Description

  The present invention relates to a relatively small heating device that is installed in a heating unit of the virtues so as to be freely inserted and removed and used to heat a pan or the like placed on the virtues by burning liquid fuel.

  Conventionally, for example, a relatively small Gotoku has been used to provide small hot pot dishes at an inn or a restaurant. Such a virtuosity heating device is usually constituted by a solid fuel obtained by solidifying a combustible wax in a cylindrical shape. When solid fuel is ignited in a state where it is installed in the heating section of Gotoku, it burns while vaporizing wax.

JP 2004-166732 A

  Conventional solid fuels are not suitable as a heating device for cooking food because they emit smoke and soot caused by incomplete combustion during combustion and generate malodor. In addition, after the start of combustion, it is gradually consumed from above and the height is lowered, so that there is a problem that the position of the flame gradually decreases and the heating power against the pan bottom becomes weak.

  An object of the present invention is to solve the above problem by providing a clean heating device using a liquid fuel such as alcohol instead of a conventional solid fuel.

  By the way, in order to provide a heating device using liquid fuel, for example, a heating device as shown in FIG. 6 can be assumed. As shown in FIG. 6A, the heating device 1 of this conceivable comparative example stores liquid fuel 4 in a container 3 having an opening 2 in the upper part. Therefore, the vaporized gas of the liquid fuel rising from the opening 2 can be burned. At this time, the liquid fuel such as alcohol is burned completely satisfactorily, so that it does not give off odor and odor like conventional solid fuel. In addition, the heating power is constant, desired cooking can be performed, and even when the liquid fuel in the container is consumed and insufficient, the liquid fuel can be easily and easily added.

  However, according to the knowledge of the present inventors, conventional solid fuel is combusted while passively liquefying and solidifying the solid fuel little by little according to combustion, whereas liquid fuel such as alcohol is used. In the case of the heating device 1, since the liquid fuel actively vaporizes and raises the vaporized gas, the flame 6 diffuses around as shown in FIG. 6C, and the pan 8 placed on the upper part of the virtues 7 The firepower on the bottom of is not always sufficient. And if heating power is strengthened by increasing the rising amount of vaporized gas, since the food in a pot will continue to be heated by strong heating power even after being cooked early, there is a problem that the food will be overheated. In addition, since the liquid fuel 4 is stored in the container 3, if the liquid fuel 4 falls down during combustion, the liquid fuel 4 overflows, resulting in an extremely dangerous state.

  The present invention provides a heating apparatus that uses a liquid fuel to enable a sufficiently strong heating power and to reduce the heating power as necessary, thereby enabling a heat-retaining state with a low heat.

  Therefore, the present invention is configured as a means, which is a heating device that is installed freely in and out of the heating unit of Gotoku, constituting a container body having a storage chamber for storing liquid fuel, and the storage chamber of the container body Includes a thick impregnation layer disposed at least at the bottom of the storage chamber so as to impregnate the liquid fuel, and a porous ceramic body loaded on the impregnation layer. A plurality of passages extending in the vertical direction are provided so as to allow the combustion gas to pass therethrough, and an opening portion of the storage chamber is formed above the ceramic body in the upper portion of the container body, and extends upward with a predetermined diameter. A diffusion prevention means having an annular wall is provided.

  The diffusion preventing means is preferably provided with a control means that can reduce the opening diameter of the opening of the annular wall.

  The conventional solid fuel emits burnt odors and odors, and gradually lowers the position of the flame to weaken the thermal power. On the other hand, according to the present invention, the vaporized gas rising from the liquid fuel such as alcohol is burned. Therefore, there is an effect that the fuel can be used repeatedly by adding liquid fuel even after the fuel is consumed, since the firepower is constant and the fuel power is constant.

 In particular, according to the present invention, the impregnation layers 18a and 18b housed in the storage chambers 17a and 17b of the container bodies 12a and 12b are impregnated with the liquid fuel. However, there is no danger that the liquid fuel overflows from the container main bodies 12a and 12b, and it can be used safely.

  By the way, when directly evaporating the gas vapor of the liquid fuel rising from the nonwoven impregnated layer, the present invention has a problem that the surface of the nonwoven fabric is burnt and fouled or generates a strange odor. Since the vaporized gas is raised through the porous ceramic bodies 21a and 21b laminated on the layers 18a and 18b and burned through the openings 23a and 23b provided above the ceramic bodies, it is always clean. In addition, odorless clean combustion is possible. Since the porous ceramic bodies 21a and 21b are interposed, the amount of vaporized gas generated can be controlled so that an appropriate heating power can be obtained by impregnating the ceramic body itself with liquid fuel. In addition, it is possible to add many functions and effects such as making the ceramic material excellent in antibacterial and deodorizing properties.

  At this time, in the present invention, the ceramic bodies 21a and 21b are provided with a plurality of passages 22a and 22b extending in the vertical direction, so that a sufficient amount of vaporized gas can be generated with a large surface area, and the flame 15a having a strong thermal power is produced. , 15b can be formed. At this time, if the passages 22a and 22b are formed so as to penetrate up and down the ceramic bodies 21a and 21b, the liquid fuel is generated by raising the internal air of the passages 22a and 22b in accordance with the negative pressure by the upper flames 15a and 15b. Vaporization can be promoted, and vaporized gas from the impregnated layers 18a and 18b located at the bottom can be added to the flames 15a and 15b through the passages 22a and 22b. Can be.

  Moreover, according to the present invention, the annular walls 24a and 24b forming the openings 23a and 23b are extended upward above the ceramic bodies 21a and 21b, thereby constituting the diffusion preventing means 13a and 13b. Therefore, it is possible to prevent the vaporized gas of the rising liquid fuel from diffusing to the surroundings, and to form strong fired flames 15a and 15b that are converged.

  And since the control means 16a and 16b which can reduce the opening diameter of the opening parts 23a and 23b are provided, after to-be-heated bodies, such as a pan, are heated enough and necessary by heating apparatus 10a, 10b, control is carried out. By means 16a, 16b, the amount of vaporized gas can be suppressed, the flames 15a, 15b can be made smaller and the heating power can be weakened, overheating of the heated object can be prevented, and heating in a heat-retaining state can be achieved.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the heating device 10 constitutes a container body 12 that is installed in a heating part of the virtues 11 so as to be freely inserted and removed, and stores liquid fuel such as alcohol in a storage chamber of the container body 12. On the upper part of the container body 12, a diffusion preventing means 13 having an annular wall that forms an opening is provided. FIG. 1A shows a state where the pan 14 placed on the virtues 11 is heated by the heating device 10, and the vaporized gas of the liquid fuel rising from the opening of the container body 12 is surrounded by the diffusion preventing means 13. The flame 15 which is converged so as not to diffuse into the gas and formed by the combustion of the vaporized gas is directed to the bottom of the pan 14, and the pan 14 is suitably heated.

  The diffusion preventing means 13 is provided with a control means 16 that can reduce the opening diameter of the opening of the annular wall. Therefore, after the pan 14 is heated as much as necessary and the food is cooked, as shown in FIG. 1 (B), the flame 15 is reduced by the control means 16 to weaken the heating power, and the pan 14 is kept warm. Can be maintained.

  Hereinafter, the heating device 10a according to the first embodiment will be described with reference to FIGS. 2 and 3, and the heating device 10b according to the second embodiment will be described with reference to FIGS. 4 and 5.

(First embodiment)
In the heating apparatus 10a shown in FIGS. 2 and 3, the container body 12a is configured such that a thick impregnation layer 18a is disposed on the bottom and periphery of the storage chamber 17a, and the impregnation layer 18a is impregnated with a liquid fuel such as alcohol. is doing. The impregnation layer 18a is formed of, for example, a nonwoven fabric and stores a necessary and sufficient amount of liquid fuel in an impregnated state. In the case of the illustrated example, the bottom wall 19a and the peripheral wall 20a are formed by the non-woven fabric so as to be disposed at the bottom and the peripheral portion of the storage chamber 17a, but may be configured as a disk-like body having only the bottom wall 19a. . The non-woven fabric constituting the impregnated layer 18a is inexpensive if recycled felt waste is used.

  A ceramic body 21a is loaded on the impregnation layer 18a. The ceramic body 21a is made of porous ceramic and impregnated with liquid fuel. At this time, the amount of impregnation per predetermined volume is designed such that the amount of M is greater than the amount of m, where the amount of impregnation layer 18a is M and the amount of ceramic body 21a is m. In the case of the illustrated example, the bottom and outer peripheral parts of the ceramic body 21a are held by the impregnation layer 18a, so that an appropriate amount of liquid fuel impregnated and stored in the impregnation layer 18a is directed from the bottom and outer peripheral parts of the ceramic body 21a to the inside. Impregnated. The ceramic body 21a is provided with a number of passages 22a extending in the vertical direction. In the case of the illustrated example, the passage 22a is formed so as to penetrate up and down the ceramic body 21a, but the bottom may be formed blind. The number of passages 22a is not limited, but at least two or more are formed.

The ceramic material of the ceramic body 21a is excellent in antibacterial and deodorizing properties by containing a photocatalyst such as titanium oxide (TiO ₂ ), and is a special porous ceramic fired so as not to be too hard and not too soft. Configure.

  Diffusion provided with an annular wall 24a having a predetermined diameter and an upward opening 23a of the storage chamber 17a is formed above the ceramic body 21a in the upper part of the container body 12a having the impregnated layer 18a and the ceramic body 21a. Preventing means 13a is provided. In the case of the illustrated example, the diffusion preventing means 13a is formed by standing an annular wall 24a on an annular plate 26a fixed to the upper opening edge of the container body 12a. At this time, the inner diameter of the opening 23a is preferably formed to be substantially the same as the outer diameter of the ceramic body 21a or slightly smaller than the outer diameter of the ceramic body 21a as illustrated. The container body 12a, the annular plate 26a, and the annular wall 24a are preferably made entirely of metal.

  As shown in FIG. 2A, a removable cap 27a is attached to the annular wall 24a, and the opening 23a is covered. The cap 27a is made of a flexible synthetic resin, has a flange 28a on the outer periphery of the plug portion fitted into the opening 23a, and has a pull ring 29a on the upper surface.

  The heating device 10a is provided with control means 16a that is separate from the container body 12a. The control means 16a is provided with a downward saddle-shaped crown portion 31a that can be crowned from above the annular wall 24a, and a handle 30a that extends outward from the crown portion 31a, and has a small diameter on the top surface of the crown portion 31a. Opening 32a is opened. The inner diameter of the small diameter opening 32a is smaller than the inner diameter of the opening 23a of the annular wall 24a. For example, the diameter of the small diameter opening 32a with respect to the diameter of the opening 23a is in the range of 40% to 60%. Preferably, it is formed to be in the range of about 45% to 55%. The control means 15a is preferably connected to the container body 12a by the anchoring means 33a such as a chain.

  As shown in FIG. 2 (A), the heating device 10a according to the first embodiment injects liquid fuel such as alcohol from the opening 23a into the storage chamber 17a and sufficiently impregnates the impregnation layer 18a. It is stored by attaching 27a.

  Therefore, when using the heating device 10a, as shown in FIG. 2 (B), the cap 27a is removed and the opening 23a is opened, and the heating device 10a is installed in the heating unit of the five virtues 11 as shown in FIG. The liquid fuel vapor rising from the opening 23a is ignited to burn and form a flame 15a. The liquid fuel impregnated in the impregnation layer 18a is impregnated in the porous ceramic body 21a, and vaporized gas generated on the surface of the ceramic body 21a is raised from the opening 23a. At this time, since a large number of passages 22a are formed in the ceramic body 21a, a sufficient amount of vaporized gas is generated by a large surface area to form a flame 15a having a strong heating power. In particular, since the internal air is pulled up from the multiple passages 22a due to the negative pressure generated in the portion of the flame 15a, the vaporization and suction of the liquid fuel is promoted. In this regard, if the passage 22a is formed so as to penetrate up and down as shown in the figure, the portion of the liquid fuel impregnated in the impregnated layer 18a is vaporized toward the passage 22a and vaporizes toward the passage 22a. Since it passes through 22a and is added to the flame 15a, the thermal power becomes stronger.

  At this time, as described above, the ceramic body 21a is excellent in antibacterial properties and deodorizing properties, so that a clean, odorless and clean flame 15a is formed.

  During combustion, the vaporized gas of the liquid fuel rising from the ceramic body 21a through the opening 23a is restrained by the annular wall 24a of the diffusion preventing means 13a, so that it is prevented from diffusing around. As shown in FIG. 1 (A), a converged strong fire flame 15a is formed. And after a combustion start, a thermal power is constant and does not reduce a thermal power gradually like a solid fuel.

  Also, even if it falls over during combustion, the liquid fuel is impregnated in the impregnated layer 18a and does not overflow from the container body 12a, which is safe. When the liquid fuel is consumed and deficient during or after use, the liquid fuel can be easily and easily added from the opening 23a to the storage chamber 17a and repeatedly used.

  By the way, after the to-be-heated body such as the pan 14 is sufficiently and sufficiently heated by the heating device 10a, the crown portion 31a of the control means 16a is crowned on the annular wall 24a as shown in FIG. Thereby, since the opening 23a is reduced in diameter by the small-diameter opening 32a, the rising amount of the vaporized gas of the liquid fuel is suppressed, the flame 15a is reduced and the heating power is weakened, as shown in FIG. Allow heat insulation. Such crowning operation of the control means 16a can be performed from the outside of the virtues 11 by the handle 30a.

The knobs 40b, 40b provided at the tail ends of both arms are mutually connected. By operating in the proximity direction or the separation direction, both arms 38b, 38b are rotated in the direction of proximity or separation. At this time, the arms 38b and 38b form arc edges that oppose each other, and the variable opening 41b formed between the arc edges can be reduced in diameter and increased in diameter. The diameter D of the variable opening 41b is the same as or larger than the diameter d of the opening 23b and the upper opening 36b when the arms 38b and 38b are opened, and when the arms 38b and 38b are closed. The opening 23b and the upper opening 36b are formed to have a diameter smaller than the diameter d, that is, the diameter D with respect to the diameter d is in the range of 40% to 60%, preferably in the range of about 45% to 55%. Yes. Alternatively, the opening 23b may be closed by completely closing the arms 38b and 38b so as to overlap each other.
