Description

The present invention relates to a cooker such as a rice cooker.

Conventionally, as an example of a cooker, a rice cooker in which a pot is corrected to an appropriate position by an annular elastic portion provided on a lid is known (see, for example, Patent Document 1).

Since the induction heating coil of the rice cooker is a single concentric coil wound in a donut shape, even if the pot is placed slightly off the center of the rice cooker, the amount of heating of the pot There is no big difference in distribution. Therefore, even if the positioning of the pan is entrusted to the annular elastic portion that elastically deforms, it does not matter so much. On the other hand, in a rice cooker equipped with a plurality of induction heating coils, when the pot is placed off-center with respect to the rice cooker, the portion of the plurality of induction heating coils that is heated by the induction heating coil that is close to the pot is heated. The amount increases, and conversely, the amount of heating decreases at the portion heated by the induction heating coil separated from the pot, so that the distribution of the amount of heating of the pot differs. Therefore, in a rice cooker provided with a plurality of induction heating coils, high accuracy is required for positioning the pot in order to heat the pot evenly, and the conventional structure is insufficient.

The reflector 27 is arranged in contact with the lower surface of the ferrite holder 26. The reflector 27 occupies a slightly smaller area than the ferrite holder 26. That is, the peripheral edge of the reflector 27 is configured so as not to protrude from the peripheral edge of the ferrite holder 26. As a result, it is possible to prevent the lead wire or the like from coming into contact with the edge of the reflector 27 and being damaged. Further, a notch (not shown) is formed in a part of the peripheral edge of the reflector 27. A locking portion formed in the ferrite holder 26 is locked in this notch. In this locked state, the reflector 27 is positioned on the ferrite holder 26. The reflector 27 prevents the high-frequency magnetic field generated by energizing the coil 25 from adversely affecting peripheral devices.

The upper surface of the pot spacer 36 and the support convex portion 37 abuts on the lower surface of the flange portion of the pot 3 to support the pot 3 housed in the pot accommodating portion 6. In this supported state, the pan 3 is in non-contact with the protective frame 7 and the inner body 8 except for the side sensor 17 and the two inner body spacers 43 described later.

The outer peripheral surface of the first tubular portion 33 and the inner peripheral surface of the second tubular portion 34 are connected by a plurality of ribs 38 formed at intervals in the circumferential direction. Mounting recesses 39 are formed at five locations by two ribs 38 adjacent to each other in the vicinity. As shown in FIG. 6, each mounting recess 39 has a recess 40 surrounded by an upper end wall 32, a first cylinder 33, a second cylinder 34 and two ribs 38, and a first cylinder 33 and two. It is partitioned by ribs 38 and is composed of a guide portion 41 that opens to the inner diameter side and the lower side. In each mounting recess 39, guide convex portions 42 extending in the vertical direction are formed on both side surfaces formed by the ribs 38.

Each mounting recess 39 is formed at the same height above half the depth dimension of the pot accommodating portion 6. An inner body spacer 43 is attached to each mounting recess 39. The inner body spacer 43 is made of a synthetic resin material, and is composed of a mounting portion 44 and a protruding portion 45.

The mounting portion 44 is composed of a vertical wall 44a, an inclined side wall 44b extending obliquely from both side portions thereof, and an inclined upper wall 44c forming an upper portion of the vertical wall 44a and the inclined side wall 44b. A ridge 44d extending upward from the lower end is formed on the outer surface of each inclined side wall 44b.

The protruding portion 45 projects forward from a lower side than the upper end portion of the mounting portion 44 in a range of an intermediate position. The front surface of the projecting portion 45 faces or abuts on the outer peripheral surface of the pan 3 with a gap. A relief recess 45b is formed on the lower surface of the protrusion 45. The relief recess 45b is for suppressing the amount of resin used and preventing defects such as sink marks during molding.

The inner body spacer 43 is attached to the mounting recess 39 from below. The upper portion of the mounting portion 44 is press-fitted into the recessed portion 40, and the front surface 45a of the protruding portion 45 projects from the front opening of the guide portion 41. The guide protrusion 42 is located on the front side of the ridge 44d, and the movement of the inner body spacer 43 from the shoulder member 9 to the front is prevented.

As shown in FIG. 7, the inner body spacer 43 is attached to each of the five mounting recesses 39 and is held between the inner body 8 and the shoulder member 9. The inner body spacer 43 is attached to the first inner body spacer 43a which is mounted in two mounting recesses 39 and functions as the first positioning part of the present invention, and is mounted in the other three places as the second positioning part of the present invention. It comprises a functioning second inner body spacer 43b. The protrusion amount of the protrusion 45, that is, the front position is different between the first inner body spacer 43a and the second inner body spacer 43b. The position of the front surface 45a of the first inner body spacer 43a is the position of the outer peripheral surface of the first cylindrical portion 3b of the pot 3 when the center of the pot accommodating portion 6 and the center of the pan 3 accommodated therein coincide with each other. There is. The position of the front surface of the second inner body spacer 43b is slightly on the outer diameter side of the position of the front surface 45a of the first inner body spacer 43a (here, it is located on the outer diameter side of about 0.4 mm). Further, the first inner body spacer 43a is attached to a position opposite to the insertion portion 16 in which the side sensor 17 is provided, that is, a mounting recess 39 on the rear side of the rice cooker main body 1. Further, the first inner body spacer 43a is arranged on both sides of the second center line CL2. The position where the first inner body spacer 43a is arranged is preferably a line-symmetrical position centered on the second center line CL2.

As shown in FIG. 3, a hinge portion 46 is provided behind the shoulder member 9. The hinge portion 46 is composed of a hinge metal fitting 47, a hinge reinforcing plate 48, and a hinge cover 49. The hinge metal fitting 47 and the hinge reinforcing plate 48 are screwed and fixed to the body reinforcing plate 30. The hinge cover 49 is screwed and fixed to the shoulder member 9, and covers the hinge metal fitting 47 and the hinge reinforcing plate 48. A battery substrate 50 is attached to the hinge cover 49. The hinge portion 46 rotatably supports the lid body 2.

In the rice cooker having the above configuration, when the lid 2 is opened and the pot 3 is housed in the pot accommodating portion 6, the first inner body spacer 43a and the second inner body spacer 43b protrude toward the inner diameter side in the upper portion. .. The position of the front surface of the protruding portion 45 of the second inner body spacer 43b is radially outer than that of the front surface 45a of the protruding portion 45 of the first inner body spacer 43a. Therefore, although the front position of the protruding portion 45 of the first inner body spacer 43a is matched with the position of the outer peripheral surface of the pot 3 arranged at the center of the pot accommodating portion 6, the pan to the pan accommodating portion 6 The accommodation of 3 can be performed smoothly. Moreover, the first inner body spacer 43a protrudes from the rear side of the rice cooker main body 1. When the lid 2 is opened, the empty space between the lid 2 and the shoulder member 9 is narrow on the rear side and wide on the front side. Therefore, when accommodating the pot 3 in the pot accommodating portion 6, it is necessary to tilt the pot 3 slightly forward. As described above, the amount of protrusion of the second inner body spacer 43b on the front side is suppressed as compared with that of the first inner body spacer 43a on the rear side. Therefore, the storage work of the pot 3 can be performed relatively easily. Further, the pan 3 does not come into contact with the inner body 8 due to the presence of the inner body spacer 43.

When the pot 3 is housed in the pot accommodating portion 6 and the flange portion 3a is supported by the pan spacer 36 and the support convex portion 37, the sensor portion 17a of the side sensor 17 is pressed against the outer peripheral surface of the second cylindrical portion 3c of the pan 3. To do. The pot 3 is pressed diagonally backward by the side sensor 17. The pressed pan 3 is brought into contact with the outer peripheral surface of the first cylindrical portion 3b with the front surface 45a of the protruding portion 45 of the first inner body spacer 43a. As a result, the pot 3 is positioned so that its center position coincides with the center position of the pot accommodating portion 6. Further, in addition to the side sensor 17, a rubber piece is pressed against the lower side of the pan 3 and the outer peripheral surface of the second cylindrical portion 3c. The side sensor 17 and the rubber piece are arranged in four equal parts in the circumferential direction. As a result, the pot 3 is evenly supported by the second cylindrical portion 3c, and the supported state of the pot 3 is stabilized. As described above, the side sensor 17 plays a role of supporting the pot 3 between the first inner body spacer 43a that abuts on the first cylindrical portion 3b and the rubber piece that abuts on the second cylindrical portion 3c.

FIG. 8 is a block diagram showing the electrical wiring of the rice cooker according to the present embodiment. A cord reel 23 is electrically connected to the IH board 19, and power is supplied from a commercial power source. The power supply board 13 is electrically connected to the IH board 19. The power supply board 13 lowers the voltage (100V) of the electric power input from the IH board 19 (for example, 20V and 5V). The electric power dropped by the power supply board 13 is returned to the IH board 19. The IH board 19 is electrically connected to the battery board 50. A voltage-dropped electric power (to 20 V) is input to the battery substrate 50, and the fan 21 is driven based on this input electric power. Further, a display board 51 provided on the lid 2 is electrically connected to the battery board 50. The display board 51 displays the display unit 5 or the like by the electric power of the voltage drop (to 5 V) input from the battery board 50. The IH substrate 19 is electrically connected to the resonance substrate 20. The resonance substrate 20 is electrically connected to the terminal block substrate 14. The terminal block board 14 controls energization of the two coils 25 based on the voltage dropped (to 20 V).

The rice cooker having the above configuration is, for example, a small rice cooker such as 3 go cooker or 5.5 go cooker. In this rice cooker, the rice cooking process is started by operating the rice cooking switch 4. In the rice cooking process, a high frequency current is supplied from the IH substrate 19 to the coil 25 at the following timing controlled by the resonance substrate 20 to perform the rice cooking process.

That is, a high-frequency current is applied only to one coil 25, and the pot 3 is induced and heated in the bottom half (first range) corresponding to the coil 25. As a result, the first range of the pot 3 becomes a heating region, and convection occurs in the vertical direction. Similarly, a high-frequency current is applied only to the other coil 25, and the pot 3 is induced and heated by the other half (second range) on the bottom surface side corresponding to the coil 25. As a result, the second range of the pot 3 becomes a heating region, and convection occurs in the vertical direction. The pan 3 is accurately positioned at the center of the pan accommodating portion 6 by being pressed by the side sensor 17 and having the first cylindrical portion b abut on the first inner body spacers 43a at two locations. Therefore, the first range and the second range, which are the heating regions of the pan 3, can be accurately and evenly positioned with the second center line CL2 in between. As a result, each coil 25 can accurately induce and heat half of the first range and the second range on the bottom surface side of the pot 3 alternately.

In this way, by alternately energizing the two coils 25, convection occurs alternately in the vertical direction in the half region of the pan 3, and the convection state can be complicated. Therefore, an excellent stirring effect can be obtained as compared with the case of heating with a single coil 25, and it is possible to draw out the umami component (eluted sugar content, etc.) contained in the rice.

According to the rice cooker having the above configuration, the following effects can be obtained.

(1) Since the pot 3 housed in the pot storage part 6 can be supported in a well-balanced manner at three places by the first inner body spacer 43a and the side sensor 17, the pot 3 is arranged at the center of the pot storage part 6. be able to. Therefore, the coil 25 enables the induction heating of each half of the pot 3 accurately and alternately. That is, the pot 3 can be heated evenly in a well-balanced manner, and good rice cooking can be realized.
(2) The side sensor 17 can be used for positioning the pot 3 in the pot accommodating portion 6. The side sensor 17 is configured to urge the pot 3. Therefore, as long as the inner surface positions of the protruding portions 45 of the first inner body spacers 43a at the two locations are set accurately, only the pot 3 is housed in the pot accommodating portion 6, and the coil 25 evenly heats each half. be able to.

The present invention is not limited to the configuration described in the above embodiment, and various modifications can be made.

In the above-described embodiment, the case where the configuration of the present invention is adopted in a rice cooker has been described, but not limited to the rice cooker, other cooked foods (for example, stewed foods such as beef stew and cream stew) are heated. It can be used in various cookers such as those for cooking.

In the above embodiment, the first inner body spacer 43a is provided at two places, but it may be provided at three or more places. Further, the inner body spacer 43 may be a separate body from the shoulder member 9, but may be integrally formed.
