Description

[Detailed explanation of the idea] Technical field This invention relates to a heating cooker.

Prior art A heating cooking device such as a microwave oven has a vertically long structure to reduce the installation area, and an operation panel is placed below a door that covers the front opening of the cooking chamber so that it can be opened and closed. In this case, when food is spilled when taking food into and out of the cooking chamber, or when juice is blown out during cooking, the spilled liquid flows down from the cooking chamber onto the control panel.
There was a drawback that the push button or operating shaft of each switch entered the interior of the heating cooker through the through hole. In order to solve this problem, the operation panel can be recessed to the rear of the front opening of the heating cooking chamber, but this causes the problem that the display on the operation panel surface becomes difficult to see and the operability deteriorates. be.

Purpose This invention was made in view of the above-mentioned problems, and its purpose is to prevent spilled juice from entering the inside of the heating cooker, which may impair operability. The purpose of the present invention is to provide a new heating cooker that does not require a heat cooker.

Structure of the invention In order to achieve these objectives, in this invention, a synthetic resin operation panel is placed below the door that can be opened and closed to cover the front opening of the heating cooking chamber, and is slanted so as to face diagonally upward. At the same time, an eave-like protrusion that faces the lower end surface of the door and protrudes forward is integrally provided at the top of the operation panel, and radio waves are absorbed within the eave-like protrusion approximately parallel to the lower end surface of the door. In addition to accommodating the members, a hole through which the operating member passes through the inclined surface of the operation panel is arranged behind the tip of the protrusion, and an annular protrusion is formed around the hole.

Embodiment Hereinafter, an embodiment embodying this invention will be described based on the drawings. As shown in FIGS. 1 and 2, an oven 2 is provided inside the outer box 1 of the heating cooker.
is arranged, and the inside thereof is a heating cooking chamber 2a with an open front. At the front of the oven 2, a door 3 that can open and close the front opening of the heating cooking chamber 2a is rotatably supported by a pair of horizontal shafts 4 provided on both left and right sides of its lower end. In addition, both horizontal axes 4
are supported by front protruding portions 21a of a pair of left and right support plates 21 that are fixed upright between the outer box 1 and the oven 2.

Below the door 3, on the front surface of the outer box 1, an operation panel 5 made of synthetic resin extending from side to side is arranged so as to face diagonally upward at the rear, and on the front side, display characters for operation are written. An aluminum plate 6 is attached. A metal switch mounting plate 7 is fixed to the rear side of the operation panel 5 and extends horizontally in parallel with the operation panel 5. As shown in FIGS. 3 and 4, the back side of the switch mounting plate 7 is A changeover switch 9 for switching the heating means and a time switch 8 for adjusting the heating time are installed at different positions on the left and right sides. The operation panel 5 is connected to the switch mounting plate 7 by a fastener 23 via a plurality of connecting rods 22 protruding from the back surface of its upper end, and a horizontal plate protruding rearward from its lower end. It is fixed to the front end of the bottom plate 1a of the outer case 1 with a screw 25 via a portion 24.

On the other hand, an eave-shaped protrusion 10 is integrally formed at the upper end of the operation panel 5 so as to protrude forward, facing the lower end surface of the door 3 in the closed state and extending from side to side. Within this protrusion 10, its horizontal portion 10a
A radio wave absorbing member 17 made of rubber ferrite is interposed between the front protrusion 7a of the switch mounting plate 7 and the front protrusion 7a.

In addition, at approximately the center in the vertical direction of the operation panel 5, a hole 11 through which a push button 9a serving as an operation member of the changeover switch 9 passes, and a hole 11 located behind the tip edge of the protrusion 10, and a hole 11 through which a push button 9a as an operation member of the changeover switch 9 passes, A hole 13 through which an operating shaft 8a as a part of the operating member passes through is provided in each case. Through holes 6a and 6b are formed in the aluminum plate 6 at positions facing these holes 11 and 13, respectively, and annular protrusions 12 and 16 are provided around the front surfaces of these through holes 6a and 6b. . The operating shaft 9b of the changeover switch 9 and the operating shaft 8a of the time switch 8 are each provided to be substantially orthogonal to the operating panel 5, and the front end of the operating shaft 8a of the time switch 8 is provided with the hole 13 and the through hole 6b. An operating knob 14 having a larger diameter than the holes 13 and 6b is attached to cover the holes 13 and 6b from above.

In the heating cooker of this embodiment configured as described above, if food juice spills when food is taken out or taken out or heated, the liquid flows downward through the gap between the door 3 and the front of the oven 2. However, according to the heating cooker of this embodiment, the protrusion 10 that protrudes forward beyond the through holes 6a, 6b and the holes 11, 13 is formed in the operation panel 5, so that the dashed line in FIG. As shown, the juice spilled from above the changeover switch 9 portion flows down from the front edge of the protrusion 10 onto the aluminum plate 6 through the front of the push button 9a of the changeover switch 9. Therefore, unlike the conventional
The spilled juice enters the inside of the heating cooker through the through hole 6a of the aluminum plate 6 and the hole 11 of the operation panel 5,
There is no risk of accumulation on the bottom plate 1a of the outer box 1 and making it unclean, and there is no inconvenience that the changeover switch 9 will be damaged by entering into the changeover switch 9 through the push button 9a and the operating shaft 9b.

In addition, as shown in Fig. 4, the time switch 8
In the part, there is a hole 1 through which the operating shaft 8a passes.
3 and the through hole 6b of the aluminum plate 6 are arranged behind the protrusion 10, and the holes 13, 6
Since the operating knob 14 is provided so as to cover the protrusion 10 from above, the juice that flows down from the tip edge of the protrusion 10 is absorbed by the operating knob 14 as shown by the chain line in the figure.
There is no risk of the water flowing down and flowing into the cooking device through the through hole 6b and hole 13. Furthermore, in each of the switches 8 and 9, annular protrusions 12 and 16 are formed around the through holes 6a and 6b of the aluminum plate 6, so that spilled juice is transmitted along the lower surface of the protrusion 10. Even if it flows over the aluminum plate 6,
The annular protrusions 12 and 16 can reliably prevent juice from entering the inside.

Incidentally, as mentioned above, in order to prevent spilled juice from entering, it is possible to provide the operation panel 5 by recessing it backwards from the lower position of the door 3, but in this case, the operation indicated on the aluminum plate 6 A problem arises in that the display becomes difficult to see and the operability deteriorates. However, as in this embodiment, the operation panel 5 is arranged so as to face diagonally upward rearward, and the operation shafts 8a, 8a of both the switches 8, 9,
If the push button 9b is provided orthogonally to the operation panel 5, the push button 9a, the operation knob 14, and the display surface face upward, so there is no problem in operation.

Furthermore, the protrusion 10 is made of synthetic resin for the operation panel 5.
Since it is provided integrally with the protrusion 10, the radio wave absorbing member 17 can also be housed and arranged using the space created within the protrusion 10.

Note that this invention is not limited to the configuration of the above-mentioned embodiment. For example, as shown in FIG. Since the protruding edge 15 functions as a drain, it is possible to reliably prevent spilled juice from flowing down the lower surface of the protrusion 10 onto the aluminum plate 6.

Effects As detailed above, this invention places a synthetic resin operation panel slanted backwards and upwards below the door that covers the front opening of the cooking chamber so that it can be opened and closed. An eave-like protrusion that faces the lower end of the door and protrudes forward is integrally provided at the top of the operation panel, and a radio wave absorbing member is housed within the eave-like protrusion approximately parallel to the lower end of the door. In addition, by arranging the hole through which the operating member passes through the inclined surface of the operation panel behind the tip of the protrusion, and forming an annular protrusion around the hole, the inside of the protrusion can be effectively used. It is easy to use, has an easy-to-operate structure, and has the effect of reliably preventing spilled juice from entering the interior.
