Abstract

To provide a stove which can avoid a failure related to a harness of temperature detection means even if the stove has a thin housing.SOLUTION: Since a housing 2 is formed into a thin form with a relatively low vertical height, a lower portion of a harness extending from a lower end part of a pan sensor for detecting a temperature of a heated object tends to come close to or contact with a bottom surface part 25. An inclined surface part 50 is a slope part disposed in a position of the bottom surface part 25 of the housing 2 which corresponds to a position at which a burner body of a stove burner is disposed in a plan view. A recessed part 60 is a recessed part recessed downward relative to the inclined surface part 50 around the inclined surface part 50. Even if a liquid that has entered into an interior of the housing 2 drops on the inclined surface part 50, the liquid flows on an upper surface of the inclined surface part 50 to be guided into the recessed part 60. Thus, the harness which comes close to or contacts with the upper surface of the inclined surface part 50 is less likely to be immersed in the liquid.SELECTED DRAWING: Figure 5

JP 2017-44370 A

  There is a demand for a stove thinner than a general stove without a grill for single persons and the like. Since the pan sensor is provided to extend in the up-down direction, in the case of a thin stove, the lower end side of the harness extending from the pan sensor may come into contact with or approach the bottom of the housing of the stove. In this state, if liquid such as broth enters the inside of the housing due to boiling, etc., the harness will be immersed in the liquid accumulated at the bottom of the housing, causing various problems such as corrosion of the harness. There is a problem that can be.

  The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a stove that can avoid a problem related to a harness of a temperature detecting unit even with a stove having a thin housing. .

  The stove according to claim 1 of the present invention has a housing having an open upper portion, a tubular portion arranged in the housing, for mixing fuel gas and air, and one end of a mixing pipe portion extending in a predetermined direction being a lower portion. A stove burner provided with a burner main body connected to the stove, and a stove provided with a temperature detecting means provided to vertically penetrate the burner main body and detecting a temperature of an object to be heated by the stove burner. A bottom surface of the housing, a surface portion provided at a position corresponding to a position where the burner body of the stove burner is arranged in a plan view, and a slope surface portion inclined downward in a predetermined direction; And a recess formed in the periphery of the surface portion so as to be recessed from the upper surface of the inclined surface portion.

  In the stove according to claim 2, in addition to the configuration according to claim 1, the concave portion is provided around a position other than a highest position of the inclined surface portion, and is connected to a lower end portion of the temperature detecting means. The harness extends from the lower end of the temperature detecting means toward the highest position of the inclined surface.

  A stove according to a third aspect is characterized in that, in addition to the configuration according to the first or second aspect, the concave portion is provided with a hole that vertically passes through the concave portion.

  The stove according to claim 4, in addition to the configuration according to any one of claims 1 to 3, wherein the housing has the stove burners arranged side by side in the left-right direction, and the bottom of the housing has In the plan view, the burner bodies of the two stove burners are each provided with the inclined surface portion at each of the positions where the burner main bodies are arranged, and the concave portions are provided around the respective inclined surface portions. A first extending portion that extends in a concave or convex shape so as to be connected to, and a concave or convex shape extending in the left-right direction from the respective concave portion toward a side opposite to a side on which the first extending portion is provided. A second extending portion, wherein the first extending portion and the second extending portion are arranged at the same position in the front-rear direction.

The stove according to claim 5, in addition to the configuration according to claim 4, wherein the bottom of the housing is
A third extending portion extending in a left-right direction in a concave or convex shape is provided forward or rearward of the first extending portion and the second extending portion.

  In the stove, since the upper end of the temperature detecting means is provided so as to come into contact with an object to be heated such as a pan, the harness connected to the temperature detecting means is generally provided to extend from the lower end of the temperature detecting means. is there. In the case where a thin case is employed, particularly when the object to be heated is being heated by the stove burner, the lower end of the temperature detecting means is close to the bottom of the case, and the harness is close to or close to the bottom of the case. May be in contact. The stove according to claim 1 is provided with an inclined surface portion and a concave portion at a position corresponding to a position where the main body portion of the stove burner is arranged at a bottom portion of the housing. In this case, the lower end side of the harness is easily arranged on the inclined surface. Even if liquid such as broth enters the inside of the housing and drops on the inclined surface, the liquid descends on the upper surface of the inclined surface and is guided to the concave portion, so that it is difficult for the liquid to accumulate on the upper surface of the inclined surface. For this reason, even if the lower end side of the harness is arranged close to or in contact with the inclined surface, the harness is less likely to be immersed in the liquid. Therefore, the stove according to claim 1 can avoid a problem with the harness of the temperature detecting means even if the stove has a thin housing.

  The liquid dropped on the inclined surface is guided to a concave portion provided around a position other than the highest position in the inclined surface. Since the harness of the temperature detecting means extends from the lower end of the temperature detecting means toward the highest position of the inclined surface, the stove according to claim 2 has a harness in addition to the effect of the invention according to claim 1. The liquid can be made harder to adhere to the lower end of the.

  The liquid guided from the inclined surface to the recess is discharged to the outside of the housing through the hole, so that the liquid is less likely to accumulate on the inclined surface and the recess. Therefore, in the stove according to the third aspect, in addition to the effect of the invention according to the first or second aspect, the liquid can be made more difficult to adhere to the lower end portion of the harness.

  When the stove employs a thin case, it is difficult to secure a space for providing a member for reinforcing the case inside the case. The stove according to claim 4 is characterized in that, in addition to the effect of the invention according to any one of claims 1 to 3, the first extension portion and the second extension portion extend through the recess at the bottom of the housing in the left-right direction. Place the part. Therefore, even when a thin housing is employed, the rigidity of the bottom of the housing is improved, and the overall strength of the stove can be maintained.

  The stove according to claim 5 can further improve the strength of the housing in addition to the effect of the invention described in claim 4.

It is a perspective view of the stove 1 from which the top plate 3 and the stove burner 4 on the left side are omitted. FIG. 3 is a perspective view of a housing 2. FIG. 4 is a plan view of a housing 2. FIG. 6 is a cross-sectional view taken along line II of FIG. 5.

  Embodiments of the present invention will be described below. The structure of the device described below is not limited to the description but is merely an illustrative example unless otherwise specified. The drawings are used to explain technical features that can be adopted by the present invention. In the following description, left and right, front and rear, and up and down indicated by arrows in the figure will be used. Note that the stove 1 shown in FIG. 1 is a table stove that is not provided with a grill and is configured to be small and thin for single persons or the like, but may be a built-in stove or the like.

  The stove 1 will be described with reference to FIGS. As shown in FIG. 1, the stove 1 includes a housing 2 and a top plate 3. The housing 2 is formed in a thin, substantially rectangular parallelepiped shape having a right wall portion 21, a left wall portion 22, a front wall portion 23, a rear wall portion 24, and a bottom surface portion 25. The top plate 3 is disposed on the top of the housing 2 so as to cover an opening 26 surrounded by the right wall portion 21, the left wall portion 22, the front wall portion 23, and the rear wall portion 24 of the housing 2. . The top plate 3 has an opening (not shown) through which the two stove burners 4 and 4 are inserted. When the top plate 3 is installed in the opening 26 of the housing 2, the upper portions of the two stove burners 4, 4 pass through the openings, and are lined up in the left-right direction substantially at the center of the top plate 3 in the front-rear direction.

  The stove burner 4 mainly includes a burner main body 40, a burner head 42 (see FIG. 1), and a throat portion 46. The burner main body 40 forms a main body of the stove burner 4. The burner head 42 is mounted on the upper part of the burner main body 40. The throat portion 46 is a hollow tubular portion having a predetermined length in the front-rear direction. The throat portion 46 extends in the front-rear direction while inclining upward from an upstream end 46A, which is a front end, to a downstream end 46B, which is a rear end. The downstream end 46B is connected to a lower portion of the burner main body 40. That is, inside the opening 26, two stove burners 4, 4 are arranged side by side in the left-right direction with the respective throat portions 46 extending in the front-rear direction. At an approximate center of the upstream end 46A, an inlet (not shown) through which fuel gas and air flow is provided. The throat section 46 mixes the fuel gas and the primary air flowing from the inflow port, and converts the air-fuel mixture of the fuel gas and the air from the upstream end 46A, which is the upstream end of the air-fuel mixture, to the downstream side of the air-fuel mixture. It is passed toward the downstream end 46B which is the end. The air-fuel mixture that has flowed into the burner main body 40 from the downstream end portion 46 </ b> B is blown out from a plurality of flame openings formed between the burner main body 40 and the burner head 42.

  An axial ignition electrode 44 for igniting by discharge and an axial thermocouple 45 for detecting the presence or absence of a flame are provided in the vicinity of the flame outlet behind the burner head 42. At the center of the burner head 42, an axial pot sensor 43 extending in the vertical direction is provided so as to pass through the center of the burner head 42 and the center of the burner main body 40. The pot sensor 43 is provided for storing a thermistor therein and detecting the temperature of the object to be heated such as the pot bottom temperature. At the lower end of the pan sensor 43, there is provided a harness 43A for electrically connecting a control unit 200 (see FIGS. 2 and 3) for electrically controlling the stove 1 and a thermistor of the pan sensor 43. I have. When determining that a high temperature (for example, 250 ° C. or higher) is detected by the thermistor, the control unit 200 reduces the supply amount of the fuel gas to the stove burner 4 and automatically reduces the heating power in the burner head 42. Such a temperature detection system using the pan sensor 43 is required to be provided for each stove burner 4 in order to keep the stove 1 safe.

  At the substantially center of the front surface of the housing 2, two operation knobs 11, 11 each having a circular shape in a front view are provided side by side in the left-right direction. Each of the operation knobs 11 and 11 is operated to perform ignition, fire extinguishing, and heating power adjustment of each of the two stove burners 4 and 4.

  The two stove burners 4, 4 are attached to the bottom surface 25 of the housing 2 via the pair of mounts 30, 30 inside the opening 26. The mounting base 30 is formed in a rectangular shape that is long in the left-right direction in plan view, and is a member for fixing the stove burner 4 at a position one step higher than the bottom surface 25 of the housing 2. The pair of mounts 30 has a symmetrical structure. The mounting base 30 extends vertically and is disposed near the right wall portion 21 or the left wall portion 22 and a leg portion extending vertically and provided inside the opening 26 with respect to the leg 31. 32. A pan sensor fixing portion 33 for disposing a pan sensor 43 at the center of the burner head 42 and the burner main body 40 is provided at a substantially central portion in the left-right direction on the front side of the flat portion extending substantially horizontally at the upper ends of the legs 31 and 32. Is provided. An ignition electrode fixing portion 34 and a thermocouple fixing portion 35 for arranging the ignition electrode 44 and the thermocouple 45 near the burner head 42 are provided substantially at the center in the left-right direction on the rear side of the flat portion. . The stove burner 4 is fixed to the flat portion of the mounting base 30 with screws.

  The configuration of the bottom surface 25 of the housing 2 will be described in detail with reference to FIGS. The bottom portion 25 includes outer fixing portions 38, 38, inner fixing portions 39, 39, inclined surfaces 50, 50, recesses 60, 60, a first extending portion 70, second extending portions 80, 80, and a third extending portion. There is provided an installation portion 90, a fourth extension portion 100, and a fifth extension portion 110. The outer fixing portions 38, 38 are portions that protrude in a substantially elliptical shape in a plan view at a position closer to the right wall portion 21 or the left wall portion 22 at a position slightly behind the central portion in the front-rear direction of the bottom surface portion 25. The outer fixing portions 38, 38 are portions for fixing the lower ends of the legs 31 of the left mounting base 30 and the legs 31 of the right mounting base 30, respectively. The inner fixing portions 39, 39 are steps that are formed one step higher in a substantially square shape in plan view from the upper surface of the bottom portion 25, and are located at substantially the same position as the outer fixing portions 38, 38 in the front-rear direction. It is arranged at a predetermined interval toward the inside of the opening 26. The outer fixing portions 38, 38 are portions for fixing the lower ends of the legs 32 of the left mounting base 30 and the legs 32 of the right mounting base 30, respectively.

  The inclined surface portions 50, 50 are respectively disposed at positions between the outer fixing portion 38 and the inner fixing portion 39 at substantially the same positions in the front-rear direction as the outer fixing portions 38, 38 and the inner fixing portions 39, 39, as viewed in plan. It is a substantially rectangular surface that is slightly longer in the front-rear direction. Specifically, the left inclined surface portion 50 is disposed at a position between the left outer fixing portion 38 and the left inner fixing portion 39 in the left-right direction. The right inclined surface portion 50 is disposed at a position between the right outer fixing portion 38 and the right inner fixing portion 39 in the left-right direction. For this reason, in the state where the leg portions 31 and the leg portions 32 of the left and right mounting bases 30 are fixed to the left and right outer fixing portions 38 and the inner fixing portion 39, the left and right mounting bases 30 are inclined horizontally. They are arranged above the surface 50 (see FIGS. 2 and 3). That is, the left and right inclined surface portions 50, 50 are arranged at positions corresponding to the positions where the respective burner bodies 40 of the left and right stove burners 4, 4 are arranged in plan view. For this reason, the pan sensors 43, 43 are disposed at substantially the center of each of the inclined surfaces 50, 50 in plan view. The harness 43 </ b> A extending from the lower end of the pot sensor 43 extends from substantially the center of the inclined surface 50 toward the rear end 51 in plan view.

  As shown in FIGS. 4 and 6, the rear end 51 of the inclined surface 50 is located at the highest position of the inclined surface 50. The front end 52 of the inclined surface 50 is located at a position slightly lower than the rear end 51. Therefore, the inclined surface portion 50 is provided to be slightly inclined downward from the rear end portion 51 toward the front end portion 52. In the present embodiment, the inclination angle of the inclined surface portion 50 is about 2 ° to 3 °.

  The recesses 60, 60 are recesses that are recessed one step below the inclined surfaces 50, 50 around the inclined surfaces 50, 50. The concave portion 60 is provided around a position excluding the rear end portion 51 which is the highest position of the inclined surface portion 50, and has a substantially U-shape in plan view having a predetermined width in the left-right direction and the front-rear direction. That is, the concave portion 60 is disposed closer to the inside of the opening portion 26 of the inclined surface portion 50, to the front ridge line of the inclined surface portion 50, and to be closer to the outer side of the opening portion 26 of the inclined surface portion 50. It is provided to be depressed so as to surround each of the ridge lines. In the recess 60, a portion of the recess 60 which is arranged inside the opening 26 is provided with two holes 61 extending in the front-rear direction, penetrating the portion in the vertical direction, and extending in the front-rear direction. Two holes 62 extending in the front-rear direction are provided on the portion of the recessed portion 60 that is arranged near the outside of the opening 26 and extend in the front-rear direction through the portion in the vertical direction. In the portion of the recess 60 that is disposed on the front side of the inclined surface portion 50, two holes 63 penetrating the portion in the vertical direction and extending in the horizontal direction are provided side by side in the horizontal direction.

  Since the casing 2 of the stove 1 is formed to be thin and relatively thin in the vertical direction than other general stoves, the lower part of the harness 43A extending from the lower end of the pan sensor 43 is It is easy to approach or contact the bottom surface 25. In particular, in a state where an object to be heated such as a pan is being heated by the stove burner 4, the lower end of the pan sensor 43 is pushed down by the non-heated material, so that the lower end of the pan sensor 43 approaches the inclined surface 50. Cheap. For this reason, in particular, during cooking using the stove 1, the lower portion of the harness 43A is likely to be close to or in contact with the upper surface of the inclined surface portion 50. On the other hand, in the stove 1, a liquid such as a broth generated by heating the non-heated material by the stove burner 4 penetrates through the opening of the top plate 3 toward the inside of the housing 2, and the penetrated liquid is burned into the burner main body 40. May be dripped toward the inclined surface portion 50 disposed below.

  In the stove 1, since the inclined surface 50 is inclined at a predetermined inclination angle, the liquid dropped on the inclined surface 50 flows down the upper surface of the inclined surface 50 from the rear end 51 to the front end 52. The liquid flowing down the upper surface of the inclined surface 50 moves to the recess 60. Therefore, even when the liquid is dropped on the inclined surface 50, the liquid hardly remains on the upper surface of the inclined surface 50. The harness 43 </ b> A extends from a position at the center of the inclined surface 50 to a rear end 51 at the highest position of the inclined surface 50. For this reason, especially at the rear end portion 51 of the inclined surface portion 50 and in the vicinity thereof, the harness 43A is likely to approach or contact the upper surface of the inclined surface portion 50. On the other hand, the concave portion 60 is formed except for a position behind the rear end portion 51 in the inclined surface portion 50. Therefore, even if the liquid accumulates in the recess 60, it is difficult for the liquid to climb up to the rear end 51 of the inclined surface 50. In addition, the liquid that has moved to the concave portion 60 is discharged from one of the holes 61, 62, and 63 below the bottom portion 25, so that the liquid does not easily accumulate in the concave portion 60. For this reason, a problem that the liquid accumulated in the concave portion 60 runs on the upper surface of the inclined surface portion 50 does not easily occur. For this reason, even if the harness 43A is close to or in contact with the upper surface of the inclined surface portion 50, it is difficult for the harness 43A to be immersed in the liquid. Thus, even if the stove 1 employs the thin housing 2, it prevents the harness 43 </ b> A from causing a problem such as corrosion due to the adhesion of the liquid.

  The first extending portion 70 has a concave shape in the left-right direction so as to connect between the two concave portions 60, 60 at a position slightly closer to the front than the central portion in the front-rear direction of the two concave portions 60, 60. It is a groove that extends. The second extending portions 80, 80 are located at substantially the same position in the front-rear direction as the first extending portion 70, from the end of each of the two recesses 60, 60 that is closer to the outside of the opening 26, and extend from the first extending portion 80. It extends toward the side opposite to the side where the part 70 is provided. In other words, the right second extension portion 80 of the second extension portions 80, 80 extends from the right end of the right recess 60 near the right wall 21 of the housing 2 to the right end of the bottom portion 25. Extend to the right towards The left second extending portion 80 extends leftward from the left end of the left recess 60 close to the left wall 22 of the housing 2 toward the left end of the bottom surface 25. The first extending portion 70 and the second extending portions 80, 80 extend in the left-right direction from the left end to the right end substantially at the center of the bottom surface 25 in the front-rear direction. Therefore, the rigidity of the bottom portion 25 at the center in the front-rear direction is improved, and the strength of the housing 2 is improved.

  The third extending portion 90 is a portion that protrudes in the left-right direction at the rear portion of the bottom portion 25. A central portion in the left-right direction of the third extension portion 90 extends with a predetermined width in the front-rear direction. The left and right ends 91, 91 of the third extending portion 90 extend toward the left and right ends of the bottom surface 25 in an elongated shape having a width in the front-rear direction smaller than that of the central portion. Therefore, the rigidity of the rear part of the bottom part 25 is improved, and the strength of the housing 2 is improved.

  The fourth extending portion 100 is a convex portion extending in the left-right direction from the left end portion to the right end portion of the bottom surface portion 25 at a position on the front side of the inclined surface portions 50, 50 and the concave portions 60, 60. By providing the bottom portion 25 with the fourth extension portion 100, the rigidity of the front portion of the bottom portion 25 can be improved, and the strength of the housing 2 can be improved.

  The fifth extending portion 110 is a protruding portion that extends in the left-right direction at the center in the left-right direction of the bottom surface portion 25 at a position on the front side of the fourth extending portion 100. By providing the bottom portion 25 with the fifth extension portion 110, the rigidity of the front portion of the bottom portion 25 can be improved, and the strength of the housing 2 can be improved.

  In a general stove that employs a case that is thicker and larger than the stove 1, a structure such as a frame for improving the strength of the case is often provided inside the case. On the other hand, since the stove 1 employs the thin and small casing 2, it is more difficult to secure a space for disposing such a frame or the like inside the casing 2 as compared with a general stove. The stove 1 is provided with a first extension portion 70, a second extension portion 80, a third extension portion 90, a fourth extension portion 100, and a fifth extension portion 110 on the bottom surface portion 25, thereby forming a frame or the like. The strength of the housing 2 can be improved without being provided inside the housing 2. Note that the third extension portion 90, the fourth extension portion 100, and the fifth extension portion 110 extend in the left-right direction substantially in parallel with the first extension portion 70 and the second extension portions 80, 80. The rigidity of the bottom portion 25 is improved in cooperation with the one extension portion 70 and the second extension portions 80, 80, respectively.

  As described above, since the upper end of the pan sensor 43 is provided so as to contact the object to be heated above the stove burner 4, the harness 43A connected to the pan sensor 43 extends from the lower end of the pan sensor 43. It is generally provided as follows. For this reason, the lower portion of the harness 43 </ b> A is likely to approach or contact the bottom surface 25 of the housing 2. The stove 1 includes an inclined surface portion 50 at a position on the bottom surface portion 25 where the burner main body 40 of the stove burner 4 is arranged in a plan view. Further, a recess 60 is provided around the inclined surface 50. In this case, the harness 43A is easily arranged at the position of the inclined surface 50 in plan view. Even if a liquid such as broth enters the housing 2 and drops on the inclined surface 50, the liquid flows down the upper surface of the inclined surface 50 from the rear end 51 to the front end 52, Since the liquid is guided to the recess 60, it is difficult for the liquid to accumulate on the upper surface of the inclined surface 50. For this reason, even if the lower part of the harness 43A is arranged close to or in contact with the inclined surface 50, the harness 43A is unlikely to be immersed in the liquid. Therefore, even if the stove 1 has the thin casing 2, it is possible to avoid problems such as corrosion of the harness 43A.

  The concave portion 60 is provided around a position excluding the rear end portion 51 which is the highest position of the inclined surface portion 50. Therefore, the liquid dropped on the inclined surface 50 flows down the upper surface of the inclined surface 50 from the rear end 51 to the front end 52, and the liquid that has flowed down is guided to the recess 60. The harness 43A of the pot sensor 43 is arranged so as to extend from the position of the central portion of the inclined surface portion 50 toward the rear end portion 51 in plan view. For this reason, the stove 1 can prevent a portion of the harness 43A that is close to or in contact with the inclined surface portion 50 from being immersed in the liquid.

  The liquid guided from the inclined surface portion 50 to the concave portion 60 is discharged below the bottom portion 25 through the holes 61, 62, and 63 penetrating the concave portion 60 in the vertical direction. It is hard to collect. Therefore, the stove 1 can effectively prevent the lower portion of the harness 43A from being immersed in the liquid.

  Although the housing 2 is provided in a thin and small size, since the bottom portion 25 includes the first extension portion 70 and the second extension portions 80 and 80, the housing 2 can improve the rigidity of the bottom portion 25. it can. The stove 1 employs a thin and small casing 2, and can maintain the overall strength of the stove 1 even when a frame or the like for reinforcing the casing 2 is not provided inside the casing 2. .

  The bottom portion 25 includes the third extension portion 90, the fourth extension portion 100, and the fifth extension portion 110 in addition to the first extension portion 70 and the second extension portion 80. The rigidity can be further improved, and the overall strength of the stove 1 can be improved.

  Note that the present invention is not limited to the above embodiment, and various modifications are possible. The stove 1 is not limited to a configuration in which two stove burners 4 are arranged side by side in the left-right direction, and may be, for example, a configuration including one stove burner 4.

  In the above embodiment, the rear end portion 51 of the inclined surface portion 50 is the highest position in the inclined surface portion 50. For example, any one of the front end portion 52, the left end portion, and the right end portion of the inclined surface portion 50 is in the inclined surface portion 50. It may be the highest position. In this case, the end located at the position facing the end of the inclined surface 50 located at the highest position in the inclined surface 50 may be located at a position lower than the other ends. In this case, the harness 43A of the pot sensor 43 may be disposed so as to extend from the center of the inclined surface 50 toward the end of the inclined surface 50 located at the highest position of the inclined surface 50.

  The first extension portion 70 and the second extension portions 80, 80 may be arranged at different positions in the front-rear direction.
