FIG. 2 is an external perspective view of the cooking device with the bottle of the present embodiment removed. In addition, although the cooking device of this Embodiment is a structure which can set a multiple types of bottle, in FIG.1 and FIG.2, it illustrates and demonstrates the bottle for pressure reduction. In the following description, a mixer is illustrated as an example of a cooking device. For example, the technology of the present disclosure can be applied to various uses such as a food processor, a slicer, and a sake brewer.

  As shown in FIG. 1, the cooking device 1 has an inside of a decompression bottle (container) 70 in which ingredients (which can include food to be cooked, ingredients before cooking, during cooking, and after cooking) are charged. After decompression, the processing member 74 (see FIG. 3) is used to finely process the food to a predetermined particle size. A mounting table for the decompression bottle 70 is a cooker body 10, and a processing motor 41 and a control circuit 53 (see FIG. 3) are accommodated in the case of the cooker body 10. The front surface of the case of the cooker body 10 protrudes forward in a mountain shape, and an operation panel 11 is provided on the slope of the front surface of the case. The operation panel 11 is provided with indicator lamps for operation modes and errors, and various switches used for mode change and manual operation.

  A semi-cylindrical side pole 20 is erected next to the cooker body 10, and a vacuum pump (decompression unit, decompression pump) 42 (see FIG. 3) for pressure reduction and piping are installed in the case of the side pole 20. , Wiring and the like are accommodated. An illumination bar (display unit) 21 is provided in front of the side pole 20, and the reduced pressure state of the decompression bottle 70 is displayed stepwise by the illumination bar 21. An arm 30 connected to the bottle cap 72 of the decompression bottle 70 is supported on the upper side of the side pole 20 so as to be swingable in the vertical direction. On the distal end side of the arm 30, a contact head 31 having a circular shape when viewed from above is formed in airtight contact with the upper surface of the bottle cap 72.

  When the decompression bottle 70 is set in the cooking device body 10, the processing member 74 provided on the bottle base 73 is connected to the motor 41 of the cooking device body 10. Although not shown in detail, the coupling provided on the rotating shaft of the machining member 74 and the coupling provided on the output shaft of the motor 41 are engaged and mechanically connected. When the arm 30 is connected to the bottle cap 72 of the decompression bottle 70, the decompression bottle 70 is connected to the vacuum pump 42 through the intake passage (decompression unit, intake system) 49 in the case of the arm 30 and the side pole 20. . Thus, in the cooking device 1, a processing mechanism is configured by the motor 41, the processing member 74, and the power transmission mechanism. The vacuum pump 42 and the intake passage 49 constitute a “decompression unit” that depressurizes the decompression bottle 70.

  As shown in FIG. 2, the cooking device 1 makes the decompression bottle 70 detachable with respect to the cooking device body 10 by lifting the arm 30 directly above. A concave portion 23 that is recessed along the outer shape of the arm 30 is formed on the side surface 22 of the semi-cylindrical side pole 20 on the cooker body 10 side. For this reason, when the arm 30 is lowered directly, the entire arm 30 is completely accommodated in the recess 23, and the arm 30 does not become an obstacle when the bottle is replaced. The lower part 24 of the recess 23 is cut out in an arc shape so as to leave a gap in a state where the arm 30 is accommodated, and the arm 30 can be pulled up from the recess 23 by placing a finger in the gap.

  An annular pad 32 is provided on the contact head 31 of the arm 30, and the annular pad 32 comes into airtight contact with the upper portion of the bottle cap 72 when the arm 30 is tilted horizontally. An inlet of the intake passage is opened inside the annular pad 32, and an outlet of the exhaust passage of the decompression bottle 70 is formed on the upper surface of the bottle cap 72. The exhaust path of the bottle cap 72 and the intake path of the arm 30 communicate with each other in an airtight manner by the annular pad 32, and air is drawn into the vacuum pump 42 in the side pole 20 from the decompression bottle 70. In the middle of the extending direction of the arm 30, a slit 33 is formed that escapes from the peripheral wall 75 of the bottle cap 72 when the arm 30 is tilted horizontally.

  On the upper surface of the cooker main body 10, a rectangular annular convex portion 12 that projects the bottom opening of the bottle base 73 of the decompression bottle 70 from the inside is projected. The annular protrusion 12 is formed along the opening edge of the bottle base 73, and the arcuate portions at the four corners of the annular protrusion 12 are raised so that the bottle base 73 can be easily guided. One side of the annular convex portion 12 is cut out, and a socket 13 for supplying electric power to the heating bottle 80 (see FIG. 4) is provided in the cutout portion. An opening 14 for coupling is formed inside the annular convex portion 12, and the output shaft of the motor 41 is connected to the processing member 74 by positioning the bottle base 73 on the annular convex portion 12.

  In addition to the decompression bottle (container) 70, the cooking device 1 is also used in a heating bottle (container) 80 (see FIG. 4) and a storage bottle (container) 90 (see FIG. 5). When the heating bottle 80 is used, the arm 30 is accommodated in the recess 23 of the side pole 20, and the heating bottle 80 is processed while heating the food without reducing the pressure. When the storage bottle 90 is used, the arm 30 is pulled out from the recess 23 of the side pole 20, and the inside of the storage bottle 90 is decompressed to maintain the freshness of the processed food product for a long time. Thus, it can be used for various purposes by exchanging the bottle of the cooking device 1.

It is installed (see FIG. 4).

  The detection results of the first detection unit 43 to the third detection unit 45 are output to a determination circuit (not shown), and the type of the bottle is determined by the determination circuit based on a combination of these detection results. In this way, a discrimination unit that discriminates the type of the bottle is configured by the detection results and the discrimination circuit of the first detection unit 43 to the third detection unit 45. In the cooking device 1, the function can be limited according to the type of the bottle by determining the type of the bottle. Depending on the type of the bottle, the heat treatment or the decompression process is prohibited, and for example, it is possible to prevent the cooking by mistake for the non-heating decompression bottle 70.

  A capacitance sensor 47 for detecting foreign matter is installed in the contact head 31 of the arm 30, and foreign matter such as water and food in the contact head 31 is detected from the change in capacitance. When an abnormality is detected by the capacitance sensor 47, the driving of the vacuum pump 42 is stopped. A pressure sensor (atmospheric pressure measurement unit) 51 for detecting the pressure in the bottle is installed in the middle of the intake passage 49 in the side pole 20 to detect foreign matter such as water and food in the intake passage 49 from the change in pressure. Is done. When an abnormality is detected by the pressure sensor 51, the driving of the vacuum pump 42 is stopped. Further, an air release valve 52 is installed in the middle of the intake passage 49, and the intake passage 49 is returned to atmospheric pressure by opening the air release valve 52.

  The intake passage 49 connects the vacuum pump 42 and the decompression bottle 70 in a communication state (a decompression state by the vacuum pump 42) or an atmosphere release state by the atmosphere release valve 52. A pressure sensor (atmospheric pressure measuring unit) 51 provided in the intake passage 49 measures the pressure in the decompression bottle 70 when the intake passage 49 is in a communication state (a decompression state by the vacuum pump 42), and the intake passage 49 is in the atmosphere. When the open valve 52 is open to the atmosphere, the atmospheric pressure (atmospheric pressure at the place where the cooking device 1 is installed or used) is measured. As described above, the pressure and the atmospheric pressure in the decompression bottle 70 can be measured by the single pressure sensor 51 provided in the intake passage 49, thereby simplifying the structure of the cooking device 1, saving space, and reducing the cost. Can be achieved.

  As described above, the motor 41 that rotationally drives the processing member 74 is installed in the case of the cooker body 10, and a current detection circuit (not shown) that detects overcurrent is connected to the motor 41. . When the current detection circuit detects an overcurrent of the motor 41, the driving of the motor 41 is stopped.

  The decompression bottle 70 has a bottle cap 72 attached to the top of a bottle body 71 made of Tritan (registered trademark) and a bottle base 73 attached to the bottom of the bottle body 71. An exhaust path is formed in the bottle cap 72, and a check valve for preventing backflow into the bottle is provided in the middle of the exhaust path. A peripheral wall 75 is formed on the outer edge of the bottle cap 72, and the second detection unit 44 is pushed in by the peripheral wall 75 entering the slit 33 of the arm 30. A processing member 74 is rotatably supported on the bottle base 73, and a magnet 76 to be detected by the first detection unit 43 is provided.

  When the decompression bottle 70 is used, the decompression bottle 70 is installed on the cooker body 10, and the abutment head 31 of the arm 30 is abutted against the bottle cap 72. As a result, the magnet 76 of the bottle base 73 faces the first detection unit 43 of the cooker body 10, and the peripheral wall 75 of the bottle cap 72 enters the slit 33 of the arm 30. The first detection unit 43 detects the magnet 76 of the bottle base 73, and the second detection unit 44 detects the peripheral wall 75 of the bottle cap 72. When the first and second detection units 43 and 44 are turned on and the third detection unit 45 is turned off, the decompression bottle 70 is detected.

  When the operation is started, the decompression bottle 70 is decompressed by the vacuum pump 42. At this time, the decompression state of the decompression bottle 70 is displayed on the illumination bar 21 of the side pole 20. When the vacuum pump 42 is stopped and the decompression of the decompression bottle 70 is completed, the motor 41 is driven and the processing member 74 is rotated to process the food.

  As shown in FIG. 4, the heating bottle 80 has a bottle cap 82 attached to the top of a glass bottle main body 81 and a bottle base 83 attached to the bottom of the bottle main body 81. A magnet 85 to be detected by the third detection unit 45 is provided on the outer peripheral edge of the bottle cap 82.

Further, the bottom of the heating bottle 80 is formed of a heat conductive material. Inside the bottle base 83, a heater (heating unit) 87 capable of heating food in the heating bottle 80 and a temperature sensor (temperature measurement unit, temperature detection unit) 88 are provided. The temperature sensor 88 indirectly measures the temperature of the food in the heating bottle 80 by detecting the temperature of the inside of the heating bottle 80 or at least a part of the heating bottle 80. Note that the temperature sensor 88 may be configured to directly measure the temperature of the food in the heating bottle 80. Hereinafter, the temperature detected by the temperature sensor 88 may be referred to as “the internal temperature of the heating bottle 80” or “the food temperature in the heating bottle 80”.

  When the heating bottle 80 is used, the heating bottle 80 is installed on the cooker body 10 in a state where the arm 30 is accommodated in the recess 23 (see FIG. 2) of the side pole 20. Thereby, the magnet 86 of the bottle base 83 faces the first detection unit 43 of the cooker body 10, and the magnet 85 on the outer periphery of the bottle cap 82 faces the third detection unit 45 of the arm 30. The first detection unit 43 detects the magnet 86 of the bottle base 83 and the third detection unit 45 detects the magnet 85 of the bottle cap 82. The heating bottle 80 is detected when the first and third detection units 43 and 45 are turned on and the second detection unit 44 is turned off.

  When the operation is started, the inside of the heating bottle 80 is heated by the heater 87. At this time, the plug of the heater 87 is inserted into the socket 13 (see FIG. 2) on the cooker body 10, and the heater 87 is energized from the cooker body 10. Further, the heating state of the heating bottle 80 is displayed on the illumination bar 21 of the side pole 20 as in the reduced pressure state. While being heated by the heater 87, the motor 41 is driven to process the food by the processing member 84. The temperature in the heating bottle 80 is detected by the temperature sensor 88, the heating of the heater 87 is controlled based on the temperature in the heating bottle 80, and the inside of the heating bottle 80 is maintained at a predetermined temperature.

  As shown in FIG. 5, the storage bottle 90 has a bottle cap 92 mounted on the top of a resin bottle main body 91. An attachment 93 for raising the bottom is detachably attached to the bottom of the storage bottle 90. When the storage bottle 90 is used, the storage bottle 90 is installed on the cooker body 10 via the attachment 93, and the contact head 31 of the arm 30 contacts the bottle cap 92. Since the storage bottle 90 is not provided with a magnet or a peripheral wall, when the storage bottle 90 is set, all of the first detection unit 43 to the third detection unit 45 are OFF. . The storage bottle 90 is not processed or heated, and the decompression operation is performed.

  As shown in FIG. 6, the operation panel 11 is provided with operation mode lamps 61a-61g, error lamps 62a-62d, a time adjustment lamp 63, and a speed adjustment lamp 64. The operation mode lamps 61a to 61g indicate a soy milk mode, a soup mode, a paste mode, a nut mode, a smoothie mode, a frozen mode, and a manual mode from the left in the drawing. Error lamps 62a to 62d indicate a mounting error, a pressure error, an excessive food error, and a temperature error from the left in the drawing.

By turning the dial switch 66 on the operation panel 11, the operation mode lamps 61a to 61g are turned on in order and the operation mode is selected. Push switches 67a to 67c indicate a flash switch, a start switch, and a release switch from the left in the figure. The flash switch performs a stirring operation only during pressing, the start switch starts various operations by pressing, and the release switch performs vacuum release.

  The cooker 1 has a control circuit 53 that is located inside the cooker body 10 and controls the entire cooker 1. The control circuit 53 includes a processor that executes various processes, a memory, and the like. The memory is composed of one or a plurality of storage media such as a ROM (Read Only Memory) and a RAM (Random Access Memory) depending on the application. In addition to the control program for the cooker 1, the memory stores an operation program corresponding to the operation mode, various parameters, and the like. In addition, the cooking device 1 is provided with an antenna and a transmission / reception circuit so that wireless communication with the tablet terminal is possible.

  FIG. 7 is a functional block diagram showing the internal configuration of the control circuit 53. The control circuit 53 includes a heating control unit 53X and a display control unit 53Y.

  The heating control unit 53 </ b> X corrects the heating control value of the cooking object by the heater 87 according to the atmospheric pressure measured by the pressure sensor 51. For example, the heating control unit 53X corrects the boiling point of water (liquid), which is a cooking object, according to the atmospheric pressure measured by the pressure sensor 51.

  FIG. 8 is data showing an example of a correspondence relationship between altitude (m), atmospheric pressure (hPa), air temperature (° C.), boiling point (° C.), and oxygen concentration (%). The heating control unit 53X is configured to be able to hold or refer to the data shown in FIG. As shown in FIG. 8, as the altitude increases (lowers), the atmospheric pressure, the temperature, the boiling point, and the oxygen concentration tend to decrease (higher). In particular, paying attention to the relationship between atmospheric pressure and the boiling point of water, the boiling point of water is 100 ° C. when the atmospheric pressure is 1002 to 1013 hPa, the boiling point of water is 99 ° C. when the atmospheric pressure is 968 to 990 hPa, and the water is water when the atmospheric pressure is 935 to 957 hPa. The boiling point of water is 97 ° C. when the atmospheric pressure is 903 to 924 hPa, the boiling point of water is 96 ° C. when the atmospheric pressure is 871 to 892 hPa, and the boiling point of water is 95 ° C. when the atmospheric pressure is 851 to 861 hPa. It is. That is, the boiling point of water that is the object to be cooked may fluctuate due to the influence of the external environment such as the place where the cooker 1 is installed or the place where it is used.

  The heating control unit 53X holds, for example, 100 ° C., which is the boiling point of water when the atmospheric pressure is 1002 to 1013 hPa, as a reference boiling point (reference heating control value), and the reference according to the atmospheric pressure measured by the pressure sensor 51 Correct the boiling point. For example, when the atmospheric pressure measured by the pressure sensor 51 is 968 to 990 hPa, the reference boiling point is corrected to 99 ° C. by the correction value “−1 ° C.”, and when the atmospheric pressure measured by the pressure sensor 51 is 935 to 957 hPa The reference boiling point is corrected to 98 ° C. with the correction value of “−2 ° C.”, and when the atmospheric pressure measured by the pressure sensor 51 is 903 to 924 hPa, the reference boiling point is corrected to 97 ° C. with the correction value of “−3 ° C.”. When the atmospheric pressure measured by the pressure sensor 51 is 871 to 892 hPa, the reference boiling point is corrected to 96 ° C. by the correction value “−4 ° C.”, and when the atmospheric pressure measured by the pressure sensor 51 is 851 to 861 hPa, The reference boiling point is corrected to 95 ° C. with a correction value of “−5 ° C.”.

  The boiling point (heating control value) correction process by the heating control unit 53X includes, for example, a timing at which the power of the cooking device 1 is switched from OFF to ON, a timing at which the cooking device 1 is turned on at predetermined time intervals, and the cooking device 1 Can be executed at a timing when it is determined that the heating bottle 80 is installed (the first and third detection units 43 and 45 are turned on and the second detection unit 44 is turned off).

  The heating control unit 53 </ b> X controls the heating of water by the heater 87 based on the corrected boiling point (heating control value) and the temperature of water (liquid) in the heating bottle 80 measured by the temperature sensor 88. That is, the heating control unit 53X controls the energization amount to the socket 13 that supplies power to the heater 87 so that the temperature of the water in the heating bottle 80 becomes the corrected boiling point. Thereby, in a place where the altitude is relatively low and the atmospheric pressure is high, water is heated to a relatively high optimum boiling point (for example, 100 ° C. which is the reference boiling point), while in a place where the altitude is relatively high and the atmospheric pressure is low, Water can be heated and boiled to a relatively low optimum boiling point (for example, 95 to 99 ° C., which is a corrected boiling point), and occurrence of blown-out and insufficient heating can be prevented.

  The heating control unit 53 </ b> X performs airing prevention control for preventing “airing” that causes the heating bottle 80 to be heated by the heater 87 when there is no object to be cooked in the heating bottle 80. When the temperature detected by the temperature sensor 88 becomes equal to or higher than the air temperature threshold value for a predetermined time, the heating controller 53X assumes that air air has occurred or is likely to occur. Power off). As an example, the heating control unit 53X determines that heating (socketing) is performed by the heater 87, assuming that there is a possibility of airing or occurring when the temperature detected by the temperature sensor 88 becomes 130 ° C. or more for 30 seconds or more. 13) can be stopped.

  The heating control unit 53X corrects the above-described air blowing temperature threshold according to the atmospheric pressure measured by the pressure sensor 51. For example, the heating control unit 53X holds the reference air temperature threshold, corrects the air temperature threshold to be lower as the atmospheric pressure measured by the pressure sensor 51 is lower, and the atmospheric pressure measured by the pressure sensor 51 The higher the value, the higher the air temperature threshold can be corrected.

  The heating control unit 53X stops heating by the heater 87 (energization to the socket 13) by the above-described airing prevention control, displays a warning on the illumination bar 21 and the operation panel 11, and / or omits illustration. Execute a voice alert by the selected speaker.

  The display control unit 53Y controls the display of the illumination bar 21 when the decompression bottle 70 is installed in the cooking device 1. The display control unit 53Y causes the illumination bar 21 to perform display based on the pressure in the decompression bottle 70 measured by the pressure sensor 51 in the communication state of the intake passage 49 (depressurized state by the vacuum pump 42).

  9A to 9D are diagrams illustrating an example of display control of the illumination bar 21 according to the present embodiment. As shown in FIGS. 9A to 9D, the illumination bar 21 includes a first lighting area 21A, a second lighting area 21B, a third lighting area 21C, and a first lighting area 21A that are adjacently arranged from below to above. 4 lighting regions 21D. In the stage before the pressure reduction by the vacuum pump 42, the pressure in the pressure reducing bottle 70 is atmospheric pressure or a value equivalent thereto, and the first lighting region 21A to the fourth lighting region 21D are not lit. When decompression by the vacuum pump 42 is started, the pressure in the decompression bottle 70 gradually decreases, and the first lighting region 21A to the fourth lighting region 21D are lit in order from the bottom to the top (FIG. 9A to FIG. 9). 9D). When the lighting state shown in FIG. 9D is reached, the decompression (evacuation) of the decompression bottle 70 may be completed, and a decompression completion report may be executed by a speaker (not shown).

  Thus, in this Embodiment, the heating control part 53X correct | amends the heating control value (for example, boiling point) of the cooking target by the heater 87 according to the atmospheric pressure which the pressure sensor 51 measured. Therefore, it is possible to appropriately control the heating of the cooking object without being affected by the external environment. For example, it is possible to stabilize the heating control of the heater 87 that heats the water (liquid) that is the object to be cooked, regardless of the difference in the external atmospheric pressure. In other words, it is possible to provide the cooking device 1 that can be suitably used at high altitudes and low altitudes regardless of altitudes such as installation locations and usage locations.

Further, if the technical idea can be realized in another way by the advancement of technology or another technique derived therefrom, the method may be implemented using the method. Accordingly, the claims cover all embodiments that can be included within the scope of the technical idea.

  In the above-described embodiment, the case where the heating control value corrected by the heating control unit 53X is the boiling point of water (liquid) that is a cooking object has been described as an example.
