening area, and the weights 42a to 42d of each unit have different weights.

  Further, a total value obtained by adding the total of the balance pressures of each unit and the atmospheric pressure (1.0 atm) is set to, for example, the upper limit value (for example, 2.2 atm) of the pressure in the cooking vessel 5. For example, the balance pressure of unit A is set to 0.1 atmosphere. The balance pressure of unit B is set to 0.2 atm. The balance pressure of unit C is set to 0.4 atm. The balance pressure of unit D is set to 0.5 atm.

(Operation)
With such a configuration, the units of the steam discharge unit 40 are connected in series along the direction of steam flow, so the pressure applied in the cooking vessel 5 is the balance pressure of the units closed by the weights 42. It becomes the value which added atmospheric pressure to the total of. That is, when the steam port 41a of the unit A and the steam port 41b of the unit B are closed with the weight 42a and the weight 42b, respectively, the total of 0.1 atm and 0.2 atm, and the atmospheric pressure are 1. The total pressure of 0 atm, 1.3 atm, is balanced with the pressure in the cooking vessel 5.

  Thus, the pressure of the steam discharged from the cooking container 5 by changing the combination of the steam port 41 that moves the weight 42 and the steam port 41 that does not move the weight 42 among the steam ports 41 of the plurality of units. Adjust. In the example of the balance pressure of each unit described above, the pressure can be adjusted in increments of 0.1 atm from 1.1 to 2.2 atm by combining the presence / absence of driving of the discharge adjusting unit 43 of each unit.

  In addition, by setting the total value of the balance pressure and the atmospheric pressure in a state where all the steam ports 41 of the units A to D are closed with the weight 42, for example, the upper limit value of the pressure in the cooking vessel 5 is set. The discharge unit 40 also functions as a pressure adjusting unit that adjusts the pressure during the heating operation.

  As in the first embodiment, the discharge adjustment unit 43 of each unit is driven with a time interval, and the weights 42 of each unit are sequentially moved with a time interval. Further, as described above, a pressure sensor for detecting the pressure in the cooking container 5 may be provided, and the weight 42 of each unit may be sequentially moved according to the detection result of the pressure sensor.

(effect)
As described above, in the third embodiment, in addition to the effects of the first and second embodiments, a large number of pressure limiting steps can be obtained with a small number of units, and the main body 1 can be reduced by reducing the number of units. Can do.

  In addition, in this Embodiment 3, although the case where the steam discharge part 40 was provided with four units AD was demonstrated, the number of units of the steam discharge part 40 is not limited to this, It can be made into arbitrary numbers. . In FIG. 5, the units of the steam discharge unit 40 are connected in the vertical direction. However, the units are not limited to this as long as they are connected to each other, and the units are arranged in an oblique direction even if they are arranged side by side. May be. For example, if they are arranged in the horizontal direction, the height of the main body 1 can be suppressed, which is convenient.

  Further, for example, if the pressures of the units are set so that the pressures when the balancing pressures in each unit are combined are all different, it is possible to obtain many pressure limiting steps with a small number of units. As in the first and second embodiments, the opening area of the steam port 41 and the weight of the weight 42 can be arbitrarily set.

Embodiment 4 FIG.
FIG. 6 is a schematic cross-sectional view showing a steam discharge part of the heating cooker according to the fourth embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 50 according to the fourth embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In FIG. 6, the steam discharge part 50 has one steam port 51 formed therein. The steam port 51 communicates with the cooking vessel 5 through an inner lid steam port 6 a formed in the inner lid 6. Further, the steam discharge unit 40 is provided with an external steam port 55 to which the steam cartridge 15 is connected.

  The steam discharge unit 50 includes five units A to E. Each unit of the steam discharge unit 50 includes a weight 52 and a discharge adjustment unit 43. The weight 52 of each unit is arranged so as to be subjected to a cumulative load of gravity and closes one steam port 51. For example, as shown in FIG. The discharge adjustment unit 53 is configured by a solenoid, for example. A weight receiving portion 54 is formed on the side of each weight 52. As shown in FIG. 6B, when the weight 52 is moved onto the weight receiving portion 54 by the discharge adjusting portion 53, the load of the weight 52 is received by the weight receiving portion 54.

(Operation)
With this configuration, the steam discharge unit 50 adjusts the balance pressure at the steam port 51 according to the number of weights 52 that block the one steam port 51. When the steam in the cooking container 5 is discharged, the control unit 21 drives the discharge adjusting unit 53 in order from the uppermost unit A toward the lower unit, and sequentially shifts the weights 52. As a result, the weight applied to one steam port 51 decreases in a stepwise manner, and steam is discharged until the pressure reaches a balance between the opening area of the steam port 51 and the total weight applied to the steam port 51.

  In addition, the steam discharge part 40 is heated by setting the balance pressure in the state which block | closed the one steam port 51 with all the weights 52 of units AE to the upper limit of the pressure in the cooking vessel 5, for example. It also functions as a pressure adjustment unit that adjusts the pressure during operation.

  As in the first embodiment, the discharge adjustment unit 53 of each unit is driven with a time interval, and the weights 52 of each unit are sequentially moved with a time interval. Further, as described above, a pressure sensor for detecting the pressure in the cooking vessel 5 may be provided, and the weight 52 of each unit may be moved sequentially in accordance with the detection result of the pressure sensor.

(effect)
As described above, in the fourth embodiment, the pressure of steam discharged from the cooking container 5 is adjusted by changing the number of weights 52 that block one steam port 51. For this reason, the pressure in the cooking vessel 5 can be gradually reduced, and the same effect as in the first embodiment can be obtained.

  In addition, the number of units of the vapor | steam exhaust part 50 can be made into arbitrary numbers. Further, the shape of the weight 52 is not limited to the sphere as illustrated. In FIG. 6, one discharge adjustment unit 53 is provided for each weight 52, but a plurality of weights 52 may be moved by one discharge adjustment unit 53, for example.

Embodiment 5. FIG.
FIG. 7 is a schematic cross-sectional view showing a steam discharge part of the heating cooker according to the fifth embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 60 according to the fifth embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In the fifth embodiment, the pressure adjusting unit 11 for moving the weight 10 described in the first embodiment is provided separately from the steam discharging unit 60, and the pressure is adjusted by discharging the steam from the steam port 11a. A configuration may be provided.

  The steam discharge unit 60 according to the fifth embodiment includes four units A to D. Each unit of the steam discharge unit 60 includes a steam port 61, a weight 62, a discharge adjustment unit 63, and a discharge port 64. The steam port 61 of each unit communicates with the inner lid steam port 6 a of the inner lid 6, and forms a steam passage through which the steam in the cooking container 5 is discharged from the discharge port 64 to the outside of the main body 1. The weight 62 blocks the steam port 61 in a movable manner. The discharge adjustment unit 63 is configured by a solenoid, for example.

Among the steam ports 61 of each unit, the opening area of at least one steam port 61 is formed to be different from the opening areas of the other steam ports 61. For example, the steam port 61 of the unit A and the unit B is formed with φ0.36 mm (0.1 mm ² ), and the steam port 61 of the unit C and the unit D is formed with φ0.62 mm (0.3 mm ² ). Yes.

(Operation)
With such a configuration, by changing the combination of the steam port 61 that moves the weight 62 and the steam port 61 that does not move the weight 62 among the four units A to D, the opening area of the opened steam port 61 is changed. The pressure of the steam discharged from the cooking vessel 5 is adjusted by changing the sum of the above. For example, the control unit 21 first opens one steam port 61 of the unit A, and discharges the steam from the steam port 61 having an opening area of 0.1 mm ² . Thereafter, the two steam ports 61 of the unit A and the unit B are opened so that the total opening area becomes 0.2 mm ² . Next, only the steam port 61 of the unit C is opened, and the opening area is set to 0.3 mm ² . Then, in addition to the unit C, the unit A or B is opened to make the opening area 0.3 mm ² . Thus, by changing the combination of the steam outlet 61 to open, to 0.1 to 0.8 mm ^2, gradually 0.1 mm ² increments, can be expanded the total opening area of the vapor outlet 61 It has become a structure.

  As described above, in the fifth embodiment, in the units A to D of the steam discharge unit 60, the combination of the steam port 61 that moves the weight 62 and the steam port 61 that does not move the weight 62 is changed, so that the total The opening area of is gradually enlarged step by step. Thereby, the steam in the cooking vessel 5 can be gradually released outside while adjusting the discharge amount of the steam. Further, by gradually widening the opening area, the amount of steam generated at a time can be reduced and the steam momentum can be suppressed as compared with the case where the pressure is reduced to atmospheric pressure at once. In addition, it is possible to suppress a sudden pressure change and suppress the possibility of spilling due to bumping.

  In addition, the shape of the steam port 61 can be made into arbitrary shapes. In addition, if the steam port 61 can be opened and closed while ensuring hermeticity, the steam port 61 is not closed by the weight 62, and for example, a spring, a shape memory alloy, or a screw may be used. The lid | cover which covers may be set so that it may open | release with a pressure higher than the pressure regulation part 11. FIG.

  In addition, a sound is generated when the steam passes through the steam port 61. However, the scale may be adjusted by adjusting the opening area of the steam port 61 or may be used as a lid opening signal.

Embodiment 6 FIG.
FIG. 8 is a schematic cross-sectional view showing a steam discharge part of the heating cooker according to the sixth embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 70 in the sixth embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In the sixth embodiment, the pressure adjusting unit 11 for moving the weight 10 described in the first embodiment is provided separately from the steam discharging unit 70, and the pressure is adjusted by discharging the steam from the steam port 11a. A configuration may be provided.

  The steam discharge unit 70 according to the sixth embodiment includes a steam port 71, a screw-type lid 72 that is an area variable unit, and a discharge adjustment unit 73. The steam port 71 is configured by a cylindrical body disposed around the inner lid steam port 6 a of the inner lid 6. The steam port 71 forms a steam passage through which steam discharged from the inner lid steam port 6a flows. The screw-type lid 72 has, for example, a conical shape at the tip, and is inserted into the steam port 71 to change the opening area of the steam passage of the steam port 71. Further, the screw type lid 72 moves with respect to the steam port 71 to change the opening area of the steam passage of the steam port 71. The discharge adjusting unit 73 is configured by a motor, for example. The discharge adjusting unit 73 rotates the screw-type lid 72 via a gear to move it upward. Thereby, the area (opening area of the steam passage) between the screw-type lid 72 and the steam port 71 is varied.

(Operation)
With such a configuration, the steam discharge unit 70 adjusts the pressure of the steam discharged from the cooking vessel 5 by gradually increasing the opening area of the steam passage of the steam port 71 by moving the screw-type lid 72. To do. The screw-type lid 72 completely closes the steam port 71 when positioned at the lowest position. When the pressure in the cooking container 5 is reduced, the control unit 21 drives the discharge adjustment unit 73 to move the screw type lid 72 upward. The screw-type lid 72 has a shape that narrows toward the lower part, and a gap is formed between the screw-type lid 72 and the wall surface of the steam port 71 by moving upward in the steam port 71, and from this gap Steam is discharged.

  As described above, in the sixth embodiment, the opening area of the steam port 71 can be gradually increased stepwise. Therefore, the same effect as in the fifth embodiment can be obtained.

  In the sixth embodiment, the configuration in which the steam port 71 is closed by the screw-type lid 72 has been described, but the present invention is not limited to this. Any configuration that can gradually expand the opening area of the steam port 71 may be used. Further, the operation of the screw type lid 72 is not limited to the vertical direction. Further, not limited to the screw-type lid 72, for example, a method of enlarging the opening of the steam port 71 by shifting a lid that closes the steam port 71 to the side may be used.

Embodiment 7 FIG.
FIG. 9 is a schematic cross-sectional view schematically showing the configuration of the heating cooker according to the seventh embodiment.
Hereinafter, the configuration and operation of the steam discharge unit 80 according to the seventh embodiment will be described focusing on differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the same part.

  In FIG. 9, the steam discharge unit 80 includes a steam port 81, a weight 82, and a discharge adjustment unit 83. The steam port 81 is provided through the inner lid 6 and communicates with the in-lid communication path 18. The weight 82 blocks the steam port 81 movably. The balance pressure by the weight 82 and the steam port 81 is set to the upper limit value (for example, 2.2 atmospheres) of the pressure in the cooking vessel 5, for example. The discharge adjustment unit 83 moves the weight 82. The discharge adjusting unit 83 is constituted by a solenoid, for example. When the weight 82 is moved from the steam port 81 by the discharge adjusting unit 83, the steam port 81, the in-lid communication path 18, and the external steam port 9 communicate with each other, and the steam in the cooking container 5 is outside the main body 1. Is discharged.

(Operation)
With such a configuration, the steam discharge unit 50 intermittently switches between a state in which the steam port 81 is blocked with the weight 82 and a state in which the weight 82 is moved from the steam port 81 to be opened. Thereby, the vapor | steam in the cooking container 5 is discharged | emitted gradually. For example, after the discharge adjustment unit 83 is driven and the steam port 81 is opened for 1 second, the drive of the discharge adjustment unit 83 is released and closed for 5 seconds. In this way, steam discharge is executed at a preset time.

  As described above, in the seventh embodiment, the amount of steam discharged at one time can be limited by adjusting the opening time of the steam port 81. Therefore, the steam in the cooking vessel 5 can be gradually released to the outside while adjusting the discharge amount of the steam. Further, by gradually widening the opening area, the amount of steam generated at a time can be reduced and the steam momentum can be suppressed as compared with the case where the pressure is reduced to atmospheric pressure at once. In addition, it is possible to suppress a sudden pressure change and suppress the possibility of spilling due to bumping.

  Note that the time for opening the steam port 81 may be gradually increased. Thereby, an open time can be extended and steam discharge | emission can be promoted, so that the pressure in the cooking container 5 approaches atmospheric pressure. Therefore, it is possible to quickly reduce the pressure while limiting the steam discharge amount.

  Furthermore, the setting of the time for opening the steam port 81 may be changed according to the pressure in the cooking vessel 5 detected by the pressure sensor 84. For example, the opening time of the steam port 81 may be shortened as the pressure increases, and the opening time may be set longer as the pressure decreases.

  Note that the pressure may be obtained from the correspondence between the saturated steam temperature and the pressure using the detection result of the temperature sensor 4 instead of the detection result of the pressure sensor 84 described above.
