Description

  The present invention relates to a cooking device provided with an operation unit on a top plate.

  2. Description of the Related Art Conventionally, a gas stove (heating cooker) is known in which a ventilation path is provided on the back side of a glass top plate provided with an operation unit, and cooling air is passed through the ventilation path with a blower to prevent the operation unit from becoming high temperature. (For example, refer to Patent Document 1).

JP 2008-89229 A

  In the conventional one, since the operation section provided on the back of the top plate is provided with a ventilation path and a blower to prevent the temperature from becoming high, the structure of the heating cooker is complicated, the production efficiency is low and the manufacturing cost is low. There is a problem that becomes high. In addition, the gas stove that is operated by a dry cell is generally used, and it is difficult to provide a cooling fan because of insufficient power.

  An object of this invention is to provide the heating cooker which can prevent that the operation part provided in the top plate became high temperature without using an air blower in view of the above point.

  [1] The present invention includes a top plate and a cooker body having a heating unit for heating an object to be heated placed on the top plate, and an operation for operating the heating unit at a front end portion of the top plate. In the heating cooker provided with a portion, on the inner surface of the top plate, the left and right side edges of the top plate are positioned between the heating unit and the operation unit and adjacent to the operation unit. The heat dissipating member for the operation part made of aluminum or copper extending toward the surface is provided in direct contact.

  The front end of the top plate provided with the operation unit tends to be relatively hot at the part closer to the heating part due to radiant heat from the pan or the like and heat transfer from the heating part, and conversely, the part far from the heating part becomes hot. hard. For this reason, unevenness of heat distribution tends to occur at the front end portion of the top plate. When unevenness of heat distribution occurs at the front end portion of the top plate, a part of the front end portion of the top plate becomes high temperature, which may cause the operation unit to break down.

  According to the present invention, the heat of the operation portion heat dissipation member can absorb the heat of the high temperature portion of the front end portion of the top plate and can disperse the heat to the low temperature portion of the operation portion heat dissipation member. As a result, the heat distribution at the front end of the top plate can be made uniform, and it is provided on the top plate with a simple structure as compared with the conventional one using a ventilation path or a blower for cooling the operation unit. It is possible to prevent the operation unit from becoming hot and failing.

  In addition, since the heat radiating member for the operation unit is in direct contact with the inner surface of the front end of the top plate without interposing any inclusions, the heat radiating member for the operation unit efficiently absorbs and dissipates the heat of the front end of the top plate. be able to.

  [2] In the present invention, the top plate includes a rectangular top plate body and a metal frame that covers the periphery of the top plate body, and the operation unit has a front frame that covers the front edge of the top plate body. The front frame part is composed of an inclined part that inclines upward from the front end edge toward the rear, and a rear end part that extends from the rear end of the inclined part toward the top plate body, and the operation part is inclined. In the heating cooker provided in the part, the effect can be exhibited particularly by directly attaching the heat radiating member for the operation part to the inner surface of the rear end part of the front frame part.

  If the operation part is provided on the inclined part of the front frame part, the operation part is inclined to the user side, the operability of the operation part is improved, and compared with the case where the front frame part is formed flat. The area of the operation unit can be increased.

  On the other hand, since the inclined portion is inclined upward from the front edge of the front frame portion toward the rear, the front frame portion is positioned above the outer surface (upper surface) of the top plate body, and the front frame portion Compared with the case where the substrate is formed flat, it becomes more susceptible to radiant heat and the like, the unevenness of the heat distribution is more likely to occur, and the operation unit is likely to become high temperature and easily break down.

  However, according to the above-described configuration of the present invention, the heat distribution of the operation part can be made uniform by the heat radiation member for operation part that is in close contact with the inner surface of the rear end part of the front frame part. In addition, it is possible to prevent the operation unit from being damaged due to a high temperature.

  [3] In the present invention, the rear end portion of the front frame portion is preferably inclined downward from the rear end of the inclined portion toward the rear. According to this, compared with the case where the rear end portion of the front frame portion is formed vertically, the contact area between the rear end portion of the front frame portion and the heat radiation member for the operation portion can be increased. The heat dissipation member can more easily absorb heat from the rear end portion of the front frame portion, and the heat distribution can be made more uniform, which reliably prevents the occurrence of a relatively high temperature portion in the front frame portion of the frame body. can do.

  [4] In the present invention, the operating frame heat dissipating member is fixed to the inner surface of the inclined portion of the front frame portion by a fixing member having a pressing piece portion extending along the inner surface of the rear end portion of the front frame portion. It is preferable to press and fix to the inner surface of the rear end portion.

  As a method of fixing the heat radiating member for the operation portion to the inner surface of the inclined portion of the front frame portion, a method using an adhesive such as silicone, a method of fixing by welding, and the like are also conceivable. However, if it fixes with an adhesive agent, an adhesive agent will interpose between the heat radiating member for operation parts, and a frame, and the heat absorption property of the heat radiating member for operation parts from a frame will be impaired. Moreover, when fixed by welding, there is a possibility that a welding mark may remain on the frame body, and the appearance is impaired.

  As described above, if the fixing member is used for fixing, the frame body and the operating portion heat radiation member can be directly brought into close contact with each other without sandwiching an inclusion such as an adhesive. Compared with the case where a heat radiating member is fixed, the thermal conductivity from a frame to the heat radiating member for operation parts can be improved. Further, it is possible to prevent welding marks from remaining as in the case of welding and to prevent the appearance from being damaged.

  [5] In the present invention, it is preferable that the heat radiating member for the operation unit is brought into contact with a main body side heat radiating member provided on the cooker main body side. According to this, the heat of the heat radiating member for operation part is transmitted to the main body side heat radiating member, and the area of the heat radiating member increases comprehensively, so that the heat radiating effect can be improved.

  In addition, although it is conceivable that the main body side heat radiating member is integrally formed with the operating portion heat radiating member, the present invention is applied to a drop-in type stove or the like installed in a countertop of a system kitchen as a heating cooker. In such a case, the portion of the heat dissipating member for the operating portion that extends into the cooker body may become an obstacle, making it difficult to install and assemble the countertop or the like.

  According to the present invention, since the heat radiating member for operation part and the main body side heat radiating member are only in contact, when the top plate and the cooker main body are separated, the heat radiating member for operation part and the main body side are separated. The heat dissipation member is also separated. Therefore, even when the present invention is applied to a drop-in stove that is dropped into a countertop of a system kitchen as a heating cooker, it can be easily installed and assembled to the countertop.

  [6] In the present invention, when the heating cooker is applied to a gas stove including a gas burner as a heating unit, the main body side heat dissipating member is the primary air or secondary air for the gas burner in the cooker main body. It is preferable to arrange at a location where the water flows.

  In the case of a gas stove, an air supply port or a gap for taking in air for primary air or secondary air is provided, and the gas burner uses air taken in from the air supply port or the gap as primary air or secondary air. If the main body side heat dissipating member is installed at a location where the air flows using this air flow, the heat dissipating effect of both heat dissipating members can be further enhanced.

  [7] In the present invention, it is preferable that a plurality of through holes through which primary air or secondary air passes are provided in the main body side heat dissipation member. If the main body side heat dissipating member is arranged so as to inhibit the flow of air in the cooker main body, the air taken into the cooker main body flows so as to bypass the main body side heat dissipating member, and the main body side heat dissipating member May be difficult to be cooled by the air taken in.

  As described above, if a plurality of through holes are provided in the main body side heat radiating member, air flows so as to directly hit the main body side heat radiating member, and as a result, the contact area between the main body side heat radiating member and the introduced air is increased. In addition, the heat dissipation effect can be enhanced.

The perspective view which shows the heating cooker of embodiment of this invention. Sectional drawing which expands and shows the state which cut | disconnected the heating cooker of FIG. 1 by the II-II line.

  With reference to FIG.1 and FIG.2, the gas stove which is a heating cooker of embodiment of this invention is demonstrated. FIG. 1 shows a drop-in type gas stove installed so as to drop into a counter top A (see FIG. 2) of the system kitchen. In the figure, 1 indicates an enamel top plate, and 2 indicates a stove body (cooker body). The gas stove includes two left and right stove burners 3 (heating units) and a grill 4. The grill burners (not shown) provided on both the stove burners 3 and 3 and the grill 4 are constituted by gas burners.

  The enamel top plate 1 includes a rectangular enamel top plate main body 11 and a stainless steel frame 12 provided on the peripheral edge of the top plate main body 11. Further, an opening (not shown) is formed in the enamel top plate 1, and a stove burner 3 as a heating portion projects upward from the opening (not shown).

  The stove burner 3 includes a mixing tube 31 provided in the stove main body 2 whose upper surface opening is covered with the enamel top plate 1. A burner body 32 protruding upward from an opening (not shown) of the enamel top plate 1 is provided at the downstream end of the mixing tube 31. A burner head 33 is placed on the burner body 32.

  A gas nozzle 34 facing the upstream end of the mixing tube 31 is provided in the stove body 2. A mixed gas (air mixture) of the fuel gas ejected from the gas nozzle 34 and the primary air sucked from the upstream end of the mixing pipe 31 is generated in the mixing pipe 31.

  A large number of teeth are suspended from the outer periphery of the lower surface of the burner head 33, and a flame hole is formed in the gap between these teeth. The air-fuel mixture from the mixing tube 31 is ejected from the flame hole through the burner body 32. And the to-be-heated material mounted on the enamel top plate 1 through the five virtues 5 is heated by the flame produced | generated by combustion of the air-fuel mixture which ejected.

  The front frame portion 13 positioned forward among the four sides of the frame body 12 is configured to be wider than the horizontal frame portions 14 and 14 positioned on the left and right. An exhaust port 15 a for exhausting combustion gas in the grill 4 is provided in the rear frame portion 15 located on the rear side of the four sides of the frame body 12.

  The front frame portion 13 includes an inclined portion 13a that is inclined upward from the front end edge toward the rear, and a rear end portion 13b that is inclined downward from the rear end of the inclined portion 13a toward the rear. The inclined portion 13a is provided with a sheet-like operation portion 6 for operating ignition / extinguishing of the burner burner of the stove burner 3 and the grill 4 and the amount of combustion.

  An operation portion heat radiation member 71 made of plate-like aluminum or copper is in direct contact with the inner surface (lower surface) of the rear end portion 13b. The operating portion heat radiating member 71 extends in the left-right direction as much as the left-right width of the top plate body 11, and the front end of the operating portion heat radiating member 71 extends to the rear portion of the inclined portion 13a. Adjacent on the rear side, the operating portion heat radiation member 71 is formed in a substantially L-shaped cross section along the inner surface of the rear end portion 13b so as to be in close contact with the rear end portion 13b. A drooping portion 71 a that hangs downward is formed at the rear end of the operating portion heat radiation member 71.

  The front frame portion 13 is likely to reach a relatively high temperature due to radiant heat from a pan or the like and heat transfer from the flame of the stove burner 3 as the portion closer to the stove burner 3. The temperature of the portion becomes the highest and unevenness of the heat distribution in the front frame portion 13 is likely to occur.

  However, in the gas stove according to the embodiment, as described above, the operating portion heat radiation member 71 extends in the left-right direction to the inner surface (lower surface) of the rear end portion 13b of the front frame portion 13 as much as the left-right width of the top plate body 11. Since the heat radiating member 71 for operation part with high heat conductivity absorbs the heat of the rear end part 13b of the front frame part 13 and disperses the absorbed heat in the left-right direction, the heat distribution is made uniform. Therefore, it is possible to prevent a part of the front frame portion 13 from having a relatively high temperature due to uneven heat distribution.

  Therefore, according to the gas stove of the embodiment, it is possible to prevent the operation unit 6 provided on the enamel top plate 1 with a simple structure from becoming high temperature without using a ventilation path or a blower for cooling the operation unit as in the past. can do.

  Further, the front frame portion 13 is provided with a rear end portion 13b inclined upward from the top plate body 11 side, and the operating portion heat radiation member 71 is in close contact with the rear end portion 13b. Compared with the case where 13 is made flat, the contact area between the rear end portion 13b and the operating portion heat radiation member 71 can be increased. Thereby, the heat radiating member 71 for operation part can make it easier to absorb the heat | fever of the front frame part 13. FIG.

  Further, since the operation unit 6 is provided in the inclined portion 13a that is inclined relatively gently downward toward the front, when the user operates the operation unit 6, the operation unit is directed toward the front which is the user side. As a result, the operability and visibility of the operation unit 6 are improved.

  On the inner surface (lower surface) of the inclined portion 13a, a fixing member 8 having a presser piece portion 8a extending toward the rear end portion 13b is fixed by welding, adhesion, or the like. The operating portion heat radiation member 71 is pressed and fixed by the pressing piece portion 8a of the fixing member 8 so as to be in direct contact with the inner surface (lower surface) of the rear end portion 13b.

  In this way, by fixing the operating portion heat radiating member 71 to the front frame portion 13 by the fixing member 8, the operating portion heat radiating member 71 and the front frame portion 13 are directly in close contact with each other without sandwiching an inclusion such as an adhesive. Thus, the heat absorption efficiency from the front frame portion 13 of the operating portion heat radiation member 71 can be improved.

  Further, if the operating portion heat radiation member 71 is welded and fixed to the front frame portion 13, welding marks may remain and the appearance of the frame body 12 may be impaired. However, like the gas stove of the embodiment, the fixing member 8 may be used to operate the operating portion. By fixing the heat radiating member 71 to the front frame portion 13, it is possible to prevent the appearance of the frame body 12 from being damaged without generating welding marks.

  In addition, when the fixing member 8 is fixed to the inclined portion 13a by welding, if spot welding is performed at a portion that can be covered with the panel sheet of the operation unit 6 disposed on the upper surface of the inclined portion 13a, the welding trace remains temporarily. Also, the welding marks can be covered with the panel sheet of the operation unit 6, and the appearance of the gas stove can be kept good.

  Further, in addition to fixing by the fixing member 8, the operation part heat radiating member 71 may be fixed by adhesion with a caulking material such as silicone so that the operation member heat radiating member 71 does not shift in the horizontal direction with respect to the frame 12. In this case, when the caulking material enters between the operation portion heat radiation member 71 and the front frame portion 13 or a gap is generated between the operation portion heat radiation member 71 and the front frame portion 13, the operation portion heat radiation member 71. Since the endothermic property from the front frame portion 13 is reduced, care must be taken.

  The hanging portion 71a of the operating portion heat radiation member 71 is in contact with the upper end portion of a plate-like aluminum or copper main body side heat radiation member 72 provided on the stove main body 2 side. Thereby, the heat of the heat radiating member 71 for operation part is transmitted to the main body side heat radiating member 72, and the area of the whole heat radiating members 71 and 72 is increased, whereby the heat radiating effect can be improved.

  Further, the upper end portion of the main body side heat radiating member 72 is slightly tilted forward, and when contacting the operating portion heat radiating member 71, it comes into contact with the back in an elastically curved manner. Accordingly, it is possible to prevent the operation portion heat radiation member 71 and the main body side heat radiation member 72 from being brought into contact with each other due to an assembly error or the like, and to reliably bring them into contact with each other.

  The main body side heat radiating member 72 is disposed at a portion where primary air or secondary air taken in from the gap B between the countertop A of the system kitchen on the front side of the stove main body 2 flows. Thereby, the main body side heat radiation member 72 is cooled by the flow of air for primary air or secondary air, and the heat radiation effect can be further enhanced.

  The primary air is air that is sucked into the mixing tube 31 by the fuel gas ejected from the gas nozzle 34 into the mixing tube 31. Further, the secondary air passes through the space at the central portion where the burner body 32 provided at the upstream end of the mixing pipe 31 and the pan bottom temperature sensor 9 (see FIG. 1) of the burner head 33 are disposed. Air that is sucked from the inside of the stove main body 2 by a natural draft accompanying combustion and used for the combustion of the stove burner 3.

  The main body side heat radiating member 72 is provided with a plurality of through holes 72a, and the air for primary air or secondary air passes through the through holes 72a. According to this, air flows so as to directly hit the main body side heat radiating member 72 without flowing so as to bypass the main body side heat radiating member 72. Therefore, the contact area between the main body side heat radiating member 72 and the air taken into the stove main body 2 from the gap B can be increased, and the heat radiating effect of both the heat radiating members 71 and 72 can be further enhanced.

  In the embodiment, the top plate body 11 is made of enamel and the frame body 12 is made of stainless steel. However, the present invention is not limited to this, and aluminum or copper heat radiating members 71 and 72 are made of the frame body. If the heat of 12 front frame parts 13 can be absorbed, the top-plate main body 11 and the frame 12 may be comprised with another material.

  In the embodiment, the operation unit 6 is provided on the front frame portion 13 of the frame body 12. However, the operation unit 6 may be provided on the top plate body 11. In this case, the heat dissipating member 71 for the operation unit may be directly adhered to the inner surface (lower surface) of the top plate main body 11 so as to be adjacent to the control unit 6 on the side of the combustor 3, and the frame body 12 may not be provided. .

  In the embodiment, the stove burner 3 (gas burner) is used as the heating unit. However, the heating unit is not limited to this. For example, the heating unit may be one that heats an object to be heated by electromagnetic induction. An effect can be obtained.

  Further, in the embodiment, the rear end portion 13b of the front frame portion 13 is inclined downward from the rear end of the inclined portion 13a toward the rear, but the shape of the rear end portion 13b is not limited to this, for example, Even if the rear end portion 13b is formed vertically, the effect of the present invention can be obtained.
