Description

[Detailed description of the invention] [Purpose of the invention] Industrial application field The invention is a duct type roaster that exhausts exhaust gas outdoors, which can be moved and rearranged, or used in a smokeless roaster installed at home. This invention relates to a smokeless roaster that can be stored when not needed.

Conventional technology In the past, non-duct type roasters processed exhaust gas such as burning smoke inside the roaster body and exhausted it indoors, allowing the roaster body to be placed freely within the store. However, there are problems in processing waste heat, etc., and due to such measures, non-duct type roasters have the disadvantage of being expensive.

On the other hand, with duct-type roasters, exhaust gas such as burning smoke is exhausted outdoors through an exhaust duct installed under the floor, and there is no need to treat the exhaust gas.However, since the roaster body is fixed to the exhaust duct, It had the disadvantage that it could not be moved.

Therefore, even in duct type roasters,
A roaster that can be rearranged has been developed (Japanese Patent Laid-Open No. 62-217918), but this type of roaster uses tubes and joints to connect the exhaust duct and the exhaust part of the roaster body. Therefore, it has the disadvantage that it is impossible to install an exhaust system (adjustment using a moving tube described in Japanese Utility Model Publication No. 57-49940) for cooling exhaust gas and optimizing suction pressure, which is necessary in a duct type roaster. was.

In addition, such smokeless roasters also have drawbacks such as difficulty in adjusting, repairing, and replacing the roasting unit, and lack of measures to prevent burnout, backfire when clogged, and abnormal combustion.

Problems to be Solved by the Invention The present invention does not require exhaust gas treatment inside the roaster and exhausts it outdoors, allows the duct-type roaster body to be freely rearranged, and furthermore cools and extracts the exhaust gas. To provide a smokeless roaster which optimizes the pressure and stores the smokeless roaster separated from the exhaust duct under the floor when unnecessary.

[Structure of the idea]

Means for Solving the Problems The present invention is based on the above-mentioned conventional technology, and in view of the problem that rearranging the duct type roaster is difficult, the exhaust duct and the roaster body can be freely separated, and the intake air can be freely adjusted as an outside air intake port. Make a hole,
Furthermore, by integrally forming an oil drop part with a downwardly tapered diameter at the lower end of the outer box to prevent oil from escaping from the intake hole, it is possible to change the arrangement, and the cooling of exhaust gas and suction pressure are optimized. The purpose of this invention is to solve the above problem by doing the following.

Function This invention separates the roaster body from the exhaust duct by pulling up the connecting tube at the connecting part of the roaster body, separating the lower end of the connecting tube from the fixed tube of the connecting box, and fitting the supporting protrusion into the supporting notch. Then, hold the connecting tube in the raised position at the bottom of the roaster body and remove the gas supply pipe.
The fixation of the roaster body to the exhaust duct, floor, etc. is released, and the roaster body is moved.
Rearrange and store.

In addition, by rotating the air volume adjustment ring, the intake amount of outside air is adjusted by adjusting the matching area (communication area) between the intake hole of the guide tube and the intake hole of the air volume adjustment ring, and the lowest end of the exhaust part is It is tapered inwardly so as not to contact the guide tube and the air volume adjustment ring, and oil and fat fall from the oil falling part to the center of the guide tube and do not escape from the air intake hole to the outside of the air volume adjustment ring.

Also, selectively place a rostre, a trivet, or a wire mesh on the placement part of the pot and serve it with either yakiniku, hotpot, or fish and shellfish dishes, and in the case of yakiniku dishes using the rostol, place the meat on the rostol.

Next, the action of the smoker -free roaster according to the book is selected on the placement portion 26 of the pot body 15, and the Lostle 27, Gotoku 32 or wire mesh 36 are placed, and in any dish of yakiniku, pot or fish shellfish. In the case of yakiniku dishes using the rostle 27, the meat is placed on the rostle 27 and grilled, and the meat juices are poured into the grooves 29, 29a...
When cooking in a pot using the trivet 32, the pot is placed on top of the protrusions 33, 33a of the trivet 32 and heated, and the wire mesh 36 is used. In the case of grilling, fish and shellfish (meat can also be used) are placed on the wire mesh 36 and grilled, and when cooking the fish and shellfish, the contact area between the wire mesh 36 and the fish is small so that the skin of the fish does not come off, and the shellfish, shellfish, In the case of round-shaped shrimp or crabs, radiant heat is used to properly grill them without limiting the heating area.

Also, during the above cooking, the radiant heat from the burner 44 reaches the ceramic charcoal 14, and when the ceramic charcoal 14 is heated, the far infrared rays radiated cause the cooking placed on the roaster 27 or wire mesh 36 above to be heated. It is used to grill things, and the radiant heat is easily transmitted to the inside, and it burns evenly and to a state similar to charcoal.

When grilling meat or fish and shellfish as described above, the exhaust duct 50, the connecting box 51, the connecting part 4
9. When a suction pressure is applied to the exhaust part 4 and the outer box 5 of the roaster body 1, the smoke that rises as the food is baked is released together with the exhaust gas into the inner box 7 located around the upper part of the roaster 27 and the wire mesh 36, etc. surrounding wall 16
The exhaust gas is sucked in from the intake holes 17, 17a, etc., and passes through the suction channel 6, the outer box 5, and the exhaust part 4 while being cooled, and then continues to the joint part 49 (which sucks in a small amount of outside air as described later). The air passes through the connecting box 51 and is exhausted to the outside from the exhaust duct 50.

Also, when sucking the exhaust gas, the intake holes 17, 17a, . . . , which communicate with the suction flow path 6 of the roaster body 1
is bored in the circumferential wall 16 of the inner box 7. Therefore, in the conventional suction structure, the intake hole is bored in the circumferential wall of the top plate. However, with the above structure, these drawbacks have been overcome. Lost 27 and Gotoku 3 that solved the problem and cooked the food.
2 or the hot air of the burner 44 is effectively utilized by sucking the exhaust heat above the wire mesh 36, and the top ring 37, which is placed on the upper part of the peripheral wall 16 and closes the upper opening 38 of the outer box 5, is a simple ring shape. for,
The structure, manufacturing, attachment/detachment, and cleaning operations of the top ring 37 are facilitated.

When the exhaust gas is sucked in this way, the connecting box 51
Inside, the exhaust gas flow from above bends at right angles to the side opening 71 inside the cylindrical drain pan 70, and the oil particles fall to the bottom of the drain pan 70 due to inertia and adhere to the adsorbents 74, 74a... Also, after passing through the drain pan 70, it is bent in the connection box 51 and exhausted from the exhaust duct 50, and at this time, oil particles are also deposited on the bottom of the connection box 51 due to inertia and turbulent flow within the connection box 51. The absorbent material 7 falls and passes through the suction hole 73 in the lower part of the drain pan 70.
4, 74a..., and after oil particles adhere to the drain pan 70 and connection box 51 due to changes in air pressure, they flow downward and finally reach the adsorbents 74, 7.
4a..., and when a large amount of oil and fat is adsorbed by the adsorbents 74, 74a..., the connection box 5
After separating the connecting portion 49 of the roaster main body 1 from the connecting box 51, the drain pan 70 is pulled upward from the connecting box 51 and the adsorbents 74, 74a, . . . are replaced.

In addition, in such a flow path, the exhaust gas is attracted to the outer peripheral flow path (on the opposite side of the exhaust duct 50) where the suction pressure is weaker than in the inner peripheral flow path (closer to the exhaust duct 50) where the area of the opening 71 of the drain pan 70 is larger. Since the passage of the exhaust gas is gradually made easier, the exhaust gas from the roaster body 1 is sucked in at the same flow rate at every point in the cross section.

Next, to explain safety during heating and cooking, etc., first, when operating the ignition, when the knob 103 of the gas cooker 99 of the cooker unit 21 is rotated, raw gas is blown from the pilot nozzle 106 to the burner 44, and the pilot nozzle A spark is ignited from a sparker 107 located close to 106 to ignite the flying gas, and the ignited flying gas reaches the burner 44,
The raw gas ejected from the nozzles 47, 47a, etc. of the inner box 7 is ignited to heat and cook the food, and the inner box 7 a connecting part 12 that connects the inside and the inside of the stock unit 21;
The flame sensor 115 does not detect the ultraviolet rays emitted from the flame of the burner 44 through the light path formed by the sensor hole 116 drilled in the flame blocking plate 96, so the gas supply is cut off and the roaster body 1 is not required during use. When the temperature exceeds the temperature, the temperature sensor 123 cuts off the gas supply.

Furthermore, as described in the above operation, the gas supply is cut off in case of ignition error or extinction, but even in this case, unburned gas is released from the pilot nozzle 106 when the ignition operation does not initially ignite, causing the combustion unit to shut off. 21 is full, or when the gas is extinguished, the burner 44's crater 47,
Due to the clogging of the burner 47a..., some unburned gas escapes into the combustion unit 21 at the connection part 105 between the introduction part 45 of the burner 44 and the main nozzle 104, and therefore, when the burner 44 is re-ignited or
In the event that the unburned gas that filled the Kotoku unit 21 backfires or burns abnormally due to flying sparks,
The flame shielding plate 96 of the gas control stay 92 prevents flames or hot air from directly propagating to the control device 122, etc. inside the gas control unit 21, and the ignition hole 114 and sensor hole 116 drilled in the flame shielding plate 96 prevent a large amount of flame or hot air from propagating directly to the control device 122, etc. Shielding plates 118, 119, 12 are provided for the introduction part 45 of the burner 44 from which unburned gas escapes.
The suction hole 89 of the bottom plate 79 of the control box 76 of the control unit 21 is shielded by the
In this case, the introduction part 45 of the burner 44 is shielded by the shielding plate 117 to prevent flame or hot air from propagating downwardly to the outside from the suction hole 89, and the nozzle hole 11
3, the main nozzle 104 is approximately the same size, and the unburned gas, flame, or hot air is sent to the unit 2.
This makes it difficult to flow within 1.

Next, rearrange the roaster body 1 and connect the joint 4.
To explain the intake of outside air at step 9, the connecting tube 63 of the connecting portion 49 of the roaster body 1 is pulled upward and the lower end of the connecting tube 63 is separated from the fixed tube 68 of the connecting box 51, thereby separating the roaster body 1 and the exhaust duct 50. Then, by lifting and rotating the connecting tube 63, the supporting protrusion 62 of the guide tube 56 is fitted into the supporting notch 66 of the connecting tube 63, thereby holding the connecting tube 63 in the raised state at the lower part of the roaster body 1 and supplying gas. Remove the pipe 127 and remove the roaster body 1.
The fixed state to the exhaust duct 50, the floor 19, etc. is released, the roaster body 1 is moved, rearranged, and stored, and the opening 52 of the floor 19 is released.
Then, the lid is closed with the lid body 53.

In addition, outside air intake, which was conventionally performed by a moving tube that moves up and down and an exhaust part (tapered shape) of the roaster main body, is performed by the guide tube 56 and the air volume adjustment ring 59. That is, by rotating the air volume adjustment ring 59, the guide tube 56 is taken in. intake hole 57,
57a... and intake holes 60, 6 of the air volume adjustment ring 59
The intake amount of outside air is adjusted by adjusting the matching portion (communication area) of the guide tube 56 and the air volume adjustment ring 5.

[Effect of idea]

In short, the present invention provides the guide tube 56 in the exhaust section 4 of the roaster main body 1, installs the exhaust duct 50 under the floor 19, and connects the connecting tube 63 that can freely approach and separate from the exhaust duct 50 to the guide tube 56. Since the roaster body 1 and the exhaust duct 50 can be connected and separated by the connecting tube 63 of the connecting part 49, the exhaust gas generated from the cooking part 3 is transferred to the exhaust duct 5.
Even if exhaust heat and harmful components are not processed, the smokeless roaster can be rearranged in the store depending on the number of customers, customer quality, and season, and when installing a smokeless roaster for home use. By installing the roaster body 1 on the floor 19 only when necessary, storing the roaster main body 1 when it is not necessary, and closing the opening 52 of the floor 19 with the lid 53, a flat floor 19 can be obtained. An air volume adjustment ring 59 is rotatably attached to the tube 56, and the guide tube 56 and the air volume adjustment ring 59 have intake holes 57, 57a, . . .
0, 60a..., respectively, so even in a smokeless roaster in which the roaster main body 1 and the exhaust duct 50 are separable, the intake holes 57, 57a..., the intake hole 6 can be adjusted by rotating the air volume adjustment ring 59.
By adjusting the communication area of 0, 60a..., the intake amount of outside air can be adjusted.

In addition, since an oil falling part 55 with a downwardly tapered diameter is provided at the lower end of the guide tube 56, even if the oil and fat sucked in at the same time as the exhaust gas during cooking flows down from the inner wall surface of the outer box 5, the outer box 5 Since the lowermost end of the guide tube 56 and the connecting tube 63 are not in contact with each other, the intake hole 5 of the guide tube 56
7, 57a... and the intake hole 6 of the connecting tube 63
It can prevent leakage from 0,60a...

In addition, since the gap cover 129 is attached to the connecting tube 63 so that it can slide up and down, the floor 19
The gap between the openings 52 can be closed, and therefore, the outside air flowing into the room from outside can be blocked and the heating and cooling load can be reduced.

In addition, a placing part 26 is provided on the upper part of the inner box 7, and a rotor 27, a trivet 32, and a wire mesh 36 are provided so as to be compatible, and any one of them can be selectively placed on the above-mentioned placing part 26. I made it so that
The roaster body 1 can be used for cooking meat, fish and shellfish, and hot pots, making it versatile.
Such dual-purpose use is useful when using and installing a The smokeless roaster used for commercial use can also be used for home use, and since a circular protrusion 31 is provided on the bottom of the roaster 27, the meat juices transmitted from the slits 28, 28a, etc. are allowed to fall through the protrusion 31. Its practical effects are enormous.
