The following will describe the usage mode and the achievable effect of the present invention with reference to the drawings.

As shown in FIG. 9, first, before being used, the first door panel 231, the second door panel 232, and the third door panel 233 are all in a closed position. Therefore, the first door panel 231 completely closes the open end 2121 of the feed pipe 212, and an inner side of the second door panel 232 abuts an outer side of the third door panel 233, so that the second door panel 232 and the third door panel 233 are completely closed together The open end 2131 of the intake pipe 213. At this time, the chamber 111 does not contain any liquid, and no firewood 100 is placed on the deflector 25.

As shown in FIG. 10, a water inlet end of the water inlet pipe 15 is used to connect a conveying pipe 101, the conveying pipe 101 is connected to a cold water bucket (not shown), a first on-off valve 102 is provided on the conveying pipe 101; the first outlet A water outlet of the water pipe 16 is used to connect a first drain pipe 103, the first drain pipe 103 is connected to a hot water equipment (not shown), and a second on-off valve 104 is provided on the first drain pipe 103.

After the first on-off valve 102 is opened, the cold water provided by the cold water bucket passes through the delivery pipe 101 and the water inlet pipe 15 in sequence, then flows out from the water outlet end of the water inlet pipe 15 and flows down to the top surface of the tray body 24 by gravity . The cold water flows along the top surface of the bevel-shaped disk body 24 to the inner peripheral side of the disk body 24. After passing through the notches 241 on the inner peripheral side of the disc body 24, the cold water flows toward the base 13 along the outer side of the chimney 22. It should be noted that the water level in the chamber 111 must be maintained below the tray body 24, so as to allow a certain space above the chamber 111 to contain steam.

As shown in FIG. 11, the first door panel 231, the second door panel 232 and the third door panel 233 are in an open position, so that the first door panel 231 fully opens the open end 2121 of the feed pipe 212, the second door panel 232 and the third door panel 233 The open end 2131 of the intake pipe 213 is fully opened together. The user can put the firewood 100 from the open end 2121 of the feed pipe 212, and the firewood 100 slides down into the combustion space 2111 along the feed pipe 212 by gravity, and is stuck on the flow guiding device 25. The user may place some flames 105 on the top surface of the base 13 along the intake pipe 213 and ignite the flames 105 so that the fire of the flames 105 further ignites the firewood 100.

Since the first door panel 231 fully opens the open end 2121 of the feed pipe 212, and the second door panel 232 and the third door plate 233 together fully open the open end 2131 of the intake pipe 213, the outside air enters through the feed pipe 212 at the maximum flow rate The combustion space 2111 and the outside air enter the combustion space 2111 through the intake pipe 213, the intake space 2112, and the guide holes 253 in sequence at the maximum flow rate. Therefore, the combustion space 2111 can obtain the maximum flow of oxygen for the combustion of the firewood 100, so that the firewood 100 burns fiercely and generates hot smoke with extremely high temperature.

As shown in FIG. 11, because the firewood 100 and sufficient oxygen fully perform a combustion reaction, all combustible substances contained in the firewood 100 can release the heat of the firewood 100 after being combined with oxidation, so that the firewood 100 is fully utilized, And can produce clean hot smoke. The heat released by the firewood 100 and the heat of hot smoke can be transmitted to the cold water in the chamber 111 through the side wall of the combustion tube 211, the outer wall of the spiral part 221, and the outer wall of the straight tube part 222, thereby gradually raising the temperature of the cold water to boiling And produce steam. After rising through the steam hole 121, the steam is discharged outward. As the hot smoke ascends through the spiral portion 221 of the chimney 22, a whirlwind is formed along the spiral inner wall surface of the spiral portion 221. After the cyclone-shaped hot smoke rises through the straight cylindrical portion 222, it is discharged outward.

The user may additionally install a steam duct (not shown) on the steam hole 121, and the steam duct guides the steam to a stove (not shown). In this way, users can use steam to cook food on the stove.

When the present invention is installed indoors (for example, a barn), hot smoke can be used as a heater to fill the entire indoor space, so that the temperature of the indoor space rises, so that the present invention becomes a heating device.

As shown in FIG. 10, after the second on-off valve 104 is opened, hot water passes through the first drain pipe 103 to the hot water equipment. The hot water device may be a faucet for providing hot water in the bathroom, a device for extracting essential oil, or a device for boiling milk. However, the above-mentioned several types of hot water equipment are for illustrative purposes only, and are not limited thereto.

Importantly, when the first door panel 231 stays anywhere between the open position and the closed position, the closer the first door panel 231 is to the open end 2121 of the feed pipe 212, the outside air enters the combustion space 2111 through the feed pipe 212 The smaller the flow rate is, conversely, the farther the first door plate 231 is from the open end 2121 of the feed pipe 212, the greater the flow rate of outside air into the combustion space 2111 through the feed pipe 212. When the second door panel 232 is in the closed position and the third door panel 233 stays anywhere between the open position and the closed position, a gap 237 is formed between an outer side surface of the second door panel 232 and an inner side surface of the third door panel 233 (See FIG. 12) The slit 237 communicates with the intake pipe 213. The closer the third door plate 233 is to the open end 2131 of the intake pipe 213, the smaller the size of the gap 237, the more the flow of outside air into the combustion space 2111 through the intake pipe 213, the intake space 2112, and the diversion holes 253 in sequence On the contrary, the farther the third door plate 233 is from the open end 2131 of the intake pipe 213, the larger the size of the gap 237, and the outside air sequentially enters the combustion space through the intake pipe 213, the intake space 2112, and the guide holes 253 The greater the flow of 2111. Among them, the greater the air flow into the combustion space 2111, the more fiery the firewood 100 burns, the greater the firepower, and the faster the heating speed; relatively, the smaller the air flow into the combustion space 2111, the weaker the firewood 100 burns, the smaller the firepower , The heating speed is slow.

As shown in FIG. 12, the first door panel 231 is in the closed position, so that the first door panel 231 completely closes the open end 2121 of the feed pipe 212. Therefore, the user cannot put the firewood 100 into the combustion space 2111 from the feed pipe 212, and the outside air cannot enter the feed pipe 212 at the same time. The second door panel 232 is in the closed position. The third door panel 233 stays somewhere between the open position and the closed position, the outer side of the second door panel 232 is quite close to the inner side of the third door panel 233, but the outer side of the second door panel 232 and the inner side of the third door panel 233 The sides are not touching together. At this time, the gap 237 between the outer side of the second door panel 232 and the inner side of the third door panel 233 is maintained at a minimum size, and the outside air passes through the intake pipe 213, the intake space 2112, and the flow guides at the minimum flow rate in sequence. The hole 253 enters the combustion space 2111, and the firewood 100 has the smallest degree of combustion and the smallest firepower, which can maintain the water temperature.

As shown in FIG. 11, the ash 106 generated by burning the firewood 100 is heavier in mass, so the ash 106 can fall down through the diversion holes 253 by gravity to fall on the top surface of the base 13. Because the top surface of the base 13 is an arc-shaped convex surface, the ash 106 can slide down toward the open end 2131 of the intake pipe 213 along the top surface of the base 13 by gravity. As long as the user opens the second door panel 232 and the third door panel 233, the ashes 106 in the intake space 2112 can be removed.

Preferably, as shown in FIG. 1, the cookware 10 further includes a thermometer 17. The thermometer 17 is disposed outside the cookware 10. More specifically, the thermometer 17 is provided on the outer side of the side wall of the body 11 to measure the temperature of the body 11.

The second water outlet pipe 18 penetrates the side wall of the body 11 and is close to the bottom of the body 11. As shown in FIG. 13, an outlet end of the second outlet pipe 18 is used to connect a second drain pipe 107, the second drain pipe 107 is connected to another hot water equipment, and a third on-off valve 108 is provided on the second drain pipe . After the third on-off valve 108 is opened, the hot water passes through the second drain pipe 107 to another hot water equipment.

As shown in FIGS. 1 to 4, in the first embodiment, the pot 10 further includes a safety device 19. The safety device 19 includes a pressure relief tube 191 and a safety valve 192. The pressure relief tube 191 communicates with the chamber 111. Specifically, the pressure relief tube 191 penetrates the side wall of the body 11 and is close to the top of the body 11. The safety valve 192 is disposed at an open end of the pressure relief tube 191 outside the chamber 111. As shown in FIG. 14, when the steam pressure in the chamber 111 is greater than the outside atmospheric pressure, especially when the steam temperature is higher than 115°C, because the cross-sectional area of the steam hole 121 is small, the steam that can be discharged is limited and cannot be timely. The pressure is relieved, so that the safety valve 192 is pushed by the steam pressure to detach from the open end of the pressure relief tube 191 outside the chamber 111. After the safety valve 192 is separated from the open end of the pressure relief tube 191 located outside the chamber 111, the steam in the chamber 111 can be discharged from the pressure relief pipe 191, thereby reducing the steam pressure in the chamber 111 and avoiding the explosion of the invention .

As shown in FIGS. 4 to 6, 9 and 10, in the first embodiment, the stove 20 further includes a plurality of thermally conductive plates 26. The heat-conducting plates 26 surround an outer side surface of the side wall of the combustion tube 211 and are arranged longitudinally. More specifically, each heat-conducting plate 26 is made of a material with good heat-conducting effect, so it has good heat-conducting effect; each heat-conducting plate 26 has a horizontal plate 261, a first side plate 262, and a second side plate 263. The horizontal plate 261 is provided on the side of the combustion tube 211 with respect to the feed pipe 212 and the intake pipe 213, and is inclined upward. The first side plate 262 and the second side plate 263 are respectively provided on the other two sides of the combustion tube 211, one end of the first side plate 262 and one end of the second side plate 263 are respectively connected to the two ends of the horizontal plate 261, the first side plate 262 and the second The side plates 263 are each inclined downward from both ends of the horizontal plate 261. In other words, the structure of each heat conduction plate 26 is U-shaped and inclined. In this way, part of the heat released by the firewood 100 and part of the heat of the hot smoke can be further transferred to the heat-conducting plates 26 through the side wall of the combustion tube 211, and then the heat-conducting plates 26 transfer the heat to the cold water in the chamber 111 To improve the effect of heating cold water.

In summary, the present invention achieves the effect of adjusting the heating power in multiple stages by adjusting the flow rate of the external air into the combustion space 2111 through the feed pipe 212 and the intake pipe 213 in multiple stages, and thus can control the heating rate of the cold water.

Furthermore, the structural design of the present invention is appropriate, so the firewood 100 is easy to ignite and can fully burn the firewood 100, and the heat released by the firewood 100 and the heat of the hot smoke are all transmitted to the chamber 111 through the side wall of the combustion tube 211 The cold water has the advantages of less use of firewood 100 and short heating time.

Please refer to FIGS. 15 and 16, which are a perspective view and an exploded view of a steam hot water boiler according to a second embodiment of the present invention. In the second embodiment, the chimney 22 further includes a dust collecting portion 223. The dust collecting portion 223 has a curved section 2231 and a vertical section 2232. The bending section 2231 has a first end and a second end. The first end of the bending section 2231 is disposed on the top of the straight cylindrical section 222, and the bending section 2231 is bent downward. The vertical section 2232 is provided on one side of the curved section 2231 and communicates with the second end of the curved section 2231. An exhaust port 22321 is opened at the top of the vertical section 2232, and a dust collection port 22322 is opened at the bottom of the vertical section 2232.

Generally speaking, in the early stage of the combustion of the firewood 100, the combustion reaction with oxygen has not been completed, and the hot smoke generated at this time contains dust and hot air. Because the mass of the dust is small, it is easy to be caught in the hot air as the hot air flows. As shown in FIG. 16, after passing through the straight cylindrical portion 222, the cyclone-shaped hot smoke enters the curved section 2231 of the dust collecting section 223, and then passes a bend from the first end of the curved section 2231 and then goes down to the curved section 2231 Direction of the second end. After passing through the second end of the curved section 2231, the hot smoke enters the vertical section 2232. After the hot smoke enters the vertical section 2232, the dust in the hot smoke moves downward along the vertical section 2232 by gravity, and the hot air in the hot smoke flows upward along the vertical section 2232. The dust moving downward by gravity passes through the dust collecting port 22322, leaves the dust collecting part 223, and falls down to the ground or a dust collecting device (for example, a dust bag, not shown). The hot air flowing upward passes through the exhaust port 22321, leaves the dust collecting portion 223, and flows upward to the outside space. In other words, the dust collecting part 223 can further separate the dust and hot air in the hot smoke, so that most of the dust falls down to the ground or is collected in the dust collecting device, so the hot air is almost free of dust and is very clean To reduce air pollution and provide cleaner heating.

The above are only the preferred embodiments for explaining the present invention, and are not intended to restrict the present invention in any form, so that any modification or change made to the present invention under the same spirit of the invention , Should still be included in the scope of protection of the present invention.
