Description

  The present invention relates to a gas stove with a grill provided with a grill part at the lower part of the stove part provided with a stove temperature sensor, and in particular, does not affect the temperature sensor for the stove from the heat from the grill part. It is related with the technique for making it.

  Conventionally, a built-in type gas stove 1 ′ without a grill is known (for example, see Patent Document 1). As shown in FIG. 8, this gas stove 1 ′ is a one in which the stove burners 3 are arranged in a horizontal row by arranging the two stove burners 3 diagonally on a substantially square top plate 8. Automatic structure to prevent cooking mistakes and tempura oil fires due to overheating in a structure in which the width dimension can be reduced as compared with the above. It has a fire extinguishing function.

  However, in the gas stove 1 ′ shown in Patent Document 1, only one stove burner 3 is provided with the temperature sensor 10 for the stove, and further, a grill used for cooking fish is provided. Not. Nevertheless, there is a growing demand for safety and convenience in the market, and there is a demand for the temperature sensor 10 for the stove to be provided in the entire mouth of the stove burner 3, and the lower part of the gas stove 1 ′. There is a growing demand for a grill that is used for cooking fish.

  Therefore, in order to meet market demands, for example, a temperature sensor for the stove is provided at the entire mouth of the gas stove 1 ′ equipped with a grill 20 used for cooking fish grilling under the stove burner as shown in FIG. 10 is equipped with a grill under the stove burner 3, the temperature sensor for the stove provided in the stove section 2 is affected by the combustion of the grill burner 21 when the grill is used. Therefore, when the stove and the grill are used at the same time, the temperature sensor 10 for the stove cannot accurately detect the temperature of the pan bottom, and recognizes it higher than the actual temperature. May cause malfunction.

  If the grill is arranged at an intermediate position between the two stove burners 3, the influence of heat on the stove temperature sensor 10 due to the combustion of the grill burner 21 can be slightly mitigated. The space inside the stove 1 'is divided into left and right regions by the central grill, which hinders the arrangement of components such as gas valves, burner ignition igniters, and control electrical boards. Therefore, the grill has to be unevenly distributed on either the left or right side. As a result, the influence of heat on the temperature sensor 10 for the stove is inevitable.

  FIG. 9 shows another conventional example. In a gas stove 1 ″ having a top plate 8 covering the top surface of the stove body 7, an air discharge passage 80 is provided between the bottom surface of the virtually plate 9a and the top surface of the top plate 8. When the stove burner 3 is burned, the air under the top plate 8 is made to flow in the direction of the arrow d so that the air is discharged from between the outer peripheral edge of the virtually plate 9a and the upper surface of the top plate 8 in the outer peripheral direction. Thus, a configuration is known in which diffusion of combustion gas is prevented and thermal efficiency is improved (see, for example, Patent Document 2).

  In the gas stove 1 "disclosed in Patent Document 2, since the secondary air for combustion of the stove burner 3 flows under the top plate 8, a stove temperature sensor is temporarily installed and When equipped with a grill, it is possible to cool the top surface of the grill by devising how the secondary air flows under the top plate 8, and the effect of heat on the temperature sensor for the stove Can be relaxed.

  However, in the gas stove 1 ″ of Patent Document 2, an opening 81 for allowing the combustion secondary air to pass near the boundary between the stove burner 3 and the top plate 8 is necessary. Characteristic of “Konro 1”, “If the top plate 8 and the stove burner 3 are sealed, even if there is spilling during cooking, the hot water and soup that has been spilled will remain in the equipment body under the top plate 8 The inconvenience that the structure of “does not enter” is lost.

For this reason, the conventional gas stove cannot sufficiently meet the market demand for safety and convenience.

In addition, since it is easier to use the high thermal power burner on the front side, the high thermal power burner is placed on the left front side, and the standard burner is placed on the right rear side, but on the contrary, the high thermal power burner is placed on the right front side. The location of the stove burner 3 can be changed as appropriate, such as placing the standard burner in the back left or placing the high thermal power burner in the back. Further, both of the two stove burners 3 may be high-heat burners. Further, a sealing member (not shown) is sealed between the stove burner 3 and the opening 8a of the top plate 8 so that the broth does not enter.

  On the top plate 8, virtues 9 for receiving and supporting an object to be heated (such as a pan) for the stove burner 3 are placed.

  The stove body 7 is provided with a control unit (not shown) composed of a microcomputer configured to execute various controls. Further, each stove burner 3 is provided with an ignition plug (not shown) as an ignition device for executing an ignition operation and a thermocouple (not shown) for detecting an ignition state. When a stove utensil stopper operation knob 31 to be described later is pushed and operated to the “ignition” angle, the gas is supplied to the stove burner 3, the ignition igniter is energized, and the gas is ignited by the continuous spark. When the gas is ignited, the temperature of the thermocouple provided in each stove burner 3 rises, and the control unit maintains the energization of the safety valve, whereby the gas supply is continued and the combustion is continued. If the stove burner 3 is extinguished due to spillage, etc., the temperature of the thermocouple will drop, and if the control unit detects the fire extinguishing of the burner, the power supply to the safety valve will be cut off and the gas supply to the burner will stop. ing.

  Moreover, the temperature sensor 10 for the stove which consists of the thermistor for contacting the bottom part of to-be-heated material (pan etc.) and detecting the temperature is provided in all the mouths of the said 2 mouth stove burner 3. As shown in FIG. The stove temperature sensor 10 is provided so as to pass through the center of the annular stove burner 3, and the temperature-sensitive head of the stove temperature sensor 10 is biased upward by a spring. A predetermined fire extinguishing temperature (for example, 270 ° C.) is detected by coming into contact with the bottom surface of the heating container placed on the container.

  On the other hand, the grill part 20 is provided with a grill net (not shown) as a placing part for placing an object to be cooked such as fish in a box-shaped grill box 22 formed in a box shape opened on the front surface. It is comprised, and the grill burner 21 for heating a to-be-cooked item from the upper surface is provided.

  The grill warehouse 22 of this example is located substantially directly under the high-heat-power burner located in front of the stove part 2. In this manner, the grill cabinet 22 is unevenly distributed on the left front side, so that a space can be secured in the right side portion of the stove body 7, and electrical components such as a gas valve, an ignition igniter, and a control unit can be easily arranged. Yes.

  An exhaust pipe 23 for guiding the combustion exhaust gas from the grill warehouse 22 to the grill exhaust port 5 located at the rear upper surface of the stove section 2 rises obliquely rearward from the rear portion of the grill warehouse 22 at the rear portion of the grill warehouse 22. It is provided.

  The grill burner 21 is also provided with an ignition plug (not shown) as an ignition device for performing an ignition operation and a thermocouple (not shown) for detecting an ignition state, similar to the stove burner 3. That is, when the grill appliance plug operation knob 32 is pushed and operated to the “ignition” angle, the gas is supplied to the grill burner 21, the ignition igniter is energized, and the gas is ignited by the continuous spark. When the gas is ignited, the temperature of the thermocouple provided in the grill burner 21 rises, and the control unit maintains the energization of the safety valve so that the gas supply is continued and the combustion is continued. If the grill burner 21 is extinguished, the temperature of the thermocouple decreases, the control unit detects the extinguishing of the burner, cuts off the energization to the safety valve, and stops the gas supply.

Further, as shown in FIG. 7, two stove appliance plug operations are provided on the front side of the grill cabinet 22 as an operation unit 30 for igniting and extinguishing the stove burner 3 and the grill burner 21 and adjusting the heating power. A total of three knobs 31 and one grill appliance plug operation knob 32 are provided, and a battery storage unit 37 that is opened and closed by a lid 38 is provided at the side of the appliance plug operation knob 31 for the stove. It has been. An operation display panel 36 including a display unit 34 and a sensor release switch 33 is installed in a part of the battery storage unit 37. The display unit 34 of this example will be described. First, the grill combustion lamp 34a ignites the grill and the LED is turned on when ignition is detected. The grill burner 21 is located on the upper surface in the grill cabinet 22, and it is difficult to visually confirm the ignition to the grill burner 21, so that the grill combustion lamp 34a is easy to use. The battery replacement sign lamp 34b blinks when the series voltage of the battery mounted in the battery storage section 37 is 2.1 V or less, and notifies that it is time to replace the battery. The sensor release lamp 34c is turned on when the sensor release mode is set by pressing the sensor release switch 33 for 3 seconds. Here, the sensor release switch 33 is for switching to the sensor release mode when performing high temperature cooking such as fried food or fried food in the stove unit 2.

Lights up to make it possible to determine at a glance that the sensor release mode has been set.

  Here, an embodiment of the present invention will be described. As shown in FIGS. 1, 2, and 3, the grill burner 21 of the grill portion 20 is formed along a gap space between the lower surface of the stove base 6 in the stove main body 7 and the upper surface of the grill top plate 24 of the grill cabinet 22. The ventilation path 11 is provided so as to shield the heat transfer path from the temperature sensor 10 to the stove. A front end portion 11 a of the air passage 11 communicates with an intake port 4 provided in the stove portion 2, and a rear end portion 11 b is opened in the vicinity of the grill exhaust port 5, and the stove burner 3 and the grill burner 21. When the two are used at the same time, the combustion heat of the grill burner 21 is prevented from reaching the temperature sensor 10 for the stove by the air passage 11.

  In this example, the member constituting the air passage 11 is constituted by the air passage constituting member 12 formed in a U-shape with a flat cross-section with the upper part opened, and the above-described stove stand 6. That is, the air passage 11 is formed in such a form that the upper surface opening of the U-shaped air passage constituting member 12 is brought into contact with the lower surface of the stove base 6. In the example of FIG. 1, the width A of the air passage constituting member 12 is wider than the horizontal width of the stove burner 3, and the length B of the air passage constituting member 12 is the distance from the front surface of the stove main body 7 to the grill exhaust port 5. And approximately the same dimensions. Further, the front end of the lower surface of the air passage constituting member 12 reaches, for example, the lower vicinity of the plurality of upper and lower intake ports 4 in the upper and lower rows opened on the front surface of the main body 7. Further, the entire lower surface of the air passage constituting member 12 is disposed with a gap 13 (FIG. 3) from the upper surface of the grill top plate 24.

  According to the above configuration, when the grill burner 21 is ignited and combustion is started, the high-temperature combustion exhaust gas in the grill warehouse 22 is discharged to the outside through the grill exhaust port 5. When the high-temperature combustion exhaust gas passes through the grill exhaust port 5, the grill exhaust port 5 is also heated, and the temperature at the periphery of the grill exhaust port 5 is also high. As a result, an upward airflow is generated at the grill exhaust port 5, the temperature of the rear end portion 11 b of the air passage 11 located in the vicinity of the grill exhaust port 5 is also increased, and an upward airflow is generated. It will be in the state to draw in. As a result, the inside of the air passage 11 becomes negative pressure, and the indoor air is sucked into the air passage 11 from the air inlet 4 provided on the front surface of the stove body 7, and the inside of the air passage 11 is shown by an arrow E in FIGS. The air passage 11 is cooled in the direction indicated by, and thereafter, the air flows in the vicinity of the grill exhaust port 5 from the rear end portion 11b of the air passage 11 and is discharged to the outside. As a result, the grill 20 and the temperature sensor 10 for the stove are shielded by the space of the air passage 11, and at the same time, the air flowing in the air passage 11 is unheated air outside the body, and the air passage 11 is cooled by air cooling.

  As described above, during the grill combustion, the grill chamber 22 and the temperature sensor 10 for the stove are shielded by the air flowing through the air passage 11 and the air passage 11, so that the heat from the grill chamber 22 is affected. Covering the temperature sensor 10 for the stove is suppressed. Accordingly, there is no possibility that the temperature sensor 10 for the stove erroneously detects that the pan bottom temperature is higher than the actual temperature, and inconvenience due to malfunction such as premature disconnection can be avoided.

  In addition, since air can be flowed into the air passage 11 from the outside by using the rising air flow generated at the grill exhaust port 5, the air passage 11 can be cooled easily and economically without using power from a pump or the like. There are advantages you can do.

  Further, even if the grill burner 21 is disposed almost directly below the temperature sensor 10 for the stove, the thermal effect on the temperature sensor 10 for the stove can be eliminated by the heat shielding effect by the air passage 11. This eliminates the restrictions and increases the degree of freedom in design.

  The stove stand 6 installed in the stove part 2 is a member necessary for defining the relative position between the stove burner 3 and the opening 8a provided in the top plate 8. Since this stove stand 6 has a structure that also serves as a member constituting the upper surface of the air passage 11, there is an advantage that the members constituting the air passage 11 can be reduced and the air passage 11 can be constructed at low cost. is there.

  Further, since the member constituting the lower surface of the vent passage 11 reaches the vicinity of the lower side of the intake port 4 provided on the front surface of the stove body 7, a plurality of intake ports 4 opened on the front surface of the stove body 7 are provided. When the air is drawn into the air passage 11, the hot air from the grill 22 can be prevented from flowing into the air passage 11, and the air passage 11 can be sufficiently cooled by the low-temperature outside air. In addition, since a part of the upper surface of the U-shaped air passage constituting member 12 constituting the air passage 11 on the front end portion 11a side is opened inside the stove body 7, the outside air taken into the air passage 11 can be removed. There is also an advantage that a part is supplied to the stove burner 3 side and effectively used as burner combustion air.

  Furthermore, in the present embodiment, as shown in FIG. 2, the gap between the grill top plate 24 and the bottom surface of the airflow path component 12 is wider at the front part (left side in FIG. 2) and toward the rear part (right side in FIG. 2). It is narrower. Thereby, the temperature rise of the outside air flowing in from the front end portion 11a of the air passage 11 is suppressed, and on the other hand, the draft end (updraft) is increased by heating at the rear end portion 11b of the air passage 11. The exhaust performance will be improved.

  Further, as shown in FIG. 1, the front end portion of the stove stand 6 below the stove temperature sensor 10 is opened in an inverted U shape in plan view, and the outside air flowing in from the front end portion 11 a of the air passage 11 is present. It becomes easy to flow in the vicinity of the temperature sensor 10 for the stove, and the cooling effect of the temperature sensor 10 for the stove is further enhanced.

  Further, as shown in FIG. 3, since the entire lower surface of the ventilation path constituting member 12 is disposed with a gap 13 from the upper surface of the grill top plate 24, a cooling effect is also obtained by air flowing into the gap 13. There is also an advantage that the cooling effect of the temperature sensor 10 for the stove can be obtained multiple times with the air passage 11.
