Description

[Technical Field]

[0001] The present invention relates to a heating device. [Background Art]

[0002] In a radiation-type heating device (a so-called kerosene stove) that burns fuel (kerosene) in a combustion section to heat a red-hot element and radiates infrared rays from the red-hot element into a room, a glass cylindrical outer cylinder is disposed in a radiation chamber, and the red-hot element is accommodated in the outer cylinder (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2022-145103 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] Conventionally, since a glass cylindrical outer cylinder is manufactured as an integral member, there is a problem that the degree of freedom in the design of the outer cylinder is low.

[0005] An object of the present invention is to solve the above-mentioned problem and provide a heating device capable of increasing the degree of freedom in the design of an outer cylinder that accommodates a red-hot element. [Means for Solving the Problem]

[0006] To solve the aforementioned problems, the present invention provides a heating device comprising a box-shaped exterior member, a combustion section and an exhaust section provided within the exterior member, wherein the exterior member has a radiant chamber with an open front. Inside the radiant chamber are an outer cylinder, a red-hot body housed within the outer cylinder, and a reflector positioned behind the outer cylinder. An opening at one end of the outer cylinder is connected to the exhaust section, and an opening at the other end of the outer cylinder is connected to the combustion section. The outer cylinder is formed by joining a plurality of walls with connecting members, and at least one of the walls is made of glass.

[0007] In the heating device of the present invention, various shapes of outer cylinders can be formed by joining multiple wall bodies, thereby increasing the design freedom of the outer cylinder. In the heating device of the present invention, since at least one surface of the outer cylinder is made of glass, the range in which the inside of the outer cylinder can be seen is widened. Furthermore, since the red-hot components can be seen through the glass wall, the visual sensation of heating can be improved. In addition, in the heating device of the present invention, the combustion state of the combustion section can be checked through the glass wall. Furthermore, the joining members in this invention are not limited, and heat-resistant adhesives or metal parts can be used.

[0008] In the aforementioned heating device, if the outer cylinder is formed in a rectangular or hexagonal shape, when transporting or storing multiple outer cylinders together as separate parts, the planes of the outer cylinders can be overlapped to stabilize them and reduce the overall volume. Furthermore, if the outer cylinder is rectangular in shape, it is easier to stabilize the outer cylinder even when both ends are positioned laterally, thus increasing the degree of freedom in the layout of the combustion section, exhaust section, and outer cylinder.

[0009] Furthermore, if the outer cylinder is formed in a rectangular shape, the corners of the outer cylinder are formed by the joints between the side edges of adjacent walls, and a cylindrical red-hot body is placed in the center of the outer cylinder. This increases the distance between the joints between the walls and the outer surface of the red-hot body, thereby suppressing the thermal influence on the joints between the walls.

[0010] In the aforementioned heating device, if the glass wall is placed on the front side of the radiant chamber, the glowing red-hot body becomes easier to see, improving the visual sense of heating and making it easier to check the combustion state of the combustion section.

[0011] In the aforementioned heating device, when the glass wall is placed on the front side of the radiant chamber and the metal wall is placed on the rear side of the radiant chamber, mainly near-infrared rays are radiated forward from the red-hot body through the glass wall. Also, mainly far-infrared rays are radiated backward from the heated metal wall, and these far-infrared rays are reflected by the reflector and radiated forward. As a result, the surface of the body can be rapidly warmed by near-infrared rays, and the core of the body can be effectively warmed by far-infrared rays.

[0012] In the aforementioned heating device, if irregularities are formed on the surface of the glass wall, the whitening of the glass wall due to combustion in the combustion section becomes less noticeable. For example, by creating an uneven surface on the glass wall positioned on the front side of the radiation chamber, and keeping the surface of the glass wall positioned on the rear side of the radiation chamber flat, it is possible to make the whitening of the outer cylinder less noticeable while still allowing sufficient infrared radiation to be emitted. Furthermore, the design of the outer cylinder can be enhanced by creating patterns through irregularities formed on the surface of the glass wall. [Effects of the Invention]

[0013] In the heating device of the present invention, the design freedom of the outer cylinder can be increased by combining multiple wall bodies. Furthermore, in the heating device of the present invention, at least one surface of the outer cylinder is made of glass, allowing the red-hot body to be seen, thereby improving the visual sense of heating and allowing confirmation of the combustion state of the combustion section.

MODE FOR CARRYING OUT THE INVENTION

[0015] Embodiments of the present invention will be described in detail with appropriate reference to the drawings. In the description of each embodiment, the same constituent elements are denoted by the same reference numerals, and repeated descriptions are omitted.

[0016] [First Embodiment] The heating device 1 of the first embodiment, as shown in Figure 1, is a radiant stove that uses the heat generated by burning fuel (for example, kerosene) to radiate infrared rays into the room.

[0017] The heating device 1 is equipped with a metal, box-shaped exterior member 2. A radiant chamber 30 is formed in the center of the exterior member 2. The top, bottom, left, right, and rear surfaces of the radiant chamber 30 are formed of metal plates. The front of the radiant chamber 30 is open to the front (front) of the exterior member 2. Furthermore, as shown in Figure 2, the heating device 1 includes a combustion unit 10 housed in the lower part of the exterior member 2 and an exhaust unit 20 provided at an appropriate location within the exterior member 2.

[0018] The combustion unit 10 is a pot-type heat source and comprises a cylindrical body 11, a bottomed cylindrical pot 12 housed within the cylindrical body 11, a fuel supply nozzle 13 for supplying fuel to the bottom surface of the pot 12, an ignition heater 14 located at the bottom of the pot 12, and an air supply unit 15 for supplying air to the bottom of the cylindrical body 11. As shown in Figure 1, the upper end of the combustion unit 10 protrudes from the center of the bottom surface of the radiant chamber 30.

[0019] In the combustion section 10, as shown in Figure 2, the fuel supplied to the bottom of the pot 12 from the fuel nozzle 13 is vaporized by the heat of the ignition heater 14. In addition, the mixture of air supplied into the cylindrical body 11 by the air supply section 15 and the vaporized fuel is ignited by the heat of the ignition heater 14, causing combustion to occur at the upper end of the pot 12.

[0020] As shown in Figure 1, the radiation chamber 30 contains a cylindrical outer cylinder 40A, a red-hot body 50 housed inside the outer cylinder 40A, and a reflector 60 positioned behind the outer cylinder 40A. The reflector 60 is a metal plate that forms the left and right sides and the rear of the radiation chamber 30.

[0021] The red-hot body 50 is a cylindrical metal component. The peripheral wall of the red-hot body 50 is formed in a mesh pattern. As shown in Figure 2, the red-hot body 50 is suspended from the top surface of the radiation chamber 30 and is positioned directly above the upper end of the combustion section 10. The red-hot body 50 is heated by the combustion section 10 and becomes red-hot.

[0022] The exhaust section 20 includes a heat dissipation channel 21 and an exhaust pipe 22 provided within the outer casing member 2. The heat dissipation channel 21 is formed inside the upper part of the outer casing member 2. At the top surface of the radiant chamber 30, the intake port 21a of the heat dissipation channel 21 protrudes from the portion above the red-hot body 50. The intake port 21a is a cylindrical vent. One end of the exhaust pipe 22 is in communication with the heat dissipation channel 21. The exhaust pipe 22 extends outside the exterior member 2 through an opening formed in the rear wall of the exterior member 2.

[0023] As shown in Figure 3, the outer cylinder 40A is a rectangular tubular member made of glass. In the first embodiment, the outer cylinder 40A is formed into a rectangular tubular shape by arranging four flat wall bodies 41 on the front, back, left, and right sides (see Figure 4). In this embodiment, all the wall bodies 41 are heat-resistant glass plates. Four corners are formed on the outer cylinder 40A by the joints between the side edges of adjacent wall bodies 41, 41. In addition, four flat surfaces are formed on the outer circumferential surface of the outer cylinder 40A.

[0024] In the first embodiment, both ends of the outer cylinder 40A are arranged in the vertical direction. That is, openings are located at the upper end and lower end of the outer cylinder 40A, respectively. In the first embodiment, adjacent wall bodies 41, 41 are joined vertically to each other, and the upper and lower end openings of the outer cylinder 40 are formed as squares in plan view.

[0025] The side edges of adjacent wall bodies 41, 41 are joined together by a joining member 42A. In the first embodiment, the joining member 42A is a heat-resistant glass paste (adhesive) capable of joining glass materials together. The side edges of the wall 41 are joined together by applying a jointing member 42A (glass paste) to the side edges of the wall 41 and heating the joint where the side edges of adjacent wall 41, 41 are joined together. The type of adhesive used as the jointing member 42A is not limited.

[0026] As shown in Figure 2, the upper end of the outer cylinder 40A is connected to the lower end of the intake port 21a. This allows the upper opening of the outer cylinder 40A to communicate with the heat dissipation passage 21 of the exhaust section 20. The lower end of the outer cylinder 40A is connected to the upper end of the cylindrical body 11. This allows the lower end opening of the outer cylinder 40A to communicate with the internal space of the cylindrical body 11 of the combustion section 10.

[0027] An air passage is formed between the combustion section 10 and the exhaust section 20 by the internal space of the outer cylinder 40A. The internal space of the outer cylinder 40A is airtight with respect to the internal space of the radiant chamber 30. A red-hot element 50 is housed in the central part of the outer cylinder 40A. An annular space is formed between the inner surface of the outer cylinder 40A and the outer surface of the red-hot element 50 (see Figure 3). The combustion gas generated by the combustion in the combustion section 10 is exhausted to the outside through the outer cylinder 40A and the exhaust section 20.

[0028] When heating a room with the heating device 1 of the first embodiment shown in Figure 1, the combustion unit 10 burns to heat the red-hot element 50, causing the red-hot element 50 to glow red. At this time, infrared rays are radiated from the red-hot element 50. In addition, when the combustion unit 10 burns, each wall 41 of the glass outer cylinder 40A is also heated, and heat is radiated from each wall 41.

[0029] In the heating device 1 of the first embodiment, since the entire outer cylinder 40A is made of transparent glass, the range in which the inside of the outer cylinder 40A can be seen is widened. Furthermore, since the red-hot body 50 can be seen through the glass wall 41, the sense of heating can be visually enhanced. In addition, the combustion state of the combustion section 10 can be easily checked through the glass wall 41.

[0030] In the first embodiment, as shown in Figure 3, a cylindrical red-hot body 50 is placed in the center of the rectangular outer cylinder 40A. In this configuration, the distance between the joints of adjacent walls 41, 41 and the outer surface of the red-hot body 50 is greater than the shortest distance between the walls 41 and the red-hot body 50, thus suppressing the thermal influence on the joints of the walls 41, 41.

[0031] In the heating device 1 of the first embodiment, the wall 41 of the outer cylinder 40A shown in Figure 2 is made of glass, and thermal deformation of the wall 41 is suppressed, so the airtightness of the connection between the lower end of the outer cylinder 40A and the combustion section 10, and the connection between the upper end of the outer cylinder 40A and the exhaust section 20 can be improved.

[0032] As shown in Figure 3, the outer cylinder 40A of the first embodiment is formed in the shape of a rectangular tube, and its outer surface is composed of four planes. In this configuration, as shown in Figure 5, when multiple outer cylinders 40A are lined up together as parts during transport or storage, each outer cylinder 40A can be stabilized by overlapping the planes of the outer cylinders 40A. This prevents damage caused by contact between multiple outer cylinders 40A when transporting or storing them together. It also reduces the overall volume when multiple outer cylinders 40A are lined up.

[0033] In the first embodiment, the outer cylinder 40A is formed in a rectangular tubular shape by joining four flat wall bodies 41, as shown in Figure 3. However, in the present invention, various shapes of outer cylinders can be formed by changing the number and shape of the wall bodies. In this way, the present invention increases the degree of design freedom for the outer cylinder.

[0034] Although the first embodiment of the present invention has been described above, the present invention is not limited to the first embodiment and can be modified as appropriate without departing from its spirit. As shown in Figure 3, the outer cylinder 40A of the first embodiment is composed of four flat glass wall bodies 41, but in the present invention, the number and shape of the wall bodies constituting the outer cylinder are not limited. For example, by increasing or decreasing the number of wall bodies, an outer cylinder with a pentagon, octagon, or triangular shape can be formed.

[0035] For example, the outer cylinder 40B shown in Figure 6 is formed in a hexagonal cylindrical shape by six flat wall plates 41. In this configuration as well, as shown in Figure 7, when arranging multiple outer cylinders 40B together, the planes of the outer cylinders 40B can be overlapped to stabilize each outer cylinder 40B. In addition, the overall volume when multiple outer cylinders 40B are arranged together can be reduced.

[0036] In the first embodiment, the outer cylinder 40A uses a flat wall 41, but the shape of the wall 41 is not limited, and as shown in Figure 8, two wall plates 41, 41 bent at a right angle may be joined together to form a rectangular outer cylinder 40C.

[0037] The wall of the present invention is not limited to a flat plate shape; for example, a cylindrical outer cylinder or a semi-cylindrical outer cylinder may be formed using a wall that is curved in an arc shape.

[0038] The joining member 42A of the outer cylinder 40A in this embodiment shown in Figure 3 is a heat-resistant adhesive capable of joining glass materials together. However, the joining member 42A for joining the wall bodies 41, 41 together is not limited, and for example, a heat-resistant metal part may be used as the joining member 42A.

[0039] In the first embodiment, as shown in Figure 1, all four walls 41 constituting the outer cylinder 40A are made of glass, but a combination of glass walls 41 and metal walls 41 may also be used. In this case, it is preferable to place the glass wall 41 on the front side of the radiation chamber 30 and the metal wall 41 on the rear side of the radiation chamber 30. In this configuration, the red-hot body 50 radiates mainly near-infrared rays forward through the glass wall 41. In addition, the heated metal wall 41 radiates mainly far-infrared rays backward, and these far-infrared rays are reflected by the reflector 60 and radiated forward. This allows for rapid warming of the body's surface with near-infrared rays while effectively warming the body's core with far-infrared rays.

[0040] In the hexagonal outer cylinder 40B shown in Figure 6, glass walls 41 and metal walls 41 may be combined. In this case as well, it is preferable to make the three front walls 41 out of glass and the three rear walls 41 out of metal. Alternatively, only the frontmost wall 41 may be made of glass and the other five walls 41 out of metal.

[0041] In the heating device 1 of the first embodiment, both ends of the outer cylinder 40A are arranged in the vertical direction, but the orientation of the outer cylinder 40A is not limited. For example, as shown in Figure 9, both ends of the outer cylinder 40A may be positioned laterally. With a rectangular outer cylinder 40A, it is easier to stabilize even when both ends are positioned laterally, thus increasing the degree of freedom in the layout of the combustion section 10 (see Figure 2), exhaust section 20 (see Figure 2), and outer cylinder 40A.

[0042] As the wall 41 of the outer cylinder 40A in the first embodiment shown in Figure 1, patterned glass with irregularities formed on the outer surface (surface) of the glass wall 41 may be used. In this case, the whitening of the glass wall 41 due to combustion in the combustion section 10 becomes less noticeable. Furthermore, by creating an uneven surface on the glass wall 41 located on the front side of the radiation chamber 30, and making the surface of the glass wall 41 located on the rear side of the radiation chamber 30 flat, the whitening of the outer cylinder 40A can be made less noticeable while still allowing sufficient infrared radiation to be emitted. Furthermore, the design of the outer cylinder 40A can be enhanced by creating a pattern through the irregularities formed on the surface of the glass wall 41.

[0043] [Second Embodiment] Next, a heating device of the second embodiment will be described. The heating device of the second embodiment has substantially the same configuration as the heating device 1 of the first embodiment (see Figure 1), but the configuration of the joining member 42B of the outer cylinder 40D is different, as shown in Figure 10. In the second embodiment, the outer cylinder 40D is formed by joining two front and rear wall bodies 41, 41 with two metal joining members 42B, 42B.

[0044] The front wall 41 has a flat plate portion 41a and side plate portions 41b, 41b that extend rearward from the left and right edges of the front flat plate portion 41a. The rear wall 41 has a flat plate portion 41a and two side plate portions 41b, 41b that extend forward from the left and right edges of the flat plate portion 41a. The front and rear walls 41, 41 are each formed in a U shape when viewed from above. The edges of the side plate portions 41b, 41b of the front and rear walls 41, 41 are arranged to abut each other, so that the front and rear walls 41, 41 are arranged in a rectangular tubular shape.

[0045] As shown in Figure 11, the joining member 42B of the second embodiment is a metal rod-shaped member. Grooves are formed on the front and rear surfaces of the joining member 42B into which the edges of the side plate portion 41b of the wall body 41 are inserted. In the outer cylinder 40D of the second embodiment, the front and rear wall bodies 41, 41 are joined together as shown in Figure 10 by inserting the edges of the side plate portions 41b of the wall body 41 into the front and rear grooves of the two connecting members 42B, 42B on the left and right sides. With such an outer cylinder 40D, the wall bodies 41, 41 can be joined together quickly. Furthermore, when a metal joining member 42B is used, the walls 41, 41 can be easily joined together even if one wall 41 is made of glass and the other wall 41 is made of metal.

[0046] Although a second embodiment of the present invention has been described above, the present invention is not limited to the second embodiment, and, as with the first embodiment, can be modified as appropriate without departing from its spirit. In the outer cylinder 40D of the second embodiment, as shown in Figure 10, the two front and rear wall bodies 41, 41 are joined by two left and right joining members 42B, 42B. However, as shown in Figure 12, the four U-shaped wall bodies 41 in the front, rear, left, and right directions may be joined by four joining members 42B in the front, rear, left, and right directions. The outer cylinder 40E shown in Figure 12 is formed in the shape of an octagonal rectangular tube.

[0047] Alternatively, as shown in Figure 13, the cylindrical outer cylinder 40F may be formed by joining two semi-circularly curved front and rear wall bodies 41, 41 together with two connecting members 42B, 42B on the left and right sides. [Explanation of symbols]
