Description

  The present invention relates to an operation display device that displays a light source when a start operation of a heat source or a heating amount adjustment operation is performed by an operation element that operates a heat source of a heating cooker.

  Conventionally, as this type of operation display device, a ring member formed of a translucent material surrounding an operation element for operating a heat source of a heating cooker, and a light source for operation display that is turned on when the heat source is operated, the light source It has been known that the heat source is displayed by irradiating light from a ring member through a ring member (for example, see Patent Document 1). In this case, a plurality of heating amount display light sources that are sequentially turned on according to the heating amount of the heat source are prepared, and the heating amount display light is displayed in a plurality of window holes formed at positions away from the ring member of the operation panel. Each light source is exposed so that the heating amount can be displayed.

By the way, as in the conventional example described above, if the operation panel is provided with a window hole that faces the light source for displaying the heating amount separately from the ring member, the operation panel becomes complicated and the appearance is impaired. In this case, if the light source for displaying the heating amount is arranged facing the ring member for operation display, and the light from the light source is irradiated through the ring member, the display space is concentrated on the ring member. Thus, it is not necessary to separately form a display portion (window hole) for displaying the heating amount on the operation panel, and the operation panel is neat and the appearance is improved. However, in this case, the light from the light source for displaying the heating amount diffuses in the ring member, and the heating amount display becomes blurred and difficult to identify.

  In view of the above, the present invention consolidates the display space by irradiating light from the light source for heating amount through the ring member that irradiates light from the light source for operation display, and displays the heating amount. It is an object of the present invention to provide an operation display device for a heating cooker that can clarify the above.

In order to solve the above problems, the present invention includes a ring member formed of a translucent material that surrounds an operation element that operates a heat source of a heating cooker, and a light source for operation display that is lit when the heat source is activated, In the operation display device of the cooking device adapted to irradiate light from this light source through the ring member, comprising a plurality of heating amount display light sources that are sequentially turned on according to the heating amount of the heat source, A plurality of light guide members are fitted into the ring member at intervals in the circumferential direction, each light guide member has an output part facing the axial direction of the ring member, and the output part is each light guide member of the ring body Is brought into surface contact with the portion into which the light is inserted, and light from each light source for displaying the heating amount is irradiated through each light guide member.

  According to the present invention, the light from the light source for heating amount display is guided into the ring member without being diffused by the light guide member, and the tip of the light guide member shines brightly. Therefore, it becomes possible to clearly separate and visually recognize the light from each light source for heating amount display, and the heating amount display is clarified.

  By the way, the emitting part on the front end side of the light guide member needs to be directed toward the axial direction of the ring member so that light is irradiated to the axial direction of the ring member. In this case, it is possible to form the light guide member in a straight shape extending in the axial direction of the ring member. However, in this case, the arrangement pitch of the emitting portions of the plurality of light guide members and the tail ends of these light guide members In order to avoid interference between the light sources, the arrangement pitch of the light emitting units can be narrowed to a predetermined limit or less in order to avoid the interference between the light sources. Disappear.

  On the other hand, the light guide member is formed in a substantially L shape having an emission part that faces the axial direction of the ring member and an incidence part that is bent with respect to the emission part and extends radially outward of the ring member. In this case, even if the arrangement pitch of the light emitting portions of the plurality of light guide members is narrow, the arrangement pitch of the outer end of the incident portion, that is, the arrangement pitch of the light source for displaying the heating amount facing the outer end of the incident portion is secured widely. Is done. Therefore, the degree of freedom of design regarding the arrangement pitch of the emitting portions can be increased.

  FIG. 1 shows a cooking device comprising a drop-in type gas stove incorporated in a countertop CT (see FIG. 2) of a system kitchen. The stove includes a box-shaped stove body 1 having an upper surface as an open surface. As shown in FIG. 2, an outer bending flange 1a is formed on the upper edge of the stove body 1, and the outer bending flange 1a is inserted into the stove opening CTa opened in the countertop CT. The stove body 1 is suspended from the countertop CT by being hooked to the opening edge of the opening CTa. The stove body 1 is covered from above with the top plate 2 placed on the countertop CT over the outer bending flange 1a.

  The stove body 1 is provided with a total of three stove burners 3 and a grill 4, two on the left and right on the front side and one on the rear side as heat sources. Then, the top plate 2 is formed with openings for allowing the respective conburners 3 to face, and the five virtues 5 are placed so as to surround the respective openings, and the exhaust port 2a for the grill 4 is provided at the rear portion of the top plate 2. Forming. Each cooker 3 is provided with a pan bottom temperature sensor 3a that is positioned in the inner peripheral space and abuts against the bottom surface of the cooking container on the virtues 5 to detect its temperature. The gas supply to each stove burner 3 and the gas supply to a grill burner (not shown) provided in the grill 4 are controlled by each electric valve 6 provided in the stove body 1. A controller 7 for controlling 6 is disposed at the bottom of the stove body 1.

  The front portion of the stove body 1 is under the counter top CT portion on the front side of the stove opening CTa, and the grill door 4a is exposed to the front of the front portion under the counter top CT. The left and right operation panels 8L and 8R are provided. Further, end pieces 9 are attached to the left and right outer surfaces of the stove body 1 to seal gaps formed between the left and right side surfaces of the stove installation space secured under the countertop CT from the front.

  The grill door 4a is biased to the left from the horizontal center of the stove body 1, and the right operation panel 8R has a longer horizontal length than the left operation panel 8L. Then, on the right operation panel 8R, the three operation elements 10B for the three control burners 3 are arranged side by side in the horizontal direction, and the heating by each of the control burners 3 is arranged below the arrangement part of the operation elements 10B. A drawer type control panel 11B having various operation switches for setting a mode, a heating temperature, and the like and a display unit is arranged, and further, a power switch 12 is arranged at the upper right corner. Further, on the left operation panel 8L, an operator 10G for the grill 4 and a pull-out grill 4 control panel 11G on the lower side thereof are arranged.

  The operation panels 8L and 8R are connected to the front surface of the support frame 13 that supports the operation elements 10B and 10G, respectively. This point will be described in detail with reference to FIGS. 3 and 4 for the support frame 13 that supports the right operation panel 8R and the operation element 10B for the stove burner 3. FIG. The support frame 13 includes a resin box 131 that opens to the rear, and a lid plate 132 that is attached to the opening surface of the rear end of the box 131. Each operation for the control burner 3 is performed on the lid plate 132. The child 10B is supported. Here, on the front surface of the box 131, a pair of upper and lower male engaging portions 133, 133 formed by flange portions projecting up and down are formed. Further, the operation panel 8R is formed of an extrusion molding material of metal, for example, aluminum in order to give a high-class feeling. On the back side of the operation panel 8R, a pair of upper and lower female engaging portions 81, 81 extending in the lateral direction with a groove-like cross-sectional shape corresponding to the male engaging portion 133 is formed at the time of extrusion molding. The Then, the female mold engaging portions 81 and 81 of the operation panel 8R are slid and engaged with the male mold engaging portions 133 and 133 of the support frame 13 in the lateral direction, whereby the operation panel 8R is mounted on the front surface of the support frame 13. It is connected. According to this, the connecting portion between the support frame 13 and the operation panel 8R does not appear on the appearance, the appearance is good, and unlike the case where the operation panel is adhered to the front surface of the support frame 13, the assembly is facilitated. It is also possible to form a male engaging portion on the operation panel 8R and slide it into a female engaging portion formed on the support frame 13 from the lateral direction.

  By the way, the operation panel 8 </ b> R cannot be positioned in the lateral direction with respect to the support frame 13 only by engaging the male and female engaging portions 133 and 81. Therefore, the ring member 14 surrounding each operation element 10B is attached to the support frame 13, and the ring member 14 is fitted into the operation element opening 82 that faces each operation element 10B formed on the operation panel 8R. . According to this, the operation panel 8 </ b> R is positioned in the lateral direction with respect to the support frame 13 via the ring member 14. Then, the operation element 10B is centered with respect to the operation element opening 82 via the ring member 14, and the operation element 10B can be reliably prevented from being eccentric with respect to the operation element opening 82 and losing appearance.

  Here, the ring member 14 is formed in a stepped shape having a rear-side large-diameter portion 141 and a front-side small-diameter portion 142, and is formed in a ring mounting hole 134 formed on the front surface of the box 131 constituting the support frame 13. The large diameter portion 141 is detachably mounted from the rear. After connecting the operation panel 8R to the front surface of the support frame 13, the ring member 14 is mounted in the ring mounting hole 134 so that the front end surface of the large diameter portion 141 is in contact with the back surface of the operation panel 8R. The small-diameter portion 142 is fitted into the operator opening 82 of the operation panel 8R.

  The lower part of the operation panel 8R is recessed rearward with respect to the upper part joined to the front surface of the support frame 13, and the storage box 111 (FIG. 2) of the control panel 11B is pressed into the recessed part 83 by pressing after extrusion. An opening 84 for mounting a reference) is formed. The control panel 11B is pushed forward by a push-push mechanism (not shown) incorporated in the storage box 111 and then pushed forward of the storage box 111, and the operation surface on the upper surface of the control panel 11B protrudes forward of the operation panel 8R. To do. The advancing / retreating direction of the control panel 11B is set to a direction inclined forward and downward. According to this, in the projecting state of the control panel 11B, it is possible to push various switches on the operation surface while viewing the operation surface from obliquely above, and the operability is improved. Smooth movement of the panel 11B can be obtained. In addition, a cover plate 112 with an aluminum plate attached to the outer surface is attached to the front end of the control panel 11B. When the control panel 11B is stored, the cover plate 112 is flush with the upper portion of the operation panel 8R. The recessed portion 83 is covered and concealed, and the appearance is kept good.

  On the upper edge of the operation panel 8R, a flange portion 85 is formed projecting behind the upper female engagement portion 81, and an engagement claw 86 for the stove body 1 is formed on the rear edge of the flange portion 85 by punching. ing. In addition, attachment holes 87 for the stove body 1 are formed in the left and right sides of the recessed portion 83 of the operation panel 8R. Then, in a state where the engaging claw 86 is engaged with an engaging hole (not shown) formed on the upper front edge of the front portion of the stove body 1, the operation panel 8 </ b> R is attached to the front portion of the stove body 1 in the mounting hole 87. It is screwed to the front.

  As shown in FIG. 3, each operation element 10 </ b> B has a cylindrical shape in which an aluminum cap 101 is fitted on the outer surface, and a relay in which a push-push mechanism is incorporated in the rotary encoder 102 fixed to the cover plate 132 of the support frame 13. They are connected via the member 103. Further, the limit switch 104 is fixed to the lid plate 132 by being positioned on the side of the rotary encoder 102, and a diameter-enlarged portion 105 that cooperates with the limit switch 104 is provided at the rear end portion of the operation element 10B. The operating element 10B is normally in the rear immersing position, and once pushed in from the immersing position, it moves forward to the forward protruding position by the push-push mechanism. When the forward movement of the operating element 10B to the protruding position is detected by the limit switch 104, the corresponding burner 3 is ignited, and further, a signal from the rotary encoder 102 is generated by the rotation operation of the operating element 10B at the protruding position. Is transmitted to the controller 7, and the electric valve 6 is controlled to adjust the heating power of the stove burner 3.

  In the box 131 of the support frame 13, a display substrate 15 that also serves as a pressing plate for pressing the three ring members 14 corresponding to the three operating elements 10B from the rear is attached. As shown in FIG. 5, the display substrate 15 is positioned below each ring member 14 and is lit when the burner 3 corresponding to the operation element 10 </ b> B surrounded by the ring member 14 is burned (during operation). A light source 15S for operation display composed of LEDs to be mounted is attached, and is positioned on the upper side of each ring member 14, and is sequentially turned on in accordance with the heating power (heating amount) of the corresponding burner 3 The light source 15K is attached. The heating amount display light source 15K is configured by an LED that emits light of a color different from that of the operation display light source 15S. In addition, a power switch 12 is attached to the upper right corner of the display substrate 15, and an LED (not shown) is incorporated in the power switch 12 so that the power switch 12 lights up when the power is turned on.

  Each ring member 14 is formed of a translucent material. Then, as shown in FIG. 3, a recessed portion 143 is formed in a portion of each ring member 14 facing the operation display light source 15S, and the light from the operation display light source 15S is recessed. Is incident on the ring member 14, is reflected and diffused in the ring member 14, and is irradiated forward from the entire circumferential direction of the small diameter portion 142. Thus, at the time of combustion of each combustor 3, the ring member 14 surrounding the corresponding operation element 10 </ b> B shines. Therefore, whether or not the corresponding conburner 3 is burning is determined by whether or not the ring member 14 is lit. It can be clearly identified.

  A plurality of light guide members 144 are fitted on the upper portions of the ring members 14 at intervals in the circumferential direction, and light from the light sources 15K for displaying the heating amount is irradiated through the light guide members 144. I am doing so. Here, it is possible to arrange each light source 15K for displaying the heating amount behind the ring member 14 so that light from each light source 15K enters the ring member 14 without passing through the light guide member. Light diffuses and the heating amount display is blurred and difficult to identify. On the other hand, according to the present embodiment, the light from the heating amount display light source 15K is guided into the ring member 14 without being diffused by the light guide member 144, and the tip of the light guide member 144 shines brightly. Therefore, the light from each light source 15K for displaying the heating amount can be clearly separated and visually recognized, and the heating amount display is clarified.

Each light guide member 144 has a light emitting portion 144a facing forward in the axial direction of the ring member 14, that is, a front portion, and an incident portion 144b that is bent with respect to the light emitting portion 144a and extends radially outward of the ring member 14. It is formed in an L shape. Then, a plurality of radial grooves 145 are formed on the upper rear surface of the ring member 14, the light guide members 144 are fitted into the grooves 145 from the rear, and the emission portions 144a of the light guide members 144 are clearly shown in FIG. The light guide members 144 of the ring member 14 are brought into surface contact with the portions where the light guide members 144 are fitted, and the outer ends of the incident portions 144b of the light guide members 144 are opposed to the light sources 15K for displaying the heating amount. Here, it is conceivable to form the light guide member 144 in a straight shape extending in the axial direction (front-rear direction) of the ring member 14 from the emission portion 144a. However, in this case, the emission portions 144a of the plurality of light guide members 144 are formed. In order to avoid interference between the light sources, the arrangement pitch must be equal to the arrangement pitch of the light sources for displaying a plurality of heating amounts facing the incident part on the tail end side of the light guide member 144. It becomes impossible to narrow the arrangement pitch of 144a below a predetermined limit. On the other hand, in this embodiment, even if the arrangement pitch of the output portions 144a of the plurality of light guide members 144 is narrow, the arrangement pitch of the outer ends of the incident portions 144b, that is, the heating amount that faces the outer ends of the incident portions 144b. A wide arrangement pitch of the display light sources 15K is ensured. Therefore, the degree of freedom of design regarding the arrangement pitch of the emitting portions 144a can be increased.

  The light guide member 144 may be a light guide tube that guides light by internal reflection, but in the present embodiment, the light guide member 144 is formed of a translucent material. Then, an inclined reflecting surface 144c is formed at a bent portion between the emitting portion 144a and the incident portion 144b so that light from the incident portion 144b is totally reflected by the reflecting surface 144c and guided to the emitting portion 144a. . Moreover, in this embodiment, although the light guide member 144 is formed in L shape of uniform thickness, you may make the diameter of the outer end side of the incident part 144b thick. According to this, the light from the light source 15K is easily captured, and even if there is some variation in the mounting position of the light source 15K, the light from the light source 15K is reliably incident on the light guide member 144, and the mounting of the light source 15K is performed. This is effective as a countermeasure for positional variations.

  With reference to FIG. 1, a plurality of vent holes 16 for taking combustion air into the stove body 1 are formed in the upper front surface of the stove body 1 located in the stove opening CTa of the countertop CT. When the stove burner 3 or the grill burner burns, the suction of the primary air into the burner mixing tube 3b or the suction of secondary air by the draft of the combustion flame causes the inside of the stove body 1 to become negative pressure, and air is sucked from the vent hole 16. The air flow toward the burner mixing pipe 3b and the burner combustion section is generated. Further, the counter top CT is cooled by the air sucked toward the vent hole 16.

  By the way, the inside of the stove body 1 becomes considerably high due to the radiant heat from the stove burner 3 and the grill 4, and it is necessary to cool the electric valve 6 in order to prevent the heat loss of the electric valve 6. Here, the air flowing in from the vent hole 16 flows to the upper part in the stove body 1, and the electric valve 6 disposed in the lower part in the stove body 1 cannot be cooled by the inflow air from the vent hole 16. In this case, it may be possible to open an air intake port for cooling the electric valve 6 in the operation panel 8R located in front of the arrangement portion of the electric valve 6, but in this case, the operation panel 8R is formed of an extrusion molding material. By doing so, the flat feeling that is about to be obtained is impaired, and the appearance is deteriorated.

  Therefore, in this embodiment, as clearly shown in FIGS. 3 and 6, an air intake port 17 for cooling the electric valve 6 is opened on the front upper surface 1 b of the stove body 1 facing the lower surface of the countertop CT. ing. In addition, in order to prevent the boiled juice falling from the inner space of the stove burner 3 from being applied to the electric valve 6, a boiled cover 18 is provided in the stove body 1 to cover the arrangement portion of the electric valve 6 from above. The front end portion of the boiling cover 18 is overlapped with the rear end portion of the front upper surface 1b of the stove body 1, so that the boiling cover 18 is continuous with the rear end portion of the front upper surface 1b of the stove body 1. . According to this, even if the burner mixing pipe 3b is arranged above the arrangement part of the electric valve 6, an air flow from the air intake port 17 toward the burner mixing pipe 3b through the lower space of the cover 18 is formed. The electric valve 6 is reliably cooled by this air flow.

  However, on the front upper surface 1b of the stove body 1, boiled juice that has flowed out of the top plate 2 may hang down along the lower surface of the countertop CT, and as it is, it is formed on the front upper surface 1b of the stove body 1. There is a possibility that the simmered juice enters the stove body from the air intake port 17. Therefore, a cover plate 171 is provided on the front upper surface 1b of the stove body 1 so as to cover the upper surface 1b from above over the portion where the air intake port 17 is formed, and the cover plate 171 does not overlap above the air intake port 17. Thus, an air inlet 172 is formed. According to this, a kind of labyrinth-like air passage from the air inlet 172 to the air inlet 17 through the gap between the front upper surface 1b of the stove body 1 and the cover plate 171 is formed. It is effectively prevented that the spilled juice enters 17. Moreover, the formation location of the air inflow port 172 of the cover board 171 has risen upwards, and the penetration | invasion of the boiled juice to the air inflow port 172 is suppressed.

  Further, in the present embodiment, a flange portion 173 that is recessed downward is formed in a portion near the front edge of the front upper surface 1 b of the stove body 1, and the air intake port 17 is located above the bottom surface of the flange portion 173. That is, it is formed in the corner portion at the upper edge of the rising portion on the rear side of the flange portion 173. An air inflow port 172 is formed in a portion of the cover plate 171 that overlaps above the flange portion 173. Therefore, the boiled sap falling from the air inlet 172 enters the bowl 173, and the boiled sap can be reliably prevented from entering the air intake port 17.

  Although the structure of the stove including the operation panel 8R located on the right side of the grill 4 has been described above, the structure of the stove including the operation panel 8L located on the left side of the grill 4 is the same as described above, and the detailed description thereof is omitted. To do.

  In the above embodiment, the present invention is applied to an operation display device for a drop-in gas stove. However, a heating cooker other than a gas stove, for example, an electric stove using an electric heater as a heat source, and further an electromagnetic induction coil as a heat source. The present invention can be similarly applied to an operation display device of an IH cooker to be used.
