  The operation panel 30 which is an operation part is provided in the location depressed from the outline of the rice cooker main body 11. That is, a rectangular recess 35 that is recessed rearward is formed on the front surface of the outer case 15, and the operation panel 30 is substantially perpendicular to a portion of the recess 35 that is recessed rearward from the front surface of the outer case 15. It is arranged. The attachment is made in a state where the upper end is inclined rearward, that is, at an acute angle with respect to the floor surface F. By tilting the operation panel 30 in this way, user visibility is improved.

  By disposing the operation panel 30 on the rear side of the front surface of the outer case 15, the upper end of the recess 35 has an eaves shape, and even if it spills, water or a towel does not hang directly on the operation panel 30. A magnet 36 (see FIG. 6) for fixing the panel member 40 is attached above the operation panel 30.

  A panel member 40 that is a panel cover is provided on the front side of the operation panel 30 so as to cover the operation panel 30. The panel member 40 is a rectangular part that is slightly smaller than the rectangular recess 35, and enters the recess 35 when closed to form an outer shell on the front side of the outer case 15, as shown in FIG. And the upper surface becomes flush with the upper surface of the operation panel 30, and when the lid body 12 is opened, the appearance of the upper surface is refreshed to improve the appearance.

  The panel member 40 has a three-layer structure (see FIG. 2) of a transparent resin 40a, a sheet 40b, and an opaque resin 40c arranged from the outside to the inside, and between the sheet 40b and the opaque resin 40c. A plurality of internal spaces 41 are formed to insulate the operation panel 30.

  The transparent resin 40a is a portion that forms an outer shell, and includes three penetrations through which the second rice cooker switch button 42a, the second heat retention / cancellation switch button 42b, and the second reservation switch button 42c, which are the second switch buttons 42, penetrate. A hole 43 is provided and light from the display means is transmitted. In addition, the 2nd rice cooking switch button 42a, the 2nd heat retention / cancellation switch button 42b, and the 2nd reservation switch button 42c are the same shape, and the part which protrudes outward is a rectangular shape (refer FIG. 4), and protrudes inward. The portion has a circular shape (see FIG. 5).

  Necessary characters are printed on the sheet 40b (see FIG. 4) and can be visually observed through the transparent resin 40a. Similarly to the opaque resin 40c described later, three holes (not shown) through which the second rice cooking switch button 42a, the second heat retention / cancellation switch button 42b and the second reservation switch button 42c penetrate, the rice cooking lamp 31aa, and the heat insulation lamp Three through holes (not shown) for passing light from 31bb and the reservation lamp 31cc, and one rectangular hole (not shown) for passing light from the liquid crystal display unit 32 are provided.

  The opaque resin 40c includes three through holes 44 through which the second rice cooking switch button 42a, the second heat retention / cancel switch button 42b, and the second reservation switch button 42c penetrate, the rice cooking lamp 31aa, the heat retention lamp 31bb, and the reservation lamp. There are provided three through holes 45 through which light from 31 cc passes and one rectangular hole 46 through which light from the liquid crystal display unit 32 passes.

  And the 2nd rice cooking switch button 42a, the 2nd heat retention / cancellation switch button 42b, and the 2nd reservation switch button 42c are incorporated in the unit form including the spring which is not illustrated in the opaque resin 40c, and the rectangular shape is normal. The tip of the shape protrudes outward from the transparent resin 40a. When the rectangular tip is pressed by the user, it is pushed inward, and the opposing rice cooking switch button 31a, the heat retention / cancellation switch button 31b or the reservation switch button 31c is pressed. When the user releases the pressure, the spring returns to the position before the pressure.

  Two rotating shafts 47 projecting in the left-right direction are provided below the back side of the panel member 40 (see FIG. 5). These two rotary shafts 47 are fitted into two bearing portions 48 (see FIG. 2) provided below the operation panel 30. When the rotary shaft 47 is fitted into the bearing portion 48, the panel member 40 is pivotally supported around the rotary shaft 47 below the rotary shaft 47, and completely covers the operation panel 30 in the closed state (FIG. 3). reference). The rotating shaft 47 and the bearing portion 48 may be arranged in the opposite manner.

  A magnet 49 (see FIGS. 4 and 5) is attached above the back side of the panel member 40. When the panel member 40 is closed, the magnet 49 is attracted to the magnet 36 of the operation panel 30, and the panel The member 40 is fixed in the closed position. Recesses 50 for handles are respectively formed above both side surfaces of the panel member 40. When the panel member 40 is opened, the panel member 40 is pulled by pulling this handle recess 50 with a finger. Will be released. The fixing means may be other than the magnet.

  When the panel member 40 is closed, the panel member 40 is set to be perpendicular to the floor surface F or parallel to the operation panel 30. Therefore, when the panel member 40 is closed, the panel member 40 and the operation panel 30 form a double panel structure. Furthermore, since a gap is generated between the panel member 40 and the operation panel 30, a double heat insulating space is formed by the gap and the internal space 41 in the panel member 40, and the heat insulating effect is further enhanced.

  Further, when the panel member 40 is opened, the panel member 40 is 90 degrees or more with respect to the operation panel 30, that is, the opening / closing angle of the panel member 40 is 90 degrees or more. Then, the panel member 40 is inclined with respect to the floor surface F as shown in FIG. By the way, when the panel member 40 is parallel to the floor surface F when the panel member 40 is opened, there is a case where an object is placed thereon. When an object is placed, there is a risk that the panel member 40 is broken or the rice cooker body 11 falls from the shelf. However, if the panel member 40 is inclined as described above, the object slides down when an object is placed on the panel member 40, so that the object cannot be placed on the object, and as a result, the object is placed on the object. This can eliminate the harmful effects.

  When the panel member 40 is closed, the rectangular hole 46 of the panel member 40 faces the liquid crystal display unit 32, and the three through holes 45 face the rice cooking lamp 31aa, the heat retaining lamp 31bb, and the reservation lamp 31cc. The display of the liquid crystal display part 32 and the on / off of the rice cooking lamp 31aa, the heat retaining lamp 31bb, and the reservation lamp 31cc can be visually recognized through the member 40. The number of display means that can be displayed through the panel member 40 may be reduced.

  When the panel member 40 is closed, the panel member 40 is provided with fewer switch buttons than the switch buttons provided on the operation panel 30. That is, a rice cooking switch button 31a, a heat retention / cancellation switch button 31b and a reservation switch button 31c provided on the operation panel 30 which are used relatively frequently, The cooking time 33 which is the second reservation switch button 42c and is displayed on the operation panel 30 is hidden.

  As a result, the outer surface of the panel member 40 is in a simple and clean state, and the appearance of the operation system can be simplified and can be clearly displayed. Since the cooking time 33 is hidden when the panel member 40 is closed, more information can be written on the operation panel 30. Further, as described above, since only the switch button that is used relatively frequently is arranged on the panel member 40, for example, the hour / minute switch button 31d or the menu switch button 31e is mistakenly pressed to perform incorrect cooking. Can be prevented.

  FIG. 7 shows a state where the chamomile stand 51 is attached. The chamo-ji stand 51 has a main body 51a having an upper and lower opening 51aa for vertically sandwiching an unillustrated chamo-ji and an insertion portion 51b, and the insertion portion 51b is inserted into an opening 52 provided at the bottom of the rice cooker main body 11. Then, a screw is inserted into a screw hole 51c provided in the insertion part 51b and fixed in the rice cooker body 11.

  When the chamomile stand 51 is attached, the chamomile (not shown) is inserted into the upper and lower openings 51aa of the main body 51a as shown in FIG. In addition, by forming the chamo-ji stand 51 in such a form, the chamo-ji stand 51 having a simple structure can be formed. Moreover, the opening 52 can be formed larger and used together as a hole for releasing heat or a buzzer sound.

  By the way, since the above-mentioned electric rice cooker 10 is provided with a relatively large rectangular operation panel 30 on the entire surface of the rice cooker body 11, the lid 12 is provided with a lid opening / closing mechanism H including a push button 29 or the like. The lid opening / closing mechanism H will be described below.

  Since the push button 29 is opened when the lid 12 is opened when the push button 29 for opening and closing is provided on the upper surface of the lid 12, the engaging claw 57 d at the tip of the engagement lever 57 is opened before the lid 12 is opened. May re-lock to the lid locking portion 58 on the rice cooker body 11 side, and the lid 12 may not open. In order to prevent such re-locking, for example, as shown in Japanese Patent Application Laid-Open No. 2000-14538, there is one provided with a baffle plate. However, since such a thing pushes a baffle plate with the engagement lever 57, opening and closing is not performed smoothly.

  Therefore, a shutter lever 60 that moves the shutter 65 up and down is provided in addition to the engagement lever 57 that is pushed down by the push button 29, and when the push button 29 is moved down, the shutter 65 is moved up and the engagement lever 57 is moved. The engagement between the locking claw 57d and the lid locking portion 58 of the rice cooker body 11 is released, and after the release, the shutter 65 engages with the lid locking portion 58 and the locking claw 57d and the lid locking portion are engaged. Means for preventing re-locking with the portion 58 are provided.

  The lid opening / closing mechanism H is a resin member having a push button 29, an engagement lever 57, a shutter lever 60, a shutter 65, and the like. Each member is shown in FIG.

  The push button 29 is a rectangular member in a plan view having a main body portion 29a and a flange portion 29b extending in the left-right direction of the main body portion 29a, and is a hat-shaped member in the vertical section. An opening 29c is provided. The opening 29c is fitted to a shaft 55 (see FIG. 12) standing from the lid body 12 via a spring (not shown), and is always moved upward by the spring after the fitting. Further, the upward movement is restricted by a stopper 55a (see FIG. 12).

  The engaging lever 57 is a member having a square cross-sectional shape having a pressing portion 57a and a supporting portion 57b, and has a bearing portion 57c at a portion bent at a right angle. The bearing portion 57c is fitted to a horizontal shaft 59 (see FIG. 9) attached to the lid 12 in a horizontal state, and supports the engagement lever 57 so as to be rotatable. Further, a rectangular opening 57e is provided at the center of the support portion 57b, and a locking claw 57d having a substantially right angle toward the inside is formed at the tip of the support portion 57b.

  A lid locking portion 58 (see FIG. 11) is provided on the upper surface on the front side of the rice cooker body 11, and when the lid 12 is closed, the locking claw 57d is connected to the lid locking portion 58. Engage with. The engaging lever 57 is given a counterclockwise force by a first lever spring 57f (see FIGS. 9 and 11). When the push button 29 is pushed down, the engagement lever 57 rotates clockwise about the horizontal shaft 59 to release the engagement between the locking claw 57d and the lid locking portion 58.

  The shutter lever 60 has a symmetrical shape, is a member with a square cross section having a pressing portion 60a and a rod-like portion 60b, and has a bearing portion 60c at a portion bent at a right angle. And the two parts of the same shape are connected by the horizontal connection part 60d.

  The engagement lever 57 is fitted between the bearing portions 60c, and the horizontal shaft 59 is fitted. A spring support portion 60e is provided at the center of the connecting portion 60d, and a second lever spring 60f that applies a counterclockwise force to the shutter lever 60 is provided on the spring support portion 60e.

  As a result, the shutter lever 60 is sandwiched between the engagement levers 57 and is rotated separately from the engagement levers 57. When the push button 29 is pushed down, the shutter lever 60 rotates clockwise about the horizontal shaft 59 and releases the contact of the shutter 65 with the placement portion 65aa. Then, as will be described later, the shutter 65 is moved upward, and the horizontal upper surface 65bb is fitted into the lid locking portion 58, thereby preventing the locking claw 57d and the lid locking portion 58 from being re-locked.

  The shutter 65 is a substantially H-shaped member having a vertical portion 65a and a horizontal portion 65b, and an arcuate placement portion 65aa is formed at the upper end of each vertical portion 65a. A spring case 65c is integrally formed on the lower surface of 65b so as to hang down, and a shutter spring 65d (see FIGS. 9 and 11) is inserted inside to apply a force to move upward to the shutter 65. Yes. When the shutter 65 moves up, the horizontal upper surface 65bb of the horizontal portion 65b is fitted into the lid locking portion 58, and the locking claw 57d and the lid locking portion 58 are prevented from re-locking.

  When the lid 12 is closed, as shown in FIG. 10, the rod-like portion 60 b of the shutter lever 60 is placed on the placement portion 65 aa of the shutter 65 to press the shutter 65 downward. .

  As shown in FIGS. 10 and 11, the engagement lever 57 has a gap t larger than the shutter lever 60 with respect to the push button 29. Therefore, when the push button 29 is pushed down, the shutter lever 60 is first pushed, and then the engagement lever 57 is pushed. First, the contact between the rod-like portion 60b and the shutter 65 is released, and then the engagement between the locking claw 57d and the lid locking portion 58 is released, whereby the horizontal upper surface 65bb of the shutter 65 is used for the lid. This is to make it easier to fit the locking portion 58.

  That is, when the push button 29 is pushed down, the shutter lever 60 is first pushed, and the shutter lever 60 is rotated clockwise to release the contact between the rod-like portion 60b and the placement portion 65aa of the shutter 65. Thus, the upward movement of the shutter 65 is allowed.

  The engagement lever 57 is pushed slightly after this movement. Then, the engagement lever 57 rotates clockwise, and the engagement between the locking claw 57d and the lid locking portion 58 is released. Then, the horizontal upper surface 65bb of the shutter 65 is quickly fitted into the lid locking portion 58. As a result, the locking claw 57d and the lid locking portion 58 are prevented from re-locking.

  When the push button 29 is released, the shutter lever 60 is first rotated counterclockwise by the second lever spring 60f. Then, the rod-like portion 60 b of the shutter lever 60 pushes down the shutter 65 and releases the engagement between the shutter 65 and the lid locking portion 58. The engagement lever 57 is rotated counterclockwise by the first lever spring 57f with a slight delay. Then, the locking claw 57d is fitted into the lid locking portion 58, and the lid body 12 is closed.

  As described above, since the lid opening / closing mechanism H is made of resin parts, it is easier to obtain accuracy when assembled than metal parts, and variations among the parts are also reduced. In addition, since the engaging lever 57 and the shutter lever 60 are configured separately, the shutter 65 does not push the engaging lever 57 during the operation of closing the lid 12, so that the movement of the engaging lever 57 becomes smooth.

  In addition, since the engaging lever 57 and the shutter lever 60 are configured separately, the shutter 65 does not press the engaging lever 57 when the lid 12 is closed, so that the movement of the engaging lever 57 when the lid is opened is reduced. Smooth.

  Further, since the engaging lever 57 and the shutter lever 60 share the horizontal shaft 59, both levers can be incorporated in a small space and the number of parts is reduced.

  Further, when the lid 12 is opened, the shutter 65 becomes an auxiliary biasing force that opens the lid 12, and the opening thereof becomes smooth.

  The invention of the present application is not limited to the configuration of the above embodiment, and it is needless to say that the design can be appropriately changed without departing from the gist of the invention.
