[0009] Hereinafter, preferred embodiments of the cooking device according to the present invention will be described with reference to the accompanying drawings. In addition, common parts are designated by common reference numerals throughout the drawings.

[0010] 1 to 3 show a rice cooker 100 as one embodiment of the cooking device of the present invention. Based on these drawings, the overall configuration of the rice cooker 100 in this embodiment will be described. 1 is a main body, which is generally rectangular with a front surface, a rear surface, a left side surface, and a right side surface facing each other when viewed from above, and has an open top surface. 2 is a lid body that can be opened and closed to cover the top opening of the main body 1, and like the main body 1, is generally rectangular with a front surface, a rear surface, a left side surface, and a right side surface facing each other when viewed from above, and the cross section of the top surface is generally mountain-shaped with a gently sloping surface. The main body 1 has a pot accommodating section 3 with an open top surface, and when the lid body 2 is opened, a bottomed pot 4 as a container for accommodating water and rice to be cooked is detachably accommodated in the pot accommodating section 3. The pot accommodating section 3 is configured by combining a bowl-shaped resin inner frame 5 and the like, and the whole is formed into a bottomed cylindrical shape.

[0011] Pot 4 has a main material 7 made of aluminum with good thermal conductivity, and a heating element 8 made of a magnetic metal plate such as ferritic stainless steel joined to the outer surface of main material 7 from the lower side to the bottom. In addition, a heating coil 11 is provided on the outer surface of inner frame 5, which faces the lower side of pot 4 to the bottom, as a heating means for electromagnetic induction heating of heating element 8 of pot 4. When high-frequency current is supplied to heating coil 11, heating element 8 of pot 4 is heated by the alternating magnetic field generated by heating coil 11, and the food to be cooked in pot 4 is heated during cooking and keeping warm. In addition, a pot sensor 12 as a pot temperature detection means is disposed in the center of the bottom of inner frame 5 so as to come into elastic contact with the outer bottom of pot 4.

[0012] The top surface of the lid 2 is provided with a steam vent 15 that exhausts steam generated from the food being cooked in the pot 4 to the outside of the rice cooker 100. A lid operating body 14 serving as a lid opening means is disposed in an exposed state on the front upper surface of the lid 2. When the lid operating body 14 is pushed, the engagement between the main body 1 and the lid 2 is released, and the lid 2 is opened by the hinge spring 13b of the hinge portion 13 provided on the upper rear of the main body 1, with the hinge shaft 13a provided on the rear lower part of the lid 2 as the rotation center.

[0013] In addition to the steam vent 15 and the lid operation body 14, a display operation unit 21 is provided on the top surface of the lid body 2. The display operation unit 21 is mainly composed of a display means 22 consisting of, for example, an LCD (Liquid Crystal Display) for displaying various information related to rice cooking, an operation means 23 consisting of, for example, a touch sensor for starting rice cooking and selecting a rice cooking course (see FIG. 2(A)), and a control PC (Printed Circuit) board 24 equipped with a control IC (not shown) for controlling the display means 22, operation means 23, and each part of the display operation unit 21. An operation panel 25 for protecting the display means 22, operation means 23, and control PC board 24 is disposed above the display operation unit 21. This operation panel 25 is positioned at an incline forward along one of the inclined surfaces of the lid body 2, which has a mountain-shaped cross section, making the display means 22 via the operation panel 25 easy to see from the front of the rice cooker 100 and also making the operation means 23 arranged on the operation panel 25 easy to operate from the front of the rice cooker 100.

[0014] The lid body 2 is composed of an outer lid 9, which is an exterior component, and an outer lid cover 10 that forms the lower part of the outer lid 9. Gaps and ventilation holes (not shown) are provided between the outer lid 9 and the outer lid cover 10, and the inside of the lid body 2 communicates with the outside via these gaps and ventilation holes. Note that, in order to prevent steam exhausted from the steam vent 15 from being taken into the lid body 2, it is preferable that these gaps and ventilation holes are not provided in the vicinity of the steam vent 15.

[0015] The outer lid cover 10 is provided with a metal heat sink 27 made of stainless steel or aluminum with anodized aluminum. An inner lid 28 made of metal made of stainless steel or aluminum with anodized aluminum is provided on the outside of the heat sink 27. An inner lid assembly 26 is disposed under the lid 2 as a lower member of the lid 2. The inner lid assembly 26 is made of a metal material having a disk shape with approximately the same diameter as the upper opening of the pot 4, and includes an inner lid 28 that covers the upper opening of the pot 4, a lid packing 29 as an elastic member provided around the entire outer circumference of the inner lid 28 to seal between the inner lid 28 and the pot 4, and a pressure adjusting part 30 that adjusts the internal pressure of the pot 4. The annular lid packing 29 abuts against the upper surface of the pot 4, which is the opening, when the lid 2 is closed as shown in FIG. 1, to close the gap between the pot 4 and the inner lid 28 and seal the steam generated from the pot 4.

[0016] Inside lid 2, there are provided a lid heater 31 as a lid heating means for heating inner lid 28, and a thermistor-type lid temperature sensor 32 for controlling the temperature of inner lid 28 by lid heater 31. Inside lid 2, there is formed a steam exhaust path 33 that connects steam port 15 and pressure adjustment part 30 as a passage for releasing steam generated in pot 4 to the outside.

[0017] The pressure adjusting unit 30 is provided with a pressure adjusting valve 34 that opens and closes a steam exhaust path 33 between the inside of the pot 4 and the steam port 15. The pressure adjusting valve 34 is ball-shaped and works in conjunction with a solenoid 35 provided inside the lid 2. The solenoid 35 rotates the pressure adjusting valve 34 so that when steam in the pot 4 is to be released to the outside, the steam exhaust path 33 is opened, and when the inside of the pot 4 is to be pressurized or depressurized, the steam exhaust path 33 is closed. When pressurizing, the food to be cooked in the pot 4 is heated by high-frequency current flowing through the heating coil 11, the food boils and generates steam, and when the internal pressure of the pot 4 reaches a predetermined value due to the steam filling the pot 4, the steam exhaust path 33 is opened against the weight of the pressure adjusting valve 34, thereby maintaining the pressure in the pot 4 at or above atmospheric pressure.

[0018] Reference numeral 38 denotes a pressure reducing means for lowering the pressure inside pot 4 below normal atmospheric pressure with lid 2 closed on main body 1. After pot 4 is accommodated in pot accommodating body 3 and lid 2 is closed, pressure reducing means 38 operates pressure reducing pump 39, which serves as the operating source of pressure reducing means 38, in a state in which pressure regulating valve 34 blocks steam exhaust path 33 by energizing solenoid 35 to reduce the internal pressure of sealed pot 4. When the pressure inside pot 4 drops below atmospheric pressure by a certain value, pressure reducing pump 39 stops operating while steam exhaust path 33 remains blocked, maintaining the inside of pot 4 in a reduced pressure state. When the pressure inside pot 4 is to be returned from the reduced pressure state to the same pressure as the outside air, solenoid 35 rotates pressure regulating valve 34 to stop operating pressure reducing pump 39 and open steam exhaust path 33.

[0019] Reference numeral 42 denotes a unitized heating board assembly that is disposed inside the main body 1 and includes a heating control means 43. The heating control means 43 is configured to include a microcomputer (microcomputer) equipped with a control IC such as a CPU, a readable and writable memory that stores various information and data, a timer that can measure the time related to cooking, and the like, in order to electrically control each part of the rice cooker 100 in combination with the display operation unit 21, and electrically controls each part of the rice cooker 100. Specifically, the heating board assembly 42 is connected to the display operation unit 21, and the heating control means 43 receives each temperature detection signal from the pan sensor 12 and the lid temperature sensor 32, outputs a heating control signal to the heating coil 11 and the lid heater 31, respectively, and outputs a drive control signal to the solenoid 35 that operates the pressure adjusting valve 34 and the pressure reducing means 38, respectively.

[0020] 2(A) is a perspective view of the main part of the cover body 2 with the operation panel 25 removed, and FIG. 2(B) is a perspective view of the main part of the cover body 2 with the operation panel 25 and the display operation unit 21 removed. FIG. 3 is a cross-sectional view of FIG. 2(A) along CC with the operation panel 25 attached. With reference to FIG. 2 and FIG. 3, the operation means 23 of this embodiment is a capacitive coil spring switch, which generates capacitance when the user's finger approaches the position of each button on the operation panel, and outputs an ON / OFF signal when this capacitance is detected by a capacitance sensor mounted on the control PC board via a coil spring. Note that this is just one example, and a mechanical switch pressed by the operation means 23 may also be used.

[0021] A display board housing section 51 capable of housing the display operation unit 21 is provided at the front of the upper surface of the outer lid 9. The display board housing section 51 of this embodiment is formed in a substantially rectangular parallelepiped shape with the upper surface of the outer lid 9 recessed downward, and as shown in Fig. 2(A) , the opening and bottom section 51a of the display board housing section 51 are formed in substantially the same shape as the control PC board 24, so that the display operation unit 21 can be positioned simply by housing it in the display board housing section 51.

[0022] 2(B), the display board housing 51 is provided with a protruding portion 52 on the bottom 51a that protrudes toward the inside of the display board housing 51, and this protruding portion 52 is configured so as not to come into contact with the lower surface of the control PC board 24 or the components and wiring mounted on the control PC board 24 when the display operation unit 21 is housed in the display board housing 51. The display board housing 51 is also provided with board frame support portions 53, 53... that support the edge of the control PC board 24 on the side wall 51b, so that when the display operation unit 21 is housed in the display board housing 51, the components and wiring mounted on the lower surface of the control PC board 24 do not come into contact with the bottom 51a, and the upper surface of the display means 22 mounted on the control PC board 24 and the capacitive coil spring switch of the operation means 23 are configured so as to be flush with the upper edge of the display board housing 51, i.e., the upper surface of the inclined outer lid 9. Therefore, when the operation panel 25 is disposed on the upper surface of the outer lid 9, the display operation unit 21 is sandwiched between the lower surface of the operation panel 25 and the substrate frame support parts 53, 53... of the display substrate housing part 51, so that the display operation unit 21 can be held in a predetermined position even when the lid body 2 is opened or closed. As shown in Fig. 2(B) , the protruding part 52 has a shape combining a semicircle and a rectangle in a top view, but is provided at an angle to the side wall 51b in a top view, and is formed along the direction F in which the desiccant 55 described later is inserted, so that the protruding part 52 does not get in the way when the desiccant 55 is housed in the recess 56a of the desiccant housing part 56. As shown in FIG. 3, bottom 51a is formed so as to be approximately parallel to the upper surface of inclined outer lid 9, i.e., approximately parallel to operation panel 25, and is configured to facilitate accommodating desiccant 55 in recess 56a of desiccant accommodating section 56 provided on the lid body operating body 14 side of bottom 51a, i.e., the lower side of inclined bottom 51a, and on the opposite side from protrusion 52.

[0023] The display board housing section 51 is provided in the side wall 51b with a wiring hole 54 through which the wiring connecting the display operation unit 21 and the heating board assembly 42 passes, and ventilation holes 50, 50 capable of sucking in and exhausting the gas in the display board housing section 51. Here, it is preferable that the wiring hole 54 is not blocked even after the wiring is laid, and the wiring hole 54 capable of sucking in and exhausting the gas in the display board housing section 51 can also function as the ventilation holes 50, 50. In this case, it is preferable that the wiring hole 54 and the ventilation holes 50, 50 are provided on the opposing side walls 51b, so that the gas in the display board housing section 51 can be ventilated quickly. In addition, as shown in FIG. 2(A), it is preferable that the wiring hole 54 and the ventilation holes 50, 50 are arranged so as to be above the control PC board 24 of the housed display operation unit 21, so that the heat released from the display operation unit 21 during ventilation can also be exhausted to the outside of the display board housing section 51.

[0024] Reference numeral 55 denotes a desiccant that adsorbs moisture in the display substrate housing 51, and 56 denotes a desiccant housing that can house the desiccant 55. The desiccant of this embodiment is a type in which bead-shaped desiccant is enclosed in a bag, and has a main body 55a and a bonding portion 55b formed around the main body 55a by bonding the fabric of the bag together. The desiccant housing 56 is formed in a substantially rectangular parallelepiped shape with the bottom 51a of the display substrate housing 51 recessed downward, and has a recess 56a that houses the desiccant 55, and a lock rib 56b formed to protrude horizontally from the vicinity of the upper edge of the side wall 62 of the recess. 2(A), conventionally, a cutout portion N is provided by cutting out a part of the control PC board 24, and the desiccant 55 is folded in half or in four and stored in this cutout portion N, but with this configuration, the desiccant 55 can be disposed simply by storing it in the desiccant storage portion 56 without folding it, which saves the labor during assembly. Also, since there is no need to provide the cutout portion N in the control PC board 24, the design flexibility of the control PC board 24 is expanded, and the entire surface of the control PC board 24 can be effectively utilized.

[0025] As shown in Fig. 2(B), the opening and bottom surface 61 of the recess 56a are formed in substantially the same shape as the top view of the desiccant 55 in a normal unfolded state, and as shown in Fig. 3, the depth of the recess 56a, i.e., the height of the side wall 62 of the recess 56a, is formed slightly higher than the thickness of the main body 55a of the desiccant 55 in a normal unfolded state, so that the desiccant 55 can be positioned simply by being accommodated in the recess 56a without being folded. As described above, the recess 56a is provided on the lid operating body 14 side of the bottom 51a of the display board accommodation section 51, i.e., on the lower side of the inclined bottom 51a and on the opposite side to the protruding portion 52, and the bottom surface 61 of the recess 56a is formed substantially parallel to the inclined bottom 51a, i.e., inclined toward the lid operating body 14 side, making it easy to accommodate the desiccant 55 in the recess 56a from the direction of the arrow F. The upper edge of the recess 56a is rounded, so that when the desiccant 55 is accommodated in the recess 56a, the upper edge slides to make it easier to accommodate the desiccant 55 in the recess 56a. The bottom surface 61 of the recess 56a may be roughened, for example, like a file, to increase friction and suppress misalignment of the desiccant 55 once it has been accommodated and positioned. Conversely, the bottom surface 61 of the recess 56a may be smoothed, so that when the desiccant 55 is accommodated in the recess 56a, it is easier to slide on the bottom surface 61 and place it in a predetermined position. A hook portion protruding horizontally or a hook portion bent downward may be provided on the side wall 62 of the recess 56a, so that the bonded portion 55b of the accommodated desiccant 55 is positioned under the hook portion. For example, even when the lid 2 is opened and the recess 56a becomes vertical, the bonded portion 55b hits the hook portion to suppress the desiccant 55 from coming out of the recess 56a. In this case, the hook portion is preferably provided on the side wall 62 located below the recess 56a when the recess 56a is vertical, that is, on the side wall 62 on the hinge portion 13 side of the recess 56a.

[0026] The lock rib 56b presses the contained desiccant 55 toward a bottom surface 61 as the bottom of the recess 56a, and is made of resin in an elongated shape similar to the outer lid 9, and is flexible. As shown in Fig. 3, the lock rib 56b is provided on the side wall 62 of the recess 56a at a height substantially equal to the thickness of the main body 55a of the desiccant 55 in a normal state, and is formed so as to extend from the side wall 62 on the lid operating body 14 side toward the hinge part 13 side substantially parallel to the bottom surface 61. With this configuration, when the desiccant 55 is contained in the recess 56a, the lock rib 56b abuts against the main body 55a of the desiccant 55 and presses it toward the bottom surface 61, so that the desiccant 55 can be sandwiched and held between the lock rib 56b and the bottom surface 61. Even if the position of the desiccant 55 in the recess 56a moves toward the hinge portion 13, for example, when the lid 2 is opened and the recess 56a becomes vertical, the desiccant 55 can be pressed toward the bottom surface 61 as long as the lock rib 56b is in contact with the main body 55a of the desiccant 55. Therefore, the lock rib 56b and the bottom surface 61 function as a desiccant clamping portion that clamps the desiccant 55. The lock rib 56b is provided on the side wall 62 side of the lid operation body 14 side in the recess 56a of the desiccant storage portion 56, that is, on the side wall 62 side below the inclined bottom portion 51a, and the desiccant 55, to which the downward force of gravity acts along the bottom surface 61 of the recess 56a, is clamped between the lock rib 56b and the bottom surface 61 and stably held, thereby suppressing the positional displacement of the desiccant 55.

[0027] The lock rib 56b has a generally semicircular tip and is disposed offset from the center of the lower sidewall 62 in top view toward the outside of the lid 2 away from the center of the bottom surface 61, leaving more space toward the center of the bottom surface 61 at the opening of the recess 56a, making it easier to accommodate the desiccant 55 that is moved from the center of the bottom surface 61 in the direction of arrow F and accommodated in the recess 56a, and also preventing the desiccant 55 from interfering with the tip of the lock rib 56b when being accommodated. The lock rib 56b is preferably positioned at a position where the main body 55a can be stably pressed toward the bottom surface 61 when the desiccant 55 is accommodated.

[0028] Next, the operation of the rice cooker 100 having the above-mentioned configuration will be described. First, the operation of assembling the rice cooker 100 will be described. Before the display operation unit 21 as shown in FIG. 2B is placed in the display board housing 51, the desiccant 55 is accommodated in the recess 56a by sliding it in the direction of the arrow F with the bottom 51a. Here, the protruding portion 52 is inclined with respect to the side wall 51b in a top view, so that the protruding portion 52 is prevented from interfering with the desiccant 55 when the desiccant 55 is accommodated. In addition, the bottom 51a is inclined toward the recess 56a, the opening and bottom surface 61 of the recess 56a have approximately the same area as the desiccant 55, the upper edge of the recess 56a and the tip of the lock rib 56b are rounded, and the lock rib 56b is arranged offset from the center of the lower side wall 62 toward the outside of the lid body 2, so that the desiccant 55 can be smoothly accommodated in the recess 56a without being bent.

[0029] When the desiccant 55 is placed in the recess 56a, the bottom surface 61 has approximately the same area as the desiccant 55, so that the desiccant 55 is positioned in the recess 56a. The lock rib 56b comes into contact with the main body 55a of the desiccant 55 and presses the main body 55a toward the bottom surface 61, thereby sandwiching and holding the desiccant 55 between the lock rib 56b and the bottom surface 61.

[0030] 2B, the display operation unit 21 is placed in the display board housing 51, and the other components in the lid 2 are placed, and then the operation panel 25 is attached to the upper surface of the outer lid 9, so that the display operation unit 21 is sandwiched between the lower surface of the operation panel 25 and the board frame support parts 53, 53, . . . of the display board housing 51. Therefore, even if the lid 2 is opened and the desiccant housing 56 is in a vertical state, for example, if the desiccant 55 is misaligned in the recess 56a, this will not occur. Even if the desiccant 55 is misaligned, since the control PC board 24 is located above the desiccant housing 56, even if the desiccant 55 moves from the recess 56a to the hinge part 13 side, the bonding part 55b of the desiccant 55 interferes with the control PC board 24, so that the desiccant 55 can be prevented from jumping out of the recess 56a. The desiccant 55 arranged in this manner absorbs moisture within the display substrate accommodating section 51, thereby keeping the display substrate accommodating section 51 dry and preventing the moisture within the display substrate accommodating section 51 from adhering to the display means 22 of the display operation unit 21 and causing it to cloud over.

[0031] Next, the operation of the rice cooker 100 during operation, such as when cooking rice, will be described. The temperature of the food to be cooked in the pot 4 rises, and in particular when steam is generated from the food to be cooked and adheres to the inner lid 28, or when the lid heater 31 is driven, the temperature of the inner lid 28 rises. Here, the steam from the food to be cooked passes through the steam exhaust path 33 and is exhausted to the outside of the rice cooker 100 from the steam vent 15, but the temperature inside the lid body 2 rises, and the temperatures of the parts inside the lid body 2, such as the inner lid assembly 26, the outer lid 9, and the outer lid cover 10, also rise. At this time, inside the lid body 2, warm air with a higher temperature is exhausted to the outside from the gap between the outer lid 9 and the outer lid cover 10 and the ventilation holes, and air circulation occurs in which cold air enters from the outside.

[0032] When the temperature of the outer lid 9 rises, the temperature inside the housing portion 51 for display substrate formed in the outer lid 9 and the temperature inside the desiccant housing portion 56 also rise. In particular, the desiccant 55 pressed against the bottom surface 61 of the desiccant housing portion 56 of the outer lid 9 receives heat directly from the outer lid 9, and its temperature rises to the same extent as that of the outer lid 9. Here, the desiccant 55 is more likely to adsorb moisture at a higher temperature, so that the inside of the housing portion 51 for display substrate can be kept drier and the moisture inside the housing portion 51 for display substrate can be more effectively prevented from fogging up the display means 22.

[0033] Furthermore, when the temperature of the outer lid 9 rises to a higher temperature, for example, about 60°C, the desiccant 55 begins to release the moisture that it had adsorbed. At this time, the temperature inside the display board housing 51 also rises, so air circulation occurs through the wiring hole 54 and the ventilation holes 50, 50 that communicate with the space between the outer lid 9 and the outer lid cover 10, and the moisture released from the desiccant 55 is discharged from the wiring hole 54 and the ventilation holes 50, 50 together with the warm air inside the display board housing 51, and cold air enters from the space through the wiring hole 54 and the ventilation holes 50, 50. The discharged warm air and moisture are then discharged to the outside of the rice cooker 100 by the circulation of air inside the lid body 2 as described above. In this way, the desiccant 55 absorbs moisture inside the display board housing 51, and even if moisture is released from the desiccant 55, it is discharged to the outside of the display board housing 51, so that the inside of the display board housing 51 can be kept dry and the moisture inside the display board housing 51 can be prevented from fogging up the display means 22.

[0034] As described above, the rice cooker 100 as a heating cooker of this embodiment comprises a display means 22 capable of displaying information related to cooking, and a display board accommodation section 51 as a display means accommodation section capable of accommodating a display operation unit 21 having the display means 22, and a desiccant accommodation section 56 for accommodating a desiccant 55 that adsorbs moisture in the display board accommodation section 51 is provided at the bottom 51a of the display board accommodation section 51, and the desiccant accommodation section 56 is configured to have a lock rib 56b as a desiccant clamping section that clamps the desiccant 55, and a bottom surface 61 of the desiccant accommodation section 56.

[0035] With this configuration, the desiccant 55 is sandwiched between the lock rib 56b and the bottom surface 61 of the desiccant accommodating section 56, so that the desiccant 55 can be easily placed in a predetermined position within the desiccant accommodating section 56 when assembling the rice cooker 100, thereby reducing the effort required for assembly.

[0036] Moreover, the desiccant clamping portion of this embodiment is composed of a bottom surface 61 as the bottom of the desiccant accommodating portion 56 against which the desiccant 55 abuts, and a lock rib 56b as a rib-shaped desiccant holding portion that holds the desiccant 55 by pressing it toward the bottom surface 61. This simple configuration allows the desiccant 55 to be clamped and the desiccant 55 to be easily positioned within the desiccant accommodating portion 56.

[0037] The rice cooker 100 of this embodiment includes a main body 1 having a pot 4 for accommodating food to be cooked as the food to be cooked, and a lid 2 for covering an opening on the top surface of the main body 1, and a display board housing 51 is provided on the lid 2. Therefore, when the rice cooker 100 is in operation, when the temperature of the food to be cooked in the pot 4 of the main body 1 rises, the temperature inside the lid 2 rises, and the desiccant 55 pressed against the bottom surface 61 of the desiccant housing 56 receives heat directly from the outer lid 9 of the lid 2 and rises in temperature to the same extent as the outer lid 9. This raises the temperature of the desiccant 55 to the same extent as the outer lid 9, thereby keeping the inside of the display board housing 51 drier and further suppressing the moisture in the display board housing 51 from clouding the display means 22.

[0038] In this embodiment, bottom 51a of housing 51 for display substrate is inclined, and lock rib 56b is provided below the inclination of bottom 51a of housing 51 for display substrate in desiccant housing section 56. Therefore, desiccant 55 can be smoothly accommodated in recess 56a by sliding it in the direction of arrow F from the center of bottom 51a.

[0039] The present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, in the present embodiment, the rice cooker 100 is described as an example, but other cooking appliances such as a pressure cooker may be used. In addition, the numerical values ​​exemplified in the embodiment are merely examples, and may be appropriately modified according to the specifications of the cooking appliance.
