  5 and 6 show the structure of the shutter 31 described above. In the figure, the shutter 31 includes a cap 71 attached to the outlet 23 of the three-way valve 21, a shaft portion 74 provided on the top plate 73 that forms the upper surface portion of the receiving portion 28, and a rotation around the shaft portion 74.

When the current supplied to each electromagnet 78, 79 is controlled so that the magnet 75 is attracted to one electromagnet 78, the opening / closing body 77 closes the communication portion 80, and conversely, the magnet 75 is attached to the other electromagnet 79. When the current supplied to the electromagnets 78 and 79 is controlled so as to be attracted, the opening / closing body 77 moves away from the communication portion 80, and the outlet 23 of the three-way valve 21 and the discharge port 29 formed in the top plate 73 communicate with each other. It is like that.

  Next, the electrical configuration of the cooking device in the present embodiment will be described with reference to FIG. In the same figure, the temperature detection means 41 and the operation part 55 are connected to the input port of the control means 51, respectively, and the heating coil 7, the pump 11, the three-way valve 21 and the like are connected to the output port of the control means 51. The discharge opening valve 45, the decompression pump 47, the display unit 56, and the electromagnets 78 and 79 are connected to each other. And the control means 51 receives the detection signal from the temperature detection means 41 and the operation signal from the operation part 55, and performs the cooking control means 81 which controls each part connected to the output port at the time of cooking, and after cooking. The temperature control means 82 for controlling each part connected to the output port is provided. In addition, what kind of control the heat cooking control means 81 and the heat retention control means 82 perform concretely is demonstrated in detail later.

  Next, the operation will be described with reference to the flowchart of FIG.

  The lid body 2 is opened, soup material is put into the container 4 from above the main body 1, the lid body 2 is closed, and the lid body 2 is kept closed by a lock mechanism. In addition, as a soup material, what was thawed to about room temperature with the microwave oven etc. what was cooked beforehand and frozen and preserve | saved may be used. Next, the heat retention temperature of the soup is selected with the temperature setting button 62, and the viscosity of the soup charged into the container 4 is selected with the viscosity setting button 61. Specifically, each time the temperature setting button 62 is pressed, the temperature display LEDs 68 corresponding to “70” → “80” → “90” → “70” are sequentially lit, and the selected heat retention temperature is sent to the control means 51. Settings are stored. Similarly, each time the viscosity setting button 61 is pressed, the viscosity display LEDs 67 corresponding to “low” → “medium” → “high” → “low” are sequentially lit, and the viscosity of the selected soup is set in the control means 51. Remembered.

  Incidentally, the liquid soup is put in a cup with the ingredients, stored and placed in the receiving portion 28, and the soup in the container 4 is discharged into the cup containing the ingredients. There are various types of soups, such as those with low viscosity such as consomme soup, and those with high viscosity such as potage soup. Is selected, the cooking control unit 81 performs optimum cooking. Here, it is preferable to select a “low” viscosity for a low-viscosity soup such as consomme soup, and to select a “high” viscosity for a high-viscosity soup such as potage soup.

  When the heat retention temperature and the soup viscosity are set in this way, the operation / stop button 58 is pushed to perform the cooking process by the cooking control unit 81. In this cooking process, the heating coil 7 is energized continuously to heat the soup material in the container 4 until the temperature detected by the temperature detection means 41 reaches a predetermined value. During cooking, the cooking controller 81 supplies a switching signal to the three-way valve 21 so that the inflow port 22 and the outflow port 24 communicate with each other and opens an operation signal for opening the exhaust passage 42 at the time of discharge. It supplies to the valve 45, and the steam etc. which generate | occur | produce from the soup in the container 4 during cooking are discharged to the exhaust port 44 via the exhaust passage 42. Here, the cooking control means 81 operates the pump 11 so that the soup is circulated by the circulation path 37 and the soup in the container 4 is agitated so as not to cause problems such as scorching. The whole can be heated uniformly.

  As shown in FIG. 8, in order to effectively stir the soup in the container 4, the pump 11 is turned off and on for a predetermined time. Is not particularly limited. For example, the energizing time and the disconnecting time of the pump 11 may be varied according to the soup viscosity set by the viscosity setting button 61.

  During cooking, it is not necessary to depressurize the inside of the container 4, and the decompression pump 47 is maintained in the off state by the cooking control unit 81. During cooking, the inlet 22 and the outlet 24 are communicated with each other by the three-way valve 21 and the discharge path 30 is closed by the shutter 31 for preventing the back sag. Preferably, even when the discharge button 59 is pushed, the cooking control means 81 may not accept this, and soup may not be discharged from the discharge port 29.

  When the detected temperature of the container 4 reaches a predetermined temperature, the cooking process by the cooking control unit 81 is finished, and instead, the process proceeds to a heat retaining process by the heat retaining control unit 82. In this heat retention step, the heat retention control means 82 controls the heating coil 7 to be disconnected so that the detected temperature of the container 4 approaches the heat retention temperature set in advance by the temperature setting button 62. When the process proceeds to the heat retaining step, an operation signal for closing the exhaust passage 42 is supplied from the heat retaining control means 82 to the discharge opening valve 45, and the soup in the container 4 is shut off from the outside air. The heat retaining control means 82 continues to block the exhaust passage 42 unless a pushing operation of the discharge button 59 described later is performed.

  In this state, the heat retention control means 82 supplies a drive signal for operating the decompression pump 47 for a predetermined time to the decompression pump 47. As described above, since the exhaust passage 42 is closed by the discharge opening valve 45, when the pressure reducing pump 47 is operated, the pressure in the container 4 that has been in the normal pressure state until then gradually decreases. Thus, during the heat insulation, the inside of the container 4 is depressurized to reduce the oxygen concentration with respect to the container space volume in the container 4, so that the oxidative deterioration of the soup can be reduced and the soup can be kept delicious for a long time. . In addition, since the warming time of the soup becomes longer, the amount of surplus soup discarded can be reduced, reducing the trouble associated with disposal and the loss of soup disposal.

  Further, the heat escape from the container 4 is reduced by the heat insulating materials 48 and 49. Therefore, the power consumption of the heating coil 7 can be mainly reduced during the heating cooking process and the heat retaining process, and energy loss as a cooking device can be reduced. In particular, by using a vacuum heat insulating material as the heat insulating materials 48 and 49, heat escape from the container 4 can be more effectively reduced. Therefore, at the time of a heating cooking process or a heat retention process, mainly the power consumption of the heating coil 7 can be further reduced, and the energy loss as a cooking device can be effectively reduced.

  As shown in FIG. 8, the heat retention control means 82 operates the drive pump 47 repeatedly at regular intervals. The repeated constant time and the operation time of the drive pump 47 are slow leaks when the inside of the container 4 is depressurized. It may be set as appropriate in consideration of the degree of the above.

  Further, the heat retaining control means 82 supplies a switching signal to the three-way valve 21 so that the inflow port 22 and the outflow port 24 are in communication unless the discharge button 59 is pushed. Therefore, when the pump 11 is operated in this state, the soup is circulated by the circulation path 37, the soup in the container 4 is stirred, and the whole soup in the main body 1 can be kept warm. In this case as well, there is no particular limitation on how long the energization time and the disconnection time of the pump 11 are set. In this embodiment, regardless of the process, the circulation path 37 is always in communication, and the discharge path 30 is in communication only when the discharge button 59 is operated, so that soup is discharged from the discharge port 29. It has become.

  When discharging the soup while keeping the temperature, when the discharge button 59 is pressed, the discharge amount of the soup preset and stored by the discharge amount setting button 60 is discharged from the discharge port 29. The discharge amount can be switched by the discharge amount setting button 60, and the heat retention control means 82 determines the drive time of the pump 11 according to the set discharge amount. Specifically, the driving time of the pump 11 may be lengthened as the set discharge amount increases. In response to the operation signal when the discharge button 59 is pushed, the heat retaining control means 82 supplies a switching signal to the three-way valve 21 so that the inlet 22 and the outlet 23 communicate with each other, and the outlet of the three-way valve 21. The electric current is supplied to the electromagnets 78 and 79 and the drive signal is supplied to the pump 11 so that the discharge port 29 and the discharge port 29 communicate with each other. As a result, the drive pump 11 is operated, and the soup in the container 4 is discharged to the cup placed and accommodated in the receiving portion 28 via the discharge path 30.

  In this embodiment, as the pump 11 for sucking out the soup in the container 4 to the outside of the container 4, a tube pump capable of discharging a high-viscosity liquid is used, so that various types from a low-viscosity soup to a high-viscosity soup are used. However, even if the pump 11 is operated for a driving time corresponding to the discharge amount, the discharge amount changes depending on the viscosity of the soup. Therefore, a viscosity setting button 61 for setting the soup viscosity is provided to set the discharge amount. The heat retention control means 82 determines the drive time of the pump 11 in accordance with not only the discharge amount set with the button 60 but also the soup viscosity set with the viscosity setting button 61. That is, in the tube pump as the pump 11, the amount of liquid outflow per unit time decreases as the soup viscosity increases, and conversely when the soup viscosity decreases, the amount of liquid outflow per unit time increases. Therefore, the heat retention control means 82 increases the drive time of the selected soup as the viscosity of the selected soup increases with respect to the drive time of the pump 11 determined according to the set discharge amount. As the viscosity decreases, the drive time of the pump 11 is shortened, so that the supply amount of soup finally discharged from the discharge port 29 can be made constant regardless of the viscosity. Further, when discharging soup, the exhaust passage 42 is opened by the discharge opening valve 45 and the inside of the container 4 is at the same atmospheric pressure (atmospheric pressure) as the outside air, so that the soup can be discharged smoothly by the pump 11.

  Thereafter, when a certain amount of soup is discharged from the discharge port 29 and the heat retaining control means 82 stops the operation to the pump 11, the shutter 31 is connected between the outlet 23 and the discharge port 29 of the three-way valve 21 in conjunction therewith. Current is supplied to the electromagnets 78 and 79 so that the discharge path 30 is blocked. As a result, so-called sag after the soup remaining in the discharge path 30 hangs down from the discharge port 29 can be prevented, and contamination of a portion where the cup of the receiving portion 28 is placed under the discharge port 29 can be prevented. This also saves the trouble of wiping off the spilled soup from the outlet 29 each time soup is discharged.

  Further, since the exhaust passage 42 is opened when the soup is discharged and the pressure in the container 4 returns to the atmospheric pressure, the discharge passage 42 is closed by the discharge opening valve 45 after the soup is discharged, and the decompression pump 47 is turned on for a predetermined time. By operating, the inside of the container 4 is again decompressed to a state below atmospheric pressure. Thereby, the inside of the container 4 can be maintained in a reduced pressure state as much as possible at the time of heat retention.

  Next, the cleaning process performed by the control means 51 will be described. When cleaning is performed, when a cleaning liquid such as water or warm water is put in the container 4 in advance and the self-cleaning button 63 is pushed, a cleaning process by the control means 51 is started. In this cleaning step, the cleaning liquid is heated by the heating coil 7 until the cleaning liquid in the container 4 reaches a predetermined temperature or while the pump 11 is operated in a state where the circulation path 37 is in communication for a predetermined time. The inside of the container 4 and the circulation path 37 is cleaned. Thereafter, the three-way valve 21 is switched so that the discharge path 30 communicates, and the cleaning liquid is discharged from the discharge port 29 to clean the inside of the discharge path 30. When cleaning, a water receiving container is installed under the discharge port 29 or a drain hose is connected to the discharge port 29. The container 4 is not provided with a stirring member for stirring the object to be cooked, and it is not necessary to wash the stirring member. Therefore, cleaning can be performed very easily by executing the cleaning process. it can.

  As described above, in this embodiment, the container 4 provided in the main body 1, the pump 11 serving as a discharge means for discharging the food to be cooked in the container 4 to the outside of the container 4, and the main body 1, and the inside and outside of the container 4 communicate with each other. Alternatively, the operation of the pump 11 serving as the predetermined means and the operation of the discharge open valve 45 so that the inside / outside of the container 4 which is the predetermined portion is communicated with the opening / closing valve 45 serving as the container opening / closing means to be closed. And a control means 51 for controlling, comprising a decompression pump 47 as a transformer means for transforming the inside of the container 4 by, for example, decompression, etc., and the control means 51 reduces the pressure while the inside and outside of the container 4 are closed. The decompression pump 47 is controlled so that the pump 47 operates.

  That is, the inside and outside of the container 4 are closed by the discharge opening valve 45 that is a container opening / closing means, and the pressure reduction pump 47 is operated to decompress the inside of the container 4, thereby reducing the amount of oxygen in the container 4 and Deterioration due to oxidation of the food can be prevented. Therefore, it is possible to reduce the deterioration of the object to be cooked during the heat retention, which is a predetermined time, and to keep the heat for a long time.

  Further, in this embodiment, a discharge path 30 is provided as a path from the inside of the container 4 to the outside of the container 4 which is a predetermined portion, and preferably at the discharge port 29 of the discharge path 30 for preventing a back sag as a path opening / closing means.

In other words, since the control means 51 can individually control the operation of the tube pump according to the type of food to be cooked selected by the viscosity setting button 61, a certain amount of food to be cooked is available for any type of food to be cooked. The food can be reliably discharged outside.

  Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the part which is common in 1st Example, and description of a common location is abbreviate | omitted as much as possible to avoid duplication.

  In this embodiment, the configuration of the operation / display PC board unit 53 is different from that of the first embodiment. Hereinafter, the difference will be described. Here, as the operation unit 55, the operation / stop button 58, the discharge button 59, the discharge amount button 85, the heat retention temperature button 86, the menu button 87, the self-cleaning button 63, and the first switching button 88 are described. , A second switching button 89, and an operation confirmation LED 65, a discharge amount display unit 91, a temperature display unit 92, a menu display unit 93, and a remaining cleaning time display unit 95 as the display unit 56. In the operation unit 55, the operation / stop button 58, the discharge button 59, and the self-cleaning button 63 are the same as those in the first embodiment, but the discharge amount button 85 discharges the food to be cooked from the discharge port 29. When the first switching button 88 or the second switching button 89 is pressed following the pressing operation of the discharge amount button 85, the setting is stored in the control means 51. When the discharge amount of the cooking object is increased or decreased stepwise, and the discharge amount button 85 is pushed again in this state, the increased or decreased discharge amount is set and stored in the control means 51. The heat insulation temperature button 86 is pushed when changing the heat insulation temperature of the cooking object in the container 4. Following the push operation of the heat insulation temperature button 86, the first switching button 88 or the second switching button is used. When the operation 89 is pushed, the heat retention temperature of the cooking object set and stored in the control means 51 is increased or decreased stepwise, and when the heat retention temperature button 86 is pushed again in this state, the increased or decreased heat retention temperature is controlled. The setting is stored in the means 51. The menu button 87 is pushed when changing the menu according to the type of food (soup) to be cooked. Following the pushing operation of the menu button 87, the first switching button 88 or the second switching button is used. When the operation button 89 is pushed, the cooking menu set and stored in the control means 51 is switched. When the menu button 87 is pushed again in this state, the changed cooking menu is set and stored in the control means 51. .

  When the operation / stop button 58 in this embodiment is pushed while discharging the food to be cooked from the discharge port 29, the operation of the pump 11 is interrupted via the control means 51 to forcibly discharge the food to be cooked. It also has a function as an operating means for stopping automatically. Although an independent switch, button, or the like may be provided as the operation means, in order to simplify the operation unit 55, it is preferable to use an operation body having another function such as the run / stop button 58. Incidentally, the control means 51 is configured to accept operation and stop as a cooker by an operation signal from the operation / stop button 58 in cases other than discharging the food to be cooked from the discharge port 29.

  On the other hand, the operation confirmation LED 65 in the display unit 56 is the same as that in the first embodiment, so that it will not be described here, but the discharge amount display unit 91 is to be cooked and set by the control means 51. The temperature display unit 92 displays the heat-retaining temperature of the cooking object set and stored by the control means 51, and corresponds to the discharge amount display LED 66 of the first embodiment. This corresponds to the temperature display LED 68 of one embodiment. The menu display section 93 displays the cooking menu set and stored by the control means 51. As an example, in FIG. 9, a cooking menu of “consomme soup” is displayed. The remaining cleaning time display unit 95 is lit during execution of the cleaning process and displays the remaining time, and also partially functions as the self-cleaning confirmation LED 69 in the first embodiment.

  As described in the first embodiment, the operation unit 55 and the display unit 56 here are merely examples, and can be appropriately changed. The configuration of each other part is the same as that described in the first embodiment.

  Next, the operation of the above configuration will be described. The soup material is put into the container 4, the lid body 2 is closed, and the lid body 2 is kept closed by the lock mechanism. Next, the type of the soup is set in the cooking menu. The temperature of the soup is selected with the temperature setting button 62, and the viscosity of the soup charged into the container 4 is selected with the viscosity setting button 61. In this embodiment, when the menu button 87 is pushed, the menu display section 93 blinks to indicate that the cooking menu input corresponding to the soup type can be changed. Next, the first switching button 88 or the second switching button 89 is pushed to change the cooking menu displayed on the menu display section 93 in order, and when the desired cooking menu is displayed, the menu button 87 is pressed again. Operation. Thereby, the cooking menu displayed on the menu display part 93 switches from blinking to lighting, and the setting of the cooking menu is completed. Here, each time the first switching button 88 is pressed, the cooking menu advances one by one, and each time the second switching button 89 is pressed, the cooking menu returns one by one. However, this is also used when setting another heat retention temperature or discharge amount. It is done.

  Further, when the heat insulation temperature button 86 is pushed, the temperature display section 92 blinks to indicate that the input of the heat insulation temperature can be changed. Next, the first switching button 88 or the second switching button 89 is pushed to change the heat insulation temperature displayed on the temperature display unit 92 in order, and when the desired heat insulation temperature is displayed, the heat insulation temperature button 86 is pressed again. Push the operation. Thereby, the heat insulation temperature displayed on the temperature display part 92 switches from blinking to lighting, and the setting of the heat insulation temperature is completed. Here, each time the first switching button 88 is pressed, the number of the heat retention temperature displayed on the temperature display unit 92 increases by 1 ° C., and every time the second switching button 89 is pressed, the number of the heat retention temperature decreases by 1 ° C. Thus, the heat retention temperature can be set in units of 1 ° C. within a range of 70 ° C. to 90 ° C., for example.

  Similarly, when the discharge amount button 85 is pushed, the discharge amount display unit 91 blinks to indicate that the input of the heat retention temperature can be changed. Next, the first switching button 88 or the second switching button 89 is pushed to change the soup discharge amount displayed on the discharge amount display unit 91 in order, and when the desired discharge is displayed, the discharge amount button 85. Press again. Thereby, the discharge amount of soup displayed on the discharge amount display part 91 is switched from blinking to lighting, and the setting of the discharge amount is completed. Here, each time the first switch button 88 is pressed, the discharge amount number displayed on the discharge amount display section 91 increases by 10 ml, and every time the second switch button 89 is pressed, the discharge amount number decreases by 10 ml. For example, the discharge amount can be set in units of 10 ml in the range of 100 ml to 250 ml. Further, the discharge amount of the soup can be changed and set at the time of discharge.

  As the control means 51, a heating cooking process and a heat retention process are performed similarly to 1st Example except determining the difference in a cooking menu as a difference in the viscosity of a to-be-cooked thing (soup). For example, when “consomme soup” is set as the cooking menu, the control unit 51 determines that the viscosity of the food to be cooked is low, and when “potage soup” is set as the cooking menu, Judge that the viscosity is high. And the heat retention control means 82 lengthens the drive time of the pump 11 and lowers the viscosity of the soup as the viscosity of the soup corresponding to the set cooking menu increases when discharging the food to be cooked during the heat retention process. Indeed, by shortening the driving time of the pump 11, the supply amount of soup finally discharged from the discharge port 29 is made constant regardless of the viscosity.

  Further, even if the cooking menu is the same, the viscosity of the soup may change depending on the temperature. Therefore, when the cooking menu corresponding to the viscosity of the soup is set, the detection of the container 4 detected by the temperature detection means 41 is detected. It is preferable that, for example, the heat retaining control unit 82 of the control unit 51 controls the operation time of the pump 11 so that a predetermined amount of the cooking object is discharged from the discharge port 29 according to the temperature. Specifically, for a cooking menu in which the viscosity of a specific soup changes, the lower the temperature detected by the temperature detection means 41, the longer the operation time of the pump 11, and vice versa. The operation time of the pump 11 is shortened, so that the detection temperature of the container 4 detected by (1) is high. The discharge amount from the discharge port 29 can be varied depending on the length of the operation time of the pump 11.

  During the warming process, by pushing and operating the discharge button 59, the food to be cooked can be easily discharged from the discharge port 29 with the discharge amount displayed on the discharge amount display unit 91 regardless of the set cooking menu. Can do. Further, for example, when the cup receiving this is small with respect to the set discharge amount, and there is a possibility that the food to be cooked overflows from the cup as it is, the operation / stop button 58 is manually pushed. The heat retaining control means 82 accepts an operation signal from the operation / stop button 58, interrupts the operation of the pump 11, and immediately stops the discharge of the food to be cooked. To be cooked can be poured.

  As described above, in this embodiment, the container 4, the pump 11 as the discharge means for discharging the cooking object in the container 4 to the outside, the heating coil 7 as the heating means for heating the container 4, and the heating coil 7. And a control means 51 for controlling the operation of the pump 11, and a menu button 87 as a selection means for selecting the type of food to be cooked. The control means 51 includes a menu button 87 selected by the menu button 87. An operation / stop button 58 as an operation means for controlling the operation of the heating coil 7 and the pump 11 according to the type of the cooked product and forcibly stopping the discharge of the cooked product during the discharge of the cooked product. Provided.

  In this case, by simply selecting the type of food to be cooked by the menu button 87, appropriate heating and heat insulation control suitable for the type and discharge control can be automatically performed, and the type of food to be cooked is related. The predetermined amount of food to be cooked can be easily discharged. In addition, when something abnormal occurs during the discharge of the cooking object, for example, when the cup to be received is small with respect to the set discharge amount, the cooking object is immediately operated by operating the operation / stop button 58 manually. Can be stopped.

  In addition, this invention is not limited to the said Example, It can change in the range which does not deviate from the meaning of this invention. For example, the discharge operation of the food to be cooked by the discharge means is not limited to the heat retention process.
