[Technical Field]

[0001] The present invention relates to a stove for viewing flames, and more particularly to a stove for viewing flames that burn gas. [Background technology]

[0002] Gas stoves have traditionally been installed indoors as interior decorations. For example, they are installed on a wall to heat the room while allowing people to enjoy the flames. These gas stoves use a catalyst installed at the top of the device to break down incompletely burned gases and supply warm air into the room.

[0003] Another example of a gas stove is the combustion device disclosed in Patent Document 1. This combustion device comprises a main body and a combustion appliance. A combustion chamber is provided within the main body, with a decorative glass window provided near the front of the combustion chamber and an upper plate provided near the top end of the combustion chamber. The main body is provided with a first air passage and a second air passage, with the first air passage provided on the side of the upper plate opposite the combustion chamber, and an exhaust port formed at the end of the first air passage near the front, adjacent to the decorative glass window. The second air passage is provided near the rear of the combustion chamber, with one end of the second air passage communicating with the combustion chamber, and a communication port formed in the second air passage at a position communicating with the combustion chamber. The communication port is located at a height between both sides near the top and bottom ends of the combustion chamber, and the combustion appliance is provided near the bottom end of the combustion chamber.

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-122648 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, fireplace flames not only warm a room but also have the effect of soothing people's hearts and creating a pleasant atmosphere. Such fireplace flames typically flicker naturally, are roughly triangular in shape, and range in color from yellow to red. If the aforementioned flames could be reproduced in a gas stove, it would be possible to achieve the same soothing sensations felt in a fireplace with simple equipment. However, because flames are natural and somewhat irregular, it is difficult to achieve the desired burning effect. Furthermore, since the device is hung on a wall or pillar, the overall width of the device cannot be made large.

[0006] Therefore, an object of the present invention is to provide a stove for flame appreciation that can produce a flame that imitates a fireplace flame and can be hung on a wall or pillar. [Means for solving the problem]

[0007] (1) The flame-viewing stove of the present invention is a flame-viewing stove that can be hung on a wall / pillar, allowing the viewing of flames while warming the surrounding area, and is equipped with an insulating rear panel and a nearly transparent front panel that allows the internal flame to be seen from the outside, and is equipped with a box body that discharges the air taken in and the gas burned by the air from an upper exhaust port, a gas supply unit that is provided on the lower side of the box body and extends in the left-right direction, and a catalyst unit that is provided at the exhaust port and oxidizes the incompletely burned gas, and is characterized in that the exhaust port is provided approximately in the center in the left-right direction relative to the supply unit in a plan view.

[0008] (2) In such a flame-viewing stove, it is preferable that the space between the front panel and the side wall in front of the supply section be used as an intake port for secondary air flowing into the box body from below.

[0009] (3) It is also preferable that a flange portion extends forward from the front side wall of the supply portion.

[0010] (4) It is also preferable that the supply section is box-shaped and open at the top, and that the supply section is disposed with the top inclined forward.

[0011] (5) It is also preferable that the supply section is box-shaped and has an opening at the top, and that the gas flows upward from below the supply section through the gaps between the granular materials. [Effects of the Invention]

[0012] The ornamental gas stove of the present invention allows you to enjoy a flame like in a fireplace with a gas stove, and also allows you to reduce the dimensions in the width direction (front-to-back direction). [Brief explanation of the drawings]

[0014] [1. Brief description] First Embodiment (Summary) A fireplace flame, for example, captures the viewer's attention with its natural flickering and unpredictable changes, and its warm yellow to red hues evoke feelings of beauty, warmth, security, and homeliness. The ornamental gas stove in this embodiment is designed to be hung on the wall to imitate the flames of the fireplace described above, like a painting, while also warming the room. In particular, the stove in this embodiment imitates a fireplace flame from three aspects: shape, flickering, and color.

[0015] In the following explanation, the longitudinal direction of the gas stove 1 for flame appreciation in Fig. 1a will be referred to as the up-down direction, the lateral direction as the left-right direction, and the thickness direction of the gas stove 1 for flame appreciation in Fig. 1b as the front-to-back direction. These front-to-back, left-to-right, and up-to-down directions are indicated by arrows in the figures.

[0016] [2.Each configuration] (Flame ornamental gas stove 1) An overview of a gas stove for flame appreciation (hereinafter simply referred to as a stove) will be given using Figures 1 and 2. The stove 1 shown in the figures is hung on a wall W or a support H. The stove 1 roughly comprises a box 2, a gas supply unit 6 located on the lower inside of the box 2, and a catalyst unit 10 provided at the exhaust port at the top of the box 2 and which oxidizes incompletely combusted gas. In this embodiment, the supply unit 6 is provided with a plurality of heat-resistant granular materials 6 (see FIG. 6) housed therein.

[0017] (Gas G) The gas G (see FIG. 6) used as fuel is a gas containing carbon. For example, it is propane. Alternatively, hydrocarbons such as butane may be used.

[0018] (Can be hung on a wall or post) In this embodiment, the stove 1 is used by hanging it on a wall W or a support H. For this reason, it is preferable that the device is thin. Also, because it is thin, it is difficult to ensure the depth of a fireplace. In this embodiment, for example, the gas supply unit 6 is elongated in the left-right direction (see Figure 4). The supply unit 6 forms the bottom of the box body 2.

[0019] (Wall W or pillar H) In this embodiment, the stove 1 is mounted on a wall W or a support H inside the room. The wall W is a member having a surface to which the stove 1 can be attached, and includes a wall or a plate-like member. The support H is a rod-like member to which the stove 1 can be attached, and includes a pillar or a pole-like member. The height at which the stove 1 is hung on the wall W may be the same as that of an art exhibit in an art museum, etc. For example, the center of the stove 1 or the transparent portion 4d (see Figure 2) may be set at a height of approximately 140 to 150 cm from the floor so that the entire flame is within the field of view and easy to see, making it easy to appreciate the flame. The stove 1 may be placed and fixed on the floor with some gap between it and the floor, like a fireplace, or may be installed on a wall W or a support H with some gap between it and the floor. The wall W / pillar H may be located outdoors. The wall W / pillar H may be a wall / pillar that is an original structural part of the building, or may be newly installed to hang the stove 1.

[0020] (Wall Plate 15) In this embodiment, the stove 1 is attached to a wall W / post H via a wall plate 15 and a bracket 15a. A base 5, which will be described later, is attached to the wall plate 15, which is installed on the wall W / post H.

[0021] (Box 2) 3 is a schematic cross-sectional view of the stove. The box body 2 shown in the figure includes a back panel (backboard) 3 and a front panel (glass section) 4. In this embodiment, the back board 3 and the glass section 4 are provided on a base 5.

[0022] (Base 5) The base 5 is made up of a back panel 5a, side walls 5b extending forward from the left and right side edges of the back panel 5a, and a top panel 5c extending forward from the upper end of the back panel 5a. A discharge port 5d (see FIG. 4) is formed in the top panel 5c.

[0023] (Position of outlet 5d) In this embodiment, the outlet 5d is formed in approximately the center of the top plate 5c in the left-right direction. Also, in this embodiment, the left-right width of the outlet 5d is approximately 1 / 3 to 1 / 4 of the left-right length of the top plate 5c. However, it may be smaller than 1 / 4.

[0024] (Backboard 3) The backboard 3 is attached so as to overlap the inner surface of the back plate 5a. A plurality of grooves 3a are provided in the vertical direction on the backboard 3. Reference numeral 3b denotes a fixture for attaching the backboard 3 to the base 5. The backboard 3 is made of a material that is heat insulating and heat resistant. In this embodiment, porous ceramic is used as the material for the backboard. Other known materials may also be used. Furthermore, a coating agent is applied to the surface of the backboard. This coating improves the strength of the surface of the backboard. In this embodiment, a ceramic coating agent is applied. The coating agent also emits infrared rays when heated. The coating agent is mainly composed of, for example, zirconium silicate, silicon dioxide, and inorganic pigments. Other known materials may also be used.

[0025] (detail) In this embodiment, the backboard 3 is a vertically long board member measuring 300×400 mm. The ceramic coating agent used in this embodiment is called NK-CRC15. The main components of the coating agent are zirconium silicate, silicon dioxide, and inorganic pigments. It is an inorganic paint that uses alcohol as a solvent. The solid content is 45% by weight. The specific gravity is 1.2. The viscosity is 70 (mPa·s). The coating is applied after removing oil from the base. The coating agent is applied by spraying, with a dry film thickness of 30-60 μm and a coating weight of 60-120 g / m 2 If the film thickness exceeds 60 μm, there is a risk of poor adhesion such as peeling or cracking. After application, it is heated to 200-250°C for approximately 15-20 minutes to harden. The coating agent is heat resistant up to 900-1500°C.

[0026] (Glass part 4) The glass section 4 is located on the front side from which the flame can be viewed. The glass section 4 consists of a glass frame 4b attached to the opening edge of the base 5, a glass panel 4a attached by the glass frame 4b and installed in the opening on the front side of the base 5, and a glass front panel 4c installed to cover the entire unit including the glass panel 4a and the glass frame 4b together with the glass panel 4a. In this embodiment, heat-resistant glass is used for the glass panel 4a and the glass front panel 4c. A gasket 4f is provided between the glass frame 4b and the glass panel 4a. The gasket 4f has a U-shaped cross section and is installed to sandwich the periphery of the glass panel 4a. Double glass may also be used for the gas panel 4a.

[0027] (Glass front panel 4c) In this embodiment, the glass front panel 4c consists of a central transparent portion 4d and a surrounding portion 4e. The flame inside can be viewed through the transparent portion 4d. The surrounding portion 4e is used for decoration. The surrounding portion 4e may be the same as the transparent portion 4d.

[0028] (Supply section 6) In this embodiment, the supply unit 6 also serves as the bottom of the base 5. The area of ​​the supply unit 6 that supplies gas covers almost the entire left-right direction of the base 5. The supply unit 6 is cylindrical with a bottom that opens upward. The cross-sectional shape of the cylindrical part is rectangular. However, the cross-sectional shape is not limited to rectangular. As shown in FIG. 3, in this embodiment, a flange 6a extends from the front side wall of the supply unit 6 to the front side.

[0029] (Secondary air intake 14) Next, explanation will be made with reference to Figure 3. The gap between the tip of the flange 6a and the glass panel 4a is an intake port 14 for secondary air. In this embodiment, a flame 18 (see FIG. 1) is ignited between the insulating backboard 3 and the glass panel 4a. At this time, an air flow (updraft) 17 is generated on the side of the glass panel 4a, preventing the glass panel 4a from becoming excessively heated. This allows the width (front-to-back direction) of the entire device to be reduced. Furthermore, flange 6a acts to somewhat disturb the secondary air. For example, if flange 6a were not provided, the air directed through a narrow gap would spread toward backboard 3. Flame 18 would tend to be drawn toward backboard 3 along the spreading updraft 17a, which could result in an unattractive flame appearance.

[0030] (Installation position of supply unit 6) In this embodiment, the upper portion of the supply unit 6 is tilted forward at an angle α relative to the horizontal axis (left-right direction). In this embodiment, the angle α is 2.34°. The angle α may be changed within a range of approximately 0 to 5°, preferably 0 to 3°. By changing the angle α, the gap of the secondary air intake 14 can be adjusted. Furthermore, since it is tilted forward, the mixed gas of gas G and air can be discharged forward. Furthermore, since it is tilted forward, the gas is sprayed forward, and the flame 18 can be prevented from being drawn toward the backboard 3.

[0031] (Gas supply device 7) Returning to FIG. 2, a gas supply device 7 is provided on the side of the supply unit 6. A supply path 7a (see FIG. 4) extends from the gas supply device 7. The supply path 7a communicates with the bottom of the supply unit 6. Reference symbol 7c denotes a bracket that attaches the gas supply device 7 to the base 5. The gas supply device 7 is provided with an operation unit (knob) 7b for controlling the amount of gas G supplied. In this embodiment, the gas supply device 7 is provided with a primary air intake hole (not shown). The amount of primary air can be adjusted by changing the opening area of ​​the primary air intake hole. A mixture of gas G and air is supplied to the supply unit 6 via a supply path 7a. The gas supply device 7 is also provided with an ignition device (not shown). By turning a knob 7b, the ignition device sends a spark to the mixed gas to ignite it.

[0032] (Side Panel 16) Side panels 16, 16 are attached to the left and right sides of the stove 1. The knob 7b is arranged outside through a hole formed in the side panel 16 (see FIG. 1b).

[0033] (Burner cover 8) Next, explanation will be made using Figures 2 and 3. Note that the granular material 9 is not shown in the figures. A burner cover 8 is housed inside the supply unit 6. The burner cover 8 consists of a ceiling portion and a cylindrical peripheral wall extending downward from its side edge. The burner cover 8 is open at the bottom. In this embodiment, the cross-sectional shape of the peripheral wall is a rectangle that is long in the left-right direction (see Figure 2). Note that the cross-sectional shape is not limited to a rectangle. The burner cover 8 is arranged so as to cover the upper part of the outlet of the supply path 7a. In addition, notches 8a are formed at the lower end of the peripheral wall of the burner cover 8. Multiple notches 8a are formed. The notches 8a serve as outlets for the mixed gas. The notches 8a are formed almost evenly around the entire circumference. This allows the mixed gas to be discharged evenly around the periphery of the burner cover 8. In this embodiment, notches 8a are formed on the left, right, front and rear sides of the peripheral wall. One notch 8a is formed on each of the left and right sides. Three notches 8a are formed on the center, left and right sides of the front and rear sides.

[0034] (granules 9) Granular material 9 (see FIG. 6) is stored inside the burner box 6 with the burner cover 8 installed. In this embodiment, the granular material 9 is arranged around the burner cover 8. The burner cover 8 is installed to prevent the granular material 9 from blocking the mixed gas outlet of the supply unit 6.

[0035] (Shape of granular material 9) The granules 9 are large enough to provide gaps for the mixed gas. However, the size is not limited to this. In this embodiment, vermiculite is used as the material for the granules 6. Other known heat-resistant materials may also be used.

[0036] (catalyst part 10) In this embodiment, the catalyst section 10 comprises a support section and a metal section surrounding the support section. The support section is made of, for example, ceramic. Platinum is supported on the ceramic as a catalyst. The platinum catalyst converts carbon monoxide into carbon dioxide and water, which are then emitted. Note that known materials may be used instead of ceramic. Furthermore, known catalysts that decompose carbon monoxide and other hydrocarbons into gases that are harmless to the human body may be used instead of platinum. In this embodiment, the ceramic portion has a honeycomb shape and has multiple hexagonal passages extending in the vertical direction. The passages may have a circular, triangular, or rectangular cross-sectional shape. In this embodiment, the catalyst portion 10 has an overall shape of a rectangular prism with the long sides extending in the left-right direction. The catalyst portion 10 may have a cross-section of any other shape, including a circle. In this embodiment, the catalyst unit 10 has an overall size of 66 mm in length (longitudinal direction), 134 mm in width (left-right direction), and 26 mm in height (vertical direction). The thickness of the walls of adjacent passages is 0.5 mm. Other dimensions may also be used. The amount of platinum catalyst is preset to an amount that can sufficiently decompose carbon monoxide.

[0037] (Seal part 11, side support 12) A cylindrical seal portion 11 is disposed around the periphery of the discharge port 5d on the upper surface of the top plate 5c. The catalyst portion 10 is housed inside the seal portion 11. Side supports 12, 12 are provided on the left and right sides of the seal portion 11. The side supports 12 connect the seal portion 11 to the top plate 5c.

[0038] (Exhaust duct 13) The exhaust duct 13 is made up of a duct portion 13a and a blowout portion 13b. The duct portion 13a is a cylindrical member having a rectangular cross section, and protrudes forward as it goes upward, increasing its cross-sectional area. 4 will now be used for further explanation. Blowing section 13b is a slit 13c that opens forward. Blowing section 13b is made up of sections 13d, 13d that extend outward to the left and right from the left and right side edges of the upper end of duct section 13a, respectively, and ceiling section 13e that closes the opening at the upper end of duct section 13a and is positioned above the left and right sections with a gap.

[0039] [3.About the fireplace-like flame] (1) Shape Figure 5 shows an example of the shape of the flame inside the stove 1. Reference numeral 17 denotes an ascending air current, and reference numeral 18 denotes the flame. In the stove 1, the supply unit 6 for gas G extends in the left-right direction near the bottom end of the box 2, and the exhaust port 5d is located approximately in the center of the left-right direction relative to the supply unit 6 in a plan view. Therefore, the ascending air current 17 caused by combustion is directed toward the catalyst unit 10 at the upper center of the box 2. The flame 18 tends to form a symmetrical triangle along the ascending air current 17.

[0040] (Relationship with transparent part 4d) Returning to FIG. 1, transparent portion 4d is an opening through which flame 18 can be viewed from the outside. The vertical dimension of this opening is designated Y. Furthermore, the preferred height of flame 18 is designated Y1 (see FIG. 1). In this embodiment, the dimensional ratio Y1:Y is set to 1:1.618. Other dimensional ratios are preferably Y1:Y=1:1.5 to 1.7, and more preferably Y1:Y=1:1.55 to 1.65.

[0041] (Relationship with catalyst part 10) 5, in this embodiment, the ascending air current 17 flows toward the exhaust port 5d, so that the ascending air current 17 is concentrated and heat can be efficiently collected in the catalyst unit 10 provided at the exhaust port 5d, resulting in high efficiency of the catalytic reaction (removal of carbon monoxide). Also, the temperature tends to rise from the early stage of ignition.

[0042] (2) Fluctuations Figure 6 shows an example of the shape of the flame inside the stove 1. Because the gas passes through the gaps between the granular material 9, the gas flow is prevented from becoming uniform, and random areas of sparse or dense mixed gas are generated in the front-to-back and left-to-right directions. This causes the gas to partially clump together, resulting in a high-temperature flame, or the flame 18 to disperse to the front-to-back and left-to-right of the supply unit 6, resulting in a low-temperature flame (see the two-dot chain line, symbol 18a), causing the flame to fluctuate. For example, the 1 / f flame fluctuation is set based on the relationship between the frequency of infrared rays emitted from the flame and the radiation intensity of each frequency, the height of the flame, or the temperature of the flame. For example, the shape of the granular material 9 may be changed to approach the 1 / f flame fluctuation based on the measured wavelength of infrared rays, the radiation intensity, the height of the flame, or the temperature of the flame.

[0043] (3) Color (incomplete combustion) The yellow to red flame is caused by a flame color reaction due to the combustion of carbon, etc., resulting from incomplete combustion of gas, for example. Furthermore, if the flame fluctuates significantly or the heat of the flame decreases, the carbon, etc., may remain unburned, causing soot to form inside the device. In this embodiment, the secondary air intake 14 is a slit-shaped opening extending in the left-right direction. The secondary air flowing in from the intake 14 flows upward along the glass panel 4 from the front side of the flame 18, preventing the flame 18 from fluctuating significantly.

[0044] (Amount of primary air) The amount of primary air mixed with the gas G supplied to the supply unit 6 is preset by the gas supply device 7 so that the flame 18 exhibits a preset warm color. The catalyst unit 10 is also preset to oxidize incompletely combusted gases resulting from the amount of primary air.

[0045] (Color regulations) The color of the flame 18 in this embodiment has RGB values ​​in the ranges of R 215 to 245, G 90 to 115, and B 40 to 45. The primary air amount and secondary air amount are set to satisfy these.

[0046] 4. Other Embodiments In the modifications and other embodiments that will be described below, only the parts that are different from the first embodiment described above will be described, and the same parts will be given the same reference numerals and their description will be omitted.

[0047] (Variation 1) In the first embodiment, a fuel other than hydrocarbon may be used as the gas G. For example, ethanol or hydrogen may be used. When using a gas that does not contain carbon, a mechanism may be provided for mixing a material (such as a metal) that will produce the aforementioned RGB values ​​in the flame color reaction.

[0048] (Variation 2) In the first embodiment, the granular material 9 is stored inside the supply unit 6, but in the second modification, the granular material 9 does not have to be stored.

[0049] (Variation 3) In the first embodiment, the supply portion 6 is provided with a flange portion 6a, but in the third modification, no flange portion 6a is provided.

[0050] (Second embodiment) In the first embodiment, the secondary air intake 14 is formed between the glass panel 4a and the supply unit 6, but in other embodiments, the secondary air intake 14 may be formed in another location. For example, a gap may be provided between the backboard 3 and the supply unit 6, and together with the existing gap 14, the flame may be sandwiched from the front and rear of the supply unit 6. In this case, the flange 6a is thought to make it difficult for the ascending air current flowing in from the gap 14 to spread toward the backboard 3. For this reason, the flange 6a may not be provided. Furthermore, for example, a gap 14 may be formed between the entire periphery of the supply part 6 and the inner periphery of the base 5. This allows the flame 18 to be surrounded by an ascending air current 17, stabilizing the shape of the flame 18.

[0051] (Third embodiment) In the first embodiment, the flange 6a is provided to disrupt the flow of the ascending air current 17, but other disrupting mechanisms may be used. For example, unevenness may be provided on the front side wall of the supply unit 6 or on the glass panel 4a.

[0052] [5. Other] The above-described embodiments can be used in appropriate combination. A moving mechanism may be provided on a flat plate / pillar corresponding to the wall W / pillar H on which the stove 1 is attached, so that the stove 1 can be moved.

[0053] [6. Summary] (1) The flame-viewing stove 1 allows the viewing of the flame 18 while warming the surrounding area, and can be hung on a wall W / pillar H. It has an insulating rear panel 3 and a nearly transparent front panel 4 that allows the internal flame to be seen from the outside, and is equipped with a box body 2 that discharges the air it takes in and the gas burned by the air from an upper exhaust port 5d, a gas supply section 6 that is located on the lower side of the box body 2 and extends in the left-right direction, and a catalyst section 10 that is provided at the exhaust port 5d and oxidizes incompletely burned gas, and is characterized in that the exhaust port 5d is located approximately in the center of the left-right direction relative to the supply section 6 in a plan view. As a result, the rising air current 17 is directed toward the exhaust port 5d, creating a beautiful rising flame. The rising air current directed toward the exhaust port 5d also efficiently collects heat in the catalyst unit 10 located at the exhaust port, increasing the efficiency of the catalytic reaction (removal of carbon monoxide). The temperature also tends to rise from the initial stage of ignition.

[0054] (2) In this type of flame-viewing stove 1, the space between the front panel 4 and the side wall in front of the supply section 6 is used as an intake for secondary air 17 flowing into the box 2 from below. This allows a flame 18 (see Figure 1) to burn between the insulating backboard 3 and the glass panel 4a, creating an air flow (updraft) 17 toward the glass panel 4a. The glass panel 4a is less likely to become overheated by the updraft 17. This allows the overall width of the device to be reduced.

[0055] (3) Furthermore, because the flange 6a extends forward from the front sidewall of the supply unit 6, the flange 6a can somewhat disturb the secondary air. For example, if the flange 6a were not provided, the ascending air current 17a would spread toward the backboard 3. The flame 18 would tend to be drawn toward the backboard 3 along the spreading ascending air current 17a, which could result in an unattractive appearance. The flange 6a disturbs the air flow flowing into the box body 2, preventing the flame 18 from being drawn toward the backboard 3, and stabilizing the shape of the flame 18.

[0056] (4) Furthermore, the supply unit 6 is box-shaped and opens upward, and is positioned so that the upper part is tilted forward, which prevents the flame 18 from being drawn toward the backboard 3, thereby stabilizing the shape of the flame 18.

[0057] (5) Furthermore, the supply unit 6 is a box-shaped container that stores a plurality of heat-resistant granular materials 9 and is open at the top. The gas G flows upward from the bottom of the supply unit 6 through the gaps between the granular materials 9, preventing the flow of the gas G from becoming uniform and randomly generating sparse or dense portions of the mixed gas. This causes a natural flickering of the flame 18. [Explanation of symbols]
