However, in the case of the heating cooker described in Patent Document 1, the operation module is stored by the first rotation mechanism for rotating the opening / closing panel and the second rotation mechanism for rotating the operation module with respect to the opening / closing panel. It is put in and out of the space. Further, in order to link the opening / closing panel and the operation module in a predetermined manner, it is necessary to synchronize the first rotation mechanism and the second rotation mechanism. Therefore, the configuration for storing the operation module is complicated.

In order to solve this, in a heating cooker having an operation unit, the operation unit extends in the left-right direction of the unit main body having a storage space open on the front side of the operation unit and the operation unit. The first rotation shaft is provided with an opening / closing panel that is attached to the unit main body so as to be tiltable toward the front side of the operation unit with the first rotation axis as a center and opens / closes the storage space, and a user interface surface.

As a result, the opening / closing panel 6 is rotatably supported by the operation unit main body 5 via the support pin 12 (C1 axis). As a result, the opening / closing panel 6 can rotate about the first rotation shaft C1 with respect to the operation unit main body 5 and tilt forward.

FIG. 9 is an exploded perspective view of the movable unit 9 in the operation unit 4.

As shown in FIG. 9, the movable unit 9 includes an opening / closing panel 6 and an operation module 8. Further, in the case of the present embodiment, the movable unit 9 includes a torsion spring (urging member) 13, a left side cover 14, a right side cover 15, a support pin 16 (C2 axis), and a flap 17. ..

Specifically, the operation module 8 is rotatably attached to the opening / closing panel 6, and the left side cover 14, the right side cover 15, and the flap 17 are attached to the opening / closing panel 6. The left side cover 14 and the right side cover 15 are fixed to the base portion 6a of the opening / closing panel 6 by the screws 18. The operation module 8 rotates between the left side cover 14 and the right side cover 15.

The flap 17 is attached to the recess on the upper surface of the opening / closing panel 6, and the tip is arranged so as to fit in the gap formed between the upper surface and the lower surface of the operation module 8 from the closed time to the open time. There is.

In order to realize both the behavior of the opening / closing panel 6 and the behavior of the operation module 8 by the torsion spring 13, as shown in FIG. 10, the operation unit main body 5 has a guide portion 5g for guiding the rear end of the operation module 8. Is provided. In the case of this embodiment, two guide portions 5g are provided. Further, in the case of the present embodiment, FIG. 11 is a perspective view of the operation module showing the shaft 11 and the roller 19, and as shown in FIG. 11, as the rear end of the operation module 8 guided by each of the guide portions 5g. Two rollers 19 are provided on the operation module 8.

As shown in FIG. 10, in the case of the present embodiment, the guide portion 5g of the operation unit main body 5 is a rib formed on the rear side wall 5b. The rear side wall 5b has an overhang shape, and the upper end side portion thereof functions as a ceiling defining the storage space 11a. A guide portion 5g is provided along the overhang-shaped rear side wall 5b. That is, the guide portion 5g is also overhanging.

In the case of the present embodiment, the roller 19 of the operation module 8 shown in FIG. 11 rolls the rib-shaped guide 5g. In this embodiment, the roller 19 is rotatably supported by the shaft 11.

12 and 13 are cross-sectional views of the operation unit showing the positions of the rollers of the operation module that change depending on the state of the opening / closing panel, and show the mechanism when the operation module is rolled when the operation unit is opened / closed. 14 and 15 are cross-sectional views of an operation unit showing the position of the shaft of the operation module which changes depending on the state of the opening / closing panel like the roller. Note that, in FIGS. 12, 13, FIGS., and 15, the components in the operation module 8 are not shown.

As shown in FIG. 12, the guide portion 5g has an overhang shape, that is, extends substantially upward from the bottom in the vertical direction, and then extends in the upward direction and extends in the forward direction. And it extends forward. As a result, as shown in FIGS. 12 and 13, the roller 19 that rolls on the guide portion 5 g moves only in the upward direction and the forward direction when the opening / closing panel 6 moves from the fully closed position to the fully open position. .. As a result, the storage space 5a of the operation unit 4 can be reduced, that is, the roller 19 does not move backward from the position when the opening / closing panel 6 is in the fully closed position, so that the storage space 5a of the storage space 5a can be reduced. The size in the front-rear direction can be reduced, and the operation unit can be miniaturized.

However, as described above, by providing the first rotation axis C1 and the second rotation axis C2 in order to reduce the storage space 5a, the movable unit 9 is newly stored, and the flap 17 and the lower surface of the interface 7 are newly provided. A flap passage hole 8f is formed as a space between the two.

FIG. 16 is a cross-sectional view at the time of closing, and FIG. 18 is a cross-sectional view at the time of opening. It relates to the configuration related to the discharge route.

First, liquid leakage will be described.

FIG. 13 shows a discharge route of the leaked water that has entered the operation unit 4 in the fully closed state. Details of the figure, particularly the first flow path when fully closed, are shown in FIG. The first flow path is a flow path until water leakage from the outer surface of the operation module passes through the through hole 6h penetrating the base portion 6a, and this mechanism prevents water leakage into the operation module. Leakage is, for example, top plate 2
It is a liquid that is generated by spilling from a cooking container that is placed on top and heated with liquid, or by accidentally turning over a pot that contains liquid during cooking.

As shown in FIG. 16, the leaked water that has entered the operation unit 4 enters the waterproof space 8 g of the operation module 8 through the flap 17 and through the flap passage hole 8f. The waterproof space 8g is independent of the electronic component accommodating space 8h in which the electronic components and circuit boards related to the operation are accommodated, and does not communicate with the electronic component accommodating space 8h.

The water leak that has entered the waterproof space 8g is discharged to the outside of the operation module 8 through the discharge hole 8j formed in the operation module 8. As shown in FIG. 16, the discharged water leak flows on the chute portion 8k of the operation module 8. The position of the chute is arranged so that the chute 8k faces when the hole on the opening / closing panel 6 is looked up from vertically below regardless of whether the operation module 8 is open or closed. is doing.

Leakage directed by the chute portion 8k and flowing down from the chute portion 8k passes through the through hole 6h penetrating the base portion 6a of the opening / closing panel 6 and enters the discharge flow path 6j between the opening / closing panel 6 and the decorative panel 10. Inflow. As a result, water leakage is accumulated in the operation module 8, and the accumulated water leakage is suppressed from entering the electronic component accommodating space 8h.

As shown in FIG. 18, even in the fully open operation unit 4, the leak is discharged by the same route as the fully closed operation unit 4. The details of the figure, particularly the first flow path when fully opened, are shown in FIG. As a result, the intrusion of water into the electronic component accommodating space 8h of the operation module 8 is suppressed.

The chute portion 8k is shown in the perspective view of the operation module of FIG.

Therefore, the liquid that has entered from the operation display surface through the upper surface of the flap 17 and through the gap between the opening / closing panel 6 and the operation module 8 is transmitted through the chute portion 8k formed in the operation module 8, and the opening / closing panel 8 is opened. It has a function of being able to be discharged to the outside by passing through a discharge path of a gap between the opening / closing panel 6 and the decorative panel 10 through a hole.

With respect to the inclusion of foreign matter other than liquid, the basic discharge route is the same as the WP shown in FIG. 16 or FIG.

Foreign matter other than liquid is mixed when, for example, a toothpick used during cooking is dropped on the upper surface of the operation unit.

As shown in FIG. 16, foreign matter other than the liquid that has entered the operation unit may invade in the process from the closing time to the opening time. It is assumed that the size of the intruder is smaller than the width of the discharge path 6j in the left-right direction and smaller than the height of the discharge path 6j in the front-rear direction.

FIG. 21 shows a perspective view of an opening / closing panel and an operation module showing a configuration related to a discharge path of foreign matter other than liquid in the operation unit.

Regarding the intrusion route, the place where the flap 17 penetrates to the point where it passes through the through hole 6h penetrating the base portion 6a of the opening / closing panel 6 is the same as the liquid leakage.

A step A having a recessed shape is formed in the base portion 6a of the opening / closing panel 6, and the step A is inclined in a substantially V-shaped D (shown in FIG. 23), and the step surface left 6k through the through hole. It is composed of 6 liters on the right side of the stepped surface of the through hole. The positional relationship is asymmetrical, and the position of the through hole step left 6k is higher than the through hole step right 6l. The positional relationship of the height difference may be reversed left and right.

As shown in FIG. 22, the foreign matter C other than the liquid comes into contact with the through hole step surface left 6k and then with the through hole step surface right 6l. At this time, due to the height difference B of the step, the rotation is centered on the step angle left 6 m forming the left corner of the step surface of the through hole, and the tip of the foreign matter C other than the liquid faces the discharge path 6j side. After that, it flows into the discharge path 6j and is discharged to the outside of the operation unit 4 from the discharge hole 6n provided on the lower surface of the opening / closing panel.

As shown in FIG. 23, in the above mechanism, when the positional relationship between the through hole step surface left 6k and the through hole step surface right 6m is symmetrical and there is no height difference B of the step, the foreign matter C other than the liquid is the through hole 6h. Since there is no rotation mechanism for foreign matter other than liquid to rotate in the substantially V-shaped step when it penetrates and passes parallel to the long side, it is arranged horizontally and gets stuck on the upper part of the V-shape. In order to prevent the above, a height difference B is provided on the step A of the base portion 6a of the opening / closing panel 6.

Regarding the shape of the step A having a substantially V-shape D, since the operation unit has a speaker, the left-right width of the discharge flow path 6j is made smaller than the through hole 6h, and the height difference B of the left-right asymmetric step is provided. Although it is necessary, it is peculiar to the shape of this operation unit, and if the left and right width of the discharge path 6j can be secured to the same size as the through hole 6h, the height difference B of the step of the substantially V-shaped D is not provided. You may.

An operation module (operation unit) having a user interface surface provided with buttons for user operation can be applied to a cooking device that can be stored on the side surface of the main body.
