Description

The present invention relates to a heating cooker that heats a heated cooking container placed on a top plate.

In general, in this type of cooking device, a radial heater such as an induction heating coil or an electric coil is provided as a heating means in a box-shaped casing, and is placed on a top plate disposed on the upper surface facing the box. It is set as the structure which heats cooked cooking containers, such as a pot. Furthermore, it is equipped with a normal roaster means separately from the above heating means to enable cooking of grilled fish and the like,
Therefore, it is provided as a cooking device capable of cooking cooked foods and grilled foods, and has good usability in various cooking. However, in the built-in type of the heating cooker, it is incorporated by dropping into a top plate of a system kitchen or the like, and the top plate is maintained in a state of protruding on the top plate. This is a so-called drop-in method, which is a built-in means for storing the housing from above in an opening formed in the top plate.

However, a commonly used top plate made of crystallized glass made of heat-resistant glass is formed in a flat rectangular plate shape excluding an intake / exhaust portion provided at the rear of the casing. And it is set as the structure attached so that the outer periphery of a top plate including this intake / exhaust part might be covered with the flame | frame which made the metal and which was another member. Such a frame is fixed with an adhesive or the like, and when the cooking device is assembled into the kitchen top plate by dropping it, it is in contact with and supported by the opening periphery of the top surface of the top plate, or the appearance of the peripheral edge of the top plate Therefore, sufficient consideration is required for assembly accuracy (see, for example, Patent Document 1).

That is, since the built-in type heating cooker is incorporated in a kitchen having a standardized opening, its external dimensions are restricted. Therefore, although the outer shape of the dimensions of the upper cooking surface is also restricted, the size of the cooking device having a roaster is further restricted because it has an inverter cooling inlet and a roaster exhaust.

However, attaching the frame of the separate member as described above to the top plate not only has the problem of increasing the number of assembling steps, but also has a difficult appearance design, and also occurs on the top plate upper surface and the edge portion of the frame. Dirt, such as spilling, is likely to accumulate on the stepped part,
Or if the degree of adhesion of the frame is poor, it cannot enter the gap and be easily cleaned. In many cases, this frame is made of metal, but in this case, it is necessary to give sufficient consideration to safety so as not to be injured at the edge portion. He was worried about finishing up and having troublesome work.

Therefore, as a countermeasure, there has been proposed a configuration in which the frame-shaped frame is removed, that is, a configuration in which the outer peripheral edge portion is integrally formed with only a top plate made of heat-resistant glass as a frameless (see, for example, Patent Document 2). ). For example, the frameless top plate 1 integrally formed of heat-resistant crystallized glass is formed by cutting an inclined surface portion that descends outward as if the outer peripheral edge portion on the upper surface side is chamfered. There is. This suppresses the rising dimension in the thickness direction at the peripheral end portion of the top plate 1, reduces the collision during the operation of the cooking device such as the pan, and reduces the shock at the time of the collision. It is a shape that is effective and useful for safe handling. Furthermore, since the step with the kitchen top plate can be reduced,
The pan can be set by sliding it from the top of the kitchen. In addition, it has many features such as excellent cleanability and excellent appearance design.
Japanese Patent No. 3054836 Japanese Patent Laying-Open No. 2005-83639

However, there is no metal frame that protects the outer periphery of the frameless top plate.
In addition, when the pan is set on the top plate from the kitchen top plate due to the fact that the slope of the outer peripheral edge is thin, the bottom of the pan hits the side of the top plate. When the pan was dropped on the slanted surface and the bottom of the pan hit the slanted surface, the top plate might be chipped or cracked.

In order to solve the above-described problems, an object of the present invention is to provide a cooking device that prevents cracking or chipping as a frameless top plate and has a good appearance design.

A heating cooker according to the present invention includes a housing provided with heating means, a frameless top plate on which a cooked cooking container can be placed, a driving means for controlling the heating means, and an inside of the housing A roaster means provided on the heating means, an air cooling means for air-cooling the heating part of the heating means and the driving means, and an air intake part disposed at a position facing the upper side of the housing for taking in and discharging air of the air cooling means And the exhaust plate, the top plate has an inclined portion that is inclined toward the outer side surface portion, has an inclined intermediate portion that connects the inclined portion and the side surface portion, and the top plate lower frame is provided on the lower surface, said top plate, the elastic member and the housing supporting on the upper surface while being placed on the top plate are touch input unit of a touch input type is formed, the top plate A part, the electrode substrate of the touch input unit is held in the lower frame, the lower frame, the exterior member provided at the tip portion further below the lower frame and an inner of the outer member The main feature is to provide the elastic body.

According to the above means, since the inclined intermediate portion connecting the inclined portion and the outer peripheral side surface portion is formed at the outer peripheral end portion with the frameless top plate, it is possible to prevent the outer peripheral end portion of the top plate from being chipped or cracked.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a cross-sectional view of the top plate. 2 is an external perspective view of a state where the cooking device 11 is incorporated in the top plate 12 of the system kitchen (so-called built-in type), FIG. 3 is a plan view thereof, FIG. 4 is a longitudinal side view thereof, and FIG. An external perspective view of the cover is shown, and the overall configuration will be generally described with reference to FIGS.

The heating cooker 11 has a configuration including a rectangular box-shaped casing 13 having a built-in heating means, which will be described later, and an open upper surface, and a top plate 14 mounted on the upper surface. However, an opening 12a (see FIG. 4) is formed in the top plate 12 of the kitchen, and the casing 13 portion is dropped into the opening 12a. As will be described in detail later, on the back side of the top plate 14 It is the structure supported by the opening peripheral part of the top plate 12 (refer FIG. 1).

Thus, the housing 13 incorporates heating means, air cooling means, etc., which will be described later,
A roaster means 16 having a sheathed heater (not shown) is provided on the left side in front of the housing 13 shown in FIG. 2, and a door 16a that can be taken in and out is provided on the front surface thereof. (Not shown).

On the other hand, the top plate 14 constituting the upper surface of the heating cooker 11 is integrally formed in a flat rectangular plate shape made of, for example, transparent heat-resistant tempered glass (crystallized glass). The heating units 18, 19, and 20 that indicate the placement unit that is suitable for heating the cooked container such as the pan 17 are printed and displayed at three locations indicated by the circular frame lines.

Among them, the two heating units 18 and 19 on the left and right sides of the front can heat the pan 17 that is a cooking container based on induction heating coils 21 and 22 that are one of the heating means provided in the housing 13. In addition, the heating unit 20 located in the rear center is provided with a radial heater 23 made of, for example, a nichrome wire and can heat a heated cooking container such as a pan 17 through the top plate 14 to form a so-called three-necked stove. is doing.

Thus, the top plate 14 having the three heating parts 18, 19, and 20 on which the cooking container to be heated is placed is formed on a flat surface except for an area having an intake / exhaust part (described later) behind the top plate. The entire upper surface is a mounting surface on which a so-called pan 17 or the like can be mounted.

Here, the heating means and the like provided in the housing 13 will be described with reference to FIG. 4 is a cross-sectional view of the heating parts 18, 19,
20 (see FIG. 3), the heating means facing the right heating unit 18 is clearly shown, and therefore, the configuration in which the induction heating coil 21 is disposed via the coil support member 24 is shown.

However, the space below these heating means is equipped with means for driving and controlling the heating means, and a control circuit mainly comprising an inverter and a microcomputer for supplying a high-frequency current to the induction heating coils 21 and 22. A driving means 25 such as a substrate is incorporated. Such a driving means 25 is configured to include a heat-generating switching element such as an IGBT constituting the main circuit, and the driving means 25 and the induction heating coils 21 and 22 constitute an induction heating device. is doing.

Therefore, in such an induction heating device, a heat-generating switching element such as an inverter included in the driving means 25 and an air-cooling means for cooling heat-generating members such as the induction heating coils 21 and 22 are provided.

As this air-cooling means, a blower device 26 including a blower fan 26a, a fan casing 26b, a motor 26c (see FIG. 3) and the like is provided, and the taken-in outside air is blown to the heat generating member side to be air-cooled.

This air blowing action is shown in FIG. 3 and FIG.
In order to take in outside air, an intake duct 27 that faces the outside of the housing 13 is formed as an intake portion and is connected to the internal fan casing 26b. On the other hand, the downstream side, which is the discharge side of the blower 26, is blown with the internal space of the housing 13 having the driving means 25 as the closed space S1, and the exhaust air is partly outward on the rear side of the housing 13. It is provided on the way and can be discharged to the outside. In addition, a part of the blast is guided to the induction heating coils 21 and 22 side, etc.
The cooling effect by the air blowing in the direction of arrow A suppresses the temperature rise of the heat generating member.

On the other hand, in the roaster means 16 provided on the inner left side of the housing 13, another closed space S2 partitioned from the closed space S1 is formed. This is because, in the cooking of cooking, high-temperature oily smoke or the like is generated, so that it is a closed space S2 that includes the entire grill net and saucer (not shown), and an exhaust duct 28 is provided as an exhaust part connected to the rear of the closed space S2, It opens to the outside of the housing 13.

However, the intake / exhaust action in the closed space S2 is not provided with a forced air blowing means, and the exhaust duct 28 is provided on the outside side in order to promote exhaust using natural convection caused by exhaust heat such as smoke. The passage form rises as it goes to the open end. On the other hand, the intake side has a configuration in which outside air can be sucked using, for example, a gap around the front door 16a, and the intake / exhaust flow flows in the direction of arrow B shown in FIG. As a result, as shown in FIG. 3, the intake duct 27 is opened to the outside on the right side of the housing 13 as an air intake portion of the air cooling means, and the rear end of the closed space S1 as the exhaust portion of the air cooling means is on the left side. The roaster means 1 is open facing the outside and adjacent to it.
As the exhaust part 6, the exhaust duct 28 is arranged so as to open outward from the closed space S <b> 2.

However, as described above, the top plate 14 is a flat plate on which the pan 17 and the like can be placed. In this embodiment, the top plate 14 has a rectangular flat plate shape and does not cover the rear area of the casing 13 having the intake and exhaust portions. . Accordingly, in this embodiment, the rear area including the intake / exhaust portion is covered with a metallic decorative cover 29 made of a separate member. As shown in FIG. 5, the decorative cover 29 is formed by extruding, for example, an aluminum material into a basic shape.
A long hole-shaped opening 30 (indicated by reference numerals 30a and 30b, respectively) having substantially the same shape is formed by post-processing at a location. Among them, the right side opening 30a shown in FIG. 3 is located at an opposing position substantially coincident with the opening of the intake duct 27 serving as the intake section, and the left opening 30b is used for exhausting the exhaust duct 28 serving as the exhaust section and the closed space S1. At the facing position where the opening substantially coincides, the opening 30 maintains the intake and exhaust parts in an open form facing outward.

Then, the decorative cover 29 covering the intake / exhaust portion area is arranged so as to cover one side of the top plate 14 in contact with the top plate 14 as shown in FIG. 1 and protrudes upward with the opening 30 interposed therebetween. The raised portions 31 and 32 are formed in parallel, and the protruding height is formed to be sufficiently higher than the mounting surface which is the upper surface of the top plate 14. A stepped portion 33 is formed in the middle portion including the opening 30 extending in the longitudinal direction, and two vent covers 34 having a large number of vent holes are detachably fitted and supported on the stepped portion 33. .

The decorative cover 29 having such a configuration is attached using a metal lower frame 35 joined to the back surface side of the top plate 14. The lower frame 35 has a rectangular frame shape that opens a wide range including the heating parts 18, 19, and 20 on the top plate 14, and a reservoir 35a for the adhesive 36 is formed around the rectangular shape. The top frame 14 is joined to the top plate 14 with an adhesive 36, and the lower frame 35 serves as an intermediary for connecting and fixing the housing 13 as will be described later.

However, the decorative cover 29 is fastened to a flat plate-like portion in the rear area of the lower frame 35 by fastening a plurality of locations (only one location is shown in FIG. Yes. A vent hole 35b is formed at a position facing the opening 30 of the lower frame 35, and the intake / exhaust portion is formed in a communicating state.

Here, the built-in configuration by dropping the housing 13 onto the top plate 12 will be described. As clearly shown in FIG. 1, the outer peripheral flange portion 13 a (not necessarily continuous over the entire circumference) as the housing support of the housing 13. ) Is hooked on the peripheral upper surface of the opening 12a of the top plate 12 to receive a load on the housing 13 side. Then, the lower frame 35 to which the top plate 14 and the decorative cover 29 are attached is connected and fixed to the housing 13 with screws 38 at a plurality of hanging portions 35c vertically bent downward. The top plate 14 and the decorative cover 29 are configured so as to be integrated with the housing 13 and the cooking device 11 is incorporated in the top plate 12.

In addition, packing 39 which is an elastic body is joined around the back side of both the top plate 14 and the decorative cover 29. When the casing 13 is supported in a hooked state on the top plate 12, the packing 39 is slightly compressed and assembled in a crimped state, so that the gap between the outer peripheral edge of the top plate 14 and the top plate 12 is Water sealing action that prevents liquids from entering.

Further, on the surface side of the peripheral end portion of the top plate 14, an inclined surface portion 14 a that is inclined downward toward the side surface portion 14 c that forms the outer periphery of the top plate is formed.

Between the inclined surface portion 14a and the side surface portion 14c, there is formed an inclined intermediate portion 14b that is located between the two surfaces and connects the two surfaces. The inclined intermediate portion 14b is connected to the inclined surface portion 14a. It is inclined at an intermediate angle with respect to the side surface portion 14c.

  Accordingly, a similar inclined surface portion may be appropriately formed on the peripheral end portion of the decorative cover 29.

  Next, the operation of the heating cooker 11 having the above configuration will be described.

First, a procedure for assembling the top plate 12 will be described with reference to FIG. 1 in particular. As described above, the top plate 14 and the decorative cover 29 are attached and held to the metal lower frame 35 by the adhesive 36. At this time, the support portion 31 of the decorative cover 29 is firmly attached and fixed by the screws 37 so as to cover the adjacent one side of the top plate 14, and packing is provided on the peripheral edges of the back surface of the top plate 14 and the decorative cover 29. 39 is joined.

The hanging portion 35c of the lower frame 35 having the above-described assembly structure is inserted into the housing 13 in which the heating means, the blower 26, and the like are installed, and the hanging portion 35c is fastened to the housing 13 with the screw 38. Thus, the top plate 14 and the decorative cover 29 are connected and fixed to a predetermined position via the lower frame 35 with respect to the housing 13 and integrated to constitute the cooking device 11.

The heating cooker 11 is dropped (dropped) from above into the opening 12 a of the top plate 12 from the housing 13 side, and the flange portion 13 a at the upper end of the housing 13 is hooked on the opening periphery of the top plate 12 to be supported. At this time, the packing 39 is compressed and pressed onto the top plate 12. Accordingly, the flange portion 13a supports the load, the packing 39 is pressure-bonded to the top plate 12 to provide a water sealing function, and the top plate 14 and the decorative cover 29 have no load burden and are directed to the back side. The lower frame 35 increases the mechanical strength.

At this time, the top plate 14 and the top plate 12 are configured to be supported so as to have a gap 14s, and the packing 39 forms the gap 14s.

On the other hand, the cooking operation by the cooking device 11 is well known, and will be briefly described below. The operation unit 15 drives, for example, the induction heating coil 21 on the right side of the heating unit via a driving unit 25 such as an inverter, and is placed on the heating unit 18 of the top plate 14 based on a desired heating output setting operation. For example, boiled food cooking is started via the pot 17.

Along with the start of this cooking, the air blower 26 constituting the air cooling means is also driven, and the outside air taken in from the intake duct 27 is blown in the direction of arrow A as shown in FIGS.

By this ventilation, driving means 25 such as an inverter having a heat-generating switching element,
Then, after flowing through the closed space S1 having the induction heating coil 21 and the like and air-cooling the heat generating member, it is exhausted from the opening 30b side of the decorative cover 29 to the outside. On the other hand, when the roaster means 16 is used to cook a grilled food such as fish, smoke with high heat generated at that time passes through the closed space S2 partitioned separately from the above by convection. It flows in the direction of arrow B, and is naturally exhausted from the opening 30b of the decorative cover 29 via the rear exhaust duct 28.

In such practical use, boiled juice or the like is blown over the top plate 14 during cooking, or water used in the kitchen is scattered. However, in the present embodiment, the mounting surface, which is the upper surface of the top plate 14 including the heating parts 18, 19, and 20 on which the pan 17 and the like are mounted, is a so-called frameless integral body that is not equipped with a frame or the like of another member. Since it is formed, dirt can be easily wiped away. In addition, a decorative cover 29, which is a separate member, is disposed in the rear area having the intake / exhaust portion, and the intrusion of liquid or the like is prevented by the bank portion 31 protruding on the side adjacent to the top plate 14.

Further, as shown in FIG. 1 in an enlarged manner, the surface side of the frameless outer peripheral edge portion of the top plate 14 forms inclined surface portions 14a inclined downward toward the outer peripheral side surface portion 14c, and these inclined surface portions 14a. Between the two side surfaces 14c and the side surface portion 14c.
The inclined intermediate part 14b was formed.

The inclined intermediate portion 14b is inclined at an intermediate angle between the inclined surface portion 14a and the side surface portion 14c.

This is a form in which a so-called right-angled corner is cut and gradually inclined downwardly with the first inclination (inclined surface part 14a), the second inclination (inclination intermediate part 14b), and the side surface part (14c). Especially pan 17
Reduces collisions when handling heated cooking containers, etc., and exerts an action to soften shock (impact) by tilt angle even if it collides, and it is good in terms of design with no corners (edges) .

Especially when setting a pan with a right bottom from the top plate 12 to the top plate 14,
Since the inclined intermediate portion 14b is formed, the outer periphery of the top plate 14 can be formed into a rounded shape as a whole, and the edge that is an angular portion can be reduced. The chance of hitting the outer peripheral edge can be reduced, and chipping and cracking of the top plate 14 can be prevented.

  As explained above, the first embodiment has the following effects.

As described above, the top plate 14 is integrated with the lower frame 35, and the packing 39 is an elastic body.
Since the top plate 12 is assembled to the top plate 12 through the flange portion 13a which is a housing support, even if the pan is dropped on the inclined surface 14a of the top plate 14 and the bottom of the pan hits the inclined surface 14a, the impact is alleviated. Therefore, chipping and cracking of the inclined surface of the top plate 14 can be prevented. Further inclined surface part 1
Between the 4a and the side surface portion 14c, the inclined intermediate portion 14 is located between these two surfaces and connects the two surfaces.
Since b is formed and the corners (edges) of the top plate 14 are reduced, chipping and cracking can be effectively prevented.

Moreover, since it was set as the structure which has a clearance gap between the top plate 14 and the top plate 12, even if it is a case where a pan falls on the inclined surface of the top plate 14 from upper direction, since there is a clearance gap 14s, an impact is disperse | distributed, It has the effect that the inclined surface is difficult to break.

In the first embodiment, the inclined intermediate portion 14b is a linear inclined surface.
4b may be a rounded R-shaped slope. With such a configuration, there are no more edges on the inclined surface, and cracking and chipping of the top plate 14 can be effectively prevented.

(Second Embodiment)
Hereinafter, the same structure as the first embodiment will be described with reference to FIGS. 6 to 7 using the same reference numerals.

The difference from the first embodiment is that the operation unit is not provided in the front, the operation unit is formed on the top plate, and the structure of the lower frame.

The structure of the outer peripheral edge portion of the top plate 117 is the same as that of the first embodiment, and the surface side of the frameless outer peripheral edge portion of the top plate 117 is inclined downward toward the outer peripheral side surface portion 117c. The surface portion 117a is formed, and the inclined surface portion 117a and the side surface portion 117c are formed.
Between the two, an inclined intermediate portion 117b is formed, which is located between these two surfaces and connects the two surfaces.

A different point is that a touch input type (capacitance type) touch input unit 117 s is formed on the front end portion of the top plate 117 by, for example, a printing layer. A substrate 118 is disposed on the lower surface portion of the top plate 117.

The substrate 118 includes an electrode substrate 119 and a control circuit substrate 120. The electrode substrate 119 is attached to the lower surface of the front end portion of the top plate 117 so as to be held by a frame-like lower frame 143. The lower frame 143 is fixed to the top plate 117 by, for example, adhesion. The electrode substrate 119 has a detection electrode 119a formed on the upper surface thereof so as to face the touch input portion 117s by a conductor pattern.
a is electrically connected to the board-to-board type connector 122 through the through hole and the connecting conductor pattern. The control circuit board 120 is connected to the connector 122 and attached in a substantially vertical state.

The control circuit board 120 includes a contact detection circuit. The touch input unit 11
When the user's finger touches 7s, the human body and the detection electrode 119a are electrostatically coupled,
That is, the capacitance changes and a weak current flows, and the contact detection circuit detects this capacitance change and detects a touch input by the user.

A display substrate 124 is attached to the vicinity of the opening front edge of the housing 13 by a substrate holder 124a. A light emitting diode 125 for display is mounted on the display substrate 124. The light emitting diode 125 is dimmed and protected by a diode holder 125a.

In such a configuration, as shown in FIG. 7, a touch input unit 117 s is formed on the upper surface of the top plate 117, and the heating unit 19 is formed by the touch input unit 117 s.
The touch input unit 221A for setting the heating intensity of the left induction heating coil and the single touch input unit 222A are provided on the left side of the front side. A touch input unit 221B for setting the heating intensity of the right induction heating coil and a single touch input unit 222B are provided on the right front side of the heating unit 18.

In the top plate 114, heating intensity display portions 220 </ b> A and 220 </ b> B are formed in front of the heating portions 19 and 18 corresponding to the light emitting diodes 125.

The single touch input unit 222 is a heating input selecting touch input unit, and is used to select an induction heating coil to be used and to turn on / off the power.

The other single touch input unit 222 is a menu setting touch input unit, and is used to set the heating mode by the induction heating coil to a heating mode such as tempura and stew other than “normal heating”.

Further, the heating intensity setting touch input unit 221 can determine the output of the induction heating coil depending on the position where the finger of the human body comes into contact, and can determine a higher output from the left to the right.

Further, the top plate 114 having such a configuration is different from the first embodiment in the configuration of the lower frame 143 and the exterior member 142.

That is, the lower frame 143 is joined to the top plate 117 via an adhesive applied to a part of the upper surface other than the tip of the lower frame 143.

In addition, a waterproof packing 145 that is an elastic body is provided between the lower frame 143 and the top plate 12, and serves as a cushioning material for the top plate 117 and serves to stop water from entering.

The upper end portion of the casing 13 extends in the upward direction as shown in FIG. 6 and is bent outward at a right angle and extends horizontally toward the outer peripheral side of the opening of the top plate 12. 13a
(Corresponding to the case support) is formed. The flange portion 13a does not have to have a continuous shape on the entire circumference. When the cooker body 11 is dropped into the opening, the flange portion 13a
Is configured to be hooked and supported by the periphery of the opening.

With the configuration in which the flange portion 13a is hooked and supported at the periphery of the opening, the cooker main body 11 is supported in an assembled state by dropping without the load being directly applied to the top plate 117.

At this time, the top plate 117 is placed on the flange portion 13a via the lower frame 143, so that the load of the top plate 117 is supported on the upper surface of the top plate 12, and the lower frame 143 described above. The waterproof packing 145 also supports the load.

A gap 117t is provided below the lower frame 143, and the top plate 117 is provided.
Even when an impact is applied from above, the impact is dispersed.

The exterior member 142 shown in the present modification has a substantially U-shaped cross section with the inner side open, and has a shape that fits and surrounds the tip of the lower frame 141. The lower frame 141 is formed by an adhesive. And the top plate 117. In this case, the exterior member 142 is previously attached to the lower frame 141.
After being fitted and attached to the top plate 117, it may be joined to the top plate 117, or the lower frame 141
After the top plate 117 and the top plate 117 are joined and assembled, the exterior member 142 is attached to the lower frame 141.
It may be fitted from the side to the tip of the.

Also in the second embodiment, an inclined intermediate portion 117b connecting the two surfaces is formed between the inclined surface portion 117a and the side surface portion 117c at the outer peripheral end of the top plate 117. Therefore, since the edge which is an angular part can be decreased, the opportunity for a pot bottom to hit the edge of the outer periphery of the top plate 14 can be reduced, and the top plate 14 can be prevented from being chipped or broken.

The top plate 117 is integrated with the lower frame 143, and the waterproof packing 14 is an elastic body.
5 and the top plate 12 through the flange portion 13a.
Even if the pan is dropped on the 17 inclined surfaces 117a and the bottom of the pan hits the inclined surface 117a, the impact is relieved, so that the top plate 117 can be prevented from being broken or cracked. Furthermore, the inclined surface portion 117
Between the a and the side surface portion 117c, the inclined intermediate portion 11 is located between the two surfaces and connects the two surfaces.
Since 7b is formed and the corners (edges) of the top plate 117 are reduced, chipping and cracking can be further effectively prevented.

In addition, with such a configuration, even if the touch input type (capacitance type) touch input unit 117s for inputting by pressing the top plate 117 by the user is formed, it is elastic with respect to the force pressed by the user from above. Since it can disperse | distribute with a body etc., a top plate can be protected more effectively.

Further, since the exterior member 142 has a substantially U-shaped cross section with the inner side open, and has a shape that fits and surrounds the tip of the lower frame 141, the exterior member 142 is resistant to impact on the outer peripheral inclined surface of the top plate 117. And the lower frame 141 can absorb the impact, and the waterproof packing 145 that is an elastic body is installed on the inner side thereof, so that the impact can be further absorbed on the inner side. It is possible to prevent cracking and chipping of the top plate.

The top plate has an inclined portion that is inclined toward the outer peripheral side surface portion, and the configuration having the inclined intermediate portion that connects the inclined portion and the side surface portion may be on at least one side surface of the outer periphery.
