An exhaust passage 24 is formed above the burner 4 for discharging the combustion gas from the upper part of the front surface of the appliance by its natural draft force. Not all the combustion gas is sucked by the blower fan 11, but a part of the combustion gas is formed in the exhaust passage 2 as described above.

Next, the series type thermocouple 21 will be described.
As shown in FIGS. 1 and 5, the series thermocouple 21 is composed of a rear thermocouple row 29 and a front thermocouple row 30 which are arranged in two rows in front of and behind the combustion surface 5. Then, as shown in FIGS. 6 to 8, the rear thermocouple array 29 includes a first metal member 31 made of a stainless steel plate having a substantially L-shaped outer shape and a constantan plate having a substantially L-shaped outer shape thinner than the first metal member 31. And a second metal member 32. The first metal member 31 is made of copper,
It may be made of chromel or iron.

The second metal member 32 is bent so that a lower end thereof has a step H to form a bent lower end 33, and a tip of the second metal member 32 is bent so that a step H is formed in a direction opposite to the lower end. Thus, the bent tip portion 34 is formed. A cutout portion 37b is formed in the bent tip portion 34. The front end and the lower end of the first metal member 31 are not bent to form a flat front end 36 and a flat lower end 35, respectively.
A thin notch 37a is formed in the flat tip portion 36. Assembly holes 38a are formed in the upper and lower parts of the first metal member 31, and two convex portions 39a having a height X are formed by press working slightly inside the assembly holes 38a. Similarly, the second metal member 32 is similarly provided with an assembly hole 38b at its upper and lower portions, and two convex portions 39b having a height X are formed by press working slightly inside the assembly hole 38b. The convex portions 39a and 39b are formed so that the first metal member 31 and the second metal member 32 project in the same direction when the metal members 31 and 32 are alternately arranged.

The post-thermocouple array 29 includes these metal members 3
1, 32 are alternately arranged and the ends thereof are welded in a zigzag shape. At this time, in order to ensure insulation between the metal members 31, 32, a thickness Y (X + Y = H)
The insulating sheet 40 is sandwiched between the metal members 31 and 32.
Assembling holes 38c are also opened in the upper and lower portions of the insulating sheet 40. The assembly hole 38c of the insulating sheet 40 is opened so as to be at the same position as the assembly holes 38a and 38b of the metal members 31 and 32 when the insulating sheet 40 is sandwiched between the metal members 31 and 32.

Then, as shown in FIG. 8, the first metal member 31 and the second metal member 32 are arranged such that the flat leading end portion 36 and the bent leading end portion 34 face each other, and the flat lower end portion 35 and the bent lower end portion. The parts 33 are alternately arranged so as to face each other, the insulating sheet 40 is sandwiched between the parts 33, and the leading ends and the lower ends of the metal members 31 and 32 are alternately welded and connected in a zigzag shape, thereby forming a plurality of thermoelectric elements. The paired elements 41 are connected in series to form the post-thermocouple array 29. At this time, the metal member 31,
32 and the insulating sheet 40 are not separated,
As shown in FIG. 5, the wire 49 is passed through the assembly holes 38a, 38b, 38c. The junction between the bent tip portion 34 and the flat tip portion 36 becomes the hot contact point a, and the junction point between the bent lower end portion 33 and the flat bottom portion 35 becomes the cold contact point b. In addition, the tip 34,
Since the cutout portions 37a and 37b are formed in 36, the heat capacity of the hot junction a is reduced.

As described above, each metal member 3 is provided by providing the step H at the tip and the bottom of the second metal member 32.
A gap having a distance H is formed between the first and the second portions to ensure insulation and satisfactorily radiate heat. In this case, each metal member 31, 32
Since the structure is such that the front end and the lower end are simply welded alternately, the metal members 31 and 32 move like an accordion, or the metal members 31 and 32 themselves are distorted, resulting in non-uniform distances. In a narrow space, it may become difficult to radiate heat, and the cold junction b may reach a high temperature and the thermoelectromotive force may decrease. Therefore, in the series thermocouple 21 of the present embodiment, the convex portions 39a and 39b are formed on the metal members 31 and 32.
Height X of convex portions 39a and 39b and thickness Y of insulating sheet 40
Is the distance H between the metal members 31 and 32. Therefore, when the metal members 31 and 32 are alternately arranged and the insulating sheet 40 is sandwiched therebetween, the convex portions 39a and 3a are formed.
9b comes into contact with the insulating sheet 40, and the metal members 31, 32
Secure a distance H between them. That is, the convex portions 39a, 39
Since the space between the metal members 31 and 32 is supported by b, the metal members 31 and 32 can be easily arranged at equal intervals at a predetermined pitch simply by arranging the metal members 31 and 32. Further, it is also possible to prevent the metal members 31 and 32 from moving like an accordion after welding, and to prevent the metal members 31 and 32 themselves from being distorted so that the distance becomes non-uniform.

Similarly to the rear thermocouple row 29, the front thermocouple row 30 has a first metal member made of a stainless steel plate having a substantially L-shaped outer shape and a constantan plate having a substantially L-shaped outer shape thinner than the first metal member. And a second metal member consisting of The metal member of the front thermocouple row 30 is connected to the rear thermocouple row 29.
It is formed smaller than the metal members 31 and 32. Then, the front thermocouple row 30 and the rear thermocouple row 29 are housed in a U-shaped mounting frame 42 as shown in FIG. A thermocouple 21 is formed. Between the rear thermocouple row 29 and the front thermocouple row 30,
By sandwiching the partition plate 44 and sandwiching the insulating bands 45 between the front and rear thermocouple rows 30 and 29 and the mounting frame 42, the holding plate 43, and the partition plate 44, respectively, the rear thermocouple row 29 and the front thermocouple row are formed. Insulation with 30 is ensured. The rear thermocouple row 29 and the front thermocouple row 30 are connected in series by a lead wire 46. Further, as described above, the rear thermocouple train 29 and the front thermocouple train 30 are
By fixing and, the insulating sheet 40 can also be prevented from coming off.

The series type thermocouple 21 is attached so that its hot junction a faces and adjoins the combustion surface 5 of the burner 4 and its cold junction b faces the medium-cooled air intake 15. That is, cold junction b
Is located in the flow of air sucked by the blower fan 11 through the medium-cooled air suction port 15.

By the way, the work of arranging the metal members 31 and 32 and welding the leading end and the lower end thereof is performed by the metal members 31 and 3.
2 is a difficult work because it is easy to be disjointed, and the thermocouple row is sandwiched between the mounting frame 42 and the holding plate 43, and the series type thermocouple 2
The work of assembling 1 is also a troublesome work because the insulating sheet 40 is easily removed. Therefore, in the present embodiment,
First metal member 31, second metal member 32, and insulating sheet 40
Assembly holes 38a, 38b, 38c respectively provided in and
In addition, the wire member 49 is used to prevent the metal members 31 and 32 and the insulating sheet 40 from coming apart, and then the ends are welded to assemble the series thermocouple 21. The wire rod 49 is pulled out after these operations.

According to the stove 1 having the above-described structure, when the ignition lever 27 is operated, the fuel gas is ejected from the entire surfaces of the four combustion plates 7 and is ignited by the discharge from the electrodes (not shown). Then, the user in front of the appliance is directly warmed by the radiant heat from the combustion plate 7 which has red heat. Further, when the heat power switching lever 28 is operated, the fuel gas is switched between the low heat power setting in which the fuel gas is jetted from the entire surfaces of the four combustion plates 7 and the low heat power setting in which the fuel gas is jetted from only two surfaces provided in the lower burner main body 9 is switched. The heating power of 4 can be adjusted according to the user's preference. When the burner 4 burns, the combustion heat of the burner 4 heats the hot junction a of the series thermocouple 21 to generate thermoelectromotive force.
The blower fan 11 is driven. Then, the blower fan 11 sucks the combustion gas of the burner 4 from the hot air suction port 12 and the external air sucked into the device through the suction port 17 from the upper, middle, and lower cool air suction ports 14, 15, 16. By blowing out the air-fuel mixture from the hot air outlet 10 toward the front of the appliance, the entire room is uniformly heated by the hot air.

At this time, since the cold junction b of the series type thermocouple 21 is attached so as to face the medium cold air suction port 15, the cold junction b is positioned in the flow of air sucked in the medium cold air suction port 15. As a result, the cold junction b can be forcibly cooled. Therefore, the temperature difference between the hot junction a and the cold junction b can be increased to efficiently obtain the thermoelectromotive force. Moreover, since the medium cold air suction port 15 is provided in the suction cylinder 22 branched from the fan supply cylinder 13, the suction position can be freely laid out and can be arranged very close to the cold junction b. Therefore, the air flow can be concentrated on the cold junction b, and the cooling effect of the cold junction b is further enhanced. Further, such cooling air, after being sucked into the device through the intake port 17, flows through the spaces on the left and right of the fan-supplied cylinder 13 and wraps around to the front surface of the fan-supplied cylinder 13. Therefore, the cooling air is not heated by the combustion gas, and the cold junction b can be satisfactorily cooled by the cooled air.
In addition, the notches 37a and 37b are formed in the tip portions 34 and 36.
To reduce the heat capacity of the hot junction a,
The temperature of the hot junction a rapidly rises and the hot junction a is heated to a high temperature, so that the output of the series thermocouple 21 can be further improved.

Further, the inside of the fan supply cylinder 13 is divided by a partition plate 18 into a cool air passage 20 on the rear side of the equipment and a warm air passage 19 on the front side, and the air sucked from the upper cool air suction port 14 is cold air. The combustion gas flowing through the passage 20 and sucked from the warm air inlet 12 flows through the warm air passage 19. For this reason,
The heat transfer from the hot combustion gas to the back of the equipment is performed by the cold air passage 20.
The temperature can be prevented from rising on the back side of the device by using the shield, which increases safety. Moreover, since the inside of the fan supply cylinder 13 is divided by the partition plate 18 in this way, it can be implemented at low cost. Further, when the air in the device is sucked from the lower cool air intake port 16 and the medium cool air intake port 15 provided in the lower part of the fan supply cylinder 13, the inside of the device becomes a negative pressure and is provided on the rear surface of the body case 3. The air outside the instrument is sucked into the instrument from the intake port 17. For this reason, the back surface of the appliance can be forcibly cooled by the flow of unheated air outside the appliance to lower the temperature, which further enhances safety. Moreover, like this, the fan-supplied cylinder 1
Since it has a simple structure in which the middle and lower cool air suction ports 15 and 16 are opened in the lower part of 3, it can be implemented at low cost.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the present invention. is there. For example, in FIG.
As shown in FIG. 0 and FIG. 11, the cold junction b is located inside the suction cylinder 322 by extending the tip of the suction cylinder, notching the upper surface of the tip and inserting the cold contact b there. You may. In this case, most of the air sucked from the medium cold air suction port 315 comes into contact with the cold contact b, and the cooling effect on the cold contact b is further increased.

According to the described infrared stove with fan, the heat transfer from the hot combustion gas to the back of the appliance is blocked by the cold air passage,
It is possible to prevent the temperature rise on the back of the device and increase safety. Moreover, since the suction passage is divided by the dividing means, the construction can be inexpensive.

Further, according to the infrared stove with fan according to the second aspect of the present invention, the temperature can be lowered by forcibly cooling the back surface of the appliance by the flow of unheated air outside the appliance, which is safe. Will increase. Moreover, since the second cold air suction port is provided in the middle of the suction passage and the intake port is provided on the back surface of the device, it can be implemented at low cost.

Further, according to the infrared stove with a fan of claim 3 of the present invention, the heat transfer from the high temperature combustion gas to the back of the appliance can be blocked by the cold air passage, and
Since the back surface of the device can be forcibly cooled by the flow of unheated air outside the device, the cooling effect on the back surface of the device is further increased.
