An embodiment of the present invention will be described with reference to the embodiment shown in FIG. 1 and FIG.

In the drawing, 1 represents a heating chamber having an entrance and exit 2 of the workpiece X on the front surface and an exhaust port 3 in the upper rear portion, and in the heating chamber 1, an upper burner installed at an upper portion thereof. (4) and each of the flame holes (a) provided at both sides of the lower side of the lower burner (5a) and the lower burner (5a) and the lower burner (5a) and the lower burner (5a) are directed toward the center of the heating chamber (1). In the center of the chamber 1, a grill 6 on which the workpiece X is placed is provided. 7 denotes a door closing the entrance 2, and 8 denotes a soup tray placed in the heating chamber 1.

In the present embodiment, when the combustion capacity of both lower burners 5a and 5b is in a strong combustion state in one burner 5a, the combustion state in which the combustion in the other burner 5b is weak is reduced. As shown in FIG. 4, the throttles 10a and 10b are respectively provided on the gas passages 9a and 9b leading to the calcination burners 5a and 5b, as shown in FIG. And a bypass passage 11 which bypasses these gas passages 9a and 9b, and connects the bypass passage 11 to the respective gas passages 9a and 9b. 12a and 12b are formed on the open / close valves 13a and 13b respectively, and the open / close valves 13a and 13b are alternately opened and closed, so that the burner on the other side when the burner on the burner 5a on the one side is in a strong combustion state. The combustion in (5b) was made to be in a weak combustion state, and as much as possible, the heat | fever was extended to the whole to-be-processed object X so that it might not burn.

In addition, in order to switch alternately at a constant time between combustion in a strong combustion state and a weak combustion state, on-off valves 13a and 13b shown in FIG. The amount of gas is changed by opening / closing the switch S1 with the rotary cam body C shown in FIG. In addition, the temporal ratio at this time is not limited to 1: 1, for example, when the strong combustion state is 5, the weak combustion state is set to 1, and the heat is evenly applied to the entire workpiece X.

In Fig. 4, reference numeral 14 denotes a fire transfer burner interposed between both fire burners 5a and 5b, 15 a fire burner interposed between the fire burner 4 and the fire burner 5a, and 16 A gas supply passage leading to the two-fire transfer burners 14 and 15, 17 is a main valve connected to the gas supply passage in common, 18a is an open / close valve for the mutual burner 4, and 18b is a fire burner 5a. (5b) is an on / off valve.

Further, in the above embodiment, when the open / close valves 13a and 13b are opened and closed alternately, when the combustion in one burner 5a is in a strong combustion state, the combustion state in which the combustion in the other burner 5b is weak is weak. Although this is repeated, the state in which the on-off valves 13a and 13b are simultaneously closed and the heat is alternately repeated so that both burners 5a and 5b are simultaneously switched to a strong combustion state and a weak combustion state. Can be spread evenly over the entire workpiece (X).

FIG. 7 shows a modification of the supply passage shown in FIG. 4, in which the throttles 10a and 10b are respectively formed in the gas passages 9a and 9b leading to the lower burners 5a and 5b. A three-way valve 19 is interposed between the bypass passage 11 and the connection passages 12a and 12b, and the bypass passage 11 is connected to the eighth (a). ), As shown in FIG. 8 (b), the combustion in the burner 5a on one side is strongly changed by switching between the state following the burner 5a on one side and the state following the burner 5b on the other side. At that time, the combustion in the lower burner 5 on the other side was brought into a weak combustion state.

In addition, when the three-way valve 19 is switched to the position as shown in FIG. 8 (c), only the fuel that has passed through the throttles 10a and 10b simultaneously supplies the fuel to the lower burners 5a and 5b. It becomes a weak combustion state.

Other configurations are not particularly different from those shown in FIG.

FIG. 9 shows an embodiment in which the ignition burners 5a and 5b can be switched to a strong combustion state at the same time and then to a weak combustion state at the same time by using a three-way valve 19 having a T-shaped passage. . To explain this, the fuel in the bypass passage 11 and the fuel passing through the throttles 10a and 10b by opening the three-way valve 19 are discharged through the gas passages 9a and 9b through the lowering burners 5a. When the fuel cell is supplied to the tank 5b, both lower burners 5a and 5b are in a strong combustion state at the same time, and only the fuel that has passed through the throttles 10a and 10b by closing the three-way valve 19 is closed. When the state is supplied to both lower burners 5a and 5b through the gas passages 9a and 9b, both lower burners 5a and 5b are in a weak combustion state at the same time. Accordingly, by switching the three-way valve 19 alternately at regular time intervals, a strong combustion state and a weak combustion state can be alternately obtained.

In addition, the air inflow to both lower burners 5a and 5b is allowed to flow only on the upper side of both lower burners 5a and 5b, and at the same time, the lower burners 5a and 5b and FIGS. If the rectifying plate 36 is formed between the lids 35 shown in the figure, and the air vent window 36a is formed at intervals on the rectifying plate 36, the heat is further increased by the air passing through the air vent window 36a. Go crazy in the middle.

In addition, the ignition in the above embodiment is performed when both lower burners 5a and 5b are in a strong combustion state. This ensures good ignition.

FIG. 10 shows another embodiment, in which the fluctuations of the flame hole burners 5a and 5b are alternately swinged up and down, so that the heat is evenly spread over the entire workpiece X. It was. To explain this, the two lower burners 5a and 5b are linked to the motor 20, respectively, so that when the burner 5a on one side is approximately horizontal, the burner 5b on the other side is obliquely downward. By shaking, the heat was spread as evenly as possible throughout the workpiece (X).

That is, when the gas fraction output from the lower burners 5a and 5b is weak, when the lower burners 5a and 5b are brought into a state close to the horizontal state, the lower burners 5a and 5b are discharged from the lower burners 5a and 5b. The flame is extended to the center position of the heating chamber 1, and when it is inclined downward, the flame heats near the side wall of the heating chamber 1. Therefore, the fluctuation burner 5a (5b) can be rocked up and down alternately, thereby making it possible to spread the heat evenly throughout the workpiece X.

In the case where the gas output from the lower burners 5a and 5b is strong, when the lower burners 5a and 5b are inclined downward, the flame from the lower burners 5a and 5b is once Since the gas is directed upward after ejecting downward, the heat reaches the center position of the heating 1 by that amount. On the contrary, when the burner burners 5a and 5b are in a state close to the horizontal state, since the hot air rises quickly from the burner burners 5a and 5b, the vicinity of the side wall of the heating chamber 1 is heated. Therefore, by burning the burners 5a and 5b alternately up and down, the heat can reach the entire workpiece X. The other configuration is not particularly different from the embodiments shown in FIGS. 1 and 2.

In the above embodiment, when the burner 5a on one side is substantially horizontal, the burner 5b on the other side is swinged up and down alternately to face downward, but this is the lower burner 5a and 5b. The same heat can be applied to the entire workpiece X even if it is rocked up and down at the same time horizontally and at the same time. In addition, the up-and-down swinging may be directed upward at an angle with the horizontal state.

The embodiment shown in FIG. 11 forms an air flow toward the center of the heating chamber 1 along the upper sides of both lower burners 5a and 4b, and alternately switches the air flow to the strength and weakness. In other words, it is to be switched between the state with and without the air flow, and when this is explained, the ducts which communicate with the air outlets 21 formed on the upper sides of both lower burners 5a and 5b, respectively, A damper for forming a fan 22 and providing one fan 23 connected to the respective ducts 22 and 22, and at the same time, dividing the blowing air from the fan 23 into the left and right air outlets 21. 24 is formed so that the dampers 24 are alternately rocked.

In this way, the air from the fan 23 is alternately supplied to the lower burners 5a and 5b by the damper 24, and when there is an air flow, the heat directed upward by the air flow is pressed to the center. When it reaches, and there is no air flow, since it does not have the said air flow, it opens to both sides as it is. Therefore, the heat can be made to spread as much as possible to the to-be-processed object X as possible.

In addition, even if the said airflow in the Example of FIG. 11 forms not only the upper side of both lowering burners 5a and 5b but the airflow which follows both the lowering burners 5a and 5b, As with one bar, the heat and heat can be evenly alternated to the center and both sides of the heating chamber (1). That is, when there is an air flow, the heat reaches the center, and when there is no air flow, the heat rises from both sides to the upper side as it is, so that the heat can be spread evenly over the entire workpiece X as possible.

In addition, a duct (not shown) communicating with each of the air outlets formed at the lower sides of the two burner burners 5a and 5b is formed, and one fan connected to each of the ducts is provided. By forming a damper that divides the blowing air from the fan into the left and right air outlets 21, and by alternately rocking the dampers, the air flow can be alternately switched to the strong and the heat can be spread evenly throughout the workpiece (X).

In addition, in the embodiment shown in FIG. 11, one fan 23 common to the duct 22 is connected, and the damper 24 is provided in the sheath, and the air from the fan 23 is blown to the right and left air outlets ( 21), but the fan 23 which communicates with the air outlet 21 of each burning burner 5a, 5b is formed, and it switches so that the air volume of each fan 23 may be left to right, or the said By switching the airflow amount of the fan 23 to the state which increased and decreased at the same time from side to side simultaneously, and generate | occur | produces a strong and weak air flow, heat can be spread | diffused evenly throughout the to-be-processed object X as much as possible.

12 and 13, air flows toward the center of the heating chamber 1 are formed along the upper sides of the two burner burners 5a and 5b, and the air flows are alternately switched to the strength. In order to explain this, the air outlet plate 25 having the plurality of air outlet ports 25a formed on both lower burners 5a and 5b is provided and along the air outlet plate 25. By installing a moving throttle plate 26 and moving the throttle plate 26 in conjunction with a motor or the like, both lower burners 5a and 5b alternately open and close the air outlet 25a. The air flow toward the middle child of the heating chamber 1 was alternately changed from side to side to strong and weak.

In this way, when the air outlet 25a becomes large and the air flow becomes strong, when the heat directed upward is pressed by the air flow to reach the center, and when the air outlet 25a becomes small and the air flow becomes weak, As the air flow is weak, heat is evenly distributed to both sides. Therefore, the heat can be spread as evenly as possible over the entire workpiece X.

In addition, although the throttle plate 26 shown to operate up and down is formed, the said throttle plate may form the through-hole for the blowout port, and may operate this to the front-back direction of a heating chamber, and may change the area of an air blowout port. In addition, even when the operation of the throttle plate 26 with respect to the left and right air outlets 25a is alternately switched between the air flows from the left and right air outlets 25a to a strong state and a weak state at the same time, the entire workpiece X Can drive crazy evenly.

In this case, the ventilation may be forced or natural ventilation by a fan.

In addition, in the above embodiment, not only the upper side of both lower burners 5a and 5b, but also the lower side, the above-mentioned which changes the air flow toward the center of the heating chamber 1 along the lower burners 5a and 5b. The same effect can be exhibited by forcibly changing the air flow toward the center of the heating chamber 1 by using such a means. In this case, ventilation is limited to forced ventilation by a fan.

In the embodiment of FIG. 14, flame holes a are respectively provided at the lower sides of the heating chamber 1, and lower burners 5a and 5b are directed toward the center of the heating chamber 1. The installation of the grill 6 on which the food X is placed is the same as in the above-described embodiment, but in this embodiment, the center of the heating chamber 1 is located along the upper side and the lower side of both lower burners 5a and 5b. In this case, the air flows toward the center of the heating chamber are formed along the upper and lower sides of both lower burners 5a and 5b. At the same time, the air outlets 27 and 27 were alternately opened and closed by a damper 28.

In this case, the opening may be set such that the opening and closing of the upper and lower sides are opposite to each other in the left and right dampers 28, or the lower side is closed so that the opening and closing of the left and right dampers 28 are the same, that is, when the upper side is opened. do.

At this time, the ventilation mimics the natural ventilation or forced ventilation by the fan.

The damper 28 may be alternately opened and closed by a motor or the like, but the damper 28 may be a shape memory alloy, and the shape memory alloy is in the heating chamber 1 when the damper 28 is closed. It is opened by the atmosphere, and in the open state, it is cooled and closed by the flow of air.

In addition, all the above-described embodiments have been described with respect to the rear exhaust-type grille having an upper burner and an exhaust port at the rear. In addition, as described above, the phenomenon that the food burns steadily occurs especially in the rear exhaust grill having the burner, but the rear exhaust grill having no burner, or the burner having the burner and the exhaust vent Central exhaust grills in the upper center of the heating chamber, or central exhaust grills without burning burners and exhaust vents in the upper center of the heating chamber may also occur. Therefore, the present invention can apply the above-described method to these grills so that food is not burned out.

In addition, in the embodiment shown to FIG. 1 thru | or FIG. 3, the exhaust path 29 extended in the horizontal direction which connects the heating chamber 1 and the exhaust port 3 to the rear of the heating chamber 1 is formed, The combustion burner 4 is extended to the exhaust passage 29, and the exhaust gas flowing through the exhaust passage 29 is burned again by the junction burner 4 to be bonded to the exhaust passage 29 so as to be odorless. In this case, the burner 4 in contact with the exhaust passage 29 may be ignited by the flame of the pilot burner 30. In this case, the pilot burner 30 is installed under the lower wall 31 of the exhaust passage 29 so as to face upward at an angle from the rear side, and is burned through the through hole 32 formed in the lower wall 31. The flame is applied to the burner 4 to be ignited. In this case, as shown in FIGS. 1 and 3, the through hole 32 is extruded obliquely upward and at the same time, when the extruded portion is formed at the upper end of the extruded portion, the through hole 32 A relatively high granular wall is formed around). Therefore, even if the soup boiled into the exhaust passage 29 or the like in the exhaust port 3 is leaked out by the granular wall formed in the through hole 32.

In the embodiment shown in FIGS. 11 to 14, the fan 23 may be stopped at the time of ignition.

15 and 16 show another embodiment, in which the heat is transferred to the workpiece X by changing the supply amount of the primary air while the gas amount of the lowering burners 5a and 5b is constant. ) To evenly spread the whole. In order to explain this, when the damper 33 is connected by using a motor M and a gear or the like, and the damper 33 is opened to increase the supply amount of the primary air, the flame becomes longer in the direction toward the flame hole. The hot air reaches the center of the heating chamber 1, and when the damper 33 is closed to accumulate the supply amount of the primary air, the flame rises, so the hot air is directed to both sides of the heating chamber 1. Therefore, by opening and closing the damper 33 slowly and repeatedly by the motor M, the heat can be spread evenly over the entire object X.

It is also possible to switch the supply amount of the primary air by switching the air flow rate of the blower instead of the damper 33 in the above embodiment. In addition, the cooking mode can be changed to strong or weak depending on the cooking. This ultimately increases or decreases the gas amount, and thus the primary air is somewhat changed in response to the gas amount in the grill which increases or decreases the gas amount.

In addition, it is required to switch the cooking mode even in the grill in which the two lower burners 5a and 5b are alternately switched between a strong combustion state and a weak combustion state. To satisfy this, the steel cooking mode has a long burning time in a strong combustion state and a short burning time in a weak combustion state, and a long burning time in a weak combustion state with a short burning time in a strong combustion state. (Iii) Switch to cooking mode.

This will be explained based on FIG. 17 to the enhanced mode mode A and the cam plate C connected to the contacts on one side of the micro switch S1 switched by the cam plate C shown in FIG. For example, of the solenoid valves 13a and 13b shown in FIG. 4 through the manual switch S2 for selecting the weak cooking mode circuit B connected to the contact of the other side of the micro switch S1 switched by The coils 13a-1 and 13b-1 are connected to the power source W.

The cam plate C is, for example, connected to the high combustion mode circuit A side for 50 seconds and to the low combustion mode circuit B side for 10 seconds.

In this way, when the highlighted mode circuit A is selected by the manual switch S2, the coil 13a-1 and 13b-1 of the solenoid valves 13a and 13b are energized for 50 seconds to supply the solenoid valve ( 13a and 13b are opened to burn both burners 5a and 5b in a strong combustion state, and the coils 13a-1 and 13b-1 of the solenoid valves 13a and 13b for the next 10 seconds. The combustion of the furnace is repeated and the combustion key is repeatedly changed to a weak combustion state. Therefore, the amount of combustion gas in the lowering burners 5a and 5b in one cycle becomes relatively large. On the contrary, when the weak combustion mode circuit B is selected by the manual switch S2, the solenoid valve is disconnected from the solenoid valves 13a and 13b by energizing the coils 13a-1 and 13b-1 for 50 seconds. (13a) (13b) is closed to burn both burners (5a) and (5b) in a weak combustion state, and the coils (13a-1) and (13b-1) of the solenoid valves (13a) and (13b) for the next 10 seconds. ), Alternating with and burning with strong combustion state. Therefore, the amount of combustion gas in both lowering burners 5a and 5b in one cycle is relatively small. The switching means may be controlled by a microcomputer.

In addition, in the grill provided with the burning burner 4, the cooking mode can be further increased by combining the switching of the cooking mode with the ignition and extinguishing of the burning burner 4.

Thus, in the grill provided with an upper burner and a lower burner, especially in the case of the surface combustion type which used the ceramic burner as an upper burner, the upper burner may not ignite by exhaust of the lower burner. In this case, in Fig. 4, first, the open / close valve 18a is opened to ignite the burner, and when the flame detection means (not shown) confirms the ignition, the open / close valve 18b may be opened to ignite the lower burner.

Further, a means for swinging the flame hole side of both lower burners 5a and 5b up and down in switching between the strong and weak combustion states of both lower burners 5a and 5b, or the both lower burners ( Means for forming an air flow toward the center of the heating chamber 1 along 5a) and 5b, and for switching the air flow to the strength or the heating chamber along the upper and lower sides of both lower burners 5a and 5b. The means which alternately forms the air flow toward the center of (1) up and down can be used together.

In addition, the means for swinging the flame hole side of the lower burner 5a, 5b up and down in varying the supply amount of the primary air to the lower burner 5a, 5b, or the lower burner 5a. Means for forming an air flow toward the center of the heating chamber 1 along 5b, and for switching the air flow to the strength or weakness, or the heating chamber 1 along the upper and lower sides of both lower burners 5a and 5b. The means which alternately forms the air flow toward the center of) up and down can be used together.

In the grill provided with the above structure, the following effects are obtained.

In the grill according to claim 1 having the above-described structure, since the heat spreads to the center position of the heating chamber when the burning burner is in a strong combustion state, and the heat burner is near the side wall of the heating chamber when the burning burner is in a weak combustion state, the burning burner It is possible to spread the heat evenly over the whole of the cooked food by simply switching the combustion capacity of the burner. Therefore, the heat of the ignition burner that is in contact with the cooked food is generally uniform, so that the food can be baked evenly throughout.

In the grill according to claim 2, since the flame hole side of both lower burners is swung up and down, the heat from the lower burners can reach both the side walls of the heating chamber and the center of the heating chamber. Heat can be spread evenly throughout the creation.

In the grill according to claim 3, the air flows toward the center of the heating chamber along the both lower burners, and the air flow is switched to the strength and weakness, so that the heat from both lower burners is heated to the air chamber. The heat from both sinter burners can be spread evenly over the whole to be cooked because it can be directed to both side wall side and the center side of the heating chamber.

In the grill according to claim 4, when the air flow toward the center of the heating chamber is formed along the upper side of the calcining burner, the heat from the calcining burner is increased by the air flow to face the center of the heating chamber. Even when air flows toward the center of the heating chamber along the lower side of the lower burner, heat from the lower burner is directed toward the wall side of the heating chamber by the air flow. Thus, by repeating this alternately, the heat can be spread evenly over almost all of the workpiece placed on the grill.

In the grill according to claim 5, when the supply amount of primary air to both lower burners is increased, the heat reaches the center of the heating chamber by the length of the flame hole of the flame from both lower burners. When the supply amount of the primary air is reduced by closing the damper, the flame rises so that the heat is directed to both sides of the heating chamber. Therefore, by repeating this alternately, the heat can be spread evenly over almost all of the workpiece placed on the grill.

In the grill according to claim 6, the heat is uniformly spread over the whole to be cooked by alternately switching the burning capacity of the calcined burner, and the food is uniformed throughout the whole by making the heat of the calcined burner in contact with the cooked material almost uniform. In the grill which can be baked easily, the cooking mode can be switched, so that cooking under different calories can be performed.
