Description

  The present invention relates to a stove using a burner that uses gas, petroleum, or the like as fuel as a heating source.

Conventionally, there is such a stove as shown in Patent Document 1. As shown in FIG. 10, this is a ceiling provided with an opening 73 corresponding to the annular burner 72 above the annular burner 72 in which a large number of inward flame ports 71 are arranged in the circumferential direction of the inner surface. The first air passage is formed by placing the plate 74 and placing the virtuosity frame 75 having an opening diameter enough to cover the annular burner 72 through the gap 76 in order to prevent the boiling from being applied to the annular burner 72. 77, a second air passage 78 is provided below the annular burner 72, and a detachable juice tray 79 is placed directly below the annular burner 72. A downward gallery is provided above the circumferential surface portion of the juice tray 79. A plurality of third air passages 80 are provided, and the pan 81 is heated by bringing the flame 81 formed inward from the flame port 71 of the annular burner 72 toward the center.
Japanese Utility Model Publication No. 6-40705

  However, in the case of the above-described conventional stove, the soup pan 79 is detachable, and when the soup pan 79 becomes dirty due to falling of boiled juice or the like, the user may normally remove the soup pan 79 for washing the soup pan 79. . And it is a normal usage method that the soup pan 79 is mounted again after washing and the stove is reused. Further, the flame 81 formed inward by the annular burner 72 is assumed to be normally attached to the soup pan 79, and flows into the first air passage 77, the second air passage 78, and the third air passage 80. It is maintained by the balance of the combustion air volume. However, as shown in FIG. 11, if the user forgets to wear the juice pan 79 or loses it for some reason, the third air passage 80 of the juice pan 79 is originally kept at a constant opening area. The open space 82 has an excessive opening area, and a large amount of air flows from the lower side of the annular burner 72. Due to this, the amount of combustion air from the first air passage 77 decreases, so As a result, the flame 83 comes into contact with the inner peripheral portion of the virtuosity frame 75 and burns outward while heating it. Further, when the combustion amount is reduced in this state, the combustion air amount from the first air passage 77 is further reduced, so that the small flame 84 is placed in the gap 76 between the annular burner 72 and the five virtue frames 75. There was also a problem that the temperature inside the stove body rose due to the inflow and the combustion exhaust flow.

  The present invention solves the above-described conventional problems, regardless of whether or not the soup pan is attached, maintains the balance of the amount of combustion air around the burner optimally and maintains the state where the flame is brought to the center, An object of the present invention is to provide a stove that can prevent high temperature around the stove and inside the main body while ensuring high thermal efficiency.

  In order to solve the above-described conventional problems, a stove according to the present invention includes a top plate provided with a first opening, a substantially annular burner provided inside the top plate and having a flame opening formed in an inner peripheral surface thereof. A substantially annular rectifier body which is provided above the burner via a gap and which forms an upper inclined part on the inner peripheral side, and a burner base which is provided below the burner and which forms a second opening part directly below the first opening part, A main body plate provided below the burner base and a detachable juice receiving tray placed in the second opening are provided, and a shielding body for shielding between the second opening and the main body plate is provided.

  As a result, the first air flow is generated from the outside to the inside in the gap between the rectifier and the burner due to the negative pressure generated when the flame of the annular burner is ejected toward the center. It spreads to the center of the flame and keeps the direction of the flame further toward the center while suppressing upward flame. In addition, a second air flow is generated from the space between the burner and the burner stand and diffused into the flame, and the balance between the inflow direction and the inflow amount of the first air flow and the second air flow is maintained appropriately. After the flame rises and passes through the space formed inside the rectifier, it diffuses into the outside air along the surrounding shape. Therefore, the flame can be concentrated in the center while maintaining a good combustion state, and the heat receiving area of the pan can be expanded, so that high thermal efficiency can be ensured.

  On the other hand, when the soup pan is soiled due to boiling or the like, the user takes it out through the first opening of the top plate and performs a cleaning operation. At this time, even when the user does not attach the soup pan to the burner base for some reason and the burner is ignited and the stove is used, the shield that shields between the second opening of the burner base and the main body plate is In order to suppress a large amount of air from flowing in between the two openings and the main body plate, the balance between the first air flow and the second air flow can be maintained appropriately, and as a result, the flame can be kept concentrated in the center. Therefore, regardless of whether or not the soup pan is attached, the direction of the flame can be properly maintained to ensure high thermal efficiency, and at the same time, the surroundings of the stove and the inside of the main body can be prevented from being heated.

  The stove of the present invention maintains the state in which the flame is brought to the center by maintaining the balance of the inflow direction and the inflow amount of the combustion air around the annular burner regardless of whether or not the soup pan is attached. While ensuring high thermal efficiency, it is possible to prevent the inside of the stove body from becoming hot.

(Embodiment 1)
FIG. 1 is a vertical cross-sectional view of a main part of a stove according to Embodiment 1 of the present invention, and FIG. 2 is a vertical cross-sectional view of a main part of the stove in a state where a juice receiving tray is not attached in the same embodiment.

  1 and 2, the burner 1 is a sheet metal material having a thickness of 0.5 to 1 mm that has excellent heat resistance and corrosion resistance, such as austenitic stainless steel such as SUS304, SUS316, and SUS321, or ferritic stainless steel such as SUS430 and SUS436. In the case of the present embodiment, 0.5 to 0.6 mm) is press-molded, and the annular tube 2 and the mixing tube 3 for sucking the premixed gas are communicated in the substantially tangential direction of the annular tube 2. It is a thing. The annular tube 2 and the mixing tube 3 are formed by fitting a bottom plate 5 having an annular inner periphery in the same manner as the flame port plate 4 having an annular inner periphery. An inner peripheral flange portion 7 is formed on an annular inclined surface 6 inclined upward to an extent and an inner peripheral portion below the annular inclined surface 6. Further, the inclined surface 6 is provided with a flame opening portion 8 having a slit width of about 0.55 to 0.65 mm and having a plurality of slits opened vertically in the vertical direction. On the other hand, the bottom plate 5 has a shape corresponding to the flame opening plate 4, the outer peripheral portion of the burner 1 is covered and fitted by the outer peripheral fitting portion 9, and the inner peripheral portion is inclined obliquely downwardly. 10 is covered and fitted. Further, the flame opening 8 is provided at a certain distance from the upper end of the inclined surface 6, and between the long slit groups 11 composed of two rows, the short slit groups 12 composed of two rows or four rows, The shortest slit group 13 consisting of five rows is arranged in combination.

  On the other hand, in the first opening 15 of the top plate 14 made of heat-resistant tempered glass, five virtues 18 in which six claw parts 17 are fitted to an annular frame 16 are installed, and the claw parts 17 are the shortest slit group. A burner 1 is disposed so as to be located immediately above the center of 13. Above the burner 1, a rectifying body 22 that constitutes an upper inclined portion 20 on the inner peripheral side and a lower inclined portion 21 on the outer peripheral side via a gap 19 is provided, and an inner peripheral end portion of the upper inclined portion 20 is It is shielded by the inner peripheral edge of the frame 16 of the five virtues 18. Further, below the burner 1, there is provided a burner base 25 in which a second opening 23 corresponding to the first opening is formed at the center, and a juice receiving tray 24 is placed on the peripheral edge of the second opening 23. A main body plate 26 of the stove main body is provided below the burner base 25. Here, an air passage 27 communicating with the outside air is formed between the burner 1 and the burner base 25, and a cylindrical shield 28 is formed around the second opening 23 toward the main body plate 26 side. Yes. In the case of the present embodiment, the shield 28 is configured integrally with the burner base 25 as a downward bent portion 29 around the second opening 23 of the burner base 25 by pressing, and the lower end portion of the downward bent portion 29 is the main body. It is in contact with or very close to the plate 26. Further, the juice receiving tray 24 is configured to have a size smaller than the diameter of the inner peripheral portion of the frame 16 of the five virtues 18 and can be taken out of the top plate 14 through the inner space of the burner 1.

  The operation and action of the stove configured as described above will be described below.

  First, since the flame opening 8 in the burner 1 is formed by a narrow slit having a slit width in the range of 0.55 to 0.65 mm, the premixed air ratio that is normally set in the burner for the stove is 40 to 50%. Even in the case of a higher premixed air ratio (for example, 60 to 80%), it is difficult to backfire. Incidentally, the burner 1 is made of a stainless steel plate having excellent heat and corrosion resistance, so that the slit width of the flame opening 8 can be punched in a range of 0.8 to 1.2 times the plate thickness. Depending on the plate thickness, the degree of freedom in selecting the shape of the flame mouth can be expanded. For this reason, even in the case of a fuel with a high combustion speed such as a mixture of hydrogen and air, it is easy to prevent backfire by optimizing the plate thickness and slit width of the burner 1. In the case of the present embodiment, a stainless steel plate having a thickness of 0.5 to 0.6 mm is used, and the premixed air ratio is set to 65 to 70%. Thus, the premixed gas with a high premixed air ratio can be introduced, and the obliquely upward flame 30 formed toward the center at the flame opening 8 has a relatively short flame length. Further, since the flame opening 8 is formed on the inclined surface 6 inclined obliquely upward toward the center, the ejection angle of the flame 30 can be directed obliquely upward, and the inner peripheral diameter of the flame opening 8 is upward. Since the distance between the slits 30 is increased, the distance between the flames 30 in each flame opening can be increased to reduce mutual interference, and the heat radiation to the upper side of the inclined surface 6 is improved, so that the flame mouth portion. The temperature rise of 8 can be suppressed. At this time, in the gap 19 between the rectifying body 22 and the burner 1, the negative pressure due to the rising air current of the flame 30, the height of the lower end portion of the downward inclined portion 21 of the rectifying body 22 and the inner peripheral end portion of the rectifying body 22 are increased. Due to the chimney effect caused by the difference, a first air flow 31 directed toward the flame 30 is generated in the gap 19, and the flame 30 rises while concentrating on the center as the combustion is promoted, and comes into contact with the bottom of the pan and diffuses. Also, below the burner 1, a second air flow 32 generated by the updraft of the flame 30 is generated through the air passage 27 of the burner base 25, but the slits are arranged vertically in the vertical direction and are adjacent to each other. The second air flow 32 can be effectively introduced between the slits. Further, the configuration in which the short slit group 12 and the shortest slit group 13 are disposed between the long slit groups 11 suppresses interference between the flames 30 formed by the long slit group 11. Thus, the flame 30 is divided to realize a short flame, and the fire transfer between the long slit groups 11 can be improved. In this way, the first air flow 31 and the second air flow 32 maintain an optimal balance and effectively diffuse into the flame 30 to maintain good combustion.

  Furthermore, since the claw portion 17 of the virtues 18 is arranged so as to be located immediately above the center of the shortest slit group 13, the shortest flame formed by the shortest slit group 13 is located directly below the claw portion 17. Therefore, even if the distance between the claw part 17 and the burner 1 is shortened, the generation of unburned gas such as CO due to the contact between the claw part 17 and the flame 30 is achieved. And overheating of the claw portion 17 can be prevented, and the durability of the five virtues can be improved and high thermal efficiency can be ensured.

  On the other hand, when a pan or the like is heated by the burner 1, the contents in the pan boil over time, and occasionally spills may be generated and accumulated in the juice tray 24. In such a case, the user takes out the normal juice receiving tray 24 and performs cleaning. At this time, for some reason, it may happen that the juice receiving tray 24 after washing is forgotten to be attached to the second opening 23 of the burner base 25 or the juice receiving tray 24 itself is lost. As shown in FIG. 2, a case where the stove is used without the juice receiving tray 24 occurs. At this time, around the second opening 23 of the burner base 25, a cylindrical shield 28 directed toward the main body plate 26 is integrally formed as a lower bent portion 29, and the lower end of the lower bent portion 29 is the main body plate. 26, it is in a state where it is in contact with or very close to 26, so even if the burner 1 is ignited, there is almost no air inflow from the second opening 23, and the first air flow 31 and the second air flow 32 are As in the case where the soup pan 24 is mounted, the optimal balance can be maintained and the outflow direction and the combustion state of the flame 30 can be maintained well.

  As described above, regardless of whether or not the soup pan 24 is attached, the state in which the flame 30 in the burner 1 is moved to the center is maintained to ensure high thermal efficiency, and at the same time, the temperature around the stove and inside the main body is increased. Can be prevented.

It is a control flowchart of the fuel supply means in the form.

  In FIG. 3, the difference from the first embodiment is that the shielding body is not formed around the second opening 41 of the burner base 40, and a specific position around the second opening 41 on which the juice receiving tray 24 is placed. In addition, the attachment / detachment detection means 42 of the juice receiving tray 24 incorporating the switch configuration is provided, the attachment / detachment detection means 42 and the fuel supply means 43 are interlocked, and the fuel supply means 43 is stopped when the juice receiving tray 24 is not attached. By the way.

  Note that components having the same reference numerals as those in Embodiment 1 have the same structure, and description thereof is omitted.

  About the stove comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIG. 3, when the stove is used in a normal state where the juice receiving tray 24 is mounted, the switch configuration of the attachment / detachment detecting means 42 is in a connected state due to the weight of the juice receiving tray, and the juice as shown in FIG. By detecting that the receiving tray 24 is mounted and determining that it is in a normal state and sending the detection signal to the fuel supply means 43, fuel is supplied from the fuel supply means 43 to the burner 1, and the embodiment is described. The center-side flame 30 similar to 1 is formed. On the other hand, as shown in FIG. 4, when the juice receiving tray 24 is not attached for some reason, the switch configuration of the attachment / detachment detection means 42 is disconnected and it is detected that the juice receiving tray 24 is not attached. As shown, the fuel supply from the fuel supply means 43 is stopped by the detection signal. Therefore, the burner 1 is not ignited, and normally, by combining with various notification means, the user is notified that the burner 1 is not lit because the juice receiving tray 24 is not attached, and the juice receiving tray 24 is mounted. Can be encouraged. Accordingly, since the burner 1 is not ignited when the soup pan 24 is not attached, combustion in the burner 1 when the soup pan 24 is not attached is prevented in advance, and the situation is immediately notified to the user. In addition, the temperature around the stove and in the main body can be prevented. In a normal combustion state, high thermal efficiency can be ensured.

(Embodiment 3)
FIG. 6 is a longitudinal sectional view of the main part of the stove according to Embodiment 3 of the present invention, FIG. 7 is a longitudinal sectional view of the main part of the stove with the juice receiving tray not attached in the same embodiment, and FIG. It is a control flowchart of the fuel supply means in the form.

  In FIG. 6, the difference from the first embodiment is that a temperature switch that faces the rectifier 52 in the gap 19 between the burner 1 without forming a shield around the second opening 51 of the burner base 50, etc. The temperature detecting means 53 configured as described above is provided, the temperature detecting means 53 and the fuel supply means 54 are interlocked, and the fuel supply means 54 is stopped when the atmospheric temperature in the gap 19 reaches a certain set temperature. .

  Note that components having the same reference numerals as those in Embodiment 1 have the same structure, and description thereof is omitted.

  About the stove comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  As shown in FIG. 6, when the stove is used in a normal state where the soup pan 24 is mounted, the first air flow 31 and the second air flow 32 maintain an optimal balance, and the flame 30 of the burner 1 Effectively diffuse to maintain good combustion. Therefore, the atmospheric temperature in the gap 19 is in a state that does not reach the set temperature (T <T1 ° C.). In such a case, as shown in FIG. 8, the fuel is continuously supplied from the fuel supply means 54 to the burner 1. However, as shown in FIG. 7, in a state where the juice receiving tray 24 is not mounted on the second opening 51, a large amount is passed through the second opening 51 from the space between the main body plate 26 and the burner base 50. While the third air flow 56 flows in as an updraft, the inflows of the first air flow 57 and the second air flow 58 are greatly reduced, and as a result, the burner 1 greatly spreads to the outer peripheral side. A flame 55 is formed, and the flame 55 approaches or comes into contact with the inner peripheral end of the rectifying body 52 or the inner peripheral end of the frame 16 of Gotoku 18, and the rectifying body 52, the frame 16 and the like are overheated, inevitably. The atmospheric temperature in the gap 19 rises rapidly. At this time, as shown in FIG. 8, when the temperature detection means 53 detects that the temperature is equal to or higher than the set temperature (T ≧ T1 ° C.), the connection state of the temperature switch of the temperature detection means 53 is released, and the detection signal indicates The fuel supply means 54 stops the fuel supply to the burner 1. Therefore, the burner 1 is put into a fire extinguisher state, and is usually in combination with various informing means to notify the user that the burner 1 has been extinguished because the soup pan 24 is not attached, and the soup pan 24 is attached. Can be urged. Further, even when the soup pan 24 is normally mounted, the combustion gas is not easily discharged from the first opening 15 in an abnormal state where the first opening 15 is blocked or the opening area is narrowed. Thus, the balance of the air flow around the burner 1 is lost, and high-temperature combustion gas flows out toward the outer circumferential direction in the gap 19, so that the ambient temperature in the gap 19 also rises rapidly. Even in this case, the temperature detection means 53 reaches the set temperature, the connection state of the temperature switch of the temperature detection means 53 is released, and the fuel supply means 54 stops the fuel supply to the burner 1. In this way, regardless of whether or not the soup pan is attached, even if various combustion abnormalities occur in the burner 1, the situation is promptly notified to the user, and the temperature around the stove and in the main body is prevented. Can do. In a normal combustion state, high thermal efficiency can be ensured.
